TECHNICAL FIELD

The present invention relates to track and field athletics, and particularly to a pole vault box for pole vaulting. BACKGROUND ART

Pole vaulting is an ancient pastime steeped in deep tradition. While its exact origins remain unclear, depictions from the Ancient Greeks date as far back as the Fifth Century (B.C.). Since its inclusion in the first modern Olympics, pole vaulting has only continued to grow in popularity. High schools and colleges have driven the popularity, allowing students to earn college scholarships and pursue professional careers.

While pole vaulting may be popular, according to studies in an article in The American Journal of Sports Medicine, pole vaulting has a relatively high risk of direct catastrophic injuries in track and field athletics. Catastrophic Injuries in Pole Vaulters: A Prospective 9-year Follow-up Study, Boden et al., The American Journal of Sports Medicine, Vol. 40, No. 7, 1488-1494, 1488 (July 2012). The article defined "catastrophic injuries" as injuries covering brain hemorrhaging, skull, spine, or pelvic fractures, substantial pulmonary injuries, or intra-abdominal injuries. Id at 1488-1489. During the years 2003 to 2011, 19 catastrophic pole vaulting injuries were acknowledged. Id. at 1490. The majority of these 19 catastrophic injuries occurred by the athlete landing within or in close proximity to the pole vault box, regardless of the presence of a padded collar surrounding the pole vault box or not. Id. at 1492.

In 2003, the National Federation of State High School Associations (NFHS) and the National Collegiate Athletic Association (NCAA) implemented changes to reduce the amount of pole vaulting injuries. It is believed that the most important change implemented by the NFHS and NCAA was increasing the size of the minimum landing pad from 16 feet (ft) X 14 ft to 19 ft 8 inches X 16 ft 5 inches. Id. Additionally, further safety measures were adopted by organizations, including requiring an athlete to wear a protective helmet.

However, as noted by the authors, a helmet may not provide adequate protection for an athlete who falls from a typical pole vaulting height of three meters or more onto a hard surface, such as the hard surface of a pole vault box. Id. While catastrophic injuries resulting from athletes missing the landing pad have decreased since the safety measures implemented by the NFHS and NCAA have taken affect, injuries resulting from athletes falling into the pole vault box itself have more than tripled from 2003 to 2011. Id. at 1493. For example, some reasons for an athlete incorrectly landing in or near the vault box include premature pole release, lack of momentum, and, in at least one documented instance, the vaulting pole of the athlete catching the front lip of the pole vault box during the pole planting stage. Id. at 1491.

In a second more recent survey taken from data at a pole vaulting camp, 422 respondents, about 90% of the 467 participants, indicated they had incorrectly landed in the pole vault box area one or more times. 2012 Pole Vault Survey Results and Data

Interpretation, Johnson et al., Sky Jumpers Vertical Sports Club, 1-4 (2012).

While addressing some safety concerns, present pole vault boxes may not address other safety concerns of pole vaulting. One safety concern relates to present pole vault boxes having a straight linear stop board at the end of the pole slide. A potential danger of having a straight linear stop board occurs when the vaulter is already in flight and the pole is bending. The bending pole could collide with the straight stop board, which can result in a damaged vaulting pole. For example, if the vaulting pole weakens or breaks while the vaulter is in mid- flight, the vaulter could potentially fall straight down into the pole vault box from a considerable height. A second safety concern involving the stop board stems from the angle between the stop board and the rotational ledge, which may contribute to the vaulting pole smacking into the lower region of the stop board.

Another possible issue with present pole vault boxes can arise from the lip located in front of the pole slide. Many pole vault boxes have a thick lip that sticks out in front of the pole slide above the surface of a runway that the runner is traveling down prior to planting the vaulting pole. A possible danger with such lip, since it protrudes out above the ground, is the tip of the vaulting pole catching the lip prior to the vaulter planting the vaulting pole. If the vaulting pole tip were to catch with the lip, the pole vaulter may fall down or perform an improper plant, as well as the vaulting pole may weaken or break from the collision with the front lip.

Finally, present pole vault boxes include those that provide no padding on the box itself, or if padding is present, the padding exists only in certain areas. It has been recorded that a direct fall onto an area of the pole vault box that does not have padding, including falling onto a pole slide area or a sidewall, can measure up to about 10,000 Head Injury Criteria (HIC). HIC is a special unit of measurement that provides a likelihood of a head injury arising from an impact. In comparison, at an HIC value of 1000, about one in six people may suffer a life-threatening injury to their brain and, at an HIC value of 250, athletes may suffer a concussion, for example. If the present day pole vault box does have padding, it generally has padding underneath the pole slide or possibly on the sidewalls. However, in present pole vault boxes, areas such as underneath the lip, underneath the rotational ledge, or behind the stop board remain without padding.

It is desirable that a pole vault box has a non-linear stop board portion to limit incorrect collisions with a bending vaulting pole as a vaulter is in flight. It is further desirable, that a pole vault box have a relatively more obtuse or increased angle between the rotational ledge and the stop board, and it is desirable that a lip in front of the pole slide of the pole vault box is structured to minimize catching the tip of the vaulting pole as the vaulter is planting the vaulting pole, and that the lip is adaptable for insertion into the runway. It is also desirable that padding is present on all or portions of surfaces of the lip, rotational ledge, and stop board. Additionally, the padding can extend above the sidewall and/or one or more portions of the base pan.

Thus a padded pole vault box with curved stop board addressing the aforementioned problems is desired.

DISCLOSURE OF INVENTION

Embodiments of a padded pole vault box with curved stop board are provided to enhance athlete safety. The pole vault box has a base pan with a front edge and a rear edge that are in opposing relation to one another and also has a pole slide, the pole slide descending in a downward direction from the front edge towards the opposing rear edge. The base pan includes a plurality of opposing sidewalls that extend from the front edge to the opposing rear edge in an upward direction from the pole slide. Each sidewall of the plurality of opposing sidewalls extends at an angle with respect to a horizontal axis that is in horizontal relation with respect to the pole slide.

A lip is positioned at the front edge of the base pan and extends inwardly towards the pole slide in a downward direction away from the front edge of the base pan. The lip slopes inwardly towards the pole slide at an angle that is formed by an axis passing through the lip and by the pole slide. The lip is adaptable to be inserted into a runway and can be recessed below the runway, and can have an adhesive on a surface of the lip adjacent to the runway to provide further anchoring of the lip below or at the runway surface. An end plate is positioned at the rear edge of the base pan and includes a robust rotational ledge and a sturdy stop board. The rotational ledge is positioned in conjunction with the pole slide of the base pan, and the stop board is positioned in conjunction with the opposing sidewalls of the base pan and the rear edge of the base pan. The pole slide and/or the sidewalls can also be constructed to be more flexible than conventional pole vault boxes so as to readily deform when impacted by a falling object or body.

The stop board includes a lower region adjacent to the rotational ledge and an upper region adjacent to the lower region of the stop board. The upper region of the stop board curves away from the lower region of the stop board, and the lower region of the stop board is positioned at an angle so as to extend outwardly in relation to the rotational ledge of the end plate.

In embodiments of a pole vault box, a padded material is provided that covers at least one of a portion of an exterior surface of the base pan, a portion of a surface of the lip, and/or a portion of an exterior surface of the end plate and sidewalls.

Also, in embodiments of a pole vault box, the pole vault box can have retro pieces as additions to a pole vault box. A first retro piece can be applied to the stop board, such as to increase the angle between the rotational ledge and the stop board. A first retro piece can also be added to replace an existing stop board, such as a worn or damaged stop board. Further, the first retro piece can have a padded material on the underside/exterior surface to provide for additional shock attenuation. A second retro piece having a pole slide, a lip, and a plurality of opposing sidewalls, can be applied to replace an existing, worn or damaged pole slide, lip, and sidewalls of a pole vault box, and can also have a padded material on the underside/exterior surface to provide further shock absorption, such as between the pole slide and the second retro piece. Also, the first retro piece and the second retro piece can be removably securable so as to be combined with each other or to either or both of the stop board or the pole slide, respectively.

These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

Referring to FIGS. 1-5, a pole vault box 100 is shown. Pole vault box 100 can be implemented into many different settings, including an elevated or in-ground platform, soil, or any other common setting used in a pole vault athletic event. At its widest width, it is desirable for pole vault box 100 to be about 60 cm and at its narrowest width it is desirable for the pole vault box 100 to be about 15 cm. However, these dimensions can be changed to suit the needs of the area where the pole vault box 100 will be implemented or the needs of a particular standard, use, or application, for example.

Typically, the pole vault box 100 will be placed in front of a runway 102, which is an area that permits an athlete to run at an appropriate speed to perform a pole vault.

Runway 102 can be made from a number of different materials, including dirt, grass, concrete, and artificial turf, among others. It is desirable that runway 102, or at least a portion of the runway 102 surrounding the pole vault box 100, be made from a softer material, such as plush grass, as may assist in protecting an athlete that has fallen onto the runway surface 102. Further, pole vault box 100 is configured to be implementable with other pole vaulting safety equipment, including padded box collars or landing pads such as disclosed in U.S. Patent No. 3,965,507, for example, among other equipment.

Pole vault box 100 includes a base pan 104 having a front edge 106 and a rear edge 108. The base pan 104 can also include a pole slide 110, and the pole slide 110 descends in a downward direction from the front edge 106 to the rear edge 108 of the base pan 104. The pole slide 110 is an area that interacts with the vaulting pole as the athlete is performing a plant. As the athlete runs down a runway surface 102, the athlete will begin to shift the position of the vaulting pole from a horizontal orientation to a somewhat vertical orientation by bringing the tip of the vaulting pole down onto and across the downward descending pole slide 110.

The length of the pole slide 110 can vary depending on a particular standard, use, or application. However, the length of a typical pole slide 110 is generally about 100 cm, for example. Since the pole vault box 100 is placed in front of the runway 102, the front edge 106 of the base pan 104 will be near or below the surface of the runway 102, while the rear edge 108 of the base pan 104 as well as a stop board 122 will be below the surface of the runway 102. The depth that the rear edge 108 descends below the surface of runway 102 is at a depth of generally about 20 cm. However, the depth that the rear edge 108 descends below the surface of runway 102 can be adjusted to any appropriate level for a particular standard, use or application, for example.

The base pan 104 is desirably rigid to maintain the desired shape yet flexible so as to deform in response to an impact force. The base pan 104 includes a plurality of opposing sidewalls 112 that extend from the front edge 106 of the base pan 104 to the rear edge 108 of the base pan 104. The plurality of opposing sidewalls 112 extend from the pole slide 110 in an upward direction and extend out at an angle θι with respect to a horizontal axis x that is in a horizontal relation with respect to the pole slide 110, the angle θι being measured from the x axis along an interior surface of the pole slide 110 to an interior surface of a corresponding sidewall 112, such as illustrated in FIG. 3. It is desirable that the value of θι be about 120°.

However, the angle Θ] can be adjusted to any suitable value, as long as the plurality of opposing sidewalls 112 do not interfere with the planting of the vaulting pole in the pole vault box 100 and the angle θι meets a corresponding standard, use or application. Each sidewall 112 of the plurality of opposing sidewalls 112 can have a flared end 114, for example. The flared end 114 can take a rounded shape, or any other shape that would provide a contoured edge. The flared end 114 can enhance safety during pole vaulting, in that a flared edge 114 of the sidewall 112 can assist in further protecting an athlete, such as if the athlete were to directly land onto the sidewall 112.

The base pan 104, including pole slide 110 and the plurality of opposing sidewalls 112, can be made from a number of different materials, including wood, welded sheet steel, galvanized steel, stainless steel, sheet or cast aluminum, fiberglass, or thermoplastic, among others, for example. As an example, the sidewalls 112 can be made from a 16 gauge to a 20 gauge steel material. If thermoplastic is selected for the material to be used, the thermoplastic can be polyethylene, polyurethane, acetyl, nylon, or any other commonly used thermoplastic material. It should be noted that whatever material is selected for the base pan 104 or the pole slide 110 or the plurality of opposing sidewalls 112, that the material be sufficiently rigid and robust enough to withstand the force generated from the vaulting pole striking and sliding down the pole vault box 100 yet flexible so as to absorb the impacts to a degree.

It is also desirable that a softer material, such as a thermoplastic or lightweight sheet metal, be used to provide a more pliable, resilient, or flexible surface, as opposed to a heavyweight plate steel, if the vaulter does fall incorrectly and come into contact with the base pan 104 or the pole slide 110 or one or more sidewalls 112. By using a softer or flexible material, the base pan 104 or the pole slide 110 or the plurality of opposing sidewalls 112 can have more of a softer or resilient yet structurally sound construction.

Continuing with reference to FIGS. 1-5, positioned at the front edge 106 of the base pan 104 is a lip 116. The pole slide 110 can also include the lip 116. The lip 116 slopes inwardly towards the pole slide 110 in a downward direction away from the front edge 106 of the base pan 104. This construction improves structural stability yet allows ample space for flexible or resilient connection to the runway underlayer. The lip slopes inwardly at an angle θ ₂ that is formed by an axis y passing through the lip 116 and by the pole slide 110, as illustrated in FIG. 2.

The value of the angle θ ₂ can be any value less than 90° in order to minimize the lip 116 possibly interfering with the vaulting pole during the pole planting stage. It is desirable that the value of θ ₂ be in the range of about 70° to about 80°, for example. Further, the lip 116 is adapted for positioning at, into and below the surface of the runway 102, as illustrated in FIG. 1, for example. By inserting the outer lower edge 116a of the lip 116 into the runway 102, the outer lower edge 116a of the lip 116 will not be exposed onto the surface of the runway 102, thereby possibly reducing a risk of the tip of the vaulting pole catching against the outer lower edge 116a of the lip 116 as the vaulter is planting the vaulting pole. Further, by inserting the outer lower edge 116a of the lip 116 into the runway 102, pole vault box 100 can provide a flexible connection to the runway 102. It is desirable that the lip 116 be recessed below the runway 102 at a minimum depth of about 0.50 inches so as to reduce the possibility of the lip 116 blocking a vaulting pole from correctly entering the front of the pole vault box 100 or the pole slide 110, such as illustrated in FIG. 1.

Therefore, it is desirable that the outer lower edge 116a of the lip 116 be recessed below the surface of the runway 102 at a depth of about 0.5 inch to about 1 inch, for example. Further, the lip 116 can have an adhesive, such as a suitable glue, epoxy or other fastening material, on a surface of the lip adjacent to the runway, such as can provide a glue edge lip or a glue down lip, for example, to assist in anchoring the lip 116 at, into or below the runway 102, for example. Finally, the lip 116 can be made from a number of different materials, including wood, welded sheet steel, stainless steel, sheet or cast aluminum, fiberglass, or thermoplastic, among others, for example.

The base pan 104 also includes an end plate 118 positioned at the rear edge 108 of the base pan 104. The end plate 118 is formed as a single or unitary piece, such as being integrally formed or as by a combination of a plurality of pieces suitably combined. The end plate 118 can be made from a number of suitable materials, including steel, concrete, fiberglass, or high density plastic, among others, for example. The end plate 118 is desirably constructed from a relatively stiffer material compared to the relatively flexible material used to form the base pan 104 or at least the sidewalls 112 of the base pan 104, since the end plate 118 experiences a substantial amount of impacts during normal use. Thus, the end plate 118 should be relatively stiffer, robust and structurally sound in order to accommodate such impact forces. The end plate 118 includes a rotational ledge 120 and a sturdy stop board 122.

For example, the rotational ledge 120 and the stop board 122 can be formed as a single end plate 118 out of durable and rigid material. By using a rigid and durable material for the stop board 122, the life of the stop board 122 can be prolonged, since the stop board 122 is frequently exposed to forces generated by the high impact of the tip of the vaulting pole. Further, end plate 118 can be removably securable to the base pan 104, for example, in forming the pole vault box 100.

The rotational ledge 120 of the end plate 118 is in conjunction with the pole slide 110 and, therefore, can be integrally formed or combined with the pole slide 110 so as to be positioned typically at a substantially same level or below the pole slide 110, such as depending on a particular standard, use, or application, for example. Adjacent to the rotational ledge 120 is the stop board 122, which includes a lower region 122a and an upper region 122b. It is desirable that the lower region 122a accounts for about 70% of the total size of stop board 122 and that upper region 122b accounts for about the remaining 30% of the total size of the stop board 122. It should be noted that these regions 122a and 122b can vary in size, such as 60% of the stop board 122 is the lower region 122a and 40% of the stop board 122 is the upper region 122b, for example, such as depending on a particular standard, use, or application.

The lower region 122a of the stop board 122 is positioned at an angle Θ3 so as to extend outwardly in relation to the rotational ledge 120 of the end plate 118, the angle Θ3 being measured between an interior surface of the lower region 122a of the stop board 122 and the interior surface of the rotational ledge 120, as illustrated in FIG. 2. The value of the angle Θ3 is in a range of about 105° to about 115°, for example, thereby reducing risks of frictional engagement between the bottom of the bent vaulting pole during the jump and the top of the stop board 122, when the vaulting pole engages the rotational ledge 120.

Also, the lower region 122a of stop board 122 of end plate 118 has a relatively straight, generally linear shape. The upper region 122b of the stop board 122 is adjacent to the lower region 122a and has a shape that curves away from the lower region 122a, such as at a radius of curvature R, such as illustrated in FIG. 2. The curvature and the radius of curvature R of the upper region 122b can be structured of a suitable shape and suitable radius of curvature R, depending on a particular standard, use or application. The radius of curvature R can be structured to provide for a suitable degree curve of the upper region 122b, such as can depend upon a particular standard, use or application, such as a 5 degree curve or curvature, for example. This generally curved shape of the upper region 122b of the stop board 122 also can allow for less of a probability of the vaulting pole grinding against the top of the stop board 122, and can also reduce possible damage to the vaulting pole during the pole vault, since the upper region 122b is at a greater distance away from the bent vaulting pole.

Conventional pole vault boxes typically have a relatively straight edge or corner at the top of the stop board. If the bottom section of the pole abuts this corner during the jump, this type of action increases the chances of nicks and deterioration from friction occurring at the impact point on the pole. Thus, failure or fracture can occur as can lead to potential injury to the vaulter. By having the stop board 122 in a relatively straight, generally linear orientation in the lower region 122a and the stop board 122 including a generally curved orientation for the upper region 122b, the stop board 122 assumes a generally curvilinear shape, as illustrated in FIG. 2, for example.

Further, the upper region 122b of the stop board 122 can have a flared edge 126. The flared edge 126 can be of various suitable shapes, such as rounded, curved, flat, or any other desirable shape, that can assist in minimizing injury to the pole vaulter, as from an incorrect landing, such as when the pole vaulter falls onto the stop board 122. For additional protection, an interior surface of stop board 122 can have a ribbed surface 128 such as ripples or ridges, on an interior surface of the stop board 122. Ribbed surface 128 can be placed on either the lower region 122a or the upper region 122b of the stop board 122 or on both regions 122a and 122b, depending upon a particular standard, use or application, for example. The ribbed surface 128 can allow for friction, against the tip of the vaulting pole, to provide an elevated coefficient of friction, to minimize the occurrence of the vaulting pole incorrectly traveling upward on the stop board 122.

Continuing with reference to FIGS. 1-5, pole vault box 100 can have a padded material 124 added to its various surfaces as a shock absorbing material for shock absorption which can reduce the risk of injury. Padded material 124 can be made from a number of different materials or structures or combinations of materials and/or structures, including, but not limited to, open or closed cell foam, egg shell plastic, rubber, air bladders, gel constructions, metal springs, or resilient loose material such as shredded rubber tires or rubber mulch, for example. The depth, thickness, and amount of cushioning can vary depending on the material selected to be implemented and depending upon a particular standard, use or application, for example. The thickness of the padded material 124 can be on the order of approximately 0.125 inches to approximately 4.00 inches, for example. The padded material 124 can be formed as a single unitary structure or formed of a plurality of pieces. Finally, the padded material 124 can be attached to the appropriate surfaces of the pole vault box 100 by any suitable mechanism or methods, such as including glue, fasteners, and stitching, among others, for example.

Padded material 124 can be arranged and implemented on all components of pole vault box 100 or on selected components or on portions of components of the pole vault box 100, depending on a particular standard, use or application. In the pole vault box 100, the padded material 124 can include various portions or sections of padded material, such as padded material 124a-124f. For example, the lip 116 can have on an interior surface the padded material 124a. Base pan 104 including the pole slide 110 can have on an exterior surface the padded material 124b. Each sidewall 112 of the plurality of opposing sidewalls 112 can have on an exterior surface the padded material 124c. The end plate 118 can have on an exterior surface of the rotational ledge 120 the padded material 124d.

The stop board 122 can have on an exterior surface of the lower region 122a the padded material 124e and can have on an exterior surface of the upper region 122b the padded material 124f. Since the stop board 122 has the lower region 122a and the upper region 122b, the respective padded material 124e and 124f can be placed on one or more of the exterior surface of the lower region 122a and/or the exterior surface of the upper region 122b, or on at least a portion of the lower region 122a or the upper region 122b. Also, in various embodiments, the padded material 124 can be absent from various surfaces or portions thereof of the pole vault box 100, such as discussed in relation to FIG. 8B, for example.

Referring to FIGS. 6-9, an embodiment of a pole vault box 600 is shown. Pole vault box 600 is similar to the pole vault box 100. However, the pole vault box 600 differs in the amount of padding on a stop board 622 in comparison to the padding on the stop board 122 of pole vault box 100. As illustrated in FIGS. 6 and 8A, pole vault box 600 includes a padded material 624f, similar to the padded material 124f, on only an upper region 622b of the stop board 622. As illustrated in FIG. 8B, the stop board 622 can also not include any padded material 624, for example.

Also, the components included in the pole vault box 600, as discussed and as illustrated in FIGS. 6-9, are similar to and correspond to those included in the pole vault box 100, described or illustrated in FIGS. 1-5, and can have a same or similar structure, shape and function and can be formed of same or similar materials or compositions, as those corresponding components discussed and described with respect to the pole vault box 100. Also, similar to the pole vault box 100, pole vault box 600 has a base pan 604 with a front edge 606 and a rear edge 608, a pole slide 610 that descends from the front edge 606 to the rear edge 608, and a plurality of opposing sidewalls 612 that extend from the front edge 606 to the rear edge 608. The base pan 604 can also include the pole slide 610. Each sidewall 612 of the plurality of opposing sidewalls 612 can have a flared end 614, for example. It should be noted that whatever material is selected for the base pan 604 or the pole slide 610 or the plurality of opposing sidewalls 612, that the material be sufficiently rigid and robust enough to withstand the force generated from the vaulting pole striking and sliding down the pole vault box 600 yet flexible so as to absorb the impacts to a degree.

In the pole vault box 600, the base pan 604 also includes an end plate 618 positioned at the rear edge 608 and a lip 616 is positioned at the front edge 606. The end plate 618 includes a rotational ledge 620 and a stop board 622 and can be removably securable to base pan 604, for example, in forming the pole vault box 600. The stop board 622 includes a lower region 622a and the upper region 622b. The lower region 622a has a generally linear shape and the upper region 622b has a generally curved shape that curves away from the lower region 622a. Further, the upper region 622b of the stop board 620 can have a flared edge 626. The flared edge 626 can be rounded, curved, flat, or any other desirable shape that can assist in minimizing injury to the pole vaulter, as from an incorrect landing.

Finally, the interior surface of stop board 622 can have a ribbed surface 628, such as ripples or ridges, on an interior surface of the stop board 622. Ribbed surface 628 can be placed on either the lower region 622a or the upper region 622b of the stop board 622 or on both regions 622a and 622b, depending upon a particular standard, use or application, for example. The end plate 618 is desirably constructed from a relatively stiffer material compared to the relatively flexible material used to form the base pan 604 or at least the sidewalls 612 of the base pan 604, since the end plate 618 experiences a substantial amount of impacts during normal use. Thus, the end plate 618 should be relatively stiffer, robust and structurally sound in order to accommodate such impact forces.

Also, similar to the pole vault box 100, pole vault box 600 can have the padded material 624 added to its various surfaces, or portions of its surfaces, such as for shock absorption and attenuation which can assist in reducing the risk of injury. In an embodiment of the pole vault box 600, the padded material 624 can include various portions or sections of padded material, such as padded material 624a-624d and padded material 624f on the upper region 622b of the stop board 622. Also, padded material 624 can be implemented on various pieces of the pole vault box 600, depending on a particular standard, use or application.

For example, the lip 616 can have on an interior surface the padded material 624a. Base pan 604 including the pole slide 610 can have on an exterior surface the padded material 624b. The plurality of opposing sidewalls 612 can have on an exterior surface the padded material 624c. Also, the end plate 618 can have on an exterior surface of the rotational ledge 620 the padded material 624d. However, as mentioned previously, an embodiment of the pole vault box 600 can either include the padded material 624f on the upper region 622b of the stop board 622, as illustrated in FIGS. 6 and 8 A, or the padded material 624 can be absent from the stop board 622, as illustrated in FIG. 8B, for example.

Similar to the discussion as to the pole vault box 100, each sidewall 612 of the plurality of opposing sidewalls extends at an angle θι with respect to a horizontal axis x that is in horizontal relation with respect to the pole slide 610, as illustrated in FIG. 9. Again, it is desirable that the value of the angle θι be about 120°. However, the angle θι can be adjusted to any suitable value, depending upon the particular standard, use or application, for example.

Also, similar to the discussion of the pole vault box 100, the lip 616 is positioned at the front edge 606 of the base pan 604 and extends inwardly towards the pole slide 610 in a downward direction away from the front edge 606 of the base pan 604. The lip 616 slopes inwardly towards the pole slide 610 at an angle θ ₂ that is formed by an axis y passing through the lip 616 and by the pole slide 610. The value of the angle θ ₂ can be any value less than 90° in order to minimize the lip 616 possibly interfering with the vaulting pole during the pole planting stage. It is desirable that the value of the angle θ ₂ be in the range of about 70° to about 80°, for example.

Also, as discussed in relation to the pole vault box 100, the outer lower edge 616a of the lip 616 is adaptable to be inserted into the runway 102 and can be recessed, for example. In an embodiment, the pole vault box 100 and/or 600 can be recessed into the runway 102 so that none of the top edges are exposed to the surface. By this construction, the user likely will initially fall on the surrounding surface instead of the pole vault box, such as during accidental breakage of the pole, presuming that area surrounding the pole vault box 100, 600 is cushioned, for example. Further, the lip 616 can have an adhesive, such as a suitable glue, epoxy or other fastening material, on a surface of the lip adjacent to the runway, such as can provide a glue edge lip or a glue down lip, for example, to assist in anchoring the lip 616 at, into or below the runway, such as the runway 102, for example. Further, similar to the pole vault box 100, the lower region 622a of the stop board 622 is positioned at an angle Θ3 so as to extend outwardly in relation to the rotational ledge 620 of the end plate 618. Again, the value of the angle Θ3 is in a range of about 105° to about 115°, for example.

Also, similar to the pole vault box 100, the upper region 622b of the stop board

622 is adjacent to the lower region 622a and has a shape that curves away from the lower region 622a, such as at a radius of curvature R, such as illustrated in FIGS. 8 A and 8B. The curvature and the radius of curvature R of the upper region 622b can be structured of a suitable shape and suitable radius of curvature R, depending on a particular standard, use or application. The radius of curvature R can be structured to provide for a suitable degree curve of the upper region 622b, such as can depend upon a particular standard, use or application, such as a 5 degree curve or curvature, for example.

Another embodiment of a padded pole vault box 700 is shown in Figs. 11 A and 11B. In this embodiment, the pole vault box 700 is constructed so as to provide padding around a substantial portion of the pole vault box 700 and desirably leave no top edge of the stiffer portions of the pole vault box 700 exposed. This type of construction provides another level of protection for a falling body by having the resilient material of the padding be the first structure impacted rather than the comparatively stiffer structure of the walls of the pole vault box 700.

As shown in FIGS. 11A and 1 IB, the padded pole vault box 700 is substantially similar to the pole vault box 100 or the pole vault box 600. Also, unless otherwise described or indicated, the components included in the pole vault box 700, as discussed and as illustrated in FIGS. 11A-11B, are similar to and correspond to those included in the pole vault box 100, described or illustrated in FIGS. 1-5, or to those included in the pole vault box 600 as described or illustrated in FIGS. 6-9, and can have a same or similar structure, shape and function and can be formed of same or similar materials or compositions, as those corresponding components discussed and described with respect to the pole vault box 100 or the pole vault box 600. As such, similar reference numbers in the "700" series have been used to designate similar features, and the following description will mostly relate to the differences thereof.

The padded pole vault box 700 includes an outer layer of padded material 724 surrounding the walls of the pole vault box 700, such as a pole slide 710, sidewalls 712, and an end plate 718, the end plate including a rotational ledge 720 and a stop board 722. When assembled, the padded material 724 can be disposed flush or a predetermined distance above the surface of the runway 102. In some instances, at least the padded material 724 in front of the pole vault box 700 is desirably flush so as to minimize risks of accidents from the pole catching on the padded material 724 rather than correctly traveling down the pole slide 710 during a pole vault attempt. Additionally, the front face of the padded material 724 in front of the pole vault box 700 is desirably fixed to the runway 102 via adhesives or fasteners so as can assist in preventing any undesirable movement of the pole vault box 700 within the cavity in which the pole vault box 700 is mounted.

To facilitate a cushioned fall, it is desirable that at least the sidewalls 712 of the pole vault box 700 can be shortened, such as relative to the sidewalls of a typical pole vault box, so that the top edge thereof is disposed below the surface of the runway 102 when installed thereon. Each shorter sidewall 712 can also be provided with a flared end 714 so that the flared end 714 can overlap or be positioned in conjunction with the side padding 724c. Either construction can provide some padded material 724c extending past the top edge of the respective sidewall 712 so as to cushion any impact thereon. The height difference that the padded material 724c extends above the sidewalls 712 can be seen in FIG. 11B where hi substantially corresponds to the height of the sidewalls 712 and represents the height to which the sidewalls 712 extend from a horizontal reference located at a juncture of the rotational ledge 720 and the stop board 722 and h ₂ represents the height to which the padded material 724c extends from the horizontal reference, the height h ₂ being greater than the height hi. Also, as illustrated in FIG. 1 IB, the padded material 724 covers a base pan 704 and covers the end plate 718, the base pan 704 and the end plate 718 extending from the horizontal reference to a given height substantially corresponding to the height hi, the padded material 724 adjacent the base pan 704 and the end plate 718 having a height substantially corresponding to the height h ₂ greater than the given height, for example.

The front of the pole vault box 700 can be similarly configured as the pole vault box 100 or the pole vault box 600 except without the lip. As best seen in Fig. 1 IB, the front edge 706 can be formed adjacent a corresponding padded material 724a and/or padded material 724b. The padded material 724b can be constructed from the same material as the padded material 724 so as to form a uniform resilient covering around the walls of the pole vault box 700. Additionally, the padded material 724b can be provided as a separate layer constructed from resilient material with more or less resiliency than the padded material 724. By this construction, the cushioning afforded by the bottom of the pole vault box 700 can vary throughout the impact process, the variance depending on the resiliencies of the padded material 724 and the padded material 724b. When provided as a separate layer, at least the front portion or face of the padded material 724b can be affixed to the surrounding padded material 724 with adhesives, fasteners, and the like.

As with the sidewalls 712 and the front edge 706 of the pole slide 710, the end plate 718 can also be dimensioned so as to be disposed below the surface level of the runway 102. In all other respects, the end plate 718 is constructed substantially the same as the end plates 618 and 118, and includes the stop board 722, a flared edge 726, and ribbed surface 728. As best seen in Fig. 11B, the end plate 718 extends to a height generally below the height of the surrounding padded material 724 as represented by the greater height h ₂ compared to the lesser height hi. This construction, like the above, assists in insuring that the surrounding padded material 724 cushions the initial impact. The flared edge 726 can also allow the pole to bend naturally without presenting a relatively sharp edge or corner that can potentially erode or rub against the pole and cause premature breakage.

Also, it should be noted that whatever material is selected for the base pan 704 or the pole slide 710 or the plurality of opposing sidewalls 712, that the material be sufficiently rigid and robust enough to withstand the force generated from the vaulting pole striking and sliding down the pole vault box 700 yet flexible so as to absorb the impacts to a degree. The end plate 718 is desirably constructed from a relatively stiff er material compared to the relatively flexible material used to form the base pan 704 or at least the sidewalls 712 of the base pan 704, since the end plate 718 experiences a substantial amount of impacts during normal use. Thus, the end plate 718 should be relatively stiff er, robust and structurally sound in order to accommodate such impact forces.

The pole vault box 700 also includes a reinforcement feature that increases the life of the end plate 718 through repeated use. The end plate 718 of a pole vault box is a structural element that experiences the most amount of wear and impact forces during normal use. The end plate 718 is the part where the pole impacts and plants during a vaulting attempt. As a result, the end plate 718 can wear and deform faster than desired. To increase longevity and durability of the end plate 718, the pole vault box 700 can include an elongate, concrete reinforcement block 730 disposed behind the end plate 718. The block 730 is desirably shaped so that one face thereof conforms to the slanted or sloped disposition of the end plate 718. This provides a relatively flat face, the same generally flat face as the back of the end plate 718, which can buttress the end plate 718 in a relatively wide area. It is desirable that the block 730 covers at least the lower half of the end plate 718, since this is the area that experiences the most amount of impacts. Thus, the block 730 desirably spans at least the width of the end plate 718, for example. In an embodiment, a relatively small layer of the padded material 724f is interposed between the end plate 718 and the concrete reinforcement block 730. This configuration can permit easier distribution of forces in the vertical direction during impacts on the end plate 718 while the block 730 remains steadfast to lateral forces. In other words, the interposed layer of padded material 724f can facilitate a relatively more easier or efficient dampening of the impact forces. It is also contemplated that the block 730 can be placed in direct contact with the back of the end plate 718. However, the dampening effect typically will be less.

Referring to FIG. 10, an exploded perspective view of an embodiment of a pole vault box 1000 is illustrated. Pole vault box 1000 is similar to the pole vault boxes 100, 600 or 700, but pole vault box 1000 can also include a first retro piece 1000a as can be applied to or over or replace a stop board 1022, and a second retro piece 1000b as can be applied to or over or replace a pole slide 1010, a lip 1016 and a plurality of opposing sidewalk 1012 of a base pan 1004, for example, are illustrated.

Also, the components included in the pole vault box 1000, as discussed and as illustrated in FIG. 10, are similar to and correspond to those included in the pole vault box 100, described or illustrated in FIGS. 1-5, are similar to and correspond to those included in the pole vault box 600, described or illustrated in FIGS. 6-9, and are similar to and correspond to those included in the pole vault box 700, described or illustrated in FIGS. 11A- 11B. The components of the pole vault box 1000 can have a same or similar structure, size, shape and function and can be formed of same or similar materials or compositions, as those corresponding components discussed and described with respect to the pole vault boxes 100, 600 or 700.

Further, either or both of the first retro piece 1000a and the second retro piece 1000b can provide a replacement system or a component system for an existing pole vault box, such as to be applied to or over or replace one or more corresponding components of an existing pole vault box, such as for the pole vault boxes 100, 600, 700 and 1000.

Additionally, the first retro piece 1000a and the second retro piece 1000b can be placed together as a component system, such as by being fixed or removably secured, so as to form an entire pole vault box, that, when combined, is similar to the pole vault boxes 100, 600, 700 and 1000, such as by suitable mechanical fasteners, a tongue in groove or interlocking arrangement, a pressure fit, a suitable glue, sealant or adhesive, or a combination thereof, for example. In this regard, the first retro piece 1000a can correspond to all or part of an end plate, such as the end plates 118, 618, 718 and 1018. Also, the first retro piece 1000a and the second retro piece 1000b can include a padded material, as described, that, when combined, can form an entire pole vault box as can include all or part thereof with a padded material.

Also, in a replacement system or a component system as can include one or more of the pole vault box 1000, the first retro piece 1000a and the second retro piece 1000b, the end plate, such as end plate 1018, can act as an anchor of the pole vault box. And the base pan 1004 also includes the end plate 1018 as can be fixed or removably secured to the base pan, such as the base pan 1004, such that the end plate 1018 and the first retro piece 1000a can be fixed to or removably secured from the combination of the base pan 1004 and the second retro piece 1000b, for example.

The first retro piece 1000a and the second retro piece 1000b can be formed as separate pieces from the pole vault box 1000, but, as discussed, are available as additions to the pole vault box 1000. For example, the first retro piece 1000a can be applied to and over or replace a stop board 1022, such as applied to or over or replace the stop board 122 of pole vault box 100 or applied to or over or replace the stop board 622 of pole vault box 600. The first retro piece 1000a can change or adjust, such as increase, an angle θ ₄ between a rotational ledge 1020, such as the rotational ledge 120 of the pole vault box 100 or the rotational ledge 620 of the pole vault box 600, and the stop board 1022, such as the stop board 122 or the stop board 622. Also, the first retro piece 1000a can be used to cover or replace an existing, worn or damaged stop board 1022, such as to cover or replace an existing, worn or damaged stop board 122 of the pole vault box 100 or to cover or replace an existing, worn or damaged stop board 622 of the pole vault box 600, for example. Further, the first retro piece 1000a can include a padded material 1024a as can be used to cover and pad an existing stop board 1022, such as to cover and pad an existing stop board 122 of the pole vault box 100 or to cover and pad an existing stop board 622 of the pole vault box 600, for example.

Also, the first retro piece 1000a includes a lower region 1022a and an upper region 1022b, similar to the lower region 122a and the upper region 122b of the stop board 122 of the pole vault box 100 or similar to the lower region 622a and the upper region 622b of the stop board 622 of the pole vault box 600. It is desirable that the lower region 1022a of the first retro piece 1000a accounts for about 70% of the total size of first retro piece 1000a and that upper region 1022b accounts for about the remaining 30% of the total size of the first retro piece 1000a. It should be noted that the lower region 1022a and the upper region 1022b can vary in size, such as 60% of the first retro piece 1000a is the lower region 1022a and 40% of the first retro piece 1000a is the upper region 1022b, for example, such as depending on a particular standard, use, or application.

Also, the lower region 1022a of first retro piece 1000a has a relatively straight, generally linear shape. The upper region 1022b of the first retro piece 1000a is adjacent to the lower region 1022a and has a shape that curves away from the lower region 1022a, such as at a radius of curvature R'. The curvature and the radius of curvature R' of the upper region 1022b can be structured of a suitable shape and suitable radius of curvature R', depending on a particular standard, use or application, such as can correspond to the radius of curvature of an upper region 1025 of the stop board 1022, such as can be similar to the radius of curvature R of the upper region 122b of the stop board 122 of the pole vault box 100, and such as can such as can be similar to the radius of curvature R of the upper region 622b of the stop board 622 of the pole vault box 600. By having the first retro piece 1000a in a relatively straight, generally linear orientation in the lower region 1022a and in a generally curved orientation for the upper region 1022b, the first retro piece 1000a assumes a generally curvilinear shape, as illustrated in FIG. 10, for example.

Further, the upper region 1022b of the first retro piece 1000a can have a flared edge 1026a. The flared edge 1026a can be of various suitable shapes, such as rounded, curved, flat, or any other desirable shape, that can assist in minimizing injury to the pole vaulter, as discussed with respect to the flared edge 126 of the stop board 122 of the pole vault box 100 or with respect to the flared edge 626 of the stop board 622 of the pole vault box 600.

The first retro piece 1000a can have a same or similar structure, size, shape and function and can be formed of same or similar materials or compositions, as those corresponding to the stop board 1022, and as those corresponding components as discussed and described with respect to the stop board 122 of the pole vault box 100, the stop board 622 of the pole vault box 600 or the stop board 722 of the pole vault box 700.

For example, the first retro piece 1000a can be made from a same, compatible or suitable material as the stop board 1022. For example, if the first retro piece 1000a is attached to or placed over or replaces the stop board 1022 that is made from an aluminum material, then the first retro piece 1000a can be made from an aluminum material, as well. Additionally, the first retro piece 1000a can be respectively made from other suitable or compatible materials, such as from a high density UV plastic or a light weight steel material, among other robust materials, for example, such as depending on a particular standard, use or application. When the first retro piece 1000a is applied to or over or replaces the stop board 1022, the lower region 1022a of the first retro piece 1000a is at the angle θ ₄ with respect to an interior surface of the rotational ledge 1020, the angle θ ₄ being measured between an interior surface of the lower region 1022a of the first retro piece 1000a and the interior surface of the rotational ledge 1020, as illustrated in FIG. 10, and the first retro piece 1000a is positioned at the angle θ ₄ so as to extend outwardly in relation to the rotational ledge 1020 of the end plate 1018, for example. The value of the angle θ ₄ can be the same as or a different value than the angle Q ₃ , such as the angle θ ₄ can have an increased value relative to the angle Q ₃ , depending upon a particular standard, use or application. The value of angle θ ₄ can be in a range of about 105° to about 115°, for example.

The first retro piece 1000a, when applied to or over or replaces the stop board 1022, can be fixed or removably secured to the stop board 1022 by suitable mechanical fasteners, a tongue in groove or interlocking arrangement, a pressure fit, a suitable glue, sealant or adhesive, or a combination thereof, for example. Also, when the first retro piece 1000a replaces the stop board 1022, the replacement can include physically removing the stop board 1022 from the pole vault box 1000, such as cutting out or detaching the stop board 1022 and replacing it with the first retro piece 1000a.

Further, the first retro piece 1000a can have a padded material 1024a, similar to the padded material 124 of the pole vault box 100 or similar to the padded material 624 of the pole vault box 600, on all or a portion of the underside/exterior surface of the first retro piece 1000a, such as can provide for additional shock attenuation. Also, the interior surface of first retro piece 1000a can have a ribbed surface 1028 as, for example, ripples or ridges, such as the ribbed surface 128 on the interior surface of the stop board 122 of the pole vault box 100 or the ribbed surface 628 on the interior surface of the stop board 622 of the pole vault box 600.

As to the second retro piece 1000b, the second retro piece 1000b includes a pole slide 1010b, corresponding to the pole slide 1010, such as the pole slide 110 of the base pan 104 of the pole vault box 100 or the pole slide 610 of the base pan 604 of the pole vault box 600. Also, the second retro piece 1000b can include a lip 1016b, such as the lip 116 of the pole vault box 100 or the lip 616 of the pole vault box 600. Also, when the second retro piece 1000b is used in conjunction with the pole vault box 700, the lip 1016b is typically not included on the second retro piece 1000b, for example. Further, the second retro piece 1000b includes a plurality of opposing sidewalls 1012b, such as the plurality of opposing sidewalls 112 of pole vault box 100 or the plurality of opposing sidewalls 612 of the pole vault box 600.

The second retro piece 1000b including pole slide 1010b, the lip 1016b, and the plurality of opposing sidewalls 1012b, can be applied to or over or replace corresponding components of the pole vault box 1000, such as including the pole slide 1010, a lip 1016 as can be included with the pole slide 1010, and a plurality of opposing sidewalls 1012 as can be included with a base pan 1004 of the pole vault box 1000, such as can be applied to or over or replace the pole slide 110, the lip 116 and sidewalls 112 of the base pan 104 of the pole vault box 100 or can be applied to or over or replace the pole slide 610, the lip 616 and the sidewalls 612 of base pan 604 of the pole vault box 600. The second retro piece 1000b can therefore be used to cover or replace an existing, worn or damaged pole slide 1010, a lip 1016 or a plurality of opposing sidewalls 1012 associated with the base pan 1004, for example.

In the second retro piece 1000b, the lip 1016b extends inwardly towards the pole slide 1010b of the second retro piece 1000b in a downward direction away from the front edge 1006b of the second retro piece 1000b. The lip 1016b slopes inwardly towards the pole slide 1010b at an angle that is formed by an axis passing through the lip 1016b and by the pole slide 1010b for the pole vault box 1000. In this regard, the lip 1016b slopes at an angle Θ5 that is formed by an axis y ^' that passes through the lip 1016b and by the pole slide 1010b. The angle Θ5 is measured from a bottom surface of pole slide 1010b in an outward direction to the y ^' axis, such as shown on pole vault box 1000 and on the second retro piece 1000b illustrated in FIG. 10.

Similar to the value of the angle θ ₂ for pole vault boxes 100 and 600, the value of the angle Θ5 can be any value less than 90° in order to minimize the lip 1016b from sticking straight out and possibly interfering with the vaulting pole during the pole planting stage. It is desirable that the value of the angle Θ5 be in the range of about 70° to about 80°, for example.

Further, when the second retro piece 1000b is applied to or over or replaces the pole slide 1010 including the lip 1016 and plurality of opposing sidewalls 1012, the lip 1016b of the second retro piece 1000b is adapted for positioning into and below the surface of a runway, such as the runway 102 as illustrated in FIG. 1, for example. By inserting an outer lower edge 1017b of the lip 1016b into the runway, such as the runway 102, the outer lower edge 1017b of the lip 1016b will not be exposed onto the surface of the runway, thereby possibly reducing a risk of the tip of the vaulting pole catching against the outer lower edge 1017b of the lip 1016b as the vaulter is planting the vaulting pole. It is desirable that the lip 1016b be recessed below the runway at a minimum depth of about 0.5 inches so as to reduce the possibility of the lip 1016b blocking a vaulting pole from correctly entering the front of the pole vault box 1000 or the pole slide 1010.

Therefore, it is desirable that the outer lower edge 1017b of the lip 1016b is recessed below the surface of the runway at a depth of about 0.5 inch to about 1 inch, for example. Further, the lip 1016b can have an adhesive, such as a suitable glue, epoxy or other fastening material, on a surface of the lip adjacent to the runway, such as can provide a glue edge lip or a glue down lip, for example, to assist in anchoring the lip 1016b at, into or below the runway, such as the runway 102, for example.

The plurality of opposing sidewalls 1012b of the second retro piece 1000b extend from the pole slide 1010b in an upward direction and extend at an angle θ ₆ with respect to a horizontal axis x' that is in a horizontal relation with respect to the pole slide 1010b, such as illustrated in FIG. 10. The angle θ ₆ is measured from an interior surface of the pole slide 1010b to an interior surface of a corresponding sidewall 1012b, similar to the angle θι of pole vault boxes 100 and 600.

It is desirable that the angle θ ₆ be about 120°, similar to the angle θι. However, the angle θ ₆ can be adjusted to any suitable value, as long as the plurality of opposing sidewalls 1012b do not interfere with the planting of the vaulting pole in the pole vault box 1000 and the angle θ ₆ meets a corresponding standard, use or application. Further, each of the plurality of opposing sidewalls 1012b can have a flared end 1014b to provide a contoured edge that can assist in further protecting an athlete if the athlete were to land onto the sidewall 1012b.

The second retro piece 1000b, when applied to or over or replaces the pole slide 1010, the lip 1016 and the plurality of opposing sidewalls 1012, can be fixed or removably secured to the pole slide 1010, the lip 1016 and the plurality of opposing sidewalls 1012 such as by suitable mechanical fasteners, a tongue in groove or interlocking arrangement, a pressure fit, a suitable glue, sealant or adhesive, or a combination thereof, for example.

Also, when the second retro piece 1000b replaces the pole slide 1010, the lip 1016 and the plurality of opposing sidewalls 1012, the replacement can include physically removing the pole slide 1010, the lip 1016 and the plurality of opposing sidewalls 1012 from the pole vault box 1000.

Such removal can include, for example, cutting out or detaching the pole slide 1010 including the lip 1016 and the plurality of opposing sidewalls 1012 from the pole vault box 1000 and replacing the corresponding components with the second retro piece 1000b. Also, when the lip 1016b is not included on or is removed from the pole vault box 1000, the second retro piece 1000b can similarly not include the lip, as well as can be suitably sized to provide a pole vault box similar to the pole vault box 700, for example.

Therefore, the second retro piece 1000b can be used to cover or replace an existing, worn or damaged pole slide 1010 including the lip 1016 and the plurality of opposing sidewalls 1012, such as to cover or replace an existing, worn or damaged pole slide 110 including the lip 116 and plurality of opposing sidewalls 112 of the base pan 104 of the pole vault box 100 or to cover or replace an existing, worn or damaged pole slide 610 including the lip 616 and plurality of opposing sidewalls 612 of the base pan 604 of the pole vault box 600, for example.

The second retro piece 1000b can have a same or similar structure, size, shape and function and can be formed of same or similar materials or compositions, as those corresponding components discussed and described with respect to the pole slide 1010 including the lip 1016 and the plurality of opposing sidewalls 1012 of the base pan 1004 of the pole vault box 1000, such as the pole slide 110 including the lip 116 and the plurality of opposing sidewalls 112 of the base pan 104 of the pole vault box 100, the pole slide 610 including the lip 616 and the plurality of opposing sidewalls 612 of the base pan 604 of the pole vault box 600, or the pole slide 710 and the plurality of opposing sidewalls 712 of the base pan 704 of the pole vault box 700 but without a lip.

Further, the second retro piece 1000b can have a padded material 1024b, similar to a padded material 1024 on the pole vault box 1000 or similar to padded material 124 or the padded material 624, on all or a portion of the underside/exterior surface of the pole slide 1010b including on the underside/exterior surface of the lip 1016b and on the exterior surface of the plurality of opposing sidewalls 1012b, such as to provide for additional shock attenuation, for example.

Also, the second retro piece 1000b including the pole slide 1010b, the lip 1016b and the plurality of opposing sidewalls 1012b can be made from a same, compatible or suitable material as pole slide 1010 including the lip 1016 and the plurality of opposing sidewalls 1012. For example, if the second retro piece 1000b is attached to or placed over or replaces the pole slide 1010 including the lip 1016 and the plurality of opposing sidewalls 1012 that is made from an aluminum material, then the second retro piece 1000b including the pole slide 1010b, the lip 1016b and the plurality of opposing sidewalls 1012b can be made from an aluminum material, as well. Additionally, the second retro piece 1000b can be respectively made from other suitable or compatible materials, such as from a high density UV plastic or a light weight steel material, among other robust materials, for example, such as depending on a particular standard, use or application. Also, the second retro piece 1000b including the pole slide 1010b and the lip 1016b and the plurality of opposing sidewalls 1012b can be made from a number of different materials, including wood, welded sheet steel, stainless steel, sheet or cast aluminum, fiberglass, or thermoplastic, among others, for example.

It should be noted that whatever material is selected for the base pan 1004 or the pole slide 1010 or the plurality of opposing sidewalls 1012 of the pole vault box 1000, or that whatever material is selected for the pole slide 1010b or the plurality of opposing sidewalls 1012b of the second retro piece 1000b, that the material be sufficiently rigid and robust enough to withstand the force generated from the vaulting pole striking and sliding down the pole vault box, such as the pole vault box 1000, yet flexible so as to absorb the impacts to a degree.

Also, the end plate 1018, as can include the rotational ledge 1020 and the stop board 1022, and the first retro piece 1000a are each desirably constructed from a relatively stiffer material compared to the relatively flexible material used to form the base pan 1004 or at least the sidewalls 1012 of the base pan 1004, or compared to the relatively flexible material used to form the pole slide 1010b or the plurality of opposing sidewalls 1012b of the second retro piece 1000b, since the end plate 1018 and the first retro piece 1000a experience a substantial amount of impacts during normal use. Thus, the end plate 1018 and the first retro piece 1000a should be relatively stiffer, robust and structurally sound in order to accommodate such impact forces.

Further, the first retro piece 1000a and the second retro piece 1000b can be formed to match or correspond to the dimensions of the corresponding existing pieces of the pole vault box 1000 that they will be respectively applied to, cover or replace. For example, if the stop board 1022 is approximately 6 inches wide at a lower region 1023 and

approximately 16 inches wide at an upper region 1025, the first retro piece 1000a can have similar corresponding dimensions to those approximate dimensions.

It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
