Docket No.: 8179-0200PCT EXERCISE APPARATUS COMPRISING INNER AND OUTER GLIDERS Cross Reference to Related Application [0001] This PCT application claims the benefit of U.S. Non-Provisional Patent Application Serial No. 17/878,864, filed August 1, 2022, which is hereby incorporated by reference herein in its entirety. Technical Field [0002] The present invention relates generally to exercise apparatuses, and more particularly, to an exercise apparatus which can be used to promote Long Strength Development (LSD) in an exerciser. Background Art [0003] Exercise is an activity that enhances or maintains physical fitness and overall health and wellness. Exercise can improve strength, retard aging, facilitate muscular development and strengthen the cardiovascular system as well as hone athletic skills and facilitate weight loss or maintenance. Furthermore, exercise contributes to reduce stress and relax the mind. Exercise can be conducted either indoors or outdoors in a wide variety of modalities. [0004] The basic types of exercise are aerobic exercise, anaerobic exercise, and flexibility exercises. Aerobic exercise includes any type of physical activity that utilizes large muscle groups, elevates the heart rate, and causes the body to consume more oxygen than it would at rest. One of the purposes of aerobic exercise is to increase cardiovascular fitness. Examples of aerobic exercise include running, cycling, swimming, brisk walking, jumping rope, rowing, hiking, and playing tennis. [0005] Anaerobic exercise includes strength and resistance training and can firm, strengthen, and increase muscle mass and improve bone density, balance, and coordination. Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT Push-ups, pull-ups, lunges, and weight training such as weightlifting, bench press, squats are examples of anaerobic exercise. [0006] Flexibility exercises are slow and carefully timed bodily movements which are undertaken to stretch and lengthen targeted muscles. Flexibility exercises improve joint flexibility and keep muscles limber. Improving joint flexibility improves the range of motion of a joint, thereby reducing the chance of injury. [0007] While multiple apparatus are known in the art for carrying out the aforementioned different types of exercises, there remains a need in the art for an improved exercise apparatus which may promote Long Strength Development (LSD), which consists in maximizing non-primary-muscles that contribute to allowing the primary muscles and secondary muscles to function properly with minimum compensation of muscles that may have been taking on such responsibilities. Summary of the Invention [0008] The present invention is directed to an exercise apparatus which may promote Long Strength Development (LSD) in an exerciser.

Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. [0066] The present invention is directed toward an exercise apparatus which can be used to promote Long Strength Development (LSD) in an exerciser. Shown throughout the figures is an illustrative and non-limiting example of the invention, hereinafter referred to as exercise apparatus 100. [0067] Referring initially to FIG.1, the exercise apparatus 100 may include an apparatus frame 102. At least one left and right pair of outer gliders 184 may be pivotally mounted on the apparatus frame 102. At least one left and right pair of inner gliders 164, 174 may be pivotally mounted on the apparatus frame 102 inside the left and right pair of outer gliders 184, respectively, as best shown in FIG.2. The outer gliders 184 and the inner gliders 164, 174 may be independently positional between a rearward and outwardly-extended position and a forward and inwardly-retracted position. [0068] With continued reference to FIG. 1, a weight rack 136 may be provided on the apparatus frame 102. The weight rack 136 may include multiple stacked weight plates 146, best shown in FIG. 3. At least one cable and pulley system (not illustrated in order not to obscure the invention) may connect the weight plates 146 of the weight rack 136 to the outer gliders 184 and the inner gliders 164, 174. In some embodiments, the cable and pulley system may include a weight resistance cable and pulley system which connects the weight plates 146 to a first one of the inner gliders 164, 174 and the outer gliders 184 and a counterweight resistance cable and pulley system (not illustrated in order not to obscure the invention) which connects the weight plates 146 to a second one of the inner gliders 164, Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT 174 and the outer gliders 184. The number of the stacked weight plates 146 of the weight rack 136 can be selected for a particular exercise to vary the resistance of the inner gliders 164, 174 and the outer gliders 184 as an exerciser sits or stands between the paired left and right inner gliders 164, 174 and outer gliders 184 and uses his or her arms and/or legs to move the inner gliders 164, 174 and the outer gliders 184 in an arc between the extended and retracted positions. In some embodiments, the first one of the outer gliders 184 and the inner gliders 164, 174 may utilize weight resistance for sagittal and transverse functionality. In some embodiments, a second one of the outer gliders 184 and the inner gliders 164, 174 may utilize counterweight or balance resistance to impart resistance to the arms and/or legs of the exerciser. [0069] In some embodiments, the apparatus frame 102 may include a frame base 104. The frame base 104 may extend along a front-to-back, longitudinal direction x and a left-to- right, transverse direction y of the exercise apparatus 100. As best shown in FIG.3, a frame upright 124 may extend upwardly from the frame base 104, preferably in a vertical direction z which is perpendicular to the longitudinal and transverse directions x and y. The frame upright 124 may be fixedly attached to the frame base 104. The outer gliders 184 and the inner gliders 164, 174 may be pivotally mounted on the frame base 104 and the frame upright 124, as will be hereinafter described. [0070] The frame base 104 may have any design which is suitable for supporting the apparatus frame 102 in an upright position on a flat floor or other support surface generally arranged along a horizontal (x-y) plane. In some embodiments, the frame base 104 of the apparatus frame 102 may include a rear base segment 106. In some embodiments, a front base segment 108 may extend from the rear base segment 106. The rear base segment 106 may be straight and elongated. The front base segment 108 may be polygonal, curved, or combinations thereof. For instance and without limitation, the front base segment 108 of may be circular (e.g., semicircular, as shown). In some embodiments, the rear and front base segments 106 and 108 may form a D-shaped arrangement, facilitating placement of the exercise apparatus 100 adjacent to a wall or other vertical structure or surface. [0071] In some embodiments, the exercise apparatus 100 may be selectively deployable in an extended, functional configuration and a folded, transport or storage configuration Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT (FIGS.13 and 14). In the extended, functional configuration, the frame base 104 may extend fully outward relative to the frame upright 124, maximizing stability provided by the frame base 104. In the folded, transport or storage configuration, the frame base 104 may be collapsed. For instance, pair of front base segment hinges 110 may be provided in the front base segment 108. The front base segment hinges 110 may facilitate collapsing or folding the frame base 104, and thus facilitate selective deployment of the exercise apparatus in the extended, functional configuration and the folded, transport or storage configuration. [0072] As illustrated in FIG.3, in some embodiments, the frame upright 124 may extend from substantially the midpoint of the rear base segment 106 of the frame base 104. Alternatively or additionally, the frame upright 124 may extend from, or be in vertical alignment with, substantially the center of the circular or otherwise curved or otherwise shaped front base segment 106 when observed in top plan view. In some embodiments, such as the present embodiment, all said features are included, i.e. the center of the front base segment 108 is located substantially at the midpoint of the rear base segment 106, as best shown in FIG. 10, maximizing stability of the exercise apparatus 100 in different lateral directions along the x-y plane. [0073] With continued reference to FIG.3, the rear base segment 106 of the frame base 104 may include a widened central area or weight rack platform 112. The weight rack 136 may be provided on the weight rack platform 112 behind the frame upright 124. [0074] The weight rack 136 may have any design which is suitable for the purpose of supporting the weight plates 146 in vertical relationship to each other and vertically movable along the weight rack 136. As further illustrated in FIG.3, in some embodiments, the weight rack 136 may include at least one vertical rack rail 138, 140. The weight plates 146 may be slidably mounted on the at least one rack rail 138, 140. The at least one vertical rack rail 138, 140 may include a pair of spaced-apart side rack rails 138 and may further include a center rack rail 140 extending between the side rack rails 138. An elongated rail connector 142 may terminate the upper ends of and connect the side rack rails 138 and the center rack rail 140 to each other. [0075] With reference to FIGS. 1 and 2, the apparatus frame 102 may include at least one glider support, to which the outer gliders 184 and the inner gliders 164, 174 may be Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT pivotally attached. For instance and without limitation, the at least one glider support may include a base glider support 114, an upper overhead glider support 132, and a lower overhead glider support 130. The base glider support 114 may be provided on the frame base 104 of the apparatus frame 102. The lower overhead glider support 130 and upper overhead glider support 132 may be provided on and carried by the frame upright 124, in spaced-apart relationship with the base glider support 114. The inner gliders 164, 174 may be pivotally attached to the base glider support 114 and the lower overhead glider support 130. The outer gliders 184 may be pivotally attached to the base glider support 114 and the upper overhead glider support 132. In some embodiments, at least one, and more preferably, all of the glider supports 114, 130 and 132 may be generally arched, such as circular, and optionally concentric to the front base segment 108. As best shown in FIG.2, the glider supports 114, 130 and 132 may be parallel to one another and configured to be horizontally arranged when the frame base 104 rests on a horizontal floor or surface. In some preferred embodiments, the glider supports 114, 130 and 132 form part of the apparatus frame 102, i.e. are fixed non- movable relative to the rear base segment 106 and the frame upright 124 of the apparatus frame 102. [0076] As illustrated in FIG.3, in some embodiments, the frame upright 124 may include a pair of frame arms 126 at a top area thereof. The frame arms 136 may be arranged in a V- shaped relationship with one another and forming a Y-shape arrangement with the frame upright 124. The lower overhead glider support 130 and the upper overhead glider support 132 may be supported by the frame arms 126. [0077] In some embodiments, the inner gliders 164, 174 and the outer glider 184 may be selectively mounted at different points along the length of the base glider support 114, the lower overhead glider support 130 and the upper overhead glider support 132. In some embodiments, the glider supports 114, 130 and 132 may include discrete mounting points for selectively mounting the inner gliders 164, 174 and the outer glider 184 and specific, discrete positions therealong. For instance and without limitation, the discrete mounting points may include multiple glider mount openings 116 provided in each glider support 114, 130, 132, and respective pivot pins 182 attaching each inner glider 164, 174 and outer glider 184 to each corresponding glider support 114, 130, 132. Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT [0078] With continued reference to FIG.3, in some embodiments, at least one roller or wheel 118 may be provided on the frame base 104 of the apparatus frame 102, to facilitate rolling the exercise apparatus 100 along the floor or other surface. In some embodiments, the wheel or wheels 118 may be arranged in substantial transverse alignment (along transverse direction y) to facilitate frontward and rearward rolling of the exercise apparatus 100. The wheel or wheels 118 may be provided on the rear base segment 106 of the frame base 104. As illustrated in FIG. 14, the wheel or wheels 118 may render the exercise apparatus 100 transportable on a surface 198 in the folded, transport or storage configuration. In some embodiments, such as the present embodiment, frame base 104 is configured to rest on the ground when the exercise apparatus 100 is in the upright, usage position shown in the figures, and rolling mobility of the exercise 100 apparatus by the wheel or wheels 118 is prevented. In this upright, usage position, the wheel or wheels 118 may, however, touch the ground to facilitate tilting the apparatus from the upright, usage position to a tilted, transport position shown in FIG.14, which will be described in detail hereinafter. [0079] As further shown in FIGS.1 and 2, a seat 156 may be carried by the frame upright 124 of the apparatus frame 102. A backrest 158 may be provided on the frame upright 124 above the seat 156. The seat 156 and backrest 158, if present, may be arranged between and in spaced-apart relationship with the base, lower overhead and upper overhead glider supports 114, 130 and 132, as best shown in FIG.2. In some embodiments, the seat 156 may be selectively deployable between a flat, stowage position, shown for instance in FIG.1, and an extended, functional position, shown for instance in FIG.7. Preferably, in the extended, functional position, the seat is relatively far from being arranged horizontally; for example, the seat 156 may be arranged forming an angle less than or equal to 30 degrees with a vertical plane. A seat frame 150 may be provided on and carried by the weight rack platform 112 of the frame base 104. The seat frame 150 may include a pair of spaced-apart, vertical side seat frame members 152. A panel 154 may extend between the side seat frame members 152. The panel 154 may conceal the weight rack 136. The seat 156 and the backrest 158 may be mounted on the seat frame panel 154 and/or on the frame upright 124. [0080] In some embodiments, the inner gliders 164, 174 may be connected to the aforementioned weight and resistance pulley system, and the outer gliders 184 may be connected to the aforementioned counterweight resistance weight and pulley system. In Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT other embodiments, the inner gliders 164, 174 may be connected to the counterweight resistance weight and pulley system, and the outer gliders 184 may be connected to the weight and resistance pulley system. Yet further embodiments are contemplated without departing from the scope of the present disclosure. [0081] The inner gliders 164, 174 may include a pair of lower inner gliders 164 pivotally attached to the base glider support 114 on the frame base 104 of the apparatus frame 102. The inner gliders 164, 174 may additionally or alternatively include a pair of upper inner gliders 174 pivotally attached to the lower overhead glider support 130 on the frame upright 124 of the apparatus frame 102. The lower inner gliders 164 and the upper inner gliders 174 may be independently pivotable with respect to the apparatus frame 102. [0082] With reference to FIGS.1 and 2, in some embodiments, each of the pair of lower inner gliders 164 may include a proximal segment 166, which may extend radially outward relative to the seat 156, and may be sloped upward. A distal segment 168 may extend at an angle from the proximal segment 166, such that the distal segment 168 extends generally upward, such as along the vertical direction z. A mount flange 170 may terminate the proximal segment 166 of each lower inner glider 164. The mount flange 170 may be suitably configured for pivotal attachment to the base glider support 114. [0083] Each of the pair of upper inner gliders 174 may include a proximal segment 176, which may extend radially outward relative to the seat 156, and may be sloped downward. A distal segment 178 may extend at an angle from the proximal segment 176, such that the distal segment 178 extends generally downward, such as along the vertical direction z. The proximal and distal segments 178 may be generally straight and may form an obtuse angle. A mount flange 180 may terminate the proximal segment 176 of each upper inner glider 174. The mount flange 180 may be suitably configured for pivotal attachment to the lower overhead glider support 130 or the upper overhead glider support 132. Free ends of each upper inner glider 174 and corresponding lower inner glider 164 may be arrangeable to face or vertically align with one another, as shown in FIGS.1 and 2. [0084] As illustrated in FIGS. 7 and 8, in some embodiments, a glider connecting member 194 may be attached to each left or right upper inner glider 174 and each corresponding left or right lower inner glider 164 to facilitate joint movement of each left or Applicant: Jon Bolden Atty.

In a non- limiting example, the glider connecting member 194 may have a plate shape and may be attached to the upper inner glider 174 and corresponding lower inner glider 164 by fasteners 196. [0085] With reference once more to FIGS.1 and 2, each of the pair of outer gliders 184 may include a lower glider segment 186 pivotally attached to the base glider support 114, preferably vertically lower than the mount flange 170 of the corresponding lower inner glider 164 (for instance, by having the mount flange 170 pivotably connected to the base glider support 114 by a spacer). An upper glider segment 188 of the outer glider 184 may be pivotally attached to the lower overhead glider support 130 or the upper overhead glider support 132, via a mount flange 192. An outer glider segment 190 may extend between the lower glider segment 186 and the upper glider segment 188. In some embodiments, the outer glider segment 190 of each outer glider 184 may be curved outwardly, as illustrated, and the outer glider 184 may have a substantial C-shape. The lower glider segment 186 and/or upper glider segment 188 may be rectilinear. For instance and without limitation, the lower and upper segments 186 and 188 are rectilinear and parallel to one another, and configured to be arranged horizontally when the exercise apparatus 100 is in the functional configuration. [0086] In an illustrative application, the exercise apparatus 100 may be deployed in the extended, functional configuration illustrated in FIGS.1-12 for use by an exerciser, and may be placed relatively close to or adjacent to a wall or other structure. The front base segment 108 of the frame base 104 may be extended forward and downward at the respective front base segment hinges 110. The deployed frame base 104 and remaining elements of the apparatus frame 102 impart stability to the exercise apparatus 100 without requiring the exercise apparatus 100 to be secured to the wall. The rear base segment 106 and the front base segment 108 may be placed flat on a floor or other support surface 198 with the frame upright 124 extending vertically from the rear base segment 106 of the frame base 104. [0087] In some applications, the seat 156 may be selectively deployed on the seat frame 150 from the flat, stowage position illustrated in FIGS. 1-6 to the extended, functional position illustrated in FIGS. 7-9. The exerciser may rest part of their weight on the slightly tilted seat 156 while maintaining a standing position, with the exerciser’s back resting Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT against the backrest 158. Alternatively, the exerciser may stand on the support surface 198 in front of the seat 156 and the backrest 158, without engaging with the seat 156 and/or backrest 158. The exerciser may select the quantity of weight which is to be lifted by movement of the lower inner gliders 164 or the upper inner gliders 174. This may be accomplished by, for example and without limitation, inserting a weight pin (not illustrated) between a selected pair of the stacked weight plates 146 which correspond to the desired weight in the weight rack 136, according to techniques known in the art. [0088] With the exerciser’s hands or forearms placed against the upper inner gliders 174, the exerciser may exert inward pressure against the outward resistance which the weight plates 146 of the weight rack 136 apply against the upper inner gliders 174 to move the upper inner gliders 174 from the fully open or outwardly extended position illustrated in FIGS.1- 3 to a more closed or inwardly retracted position illustrated in FIG. 5. Simultaneously, the weight resistance cable and pulley system may transmit the energy applied by the exerciser on the upper inner gliders 174 to the weight rack 136, thereby raising the selected pinned weight plates 146 on the side rack rails 138 and the center rack rail 140 of the weight rack 136. The exerciser may repeat this motion a selected number of times to complete one or more sets. Between sets, the exerciser may adjust the number of weight plates 146, and thus, the amount of weight which is lifted each time. The resistance which the weight plates 146 of the weight rack 136 apply against the arms of the exerciser may exercise and develop the arms and chest of the exerciser. [0089] In some applications, the exerciser may apply the exerciser’s feet or legs against the lower inner gliders 164 and move the lower inner gliders 164 in the same motion from the outwardly extended position illustrated in FIGS. 1-3 to the inwardly retracted position illustrated in FIG.6. The outward resistance which the weight plates 146 of the weight rack 136 apply to the legs of the exerciser may develop the leg muscles of the exerciser. The lower inner gliders 164 and the upper inner gliders 174 may apply weight resistance for sagittal and transverse functionality. [0090] In some applications, the exerciser may choose to interconnect the lower and upper inner gliders 164 and 174 via the glider connecting members 194 and thus operate the lower and upper inner gliders 164 and 174 jointly, such as with both hands and both feet. Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT The resistance that the weight plates 146 of the weight rack 136 apply to the legs and arms of the exerciser via the lower and upper inner gliders 164 and 174 may simultaneously develop the leg, chest and arm muscles, respectively, of the exerciser. [0091] In some applications, the exerciser may exert inward pressure using the exerciser’s feet or hands and arms against the outward resistance which the weight plates 146 of the weight rack 136 apply to the outer gliders 184. The exerciser may move the outer gliders 184 from the open or outwardly extended position illustrated in FIGS.1-3 to a more closed or inwardly retracted position illustrated in FIG. 4. The resistance that the weight plates 146 of the weight rack 136 apply to the legs or arms of the exerciser via the outer gliders 184 may develop the leg or arm muscles, respectively, of the exerciser. [0092] In some applications, the inner gliders 164, 174 and/or the outer gliders 184 may be connected to the weight plates 146 of the weight rack 136 through the counterweight resistance cable and pulley system. The inner gliders 164, 174 and/or the outer gliders 184 may apply a counterweight or balance resistance against the legs or arms of the exerciser. Accordingly, the more weight plates 146 which are stacked on the weight rack 136, the less the resistance applied to the legs or arms of the exerciser. Facilitating an exercise program which offers both weight resistance and counterweight or balance resistance, may contribute to further promote Long Strength Development (LSD) in the exerciser. [0093] When not in use, the exercise apparatus 100 can be selectively deployed from the extended, functional configuration illustrated in FIGS. 1-12 to the folded, transport or storage configuration illustrated in FIGS. 13 and 14. This may be accomplished by folding the front base segment 108 of the frame base 104 at the front base segment hinges 110. As illustrated in FIG.14, the folded exercise apparatus 100 can be tilted and transported on the wheels 118 along the support surface 198 for space-efficient storage in an appropriate location. In some embodiments, the exercise apparatus 100 may include a handle 200 configured to facilitate a user pulling and pushing of the apparatus to roll and maneuver along the ground. For instance and without limitation, a pair of handle members 202 may extend outward from the frame upright 124, such as in opposite directions along the left-to- right, transverse direction y, as best shown in FIGS.1 and 3. Applicant: Jon Bolden Atty. Docket No.: 8179-0200PCT [0094] The illustrative embodiments presented in FIGS. 15-21 present additional features of the exercise apparatus 100. Referring initially to FIG.15, at least two adjustable handle grips 208. Each handle 208 has locked slots of indeterminate length. In the preferred embodiment, the locked slots may be 14 inches. To use the handle grip, the user must first turn a handle grip lever knob 212, which are located on the apparatus frame 102, one for each adjustable handle. The up and down direction of the handle is allowed by the adjustable. The handle adjustment slider which allows the raising and lowering of the handle grip has inseam padding that provide safety and comfort to the user. An alternative interchangeable grip 204 is also provided. [0095] As best shown in FIG. 16, the frame upright 124, may also include at least arm supports 220 that when extended, sit on each side of the back rest 158. Similarly, at least one leg support 228 may be provided on the frame upright 124 as well. A plurality of guides 224 may be used to adjust the gliders 164, 184. The gliders 164, 174 may be adjusted using adjustable buttons 232 on the frame upright 124. Movement may be facilitated by glider connecting cables 236. Additionally, both gliders 164, 184 may include a plurality of locks 164 placed throughout the length of each of the gliders 164, 184.This feature for transverse workouts by allow the user’s upper body to go one direction while the lower half can be locked or have the option of rotating the other direction [0096] As best shown in FIG.21 the frame base 104 may be foldable and may include a locking arm support 240. The locking arm support 240 may include an extendable member which extended out of the support 240 to rest on the ground. [0097] Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
