FIELD OF THE INVENTION

[0003] The present invention generally relates to devices and methods for securing and carrying elongated members, such as golf clubs.

BACKGROUND

[0004] Sets of articles often need to be kept in a case, container or bag to keep the articles together and allow for them to be transported. For example, golf clubs are typically stored and carried loosely in a golf bag. However, golf bags are bulky and not easily carried or stored. In addition, golf bags may not fit easily within a space such as within a trunk of a car and may not be necessary in situations where only a limited number of clubs are needed. Further, carrying clubs within a golf bag in a metropolitan environment or on public transportation to indoor golf centers or golf driving ranges may be difficult or impractical.

[0005] When a limited number of golf clubs are used, such as leaving the bag on the cart for an approach shot or in other situations where the bag is left behind, the clubs are often carried loosely in a user's hand. Carrying or storing golf clubs loosely may be uncomfortable and awkward. Loose golf clubs are prone to being dropped, lost, or strike someone, something, or each other and any additional clubs must be placed on the ground or leaned against an object while one of them is being used.

[0006] There are current products to hold a limited number of clubs. For example, there are small "Sunday Bags" which carry a limited number of clubs. However, within the bag, the clubs may not be fully secured and to access the clubs, the bag must be opened and closed, and the bag still adds considerable weight.

[0007] There are also racks and stands to hold a limited number of clubs. However racks do not secure the clubs or allow for portability and the portable stands do not allow for effective storage, organization, or carrying of the clubs. Portable and foldable racks to carry clubs can be heavy and in multiple pieces which may make them difficult to make as well as difficult to use.

[0008] Further, at points of sale, rubber bands and hook and loop straps are sometimes used to secure golf clubs. However, the band and straps must be used toward two ends of the clubs, they are easily breakable, and the clubs are not easily accessible. The hook and loop fasteners of straps are difficult to clean and may wear out. In addition, to access a single club, the bands and straps must be removed or opened resulting in loosening all of the clubs. Quickly accessing a club may be critical when the pace of play is important.

[0009] Accordingly, improved devices and methods for securing and carrying elongated items, such as golf clubs, are desired.

[0040] Referring to Fig. 1, an exemplary shaft holding device of the present invention, generally designated 10, is shown in use with a set of golf clubs each having a shaft 40. According to an embodiment of the present disclosure, a shaft holding device 10 for holding shafts 40 such as the shafts of golf clubs, has the ability to be carried easily in one hand and has one or more slots configured for each shaft 40 to fit snugly within the structure. The shaft holding device 10 may be used to secure shafts 40 for carrying and storage while saving space and allowing for carrying in a single hand of a user. When configured to have a plurality of slots as discussed in further detail below, the shaft holding device 10 may be configured to allow one shaft 40 to be accessed and available for use while keeping other shafts 40 remain secured. The shaft holding device 10 may be configured to carry a variety of shafts 40 have different lengths and diameters. The shaft holding device 10 may be configured to couple to a shaft 40 proximate the center of gravity of the shaft 40 (e.g., proximate the club heads for golf clubs) where the user would tend to grip the shaft 40 without the shaft holding device 10.

[0041] Embodiments of the present disclosure may provide several advantages to a golfer using the shaft holding device 10. For example, the user may carry multiple golf clubs more easily to driving range, in a metropolitan setting, or while approaching with multiple clubs. The shaft holding device 10 may allow a user to store and organize golf clubs more easily and securely when space is limited.

[0042] When golfing, some golfers will carry their putter, wedge, and possibly another club when approaching their ball that is near the green. A golfer may have to try and hold all the clubs at once in an unorganized manner. Once they have chipped onto the green, the golfer must put some clubs down onto the ground while putting. This causes the club heads to get wet and even forgotten or lost near the green. The shaft holding device 10, in some embodiments, may keep the grips dry by propping them up just enough for the grips to stay dry and/or allow the clubs to stand vertical on their own (see Fig. 1). The shaft holding device 10 may include a bright color or colors to visually remind the user to pick up their clubs after the hole is complete. The shaft holding device 10 may also provide an organized and easy way to keep clubs together for quick access and organization within the golf bag itself.

[0043] The shaft holding device 10 may also help keep clubs from clanking together while being transported. The shaft holding device 10 may also contain features for holding accessories such as tees, golf gloves, balls, or other items that may be desired. A shaft holding device 10 tailored specifically for chip and putt courses may provide slots to hold 2 or 3 clubs, a golf glove, a ball marker, and tees. Such a device may increase pace of play by keeping the golfers' clubs and accessorizes organized and easily accessible throughout the course.

[0044] The shaft holding device 10 may hold clubs tightly near the heads of the clubs for the best weight balance while carrying and allow three or more clubs to stand vertically on a generally flat surface. The shaft holding device 10 may allow for one-handed carrying of multiple clubs such as 2-6 clubs. The shaft holding device 10 may taper toward the mid-section to allow for more comfortable one handed carrying. The shaft holding device 10 may be generally symmetrical about a mid-section that is perpendicular to the central axis such that the longitudinal orientation of the shaft holding device 10 relative to the shafts 40 does not matter allowing for quick assembly.

[0045] Various embodiments and shapes of the shaft holding device 10 could be used for display of such items in retail or tradeshow environments. The shaft holding device 10 may even be included with the set of clubs being sold. For example, at tradeshows wholesalers sell sets of irons and wrap them in rubber bands to hold them together. The shaft holding device 10 may not only hold these sets of clubs together in a better fashion, but also provide a carrying grip for transport and may provide the wholesaler with a reusable item that can be used to promote their logo and brand.

[0046] The shafting holding device 10 may be adapted to other industries and scenarios. For example, the shaft holding device 10 may be configured to carry and organize a grilling tool set including spatulas, tongs, grill forks, grill brushes, and skewers. The shafting holding device 10 may be configured in latch onto or hang from the grill in some fashion. The shafting holding device 10 could alternatively be configured to hold pool cues, fishing rods, and/or ski, hiking and tent poles.

[0047] Referring to the drawings in detail, wherein like reference numerals indicate like elements throughout, there is shown in Figs. 2A-13B additional views of an exemplary shaft holding device 10. Various embodiments of the shaft holding device 10 are described in further detail below in reference to the exemplary embodiment shown in the figures.

[0048] Referring to Figs. 2A-2H, the shaft holding device 10 includes a body 12 having a top 12a and a bottom 12b and a central axis A ₁ extending between the top 12a and the bottom 12b. The shaft holding device 10 may be generally elongated such that a length L of the body 12 measured along the central axis A ₁ is larger than a largest dimension Di measured perpendicular to the central axis A ₁ . In one embodiment, the length L of the body 12 is at least two times larger than the outermost diameter Di. In one embodiment, the length L of the body 12 is less than about 6 inches and the outermost diameter Di is less than about 2.5 inches. In one embodiment, the length L of the body 12 is approximately 5.5 inches and the outermost diameter Di is approximately 2.2 inches. In one embodiment, the length L of the body 12 is approximately 5 inches to approximately 6 inches. In one embodiment, the diameter Di is approximately 1 inch to approximately 3 inches. The body 12 may be slightly longer than a width of a palm of an average adult male. In one embodiment, the shaft holding device 10 is roughly the size of a soda can. The body 12 may taper radially inwardly toward the mid-section between the top 12a and bottom 12b. In one embodiment, the outermost diameter D ₂ proximate the mid-section of the body 12 is about 2 inches while the outermost diameter Di proximate the top and bottom ends 12a, 12b is about 2.2 inches.

[0049] The body 12 may be generally cylindrical in shape. In one embodiment, the body 12 is generally a hyperboloid shaped. In one embodiment, the body 12 is generally hour glass shaped. The tapered shape of the body 12 may help improve grip, particularly for users with smaller hands. In other embodiments, the body 12 is any desirable shape such as rectangular, hexagonal prism, or triangular prism. In other embodiment, the body 12 includes indents, ribs or ridges to help a user grip the shaft holding device 10 in one hand. One or more portions of the side surface of the body 12 may include indicia 12d such as a logo, message, initials, and/or picture allowing for

customization, promotion, and/or decoration. In one embodiment, the indicia 12d is interchangeable by, for example, including a removable plate that snap fits to the side of the body 12.

[0050] The body 12 may form a plurality of slots 14 each configured to releasably secure a shaft 40 therein (see Fig. 1). In one embodiment, each slot 14 has a generally circular cross section. The slots 14 may also be referred to interchangeably as apertures or grooves. Each of the plurality of slots 14 may have an axis A ₂ spaced from and generally parallel with the central axis Ai. In some embodiments, the axes A ₂ of the slots 14 may be at an oblique angle relative to the central axis A ₁ . For example, the axes A ₂ of the slots 14 may be at an oblique angle relative to the central axis A ₁ such that the aperture is closer to the axis A ₁ toward a bottom end 12b than a bottom end 12a of the body 12 such that there is enough room for thicker grips 40b that would otherwise interfere with one another when attached to the shaft holding device 10. In some embodiments, such an angle is considered "generally parallel". In other embodiments, the axes A ₂ of the slots 14 are precisely parallel to the central axis A ₁ . Each of the plurality of slots 14 may be open along a side of the body 12 such that a shaft 40 may be inserted radially into each slot 14. The openings 14a the slots 14 may be partially circumferentially closed such that the shaft 40 must expand the opening 14a to allow for the shaft 40 to be inserted in the slot 14. Said another way, for each cross section along the length of the body 12 taken about a plane perpendicular to the central axis Ai, each inner circumferential width Wi of an opening 14a of each of the plurality of slots 14 is smaller than a diameter D ₃ of each of the plurality of slots 14. In one embodiment, the inner circumferential width Wi of an opening 14a is generally constant along the length of the slot 14. In one embodiment, the inner circumferential width W ₁ of an opening 14a is approximately 0.374 inches. The inner

circumferential width Wi of an opening 14a may slightly taper toward a mid-section of the body 12. In one embodiment, the width Wi of an opening 14a tapers slightly from approximately 0.349 inches proximate an end of the body 12 to approximately 0.304 inches toward the mid-section of the body 12.

[0051] The shape of the slot 14 may snap fit around the shaft 40 to form a sturdy securement requiring more than an incidental force to remove the shaft 40 from the shaft holding device 10. In some embodiments, one or more slots 14 includes a flap or latch that closes at least a section of a slot 14 around the entire diameter of the shaft 40 once the shaft 40 is in place to further secure the shaft 40 in the slot 14. In one embodiment, one or both ends 12a, 12b of the body may include a locking mechanism that is rotated about the central axis Al to close at least a portion of each slot 14 and retain the shaft 40 in the slot 14 unless the locking mechanism is released.

[0052] Referring to Figs. 2B and 2G, the slots 14 may be shaped to allow for easier insertion of a shaft 40 and improved retention. The cross sectional shape of the aperture 40 may generally correspond to the shaft 40. In one embodiment, the cross sectional shape of the aperture 40 is generally circular. In one embodiment, the diameter D ₃ of each slot 14 is larger toward the top 12a and bottom 12b of the body 12 than the diameter D ₄ at a mid-section of the body 12 between the top 12a and the bottom 12b of the body 12 (see Figs. 2G and 5). In one embodiment, each slot 14 is generally hour glass shaped. This tapering, or flaring in the opposite direction, of the slot diameters D _3; D ₄ may help to retain the shaft 40 in the slot 14 and accommodate shafts 40 having different diameters than one another. In one embodiment, the diameter D ₃ tapers from approximately 0.380 inches proximate one end to the diameter D ₄ of approximately 0.346 inches proximate a mid-section of the body 12 and then flares back to the diameter D ₃ of approximately 0.380 inches proximate another end of the body 12. Though the shaft 40 may contact the entire slot 14 along the length of the slot 14, the shaft 40 may be held most firmly toward the mid-section of the body 12.

[0053] In one embodiment, an outer circumferential width W ₂ of each opening 14a of the plurality of slots 14 is larger toward the top 12a and bottom 12b of the body 12 than at a mid-section of the body 12 between the top 12a and the bottom 12b of the body 12. In one embodiment, the outer circumferential width W ₂ is approximately 0.518 inches towards the ends and approximately 0.374 inches toward the mid-section of the body 12. This tapering, or flaring in the opposite direction, of the opening 14a may result in an angled wall 16 that initially receives the shaft 40 and helps guide the shaft into the slot 14 and allows for an initial insertion of the shaft 40 (and easier for embodiments having a flared slot 14 mentioned above) before snapping the remainder of the shaft 40 into the slot 14. In one embodiment, the angled wall 16 is thicker proximate each end of the body 12 than a mid-section due to the taper of the body 12. In one embodiment, opposing angled walls 16 of an aperture 14 are at an oblique angled relative to one another toward the ends 12a, 12b of the body 12 and are generally parallel to one another toward the mid-section of the body 12 (see Fig. 21). In one embodiment, the angled walls 16 are convexly curved. In one embodiment, the angled walls 16 are flat.

[0054] The body 12 may include one or more slots 14. For example, the body 12 may include one, two, three, four, five, six, seven, eight or more slots 14. The plurality of slots 14 may be spaced equally around the central axis Ai. In other embodiments, as discussed below, the slots 14 may be asymmetrically spaced or bunched toward one side of the body 12. In one embodiment, the plurality of slots 14 include six slots spaced equally around the central axis A ₁ . In one embodiment, each slot 14 is identical to one another. In other embodiments, one or more of the slots are a different size. In one embodiment, five of the six slots 14 are identical and one of the slots 14 has a larger or smaller diameter to secure a differently sized shaft 40. In one embodiment, the differently sized slot 14 is color coded so that it is easily identified. For example, a smaller diameter aperture may be provided for a specific club such as a putter and the walls surrounding the aperture may be colored red while the rest of the body 12 is black to indicate where the putter should be inserted.

[0055] The slots 14 may be generally the same shape in both longitudinal directions (e.g.

symmetrically about plane Pi in Fig. 2A) such that the shafts 40 may be inserted into the slots 14 in either longitudinal direction. Such symmetry may allow a user to use the shaft holding device 10 without having to make sure the shaft 40 is going in a certain direction relative to the shaft holding device 10 for the shaft holding device 10 to function properly. In some embodiments, the shafts 40 are inserted into the shaft holding device 10 in the same longitudinal direction as one another (see Fig. 1). The weight of the club heads 40a extending from one end of the shaft holding device 10 may balance out the weight of the longer shafts extending from the other end of the shaft holding device 10. In other embodiments, the shafts 40 are inserted in various directions relative to one another. Though doing so may increase the length of the assembly, a user may decide to insert clubs in various directions relative to one another to prevent club heads 40a from touching one another or to balance the weight extending from each end of the shaft holding device 10. In other

embodiments, the apertures 14 are asymmetrical in the longitudinal direction (e.g. tapering from one end to another) to better accommodate tapered shafts 40. [0056] Referring to Figs. 3 A-3C, there is an illustration of an exemplary method of inserting a shaft 40 into a slot 14 of the shaft holding device 10. As shown in Fig. 3A, a user may grip the shaft holding device 10 in one hand with a slot 14 facing them. The user may then insert an end of the shaft 40 nearest to the hosel toward an end 12a the shaft holding device 10 such that the shaft 40 is at an oblige angle relative to the central axis A ₁ . The user may use their other hand to press and hold a portion of the shaft 40 in the slot. Referring to Fig. 3B, the user may then pivot the remainder of the shaft toward the shaft holding device 10 until the shaft 40 is generally parallel with the central axis Ai and the shaft 40 is fully inserted into the slot 14. In one embodiment, the shaft 40 snaps into the slot 14 resulting in an audible click. Referring to Fig. 3C, once the shaft 40 is seated in a slot 14 the user may then twist the shaft 40 about the axis A ₂ of the slot 14 until the club head 40a is facing radially away from the central axis A ₁ such that the club head 40a does not contact other club heads and/or helps to act as a base when the clubs are standing vertically (see Fig. 1). To remove a shaft 40 from the shaft holding device 10, the user may grasp the shaft holding device 10 in one hand and pull the shaft away from the shaft holding device 10 using another hand. In one embodiment, the shaft 40 is pivoted away from the shaft holding device 10 relative to the top end of the shaft holding device to release the shaft 40 from the aperture 14 toward the bottom end of the shaft holding device. The shaft 40 may be further pivoted until the entire shaft 40 is released from the aperture 14.

[0057] The body 12 of the shaft holding device 10 may form an open compressible space between each of the plurality of slots 14 such inserting a shaft 40 into a slot 14 reduces the impact on the other slots 14. In one embodiment, the body 12 is formed of a monolithic piece of material. Hollow spaces may be provided between adjacent slots 14 to allow for compression between aperutures. In one embodiment, the body 12 is formed of two or more components coupled together. Spaces and or an internal frame or core may allow for the slots 14 to better retain the shafts 40 and act independent from one another. For example, if the body 12 is formed of a monolithic piece of material with no open spaces between slots, inserting a shaft 40 into each slot 14 may expand each slot 14 and compress one or more of the other slots 14 such that after five shafts 40 have been inserted, it is difficult to insert the last shaft 40 into the sixth slot 14.

[0058] Referring to Figs. 4-7, the body 12 may include a core 18 and an outer sleeve 20 mounted on the core 18. The core 18 may provide a more rigid frame for the softer outer sleeve 20. The core 18 may be comprised of a stiffer material than the outer sleeve 20 and/or be configured to add rigidity in certain areas. The core 18 may have a higher durometer than a durometer of the outer sleeve 20. In one embodiment, the outer sleeve 20 is comprised of an elastomeric material. The outer sleeve 20 may be comprised of silicone rubber. In one embodiment, the outer sleeve 20 has a durometer of 30-90 A. In one embodiment, the outer sleeve 20 has a durometer of 65 A. In one embodiment, the core 18 is comprised of acrylonitrile butadiene styrene (ABS). In one

embodiment, the core 18 has a durometer of 80-100A. In one embodiment, each slot 14 is lined with a material that is different than the material of the outer sleeve 20. For example, each slot 14 may be lined with an even softer elastomeric material. The core 18 and outer sleeve 20 may be configured to isolate each slot 14 to eliminate or reduce the impact of each slot on one another. The core 18 may be configured to help retain the shaft 40 in each slot. The outer sleeve 20 may be configured to provide cushion and a softer material for engaging directly with the shaft 40.

[0059] Referring to Fig. 4, the core 18 may be comprised of a top half 18a and a bottom half 18b that are coupled to one another inside of the outer sleeve 20. The top half 18a and the bottom half 18b of the core 18 may be inserted into either end of the outer sleeve 20 and snap fit and/or be coupled to one another using an adhesive. The core 18 may include radially extending grooves 18c and projections 18d. The radially extending grooves 18c and projections 18d may partially overlap with one another to couple the top half 18a with the bottom half 18b (see Fig. 7). The grooves 18c and projections 18d may also add radial strength to the core 18.

[0060] Referring to Fig. 5, the top half 18a of the core 18 may extend partially from the top of the outer sleeve 20 and the bottom half 18b of the core may extend partially from the bottom of the outer sleeve 20. One or more arms 22 of the core 18 may include a latch 18e configured to extend radially and longitudinally over a top edge 20a of the outer sleeve 20. The top edge 20a may be positioned between two adjacent slots 14. In one embodiment, the top edge 20a has an axially slanted surface. In one embodiment, the core 18 is generally flush with the ends of the outer sleeve 20. In one embodiment, the core 18 is longitudinally recessed within the ends of the outer sleeve 20. The exposed portions of the core 18 may have a distinctive marking or color to form an easily recognizable end cap to help notify users of the location of their clubs and to prevent loss of clubs. The exposed portions of the core 18 may include lights, glow in the dark markings, and/or a tracking device such as a global position system (GPS), Bluetooth, radio-frequency identification (RFID), or low power wide area network (LPWAN) tracker.

[0061] Referring to Fig. 6, the core 18 may include a plurality of arms 22. Each arm 22 may extend longitudinally and project radially from the core 18 in between adjacent slots 14. Each arm 22 may include a split 22a splitting the arm 22 into two longitudinally extending and radially projecting fingers 22b, 22c allowing for the circumferential width W ₃ (see Fig. 7) of each of the plurality of arms 22 to contract in the circumferential direction. Each arm 22 may have a generally Y-shaped cross section. In one embodiment, the fingers 22b, 22c extend circumferentially toward one another at each end to partially close the split 22a. In one embodiment, each arm 22 has a generally hollow end. In one embodiment, the fingers 22b, 22c form a hollow portion having a pie or triangular shaped cross section. The core 18 may have a generally cylindrical base 18f from which the arms 22 extend. In one embodiment, the base 18f is generally hollow.

[0062] In one embodiment, the outer sleeve 20, including the plurality of slots 14, is

symmetrical about three planes Pi, P ₂ , P ₃ , each of the three planes Pi, P ₂ , P ₃ being perpendicular to one another (see Fig. 2B). In one embodiment, the entire shaft holding device 10, except for the mounting features on each end, plurality of slots 14, is symmetrical about three planes Pi, P ₂ , P ₃ , each of the three planes Pi, P ₂ , P ₃ being perpendicular to one another (see Fig. 2B).

[0063] Referring to Fig. 7, when inserting a shaft 40 into a slot, the opening 14a is

circumferentially expanded by the larger diameter of the shaft 40. As the opening 14a expands, the split fingers 22b, 22c of the arm 22 provides some resistance to the expansion but contract toward one another to allow for the expansion but with more resistance than if the arm 22 was not present. Once the shaft 40 is inserted into the slot, the arms 22 expand back toward their initial position and help retain the shaft 40 in the slot 14. In one embodiment, because of the balance between the support of the internal fingers 22b, 22c and the flexibility of the elastomeric outer sleeve 20, the shaft holding device 10 is able to hold most shafts 40 with enough exit force to prevent the shafts 40 from falling out due to their own weight or minor bumps. Because the slots 14 are isolated from each other by way of the rigid arms 22 of the core 18, each slot has a generally consistent entry/exit force for the user, within a certain tolerance regardless of how many slots 14 contain shafts 40. If the arms 22 and the gaps between adjacent slots were omitted, the last shaft 40 inserted into the shaft holding device 10 may have a much higher entry/exit force than the first shaft 40 that was inserted into the shaft holding device 10. The gaps between adjacent slots 14 may allow for a large variety of shaft diameters. The slot 14 may secure shafts 40 having diameters that vary less than 0.5 inches from one another. In one embodiment, the slot 14 secures shafts 40 having diameters that vary less than 0.4 inches from one another.

[0064] The body 12 may be formed from any suitable material, and by any suitable

manufacturing process. For example, shaft holding devices 10 described herein could be made with materials such as rubber, plastic, or other moldable material. In one embodiment, the shaft holding device 10 may be manufactured as a two piece mold, with additional processes performed to assembly the core 18 and add some of the mounting features described below. Exemplary manufacturing processes include, but are not limited to, injection molding, co-molding or over- molding, compression molding, and extrusion or co-extrusion.

[0065] The body 12 may include one or more mounts for attaching accessories to the shaft holding device 10. Because the shaft holding device 10 may be used in place of or away from a golf bag, having mounts, pockets and attachments may be useful to carry certain accessories.

[0066] Referring to Fig. 8, the body 12 may include at least one aperture 24 extending through the bottom. The apertures 24 may be positioned radially closer to the central axis A ₁ than each of the plurality of slots 14. In one embodiment, each aperture 24 is configured to releasably retain a golf tee 26. The golf tees 26 may releasably mount into the slots 24 by a press fit. The apertures 24 may include one or more longitudinally extending and radially projecting compressible ridges 24a to help in retaining the golf tee 26 (see Fig. 2H). In one embodiment, three apertures 24 are provided and are generally spaced around the central axis A ₁ .

[0067] Referring to Figs. 9A-9B, an attachment spike 28 may be provided. The spike 28 may include one or more prongs or projections 28c sized and configured to be releasably press fit into the apertures 24. In one embodiment, the spike 28 includes three generally equally spaced projections 28c. The spike 28 may have a blunt point 28a for inserting into the ground and support the shaft holding device 10 generally perpendicular to a ground surface G (see Fig. 1). The spike 28 may include a plurality of grooves 28b. The grooves 28b may help keep the spike 28 vertical in ground and reduce the amount of material needed saving weight. In one embodiment the spike 28 is about 6 inches to about 12 inches long. The body of the spike 28 may be configured to mount to the shaft holding device 10 using one of the slots 14 when the spike 28 is not being used. Though the shaft holding device 10 may be self-supported, particularly if three or more club heads 40a are used to help balance the assembly and provide at least a tri-pod base, the spike 28 may provide additional support in windy conditions, uneven surfaces, and/or where the club heads 40a do not provide for an even base (e.g., using only two clubs). Keeping the shafts 40 vertical may help locate the clubs and to prevent the grips 40b from getting dirty or wet. In one embodiment, the user may flip the shaft holding device 10 relative to the clubs with the spike mounted on the bottom 12b when transporting the assembly so that the spike 28 extends between the shafts 20.

[0068] Referring to Figs. 2A and 21, the shaft holding device 10 may include a golf ball marker 30 releasably attached to the body 12. The body 12 may include a recess 32 generally sized to accept the golf ball marker 30. The recess 32 may include a mount surface 32b and a further recessed surface 32b. The mount surface 32b may include a magnet 36 that retains the golf ball marker 30 to the body 12.

The length of the hand strap 48 may be adjustable. The hand strap 48 may include pockets and mounts 62 for attaching accessories such as golf tees 26 and ball markers 30.

[0071] Referring to Figs. 12A and 12B, a shoulder strap 56 is shown coupled to the shaft holding device 10. The shoulder strap 56 may releasably couple to a top 12a of the body 12 by attaching to the strap mount 42. In one embodiment, the shoulder strap 54 attaches to the strap mount 42 through a clip 50. The shoulder strap 56 may releasably couple to a bottom 12b of the body 12 by attaching to a hook or loop 52 extending from the bottom 12b of the body 12. In one embodiment, the hook or loop 52 is a projection having one or more openings. The shoulder strap 56 may be attached to the hook or loop 52 using a tie 54. The tie 54 may be tied or looped to the hook or loop 52. In other embodiments, the shoulder strap 56 is attached to the bottom 12b of the body 12 using a clip similar to clip 50 above. The shoulder strap 56 may extend from the top 12a of the body 12 to the bottom 12b of the body 12 and extend over a user's shoulder to allow the shaft holding device to be carried similar to a traditional golf bag. The length of the shoulder strap 56 may be adjustable. The shoulder strap 56 may include one or more pockets 58, rings 60 or mounts 62 for containing and attaching or containing accessories such as golf gloves, towels, hats, golf balls, phones, wallet, keys, golf tees 26 and ball markers 30.

[0072] Referring to Figs. 13 A and 13B a strap mounting accessory 64 may be provided for use with the shaft holding device 10. The strap mounting accessory 64 may quickly and easily be mounted into one of the slots 14 to provide a carrying handle or strap for the shaft holding device 10.
