DETAILED DESCRIPTION

[0042] The present invention is directed toward training ladders, hurdles and methods for using the same. In the following description, numerous specific details are set forth to provide a more thorough description of embodiments of the invention. It will be apparent, however, to one skilled in the art, that the embodiments of the present invention may be practiced without these specific details. In other instances, well known features have not been described in detail so as not to obscure the invention.

[0043] It is noted that, as used in this specification and the appended claims, the singular forms a, an, and the, include plural referents unless expressly and unequivocally limited to one referent. As used herein, the term include and its grammatical variants are intended to be non-limiting, Such that recitation of items in a list is not to the exclusion of other like items that can be substituted or other items that can be added to the listed items.

[0044] As used in this disclosure, except where the context requires otherwise, the term comprise and variations of the term, such as comprising, comprises, and comprised are not intended to exclude other additives, components, integers or steps. Thus, throughout this specification, unless the context requires otherwise, the words comprise, comprising and the like, are to be construed in an inclusive sense as opposed to an exclusive sense, that is to say, in the sense of including, but not limited to.

[0045] As used in this disclosure, except where the context requires otherwise, the method steps disclosed are not intended to be limiting nor are they intended to indicate that each step is essential to the method or that each step must occur in the order disclosed.

[0046] Turning now in detail to the drawings, as shown in FIG. 1 is a training ladder 100 for use on a surface 101, such as the ground. The ladder 100 includes flexible opposed first and second substantially parallel stiles 103, 105 at least two spaced apart rungs 107, 107 between the stiles 103, 105 and connected to the stiles 103, 105 each rung 107, 107 having a first 109 and a second end 111 for connection to each of the stiles 103, 105 and at least one rung 107 having a first clasp 113 in a closed position 117 securing the first end 109 of the rung 107 to the first stile 103 and a second clasp 115 in a closed position 117 securing the second end 111 of the rung 107 to the second stile 105, where in the closed position 117 the rung 107 with the clasps 113, 115 cannot be moved along the stiles 103,105. Each clasp 113, 115 has an open position 119 to reposition the rung 107 on the stiles 103,105 or to remove the rung 107 from the stiles 103, 105. The rungs 107, 107 spaced apart for exercise. The open and closed positions 117, 119 of the clasps 113, 115 are shown in FIGS. 2 and 3.

[0047] Preferably the stiles 103, 105 of the ladder 100 are made of a flexible material meaning the stiles 103, 105 can be folded up, collapsed, rolled-up, or bent backwards so the ladder 100 can be conveniently stored in a compact arrangement. Examples of flexible materials include, but are not limited to string, rope, cord, fabric, elastic, or nylon webbing. Flat webbing is not preferred because it can become twisted if the ladder 100 is not stored correctly. Therefore, in a preferred embodiment, the stiles 103, 105 are composed of cord or rope providing a substantially circular cross section 121. The length of the stiles 103,105 will depend on the number of rungs 107, 107 in that fewer rungs 107, 107 will require less length and conversely more rungs 107, 107 requires greater stile 103, 105 length. In a preferred embodiment, the length of each stile 103, 105 is approximately 10 to 20 feet and in a most preferred embodiment the length of each stile 103, 105 is between 12 and 17 feet. One continuous length of material can be used to configure the two parallel opposed stiles 103, 105 however two pieces of material can also be used so long as each stile 103, 105 is parallel to each other to accommodate the rungs 107, 107 in between.

[0048] Unlike the stiles 103, 105 the rungs 107, 107 are preferably constructed from a more rigid material such as plastic. Plastics such as polypropylene may be used to provide lightweight rungs 107, 107 with sufficient strength and stiffness to endure repeated stepping on. However, the rungs 107, 107 can also be formed using other suitable materials such as metal, rubber or a combination of different materials. Each rung 107, 107 is generally a flat, planar elongated beam with two ends a first rung end 109 and a second rung end 111. When the rungs 107, 107 are flat, they can be stacked in a compact arrangement for convenient storage. Preferably, the rungs 107, 107 have a rectangular cross section, although square, round and other shapes can be used. Shapes having rounded edges, such as a rectangle with curved shorter sides, instead of flat sides and sharp corners can also be used. In a preferred embodiment, the length 102 AA of the ladder rungs 107, 107 can range from about 10 inches to 20 inches and in a most preferred embodiment the length of the rungs 107, 107 is between 15 to 17 inches.

[0049] The ladder shown in FIG. 1 has rungs 107, 107 equally spaced apart about 16 inch centers. However, the rungs 107, 107a may optionally have different spacing, such as progressively closer spacing, or random spacing. Preferably the ladder 100 can be used with 2 to 11 rungs 107, however more than 12 rungs 107 can also be used.

[0050] With reference to FIGS. 2A and 2B, generally, the rungs 107, 107 are straight but can optionally be curved, or have curved sections. Preferably the rungs 107, 107 can have beveled edges 123 which prevent the user's foot from catching the edges of the rung 107, 107. Optionally, the each rung 107, 107 may include a mounting hole 125 there through. The term mounting hole refers to an opening in the rung 107, 107 whereby a stringing material or rod can be passed through. The mounting hole 125 has a mounting hole diameter 127 and can assist in the storage of the ladder 100 and other components.

[0051] At least one rung 107 on the ladder 100 includes a first clasp 113 located at the first end 111 of the rung 107. The clasp 113 removably attaches the rung 107 to the stile 103. Thus, depending on the desired use of the ladder 100, the rung 107 can be fastened to different locations along the stiles 103, 105. Each first clasp 113 has a closed position 117 and an open position 119. In the closed position 117 the clasp 111 grips the stile 103 and prevents the rung 107 from moving along the stile material. In the open position 119 the clasp 111 is disconnected from the stile 103. In this configuration where the rung 107 only has a first clasp 113 at one rung end 111, the other rung end 109 can be connected to the stile 105 by any means so long as the rung 107 remains movable on the stile 103. In a preferred embodiment, the second rung end 109 has a second clasp 115. This configuration not only allows for the rung 107 to be moved and repositioned along the stiles 103,105 but also allows for the rung 107 to be completely removed from the stiles 103,105.

[0052] FIGS. 2A and 2B illustrate a clasp 113, 115 used in embodiments in the ladder 100. For ease of illustration the first clasp 113 is shown in the closed position 117. The clasp 113 has a top half 129 and a bottom half 131, connected via a hinge 133. In this embodiment, the hinge 133 is a living hinge, formed via a thin section of flexible plastic material. Alternatively, the hinge 133 may be a mechanical hinge, whereby the top half 129 and the bottom half 131 are separate parts, pivotally attached with a pin extending through them. Separate conventional hinges may also be attached to the top half 129 and bottom half 131 via fasteners to provide pivotal attachments. The living hinge 133 advantageously allows for the rung 107 and clasp 113 to be formed or molded as a single part, thereby reducing the cost of manufacture.

[0053] FIG. 2B shows a cross section view of the clasp 113 in the closed position 117. The clasp 113 may include a spring latch 135, which functions to keep the clasp 113 in the closed position. The spring latch 135 comprises a tab 137 and a latch ledge 139. In the closed position 117, the spring latch 135 may engage with a slot 141 and a slot ledge 143. When the tab 137 is pressed by the user, the latch ledge 139 moves past the slot ledge 143, allowing the spring latch 135 to be released from the slot 141, thus the clasp 113 can be placed in the open position 119. The spring latch 135 may have a curved or shape, allowing the spring latch 135 to bend when pressed and then return to shape.

[0054] FIG. 3A illustrates a close up of the clasp 113 in the open position 119, whereby the top half 129 has pivoted about the hinge 133. The top half 129 and bottom half 131, have at least one rib 145 and preferably a plurality of ribs 145. When the clasp 113 is in the closed position 117, the ribs 145 grip the stiles 103, 105, thus preventing the rung 107 from moving along the stiles 103,105. Note that a clasp 113, 115 having the configuration as shown and described-specifically having a closed 117 and open position 119, advantageously allows a user to reposition and secure the rung 107 on the stiles 103, 105 using a single part and without the assistance of a tool.

[0055] FIG. 3B shows a perspective view of the ladder 100 where each rung 107 illustrated has a first and second clasp 113, 115 located at each rung end 109,111. The clasps 113, 115 on the rungs 107 are shown the open position 119. As discussed above, for each rung end 109, 111 to be removed from the stiles 103, 105 the clasps 113, 115 at each rung end 109, 111 are in the open position 119.

[0056] FIG. 4 shows an exploded perspective view of another embodiment of the ladder 100 where each rung 107 is removed from the stiles 103, 105.

[0057] In another embodiment the present invention provide for a hurdle 200 as shown in FIG. 5. The hurdle 200 has an upright position 203 and a collapsed position 205, the hurdle has a crossbar 201 and a pair of legs 207 pivotally connected to the crossbar 205. The cross bar has a top surface 209, a bottom surface 211, a first crossbar end 213, a second crossbar end 215. Each leg 207 has a proximate end 217 and a distal end 219 where the proximate end 217 is pivotally connected to each crossbar end 213, 215. The distal ends 219 are for placement on the surface 101. The legs 207 being pivotally attached to the crossbar 201 allows for the legs 207 to rotate relative to the crossbar 201.

[0058] The distal end 219 may have a base 220 to support and sturdy the hurdle 200 on the exercising surface. The base 200 can have a curved cross section, which may provide minimal friction in relation to the exercising surface 101. Therefore, if the hurdle 200 is accidentally stepped on with force the curved profile of the base 220 allows the leg 207 to slide outwards, until the leg 207 is horizontal with the ground, reducing the likelihood of breakage of the hurdle 200 or injury to the athlete.

[0059] Plastic materials, such as polypropylene may be used to provide lightweight hurdles 200 with sufficient strength and stiffness. However, it is contemplated that the hurdles 200 may be formed using other suitable materials such as metal or rubber or combinations of different materials. Preferably, the length of the leg 207 is between 10 inches to 17 inches, and most preferably 12 to 14 inches.

[0060] When the hurdle 200 is in a collapsed position 205 as shown in FIG. 5B, the legs 207 are pivoted towards the bottom surface 211 of the crossbar 201 to be substantially parallel to the crossbar 201. The distal ends 219 of the legs 207 may include a cutout 221, which is sufficiently wide enough to allow the opposing leg 207 to fit inside the cutout 221 when the hurdle 200 is collapsed, as shown in FIG. 5C. When the hurdle legs 207 are folded flat against the crossbar 205 it creates an efficient package size, as shown in FIG. 5B. The cutout also allows for the hurdle to optionally connect to the rung ends 109, 111 of the ladder 100.

[0061] Another utility of the present invention is illustrated in FIG. 6. The rung 107 of the ladder 100 can advantageously be used as the crossbar 201 of the hurdle 200. When the clasps 113, 115 are in the open position 119, the proximate end 217 of each leg 207 can be attached to each clasp 113, 115.

[0062] FIG. 7 illustrates an exploded view of one example of a connection between the leg 207 and crossbar 201 components. The proximate end 217 of the leg 207 includes a first and second shoulder 223, and a first and second pivot post 225. The second pivot post 225 is a mirror image of the first pivot post 225. The pivot posts 225 are sized appropriately to fit into a hollow end 227 of the crossbar 201. Unlike the rung 107, the crossbar 201 utilized in FIG. 7 does not have a clasp 113, 115 having an open and closed position 119, 117 but rather a single molded crossbar end 213, 215 having an opening to receive the pivot posts 225. In this configuration the shoulders 223 are flexible enough to stretch to accommodate insertion of the pivot posts 225. FIG. 7A illustrates a cross sectional view of the connection shown in FIG. 7. Alternatively, an opposite configuration is also possible. For example, the pivot posts 225 could extend from the crossbar 201 and a hollow end 227 could be positioned on the proximate end 217 of the leg 207. Those skilled in the art will appreciate that there are numerous possibilities to pivotally attach the legs 207 to the crossbar 201 and the examples provided are not intended to be limiting.

[0063] Now referring to FIG. 8 which illustrates when the rung 107 having clasps 113, 115 is used to create a hurdle 201. In this example, the proximate ends 217 of the legs 207 have the same configuration as shown in FIGS. 7 and 7A specifically, a first and second shoulder 223, and a first and second pivot post 225. The second pivot post 225 being a mirror image of the first pivot post 225. Preferably, the shoulders are flexible enough to stretch to receive the pivot posts 225. If the shoulders cannot be flexed, in this configuration the claps 113, 115 can be placed in the open position 119 to receive the pivot posts 225.

[0064] Once the legs 207 are connected as shown in FIG. 7 or FIG. 8, they can pivot about the ends 213, 215 of the crossbar 201 and the hurdle 200 can be alternated between an upright 203 and collapsed 205 positions. The legs 207 can also comprise one or more snap members 231, preferably located on the proximate end 217 which snap into a receiving feature on the crossbar. The snap member 231 aids in the rotation of the legs 207 about the ends 109, 111 of the crossbar 201. The pivot angle 229 between the crossbar 201 and each leg 207 provides for height 242 adjustment of the crossbar 201 relative to the exercising surface 101.

[0065] For ease of illustration only the crossbar 201 leg 207 connection shown in FIG. 8 is shown in FIGS. 8A-8D. FIGS. 8A-8D show cross section views of the crossbar 201 and leg 207 connection when the leg is located in different positions. A snap member 231 may extend perpendicular to the surface of one or more of the shoulders 223. The snap member 231 may have a plurality of grooves 233, of an equivalent size and shape to that of the hinge 133. FIG. 8A shows a leg 207 in the collapsed position 205, which is also shown in FIG. 5B. As shown in FIG. 8B the leg 207 has pivoted about the end 213 of the crossbar 201. As the snap member 231 encounters the hinge 133, the flexible nature of the material allows the snap member 231 to bend out of the way of the hinge 133 and then move back into position, aligning with one of the grooves 233, thereby locking the leg 207 in a first hurdle position 235, at a pivot angle 229 BB in relation to the crossbar 201. As shown in FIG. 8C, the user may apply reasonable force to continue pivoting the leg 207, causing the snap member 231 to bend out of the way for a second time and then move back into position, locating in a second groove 233, thereby locking the leg 207 in a second hurdle position 237, at a pivot angle 229 CC in relation to the rung 201. In the preferred embodiment, there may be two grooves 233, however it is contemplated that there may be fewer grooves 233, resulting in fewer hurdle 200 positions. Likewise, additional angle settings can be achieved by adding further grooves 233 to the snap member 231. As shown in FIG. 8D, the user may apply reasonable force to continue pivoting the leg 207, causing the snap member 231 to bend out of the way and move back into position for a third time, where no grooves 233 are in contact with the hinge 133. As the leg 207 continues to pivot a stop block 239 may be provided to prevent the leg 207 from pivoting further, thereby locking the leg 207 in a third hurdle position 241, at a pivot angle 229 DD in relation to the crossbar 201. In the preferred embodiment, a combination of snap members 231 and stop blocks 239 have been used, however it is contemplated that only snap members or only stop blocks may be used to achieve the same effect. Alternatively, other methods of locking the legs 207 at various angles may be used including but not limited to a removable cotter pin or a spring button.

[0066] FIG. 9 shows a top view of a safety feature 245 of the hurdle 200. If substantial force is applied to the leg 207, for example by a user accidentally stepping on the hurdle 200 during use, the shoulders 223 may be sufficiently flexible enough to bend outward away from the crossbar 201, allowing the stop block 239 to continue to move past the edges of crossbar 201. This feature prevents breakage of the legs 207 or the crossbar 201. Using reasonable force, the user can then rotate the leg 207 in the opposite direction returning the leg 207 to the third hurdle position 241.

[0067] FIG. 10A shows a front view of the hurdle in the first hurdle position 235. As described above the legs 207 are locked at a pivot angle BB. Thus raising the crossbar 201 up to at a height 242 EE from the surface 201. Depending on the length of the legs 207, the height 242 EE preferably ranges from about 10 inches to 20 inches, and more preferably 12 inches. FIG. 10B shows a front view of the hurdle 200 in the second hurdle position 237. As described above the legs 207 are locked at a pivot angle 229 CC, which is more obtuse than angle BB. Thus raising the crossbar 201 up to at a height 242 FF from the surface 101. The height 242 FF preferably ranges from about 7 inches to 13 inches and more preferably about 9 inches from the surface 101. FIG. 10C shows a front view of the hurdle in the third hurdle position 241. As described above the legs 207 are locked at a pivot angle 229 DD, which is more obtuse than angle CC. Thus raising the crossbar 201 up to at a height 242 GG from the surface 101. The height 242 GG preferably ranges from about 4 inches to 8 inches and more preferably about 6 inches from the surface 101.

[0068] When the hurdle 200 is in its upright position 203, the hurdle 200 can be used in various exercises. Optionally, the hurdle can be positioned in close proximity to or above the stiles 103, 105 and rungs 107, 107of the ladder 100. This allows the user to exercise with both the ladder 100 and the hurdles 200. When the rung 107 is used as the crossbar 201 the attachment of legs 207 to rungs 107 can be repeated for the desired number of hurdles 200. The user can then elect to use the rungs 103 in a position close to the surface 101 or in an upright position 205 as a hurdle 200. The hurdles 200 do not have to be connected to the ladder rungs 107, 107 or even in close proximity to the ladder 100. Depending on the exercise, the user may use the hurdles 200 in a different capacity. For example, if the ladder 100 comprises 10 rungs 107,107 the user may elect to have 5 rungs 107,107 spaced apart on the stiles 103, 105. The other 5 rungs 107 may be used to make 5 hurdles 200. The user could then create an obstacle course where the 5 rungs are hopped over doing a side step and then the hurdles 200 are individually jumped after the ladder exercise is completed.

[0069] FIGS. 11 and 12 show a storage method. A hanger 300 has a diameter 301 that is less than the diameter of the mounting hole diameter 125. For example, the hanger 300 may include a rod end 303 and a hook end 305, The rod end 303 is inserted through the mounting hole 125 on each rung 107,107, thereby retaining all the rungs 107, 107 and preventing tangling during storage. Hurdles 200 can also be stored on a hanger 300. Each hurdle 200 can have an optional mounting hole 125 so that both the ladder 100 and hurdles 200 can be stored on the hanger 300. In a configuration that includes legs 207, the legs can also have an optional mounting hole 125.

[0070] The hanger 300 may have a tightly curved U shape and be made of a springy material, such as steel wire or plastic. The hook end 305 may have a hooked or U shape, allowing for the rod end 303 to be closed and retained inside the hook end 305, and held in place by the spring force of the material, thereby preventing the rungs 107, 107 or other components from sliding off the hanger 300. The hanger 300 may optionally include a handle 307, which can be used for transporting the ladder 100, legs 207 and hurdles 200.

[0071] FIG. 13 shows a protective cover 400 for the ladder or the hurdles. The components may be stored in a cover 400, which extends over the rungs 107, 107, legs 207, and hurdles 200. The cover 400 is closed by means of a fastener 402 below the curved handle 307 of the hanger 300, allowing the ladder 100, legs 207 and hurdles 200 to be protected during transport and storage. The fastener 402 may be hook and loop material, a snap, magnet or any other closing mechanism.

[0072] In use the ladder 100 is removed from the optional cover 400. The hanger 300 is unlocked and components of the ladder system are removed from the hanger 300. The stiles 103, 105 of the ladder 100 are placed on the exercising surface 101 in an extended position as shown in FIG. 1. The rungs 107, 107 can be repositioned along the stiles 103, 105. Rungs 107 having the clasps 113, 115 can be opened so the rung 107 can be moved along the stiles 103, 105. When the rung 107 is in the desired location the clasps 113, 115 are locked in a closed position thereby securing the rung 107 to the stiles 103,105. This step can be repeated until all of the rungs are in the desired location for the exercise.

[0073] Similarly, a hurdle 200 can be removed from a cover 400 and taken off a hanger 300. If the hurdle 200 was stored in the collapsed position 205 the legs 207 are rotated away from the bottom surface of the crossbar 201, placing the distal ends 219 of the legs 207 on the exercising surface 201. The height of the crossbar 201 can be adjusted by changing the pivot angle 229 BB, CC, DD. The user can select the number of hurdles 200 for the desired exercise. The hurdle 200 can optionally be in connection with the ladder 100 or even connected to the rungs 107, 107 by inserting the cutout 221 in the rung ends 109, 111.

[0074] In the preferred embodiment, a user can simply remove a rung 107 from the stiles, attach a leg 207 to each rung end 109, 111 and pivotally rotate the legs 207 so that the distal end 219 is placed on the exercising surface 201. Once finished, the user moves the hurdles 200 in the collapsed position 205 by rotating the legs 207 toward the bottom surface of the rung 107 or crossbar 201 so the legs 207 are substantially parallel to the crossbar 201. The stiles 107, 107 of the ladder 100, can be folded by stacking the rungs 107, 107 in a compact arrangement. Optionally, the user can unlock the hanger 300 and insert the rod end 303 through each mounting hole 125 and package the system with a protective cover 400.
