A sports training ladder, often referred to as an “agility ladder” is commonly used by athletes to improve speed, balance and/or agility. Agility ladders generally have several spaced apart rungs attached to left and right stiles. In use, the agility ladder is placed on the ground, with open foot spaces formed between the rungs and stile. The athlete runs, hops or jumps through the agility ladder, with the athlete's feet landing in the foot spaces. Different training exercises may use different patterns of steps, jumps, or hops.
Some agility ladders have fixed rung distances, meaning that the separation distance between each rung cannot be altered by the user. Other agility ladders have movable rungs which are generally not easy to reposition or lock on the stiles. Some agility ladders can also become easily twisted if not stored properly, causing the user to spend considerable time untangling the ladder before use.
Hurdles are individual raised barriers also used in athletic training. Generally, hurdles are spaced several strides apart, with the athlete running and jumping over each hurdle. Some hurdles have a fixed height of typically 6 inches, 9 inches and 12 inches, which limits use of the hurdles. Other hurdles can be adjusted to variable heights, but are often expensive and/or can become easily damaged if stepped on.
Hurdles and agility ladders are frequently used by teams and coaches and the equipment may be bulky, heavy and difficult to carry and/or store. Obtaining the benefits of both an agility ladder and hurdles requires both sets of equipment to be carried to the training location and then set up.
Therefore, there is a need for an improved agility ladder and hurdles that are conveniently adjustable, user friendly, and easy to transport.
A sports training ladder and hurdle of the present invention will address these issues. The present invention provides for adjustable ladders, hurdles and methods of using the same. Optionally, the hurdles can be constructed from the adjustable rungs of the ladder. The present invention also describes advantageous storage and carrying options for storing the ladder and hurdle components.
In particular the present invention provides for a training ladder for use on a surface. The ladder comprises flexible opposed first and second substantially parallel stiles, at least two spaced apart rungs between the stiles and supported by the stiles, each rung having a first and a second end for connection to each of the stiles; and at least one rung having a first clasp in a closed position securing the first end of the rung to the first stile and a second clasp in a closed position securing the second end of the rung to the second stile, where in the closed position the rung with the clasps cannot be moved along the stiles, each clasp having an open position to reposition the rung on the stiles or to remove the rung from the stiles, wherein the ladder is on the surface with the rungs spaced apart for exercise.
In a preferred embodiment each rung has at least one clasp. When each rung has a clasp that affords two positions—open and closed, all of all rungs can be repositioned along the stile and locked in a preferred location. In a most preferred embodiment, each rung has a second clasp. The second clasp like the first clasp has an open and closed position and is located at the end of the rung. By having a clasp at each end of the rung, the rung can be completely removed from the stiles with ease. This is preferable because it allows the user to select the number of rungs for a particular exercise, in addition to altering the number of rungs on the stiles, when the rung is completely removed it can also be used as a crossbar for a hurdle.
In yet another embodiment, the rung optionally comprises a mounting hole there through, where the mounting hole has a diameter. The mounting hole is necessary when the system further comprises a hanger, where the hanger has a diameter. The diameter of the hanger is less than the diameter of the mounting hole on the rung so the hanger can be inserted through the mounting holes for mounting the rungs on the hanger. By hanging the rungs on a hanger, the ladder can be easily stored without becoming tangled. To protect the ladder in transport and storage an optional cover can be used.
In another embodiment the present invention provides for a hurdle. The hurdle having an upright position and a collapsed position, the hurdle comprises a crossbar and a pair of legs pivotally connected to the crossbar. The crossbar has a top surface, a bottom surface, a first crossbar end, and a second crossbar end. Each leg has a proximate end and a distal end where the proximate end is pivotally connected to the crossbar end and the distal end is for placement on an exercising surface. The hurdles are configured such that the distal ends of the legs can be rotated away from the bottom surface of the crossbar in an expanded upright position. When the hurdle is in an upright position it provides height relative to the exercise surface. The height of the crossbar is adjusted by a pivot angle between the crossbar and legs. When the hurdle is in a collapsed position the legs are substantially parallel to the crossbar. Similarly to the rungs, the hurdles can optionally comprise a mounting hole there through. The mounting hole is used to insert a hanger, where the diameter of the hanger is less than that of the mounting hole and can be used for transporting and storing the hurdles.
In another embodiment is a system comprising a ladder and at least one hurdle. The hurdle can be used in close proximity to the ladder or even removably connected to the ladder. In its upright position the crossbar may be over at least part of the ladder, wherein in the collapsed position the legs are pivoted to be substantially parallel to the crossbar. Optionally, the rung of the ladder can function as the crossbar of the hurdle. In this configuration only a pair of legs is required to create a hurdle. If the system comprises the optional legs, then the legs can also have a mounting hole there through to also be stored on the hanger.
In yet another embodiment is a method of using a ladder. The method comprises selecting a ladder having flexible opposed first and second substantially parallel stiles, at least two spaced apart rungs between the stiles and connected to the stiles, each rung having a first and a second end for connection to each of the stiles; and at least one rung having a first clasp in a closed position securing the first end of the rung to the first stile and a second clasp in a closed position securing the second end of the rung to the second stile, where in the closed position the rung with the clasps cannot be moved along the stiles, each clasp having an open position to reposition the rung on the stiles or to remove the rung from the stiles. The user places the ladder on a surface and repositions at least one rung on the stiles by opening the clasps, moving the rung and closing the clasps. The user then performs exercises with the ladder.
In still another embodiment is a method of using a hurdle. The method comprises selecting a hurdle having a crossbar and a pair of legs pivotally connected to the crossbar. The crossbar has a top surface, a bottom surface, a first crossbar end, and a second crossbar end. Each leg has a proximate end and a distal end where the proximate end is pivotally connected to the crossbar end and the distal end is for placement on an exercising surface. In use, the user rotates the distal ends of the legs away from the bottom surface of the crossbar expanding the hurdle in an upright position. When the hurdle is in an upright position it provides height relative to the exercise surface. Optionally, the user can adjust the height of the crossbar by further pivoting the legs away from the bottom surface of the crossbar, thereby increasing the pivot angle between the crossbar and legs. Optionally, the user can adjust the height of the crossbar by decreasing the pivot angle. The user can then perform exercises by jumping over the hurdle. Post use, to collapse the hurdle, the user rotates the distal ends of the legs towards the bottom surface of the hurdle. Once the legs are substantially parallel to the crossbar, the hurdle is in a collapsed position. In the collapsed position the hurdle can be easier to transport and store.
In still another embodiment is a method of using the ladder and system described herein. The method comprises the steps of selecting a ladder having flexible opposed first and second substantially parallel stiles, at least two spaced apart rungs between the stiles and connected to the stiles, each rung having a first and a second end for connection to each of the stiles; and at least one rung having a first clasp in a closed position securing the first end of the rung to the first stile and a second clasp in a closed position securing the second end of the rung to the second stile, where in the closed position the rung with the clasps cannot be moved along the stiles, each clasp having an open position to reposition the rung on the stiles or to remove the rung from the stiles. The user places the ladder on a surface and repositions at least one rung on the stiles by opening the clasps, moving the rung and closing the clasps. Next, the user selects a hurdle that has an upright position and a collapsed position, the hurdle comprises a crossbar and a pair of legs pivotally connected to the crossbar, wherein in the collapsed position the legs are pivoted to be substantially parallel to the crossbar. The hurdle is positioned in in its upright position with the crossbar over the at least part of the ladder and the user performing exercises with the ladder, and jumping over the hurdle. It should be noted that the hurdles do not have to be used in connection with the ladder when exercises are being performed. The hurdles can also be used separately from the ladder.
In another embodiment is a method of using a ladder system. The method comprises the steps of selecting a ladder having flexible opposed first and second substantially parallel stiles, at least two spaced apart rungs between the stiles and connected to the stiles, each rung having a first and a second end for connection to each of the stiles; and at least one rung having a first clasp in a closed position securing the first end of the rung to the first stile and a second clasp in a closed position securing the second end of the rung to the second stile, where in the closed position the rung with the clasps cannot be moved along the stiles, each clasp having an open position to reposition the rung on the stiles or to remove the rung from the stiles. The user places the ladder on a surface and removes the rung with the clasps from the stiles by opening each clasp. The user then secures a leg to each clasp of the removed rung, each leg has a proximate end and a distal end where the proximate end of the leg is pivotally connected to the clasp and the distal end is placed on the surface. The user then performs exercises with the ladder and jumps over the hurdle.
In another embodiment the present invention provides for a kit. The kit comprises a ladder described above and at least one hurdle having an upright position and a collapsed position, the hurdle comprising a crossbar and a pair of legs pivotally connected to the crossbar, the hurdle in its upright position with the crossbar over the at least part of the ladder, wherein in the collapsed position the legs are pivoted to be substantially parallel to the crossbar. Optionally, the ladder and hurdle can be packaged together.
In still another embodiment the present invention provides for a kit comprising a ladder described above and a pair of legs, each leg having a proximate end and a distal end where the proximate ends of the legs are pivotally connected to the rung with the clasps creating a hurdle, the hurdle in an upright position when the distal ends are placed on the surface and when the distal ends are pivoted to be substantially parallel to the rung the hurdle is in a collapsed position. The ladder and legs can optionally be packaged together.

Turning now in detail to the drawings, as shown in
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.
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.
The ladder shown in
With reference to
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.
In another embodiment the present invention provide for a hurdle 200 as shown in
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.
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.
When the hurdle 200 is in a collapsed position 205 as shown in
Another utility of the present invention is illustrated in
Now referring to
Once the legs 207 are connected as shown in
For ease of illustration only the crossbar 201″ leg 207 connection shown in
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, 107′of 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.
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.
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
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.
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.
Thus, a novel training ladder, hurdle and methods of using the same have been shown and described. While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
Although the present invention has been discussed in considerable detail with reference to certain preferred embodiments, other embodiments are possible. Therefore, the scope of the appended claims should not be limited to the description of preferred embodiments contained in this disclosure. It should be emphasized that while the present invention is discussed principally herein in the context of an agility ladder with or without hurdles.
