TECHNICAL FIELD

The present invention relates to a hurdle used primarily for athletic events, athletic training, and the like.

BACKGROUND OF THE INVENTION

Hurdles are used in a wide variety of athletic events. For example, some track and field events include placing a series of spaced apart hurdles along a running track. Athletes must cross over the hurdles while competing with each other in a race. These types of hurdles are usually several feet high, and the various athletic organizations have adopted defined heights for the hurdles for a specific racing event, league, or competition.

Similarly, hurdles are also used for training purposes. An athlete positions one or more hurdles along a path and perform training drills that usually include crossing over each hurdle. Training hurdles are usually positioned low to the ground as shown in the attached FIGS. 1A (PRIOR ART) and 1B (PRIOR ART). Common heights for these types of hurdles are between 6 inches to 12 inches from the ground.

It is desirable for hurdles to be economical to manufacture and purchase, portable, easy and compact to store when not in use, easy to set-up and use, easily height adjustable, and easily deflected if contacted during use while remaining stable in wind and the like. To date, known hurdle structures have had limited success with optimizing these desirable characteristics.

BRIEF SUMMARY OF THE INVENTION

The present invention is a portable hurdle that optimizes these desirable characteristics. It is economical to manufacturer and purchase, stores compactly and easily, sets up quickly and easily, can be adjusted to provide a plurality of hurdle heights, remains stable during use even in wind, but collapses easily if inadvertently contacted by the athlete during use.

In disclosed embodiments, the hurdle is formed of a base portion and a bow portion. The bow portion is brought into tension and held in place with a securing device, such as a strap or the like, to form the legs of the hurdle. In one disclosed embodiment, the strap forms the top of the hurdle. In other disclosed embodiments, the base defines the top of the hurdle.

The length of the strap can be adjusted to provide an adjustable height hurdle. In a preferred embodiment, the strap has predefined attachment points so as to set the height of the hurdle to corresponding standard hurdle heights. Alternatively, the strap can be infinitely adjustable, thereby providing an infinitely adjustable height as needed.

In addition to other benefits disclosed herein, the present invention fulfills these needs.

DETAILED DESCRIPTION OF THE INVENTION

A first preferred hurdle structure 20a is disclosed in FIGS. 2-7. The base portion 24 is integrally formed with the bow portion 26, thereby defining a monolithic structure. Preferably, the monolithic structure is substantially planar when the bow portion 26 is in its neutral, non-tensioned, configuration 29 shown in FIG. 2.

The base portion 24 can straddle the bow portion 26′ as shown in FIGS. 1-7, or the base portion 24 can be centered between the bow portion 26 as shown in FIG. 8.

The hurdle structure 20a of this embodiment is set up by extending the securing device 28, which is preferably a strap or the like, between the ends 40a, 40b of the bow portion 26 in its neutral position 49 (FIG. 3) and moving the ends 40a, 40b of the bow portion towards each other, thereby placing the bow portion 26 in tension as best shown in FIGS. 1 and 4. The securing device 28 is operably secured toward the ends 40a, 40b of the bow portion 26, thereby holding the bow portion 26 in the desired tension position.

Preferably, a plurality of spaced apart attachment structures 30 for operably securing the securing device 28 to the bow portion 26, such as snaps or the like, are positioned along one end 31 of the securing device 28. Accordingly, the height 27 of the hurdle 20 can preferably be adjusted at least between a low position 50 (shown in FIG. 1) and a high position 52 (show in FIG. 4) simply by securing the ends 40a, 40b of the bow portion 26 to different spaced-apart attachment structures 30. For example, the spaced-apart attachment structures can be aligned so as to allow the height 27 of the hurdle to be 6 inches, 8 inches, and 12 inches depending on which attachment structure 30 is connected by the user. Of course, the hurdle 20 can be sized so as to provide other heights 27 including those used in conventional track and field events and the like.

Preferably, the base portion 24 is folded along its longitudinal length to define fold lines 55a, 55b as best shown in FIG. 4 to in increase rigidity and support.

Referring to FIGS. 9-14, alternative preferred hurdle structures 20b-e are disclosed. In order to prevent undue repetition, like element numbers between the embodiments are like numbered.

Referring to the hurdle 20b embodiment shown in FIG. 9, the base portion 24 is an elongate substantially rigid member and the bow portion 26 includes left and right bow members 26a, 26b, respectively spaced apart from each other and extending there from. The bow members 26a, 26b are preferably substantially planar, operably secured to the base portion 24 so as to assume a substantially neutral position when not in tension aligned substantially along the longitudinal centerline of the base portion 24, and have substantially flat distal edges 57a, 57b.

A user places the bow members 26a, 26b in tension by moving the distal ends 40a, 40b, respectively, of each bow member 26a, 26b toward each other. A securing device 28 that preferably includes a plurality of spaced-apart attachment structures 30 there along operably holds the bow members 26a, 26b in tension. Preferably, the securing device 28 is a strap that extends between and is operably secured toward the distal ends 40a, 40b of the left and right bow members 26a, 26b. The distal edges 57a, 57b of the bow members 26a, 26b, rest on the ground while the base portion 24 is elevated substantially horizontally above the ground at a desired height 27 as shown in FIG. 9.

In FIGS. 10 & 11, the hurdle 20c and hurdle 20d are substantially similar in construction as hurdle 20b (FIG. 9). However, in order to prevent the securing device 28 from being stepped on during use, the securing device is slidably received through a lower side of the base portion 24 of hurdle 20c as shown in FIG. 10. Alternatively, hurdle 20d has two straps 28a, 28b operably extending between the distal ends of the bow member to the base portion as shown in FIG. 11.

The base portion 24, left bow member 26a, and right bow member 26b can be individual components that are secured together with conventional means and methods. Alternatively, these structures can be integrally formed from a monolithic structure, such as by molding, cutting, forming and the like. In such case, the base portion 24 preferably includes rigidity structures therein, like elongate seams, folds, and the like.

An alternative hurdle 20e embodiment 20e is shown in FIGS. 12-14. In this embodiment, the hurdle 20e is preferably formed of a monolithic, substantially planar material shown in FIGS. 12 and 13 to define a substantially planar H-shape when in its neutral position shown in FIG. 13. The center of the H defines the base portion 24 with the left and right arms of the H each being a bow portion 26 thereby defining left and right bow portions 26a, 26b, respectively, on each bow portion 26. Left and right securing devices 28a, 28b operably hold the respective left and right bow portions in tension, thereby raising the base portion 24 to the desired hurdle height 27 for use.

Preferably, each securing device includes a plurality of spaced apart attachment structures 30 thereby allowing the height of the hurdle to be adjusted.

It can be appreciated that each hurdle can be stored and transported relatively easily simply by detaching the securing devices from their respective bow portions. This causes the tension in the bow portions to be released so that they return to their substantially neutral, planar, position. Accordingly, the hurdles become substantially planar and can be stacked, stored, and carried easily.

To use the hurdles, the user simply attaches securing devices so as to place the bow portions in tension as described. He or she then positions the hurdles as desired and uses them like conventional hurdles.

Having described and illustrated the principles of our invention with reference to a preferred embodiment thereof, it will be apparent that the invention can be modified in arrangement and detail without departing from such principles. For example, although the preferred disclosed securing device has a plurality of spaced apart attachment structures, an alternative attachment structure, such as a slider and clamp, could be used to make the hurdle height infinitely adjustable. Accordingly, in view of the many possible embodiments to which the principles may be put, it should be recognized that the detailed embodiments are illustrative only and should not be taken as limiting the scope of our invention. Accordingly, we claim as our invention all such modifications as may come within the scope and spirit of the following claims and equivalents thereto.
