This application is a non-provisional filing of U.S. Provisional Application No. 62/553,290 filed Sep. 1, 2017, the contents of which are hereby incorporated by reference herein.
The present invention relates to a protective barrier cage system for use in track and field events such as hammer and/or discus throwing.
Track and field events such as hammer throw and discus throw involve athletes rapidly gaining momentum and using it to throw weighted objects (i.e., a hammer or discus) across distances. As a high level of skill is required for precise release of the objects towards an intended target, accidental releases in unintended directions are not uncommon. As a result, protective barriers are typically employed during said events to contain misthrown objects and prevent spectator injury.
Existing protective barriers typically employ systems of large posts and fences which, while durable, tend to significantly obstruct the spectators' views of the competing athlete inside as a trade-off for providing a structure that will not easily fail. Accordingly, there exists a need for an improved protective track and field barrier system that can provide high spectator visibility of a competing athlete while maintaining structural integrity.

Having thus described embodiments of the invention in general terms, reference will now be made to the accompanying drawings, wherein:
Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. In the drawings, like reference characters and numbers refer to like elements throughout. Also, the drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the disclosure. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein.
It should be understood that “operatively coupled,” when used herein, means that the components may be formed integrally with each other, or may be formed separately and coupled together. Furthermore, “operatively coupled” means that the components may be formed directly to each other, or to each other with one or more components located between the components that are operatively coupled together. Furthermore, “operatively coupled” may mean that the components are detachable from each other, or that they are permanently coupled together.
Embodiments of the present invention are directed to a protective barrier system for track and field events that safely contain misthrown projectiles (e.g., hammers and discus) with little to no damage to the structural integrity of the protective barrier while allowing for high visibility of an interior of the protective barrier by spectators observing from the exterior. The invention comprises a series of support members supporting a frame from which a barrier material (e.g., a net) may be suspended to define an enclosure. Cables act as a series of virtual posts which provide structural support and shape to the barrier material to prevent contact of the barrier material against the support members upon a stray projectile (e.g., a hammer or discus) striking the interior of the barrier. In this way, damage to the barrier material may be prevented and visibility of the interior event increased.
A “user,” as used herein may refer to a beneficiary of the protective qualities of the protective barrier system. In some embodiments, the user may be an athlete competing in a track and field event (e.g., hammer throw or discus throw) who is contained within an interior enclosure of the protective barrier system. In some embodiments, the user may be a spectator positioned on the exterior of the protective barrier system who is observing another user, such as an athlete, compete within the interior of the protective barrier system. In some embodiments, the protective barrier system is for use in track and field events. In a specific example, the protective barrier system is a hammer and/or discus cage.
In the illustrated embodiment, first 102 and second 104 forked support members and the first 106 and second 108 single support members are positioned to form and support a curvilinear shape of the frame 111 with the attached barrier material 110, wherein the first 106 and second 108 single support members help define a curvature of a formed enclosure, while the first 102 and second 104 forked support members form doors positioned relative to the enclosure that are configured of at least partially closing off an opening of the enclosure. In a specific embodiment, the enclosure formed by the frame 111 and barrier material 110 is U-shaped, however, in other embodiments, one or more support members may be positioned to form alternative shapes having different (
In the illustrated embodiment, the frame 111 comprises an upper portion 112 and a lower portion 114 which function as support bands for the barrier material 110. The barrier material 110 is operatively coupled to and suspended between the upper and lower portions 112, 114 of the frame 111 to form walls of the enclosure. The upper and lower portions 112, 114 are rigid or semi-flexible frames which provide shape and structure to the walls of the enclosure formed by the barrier material 110. The upper portion 112 is coupled to and suspended from upper ends of the support member 102, 104, 106, 108. The lower portion 114 is coupled to a base of the support members 102, 104, 106, 108 adjacent the surface. In one embodiment, the lower portion 114 is spaced from the surface. The lower portion 114 is configured to weights down a bottom end of the attached barrier material 110 and reduce undesired movement of the barrier material 110 (e.g., from wind) and retain a desire shape of the enclosure. In some embodiments, the support bands are lightweight, hollow channels or tubular members. In the illustrated embodiment, the upper and lower portions 112, 114 of the frame 11 have a square or rectangular cross section. In other embodiments, the support bands have a different cross sectional shape (e.g., a circle, triangle, S-shape, or the like). The frame 111 may be constructed from metal, plastics, composite materials, and/or combinations thereof.
In one embodiment, the frame 111 further comprises a plurality of vertical cables 115 extending between the upper portion 112 and the lower portion 114 and positioned adjacent the barrier material 110 on an exterior side of the enclosure. The plurality of vertical cables, along with the upper and lower portions 112, 114 provide shape and structure to the enclosure while acting as virtual posts which are described in detail below.
As illustrated in
As previously discussed, a barrier material 110 is suspended from the frame 111 of the protective barrier system 100 to define an enclosure having an interior and an exterior. The suspended barrier material 110 is suspended at least somewhat vertically to form a continuous wall around an interior of the enclosure. In some embodiments, the barrier material 110 is a net, fence, or similar open-meshed fabric or material constructed from a polymer, metal, and/or other material that may be twisted, knotted, woven, or bonded together at regular intervals that may allow for an observer or spectator positioned on the exterior of the enclosure to at least partially view the interior of the enclosure through the barrier material 110. The barrier material 110 may comprise a material having a high stress and/or strain resistance that can withstand multiple impacts from weighted objects (e.g., a hammer or discus) while maintaining structural integrity and shape. In some embodiments, the barrier material 110 may be a net comprising a material having a minimized diameter that maximizes visibility of the interior of the protective barrier for one or more spectators on the exterior of the protective barrier. In a specific embodiment, the barrier material 110 is constructed from ultra-high molecular weight polyethylene (UHWPE).
As illustrated in
In the illustrated embodiment, a second eyelet 308 is used to operatively couple the curved extension 300 to the base 208 of the same forked support member 200 via a vertical cable 310 or the like. The vertical cable 310 is typically positioned on an exterior side or in-line with the barrier material 110 to provide structure, shape, and support to the barrier material while further preventing the barrier material 110 from coming into contact with the various support members when the barrier material 110 is struck back by the force of an object contacting the interior of the enclosure. The barrier material 110 may degrade, fail, or rupture due to excessive contact with a rigid, solid object such as the support members thereby reducing the protective effectiveness of the protective barrier system 100. The vertical cable 310 may be tensioned using a tensioning tool or the like to provide additional structure and resistive capacity to the walls of the enclosure. In this way, the vertical cable 310 acts as a virtual post for the protective barrier system 100 in that the vertical cable 310 provides structure and shape to the walls of the barrier, while remaining flexible and not providing a point of contact for which the barrier material 110 may strike contact the support members. Additionally, the virtual posts do not excessively obstruct the view of the interior of the enclosure to the extent that a traditional post would, thereby allowing for increased visibility of a user within the enclosure. In the illustrated embodiment, the barrier material 110 is supported by a plurality of virtual posts where thicker, more rigid metal posts or beams might be typically placed. Furthermore the greater flexibility of the virtual posts when compared to traditional post constructions allows for an impact force experienced from an object striking the enclosure to be spread out over the surface area of the barrier material 110. Additionally, the more flexible virtual posts allow for the construction of smooth, continuous shapes for the enclosure than allowed by traditional post systems.
In one embodiment, a third eyelet 312 (as seen in
As illustrated in
The vertical post 206 additionally has a rear eyelet 424 (as seen in
A second eyelet 606 may be used to operatively couple the upper portion of the single curved extension 502 to the base of the single support member 500 via a vertical cable 508 or the like. The vertical cable 508 is positioned behind or in line with the barrier material 110 to provide structure, shape, and support for the barrier material and prevent the barrier material 110 from coming into contact with the various support members upon the barrier material 110 being struck back by the force of a contacting object. The vertical cable 608 may be tensioned using a tensioner, puller, or the like to provide additional structure to the walls of the protective barrier system. In this way, the vertical cable 608 acts as a virtual post for the protective barrier system. As the single support member 500 is positioned where a horizontal component of the direction of extension of the curved extension 502 is perpendicular to the surface of the barrier material 110, a second vertical cable is not necessarily required to sufficiently protect the barrier material 110. In an alternative embodiment, a second vertical cable may be used as a secondary virtual cable to further protect the barrier material 110 from contact with the support member 500.
In a specific embodiment of the invention, an approximate length, width, and height of the assembled protective barrier system 100 is approximately 13 meters, 7.5 meters, and 9 meters respectively, wherein the floating hinges 406 of the first and second forked support members 102, 104 are spaced approximately 7.5 meters apart and the distance from the floating hinge 406 of the first forked support member 102 to the base 504 of the first single support member 106 is approximately 8.5 m.
Referring now to
As illustrated in the alternative embodiment, cable 311 is used to operatively couple frame 111 to the forked support member 200. Cable 311 is fed through pulley system 304 to operatively couple the upper portion 112 of the frame 111 to an end of the curved extension 204 via eyelets 302 and 306. Cable 311 is then attached to the triangular frame 404 of the base 208 at a cable attachment point 1210. In the illustrated embodiment, the cable attachment point 1210 comprises a structure configured for winding and collecting an excess length of the cable 311 following tensioning of the cable 311. Similar to cable 311 of forked support member 200, cable 509 of the single support member 500 may similarly be configured to travel through pulley system 604 to operatively couple the frame 111 to the single support member 500, wherein the cable 509 is attached to the base 504 at a similar cable attachment point.
The portions of the cables 311 and 509 extending down from pulley systems 304 and 604, respectively, may be employed as secondary virtual posts and provide further protection for preventing contact between the barrier material 110 and the support members 200, 500. It should be noted that even though vertical cable 314 is depicted in
