Abstract

Abstract A jumping pit of the portable type for use in conjunction with pole vault and high jump events. First, second and third modules are positioned adjacent each other and have a main cover secured thereto and extending thereover. Each of the modules comprise a lower foam section having an upper foam section secured thereto. The lower foam section is provided with a plurality of spaced apart vertical openings extending therethrough and is constructed of a foam material which is more firm than the upper foam section. A module cover encloses the foam sections and has a loosely woven top provided thereon. The main cover also has a loosely woven top portion, the tops of the covers permitting air to escape from the foam sections upon the jumper falling thereon. An auxiliary module having a cover thereon may be secured to the front end of the modules when the pit is being used for pole vaulting. A flap extends from the main cover over a portion of the auxiliary module and is secured thereto.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 289 words
A jumping pit, comprising, a plurality of resilient modules arranged in a side-by-side relationship, each of said modules comprising a resilient body member and a module cover enclosing the same, each of said body members comprising a lower rectangular foam section and an upper rectangular foam section positioned thereon, said lower section having a plurality of vertically disposed openings formed therein and extending completely therethrough, said upper rectangular foam section being positioned immediately adjacent said lower rectangular foam section, and a cover means at least partially enclosing said plurality of modules and being secured thereto to prevent the separation of said modules with respect to each other, a resilient auxiliary module secured to said plurality of modules and extends from one side thereof, said auxiliary module having a length less than the distance between the bar supports of a pole vault apparatus, said auxiliary module having a recessed area at its center length to permit said auxiliary module to partially extend around the vaulting box, said auxiliary module having a tapered upper end portion which extends downwardly and outwardly from the plurality of modules; and a flap member extending from said cover means partially over said upper end portion of said auxiliary module, said flap member being normally secured To said auxiliary module, said flap member also being able to be positioned in a vertically disposed condition adjacent said one side of said plurality of modules when the auxiliary module is not secured to said plurality of modules when the pit is being used for high jump events, and a plurality of resilient members detachably securing said flap member to said auxiliary module when the said auxiliary module is positioned at said one side of said plurality of modules.
Claim 2
Dependent Claim 289 words
A jumping pit, comprising, a plurality of resilient modules arranged in a side-by-side relationship, each of said modules comprising a resilient body member and a module cover enclosing the same, each of said body members comprising a lower rectangular foam section and an upper rectangular foam section positioned thereon, said lower section having a plurality of vertically disposed openings formed therein and extending completely therethrough, said upper rectangular foam section being positioned immediately adjacent said lower rectangular foam section, and a cover means at least partially enclosing said plurality of modules and being secured thereto to prevent the separation of said modules with respect to each other, a resilient auxiliary module secured to said plurality of modules and extends from one side thereof, said auxiliary module having a length less than the distance between the bar supports of a pole vault apparatus, said auxiliary module having a recessed area at its center length to permit said auxiliary module to partially extend around the vaulting box, said auxiliary module having a tapered upper end portion which extends downwardly and outwardly from the plurality of modules; and a flap member extending from said cover means partially over said upper end portion of said auxiliary module, said flap member being normally secured To said auxiliary module, said flap member also being able to be positioned in a vertically disposed condition adjacent said one side of said plurality of modules when the auxiliary module is not secured to said plurality of modules when the pit is being used for high jump events, and a plurality of resilient members detachably securing said flap member to said auxiliary module when the said auxiliary module is positioned at said one side of said plurality of modules.
