Abstract: A form for constructing a thrower's circle includes a pair of half sections. Each half section has an upper surface and a base surface and two full length members and two half length members. The full length members and the half length members are connected together substantially at right angles to form a rectangle with four corners. A corner brace is located in each of the four corners. An inside cross member and an outside cross member extend between the half length members and are generally parallel to the full length members. A pair of semi-circles, each having substantially the same diameter that is larger than the length of the half length members and less than the length of the full length members. Means are provided for securing the half sections together so that the semi-circles form a full circle. Tubes extend from the circle toward the base to drain water from with in the circle.

Abstract: A method for installing a thrower's circle in the ground of an athletic field includes assembling a form for constructing a thrower's circle dimensioned for a player throwing at least one of a hammer, a shot put, and a discus from a plurality of sections having mounted thereto a plurality of arcuate portions. When the plurality of sections are assembled together, the plurality of arcuate sections together form a full circle, and wherein a portion of the plurality of sections is disposed outside the full circle and a portion of the plurality of sections is disposed inside the full circle. The method further includes excavating the ground, placing the assembled form in the excavated ground, placing cement in the assembled form, and allowing the cement to dry.

Abstract: A temperature compensating outdoor wall padding apparatus in one embodiment incorporates a stretch fabric into the edges of a vinyl cover to provide a tension on the vinyl cover minimizing the possibility of wrinkling of the vinyl cover due to a change in temperature. In another embodiment, the temperature compensating outdoor wall padding apparatus may employ a resilient cover, stretchable in 4 directions and pre-tensioned to provide tension on the resilient cover minimizing the possibility of wrinkling of the resilient cover due to a change in temperature. Methods for forming the same are also disclosed.

Abstract: A take-off board system for a triple or long jump generally includes an elongated frame, an elongated take-off board, and a track material member. The frame includes inwardly-extending flanges defining a chamber therein. The take-off board includes a first portion slidably receivable in the chamber of the frame, and a second portion defining an outer take-off surface. The track material member is disposed on an outer surface of the frame. The take-off board system is disposable in a first position in a cavity in the ground with the outer take-off surface of the take-off board disposed even with a track surface, and the take-off board assembly is disposable in a second position in the cavity in the ground with an outer surface of the track material member disposed even with the track surface.
