发明名称 Athlete{3 s long jump pit
摘要 A portable long jump pit is disclosed which may be installed in a gymnasium, on top of a regular playing surface and used in conjunction with an elevated runway, or outdoors recessed into the ground surface such that the top is level with a runway. The pit includes a foam cushioning member which is held stationary relative the runway and a separate fabric cover over the cushioning member which is held in place by elastic cords. When the long jumper lands on this fabric member, it moves laterally on the top of the cushioning member, the elastic supports and the cushioning member absorbing the lateral momentum of the athlete. An optional enlarged landing pillow or bumper is placed at the end of the pit opposite the runway to protect the athlete from running beyond the pit surface after his jump. Numerous marking systems are disclosed for recording the landing position of the athlete.
