Physical and mental development jump set

机译:身心发展跳跃集

摘要

A set of jumps comprising a plurality of horizontal elongated jump barriers disposed in generally parallel laterally spaced and aligned position is provided. The opposite end portions of the jump barriers include depending support legs and the upper ends of the support legs are removably telescoped into downwardly opening sockets at the opposite ends of the barriers. The lower ends of the legs are curved and merge smoothly into horizontally directed integral foot portions for support of the legs from a horizontal surface. The legs comprise tubular members and the effective vertical extent of the legs of at least one of the jump barriers differs from the effective vertical extent of the legs of at least one other jump barrier. Also, the barriers include corresponding longitudinal side faces each having a plurality of longitudinally extending zones of different light reflecting properties spaced longitudinally therealong and each of the barriers includes a releasable clamp structure supported therefrom for each zone with the clamp structures being operative to releasably support strip members therefrom in overlying relation relative to the corresponding zone of the barrier side surface.
