Abstract

1,221,457. Counterbalancing. NISSEN CORP. 4 Sept., 1968 [15 Sept., 1967], No. 42124/68. Heading B8B. [Also in Divisions A6 and F2] A counterbalance for gymnastic apparatus consists of a spring unit, Fig. 2, insertable in a telescopic support leg 10, Fig. 1, of the apparatus. The unit includes at least one constantforce spring 40 of the kind comprising a rolledup resilient strip 46. When the unit is installed in the leg 10, the load-bearing element 12 of the leg rests by its inner surface 48 on the spring 46 and causes the latter to unroll as the element 12 descends. The leg shown is attached to one of a pair of parallel bars 22, the pair of bars being supported by a total of four such legs whose constant-force springs together exert a force equal to the weight of the bars. In use, each leg is locked at a required extension by a clamp 24. The purpose of the counterbalances is (a) to make readjustment of the height of the bars easy when the clamps are released and (b) to ensure that if a clamp 24 disengages accidentally the leg will not suddenly collapse. Fig. 4 (not shown) depicts a counterbalance unit having two rolled-up springs each of which consists of two layers of resilient strip rolled up together. This unit is for insertion in one of the two legs 10<SP>1</SP>, Fig. 3 (not shown), supporting a balance beam (60). Counterbalanced support legs for gymnastic horses and backs are also mentioned in the Specification.
