ABSTRACT:
A spring support device has a housing; a coil spring having one end supported in the housing and another end carrying a spring disc; at least two bell crank levers arranged on the spring disc symmetrically to the coil spring; and a fulcrum slidably and pivotally supporting each bell crank lever on the spring disc. Each bell crank lever has a first arm extending from the fulcrum generally parallel to a radial plane of the coil spring and each bell crank lever has a second arm extending from the fulcrum at an angle to the first arm. The first and second arms have an end remote from the fulcrum. A pull rod has one end adapted to carry a load and another end at least indirectly articulated to the end of each first arm. The spring support device further comprises a mechanism for guiding the end of each second arm in a stationary, arcuate path oriented generally parallel to an axial plane of the coil spring.
