ABSTRACT:
A mechanism for use in controlling vertical movement of a surface, such as a table top, supported for movement between upper and lower vertical positions, including a counterbalance mechanism for counterbalancing at least part of the weight of the surface and/or a weight placed thereon, and a brake mechanism for releasably retaining the surface in a selected vertical position. The counterbalance mechanism includes a member having a first end supported for pivotal movement about a first axis and a spring tending to opposed pivotal movement of the member in a direction corresponding to lowering movement of the surface; and the brake mechanism includes a brake rod having one end supported for pivotal movement about a second axis disposed parallel to the first axis and a brake rod clamping mechanism supported by the member for pivotal movement about a third axis disposed parallel to the first axis and supported by the brake rod for movement lengthwise thereof with the clamping mechanism normally clamping against the brake rod to prevent pivot movement of the member in the direction corresponding to lowering movement of the surface, and an operator for manually releasing the clamping mechanism from clamping engagement with the brake rod.
