ABSTRACT:
The closure counter-balance is for attachment as a strut between a hingedly mounted movable closure and a support structure. The counter-balance includes a pair of tubular members telescopingly connected together in sliding relationship. A compression coil spring within the members urges the members apart. Means are provided to frictionally lock the tubular members together in any given relative position thereof. Means are also provided to pivotally attach one end of the counter-balance to the support structure, said means including a release mechanism for easy disengagement thereof. The other end of the counter-balance is provided with latch means which cooperate with means on the support structure to lock the counter-balance in the closed position.
