Abstract:
A collapsible tool includes at least one handle having first and second handle portions and hinge that allows the tool to benefit from the leverage and mechanical advantage of a full-size tool, yet is easily and quickly collapsible and extendable. In one embodiment, the first handle portion includes one or more spring-biased detents that contact engagement portions (preferably semi-circular surfaces) disposed on the second handle portion and secure the handle in the extended position. A pivot is disposed through the handle portions in the direction of the force moment produced during use. Alternatively, the first handle portion includes a base having three supports, a cavity, and a biased tab disposed within the cavity. The second end includes a bevel region and a notch region. In the extended position, the biased tab engages the notch region and secures the second handle portion between the biased tab and the supports.
