Abstract
The invention is a tool having contoured opposing jaws for fully engaging hexagonally shaped fasteners on at least four sides for any fastener within the operating range of the tool. The jaws include a two-surfaced jaw and an opposingly disposed three-surfaced jaw. The jaw surfaces are configured and positioned relative to one another in such a way as to maintain a shape which conforms to that of the fastener's hexagonal shape during adjustment.
Claims7
A tool having at least one handle and positionable jaws for engaging various sized hexagonally shaped objects within the operating range of said tool, comprising:
- a first primary jaw integral with said handle and opposingly disposed second primary and auxiliary jaws, which are movably positionable on said handle whereby said second primary and auxiliary jaws move on a linear axis in relationship to one another;
- said first primary jaw having an angularly disposed base and extended jaw surfaces;
- said second primary jaw having a guide and angularly disposed base, intermediate and extended jaw surfaces;
- said auxiliary jaw having a projection which is slidingly received by said guide and which terminates in jaw surface;
- and
- said second primary and auxiliary jaws being movable relative to one another and each being movable relative to said first primary jaw, whereby movement of said second primary and said auxiliary jaws is effected by rotation of a common shaft having respective worm gear surfaces corresponding to each of said second primary and auxiliary jaws such that said first primary, second primary and auxiliary jaws may be adjusted to simultaneously engage five sides of various sized hexagonally shaped objects.
