Safety for knife-blade lock

摘要

A knife (10) has a folding blade (12), a blade lock (28) in the form of a leaf spring (24a), and a safety (30) for preventing unlocking of the lock (28). One form of safety (30) has a carrier in the form of an elongate arm (34) mounted on the knife handle (18). A stud (32) is positioned on an inside surface of one end of the arm (34). A contact surface (34b) is formed on an outside surface of the arm (34) opposite from the stud (32). The other end of the arm (34) is pivotably attached to the handle (18) of the knife (10). The arm (34) may be swung from a release position, unobstructive of the lock (28), to a safety position in which the presence of the stud (32) prevents unlocking the lock (28). The carrier (54) may be spring (56) biased toward the release position, and may have limited travel away from the handle (18) to the release position. The carrier may also be a slide (64) or a rotating disk (74). <IMAGE>
