Patent ID: 8511531

Claim:
A fastening device comprising: a housing, a manually operable handle, a plunger for ejecting fasteners from the fastening device, a spring adapted to control movement of the plunger wherein the spring is operable between a decompressed state and a compressed state upon depression of the handle, a manually operable latch protruding from the housing and operably mounted on said housing apart from the handle, wherein said manually operable latch is configured for retaining the plunger when the spring is in the compressed state thereby storing energy generated from compression of the spring and for releasing the plunger upon direct actuation of the manually operable latch by a user to cause a fastener to be ejected from the fastening device, and a safety lever operatively connected to the fastening device wherein the safety lever prevents the manually operable latch from actuating when the manually operable handle is in a released position and wherein the safety lever allows the manually operable latch to actuate when the manually operable handle is in a depressed position.
