ABSTRACT:
A key-operated keeper lock for a slide fastener includes an outer tubular barrel, an anvil projecting radially from the barrel and adapted for supporting a fastener lacing element thereon, a tubular handle rotatable in the barrel, means securing the handle against substantial axial movement relative to the barrel, a keeper arm fixed to and projecting radially from the handle for rotation therewith and adapted to overlie the anvil and a fastener lacing element thereon for retaining the lacing element between the keeper arm and the anvil to prevent operation of the fastener, a lock cylinder rotatable in the handle, tumbler means movable between the lock cylinder and the handle for alternately preventing and enabling rotation of the lock cylinder relative to the handle, a lock bolt mounted in the handle and movable when the keeper arm overlies the anvil between a position locking the handle to the barrel and an unlocking position freeing the barrel for rotation, and means coupling the lock cylinder and the lock bolt for moving the bolt between its said positions in response to rotation of the lock cylinder, said handle and said keeper arm being adapted upon movement of the lock bolt to its unlocking position to rotate between the position of the keeper arm overlying the anvil and an out-of-the-way position wherein the lacing element is accessible for manipulation, while each remains substantially in a constant axial disposition relative to the barrel.
