Abstract: A lock assembly includes a lock body with a shackle. The shackle has a leg. A locking element is disposed in the lock body and is selectively engageable to the shackle. A cam is disposed in the lock body and includes a locked position, an unlocked position and a shackle removal position. The leg includes a shackle removal recess that only partially extends circumferentially about an outer peripheral surface disposed about a longitudinal axis of the leg and is sized to receive the first locking element sufficiently to permit movement of the cam to the shackle removal position. The shackle is rotatable in the unlocked position to expose the shackle removal recess to the locking element.

A cam is disposed in the lock body. The cam has a lock position for moving the locking element to engage the shackle. There is also an unlocked position for moving the locking element to disengage the shackle. The cam has a shackle removal position for removing the shackle from the lock body. The leg has a shackle removal recess sized to receive the locking element sufficiently so as to permit movement of the cam to the shackle removal position. The cam is configured to displace the locking element into the shackle removal recess.

Abstract: A curved shackle gunlock for rendering a gun inoperative from accidental or unauthorized use and for deterring theft. The unique shape of the shackle is critical and will fit most firearms, specifically an automatic rifle. The thickness of the shackle provides maximum protection against destruction and violation. The gunlock can be inserted in the opening of a handgun through the breach and magazine well, through the revolver frame, through the loading port of a shotgun, or through the magazine well of a specialty gun.

Abstract: A combination lock having a housing, a shackle, a dial, a pushbutton, and a lock assembly. The lock assembly is made of a group of rotating disks having windows that can be aligned to open the lock. When the dial is turned according to the combination of the lock, the windows become aligned so that the user can depress the pushbutton to release the shackle. The pushbutton travels in a direction that is perpendicular to the axis of rotation of the dial. When the shackle is locked again, the pushbutton returns to its original position. As the pushbutton travels back to its original position, portions of the lock assembly are turned so that the combination must be reentered in order to reopen the lock.

Abstract: A turnable lock operable with driver and tumbler pins when positioned by a key at a shear line in which shearable assembly pins are assembled in the lock and thereafter sheared to form such driver and tumbler pins for operation thereon. Each assembly pin is selectively weakened at a plurality of locations which correspond with notched depth heights of the family of keys capable of insertion in the keyhole. Such weakening is controlled so that pin shearing can be accomplished by application of rotational or linear forces applied to any part of the lock except the key. When linear forces are used the tumbler or plug may be indexed to employ a driver pin as a plug lock.
