Abstract:
A combination operated lock for use with a security container that has a zippered closure operated by a pull tab movable between open and closed positions, with the lock being operable, when locked, to retain the pull tab in closed position until the lock is unlocked by setting a combination. The lock preferably has a housing connected to a flexible fabric wall of the security container, and dials that are turned to set a combination for unlocking the lock. In some embodiments, the lock cannot be unlocked unless and until a one-use seal is broken and removed from the housing to which the seal was attachable only after the lock was locked.
Abstract:
A combination operated padlock has indicia carrying dials that are turned to set a combination for unlocking a shackle of the padlock. Operating components of the padlock are carried by or within a housing-enclosed frame of the padlock. A strong, corrosion resistant insert, preferably formed from brass of uniform thickness, is configured to fit cleverly around and among the movable operating components to strengthen the padlock and to prevent operating component manipulation if an unauthorized unlocking of the padlock is attempted. In a preferred embodiment, the insert has two substantially identical question-mark-shaped tines configured to extend toward and between different adjacent pairs of the dials that are turned to set a combination.
Abstract:
Locks for luggage, travelcases, briefcases and the like that can be operated by setting a combination or by using a key include an indicator to provide a signal in response to use of the key. The locks retain relatively movable components in latched engagement when locked, and permit relative movement of the components when unlocked. In some embodiments, the indicator provides a visual signal if an associated travelcase has been opened for inspection by unlocking the associated lock using a key; and, in some embodiments, the indicator can be reset upon entry of a proper combination.
Abstract:
A tubular lock and its operating key have safety features that render the lock and key well suited for use with food freezer appliances and the like where the keyway of the lock extends horizontally. The tubular portion of the operating key, and the keyway of the tubular lock are cooperatively configured so a key inserted into the keyway of the lock fits quite loosely and is minimally supported even when fully inserted. The graspable bow of the operating key is made unusually long causing the center of gravity of an inserted operating key to be spaced far from the front face of the lock—so the weight of the loosely fitting and minimally supported operating key levers the graspable bow downwardly, causing the key to drop from the keyway unless being held in the keyway. Gravity is optimally used to effect key ejection.
