Abstract
By providing an automatically displayed, easily seen, positive visual indicator on a combination lock each time the combination lock is placed in its combination set or re-set position, a unique, easily used, enhanced combination lock is realized. Preferably, the visual indicator is automatically displayed upon entry of the lock into its combination setting or resetting position, thereby providing the user with a positive, readily seen, visual display clearly informing the user that the combination sequence may be altered. Furthermore, the lock construction of the present invention is constructed with the interior chambers thereof virtually sealed from ambient surroundings, thereby preventing unwanted contamination from entering the interior of the lock and the rotating components thereof. In this way, degradation by contamination is virtually eliminated. Finally, the present invention preferably employs a minimum number of components in combination with a housing and a movable shackle in order to provide the desired, unique combination lock construction of this invention. As a result, a cost effective, high quality combination lock is attained.
