Abstract
An electronic lock device for lockers of similar uses has an input for a user code (keypad or electronic key reader), and a separate input for a manager key. Contacts at the manager key include power jumper contacts, so that when a user is unable to open his assigned locker, whether this is due to a low battery in the lock or failure of the user's key or the user's forgetting a PIN code, the manager key device will open the lock.
Claims15
In combination with a locker for temporary storage of a user's articles, the locker having a door and a movable bolt or latch positioned to secure the door when in extended position and to unlock the door when moved to a retracted position, an electronic lock for controlling the bolt or latch, comprising:
- an inner housing and an outer housing, the inner housing being secured at the inside of the door and the outer housing being secured at a directly opposed position on the outside of the door such that the door is sandwiched between the two housings, with an electrical connection connecting the inner housing to the outer housing, through an opening in the door,
- electronic access means in the outer housing, for receiving a user's access code input by a user,
- an electrically operated drive mechanism connected to the bolt or latch so as to control the position of the bolt or latch,
- microcontroller means connected between the electronic access means and the electrically operated drive mechanism, for changing the position of the bolt or latch when a preselected access code is received by the electronic access means,
- a battery in one of the housings, connected to supply power to the electronic lock, and
- the outer housing further including a terminal with electrical contacts for the combined functions of receiving jump power for a low battery condition and receiving an override access code which will access the lock without the user's access code, whereby a special access device can be engaged with the terminal to provide power and an override access code simultaneously, to open the lock when the lock's battery is low or when the user's access code is lost or forgotten, or both.

A lock unit, comprising:
- a housing,
- a bolt or latch connected to the housing and slidable between extended and retracted positions,
- an electrically operated drive mechanism connected to the bolt or latch in the housing,
- a source of power for the electrically operated drive mechanism,
- control means for connecting power to the electrically operated drive mechanism when the lock unit is properly accessed, to retract the bolt or latch to a retracted bolt position, when the unit is to be in an unlocked mode, and
- a lock accessing device connected to the control means and at a front of the lock unit, including a keypad for input of a user's code to set or to access the lock, and the front of the lock unit further including a terminal with electrical contacts for the combined functions of receiving jump power for a low battery condition and receiving an override access code which will access the lock without the user's access code, whereby a special access device can be engaged with the terminal to provide power and an override access code simultaneously, to open the lock when the lock's battery is low or when the user's access code is forgotten, or both.
