Locker lock with outer and inner housings
An electronic locker lock with outer and inner housings similar to that described in U.S. Pat. No. 5,886,644 has a cable connector extending from one housing to the other. When the two housings are installed against outer and inner sides of a locker door, with the door panel sandwiched between housings, the inner housing provides a pocket for storage of the cable after pin connections have been made. In addition, a locking connection is made between the two parts of the pin connector, with a plastic spring lock, preventing disconnection while the lock is in service, and the lock allows for a range of locker door thickness.
1. In combination with a locker for temporary storage of a user's articles, the locker having a door and a movable latch positioned to secure the door when in latched position and to unlock the door when moved to an unlatched position, an electronic lock for controlling the 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 a cable extending from one of the housings and carrying at its end one component of a pin/socket connector, the cable extending through an opening in the door, and the other of the housings having a mating component of the pin/socket connector,
a pocket formed in one of the housings, the pocket being at a side of the one housing adjacent to the door panel, providing an enclosed space for between the one housing and the door panel within which excess length of the cable is fully stowed when the pin/socket connector is assembled together,
electronic access means in the outer housing, for receiving an access code input by a user,
electromagnetic drive means in the inner housing, connected to the latch so as to control the position of the latch,
microcontroller means connected between the electronic access means and the electromagnetic drive means, for causing the drive means to change the position of the latch when a preselected access code is received by the electronic access means, and
a battery in one of the housings, connected to supply power to the electronic lock.
2. The combination defined in claim 1 , wherein the pocket in the one housing comprises a rim extending around a periphery of the one housing so as to be engageable against the door panel, and providing the pocket as a recess formed by the rim and defining said enclosed space.
3. The combination defined in claim 2 , wherein the rim forms a recess of about ¼ inch as said pocket.
4. The combination defined in claim 1 , further including a plastic pin/socket connector lock formed on one of the components of the pin/socket connector to engage with the other component of the pin/socket connector when the connection is made and to retain the pin/socket connector together.
5. The combination defined in claim 4 , wherein the plastic hinge pin/socket connector lock includes a pair of spring arms with a barb at an end of each arm, to engage with the other pin/socket connector component.
6. The combination defined in claim 1 , wherein the one housing having the pocket is the inner housing.
7. The combination defined in claim 1 , wherein the locker door has a standard three-hole locker door prep, the cable of the electronic lock extending through a middle hole of the three-hole door prep and a pair of machine screws extending through the upper and lower holes of the three-hole door prep, the outer housing having internally threaded cylinders extending back on the rear side of the outer housing and through the upper and lower holes of the door prep, and the inner housing having tubular recesses receiving the internally threaded cylinders such that the cylinders can extend to varying distances into the tubular recesses in order to accommodate locker doors of different thicknesses, and the machine screws extending from a back side of the inner housing through the tubular recesses and into the internally threaded cylinders to secure the two housings in place on the locker door.
