Abstract

The key pad assembly includes a housing that attaches to a secure container. The housing has a front wall, and a key pad attaches to the front face of the front wall. A cylindrical side wall extends back from the front wall. The side wall is truncated at an angle to angle the front face to the door. Where the side wall is widest, which should be at the bottom of the housing, the side wall has a removable section through which a battery can be inserted. A cable extends through an opening in the front face from the key pad to a circuit board that mounts the combination sensing circuit. The cable is flat with multiple electric conductors and a slot. When the key pad and circuit board are properly assembled, the cable slot fits over a fixed pin in the housing. The pin secures the cable so that it is not pulled from its connection with the key pad or the circuit board. Other pins within the housing mount the circuit board. Parallel walls from the rear of the front face create a cavity for the battery. The side walls that create a battery chamber each has a shaft with an opening that extends through the front wall. The shafts supply support for bolts attaching the housing to the secure container. When the key pad is attached to the housing, the pad covers the openings.

Dependent claims

A key paid assembly comprising:

a housing attachable to a secure container, the housing having a front wall with a front facing outside of the housing and a rear face facing inside the housing, a side wall extending away from the front wall, the housing further having an inside behind the front wall;
a key pad attachable to the front face of the front wall of the housing, the key pad having a plurality of keys, each key sending a signal to a sensing circuit when the key is pressed;
a cable containing a plurality of conductors, the cable extending from the key pad and being attachable to the sensing circuit;
the sensing circuit being mounted on a circuit board inside the housing;
a cable opening through the front face from the outside to the inside, the cable passing through the cable opening into the housing;
a slot through the cable on a portion of the cable spaced from the key pad and from the sensing circuit;
and
a pin on the inside of the housing positioned to engage the slot of the cable to limit movement of the cable and
at least two openings through the front face and a shaft extending around the openings through the front face and a shaft extending around the openings, a battery container within the housing for receiving a battery the battery container comprising a pair of battery walls extending from the front wall of and spaced to receive a battery and a battery opening in the side wall adjacent to the battery container of sufficient size to allow insertion and removal of the battery through the battery opening, each shaft being attached to one of the side walls of the battery container.
