Abstract

A drawer lock assembly is provided including a housing having a front face and a rear face; a barrel having a first end extending perpendicularly from the front face of the housing and a second end extending through the rear face of the housing; a locking actuation member disposed through the first end of the barrel; a driver disposed through the second end of the barrel to engage the locking actuation member; a bolt including a first member offset from a second member in a parallel relationship, the first member includes a slot configured to receive a cam of the driver; and an endplate configured to retain the driver and bolt in the housing, the endplate including a channel configured to receive the second member of the bolt, wherein upon actuation of the locking actuation member, the second member extends beyond the housing to engage a recess of a structure.

Claims (26)

1. A drawer lock assembly comprising:

a housing having a front face and a rear face separated by a predetermined width;

a barrel having a first end extending perpendicularly from the front face of the housing and a second end extending to the rear face of the housing;

a locking actuation member disposed through the first end of the barrel;

a driver disposed through the second end of the barrel to engage the locking actuation member;

a bolt including a first member offset from a second member in a parallel relationship, the first member includes a slot configured to receive a cam of the driver; and

an endplate configured to retain the driver and bolt in the housing, the endplate including a channel configured to receive the second member of the bolt,

wherein upon actuation of the locking actuation member by a key, the second member extends beyond the housing to engage a recess of a structure.

2. The drawer lock assembly of claim 1 , wherein the driver includes a first surface and a second surface, the first surface including a slot that is configured to receive a member of locking actuation member, the second surface including cam configured to interact with the bolt to move the bolt into a locked or unlocked position.

3. The drawer lock assembly of claim 2 , wherein the locking actuation member is a key removable core.

4. The drawer lock assembly of claim 1 , wherein the rear surface of the housing includes a recess configured to enable actuation of the first member of the bolt.

6. The drawer lock assembly of claim 5 , wherein the retention plate includes an aperture that receives the cam of the driver and limits the motion of the cam.

7. The drawer lock assembly of claim 1 , wherein the housing includes at least two mounting holes extending from an inner surface of the housing and positioned on opposite sides of the barrel, a leg couples each mounting hole barrel to give structural support to the at least two mounting holes.

8. The drawer lock assembly of claim 7 , wherein at least two mounting holes are recessed from a rear surface of the housing.

9. The drawer lock assembly of claim 1 , wherein the driver includes a circular disc having a first surface and a second surface, the first surface including a first prong and a second prong extending perpendicularly from the first surface and configured to engage the locking actuation member, the second surface including a cam configured to interact with the bolt to move bolt into a locked or unlocked position.

10. The drawer lock assembly of claim 9 , wherein the locking actuation member is a small format interchangeable core, the small format interchangeable core having a first end and a second end, the second end including first and second channels configured to receive the first and second prongs of the driver.

11. The drawer lock assembly of claim 10 , further comprising a retention plate that retains the driver in the recess of the housing, wherein the retention plate includes a semi-circular aperture that receives the cam of the driver and limits the motion of the cam.
