Abstract
Abstract A drawer assembly which prevents a drawer from "jamming up" in a locked position when the drawer is slammed shut while a locking arm associated with a key lock on the drawer is in a locking position. A projection on a retainer clip located on the inside of the front panel of the drawer keeps the locking arm from being bent, and also keeps the drawer from moving to the closed position from which a latching mechanism asociated with the drawer would be placed in a locked position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
274 words
A drawer assembly comprising: a frame; a drawer having a front panel; mounting means for mounting said drawer for movement between open and closed positions relative to said frame; a key lock mounted in said drawer, with said key lock having a locking arm moveable between locking and unlocking positions by a key associated with said key lock; said frame having an abutment member with said abutment member having a locking side and a non-locking side, said abutment member cooperating with said locking arm to lock said drawer in said closed position when said locking arm is moved to said locking position by said key to engage said locking side of said abutment member after said drawer is moved to said closed position; a latching mechanism coupled between said drawer and said frame for latching said drawer in said closed position when said drawer is moved to said closed position and for unlatching said drawer permitting it to move towards said open position upon at least one predetermined event, with one said predetermined event being the movement of said locking arm from said locking position to said unlocking position; and support means positioned between said front panel and said locking arm to provide support for said locking arm when said locking arm is inadvertently placed in said locking position prior to said drawer being moved to said closed position to thereby prevent bending of said locking arm when contacting said non-locking side of said abutment member and also to prevent said drawer from being moved close enough to said closed position which would cause said latching mechanism to latch said drawer to said frame.
Claim 2
Dependent Claim
274 words
A drawer assembly comprising: a frame; a drawer having a front panel; mounting means for mounting said drawer for movement between open and closed positions relative to said frame; a key lock mounted in said drawer, with said key lock having a locking arm moveable between locking and unlocking positions by a key associated with said key lock; said frame having an abutment member with said abutment member having a locking side and a non-locking side, said abutment member cooperating with said locking arm to lock said drawer in said closed position when said locking arm is moved to said locking position by said key to engage said locking side of said abutment member after said drawer is moved to said closed position; a latching mechanism coupled between said drawer and said frame for latching said drawer in said closed position when said drawer is moved to said closed position and for unlatching said drawer permitting it to move towards said open position upon at least one predetermined event, with one said predetermined event being the movement of said locking arm from said locking position to said unlocking position; and support means positioned between said front panel and said locking arm to provide support for said locking arm when said locking arm is inadvertently placed in said locking position prior to said drawer being moved to said closed position to thereby prevent bending of said locking arm when contacting said non-locking side of said abutment member and also to prevent said drawer from being moved close enough to said closed position which would cause said latching mechanism to latch said drawer to said frame.
Claim 3
Dependent Claim
36 words
The drawer assembly as claimed in claim 1 in which said support means includes a projection which extends from said front panel towards said locking arm when said locking arm is moved to said locking position.
