Abstract

Abstract A non-exposed drawer lock for locking a drawer to its surrounding case. The drawer front is flush with the edge of the work surface with the lock completely hidden from view. A spring urged slidable locking bar is mounted to the drawer case which permits the drawer to be opened slightly while still in a locked configuration thus exposing the lock to thereby permit the drawer to be unlocked and opened completely.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 99 words
In combination, a drawer case, a drawer including a front panel, slidable in said drawer case and locking means for locking said drawer to said drawer case; said locking means including a locking bar and a lock, said locking bar being mounted on said drawer case for limited reciprocal motion with respect to said drawer case, said lock being mounted in the front panel of said drawer and adapted to interconnect with said locking bar; said locking means permitting limited relative slidable movement between said drawer and said drawer case while said locking bar and said lock are interconnected.
Claim 2
Dependent Claim 99 words
In combination, a drawer case, a drawer including a front panel, slidable in said drawer case and locking means for locking said drawer to said drawer case; said locking means including a locking bar and a lock, said locking bar being mounted on said drawer case for limited reciprocal motion with respect to said drawer case, said lock being mounted in the front panel of said drawer and adapted to interconnect with said locking bar; said locking means permitting limited relative slidable movement between said drawer and said drawer case while said locking bar and said lock are interconnected.
Claim 3
Dependent Claim 34 words
The combination according to claim 1 wherein said reciprocal motion is limited by a pair of spaced stops projecting from said locking bar and adapted to coact with a portion of said drawer case.
Claim 4
Dependent Claim 67 words
The combination according to claim 2 wherein spring means is connected between said locking bar and said drawer case urging said locking bar toward a closed position against a first of said spaced stops, said combinaton permitting said drawer when in a locked condition to be opened a limited distance against the action of said spring, said distance being limited by the other of said spaced stops.
Claim 5
Dependent Claim 51 words
The combination according to claim 3 wherein top means overlies said lock in the front panel of said drawer when said drawer is in said closed position, said lock being uncovered when said drawer is in said limited open position thereby rendering said lock accessible for purposes of unlocking said drawer.
Claim 6
Dependent Claim 156 words
In combination, a drawer, a drawer case and locking means for locking said drawer in said drawer case, said drawer case adapted for mounting to the underside of a work surface, said drawer including a front panel and a body portion, said body portion constructed and arranged to be slidably received in said drawer case and said drawer front panel adapted to underlie said work surface when said drawer is in a fully closed position, said locking means including a locking bar mounted to said drawer case for limited reciprocal movement therewith and a lock in the inner surface of said drawer front panel, whereby when said locking bar and said lock are engaged and said drawer is in its fully closed position said lock underlies said work surface, said drawer being movable to a lock exposed position while said locking bar and said lock remain engaged through the limited reciprocal movement of said locking bar.
Claim 7
Dependent Claim 156 words
In combination, a drawer, a drawer case and locking means for locking said drawer in said drawer case, said drawer case adapted for mounting to the underside of a work surface, said drawer including a front panel and a body portion, said body portion constructed and arranged to be slidably received in said drawer case and said drawer front panel adapted to underlie said work surface when said drawer is in a fully closed position, said locking means including a locking bar mounted to said drawer case for limited reciprocal movement therewith and a lock in the inner surface of said drawer front panel, whereby when said locking bar and said lock are engaged and said drawer is in its fully closed position said lock underlies said work surface, said drawer being movable to a lock exposed position while said locking bar and said lock remain engaged through the limited reciprocal movement of said locking bar.
Claim 8
Dependent Claim 29 words
The combination according to claim 5 wherein spring means interconnects said locking bar and said case, said spring means urging said locking bar inwardly with respect to said case.
Claim 9
Dependent Claim 47 words
The combination according to claim 5 wherein said locking bar includes a pair of spaced stop members thereon, said pair of spaced stop members coacting with a portion of said case to limit the extent of reciprocal movement of said locking bar with respect to said case.
Claim 10
Dependent Claim 204 words
In combination, a drawer case and drawer adapted for mounting to the underside of a work surface, said drawer case comprising; at least a pair of spaced side walls having guide rails on the inner surface thereof, and a locking mechanism support bar interconnecting said side walls adjacent the front ends thereof; said drawer comprising; a drawer front panel and a drawer body having external side rails constructed and arranged to ride on the guide rails on said side walls and lock means mounted on the inner side of said drawer front panel adjacent the top edge thereof; and a lock bar guide mounted to the underside of said locking mechanism support bar, a traveling lock bar mounted in said lock bar guide for reciprocating movement therein, said traveling lock bar including a front stop and a back stop and a pair of lock engaging projections on the forward end thereof; and spring means connected to said traveling lock bar and urging said front stop against said lock bar guide whereby said drawer, when said lock engaging projections are locked into said lock means of said drawer front panel, can be moved from a closed position to a slightly open position while remaining locked.
Claim 11
Dependent Claim 204 words
In combination, a drawer case and drawer adapted for mounting to the underside of a work surface, said drawer case comprising; at least a pair of spaced side walls having guide rails on the inner surface thereof, and a locking mechanism support bar interconnecting said side walls adjacent the front ends thereof; said drawer comprising; a drawer front panel and a drawer body having external side rails constructed and arranged to ride on the guide rails on said side walls and lock means mounted on the inner side of said drawer front panel adjacent the top edge thereof; and a lock bar guide mounted to the underside of said locking mechanism support bar, a traveling lock bar mounted in said lock bar guide for reciprocating movement therein, said traveling lock bar including a front stop and a back stop and a pair of lock engaging projections on the forward end thereof; and spring means connected to said traveling lock bar and urging said front stop against said lock bar guide whereby said drawer, when said lock engaging projections are locked into said lock means of said drawer front panel, can be moved from a closed position to a slightly open position while remaining locked.
