Abstract
Abstract A drawer locking lever pivotally mounted between its ends to a drawer mounting strip, with a drawer rail locking element at one end of the lever and an integral deformable spring element at the other end for biasing said locking element toward a drawer rail, there being an actuator element at said other end of the lever for pivoting the lever against the bias of said spring element to release the locking element from the drawer rail.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A one-piece polymeric drawer locking lever comprising: pivotal mount means for pivotally securing said locking lever to an object; a substantially rigid locking arm integral with and extending generally radially from said pivotal mount means and terminating in a locking element; a resiliently deformable spring arm integral with and extending generally radially from said pivotal mount means, said spring arm and said locking arm generally defining an obtuse angle; and a substantially rigid actuator arm integral with and extending generally radially from said pivot mount means, said actuator arm being located outside of said obtuse angle, whereby said actuator arm can be shifted to pivot said lever about said pivot mount means deforming said spring arm and shifting said locking arm.
Claim 2
Dependent Claim
121 words
A one-piece polymeric drawer locking lever comprising: pivotal mount means for pivotally securing said locking lever to an object; a substantially rigid locking arm integral with and extending generally radially from said pivotal mount means and terminating in a locking element; a resiliently deformable spring arm integral with and extending generally radially from said pivotal mount means, said spring arm and said locking arm generally defining an obtuse angle; and a substantially rigid actuator arm integral with and extending generally radially from said pivot mount means, said actuator arm being located outside of said obtuse angle, whereby said actuator arm can be shifted to pivot said lever about said pivot mount means deforming said spring arm and shifting said locking arm.
Claim 3
Dependent Claim
26 words
The drawer locking lever in claim 1 wherein said actuator element comprises a depressor surface and an opposite overspring stop to limit pivoting of said lever.
Claim 4
Dependent Claim
31 words
The drawer locking lever in claim 1 further comprising stop means integral with said locking arm for limiting the shifting of said locking arm under the bias of said spring arm.
Claim 5
Dependent Claim
15 words
The drawer locking lever in claim 3 wherein said stop means comprises a projecting tab.
Claim 6
Dependent Claim
142 words
A drawer mounting strip and locking lever combination comprising: an elongated drawer mounting strip having a vertical element for attachment to a drawer, and a lateral element; a one-piece locking lever having a pair of generally opposite ends and pivotal mount means between said ends for pivotally mounting said lever to said vertical element; an integral locking element at one of said ends releasably engaging said lateral element upon pivotal movement of said lever; an integral deformable spring at the other of said ends in resilient engagement with said lateral element and having an inherent bias to serve as a spring for shifting said locking element toward engagement with said lateral element; and an integral actuator portion at said other end to allow manual pivoting of said lever for deformation of said spring against its inherent bias to release said locking element.
Claim 7
Dependent Claim
142 words
A drawer mounting strip and locking lever combination comprising: an elongated drawer mounting strip having a vertical element for attachment to a drawer, and a lateral element; a one-piece locking lever having a pair of generally opposite ends and pivotal mount means between said ends for pivotally mounting said lever to said vertical element; an integral locking element at one of said ends releasably engaging said lateral element upon pivotal movement of said lever; an integral deformable spring at the other of said ends in resilient engagement with said lateral element and having an inherent bias to serve as a spring for shifting said locking element toward engagement with said lateral element; and an integral actuator portion at said other end to allow manual pivoting of said lever for deformation of said spring against its inherent bias to release said locking element.
Claim 8
Dependent Claim
25 words
The drawer mounting strip and locking lever combination in claim 5 wherein said lever, locking element, spring, and actuator portion comprise a unitary, polymeric element.
Claim 9
Dependent Claim
33 words
The drawer mounting strip and locking lever combination in claim 5 wherein said actuator portion includes an overspring stop to limit pivoting of said lever and thereby prevent excessive deformation of said spring.
Claim 10
Dependent Claim
33 words
The drawer mounting strip and locking lever combination in claim 5 including a stop surface on said locking element to limit the shifting of said locking element under the bias of said spring.
