Drawer slide and locking mechanism
First Claim
Patent Images
1. A drawer slide with lock mechanism, comprising:
- an outer slide member with an elongate web bounded by raceways;
an inner slide member nested within the raceways and having a latch arm, the inner slide member extendible with respect to the outer slide member, the inner slide member substantially within a volume defined by the outer slide member when the inner slide member is in a non-extended position with respect to the outer slide member, the inner slide member and the outer slide member configured to extensibly couple a drawer to a cabinet;
a latch receiver rotatably mounted with respect to the outer slide member in a travel path of the latch arm;
a lever arm rotatably mounted with respect to the outer slide member, the lever arm rotatable to a position to block rotation of the latch receiver in at least a first direction; and
a motor drivably coupled to the lever arm to rotate the lever arm in at least one direction;
wherein the latch receiver includes a basin configured to receive the latch arm.

Abstract
A drawer slide with lock mechanism has an elongated outer slide member extendably coupled to an inner slide member. A latch arm or pin is fixed to the inner slide member for latching by a lock mechanism fixed to the outer slide member. The lock mechanism uses a latch receiver that rotates with respect to the lock mechanism and is in a travel path of the latch arm. A lever arm rotates with respect to the lock mechanism and is positionable to block rotation of the latch receiver in a locked position to retain the latch arm. A motor drives a cam to position the lever arm to free the latch receiver from the locked position.

12. A locking drawer slide, comprising:
-
a first slide member; an intermediate slide member extendably coupled to the first slide member along a first axis, the intermediate slide member nested within the first slide member; a second slide member extendably coupled to the intermediate slide member along the first axis, the second slide member nested within the intermediate slide member; a pin extending from the second slide member substantially perpendicular to the first axis; a latch receiver pivotably fixed with respect to the first slide member, the latch receiver positionable in an open position for receiving the pin and positionable in a closed position for retaining the pin; a lever arm pivotably fixed with respect to the first slide member, the lever arm positionable in a release position for allowing pivoting of the latch receiver and positionable in a locking position for holding the latch receiver in the closed position by blocking rotation of the latch receiver toward the open position; a cam arranged to pivot the lever arm by pushing a cam follower portion of the lever arm; and a motor rotationally coupled to the cam; wherein the latch receiver comprises; a u-shaped portion formed of a first leg and a second leg substantially parallel to the first leg; and a third leg extending outward from the pivot axis of the latch receiver and substantially perpendicular to the first leg and the second leg. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A locking drawer slide, comprising:
-
a first slide member; an intermediate slide member extendably coupled to the first slide member along a first axis, the intermediate slide member nested within the first slide member; a second slide member extendably coupled to the intermediate slide member along the first axis, the second slide member nested within the intermediate slide member; a pin extending from the second slide member substantially perpendicular to the first axis; a latch receiver pivotably fixed with respect to the first slide member, the latch receiver positionable in an open position for receiving the pin and positionable in a closed position for retaining the pin; a lever arm pivotably fixed with respect to the first slide member, the lever arm positionable in a release position for allowing pivoting of the latch receiver and positionable in a locking position for holding the latch receiver in the closed position by blocking rotation of the latch receiver toward the open position; a cam arranged to pivot the lever arm by pushing a cam follower portion of the lever arm; and a motor rotationally coupled to the cam; wherein the pin is attached to the second slide member by a tab extending along the first axis and beyond an end of the second slide member.
