Drawer slide and locking mechanism
First Claim
Patent Images
1. A lock mechanism comprising:
- a latch receiver rotatably mounted to a base;
a lever arm rotatably mounted to the base, the lever arm rotatable to a ready position in which a first end of the lever arm blocks rotation of the latch receiver in a first direction when the latch receiver is in a locked position; and
a motor rotationally coupled to a cam such that rotation of the motor causes the cam to rotate the lever arm in at least one direction to decouple the lever atm from the latch receiver, so that the latch receiver is rotatable from the locked position to an unlocked position, the motor drivably coupled to the lever arm about a second end of the lever arm, the second end opposing the first end, the lever arm having a length defined by and bounded by the first end and the second end, with the lever arm rotatably mounted to the base along the length and between the two ends;
the lever arm rotatable to the ready position when the latch receiver is in the unlocked position.

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.

13. A lock mechanism comprising:
-
a latch receiver rotatably mounted to a base; a lever arm rotatably mounted to the base at a position along a length of the lever arm, the lever arm rotatable to a ready position in which a first portion of the lever arm on a first side of the rotatable mounting position blocks rotation of the latch receiver in a first direction; and a motor drivably coupled to the lever arm by a cam, the cam configured to contact a second portion of the lever arm on a second side of the rotatable mounting position, to rotate the lever arm out of the ready position, decoupling the lever arm from the latch receiver, and wherein the lever arm is rotatable to the ready position with the latch receiver rotated away from the lever arm; wherein the second side and the first side have the rotatable mounting position therebetween; wherein the cam includes at least one cam stop to prevent over rotation of the cam. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A lock mechanism, adaptable for use with a drawer slide, the lock mechanism comprising:
-
a latch receiver rotatably mounted to a base; a lever arm rotatably mounted to the base, the lever arm rotatable to a ready position in which the lever arm blocks rotation of the latch receiver in one direction; a motor rotationally coupled to a cam, the cam coupled to the lever arm to rotate the lever arm in at least a first direction to decouple the lever arm from the latch receiver; a lip extending parallel to the base for coupling to a slide member of the drawer slide; and a housing enclosing the latch receiver, lever arm and the motor. - View Dependent Claims (28, 29, 30, 31, 32, 33)
