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.
Claims17
A drawer slide with lock mechanism, comprising:
- a first slide member with an elongate web bounded by raceways and a second slide member with an elongate web bounded by bearing raceways, with the first and second slide members extendably coupled by way of bearings in the raceways and with one of the first and second slide members configured for mounting to a drawer;
- a latch arm positioned on the first slide member, the latch arm extending from the first slide member towards the elongate web of the second slide member:
- a latch receiver rotatably mounted with respect to the second slide member, the latch receiver defining a basin in a travel path of the latch arm, the latch receiver being rotatable from an open position to receive the latch arm and a closed position for retaining the latch arm;
- an elongate lever arm with a length bounded between a top end and an opposite end, the lever arm rotatably mounted along its length between the top end and the opposite end with respect to the second slide member, the lever arm rotatable from an unlocking position in which the lever arm is spaced away from the latch receiver to a locking position in which the top end of the lever arm blocks rotation of the latch receiver in at least a first direction in the closed position;
- and a motor drivably coupled to the lever arm to rotate the lever arm from the locking position to the unlocking position in a second direction out of a travel path of the latch receiver.
2-26. (canceled)
An assembly including a lock mechanism, comprising:
- a housing for mounting within a cabinet, the housing having an open slot providing access to an interior of the housing;
- a latch receiver rotatably mounted at least partially within the housing, the latch receiver rotatable between a locked position and an unlocked position, with a basin of the latch receiver facing the open slot with the latch receiver in the unlocked position;
- a lever arm of elongate form rotatably mounted at least partially within the housing, a pivoting point of the lever arm located between a first portion of the lever arm and a second portion of the lever arm, the lever arm rotatable between a locking position, in which the first portion of the lever arm blocks rotation of the latch receiver in a first direction with the latch receiver in the locked position, and an unlocking position in which the lever arm does not block rotation of the latch receiver in the first direction, the lever arm not in contact with the latch receiver with the latch receiver in the unlocked position;
- an electrically actuated actuator mounted at least partially within the housing;
- and
- a cam, the cam drivably coupling the electrically actuated actuator to the lever arm, to rotate the lever arm in at least one direction from the locking position to the unlocking position.
