  • Patent number: 8608261
    Abstract: A drawer latch assembly. The assembly provides a catch member which is mechanically connected but a separate component from the drawer handle. The drawer handle and catch operate in a concerted pivoting motion and pivot about a common fastener. The drawer handle provides a pair of arms which extend through the front wall of the drawer and have terminal end portions which include the cut out segment which locates and receives a portion of the latch member. In this manner the latch and terminal end portions of the arms are keyed together which alleviates stress on the pivot point and allows for easy repair of the arrangement in the event that either the handle or the catch become damaged.
