Abstract: The invention concerns a drawer slide assembly, preferably for use in appliances, comprising a catch mechanism for resisting slide extension when the drawer is in a closed position. The catch mechanism is made of a spring arm pivotally mounted to one of the rails and an anchorage point provided in the other rail. When the assembly is moved to the closed position, the anchorage point engages and rotates the spring arm about its axis. Thus, opening the drawer requires a certain force to rotate the spring back. The use of a simple spring arm reduces friction between parts, reduces assembly costs and maintains desired flexibility and tolerance for drawer production and usage.

Abstract: A slide assembly includes a catch assembly secured to a first rail member, and a second rail member in sliding engagement with the first rail member. The second rail member includes a post extending laterally towards the first rail member. The catch assembly includes a catch member pivotable between a post retaining position and a post releasing position. When the catch member is in the post releasing position, movement of the second rail member from an extended position to a retracted position causes the post to engage a bearing surface of the catch member to pivot the catch member from the post releasing position to the post retaining position. The bearing surface of the catch member is contoured to provide substantially continuous and uniform engagement between the bearing surface and the post as the post pivots the catch member from the post releasing position to the post retaining position.

Abstract: A synchronous system for a three-stage ball bearing slide includes a carrier track being inserted into a fixed track to carry a mobile track. Both of the mobile and the carrier tracks engage in reciprocal movement along the same axis direction in relation to the fixed track. A dancer is pivoted to the rear end of the carrier track. The carrier track synchronously slides with the mobile track by a protruding tongue on the mobile track upholding the dancer, and is held in position by having the dancer to uphold a compression bit on the fixed track. A direct push on the extreme where the carrier track is extended releases the dancer from the compression bit to retract once again the carrier track into the fixed track.

Abstract: An improved locking device of sliding drawer comprises a sliding rail and a locking device, when the sliding drawer is pushed back to a cabinet body, the locking device is initiated when a second sliding track moves along the sliding rail towards a direction of the cabinet body.
