A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

A sliding device is provided for a drawer which may provide a detent function by an elastic displacement to a rail member enabling a storage body to be moved from a main body in a sliding manner, thereby implementing a fixed maintenance force having a more robust state at a drawn-into location of the storage body to the main body. The sliding device includes: a first rail member which has a locking projection, an intermediate rail member coupled to be movable with respect to the first rail member, a second rail member coupled to be movable with respect to the intermediate rail member at a location opposite to the first rail member, and a detent member which is provided on the second rail member, and has an opening which accommodates the locking projection and a constraining protrusion which suppresses the locking projection from being separated from the opening.

The invention relates to a child safety latch for limiting movement of moveable elements, comprising a prong assembly secured to one element, and an anchor assembly secured to the other element for capturing the terminal end of said prong, said anchor assembly including a receiver to receive and capture said terminal end to stop movement relative movement of the elements by automatic engagement of the receiver of the anchor assembly with the terminal end, the prong assembly being movable by a user between a first position in which the terminal end is captured by the receiver preventing movement of one element with respect to the other element and a second position in which the terminal end is released from the receiver permitting relative movement of the respective elements. The prong is resilient and returns to the first position after release by the user such that when one element is moved back towards the other element, the latch is automatically reactivated such that subsequent movement of one element away from the other element by the specified distance will result in re-engagement of the terminal end and the receiver. The prong assembly preferably includes a strip of resilient metal, and the terminal end of the prong assembly includes an oval shaped opening which corresponds with the receiver which is in the form of a ramp shaped catch on the anchor assembly.

A slide rail locking device includes an upper locking plate coupling a supporting bar mounted on an inside wall of a main body and a slide rail fixed to a side or bottom surface of a drawer, located above the supporting bar, and locked into the slide rail, a lower locking plate located below the supporting bar, a connection plate connecting the upper locking plate and the lower locking plate, and an extended plate formed by being bulged down from the lower locking plate to face the upper locking plate. A gap is formed between the slide rail locking device and a vertical supporting bar, whereby undesired movement of the slide rail locking device generated by a drawing motion of the drawer being drawn out of and retracted into the main body may be offset.

A slide rail assembly includes a first rail, a second rail, a first locking mechanism, and a second locking mechanism. The second rail can be displaced with respect to the first rail. The first locking mechanism and the second locking mechanism are disposed at two different portions of the second rail respectively and can be locked to the first rail separately in order to keep the second rail at either of two predetermined extended positions. The first locking mechanism and the second locking mechanism can then be operated and thereby unlocked from the first rail so that the second rail can be retracted with respect to the first rail.
