  • Patent number: 6170927
    Abstract: A drawer interlinking system for a storage cabinet is disclosed herein. The cabinet includes a frame, a first sliding assembly, and a second sliding assembly. Each sliding assembly is movable between an extended position and a retracted position relative to the frame. The frame includes a flexible member coupled at a first end to the first sliding assembly. The line is directed by a first guide coupled to the frame in association with the first sliding assembly, a guide assembly coupled to the frame and spaced apart from the first guide, a glide assembly coupled to the frame by a tension member, and a second guide coupled to the frame in association with the second sliding assembly and spaced apart from the guide assembly. The flexible member is coupled at a second end to the second sliding assembly, so that when one sliding assembly is extended from the frame the other sliding assembly is retracted into the frame. The guide assembly can comprise a left pulley connected to a right pulley.
