ABSTRACT:
A motion transmitting remote control assembly (10) includes a length adjustment device on its core element (14) which is composed of a slider (20) and a housing (24). A push button lock (34) joins the slider (20) and housing (24) in a length adjusted position. A ball socket receptacle (28) attaches the housing (24) to a control member (30). The slider (20) is biased into the housing (24) by a compression spring (40). A backstop (42) extends rearwardly from the housing (24) to provide a bearing surface for the spring (40). The backstop (42) is slidably connected to the housing (24) by interlocking ears (48) and finger hooks (50). The sliding connection of the backstop (42) to the housing (24) allows the assembly (10) to be quickly converted to a spring-biased type length adjustment device. Alternatively, if a particular application requires omission of the compression spring (40) altogether, the backstop (42) can be omitted as well, and thereby permit operation as an unbiased length adjustment device (10). This is all accomplished using the same tooling, thereby reducing the cost to manufacture the remote control assembly (10) in both spring-biased and unbiased designs.
