Abstract
Abstract A motion transmitting remote control assembly (10, 110) of the type for transmitting motion in a curved path. The assembly (10, 110) includes a conduit (14, 114) having an end fitting (16, 118) thereon adapted for mounting to a support structure. A tubular member (22, 122) is connected to and extends from the end fitting (16, 118). A telescoping member (25, 125) is slideably supported by the tubular member (22, 122). A coupling member (30, 130) fixedly supports the telescoping member (25, 125) and defines a channel (34, 134) therein. A core element (26, 126) extends through the conduit (14, 114) and the tubular member (22, 122) and into the channel (34, 134) of the coupling member (30, 130). A slug (46, 146) is disposed on the end of the core element (26, 126) and is received in the channel (34, 134) to define a lost motion connection between the core element (26, 126) and the coupling member ( 30, 130). The lost motion connection allows relative longitudinal movement between the core element (26, 126) and coupling member (30, 130) along a predetermined overlapping length while simultaneously allowing for relative telescoping movement between the coupling member (30, 130) and the tubular member (22, 122) along the predetermined length.
