ABSTRACT:
An apparatus to adjust the length of the sheath of a bowden cable and capable of transmitting substantial forces. The bowden cable sheath terminates into a sleeve with a stepped outside diameter whereby it can be inserted into a structure fixed housing against the force of a compression spring. The housing contains a set of spacer panes which are spring-loaded and rest on the large diameter of the sleeve and which upon displacement of the sleeve out of the housing sequentially drop on the small sleeve diameter. The dropped panes extend the sheath each time by their thickness and between the sleeve collar and the housing inside wall form the support for the force exerted on the bowden cable. In a special embodiment, the apparatus is equipped with mechanical means accessible from the outside which when actuated will reset the already dropped spacer panes into their initial positions. Another embodiment offers the possibility to reset the spacer panes into their initial positions by shaping the sleeve so asymmetrically that these spacer panes can be returned to their initial positions by a 90.degree. rotation of the sleeve and by displacing this sleeve into the end fitting and rotating back the sleeve. This embodiment is characterized by being close on all sides and denies access to water, dirt, etc.
