A novel device is provided hereto for automatically adjusting the length of the sheath of a bowden cable, such bowden cable being capable of transmitting substantial forces. The bowden-cable sheath terminates in a sleeve with a stepped outside diameter so that 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 which rest on the large diameter of the sleeve and which, upon displacement of the sleeve out of the housing, sequentially drop onto the small sleeve diameter. The dropped panes extend the sheath each time by their thickness. Such spacer panes form the support, between the sleeve collar and the housing inside wall, for the force exerted on the bowden cable. In a special embodiment, the device 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 the sleeve back to its original position. This embodiment is closed on all sides and denies access to water, dirt, etc. |
