<p>A cable drum for the automatic rewinding of a cable in which two separate winding areas are located on a shaft loaded with the force of a restoring spring. The cable is fixed by a slot in the winding areas in a disc-shaped separating wall which is common to the winding areas. The shaft is perpendicular to a rotary disc or bushing of a two-part spring housing and engages the rotary disc or bushing in a form-locked manner. The shaft is held in a bearing of a stationary part of the spring housing. This stationary part holds feed-out guides for the two ends of the cable. The stationary part of the spring housing, furthermore, is expanded to form a cylindrical wall which bounds the winding areas on a side and partially extending over the cable drum discs fixed on the shaft. A cover is detachably fastened on this cylindrical wall and extends over the remaining portion of the cable drum discs. The cylindrical wall contains the feed-out guide which is open on the face side for one cable end, and the cover contains the feed-out guide for the other cable end. The shaft, moreover, engages the bushing in a form-locked manner, and the bushing is connected with one end of the spring located in the spring housing and is rotatably mounted in the stationary part which is attached to the other end of the spring. The spring may be in the form of a spiral spring.</p> |
