Winding device for winding up and unwinding a tube, cable or hose
First Claim
1. A winding device for winding and unwinding a cable comprising:
- (a) a rotatable drum in the form of a hollow cylinder around an outer circumference of which a pull-out length of the cable can be wound or unwound therefrom, by turning the rotatable drum;
(b) a hub arranged within the rotatable drum which does not turn with the rotatable drum during the winding and unwinding process;
(c) a supporting disc device which supports the cable and extends radially between the hub and the rotatable drum;
(d) a turning drive for turning the rotatable drum at least in the winding direction, wherein a cable end at the hub side is guided out of the winding device and a part of the cable is spirally arranged in a radial interstice between the rotatable drum and the hub and is supported by the supporting disc device, said part of the cable allowing a pull-out length of the cable to be wound and unwound despite a relative turning of the rotatable drum relative to the cable end at the hub side;
(e) wherein the supporting disc device is provided with at least one inner supporting disc arranged concentrically around the hub, independent of rotation of the rotatable drum and an outer supporting ring which is arranged concentrically around the inner supporting disc and turns with rotatable drum; and
(f) wherein the inner supporting disc is freely rotatable relative to the hub and relative to the rotatable drum.

Abstract
A winding device for winding up and unwinding a cable, tube or hose which comprises a cable, tube or hose section which can be wound on and unwound from the outer circumference, a cable, tube or hose section which is guided out of a hub and which does not turn with the rotatable drum and a spiral compensation length in the interstice between the rotating drum and the hub.
The compensation length is supported on a supporting disc comprising an outer supporting ring which turns with the rotatable drum and an inner supporting disc between the outer supporting ring and the hub which does not turn with the rotatable drum. Furthermore, the hub is axially subdivided into two hub parts which can be displaced relative to each other and which can be firmly joined by means of a detachable locking device. When the locking device is open, a hub part linked with a turning spring can be turned relative to the hub part linked with the compensation length of the cable, tube or hose in order to pre-span the spring as desired. The two hub parts are then firmly interlocked by means of the locking device when the desired pre-tension has been set by the corresponding turning position.
