[0002] Fishtape and / or rope pulling tools that work manually according to the principle of cable drum are known. Here, pulling means is usually fixed and cannot be loosened and connected with cable drum or tool. Summary of the invention

[0003] The invention is based on a cable winding device having a transport unit for transporting a traction device, in particular a fish tape, which is provided for winding a cable into an empty tube, and having at least one traction device support unit, in particular a traction device drum, for supporting the traction device, preferably at least mostly wrapped.

[0004] The invention proposes that the traction means has a coupling unit which is provided for detachable, in particular direct, coupling to the traction means, for example when the traction means is replaced.

[0005] The configuration of the cable retractor according to the invention allows for greater flexibility in use, since advantageously a plurality of different pulling means can be connected to one cable retractor. Furthermore, depending on the application, pulling means with different bending stiffnesses or made of different materials can advantageously be used. Furthermore, since only different pulling means can be purchased for one cable retractor and the purchase of a plurality of cable retractors or pulling means reels can be dispensed with, costs can advantageously be saved for the user.

The cable retraction device is particularly at least configured to be used for retracting traction devices such as threaders or ropes. In addition, the cable retraction device can also be configured to be used to output and / or push traction devices such as threaders or ropes.

Traction devices, especially threaders, ropes, etc. can have a circular cross-section, an elliptical cross-section, a polygonal cross-section or a flat belt cross-section. In particular, the traction device can be constructed in multiple pieces, for example, as a braided wire or a stranded wire composed of a single wire bundle.

[0007] The transport unit can be configured to transport the traction means in two mutually opposite transport directions. The transport unit is in particular configured at least to pull the traction means. In addition, the transport unit can also be configured to push the traction means. In general, the transport unit is configured not only to pull but also to push the traction means. Particularly preferably, the transport unit is configured to preferably wind and / or unwind the traction means in a traction means support unit, in particular a traction means reel, onto a support shaft of the traction means support unit. Preferably, the transport unit comprises at least one drive unit. Preferably, the drive unit is configured to generate a drive force, which winds and / or unwinds the traction means in the traction means support unit, in particular a traction means reel, onto a support shaft of the traction means support unit.

Preferably, at least a large part of the traction means is enclosed by the housing unit, in particular, the housing unit at least partially carries the traction means. The housing unit at least partially carries the transport unit, in particular, this is to be understood as meaning that at least 50%, preferably at least 75% and advantageously at least 90% of the total weight of the transport unit acts on the housing unit.

[0011] In this context, "releasable" is to be understood as meaning, in particular, "detachable without damage". In particular, the coupling of the coupling unit can be releasable, in particular detachable without damage, by means of a tool, in particular by means of a hexagonal wrench, a screwdriver and / or a tool specially developed for the coupling unit and / or manually (without tools).

[0012] It is further proposed that the transport unit is configured to provide a coupling mode, which is arranged to provide access to the coupling unit, in particular to enable at least replacement of the traction means. This advantageously makes it possible to provide access to the coupling unit as simply as possible. In addition, an accidental release of the traction means during operation of the cable retraction device can be advantageously prevented, and in addition, contamination of the coupling unit, in particular the coupling point, can be advantageously reduced. Preferably, access to the coupling unit is only provided in the coupling mode, in particular for replacement of the traction means. Particularly preferably, the control of the transport unit can be adjusted manually, preferably by a user and / or automatically, preferably by a control and / or regulating unit.
