Description of the embodiment

Fig. 1 shows a sketch of an embodiment. In this case, the housing, which serves as a protective box 10 and contains the winding device, is fastened with a holder 2 to the limiting element (pile 14 ) anchored to the floor 16 . In this example, the electrical conductor is designed as an elastic, current-carrying rubber 4 to which an insulated handle 7 is fastened, which is hooked into the eyelet 15 via a current-carrying pull hook 8 . The extension length is limited by a stop plate 9 . Instead of the stop plate 9 , a contact means is also conceivable, for example in the form of an eyelet or a cable lug, which is in direct contact (ie not via the main spring 3 ) with the voltage feed means (universal bolt 1 ) and limits the extension length of the electrical conductor.

In a special case, by cutting the electrical conductor to the desired width of the passage beforehand, the main spring located in the winding device, which otherwise tries to shorten the electrical conductor, is not constantly loaded in the hooked-in state. The length adjustment is very simple and only has to be carried out once: the electrical conductor is completely unrolled from the winding device and cut shortly before the holding device (eyelet 15 ). The missing piece up to the eyelet 15 is replaced by the insulated handle 7 , in the vicinity of which there is a clamping means. Thus, the clamping device takes on the task of generating the necessary tension and the main spring 3 is relieved.

Fig. 2 shows a plan view of the inner housing having a protective cap 5. The power is supplied via the universal bolt 1 (voltage feed means) into which a hook 13 can be screwed on both sides. The main spring 3 is fastened to the universal bolt 1 and to it the elastic, current-carrying rubber 4 , which is rolled up on the reel 11 and at the end of which the insulated handle 7 hangs through the current-carrying hook 17 . In the insulated handle 7 there is a spring 6 through which a pull is exerted on the pull hook 8 . It is also conceivable that the current-carrying hook 17 and the pulling hook 8 are interchanged. It is also conceivable that the universal bolt 1 is passed through the housing so that several housings can be axially coupled to one another and / or, as described above, the electrical conductor is in direct contact with the universal bolt 1 via a contact means.

Fig. 3 shows a side view of the housing. The slip clutch disc 12 can also be seen.

Fig. 4 shows a schematic partial view of the universal pin and the current-carrying hook 13. This preferably has an external thread 20 (e.g. M5). The universal bolt 1 has an internal thread 19 (eg M5) on each side, into which the current-carrying hook 13 is screwed. The external thread 20 (eg M12) is matched to the internal thread 19 of the lock nut 18 .

All in the description, the following claims and the Features shown can be drawn individually as well be essential to the invention in any combination with one another.
