SUPPLY SYSTEM FOR AN ELECTRICAL LINE, IN PARTICULAR FOR A CHARGING CABLE FOR AN ELECTRIC VEHICLE
A supply system for an electrical line, in particular for a cable for charging electric vehicles, comprising at least one cable store, wherein the cable store has a plurality of pulleys which are arranged in at least two pulley blocks in such a manner that a cable can be threaded into the pulley blocks in several windings, wherein a first pulley block and a second pulley block can be displaced relative to one another, at least one of the first and second pulley blocks is arranged on a linearly guided, displaceable pulley block carrier, and the first and the second pulley blocks can be moved on top of one another against a restoring force, wherein the supply system is in particular characterised in that the pulley block carrier is guided on and/or in at least one guide profile which is designed as a guide rail or forms at least one guide rail, the pulley block carrier is designed as a profile that is complementary to the guide profile, and the guide profile and the profile of the pulley block carrier engage in one another in a form-fitting manner such that an anti-tilt and anti-turn linear guiding of the pulley block carrier is effected in the direction of displacement.

17 . A supply system for an electrical line, in particular for a cable for charging electric vehicles, comprising at least one cable store, wherein the cable store comprises a plurality of pulleys, which are arranged in at least two pulley blocks such that a cable can be reeved into the pulley blocks in one or more windings, wherein a first pulley block and a second pulley block are displaceable relative to each other, at least one of the first and second pulley blocks is arranged on a linearly guided, displaceable pulley block carrier, and the first and the second pulley block are movable towards each other against a restoring force,
wherein the pulley block carrier is guided on and/or in at least one guide profile which is formed as a guide rail or forms at least one guide rail, in that the pulley block carrier is formed as a profile that is complementary to the guide profile and in that the guide profile and the profile of the pulley block carrier engage in each other in a positive-locking manner such that an anti-tilt and anti-twist linear guidance of the pulley block carrier is brought about in the displacement direction, wherein the guide profile is formed as a central guide column which can be installed in a self-supporting manner, and which is formed as a supporting component part for both pulley block carriers, the cable laid thereon as well as the retracting mechanism, and in that the second pulley block is fastened on one side and cantilevered on the pulley block carrier and in that at least one pulley block has in each case multiple pulleys arranged distributed in an arc shape over a circular arc around a deflection axis and at least one of the first and second pulley blocks is arranged and held on the displaceable pulley block carrier.
18 . The supply system according to claim 17 , wherein the first pulley block is arranged fixed in position and in that the second pulley block is displaceable with respect to the first pulley block on the pulley block carrier.
19 . The supply system according to claim 17 , wherein the pulley block carrier is formed as a carriage which is supported on guide bars or profiled belts of the guide profile via guide rollers and/or via sliding guides.
20 . The supply system according to claim 17 , wherein the guide profile has at least one hole pattern and/or tooth pattern continuing at least in the displacement direction of the pulley block carrier as part of a return stop acting against the restoring force.
21 . The supply system according to claim 20 , wherein the return stop is formed as a retaining pawl.
22 . The supply system according to claim 20 , wherein, in the displacement direction of the pulley block carrier, the return stop comprises a plurality of discrete locking positions and a plurality of discrete release positions provided between the locking positions for at least one pawl, which can be deflected against a spring force and which is preferably mounted deflectable against a spring force on the pulley block carrier.
23 . The supply system according to claim 17 , wherein the guide profile comprises at least one hole pattern extending in the displacement direction of the pulley block carrier, in that the hole pattern comprises a plurality of first smaller holes which each form a locking position for a pawl engaging in them and in that the hole pattern comprises a plurality of second larger holes which each form a release position for a pawl dipping into them.
24 . The supply system according to claim 20 , wherein the return stop comprises at least one pawl which has at least one locking tooth and at least one sliding tooth, wherein the locking tooth is formed for blocking engagement in the hole pattern and the sliding tooth is arranged offset parallel to a pivot axis of the pawl and formed as a pivot limit stop for the pawl.
