Storage space for supply cables in cable reels For the orderly storage of conventional electrical cables of greater lengths, portable cable reels have been known for a long time, which are mainly used for manual purposes and, by incorporating several sockets, simultaneously serve as a distribution point, while the unreelable cable end is equipped with a plug.

In contrast to this, however, the market is increasingly demanding such cable drums, in which the plug remains with the drum and a coupling on the unwindable Cable end is located (e.g. as a supply line for lawn mowers). ,} In order to also remove the short supply cable (which must necessarily be attached) to the

The sense of a cable drum to be properly accommodated are already the following Constructions known in which the supply line

a) is wound up in front of the cable drum by means of two hooks,

b) is wound onto a second, upstream, small drum, or

c) is placed in a cavity around the front plate of the Cable drum is running (see patent specification No. 1088571).

In contrast to the aforementioned possibilities, my development is straightened out the use of the cable drum interior by placing the drum front panel (2) is cut out (i.e. a hole shows) that the short connecting cable with plug Can be "stuffed in" and prevented from falling out by a small rim will.

For this purpose, the drum core (1) must be designed so that the rotary hub represents the cable drum, which runs on the axle stub (4a) of the support frame (4) and at the same time the attachment of the rear (3) and front drum plate (2) serves so that the latter no longer have a wheel hub function.

A variant, in particular to make it easier to insert the supply line, is available a change in the plate cutout to the effect that the edge of the hole with the Inner wall of the drum core (1) is flush and tooth-like projections (5) prevent the supply line from falling out.

As a further variant, in particular for manual-mechanical rolling up of the supply cable (instead of plugging it into the drum core), the installation of a second, smaller and rotatable cable drum in the drum core should be considered. Due to the free storage on the extended stub axle (6) of the built-in drum in the Axle stub (4a) of the tubular steel support frame and the rear plate of this built-in drum (7) on the drum core, there is free rotation, as well as pulling out and pushing in guaranteed. The front plate of the built-in drum with its axis would depend on the production process (8) with the rear drum part, the rear plate (7) plugged together and screwed together, splinted, glued or riveted.

After inserting the plug into the retaining clip (9), the supply cable needs its implementation from the drum core outside to the interior just behind the front The drum plate (2) must lie on the built-in drum by simply turning it - in front of the plate be rolled up and the built-in drum can be pushed into the drum core. A complete pulling out of the installation drum, as well as a risk of injury to the electrical cable at the feed-through point in the drum, is attached by locking projections the mounting bushes of the drum core voetidak. prevented.
