DE3916400A1 - Cable reel with incorporated radio appts. - insertable into reel and does not co-rotate on extension cable winding - Google Patents

Abstract

The radio receiver can be inserted into a cable reel in such a manner that it does not rotate with the reel on (un)winding of the extension cable. The radio receiver can be pulled out from the reel, e.g. during work which result in the radio receiver damaging such as during heavy dust formation. The mechanism for rotating the cable reel serves simultaneously as a plug for current supply, as well as a parking brake. The reel is typically mounted on four axes. A box with material, e.g. dowels, can be also inserted into the cable reel. ADVANTAGE - No need for batteries. Protection of radio receiver from damage.

Description

The invention relates to a cable drum in which a radio is turned can be stuck.

It is known that more and more construction workers are at work Listen to the radio. But since the operation of the radio on batteries if the duration is too expensive, a network connection is preferred. However, this has the consequence that an additional expenditure of time is operated, e.g. B. are in the assembly of radiators drilled the mounting holes for the radiator in a room and this is installed, the heating technician changes with the Cable drum and the drill in the next room and then go the same way to get the radio, to place it again and turn the plug into the ver insert the extension drum. The radio is still in the drum is protected from damage.

The invention has for its object the more time to avoid wall and the radio directly with the power source connect to save the high cost of batteries, as well better protect the radio from damage.

This is inventively solved in that the cable stream mel is not mounted on an axle as usual, but on four bearing rollers, the axes of which also serve as fasteners serve for the radio, whereby at the point at which nor times the sockets are attached, now through the square arrangement of the axes creates a round cavity,  in which a radio built for this purpose is inserted can.

On one side of the cable drum comes the speaker, on the other hand, the controls appear. The sockets can be above or below the speaker be appropriate to provide additional protection for the radio when moving around fall to offer the drum.

If the cable drum is used for work involving a dam damage to the radio (e.g. dust), this can be pulled out using an attached handle. It can also be used at any time like a normal radio the, the side of the controls as a footprint can serve.

The handle for rotating the drum also serves as Plug for the power supply of the radio, as this is about Cable is connected to the extension cable. Is the ver extension cable rolled up to the correct length, the Handle pressed into the radio and thus the Stromver ensures guaranteed and is also a festival at the same time Parking brake against unwanted rolling up of the drum. A required antenna could be under the handle of the radio to be brought. The drawing shows four views.

Fig. 1 shows the cable drum with the radio inserted from the side of the speaker.

Fig. 2 shows the back of the cable drum with the operation buttons of the radio.

Fig. 3 shows in section a part of the drum and an inserted radio in any original size.

Fig. 4 shows an exploded view of the cable drum with the radio (drum in section).

A cable drum ( 1 ) is mounted on four rollers ( 2 ), the four axes ( 3 ) of which are connected to the support structure ( 4 ) of the drum ( 1 ). The four axes ( 3 ) also serve to fasten the radio ( 6 ) using two screws ( 5 ) (it could also be a pressure fastener). The roller bearings ( 2 ) are secured on the left with a snap ring ( 7 ) and on the right by increasing the diameter ( 8 ) of the axle ( 3 ) against slipping. The molded edges ( 9 ) of the drum ( 1 ) ensure that it is guided. The square arrangement of the four axes ( 3 ) creates a round cavity ( 10 ) in the center of the drum ( 1 ) (where the sockets are usually), into which a radio ( 6 ) built for this purpose is attached by means of a handle ( 11 ) can be inserted.

If the radio ( 6 ) is inserted, the controls ( 13 ) and the front ( 14 ) of the loudspeakers ( 15 ) appear on the back ( 12 ) of the cable drum. The sockets ( 16 ) could be inserted at the top and bottom (or on the side).

The handle ( 17 ) for rotating the drum also serves as a connector for the power supply to the radio ( 6 ), since it is connected to the extension cable ( 19 ) with the required cables ( 18 ). The handle ( 17 ) is attached to the drum ( 1 ) so that it can be moved. If the extension cable ( 19 ) is rolled up to the desired length, the handle ( 17 ) with the built-in plug ( 20 ) is inserted into the radio ( 6 ) (the Ge plug connector in the radio is not shown in the drawing) and the power connection is made; at the same time the drum ( 1 ) is blocked against unwanted rolling up.

An antenna could be accommodated in the handle ( 1 ) of the radio ( 6 ).

Claims (6)

1. Cable drum with built-in radio, characterized in that a radio can be inserted into a cable drum. 2. Cable drum according to claim 1, characterized, that the radio turns on when the extension cable is rolled up not turning. 3. Cable drum according to claim 1, characterized, that the radio can be pulled out of the drum (e.g. for work that would result in damage, e.g. B. strong dust). 4. Cable drum according to claim 1, characterized, that the device for rotating the cable drum is also the same early as a plug for the power supply and parking brake serves. 5. Cable drum according to claim 1, characterized, that the drum is supported on four axes. 6. Cable drum according to claim 1, characterized, that a material box is inserted into the cable drum can (e.g. dowel box).
