Description

The The invention relates to a carrying device according to the preamble of Claim 1.

such Devices are known in various designs.

At the citation DE 34 16 823 A1 it is a genus-like support device, but explicitly has no transport safety. The adjustable (countered) nuts 23 . 24 in conjunction with the (stop) element 25 are used only to set a limit of the support arm 2 (Outrigger) upwards. Although it is on page 9, paragraph 1 of the speech, if necessary, the height adjustment range to the value 0 to limit, ie that the support arm 2 (Boom) is fixed rigidly in a certain position. However, this can only be seen as a special case in an operating condition and not as a transport security.

Of the Invention is based on the object, a generic same device to create, in the transport security in a simple way yet has another function.

Is solved this object according to the characterizing part of claim 1. More Advantageous developments of the invention go to claim 1 from the dependent claims out.

The Invention is based on an embodiment described in more detail.

It shows:

1 in a side view of a part of the support device with an activated transport lock;

2 in a side view after the 1 the entire carrying device;

3 in a plan view of a part of the support device according to the 1 ;

4 a section IV-IV after the 3 ;

5 a side view like after 1 However, the support arm in an upwardly limited height position, as well

6 a side view like after 1 However, the support arm in a limited downward height position.

1 shows a part of a support device 1 with a continuously height-adjustable support arm 2 with a counter-force device 3 for continuously compensating a mass of a supporting object 4 ( 2 ) in dependence of a set carrying height, wherein the support arm 2 with an upper and a lower arm leg 5 . 6 constructed in the manner of a parallelogram and on both sides in each case a joint part 7 ( 2 ) 8th has, and that the first joint part 7 with a fastening device 9 ( 2 ) and the second hinge part 8th with a holding device 10 for carrying the object 4 is provided, wherein for a transport and for mounting the horizontally fixed device 1 the counter-force device 3 ( 2 ) by means of a transport lock 11 is disabled, the second hinge part 8th with the transport lock 11 is provided. The transport security 11 has such adjustable, axially connected stop pin 12 on that in a first position 13 as transport security 11 the support arm 2 block and in a second position 14 the blocking of the support arm 2 pick up and with the stop pins 12 the support arm 2 Block to an upwardly limited height position.

The hinge part 8th (as well as the joint part 7 / 2 ) has two parallel side panels arranged side by side 15 on that with a connector 16 are firmly connected. The hinge part 8th is by means of joints 17 . 18 with the two arms of the arm 5 . 6 of the support arm 2 connected. The two side parts 15 are each with a slot guide 19 provided for guiding the stop pins 12 that of a threaded spindle drive 20 between two positions 13 . 14 can be moved, wherein the connecting part 16 a rotation recording 21 for a threaded spindle 22 that forms with a threaded nut part 23 and the stop pin disposed thereon 12 is adjustably connected. In the first position 13 causes the interaction of the stop pin 12 and a top / top edge 24 in the upper end area 25 of the upper leg of the arm 5 over the joint 17 a Verdrehblockierung upwards, whereby a transport locking function is achieved.

The two slot guides 19 are arranged obliquely to the left above and dimensioned that at horizontally held position of the support arm 2 the stop pins 12 in a second position 14 a predetermined distance X to the first position 13 and a predetermined distance Y to the top 24 of the upper leg of the arm 5 exhibit.

In the 2 is the complete carrying device 1 shown, in which case the holding device 10 with a dashed line indicated supporting object 4 (For example, a medical device or a drying hood) provided and the fastening device 9 at a wall indicated by dashed lines 26 connected is.

A corresponding plan view of the support device 1 after 1 is in the 3 shown. This is in particular the interaction of the stop pin 12 and the top 24 in the upper end area 25 of the upper leg of the arm 5 closer. The holding device 10 is designed to carry out lines not shown hollow.

The 4 shows after a section IV-IV after the 3 the threaded spindle drive 20 that's from the threaded spindle 22 , Threaded nut part 23 , Shooting 21 , Connecting part 16 and a screwdriver holder 27 consists.

In the 5 is the arm 2 shown in an upwardly limited position, which was achieved in that the stop pin 12 from the first position 13 ( 1 ) in the second position 14 were adjusted by turning the threaded spindle 22 by means of a screwdriver, not shown. Also in this position take the stop pins 12 about the same stop point as in the transport or mounting fuse position.

In the 6 is the arm 2 shown in a limited down position. In this position take the stop pins 12 a stop point shifted to the left on the upper side 24 of the upper leg of the arm 5 one. An additional function is given by the fact that the stop pin 12 are arranged so that they support arm 2 also in the second position 14 to block down to a limited height.

The combined transport protection 11 / Height adjustment works very well from the front of the carrier 1 to adjust. If necessary (for example, for safety reasons), the screwdriver receptacle 27 be closed with a stopper, not shown, to prevent unauthorized rotation or adjustment.

In the context of the invention, instead of the threaded spindle drive 20 for the stop pins 12 for example, a corresponding lever arrangement or other Verstellmachanismus for adjusting the stop pins 12 from a corresponding first position 13 in a corresponding second position 14 be provided.
