Description

The invention relates to a hinge for doors, windows and furniture with a first strap with at least one first roller and with a second strap with a second roller, the at least one first roller and the second roller being arranged on a common pivot axis and mutually about the Pivot axis are pivotally connected to each other.

Hinges of this type for doors, windows and furniture are well known. In various applications there is a need to be able to transmit power or data signals from the stationary frame part to the movable element. In principle, it is possible to run a suitable cable from the stationary frame via the hinged belt to the movable element, but such a solution does not guarantee transmission that is free of wear and tear. Due to the recurring movement, there is a risk of material fatigue and cable breakage.

Out of DE 20 2014 006 683 U1 a hinge with integrated, wireless energy and signal transmission for pivoted elements has become known, in which the contact is made via a slip ring body system. Gold-coated sliding tracks are located radially on the bearing part attached to the fixed element. The cable is fed from the fixed element into the slip ring body via a grommet. A scanning system with pick-up springs is located on the movably mounted element, which rests directly on the sliding tracks with a defined contact pressure.

However, this known strap hinge is expensive because it requires a special slip ring body system that is specially adapted to the strap hinge. In addition, corresponding changes to the hinge itself are required.

The object of the invention is to make such a hinge strip suitable for power and/or signal transmission in a structurally as simple as possible manner.

In the case of a hinge of the type described at the outset, this object is achieved according to the invention in that there is a free space between the at least one first roller and the second roller and that a third strap tab has a third roller connected to the first strap tab in the installed position and a fourth strap tab has a a fourth roller, which is connected to the second belt flap in the installed position, with the third and fourth rollers being arranged next to one another in the free space on the pivot axis and being connected to one another so that they can pivot about the pivot axis, with a slip ring inside the third and fourth roller for the current - And/or signal transmission is recorded.

With such a hinge band, standard components can in principle be used for the first and second band tabs, with only a free space having to be present between the at least one first roller of the first band tab and the second roller of the second band tab. The third and the fourth strap lugs are used to hold a standard slip ring, which is used in the third and fourth roller. The slip ring is protected on the one hand and not visible from the outside on the other. The free space can be created, for example, by shortening the at least one first and/or the second roller.

It is preferably provided that the first hinge strap has two first rollers, which, seen in the mounted position in the direction of the pivot axis, are the second, third and embrace the fourth role. This design increases the carrying capacity.

In a preferred embodiment, it is provided that two pivot bolts are provided, which are designed so long that they engage from the outside through the first or second roller in some areas into the third or fourth roller. In this way it is ensured that the rollers of the four hinge straps are aligned and centered with one another in the direction of the pivot axis.

In order to mount or guide the connecting cables of the slip ring, it is preferably provided that a cable duct for connecting cables of the slip ring is formed in the third roller and in the fourth roller in each case, directed towards the third and fourth belt flap. The connecting cables are routed from the slip ring to the respective belt flap through this respective cable duct.

In this case, it is preferably provided that the respective cable duct opens into a groove-shaped cable feedthrough area of the third or fourth strap tab. The respective connection cable can be routed to the outside, ie to the frame or to the movable element, through this groove-shaped cable bushing area.

The respective groove-shaped cable bushing area is preferably provided on the side of the third or fourth hinge tab facing away from the first or second hinge tab, so that the connecting cables rest on the frame or movable element in the installed position and can be routed there directly or via plugs.

In a further advantageous embodiment, it is provided that the third or the fourth roller has a hollow pin-shaped extension for engaging in the fourth or third roller. This reliably ensures that the third roller is centered and guided relative to the fourth roller, and there is no risk of damage caused by the slip ring tilting.

Furthermore, it is advantageously provided that the first and third hinge tabs and the second and fourth hinge tabs have corresponding fastening bores. During assembly on the frame or movable element, the respective hinge flaps are connected to one another in the correct position.

In a further embodiment, it is provided that the third and fourth strap tabs are made of plastic or die-cast metal parts. The two strap flaps can then be produced, for example, using 3D printing or injection molding. In this embodiment, it can then be provided that semi-tubular metal caps are pushed onto the rollers from the outside, so that the appearance of these rollers corresponds to that of the first and second metal rollers. Metals such as aluminum or zinc can be used in die casting. A combination of materials is also possible.

Finally, it is advantageously provided that a plain bearing is used in each of the at least one first roller and the second roller.

The invention is explained in more detail below by way of example using an embodiment.

A hinge for doors, windows and furniture is generally indicated by 1. The hinge strap 1 initially has a first strap tab 2 with two spaced-apart first rollers 3 which are arranged on a common pivot axis S. Furthermore, the hinge band 1 has a second band tab 4 with a second roller 5 arranged on the pivot axis S, which is arranged between the two first rollers 3 as viewed in the direction of the pivot axis is. There is a free space between the second roller 5 and a first roller 3, in the exemplary embodiments of the upper first roller 3, which is realized, for example, in that the height of the second roller 5 is less than the height of the associated belt flap 4, as can be seen best off 6 results.

The hinge belt 1 also has a third hinge strap 6 with a third roller 7, with the third hinge strap 6 resting against the first hinge strap 2 in the assembled position and the third roller 7 being arranged in the free space on the pivot axis S, i.e. between the second roller 5 and a first roller 3. Furthermore, the hinge strap 1 has a fourth strap lug 8 with a fourth roller 9, with the fourth strap lug 8 resting on the second strap lug 4 in the assembled position and the fourth roller 9 being arranged in the free space adjacent to the third roller 7 on the pivot axis S , ie also between the second roller 5 and a first roller 3. In the exemplary embodiment, the third roller 7 has a hollow-pin-shaped attachment 7a for engaging in the fourth roller 9.

In order to make the hinge strap 1 suitable for power and/or signal transmission, a slip ring 10 is accommodated within the third roller 7 and the fourth roller 9 .

To form the hinge strap 1, a pivot pin 11 is inserted in each case through the first roller 3 and the second roller 5 in some areas into the third roller 7 and fourth roller 9, respectively.

In the third roller 7 and in the fourth roller 9 there is in each case a cable duct 12, 13 directed towards the third and fourth belt tabs 6, 8 for connecting cables of the slip ring 10 (not shown). These cable ducts 12, 13 each open into a groove-shaped cable feed-through area 14, 15 in the third and fourth strap tabs 6, 8. The third strap tab 6 has the groove-shaped cable feed-through area 14 on the side facing away from the first strap tab 2, and the fourth strap tab 8 has the groove-shaped cable feed-through area 15 is provided on the side facing away from the second hinge tab 4 .

To simplify assembly and to position the first hinge strap 2 and the third hinge strap 6 or the second hinge strap 4 and the fourth hinge strap 8 on one another in the correct position, the first hinge strap 2 and the third hinge strap 6 have corresponding fastening bores 16, 17 and the second hinge strap 4 and the fourth hinge tab 8 has corresponding fastening bores 18, 19.

The assembly of the hinge 1 is in the Figures 14 to 17 shown:
First, the slip ring 10 is inserted into the third roller 7 of the third strap 6 and the fourth roller 9 of the fourth strap 8, with the connecting cables (not shown) being threaded through the cable ducts 12, 13 and the cable feedthrough areas 14, 15. Subsequently, the two strap flaps 6 and 8 are brought together in the direction of the pivot axis S, so that the two rollers 7 and 9 lie directly against one another, with the stop 7a in the form of a hollow pin engaging in the fourth roller 9 .

Then slide bearings 20 are preferably inserted into the first two rollers 3 and the second roller 5 ( 15 ) and the two belt flaps 2 and 4 positioned next to each other so that the rollers 3 and 5 are on the pivot axis ( 16 ). In this position, the two hinge straps 2 and 4 are pressed into the preassembled hinge straps 6 and 8 so that the third roller 7 and the fourth roller 9 are in the free space between a first roller 3 and the second roller 5 on the pivot axis S. The two pivot bolts 11 are then inserted, after which the hinge belt 1 is fully assembled ( 17 ).

After the hinge strap 1 has been installed, the connecting cables of the slip ring 10 are fed into a door frame and a door leaf or the like, or connected via plug-in connections.

Of course, the invention is not limited to the illustrated embodiments. Further refinements are possible without departing from the basic idea. Thus, the hinge strap 1 can also have only a first roller 3 on the first strap tab 2 , namely the one that is in contact with the third roller 7 .
