Description

The invention relates to a hinge hinge for doors, windows and furniture with a first hinge flap with two spaced apart first rollers arranged on a common pivot axis and with a second hinge flap with a second roller arranged on the pivot axis, the second roller between the two first rollers is arranged, wherein the first rollers and the second roller are connected to each other via two pivot bolts pivotably about the pivot axis.

Hinge bands 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 fixed frame part to the movable element. For this purpose, it is basically possible to lead a suitable cable from the fixed frame via the hinge to the movable element, but a wear-free and interference-free transmission is not guaranteed with such a solution. Due to the repetitive movement, there is a risk of material fatigue and cable breakage.

the end DE 20 2014 006 683 U1 a hinge with integrated, wireless energy and signal transmission for pivotably mounted elements has become known, in which the contact is made via a slip ring body system. There are gold-coated sliding tracks radially on the one attached to the fixed element Bearing part. The cable is fed from the fixed element into the slip ring body via a grommet. On the movably mounted element there is a scanning system with pick-up springs, which are in direct contact with the grinding tracks with a defined contact pressure.

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

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

This object is achieved according to the invention in a hinge of the type described in that there is a free space between the second roller and a first roller, and that a third hinge flap is provided with a third roller, the third hinge flap resting against the first hinge flap and the third Roller is arranged in the free space on the pivot axis, with a slip ring for power and / or signal transmission being received within the second and third roller and with the pivot bolts engaging in the second or third roller in areas through the respective first roller.

In a hinge of this type, standard components can in principle be used for the first and second hinge tabs, with only a space between the second roller and a first roller being required, which is created, for example, by shortening the second roller compared to the second hinge tab . The remaining second roller and the third roller are used to hold a standard slip ring, which is inserted into the second and third roller. The slip ring is protected on the one hand and not visible from the outside on the other.

In order to mount or guide the connection cables of the slip ring, provision is preferably made for a cable opening for connecting cables of the slip ring, which is directed towards the second and third hinge tabs, to be formed in each of the second and third rolls. The connection cables from the slip ring to the respective hinge tab are routed through this respective cable opening.

It is preferably provided that the respective cable opening opens into a cable feed-through area in the second or third hinge tab. The respective connection cable can be routed to the outside, that is to say to the frame or to the movable element, through this cable feed-through area.

The groove-shaped cable lead-through area is preferably provided in the third hinge tab on the side facing away from the first hinge tab, so that the connection cables rest against the frame or movable element in the assembly position and can be continued there directly or via plugs.

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

In a further embodiment it is provided that the second and / or third hinge tab is made of plastic or die-cast metal. The two hinge tabs can then be produced using 3D printing or injection molding, for example. In this embodiment it can then be provided that semi-tubular metal caps are placed on the rollers from the outside so that the appearance of these rollers corresponds to that of the first and second metal rollers. In die casting, e.g. aluminum or zinc can be used as metals. A combination of materials is also possible.

Furthermore, it is particularly advantageously provided that the second hinge tab is designed like a comb for insertion into a hinge pocket.

In the aforementioned embodiment, it is then preferably provided that the cable lead-through area in the second hinge tab is designed as a continuous channel in a prong-shaped web. The connection cables then lead directly to the outer edge of the belt pocket and can be continued or connected from there.

A hinge for doors, windows and furniture is generally denoted by 1. The hinge 1 initially has a first hinge tab 2 with two first rollers 3 which are arranged on a common pivot axis S and spaced apart from one another. Furthermore, the hinge 1 has a second hinge tab 4 with a second roller 5 which is arranged on the pivot axis S and is arranged between the two first rollers 3 as seen in the direction of the pivot axis. There is a free space between the second roller 5 and a first roller 3, in the exemplary embodiments 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 hinge tab 4, as is the case best off Fig. 6 results.

The hinge hinge 1 also has a third hinge tab 6 with a third roller 7, the third hinge tab 6 resting against the first hinge tab 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 one first role 3.

In order to make the hinge 1 suitable for power and / or signal transmission, a slip ring 8 is accommodated within the second roller 5 and the third roller 7. For this purpose, the second roller 5 and the third roller 7 are preferably H-shaped in cross-section, as best shown in FIG Fig. 2 emerges. Through this In the assembly position, the second roller 5 and the third roller 7 form a substantially closed cylindrical receiving space 9 for the slip ring 8. Separated by the respective H-bar, the second roller 5 has a cylindrical receiving area 5a on the outside and the third roller 7 has a cylindrical receiving area 7a on. To form the hinge 1, a pivot pin 10 is inserted through the first roller in areas into the second roller 5 or third roller 7, ie into the cylindrical receiving area 5a or the cylindrical receiving area 7a.

In the second roller 5 and in the third roller 7, a respective cable opening 11, 12 directed towards the second and third hinge tabs 4, 6 for connecting cables (not shown) of the slip ring 8 is formed. These cable openings 11, 12 each open into a cable lead-through area in the second and third hinge tabs 4, 6. In the case of the third hinge tab 6, a groove-shaped cable lead-through area 13 is provided on the side facing away from the first hinge tab 2. In the case of the second hinge tab 4, the cable feed-through area in the exemplary embodiment is designed as a continuous channel 14 which runs transversely to the pivot axis S.

The second hinge tab 4 can be designed in a comb-like manner for insertion into a hinge pocket, generally designated 15, and then has prong-shaped webs 16 with an undercut for insertion and fastening in the hinge pocket 15 in a manner known per se. In this embodiment, the continuous channel 14 is then formed in a prong-shaped web 16.

To simplify the assembly and for the correct positioning of the first hinge tab 2 and the third hinge tab 6 on one another, the first hinge tab 2 and the third hinge tab 6 have corresponding fastening bores 17, 18.

The assembly of the hinge is in the Figures 9 to 11 shown:
First, the slip ring 8 is inserted into the second roller 5 of the second hinge 4 and the third roller 7 of the third hinge 6, the connecting cables (not shown) being threaded through the cable openings 11, 12 and the cable feed-through 13 as well as the channel 14. The two hinge tabs 4 and 6 are then brought together in the direction of the pivot axis S so that the two rollers 5 and 7 lie directly against one another. One of the two rollers 5, 7, in the exemplary embodiment the third roller 7, can have a tapered, hollow-peg-shaped stop 7b which engages in the cylindrical receiving area 5a of the second roller 5.

Subsequently, the preassembled second and third hinge tabs 4 and 6 are connected to the first hinge tab 2 in such a way that the two first rollers 3 encompass the second roller 5 and the third roller 7 on the outside. The two pivot pins 10 are then mounted. Each pivot pin 10 is pushed completely through the assigned first roller 3 and engages in the respective receiving area 5a or 7a of the second roller 5 or the third roller 7.

If the hinge 1 is intended to be inserted into a tape pocket 15, the second tape tab 4 is designed like a comb, as is shown in the exemplary embodiments. However, if the hinge 1 is used differently, the second hinge tab 4 can also be designed over the entire surface and have fastening bores.

The installation situation of the hinge 1 in a belt pocket 15 is shown in FIG Figures 12-14 . Since belt pouches are known per se, an explanation of the same is dispensed with at this point. As from the Figures 13 and 14 As can be seen, the continuous channel 14 of the second hinge flap 4, when this is inserted into the hinge pocket 15, opens in the sense of FIG Fig. 12 left edge of the belt pocket 15, so that the connection cables of the slip ring 8 or the like can be continued from there into a door frame or can be connected via plug connections.

Of course, the invention is not restricted to the exemplary embodiments shown. Further refinements are possible without departing from the basic idea. As mentioned above, the hinge 1 can also be used without a connection to a belt pocket 15.
