"Hinge joint or band, especially object band"

The invention relates to a hinge joint or hinge, in particular object hinge, with a pivot pin, a horizontal sliding bearing and mechanical compensating bearings.

Object hinges are used in a variety of ways to fasten heavily used, heavy furniture doors, door or window sashes, etc. To improve the turning properties and to compensate for certain assembly inaccuracies, it is known to equip such object hinges with invisible, permanently installed ball bearings and interacting horizontal plain bearings.

The disadvantage of the known ball bearings is that they are relatively sensitive to impact and expensive. The balls can be damaged relatively easily, especially under high pressure forces, and if the belt centers are not aligned, the bearings can jam.

The object of the present invention is therefore to create an inexpensive and shock-resistant solution with which, while maintaining the existing ball-bearing object belts, jamming of the bearings when the belt centers are not aligned is avoided.

This object is achieved according to the invention in that

the mechanical compensating bearings are designed as dry plain bearings with a ball socket and a spherical disk.

By installing and using dry plain bearings with ball socket and disk according to the invention, known from general mechanical engineering, a simple design of hinge joints or hinges is made available that can withstand high mechanical loads and avoids the installation of expensive and relatively shock-sensitive ball bearings. The compensating bearings arranged on both sides of the horizontal plain bearing arranged in the object hinge also tolerate a non-100% vertical installation of the respective object hinge for fastening heavily used door and window sashes etc. In conjunction with the horizontal plain bearing, they always ensure that the respective components can be opened and closed easily without the risk of the individual hinge joints or hinges becoming jammed or jammed.

The ball disc or ball socket is designed as an integral part of the horizontal plain bearing. This eliminates the need for an additional, loose ball disc, which simplifies the installation of the object belt.

The dry plain bearings are designed as circular cylindrical 360° bearings. This enables a particularly high mechanical load capacity

reached.

In order to achieve particularly smooth movement of the hinge joint or hinge, the invention also provides that the ball sockets and discs are made of a different material than the pivot pins, the horizontal sliding bearing and the other parts of the hinge. This reduces the frictional resistance between the hinge parts that are adjacent to one another and can be rotated against one another.

It is advantageous if the running surfaces of the ball sockets and discs are hardened. This further increases the shock resistance and smooth running of the hinge joint or band.

The invention also provides that the horizontal plain bearing is made of a particularly strong, rust-proof material, in particular brass. This material, made of copper and zinc, has particularly good strength properties due to the solid solution hardening, which is particularly desirable in the case of high pressure and rotational stress.

It is also intended that the surfaces of the horizontal plain bearing and/or the running surfaces of the ball sockets and discs are coated or, for example, covered with a plastic.

steamed. This further increases the smooth running.

Finally, the invention also provides that the horizontal plain bearing has at least one vertical lubrication groove. This ensures constant lubrication of the hinge joint or band. Since the rotation range of such joints is approximately 100° to 120°, preferably three vertical lubrication grooves are provided, arranged at the same distance from one another, in order to evenly lubricate the entire surface of the horizontal plain bearing.

The invention is explained in more detail below using the drawing as an example. This shows:

In the examples shown, an object hinge generally designated 1 has a one-piece sash hinge 2 designed as a built-in hinge and a

designed one-piece frame hinge 3 and a hinge designated 4. The sash hinge 2 has a support plate 5, which can be fastened to a base element of a piece of furniture, a door leaf, a window leaf or the like by means of screw elements (not shown in detail) through the openings 6. The frame hinge 3 is connected to an adjustable wooden construction (VHK) (not shown in detail) in the frame by means of toothed pins 7. The sash hinge 2 and the frame hinge 3 are held together in the installed position by means of a pivot pin 8, which is fixed at its lower free end 9 by a threaded knob 10. A horizontal sliding bearing 12 with a vertical lubrication groove 18 is arranged within the roller 11 of the frame hinge 3, which encloses the pivot pin 8. The horizontal sliding bearing 12 is rotatably mounted in the compensating bearings 13 arranged above and below the horizontal sliding bearing 12 on the pivot pin 8. These are designed in two parts in the embodiment shown and each consist of a ball socket 14 and a ball disk 15, with the ball sockets 14 being arranged with a press fit in the roller 11 of the frame band 3.

The mechanical compensation bearings 13 are designed as circular cylindrical 360° bearings in the embodiment shown and can, although this is not absolutely necessary, be made of the same material as the horizontal sliding bearings.

bearing 12, but made of a different material than the pivot pin 8 and the other parts of the object band 1, in order to increase the smooth running.

If the object belt 1 is not completely vertical in the respective installation position, a slight offset can be compensated by the dry sliding bearings 13 according to the invention in conjunction with the horizontal sliding bearing 12, which is indicated by the arrows 16-16 and 17-17 in Figure 1. In this case, the spherical disk 15 deviates slightly outwards in one direction in the ball socket 14, in which it is held movable, and in the case of the two opposing compensation bearings 13 in each case in a different direction.

Of course, the present invention^ is not limited to the embodiment shown. Other embodiments are possible without departing from the basic idea of the invention. The only important thing is that instead of a known ball bearing, a simple mechanical compensating bearing 13 with a ball socket 14 and a spherical disk is provided.
