The invention further relates to a fitting arrangement with such a bearing unit and a window, a door or the like with such a fitting arrangement.

A storage unit described above is from the EP 1 936 084 A2 known. A bearing element of the known bearing unit is supported between a bearing bush and a housing-shaped fastening element. The collar of the bearing element is held axially in the bearing unit. When a wing is raised and then lowered, which is connected to the bearing unit via its wing frame, the bearing element in the bearing bush is not tilted due to the prevention of the axial movement of the bearing element.

Furthermore, the EP 1 932 992 A2 an captive fastening of a support bolt to a bearing bush. For this purpose, the support bolt has a circumferential groove in which a pin engages.

Also from the DE 20 2008 004 933 U1 it has become known to secure a support bolt to a bearing bush by means of a locking pin.

Furthermore, the EP 1 054 126 A1 securing a supporting bolt to a bearing bush using a locking ring.

After all, it's out of the DE 202 10 361 U1 become known to provide a locking bush for a supporting bolt, the supporting bolt is screwed into a bearing bush and a shoulder of the supporting bolt is supported on the locking bush.

In contrast, the present invention is based on the object of creating a bearing unit with a securing of the bearing element which is both compact and easy to assemble.

This object is achieved by a storage unit according to claim 1. The subclaims represent preferred embodiments.

1. a) Einen Tragbolzen, der mit dem Ausstellarm verbindbar ist, wobei der Tragbolzen ein erstes Gewinde aufweist;
2. b) ein durch ein Werkzeug drehbares Lagerelement mit einem zweiten Gewinde, das in das erste Gewinde eingreift;
3. c) eine Lagerbüchse, in der das Lagerelement zumindest teilweise aufgenommen ist;
4. d) einen axial in einer Höhe umlaufenden, radial zur Längsachse des Lagerelements vorspringenden Kragen, der sich in einer ersten axialen Richtung des Lagerelements mittelbar oder unmittelbar an der Lagerbüchse abstützt;

wobei sich der Kragen entgegen der ersten axialen Richtung an einer Hülse der Lagereinheit abstützt, die in die Lagerbüchse eingesetzt ist.The object according to the invention is thus achieved by a bearing unit for height adjustment of a fastening element which can be fastened to a sash frame relative to an extension arm, the bearing unit having the following:

1. a) a support bolt which can be connected to the deployment arm, the support bolt having a first thread;
2. b) a bearing element rotatable by a tool with a second thread, which engages in the first thread;
3. c) a bearing bush in which the bearing element is at least partially received;
4. d) a collar which projects axially at a height and projects radially to the longitudinal axis of the bearing element and which is supported indirectly or directly on the bearing bush in a first axial direction of the bearing element;

wherein the collar is supported against the first axial direction on a sleeve of the bearing unit, which is inserted into the bearing bush.

The sleeve of the storage unit enables easy mounting of the storage unit. The sleeve can be inserted into the bearing bush before mounting the bearing element. To secure the bearing element, no pin or the like has to be subsequently inserted into the bearing bush. At the same time, the sleeve takes up little space and thus enables a very compact design of the bearing unit. The sleeve holds the collar of the bearing element axially essentially immovably on the bearing bush. The sleeve preferably holds the collar with a clearance fit on the bearing bush. When the wing is raised and lowered, there can no longer be a large axial movement of the bearing element and thus a tilting of the bearing element.

The first axial direction preferably runs counter to the load direction of the bearing unit, ie counter to the direction in which the weight of a Wing presses in the operating state of the storage unit on the storage unit.

The first thread of the support bolt is preferably in the form of an internal thread, the second thread of the bearing element is preferably in the form of an external thread.

The bearing element is further preferably designed in the form of a screw, the collar being designed in an annular manner on the screw head.

The collar is axially circumferential at a height. In other words, in contrast to a thread, the collar is formed axially in a single plane.

The diameter of the collar is preferably 1.2 times to 3 times the diameter, in particular 1.5 times to 2 times the diameter of the second thread. This achieves a stable but space-saving design of the collar.

The sleeve can be made of plastic. The sleeve is preferably made of aluminum in order to have high stability and stability.

The sleeve is preferably at least partially elastic.

The sleeve is particularly preferably at least partially slotted. This makes it easy to assemble. The sleeve can have an essentially axially extending slot that completely cleaves the sleeve. Alternatively or in addition to this, the sleeve can have at least one slot which only cuts into the sleeve. The sleeve preferably has a plurality of slots. The formation of at least one slot on the sleeve is particularly preferred if the sleeve is made of plastic.

Assembly can also be made easier if the sleeve is inserted into the bearing bush with a clearance fit.

The sleeve can have an axially extending, radially inward-pointing groove for at least partially receiving the collar in order to secure the collar to the sleeve.

Alternatively or in addition to this, the sleeve can have at least one radially inwardly projecting projection on which the collar is supported.

The sleeve preferably has a plurality of projections projecting radially inwards, on which the collar is supported. By forming multiple protrusions, i.e. an interruption of a single circumferential projection, the elasticity of the projections is maintained, so that the collar can be easily slipped over the projections when mounting the bearing unit.

In a particularly preferred embodiment of the invention, slots are formed between the projections.

Particularly preferably, at least one protrusion, in particular all protrusions, has a bevel in order to facilitate the assembly of the collar on the sleeve.

The slope (s) preferably have a narrowing diameter in the first axial direction. In other words, when viewed radially, the clear opening of the sleeve is reduced by the bevel (s) in the first axial direction. As a result, the collar of the bearing element can be pushed slightly over the projection or the projections during its assembly, but can only be pulled back again with difficulty, so that the collar is firmly seated in the region of the projection or the projections. After assembly of the bearing unit, the sleeve and collar are preferably not separable without being destroyed.

In the first axial direction, the sleeve can have a spacing projection, which extends away from at least one projection and whose axial length essentially corresponds to the axial length of the collar. In this way, a defined fit of the collar is achieved relative to the projection or the projections.

The spacing projection can be formed in one part or in several parts. The spacing projection is preferably designed to run radially around the longitudinal axis of the sleeve.

In a further embodiment of the invention, the collar is supported on the bearing bush in the first axial direction via an axial bearing of the bearing unit. The axial bearing enables a particularly low-friction rotation of the bearing element relative to the bearing bush.

In a particularly preferred embodiment of the invention, the support bolt is supported directly or indirectly, in particular directly, on the bearing bush via a first radial bearing of the bearing unit. The first radial bearing is preferably designed in the form of a needle bearing.

A particularly stable design of the bearing unit is achieved if the supporting bolt continues to be directly or indirectly, in particular directly, via a second radial bearing on the Bearing bush supports. The second radial bearing is preferably designed in the form of a needle bearing.

The radial bearing (s) and / or the axial bearing are preferably pressed in the bearing bush.

The support bolt can have a spacer collar which serves in the first axial direction as an adjustment stop with respect to the first radial bearing and against the first axial direction as an adjustment stop with respect to the second radial bearing.

The sleeve preferably extends in the first axial direction between the first radial bearing and the axial bearing.

More preferably, the bearing unit has a rotation lock between the first thread and the second thread in order to prevent the bearing unit from being displaced during the opening and closing movements of the wing. The first thread and / or the second thread can have a recess in which a rotation lock element is arranged, which has a lower hardness than the bearing element and / or the support element.

The anti-rotation element is preferably designed in the form of a cord, in particular a perlon cord.

The object according to the invention is further achieved by a fitting arrangement for connecting a casement to a fixed frame of a window, a door or the like, the fitting arrangement having an opening arm, a fastening element and a bearing unit described above.

The fastening element is preferably designed in the form of a housing in which the bearing unit is received.

The object according to the invention is finally achieved by a window, a door or the like with a sliding wing and a previously described fitting arrangement.

The fitting arrangement is preferably mounted in the assembled state of the window, the door or the like in the area of the underside of the sash, so that the sash, via the fitting arrangement - which contains the bearing unit - directly or indirectly on a fixed frame of the window, the door or the like supports.
