EP0340455B2 - Pivot bearing for the connection of two wings of a window, door or the like - Google Patents

Abstract

So that two wings (1, 2) of a window, door or the like, rotationally connected to one another via at least one pivot bearing, especially two wings of a sliding and folding door or sliding and folding window, can be aligned exactly with one another in the horizontal direction or readjusted, there being fixed to a first wing (1) a first bearing part (7) and to a second wing (2) a second bearing part (8) which are connected to one another via a pivot axle (9), an adjusting device (10) is mounted on at least one of these bearing parts. For this purpose, at least this one bearing part has two elements (12, 18) which are coupled to one another via the adjusting device (10). Advantageously, the two elements (12, 18) of the bearing part (7, 8) are coupled to one another via a displacement device with a displacement eccentric (15). A horizontal guide (16, 17; 21, 22) and a vertical longitudinal slot (19) for the eccentric (15) guarantee a clean lateral displacement during the rotation of the eccentric. <IMAGE>

Description

The invention relates to a side-adjustable pivot bearing which can be fastened to a wing of a door or a window and has an axis of rotation, in particular for connecting two wings of a sliding folding door or a sliding folding window, with a first bearing part which can be attached to the first leaf and a second bearing part which can be fastened to the second leaf, at least one of the bearing parts has at least two elements which are coupled to one another via an adjusting device having an adjusting eccentric for at least one adjustment movement directed approximately parallel to the sash plane, the adjusting eccentric also engaging in a vertical longitudinal slot forming a first receptacle, the width of which corresponds approximately to the diameter of the eccentric and which is located on a second element of the first bearing part, while the first element of the latter is held on the wing and carries the adjusting eccentric and wherein the second element receives the axis of rotation. In the preferred field of application of such a pivot bearing, adjacent wings are generally connected to two pivot bearings of this type arranged one above the other. With heavy wings, there can be more. In the case of a sliding folding door, the pivot bearing is or are mounted alternately on the inside and outside of two adjacent sashes, so that the sashes can be folded into a package and pushed to the side.

If, in such an application, the inevitable manufacturing tolerances of the sashes, which are manufactured per se with the same machine setting, add up unfortunate and if they have an effect at one end, for example on the closing side, the entire sliding folding window or the entire sliding folding door may not function properly. For this reason, the total tolerance must be distributed as evenly as possible over the whole unit. Then the partial tolerances, for example for the overall width, do not have an overall disadvantage, and this applies, for example, with regard to the required tightness.

EP-A-0259618 discloses a door and window hinge that is adjustable during and after assembly. For the adjustment device, apart from the eccentric, a base plate and a cover plate are required, between which the tab of the one band body, which is provided with an elongated hole, is arranged. The eccentric bolt is mounted in both plates and its rotation causes the door or window to be adjusted laterally. The known adjustment device has the disadvantage that it is a relatively complex construction with a relatively large number of individual parts.

It is the object of the invention to design a generic pivot bearing in such a way that a particularly simple, and therefore inexpensive and easy to assemble construction results and nevertheless simple, quick and precise alignment of one door with respect to the other is possible. In the case of a sliding folding door, you can e.g. Bring all neighboring wings to the same side distance and thereby ensure a good seal between two adjacent wings.

This object is achieved in a rotary bearing of the type described in the preamble of claim 1 by the training according to the characterizing part of this claim. This means that only very few individual parts are required, and you get a compact bearing that can be delivered pre-assembled without loose parts. As a rule, it is sufficient if one of the two bearing parts, which are connected to one another via the axis of rotation, is equipped with an adjusting device which allows its wing to be adjusted relative to the neighboring wing within the common wing plane. In normal cases, it is sufficient to set the side spacing of adjacent wings to the desired level using the adjustment device. Due to the rotary bearings, adjustment in the vertical direction is usually not necessary. If a correction is necessary, this is done e.g. about the drives. As a result, the adjusting device is designed such that it enables at least one lateral adjustment of one wing relative to the other.

Characterized in that the adjustment movement is effected by the known use of an eccentric rotation, that the eccentric is attached to a first element of the bearing part rotatably connected to the wing and that it engages in a first receptacle of the second element receiving the axis of rotation, the first The slot is shaped like a slot and the slot width corresponds approximately to the diameter of the eccentric, the first element can be rotated on the wing but cannot be moved in the direction of its axis of rotation or transversely to it and the associated eccentric engages in a slot-shaped slot whose width corresponds to the diameter of the eccentric if it is a pin arranged eccentrically to the axis of rotation ―, rotation of the first element about its geometric axis via the eccentric and the receptacle adjust the second element relative to the first within a plane parallel to the wings. The above applies analogously to a cam-like eccentric.

The slit-shaped first receptacle extends in the vertical direction, and the second element is provided with at least one horizontally extending opening for a fastening element, in particular a fastening screw and / or a horizontally extending second slit-like receptacle for a sliding block-like attachment of the first element. The slot height of the second receptacle corresponds approximately to the height or the diameter of the attachment. The one arranged laterally to the axis of rotation of the first element Existing eccentric pins can move up and down in this vertical slot-shaped receptacle when the first element rotates, so that only its horizontally directed component is used for the adjustment. In order to enable this horizontal movement in the case of a fastening screw that has already been screwed in and to have a sufficiently large tolerance available with regard to its fastening, this fastening element penetrates a horizontally extending breakthrough of the second element. At least two fastening elements are expediently provided, and thus two, in particular superimposed, horizontal openings for the fastening screws on the second element. In addition, but in particular instead, the horizontal guidance takes place through the second slot-like receptacle and the stationary, sliding-stone-like attachment of the first element engaging therein

A further development of the invention provides that the eccentric passes through the first slot-shaped receptacle and its projecting end is deformed into a rivet head. This has particular advantages in terms of production technology. In a further embodiment of the invention, an insertion receptacle for a turning tool is attached to the rivet head, for example a hexagon socket, cross recess, slot or the like. This is easily accessible and thus the setting can be made easily.

A preferred embodiment of the invention is characterized in that a disc spring and / or an annular disc is inserted between the rivet head and the second element of the bearing part, which ensures good rotation of the eccentric in its vertical slot, but on the other hand prevents a relative movement perpendicular to the wing plane. Another variant of the invention results from claim 4. The disc-shaped intermediate piece or the approach of the first element is integrally formed on the latter and alone guarantees a perfect horizontal guidance in connection with the second slot-like receptacle.

The non-adjustable bearing part is expediently equipped with at least one drilling pin and the like. It is therefore easy and precise to attach and is secured by at least one screw or the like fastening element for securing purposes. The lateral distance of the one or more drilling pins of the one bearing part from the axis of rotation is greater than that of the bearing pin of the first element of the other bearing part from this axis of rotation. As a result, the second element provided with the bearing journal or journals is wider in the horizontal direction, measured transversely to the geometric axis of rotation, than the bearing part provided with the adjusting device. Thus, on the one hand, the adjusting device has a relatively small lateral distance from the axis of rotation, which is advantageous with regard to the forces, and, on the other hand, even with a wing provided with a flap, the tapping pin or pins can be pressed far enough into the material from the flap. This is desirable in terms of the stability and load of the wing spar provided with the flap. In addition, the axis of rotation can be partially provided with knurling so that it is secured against moving, in particular against falling out, without further measures.

Another embodiment of the invention is set out in claim 6. The caps mentioned therein are expediently made of plastic and clipped onto the bearing eyes. You can color-match them to the material of the wing. In contrast, it is advisable to manufacture the bearing parts from die-cast material, in particular as zinc die-cast parts.

Of two wings 1 and 2 connected to one another via at least one rotary bearing, only the mutually associated vertical bars 3 and 4 are shown in section in FIG. 1. If these sashes are the sashes of a sliding folding door, then this can comprise more than two sashes in a known manner, with adjacent sashes always being rotatably connected to one another via at least one, but preferably two or three pivot bearings arranged one above the other. The pivot bearings are alternately on the inside 5 and the outside 6 of the sliding folding door or the like.

The pivot bearing consists of a first bearing part 7 attached to the first wing 1 and a second bearing part 8 fastened to the second wing 2. Both are coupled to one another via an axis of rotation 9. At least one of these bearing parts, in particular the first bearing part 7, consists essentially of two elements which can be adjusted relative to one another by means of an adjusting device 10. The adjusting device 10 enables a relative movement of the two wings 1 and 2. This allows, for example, their lateral spacing 11 to be changed. The adjustment takes place in or parallel to the common wing plane of the closed one Door. The first element 12 of the first bearing part 7 consists of a bearing journal 13 which is rotatably mounted in a bore 14 of the vertical beam 3 and an eccentric 15. Between the two is an extension 16 consisting of a disc-shaped intermediate piece, which in a rear slot-like second receptacle 17 of the second element 18 of the first bearing part is housed. The geometric axis of this intermediate piece is identical to that of the journal 13. The eccentric 15 also consists of a pin whose geometric axis according to FIG. 1 is laterally offset from that of the bearing pin 13.

The adjusting eccentric 15 engages in a first receptacle 19 of the second element 18, its free end projecting outwards. It is deformed into a rivet head 20. The first receptacle 19 is a longitudinal slot extending perpendicular to the image plane and thus parallel to the axis of rotation 9. Its width corresponds to the diameter of the pin-shaped eccentric 15, and the length is determined by the movement of the eccentric and the geometric axis of the bearing pin 13.

In particular, due to the horizontal guidance through the horizontal second slot-like receptacle of the second element and the sliding block-like extension of the first element of the bearing part engaging therein, the second element 18 can only be displaced in the horizontal direction with respect to the first element 12. As a result, the first wing can only be aligned with the second or vice versa in the horizontal direction. Vertical alignment is deliberately switched off.

The first element 12 is held immovably in the vertical slot-shaped first receptacle 19 of the second element 18 by riveting transversely to the wing plane. In the exemplary embodiment, a plate spring 23 is connected between the second element 18 and the rivet head 20. Instead or in addition, a washer can also be used.

The second bearing part 8, which is not equipped with an adjusting device in the exemplary embodiment, is equipped with at least one, but in the exemplary embodiment with two spaced-apart boring pins 24 and 25. Each is pressed into a corresponding bore 26 in the associated wing or wing spar 4. Otherwise, the second bearing part 8 consists essentially of a plate-shaped base body and a centrally arranged bearing eye 27. It is located between two bearing eyes 28 and 29 of the first bearing part 7. In addition, four mounting holes 30 are made on the second bearing part 8.

From Fig. 1 it can be seen that, measured in the horizontal direction, the second bearing part 8 is significantly wider than the first bearing part 7. This allows the bores 26 for the drilling pins 24, 25 to be made far enough from a rollover 30 of the second wing 2 . On the other hand, however, the lateral distance of the journal 13 from the axis of rotation 9 is substantially smaller than the lateral distance of the axis of rotation 9 from a plane defined by the drilling pins 24 and 25, and this has a very positive effect with regard to the forces acting on it. After the assembly of the two bearing parts 7 and 8 and the attachment of all fastening screws, a cover cap 31 or 32 can be placed on each of the two bearing parts 7 and 8, in particular blown onto the bearing eyes. This is possible due to the plastic production and the attachment or the presence of appropriate slots.

If the wings to be connected to one another are correctly aligned, then they are connected via at least one, but preferably two or three pivot bearings of this type arranged one above the other. The bearings are initially fully assembled without the caps 31 and 32. Subsequently, the fastening screws penetrating the openings 21 and 22 are loosened slightly and the fine adjustment of one wing relative to its neighboring wing is now carried out with the aid of the adjusting device 10. Then the loosened screws are tightened again and the cover caps are opened.
