description

The invention relates to a folding door with at least two door leaves, wherein the door wings are pivotally connected to each other and each rotatable and / or pivotally mounted about a vertical axis, according to the preamble of claim 1.

Folding doors are known as such in principle from practice. Folding doors are used in particular when the component opening, which is to be covered or closed by the folding doors, has only small dimensions (width) and, for example, for the use of sliding doors arranged in the component opening are unsuitable.

Object of the present invention is to further develop folding doors, in particular with regard to a simple mountability.

A folding door according to the invention has the features of claim 1. It is therefore provided that at least one bearing part for receiving a bearing means of a

Door leaf is formed in several parts, such that the bearing means in the partially disassembled bearing part can be inserted and that by mounting the bearing part the

Bearing means rotatably mounted on the bearing part. In other words, it is proposed to form the bearing part separable, so that the bearing means in particular without tilting the vertical (bearing) axis of the door leaf is inserted into the disassembled bearing part. By

Assembly of the bearing part is then a solid bearing for the bearing means of the

Door leaf created.

The advantages of this solution are obvious. Since the installation of folding doors in the area of a component opening usually has to take place under limited space, it is difficult in known solutions, the bearing means of the door, for example

Bearing journals that protrude upwards and downwards over the door leaf into corresponding ones Bearing parts, such as bushings above and below the door, introduce. Here, the invention provides a remedy by an at least two-piece and correspondingly dismantling bearing part is proposed. To assemble the door leaves, the bearing part is dismantled, so that the bearing means can be easily brought into position. Thereafter, the bearing part is reassembled and fixed the vertical axis of rotation of the door leaf.

The invention is preferably used in folding doors, in which the door leaves are mounted on the upper side and underside by means of at least one bearing means. It can be provided that a first door is mounted on the lower side fixed to a support member mounted on a base and that the stationary mounted on the ground first door leaf is preferably mounted in an upright axis fixed to a running rail arranged above the door rail. In such a mounting situation, an at least two-part bearing part is arranged in the running rail for stationary mounting of the door leaf, wherein on the door a bearing means is arranged, which projects upwards into the bearing rail and which is rotatably mounted in a bearing formed in the bearing bore or bearing bush. A special feature is preferably that the bore is formed by the two parts of the bearing part, such that by dismantling a part of the bearing part of the bearing pin of the door leaf is movable in the region of the bearing bush and that the bearing bush is closed by mounting the part.

Further details of the type of folding door result from the dependent claims.

Another special feature, which may also be an independent solution to the above-mentioned object, results from claim 9. Accordingly, the two door leaves are connected to each other in an edge region facing each other by hinges, wherein the hinges each have stop means for limiting the swing angle between the door leaves in one direction to a maximum of about 180 °.

Furthermore, protection is claimed for a fitting with an inventively designed bearing part. Further preferred embodiments and further developments of the invention will become apparent from the accompanying drawings and the description by the way.

A preferred embodiment of the invention will be explained below with reference to the drawing. In this show:

Fig. 1 to 3 show a folding door 10 which is positioned in a component opening 1 1. The component opening 1 1 is bounded laterally and above and below by walls of a component. In the present case, it should be assumed that the component opening 11 is delimited above by a lintel or a ceiling 12, laterally through soffits 13, for example, a wall and below through a bottom 14th In the exemplary embodiment shown, the folding door itself has two door wings 15, 16, which are mounted so as to be pivotable about a substantially vertical axis in the region of upright edges facing each other. For this purpose, use special hinges 17, which will be discussed below.

As can be seen from FIG. 2, one of the two door leaves 15 is fixedly mounted in a lateral edge region, whereas the other door leaf 16 is mounted displaceably in total. For this purpose, the other or second door leaf 16 is mounted on a carriage 18 which is movable in a running above the door leaf 15, 16 running rail 19. The running rail 19 is mounted in the usual way on the ceiling 12 and extends centrally along a longitudinal axis of the folding door 10. The carriage 18 is mounted as usual in the art on rollers 20 which are movable in the interior of the running rail 19 on legs 21 thereof. Between the legs 21 of the slides 19 enters a connecting means 46 for coupling the carriage 18 with the second door 16 through (see detail Z in Fig. 5).

The two door leaves 15, 16 are each rotatable or pivotable about a substantially vertical axis, namely the first door leaf 15 in stationary bearing points and the second door leaf 16 on the carriage 18.

The door wings 15, 16 have a peripheral outer frame, which is provided with a filling 22 and is closed by a filling 22. The frame consists of vertical frame profiles 23 and horizontal frame profiles 24, which are connected together in corner areas.

The stationary rotatable door leaf 15 is mounted in a fixed to the bottom 14 pivot bearing 25 as a bearing part 28. For this purpose, a bearing means 26 is arranged in the region of an underside of the door leaf 15. The bearing means 26 and the pivot bearing 25 are shown in Fig. 9. In the present case, the rotary bearing 25 is an elongated rail which has a series of recesses or openings 35. Other breakthroughs 35 serve to support the door leaf 15. From FIG. 9 it can be seen that an opening 35 for mounting the door leaf 15 is circular in shape for receiving The bearing pin 27 in turn is part of the substantially angularly formed bearing means 26. The bearing means 26 has two legs 29, 30, wherein the horizontally oriented leg 29 has the bearing pin 27 on the underside and the vertically aligned Leg 30 has a recess 31 for mounting the bearing means 26 on the frame of the door leaf 15 according to detail D in Fig. 4. In the present case, a mounting screw 32 engages through the recess 31 for attachment of the bearing means 26 on the frame. On the bearing pin 27, a sleeve 33 is further attached.

On the upper side, the door leaf 15 is also rotatably mounted stationary, namely with a bearing means 34 which is formed as the bearing means 26, but is mounted on the frame of the door leaf 15, that the bearing pin 27 facing upward. As a counterpart to the bearing member 28 is a specially adapted bearing member 36 is used. The bearing part 36 has a running rail 19 corresponding cross-sectional shape, so that the bearing part 36 can be positively held in the running rail 19 (see detail C in Fig. 5). For bearing or receiving the bearing pin 27, the bearing part 36 has a bore 37 in which the bearing pin 27 is rotatably receiving.

A special feature of the bearing part 36 is that it is formed in two parts. More specifically, the bearing part 36 is formed in two parts such that the area of the bore 37 is formed by two different parts of the bearing part 36. In this way, by dismantling the bearing part 36 of the bearing pin 27 can be inserted laterally into the bore 37 without the door 15 must be tilted for this purpose. In the present case, the bearing part 36 consists of a bearing part base 38 and a bearing part attachment 39 (FIG. 8), which, when combined, find a form-fitting fit in the running rail 19 (detail C in FIG. 5). The bearing part base 38 has a recess 40 into which the bearing part attachment 39 can be inserted. In the region of mutually facing boundary surfaces of the bearing part base 38 and the bearing part attachment 39, one half of the bore 37 is formed in each case, so that after mounting the bearing part attachment 39 on the bearing part base 38 a positive receptacle for the bearing pin 27 is formed. The mounting of the bearing part 36 in the running rail 19 is effected by a threaded bolt 41 which is rotatable in a threaded bore 54 in the bearing part base 38 against the upper wall of the running rail 19. The bearing part attachment 39 is fixed to the bearing part base 39 by means of a screw 42 (see detail B in Fig. 4).

The second door leaf 16 is coupled to the carriage 18 as already described. For this purpose, a substantially angular bearing means 43 is attached to the upper side of the frame of the door leaf 16. The bearing means 43, like the bearing means 34, has a horizontal leg 29 and a vertical leg 30. The vertical leg 30 is screwed to the door leaf 16 in the corner region of the frame. For this purpose, a bore 44 is provided in the vertical leg 30, through which a screw connection to the frame takes place (see detail A in FIG. 4). On the upper side, a laterally open receptacle 45 for a connection means 46 with the carriage 18 is provided on the horizontal leg 29. The connecting means 46 may also be a carrying bolt of the carriage 18. In any case, the connecting means 46 on the one hand with the carriage 18 can be coupled and on the other hand inserted into the laterally open receptacle 45 and fastened there. For this purpose, in the present case, the receptacle 45 opposite holes 47, through which the connecting means 46 can be fastened by a pin 48 in the receptacle 45. The pin 48 engages through a bore 49 in the connecting means 46 therethrough.

Another particularity relates to the hinges 17 for connecting the two door leaves 15, 16. In the present case, the door wings 15, 16 are interconnected by three identical hinges 17, which are arranged in the upper, in the lower and in the central region of the door wings 15, 16 , The hinges 17 are mounted on a flat rear side of the frame profiles 23. For this purpose, the hinges 17 on their hinge wings 50, 51 holes 52 through which an attachment to the frame profiles 23 takes place. The peculiarity of the hinges 17 is, on the one hand, that the maximum opening angle is limited to approximately 180 ° by stop means 53 integrally formed on the rear side of the hinge wings 50, 51. The stop means 53 are arranged so that they hit each other when the maximum opening angle is reached and limit further pivoting of the two door leaves 15, 16 relative to each other. In the present case, the stop means 53 strike against each other with the door leaves 15, 16 closed. On the other hand, a special feature is that the Stop means 53 have only a small thickness or material thickness, namely such that both stop means 53 can enter together in an air gap between the two closed doors 15, 16. In this way, the stop means 53 when closing the doors 15, 16 is not a hindrance.
