Description

The invention relates to a fitting for sliding doors, those in the closed state side by side are arranged and at least one of which Transfer of one of the doors from the closed to the opened state by the sliding movement automatically in a plane parallel to that of the rest Doors and in the closed state in the common level of the other doors is movable with two parallel to each other in the direction of displacement running fixed top rails, with the sliding doors remaining on one level above first upper bearing on the front and that from the plane of the first sliding doors move out second sliding door the rear track can be moved via a sliding upper bearing and with adjustable supports with a pair of parallel to each other and to the upper rails running lower guide rails for mounting and Guide the lower end of the door, being the Sliding top bearing one of the rear track assigned, only movable along the running rail Roller table and one across the top of the second sliding door attached sliding bracket and between the two towards the level of the first doors effective return spring is arranged.  

Based on this, it is known that not additional Doors with support rollers that can be moved transversely to the sliding direction to be provided, which run against an adjustment rail. This is via an angle lever gear with the roller table connected on the one hand and the sliding table on the other. This creates a displacement force on the displacement halter exercised and this and with it the associated door adjusted (EP 01 95 880 A2).

The fitting extends across the entire door width, because the adjustment rail must also over the Extend door width when holding in all positions the door that can also be moved transversely in the other Doors parallel shifted level should be guaranteed. However, a position is reached where a first door fully covered by the second sliding door will no longer be guided by the support rollers taken over and it can happen that the adjustment rail bears against the inside of the second door, resulting in a Increase the displacement and damage to the Surface of the sliding door can lead.

After all, due to the training is an easy one Adaptation to different door widths is not possible, it is a separate fitting is required. About that is also due to the indirect activity over the Lever drive a considerable effort to operate. The Angle lever drive generated due to its arrangement in the Moment when one of the doors moved to open the smallest adjustment force for transverse displacement. In this moment, however, becomes an easy adjustment the greatest possible force is required. Therefore, it is only possible the door closed in just one of the two shooting directions move to reach an opening.

Based on this, the present invention is the Task to create a fitting that with simple means an additional cross adjustment of the doors, triggered by a sliding movement of a Door in any sliding direction with little force wall and safe holding in the shifted plane allowed.

This object is achieved in that the second, additionally movable transversely to the direction of displacement Door on its two side edges in the area of the Adjustment sub and / or upper shift bearings arranged Support bearings and the other doors on the support bearings Supporting control surfaces during displacement containing control bars are assigned, which are related to the running rail and the guide rail starting from the with both side edges of the associated door increasing and then constant distance to the associated running or guide rail.

Regardless of whether the one with an additional Transverse sliding device provided second door or the first doors are moved in the direction of displacement an adjustment of the additionally sliding door through the doors that can only be moved on one level Start by direct actuation. This means that the controls with the one level only sliding doors are connected directly to the Fitting the additionally sliding door interact and this is immediately moved into the Transfer level. There is also a simple one Structure, as necessary for indirect operation Lever can be omitted. The start of the control surfaces allows little effort. The structure allows the second door to be initially in the area of the Side edge of a control bar of a first door is applied, cross-adjusted and at progressive shift an adjustment in the parallel plane takes place.

The present invention relates to a sliding door system, which has two different types of sliding doors. These are first sliding doors 1 that can only be moved in one plane. Level 1 can be seen as the front surface of these sliding doors 1 from FIGS. 3 to 6. The sliding door system comprises a second door 2 , which in addition to the adjustment in the displacement direction can also be transferred transversely to a second plane E 2 , this plane E 2 running parallel to the plane E 1 , but relative to the upper rails 4 , 5 and lower guide rails 9 , 10 have a greater distance when positioned in plane E 2 than when positioned in plane E 1 . In position in the plane E 2, the second door 2 can be moved away or a door 1 can be moved behind the door 2 via one of the first doors. 1

Such a position of the first door 1 in relation to the door 2 can be seen from FIG. 1 and only for the region of the upper running rails 4 , 5 . The first doors 1 have in the region on their side edges 13, 14 the upper bearing 3, which each comprise a guide roller 53, with which they rest on the front upper rail 3 and are movable therealong.

In addition to the upper bearings 3 arranged in the area of the upper edges 11 of the first doors 1 , lower bearings 7 are assigned to the first doors. These sub-bearings 7 are also each arranged in the region of the side edges 13 , 14 of the first door 1 , but are assigned to the lower edges 12 . The sub-bearings 7 of the first door 1 comprise a bracket, one leg of which is connected to the rear of the first door 1 and the second leg of which comprises a guide roller which can be rotated about a vertical axis and which engages in the front lower guide rail g .

The two upper rails 4 , 5 and the two lower guide rails 9 , 10 each form a structural unit and are assigned to the body of the cabinet.

In the closed position, the first doors 1 and the second door 2 form a common plane, ie the front surface of the second door 2 also lies in the plane of the front surfaces E 1 of the first doors 1 . However, such a position does not allow the doors 1 or 2 to be moved in the direction of the opening. In order to be able to open one of the doors, at least one of the doors, in this case door 2 , must also perform a transverse movement in addition to a sliding movement. In the exemplary embodiment explained below, a door, namely the second door 2 , is cross-adjustable and for this purpose it has a sliding upper bearing 6 in the region of its upper edge 15 , namely on the side edges 17 , 18 and in each case in the region of its lower edge 16 the side edges 17 , 18 , an adjustable sub-bearing 8 .

The sliding upper bearing 6 and the adjusting lower bearing 8 of the second door 2 work together with control strips 39 which are assigned to the first doors 1 in the area of their upper edges 11 and lower edges 12 , respectively. These control strips 39 are provided with control surfaces 24 , 25 , which cooperate with support rollers 22 , 23 of the sliding upper bearing 6 or adjusting lower bearing 8 . The control surfaces 24 , 25 have a course which, starting from the smallest possible distance to the assigned running rail 4 with respect to the upper bearing 3 or to the front lower guide rail 9 with respect to the lower bearing 7 and starting therefrom, runs at an increasing distance, and then into a surface to pass, which is arranged parallel to the rails 4 , 5 and the guide rails 9 , 10 running at a constant distance. These control strips 39 can also be a direct component of the upper edge or lower edge of the first door.

The structure and the mode of operation of the sliding upper bearing 6 of the second door are first described below.

As can be seen from Fig. 1, the sliding upper bearing 6 comprises a sliding holder 20 which is formed as an angle, which has a first leg which is assigned to the area of the upper edge 15 and one of the side edge 17 , 18 of the second door. The leg is attached to the door 2 by screws, not shown.

With its horizontally extending leg, the sliding holder 20 rests on a roller table 19 . The roller table 19 comprises the bearing roller 51 with which it can be moved along the rear running rail 5 . The bearing roller 51 is attached to a bearing bracket which is connected to the plate of the roller table. In the roller table 19 there are impressions which form bearing seats for support rollers 37 . The support rollers 37 have axes of rotation 38 which are accommodated in the pockets of the roller table. The axes of rotation 38 run parallel to the longitudinal extent of the running rail 5 . The horizontally extending portion of the transfer holder 20 lies with its underside on the support rollers 37 and is thus transversely to the displacement or rollingly moved to the movement direction of the bearing rollers 51st The sliding holder 20 has two guide slots 34 , 35 which run parallel to one another but extend transversely to the course of the running rails 5 . In the slot 35 , a bearing bush 6 or roller is inserted, which is penetrated by a fastening pin 33 with a collar. This fastening pin 33 can be designed, for example, in the form of a screw which can be screwed into a bore of the roller table 19 with its other end, which is offset, or riveted to it. The guide slot 34 is parallel offset in the direction of movement of the roller table in the horizontally extending surface of the sliding holder 20 and is also additionally offset in the direction of the extension of the guide slot. A bearing bush 36 is also inserted into the guide slot 34 , and a bearing pin 27 designed as a screw pin is also provided, which has a collar surface on which a control lever 29 with a bore is mounted. The bearing pin 27 passes through the bore in the control lever 29 , the bearing bush 36 and thus the displacement holder 20 and is screwed into a threaded bore in the roller table 19 . Due to the connection by the journals 33 and 27 , the displacement holder 20 is held on the roller table 19 so as to be displaceable only in the transverse direction to the direction of movement of the roller table 19 . Because of the support rollers 37 provided , namely three such rollers 37 , the displacement holder 20 can be easily moved relative to the roller table 19 .

Finally, a further control lever 30 is articulated on the displacement holder 20 . For this purpose, it is attached via a first bearing pin 26 , which extends through a bore in the displacement holder 20 and a bore at one end of the control lever so as to be pivotable about a vertical axis. The other end of the control lever has a hinge pin 32 which extends through a bore at the end of the control lever 29 and also through a bore in a coupling rod 31 . Together, these form the articulation point 28 . The hinge pin 32 is provided with a thread so that the components, ie the control levers 29 and 30 and the coupling rod 31 are held together in the region of the hinge point.

The mounting bracket assigned to the bearing roller 51 is firmly connected to the roller table 19 by means of pin attachments which engage in corresponding bores, for example by caulking the attachments.

In addition, the roller table 19 has a further bearing bracket 49 , to which a return spring 21 is suspended at one end via a bore. The other end of the return spring 21 receives an insert which has a threaded bore into which an adjusting screw supported on a bearing block 50 can be screwed. The return spring 21 causes the slide holder 20 and the roller table 19 to be held in the retracted position, ie that the second door 2 is always kept acted on in the direction of the running rails 4, 5 in order to be returned to the plane E 1 .

As can be seen from FIGS. 3 and 4, two upper shift bearings 6 or the articulation points 28 of the control levers 29 , 30 assigned to them are connected to one another via the coupling rod 31 . The coupling rod 31 effects a coupling of the movement of the two upper sliding bearings 6 in the sense of a parallel adjustment, so that when the second door 2 is to be moved from a side edge 17 or 18 into the plane E 2 , namely by the support rollers 22 , 23 on the associated control surfaces 24 and 25 , the second adjustment upper bearing 6 is also moved parallel to this also via the lever mechanism consisting of the coupling rod 31 and the two control levers 29 , 30 . For different door widths, it is possible to make an adjustment in that the perforations provided in the coupling rod 31 are assigned in accordance with the hinge pin 32 . However, the upper shift bearing 6 is also functional if no control lever 29 , 30 and no coupling rod 31 is provided, but if there is a connection only via the journal 27 and a connection of the shift holder 20 to the roller table 19 .

The movement orientation or adjustment from plane E 1 to plane E 2 with respect to the second sliding door 2 then takes place only by the support rollers 22 , 33 bearing on the control strips 39 . In the completely open position, ie when the second door 2 is located with its front surface in the plane E 2 , the support roller 23 is supported on the control surface of the control strip 39 which runs parallel to the front surface. When one of the doors, namely a first door 1 or the second door 2, is displaced, the control surface 24 or 25 first comes into contact with the roller 22 and then with the roller 23 . As a result, the second door 2 is moved directly in the direction of the plane E 2 . The transverse movement comes to an end when the second support roller 23 rests on the control surface of the control bar 39 which runs parallel to the running rail 5 . The second door 2 can be reset to the level E 1 when there is no longer any contact with the control surfaces 24 , 25 . The reset takes place via the return springs 21 . The preload of the return springs 21 can be adjusted via the set screw assigned to them, and depending on the weight of the door, the required return force can be adjusted.

However, it is necessary that the upper edge 15 of the first door and the lower edge 16 of the second door 2 execute a movement parallel to one another when displaced. For this reason, the second door 2 is provided with an adjustment sub- bearing 8 , which is described in more detail with reference to FIGS. 2 and 5 and 6. The Verstellunter camp 8 also includes a bracket 40 with a vertical leg, which is arranged in the region of the lower edge 16 of the second door and in each case in the region of the side edges 17 , 18 .

There are therefore also two adjustment sub-bearings 8 , which are each assigned to the side edges 17 and 18 , respectively. The vertical legs are screwed to the back of the second door 2 . The bracket 14 includes a horizontally extending leg, on which two support rollers 22 , 23 are also arranged, which cooperate with control strips 39 , which are assigned to the first doors 1 and their lower edges 12 . The control strips 39 which are assigned to the lower edges 12 of the first doors 1 correspond to those which are associated with the upper edges 11 thereof. They also ensure in the case of contact with the support rollers 22 , 23 with their control surfaces 24 and 25, respectively, for an adjustment of the lower edge 16 of the second door 2 into a shifted plane E 2 . The adjustment sub-bearing 8 further comprises an articulated lever 48 , which is articulated at one end at an articulation point 47 to the horizontally extending part of the bracket 40 . The articulated lever 41 is pivotable about a vertical axis. The horizontal leg of the bracket 40 has an arc slot 44 . The arch slot 44 is penetrated by a stop pin 45 which is connected to the articulated lever 41 . The articulated lever 41 is limited in its pivoting movement via the stop pin 45 and the arch slot 44 . On the stop pin 45 engages a tension spring 48 which is supported at its other end with the interposition of a screw on a support bearing. The bias of the tension spring 48 is adjustable. The free end of the articulated lever 41 is provided with a journal bearing 52 , to which a guide roller 42 is assigned. An articulated rod 43 with a bore can be attached to the journal bearing 52 , which is used to connect the articulated lever 41 , the adjustment support 8 , which is assigned to one side edge 18 of the second door, with the articulated lever 41 of the adjustment support 8 , which is assigned to the second side edge 17 , serves. As a result, the movement is coupled in the sense of a parallelogram transmission.

The guide roller 41 engages in the lower rear guide rail 10 . Since the second door 2 is arranged on the rear upper running rail 5 and is mounted eccentrically, the weight of the door 2 tilts around the rear upper running rail 5 .

Due to the tension spring 48 in connection with the articulated lever 41 , a force can be exerted on the lower edge 16 of the second door 2 , which causes the front surface of the second door 2 to be held in parallel, the preload of the tension spring being adjusted by the adjusting screw in accordance with the weight. So that a dead center position is avoided, it is provided that an end position of the articulated lever 41 in the arch slot 44 is arranged such that an angle is included which is smaller with respect to a plane parallel to the guide rail through the articulation point 27 with the axis 46 of the articulated lever 41 than the right angle or deviates from the right angle. In contrast to the sliding upper bearing 6 , the tension spring 48 of the adjustable lower bearing 9 does not ensure a return to the plane E 1, but only serves to balance the moment that occurs due to the eccentric support in the area of the sliding upper bearing 6 .
