Description

The invention relates to a fitting for the closed state in a plane next to each other arranged doors of a sliding door system, with first doors, that always remain in one level and over their top and lower edges assigned upper and lower bearings along front upper and lower rails are slidable, and with at least one second door, each one above the other spaced, associated with their upper door edge Sliding upper bearing and the lower door edge assigned Adjustable sub-bearing along to the rails of the first doors parallel rails and is movable transversely to the course of the rails, the Shift upper bearing from one only along the rear Slidable roller table, a transversely movable rail Slide holder and from a slide holder in Direction of the closed state Return spring consist of and being a kind of door Support bearings are assigned, to which there is a shift a control bar assigned to the other type of door supported with control surfaces.

In such a solution known from EP 01 95 880 A2 are the doors that can only be moved on one level provided with support rollers against an adjustment rail start, which is assigned to the door, which can also be moved transversely  is. This is via an angle lever gear with the roller table on the one hand and the sliding table on the other connected. As a result, a displacement force on the Sliding bracket exercised and this adjusts the associated Door.

The fitting requires an adjustment rail that extends over the entire door width extends when in all sliding positions holding the sliding door in the level shifted parallel to the first doors should be. However, if a position is reached at the first door full of the second one that can be moved laterally Door is covered, no more guidance from the Support rollers taken over so that the adjustment rail on the inside of the second door. this leads to an increase in displacement and possibly to Damage to the surface of the sliding door.

It is also easy to adapt to different door widths not possible. It is a separate one Fitting required. From indirect actuation via the bell crank drive follows that when one of the doors only the smallest adjustment force is moved for the purpose of opening is generated for transverse displacement. At this moment However, for easy adjustment, it is as large as possible Strength needed. Therefore, it is only possible in only one of the Both sliding directions move the door to an opening to reach.

A sliding door arrangement is known from EP 00 75 364 A2, at the two separate sliding bearings the side edges are assigned to the transversely adjustable door. Their movement in the parallel shifted plane, however, takes place independently from each other.  

The invention has for its object a fitting to create an additional one with simple means Cross adjustment of one of the doors, triggered by one Movement of a door in any direction with little effort and secure hold in the shifted Level allowed.

This object is achieved with the features of the license plate of claim 1 solved.

This is a lighter compared to the known solutions Cross adjustment possible because of direct actuation the door enters. Furthermore, regardless of whether the second door or the first doors in the direction of displacement be moved, an adjustment of the sliding door when starting by direct actuation. The controls the one with the doors remaining on one level connected, act directly with the fitting of the cross-movable Door together and adjust it immediately. The result is a simple structure and a smaller one Effort.

There is only one for adapting to different door widths changed coupling rod length required. The Coupling rod e.g. already be provided with grid perforations, that allow customization.

To achieve a safe parallel guidance of the sliding holder with respect to the roller table, it is provided that two pins are assigned to the roller table, which are arranged with respect to the associated running rail along the same at a distance from one another and transversely therewith at different distances from the running rail and parallel to one another, but transverse to Grip through the running guide slots in the sliding bracket.

Finally, it is provided in a further embodiment that one of the pins also assigned to the roller table Bearing journal forms.

To reduce friction, the pins are with bearing bushes or provided rollers in the guide slots are led.

Furthermore, to reduce the friction between the Roller table and the sliding holder in a further embodiment provided that the roller table with several support rollers with parallel to the guide rail Axis of rotation is provided on which the sliding holder lies on. It is provided that at least one of the Pin to secure the sliding holder against the Roller table is formed.

Finally, another feature of the invention to reduce the adjustment movement of the second Door required displacement force provided that Design support bearings as roles. The support bearings are preferably assigned to the slide holder.

The control bars are the top edge of the first door assigned and either as separate components or as Train part of the first doors.

According to a further embodiment of the invention, that the bottom edge of the second door two in the area assigned to their side edges arranged adjustable sub-bearings are each one bracket, one each on the bracket articulated around a vertical axis limited pivoting lever and at its free  End rotatably attached and in the rear lower Guide rail engaging guide roller, wherein the free end of the articulated lever of the two adjustable sub-bearings are coupled together via an articulated rod.

This training ensures that a secure parallel displacement of the lower edges of the cross sliding door in the parallel plane.

Finally, the invention is in a further embodiment provided that between the bracket and the articulated lever a tension spring is arranged on the lower edge the second door is facing away from the guide rail Exerts force. Because the sliding door in its upper sliding bearing eccentric in relation to the upper rear track is arranged and in this respect the weight of the door leaf cause a tilting around the upper rear running rail this could result in an inclination of the Surrender door. This skewing can be done by a Setting the spring force of the tension spring in the range of Adjustment base can be compensated. About the mainspring a force is exerted on the articulated lever which Distance between the lower edge of the second door and the applied to the lower guide rail in the sense of an enlargement. This is an exact setting and balancing the weight of the second door in individual Possible depending on the material used.

Finally, the brackets are designed as rollers Support bearing assigned. These work with the bottom edges of the control surfaces associated with the first doors together.

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 direction of displacement, can also be transferred transversely thereto into a second plane E 2 , this plane E 2 running parallel to plane E 1 , but with respect to the upper rails 4 , 5 and the lower rails Guide rails 9 , 10 run in the position in E 1 , but are at a greater distance from the upper guide rails 4 , 5 or the lower guide rails 9 , 10 when they are in the plane E 2 than when they are in the 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 upper bearings 3 in the region of their side edges 13 , 14 , each of which comprises a guide roller 53 with which they rest on the front upper running rail 4 and can be moved along this.

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 9 .

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 support 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 designed as an angle, which has a first leg which is assigned to the region of the upper edge 15 and one on 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 horizontal surface of the slide holder 20 and also additionally offset in the direction of the extension of the guide slot. A bearing bush 36 is likewise inserted into the guide slot 34 , and a bearing journal 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 moved easily 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 approaches.

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 sliding 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 one of the first doors 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 resetting takes place via the resetting 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.

It is expedient 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 .

It is therefore also possible to provide 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 horizontal 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 their upper edges 11 . 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 . The stop pin 45 is engaged by 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 .
