Description

The invention relates to a sliding door fitting for a furniture according to the preamble of claim 1 and a piece of furniture with such a fitting.

Sliding door hardware and furniture with such fittings are known from the prior art for a long time. Recent versions of such fittings and furniture reveal the EP 1 613 831 A1 , the EP 2 412 906 A1 , the WO 2010/095029 A3 and the WO 2011 / 079400A1 , The background to this development is that more and more flush-fitting sliding door systems in the field of office furniture, living and sleeping furniture and in the kitchen and bathroom are used or desired in lower cabinets, wall cabinets and sideboards for high-quality furniture segments. The term "cabinet" is to be understood in the following as well as if necessary in the claims not restrictive but is used synonymously for furniture with a body with sliding door (s).

The well-known sliding door fittings and the furniture provided with such furniture have in common that they do not ensure simple design of length and / or installation width of the furniture, that they do not provide versatility from a hanging to a standing furniture system and that a change in the handle opening position, if any, only possible with restrictions.

The invention sets in the task of solving these problems.

The invention solves this object with respect to the sliding door fitting by the subject-matter of claim 1 and with respect to the sliding door furniture by the subject-matter of claim 17.

Advantageous embodiments can be found in the dependent claims.

According to the characterizing part of claim 1, a control roller is arranged to control the sliding joint movement of the thrust means of the first and second outer and inner guide carriage only on one of the inner guide carriage of each carriage assembly, which is guided in a corresponding control contour of the rail device. The subject of claim 1 is particularly advantageous that by the toggle kinematics (arrangement), which is controlled by a single control role on the respective carriage assemblies, no second curve pieces and roller conveyors are needed. With the invention, therefore, a sliding door fitting for a flush sliding door furniture (for example, both sliding doors are in the closed state in a plane) created that eliminates part of the above-mentioned disadvantages of the sliding door fittings from the prior art.

The furniture consists of a furniture body, which is formed in a preferred embodiment, at least to a front side open and closed on the other sides such as top wall, bottom wall and rear wall. It is also conceivable, however, that at least one further side, for example the rear wall, is designed to be open.

At least one closure element, preferably a sliding door, is arranged in front of the at least one open side of the furniture body, which is arranged to be movable relative to the furniture body and to a further closure element which lies in the closed position in a common plane to the closure element. As a further closure element, a further sliding door can be used in a particularly advantageous manner, but also conceivable are hinged doors, drawer arrangements, flaps, shelving systems or the like.

The control roller is preferably arranged on the first inner guide carriage, but may also be arranged on the other inner guide carriage or on one of these inner carriage defined element.

During the opening of the respective sliding door, the manual force causes the sliding door to swing open, so that it is guided from its flush starting position into a parallel position at a defined distance from the body. Simultaneously with the pivoting movement, the sliding door is moved already defined laterally to the body.

In order to make a smooth transition, the panning and parallel processes were coupled together in a particularly simple manner. Thus, the problem of the sudden transition of both movements of panning was avoided in a method in the sliding direction. Due to the multi-joint lever kinematics used, the overall result is a harmonious sequence of movements. A vibration excitation of the sliding door is also avoided. The same advantages arise conversely when closing the sliding door

It is possible to open the sliding door from any grip position.

By choosing the appropriate installation width set, the customer can individually choose the installation width. Paving width means the distance from the inside of the sliding door in the closed state to the inside of the same sliding door in the open state. To this end the curved pieces are exchanged and the connecting lever undergoes a different positioning. For a simple installation width assembly of the furniture is guaranteed.

Length customization of the furniture is made possible by merely mechanically cutting the rail device and the control part in a simple manner and selecting the corresponding carriage arrangement which is adapted to the furniture carcass width.

For a simple length and / or Einbaubreitenkanfektionierung the furniture is guaranteed, so that body dimensions of various kinds can be easily implemented and customized adjustments are minimized.

A middle wall is not necessarily needed for the hardware construction, but if present, does not affect full access to the interior of the furniture.

A function of the fitting is given even with a 180 ° rotation of the overall fitting, which offers a simple convertibility of a hanging to a standing furniture system and vice versa.

There is no need to edit the sliding door edges. In addition, there is no minor closure edge, i. All points of the sliding door move away from the body during the opening movement.

The sliding door fitting according to the invention enables a "driving ahead" of the sliding doors, wherein preferably a full access to the storage space in the furniture is possible. For example, a folder assembly in full interior width and height is possible and it is also a use of example excerpts well feasible.

The fitting is also suitable for doors made of various materials such as wood, metal, glass or combinations thereof.

The invention also provides by the subject matter of claim 16, the advantageous use of a locking element. This use of a locking element serves only to prevent relative movements of fitting elements of a sliding door fitting, in particular of the two inner guide carriages to the two outer guide carriages of a slide arrangement of the sliding door fitting, via a defined partial path, preferably less than 50% of the total displacement path of a sliding door.

Terms used above, below, right, left, etc., refer only to the drawing and the preferred arrangement shown in these drawings, but are not to be construed to understand or to change the orientation of the installation position according to a coordinate system transformation in the changed orientation.

1 shows in a) to e) a sliding door furniture with a (furniture) body 1 , which in a preferred embodiment to a front side open and on the other sides (top wall 2 , Bottom wall 3 , right side wall 4 , left side wall 5 , Rear wall 6 ) is closed. Outside in front of the open front of the furniture body 1 are two sliding doors 7 . 8th relative to the body 1 and relative to each other with a sliding door fitting 9 movably arranged.

To realize the mobility of the sliding doors 7 . 8th serve two carriage arrangements 10 . 11 of the sliding door fitting 9 , The sliding doors 7 (right), 8th (left) are doing so with the help of the respective carriage arrangements 10 (right) and 11 (left) on the body 1 slidably guided that they can be pushed past each other over a part of their sliding path or their opening and closing path parallel to each other. It will be one of the number of sliding doors 7 . 8th corresponding number of carriage arrangements 10 . 11 used. Particularly advantageous is the fitting for two sliding doors 7 . 8th suitable, which lie in the closed position on the furniture body in a single common plane E1 (see 2a ).

To move from such a position one of the sliding doors - eg the sliding door 8th - to be able to open, this sliding door must 8th are first moved in a plane E1 spaced plane E2, in which they then on the other sliding door 7 can be moved over (and vice versa). This allows the sliding door fitting according to the invention 9 in an excellent way (see 2a ) to 2d )). The distance between E2 and E1 is also referred to below as the installation width B.

Each of the carriage arrangements 10 . 11 (see the 7a . 7b . 8th . 10a . 11a . 11b ) indicates to her the furniture (in the 1 the top wall 2 ) side facing a first outer (and the furniture body turned) carriage 12a and a second outer (and to the furniture carcass) carriage 12b on, spaced on the top wall 2 of the furniture (or alternatively below the bottom wall 3 of the body 1 , please refer 3a ) to 3e ) each by means of rollers or wheels on a rail device 13 ( 1 . 4 . 5 ) parallel to the open front side or parallel to the sliding direction X of the sliding door 7 . 8th is displaceable. The rail device 13 may be formed as a continuous casting profile (eg aluminum), but can also be made in other ways.

The rail device 13 has at least one on the top wall 2 (or below the bottom wall 3 , not shown here) fixed first roller conveyor 14 ( 11 ) for at least one or more first rollers 15 ( 7 . 11 ) and a second roller conveyor 16 ( 11 ) for at least one or more second rollers 17 ( 7 . 11 ) supported in parallel spaced planes. Here, in a preferred embodiment, four respective first and second rollers 15 . 17 ( 7 ) intended.

The roller conveyors 14 . 16 are preferably as in particular in cross-section U-shaped grooves in the rail device 13 designed ( 11c ). The grooves secure the rollers 15 . 17 against lifting and allow a smooth, safe moving the first and second outer carriage 12a , b in a main shift direction +/- X, the main sliding direction of the sliding doors 7 . 8th over the essential part (more than 50%) of the displacement path ( 1 ).

To the sliding doors 7 . 8th from the closed position on the furniture body 1 move out and around her at the other, in the closed position in the same plane E1 sliding door 7 . 8th It is possible to pass them by means of the carriage arrangements 10 . 11 of the sliding door fitting 9 move out of the plane E1 in the second plane E2, which is parallel to the plane E1, but so much farther from the furniture body is that the sliding doors 7 . 8th can be pushed past each other.

To achieve this, are on the first and second outer carriage 12a . 12b first and second inner carriages 18a . 18b arranged, relative to the outer carriage 12a . 12b can be moved to these in particular perpendicular to the planes E1, E2 ( 2 . 7 ).

Push devices S1 and S2 serve for this purpose between the first and second outer and inner guide carriages 12a . 18a respectively. 12b . 18b ( 8th ).

To form such thrust devices S1, S2 preferably as linear roller guides, the first and second inner guide carriage 18a . 18b again preferably several roles 19 . 20 on, in the corresponding roller conveyors 21 . 22 preferably in the manner of grooves in / on the first and second outer guide carriage 12a , b preferably perpendicular to the orientation of the rollers 15 . 17 or are also guided perpendicular to the planes E1, E2 ( 7 . 10b . 11c ). The roles 19 . 20 are as single rolls or as double rolls and the roller conveyors 21 . 22 preferably formed as individual grooves or pairs of grooves, which allows a particularly good and smooth running guide.

The first and second inner carriages 18a , b also each have at least one boom (web) 30 . 31 on, on which at fastening means (here at pin 23 ; please refer 8th and 9 ) the respective sliding door 7 . 8th is fastened or fastened, the suitable fittings for this purpose 24 can have ( 1 ).

The 11c and 11d show how the boom 30 arranged cones 23 in an opening on the fitting part 24 , which is on the sliding door 8th is fixed. This is the sliding door 8th adjustable in height and / or width in a manner known in the art. Furthermore, the sliding door can 8th but through the pin 23 be set by means of a thread over an adjustment Z in the adjustment Y variable in depth.

Every jib footbridge 30 . 31 may be formed in the manner of an angle piece, one end of the pin 23 or the like. Has and the other end to the respective inner carriage 18a , b is formed or fixed. The boom webs 30 . 31 are about a connecting element, here a strut 25 , connected with each other. The boom webs 30 . 31 are also on the inner carriage 18a . 18b pivotally arranged or formed ( 10a ).

At the to the rail device 13 directed side of the first inner carriage 18a is a (single) tax role 26 arranged parallel to the top wall 2 or bottom wall 3 is formed or its axis of rotation perpendicular to the top wall 2 or bottom wall 3 is aligned. This tax role 26 is in a corresponding "walking stick-like" cam section 27a . 27b the rail device 13 guided. These are in the rail device 13 directly or preferably in the rail device 13 arranged curved pieces 40 . 41 and a control part 42 undercut grooves as cam sections 27a . 27b as well as a control contour 28 formed into which the tax role 26 engages and is guided in it (see 5 . 6 ).

As can be seen, the cam section is 27a . 27b curved piece preferably formed in the manner of a curved piece and the control contour 28 just.

Will the respective sliding door 8th pressed out laterally from its closed position, move the first outer carriage 12a . 12b guided parallel to the planes E1, E2. Because the tax role 26 becomes when rolling in the cam section 27a unrolled by the installation width B with a component perpendicular to the sliding direction X, so that corresponding to the first and second inner guide carriage 18a . 18b when following the contour in arc shape with a component perpendicular to the planes E1, E2 are moved.

As a result, the associated first inner carriage 18a not only taken in the sliding direction X during opening but also moved from the first plane E1 in the second plane E2, while the tax role 26 in the cam section 27a emotional. Then the tax role moves 26 on the inner carriage 18a parallel to the plane E2 straight in the control contour 28 until the sliding door reaches its maximum open position (see supplementary 2 ).

Become the curve pieces 40 . 41 and the control part 42 separately to the rail device 13 manufactured, can by variation of the control curve geometries 27a . 27b . 28 In the simplest way different installation widths and installation lengths (displacement parallel to plane E2) can be realized. This is a very great advantage of this variant of the invention, since the sliding door fitting is easily adaptable to different furniture dimensions ( 5 . 6 ).

The opening stroke of the first outer and inner guide carriage 12a . 18a is thus through the tax role 26 ( 7a . 7b ) on the inner carriage ( 18a ) certainly. How good in 7 It can be seen, is the tax role 26 preferably on the underside of the first inner guide carriage 18a arranged, with its axis in a slot 29 of the first outer carriage 12a is guided, which is arranged perpendicular to the displacement direction X and to the planes E1, E2. The first part of the opening path is - as explained - by the Arch shape of the cams section 27a in the curve piece 40 specified.

A synchronous (harmonic simultaneous) movement of the second inner carriage 18b on the second outer carriage 12b with the first inner carriage 18a is achieved tax-free by a particularly advantageous multi-joint lever kinematics (arrangement).

This is particularly advantageous since it is possible to dispense not only with a further control roller but in particular with a corresponding second roller track, ie with elements that make it considerably more difficult to adapt the fitting to different installation widths and cabinet sizes. This adjustment is made by the one single control role 26 much easier.

The multi-joint lever kinematics is chosen and designed so that the sliding door 8th during the opening process always from the furniture body 1 moved away and synchronously the first carriage 12a . 18a follows. During the closing process, this movement is reversed accordingly. It also assumes an essential support function.

The multi-joint lever kinematics is determined by several pivot points G1 to G3 and the thrusters S1 and S2 (Figure 8) or run-controlled and is adaptable to different cabinet lengths and installation widths.

The second inner carriage 18b thus requires no second contour path and tax role 26 ,

In a preferred embodiment, the multi-joint arrangement is constructed as follows:
A connecting element such as a strut (preferably a connecting plate) 25 connects the first inner carriage 18a with the second inner carriage 18b ( 7 and 8th ).

At the connecting element 25 are each in the manner of other struts (parallel here) boom 32a and 32b appropriate ( 10a ). The first inner carriage 18a has the hinge point G1 or the joint G1 and the second outer guide carriage 12b the hinge point G2 and the joint G2.

The pivot point G3 is located on the boom 32b , The first pushing device S1 (rollers, roller conveyors) connects the first inner and outer guide carriages 12a . 18a and a second thruster S2 connects the two outer and inner first carriages 12b . 18b , A lower spacer like a spacer 33 ( 8th ) connects the first outer carriage 12a largely rigid with the second outer carriage 12b , ( 7 . 8th ).

A connection lever 34 ( 8th . 9 ) is each pivotally connected to the pivot point G2 (pivot bearing) on the second outer carriage 12b and on the boom 32b connected to the pivot point G3 (pivot bearing). The boom 30 is further pivotable at the pivot point G1 on the first inner guide carriage 18a established.

By the lifting movement of the first inner guide carriage 18a - as a result of the interaction of the tax role 26 with the multi-joint lever kinematics - so when opening the sliding door 8th a pivoting movement of the connecting lever 34 caused ( 9a -C), so that the pivot point G3 in the direction of the door 8th will proceed what the connecting lever 34 parallel to plane E1 and to the strut 25 and with it the booms 31 . 30 this obliquely sets, which in turn makes the sliding door 8th is initially tilted. Upon further opening, the connecting lever 34 further rotated from the position parallel to the plane E1, which then finally at the further extension of the thrusters S1, S2 and the two inner carriage 18a . 18b the strut 25 or the sliding door 8th again parallel to the plane E1.

To implement the closing movement of the sliding door 8th is between the connecting element 25 and the first outer carriage 12a an energy storage, such as a spring 39 , arranged ( 8th . 9 . 10a ).

To stabilize the carriage during the linear movement, ie after the exit of the control roller 26 from the arcuate portion of the cam 27a During this movement is in a particularly advantageous embodiment, a - preferably spring-loaded - locking element 35 ( 7a , b) is provided, which locks the multi-joint lever kinematics during this portion of the movement, so that although the first and second carriages can move together in the X-direction but not relative to each other.

The locking element 35 is designed so that it during the movement of the tax role 26 in the arched section 27a is deactivated or in such a way that it is in the unlocked position, whereas it is during the movement in the straight control contour 28 is activated so that it is in its locking position.

The locking element 35 is designed so that it in a (here T-shaped in cross-section) undercut groove 36 one on the rail device 13 arranged activation element 43 engages over a section of the displacement path X, which preferably until the intervention of the control roller 26 into the straight control contour 28 corresponding path in the X direction corresponds.

It is important and advantageous that the locking element is spring-loaded, such that, after completion of the combined pivoting and longitudinal movement of the sliding door 8th preferably via an inclined contact surface 37 the groove 36 ( 6 ) is raised by its spring preload. The groove 36 extends parallel to the direction of displacement X and is straight.

The locking element 35 is here in a simple and preferred manner as a kind of pin formed with a T-shaped head, which is adapted to a part of the opening path in the undercut groove 36 intervene.

The preferably spring-loaded locking element 35 is here in a preferred embodiment of the spacer plate 33 ( 7 . 12 ), so that its head is spring-loaded in height movable and engages the completion of the pivoting movement, for example, in a franking 38 of the jib 32a one ( 12 ). In this position, the connecting lever can 34 then no longer relative to the spacer plate 33 , so rigid the outer or the rail device 13 directed carriage 12a . 12b stabilized, move. During the straight run of the carriage assembly 10 . 11 This is thus stabilized in itself, which significantly improves the straight-line behavior of the carriage assembly. The carriage arrangement 10 . 11 So runs in this section also very even and very quiet. When closing the door, the locking element runs 35 again on the sloping contact surface 37 up and into the groove 36 and from the franking 38 pulled, so that again a relative movement of the two inner carriage 18a . 18b to the two outer carriages 12a . 12b is possible.

The locking element 35 thus stabilizes the movement behavior of the carriage, in particular in the period in which the tax role 26 from the arcuate cam 27a leaked, in an excellent way, without even affecting the noise adversely.

Preferably, the movement of the sliding door fitting during opening and closing is synchronized with the movement of another fitting on the opposite side in a manner not to be explained in more detail here, for example via levers and rods or the like.

The function of the fitting can be used without structural changes to the fitting itself or to the furniture body both on the cabinet and under the cabinet (by 180 ° rotation of the overall fitting) ( 1 and 3 ).

The use of the overall fitting is customizable by means of mechanical cutting to length of the rail device 13 as longitudinal profiles as well as the control part 42 and a corresponding, adapted to the furniture body width, carriage assembly customizable. By changing the curve pieces 27a . 27b , corresponding positioning of the control part 42 and unilateral position change of the connecting lever 34 at hinge point G3 is another paving width B ( 5 . 6 ) feasible. As a result, a simple length and / or Einbaubreitenkanfektionierung the furniture is guaranteed.
