Description

The invention relates to a guide device for a sliding door, a drive for such a guide device and a piece of furniture, in particular a cabinet with at least one sliding door, which is held and guided by the guide device.

By means of sliding doors can be a piece of furniture, especially a closet, conclude advantageous. To open a cabinet, the sliding doors are pushed aside and do not need to be turned into the room like revolving doors. On the other hand, space is needed for the opening sliding doors, where they can be parked.

From [1], US2014 / 150208A1 , a cabinet with a guide device is known, folded by means of the sliding doors and can be moved parallel to the side wall of the cabinet in a parking space inside. The space reserved for the parking space inside the cabinet, however, is no longer available for the use of the cabinet.

The 2], US8763205B2 discloses a cabinet with a plurality of sliding doors, each held and guided by a slidable along guide rails drive device, so that the sliding doors can be lifted from a cabinet opening and moved laterally. The drive devices include drives and drive arms connected to the sliding doors via connectors. The sliding doors of this cabinet are therefore not transported in a specially designated parking space, but moved in front of an adjacent sliding door. For a cabinet with two sliding doors, the user can therefore push one in front of the other sliding door. The opened sliding door stands therefore in front of the closed sliding door in the field of vision of the user. In cabinets of this type, the sliding doors must therefore be precisely aligned and guided in order to avoid collisions during the displacement and to produce a favorable appearance when the sliding doors have reached the end position.

Due to the relatively complex leadership of the sliding doors, which are lifted when opening from the cabinet opening and moved when closing against the cabinet opening and moved parallel outside this area, resulting for the guide device various tasks that are hardly solved satisfactory in the prior art. In addition to the precise guidance for avoiding collisions and for the desired alignment of the sliding doors, it would be particularly desirable if the sliding doors could be stably guided and held so that vibrations and noises, in particular in the region of the parallel guidance of the sliding doors, can be avoided. Further, it would be desirable if the sliding doors would reliably close the cabinet opening after closing, so that open columns and remaining play the sliding doors can be avoided. A disadvantage of known solutions is also that the sliding doors often can not be completely moved away from the associated cabinet opening, after which access is obstructed in the cabinet opening. Furthermore, a limited displaceability of the sliding door does not allow a maximum size of the cabinet opening to be realized.

The present invention is therefore based on the object to provide an improved guide device and a piece of furniture with at least one sliding door, which advantageously displaceable by means of such a guide device between an open position and a closed position is. Furthermore, an advantageous drive for such a guide device to create.

In particular, a guide device is to be created, by means of which a sliding door held thereby, or generally a flat separating element, can be displaced precisely along a transport path which has at least one curve.

The guide device should in particular allow to enlarge the sliding range of the cabinet doors and thereby completely open an associated cabinet opening and to realize the cabinet opening in maximum size.

By means of the guide device, the held sliding door should be kept as free of play as possible and moved without noise. Furthermore, the sliding door by means of the guide device should be displaced so that a corresponding cabinet opening can be completed reliably.

The guide device should also be simple and take up little space, so that the cabinet space is available to the user without significant restrictions.

Furthermore, the guide device should be able to absorb the load of the sliding door in whole or in part.

A provided with the guide device furniture, in particular a cabinet should therefore be advantageously dimensioned, operated and used.

This object is achieved with a guide device, a guide drive and a piece of furniture with at least one such guide device, which have the features mentioned in claim 1, 11 and 13, respectively. advantageous Embodiments of the invention are specified in further claims.

The guide device, which is provided for holding and guiding a sliding door of a cabinet, by means of which a cabinet opening can be locked, comprises a guide fitting, which is connectable to the sliding door and which can be moved by a first hinge, e.g. a first hinge pin is connected to a first end piece of a guide lever, the second end piece of which is connected by a second hinge, e.g. a second hinge pin is connected to a guide drive having a drive body which holds at least one guide roller which is guided in a guide channel, which runs after installation of the guide device at least in an end region along a curve in the cabinet opening.

When sliding the sliding door against the cabinet opening, the guide drive is driven into the interior of the cabinet and turned the guide lever. The sliding door can therefore be guided laterally in the end position and at the same time against the cabinet opening while the guide drive is running in the end area. As a result, the guide fitting can be guided past the guide drive and driven against the cabinet opening. The guide fitting is therefore moved further in the closing direction of the sliding door than the guide drive. When the guide drive leaves the end area, the guide lever is turned back so that the guide fitting is guided past the guide drive in the other direction and the guide drive is retightened by the guide lever. Also in the opening direction of the sliding door, the guide fitting thus undergoes a further path than the guide drive.

The guide device allows due to the cornering of the guide drive and the rotation of the preferably curved guide lever thus to move the guide fitting and thus the sliding door along the front of the cabinet over a wider area than the guide drive itself is moved. As a result, the cabinet opening can be realized with maximum size. Furthermore, the sliding door can be completely moved away from the cabinet opening, so that the user has unimpeded access to the interior of the cabinet. By means of the curved guide lever, the guide fitting can thus be guided in front of the guide drive during the opening process of the sliding door and the cabinet opening can be completely opened.

In a preferred embodiment, it is provided that the drive body of the guide drive holds two guide rollers arranged one behind the other in the running direction and is additionally connected by a coupling spring to the second end piece of the guide lever.

The coupling spring is preferably a coil spring or a cylinder spring, which is arranged in a recess within the drive body and anchored with a first end piece in the drive body and with the second end piece in the guide lever. Preferably, the coupling spring is in an e.g. cylindrical recess arranged in the drive body coaxial with the hinge pin, which is preferably rotatably mounted in the drive body. In this way, the coupling spring can be integrated to save space in the drive body and coupled with this. Likewise, the coupling of the drive, i. the hinge pin and the coupling spring with the guide lever in a simple manner possible.

The guide drive is rotated when passing through the end portion, the coupling spring tensioned accordingly and a Force or torque exerted on the guide lever. By the torque, the guide arm connected to the second end of the guide lever is rotated against the cabinet and pulled the sliding door against the frame of the cabinet opening, whereby it is sealed tight.

Preferably, the guide lever is curved against the opening direction of the sliding door or in the same direction as the end region of the guide channel extends. For example, the guide lever is L-shaped or sickle-shaped. Due to the curvature of the lever, in the end position of the guide drive, when the first sliding door is open, it can engage the adjacent second sliding door on the edge side and hold the first sliding door in front of the second sliding door.

The curve shape of the end portion of the guide channel is preferably selected such that the guide drive is rotated when passing through the end portion to an angle which is in a range of 65 ° - 180 °. For example, the end region runs at least approximately in a quarter circle arc or semicircular arc. The curve can also run in a spiral and have a steadily reduced curve radius. The curve radius can be linear or non-linear, possibly logarithmically, along the end region reduce. The curve radius can also be reduced linearly in a first curve area and non-linearly in a second curve area. The waveform is chosen such that the desired rotation of the guide drive and thus a desired voltage of the coupling spring results.

The guide channel can be formed by a single guide rail, which is bent in the end region accordingly. However, this is associated with correspondingly high expenditure, if the constancy of the cross section of the guide channel is to be maintained when bending the guide rails.

Preferably, a straight running guide rail is provided, to which a rail element adjoins, which is provided in a guide plate. The end region of the guide channel can be advantageously embossed in the guide plate. Alternatively, the guide plate is cast from metal or plastic. Based on the guide rail and the guide plate, the guide channel can therefore be realized over the entire length with a constant channel cross-section.

In a preferred embodiment, the sliding door or the guide fitting is provided with a door stop, against which a first lever stop provided on the first end piece of the guide lever can be rotated out of the end area at the exit of the guide drive. In a further preferred refinement, the guide drive has a drive stop, against which a second lever stop provided on the second end piece of the guide lever can be rotated out of the end area when the guide drive leaves. The drive stop can be easily formed by the drive body itself. Preferably, these two embodiments with the door stop, the drive stop and the first and second lever stop are provided in combination, by which the range of rotation of the guide lever during the parallel travel relative to the sliding door or the guide fitting on the one hand and the drive is limited.

The door stop and the first lever stop on the one hand and / or the drive stop and the second lever stopper on the other hand are preferably provided such that after the entry of the guide drive into a part of Guide channels, which runs parallel to the front of the cabinet, or after the entry of the guide drive in the straight guide rail of the door stop preferably free of play on the first lever stop and the drive stop preferably rests without play on the second lever stop. Rotation of the guide lever in one direction is therefore limited by the door stop and rotation of the guide lever in the other direction is limited by the drive stop. The sliding door is therefore guided in this position of the guide lever parallel to the cabinet door without lateral displacements perpendicular to the direction and corresponding vibrations can occur.

In a preferred embodiment it is provided that the door stop and the first lever stop and / or the drive stop and the second lever stop are each mounted elastically, elastically formed or connected to one another via an elastic element. In this way, noises are avoided when the mentioned attacks meet. In addition, it is ensured even when manufacturing tolerances that the sliding door is performed without play.

In a further preferred embodiment, the guide drive on at least one support roller which is supported on a running parallel to the guide channel catwalk and preferably integrally formed on the guide rail and the drive plate. This guide drive allows to pick up the load of the sliding door or a part thereof and to guide the sliding door along the guide channel or guide and support channel.

If the guide drive, however, mainly serves the leadership of the sliding door and, for example, engages from below into the guide channel, is characterized by the support roller ensuring that the guide roller always remains engaged in the guide channel. This makes it possible to use a guide channel with channel walls, which have the minimum height required for the guide rollers and thus take up little space.

The guide rollers are preferably held by first bearing shafts, which protrude at least approximately vertically aligned from above or from below into the guide channel. The at least one support roller, however, is held by a second bearing shaft, which is aligned at least approximately horizontally.

The inventive guide drive with at least two guide rollers or with at least two guide rollers and at least one support roller fulfills various functions. The equipment with a coupling spring makes it possible to additionally realize a closing function in addition to the guide function or the guide function and the support function. By means of the closing function, an additional force can be automatically exerted on the sliding door by means of which the sliding door can be moved under the action of force in a desired direction, in particular a direction perpendicular to the cabinet front.

With the guide device according to the invention and the guide drive according to the invention it is thus possible to advantageously develop a cabinet with sliding doors. The sliding doors held by the guide device are guided precisely and stably and kept stable in any position, in particular in the end positions. The sliding doors can be moved away completely from the cabinet openings. In addition, the closing function is improved so that cabinet openings with maximum size can be completed reliably.

The guide device can be arranged at the top or the bottom. In addition, depending on a guide device at the top and the bottom of the sliding door can be provided. If the guiding device e.g. is provided only on the top or bottom of the cabinet, a complementary guide and support device is provided on the bottom or top of the cabinet. If the complementary guiding and carrying device completely assumes the carrying function, the guiding device according to the invention can only provide the guiding function. As mentioned, however, the use of the at least one carrying roller is also advantageous in this case.

Fig. 1a shows a novel cabinet 9 with a cover plate 93 and side plates 94 and two each held by a guide device 6 according to the invention sliding doors 91, 92, each for closing a cabinet opening 90 (see Fig. 1b ) are provided. With a force vector F1 is illustrated that the first sliding door 91 is pulled by means of the guide device 6 against the frame of the cabinet opening 90. The function of the guide device 6 connected to the second sliding door 92 is identical, and therefore, only the guide device 6 connected to the first sliding door 91 will be described below.

Fig. 1b shows the cabinet 9 of Fig. 1a after the first sliding door 91 by means of the associated guide device. 6 lifted off the associated cabinet opening 90 and laterally displaced parallel in front of the second sliding door 92. The guide device 6 comprises a drive 62 which has been guided along a guide rail 68 as far as an intermediate wall 95 and which is connected to the first sliding door 91 via a curved guide lever 63. The first sliding door 91 is held in the parallel displacement in front of the cabinet 9 by means of the guide device 6 such that it can not be moved perpendicular to the direction. In the attempt to move the sliding door 91 perpendicular to the running direction in one or the other direction, a corresponding counterforce F2 or F3 is exerted by the guide device 6.

Fig. 1b further shows that the first sliding door 91 held by the curved guide lever 63 has been completely displaced in front of the second sliding door 92 and, in this position, is aligned coaxially with the second sliding door 92. The cabinet opening 90, which has a maximum size, has therefore been completely exposed. The curved guide lever 63 engages around the second sliding door 92 and can therefore keep the first sliding door 91 outside the area of the associated cabinet opening 90.

Fig. 2a shows the cabinet 9 with the guide device 6 in the configuration of Fig. 1a after removing the first sliding door 91 and a side wall 94 and a section through the center of the cover plate 93. The guide device 6 comprises the straight guide rail 68, which adjoins a guide plate 69, in which the drive 62 has been retracted. The drive 62 is connected to a first end portion of the curved guide lever 63, whose second end piece is connected to a guide fitting 61, from which the first sliding door 91 has been released. On the Bottom of the cabinet 9 is a complementary guide and holding device 1 is provided, which has a complementary drive 11 and associated complementary fittings 10. The complementary drive 11 is displaceable along a curved path such that the complementary fitting 10 is displaced parallel to the guide fitting 61 during the displacement of the sliding door 91. If necessary, the complementary guiding and holding device 1 allows the sliding door 91 to be fully supported, which is why the guide device 6 is not loaded by the weight force of the sliding door 91 in this embodiment of the invention.

Fig. 2b shows the cabinet 9 in the configuration of Fig. 1b after removing the first sliding door 91 and a section through the center of the cover plate 93. The guide fitting 61 and the complementary fitting 10 have been moved along identical curves k parallel to each other. The guide drive 62 is within the space opening 90 in the end stop near the intermediate wall 95, wherein the guide fitting 61 is held by the guide lever 63 in front of the second sliding door 92.

Fig. 3a shows the guide device 6 in the configuration of Fig. 2a with the guide plate 69 with a rail member 690, which adjoins the guide rail 68. By the guide rail 68 and the rail member 690 is a downwardly open guide channel 60 (see Fig. 3c ), in which the guide drive 62 is slidably held. The guide drive 62 is pivotally connected via the almost L-shaped curved guide lever 63 to the guide fitting 61, from which the first sliding door 91 has been released. A first end 63A of the guide lever 63 is connected through a first lever joint, ie by a first hinge pin 613 with the Guide fitting 61 rotatably connected. The guide plate 69 is provided with mounting holes 692 through which mounting screws 699 can be inserted into the cover plate 93.

Fig. 3b shows the guide drive 62, the guide lever 63 and the guide fitting 61, which consists of the guide device of Fig. 3a without changing their mutual position. The illustrated guide drive 62 comprises a drive body 621 with two vertically aligned bearing shafts 626, of which guide rollers 622 are rotatably supported. The drive body 621 is rotatably connected to a second end portion 63B of the guide lever 63 by a second pivot 623 or by a second pivot 623. The guide fitting 61 and the guide drive 62 are therefore rotatable about parallel axes of rotation approximately in the same plane up to a respective stop.

Fig. 3b shows that the guide drive 62 or the drive stop formed by the drive body 621 is rotatable against a second lever stop 632, which is formed by an angled element on the second end 63B of the guide lever 63. Fig. 3d shows that a first lever stopper 631 provided on the first end piece 63A of the guide lever 63 is rotatable against a door stopper 611 formed by an angled member on the guide bracket 61. Schematically, elastic elements 6351, 6352 are shown which can be inserted between the door stop 611 and the first lever stop 631 on the one hand and the drive stop 621 and the second lever stop 632 on the other hand. By the elastic members 6351, 6352, such as leaf springs or elastic plastics or natural rubber manages the impact of the first and second lever stop 631, 632 on the door stop 611 or to dampen the drive stop 621 mechanically and acoustically and to hold these without play together.

Fig. 3c shows the guide device 6 of Fig. 3a from below, looking into the guide rail 68 and the rail member 690 in the guide plate 69, through which a guide channel 60 is formed. The guide channel 60 passes through the guide rail 68 and within the rail member 690 of the guide plate first along an elongated 90 ° curve to the final another small curve of almost 90 ° connects. This curve forms the end region 600 of the guide channel 60. In this end region 600, the guide drive 62 was moved into the cabinet opening 90 and rotated by about 135 °. By the rotation of the guide drive 62, which is connected by a coupling spring 65 with the guide lever 63 (see Fig. 4 ), a force or a torque will be transmitted to the guide lever 63, so that it is further rotated until the sliding door 91 firmly against the frame of the cabinet opening 90.

Fig. 3d shows the guide drive 62, the guide lever 63 and the guide fitting 61 of Fig. 3b from underneath.

Fig. 4 shows the guide drive 62, the guide lever 63 and the guide fitting 61 of Fig. 3b in exploded view. The guide lever 63 occasionally shown is formed almost L-shaped or approximately sickle-shaped and has the first end stop 63A, the first lever stop 631 and a first hinge opening 6301, in which the first hinge pin 613 is inserted, which passed through an opening 610 in the guide fitting 61 therethrough becomes. The guide fitting 61 is formed in the shape of an angle. The first leg of the angle or the guide fitting 61 forms a connectable to the sliding door 91 fitting plate 617, which is provided with mounting holes 6171. On the second leg of the angle are two Openings 610 provided in the optional hinge pin 613 is used. In the guide fitting 61 of the first sliding door 91, the hinge pin 613 is inserted into the right opening 610, and in the guide fitting of the second sliding door 91, the hinge pin is inserted into the left opening 610. The same guide device 6 can therefore be assembled so that it can be used on both sides of the cabinet 9 for each of the sliding doors 91, 92.

At the second end piece 63B, the guide lever 63 has the second lever stopper 632 and a second hinge hole 6302 into which the second hinge pin 623 which is supported in the drive body 621 of the guide disk 62 in a bearing cylinder 6211 can be inserted. Concentric with the bearing cylinder 6211, the bearing housing 621 has an annular receiving opening 6210 into which the illustrated coupling spring 65 can be inserted, which has a winding package 651 with two spring end pieces 651 and 652. The first spring end piece 652 is insertable into a coupling opening 6215 in the drive body 610 (see FIG Fig. 7b ). The second spring end 653 is insertable into a spring opening 6305 in the second end 63B of the guide lever 63. The guide drive 62 is therefore connected on the one hand by the second hinge pin 623 and on the other hand by the coupling spring 65 with the guide lever 63. Upon rotation of the guide drive 62 (to the right), the coupling spring 65 is tensioned and a torque is exerted on the guide lever 63.

Fig. 5a shows the guide device 6 in the configuration of the cabinet 9 of Fig. 1a from below with the sliding door 91 connected to the guide fitting 61 in the end position of the guide drive 62, as in the FIGS. 3a-d is shown. The guide lever 63 was moved into the cabinet opening 90 together with the guide drive 62 and rotated counterclockwise, whereby the guide fitting 61 was guided to the right against the cabinet 9. As a result of the rotation of the guide drive 62 when passing through the end region 600 of the guide channel 60, the coupling spring 65 has been tensioned, for which reason a corresponding torque M1 acts on the guide lever 63. By the guide lever 63, a corresponding force F1 is transmitted to the guide fitting 61, with the sliding door 91 is pulled almost vertically against the cabinet 9.

In Fig. 5a Furthermore, the distance d1 is shown, by which the guide fitting 61 has been guided past the guide drive 62 to the right.

Fig. 5b shows the guide device 6 of Fig. 5a in the process of opening the sliding door 91 just before the exit of the guide drive 62 from the guide plate 69 and the entrance to the guide rail 68. The sliding door 91 has been lifted from the cabinet opening 90 and the guide fitting 61 has already passed the guide drive 62 to the left.

Fig. 5c shows the guide device 6 of Fig. 5b after the entrance of the guide drive 62 in the shortened guide rail 68 and the shift to the end stop on the intermediate wall 95. The first sliding door 91 was completely moved away from the associated cabinet opening 90 and moved in front of the second sliding door 92. By the curved guide lever 63 of the guide fitting 61 is held by the distance d2 in front of the guide drive 62. The guide fitting 61 has therefore traveled a distance d = d1 + d2 more than the guide drive 62 in the direction of the guide rail 68 when the first sliding door 91 is displaced.

After entering the guide rail 68, the guide drive 62 is aligned parallel to the longitudinal axis x of the guide rail 68. The second lever stop 632 abuts on the drive stop or on the drive body 621 and can not be rotated further to the left in the indicated direction R2. At the same time, the first lever stop 631 bears against the door stop 611 and can no longer be turned to the right in the opposite direction R1. The guide lever 63 is thus held against rotation by the door stop 611 and the drive stop 621 in both directions R1 and R2. The sliding door 91 can therefore only be displaced axially along a displacement axis y which runs parallel to the longitudinal axis x of the guide rail 68. Shifts perpendicular to the displacement axis y and corresponding vibrations and noise are excluded.

Fig. 6 shows the guide device 6 in a preferred embodiment from below with view approximately along the longitudinal axis x of the guide rail 68. In this embodiment, the guide drive 62 is provided with a support wheel 628 which can roll on a horizontally oriented walkway 688, 698, in addition to the Guide rail 68 and the guide plate 69 is provided parallel to the guide channel 60 extending. The drive body 621 has an additional holding part 6218, which holds a second bearing shaft 627, by means of which the support wheel 628 is rotatably mounted (see also Fig. 7a ). By the support wheel 628, the guide drive 62 is always maintained at the same height, thereby ensuring the constant engagement of the guide rollers 622 in the guide channel 60. Thus, it is possible to use a guide channel 60 or a guide rail 68 and a rail member 690, which have only a small wall height. In addition, the guide drive 62 may carry the load of the sliding door 91 or a part thereof.

Next shows Fig. 6 in that the second lever stop 632 is not provided in one piece on the guide lever 63 in this embodiment. Instead, a cylindrical lever stop 632 is attached to the guide lever 63 by means of a rivet. The cylindrical lever stop 632 is preferably made of an elastic material, so that a play-free connection can be realized and noise during operation of the guide device 6 can be avoided. The door stop 611 and the first and second lever stop 631, 632 can therefore be integrally formed or otherwise secured.

Fig. 7a shows that from the guide device 6 of Fig. 6 removed guide drive 62, which has 2 guide rollers 622 and a support roller 628, which are held by first and second bearing shafts 626, 627.

Fig. 7b shows the guide drive 62 of Fig. 7a with a section along the line AA, which passes through the receiving opening 6210 for the coupling spring 65 and through the coupling opening 6215, in which the first spring end 652 is anchored. The second spring end 653 protrudes as well as the second hinge pin 623 from the receiving opening 6210.

The guide device 6 can also be further developed such that individual device parts, in particular the drive stop 621, the door stop 611, the first lever stop 631 and / or the second lever stop 632 are adjustable, so that the areas in which the guide fitting 61 against the guide lever 63 and the guide drive 62 against the guide planes 63 are rotatable, can be adjusted. It can also be provided that the bearing shaft 627, which holds the support wheel 628, can be moved parallel in height. For example, the Bearing shaft 627 are stored in a carriage which is displaceable along the holding part 6218.
