Description

Technical Field

[0001] The invention relates to a guide system for guiding at least one movably mounted door leaf relative to at least one fixed furniture part, the guide system comprising:

[0002] - at least one guide rail which can be arranged on said at least one furniture component;

[0003] - at least one guide device, on which the at least one door leaf can be pivotably mounted, the at least one guide device being movably mounted along the at least one guide rail between an inward end position and an outward end position;

[0004] - at least one shutter for covering at least one end side of the at least one guide rail, the at least one shutter being movable between at least a first operating position, in which the shutter at least partially covers the at least one end side of the at least one guide rail, and a second operating position, in which the at least one shutter at least partially releases the at least one end side; and

[0005] At least one actuating device, by means of which the at least one shutter can be moved at least from the first operating position into the second operating position.

[0006] The invention furthermore relates to a method for moving at least one movably mounted door leaf relative to at least one stationary furniture part by means of at least one guide system of the type to be described.

[0007] Finally, the invention also relates to a piece of furniture having at least one door leaf, in particular a sliding door or a folding sliding door, a fixed furniture part and at least one guide system to be described. Background Art

[0008] Furniture with a movably mounted cover for covering a gap between two furniture parts is known, for example, from EP 2 899 344 A1, EP 2 071 108 A1 and WO 99 / 23337 A1.

[0009] DE102014018682B3 shows a piece of furniture with a furniture body and a plurality of folding door elements, which can be transferred from a first position covering the furniture body to a second position, in which the folded folding door elements are accommodated in a storage compartment above the furniture body. The folding door element can be raised relative to the furniture body by a first electric drive from the first position, and then the folding door element can be moved into the storage compartment above the furniture body by a second electric drive. In addition, a movably supported closing cover is provided, which is operated by a push chain that can be driven by a second electric drive. When the folding door element is located inside the storage compartment, the storage compartment above the furniture body can be closed by the closing cover.

[0010] By means of a shutter of such a guide system, a receiving compartment for receiving at least one door leaf and the end side of a guide rail for movably supporting the door leaf, which is located in the receiving compartment, can be at least partially covered. By movably supporting the shutter, the shutter partially covers the receiving compartment in a first operating position and allows the door leaf to be moved out in a second operating position. However, when the door leaf is moved out, there is a significant risk that the door leaf and the shutter may collide with each other or get stuck with each other. Summary of the invention

[0011] The object of the present invention is to provide a guide system of the type mentioned at the outset which avoids the above-mentioned disadvantages and in particular improves the control of the movement of the shutter.

[0012] According to the present invention, it is provided that at least one coupling device is provided, through which the at least one guiding device can be releasably coupled to the at least one operating device on a section of the at least one guide rail upstream of the extended terminal position, preferably immediately upstream, and the at least one operating device can be driven by the at least one guiding device in a coupled state with the at least one guiding device to move the at least one baffle from the first operating position to the second operating position.

[0013] In other words, the guide device, on which the at least one door leaf can be supported, can move freely over a large part of the movement of the guide device between the extended end position and the extended end position, and is only releasably coupled to the actuating device by the coupling device just before reaching the extended end position in order to actuate the movement of the shutter. In this way, it is ensured that the shutter is moved to the second operating position before the guide device reaches its extended end position. As a result, a collision between the shutter and the extended door leaf can be effectively prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1a A perspective view of a piece of furniture 1 is shown, which has a furniture body 2 and door panels 3a, 3b, 4 that are movable relative to the furniture body 2. The door panels 3a, 3b are hingedly connected to each other via a vertically extending axis. The door panels 3a, 3b, 4 can be formed as sliding doors or folding sliding doors.

[0023] The door leaves 3a, 3b are supported movably by a guide system 8 between a first position, in which the door leaves 3a, 3b are oriented substantially coplanarly with one another, and a second position, in which the door leaves 3a, 3b are oriented substantially parallel to one another. In the first (coplanar) position, the door leaves 3a, 3b substantially completely cover the furniture carcass 2. In the second (parallel) position, the door leaves 3a, 3b can be pushed into the receiving compartment 5a of the furniture carcass 2. The receiving compartment 5a is formed in the illustrated embodiment by two side walls 6a, 6b that are substantially parallel to one another and spaced apart.

[0024] The guide system 8 comprises a longitudinal rail 9a for guiding the door leaves 3a, 3b, which is formed for guiding the door leaves 3a, 3b along the end side 2a of the furniture body 2. The door leaves 3a, 3b can be guided along the side wall 6a of the furniture body 2 by means of a guide rail 9b extending transversely to the longitudinal rail 9a.

[0025] On the contrary, the door leaf 4 can be formed as a single door leaf 4, which can be oriented coplanarly with the other two door leaves 3a, 3b in the first position. The door leaf 4 can be oriented substantially parallel to the plate-shaped furniture component 7a in the second position, in which the door leaf 4 can be pushed along the guide rail 9c into another receiving compartment 5b of the furniture body 2. The receiving compartment 5b for receiving the door leaf 4 is formed by two substantially parallel, spaced apart, fixed plate-shaped furniture components 7a, 7b.

[0026] Figure 1b Display according to Figure 1a Furniture 1, wherein door panels 3a, 3b are accommodated in a receiving compartment 5a in a position parallel to one another. In contrast, door panel 4 is pushed into receiving compartment 5b, which is formed by two plate-shaped furniture parts 7a, 7b. Furniture 1 comprises at least one interior space 2a which can be at least partially covered by at least one door panel 4, in which at least one interior space 2a, for example, kitchen furniture and kitchen utensils can be arranged.

[0027] Figure 2a The front view shows a door leaf 4 which is oriented parallel to the plate-shaped furniture component 7a and is completely located in the storage compartment 5b. A vertically extending gap 10 is formed between the furniture component 7a and the door leaf 4, which gap 10 can be covered at least partially by a movably supported cover 11. For the sake of simplicity, the operation of the cover 11 will be described in conjunction with the door leaf 4 and the storage compartment 5b. However, the cover 11 can of course also be used in conjunction with two other door leaves 3a, 3b in another storage compartment 5a.

[0028] A gap 10 is located between the furniture part 7a and the door leaf 4, which gap 10 has a width of, for example, about 3 cm. This gap 10 can be covered by a shield 11 in the position where the door leaf 4 is pushed into the receiving compartment 5b. The shield 11 can have a length substantially equal to the height of the door leaf 4.

[0029] Figure 2b Shown in top view Figure 2a The door leaf 4 is completely immersed in the receiving compartment 5b formed by the fixed furniture parts 7a, 7b. The guide rail 9c is fixed to the furniture part 7a, which guide rail has a front side 15. The door leaf 4 is pivotably supported about a vertically extending axis on the guide device 12 ( Figure 3a ) on a vertically extending carrier 12a which can be displaced along the guide rail 9c. Figure 2b In the embodiment shown in FIG. 1 , the carrier 12 a of the guide device 12 is in the retracted end position. A mounting part 13 is fastened in the front region of the furniture part 7 a , wherein the cover 11 is mounted on the mounting part 13 so as to be pivotable about a vertically extending axis 14 .

[0030] The shield 11 is provided for at least partially covering the gap 10 and / or the front end side 15 of the guide rail 9c. The shield 11 is movably supported between at least a first operating position, in which the shield 11 at least partially covers the end side 15 of at least one guide rail 9c, and a second operating position, in which the at least one shield 11 at least partially releases the at least one end side 15.

[0031] Figure 2c Shown in enlarged view Figure 2b 9a. The mounting part 13 is fixed to the furniture part 7a, and the cover 11 can be pivoted relative to the mounting part 13 about a vertically extending axis 14. The cover 11 can include a first plate 11a and a second plate 11b extending laterally from the first plate 11a. In a first operating position of the cover 11, which covers the gap 10 and / or the end side 15 of the guide rail 9c, the first plate 11a is oriented essentially perpendicularly to the plate-shaped furniture part 7a.

[0032] Figures 3a to 3c A piece of furniture 1 is shown, which has a door leaf 4 and a guide system 8 for guiding the door leaf 4. The guide system 8 comprises at least one guide rail 9c that can be fixed to a fixed furniture part 7a, along which a guide device 12 is displaceably supported by a vertically extending elongated carrier 12a. The guide device 12 is movably supported along the at least one guide rail 9c between an inward end position and an outward end position. The at least one door leaf 4 is connected in an articulated manner to the carrier 12a.

[0033] According to one embodiment, the guiding system 8 may be configured as follows:

[0034] - comprises at least one ejection device 17 - preferably releasably lockable - for ejecting the at least one guide device 12 from the retracted end position in the direction of the extended end position; and / or

[0035] - comprising at least one compensation device 16, the at least one compensation device being used to compensate for the turning moment caused by the restoring moment of the at least one guide device 12 around the turning axis, preferably, the at least one compensation device 16 comprises a scissors mechanism 16a and / or a cable device 16b; and / or

[0036] - comprises at least one further guide rail 9d, the guide rails 9c, 9d being provided so as to be fastened to the stationary furniture part 7a at a distance from one another in the height direction, the at least one guide device 12 being preferably mounted movably along the guide rails 9c, 9d.

[0037] Figure 3b Show in another perspective Figure 3a The carrier 12a of the guide device 12 is mounted movably along the guide rails 9c, 9d in the depth direction (Z) of the piece of furniture 1 between an inward end position and an outward end position.

[0038] Figure 3c Shown in enlarged view Figure 3b The guide device 12 comprises at least one rolling body 12b, by which the carrier 12a is displaceably supported along the at least one guide rail 9c. The guide device 12 is in an extended end position, in which the carrier 12a is held in position by a releasable holding device 20.

[0039] The guide system 8 comprises an assembly part 13 which can be fixed on a fixed furniture part 7a, a coupling device 19, an operating device 18 and a retaining device 20 being supported on the assembly part, the coupling device having a pivotable coupling rod 19a for releasably coupling with the guide device 12, the operating device having a linearly movable slide 18a for operating the baffle 11; the retaining device being used to hold the guide device 12 in the extended terminal position.

[0040] Through the coupling device 19, the guiding device 12 can be releasably coupled to the operating device 18 on a section of the guide rail 9c upstream of the extended terminal position, preferably immediately upstream, wherein the operating device 18 can be driven by the guiding device 12 in the coupled state with the guiding device 12 to move the baffle 11 from the first operating position to the second operating position.

[0041] According to one embodiment, it can be arranged as follows: the guiding device 12 and the operating device 18 are decoupled from each other in the extended end position and / or in another section between the extended end position and the section (the section is upstream, preferably immediately upstream, of the extended end position, in which the guiding device 12 and the operating device 18 can be releasably coupled to each other).

[0042] Figure 4aThe guide device 12 is shown with a carrier 12a, which is located on a section upstream of the extended end position. The door leaf 4 is oriented substantially parallel to the fixed furniture part 7a. The mounting part 13 arranged on the fixed furniture part 7a can be seen, on which the coupling device 19, the holding device 20 and the actuating device 18 are supported. The shutter 11 is connected to the mounting part 13 in an articulated manner, preferably by at least one hinge 21 ( Figure 6a ) hinged connection.

[0043] According to one embodiment, it may be provided that the coupling device 19:

[0044] - comprising - preferably about an axis of rotation 19d ( Figure 6a ) - at least one pivotably supported coupling rod 19a; and / or

[0045] - comprises at least one recess 19b, preferably funnel-shaped, which can be releasably coupled to an actuator 12c arranged on the at least one guide device 12; and / or

[0046] - at least one guide contour 19c is provided, preferably in the form of a circular arc ( Figure 4b ), the at least one coupling device 19 is supported movably along the at least one guide contour.

[0047] In the displayed Figure 4a In the embodiment, since the actuator 12c of the guide device 12 is spaced apart from the coupling rod 19a of the coupling device 19, the guide device 12 is in an uncoupled state with respect to the coupling device 19. Here, the shutter 11 is in a first operating position, in which the end side 15 of the guide rail 9c and / or the gap 10 formed between the fixed furniture part 7a and the door leaf 4 can be covered.

[0048] As the guide device 12 continues to move, the at least one rolling element 12b of the carrier 12a moves along the guide rail 9c until the actuator 12c of the carrier 12a enters the recess 19b of the coupling rod 19a of the coupling device 19. The coupling rod 19a then rotates around the rotation axis 19d ( Figure 6a ) pivots, thereby triggering the operating device 18.

[0049] According to one embodiment, it may be provided that the operating device 18:

[0050] - comprises at least one linearly movable slide 18a; and / or

[0051] - connected, preferably articulated, to the at least one coupling device 19; and / or

[0052] - comprises at least one longitudinal guide 18c, by means of which the maneuvering device 18 is movable at least in a direction parallel to the longitudinal direction (L) of the at least one guide rail 9c; and / or

[0053] - comprises at least one inclined surface 18 b for manipulating the at least one shutter 11 .

[0054] According to one embodiment, at least one adjustment device 23 may be provided, by which the position of the at least one fitting part 13 relative to the at least one guide rail 9c may be adjusted, preferably in a direction parallel to the longitudinal direction (L) of the at least one guide rail 9c.

[0055] Figure 4b The guide device 12 is shown in a coupled state with the coupling device 19, wherein the actuator 12c of the guide device 12 is located in the recess 19b of the coupling rod 19a of the coupling device 19. It can be seen that the slide 18a of the operating device 18 is moved from the coupling rod 19a to the guide device 12 by the pivoting movement of the coupling rod 19a. Figure 4a to Figure 4b Linear movement, wherein the shutter 11 is pivoted by means of the inclined surface 18 b of the slide 18 a from a first operating position into a second operating position in which the shutter 11 at least partially releases the gap 10 and / or the front end side 15 of the guide rail 9 c.

[0056] Figure 5a The guide device 12 can be disengaged from the coupling device 19 again when it is moved further in the direction of the extended end position, because the actuator 12c of the guide device 12 has been released from the coupling rod 19a of the coupling device 19. The holding device 20 now becomes effective, by which the guide device 12 is held in position relative to the at least one guide rail 9c in the extended end position. It is preferably provided that the guide device 12 can be held by the holding device 20 starting from the section immediately upstream of the extended end position - for example by means of a spring element 20c ( Figure 5b ) force - is driven into the extended end position.

[0057] According to one embodiment, it may be provided that the holding device 20:

[0058] - comprises at least one turning lever 20a which is pivotably supported, preferably about an axis of rotation; and / or

[0059] - comprises at least one recess 20b, preferably funnel-shaped, which can be releasably coupled to an actuator 12c arranged on the at least one guide device 12; and / or

[0060] - comprises at least one spring element 20 c for applying a force to the at least one retaining device 20 .

[0061] Figure 5b It is shown that the guide device 12 with the carrier 12 a is moved into an extended end position by the force of the spring element 20 c of the holding device 20 , wherein the guide device 12 is held in position with a predetermined holding force in the extended end position.

[0062] Figures 6a to 6h The movement of the guide device 12 up to the extended end position is shown in chronological order. Figure 6a The mounting part 13 is shown, on which the coupling device 19 , the actuating device 18 and the holding device 20 are arranged.

[0063] The shutter 11 is hingedly connected to the mounting part 13 via at least one hinge 21. The hinge 21 for supporting the shutter 11 may include a reset device 21a, which preferably has a reset spring, and the shutter 11 can be reset from the second operating position to the first operating position via the reset device.

[0064] For the sake of clarity, only the actuator 12c is shown for the guide device 12, which, when the guide device 12 moves in the direction of the extended end position, approaches the coupling device 19 and finally interacts with the coupling rod 19a of the coupling device 19 by moving the actuator 12c into the recess 19b of the coupling rod 19a. Figure 6a Displayed in.

[0065] When the actuator 12c continues to move, the coupling rod 19a of the coupling device 19 pivots about the rotation axis 19d, thereby also triggering the operating device 18 ( Figure 6b ). In the embodiment shown, the slide 18a of the actuating device 18 is connected in an articulated manner to the coupling rod 19a of the coupling device 19, wherein the slide 18 can be linearly displaced by a pivoting movement of the coupling rod 19a. This ensures that the shutter 11 is moved before the guide device 12 reaches the extended end position.

[0066] When the actuator 12c moves further in the direction of the extended end position, the shutter 11 is actuated by the slide 18a. The linear mobility of the slide 18a is controlled by the longitudinal guide 18c ( Figure 6c , 6d )accomplish.

[0067] When the actuator 12c moves further in the direction of the extended end position, the actuator 12c is disengaged from the coupling device 19 again, wherein the actuator 12c is neither engaged with the coupling device 19 nor with the holding device 20 ( Figure 6e ).

[0068] exist Figure 6f In the embodiment, the actuator 12c can be coupled to the holding device 20 by moving the actuator 12c into the recess 20b of the tilting lever 20a. The further movement of the actuator 12c in the direction of the extended end position causes the tilting lever 20a of the holding device 20 to pivot ( Figure 6g ), wherein the actuator 12c (and therefore the entire guide device 20 with the carrier 20a and the door leaf 4 supported on the carrier 20a) is driven by the force of the spring element 20c of the holding device 20 until the extended end position ( Figure 6h ).

[0069] The method for moving at least one movably mounted door leaf 4 relative to at least one fixed furniture part 7a by means of at least one guide system 8 is characterized by the following method steps:

[0070] - moving the at least one guide device 12 along the at least one guide rail 9c from the inward end position in the direction of the outward end position;

[0071] - releasably coupling the at least one guide device 12 to the at least one actuating device 18 via the at least one coupling device 19 in a subsection of the at least one guide rail 9c that is upstream, preferably immediately upstream, of the extended end position;

[0072] - the at least one operating device 18 is driven by the at least one guiding device 12 in the direction of the extended end position when coupled to the at least one guiding device 12; and

[0073] The at least one shutter 11 is moved by means of the at least one actuating device 18 from a first operating position into a second operating position.

[0074] In a further method step, provision can be made for the at least one guide device 12 to be disengaged from the at least one actuating device 18 during the further movement in the direction of the extended end position.

[0075] According to one embodiment, it can be provided that at least one holding device 20 is provided, which is used to hold the at least one guide device 12 in the extended terminal position relative to the at least one guide rail 9c, and in another method step, the at least one guide device 12 is held by the at least one holding device 20 in the extended terminal position.

[0076] In another method step, the at least one guiding device 12 moves along the at least one guide rail 9c from the extended terminal position in the direction of the retracted terminal position, wherein the at least one guiding device 12 is releasably coupled to the at least one operating device 18 via the at least one coupling device 19, and the at least one operating device 18 is driven by the at least one guiding device 12 in the direction of the retracted terminal position when coupled to the at least one guiding device 12.

[0077] Figure 7a A part of the guide system 8 is shown in an exploded view. A mounting part 13 can be fastened to a fixed furniture part 7a, wherein a coupling device 19 with a coupling rod 19a, an actuating device 18 with a slide 18a and a holding device 20 with a tilting lever 20a are supported on the mounting part 13. The mounting part 13 contains a—preferably arc-shaped—guide contour 19c, which serves to movably support the coupling device 19. Guide elements 22 are also provided, which are movably guided in longitudinal guides 18c of the slide 18a.

[0078] In order to pass Figure 3c The adjustment device 23 shown in the figure enables the adjustability of the mounting part 13 relative to the guide rail 9c, and the mounting part 13 is mounted on the fixed furniture part 7a via a holding part 24. The holding part 24 comprises at least one fixing part 4a, which is used for mounting on the fixed furniture part 7a, wherein the at least one fixing part 4a can be formed, for example, as a hole for a screw to pass through.

[0079] The holding part 24 comprises at least one guide plate 24b, wherein the plate-shaped mounting part 13 is movably guided between the fixed furniture part 7a and the guide plate 24b in the assembled state and can be adjusted in the longitudinal direction (L) of the guide rail 9c by the adjusting device 23. The mounting part 13 has a recess 25, into which an adjusting part adjustable by the adjusting device 23 engages, so that the mounting part 13 is displaced relative to the guide rail 9c. In this way, the extended end position of the guide device 12 can be variably adjusted by the adjusting device 23.
