The present invention relates to a guide system for guiding at least one movably-supported door wing relative to at least one stationary furniture part. The guide system includes: at least one guide rail configured to be arranged on the at least one furniture part, and at least one guiding device on which the at least one door wing can be pivotally supported, the at least one guiding device being movably supported between a retracted end position and an extended end position along the at least one guide rail. At least one cover is configured to cover at least one front face of the at least one guide rail, the at least one cover being movable at least between a first operating position, in which the cover at least partially covers the at least one front face of the at least one guide rail, and a second operating position, in which the at least one cover at least partially reveals the at least one front face, and at least one actuating device for moving the at least one cover at least from the first operating position into the second operating position.
Moreover, the invention concerns a method for moving at least one movably-supported door wing relative to a stationary furniture part by means of the at least one guide system of the type to be described.
Finally, the invention relates to an item of furniture comprising at least one door wing, in particular a sliding door or a folding-sliding door, a stationary furniture part, and at least one guide system of the type to be described.
Items of furniture with a movably-supported cover for covering a gap located between two furniture parts have been known, for example, from EP 2 899 344 A1, EP 2 071 108 A1 and WO 99/23337 A1.
DE 10 2014 018 682 B3 discloses an item of furniture comprising a furniture carcass and a plurality of folding-door elements which can be transferred from a first position, in which the furniture carcass can be covered, into a second position, in which the folded folding-door elements can be received in an upper receiving compartment of the furniture carcass. The folding-door elements can be lifted from the first position relative to the furniture carcass by a first electric drive. Subsequently, the folding-door elements can be moved into the upper receiving compartment of the furniture carcass by a second electric drive. Moreover, a movably-supported closing flap is provided which can be actuated by a drive chain configured to be driven by the second electric drive. By the closing flap, the upper receiving compartment of the furniture carcass can be closed when the folding-door elements are located within the receiving compartment.
By the cover of such a guide system, a receiving compartment for receiving the at least one door wing and a front face of the guide rail for displaceably supporting the door wing can be at least partially covered, the front face of the guide rail being located within the receiving compartment. By movably supporting the cover, it can be provided that the cover partially covers the receiving compartment in the first operating position, and an extension movement of the door wing can be made possible in the second operating position. However, upon the extension movement of the door wing, there is the considerable danger that the door wing and the cover can collide with each other or can get jammed with each other.
It is an object of the present invention to propose a guide system of the type mentioned in the introductory part, thereby avoiding the above-discussed drawbacks and, in particular, to improve the control of a movement of the cover.
According to the invention, at least one coupling device is provided, the at least one coupling device being configured to releasably couple the at least one guiding device to the at least one actuating device in a partial section of the at least one guide rail, the partial section preceding, preferably immediately, the extended end position. The at least one actuating device, in a coupled condition with the at least one guiding device, can be entrained by the at least one guiding device so as to move the at least one cover from the first operating position into the second operating position.
In other words, the guiding device, on which the at least one door wing can be supported, is freely movable over a majority of its movement path between the retracted end position and the extended end position, and is only releasably coupled shortly before reaching the extended end position via the coupling device to the actuating device for actuating a movement of the cover. In this way, it can be ensured that the cover is moved into the second operating position before the guiding device reaches its extended end position. As a result, a collision between the cover and the extending door wing can be effectively prevented.
Further details and advantages of the present invention result from the following description of figures.
The door wings 3a, 3b are movably supported by a guide system 8 between a first position, in which the door wings 3a, 3b are aligned substantially coplanar to one another, and a second position, in which the door wings 3a, 3b are aligned substantially parallel to one another. In the first (coplanar) position, the door wings 3a, 3b substantially entirely cover the furniture carcass 2. In the second (parallel) position, the door wings 3a, 3b can be inserted into a receiving compartment 5a of the furniture carcass 2. In the shown embodiment, the receiving compartment 5a is formed by two sidewalls 6a, 6b mutually spaced from each other in a substantially parallel relationship.
The guide system 8 includes a longitudinal rail 9a for guiding the door wings 3a, 3b. The longitudinal rail 9a is configured so as to guide the door wings 3a, 3b along a front face 2a of the furniture carcass 2. By a guide rail 9b extending transversely to the longitudinal rail 9a, the door wings 3a, 3b can be guided along the sidewall 6a of the furniture carcass 2.
On the contrary, the door wing 4 can be in the form of a single door wing 4 configured to be aligned coplanar to the two other door wings 3a, 3b in a first position. In a second position, in which the door wing 4 can be aligned substantially parallel to a panel-shaped furniture part 7a, the door wing 4 can be inserted along a guide rail 9c into a further receiving compartment 5b of the furniture carcass 2. The receiving compartment 5b for receiving the door wing 4 is formed by two stationary, panel-shaped furniture parts 7a, 7b which are mutually spaced from each other in a substantially parallel relationship.
The gap 10 is arranged between the furniture part 7a and the door wing 4, the gap 10 having a width of approximately 3 cm for example. The gap 10 can be covered by the cover 11 in a position in which the door wing 4 is inserted within the receiving compartment 5b. The cover 11 can have a length corresponding substantially to a height of the door wing 4.
The cover 11 is provided so as to at least partially cover the gap 10 and/or the front face 15 of the guide rail 9c. The cover 11 is movably supported at least between a first operating position, in which the cover 11 at least partially covers the front face 15 of the at least one guide rail 9c, and a second position, in which the at least one cover 11 at least partially reveals the at least one front face 15.
According to an embodiment, it can be provided that the guiding device 8
The guide system 8 includes a mounting member 13 configured to be fixed to the stationary furniture part 7a. A coupling device 19 having a pivotable coupling lever 19a for releasably coupling to the guiding device 12, an actuating device 18 having a linearly displaceable slider 18a for actuating the cover 11, and the holding device 20 for holding the guiding device 12 in the extended end position are supported on the mounting member 13.
By the coupling device 19, the guiding device 12 can be releasably coupled to the actuating device 18 in a partial section of the guide rail 9c, the partial section preceding, preferably immediately, the extended end position. The actuating device 18, in a coupled condition with the guiding device 12, can be entrained by the guiding device 12 so as to move the cover 11 from the first operating position into the second operating position.
According to an embodiment, it can be provided that the at least one guiding device and the at least one actuating device, in the extended end position and/or in a further partial section between the retracted end position and the extended end position, are decoupled from one another, the further partial section, preferably immediately, preceding the partial section in which the at least one guiding device can be releasably coupled to the at least one actuating device.
According to an embodiment, it can be provided that the coupling device 19
In the shown
Upon a continued movement of the guiding device 12, the at least one rolling body 12b of the carrier 12a is moved along the guide rail 9c, until the actuator 12c of the carrier 12a enters the notch 19b of the coupling lever 19a of the coupling device 19. The coupling lever 19a is then pivoted about the pivoting axis 19d (
According to an embodiment, it can be provided that the actuating device 18
According to an embodiment, at least one adjustment device 23 can be provided for adjusting a position of the at least one mounting member 13 relative to the at least one guide rail 9c, preferably in a direction extending parallel to a longitudinal direction (L) of the at least one guide rail 9c.
According to an embodiment, it can be provided that the holding device 20
The cover 11 is hingedly connected to the mounting member 13 via at least one hinge 21. The hinge 21 for supporting the cover 11 can include a return device 21a, preferably having a return spring, configured to return the cover 11 from the second operating position into the first operating position.
For the sake of clarity, only the actuator 12c from the guiding device 12 is shown. The actuator 12c approaches towards the coupling device 19 upon a movement of the guiding device 12 in a direction of the extended end position, and eventually co-operates with the coupling lever 19a of the coupling device 19, namely in that the actuator 12c enters into the notch 19b of the coupling lever 19a. This situation is shown in
Upon a continued movement of the actuator 12c, the coupling lever 19a of the coupling device 19 is pivoted about the pivoting axis 19d. As a result, the actuating device 18 for actuating the cover 11 can also be triggered (
Upon a continued movement of the actuator 12c in a direction of the extended end position, the cover 11 is actuated by the slider 18a. The linear displaceability of the slider 18a can be made possible by the longitudinal guides 18c (
Upon a continued movement of the actuator 12c in a direction of the extended end position, the actuator 12c is again decoupled from the coupling device 19. Accordingly, the actuator 12c is neither engaged with the coupling device 19 nor with the holding device 20 (
In
The method for moving at least one movably-supported door wing 4 relative to at least one stationary furniture part 7a by at least one guide system 8 is characterized by the following method steps:
In a further method step, it can be provided that the at least one guiding device 12, upon a continued movement in a direction of the extended end position, is decoupled from the at least one actuating device 18.
According to an embodiment, it can be provided that at least one holding device 20 is provided so as to hold the at least one guiding device 12 relative to the at least one guide rail 9c in the extended end position. In a further method step, the at least one guiding device 12 is held in the extended end position by the at least one holding device 20.
In a further method step, the at least one guiding device 12 is moved from the extended end position in a direction of the retracted end position along the at least one guide rail 9c. The at least one guiding device 12 is releasably coupled to the at least one actuating device 18 by the at least one coupling device 19. The at least one actuating device 18, in a coupled condition with the at least one guiding device 12, is entrained in a direction of the retracted end position by the at least one guiding device 12.
In order to provide an adjustment of the mounting member 13 relative to the guide rail 9c by the adjustment device 23 shown in
The holding portion 24 includes at least one guide limb 24b, and the panel-shaped mounting member 13 can be displaceably guided between the stationary furniture part 7a and the guide limb 24b in a mounted condition. The mounting member 13 is adjustable in the longitudinal direction (L) to the guide rail 9c by the adjustment device 23. The mounting member 13 includes a recess 25, and a setting member configured to be adjusted by the adjustment device 23 engages into the recess 25 so as to displace the mounting member 13 relative to the guide rail 9c. In this way, the extended end position of the guiding device 12 can be variably adjusted by the adjustment device 23.
