The present invention relates to a sliding door fitting for guiding a sliding door, and to a furniture item with a sliding door fitting of this type.
The object of a sliding door fitting for a furniture item is to guide the movement of the sliding door from a first position, in which the sliding door is open and the furniture item is accessible, toward a second position, in which the sliding door is closed and the furniture item is locked. In addition, sliding door fittings can assume the task of supporting the sliding door and in the process supporting the weight force acting on the sliding door.
DE 3731123 A1 discloses a sliding door fitting for guiding a sliding door, with an upper guide which consists of two parts which are symmetrical with respect to one another. The two parts are each produced in one piece, for example by means of drop forging.
Proceeding herefrom, the present invention is based on the object of providing a sliding door fitting for guiding a first sliding door and a second sliding door, which sliding door fitting can be used variably with low part complexity, and of specifying a furniture item with a sliding door fitting of this type.
In order to achieve the object on which the invention is based, a sliding door fitting for guiding a first sliding door and a second sliding door is proposed, comprising: a first guide element and a second guide element which can each be connected to the first sliding door, and a guide arrangement, via which the first guide element can be guided from a first closed position into a first open position, and via which the second guide element can be guided from a second closed position into a second open position.
The guide arrangement preferably has a central module and a first end module which are connected to one another at least indirectly, in particular, releasably, wherein the central module comprises a first transfer element which can be adjusted between a moved-in position and an extended position, wherein, in the moved-in position of the first transfer element, the first guide element is held in the first closed position and, in the extended position of the first transfer element, is arranged such that it can be displaced on the guide arrangement in the direction of the first open position, and the second guide element can be displaced on the first end module from the second closed position in the direction of the second open position. This measure has the advantage that the complex guide functions are integrated into the central module and the end module. The length of the sliding door fitting can be set by the fact that the central module and the end module are connected directly or indirectly to one another. In this way, a variable-length sliding door fitting is proposed, the part complexity or number of parts of which is reduced.

One embodiment of the inventive sliding door fitting will be described in the following text using the drawings of the figures, in which:
In the present case, the sliding door arrangement comprises a first sliding door 4 and a second sliding door 4′. A first guide element 5 is fastened rotatably via a first support element 6 to the first sliding door 4, and a second guide element 7 is fastened rotatably via a second support element 8 to said first sliding door. Here, the first guide element 5 is mounted rotatably about a rotational axis via a bearing on the first support element 6. The second guide element 7 is mounted rotatably about a rotational axis via a bearing on the second support element 8. A third guide element 5′ is mounted rotatably about a rotational axis via a third support element 6′ to the second sliding door 4′, and a fourth guide element 7′ is fastened rotatably about a rotational axis via a fourth support element 8′ to said second sliding door. The guide elements 5, 5′, 7, 7′ can each be configured, for example, in the form of a guide roller.
In the case of a closed first sliding door 4, the first guide element 5 is situated in a first closed position and the second guide element 7 is situated in a second closed position. The first sliding door 4 therefore closes the furniture item 2 or that part of the furniture item 2 which is assigned to the first sliding door 4. In the case of an open first sliding door 4, the first guide element 5 is situated in a first open position and the second guide element 7 is situated in a second open position. The first sliding door 4 therefore makes the furniture item 2 or that part of the furniture item 2 which is assigned to the first sliding door 4 accessible.
In the case of a closed second sliding door 4′, the third guide element 5′ is situated in a third closed position and the fourth guide element 7′ is situated in a fourth closed position. The second sliding door 4′ therefore closes the furniture item 2 or that part of the furniture item 2 which is assigned to the second sliding door 4′. In the case of an open second sliding door 4′, the third guide element 5′ is situated in a third open position and the fourth guide element 7′ is situated in a fourth open position. The second sliding door 4′ therefore makes the furniture item 2 or that part of the furniture item 2 which is assigned to the second sliding door 4′ accessible.
The guide arrangement 9 comprises a rail arrangement 10 which has a first guide rail 11 and a second guide rail 12. The first guide rail 11 is arranged between the sliding doors 4, 4′ and the second guide rail 12, with the result that the first guide rail 11 can also be called a front guide rail and the second guide rail 12 can also be called a rear guide rail.
The first guide rail 11 is configured in such a way that both the first guide element 5 which is connected to the first sliding door 4 can be guided on a first guide path and the third guide element 5′ which is connected to the second sliding door 4′ can be guided on a second guide path of the first guide rail 11.
Here, the first guide element 5 which is connected to the first sliding door 4 can follow the first guide path between the first closed position and the first open position. To this end, the first guide rail 11 has a first closure-maintaining portion 13, on which the first guide element 5 is arranged in the first closed position, a first opening-maintaining portion 15, on which the first guide element 5 is arranged in the first open position, and a first transfer portion 14 which connects the first closure-maintaining portion 13 and the first opening-maintaining portion 15 to one another.
The third guide element 5′ which is connected to the second sliding door 4′ can follow the second guide path between the third closed position and the third open position. To this end, the first guide rail 11 has a second closure-maintaining portion 13′, on which the third guide element 5′ of the second sliding door 4′ is arranged in the third closed position, a second opening-maintaining portion 15′, on which the third guide element 5′ of the second sliding door 4′ is arranged in the third open position, and a second transfer portion 14′ which connects the second closure-maintaining portion 13′ and the second opening-maintaining portion 15′ to one another.
The first guide path and the second guide path of the first guide rail 11 overlap in the region between the first closure-maintaining portion 13 and the second closure-maintaining portion 13′. It goes without saying that the overlapping regions can be of integral configuration with one another. In other words, the first guide element 5 of the first sliding door 4 and the third guide element 5′ of the second sliding door 4′ can be guided on the same rail portions of the first guide rail 11 in the region between the first closure-maintaining portion 13 and the second closure-maintaining portion 13′.
The second guide rail 12 is configured in such a way that both the second guide element 7 which is connected to the first sliding door 4 can be guided on a first guide path and the fourth guide element 7′ which is connected to the second sliding door 4′ can be guided on a second guide path of the second guide rail 12.
Here, the second guide element 7 which is connected to the first sliding door 4 can follow the first guide path of the second guide rail 12 between the second closed position and the second open position. To this end, the second guide rail 12 has a first closure-maintaining portion 19, on which the second guide element 7 is arranged in the second closed position, a first opening-maintaining portion 21, on which the second guide element 7 is arranged in the second open position, and a first transfer portion 20 which connects the first closure-maintaining portion 19 and the first opening-maintaining portion 21 to one another.
The first transfer portion 20 has a first part portion 22, a second part portion 23 and a curve portion 24. The first part portion 22 and the second part portion 23 are arranged transversely with respect to one another. The first part portion 22 and the second part portion 23 are connected to one another via the curve portion 24.
The fourth guide element 7′ which is connected to the second sliding door 4′ can follow the second guide path of the second guide rail 12 between the fourth closed position and the fourth open position. To this end, the second guide rail 12 has a second closure-maintaining portion 19′, on which the fourth guide element 7′ is arranged in the fourth closed position, a second opening-maintaining portion 21′, on which the fourth guide element 7′ is arranged in the fourth open position, and a second transfer portion 20′ which connects the second closure-maintaining portion 19′ and the second opening-maintaining portion 21′ to one another. The second transfer portion 20′ has a first part portion 22′, a second part portion 23′ and a curve portion 24′. The first part portion 22′ and the second part portion 23′ are arranged transversely with respect to one another. The first part portion 22′ and the second part portion 23′ are connected via the curve portion 24′ to one another.
As can be seen from the comparison of
The guide arrangement 9 comprises a central module 18 with a first transfer element 16 which can also be called a slide element. The first transfer element 16 can be adjusted between a moved-in position, as shown in
In the extended position of the first transfer element 16, the first guide element 5 is arranged on the guide arrangement 9 in such a way that it can be displaced from the first part portion of the first guide rail 11 in the direction of the first open position. Here, in the extended position of the first transfer element 16, the first sliding door 4 is arranged in such a way that the furniture item 2 or that part of the furniture item 2 which is assigned to the first sliding door 4 is at least partially accessible, and the first guide element 5 can be displaced on the first guide rail 11 in such a way that the sliding door 4 is completely opened. In the extended position of the first transfer element 16, the first part portion of the first guide rail 11 is arranged in such a way that a further part portion of the first guide rail 11, namely the first transfer portion 14, adjoins the first part portion, with the result that a continuous rail portion of the first guide rail 11 is formed from the two part portions. In this respect, the central module 18 comprises the first closure-maintaining portion 13 and a part of the first transfer portion 14 of the first guide rail 11.
A first part portion 17 of the second guide rail 12 is integrated into the first transfer element 16. The first closure-maintaining portion 13 and the first part portion 17 of the second guide rail 12 are arranged parallel to one another in the first transfer element 16. In the extended position of the first transfer element 16, the first part portion 17 of the second guide rail 12 is arranged in such a way that two further part portions of the second guide rail 12 are connected to one another via the first part portion 17 of the second guide rail 12, with the result that a continuous rail portion of the second guide rail 12 is formed from the three part portions. Here, a continuous rail portion is to be understood to mean that the guide roller can be guided on the rail portion, wherein possible joints are harmless. In the extended position of the first transfer element 16, the second guide element 7 can be displaced from the second closed position via the first part portion 17 of the second guide rail 12 toward the second open position.
The central module 18 has a damper unit (not shown) for damping the movement of the first transfer element 16.
As shown in
The central module 18 has a second transfer element 16′ which can be adjusted between a moved-in position and an extended position. In the moved-in position of the second transfer element 16′, the third guide element 5′ which is connected to the second sliding door 4′ is arranged in the third closed position and, in the extended position of the second transfer element 16′, can be displaced on the guide arrangement 9 in the direction of a third open position. In the present case, the central module 18 is of mirror-symmetrical configuration with regard to an axis of symmetry E_sym_9. Therefore, the second transfer element 16′ is also of mirror-inverted configuration with respect to the first transfer element 16. Identical elements are therefore labeled with identical reference signs together with an apostrophe. For the identical elements, what was said above in the context of the first transfer element 16 applies analogously to the second transfer element 16′.
A second part portion of the first guide rail 11, namely the second closure-maintaining portion 13′, is integrated into the second transfer element 16′. In the moved-in position of the second transfer element 16′, the third guide element 5′ of the second sliding door 4′ is arranged in the third closed position. In the moved-in position of the second transfer element 16′, the third guide element 5′ is held on the second closure-maintaining portion 13′ of the first guide rail 11 in the third closed position, with the result that a displacement of the third guide element 5′ in the direction of the third open position is blocked. In the moved-in position of the second transfer element 16′, the second sliding door 4′ is arranged in such a way that the furniture item 2 or that part of the furniture item 2 which is assigned to the second sliding door 4′ is closed.
In the extended position of the second transfer element 16′, the third guide element 5′ of the second sliding door 4′ is arranged on the guide arrangement 9 in such a way that it can be displaced from the second part portion of the first guide rail 11 in the direction of the second open position. Here, in the extended position of the second transfer element 16′, the second sliding door 4′ is arranged in such a way that the furniture item 2 or that part of the furniture item 2 which is assigned to the second sliding door 4′ is at least partially accessible, and the third guide element 5′ can be displaced on the first guide rail 11 in such a way that the second sliding door 4′ is completely opened. In the extended position of the second transfer element 16′, the second part portion of the first guide rail 11 is arranged in such a way that a further part portion of the first guide rail 11, namely the second transfer portion 14′, adjoins the second part portion, with the result that a continuous rail portion of the first guide rail 11 is formed by the two part portions. In this respect, the central module 18 comprises the second closure-maintaining portion 13′ and a part of the second transfer portion 14′ of the first guide rail 11.
A second part portion 17′ of the second guide rail 12 is integrated into the second transfer element 16′. The second closure-maintaining portion 13′ and the second part portion 17′ of the second guide rail 12 are arranged parallel to one another in the second transfer element 16′. In the extended position of the second transfer element 16′, the second part portion 17′ of the second guide rail 12 is arranged in such a way that two further part portions of the second guide rail 12 are connected to one another via the second part portion 17′ of the second guide rail 12, with the result that a continuous rail portion of the second guide rail 12 is formed from the three part portions. In the extended position of the second transfer element 16′, the fourth guide element 7′ of the second sliding door 4′ can be displaced from the fourth closed position via the second part portion 17′ of the second guide rail 12 toward the fourth open position.
The central module 18 has a damper unit (not shown) for damping the movement of the second transfer element 16′.
As shown in
The guide arrangement 9 comprises a first end module 25 and a second end module 25′ which each delimit the rail arrangement 10 on the end side.
The first end module 25 comprises the first closure-maintaining portion 19 and a part of the first transfer portion 20 of the second guide rail 12. The first end module 25 comprises, in particular, the first part portion 22 and the curve portion 24 of the first transfer portion 20 of the second guide rail 12. The first end module 25 therefore has the function of bridging a spacing transversely with respect to the longitudinal extent of the sliding door fitting 1 between the second closed position and the second open position. In addition, the first end module 25 comprises the second opening-maintaining portion 15′ and a part of the second transfer portion 14′ of the first guide rail 11.
The first end module 25 comprises a damper arrangement 27 which is configured to damp the movement of the third guide element 5′ of the second sliding door 4′ in the direction of the third open position at least in a last part portion of the movement. When the third guide element 5′ of the second sliding door 4′ comes into contact with the damper arrangement 27, the damper arrangement 27 pulls the third guide element 5′ of the second sliding door 4′ in the direction of the third open position. The first end module 25 therefore has the function of damping the movement of the second sliding door 4′ and/or the third guide element 5′ in the direction of the third open position and of pulling the second sliding door 4′ and/or the third guide element 5′ into the third open position.
The second end module 25′ comprises the first opening-maintaining portion 15 and a part of the first transfer portion 14 of the first guide rail 11. In addition, the second end module 25′ comprises the second closure-maintaining portion 19′ and a part of the second transfer portion 20′ of the second guide rail 12. The second end module 25′ comprises, in particular, the first part portion 22′ and the curve portion 24′ of the second transfer portion 20′ of the second guide rail 12. The second end module 25′ therefore has the function of bridging a spacing transversely with respect to the longitudinal extent of the sliding door fitting 1 between the fourth closed position and the fourth open position.
The second end module 25′ comprises a damper arrangement 27′ which is configured to damp the movement of the first guide element 5 of the first sliding door 4 in the direction of the first open position at least in a last part portion of the movement. When the first guide element 5 of the first sliding door 4 comes into contact with the damper arrangement 27′, the damper arrangement 27′ pulls the first guide element 5 of the first sliding door 4 in the direction of the first open position. The second end module 25′ therefore has the function of damping the movement of the first sliding door 4 and/or the first guide element 5 in the direction of the first open position and of pulling the first sliding door 4 and/or the first guide element 5 into the open position.
The first end module 25 is connected via a first intermediate module 26 to the central module 18. Here, the first intermediate module 26 is connected on one side releasably to the central module 18 and on the opposite side to the first end module 25. The first intermediate module 26 comprises a part of the second transfer portion 14′ of the first guide rail 11 and the second part portion 23 of the first transfer portion 20 of the second guide rail 12. The first guide rail 11 and the second guide rail 12 are arranged parallel to one another in the first intermediate module 26.
The second end module 25′ is connected via a second intermediate module 26′ to the central module 18. Here, the second intermediate module 26′ is connected on one side releasably to the central module 18 and on the opposite side to the second end module 25′. The second intermediate module 26′ comprises a part of the first transfer portion 14 of the first guide rail 11 and the second part portion 23′ of the second transfer portion 20′ of the second guide rail 12. The first guide rail 11 and the second guide rail 12 are arranged parallel to one another in the second intermediate module 26′.
The length of the first intermediate module 26 and the second intermediate module 26 can each be selected in accordance with the length of the furniture item 2. The length of the sliding door fitting 1 can therefore be varied via the at least indirect connection, in particular, by way of the selection of the intermediate modules 26, 26′. It is also conceivable here, in particular, that the intermediate modules 26, 26′ are dispensed with and the central module 18 is connected directly to the end modules 25, 25′.
