[0001] Sliding door fitting for a sliding door and a piece of furniture with such a sliding door fitting
[0002] Description
[0003] The present invention relates to a sliding door fitting for a sliding door and a piece of furniture with such a sliding door fitting.
[0004] A sliding door fitting for a piece of furniture is designed to guide the movement of the sliding door from a first position, where the sliding door is open and the furniture is accessible, to a second position, where the sliding door is closed and the furniture is locked. Sliding door fittings can also support the sliding door, thereby supporting the weight acting on it.
[0005] DE 37 09 309 A1 discloses a sliding door fitting system for at least two sliding doors. These are arranged side by side in the closed position on the same central plane, and in the sliding position on two sliding planes in front of and behind the central plane. Two upper guide rails running parallel to one another, each with a track for a roller, are coupled to one another in such a way that pushing or pulling on a sliding door perpendicular to the central plane moves the two guide rails away from or toward each other.
[0006] Based on this, the present invention is based on the object of proposing a sliding door fitting for a sliding door arrangement which enables easy opening and closing of the sliding door arrangement.To achieve the object, a sliding door fitting for a sliding door arrangement is proposed, comprising: a guide element which can be connected to the sliding door, a rail arrangement with a rail on which the guide element can be guided along a rail axis, and with a carriage element which can be moved reversibly from an extended position into a retracted position along a movement axis arranged transversely to the rail axis, wherein the guide element can be moved reversibly from an extended position into a retracted position by the carriage element, wherein the rail arrangement has a gear which converts a translational movement of the guide element relative to the carriage element in a direction parallel to the rail axis into a translational movement of the carriage element in the direction of the movement axis.
[0007] The sliding door fitting according to the invention has the advantage that the kinetic energy of the guide element can be used in a direction parallel to the rail axis to move the carriage element from an extended position to a retracted position. This allows the sliding door to be closed particularly easily and smoothly by the user.
[0008] In one possible embodiment, the carriage element can comprise a first section of the rail. In the retracted position of the carriage element, the guide element can be held on the first section of the rail in the retracted position.
[0009] In the extended position of the carriage element, the guide element can be positioned on the first section of the rail in the extended position. In the extended position of the carriage element, the first section of the rail can form a continuous rail section with a second section of the rail, so that the guide element can be guided from the extended position from the first section of the rail to the second section of the rail.
[0010] In one possible embodiment, the gear mechanism can comprise a sliding element connected to the carriage element. The sliding element can be guided in a guide groove of the rail arrangement. The sliding element can be connected to the carriage element so that it can be displaced between a receiving position and a holding position parallel to the rail axis. The sliding element is arranged in the receiving position when the carriage element is in the extended position and in the holding position when the carriage element is in the retracted position.
[0011] In one possible embodiment, the sliding door fitting can comprise an actuating element that can be at least indirectly connected to the guide element. The actuating element can be designed as a bolt or a pin. When the guide element is moved from the extended position to the retracted position, the actuating element can move the sliding element on the carriage element from the receiving position to the holding position, and vice versa.
[0012] In one possible embodiment, the sliding element can be pivotally mounted on the carriage element about a pivot axis, wherein the pivot axis is arranged transversely to the rail axis. The sliding element can comprise a recess designed to receive the actuating element in the receiving position and to couple it to the sliding element in the holding position. In the receiving position, the sliding element can be pivoted about the pivot axis such that the actuating element can be inserted into the recess in the direction of the rail axis. In the holding position, the sliding element can be pivoted about the pivot axis such that the actuating element is coupled to the sliding element.
[0013] In another possible embodiment, the sliding element can have a first guide pin and a second guide pin, each arranged in a guide recess of the carriage element. The first guide pin and the second guide pin can each have a longitudinal axis arranged transversely to the rail axis.
[0014] The guide recess can have a first section that extends parallel to the rail axis. The guide recess can also have a second section that extends transversely to a plane defined by the rail axis and the movement axis. The first guide pin can be arranged in the first section of the guide recess and the second guide pin can be arranged in the second section of the guide recess when the sliding element is arranged in the receiving position. The first guide pin and the second guide pin can each be arranged in the first section of the guide recess when the sliding element is arranged in the holding position.
[0015] In one possible embodiment, the sliding element can comprise a rotatably mounted sliding block that is guided in the guide groove of the rail arrangement. The guide groove of the rail arrangement can comprise a first subsection that extends at least substantially in the direction of the rail axis. The guide groove of the rail arrangement can also comprise a second subsection that extends at least substantially in the direction of the movement axis. The first subsection and the second subsection can be connected to one another via a curved section.
[0016] The sliding element can be guided by the first section of the guide groove when the sliding element is arranged in the receiving position. The sliding element can be guided by the second section of the guide groove when the sliding element is arranged in the holding position.
[0017] An embodiment of the sliding door fitting according to the invention for a sliding door arrangement is explained below with reference to the figures.

[0030] Figure 13 is a perspective view of the central module of the sliding door fitting according to Figure 1, without the first slide element,
[0031] Figure 14 is a perspective sectional view of the central module of the sliding door fitting according to Figure 1, wherein the movement axis of the slide element lies in the sectional plane and the slide element is arranged in the retracted position, and
[0032] Figure 15 is a perspective sectional view of the central module of the sliding door fitting according to Figure 1 on the piece of furniture, wherein the movement axis of the slide element lies in the sectional plane and the slide element is arranged in an intermediate position between the retracted position and the extended position.
[0033] Figures 1 to 15, which are described together below, show a sliding door fitting 1 for a piece of furniture 2. In this case, the sliding door fitting 1 is firmly connected to a top panel of a body 3 of the piece of furniture 2. The sliding door fitting 1 has a guide assembly 9 designed to guide and / or support a sliding door assembly.
[0034] The sliding door arrangement in the present case comprises a first sliding door 4 and a second sliding door 4'. A first guide element 5 is rotatably attached to the first sliding door 4 via a first support element 6, and a second guide element 7 is rotatably attached to the first sliding door 4 via a first support element 6, and a second guide element 7 is rotatably attached to the first support element 6 via a bearing. The second guide element 7 is rotatably attached to the second support element 8 via a bearing. A third guide element 5' is rotatably attached to the second sliding door 4' via a third support element 6' about a rotation axis, and a fourth guide element 7' is rotatably attached to the second sliding door 4' via a fourth support element 8' about a rotation axis. The guide elements 5, 5', 7, 7' can each be designed, for example, in the form of a guide roller.
[0035] When the first sliding door 4 is closed, the first guide element 5 is in a first closed position and the second guide element 7 is in a second closed position. The first sliding door 4 thus closes the piece of furniture 2 or the part of the furniture 2 assigned to the first sliding door 4. When the first sliding door 4 is open, the first guide element 5 is in a first open position and the second guide element 7 is in a second open position. The first sliding door 4 thus makes the piece of furniture 2 or the part of the furniture 2 assigned to the first sliding door 4 accessible.
[0036] When the second sliding door 4' is closed, the third guide element 5' is in a third closed position and the fourth guide element 7' is in a fourth closed position. The second sliding door 4' thus closes the piece of furniture 2 or the part of the furniture 2 assigned to the second sliding door 4'. When the second sliding door 4' is open, the third guide element 5' is in a third open position and the fourth guide element 7' is in a fourth open position. The second sliding door 4' thus makes the piece of furniture 2 or the part of the furniture 2 assigned to the second sliding door 4' accessible.
[0037] The guide assembly 9 comprises a rail assembly 10 having 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, so that the first guide rail 11 can also be referred to as the front guide rail and the second guide rail 12 as the rear guide rail. The first guide rail 11 extends along a rail axis SchA. In this case, the rail axis SchA is linear.
[0038] The first guide rail 11 is designed such that both the first guide element 5 connected to the first sliding door 4 can be guided along a first guide path and the third guide element 5' connected to the second sliding door 4' can be guided along a second guide path of the first guide rail 11. The first guide element 5 connected to the first sliding door 4 can follow the first guide path between the first closed position and the first open position. For this purpose, the first guide rail 11 has a first closed holding section 13 on which the first guide element 5 is arranged in the first closed position, a first open holding section 15 on which the first guide element 5 is arranged in the first open position, and a first transfer section 14 which connects the first closed holding section 13 and the first open holding section 15 to one another.
[0039] The third guide element 5' connected to the second sliding door 4' can follow the second guide path between the third closed position and the third open position. For this purpose, the first guide rail 11 has a second closed holding section 13' on which the third guide element 5' of the second sliding door 4' is arranged in the third closed position, a second open holding section 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 section 14' that connects the second closed holding section 13' and the second open holding section 15'.
[0040] The first guide path and the second guide path of the first guide rail 11 overlap in the region between the first locking retaining section 13 and the second locking retaining section 13'. It is understood that the overlapping regions can be configured integrally 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 sections of the first guide rail 11 in the region between the first locking retaining section 13 and the second locking retaining section 13'.
[0041] The second guide rail 12 is designed such that the second guide element 7 connected to the first sliding door 4 can be guided on a first guide path of the second guide rail 12 and the fourth guide element 7' connected to the second sliding door 4' can be guided on a second guide path of the second guide rail 12. As can be seen from a comparison of Figures 4 and 7, the first guide path and the second guide path of the second guide rail 12 partially overlap. It is understood that the overlapping regions can be designed integrally with one another. In other words, the second guide element 7 of the first sliding door 4 and the fourth guide element 7' of the second sliding door 4' can be guided on the same rail sections of the second guide rail 12 in the overlapping region.
[0042] The rail arrangement 10 comprises a central module 18 with a first transfer arrangement 16, which has a first carriage element 22. The first carriage element 22 is adjustable between a retracted position, as shown, for example, in Figures 1 and 12, and an extended position, as shown, for example, in Figures 9 and 10, along a movement axis B_22. For this purpose, the carriage element 22 is guided on a linear guide 43. However, it is also conceivable in principle for the movement axis B_22 of the carriage element 22 to have a shape deviating from straight. The movement axis B_22 of the carriage element 22 can therefore also be referred to as a movement track.
[0043] A first subsection of the first guide rail 11, namely the first closing holding section 13, is integrated into the first carriage element 22. The first guide element 5 is arranged in the first closed position in the retracted position of the first carriage element 22. In this respect, the first closed position can also be referred to as the first retracted position. The first guide element 5 is held in the first closed position in the retracted position of the first carriage element 22 on the first closing holding section 13 of the first guide rail 11. The first sliding door 4 is arranged in the retracted position of the first carriage element 22 such that the piece of furniture 2, or the part of the piece of furniture 2 assigned to the first sliding door 4, is closed.
[0044] In the extended position of the first carriage element 22, the first guide element 5 is arranged in a first extended position on the rail arrangement 9, so that it can be displaced from the first partial section 13 of the first guide rail 11 toward the first open position. The first guide element 5 is thus arranged between the first retracted position and the first extended position on the first carriage element 22.
[0045] The first sliding door 4 is arranged in the extended position of the first carriage element 22 such that the piece of furniture 2 or the part of the piece of furniture 2 which is assigned to the first sliding door 4 is at least partially accessible and the first guide element 5 can be moved on the first guide rail 11 such that the sliding door 4 is completely opened.
[0046] In the extended position of the first carriage element 22, the first partial section 13 of the first guide rail 11 is arranged such that another partial section of the first guide rail 11, namely the first transfer section 14, adjoins the first partial section 13, so that a continuous rail section of the first guide rail 11 is formed by the two partial sections. In this respect, the central module 18 comprises the first closing holding section 13 and a part of the first transfer section 14 of the first guide rail 11.
[0047] The rail arrangement 10 has a gear 34 that converts a translational movement of the first guide element 5 relative to the first carriage element 22 in a direction parallel to the rail axis SchA into a translational movement of the first carriage element 22 in the direction of the movement axis B_22. During the resulting movement of the first carriage element 22 in the direction of the movement axis B_22, the first guide element 5 is arranged on the first carriage element 22 and, at least in sections, performs a movement with a movement component parallel to the rail axis SchA and with a movement component transverse to the rail axis SchA.
[0048] The gear 34 comprises a sliding element 35 guided in a guide groove 30 of the rail assembly 10. The sliding element 35 is slidably connected to the carriage element 22. Specifically, the sliding element 35 is slidably connected to the carriage element 22 between a receiving position and a holding position parallel to the rail axis SchA. The sliding element 35 is arranged in the receiving position when the carriage element 22 is in the extended position. The sliding element 35 is arranged in the holding position when the carriage element 22 is in the retracted position.
[0049] The sliding element 35 has a sliding block 36 and a receiving section 38. The receiving section 38 is arranged in an opening 23 of the carriage element 22. The opening 23 extends parallel to the rail axis SchA in the carriage element 22. The receiving section 38 has a first guide pin 40 and a second guide pin 41 on a side facing the first sliding door 4. The first guide pin 40 and the second guide pin 41 are arranged spaced from one another in a direction parallel to the rail axis SchA. The longitudinal axis of the first guide pin 40 and the longitudinal axis of the second guide pin 41 are each arranged perpendicular to the rail axis SchA and parallel to one another.
[0050] On a side facing away from the first sliding door 4, the receiving section 38 has a third guide pin 40' and a fourth guide pin 41'. The third guide pin 40' and the fourth guide pin 41' are arranged at a distance from one another in a direction parallel to the rail axis SchA. The longitudinal axis of the third guide pin 40' and the longitudinal axis of the fourth guide pin 41' are each perpendicular to the rail axis SchA and parallel to one another. The longitudinal axis of the first guide pin 40 and the longitudinal axis of the third guide pin 40' are identical. The longitudinal axis of the second guide pin 41 and the longitudinal axis of the fourth guide pin 41' are arranged parallel and, in particular, identical. The third guide pin 40' and the fourth guide pin 41' are concealed by the remaining structure in the figures.
[0051] The first guide pin 40 and the second guide pin 41 each engage in a first guide recess 24 of the carriage element 22. The first guide recess 24 has a first section 25 extending parallel to the rail axis SchA and a second section 26 extending transversely to a plane defined by the rail axis SchA and the movement axis B_22. It will be understood by those skilled in the art that the second section 26 extends transversely to any plane defined by the direction vectors of the rail axis SchA and the movement axis B_22.
[0052] The first guide pin 40 and the second guide pin 41 are each arranged in the first partial section 25 of the first guide recess 24 when the sliding element 35 is arranged in the holding position.
[0053] The first guide pin 40 is arranged in the first section 25 of the first guide recess 24 and the second guide pin 41 is arranged in the second section 26 of the first guide recess 24 when the sliding element 35 is arranged in the receiving position.
[0054] The third guide pin 40' and the fourth guide pin 4T each engage in a second guide recess 27 of the carriage element 22. The second guide recess 27 has a first section 28 extending parallel to the rail axis SchA and a second section 29 extending transversely to a plane defined by the direction vectors of the rail axis SchA and the movement axis B_22. It will be understood by those skilled in the art that the second section 29 extends transversely to any plane defined by the direction vectors of the rail axis SchA and the movement axis B_22.
[0055] The second guide recess 27 is arranged at a distance from the first guide recess 24 in a direction perpendicular to the rail axis SchA. In other words, the second guide recess 27 is arranged parallel to the movement axis B_22 at a distance from the first guide recess 24. The second guide recess 27 and the first guide recess 24 are arranged separated from one another by the opening 23. The first guide recess 24 and the second guide recess 27 have an identical course in a direction parallel to the rail axis SchA and are arranged so as to overlap one another along the rail axis SchA. In this respect, the second guide recess 27 and the first guide recess 24 can be regarded together as a further opening in the carriage element 22, which is intersected perpendicularly by the opening 23.The first guide recess 24 and the second guide recess 27 or the further opening can thus be introduced into the slide element 22, for example, by means of a finger milling cutter.
[0056] The third guide pin 40' and the fourth guide pin 41' are each arranged in the first section 28 of the second guide recess 27 when the sliding element 35 is arranged in the holding position. The third guide pin 40' is arranged in the first section 28 of the second guide recess 27, and the fourth guide pin 41' is arranged in the second section 29 of the second guide recess 27 when the sliding element 35 is arranged in the receiving position.
[0057] When the sliding element 35 is transferred from the holding position to the receiving position, the second guide pin 41 follows the second partial section 26 of the first guide recess 24 and the fourth guide pin 4T follows the second partial section 29 of the second guide recess 27 transversely to the plane defined by the rail axis SchA and the movement axis B_22, while the first guide pin 40 is arranged in the first partial section 25 of the first guide recess 24 and the third guide pin 40' is arranged in the first partial section 28 of the second guide recess 27. Thus, when the sliding element 35 is transferred from the holding position to the receiving position, the sliding element is pivoted about a pivot axis S. The pivot axis S corresponds to the longitudinal axis of the first guide pin 40 or the third guide pin 40', respectively. The pivot axis S is thus arranged displaceably on the carriage element 22.
[0058] The receiving section 38 of the sliding element 35 has a recess 39. The recess 39 is essentially U-shaped, so that the receiving section 38 is designed similarly to an open-end wrench. In the receiving position of the sliding element 35, the recess 39 opens in a direction parallel to the rail axis SchA. The sliding door fitting 1 comprises an actuating element 42 that can be connected at least indirectly to the first guide element 5. In the present case, the actuating element 42 is fixedly connected to the first support element 6, so that an indirect connection is established between the actuating element 42 and the first guide element 5.
[0059] In the receiving position of the sliding element 35, the recess 39 opens in a direction parallel to the rail axis SchA. The actuating element 42 can enter the recess 39 of the receiving section 38 when the first guide element 5 is guided over the transfer section 14 of the first rail 11 in the direction of the closed holding section 13. The actuating element 42 thus couples to the sliding element 35 or to the first carriage element 22 in the extended position.
[0060] Subsequently, the actuating element 42 comes into contact with the receiving section 38 and thus displaces the sliding element 35 in a direction parallel to the rail axis SchA.
[0061] The force application point of the actuating element 42 on the receiving section 38 has a lever arm relative to the pivot axis S, so that the sliding element 35 is subjected to a torque, causing the sliding element 35 to pivot about the pivot axis S from the receiving position into the holding position. In this case, the second guide pin 41 is transferred from the second subsection 26 of the first guide recess 24 into the first subsection 25 of the first guide recess 24. The third guide pin 4T is transferred from the second subsection 29 of the second guide recess 27 into the first subsection 28 of the second guide recess 27.
[0062] Thus, the sliding element 35 is displaced by the actuating element 42 from the receiving position to the holding position in a direction parallel to the rail axis SchA and pivoted about the pivot axis S. In the holding position, the sliding element 35 is arranged such that the recess 39 opens in a direction transverse to the rail axis SchA. In other words, in the holding position, the actuating element 42 is held in a direction parallel to the rail axis SchA. Due to the fixed connection between the actuating element 42 and the first guide element 4, the first guide element 5 is also held in a direction parallel to the rail axis SchA.
[0063] The sliding block 36 is rotatably mounted relative to the receiving section 38 via a bearing 37. In particular, the bearing can be a 360° ball joint, a ball bearing, or a plain bearing. It is particularly conceivable for the sliding block to form the outer ring of the bearing. The sliding block 36 is designed as a sliding roller. The sliding block 36 is guided in a guide groove 30 of the rail assembly 10. In this case, the guide groove 30 is integrated into the rail assembly 10 or into the central module 18.
[0064] The guide groove 30 has a first subsection 31 that extends at least substantially parallel to the rail axis SchA. "At least substantially parallel" should be understood to mean that a vector coordinate of the extension direction of the first subsection 31 in a direction parallel to the rail axis SchA is greater in magnitude than a vector coordinate of the extension direction of the first subsection 31 in a direction transverse to the rail axis SchA.
[0065] The guide groove 30 has a second subsection 32 that extends at least substantially parallel to the movement axis B_22. "At least substantially parallel" should be understood to mean that a vector coordinate of the extension direction of the second subsection 32 in a direction parallel to the movement axis B_22 is greater in magnitude than a vector coordinate of the extension direction of the second subsection 32 in a direction transverse to the movement axis B_22. The first subsection 31 and the second subsection 32 are connected to one another via a curved section 33.
[0066] The sliding block 36 is arranged in the first section 31 when the sliding element 35 is in the receiving position. The sliding block 36 is arranged in the second section 32 when the sliding element 35 is in the holding position.
[0067] By the above-described displacement of the sliding element 35 parallel to the rail axis SchA on the first carriage element 22 by the actuating element 42, the sliding block 36 is transferred from the first partial section 31 of the guide groove 30 into the curved section 33. The sliding block 36 then comes into contact with a wall of the curved section 34. The resulting contact force increasingly displaces the sliding block 36 in a direction parallel to the movement axis B_22 of the first carriage element 22. The contact force is transmitted from the sliding element 35 to the first carriage element 22 and displaces the first carriage element 22 in the direction of the movement axis B_22.
[0068] After the sliding block 26 enters the second section 32 of the guide groove 30, the sliding element 25 is displaced parallel to the rail axis SchA on the first slide element 22 by the actuating element 42 in an analogous manner by the sliding element 25 in the direction of the movement axis B_22.
[0069] The guide groove 30 has a first groove depth in the first section 31 and a second groove depth in the second section 32. The first groove depth is greater than the second groove depth, with the groove bottom of the guide groove 30 of the first section 31 and the groove bottom of the second section 32 being connected to each other via a ramp section of the groove bottom. The ramp section is arranged in the region of the curved section.
[0070] The guide groove 30 is delimited in the region of the first subsection 31 by a first groove wall section 44 and a second groove wall section 45. If the sliding element 35 is in the receiving position, the first groove wall section 44 blocks a forced movement of the carriage element 22 along the movement axis B_22 in the direction of the retracted position, caused by an external force acting on the carriage element 22. In this case, the sliding block 36 comes into contact with the first groove wall section 44. Such an external force could, for example, be applied to the carriage element 22 by the operator of the sliding door. Analogously, the second groove wall section 45 blocks a forced movement of the carriage element 22 along the movement axis B_22 beyond the extended position when the sliding element 35 is in the receiving position and an external force acts on the carriage element 22.Here, the sliding block 36 comes into contact with the second groove wall section 45.
[0071] The central module 18 has a second transfer arrangement 16', which includes a second carriage element 22' that is adjustable between a retracted position and an extended position. The third guide element 5' connected to the second sliding door 4' is arranged in the third closed position when the second carriage element 22' is retracted and is displaceable on the rail arrangement 10 toward a third open position when the second carriage element 22' is extended. The central module 18 is designed to be mirror-symmetrical with respect to an axis of symmetry E_sym_9. Thus, the second carriage element 22' is also designed to be a mirror image of the first carriage element 22. Identical elements are therefore identified by the same reference numerals together with a prime. For identical elements, what was previously stated in the context of the first carriage element 22 applies analogously to the second carriage element 22'.
