Abstract
Description
[0001] The present invention relates to a sliding door fitting for guiding a sliding door according to the preamble of claim 1 and a piece of furniture with such a sliding door fitting.
[0002] Such a sliding door fitting has become known, for example, through WO 2018 / 065871 A1.
[0003] A sliding door fitting for a piece of furniture has the task of guiding the movement of the sliding door from a first position, in which the sliding door is open and the furniture is accessible, to a second position, in which the sliding door is closed and the furniture is locked. Additionally, sliding door fittings can support the sliding door and bear the weight force acting upon it.
[0004] In the aforementioned WO 2018 / 065871 A1, a part of a guide element, which is connected to the sliding door, moves in a groove inside a transfer element, which lifts a roller from the guide rail and allows the roller to move on or away from the guide rail without causing friction or impacts.
[0005] From DE 3731123 A1, a sliding door fitting for guiding a sliding door of a cabinet is known, with an upper guide consisting of two mutually symmetrical parts and comprising a front and a rear rail. Spring-loaded stop elements are arranged at one end of the rear rail facing the side of the cabinet.
[0006] Starting from this, the present invention aims to provide a sliding door fitting for guiding a sliding door, which has a space-efficient design, as well as a piece of furniture with such a sliding door fitting.
[0007] To solve the problem underlying the invention, a sliding door fitting for guiding a first sliding door with the features of claim 1 is proposed.
[0008] In this inventive sliding door fitting, the damping force of the damper unit in the central section is initially transferred to the first guide element. Subsequently, the damping force can be transferred from the first guide element to the second guide element. This transfer can occur via the sliding door itself or via a separate connecting element. The force flow thus proceeds from the first damper unit, through the first guide element, to the second guide element. The first damper unit is therefore also designed to dampen the movement of the second guide element from the second open position to the second closed position.
[0009] In the inventive sliding door fitting, the guide arrangement comprises a central module and a first end module. The central module can form the middle section of the guide arrangement, and the first end module can form the first end section of the guide arrangement. The central module includes the first damper unit. In particular, the first damper unit can be integrated into the central module. Thus, the middle section of the guide arrangement, together with the first damper unit, can be integrated into the central module.
[0010] In the inventive sliding door fitting, the central module comprises a first transfer element that is adjustable between a retracted position and an extended position. In the retracted position of the first transfer element, the first guide element can be held in the first closed position. In the extended position of the first transfer element, the first guide element can be slidably arranged on the guide assembly in the direction of the first open position. In the extended position of the first transfer element, the second guide element can be slidably arranged on the first end module from the second closed position in the direction of the second open position. The first damper unit can be connected to the first transfer element.
[0011] The central module can comprise a housing. The first transfer element can be guided in or on the housing. The first damper unit can be at least partially integrated into the housing.
[0012] In one possible embodiment, the second guide element can be guided and / or supported by the central module in the second open position.
[0013] In one possible embodiment, the central module or the central section can be arranged at least partially in a central plane of the guide arrangement, in particular a plane of symmetry of the guide arrangement. The central plane is understood to be the plane that divides the longitudinal extent of the sliding door fitting into equal parts.
[0014] In one possible embodiment, the sliding door fitting can comprise a third guide element and a fourth guide element, each of which can be connected to a second sliding door. The guide arrangement can be configured such that the third guide element can be moved from a third closed position to a third open position, and the fourth guide element can be moved from a fourth closed position to a fourth open position. The third closed position of the third guide element can be located in the area of the central section. The fourth closed position of the fourth guide element can be located in the area of the second end section.
[0015] The guide assembly can have a second end module, which forms the second end section of the guide assembly and is connected to the central module, at least indirectly, and in particular detachably. The fourth guide element can be displaceable on the second end module from the fourth closed position towards the fourth open position.
[0016] The central module can include a second transition element that is adjustable between a retracted position and an extended position, wherein the third guide element is held in the third closed position in the retracted position of the second transition element and is slidably arranged on the guide assembly towards the third open position in the extended position of the second transition element. The second damper unit can be connected to the second transition element directly or indirectly.
[0017] In a further embodiment, a second damping unit can be provided to dampen a movement of the third guide element from the third open position to the third closed position, wherein a damping force of the second damping unit can be transferred via the third guide element to the fourth guide element.
[0018] The second transition element can be guided in or on the housing of the central module. The second damper unit can be at least partially integrated into the housing of the central module. Thus, the central module can incorporate the central section of the guide assembly together with the first damper unit and / or the second damper unit.
[0019] The first damper unit and / or the second damper unit can be designed as a hydraulic damper, a pneumatic damper or a friction damper, in particular as a telescopic damper.
[0020] In another possible embodiment, the second end module can comprise a housing that includes a track section of the guide arrangement on which the first guide element is positioned in the first open position. A first damper arrangement for damping the movement of the first guide element from the first closed position to the first open position can be integrated into the housing of the second end module. Thus, the second end section of the guide arrangement, together with the first damper arrangement, can be integrated into the second end module. A damping force from the first damper arrangement can be transmitted to the second guide element via the first guide element.
[0021] In one possible embodiment, the first end module can comprise a housing that includes a track section of the guide arrangement on which the third guide element is arranged in the third open position. A second damper arrangement can be integrated into the housing to dampen the movement of the third guide element from the third closed position to the third open position. Thus, the first end module can integrate the first end section of the guide arrangement together with the second damper arrangement. A damping force from the second damper arrangement can be transmitted via the third guide element to the fourth guide element.
[0022] The first damper arrangement and / or the second damper arrangement can be designed as a retraction damper unit.
[0023] The problem underlying the invention is further solved by a piece of furniture comprising: a body and a first sliding door and / or a second sliding door, and a sliding door fitting of a previously described type, which is connected to the body, wherein the first guide element and the second guide element are each connected to the first sliding door and / or the third guide element and the fourth guide element are each connected to the second sliding door.
[0024] The first sliding door closes the furniture when the first guide element is in the first closed position and the second guide element is in a second closed position, and the first sliding door makes the furniture accessible when the first guide element is in the first open position and the second guide element is in a second open position.
[0025] The second sliding door closes the furniture when the third guide element is in the third closed position and the fourth guide element is in the third closed position, and the second sliding door makes the furniture accessible when the third guide element is in the third open position and the fourth guide element is in a fourth open position.
[0026] One embodiment of the inventive sliding door fitting is described below with reference to the figures. Herein, it shows Figure 1 shows a top view of a piece of furniture with a first sliding door, a second sliding door and a sliding door fitting according to the invention, wherein both sliding doors close the furniture; Figure 2 shows the view from Figure 1 , wherein the first sliding door is arranged in a first partially open position; Figure 3 the view from Figure 1, wherein the first sliding door is arranged in a second partially open position; Figure 4 the view from Figure 1 , wherein the first sliding door is arranged in a fully open position; Figure 5 the view from Figure 1 , wherein the second sliding door is arranged in a first partially open position; Figure 6 the view from Figure 1 , wherein the second sliding door is arranged in a second partially open position; Figure 7 the view from Figure 1 , wherein the second sliding door is arranged in a fully open position; Figure 8 shows a detailed view of the central module of the sliding door fitting made of Figure 1 without cover, Figure 9 shows a detailed view of the first end module of the sliding door fitting made of Figure 1 Figure 10 shows a detailed view of the second end module of the sliding door fitting. Figure 1Figure 11 shows a perspective view of a section through the central module along a longitudinal axis of the first damper unit, wherein the first transition element is arranged in the retraction position; and Figure 12 shows a perspective view of a section through the central module along a longitudinal axis of the first damper unit, wherein the first transition element is arranged in the extension position.
[0027] In the Figures 1 to 12 Figure 1, which is described together below, shows a sliding door fitting 1 for a piece of furniture 2. In this case, the sliding door fitting 1 is fixedly connected to the top of a body 3 of the furniture 2. The sliding door fitting 1 has a guide arrangement 9, which is designed to guide and / or support a sliding door assembly.
[0028] The sliding door arrangement comprises a first sliding door 4 and a second sliding door 4'. A first guide element 5 is attached to the first sliding door 4 via a first support element 6, and a second guide element 7 is attached via a second support element 8. The first guide element 5 is rotatably mounted on the first support element 6 via a bearing. The second guide element 7 is rotatably mounted on the second support element 8 via a bearing. A third guide element 5' and a fourth guide element 7' are rotatably mounted on the second sliding door 4' via a third support element 6' and a fourth guide element 7' are rotatably mounted on the second sliding door 4' via a fourth support element 8'. The guide elements 5, 5', 7, and 7' can each be designed, for example, in the form of a guide roller.
[0029] 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 furniture 2, or rather the part of the furniture 2 that is associated with 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 furniture 2, or rather the part of the furniture 2 that is associated with the first sliding door 4, accessible.
[0030] 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 furniture 2, or rather, the part of the furniture 2 that is associated with 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 furniture 2, or rather, the part of the furniture 2 that is associated with the second sliding door 4', accessible.
[0031] 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, 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.
[0032] The first guide rail 11 is designed in such a way that both the first guide element 5 connected to the first sliding door 4 can be guided on a first guide path and the third guide element 5' connected to the second sliding door 4' can be guided on a second guide path of the first guide rail 11.
[0033] 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 closing holding section 13 on which the first guide element 5 is arranged in the first closed position, a first opening holding section 15 on which the first guide element 5 is arranged in the first open position, and a first transition section 14 that connects the first closing holding section 13 and the first opening holding section 15.
[0034] 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 closing hold section 13' on which the third guide element 5' of the second sliding door 4' is arranged in the third closed position, a second opening hold 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 transition section 14' that connects the second closing hold section 13' and the second opening hold section 15'.
[0035] The first guide path and the second guide path of the first guide rail 11 overlap in the area between the first closing hold section 13 and the second closing hold section 13'. It is understood that the overlapping areas can be integrally designed. 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 area between the first closing hold section 13 and the second closing hold section 13'.
[0036] The second guide rail 12 is designed such that both the second guide element 7 connected to the first sliding door 4 can be guided on a first guide path 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.
[0037] The second guide element 7, 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. For this purpose, the second guide rail 12 has a first closing hold section 19, on which the second guide element 7 is arranged in the second closed position, a first opening hold section 21, on which the second guide element 7 is arranged in the second open position, and a first transition section 20, which connects the first closing hold section 19 and the first opening hold section 21.
[0038] The first overpass section 20 has a first subsection 22, a second subsection 23, and a curved section 24. The first subsection 22 and the second subsection 23 are arranged transversely to each other. The first subsection 22 and the second subsection 23 are connected to each other via the curved section 24.
[0039] The fourth guide element 7', 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. For this purpose, the second guide rail 12 has a second closing hold section 19' on which the fourth guide element 7' is arranged in the fourth closed position, a second opening hold section 21' on which the fourth guide element 7' is arranged in the fourth open position, and a second transition section 20' that connects the second closing hold section 19' and the second opening hold section 21'. The second transition section 20' has a first subsection 22', a second subsection 23', and a curved section 24'. The first subsection 22' and the second subsection 23' are arranged transversely to each other.The first section 22' and the second section 23' are connected via the curve section 24'.
[0040] As can be seen from the comparison of the Figures 4 and 7 As can be seen, the first guide path and the second guide path of the second guide rail 12 partially overlap. It is understood that the overlapping areas can be integrally designed. 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 area.
[0041] The guide arrangement 9 comprises a central module 18 with a first transfer element 16, which can also be referred to as a slide element. The first transfer element 16 is positioned between a retraction position, as shown in Figure 1 shown, and an ejection position, as for example in Figure 8 shown, adjustable. The central module 18 has a housing 34 on which the first transfer element 16 is slidably mounted on a guide 35, which is designed in particular as a linear guide, along a movement axis L_35.
[0042] The first transfer element 16 incorporates a first subsection of the first guide rail 11, namely the first locking retaining section 13. The first guide element 5 is positioned in the first closed position when the first transfer element 16 is in its retracted position. In this position, the first guide element 5 is held on the first locking retaining section 13 of the first guide rail 11, thus preventing the first guide element 5 from moving towards the first open position. The first sliding door 4 is positioned in the retracted position of the first transfer element 16 such that the furniture 2, or the part of the furniture 2 associated with the first sliding door 4, is closed.
[0043] In the extended position of the first transfer element 16, the first guide element 5 is arranged on the guide assembly 9 such that it can be displaced from the first section of the first guide rail 11 towards the first open position. The first sliding door 4 is arranged in the extended position of the first transfer element 16 such that the furniture 2, or the part of the furniture 2 associated with 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 so that the first sliding door 4 is fully opened.In the extended position of the first transfer element 16, the first subsection of the first guide rail 11 is arranged such that a further subsection of the first guide rail 11, namely the first transfer section 14, connects to the first subsection, so that a continuous rail section of the first guide rail 11 is formed by the two subsections. In this respect, the central module 18 comprises the first locking retaining section 13 and a part of the first transfer section 14 of the first guide rail 11.
[0044] The first transition element 16 integrates a first subsection 17 of the second guide rail 12. The first locking retaining section 13 and the first subsection 17 of the second guide rail 12 are arranged parallel to each other within the first transition element 16. In the extended position of the first transition element 16, the first subsection 17 of the second guide rail 12 is arranged such that two further subsections of the second guide rail 12 are connected to each other via the first subsection 17 of the second guide rail 12, forming a continuous rail section of the second guide rail 12 from the three subsections. A continuous rail section is defined as one in which the guide roller can be guided along the rail section, and any gaps between the sections are not detrimental.In the extended position of the first transfer element 16, the second guide element 7 can be moved from the second closed position via the first section 17 of the second guide rail 12 to the second open position.
[0045] The central module 18 has a first damper unit 30 for damping the movement of the first transition element 16 from the first open position to the first closed position. The first damper unit 30 is designed as a monotube damper. However, any other damper design is also conceivable, for example, a twin-tube damper or a rotary damper. The first damper unit 30 comprises a cylinder 31 in which a piston 32 is guided. The cylinder 31 is integrated into the housing 34 of the central module 18. The cylinder 31 and the piston 32 extend along a longitudinal axis L_30 of the first damper unit 30, which is arranged parallel to the axis of movement L_35.
[0046] The piston 32 divides the cylinder 31 into two variable chambers in a known manner and extends out of the cylinder 31 with a connecting section 33.
[0047] The piston 32 is rigidly connected to the first transition element 16 via the connecting section 33. The piston 32 thus follows the movement of the first transition element 16. This movement of the piston 32 varies the respective volumes of the two chambers of the first damper unit 30, and the fluid contained therein, for example oil or air, flows via a valve arrangement from the decreasing chamber to the increasing chamber of the cylinder 31. This exerts a force on the piston 32 that opposes the movement of the first transition element 16 and dampens it.
[0048] The damping force of the first damper unit 30 is thus transmitted via the first transfer element 16 to the first guide element 5 when the latter is moved towards the first closing position. The damping force is transmitted from the first guide element 5 to the first sliding door 4 and from there to the second guide element 7.
[0049] The central module 18 has a second transfer element 16' 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 transfer element 16' is retracted, and in the extended position of the second transfer element 16', it can be moved along the guide arrangement 9 towards a third open position. The central module 18 is designed to be mirror-symmetrical with respect to an axis of symmetry E_sym_9. Therefore, the second transfer element 16' is also designed as a mirror image of the first transfer element 16. Identical elements are thus indicated with the same reference numerals together with a superscript. For identical elements, what was previously stated in the context of the first transfer element 16 applies analogously to the second transfer element 16'.
[0050] A second section of the first guide rail 11, namely the second locking section 13', is integrated into the second transfer element 16'. The third guide element 5' of the second sliding door 4' is positioned in the third closed position when the second transfer element 16' is in the retracted position. In this position, the third guide element 5' is held on the second locking section 13' of the first guide rail 11, thus preventing the third guide element 5' from moving towards the third open position. The second sliding door 4' is positioned in the retracted position of the second transfer element 16' such that the furniture 2, or the part of the furniture 2 associated with the second sliding door 4', is closed.
[0051] 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 assembly 9 such that it can be moved from the second closing retaining section 13' of the first guide rail 11 towards the second open position. The second sliding door 4' is arranged in the extended position of the second transfer element 16' such that the furniture 2, or the part of the furniture 2 associated with the second sliding door 4', is at least partially accessible, and the third guide element 5' can be moved on the first guide rail 11 so that the second sliding door 4' is fully opened.In the extended position of the second transfer element 16', the second subsection of the first guide rail 11 is arranged such that a further subsection of the first guide rail 11, namely the second transfer section 14', connects to the second subsection, so that a continuous rail section of the first guide rail 11 is formed by the two subsections. In this respect, the central module 18 comprises the second locking retaining section 13' and a part of the second transfer section 14' of the first guide rail 11.
[0052] A second subsection 17' of the second guide rail 12 is integrated into the second transfer element 16'. The second closing retaining section 13' and the second subsection 17' of the second guide rail 12 are arranged parallel to each other in the second transfer element 16'. In the extended position of the second transfer element 16', the second subsection 17' of the second guide rail 12 is arranged such that two further subsections of the second guide rail 12 are connected to each other via the second subsection 17' of the second guide rail 12, so that a continuous rail section of the second guide rail 12 is formed by the three subsections. In the extended position of the second transfer element 16', the fourth guide element 7' of the second sliding door 4' can be moved from the fourth closed position via the second subsection 17' of the second guide rail 12 to the fourth open position.
[0053] The central module 18 has a second damper unit 30' for damping the movement of the third guide element 5' from the third open position to the third closed position. The second damper unit 30' is designed analogously to the first damper unit 30. The second damper unit 30' thus comprises a cylinder in which a piston is guided. The cylinder is integrated into the housing 34 of the central module 18. The cylinder and the piston extend along a longitudinal axis of the damper unit 30', which is arranged parallel to a movement axis of the second transition element 16'. The piston divides the cylinder into two variable chambers in a known manner and extends out of the cylinder with a connecting section. The piston is connected to the second transition element 16' via the connecting section. The piston thus follows a movement of the second transition element 16'.The movement of the piston varies the respective volume of the two chambers of the cylinder, and the fluid contained therein, for example oil or air, flows via a valve arrangement from the decreasing chamber to the increasing chamber of the cylinder. This exerts a force on the piston that opposes the movement of the second transfer element 16' and dampens it.
[0054] The damping force of the second damper unit 30' is thus transferred via the second transfer element 16' to the third guide element 5' when the latter is moved towards the third closing position. The damping force is transferred from the third guide element 5' to the second sliding door 4' and from there to the fourth guide element 7'.
[0055] The guide assembly 9 comprises a first end module 25 and a second end module 25', each of which delimits the guide assembly 9 at its ends. In other words, the guide assembly 9 extends from a first end section 28, formed by the first end module 25, to a second end section 28', formed by the second end module 25'. The first end section 28 and the second end section 28' are connected via a central section 29, which is formed at least partially by the central module 18.
[0056] The first end module 25 comprises the first closing hold section 19 and part of the first transition section 20 of the second guide rail 12. Specifically, the first end module 25 comprises the first subsection 22 and the curved section 24 of the first transition section 20 of the second guide rail 12. The first end module 25 thus serves to bridge a gap transverse to the longitudinal extent of the sliding door fitting 1 between the second closed position and the second open position. The first end module 25 also comprises the second opening hold section 15' and part of the second transition section 14' of the first guide rail 11.
[0057] The first end module 25 comprises a second damper assembly 27, which is configured to dampen the movement of the third guide element 5' of the second sliding door 4' towards the third open position, at least in the final part of the movement. When the third guide element 5' of the second sliding door 4' comes into contact with the second damper assembly 27, the second damper assembly 27 retracts the third guide element 5' of the second sliding door 4' towards the third open position. The first end module 25 thus has the function of damping the movement of the second sliding door 4' and / or the third guide element 5' towards the third open position and retracting the second sliding door 4' and / or the third guide element 5' into the third open position. In this respect, the second damper assembly 27 can also be referred to as a retraction damper unit.The first end module 25 comprises a housing 36 in which the second damper arrangement 27 is received and guided.
[0058] The second end module 25' comprises the first opening-holding section 15 and part of the first transition section 14 of the first guide rail 11. The second end module 25' also comprises the second closing-holding section 19' and part of the second transition section 20' of the second guide rail 12. In particular, the second end module 25' comprises the first subsection 22' and the curved section 24' of the second transition section 20' of the second guide rail 12. The second end module 25' thus has the function of bridging a gap transverse to the longitudinal extent of the sliding door fitting 1 between the fourth closed position and the fourth open position.
[0059] The second end module 25' comprises a first damper assembly 27', which is configured to dampen the movement of the first guide element 5 of the first sliding door 4 towards the first open position, at least in the final part of the movement. When the first guide element 5 of the first sliding door 4 comes into contact with the first damper assembly 27', the first damper assembly 27' retracts the first guide element 5 of the first sliding door 4 towards the first open position. The second end module 25' thus has the function of damping the movement of the first sliding door 4 and / or the first guide element 5 towards the first open position and retracting the first sliding door 4 and / or the first guide element 5 into the open position. In this respect, the second damper assembly 27' can also be referred to as a retraction damper unit. The second end module 25' comprises a housing 36' in which the first damper assembly 27' is received and guided.
[0060] The first end module 25 is connected to the central module 18 via a first intermediate module 26. The first intermediate module 26 is detachably connected to the central module 18 on one side and to the first end module 25 on the opposite side. The first intermediate module 26 comprises part of the second transition section 14' of the first guide rail 11 and the second subsection 23 of the first transition section 20 of the second guide rail 12. The first guide rail 11 and the second guide rail 12 are arranged parallel to each other in the first intermediate module 26.
