Description

[0001] The present invention relates to a guide rail for a sliding door with a guide element, in particular for a piece of furniture, according to the preamble of claim 1.

[0002] Such a guide rail is known, for example, from EP 3 864 244 B1.

[0003] Guide rails for sliding doors serve the purpose of guiding the sliding door from an open position to a closed position. Additionally, guide rails can support the sliding door and bear the weight force acting upon it.

[0004] The aforementioned EP 3 864 244 B1 discloses a guide rail for a sliding door in which pivotable switch elements accordingly open or close a guide channel for a guide element of the sliding door.

[0005] GB 871 745 A discloses a guide rail for a sliding door in which switch elements can be pivoted into an open position and into a closed position.

[0006] US 2015 / 300068 A1 discloses a guide rail for a sliding door in which a further guide channel is provided in which a further guide element of the sliding door can be guided.

[0007] From DE 29 12 256 C2, a guide rail is known on which two sliding doors are guided, lying in a common plane when closed. The guide rail includes a central diverter over which the two sliding doors are guided and which can be pivoted so that the two sliding doors lie in parallel planes and can be guided past each other. The plane in which the sliding doors lie when open intersects the plane in which the sliding doors lie when closed. The sliding doors are guided by two guide rollers each on the guide rail and the central diverter, which engage in a groove in the sliding doors.

[0008] Starting from this premise, the present invention aims to provide a guide rail for a sliding door with a guide element that enables stable guidance of the sliding doors.

[0009] The problem underlying the present invention is solved by a guide rail for a sliding door, in particular for a piece of furniture, having the features of claim 1.

[0010] The guide rail according to the invention has the advantage that the guide element of the sliding door can be guided stably within the guide channel and can be transferred stably from the guide channel to the holder section via the switch element.

[0011] The guide rail can be designed, in particular for at least one sliding door, with at least one guide element. This guide element can be designed as a guide roller. The axis of rotation of the guide roller can be arranged parallel to the pivot axis of the switch element.

[0012] Specifically, the guide rail for at least one sliding door can be designed with two guide elements, each in the form of a guide roller. The axis of rotation of each of the two guide rollers can be arranged parallel to the pivot axis of the switch element.

[0013] In one possible embodiment of the guide rail according to the invention, the guide channel in the open position of the switch element can be divided into a first channel area and a second channel area such that the guide element cannot be transferred from the first channel area to the second channel area. In other words, the guide channel in the open position of the switch element can be divided into a first channel area and a second channel area such that the transfer of the guide element from the first channel area to the second channel area is blocked.

[0014] In another possible embodiment, the switch element can be pivoted from the open position to the closed position by the guide element. In particular, the switch element can be pivoted from the open position to the closed position when the guide element is moved from the guide channel into the holding section.

[0015] Furthermore, an embodiment is possible in which the pivot axis of the switch element is arranged obliquely to the central axis of the guide channel. In particular, the pivot axis of the switch element can be arranged obliquely and orthogonally to the central axis of the guide channel. In one possible embodiment, the pivot axis of the switch element can be arranged outside the guide channel.

[0016] In one possible embodiment of the guide rail according to the invention, the switch element can comprise a separating section which, in the open position, is arranged in the guide channel and, in the closed position, forms a section of the wall of the guide channel. The separating section can have a concave transition surface and a straight channel wall surface. In the open position, the concave transition surface can define a transition channel through which the guide element can be transferred from the guide channel into the holding section. Alternatively, or in combination with this, the straight channel wall surface can form the section of the wall of the guide channel in the closed position.

[0017] In another possible embodiment, the switch element can include an actuating section that, in the open position, is located outside the guide channel and, in the closed position, defines the stopping section. The actuating section can have a concave transition surface and a straight stopping section boundary surface. The concave transition surface of the actuating section can form an actuating contour with the concave transition surface of the separating section, which, in the open position, defines the transition channel. The straight stopping section boundary surface can define the stopping section in the closed position.

[0018] The switch element can be L-shaped. The separating section can be arranged transversely to the actuating section. In particular, a longitudinal axis of the separating section can be arranged at a right angle to the longitudinal axis of the actuating section.

[0019] In another possible embodiment, a first spring element can be provided that applies a first spring force to the switch element, causing the switch element to pivot into the open position. The first spring element can be, for example, a coil spring, torsion spring, compression spring, or tension spring.

[0020] In another possible embodiment, a second spring element can be provided which, in the open position of the switch element, is in contact with the switch element in such a way that the switch element is held in the open position by the second spring element. Alternatively or in combination, the second spring element can be in contact with the switch element in the closed position in such a way that the switch element is held in the closed position by the second spring element. The second spring element can be in contact with the switch element in such a way that a frictional or positive locking connection is established between the second spring element and the switch element.

[0021] A frictional force can act between the second spring element and the switch element, at least partially, along the pivoting path of the switch element from the closed to the open position. This frictional force can also be described as a damping force with respect to the pivoting movement of the switch element. Furthermore, in one embodiment, the spring force of the second spring element can be varied as the guide element moves from the guide channel into the holding section through the guide element.

[0022] In one possible embodiment, the second spring element can have a hook section which, in the open position of the switch element, is in contact with the switch element such that the switch element is held in the open position by the hook section. Alternatively, or in combination, the hook section can be in contact with the switch element in the closed position such that the switch element is held in the closed position by the hook section. Here, the second spring element can be designed as a spring tab with the hook section at one free end. The guide rail can encompass the first spring element and the second spring element in combination. Alternatively, it is also conceivable that the guide rail encompasses one of the first spring elements and one of the second spring elements.

[0023] In one possible embodiment of the guide rail according to the invention, the retaining section can be arranged in radial overlap with the guide channel. The arrangement of the retaining section in radial overlap with the guide channel is to be understood as meaning that the retaining section is at least partially arranged in a plane that is perpendicular to the central axis of the first guide channel.

[0024] In another possible embodiment, it can be provided that a guide element of a further sliding door can be guided in the guide channel, that a further holding section is provided, that a further switch element is provided which can be pivoted about a further pivot axis into an open position and into a closed position, wherein the pivoting from the open position to the closed position of the further switch element occurs in the opposite direction to the pivoting of the switch element, that the switch element in the open position divides the guide channel into a third channel area and a fourth channel area, wherein the third channel area is connected to the further holding section in such a way that the guide element of the further sliding door can be transferred from the third channel area into the further holding section, and that the further switch element in the closed position releases the guide channel in such a way thatthat the third channel area is connected to the fourth channel area, wherein in particular the guide element of the sliding door can be guided from the third channel area into the fourth channel area.

[0025] In another possible embodiment, the guide channel in the open position can be subdivided by the further switch element into the third channel area and the fourth channel area in such a way that the guide element of the further sliding door cannot be transferred from the third channel area to the fourth channel area.

[0026] An exemplary embodiment is explained below with reference to the figures. Here, it shows Figure 1 shows a view of the base of a piece of furniture with a guide rail according to the invention, wherein a first sliding door and a second sliding door are each shown in the closed position; Figure 2 shows the guide rail made of Figure 1, wherein a first sliding door is shown in a partially open position and a second sliding door in a closed position; Figure 3 the guide rail made of Figure 1 , where the first sliding door is shown in the open position and the second sliding door in the closed position; Figure 4 the rail center module of the guide rail made of Figure 1 , wherein a first switch element and a second switch element are each arranged in the closed position; Figure 5 the rail center module of the guide rail made of Figure 1 together with the first and second sliding doors, each in the closed position, Figure 6, the center rail module of the guide rail made of Figure 1 together with the first sliding door in a partially open position and the second sliding door in a closed position; Figure 7 the center rail module of the guide rail made of Figure 1together with the first sliding door in an intermediate position and the second sliding door in the closed position; Figure 8 a cross-section through the guide rails made of Figure 1 along the cutting plane VIII-VIII from Figure 7 , wherein the first guide roller of the first sliding door and the first retaining element of the second sliding door are arranged in the section plane, Figure 9 shows a section through the hook section of the second spring element with the switch element in the closed position; and Figure 10 shows a section through the hook section of the second spring element with the switch element in the open position.

[0027] In the Figures 1 to 10Figure 1, which is described jointly below, shows a guide rail 1 according to the invention, which is attached to a base of a piece of furniture 31. In the present case, this is the bottom of the furniture 31, although it is also conceivable that the guide rail 1 is attached to a top of the furniture 31. The guide rail 1 is configured to guide a first sliding door 2 and a second sliding door 2'. The first sliding door 2 and the second sliding door 2' can each be guided along the guide rail 1 from a closed position, in which the respective sliding door closes a part of the furniture 31 associated with the sliding door, to an open position, in which the respective sliding door releases the part of the furniture associated with the sliding door. In the fully closed position, the first sliding door 2 and the second sliding door 2' each lie in a closing plane E_S.In the fully open position, the first sliding door 2 lies in a first opening plane E_O, and the second sliding door lies in a second opening plane. In this case, the first opening plane E_O and the second opening plane lie in the same plane, without being restricted to it. The first opening plane E_O and the second opening plane are parallel to and, in this case, perpendicular to the closing plane E_S. However, it is also conceivable that the first opening plane E_O and the second opening plane are arranged perpendicular to the closing plane E_S and, in particular, enclose an acute angle.

[0028] The first sliding door 2 comprises a first guide element 3 in the form of a guide roller, which is connected to the first sliding door 2 via a first retaining element 4. The first sliding door 2 also comprises a second guide element 5, which is connected to the first sliding door 2 via a second retaining element 6. The first guide element 3 of the first sliding door 2 has a pivot axis L_D3, which is arranged parallel to and, in particular, spaced apart from the first sliding door 2. The pivot axis L_D3 of the first guide element 3 of the first sliding door 2 is also arranged parallel to and, in particular, spaced apart from the closing plane E_S. The second guide element 5 of the first sliding door 2 has a pivot axis L_D5, which is arranged parallel to and, in particular, spaced apart from the first sliding door 2. The pivot axis L_D5 of the second guide element 5 of the first sliding door 2 is also arranged parallel to and, in particular, spaced apart from the closing plane E_S.

[0029] The second sliding door 2' comprises a first guide element 3' in the form of a guide roller, which is connected to the second sliding door 2' via a first retaining element 4'. The second sliding door 2' also comprises a second guide element 5', which is connected to the second sliding door 2' via a second retaining element 6'. The first guide element 3' of the second sliding door 2' has a pivot axis L_D3', which is arranged parallel to and, in particular, spaced apart from the second sliding door 2'. The pivot axis L_D3' of the first guide element 3' of the second sliding door 2' is also arranged parallel to and, in particular, spaced apart from the closing plane E_S. The second guide element 5' of the second sliding door 2' has a pivot axis L_D5', which is arranged parallel to and, in particular, spaced apart from the second sliding door 2'.The axis of rotation L_D5' of the second guide element 5' of the second sliding door 2' is also arranged parallel and, in particular, spaced apart from the closing plane E_S.

[0030] The guide rail 1 comprises a first guide channel 7 extending along a central axis L_7. In this case, the central axis L_7 is straight, so it can also be referred to as the longitudinal axis of the first guide channel 7. However, it is also conceivable that the central axis L_7 could have a shape other than straight.

[0031] The first guide channel 7 is bounded by a first wall 32 and a second wall 33. The distance between the first wall 32 and the second wall 33 is essentially constant, at least in sections.

[0032] A first retaining section 15 is arranged radially overlapping the first guide channel 7 and is connected to the first guide channel 7 in such a way that the first guide element 3 of the first sliding door 2 can be guided from the first guide channel 7 into the first retaining section 15. The first retaining section 15 is bounded by a contact surface 16, against which the first guide element 3 of the first sliding door 2 can be brought into contact. Thus, the movement of the first guide element 3, or of the first sliding door 2, can be limited by the contact surface 16. The contact surface 16 can therefore also be referred to as a limit stop.

[0033] A second retaining section 15' is arranged radially overlapping the first guide channel 7 and is connected to the first guide channel 7 in such a way that the first guide element 3' of the second sliding door 2' can be guided from the first guide channel 7 into the second retaining section 15'. The arrangement of the respective retaining sections in radial overlap with the first guide channel 7 is to be understood as meaning that the respective retaining section is at least partially arranged in a plane that is perpendicular to the central axis L_7 of the first guide channel 7.

[0034] The first retaining section 15 is arranged radially away from the first guide channel 7 with respect to its central axis L_7. The second retaining section 15' is also arranged radially away from the first guide channel 7 with respect to its central axis L_7. In the present case, the first retaining section 15 and the second retaining section 15' are arranged radially away from the first guide channel 7 by the same amount with respect to its central axis L_7. However, it is also conceivable that the first retaining section 15 and the second retaining section 15' are arranged radially away from the first guide channel 7 by different amounts with respect to its central axis L_7.

[0035] The first stopping section 15 and the second stopping section 15' are arranged separately from each other along the central axis L_7 of the first guide channel 7. In this case, the first stopping section 15 and the second stopping section 15' are spatially separated. However, it is also conceivable that the first stopping section 15 and the second stopping section 15' are connected, merge into each other, and / or are integrally designed together.

[0036] The second holding section 15' is bounded by a contact surface 16', against which the first guide element 3' of the second sliding door 2' can be brought into contact. Thus, the movement of the first guide element 3' and the second sliding door 2' can be limited by the contact surface 16'. The contact surface 16' can therefore also be referred to as a limit stop.

[0037] The first guide channel 7 is connected to the first holding section 15 via a first overpass section 17. The first overpass section 17 extends through the second wall 33 of the guide channel 7. The second wall 33 is therefore interrupted in the area of ​​the first overpass section 17. In other words, the second wall 33 has a first opening in the area of ​​the first overpass section 17.

[0038] The first guide channel 7 is connected to the second holding section 15' via a second crossover section 17'. The second crossover section 17' extends through the second wall 33 of the guide channel 7. The second wall 33 is thus interrupted in the area of ​​the second crossover section 17'. In other words, the second wall 33 has a second opening in the area of ​​the second crossover section 17'. In this case, the second opening is arranged opposite the first opening in the direction of the central axis L_7. However, it is also conceivable that the first opening and the second opening merge into one another and are, in particular, integrally designed.

[0039] The guide rail 1 is designed to be mirror-symmetrical with respect to a central plane E_M, which can also be referred to as the plane of symmetry. In this case, the central plane E_M is arranged orthogonally to the closing plane E_S. Therefore, the first retaining section 15 is mirror-symmetrical with respect to the second retaining section 15', and the first transition section 17 is mirror-symmetrical with respect to the second transition section 17'.

[0040] The guide rail 1 comprises a first switch element 19, which is pivotably arranged about a pivot axis L_S. The switch element 19 can be pivoted about the pivot axis L_S into an open position and a closed position. The pivot axis L_S is arranged parallel to the rotation axis L_D3 of the first guide element 3 of the first sliding door 2. The pivot axis L_S of the switch element 19 is skew and orthogonal to the center axis L_7 of the guide channel 7. The pivot axis L_S of the switch element 19 is also arranged outside the first guide channel 7. The pivot axis L_S is formed by a connecting element 26, which is connected to a rail center module 28.

[0041] In the open position, which is used, for example, for the first switch element 19 in Figure 2 , 3 and 6As shown, the first switch element 19 divides the first guide channel 7 into a first channel section 39 and a second channel section 40. In the Figures 2 and 3 For example, the first guide element 3 of the first sliding door 2 is arranged in the first channel section 39. The first channel section 39 is therefore located in the Figures 2 and 3 The first switch element 19 is located to the left of the first channel section 39, and the second channel section 40 is located to the right of the first switch element 19, without being limited to it. When the first switch element 19 is in the open position, the first switch element 19 blocks the transfer of the first guide element 3 of the first sliding door 2 from the first channel section 39 to the second channel section 40. The first channel section 39 is connected to the holding section 15 in such a way that the first guide element 3 of the first sliding door 2 can be transferred from the first channel section 39 to the holding section 15.

[0042] A first spring element 27 applies a first spring force to the first switch element 19, causing the switch element 19 to pivot into the open position. Thus, the first switch element 19 remains in the open position when unloaded. An unloaded state of the first switch element 19 exists, for example, when the first guide element 3 is located in the first channel section 39. A stop may be provided to limit the pivoting movement of the first switch element 19. In particular, this stop may be formed by the first wall 32 of the first guide channel 7.

[0043] In the closed position, the first switch element 19 releases the guide channel 7 such that the first channel section 39 and the second channel section 40 are connected. In the closed position of the first switch element 19, the first guide element 3' of the second sliding door 3' can be moved from the first channel section 39 to the second channel section 40. In the closed position of the first switch element 19, the guide channel 7 is separated from the holding section 15 by the first switch element 19.

[0044] The first switch element 19 comprises a separating section 20 and a switching section 23, which are arranged transversely to each other and connected in the area of ​​the pivot axis L_S. The first switch element 19 is L-shaped.

[0045] The separating section 20 is arranged in the guide channel 7 when the first switch element 19 is in the open position. When the first switch element 19 is in the closed position, the separating section 20 forms a section of the second wall 33 of the first guide channel 7 in the area of ​​the first opening. For this purpose, the separating section 20 has a straight channel wall surface 22 which, when the switch element 19 is in the closed position, forms the section of the second wall 33 of the first guide channel 7 in the area of ​​the first opening.

[0046] The separating section 20 also has a concave transition surface 21, which is arranged on one side of the separating section 20 opposite the channel wall surface 22. In the open position of the switch element 19, the concave transition surface 21 defines a transition channel 36, through which the first guide element 3 of the first sliding door 2 can be transferred from the guide channel 7, in particular from the first channel section 39, into the stopping section 15. The transition channel 36 is thereby bounded section by section by the guide channel 7 and the transition section 17.

[0047] The actuating section 23 of the first switch element 19 is located outside the guide channel 7 when the switch element 19 is in the open position. When the switch element 19 is in the closed position, the actuating section 23 defines the stopping section 15. The actuating section 23 comprises a concave transition surface 24 and a straight stopping section boundary surface 25 on one side, which defines the first stopping section 15 when the first switch element 19 is in the closed position.

[0048] The concave transition surface 24 of the actuating section 23 together with the concave transition surface 21 of the separating section 20 forms a concave actuating contour of the first switch element 19, which in the open position of the switch element 19 limits the transition channel 36.

[0049] When the first sliding door 2 is moved from the open position to the closed position, the first guide element 3 is initially guided in the first channel section 39. Subsequently, the first guide element 3 runs against the actuating contour of the first switch element 19. Due to the concave design of the actuating contour, the first guide element 3 is deflected radially with respect to the central axis L_7 and moved via the transfer channel 36 and the transfer section 17 in the direction of the first stopping section 15.

[0050] The contact force acting between the first guide element 3 and the first switch element 19 initially creates an opening torque that holds the first switch element 19 in the open position. Due to the concave design of the actuating contour, the line of action of this contact force moves with the progressive movement of the first guide element 3 towards the first holding section 15, in the direction of the first pivot axis L_S, and across it. After the line of action and the first pivot axis L_S intersect, the contact force creates a closing torque that pivots the first switch element 19 into the closed position. This pivots the actuating section 23 out of the area of ​​the first holding section 15, releasing it so that the first guide element 3 can enter the holding section 15. The guide element 3 can then be moved until it contacts the first contact surface 16.The closing torque also causes the separating section 20 to pivot out of the guide channel 7, so that the first channel area and the second channel area are connected.

[0051] The guide rail 1 also includes a second spring element 18, which in this case is designed as a spring tab extending from the first guide channel 7 into the transition section 17. The spring tab has a hook section 38 at its free end, extending from the spring tab in the direction of the pivot axis L_S. In the closed position of the first switch element 19, the first switch element 19 is in contact with the hook section 38, so that the first switch element 19 is held in the closed position by the hook section 38, as can be seen in particular from Figure 9This can be seen. When the first switch element 19 is pivoted from the closed position towards the open position, the second spring element 18 is initially deformed by the first switch element 19, allowing the first switch element 19 to move into the open position. In the open position, the first switch element 19 rests against the first wall 32 of the guide channel 7 and is held in the open position by the hook section 38 of the second spring element 18, as can be seen in particular from Figure 10 can be seen.

[0052] The second spring element 18 is moved at least section by section from the closed position to the open position via the pivoting path of the first switch element 19.

[0053] The second spring element 18 is connected to the first switch element 19 and applies a second spring force to it, creating a frictional connection between the second spring element 18 and the first switch element 19. This frictional force acts as a damping force with respect to the pivoting movement of the first switch element 19. The second spring element 18 is in contact with the actuating section 23 in both the open and closed positions. It is conceivable that the second spring element 18 is not in contact with the first switch element 19 in an intermediate position between the open and closed positions. Likewise, it is conceivable that the second spring element 18 is not in contact with the first switch element 19 in a position between the open and closed positions.

[0054] It is also conceivable that, during the transfer of the first guide element 3 in the area of ​​the transfer section 17, the first guide element 3 comes into contact with the spring tab, at least partially. This can cause the spring tab to move away from the first switch element 19, thus varying or reducing the frictional force between the spring tab and the first switch element 19.

[0055] The guide rail 1 includes a second switch element 19' which, in the open position, divides the first guide channel 7 into a third channel section and a fourth channel section. The third channel section is connected to the second holding section 15' such that the first guide element 3' of the second sliding door 2' can be moved from the third channel section into the second holding section 15'. In the closed position, the second switch element 19' releases the first guide channel 7 so that the first guide element 3 of the first sliding door 2 can be moved from the third channel section into the fourth channel section. The second switch element 19' is designed and arranged in a mirror-symmetrical manner with respect to the center plane E_M relative to the first switch element 19. Therefore, what was previously stated regarding the first switch element 19 applies analogously to the second switch element 19'.In this process, identical or corresponding features in the figures are marked with the same reference symbols together with an overline.

[0056] The first channel area defined by the first switch element 19 in the open position and the third channel area defined by the second switch element 19' in the open position overlap in an area between the first switch element 19 and the second switch element 19'.

[0057] As can be seen in particular from the combination of the Figure 7 and 8 The first holding element 4' of the second sliding door 2' has a transition section 37' which is designed such that the first guide element 3 of the first sliding door 2 can be guided past or through the first holding element 4' of the second sliding door 2'.

[0058] The guide rail 1 also includes a second guide channel 11, which is bounded by a first wall 34 and a second wall 35. The second guide element 5 of the first sliding door 2 and the second guide element 5' of the second sliding door 2' can be guided in the second guide channel 11. The second guide channel 11 is arranged offset from the first guide channel 7 with respect to the central axis L_7. The first retaining section 15 and the second retaining section 15' are arranged between the first guide channel 7 and the second guide channel 11.

[0059] The second guide channel 11 is formed by a central section 12, a first intermediate section 13, a second intermediate section 13', a first end section 14, and a second end section 14'. It is understood that the first intermediate section 13 and the second intermediate section 13' are optional, and the guide rail 1 can alternatively comprise more than one first intermediate section 13 and one second intermediate section 13'.

[0060] The central section 12, the first intermediate section 13, and the second intermediate section 13' extend along a central axis L_12. In this case, the central axis L_12 is straight. However, it is also conceivable that the central axis L_12 could have a shape other than straight. The central axis L_12 is parallel to the central axis L_7 of the first guide channel 7.

[0061] The first end section 14 extends along a first end axis L_14 and the second end section 14' along a second end axis L_14'. The first end axis L_14 and the second end axis L_14' are arranged perpendicular to the central axis L_12 and each form an acute angle with it.

[0062] In the respective area of ​​the intersection points of the central axis L_12 with the first end axis L_14 and the second end axis L_14', the second guide channel 11 can have a radius.

[0063] The guide rail 1 has a modular design and comprises a center rail module 28, a first intermediate rail module 29, a second intermediate rail module 29', a first end rail module 30, and a second end rail module 30'. It is understood that the first intermediate rail module 29 and the second intermediate rail module 29' are generally optional.
