[0001] Guide rail for a sliding door with one guide element

[0002] Description

[0003] The present invention relates to a guide rail for a sliding door with a guide element, in particular for a piece of furniture.

[0004] Guide rails for sliding doors are designed to guide the movement of the sliding door from a first position, where the sliding door is open, to a second position, where the sliding door is closed. Guide rails can also support the sliding door, thereby supporting the weight acting on it.

[0005] DE 29 12 256 C2 discloses a guide rail on which two sliding doors are guided, which lie in a common plane when closed. The guide rail comprises a center switch 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 on the guide rail and the center switch, which engage in a groove in the sliding doors.

[0006] Based on this, the present invention is based on the object of providing a guide rail for a sliding door with a guide element which enables stable guidance of the sliding doors.

[0007] The object underlying the present invention is achieved by a guide rail for a sliding door with a guide element, comprising: a guide channel which extends along a central axis and in which the guide element of the sliding door can be guided, a holding section, a switch element which can be pivoted about a pivot axis into an open position and into a closed position, wherein the switch element in the open position divides the guide channel into a first channel region and a second channel region, wherein the first channel region is connected to the holding section in such a way that the guide element of the sliding door can be transferred from the first channel region into the holding section, and the switch element in the closed position releases the guide channel in such a way that the first channel region and the second channel region are connected to one another.

[0008] The guide rail according to the invention has the advantage that the guide element of the sliding door can be stably guided within the guide channel and can be stably transferred from the guide channel into the holder section via the switch element.

[0009] The guide rail can be designed, in particular, for at least one sliding door with at least one guide element. The at least one guide element can be designed as a guide roller. The rotation axis of the guide roller can be arranged parallel to the pivot axis of the switch element.

[0010] Specifically, the guide rail for at least one sliding door can be configured with two guide elements, each in the form of a guide roller. The rotational axis of each of the two guide rollers can be arranged parallel to the pivot axis of the switch element.

[0011] In one possible embodiment of the guide rail according to the invention, the guide channel can be divided into the first channel region and the second channel region in the open position of the switch element in such a way that the guide element cannot be transferred from the first channel region into the second channel region. In other words, the guide channel can be divided into the first channel region and the second channel region in the open position of the switch element in such a way that a transfer of the guide element from the first channel region to the second channel region is blocked. In a further possible embodiment, the switch element can be pivoted by the guide element from the open position to the closed position. In particular, the switch element can be pivoted from the open position to the closed position when the guide element is transferred from the guide channel to the holding section.

[0012] Furthermore, an embodiment is possible in which the pivot axis of the switch element is arranged skew to the center axis of the guide channel. In particular, the pivot axis of the switch element can be arranged skew and orthogonal to the center axis of the guide channel. In one possible embodiment, the pivot axis of the switch element can be arranged outside the guide channel.

[0013] 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 a wall of the guide channel. The separating section can have a concave transfer surface and a straight channel wall surface. In the open position, the concave transfer surface can define a transfer channel via which the guide element can be transferred from the guide channel into the holding section. Alternatively, or in combination, the straight channel wall surface can form the section of the wall of the guide channel in the closed position.

[0014] In a further possible embodiment, the switch element can comprise an adjusting section which, in the open position, is arranged outside the guide channel and, in the closed position, delimits the holding section. In this case, the adjusting section can have a concave transfer surface and a straight holding section delimiting surface. The concave transfer surface of the adjusting section can form an adjusting contour with the concave transfer surface of the separating section, which delimits the transfer channel in the open position. The straight holding section delimiting surface can delimit the holding section in the closed position. The switch element can be L-shaped. The separating section can be arranged transversely to the adjusting section. In particular, a longitudinal axis of the separating section can be arranged at a right angle to the longitudinal axis of the adjusting section.

[0015] In another possible embodiment, a first spring element can be provided that applies a first spring force to the switch element, so that the switch element is pivoted into the open position by the first spring force. The first spring element can be designed, for example, as a spiral spring, torsion spring, compression spring, or tension spring.

[0016] In a further 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 such 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 of the switch element such 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 such that a frictional or positive connection is established between the second spring element and the switch element.

[0017] A frictional force can act between the second spring element and the switch element, at least in sections, along the pivoting path of the switch element from the closed position to the open position. This frictional force can also be referred to as a damping force with respect to the pivoting movement of the switch element. Furthermore, in one embodiment, it is possible for the second spring force of the second spring element to be variable when the guide element is transferred from the guide channel into the holding section.

[0018] In one possible embodiment, the second spring element can have a hook portion 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 portion. Alternatively or in combination, the hook portion can be in contact with the switch element in the closed position of the switch element such that the switch element is held in the closed position by the hook portion. In this case, the second spring element can be designed as a spring tab which has the hook portion at a free end. The guide rail can comprise the first spring element and the second spring element in combination. Alternatively, it is also conceivable for the guide rail to comprise one of the first spring element and the second spring element.

[0019] In one possible embodiment of the guide rail according to the invention, the holding section can be arranged in radial overlap with the guide channel. The arrangement of the holding section in radial overlap with the guide channel should be understood to mean that the holding section is arranged at least partially in a plane that is perpendicular to the center axis of the first guide channel.

[0020] In a further 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 in the further switch element takes place 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 region and a fourth channel region, wherein the third channel region 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 region into the further holding section, and that the further switch element in the closed position releases the guide channel in such a way,that 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.,

[0021] In a further possible embodiment, the guide channel in the open position can be divided into the third channel area and the fourth channel area by the further switch element in such a way that the guide element of the further sliding door cannot be transferred from the third channel area into the fourth channel area.

[0022] In a further possible embodiment, a further guide channel can be provided which has a central section which is arranged parallel and spaced from the central axis of the one guide channel, as well as a first end section and a second end section which are each spaced from and arranged transversely to the central axis of the one guide channel, wherein a further guide element of the sliding door can be guided in the further guide channel and / or a further guide element of the further sliding door can be guided.

[0023] An embodiment is explained below with reference to the figures.

[0024] Figure 1 shows a view of a floor 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;

[0025] Figure 2 shows the guide rail from Figure 1, with a first sliding door shown in a partially open position and a second sliding door shown in a closed position;

[0026] Figure 3 shows the guide rail from Figure 1, with the first sliding door shown in the open position and the second sliding door shown in the closed position;

[0027] Figure 4 shows the rail center module of the guide rail from Figure 1, wherein a first switch element and a second switch element are each arranged in the closed position;

[0028] Figure 5 shows the rail center module of the guide rail from Figure 1 together with the first and second sliding doors in the closed position, Figure 6 shows the rail center module of the guide rail from Figure 1 together with the first sliding door in the partially open position and the second sliding door in the closed position;

[0029] Figure ? the rail center module of the guide rail from Figure 1 together with the first sliding door in an intermediate position and the second sliding door in the closed position;

[0030] Figure 8 is a cross-section through the guide rails of Figure 1 along the section plane VIII-VIII of Figure 7, wherein the first guide roller of the first sliding door and the first holding element of the second sliding door are arranged in the section plane,

[0031] Figure 9 shows a section through the hook section of the second spring element with the switch element in the closed position; and

[0032] Figure 10 shows a section through the hook section of the second spring element with the switch element in the open position.

[0033] Figures 1 to 10, which are described together below, show a guide rail 1 according to the invention which is fastened to a base of a piece of furniture 31. In the present case, this is the bottom floor of the piece of furniture 31, although it is also conceivable for the guide rail 1 to be fastened to an upper floor of the piece of furniture 31. The guide rail 1 is designed 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 via the guide rail 1 from a closed position, in which the respective sliding door closes a part of the piece of furniture 31 assigned to the sliding door, to an open position, in which the respective sliding door exposes the part of the furniture assigned to 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. The first opening plane E_O and the second opening plane lie in the same plane, but are not limited thereto. In the present case, the first opening plane E_O and the second opening plane are arranged parallel and spaced from the closing plane E_S. However, it is also conceivable that the first opening plane E_O and the second opening plane are arranged transversely to the closing plane E_S and, in particular, enclose an acute angle.

[0034] 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 holding 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 holding element 6. The first guide element 3 of the first sliding door 2 has a rotation axis L_D3, which is arranged parallel to and in particular at a distance from the first sliding door 2. The rotation axis L_D3 of the first guide element 3 of the first sliding door 2 is also arranged parallel to and in particular at a distance from the closing plane E_S. The second guide element 5 of the first sliding door 2 has a rotation axis L_D5, which is arranged parallel to and in particular at a distance from the first sliding door 2. The rotation axis L_D5 of the second guide element 5 of the first sliding door 2 is also arranged parallel to and in particular at a distance from the closing plane E_S.

[0035] 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 holding 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 holding element 6'. The first guide element 3' of the second sliding door 2' has a rotation axis L_D3', which is arranged parallel to and in particular at a distance from the second sliding door 2'. The rotation axis L_D3' of the first guide element 3' of the second sliding door 2' is also arranged parallel to and in particular at a distance from the closing plane E_S. The second guide element 5' of the second sliding door 2' has a rotation axis L_D5', which is arranged parallel to and in particular at a distance from the second sliding door 2'.The rotation axis L_D5' of the second guide element 5' of the second sliding door 2' is also arranged parallel and in particular at a distance from the closing plane E_S.

[0036] The guide rail 1 comprises a first guide channel 7 extending along a center axis L_7. In this case, the center axis L_7 is straight, so that the center axis L_7 can also be referred to as the longitudinal axis of the first guide channel 7. However, it is also conceivable for the center axis L_7 to have a shape other than straight.

[0037] The first guide channel 7 is delimited 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.

[0038] A first holding section 15 is arranged radially overlapping the first guide channel 7 and is connected to the first guide channel 7 such that the first guide element 3 of the first sliding door 2 can be guided from the first guide channel 7 into the first holding section 15. The first holding section 15 is delimited 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 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.

[0039] A second holding section 15' is arranged in radial overlap with 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 holding section 15'. The arrangement of the respective holding sections in radial overlap with the first guide channel 7 should be understood such that the respective holding section is arranged at least partially in a plane that is arranged at a right angle to the center axis L_7 of the first guide channel 7.

[0040] The first holding section 15 is arranged at a distance from the first guide channel 7 in the radial direction with respect to the center axis L_7 of the first guide channel 7. The second holding section 15' is arranged at a distance from the first guide channel 7 in the radial direction with respect to the center axis L_7 of the first guide channel 7. In the present case, the first holding section 15 and the second holding section 15' are arranged at a distance from the first guide channel 7 by the same amount in the radial direction with respect to the center axis L_7 of the first guide channel 7. However, it is also conceivable that the first holding section 15 and the second holding section 15' are arranged at a distance from the first guide channel 7 by different amounts in the radial direction with respect to the center axis L_7 of the first guide channel 7.

[0041] The first holding section 15 and the second holding section 15' are arranged at a distance from one another along the center axis L_7 of the first guide channel 7. In the present case, the first holding section 15 and the second holding section 15' are spatially separated from one another. However, it is also conceivable in principle for the first holding section 15 and the second holding section 15' to be connected, merge into one another, and / or be integrally formed with one another.

[0042] The second holding section 15' is limited by a contact surface 16', with 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' or 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.

[0043] The first guide channel 7 is connected to the first holding section 15 via a first transfer section 17. The first transfer section 17 extends through the second wall 33 of the guide channel 7. The second wall 33 is thus interrupted in the region of the first transfer section 17. In other words, the second wall 33 has a first opening in the region of the first transfer section 17.

[0044] The first guide channel 7 is connected to the second holding section 15' via a second transfer section 17'. The second transfer section 17' extends through the second wall 33 of the guide channel 7. The second wall 33 is thus interrupted in the region of the second transfer section 17'. In other words, the second wall 33 has a second opening in the region of the second transfer section 17'. In the present case, the second opening is arranged at a distance from the first opening in the direction of the center axis L_7. However, it is also conceivable for the first opening and the second opening to merge into one another and, in particular, to be designed integrally.

[0045] The guide rail 1 is designed to be mirror-symmetrical with respect to a center plane E_M, which can also be referred to as a plane of symmetry. In this case, the center plane E_M is arranged orthogonally to the closing plane E_S. Therefore, the first holding section 15 is designed to be mirror-symmetrical with respect to the second holding section 15', and the first transfer section 17 is designed to be mirror-symmetrical with respect to the second transfer section 17'.

[0046] The guide rail 1 comprises a first switch element 19, which is pivotable about a pivot axis L_S. The switch element 19 can be pivoted about the pivot axis L_S into an open position and into 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 skewed 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.

[0047] In the open position, which is shown, for example, for the first switch element 19 in Figures 2, 3 and 6, the first switch element 19 divides the first guide channel 7 into a first channel region 39 and a second channel region 40. In Figures 2 and 3, for example, the first guide element 3 of the first sliding door 2 is arranged in the first channel region 39. The first channel region 39 is thus located to the left of the first switch element 19 in Figures 2 and 3, and the second channel region 40 is located to the right of the first switch element 19, without being limited thereto. A transfer of the first guide element 3 of the first sliding door 2 from the first channel region 39 to the second channel region 40 is blocked by the first switch element 19 when the first switch element 19 is in the open position.The first channel region 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 region 39 into the holding section 15.

[0048] A first spring element 27 applies a first spring force to the first switch element 19, so that the switch element 19 is pivoted into the open position by the first spring force. Thus, the first switch element 19 remains in the open position in the unloaded state. An unloaded state of the first switch element 19 exists, for example, when the first guide element 3 is arranged in the first channel region 39. A stop can be provided that limits the pivoting movement of the first switch element 19. In particular, this stop can be formed by the first wall 32 of the first guide channel 7.

[0049] In the closed position, the first switch element 19 releases the guide channel 7 such that the first channel region 39 and the second channel region 40 are connected to one another. In the closed position of the first switch element 19, the first guide element 3' of the second sliding door 3' can be transferred from the first channel region 39 into the second channel region 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.

[0050] The first switch element 19 comprises a separating section 20 and an adjusting section 23, which are arranged transversely to each other and are connected to each other in the region of the pivot axis L_S. The first switch element 19 is L-shaped.

[0051] The separating section 20 is arranged in the guide channel 7 in the open position of the first switch element 19. In the closed position of the first switch element 19, the separating section 20 forms a section of the second wall 33 of the first guide channel 7 in the region of the first opening. For this purpose, the separating section 20 has a straight channel wall surface 22, which, in the closed position of the switch element 19, forms the section of the second wall 33 of the first guide channel 7 in the region of the first opening.

[0052] The separating section 20 also has a concave transfer surface 21, which is arranged on a side of the separating section 20 opposite the channel wall surface 22. In the open position of the switch element 19, the concave transfer surface 21 defines a transfer channel 36, via 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 region 39, into the holding section 15. The transfer channel 36 is delimited in sections by the guide channel 7 and the transfer section 17.

[0053] The adjusting section 23 of the first switch element 19 is arranged outside the guide channel 7 in the open position of the switch element 19. In the closed position of the switch element 19, the adjusting section 23 delimits the holding section 15. The adjusting section 23 comprises on one side a concave transfer surface 24 and a straight holding section delimiting surface 25, which delimits the first holding section 15 in the closed position of the first switch element 19.

[0054] The concave transfer surface 24 of the actuating section 23, together with the concave transfer surface 21 of the separating section 20, forms a concave actuating contour of the first switch element 19, which delimits the transfer channel 36 in the open position of the switch element 19.

[0055] When transferring the first sliding door 2 from the open position to the closed position, the first guide element 3 is initially guided in the first channel region 39. Subsequently, the first guide element 3 runs against the adjusting contour of the first switch element 19. Due to the concave design of the adjusting contour, the first guide element 3 is deflected radially with respect to the center axis L_7 and moved via the transfer channel 36 and the transfer section 17 in the direction of the first holding section 15.

[0056] The contact force acting between the first guide element 3 and the first switch element 19 initially causes an opening moment that holds the first switch element 19 in the open position. Due to the concave design of the adjusting contour, the line of action of the said contact force migrates as the first guide element 3 moves towards the first holding section 15 in the direction of the first pivot axis L_S and beyond it. After the line of action of the force and the first pivot axis L_S have intersected, the contact force causes a closing moment that pivots the first switch element 19 into the closed position. As a result, the adjusting section 23 is pivoted out of the area of ​​the first holding section 15 and releases it, so that the first guide element 3 can enter the holding section 15. The guide element 3 can then be brought into contact with the first contact surface 16.The closing moment also pivots the separating section 20 out of the guide channel 7 so that the first channel area and the second channel area are connected to each other.

[0057] The guide rail 1 also comprises a second spring element 18, which in this case is designed as a spring tab that extends from the first guide channel 7 into the transfer section 17. The spring tab has a hook section 38 at its free end, which extends 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 rests against the hook section 38, such 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 9. If the first switch element 19 is pivoted out of the closed position towards the open position, the second spring element 18 is first deformed by the first switch element 19, such that the first switch element 19 can be guided 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 portion 38 of the second spring element 18, as can be seen in particular from Figure 10.

[0058] The second spring element 18 is in contact with the first switch element 19 at least in sections over the pivoting path of the first switch element 19 from the closed position to the open position and applies a second spring force to the first switch element 19, such that a frictional connection is established between the second spring element 18 and the first switch element 19. The frictional force acts as a damping force with regard to the pivoting movement of the first switch element 19. In the present case, the second spring element 18 is in contact with the adjusting section 23 in the open position and in the closed position. 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 position and the closed position. It is equally conceivable in principle that the second spring element 18 is not in contact with the first switch element 19 in one of the open and closed positions.

[0059] It is also conceivable that, during transfer of the first guide element 3 in the region of the transfer section 17, the first guide element 3 comes into contact with the spring tab, at least in some areas. This allows the spring tab to be moved away from the first switch element 19, so that the frictional force between the spring tab and the first switch element 19 is varied or reduced.

[0060] The guide rail 1 comprises a second switch element 19', which in the open position divides the first guide channel 7 into a third channel region and a fourth channel region, wherein the third channel region is connected to the second holding section 15' such that the first guide element 3' of the second sliding door 2' can be transferred from the third channel region into the second holding section 15'. In the closed position, the second switch element 19' releases the first guide channel 7 such that the first guide element 3 of the first sliding door 2 can be guided from the third channel region into the fourth channel region. The second switch element 19' is designed and arranged mirror-symmetrically to the first switch element 19 with respect to the center plane E_M. In this respect, what was previously stated in the context of the first switch element 19 applies analogously to the second switch element 19'.In the figures, identical or corresponding features are identified by the same reference numerals together with an overline. The first channel region defined by the first switch element 19 in the open position and the third channel region defined by the second switch element 19' in the open position overlap in a region between the first switch element 19 and the second switch element 19'.

[0061] As can be seen in particular from the combination of Figures 7 and 8, the first holding element 4' of the second sliding door 2' has a transfer 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'.

[0062] The guide rail 1 also comprises a second guide channel 11, which is delimited by a first wall 34 and a second wall 35.
