Technical Field
[0001] The invention relates to a guide rail for a sliding door with guide elements, in particular for a furniture part. Background Art
[0002] The task of a guide rail for a sliding door is to guide the sliding door from a first position where the sliding door is open to a second position where the sliding door is closed. The guide rail can also take on the task of supporting the sliding door, so that the gravity acting on the sliding door is supported here.
[0003] DE 29 12 256 C2 discloses a guide rail on which two sliding doors are guided, and the two sliding doors are in a common plane when closed. The guide rail includes a central conversion part through which the two sliding doors are guided, and the central conversion part can swing so that the two sliding doors are in planes arranged parallel to each other and can slide relative to each other. The plane in which the sliding door is located in the open state intersects the plane in which the sliding door is located in the closed state. The guiding of the sliding door is respectively carried out by two guiding rollers of the guide rail and the central conversion part, and the guiding rollers are fitted into the grooves of the sliding door. Summary of the Invention
[0004] Herein, the present invention is based on the following task of providing a guide rail for a sliding door with guide elements, which enables stable guiding of the sliding door.
[0005] The task on which the present invention is based is solved by a guide rail for a sliding door with guide elements, which includes: a guiding channel extending along a central axis, in which the guide elements of the sliding door can be guided; a holding section; a conversion element that can swing about a swinging axis to an open position and a closed position, wherein in the open position, the conversion element divides the guiding channel into a first channel region and a second channel region, wherein the first channel region is connected to the holding section so that the guide elements of the sliding door can be transported from the first channel region to the holding section, and in the closed position, the conversion element releases the guiding channel so that the first channel region and the second channel region are connected to each other.
[0006] The guide rail according to the present invention has the following advantages that the guide elements of the sliding door are stably guided in the guiding channel and can be stably transported from the guiding channel to the holding section through the conversion element.
[0007] The guide rail can in particular be configured for at least one sliding door with at least one guide element. The at least one guide element can be configured as a guiding roller. Herein, the rotational axis of the guiding roller can be arranged parallel to the swinging axis of the conversion element.
[0008] In particular, the guide rails for at least one sliding door with two guide elements can each be configured in the form of guide rollers. Herein, the respective rotational axes of the two guide rollers can be arranged parallel to the rotational axis of the conversion element.
[0009] In a possible embodiment of the guide rail according to the invention, the guide channel can be divided into a first channel region and a second channel region in the open position of the conversion element, such that the guide element cannot be transported from the first channel region into the second channel region. In other words, the guide channel can be divided into a first channel region and a second channel region in the open position of the conversion element, such that the transport of the guide element from the first channel region into the second channel region is prevented.
[0010] In another possible embodiment, the conversion element can be swung from the open position to the closed position by the guide element. In particular, when the guide element is transported from the guide channel into the holding section, the conversion element can be swung from the open position to the closed position.
[0011] A further possible embodiment is that the swing axis of the conversion element is arranged inclined to the central axis of the guide channel. In particular, the swing axis of the conversion element can be arranged inclined or orthogonal to the central axis of the guide channel. In a possible embodiment, the swing axis of the conversion element can be arranged outside the guide channel.
[0012] In a possible configuration of the guide rail according to the invention, the conversion element can include a separating section, which is arranged in the guide channel in the open position and forms a section of the wall of the guide channel in the closed position. Herein, the separating section can have a concave transport surface and a straight channel wall surface. The concave transport surface can delimit a transport channel in the open position, through which the guide element can be transported from the guide channel into the holding section. Alternatively or in combination, the straight channel wall surface can form a section of the wall of the guide channel in the closed position.
[0013] In another possible configuration, the conversion element can include an adjusting section, which is arranged outside the guide channel in the open position and delimits the holding section in the closed position. Herein, the adjusting section can have a concave transport surface and a straight holding section boundary surface. The concave transport surface of the adjusting section can form an adjusting profile with the concave transport surface of the separating section, which delimits the transport channel in the open position. The straight holding section limiting surface can limit the holding section in the closed position. The conversion element can be configured in an L-shape. Herein, the separating section can be arranged transversely to the adjusting section. In particular, the longitudinal axis of the separating section can be arranged at a right angle to the longitudinal axis of the adjusting section.
[0014] In another possible configuration, a first spring element can be provided, which loads the switching element with a first spring force and causes the switching element to swing into the open position by the first spring force. For example, the first spring element can be configured as a helical spring, a torsion spring, a compression spring or a tension spring.
[0015] In another possible configuration, a second spring element can be provided, which abuts against the switching element in the open position of the switching element, such that the switching element is held in the open position by the second spring element. Alternatively or in combination, the second spring element can abut against the switching element in the closed position of the switching element, such that the switching element is held in the closed position by the second spring element. The second spring element can hereby abut against the switching element such that a frictional engagement or a form-fit connection is established between the second spring element and the switching element.
[0016] A frictional force can be generated at least sectionally between the second spring element and the switching element on the swinging path of the switching element from the closed position to the open position, and this frictional force can also be referred to as a damping force with respect to the swinging movement of the switching element. Furthermore, in one configuration it can be that the second spring force of the second spring element can be changed by the guide element when the guide element is transported from the guide channel into the holding section.
[0017] In a possible embodiment, the second spring element can have a hook section, which abuts against the switching element in the open position of the switching element and holds the switching element in the open position by the hook section. Alternatively or in combination, the hook section can abut against the switching element in the closed position of the switching element, such that the switching element is held in the closed position by the hook section. Hereby, the second spring element can be configured as a spring leaf, which has a hook section at the free end. The guide rail can combinatorially include the first spring element and the second spring element. Alternatively, it can also be envisaged that the guide rail includes one of the first spring element and the second spring element.
[0018] In a possible embodiment of the guide rail according to the invention, the holding section can be arranged radially overlapping with the guide channel. The arrangement of the holding section radially overlapping with the guide channel should hereby be understood as that the holding section is at least partially arranged in a plane arranged at right angles to the central axis of the first guide channel.
[0019] In another possible embodiment, it can be provided that a guiding element for guiding another sliding door in the guiding channel is provided with another holding section and another switching element. The another switching element can swing about another swinging axis to an open position and a closed position, wherein the swinging of the another switching element from the open position to the closed position is carried out in the opposite direction to the swinging of the switching element, such that the switching element divides the guiding channel into a third channel region and a fourth channel region in the open position, wherein the third channel region is connected to the another holding section, such that the guiding element of the another sliding door can be transported from the third channel region to the another holding section, and the another switching element releases the guiding channel in the closed position, such that the third channel region is connected to the fourth channel region, wherein in particular the guiding element of the sliding door can be guided from the third channel region into the fourth channel region.
[0020] In another possible embodiment, in the open position, the guiding channel can be divided into a third channel region and a fourth channel region by the another switching element, such that the guiding element of the another sliding door cannot be transported from the third channel region to the fourth channel region.
[0021] In another possible embodiment, another guiding channel is provided, which has a central section parallel to and spaced from the central axis of the guiding channel, and has a first end section and a second end section, which are respectively arranged laterally and spaced from the central axis of a guiding channel. The another guiding element of the sliding door and / or the another guiding element of the another sliding door can be guided in the another guiding channel. Description of the Drawings

[0033] Illustrated below together in Figures 1 to 10 is the guide rail 1 according to the invention, which is fastened to the base of the furniture 31. In the present case, it is the lower base of the furniture 31, wherein it is also conceivable that the guide rail 1 is fastened to the upper base of the furniture 31. The guide rail 1 is configured here to guide the first sliding door 2 and the second sliding door 2'. The first sliding door 2 and the second sliding door 2' can hereby be guided by the guide rail 1 from the closed position (in which the respective sliding door closes the corresponding part of the furniture 31 corresponding to this sliding door) to the open position (in which the respective sliding door releases the corresponding part of the furniture corresponding to this sliding door). In the fully closed position, the first sliding door 2 and the second sliding door 2' are respectively located in a closing plane E_S. In the fully open position, the first sliding door 2 is located in a first opening plane E_O, while the second sliding door is located in a second opening plane. Currently, the first opening plane E_O and the second opening plane are in the same plane, but this is not limiting. In the present case, the first opening plane E_O and the second opening plane are arranged parallel to and spaced apart 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, in particular enclosing an acute angle.
[0034] The first sliding door 2 includes a first guiding element 3 in the form of a guiding roller, which is connected to the first sliding door 2 by a first holding element 4. The first sliding door 2 further includes a second guiding element 5, which is connected to the first sliding door 2 by a second holding element 6. The first guiding element 3 of the first sliding door 2 has a rotational axis L_D3, which is arranged parallel to and in particular spaced apart from the first sliding door 2. The rotational axis L_D3 of the first guiding 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 guiding element 5 of the first sliding door 2 has a rotational axis L_D5, which is arranged parallel to and in particular spaced apart from the first sliding door 2. The rotational axis L_D5 of the second guiding element 5 of the first sliding door 2 is also arranged parallel to and in particular spaced apart from the closing plane E_S.
[0035] The second sliding door 2' includes a first guiding element 3' in the form of a guiding roller, which is connected to the second sliding door 2' by a first holding element 4'. The second sliding door 2' further includes a second guiding element 5', which is connected to the second sliding door 2' by a second holding element 6'. The first guiding element 3' of the second sliding door 2' has a rotational axis L_D3', which is arranged parallel to and in particular spaced apart from the second sliding door 2'. The rotational axis L_D3' of the first guiding 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 guiding element 5' of the second sliding door 2' has a rotational axis L_D5', which is arranged parallel to and in particular spaced apart from the second sliding door 2'. The rotational axis L_D5' of the second guiding element 5' of the second sliding door 2' is also arranged parallel to and in particular spaced apart from the closing plane E_S.
[0036] The guide rail 1 includes a first guiding channel 7 extending along a center line axis L_7. In the present case, the center axis L_7 is implemented straight, and the center axis L_7 can also be referred to as the longitudinal axis of the first guiding channel 7. However, in principle, it is also conceivable that the center axis L_7 has a shape deviating from a straight line.
[0037] The first guiding 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 at least sectionally substantially constant.
[0038] The first retaining section 15 is arranged radially overlapping with the first guide channel 7, and the first retaining section 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 retaining section 15. The first retaining section 15 is delimited by a contact surface 16 against which the first guide element 3 of the first sliding door 2 can bear. Thus, the movement of the first guide element 3 or the first sliding door 2 can be delimited by the contact surface 16. In this regard, the contact surface 16 can also be referred to as a delimiting stop.
[0039] The second retaining section 15' is arranged radially overlapping with the first guide channel 7, and the second retaining section is connected to the first guide channel 7 such 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 respective retaining section arranged radially overlapping with the first guide channel 7 is to be understood here as meaning that the respective retaining section is at least partially arranged in a plane arranged at right angles to the central axis L_7 of the first guide channel 7.
[0040] The first retaining section 15 is arranged spaced apart from the first guide channel 7 in the radial direction with respect to the central axis L_7 of the first guide channel 7. The second retaining section 15' is arranged spaced apart from the first guide channel 7 in the radial direction with respect to the central axis L_7 of the first guide channel 7. In the present case, the first retaining section 15 and the second retaining section 15' are arranged spaced apart from the first guide channel 7 by the same amount in the radial direction with respect to the central axis L_7 of the first guide channel 7. However, it is also conceivable that the first retaining section 15 and the second retaining section 15' are arranged spaced apart from the first guide channel 7 by different amounts in the radial direction with respect to the central axis L_7 of the first guide channel 7.
[0041] The first retaining section 15 and the second retaining section 15' are arranged spaced apart from each other along the central axis L_7 of the first guide channel 7. In the present case, the first retaining section 15 and the second retaining section 15' are configured to be spatially separated from each other. In principle, it is also conceivable to connect the first retaining section 15 and the second retaining section 15', to transition into each other and / or to be configured integrally with each other.
[0042] The second retaining section 15' is delimited by a contact surface 16' against which the first guide element 3' of the second sliding door 2' can bear. Thus, the movement of the first guide element 3' or the second sliding door 2' can be restricted by the contact surface 16'. In this regard, the contact surface 16' can also be referred to as a delimiting stop.
[0043] The first guide channel 7 is connected to the first holding section 15 via the first conveying section 17. Here, the first conveying section 17 extends through the second wall 33 of the guide channel 7. Accordingly, the second wall 33 is interrupted in the region of the first conveying section 17. In other words, the second wall 33 has a first interruption in the region of the first conveying section 17.
[0044] The first guide channel 7 is connected to the second holding section 15' via the second conveying section 17'. Here, the second conveying section 17' extends through the second wall 33 of the guide channel 7. Accordingly, the second wall 33 is interrupted in the region of the second conveying section 17'. In other words, the second wall 33 has a second interruption in the region of the second conveying section 17'. In the present case, the second interruption is arranged spaced apart from the first interruption in the direction of the central axis L_7. However, it is also conceivable that the first interruption and the second interruption transition into one another and are in particular integrally configured.
[0045] The guide rail 1 is configured mirror-symmetrically with respect to a central plane E_M, which can also be referred to as a symmetry plane. Currently, the central plane E_M is arranged orthogonally to the closing plane E_S. Accordingly, the first holding section 15 and the second holding section 15' are configured mirror-symmetrically, while the first conveying section 17 and the second conveying section 17' are configured mirror-symmetrically.
[0046] The guide rail 1 includes a first switching element 19 arranged to be pivotable about a pivot axis L_S. The switching element 19 can be pivoted about the pivot axis L_S into an open position and a closed position here. The pivot axis L_S of the switching element 19 is arranged parallel to the rotational axis L_D3 of the first guide element 3 of the first sliding door 2. The pivot axis L_S of the switching element 19 is arranged inclinedly and orthogonally with respect to the central axis L_7 of the guide channel 7. The pivot axis L_S of the switching element 19 is also arranged outside the first guide channel 7. The pivot axis L_S is formed by a connecting element 26 here, which is connected to the track center module 28.
[0047] For example, in Figure 2 、 Figure 3 and Figure 6 In the open position of the first switching element 19 shown, the first switching element 19 divides the first guide channel 7 into a first channel region 39 and a second channel region 40. For example, in Figure 2 and Figure 3 , the first guide element 3 of the first sliding door 2 is arranged in the first channel region 39. Accordingly, in Figure 2 and Figure 3In this case, the first channel region 39 is located to the left of the first switching element 19, and the second channel region 40 is located to the right of the first switching element 19, but is not limited thereto. In the open position of the first switching element 19, the first guide element 3 of the first sliding door 2 is blocked by the first switching element 19 when being transported from the first channel region 39 to the second channel region 40. The first channel region 39 is connected to the holding section 15 here, such that the first guide element 3 of the first sliding door 2 can be transported from the first channel region 39 to the holding section 15.
[0048] The first spring element 27 exerts a first spring force on the first switching element 19, causing the switching element 19 to swing into the open position by the first spring force. Thus, the first switching element 19 remains in the open position in the unloaded state. For example, when the first guide element 3 is arranged in the first channel region 39, the first switching element 19 is in the unloaded state. Here, a stop can be provided, which delimits the swinging movement of the first switching element 19. In particular, the stop can be formed by the first wall 32 of the first guide channel 7.
[0049] In the closed position, the first switching element 19 releases the guide channel 7, connecting the first channel region 39 and the second channel region 40 to each other. In the closed position of the first switching element 19, the first guide element 3' of the second sliding door 3' can be transported from the first channel region 39 to the second channel region 40. In the closed position of the first switching element 19, the guide channel 7 is separated from the holding section 15 by the first switching element 19.
[0050] The first switching element 19 includes 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 swinging axis L_S. The first switching element 19 is configured in an L-shape.
[0051] In the open position of the first switching element 19, the separating section 20 is arranged in the guide channel 7. In the closed position of the first switching 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 interruption. For this purpose, the separating section 20 has a straight channel wall surface 22, which forms a section of the second wall 33 of the first guide channel 7 in the region of the first interruption in the closed position of the switching element 19.
[0052] The separating section 20 also has a concave conveying surface 21 which is arranged on the side of the separating section 20 opposite to the channel wall surface 22. In the open position of the switching element 19, the concave conveying surface 21 delimits a conveying channel 36 through which the first guiding element 3 of the first sliding door 2 can be conveyed from the guiding channel 7, in particular from the first channel region 39, into the holding section 15. The conveying channel 36 is delimited sectionally here by the guiding channel 7 and the conveying section 17.
[0053] In the open position of the switching element 19, the adjusting section 23 of the first switching element 19 is arranged outside the guiding channel 7. In the closed position of the switching element 19, the adjusting section 23 delimits the holding section 15. The adjusting section 23 includes a concave conveying surface 24 and a straight holding-section delimiting surface 25 on one side, and in the closed position of the first switching element 19, the straight holding-section delimiting surface delimits the first holding section 15.
[0054] Together with the concave conveying surface 21 of the separating section 20, the concave conveying surface 24 of the adjusting section 23 forms a concave adjusting profile of the first switching element 19 which, in the open position of the switching element 19, delimits the conveying channel 36.
[0055] When the first sliding door 2 is conveyed from the open position into the closed position, the first guiding element 3 is first guided in the first channel region 39. Then, the first guiding element 3 abuts against the adjusting profile of the first switching element 19. Due to the concave configuration of the adjusting profile, the first guiding element 3 is deflected radially with respect to the central axis L_7 and moves in the direction of the first holding section 15 through the conveying channel 36 and the conveying section 17.
[0056] The contact force acting between the first guiding element 3 and the first switching element 19 initially generates an opening moment which holds the first switching element 19 in the open position. Due to the concave configuration of the adjusting profile, the line of action of the mentioned contact force moves in the direction of the first swivel axis L_S as the first guiding element 3 progresses in the direction of the first holding section 15 and extends beyond the first swivel axis. After the line of action of the force intersects the first swivel axis L_S, the contact force generates a closing moment which swings the first switching element 19 into the closed position. As a result, the adjusting section 23 swings out of the region of the first holding section 15 and releases the first holding section so that the first guiding element 3 can enter the holding section 15. Then, the guiding element 3 can abut against the first abutment surface 16. The closing moment also swings the separating section 20 out of the guiding channel 7, connecting the first channel region and the second channel region to each other.
[0057] The guide rail 1 further includes a second spring element 18, which is currently configured as a spring leaf that extends from the first guide channel 7 into the conveying section 17. The spring leaf has a hook section 38 at its free end, which extends from the spring leaf in the direction of the swing axis L_S. In the closed position of the first switching element 19, the first switching element 19 abuts against the hook section 38, so that the first switching element 19 is held in the closed position by the hook section 38, especially from Figure 9 visible. If the first switching element 19 swings out in the direction from the closed position to the open position, the second spring element 18 is first deformed by the first switching element 19, thereby guiding the first switching element 19 into the open position. In the open position, the first switching element 19 abuts 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, especially from Figure 10 visible.
[0058] Through the swing path of the first switching element 19 from the closed position to the open position, the second spring element 18 at least sectionally abuts against the first switching element 19 and loads the first switching element 19 with a second spring force, thereby establishing a frictional connection between the second spring element 18 and the first switching element 19. Here, the frictional force acts as a damping force for the swing movement of the first switching element 19. The second spring element 18 currently abuts against the adjusting section 23 both in the open position and the closed position. It can be imagined here that the second spring element 18 does not abut against the first switching element 19 in the intermediate position between the open position and the closed position. In principle, it can also be imagined that the second spring element 18 does not abut against the first switching element 19 in the position between the open position and the closed position.
[0059] It can also be imagined that when the first guide element 3 is conveyed in the region of the conveying section 17, the first guide element 3 at least regionally abuts against the spring leaf. Thereby, the spring leaf can move away from the first switching element 19, thereby changing or reducing the frictional force between the spring leaf and the first switching element 19.
[0060] The guide rail 1 includes a second switching element 19', which divides the first guide channel 7 into a third channel region and a fourth channel region in the open position, 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 transported from the third channel region into the second holding section 15'. In the closed position, the second switching element 19' releases the first guide channel 7 such that the first guide element 3 of the first sliding door 2 is guided from the third channel region into the fourth channel region. The second switching element 19' is configured and arranged mirror-symmetrically to the first switching element 19 with respect to the central plane E_M. In this regard, the explanations made previously for the first switching element 19 also apply to the second switching element 19'. In the figures, identical or corresponding features are marked with the same reference signs and overbars.
[0061] In the region between the first switching element 19 and the second switching element 19', the first channel region defined by the first switching element 19 in the open position and the third channel region defined by the second switching element 19' in the open position overlap.
[0062] In particular, from Figure 7 and Figure 8 it can be seen from the combination that the first holding element 4' of the second sliding door 2' has a transport section 37' which is configured to enable the first guide element 3 of the first sliding door 2 to be guided past or through the first holding element 4' of the second sliding door 2'.
[0063] The guide rail 1 further includes a second guide channel 11 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 spaced apart from the first guide channel 7 with respect to the central axis L_7. The first holding section 15 and the second holding section 15' are arranged between the first guide channel 7 and the second guide channel 11 here.
[0064] The second guide channel 11 consists of 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 should be understood that the first intermediate section 13 and the second intermediate section 13' are optional, and the guide rail 1 can alternatively also include more than one first intermediate section 13 and second intermediate section 13'.
