Description

Technical Field

[0001] The present invention relates to a sliding door accessory for a sliding door assembly. Background Art

[0002] The task of a sliding door fitting for a piece of furniture is to move the sliding door from a first position (in which the sliding door is open and the piece of furniture is accessible) to a second position (in which the sliding door is closed and the piece of furniture is closed). In addition, the sliding door fitting can assume the task of supporting the sliding door and thereby support the weight forces acting on the sliding door.

[0003] DE 37 31 123 A1 discloses a device for guiding a sliding door element, which device has a first slide and a second slide, which slides can each be moved into a closed position and an open position. Summary of the invention

[0004] On this basis, the present invention is based on the following object, and proposes a sliding door fitting for guiding a first sliding door and a second sliding door, which prevents the first sliding door and the second sliding door of the sliding door assembly from moving simultaneously.

[0005] In order to solve this problem, a sliding door accessory for guiding a first sliding door and a second sliding door is proposed, which includes: a first guide element and a second guide element, the first guide element can be connected to the first sliding door, and the second guide element can be connected to the second sliding door; a guide assembly, through which the first guide element can be guided from a first closed position to a first open position, and through which the second guide element can be guided from the second closed position to the second open position, the guide assembly having a first conveying assembly, the first conveying assembly can be moved along a first movement axis from a retracted position to an extended position, wherein the first guide element is held in the first closed position in the retracted position of the first conveying assembly, and can be moved in the extended position of the first conveying assembly. The guide assembly is arranged on a guide assembly in a manner that can be moved in the direction of a first open position, and the guide assembly has a second conveying assembly, and the second conveying assembly can be moved along a second movement axis from a retracted position to an extended position, wherein the second guide element is held in a second closed position in the retracted position of the second conveying assembly, and is arranged on the guide assembly in a manner that can be moved in the direction of the second open position in the extended position of the second conveying assembly, wherein the guide assembly has a locking element, which can be movably arranged on the guide assembly by the first conveying assembly and the second conveying assembly, wherein when the second conveying assembly is arranged in the extended position, the locking element moves to a first locking position, in which the movement of the first conveying assembly along the first movement axis is locked.

[0006] An advantage of the sliding door fitting according to the present invention is that it prevents the first transport assembly and the second transport assembly from being transported into the extended position simultaneously, thereby preventing a collision of the two sliding doors.

[0007] In one possible embodiment of the sliding door fitting, the locking element is movable into a second locking position in which a movement of the second conveyor assembly along the second axis of movement is blocked when the first conveyor assembly is arranged in the extended position.

[0008] In another possible embodiment, when the first conveying assembly and the second conveying assembly are respectively arranged in the retracted position, the locking element can release the movement of the first conveying assembly along the first movement axis and the movement of the second conveying assembly along the second movement axis.

[0009] In one embodiment, the locking element can be connected to the guide arrangement in such a way that it can be pivoted about a pivot axis.

[0010] Another embodiment is conceivable, in which the first conveyor assembly can have a first locking element roller, which can rotate about a first rotation axis perpendicular to the first axis of motion. In the extended position and / or retracted position of the first conveyor assembly, the first locking element roller can be in contact with the locking element. Alternatively or in combination, the second conveyor assembly can have a second locking element roller, which can rotate about a second rotation axis perpendicular to the second axis of motion. In the extended position and / or retracted position of the second conveyor assembly, the second locking element roller can be in contact with the locking element.

[0011] The sliding door fitting can include a cam disc which is firmly connected to the guide assembly. The first locking element roller can abut against the cam disc in the retracted position and / or the extended position of the first conveying assembly. Alternatively or in combination, the second locking element roller can abut against the cam disc in the retracted position and / or the extended position of the second conveying assembly.

[0012] In another possible embodiment, the first transport assembly can have a first support element roller, which can rotate about a third rotation axis perpendicular to the first axis of motion. Here, the first support element roller can be in contact with the first support element in the extended position and / or retracted position of the first transport assembly. Alternatively or in combination, the second transport assembly can have a second support element roller, which can rotate about a fourth rotation axis perpendicular to the second axis of motion. Here, the second support element roller can be in contact with the second support element in the extended position and / or retracted position of the second transport assembly.

[0013] The first conveying assembly can include a first slider element and a first spring element. Here, the first locking element roller and the first supporting element roller are mutually supported by the first spring element. The first locking element roller and the first supporting element roller can be arranged on the first slider element movably along the spring axis of the first spring element, respectively. Here, the spring axis of the first spring element can be arranged transversely to the first axis of motion. Alternatively or in combination, the second conveying assembly includes a second slider element and a second spring element. The second locking element roller and the second supporting element roller can be mutually supported by the second spring element. The second locking element roller and the second supporting element roller can be arranged on the second slider element movably along the spring axis of the second spring element, respectively. Here, the spring axis of the second spring element is arranged transversely to the second axis of motion.

[0014] The distance between the first rotation axis and the third rotation axis can be greater in the retracted position of the first conveying assembly than in the extended position of the first conveying assembly. Therefore, the spring force of the first spring element acting on the first locking element roller can be smaller in the retracted position of the first conveying assembly than in the extended position of the first conveying assembly. Alternatively or in combination, the distance between the second rotation axis and the fourth rotation axis can be greater in the retracted position of the second conveying assembly than in the extended position of the second conveying assembly. Therefore, the spring force of the second spring element acting on the second locking element roller can be greater in the retracted position of the second conveying assembly than in the extended position of the second conveying assembly.

[0015] The spring force of the first spring element can be adjusted by a first adjusting device. In particular, the spring force of the first spring element can be adjustable by the first adjusting device in the extended position and / or the retracted position of the first conveying assembly. Alternatively or in combination, the spring force of the second spring element can be adjustable by a second adjusting device. In particular, the spring force of the second spring element can be adjustable by the second adjusting device in the extended position and / or the retracted position of the second conveying assembly.

[0016] In the plane in which the first and third rotation axes lie, the distance between the cam disc and the first support element can be greater in the retracted position of the first conveyor assembly than in the extended position of the first conveyor assembly. Alternatively or in combination, in the plane in which the second and fourth rotation axes lie, the distance between the cam disc and the second support element can be greater in the retracted position of the second conveyor assembly than in the extended position of the second conveyor assembly.

[0017] In the extended position of the first conveyor assembly, a contact force can act between the first locking element roller and the locking element, so that a swinging moment about the swing axis acts on the locking element, which loads the locking element in the direction of the second locking position. Alternatively or in combination, in the extended position of the second conveyor assembly, a contact force can act between the second locking element roller and the locking element, so that a swinging moment about the swing axis acts on the locking element, which loads the locking element in the direction of the first locking position.

[0033] Fig.15 Along Figure 6 Cross-sectional view of section XV-XV in FIG. DETAILED DESCRIPTION

[0034] Figures 1 to 15 2 shows a sliding door fitting 1 for furniture, which will be described together below. The sliding door fitting 1 has a guide assembly 5, which is configured for guiding and / or supporting a sliding door assembly.

[0035] The sliding door assembly currently comprises a first sliding door 2 and a second sliding door 2'. A first guide element 3 is rotatably fastened to the first sliding door 2 via a first support element 4. A second guide element 3' is rotatably fastened to the second sliding door 2' via a second support element 4'. The first and second guide elements are each configured as a guide roller.

[0036] The guide assembly 5 comprises a track assembly 6 having a first rail 7 and a second rail 8. The first rail 7 is arranged between the sliding doors 2, 2' and the second rail 8, so the first rail 7 is also called the front rail 7 and the second rail 8 is also called the rear rail.

[0037] The first rail 7 is configured so that the first guide element 3 can be moved from a first closed position into a first open position, and the second guide element 3' can be moved on the first rail 7 from a second closed position into a second open position. In the first closed position of the first guide element 3, the first sliding door 2 is arranged as a part of the furniture corresponding to the sliding door 2 is closed, and in the first open position of the first guide element 3, the first sliding door 2 is arranged as a part of the furniture corresponding to the first sliding door 2 is accessible. In the second closed position of the second guide element 3', the second sliding door 2' is arranged as a part of the furniture corresponding to the second sliding door 2' is closed, and in the second open position of the second guide element 3, the second sliding door 2 is arranged as a part of the furniture corresponding to the second sliding door 2' is accessible.

[0038] The second rail 8 is designed to enable a further guide element to be slidably arranged on one of the sliding doors, the further guide element being rotatably connected to the one sliding door. In the present case, the first rail 7 and the second rail 8 are designed at least in sections to be parallel.

[0039] The guide assembly 5 also includes a transport locking assembly 9, by means of which the first guide element 3 and the second guide element 3' can be transported from the retracted position to the extended position, respectively. The retracted position of the first guide element 3 is equivalent to the first closed position of the first guide element 3. The retracted position of the second guide element 3' is equivalent to the second closed position of the second guide element 3'. Therefore, the corresponding sliding doors 2, 2' corresponding to the guide elements 3, 3' are closed in the corresponding retracted positions. In the extended position, the corresponding sliding doors 2, 2' corresponding to the guide elements 3, 3' are partially opened, and the guide elements 3, 3' can be moved on the first rail 7 so that the corresponding sliding doors 2, 2' corresponding to the guide elements 3, 3' are fully opened. At present, the transport locking assembly 9 and the track assembly 6 are configured to be integrated with each other. Therefore, the guide assembly 5 can also be called a guide module.

[0040] In order to transport the first guide element 3 from the retracted position to the extended position, the transport locking assembly 9 comprises a first transport assembly 10, which can be transported from the retracted position to the extended position. In order to transport the second guide element 3' from the retracted position to the extended position, the transport locking assembly 9 comprises a second transport assembly 10', which can be transported from the retracted position to the extended position.

[0041] The first transport assembly 10 comprises a slider element 11 which can be moved along a movement axis B_11 from a retracted position into an extended position. In the present case, the movement axis B_11 of the slider element 11 is implemented linearly. For this purpose, the slider element 11 is guided on a linear guide 39. However, in principle, it is also conceivable that the movement axis B_11 of the slider element 11 has a shape that deviates from a straight line.

[0042] The partial section 12 of the first rail 7 and the partial section 13 of the second rail 8 are integrated into the slide element 11. In the retracted position of the slide element 11, the partial section 12 of the first rail 7 forms a holding section on which the first guide element 3 is held in the retracted position or in the first closed position.

[0043] In the extended position of the slider element 11, the subsection 12 of the first rail 7 is arranged such that another subsection of the first rail 7 adjoins the subsection 12 of the first rail 7, so that a continuous rail section of the first rail 7 is formed by two subsections. In the extended position of the slider element 11, the subsection 13 of the second rail 8 is arranged such that two further subsections of the second rail 8 are connected to one another via the subsection 13 of the second rail 8, so that a continuous rail section of the second rail 8 is formed by three subsections. By “continuous rail section” is to be understood that the guide element should be able to be guided on the rail, wherein a disconnection joint should be harmless.

[0044] The first conveying assembly 10 comprises a locking element roller 14, which at least partially abuts against a cam disc 34 between the retracted position and the extended position of the first conveying assembly 10'. The cam disc 34 has a first guide profile 35. When the first conveying assembly 10 is conveyed from the retracted position to the extended position, the locking element roller 14 runs on the first guide profile 35. The cam disc 34 also has a second guide profile 36. When the second conveying assembly 10' is conveyed from the retracted position to the extended position, the locking element roller 14' runs on the second guide profile 36. The cam disc 34 is connected to the guide assembly 5 via a fastening assembly 33. The fastening assembly 33 comprises one or more spacer sleeves, in the present case four spacer sleeves.

[0045] In the present case, the locking element roller 14 is permanently in contact with the cam disc 34 between the retracted position and the extended position of the first conveying assembly 10. The locking element roller 14 is supported on the slider element 11 so as to be rotatable about the rotation axis D_14. The rotation axis D_14 of the locking element roller 14 and the movement axis B_11 of the slider element 11 are arranged transversely to each other, in particular orthogonally to each other. For this purpose, the slider element 11 has a first sliding element 15, on which the locking element roller 14 is rotatably arranged. The first sliding element 15 is movably arranged in the sliding channel 16 of the slider element 11.

[0046] The first conveyor assembly 10 comprises a supporting element roller 17 which at least partially bears against a supporting element 37 between the retracted position and the extended position of the first conveyor assembly 10. The supporting element 37 has a supporting contour 38. When the first conveyor assembly 10 is conveyed from the retracted position into the extended position, the supporting element roller 17 runs on the supporting contour 38. In other words, in the present case, the supporting element roller 17 permanently bears against the supporting element 37 between the retracted position and the extended position of the first conveyor assembly 10.

[0047] The supporting element roller 17 is supported on the slider element 11 so as to be rotatable about the rotation axis D_17. The rotation axis D_17 of the locking element roller 17 and the movement axis B_11 of the slider element 11 are arranged transversely to each other, in particular orthogonally to each other. For this purpose, the slider element 11 has a second sliding element 18 on which the supporting element roller 17 is rotatably arranged. The second sliding element 18 is movably arranged in a second sliding channel 19 of the slider element 11.

[0048] The locking element roller 14 and the supporting element roller 17 are resiliently supported by a spring element 20. The spring element 20 is connected to the first sliding element 15 by means of a first end and is connected to the second sliding element 18 by means of a second end opposite to the first end. The locking element roller 14 and the supporting element roller 17 are arranged substantially movably relative to each other. The locking element roller 14 can be arranged movably along a first axis on the slider element 11, while the supporting element roller 17 can be arranged movably along a second axis on the slider element 11. The first axis and the second axis can be arranged parallel to each other or transversely to each other, and can also be identical. In the present case, the locking element roller 14 and the supporting element roller 17 are arranged on the slider element 11 in a manner that they can be moved along the spring axis F_20 of the spring element 20. Therefore, the first axis and the second axis are identical. In the present case, the rotation axis D_14 of the locking element roller 14 and the rotation axis D_17 of the supporting element roller 17 are arranged parallel to each other. The rotation axis D_14 of the locking element roller 14 and the rotation axis D_17 of the supporting element roller 17 describe a plane in which the spring axis F_20 is also arranged.

[0049] The shortest distance between the guide profile 35 of the cam disc 34 and the support profile 38 of the support element 37 varies with the position of the first transport assembly 10 or the position of the slider element 11 of the first transport assembly 10. In other words, the distance between the rotation axis D_14 of the locking element roller 14 and the rotation axis D_17 of the support element roller 17 varies with the position of the first transport assembly 10 or the position of the slider element 11 of the first transport assembly 10. By changing the distance between the rotation axis D_14 of the locking element roller 14 and the rotation axis D_17 of the support element roller 17, the spring force of the spring element 20 acting on the locking element roller 14 and the support element roller 17 varies with the position of the first transport assembly 10 or the position of the slider element 11 of the first transport assembly.

[0050] In the present case, the distance between the rotation axis D_14 of the locking element roller 14 and the rotation axis D_17 of the supporting element roller 17 is greater in the retracted position of the first conveyor assembly 10 than in the extended position of the first conveyor assembly 10. Therefore, the spring force of the spring element 20 acting on the locking element roller 14 and the supporting element roller 17 is smaller in the retracted position of the first conveyor assembly 10 than in the extended position of the first conveyor assembly 10.

[0051] The preload of the spring element 20 can be adjusted by the adjusting device 21. In other words, the spring force of the spring element 20 acting on the locking element roller 14 and the supporting element roller 17 can be adjusted by the adjusting device 21. In the present case, the adjusting device 21 is arranged on the end of the second sliding element 18. Therefore, the adjusting device 21 is in contact with the spring element 20.

[0052] The guide assembly 5, in particular the transport locking assembly 9, is now configured mirror-symmetrically with respect to the symmetry axis E_sym. Therefore, the second transport assembly 10' is arranged and configured mirror-symmetrically with respect to the first transport assembly 10, wherein the individual elements of the second transport assembly 10' are identical to the elements of the first transport assembly 10. In this respect, reference is made to the above description of the first transport assembly 10 for the description of the second transport assembly 10'. In the figures, corresponding elements are provided with the same reference numerals, wherein the elements of the second transport assembly 10' are additionally marked with an overline.

[0053] The transport locking assembly 9 has a locking element 22. The locking element 22 is supported so as to be pivotable about a pivot axis S by means of a pivot bearing 31. In the present case, the pivot axis S is located in the plane of symmetry E_sym. The locking element 22 is arranged between a cam disk 34 and the piece of furniture. The locking element 22 has recesses 32 corresponding to the number of spacer sleeves of the fastening assembly 33, through which the spacer sleeves of the fastening assembly 33 extend. The recesses 32 are configured here so that the locking element 22 does not abut against the spacer sleeves of the fastening assembly 33.

[0054] The locking element 22 can be pivoted by the first and second conveyor assembly 10 , 10 ′ about a pivot axis S. For this purpose, a force is applied to the locking element 22 by a locking element roller 14 of the first conveyor assembly 10 and a locking element roller 14 ′ of the second conveyor assembly 10 ′, respectively, depending on the position of the respective conveyor assembly 10 , 10 ′.

[0055] The locking element 22 has a first adjustment contour 23, which can be in contact with the locking element roller 14 of the first conveying component 10. The first adjustment contour 23 includes a locking section 24, with which the locking element roller 14 can be in contact if the first conveying component 10 is in the retracted position. The first adjustment contour 23 includes a retaining section 26, with which the locking element roller 14 is in contact if the first conveying component 10 is in the extended position. A conveying section 25 extends between the locking section 24 and the retaining section 26, with which the locking element roller 14 is in contact when the first conveying component 10 is conveyed from the retracted position to the extended position. The locking section 24, the conveying section 25 and the retaining section 26 can each be implemented linearly or have a shape that deviates from a straight line.

[0056] The first adjustment contour 23 has at least in sections the same course as the first guide contour 35 of the cam disk 34. The locking element 22 can therefore be pivoted so that the first adjustment contour 23 is arranged in a direction parallel to the pivot axis S, overlapping the first guide contour 35 of the cam disk 34, at least in the region of the transfer section 25 and the holding section 26.

[0057] The locking element 22 has a second adjustment contour 27, which can be in contact with the locking element roller 14' of the second conveying component 10'. The second adjustment contour 27 includes a locking section 28, and the locking element roller 14' can be in contact with the locking section if the second conveying component 10' is in the retracted position. The second adjustment contour 27 includes a retaining section 30, and the locking element roller 14' can be in contact with the retaining section if the second conveying component 10' is in the extended position. A conveying section 29 extends between the locking section 28 and the retaining section 30, and the locking element roller 14' is in contact with the conveying section when the second conveying component 10' is conveyed from the retracted position to the extended position. The locking section 28, the conveying section 29 and the retaining section 30 can be implemented linearly, respectively, or can have a shape that deviates from a straight line.

[0058] The second adjustment contour 27 has at least in sections the same course as the second guide contour 36 of the cam disk 34. The locking element 22 can therefore be pivoted such that the second adjustment contour 27 is arranged in a direction parallel to the pivot axis S, overlapping the second guide contour 36 of the cam disk 34, at least in the region of the transport section 29 and / or the holding section 30.

[0059] If the first transport assembly 10 and the second transport assembly 10' are respectively in the retracted position, for example Figure 2 , Figure 4 , Figure 8 and Fig.13 As shown in , the locking element 22 can be freely swung between the locking element roller 14 of the first conveying component 10 and the locking element roller 14' of the second conveying component 10', that is, it is arranged basically without force. In this state, the movement of the first conveying component 10 or the slider element 11 along the movement axis B_11 or the movement of the second conveying component 10' or the slider element 11' along the movement axis B_11' is released by the locking element 22. "Release of movement" should be understood here as the corresponding movement is not blocked by the locking element 22. In this case, the locking element roller 14 of the first conveying component 10 is against the first guide contour 35 of the cam disc 34, and the locking element roller 14' of the second conveying component 10' is against the second guide contour 36 of the cam disc 34. The cam disc 34 here completely receives the spring force of the corresponding spring elements 20, 20' acting on the locking element roller 14 of the first conveying component 10 and the locking element roller 14' of the second conveying component 10'.

[0060] If the first transport assembly 10 is in the extended position and the second transport assembly 10' is in the retracted position, for example Figure 3 and 6 As shown in the figure, the locking element 22 is definedly arranged between the locking element roller 14 of the first conveying component 10 and the locking element roller 14' of the second conveying component 10', wherein the spring force acting on the locking element roller 14 of the first conveying component 10 and the locking element roller 14' of the second conveying component 10' by the corresponding spring elements 20, 20' prevents the locking element 22 from swinging freely or without force.

[0061] In this case, the locking element roller 14 of the first conveyor assembly 10 bears against the retaining section 26 of the adjustment contour 23 of the locking element 22 and loads the locking element 22 with the spring force of the spring element 20. As a result, a torque about the pivot axis S is applied to the locking element 22 by the locking element roller 14 of the first conveyor assembly 10, so that the locking element 22 is driven in the direction of the second conveyor assembly 10'.

[0062] The locking element roller 14' of the second conveying assembly 10' abuts against the locking section 28 of the second adjustment contour 27 of the locking element 22 and applies the spring force of the spring element 20' to the locking element 22. As a result, a torque about the pivot axis S is applied to the locking element 22 by the locking element roller 14' of the second conveying assembly 10'. In the present case, the torque applied to the locking element 22 by the second conveying assembly 10' drives the locking element 22 in the direction of the first conveying assembly 10, wherein the torque applied to the locking element 22 by the locking element roller 14 of the first conveying assembly 10 and the torque applied to the locking element 22 by the locking element roller 14' of the second conveying assembly 10' are in a balanced state. Here, the first adjustment contour 23 of the locking element 22 and the first guide contour 35 of the cam disc 34 overlap in the region of the retaining section 26. An excessively large spring force of the spring 20 would destroy the balance between the torques and drive the locking element 20 further in the direction of the second conveying assembly 10 ′, so the spring force is received by the cam disc 34 .

[0063] Here, the line of force action of the contact force between the locking element roller 14' of the second conveyor assembly 10' and the locking section 28 of the second adjustment contour 27 of the locking element 22 intersects, for example, an imaginary connecting line of the rotation axis D_14 and the pivot axis S. In this case, the contact force between the locking element roller 14 of the first conveyor assembly 10 and the locking element 22 acts on the locking element roller 14, so that the locking element roller 14 is at least partially subjected to a force in the direction of the subsection 12 of the first rail 7. For example, the contact force between the locking element roller 14 of the first conveyor assembly 10 and the locking element 22 can have a first force component in the direction of the spring axis F_20 in the direction of the supporting element roller 17 and a second force component in the direction of the movement axis B_11, wherein the second force component is oriented in the direction of the subsection 12 of the first rail 7.

[0064] In the above case, the movement of the first conveying assembly 10 or the slider element 11 along the movement axis B_11 in the direction of the retracted position is released by the locking element 22. In this state, the movement of the second conveying assembly 10' or the slider element 11' along the movement axis B_11' is blocked by the locking element 22. Therefore, the locking element 22 is in a locked position relative to the second conveying assembly 10'.

[0065] In a first special case, if the first conveyor assembly 10 is in the extended position and the second conveyor assembly 10 ′ is in the retracted position, the line of force of the contact force between the locking element roller 14 ′ of the second conveyor assembly 10 ′ and the locking section 28 of the second adjustment contour 27 of the locking element 22 extends through the pivot axis S. In this first special case, the contact force does not exert a torque about the pivot axis S on the locking element 22 .

[0066] In the second special case, if the first conveyor assembly 10 is in the extended position and the second conveyor assembly 10' is in the retracted position, the force action line of the contact force between the locking element roller 14' of the second conveyor assembly 10' and the locking section 28 of the second adjustment contour 27 of the locking element 22 extends on the side of the pivot axis S that is opposite to the rotation axis D_14 of the locking element roller 14 of the first conveyor assembly 10. In this second special case, the torque acting on the locking element 22 by the second conveyor assembly 10' drives the locking element 22 in the direction of the second conveyor assembly 10'.

[0067] In the first special case and the second special case, the conveying locking assembly 9 must include a first return device and a second return device, wherein the first return device loads the locking element 22 in the direction of the first conveying assembly 10 and the second return device loads the locking element 22 in the direction of the second conveying assembly 10', because otherwise the locking element remains permanently in the corresponding locking position.

[0068] In the present case, the previously explained locking action of the locking element 22 on the second conveyor assembly 10' already occurs between the retracted position and the extended position of the first conveyor assembly 10. In this case, the locking element roller 14 of the first conveyor assembly 10 abuts against the transfer section 25 of the adjustment contour 23 of the locking element 22 and loads the locking element 22 with the spring force of the spring element 20. As a result, the locking element 22 is pivoted and held in the direction of the second conveyor assembly 10'.

[0069] The above Figure 3 and 6 The description is made for the case shown in the figure, wherein the first transport assembly 10 is in the extended position and the second transport assembly 10' is in the retracted position, and similarly applies to the following cases, such as Fig.11 As shown, the first transport assembly 10 is in a retracted position, while the second transport assembly 10 ′ is in an extended position.
