Guide assembly for sliding doors and cupboard unit

[0037] The cabinet unit 1 includes a furniture main body 2 provided with sliding doors 3, 4, 5 and 6 on the front side of the furniture main body 2, and the sliding doors 3, 4, 5 and 6 cover the top plate 16 of the furniture main body 2 in the front. A cover 17 is also installed on the top plate 16, which has a shorter depth than the top plate 16.

[0038] in figure 2 In the middle, the outer sliding doors 3 and 6 have been slightly opened so that the interior space 7 of the furniture body 2 is partially accessible. The outer sliding doors 3 and 6 can move independently, and can move in the plane behind the middle sliding doors 4 and 5.

[0039] in image 3 In this, the middle sliding doors 4 and 5 have each moved outward in opposite directions so that the internal space 7 located at the rear and further divided by the main body center wall 2a can be accessed for use. For the correspondingly more rigid design of the furniture main body 2 and for the suitable internal structure of the cabinet unit 1, the main body central wall 2a can also be omitted. The sliding doors 4 and 5 are movable in front of the outer sliding doors 3 and 6 in this case, and are connected together by a control cable so that the sliding doors 4 and 5 move in opposite directions, respectively.

[0040] in Figure 4 In, the cabinet unit 1 is shown, there is no cover 17 on the top plate 16, and it can be seen that the middle sliding doors 4 and 5 are movably held on the guide rail 13 by the middle guide parts 8 and 9, and the middle guide parts 8 and 9 Designed as a sliding part. in Figure 4 Here, only one guide part 8 or 9 is shown for each sliding door 4 or 5, but at least two guide parts are provided to movably hold the sliding door 4 or 5 on the guide rail 13. However, only the association between the adjacently arranged guide portions 8 and 9 and the movement of the sliding doors 4 and 5 is relevant and is therefore described in more detail. Above the top side of the top plate 16, the control cable 10 is tensioned, fixed to the guide parts 8 and 9, and then guided on opposite sides by deflection rollers 11 and 12 arranged in the area of ​​the outer sliding doors 3 and 6. The guiding parts 8 and 9 are forcibly guided by the control cable 10.

[0041] in Figure 5 In the figure, a guide part 9 fixed to the sliding door 5 is shown, and the middle sliding door 5 is held on the guide rail 13 by the guide part 9. The guide portion 9 has rollers 27 guided in the rear guide rail 14 of the guide rail 13. In the adjacent front guide rail 15, the rollers of the guide portions (not shown here) of the outer sliding doors 3 and 6 are movably held. The rear guide rail 14 is used to guide the middle sliding doors 4 and 5. The guide rail 13 has a web 19 protruding forward, and the anti-lift mechanism 18 on the guide portion 9 is engaged below the web 19 so that the guide portion 9 is fixed to prevent the guide portion 9 from being lifted and moved from the guide rail 13 except. In this case, the guide rail 13 is fixed to the top plate 16 of the furniture body 2 through its angled section. The sliding doors 3, 4, 5 and 6 thus cover the front edge of the top plate 16 so that the guide rail 13 is only visible in the open position.

[0042] A gasket 26 is arranged on the top plate 16, and the plate-shaped cover 17 is supported on the gasket 26. The cover 17 is joined above the top sides of the sliding doors 3, 4, 5, and 6 with a certain gap so that the guide portions 8, 9 extending above the top sides of the rear sliding doors 3, 6 pass through, so that the front sliding door 4 During the displacement of, 5, the guiding parts 8, 9 do not collide with the rear sliding doors 3, 6.

[0043] On the top board 16, a deflection roller 12 for deflecting the control cable 10 is rotatably mounted on a shaft whose orientation is perpendicular to the sliding direction of the sliding door and perpendicular to the top side of the top board 16. The control cable 10 is fixed to the guide part 9 by a holder 30.

[0044] The device for synchronizing the movement of the intermediate sliding doors 4 and 5 is in Image 6 It is shown in a bottom view in which the guide rail 13 and the top plate 16 are not shown for the purpose of clarity of illustration. The control cable 10 includes a first section, the first section has a ring 22 that engages around a bolt 21, and is then guided around the deflection roller 11, and then fixed on the holder 30 by a fastening device 31 at its end, wherein the The bolt 21 is arranged on the holder 20, which is fixed to the guide part 8 by screws 25 on its underside, and the holder 30 is fixed to the guide part 9 by screws 25. The second section of the control cable is fixed to the holder 30 of the guide part 9 by another fastening device 31 at one end, then is guided around the deflection roller 12 and fixed to the holder 20 by another bolt 21 at one end. Therefore, both ends of the control cable are fixed to the same guide portion 8 or 9, respectively, so the control cable 10 is guided in a loop. When the bolts 21 and the fastening device 31 are symmetrically arranged and the guide portions 8 and 9 are fixed to the sliding doors 4 and 5, respectively, so that each guide portion has the same distance from the side edges of the door, two equal lengths can be used The control cable does not require additional cable guide elements and can be easily installed. It is also possible to use a single continuous control cable 10 instead of two cable sections, in which case, for example, strands arranged close to the sliding doors 4, 5 can be fixed on the holder 20 by friction.

[0045] in Image 6 The guide sections 8 and 9 are shown from below, while Figure 7 The guide portions 8 and 9 are shown in an obliquely upward perspective, and the top bottom plate 16 is also shown. The holder 20 is fixed to the guide part 8, on the underside of the guide part 8 two bolts 21 are arranged, which are surrounded by the corresponding ring 22 of the control cable 10. Each ring 22 is fixed by a clamping element 23, so that the control cable 10 is fixed on the holder 20, but cannot be adjusted.

[0046] A holder 30 is fixed on the other guide part 9, and the holder 30 includes a fastening device 31 that can adjust the tension of the control cable 10. Both ends of the control cable 10 are fixed to the holder 30 by a fastening device 31 and a tensioning device. In this case, the fastening device 31 is arranged in another vertical plane parallel to the guide rail 13, and is also arranged in a different horizontal plane parallel to the guide rail 13 with respect to the ring 22 on the guide part 8, in which the control cable 10 into a ring. As a result, the strands arranged close to the sliding doors 4, 5 can be guided to pass under the holder 30 without contact, and the other strands away from the sliding door can also be guided to pass through the holder 20 without contacting. The terms "horizontal" and "vertical" refer to the exemplary embodiment shown, and can of course be modified in the guidance of the vertically movable sliding door.

[0047] in Figure 8A with Figure 8B , The guide parts 8 and 9 are provided without the control cable 10. The holder 30 is fixed to the guide part 9 and the fastening device 31 is held on the guide part 9 to tension the control cable 10. The bolt 21 is provided on the bottom of the holder 20 for fixing the ring 22.

[0048] Such as Picture 9 As shown, the holders 20 and 30 have the same basic shape and are made of stamped and stepped metal plates. The holders 20 and 30 are recessed in a U-shape, respectively, wherein the two legs of the holders 20, 30 are fixed to the top sides of the middle legs of the curved guide portions 8 and 9 by screws 25 or rivets or other fastening devices . The anti-lift mechanism 18 is slidably held on the guide portions 8 and 9 between the legs of the U-shaped holders 20 and 30.

[0049] It is understood that the holders 20, 30 can also be used, for example, by material bonding (especially gluing or welding), by positive locking, by interlocking, or by a combination thereof, especially by embossing technology. Or clamping to the sliding parts 8, 9 in various ways. It is also conceivable to make the holders 20, 30 of plastic, which holders 20, 30 can then be fixed preferably by clamping on the sliding parts 8, 9.

[0050] Two openings 24 are provided on the holder 20 for inserting a part of the bolt 21 so that the bolt 21 protrudes on the bottom or top side of the holder 20 and can fix the control cable 10.

[0051] The fastening device 31 is fixed to the holder 30, which is fixed by a screw 32. Alternatively, it is conceivable that the fastening device 31 is fixed by being clamped on the holder 30 without tools, and for this purpose, the screws 32 are not required, as shown in FIGS. 13 and 14.

[0052] in Figure 10A to Figure 10E The installation of the holder 30 and the fastening device 31 is shown in detail. The retainer 30 has two mirror-symmetrically formed grooves 34 on the side facing away from the guide portion 9, and each groove 34 is designed with a mirror-symmetric semicircular undercut along the direction of the symmetry plane. The corresponding protrusion 37 of the fastening device 31 can be inserted into the semicircular undercut. The two fastening devices 31 for fixing one end of the control cable 10 are mirror-symmetrical, so the same reference numerals have been used. Each fastening device 31 includes a receiving portion 35 into which the web-shaped section 33 of the holder 30 can be inserted. Openings for screwing in the screws 32 are formed on the web-shaped section 33 and the receiving portion 35, respectively. The fastening device 31 is inserted into the semicircular undercut through the protrusion 37, and then the receiving part 35 is sleeved on the section 33 by pivoting, wherein the lug on the protrusion 37 is engaged on the top side of the holder 30 , And the edge is joined to the bottom surface of the holder 30. Therefore, the fastening device 31 is installed in the plane of the holder to be pivotable around the undercut portion of the groove 34, and the screw 32 is only used to fix the position. If the web-shaped portion 33 pivots into the receiving portion 35, the protrusion 37 stays in the groove 34 and the stop portion 36 firmly abuts on the section 33 of the holder 30. If the force of the control cable now acts on the outside, due to the effect of the eccentric force generated on the sleeve 38, the undercut portion and the stop portion 36 arranged in the direction of the plane of symmetry prevent the pivoting of the fastening device 31, making the tightening The fixing device is fixed to the holder 30 in a self-locking manner. The fastening device 31 also includes a sleeve 38 having a slot 39 for the insertion of the control cable 10.

[0053] in Figure 11A with Figure 11B The installation of the control cable on the holder 30 is shown in Figure 11A Shows the assembled state. First, the fastening device 31 is fixed to the holder 30 by the screw 32. Then, the control cable 10 is inserted into the sleeve 38 through the slot 39 of the sleeve 38 on the fastening device 31. The control cable 10 is fixed to the clamping element 40 and can be opposed to the sleeve by the adjusting element 41 or the spring. The barrel 38 moves to tension the control cable 10. Other adjustment mechanisms can also be used. Then, on the opposite side, the fastening device 31 is fixed to the holder 30 and the clamping element 40 and the adjustment element 41 are supported on the sleeve 38.

[0054] Figure 11C with Figure 11D Another exemplary embodiment of an assembly with an improved fastening device 31" that can also be installed is shown. The fastening device 31" differs from the first exemplary embodiment only in the covering surface above the protrusion 37 , So that the groove 34 is covered after assembly. As mentioned above, the fastening device 31" can therefore also be mounted on the holder 30.

[0055] in Picture 12 Shown in the state is fully assembled on the holder 30, in which it can be recognized that under the tensile load on the control cable 10, the undercut portion and the stop portion 36 ensure that the fastening device 31 cannot pivot around the axis of the screw 32 turn. In addition, it is shown that a sleeve 42 with a smaller diameter is arranged on the clamping element 40, wherein the adjustment element 41 is sleeved on the sleeve 42, and the sleeve 42 can be inserted into the sleeve 38 to The control cable 10 is fixed to the fastening device 31. In order to fix the fastening device 31, a locking device may be further formed on the protrusion 37, and the locking device cooperates with the groove 34 on the holder 30 to provide the fastening device 31 with a holding force at this time. Under the action of the force of the control cable 10, the fastening device 31 therefore independently bears the force, and the screw 32 only serves as a fastening device in an unloaded state to a large extent.

[0056] Figure 13A with Figure 13B A modified embodiment of the holders 20' and 30' that can be fixed to the guide portions 8 and 9 is shown. A retaining element 21' having a protrusion is fixed to the holder 20' on a groove 34', wherein a loop 22 of one end of the control cable 10 is arranged around the protrusion. Thereby, the end of the control cable 10 is fixed to the holder 20', wherein both ends are fixed to the holder 20' in each case.

[0057] The fastening device 31 ′ is fixed to the improved holder 30 ′, and the fastening device 31 ′ is fixed in the groove 34. The fastening device 31' has a sleeve 38 with a slot 39 for the control cable 10 to pass through, as is the case in the previous exemplary embodiment. The control cable 10 is fixed to the sleeve-shaped section 38 by a clamping element 40 and an adjusting element 41. However, the fastening device 31 is not additionally fixed by screws, but can be fixed by clamping and/or latching on the groove 34' on the holder 30', wherein the locking lug on the holder 30' is protruding 37’ behind the profile, this can be Figure 14B See in the section view. The holding element 21' on the holder 20' is also fixed by being clamped and/or locked into the groove 34' of the holder 20'.

[0058] Figure 15 An improved device for synchronizing the movement of the intermediate sliding doors 4 and 5 is shown. The guide portion 8 is provided with a holder 20'" for fixing the control cable 10, and on the holder 20'", the two end sections of the control cable 10 are fixed on the holding element 21"' through corresponding rings 22. Each ring 22 is fixed by a clamping element 23. A retainer 30'" is provided on the other guide portion 9. The retainer 30'" has two sleeves 31'" integrally formed, each sleeve 31' "Both are used to support the tensioning device used to fix the control cable 10. Each tensioning device includes a clamping element 40 fixed to the control cable 10 and an elastic adjustment element 41, especially supported on the sleeve 31"' Spring.

[0059] in Figure 16 with Figure 17A to Figure 17C In the detailed drawing, two holders 20"' and 30"' without guiding parts 8 and 9 are shown. Two free cuts are provided on the holder 20"', each free cut faces the integrally formed holding element 21"' for the ring 22. In order to fix one end of the control cable 10, the ring 22 is guided in each case around a holding element 21"', which is located in the plane of the plate-shaped holder 20"', so that there is a particularly flat structure. Such as Figure 17C As shown, at least at the contact edge with the ring 22, the holding element 21"' is chamfered or rounded to avoid damage to the control cable 10. The holding element 21"' and the ring 22 are arranged differently in this case In the vertical plane, but basically in the same horizontal plane as the sleeve 31"', so that the control cable 10 is guided in a loop shape in plan view.

[0060] In the illustrated embodiment, the guide assembly is used to guide the intermediate sliding doors 4 and 5 on the cabinet unit 1. Instead of the cabinet unit 1 with four doors, it is also possible to provide guide assemblies for more than four doors. In addition, the guide assembly can also be applied to the atrial septum or the intermediate wall. In addition, the guide assembly can be used to guide vertical sliding doors on furniture or room partitions.
