Description

Technical Field

[0001] The present invention relates to a device for guiding a movable furniture part, preferably a furniture door, a sliding door or a folding sliding door, having the features of the generic concept of claim 1, in a fixed furniture part, preferably a furniture cabinet. The present invention further relates to furniture provided with such a device, and to a method of assembling such a device.

[0002] Devices of the type described in the generic concept of claim 1 are already known. The disadvantage of such a solution according to the prior art is that it is extremely difficult or impossible to check the correct tension of the cable. If the cable is insufficiently or overly tensioned, this has an undesirable effect on the function of the cable traction device. In the worst case, the cable traction device does not function correctly, which can lead to damage to the movable and / or fixed furniture parts or the furniture.

[0003] Therefore, according to the specification of patent application A51103 / 2020 by the applicant himself, which has not yet been published, a display device for displaying the cable tension has been proposed.

[0004] The disadvantage of such a solution is that during the entire process of clamping or fixing the cable to the support, the installer has to hold the cable under tension. This makes assembly by one person difficult. Furthermore, the cable can pinch the hand of the person holding it under tension.

[0005] The object of the present invention is to avoid the above-mentioned disadvantages of the prior art and to provide a device for guiding a movable furniture part, preferably a furniture door, a sliding door or a folding sliding door, in a fixed furniture part, preferably a furniture cabinet, which is improved over the prior art, furniture provided with at least one such device, and a method of assembling such a device.

[0006] This problem is solved by the features described in independent claims 1, 24, and 25.

[0007] Therefore, according to the present invention, the cable tensioning device is assumed to have a limiting device that can prevent further tensioning of at least one cable when a preset cable tension is reached.

[0008] This eliminates the need for installers to personally ensure that the specified cable tension is maintained. Under sufficient or preset cable tension, the limiting device automatically prevents further tensioning of the cable, so the installer only needs to maintain tension on the cable.

[0009] Furthermore, the furniture according to the present invention comprises at least one fixed furniture part, at least one movable furniture part, and at least one device according to any one of claims 1 to 23, wherein the furniture preferably has at least one shaft-shaped hollow chamber into which at least one movable furniture part can be placed.

[0010] Furthermore, a method according to the present invention for assembling the apparatus described in any one of claims 1 to 23, -In the first method step, at least one guide system is attached to a fixed piece of furniture, -In the second method step, connect the support to at least one guide system to transmit motion, and further -In the third method step, the cable of the cable pulling device is tensioned by the cable tensioning device, and in this case, if a preset cable tension is reached, further tensioning of the cable is prevented by the limiting device. A method has been established.

[0011] Further advantageous embodiments of the present invention are provided in the dependent claims.

[0012] Preferably, the cable tensioning device may be assumed to have an operating element for operating the cable tensioning device.

[0013] In this case, it is particularly preferable that the limiting device can disconnect the action coupling between the cable tensioning device and the operating element when a preset operating moment, preferably associated with a preset cable tension, is reached.

[0014] This is a simple and reliable method to prevent further tensioning of the cable once a predetermined cable tension has been reached.

[0015] Advantageously, the operating element may be assumed to be part of the limiting device. This is advantageous for a compact cable tensioning device.

[0016] However, it is also possible that the operating elements are composed in other forms.

[0017] The limiting device may be assumed to have a bearing element, and the operating element may be supported or supported within or on the bearing element. Such embodiments also enable a more compact configuration of the cable tensioning device.

[0018] Preferably, the limiting device may have a coupling element, by which the bearing element and the operating element are coupled or can be coupled at least temporarily in a motion-transmission manner.

[0019] Particularly preferably, the limiting device has an accumulator, by which the coupling element is loaded or can be loaded by a preset force, and / or the coupling element is formed as an accumulator in at least a predetermined area, and preferably, a preset operating moment is defined by the accumulator and / or by the coupling element formed as an accumulator in at least a predetermined area.

[0020] This makes it possible to achieve a motion transmission coupling between the bearing element and the operating element.

[0021] Particularly preferably, the coupling element is elastically deformable against the action of the energy accumulator and / or against the action of the coupling element formed as an energy accumulator in a predetermined area when a preset cable tension is reached, thereby allowing the motion transmission coupling between the bearing element and the operating element to be released.

[0022] This allows the operating element to be separated from the bearing element, so that further operation of the operating element does not result in further tension on the cable.

[0023] It is also conceivable that the cable tensioning device has a display device for indicating the tension status of the cable. This allows for checking whether or not the cable has already been tensioned.

[0024] Preferably, the display device may be assumed to have a display element equipped with an indicator. This allows for a simple implementation of the display device.

[0025] The cable tensioning device may be assumed to have at least one fastening device for securing at least one cable. This allows for simple cable fastening.

[0026] According to a preferred embodiment, in addition to at least one cable traction device, at least one swivel lever mechanism is additionally provided, and this at least one swivel lever mechanism includes at least two swivel levers pivotally connected to each other, and these swivel levers may be assumed to be pivotable relative to each other when the support moves along the fixed furniture part.

[0027] Regarding the method according to the invention, additionally, the following steps, namely, - inserting the cable into the cable tensioning device, and - fixing the cable by means of a fixing device may be assumed to be provided before the third method step.

[0028] In an intermediate step, it may also be assumed that at least one of the at least two swivel levers is connected to at least one guide system and / or to the fixed furniture part.

[0029] Preferably, in a further method step, the movable furniture part, preferably a sliding door or a folding sliding door, can be assembled to the support.

[0030] Further details and advantages of the invention will be explained in more detail below with reference to the drawings based on the description of the drawings.

[Figure 2a] It is a perspective view showing a part of the furniture equipped with the device. <{ [Figure 2b] It is a view showing detail A of FIG. 2a. [Figure 3] It is a partial exploded view of the cable tensioning device. [Figure 4a] It is an exploded view of the limiting device and the tensioning unit. [Figure 4b]This is a perspective view of the limiting device. [Figure 4c] This is a perspective view of the bearing element and the operating element. [Figure 4d] This is a perspective view of the connecting element. [Figure 4e] This is a cross-sectional view of the limiting device. [Figure 5a] This is a front view showing a cable tensioning device during the method steps according to the present invention. [Figure 5b] This is a front view showing a cable tensioning device during the method steps according to the present invention. [Figure 5c] This is a front view showing a cable tensioning device during the method steps according to the present invention.

[0032] Figure 1 shows a perspective view of furniture 100, which can have various components, for example, multiple partition shelves inside furniture 100. The fixed furniture section 3 is formed by a furniture cabinet.

[0033] The furniture 100 has a hollow chamber 101, which is formed from two furniture walls 101a that are spaced apart from each other. A movable furniture part 2 in the form of a furniture door can be inserted into the hollow chamber 101. When the furniture door is closed, it shields the interior of the furniture 100.

[0034] Furniture 100 has another part of it 102, such as a shelf, connected to it. When the furniture door is in the closed position and the other part of the furniture 102 is also closed, the furniture door and the other part of the furniture 102 form a consistent front surface of the furniture.

[0035] Figure 2a shows a perspective view of part of the furniture 100 equipped with the device 1. For ease of understanding, the second furniture wall 101a of the hollow chamber 101 is not shown. The guide system 4 and the furniture wall 3 are recognizable. The support 6 is also visible. However, in this case, one or more other guide systems may be provided.

[0036] The movable furniture section 3 is supported on the support 6 so as to be rotatable via a hinge 6a.

[0037] The compensation device 7 consists of a cable pulling device 8 and a swivel lever mechanism 5. The swivel lever mechanism 5 consists of a first swivel lever 5a and a second swivel lever 5b. The first swivel lever 5a is located on a fixed furniture part 3 and is slidably mounted on a support 6. The second swivel lever 5b is located on the support 6 and is positioned in the middle of the first swivel lever 5a.

[0038] The cable pulling device 8 includes a cable 8a and a deflection roller 8b, which are positioned on the furniture wall 101a and / or the guide system 4. The cable tensioning device 9 is positioned on the support 6.

[0039] Figure 2b shows a detailed view A of Figure 2a. A cable tensioning device 9 is visible. The cable tensioning device 9 has a casing 9c through which the cable 8a is guided.

[0040] The lower region shows part of the fixing device 9a, which can secure the cable 8a to the cable tensioning device 9 and, consequently, to the support 6. The limiting device 10 is also shown only in part.

[0041] Figure 3 shows a partially exploded view of the cable tensioning device 9. The base 9b can be seen. A fixing device 9a, at least partially formed by the base 9b, is arranged on the base 9b.

[0042] The fastening device 9a has two clamp jaws, which can be screw-fastened to each other via two screws. The cable can be clamped and thus secured between the clamp jaws. However, other configurations of the fastening device are also possible, such as a spring-loaded clamp element or a clamp element with a toothed row.

[0043] The tension unit 12 includes a tension element 12b and a contact element 12a. In this case, the tension element 12b has a movable thread, and the corresponding thread of the clamp element 12a is positioned along this movable thread.

[0044] The tension element 12b is supported on the base 9b so as to be rotatable but not slidable. Therefore, as a result of the rotation of the tension element 12b, the clamp element 12a moves in the axial direction of the tension element 12b.

[0045] The limiting device 10 is coupled to the tension element 12b in a motion-transmission manner.

[0046] A display device 13 is also shown, which includes a display element 13a with an indicator 13b and a viewing window 13c. In this case, the display element 13a is rotatably supported on a base 9b.

[0047] The functions of the limiting device will be explained in detail below with reference to Figures 4a to 4e. In this case, Figure 4a shows an exploded view of the limiting device 10 and the tension unit 12, Figure 4b shows a perspective view of the limiting device 10, Figure 4c shows a perspective view of the bearing element 10a and the operating element 11, Figure 4d shows a perspective view of the coupling element 10b, and Figure 4e shows a cross-sectional view of the limiting device 10.

[0048] The bearing element 10a is formed substantially rotationally symmetrically. A motion-transmitting coupling can be formed between the bearing element 10a and the tension element 12b via the hexagonal shaft end of the tension element 12b and the corresponding receiving portion provided on the bearing element 10a (see Figure 4c). In this case, of course, various other appropriate coupling forms can be considered.

[0049] The operating element 11 is supported by the bearing element 10a. Without the coupling element 10b, the operating element 11 can rotate freely on the bearing element.

[0050] The coupling element 10b is substantially formed in a partial circular shape and has a coupling pin 10d. This coupling pin passes through an opening 10e provided in the bearing element 10a and contacts the control contour 11b of the operating element 11.

[0051] A force defined by the accumulator 10c, which is also substantially a partially circular spring, is applied to the coupling element 10b.

[0052] This creates at least a temporary motion-transmission coupling between the bearing element 10a and the operating element 11.

[0053] When the operating element 11 is operated, and in this embodiment rotated, the bearing element 10a also rotates, which in turn causes the tensioning element 12b to rotate, which further results in the motion of the contact element 12a.

[0054] In this embodiment, the operating element 11 has a screw head drive unit 11a, which allows the operating element 11 to be operated via a screwdriver.

[0055] For example, if tension is applied to or is applied to the cable, causing resistance in the contact element 12a, a higher operating moment, in this case torque, is required in the operating element 11 to move the contact element 12a further.

[0056] When the operating moment is sufficiently high, the operating element 11 causes the coupling pin 10d to slide upward through the control contour 11b against the action of the accumulator 10c. The operating element 11 then begins to rotate inside the bearing element 10a.

[0057] As the operating moment is further increased, the operating element 11 rotates further until the connecting pin 10d moves out of the recess in the control molded body 11b. Now there is no longer any motion transmission between the bearing element 10a and the operating element 11. Further rotation, i.e., operation, of the operating element 11 does not cause further rotation of the bearing element 10a, and therefore no motion occurs in the contact element 12a, and therefore no further tension occurs in the cable 8a.

[0058] The force exerted by the power accumulator 10c against the movement of the coupling pin 10d out of the opening 10e can be selected so that the coupling pin 10d overcomes the raised portion 11c precisely when it reaches a preset or desired cable tension.

[0059] This allows the limiting device 10 to prevent at least one cable 8a from being further tensioned when it reaches a preset cable tension.

[0060] A spring-like element 12c, which can be formed as an O-ring, for example, can be placed between the contact element 12a and the tension element 12b. The advantage of this element 12c is that it can prevent the contact element 12a and the tension element 12b from getting stuck together in the event of misoperation of the tension element 12b.

[0061] Figures 5a to 5c are front views showing the cable tensioning device 9 during the method steps according to the present invention.

[0062] In Figure 5a, it can be seen that the cable 8a is already guided through the cable tensioning device 9 and fixed to the base 9b by the fixing device 9a. In this case, the cable 8a is not yet tensioned, which is indicated by the fact that the contact element 12a is not yet in contact with the cable 8a.

[0063] The cable is further guided through the display element 13a, in which case the indicator 13b can be seen in the viewing window 13c. The display element 13a can be preloaded, for example, via a spring, so that the indicator 13b can be seen in the viewing window 13c when the cable is not tensioned.

[0064] In Figure 5b, the operating element 5b is operated, causing the contact element 12a to come into contact with the cable 8a. It is also conceivable that this contact could be achieved by directly rotating the bearing element 10a using the operating section 10f.

[0065] The indicator element 13a shows that the cable 8a is already almost taut. That is, the indicator element 13b is being pushed downward by the cable 8a.

[0066] In Figure 5b, cable 8a is fully tensioned. Display element 13a is pushed completely downward, and therefore indicator 13b is no longer visible inside the viewing window 13c.

[0067] This figure shows the maximum displacement of the cable tensioning device 9. The actual position of the contact element 12a is typically between the position shown in Figure 5b and the position shown in Figure 5c.

[0068] The actual position of the contact element 12a when the preset cable tension is reached depends, on the one hand, on the preset cable tension itself. On the other hand, this position is also greatly influenced by at what point on the cable 8a the installer secures the cable 8a within the fixing device 9a.

[0069] It is conceivable to provide appropriate markings on cable 8a to indicate the permissible clamping range.
