Description

[0001] The invention relates to an arrangement for guiding a movable furniture part, preferably a furniture door, sliding door or folding sliding door, on a fixed furniture part, preferably a furniture carcass, with the features of the preamble of claim 1. The invention further relates to a piece of furniture with such an arrangement and to a method for assembling such an arrangement.

[0002] Arrangements according to the preamble of claim 1 are already known. A disadvantage of such solutions according to the prior art is that the correct tension of the rope is very difficult or even impossible to check. If the rope is not sufficiently or is too tightly tensioned, this has a negative impact on the function of a rope-operated device. In the worst case, the rope-operated device does not function properly, which can lead to damage to a movable and / or stationary part of furniture or to the furniture itself.

[0003] The applicant's own patent application A 51103 / 2020, which is still unpublished, therefore proposes a display device for indicating the rope tension.

[0004] A disadvantage of such a solution is that an installer must keep the rope under tension throughout the entire clamping or locking process on a support. This makes installation by a single person difficult. Furthermore, the rope can constrict the hand of the person holding it under tension. WO 2021 / 003507 A1 discloses an example of an arrangement for guiding a sliding door on a furniture wall.

[0005] The object of the present invention is to avoid the disadvantages described in the prior art and to provide an improved arrangement for guiding a movable furniture part, preferably a furniture door, sliding door or folding sliding door, on a fixed furniture part, preferably a furniture carcass, a piece of furniture with at least one such arrangement and a method for assembling such an arrangement.

[0006] These problems are solved by the features of independent claims 1, 14 and 15.

[0007] According to the invention, the rope tensioning device therefore has a limiting device which prevents further tensioning of at least one rope when a predetermined rope tension is reached.

[0008] This means that the technician doesn't have to manually ensure a specific cable tension. He only needs to tension the cable, as the limiting device automatically prevents further tensioning once sufficient or predetermined cable tension is reached.

[0009] Furthermore, a piece of furniture according to the invention is provided with at least one fixed furniture part, at least one movable furniture part and at least one arrangement according to one of the preceding claims, preferably wherein the furniture has at least one shaft-shaped cavity in which the at least one movable furniture part can be arranged.

[0010] Furthermore, a method according to the invention for assembling an arrangement according to one of the preceding claims is provided, wherein In a first process step, at least one guide system is attached to the stationary furniture part; in a second process step, the support is connected to the at least one guide system in a movement-coupled manner; and in a third process step, the rope of the rope pulling device is tensioned by means of the rope tensioning device, whereby further tensioning of the rope is prevented by the limiting device when a predetermined rope tension is reached.

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

[0012] Preferably, the rope tensioning device may have an actuating element for actuating the rope tensioning device.

[0013] Particularly preferably, it may be provided that, by means of the limiting device, an effective connection between the rope tensioning device and the actuating element can be interrupted when a predetermined actuating torque is reached, preferably corresponding to the predetermined rope tension.

[0014] This provides a simple and reliable way to prevent further tensioning of the rope after a predetermined rope tension has been reached.

[0015] Advantageously, the actuating element can be incorporated into the limiting device. This allows for a more compact design of the cable tensioning device.

[0016] However, it is also conceivable that the actuating element is designed differently.

[0017] The limiting device may include a bearing element in or on which the actuating element can be stored or is stored. This embodiment also allows for a more compact design of the cable tensioning device.

[0018] Preferably, the limiting device can include a connecting element by which the bearing element and the actuating element are at least temporarily coupled or connectable in a movement-coupled manner.

[0019] Particularly preferably, the limiting device may have a force storage device by which the connecting element is or can be subjected to a predetermined force, and / or wherein the connecting element is designed at least partially as a force storage device, preferably wherein the predetermined actuating torque is defined by the force storage device and / or the connecting element designed at least partially as a force storage device.

[0020] This allows a motion-coupled connection between the bearing element and the actuating element to be realized.

[0021] It is particularly preferred that the connecting element, upon reaching the predetermined rope tension, is elastically deformable against the action of the energy storage device and / or the connecting element designed at least partially as an energy storage device, thereby enabling the release of a motion-coupled connection between the bearing element and the actuating element.

[0022] This allows the actuating element to be decoupled from the bearing element, so that further actuation of the actuating element does not result in any further tensioning of the rope.

[0023] The rope tensioning device may also include an indicator to show the rope tension status. This allows verification of whether the rope has already been tensioned or not.

[0024] Advantageously, it can be provided that a clamping element is connected or connectable to the bearing element in a movement-coupled manner.

[0025] Preferably, the display device may include a display element with an indicator. This makes it easier to implement a display device.

[0026] The rope tensioning device may include at least one locking device for securing at least one rope. This allows for straightforward securing of the rope.

[0027] According to a preferred embodiment, it can be provided that, in addition to the at least one cable pull device, at least one pivot lever mechanism is provided, wherein the at least one pivot lever mechanism comprises at least two pivot levers connected to each other by pivots, which can be pivoted relative to each other when the support is moved on the stationary part of the furniture.

[0028] With regard to a method according to the invention, it may be provided that the following additional steps are provided before the third method step: Inserting the rope into the rope tensioning device and securing the rope using the locking device.

[0029] It may also be provided that, in an intermediate step, at least one of the at least two swivel levers is connected to the at least one guide system and / or to the stationary part of the furniture.

[0030] Preferably, in a further process step, a movable furniture part, preferably a sliding door or folding sliding door, can be mounted on the support.

[0031] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings. These show: Fig. 1 a piece of furniture with an arrangement in a perspective view, Fig. 2a a part of a piece of furniture with an arrangement in a perspective view, Fig. 2b detail A of the Figure 2a Fig. 3 a partial exploded view of a rope tensioning device, Fig. 4a an exploded view of a limiting device and a tensioning unit, Fig. 4 a perspective view of a limiting device, Fig. 4c a perspective view of a bearing element and an actuating element, Fig. 4e a perspective view of a connecting element, Fig. 4e a sectional view of a limiting device, and Fig. 5a a rope tensioning device in a front view during a step of a method according to the invention.

[0032] In the Figure 1A perspective view shows a piece of furniture 100, which can include different components, for example, several compartments inside the piece of furniture 100. The fixed furniture part 3 is formed by a furniture carcass.

[0033] The piece of furniture 100 has a cavity 101, which is formed by two spaced-apart furniture walls 101a. A movable furniture part 2 in the form of a furniture door can be recessed into the cavity 101. When the furniture door is closed, it conceals the interior of the piece of furniture 100.

[0034] Adjoining furniture 100 is another part of furniture 102, for example a cabinet. If the cabinet door is in a closed position and the other part of furniture 102 is also closed, then the cabinet door and the other part of furniture 102 form a continuous furniture front.

[0035] Figure 2aFigure 1 shows a portion of a piece of furniture 100 with an arrangement 1 in a perspective view. For clarity, the second furniture wall 101a of the cavity 101 is not shown. A guide system 4 and a furniture wall 3 are visible. A support 6 is also apparent. However, another guide system or several other guide systems could also be provided here.

[0036] A movable furniture part 3 is pivotably mounted on the support 6 via hinges 6a.

[0037] A compensation device 7 consisting of a cable pull device 8 and a pivot lever mechanism 5. The pivot lever mechanism 5 consists of a first pivot lever 5a and a second pivot lever 5b. The first pivot lever 5a is attached to the stationary furniture part 3 and is slidably mounted on the support 6. The second pivot lever 5b is attached to the support 6 and is centrally located on the first pivot lever 5a.

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

[0039] The Figure 2b Detail A shows the Figure 2a The rope tensioning device 9 is visible. The rope tensioning device 9 has a housing 9c through which the rope 8a is guided.

[0040] In the lower section, part of the locking device 9a is visible, by means of which the cable 8a can be fixed to the cable tensioning device 9 and thus to the support 6. A limiting device 10 is also only partially visible.

[0041] The Figure 3 Figure 1 shows a partial exploded view of a rope tensioning device 9. A base body 9b is visible. A locking device 9a is arranged on the base body 9, which is at least partially formed by the base body 9b.

[0042] The locking device 9a comprises two clamping jaws which can be screwed together using two screws. The rope can be clamped between the clamping jaws and thus secured. However, other designs of locking devices are also conceivable, for example spring-loaded clamping elements or toothed clamping elements.

[0043] A clamping unit 12 comprises a clamping element 12b and a contact element 12a. The clamping element 12b has a movement thread, wherein the clamping element 12a is arranged on this movement thread with a corresponding thread.

[0044] The clamping element 12b is rotatably but immovably mounted on the base body 9c. A rotation of the clamping element 12b therefore results in a movement of the clamping element 12a in the axial direction of the clamping element 12b.

[0045] The limiting device 10 is connected to the clamping element 12b via a movement coupling.

[0046] A display device 13 comprising a display element 13a with an indicator 13b and a viewing window 13c is also discernible. The display element 13a is pivotably mounted on the base body 9b.

[0047] Based on the Figures 4a to 4e The function of the limiting device will be explained in more detail below. It will show Figure 4a an exploded view of a limiting device 10 and a clamping unit 12, Figure 4b a perspective view of a limiting device 10, Figure 4c a perspective view of a bearing element 10a and an actuating element 11, Figure 4d a perspective view of a connecting element 10b and Figure 4e a sectional view of a limiting device 10.

[0048] The bearing element 10a is essentially rotationally symmetrical. It is connected via a hexagonal shaft stub of the clamping element 12b and a corresponding receptacle in the bearing element 10a (see Figure 4c A motion-coupled connection can be established between bearing element 10a and clamping element 12b. Of course, any other suitable connection type is conceivable here.

[0049] The actuating element 11 is mounted in the bearing element 10a. Without the connecting element 10b, the actuating element 11 can rotate freely in the bearing element.

[0050] The connecting element 10b is essentially semicircular and has a connecting pin 10d. This connecting pin passes through the opening 10e in the bearing element 10a and rests against a control contour 11b of the actuating element 11.

[0051] The connecting element 10b is subjected to a defined force by a force storage element 10c, which is also essentially semicircular and in the form of a spring.

[0052] Thus, at least a movement-coupled connection exists between bearing element 10a and actuating element 11.

[0053] When the actuating element 11 is actuated, in this embodiment rotated, the bearing element 1a also rotates and consequently the clamping element 12b, which in turn results in a movement of the contact element 12a.

[0054] In the present embodiment, the actuating element 11 has a screw head drive 11a, which allows the actuating element 11 to be actuated via a screwdriver.

[0055] If resistance is encountered at the contact element 12a, for example because the rope is tensioned or is under tension, a higher actuating moment, in this case torque, is required at the actuating element 11 to move the contact element 12a further.

[0056] With a sufficiently high actuating torque, the actuating element 11 displaces the connecting pin 10d upwards against the force of the energy storage device 10c via the control contour 11b. The actuating element 11 begins to rotate within the bearing element 10a.

[0057] If the actuating torque is increased further, the actuating element 11 rotates continuously until the connecting pin 10d has moved out of the recess of the control profile 11b. At this point, there is no longer any coupling of movement between the bearing element 10a and the actuating element 11. Further rotation, i.e., actuation, of the actuating element 11 does not result in any further rotation of the bearing element 10a and therefore no movement of the contact element 12a, and consequently no further tensioning of the cable 8a.

[0058] The force which the energy storage device 10c opposes to a movement of the connecting pin 10d out of the opening 10e can be selected such that the connecting pin 10d passes over the elevation 11c exactly when the predetermined or desired rope tension is reached.

[0059] This makes it possible to prevent further tensioning of at least one rope 8a by means of the limiting device 10 when a predetermined rope tension is reached.

[0060] A spring element 12c, which may be designed, for example, as an O-ring, can be arranged between the contact element 12a and the clamping element 12b. The advantage of this element 12c is that it prevents the contact element 12a and the clamping element 12b from jamming in the event of incorrect actuation of the clamping element 12b.

[0061] The Figures 5a to 5c Figure 9 shows a rope tensioning device in a front view during a step of a method according to the invention.

[0062] In Figure 5aIt is evident that the rope 8a has already been passed through the rope tensioning device 9 and fixed to the base body 9b by means of the locking device 9a. The rope 8a is not yet taut, which is indicated by the fact that the contact element 12a is not yet in contact with the rope 8a.

[0063] The rope is also guided through the display element 13a, with the indicator 13b visible in the viewing window 13c. The display element 13a can, for example, be pre-tensioned by a spring, so that the indicator 13b is visible in the viewing window 13c when the rope is slack.

[0064] In Figure 5b The actuating element 5b was actuated and the contact element 12a was brought into contact with the rope 8a. It is also conceivable that this occurred via a direct rotation of the bearing surface 10a by means of the actuating section 10f.

[0065] The indicator element 13a shows that the rope 8a has already been stretched somewhat. The indicator element 13b has been pushed downwards by the rope 8a.

[0066] In the Figure 5b The rope 8a is fully taut. The display element 13a is completely pressed down and the indicator 13b is therefore no longer visible in the viewing window 13c.

[0067] This figure shows the maximum deflection of the cable tensioning device 9. The actual position of the contact element 12a is typically between the points shown in the Figures 5b and 5c The positions shown are located there.

[0068] The actual position of the contact element 12a when the predetermined rope tension is reached depends, on the one hand, on the predetermined rope tension itself. On the other hand, it is also significantly influenced by where on the rope 8a a technician fixes the rope 8a in the locking device 9a.

[0069] It is conceivable that corresponding markings are provided on rope 8a, which mark a permitted clamping area.
