Abstract
Description
[0001] Arrangement for guiding a movable furniture part
[0002] 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 body, with the features of the preamble of claim 1. The invention further relates to a piece of furniture with such an arrangement and a method for assembling such an arrangement.
[0003] Arrangements according to the preamble of claim 1 are already known. A disadvantage of such prior art solutions is that the correct tension of the cable is very difficult or even impossible to check. If the cable is not sufficiently tensioned or is too tightly tensioned, this has a negative impact on the function of a cable pulling device. In the worst case, the cable pulling device does not function properly, which can lead to damage to a movable and / or fixed part of the furniture or to damage to the furniture itself.
[0004] The applicant's own patent application A 51103 / 2020, which has not yet been published, therefore proposes a display device for indicating the rope tension.
[0005] The disadvantage of this solution is that a technician must keep the rope under tension throughout the entire clamping or securing process. This makes installation by a single person difficult. Furthermore, the rope can constrict the hand of the person holding the rope under tension.
[0006] The object of the present invention is to avoid the disadvantages described according to the prior art and to provide an arrangement which is improved compared to the prior art 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.
[0007] These objects are achieved by the features of independent claims 1 , 24 and 25 .
[0008] According to the invention, it is therefore provided that the cable tensioning device has a limiting device by means of which further tensioning of the at least one cable can be prevented when a predetermined cable tension is reached.
[0009] This eliminates the need for the installer to ensure a specific rope tension is maintained. They simply need to tighten the rope, as the limiting device automatically prevents further tensioning when the rope tension is sufficient or at a predetermined level.
[0010] 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 piece of furniture has at least one shaft-shaped cavity in which the at least one movable furniture part can be arranged.
[0011] In addition, a method according to the invention for assembling an arrangement according to one of the preceding claims is provided, wherein in a first method step the at least one guide system is fastened to the fixed furniture part, in a second method step the support is connected to the at least one guide system in a movement-coupled manner, and in a third method step the cable of the cable pulling device is tensioned by means of the cable tensioning device, wherein upon reaching a predetermined cable tension further tensioning of the cable is prevented by the limiting device.
[0012] Further advantageous embodiments of the invention are defined in the dependent claims.
[0013] Preferably, it can be provided that the cable tensioning device has an actuating element for actuating the cable tensioning device.
[0014] Particularly preferably, it can be provided that an operative connection between the cable tensioning device and the actuating element can be interrupted by the limiting device when a predetermined actuating torque, preferably correlating with the predetermined cable tension, is reached.
[0015] This represents a simple and reliable way of preventing further tensioning of the rope after a predetermined rope tension has been reached.
[0016] Advantageously, the actuating element can be provided as part of the limiting device. This benefits the compact design of the cable tensioning device.
[0017] However, it is also conceivable for the actuating element to be designed differently. The limiting device can be provided with a bearing element in or on which the actuating element can be mounted or is mounted. This embodiment also enables a more compact design of the cable tensioning device.
[0018] Preferably, the limiting device may comprise a connecting element by which the bearing element and the actuating element are or can be connected in a movement-coupled manner at least temporarily.
[0019] Particularly preferably, it can be provided that the limiting device has a force accumulator by means of which the connecting element is or can be subjected to a predetermined force, and / or wherein the connecting element is designed as a force accumulator at least in some areas, preferably wherein the predetermined actuating torque is defined by the force accumulator and / or the connecting element designed as a force accumulator at least in some areas.
[0020] This enables a motion-coupled connection between the bearing element and the actuating element to be realized.
[0021] Particularly preferably, it can be provided that the connecting element is elastically deformable when the predetermined cable tension is reached against the action of the energy accumulator and / or the connecting element designed at least in regions as an energy accumulator, whereby a movement-coupled connection between the bearing element and actuating element can be canceled.
[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 further tensioning of the cable. The cable tensioning device can also be provided with an indicator to indicate the cable tension status. This allows checking whether the cable has already been tensioned or not.
[0023] Preferably, the display device may comprise a display element with an indicator. This allows for a simple implementation of a display device.
[0024] The cable tensioning device may include at least one locking device for securing the at least one cable. This allows for uncomplicated securing of the cable.
[0025] According to a preferred embodiment, it can be provided that in addition to the at least one cable pulling device, at least one pivoting lever mechanism is provided, wherein the at least one pivoting lever mechanism comprises at least two pivoting levers which are connected to one another in an articulated manner and which can be pivoted relative to one another when the carrier on the fixed furniture part moves.
[0026] With regard to a method according to the invention, it can be provided that the following additional steps are provided before the third method step:
[0027] Insert the rope into the rope tensioning device and secure the rope using the locking device.
[0028] It can also be provided that, in an intermediate step, at least one of the at least two pivot levers is connected to the at least one guide system and / or to the fixed furniture part. Preferably, in a further method step, a movable furniture part, preferably a sliding door or folding sliding door, can be mounted on the support.
[0029] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings.

[0040] Fig. 5a-c a cable tensioning device in a front view during a step of a method according to the invention.
[0041] Figure 1 shows a perspective view of a piece of furniture 100, which may comprise various components, for example, several compartments inside the piece of furniture 100. The fixed furniture part 3 is formed by a furniture carcass. The piece of furniture 100 has a cavity 101, which is formed from two spaced-apart furniture walls 101a. A movable furniture part 2 in the form of a furniture door can be lowered into the cavity 101. When the furniture door is closed, it conceals the interior of the piece of furniture 100.
[0042] Adjacent to the furniture 100 is another part of the furniture 102, for example, a cupboard. If the furniture door is in a 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 continuous furniture front.
[0043] Figure 2a shows a perspective view of part of a piece of furniture 100 with an arrangement 1. 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 visible. However, one or more additional guide systems may also be provided here.
[0044] A movable furniture part 3 is pivotally mounted on the support 6 via hinges 6a
[0045] A compensation device 7 comprising 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 arranged on the fixed furniture part 3 and is displaceably mounted on the support 6. The second pivot lever 5b is arranged on the support 6 and centrally on the first pivot lever 5a.
[0046] 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.
[0047] Figure 2b shows detail A of Figure 2a. The cable tensioning device 9 is visible. The cable tensioning device 9 has a housing 9c through which the cable 8a is guided.
[0048] In the lower area, a 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.
[0049] Figure 3 shows a partially exploded view of a cable tensioning device 9. A base body 9b is visible. A locking device 9a is arranged on the base body 9 and is formed at least partially by the base body 9b.
[0050] The locking device 9a comprises two clamping jaws that can be screwed together using two screws. The rope can be clamped between the clamping jaws and thus secured. However, other locking device designs are also conceivable, for example, spring-loaded clamping elements or toothed clamping elements.
[0051] A clamping unit 12 comprises a clamping element 12b and a contact element 12a. The clamping element 12b has a movement thread, with the clamping element 12a being arranged on this movement thread with a corresponding thread. The clamping element 12b is rotatably but immovably mounted on the base body 9c. 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.
[0052] The limiting device 10 is connected in a movement-coupled manner to the tensioning element 12b.
[0053] A display device 13 comprising a display element 13a with an indicator 13b and a viewing window 13c is also visible. The display element 13a is pivotally mounted on the base body 9b.
[0054] The function of the limiting device is explained in more detail below with reference to Figures 4a to 4e. Figure 4a shows an exploded view of a limiting device 10 and a clamping unit 12, Figure 4b shows a perspective view of a limiting device 10, Figure 4c shows a perspective view of a bearing element 10a and an actuating element 11, Figure 4d shows a perspective view of a connecting element 10b, and Figure 4e shows a sectional view of a limiting device 10.
[0055] The bearing element 10a is essentially rotationally symmetrical. A motion-coupled connection between the bearing element 10a and the clamping element 12b can be established via a hexagonal shaft stub of the clamping element 12b and a corresponding receptacle in the bearing element 10a (see Figure 4c). Of course, any other suitable connection type is conceivable.
[0056] 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. The connecting element 10b is essentially partially circular in shape and has a connecting pin 10d. This connecting pin extends through the opening 10e in the bearing element 10a and bears against a control contour 11b of the actuating element 11.
[0057] The connecting element 10b is subjected to a defined force by a force accumulator 10c in the form of a spring, which is also essentially partially circular.
[0058] Thus, an at least temporarily movement-coupled connection is provided between the bearing element 10a and the actuating element 11.
[0059] If the actuating element 11 is actuated, in this embodiment rotated, the bearing element 1a and consequently the clamping element 12b also rotate, which in turn results in a movement of the contact element 12a.
[0060] In the present embodiment, the actuating element 11 has a screw head drive 11a, whereby the actuating element 11 can be actuated via a screwdriver.
[0061] If resistance is encountered at the contact element 12a, for example because the cable is or is under tension, a higher actuating moment, in this case torque, is required at the actuating element 11 in order to move the contact element 12a further.
[0062] With a sufficiently high actuation torque, the
[0063] Actuating element 11 via the control contour 11b the
[0064] Connecting pin 10d moves upwards against the action of the energy accumulator 10c. The actuating element 11 begins to rotate within the bearing element 10a.
[0065] If the actuating torque is further increased, the actuating element 11 continues to rotate until the connecting pin 10d has moved out of the recess of the control profile 11b. At this point, there is no longer any movement coupling 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.
[0066] The force which the energy accumulator 10c opposes to a movement of the connecting pin l Od out of the opening l Oe can be selected so that the connecting pin l Od passes over the elevation 11c exactly when the predetermined or desired cable tension is reached.
[0067] This makes it possible for the limiting device 10 to prevent further tensioning of the at least one cable 8a when a predetermined cable tension is reached.
[0068] A resilient element 12c, which may be configured, 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 jamming of the contact element 12a and the clamping element 12b in the event of incorrect operation of the clamping element 12b.
[0069] Figures 5a to 5c show a front view of a cable tensioning device 9 during a step of a method according to the invention. Figure 5a shows that the cable 8a has already been passed through the cable tensioning device 9 and secured to the base body 9b by means of the locking device 9a.
[0070] 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.
[0071] The cable is also guided through the indicator element 13a, whereby the indicator 13b is visible in the viewing window 13c. The indicator element 13a can be pre-tensioned, for example, by a spring, so that the indicator 13b in the untensioned
[0072] Condition of the rope is visible in the viewing window 13c.
[0073] In Figure 5b, the actuating element 5b was actuated, and the contact element 12a was brought into contact with the cable 8a. It is also conceivable that this was achieved by directly twisting the bearing element 10a by means of the actuating section 10t.
[0074] The indicator element 13a shows that the cable 8a has already been slightly tensioned. The indicator element 13b has been pressed downward by the cable 8a.
[0075] In Figure 5b, the cable 8a is fully taut. The display element 13a is completely pressed downward, and the indicator 13b is therefore no longer visible in the viewing window 13c.
[0076] This figure shows the maximum deflection of the cable tensioning device 9. The actual position of the contact element 12a will generally lie between the positions shown in Figures 5b and 5c.
[0077] The actual position of the contact element 12a when the predetermined cable tension is reached depends, on the one hand, on the predetermined cable tension itself. On the other hand, it is also significantly influenced by the point on the cable 8a at which a technician secures the cable 8a in the locking device 9a. It is conceivable that corresponding markings are provided on the cable 8a to indicate a permissible clamping range.
