Description

[0001] Guide device for guiding a furniture part

[0002] The invention relates to a guide device according to the preamble of claim 1, a guide arrangement comprising at least one guide rail and at least one such guide device, a piece of furniture with at least one furniture part, in particular a sliding door or folding sliding door, a furniture body and at least one such guide arrangement, and finally a method for mounting at least one furniture part, in particular a sliding door or folding sliding door, on at least one such guide arrangement.

[0003] Guide devices according to the preamble of claim 1 are known from AT 521 140. In order to connect the connecting device to the chassis, it must be lifted against the weight of the furniture component and pivoted about an axis of rotation. This is particularly inconvenient for an installer when dealing with very heavy furniture components.

[0004] The object of the present invention is to provide a guide device that is improved compared to the prior art, avoids the disadvantages of the prior art, and is characterized in particular by simplified assembly. A further object is to provide a guide arrangement with such an improved guide device, a piece of furniture with a guide arrangement comprising such an improved guide device, and a method for assembling at least one piece of furniture onto at least one such guide arrangement.

[0005] These problems are solved by the features of claims 1, 11, 12 and 13.

[0006] In the guide device according to the invention, the at least one fastening device comprises at least one locking element, which is rotatably and slidably mounted, preferably transversely to a fastening direction of the at least one connecting device and the at least one chassis, on the at least one connecting device or on the at least one chassis. The rotatable and simultaneously slidable mounting of the locking element prevents the furniture component from being lifted and pivoted when connecting the connecting device and the chassis. Instead, the connection can be achieved by a purely translational movement of the connecting device or of the furniture component connected or connectable to it.

[0007] Advantageous embodiments of the invention are defined in claims 2 to 10 and 14 to 16.

[0008] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings. These show:

[0016] Fig. 8a), b) shows a second pivot position of a guide device in a connected state, wherein part a) shows a perspective view and part b) shows a cross-sectional view from above along the section plane 64 (see Fig. 7a)).

[0017] Figures 1a) to 1d) show an exemplary piece of furniture 35 with two furniture parts 2 in the form of folding-sliding doors, in which the present invention can be used. Instead of folding-sliding doors, other furniture parts 2, such as folding or sliding doors or flaps that open vertically, can also be used.

[0018] The furniture 35 comprises a furniture body 3 and a guide arrangement 34, which is described in detail in connection with Figure 2.

[0019] In the illustrated case, the furniture 35 has an interior 36 which can be partially covered by the furniture parts 2, in which kitchen furniture 37, 38, for example in the form of base cabinets 38 or wall cabinets 37, and kitchen appliances, such as a refrigerator or a dishwasher, can be arranged.

[0020] The furniture 35 has two recesses 40 extending in a depth direction 39 of the furniture 35 for at least partially receiving a furniture part 2 each. In Figure 1 d), the furniture parts 2 protrude slightly from the recesses 40. However, the furniture 35 can also be configured such that the furniture parts 40 can be completely recessed into the recesses 40.

[0021] Figures 1a) to 1d) show different positions of the furniture parts 2 relative to the furniture carcass 3: In sub-figure 1a), the folding sliding doors are arranged in a coplanar closed position. In sub-figure 1b), one of the doors is arranged in an open position. In sub-figure 1c), the doors are arranged in a parallel position outside the furniture carcass 3, and in sub-figure 1d), they are arranged in a parallel position within recesses 40 of the furniture carcass 3. As in the illustrated case, the furniture parts 2 can each have two surface elements 41, 42 that are articulated together, e.g., via hinges 54.

[0022] The furniture 35 can have a vertical support on which one of the surface elements 41, 42 is arranged. The vertical support can be guided along side walls 69 via guides in the depth direction 39 so as to be movable.

[0023] The furniture parts 2 can each be connected to a guide device 4 or a guide arrangement 34 via a connecting device 1, as in the case shown.

[0024] Figure 2 shows an embodiment of a guide arrangement 34.

[0025] The guide arrangement 34 comprises guide rails 16, 17 and at least one guide device 4 for guiding a furniture part 2 along the guide rails 16, 17. In the illustrated case, the guide arrangement 34 comprises two guide rails 16, 17, which are arranged essentially transversely to each other.

[0026] The guide device 4 comprises a carriage 18 with rotatably mounted rolling elements 19, 20, by means of which the carriage 18 can be slidably mounted on raceways 21, 22, 23 of the guide rail 16. The rolling elements 19 are rotatably mounted about a substantially vertical axis and function as lateral support rollers. The rolling elements 20 are rotatably mounted about a substantially horizontal axis and function as carrying rollers.

[0027] The guide device 4 further comprises a connecting device 1, designed as a hinge in the case shown, for connecting the guide device 4 to the furniture part 2.

[0028] The chassis 18 and the connecting device 1 are designed as separate components and can be detachably connected to each other via a fastening device 24. The fastening device 24 comprises a locking element 25, which is rotatably and slidably mounted on the chassis 18, in the illustrated case transversely to a fastening direction 26 of the connecting device 1 and the chassis 18. The locking element 25 can also be rotatably and slidably mounted on the connecting device 1. More than one locking element 25 can also be provided, which are rotatably and slidably mounted on the connecting device 1 and / or on the chassis 18.

[0029] Figures 3a) and 3b) show the guide device 4 in a disconnected state.

[0030] The chassis 18 has a base 28, wherein the locking element 25 is rotatably and slidably mounted on the base 28. In the illustrated case, this is technically achieved by a pivot axis 44 slidably mounted in an elongated hole 43.

[0031] The locking element 25 is designed as a pivot plate.

[0032] The locking element 25 is connected to the base 28 via springs 27, specifically tension springs, the springs 27 being connected to the locking element 25 and the base 28 in such a way that the springs 27 can be tensioned when the connecting device 1 and the chassis 18 are connected (see also Figures 6a) to 6d)). In the illustrated case, the springs 27 are attached to the base 28 via spring hangers 63 (see also Figure 5b)).

[0033] The technical background of the springs 27 is as follows: When the folding-sliding doors are arranged in the coplanar and parallel positions, they are in a relatively stable state due to the rigidity of the fittings connecting them to the furniture 35. The situation is different when the folding-sliding doors are arranged in an intermediate position between these two maximum positions: In this case, the weight force 65 can cause the folding-sliding doors to sag 66, which is greatest in the area of ​​the hinged connection of the door leaves (see Figure 1b)). This sagging can have negative consequences: Due to the angle 67-dependent sagging 66, wear and tear can occur on the fittings connecting the folding-sliding doors to the furniture 35.Furthermore, the lowering 66 can even lead to the folding sliding doors grazing the surface in an intermediate position, which can result in jamming of the folding sliding doors and / or wear of the folding sliding doors in the lower area.

[0034] One way to counteract this sagging 66 is to make the fitting components as stable as possible. However, this is only possible to a limited extent. Furthermore, this approach would result in a very high material requirement, particularly for the design of the guide rail(s) used, which in turn is associated with high costs.

[0035] In the present case, a different approach is pursued, which consists of the chassis 18 comprising a force storage device in the form of two springs 27, by which the furniture part 2 can be subjected to a force opposing the weight force 65 in the operating state. This measure makes it possible to counteract the lowering 66 of the furniture part 2 in an intermediate position between the coplanar and parallel positions. This allows the lowering 66 to be limited to a tolerable amount, at which the described disadvantages can be largely avoided. It is advantageous for the force storage device to be designed to provide a predetermined maximum force, preferably between 50 N and 150 N.

[0036] The fastening device 25, by means of which the connecting device 1 and the chassis 18 can be connected to each other, comprises a locking contour 29 and a locking bolt 30 that can be locked in or on the locking contour 29. In the illustrated case, the locking contour 29 is arranged on the chassis 18 and the locking bolt 30 on the connecting device 1. Equally, the locking contour 29 can also be arranged on the connecting device 1 and the locking bolt 30 on the chassis 18. The locking bolt 30 is subjected to a spring force by a spring element 45, e.g., designed as a compression spring (see, e.g., Figure 4b).

[0037] As can be seen particularly from Figure 6a), the locking contour 29 has an inclined surface 48 arranged at an angle 46 of 7°–15°, particularly preferably 11°, relative to a longitudinal extension 47 of the locking element 25. This angle 46 causes the locking bolt 30 to self-lock, whereby the spring force of the spring element 45 is in principle no longer required in the locked position (see Figure 6d)) to securely hold the locking bolt 30 in the locking contour 29.

[0038] A mounting device 31 is also provided, via which the connecting device 1 can be mounted on the chassis 18. Specifically, the mounting device 31 can be implemented, as in the illustrated case, by comprising a mounting contour 32 and a mounting bolt 33 that can be mounted into the mounting contour 32. The mounting contour 32 can be arranged on the connecting device 1 and the mounting bolt 33 on the chassis 18, or vice versa.

[0039] As can be seen in particular from Figures 4a) and 4b), the suspension device 31 can have two suspension points 49 as in the illustrated embodiment, via which the connecting device 1 can be suspended on the chassis 18.

[0040] As in the illustrated case, an assembly aid 50 can be provided, which ensures that the assembly can be hooked onto the hook points 49. The assembly aid 50 can, for example, be made of plastic and / or be attached to the connecting device 1 by means of a positive locking 60 and rivet 61 (see also Figure 4b)).

[0041] Figures 4a) and 4b) show the connecting device 1 in detail.

[0042] In the illustrated embodiment, the connecting device 1 is designed as a hinge and comprises two components 6, 7 that are pivotable relative to each other via a joint mechanism 5. One of the two components 6, 7 can be connected to the furniture part 2, and the other component 6, 7 can be connected to the furniture body 3 or the guide device 4. Specifically, component 6 has fastening means 55 in the form of holes in which, for example, screws can be inserted. Component 7 can be connected to the chassis 18 of the guide device 4 via the fastening device 24 already described.

[0043] The joint mechanism 5 has four joint axes 12, 13, 14, 15, which, as in the illustrated case, can be designed, for example, as pivot rivets.

[0044] The connecting device 1 has a magnetic device 8 with which the two components 6, 7 can be detachably fixed in a pivot position (see Figures 7a) and 7b)). In this pivot position, in which they can be detachably fixed, the two components 6, 7 are essentially parallel to each other.

[0045] The magnetic device 8 has a magnet 9 and a counterpart 10 which can be connected to the magnet 9 and which consists of a material that is attracted to the magnet 9, wherein the magnet 9 can be designed as a permanent magnet as in the case shown and the counterpart 10 can be essentially flat.

[0046] The magnetic device 8 is partially integrated into the joint mechanism 5, wherein the joint mechanism 5 has an intermediate lever 11 and at least one component of the magnetic device 8, specifically the magnet 9, is arranged on the intermediate lever 11. The intermediate lever 11 has a recess 56 into which the magnet 9 is inserted via a holder 57.

[0047] The joint mechanism 5 has a further intermediate lever 59.

[0048] At least one further component of the magnetic device 8, specifically the counterpart 10, which can be connected to the magnet 9 and consists of a material attracted to the magnet 9, is arranged on one of the two components 6, 7 that can be pivoted relative to each other; in the illustrated case, on the component 6 that can be connected to the furniture part 2. The connecting device 1 has a slider 58, which can, for example, be made partially or entirely of plastic. The slider 58 has an opening 70 for receiving the spring element 45. The locking bolt 30 is also inserted into the slider 58.

[0049] The slider 58 is slidably mounted on the connecting device 1 in a displacement direction 68 (see Figure 3a).

[0050] The chassis 18 is shown in detail in Figures 5a) and 5b).

[0051] In addition to the components already described, the chassis 18 can, as in the case shown, have a rolling element carrier 62 on which the rolling elements 19, 20 are rotatably mounted.

[0052] Figures 6a) to 6d) show a sequence of steps in connecting a connecting device 1 and a chassis 18. The sub-figures show different sectional planes to make the relevant components of the guide device 4 visible.

[0053] This sequence of steps can be embedded in a procedure for mounting a furniture part 2 on a guide arrangement 34, comprising the following procedure steps:

[0054] - Mounting the connecting device 1 on the furniture part 2, and

[0055] - Connecting the connecting device 1 and the chassis 18, which is slidably mounted on the raceways 21, 22, 23 of the guide rail 16, via the fastening device 24, wherein the locking element 25 of the fastening device 24 is rotated and, in the illustrated case, moved transversely to a fastening direction 26 of the connecting device 1 and the chassis 18.

[0056] A mounting device 31 is provided. The connecting device 1 is attached to the chassis 18 via the mounting device 31 before being connected to the chassis 18 (see Figure 6a). Subsequently, the connecting device 1 and the furniture part 2 connected to it are moved in the fastening direction 26 towards the chassis 18. During this movement, the distance 53 between the connecting device 1 and the chassis 18 decreases, as can be seen particularly from a comparison of Figures 6a) to 6c).

[0057] The connecting device 1 is now connected to the chassis 18 via the fastening device 24 (see Figures 6b) and 6c)). The locking bolt 30 encounters a deflecting contour 71. This causes the slider 58 to move upwards against the spring force of the spring element 45, compressing the spring element 45 in the process. After overcoming a maximum 72, the locking bolt 30 slides into the locking contour 29 under the action of the spring element 45.

[0058] The locking element 25 is connected to the base 28 of the chassis 18 via springs 27. When the connecting device 1 and the chassis 18 are connected, the springs 27 are automatically tensioned.

[0059] Figure 6d) shows the locked position or state of the guide device 4 in which the connecting device 1 is connected to the chassis 18.

[0060] The spring force of the spring element 45 causes the locking bolt 30 to rest against the locking contour 29 of the locking element 25.

[0061] The chassis 18 has two support surfaces 52, which, in addition to the fastening device 24, secure the connecting device 1 against loosening of the connection between the chassis 18 and the connecting device 1, such as in the event of an upward lift for any reason. In this case, the support surfaces 52, against which the pivot axis 44 rests, prevent the connecting device 1 from disengaging.

[0062] It is nevertheless possible to intentionally disconnect the chassis 18 from the connecting device 1. For this purpose, a release element 51 is provided, which can be actuated by a screwdriver and moved against the spring force of the spring element 45. To release the connection, the release element 51, which, as in the illustrated case, can be a pressure piece formed on the slide 58, is pressed from bottom to top with the screwdriver. This moves the locking bolt 30 out of the locking contour 29. If a slight pulling force is simultaneously applied to the furniture part 2, the connecting device 1 lifts off the chassis 18.

[0063] The chassis 18 and the connecting device 1 are pivotable relative to each other about a pivot axis 44 when connected. This allows the furniture part 2 to tilt towards the interior 36, thus preventing excessive stress on the rolling elements 19.

[0064] As already explained, the connecting device 1 comprises a magnetic device 8 with which the two components 6, 7, which are pivotable relative to each other, can be detachably fixed in a pivot position. This is illustrated in Figures 7a) and 7b). The pivot position corresponds to the coplanar relative position of the two

[0065] Surface elements 41, 42 of furniture part 2. This means that through the

[0066] Magnetic device 8 keeps the furniture part 2 in the closed position.

[0067] Figures 8a) and 8b) show a different pivot position of the guide device 4, in which the magnetic device 1 is deactivated, and in which the two components 6, 7 are freely movable relative to each other via the

[0068] Joint mechanism 5 are pivotable.
