Description

The invention relates to a guide device for guiding a furniture part, in particular a sliding door or folding-sliding door, comprising at least one guide rail and at least one chassis which can be connected to the furniture part and which can be moved on the at least one guide rail, wherein the at least one chassis has at least one support roller mounted about a first axis of rotation for supporting the weight of the furniture part and at least one support roller for laterally guiding the furniture part, wherein the at least one support roller is mounted so as to be rotatable about a second axis of rotation oriented transversely to the first axis of rotation.

The invention further relates to 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 device.

The invention further relates to a method for guiding at least one furniture part, in particular a sliding door or folding-sliding door, relative to a furniture body by means of at least one such guide device.

Guide devices for furniture parts, in particular sliding doors or folding-sliding doors, are already known in the state of the art. There are designs that have only one roller. In this case, this roller takes on the function of both a carrying and a supporting roller. Furthermore, designs are known that have both a carrying and a supporting roller.

Both variants are common for normal loads, i.e. conventional opening and/or closing movements. However, as soon as the load from the furniture part no longer acts exclusively in the vertical direction, but also sideways, i.e. perpendicular to the sliding direction and the vertical, the function of the support roller becomes increasingly important. This is the case with folding-sliding doors, for example. In some positions of the doors, in addition to the vertical load, a lateral force acts on the guide device, which is caused by the folded parts of the sliding door with a lateral overhang. With such lateral loads, the support roller ensures that the guide device does not become wedged or jammed by centering the support roller in the guide rail.

If a lateral force acts on the support rollers over a long period of time, this can cause the support rollers to become deformed. This means that the guide device can no longer move smoothly or the support rollers start to rattle. This type of deformation is also known as flattening and is caused by a force acting on the support rollers over a long period of time while they are not moving.

The object of the invention is to improve a guide device in such a way that flattening of the support rollers is prevented or at least reduced. It is also an object of the invention to provide a piece of furniture with an improved guide device. It is also an object of the invention to provide a method using an improved guide device.

These objects are solved by the features of claims 1, 13 and 14.

In the guide device according to the invention, it is therefore provided that at least one support device is provided which is separate from the at least one support roller and which is designed to relieve the at least one support roller in at least one end position of the at least one guide rail against a transverse force acting laterally, i.e. essentially parallel to the first axis of rotation.

By relieving the load on the support rollers in at least one end position, permanent loading of the support rollers in a position in which the furniture part often remains for a longer period of time is prevented. This can prevent or at least reduce flattening of at least one support roller and extend the service life of the guide device.

It can be provided that the at least one support device has at least a first part and a second part which are movable relative to one another, wherein the first part and the second part are coupled to one another in a first position in order to relieve the at least one support roller against the transverse force, and wherein the first part and the second part are decoupled from one another at least in a second position.

The two-part design ensures that the support roller can only be used in a certain position or in the The load is relieved in a certain position and can fulfil its design function unhindered in at least a second position. It is also possible for such a support device to be subsequently attached to a guide device.

It can be provided that one of the at least two parts of the at least one support device is connected to the at least one chassis in a movement-coupled manner, and/or wherein the other of the at least two parts of the at least one support device can be arranged in a stationary manner, preferably connected to the at least one guide rail.

Such a design can enable a more stable construction, since only one part of the support device is movable, while the second part can be arranged in a fixed position. This can reduce the likelihood of damage to the components, since the fixed component has no room for movement.

It can be provided that the at least one support device has at least one ramp, preferably wherein the at least one ramp is aligned substantially parallel to the second axis of rotation of the at least one support roller, and/or the at least one ramp is aligned obliquely to a longitudinal direction of the at least one guide rail.

Parallel means that the axis of rotation and the plane of the ramp do not have a common intersection point. The ramp is inclined to a longitudinal direction of the guide rail if it forms an acute angle with it.

The ramp can serve to guide the support device and thus simplify the unloading process of at least one support roller in an end position of the guide rail.

It can be provided that at least one support is provided which is aligned substantially parallel to the second axis of rotation and on which the furniture part can be mounted, preferably via at least one hinge, and/or at least two guide rails are provided which are arranged substantially transversely to one another.

A support, which is aligned essentially parallel to the second axis of rotation, enables the motion-coupled connection of two guide devices. This allows better and more stable guidance of the furniture part. This can prevent the furniture part from tipping over, especially when subjected to lateral loads. In addition, a support can serve as a connecting element between the individual rollers and thus also serve as a chassis.

It is also possible for the furniture part to be mounted on two guide rails that are perpendicular to each other. This makes it possible to move around corners. With a folding-sliding door, it is possible that the folding-sliding door will always be outside the space between the two guide rails when moving. In general, the use of two Guide rails increase the freedom of movement of the furniture part.

The use of a second guide rail can enable the furniture part to move in a direction transverse to the first guide rail, which can increase the lateral load on the first guide rail. This makes it even more important to relieve the load on the support roller in the end positions in order to prevent the support rollers from flattening.

It can be provided that the at least one support device has at least one rolling element, preferably wherein the at least one rolling element is mounted so as to be rotatable about a third axis of rotation aligned parallel to the second axis of rotation of the at least one support roller, and/or is mounted on the at least one chassis via at least one needle roller bearing, and/or is made of steel at least in regions.

The use of a rolling element as part of the support device can improve the relief of the support roller in an end position of the guide rail. The round shape of the rolling element can simplify coupling in an end position.

In order to ensure relief against lateral loading, it has proven advantageous if the rolling bearings are mounted so that they can rotate about an axis of rotation parallel to the second axis of rotation. Such positioning enables optimum relief of the support roller, since the rolling bearings can be aligned parallel to at least one support roller.

The use of a needle roller bearing can ensure good support for the rolling elements. At the same time, this allows a space-saving design of the rolling elements to be achieved.

In order to prevent wear and/or flattening of the rolling element, steel can be used for the rolling element, at least in some areas. However, other hard, non-brittle materials are also conceivable. The deformation of such materials is negligible even under long-term loads. This makes such materials ideal for permanently relieving the load on the support rollers.

It can be provided that the at least one support device has at least one sliding body.

A sliding body can also be used to ensure that the support rollers are relieved in an end position of the guide rail. Such a sliding body can be used as an alternative or in addition to a rolling body. The sliding body can serve as a guide for the support device during the relief process in order to gradually limit the existing range of motion of the guide device in the area of the end position and to gradually reduce the load on the support rollers in this area until the coupled position is reached.

It can be provided that contact of the at least one support roller to the at least one guide rail in the at least one end position of the at least one guide rail can be eliminated by the at least one support device. This prevents the support roller from flattening. because in this end position there is no longer any lateral load on the support roller.

It can be provided that the at least one guide rail consists at least partially of aluminum, and/or wherein a lateral surface of the at least one support roller consists of plastic, and/or wherein the at least one support device has at least one part made of steel that can be arranged in a fixed position.

Due to the low weight and relatively high strength and stability of aluminum, it can be advantageous to manufacture the guide rail from aluminum, at least in part. For good and quiet rolling behavior of the support roller, it can be advantageous if it is made of plastic. It is also conceivable that only the outer shell of the support roller is made of plastic. For the support device, it can be advantageous if at least one part of the support device that can be arranged in a fixed position is made of steel, in order to avoid wear and deformation of the support device. This can guarantee a constant relief of the support roller.

It can be provided that one of the at least two parts of the at least one support device has a U-profile which can be detachably coupled to the at least one rolling element of the second of the at least two parts of the at least one support device.

By combining a U-profile with a rolling element, the guidance of the furniture part during The U-profile serves to catch the rolling element and thereby initiate the unloading process in the end area of the guide rail and then to relieve the support roller in the coupled state. The U-profile enables relief in the event of lateral loading regardless of the direction.

According to a preferred embodiment of the guide device, it is provided that the at least one support device has at least one pin, preferably wherein the at least one pin is arranged substantially parallel to a longitudinal direction of the at least one guide rail, and/or at least a second pin is provided, wherein the two pins are spaced apart from one another, preferably in a transverse direction of the at least one guide rail, and/or the at least one pin has a ramp in an end region, and/or the at least one pin is arranged in a preferably corresponding recess of a profile section of the at least one guide rail, and/or the at least one pin consists substantially of steel, and/or the at least one pin is arranged in an end region of the at least one guide rail.

The furniture according to the invention consists of at least one furniture part, in particular a sliding door or folding-sliding door, a furniture body and at least one guide device according to the invention, preferably wherein the furniture has at least one interior space which can be covered at least in part by the at least one furniture part, in in which kitchen furniture and/or kitchen appliances can be arranged, and/or has at least one cavity extending in a depth direction of the furniture for at least partially receiving the at least one furniture part.

Such an arrangement makes it possible to use the interior of the furniture without restrictions. By partially stowing the furniture parts in the hollow spaces, the impression is created that the interior of the furniture is part of the room. This impression is also reinforced by the fact that no additional guide is required in the floor area of the furniture part. If the interior is no longer needed, the furniture can be closed and the interior is visually separated from the rest of the room.

Fig. 1a shows a perspective view of a piece of furniture 20 with a furniture body 21 and plate-shaped furniture parts 2 that can be moved relative thereto and can also be seen as a folding-sliding door. The furniture parts 2 consist of individual plate-shaped parts that are connected by Hinge fittings 28 (not shown in this figure) are connected to each other.

By means of a guide system 24, the furniture parts 2 are movably mounted on the cross rail 25 between a first position in which the furniture parts 2 are aligned essentially coplanar to one another and a second position in which the furniture parts 2 are aligned essentially parallel to one another. In the parallel position, the furniture parts 2 can be pushed in a first direction of movement M1 into a lateral cavity 23, which serves as a receiving compartment.

The functionality is described below using a furniture part 2, with the same explanations being applicable to the second furniture part 2. The guide system 24 comprises a cross rail 25 with a longitudinal direction L, with a guide carriage 26 that can be connected to the furniture part 2 being mounted so that it can move along the cross rail 24.

In Figure 2 one of the two foldable furniture parts 2 has been moved from the coplanar position to an angular position. The hinge fittings 28, which connect both furniture parts 2 to each other, are now visible.

The furniture part 2 is rotatably mounted on a support 11 via two or more hinges 27. The support 11 is mounted on at least one guide rail 3 (not shown in this figure) and can be pushed into the cavity 23 in the direction of the depth of the furniture body 21. The support 11 is designed so that in this position it connects to the cross rail 25 in the longitudinal direction L. and that the guide carriage 26 is transferable between the cross rail 25 and the carrier 11. Thus, the guide carriage 26 can be pushed onto the carrier 11 in this position.

The support 11 is designed as an elongated column whose length corresponds to at least half the height of the furniture parts 2.

Figure 2a shows the furniture 20, whereby the two furniture parts 2 are in a parallel position to each other. The guide carriage 26 has been transferred to the carrier 11. The carrier 11 has been unlocked by sliding the guide carriage 26 and is in this state along the guide rail 3 (not shown here, see Fig.3 ) can be inserted into the cavity 23 in the depth direction of the furniture body 21.

Figure 2b shows the furniture 20 with the furniture parts 2 in a completely inserted state. The furniture parts 2 are thus guided by the guide system 24 starting from a first coplanar position according to Figure 1a and a second parallel position according to Figure 2b , in which the furniture parts 2 were pushed into the cavity 23, movably mounted. The cavity 23 is formed by a side wall 14 of the furniture body 21 and an outer wall 17 of the furniture 20 arranged parallel thereto.

In this way, the interior 22 of the furniture 20, such as a kitchen or a work surface, can be completely covered so that this interior 22 can be separated from the rest of the living space.

Fig.3 shows the furniture 20, wherein the outer wall 17 has been hidden in order to illustrate the arrangement of the guide rail 3 in the cavity 23. At least one guide rail 3 for guiding the support 11 and thus the furniture part 2 is mounted on the side wall 14 of the furniture body 21.

Two guide rails 3 can be seen in the figure, which can ensure better guidance of the carrier 11. The guide rails 3 are arranged transversely, preferably at right angles, to the cross rail 25. The other components of the guide device 1 are not visible in this figure and are discussed in more detail in the following figures.

Despite the guide carriage 26, which supports part of the weight of the furniture part 2, the support 11 and thus the guide device 1 experience a strong and permanent lateral load due to the lateral deflection of the furniture part 2 in the closed state. In order to prevent the support rollers 6 from flattening at least in the closed position, a support device 7 according to the invention can be used.

Figure 4a shows the guide device 1 with support 11 in the decoupled state. For a better overview, the additional illustration of the furniture part 2 and the furniture body 21 has been omitted. On the right-hand side, the guide device 1 and the support 11 are shown in full to clarify which section is shown in which perspective. In the detailed view, the guide device 1 can be seen in the decoupled state.

The support roller 5 is movably arranged in the guide rail 3. The support roller 6 is hidden in this figure, but is located between the support roller 5 and the rolling element 12. The support roller 5 is connected to the carrier 11.

The first part 8 of the support device 7, which is connected to the chassis 4 in a movement-coupled manner, is designed as a rolling element 12 in this embodiment. The at least one rolling element 12 and the support roller 6 hidden in this figure are attached to the same carriage 18 in this embodiment. The carriage 18 is connected to the carrier 11, whereby the carrier 11 connects the support roller 6 and the support roller 5 to one another and thus functions as a chassis 4 at the same time as the two rollers.

Figure 4b shows the embodiment of Figure 4a in a different perspective. The support roller 5 is movably mounted on a support 15 in the guide rail 3. This support 15 serves to slow down, preferably prevent, the wear of the support roller 5. In addition, the support 15 can serve to reduce noise. Under the support roller 5 is the support roller 6, which is hidden in this illustration and is connected to the carrier 11 via the carriage 18. The at least one rolling element 12 is also connected to the carriage 18.

The stationary part 9 of the support device 7 is designed in this embodiment as a U-profile, in which the at least one rolling element 12 can be coupled. The ramps 10 in the area of the U-profile, which the rolling element 12 can facilitate the guidance of the at least one rolling element 12 during the unloading process and ensure a smooth transition between the uncoupled and coupled state.

Figure 5a shows the guide device 1 from the same perspective as Figure 4a . For a better overview, the carrier 11, which also serves as the chassis 4, has been omitted in this illustration. The support roller 5 is arranged so that it can move in the guide rail 3. The first part 8 of the support device 7, which is coupled in terms of movement to the chassis 4, comprises two rolling elements 12, which are arranged on the carriage 18. Analogous to the two rolling elements 12, two support rollers 6 (which are hidden or only partially visible in this illustration) are arranged on the top side of the carriage 18.

The dual design of both the support rollers 6 and the rolling elements 12 serves to provide stable guidance of the chassis 4 (not shown). This can prevent the guide device 1 from jamming or wedging due to lateral loads and/or loads acting parallel to the direction of travel.

The second part of the support device 7, which can be arranged in a fixed position, is designed in such a way that both rolling elements 12 can be accommodated in the U-profile. This prevents the carrier 11 (not shown) from tipping over in the unloading position and additional loading of the support rollers 6 (which are not visible or only partially visible) in the unloading position.

Figure 5b shows the arrangement of the Figure 5a in the side view, which in the assembly position corresponds to the front view of the furniture 20. The support roller 5, which is mounted about a first axis of rotation D1, is movably mounted on a support 15 in the guide rail 3. The support roller 6 is mounted so that it can rotate about a second axis of rotation D2 aligned transversely to the first axis of rotation D1. The rolling elements 12 are mounted on the same carriage 18 as the support rollers 6.

Due to this arrangement, the movement of the rolling elements 12 through the carriage 18 is coupled to the chassis 4 (not shown). The support roller 5 and the support rollers 6 can be connected to a carrier 11 (not shown), which in this embodiment would simultaneously fulfill the function of the chassis 4.

The stationary part 9 of the support device 7 is designed as a U-profile, which has ramps 10 on both sides in the longitudinal direction of the guide rail 3. These ramps 10 make it easier to accommodate the rolling elements 12 in the U-profile and thus ensure a smooth transition from an uncoupled position to the coupled position.

Figure 6a shows the guide device 1 with carrier 11 in the coupled state. The arrangement is shown in full on the right-hand side in order to be able to better assign the detailed representation.

In the coupled state, the U-profile of the stationary part 9 of the support device 7 has the rolling elements 12 of the part 8 of the support device 7 which is coupled in motion to the chassis 4. Support device 7 is taken up and the support rollers 6 (not visible or hidden in this figure) are thereby relieved.

The support rollers 6 and the rolling elements 12 are arranged on the same carriage 18, which in turn is connected to the carrier 11. Since the support roller 5 is also connected to the carrier 11, in this embodiment the latter represents part of the chassis 4.

Figure 6b shows the guide device 1 with support 11 in coupled position in a side view, which corresponds to the front view of the furniture 1 in the assembly position. Although the Figure 6b compared to Figure 5b depicts the coupled state of the support device 7, no difference can be seen in this perspective.

The support roller 5 is movably mounted on a support 15 in the guide rail 3. The support roller 5 is connected to the carrier 11, on which the furniture part 2 can be rotatably mounted. The support roller 6 and the rolling elements 12 are arranged on the same carriage 18, which is also connected to the carrier 11.

Figure 7 shows a second embodiment of a support device 7 according to the invention in the coupled state. The guide rail 3 is mounted on the side wall 14 of the furniture body 21. The first part 8 of the support device 7, which is coupled in motion to the chassis 4, is arranged on the carrier 11. The stationary part 9 of the support device 7 is arranged on the guide rail 3.

However, the chassis 4 or the at least one support roller 6 and the support roller 4 are hidden in this figure by the carrier 11. On the first part 8 of the support device 7, for use according to the Figures 1a, 1b , 2a and 2b An attachment with a holder for the guide carriage 26 of the cross rail 25 can also be arranged. In order to ensure a transfer from the cross rail 25 to this attachment, a recess is provided on the side wall 14.

Figure 8 shows the embodiment of Figure 7 in an exploded view. The guide device 1 consists of a guide rail 3, a carrier 11 with a chassis 4 arranged thereon, which comprises at least one support roller 5 and at least one support roller 6. Only one support roller 6 is shown in this illustration. The second support roller 6 and the support roller 5 are covered by the carrier 11.

The support device 7 consists of two parts, wherein the first part 8 of the support device 7 can be arranged in a movement-coupled manner with the chassis 4 and the second part 9 of the support device 7 can be arranged in a stationary manner.

The first part 8 of the support device 7, which can be coupled to the chassis 4, has a sliding body 13, which serves as a guide during the initiation and/or relief process. The second part 9 of the support device 7, which can be arranged in a fixed position, can be arranged on the guide rail 3 and connected to it with a screw 16. The corresponding counterpart with a thread for receiving the screw 16 is covered by the second part 9 of the support device 7 in this illustration.

Figure 9 shows a horizontal section of the embodiment of Figure 7 in the decoupled state. Two support rollers 6 are movably arranged in the guide rail 3. These are connected by the chassis 4 to the support roller 5 which is covered by the chassis 4.

The first ramp 10 of the first part 8 of the support device 7, which is arranged in a motion-coupled manner with the chassis 4, as seen from the end of the guide rail 3 shown, serves to guide the motion-coupled part 8 of the support device 7 during the coupling process. The second ramp 10 serves to bring the first part 8 of the guide device 7 into the correct end position and thereby ensure permanent relief of the support rollers 6 in the end position.

Figure 10 shows the same horizontal section as Figure 9 in the coupled state. The first part 8 of the support device 7, which is coupled in motion to the chassis 4, is in the end position and is flush with the second part 9 of the support device 7, which can be arranged in a fixed position.

In this position, when used in accordance with the Figures 1a, 1b , 2a, and 2b the furniture part 2 can be moved from the parallel position to the coplanar position in order to cover the interior 22 of the furniture 20. This leads to a change in the load on the guide device 1 and thus on the support device 7. This change in load causes the two parts 8, 9 of the support device 1 to wedge into one another, which relieves the load on the support rollers 6. is additionally reinforced and the chassis 4 is fixed in the final position.

Fig. 11a-11e show various views of a bearing device 19 for the rotatable mounting of the rolling element 12 and/or the support roller 6. The bearing device 19 comprises a, preferably plate-shaped, base part 19a and a bearing pin 29 for mounting the rolling element 12 and/or the support roller 6. The bearing device 19 shown can in particular increase the tilting stability of the bearing pin 29, the rolling element 12 and the support roller 6 in relation to the base part 19a.

Fig. 11a shows a perspective view of the bearing device 19, Fig. 11b shows the bearing device 19 in a side view, Fig. 11c shows a plan view of the bearing device 19, Fig. 11d shows a sectional view along the plane AA according to Fig. 11c and Fig. 11e shows the Fig. 11d circled area in an enlarged view.

As can be seen from the sectional view according to Fig. 11d As can be seen, the rolling element 12 and the support roller 6 are spaced apart from one another in a vertical direction. The compact needle roller bearing 30 for the rotatable mounting of the rolling element 12 can be seen.
