Description

Technical Field

[0001] The invention relates to a guiding device for guiding a furniture component.

[0002] The invention also relates to a piece of furniture having at least one furniture part, in particular a sliding door or a folding sliding door, a furniture carcass and at least one such guide device.

[0003] The invention also relates to a method for guiding at least one furniture component, in particular a sliding door or a folding sliding door, relative to a furniture carcass by means of at least one such guide device. Background Art

[0004] Guide devices for furniture parts, in particular for sliding doors or folding sliding doors, are known in the prior art. There are embodiments with only one roller. In this case, this roller assumes the function of a load-bearing roller and a support roller. In addition, embodiments are known that have both a load-bearing roller and a support roller.

[0005] Under normal loads, i.e. conventional opening and / or closing movements, both variants are common. The function of the support rollers becomes increasingly important as soon as the loads from the furniture component no longer act only in the vertical direction, but also laterally, i.e. perpendicularly to the sliding direction and the vertical. This is the case, for example, with folding sliding doors. In certain positions of the door, in addition to the vertical loads, there are also lateral forces acting on the guide device, which are caused by the folded part of the sliding door with its lateral overhang. Under such lateral loads, the support rollers ensure that the guide device does not become wedged or jammed by centering the load-bearing rollers in the guide rails.

[0006] If lateral forces act continuously on the support rollers, the support rollers may deform. This means that the guide device can no longer move evenly or the support rollers rattle. This deformation is also called squeezing and is caused by continuous forces acting on the support rollers when they are not moving. Summary of the invention

[0007] The present invention aims to improve a guide device in order to prevent or at least reduce the crushing of the support rollers. In addition, the present invention aims to provide a piece of furniture with the improved guide device. In addition, the present invention aims to provide a method of using the improved guide device.

[0008] This object is achieved by the features of the following claims.

[0009] 14. The invention relates to a guide device for guiding a furniture component, in particular a sliding door or a folding sliding door, comprising: at least one guide rail and at least one movable mechanism that can be connected to the furniture component, the at least one movable mechanism being able to move on the at least one guide rail, wherein the at least one movable mechanism has at least one load-bearing roller and at least one support roller, the at least one load-bearing roller being mounted about a first rotation axis and being used to support the weight of the furniture component, the at least one support roller being used to guide the furniture component laterally, wherein the at least one support roller being mounted rotatably about a second rotation axis that is oriented transversely to the first rotation axis, wherein at least one supporting device that is separate from the at least one support roller is provided, the at least one supporting device being formed such that: at at least one end position of the at least one guide rail The cam is configured to unload the lateral force acting laterally on the at least one supporting roller, that is, the lateral force acting substantially parallel to the first rotation axis, wherein the at least one supporting device has a second part and at least a first part, the second part and the at least one first part are movable relative to each other and coupled to each other in a first position to unload the lateral force acting on the at least one supporting roller, and are decoupled from each other at least in a second position, the at least one supporting device has at least one rolling body, the at least one rolling body is rotatably mounted around a third rotation axis, the third rotation axis is oriented parallel to the second rotation axis of the at least one supporting roller, and the first part or the second part of the at least one supporting device has a U-shaped profile, which can be detachably coupled to the at least one rolling body of the first part of the at least one supporting device. The furniture according to the invention comprises: at least one furniture component, in particular a sliding door or a folding sliding door; a furniture body; and at least one guide device according to the invention, preferably the furniture has at least one interior space, which can be at least partially covered by the at least one furniture component, in which kitchen furniture and / or kitchen utensils can be arranged, and / or the furniture has at least one empty chamber extending in the depth direction of the furniture, which is used to at least partially accommodate the at least one furniture component.The method according to the invention for guiding at least one furniture component, in particular a sliding door or a folding sliding door, relative to a furniture body by means of at least one guiding device according to the invention is characterized in that the method comprises the following steps: supporting the weight of the at least one furniture component by the at least one supporting roller of the at least one moving mechanism; guiding the furniture component laterally by the at least one supporting roller when the furniture component moves along the at least one guide rail; and relieving the at least one supporting roller of laterally acting transverse forces, i.e. transverse forces acting essentially parallel to the first rotation axis of the at least one supporting roller, at at least one end position of the at least one guide rail by means of the at least one supporting device.

[0010] By unloading the support roller in at least one end position, the support roller is protected from continuous loading in positions where the furniture component often stops for a longer period of time. This prevents or at least reduces the crushing of at least one support roller and prolongs the service life of the guide device.

[0011] It can be arranged as follows: the at least one supporting device has at least one first part and a second part, the first part and the second part can move relative to each other, wherein the first part and the second part are coupled to each other at a first position to unload the lateral force exerted on the at least one supporting roller, and wherein the first part and the second part are decoupled from each other at least at a second position.

[0012] The two-part design ensures that the support roller is unloaded only in a specific position or in a specific position region and can fulfil its design purpose unhindered in at least one second position. It is thus also possible to subsequently attach such a support device to a guide device.

[0013] It can be provided as follows: the at least one first part of the at least one supporting device is connected to the at least one moving mechanism in a kinematically coupled manner, and / or the second part of the at least one supporting device can be provided in a fixed position, preferably connected to the at least one guide rail.

[0014] This structure can achieve a more stable construction, because only one part of the support device can move, while the second part can be arranged in a fixed position. Since the part that can be arranged in a fixed position has no room for movement, the possibility of damaging the part can be reduced.

[0015] It can be provided that the at least one supporting device has at least one ramp, preferably wherein: the at least one ramp is oriented substantially parallel to the second rotation axis of the at least one supporting roller and / or the at least one ramp is oriented inclined relative to the longitudinal direction of the at least one guide rail.

[0016] Here, parallel means that the rotation axis and the plane of the ramp have no common intersection point.The ramp is inclined relative to the longitudinal direction of the guide rail when the ramp forms an acute angle with the longitudinal direction of the guide rail.

[0017] The ramp can be used to guide the supporting device and thus simplify the unloading process of the at least one supporting roller in the end position of the guide rail.

[0018] It can be provided that at least one carrier is provided which is oriented essentially parallel to the second rotation axis, on which the furniture part can preferably be mounted via at least one hinge, and / or at least two guide rails are provided which are arranged essentially transversely to each other.

[0019] The carrier, which is oriented substantially parallel to the second axis of rotation, enables a kinematically coupled connection of the two guide devices. This allows a better and more stable guidance of the furniture component. This prevents the furniture component from tilting, in particular when subjected to lateral loads. Furthermore, the carrier can serve as a connecting element between the individual rollers and thus simultaneously as a moving mechanism.

[0020] The furniture component can also be mounted on two guide rails that are transverse to each other. This allows movement around corners. In the case of a folding sliding door, the folding sliding door can always be outside the space between the two guide rails when a corresponding movement is carried out. In general, the freedom of movement of the furniture component can be increased by using two guide rails.

[0021] Use the second guide rail to move the furniture component in a direction transverse to the first guide rail, thereby increasing the lateral load on the first guide rail. As a result, it is more important to unload the support rollers in the end position in order to prevent the support rollers from being crushed.

[0022] It can be arranged as follows: the at least one supporting device has at least one rolling body, preferably wherein: the at least one rolling body is rotatably mounted about a third rotation axis, the third rotation axis being oriented parallel to the second rotation axis of the at least one supporting roller, and / or the at least one rolling body is mounted on the at least one moving mechanism via at least one needle bearing, and / or the at least one rolling body is at least partially made of steel.

[0023] The use of rolling bodies as part of the support device can improve the load relief of the support rollers in the end positions of the guide rails. The round shape of the rolling bodies can simplify the coupling in the end positions.

[0024] In order to ensure that the lateral loads are relieved, it has proven to be advantageous that the rolling bearing is rotatably mounted about an axis of rotation parallel to the second axis of rotation. This positioning allows optimal load relief for the support rollers, since the rolling bearing can be oriented parallel to at least one support roller.

[0025] The use of needle roller bearings provides good support for the rolling elements and also enables a space-saving design of the rolling elements.

[0026] In order to protect the rolling elements from wear and / or flattening, steel can be used at least partially for the rolling elements. However, other hard, non-brittle materials are also conceivable. Even with longer load durations, such materials deform only negligibly. This makes such materials very suitable for continuous unloading of the support rollers.

[0027] It can be provided that at least one supporting device has at least one sliding body.

[0028] Slides can also be used to ensure that the support rollers are unloaded in the end positions of the guide rails. Such slides can be used instead of or in addition to the rolling bodies. The slides can serve as guides for the support device during unloading, so that the available room for movement of the guide device in the region of the end positions is continuously limited and the load on the support rollers in this region is gradually reduced until the coupling position is reached.

[0029] It can be provided that in at least one end position of the at least one guide rail, the at least one supporting device can release the at least one supporting roller from the at least one guide rail, thereby preventing the supporting roller from being crushed, since in this end position the supporting roller is no longer subject to lateral loads.

[0030] It can be provided that the at least one guide rail is at least partially made of aluminum and / or that the side surface of the at least one supporting roller is made of plastic and / or that the at least one supporting device has at least one part that can be fixed in position and is made of steel.

[0031] Since aluminum is light and has a relatively high strength and stability, it can be advantageous to manufacture the guide rail at least partially from aluminum. It can be advantageous for the support rollers to have good and low-noise rolling properties if the support rollers are made from plastic. It is also conceivable in this respect that only the outer shell of the support roller is made from plastic. For the support device, it can be advantageous that at least one part of the support device that can be fixed in position is made from steel in order to avoid wear and deformation of the support device. This ensures that the support rollers are evenly unloaded.

[0032] It may be provided that the first part or the second part of the at least one supporting device has a U-shaped profile which can be detachably coupled to the at least one rolling body of the first part of the at least one supporting device.

[0033] By combining a U-shaped profile with rolling elements, the guidance of the furniture component during the unloading process can be optimized. The U-shaped profile serves to engage the rolling elements and thus to start the unloading process in the end area of ​​the guide rail and then unload the supporting rollers in the coupled state. The U-shaped profile enables lateral loads to be unloaded regardless of direction.

[0034] According to a preferred embodiment of the guiding device, it is provided as follows: the at least one supporting device has at least one pin, preferably wherein: the at least one pin is arranged essentially parallel to the longitudinal direction of the at least one guide rail, and / or at least one second pin is provided, wherein the two pins are preferably spaced apart from each other in the transverse direction of the at least one guide rail, and / or the at least one pin has a slope 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 is essentially made of steel, and / or the at least one pin is arranged in an end region of the at least one guide rail.

[0035] The furniture according to the invention comprises at least one furniture component, in particular a sliding door or a folding sliding door, a furniture body and at least one guide device according to the invention, preferably the furniture has at least one interior space, the at least one interior space can be at least partially covered by the at least one furniture component, kitchen furniture and / or kitchen utensils can be arranged in the at least one interior space, and / or the furniture has at least one empty chamber extending in the depth direction of the furniture, the at least one empty chamber is used to at least partially accommodate the at least one furniture component.

[0036] This arrangement allows the interior of the furniture to be used without restriction. By partially storing the furniture parts in the empty space, the impression is created that the interior of the furniture is part of the room. This impression is reinforced by the fact that no additional guides are required in the bottom area of ​​the furniture parts. If the interior is no longer required, the furniture can be closed and the interior is visually separated from the rest of the room.

[0037] The method according to the invention for guiding at least one furniture component, in particular a sliding door or folding sliding door, relative to a furniture carcass by means of at least one guide device according to the invention comprises the following steps:

[0038] - the weight of the at least one furniture component is supported by the at least one load-bearing roller of the at least one moving mechanism,

[0039] - the furniture component is guided laterally by the at least one supporting roller when the furniture component moves along the at least one guide rail, and

[0040] - By means of the at least one supporting device, the lateral force acting laterally on the at least one supporting roller is unloaded at at least one end position of the at least one guide rail, i.e. the lateral force acting substantially parallel to the first rotation axis of the at least one supporting roller.

[0041] It can be provided that in at least one end position of the at least one guide rail, the at least one supporting device releases the at least one supporting roller from contact with the at least one guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] Figure 1a The figure shows a perspective view of a piece of furniture 20 having a furniture body 21 and a plate-shaped furniture part 2 which can be moved relative to the furniture body 21 and can also be regarded as a folding sliding door. The furniture part 2 consists of individual plate-shaped parts which are connected to each other via hinge fittings 28 (not shown in this figure).

[0059] The furniture parts 2 are mounted on the transverse rails 25 so as to be movable between a first position in which the furniture parts 2 are oriented substantially coplanarly with one another and a second position in which the furniture parts 2 are oriented substantially parallel to one another by means of a guide system 24. Here, the furniture parts 2 can be pushed in a parallel position in a first movement direction M1 into the lateral cavity 23 serving as a receiving chamber.

[0060] The operation is described below with reference to the furniture part 2, wherein the embodiments apply analogously to the second furniture part 2. The guide system 24 comprises a transverse rail 25 with a longitudinal direction L, wherein a guide slide 26 connectable to the furniture part 2 is mounted displaceably along the transverse rail 24.

[0061] exist Figure 1b In the figure, one of the two foldable furniture parts 2 has been moved from a coplanar position to an angled position. The hinge fittings 28 that connect the two furniture parts 2 to each other can now also be seen.

[0062] The furniture component 2 is rotatably mounted on the carrier 11 via two or more hinges 27. Here, the carrier 11 is mounted on at least one guide rail 3 (not shown in this figure) and can be pushed into the hollow space 23 in the depth direction of the furniture body 21. Here, the carrier 11 is formed so that in this position, the carrier 11 is connected to the transverse rail 25 in the longitudinal direction L, and the guide slider 26 can be transferred between the transverse rail 25 and the carrier 11. The guide slider 26 can therefore be pushed onto the carrier 11 in this position.

[0063] The carrier 11 is formed as an elongated column, the length of which corresponds to at least half the height of the furniture component 2 .

[0064] Figure 2a The illustrated furniture 20 is in which the two furniture parts 2 are in a parallel position to each other. The guide slide 26 has been transferred to the carrier 11. The carrier 11 is unlocked by pushing the guide slide 26 and in this state the carrier 11 can be moved along the guide rail 3 (not shown here, see Figure 3 ) is pushed into the cavity 23 in the depth direction of the furniture body 21.

[0065] Figure 2b The furniture 20 is shown in which the furniture component 2 is in a fully pushed-in state. That is, the furniture component 2 is mounted so that it can be pushed inwardly by the guide system 24. Figure 1a The first coplanar position and according to Figure 2b The second parallel position of the furniture part 2 starts to move, in which the furniture part 2 has been pushed into the hollow chamber 23. Here, the hollow chamber 23 is formed by the side wall 14 of the furniture body 21 and the outer wall 17 of the furniture 20 arranged parallel to the side wall 14.

[0066] In this way, an interior space 22 of a piece of furniture 20 , such as a kitchen or a work surface, can be completely covered so that this interior space 22 can be separated from the rest of the living room.

[0067] Figure 3The piece of furniture 20 is shown with the outer wall 17 hidden to illustrate the arrangement of the guide rail 3 in the hollow space 23. At least one guide rail 3 for guiding the carrier 11 and thus the furniture part 2 is mounted on the side wall 14 of the furniture carcass 21.

[0068] In this figure, two guide rails 3 can be seen, which ensure better guidance of the carrier 11. Here, the guide rails 3 are arranged transversely, preferably at right angles, to the transverse rail 25. Other components of the guide device 1 are not visible in this figure and will be described in detail in the following figures.

[0069] Although the guide slide 26 supports part of the weight of the furniture part 2, the carrier 11 and thus the guide device 1 are subject to strong and continuous lateral loads due to the lateral deflection of the furniture part 2 in the closed state. In order to prevent the support rollers 6 from being crushed at least in the closed position, the support device 7 according to the invention can be used.

[0070] Figure 4a The guide device 1 is shown with the carrier 11 in the uncoupled state. Additional illustrations of the furniture component 2 and the furniture carcass 21 have been omitted to provide a better overview. On the right, the guide device 1 and the carrier 11 are shown in their entirety to make it clear which perspective view shows which part. In the detailed view, the guide device 1 can be seen in the uncoupled state.

[0071] The support roller 5 is movably arranged in the guide rail 3. The support roller 6 is covered in this figure, but is located between the support roller 5 and the rolling body 12. The support roller 5 is connected to the carrier 11 here.

[0072] The first part 8 of the supporting device 7 is formed as a rolling body 12 in this embodiment, which is connected to the moving mechanism 4 in a kinematically coupled manner. In this embodiment, at least one rolling body 12 and the supporting roller 6 hidden in this figure are fixed on the same slide 18. The slide 18 is connected to the carrier 11, whereby the carrier 11 connects the supporting roller 6 and the carrier roller 5 to each other and thus simultaneously acts as a moving mechanism 4 together with both rollers.

[0073] Figure 4b Icons in different perspectives Figure 4a Embodiment. The carrying roller 5 is movably mounted on a support 15 in the guide rail 3. The support 15 is used to reduce the wear of the carrying roller 5, preferably to prevent the wear of the carrying roller 5. In addition, the support 15 can be used to reduce the noise. The support roller 6 hidden in this figure is located below the carrying roller 5, and the support roller 6 is connected to the carrier 11 via a slider 18. At least one rolling body 12 is also connected to the slider 18.

[0074] In this embodiment, the part 9 of the support device 7 that can be arranged in a fixed position is formed as a U-shaped profile, in which the at least one rolling body 12 can engage. The slope 10 in the region of the U-shaped profile towards the rolling body 12 can help guide the at least one rolling body 12 during the unloading process and ensure a smooth transition between the uncoupled state and the coupled state.

[0075] Figure 5a From Figure 4a The same perspective diagram guides the device 1. For a better overview, the carrier 11, which is also the moving mechanism 4, is omitted in this figure. The support rollers 5 are arranged to be movable in the guide rails 3. The first part 8 of the support device 7, which is kinematically coupled to the moving mechanism 4, comprises two rolling bodies 12 arranged on a slide 18. Similar to the two rolling bodies 12, two support rollers 6 are arranged on the upper side of the slide 18 (hidden in this figure and only the protruding part is visible).

[0076] The dual design of the support rollers 6 and the rolling bodies 12 is used to provide a stable guide for the not shown moving mechanism 4. This prevents the guide device 1 from getting stuck or wedging due to lateral loads and / or loads acting parallel to the direction of travel.

[0077] The second part of the support device 7, which can be arranged in a fixed position, is formed in such a way that both rolling bodies 12 can be accommodated in the U-shaped profile. As a result, even in the unloaded position, a tilting of the carrier 11 (not shown) and an additional loading of the support rollers 6 (not visible or only the protruding part is visible) can be prevented.

[0078] Figure 5b Shown in side view Figure 5a The side view corresponds to the front view of the piece of furniture 20 in the assembled position. The carrying roller 5 mounted about the first rotation axis D1 is movably mounted on the support 15 in the guide rail 3. The supporting roller 6 is rotatably mounted about the second rotation axis D2 oriented transversely to the first rotation axis D1. The rolling body 12 is mounted on the same slide 18 as the supporting roller 6.

[0079] With this arrangement, the movement of the rolling body 12 is coupled to the movement mechanism 4 (not shown) via the slider 18. The carrying roller 5 and the supporting roller 6 can be connected to the carrier 11 (not shown), which can also realize the function of the movement mechanism 4 in this embodiment.

[0080] The part 9 of the support device 7 that can be arranged in a fixed position is formed as a U-shaped profile, which has ramps 10 on both sides in the longitudinal direction of the guide rail 3. These ramps 10 can help to accommodate the rolling bodies 12 in the U-shaped profile and thus ensure a smooth transition from the uncoupled position to the coupled position.

[0081] Figure 6a The guide device 1 is shown with the carrier 11 in a coupled state. The arrangement is shown in full on the right so that the detailed illustration can be better associated.

[0082] In the coupled state, the U-shaped profile of the fixedly arranged part 9 of the support device 7 has accommodated the rolling bodies 12 of the part 8 of the support device 7 that is movably coupled to the moving mechanism 4 and thereby relieves the support rollers 6 (not visible or hidden in this figure).

[0083] The supporting rollers 6 and the rolling bodies 12 are arranged on the same slide 18, which in turn is connected to the carrier 11. Since the supporting rollers 5 are also connected to the carrier 11, the carrier 11 is part of the moving mechanism 4 in this embodiment.

[0084] Figure 6b The guide device 1 with the carrier 11 is shown in a side view in a coupled position, which corresponds to a front view of the piece of furniture 20 in the assembled position. Figure 5b In comparison, Figure 6b The coupled state of the support device 7 is shown, but no difference can be seen in this viewing angle.

[0085] In the guide rail 3, a support roller 5 is movably mounted on a support 15. The support roller 5 is connected to a carrier 11 on which the furniture part 2 is rotatably mounted. The support roller 6 and the rolling body 12 are arranged on the same slide 18, which is also connected to the carrier 11.

[0086] Figure 7 The second embodiment of the support device 7 according to the invention is shown 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 kinematically coupled to the movement mechanism 4, is arranged on the carrier 11. The part 9 of the support device 7 arranged in a fixed position is arranged on the guide rail 3.

[0087] However, in this figure, the moving mechanism 4 or at least one of the supporting rollers 6 and the carrying rollers 4 is covered by the carrier 11. Figure 1a , 1b , 2a and 2b, an attachment with a receptacle may be provided on the first part 8 of the support device 7 for receiving the guide slide 26 of the transverse rail 25. In order to ensure the transfer from the transverse rail 25 to this attachment, a recess is provided on the side wall 14.

[0088] Figure 8 Exploded view Figure 7The guiding device 1 is composed of a guide rail 3 and a carrier 11. The carrier 11 has a moving mechanism 4 arranged on the carrier 11. The moving mechanism 4 includes at least one carrying roller 5 and at least one supporting roller 6. Only one supporting roller 6 is shown in this figure. The second supporting roller 6 and the carrying roller 5 are covered by the carrier 11.

[0089] The supporting device 7 is composed of two parts, wherein a first part 8 of the supporting device 7 is arranged to be movably coupled to the moving mechanism 4, and a second part 9 of the supporting device 7 is arranged to be fixed in position.

[0090] The first part 8 of the support device 7, which can be coupled to the movement mechanism 4, has a sliding body 13, which serves as a guide during the introduction process and / or during the unloading 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 can be connected to the guide rail 3 by means of screws 16. In this figure, the corresponding counter-piece with a thread for receiving the screw 16 is covered by the second part 9 of the support device 7.

[0091] Fig. 9 Graphics Figure 7 The embodiment of the present invention is in a horizontal cross section when the coupling state is disconnected. Two support rollers 6 are movably arranged in the guide rail 3. The two support rollers 6 are connected to the carrying roller 5 covered by the moving mechanism 4 through the moving mechanism 4.

[0092] The first ramp 10, seen from the illustrated end of the guide rail 3, of the first part 8 of the support device 7, which is arranged to be kinematically coupled to the moving mechanism 4, serves to guide the kinematically 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 support device 7 into the correct final position, thereby ensuring permanent unloading of the support rollers 6 in the final position.

[0093] Fig.10 The diagram shows the coupling state with Fig. 9 Same horizontal section. The first part 8 of the support device 7 , which is kinematically coupled to the displacement mechanism 4 , is in the end position and here adjoins flush with the second part 9 of the support device 7 , which can be arranged in a fixed position.
