The invention concerns an arrangement for guiding at least one moveable furniture part, in particular at least one furniture door or at least one drawer, relative to a stationary furniture part. The arrangement includes at least one guide rail to be mounted in particular to the stationary furniture part, and at least one guide device which can be coupled to the at least one moveable furniture part and which has at least one preferably substantially cylindrical load-transmitting rolling body. The at least one guide rail has at least one track on which the at least one load-transmitting rolling body is moveably mounted, the at least one track has at least one parking position for the at least one load-transmitting rolling body and the at least one parking position corresponds to an end position of the at least one moveable furniture part relative to the stationary furniture part. The invention further concerns an article of furniture comprising at least one moveable furniture part, in particular at least one furniture door or a drawer, a stationary furniture part and at least one such arrangement for guiding the at least one moveable furniture part relative to the stationary furniture part.
To overcome that problem, there are approaches which involve providing the rolling body 106 with a plastic sheath to avoid flattening of the rolling body 106. It is found, however, that the described problem is not overcome thereby but only delayed as the plastic sheath splits sooner or later.
The object of the present invention is to provide an arrangement which is improved over the state of the art for guiding at least one moveable furniture part relative to a stationary furniture part, in which the described disadvantage is avoided, and an article of furniture having such an improved arrangement.
With the arrangement according to the invention, the at least one load-transmitting rolling body and the at least one track have such a configuration at least in the region of the at least one parking position that the at least one track is deformable in that region, forming a depression, and the at least one load-transmitting rolling body is substantially stable in shape.
Therefore the attempt is not made, as in the state of the art, to prevent flattening of the rolling body. Rather, flattening in the region of the parking position is intentionally accepted, although not on the rolling body but on the at least one track. Therefore a depression can be formed in the at least one track in the region of the at least one parking position. That however does not lead to troublesome generation of noise as the depression is arranged in an end position of the at least one moveable furniture part. The at least one load-transmitting rolling body is therefore only moved into and out of the depression, but generally does not have to pass the depression. An exception is represented by a configuration in which the at least one guide device includes more than one load-transmitting rolling body. In that case a plurality of depressions can be formed in the track in the region of the parking position. In the case of a movement of the moveable furniture part out of the end position that can then result in it travelling over depressions, but only in the region of the parking position and not over the entire range of movement along the track, as in the state of the art.
In a preferred embodiment of the invention, the at least one load-transmitting rolling body has a greater hardness in comparison with the at least one track at least in the region of the at least one parking position. That can ensure that the at least one track is deformable in that region to form a depression and the at least one load-transmitting rolling body is substantially stable in shape.
For reasons of stability, advantageously the at least one guide rail has a support structure, preferably of steel, and at least one contact portion, preferably of plastic, particularly preferably of polyoxymethylene, for providing at least a part of the at least one track.
In that connection, it is appropriate for the at least one contact portion to be replaceable and/or to be of a thickness of 1 to 8 mm, preferably 3 mm.
In advantageous embodiments, there can be at least one securing element with which the at least one contact portion can be fixed to the at least one guide rail. Preferably, the at least one securing element is substantially U-shaped and/or has at least one spring element and/or at least one friction element for increasing the friction at a contact contour, in particular in the form of a groove, of the at least one guide rail, and/or the at least one securing element has at least one actuating element by way of which the at least one securing element and the at least one contact portion connected thereto are moveable, and/or there is provided at least one latching device, by way of which the at least one securing element can be releasably fixed to the at least one contact portion, wherein the at least one latching device has at least one latching recess and at least one latching projection.
Contact portions on guide rails for guiding, for example, hanging doors are already known. However, they serve for noise damping purposes or to minimize the wear of the guide rails. Such contact portions are to be distinguished from the contact portions which are used according to the invention and which are used in combination with especially designed rolling bodies and which, in particular, allow the formation of an even long-lasting depression in the region of the parking position of the at least one track.
Therefore, the at least one track is substantially irreversibly deformable, to form the depression, at the at least one parking position of the at least one load-transmitting rolling body.
The at least one load-transmitting rolling body, with the application of a force, is moveable out of the depression formed in the region of the at least one parking position in the at least one track. That, however, does not necessarily have to be perceived as a disadvantage by a user. On the contrary, the fact that the user feels when the at least one rolling body moves into or out of the depression can even be perceived as a positive as in that way the user registers that he has reached an end position, associated with at least one parking position, of the moveable furniture part in relation to the stationary furniture part.
Preferably, the at least one load-transmitting rolling body is formed at least region-wise and preferably completely from steel.
In addition, the at least one track has at least two different material portions, wherein a first material portion is arranged in the region of the at least one parking position and a second material portion is arranged in a dynamic region adjoining the region of the at least one parking position. In that way, the running properties of the moveable furniture part can be coordinated in a specifically targeted fashion.
Alternatively or in addition, the at least one track has at least region-wise a concave configuration in cross-section and/or the at least one load-transmitting rolling body has a peripheral surface which is at least region-wise of a convex configuration in cross-section. Such a configuration has the advantage that at the same time it provides support in the lateral direction.
It has proven desirable if the arrangement includes at least one carrier on which the at least one moveable furniture part can be preferably pivotably mounted and which can be coupled to the at least one guide device, and/or the arrangement has at least one transverse rail which is or can be arranged transversely to the at least one guide rail and at least one carriage which can be coupled to the at least one moveable furniture part and which can be mounted displaceably on the at least one transverse rail.
As stated in the opening part of this specification, protection is also claimed for an article of furniture comprising at least one moveable furniture part, in particular at least one furniture door or a drawer, a stationary furniture part and at least one arrangement according to the invention for guiding the at least one moveable furniture part relative to the stationary furniture part.
According to a preferred embodiment, the at least one moveable furniture part is in the form of a furniture door, in particular a folding-sliding door, and the article of furniture has at least one internal space and at least one side compartment in particular having a shaft shape. The at least one arrangement is designed and is so arranged on the article of furniture to guide the at least one furniture door relative to the stationary furniture part between a closed position outwardly covering the at least one internal space and an open position being at least region-wise sunk in the at least one side compartment and in which the at least one internal space is freely accessible to a user.
In that connection, it has proven to be advantageous if the arrangement for guiding the at least one furniture door extends at least portion-wise in a depth direction of the at least one side compartment and the at least one parking position of the at least one load-transmitting rolling body corresponds to an end position of the at least one furniture door of being substantially completely arranged in the at least one side compartment. Preferably, the at least one track has a further parking position for the at least one load-transmitting rolling body which corresponds to a position of the at least one furniture door in which the at least one furniture door is arranged substantially parallel to and substantially completely outside the at least one side compartment of the stationary furniture part.
And finally, it has been found advantageous if the stationary furniture part has at least one side surface which at least region-wise delimits the at least one side compartment and at which the at least one guide rail of the arrangement for guiding the at least one furniture door is at least portion-wise arranged.
Further details and advantages of the invention will be described more fully hereinafter in the specific description with reference to the drawings in which:
In the specifically illustrated case the guide device 5 includes two load-transmitting rolling bodies 6. In addition there is provided a guide roller 32 for lateral guidance.
The load-transmitting rolling bodies 6 have a greater hardness in comparison with the track 7, at least in the region of the at least one parking position 8, 9. Conversely, that means that the track 7 is softer at least in the region of the at least one parking position 8, 9, than the load-transmitting rolling bodies 6.
The hardness of the load-transmitting rolling bodies 6 and the track 7 can be influenced by various factors. They include the choice of the materials used and the shape.
In the illustrated embodiment the guide rail 4 has a support structure 11 of steel and a contact portion 12 of plastic, preferably polyoxymethylene, for forming the track 7.
The contact portion 12 is replaceable and has a thickness 13 of 1 mm to 8 mm, preferably 3 mm (see also
The load-transmitting rolling bodies 6 are formed from steel.
The guide rail 4 has two vertical legs 30 and 31, wherein the vertical legs 30 and 31 jointly with the support structure 11 define a groove for receiving the contact portion 12. At the same time, the guide roller 32 also bears against the vertical leg 31.
The load-transmitting rolling bodies 6 are mounted rotatably about an axis of rotation 33 which in the position of use is oriented substantially horizontally.
In the illustrated case, the arrangement 1 includes a carrier 17 to which the at least one moveable furniture part can be preferably pivotably mounted and which is coupled to the guide device 5.
In both cases the track 7 has two respective mutually spaced parking positions 8 and 9 which respectively correspond to an end position of the moveable furniture part relative to the stationary furniture part and between which the load-transmitting rolling body 6 is moveably mounted, wherein the rolling body 6 performs a rotation about its axis of rotation 33 in a movement along the track 7.
The drawing diagrammatically shows that the load-transmitting rolling body 6 and the track 7, at least in the region of the parking positions 8, 9, have a configuration such that the track 7 is deformable in those regions by the rolling bodies 6 to form a depression 10, and the load-transmitting rolling body 6 is substantially stable in shape. In comparison with the state of the art shown in
That can involve substantially irreversible deformation of the track 7.
The load-transmitting rolling body 6 is moveable with the application of a force out of the depressions 10 formed in the track 7 in the region of the parking positions 8, 9.
In the embodiment shown in
In the preferred embodiment shown in
The article of furniture 20 has an internal space 21 and two side compartments 22 in the form of shafts. The arrangement 1 is designed and arranged on the article of furniture 20 so as to guide the furniture doors 2 relative to the stationary furniture part 3 between a closed position outwardly covering the internal space 21 (see
The end positions of the moveable furniture doors 2 corresponding to the two parking positions 8 and 9 in
Instead of two furniture doors 2 it is also possible to provide only one or more than two furniture doors 2. In addition, the furniture doors 2 may comprise only one door leaf and not, as in the illustrated case, two door leaves which are hingedly connected together by way of door hinges 26.
The arrangement 1 for guiding the furniture doors 2 respectively extends portion-wise in a depth direction 23 of the two side compartments 22.
In specific terms, the stationary furniture part 3 can have a plurality of side surfaces 24 which region-wise delimit the side compartments 22. At least one respective guide rail 4 of the arrangement 1 for guiding the furniture doors 2 is at least portion-wise arranged on a respective one of the side surfaces 24.
Besides the guide rails 4, the arrangement 1 includes a transverse rail 18 arranged substantially perpendicularly to the guide rails 4 and for each furniture door 2, a respective carriage 19 which is coupled to the furniture door 2 and which can be displaceably mounted on the guide rail 18. The carriages 19 can be entrained by the carrier 17 in a movement between the end positions shown in
Each of the furniture doors 2 is also hingedly connected to a carrier 17 by way of carrier hinges 29.
The article of furniture 20 can also have still further furniture parts like for example a cupboard 25.
Preferably, kitchen furniture 27 like for example bottom cabinets with drawers and/or top cabinets are preferably arranged in the internal space 21 of the stationary furniture part 3, as in the illustrated case. The moveable furniture parts 2 therefore serve to cover a kitchen formed therefrom when not in use.
The securing element 36 can be of a substantially U-shaped configuration as in the illustrated case.
Furthermore, the arrangement can have a spring element 38. In the illustrated case, there are two spring elements 38 which are oriented substantially parallel to each other and form the two vertical legs of the U-shape.
The securing element 36 can have at least one friction element 41 for increasing the friction against a contact contour of the guide rail 4, in particular in the form of a groove 37. In this case, it is appropriate for a plurality of friction elements 41 to be provided, which for example have a triangular cross-section and which are arranged at an outward side of the spring elements 38.
It is desirable if the securing element 36 as in the illustrated case has an actuating element 42, by way of which the securing element 36 and the contact portion 12 connected thereto are moveable. The actuating element 42 can, for example, form the base of the U-shape, and in the installed state can project at the end out of the guide rail 4. The contact portion 12 can be particularly easily replaced in that way.
And finally it is desirable to provide at least one latching device, by way of which the securing element 36 can be releasably fixed to the contact portion 12. the at least one latching device has at least one latching recess 39 and at least one latching projection 40. In the specifically illustrated case, a respective latching projection 40 is arranged at a free end of the spring elements 38 and can latchingly engage into a corresponding latching recess 39 on the contact portion 12.
