The invention concerns an arrangement for guiding a sliding door or folding-sliding door on a furniture wall. The invention further concerns an article of furniture comprising such an arrangement and a method of mounting such an arrangement to a furniture wall.
Arrangements as noted above are known, for example, from WO 2018/129568 A1 to the present applicant. In principle, the challenge in regard to guiding a sliding door or folding-sliding door on a furniture wall is that, because of its weight, the sliding door or folding-sliding door tends to tilt, which subsequently leads to jamming of the door between the vertically mutually spaced guides of the guide system and thus makes displacement of the door impossible or at least substantially more difficult.
WO 2018/129568 A1 proposes for resolving that problem that a cable pulling device includes at least two mutually separate pulling cables. A first of those two pulling cables is arranged between the guide body of the first guide system and at least an end of the guide of the first guide system and is arranged in non-connected relationship with respect to the second guide system, and a second of those two pulling cables is arranged between the guide body of the second guide system and at least an end of the guide of the second guide system and is in non-connected relationship with respect to the first guide system. In that case, those two pulling cables are coupled by a synchronization device.
A disadvantage with such a structure according to the state of the art, however, is that the construction of such a cable pulling device is complicated and expensive. Fitment of such a cable pulling device, in particular the synchronization device which is in the form of a synchronization bar, is a difficult procedure by virtue of the necessary manufacturing tolerances. A further disadvantage is that such a cable pulling device and in particular the winding devices on or in the carrier take up a comparatively large amount of structural space.
The object of the present invention is to avoid the described disadvantages in the state of the art and to provide an arrangement, that is improved over the state of the art, for guiding a sliding door or folding-sliding door on a furniture wall, an article of furniture comprising at least one such arrangement and a method of mounting such an arrangement to a furniture wall.
In an arrangement according to the invention for guiding a sliding door or folding-sliding door on a furniture wall it is accordingly provided that the compensation device in addition to the at least one cable pulling device has at least one pivotal lever mechanism. The at least one pivotal lever mechanism includes at least two hingedly interconnected pivotal levers which are pivotable relative to each other upon a movement of the carrier by the two guide systems along the furniture wall.
That provides an arrangement for guiding a sliding door or folding-sliding door with rigidity and stability that is improved over the state of the art. By virtue of the modified cable guidance configuration of a pulling cable of a cable pulling device an arrangement according to the invention also requires less structural space in comparison with an arrangement known from the state of the art. That reduces both the complexity and the space requirement as well as the manufacturing costs of an arrangement according to the invention over arrangements from the state of the art.
In regard to a method of mounting an arrangement according to the invention it is provided that in a first method step the first guide system or the second guide system is fixed to the furniture wall, in a second method step the other guide system is fixed to the furniture wall at a vertical spacing relative to the guide system fixed to the furniture wall in the course of the first method step, in a third method step the carrier is connected in motionally coupled relationship to the two guide bodies of the guide systems, and in a fourth method step at least one of the at least two pivotal levers is connected to one of the two guide systems and/or to the furniture wall.
There is further provided an article of furniture according to the invention comprising at least one furniture wall, at least one sliding door or folding-sliding door and at least one arrangement for guiding the at least one sliding door or folding-sliding door at the at least one furniture wall, preferably wherein the at least one furniture wall at least partially defines a shaft-shaped hollow space in the article of furniture, in which the at least one sliding door or folding-sliding door can be arranged.
The at least one pivotal level mechanism can be pivoted between a parallel position in which the at least two pivotal levers are arranged substantially parallel to each other and at least one spread position in which the at least two pivotal levers include an angle greater than 0° relative to each other, preferably wherein the at least two pivotal levers in the at least one spread position form substantially a Y-shape.
Such a Y-shaped arrangement of the pivotal levers in conjunction with a cable pulling device results in improved rigidity of the arrangement in comparison with arrangements from the state of the art.
In an embodiment of the invention, the at least two pivotal levers in any position are arranged in a common central plane. That promotes easier fitment and reduces the structural space required.
Furthermore, the carrier has at least one guide for displaceably mounting an end of at least one of the at least two pivotal levers, preferably wherein the at least one guide is arranged substantially centrally on the carrier and/or extends substantially over a fifth of the total length of the carrier.
Preferably, the at least one cable pulling device has at least one and preferably precisely one cable which is fixed with an end, preferably with both ends, to the carrier. If only one cable is provided, the structure and assembly of the arrangement is still further simplified.
Also, the at least one cable pulling device can have at least one cable tensioning device with which the tension of a cable of the at least one cable pulling device is adjustable, preferably wherein the at least one cable tensioning device is arranged on the carrier.
Further, the at least one cable pulling device can have at least one deflection device, preferably with a deflection roller, by which a cable of the at least one cable pulling device can be deflected. Preferably, the at least one deflection device is or can be arranged at an end of at least one of the at least two pivotal levers and/or at one of the two guide systems or at the furniture wall.
These measures facilitate fitment of the cable and improve the stability and rigidity of the arrangement.
Particularly preferably, the compensation device in a delivered state of the arrangement is pre-assembled, at least partially, preferably completely, on the carrier. Fitment of the arrangement to a furniture wall is considerably facilitated thereby.
Further, at least one equalization device can elastically displaceably connect one of the at least two pivotal levers to the carrier. Upon adjustment of an inclination of the carrier, the equalization device can compensate for a change, caused by the inclination operation, in the position of the one pivotal lever of the at least two pivotal levers and can thus obviate possible jamming of the pivotal lever mechanism.
Also, the at least one equalization device can include at least one guide element, at least one guide pin, at least one elastic element, preferably a spring, and at least one pivotal lever receiving means. The elastic element however can also be, for example, in any suitable form.
Regarding the method according to the invention, the at least two hingedly interconnected pivotal levers of the at least one pivotal lever mechanism can be transferred between the third and fourth method steps out of a parallel position in which the at least two pivotal levers are arranged substantially parallel to each other into at least one spread position in which the at least two pivotal levers include an angle of greater than 0° relative to each other, preferably wherein at least one cable of the at least one cable pulling device is unwound from a cable supply.
In a further method step, a cable tension of the at least one cable of the at least one cable pulling device can be adjusted.
In addition, in a further method step, a sliding door or folding-sliding door can be mounted to the carrier.
Further details and advantages of the invention will be described more fully hereinafter by means of the specific description with reference to the drawings in which:
Provided laterally of the article of furniture 100 is a hollow space 101 formed from two mutually spaced furniture walls 3. A folding-sliding door 2 can be moved into that hollow space 101 in the state of being folded together. When the folding-sliding door 2 is spread open it conceals the interior of the article of furniture 100.
The folding-sliding door 2 is composed of two door leaves which are folded together in the position shown in
Arranged adjoining the hollow space 101 is a further part of the article of furniture 100, for example a cupboard. When the folding-sliding door 2 is in a spread position and the further part of the article of furniture 100 is closed then the folding-sliding door 2 and the further part of the article of furniture 100 form a continuous front to the article of furniture.
The cable pulling device 16 in this case includes a cable 20, two deflection devices 16b each having a deflection roller 16c, a cable tensioning device 16a and a cable supply 16d (not shown).
The pivotal lever mechanism 17 includes two pivotal levers 17a, 17b, a second pivotal lever 17b being arranged with a first end in the center of the first pivotal lever 17a and with a second end on a carrier 11. The first pivotal lever 17a is connected at a first end to the guide 19 (not visible) of the carrier 11 while the second end in an installed state is connected to a first guide system 6 and/or a furniture wall 3.
A first deflection device 16b is arranged in a region at the lower end of the carrier 11 at the second guide device 6 or the furniture wall 3. The cable 20 extends therefrom to the second deflection device 16b which is arranged in the region of the second end of the first pivotal lever 17a at the second end of the first pivotal lever 17a or at the first guide device 4 or at the furniture wall 3. The cable 20 is arranged at a first end in the region of the first deflection device 16b on the carrier 11 or a second guide body 10. A second end of the cable 20 is fixed in an upper region of the carrier to the carrier 11 or a first guide body 9 and can be tensioned by way of the cable tensioning device 16a.
In a second step 202 a second guide system 6 including a guide 8 and a guide body 10 mounted displaceably on the guide 8 is fixed to the furniture wall 3 spaced at a vertical spacing 5 from the first guide system 4.
Fixing of the guide systems 6, 7 to the furniture wall 3 is preferably effected by screwing but all other suitable methods are also conceivable.
It can be seen that the carrier 11 centrally has a guide 19 for displaceably mounting an end of at least one of the at least two pivotal levers 17a, 17b. The pre-assembled pivotal lever mechanism 17 is arranged within the carrier 11. The cable pulling device 16 is also already pre-assembled to the carrier 11. It is basically however also possible for no parts of the arrangement 1 to be pre-assembled.
In the course of the third method step 203 a first deflection device 16b which includes the cable supply 16d is also mounted to the furniture wall 3 and/or to the second guide system 6.
In a fifth step 205 the cable 20 is tensioned by way of a cable tensioning device 16a (not visible) to ensure the best possible stability and rigidity for the arrangement 1.
A sixth method step 206 is not shown, in the course of which a sliding door or folding-sliding door 2 is mounted to the carrier 11.
When the carrier 11 is in a position at the left, that is to say in a position in which the sliding or folding-sliding door 2 is completely extended from the hollow space 101 then the carrier 11 or the sliding or folding-sliding door 2 is supported primarily by the pivotal lever mechanism 17. In that situation the second pivotal lever 17b is subjected to a tensile loading and the first pivotal lever 17a is subjected to a pressure loading.
When the carrier 11 is in a position in the center (
Depending on the position of the carrier 11 or the sliding or folding-sliding door 2 they are supported more by the pivotal lever mechanism 17 or by the cable pulling device 16.
When the carrier 11 is in a position to the right (
The detail A of
The second pivotal lever 17b is thus arranged on the carrier 11 elastically displaceably by way of the equalization device 21. If the inclination of the carrier 11 is adjusted corresponding to the arrow N (
