Description

Guiding system for a door leaf

Technical Field

The invention relates to a guide system for guiding at least one movably mounted door leaf relative to a side wall of a furniture carcass, comprising:

a carrier which, in the installed state, is mounted so as to be movable in the depth direction of the side wall relative to the furniture carcass,

at least one hinge for movably supporting the at least one door leaf relative to the furniture carcass, wherein the hinge has a first fitting for fastening to the carrier and a second fitting for fastening to the at least one door leaf, wherein the first fitting and the second fitting are pivotably connected to one another, the first fitting and the second fitting being movable relative to one another between a first position in which the at least one door leaf is arranged substantially parallel to the side walls in the mounted state and is movable together with the carrier in the depth direction of the furniture carcass.

The invention further relates to an assembly having at least one door leaf and having a guide system of the type to be described. The invention also relates to a piece of furniture having an assembly of this type or having such a guide system.

Background

CH 693070 a5 shows a cabinet with two door leaves connected to one another in an articulated manner, which are mounted so as to be movable from a first position (in which the door leaves are oriented coplanar with one another) and a second position (in which the door leaves assume a parallel position with respect to one another). Starting from the second position, the door leaves oriented parallel to one another can be pushed into the lateral opening of the cabinet by means of a scissors mechanism. In the first position, in which the door leaves are oriented coplanar with one another, an unsightly shoulder is formed between the outer edge of each door leaf and the end face of the cabinet, which facilitates the entry of dirt into the interior of the cabinet and prevents the cabinet from being cleaned. Furthermore, in order to maintain a uniform overall visual impression, the door leaf and the cabinet should be made of the same material, which increases the manufacturing costs. In addition, in the first position, the hinge for pivotably supporting the door leaf is visible from the outside, wherein there is also the risk that the hinge may be damaged by objects entering the gap formed between the door leaf and the end side of the cabinet.

A guide system for guiding a door leaf is known from WO 2016/081963 a1, wherein the door leaf can be ejected by an ejection device from a folded position (in which the door leaf is accommodated in a laterally arranged cabinet compartment of a furniture carcass) into an open position.

A detachable furniture piece with built-in oven not conforming to this type is disclosed in DE 2401053A 1

A form of construction wherein the cover door covers the front end faces of the opposed side walls in the closed position and is pivotable in the open position up to the front of a recess provided between the oven and the side walls of the demountable furniture.

Disclosure of Invention

The object of the invention is therefore to provide a guidance system of the type mentioned at the outset, while avoiding the disadvantages mentioned above.

According to the invention, this is achieved by a guide system for guiding at least one movably mounted door leaf relative to a side wall of a furniture carcass.

Namely: according to the invention, the first fitting and the second fitting can be moved relative to each other into at least one second position, in which the at least one door leaf at least partially covers an end face of the side wall in the installed state.

The proposed guide device enables the at least one door leaf to cover the end faces of the side walls at least partially or substantially completely in the hinged state, so that a flat surface is formed overall in the front view of the piece of furniture — no steps or gaps are formed. In other words, only a flat surface of the at least one door leaf can be seen in the front view of the piece of furniture, wherein in the second position of the fitting the furniture body is covered by the at least one door leaf.

The hinge can have at least four hinge axes, by means of which the first fitting and the second fitting are pivotably connected to one another. Provision is preferably made for the hinge to have exactly four hinge axes, as a result of which the manufacture of the hinge is particularly simple.

The first fitting part and the second fitting part can be pivotably connected to one another via a first lever and via at least one second lever, it being preferably provided that the first lever and the second lever have different lengths. It can also be provided that the hinge has a guide, by means of which at least one of the levers is mounted so as to be movable relative to one of the fittings when the fittings are moved relative to one another.

Detailed Description

Fig. 1a shows one possible use of a guide system 2 for guiding at least one door leaf 3b, which in the installed position is connected in an articulated manner to a further door leaf 3a via a vertically extending axis 5 a. Alternatively, only one single door leaf 3b or

additional door leaves

4a, 4b can also be provided, which are likewise pivotably connected to one another via a vertically extending axis 5 b. The

door leaves

3a, 3b and 4a, 4b are mounted so as to be movable by the guide system 2 relative to a furniture carcass 36 of the piece of furniture 37, which carcass is fixed during operation. The guide system 2 can be used, for example, as a space divider system, so that in a living space, for example, a furniture carcass 6 (in the form of a kitchen area, office area, storage room, rack, etc.) shown in fig. 1a can be passed through the

furniture parts

3a, 3 b; 4a, 4b are completely covered and can thus be visually isolated from the rest of the living space. However, the guiding system 2 can also be used in a cabinet system, for example a mobile cabinet. The operating principle is explained below with reference to the

door leaves

3a and 3b, wherein the same embodiment applies for the

door leaves

4a, 4 b.

The

door leaves

3a, 3b are movably supported by the guide system 2 between a first position (fig. 1a) in which the

door leaves

3a, 3b are oriented substantially parallel to each other, and a second position (in which the

door leaves

3a, 3b are oriented substantially coplanar with each other). In the first position, a person can freely access the furniture carcass 6, wherein the two

door leaves

3a, 3b can be accommodated in the push-in shaft 7a laterally of the side wall 8a in a space-saving manner. The push-in shaft 7a is formed by a cavity arranged between the

side walls

8a, 71, into which the

door leaves

3a, 3b can be completely inserted. The other two

door leaves

4a, 4b can be accommodated in a further lateral push-in shaft 7b in a parallel position to each other.

The guiding system 2 comprises a first guide rail 9 having a longitudinal direction (L) for movably guiding the

door leaves

3a, 3 b. The first guide rail 9 can be fastened, for example, to a space covering, a space wall or to a fixed furniture carcass 36. Furthermore, the guide system 2 comprises at least one second guide rail 13a (fig. 3a) which, in the installed state, extends transversely to the longitudinal direction (L) of the first guide rail 9 and by means of which the

door leaves

3a, 3b can be moved in the depth direction (Z) or in the direction opposite thereto. Furthermore, a guide device 10 is provided which can be connected to the first door leaf 3a and can be moved relative to the first and

second guide rails

9 and 13 a. The other two

door leaves

4a, 4b are movably mounted via a separate guide 10 a. Starting from the position shown in fig. 1a, in which the door leaves 3a, 3b assume a mutually parallel position and are accommodated in the lateral push-in shaft 7a, the

furniture parts

3a, 3b can be moved into an overpressure position as a result of the application of mechanical forces in the depth direction (Z), as a result of which the first drive 12 (not visible here) can be triggered. After the triggering of the first drive 12 is completed, the door leaves 3a, 3b can be moved by the first drive 12 into the position shown in fig. 1b, in which the door leaves 3a, 3b are outside the push-in shaft 7a and furthermore occupy a position substantially parallel to one another. Starting from the position shown in fig. 1b, the two

door leaves

3a, 3b can be moved, if necessary, by means of an opening device from the parallel position into a position in which they are open to each other, so that the door leaves 3a, 3b assume an angular position relative to each other. A further drive 53 (fig. 13c) can optionally be provided, so that the door leaves 3a, 3b can be moved into a position coplanar with one another (fig. 2 b).

Fig. 2a shows the movement of the door leaves 3a, 3b relative to one another after fig. 1b, the other two

door leaves

4a, 4b having been moved into a position in which the door leaves 4a, 4b are aligned coplanar with one another and cover the furniture carcass 6. The guide means 10 has at least one hinge 41 for fixing the first door leaf 3 a. The guide system 2 comprises a carrier 11 which is mounted movably transversely to the longitudinal direction (L) of the first guide rail 9 and which is connected to at least one further joint 18 for fastening the second door leaf 3 b. In the illustrated embodiment, the carrier 11 is connected to a vertically extending column 14, which together with the carrier 11 is mounted so as to be movable in a depth direction (Z) extending transversely to the longitudinal direction (L) of the first guide rail 9. Here, two or more hinges 18 can also be provided on the vertical column 14 for movably supporting the second door leaf 3b, said hinges being spaced apart from one another in the height direction of the column 14. The guide device 10 connected to the first door leaf 3a can be transported to and fro in an intersection area 45 between the first and

second guide rails

9, 13a, viewed in plan view on the first and

second guide rails

9, 13a in the installed position. The drive 53 (fig. 13c) can move the guide device 10 out of the first guide rail 9 into a position in which the joint 41 and the joint 18 of the guide device 10 are oriented toward one another in such a way that the door leaves 3a, 3b connected to the

joints

41, 18 are oriented substantially coplanar with one another in the installed state, as shown in fig. 2 b.

Fig. 3a shows a piece of furniture 37 in a perspective view, wherein the first guide 9 and the second guide 13a for guiding the door leaves 3a, 3b are visible. In the exemplary embodiment shown, two

second guide rails

13a, 13b are provided, which are spaced apart from one another in the height direction. The carrier 11 is movable-together with the column 14 connected thereto-in the depth direction (Z) and in a direction opposite to the depth direction (Z). The first guide rail 9 and the second guide rail 13a can be designed as separate components, which can be located either at the same height position or at different height positions in the installed state. Alternatively, it is possible for the first guide rail 9 and the second guide rail 13a to be formed in one piece and to be connected to one another via curved sections. The intersection region 45 is obtained in plan view by a region in which the

guide rails

9, 13a or imaginary extensions of the

guide rails

9, 13a intersect with each other. The guide system 2 comprises a first drive 12, by means of which the guide device 10 is pulled in from the second guide track 13a at least in sections in the direction of the first guide track 9 and/or from the intersection region 45 along the second guide track 13a at least in sections.

Fig. 3b shows the area enclosed in fig. 3a in an enlarged view. The door leaf 3a is connected to a movably mounted guide 10, by means of which the

door leaf

3a, 3b can be moved along the first and

second guide rail

9, 13 a. A carrier 11 in the form of a movable slide can be seen, which is separate from the first guide rail 9 and which in the transport position is connected to the first guide rail 9 in the longitudinal direction (L) in such a way that the guide 10 connected to the first door leaf 3a can be transported back and forth between the first guide rail 9 and the carrier 11. The guide device 10 can comprise a first pulley 15a having a vertical axis of rotation for absorbing lateral forces and at least one second pulley 15b having a horizontal axis of rotation for absorbing vertical forces, wherein the

pulleys

15a, 15b are movably mounted along a profile section 9a of the first guide rail 9 extending in the longitudinal direction (L). The carrier 11 likewise comprises a profile section 11a with a cross section which corresponds to the shape and size of the profile section 9a in cross section, so that the guide device 10 can be transported back and forth between the first guide rail 9 and the carrier 11. The carrier 11 can have, for example, at least two

guide channels

16a, 16b extending in the longitudinal direction (L) for guiding the

pulleys

15a, 15 b.

In the transport position of the carrier 11 shown, the guide means 10 which can be moved along the first guide rail 9 are still present on the first guide rail 9. In this transport position, the carrier 11 is releasably latched to the first guide rail 9, wherein the latching can be released by moving the guide 10 into the carrier 11 or onto the carrier 11. After the unlocking is completed, the carrier 11 can be moved, together with the guide device 10 and the two

furniture parts

3a, 3b, in a horizontal direction along a depth direction (Z) which extends transversely, preferably perpendicularly, to the longitudinal direction (L) of the first guide rail 9. The carrier 11 is connected to a vertically extending column 14, which can be driven at least in sections by means of a first drive 12 in the depth direction (Z) and/or in a direction extending counter to the depth direction (Z). The column 14 is mounted movably relative to the

second guide rails

13a and 13b, which in the mounted state are spaced apart from the first guide rail 9 in the height direction.

Fig. 4a shows the door leaves 3a and 3b after they have been pivoted relative to one another, starting from fig. 3a, about the vertical axis 5a and now assume a position substantially parallel to one another. Fig. 4b shows the area encircled in fig. 4a in an enlarged view, with the guide device 10 on the carrier 11 in the transport position. In this case, it can be provided that the length of the carrier 11 measured in the longitudinal direction (L) is greater than the width of the guide 10 measured in the longitudinal direction (L). The contour section 9a of the guide rail 9 and the contour section 11a of the carrier 11 are identically configured in cross section at least in sections and are aligned relative to one another in the transport position, so that the

pulleys

15a, 15b of the guide device 10 can be moved back and forth between the first guide rail 9 and the carrier 11 without interfering abutment edges. Starting from the position shown in fig. 4b, the carrier 11 together with the guide 10 (and thus the door leaves 3a, 3b) can be driven at least in sections in the depth direction (Z) by the force of the drive 12.

Fig. 5 shows a detail region of the piece of furniture 37 in a perspective view from above. A carrier 11 can be seen which latches with the first guide rail 9 and which can be unlocked from the first guide rail 9 as a result of the introduction of the guide device 10, so that the carrier 11 can be moved together with the guide device 10 into the push-in shaft 7a formed between the side wall 8a and the side wall 71 after unlocking has been completed. The relative position of the

side walls

8a, 71 to each other can be determined via at least one spacer holder 72. The carrier 11 is connected to a vertically extending column 14, wherein at least one hinge 18 is provided on the carrier 11 and/or on the column 14 for movably supporting the door leaf 3 b. The hinge 18 enables the door leaf 3b to be moved from a second position (in which the door leaf 3b at least partially covers the vertically extending end side 71a of the side wall 71) and a first position (in which the door leaf 3b extends substantially parallel to the side wall 71), such that the door leaf 3b can be moved into the push-in shaft 7 a. Preferably, the door leaf 3b completely covers the end faces 71a of the side walls 71, wherein the outer side 73 of the door leaf 3b, as shown in fig. 5, extends substantially flush with the side faces 71b formed by the side walls 71.

Fig. 6 shows a perspective view of the guide system 2 with the carrier 11, which is mounted so as to be displaceable in the depth direction (Z) of the

side walls

8a, 71 together with the vertically extending column 14 connected thereto. The carrier 11 and the column 14 are movably supported along the second guide rail 13a via at least one support pulley 17b rotatably supported on the column 14. At least one hinge 18 is provided on the carrier 11 and/or on the column 14 for pivotably mounting the door leaf 3b, wherein the hinge 18 has a first fitting 75 for fastening to the column 14 and a second fitting 76 for fastening to the door leaf 3 b. The second fitting 76 has at least one fixing point 77 (e.g. a hole) for mounting the door leaf 3 b. The first fitting 75 and the second fitting 76 are pivotably connected to one another via a first lever 78 and via a second lever 79, wherein the first lever 78 is connected to the second fitting 76 via a joint shaft 80b and the second lever 79 is connected to the second fitting 76 via a joint shaft 80 d.

Fig. 7 shows a top view of a piece of furniture 37, in which a carrier 11 arranged in the lateral push-in shaft 7a and movably supported in the depth direction (Z) is visible together with a hinge 18 connected thereto for pivotably supporting the door leaf 3 b. In the illustrated figures, the door leaf 3b is in a second position in which the door leaf 3b substantially completely covers the vertically extending end side 71a of the side wall 71 and the outer side 73 of the door leaf 3b extends substantially flush with the side 71b formed by the side wall 71. The first fitting 75 is connected to the carrier 11, while the second fitting 76 is fixed to the inner side of the door leaf 3 b. The first fitting 75 and the second fitting 76 are pivotably connected to one another via a first lever 78 and via at least one second lever 79, wherein it is preferably provided that the first lever 78 and the second lever 79 have different lengths. The first lever 78 is connected to the first fitting 75 via a first hinge shaft 80a and to the second fitting 76 via a second hinge shaft 80 b. In contrast, the second lever 79 is connected to the first fitting 75 via a third hinge shaft 80c and to the second fitting 76 via a fourth hinge shaft 80 d. In this case, it can be provided that, in a plan view of the hinge 18, a first straight line between the first hinge axis 80a and the third hinge axis 80c is longer than a second straight line extending between the second hinge axis 80b and the fourth hinge axis 80 d. Further preferred embodiments: the lengths of the straight lines imaginary between all the

hinge shafts

80a, 80b, 80c, 80d are different from each other. The first straight extension 81a and the second straight extension 81b form an acute angle (α), preferably between 10 ° and 30 °, with respect to each other in the illustrated second position of the hinge 18 and in a top view of the hinge 18. In the mounted state, the hinge shaft 80d of the shorter second lever 79 is disposed closer to the outer side surface 73 of the door 3b than the hinge shaft 80b of the longer first lever 78.

Fig. 8a shows a further plan view of the piece of furniture 37, in which the door leaf 3b has been pivoted by the hinge 18 from the position shown in fig. 7 about an imaginary vertically extending axis. Namely: the outer side 73 of the door leaf 3b is already inclined in the first pivot angle region of the door leaf 3b relative to the vertically extending end side 71a of the side wall 71. Fig. 8b shows the position of the door leaf 3b pivoted further with respect to fig. 8 a.

Fig. 9a and 9b each show a further relative position of the door leaf 3 b. Furthermore, fig. 9b shows that the first door leaf 3a, which is moved along the first guide rail 9 by the guide device 10, is gradually moved closer in a direction parallel to the second door leaf 3 b.

Finally, fig. 10a shows a (first) position in which the door leaves 3a, 3b are oriented parallel to one another. It can be seen that the contact surface of the second fitting 76 which is in contact with the inner side of the door leaf 3b is offset in a plan view of the hinge 18 parallel to the inner side of the side wall 71 and at right angles to the longitudinal direction (L) of the first guide rail 9 by a dimension Δ X, wherein this dimension Δ X is greater than the material thickness of the door leaf 3 b. Starting from the position shown in fig. 10a, the two

door leaves

3a, 3b, together with the carrier 11 and the column 14, can be moved in the depth direction (Z) into the lateral push-in shaft 7a (fig. 10 b).

Fig. 11a shows a perspective view of the hinge 18 with a first fitting 75 and a second fitting 76, which are pivotably connected to one another via two

levers

78, 79 and via

hinge shafts

80a, 80b, 80c, 80 d. The second fitting 76 has a base 82 through which hinge

shafts

80b, 80d extend. Fig. 11b shows the hinge 18 in an exploded view. The first lever 78 can have two U-shaped profiles spaced apart from one another in the longitudinal direction of the lever 78, through which the

hinge shafts

80a and 80b extend, respectively. The U-shaped profile of the lever 78 can, as shown, have lever arms of different lengths, through which the

respective pivot axes

80a, 80b extend. And the second lever 79 has a curved shape.

Fig. 12a shows the guide device 10, which is mounted movably on the first guide rail 9, in a perspective view. The guide device 10 can comprise a plurality of

pulleys

15a, 15c, 15d, 15e having vertical and horizontally extending axes of rotation, wherein the

pulleys

15a, 15c, 15d, 15e are movably supported along the contour section 9a of the first guide rail 9. The guide device 10 comprises a retaining arm 40, wherein a fitting 41 to be fixed on the door leaf 3a is pivotably connected to the retaining arm 40 via a pivot axis 44 extending vertically in the installed position. The fitting 41 has a plurality of

fastening points

42a, 42b for fastening to the door leaf 3 a.

Fig. 12b shows the guide device 10 movably mounted on the first guide rail 9 in a transverse sectional view. The first rail 9 has a plurality of cavities 43 in cross section, which are separated from one another by profile webs. The

pulleys

15a, 15c, 15d, 15e are mounted so as to be movable along the first guide rail 9, wherein a fitting 41 to be fixed on the door leaf 3a is pivotably connected to the holding arm 40 via a vertically extending pivot axis 44.

Fig. 13a to 13c show the movement of the door leaves 3a, 3b in successive steps. Fig. 13a corresponds to a position in which the door leaves 3a, 3b are oriented coplanar with one another, wherein the door leaf 3b covers an end side 71a of the side wall 71, which is not shown here. The door leaf 3a is connected to a guide 10 (fig. 13b) which is movable along the first guide rail 9. The carrier 11 latches with the first guide rail 9 in the transport position, wherein an automatic unlocking between the carrier 11 and the first guide rail 9 is brought about by the insertion of the guide device 10 into the carrier 11 (fig. 13 b). After the unlocking of the carrier 11 has been completed, the door leaves 3a, 3b oriented parallel to one another, together with the carrier 11 and the column 14 connected thereto, are pulled in along the second guide rail 13a in the depth direction (Z) (fig. 13 c). The pulling of the door leaves 3a, 3b into the push-in shaft 7a can be effected by means of a catch 20, which is mounted on the mast 14 so as to be pivotable about a rotational axis and can be acted upon by force by means of at least one energy store 21. Supported on the driver 20 is a rotatable pressure roller 22, which can be pressed against a control curve 23 fixed to the side wall 8a by the force of an accumulator 21, so that the door leaves 3a, 3b oriented parallel to one another can be at least partially or completely pulled into the push-in shaft 7a in the depth direction (Z). It is also possible to see a drive 53, by means of which the door leaves 3a, 3b can be driven into a position coplanar with one another counter to the depth direction (Z) after being removed from the push-in shaft 7 a. The drive 53 can have, for example, a spring device and a pressure element which is acted upon by the spring device, wherein the pressure element can be moved along the adjusting contour in the event of a movement of the door leaves 3a, 3 b.
