The present invention relates to a guidance system for guiding at least one movably mounted door leaf relative to a furniture body, comprising:

• a first guide rail for guiding the at least one door leaf,
• a second guide rail for guiding the at least one door leaf, the second guide rail running transversely relative to the first guide rail in an assembled state,
• a carrier which can be moved at least along the second guide rail and which is connected or connectable to the at least one door leaf via at least three furniture hinges which can be arranged at a distance from one another or which are arranged in the assembled state, the carrier having a longitudinal direction.

The invention further relates to a piece of furniture with a furniture body, at least one door leaf which is movably mounted relative to the furniture body and with a guide system of the type to be described for moving the at least one door leaf relative to the furniture body.

The invention further relates to a method for mounting a door leaf on a support of a guide system of the type to be described.

A guide system for two hingedly connected door leaves, which can be retracted via a support into a side slot of a furniture body, is, for example, in WO 2018/129574 A1 shown.

In the US 2007/159037 A1 a non-generic guide system for moving a door leaf for a media cabinet is shown. In a first position, the door leaf covers the furniture body, so that, for example, a screen arranged in the furniture body is covered. In another position, the door leaf can be pushed into the side of the furniture body, allowing an unobstructed view of the screen. Moving the door leaf along the front edge of the furniture body is not possible due to the lack of a guide rail. In Fig. 5 the US 2007/159037 A1 It can also be seen that two furniture hinges are arranged on two separate brackets for pivoting the door leaf, the brackets being able to be inserted into the interior of the furniture body together with the furniture hinges and the door leaf. The disadvantage of this is that the assembly of the door leaf is somewhat complicated, as the hinge cups of the furniture hinges each have to be sunk precisely into corresponding openings in the door leaf. If the furniture hinges are also provided with an adjustment device, the settings of the furniture hinges must be coordinated with one another, otherwise this would lead to misalignment, tension or jamming of the door leaf.

In the US 2013/0232878 A1 A guide system for a door leaf is shown, which can be retracted into a side slot of a furniture body via a vertical support. To support the door leaf, several hinges are provided, which can be arranged on a common profile rail that is separate from the support. To install the profile rail, it must be pushed onto the carrier in a longitudinal direction. In order for the profile rail to be able to be pushed onto the vertical support directly on site, there must be sufficient space in the height direction. However, such space is not available in most assembly situations.

The object of the present invention is to provide a guidance system of the type mentioned at the beginning while avoiding the disadvantages discussed above.

This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention, it is provided that all furniture hinges, via which the at least one door leaf can be connected to the carrier or is connected in the assembled state, are arranged or can be arranged on a common mounting part that is separate from the carrier, the mounting part being detachable from the carrier via at least one fastening device is connectable and that the assembly part can be releasably connected to the carrier in a direction transverse to the longitudinal direction of the carrier.

Thus, in a first assembly step, the at least one door leaf must be attached to the assembly part via the furniture hinges. In a further assembly step, the assembly part - together with the door leaf attached to it - can be pushed onto the carrier in a direction transverse to the longitudinal direction of the carrier (for example from the front), which results in a comfortable and easy-to-carry assembly of the door wing on the carrier.

According to one exemplary embodiment, it can be provided that the mounting part can be releasably connected to the carrier by pushing it on, pressing it on or hanging it on.

All furniture hinges for fastening the at least one door leaf are arranged or can be arranged on the common mounting part that is separate from the carrier, so that the mounting part with the furniture hinges pre-assembled thereon can be fastened to the carrier as a common structural unit via at least one fastening device. This eliminates the need to mount the furniture hinges individually on the support. A particular advantage of the invention is that a position of the mounting part - together with the furniture hinges arranged thereon - can be adjusted relative to the carrier by at least one adjusting device, so that when the mounting part is adjusted, all furniture hinges provided for fastening the door leaf are synchronous and uniform relative to the carrier are adjustable. By synchronously adjusting the furniture hinges, tension or jamming of the door leaf can be largely eliminated.

The furniture hinges are either already pre-assembled on the common assembly part or can alternatively be detachably attached to the assembly part. For the purpose of releasably fastening the furniture hinges, recesses and/or locking elements can be arranged or formed on the mounting part, through which the furniture hinges can be releasably locked (for example snapped on) to the mounting part.

According to one exemplary embodiment, it can be provided that at least four furniture hinges are arranged or can be arranged on the mounting part. The number of furniture hinges naturally depends on the height and weight of the door leaf. Therefore, more than four furniture hinges can be provided on the assembly part, which in an assembly state are each spaced apart from one another in a longitudinal direction of the assembly part.

The mounting part can, for example, be designed as an elongated rail, it being preferably provided that the rail rests on the carrier substantially over its entire length when connected to the carrier.

The assembly part can be designed either in one piece or in several parts. In the case of a multi-part design of the mounting part, two or more sections can be provided, which are designed to be fastened to one another (for example by a fastening adapter and/or by screws), so that the mounting part as a finished module has at least three furniture hinges for fastening the at least one door leaf.

The at least one fastening device for fastening the mounting part to the carrier can, for example, have at least one projection arranged or formed on the carrier or on the mounting part, the projection engaging in a connected state of the mounting part with the carrier in a recess arranged on the mounting part or on the carrier. The at least one projection can therefore be arranged or formed either on the mounting part or on the carrier, the projection engaging in a corresponding recess in the carrier or the mounting part in a connected state with the carrier. According to one exemplary embodiment, it can be provided that at least two projections are provided, which are spaced apart from one another in a longitudinal direction of the mounting part and/or in a longitudinal direction of the carrier.

According to the invention, at least one adjustment device is provided, by means of which a position of the mounting part relative to the carrier can be adjusted when the mounting part is connected to the carrier. The adjusting device has at least one rotatably mounted adjusting wheel, whereby a rotation of the adjustment wheel allows the position of the mounting part to be adjusted relative to the carrier. The at least one setting wheel can have a tool holder, the setting wheel being rotatable by rotating the tool holder using a tool, for example a screwdriver.

• Verbinden der am Montageteil angeordneten Möbelscharniere mit dem wenigstens einen Türflügel, und
• lösbares Verbinden des Montageteiles mit dem Träger des Führungssystems.

The method according to the invention for mounting at least one door leaf on a support of a guide system of the type in question is characterized by the following steps:

• Providing the assembly part separate from the carrier, on which at least three or more furniture hinges are or will be arranged for the movable mounting of the at least one door leaf,
• Connecting the furniture hinges arranged on the mounting part to the at least one door leaf, and
• detachable connection of the assembly part to the carrier of the guide system.

According to a further method step, it can be provided that in a connected state of the mounting part on the carrier, a position of the mounting part relative to the carrier is adjusted by the at least one adjusting device

Fig. 1a shows a perspective view of a piece of furniture 1 with a furniture body 2 and door leaves 3a, 3b, 4a, 4b that can be moved relative to it. The door leaves 3a, 3b, 4a, 4b are each moved by a guide system 5 between a first position in which the door leaves 3a, 3b; 4a, 4b are aligned essentially coplanar to one another, and a second position in which the door leaves 3a, 3b; 4a, 4b are aligned essentially parallel to each other, movably mounted. The door leaves 3a, 3b can be inserted into a side receiving compartment 8a of the furniture body 2 in the second (parallel) position, while the other door leaves 4a, 4b can be inserted into a further receiving compartment 8b in a parallel position to one another. The functionality is explained below using the door leaves 3a and 3b, with the same explanations valid for the other door leaves 4a, 4b. The guide system 5 comprises a first guide rail 7a with a longitudinal direction (L), with a guide carriage 6 which can be connected to the second door leaf 3b being mounted movably along the first guide rail 7a.

Fig. 1b shows the furniture 1, with the door leaves 3a, 3b starting from the in Fig. 1a shown coplanar position were moved into an angular position to each other. The first door leaf 3a is mounted on a support 11 via three or more furniture hinges 10, which can be inserted into the receiving compartment 8a in a depth direction (Z). In the figure shown, the carrier 11 is in a transfer position in which the carrier 11 connects to the first guide rail 7a in the longitudinal direction (L), so that the guide carriage 6 can be transferred back and forth between the first guide rail 7a and the carrier 11. In the transfer position shown, the carrier 11 is releasably locked to the first guide rail 7a, the locking between the first guide rail 7a and the carrier 11 being releasable by the guide carriage 6 entering or onto the carrier 11. The carrier 11 is designed in the form of an elongated column, the length of which corresponds to at least half the height of the door leaves 3a, 3b. The two door leaves 3a, 3b are connected to one another in an articulated manner about a vertical axis via at least one hinge fitting 9. The second door leaf 3b is mounted so that it can move along the first guide rail 7a via the guide carriage 6.

Fig. 2a shows the furniture 1 with the door leaves 3a and 3b, which are now aligned parallel to each other. The carrier 11 was unlocked by an entry of the guide carriage 6 from the first guide rail 7a, so that the carrier 11 (together with the guide carriage 6 and the door leaves 3a, 3b) transversely in the depth direction (Z), along a path (not shown here). The second guide rail 7b of the guide system 5, which runs in the longitudinal direction (L), can be inserted into the receiving compartment 8a.

Fig. 2b shows the furniture 1 with the door leaves 3a, 3b, which are now in a fully inserted state in the receiving compartment 8a. The door leaves 3a, 3b are therefore guided by the guide system 5, starting from a first position Fig. 1a , in which the door leaves 3a, 3b are aligned essentially coplanar to one another, and according to a second position Fig. 2b , in which the door leaves 3a, 3b are aligned essentially parallel to one another and can be received within the receiving compartment 8a, movably mounted. In this way, for example, one like in the Figures 2a, 2b Kitchen 12 shown can be completely covered, so that the kitchen 12 can be visually separated from the remaining area of a living room. In the exemplary embodiment shown, the receiving compartment 8a is formed by a side wall 13a and a fixed furniture part 13b spaced parallel to the side wall 13a, the two door leaves 3a, 3b being able to be inserted in a parallel position to one another between the side wall 13a and the fixed furniture part 13b.

Fig. 3 shows a perspective view of the guide system 5 in the area between the side wall 13a and the fixed furniture part 13b, between which the receiving compartment 8a is formed for receiving the door leaves 3a, 3b. The first guide rail 7a has a longitudinal direction (L), which runs parallel to a front edge of the furniture body 2 in an assembly position. A second guide rail 7b with a longitudinal direction (L2) is arranged on the fixed furniture part 13b, the longitudinal direction (L) of the first guide rail 7a and the longitudinal direction (L2) of the second guide rail 7b extending transversely, preferably essentially at right angles, to one another. The carrier 11 is designed to movably support the at least one door leaf 3a, with the door leaf 3a in an assembled state having at least three or more furniture hinges 10 ( Fig. 1b ) is pivotally mounted on the carrier 11 about an axis that runs vertically in the installed position. The carrier 11 has at least one guide device 14, through which the carrier 11 can be moved along the second guide rail 7b in the depth direction (Z) and in a direction opposite to the depth direction (Z). In the figure shown, the guide device 14 of the carrier 11 has at least one roller 14a, which is movably mounted along a first catwalk 17a of the second guide rail 7b.

In the exemplary embodiment shown, the carrier 11 can be releasably locked to the first guide rail 7a via a receiving device 15. The receiving device 15 is designed to receive the movable guide carriage 6, so that the guide carriage 6 can be moved into the receiving device 15 starting from the first guide rail 7a. For this purpose, guide grooves 20, 21 can be formed in the first guide rail 7a, which extend in the longitudinal direction (L) of the first guide rail 7a and which, in the transfer position of the receiving device 15, are aligned with corresponding guide grooves 20a, 21a of the receiving device 15. In this way, the rollers of the guide carriage 6 can be moved without a disturbing abutting edge between the first guide rail 7a and the receiving device 15.

For improved decoupling between the receiving device 15 and the carrier 11, it can be provided that the receiving device 15 has at least one support roller 34 that is separate from the guide device 14 of the carrier 11 is mounted movably along the second guide rail 7b. It is preferably provided that the second guide rail 7b has a first catwalk 17a and at least one second catwalk 17b separate from the first catwalk 17a, with the roller 14a of the guide device 14 running along the first catwalk 17a of the second guide rail 7b and the at least one support roller 34 of the receiving device 15 is movably mounted along the second catwalk 17b of the second guide rail 7b.

The carrier 11 and the receiving device 15 are connected to one another in a movement-coupled manner when moving along the second guide rail 7b in the depth direction (Z), it being preferably provided that the receiving device 15 moves along the second guide rail 7b in the depth direction (Z) and are coupled together without play in a direction opposite to the depth direction (Z). For improved support of the carrier 11, at least one further guide rail 7c is provided, along which at least one further roller 19 of the carrier 11 is movably mounted.

Fig. 4 shows a perspective view of the door leaf 3a, on which a mounting part 16 is pre-assembled for attachment to the carrier 11. At least three (in this case five) furniture hinges 10 are arranged on the mounting part 16 for the pivotable mounting of the door leaf 3a. In the figure shown, the mounting part 16 can be designed as a rail running in the longitudinal direction (L1) of the carrier 11, which can be designed in one piece or in several parts. The mounting part 16 can be releasably connected to the carrier 11 in a direction transverse to the longitudinal direction (L1) of the carrier 11, preferably by hanging.

The mounting part 16 has at least one flat contact surface 16a, which in a connected state with the carrier 11 rests on a flat contact surface 11a of the carrier 11. By means of at least one adjusting device 35a, 35b, which is designed separately from the furniture hinges 10, a position of the mounting part 16 relative to the carrier 11 can be adjusted in the connected state. It is preferably provided that a position of the mounting part 16 relative to the carrier 11 in a lateral direction (X) and in a height direction (H) can be adjusted by the upper adjustment device 35a, whereas by the lower one Adjusting device 35b only one position of the mounting part 16 can be adjusted relative to the carrier 11 in a lateral direction (X).

The mounting part 16 can be fastened to the carrier 11 by at least one fastening device 18a, 18b. In the exemplary embodiment shown, the fastening devices 18a, 18b each have at least one projection 19a, 19b ( Fig. 5 ), which engage in a corresponding recess 36a, 36b of the mounting part 16 when the mounting part 16 is connected. According to an exemplary embodiment, it can be provided that the projections 19a, 19b of the fastening devices 18a, 18b cooperate with the adjusting devices 35a, 35b of the mounting part 16, so that a position of the mounting part 16 relative to the carrier 11 via the projections 19a, 19b of the fastening devices 18a, 18b is brought about. When the mounting part 16 is connected, the carrier 11 (together with the mounting part 16 and the door leaf 3a fastened via the furniture hinges 10) can be moved along the second guide rail 7b in the depth direction (Z) and in a direction opposite to the depth direction (Z). In the figure shown, the further guide rail 7c is arranged in an area near the floor of the fixed furniture part 13b.

Fig. 5 shows the assembly part 16 with the furniture hinges 10 and the adjusting devices 35a, 35b in an exploded view. The mounting part 16 can be designed as a rail extending in the longitudinal direction (L1), with the furniture hinges 10 being spaced apart from one another in the longitudinal direction (L1) in a fastened state. The furniture hinges 10 each have a first fitting part 10a for attachment to the mounting part 16 and a second fitting part 10b for attachment to the door leaf 3a, the first fitting part 10a and the second fitting part 10b being pivotally connected to one another via at least one joint axis, preferably over at least five joint axes are. The first fitting parts 10a of the furniture hinges 10 are either screwed to the mounting part 16 or can be releasably locked to the mounting part 16. The fastening devices 18a, 18b each have a projection 19a, 19b arranged on the carrier 11, which engage in corresponding recesses 36a, 36b of the mounting part 16 when the mounting part 16 is connected to the carrier 11. The projections 19a, 19b can each cooperate with the adjusting devices 35a, 35b, so that a position of the mounting part 16 relative to the carrier 11 is adjusted by actuating the adjusting devices 35a, 35b, through which a relative position between the mounting part 16 and the projections 19a, 19b can be changed.

Fig. 6 shows the mounting part 16 to be attached to the carrier 11, on which the furniture hinges 10 are arranged for movable mounting of the door leaf 3a. For fastening, the mounting part 16 is guided with its flat contact surface 16a against the flat contact surface 11a of the carrier 11, the projection 19a of the carrier 11 engaging in the corresponding recess 36a of the mounting part 16. The projection 19a inserted into the recess 36a cooperates with the adjusting device 35a, which is attached to the mounting part 16 via a holder 23. To fix the mounting part 16, at least one or more fastening screws 26 can be used, which engage in an elongated hole 27 of the carrier 11 in the mounted state. However, so that the mounting part 16 remains adjustable in a connected state relative to the carrier 11, the fastening screws 26 can, for example, have a recess, whereby the mounting part 16 is arranged with radial play relative to the fastening screw 26 - despite the fastening screw 26 being tightened.

Fig. 7a shows the projection 19a of the fastening device 18a to be fastened to the carrier 11 in a released state on the adjusting device 35a, which is to be connected to the mounting part 16 via the holder 23. The projection 19a has at least one trough 37 for holding the mounting part 16, the projection 19a being insertable into an insertion opening 22 of the adjusting device 35a.

Fig. 7b shows the attached state of the projection 19a on the adjusting device 35a, with a component of the adjusting device 35a being accommodated in the trough 37. The adjusting device 35a has a height adjustment 24, through which the holder 23 (and thus the mounting part 16) can be adjusted in a height direction (H) in the assembled state, whereby the door leaf 3a can also be adjusted in the height direction (H) relative to the carrier 11. In addition, a side adjustment 25 is provided, through which the holder 23 (and thus the mounting part 16) in the assembled state in one lateral direction (X) is adjustable, whereby the door leaf 3a is also adjustable in the lateral direction (X) relative to the carrier 11.

Fig. 8a shows the adjustment device 35a in a cross section, from which the height adjustment 24 and the side adjustment 25 ( Fig. 8b ) for adjusting the mounting part 16 relative to the carrier 11. The holder 23 of the adjusting device 35a is to be firmly connected to the mounting part 16 via at least one fastening means 31 (for example a screw). The projection 19a arranged on the carrier 11 interacts via the trough 37 with a first adjustment part 29a, which is mounted within a second adjustment part 29b and which is adjustable in the lateral direction (X) relative to the second adjustment part 29b. The second adjustment part 29b is adjustable (together with the first adjustment part 29a) in the height direction (H).

The height adjustment 24 comprises an adjustment wheel 28a, which in an assembled state is rotatably mounted about a vertical axis of rotation, which is in threaded engagement with the second adjustment part 29b and which is supported on a bolt 30c of the second adjustment part 29b. By rotating the adjusting wheel 28a, the second adjusting part 29b (together with the first adjusting part 29a) can be adjusted relative to the holder 23 in the height direction (H), so that all of the furniture hinges 10 provided for supporting the door leaf 3a and arranged on the mounting part 16 are also in the Height direction (H) can be adjusted synchronously relative to the carrier 11.

Fig. 8b shows the lateral adjustment 25 of the mounting part 16 relative to the carrier 11. The first adjustment part 29a can be adjusted in the lateral direction (X) relative to the second adjustment part 29b by at least one linear guide 30. In the exemplary embodiment shown, the linear guide 38 comprises two, preferably cylindrical, bolts 30a, 30b for guiding the first adjustment part 29a in the lateral direction (X). The side adjustment 25 comprises a rotatably mounted adjustment wheel 28b, which in an assembled state is rotatably mounted about a horizontally extending axis of rotation and which is in threaded engagement with the first adjustment part 29a. By rotating the adjusting wheel 28b, the first adjusting part 29a can be adjusted relative to the second adjusting part 29b in the lateral direction (X), so that all of the elements for supporting the door leaf are also adjustable 3a provided and arranged on the mounting part 16 furniture hinges 10 can be synchronously adjusted in the lateral direction (X) relative to the carrier 11.

The setting wheels 28a, 28b shown can each have a tool holder 24a, the setting wheels 28a, 28b being adjustable by rotating the tool holder 24a using a tool. Alternatively, it is possible for the height adjustment 24 and/or the side adjustment 25 to have or have at least one drive element with a tool holder 24a that is separate from the adjustment wheels 28a, 28b and is motion-coupled to the adjustment wheels 28a, 28b.

Fig. 9 shows the adjustment device 35a in an exploded view. The holder 23 is to be fastened to the mounting part 16 via the at least one fastening means 31 and has a further linear guide 32, through which the second adjusting part 29b can be adjusted relative to the holder 23 by rotating the adjusting wheel 28a in the height direction (H). The first adjustment part 29a with the insertion opening 22 for inserting the projection 19a is mounted displaceably in the lateral direction (X) within the second adjustment part 29b by rotating the adjustment wheel 28b along the two bolts 30a, 30b of the linear guide 30. The setting wheel 28a is accommodated between two housing parts 33a, 33b, the setting wheel 28a being drivable by the tool holder 24a which is separate from the setting wheel 28a. The axis of rotation of the adjusting wheel 28a and the axis of rotation of the tool holder 24a run transversely to one another, which, in addition to improved accessibility, also offers the possibility of changing a gear ratio.

Fig. 10a shows an exemplary possibility for attaching a furniture hinge 10 to the mounting part 16. The mounting part 16 has at least one linear guide 38a, 38b, which extends at least in sections in the longitudinal direction (L1) of the mounting part 16. However, it is also possible for the at least one linear guide 38a, 38b to extend transversely to the longitudinal direction (L1) of the mounting part 16. The furniture hinge 10 has a first fitting part 10a for attachment to the mounting part 16 and a fitting part 10b which is articulated to the first fitting part 10a for attachment to the door leaf 3a. The first fitting part 10a and the second fitting part 10b can have at least five, preferably at least seven, joint axes (A, B, C, D, E, F, G) must be connected to each other, as in Fig. 11b is shown.

The furniture hinge 10 has at least one positive connection 39a, 39b, which interacts with the at least one linear guide 38a, 38b of the mounting part 16. In the exemplary embodiment shown, the furniture hinge 10 can be pushed onto the linear guides 38a, 38b of the mounting part 16 via the positive connections 39a, 39b and can be moved in the longitudinal direction (L1) of the mounting part 16. This offers, for example, the possibility of first attaching the furniture hinges 10 to the door leaf 3a in a first assembly step. In a second assembly step, the furniture hinges 10 pre-assembled on the door leaf 3a are pushed onto the assembly part 16 and thus obtain their exact position on the assembly part 16. In this way, easy and quick assembly of the furniture hinges 10 can be made possible and unwanted tensioning of the furniture hinges on the assembly part 16 can be prevented . By means of a locking element 40 arranged on the mounting part 16 and/or on at least one of the furniture hinges 10 ( Fig. 11a ), the furniture hinge 10 can be secured to the mounting part 16, preferably by clamping. Fig. 10b shows the connected state of the furniture hinge 10 on the mounting part 16.

Fig. 11a shows the furniture hinge 10 arranged on the mounting part 16 in a cross-sectional view. The positive connections 39a, 39b of the furniture hinge 10 interact with the linear guides 38a, 38b of the mounting part 16. The position of the furniture hinge 10 in relation to the mounting part 16 can be determined, preferably by clamping, by at least one locking element 40.
