Description

Guide system for guiding at least one movably mounted door leaf The present invention relates to a guide system for guiding at least one movably mounted door leaf, comprising: - at least one first guide rail with a longitudinal direction for guiding the at least one door leaf, - at least one carriage which can be connected to the at least one door leaf and which is mounted so as to be movable along the first guide rail, - at least one support on which the at least one carriage can be arranged, wherein the support is movable along at least one second guide rail, wherein the at least one second guide rail runs transversely to the longitudinal direction of the first guide rail, wherein the support is movable in an assembly position into a transfer position in which the support adjoins the at least one first guide rail in the longitudinal direction, so that the carriage can be transferred back and forth between the at least one first guide rail and the support. Furthermore, the invention relates to a piece of furniture with a furniture body, at least one door leaf movable relative to the furniture body, and with at least one guide system of the type to be described for guiding the at least one door leaf relative to the furniture body. WO 2020/097656 A1 shows a guide system for guiding door leaves, wherein the door leaves are movable by the guide system between a first position, in which the door leaves are arranged substantially coplanar to one another, and a second position, in which the door leaves are arranged substantially parallel to one another. For an improved transition of the door leaves between the coplanar position and the parallel position, a curved control contour is provided, along which a roller of a carriage connectable to a door leaf can be moved. The curved control contour is arranged on an end region of a first guide rail which is to be arranged parallel to an end face of the furniture body. The control contour is formed integrally with the first guide rail or, alternatively, is arranged on an adapter piece that can be connected to the first guide rail. In addition, a second guide rail is provided, along which the two door leaves can be moved in a parallel position to one another in a depth direction of the furniture body. A disadvantage of the current technology is that the components of the guide system must be arranged on the first guide rail, the furniture body, and the support. This results in the difficulty that coordinating the components and assembling the guide system poses some challenges. A further disadvantage is that the carriage in the transition area between the two guide rails often does not have sufficient speed to allow for smooth and dynamic movement of the carriage in the transition area. This can result in the door leaf moving jerkily in the transition area and causing unpleasant noises. The object of the present invention is to provide a guide system which is improved over the prior art and which avoids the disadvantages discussed above. This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the present invention are defined in the dependent claims. According to the invention, it is provided that a deflection device is provided with at least one control cam, wherein the deflection device is designed to convert a movement of the at least one carrier along the at least one second guide rail into a movement of the carriage along the at least one first guide rail, wherein at least the control cam of the deflection device and the at least one second guide rail are arranged substantially in a common plane. In other words: a deflection device is provided which converts a movement of the carrier into a drive movement by means of which the carriage can be driven at least in sections along the first guide rail. If the carriage is moved in the opposite direction, i.e. from the first guide rail in the direction of the second guide rail, the deflection device converts a movement of the carriage into a drive movement by means of which the carrier can be driven at least in sections along the second guide rail. Furthermore, at least the control cam of the deflection device and the at least one second guide rail are arranged substantially one above the other in a common plane. In this way, the deflection device is associated with the second guide rail, so that mounting of the deflection device on the first guide rail is no longer necessary. The deflection device and the second guide rail can each be designed in some areas to be substantially plate-shaped or substantially cuboid-shaped, wherein at least the control cam of the deflection device and the second guide rail are arranged one above the other in a mounted state substantially in a common plane. The proposed invention makes it possible to pre-assemble the guide system essentially completely on the furniture, so that a perfect coordination of the components with each othe
