Description

Guide system for guiding at least one movably mounted door leaf along a furniture wall The present invention relates to a guide system for guiding at least one movably mounted door leaf along a furniture wall, comprising: - a first guide rail to be attached to the furniture wall, - at least one second guide rail to be fixed to the furniture wall at a vertical distance from the first guide rail, - a support for pivotably supporting at least one door leaf, - at least one first guide device by which the carrier is movably mounted along the first guide rail, - at least one second guide device by which the carrier is movably mounted along the second guide rail, - a cable pulling device for compensating a tilting moment of the beam about a tilting axis by a restoring moment. Such guide systems are usually used to guide at least one door leaf, which can be inserted in a depth direction of the furniture along a furniture wall into a furniture body or into a receiving compartment located laterally next to the furniture body. A particular challenge in guiding such a door leaf is that the door leaf tends to tilt due to the force of its weight. Such tilting of the door leaf also leads to a slanting position of the support and to a tilting of the two guide devices, whereby the guide devices with their assigned Guide rails can jam. In the event of such a jam, movement of the door leaf is impossible or at least significantly hampered. A primary goal is therefore to ensure that the two guide devices are guided relative to their assigned guide rails in a way that is largely secure against jamming. Guide systems for a door leaf with a cable pull device for tilt-free guidance of a door leaf are shown, for example, in US 2007/0159037A1 (Fig. 4), in WO 2018/129568 A1 (Fig. 5a), in DE 197 09 461 A1 (Fig. 5), in EP 1 394 349 A1 (Fig. 1), and in EP 0 128 503 A1 (Fig. 3). To improve the stability of the two guide devices relative to one another, a crosswise cable guide is advantageous, for which at least two cables are provided. However, the installation of two cables is complicated for an installer and also involves increased component complexity. The object of the present invention is to provide a guidance system of the type mentioned at the outset 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 present invention are defined in the dependent claims. According to the invention, it is provided that the cable pulling device has at least one, preferably exactly one, cable, wherein the cable is guided crosswise over at least two deflection pulleys arranged on the two guide devices and/or on the at least one carrier. The state of the art mentioned at the beginning does indeed provide for a crosswise cable guide, but at least two Ropes are required. In the present invention, however, a single rope is generally sufficient to form a cross in the rope guide. This significantly simplifies the assembly of the rope pulling device. The piece of furniture according to the invention comprises a furniture body, at least one door leaf movable relative to the furniture body and at least one guide system of the type in question. Further details and advantages of the present invention will become apparent from the following description of the figures. Fig. 1a, 1b show a perspective view of a piece of furniture with a furniture body and door leaves movable relative thereto, Fig. 2a, 2b show the furniture according to Figures 1a, 1b in further positions of the door leaves relative to each other, Fig. 3 shows the guide system in a perspective view, Fig. 4 shows the guide system in a schematic side view, Fig. 5 shows the guide system with the cable pulling device in a schematic side view, Fig. 6a, 6b show the cable pulling device in a perspective view and an enlarged detailed view thereof, Fig. 7a, 7b show the cable pulling device in a further perspective view as well as an enlarged detailed view thereof, Fig. 8a, 8b show two different embodiments of an inclination adjustment device by means of which an inclination of the carrier relative to a vertical can be adjusted. Fig. 1a shows a perspective view of a piece of furniture 1 with a furniture body 2 and at least one door leaf 3a, 3b; 4a, 4b mounted so as to be movable relative to the furniture body 2. In the illustrated embodiment, a folding-sliding door is provided, with the door leaf 3a and the door leaf 3b being hinged together via a vertically extending first pivot axis. The other two door leaves 4a, 4b are hinged together via a vertically extending second pivot axis. The door leaves 3a, 3b and the door leaves 4a, 4b are each movable by a guide system 5 between a first position in which the door leaves 3a, 3b; 4a, 4b are aligned substantially coplanar to one another, and a second position in which the door leaves 3a, 3b; 4a, 4b are aligned substantially parallel to one another.
