Description

[0001] guidance system

[0002] The present invention relates to a guidance system according to the features of the preamble of claim 1.

[0003] Furthermore, the invention relates to an arrangement with a fixed structure, at least one cover element and at least one guide system and a method for moving at least one cover element by means of such a guide system.

[0004] Such guide systems are generally used to move a covering element, such as a window or a door, relative to a fixed structure, such as a building wall, wherein the movement usually comprises a lateral displacement of the covering element relative to the fixed structure.

[0005] Applications for this include conventional sliding windows or doors with frames and frames, wherein the movable cover element, e.g., the sliding window pane, is enclosed in the frame, and the frame can be moved laterally along and within the frame inserted in the window or door opening. Such a sliding window or sliding door often comprises at least two cover elements, with at least one movable cover element being able to be moved over a second cover element. The frames of the cover elements are always located essentially within the frame or within its plane, so that the sliding movement of the cover element is limited by the frame or the opening.

[0006] The disadvantage here is that the window or door opening is always covered by at least one covering element, meaning that only a portion of the window or door opening is exposed. The object of the present invention is to provide a guide system that is more advantageous than the prior art and that makes it possible to completely or largely expose an opening in a fixed structure.

[0007] This object is achieved by the features of claim 1, namely by a guide system for guiding at least one cover element which is movable relative to a fixed structure, wherein the guide system comprises at least one first guide rail to be fastened to the fixed structure and at least one second guide rail to be fastened to the at least one cover element, which second guide rail is movable relative to the at least one first guide rail, wherein the at least one second guide rail is arranged in at least one operating position, preferably in all operating positions, completely outside a construction space of the at least one first guide rail.

[0008] In other words, the first guide rail and the second guide rail are spaced apart from one another or are not nested or do not overlap or engage with one another.

[0009] A first major advantage of the invention, or rather the spaced-apart arrangement of the second guide rail relative to the first guide rail, is that the cover element can be moved such that an opening in the fixed structure can be completely exposed. This means that the cover element can be moved at a distance over a fixed structure. Its movement is therefore not limited by the pole or the opening dimensions.

[0010] A further advantage, particularly in the case where the cover element is or comprises a window or door, is that a window or door opening can be opened in an orthogonal position without completely exposing the opening. For example, such an orthogonally positioned opening of the cover element can be practical for ventilating a building while the opening is to remain blocked and / or inaccessible.

[0011] Further advantageous embodiments of the invention are defined in the dependent claims.

[0012] It is particularly preferably provided that a distance between the at least one first guide rail and the at least one second guide rail is variable, wherein the distance is preferably substantially constant along a longitudinal axis of the first guide rail and / or the second guide rail, so that the first guide rail and the second guide rail are aligned substantially parallel to one another.

[0013] The variation of the, in particular orthogonal, distance between the first guide rail or the installation space of the first guide rail and the second guide rail or the installation space of the second guide rail can be changed in particular by moving the cover element.

[0014] It is particularly preferably provided that the operating positions of the guide system comprise a first operating position, which corresponds to a closed position of the cover element, and a second operating position, which corresponds to an essentially, preferably outwardly, orthogonally positioned open position of the cover element, and / or a third operating position, which corresponds to an essentially completely open position of the cover element, in particular a laterally shifted one.

[0015] It is preferably provided that the first guide rail and the second guide rail are further apart from one another in the second operating position and / or the third operating position than in the first operating position, preferably wherein the distance in the first operating position is a minimum distance and / or in the second operating position and / or in the third operating position is a maximum distance.

[0016] It is preferably provided that the distance in the second operating position and / or the third operating position is between 50 mm and 200 mm, particularly preferably between 100 mm and 150 mm.

[0018] Conversely, this means that the first guide rail and the second guide rail in the first operating position or the closed position and / or the parked open position of the cover element are arranged next to one another in a view, in particular orthogonal to the cover element, essentially congruently.

[0019] In particularly preferred embodiments, the first guide rail and the second guide rail are connected to one another by at least one articulated lever mechanism, preferably by at least two articulated lever mechanisms, such that they can move relative to one another, in particular wherein the second guide rail is suspended from the first guide rail by means of the articulated lever mechanism.

[0022] It is preferably provided that the at least one articulated lever mechanism is mounted, preferably by means of at least one groove, in a rotationally positive manner and in a translationally displaceable manner along a longitudinal direction of the first guide rail and / or the second guide rail, in particular during a movement of the guide system between the second operating position and the third operating position.

[0023] It is preferably provided that the guide system has at least two support levers which are articulated to one another via a first joint axis and which two support levers each form a support toggle lever, and at least two drive levers which are articulated to one another via a second joint axis and which two drive levers each form a drive toggle lever, preferably wherein the first joint axis and the second joint axis run substantially orthogonally to one another.

[0024] It can be provided that the guide system has at least one synchronization device for synchronizing a movement of at least two drive toggle levers, preferably, which synchronization device is arranged on the first guide rail and / or has at least one synchronization shaft and / or at least one cable pull.

[0025] In preferred embodiments, the guide system is designed to hold a cover element in a freely projecting manner by means of at least four support toggle levers, in particular wherein two of the four support toggle levers are spaced apart from one another at a minimum support lever distance along the longitudinal direction of the first guide rail and / or the second guide rail.

[0026] The minimum support lever distance can be understood, for example, as the distance between two support toggle levers which just allows stable holding of the freely projecting cover element, in particular supported by at least one tilting moment compensation device.

[0027] Furthermore, protection is sought for an arrangement with a fixed structure, at least one cover element and at least one guide system according to the invention, or variants thereof, preferably wherein the at least one, in particular substantially square, cover element has two substantially horizontal outer edges and / or frame sections, along each of which at least one guide system is arranged.

[0032] In principle, it is also possible for the cover element to have edges and / or strips at least in some areas, which are stiffened together, e.g. by means of discs and / or struts.

[0033] Protection is also sought for a method for moving at least one cover element relative to a fixed structure by means of at least one guide system according to the invention, or variants thereof, wherein the at least one cover element is moved, in particular by moving the cover element, between at least two operating positions. Particularly preferably, the method comprises steps,
