AI Technical Summary
Existing guide systems for sliding windows and doors are exposed to external influences, leading to mechanical stress, wear, and functional issues due to visibility and exposure to weather and accidental impacts.
A guide system is recessed within the fixed structure and cover element, with guide rails sunk into the cover element and the fixed structure, ensuring protection from external influences and maintaining a minimalist design.
The guide system is shielded from environmental factors and potential collisions, extending its functionality and maintenance intervals while reducing the risk of injury and enhancing aesthetic and functional design.

Abstract
Description
[0001] Arrangement with structure, cover element and guide system
[0002] The present invention relates to an arrangement with a
[0003] Guidance system according to the features of the preamble of the claim
[0004] 1 .
[0005] Such arrangements are generally used to move a covering element, such as a window, a door or a drawer front, relative to a fixed structure, such as a building wall or a furniture body.
[0006] Particularly in the case of windows or doors, the movement comprises a lateral displacement of the cover element relative to the fixed structure. Such sliding windows or doors, which in particular enable the fixed structure to be fully opened, are also known, for example, from car sliding doors. In such solutions, the guide systems that allow the relative displacement between a cover element and the fixed structure are usually located on an outer side of the structure, e.g., the car or building, since the cover element would only be a hindrance if it were open inside the structure.
[0007] The disadvantage here is that at least parts of the guide system are often constantly visible from the outside, protrude in a disruptive manner, and are unfavorably exposed to environmental influences. This means that the guide system is increasingly exposed to mechanical stress, e.g., from accidental impacts or jamming, and to the elements, particularly moisture, frost, thermal deformation, etc., which in turn can lead to increased wear or functional problems.
[0008] The object of the present invention is therefore to provide an arrangement with a guide system, wherein the guide system is protected from any external influences, in particular in a closed position of the cover element.
[0009] This object is achieved by the features of claim 1, namely by an arrangement with a fixed structure, at least one cover element and at least one guide system for guiding a movement of the cover element relative to the fixed structure, wherein the guide system comprises a first guide rail which is fastened or can be fastened to, preferably a pole, of the fixed structure and at least one second guide rail which is fastened or can be fastened to at least one cover element and which is movable relative to the first guide rail, wherein the second guide rail is arranged or can be arranged countersunk in the cover element and the first guide rail is arranged or can be arranged countersunk, preferably in the pole, in the fixed structure.
[0010] A first major advantage of the invention is that the guide system is protected by other components of the assembly and is thus hardly exposed to external influences. On the one hand, the guide system is significantly less exposed to the elements, especially snow, moisture, or extreme temperatures; on the other hand, it is protected from accidental impacts or jamming. Consequently, its functionality and any maintenance intervals can be significantly extended.
[0011] In connection with unintentional collisions or jamming, a reduced risk of injury to operators or passers-by can also be seen as an advantage.
[0012] A further advantage is that the recessed arrangement of the guide system allows for a visually and functionally minimalist design, so that the proposed guide system can serve as a technical basis for a range of applications in building construction. For example, the guide system can be used for windows, doors, cladding, partition, and / or facade elements.
[0013] A cover element is not necessarily to be understood as an element with the purpose of covering an opening or another element, but can also have a dimming, separating, protective or similar function.
[0014] The cover element can have any shape, design or construction, i.e. it can be solid, grid-like, completely or partially flat, with or without a frame and / or have any material properties and / or surface characteristics.
[0015] In a particularly preferred variant, the covering element is a window and / or a door which is intended for a window and / or door opening of a building.
[0016] In principle, the arrangement may comprise one or more fixed structures, covering elements and / or guide systems.
[0017] Further advantageous embodiments of the invention are defined in the dependent claims.
[0018] It is particularly preferably provided that the guide system is arranged sunk in the fixed structure and in the cover element in a closed position of the cover element, in particular so that the guide system is substantially completely enclosed by the fixed structure and the cover element.

[0020] It is preferably provided that the first guide rail and the second guide rail, in the closed position and / or the parked open position of the cover element, lie substantially congruently with one another in a view orthogonal to the cover element, preferably orthogonal to a central surface of the cover element. This is particularly advantageous if the cover element is a window or a door and the fixed structure is a building.
