[0001] COMPENSATION SYSTEM FOR THE INTERLOCKING APPLICATION

[0002] OF A COVER STRIP BETWEEN A FRAME AND THE WALL RECESS

[0003] THAT CONTAINS IT

[0005] The present invention concerns a compensation system for the application of a cover strip applicable to the internal part of any frame , which, through the interlocking overlapping of two specially designed profiles , allows to fill the gap between the face of the frame and the wall of the recess in which the frame is installed, thereby extending the frame length and providing an aesthetically pleasing appearance to the frame , its casing, and the entire wall recess .

[0006] As is well known, the installation of window and door frames generally involves the mounting, along their perimeter, of a frame that can be finished with cover strips , as in the present case , when there is a distance between the frame and the wall recess in which it is installed .

[0007] The cover strips are slats of variable width depending on the needs , generally made of the same material as the frame , whose function is not merely aesthetic . In fact , the cover strips serve to frame the window frame , adapting to and covering the wall and its irregularities , the space between frame and wall , and, in particular, the space between the frame and the reveals and / or head of the opening, thereby providing a finished appearance to the frame installation and covering possible imperfections at the edges and j oints between the frame and the wall .

[0008] In situations where there is a considerable distance between the frame and the wall of the recess , the cover strips help to even out and improve the final aesthetic appearance of the installation . The cover strips also perform a protective function, covering the masonry j oint to which the frame is fixed . They protect the visible parts of the structure and hide polyurethane foam used for sealing, as well as the typical sel f-expanding sealing tape for window frames , which prevents water ingress and condensation phenomena that may occur near the coldest points of the frames and j oints .

[0009] Cover strips may be cut and made from various materials depending on requirements and are normally positioned and glued onto the frames . This procedure naturally entails issues concerning adhesion to counter- frames , surfaces , and adhesives used .

[0010] To avoid installation problems related to gluing, various alternative solutions have been developed over time and disclosed in prior industrial property titles .

[0011] Patent IT101998900653153 , applicable only to doors , describes a locking system of an L-shaped cover strip to its frame us ing an elastic pressure element , made of rubber or another material , fixed to the frame itsel f , which must be equipped with special slots . As can be easily imagined, such a system, besides being limited to doors , requires specially manufactured frames with slots to receive the elastic element and provides poor performance in terms of application and retention .

[0012] Other patents attempt to solve technical problems related to the mounting of cover strips by using di f ferent anchoring systems . For instance , patent IT201995900463958 describes an anchoring system consisting of a male insert placed in a hole inside the cover strip and a female insert placed in a corresponding hole in the frame , which engage with each other once overlapped .

[0013] Patent IT202008901690903 , which is rather obvious in its implementation, describes a cover strip for a door j amb having two proj ections that define a sliding groove suitable for guiding and retaining an insert within the cover strip .

[0014] Finally, patent IT202004901196080 discloses a complex and hardly reali zable system describing a particular frame structure in which, to achieve a compensating cover strip, the profiles of the frame must have speci fic structural features , including hooks , stops , and elastic profiles integrated with each other .

[0015] Conventional cover strip systems generally rely on adhesives , elastic inserts , or frame-speci fic profiles that require machining or pre-designed slots . These approaches lead to poor adaptability to di f ferent frame types and to tolerance issues during installation .

[0016] The purpose of the present invention is to overcome the drawbacks of the prior art by providing a compensation interlocking system for applying a cover strip between the inner part of a frame and the wall recess that contains it , which is simple and cost- ef fective to produce , easy to install , applicable to any type of frame , without the use of adhesives , and without interfering with the face of the frame itsel f . In this way, the frame , after applying the system, appears uni form and completely covers the wall recess , ensuring tolerance compensation for varying wall gaps without the need of additional machining or elastic parts .

[0017] The system achieves a stable mechanical coupling by means of a snap- fit engagement between the two profiles , providing consistent retention force over time even under thermal expansion or material deformation .

[0018] In this way, the frame , after applying the system, appears uni form and completely covers the wall recess .

[0019] The present invention will now be described, purely by way of non-limiting example , with reference to the attached figures and drawings . It is understood that all embodiments may vary in dimensions , number, and shape without limiting the scope of protection of the present model .

[0020] Figure 1 shows a sectional view of the system in a first embodiment .

[0021] Figure 2 shows a sectional view of the assembled system in the first embodiment .

[0022] Figure 3 shows a perspective view of the system .

[0023] Figure 4 shows a perspective view of the assembled system . Figure 5 shows the anchoring base of the system screwed onto the frame.

[0024] Figure 6 shows the installed and assembled system.

[0025] Figure 7 shows a second embodiment of the system, particularly of the anchoring profile, for cases where the distance between the frame and the wall recess is limited .

[0026] With reference to the figures described above, in its preferred embodiments, the system comprises a U- shaped anchoring profile (101) having a base (102) provided with at least one through hole (103) , which may be positioned at any point on the base to allow the passage of threaded screws (Y) through which the support is fixed onto the frame (X) , and two side walls (104, 105) provided with outwardly facing hooking edges (106) .

[0027] The base (102) with the two side walls (104, 105) thus define a coupling groove (107) .

[0028] In a first embodiment, once the anchoring profile (101) has been fixed onto the frame (X) with screws (Y) , a cover strip profile (108) is interlocked onto it through a snap-fit system. The cover strip profile (108) comprises a base (109) of variable length according to the space to be covered between the frame and the wall recess.

[0029] The profile (108) includes two side walls (110, 111) forming a retaining groove (112) with inwardly facing hooking edges (113) which, during assembly, engage with the hooking edges (106) on the side walls (104, 105) of the anchoring profile (101) , forming a single integrated block.

[0030] In this embodiment, the cover strip profile (108) also comprises a wall portion (114) extending along the base (109) to fill the distance between the frame (X) and the masonry recess (Z) , thereby covering the visible wall area.

[0031] In a second embodiment, where the distance between the frame (X) and the wall recess (Z) is very small, the cover strip profile (108) consists only of the two side walls (110, 111) and is interlocked directly onto the anchoring profile (101) .

[0032] In a preferred installation mode, the user can easily assemble the system by first drilling a hole in the frame, inserting the screw (Y) through the through hole (103) of the anchoring profile (101) , and subsequently interlocking the cover strip profile (108) onto the anchoring profile (101) .

[0033] Compared to known systems, the invention thus provides a robust and versatile interlocking mechanism that can be industrially applied without the need for frame redesign, adhesives , or elastic j oints , thereby simpli fying production and installation processes .

[0034] The present invention has been described with reference to its functional features for illustrative but not limiting purposes . It is therefore understood that the described system may be subj ect to minor variations and / or modi fications without departing from the scope of protection defined by the accompanying claims .
