[0022] The detailed description that follows should therefore not be interpreted as limiting, and the scope of the present invention is defined by the attached claims.

[0023] The invention described herein relates to a cavity screen, which is a blind or vertical screen placed in front of a window or door of a dwelling to prevent sunlight from entering when necessary. The cavity screen is mounted within the cavity wall so that the installation is concealed and barely visible. Ideally, the housing of the cavity screen and the side guides are both concealed within the cavity wall of the house. Suitable materials such as woven textile, fiberglass or fabric, a plastic membrane or film, etc., are used for the screen.

[0024] In a first aspect, the present technology relates to a cavity screen comprising a protective box and two or more lateral guides, in which the protective box includes a screen roller and a screen that can be rolled onto this screen roller which is fixed to the latter on one of its sides and to which a lower slat is fixed on the opposite side, the bottom of the protective box further comprising a service hatch and a screen passage in which the latter is closed by the lower slat when the screen is rolled onto the screen roller;and where each of the side guides, which guide the lateral side of the screen when rolled up and unrolled, comprises a U-shaped base profile and an L-shaped outer profile, where the base profile is adapted to be fixed in the cavity, where the outer profile is fixed to the base profile at two points along the entire length of the side guide, and where the base profile and the outer profile together form the rectangular side guide.

[0025] As used herein, the term "protective housing" refers to the casing of a cavity screen housing the screen roll and a screen that can be wound and unwound onto said screen roll. The protective housing is preferably beam-shaped with a passage for the screen and a service hatch at the bottom, which is preferably hinged to open and provide access to the interior of the protective housing.

[0026] As used here, the term "lateral guide" refers to a guiding element that extends laterally from the protective housing. The lateral guide guides the side of the screen during rolling and unrolling. The cavity screen described here preferably comprises two lateral guides.

[0027] Each of the lateral guides preferably comprises two parts, namely a U-shaped base profile and an L-shaped outer profile. The U-shaped base profile The U-shaped profile is designed to be fixed within the cavity. The outer L-shaped profile attaches to the U-shaped base profile at two points along the entire length of the lateral guide. Together with the outer L-shaped profile, the U-shaped base profile forms the rectangular lateral guide.

[0028] Since the side guide consists of only two parts, it is easy to assemble and maintain. During assembly and disassembly, the U-shaped base profile is fixed in the hollow wall. The outer L-shaped profile is then attached to the U-shaped base profile. Because the side guide comprises only two profiles, installation is simple and physical adjustments to the profiles (shortening, for example) are also easy to make.

[0029] According to a particular embodiment, a cavity screen is described here in which the U-shaped basic profile includes a central section with two parallel protruding tabs on each side, in which the depth of the tabs is substantially the same and in which the width of the central section is longer than the depth of the tabs, and in which the L-shaped outer profile includes a long side whose width is shorter than the width of the central section of the U-shaped basic profile and includes a short side having substantially the same depth as the depth of the tabs of the U-shaped basic profile.

[0030] In other words, the U-shaped base profile consists of a central part and a projecting tab at each end. The two tabs are almost parallel to each other and protrude in the same direction. The projecting tabs are preferably almost perpendicular to the central section of the U-shaped base profile.

[0031] In other words, the L-shaped outer profile comprises a long side and a short side at one end. The short side has almost the same depth as the legs of the U-shaped base profile. The L-shaped outer profile is the visible part of the lateral guide.

[0032] Since the width of the long side of the outer L-shaped profile is less than the width of the central piece of the U-shaped base profile, a space is provided in the lateral guide to guide the lateral side of the screen during winding and unwinding.

[0033] According to a particular embodiment, here is the description of a cavity screen in which the width of the central piece of the U-shaped base profile is at least 2.5 and preferably at least 3.0 times longer than the depth of the leg.

[0034] According to a particular embodiment, here is the description of a cavity screen in which the long side of the L-shaped outer profile is at least 2.0 times longer than the depth of the short side of the L-shaped outer profile.

[0035] According to a particular embodiment, this is a description of a cavity screen in which the base profile and the outer profile form a space for a side profile into which the side of the screen slides. The space comprises An opening through which the screen can pass. One side edge of the screen can be held in place by this opening. The side edge of the screen is usually held by means of a side profile. This side profile extends into the space and has dimensions that prevent it from being pulled out of the space through the opening at the front of the screen. The side edge of the screen is held within the side profile, which is itself held within the space formed by the U-shaped base profile and the L-shaped outer profile. The side profile typically acts as a spring element, applying tension to the screen.

[0036] According to a particular embodiment, a cavity screen is described here in which the end of the first leg of the U-shaped base profile includes one or more notches and, preferably, a groove along the entire length of the side profile, adapted to receive the end of the long side of the L-shaped outer profile, and in which the end of the short side of the L-shaped outer profile is fixed to the central piece of the U-shaped base profile.

[0037] The presence of one or more notches or a groove along the entire length of the side guide ensures a secure and reliable attachment of the outer L-shaped profile to the U-shaped base profile. Furthermore, a connector between the first tab of the outer L-shaped profile and the end of the long side of the U-shaped base profile facilitates the assembly and disassembly of the side guide. By positioning the connector at this point, the two parts of the side guide can be connected and disconnected without the need to access the screen guide with tools. In the case of side guides, the space provided to guide the side of the screen during rolling and unrolling is crucial. Any damage to this part of the side guide will prevent the screen from rolling and unrolling.By positioning the U-shaped base profile and the L-shaped outer profile at a sufficient distance from the space intended to guide the lateral side of the screen during rolling and unrolling, damage to this crucial part of the lateral guide is avoided during assembly or disassembly, thus ensuring greater durability.

[0038] According to a particular embodiment, a cavity screen is described here in which the end of the short side of the L-shaped outer profile is fixed to the central piece of the U-shaped base profile by means of a snap closure, preferably a snap closure along the entire length of the side slide.

[0039] A snap fastener, also known as a clip fastener, is a type of fastener used to quickly and securely fasten two parts of an object together. It consists of two parts: a male part and a female part. The male part is generally fitted with a head with an integrated spring system, while the female part is designed to receive the male part. To close the snap fastener, the male part is inserted into the female part. The pressure exerted by the spring force of the male part securely locks the two parts in place. To open the snap closure, pressure is usually applied to a specific point, which releases the closure and allows the male part to be removed from the female part.

[0040] According to a particular embodiment, a cavity screen is described herein, wherein the end of the second tab of the U-shaped base profile and the corner of the L-shaped outer profile each have a facing edge which, together, secure the side profile into which the lateral side of the screen is slid. The edges extend inwards and form the edges of the opening through which the screen can pass. Furthermore, the edges ensure that the lateral profile remains in the space provided for this purpose.

[0041] According to a particular embodiment, a cavity screen is described herein in which the long side of the L-shaped outer profile and / or a portion of the central portion of the U-shaped base profile have a double wall. In order to combine flexibility and rigidity for the L-shaped outer profile and / or the U-shaped base profile, some walls of the profiles may be single-walled and / or double-walled, so as to provide the profiles with the necessary rigidity on the one hand and ensure sufficient flexibility on the other. Providing a double wall for at least a portion of the central section of the U-shaped base profile and / or the long side of the L-shaped outer profile significantly strengthens the lateral guide.Conversely, by equipping the short side of the L-shaped outer profile and / or one or both legs of the U-shaped base profile with a single wall, sufficient flexibility is given to the lateral guide so that the two profiles can be fixed to each other.

[0042] According to a particular embodiment, a cavity screen is described herein, in which the U-shaped base profile and the L-shaped outer profile of the side guides are made of metal, preferably aluminum. Aluminum has many advantages as a material, as it is both robust and lightweight, weather-resistant, and requires little maintenance. However, other materials are also suitable, and their advantages and disadvantages are assumed to be known to the professional.

[0043] According to a particular embodiment, here is the description of a cavity screen in which the lateral profile is made of plastic.

[0044] According to a particular embodiment, a cavity screen is described herein, in which the lateral guides further comprise one or more filling profiles, which are fixed to the outside of the tabs of the U-shaped base profile. The filling profiles described herein serve to fill the remaining spaces in the cavity so that the lateral guide fills the entire cavity and there are no more openings.

[0045] According to a particular embodiment, here is the description of a cavity screen in which the protective housing further includes one or more motors for automatically winding and unwinding the roll of the screen.

[0046] In another aspect, the present technology relates to a kit comprising the components of a cavity screen as described herein and an assembly tool for assembling and disassembling the outer L-shaped profile onto the U-shaped base profile. The assembly tool as described herein is a tool adapted for mounting the outer L-shaped profile onto the U-shaped base profile and / or for detaching the outer L-shaped profile from the U-shaped base profile. The assembly tool described herein is preferably a tool adapted to fit between the long side of the outer L-shaped profile and the tab of the U-shaped base profile so that they can be detached from each other.

[0047] In another aspect, the present technology relates to a method of mounting and / or dismounting a cavity screen as described herein, comprising the step of fixing the U-shaped base profile in a hollow wall and / or fixing and / or removing the outer L-shaped profile on the U-shaped base profile.

[0048] According to one particular embodiment, the method described herein comprises the following steps: • mount and fix the protective box and the U-shaped base profiles of the side guides in the hollow wall, possibly fixing infill profiles to the U-shaped base profiles; • Position the side profile in at least one of the U-shaped base profiles of the side guides; and • attach the outer L-shaped profiles to the U-shaped base profiles.
