Description

[0001] The utility model relates to devices for protection against insects and can be used for installation on windows, doors or other openings.

[0002] STATE OF THE ART

[0003] A prior art patent, RU 243058, "Mosquito Net," discloses a mosquito net device constructed as a rectangular structure consisting of several vertical profiles with a pleated mosquito net attached to them, moving along two horizontal guides located parallel to each other. One edge of the mosquito net is fixed to the vertical guide, and the other to the handle profile, thereby forming a movable sash. A wheel mechanism is located at the top and bottom of the sash, designed to move the sash along the horizontal guides. Two horizontal and two vertical guides form a rigid frame within which the sash is located. Magnets are located along the entire length of the handle profile and the vertical profile located opposite it, forming the side part of the frame of the structure, with opposite poles facing each other.The horizontal guides are designed as a U-shaped profile tapering toward the top, measuring 18 mm at the bottom and 17.6 mm at the top. The handle profile tapers toward the top, measuring 18.9 mm at the bottom and 17.8 mm at the top. A drawback of this existing solution is that the mosquito net is not securely fastened to the horizontal guide, which can cause play both when opening and closing the sash and when the mosquito net is open.

[0004] This product is the closest analogue of the declared solution (https: / / www.fips.ru).

[0005] Another analogue is the patent for utility model RU 114710 “Mosquito net”. From this source, a mosquito net device is known, consisting of a mesh insert placed in a frame base made of U-shaped profiles, with the possibility of rigidly attaching the device to a window, door or other opening, characterized in that the mesh insert is made removable in the form of an insert profile and a handle profile, at the ends of which shaped inserts are fixed with a mosquito net fixed between them, the function of which is to partially or completely cover a rectangular opening formed by the upper, lower and two side profiles, due to the pleated structure of the mesh itself from one side profile to another, and the U-shaped side profiles at the edges of the inner side of the section are made with triangular protrusions, the function of which is to fix / dismantle the insert profile and tightly connect with the side profile of the handle profile of the mesh insert,The U-shaped upper profile in the middle part has rectangular projections made with the possibility of tight connection and free movement along the upper profile of the upper figured insert of the handle profile and the mosquito net, and the lower U-shaped profile in the middle part has spherical projections, the function of which is tight connection and free movement along the lower profile of the lower figured insert of the handle profile and the mosquito net, as well as fastening in the spherical grooves of two sealing rubber bands made in the cross-section in the form of a spherical part proportionate to the spherical grooves and a triangular part, and with the possibility of protecting the internal cavities of the lower profile from moisture, dust and other contaminants, acute-angled parts with partial overlap to each other. The variant of the mosquito net device given in the dependent claim of the known analogue provides that the frame profiles can be fastened together by four corners with through holes,Designed to allow for rigid attachment of the device to a window, door, or other opening, using two rectangular inserts, proportionate in cross-section to the rectangular openings of the side, top, and bottom profiles, respectively, and along the outer fastening surface of which are U-shaped recesses for attaching Velcro straps designed to secure the device to the window, door, or other opening. A disadvantage of this known solution is the inability to control the tightness of the closed mesh against the side profile, as well as the lack of any system for securing the closed mesh when closing the window or door opening (https: / / www.fips.ru).

[0006] DISCLOSURE OF UTILITY MODEL

[0007] The technical objective of the claimed utility model is to increase the reliability of fastening the mosquito net fabric in horizontal guides.

[0008] The stated objective is achieved by implementing vertical and horizontal guides in the form of U-shaped profiles with a protrusion at the top, on the inner side of the profile. The protrusion is symmetrically located on both inner sides of the profile.

[0009] So, the mosquito net is made in the form of a rectangular structure, consisting of several vertical profiles with a pleated mosquito net attached to them, moving along two horizontal guides located parallel to each other, equipped with protrusions on their inner surface.

[0010] The mosquito net is secured to a vertical guide at one end and to a handle profile at the other, forming a sliding sash. A wheel mechanism is located at the top and bottom of the sash, allowing it to move along the horizontal guides.

[0011] Two horizontal and two vertical guides form a rigid frame, inside which the sash is located.

[0012] Along the handle profile and the vertical profile (2) located opposite it, which forms the side part of the frame of the structure, magnets are located along the entire length of the profiles, directed towards each other with opposite poles.

[0013] The horizontal guides are made in the form of a U-shaped profile with a protrusion in the upper part on the inside of the profile.

[0014] The presence of this protrusion, by reducing the space between the frame and the sash / frame and the mesh, increases the reliability of fixing the sash in the frame, minimizing the level of oscillation of the sash inside the frame, for example, under the influence of wind.

[0015] The technical result of the claimed utility model is to increase the reliability of fastening the mosquito net fabric in horizontal guides.

[0021] IMPLEMENTATION OF A UTILITY MODEL

[0022] The mosquito net is made in the form of a rectangular structure consisting of several vertical profiles (1) with a pleated mosquito net attached to them, moving along two horizontal guides (1) located parallel to each other, equipped with protrusions (2) on their inner surface.

[0023] Horizontal and vertical guides (1) are made in the form of a U-shaped profile with a protrusion (2) in the upper part on the inside of the profile.

[0024] The mosquito net is secured to the vertical guide (1) at one end and to the handle profile at the other, forming a sliding sash. A wheel mechanism is located at the top and bottom of the sash, which moves it along the horizontal guides.

[0025] Two horizontal (1) and two vertical (1) guides form a rigid frame, inside which the sash is located.

[0026] Along the handle profile and the vertical profile (1) located opposite it, which forms the side part of the frame of the structure, magnets are located along the entire length of the profiles, directed towards each other with opposite poles.

[0027] Example of implementation of the utility model.

[0028] A frame with a sliding sash is installed in the window opening. To prevent insects from entering the room, the user pulls the handle profile, sliding the mosquito net sash open. Once the handle profile is fully extended, it slides into the U-shaped frame profile, after which the extended sash is held open by magnets. The mosquito net frame has minimal play due to its tight fit to the guides.
