Description

Technical Field

[0001] The proposed invention relates to a device for various types of visual presentation and advertising and can be used in information display, advertising, decoration, education and similar fields. Background Art

[0002] The closest known technical solution is U.S. Patent No. US9652795B2, published on May 16, 2017. This patent discloses a bulletin board composed of a support layer in the form of a hard cork board or a wood fiber backing. Due to the elasticity of the cork, the holes punched by the thumbtacks automatically close after removal. However, with frequent use, the cork material degrades over time. Disadvantages of this type of bulletin board include the need for special coatings to seal the surface layer; the brittleness and limited durability of the cork layer; the inability to reliably secure relatively heavy informational materials, physical materials, and auxiliary components; and the inability to use fasteners such as heavy staples, small nails, and / or magnets.

[0003] Furthermore, US Pat. No. 1,494,583A issued on May 20, 1924 discloses a bulletin board including a fireproof and non-deformable base, a pad of elastic material firmly bonded to the base, and a frame wrapped inwardly around the pad.

[0004] Disadvantages of this type of panel include a lack of surface elasticity and an inability to self-heal around penetrations left after fastener removal. When securing relatively heavy informational or physical materials and auxiliary components, the top surface of the panel may sag or crack at the penetration point, causing the fasteners to fall out and permanently damaging the panel's appearance.

[0005] Furthermore, reusable display panels are typically made by stretching a textile material onto a rigid backing board and using a metal uniaxial sewing needle (tailor's or dressmaker's needle) to secure information and display materials, with the needle shaft parallel to the board surface and the direction from the perforation point aligned with the gravity vector. A disadvantage of such panels is that the distance between the perforation point in the textile layer and the board surface is often significantly greater than the diameter of the needle shaft, allowing the needle shaft to rotate freely around the perforation point and easily fall off. Summary of the Invention

[0006] The present invention is directed to a reusable display board having a self-healing surface to which informational materials, physical materials, and auxiliary elements can be securely fastened when necessary using pins, thumbtacks, heavy-duty staples, tacks, or other pointed fasteners that leave no visible trace after removal, as well as magnets.

[0007] The result: reliable fastening using a wide range of fasteners while maintaining the panel's appearance even after repeated use.

[0008] These panels are particularly suitable for:

[0009] Regular, low-budget exhibitions held by educational institutions, community organizations, cultural institutions, etc., where informational materials (e.g., photographs, posters, text and graphics in various media) or physical materials (e.g., small exhibits) need to be repeatedly and securely attached to vertical or inclined surfaces;

[0010] For displaying interchangeable information materials for various purposes (e.g. photographs, posters, text and graphic materials in various media) on exhibition stands in public places;

[0011] For temporary placement of information and instructional materials during company events and meetings;

[0012] Used to display the latest information and reminders in the office and personal space.

[0013] This objective and technical achievement is achieved by providing a display board with a self-healing surface, the display board comprising at least three layers: a backing layer, an adhesive layer, and a surface layer. The surface layer is formed of a textile fabric that undergoes reversible elastic deformation due to stretching when the surface layer is fixed to the backing layer; and the adhesive layer is composed of a permanently tacky pressure-sensitive adhesive. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The essence of the present invention is explained with reference to the accompanying drawings.

[0015] Figure 1 The structural configuration of the display board is illustrated.

[0016] Figure 2 A display board is shown with fastening elements and attached informational and physical materials. DETAILED DESCRIPTION

[0017] The backing layer 1 is formed from one or more layers of sheet material, manufactured to the required dimensions. To increase structural rigidity, these layers may be fixed to a frame.

[0018] The adhesive layer 2 is formed by applying a suitable amount of a layer of a permanently tacky pressure-sensitive adhesive to each surface of the backing layer 1 facing the surface layer 3. It is also acceptable if the thickness of the layer exceeds 0.5 mm.

[0019] The additional layer 4 having ferromagnetism may be placed between the backing layer 1 and the adhesive layer 2 , or the additional layer 4 having ferromagnetism may be integrated into the adhesive layer 2 itself.

[0020] The adhesive layer 2 can be applied in two stages with a thin ferromagnetic mesh embedded between the layers.

[0021] The textile fabric forming the surface layer 3 is stretched over the adhesive layer 2 and secured to the reverse side or edge of the backing layer 1 by any suitable means. The density of the textile fabric must be at least 340 grams per linear meter to ensure reliable retention of informational and physical materials. In addition, the textile fabric used must be low-linting so that adhesive tape or other self-adhesive materials (such as stickers) can adhere securely to its surface.

[0022] Any desired images or graphics may also be applied to the textile fabric 3 using suitable techniques.

[0023] The completed panels may be mounted using any suitable known method in a vertical, inclined or horizontal orientation, or in any conventional manner commonly used for display boards and information racks.

[0024] The informational material 5 and / or the physical material 6 can be secured to the panel using any suitable known technique. The materials 5 and 6 can be secured to the display board using the following fastening elements:

[0025] - a metal single-shaft sewing needle 7 (a tailor's needle or a dressmaker's needle);

[0026] - thumbtack 8;

[0027] - Staples 9;

[0028] - Small nails or other pointed fasteners 10;

[0029] - a magnet 11 (provided that the display board comprises a ferromagnetic layer 4);

[0030] - Single-sided tape 12;

[0031] -Double-sided tape 13.

[0032] An example embodiment of a display board is as follows: the backing layer is made of 10 mm thick FK sanded plywood, measuring 1525 x 1525 mm, grade 2 / 2, in accordance with GOST 3916.1-2018, and manufactured by Novy Resurs, LLC. The adhesive layer is 0.5 mm thick and applied using Scotch Photo Mount spray adhesive manufactured by 3M (Poland). The ferromagnetic intermediate layer is made of woven mild steel wire mesh (black), measuring 0.4 x 0.4 cm, with a wire diameter of 0.25 mm, in accordance with GOST 3826-82, and supplied by Novometall Trade, LLC. The surface layer is made of 230 g / m² gabardine LH G100-04 / 150, gloss-dyed, solid color, double-sided, 100% polyester, with a density of 340 g / m, and produced in China.

[0033] The method of using the self-recovery display board is as follows.

[0034] Users primarily use single-shaft metal sewing needles (tailor's or dressmaker's needles) to secure the required informational and display materials to the board. The reliability of this fastening method lies in positioning the needle shaft within the adhesive layer so that it is parallel to the board surface, with the direction from the puncture point in the surface layer aligning with the gravity vector. Consequently, the needle tip is pressed against the board surface, securing the material in place due to the localized elasticity of the surface and adhesive layers. The adhesive layer's viscosity reliably holds the shaft in place, preventing it from rotating about the puncture point.

[0035] To remove information or exhibit material, simply pull out the needle in the opposite direction of gravity.

[0036] For mounting materials on panels with a backing layer made of plywood, wood, or other high-density fiber materials that can easily and securely hold pointed fasteners, additional fastening options may include thumbtacks, staples, small nails, and other pointed fasteners. To remove these materials, carefully extract the fasteners in the usual manner.

[0037] For panels that include a ferromagnetic layer between the backing layer and the adhesive layer, or a ferromagnetic layer as part of the adhesive layer, magnets can also be used for attachment.

[0038] If the backing layer is made of a ferromagnetic composite polymer sheet, magnets or pins can also be used to hold the material in place.

[0039] If the surface layer is made of a high-density, low-lint textile fabric, single-sided or double-sided adhesive tape (e.g. tape) or self-adhesive materials (such as stickers).

[0040] After removing the material, the perforations in the surface layer will gradually self-heal due to the local elasticity of the surface layer and the adhesive layer, or the perforations in the surface layer can be immediately eliminated manually by gently smoothing.

[0041] Panels with this self-healing surface layer can be reused multiple times for displaying information and exhibits without affecting their appearance.

[0042] Since the surface layer blocks out dust and external influences, the adhesive layer maintains its properties throughout the service life of the board.

[0043] The surface fabric may be made of textile material in various colors and may carry patterns or printed images for decorative or informational purposes.

[0044] Therefore, the present invention can achieve reliable fastening by various fasteners while maintaining the appearance of the display board even after repeated use.
