Description

[Technical Field]

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

[0002] The closest known technical solution is U.S. Patent No. 9,652,795 B2, published May 16, 2017, which discloses a bulletin board constructed with a support layer in the form of a rigid cork sheet or wood fiber backing. Due to the elastic properties of cork, holes made by thumb tacks close automatically when removed. However, with intensive use, the cork material deteriorates over time. Disadvantages of this bulletin board include the need for a special coating to seal the front layer, the fragility and limited durability of the cork layer, the inability to securely fasten relatively heavy informational materials, physical objects, and auxiliary elements, and the inability to use fasteners such as staples, small nails, or magnets.

[0003] Furthermore, U.S. Patent No. US1494583A, published on May 20, 1924, discloses a bulletin board consisting of a fire-resistant, non-deformable base, a cushion of elastic material firmly adhered to the base, and a border enclosing the cushion inside.

[0004] Disadvantages of this bulletin board include an insufficiently resilient front surface that does not self-heal around holes left after fasteners are removed. When relatively heavy informational, physical, and auxiliary materials are fastened, the top surface of the bulletin board sags or cracks at the penetrations, causing fasteners to fall out and permanently damaging the appearance of the panel.

[0005] Furthermore, reusable display boards are typically made by stretching a textile material over a rigid backing, with informational and display materials secured in place using metal, uniaxial sewing pins (tailors' or dressmakers' pins) with the pin shaft parallel to the surface of the board and oriented along the gravity vector. A drawback of such panels is that the puncture points in the textile layer are often separated from the surface of the display board by a distance significantly greater than the diameter of the pin shaft, allowing the sewing pins to rotate freely around the puncture points and easily fall off.

[0006] US Patent No. US9652795B2 US Patent No. US1494583A Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to produce a reusable display board (panel) with a self-repairing surface to which informational, physical and auxiliary materials can be securely fastened, if desired, using pins, thumb tacks, heavy-duty staples, tacks or other sharp fasteners, or magnets, without leaving any visible marks upon removal.

[0008] The technical effect is that the panel maintains its appearance even after multiple uses, while being able to be securely fastened using a variety of fasteners. Such panels are particularly useful for:

[0009] For the purpose of organizing regular low-budget exhibitions in educational institutions, community organizations, cultural institutions, etc., where informational materials (such as photographs, posters, textual and graphic materials on various media) or object materials (such as small exhibits) need to be repeatedly and securely fixed on vertical or inclined surfaces.

[0010] The purpose is to post (display) on stands in public spaces interchangeable information materials (photos, posters, text and graphic material on various media, etc.) for various purposes.

[0011] The purpose is to temporarily place informational and explanatory materials during corporate events and meetings.

[0012] The purpose is to display updates and reminders in your office or personal space. [Means for solving the problem]

[0013] The above-mentioned objectives are achieved and the above-mentioned technical effects are realized by providing a display board with a self-healing surface consisting of at least three layers: a backing layer, an adhesive layer, and a front layer, wherein the front layer is made of a fibrous material that undergoes reversible elastic deformation when stretched and attached to the backing layer, and the adhesive layer is made of a permanently tacky pressure-sensitive adhesive.

[0014] The principles of the present invention will now be explained with reference to the drawings. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. 2 is a diagram showing the structural configuration of a display board (panel). [Figure 2] FIG. 1 shows a display board with fixing elements and attached informational and object materials. DETAILED DESCRIPTION OF THE INVENTION

[0016] The backing layer 1, manufactured to the desired dimensions, is formed from one or more layers of sheet material, which may be secured to a frame for added structural rigidity.

[0017] Adhesive layer 2 is made by applying a suitable layer of permanently tacky pressure-sensitive adhesive to each surface of backing layer 1 facing front layer 3. A layer is considered suitable if it is 0.5 mm (millimeter) thick or greater.

[0018] An additional layer 4 with ferromagnetic properties may be arranged between the backing layer 1 and the adhesive layer 2 or may be integrated within the adhesive layer 2 itself.

[0019] The adhesive layer 2 may be applied in two stages, with a thin mesh having ferromagnetic properties embedded between the layers.

[0020] The fibrous material forming the front layer 3 is stretched over the adhesive layer 2 and secured by any suitable means to either the back side or the edges of the backing layer 1. The fibrous material should have a density of at least 340 grams per linear meter to ensure reliable retention of both informational and physical material.

[0021] Additionally, the textile material used should have a low pile so that adhesive tape and other self-adhesive materials (such as stickers) can adhere well to its surface.

[0022] Any desired image or graphic may be applied to the front layer 3, which is made of a textile material, using suitable techniques.

[0023] The finished panels can be mounted vertically, at an angle, or horizontally using any applicable known method, or conventional methods typical in display boards and information stands may be used.

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

[0025] The fastening elements are metal single-shaft sewing pins 7 (tailor's or dressmaker's pins), thumb tacks 8, staples 9, small nails or other pointed shaft fasteners 10, magnets 11 (if the display board includes a ferromagnetic layer 4), single-sided adhesive tape 12, double-sided adhesive tape 13.

[0026] An example of an embodiment of a display board is as follows: Backing layer 1 is FK sandpaper plywood, 10 mm (millimeters) thick, 1525 x 1525 mm in size, grade 2 / 2, GOST 3916.1-2018, manufactured by Novy Resurs, LLC.

[0027] Adhesive layer 2 is 0.5 mm thick and is formed using Scotch PhotoMount spray adhesive manufactured by 3M Co. (Poland). Ferromagnetic intermediate layer (ferromagnetic layer 4) is formed from a 0.4 × 0.4 cm (centimeter) low-carbon steel woven wire mesh (black) with a diameter of 0.25 mm (millimeter) in accordance with GOST 3826-82, provided by Novometall Trade, LLC.

[0028] Front layer 3 is gabardine LHG100-04 / 150, 230 g / m 2 (grams per square meter), is smoothly dyed, solid color, double-sided, made of 100% polyester, has a density of 340g per linear meter, and is made in China.

[0029] The self-righting display board described above is used as follows: the user attaches the necessary information and display materials to the board using single-shaft metal sewing pins 7 (tailor's or dressmaker's pins). The reliability of this fastening method is ensured by the pin shaft being located inside the adhesive layer 2.

[0030] The shaft of the pin, located inside adhesive layer 2, is aligned parallel to the surface of the display board, and its direction from the puncture point in front layer 3 coincides with the vector of gravity. As a result, the pin head is pressed against the surface of the display board, with the local elasticity of front layer 3 and adhesive layer 2 holding the material in place and the viscosity of adhesive layer 2 ensuring that the shaft remains in place without rotating around the puncture point.

[0031] To remove informational or display materials, simply remove the pins in the opposite direction to gravity. If the materials are attached to panels where the backing layer 1 is made of plywood, wood, or other dense fibrous material that can securely hold sharp fasteners with minimal effort, additional fastening options may include thumb tacks, staples, small nails, and other fasteners with pointed shafts. To remove these materials, the fasteners can be carefully removed using conventional methods.

[0032] For panels in which a ferromagnetic layer is incorporated between the backing layer 1 and the adhesive layer 2 or as part of the adhesive layer 2, magnets may also be used for attachment.

[0033] If the backing layer 1 is made from a ferromagnetic composite polymer sheet, magnets or pins can be used to attach materials as well.

[0034] If the front layer 3 is made of a high density, low pile fibrous material, single or double sided adhesive tape (such as Scotch® tape) or self-adhesive materials (such as stickers) can also be used.

[0035] After removal of the material, holes in the front layer 3 will gradually self-heal due to the local elasticity of the front layer 3 and adhesive layer 2, or can be quickly repaired manually by gentle smoothing.

[0036] A display board with such a self-repairing front layer 3 can be reused multiple times to display information and exhibit content without affecting its appearance.

[0037] The adhesive layer 2 is protected from dust and external influences by the front layer 3 and therefore retains its properties throughout the operational life of the display board.

[0038] For decorative or informational purposes, the fibrous layer of the front layer 3 may be formed from textile materials in a variety of colors with patterns or printed images.

[0039] As described above, the present invention provides secure fastening with a variety of fasteners while maintaining the appearance of the display board even after repeated use.
