[0002] Demonstration panel with a reinforcing layer

[0003] The invention relates to devices for visual information and advertising of various types and can be used in various fields: information, advertising, artistic design, education, in office and residential interiors, etc. as a notice board, information or exhibition stand, classroom corner, office or home board with reminders, etc.

[0004] A prior art technical solution, patent US7503136B1, published March 17, 2009, discloses an information board made of sandwich materials firmly and permanently bonded to one another using bonding layers. The board consists of an outer layer of open-weave fabric and a cork board. A disadvantage of this solution is that during use, the information board gradually deteriorates under the impact of sharpened pins driven into the cork layer. The board's holding capacity deteriorates, and the damage becomes visually visible through the fabric layer, significantly impairing the board's appearance. Furthermore, it is impossible to secure heavy objects to such a board. Furthermore, the fabric firmly attached to the cork board will not fully self-heal after the fastener is removed due to its rigid attachment to the cork board.

[0005] A technical solution is known under patent US9652795B2, published on 16.05.2017, which discloses a method for creating a self-healing notice board, including, among other things, the step of forming a self-healing notice board by gluing a canvas to a layer intended for inserting pins.

[0006] The disadvantage of this solution is that during the operation of the notice board, under the influence of the pins of the pointed pin fasteners inserted into the layer intended for inserting buttons, this layer is gradually destroyed - 02 / 12 / 2025

[0007] As the board wears, its holding power deteriorates, and the damage becomes visible through the canvas, significantly detracting from the board's appearance. Furthermore, it's impossible to secure heavy objects to such a board. Furthermore, if the canvas is glued to the tack layer, it won't fully self-heal due to its rigid attachment to the tack layer.

[0008] A technical solution known from patent US20060150454A1, published July 13, 2006, discloses a multilayer button panel, also adapted to hold magnets, comprising a pierceable composite sheet containing a magnetically attracted material. A drawback of this technical solution is that the properties of the pierceable composite sheet are not selected to ensure the panel is capable of holding heavy objects attached to it with a pointed pin fastener. Furthermore, the proposed solutions for attaching the title page to the pierceable composite sheet do not fully utilize its self-healing properties.

[0009] The closest to the proposed technical solution is the technical solution according to patent RU217583U1, published on 06.04.2023, which discloses a demonstration panel consisting of three layers: a carrier, an adhesive and a face layer, characterized in that the face layer is made of a textile fabric subjected to reversible elastic deformation by stretching when attached to the carrier layer, and the adhesive layer is made of a permanent adhesive.

[0010] The technical result of this solution is to preserve the appearance of the display panel after its repeated use.

[0011] The disadvantage of this solution is that during the operation of the panel, under the influence of pins of sharpened pin fasteners inserted into the supporting layer, the supporting layer of the panel is gradually destroyed, its surface is deformed - 02 / 12 / 2025

[0012] This becomes visually noticeable through the adhesive and face layers and significantly detracts from the panel's appearance. Furthermore, it is impossible to simultaneously place both light and heavy objects on the same panel using a pointed pin fastener, even with the usual effort, as this places conflicting demands on the properties of the supporting layer material.

[0013] All of the above technical solutions, as well as other known and applied technical solutions for various information panels, notice boards, classroom corners, etc., do not solve the problem of fastening both light and heavy objects to the same panel (board) with the usual force using pointed pin fasteners, since this places mutually exclusive demands on the properties of the materials used in these technical solutions, into which the pointed pin fastener is embedded.

[0014] The impossibility of easily and reliably fastening heavy objects to information panels is due to the fact that the pointed pin fastener, immersed in such panels, forms a lever structure of the 2nd kind, the support point (axis of rotation) of which is located in the depth of the panel, and the point of application of force (weight of the fixed object) is not deeper than the surface of the panel, which creates a tearing force along this surface, leading to its significant deformation, and as a consequence, to the loss of the fastener and / or irreversible damage to the appearance of the panel.

[0015] At the same time, the problem of fastening heavy objects to the panel, which will not lead to damage to the face and / or destruction of the base layer, cannot be solved either by increasing the rigidity or elasticity of the base layer of the panel, since this makes it difficult to insert a pointed pin fastener into this layer so much that it leads to the loss of the panel's performance properties, or, conversely, by increasing its elasticity in order to prevent destruction of the layer, since in this case the application of force (weight of the fixed object) from 02 / 12 / 2025

[0016] the sides of the pin fastener embedded in the panel leads to unacceptable deformation of the panel surface.

[0017] The objective of the present invention is to create a display panel with a reinforcing layer, on which, using pins, push pins, staples, small nails, and other rod fasteners with a pointed end, it is possible to securely fasten heavy information materials and objects, traces of which will no longer be visible after their dismantling.

[0018] The technical result consists in ensuring reliable fastening on information panels using various rod fasteners with a pointed end of heavy information materials and objects that otherwise cannot be easily fastened to such panels while maintaining the appearance of the panels.

[0019] A demo panel like this is needed:

[0020] - for the production of more universal, compared to known, information boards with new additional consumer properties and an extended service life, including those with high-resolution, damage-resistant images applied to their surfaces, namely:

[0021] - for the production of stands for holding periodic exhibitions, when it is necessary to reliably attach information (photographs, posters, text and graphic materials on various media, etc.) to such stands multiple times and in different orders, as well as, including heavy ones, subject materials (small exhibits, products, etc.);

[0022] - to create so-called classroom corners in kindergartens, schools, and other educational institutions with expanded possibilities for placing various objects and design elements on them; 02 / 12 / 2025

[0023] - for the production of stands for placing in public spaces changing information materials for various purposes (photographs, posters, text and graphic materials on various media, etc.) as well as heavy objects (small exhibits, products, etc.);

[0024] - for temporary placement of illustrative and informational materials, as well as heavy objects (small exhibits, product samples, etc.) during corporate events and meetings;

[0025] - for placing current information and reminders, as well as weighted objects (small exhibits, product samples, etc.) in offices and personal spaces.

[0026] The stated problem is solved, and the technical result is achieved, by the claimed demonstration panel with a reinforcing layer consisting of a base layer, a face layer, and a reinforcing layer located between them. Each layer is made of a synthetic or natural material. The base layer is 3-12 mm thick, the face layer is 0.1-3 mm thick, and the reinforcing layer is 0.5-3 mm thick. Each layer of the demonstration panel is constructed with thicknesses and from materials optimal for achieving the technical result.

[0027] The reinforcing layer may be reinforced with either fiber, fiber, or a material having a mesh structure. Ferromagnetic properties may also be imparted to the reinforcing layer. An adhesive layer made of a removable, permanently tacky, pressure-sensitive adhesive may be applied to the face side of the reinforcing layer. The face layer may be made of a textile fabric subjected to reversible elastic deformation by stretching during layer formation and / or a material with a surface structure capable of concealing a puncture after removal of the pointed fastener. An image may be applied to the face layer using digital printing on a flat surface, or the textile fabric forming the face layer may have a pre-printed image applied to it. 12.02.2025

[0028] the image itself, while the distortion during stretching during the layer formation process should be visually unnoticeable.

[0029] Implementation of a technical solution

[0030] A display panel with a reinforcing layer consists of three layers: a base layer, a face layer, and a reinforcing layer located between them. The base layer, 3-12 mm thick, is made of a material capable of inserting and retaining the main portion of a pointed dowel fastener with normal force. The reinforcing layer, 0.1-3 mm thick, is made of a more elastic and dense material relative to the base layer. The elasticity, viscosity, thickness, and other properties of the reinforcing layer are selected such that it can be pierced by a typically used pointed dowel fastener with normal force, under the appropriate load, while retaining the fastener from moving along the panel surface more strongly than the base layer, and after the fastener is removed, it returns to its original shape at the puncture site.

[0031] The proposed technical solution, thanks to the interaction of the reinforcing layer with the other layers of the panel, makes it possible to create reinforced self-healing display panels of various types, designed for fastening heavy objects to them using pointed pin fasteners without damaging the base layer and without visually distinguishable deformation of the face layer.

[0032] The essence of the invention is explained by drawings.

[0034] Fig. 2 shows a sectional view of the structure of the demonstration panel with reinforcement. 12.02.2025

[0035] layer, adhesive layer, additional rigid layer and a layer of binding material.

[0036] The reinforcing layer of the panel (1) is located on the main layer of the panel (2), made of a material into which the greater part of the pin of the pointed pin fastener can be immersed and held with the usual force for this, under its face layer (3) and is made of a more elastic and dense material in relation to the material of the main layer, wherein its elasticity, viscosity, thickness and other properties are selected in such a way that the reinforcing layer can be pierced by the pointed pin fastener (4) usually used for these purposes with the usual force for this, while holding such a fastener from displacement along the surface of the panel stronger than the main layer, and after removing the fastener, acquire the original shape at the puncture site.As a result of such a solution, the pointed pin fastener (4), immersed in the panel, forms a lever structure of the 1st kind, the support point (axis of rotation), which is located practically on the surface of the panel and, at the same time, in the body of the reinforcing layer (1), capable of reliably holding the part of the pointed pin fastener (4) located in its body from displacement along the surface of the panel, due to which the tearing force from the vertical load (weight of the fixed object), transmitted to the body of the base layer (2) is significantly reduced and does not lead to its damage, and the amount of displacement under the action of the same load of the facing layers (3) does not lead to its irreversible and / or visually distinguishable deformation.

[0037] The reinforcing layer of the panel (1) can be placed between the base layer (2) and the adhesive layer of the panel (5).

[0038] On the back side of the main layer (2) an additional rigid layer (6) can also be placed, which gives the entire panel additional rigidity and in which, in some cases, the pointed part of the pin fastener (4) can be fixed. 12.02.2025

[0039] The additional rigid layer (6) can be fastened to the main layer (2) by means of a layer of bonding material (7), which can be pierced with a pointed pin fastener usually used for this purpose with the force usual for this purpose.

[0040] The following materials can be used to produce a demonstration panel with a reinforcing layer:

[0045] In this case, the reinforcing layer can be formed directly on the surface of the base layer during its production, followed by its hardening through polymerization, drying, etc., and also, it can be pre-produced and rigidly fixed to the base layer by any known method.

[0046] The reinforcing layer can also be given ferromagnetic properties.
