Abstract

PURPOSE:To enable the repetitive attachment and detachment of an object to be noticed without thumbtacks, etc., by forming adhesive fixing materials having foamed acrylic layers on the surfaces of a base material formed of molded flat plates consisting of wood, metals, resins, etc., by adhesive layers. CONSTITUTION:The foamed resin is used as the base material 5. The molded flat plates 4 consisting of the wood systems, metallic systems, resin systems, etc., are formed by the adhesive layers 3 on both surfaces of this base material and the sheet- like adhesive fixing materials 1 provided with the foamed acrylic layers are formed by the adhesive layers 3 on the surfaces thereof. Protective films 2 to be removed at the time of use are freely strippably attached to the adhesive fixing materials 1. A meringue-like foaming emulsion contg. a liquid agent of a general soft acrylic system is used and is applied on a blank material, such as cloth, paper or rubber, and is cured to form the acrylic layers. As a result, the foamed acrylic layers are soft and have elasticity. The surfaces thereof are made into numerous extremely small suction cup shapes and have a weak tacky adhesive effect and, therefore, these layers are stuck on a layer surface in a stable state at the time of attaching the notice board to the layer surface The surface adhesive fixing force is functioned by the weak tacky adhesiveness of the base material itself and the fitting of the surface to be adhered by the soft foam.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a magnet, a thumbtack, a tape,
Without intervening tools to support posted items such as staples
The ability to attach and detach the surface of the bulletin board can support the posted object, and can be easily attached and detached regardless of the size of the posted object. The present invention also relates to an uneven or flat bulletin board having an unprecedented visual appeal due to the flexibility of the adhesive material.

[0002]

2. Description of the Related Art Conventional bulletin boards are usually made of wood, vinyl, steel plates, or thin rubber magnets and are usually coated with paint or the like. It does not have any function.

In order to support a material such as an advertisement on such a bulletin board, it must be carried out by interposing a thumbtack, a tape, a stapler, a magnet, a steel plate piece or the like, which is troublesome, and particularly a thumbtack or a stapler. However, there is a drawback that the surface of the bulletin board is scratched and cannot be used for a long period of time.

As a type of bulletin board, there is a spherical sticky substance-attached product on the surface of the bulletin board, but since the sticky substance-added substances are not in a continuous form, the cohesive force between the sticky substance-added substances is weak and the sticky substance-provided substance surface is However, there is a problem in that the sticky substance-attached material adheres to the posted object and drops off from the bulletin board surface when the posted object is repeatedly attached and detached, and there is a problem in reusability.

There is also an adhesive bulletin board in which an adhesive is applied to a flat base material such as wood, paper or vinyl chloride sheet having a smooth surface. In this bulletin board, after an object such as paper is pasted,
When attempting to remove the paper, the adhesive surface between the paper and the adhesive bulletin board was too large, and there was a drawback that the adhered paper or the like would break.

There are bulletin boards having metal fittings for holding the material to be posted, but if the metal fittings are adapted to any curved surface, the shape is limited, and the number of parts increases and the manufacturing cost increases. And the number of processes increases in the production process. Problems such as metal fitting failure may occur during long-term use.

Although the known bulletin board is used only on one side,
When the surface of the bulletin board was damaged, a new bulletin board had to be purchased. It took time to deliver on the bulletin board.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks of the known bulletin boards. It supports a material to be posted without interposing a sandwich, and not only a flat surface but also an uneven surface. It is an object of the present invention to provide a bulletin board that can be easily improved against damage and the like so that the posted matter can be easily attached / detached even in the bulletin board.

[0009]

[Means for solving the problem] smooth wood-based / metal-based
Use a bulletin board that has a thin plate-shaped sticking / removing agent made of a flexible material such as a non-woven fabric, cloth, or rubber coated with foamed acrylic on a resin-molded flat plate or curved plate as a base material to display the whole or part of the posted material. The purpose is achieved by attaching.

[0010]

The surface of the adhesive bulletin board is a flexible acrylic layer coated on one side of a flexible base material, which itself has flexibility and elasticity. Since the surface of the foamed acrylic itself has an infinite number of extremely small suction cups and exerts a very weak adhesive action, when the object is lightly pressed onto the surface, the surface is well adhered to the adhered surface. Even if it is a familiar rough surface, it can be securely attached and detached, and a bulletin board having a curved surface becomes possible.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view showing an embodiment of an adhesive bulletin board according to the present invention. Using a foamed resin as a base material (5) and an adhesive layer (3) such as chemical glue, wood-based, metal-based, resin-based molded flat plates (4) are formed on both sides, and a foamed acrylic layer is formed on the surface. A thin plate-shaped adhesive agent (1) applied to a thickness of about 1 mm is formed on the surface of a molded flat plate (4) by an adhesive layer (3), and the adhesive material (1) has a protective film ( 2) is attached detachably. It is formed of a frame frame (6) such as aluminum, and a fixing screw (8) attached to a metal fitting (7) fixed to a wall surface is formed in the frame frame.

For the above-mentioned acrylic layer, a general soft acrylic liquid agent is physically agitated to form a meringue-like foamed emulsion, which is applied onto a material such as cloth, paper or rubber. It has been cured. By doing so, the foamed acrylic layer is softened and has elasticity, and the surface thereof has an infinitesimal number of suction cup-shaped moldings, which exerts a very weak adhesive action, so that when the protective film is peeled off and then attached to the layer surface, it is not covered. It is attached in a stable state to the adhesive surface.

The surface adhesion force of the foamed acrylic layer of the adhesive bulletin board A functions due to the weak adhesiveness of the substrate itself and the conformability of the soft foam to the adhered surface, so that the adhered surface is rough. Even if there is such a bulletin board, the bulletin board can be tightly stuck and sandwiched, and at the same time, re-sticking after peeling can be performed easily and surely, so that the work for changing the posted object can be performed in a timely manner. When the adhesive strength of the surface foamed acrylic layer of the adhesive bulletin board A decreases, the adhesive strength can be recovered by washing the surface of the layer with water to remove the adhered dust. Also, by embossing, the adhesive strength can be easily changed. Since the adhesive strength of the foamed acrylic layer is not destroyed even at an ambient temperature of its physical shape and structure of about 100 ° C., the material can be supported even on an outdoor bulletin board especially in summer and when the temperature is high.

FIG. 2 is a perspective view of a flat sticking bulletin board (claim 1) according to the present invention. In the case of a flat surface, both sides of the bulletin board can be used by forming adhesive materials on both sides.
The front and back can be easily replaced with the fixing metal fittings (7) and the fixing screws (8).

FIG. 3 is a perspective view of a curved surface sticking bulletin board (claim 2) according to the present invention. In the case of a curved bulletin board, there are two types of uneven surfaces. The concave bulletin board, which was difficult to attach in the past, is described below. A concave shape is conceivable as a bulletin board that can be viewed from a certain direction (arrow a). Conventionally, the shape is difficult to attach, but the flexibility of the adhesive material made of foamed acrylic makes it easy to attach and remove.

[0016]

[Effect] As described above, the adhesive bulletin board according to the present invention is
The physical adhesive force based on the adhesive action on the surface of the foamed acrylic layer ensures a proper fit and exerts an appropriate adhesive force on the adherend surface, while enabling re-adhesion after peeling. Therefore, it is possible to stick and hold in a stable state by simply pressing the posted object on the sticky bulletin board surface,
By reducing the number of parts, it becomes possible to mass-produce in a short period at low cost.

In the case of a flat adhesive board, both surfaces can be used by having adhesive materials on both sides, and troubles such as breakage can be promptly avoided. The bulletin board can be easily attached / detached on the curved board as well as the flat-adhesive bulletin board, and the bulletin board can be easily fitted to the curved surface for easy visual recognition.

As a material particularly suitable for the sticky bulletin board of the present application, there are resin-made medical examination tickets, membership cards and the like. Generally, it is difficult to search if there are a lot of resin-made medical examination tickets that are left behind at hospitals, but if you attach and detach them on the sticky bulletin board of the present application, it will be difficult to post them with conventional pushpins or staples. It is possible to prevent damage to the medical examination ticket and post it, and it is possible to search easily.
