Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a laminate for a bulletin board and a bulletin board. More specifically, a laminate for a bulletin board mainly composed of a non-woven fabric layer and a sponge layer containing a magnetic material, in which a magnet and a thumbtack can be used, and the laminate for a bulletin board were adhered to a self-supporting substrate. About bulletin boards.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, various types of bulletin boards to which a memo sheet or the like can be attached using both a magnet and a thumbtack have been proposed. The most typical one is obtained by laminating a support such as a metal or a plate, a soft layer in which a magnetic substance is dispersed, an adhesive layer, and a surface layer.

[0003] This conventional type of bulletin board achieves its intended purpose of attaching memo paper or the like with both a magnet and a thumbtack, but has a four-layer structure, is relatively heavy, and is purchased by a purchaser. It is not a structure that can be cut into any desired shape and used.

[0004] The use form of the bulletin board is not necessarily uniform, and in terms of installation space, there are installation places where there is relatively room, such as a station building, an educational facility, a company, a store, and a hospital, while a home, a study, a kitchen, a children's room, and the like. Some are relatively narrow. In terms of users, even a relatively heavy bulletin board can be easily moved from an adult boy to a schoolchild, infant, elderly person, unhealthy person, etc. who cannot move it easily. Is wide.

[0005]

[Problems to be solved by the invention]

 Therefore, the problem to be solved by the present invention is that a conventional bulletin board on which a memo paper or the like can be attached with both a magnet and a thumbtack is relatively large and heavy, so that school children, toddlers, elderly people, and unhealthy people can use it. It cannot be used easily and easily by a wide range of users.

[0006] Another problem to be solved by the present invention is that a conventional bulletin board on which a memo sheet or the like can be attached with both a magnet and a thumbtack is relatively large and heavy, and moreover, the purchaser wishes after purchasing. Since it is not a structure that can be cut into arbitrary shapes and used, it cannot be used in relatively narrow places such as homes, study rooms, kitchens, and children's rooms.

[0007]

[Means for Solving the Problems]

 The present invention, which is a means for solving the above problems, is a bulletin board laminate mainly composed of a nonwoven fabric layer and a sponge layer containing a magnetic material, and capable of using a magnet and a thumbtack.

Further, the present invention, which is a means for solving the above-mentioned problem, has a laminate for a bulletin board in which a nonwoven fabric layer and a sponge layer containing a magnetic material are laminated and integrated with a self-supporting substrate. , A bulletin board that can use a magnet and a thumbtack.

The bulletin board laminate of the present invention is highly flexible and can be cut easily, so that a user or the like cuts it into an arbitrary shape and adheres to the surface of various articles by a predetermined means. As such, it can be used as a bulletin board.

Since the laminate for bulletin boards of the present invention is rich in flexibility and can be easily cut, a user or the like cuts it into an arbitrary shape and adheres to a self-supporting substrate by a predetermined means. Thus, it can be used as a partition type or wall-mounted type bulletin board. Examples of the self-supporting substrate include a wood-based material, a plastic, and a metal which have been conventionally used as a board for a bulletin board.

[0011] The nonwoven fabric constituting the laminate for bulletin boards of the present invention is superior in physical properties such as tissue stability, elongation elastic modulus, compression elastic modulus, and shrinkage ratio to woven fabric. Even if the steel penetrates, it is restored as soon as it is pulled out and the pinholes are closed, so it is effective as a support layer. Raw materials for the nonwoven fabric include cotton, rayon, acetate, nylon, polyester and the like in the case of short fibers.

The sponge layer constituting the laminate for a bulletin board of the present invention is a sponge layer of a thermoplastic synthetic resin such as rubber, EVA or polyvinyl chloride, or a mixture of rubber and a thermoplastic synthetic resin. The expansion ratio ranges from 2 to 4 times. When the expansion ratio is less than 2 times, thumb tacks, pins and the like are penetrated and the resilience after pulling out is poor. Conversely, when the expansion ratio is 4 times or more, the strength is reduced, which is not preferable.

[0013] By the way, cork is lightweight, and has high flexibility and elasticity, so that a thumbtack, a pin or the like penetrates and a pinhole is easily restored after being pulled out. It is preferable to make them adhere.

The magnetic substance uniformly dispersed in the sponge layer constituting the laminate for a bulletin board of the present invention is strongly magnetized since iron, cobalt, nickel and their compounds do not particularly follow the linear equation of the magnetic field. It is preferable because it is a so-called ferromagnetic material. Among them, iron is particularly preferable because iron has a good price and processability when dispersed in a thermoplastic synthetic resin such as rubber, EVA or polyvinyl chloride, and a mixture of a rubber and a thermoplastic synthetic resin. The form of use in the case of iron is powder or fiber, so-called steel fiber.

Hereinafter, the present invention will be specifically described with reference to examples.

Embodiment 1 FIG. 1 is a sectional view of an embodiment of a laminate for a bulletin board according to the present invention. Reference numeral 1 denotes a nonwoven fabric layer having a thickness of 0.4 mm manufactured by melt-spinning a polyester short fiber as a raw material by a spun bond method. Reference numeral 2 denotes a sponge layer made of polyvinyl chloride containing iron powder as a magnetic substance and having a foaming ratio of 2 times and a thickness of 0.8 mm. The first nonwoven fabric layer and the second sponge layer were adhered with an adhesive, laminated and integrated.

[0016]

Second Embodiment FIG. 2 shows a bulletin board laminate having the same structure as that of the first embodiment except that a 1.0 mm-thick cork is adhered to the surface of the laminate for a bulletin board manufactured in the first embodiment. .

[0017]

Third Embodiment FIG. 3 shows a bulletin board manufactured by bonding the laminate for a bulletin board of the first embodiment to a wooden board having a thickness of 1.0 mm.

[0018]

[Effect of the invention]

 As described above, the laminate for a bulletin board of the present invention is rich in flexibility and can be easily cut, so that a user or the like cuts into an arbitrary shape and adheres to the surface of various articles by a predetermined means. By itself, it can be used as a bulletin board. In addition, the laminate for bulletin boards of the present invention is rich in flexibility and can be cut easily, so that a user or the like cuts it into an arbitrary shape and adheres to a self-supporting substrate by a predetermined means. , Can be used as a partition type or wall mounted type bulletin board.
