Abstract

(57) [Summary] [Purpose] To provide a thumbtack for stably fixing (sticking) paper to a plate wall or the like. [Structure] A main body 1 made of an arbitrary material, a sharp needle 2 and an elastic member 3 fixed to the main body 1. [Effect] Since the paper is pressed and fixed to the plate wall or the like by the bottom surface of the elastic member 3, it is possible to prevent the paper from being slackened or torn due to the displacement of the paper to enlarge the hole by the needle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thumbtack for fixing (sticking) paper to a plate wall or the like.

[0002]

[Prior art]

 Conventional pushpins should be fixed when fixing paper (especially thin paper) to the board wall, etc., because the length of the needle is long and it is difficult to pierce the needle to the base of a general hard board wall. The papers were fixed by small holes with needles, that is, the dots. For this reason, when the paper was corroded, exposed to wind (including air conditioners), or fixed for a long period of time, the paper slipped and the small holes gradually became larger and were fixed. There was a drawback in that it was difficult to use, as the paper could slacken, and eventually it could tear.

[0003]

[Problems to be solved by the device]

 In order to eliminate the above-mentioned drawbacks, the present invention, when fixing paper to a plate wall or the like, press the paper with the surface and fix it without touching the needle to the base of the paper, touch the paper, or wind it. The aim is to provide a method that can be stably fixed for a long period of time even in an environment where it will be hit by light.

[0004]

[Means for Solving the Problems]

 This can be achieved by using a thumbtack composed of a main body 1 made of an arbitrary material, a sharp needle 2 and an elastic member 3 fixed to the main body 1.

[0005]

[Action]

 Since the present invention employs the above-mentioned means, even if the needle 2 is not forcefully pierced into the plate wall or the like, the paper is prevented from moving because the elastic member presses and fixes the paper with the surface. Therefore, it is possible to prevent the slack and tear of the paper.

【Example】

 FIG. 1 is a front view of one embodiment, and FIG. 2 is a bottom view thereof. A sharp needle 2 whose tail is embedded in the body 1 at the center of the circular bottom surface of the body 1 made of any material (synthetic resin, metal, etc.) Is fixed. The elastic member 3 is pushed out by the needle 2 and is concentrically fixed to the needle 2 on the bottom surface of the main body by an adhesive or the like. The head of the needle 2 slightly projects from the surface of the elastic member 3. The elastic member 3 is a soft elastic material such as sponge or rubber, and the bottom surface portion is the softest, and the hardness is increased as it approaches the main body 1. The above-mentioned homogeneous elastic material having an average softness may be used as it is. Alternatively, as shown in FIG. 3, a soft elastic material 5 is provided on the bottom portion and a slightly hard elastic material is provided on the main body 1 side portion. A multi-layer structure such as 4 may be used. On the contrary, including the case of FIG. 1, the soft side may be the main body 1 side, the slightly hard side may be the bottom side, and the bottom side may be a thin hard plate. However, in any case, the bottom surface should be made of a material and surface condition (such as making fine irregularities) so that the friction resistance with the paper is large.

Using the thumbtack of FIG. 1 configured as described above, if a piece of paper that is easy to tear is fixed (attached) to a plate wall or the like, when the tip of the needle 2 pierces the plate wall slightly, the elastic member 3 The elastic member 3 is compressed as the bottom surface touches the paper and the needle 2 is further inserted, and the paper is pressed against the plate wall, and the paper can be pressed and fixed by the bottom surface of the elastic member 3. Therefore, as in the case of the conventional thumbtack, the papers are displaced, the holes are enlarged, and the fixed papers are not loosened or torn.

FIG. 4 is a front view of another embodiment, and FIG. 5 is a bottom view thereof. The main body 1A of this embodiment is exactly the same as that of the above-mentioned embodiment except that the main body 1A has a flat plate shape, and therefore its operation is also the same. The diameter of the elastic member 3 is made smaller than that of the main body 1A so that the nail or the like can be easily caught by the main body 1A when the thumbtack is pulled out from the plate wall, and the pulling out is facilitated. In this embodiment, since the height of the thumbtack is low, there is an advantage that it does not interfere with other things and that other things do not touch and fall out.

Although the bottom surface is circular in the above embodiments, it is needless to say that the bottom surface may be any shape such as an ellipse or a quadrangle. Further, the shape of the main body 1 in FIG. 1 is as shown in the same drawing because of the ease of piercing and the ease of pulling out, but the shape is not limited to these shapes including the case of FIG.

[0010]

[Effect of device]

 Since the papers are pressed against the board wall and fixed, it is possible to prevent the papers from sagging or tearing.
