The multifunctional push pin (50) of the present invention comprises the main body (10) and the hook portion (20).

The push-pin main body 10 is composed of a head 11 and a pin 12.

As shown in Fig. 3, the head 11 has a flat shape such as a nail.

2 to 4, the fin 12 protrudes rearward from the rear center of the head 11. The fin portion 12 is formed into an elongated cylindrical rod inclined at an acute angle to the head portion 11 and has a sharp conical shape at its ends. The fin portion 12 is provided on the back surface of the nonwoven fabric 110 and the nonwoven fabric 110 to provide a cushioning force, The buffer board 130 is formed of a buffer plate 130 for supporting the buffer plate 130 and a plywood plate 140 for supporting the back surface of the buffer plate 130. The buffer plate 130 is supported by the bulletin board 100 through the nonwoven fabric 110 and the buffer plate 130. [

Since the fin 12 is inclined at an acute angle with respect to the head 11, when the post is posted on the bulletin board, the pin 12 can be supported on a nonwoven fabric or the like located on the front surface of the bulletin board covering the plywood.

At this time, if the push pin passes through the board 100 with the inclined fin portion 12 directed downward, the post pulls the pin portion 12 downward by its own weight, so that the inclined fin portion 12 is supported on the bulletin board. Therefore, even if the weight of the post is heavy, the pin 12 can be kept fixed to the bulletin board.

The vertical length of the fin 12 protruding from the head 11 to the rear of the head 11 is preferably smaller than the sum of thicknesses of the nonwoven fabric and the buffer plate provided on the front surface of the bulletin board.

The fin 12 may be formed by bending a portion of the fin 12 that is close to the head 11 so as to be inclined at an acute angle with the head 11.

At this time, the inclined angle of the fin 12 is preferably 10 to 40 degrees.

When the angle of inclination of the fin 12 is less than 10 degrees, it is difficult to fix the plate 12 through the bulletin board so that the fixing force is decreased. When the weight of the post is heavy, the problem of damaging the nonwoven fabric and the buffer plate have.

When the inclined angle of the fin 12 is more than 40 degrees, it is easy to be fixed to the bulletin board. However, if the weight of the post is heavy, the supporting force of the nonwoven fabric and the buffer plate provided on the front face of the plywood of the bulletin board is lowered, There is a problem in that it is difficult to publish a post because it is removed from the nonwoven fabric and the buffer plate.

The hooking part 20 is formed so that the head 11 of the push-pin main body 10 is accommodated and can hang the post.

The hanger portion 20 includes a receiving portion 21, a supporting portion 22, and a post mounting portion 23.

The receiving portion 21 is formed by injection so that the head portion 11 of the push-up pin 10 is received therein. When the pin portion 12 passes through the bulletin board 100, A flat first flat surface 21a is provided.

In this state, a post may be hanged and posted on the post post 23.

The angle between the support part 22 and the post mounting part 23 is about 60 to 85 degrees.

When the angle between the support part 22 and the post mounting part 23 is less than 60 degrees, the moment can not be transmitted to the lower end of the second flat surface 22a due to the load of the post when the post is mounted, 2 The bearing force of the post by the flat surface 22a becomes weak.

When the angle between the support part 22 and the post mounting part 23 is 85 degrees or more, a moment is transmitted to the lower end of the second flat surface 22a by the load of the post when the post is mounted, When the load of the post is excessively large, the moment of the post is increased by the load of the post, so that the pin portion 12 of the push pin 50 is separated from the nonwoven fabric 110 and the buffer plate 130).

Therefore, it is preferable that the angle between the support portion 22 and the post mounting portion 23 be maintained at an appropriate angle.

Further, the accommodating portion 21 is preferably spherical.

The pin portion 12 is formed by bending a portion close to the head portion 11 so as to be inclined at an acute angle with respect to the head portion 11. When the receiving portion 21 is formed into a spherical shape, So that the receiving portion 21 can be maintained in its shape without breakage when the fin 12 is bent.

The multifunctional press pin of the present invention having the above-described structure can position the post on the rear side of the hook 20 and can fix the post on the bulletin board by punching the post with the pin 12. In this case, apply to cases where the post is thin.

In addition, the post can be inserted and posted on the post mounting portion 23 of the hook portion 20 as shown in Fig. 3 without perforating the post by the pin portion 12. [ In this case, it can be applied to both thin and thick posts. In the case of a heavy or thick post, the post is placed on the post mounting portion 23 of the hook 20 to be posted. When the post is placed on the post mounting part 23, the post is fixed to the bulletin board by the inclined fin 12 and the lower end of the support part 22, so that a large amount of heavy post can be posted. In addition, since the pin portion 12 is formed to be inclined, it is possible to reduce safety incidents such as sticking by the pin portion 12.
