[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thumbtack puncher, and more particularly to a thumbtack puncher which ensures that a thumbtack with a head removed can be removed.

[0002]

2. Description of the Related Art When posters, photographs, pictures, and the like are displayed in schools and other places where a large number of people enter and leave, it is common to attach them to display boards using thumbtack. Need to remove the thumbtack. However, when the thumbtack is old, when the thumbtack is pulled out, the connection between the head and the foot of the thumbtack pushed into the display board may break, leaving only the head, leaving the foot on the display board. Was.

[0003] The feet of the thumbtack may be caught and hurt by the palm or fingertips of the person who will be performing the display work next time. Particularly in elementary schools, children tend to be injured by the feet of the thumbtack that remains, causing a problem. Therefore, it was necessary to pinch the thumb of the thumbtack with pliers and remove it from the display board.

[0004]

[Problem to be Solved by the Invention] However, the work of pulling out the thumbtack with pliers is very complicated, and especially troublesome work for elementary school teachers is troublesome. It was the fact that I left it on the display as it was.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a thumbtack puller that can easily and reliably remove not only a normal thumbtack but also a thumbtack with a removed head.

[0006]

Therefore, the thumbtack punch according to the present invention has a scissors-like shape in which the front-side clamping portion can be opened and closed by the gripping operation of the grasping portion, and the bottom surface of the clamping portion is flush with the left and right sides.
So that the wall thickness gradually decreases toward the tip
The rear end of the inclined surface is used as a fulcrum of the lever.
The serial nip is subjected head that can be inserted between the pushpin foot can be inserted leg portion groove and thumbtack head and the wall at its closed state to the tip formed in the rear of the head portion receive the In the closed state
Entire foot portion holding surface capable of close contact with each other is formed, the wall surface of the pushpin is receiving the head in the head receiving or foot pinching the foot
The gist of the present invention is that the pinch is held by the holding surface and can be pulled out by leverage with the rear end of the bottom of the pinch as a fulcrum.

The overall shape of the thumbtack puncher is preferably in the form of Western scissors as shown in the following embodiment in consideration of ease of use, but may be of course in the form of Japanese scissors. Further, the head support of the sandwiching portion may be an inclined surface shown in the following embodiment, but may be a substantially flat surface. In this case, the top edge of the head receiver is preferably formed sharp so that it can be easily inserted into a small gap between the wall surface and the head of the thumbtack. Further, it is preferable to provide a spring member on the grip so that it can be opened lightly. Here, the wall surface refers to a surface on which a thumbtack is pushed, such as an exhibition board.

[0008]

[Action] When pulling out a normal thumbtack, grasp the gripping part, close the front side pinching part, insert the thumb of the thumbtack into the foot groove of the head holder, and hold the head holder with the head and wall of the thumbtack. When the grip portion is pressed downward, the head receiver is lifted upward with the rear portion of the sandwiched portion as a fulcrum, and the thumbtack comes off the wall surface.

On the other hand, when the thumbtack is old and its head is removed and only the foot remains on the wall, the pinch is opened, the foot of the thumbtack remaining between the foot holding surfaces is inserted, and the grip is grasped. The pin portion of the thumbtack may be pinched and pressed downward as it is, and in either case, the thumbtack is pulled out.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific examples shown in the drawings. 1 to 3 show a pushpin removal according to an embodiment of the present invention. In the figure, a pushpin 1 has a Western scissors shape, a pinch piece 2 on the tip side, and a grip handle 3 on the rear half.
Is formed, and the distal-side holding piece 2 is opened and closed by the gripping operation of the grip handle 3.

A step of a predetermined size, for example, about 1 to 1.5 mm, is formed on the inner surface of the distal end of the pinch 2 so as to face the pin. The portion 40 constitutes the leg groove 20 which can be inserted. In addition, pinch piece 2
The bottom surface 21 of the front end is provided to be inclined with respect to the longitudinal direction, and its rear end edge is a fulcrum a.

Further, the upper surface of the tip of the pinch piece 2 forms a head support 22 for the thumbtack 4, which is inserted between the head 41 of the thumbtack 4 and the display board (wall surface) 5. It has become. The head receiver 22 may have a flat shape as shown in FIG.

A flat foot holding surface (foot holding portion) 23 behind the head support 22 is provided on the inner surface of the distal end portion of the holding piece 2.
Is formed, and the foot holding surface 23 is capable of securely holding the foot 40 of the thumbtack 4 by the gripping operation of the grip handle 3. The foot holding surface 23 does not need to be the entire surface in the height direction of the inner surface of the distal end portion of the holding piece 2 and may be formed to a height of about 1 to 2 mm. 4 can be clamped, and the operation is further facilitated.

Next, the function and effect will be described. When the thumbtack 4 inserted into the display board 5 is pulled out, as shown in FIG. 2A, the grip piece 3 is closed and the pinch piece 2 is closed. 2 foot grooves 20
While inserting the foot portion 40 of the thumbtack 4, the tip head receiver 21 of the sandwiching piece 2 is inserted under the head 41 of the thumbtack 4 (see the arrow A in FIG. 2). When the head 41 of the thumbtack 4 is sufficiently received by the head receiver 21, the grip handle 3 is pressed downward as shown in FIG. 2B (see arrow B in FIG. 2). Then, the head support 21 moves upward with the rear end edge of the bottom surface of the sandwiching piece 2 as the fulcrum a, and the thumbtack 4 can be lightly pulled out by leverage (see arrow C in FIG. 2).

When the head 41 is removed and only the feet 40 remain on the display board 5, as shown in FIG. 3 (a), the sandwiching piece 2 is opened to display the feet 40 of the thumbtack 4. When the portion protruding from the plate 5 is inserted between the foot holding surfaces 23 and the grip handle 3 is firmly gripped (see the arrow D in the figure), the foot 40 of the thumbtack 4 can be held. 3), the grip handle 3 may be pressed down as it is (see arrow B in FIG. 3), and the foot portion 40 of the thumbtack 4 can be lightly pulled out of the display board 5 by leverage (arrow in FIG. 3). E).

Therefore, the work is simpler and more reliable than when using conventional pliers, and the palm of a person involved in the display work or the fingertip may be caught on the foot portion 40 of the thumbtack 4 where the finger rests, resulting in injury. Can be eliminated.

[0017]

As described above, according to the present invention, not only ordinary pushpins but also old pushpins having a removed head can be easily and reliably removed from the wall surface by leverage.
