DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a locking piece attaching device used for attaching tags such as price tags to products or connecting two or more articles using a locking piece.

The locking piece is a so-called "tag pin", and as shown in FIGS. 1 and 2, it is composed of a head 1 for attaching a price tag, a filament 3, and a horizontal bar 2 that passes through clothing, etc. The locking piece t consisting of these three parts is planted in a comb shape on the connecting rod 5 via the connecting part 4, and is integrally molded as a locking piece assembly T from a synthetic resin such as nylon or polypropylene. . This locking piece assembly T has one connecting rod 5.
20 to 50 locking pieces t are planted against each other.
In addition, in the locking piece assembly T, the interval l between the locking pieces t on the connecting rod 5 is normally arranged at around 2 mm for the sake of manufacturing the mold and for loading and driving into the mounting device. .

As shown in FIG. 3, the attachment device A for driving the locking piece t is attached to a grip portion 10a of a substantially pistol-shaped main body 10.
An injection lever 11 is attached rotatably about a shaft 11a, and is normally in the position shown in FIG. 3, being pressed by the intermediate lever 12 and locked to the grip portion 10a by a stopper 11b. When the finger rest 11c of the injection lever 11 is grasped, the injection lever 11 rotates about the shaft 11a in the direction of arrow P, and the locking piece injection portion 10b is slidably installed inside the injection lever 11 via the intermediate lever 12. Slider 13 is rapidly moved in the direction of arrow Q.
As a result, the push-out rod 14 protruding from the slider 13 rushes into the horizontally grooved hollow needle 15.

Further, a guide groove 16 is provided behind the mounting position of the hollow needle 15 of the locking piece injection portion 10b so as to cross the course of the push rod 14. The intermediate lever 12 is located inside the injection section 10b.
A slide bar 19 is provided which moves in synchronization with the movement of the slider 13 due to the rotation of the slider 13, and this slide bar moves every time the injection lever 11 is gripped, and the slide bar 19 moves in synchronization with the movement of the slider 13. 18 to move the locking piece connecting rod 5 inserted into the guide groove 16 one locking piece at a time in the direction of arrow R. Furthermore, a locking piece t inserted into the guide groove 16 is provided on the side of the guide groove 16 on the hollow needle 15 side.
A cutting tooth 17 is attached to a position facing the connecting portion 4 of the locking piece t, and when the horizontal bar 2 is injected into the hollow needle 15 by the pushing rod 14,
The cutting teeth 17 separate the connecting portion 4 from the connecting rod 5.

The configuration of the conventional locking piece attaching device A is as described above. When attaching a tag such as a price tag to clothing using the locking piece T, first attach the tag 6 to the clothing as shown in FIG. Place it on top of 7, this tag 7
The hollow needle 15 of the attachment device A is passed through the attachment hole 6a of the attachment device A and later penetrated to the back side of the clothing 7. Next, in this state, the injection lever 11 of the grip part 10a of the mounting device A is
Once this is grasped, the pushing rod 14 injects the horizontal bar 2 of the locking piece t through the hollow needle 15 onto the back side of the garment 7. After this, when the hollow needle 15 is pulled out, the horizontal bar 2 of the locking piece t is located on the back side of the garment 7, and the filament 3 is attached to the hole 7a made in the garment 7 by the hollow needle 15 and the tag 6. The tag 6 is inserted through the attachment hole 6a, and the head 1 is positioned on the front side of the clothing 7, thereby locking the tag 6 so that it does not come off.

In this way, the conventional locking piece attaching device A can be used to easily attach a tag 6 on clothing, etc. with a price tag, product name, etc. written on it.
It is very convenient because it can be attached.

However, although the conventional locking piece attaching device is very easy to use from a direction perpendicular to the object to which the piece is attached, it is difficult to use from an oblique direction. In addition, in recent years, there has been a desire to suture two sheet-like objects using a conventional locking piece attachment device. The work was troublesome.

Therefore, the inventor of the present invention utilized the conventional locking piece attaching device main body to develop the device in order to meet the needs of using it diagonally and to sew two sheet-like objects together. A locking piece attachment device of the present invention has been devised.

In order to achieve the above object, the present invention changes the shape of the horizontally grooved hollow needle that is continuously attached to the locking piece injection port of the locking piece attachment device, and changes the configuration of the push-out rod in conjunction with this change. ing.

Embodiments of this invention will be described below with reference to the drawings.

FIG. 5 is a perspective view of the horizontally grooved hollow needle 20 of the locking piece attachment device B of the present invention. In this invention, the hollow needle 20 is formed to be curved in the direction of the lateral groove 20a. The curved shape of the hollow needle 20 of the present invention may be such that the intermediate portion 20b of the needle is curved as shown in FIG. 6, or only the tip portion 20c of the needle may be curved as shown in FIG.

In this invention, since the hollow needle 20 is configured as described above, the push rod 21 that injects the locking piece t through the hollow needle 20 is made of an elastic material so that it can be deformed along the shape of the hollow piece 20. However, in order to make the stiffness as strong as possible, the diameter t is set so that the push rod 21 can escape from the lateral groove 20a of the hollow needle 20 as shown in FIGS. 8A and 8B. The horizontal groove 20a
The extrusion rod 21 is made of a strong material with slight elasticity. The extrusion rod 21 in the example of FIGS. 8A and 8B has a narrow diameter so that it escapes from the lateral groove 20a to the outside, but as shown in FIGS. 9A and 9B, a part of the extrusion rod is It is also possible to use a parallel push-out rod 22 with a width u thinner than that shown in FIG. In addition, only the tip of the push-out rod that comes into contact with the locking piece t has the same shape as before, and only the part that protrudes from the horizontal groove 20a of the hollow needle 20 is made smaller in diameter than the width of the horizontal groove 20a as described above, or is shaped like a parallel thin plate. Forming the first
