Abstract

PROBLEM TO BE SOLVED: To provide an easily handleable safety pin made of a synthetic resin without danger. SOLUTION: For this safety pin 1 made of a synthetic resin, a rod part 4 where a locking part 6 in a spindle shape is formed is passed through a punch hole pierced on a mount or the like and cloth, etc. Then, when the rod part 4 is slightly pulled toward a fit-in part 5, the locking part 6 in the spindle shape is fitted into a fit-in hole part 8 and the extended end part 4a of the rod part 4 is fitted into a groove part 9 respectively, by the elasticity of a bend part 2, the rod part 4 is pulled back and a locking step part 7 is abutted to a step part 10 and locked. At the time, the neck part of the locking part 6 in the spindle shape enters the lower side of fall-out stopping pieces 12 formed on the hole edge 11 of the fit-in hole part 8. In this state, since pull-back force by the bend part 2 acts onto the rod part 4, the locking part 6 does not fall out from the fit-in hole part 8 to the side part of the fit-in part 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety pin made of synthetic resin.

[0002]

2. Description of the Related Art Conventionally, a safety pin is formed by winding or bending a metal wire to form an elastic portion, and providing a hook portion made of a metal plate so as to face the elastic portion and continuously forming the elastic portion. I was trying to hook the needle.

[0003]

However, if a metal safety pin is used, it must be handled with care.
The needle is stuck. Further, unless the puncture needle is hooked on the hook, it is inconvenient to handle because it cannot be put together in a box for sale or displayed. The present invention has been made to solve the above problems, and an object of the present invention is to provide a safety pin made of synthetic resin which is easy to handle and is not dangerous.

[0004]

SUMMARY OF THE INVENTION To achieve the above object, a safety pin made of synthetic resin according to the present invention has a rod portion formed by extending both ends of a substantially U-shaped curved portion, and one rod portion. A fitting portion formed at the tip of the rod so as to face the curved portion, a spindle-shaped locking portion formed at the extension end of the other rod portion, and a locking step provided between the locking portion and the extension end. And a fitting hole into which the locking part is fitted from a side surface of the fitting part,
A groove for inserting the extended end of the other rod from the side surface is formed, and after the engaging portion is inserted into the insertion hole and the extended end is inserted into the groove, respectively, the elastic force of the curved portion is applied. When the other rod is pulled back toward the curved portion and the locking step contacts the step between the fitting hole and the groove, the locking part moves from the fitting hole. It is characterized in that a retaining piece is formed at a hole edge of the fitting hole portion so as not to come out of the side portion of the fitting portion.

[0005]

With the synthetic resin safety pin having the above-described structure, when the spindle-shaped locking portion is pulled to fit into the fitting hole portion of the fitting portion, and the extended end portion of the rod portion is fitted into the groove portion, The rod portion is pulled back toward the bending portion side by the elasticity of the bending portion, and the locking step portion of the locking portion contacts the step portion between the fitting hole portion and the groove portion. At this time, since the retaining piece is formed on the hole edge of the fitting hole portion, the locking portion does not slip out of the fitting hole portion to the side portion of the fitting portion. Therefore, the function of the conventional safety pin can be sufficiently fulfilled, and since it is an integrally molded product made of synthetic resin, it can be safely handled even when the locking portion is disengaged from the fitting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a synthetic resin safety pin (hereinafter referred to as a safety pin) 1, and FIG.
2 is a front view of a state in which it is fitted in, FIG. 3 is a sectional view taken along the line AA in FIG. 2, and FIG. 4 is an explanatory view showing an example of a use state.
As shown in FIG. 1, the safety pin 1 of the present invention is an integrally molded product made of synthetic resin. Both ends 2a of the substantially U-shaped curved portion 2,
2b is extended to form rods 3 and 4, respectively. A fitting portion 5 having a substantially semicircular shape is formed at the tip of one of the rod portions 3 so as to face the bending portion 2. The other rod portion 4 forming the insertion pin portion of the safety pin 1 extends in a slightly opened and closed manner away from the fitting portion 5, and its extended end portion 4
A spindle-shaped locking portion 6 is formed on a. A locking step 7 is formed on the neck 6a between the locking portion 6 and the extension end 4a.

The fitting portion 5 having a substantially semicircular shape has a fitting hole portion 8 into which a spindle-shaped locking portion 6 is fitted from the side surface thereof, and an extended end portion 4a of the rod portion 4 continuing from the locking portion 6 as a side surface. The groove portion 9 that is fitted in from is formed continuously. A step portion 10 is formed between the fitting hole portion 8 and the groove portion 9. Then, between the hole edge 11 of the fitting hole portion 8 that is continuous with the groove portion 9 and the step portion 10, there are formed retaining pieces 12, 12 that protrude toward the fitting hole portion 8 side. The retaining pieces 12 and 12 prevent the neck portion 6a of the spindle-shaped locking portion 6 from coming into contact with the retaining portion 12 and coming out of the insertion hole portion 8 to the side portion of the insertion portion 5. Further, a string passing hole 13 through which a string such as a price tag is inserted is formed in the fitting portion 5 adjacent to the fitting hole portion 8.

The safety pin 1 has a rod portion 4 having a spindle-shaped engaging portion 6 formed therein, which is passed through a punch hole or a cloth punched in a mount or the like. Then, the rod 4 is slightly pulled toward the insertion portion 5, the spindle-shaped locking portion 6 is inserted into the insertion hole portion 8 and the extended end portion 4a of the rod portion 4 is inserted into the groove portion 9, respectively. Due to the elasticity, the rod portion 4 is pulled back and the locking step portion 7 becomes the step portion 1.
0 is contacted and locked. At this time, the spindle-shaped locking portion 6
The neck portion 6a of the insertion portion enters the lower side of the retaining pieces 12, 12 formed on the hole edge 11 of the fitting hole portion 8 (see FIG. 3). In this state, since the pullback force of the bending portion 2 acts on the rod portion 4, the locking portion 6 does not slip out of the fitting hole portion 8 to the side portion of the fitting portion 5.

As described above, the safety pin 1 of the present invention can perform the same function as the conventional safety pin made of metal, and as shown in FIG. 4, the string 14 is passed through the string passing hole 13 and the price tag 15 and the like. It can also be used to suspend. In addition, since it is an integrally molded product made of synthetic resin, and a spindle-shaped engaging portion 6 is formed at the tip of the rod portion 4 which is a piercing pin portion, a large number of safety pins 1 are handled at once. Even if it does, it has the advantage that it will not get stuck.
