DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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 a hook portion made of a metal plate is provided opposite to the elastic portion, and is formed continuously with the elastic portion. I was trying to stop the needle.

[0003]

However, if metal safety pins are used, they must be handled with care.
The needle is stuck. Further, if the puncture needle is not hung on the hook, there is a problem in that it is inconvenient to handle, for example, it cannot be put together in a box for sale or displayed. The present invention has been made to solve the above problems, and has as its object to provide a synthetic resin safety pin that is easy to handle and has no danger.

[0004]

According to the present invention, there is provided a safety pen made of synthetic resin according to the present invention, comprising: a rod portion formed by extending both ends of a substantially U-shaped curved portion; A fitting portion formed at a tip of the fitting portion so as to face the curved portion, a locking hook formed at a side portion of an extension end of the other rod portion, and a vertically long portion formed on an inner surface of the fitting portion facing the curved portion. A safety groove made of synthetic resin, and a fitting opening for fitting an extension end of the other rod portion formed on one upper side of both side walls constituting the fitting groove. The other rod portion whose end is fitted into the fitting groove,
And a locking step for locking the locking hook when pulled back toward the bending portion by the elasticity of the bending portion.

[0005]

The safety pin made of synthetic resin having the above structure, when the locking hook formed on the side of the extended end by pulling the other rod portion is fitted into the fitting groove from the fitting opening, the bent portion of the curved portion is formed. The rod portion is pulled back to the curved portion side by the elastic force, the locking hook is locked to the locking step portion, and the other rod portion is opened by the force to open the other rod portion. Is in contact with Therefore, the extended end of the other rod does not fall out of the fitting groove. Therefore, the function of the conventional safety pin can be sufficiently fulfilled, and since it is an integrally molded product made of a synthetic resin and does not have a sharp portion, it can be safely handled.

[0006]

Embodiments 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 “safety pin”) 1, and FIG.
FIG. 3 is a sectional view taken along 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 formed by extending the rod portions 3 and 4, respectively. A substantially semicircular fitting portion 5 formed opposite to the curved portion 2 is formed at the tip of one of the rod portions 3. The other rod portion 4 forming the insertion pin portion of the safety pin 1 is slightly opened and slightly extended away from the insertion portion 5 and extends therefrom.
A locking hook 6 is formed on the side of "a". Extension end 4a
By forming the bent portion 7 in the rod portion 4, the corresponding interval with the rod portion 3 is reduced. Further, the thickness of the rod portion 4 from the bent portion 7 to the extended end portion 4a is formed thin.

The substantially semicircular fitting portion 5 has a curved portion 2
A vertically long insertion groove 8 and a string passing hole 9 are formed on the inner surface facing the. The fitting groove 8 is formed by both side walls 10 and 11 of the fitting portion 5. The side wall 10 on the near side in FIG.
The upper half and the half facing the side wall 11 on the curved portion 2 side are formed in a shape removed. The insertion opening 12 is formed by removing the upper half. A hole 13 is formed in the side wall 11 by removing a portion corresponding to the fitting opening 12 to the string passing hole 9. A locking step 14 for locking the locking hook 6 is formed below the linear hole edge 13a of the hole 13.

The safety pin 1 passes a rod 4 having a reduced thickness toward the extension end 4a through a punch hole or a cloth formed in a mount or the like. When the rod portion 4 is slightly pulled toward the fitting portion 5 and the extended end portion 4a is fitted into the fitting opening 12, the resilient force of the bending portion 2 causes the rod portion 4 to be pulled back and the locking hook 6 to be locked. It is locked to the step portion 14. At this time, the rod 4
Is extended by the elastic force of the curved portion 2, and the extended end portion 4 a is in contact with the groove bottom of the fitting groove 8. Therefore,
The extended end 4a of the other rod 4 does not fall out of the fitting groove 8.

As described above, the safety pin 1 of the present invention can perform the same function as a conventional metal safety pin, and also, as shown in FIG. Can also be used to suspend In addition to being an integral molded product made of synthetic resin,
Since the rod portion 4 serving as the piercing pin portion does not have a sharp portion, there is an advantage that even if a large number of the safety pins 1 are handled at a time, they are not pierced.
