Description

[Detailed description of the invention] This invention combines the joining surface of the lower surface of the base plate with the display plate,
This is a multi-purpose safety pin that can be attached to the back of a pendant, etc. The pin body has a needle protruding from one end of a coil-shaped winding part and a mounting leg protruding from the other end, and A base plate made of synthetic resin or the like is provided with a winding part protection protrusion and a hook, into which the coiled winding part is almost tightly inserted, and the base plate is assembled and engaged without the use of adhesive. The pin body has a structure that allows the base to be connected to the back of the display plate by hooking the prick on the pin body to the hook on the base, and its purpose is to simplify the assembly of the pin body and base plate. We offer a multi-purpose safety pin.

Conventionally, this type of safety pin has a base plate a with a protrusion for protecting the winding part and a hook C facing each other on the surface, as shown in FIG.
Then, insert the coiled winding part g of the pin body f into the fitting hole d formed in the center of the protective protrusion, fit the mounting leg into the fitting opening groove e on the back of the base, and then A plate material j, such as a shallow cap, is fixed on the back side with adhesive, and then the needle i is hooked to the hook C, and the assembly required joining the plate material j with adhesive, so the number of man-hours was reduced. Not only is it necessary to increase the number of parts, but also the thickness of the base plate a is substantially increased.

The present invention eliminates this drawback. An embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a metal pin body, which is formed into a normal shape with a pricking needle 3 protruding from one end of a coil-shaped winding portion 2 and a small attachment leg 4 protruding from the other end. The insertion part 5 is bent upward at the end of the insertion part 5, and the mounting leg 4 is inserted from the upper end of the insertion part 5.
An engaging jaw rod 6 extending parallel to the engaging jaw rod 6 is provided.

The base plate 11 is made of hard synthetic resin and is molded into an elongated shape, and has winding portion protection protrusions 12 and hooks 14 facing each other on its upper surface, a bonding surface 15 on its back surface, and the protective protrusions 1
2, a fitting hole 13 is formed in the center of the hole 13, which is transparent to the back surface, and on the top surface, a tip in the direction of the hook 14 is provided in the protective protrusion 12 so as to communicate with the upper end side of the fitting hole 13, and a joining surface is formed. 15 is formed with a fitting groove 16 communicating with the fitting hole 13, and an insertion hole 17 extending to the surface is provided at the end of the groove 16.

The through hole 17 is formed between the protective protrusion 12 and the hook 14, and a locking groove 18 is provided on the surface so as to communicate with the through hole 17.

In this embodiment, as shown in FIG. 4, the pricking needle 3 of the pin body 1 is passed through the fitting hole 13 from the bottom surface of the base plate 11, and at the same time, the engaging head 6 is passed through to the upper side of the through hole 17, and then the pin body 1 is wound. When the rotating part 2 is passed through the fitting hole 13 and fitted, the engaging head 6 is latched to the latching opening groove 18, and the insertion part 5 is passed through the through hole 17.
At the same time as the mounting leg 4 is fitted into the fitting opening groove 16, the pricking needle 3 projects upward from the winding portion protection projection 12.

Therefore, the tip of the needle 3 can be removed from the side of the hook 14 and hung freely (FIG. 5).

As clarified from the above explanation, the present invention provides an engagement head 6 forming the end of the mounting leg 4 of the pin body 1 to the base plate 11.
It protrudes from the upper surface and is latched into the latching opening groove 18 on the upper surface, and the end of the needle 3 is latched onto the hook 14 on the upper surface of the base plate 11. No adhesive is used for this assembly. There is no need to attach a plate material such as a cap that presses the mounting leg 4 from the back side with adhesive to the back side of the base plate 11, and this multi-purpose safety pin can be used without the manufacturer's instructions for display plates, pendants, etc. There is no danger that the pin body 1 will come off the base plate 11 until it reaches the base plate 11, and by pasting a display plate or the like on the joining surface 15 of the base plate 11, the pin body 1 will remain attached to the base plate even if the needle 3 is removed from the hook 14. 11, and although there is a disadvantage that the engaging head 6 is exposed on the surface of the base plate 11, there is no risk that this will harm the design of the display plate, pendant, etc., and the safety pin manufacturer This makes the production of multi-purpose safety pins extremely advantageous.
