Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fastener used for pinning brooches, insignia, etc.

This type of locking device is used by engaging the pointed end with the head, so the needle is not exposed and is called a safety pin, but each time it is used, the pointed end is It is cumbersome to handle as it has to be repeatedly disengaged and engaged again, and for safety reasons, it is necessary to keep the pointed end engaged with the head even when not in use.

Therefore, there is a risk of puncture if not handled with care.
Another drawback is that it is very difficult to use when wearing gloves.

The present invention solves the above-mentioned drawbacks, and its purpose is to provide a fastening device for brooches, badges, etc. that can be safely and easily used by anyone, and has a J-shaped planar shape. A straight cylindrical member is cut out from the head 1 and a member in which an insertion rod 3 is continuously provided at one end of the U-shaped elastic part A and a needle rod 4 is continuously provided at the other end. A section B is provided, and the cylindrical section B
An elongated hole 2 that communicates with the inside and outside in the longitudinal direction is provided, and a hook-shaped locking hole 2' is provided at the rear end of the hole 2, and a convex portion that engages with the elongated hole 2 and the locking hole 2'. 3' is slidably but irremovably fitted into the cylindrical part B, and the convex part 3' at one end locks the other pointed end 4' of the insertion member 3. Hole 2
The gist of this invention is a locking device such as a brooch or an insignia, which is characterized in that the locking device 5 is configured to come into elastic contact with a locking receptacle 5 recessed approximately in the center of the head 1 through an elastic portion A.

In the illustrated embodiment, the head 1 is formed in a plane or in a J-shape.
A cylindrical part B is provided in the straight part of the cylindrical part B, and an elongated hole 2 that communicates with the inside and outside of the cylindrical part B is opened along the longitudinal direction at the end of the straight part, and at the rear end of the elongated hole 2. The insertion rod 3 is slid into the cylindrical portion B, and the locking hole 2' is continuous and has a notched shape, and the insertion rod 3 has a convex portion 3' at one end that engages with the elongated hole 2 and the rear end locking hole 2'. It can be inserted and inserted in a way that is possible and cannot be removed.

The insertion rod 3 has a substantially U-shaped plane and has an elastic part A between the valves, and when the convex part 3' at one end is located in either the locking hole 2' or the elongated hole 2, the elastic part A is The needle rod 4 is in elastic contact with the hole wall due to the force, so that the pointed end 4' of the needle rod 4 is always elastically in contact with the locking receptacle 5 formed at the contact point of the head 1 (see each figure). reference).

Note that the tip of the needle rod 4 does not protrude beyond the front end of the head 1 when the insertion rod 3 is extended relative to the head 1, and in this position, the tip of the protrusion 3
' is engaged in the locking hole 2' (Fig. 2, Fig. 5, Fig. 6)
.

In the above configuration, to use this, rotate the insertion rod 3 about the axis so that the protrusion 3' of the insertion rod 3 comes out of the locking hole 2', and slide it in the direction of the head 1. Point 4'
protrudes from the head 1, so the needle rod 4 can be attached to clothing C.
The needle can be inserted from the direction in which it is in contact with (the opposite direction to Fig. 1), and if the insertion rod 3 is reversed using the needle rod 4 as the axis and then the insertion rod 3 is extended (Figs. 4 and 5), the needle rod can be inserted. 4 is located inside the head 1, so it can be attached without being pulled out.

In the case of removal, it can be easily removed by placing the locking tool in the orientation shown in FIG. 3 and pulling out the insertion rod 3.

The present invention has the above-described configuration, in which the pointed end 4' of the needle rod 4 comes into elastic contact with the locking receptacle 5 recessed in the approximate center of the head 1.
slides the length of the slotted hole 2, so the pointed end 4' is aligned with the head 1.
When the head 1 is pulled, the convex portion 3' and the locking hole 2' are engaged, and this locking is released and the needle rod 4 is inserted.
It can be easily removed by pulling it out of clothing, etc. Therefore,
Unlike conventional safety pins, it can be attached and removed without having to remove the needle rod, and the hassle of opening and closing the needle is not required, which not only significantly improves operability but also improves safety. Since it is always elastically in contact with the head, it does not rattle and can be used with appropriate moderation.
