Description

[Detailed description of the invention] The present invention relates to an improvement of a retaining pin for attaching to fabrics such as clothing and bedding, and it is possible to make the attaching and detaching operations extremely easy and quick. As well as being able to
The purpose is to ensure that the needle sticks.

That is, the present invention is provided with a main body frame opening an elongated hole, an operating rod that connects a base and a sliding piece that can be fitted into the elongated hole in a substantially oval shape, and the elongated hole has a sliding piece. is inserted into the elongated hole so as to be constantly biased toward the opening through the action of a spring inserted therein. The hook rod is pivotally connected between the rear part of the main body frame and one end of the base via two annular parts, and a window hole is opened at a position near one end of the base in correspondence with the hook part. The gist of this document is as follows.

Hereinafter, specific embodiments of the present invention will be described with reference to the illustrative drawings.

In each drawing shown in Fig. 1 to Fig. 4, 1 is the main body frame, 2
1 and 2 respectively show operating rods attached to the main body frame 1 so as to be pressable and operable.

Therefore, the main body frame 1 has a disk-like overall shape, and a blind elongated hole 3 is bored in the main body frame 1 in the diametrical direction, and the opening 3' is formed in the peripheral wall. It is recommended that it be installed in some areas.

18 to the rear of the elongated hole 3, that is, to the opening 3'.
A tongue piece 4 is provided at a position that is 0 degrees out of phase with each other, and a small hole 5 for engaging a hook rod 7, which will be described later, is inserted through the tongue piece 4.

Reference numeral 7 is the above-mentioned hook rod, in which one wire rod is bent to form two annular portions 6, 6' in an approximately figure 8 shape, and from one end of the annular portion 6', an approximately figure 3 shape is formed. Bent hook part 8
It is formed by extending it as one piece.

The hook rod 7 is rotatably connected to the small hole 5 through the annular portion 6 on one side.

On the other hand, the operating rod 2 has a base plate 10 and a sliding piece 9 formed with approximately the same diameter as the elongated hole 3 so that it can be inserted into the elongated hole 3. A space 17 for enclosing the base plate 1' is provided continuously in an approximately O-shape, while a small hole 11 for connecting the hook rod 7 is provided at one end of the base plate 10. A window hole 8 for inserting the hook portion 7' is located near the hole 11.
It is a warning to open the door.

Therefore, the operating rod 2 has its sliding piece 9 slidably inserted into the elongated hole 3 opened on the main body frame 1 side, and the spring 12 is interposed in the elongated hole 3. , the actuating rod 2 appears to be constantly biased toward the opening 3'.

Further, the other annular portion 6' of the hook rod 7 is engaged with the small hole 11 provided at one end of the base plate 10, while the tip of the hook portion 7' is placed in a position corresponding to the window hole 8 portion. It shall be provided as it exists.

The hook portion 7' is normally inserted into the window hole 8 through the biasing action of the spring 12.

In the above embodiment, the body frame 1 is formed into a substantially cylindrical shape, but the shape is not limited to this in any way; for example, it is also possible to use a rectangular parallelepiped, a polygonal prism, etc. .

Next, its effect will be explained.

FIG. 3 shows the normal state, that is, the state in which the retaining pin according to the present invention is not yet engaged with the fabric a, which is the object to be engaged, and the state where the retaining pin according to the present invention is engaged with the fabric a, as described below. Indicates the current state.

In this normal state, the sliding piece 9 fitted into the elongated hole 3 is urged toward the opening 3' through the action of the spring 12, as shown in FIG. The hook portion 7' of the rod 7 is in a state of being wedged into the window hole 8 due to the biasing action of the spring 12.

However, if the head 2' of the operating rod 2 is pressed in this normal state, the sliding piece 9 will be pushed into the elongated hole 3 against the biasing action of the spring 12. It is.

The base 10 also moves in the same direction as the sliding piece 9, and through the movement of the base 10, the base 10 moves in the same direction as the sliding piece 9.
0 and one end of the main body frame 1 via a pair of annular parts 6, 6', the hook rod 7 pivots in the moving direction of the base 10 with one annular part 6 as a fulcrum. It rotates to the left in FIG. 3, and the tip end hook 7' comes off from the window hole 8.

That is, the state shown in FIG. 4 is obtained. However, when the base 10 of the retaining pin is in contact with the surface of the fabric a as shown in FIG. The sliding piece 9 of the rod 2 is pushed by the biasing action of the spring 12 inside the elongated hole 3 toward the opening 3', while the base 10 also moves in the same direction as the sliding piece 9. It will become.

Then, due to the movement of the base 10, the hook rod 7 rotates again using the annular portion 6 as a fulcrum in the opposite direction, that is, to the right in FIG. It will be inserted into the window hole 8 in the state where it is pierced.

In other words, the fabric a can be secured in the state shown in FIG.

The present invention has the above-mentioned configuration, and as described above, the main body frame 1 which opens the elongated hole 3, the sliding piece 9 that can be fitted into the elongated hole 3, and the base 10 are formed in an approximately oval shape. A sliding piece 9 is inserted into the elongated hole 3 so as to be constantly biased toward the opening 3' through the action of a spring 12. There are two continuous annular parts 6, 6' and a U-shaped hook part 7' to form a hook rod 7, and the hook rod 7 is connected to the main body frame 1 through the two annular parts 6, 6'. Posterior and base 10
At the same time, the hook part 7' is connected to the base 10 at one end.
Since it is provided so that it can be inserted into a window hole 8 opened at one end of the band position, it can be operated very easily by simply pressing the head 2' of the operating rod 2 and releasing the pressed state. It has now become possible to make the hook portion 7' stick to the fabric a, and to do so reliably.

Since the present invention has the above-mentioned mounting structure, it can be used for a variety of purposes, such as being used as a fixing pin for futon covers, sheets, etc., as a button, and as a patch. The practical effects in this regard are extremely large.
