実 施 An embodiment of the present invention will be described with reference to the drawings. 1 is a partially cutaway sectional view for explanation showing a basic configuration of a connecting pin for an adjustment piece according to the present invention, FIG. 2 is a partially cutaway sectional view for explanation showing Modification Example 1, and FIG. And FIG. 4 is a perspective view showing another embodiment. FIG. 5 is a perspective view showing a part of a watch band including an adjustment piece, and FIG. 6 is an exploded perspective view showing the same.

An adjusting piece connecting pin 10a (hereinafter, referred to as a "connecting pin 10a") shown in FIG. 1 has a cylindrical pin main body 1 made of stainless steel and a locking body 3 made of silicone rubber wound around both ends. It is attached as follows. As a modified example 1 of the connecting pin 10a having this configuration, an adjusting piece connecting pin 10b (hereinafter referred to as a "connecting pin 10b") shown in FIG. is there. Although the cut groove 2 is cut into a square shape in the drawing, the cut groove 2 is not limited to this, and may be provided with an arc shape or a tooth-shaped notch on the bottom surface. An engaging body 30 made of silicon rubber whose surface is bulged is firmly wound around the cut grooves 2.

As a second modification, the connecting pin 10c for an adjustment piece (hereinafter referred to as a “connecting pin 10c”) shown in FIG. 3 is made of silicon rubber having a surface bulging at both ends of the pin body 1 and having a small outer end. An integrally formed locking body 31 is firmly attached, and is fixed to both ends of the pin main body 1 by, for example, an adhesive and a reinforcing piece 32 shown in the figure.

係 止 Here, the locking body may be not at both ends of the pin body 1 but may be attached as shown in FIGS. In addition, the method of attaching the locking body is not limited to this. FIG. 4A shows an example in which the locking bodies 33 are widely wound around the center of the pin body 1, and FIG. 4A shows an example in which a plurality of the locking bodies 34 are wound in parallel. In addition, FIG. 4C shows that the locking body 35 is not wound around the pin body 1 but is attached to the pair so as to sandwich the pin body 1. FIG. The body 36 is attached regularly or irregularly at a spot. In short, the locking body only needs to be attached to the pin body so that the pin body is pressed against the inner wall of the pin hole when the pin body is inserted into the pin hole.

FIG. 5 shows a part of the watch band 5 including the adjustment piece 4, and an example of a method of connecting the adjustment piece 4 will be described with reference to FIG. Here, the description will be made using the connection pins 10a, but the same applies to the connection pins 10b and 10c and the connection pins shown in FIG.

In the adjustment pieces 4a and 4b adjacent to each other, the convex portion 41 of one adjustment piece 4a is fitted into the concave portion 42 of the other adjustment piece 4b, and the pin holes 40 and 43 are aligned with each other. When the connecting pin 10a is passed through 43, the adjacent adjustment pieces 4a and 4b are connected via the connecting pin 10a. In this manner, the adjustment pieces that are adjacent to each other are sequentially connected to form the watch band 5.

That is, the diameter of the outer diameter of the locking body 3 in the connecting pin 10a is φA, and the diameter of the pin body 1 is φB. When the diameters of the pin holes 40 and 43 of the adjustment pieces 4a and 4b are φC, by satisfying the relationship of φA> φC> φB, the locking body 3 is pressed tightly against the inner wall of the pin hole 43. The connecting pin 10a is firmly fixed in the pin hole 43. As a result, the adjustment pieces 4a and 4b adjacent to each other can secure a strong connection state.

In addition, a tip having an extremely thin body, for example, a tip shaft barrel of a mechanical pencil is inserted into one of the connection pin holes 43 to which the connection pin 10a is fixed, and a small amount of the connection pin 10a is moved in the direction of the other pin hole. The connection pin 10a may be pushed out from the other side by applying a pressing force, and the connection pin 10a can be easily removed. Then, the connection of the adjustment pieces can be disconnected, and the number of the adjustment pieces can be adjusted to match the length of the body part.

Next, in order to connect the adjustment pieces 4a and 4b adjacent to each other, the respective pin holes 40 and 43 are aligned, and one of the connection pins 10a is inserted from one of the aligned pin holes 40 and 43. At the time of insertion, the diameter A of the locking member 3 made of silicone rubber, which is an elastic body, is compressed. The inserted connecting pin 10 a is fixed in the pin hole 43 by the locking body 3 being pressed against the inner wall of the pin hole 43 by its elasticity. Note that the adjustment pieces 4 to be connected are not limited to the illustrated example, and various adjustment pieces can be used.

In this embodiment, the separation and connection of the adjustment pieces have been described, but it is needless to say that the invention can be applied to the case of an adjustment piece and a jumpsuit piece.
