Description

TECHNICAL FIELD The present invention relates to a band such as a watch band, bracelet, necklace, chain and belt.

2. Description of the Related Art As shown in FIG. 19, a conventional raft-shaped band has a plurality of narrow middle pieces 1 arranged in parallel with each other and having a constant interval so that both ends thereof are superposed. The center piece main body 4 has a plurality of rows knitted by inserting pins 3 into the holes 2 provided in the overlapping portions of both ends of 1, and the edge pieces 5 juxtaposed on both sides of the middle piece body 4 are provided. After inserting both ends of the pin 3 shown in FIG. 20 into the holes 6 provided at both ends, the U-shaped annular groove 7 formed at both ends of the pin 3 is arranged inside the hole 6 of the edge piece 5. As shown in FIG. 21, the back side of the edge piece 5 is struck by a press to form the crimping fixing portion 8.
The both ends of the pin 3 are fixed to the edge piece 5 by engaging the protrusions 9 projecting on the inner peripheral surface of the hole 6 at the positions corresponding to the crimping fixing portion 8 of the pin 3 with the annular grooves 7 of the both ends of the pin 3, respectively. Was.

Further, a band piece having a shape in which opposite corners of a rectangular parallelepiped block are cut out is formed with engaging holes on the inner side and engaging pins on the outer side, and the pieces are symmetrically and in series. A band coupling device combined and combined is disclosed in Japanese Patent Laid-Open No. 63-3119.
It is proposed as No. 05.

However, in the raft-shaped band described above, when the length of the band is adjusted, both ends of the pin 3 are fixed to the edge piece 5, respectively. Since it cannot be removed from the pin 3, it is necessary to give another piece or Nakadome a piece adjustment function. If this piece adjustment function is not available, the edge piece 5 can be forcibly removed from the pin 3 with pliers or the like. I have to take it off,
Moreover, the engagement between the annular groove 7 of the pin 3 and the protrusion 9 on the inner peripheral surface of the hole 6 of the edge piece 5 requires the piece edge 5 to be caulked and fixed, so that assembly of the band is troublesome. It was
Further, since it is necessary to form annular grooves on the outer peripheral surfaces of both ends of the pin, it takes time and labor to manufacture the pin, and the manufacturing cost of the pin is also high. Requires a U-shaped middle clasp piece in which two opposite band pieces are sandwiched. Without this clasp piece, the opposite band pieces move in the direction of separation and the band is disassembled. .

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by inserting one end of a pin connecting a piece main body into an insertion hole of the base of one piece of the piece main body and inserting the other end of the pin into the base of the other piece. Insert into the hole and rotate the other piece with respect to one piece to engage the engagement surfaces formed on the engaging parts of the protrusions of each other, and connect the one piece and the other piece with a pin Then, insert the other end of the pin, one end of which has been inserted into the insertion hole of the base of one of the pieces of the other piece main body, into the through holes of the projection of the one piece and the projection of the other piece, and separate the other end of the pin. Band is assembled by inserting it into the insertion hole of the base of the other piece of the piece body, and rotating the other piece of the other piece body with respect to the one piece. The engaging surfaces of the protrusions of the other piece engage with each other, and the resistance to twisting of the band of the piece main body is great, and no tools are used. Without, can the connecting engagement and frame body between one piece and the other piece at your fingertips, it is not necessary to fix by caulking with respect to the frame body pins, moreover,
If one piece is engaged in the opposite operation to the other piece, the piece main body and the other piece main body will be disengaged, and the length of the band can be easily adjusted. It is possible to expand the design variation by changing the, and it is not necessary to provide annular grooves at both ends of the pin, and the pin can be manufactured by simply cutting the round bar to a predetermined length, which reduces the manufacturing cost of the pin. , Therefore, to provide an inexpensive band.

In each of the above-mentioned embodiments, the pin is formed separately from each piece, but it is also possible to fix one end of the pin to one piece in advance, and to combine only the pieces when assembling, An elastic pin such as a spring rod may be attached later, and the base of the piece and the protrusion may be integrated or separate.

Furthermore, by changing the size of the piece bodies to be connected, the distance between the facing surfaces of the bases of one piece body does not necessarily have to be larger than the width of the protrusion of the piece body. The other piece may be rotated at an angle other than 90 °.

As described above, according to the band of the present invention, one end of the pin that connects the piece main body is inserted into the insertion hole provided in the base portion of one piece of the piece main body, and the other end of the pin is the other end. The two pieces are inserted into the insertion holes provided at the bases of the pieces, and the other piece is rotated with respect to one piece to engage the engaging surfaces formed on the protrusions so that the pieces cannot be separated from each other in the width direction. After engaging and connecting one piece and the other piece by inserting a pin into the engaging projection of one piece and the engaging projection of the other piece, the base of one piece of another piece body is inserted. Insert the other end of the pin, one end of which is inserted into the hole, into the through hole provided in the protrusion of one piece and the protrusion of the other piece, and use the other end of the pin as an insertion hole in the base of the other piece of the other piece body. Insert and rotate the other piece of this other piece body with respect to one piece to easily assemble the band And the engaging surfaces of the projections integrally formed on the base of one piece and the base of the other piece engage with each other, and at the same time, the tip of the projection of the piece of the piece body is placed between the base of another piece body. Since it is located facing, the resistance of the piece body to the twist of the band is large, and without using any tool, the engagement of one piece and the other piece and the connection of the piece body can be performed with only the fingertips, There is no need to separate one piece from the other without using a U-shaped piece, there is no need to crimp and fix the pins to the piece body, and one piece to the other piece. By simply performing the opposite operation to when engaged, the piece main body and another piece main body can be separated, the length of the band can be easily adjusted, and the shapes of the base and projection of the piece main body can be changed. By doing so, it is possible to expand design variations.

Also, because it is not necessary to provide annular grooves on both ends of the pin,
Pins can be manufactured simply by cutting the round bar to a specified length.
The cost of manufacturing the pins becomes low, and the pins can be mass-produced.

Both sides of the band can be used, and if the color, pattern, material, etc. of the surface are changed for each piece, a wider variety of bands can be created with only fingertips.
