Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band-shaped accessory such as a wrist watch band and a bracelet.

[0002]

2. Description of the Related Art In a watch band in which a large number of metal pieces are connected in a band shape by pins, various kinds of bands equipped with a length adjusting device which can adjust the length according to the thickness of an arm are practically used. Has been done.

FIG. 6 is a perspective view showing an example of such a band. In this band, several pieces 1 and 2 at the end of the band are connected by a hairpin-shaped connecting pin 3. In order to adjust the length of the band, the end of the hairpin-shaped connecting pin 3 which is divided into lids is pushed in the lateral direction of the band by the push rod 4, and the curved end of the connecting pin 3 is placed on the opposite side of the bridge 2. Extrude into. Grasp the curved end of the connecting pin 3 with the tweezers 5 and pull out the pin. In this way, the engagement between the pieces 1 and 2 is released. If the piece 2 is removed from the band, the length of the band is shortened by the length of the piece 2. Further, if another piece is inserted between the pieces 1 and 2 and connected by the connecting pin 3, the length of the band is increased by the length of the added piece.

[0004]

In such a band, the push rod 4 and the tweezers 5 must be used, and a skilled work is required for the operation, and it is not possible to adjust the length of the band. , It will be troublesome and difficult for the user. Also, not all pieces are connected by hairpin-shaped pins, so there is a limit to the adjustment length,
It cannot be adjusted significantly. It is an object of the present invention to provide a band-shaped accessory that allows a user to easily adjust the length of the band-shaped jewelry such as a watch band, a bracelet, and a necklace without using a special tool. .

[0005]

According to a first aspect of the present invention, there is provided a belt-shaped accessory which is inserted into an opening of an expanding portion which extends outward and a pair of piece pieces which are joined to each other and which is bent inward. ,
It has a unit piece consisting of a connecting pin penetrating through the connecting holes of both joints of the adjacent pieces and detachably engaged with a hole formed in the other expansion part, and a coupling ring for press-contacting the joints of both piece pieces. It is characterized by In the belt-shaped accessory according to claim 2, the hole formed in the expansion portion is a blind hole. In the strip-shaped accessory according to claim 3, each piece is bent in a crank shape. In the belt-shaped accessory according to the fourth aspect, the decorative member may be arranged on at least one side on both sides of the joint.

[0006]

1 is a plan view showing an embodiment in which the present invention is applied to a wristwatch band, FIG. 2 is a perspective view showing a part of a piece, and FIG. 3 is an exploded plan view showing a unit piece. FIG. 4 is a cutaway plan view of a unit piece. The unit piece 10 includes a pair of piece pieces 11 and 12 bent symmetrically in a crank shape as shown in FIG.
And a coupling ring 13. Each piece has an expanded portion 11a, 12a that extends outward and a joint portion 11 that bends inward.
b, 12b, one of the expanded portions 12a is provided with a blind hole 12c as shown in FIG. 4, and the base of the connecting pin 14 is press-fitted and fixed. A blind hole 11c into which the tip of the pin 14 is detachably fitted is formed in the expanded portion 11a. Furthermore, the joints 11b and 12b
Has a shape that allows the extension portions 11a and 12a of adjacent pieces to be engaged with each other, and when they are engaged with each other, connection holes 16 are formed so that the connection pins 14 are rotatably engaged.

As shown in FIG. 4, the coupling ring 13 is formed with a hole 13a for pressing the joint portions 11b and 12b against each other. When joined in this way, the hole 16 is the ring 13
It is exposed to the outside, and the expanded portion of the adjacent piece can be engaged with that portion. In order to connect the piece having the above structure to the timepiece case 15 of FIG. 1, the timepiece case has a pair of connection protrusions 17 having the same shape as the joining portions 11b and 12b of the pieces.
Is provided.

In order to connect the pieces to each other, as shown in FIG. 4, the piece pieces 11 and 12 of one piece to be connected are aligned with each other and are joined together by a coupling ring 13. The other connecting piece is in a disassembled state as shown in FIG. 3, the connecting pin 14 of one piece piece 12 of the piece piece is inserted into the hole 16 of the adjacent joint part, and the other piece piece 11 is further connected. The hole 11c is engaged with the tip of the pin 14. Next, the joining ring 13 is fitted to the joined portion of the joining pieces to join the two pieces. Thereafter, the pieces are sequentially connected to form a band. A piece is first connected to the watch case 15, or a completed band is connected by a spring rod. Further, in the band using the clasp 18, the end piece is connected by the spring rod 19.

To adjust the length of the band, the spring rod 19 of the clasp 18 is removed. When shortening the length, the piece can be easily removed by pulling out the connecting ring 13 of the end piece. In order to make it longer, another piece may be connected as described above.

Although the connecting pin 14 is press-fitted and fixed in the blind hole 12c in the above embodiment, the connecting pin 14 is inserted in the blind hole 12c.
It goes without saying that it may be detachable.

It is also possible to provide a pair of connecting protrusions 15 having the same shape as the extension portions 11a and 12a of the piece, and connect the joint portions 11b and 12b of the piece to the connecting protrusions. In the above-described embodiment, the pair of joints is formed as one pattern as shown in FIG. 1, but the present invention is not limited to this, and as shown in FIG. You may arrange one by one and try to expand the design variation. Further, two or more of the decorative members 20 may be arranged on both sides of the joint, or at least one may be arranged between the joint 11b and the joint 12b. Decorative members 20 on both sides of the joint
When arranging, the size of the expanded portion that expands outward is determined in advance so that the joint portion and the decorative member 20 can be inserted.

The fixing of the decorative member 20 of the pair of pieces is as follows.
A through hole is provided in the decorative member 20, and the connecting pin 1 is provided in this through hole.
4 or insert the connecting pin 1 into this through hole.
4 and inserting one end into the coupling ring.

[0012]

The band-shaped accessory according to the present invention can easily adjust the length of the band without requiring any special tool or knowledge. Therefore, it can be easily adjusted by the user. Furthermore, since all can be disassembled, various pieces, connecting rings,
It is also possible to prepare ornamental members and combine them appropriately to make a variety of accessories according to the taste of the user.

Further, in the case of a band-shaped accessory to which a precious stone such as diamond or ruby is attached, unlike the conventional case, the piece piece, the coupling ring with the precious stone, and the decorative member with the precious stone are completed and then assembled to form a belt-shaped accessory. Therefore, processing restrictions such as attaching processing of precious stones and assembling processing of band-shaped accessories are extremely reduced, and furthermore, scratches and the like due to the processing are eliminated, and it is possible to provide a band-shaped accessory with a high-class feeling.
