Description

[Detailed description of the invention] <Industrial field of application> This invention relates to the structure of the coupling part of a watch band.

<Problems to be solved by this invention> A watch band engagement part in which one end of the watch band is inserted into the intermediate opening of the end piece, and the inserted end is connected with a spring bar within the end piece. The watch band inserted into the middle opening of the end piece rotated based on the spring bar and frequently hit the upper edge of the middle opening, causing scratches and the plating peeling off. The present invention attempts to solve such problems.

<Structure of the invention> The present invention provides a watch band in which an end of the band is inserted into an intermediate opening of an end piece, and the inserted portion is connected with a spring bar within the end piece. A stopper step surface is provided on the middle of the mouth edge and slightly protrudes in the direction of the relative mouth edge, and both sides of the insertion end of the band are stopped on the stopper step surface. It's in the structure of the watch band's mating part.

<Example> Examples will be described below based on the drawings.

Figures 1 to 3 show a first embodiment, which has an inverted U-shape with its front surface open and an oblong intermediate opening 2 in the middle of the base side, and holding pieces bent into a cylindrical shape on both inner surfaces thereof. 4a, 4b, an overhanging plate part is provided in the upper half of both sides rims 2a, 2b of the intermediate opening 2, and extends slightly toward the opposite rims 2a, 2b. Retaining step surfaces 6a and 6b are formed on the flat end surfaces of the portions, and the receptacle step surfaces 6
Both ends of the insertion portion 1a of the band 1 to be inserted into the intermediate opening 2 are received at the ends a and 6b.

The end of the insertion part 1a of the band 1 is inserted into the end piece 3 by a spring rod 5 held by the holding pieces 4a and 4b, and is connected to the end piece 3. The spring bar 5 is fitted between the legs 9a and 9b, and both ends of the spring bar 5 are fitted from the inside into holes provided in the inner halves of the mounting legs 9a and 9b, so that the spring bar 5 is integrally attached to the watch case 8.

Although the insertion part 1a of the band 1 is rotatable based on the spring rod 5, by having both ends thereof rested on the receptacle step surfaces 6a and 6b, it can be used before and after wearing. Even if the insertion portion 1a repeatedly rotates based on the spring rod 5, the upper surface of the insertion portion 1a will no longer collide with the upper lip 7 of the intermediate opening 2, and the collision will not occur. This eliminates damage to the upper surface of the insertion portion 1a and peeling off of the plating.

FIG. 4 shows an example in which the step surface of the stopper is formed by inclined surfaces 6c and 6d between the upper opening rim 7, and FIG. An example is shown in which a curved edge 6e is formed between the edge 7 and the edge 7, and the other configurations are the same as in the first embodiment.

<Effects of the invention> As described above, the present invention provides a stopper step surface extending toward the opposite opening on the middle of both side edges of the intermediate opening provided in the end piece. Since both ends of the insertion part inside the opening are held on the stopper step surfaces, the upper surface of the insertion part may be damaged or the plating may peel off if it hits the upper lip of the intermediate opening due to rotation. This has the effect of eliminating the problem.
