Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a triple-fold metal fitting for a watch band.

<Problems that this invention attempts to solve> This type of three-fold metal fitting was developed in 1986-8612.
However, since the opening/closing plate is latched to the inner side surface of the frame plate when folded, there is a problem that as the opening/closing plate is repeatedly opened and closed, each other wears out and becomes loose, weakening the latching effect. . The present invention attempts to solve such problems.

<Structure of the invention> The present invention is provided with a latching protrusion on the center of the frame-like plate, and a latching groove for engaging and detaching the protrusion at the corresponding ends of both opening/closing plates, and a movable groove following the latching/disengaging groove. The reason lies in the fact that a double-fold type three-fold metal fitting for a watch band is constructed by providing an extremely long split groove.

<Example> Examples will be described below with reference to the drawings.

A flat plate 2 is provided across the center of the frame-shaped plate 1, and an enlarged part 3a is provided on the upper side surface of the flat plate 2.
A protrusion 3 having a horizontally oblong rectangular shape in plan view and having a constricted latching surface 3b at the bottom is implanted. The opening/closing plates 5a and 5b, which are connected to both ends of the frame-like plate 1 by pins 4, are cut out at the center of the end to provide hooking grooves 6a and 6b for hooking onto and removing from the protrusion 3, and the inner ends of the hooking grooves 6a and 6b are provided with hooking grooves 6a and 6b. The grooves 7a and 7b are connected to the grooves 7a and 7b and are as long as possible in the axial direction. 8a, 8b
9 is a circular wall for groove stop, and 9a and 9b are pin cylinders for connecting to a watch band.

In the watch band 10a, pin tubes 9a and 9b are inserted between mounting tubes 13a and 13b which are brazed to the groove 12 at the back end of the end piece 11, and the pin tubes 9a and 9b are connected with the pin 14.
Further, the plate-shaped band 10b made of leather, urethane, etc. is connected together with the band using a mounting bracket 15 shown in FIG.

<Effects of the invention> Since the invention is constructed as described above, the dividing grooves 7a and 7b provided in both opening and closing plates 5a and 5b are connected to the hooking groove 6.
Since a and 6b are imparted with spring properties that allow them to open and return laterally, the effect that the hooking action does not deteriorate even if the hooks are repeatedly hooked and unhooked from the protrusion 3 is produced.
