Description

[Detailed description of the invention] This invention is a middle clasp for a watch band in which an inner cover is attached to the band in addition to an outer cover, and a window hole is provided in the middle of the outer cover. The inner cover is formed so that it fits flush into the window hole, so that double hooking can be confirmed from the outside, and because the inner cover and outer cover are hooked on the same surface, a middle clasp is used. The reason is that it can be formed thinly.

To explain the present invention in detail with reference to the accompanying drawings, one half of the metal fitting 16 constituting the middle clasp has a bottom plate 11 and folded walls 12, 12' on both sides thereof, and a center portion between the folded walls 12, 12'. A rotation restraint piece 13 is installed across the board.

The rotation prevention piece 13 is a shaft 2 installed between the vertical walls 12 and 12'.
It has an operating piece 27 formed by an extension of the bottom part of the acute triangular push member 13' wrapped around the
The middle part of 7 is cut into a short length to form a hook part 28.

A push plate 29 is provided below the push member 13', and when the operating piece 27 is rotated in the direction of the arrow in FIG.
3' turns sideways and releases the push from the push plate 29, so the band 23 can freely pass between the push plate 29 and the bottom plate 11. When the operating piece 27 is pushed down and rotated in the direction opposite to the arrow, the second
As shown in the figure, the acute angle portion of the pushing member 13' pushes the pushing plate 29, and the band 23 is clamped between the pushing plate 29 and the bottom plate 11.

Incidentally, protrusions 30 are provided on both sides of the bottom plate 11, and grooves 31 are provided on both sides of the back surface of the band 23 so as to mesh with each other to ensure that the straps are not clamped.

A first shaft rod 14 and a second shaft rod 15 are provided on both sides of the folded walls 12, 12' sandwiching the rotation prevention piece 13, thereby forming one half of the metal fitting 16.

The other metal fitting 22 constituting the middle clasp fitting includes a cylindrical portion 32 for a bearing extending from the lower surface of the end of the band 23', and the cylindrical portion 3.
A plate-shaped hook member 17 that extends forward and has a mounting shaft 33 that is inserted into the mounting shaft 2 and side plates 34 that are fitted to both ends of the mounting shaft 33.
, the outer cover 21 wrapped around the mounting shaft 33, and the outer cover 2
1 has a window hole 24 in the middle, and an inner lid 19 that fits into the window hole 24 in contact with the window hole 24 is wound and attached to a mounting shaft 33.

The hook member 17 is hooked on and removed from the first shaft 14 of the one-half metal fitting 16, and the umbrella-shaped hooking piece 18 hanging down from the inner surface of the inner lid 19 is attached to the middle of the rotation prevention piece 13 that has been rotated to the holding side. The claw piece 20 that is hooked and detached between the hook member 17 hooked on the hooking part 28 and the first shaft rod 14, and that is vertically provided on the inner surface of the outer cover 21, is connected to the second shaft rod 1.
It is designed to be eliminated at 5.

In this middle clasp fitting of the present invention, a window hole 24 is provided in the outer cover 21 of the inner clasp 22, and the inner cover 19 is provided with a window hole 24.
4, so that it is possible to check the attachment of the umbrella-shaped hooking piece 18, which was previously hidden inside the outer cover and could not be confirmed externally, through the window hole 24. Therefore, it can be used with peace of mind.

Furthermore, unlike the case in which the inner lid 19 is attached to the inside of the outer cover 21, it can be attached on the same plane as the outer cover 21, so that the inner clasp can be made thinner accordingly.

In this way, the present invention has the effect of making the double-hook type watch band even more useful.
