Description

[Detailed description of the invention] This invention relates to a watch band stopper that connects leather bands etc. that have holes.

Conventionally, fasteners such as leather bands are connected by engaging a pin with a buckle (or buckle) into a hole formed in the leather band. It is popular as a fastener and is relatively easy to use.

For example, when using the band, fit the tip of the band into the buckle and pull it back to adjust the length of the band, then fit the hole on the stick that comes next, and fill the remaining tip of the band with dirt. The operation of mating was performed.

However, due to these operations, the surface of the band is easily rubbed and deformed when it is fitted with the buckle, and it is inevitable that the band will be deformed, and even if the band is made of high-quality leather, it will be damaged by the buckle. In addition, the connection between the buckle and the band is made by fitting the attached rod and the attached hole, so the fixation of the band in the length direction is unstable, and the excess parts of the band and road grass protrude, resulting in an unsightly appearance. There was also the problem of damage.

This invention was made against this background, and aims to improve the above-mentioned problems by new means, and to provide a fastener that is easy to use and ensures reliable connection.

This invention will be explained below based on embodiments shown in the drawings.

The bands indicated by numerals 1 and 2 in the figure are known bands, in which one band 1 is provided with a plurality of holes 3, and the other band 2 is provided with engagement holes 4 by folding back the end. At the same time, a notch 5 is formed that spans the center of the length of the engagement hole 4.

A movable fitting 10 made of metal (or synthetic resin, etc.), which is one of the fasteners of this invention, is attached to the one band 1.

The movable fitting 10 includes a bottom plate 11 that contacts the back surface of the band 1, and a bottom plate 11 that is formed integrally with the bottom plate 11 to limit the swinging of one band 1 in the width direction and to move the band 1 along the length direction. movable side plates 12.12, pins 13.14 attached between the side plates 12.12 and spaced apart from each other in the length direction of the band 1 and also with respect to the bottom plate 11; A locking piece 15 is rotatably attached to the band 13 and is inserted into the hole 3 of one of the bands 1 to suppress movement (that is, for positioning), and is integrally formed with the locking piece 15. and other pin 1
A stop piece 16 is provided, which contacts the locking piece 4 and limits the upward rotation of the locking piece 15 in FIG. 3.

The locking piece 15 is normally fitted into the hole 3 supported between the bottom plate 11 and the pin 14.

Further, the other hook 20 of the stopper of this invention is rotatably attached to the engagement hole 4 and the notch 5 of the other band 2.

The metal fitting 20 is inserted into the engagement hole 4 of the other band 2 and fixed, and a mounting shaft 21 is inserted into the notch 5 of the band 2 and supported rotatably by the mounting shaft 21, and the metal fitting 20 is Hook piece 22 that can be hooked onto the pin 13 of the metal fitting 10
Similarly to this hook piece 22, there is a movable metal fitting 10 supported by the mounting shaft 21, a top plate 23 covering the front side of the hook piece 22, and a movable metal fitting 1'0 formed by folding back the tip of this top plate 23.
A plurality of clamping members 4a, 24b, 2 are arranged in a staggered manner as shown in FIG.
4 d is formed.

Hereinafter, the operation of the fastener configured in this way will be explained.

First, attach a watch (not shown) to both bands 1 and 2, and attach the metal fitting 20 to the other band 2 on the mounting shaft 2.
1 so as to be rotatable (usually in this state), and the locking piece 15 of the movable fitting 10 is elastically deformed against the supporting force of the stopper piece 16 to move upward in FIG. Raise it up, then remove the bottom plate 11 and pin 13 of the movable fitting 10,
14 to adjust the length, rotate the locking piece 15 counterclockwise in FIG. 3 and insert it into the hole 3 of one band 2, Locking piece 15
Push with strong force to insert and fix the stop pieces 16 under the pin 14.

By this fixation, one band 2 and the movable metal fitting 10 are integrated.

Next, the hook piece 22 of the metal fitting 20 is hooked onto the pin 13 of the movable metal fitting 10, and the top plate 23 is folded down so as to cover the movable metal fitting 10, and each clamping portion 24a, 24b of the fixed piece 24 is attached.
, 24c are fitted onto the pin 14 to form the state shown in FIGS. 1 and 2.

When the bands 1 and 2 are connected by the stopper in this way, even if tension is applied to the bands 1 and 2, the hole 3 in one band 1 and the locking piece 15 of the movable fitting 10 will not connect. Only the force that moves the band 1 in the length direction acts between them, and no force that bends the band 1, rubs the band 1, or distorts the hole 3 is applied, and the band 1 moves. The metal fitting 10 and the hook remain the same even when the metal fitting 20 is repeatedly attached and detached (that is, the operation of removing the watch from the wrist and attaching it to the wrist).

In addition, when removing the hook 20, the above-described operation is reversed, that is, the top plate 23 is raised to release the engagement between the pin 14 and the fixing piece 24, and then the hook piece 22 is removed from the pin 13.

This stopper is connected to the movable metal fitting 10 and one band piece 1.
Once the position of the metal fitting 20 is determined,
It can be integrated by simply fitting it into 4, and there is no need to adjust the length of the band.

As is clear from the above explanation, this invention is based on a fastener that connects bands with holes, and a movable fitting that can be moved along one band and a pin that locks the other band. A locking piece that is inserted into the hole that is attached to the metal fitting is provided, and the hook attached to the other band is provided with a top plate that covers the movable fitting, a fixing piece that folds back this top plate and fits the pin. Since it is designed to connect both bands by providing a effective.
