Description

[Detailed description of the invention] [Technical field of invention] TECHNICAL FIELD This invention relates to a stop for a watch band.

[Prior Art] Conventionally, there are fasteners used for wristwatch bands as shown in FIGS. 13 and 14. This type of stopper 1 is made by bending a metal plate made of stainless steel or the like into a substantially U-shape, and a restraining plate 2 is arranged on the bottom la side so as to be movable up and down. One band 3a of a pair of bands attached to both sides of the watch body is movably inserted between them, and two locking pins 4.5 are provided between both sides of the stopper 1 above the band 3a.
However, the bridge has been passed. As shown in FIG. 11, this locking pin 4.5 has hooks 6a and 6b of a metal locking member 6 provided at one end of the other band 3b that are releasably engaged with each other. There is a lock lever on one (left side in the figure) of the locking pin 4 that fixes the stopper 1 to the band 3a.
7 is rotatably attached. This lock lever 7
is made by bending a metal plate in two, and the center of this bent part is cut out, and is attached to both ends of the locking pin 4, and the bent part on both sides has a rotation of the lock lever 7. A projection 7a is formed to elastically restrain the restraining plate 2 as it moves.

Therefore, when connecting the pair of bands 3a and 3b, first, the stopper 1 is fixed at a predetermined position on the band 3a.

In this case, the lock lever 7 is rotated upward as shown in FIG.
When the band 3a is released from the holding plate 2, the band 3a moves between the holding plate 2 and the bottom part 1a of the stopper 1, so that the stopper l is placed at a predetermined position on the band 3a. In this condition.

When the lock lever 7 is rotated downward, as shown in FIG. 13, the protrusion 7a presses down on the holding plate 2, and the band 3a is held between the holding plate 2 and the bottom part 1a of the stop l. , the stopper 1 is fixed at a predetermined position on the band 3a, and the tip of the lock lever 7 abuts on the restraining plate 2. After this, each hook 6a of the locking member 6 provided at one end of the band 3b,
The pair of bands 3a and 3b can be connected by locking each of the bands 6b to each of the locking pins 4.5 of A1. In addition, when canceling the connection of bands 3a and 3b,
It is only necessary to pull up the locking member 6 provided at one end of the band 3a to stop each hook 6a, 6b and separate it from each Al locking pin 4.5.

[Problems with the prior art] However, in the watch band stopper 1 as described above, once it is fixed to the band 3a, the lock lever 7
Since the tip of the stopper plate 2 is in close contact with the upper surface of the retainer plate 2, it is not easy to pry it open and change the fixing position of the stopper l. Since it is necessary to pry the holding plate 2 with more force than the holding plate 7a is holding down, there is a risk that the nails may be peeled off if the holding plate 7a is used by hand. Therefore, a tool such as a screwdriver is required, and there is an inconvenience that the fixing position of the stopper 1 cannot be freely adjusted anytime and anywhere.

[) Purpose of Ame] This invention was made in consideration of the above circumstances, and its purpose is to enable the user to freely adjust the mounting position by hand anytime and anywhere without using any tools such as a screwdriver.
