Description

[Detailed description of the invention] It is.

The clasp for the "Ankun" band consists of a locking metal fitting that can be fixed at any position on one band, and a latch attached to the end of the other band. Some have a structure in which the band is connected by locking onto a stopper. This type of clasp has the advantage that the length of the band can be adjusted arbitrarily and the connection operation is easy. , as both bands separate completely, the watch may fall and be damaged.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a clasp structure that can ensure engagement of the latch with the locking metal fitting and prevent the watch from falling. According to this purpose, in the present invention:
After the pusher is rotatably attached to the locking bracket and the latch is locked to the lock, the pusher is rotated to position it above the latch, thereby allowing the latch to move away from the locking bracket. The feature is that it is designed to prevent withdrawal.

Embodiments of the present invention will be described below with reference to the drawings.

This clasp consists of a locking fitting 1, a latch fitting 2, and a pressing fitting 6. The locking fitting 1 consists of a frame 4, a bottom plate 5, and a push plate 6, and the latch fitting 2 consists of a frame 7, a temporary latch 8, and a latch 1.
Consists of 0.

As shown in FIG. 2, the frame 4 has opposing side plates 11
and three shaft rods 16 installed between the bottom plate 12 and both side plates 11.
．． 14 and 15, and on the upper surface of the bottom plate 12, locking convex portions 16 that engage with locking recesses 21° provided on the back surface of the band 20 are protruded at four locations. The bottom plate 5 is the third
As shown in the figure, it is rotatably attached to the shaft 14 of the main frame 4 at the ear 17, and has a bent portion 18 for facilitating insertion of the band 20 and an elastic portion that abuts the lower part of the shaft 15. 22 and a bottom portion 24 that suppresses the top surface of the band 20.
The bottom part 24 is slightly curved in the direction of the shaft rods 16, 14, and 15.

As shown in FIG. 4, the pressing plate 6 is rotatably attached to the shaft rod 14 of the frame 4 at a winding part 25, and a pressing protrusion 26 is formed in a part of the winding part 25. The rolled ends 27, 28 are slightly open so that a screwdriver, bottle set, etc. can be inserted.

As shown in FIG. 5, the frame 7 of the latch 2 is fixed to the other band 600 by soldering or by spot welding, and as shown in FIG. A protruding claw 66 is provided on a part of the ear portion 61. As shown in FIG. 7, the temporary latch 8 consists of a hook portion 64 hooked onto the shaft 15 of the frame 4 and a winding portion 65 pivotally attached to the shaft 62 of the frame 7. A protrusion 66 is provided on the outside to abut against a protrusion claw 66 of the frame 7 to prevent the hook portion 64 from rotating upward, and a notch 67 is provided on the inside. As shown in FIG.
It has a winding part 40 that is pivotally attached to the shaft 62 and a hole 41, and on both sides of the winding part 40 there are steps that abut the notches 67 of the temporary latch 8 and rotate the temporary latch 8 upward. A section 42 is provided.

To assemble the temporary latch 8 and the latch 10 to the frame 7, combine the winding part 65 of the temporary latch 8 and the winding part 40 of the latch 10 so that the notch part 67 and the step part 42 engage with each other, and then 7
It is pivotally connected to a shaft rod 62 attached to an ear part 61 of.

The pushing metal fitting 6 is pivotally connected to the shaft 16 of the frame 4 at both side wall portions 44, and is formed in a 5&C shape so that it can be stacked over the latch 10 as shown in FIG.
A protrusion 45 that engages with the hole 41 of the latch 10 is provided at the tip.

Next, we will explain how to use this device. First, Nokundo 2
0 between the bottom plate 12 and bottom plate 5 of the frame 4, rotate the push plate 6 at an appropriate position according to the thickness of the arm to make the push protrusion 26 stand up, and press the The bottom plate 5 and the bottom plate 1
2 and fix the frame 4 to the band.

Next, place your finger on the tip of the latch 10 and pull it upward.

At this time, the hook part 64 of the temporary latch 8 is pulled up together with the latch by the stepped part 42, but the protruding part 6 of the temporary latch 8
6 comes into contact with the protruding claw 66 of the frame 7, and the hook portion 64
The second locking shaft rods 1□ and 5 of the frame 4 are fastened to a position where it can be easily hung. In this state, the hook portion 64 is hooked onto the second locking shaft 15, and then the latch 10 is pushed down to bring the spray portion 68 into engagement with the first locking shaft 13 in one spray. Subsequently, the restrainer 6 is rotated to overlap the latch 10, and the protrusion 45 is engaged with the hole 41 of the latch so that it is in close contact with the latch. If you want to remove it, just do the reverse of the above operation.

In the above embodiment, the protrusion 45 of the pushing metal fitting 6 and the hole 41 with which the protrusion engages are not necessarily necessary, and the wall portion 4
4 and the frame 40 and the plate 11 may be fitted together to fix the press fitting 6 to the frame 4.As is clear from the above, according to the present invention, the latch
The push metal fittings installed so that the opening direction is opposite overlaps the latch and holds it down, so the latch will not open and the watch will not fall off due to the band coming off. Therefore, it is possible to provide a safe and secure clasp structure.
