There is a buckle consisting of a piece 48 and the other half of the buckle.

The conventional buckle described above has a structure in which the side plates 42 and 45 are arranged in series with each other and exposed on both sides of the upper plate 47, and has a good appearance. It has a simple structure that is attached to the proximal ends of 42 and 45, and the buckle thickness can be made relatively thin, and the width of the buckle can be set as desired, so it has been widely used in the past.

However, the above-mentioned conventional buckle has a difficulty in the hooking and unhooking operation. That is, in the latching operation, as shown in FIG.
8 on the shaft 43, then close the upper plate 47 in the direction of the arrow 49, pull together the first side plate 42 and the second side plate 45, and attach the hanging piece 48 to the shaft attachment part. To latch and unhook the 50, perform the reverse operation to the above.
Operation is unstable and requires care and skill.

This invention solves the above-mentioned difficulties of the conventional buckle, and the invention will be explained below based on the drawings showing one embodiment.

The buckle for a watch band of this invention includes a first side plate 2 and a first shaft 3 suspended between the first side plates.
and a second shaft 4 suspended between the first side plates 2 and provided parallel to the first shaft 3; and a hanging piece 5 that is hooked onto and removed from the first shaft 3. , an upper plate 6 formed by extending the hooking piece, a second side plate 7 formed on both sides of the base end of the upper plate 6, and a tip formed on the outside of the second side plate. a third side plate 9 which is arranged in series with the first side plate 2 so as to face the tip of the first side plate 2; and a third shaft 12 suspended between the third side plate 9; The other half of the buckle includes a hook 10 which is rotatably mounted and placed below the upper plate 6, and whose tip portion is hooked onto and removed from the second shaft 4.

Next, an example will be described, and the drawings of the example show an example in which a buckle is attached to a band body using a joint member.

In the embodiment, a joint member for attaching each band body 1, 8 to the proximal ends of the first side plate 2 and the third side plate 9 is attached to the tip of the first band body 1 and the second band body 8. be. 17 is the top plate of the joint member. 1
8 is formed at the tip of the top plate 17, and the third shaft 12
and a winding section attached to the fourth shaft 11, respectively. 19
is a stepped groove formed in a part of the winding portion 18. 20
are fourth side plates formed on both sides of the top plate 17. 2
1 is a hole formed in the fourth side plate 20. Note that the fourth shaft 11 described above is suspended from the base ends of the first side plates 2.

Reference numeral 22 denotes a rotation stopper plate of the joint member, in which both protrusions 23 formed on both sides of the base end are attached to the hole 21, and a first engaging piece 24 with the base end erected is attached to the first engaging piece 24 formed on the band bodies 1 and 8. The joint member is engaged with the groove 25.
They are attached to the tips of band bodies 1 and 8, respectively.

13 is a bottom plate formed between the first side plates 2; Reference numeral 14 denotes bearing pieces formed on both sides of the base end of the hook 10 and rotatably attached to the third shaft 12. 15 is a bearing hole through which the shaft 12 passes.

26 is a second engagement piece in which a part of the base end of the hook 10 is raised. Reference numeral 27 indicates a third engagement piece that stands up at one end of the bottom plate 13, and reference numerals 26 and 27 each indicate a step groove 19.
This prevents the hook 10 and the bottom plate 13 from rotating in the directions of arrows 28 and 29, respectively, when the buckle is engaged with or removed from the buckle.

The hanging member shown in FIG. 5 has both sides of the upper plate 6 bent downward to form second side plates 7, and further includes:
Since the third side plates 9 are formed by folding up the second side plates 7 outward, the upper plate 6 and the third side plates 9 can be easily formed integrally. Since both side plates 9 can be easily exposed, the first side plate 2 and the third side plate 9 can be placed in series with each other and exposed on both sides of the upper plate 6, as shown in Fig. 2A. can be made good.

Another embodiment of the hanging member shown in FIG. 7 is one in which a decorative top plate 16 is superimposed on the top plate 6 by welding or the like.

Next, the action will be explained.

To lock the buckle, first, as shown by the two-dot chain line in Figure 2, with the top plate 6 open, hook 10 is hooked to the second shaft 4, and the buckle is attached to one half of the buckle. The other half is fixed, and then, in the fixed state, the upper plate 6 is moved to the state shown by the solid line, and the latching piece 5 is latched to the first shaft 3 to perform the latching operation. , stable operation, easy and reliable operation. In addition, the removal operation
Since the above-mentioned latching operation is the reverse, no skill is required to latching or unhooking the buckle, and the operation is stable.
It can be easily and reliably hung.

As described above, the upper plate 6 and the third side plates 9 are integrally formed, and the third shaft 12
Since the hook 10 is rotatably mounted, it can be opened and closed as a unit, as shown in Figure 2, regardless of the rotation of the hook 10. When the first side plate 2
Therefore, the gap 30 between the tips of the first and third side plates 2 and 9, which are opposed to each other, is equal to the length 31 for hooking and unhooking the hook 10 to the second shaft 4. Regardless of the situation, you can reduce the number of bags, and you don't have to worry about them getting caught on cuffs, etc.
Good appearance as well. Furthermore, even if the above-mentioned gap 30 is reduced, the hook 10 hanging dimension 31 is
As illustrated in FIG. 2B, the hook can be made large enough to be latched, and the hook and the hooking member can be latched securely.

Furthermore, when forming both side plates and the upper plate 6 integrally, it is generally easy to think of forming large second side plates 7 on both sides of the upper plate 6,
A hook 10 and a second band body 8 are attached to the second side plates 7.
The other half of the buckle is completed by attaching the second half of the buckle.As explained above, this invention is based on the fact that the third side plates 9 are further formed on the outside of the second side plates 7. The third side plates 9 can be easily arranged on both outer sides of the upper plate 6. Therefore, when the other half of the buckle is hooked to one half of the buckle, the third side plates 9 can be easily placed on both outer sides of the upper plate 6. The first side plates 2, 2 provided on one half of the buckle and the third side plates 9, 9 provided on the other half of the buckle can be arranged in series with their tips facing each other. This allows for good balance between the halves.

Therefore, the effect of this invention is as mentioned above.
By configuring one half of the buckle as the other half of the buckle with the hook 10 rotatably attached to the top plate 6, the difficulties of conventional buckles can be solved and the hanging and unhooking operations can be stabilized. , it is possible to obtain a buckle that can be easily and reliably hooked and unhooked.

Furthermore, in addition to the improvement of the conventional buckle described above, the other half of the buckle of this invention has the above-mentioned effect by configuring a hanging member in which the upper plate 6 is integrally formed with the third side panels 9. In addition, the gap 30 between the side plates 2, 2 and 9, 9 can be reduced,
There is no need to worry about the cuffs being caught, and furthermore, the length 31 of the hook 10 for hooking and unhooking can be made large enough for hooking, so that hooking can be ensured. In addition, by forming the third side plates 9, 9, the buckle can be well balanced as described above, and the buckle for the watch band is good both in terms of appearance and functionality. This is something that can be provided.
