Description

[Detailed explanation of the idea] This invention relates to buckles for watch bands and the like.

Conventionally, various types of buckles of this type have been developed and put into practical use.

By the way, since watch bands and the like to which this type of buckle can be attached have high value as accessories, there is a strong tendency for the general public to demand particularly excellent decorative items, that is, items with a high design quality.

Therefore, it is naturally desired that the buckle attached to the band etc. does not impair the design of the band itself.

On the other hand, it is also necessary that the function as a buckle be excellent, that is, the band should be easy to attach and detach from the buckle, and that these operations can be performed reliably.

This idea was made with the above points in mind.
The purpose is to provide a buckle for a watch band or the like that is easy to attach and detach the band from the buckle, works reliably, and has an excellent design.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 indicates a buckle of this invention, and this buckle 1 has a buckle body 2 whose cross section is formed into a rectangular shape by bending both edges.
It mainly consists of a presser metal fitting 5 whose plate end is rotatably connected to a connecting part 3 provided on one edge 2a (bending piece) of the main body 2 via a hinge pin 4.

A protrusion 6 is formed on the other edge 2b (bent piece) of the buckle main body 2 and extends along the edge.

On the other hand, at the other end (free end) in the longitudinal direction of the presser metal fitting 5,
An engagement member 7 having an engagement recess 7a and a claw 7b that engages with the protrusion 6 is rotatably supported by a pivot pin 8.

This engaging member 7 is integrally provided with a lever 9 for rotating the engaging member 7 to release the engagement state with the protrusion 6.

Furthermore, reference numeral 10 denotes a stop pin having a head 10a protruding from the inner center of the bottom plate 2c of the buckle main body 2;
0 is a bent piece 10a10b formed at both ends of the bottom plate 2c.
It is inserted into a fastening hole 12 of a band piece 11 made of, for example, leather, which is inserted between the holes to fasten the band piece 11.

Further, reference numeral 13 indicates a shaft pin 1 whose one end is attached to the watch body (not shown) and whose other end is installed between the bent pieces 2a and 2b.
This is a band piece made of leather or the like that is attached to the buckle main body 2 via 4.

Incidentally, the material for forming the buckle 1 is preferably a corrosion-resistant metal such as stainless steel, but it may also be made of a synthetic resin such as plastic.

The operation of a buckle such as a watch band configured as described above will be explained. First, in order to position the band piece 11 with respect to the buckle 1,
As shown in FIG. 1, the presser metal fitting 5 is maintained in an open state, the locking pin 10 of the buckle main body 2 is inserted into the predetermined locking hole 12 of the band piece 11, and then the presser metal fitting 5 is The engaging member 7 of the presser fitting 5 is rotated in the direction indicated by A.
This is performed by engaging the protrusion 6 of the main body 2 with the protrusion 6 of the main body 2.

By the way, FIG. 2 shows the state of engagement between the engagement member 7 and the protrusion 6 at this time. To explain in more detail how this state is reached, first, the engagement member 7 is normally Although the state is approximately as shown in FIG. 3, when the presser metal fitting 5 is rotated toward the main body 2, the protrusion 6 comes into contact with the vicinity of the engagement recess 7a of the engagement member 7, and the engagement member 7 is pushed into the pin 8. Rotate clockwise in the diagram around .

Here, when the presser metal fitting 5 is further rotated toward the main body 2 side, the bent piece 2b having the protrusion 6 is slightly elastically deformed inward (toward the stopper 10 side), whereby the protrusion 6 is engaged. It engages with the engagement recess 7a of the member 7.

As a result, the presser metal fitting 5 is locked to the buckle main body 2.

In addition, in order to release the engagement state between the engagement member 7 and the protrusion 6, if the lever 9 is pushed upward, that is, rotated counterclockwise, the claw portion touching the upper part of the protrusion 6 can be released. The engaging member 7 is moved upward using the engaging member 7b as a fulcrum, but at this time the claw portion 7b pushes the bent piece 2b to the left in FIG. 2, causing it to elastically deform. Can be canceled.

In the above description, the present invention has mainly been described as a buckle attached to a watch band or the like, but it may also be used as a buckle on a bracelet or a waist belt, and is not limited to the above embodiments.

As described in detail above, in the buckle for a watch band or the like according to this invention, the engagement member 7, which includes the engagement recess 7a, the claw 7b, and the lever 9, is attached to the free end of the presser metal fitting 5 by the pivot pin. 8
By simply pressing the presser metal fitting 5 against the buckle main body 2, the protrusion 6 provided on the bent piece 2b is engaged with the engagement recess 7a, and the presser metal fitting 5 is attached to the buckle main body 2.
When the free end of the is fixed and the engaging member 7 is rotated by operating the lever 9 in the above-mentioned fixed state, the engaging member is moved upward using the claw portion 7b touching the upper part of the protrusion 6 as a fulcrum. At the same time, the claw portion 7b presses the bent piece 2b inward and elastically deforms it, so that the free end of the presser metal fitting 5 can not only be easily fixed to the buckle main body 2, but also This can be easily and accurately separated from the buckle main body 2.

Moreover, since the presser metal fitting 5 can be easily removed from the protrusion 6 of the buckle body 2 by operating the lever 9, it is possible to enlarge the protrusion 6 and the engagement recess 7a to strengthen the fixing force and obtain a highly reliable buckle. can.
