Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wristwatch whose outer periphery is integrally formed with a leather and synthetic resin band.

[Conventional technology]

Conventionally, on the wristwatch side, a band made of leather, synthetic resin, etc. connected the outer circumference of the body and formed a side element, which was rarely done. Although there have been some examples, the main method has been to fix a synthetic resin band to the upper surface of the body with adhesive.

[Problem that the invention attempts to solve]

However, with the above-mentioned conventional technology, when the body is viewed from the side, the band is simply placed on the top of the body, and there is no sense of unity, and the appearance of the exterior, which is an important point, is undesirable, giving the impression that the band is simply worn. .

Furthermore, the adhesive must be removed for replacement during after-sales service, which is extremely difficult.

The present invention is intended to solve these problems, and its purpose is to provide a design with a sense of unity, softness, and excellent color tone variety, to make it extremely easy to replace the band, and to reduce the cost of the body and back cover. We provide watches that are possible.

[Means to solve the problem]

The wristwatch side of the present invention includes a body 1 made of metal in which a movement 9 is housed, a back cover 2 made of metal and attached to the body 1 with screws 5, and a band made of leather and synthetic resin that is attached and fixed to the back cover 2. 3
The back cover 2 has a bottom part 2c that covers the back of the body 1, a side wall part 2b bent at a position outward from the outer surface of the body 1, and the side wall part 2b.
A collar portion 2a is formed, the tip of which extends outward in a right angle direction, and the band 3 includes an engaging portion 3a attached to and covered by the collar portion 2a and disposed at an outer peripheral position of the body 1; The engaging portion 3a extends outward in the 12 o'clock direction and the 6 o'clock direction of the body 1, and
and a band portion 3b that is integrally configured.

〔Example〕

The present invention will be explained below based on the drawings.

Figure 1 is a plan view showing an embodiment of the present invention, Figure 2 is a plan view showing an embodiment of the present invention;
Fig. 5 is a sectional view showing an embodiment of the present invention, Fig. 3 is a sectional view showing an embodiment of the present invention.
4 are perspective views showing an embodiment of the present invention, and FIGS. 2, 3, and 4 show the same embodiment.

In the present invention, as shown in FIG. 1, the entire outer periphery of the wristwatch body is made of a soft material that is integrally formed with the band, and the side surface shape is also completely covered as shown in FIG. Figure 1: The colored part is an integral band made of leather, synthetic resin, etc., and there is a metal body inside, so a balance between the two makes it possible to create a luxurious and innovative design. Furthermore, as shown in FIG. 1, the outer shape may also be non-circular. The following embodiments will be explained using the non-circular case shown in FIG. 1 as an example.

In FIGS. 2, 3, and 4, 1 is a metal body, and 2 is a metal back cover. Before being integrated with the band 3, the back cover 2 has the shape shown in FIG. A bottom part 2c that covers the back of the body 1, a side wall part 2b bent at a position outward from the outer surface of the body 1, and a tip of the side wall part 2b extending outward in a right angle direction. This forms a flange portion 2a. A band 3 made of leather or synthetic resin is attached to the brim 2a and covered with an engaging part 3a disposed on the outer periphery of the body 1, and an engaging part 3a disposed on the outer periphery of the body 1, and outwardly in the 12 o'clock direction and the 6 o'clock direction of the body 1, respectively. The engaging portion 3a is extended and the engaging portion 3a
and a band portion 3b which is integrally formed, and are integrated as shown in FIG.

Regarding the method of integrally fixing the band 3 and the back cover 2, if the band 3 is made of leather, the back cover 2
If the band 3 is made of synthetic resin, the back cover 2 may be integrally molded when the band 3 is injection molded. A seal 4 is compressed and locked between the case 1 and the case back 2, and prevents water from entering the inside of the watch body from this part. 6 is glass, 7 is dial, 8
is the middle frame, 9 is the movement, and 10 is the axis. Reference numeral 11 denotes a gasket, which prevents water from entering the inside of the watch body from the crown. 12
is a pipe and is fixed to the body 1 by adhesive or the like. A screw 5 has the function of tightening and fixing the back cover 2 to the body. Although there are four screws 5 in FIG. 3, there may be a plurality of screws other than four.

FIG. 5 shows another embodiment of the present invention, in which the outer periphery of the back cover 52 is bent to form a flange 52a as shown in the figure, to prevent the band from coming off the back cover. It has a hooking effect.

As shown in FIG. 3, the method of assembling the side according to the present invention is to set the gasket 4 on the body 1 in which the dial 7, movement 9, inner frame 8, crown 10, gasket 11, etc. are set, and then The case is completed by placing the integrated back cover 2 and band 3 on top and tightening the screws 5.

[Effect of idea]

According to the invention described above, the functional part of the wristwatch is made of metal, and the outer periphery is covered with a leather or synthetic resin material that is integrated with the band.
Compared to a side made entirely of synthetic resin, it provides sufficient strength in terms of functionality, and also has a softer appearance, making it possible to create a variety of leathers and change the color tone. In addition, since the back cover and body are engaged with a screw fixing structure from the back side of the back cover, the shape of the back cover and body is simpler and easier to process than the conventional dowel structure with dowels or screw fixing structure. Mast down can be achieved. In particular, in the conventional method of fixing the band, the band, sides, body, back cover, etc. were completely separate parts, so the structure was such that a hole for attaching the band was formed on the body and it was fixed to the body via a spring bar, which required a large amount of machining. However, according to the present invention, the body can be formed into a uniform ring shape, and attachment/detachment to/from the side of the band is possible using the collar provided at the tip of the outer periphery of the back cover and the above. It is extremely easy to attach and cover the engagement part on the brim, and since the back cover band is attached, the band can be replaced by removing the back cover with a screw and attaching a new back cover with a band to the body. and
Therefore, it has the effect of achieving excellent workability and rationalization in band replacement.
