Description

[Detailed Description of the Invention] The present invention relates to a band attachment structure for attaching portable devices such as wristwatches, game watches, and small information devices to the wrist.

Conventionally, in order to attach a band to a wristwatch, a leg was protruded from the side of the watch case, and the end of the band was attached to this leg. On the other hand, the size of the wristwatch itself is limited by the width of the wrist. Therefore, as mentioned above, by having the feet protrude to the side of the case, the size of the module and display section within the case is further restricted by the feet.

An object of the present invention is to provide a band attachment structure for a portable device that allows the area of modules and display parts to be increased.

In order to achieve the above object, the present invention is characterized in that a leg for attaching a band is integrally provided on the back side of the back cover of a case of a portable device such as a wristwatch.

Hereinafter, an example in which the present invention is implemented in a wristwatch will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, a wristwatch case 1 has a glass 3 attached to the upper part of a body 2, and a back cover 4 attached to the lower side of the body 2. As shown in FIG. 2, this back cover 4 has a rectangular planar shape,
It consists of a central body 4a, both inclined parts 4b, an upper part 5, and rising engagement pieces 6 at both ends.
As shown in FIG. 4, a stepped portion 2a is formed in which the main body 4a, the inclined portion 4b, and the upper portion 5 engage, and the back cover engages in this portion. The engagement piece 6 is provided with an engagement protrusion 7, the engagement piece 6 is inserted into a notch 8 formed on both lower sides of the body 2, and the engagement protrusion 7 is inserted into an engagement recess 9 formed on the body 2. resiliently engaged and removably attached. In this watch case 1, band attachment legs 10 are bent and provided on both sides of the back surface of each upper portion 5 of the back cover 4. Each band attachment leg 10 is formed at a height that is approximately equal to the depth of the upper portion 5, that is, such that the tip of the leg 10 is approximately equal to the central body portion 4a of the back cover 4. A hole 11 for locking a spring bar is formed in each band attachment leg 10.

Therefore, the spring rod 13 inserted through the end of the band 12
The band 12 can be attached to the watch case 1 by engaging the holes 11 of the band attachment legs 10. When the wristwatch is worn on the wrist using the band 12, if the height of the leg portion 10 is set to approximately match the depth of the upper portion 5 as described above,
There is no risk of hurting your wrist.

As is clear from the above, according to the present invention, the leg portion for attaching the band is integrally provided on the back side of the back cover of the case of a portable device such as a wristwatch. Therefore, the case can be made larger, which has the advantage of increasing the area of the modules and the display section housed inside the case.

In addition, the back cover includes the main body, inclined part, upper part, engaging piece,
It consists of an engaging protrusion and a band attachment leg, which can be easily made from a flat plate by press working.

Moreover, since the band attachment leg has a simple structure of just bending downward, the cost is much lower than previous structures.

Furthermore, since the main body, sloped part, and upper part of the case back are housed in the stepped part of the case, the thickness of the watch can be reduced.
