DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band mounting structure for mounting a band on a wristwatch-type electronic device or the like mounted on a wrist of a user.

[0002]

2. Description of the Related Art In general, a wristwatch-type electronic device such as an electronic wristwatch has a band mounting portion on a 12 o'clock side and a 6 o'clock side of a case (hereinafter referred to as a device case). It can be worn on the wrist of the user. In such a wristwatch-type electronic device, the size of the device case may be larger than the thickness of the user's wrist, and in this case, the band attaching portion protrudes long from the wrist and comes into contact with the user's body or the like. There is a safety problem. For this reason, conventionally, while shortening the band attachment portion of the device case and forming it into a rounded curved shape so as to bend in the wrist direction, a connection piece is attached to the band attachment portion, and the band is connected via the connection piece. It has a mounting structure. The connection piece is rotatably mounted on the band mounting portion via a pin, so that the band can be wound around the wrist of the user.

[0003]

However, in the conventional band mounting structure via the connecting piece, the connecting piece is easily rotated more than necessary, so that the band is not mounted on the wrist in a free state. The design is far from the curved shape of the band attachment part. That is, since the band is bent in the direction of the back side of the device case so as to form an acute angle from the band mounting portion and excessively wraps around the back side of the device case, it is possible to maintain a shape that is continuous with the curved shape of the band mounting portion. However, the sense of unity between the band and the band mounting portion is impaired, which results in deterioration of the design of the appearance and loss of luxury.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and prevents the band from excessively wrapping around the backside of the equipment case, maintains the integrity of the band and the band mounting portion, and improves the appearance and high quality. An object of the present invention is to provide a band mounting structure that enables product orientation.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a receiving portion protruding in a mounting direction of a back cover and a band is rotatably mounted on a device case formed in a band mounting portion and a band mounting portion of the device case. And a connection piece connected between the end of the band and the device case and the band, and the back cover abuts on the connection piece to rotate the connection piece toward the back side of the device case. It is characterized in that a contact portion for restraining is formed.

[0006]

The connection piece rotatably mounted on the band mounting portion of the equipment case is prevented from rotating in the rear direction of the equipment case by its contact part abutting on the back cover.
For this reason, the band attached to the device case via the connection piece has a shape that is continuous from the band attachment portion without bending at an acute angle in the direction of the back of the device case, and has an external shape with a sense of unity between the band and the band attachment portion Become.

As shown in FIG. 3, the band is slightly rounded from the device case 1 toward the wrist. It is formed in a curved surface shape that bends in a tinged form.

The band mounting portion 3 has a connecting piece 10
A pair of mounting arms 5 and 5 having mounting holes (not shown) for mounting the connection piece 10 formed by inserting both ends of the band mounting pin 4 through which the cable is inserted are formed on both left and right sides. Grooves 6, 6 for inserting connection rings 11, 11 of the connection piece 10, which will be described later, are formed inside the mounting arms 5, 5. In addition, between the grooves 6, 6, the connection ring 11 of the connection piece 10,
A central protruding portion 7 is formed to cover the pins 4 between 11. The protruding portion 7 is formed so as to protrude from the device case 1 in the direction in which the band is mounted. The protrusion amount is set so as to be located on the back side.

FIGS. 4 and 5 show the connecting piece 10. The connection piece 10 is for attaching the band piece 20 shown in FIGS. 6 and 7 to the band attachment portion 3 of the device case 1 and is formed to have an “I” shape when viewed in plan. The connecting piece 10 is a flat ring-shaped connecting ring 1.
1, 11 are provided on both the left and right sides. Connecting ring 11, 1
Numeral 1 is for attaching the device case 1 to the band attaching portion 3 and for connecting the band piece 20. Attachment to the band attaching portion 3 is performed by inserting the pin 4 between the connecting rings 11 and 11 between the one ends 11a.
This is performed by inserting 1a, 11a into the groove 6 (see FIG. 2) of the band mounting portion 3. By this attachment, the connection piece 10 is rotatably connected to the band attachment portion 3.

On the other hand, for connection to the band piece 20, the band-side ends 11 b, 11 b of the connecting rings 11, 11 are inserted into recesses 21 (see FIG. 6) of the band piece 20, and these are connected by the pins 8. This is done by: The upper and lower central portions of the connecting rings 11 and 11 are integrally connected by a connecting plate portion 12. However, the connection piece 10 is attached to the device case 1 so that the connection plate portion 12 faces upward as shown in FIG.

FIGS. 6 and 7 show a band piece 20 connected to the connecting piece 10, which has concave portions 21 and 21 into which ends 11b and 11b of connecting rings 11 and 11 of the connecting piece 10 are inserted. A pin hole 22 into which the pin 8 is inserted is formed. Reference numeral 23 denotes a recess into which an engaging piece (not shown) of an adjacent band piece is inserted and pin-connected. The band piece 20 constitutes an end of a band (not shown), and is attached to the band attaching portion 3 of the device case 1 via the connecting piece 10 as shown in FIG.
