Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band mounting structure.

[0002]

2. Description of the Related Art As a band used for equipment such as a wristwatch, there has been known a band which is entirely formed of resin and has a mesh metal bracket connected to an end thereof. The band is firmly attached to the device by attaching a bracket to the band attachment portion of the device such as a wrist watch. The band having such a structure has a bracket set in a molding die,
It is manufactured by insert molding in which a resin is injected into a mold and cured.

[0003]

Since the band having the above-described structure is integrated with the bracket by insert molding, the mold used for molding becomes complicated and the manufacturing is troublesome. Moreover, since the band and the bracket are integrated, when the band is replaced due to wear or deterioration, it is necessary to replace the bracket together, and the bracket is wasted. In addition, since the band and the bracket cannot be exchanged with each other, there is an inconvenience that they cannot be used for interesting changes.

The present invention has been made in consideration of such circumstances, and the band can be easily manufactured.
An object of the present invention is to provide a band mounting structure that is strong in mounting and can be easily replaced.

[0005]

A band mounting structure of the present invention is a device case having a band mounting portion, and a cover mounted on the band mounting portion of the device case at an angle downward from the device case. A member, a guide hole formed in the cover member for guiding the tip of the band so as to reach the band mounting portion of the device case, and a hard member, and prior to insertion of the band into the guide hole. A spacer that is press-fitted into the guide hole and is located between the cover member and the band; and a mounting member that mounts the tip end portion of the band inserted into the guide hole of the cover member to the band mounting portion of the device case. It is characterized by

In this structure, the spacer is positioned between the cover member and the band by pressing the spacer into the guide hole of the cover member and then inserting the band into the guide hole of the cover member. Is linked to. Then, the cover member is aligned with the band attachment portion of the device case, and the tip end portion of the band is connected to the band attachment portion of the device case by the attachment member, whereby the attachment to the device case is performed.

In such a structure, since the cover member and the band are separate bodies, even if the band is resin,
Since it is sufficient to manufacture only the band as a single item, the band can be manufactured easily, and the cover member and the band can be interchanged with each other, which enables various variations in use. In this case, since the cover member is attached to the device case at an angle toward the lower side of the device case, impact resistance can be imparted to the lower surface of the device case.

In the present invention, by forming an opening in the cover member that exposes a part of the spacer, the spacer can be visually recognized through the opening. This also improves the design.

1 to 5 show an embodiment of the present invention.
In this embodiment, the present invention is applied to a wrist watch,
The band 1 is attached to the device case 2 in the 6 o'clock and 12 o'clock directions. The equipment case 2 constitutes a wristwatch case, inside which a timepiece module 3 having a dial and the like is arranged, a timepiece glass 4 is attached to the upper surface, and a lower surface is sealed with a back cover 5. On the other hand, the band 1 is formed by injection molding a resin such as urethane. In the illustrated example, the band 1 is formed in a wavy shape in which the portion excluding the tip portion 1a is continuous, and thereby the aesthetic appearance is improved and the entertaining property is imparted. A cover member 6 and a spacer 7 are used to attach the band 1 to the device case 2.

The cover member 6 is attached to the band attaching portion 8 of the device case 2, and an attaching opening 6a into which the band attaching portion 8 is fitted is formed at an end portion on the device case 2 side. The cover member 6 is attached at an angle to the device case 2 so as to extend from the band attachment portion 8 obliquely downward of the device case 2.
By extending the cover member 6 below the device case 2 in this manner, the lower part of the device case 2 is protected from impact, and thereby impact resistance is imparted. Further, impact resistance can be further imparted by molding the cover member 6 with a soft resin such as urethane resin.

The cover member 6 is formed with a guide hole 9 which communicates with the mounting opening 6a.
The spacer 7 and the band 1 are inserted into. The guide hole 9 is formed so as to be parallel to the length direction of the cover member 6, that is, to be inclined downward with respect to the device case 2. The band mounting portion 8 of the device case 2 is formed with engagement holes (not shown) into which both ends of a mounting member 10 described later are engaged.

The spacer 7 is pressed into the guide hole 9 of the cover member 6. FIG. 3 shows this spacer 7, which is an extension piece 7a extending in the direction of the equipment case 2 and a lip piece 7 bent at right angles from both sides of a flat plate portion connected from the extension piece 7a.
It is formed in a substantially U-shape with b. The spacer 7 is formed of a metal in the shape shown in the figure, and is press-fitted into the guide hole 9 of the cover member 6 to be integrated with the cover member 6 to give strength to the cover member 6 and the band 1 and the device. The extension piece 7a covers the upper portion of the band 1 while protecting the attachment portion to the case 2. The spacer 7 is press-fitted into the guide hole 9 and assembled before the band 1 is press-fitted into the guide hole 9 of the cover member 6. The lip piece 7b is the extension piece 7a.
It is provided so as to be located on the rear side with respect to this, and thereby interference with the mounting member 10 is prevented.

The band 1 has a through hole penetrating in the width direction (see FIG. 4).
Reference numeral 12) in FIG. 2 is formed at the tip end portion thereof, and the mounting member 10 is inserted into the through hole 12. Mounting member 1
As 0, a spring rod used in general wrist watches can be selected. Although this spring rod is not shown, the spring is inserted inside the cylindrical pin, and the engagement pins are arranged on both sides of the spring. Engage in the two engaging holes. As a result, the band 1 is attached to the device case 2. A stopper step 11 is formed at the end of the band 1 on the device case side (see FIG. 1). The stopper step portion 11 is formed by widening a portion of the band 1 in front of that, and thereby comes into contact with the end surfaces of the cover member 6 and the spacer 7. Due to the contact of the stopper step portion 11, the cover member 6 and the spacer 7 are prevented from being displaced in the length direction of the band 1, and these can be assembled to the device case 1.

FIG. 4 shows the assembly of the main character, in which the spacer 7 is pressed into the guide hole 9 of the cover member 6 to integrate them. After that, the tip portion 1a of the band 1 is press-fitted into the spacer 7, whereby the cover member 6, the spacer 7 and the band 1 are integrated. In this state, the through hole 12 of the band 1
A mounting member 10 such as a spring rod is inserted through the above, and the mounting opening 6a of the cover member 6 is fitted to the band mounting portion 8 of the device case 2, as shown in FIG. As a result, the mounting member 10
Is engaged with the engagement hole of the device case 2, so that the device case 2
The attachment of the band 1 to is completed. At this time, the surface 16 of the cover member 6 is attached so as to press the end portion of the back cover 5 to prevent the back cover 5 from coming off.

In this embodiment, since the cover member 6, the spacer 7 and the band 1 are separate components, it is sufficient to manufacture the band 1 independently, which facilitates the manufacture of the band 1. In addition, since the cover member 6, the spacer 7 and the band 1 can be separated, they can be exchanged with each other, and can be used in a variety of ways. The members are not wasted.

1 and 2, reference numeral 15 is an opening formed in the cover member 6. As shown in FIG. 5, the opening 15 is formed in a substantially rectangular shape on the upper surface of the cover member 6 to give the cover member 6 a design.
Further, the metal spacer 7 press-fitted into the opening 15 or the inside of the cover member 6 is exposed, and the spacer 7 can be visually recognized through the opening 15. Therefore, the toughness and glossiness of the metallic spacer 7 can be added to the soft image of the resin cover member 6, and the designability is further improved.

The present invention can be variously modified without being limited to the above embodiments, and can be applied to, for example, devices other than a wristwatch. Further, the surface of the spacer 7 may be colored or a marking treatment may be applied to improve the design.

[0018]
