BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an additional device for a watch band which is mounted on a wristwatch band.

[0002]

2. Description of the Related Art Conventional watch band additional devices include:
The one shown in FIG. 24 is known (Japanese Patent Laid-Open No. 9-7443).
No. 5). That is, the wristwatch 90 is a watch body 91
And a band 92 attached to both ends of the watch body 91
a and 92b, and an additional device 93 is mounted on one of the bands 92b. The additional device 93 includes a case body 94 having a built-in vibration caller for a mobile phone, and a band fixing plate 95 disposed on the back side of the case body 94.
It is composed of The band fixing plate 95 is made of a leaf spring having a substantially U-shaped cross section. The band fixing plate 95 is rotatably supported by the case body 94 by a curl portion 95 a provided at one end thereof, and is formed at the other end thereof. Is provided with a protruding portion 95b that can be disengaged from a notch portion 94a provided on the case body 94.

When the additional device 93 is fixed to the band 92b, as shown in FIG.
5 is disengaged from the notch 94a of the case body 94, and the band fixing plate 95 is rotated in a direction away from the back surface of the case body 94. After a while, the band 92
b is positioned on the back surface of the case body 94, and in this state, after the band fixing plate 95 is rotated in the opposite direction to the above, the protrusion 95b is engaged with the notch 94a. As a result, the band 92 b is connected to the back of the case body 94 and the band fixing plate 95.

A second portion that is narrow and thick in the direction, and a third portion that is provided at the distal end of the second portion and that is locked to the case body. Therefore, stable wearing performance is obtained by the wide first portion being in close contact with the band of the wristwatch, and the third portion is engaged by the second portion being narrow in the direction of the tip. At the time of stopping, it is easy to pick and work can be easily performed.

When the wide portion and the narrow portion coexist in the band-shaped member, not only stress is concentrated on a specific portion when the band-shaped member is extended, but also a crack may occur in the specific portion. However, since the thickness of the second portion is increased in inverse proportion to the width, the band-shaped member also expands and contracts uniformly at this portion. Therefore, even if the wide portion and the narrow portion coexist in the band-shaped member, the applicable range of attachment is not narrowed, and there is no possibility that a crack is generated in a specific portion, and a stable mounting state without trouble and easy mounting work. And balancing.

According to the ninth aspect of the present invention, the locking means includes a locking portion provided outside the case body and the locking portion provided at an end of the band-shaped member. And an engaged portion to be engaged. Therefore, even when the case body is composed of the lower case and the upper case, the wristwatch can be mounted on the wristband without separating the two cases.

Further, in the invention according to claim 10,
The device means is an incoming call detection alarm which detects an incoming call of the portable terminal and notifies the user of the incoming call. Therefore, an incoming call detection alarm that can be attached even if the wristwatch band is wider than the case main body or has various thicknesses of the wristwatch band and that can provide a comfortable wearing feeling without any discomfort is achieved.

When attaching the additional device 4 composed of the case body 5 and the belt 6 to the band 3b of the wristwatch 1, it is provided on the right hook 30 of the upper case 8, as shown in FIG. Insert a flathead screwdriver d into the open operation section 30b and rotate it. Thereby, the locking projection 2
The engagement between the locking recess 30a and the locking recess 30a is released, and the one ends of the two cases 7, 8 can be easily opened. next,
From one end side of the open cases 7 and 8, the belt 6
Of the head 34 of the wristwatch 1
The band 3b is inserted between the lower case 7 and the belt 6 by being turned around to the back side of the band 3b.

Thereafter, in the same manner as described above, one head 34 of the belt 6 is connected to the right stopper pieces 18 of the lower case 7.
And the neck 34 is press-fitted between the right stopper pieces 18, 18. Next, when the other end of the upper case 8 is rotated downward, the right hook 30 provided on the upper case 8 comes into pressure contact with the outside of the right hook 20 provided on the lower case 7, and then the right and left hooks are provided. The locking projections 20a of the hooks 20, 30 engage with the locking recesses 30a. As a result, the two cases 7, 8 are fitted again, and the belt 6 is placed between the lower case 7 and the band 3b.
The other end is engaged with the case body 5 while the additional device 4 is inserted into the band 3b.

When the additional device 4 is mounted, the belt 6 is formed of an elastic material having a large friction coefficient such as silicon rubber as described above, so that the additional device 4 is hardly displaced from the band 3b. A stable attachment state is obtained, and it is possible to prevent a deterioration in a feeling of wearing caused by a shift or displacement of the additional device 4 beforehand.

The belt 3b can be expanded and contracted, so that the band 3b is wider than the case body 5,
Even if the thickness of the band 3b to be attached is variously different, attachment becomes possible, and excellent versatility can be secured. Furthermore, since the torso 31 which comes into contact with the skin of the arm while the wristwatch 1 is worn on the arm is wide and elastic and flexible, it does not interfere with the skin and is good without any discomfort. A comfortable wearing feeling can be maintained.

Further, since the belt 6 is formed of a material having high toughness such as silicon rubber, it is possible to use a mold to form a small shape having a high degree of freedom. Therefore, in combination with the degree of freedom in molding the resin used for molding the cases 7 and 8, it is possible to provide an additional device which is extremely small and is optimal for being added to the wristwatch 1 for use.

In addition, since the shoulder 32 of the belt 6 has a narrow tip, the neck 33 can be easily picked up and the mounting operation can be easily performed. On the other hand, since the body 31 has a wide shape, a stable mounting state is obtained as described above, and therefore, a stable mounting state and simplification of mounting work can be achieved at the same time.

When the wide portion and the narrow portion coexist in the belt 6 as described above, stress is concentrated on a specific portion when the belt 6 is extended, so that not only the applicable range which can be mounted is narrowed, but also the specific portion is narrowed. There is also a risk that cracks will occur in the steel. However, in the present embodiment, since the thickness of the shoulder portion 32, whose width changes, is changed in inverse proportion to the width, the belt also expands and contracts uniformly at this portion. Therefore, even if the wide portion and the narrow portion coexist on the belt 6, there is no possibility that the applicable range of attachment is narrowed or a crack is generated in a specific portion. Can be compatible.

Further, the notches 12a,
The opening formed by 13a is closed by the close contact of the head 34 and the neck 33 having the same elasticity as the other parts of the belt 6, so that the drip-proof property can be secured.

FIGS. 20 to 23 show another embodiment of the present invention. In this embodiment, the fitting structure of the lower case 7 and the upper case 8 is the same as that of the above embodiment. is there. However, unlike the above embodiment, the two cases 7 and 8 in the present embodiment have the notches 12a,
13a is not provided, and both cases 7, 8 are fitted in a sealed state. In addition, holders 40 and 40 are integrally formed at corresponding portions on the outer surface on the short side of the upper case 8. The holders 40, 40 are opposed to each other and extend in the up-down direction, and oppose walls 40a, 40a having a substantially J-shaped horizontal cross section.
And the substantially horizontal support walls 40b, 40b provided at the lower ends of the opposing walls 40a, 40a.

The belt 6 is made of the same material as that of the above embodiment, and the holder 40 is provided at both ends.
Are provided between the opposite walls 40a, 40a, and the projecting portions 6a whose both ends can contact the support walls 40b, 40b are provided.

In this embodiment, when attaching to the band 3a of the wristwatch 1, one of the protrusions 6a is removed from the holder 40, and the belt 6 is attached to the wristwatch 1.
After turning the band 3b to the back side of the band 3b,
Into the holder 40. Thus, the band 3b of the wristwatch 1 is sandwiched between the belt 6 and the lower surface of the lower case 7, and the additional device 4 is fixed to the band 3b of the wristwatch 1.
Therefore, in this embodiment, when the wristwatch 1 is mounted on the band 3b, it is not necessary to separate the two cases 7, 8 so that the work at the time of mounting is facilitated and the drip-proof property is easily ensured.

In the embodiment, the incoming call detection alarm of the portable terminal is accommodated and arranged inside the case body. However, the present invention is not limited to this, and other electronic devices and the like may be accommodated and arranged. Good.

[0045]

As described above, according to the present invention, since the band-shaped member is extendable and contractible, it can be attached even if the band of the object to be attached or the wristwatch is wider than the case body or has a different thickness. Excellent versatility can be secured. Further, since the band-shaped member has toughness, even when the band-shaped member comes into contact with the skin of the arm while the wristwatch is worn on the arm, the band-shaped member does not interfere with the skin, and a comfortable feeling of wearing is obtained. be able to.

Further, the case body is composed of a lower case and an upper case which are detachably fitted to each other, and the locking portions formed at both ends of the band-like member are fitted inside the two cases by fitting the two cases. Therefore, there is no need to provide a structure for locking the band-shaped member outside the case body composed of the lower case and the upper case, so that the outer surface of the case body is smooth without projections. With such a configuration, it is possible to prevent interference with clothes and the like.

Further, since a portion which is compressed and deformed in accordance with the narrow pressure is provided in a portion of the belt-shaped member which is narrowed due to the fitting of the two cases, the portion which is compressed by the narrow pressure of the band-shaped member is provided. The drip-proof effect can be generated by the compression deformation.

Further, since the locking portion is formed integrally with the band-shaped member and is made thicker than other portions, the locking portion can be formed easily and at low cost by molding using a mold. A belt-shaped member having a portion can be manufactured, and since the locking portion is thick, it is possible to obtain a locking portion that does not hinder deformation due to a tensile force during mounting.

The band-like member has a wide first portion provided at the center portion, and a second portion extending on both sides of the first portion and gradually narrowing and thickening toward the distal end portion. And a third portion provided at the distal end of the second portion and locked to the case body is integrally formed. Therefore, stable wearing performance is obtained by the wide first portion being in close contact with the band of the watch, and the third portion is engaged by the narrow width of the second portion in the direction of the tip. At the time of stopping, it is easy to pick and work can be easily performed. When the wide portion and the narrow portion coexist in the band-shaped member as described above, not only stress is concentrated on a specific portion when the band-shaped member is extended, but also a crack may be generated on the specific portion. However, since the thickness of the second portion is increased in inverse proportion to the width, the band-shaped member also expands and contracts uniformly at this portion. Therefore, even if the wide portion and the narrow portion coexist in the band-shaped member, the applicable range of attachment is not narrowed, and there is no possibility that a crack is generated in a specific portion, and a stable mounting state without trouble and easy mounting work. Can be compatible.

The locking means comprises a locking portion provided outside the case body and a locked portion provided at an end of the band-shaped member and engaged with the locking portion. Thus, even when the case body is composed of the lower case and the upper case, the wristwatch can be mounted on the wristband without separating the two cases.

In addition, since an incoming call detection alarm for detecting an incoming call of the portable terminal and notifying it is built in the case body, the band of the wristwatch is wider than the case body, It is possible to achieve an incoming-call detection alarm that can be attached even if the thickness of the terminal is variously different and that can provide a comfortable wearing feeling.
