Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention tool capable of preventing a portable wireless device having a folding structure from falling and a strap equipped with the fall prevention tool.

[0002]

2. Description of the Related Art Conventionally, in a portable wireless device having a folding structure, in order to prevent the portable wireless device from falling backward when it is in an open state, a first housing (hereinafter, referred to as an upper part) having a display portion is provided. The second housing (hereinafter, referred to as the lower housing) having the operation unit is made larger or heavier than the first housing.

[0003]

However, for example, in a mobile wireless device having a function of a portable videophone having an image pickup unit in the upper casing, the image displayed on the display unit of the upper casing is visually recognized. In order to make it easier, it is conceivable to change and adjust the upper casing to various inclination angles, but in this case, if the weight balance of both casings is poor,
The upper case may fall backward.

Further, generally, in order to improve the appearance design of the portable wireless device, it is found that a curved surface is frequently used. For example, the outer surface portion corresponding to the bottom surface of the lower housing has a curved shape. However, there is a possibility that the feeling of stability becomes poor and that the object becomes unstable and easily falls.

Further, normally, when the upper housing is opened and tilted, the upper housing can be stopped at the angle when the housing is opened and the tilted state can be held at that angle, but the holding force is mainly due to the friction of the hinge portion. For example, when the frictional force is reduced by repeatedly opening and closing both housings for a long period of time, the tilted state may not be maintained.

In view of the above-mentioned circumstances, the present invention can prevent the folding portable wireless device with a camera from falling backwards when necessary and is always stable even when used for a long period of time. It is an object of the present invention to provide a fall-prevention tool capable of holding the inclined angle and a strap including the fall-prevention tool.

[0007]

A fall prevention tool according to the present invention is, firstly, a main body having a first casing provided with a display portion and a second casing provided with an operating portion, and these casings. A fall-prevention tool detachably attached to a folding portable wireless device, comprising: a hinge part for connecting a body in a foldable state, at least an outer surface side of the first casing or the second casing. And a means for supporting the first casing or the second casing by detachably locking the first casing or the second casing.

With this tip-over prevention tool, the second housing is placed on a flat surface such as a desk and the first housing can be securely tilted to the top surface of the desk or the like when used at any angle. Therefore, the folding portable wireless device itself can be prevented from falling.

Secondly, the fall-prevention device has the first structure when the second housing is placed on a flat surface such as a desk.
It is preferable to have an abutting portion that abuts against the casing from the outer surface side and fixes the inclination angle of the first casing in a state of being inclined at a constant angle with respect to the plane.

With this, the fall prevention device can support the first casing from the outer surface, and the first casing is pushed down by its own weight and is rotated rearward to keep the inclination angle constant. You can prevent problems such as being unable to do so. As a result, it is possible to securely fix the first housing having the display at an inclination angle that is easily visible to the user.

Thirdly, the fall prevention tool of the present invention is
The first housing provided with a display unit and the second housing provided with an operation unit
A main body having a casing, a hinge portion connecting the casings in a foldable state, and a convex portion formed on the outer surface side of each of the first casing and the second casing. A fall prevention tool for a folding portable wireless device, characterized in that the fall prevention tool is detachably attached to the convex portion on the side of the first casing or the second casing.

Accordingly, if the folding portable wireless device is formed with a convex portion in advance, for example, a convex portion for fixing the opening angle (hinge angle) between the first casing and the second casing is provided. Since it becomes possible to wear the fall prevention device by using it, it is not necessary to bother to partially change the shape of the folding portable wireless device for mounting the fall prevention device.

Fourthly, the fall prevention tool of the present invention is
A main body having a first casing and a second casing, a hinge portion connecting the casings in a foldable state, and a charging device for charging the portable wireless device on the second casing side. A fall prevention tool for a folding portable wireless device, comprising a recess for fixing to a base, characterized in that it is detachably attached to the recess on the second casing side.

Thus, if the charging stand has a recess formed in advance, it is possible to mount the fall-prevention tool by using this recess, so that it can be folded and carried for mounting the fall-prevention tool. Avoid changing the shape of wireless devices.

Fifth, the fall prevention device of the present invention is
It is preferable that the first and second casings are supported in the longitudinal direction and are mounted near the center of gravity in the longitudinal direction.

[0016] With this configuration, one fall preventive tool can prevent the housing from moving backward, and at the same time, can fix the display portion provided in the first housing at an arbitrary inclination angle. .

Sixthly, the hand strap of the present invention has a main body having a first casing having a display portion and a second casing having an operating portion, and these casings can be folded. A hand strap for carrying the folding portable wireless device by locking it in a stop hole of the folding portable wireless device having a hinge part connected in a state, and a fall prevention tool for preventing the folding portable wireless device from falling. It is characterized by having.

As a result, the hand strap can be provided with a fall prevention function.

Seventhly, it has a ring-shaped cord and a retaining portion for preventing the cord from falling out of the casing of the folding portable wireless device, and the retaining portion has the fall-down portion. A preventive device may be provided.

Eighthly, it has a ring-shaped cord and a retaining portion for preventing the cord from falling out of the casing of the folding portable wireless device, and the cord is prevented from falling. The tool may be detachably attached.

As a result, whether or not the fall-prevention device is attached to the hand strap can be selectively used by the user, and the selection range is increased.
