Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device such as a portable recording / reproducing device, a portable telephone, an electronic game, etc., which prevents a portable electronic device from falling from a storage location such as a bag or a pocket of a jacket. The present invention relates to a fall prevention device for an electronic device.

[0002]

2. Description of the Related Art In recent years, the "Walkman" started with a calculator.
Portable recorder / player, portable telephone,
2. Description of the Related Art Portable electronic devices such as electronic games have been remarkably popularized. Further, these portable electronic devices tend to be smaller and lighter. For example, a mobile phone weighs about 150 g. These are carried in a bag or a jacket pocket. In addition, portable electronic devices were housed in a soft case made of synthetic leather, and this case was attached to the waist with a band. However, when the portable electronic device is put in a case and worn on the waist, not only is the operability inconvenient, but also there is a problem that it becomes an obstacle when sitting down. Therefore, the portable electronic device is often stored in a jacket pocket or the like. However, the outer shell of the portable electronic device is formed of a slippery material such as a hard synthetic resin. Therefore, there is a problem that the portable electronic device falls down from its pocket by its own weight when it bends during work or when putting on or taking off the jacket, causing loss, breakage or breakdown. In addition, since the surface is made of a slippery material, when the mobile phone is taken out of the bag, an accident such as slipping from the hand and falling to the ground has occurred.
As a countermeasure against this, a fall prevention device is commercially available in which one end of a coiled string is locked through the string of the outer shell of the mobile phone, and the other end is locked with clothing or a belt.

Further, the following are known as patent applications of conventional fall prevention tools. For example, JP-A-10-
In Japanese Patent No. 257147, a clip is provided on a resilient holder, and the mobile phone body is attached to the holder.
It is described that this is stored in a breast pocket of a jacket and attached to the end of the breast pocket with a clip. further,
Japanese Unexamined Patent Publication No. Hei 8-97896 has a band which is crossed and stopped on both sides, a band which is attached to a waist, and a holder, and the band is connected to the band such that the holder is located on the chest. A portable device having a structure is disclosed.

[0004]

The method of storing portable electronic equipment in a case in advance and attaching it to the waist with a band or the like not only has a problem in operability as described above, but also depends on the type of work. In many cases, work equipment is carried, and there is a case where the user cannot afford to mount portable electronic equipment. In addition, the method of attaching the coiled cord to the portable electronic device and storing it in the breast pocket of work clothes, etc., is because the length of the fall prevention device is insufficient or the fall prevention device itself is stored in the pocket. Not only is it difficult, but on the contrary, it gets in the way when you take it out of your pocket. Furthermore, if this fall prevention tool is protruded from the pocket, there is a problem that it becomes a hindrance in work or the like.

In the method described in Japanese Patent Application Laid-Open No. H10-257147, since the clip is sandwiched between the ends of the pocket, it is troublesome to store or remove the protective device in the pocket. Therefore, there is a high possibility that the protective device will be stored in a pocket without using the protective device. Some breast pockets of currently marketed work clothes are too shallow to use the above protective equipment. In addition, this tendency is greater in women's outerwear than in aesthetics. Further, according to the method described in Japanese Patent Application Laid-Open No. Hei 8-97896, the mobile phone is attached to the body in close contact. Therefore, the belt for mounting passes on both sides. For this reason, it is difficult to wear this from above the work clothes or the like, and it has to be worn under the work clothes. Therefore, at the time of use, it is necessary to release the button of the work clothes or open the zipper to take it out, and there is a problem that it is not possible in time of emergency. In addition, there is a problem that not only the wearing site is limited from the viewpoint of aesthetic appearance, but also it is difficult to use for women due to its structure.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a portable electronic device fall prevention device which has excellent operability, is easy to use, and does not impair the aesthetic appearance at the time of mounting.

[0007]

The invention according to claim 1 is mounted on the outer shell of a portable electronic device main body, and when the outer shell comes into contact with the outer surface of the clothing, the resistance in the contact is determined. This is a fall prevention device for a portable electronic device having a resistance increasing means that is larger than that. As the resistance increasing means, a material made of many convex materials such as a planar fastener (trade name: magic tape), such as a piece of raw rubber having a large sliding contact resistance (coefficient of friction) with cloth, is applied. The outer shell of the portable electronic device is made of, for example, plastic.

According to a second aspect of the present invention, there is provided the portable electronic device according to the first aspect, wherein the resistance increasing means is detachably provided on an outer shell of the portable electronic device main body. . For example, the portable electronic device main body may be sandwiched by a spring plate to which a piece of raw rubber is attached.

[0009]

According to the first and second aspects of the present invention, when the portable electronic device is carried in a pocket or the like of clothes,
Depending on the posture, the portable electronic device may try to fall from the pocket. At this time, the resistance to the force that tries to escape between the pocket and the cloth surface is increased by the resistance increasing means. This is because the outer shell of plastic is slippery with the cloth, whereas the sheet fastener, rubber pieces, etc. have a large coefficient of friction with the cloth and are less slippery. Therefore, it is possible to prevent the portable electronic device from falling.

FIG. 1A shows a state in which the fall prevention device according to one embodiment is mounted on a mobile phone. FIG. 2B is a perspective view of the fall prevention device. FIG. 2A is a perspective view showing a mounted state of a fall prevention device according to another embodiment, and FIG. 2B is a perspective view of the fall prevention device. 3 (a) and 3 (b) are perspective views of a fall prevention device showing still another embodiment of the present invention.
FIG. 4 is a perspective view showing still another embodiment of the present invention.

Hereinafter, a portable telephone, which is a typical example of portable electronic equipment, will be described. FIG. 1A is a perspective view showing a state in which a fall prevention device of a portable electronic device according to an embodiment of the present invention is mounted on a mobile phone. FIG. 1B is a perspective view showing a fall prevention device of a portable electronic device according to an embodiment of the present invention. As shown in FIG. 1A, a main body 1 of the mobile phone is formed in a substantially rectangular parallelepiped shape, and an antenna 2 and a lace portion 3 are provided at an upper end thereof. A string for drop prevention or one end of a string for carrying can be locked to the string fastening portion 3. A fall prevention device 4 is fixed to the rear surface of the plastic main body 1 (the surface on which the operation keys and the like are disposed is the front surface) by fitting. Various keys are provided on the front of the main body 1 as operation surfaces,
Buttons, dials, liquid crystal panel, etc. are provided. The fall prevention device 4 is obtained by using a plate-shaped elastic material (plastic or metal) having a predetermined width as a core material and bending the elastic material into a U-shape. That is, the U-shaped fall prevention device 4 as a whole includes an intermediate portion 4A having substantially the same length as the width of the back surface of the main body 1 and a bent portion continuously bent at approximately 90 degrees at both ends of the intermediate portion 4A. 4B and 4C.
The lengths of the bent portions 4B and 4C are approximately the same as the thickness of the main body 1, and the fall prevention device 4 is fixed to the main body 1 by sandwiching the main body 1 between these bent portions 4B and 4C. That is, the bent portions 4B and 4C are configured to have a predetermined elasticity that urges toward the inside. On the back surface of the intermediate portion 4A of the fall prevention device 4, for example, a convex side member 5 of "magic tape" (a convex member of a convex member and a concave member constituting the magic tape) is adhered. . The convex side member 5 of the magic tape has a rectangular shape with a predetermined area, and is located at a substantially central portion on the back surface of the main body 1.

As shown in FIG. 1A, the U-shaped holder (fall prevention device) 4 is fitted to the back side of the portable telephone body 1 from its open surface. That is, by sandwiching both side surfaces of the main body 1 between the bent portions 4B and 4C,
It is fixed at a predetermined position. As a result, when the portable telephone is inserted into the pocket and carried, the convex side member (friction resistance increasing member) 5 of the fall prevention device 4 comes into contact with the surface of the fabric and generates a large frictional force. Therefore, it is possible to prevent the mobile phone main body 1 from sliding down and falling on the floor or the like. In order to take out the mobile phone from the pocket for transmission / reception or the like, the back surface (projection side member 5) of the main body 1 can be easily taken out by separating it from the surface of the cloth in a substantially vertical direction. Further, as the frictional resistance increasing member, a raw rubber sheet or the like can be used instead of the magic tape.

FIG. 2 shows another embodiment of the present invention. In this embodiment, a plate-like elastic material is not used as a core material, and a cylindrical mounting member partially using an elastic material such as rubber is used as shown in FIG. The fall prevention device 8 is a cylindrical upper mounting member 6A having a predetermined opening area.
And a lower mounting member 6B having the same shape as a bottomed cylinder, and a band member 7 connecting these members. A convex side member 5 of the same magic tape as described above is attached to an intermediate portion of the band member 7. By inserting the main body 1 into the cylindrical portions of the mounting members 6A and 6B, the fall prevention device 8 is mounted on the mobile phone main body 1. In this case, the mounting member 6B on the bottom side prevents the mobile phone body 1 from falling off or shifting. Further, as shown in FIG. 2A, the attachment members 6A and 6B are attached to a portion where no operation button is arranged, for example, to the top and bottom of the mobile phone main body 1. Also in this embodiment, the frictional resistance between the tape and the cloth is increased by the magic tape as in the above-described embodiment, so that the main body 1 does not easily fall off.

Further, as shown in FIG. 3, in still another embodiment, the fall prevention device can be constituted by a bag-shaped case. That is, a transparent and soft film 11 is used for the surface side portion of the case 10 which is a fall prevention device. On the back of the case 10, a convex side material 5 of a magic tape is provided.
(Resistance increasing member) is stuck. When the mobile phone is used, transmission and reception can be performed with the mobile phone inserted into the case 10. Even in the fall prevention device 10 configured as described above, the resistance increasing member 5 increases the frictional resistance with the cloth surface, and prevents the fall from the pocket. Also,
In this case, there is an advantage that the main body 1 is protected by the case. As the convex side material 5 to be used, a magic tape is convenient and desirable in handling, but is not particularly limited.

As shown in FIG. 4, in still another embodiment of the present invention, a raw rubber sheet piece 13 can be attached to the outer shell (outer surface) of the main body 1 for slip prevention. These sheet pieces 13 constitute a fall prevention device. A material having a large coefficient of friction (larger than plastic) with a fabric such as raw rubber is attached with, for example, a double-sided tape. Other operations are the same as those in the above embodiments. As a material for increasing the friction, it is also preferable to use, for example, a corrugated rubber sheet (manufactured by Atom Corporation).

It is also possible to connect the fall prevention device or the portable telephone body to a part of the body (belt or the like) with a coiled string or the like. This is because safety against falling, damage, and the like can be further improved. Further, the non-slip material constituting the main part of the fall prevention device can be attached to a portion of the portable electronic device excluding the operation portion.
A portable recording / reproducing device such as a “Walkman” may be attached to the entire surface since there is no need to urgently put in and out.
The feeling when grasping is improved, which is preferable. Also, if you need to move in and out urgently like a mobile phone,
Easy removal is required to some extent. Therefore, a non-slip is stuck on all or a part of both sides or the back of the mobile phone body. Furthermore, a material whose surface is soft such as synthetic resin such as urethane foam and styrene, felt, rubber, synthetic leather or tanned leather is desirably adhered to a part of the outer shell of the body, preferably in a place such as a side surface where a finger easily touches. . At this time, it is preferable to form a depression for attaching these sheet pieces in advance on the outer shell of the portable electronic device because it is unlikely to be an obstacle when putting in and out.

[0017]

The portable electronic device according to the present invention is excellent in operability and does not impair the original function of the portable electronic device. In addition, even if bent at the work site or the like, since it does not drop from the storage location due to its own weight, the cause of failure due to drop damage is reduced. Also, when the portable electronic device is grasped by hand in an attempt to remove it from the storage location, the familiarity between the hand and the portable electronic device is improved,
The risk of slipping is reduced.
