Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic mobile phone capable of preventing breakage of the mobile phone due to falling on the ground or preventing damage to people and objects caused by dropping the mobile phone from a high place. It is a safety cord.

[0002]

2. Description of the Related Art Conventionally, a portable telephone or a portable telephone case is provided with a hand-held loop-shaped cord through which a wrist can pass. Therefore, the user holds the portable telephone by holding the cord in a loop in the palm of his hand, and also uses the cord by passing it through the wrist in a loop when using the telephone. However, some users carry and use the string without passing through the loop, and other users carry and use the string without grasping or attaching the string.

As described above, when carrying or using a portable telephone without attaching a cord, or when carrying or using a portable telephone without passing a cord in a loop, the hand slips and the portable telephone is dropped and damaged. There are many accidents. In addition, even when the portable telephone is carried and used by passing the cord in a loop, there is an accident that the portable telephone is dropped from the hand at the seam from one operation to the next operation and the portable telephone is dropped and damaged.

[0004] In some cases, the above-mentioned accidental fall of the portable telephone does not fit the telephone simply due to the damage of the telephone. For example, when a mobile phone is dropped from a high place such as a construction site of a building or a balcony of a completed building and the mobile phone is dropped as described above, damage to people and equipment directly under the mobile phone may be considered.

It is to be noted that one end of a stretchable cord is connected to a strap fixing portion of a portable telephone or a portable telephone case as in the present invention, and the other end is connected to and fixed to a belt through a trouser belt for portable use. The technology of the safety cord has not been seen to date.

[0006]

SUMMARY OF THE INVENTION The present invention is intended to prevent the above-mentioned accident of the portable telephone from being dropped and damaged, and to further prevent the portable telephone from being damaged by dropping the portable telephone. It is a safety cord for mobile phones.

[0007]

According to the present invention, there is provided a cord connected to a portable telephone or a portable telephone case, the cord being a stretchable cord having a length of not less than an upper body and not more than a lower body when extended. One end of the cord is connected to the strap of the mobile phone or the mobile phone case, and the other end is connected and fixed to the belt of the pants or the belt, and when not in use, the strap shrinks and fits near the waist of the body together with the mobile phone, At the time of use, the cord is extended and the mobile phone can be easily moved to the ear / mouth,
This is a safety strap for a mobile phone, characterized in that if the mobile phone is dropped, the string stops growing before reaching the ground, and can be prevented from dropping and breaking.

Further, the present invention relates to a cord connected to a portable telephone or a portable telephone case, wherein the cord is a coil-shaped stretchable cord having a length of not less than an upper body and not more than a lower body when extended. One end of the cord is connected to the strap of the mobile phone or mobile phone case, and the other end is connected and fixed to the belt of the pants or the belt. When not in use, the strap shrinks into a coil shape and the vicinity of the waist of the body together with the mobile phone. The mobile phone can be easily moved to the ears and the mouth when used, and if the mobile phone is dropped, the strap stops growing before it reaches the ground, preventing drop damage. It is a safety cord for mobile phones.

In the present invention, the boundary between the upper body and the lower body is the waist belt position, the upper body is the distance from the belt position to the mouth, and the lower body is the distance from the belt position to the sole. Regarding the length of the string at the time of elongation, in the case of a coil-shaped string, it does not refer to the entire length of the string, but to the length on a perpendicular line. That is, the degree of elongation (= extension length by pulling) of the coiled string differs depending on the ease of elongation (= elongation) of the coiled string itself and the gravity of the mobile phone that falls, so that the coil is completely formed. This is because, as shown in FIG. 2, it often stops in a spiral state with a long cycle in the middle. Hereinafter, the mobile phone safety cord will be described in detail.

[0010] The safety cord is a cord that connects the mobile phone to a part of the body, usually the waist, and is intended to prevent the mobile phone from being damaged by dropping during use or being carried, or to prevent a person or person from falling. To prevent damage to equipment.
As another effect of the safety cord, since the safety cord is always connected and fixed to the body and carried, the mobile phone is not left behind.

In order to achieve the above object, the first point is the length of the safety cord when it is extended. A convenient body part for carrying a mobile phone is usually the waist. The waist has a belt or a belt for trousers or skirts, which is convenient for connection and fixing. On the other hand, there are many cases in which a mobile phone case is carried by being passed through a belt or hooked on a belt. In this case, one end of the safety cord is connected to a strap of a mobile phone or a mobile phone case with a hook or the like, and the other end is connected and fixed to a belt or a belt of a trouser or skirt with a hook or the like. At the time of use, the cord needs to have a length equal to or longer than the upper body so that the mobile phone can be easily moved to the ears and the mouth so that a telephone call can be made while the other end is connected and fixed to a belt loop or the like.

On the other hand, if the mobile phone is dropped during use or while being carried, the cord should be extended to a length below the lower body so that the cord does not reach the ground and the portable phone does not reach the ground to prevent falling damage. Need to be It should be noted that the degree of elongation (= extension length by pulling) of the cord when extending in the lower body direction depends on the ease of elongation (= elongation) of the cord itself and the gravity of the falling mobile phone. Therefore, it is preferable to determine the length of the cord in the lower body direction when the cord is extended by performing a stretching test using a cord to be used in advance and a mobile phone to be used or the same heavy object.

[0013] As described above, the length of the safety strap is in the range from the upper body to the lower body when stretched. However, since there are those who have particularly high extension and those who have particularly low extension, the length of the safety strap is adjusted. It is also possible to provide a connection hook for adjustment at one or two places in the middle of the cord so that the hook of the terminal can be moved and the length can be adjusted.

The second point is that the length of the safety cord is stretchable and does not disturb the carrying when the telephone is not used, that is, about 20 cm.
It fits below. As described in the first point above, when the phone is used, that is, when the phone is extended, the safety strap needs to have a length ranging from the upper body to the lower body, but the length of such a range becomes several tens of centimeters or more. If it is in the extended state when not in use, it is too long and inconvenient to carry. Therefore, as in the present invention, it is necessary to provide a stretchable cord which can be contracted and shortened when the telephone is not used, and can be expanded to a required length when the telephone is used.

The safety cord of the present invention may be in the form of one thick long fiber, a plurality of thin long fibers, or a plurality of thin short fibers. A plurality of twists may be used. Further, these strings may be formed in a belt shape.

As a practical and extendable safety cord that achieves the above object, a coiled cord is used as an example.
The coiled string exists in a contracted coil state in a normal free state, and becomes longer and longer in a spiral shape with a long cycle when stretched by applying an external force. As shown in FIG. 1, the string may be made of a plastic material, and may be formed by forming one thick long fiber into a coil shape, or a wire may be attached to the core of the thick long fiber of the plastic for reinforcement. It may be a string that is formed into a coil through it.

In addition, practical stretchable safety cords that achieve the above-mentioned purpose include a string having elasticity through a rubber string through a fiber string, and a spandex fiber inserted into a fiber to increase elasticity. There are various types of strings, such as the ones you have. In short, any stretchable cord that can achieve the first point and the second point can be used. In use, it goes without saying that a string having strength, elongation, and durability sufficient for the purpose is selected. Next, an example of the present invention will be described with reference to an example, but the present invention is not limited to this example.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a string made of a single long fiber of plastic having a diameter of 2 mm and formed into a coil shape was used as a safety cord for a portable telephone. The string withstands the pulling gravity far greater than the gravity of the mobile phone, has a large elongation, and has a durability of several years or more.

A person having an extension of 170 cm, an upper body (= distance from the belt position to the mouth) of 50 cm, and a lower body (= distance from the belt position to the sole) of 96 cm uses the above-mentioned coil when using the mobile phone. Set the upper limit length of the safety cord. That is, a hook provided at one end of the safety cord is connected to the strapping portion of the mobile phone, and the other end is dropped from above by hand while holding the other end, and the length of the spirally elongated cord having a small peak and valley width and a long cycle. The length was measured on a scale, and the length of the strap at which the mobile phone did not land was set to 70 cm in vertical distance from the height of the waist, and a hook at the other end was attached at a location 70 cm above the lower end of the strap. The length of the coiled safety string was 12 cm in a normal free state in which the coiled cord was contracted.

Next, the attachment hook at the other end of the safety cord connected to the mobile phone was connected and fixed to the belt through the pants, and the mobile phone was also stored in the phone case attached to the belt and carried. When not using the mobile phone,
The safety cord shrunk into a coil having a length of 12 cm, and was kept small in the waist, and felt no inconvenience in the movement of the body.

Next, to make a call, the mobile phone was taken out of the phone case containing the mobile phone and brought to the ears and mouth, but the coil-shaped safety cord was immediately extended and the mobile phone was easily moved to the ears and mouth. I was able to hear the story clearly.

It was assumed that the hand slipped and dropped the mobile phone during talking, and the hand was released from the mobile phone. However, before the mobile phone reached the ground, the cord stopped growing and was dropped and damaged. I was able to draw it without any trouble. Needless to say, if there was no safety cord, it hit the ground and was damaged.

[0023]

According to the present invention, it is possible to prevent the portable telephone from being damaged by falling down on the ground by using the safety cord for the portable telephone.
In addition, it was possible to prevent damage to people and objects due to the drop of the mobile phone from a high place, and it became possible to use the mobile phone with confidence. Since the safety cord is stretchable, when the mobile phone is not in use, it stays small in the waist and does not cause any inconvenience to the movement of the body. Furthermore, since the safety cord is always connected and fixed to the lower back of the body, the portable telephone is not left behind.
