Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-fold mobile phone, which is particularly popular in recent years, and more particularly to a two-fold mobile phone housing having an improved upper lid / lower lid fitting structure. .

[0002]

2. Description of the Related Art An ordinary two-fold mobile phone is structurally composed of an upper lid and a lower lid, and is constructed as a mobile phone incorporating a communication electronic circuit capable of communicating by transmitting and receiving radio waves. A display device that is mechanically and electrically detachably attached and has a built-in rechargeable battery that supplies power to the electronic circuit, is provided on the upper lid to display information on a liquid crystal display, and the lower lid. It is roughly configured by a plurality of keys which are applied switches, and an earpiece and a mouthpiece which are provided above the display device and below the plurality of keys, respectively.

In the case of such a conventional two-fold mobile phone, the upper lid and the lower lid have a structure in which the inner surfaces of the both lids are simply superposed and the lids are slid in opposite directions. If it is applied for some reason, the hinge parts of the both lids may be damaged, and since excessive force is applied to the hinge parts, the assembly of the hinge parts may be loose after years of use. There is a structure in which elastic members are provided on the left and right sides of the earpiece, in which protrusions are simply provided on the left and right sides of the mouthpiece, and the protrusions are brought into contact with this, but this structure has both lids. It is provided in order to improve the feeling of closing when closed, and it cannot withstand the sliding force of the two lids in the opposite direction. There is a concern that it will shift.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to incorporate an electronic circuit for communication, which has an antenna extending to the outside, is driven by a battery, and is capable of communicating from the earpiece by transmitting and receiving radio waves, In a case of a two-fold mobile phone having a general mobile phone function having a display device, a plurality of keys, etc., a hole perforated on the left and right of the earpiece of an upper lid having the display device and having an earpiece, The lower lid having a plurality of keys and having a mouthpiece protrudes to the left and right of the mouthpiece, and forms a truncated cone projection that fits into the hole. The present invention provides a case of a two-fold mobile phone, which can be strengthened against the force applied in the opposite direction and thus eliminates the risk of the hinge part being displaced and can be opened and closed without positional displacement of the lid that has been used for a long time.

[0005]

[Means for Solving the Problems] Means for solving the above-mentioned problems of the present invention is for communication that has an antenna extending to the outside, is driven by a battery, and is capable of making a call from an earpiece by transmitting and receiving radio waves. In a housing of a two-fold mobile phone having a general mobile phone function having an electronic circuit and a display device and a plurality of keys and the like, on the left and right of the earpiece of an upper lid having the display device and having an earpiece. A hole formed by punching and a projection of a frusto-conical body that projects to the left and right of the mouthpiece of the lower lid that has the plurality of keys and that has a mouthpiece and that fits into the hole is formed. It is the case of the folded mobile phone.

[0006]

[Function] When the upper lid and the lower lid are closed, the holes provided on the left and right sides of the earpiece guide the protrusions and the protrusions are closely fitted into the holes. Even if force is applied in the opposite direction for some reason, it is inserted into the hole and resists the force urged by the action of both of the protrusions, and no strong force is applied to the hinge parts of both lids. It does not cause looseness. Therefore, the opening and closing of both lids can always be used for a long time at the initially set position.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings, FIG. 1 and FIG. 2. FIG. 1 is a perspective view when a two-fold mobile phone is opened, and FIG. FIG.

Reference numeral 1 is a housing of a two-fold mobile phone which is made of plastic and is bent from the center, and a communication electronic circuit capable of communicating by transmitting and receiving radio waves is incorporated inside. The casing 1 is composed of an upper lid 3 having a liquid crystal device 2 for displaying various data and a lower lid 5 having a plurality of switch function keys 4 for inputting various functions. The key 4
Letters, numbers and pictograms are formed on the surface of the.

Below the key 4, a mouthpiece 6 is formed so that the user can speak. An earpiece 7 is formed on the liquid crystal device 2 so that the earpiece can be received. An external connection terminal 8 is formed on the peripheral edge of the lower lid 5 near the mouthpiece 6. 9 is an antenna. Holes 10 are formed on the left and right sides of the earpiece 7 of the upper lid 3. This hole 10 is a space having a trapezoidal cross section which becomes narrower as it goes deeper, and a projection 11 can be tightly inserted into this hole 10.

That is, as shown in FIG. 1, the projections 11 are formed by implanting them on the left and right sides of the mouthpiece 6 of the lower lid 5, and have a truncated cone shape. Therefore, when the protrusion 11 closes the upper lid 3 and the lower lid 5, the protrusion 11 tightly closes the hole 10.
It becomes a positional relationship to be inserted into. Therefore, the upper lid 3 and the lower lid 5
Since the protrusions 11 are tightly inserted into the holes 10 even if they receive some force in which the and slide in opposite directions, their relative positional relationship does not change. Therefore, the hinge 12 portion of the upper lid 3 and the lower lid 5 The hinge 12 does not loosen with age due to no force applied to it.

In the above example, it is preferable to dispose the protrusions 11 on the left and right sides of the mouthpiece 6 and the holes 10 on the left and right sides of the earpiece 7, but the protrusions 11 are disposed on the left and right sides of the earpiece 7. ,
The holes 10 may be arranged on the left and right of the mouthpiece 6.
In other words, since the earpiece 7 is on the side where the user puts it on his / her ear, there is concern that the projection 11 may hit the ear and cause discomfort.

[0012]

As described above, the present invention has an antenna extending to the outside, is driven by a battery, and is equipped with a communication electronic circuit capable of making a call from a transmitter / receiver by transmitting and receiving radio waves. In a case of a two-fold mobile phone having a general mobile phone function having a plurality of keys and the like, a hole perforated on the left and right of the earpiece of an upper lid having the display device and having an earpiece, and the plurality of keys. The lower lid having the mouthpiece and protruding to the left and right of the mouthpiece, and forming the projection of the frusto-conical body that fits into the hole, the lids in opposite directions for some reason. Therefore, it is possible to provide a housing for a two-fold mobile phone, which can be strengthened against the force applied to it and thus can eliminate the risk of the hinge portion being displaced and can be expected to be opened and closed without the positional displacement of the lid used over the years.
