Description

【0001】
【発明の属する技術分野】
本発明は、ディスプレイを具えた第1キャビネットと、操作釦を具えた第2キャビネットをヒンジ接続し、折畳み可能な携帯電話機に関する。
【0002】
【従来の技術】
図3は、従来の携帯電話機の側面図である。携帯電話機は、ディスプレイ(10)を具えた第1キャビネット(1)と、操作釦(20)を具えた第2キャビネット(2)をヒンジ部(4)で接続している。図3に実線で示すように、両キャビネット(1)(2)が開いた開位置と、図3に点線で示すように両キャビネット(1)(2)が閉じた閉位置との間を回動自在に設けられる。携帯電話機は、閉位置にて携帯され、通話時に開位置に開かれる。
第2キャビネット(2)には、開位置の第1キャビネット(1)に接するストッパ(5)が設けられ、該ストッパ(5)は両キャビネット(1)(2)が通話時に開位置よりも開くことを規制している。尚、ストッパ(5)はキャビネット(1)(2)の何れに設けられてもよい。第1キャビネット(1)の先端部には、小筒体(31)及び該小筒体(31)から出没するアンテナ(30)が設けられ、以下の記載では小筒体(31)とアンテナ(30)をアンテナ部(3)と称する。
図4は、図3の平面図である。第2キャビネット(2)の端部には、凹部(21)及び該凹部(21)の両側に位置する突片(22)(22)が形成されている。両キャビネット(1)(2)のヒンジ部(4)は、第1キャビネット(1)の端部に設けられた突部(11)を、第2キャビネット(2)の凹部(21)に嵌め、突片(22)(22)の外側から枢軸(40)(40)を突片(22)(22)及び突部(11)に挿入して形成される。
【0003】
【発明が解決しようとする課題】
図3に示すように、開位置にて机上又は床面に置かれた携帯電話機に対し、使用者の不注意により、第1キャビネット(1)の先端部の上から荷重を不用意に加えることがある。第1キャビネット(1)はストッパ(5)に接した位置から更に開く向きに撓む。
この場合、第1キャビネット(1)にはストッパ(5)を支点として時計方向に回転する向きの力が加わり、突部(11)が外向きに引っ張られる。突部(11)に嵌まった枢軸(40)が引っ張られ、第2キャビネット(2)の突片(22)(22)は図4に一点鎖線で示すように側方に撓む。この結果、ヒンジ部(4)が破損し、両キャビネット(1)(2)が正確に回動しなくなる虞れがある。
携帯電話機には、図6に示すように、第2キャビネット(2)からアンテナ部(3)を突出し、第2キャビネット(2)の底面から、ヒンジ部(4)までの高さeが高いものがある。又、図7に示すように、ヒンジ部(4)を幅狭に設け、第2キャビネット(2)に設けたアンテナ部(3)を、第2キャビネット(2)の側面とヒンジ部(4)との間の空間内に配置したものもある。このような携帯電話機に於いても、開位置にて第1キャビネット(1)の上から荷重を不用意に加えることにより、ヒンジ部(4)が破損する虞れがある。特に、図5に示すように、両キャビネット(1)(2)を傾けて配備し、ヒンジ部(4)の下側が解放された状態にて、両キャビネット(1)(2)を開く向きの荷重が上から加わると、ヒンジ部(4)が破損し易い。
本発明の目的は、開位置にある両キャビネットを更に開く向きの荷重が、両キャビネットに不用意に加わっても、ヒンジ部が破損することを防止することにある。即ち、突片(22)(22)が破損する前に、第1キャビネット(1)がアンテナ部(3)に当たるような高さe(図6参照)にすることが本発明である。
【0004】
【課題を解決する為の手段】
携帯電話機は、ディスプレイ(10)を具えた第1キャビネット(1)と、操作釦(20)を具えた第2キャビネット(2)をヒンジ部(4)で接続し、第2キャビネット ( ) には第1キャビネット ( ) が開位置よりも開くことを規制するストッパ ( ) が設けられている。第2キャビネット ( ) にはアンテナ部 ( ) が設けられて、該アンテナ部 ( ) は開位置よりも更に開く向きに撓んだ第1キャビネット ( ) を受ける。
【0005】
【作用及び効果】
開位置にある両キャビネット(1)(2)を更に開くような荷重が、キャビネット(1)(2)に不用意に加わると、第1キャビネット(1)は開位置から開く向きに撓む。然るに、撓んだ第1キャビネット(1)はアンテナ部(3)に受けられ、それ以上撓み変形しない。これにより、両キャビネット(1)(2)のヒンジ部(4)に過大な負荷は加わらず、ヒンジ部(4)が破損することを防止できる。
【0006】
【発明の実施の形態】
以下、本発明の一例を図を用いて詳述する。
図1は、開位置にある携帯電話機の斜視図である。従来と同様に、携帯電話機は、通話状態等を表示するディスプレイ(10)を具えた第1キャビネット(1)と、操作釦(20)を具えた第2キャビネット(2)とをヒンジ部(4)で接続し、開位置と閉位置との間を回動する。第2キャビネット(2)の底部からは、第1キャビネット(1)に向けてアンテナ部(3)が突出している。第1キャビネット(1)は、アンテナ部(3)に被さる。
図2は、開位置にある携帯電話機の側面図であり、第2キャビネット(2)を机上又は床面に置いている。開位置にて第1キャビネット(1)は第2キャビネット(2)から延びたストッパ(5)に接しており、アンテナ部(3)とは僅かに離れている。
【0007】
開位置にある両キャビネット(1)(2)を更に開くような荷重が、第1キャビネット(1)に不用意に加わる、具体的には不注意により、第1キャビネット(1)を手で押さえる、又は足で踏むことがある。第1キャビネット(1)は開位置から開く向き、即ち時計方向に撓む。然るに、撓んだ第1キャビネット(1)はアンテナ部(3)に受けられ、それ以上撓み変形できない。これにより、荷重が不用意に加わっても、両キャビネット(1)(2)のヒンジ部(4)に過大な負荷は加わらず、ヒンジ部(4)が破損することを防止できる。
【0008】
ヒンジ部(4)が破損して、両キャビネット(1)(2)が正しく開閉しないと、以下の不都合が生じる。両キャビネット(1)(2)は通話のときは開位置に保持され、終話、即ち通話を終えたとき及び通話をしないときは、閉位置に保持されていなければならない。然るに、ヒンジ部(4)が破損していると、両キャビネット(1)(2)の開閉動作が正確でないから、開位置又は閉位置に正しく達せず、両キャビネット(1)(2)が中途半端な位置に配備される虞れがある。
【0009】
更に、斯種携帯電話機には、通話信号受信時に両キャビネット(1)(2)を開位置にすると、自動的に通話可能状態となり、閉位置に戻すと、自動的に通話が遮断される終話状態となるものがある。然るに、両キャビネット(1)(2)の開閉動作が正確でないと、通話と通話遮断が正確に切り換わらない虞れもあり、使用者に対し、不快感を与える。
また、携帯電話機は閉位置にてポケット又は鞄の中に収納されて携帯されることが多い。両キャビネット(1)(2)が閉位置に正確に戻らないと、キャビネット(1)(2)が稍開いてポケット又は鞄の中の他の部品に引掛かり、キャビネット(1)(2)が歪み又は捻れる。この結果、両キャビネット(1)(2)内の電子部品を破損させる虞れがある。上記の理由から、アンテナ部(3)にて第1キャビネット(1)を受け、ヒンジ部(4)の破損を防ぎ、両キャビネット(1)(2)を正確に開閉させている。
【0010】
出願人は、本例に係わる図2に示す携帯電話機と、従来の図7に示す携帯電話機を、図5に示すように、ヒンジ部(4)の下方を解放した状態で配置した。両キャビネット(1)(2)が開く向きの荷重を上から加え、ヒンジ部(4)が破損する際の荷重を測定した。両キャビネット(1)(2)は、本例及び従来の携帯電話機ともに、PC(ポリカーボネート)とABSのアロイ材から形成され、外形寸法は殆ど同じである。
その結果は、本例の携帯電話機ではヒンジ部(4)が破損する荷重が約40〜100Kgであったのに対し、従来の携帯電話機では該荷重が約10〜20Kgであり、本例の構造がヒンジ部(4)の破損防止に効果があることが判った。
【0011】
尚、携帯電話には図8に示すように、フリップタイプと呼ばれるものがあり、これは1つのキャビネット(2)上にディスプレイ(10)と操作釦(20)を設け、キャビネット(2)の端部に操作釦(20)を覆う蓋体(9)をヒンジ部(4)で接続している。
出願人はこのようなフリップタイプの携帯電話機にあっては、蓋体(9)のヒンジ部(4)の破損を防ぐために、本例のようにアンテナ部(3)をヒンジ部(4)に近傍に配備する必要はないと考えている。本例にあっては、前記の如く、両キャビネット(1)(2)内の電子部品を破損させる虞れを防ぐことを目的としているが、蓋体(9)内には電子部品がないこと、キャビネット(2)には蓋体(9)の開位置を定めるストッパ(5)がなく、蓋体(9)は開ききった状態から、更に開く向きに簡単に撓むから、ヒンジ部(4)を手厚く保護する必要に乏しいとの理由による。
【0012】
図2に示すように、第1キャビネット(1)とアンテナ部(3)は先端に向かって互いに広がる向きに配備されている。第1キャビネット(1)とアンテナ部(3)の成す角度θは、約20度である。図2にあっては、第2キャビネット(2)の底面とアンテナ部(3)が同一面内に配備されているが、アンテナ部(3)が第2キャビネット(2)の底面に対し10度傾けば、角度θは約30度である。
これにより、アンテナ部(3)からアンテナを延ばした際に、第1キャビネット(1)との距離をできるだけ長く設け、アンテナ部(3)の周辺を解放することができる。これにより、アンテナ部(3)が第1キャビネット(1)内の電子部品からノイズ等の影響を受けることを防止でき、アンテナ性能を向上できる。
また、第1キャビネット(1)の先端部には、受信器(図示せず)が内蔵され、使用者は開位置にて耳を受信器に当てる。近年、アンテナ部(3)から発生する高周波が人体に与える影響が懸念されているが、アンテナ部(3)と第1キャビネット(1)との距離をできるだけ長く設けることにより、使用者の頭部とアンテナ部(3)を離し、人体に与える影響を緩和できる。
【0013】
上記実施例の説明は、本発明を説明するためのものであって、特許請求の範囲に記載の発明を限定し、或は範囲を減縮する様に解すべきではない。又、本発明の各部構成は上記実施例に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能であることは勿論である。

[Problems to be solved by the invention]
As shown in FIG. 3, a load is inadvertently applied from the top of the first cabinet (1) to the mobile phone placed on the desk or floor in the open position by the carelessness of the user. There is. The first cabinet (1) bends in the direction of further opening from the position in contact with the stopper (5).
In this case, a force is applied to the first cabinet (1) in the clockwise direction with the stopper (5) as a fulcrum, and the protrusion (11) is pulled outward. The pivot (40) fitted to the protrusion (11) is pulled, and the protrusions (22) and (22) of the second cabinet (2) bend laterally as shown by the one-dot chain line in FIG. As a result, the hinge portion (4) is damaged, and there is a possibility that both the cabinets (1) and (2) will not be rotated accurately.

Moreover, as shown in FIG. 7, the hinge part (4) is provided narrowly, and the antenna part (3) provided in the second cabinet (2) is connected to the side surface of the second cabinet (2) and the hinge part (4). Some are arranged in the space between. Even in such a cellular phone, there is a possibility that the hinge portion (4) may be damaged by inadvertently applying a load from above the first cabinet (1) in the open position. In particular, as shown in FIG. 5, both cabinets (1) and (2) are inclined and arranged so that both cabinets (1) and (2) are opened with the lower side of the hinge part (4) released. When a load is applied from above, the hinge portion (4) is easily damaged.
An object of the present invention is to prevent the hinge portion from being damaged even if a load in a direction to further open both cabinets in the open position is inadvertently applied to both cabinets. That is, it is the present invention that the height e (see FIG. 6) is such that the first cabinet (1) hits the antenna section (3) before the projecting pieces (22) and (22) are damaged.
[0004]
[Means for solving the problems]
The mobile phone is connected to the second cabinet ( 2 ) by connecting the first cabinet (1) having the display (10) and the second cabinet (2) having the operation button (20) by the hinge part (4).

The second cabinet (2) with the antenna section (3) is provided, the antenna unit (3) receives a first cabinet (1) flexed more open orientation than the open position.
[0005]
[Action and effect]
When a load that further opens both the cabinets (1) and (2) in the open position is inadvertently applied to the cabinets (1) and (2), the first cabinet (1) bends in the opening direction from the open position. However, the bent first cabinet (1) is received by the antenna portion (3) and is not further bent and deformed. Thereby, excessive load is not added to the hinge part (4) of both cabinets (1) (2), but it can prevent that a hinge part (4) breaks.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a mobile phone in an open position. As in the prior art, the mobile phone includes a first cabinet (1) having a display (10) for displaying a call state and the like, and a second cabinet (2) having an operation button (20). ) And rotate between the open position and the closed position. From the bottom of the second cabinet (2), the antenna part (3) protrudes toward the first cabinet (1). The first cabinet (1) covers the antenna part (3).
FIG. 2 is a side view of the mobile phone in the open position, in which the second cabinet (2) is placed on the desk or floor. In the open position, the first cabinet (1) is in contact with a stopper (5) extending from the second cabinet (2) and is slightly separated from the antenna part (3).
[0007]
A load that further opens both cabinets (1) and (2) in the open position is inadvertently applied to the first cabinet (1). Specifically, the first cabinet (1) is pressed by hand inadvertently. Or you may step on your feet. The first cabinet (1) bends from the open position to open, that is, clockwise. However, the bent first cabinet (1) is received by the antenna portion (3) and cannot be bent and deformed any further. Thereby, even if a load is applied carelessly, an excessive load is not applied to the hinge portions (4) of both cabinets (1) and (2), and the hinge portions (4) can be prevented from being damaged.
[0008]
If the hinge part (4) is damaged and the cabinets (1) and (2) do not open and close correctly, the following inconvenience occurs. Both cabinets (1) and (2) must be held in the open position during a call, and must be held in a closed position when the call is finished, ie when the call is finished and when no call is made. However, if the hinge part (4) is damaged, the open / close operation of both cabinets (1) and (2) is not accurate, so the open position or the closed position cannot be reached correctly, and both cabinets (1) and (2) are halfway There is a risk of being deployed in an odd position.
[0009]
Further, in such a cellular phone, when both cabinets (1) and (2) are set to the open position when a call signal is received, the call is automatically made possible. When the cabinet is returned to the closed position, the call is automatically cut off. There is something that goes into talk. However, if the opening / closing operations of both cabinets (1) and (2) are not accurate, there is a possibility that the call and the call blocking may not be switched accurately, which causes discomfort to the user.
In addition, mobile phones are often carried in a closed position in a pocket or bag. If both cabinets (1) and (2) do not return correctly to the closed position, the cabinet (1) and (2) will open and catch on other parts in the pocket or bag and the cabinet (1) and (2) will Strain or twist. As a result, the electronic components in both cabinets (1) and (2) may be damaged. For the above reason, the antenna section (3) receives the first cabinet (1), prevents the hinge section (4) from being damaged, and opens and closes both cabinets (1) and (2) accurately.
[0010]
The applicant arranged the cellular phone shown in FIG. 2 according to this example and the conventional cellular phone shown in FIG. 7 with the lower part of the hinge part (4) opened as shown in FIG. A load in the direction in which both cabinets (1) and (2) open was applied from above, and the load when the hinge part (4) was damaged was measured. Both cabinets (1) and (2) are formed of an alloy material of PC (polycarbonate) and ABS in both the present example and the conventional mobile phone, and the outer dimensions are almost the same.
As a result, the load for damaging the hinge portion (4) was about 40-100 kg in the mobile phone of this example, whereas the load was about 10-20 kg in the conventional mobile phone. Was found to be effective in preventing damage to the hinge portion (4).
[0011]
As shown in FIG. 8, there is a mobile phone called a flip type, in which a display (10) and operation buttons (20) are provided on one cabinet (2), and the end of the cabinet (2) is provided. A lid (9) covering the operation button (20) is connected to the part by a hinge part (4).
In such a flip-type mobile phone, the applicant applies the antenna portion (3) to the hinge portion (4) as in this example in order to prevent damage to the hinge portion (4) of the lid (9). I do not think it is necessary to deploy in the vicinity. The purpose of this example is to prevent the possibility of damaging the electronic components in both cabinets (1) and (2) as described above, but there are no electronic components in the lid (9). The cabinet (2) does not have a stopper (5) for determining the opening position of the lid (9), and the lid (9) is easily bent from the fully opened state to the opened direction. ) Because of the lack of need for extensive protection.
[0012]
As shown in FIG. 2, the first cabinet (1) and the antenna section (3) are arranged in a direction that spreads toward the tip. The angle θ formed by the first cabinet (1) and the antenna unit (3) is about 20 degrees. In FIG. 2, the bottom surface of the second cabinet (2) and the antenna portion (3) are arranged in the same plane, but the antenna portion (3) is 10 degrees with respect to the bottom surface of the second cabinet (2). If tilted, the angle θ is about 30 degrees.
Thereby, when extending an antenna from an antenna part (3), distance with the 1st cabinet (1) can be provided as long as possible, and the circumference of antenna part (3) can be released. Thereby, it can prevent that an antenna part (3) receives the influence of a noise etc. from the electronic component in a 1st cabinet (1), and can improve antenna performance.
In addition, a receiver (not shown) is built in the tip of the first cabinet (1), and the user puts his / her ear on the receiver in the open position. In recent years, there is a concern about the influence of the high frequency generated from the antenna unit (3) on the human body, but by providing the distance between the antenna unit (3) and the first cabinet (1) as long as possible, And the antenna part (3) can be separated to reduce the influence on the human body.
