Description

【０００１】
【発明の属する技術分野】
本発明は主としてデジタルカメラやビデオカメラや携帯電話等の小型の液晶機器用遮光フードに関し、より詳細には、汎用性に富み、着脱自在でかつ安定した状態で固定可能な液晶機器用遮光フード及びその製造方法に関する。
【０００２】
【従来の技術】
近年、カメラ本体の背面部に電子ビューファインダとして使用可能な液晶画面を備えたデジタルカメラが普及してきている。この種のデジタルカメラにおいては、太陽光等の外部からの入射光により、液晶画面に表示された画像が見にくくなることがある。このようなことから、外部からの入射光を遮蔽するために、液晶画面の周囲を覆うように遮光フードを取付けることが考えられている。
従来、このような遮光フードはデジタルカメラの外形状に対応した装着部を形成し、デジタルカメラに係合させて取付けていた。このような遮光フードにおいては、デジタルカメラの機種ごとにその装着部の形状を変更する必要があり、生産コストが高くなる。また、汎用性が低く他のデジタルカメラに用いることができないので、デジタルカメラを買い換える度に遮光フードも買い換えなければならなかった。
【０００３】
このような問題を解決し、デジタルカメラの機種に依存しないようにした遮光フードとしては、実用新案登録第３０７９２５３号の公報に記載されている遮光フードがある。この遮光フードは、デジタルカメラに一対の紐材を捲回張着させ、この両紐材を介して遮光フードを液晶画面に着脱自在に装着して使用するものである。このような構成によれば、遮光フードをデジタルカメラの機種に依存することなく取付け可能である。しかしこの場合、紐材を介することから、デジタルカメラに直接遮光フードを取付ける場合に比べて、遮光フードの取付け状態が不安定であるという問題点がある。
【０００４】
デジタルカメラの機種に依存しないようにした遮光フードとしては、実用新案登録第３０７９７３８号の公報に記載されている遮光フードもある。この遮光フードも機種に依存することなく使用でき、汎用性に富んでいる。また、この遮光フードは一体の硬質紙でできており、組立てて使用し、使用後は畳むことによってフード全体がかさばらず、遮光フードを取付けたままでもデジタルカメラをバッグやデジタルカメラの収納ケース等に収納することが可能である。
【０００５】
【解決しようとする課題】
しかし、この硬質紙でできた遮光フードは、両面接着テープでデジタルカメラに取付ける構成となっており、両面接着テープによって遮光フードを取付けたままにしておくと、デジタルカメラに両面接着テープによるベタつきが発生する。また、何度か着脱を繰返すと両面接着テープの粘着力が落ちてくる。
【０００６】
本発明は以上のような点を鑑みてなされたものであり、汎用性に富み、着脱自在でかつ安定した状態で固定可能であり、さらに両面接着テープ等を用いることなくデジタルカメラを汚すことのないデジタルカメラ用遮光フード及びその製造方法を提供することを目的とする。
【０００７】
更に本発明は、上記デジタルカメラと共に、液晶機器が、ビデオカメラ、携帯電話、ＰＨＳ、携帯ゲーム機、携帯テレビ、車両用ナビゲーター、及び携帯情報端末機等からなるものについても、同一の目的を達成する液晶機器用遮光フード及びその製造方法を提供することを目的とする。

【００１８】
【発明の実施の形態】
以下、本発明の第一の実施形態における液晶機器がデジタルカメラである場合について、そのデジタルカメラ用遮光フード及びその製造方法を、添付図面を参照しつつ説明する。
図１は本発明の第一の実施形態におけるデジタルカメラ用遮光フードの斜視図、図２は本発明の第一の実施形態における装着体の正面図、図３は図２におけるＢ−Ｂ断面図、図４は図３におけるＣ−Ｃ断面図、図５は本発明の第一の実施形態における遮光体の正面図、図６は図５におけるＤ−Ｄ断面図、図７は図１におけるＡ−Ａ断面図、図８は本発明の第一の実施形態におけるデジタルカメラ用遮光フードのデジタルカメラへの装着状態を示す斜視図、図９は本発明の第２の実施形態におけるデジタルカメラ用遮光フードの断面図である。
【００１９】
まず、第一の実施形態における液晶機器がデジタルカメラである場合の遮光フードについて説明する。フード本体１は図１に示すように、略方形の筒状からなり、デジタルカメラＰの液晶画面Ｑの周囲に着脱自在に取付ける装着体１０と、装着体１０の先方部側（デジタルカメラを向く面の反対側を指すものとする）に着脱自在に装着する遮光体２０から構成される。
フード本体１をデジタルカメラＰに取付けた際、フード本体１の内側の貫通部２を通じて液晶画面Ｑに表示された画像を見るが、ここで、流通しているデジタルカメラの液晶画面は１．８インチ程度のものが一般的であるので、本実施形態では貫通部２の方形の大きさは１．８インチよりも多少大きい２インチ程度のものとする。もちろん、方形の大きさはこれに限られるものではなく、流通するデジタルカメラの液晶画面の大きさに合うように変更可能である。
【００２０】
装着体１０は図２に示すように、略方形の筒状からなると共に、外筒１１及び内筒１２を有し、これらの間には略筒状の空洞部１３が設けてある。外筒１１と内筒１２は、図３、図４に示すように、空洞部１３に設けたリブ片１６、１６によって連結されている。本実施形態では図４に示すように、４つのリブ片１６、１６によって外筒１１と内筒１２を連結する構造としているが、リブ片１６の数はこれに限らず、必要に応じて増減してよい。また、リブ片１６を設ける場所も図４に示すよう上下左右の中間位置に限られるものではなく、他の場所に設けるような構造としてもよい。
【００２１】
外筒１１と内筒１２の間に設けた筒状の空洞部１３の全体に、粘着性の軟質材からなる接着体たるプラスティックゲル１４が、リブ片１６、１６を包み込むように一体的に取付けられている。このプラスティックゲル１４を用いれば、両面接着テープを使用して遮光フードをデジタルカメラに着脱した際に生じるような接着面のベタつきが生じない。また、プラスティックゲル１４の接着表面に付着した埃、ゴミ等を洗浄することによって粘着力を回復・保持することができる。なお、ここではプラスティックゲルを用いることとしたが、同様の効果を有する軟質材からなる接着体であれば利用可能である。
【００２２】
また、筒状の空洞部１３に取付けたプラスティックゲル１４は、基部側（デジタルカメラを向く側を指すものとする）の面から突出させた膨出部１４ａが形成されている。この膨出部１４ａを液晶画面Ｑの外縁部に接着することにより装着体１０をデジタルカメラＰに取付ける。
ここで、本実施形態では空洞部１３は基部側の面から先方部側の面まで貫通し、この空洞部１３全体にプラスティックゲル１４を取付ける構成となっているが、空洞部１３を貫通するようにはせず、基部側の面にのみ空洞部１３を設け、ここにプラスティックゲル１４を取付ける構成としてもよい。
【００２３】
装着体１０の外周部１５には、先方部側に凸部１５ａが形成されている。この凸部１５ａは後述する遮光体２０に形成した凹部２１ａと係合し、遮光体２０の装着体１０に対する挿入方向の位置を固定すると共に、装着状態を維持する役割を果たす。
また、装着体１０の外周部１５には、基部側に凸状の当接部１５ｂが形成されている。この当接部１５ｂは、遮光体２０を装着体１０に装着する際に、遮光体２０の基部側の面と当接し、遮光体２０の装着体１０に対する挿入方向の位置を固定する役割を果たす。
ここで、凸部１５ａと凹部２１ａの係合と、当接部１５ｂと遮光体２０の基部側の面との当接はほぼ同時であり、どちらも遮光体２０を装着体１０に対して同位置に固定するように形成されている。
【００２４】
遮光体２０は図５に示すように、略方形の筒状からなると共に、基部を垂直面状に、先方部を斜面状に形成してなる。すなわち、上面２０ａは長尺に、下面２０ｂは短尺に形成されている。このように形成することにより、外部からの入射光、特に太陽光などの上方からの光を十分に遮蔽することができる。もちろん、それ以外の側方等からの光も十分に遮蔽可能である。
【００２５】
遮光体２０は、図６に示すように、その基部側を連接部２１としている。連接部２１は遮光体１０の外周部１５と重合し、遮光体２０が装着体１０にガタつきなく装着されるようにする役割を果たす。また、連接部２１には凹部２１ａが形成されており、上述した装着体１０の凸部１５ａと係合して、遮光体２０の装着体１０に対する挿入方向の位置を固定すると共に、装着状態を維持する役割を果たす。ここで、本実施形態では、装着体２０に凸部を、遮光体１０に凹部を形成することとしたが、凹凸を逆にしても同様の効果が得られる。
【００２６】
遮光体２０を装着体１０に装着して使用する際には、遮光体２０の内側の通視部２２から液晶画面Ｑを覗くこととなる。この通視部２２にはその内側の四周にストッパー部２３が連続して設けられている。このストッパー部２３は、遮光体２０を装着体１０に装着する際に、装着体１０の先方部側の面と当接して、遮光体２０の装着体１０に対する挿入方向の位置を固定する役割を果たす。
ここで、ストッパー部２３と装着体１０の先方部側の面との当接と、当接部１５ｂと遮光体２０の基部側の面との当接もほぼ同時であり、どちらも遮光体２０を装着体１０に対して同位置に固定するように形成されている。
このストッパー部２３は連続して設けるものに限られることなく、部分的に設けるような形態でもよい。また、凸部１５ａと凹部２１ａをもって、遮光体２０の位置の固定が十分になされていれば、ストッパー部２３を設けないことも可能である。
【００２７】
次に、フード本体１のデジタルカメラＰへの取付け方法について、図７，図８に基づいて説明する。まず、遮光体２０を装着体１０に装着する。具体的には、遮光体２０の連接部２１と、装着体１０の外周部１５を重合させながら遮光体２０を装着体１０に挿入していき、遮光体２０のストッパー部２３が装着体１０の先方部側の面に当接すると共に、遮光体２０の基部側の面が装着体１０の外周部１５の当接部１５ｂに当接するまで遮光体２０を装着体１０に押込む。またこのとき、遮光体２０の連接部２１に形成した凹部２１ａと、装着体１０の凸部１５ａが係合し、遮光体２０を装着体１０に装着した状態が維持される。
【００２８】
次に、図８に示すように、遮光体２０を装着した装着体１０をデジタルカメラＰに取付ける手順を説明する。具体的には、液晶画面Ｑの外縁部に装着体１０のプラスティックゲル１４を当接させて少し押込むことによって、該プラスティックゲル１４の膨出部１４ａが液晶画面Ｑの外縁部に接着し、これによって装着体１０をデジタルカメラＰに取付ける。このプラスティックゲル１４は取付け状態を維持する程度に強固な粘着力を有するが、人の力によって簡単にデジタルカメラＰから取外すことができる。
【００２９】
なおここでは、まず遮光体２０を装着体１０に装着し、その後デジタルカメラＰに取付ける場合について示したが、他の方法、すなわち、まず装着体１０をデジタルカメラＰに取付け、その後遮光体２０を装着体１０に装着することももちろん可能である。
また、デジタルカメラＰからフード本体１を取外す際も、遮光体２０を装着体１０に装着したまま取外すこともできるし、遮光体２０だけを取外すことも可能である。遮光体２０だけを取外せば、装着体１０を取付けた状態でもバッグやデジタルカメラの収納ケース等に収納することは十分可能である。
【００３０】
次に、本実施形態におけるデジタルカメラ用遮光フードの製造方法について説明する。まず、装着体１０の製造について説明する。装着体１０は略方形の筒状に形成されると共に、外筒１１及び内筒１２を有し、これらの間には略筒状の空洞部１３が設けられている。また、外筒１１と内筒１２は４つのリブ片１６、１６によって連結されている。これらを全て、装着体成形用金型によってプラスティック等の熱可塑性樹脂を用いて一体成形する。
【００３１】
一体成形した外筒１１及び内筒１２を有する装着体１０を、装着体成形用金型から取り出し、装着体１０の略筒状の空洞部１３の略全体にプラスティックゲル１４を充填し、プラスティックゲル１４を装着体１０と一体的となるように取付ける。プラスティックゲル１４は、充填時はその温度が高いため流動性に富んでいるが、充填後冷却することにより流動性を失い固化する。また、プラスティックゲル１４が装着体１０の基部側の面から略筒状に突出した膨出部１４ａを有するように、プラスティックゲル１４を充填・形成する。
【００３２】
次に、遮光体２０の製造について説明する。遮光体２０は略方形の筒状に形成されると共に、基部を垂直面状に、先方部を斜面状に形成し、かつ、基部側を連接部２１としている。これらも全て、遮光体成形用金型によってプラスティック等の熱可塑性樹脂を用いて一体成形する。このようにして製造した装着体１０に遮光体２０を装着して、フード本体１を形成する。
【００３３】
以上、上記第一の実施形態では、装着体１０と遮光体２０を別々に形成し、装着体１０に遮光体２０を装着してフード本体１を形成する構成とした。しかし、他の構成をとることも可能である。
【００３４】
以下、図９に示すように、第二の実施形態におけるデジタルカメラ用遮光フードについて説明する。
第二の実施形態におけるデジタルカメラ用遮光フードは、概略構成は第一の実施形態と同様であり、フード本体１は略方形の筒状からなり、装着体１０と遮光体２０から構成される。
装着体１０は略方形の筒状からなると共に、外筒１１及び内筒１２を有し、これらの間には略筒状の空洞部１３が設けてある。外筒１１と内筒１２は連通部１７によって四周にわたって連続的に連結されている。外筒１１と内筒１２の間に設けた筒状の空洞部１３の全体に、プラスティックゲル１４が一体的に取付けられている。このプラスティックゲル１４は、基部側の面から突出させた膨出部１４ａが形成されている。また、遮光体２０は略方形の筒状からなると共に先方部を斜面状に形成してなる。
【００３５】
ここで、本実施形態では装着体１０と遮光体２０は一体的に形成される。すなわち、装着体１０の外筒１１の先方部側から遮光体２０が連続的に形成されている。これによりフード本体１の構成が簡略化される。
【００３６】
次に、図１０に示すように、液晶機器がビデオカメラである場合の第三の実施形態について説明する。
遮光体２０を装着した装着体１０をビデオカメラＲに取付ける手順を説明する。具体的には、ビデオカメラＲの液晶画面Ｑを開放状態にして、この液晶画面Ｑの外縁部に装着体１０のプラスティックゲル１４を当接させて少し押込むことによって、該プラスティックゲル１４の膨出部１４ａが液晶画面Ｑの外縁部に接着し、これによって装着体１０をビデオカメラＲに取付ける。
【００３７】
次に、図１１に示すように、液晶機器が携帯電話である場合の第三の実施形態について説明する。
遮光体２０を装着した装着体１０を携帯電話Ｓに取付ける手順を説明する。具体的には、折り畳み式の携帯電話Ｓの液晶画面Ｑを開放状態にして、この液晶画面Ｑの外縁部に装着体１０のプラスティックゲル１４を当接させて少し押込むことによって、該プラスティックゲル１４の膨出部１４ａが液晶画面Ｑの外縁部に接着し、これによって装着体１０を携帯電話Ｓに取付ける。
なお、携帯電話Ｓは、折り畳み式に限らず、非折り畳み式の開放型であってもよく、また、ＰＨＳを含むものである。
【００３８】
次に、図１２に示すように、液晶機器が携帯ゲーム機である場合の第三の実施形態について説明する。
遮光体２０を装着した装着体１０を携帯ゲーム機Ｔに取付ける手順を説明する。具体的には、携帯ゲーム機Ｔの液晶画面Ｑの外縁部に装着体１０のプラスティックゲル１４を当接させて少し押込むことによって、該プラスティックゲル１４の膨出部１４ａが液晶画面Ｑの外縁部に接着し、これによって装着体１０を携帯ゲーム機Ｔに取付ける。
なお、上記携帯ゲーム機Ｔと同様な形態を有する、携帯情報端末機や、携帯液晶テレビや、車両用ナビゲーター等にも、本発明の遮光フードが取付けられる。また、上記したビデオカメラＲ等の各実施形態のものも、第一実施形態と同様に、装着体１０には、空洞部１３が形成され、該空洞部１３にプラスティックゲル１４が取付けられ、該プラスティックゲル１４には膨出部１４ａが形成されている。
【００３９】
更に本発明は、上記デジタルカメラと共に、液晶機器が、上記したように、ビデオカメラ、携帯電話、ＰＨＳ、携帯ゲーム機、携帯テレビ、車両用ナビゲーター、及び携帯情報端末機等からなるものについても、同一の目的を達成する液晶機器用遮光フード及びその製造方法を提供することができるものであり、また、図９に示したように、装着体１０と遮光体２０を一体的に形成したものを、これらに使用することもできる。
【００４０】

【００４５】
また、本発明に係る液晶機器用遮光フードによれば、接着体を空洞部に設けたリブ片を包み込むように空洞部の全体に一体的に取付けるので、装着体はリブ片の周囲にも接着体を有し、装着体を液晶機器に対しより強固に取付けることができる。

【００４７】
また、本発明に係る液晶機器用遮光フードによれば、遮光体の内面に凸状のストッパー部を設け、及び／又は装着体の外周部の基部側に凸状の当接部を設けるので、遮光体を装着体に装着する際に遮光体の装着体に対する挿入方向の位置を固定され、遮光体の装着体への装着をより安定したものにすることができる。
【００４８】
また、本発明に係る液晶機器用遮光フードによれば、液晶機器に取付ける装着体と遮光体を一体的に形成してフード本体を構成したので、フード本体の構成を簡略化することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light-shielding hood for a small liquid crystal device such as a digital camera, a video camera, and a mobile phone, and more particularly to a light-shielding hood for a liquid crystal device which is rich in versatility, is detachable, and can be fixed in a stable state. It relates to the manufacturing method.
[0002]
[Prior art]
2. Description of the Related Art In recent years, digital cameras having a liquid crystal screen that can be used as an electronic viewfinder on the back of a camera body have become widespread. In this type of digital camera, an image displayed on a liquid crystal screen may be difficult to see due to external incident light such as sunlight. For this reason, it has been considered to attach a light-shielding hood so as to cover the periphery of the liquid crystal screen in order to shield external incident light.
Conventionally, such a light-shielding hood forms a mounting portion corresponding to the outer shape of the digital camera, and is mounted in engagement with the digital camera. In such a light-shielding hood, it is necessary to change the shape of the mounting portion for each type of digital camera, which increases the production cost. Further, since the versatility is low and the digital camera cannot be used for other digital cameras, the light-shielding hood has to be replaced every time the digital camera is replaced.
[0003]
As a light-shielding hood that solves such a problem and does not depend on the type of digital camera, there is a light-shielding hood described in Japanese Utility Model Registration No. 3079253. This light-shielding hood is used by winding a pair of strings on a digital camera, and detachably attaching the light-shielding hood to the liquid crystal screen via the two strings. According to such a configuration, the light shielding hood can be attached without depending on the model of the digital camera. However, in this case, there is a problem in that the mounting state of the light-shielding hood is unstable compared to a case where the light-shielding hood is directly attached to the digital camera because of the interposition of the cord material.
[0004]
As a light-shielding hood that does not depend on the type of digital camera, there is also a light-shielding hood described in Japanese Utility Model Registration No. 3079738. This shading hood can also be used without depending on the model, and is versatile. In addition, this shading hood is made of one piece of rigid paper, and it is assembled and used, and after use, the whole hood is not bulky by folding, so even if the shading hood is attached, the digital camera can be stored in a bag or a digital camera storage case, etc. It is possible to store in.
[0005]
[Problem to be solved]
However, the light-shielding hood made of this hard paper is configured to be attached to the digital camera with double-sided adhesive tape, and if the light-shielding hood is left attached with double-sided adhesive tape, the digital camera will become sticky with double-sided adhesive tape. appear. Further, if the attachment and detachment are repeated several times, the adhesive strength of the double-sided adhesive tape decreases.
[0006]
The present invention has been made in view of the above points, is versatile, is detachable and can be fixed in a stable state, and further stains a digital camera without using a double-sided adhesive tape. It is an object to provide a shading hood for a digital camera and a manufacturing method thereof.
