Description

【０００１】
【発明の属する技術分野】
本発明は、ドーム型カメラのカバー、ドーム型カメラ及びその組立方法に関する。
【０００２】
【従来の技術】
建造物の天井や壁等に取り付けるドーム型カメラは、撮影を行うためのカメラユニット、内部カバー部及び外部カバー部を有している。内部カバー部は、一部に切り欠き部を有しており、通常この切り欠き部を通して撮影が行われる。
内部カバー部、外部カバー部及びカメラユニットを別々に設置するドーム型カメラでは、カメラ設置時に以下のように組み立てられる。まず、カメラユニットを天井に取り付ける。さらに内部カバー部をカメラユニットを覆うように取り付け、次に内部カバー部を覆うように外部カバー部をカメラユニットに取り付ける。
【０００３】
一方、内部カバー部と外部カバー部とが係合し固定されたドーム型カメラでは、内部カバー部が外部カバー部の内部に沿うように固定されたカバー部を、カメラユニットを覆うように取り付ける。
【０００４】
【発明が解決しようとする課題】
しかし、内部カバー部、外部カバー部及びカメラユニットを別々に設置するドーム型カメラにおいては、カメラユニットを設置した後、内部カバー部及び外部カバー部を別々に取り付ける必要があるため設置に手間がかかる。天井や壁などに設置するドーム型カメラの設置作業は地上での設置と比較して困難であるため、特に手間を要する。
また、内部カバー部と外部カバー部とが係合し固定されたドーム型カメラにおいても、外部カバー部をカメラユニットに対して移動させた場合、同時に切り欠き部を有する内部カバー部も移動する。よって、カメラ撮影を行うための切り欠き部の方向とカメラ方向とが一致しなくなり、カメラの撮影が妨害されてしまう場合が生じ得る。
【０００５】
そこで、本発明は、組み立てが容易なカバーユニットを提供することを目的とする。
また、本発明は、設置作業が容易なドーム型カメラのカバーを提供することを目的とする。
また、本発明は、カメラ撮影が妨害されないドーム型カメラのカバーを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記の課題を解決するために、本願第１発明は、機能ユニットを覆うカバーユニットであって、前記機能ユニットを覆う外部カバー部と、前記外部カバー部の内側に沿うように設けられた内部カバー部と、前記外部カバー部及び前記内部カバー部を支持し、かつ外側方向からの取り外しを防止する止め受け部を有し、前記機能ユニットに係合するカバー基材とを含むカバーユニット
を提供する。
【０００７】
外部及び内部カバー部がカバー基材の止め受け部に係支されているため、外部及び内部カバー部の外側方向からの取り外しを防止することができる。さらに、外部及び内部カバー部がともにカバー基材の止め受け部に係支される構成であるので、カバーユニットを容易に組み立てることができる。よって、カバーユニットの組立作業にかかる時間を短縮することができる。また、接着剤などによる固着が不要であり、分解作業が容易である。
本願第２発明は、カメラユニットを有するドーム型カメラのカバーにおいて、前記カメラユニットを覆うドーム状の外部カバー部と、前記外部カバー部の内側に沿うように設けられ、切り欠き部を有するドーム状の内部カバー部と、前記外部カバー部及び前記内部カバー部を支持し、かつ外側方向からの取り外しを防止する第１止め受け部を有し、前記カメラユニットに係合するリング状のカバー基材とを含み、前記外部カバー部は、前記カバー基材に対し固定されているか、または前記カバー基材及び前記内部カバー部に対して独立に回転可能に取り付けられているドーム型カメラのカバーを提供する。
【０００８】
外部カバー部が、カバー基材に対し固定されているか、またはカバー基材及び内部カバー部に対して独立に回転可能に取り付けられているため、カメラ設置後に外部カバー部が回転することにより内部カバー部の切り欠き部の方向が変えられてしまうことを防止できる。よって、カメラ撮影を行うための切り欠き部の方向とカメラ方向との不一致によるカメラの撮影機能の妨害を防止できる。例えば不透明材料から形成された内部カバー部の切り欠き部が、設置されたドーム型カメラの撮影方向と沿う方向に固定されている場合、外部から外部カバー部に外力を加えても外部カバー部が移動しないため内部カバー部が移動しないか、あるいは外部カバー部が移動しても内部カバー部は移動しない。そのため、切り欠き部の移動によりカメラの撮影機能が内部カバー部の不透明材料で覆われることがなく、撮影が妨害されない。
【０００９】
また、外部及び内部カバー部がカバー基材の第１止め受け部に係支されているため、外部及び内部カバー部の外側方向からの取り外しを防止することができる。さらに、外部及び内部カバー部がともにカバー基材の第１止め受け部に係支される構成であるので、カバー基材、外部及び内部カバー部からなるカバー部を容易に組み立てることができる。よって、カメラの設置作業が容易で、設置作業にかかる時間を短縮することができる。また、外部及び内部カバー部は、カバー基材に設けられた第１止め受け部に係支されるため、カバー部を組み立てるための別部品が不要である。さらに接着剤などによる固着が不要であり、カバー部を取り外す際の分解作業が容易である。
【００１０】
本願第３発明は、本願第２発明において、前記カバー基材は、前記第１止め受け部よりも前記カバー基材のカメラユニット側に設けられた第２止め受け部をさらに有し、前記外部カバー部の端部及び前記内部カバー部の端部は、前記カバー基材の第１止め受け部と第２止め受け部との間に係支されるドーム型カメラのカバーを提供する。
外部及び内部カバー部の端部がカバー基材の第１止め受け部に係支されているため、外部及び内部カバー部の外側方向からの取り外しを防止することができる。また、外部及び内部カバー部の端部が、カバー基材の第２止め受け部に係支されているため、外部及び内部カバー部がカバー基材のカメラユニット側に容易に外れないように位置決めされる。また、外部及び内部カバー部は、それぞれの端部がカバー基材に設けられた第１止め受け部及び第２止め受け部に係支されることによりカバー基材に係支される。よって、カバー基材、外部及び内部カバー部からなるカバー部を組み立てるための別部品や、接着剤などによる固着が不要であり、カバー部の組立作業や分解作業が容易である。
【００１１】
本願第４発明は、本願第３発明において、前記外部カバー部の端部は、前記カバー基材の第１止め受け部と前記内部カバー部の端部とにより係支され、前記内部カバー部の端部は、前記外部カバー部の端部と前記カバー基材の第２止め受け部とにより係支されるドーム型カメラのカバーを提供する。
内部カバー部の端部を係支するために外部カバー部の端部を利用しているため、係支のための別途の部品が不要である。
本願第５発明は、本願第３発明において、前記外部カバー部の端部及び前記内部カバー部の端部は、それぞれリング状の第１フランジ部及び第２フランジ部であり、前記カバー基材の第１止め受け部はリング状であり、前記第２止め受け部は前記カバー基材の内壁から突出する突出部であるドーム型カメラのカバーを提供する。
【００１２】
外部及び内部カバー部の端部がそれぞれリング状のフランジ部であり、そのフランジ部がカバー基材のリング状の第１止め受け部及び突出部である第２止め受け部に係支される。よって、例えばリング状の第１止め受け部に内部カバー部のリング状のフランジをスライドさせるように回転させ、切り欠き部の位置を容易に調整することができる。
本願第６発明は、本願第３発明において、前記カバー基材は、前記第１止め受け部と前記第２止め受け部との間に設けられた第３止め受け部をさらに有し、前記外部カバー部の端部は、前記カバー基材の第１止め受け部と前記第３止め受け部との間に係支され、前記内部カバー部の端部は、前記第３止め受け部と前記カバー基材の第２止め受け部との間に係支されるドーム型カメラのカバーを提供する。
【００１３】
内部カバー部の端部は、カバー基材の第２止め受け部と第３止め受け部とにより係支されるため、外部カバー部と内部カバー部との接触を低減することができる。よって、内部カバー部の切り欠き部を調整するために内部カバー部をカバー基材に対して容易に回転することができる。また、外部カバー部が回転した場合であっても、内部カバー部の回転を抑制することができる。
本願第７発明は、本願第２発明において、前記内部カバー部は、さらに前記カバー基材に対して可動であるドーム型カメラのカバーを提供する。
【００１４】
内部カバー部がカバー基材に対して可動であると、カバー基材がカメラユニットの固定位置に取り付けられる場合であっても、内部カバー部をカバー基材に対して移動させ、切り欠き部の位置調整を容易に行うことができる。
本願第８発明は、本願第３発明に記載のドーム型カメラのカバーの組立方法において、前記外部カバー部の端部を前記カバー基材のカメラユニット側から前記第１止め受け部に係支する第１係支ステップと、前記内部カバー部の端部を前記カバー基材のカメラユニット側から前記第２止め受け部に係支する第２係支ステップとを含むドーム型カメラのカバーの組立方法を提供する。
【００１５】
外部カバー部及び内部カバー部がともにカバー基材のカメラユニット側からカバー基材に係支されるので、カバー部を容易に組み立てることができる。よって、カメラの設置作業が容易で、設置作業にかかる時間が短縮される。
本願第９発明は、カメラユニットと、前記カメラユニットを覆うカバーとを有するドーム型カメラにおいて、前記カメラユニットを覆うドーム状の外部カバー部と、前記外部カバー部の内側に沿うように設けられ、切り欠き部を有するドーム状の内部カバー部と、前記カメラユニットに係合するリング状のカバー基材とを含み、前記カバー基材は、前記外部カバー部及び前記内部カバー部を支持し、かつ外側方向からの取り外しを防止する第１止め受け部と、前記第１止め受け部よりも前記カバー基材のカメラユニット側に設けられた第２止め受け部とを有する、ドーム型カメラを提供する。
【００１６】
前記第２発明及び前記第３発明と同様の効果を有するドーム型カメラを得ることができる。
本願第１０発明は、本願第９発明に記載のドーム型カメラの組立方法において、前記外部カバー部の端部を前記カバー基材のカメラユニット側から前記第１止め受け部に係支する第１係支ステップと、前記内部カバー部の端部を前記カバー基材のカメラユニット側から前記第２止め受け部に係支する第２係支ステップと、前記第１係支ステップと前記第２係支ステップとにより係支された前記カバー基材、前記外部カバー部及び前記内部カバー部を、前記カメラユニットに固定するカメラ固定ステップとを含むドーム型カメラの組立方法を提供する。
【００１７】
外部カバー部及び内部カバー部がともにカバー基材のカメラユニット側からカバー基材に係支されるので、ドーム型カメラのカバーを容易に組み立てることができる。また、カバー部をカメラユニットに固定し、設置する際、内部カバー部及び外部カバー部がカバー基材に係合し固定されているためドーム型カメラの設置作業が容易である。
【００１８】
【発明の実施の形態】
＜発明の概要＞
本発明のカバーユニットは、機能ユニットを覆う外部カバー部、外部カバー部の内側に沿うように設けられた内部カバー部及びカバー基材を有している。内部カバー部及び外部カバー部はカバー基材に係支される。外部カバー部及び内部カバー部とカバー基材とは、外部及び内部カバー部の外側方向からの取り外しを防止するように設けられた止め受け部により係支されている。このように内部カバー部、外部カバー部及びカバー基材が互いに係支されたカバーユニットは、カバー基材を介して機能ユニットに係合される。
【００１９】
上記のようなカバーユニットは、外部及び内部カバー部がカバー基材の止め受け部に係支されているため、外部及び内部カバー部の外側方向からの取り外しを防止することができる。さらに、外部及び内部カバー部がともにカバー基材の止め受け部に係支される構成であるので、カバーユニットを容易に組み立てることができる。よって、カバーユニットの組立作業にかかる時間を短縮することができる。また、接着剤などによる固着が不要であり、分解作業が容易である。
＜実施形態例＞
図１は、本発明の実施形態例に係るドーム型カメラの全体図、図２（ａ）は図１のカメラユニットの斜視図、図２（ｂ）は図１のカバー部の斜視図、図３は図１のカバー部の分解図、図４（ａ）〜（ｃ）は図１のカバー部の係合状態を示す拡大図である。以下に、本実施形態例のドーム型カメラ１の構成を説明する。
［構成］
本実施形態例に係るドーム型カメラ１は、撮影を行うためのカメラユニット３及びカメラユニット３を覆うためのカバー部５を有している。カメラユニット３は、カメラレンズ７、カメラ土台９、カメラ取付部１１及びシャーシ１３を有している。シャーシ１３は、カバー部５をカメラユニット３に係合するための第１係合受け部２１ａ、２１ｂ（第１係合受け部２１）を有している。カメラ土台９及びカメラ取付部１１は、カメラレンズ７の撮影方向の傾き及び回転を調整するために設けられており、所定の方向を撮影できるように調整される。
【００２０】
カバー部５は、図３に示すようにカメラユニット３に取り付けられるカバー基材２３、カメラユニット３を覆うドーム状の外部カバー部２５及び外部カバー部２５の内側に位置するドーム状の内部カバー部２７を有している。外部カバー部２５は、カメラユニット３を覆う中空の外部ドーム部２９と、外部ドーム部２９の縁に形成された例えばリング状のフランジから形成される第１端部３１とから構成されている。この外部カバー部２５は、後述の内部カバー部２７の切り欠き部３７からのゴミ等の侵入を防止し、カメラレンズ７等のカメラユニット３の性能低下を防止する。
【００２１】
一方、内部カバー部２７は、カメラユニット３を覆う中空の内部ドーム部３３と、内部ドーム部３３の縁に形成された例えばリング状のフランジから形成される第２端部３５とから構成されている。内部ドーム部３３は、外側ドーム部２９の内側に沿うような形状であり、内部ドーム部３３の側面の一部には、切り欠き部３７が形成されている。通常、この切り欠き部３７を介してカメラレンズ７により被写体を撮影する構成となっている。以下では、この切り欠き部３７を介して撮影が行われる場合を説明している。
【００２２】
上記外部カバー部２５及び内部カバー部２７は、外部カバー部２５の内側に沿うように内部カバー部２７を組み合わせた場合、内側からはカメラ撮影が可能であり、かつ外側からは内部カバー部２７の内部を視認できないように形成されている。つまり、内部カバー部２７の内側から内部カバー部２７及び外部カバー部２５を介してカメラユニット３によりカメラ撮影が可能であり、かつ外部カバー部２５の外側から外部カバー部２５及び内部カバー部２７を介して内部カバー部２７の内部を切り欠き部３７以外からは視認できない。よって、カメラユニット３によりカメラ撮影が行われていることや、カメラ撮影が行われている方向を外部から把握しにくい構成となっている。
【００２３】
このような外部カバー部２５は、例えば透明なプラスチック等の透明材料から形成されている。また、外部カバー部２５は、カメラユニット３を覆う側から外部カバー部２５外側の被写体のカメラ撮影は可能であるが、外部カバー部２５の外側から内部カバー部２７内部を視認できないようにハーフミラー加工されていても良い。一方、内部カバー部２７は、カメラユニット３が外側から視認できないように、例えば不透明材料から形成されている。このとき、内部カバー部２７に設けられた切り欠き部３７は、不透明材料が一部除去されて形成されている。また、切り欠き部３７は、不透明材料が一部除去され、カメラ撮影が可能な透明材料で形成されていても良い。さらに、内部カバー部２７は、前述のようにハーフミラー加工されていても良い。上記のような外部カバー部２５及び内部カバー部２７の材料の組み合わせとしては、例えば外部カバー部２５が透明材料で形成されている場合には、内部カバー部２７が不透明材料から形成され、不透明材料の一部が除去された切り欠き部３７を有するように形成されている。また、外部カバー部２５がハーフミラー加工されている場合は、内部カバー部２７は透明材料、不透明材料等で形成されている。
【００２４】
カバー基材２３は、例えば図２に示すようにリング状に形成されている。また、カバー基材２３は、図４に示すように第１係合部４１ａ、４１ｂ（第１係合部４１）、第１止め受け部４３及び第２止め受け部４５ａ、４５ｂ（第２止め受け部４５）を有している。第１止め受け部４３は、例えばリング状のカバー基材２３の内壁に沿って突出するようにリング状に形成されている。また、第２止め受け部４５は、カバー基材２３の内壁から突出する突出部であり、第１止め受け部４３よりもカメラユニット３側に設けられている。カバー基材２３への外部カバー部２５及び内部カバー部２７の係支は次のように行われる。外部カバー部２５の第１端部３１及び内部カバー部２７の第２端部３５が、第１止め受け部４３と第２止め受け部４５との間に係支されることで、外部カバー部２５及び内部カバー部２７がカバー基材２３に係合されている。つまり、図４（ｂ）に示すように外部カバー部２５の第１端部３１が、第１止め受け部４３により係支される。また、図４（ｃ）に示すように内部カバー部２７の第２端部３５の位置が、第２止め受け部４５により規制され、外部カバー部２５及び内部カバー部２７をカバー基材２３の所定位置に位置決めする。具体的には、外部カバー部２５の第１端部３１はカバー基材２３の第１止め受け部４３と内部カバー部２７の第２端部３５とにより係支され、内部カバー部２７の第２端部３５は、外部カバー部２５の第１端部３１とカバー基材２３の第２止め受け部４５とにより係支される。このとき、第２端部３５は、第１端部３１を介して第１止め受け部４３と係支されており、この第１止め受け部４３が外部カバー部２５及び内部カバー部２７の外側方向からの取り外しを防止している。また、前述のように、第２止め受け部４５は、外部カバー部２５及び内部カバー部２７がカバー基材２３のカメラユニット３側に容易に外れないように位置決めする。
【００２５】
ここで、外部カバー部２５は、カバー基材２３に対し固定されているか、またはカバー基材２３及び内部カバー部２７に対して独立に回転可能なように、第１及び第２端部３１、３５が第１及び第２止め受け部４３、４５に係支されている。よって、カメラ設置後に外部カバー部２５が回転することにより内部カバー部２７の切り欠き部３７の方向が変えられてしまうことを防止できる。例えば、不透明材料から形成された内部ドーム部３３の切り欠き部３７が、設置されたドーム型カメラ１の撮影方向と沿う方向に固定されている場合、外部から外部カバー部２５に外力を加えても外部カバー部２５が移動しないため内部カバー部２７が移動しないか、あるいは外部カバー部２５が移動しても内部カバー部２７は移動しない。そのため、カメラ撮影を行うための切り欠き部３７の方向とカメラユニット３のカメラ方向とが一致した状態であるため、カメラの撮影が妨害されない。さらに、内部カバー部２７がカバー基材２３に対して可動であっても良い。例えば、内部カバー部２７がカバー基材２３に対して可動であると、カバー基材２３がカメラユニット３の固定位置に取り付けられる場合であっても、内部カバー部２７をカバー基材２３に対して移動させ、切り欠き部３７の位置調整を容易に行うことができる。
【００２６】
上記のように互いに係支されたカバー基材２３、外部カバー部２５及び内部カバー部２７を、カメラレンズ７及びカメラ土台９を覆うようにカメラユニット３に取り付けドーム型カメラ１を完成する。このとき、カバー基材２３の第１係合部４１ａ及び４１ｂがそれぞれシャーシ１３の第１係合受け部２１ａ及び２１ｂに係合し、カバー基材２３とカメラユニット３とが固定される。このように外部カバー部２５及び内部カバー部２７は、カバー基材２３の第１止め受け部４３や第２止め受け部４５により係支されるため、係支のための別途の部品が不要であり、ドーム型カメラ１のコストを削減することができる。本実施形態のドーム型カメラ１では、外部カバー部２５及び内部カバー部２７とカバー基材２３とが、カバー基材２３のカメラユニット３側（図３中矢印参照）から係支される。
【００２７】
シャーシ１３の第１係合受け部２１及びカバー基材２３の第１係合部４１は、カメラユニット３とカバー部５とが係合される構造であれば良く、形状及び位置は上記に限定されない。また、第１端部３１及び第２端部３５は、第１止め受け部４３及び第２止め受け部４５に係支される構造であればフランジである必要はなく、また形状及び位置も上記に限定されない。第１止め受け部４３及び第２止め受け部４５の形状及び位置も上記に限定されない。上記のようにカバー基材２３がリング状に形成されており、カバー基材２３の形状に沿うように第１止め受け部４３がリング状にカバー基材２３の内壁から突出しているとする。また、外部カバー部２５の第１端部３１及び内部カバー部２７の第２端部３５がリング状のフランジであり、第２止め受け部４５がカバー基材２３の内壁から突出するように形成された突出部であるとする。このようなドーム型カメラ１においては、外部カバー部２５の第１端部３１のフランジがカバー基材２３から突出したリング状の第１止め受け部４３に引っかかるように係合される。また、内部カバー部２７の第２端部３５のフランジが外部カバー部２５の第１端部３１を介して間接的に第１止め受け部４３に係合される。よって、例えばリング状の第１止め受け部４３に内部カバー部２７のリング状のフランジをスライドさせるように回転させ、切り欠き部３７の位置を容易に調整することができる。
【００２８】
さらに、前述のように第２端部３５が第１端部３１と第２止め受け部４５との間に位置して係支される構成ではなく図５に示す構成であっても良い。図５のドーム型カメラ１のカバー基材２３は、さらに第３止め受け部４６を有している。ここで、外部カバー部２５の第１端部３１は第１止め受け部４３と第３止め受け部４６とにより係支され、内部カバー部２７の第２端部３５は、第３止め受け部４６と第２止め受け部４５とにより係支される。このとき、外部カバー部２５は内部カバー部２７に対して独立に可動なように係支されている。このような構成であると、外部カバー部２５と内部カバー部２７との接触を低減することができる。よって、外部カバー部２５が移動した場合であっても内部カバー部２７がともに移動することを防止することができる。また、外部カバー部２５との接触抵抗が小さいため、内部カバー部２７をカバー基材に対して回転することで切り欠き部３７の方向調整をスムーズに行うことができる。
［組立方法］
次に、組み立て方法について概説する。まず、外部カバー部２５の第１端部３１をカバー基材２３のカメラユニット３側から第１止め受け部４３に係支する。次に、内部カバー部２７の第２端部３５を、前述と同一の方向であるカバー基材２３のカメラユニット３側から第２止め受け部４５に係支する。つまり、図３中矢印方向に外部カバー部２５及び内部カバー部２７を順にカバー基材２３に係支する。このようにして係支された、カバー基材２３、外部カバー部２５及び内部カバー部２７からなるカバー部５をカメラユニット３に固定する。
［効果］
本実施形態例のドーム型カメラ１は、外部カバー部２５及び内部カバー部２７がともにカバー基材２３のカメラユニット３側からカバー基材２３に係支されるので、ドーム型カメラ１のカバーを容易に組み立てることができる。よって、ドーム型カメラ１の設置作業が容易で、設置作業にかかる時間が短縮される。また、取り付け作業前にカバー部５を組み立てておき、天井や壁への設置時にカバー部５をカメラユニット３に取り付けるため、天井や壁への取り付け作業を容易に行うことができる。
【００２９】
また、外部カバー部が、カバー基材に対し固定されているか、またはカバー基材及び内部カバー部に対して独立に回転可能に取り付けられているため、カメラ設置後に外部カバー部が回転することにより切り欠き部の方向が変えられてしまうことを防止できる。そのため、カメラ撮影を行うための切り欠き部３７の方向とカメラ方向とが一致した状態であるため、カメラの撮影が妨害されない。
さらに、外部カバー部２５及び内部カバー部２７は、それぞれのカバーが有する第１端部３１及び第２端部３５がカバー基材２３に設けられた第１止め受け部４３及び第２止め受け部４５に係支されることによりカバー基材２３に係合される。よって、カバー部５を組み立てるためのネジなどの別部品が不要である。また、接着剤などによる固着が不要であり、カバーを取り外す際の分解作業が容易である。また分解時などに無理な力を加えることによりカバー部５やカメラユニット３を傷つけることを防止できる。
【００３０】

また、本発明を用いれば、設置作業が容易なドーム型カメラのカバーを提供することができる。
また、本発明を用いれば、カメラ撮影が妨害されないドーム型カメラのカバーを提供することができる。

Cover unit, comprising: a cover member that supports the outer cover portion and the inner cover portion, and has a receiving portion that prevents removal from the outside, and engages with the functional unit.
I will provide a.
[0007]
Since the outer and inner cover portions are supported by the stopper receiving portions of the cover base material, the outer and inner cover portions can be prevented from being removed from the outside. Further, since the outer and inner cover portions are both supported by the stopper receiving portions of the cover base material, the cover unit can be easily assembled. Therefore, the time required for assembling the cover unit can be reduced. Further, it is not necessary to fix with an adhesive or the like, and the disassembling operation is easy.
