Description

本発明は、監視用ビデオカメラを設置面に取付け固定するための取付部構造に関するものである。   The present invention relates to an attachment structure for attaching and fixing a surveillance video camera to an installation surface.

従来の監視用カメラは、天井等の設置面に設置する際、設置面に設けた開口穴にカメラ本体部に設けた挿着部(取付部)を挿入して、挿着部をネジ締め等により固定する方法が一般的である。さらにカメラを簡単にあるいは確実に取付けるため、各種の方法が提案されている。   When installing a conventional surveillance camera on an installation surface such as a ceiling, insert the insertion part (attachment part) provided in the camera body into the opening hole provided on the installation surface, and tighten the insertion part with screws. The fixing method is generally used. In addition, various methods have been proposed in order to attach the camera easily or reliably.

特許文献1では、カメラを短時間で容易に取付けることを目的とし、柱状挿着部の側面を付勢手段(板バネなど)により設置面へ係着させる構造が開示される。特許文献2では、カメラを任意の位置に設置でき落下防止を図ることを目的とし、まず専用の取付金具を設置面に取付け、カメラを取付金具に組み込み、さらにカメラの落下防止のためフックを取付けた構造が開示される。   Patent Document 1 discloses a structure in which a side surface of a columnar insertion portion is engaged with an installation surface by a biasing means (such as a leaf spring) for the purpose of easily attaching a camera in a short time. In Patent Document 2, the purpose is to prevent the camera from being dropped at an arbitrary position. First, a dedicated mounting bracket is mounted on the installation surface, the camera is mounted on the mounting bracket, and a hook is mounted to prevent the camera from falling. Disclosed structures are disclosed.

監視カメラを狭い設置場所に取付けるためには、カメラの取付部構造はできるだけ簡単な構造とし、設置作業ができるだけ短時間で完了することが要求される。従来のネジ締め方法は簡単な構造であるが、カメラ取付部を取付けナット等で締め付けるとき、カメラ本体部も一緒に回転してカメラの撮影方向が変わってしまう欠点がある。これを防止するため、カメラの向きを規制するための別のネジ等で固定する方法がある。しかし、そのために新たなネジ穴を設ける必要があり、また取付けの作業時間が増加する。   In order to attach the surveillance camera to a narrow installation place, it is required that the attachment part structure of the camera is as simple as possible and that the installation work is completed in as short a time as possible. The conventional screw tightening method has a simple structure, but when the camera mounting part is tightened with a mounting nut or the like, there is a drawback that the camera body part also rotates together and the photographing direction of the camera changes. In order to prevent this, there is a method of fixing with another screw or the like for regulating the orientation of the camera. However, it is necessary to provide a new screw hole for this purpose, and the work time for mounting increases.

特許文献1の方法は、ネジ締めで固定するのではなく板バネの付勢力で固定するので、簡単な構造である。しかし、基本的にカメラの向きを規制する機能はなく、ネジ締め同様に向きが変わる恐れがある。また、ネジ締め方法に比較して、カメラの落下防止に対する信頼性が懸念される。   The method of Patent Document 1 has a simple structure because it is not fixed by screw tightening but fixed by the urging force of a leaf spring. However, there is basically no function for restricting the orientation of the camera, and there is a risk that the orientation will change as with screw tightening. In addition, there is a concern about the reliability of preventing the camera from dropping compared to the screw tightening method.

特許文献2の方法は、取付金具にカメラの方向をガイドするガイドカバーを設けているので、カメラの方向は正しく設定される。しかし、取付金具自身が新たに必要となり、設置場所もその分広く必要とし、また取付けの作業時間も増大する。   In the method of Patent Document 2, a guide cover for guiding the direction of the camera is provided on the mounting bracket, so that the direction of the camera is set correctly. However, the mounting bracket itself is newly required, the installation place is also required to be wide, and the installation work time is increased.

本発明の目的は、狭い設置場所に対応するため、カメラの取付部構造が簡単で短時間で作業ができ、カメラの向きを正しく設定できる監視用ビデオカメラの取付部構造を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a mounting structure for a surveillance video camera that can be set in a short time and can be set in a correct manner so that the camera mounting structure is simple and can be operated in a short time. .

本発明は、監視用ビデオカメラを設置面に取付け固定する際の取付部構造であって、監視用ビデオカメラのベース取付部は、円筒形状の側面にネジ山を形成するとともに、ベース取付部の先端には工具を差し込むための作業用穴を設ける。取付けの際、ベース取付部を設置面に設けた取付け穴に装着し、取付けナットを用いて設置面に締め付け固定する。   The present invention is a mounting portion structure for mounting and fixing a surveillance video camera on an installation surface. The base mounting portion of the surveillance video camera forms a thread on a cylindrical side surface and A work hole for inserting a tool is provided at the tip. When mounting, attach the base mounting part to the mounting hole provided on the installation surface, and tighten and fix it to the installation surface using a mounting nut.

本発明によれば、監視用ビデオカメラの取付け作業が簡単で、短時間で作業ができ、かつ、カメラの向きを正しく設定することができる。特に、狭い設置場所での取付け作業が容易になる。   According to the present invention, it is easy to attach the surveillance video camera, the work can be performed in a short time, and the direction of the camera can be set correctly. In particular, installation work in a narrow installation place is facilitated.

以下、本発明の実施の形態を図面を用いて説明する。
図1は、本発明にかかる監視用ビデオカメラの取付部構造の一実施例を示す図である。
図1(a)は、監視用ビデオカメラ1からカバー4を取り外した状態を示す図である。撮影レンズ2aなどを含むカメラユニット2はシャーシ3とともにベース部5にネジで固定されている。ベース取付部5aは、円筒形状の側面にネジ山が形成されていて、天井等の設置面に設置固定される部分である。またカバー4は、カメラユニット2を外部から保護し、あるいはカメラの撮影自身を目立たないようにするためのもので、カメラユニット2にドーム状のカバーを取付けて使用する。ベース取付部5aの先端には、取付け作業に用いる作業用穴6(丸穴6aまたはU字状の切り欠き6b)を形成している。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing an embodiment of a mounting structure of a surveillance video camera according to the present invention.
FIG. 1A is a diagram showing a state where the cover 4 is removed from the surveillance video camera 1. The camera unit 2 including the taking lens 2a and the like is fixed to the base portion 5 together with the chassis 3 with screws. The base attachment portion 5a is a portion where a screw thread is formed on a cylindrical side surface and is fixed to an installation surface such as a ceiling. The cover 4 is used to protect the camera unit 2 from the outside or to make the camera photographing itself inconspicuous, and is used with a dome-shaped cover attached to the camera unit 2. A work hole 6 (round hole 6a or U-shaped notch 6b) used for attachment work is formed at the tip of the base attachment portion 5a.

図1(b)は、監視用ビデオカメラ1を天井の設置面に取付ける工程を示す図である。設置面7には、ベース取付部5aを挿着するための取付け穴7aを1個開けておく。そしてカメラ全体を矢印Z方向に引き上げて、ベース取付部5aを取付け穴7aに挿着する。引き上げる際、カメラ用のケーブル9を取付け穴に通し、ケーブル9の先端を天井裏から引き上げることもできる。カメラを引き上げたら、取付けナット8を用いて、ベース取付部5aを締め付け、天井板7に固定する。   FIG. 1B is a diagram illustrating a process of attaching the monitoring video camera 1 to the installation surface of the ceiling. In the installation surface 7, one mounting hole 7a for inserting the base mounting portion 5a is opened. Then, the entire camera is pulled up in the direction of the arrow Z, and the base mounting portion 5a is inserted into the mounting hole 7a. When pulling up, the cable 9 for the camera can be passed through the mounting hole, and the tip of the cable 9 can be pulled up from the back of the ceiling. When the camera is lifted, the base attaching portion 5a is tightened by using the attaching nut 8 and fixed to the ceiling board 7.

図1(c)は、取付けナット8で固定を完了した状態である。本実施例ではベース取付部5aに設けた作業用穴6を利用することで、監視用ビデオカメラ1の向きを正しく、かつ短時間で設置面7へ取付けることができる。   FIG. 1C shows a state in which the fixing with the mounting nut 8 is completed. In the present embodiment, by using the working hole 6 provided in the base mounting portion 5a, the monitoring video camera 1 can be mounted on the installation surface 7 in the correct direction in a short time.

図2は、本実施例におけるベース取付部5aの作業用穴6の構造について詳細に示す図である。作業用穴6としては各種の構造が可能である。なお、図2では作業用穴6の形状を分かりやすくするために、ベース取付部5aの円筒面に形成したネジ山を省略している。   FIG. 2 is a diagram showing in detail the structure of the working hole 6 of the base mounting portion 5a in the present embodiment. Various structures are possible for the working hole 6. In FIG. 2, in order to make the shape of the working hole 6 easy to understand, the thread formed on the cylindrical surface of the base mounting portion 5a is omitted.

(a)は、ベース取付部5aの先端の径方向に対向する位置に、U字状切り欠き6bを2個ほぼ対称に設けたものである(タイプ1)。この切り欠き6bは、例えばドライバ等の工具を差し込んで、ナット締め付け時にベース部5が回転するのを防止するためのものである。なお、ビス5bはベース部5にカメラユニット2を固定するものである。   (A) is one in which two U-shaped notches 6b are provided approximately symmetrically at a position in the radial direction of the tip of the base mounting portion 5a (type 1). The notch 6b is for inserting a tool such as a driver to prevent the base portion 5 from rotating when the nut is tightened. The screws 5b are for fixing the camera unit 2 to the base portion 5.

(b)は、ベース取付部5aの先端の対向する位置に、丸穴6aと切り欠き6bを設けたものである(タイプ2)。この場合も、丸穴6aと切り欠き6bは、ベース部5が回転するのを防止することを含め、後述するようにカメラ取付け作業性の改善を図るためのものである。   (B) is one in which a round hole 6a and a notch 6b are provided at a position opposite to the tip of the base mounting portion 5a (type 2). Also in this case, the round hole 6a and the notch 6b are for improving the camera mounting workability as will be described later, including preventing the base portion 5 from rotating.

(c)は、ベース取付部5aの先端に丸穴6aを2個ほぼ対称に設け、さらに丸穴6aの中間に切り欠き6bを設けたものである(タイプ3)。   (C) is one in which two round holes 6a are provided approximately symmetrically at the tip of the base mounting portion 5a, and a notch 6b is provided in the middle of the round hole 6a (type 3).

なお、これらの作業用穴6の構造は一例であり、カメラの設置環境に応じて、丸穴6aと切り欠き6bを適宜組み合わせて最適な構造を採用すれば良い。   The structure of these working holes 6 is an example, and an optimal structure may be adopted by appropriately combining the round holes 6a and the notches 6b according to the installation environment of the camera.

図3は、カメラ取付け作業において、上記作業用穴の利用方法を具体的に説明する図である。ここでは、エレベータの天井鉄板に開けた取付け穴7aに、図2(b)すなわちタイプ2のベース取付部5aを持つカメラを設置する場合を想定する。   FIG. 3 is a diagram for specifically explaining a method of using the work hole in the camera mounting work. Here, it is assumed that a camera having FIG. 2B, that is, a type 2 base mounting portion 5a is installed in the mounting hole 7a formed in the ceiling iron plate of the elevator.

(a)は、ベース取付部5aの作業用穴の形状(タイプ2、丸穴6aと切り欠き6bを有する)を再度示す図である。   (A) is a figure which shows again the shape (it has type 2, the round hole 6a, and the notch 6b) of the hole for work of the base attachment part 5a.

(b)は、カメラを設置面へ引き上げるときに、予め針金のような引上げ線11を丸穴6aに通しておき、引上げ線11を引き上げることで、天井裏の作業者1人だけで作業ができる。すなわち、従来必要とされたエレベータのカゴ内でカメラを支えるための作業者が不要になる。   In (b), when pulling up the camera to the installation surface, a pulling wire 11 such as a wire is passed through the round hole 6a in advance, and the pulling wire 11 is pulled up so that only one worker behind the ceiling can work. it can. That is, an operator for supporting the camera in the elevator car, which is conventionally required, becomes unnecessary.

(c)は、カメラを取付け穴7aに通した後、取付け用六角ナット8をスパナ等で回して固定するが、最後に締め付ける際に、力が入りすぎるとカメラ全体が一緒に回転してしまい向きが変わってしまう。そのため、締める作業を行う際に、作業用穴6a、6bにドライバ12などの工具を差し込んで固定し、カメラが回転するのを防止する。つまり作業者は、スパナに加える力とドライバ12に加える力をバランスさせることで、カメラの回転を防止しながら設置面へ取付けることができる。   (C), after passing the camera through the mounting hole 7a, the mounting hex nut 8 is turned and fixed with a spanner or the like, but when tightening the last, if the force is excessive, the entire camera rotates together. The direction will change. Therefore, when performing the tightening work, a tool such as a screwdriver 12 is inserted and fixed in the work holes 6a and 6b to prevent the camera from rotating. That is, the operator can attach to the installation surface while preventing rotation of the camera by balancing the force applied to the spanner and the force applied to the driver 12.

その際、作業用穴6は、タイプ2のように一方は丸穴6aで他方がU字状切欠き6bとしたので、ドライバ12は水平でなく斜めに挿入されることになる。エレベータ天井裏での作業は、非常に狭い空間で行われることが多いのであるが、作業者はドライバを斜めに持つことで中腰姿勢でも容易に作業ができる。   At this time, since the working hole 6 is a round hole 6a and the other is a U-shaped notch 6b as in the type 2, the driver 12 is inserted not diagonally but obliquely. The work behind the elevator ceiling is often performed in a very small space, but the operator can easily work even in the middle waist posture by holding the driver diagonally.

(d)カメラの設置位置は、エレベータ室の壁13a,13bが交わる四隅となる場合が多く、(c)で用いるドライバ12の方向によっては、作業が困難な場合が発生する。例えば(d)のようなドライバ配置は作業性が悪い。   (D) The installation position of the camera is often at the four corners where the walls 13a and 13b of the elevator room intersect, and depending on the direction of the driver 12 used in (c), the operation may be difficult. For example, the driver arrangement as shown in FIG.

(e)は作業性の良いドライバ配置であり、ドライバ12の方向が隅13cの方向になるよう作業用穴を設けた場合である。作業者は天井裏の中央側で作業ができるので、(d)に比べて作業性を改善することができる。   (E) is a driver arrangement with good workability, in which work holes are provided so that the direction of the driver 12 is in the direction of the corner 13c. Since the worker can work on the center side of the ceiling, workability can be improved compared to (d).

(f)は、切り欠き6bの方向をカメラ本体1の撮影レンズ2aの向きと一致させておく。あるいは所定の角度だけずらしておく。作業者は、エレベータの天井裏にいながらにして、切欠き6bの方向によりレンズの向きを把握でき、カメラの撮影方向を誤って設置することがない。   In (f), the direction of the notch 6b is made to coincide with the direction of the photographing lens 2a of the camera body 1. Alternatively, it is shifted by a predetermined angle. The operator can grasp the direction of the lens from the direction of the notch 6b while staying behind the ceiling of the elevator, so that the photographing direction of the camera is not set by mistake.

(g)は、切り欠き6bをハーネス(信号線)14の引き出し部として使用する場合である。一般に信号線は、天井方向の高さが低い空間に収納せねばならないので、取付部5aから切り欠き6bを通して引き出すことで、高さが低い空間でも収納が容易になる。   (G) is a case where the notch 6 b is used as a lead-out portion of the harness (signal line) 14. In general, since the signal line has to be stored in a space with a low height in the ceiling direction, the signal line can be easily stored in a space with a low height by being pulled out from the mounting portion 5a through the notch 6b.

(h)は、カメラ取付け後、カメラ落下防止策として作業穴6a,6b部分にバインド線15などを巻き付けておく。線材として硬くスタイル取り出来る素材を通してから、ナットよりも上のネジ山部分に巻き付ける。取付けナット8が仮にゆるんだ場合でも、ナット外れを防止し、カメラの落下を防止できる。   In (h), after the camera is mounted, the bind wire 15 or the like is wound around the work holes 6a and 6b as a camera fall prevention measure. After passing through a stiff material that can be styled as a wire, wrap it around the thread above the nut. Even if the mounting nut 8 is loosened, it is possible to prevent the nut from coming off and to prevent the camera from dropping.

上記説明は、ベース取付部5aが図2(b)(タイプ2)の場合としたが、図2(a)(タイプ1)や図2(c)(タイプ3)の場合にも一部が該当することは明らかである。   The above description is based on the case where the base mounting portion 5a is shown in FIG. 2 (b) (type 2), but a part of the case is shown in FIG. 2 (a) (type 1) and FIG. 2 (c) (type 3). Obviously, this is true.

本実施例によれば、カメラを設置するために設置面に設ける取付け穴7aは1箇所のみである。そしてこれをナットで締め付けて固定するだけなので、作業は非常に簡単であり、取付けの作業時間が短縮できる。その際、カメラ取付部に設けた作業用穴にドライバを差し込んでカメラの回転を防止できるので、カメラの向き(撮影方向)を正確に設定することができる。作業用穴を利用することで、エレベータの天井の隅等の狭い場所でも、作業者1人で容易に設置作業を行うことができる。   According to the present embodiment, there is only one mounting hole 7a provided on the installation surface for installing the camera. And since it is only tightened and fixed with a nut, the operation is very simple, and the installation work time can be shortened. At this time, since the driver can be prevented from being rotated by inserting a driver into a work hole provided in the camera mounting portion, the direction of the camera (shooting direction) can be accurately set. By using the work holes, one worker can easily perform the installation work even in a narrow place such as the corner of the ceiling of the elevator.

上記実施例は一例であり、エレベータにおける監視ビデオカメラ設置だけに限らず、設置場所が狭く、作業性の悪い環境において同様に適用できる。   The above embodiment is merely an example, and is not limited to installation of a surveillance video camera in an elevator, but can be similarly applied in an environment where the installation place is narrow and workability is poor.
