Description

本発明は、セキュリティカメラのように住宅内外に固定し撮影するカメラに関するものである。   The present invention relates to a camera that is fixed inside and outside a house, such as a security camera.
従来、住宅内外に固定し撮影するカメラは、特許文献1に提案されている。特許文献1に記載された技術を図5を用いて説明する。図によればカメラ本体8と取り付け部材9をボールジョイント11で接続されている。このカメラの角度調整は、ボールジョント11で接続され、自由に垂直、水平方向に移動、回転できるカメラ本体8を、被写体がカメラの撮影範囲に入るように移動した後、ボールジョイント11、締め付けねじ10を締め付けて行う。このように、従来のカメラは、取り付け部材9とカメラ本体8との間にボールジョイント11などの締め付け機構が必要であった。また、カメラは、水平、垂直方向以外にも移動できるので、角度調整した後、ファインダーなどの撮影範囲確認手段で調整する必要があった。
特開平7−147647号公報
Conventionally, a camera that is fixed inside and outside a house and shoots has been proposed in Patent Document 1. The technique described in Patent Document 1 will be described with reference to FIG. According to the figure, the camera body 8 and the attachment member 9 are connected by a ball joint 11. This camera angle adjustment is performed by moving the camera body 8 connected by the ball joint 11 and freely moving and rotating in the vertical and horizontal directions so that the subject falls within the shooting range of the camera. 10 is tightened. As described above, the conventional camera requires a tightening mechanism such as the ball joint 11 between the attachment member 9 and the camera body 8. In addition, since the camera can be moved in directions other than the horizontal and vertical directions, it is necessary to adjust the angle with a shooting range confirmation means such as a viewfinder after adjusting the angle.
JP-A-7-147647
上記従来のカメラは、取り付け部材とカメラ本体との間にボールジョイントなどの締め付け機構が必要であり、小型することは困難であった。また、カメラの角度調整は、回転方向の角度調整も必要であり、ファインダーなどの撮影確認手段なく角度調整することが困難であった。   The conventional camera requires a tightening mechanism such as a ball joint between the mounting member and the camera body, and it has been difficult to reduce the size. Further, the angle adjustment of the camera also requires the angle adjustment in the rotation direction, and it is difficult to adjust the angle without photographing confirmation means such as a viewfinder.
上記目的を達成するために、本発明の回転体カメラは、被写体を撮影する略球形のカメラ部と、前記カメラ部を取り付ける本体と、前記本体の裏側に配置され穴部が設けられた固定板とを有し、前記カメラ部の表面に溝部を設け、前記溝部に前記固定板に設けた突起部を嵌合させてなる。   In order to achieve the above object, a rotating body camera according to the present invention includes a substantially spherical camera unit for photographing a subject, a main body to which the camera unit is attached, and a fixing plate provided on the back side of the main body and provided with a hole. And a groove is provided on the surface of the camera unit, and a protrusion provided on the fixing plate is fitted into the groove.
以上の説明から明らかなように、本発明により、カメラ角度調整の締め付け機構が不要になり、カメラは上下、左右の移動のみに限定できるために、カメラの小型化、角度調整作業の時間短縮ができ、住宅内外に固定し撮影するカメラ角度調機構として実用的にきわめて有用である。   As is clear from the above description, the present invention eliminates the need for a tightening mechanism for camera angle adjustment, and the camera can be limited to only vertical and horizontal movements, thereby reducing the size of the camera and shortening the time for angle adjustment. It is practically extremely useful as a camera angle adjustment mechanism that can be fixed inside and outside the house and photographed.
上記本発明の構成によれば、カメラをいれた回転体が一定の力で保持されているために、ボールジョイントなどの締め付け機構を不要にすることができ、かつ、回転体の移動を水平、垂直方向のみにすることができる。   According to the configuration of the present invention, since the rotating body in which the camera is inserted is held with a constant force, a tightening mechanism such as a ball joint can be made unnecessary, and the movement of the rotating body is horizontal. It can only be in the vertical direction.
以下に本発明の一実施の形態について説明する。まず、図1において、1で示すのはカメラ、2で示すのはカメラを取り付ける本体である。このカメラ1は、球体の形をしており、この球の半分が表に現れ、残りの半分は本体内に収納されている。。そのカメラ1は、本体2に開けられた、カメラ1を構成する球中心を通る断面の面積より小さい面積の円状の穴の裏側から表側に円状の穴に接触させて表に出すよう構成されている。   An embodiment of the present invention will be described below. First, in FIG. 1, a reference numeral 1 indicates a camera, and a reference numeral 2 indicates a main body to which the camera is attached. The camera 1 has a spherical shape, half of the sphere appears on the table, and the other half is stored in the main body. . The camera 1 is configured to be brought out of contact with the circular hole from the back side to the front side of the circular hole having a smaller area than the cross-sectional area passing through the center of the sphere constituting the camera 1. Has been.
図2は、図1に示すa−a’断面、図3は、図1に示すb−b’断面を表す断面図である。カメラ1を本体2に取り付ける方法を、図2、図3を使って説明する。図において、3で示すはカメラ1を本体2の裏側から押さえる固定板である。本実施の形態において、この固定板3は、カメラ1を構成する球の中心を通る断面の半径より短い半径を有する円形の穴があいている。4で示すのはコイルばね、5はコイルばね4が通る取り付けボス、6はねじ、7は押さえ板である。   2 is a cross-sectional view taken along the line a-a ′ shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line b-b ′ shown in FIG. 1. A method of attaching the camera 1 to the main body 2 will be described with reference to FIGS. In the figure, reference numeral 3 denotes a fixing plate that holds the camera 1 from the back side of the main body 2. In the present embodiment, the fixed plate 3 has a circular hole having a radius shorter than the radius of the cross section passing through the center of the sphere constituting the camera 1. Reference numeral 4 denotes a coil spring, 5 denotes a mounting boss through which the coil spring 4 passes, 6 denotes a screw, and 7 denotes a pressing plate.
図2に示すように、円状の穴が開いている本体2に、裏側から球状のカメラ1を接触させる。このとき、カメラ1が本体2より表に出ずに、本体2と接触できるようにするために、本体2に開ける円状の穴の直径は、球の中心を通る断面円の直径より小さくする。このことで、本体2の裏側から、球状のカメラ1の裏側から力を加えても、カメラ1全体が本体2から出ないようにできる。   As shown in FIG. 2, a spherical camera 1 is brought into contact with the main body 2 having a circular hole from the back side. At this time, the diameter of the circular hole opened in the main body 2 is made smaller than the diameter of the cross-sectional circle passing through the center of the sphere so that the camera 1 can come into contact with the main body 2 without coming out from the main body 2. . Thus, even if a force is applied from the back side of the main body 2 from the back side of the spherical camera 1, the entire camera 1 can be prevented from coming out of the main body 2.
次に、ねじ取り付けボス5は、本体2と一体構造しており、カメラ1を押さえる固定板3には、ねじ取り付けボス5が通る穴が、図2に示すように開いている。この固定板3にある穴にねじ取り付けボス5を通して、固定板3設けた円形の穴にカメラ1がひっかかり本体2の裏側に落ちないようを押さえる。   Next, the screw mounting boss 5 is integrally formed with the main body 2, and a hole through which the screw mounting boss 5 passes is opened in the fixing plate 3 that holds the camera 1 as shown in FIG. 2. Through the screw mounting boss 5 through the hole in the fixing plate 3, the camera 1 is caught in the circular hole provided in the fixing plate 3 so as not to fall on the back side of the main body 2.
次に、この固定板3が常にカメラ1を本体2の裏側から押さえ続けるために、ねじ取り付けボス5に固定板3を通したのちに、それぞれのねじ取り付けボス5にコイルばね4を通す。そして、これを押さえ板7でコイルばね4を縮めることで、固定板3でカメラ1を本体2の裏側か押さえる力が発生する。固定板3でカメラ1を本体2の裏側から本体2に押さえつける力を、押さえ板7をねじ6の締め付ける長さで調整することができる。   Next, in order for the fixing plate 3 to always hold the camera 1 from the back side of the main body 2, after passing the fixing plate 3 through the screw mounting boss 5, the coil spring 4 is passed through each screw mounting boss 5. Then, by contracting the coil spring 4 with the pressing plate 7, a force for pressing the camera 1 against the back side of the main body 2 with the fixing plate 3 is generated. The force with which the camera 1 is pressed against the main body 2 from the back side of the main body 2 with the fixing plate 3 can be adjusted by the length with which the press plate 7 is tightened with the screws 6.
なお、押さえ板7は、ねじ取り付けボス5にねじ6で締め付けるように、穴を開けている。このとき、カメラ1、本体2の円状の穴、固定板3、押さえ板7の中心点は、カメラ球体の中心線上にくるようにすることで、押さえ板7で押さえと回転の2つの機能を実現することができる。このような、機構にすることで、球状のカメラ1を垂直、水平方向の回転は、本体2に設けた円形の穴の縁部分と固定板3に設けた円形の穴の縁分とカメラ1の表面とが接触により発生している摩擦力で保持されている。このため、ボールジョイントなどの角度調整時に、締め付け構造が不要になり、小型化が実現できる。   The presser plate 7 has a hole so as to be fastened to the screw mounting boss 5 with the screw 6. At this time, the center point of the camera 1, the circular hole of the main body 2, the fixed plate 3, and the holding plate 7 is positioned on the center line of the camera sphere, so that the holding plate 7 can hold and rotate. Can be realized. By using such a mechanism, the spherical camera 1 is rotated in the vertical and horizontal directions so that the edge of the circular hole provided in the main body 2 and the edge of the circular hole provided in the fixing plate 3 and the camera 1 are rotated. The surface is held by the frictional force generated by contact. For this reason, when adjusting the angle of the ball joint or the like, a tightening structure is not necessary, and downsizing can be realized.
さらに、図4に示すように、固定板3のに設けた穴部の縁部には鉛直方向を軸として回転可能に取り付けられた突起部を図の様に上下2箇所設けて回転軸とし、カメラ1の球面上には、その回転軸をスライドさせる溝を上下に彫り、その溝と押さえ板3の回転軸を嵌合わす。   Furthermore, as shown in FIG. 4, the protrusions attached to the edge of the hole provided in the fixed plate 3 so as to be rotatable about the vertical direction are provided at two upper and lower portions as shown in the figure to serve as a rotation shaft. On the spherical surface of the camera 1, a groove for sliding the rotation axis is carved up and down, and the groove and the rotation axis of the holding plate 3 are fitted.
カメラ1は、嵌め合わした回転軸を溝に沿って上下に回転し、上下に回転した位置で回転軸を中心に左右に回転できる。上下の回転限界は、このスライドの長さで決めることができる、左右の回転の限界は、球の左右方向に2箇所ストッパーを設けることで実現することができる。溝は小判型や長方形形状に掘ることが好ましい。 また、回転軸は穴部の縁部に設ける以外にも、固定板の側面に垂直な棒状部を儲け、この棒状部の先端に棒状部とは直角に回転軸を設け、溝に嵌合させてもよい。   The camera 1 can rotate up and down along the groove along the fitted rotation shaft, and can rotate left and right around the rotation shaft at a position rotated up and down. The upper and lower rotation limits can be determined by the length of this slide. The left and right rotation limits can be realized by providing two stoppers in the left and right direction of the sphere. The groove is preferably dug into an oval or rectangular shape. In addition to providing the rotating shaft at the edge of the hole, a rod-shaped portion perpendicular to the side surface of the fixing plate is provided, and a rotating shaft is provided at the tip of the rod-shaped portion at a right angle to the rod-shaped portion and fitted into the groove. May be.
また、この摩擦力は、押さえ板7を締め付けるねじ6の締め付ける長さで調整でき、カメラ1の押さえと回転する力を調整することができる。このことで、各部材のバラツキ、角度調整力の調整をすることができる。さらに、固定板3をアセタール樹脂製にすることで、滑らかにカメラ1を回転して角度調整をすることができる。   The frictional force can be adjusted by the length of the screw 6 that fastens the presser plate 7, and the pressing force of the camera 1 and the rotating force can be adjusted. Thereby, the variation of each member and the angle adjusting force can be adjusted. Furthermore, by making the fixing plate 3 made of acetal resin, the camera 1 can be smoothly rotated to adjust the angle.
本発明は、カメラの角度調整機構を有する回転体カメラに関するものであるため、例えば住宅内外に固定し撮影するカメラに用いれば、セキュリティーシステムによるサービス性を向上させることができる。   Since the present invention relates to a rotating body camera having a camera angle adjustment mechanism, the serviceability of the security system can be improved, for example, when used in a camera that is fixed inside and outside a house.
