DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera support device for supporting a camera on a predetermined installation surface such as a wall surface or a ceiling surface in a surveillance camera device using a television camera.

[0002]

2. Description of the Related Art Conventionally, as a camera supporting device of this type, there is one disclosed in Japanese Patent Application Laid-Open No. 7-303201.

FIG. 9 is a view showing a supporting device of the camera. Note that FIG. 9 shows a state in which the camera unit 102 is mounted on a vertical installation surface 110 such as a wall surface. The vertical direction is the Z axis, the direction orthogonal to the installation surface 110 is the Y axis, and these Y axes, The direction orthogonal to the Z axis is defined as the X axis.

[0004] The camera support device has an installation surface 11 on a chassis 103 having a back surface 103 a attached to the installation surface 110.
The support unit 104 is integrally formed along the direction orthogonal to the direction 0, and the camera unit support 101 is provided at the tip of the support unit 104 so as to be rotatable 360 degrees around the vertical Z axis.
Are attached to the support 101, and 36 around the X axis.
The camera unit 102 is rotatably supported by 0 degrees. These support portions 104 and camera unit support 101
Is supported by the chassis 103.

[0005] Further, the support mechanism and the camera unit 1
A dome-shaped cover 105 is detachably attached so as to cover the entirety of the dome-shaped cover 02.
The camera unit 102 is formed in a size that does not hinder the rotation of the camera unit 102 in all directions. When the camera unit 102 is rotated to adjust or change its posture, that is, when the imaging range is adjusted or changed, the dome-shaped cover 105 is removed from the chassis 103 and then directly to the camera unit 102. The posture is adjusted or changed by touching.

The camera unit 102 has a built-in lens 107, an image pickup device, etc., and is finished in a substantially cubic shape.
The printed wiring board unit 106 provided in the chassis 103 and the camera unit 10
2 is made.

In this camera unit, the lens 10
An image in a predetermined range according to the characteristic of 7 is collected by an image pickup device such as a CCD and converted into a video signal here.

When the camera unit 102 is mounted on a vertical installation surface 110 such as a wall surface as shown in FIG. 9, the direction of the lens 107 of the camera unit 102 is directed upward from a direction perpendicular to the installation surface 110. When the camera unit is rotated to the position, the field of view is blocked by the camera unit support 101. Therefore, this camera unit 1
The imageable range of 02 is within a range of 90 degrees downward around the X-axis and within a range of ± 90 degrees in the left-right direction around the Z-axis, and can be fixed at any position between them. Configuration. For this reason, as a support device for a camera for mounting on a wall surface, a sufficient imaging range is provided.

[0009]

However, if the camera 103 is mounted on a horizontal installation surface 110 such as a ceiling surface while the camera unit 102 is kept in the posture shown in FIG. Looking straight down. When monitoring the horizontal direction from there, the lens 1
If the camera unit is rotated toward the camera unit support 101 and the support unit 104, there is a problem. However, if the camera unit 102 is rotated in the opposite direction, an image in the horizontal direction can be obtained. However, in this case, the top mark 102a of the camera unit 102 shown in FIG. 9 comes down, and the image is turned upside down. To prevent this, the camera unit 102 is set so that the top mark 102a is on the upper side.
Must be removed and re-attached.

That is, when the installation position of the camera unit 102 is to be re-installed from the ceiling surface to the wall surface, for example, the installer needs to directly touch the camera unit 102 in the chassis 103 with his / her hand to change the posture or re-attach. Therefore, these operations are complicated, and at this time, dust easily enters the inside of the surveillance camera device, causing a failure. Furthermore, since a force is directly applied to the camera unit 102, there also arise problems such as shaft shake of the rotating shaft and reduced monitoring position accuracy.

To avoid this, the chassis 10
It is also possible to adopt a configuration in which the upper portion 103b of the third 3 is attached to the ceiling surface.

However, in order to be able to attach to both the horizontal and vertical installation surfaces, both the rear surface 103a and the upper portion 103b of the chassis 103 have the installation surface 110
Protrudingly forming the mechanism for attachment to the camera has a problem from the viewpoint of aesthetics and the like.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a camera capable of supporting a camera in the same posture on installation surfaces in different plane directions, and preventing a mounting mechanism on an unused installation surface from projecting outside. To provide a supporting structure.

[0014]

Means for Solving the Problems In order to solve the above problems,
The invention according to claim 1 is a camera support device for supporting the camera with respect to an installation surface, comprising a pair of mounting surface portions continuously provided so as to intersect at a first intersection angle,

Arranged inside the line, the pair It is rotatably supported about an axis along the line of intersection of the mounting surface portion, in which the second intersection angle is set smaller than the first intersection angle.

[0015] The second intersection angle of the mounting member may be set such that one of the mounting plate members is inscribed in the corresponding mounting surface portion as described in claim 2. In a state where the mounting protrusions of the mounting plate member on one side are projected outward from the corresponding through holes of the mounting surface portion, the mounting protrusion portions of the mounting plate member on the other side correspond to the mounting protrusion portions. The angle may be set so as to be retracted inside the through hole.

The angle may be set to be the same as the angle at which the plane intersects.
