Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a ceiling surface, a wall surface,
The present invention relates to a security camera device that can be attached to any surface such as a tabletop.

[0002]

2. Description of the Related Art In general, a security camera apparatus is to prevent a crime or the like from occurring by monitoring a specific place or range through a security camera. Therefore, the security camera is supported via a direction adjusting mechanism in a main body case fixed to the mounting surface, so that the monitoring direction of the security camera can be adjusted.

Conventionally, such a direction adjusting mechanism has only two rotation axes for adjusting the direction, and the two rotation axes are used for photographing a normal image in which the vertical direction of the image is correct. The security camera must be mounted on a horizontal surface such as a ceiling or tabletop.
It is uniquely determined depending on whether it is mounted on a vertical surface such as a wall surface, and the rotation axis of the direction adjusting mechanism is different depending on whether it is mounted on a horizontal surface or mounted on a vertical surface.

[0004]

Therefore, for example, when a security camera device manufactured to be mounted on a ceiling surface is to be mounted on a wall surface, two required rotation axes are different, so that security is required. A part called an adapter for wall mounting must be prepared separately from the camera device, and must have a rotation axis for direction adjustment required for mounting on a wall. Therefore, as compared with a case where the security camera device is directly attached, the size is increased and the appearance is complicated, so that a compact and smart appearance cannot be realized.

Conversely, when a security camera device manufactured to be mounted on a wall surface is mounted on a ceiling surface, another component called a ceiling surface mounting adapter is required, and there is a similar problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a security camera device which can be mounted on a horizontal surface or a vertical surface without using separate components such as a wall mounting adapter and a ceiling mounting adapter. The purpose is to provide.

[0007]

A security camera device according to the present invention is capable of adjusting a monitoring direction of the security camera, and includes a first support frame for supporting the security camera, and a first support frame. A second support frame rotatably supporting the support frame by a first rotation axis orthogonal to the optical axis of the security camera; and a second support frame orthogonal to the first rotation axis. A third support frame rotatably supported by the rotation shaft of the third support frame, and a fourth support frame rotatably supporting the third support frame by a third rotation shaft orthogonal to the second rotation shaft. It is provided.

With this configuration, the first to third supporting frames are respectively rotated about the first to third rotating shafts, so that the first to third supporting frames (mounting surfaces) are rotated. The direction of the support frame is adjusted, and the monitoring direction of the security camera supported by the first support frame can be adjusted three-dimensionally.

For example, when the camera is mounted on a vertical surface such as a wall, the first support frame is rotated about the first rotation axis with respect to the second support frame, and the vertical direction of the security camera is adjusted. Then, the direction of the security camera in the left-right direction is adjusted by rotating the second support frame about the second rotation axis with respect to the third support frame. Then, as a result, the vertical and horizontal directions of the security camera (first support frame) are adjusted. On the other hand, when mounting on a horizontal surface such as a ceiling surface or a tabletop, the first support frame is attached to the first support frame with respect to the second support frame.
, The vertical direction of the security camera is adjusted. Then, the third support frame is rotated about the third rotation axis with respect to the fourth support frame, and the horizontal direction of the security camera is adjusted. Then, as a result, the vertical and horizontal directions of the security camera (first support frame) are adjusted.

[0010] As described above, regardless of whether it is mounted on a vertical plane or a horizontal plane, a necessary rotation axis is selected and the support frame is rotated only about the rotation axis.
It is possible to adjust the monitoring direction of the security camera in the mounted state in the up-down direction and the left-right direction while capturing the image with the correct vertical image.

In this case, the second rotation shaft not used when mounted on a vertical surface or the one rotation shaft not used when mounted on a horizontal surface is locked to prevent erroneous operation. A first engaged portion provided on a support frame, and a second engaged portion of the second supported frame which is removably engaged with the first engaged portion provided on the third support frame. A first engagement portion for restricting rotation about the second rotation shaft, or a second engagement portion provided on the third support frame and the fourth engagement portion; A second engagement portion provided on the frame to removably engage with the second engaged portion to regulate rotation of the third support frame about the third rotation axis. It is desirable to do so.

[0012] The first and second engaged portions may be engagement recesses, and the first and second engagement portions may be engaged with the engagement recesses in a detachable manner. With such a configuration, the rotation of the support frame about the rotating shaft, which is not required, is restricted by a simple structure in which the engaging protrusion is engaged with the engaging concave portion.

With this structure, the security camera can be mounted on either a vertical plane or a horizontal plane with a simple structure without increasing the number of parts, and the vertical and horizontal directions of the security camera can be adjusted. A security camera device having a compact structure that can be realized is realized.

Further, it is preferable that a light-transmitting cover member which is detachably attached to the fourth support frame and covers the security camera and the first to third support frames is provided. Here, “transmittable” means that it is possible to shoot with a security camera. Because it is less desirable for security cameras to be directly visible,
Colored and transparent ones are desirable.

With this configuration, by covering the security camera with the translucent cover member, it is possible to protect the security camera while maintaining a state in which the security camera is not directly visible from the outside and can photograph.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

The camera case 3 is housed in a rotating frame 4 which is a second supporting frame having a rectangular horizontal cross section, and is rotatably supported about a first rotating axis R1 orthogonal to the optical axis of the security camera 2. ing. Therefore, by rotating the camera case 3 about the rotation axis R1, the vertical direction of the security camera 2 can be adjusted. The camera case 3 is prevented from rotating carelessly after the direction of the security camera 2 is adjusted by the frictional force of the rotating portion of the camera case 3 with respect to the rotating frame 4.

The rotary frame 4 is rotatably supported by a rotary table 5 as a third support frame so as to be rotatable about a second rotary axis R2 orthogonal to the first rotary axis R1. That is, the turntable 5 includes a circular base plate 5a and a pair of support bracket portions 5b, 5b erected from the base plate 5a.
Therefore, the rotating frame 4 is rotatably supported between the support bracket portions 5b. Specifically, as shown in FIG. 2, a rotation shaft 4a protruding from the rotation frame 4 is rotatably inserted into a through hole 5c of the support bracket 5b. Then, a first washer 6 having a diameter larger than that of the through hole 5c is attached and fixed to the end of the rotating shaft portion 4a from outside the support bracket portion 5b with a first screw 7. 4 is rotatably attached to the turntable 5 (support bracket part 5b).

Further, the base 5a of the turntable 5
It is arranged in the concave portion 9a of the main body case 9 and is rotatably supported on a third rotation axis R3 orthogonal to the second rotation axis R2. Specifically, as shown in FIG. 2, the rotating shaft 5 protruding from the base plate 5a of the rotating base 5 is provided.
d is rotatably inserted from one side of the center hole 9b of the main body case 9 to the middle thereof. On the other hand, from the other side of the center hole 9b of the main body case 9, a rotating shaft portion 10b protruding from the large-diameter flange portion 10a of the second washer 10 is rotatably inserted into the center hole 9b. And the second
The second washer 10 is attached and fixed to the turntable 5 with the screw 11 of the present invention, and the turntable 5 is rotatable with respect to the main body case 9.

Here, the main body case 9 is composed of an upper case 9A to which the turntable 5 is attached and a lower case 9B to be attached to a mounting surface such as a ceiling surface. The camera signal line 2a of the security camera 2 is connected to the base 5a of the turntable 5 and the second
Through the central through holes 5h and 10c of the washer 10 described above. The signal line 2 a is led out of the main body case 9 as an output cable 12. The lower case 9B may be attached to the mounting surface by directly fixing the mounting surface to the mounting surface using screws or the like, or may be detachable from the mounting member fixed to the mounting surface. You may make it lock. Further, the camera case 3,
The rotating frame 4, the rotating base 5, and the main body case 9 are formed of a synthetic resin.

A cover member 13 is fitted into the concave portion 9a of the main body case 9, and in this fitted state, the cover member 13 covers the security camera 2, the rotary frame 4, the turntable 5, and the like. It has become. On the inner peripheral wall surface of the concave portion 9a of the main body case 9 (upper case 9A), engaging projections (not shown) are formed at four locations in the circumferential direction, while the lower peripheral edge of the cover member 13 is provided with the engaging projections. Notches 13a are formed at four locations in the circumferential direction corresponding to the projections. And
By fitting the cover member 13 into the concave portion 9a of the main body case 9 and rotating the cover member 13 in a specific direction, the notch portion 13a of the cover member 1 side 3 is detachably engaged with the engaging convex portion on the main body case 9 side. In this case, the cover member 13 is configured to be attached to the main body case 9. The cover member 13 is formed of, for example, a transparent material colored black, and the security camera 2 covered by the cover member 13 cannot be directly viewed from the outside.

Then, as shown in FIG.
A first engaging recess 4b, which is a first engaged portion, is formed at an intermediate point in the width direction of the outer surface on the support bracket portion 5b side. On the other hand, the support bracket 5b of the turntable 5
The base piece 5 has a support piece 5 having a notch in the middle part in the width direction and a base end connected to the base board 5a.
The first engaging projection 5f is provided on the inner surface of the support piece 5e on the rotating frame 4 side so as to be detachably engaged with the engaging recess 4b. Therefore, the rotating frame 4 is
About the rotation axis R2, and the support piece 5 on the turntable 5 side.
e, using the elasticity of the synthetic resin itself,
By elastically engaging f with the engagement concave portion 4b, the rotation of the rotary frame 4 about the second rotation axis R2 is regulated by their engagement relationship.

Similarly, on the outer surface of the base plate 5a of the turntable 5 on the side of the main body case 9, a second engaged portion, which is a second engaged portion, is provided.
5g, the upper case 9A of the main body case 9 is partially cut out so that the base end is connected to the upper case 9A and the center end is a free end. The supporting piece 9d is formed, and a second engaging projection 9e is formed on a side surface of the supporting piece 9d on the turntable 5 side so as to removably engage with the second engaging recess 5g. Therefore, by rotating the turntable 5 about the third rotation axis R3 and utilizing the elasticity of the synthetic resin to elastically engage the engagement protrusion 9e with the engagement recess 5g, the third rotation is performed. The rotation of the turntable 5 about the axis R3 is regulated.

The basic system of the security camera device 1 is as follows:
It is configured as shown in FIG. That is, the output cable 12 led out from the security camera device 1 is appropriately attached and fixed by a stapler 21 (or a cord clip) and connected to the adapter unit 22. The adapter unit 22 is connected to a power supply 24 via a power cord 23 and to a video tape recorder 27 and a home television 28 as a monitor via video cords 25 and 26, respectively.

Therefore, if the power switch of the adapter unit 22 is turned on, the video taken by the security camera 2 can be simultaneously recorded on the video tape recorder 27 while being viewed on the home television 28.

In the security camera device 1, a mounting place is selected so that a place or a range to be monitored can be photographed reliably. When the security camera apparatus 1 is actually mounted, as shown in FIG. The case where the camera is mounted on a horizontal surface such as the ceiling surface F2 or the tabletop surface F3 differs in the direction adjustment of the monitoring direction by the security camera 2 in the mounted state. (When mounting on a vertical surface such as a wall) Camera case 3
Is rotated about the first rotation axis R1, the vertical direction of the security camera 2 is adjusted, and then the rotation frame 4 supporting the camera case 3 is rotated about the second rotation axis R2, and the security camera 2 is rotated. Adjust the horizontal direction of the.

At this time, when the second engaging projection 9e is engaged with the second engaging recess 5g, the third rotating shaft R
By restricting the rotation of the security camera 2 about 3, the erroneous operation of rotating about the third rotation axis R3 is prevented. That is, it is possible to adjust the monitoring direction of the security camera 2 in the up, down, left, and right directions while photographing the image with the correct vertical image. The second engagement projection 9
e is engaged with the second engagement recess 5g, the second rotation axis R2 is in a vertical direction, and the first rotation axis R1 is in a horizontal state so that the vertical direction of the security camera 2 can be adjusted. It has become. (When the camera case 3 is mounted on a horizontal surface such as a ceiling surface or a table top) The camera case 3 is rotated about the first rotation axis R1 to adjust the vertical direction of the security camera 2, and
Is supported by a rotary frame R via a rotary frame 4.
3 to adjust the horizontal direction of the security camera 2.

At this time, the first engaging projection 5f is engaged with the first engaging recess 4b, and the rotating frame 4 is moved to the second rotating shaft R2.
By regulating the rotation of the security camera 2 about
Erroneous operation of rotating about the rotation axis R2 is prevented. The first engaging projection 5f is connected to the first engaging recess 4
In the state where the security camera 2 is engaged, the second rotation axis R2 is in a horizontal direction, and the first rotation axis R1 is also in a horizontal state so that the vertical direction of the security camera 2 can be adjusted.

In the above embodiment, the engagement projection 5
The rotation of the rotary frame 4 and the turntable 5 is reliably restricted by the engagement relationship between the f and 9e and the engagement recesses 4b and 5g, so that the unnecessary rotation shaft R2 or R3 cannot be rotated to prevent erroneous operation. Although the present invention is not limited to this, the present invention is not limited to this. The portion provided with the engaging convex portion and the engaging concave portion may be reversed from the above embodiment, The same effect can be obtained even if the rotation is not performed by the frictional force in the rotating portion of the rotating frame or the rotating table without using the engaging relationship with the engaging recess. This is the security camera device 1
After the adjustment of the monitoring direction by the security camera 2 is completed, once it is attached, it is hardly adjusted again, so that it does not touch any of the support frames again, and the holding force due to the frictional force does not occur. This is because it is thought that it can withstand just enough. In addition, when the camera is actually attached, if the direction of the security camera 2 is adjusted while watching the image on the monitor, the vertical direction of the image can be adjusted without being particularly conscious of the first to third rotation axes R1 to R3. Because it is possible to adjust the direction up, down, left and right while shooting with the correct normal image, from this point as well, the rotation of the rotating frame and the turntable is reliably regulated by the engagement relationship between the engaging projection and the engaging recess. This is because there is no need to keep it.
