  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing an embodiment of an embedded bracket mechanism of a surveillance video camera according to the present invention. 1A is a view of the embedded bracket mechanism of the surveillance video camera as viewed obliquely from above, FIG. 1B is a view as viewed from a different angle on the upper side, and FIG. Each figure is shown. The embedded metal fitting is composed of a main body 1 and a slide 2. The main body 1 mainly has a mechanism for fixing to a ceiling or a wall and a role for holding the slide portion 2. In order to fix to a ceiling, a wall, etc., the hole which can insert the main-body part 1 first is made in a ceiling, a wall, etc., and an embedded metal fitting is inserted there. At this time, the size of the hole is set such that the main body 1 can be inserted but the sandwiched base 1d cannot be inserted. Next, when the sandwiching height adjusting screw portion 1g is rotated, the sandwiching blade portion 1e attached to the sandwiching height adjusting screw support portion 1b rotates until it hits the sandwiching blade stopper portion 1c. Even after the sandwiching blade portion 1e hits the sandwiching blade stopper portion 1c, when the sandwiching height adjusting screw portion 1g is turned, the sandwiching blade portion 1e gradually lowers in the direction of the sandwiching base portion 1d, and the sandwiching base is placed. This is a mechanism for sandwiching a ceiling, a wall or the like between the part 1d. At this time, the pinching blade portion 1e is subjected to a pressing force against the pinching blade stopper portion 1c by the blade rotation acceleration spring portion 1j (FIG. 4B). Therefore, when the pinching height adjustment screw portion 1g is turned. Since the sandwiching blade portion 1e immediately and reliably contacts the sandwiching blade stopper portion 1c, there is an effect of shortening the time for sandwiching the ceiling or the wall. The slide portion 2 is housed and fixed in the main body portion 1 by fixing the slide portion fixing portion 1f and the slide portion housing fixing screw hole portion 2c of the main body portion 1 with screws. When sliding and pulling out, if the above-mentioned fixing screw is removed and the slide part 2 is pulled down, the pull-out stop screw part 2b hits the pull-out stop receiving part 1a of the main body 1 and has an arbitrary length set in advance. It can be pulled out.

FIG. 2 is a view showing an embodiment in which the camera is installed in the embedded bracket mechanism of the surveillance video camera according to the present invention. FIG. 2A is a diagram in which a camera having a dome cover attached to the slide portion 2 is attached. FIG. 2B is a diagram in which the camera with the dome cover removed is attached to the slide portion 2. The camera to be installed is a camera that has a dome cover attachment / detachment mechanism on the side of the camera body, such as a tamper-proof purpose or a small camera that cannot secure a sufficient area to be screwed vertically to the camera body. . In order to attach and detach the dome cover 3a in a state where the camera unit 3 is fixed to the camera mounting screw hole 2a prepared on the slide unit 2 with a screw, the dome camera attaching / detaching mechanism unit 3b prepared on the side surface of the dome cover is attached to the camera unit. 3 by rotating the dome cover portion 3a in an arbitrary direction while being pushed into the interior. The angle of view is adjusted by adjusting the angle of view adjusting mechanism 3c with the dome cover 3a removed. At that time, the video output cable 4 (FIG. 3 (a)) is connected to the video output terminal section 3d and output to a monitor such as a TV prepared at hand so that the angle of view of the camera can be adjusted while checking the monitor video. It is possible to adjust.

  As described above, by using an embedded bracket with a slide mechanism, even if the camera body has a dome cover attachment / detachment mechanism on the side of the camera body, the embedded bracket can be removed after fixing the embedded bracket to the ceiling or wall. It is easy to adjust the angle of view using only the angle-of-view adjustment mechanism provided in the camera without moving it.

  FIG. 3 is a diagram showing an embodiment in which a video output cable is connected to a camera mounted on an embedded metal fitting. FIG. 3A is an example of a commercially available video output cable 4. In FIG. 3B, the video output cable 4 of FIG. 3A is connected to the video output terminal portion 3d of FIG. 2B in a state where the camera is attached to the embedded metal fitting and the slide portion 2 is pulled down. FIG. FIG.3 (c) is the figure which accommodated the slide part 2 with the state connected in FIG.3 (b). In particular, in a small dome camera, there is no space for providing the video output terminal portion 3d in a direction perpendicular to the surface such as the ceiling or the wall, and it is horizontal to the surface such as the ceiling or the wall as shown in FIG. Since there is a case where it has to be provided in the direction, a space is secured in advance so that the slide portion can be pulled out and stored in a state where the video output cable as shown in FIG. 3A is connected to the video output terminal portion 3d. Thus, similarly to the angle of view adjustment, it is easy to connect and disconnect the video output cable without removing or moving the embedded bracket after the embedded bracket is fixed to the ceiling or wall.

FIG. 4 is a view showing an embodiment in which the sandwiching blade portion 1e is accommodated. FIG. 4A is an enlarged view of the main body 1 around the sandwiching blade 1e. FIG. 4B is an enlarged view of the sandwiching blade portion 1e itself. If it is necessary to remove the embedded bracket from the ceiling or wall for reasons such as canceling or replacing the camera, remove the screw that secured the camera in the camera mounting screw hole 2a, and then pinch the camera. By turning the height adjusting screw portion 1g in the loosening direction, the force sandwiching the ceiling or wall by the sandwiching blade portion 1e and the sandwiching base portion 1d is weakened, and the embedded metal fitting main body portion 1 is removed. At this time, since the force applied to the sandwiching blade stopper portion 1c by the blade rotation acceleration spring portion 1j is applied to the sandwiching blade portion 1e, it takes time to remove it only by loosening the sandwiching height adjusting screw portion 1g. . Therefore, a mechanism for facilitating the removal work is provided by providing a mechanism for forcibly storing the sandwiching blade portion 1e. First, a space enough to insert a human finger is left on the side of the main body 1 on the side where the sandwiching blade 1e is stored. Then, a finger is inserted, the finger is hooked on the fingertip hooking portion 1n, and pulled while being rotated in the direction of the sandwiching blade storing lock portion 1h.
Next, the blade storage lock claw portion 1k is hooked on the sandwiched blade storage lock portion 1h to be securely fixed. By doing so, the pinching can be released and the removal time can be shortened even when the pinching height adjusting screw portion 1g is slightly loosened. The blade storage lock claw portion 1k is provided along the shape of the blade storage lock claw portion 1k by providing the blade storage lock claw portion 1m with a slit, and the blade storage lock portion 1h. When the hook is hooked or when the blade storage lock claw portion 1k is removed from the sandwiched blade storage lock portion 1h, it can be attached and detached without any problem even if some stress is applied.
