Abstract

A panel of a size to be inserted into a section of the hung framework of a suspended ceiling carries a housing, the lower portion of the housing projecting beneath the panel and comprising a tinted, partially transparent cylindrical sidewall closed at its lower end by a hinged, opaque cover. A rotatable bracket is mounted within the housing, and carries an opaque cylinder positioned within the partially transparent cylindrical sidewall, the cylinder having a window therein. A television monitoring camera is also mounted on the bracket, with its lens pointing through the window. A motor for operating the monitoring camera is mounted atop the housing, and the partially transparent cylindrical sidewall and the opaque cylinder cooperate to effectively shield the monitoring camera from view as it is panned over the premises.

Claims

1. An arrangement for mounting a monitoring camera on a ceiling, including:

a housing including upper and lower portions, said lower housing portion including a partially transparent, cylindrical sidewall;

means for mounting said housing on said ceiling, with at least said lower housing portion extending downwardly from said ceiling;

a rotatable drive shaft mounted to extend into said housing from the upper end thereof;

motor means connected with said drive shaft for effecting rotational movement thereof;

bracket means mounted on the lower end of said drive shaft, within said housing;

an opaque cylinder carried by said bracket means and received within said partially transparent cylindrical sidewall of said lower housing portion, said opaque cylinder having a window therein; and

said bracket means being adaptable to mount a monitoring camera within said opaque cylinder, with its lens aimed through said window,

said bracket means, said opaque cylinder and said camera being movable as a unit upon rotation of said drive shaft by said motor means, and said partially transparent lower cylindrical sidewall and said opaque cylinder concealing said camera from view.

2. An arrangement for mounting a monitoring camera as recited in claim 1, wherein said ceiling is a suspended ceiling including a hung framework made up of interconnected strips arranged in a rectangular pattern, and wherein said means for mounting said housing on said ceiling includes:

a mounting panel receivable in one of the sections of said hung framework, said housing being carried by said mounting panel, with at least said partially transparent, cylindrical sidewall of said lower housing portion projecting downwardly from said mounting panel.

3. An arrangement for mounting a monitoring camera as recited in claim 2, wherein the upper portion of said housing extends above said mounting panel, and wherein said motor means is mounted on the upper end of said housing.

4. An arrangement for mounting a monitoring camera as recited in claim 3, including additionally:

a mounting plate secured to the top of said housing; and

hanger means for connecting said mounting plate to ceiling structure positioned thereabove;

said motor means being carried by said mounting plate.

5. An arrangement for mounting a monitoring camera as recited in claim 1, wherein said ceiling is a structural ceiling, and wherein said means for mounting said housing includes fastener means for securing the upper end of said housing to the undersurface of said structural ceiling, said arrangement further including:

a frusto-conical shade secured to the exterior of said housing at the upper end thereof, the vertical height of said shade being greater than the vertical height of the upper portion of said housing, whereby said shade is effective to shade and shield partially transparent, cylindrical sidewall of said lower housing portion.

6. An arrangement for mounting a monitoring camera as recited in claim 1, wherein the lower end of said housing is closed by a hinged cover, and including means for securing said hinged cover in a closed position.

7. An arrangement for mounting a monitoring camera as recited in claim 6, wherein said means for securing said hinged cover in a closed position includes:

at least one securing clip carried by said hinged cover at a point spaced from the hinge connecting it to said housing, said securing clip including a nose, and the lower edge of said cylindrical sidewall of said lower housing portion having a latch opening therein adapted to receive said securing clip nose when said cover is in a closed position, said cylindrical sidewall being resiliently bendable to allow for insertion and removal of said securing clip nose.

8. An arrangement for mounting a monitoring camera as recited in claim 1, wherein said partially transparent, cylindrical sidewall of said lower housing portion is tinted.

9. An arrangement for mounting a monitoring camera as recited in claim 1, wherein the exterior of said opaque cylinder is dark colored.

10. An arrangement for mounting a monitoring camera as recited in claim 1, wherein said bracket means includes:

an inverted U-shaped member, connected centrally of the base portion thereof to the lower end of said drive shaft, said opaque cylinder being connected to the depending legs of said U-shaped member;

an L-shaped support arm, one leg of said support arm being connected to said base portion of said U-shaped member, and the other leg thereof extending vertically downwardly; and

an L-shaped mounting arm, one leg of said mounting arm being secured to the downwardly extending leg of said support arm, and the other leg of said mounting arm extending horizontally and being adapted to support said monitoring camera,

said U-shaped member and said L-shaped support arm having spaced openings therein, whereby different monitoring cameras can be readily accommodated.
