| Inventor(s) | Flannery; Joe W. (Toronto, CA) |
| Abstract | A plurality of motors are affixed to opposite spaced parallel walls of a
room. A plurality of cable-type support members each has a first end
affixed to a false ceiling at a corresponding point thereof and a second
end affixed to a corresponding one of the motors. The false ceiling is
thus supported in parallel spaced relation with the ceiling of the room
and is selectively varied in its distance from the ceiling of the room by
operation of the motors. |

I claim:
1. A movable ceiling device for a room having a ceiling and a pair of
opposite spaced substantially parallel walls, said ceiling device
comprising
a false ceiling;
a plurality of brackets affixed to the opposite walls a close distance
beneath the ceiling in mutually spaced relation;
a plurality of motors above the false ceiling and mounted on the brackets;
a plurality of pulleys, each coupled to, and rotated in opposite directions
by, a corresponding one of the motors; and
a plurality of cable-type support members each having a first end affixed
to the false ceiling at a corresponding point thereof and a second end
affixed to a corresponding one of the pulleys in a manner whereby the
false ceiling is supported in substantially parallel spaced relation with
the ceiling of the room and is selectively varied in its distance from the
ceiling of the room by operation of the motors.
2. A movable ceiling device as claimed in claim 1, wherein the motors are
fractional horsepower electric motors having reversible directions of
rotation. |

DESCRIPTION OF THE INVENTION
The present invention relates to a movable ceiling device. More
particularly, the invention relates to a movable ceiling device for a room
having a ceiling and a pair of opposite spaced substantially parallel
walls.
Objects of the invention are to provide a movable ceiling device of simple
structure, which is inexpensive in manufacture, used with facility and
convenience, installable in new and existing structures with facility and
convenience, and functions efficiently, effectively, and reliably to
selectively vary a false ceiling in its distance from the ceiling of a
room.
In order that the invention may be readily carried into effect, it will now
be described with reference to the accompanying drawing, wherein:
FIG. 1 is a perspective view of an embodiment of the movable ceiling device
of the invention; and
FIG. 2 is a side view of the embodiment of FIG. 1.
The movable ceiling device of the invention is for a room having a ceiling
1 and a pair of opposite spaced substantially parallel walls 2 and 3.
The movable ceiling device of the invention comprises a false ceiling 4.
A plurality of motors 5, 6, 7 and 8 (FIG. 1) are affixed to the opposite
walls 2 and 3. The motors 5 to 8 are preferably fractional horsepower
electric motors having reversible directions of rotation.
A plurality of cable-type support members 9, 10, 11 and 12 (FIG. 1) are
provided. Each of the cable-type support members 9 to 12 has a first end
such as, for example, the first end 13 of the support member 9 (FIG. 2)
affixed to the false ceiling 4 at a corresponding point 14 thereof. Each
of the cable-type support members 9 to 12 has a second end, such as, for
example, the end 15 of the support member 9 (FIG. 2), affixed to a
corresponding one of the motors such as, for example, the motor 5 (FIG.
2). The support members 9 to 12 are affixed to the motors 5 to 8,
respectively, in a manner whereby the false ceiling 4 is supported in
substantially spaced relation with the ceiling 1 of the room and is
selectively varied in its distance D (FIG. 2) from the ceiling of the room
by operation of the motors.
Thus, when the motors 5 to 8 are rotated in one direction, they move the
false ceiling 4 upward, in the direction of an arrow 16 of FIG. 2. When
the motors 5 to 8 are rotated in the opposite direction, they move the
false ceiling 4 downward, in the direction of an arrow 17 of FIG. 2.
While the invention has been described by means of a specific example and
in a specific embodiment, I do not wish to be limited thereto, for obvious
modifications will occur to those skilled in the art without departing
from the spirit and scope of the invention.
