Abstract
Abstract Overhead doors operating apparatus uses a single motor power unit to operate a selected one of a plurality of overhead doors through a selectively energized coupling, such as an electromagnetic clutch, or if desired, all of the doors in unison by energizing all the couplings. Thus only one motor power unit, instead of a power unit for each door, is needed to operate selectively one or more of the doors.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
Apparatus for selectively operating a plurality of doors mounted for overhead opening comprising a motor power unit coupled to a mechanical drive means, switching means responsive to actuation for energizing the motor power unit, drive means connected to each door for opening or closing the door, a like plurality of normally inoperative electrically actuated coupling means having input and output members, an output member of each one of the coupling means connected to a corresponding one of the drive means, the mechanical drive means connected to the input members of the electrically actuating coupling means, and said switching means that energizes the motor power unit also electrically actuating one or more of the coupling means to couple together the input and output members and cause the power unit to operate the mechanical drive means for opening and closing one or more of the doors.
Claim 2
Dependent Claim
144 words
Apparatus for selectively operating a plurality of doors mounted for overhead opening comprising a motor power unit coupled to a mechanical drive means, switching means responsive to actuation for energizing the motor power unit, drive means connected to each door for opening or closing the door, a like plurality of normally inoperative electrically actuated coupling means having input and output members, an output member of each one of the coupling means connected to a corresponding one of the drive means, the mechanical drive means connected to the input members of the electrically actuating coupling means, and said switching means that energizes the motor power unit also electrically actuating one or more of the coupling means to couple together the input and output members and cause the power unit to operate the mechanical drive means for opening and closing one or more of the doors.
Claim 3
Dependent Claim
15 words
Apparatus as defined in claim 1, wherein one of the doors is opened or closed.
Claim 4
Dependent Claim
18 words
Apparatus as defined in claim 1, wherein one or all of the doors may be opened or closed.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
153 words
Apparatus for selectively operating a plurality of remotely operated door adjacently mounted for overhead opening comprising a motor power unit coupled to a mechanical drive means, radio receiver means responsive to coded radio signals for energizing the motor power unit, drive means connected to each door for opening or closing the door, a like plurality of normally inoperative electrically actuated coupling means having input and output members, an output member of each one of the coupling means connected to a corresponding one of the drive means, the mechanical drive means connected to the input members of the electrically actuated coupling means, and said radio receiver means also responsive to said coded radio signals for electrically actuating one or more of the coupling means to couple together the input and output members and cause the motor power unit to operate the mechanical drive means for opening and closing one or more of the doors.
Claim 8
Dependent Claim
153 words
Apparatus for selectively operating a plurality of remotely operated door adjacently mounted for overhead opening comprising a motor power unit coupled to a mechanical drive means, radio receiver means responsive to coded radio signals for energizing the motor power unit, drive means connected to each door for opening or closing the door, a like plurality of normally inoperative electrically actuated coupling means having input and output members, an output member of each one of the coupling means connected to a corresponding one of the drive means, the mechanical drive means connected to the input members of the electrically actuated coupling means, and said radio receiver means also responsive to said coded radio signals for electrically actuating one or more of the coupling means to couple together the input and output members and cause the motor power unit to operate the mechanical drive means for opening and closing one or more of the doors.
