Abstract

A remote control system for window blinds including a control unit provided for each of a plurality of blinds which are opened and closed freely, each blind further including rotatable slats. The control unit is provided with a signal receiver, and through the use of a transmitter, which is provided separately, the control unit controls the individual blind as well as slats thereof, and a plurality of control units can be successively actuated so that two or more blinds and the slats thereof can be controlled at the same time from a distance. By means of this remote control system, a centralized control of the blinds can be performed without requiring a special control board, and erroneous operation can be avoided as blind operation is done after the blind number is designated. When the blind operation is completed, the system is automatically reset for the next operation command.

Claims8

Dependent claims

A remote control blind system comprising:

a plurality of blinds which can be freely opened and closed;
a plurality of control units provided for each of said blinds, for independently opening and closing each of said blinds;
receiving means for receiving and processing radio signals and for transmitting said signals to said control units;
and
transmitting means provided separately from said receiving means, for transmitting said radio signals;
each of said control units at least comprising:
means for storing a blind number to specify said blind;
means for comparing a signal of said stored blind number with a designation signal of the blind number that was received and processed, from said radio signal and for transmitting an agreement signal of the blind number when said signals agree;
a holding type open/close gate which is set by said agreement signal and which transmits an operation signal of the blind to a drive means for opening and closing the blind;
a retriggerable timer which is triggered by the blind operation signal and which transmits a stop signal of the blind operation when said timer is not retriggered for a predetermined period of time;
and
reset signal generating means which resets the holding type open/close gate when the stop signal of the blind operation is transmitted.

A remote control blind system comprising:

a plurality of blinds which have rotatable slats and which can be freely opened and closed;
a plurality of control units provided for each of said blinds, for independently opening and closing each of said blinds and for independently rotating said slats of each of said blinds;
receiving means for receiving and processing radio signals and for transmitting said signals to said control units;
and
transmitting means provided separately from said receiving means, for transmitting said radio signals;
each of said control units at least comprising:
means for storing a blind number to specify said blind;
means for comparing a signal of said stored blind number with a designation signal of the blind number that was received and processed, from said radio signal and for transmitting an agreement signal of the blind number when said signals agree;
a holding type open/close gate which is set by said agreement signal and which transmits an operation signal of the blind to a drive means for opening and closing the blind;
a holding type open/close gate which is set by said agreement signal and which transmits an operation signal of the slats to a drive means for rotating the slats;
a retriggerable timer which is triggered by the blind or slats operation signal and which transmits a stop signal of the blind operation when said timer is not retriggered for a predetermined period of time;
and
reset signal generating means which resets the holding type open/close gate when the stop signal of the blind operation is transmitted.
