Abstract

A remote control for the wireless transmission of control commands from a ansmitter to at least one receiver, with an encoding device provided in the transmitter which effects an encoding of the control commands to be transmitted. In a first transmitter different codes are stored for each receiver. Via a data link between the first transmitter and a second transmitter, which data link can be made temporarily, at least one code is transferred from the encoding device of the first transmitter to the encoding device of the second transmitter.

Claims

1. A remote control for wireless transmission of control commands from a transmitter to a plurality of receivers, in particular for the remote control of several garage doors with an encoding device provided in a first transmitter which effects encoding of control commands to be transmitted,

the transmitter for the remote control being a second transmitter,

wherein in said first transmitter, a different code is stored for each said receiver,

a data link is arranged to be generated temporarily between the first transmitter and the second transmitter in such a way that at least one code is transferred from the encoding device of the first transmitter to an encoding device of the second transmitter,

at least one universal transmitter is provided as the first transmitter and several user-configurable transmitters are provided as the second transmitter, with a code being arranged to be transferred to at least one of the user-configurable transmitters only by the universal transmitter.

2. A remote control in accordance with claim 1, wherein the corresponding codes are stored in an unalterable manner in the universal transmitter during its manufacture.

3. A remote control in accordance with claim 1, wherein in the universal transmitter, corresponding codes are arranged to be set individually.

4. A remote control in accordance with claim 3, comprising an integrated random generator arranged to be actuated by a hidden button for individually setting the corresponding codes in the universal transmitter.

5. A remote control in accordance with claim 1, wherein by means of the universal transmitter, a receiver can be initialized by a code stored in the universal transmitter being transferred to and stored in the relevant receiver.

6. A remote control in accordance with claim 1, wherein a certain button on the universal transmitter is allocated to each of the codes stored in the encoding device in the universal transmitter and arranged such that when the button is pressed, transmission of the control commands encoded by the corresponding code is performed to the requisite user-configurable transmitter.

7. A remote control in accordance with claim 1, wherein exactly one button is provided on the user-configurable transmitter such that when this button is pressed repeatedly, transmission of several sequences of control commands is performed with number of sequences corresponding to number of codes stored in the encoding device of the user-configurable transmitter and with each sequence being encoded with a different code in each case.

8. The combination in accordance with claim 1, wherein a display unit is provided on the first transmitter which display unit displays the current status of the first transmitter.

9. The combination in accordance with claim 1, wherein the data link between the first transmitter and the second transmitter is performed by an electrical line connection.

10. The combination in accordance with claim 1, wherein the data link between the first transmitter and the second transmitter is performed by an opto-electronic connection or a radio connection.

11. The combination of claim 1, wherein

only one code is allocated to each receiver,

encoding of the second transmitter is arranged to be spatially independent of the receivers, and

the second transmitter is encoded by at least affirmative operation of the first transmitter to ensure security of the entire system.

12. The combination of claim 1, comprising a plurality of buttons situated upon the first transmitter, each said button being arranged to transfer a respective code upon being depressed to the second transmitter,

respective codes being stored in said receivers on said garage door corresponding to said plurality of buttons on said first transmitter,

said second transmitter also comprising a plurality of buttons;

means initializing each of said receivers by depressing a certain button on said first transmitter to transmit said respective code to said receiver, whereby said respective garage door can only be opened by transmission of said respective code, and

means for transferring said respective code to said second transmitter by simultaneously pressing said respective buttons on said first and second transmitters to transfer respective codes from first said transmitter to said second transmitter,

whereby operation of said respective garage doors by depressing said respective buttons on said second transmitter can be carried out in a secure manner.

13. The combination of claim 1, comprising

a plurality of buttons situated on said first transmitter and arranged to selectively transfer a code to a respective one of said receivers upon being depressed,

respective codes stored in said receivers on said garage doors corresponding to said plurality of buttons on said first transmitter,

a further single control button situated upon said first transmitter and said second transmitter comprising just a single button,

means for initializing each said receiver by depressing a certain selective button on said first transmitter to transmit said respective code to said receiver, whereby said respective garage door can only be opened by transmission of said respective code, and

means for transferring said respective code to said second transmitter by simultaneously pressing said respective selective button and said control button upon said first transmitter and said single button on said second transmitter to transfer said respective code to said second transmitter,

whereby operation of said respective garage door by depressing said respective single button on said second transmitter an appropriate sequence, can be carried out.
