Abstract

A garage door power module is provided with the capability of operating over a number of different operating frequencies by configuring a power module chassis with a receptacle for receiving radio receivers where each of the receivers is adapted to receive one of the frequencies. The receptacle located near one edge of the chassis and is configured with a planar surface and support members that permit the receivers to be slidably inserted and removed from the receptacle. In addition the radio receiver is equipped with a plug connector and the receptacle is equipped with a socket for receiving the plug connector in order to transmit radio control signals from the receiver to logic control circuits in the power module.

Claims

1. A method for changing the operating frequency of a garage door opener that includes a power module having a chassis that includes a motor support and logic circuitry, a housing secured over the chassis and a first radio receiver having a first operating frequency comprising the steps of:

removing said housing from said chassis;

removing said first radio receiver from a receptacle configured in said chassis;

insert a second radio receiver having an external antenna and a second operating frequency into said receptacle;

plugging a plug connector on said second radio receiver into a plug-in-socket, operatively coupled to said logic circuitry, located in said receptacle;

placing said antenna between the housing and the chassis; and

securing the housing to the chassis with said antenna enclosed within said housing.

2. The method of claim 1 wherein said step of inserting said second radio receiver includes the step of engaging a retaining member configured on said second radio receiver with an indentation configured in said receptacle.

3. The method of claim 1 wherein said first operating frequency is 40 MHz.

4. The method of claim 3 wherein said second operating frequency is 433 MHz.

5. The method of claim 1 wherein said step of inserting said second radio receiver includes sliding said second radio receiver along a planar surface configured in said receptacle.

6. The method of claim 1 wherein step of inserting said second radio receiver includes inserting said second radio receiver in said receptacle located along one edge of the chassis.

7. A garage door power module that includes a motor support and logic circuitry for controlling a motor comprising:

a chassis having a base member and including the motor support and the logic circuitry located on said base member;

a housing adapted to be secured to said chassis;

a plurality of radio receivers each including an external antenna and wherein each of said radio receivers has a different predetermined operating frequency; and

receiver means for slidably receiving and securing one of said radio receivers to said chassis such that its antenna is enclosed within said housing.

8. The module of claim 7 wherein said radio receivers include a connector and said receiver means includes connector means for electrically connecting said connector to the logic circuitry.

9. The module of claim 8 wherein said connector means includes a plug-in-socket for electrically connecting said connector to the logic circuitry.

10. The module of claim 7 wherein said receiver means includes retaining means for retaining said radio receivers within said chassis.

11. The module of claim 10 wherein said radio receivers include a projection and said retaining means includes an indentation for engaging said projection.

12. The module of claim 7 wherein said receiver means is located along one edge of said chassis.
