## Abstract

An RF-remote control, retrofitted, self-contained, automatic window opener is provided for casement windows or the like which includes a housing having a DC motor therein which has a power shaft extending therefrom. The DC motor is powered by a battery source contained within the housing. The power shaft of the DC motor is selectively removably secured to the drive shaft of a conventional casement window opener mechanism so that the DC motor may rotate the drive shaft in either direction to open or close the sash of the casement window. The window opener of this invention is mounted within a housing which has anti-rotation members selectively adjustably extending therefrom which engage the window frame to prevent rotation of the unit when the motor is activated. The unit includes an electrical circuit which has an RF receiver associated therewith which is controllable by a remote RF transmitter to enable a person to remotely control the opening and closing of a casement window.

## Claims

### Claim 1

In combination with a casement window including a window sash movably mounted in a window frame with the window sash being movable between open and closed positions by a conventional opener mechanism including a drive shaft protruding from the opener mechanism, comprising:
a housing having a DC motor mounted therein which has a selectively reversible power shaft protruding from said housing which is powered by a battery source;
said power shaft adapted to be connected to the drive shaft of the opener mechanism whereby the window sash may be moved between its open and closed positions;
an electrical circuit in said housing for controlling the operation of said motor;
a RF receiver associated with said circuit;
and a remote RF transmitter which is capable of sending RF signals to said RF receiver to remotely open and close the window sash.

### Claim 2 (depends on 1)

The combination of claim 1 wherein said housing has a plurality of anti-rotation members extending therefrom for engagement with the window frame.

### Claim 3 (depends on 2)

The combination of claim 2 wherein said anti-rotation members are length adjustable.

### Claim 4 (depends on 1)

The combination of claim 1 wherein said housing comprises at least a pair of hollow housing members which are selectively secured together.
