Abstract
A system and method of use relating to a hidden motorized system for use in windows that can reliability and consistently open and close the window via remote operation. Specifically, a motorized system is disposed inside a window in a manner without requiring unsightly modifications to the window. The motorized system can be controlled via wireless remote or wired remote switch. The entire system fits within a conventional window, such as a single or double hung window, in a manner that is hidden from view, thereby keeping the conventional ornamental look of the window.
Claims20
A motorized system for opening and closing a window, the system comprising:
- a motor, disposed inside a rail of a window sash of a window, comprising a drive shaft, disposed within and configured for mounting inside the rail of the window sash of the window;
- at least one main shaft configured for mounting inside the rail of the window sash and mechanically coupled with the drive shaft when in operable configuration;
- a gear disposed at a first end of the main shaft, distal from the motor;
- a corresponding gear receiver configured for mounting along the window channel of the window frame within which the window sash is slidably mounted, wherein the gear receiver meshes with the gear;
- a hidden balance system comprising a pulley and cable in combination with a tension spring, wherein when the window sash is lowered to a fully closed position, the cable is in tension and pulls on the tension spring, extending the tension spring, and wherein when the window is fully closed, the spring applies a force to the window sash via the cable, lessening a force required to move the window sash upward;
- wherein when mounted inside the window in operable configuration, the motor comprising the drive shaft moves the window along infinitely variable positions between open and closed.
A method, comprising:
- using a remote control device, sending a signal to a wireless receiver disposed in communication with a motorized system disposed and mounted inside non-glass components of a window sash, the signal indicating a command to the motorized system to move the window to a position ranging between and including fully open and fully closed positions;
- the motorized system receiving the signal and activating a motor to implement the received command;
- the window moving to the position commanded.
A double-hung window, comprising:
- a window sash slidably coupled with a window channel of a window frame;
- a motor comprising a drive shaft, wherein the motor and the drive shaft are mounted inside a rail of the window sash;
- a power source mounted inside the window sash in electrical communication with the motor;
- at least one main shaft mounted inside the rail of the window sash and mechanically coupled with the drive shaft when in operable configuration;
- a race or pinion gear disposed at a first end of the main shaft, distal from the motor;
- a gear rack mounted along the window channel of the window frame within which the window sash is slidably mounted, wherein the race or pinion gear meshes with the gear rack.
