Mechanical Window Opener for Double Hung Windows

By Watson, David B.; Mollendorf, Joseph C.; NSF 2007 Engineering Senior Design Projects to Aid Persons With Disabilities, pp. 200-201
Publication Date: 2010

Description of an electrically powered system that allows people with reduced arm strength and motor control to easily open double hung windows. Designed by an engineering student at the State University of New York at Buffalo, the window opener is designed as an aftermarket product, which allows the user to mount the unit directly to a preinstalled window. The window opener comprises an acrylic case which is sectioned internally to hold the mechanical components. The entire unit mounts to the window frame via two lag screws. An angle bracket is fixed to the window and then connected to the unit’s connecting bar, which in turn moves the window when the motor is operating. A power converter included with the system plugs into a standard wall outlet and connects to the port on the bottom of the unit. The user can then operate the window by manually pressing the Up or Down buttons on the face of the device. When the unit is energized, the internal motor turns a lead screw on which the connecting bar is threaded. The connecting bar travels up or down the lead screw depending on the motor direction and carries the window with it. A future addition planned for the window opener is a remote control device.
