US 5,826,377 A · Remotely-driven power window

Abstract

A mechanism for the powered opening and closing of household panels such as windows and doors comprises a worm drive screw, small enough to be mounted within and along the upper track of a sliding panel. A nut threaded on the drive screw moves axially along the screw when the screw is rotated. Motion of the nut is transmitted to the panel by means of a coupling bolt, slidingly mounted within a cavity in the top of the panel. The bolt slides up to engage the nut for powered operation, and slides down to disengage from the nut during manual operation. The position of the bolt can be secured through locking means. A resilient, dielectric transmission accouplement between the drive screw and the motor provides electrical and vibrational isolation, and scalability. A second extendible bolt mounted on an opposite end of the frame hinders pitch deflection of the panel during powered operation. Worm gearing and a solenoid based brake locks the motor and the position of the nut when no power is applied.
