Abstract
A slidable pane power window assembly for mounting in the rear window of truck cabs is disclosed. The assembly comprises a frame dimensioned to fit in the rear window opening of a truck cab and fitted with one or more fixed and slidable window panes. A slidable pane is moved horizontally into an opened and closed position by a rack and pinion drive, wherein a rack affixed to the slidable pane is engaged by a pinion powered by a motor connected to the pinion via power transmission cable. Another embodiment uses a push-pull mechanism for operating the window.
Claims12
A power window replacement assembly for the rear window opening of a truck cab or the like, comprising:
- a frame having at least two opposed sides and having substantially the same shape as the window opening;
- three window panes housed within the frame, wherein a first pane is fixedly mounted in the frame to form the first side of the frame, a second pane is fixedly mounted to form part of the second side of the frame and a third sliding pane is mounted in the frame, the third sliding pane being adapted to slide at least partially past the first fixed pane in a first horizontal direction to a fully opened position and to slide in a second horizontal direction to a closed position wherein when the sliding pane is moved to its fully closed position, the three panes filling the frame when the sliding pane is in the closed position;
- an electrical motor;
- an engagement means affixed to the sliding pane;
- and
- a drive engagement means coupled to the motor and mounted at least partially in the frame and contacting the engagement means for moving the engagement means in the first and second horizontal directions.
A power window replacement assembly for the rear window opening of a truck cab or the like having an electrical power system, comprising:
- a frame having substantially the same shape as the window opening;
- a pane being slidably disposed with the frame to slide between an opened and closed position in the frame;
- an electric motor adapted to be coupled to the power system of the truck cab, the motor adapted to cause movement in a first direction and in a reverse direction;
- and
- a transmission cable coupled between the motor and the sliding window pane to move the pane within the frame, the transmission cable comprising:
- an outer hollow cable positioned between the motor and the pane, said cable being made of teflon;
- an interior cable having two opposed ends, said interior cable being slidably disposed at least partially within the outer cable, the first end being affixed to the window pane, said interior cable being made of nylon;
- and
- transmission drive means affixed to the motor and the second end of the interior cable for sliding the interior cable in a first direction and in a reverse direction depending upon the direction of movement in the motor, wherein the window is caused to slide between the opened and closed positions said transmission drive means including means for retracting a portion of the interior cable into the transmission drive means wherein the sliding window pane is moved to the opened position and for pushing out a portion of the interior cable from the transmission drive means wherein the sliding window pane is moved to the closed position said transmission drive means further including
- a chamber mounted in a fixed position relative to the motor,
- a cross-member held in a fixed position in the chamber, and
- a rotating disc having a flat surface adjacent to the flat cross-member and coupled to the motor, wherein a first portion of the interior cable is positioned in a contacting relationship with both the rotating disc and the flat cross-member such that when the rotating disc rotates in a first direction, more of the interior cable is retracted into the chamber thereby moving the slidable window pane towards the fully opened position and when the rotating disc rotates in the opposite direction, more of the interior cable is pushed from the chamber, thereby moving the window towards the closed position.
