Claims
- 1. A window regulator positionable in a vehicle for independently raising and lowering a window pane, the window regulator providing the exclusive support and guidance for the window pane, comprising:
- a guide plate fixedly attachable to the vehicle and having a pair of generally parallel, substantially vertical ends;
- a pair of sliders, each slider being fixedly attachable to the window pane and slidably securable to a respective vertical end of the guide plate; and
- drive means attached to the guide plate and connected to the window pane at a point between the sliders so as to be operable to directly drive the window pane for raising and lowering the pane while the pane is being guided by the sliders sliding along the vertical ends of the guide plate.
- 2. A window regulator as claimed in claim 1, wherein the drive means comprises a bracket secured to the window pane at said point which substantially corresponds to a point right under the center of gravity of the window pane.
- 3. A window regulator as claimed in claim 1, wherein the guide plate is rectangular in shape.
- 4. A window regulator as claimed in claim 1, wherein the vertical ends of the guide plate each comprise a guide rail portion having an L-shaped cross section and each of the sliders has a bifurcated end portion for straddling a respective vertical end of the guide plate.
- 5. A window regulator as claimed in claim 1, wherein the drive unit comprises a winding drum journalled on the guide plate at a location intermediate upper and lower ends of the guide plate, a separate pulley journalled on the guide plate at respective upper and lower ends thereof, a movable bracket fixedly attached to the window pane, a wire having a portion fixedly attached to the movable bracket and means for rotating the winding drum.
- 6. A window regulator as claimed in claim 5, wherein the drive means further comprises an electric motor.
- 7. A window regulator positionable in a vehicle having no means for guiding a window pane, the window regulator for independently raising and lowering a window pane, comprising:
- a guide plate fixedly attachable to the vehicle and having a pair of generally parallel, substantially vertical ends;
- a pair of sliders, each slider being fixedly attachable to the window pane and slidably securable to a respective vertical end of the guide plate; and
- drive means attached to the guide plate and connected to the window pane at a point between the sliders so as to be operable to directly drive the window pane for raising and lowering the pane while the pane is being guided by the sliders sliding along the vertical ends of the guide plate.
- 8. An apparatus for a vehicle, comprising in combination:
- a window pane;
- a door attachable to the vehicle, the door having no structure for guiding the window pane as the window pane is raised or lowered relative to the door; and
- a window regulator comprising:
- a guide plate fixedly attachable to the door and having a pair of generally parallel, substantially vertical ends;
- a pair of sliders, each slider being fixedly attachable to the window pane, and slidably securable to a respective vertical end of the guide plate; and
- drive means attached to the guide plate and connected to the window pane at a point between the sliders so as to be operable to directly drive the window pane for raising and lowering the pane while the pane is being guided by the sliders sliding along the vertical ends of the guide plate.
