Abstract

A device for opening and closing a movable window of a motor vehicle, the movable window being movable relative to a fixed panel, from a closed position in which the movable window is positioned flush with the fixed panel, to an open position in which the movable window is moved parallel to the fixed panel. The device includes an assembly controlled from a handle mechanism supported by an edge of a frame secured to the movable window, such that starting from the closed position, actuating the handle a first time releases locking of the movable window then, secondly, brings the movable window out of its closed position, an edge of the window corresponding to the edge of the frame being moved relative to the fixed panel, to the position allowing sliding of the movable window.

First claim

The invention claimed is:

1. A device for opening and closing a movable window of a motor vehicle, the movable window configured to move with respect to a fixed panel, from a closed position, wherein the movable window is arranged flush with respect to the fixed panel, to an open position, wherein the movable window is moved parallel to the fixed panel, the device comprising:
an assembly, controlled from a handle mechanism attached to an edge of a frame secured to the movable window such that, starting from the closed position, actuation of the handle, in a first stage, unlocks the movable window once the handle reaches a threshold position and then, in a separate second stage after the first stage, further actuation of the handle leads the movable window out of the closed position, an edge of the window corresponding to the edge of the frame, being moved with respect to the fixed panel, toward a position allowing the movable window to slide.

2. The device as claimed in claim 1 , wherein the movable window, in a closed position, is immobilized by the handle mechanism.

3. The device as claimed in claim 2 , wherein the immobilization of the movable window is effected by rotation of a rod extending along the edge of the frame, the rod comprising, at ends thereof, means engaging with rails, attached to the fixed panel during sliding of the movable window.

4. The device as claimed in claim 3 , wherein the handle comprises a means engaging with a ring forming a cam, arranged on the rod, preventing rotation of the rod, until a threshold in actuation of the handle is reached.

5. The device as claimed in claim 4 , wherein the handle is configured to move in translation in a direction essentially parallel to the plane of sliding of the movable window.

6. The device as claimed in claim 5 , wherein the handle comprises a rack which meshes with a pinion secured to the rod.

7. The device as claimed in claim 6 , wherein the rack is made to move only once the threshold allowing rotation of the rod is exceeded.

8. The device as claimed in claim 4 , wherein rotation of the ring under action of the handle is limited by one or more stops secured to the frame.

9. The device as claimed in claim 8 , wherein rotation of the rod is limited to position ends of the rod in line with a straight portion of sliding tracks created in the rails.

10. The device as claimed in claim 3 , further comprising return means which are secured to the rod and urge the rod to rotate in an opposite direction from that obtained by actuating the handle.

11. The device as claimed in claim 10 , wherein the return means includes one or more coil springs which surround the rod and are coaxial therewith.

12. The device as claimed in claim 10 , wherein reverse rotational movement, imposed by the return means when the handle is no longer actuated, presses the end of the rod against walls of a sliding track in the rails, braking by friction sliding movement when the window has been removed from a flush closed position of the movable window.

13. The device as claimed in claim 3 , wherein, in addition to the end of the rod sliding in the track, the means engaging with the rails during sliding comprises rollers arranged eccentrically with respect to the end of the rod, the rollers remaining in straight tracks arranged in the rails during movements of the window.

14. The device as claimed in claim 13 , wherein the sliding tracks of the rollers comprise one or more recesses in walls of the track, the recesses receiving the roller under effect of return rotation when the handle ceases to be actuated.

15. A device for opening and closing a movable window, the movable window configured to move with respect to a fixed panel from a closed position, wherein the movable window is arranged flush with respect to the fixed panel, to an open position, wherein the movable window is movable parallel to the fixed panel, the device comprising:
a handle mechanism attached to an edge of a window frame;
an assembly attached to an edge of a frame secured to the movable window, the assembly controlled from a handle mechanism; and
a rod extending along the edge of the frame, the rod having ends for engaging with rails secured to the fixed panel, and the rod having a ring forming a cam,
wherein starting from the closed position, actuation of the handle, in a first stage, unlocks the movable window and, in a second stage after the first stage, further actuation of the handle leads the movable window out of the closed position, an edge of the window corresponding to the edge of the frame, being moved with respect to the fixed panel, toward a position allowing the movable window to slide,
wherein the handle comprises a means engaging with the ring forming the cam thereby preventing rotation of the rod during the first stage of handle actuation until after a threshold in actuation of the handle is reached.

16. The device as claimed in claim 15 , wherein the rod further comprises a pinion, the handle further comprises a rack, and the rack and pinion can only move with respect to each other during the second stage.
