Abstract

A sliding door is closed by a reversible power-driven slide, movable horizontally and having a hook normally coupled to a detent on the door for causing the door to move with the slide in a closing direction. A coupling hook pivoted on the slide, and spring loaded toward operative position, is retracted or uncoupled from the detent at the conclusion of the door closing movement by the engagement of a retracting lever arm on the hook with a fixed stop, thus releasing the door from the slide so that it may be subsequently manually opened. For opening of the door by remote control, a return or reverse movement of the slide, and its abutting engagement with the detent, transmits opening movement to the door while, at the same time, reengaging the hook for use in subsequently closing the door by remote control.

Claims

1. Remote control mechanism for a door guided for horizontal movement into and from closing relation to a door opening in the body of a vehicle, wherein the improvement comprises a driven slide;

means supported from the vehicle body for guiding said slide for operative horizontal movement back and forth across said opening;

a detent carried by said door in fixed relation thereto;

a hook pivotally carried by said slide for operative engagement with said detent to couple said door to said slide for movement therewith;

a retracting arm carried by said hook; and

a stop carried by said vehicle body in the path of movement of said retracting arm for engagement by said arm to disengage said hook from said detent when said door has been moved to preselected location.

2. Remote control mechanism as defined in claim 1, in which said detent comprises a bolt fixedly supported from the sliding door.

3. Remote control mechanism as defined in claim 1, in which said stop includes a guide means for said retracting arm.

4. Remote control mechanism as defined in claim 2, in which said hook is mounted for swinging movement in a horizontal plane about a perpendicular axis for operative engagement and disengagement with said bolt, said bolt extending perpendicularly across the path of said swinging movement, and which includes spring means for urging said hook in a direction for operative engagement with said bolt, said stop and said retracting aRm cooperating to swing said hook in a direction to retract it from engagement with said bolt against the spring action.

5. Remote control mechanism as defined in claim 4, in which said hook includes means defining a cam surface for operative engagement with said bolt, upon movement of said hook in a direction opposite to that in which it moves when it couples said door to said slide, to retract said hook, thereby allowing said hook to move past said bolt in said opposite direction, whereby subsequent operative engagement of said hook with said bolt to couple said door to said slide may take place under the action of said spring means.

6. Remote control mechanism as defined in claim 1, including driving means for said slide, said driving means including a threaded shaft mounted for rotation in threaded engagement with said slide.

7. Remote control mechanism as defined in claim 1, including driving means for said slide, said driving means including a cable mounted for shifting movement in engagement with said slide.

8. Remote control mechanism as defined in claim 6, in which said threaded shaft is disposed within said slide guiding means.

9. Remote control mechanism as defined in claim 6, wherein said driving means includes a driving motor operatively connected with said threaded shaft for rotating the latter.

10. Remote control mechanism as defined in claim 1, further comprising a second detent carried by said door in fixed relation thereto, a second slide and associated hook, retracting arm and stop, all as defined in claim 1, but with said second slide and associated hook, retracting arm, and stop being arranged to engage and disengage said second detent in opposite directions of movement, respectively, from those of said first hook.

11. Remote control mechanism as defined in claim 1, in which said hook is positioned to establish an operative coupling with said door during movement of said slide in the direction to open said door.

12. Remote control mechanism as defined in claim 1 in which said hook is positioned to establish an operative coupling with said door during movement of said slide in a direction to close said door.
