Abstract

A mechanism for moving a door relative to an access opening in a door frame includes three links pivotally connected between the door and the door frame permitting outward and lateral movement of the door. A structural member or pillar releasably secured to the door frame can move with the door and the mechanism can include a supporting member extending beneath and supporting the door during movement.

Claims

1. A door system comprising:

a door frame defining an access opening;

a door assembly including a door covering said access opening and having a top edge, a bottom edge and a pair of opposed side edges extending between said top edge and said bottom edge;

a first link having one end pivotally attached at said door assembly top edge adjacent a first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly top edge;

a second link having one end pivotally attached at said door assembly bottom edge adjacent said first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly bottom edge;

a third link having one end pivotally attached at said door assembly bottom edge and having an opposite end pivotally attached to said door frame whereby said first, second and third links define a path of movement of said door assembly relative to said door frame between a closed position covering said access opening and an open position exposing said access opening, said path of movement being outwardly from said door frame and past a side edge of said access opening; and

a center pillar releasably attached to said door frame at said first one of said door assembly side edges, said first link one end being pivotally secured to a top end of said center pillar and said second link one end being pivotally attached to said door assembly adjacent to a bottom end of said center pillar.

2. The door system according to claim 1 wherein said door assembly includes at least one binge connecting said center pillar to said door whereby said door swings on said hinge between said closed position covering said access opening and another open position partially exposing said access opening.

3. The door system according to claim 1 wherein said door assembly includes a pillar latch releasably securing said center pillar to said door frame.

4. The door system according to claim 1 wherein said door frame is a portion of a vehicle, said door is a rear door on a side of the vehicle and said center pillar separates said access opening from an access opening and associated front door on the side of the vehicle.

5. The door system according to claim 1 wherein said door assembly includes a supporting member extending along said door assembly bottom edge and between said bottom end of said center pillar and said second link one end, said second link one end is pivotally secured to said supporting member and said third link one end is pivotally secured to said supporting member.

6. The door system according to claim 5 wherein said door assembly includes a supporting member latch releasably securing said supporting member to said door.

7. A door system for a vehicle comprising:

a vehicle door frame defining a front access opening and an adjacent rear access opening;

a center pillar attached to said door frame between said front access opening and said rear access opening;

a door assembly covering said rear access opening and having a top edge, a bottom edge and a pair of opposed side edges extending between said top edge and said bottom edge;

a first link having one end pivotally attached at said door assembly top edge adjacent a first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly top edge;

a second link having one end pivotally attached at said door assembly bottom edge adjacent said first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly bottom edge;

a third link having one end pivotally attached at said door assembly bottom edge and having an opposite end pivotally attached to said door frame whereby said first, second and third links define a path of movement of said door assembly relative to said door frame between a closed position covering said rear access opening and an open position exposing said rear access opening, said path of movement being outwardly from said door frame and past a side edge of said rear access opening; and

a door attached to said center pillar, said center pillar being releasably attached to said door frame, said first link one end being pivotally secured to a top end of said center pillar and said second link one end being pivotally attached to said door assembly adjacent to a bottom end of said center pillar.

8. The door system according to claim 7 wherein said door assembly includes at least one binge connecting said center pillar to said door whereby said door swings on said hinge between said closed position covering said rear access opening and another open position partially exposing said rear access opening.

9. The door system according to claim 7 wherein said door assembly includes a pillar latch releasably securing said center pillar to said door frame.

10. The door system according to claim 7 wherein said door assembly includes a supporting member extending along said door assembly bottom edge and between said bottom end of said center pillar and said second link one end, said second link one end is pivotally secured to said supporting member and said third link one end is pivotally secured to said supporting member.

11. The door system according to claim 10 wherein said door assembly includes a supporting member latch releasably securing said supporting member to said door.

12. A door moving mechanism comprising:

a door frame defining an access opening and having a releasably attached structural member defining an edge of said access opening;

a door pivotally attached to said structural member for a first mode of operation swinging between a closed position coveting said access opening and an open position exposing said access opening; and

a mechanism supporting said structural member and said door and being pivotally secured to said door frame, said mechanism being selectively operable in a second mode of operation for pivoting outwardly from said access opening and moving said structural member and said door laterally relative to said access opening.

13. The door moving mechanism according to claim 12 including a pillar latch releasably securing said structural member to said door frame.

14. The door moving mechanism according to claim 13 including a sensor connected to said pillar latch and a control connected to said pillar latch and said sensor for selectively latching and unlatching said structural member.

15. The door moving mechanism according to claim 12 wherein said mechanism includes a supporting member extending along a bottom edge of said door for supporting said door during said second mode of operation.

16. The door moving mechanism according to claim 15 including a supporting member latch releasably securing said supporting member to said door.

17. The door moving mechanism according to claim 16 including a sensor connected to said supporting member latch and a control connected to said supporting member latch and said sensor for selectively latching and unlatching said supporting member.

18. The door moving mechanism according to claim 12 wherein said mechanism includes a first link having one end pivotally attached at a top edge of said door adjacent a first side edge of said door and having an opposite end pivotally attached to said door frame adjacent said door top edge, a second link having one end pivotally attached at a bottom edge of said door adjacent said first side edge and having an opposite end pivotally attached to said door frame adjacent said door bottom edge;

and a third link having one end pivotally attached at said door bottom edge and having an opposite end pivotally attached to said door frame whereby said first, second and third links define a path of movement of said door relative to said door frame between a closed position covering said access opening and an open position exposing said access opening, said path of movement being outwardly from said door frame and laterally past a side edge of said access opening.
