Abstract

A system for managing opening and closing a pocket door includes a spindle, an actuator, and brackets. The spindle extends along a longitudinal axis between first and second ends, and is configured to be coupled to the pocket door. The actuator is coupled to the spindle and is configured to cause the spindle to move axially along the longitudinal axis. The brackets are connected to the spindle at each end and are constrained from longitudinal motion relative to the spindle. The brackets are configured to affix the spindle to the pocket door. A bushing system couples each bracket to the spindle and is configured to dampen impact between the spindle and the brackets. For example, the bushing system may include lobed elements, made of a rubber material, that engage each other to transmit azimuthal forces. In some embodiments, another actuator is included to improve cycle like and redundancy.

First claim

What is claimed is:

1. A system for managing opening and closing a pocket door of a vehicle, the system comprising:
a rail system having a longitudinal axis, wherein the rail system is arranged along a top of a doorway;
a pocket door engaged with the rail system and extending below the rail, wherein the pocket door is configured to translate along the longitudinal axis, and wherein the pocket door is supported by the rail system; and
an actuator system comprising:
a spindle extending along the longitudinal axis and coupled to the pocket door, wherein the spindle is arranged above the pocket door; and
an actuator coupled to the spindle and configured to cause the spindle to move axially along the longitudinal axis.

2. The system of claim 1 , wherein the pocket door comprises a top side, a first longitudinal side, and a second longitudinal side, and wherein the spindle comprises a first end and a second end, the system further comprising:
a first bracket connected to the pocket door on the first longitudinal side at the top side, wherein the first bracket is connected to the spindle at the first end such that the first bracket is constrained from longitudinal motion relative to the spindle;
a second bracket connected to the pocket door on the second longitudinal side at the top side, wherein the second bracket is connected to the spindle at the second end such that the second bracket is constrained from longitudinal motion relative to the spindle.

3. The system of claim 2 , further comprising:
a first bushing system that couples the first bracket to the first end of the spindle, wherein the first bushing system is configured dampen impact between the spindle and the pocket door; and
a second bushing system that couples the second bracket to the second end of the spindle, wherein the second bushing system is configured dampen impact between the spindle and the pocket door.

4. The system of claim 3 , wherein the first bushing system comprises:
a first member connected to the first end of the spindle;
a second member connected to the first bracket such that the second member is constrained from rotating about the longitudinal axis relative to the first bracket; and
a third member affixed to the second member and engaged with the first member to dampen impact between the first member and the third member.

5. The system of claim 4 , wherein the first member comprises a first extension that extends along the longitudinal axis through the third member, the second member, and the first bracket, the system further comprising a fastener engaged with the first extension to apply an axial preload along the longitudinal axis to the first bracket, the second member, and the first member.

6. The system of claim 4 , wherein:
the first member comprises a plurality of lobes arranged azimuthally around the longitudinal axis;
the third member comprises a plurality of lobe recesses arranged azimuthally around the longitudinal axis; and
the plurality of lobes engage with the plurality of lobe recesses to transfer an azimuthal load.

7. The system of claim 1 , wherein the spindle is threaded, and wherein the actuator engages with threads of the spindle.

8. The system of claim 1 , wherein the rail comprises a cutout through which the spindle is removable while coupled to the actuator.

9. The system of claim 1 , wherein the actuator is a first actuator, the system further comprising a second actuator coupled to the spindle and configured to cause the spindle to move axially along the longitudinal axis, wherein the first actuator and the second actuator are spaced along the longitudinal axis by a predetermined distance.

10. The system of claim 1 , wherein the actuator is arranged vertically and substantially above the spindle.

11. The system of claim 1 , wherein the actuator is arranged horizontally and substantially on a side of the spindle.

12. The system of claim 11 , further comprising a bracket, wherein the bracket attaches the actuator and the rail, and wherein the bracket is arranged on top of the rail.

13. A system for managing opening and closing a pocket door, the system comprising:
a spindle extending along a longitudinal axis and configured to be coupled to the pocket door, wherein the spindle comprises a first end and a second end;
an actuator coupled to the spindle and configured to cause the spindle to move axially along the longitudinal axis;
a first bracket connected to the spindle at the first end such that the first bracket is constrained from longitudinal motion relative to the spindle, wherein the first bracket is configured to be connected to the pocket door; and
a second bracket connected to the spindle at the second end such that the second bracket is constrained from longitudinal motion relative to the spindle, wherein the second bracket is configured to be connected to the pocket door.

14. The system of claim 13 , further comprising:
a first bushing system that couples the first bracket to the first end of the spindle, wherein the first bushing system is configured dampen impact between the spindle and the first bracket; and
a second bushing system that couples the second bracket to the second end of the spindle, wherein the second bushing system is configured dampen impact between the spindle and the second bracket.

15. The system of claim 14 , wherein the first bushing system comprises:
a first member connected to the first end of the spindle;
a second member connected to the first bracket such that the second member is constrained from rotating about the longitudinal axis relative to the first bracket; and
a third member affixed to the second member and engaged with the first member to dampen impact between the first member and the third member.

16. The system of claim 15 , wherein the third member is comprised of a rubber material.

17. The system of claim 15 , wherein the first member comprises a first extension that extends along the longitudinal axis through the third member, the second member, and the first bracket, the system further comprising a fastener engaged with the first extension to apply an axial preload along the longitudinal axis to the first bracket, the second member, and the first member.

18. The system of claim 15 , wherein:
the first member comprises a plurality of lobes arranged azimuthally around the longitudinal axis;
the third member comprises a plurality of lobe recesses arranged azimuthally around the longitudinal axis; and
the plurality of lobes engage with the plurality of lobe recesses to transfer an azimuthal load.

19. The system of claim 13 , wherein the spindle is threaded, and wherein the actuator engages with threads of the spindle.

20. The system of claim 13 , further comprising a bracket, wherein the bracket is configured to attach the actuator to a rail.
