Portable curtain retraction device and system
View Patent ↗A portable barrier retraction device and system for retracting and deploying barriers, such as theatrical curtains. The portable barrier retraction device for retracting and deploying barriers, such as theatrical curtains. The device includes a rotatable shaft in rotational communication with a first drum. The device further includes a detachable rotatable second drum rotational communication with the first drum. The second drum further including at least one spool configured to retract or deploy at least one line in response to rotation of the second drum.
1. A portable barrier retraction device comprising:
a first drum;
a rotatable shaft in selective rotational communication with the first drum;
a clutch configured to disengage the first drum from the rotatable shaft;
a detachable rotatable second drum in rotational communication with the first drum, the second drum comprising a first spool configured to independently retract or deploy a line in response to rotation of the second drum and a second spool configured to independently retract or deploy a second line in response to rotation of the second drum;
wherein the shaft selectively imparts rotation to the second drum by selectively imparting rotation to the first drum.
2. The device of claim 1 , wherein the lines are retractable in a manner that forms a festoon pattern in the barrier during retraction.
3. The device of claim 2 , wherein the barrier is a theatrical cuff am.
4. The device of claim 1 , wherein the barrier retraction device provides asymmetrical deployment of the barrier.
5. The device of claim 1 , wherein the rate of retraction or deployment may be increased or decreased.
6. The device of claim 1 , wherein the second drum is attached to the barrier.
7. The device of claim 1 , wherein the second drum further includes a locking device, wherein the locking device selectively prevents rotation of the second drum and the spool.
8. The device of claim 1 , wherein the first drum and the second drum comprise a geared arrangement.
9. A portable barrier retraction system comprising:
a barrier having at least one line disposed adjacent thereto,
at least one barrier retraction device having:
a first drum;
a rotatable shaft in selective rotational communication with the first drum;
a clutch configured to disengage the first drum from the rotatable shaft;
a detachable rotatable second drum in rotational communication with the first drum, the second drum comprising a first spool that independently retracts or deploys a line in response to rotation of the second drum and a second spool configured to independently retract or deploy a second line in response to rotation of the second drum;
wherein the shaft selectively imparts rotation to the second drum by selectively imparting rotation to the first drum; and
a support frame into which the first drum and second drum are independently mounted.
10. The system of claim 9 , wherein the lines attach to the barrier in a location along the surface of the barrier that permits retraction of the barrier.
11. The system of claim 9 , wherein the lines are retractable in a manner that forms a festoon pattern in the barrier during retraction.
12. The system of claim 11 , wherein the barrier is a theatrical curtain.
13. The system of claim 9 , wherein the barrier retraction device provides asymmetrical deployment of the barrier.
14. The system of claim 9 , wherein the rate of retraction or deployment may be increased or decreased.
15. The system of claim 9 , wherein the first drum and the second drum comprise a geared arrangement.
16. The system of claim 9 , wherein the second drum is attached to the barrier.
17. The system of claim 9 , wherein the shaft is arranged in a circular geometry.
18. The system of claim 9 , wherein the shaft comprises a plurality of segments rotatably coupled together.
19. The system of claim 9 , further comprising a driver configured to rotate the shaft.
20. The system of claim 9 , wherein the barrier, the at least one barrier retraction device and the frame disassemble into components that are capable of being stored in the cargo hold of an aircraft.
