Claims20
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.
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.
