Abstract
This invention relates to the use of suspended materials as a backdrop for photography or stage productions. The suspended materials may be stored on a spool device. Such spool devices may include tubes or spindles constructed of metal, of cardboard, of plastic or other lightweight and inexpensive materials. The spool device may also include means for attaching the tube or spindle to a lifting device. Such attachment means may include a pair of interconnectable coupling devices, one fixed to the spool and the second attached to the lifting device.
Claims25
A backdrop system comprising:
- a backdrop spool for receiving thereon a backdrop, the spool having a tube with a flange adjacent to a first end and a flange adjacent to a second end;
- a lifting device for adjusting the vertical position of the spool;
- a rolling device for rolling and unrolling the backdrop on the backdrop spool;
- and
- a lifting mount for attaching the spool to the lifting device, the backdrop spool being removable from the lifting mount at a lowered vertical position by unlocking a lock configured to secure flanges to the lifting mount.
A method of changing a spool of a backdrop system, the spool having a tube with a flange adjacent to a first end and a flange adjacent to a second end;
- one or more mating members disposed within the flanges;
- a lifting device for adjusting the vertical position of the spool;
- a rolling device for rolling and unrolling the backdrop on the backdrop spool;
- and a lifting mount for attaching the spool to the lifting device;
- one or more mating members disposed within the lifting mount and configured to receive or be received by the mating members of the flanges, the backdrop spool being removable from or attachable to the lifting mount at a lowered vertical position, the method comprising:
- lowering a first spool from a first height to a second height;
- removing the first spool from a suspension system by disconnecting mating members of the flange from mating members of the lifting mount;
- obtaining a second spool having a tube with a flange adjacent to a first end and a flange adjacent to a second end and having one or more mating disposed within the flanges;
- attaching the second spool to the suspension system by connecting mating members of the flanges to mating members of the lifting mount;
- and
- raising the second spool to the first height.
A backdrop system comprising:
- a backdrop spool for receiving thereon a backdrop, the spool having a tube with a flange adjacent to a first end and a flange adjacent to a second end;
- one or more mating members disposed within the flanges;
- a lifting device for adjusting the vertical position of the spool;
- a rolling device for rolling and unrolling the backdrop on the backdrop spool;
- and
- a lifting mount for attaching the spool to the lifting device;
- one or more mating members disposed within the lifting mount and configured to receive or be received by the mating members of the flanges, the backdrop spool being removable from or attachable to the lifting mount at a lowered vertical position.
