Claims20
A structural extending member comprising:
- a support structure having a cavity adapted to support a coiled flexible metal tape, wherein the support structure comprises a first end plate, at least one interior plate, and a second end plate,
- a spool piece contained within the cavity of the support structure,
- a flexible metal tape having a length in an extended form, a first end and a second end wherein the first end of the flexible metal tape is attached to the spool piece,
- rotary mechanical means adapted to wind the flexible metal tape onto the spool piece and unwind the tape to the extended form,
- wherein a cross section of the flexible metal tape in the extended form has both convex portions and concave portions facing in the same direction, and
- wherein the cross section of the flexible metal tape has a first edge and a second edge.
