Abstract
A flexible ladder constructed of nylon webbing straps includes a central weight-bearing strap having terminal loops at both ends, and a plurality of opposed pairs of side loops for hand and foot placement.

Claims6
A ladder, comprising:
- a. an elongate primary strap having first and second ends, first and second opposed faces and first and second side edges;
- b. a first elongate ancillary strap, longer than said primary strap, said ancillary strap having first and second ends, first and second opposed faces and first and second side edges;
- c. a second elongate ancillary strap, similar in length to said first ancillary strap, said second ancillary strap having first and second ends, first and second opposed faces and first and second side edges;
- d. a plurality of bound portions of said first ancillary strap's length, said bound portions being parallel to, flush-faced against, edge-aligned with and bound to said primary strap;
- e. a plurality of unbound portions of said ancillary strap's length, each said unbound portion being between two said bound portions;
- f. a twist in an unbound portion of said first ancillary strap;
- g. a plurality of bound portions of said second ancillary strap's length, said bound portions being parallel to, flush-faced against, edge-aligned with and bound to said primary strap;
- h. a plurality of unbound portions of said second ancillary strap's length, each said unbound portion being between two said bound portions;
- and
- i. a twist in an unbound portion of said second ancillary strap.
