Multifunctional collapsible shield

A multifunctional collapsible shield comprising:

• a) an elongated sheet having opposed longitudinal edges;
• b) a pair of elongated panels, each elongated panel having inner and outer longitudinal portions with a longitudinal center therebetween;
• c) means for attaching each longitudinal edge of said elongated sheet to the longitudinal center of each said elongated panel;
• d) a zipper attached to opposite longitudinal edges of the inner portions of said pair of elongated panels, the inner portions being joined together and the elongated sheet being deformed along it's longitudinal length when the zipper is closed so that the elongated sheet in combination with the inner portions form a structural tube with the outer portions of the elongated panels extending away from the formed structural robe to function as guard members, and the inner portions being separated when the zipper is opened to permit the elongated sheet and the longitudinal panels to assume a rolled configuration;
• and
• e) means for securing a forward end of the formed structural tube to a seat post of a seat on a bicycle, said formed structural tube being sufficiently rigid when the zipper is closed to permit a rearward end portion of the formed structural tube to extend unsupported over a rear wheel of the bicycle to act as a fender.
