Abstract
An umbrella includes a substantially inextensible cord which is mounted by couplers to the free ends of the ribs of the umbrella such that the cord forms a closed loop disposed radially inwardly of the ribs of the umbrella. The cord braces the umbrella against inversion, and the couplers can be designed to allow the cord to be retrofitted to an existing umbrella.
