ABSTRACT:
The invention relates to a collapsible umbrella having at least one pair of anopy rod parts (1,2), which extend alongside one another and are guided so as to be displaceable on one another, within each linkage of the canopy-supporting linkage frame. One of the canopy rod parts (2) is composed of wire, and guided on the other rod part (1) by means of a bight (2e) of the wire which embraces the other rod part and is formed with hooks (2f,2g) which can be spread to allow the bight to be fitted transversely on the other rod.
