ABSTRACT:
A shortenable umbrella with blades carrying the umbrella canopy, the blades being shortenable by telescoping and/or folding, of which the innermost blade parts are pivoted on a crown secured on a shortenable rod assembly and respectively are horizontally pivotable by means of at least one fork by means of at least one slider, whereby each outermost blade part is hinged foldable onto the adjacent blade part by means of a control rod which acts on an extension of the outermost blade part. The inner-lying end of each control rod surrounds the fork associated therewith by means of a guide opening which is large in area with respect to the cross-section of the fork, the guide opening making possible a displacement of the inner-lying end of the control rod in the longitudinal direction of the fork and/or of the control rod.
