ABSTRACT OF THE DISCLOSURE A shortenable umbrella with blades carrying the umbrella canopy in opened condition, the blades being shortenable at least by a factor of two by telescoping or folding, of which the innermost blade part is pivoted on a crown secured on the shortenable rod and are pivotable by means of at least one fork by means of at least one slider, whereby the outermost blade part is hinged foldable on the adjacent blade part by means of a control rod which acts on an extension of the outermost blade part. The umbrella is characterized in that the inner end of the control rod engaging directly and positively without friction or slipping on the outermost blade part is pivotably fastened to a slide hinge, which slide hinge is displaceably disposed on the middle blade part in the vicinity of the middle hinge and is articulated play-free on the fork by means of a short connecting rod. The latter is as little as possible longer than the distance between its pivot point on the fork and the pivot point of the fork on the associated corresponding blade part. - 1 -
