ABSTRACT:
A shortenable umbrella with frame or blade parts carrying the umbrella canopy in opened condition, the frame parts being shortenable at least by a factor of two by telescoping or folding, of which the innermost parts are pivoted on a crown secured on a shortenable rod assembly and are horizontally pivotable by means of at least one slider by means of at least one set of forks, whereby each outermost blade part is hinged foldable on the adjacent blade part by means of a control rod which acts on an extension of each outermost blade part. A control piece is formed as a slide hinge which is displaceably guided on the fork, the slide hinge being articulated on the middle hinge by means of a connection portion spaced from the articulation point of the fork. The inner end of the control rod is articulated pivotally on the control piece, the movement of the fork actuating the control piece.
