A multisectional umbrella frame having a stick section with a handle and having an intermediate stick section with a window located at the lower end of said intermediate stick section when the umbrella frame is in its unfolded position of use, in which that stick section which has the handle connected thereto is provided with guiding means, e.g. in the form of a longitudinal groove, arranged below said window while in use position of said stick between the lower edge of said window and the lower edge of the intermediate frame stick there is provided a guiding member for cooperation with said guiding means, said frame also comprising a runner having pivotally connected thereto a pawl the locking section of which has a first edge surface which in said window engaging position engages that window edge surface which faces away from said handle in such a way that the longitudinal plane of symmetry of said pawl is substantially perpendicular to said window edge surface, said pawl having a second edge surface opposite said first edge surface and being so inclined that the extensions of said first and second edge surfaces in the direction away from said stick define an acute angle, said pawl having a third edge surface interconnecting said first and second edge surfaces and forming with said first edge surface an obtuse angle and with said second edge surface an acute angle.
