So that the inner otockteiΊ not unh <-: sbs: iohti £; t --- y, .u that from serf It is known to arrange vines (ien doerri / .u ^ an inner stick fine i'ilete, the head of which lies against the guide bead of the iiusaero.n stick part. Om the two stick parts for the purpose of contemplation) ';.; ichon to be able to, it is reiter confessed to arrange an en oineiH Seclercirrtt attached stop pin in the inner otocktfi.il next to the locking cranks, which, when the stick parts are extended, lies against an embossing of the scr en Stoe: ^ - part and to arrange a hole in the outer part through which the stop pin can be pressed inwards so that the lock is released.

These known umbrella sticks have the disadvantage that they are relatively complex and precise to manufacture processing operations to be carried out are necessary.

The task of the furnace is to create a collapsible umbrella stick that can be produced with the least possible and easy processing operations and with only a few parts a reliable locking in the extended state as well as a reliable, but easy to remove for assembly purposes, locking and unintentional pulling apart of the stick parts.

This task gets done in an amazingly simple way according to the new solution that in the Mihrungs ™ bead a hole in the inner part of the stick to allow passage the one under the action of a spring Locking ball. Is arranged and at the inner end of the a few centimeters long guide bead on the outside Stuck a hole is arranged, the diameter of which is slightly smaller than the diameter of the Locking ball and its at the end of the outer stick part convenient hand that G-round cuts the bead.

When the two stick parts are pulled apart, the locking ball strikes the hand of the hole formed by the walls of the guide bead of the outer stick part and engages in the hole. Since the edge of the hole located towards the center of the outer stick part is further outwards than the edge located towards the cortex of the outer stick part, the two stick parts can be left out of the locked position after applying a force of, for example. Push together 5 to 10 kg, but the upper parts cannot work even when great forces are applied; the locked position further apart ge so against v. ^r e.rden. However, if you want to pull the otock parts apart for assembly, the blocking ball only needs to be pressed inwards, e.g. with a hail or the like.

The umbrella stick shown in FIG. 1 consists of the outer stick part 1 and the inner stick part 2. In a known manner, the outer stick part is in area 3 for guiding the two stick parts 1 and 2 its end 4 narrows somewhat and has in this narrowed area 3 a lengthwise, a few centimeters long guide bead 5 reaching up to the end of the stick part 4, which is inserted into a correspondingly longitudinal guide bead 6 of the inner stick part 2 protrudes.

As particularly FIGS. 3 and 4 show, a bore is arranged in the guide bead 6 of the inner stick part 2, the diameter of which corresponds approximately to the diameter of a locking ball o and the width of the guide bead. The änerrkugcl ■ '.- ·. Is arranged by a spring arranged in the interior of the inner part 2, in particular a leaf spring which is bent in a V-shape ^: j outwardly d ^;

On the other volume of the guide SBieke 5 of the outer, floor part 1 is a B-earring ^: 10-arranged, the diameter of which
