Claims

[Scope of Claim for Utility Model Registration] 1. In a multi-stage telescoping umbrella shaft formed by inserting a plurality of tubes 4, 5, and 6 in a nested manner, when the umbrella is opened, the lower potter's wheel 8 is placed on the tip side of the plurality of tubes. A repellent member 13 is attached to one end of the pipe body so as to lock onto the pipe body 4 of the pipe body, and a repelling member 13 that can move forward and backward into a slit 42 formed in the wall of the pipe body is attached to one end. A lower potter's wheel locking device 1 consisting of a U-shaped spring piece 11 to which a small protrusion 12 is attached that is fitted into a small hole 41 formed in the tube wall of the tube body, a nested tube body 5 that adjoins each other when the umbrella is opened, 6
The inner pipe body 5 to be locked so that they are locked together
Windows provided in the tube wall of the outer tube body 6 at both ends to fit into window holes 54 and 55 made in the tube wall of the inner tube body and to correspond to the window holes when the umbrella is opened. Protrusions 22, 2 that can move forward and backward into holes 61, 62
The above-mentioned multi-stage telescopic umbrella shaft is characterized in that it is provided with: a tube locking device 2 consisting of a U-shaped spring piece 21 to which a U-shaped spring piece 21 is attached; 2. The multi-stage telescoping umbrella shaft according to claim 1, wherein the U-shaped spring pieces 11 of the lower potter's wheel locking device 1 have different end positions. 3. The multi-stage telescopic umbrella shaft according to claim 1, wherein the U-shaped spring pieces 21 of the tubular body locking device 2 have different end positions.
