Umbrella with automatic opening mechanism - has release system independent of slider for universal use on all umbrellas

摘要

The umbrella has an opener spring mounted between a main and an auxiliary slider and a tubular release sleeve for the actuating part of the shaft spring. This sleeve which is pref. designed as a cylinder tube with two bulges diametrically opposed relative to the swivel axis is mounted for swivel movement on the stock shaft. The bulge on the side of the handle serves as the pressure face while the other interacts with the actuating part of the shaft spring. The tubular release sleeve spans different sized distances between the pressure face for actuation and the position of the shaft spring or its actuating part can now be used for practically any design of automatic opening umbrellas.
