SEMI-AUTOMATIC UMBRELLA WITH AUTOMATIC RETRACTABLE CENTRAL ROD Russian patent published in 2012 - IPC A45B11/00 

FIELD: textile industry.

SUBSTANCE: semi-automatic umbrella comprises a telescopic central rod, a handle and a slider slidably moving along the rod. The first pulling cord is taut when the rod is pulled out, which causes upward shift of the activating element to affect the spring-loaded retaining slider element for disengagement with the rod after release of the first pulling cord. The element of extension spring connected with a second pulling cord is stretched to create a forced effort. The stretched element of the extension spring provides motion of the slider upwards for putting up the umbrella. After removing the forced effort the motion of the slider downwards causes folding the umbrella and disengagement of the spring-loaded retaining the rod element with the rod, which provides the rod interfolding and folding the umbrella. The technical result of the invention is creation of a semi-automatic umbrella, which can be easily put up and can be folded and taken down automatically.

EFFECT: creation of semi-automatic umbrella which can be easily put up and can be folded and taken down automatically.
