Full-automatic multi-fold umbrella

Abstract

A full-automatic multi-fold umbrella comprises an umbrella framework, an umbrella fabric, a middle rod set, an upper runner, a lower runner, an umbrella handle and an opening-closing control mechanism disposed inside the middle bar set. The middle bar set includes an outer tube, a middle tube and an inner tube. A fixed pulley is disposed at the upper end of the outer tube. A moving pulley is disposed at the top of the middle tube. The opening-closing control mechanism comprises a pusher and a speed changer. The pusher comprises a screw, a nut fitted to the screw, and a push rod. The push rod is connected with the nut and a middle tube plug. The lower end of the screw is driven by a power source inside the umbrella handle. The speed changer comprises a lower runner pull cord and a middle tube pull cord. One end of the lower runner pull cord is connected to the middle tube plug, and the other end of the lower runner pull cord passes by the fixed pulley and passes through the outer tube to be fixed together with the lower runner. One end of the middle tube pull cord is connected to an inner tube plug, and the other end of the middle tube pull cord passes by the moving pulley to be fixed to the lower end of the outer tube. The power source is controlled through a button on the umbrella handle. The power source drives the screw to rotate to drive the nut in vertical motion, and enables the tubes of the middle bar set and the umbrella fabric to be in linkage of opening and closing.

Description

technical field [0001] The invention relates to an umbrella, in particular to a fully automatic multi-folding umbrella that can be fully opened and fully folded. Background technique [0002] In recent years, due to the erratic climate, everyone has the habit of carrying an umbrella to prevent the sudden heavy rain from being drenched. But the early stage umbrellas need to push the umbrella frame up to a certain position by hand to open the umbrella. In case of a sudden rain, it is often too late to open the umbrella and get wet.

In the car, it is still vulnerable to rain in this short period of time, so it loses the convenience of the umbrella itself. [0003] The typical structure...
