Abstract

The invention provides a practical reversed closed umbrella that can enhance strength of the main frame when opening the umbrella, and can perform open and close of the umbrella smoothly. The reversed closed umbrella (1) comprises a three layer axle construction of a main rod (5), a sliding rod (11) and a cylindrical rod (14); top end of the sliding rod (11) is provided with a main frame supporting part (113) that supports one end of a plurality of main frames (12); root of the cylindrical rod (14) is provided with a branch frame supporting part (141) that supports one end of a plurality of first branch frames (15); the other end of the first branch frame (15) pivoted to the main frame (12), and can support one end of the second branch frame (16) in a sliding way. One end of the second branch frame (16) is jogged in a branch frame embedding groove (151) of the first branch frame (15) in a sliding way, and the other end is pivoted to the main frame (12).

Description

technical field [0001] The present invention relates to a reverse closure umbrella capable of accommodating a surface wetted by rain inside. Background technique [0002] An umbrella described in Patent Document 1 is known as a reverse closing umbrella. According to this patent document 1, it is known that the reverse closing umbrella has a main rod, a sliding rod, and a cylindrical rod to form a three-layer shaft structure. That is, the handle is attached to the main pole disposed inside, and one end of the main frame to which the tarpaulin is attached is pivotally supported on the slide bar slidably fitted over the main pole. The second slider part is disposed on the cylindrical rod slidably overlaid on the sliding rod, and the second slider part pivotally supports one end of the support frame at the base side, and the other end of the support frame is pivotally supported on the main frame. . And, in the closed state of the umbrella, when the sliding rod is slid relativ...
