Windproof Umbrella Frame

Abstract

A windproof umbrella frame is presented comprising a main rib ( 1 ) supporting a canopy, a support rib ( 2 ), and a connecting rod ( 3 ) connecting the main rib ( 1 ) and the support rib ( 2 ). A center plate ( 5 ) is arranged at the middle-section of the main rib ( 1 ). A support rib joint ( 6 ) is fixedly arranged at one end of the support rib ( 2 ). One end of the connecting rod ( 3 ) is hinged to the center plate ( 5 ) along the main rib ( 1 ) and the other end is integrally formed with the support rib joint ( 6 ). The support rib joint ( 6 ) and the connecting rod ( 3 ) are connected by a flexible soft plastic segment ( 31 ). The soft plastic segment ( 31 ) has a tab ( 34 ) arranged along the outside thereof so as to extend radially outward therefrom. The windproof umbrella frame of the present invention is easy and convenient to assemble, robust, and less costly.

1 . A windproof umbrella frame comprising:
 a main rib supporting an umbrella fabric;   a support rib; and   a connecting rod disposed between said support rib and said main rib, said main rib includes a center plate centrally disposed thereon, said support rib includes a support rib joint at an end thereof;   wherein, one end of said connecting rod hingedly connected to said center plate and another end of said connecting rod integrally molded to said support rib joint, said support rib joint connected to said connecting rod via a soft plastic segment, said soft plastic segment being flexible and includes a tab that extends radially outward therefrom.
