Claims

[Claims for Utility Model Registration] 1. A structure for pivotally supporting a dowel at the end of a bridge of an umbrella to a main rib, wherein a recess is formed at a predetermined position of the main rib, and the inner surface thereof has a fitting member that extends and fits into the recess, and on the outer surface thereof,
An umbrella characterized in that a plastic dowel integrally molded to have an eyelet protrusion for pivotally connecting with the tip dowel is circumferentially fixed to the main rib by fitting the fitting member into the recess. Pivotal configuration between the strut and the main bone. 2. A pivot structure between an umbrella support rib and a main rib according to claim 1, wherein the recess is formed on a surface of the main rib that corresponds to the protrusion of the plastic dowel. 3. A middle rod, a lower potter's wheel slidably fitted onto the center rod, an upper potter's wheel fixed to the upper end of the center rod, and a plurality of main ribs whose one end is pivoted to the upper potter's wheel. and a plurality of ribs, both ends of which are pivotally supported by the main rib and the lower potter's wheel through tip dowels, respectively, in which a recess is formed at a predetermined position of the main rib, and an inner surface thereof extends into the recess. A plastic dowel is integrally molded so as to have a fitting member to be fitted into the recess, and the outer surface thereof has an eyelet protrusion for pivotally connecting with the tip dowel, and the fitting member is fitted into the recess. An umbrella characterized in that the umbrella is fixed to the main rib. 4. The umbrella according to claim 3, wherein the recess is formed on a surface of the rib that corresponds to the protrusion of the plastic dowel.
