Abstract

The invention relates to a foldable umbrella frame having five ribs (II), wherein the first rib, the third rib, and the fourth rib are formed to be solid rods with outer flat portion. The second rib is still U-shaped structure and has its outer end with two parallel plates for receiving the inner end of the third rib when closing the umbrella. The ribs are pivoted to form a frame. Branch ribs have inner hooks to connect with outer flat portion that provides a small volume of the umbrella in closed state for facilitating carrying by users.

Description

    FIELD OF THE INVENTION
  • The present invention relates to a foldable umbrella frame having five ribs, which is particularly about an improvement of a five-folded umbrella.
    • BACKGROUND OF THE INVENTION
  • Generally, a five-folded umbrella is an umbrella having five ribs to assemble the frame that obtains a small volume for facilitating carrying by users. As shown in FIG. 1,, each of the conventional umbrella frames (1) includes a first rib (11), a second rib (12), a third rib (13), a fourth rib (14), and a tail rib (15). It is known that the-first rib (11), the second rib (12), and the third (13) are usually formed to have a U-shape cross-section and the ribs are pivoted with each other. When the conventional umbrella is closed as shown in FIG. 2, the ribs will be resistant against others and make the frame (1) be slightly expanded. Accordingly, the five-folded umbrella has a short length but has a large diameter. The volume of the collapsible umbrella in closed state is still large and it is not very convenient for carrying.
    • SUMMARY OF THE INVENTION
  • The present invention is to provide a five-folded umbrella having five ribs, wherein the ribs are improved to overcome the drawback of the conventional one. Hence, the improved umbrella can provide a small volume for facilitating carrying. Now, accompanying with the following drawings, the character of the present invention will be described here and after.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a plan view showing a single frame of a convention five-folded umbrella.
  • FIG. 2 is a plan view showing a conventional five-folded umbrella in closed state.
  • FIG. 3 is a plan view showing a single frame having five ribs according to the present invention.
  • FIG. 4 is a plan view showing a five-folded umbrella in closed state according to the present invention.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The present invention is to provide an improvement about a five-folded umbrella. Please refer to FIG. 3 and 4, it shows a foldable five-folded umbrella, which includes a first rib (31), a second rib (32), a third rib (33), a fourth rib (34), and a tail rib (35) to assemble a frame (3). The characteristic of the present invention is the first rib (31), the third rib (33), and the fourth rib (34) are formed to be solid ribs, wherein the first rib (31) has its both ends and middle portion to be flat structure while the third rib (33) and the fourth rib (34) have their outer end to be flat. The umbrella of this invention also includes a second branch rib (321) and a fourth branch rib (341), both of which have inner hook for connecting with outer flat portion of the first rib (31) and the third rib (33) respectively. The second rib (32) is still U-shaped structure and has its outer end with two parallel plates for receiving the inner end of the third rib (33) when closing the umbrella. Hence, the umbrella according to the present invention has a small volume as it is closed since the flat portions avoid resistance between the ribs.
  • Above all, the present invention mainly improves the structure of umbrella ribs and their connecting structures. It provides a small volume of the five-folded umbrella in closed state that obtains the improvement and utilization.
