Abstract

The foldable umbrella frame has six ribs. The first rib 31, the second rib 32, the third rib 33, and the fourth rib 34 are formed to be solid rods with outer flat portion. The ribs are pivoted to form a frame. Branch ribs 321, 331, 341 and 351 have inner hooks to connect with the outer flat portion of a respective rib that provides a small volume of the umbrella in closed state for facilitating carrying by users.

Description

TITLE: Foldable Umbrella Frame Having Six Ribs
FIELD OF THE INVENTION
The present invention relates to a foldable umbrella frame having six ribs, which is particularly about an improvement of a six-folded umbrella.
BACKGROUND OF THE INVENTION
Generally, a six-folded umbrella is an umbrella having six ribs to assemble the frame that obtains a small volume for facilitating carrying by users. As shown in Figure 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), a fifth rib (15), and a tail rib (16). It is known that the first rib (11), the second rib (12), the third rib (13), and the fourth rib (14) are usually formed to have a U-shaped cross-section and the ribs are pivoted with each other. When the conventional umbrella is closed as shown in Figure 2, the ribs will be resistant against others and make the frame (1) be slightly expanded. Accordingly, the six-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 six-folded umbrella having six 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
Figure 1 is a plan view showing a single frame of a convention six-folded umbrella.
Figure 2 is a plan view showing a conventional six-folded umbrella in closed state.
Figure 3 is a plan view showing a single frame having six ribs according to the present invention.
Figure 4 is a plan view showing a six-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 six-folded umbrella. Please refer to Figure 3 and 4, it shows a foldable six-folded umbrella, which includes a first rib (31), a second rib (32), a third rib (33), a fourth rib (34), a fifth rib (35), and a tail rib (36) to assemble a frame (3). The characteristic of the present invention is the first rib (31), the second rib (32), 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 second rib (32), 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), a third branch rib (331), a fourth branch rib (341), and a fifth branch rib (351), all of which have inner hook for connecting with outer flat portion of the first rib (31), the second rib (32), the third rib (33), and the fourth rib (34) respectively. 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 six-folded umbrella in closed state that obtains the improvement and utilization. j
