The invention relates to a foldable umbrella frame having five
ribs (III), wherein the first rib, the second rib, and the fourth
rib are formed to be solid rods with outer flat portion. The third
rib is still U-shaped structure and has its outer end with two
parallel plates for receiving the inner end of the fourth 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

Description
FIELD OF THE INVENTION
[0001] 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
[0002] 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
[0003] 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
[0004] FIG. 1 is a plan view showing a single frame of a convention
five-folded umbrella.
[0005] FIG. 2 is a plan view showing a conventional five-folded
umbrella in closed state.
[0006] FIG. 3 is a plan view showing a single frame having five
ribs according to the present invention.
[0007] 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
[0008] The present invention is to provide an improvement about a
five-folded umbrella. Please refer to FIGS. 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 second rib (32), 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) 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 third branch rib (331), both of which
have inner hook for connecting with outer flat portion of the first
rib (31) and the second rib (32) respectively. The third rib (33)
is still U-shaped structure and has its outer end with two parallel
plates for receiving the inner end of the fourth rib (34) 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.
[0009] 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.
