Umbrella ribs of a foldable umbrella
Abstract
The invention relates to an umbrella rib assembly of a foldable
umbrella, particularly a five-folded umbrella, which includes a
first rib to fifth rib and several branch ribs and elastic ribs. It
is characterized in that the third rib has formed a bending portion
at inner end near to the second rib. While the umbrella is closed
and folded, the fourth rib can be fallen beside pivoted end of the
second rib and the third rib that decreases the closed volume of
the umbrella. So the closed umbrella is very conveniently for
carrying or storing.

Claims
I claim:
1. An umbrella rib assembly of a foldable umbrella, particularly a
five-folded umbrella including a first rib to fifth nib and several
branch ribs and elastic ribs, which is characterized in that the
third rib has formed a bending portion at inner end, and while the
umbrella is closed and folded, the fourth rib being fallen beside
pivoted end of the second rib and the third rib that decreases the
closed volume of the umbrella.
2. An umbrella rib assembly of a foldable umbrella as claimed in
claim 1, wherein the fourth rib is formed a bending portion at
inner end, in which the bending direction is reversed to the
bending portion of the third rib.
Description
BACKGROUND OF THE INVENTION
[0001] A foldable umbrella has been designed popularly, which is
small when it is closed that will be very convenient for people to
carry or store. It is known that a five-folded umbrella is the
smallest one in newer day. The frame of the five-folded umbrella is
shown in FIG. 1, which includes the first rib (1) to the fifth rib
(5) connecting with a shaft (6) as well as branch ribs and elastic
ribs. When the said umbrella is closed, the third rib (3) and the
fourth rib (4) will contact with each other. Since both ribs are
rigid round rod, the frame cannot be decreased the closed volume
efficiently. Hence, the umbrella is still somehow large when it is
closed.
[0002] Accordingly, the present invention is to provide an
improvement of umbrella ribs of a foldable umbrella, especially to
a five-folded umbrella, which can be decreased the closed volume
effectively as it is closed and folded.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] FIG. 1 is a plan view showing a prior closed five-folded
umbrella.
[0004] FIG. 2 is a plan view showing a closed five-folded umbrella
according to the present invention.
[0005] FIG. 3 is a perspective view showing a rib assembly of the
frame of the present invention.
[0006] FIG. 4 is a plan view of FIG. 3.
[0007] FIG. 5 is a top plan view of FIG. 4.
[0008] FIG. 6 to 8 are top plan views showing other embodiments
according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0009] Please referring to FIG. 2 to 5, the present invention
relates to a five-folded umbrella, which includes a shaft (6)
connecting with a frame being composed by several rib assembly.
Each rib assembly includes a first rib (1), a second rib (2), a
third rib (3), a fourth rib (4), a fifth rib (5), and several
branch ribs and elastic ribs that are similar to a prior known
five-folded umbrella. It is the characteristic that the third rib
(3) of the present invention is formed a bending portion (31) near
to outer end of the second rib (2). So the rib assembly will not be
fallen in a straight line. It can be found that when the umbrella
is closed and folded, the fourth rib (4) is positioned beside
pivoted end of the second rib (2) and the third rib (3) instead of
being stopped. Then, the whole rib assembly can be more near to the
shaft (6) that decreases the closed volume of the umbrella
obviously.
[0010] According to the above-mentioned spirit, the third rib (3)
is capable of being formed a bending portion in a reverse
direction, as shown in FIG. 6. Meanwhile, the fourth rib (4) is
also capable of being formed a similar bending portion (41) at
inner end, as in FIGS. 7 and 8. That can decreases the volume more
effectively when the umbrella is closed and folded.
[0011] Hence, the invented structure according to the present
invention obtains obviously improvement and should be allowed for
patent.
