Reinforced umbrella for resisting wind
Abstract
The invention relates to a reinforced umbrella for resisting
wind. The umbrella mainly includes a first rib to connect with a
branch rib having its outer end a sleeve being provided around a
tail rib slidably. The branch rib can increase the strength that
prevents the tail rib from being bent sideward to resist wind when
the umbrella is opened. The umbrella is then avoided from damage
for utilization.

Claims
1. A reinforced umbrella for resisting wind including a first rib
and a tail rib, both of which are connected by a connector; the
character is to provide a branch rib, which has an inner end
connected with the first rib and has a sleeve provided around the
tail rib slidably, the tail rib having a ring for positioning the
sleeve of the branch rib when the umbrella is opened; the first rib
having its outer end as a fork end for placing both sides of the
connector, which is totally received between the fork end.
2. The reinforced umbrella for resisting wind as claimed in claim
1, wherein the lower plane of the connector is almost laid on
bottom of the U-shape groove.
Description
BACKGROUND OF THE INVENTION
[0001] Referring to FIG. 1 and 2, a conventional folded umbrella
has a connector (3) to connect a first rib (1) and a tail rib (2).
When wind blows, the tail rib (2) would be bent upward (as imaged
line of FIG. 1) or bent sideward (as imaged line of FIG. 2). At
this moment, the most bearing position will be on the connecting
point of the tail rib (2) and the connector (3), in which it is
broken easily and then the umbrella can't be used. There is a know
improved umbrella, which provides the connector (3) with a
projection (31) to insert into a U-shape groove of the first rib
(1), as shown in FIG. 3 for preventing the tail rib (2) from
sideward bending. Since it is only a point contact therebetween,
reinforced effect is still poor.
[0002] The present invention is to provide a reinforced umbrella
for resisting wind, which includes a branch rib extending to
connect with the tail rib that increases perfect strength for
resisting wind effectively. Now, accompanying with the following
drawings, the character of the present invention will be described
here and after.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] FIG. 1 is a front plan view showing a conventional folded
umbrella.
[0004] FIG. 2 is a top plan view showing the conventional folded
umbrella.
[0005] FIG. 3 is a front plan view showing an improved traditional
folded umbrella.
[0006] FIG. 4 is a perspective view showing a set of frame of a
reinforced umbrella for resisting wind according to the present
invention.
[0007] FIG. 5 is a front plan view showing the reinforced umbrella
according to the present invention.
[0008] FIG. 6 is a top plan view of FIG. 5.
[0009] FIG. 7 is a front plan view showing the reinforced umbrella
in closing state.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] Referring to FIG. 4 to 6, the present invention relates to a
reinforced umbrella, which includes a first rib (1) and a tail rib
(2), both of which are connected by a connector (3). A main
character of the present invention is to provide a branch rib (4),
which has an inner end connected with the first rib (1) and has a
sleeve (41) provided around the tail rib (2) slidably. The tail rib
(2) has a ring (21) for positioning the sleeve (41) of the branch
rib (4) when the umbrella is opened. Moreover, the first rib (1)
has its outer end as a fork end (11) for placing both sides of the
connector (3). Hence, the connector (3) is totally received between
the fork end (11) and the lower plane of the connector (3) is
almost laid on bottom of the U-shape groove. By use of the large
contact engagement to reinforce the strength, the connector (3)
will be avoided from damage when the tail rib (2) is bent sideward.
When closing the umbrella, as shown in FIG. 7, the sleeve (41) can
be slid downward alone the tail rib (2) without any trouble that
the umbrella can be used as normal.
[0011] From above mention, it can be understood that the branch rib
(4) can increases the strength for the tail rib (2) to prevent from
damage as being bent upward in FIG. 1. The fork end (11) of the
first rib (1) snaps the connector (3) that avoids the tail rib (2)
being bent sideward to prevent from broken. Obviously, the present
invention obtains utilization and effect of resisting wind.
[0012] Accordingly, the above-mentioned structure is only an
exemplary of the present invention. Any modification with the same
merit is still claimed in this application; such as to apply any
similar structure on three folded umbrella or more.
