Frame structure of an umbrella having two layers of cover
Abstract
The invention relates to a frame structure of an umbrella having
two layers of cover, which includes a main rib and a branch rib,
wherein the main rib is provided with a connector for connecting
with the branch rib and an upward slot, an elastic rib having an
inner loop to be received in the slot and penetrated by a lateral
pin on the connector that the elastic rib is elastic contact with
the main rib. The elastic rib and the main rib are provided for
connecting with the upper cover and the bottom cover while the

Claims
1. A frame structure of an umbrella having two layers of cover
including a main rib and a branch rib, wherein the main rib is
provided with a connector having a pair of downward ears to connect
with one end of the branch rib and an upward slot, an elastic rib
having an inner loop to be received in the slot and penetrated by a
lateral pin on the connector that the elastic rib is elastic
contact with the main rib.

in claim 1, wherein the umbrella can be a straight umbrella or a
collapsible umbrella.
4. A frame structure of an umbrella having two layers of cover
including a main rib and a branch rib, wherein the main rib is
provided with a connector having a pair of downward ears to connect
with one end of the branch rib and an upward slot, an elastic rib
having an inner slider with two side rods to be received in the
slot with two curve grooves.
5. A frame structure of an umbrella having two layers of cover
including a main rib and a branch, rib, wherein the main rib is
provided with a connector having a pair of downward ears to connect

having an inner folded end to be received in the slot and
positioned by a lateral pin of the connector.
Description
BACKGROUND OF THE INVENTION
[0001] As shown in FIG. 1, a normal umbrella having two layers of
cover includes an upper cover (1) and a bottom cover (2). This
umbrella can release wind from a space between the two covers that
prevents the frame of the umbrella from being destroyed. Referring
to FIG. 2 to 4, the traditional frame includes an elastic slice
(3), which connects with a joint (4) to engage with a connector (6)
of a main rib (5). The elastic slice (3) and the main rib (5) are
connecting with the upper cover (1) and the bottom cover (2)
respectively. The conventional frame has an important drawback that
the connecting strength between the joint (4) and the connector (6)
is not enough. When strong wind occurs, the elastic slice (4)
usually releases from the main rib (5) and the frame of the
umbrella is broken.
[0002] The present invention is to provide an improved frame
structure of an umbrella having two layers of cover, which provides
a simple and firm structure for connecting the two covers. 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 perspective view showing a normal umbrella
having two layers of cover.
[0004] FIG. 2 is a plan view showing a traditional umbrella having
two layers of cover.
[0005] FIG. 3 is an exploded perspective view showing parts of the
frame of FIG. 2.
[0006] FIG. 4 is an assembled view of FIG. 3.
[0007] FIG. 5 is an exploded perspective view showing parts of the
frame according to the present invention.
[0008] FIG. 6 is an assembled view of FIG. 5.
[0009] FIG. 7 is a cross-sectional plan view of FIG. 6.
[0010] FIG. 8 is a plan view showing an embodiment on a straight
umbrella according to the present invention.
[0011] FIG. 9 is a plan view showing an embodiment on a collapsible
umbrella according to the present invention.
[0012] FIG. 10 is a cross-sectional plan view showing another
positioning direction of an elastic rib of the frame.
[0013] FIG. 11 is an exploded perspective view showing another
embodiment of a joint according to the present invention.
[0014] FIG. 12 is a cross-sectional plan view of FIG. 11.
[0015] FIG. 13 is a perspective view showing a modified structure
of the elastic rib according to the present invention.
[0016] FIG. 14 is a plan view showing a further embodiment of the
elastic rib according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring to FIG. 5 to 7, the present invention relates to
an umbrella having two layers of cover, which includes a main rib
(5) and a branch rib (7). The main rib (7) is provided with a
connector (8), which has a pair of downward ears (8) to connect
with an end of the branch rib (7) by a pin (10). The connector (8)
has an upper slot (11) with a lateral pin (12). An elastic rib (13)
has its inner end a loop (14) to be placed in the slot (11)
meanwhile the pin (12) also penetrates the loop (14). Hence, the
elastic rib (13) will be elastic contact against the main rib (5).
Under such assembly, the present invention provides the elastic rib
(13) for connecting with the upper cover (1) and the main rib (5)
for bottom cover (2), wherein the connecting strength will be
enough to prevent from releasing therebetween. Moreover, in order
to be convenient a separate of two covers, a ring (15) can be
provided on the main rib (5) near the connector (8). So, the
elastic rib (13) will be kept a small distance from the main rib
(5) for convenience in manufacturing or operating.
[0018] It will be understood that the present invention can be
applied on a straight umbrella, as in FIG. 8, or on a collapsible
umbrella, as in FIG. 9. In the same invented merit, another
position direction of the elastic rib (13), such as in FIG. 10 is
also available. And, as shown in FIG. 14, the elastic rib (13) has
an inner folded end (131) to replace the loop (14) will reach the
same effect and is claimed by this application.
[0019] Please refer to FIGS. 11 and 12; the present invention
includes a modified connector (8), which has the slot (11) up to
the main rib (5). Hence, the elastic rib (13) and the loop (14)
both contact with the main rib (5). FIG. 13 shows a modified
structure of the elastic rib (13), which is provided with a slider
(16) having two side rods (17). The connector (8) is provided with
two curve grooves (18) and the pin (12) is ignored. The slider (16)
can be received in the slot (11) and the sliders (16) are received
in the grooves (18) to obtain a secure connection.
