Parasol
Abstract
A parasol includes a parasol shaft having a plurality of parasol
ribs provided radially and movably on top. The parasol ribs are
provided on top with a parasol cover made of a number of parasol
gores. The feature is that each parasol rib has its outermost end
formed into a lower curved receiving portion. Thus, when the
parasol cover is spread out on the parasol ribs, the lower portion
of the parasol cover on the lower curved receiving portions of the
parasol ribs will naturally curve down along the receiving portions
and make up a suspending lower portion, simplifying the process of
cutting the parasol gores and sewing them together into the parasol
cover, and obtaining an effect of blocking off sunlight.

Claims
I claim
1. A parasol comprising a parasol shaft, said parasol shaft fixedly
provided with a plurality of parasol ribs arranged radially and
movably on top, said parasol shaft fitted with a sliding sleeve, a
plurality of stretchers pivotally connected at one end with said
sliding sleeve, said stretchers having the other ends respectively
connected with an intermediate portion of each said parasol rib,
said parasol ribs provided on top with a parasol cover made of a
plurality of parasol gores: and, Characterized by each said parasol
rib having its outermost end extending downward to make up a lower
curved receiving portion, said parasol cover naturally curving down
along said lower receiving portions of said parasol ribs and
forming a suspending lower portion.
Description
BACKGROUND OF THE INVENTION
[0001] This invention relates to a parasol, particularly to one
convenient to have its parasol gores cut and together sewed into a
parasol cover, facilitating producing and having an aesthetic
appearance.
[0002] The structure of a conventional parasol, as shown in FIG. 1,
includes a parasol shaft 10 having a plurality of parasol ribs 30
provided radially on top. A number of stretchers 40 are
respectively connected at one end pivotally with the intermediate
portion of each parasol rib 30, and at the other end connected with
a sliding sleeve 401 fitted around the parasol shaft 10. Then, a
parasol cover 20 made of a number of parasol gores is fixed on the
top of the parasol ribs 30. Thus, when the sliding sleeve 401 is
pushed upward, the stretchers 40 are synchronously stretched
outward to make the parasol ribs 30 and the parasol cover 20 spread
outward together, as shown in FIG. 1. Besides, a number of
suspending lower portions 201 of the parasol cover 20 protruding
out of the ends of the parasol ribs 30 are preset around the
circumferential edge of the parasol cover 20 in order to acquire a
comparatively good effect of blocking off sunlight, because the
suspending lower portions 201 will drop down to act as a sunshade
when the parasol cover 20 is spread outward.
[0003] However, such a design of the suspending lower portions 201
cause much trouble in the process of making a conventional parasol.
As the parasol ribs 30 are shaped straight, an extra length of each
parasol gore exceeding the length of the parasol rib 30 has to be
preset when the parasol gore is cut in shape so as to make up a
suspending lower portions 201 around the circumferential edge of
the parasol cover 20. Then, these parasol gores are sewed together
to make up an integral parasol cover 20. The drawback of such a
design is that a sewed joint between every two neighboring
suspending lower portions 201 may be creased and spoil an integral
aesthetic appearance in case the abutting sides of every two
parasol gores are sewed together closely and tightly.
[0004] To solve such a problem, each suspending lower portion 201
has its opposite sides cut in an arcuate shape, as shown in FIGS. 1
and 2, letting the width of each suspending lower portion 201
becomes somewhat smaller than that between the outermost ends of
two parasol ribs 30 stretched outward. Thus, after the parasol
gores are sewed into a parasol cover 20, with the abutting
suspending edges 201 not yet sewed together, the parasol cover 20
is formed to have an inverted U-shaped recess 202 at the outermost
end of each parasol rib 30, enabling each suspending lower portion
201 between every two neighboring parasol ribs 30 to drop down
naturally, causing no crease.
[0005] Nevertheless, the way of cutting the opposite sides of each
suspending lower portion 201 in an arcuate shape and sewing them in
an inverted U-shaped recess 202 increases difficulty in setting up
patterns for parasol gores and cutting them in shape. Further,
during sewing, it is necessary to turn over the angles of the
parasol gores time after time in order to match with the shape of
the inverted U-shaped recesses 202, and at the same time watch if
the joint between two neighboring suspending lower portion 201 is
neat and smooth, thus increasing more difficulty in sewing.
SUMMART OF THE INVENTION
[0006] The objective of the invention is to offer a parasol
convenient to have its parasol gores cut and sewed together into a
parasol cover, and having effect of facilitating producing. The
parasol of this invention includes a parasol shaft having a
plurality of parasol ribs provided radially on top, with the
parasol ribs provided on top with a parasol cover made of numerous
parasol gores. The feature of the invention is that each parasol
rib has a lower curved receiving portion in an outermost end. Thus,
when the parasol cover is spread on the parasol ribs, the parasol
cover on the lower receiving portions of the parasol ribs will
naturally drop down and form a suspending lower portion
BRIEF DESCRIPTION OF DRAWINGS
[0007] This invention will be better understood by referring to the
accompanying drawings, wherein:
[0008] FIG. 1 is a perspective view of a conventional parasol:
[0009] FIG. 2 is a partially perspective view of the conventional
parasol:
[0010] FIG. 3 is a perspective view of a parasol in the present
invention:
[0011] FIG. 4 is a side view of a parasol rib of the parasol in the
present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] A preferred embodiment of a parasol in the present
invention, as shown in FIG. 3, includes a parasol shaft 1 having a
plurality of parasol ribs 3 provided radially and movably on top.
Each parasol rib 3 is pivotally connected with one end of a
stretcher 4 on an intermediate portion, and the stretcher 4 has its
other end connected with a sliding sleeve 41 around the parasol
shaft 1. The feature of the invention is that each parasol rib 3
has its outermost end curving downward and forming a lower curved
receiving portion 31, as shown in FIG. 4.
[0013] By so designing, the parasol cover 2 has its circumferential
edge kept in an integral shape and naturally formed into a
suspending lower portion 21 curving down along the lower receiving
portions 31 of the parasol ribs 3 after it is mounted on the
parasol shaft 1 and the parasol ribs 3.
[0014] To sum up, the design for making a parasol in the present
invention can not only simplify the process of setting up patterns
for parasol gores and cutting them in shape, but also simplify the
steps of sewing the parasol gores into a parasol cover 2 and keep
the suspending lower portion 21 naturally curving down to serve as
a sunshade.
[0015] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
