Abstract
A simple hanging parasol includes a hanging shank, and a parasol body combined beside the shank. The shank has a fix base fixed on top, a slide sleeve fitting movably around the shank. The parasol body has a plurality of ribs, a plurality of spreaders, a canopy, an upper ring, a lower ring, and an elastic pulling member. The ribs have inner ends pivotally connected radially with the upper ring located at the center of the canopy and one outer end pivotally connected with the slide sleeve. The lower ring has a tubular member to fit with a conical insert rod of the upper ring to keep the ribs expanded to support the canopy in expanding the parasol, and to separate from the insert rod in collapsing the parasol to lie along beside the shank. The pulling member pulls the lower ring to let the tubular member of the lower ring automatically fit with the insert rod of the upper ring in expanding the parasol.
Description




BACKGROUND OF THE INVENTION




This invention relates to a simple hanging parasol, particularly to one provided with an upper ring and a lower ring to be automatically fitting with each other in expanding or collapsing a canopy in conjunction with a elastic pulling member provided between the lower ring and one of spreaders, so as to conveniently handle the parasol.




A conventional hanging parasol shown in

FIGS. 1 and 2

, includes a hanging shank


1


and a parasol body


2


supported by the hanging shank


1


. Then the shank has a fix base


11


fixed on top of the shank


1


and a slide sleeve


12


fitting movably around the shank


1


below the fix base


11


. The shank


1


has its lower end fixed firmly on the ground or the like. The parasol body


2


consists of a plurality of ribs


21


, and a plurality of spreaders


22


, an upper ring


24


, and a lower ring


25


and a canopy


23


supported on the ribs


21


. The ribs


21


,


21




a


have their upper ends pivotally connected to the upper ring


24


positioned in the center of the canopy


23


in radial condition, and the upper ring


24


has its lower end connected with a conical insert rod


241


, which has a stop lip


2410


formed in an intermediate portion. The lower ring


25


is located under the upper ring


24


and pivotally connected with inner ends of the spreaders


22


,


22




a


in a radial condition. The spreaders


22


,


22




a


have their outer ends pivotally connected to intermediate portions of the ribs


21


,


22




a


. The lower ring


25


has a tubular base


251


formed to extend upward from an upper end, and the tubular base


251


may be inserted by or separated from the insert rod


241


of the upper ring


24


in case of expanding or collapsing the parasol body


2


.




One of the ribs


21




a


and one of the spreaders


22




a


intercross with each other and pivotally connected with each other, with the outer end of the rib


21




a


pivotally connected with the slide sleeve


12


of the shank


1


, and with the outer end of the spreader


22




a


is pivotally connected with the fix base


11


, as shown in FIG.


1


. Therefore, the rib


21




a


and the spreader


22




a


combine the parasol body


2


with the shank


1


, and prop up the whole weight of the parasol together.




In using the conventional parasol, if the slide sleeve


12


is moved manually down along the shank


1


from an expanded condition shown in

FIG. 1

to a collapsed condition shown in

FIG. 3

, the rib


21




a


may forces the other ribs


21


and all the spreaders


22


,


22




a


swing down to move nearer to the shank


1


and finally lie along the shank


1


in a collapsed condition (as shown in FIG.


3


).




On the contrary, if the slide sleeve


12


is manually moved up along the hanging shank


1


from the collapsed condition to the expanded condition, forcing the tubular base


251


insert in the insert base


241


, with the upper end of the tubular base


251


contacting (or stopped by) the stop lip


2410


to let the canopy


23


expanded on the ribs


21


,


21




a


. Then the conventional hanging parasol is completely expanded for use, as shown in FIG.


1


.




However, the conventional hanging parasol has been found to have a drawback that the upper ring


24


and the lower ring


25


often cannot align to each other as to fit with each other in an expanding course. Then another person has to help correct the upper and the lower ring


24


and


25


to align to each other in fitting with each other. Thus, a user cannot use the conventional hanging parasol without assistance of another person, quite inconvenient.




The cause of the drawback of the conventional hanging parasol is to be described. As shown in

FIG. 4

, the whole weight of the conventional hanging parasol is supported only one of the ribs


21




a


and one of the spreaders


22




a


connected with the hanging shank


1


, in a suspended condition. So when the slide sleeve


12


is moved nearer to the upper end of the shank


1


and to expand the canopy


23


, the whole parasol is located at the farthest from the shank


1


, in other words, the whole parasol is at the farthest distance from the shank


1


, and all the ribs


21


and all the spreaders


22


may sag to make the upper ring


24


and the lower ring


25


all tilted for an angle. Then the lower ring


25


is supported by the spreader


22


A in a horizontal condition, and liable to tilt outward from the shank


1


. But the upper ring


24


is supported by the sloped rib


21




a


, and liable to tilt toward the shank


1


as shown in FIG.


4


A. So the tilting directions of the upper and the lower ring


24


and


25


are opposite to each other, impossible to the both


24


and


25


fit with each there. However, a user has to slide up the slide sleeve


12


with one hand and to grip the shank


1


with the other hand, impossible to adjust the upper and the lower rings


24


and


25


. Then the user needs another person to help adjust them to fit with each other as shown in

FIGS. 1 and 2

, making up an annoying problem.




SUMMARY OF THE INVENTION




This invention has been devised to offer a simple hanging parasol expansible by only one person, with an upper and a lower ring automatically fitting with each other and thus convenient to use.




The feature of the invention is an elastic pulling member provided to have its outer end hooked with one spreader pivotally connected to a fix base fixed on top of a hanging shank. When the parasol is expanded from a collapsed condition to an expanded condition by manually moving up a slide sleeve fitted movable around the hanging shank, the slide sleeve moves up that spreader with other spreaders and all ribs supporting a canopy, and the ribs have inner ends pivotally connected to an upper ring located at the center of the canopy and intermediate portions pivotally connected with outer ends of the spreaders expanded to the expanded condition, with help of the elastic pulling member automatically resiliently let a tubular member of a lower ring pivotally connected with inner ends of all spreaders to fit with a conical insert rod of the upper ring so as to keep the parasol in the expanded condition stably.

, and a elastic pulling member


3


combined together. The hanging shank


1


has a fix base


11


fixed on top, and a slide sleeve


12


fitting movable around the shank


1


a little below the fix base


11


,




The parasol body


2


consists of a plurality of ribs


21


, a plurality of spreaders


22


, and a canopy


23


, an upper ring


24


positioned at the center of the canopy


23


, and a lower ring


25


positioned under the upper ring


24


, and the elastic pull member


3


.




The ribs


21


have their inner ends pivotally connected with the upper ring


24


in a radial condition. One of the ribs


21




a


is specially and pivotally connected with the slide sleeve


12


so as to be expanded or collapsed. The upper ring


24


has a conical insert rod


241


formed to extend down. The canopy


23


is laid to cover all the ribs


21


,


21




a


. The spreaders


22


have their inner ends pivotally connected with the lower ring


25


in a radial condition. One of the spreader


22




a


is specially elongate and has its outer end pivotally connected with the fix base


11


and intercrosses and pivotally connected with the rib


21




a


as shown in FIG.


5


. Further, the other spreaders


22


have their outer ends pivotally connected to intermediate portions of the related ribs


21


. The lower ring


25


has a tubular base


251


formed to extend upward for the conical insert rod


241


to fit therein in case of the parasol expanded and separate from the conical insert rod


241


in case of the parasol collapsed. The rib


21




a


is pivotally connected with the slide sleeve


12


as described above. The spreader


22




a


extends to protrude out of the canopy body


23


and connected pivotally with the fix base


11


. Thus the rib


21




a


and the spreader


22




a


both support the weight of the canopy


2


.




The pull member

is elastic, having an outer end hooking the spreader


22




a


and an inner end hooking the tubular base


251


of the lower ring


25


, as shown in

FIGS. 5 and 6

.




In handling the simple hanging parasol, referring to

FIGS. 7A and 7B

, when a user expands it, the user manually pushes the slide sleeve


12


in a collapsed position up along the hanging shank


1


, with the pull member


3


pulling the lower ring


25


upward to become gradually vertically straight to the shank


1


, as shown in FIG.


7


A. Then the upper opening of the tubular base


251


of the lower ring


25


is automatically aligned to the conical insert rod


241


and gradually moving up to fit with insert rod


241


to complete expanding of the simple hanging parasol with no assistance of another person.





FIG. 8

shows another embodiment of a simple parasol, almost the same structure as the preferred embodiment described above, with the difference that the connecting line of the upper and the lower ring


24


, and


25


is higher than the pivotal point of the rib


21




a


and the spreader


22




a


in an expanded position. This embodiment has the same function as the above mentioned preferred embodiment.




While the preferred embodiment of the invention has been described, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all the modifications that fall within the spirit and scope of the invention.
