Description
Title: CANOPY FRAME FOR UMBRELLA OF VARIOUS SHAPES
BACKGROUND OF THE INVENTION
The present invention relates to an improved canopy frame for use on umbrellas which have their canopies structured in various shapes, making the external appearance of umbrellas dexterous, attractive and interesting. The frame is comprised of a main shaft, an upper sliding notch, a lower sliding notch, multiple positioning ribs, multiple upper spreaders, multiple upright ribs, multiple upper angle-forming clamps, multiple auxiliary stretchers, multiple lower spreaders and multiple clamping pieces.
There are two positioning holes on the main shaft for the fixing of the upper and lower sliding notch and at the top end of the main shaft is disposed the fixed notch. The upper and lower sliding notch mounted consecutively on the main shaft under the fixed notch.
One end of each positioning rib is connected to the fixed notch and the other end is associated with an end hinge point of an upper angle-forming clamp. One end of each upper spreader is fixed to the upper sliding notch and the other end is engaged with the I5 middle hinge point of an upper angle-forming clamp. One end hinge point of each angle-forming clamp is coupled to one end of each upright rib to which is mounted a clamping piece at the other end. The upright rib has a hinge projection at one end to which one end of each auxiliary rib is connected and the other end is fixed to an end hinge point of a lower angle-forming clamp, and each lower angle-forming clamp is associated with a folding rib. Thereby when a canopy is mounted to the frame, umbrellas of various shapes can be obtained.
The improved canopy frame is easily converted into different kinds of shapes so as to make umbrellas produced in dexterous forms for commercial advertisements or just to be used as common umbrellas, which can better protect people from getting wet by rain.
In general, common umbrellas are all made to have a simple canopy frame including a main shaft on which a runner is slidably moved to get a frame to stretch open, and a canopy attached to the frame is extended in an arch shape without any variations for decades. Such a structure is not ideal enough to permit commercial advertisements to be printed on the canopy is one aspect, and such an umbrella is not good enough to protect a person under the umbrella from getting wet by rain cast in slant directions.

One end hinge point 52 of each angle-forming clamp 50 is coupled to one end of each upright rib 42 to which is mounted a clamping piece 70 at the other end with a section of the upright rib 42 extended further downwardly. Each lower spreader 60 slightly shorter than each positioning rib 40 has one end connected to the lower sliding notch 30 and the other end coupled to the middle hinge point 71 of a clamping piece 70. A canopy is mounted to the frame to obtain a cone shaped umbrella.
Referring to Fig.7, a fifth embodiment of a common umbrella with a wide brimmed type of the present invention is illustrated. The frame is comprised of a main shaft 10, 1 S an upper sliding notch 20, a lower sliding notch 30, eight positioning ribs 40, eight upper spreader 41, eight upright ribs 42, eight upper angle-forming clamps 50, eight lower spreaders 60 and eight clamping pieces 70. There are two positioning holes (not shown) on the main shaft 10 for the fixing of the upper and lower sliding notch 20, 30 and at the top end of the main shaft 10 is disposed the fixed notch 11. The upper and lower sliding notch 20, 30 mounted consecutively on the main shaft 10 under the fixed notch 11.
One end of each positioning rib 40 is connected to the fixed notch 11 and the other end is associated with an end hinge point 52 of an upper angle-forming clamp 50. One end of each upper spreader 41 is fixed to the upper sliding notch 20 and the other end is engaged with the middle hinge point 51 of the upper angle-forming clamp 50. One remaining end hinge point 52 of each angle-forming clamp 50 is coupled to one end of each upright rib 42 to which is mounted a clamping piece 70 at the other end with a section of the upright rib 42 extended further downwardly. Each lower spreader 60 has one end s connected to the lower sliding notch 30 and the other end coupled to the middle hinge point 71 of a clamping piece 70. When extended, the lower spreaders 60 stretch the upright ribs 42 outwardly in a slant manner, just like a common umbrella. A
canopy is mounted to the frame to obtain an umbrella with a wide brimmed shape.
Referring to Fig. 8, another embodiment of an umbrella with a wide brimmed type of the present invention is illustrated which comprises a main shaft 10, an upper sliding notch 20, a lower sliding notch 30 having a slidable notch 31 and a spiral spring 32, eight positioning ribs 40, eight upper spreader 41, eight upright ribs 42, eight upper angle-forming clamps 50, eight lower spreaders 60, eight pulling spreaders 61 and eight clamping pieces 70. On top of the main frame 10, there is a fixture notch 11 to facilitate installation of the upper sliding notch 20 and the lower sliding notch 30 on the main frame 10, the spiral spring 32 is sleeved in between the lower sliding notch 30 and the slidable notch 31, one end of each positioning rib 40 are connected to the fixture notch 11 while the other end connected to the upper angle-forming clamps 50, respectively. The upper spreader 41 having also one end connected to the middle hinge point 51 of the upper angle-forming clamp 50 which has its end hinge point 52 connected to the upright ribs 42. The upper position of the upright ribs 42 are secured with the clamping pieces 70. The lower spreaders 60 has one end connected to the lower sliding notch 30 while the other end connected to the middle hinge point 71 of the clamping piece 70. The pulling spreaders 61 are connected with their lower ends to the lower sliding notch 30, respectively, while the ocher ends of which are connected to the middle hinge point 71 of the clamping piece 70. The pulling spreads 61 has one ends connected to the inner centered position of the lower spreaders 60, while the other ends of the pulling spreads 61 are connected to the upper position of the slidable notch 31.
By means of the elastic force of the spiral spring 32, the canopy frame will be open, and the lower spreaders 60 push the eight upright ribs 42 outwardly in an inclined position.
Mounting a canopy on the frame and a wide brimmed umbrella is formed.
It can be apparently seen that the canopy frames of the present invention have the following advantages in practical use:
The main shaft 10 is provided with an upper sliding notch 20 and a lower notch and the positional variation of the upper angle-forming clamps 50, the lower angle-forming clamps 90 and the clamping pieces 70, and the length of each kind of ribs and spreaders, umbrellas of various kinds of shapes can be produced;
2. The upright ribs 42 and the folding ribs 81 can be downwardly extended in a vertical manner, permitting the periphery of an umbrella to be better protected from rain cast in slant directions.
