BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ventilated umbrella.
2. Description of the Related Art
A first conventional ventilated umbrella in accordance with the prior art shown in
FIG. 5
comprises a support frame (
40
) having a plurality of ribs (
41
), and a composite canopy (
3
) attached to the support frame (
40
). The composite canopy (
3
) includes a main canopy (
30
) attached to the ribs (
41
) of the support frame (
40
) and contains a plurality of openings (
301
), and an auxiliary canopy (
31
) mounted on the main canopy (
30
) to cover the openings (
301
). In such a manner, air is able to flow through the gap defined between the main canopy (
30
) and the outer edge (
311
) of the auxiliary canopy (
31
) into the openings (
301
), thereby enhancing the ventilation effect of the umbrella.
However, the auxiliary canopy (
31
) snugly abuts the main canopy (
30
) when the support frame (
40
) is fully expanded such that the gap between the main canopy (
30
) and the outer edge (
311
) of the auxiliary canopy (
31
) is too small to allow the air access to the openings (
301
), thereby decreasing the ventilation effect. In addition, the auxiliary canopy (
31
) significantly overlaps the main canopy (
30
), thereby increasing the cost of manufacturing.
A second conventional ventilated umbrella in accordance with the prior art shown in
FIG. 6
comprises a support frame (
60
) having a plurality of ribs (
61
), and a composite canopy (
5
) attached to the support frame (
60
). The composite canopy (
5
) includes a main canopy (
50
) attached to the ribs (
61
) of the support frame (
60
) and containing therein an opening (
500
) in which a net (
501
) is mounted, and an auxiliary canopy (
51
) mounted on the main canopy (
50
) to cover the net (
501
). In such a manner, air is able to flow through the gap defined between the main canopy (
50
) and the outer edge (
511
) of the auxiliary canopy (
51
) into the net (
501
), thereby enhancing the ventilation effect of the umbrella.
However, the auxiliary canopy (
51
) snugly abuts the main canopy (
50
) when the support frame (
60
) is fully expanded such that the gap between the main canopy (
50
) and the outer edge (
511
) of the auxiliary canopy (
51
) is too small to allow the air access to the net (
501
), thereby decreasing the ventilation effect. In addition, the auxiliary canopy (
51
) significantly overlaps the main canopy (
50
), thereby increasing the cost of manufacturing.
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional ventilated umbrella.
BRIEF SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a ventilated umbrella comprising a support frame forming a tetragonal surface, a first canopy secured on the tetragonal surface of the support frame and having an outer edge, a loopshaped second canopy secured on the tetragonal surface of the support frame and having an inner edge located under the outer edge of the first canopy, a gap defined between the first canopy and the second canopy, and a plurality of elastic members each having a first end secured to the support frame, and a second end secured to the inner edge of the second canopy.
The first canopy has a dimension smaller than the tetragonal surface of the support: frame.
The support frame includes a shaft, and a retaining ring secured on the shaft, and the first end of each of the elastic members is attached to the retaining ring. The retaining ring contains a plurality of locking holes therein, and the first end of each of the elastic members includes a locking hook secured in one of the locking holes.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
