BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a waterproof shelter.
2. Description of the Related Art
A conventional waterproof shelter in accordance with the prior art shown in
FIG. 6
comprises a frame (
66
), a canopy (
60
) mounted on the frame (
66
) and including two first connecting sides (
602
), and two side panels (
61
) each mounted on the frame (
66
) and each including two second connecting sides (
612
) each stitched to one of the two corresponding first connecting sides (
602
) of the canopy (
60
), thereby forming a seam (
63
). The canopy (
60
) is composed of a plurality of first canvas panels (
600
) stitched together, thereby forming a plurality of seams (
604
). Each of the two side panels (
61
) are composed of a plurality of second panels (
610
) which are stitched together, thereby forming a plurality of seams (
614
).
In such a manner, the seams (
63
,
604
and
614
) are easily loosened or torn during long-term utilization, thereby forming leaks in the connection between the canopy (
60
) and the side panels (
61
) such that the shelter is not waterproof. The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional waterproof shelter.
BRIEF SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a waterproof shelter comprising a frame including two elongated first sides and two short second sides; a canopy mounted on the top of the frame and having two elongated first sides and two short second sides; and two elongated side panels each mounted on one of the two corresponding first sides of the frame and each having a top side bonded to one of the two corresponding first sides of the canopy by means of a high frequency heat welding process.
The waterproof shelter further comprises a plurality of retaining rings each secured in the periphery of the canopy, and a plurality of catches each abutting one of the corresponding retaining rings. Each of the catches includes a flexible cord having a first end extending through the respective retaining ring and through the frame, and a loop-shaped second end detachably mounted to the catch.
The waterproof shelter further comprises a plurality of retaining rings each secured in the periphery of each of the two side panels, and a plurality of catches each abutting one of the corresponding retaining rings and each including a flexible cord having a first end extending from the catch through the retaining ring and the frame, and a loop-shaped second end detachably mounted to the catch.
The waterproof shelter further comprises two end connecting panels each having a first side and a second side, the first side securely bonded to one of the two corresponding second sides of the canopy by means of a high frequency heat welding process.
The waterproof shelter further comprises at least one auxiliary sheltering panel mounted on one of the two second sides of the frame, and having a top side secured to the second side of one of the two end connecting panels. Each of the two end connecting panels includes a plurality of first snaps mounted on the second side thereof, and the auxiliary sheltering panel includes a plurality of second snaps mounted on the top side thereof and secured to one of the corresponding first snaps of the second side of the respective end connecting panel.
The waterproof shelter further comprises a plurality of retaining rings each secured in the periphery of the auxiliary sheltering panel, and a plurality of catches each abutting one of the corresponding retaining rings and each including a flexible cord having a first end extending from the catch and extending through the respective retaining ring and the frame, and a loop-shaped second end detachably mounted to the catch.
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.
