Claims:

I claim:



1. A reinforcement structure for sun tent extension canopy comprising a pair of awning poles covered with a canopy, and a side pole, each said awning pole having a extension frame at the top portion thereof, each said extension frame comprising an extension pole, a supporting pole, a reinforcing pole and clamps, wherein said extension pole having one end connected to the top portion of said awning pole, and said supporting pole having also one end connected to the lower portion of said awning pole, and the improvements comprising said extension pole comprising a pair of clamps and a receptacle, said side pole comprising also a receptacle corresponding to said receptacle of said extension pole, said reinforcing pole comprising a stretch cord adapted to connect to said receptacles; by means of inserting the two ends of said reinforcing pole into said receptacles of said extension pole and said side pole to reinforce the extension canopy from retracting, and said stretch cord of said reinforcing pole being adapted to tie said reinforcing pole to said extension pole with clamps when folding said tent to prevent said reinforcing pole from disappearing.

2. The reinforcement structure for sun tent extension canopy, as recited in claim 1, wherein said reinforcing pole comprises stretch cords at both ends to be tightened to said two receptacles, and to tie said reinforcing pole on said side pole when folding said tent.

Description:

FIELD OF THE INVENTION

[0001] This invention relates to a reinforcement structure for sun tent extension canopy, more particularly to a structure to support a canopy extending from the tent.

[0002] Due to the busyness and tension of our daily life, outdoor activities have been popular for many people and families to relax their stress from work and also to have a chance to breathe the natural air. However, many of the outdoor facilities have no roof or covers, people have to either stay under the sun or bring their tent to provide a shady area.

[0003] A conventional tent can cover a limited area only and it may shake when the wind blows. In view of this, the inventor has invented the present invention to improve the shortcomings.

SUMMARY OF THE INVENTION

[0004] It is the primary object of the present invention to provide a reinforcement structure for sun tent canopy, which is steady under wind.

[0005] It is another object of the present invention to provide a reinforcement structure for sun tent canopy, which is easy to install and to dismount.

[0006] It is a further object of the present invention to provide a reinforcement structure for sun tent canopy, which is inexpensive in manufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A reinforcement structure for sun tent canopy of the present invention, as shown in FIGS. 1 and 2, comprises a pair of extension frames 2 connected to the top of two sides of the awning poles 11 of the tent 1. Each extension frame 2 is composed of an extension pole 21, a supporting pole 22, a pair of clamps 23 and 24 and a reinforcing pole 4.

[0016] Each extension pole 21 has one end connected to the top end of the awning pole 11 while the other end of which is connected to an end of the supporting pole 22 which then has its other end connected to the pole 11. In such way that the extension pole 21, the pole 11 and the supporting pole 22 forms a triangle to support the extension pole 21, which is secured with the a pair of clamps 23 and 24 at center portion facing outwardly thereof. A receptacle 3 is formed inward of the extension pole 21 with a socket 31 thereat for receiving another end of the reinforcing pole 4. For the reinforcing pole 4 to insert with one end therein, the reinforcing pole 4 has a stretch cord 5 which connects the reinforcing pole 4 to the socket 31, as shown in FIG. 3. Another receptacle 3A is formed on a side pole 12 inwardly corresponding to the receptacle 3 on the extension pole 21.

[0017] To assemble, the two ends of the reinforcing rod 4 are inserted into the sockets 31 and 31A of the receptacles 3 and 3A, respectively. The extension pole 21 is stretched so that when a canvas 14 is placed on the extension poles 21, the canvas 14 will remain in a flat and stretch status. Whereas the reinforcing pole 4 will hold the canvas 14 at place and prevent the canvas 14 from retreating back to its original position.

[0018] To fold the canopy 14, as shown in FIGS. 3 and 4, the reinforcing poles 4 is dismounted from the receptacle 3 and is tied to the extension pole 21 with the stretch cord 5, whereas the reinforcing poles 4 is secured by the clamps 23 and 24 as well. FIG. 5 has shown a folded tent that the extension pole 21 and the supporting pole 22 are both folded towards the awning pole 11 of the tent 1.

[0019] Another embodiment is shown as FIGS. 6 and 7, wherein the side pole 13 replaces the side pole 12 of the above. The reinforcing pole 4 with the stretch cord 5 is secured at its two ends to the sockets 31 and 31B of the receptacles 3 and 3B of the extension poles 21 and the side pole 13. To dismount, as shown in FIG. 8, the two ends of the reinforcing pole 4 are retracted from the receptacles 3 and 3B, due to the stretch cord 5 is connected to the receptacles 3 and 3B, the reinforcing pole 4 will be located next to the awning pole 11. To mount the tent 1, the extension frame 2 and the side poles 12 and 13 are stretched, and then the reinforcing pole 4 is inserted into the two receptacles 3 and 3B.
