Abstract
An air charged appliance includes an air chamber and an air sac, made in various shapes for different uses. The air sac is placed in the air chamber and filled up with air to become inflated together with the air chamber, but the both are made separately from each other. The air chamber is not easy to break and able to endure bumping so the air charged appliance can be used for a long period of time.

- A preferred embodiment of an air charged appliance in the present invention, as shown in FIGS. 3 and 4, includes an
air chamber 2 and anair sac 3 combined together. - The
air chamber 2 has an interior space for receiving theair sac 3. Theair chamber 2 is made of special nylon of high danier uneasy to break and able to endure bumping. Theair chamber 2 has a fill opening 21 for theair sac 3 to be pushed in therethrough, and thefill opening 21 is provided with a fasteningmember 22 such as a velcro band or a zipper. Before filled with air, theair sac 3 is put into theair chamber 2 and then pumped in with air to become inflated together with thegas chamber 2. Separated from theair chamber 2, which is able to endure bumping, theair sac 3 itself can prevent leaking. - Each
air chamber 2 can receive oneair sac 3, as shown in FIGS. 3 and 4, or one ormore air sacs 3, and eachair sac 3 is provided with anair valve 30 for filling in air independently. Thus, when the air charged appliance is used as a toy swimming pool or a raft, and should one of theair sacs 3 be broken, the circumferential wall of the toy swimming pool or the raft would not collapse, keeping the toy swimming pool or the raft functioning normally and ensuring the users' safety. - In addition, the size of the interior space of the
air chamber 2 may be made a little smaller than theair sac 3 so that the inflating size of theair sac 3 can be limited to prevent pump too much air so as to keep theair sac 3 elastic. - Another preferred embodiment of the air charging device used as the obstacle (A) of an amusement course in the present invention, as shown in FIGS.5-13, includes an
air chamber 2 and anair sac 3. Theair chamber 2 is provided with a plurality of nail-fastening rings 4 at the lower ends forfixing nails 40 to pass therethrough respectively and then nailed tightly into soft ground to stabilize the obstacle (A). - In case the obstacles (A) for an amusement course is to be positioned on a hard ground such as a concrete ground, the
air chamber 2 can be additionally provided with areceiving space 23 in the bottom to be filled in withheavy matter 24 such as liquid shown in FIG. 7, wooden planks shown in FIG. 8, stones shown in FIG. 9, or the like so long as it (they) can secure the obstacle (A) in position, regardless of the heavy matter made of any material. - Furthermore, the air-filled obstacles (A) can be made in any solid shapes such as a solid square shown in FIG. 10(A), or a solid triangle shown in FIG. 10(B), or a solid arch shown in FIG. 10(C), or a safety obstacle with a
net surface 25 shown in FIGS. 11 and 12, or a golf ball-receivingnet 26 or a volley ball net, as shown in FIG. 13. If the air-filled obstacle (A) together with anet surface 25 is used as a safety obstacle or as a ball-receivingnet 26, it can be fixed on the ground by means of a plurality ofbases - Evidently, the air charging device of the invention has its
air sac 3 filled in with air to become inflated together with theair chamber 2, and the air inside theair sac 3 can hardly leak out, enabling the obstacle (A) maintain its shape and function normally. - One more preferred embodiment of an air charging device used as a children's swimming pool (B) or a raft in the present invention, as shown in FIGS.14-19, includes a
body 5 andair chambers 2. Thebody 5 can be employed as the bottom of a swimming or a playing pool to be filled with a large amount of water, or as a receiving groove of a no-power raft for carrying persons to move on the water by paddling, as shown in FIG. 19, with the raft also possible to be provided with power. Thebody 5 is provided with a plurality of fastening members 51 (Velcro bands preferably), as shown in FIGS. 14-16. - Then, the
body 5 may be provided inside withair chambers 2, and eachair chamber 2 has a fasteningmember 6 at a proper position, as shown in FIG. 17. After thebody 5 receives theair chambers 2 and covers up part of them, the fasteningmembers 51 of thebody 5 and the fasteningmembers 6 of theair chambers 2 are combined together to make up a toy swimming pool or a raft. Besides, theair chamber 2 can be composed ofseveral air chambers air chamber plural air chambers - Moreover, the toy swimming pool or the raft in this invention can be made in various shapes, as shown in FIGS. 18A, 18B and19, therefore the
body 5 is not necessarily to be made in a definite shape. - Still one more preferred embodiment of an air charging device used as a water-stopping wall in the present invention, as shown in FIGS.20-25, includes an
air chamber 2 and aframe 7. - The
frame 7 is formed with anupper side 70, afront side 70 and arear side 70 respectively having a large number ofribs 700 arranged crosswise. Whether theribs 700 are arranged densely or thinly depends on practical needs, and they are provided to confine the inflation direction of theair chamber 2 so as to fix it at a definite location. Then, the adjacent sides of theframe 7 are movably connected together by means of bindingmembers 71 to make theframe 7 collapsible, as shown in FIG. 21. - Additionally, the
frame 7 has anopen side 72 at opposite ends for theinflated air chamber 2 to expand out therethrough. Theframe 7 is provided with a plurality ofhooks 73 at the bottom to engage with the hook rings 74, which are fixed and somewhat hidden on the ground so as to stably keep theframe 7 in place, with the hook rings 74 not protruding out of the ground. Theframe 7 is further formed with anair chamber space 75 in the interior for receiving theair chamber 2. - In using, as shown in FIG. 23, the
air chamber 2 is deposited in theair chamber space 75 of theframe 7 and then theair chamber 2 is filled up with air to become inflated and forced to move toward the oppositeopen sides 72 of theframe 7. As the size of theinflated air chamber 2 is a little larger than theair chamber space 75, theinflated air chamber 2 will expand outward and closely push against theground 8 and theopposite walls 9. Besides, theair chamber 2 is filled with air or air and liquid so it can completely and tightly push against the ground or the walls even if they are uneven, thus able to prevent water from getting into a basement or a room. - While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
