DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0024] The present invention provides a retractable inflatable product, mainly comprising: an inflatable body, a gas charging device communicated with the inflatable body and used to charge the inflatable body with gas, a wire positioning component disposed on the inner wall of the inflatable body, at least one wire 3, and a pay-off and take-up device, which is connected to at least one end of the wire, and pays off the wire during inflation and spreading of the inflatable body and takes up the wire during deflation and retraction of the inflatable body through the wire positioning component.

[0025] FIG. 1.about.FIG. 3 show an embodiment of the present invention, comprising an inflatable body 1 in a shape of snowman, a wire positioning component 2 with a plurality of hollow annular elements 2a.about.2o disposed on the inner wall of the inflatable body 1, a wire 3 passing through all hollow annular elements 2a.about.2o of the wire positioning component 2 shown in FIG. 2 in turn according to the arrow direction shown in FIG. 3, and a pay-off and take-up device 5, including a pay-off and take-up wheel 52 on which the two ends A and B of wire 3 are fixed.

[0026] Alternatively, one end of the wire 3 is fixed on the pay-off and take-up wheel and the other end may be fixed on any appropriate position of the inflatable body or the pay-off and take-up device. Generally speaking, when only one wire is adopted, the head end of the wire 3 may be fixed on the inner wall of the inflatable body 1 close to the pay-off and take-up device 5, or the middle part of the wire is fixed on the inner wall of the top end of the inflatable body 1 and both ends of the wire 3, i.e.: head end and tail end, are connected to the pay-off and take-up device 5. When multiple wires are adopted, the head ends of these wires may be fixed at a same point, on the inner wall of the top end of the inflatable body 1 for example. Of course, different points are also feasible. Alternatively, the middle parts of these wires are fixed to any point of the inner wall of the inflatable body 1, for example the symmetry point or symmetry axis of the inflatable body 1 and then the head ends and tail ends of these wires 3 are all connected to the pay-off and take-up device 5.

[0027] The foregoing wire positioning component 2 may adopt different materials or shapes according to different demands. For example, in an embodiment of the present invention, the wire positioning component 2 is formed by enclosing of metal bars or plastic bars; in another embodiment of the present invention, the wire positioning component 2 is constituted by a through hole disposed on cloth strips and the cloth strips are connected to the inner wall of the inflatable body 1. The fabric of the cloth strips may be woven fabric, knitted fabric or leather. The present invention has no limitation to this. In order to strengthen the firmness of the through hole, hemming may be adopted on the circumference of the through hole. The material of the hem may be metal, plastic or fabric, etc. When cloth strips are adopted for the wire positioning component 2, a plurality of cloth strips may be disposed inside an inflatable body and at least one hollow annular element may be disposed on each cloth strip, 3 for example.

[0028] The foregoing pay-off and take-up device 5 may be located inside or outside the inflatable body 1. In the embodiment shown in FIG. 1-6, the pay-off and take-up device 5 is disposed outside the inflatable body and inside the base container 4, and the base container 4 may be connected to the inflatable body 1.

[0029] In the embodiment shown in FIG. 1-6, the gas charging device 6 is disposed inside the base container 4. The gas charging device 6 is communicable with the inflatable body 1 and used to charge the inflatable body 1 with gas. Specifically speaking, it charges the inflatable body 1 with gas when the inflatable body 1 is spread, and stops charging or slowly charges the inflatable body 1 with gas when the inflatable body 1 is retracted. In concrete implementation, the gas charging device 6 may adopt a charging fan, a gas pump or compressed gas, and the gas charging device 6 may also be built in the inflatable body or placed on another position.

[0030] As shown in FIG. 1, when the pay-off and take-up device 5 pays off the wire 3 while the gas charging device 6 is charging the inflatable body 1 with gas, the inflatable body 1 will be spread to form the needed shape. In FIG. 5, the gas charging device 6 stops charging the inflatable body 1 or slowly charges the inflatable body 1 with gas and meanwhile the pay-off and take-up device 5 takes up the wire 3, and through the wire 3 it pulls and tightens the wire positioning component 2 connected to the inner wall of the inflatable body, thereby retracting the inflatable body 1. The shape of fully retracted inflatable body 1 is shown in FIG. 4. Now the deflated and retracted inflatable body 1 is received into the base container 4. The base container 4 serves as a container receiving deflated and retracted inflatable body 1. Its shape and material are not limited and may be designed according to the shape and material of the inflatable body.

[0031] Please refer to FIG. 1 again. In order that the inflatable body 1 can realize timed automatic inflation and spreading or deflation and retraction, a time switch circuit board 9 may be added. It is connected to the gas charging device 6 and the pay-off and take-up device 5. The product also comprises a battery pack 7, which is connected to the time switch circuit board 9. All of the foregoing components may be placed in the base container 4. A power adapter 8 may also be connected to the battery pack 7 to charge the latter.

[0032] It should be noted that the present invention may be set in a mode of manual or automatic inflation and has no limitation to the shape and material of the inflatable body and the inflatable body may adopt different materials or shapes according to different demands. In an embodiment of the present invention, a luminous component is installed in the inflatable body. Besides, the present invention also has no limitation to the gas, which fills the inside of the inflatable body. The gas may be air or others.

[0033] The present invention provides an automatic retractable inflatable product. It realizes automatic retraction and tightening by providing a wire positioning component inside the inflatable body and passing a wire through the hollow annular elements of the wire positioning component so that the wire can be paid off or taken up through the pay-off and take-up device. This approach not only accelerates the deflation and retraction of the inflatable body but also reduces the volume of the inflatable body after deflation. The present invention also adopts the design of a base container to enable timely reception of the inflatable body after retraction, and introduces a time switch circuit board to realize timed spreading or retraction of the inflatable body, significantly improving usability and portability and making it convenient for protection, transport and storage.

[0034] The wires described in the foregoing embodiments may adopt various shapes and materials. There may be one or multiple wires subject to the actual structure.

[0035] Above the preferred embodiments of the present invention are illustrated by referring to accompanying drawings. Those skilled in the art may realize the present invention by various modified solutions without departing from the scope and spirit of the present invention. For example, the features partially presented or described in an embodiment may be used in another embodiment to get another embodiment. The above are preferred embodiments of the present invention and do not limit the range of rights of the present invention. All the equivalent changes made by applying the content of the description and accompanying drawings of the present invention are in the range of rights of the present invention.
