DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference is made to FIG. 1. The inflatable device with air bag comprises at least one air bag 1, at least two first assembly portions 2 and at least two second assembly portions 3.
The air bag 1 is made of flexible materials. The air bag 1 has a main body 11, an air room 12 and an air-inlet opening 13. The main body 11 is formed by two flaked bodies 111 that are combined together. The edges of the two flaked bodies 111 are fastened to form a fastening portion 112 and the air room 12. The air room 12 in the main body 11 is separated from external environment. The air-inlet opening 13 is located on the surface of the main body 11, and the air-inlet opening 13 links the air room 12 with external environment. Air in the external environment can enters into the air room 12 via the air-inlet opening 13 to be filled in the main body 11. However, air in the external environment is blown into the air-inlet opening 13 by mouth or an air pump (not shown in the figure). Thereby, the quantity of air filled into the main body 11 determines the inflatable degree of the air bag 1. Due to the flexibility of air, the surface of the air bag is soft to provide the shock-releasing effect and the pressure-proof effect.
The first assembly portion 2 can be assembled with the second assembly portion 3. The first assembly portions 2 and the second assembly portions 3 are fastened on the fastening portion 112 of the air bag 1. The first assembly portion 2 and the second assembly portion 3 are symmetrically located at the edge of the air bag 1 so that the air bag 1 can be assembled with another air nag 1 to become an air bag 1 with larger dimension. For example, the two first assembly portions 2 are respectively located at the upper edge and the left edge of the air bag 1, and the two second assembly portions 3 are respectively located at the lower edge and the right edge of the air bag 1.
The air bag 1 is used for wrapping an object (such as cell phone, PDA, walkman, laptop or baggage). The first assembly portion 2 is assembled with the second assembly portion 3 so that the object is stably placed in the air bag and it can prevent the object from impacted or pressed. In the first embodiment, the air bag 1 is folded by half and the first assembly portion 2 is assembled with the second assembly portion 3. The first assembly portion 2 and the second assembly portion 3 can be designed with different types. For example, the first assembly portion 2 and the second assembly portion 3 are respectively designed as a Velcro hook surface 2A and a Velcro loop surface 2B (referring to FIG. 2). When the inflatable device with air bag wraps the object 4, the Velcro hook surface 2A located at the upper edge of the air bag 1 is assembled with the Velcro loop surface 2B located at the lower edge of the air bag 1. Alternatively, the Velcro hook surface 2A located at the left edge of the air bag 1 is assembled with the Velcro loop surface 2B located at the lower right of the air bag 1 for preventing the object 4 wrapped in the inflatable device with air bag from being impacted or pressed. Moreover, the first assembly portion 2 and the second assembly portion 3 can be designed as a first zipper 2B and a second zipper 3B (referring to FIG. 3). By utilizing the zipper head (not shown in the figure), the first zipper 2B is assembled with the second zipper 3B to achieve the same effect. Furthermore, the first assembly portion 2 and the second assembly portion 3 can be designed as a convex portion 2C and a concave trough 3C (referring to FIG. 4). The convex portion 2C is wedged with the concave trough 3C to achieve the same effect. However, the size of the air bag 1 can be changed according to the requirements. Reference is made to FIGS. 5 and 6. The air bag 1 can wrap the laptop or baggage with a larger dimension to prevent the object 4 from being impacted or pressed.
In the second embodiment, the inflatable device with air bag of the present invention uses two air bags 1 to wrap object. For example, two sides of the object 4 respectively have an air bag 1 (referring to FIG. 7). The first assembly portion 2 and the second assembly portion 3 of one of the two air bags 1 are respectively assembled with the first assembly portion 2 and the second assembly portion 3 of another air bag 1 to form an enclosed space and the object 4 is spaced in the enclosed space. The inflatable device with air bag wraps object 4 to prevent the object 4 from being impacted and achieve the waterproof effect and the moisture-proof effect. Furthermore, two air bags 1 are detachably assembled to form an air bag with larger dimension (referring to FIG. 8). That detachably assembled means the air bags 1 are enable to be disassembled. Next, the air bag 1 is folded by half to wrap the object 4. The first assembly portion 2 and the second assembly portion 3 can be Velcro, zipper, or pressed strips to achieve the same effect.
In the third embodiment, the inflatable device with air bag of the present invention uses four or more than four air bags 1 to wrap object. For example, the upper side, lower side, left side and left side of one air bag 1 are respectively assembled with one air bag 1 to form a larger air bag 1 (referring to FIGS. 9 and 10). Therefore, the inflatable device with air bag has four or more than four air bags to wrap object 4. The first assembly portion 2 and the second assembly portion 3 of one of the air bags 1 are respectively assembled with the second assembly portion 3 and the first assembly portion 2 of another air bag 1 so that the air bags 1 form an enclosed space to wrap the object to prevent the object 4 from being impacted and achieve the waterproof effect and the moisture-proof effect. The first assembly portion 2 and the second assembly portion 3 can be Velcro, zipper, or pressed strip to achieve the same effect.
