1. Field of the Invention
The present invention relates to a colorful air cushion structure that is interiorly provided with color films so as to greatly enhance a colorful decorative effect thereof.
2. Description of the Prior Arts
In general, air cushions which are made of thermoplastic material, such as polyurethane, are widely used on the fillings of sport equipments, for example, the insoles of sport shoes or kneepads and the like, are applied for the shock-absorbing purpose thereof, thus achieving the prevention of sports injury.
Taiwan Patent Publication No. 313549, entitled “Manufacturing Method of Air Sac”, discloses that a conventional air cushion is made of thermoplastic material and has the property of transparency, unfortunately, such an air cushion doesn't have the property of changing three-dimensional color, hence it is difficult to draw people's attention by the color appearance.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a colorful air cushion structure, the inner top and bottom surfaces of an air chamber of which are laminated with color films so as to create a three-dimensional effect and show the variation of color components for making the air cushion eye appealing, when the light penetrates the wall thickness of the air cushion.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The main shell 10 is provided with a top surface 11 and a side surface 12 extending downwardly from the periphery of the top surface 11. The sub-shell 100 includes a bottom 13 formed symmetrically relative to the top surface 11, and the side surface 12 of the main shell 10 is tightly connected to the periphery of the sub-shell 100, so as to define an air chamber 14 between the main shell 10 and the sub-shell 100, thus forming the basic structure of the air cushion 1 of the present invention. The air chamber 14 can be filled with gel, fluid, foaming material, or pressurized air.
At specific positions of the top surface 11 relative to the bottom 13 are formed a plurality of concaves 15 that are connected to each other, so as to improve the structural strength of the air cushion 1.
The present invention is characterized as follows:
In the step of forming the main shell 10, the opposite side of the top surface 11 is laminated with a color film 20, and in the step of forming the sub-shell 100, the opposite side of the bottom 13 is laminated with a color film 30 as well so that the inner top and bottom surfaces of the air chamber 14 are laminated with color films 20 and 30 after the air cushion 1 is finished, thus forming the background color of the top surface 11 and the bottom 13 of the air cushion 1. The side surface 12 of the air cushion 1 is formed with a transparent area, and the color films 20 and 30 are attached to the inner surface of the concaves 15, creating a three-dimensional effect. By such arrangements, when the light penetrates the wall thickness of the air cushion 1 and the transparent area of the side surface 12, the air cushion 1 looked extremely beautiful against the color films 20 and 30, thus creating a three-dimensional effect and showing the variation of color components. Such a technical innovation substantially improves the visual interest, making the air cushion eye appealing. For example, the air cushion 1 is provided with black films 20 and 30 so as to define a semi-transparent or opaque area on the top surface 11, the bottom 13 and the concaves 15 of the air cushion 1, and plus the transparent area of the side surface 12, it can create a three-dimensional and colorful decorative effect.
The color film 20 or 30 can be a pattern film, a laser film, or an electroplating film, as long as it can create a three-dimensional and colorful decorative effect.
To sum up, the advantages of the present invention are listed as follows:
1. Having various changeable colors: because the colors of the air cushion of the present invention depend on the color films 20 and 30, any desired color can be formed onto the air cushion so as to show a superior visual effect, thereby enhancing the additional value of the air cushion. Moreover, due to the color films 20 and 30 are disposed in the air chamber 14, hence a color fading question resulted from friction will be avoidable.
2. Reducing the production cost: in the manufacturing process, because the color films 20 and 30 are disposed on the inner surfaces of the main shell 10 and the sub-shell 100 in an automatized manner, thus allowing the mass production so as to diminish the production cost.
3. Non-limiting the manufacturing shape of the air cushion: due to the shape of the air cushion of the present invention is formed based on the shapes of the mold cavity and the mold base, the random curvature and structural variation can both be obtained.
4. Merely increasing a little weight: the air cushion of the present invention is only additionally provided with the color films therein, thus merely increasing a little weight of it.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
