JP2000236991A - Portable folding cushion - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily store and carry a cushion by containing an open cell synthetic resin foaming body in an airtight air bag having air supply valve, and cutting or half-cutting a part of the foaming body depending on the usage. SOLUTION: An airtight air bag 1 is provided with an air supply valve 3, and an open cell synthetic resin foaming body 2 whose shape depends on the usage is housed in the air bag 1 to produce a portable cushion. The synthetic resin foaming body 2 is cut or half-cut (cut to half the thickness of the foaming body) depending on the usage so that it can be folded in half or quarter, etc. When carrying the portable cushion, open the air supply valve 3 to fold the cushion in quarter, and press the cushion to discharge air from the air bag 1, and then close the air supply valve 3. When using the cushion, opening the air supply valve 3 automatically expands the cushion by a restoring characteristic of the foaming body 2 in the air bag 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION The present invention has been devised so as to be easily foldable in order to sufficiently fulfill the purpose of a foldable portable zabuton. The object is achieved by cutting and partially cutting a part of the stored open-cell synthetic resin foam.

2. Description of the Related Art At present, there is no commercialization of a cellular phone cushion for a mobile phone. In addition, the synthetic resin foam has a characteristic elasticity that makes it difficult to make a fold, and it is difficult to make the synthetic resin foam small.

[Problems to be Solved by the Invention] To use for a mobile phone is to make it as small as possible when storing it. However, the elasticity of the foam is repulsive to make it small, and we will never cooperate. I will not. ADVANTAGE OF THE INVENTION This invention can carry out storage operation easily in the state which formed the fold from the beginning, and can achieve the objective of a mobile phone with the shrinkage property of a synthetic resin foam.

[Means for Solving the Problems] Due to the elasticity of the synthetic resin foam itself, it is difficult to fold it properly in a fold. Therefore, a part of the synthetic resin foam according to the use form is required. By cutting and half-cutting
That problem was solved and folding was made easier.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the folding portable zabuton according to the present invention is provided with an air-tight air bag 1, a supply / discharge valve 3, and an open-cell synthetic resin corresponding to a form at the time of use. The foam 2 is housed therein.

FIG. 1 is a perspective view showing an embodiment of the most basic foldable mobile phone pad according to the present invention. FIG. 2 shows cutting and half-cutting of a synthetic resin foam (half-cut means half of the thickness of the synthetic resin foam, which means that only half is cut.) FIG. 2 is a plan view and a cross-sectional view showing a half-cut. AB are cut in half. C ~
E cuts half the surface on the opposite side to AB. E to D are completely cut. FIG. 3 is a perspective view showing a state of being bent according to the half-cut of AB, and FIG. 4 is bent in accordance with the half-cut of CE to make four-fold of FIG.

[0007] When the operation flow of the folding type portable band Zabuton is traced, as shown in Fig. 1, the supply / discharge valve 3 is opened at the time of the portable band, and four times based on the operations of Figs. Fold it up. Further, the air in the air bag is discharged by pressing in the direction of the arrow in FIG. By closing the supply / discharge valve 3 after compression, the compressed state is maintained and the shape becomes easy to carry. In use, by opening the plug of the supply / discharge valve 3, the foam expands naturally without inserting air into the mouth due to the restoring force of the foam in the air bag.

[Effects of the Invention] A feature of the present invention is that a synthetic resin foam having high elasticity is made smaller and easier to collect, and an object of the present invention is to provide a method for producing the same. At present, there is no mobile phone that uses this method. Therefore, the effect can be expected more than enough, and the value of convenience is indispensable for the improvement of life in making the most of leisure in the future.
