Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an air cushion device used in an airplane or the like.

[0002]

[Prior art]

 Airplanes are one of the longest rides on travel. He is forced to sit in the cabin for several hours to several tens of hours, which is said to be unpleasant for the body. In particular, it has been reported that prolonged seating may cause swelling of the feet, impaired blood circulation, and consequently blood clots (an article in the Yomiuri Shimbun “Health Sukuea” dated April 8, 2000).

[0003]

[Problems to be solved by the invention]

 Therefore, in the above article, there is a proposal to move the foot about once an hour in order to reduce the burden on the foot caused by sitting for a long time. An object of the present invention is to provide an air cushion device which can be portable and compact, and which can be used for stepping. Furthermore, the present invention provides an air cushion device that can be used in addition to such stepping.

[0004]

[Means for Solving the Problems]

 The present invention relates to an air cushion device having an air cushion space therein and having an injection / discharge portion for injecting air into this space and discharging air therefrom. There is disclosed an air cushion device provided with one or more sealed air separation portions.

[0005] Further, the present invention provides an air cushion device having an air cushion space therein and having an injecting / discharging portion for injecting air into this space and discharging air therefrom. One or more sealed air separation portions are provided, and the length in the direction perpendicular to the central direction is set to be about the width connecting both feet when a person is sitting on a chair. A cushion device is disclosed.

[0006] The present invention further discloses an air cushion device in which the air separating portion has an elliptical or circular shape.

[0007]

[Embodiment of the invention]

 FIG. 1 shows an example of a rectangular air cushion device of the present invention. The air cushion device 1 is made of a synthetic resin such as vinyl, and is a bag body in which a peripheral portion 12 is tightly sealed by high-frequency heating, and is partially sealed along a center line 6 thereof. Air separation units 2, 3, and 4. The separation parts 2, 3, 4 cut and remove a portion of the cushion in a circular or elliptical shape along the center line 6, and along the perimeters 2A, 3A, 4A on the cut line after the cut. Both sides of the front and back sides of the paper are firmly sealed by high-frequency heating. The air cushion space portions 10 and 11 are portions existing on both sides of the separation portions 2, 3 and 4, and narrow internal passages 7 and 8 interposed between the separation portions 2, 3 and 4. (Instruction, but actually indicates the inside)). It should be noted that even a circular cut may be elliptical due to air injection, and the difference between a circular and an elliptical cut is not particularly distinguished as a shape.

The cap 5 is for injecting and discharging air, and injects air by a foot pump or human breathing, and discharges air after use. The width L of the air cushion device in the direction orthogonal to the center line 6 was set to a length such that a person could step on the aircraft while sitting on a chair.

An example of use is shown in FIG. FIG. 2 is a view from the side surface 13 of the arrow in FIG. Compared with the air cushion spaces 10 and 11 on both sides of the separation sections 2, 3, and 4, the vicinity of the center line 6 having three sealed separation sections 2, 3, and 4 has an air passage area and a height h of about 3 cm. small. As a result, in a state in which the air is inserted, as shown in FIG. 2, the space portions 10 and 11 are greatly expanded with the separation portion therebetween. Then, by placing the left and right feet on the bulge portion from the A and B directions, cushion stimulation is given to both feet. Pressing down the A side foot expands the B side, and conversely, pressing down the B side foot expands the A side. In this way, compared to foot bamboo made by cutting bamboo, which is commonly used, into half, it was possible to obtain footwear with better cushioning properties.

When not in use, the cap 5 is removed, the air is extracted, folded, and stored in the bag. Thus, a portable and compact air cushion for stepping was obtained.

When air is injected, the air can be injected into the spaces 11 and 10 at the same time. However, due to the influence of the separation parts 2, 3, 4, the air is hardly introduced into the space 10 away from the cap 5. is there. In this case, first, air is introduced into the space 11, the cap 5 is closed, and the space 11 is pressed, whereby air flows into the space 10, and then the cap 5 is opened again to open the space 11. Preferably, air is injected into the air.

In addition to stepping, it can also be used for back reclining. In addition, although three separating units are used, there are two or four examples. Furthermore, the shape of the cushion 1 is rectangular, but there are also examples such as circular and elliptical. In addition, although it was used for in-flight use, it can also be used for trains and car trips, and can also be used for home use.

[Effect of the invention]

 According to the present invention, an air cushion device for stepping can be provided. It can also be used for back reclining.
