Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The idea was to inflate the valve by injecting air into the valve, shrink it by evacuating the air, lay it under the bedding mat, The present invention relates to an airbag structure for moving a body by the inflation force of an airbag.

[0002]

[Prior art]

 As a conventional technique of this kind, a triangular air bag made of a vinyl chloride resin material is used to fill and exhaust air with an electric pump in a valve provided in the air bag. BACKGROUND ART There is known an air bag in which a mat placed on the air bag is moved to raise or lower a user on the mat.

[0003] As another known air bag technology, the air bag is laid under a mat, and the air bag is divided into two parts. Beds that automatically turn over are known.

[0004]

[Problems to be solved by the invention]

 However, in the case of the above-mentioned conventional technology, a triangular air bag is placed under a bedding mat, air is sealed in the air bag, and then excessive pressing force is applied to the inclined surface which is a load surface. Problems remain, such as the incline of the pressurized part and the incline of the slope, such as strong cushioning.

[0005] As described above, when the seat is inclined beneath the seat surface of the chair and the seat surface is inclined by using air pressure sealed in an air bag, the inclined surface, which is the pressurized surface, is stable because the pressure is not constantly changed. The problem remains that a seat cannot be secured.

[0006] Next, in another prior art, an air bag divided into two parts laid under a mat for automatic turning over is a rectangular shape, the width of which is divided into two parts in the longitudinal direction, and each air bag is divided into two parts. Since the air bag is inflated by alternately filling half of the valve with air, the pressurization of the inclined surface is unstable, and the user turns over while being exposed to an unstable and unnatural awkward inclined surface. The task of having to do it remains. That is, there is a disadvantage that a uniform pressing force does not always act on the inclined surface. In particular, the larger the slope, the more unstable.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned drawbacks, this invention is a bag-shaped closed body made of a triangular soft vinyl chloride resin, as shown in FIGS. The air is sealed and exhausted.

[0008] The air bag gradually inflates due to the air sealed in the triangular air bag 2, and the respective surfaces expand into a spherical shape so that the flat surface does not disappear. Each end 4a of the connecting member 4 made of a band-shaped cloth material is joined to the wall surface 3 so that the side surface does not expand beyond a predetermined length due to the sealing of air. The suspension 2e is formed by welding elongated vinyl chloride resin at equal intervals.

In addition, three sides other than both side surfaces of the airbag 2 are reinforced by suspending them 2e at equal intervals along the inner wall so that the three sides do not expand into a spherical shape due to sealing of air.

Next, other second and third embodiments described in FIGS. 4 to 8 are shown. Two airbags 2 ′ made of a soft vinyl chloride resin and made of a bag-like closed body, and made of an inflatable body and having a rectangular shape and a triangular shape, are integrated without any overlap. A valve 1 is provided on one of the side surfaces of each of the two air bags 2 'so as to be exposed to the outside.

Each of the airbags 2 ′ has a flat and rectangular appearance when the first airbag 2 a and the second airbag 2 b are exhausted without air from the valve 1, or the first airbag 2 ′ By operating the electric air compressor A in the bag 2a and filling air from the valve 1, a first inclined surface 2c is formed.

Further, by extracting air from the first airbag and filling the second airbag 2b with air, a second inclined surface 2d is formed. In this way, mutually opposite inclined surfaces, that is, inclined surfaces in two directions, leftward and rightward, can be freely reproduced.

That is, the load surface 5 ′ of each of the first inclined surface 2 c and the second inclined surface 2 d can secure a uniform internal air pressure.

Further, as described in the above embodiment, the sides 2e are provided with reinforcements 2e to reinforce the side surfaces and the respective sides so that the side surfaces and the respective sides are not deformed and expanded into a spherical shape due to excessive pressurization. The connecting body 4 'is joined to the wall surface 3'.

[0015]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail based on the illustrated embodiment. FIG. 1 is a perspective view of the airbag 2 of the present embodiment in an exhausted state. The airbag 2 has a triangular shape and is made of a soft vinyl chloride resin. This is a closed air bag 2.

Then, inside the triangular body of these airbags 2, both ends 4 a of a connecting body 4 made of a band-shaped thin cloth material are joined to inner wall surfaces 3 on both sides facing each other. Each of these fixing methods may be joined by using a locking tool.

As described above, the present embodiment employs one connecting body 4, but a plurality of connecting bodies 4 may be employed.

As described in FIG. 2, the air that passes through the hose A ′ by the operation of the electric air compressor A connected to the valve 1 is sealed in the valve 1 and is a triangular air bag 2. Is gradually expanded, and the excess air is sealed, so that both sides are prevented from being expanded by the connecting body 4 without being deformed into a spherical shape, and the internal pressure is secured uniformly.

In addition, suspensions 2e for reinforcement are provided at equal intervals along the inner wall surface of the bag body so that the three sides including the load surface 5 can evenly maintain the plane pressure.

In this manner, as shown in FIG. 3, after the air bag 2 having a triangular shape is filled with air, in this embodiment, the airbag 2 is placed under the end of the mat B, and the upper body of the user is placed on the bed surface. Can be automatically raised, and the load surface 5 can be re-sided with excessive pressure and variable pressure applied, and each of the three sides has no elasticity.

Next, a second embodiment will be described with reference to FIG. 4. As shown in FIG. 4, a rectangular bag and a triangular body are made of a soft material such as vinyl chloride resin. The shape of the triangular and rectangular body used to turn over on the bed is finished to the mat size of the rectangular bed, so that the first airbag 2a and the second airbag 2b are free-standing. Stacked and integrated. In this way, in the exhaust state, the appearance of one sheet material is finished.

Then, as described in FIG. 5, the first airbag 2a is not filled until the air is sealed from the electric air compressor A into the hose A ′ linked to the valve 1 on the side surface of the first airbag 2a having the above configuration. The first inclined surface 2c becomes the user's load surface 5 'when the airbag is gradually expanded and is manually stopped or automatically stopped with a predetermined expansion, but the second airbag 2b is a sheet-like upper surface of the first inclined surface 2c. Is laid.

Then, the user can automatically turn over on one side by the function of the first airbag 2a expanded into the triangular shape. Naturally, these first airbags 2a are generally used by being arranged under a mat or a mattress, and a combination of these is arbitrarily selected for practical use.

Next, air is charged from the electric air compressor A into the valve 1 on the side of the second airbag 2b which is integrally formed and inflated, so that the user performs the inclination opposite to the above-mentioned inclination. As described in the above, the air filled in the first air bag 2a is completely evacuated by the exhaust operation of the electric air compressor A, and the air filling of the second air bag 2b is started. .

After the air is filled, excessive pressing force from outside is applied to each of the inclined surfaces, so that each of the inclined surfaces causes the air inside the bag to generate an internal pressure on the side of the soft surface which is a spare for the side suspension 2e. The connecting body 4 ′ for preventing a state in which a load is applied and the respective inclined surfaces generate a cushion according to the curvature of the side surface, or a state in which a concave is formed and a constant internal air pressure cannot be maintained on the inclined surface is obtained. As shown in FIG. 7 in the third embodiment, the engagement is made with the inner wall surface 3 'of the side surface of the triangular body. These connecting bodies 4 'are engaged with a plurality of opposing side surfaces of the first and second airbags 2a and 2b.

Next, FIG. 8 shows a use example in which the automatic turnover air bag 2 ′ of the user in the double structure is mounted on the bed E. The state in which the air is sealed by operating the electric air compressor A to incline the mat B ′ and the bed C in which the user sleeps is inclined.

Next, each of the air bags 2, 2 'described above is completely welded by a welder method over the entire periphery of a triangular body made of a vinyl chloride resin material. The inclined surface is reinforced by providing a suspension 2e. When these airbags 2, 2 'are actually used in a state in which bedding is set, the airbags 2, 2' have no air permeability, so that the human body wicks away in a sweaty state. As a countermeasure against the accumulation of air on the airbags 2 and 2 ', the airbags 2 and 2' are laid on the load surfaces 5 and 5 'of the airbags 2 and 2' as a countermeasure. It is joined to the airbags 2 and 2 'to the extent that it does not slip off so that it can be detached. (Not shown)

In the air bag 2, 2 'in the above-described embodiment, the bag body is made of vinyl chloride or the like, and the air bag 2, 4' is bonded to or bonded to the opposing surfaces of the inner wall surfaces 3, 3 'on the side surfaces thereof. 4 and 4 ', the outer diameter of the airbags 2 and 2' will be described in detail in this embodiment by drawing them in a triangular shape, but as described in the claims, the airbags are specified in this shape. In order to make the load surfaces 5, 5 'uniform internal pressure even if they are polygons or irregular shapes, the connecting members 4, 4' facing each other inside the bag body are not specified even if they have an unspecified polymorph. That is natural.

[0029]

[Effect of the invention]

 The present invention is configured and operates as described above, and has the following excellent effects. The triangular shape 2 of the airbag is designed so that the surface receiving the load of the deformed body or the surface other than the side surface is reinforced by hanging it on the inner wall surface of the bag body so that the air pressure is evenly protected and both sides are not hung. The extension is connected to the extension part with a predetermined length to prevent expansion, so even if an irregular heavy pressure is applied to the load surface from outside, the shape may be deformed or the cushion may become unstable. It is possible to provide an airbag structure that can maintain a stable use surface without generation of air.

As described above, the air bag with a small cushioning property can safely move the object up / down and coordinate conversion by air pressure, and can always hold a stable surface, so that it can be used for many heavy-load product type applications. It can provide a possible airbag structure.
