DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acupressure cushion using a flocked vinyl chloride sheet for a cushion body and having projections, valves and gussets attached thereto at a high frequency.

[0002]

2. Description of the Related Art Application No. 4-58961, filed on Jul. 8, 1992, was devised by Taneaki Fukami, the same person as the present applicant, and is now summarized. Then, it is an air cushion with a gusset, an air inlet, and a projection attached to the body of a cushion made of vinyl chloride. This is the same as when using conventional cotton, polyester, etc., without the collapse of the shape and the deterioration of elasticity, the comfort peculiar to the air pressure, and by attaching a gusset, it has two air chambers and controls the thickness of the cushion Had the effect of adjusting.
In addition, there is an effect that the fatigue of the muscles of the projections is reduced and blood circulation is improved. However, since the body of the cushion is made of ordinary vinyl chloride, there is a so-called PVC-like feel of vinyl chloride peculiar to vinyl chloride. To avoid this, it was necessary to attach a cover using lace or cotton. Therefore, installing the cover in addition to the cushion of the main body is about twice as expensive, and at the same time, when using an airplane or Shinkansen, the cushion and the cover are required.
Consumers wrote that they were heavy and troublesome when carrying them.

[0003]

SUMMARY OF THE INVENTION The consumer's voice has been humbly accepted, and the development of an air cushion with a projection that can be used without attaching a cover has been promoted. First, in order to eliminate the feeling of vinyl chloride, which is peculiar to vinyl chloride, a so-called PVC-like feel, we considered using flocked vinyl chloride as the material vinyl chloride. However, the flocked vinyl chloride is processed with a pile of about 0.2 to 0.5 mm obtained by finely cutting chemical fibers such as nylon on the surface of ordinary vinyl chloride. It has been found that it is impossible to thermally weld the formed protrusions directly with high frequency because chemical fibers such as nylon and vinyl chloride resin are different materials. Therefore, as a result of repeated research and trial production of a method of joining two different materials, we invented a new technique of joining projections to a flocking vinyl chloride sheet.

[0004]

Means for Solving the Problems Now, the structure will be described. (A) A protrusion 1 having a protrusion upper portion 2 and a protrusion base portion 3 made of vinyl chloride resin is thermally welded to a normal vinyl chloride sheet at a high frequency. Then, manufacture a plurality of vinyl chloride sheets with protrusions. (B) According to the shape of the cushion, a flocked vinyl chloride upper sheet 5 and a flocked vinyl chloride lower sheet 6 are manufactured. (C) A sheet having a plurality of circular holes formed on the upper sheet 5 of the flocking vinyl chloride sheet in accordance with the projection base 3 of the vinyl chloride sheet with projections, and the projections of the vinyl chloride sheet with projections are formed thereon. insert. (D) The outside of a plurality of holes formed in the upper sheet 5 of the flocking vinyl chloride, as shown by hatched portions in FIG.
A doughnut-shaped high frequency heat welding is performed to form an adhesive portion 7 between the flocking vinyl chloride upper sheet 5 and the vinyl chloride sheet 4, and indirectly fabricating a flocking vinyl chloride upper sheet with projections. (E) A valve 8 for inflow and outflow of air is heat-welded to the lower sheet 6 of flocking PVC at a high frequency to produce a lower sheet of flocking PVC with a valve. (F) The gusset 9 made of a vinyl chloride sheet is heat-welded at high frequency to the upper sheet of flocked vinyl chloride with projections and the lower sheet of flocked vinyl chloride with a valve. And heat welding.

[0005]

[Function] The flocked vinyl chloride sheet is flocked with a pile of synthetic fiber such as nylon, but the back side is a normal vinyl chloride sheet. As a result of the welding, the protrusions could be adhered to the flocking vinyl chloride sheet in an indirect manner.

【Example】

(A) The projection upper part 2 and the projection base part 3 are made of vinyl chloride resin.
The projection 1 having the following is manufactured. The protrusion upper part 2 can be made into a solid body and a hollow body. However, if the material is manufactured with the same hardness, the solid body becomes slightly harder and heavier. The hollow-shaped thing uses air pressure similarly to a cushion main body, and becomes an air cushion which has a double air structure. Therefore, it is possible to obtain a light and soft feeling peculiar to the air pressure. In addition,
A protrusion having a magnetic material can also be used. (B) A plurality of circular sheets, each of which has a radius of 0.5 to 1 cm longer than the circle of the protrusion base 3, are manufactured from a normal vinyl chloride sheet 4 which has not been subjected to flocking. The shape of this sheet is
Although a square, an ellipse, and the like can be used, it is reasonable to match the shape of the projection. (C) The protrusion base 3 is heat-welded to the circular sheet at a high frequency,
Manufacture multiple vinyl chloride sheets with protrusions. At the time of heat welding, the circle at the base of the protrusion slightly widens. (D) According to the shape of the cushion, a flocked vinyl chloride upper sheet 5 and a flocked vinyl chloride lower sheet 6 are manufactured. (E) A sheet in which a plurality of circular holes are formed on the upper sheet 5 of the flocking vinyl chloride sheet in accordance with the projection base 3 of the vinyl chloride sheet with projections, and the projections of the vinyl chloride sheet with projections are formed thereon. insert. (F) Flocking process The outside of a plurality of holes formed in the upper sheet 5 of vinyl chloride is heat-welded with a high frequency in a donut shape with a width of 2 to 3 mm as shown by a hatched portion shown in FIG. The bonding portion 7 between the vinyl upper sheet 5 and the vinyl chloride sheet 4 is formed, and indirectly, a flocking vinyl chloride upper sheet with projections is manufactured. The inside of the dotted line in FIG. 3 is a part of the vinyl chloride sheet 4, which is below the upper sheet 5 of flocking vinyl chloride and is not visible. (G) A valve 8 for air inflow and outflow is thermally welded to the lower sheet 6 of the flocking PVC at a high frequency to produce a lower sheet of the flocking PVC with a valve. Valve 8
May be used two or one. (H) The gusset 9 of the vinyl chloride sheet is heat-welded to the upper sheet of flocking vinyl chloride with projections and the lower sheet of flocking vinyl chloride with valves at high frequency, and further,
The peripheral portions of both sheets are also thermally welded at a high frequency. This creates an air cushion with two air chambers. When the valve 7 is attached to each chamber, the pressure of each air chamber can be independently adjusted by the amount of air to be injected. When one valve is used, an air passage is opened in the gusset 9 and both chambers are shared. (I) The shape and size of the cushion, the number of projections and the place to attach them can be freely manufactured according to the purpose of use, but FIGS. 4, 6, 7, 8, 9, and 10 show examples. It is.

[0007]

According to the present invention, it is possible to use the apparatus without attaching a cotton or lace cover, so that the price is reduced. At the same time, the material did not have a PVC-like feel, and it was possible to obtain a luxurious feel of flocking. In addition, when using vehicles such as airplanes and Shinkansen, it was possible to meet the demands of consumers, such as being lightly portable and eliminating troublesomeness. In addition, the technique of bonding the projections to the flocking vinyl chloride sheet of the present invention enables the projections to be bonded to various types of air cushions conventionally manufactured by various companies, thereby increasing the added value of the product. Is now available. That is, in addition to the support of the human body by the soft feeling peculiar to the air pressure that the conventional air cushion has, there is an acupressure effect such as improving blood circulation of the protrusion and relaxing stiffness. further,
The protrusions improve the air permeability of the cushion, and disperse the body pressure at which the protrusions come into contact with the human body. Therefore, there is little fatigue even when used for a long time, and there are synergistic effects such as prevention of back pain.
