Abstract

PROBLEM TO BE SOLVED: To provide a finger-pressure cushion wherein a protrusion made of polyvinyl chloride resin is efficiently bonded to a flocked polyvinyl choride sheet for a main body of the cushion with high frequency heat. SOLUTION: A protrusion comprising a protrusion base part and a protrusion upper part 1 made of polyvinyl chloride resin is manufactured, and a round hole to correspond to an inner circle of the protrusion base part is made in an upper sheet 4 of flocked polyvinyl chloride. The protrusion upper part is inserted into the round hole from the bottom, and the upper sheet 4 of flocked polyvinyl chloride and a connecting part 6 for the protrusion base part are bonded in the shape of a ring with high frequency heat. An air-intake and exhaust valve is bonded to a lower sheet of flocked polyvinyl chloride with high frequency heat. A gusset made of playvinyl chloride sheet is bonded to the upper sheet of flocked polyvinyl chloride with the protrusion and the lower sheet of flocked polyvinyl chloride with the valve with high frequency heat, and the peripheries of the both sheets are welded with high frequency heat.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acupressure cushion in which projections made of vinyl chloride resin are adhered to a flocked vinyl chloride sheet of a cushion body by high-frequency heat.

[0002]

2. Description of the Related Art The applicant of the present invention previously invented and commercialized an acupressure cushion in which projections made of vinyl chloride resin were bonded to a cushion body made of a normal vinyl chloride sheet by high-frequency heat. However, this has a so-called PVC-like feeling that the body of the cushion is a normal PVC sheet, and the peculiarity of vinyl chloride is netinecchi.
In order to avoid this, it was necessary to attach a race or a cover using cotton. Therefore, the price is high, and when using a vehicle, it is inconvenient to carry. Therefore,
We have researched acupressure cushions with protrusions that can be used without a cover. As a result, in order to eliminate the PVC-like feeling of a normal vinyl chloride sheet, a method of bonding the protrusions using a flocked vinyl chloride sheet as a material was invented, and this method was described in Japanese Patent Application No. 8-356545. Filed with the Patent Office. According to the present invention, one technique for bonding the protrusions of the vinyl chloride resin to the flocking vinyl chloride sheet was disclosed, and the original object was achieved. However, this technique previously required a manufacturing step of bonding the projections to a normal non-flocked vinyl chloride sheet. For this reason, there are disadvantages such as poor work efficiency, high labor cost and high material cost, and at the same time, the product becomes slightly heavy.

[0003]

Research and trial production for eliminating these drawbacks have been repeated. As a result, the surface of the flocked PVC sheet is flocked with a pile of synthetic fibers such as nylon, but the back side is a normal PVC sheet. Has invented a new technique for bonding the projections efficiently. Now, an embodiment thereof will be described below.

[0004]

【Example】

(A) A plurality of protrusions having a protrusion upper portion 1 and a protrusion base portion 2 made of vinyl chloride resin as shown in FIG. 1 are manufactured. The projection upper part 1 can be manufactured in a hollow shape or a hollow shape. The protrusion shown in FIG. 2 has a hollow shape.
Note that a projection having a magnetic material can be used as the projection. (B) As shown in FIG. 3, a plurality of circular holes 5 are formed in the upper sheet 4 of flocking vinyl chloride so as to match the circle 3 inside the projection base 2. (C) As shown in FIG. 4, the protrusion upper part 1 is inserted into the circular hole 5 from below, and the joining part 6 between the flocking-treated vinyl chloride upper sheet 4 and the protrusion base part 2 shown in the hatched part is formed into a ring-shaped high frequency. Adhere with heat. The dotted line indicates the outer circle portion of the projection base 2 and is an invisible portion. (D) As shown in FIG. 5, the projections are bonded to a plurality of locations on the top sheet 4 of flocking vinyl chloride by high-frequency heat in the same manner. (E) As shown in FIG. 6, an air inlet / outlet valve 8 is bonded to the lower sheet 7 of flocking vinyl chloride by high-frequency heat. (F) As shown in FIG. 7, a gusset 9 made of a vinyl chloride sheet is divided into an upper sheet 4 made of flocked vinyl chloride with projections and a lower sheet 7 made of flocked vinyl chloride with a valve.
And the peripheral portions of both sheets are bonded by high-frequency heat. Although the shape and size of the cushion main body and the arrangement of the projections differ depending on the purpose of use, FIGS. 8 to 12 show examples of these embodiments, in which various cushions including an air pillow can be manufactured.

[0005]

According to the present invention, the flocking vinyl chloride sheet and the projections of the vinyl chloride resin can be efficiently bonded. This has shortened the manufacturing process and saved labor and material costs, while at the same time reducing the weight of the product and improving the visual quality. Therefore, the feeling of vinyl chloride sheet sticky and PVC-like is eliminated, and at the same time, there is no need to attach a cover, the price is reduced, and when used in vehicles, the portability is light and convenient. In addition, according to the present invention, it is possible to efficiently and economically bond the protrusions of the vinyl chloride resin to various air cushions using a flocking vinyl chloride sheet which has been conventionally commercially available. Now you can add value. 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. Furthermore, since 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, there is little fatigue even when used for a long time, and a synergistic effect such as prevention of back pain can be obtained.
