Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cushion in which beads are enclosed.

[0002]

[Prior art]

 In general, various cushions in which beads made of plastic in the shape of a hollow sphere or a hollow cylinder are enclosed in a bag-shaped cushion cover have been developed. This is a plastic bead that is simply enclosed in a cushion cover, and a sofa-shaped one has a structure in which when you sit on it, the beads move and deform according to your body shape, supporting the body as a whole. . In addition, when applied to pillows, beads are packed tightly inside the cover, which has a restoring property, breathability and heat dissipation, and is effective for sleeping. However, when it is applied to a seat cushion, it is uncomfortable to sit because the beads swell if they are packed tightly inside the cover, and if the amount of enclosed beads is reduced, the beads will move to the corner side inside the cover and the seated part There was a problem that the beads were gone.

[0003]

[Problems to be solved by the device]

 The present invention eliminates the above-mentioned drawbacks, and a part of the beads moves and deforms according to the body shape, and the beads also remain in the part that hits the body, providing a stable and comfortable cushion. At the same time, the use of beads with excellent far-infrared radiation provides cushions that promote health.

[0004]

[Means for Solving the Problems]

 The cushion according to claim 1 of the present invention is a cushion in which beads are enclosed in a bag-shaped cushion cover, and the cushion cover is partially parted in a direction in which movement of the beads is hindered from a central side of the cushion cover toward an edge side of the cushion cover. It is characterized in that a plurality of linear sewn portions are formed at intervals by sewing, and the beads can be moved from the ends of the linear sewn portions.

When sitting on the cushion according to claim 1 of the present invention, the portion that comes into contact with the body is recessed, and while the body is moving, the linear sewn portion moves from the central portion of the cushion cover to the edge side. Since the beads are partially formed in the direction that hinders the movement of the beads, the beads move along the linear sewn portion and move outward only through the gap. For this reason, the beads can be deformed according to the shape of the body while remaining in the parts where the weight is most applied, and the weight can be supported evenly on the whole.

Further, the cushion according to claim 2 is characterized in that the beads are formed of plastic in which bamboo charcoal powder and seaweed charcoal powder are mixed in a total amount of 5 to 30% by weight. This bamboo charcoal powder and seaweed charcoal powder have a large specific surface area and high radiation performance of far infrared rays, so the cushion that encloses them is warm when sitting, and in addition, the oscillation of stress waves, alpha waves, allergic waves, etc. It also has excellent health promotion effects.

When the bamboo charcoal powder and the seaweed charcoal powder are mixed, it is preferable that the beads are formed by a plastic mixed in a total amount of 5 to 30% by weight. If the amount of bamboo charcoal powder or seaweed charcoal powder added to this plastic is less than 5% by weight, the far-infrared radiation effect will be small, and if it is added in excess of 30% by weight, the strength of the beads will decrease, and The above range is desirable because it may be damaged.

[0008]

[Embodiment of device]

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 is a cushion for a seat, and a large number of beads 3 are enclosed in a bag-shaped cushion cover 2 formed of cloth and having a square shape in a plane as shown in FIG. The cushion cover 2 has V-shaped linear sewn portions 4 and 4 symmetrically formed on the upper and lower sides centering on the central portion S, and has gaps 5 and 5 at both left and right corners of a square. .

Further, along the V-shaped linear sewn portions 4 and 4, a plurality of linear sewn portions 4 are diagonally formed at intervals toward the corner edge side of the cushion cover 2. , Gaps 5 are formed between the ends of the respective linear stitched portions 4. A hollow spherical plastic bead 3 having openings 6 on both sides is enclosed in the cushion cover 2 as shown in FIG. 3 (A), and as shown in FIGS. A cushion 1 for a seat, which is inflated between 4 ..., is formed.

When the seat cushion 1 is laid on, for example, a seat 7 of an automobile and seated on the seat 7, the portion that comes into contact with the buttocks 8 is recessed as shown in FIG. 5, and the body moves during driving as shown in FIG. As described above, since the linear sewn portion 4 is partially formed in the direction from the central portion S of the cushion cover 2 to the edge portion so as to prevent the movement of the bead 3, the bead 3 extends along the linear sewn portion 4. , And moves outward from the gap 5 ... As shown by the arrow. Further, since the beads 3 are made of plastic and are formed into a hollow sphere, they are slippery, and even if they are deformed, they have a resilience due to elasticity, so as shown in FIG. The 3 remains deformed along the shape of the buttocks 8 and can support the weight evenly as a whole, so the body is stable and fatigue is reduced even when sitting for a long time.

FIG. 6 shows another embodiment of the present invention, in which a semicircular line is formed around a central portion S of a bag-shaped cushion cover 2 formed of cloth and having a square shape in a plane. The sewn portions 4 and 4 are formed symmetrically, and gaps 5 and 5 are provided between them. Further, a plurality of arcuate linear stitching portions 4 are formed on the outer sides of the circular stitching portions 4 and 4 arranged in a circular shape in concentric circles at intervals. Hollow spherical plastic beads 3 are enclosed.

Also in the seat cushion 1 having this structure, the arcuate linear stitching portions 4 are partially formed in a direction from the central portion S of the cushion cover 2 toward the edge portion so as to prevent movement of the beads 3. As a result, the beads 3 can move along the linear sewing portion 4 and move outward only from the gaps 5 ...

FIG. 7 shows another embodiment of the present invention when applied to a cushion 9 for a backrest. This is a rectangular bag-shaped cushion cover 2 formed of cloth, with partition sewing portions 10 provided laterally along the longitudinal direction thereof at predetermined intervals, and a plurality of tubular storages in an air mat shape. The parts 11 ... Are formed. Vertically sewn linear sewing portions 4 are provided at intervals from the central portion S of each of the tubular storage portions 11 ... toward both edge portions, and both ends and upper and lower partition sewing portions 10, 10 are provided. There are gaps 5 ... Beads 3 are enclosed in each of the cylindrical storage portions 11 of the cushion cover 2 to form a cushion 9 for a backrest.

This is because the linear sewn portions 4 are partially formed in a direction in which the beads 3 are prevented from moving in the lateral direction while the body is moving by standing on the backrest of the seat and putting the back on it. Therefore, the beads 3 can be moved along the linear sewing portion 4 and can be moved to both sides only from the gaps 5 ... For this reason, the beads 3 will be deformed along the shape of the back while remaining on the back contact area, and the whole body can be supported on average, so the body is stable and less fatigue.

In the above description, the beads 3 are formed of hollow spherical plastics as shown in FIG. 3 (A), but as shown in FIG. 3 (B), openings are provided at both ends. A hollow cylindrical plastic provided with 6 or a spherical or cylindrical plastic may be enclosed. As this plastic, a thermoplastic resin such as polyethylene, polypropylene, or polyvinyl is preferable because of its high elasticity and resilience.

The beads 3 are preferably made of a plastic mixed with a material having a high far infrared radiation such as a bamboo charcoal powder or a seaweed charcoal powder. In this case, bamboo charcoal powder and seaweed charcoal powder have a larger specific surface area than charcoal and coconut husk activated carbon, and have a high far infrared radiation performance, so the cushion formed with this is warm when sitting, and on top of that, Since it has oscillations of tres wave, alpha wave and allergic wave, it is possible to obtain a cushion excellent in health promotion effect.

Further, the cushion of the present invention can be widely applied to a cushion for a sofa, a cushion for a bed, as well as a cushion for a seat and a backrest of an automobile. Further, the shape of the cushion cover 2 is not limited to the quadrangular shape, but may be a circular shape, an elliptical shape, or a polygonal shape.

[0018]

[Effect of device]

 As described above, in the cushion according to claim 1 of the present invention, a part of the beads moves and is deformed into a shape along the body shape, and the beads also remain in the portion that contacts the body, so that the cushioning is stable and comfortable to sit on. Is good. Further, in the cushion according to the second aspect, the beads are molded from plastic mixed with bamboo charcoal powder or seaweed charcoal powder, so that far infrared radiation is excellent and health can be promoted.
