Abstract

PROBLEM TO BE SOLVED: To provide a beads cushion sofa having excellent shape keeping performance which fits the body of a seated person to support the person, and in which foam beads in a bag return to horizontal positions to restore a cushion form before the person is seated when the seated person leaves it. SOLUTION: A number of foam beads 2, 2'... are enclosed in a bag body 1, when a number of the foam beads 2, 2'... of a roughly similar volume to an inner volume of the bag body 1 are enclosed. A bottom surface 3 and a side surface 4 of the bag body comprise non-expansion material, and a mirror surface 5 comprises expansion material. An opening hole for charging/ discharging the foam beads 2, 2'... is provided in the bottom surface 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bead cushion sofa.

2. Description of the Related Art Conventionally, a large number of foam beads, each of which has a smaller volume than that of a bag, are sealed in a non-stretchable bag. There was something that fit and supported the sitting position.

[0003] In the case of the above, since the bag has no elasticity, an empty space in which the foam beads can move due to the load at the time of sitting is required. The foam beads that have moved in the direction of gravity try to return by gravity, but the foam beads that have moved in the horizontal direction are kept as they are without applying external force, they do not return to their original positions, and it is difficult to maintain a certain shape In addition, there has been a drawback that, when used for a long period of time, the swelling gradually expands in the horizontal direction, and the fit during sitting is impaired.

Therefore, sometimes the size of the bag is adjusted,
It was necessary to adjust the position of the foam beads.

[0005]

SUMMARY OF THE INVENTION When a seated person separates from a seated person, the body is fitted and supported in accordance with the seated person.
It is an object of the present invention to provide a bead cushion sofa which is excellent in keeping the foam beads in the bag naturally returning to the horizontal position and returning to the cushion shape before sitting.

[0006]

Means for Solving the Problems In a bag (1) in which a large number of expanded beads (2) (2 ')... Are enclosed, the internal volume of the bag (1) is substantially equal. Encloses a large number of foam beads (2) (2 ′)... To reduce the volume, and the bottom surface (3) and the side surface (4) of the bag body (1) are made of a non-stretchable material and have a mirror surface (5) is made of a stretchable material, and foam beads (2) (2 ') are provided on the bottom surface (3).
A bead cushion sofa having an opening / closing opening (6) for taking in and out of the bed.

[0007]

The bag (1) has a bottom surface (3) and a side surface (4) made of a non-stretchable material, and a mirror surface (5) made of a stretchable material, which is sealed in the bag (1). Since the amount of the firing beads is about the same as the inner volume of the bag (1), the movement of the firing beads when seated is limited to only above and below the mirror surface (5) made of an elastic material, It can be supported in a shape that fits the sitting posture.

When the load is removed away from the bead cushion sofa, the fired beads (2) (2 ')... Which have moved up and down are forced to return to the base of gravity and the mirror surface (5). Moves to the original flat surface position and restores to the shape without load.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which a bottom surface (3) and a side surface of a substantially cylindrical bag (1) are shown. The periphery (7) of the mirror surface (4) and the mirror surface (5) is made of a vinyl chloride sheet as a non-stretchable material, and the fiber itself has a stretchable spandex as a mirror surface stretchable material. .

The foam beads enclosed in the bag (1) are styrene foam granules having a particle size of 1 to 2 mm.
The firing rate is about 30 times, and as shown in FIG. 2, the bottom surface (3) has an opening and closing opening which can be opened and closed by a fastener (8), so that the amount of firing beads can be adjusted.

As shown in FIG. 3, when a person sits on the object of the present invention, since the bottom surface (3) and the side surface (4) are made of a non-stretchable material, the inside of the bead is formed on the side surface. (2)
Is disturbed by movement, and the firing beads (2) displaced by the seated body have a mirror surface (5) made of an elastic material.
Movement is limited only to the up and down direction of the firing beads (2)
Movement raises the mirror surface (5) to a shape that supports the shoulders and sides from the back of the body.

FIG. 4 and FIG. 5 show another embodiment of the present invention. As shown in FIG. 4, the foam beads (2) enclosed inside the bag (1) protrude from the seam of the bag (1). Inner bag (9) with double structure of bag (1) to prevent
The inner bag (9) also has a non-stretchable material on the bottom and side surfaces, like the outer bag (1), and a mirror-like stretchable material is used.

As shown in FIGS. 3 and 4, the bottom surface (4) (4 ') of the bag (1) and the inner bag (9) can be opened and closed by fasteners (8) (8'). In particular, a cover cloth (10) covering the fastener (8) is attached to the fastener (8) of the outer bag (1) in order to prevent the grounding surface from being scratched to the floor by the fastener. The other side, which is not joined, is fixed by a velvet type fastener (11).

[0014]

According to the present invention, the bag (combined with a stretchable material and a non-stretchable material) is compared with a conventional bead cushion in which a large number of foam beads are sealed in a bag made of a non-stretchable material. Many firing beads in 1) (2) (2 ')
····················································································································································· Movement of the firing beads (2) due to the load on the body is limited to the vertical direction of the mirror surface (5). The beads (2) and (2 ') ... are supported in a shape along the body over the back, buttocks, and thighs, so that even pressure is applied to the body and the body can be seated for a long time. There is no pain in the specific part, especially the buttocks.

When the seated person stands up and the load is removed, the firing beads (2) (2 ') moving on the mirror surface (5) are returned to the original horizontal position. Back to
Since the shape of the cushion body returns to the shape when the load was not applied, unlike a conventional bead cushion, the shape does not deform even after long use, and the size of the bag is adjusted. Also, there is no need to adjust the position of the firing beads, and the fit during sitting is not impaired.
