Abstract

PROBLEM TO BE SOLVED: To obtain a straw mat carpet with cushioning effects and without curling upward at the outer peripheral edge and the corner part. SOLUTION: A sponge sheet 2 is laid over the lower face of a straw mat 1, then the outer peripheral edge 3 of the straw mat 1 and the outer peripheral edge 3' of the sponge sheet 2 are held with an edge cloth 4, and the upper part and the lower part 4, 4 of the edge cloth, the straw mat 1 and the sponge sheet 2 are stitched together 4'. Further, the sponge sheet 1 is compressed along the stitch line 5, and the lower part of the sponge sheet 1 inside the stitch line 5 is bulged downward so that a tension is applied obliquely downward from a compressed part 6 to a bulged part 2'.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carpet-like rug made of squid.

[0002]

2. Description of the Related Art Conventionally, a scabbard laid between carpets in a carpet shape has a poor cushioning property, is slippery, is easily wrinkled in a direction perpendicular to the direction of strawberries, is poor in heat retention and is easily warped upward at the outer peripheral edge and corners. There was a problem.

[0003]

DISCLOSURE OF THE INVENTION The present invention has a high cushioning property, is hard to slip, is unlikely to cause wrinkles at right angles to the direction of strawberries, is highly heat-retaining, and has an outer peripheral edge or a corner (or corner) that is upwardly curved. The purpose is to obtain a mosquito carpet that has no risk of being damaged.

[0004]

In order to achieve the above object, the present invention superimposes a sponge sheet on the lower surface of a scabbard, and sandwiches the outer peripheral edge of the squid and the outer peripheral edge of the sponge sheet with a hem cloth to form upper and lower edges. Sew the cloth and the sandwiched sword and sponge sheet, compress the sponge sheet along the stitching line, bulge the inside sponge sheet downward along the stitching line, and incline from the compression section to the swelling section. Rug provided with downward pulling force. Rug according to the above-mentioned first invention in which the mosquito is a moss flower. It is constituted by the rug according to the above-mentioned first or second invention, in which the sponge sheet is a synthetic resin porous flexible elastic sheet.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, when the scabbard 1 is laid on the floor plate 7, the sponge sheet 2 on the lower surface comes into contact with the floor plate 7, and the sponge sheet 2 is formed along the sewing line 5 on the lower surfaces of the outer peripheral edges 3 and 3 '. Since it is compressed 6 and has a reduced thickness, it is laid on the floor plate 7 from the floor plate 7 through the space s.

The sponge sheet 5 on the inner side of the sewing line 5 is curved and bulges in a normal state, and a tension in the direction of arrow a (pulling force toward the inside) acts on the curved portion 8 and the synthetic moment b of the compression portion 6 is lowered. Since it works in the opposite direction, the edges and corners of the scabbard 1 are always subjected to downward stress and do not warp upward.

Therefore, the outer peripheral edge 3 of the shell 1 sticks to the floor plate 7 through the space s, and the lower surface of the shell 1 is in contact with the floor plate 7 by the flexible and elastic sponge sheet 2 and the upper surface of the shell 1 By stepping on the air, the air in the sponge sheet 2 is released to the outside of the sheet 2, and the sheet 2 is adsorbed to the floor plate 7.

Further, the floor plate 7 and the sponge sheet 2 have sufficient mutual frictional resistance and are in close contact with each other, and the sponge sheet 2 does not slip on the floor plate 7. Further, since the sponge sheet 2 is flexible but has elasticity, it has a good cushioning property, and does not cause wrinkles in a direction (longitudinal direction) perpendicular to the direction of the strawberries 9 of the scorpion 1.

Even if a synthetic resin porous flexible elastic sheet is used in place of the sponge sheet 2, the above-mentioned effect is exhibited.

[0010]

Example: A sponge sheet 2 having the same planar contour is superposed on the lower surface of the unpatterned scabbard 1 or the crest flower scabbard 1 '. 1 or 1'bamboo
The outer peripheral edge 3 of the sponge sheet 2 and the outer peripheral edge 3'of the sponge sheet 2 are sandwiched by a hem cloth 4 which is double folded along a longitudinal folding curve 4 ",
The folded upper and lower edge cloths 4, and the scabbard 1 and the sponge sheet 2 (or the synthetic resin porous flexible elastic sheet such as urethane foam) sandwiched between the upper and lower edge cloths 4 are sewn with a sewing machine to form a stitch 4 '.

2 and 3, the sponge sheet 2 is compressed 6 along the sewing line 5 (line along the outer periphery of the edge cloth 4) by the sewing stitch 4 ', and along the sewing line 5 as shown in FIG. The sponge sheet 2 on the inner side of the lever bulges 2'to the normal state downward.

Along the arc-shaped lower curved portion 8 toward the compression portion 6 and the bulge portion 2 ', a downward pulling force is applied obliquely downward as shown by arrows a in FIGS. Is attached to
Since the downward composite moment b acts on the outer peripheral edge 3 and the compression portion 6, the outer peripheral edges 3 and 3'are always urged downward to suppress the force or habit of bending upward.

Reference numeral 10 in the drawing is a warp, 11 is a pattern of crested flower buds, and 12 is a folding line of the bud 1 '.

[0014]

As described above, according to the present invention, the sponge sheet or the synthetic resin porous flexible elastic sheet is polymerized on the lower surface of the cocoon as described above, and the outer peripheral edge is sandwiched by the edge cloth to form a single carpet. It is warm and adheres well to the floorboard, does not slide, and is not only highly fixed, but also wrinkle-free in the direction perpendicular to the direction of strawberries and highly durable, and the outer periphery and corners are flat and stable without the risk of warping upward. There is an effect that can be used on the floor board.
