DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, mats laid between boards in the form of carpet have poor cushioning properties, are easy to slip, easily generate wrinkles in a direction perpendicular to the direction of rush, have poor heat retention, and are easily warped upward at outer peripheral edges and corners. There was a problem.

[0003]

DISCLOSURE OF THE INVENTION The present invention has a high cushioning property, is hard to slip, hardly generates wrinkles perpendicular to the direction of the rush, is excellent in heat retention, and has an outer peripheral edge or a corner (or a corner) which is upwardly bent. The purpose is to obtain a mat carpet that is not likely to be damaged.

[0004]

According to the present invention, a sponge sheet is superimposed on a lower surface of a mat, and an outer edge of the sponge sheet and an outer edge of the sponge sheet are sandwiched by an edge cloth. The cloth and the sandwiched mat and sponge sheet are sewn, the sponge sheet is compressed along the sewing line, the sponge sheet inside is swelled downward along the sewing line, and the slope from the compression section toward the swelling section is swelled. The rug according to the first aspect of the present invention, wherein the rug with a downward pulling force is a crest flower mat. The sponge sheet is constituted by the rug according to the first or the second aspect, wherein the sponge sheet is a synthetic resin porous flexible elastic sheet.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, when a mat 1 is laid on a floor plate 7, the sponge sheet 2 on the lower surface comes into contact with the floor plate 7, and the sponge sheet 2 on the lower surface of the outer peripheral edges 3 and 3 'is along the sewing line 5. Since it is compressed and reduced in thickness, it is laid on the floor plate 7 from the floor plate 7 via the space s.

The sponge sheet 5 inside the sewing line 5 bends and bulges in a normal state, and a tension (inward tension) in the direction of arrow a acts on the curved portion 8 so that the resultant moment b of the compression portion 6 is lowered. Since it works in the direction, the edges and corners of the mat 1 are always subjected to downward stress and do not warp upward.

[0007] Therefore, the outer peripheral edge 3 of the mat 1 adheres to the floor plate 7 through the space s, and the lower surface of the mat 1 contacts the floor plate 7 with the flexible and elastic sponge sheet 2, and the upper surface of the mat 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 on the floor plate 7.

Further, the floor plate 7 and the sponge sheet 2 have sufficient mutual frictional resistance and adhere to each other, and the sponge sheet 2 does not slip on the floor plate 7. In addition, the sponge sheet 2 is flexible but elastic and therefore has a good cushioning property and does not wrinkle in a direction perpendicular to the direction of the rush 9 of the mat 1.

The above-mentioned effect can be obtained even if a synthetic resin porous flexible elastic sheet is used in place of the sponge sheet 2.

[0010]

EXAMPLE A sponge sheet 2 having the same dimensions as a plane contour is superimposed on the lower surface of a pattern-free mat 1 or a crest flower mat 1 '. Mat 1 or 1 '
Of the sponge sheet 2 and the outer peripheral edge 3 'of the sponge sheet 2 are sandwiched by a double-folded edge cloth 4 along a longitudinal folding curve 4 ",
The folded upper and lower edge cloths 4 and the mat 1 and the sponge sheet 2 (or synthetic resin porous flexible elastic sheet, for example, urethane foam) sandwiched therebetween are stitched by sewing.

As shown in FIGS. 2 and 3, the sponge sheet 2 is compressed 6 along the sewing line 5 (a line along the outer periphery of the edge cloth 4) by the sewing stitch 4 '. The sponge sheet 2 inside the lever bulges 2 'downward and normally.

The tensile force in the obliquely downward direction along the arc-shaped lower surface curved portion 8 toward the compression portion 6 and the bulging portion 2 'is applied to the outer peripheral edge 3 and the compression portion 6 as shown by arrows a in FIGS. Attached to
Since a downward resultant moment b acts on the outer peripheral edge 3 and the compression portion 6, the outer peripheral edges 3, 3 'are always urged downward, thereby suppressing a force or habit of curving upward.

In the drawing, reference numeral 10 denotes a strip, 11 denotes a pattern of a crested flower mat, and 12 denotes a fold line of a mat 1 '.

[0014]

According to the present invention, as described above, a sponge sheet or a synthetic resin porous flexible elastic sheet is polymerized on the lower surface of the mat, and the outer peripheral edge is sandwiched between edge cloths to form a single carpet. Not only is it warm and in good contact with the floorboard, it does not slide and is not only highly secure, it is also durable, wrinkles in the direction perpendicular to the rush direction are not easily generated, and it is flat and stable without the possibility of the outer peripheral edge and corners warping upward. There is an effect that can be used on floorboards.
