[Embodiment] Fig. 1 is a perspective view showing the entire carpet mat according to an embodiment of the present invention, Fig. 2 is a cutaway perspective view of the molding, and Fig. 3 shows the state in which the molding shown in Fig. 2 is attached to the side periphery of the carpet mat. FIG. The molding 2 is a long belt-shaped molded body made of soft plastic or rubber, and is preferably manufactured by extrusion molding. Specifically, a pair of opposing horizontal strips 2c and 2a are provided, and the pair of horizontal strips 2c and 2a are connected by a strip-shaped connecting portion 2b. A band-shaped protruding portion 2d is formed above the band-shaped connecting portion 2b and extending beyond one of the horizontal band-shaped portions 2c.

On the other hand, the sheet 3 made of fibers and the backing material 6
First, a carpet material of the same size is manufactured by laminating and integrating the carpet materials, and this carpet material is punched and cut using a cutting blade into a planar shape as shown in FIG. 1, for example.

As shown in FIG.
, 2a and the side edge surface of the carpet mat (
(cut surface) is covered with a band-shaped connecting portion 2b. One horizontal strip 2c is sewn and fixed on the surface of the side periphery of the carpet mat (the surface of the fiber sheet 3) using sewing thread 4A, and the other horizontal strip 2c is sewn and fixed on the back surface of the side periphery (the surface of the lining material 6). The portion 2a is sewn and fixed with sewing thread 4B. In this state, the side periphery of the carpet mat is bordered by the molding 2, and the height of the band-like protrusion 2d is higher than the height of the outermost surface of the fiber sheet 3.

FIGS. 4 and 5 show the molding guide used to sew such a molding onto a carpet mat.
This will be explained with reference to. The molding guide 7 is formed with an upper guide part 10, a side guide part 20, and a lower guide part 9, and a guide part 15 is provided between the upper guide part 10 and the lower guide part 9. Then, the side peripheral edges of the carpet mat are sandwiched between the guide parts 15, the attachment part 8 is fixed in a fixed position, and the carpet mat is slid and guided. Further, the other horizontal strip portion 2a is housed in the lower guide portion 9 having a substantially rectangular parallelepiped shape, and the strip connecting portion 2 is housed in the side guide portion 20.
Accommodates b. Furthermore, the upper guide part 10 accommodates one of the horizontal strips 2c and the strip-shaped protruding part 2d, but in this case, if the upper guide part 10 has a substantially rectangular parallelepiped shape as in the past, one of the horizontal strips Although it is possible to accommodate the section 2c, it is not possible to accommodate and guide the band-like protruding section 2d. Therefore, an expansion space 10a having a substantially triangular cross section is previously formed as the upper portion of the upper guide portion 10, and the band-shaped protrusion 2d is accommodated within this expansion space 10a.

In this manner, the side peripheral edge of the carpet mat and the molding 2 are simultaneously guided by the molding guide 7 and positioned relative to each other. Then, a sewing machine such as a thread sewing machine or a high-frequency sewing machine is installed near the mall guide 7.
The pair of horizontal strips 2c, 2a are sewn into the carpet mat as described above while the side peripheral edge of the carpet mat is continuously fitted between the pair of horizontal strips 2c, 2a.

The fiber sheet 3 may be made of either natural fiber or synthetic fiber, and may be a needle punch carpet, a tufted carpet, or the like. The fiber sheet 3 may be a woven fabric sheet made by knitting fibers, a sheet formed by flocking single fibers onto a backing material, or a sheet formed by bonding a large number of single fibers with a resin. It's okay. As the backing material 6, a sheet made of natural rubber, synthetic rubber, or soft plastic (vinyl chloride-vinyl acetate-ethylene copolymer, etc.) can be exemplified. Note that in the carpet mat of the present invention, the backing material 6 is not necessarily required.

[0020] Methods for laminating and integrating the fiber sheet 3 and the backing material 6 include a method of pasting them together with an adhesive, and a method of melting and solidifying plastic to fuse them together. Alternatively, a woven sheet or a non-woven sheet is prepared, these sheets and an unvulcanized rubber sheet are laminated, and this is pressurized and heated to vulcanize the unvulcanized rubber sheet and at the same time convert the rubber sheet into a woven sheet or a non-woven sheet. It can also be glued to the sheet. The molding may be made of either rubber or soft plastic, but it is especially economical to extrude soft vinyl chloride.

According to this embodiment, since the band-like protruding portion 2d of the molding 2 forms a peripheral wall surrounding the surface of the carpet mat, when the carpet mat is placed indoors and used, the surface of the carpet mat is prevents dirt, dust, dirt, etc. from spilling indoors. Also, when you take your carpet mat outside to clean it, make sure to remove dirt and dirt from the surface of the mat.
Dust, dirt, etc. are less likely to spill into the room. In particular, since the belt-like protrusion 2d is higher than the surface of the fiber sheet 3, the above effect is particularly large.

Furthermore, when manufacturing the carpet mat of this embodiment, the molding 2 can be continuously attached to the periphery of the carpet mat side using the molding guide 7, so the productivity itself at the time of molding installation is improved. is no different from the carpet mat shown in FIG. 7(b). Therefore, since it can be produced at the same cost and with the same labor as conventional products, it has no disadvantages from a production standpoint and is advantageous.

[0023] Regarding this point, the present inventor has experimented by complicating the shape of the edging molding and increasing the thickness of the periphery of the molding, but in these cases it was difficult to sew the molding with a sewing machine. It was found to be difficult and the four corners of the carpet mat were distorted after sewing. In the molding 2 of this embodiment, such sewing problems do not occur.

Further, according to the molding guide 7 used in this embodiment, the upper guide portion 10 has an expansion space 1 having a substantially triangular cross section.
Since the extension space 10a is provided, the band-like protrusion 2d can be easily accommodated in this expanded space 10a. In this example, the space between the pair of horizontal strips 2c and 2a is slightly expanded to accommodate a larger carpet mat.

FIGS. 6(a), 6(b), and 6(c) are front views showing a molding guide that can be suitably used when sewing the molding according to the present invention to the outer peripheral edge of a carpet mat. Components with the same functions as those of the molding guide in FIG. 4 are given the same reference numerals, and their explanations will be omitted. In the molding guide 11 shown in FIG. 6(a), an expanded space 12a having a rectangular shape with a slightly rounded cross section is formed in the upper guide portion 12, and a strip-like protruding portion of the molding is formed in this expanded space 12a. accommodate.

In the molding guide 13 shown in FIG. 6(b), an expanded space 14a having a substantially right triangular cross section is formed in the upper guide portion 14, and the strip-like protrusion of the molding is accommodated in this expanded space 14a. In the examples shown in FIGS. 6(a) and 6(b), the upper guide portions 12, 14 are relatively straight without being bent much.
contained within.

In the molding guide 16 shown in FIG. 6(c), the upper guide portion 17 is provided with an expansion space 17a having a substantially semicircular cross-sectional shape. When the strip-like protruding portion of the molding is accommodated in the upper guide portion 17, it is accommodated in a bent form along the shape of the inner wall surface of the expansion space 17a.

[0028]

Effects of the Invention According to the present invention, since the strip-like protruding portion of the molding forms a peripheral wall surrounding the surface of the carpet mat, when the carpet mat is placed indoors and used, the surface of the carpet mat can be easily Dirt, dust, garbage, etc. are less likely to spill into the room. Also, when taking the carpet mat outdoors to clean it, remove dirt, dust, and dirt from the mat surface.
It prevents trash from spilling into the room.

Furthermore, since one horizontal strip of the molding is fixed to the surface of the carpet mat and the other horizontal strip is fixed to the back surface of the carpet mat, the periphery of the carpet mat is located between the pair of horizontal strips. The molding can be attached to a carpet mat by simply fixing each horizontal strip to the front or back surface of the carpet mat. In particular, it is possible to accommodate the molding in the molding guide and guide the molding while continuously attaching it to the carpet mat. Therefore, the productivity itself when installing the molding is no different from that of conventional carpet mats, and it can be produced at the same cost and with the same labor as conventional products, so it is advantageous from a production standpoint as well.

Furthermore, according to the molding guide of the present invention, an expansion space is provided in the upper guide portion, and the strip-shaped protruding portion of the molding is accommodated in this expanded space, so that the strip-shaped protruding portion can be easily accommodated within the molding guide. and can be guided smoothly.
