DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a vertical sectional view showing a locking portion of a shoe wipe separate mat according to an embodiment of the present invention.

In the figure, a mat body 1 which is a shoe-wiping separate mat is formed in a rectangular shape as a whole, and is accommodated in a recessed space 2b of a mat base 2 made of oil-resistant rubber such as NBR as in the conventional example. . And the mat body 1
Is a mat-side adhesive cloth 3 attached to the four corners of the back surface, and a mat-base adhesive cloth 4 is attached to the four corners of the bottom surface of the recessed space 2b of the mat base 2 so as to face the mat-side adhesive cloth 3. And are engaged with each other and are detachably attached to the mat base 2. The mat-side adhesive cloth 3 and the base-side adhesive cloth 4 used for attaching the mat body 1 and the mat base 2 are known adhesive cloths that constitute a pair of detachable locking mechanisms.

The mat body 1 is formed by tufting a pile yarn 1b made of cotton fiber, acrylic fiber, nylon fiber or the like on a base fabric 1a made of woven or non-woven fabric of general cotton fiber, acrylic fiber, nylon fiber or the like. Implantation, NBR
Latex is applied to the back side of the base fabric 1a of the mat body 1 and dried to form the backing layer 1c, which is fixedly formed. In this state, the latex penetrates between the textures of the base cloth 1a of the mat body 1 and the pile yarn 1b
Since the root of the above penetrates into the latex by penetrating the base fabric 1a, it has high bonding strength. The mat body 1
Since the pile yarn 1b is subjected to an oil impregnation treatment in order to enhance the adsorption of mud, sand, dust and the like after the production of the NBR, the mat base 2 and the backing layer 1c of the mat body 1 are excellent in oil resistance NBR. Are using.

The mat-side adhesive cloth 3 has a base cloth 3a made of nylon fiber or the like, and a loop locking piece 3b formed by looping fibers of nylon, polypropylene or the like is implanted, and the back surface is coated with polyurethane resin or the like to provide a backing layer 3c. And the base cloth 3a and the loop locking piece 3b are fixed to each other.

The joining sheet 6 made of rubber such as NBR is
It is interposed between the mat body 1 and the mat-side adhesive cloth 3, and is integrated with the back surface of the mat-side adhesive cloth 3 by being sewn along the outer peripheral edge portion thereof, and then, with the mat-side adhesive cloth 3. The mating body 1 is joined at appropriate positions at the four corners by heat-bonding the opposite surface. As the material of the joining sheet 6, it is preferable to use a synthetic rubber sheet joined to a cloth to be integrated, or a material in which the cloth is embedded in the synthetic rubber sheet. That is, when the mat-side adhesive cloth 3 is sewn by using the cloth, the synthetic rubber can be prevented from being torn even if a large external force is applied to the suture thread. However, the bonding sheet 6 for carrying out the present invention is
It is possible to use synthetic rubber, synthetic resin, cloth, net cloth and the like.

Next, a method of manufacturing the shoe wipe separate mat of this embodiment having the above-mentioned structure will be described.

First, the mat base fabric 1a of the mat body 1 is placed on a placing table such as a crosspiece of the opening surface of the work table in a decompressed state so that the mat base fabric 1a is the lower surface, and the surface of the mat body 1 on the pile yarn 1b side is placed. Apply suction. Then, the base cloth 3a of the mat side adhesive cloth 3
After the root of the loop locking piece 3b is planted in and the backing agent such as polyurethane resin is applied and then dried and solidified, the backing agent that has permeated between the textures of the base cloth 3a is solidified, and the base cloth 3a and the loop member are looped. The root of the stopper 3b is firmly bonded. When a polyurethane resin is used as the backing agent, isocyanate and polyester or polyether are mixed in an equivalence ratio to form a urethane bond to form an adhesive layer. At this time, the reaction is accelerated by heating at a relatively low temperature.

Next, after the mat side adhesive cloth 3 is formed by the backing layer 3c of the base cloth 3a and the loop locking pieces 3b as described above, the bonding sheet 6 is superposed on the back surface of the mat side adhesive cloth 3. , Sew the peripheral edge with a sewing machine. After the mat-side adhesive cloth 3 and the joining sheet 6 are sewn together, the mat-side adhesive cloth 3 is cut into a predetermined size.

Subsequently, the matte adhesive cloth 3 and the joining sheet 6
A sewn item is placed at appropriate positions on the four corners of the mat main body 1 with the joining sheet 6 side abutting, and a seal heater, a high-frequency welder, etc. in a state where the mat main body 1 is pressed and held from above or vacuumed and held in position. Is used to heat at a predetermined temperature for a predetermined time. The heating temperature at this time is equal to or higher than the temperature at which the backing layer 1c of the mat body 1 and / or the backing layer 3c of the mat-side adhesive cloth 3 made of NBR is melted, and the base fabric 1 of the mat body 1 is heated.
a, the pile yarn 1b, the base cloth 3a of the matte side adhesive cloth 3, and the loop locking piece 3b are set to a temperature not higher than the softening temperature. As a result, the mat body 1 and the bonding sheet 6 can be thermally bonded,
Through this, the mat-side adhesive cloth 3 is attached to the mat body 1. In the case of heat vulcanization adhesion, it is performed after a predetermined adhesive is applied.

FIG. 2 is a vertical cross-sectional view showing an engaging portion of a shoe wipe separate mat according to another embodiment of the present invention.

In the figure, a recess 1d for accommodating the bonding sheet 6 is formed in the backing layer 1c of the mat body 1, and the depth of the recess 1d is approximately the same as the thickness of the bonding sheet 6. Has been formed.

That is, according to this embodiment, the mat body 1
Since the joining sheet 6 that is interposed between the mat-side adhesive cloth 3 and the mat-side adhesive cloth 3 is housed in the recess 1d of the backing layer 1c of the mat body 1, the bottom surface of the backing layer 1c of the mat body 1 is It becomes flat as a whole. Therefore, even if the thickness of the bonding sheet 6 is large, an unnatural step is eliminated at the mat-side adhesive cloth 3 attachment portion, the appearance is improved, and a feeling of strangeness is given when walking on the mat body 1. There is no.

As described above, in the shoe wipe separate mat of each of the above-described embodiments, the pile thread 1b and the backing layer 1c are used as the base cloth 1
a mat body 1 fixed to a, a mat side adhesive cloth 3 attached to an appropriate place on the back surface of the mat body 1, and a mat side adhesive cloth 3 sewn on the back surface of the mat side adhesive cloth 3; The other surface is formed of a rubber-made bonding sheet 6 bonded to the back surface of the mat body 1 by heat bonding.

Further, in the method for manufacturing the shoe wipe separate mat of the above embodiment, the sewing step of sewing the mat side adhesive cloth 3 and the joining sheet 6 made of a rubber material, and the joining sheet 6
The joining step of joining the opposite surface of the mat side adhesive cloth 3 to an appropriate place on the back surface of the mat body 1 by heat bonding.

Therefore, according to the above-mentioned embodiment, the joining sheet 6 is sewn and integrated on the back surface of the mat side adhesive cloth 3 in which the loop adhesive cloth 3b is embedded in the base cloth 3a of the mat side adhesive cloth 3. After that, since it is bonded to an appropriate place on the back surface of the mat body 1 by thermal bonding, a bonding mark such as a seam does not appear on the front surface side of the mat body 1. Therefore, it is possible to prevent deterioration of the appearance quality of the mat body 1.

Further, since the joining sheet 6 made of a rubber material is firmly joined in a molten state by heat bonding, the mat side adhesive cloth 3 can be separated from the mat body 1 even if the mat body 1 is repeatedly washed. Absent.

By the way, the bonding sheet 6 of the above embodiment is
Although using NBR, when practicing the invention,
The present invention is not limited to this, and other rubber materials may be used. However, since the pile yarn 1b is subjected to the oil impregnation treatment in order to enhance the effect of adsorbing mud, sand, dust, etc., NBR having excellent oil resistance is preferable. In addition, the bonding sheet 6 includes
A predetermined amount of vinyl chloride resin may be mixed, and in this case, the bonding sheet 6 and the mat side adhesive cloth 3 are melted and bonded not only by sewn but also by thermal bonding, so that the bonding strength is improved.

That is, the bonding sheet 6 that is bonded to the back surface of the mat-side adhesive cloth 3 when carrying out the present invention and is bonded to the backing layer 1c of the mat body 1 together with the mat-side adhesive cloth 3 is Any material may be used as long as it is integrated by means such as suturing, bonding or fusing, and can be bonded to the backing layer 1c of the mat body 1 by means such as bonding or fusing. Therefore, it is desirable that it can be firmly integrated. For this purpose, it is possible to use only a rubber sheet or only a synthetic resin sheet. And, in particular, the rubber sheet can be integrated with the backing layer 1c.

Further, in the pair of adhesive cloths of the above-mentioned embodiment, the loop engaging piece 3b of the mat side adhesive cloth 3 is formed into a loop shape, and the engaging piece of the base side adhesive cloth 4 is formed into a hook shape. When carrying out, it is not limited to this and the locking piece of the mat-side adhesive cloth 3 may be hook-shaped and the locking piece of the base-side adhesive cloth 4 may be loop-shaped. In addition, the hook-shaped locking piece may have another known shape such as a mushroom shape.

The pair of adhesive cloths of the above embodiment are attached to the four corners of the mat body 1 and the mat base 2, but in the case of carrying out the present invention, this position and the number are limited. It goes without saying that it is not a thing. Particularly, in a specific manufacturing process, the backing layer 1c is melted,
Since it can be manufactured by placing the mat-side adhesive cloth 3 on the upper surface thereof, even if the position, the number, and the shape affect the component cost, the effect on the manufacturing cost is small.
