Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe wipe separate mat which can be attached to and detached from a mat base for removing mud and dust on shoes of pedestrians by laying it at the entrance and exit of an entrance.

[0002]

2. Description of the Related Art Conventionally, a shoe-wiping mat has been laid at the entrance and exit of entrances to prevent dirt and dust adhering to shoes from being brought into the room.

In recent years, rental shoe wiping mats have become widespread, and mats used by each user are regularly collected, washed, and then subjected to an oil impregnation treatment to enhance dust adsorption, regenerated, and delivered again to each user. Things are to be done.

By the way, in the shoe-wiping mat, a mat base made of a rubber material is integrally formed on the bottom so as not to move when the person entering or leaving the room walks. For this reason, the shoe-wiping mat is divided into a mat body and a mat base, and only the mat body, which is easily polluted, is transported and washed. In such a shoe-wiping mat having a divided structure, a frame-shaped projecting edge is formed on the peripheral edge of the mat base, and the mat body is fitted in the central recessed space formed by the projecting edge. . However, if the mat body is simply fitted into the recessed space of the mat base, when the person entering or leaving the room walks, the mat body is easily displaced from the mat base or the end of the mat body is easily turned up. Therefore, the mating body and mat base are normally provided with a detachable locking mechanism on the contact surface between the mat body and the mat base to prevent the mat from turning over or coming off.

As a conventional shoe-wiping mat of this type, for example, the one shown in FIGS. 3 and 4 is known.

FIG. 3 is an exploded perspective view showing a conventional shoe-wiping mat, and FIG. 4 is a sectional view taken along the line AA of FIG.

In the figure, the mat main body 1 is formed in a rectangular shape as a whole, and is accommodated in a recessed space 2b formed by providing a projecting edge 2a on the peripheral edge of a mat base 2 arranged below the mat main body 1. ing. The mat body 1 and the mat base 2 are attached to the mat side adhesive cloth 3 attached to the four corners of the back surface of the mat body 1, and the mat side adhesive cloth 3 facing the mat cloth 3 to the four corners of the bottom surface of the recessed space 2b of the mat base 2. The base side adhesive cloth 4 is detachably attached by a pair of adhesive cloths called "velcro tape" or the like.

The mat body 1 is fixedly formed by tufting pile yarns 1b into a mat base fabric 1a and implanting them, applying latex such as NBR (butadiene-acrylonitrile copolymer) and drying to form a backing layer 1c. Has been done. The mat base 2 is formed by using oil resistant rubber such as NBR.

[0009]

The conventional shoe wipe separate mat is constructed as described above, and the latex is applied to the mat base cloth 1a by applying a tension parallel to the mat surface while keeping it flat. I am doing it. For this reason, the residual stress may fluctuate due to external force during use or during cleaning, and temperature changes during heating and cooling, resulting in dimensional shrinkage, and a gap is created between the mat base 2 and the projecting edge 2a, resulting in appearance quality. Sometimes caused a decrease.

Further, since only the latex is applied, the holding force of the shape of the mat base cloth 1a is weak, and the mat base cloth 1 is attached to the end surface of the mat body 1 during use or cleaning.
The yarn at the edge of the a may be loosened and protruded to the outside, which significantly impaired the appearance. Further, since the mat base cloth 1a has only a small amount of shape-retaining force after being coated with latex, the entire mat body 1 may curl inward due to drying after washing. Therefore, when it is attached to the mat base 2, it is necessary to perform an operation of stretching it to a flat surface, and even after it is stored in the mat base 2, there is a risk that the edges will rise and the user will get stuck when passing.

Therefore, an object of the present invention is to provide a shoe wipe separate mat which has good dimensional stability, can maintain a flat state, and does not loosen the threads of the mat base cloth during use or washing. .

[0012]

According to a first aspect of the present invention, in a shoe wipe separate mat, pile yarns are tufted into a mat base cloth and implanted, and a backing member made of a rubber material is placed on the back surface of the mat base cloth. After that, it was heat-vulcanized and bonded under vacuum suction.

According to a second aspect of the present invention, in the shoe-cleaning separate mat, pile yarns are tufted into the mat base cloth and implanted, and a backing member made of a rubber material is placed on the back surface of the mat base cloth. The adhesive cloth is heat-vulcanized and adhered under vacuum suction while the adhesive cloth is pressed and held at an appropriate position on the back surface of the backing member.

[0014]

According to the first aspect of the present invention, pile yarn is planted in the mat base cloth, the backing member is placed on the back surface of the mat base cloth, and vulcanized and adhered under vacuum suction without applying tension in the plane direction. Since it can be lined, there is almost no residual stress, and therefore, dimensional shrinkage due to external force during use or washing and temperature change is small. Also, since the backing material can be made thick,
The planar shape can be maintained, and the mat as a whole can be prevented from curling inward due to drying of the mat base cloth after washing. Further, as compared with the case of backing by applying latex, the backing is firmly backed by a thick backing member, so that the thread of the edge portion of the mat base cloth does not loosen and protrudes to the outside.

According to a second aspect of the present invention, a backing member is placed on the back surface of the mat base cloth, and an adhesive cloth is placed at an appropriate position on the back surface of the backing member, and both are vulcanized and bonded simultaneously. Therefore, the adhesive cloth can be easily attached without taking any additional means.

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 shoe wipe separate mat according to an embodiment of the present invention.

In the figure, the mat main body 1 is formed in a rectangular shape as a whole and is accommodated in a recessed space 2b of a mat base 2 made of an oil resistant rubber material such as NBR as in the conventional example. The mat body 1 is a mat attached to the mat-side adhesive cloth 3 attached to the four corners of the back surface and a mat 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. The base side adhesive cloth 4 is attached to the mat base 2 in a detachable manner by being locked to each other. 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 comprises a mat base fabric 1a made of woven or non-woven fabric such as general cotton fiber, acrylic fiber, nylon fiber, etc., made of cotton fiber, acrylic fiber, nylon fiber, etc., and tufted with pile yarn 1b. Backing sheet 1d made of oil-resistant rubber material such as NBR
Is formed by backing and joining. The backing sheet 1d which serves as a backing member for the pile yarn 1b has a plate thickness of about 0.5.
Uses a mm rubber plate. The pile yarn 1b has
After the mat body 1 is manufactured, an oil impregnation treatment is performed to enhance the adsorption of mud, sand, dust, etc. Therefore, the mat base 2 and the backing sheet 1d of the mat body 1 are made of NBR having excellent oil resistance. is doing.

Next, the lining of the shoe wipe separate mat of this embodiment will be described.

The mat base cloth 1a of the mat body 1 in which the roots of pile yarns 1b are implanted is housed in a vacuum heating furnace, the back side is set upward, and vacuum suction is carried out in the direction of the white arrow in the figure. Heat at a predetermined temperature for a predetermined time. The vacuum degree at this time is 60 mmHg or less, and the heating temperature of about 150 degrees is 10 to 15 degrees.
Heat for minutes. The heating temperature is equal to or higher than the melting temperature of the backing sheet 1d, and the mat base cloth 1a and the pile yarn 1 are heated.
The melting temperature or the softening temperature of b is set to be equal to or lower than the melting or softening temperature, and the setting may be appropriately changed depending on the rubber material of the backing sheet 1d, the mat base fabric 1a, and the pile yarn 1b.

First, the mat base fabric 1a of the mat body 1 is placed on a mounting 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. Set to suction state. Then, when heating is performed under vacuum in this manner, the backing sheet 1d is strongly sucked and pressed against the back surface of the mat base fabric 1a while holding the pile yarn 1b. Then, it is softened and melted by heating, the melted portion of the boundary layer permeates between the textures of the mat base fabric 1a, and is taken out from the vacuum heating furnace and cooled and solidified. And is firmly bonded to the mat base fabric 1a. Further, when heated, the vulcanizing agent in the backing sheet 1d chemically bonds with molecules in the rubber material and crosslinks into a network structure, improving elasticity and tensile strength, and reducing temperature changes in elasticity.

Since the backing sheet 1d has a slightly uneven surface due to the root portion of the pile yarn 1b, friction resistance with the bottom surface of the recessed space 2b of the mat base 2 is increased as in the conventional case. It acts as a lateral shift prevention inside.

As described above, in the shoe wipe separate mat of the above-mentioned embodiment, the pile yarn 1b is tufted into the mat base cloth 1a, and the mat base cloth 1a is embedded in the back cloth as a backing member made of a rubber material. After the sheet 1d is placed, it is heat-vulcanized and bonded under vacuum suction.

Therefore, according to the above-mentioned embodiment, the pile yarn 1b is planted in the mat base cloth 1a, the backing sheet 1d is placed on the back surface of the mat base cloth 1a, and vacuum suction is performed without applying tension in the plane direction. Since the backing can be performed only by heat-vulcanizing adhesion to the mat body 1, there is almost no residual stress in the mat body 1 as a whole, and therefore, dimensional shrinkage due to external force during use or washing and temperature change is small. Therefore, when the mat body 1 is housed in the recessed space 2b of the mat base 2, it is possible to prevent a gap from being generated at the edge of the mat body 1 and improve the appearance quality of the entire mat body 1.

Further, since the backing portion can be made thicker than in the case of lining by applying latex, the rigidity of the entire mat body 1 can be increased and the planar shape can be maintained, and the mat base cloth 1a after washing can be dried to dry mat. It is possible to prevent the entire main body 1 from curling inward. As a result, it is not necessary to perform a special operation to stretch the mat base 2 in a flat state, and it is possible to avoid the risk of tripping over when the edge rises after being stored in the mat base 2.

Further, as compared with the case of backing by applying latex, the backing portion has a larger wall thickness and is firmly backed, so that the thread at the edge of the mat base cloth 1b does not loosen and sticks out to the outside. It is possible to prevent deterioration of appearance quality.

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

In the figure, the mat side adhesive cloth 3 is attached to an appropriate place on the back surface of the backing sheet 1d of the mat body 1 of the above-mentioned embodiment, and the mat base cloth 3a made of woven cloth such as cotton fiber is A loop locking piece 3b in which a fiber such as cotton fiber is looped is implanted. The mat-side adhesive cloth 3 forms a pair of adhesive cloths together with the base-side adhesive cloths 4 attached to the four corners of the mat base 2, and the base-side adhesive cloth 4 is formed.
The mat body 1 is detachably attached to the mat base 2 by engaging with.

The mat-side adhesive cloth 3 is prepared by placing the backing sheet 1d of the mat body 1 on the mat base cloth 1a in which the pile yarns 1b are implanted, and then appropriately arranging the upper surface or back surface of the backing sheet 1d. The backing sheet 1d is placed at a place, and is pressed or sucked from above to be heat-vulcanized and adhered under vacuum suction to join the backing sheet 1d at the same time.

In this bonding, the backing sheet 1d of the mat body 1 is melted by heating and penetrates into the mat base cloth 3a and the loop locking piece 3b of the mat side adhesive cloth 3 to firmly bond and bond. Backing sheet 1d without special measures such as adhesive bonding with agents or sewing with sewing machines
Can be performed at the same time as the joining, the joining work is facilitated, and the cost is reduced.

By the way, the backing sheet 1d of the above embodiment
Although NBR is used, the present invention is not limited to this, and other rubber materials may be used. However, since the pile yarn 1b is subjected to oil impregnation treatment in order to enhance the effect of adsorbing mud, sand, dust, etc., NBR having excellent oil resistance is optimal. Also, the backing sheet 1d
A predetermined amount of vinyl chloride resin may be mixed in this case. In this case, the backing sheet 1d, the mat base cloth 1a, and the pile yarn 1b are used.
