Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mat base, and relates to a mat base that is designed so that even when a mat that has been cleaned and shrunk is attached, the shrunken state is not noticeable.

Mats placed at entrances to buildings are essential to prevent dirt from shoes from being carried indoors.

This mat is usually raised like a carpet, placed on a mat base made of synthetic rubber, synthetic resin, etc., and removably fixed with velvet fasteners or the like.

However, this mat is cleaned after a predetermined period of use, but the mat shrinks when cleaned.

On the other hand, the pine base is usually shaped like a quadrilateral and has upright protrusions surrounding its periphery, so that the mat that has been cleaned and shrunk will not shrink on the pine base. If the mat is placed again, the shrinkage will be noticeable at a glance due to the gaps created between the protrusions and the edge of the mat, which is unfavorable in terms of appearance.

A detailed analysis of the reason why such a contracted state is noticeable at a glance is as shown in FIG.

Fig. 1 is a partially enlarged sectional view illustrating a state in which a contracted mat is placed on a conventional mat base having upright protrusions. A protrusion 1a is formed in an upright position.

The material indicated by the reference numeral 2 is a mat, and this mat 2 has raised naps 2a on its upper surface.

In the state shown in FIG. 1, the mat 2 is cleaned and shrunk, and there is a gap 3 between the inner edge of the protrusion 1a and the edge of the mat 2.
This indicates a situation in which this occurs.

In such a state, the thickness of the mat 2 is visually recognized by the viewer as the thickness including up to the nap 2a, and the thickness of the mat 2 is the thickness including the raised ridges 1
It is recognized that there is a deep groove-shaped gap 3 between the inner edge of the mat 2 and the edge of the mat 2.

Further, the valley line portion 4 formed by the fusion of the inner base end of the protrusion 1a and the upper surface of the pine base 1 is recognized as a clear straight line, further enhancing the deep groove-like shape of the gap 3.

Now, if we connect the inner upper edge of the protrusion 1a and the lower end of the edge of the mat 2 by a straight line l, we can see that there is a gap between the inner edge of the protrusion 1a and the upper surface of the mat base 1, as shown in FIG. It can be seen that a right triangle is formed with the line l as the hypotenuse.

Therefore, if a slope including this hypotenuse is formed on the inside of the protrusion 1a, the cross-sectional area of the gap 3 will be less than half, making it impossible to feel the size of the gap, and this part becomes an inclined surface. The existence of the valley lines 4 is no longer recognized, and the viewer cannot visually recognize the existence of voids caused by shrinkage of the mat.

The present invention uses the above-mentioned principle and provides a mat base that can prevent the user from noticing the gap formed between the mat that has shrunk due to cleaning and the protrusions of the mat base. It is something.

The details of the present invention will be explained below along with embodiments shown in the drawings.

Figure 2 and subsequent figures are for explaining the details of the present invention. In the figure, the symbol 5 in its entirety is a mat 1 base, which is shaped into a quadrilateral flat plate made of resin, rubber or the like. A protrusion 6 is formed around the entire circumference.

As is clear from FIGS. 3 and below, the protrusion 6 has a semicylindrical shape that gently bulges upward with a predetermined width, and its upper surface is a gently arcuate surface.

The projecting rim 6 is shaped as a frame having a smooth curved surface over its entire circumferential surface.

The top of this protrusion 6 is located at the center of the protrusion, and its inner edge is fused with a recess 5a, which is a space for placing the mat surrounded by the protrusion 6 of the mat base 5. The size of the quadrilateral is smaller than the size of the placed pine 1- in its most contracted state after several cleanings.

When the mat 7 is placed on the mat base 5 shaped as described above, the edge of the mat 7 becomes a curved surface on the inner side of the top of the ridge 6 before shrinking, as shown in FIG. The edge of the mat 7 is located in the middle of the curved surface.

In this way, even if the edge of the mat 7 rides on the curved surface inside the top of the protrusion 6 and the raised ridges 7a are located slightly above the protrusion 6 as shown in cross section in FIG. Since the nap 7a is flexible, it will not get caught on the tips of shoes, causing the user to trip, or the mat will not be rolled up.

Also, after cleaning the mat 7 when it becomes dirty,
When placed on the mat base 5 in the most contracted state, the mat 7 will be in the state shown in FIG.
The edge of the mat base 5 is located at approximately the same position as the fused portion of the concave portion 5a and the inner circumferential edge of the protrusion 6, and overlaps the circumferential edge of the curved portion, so that the edge of the concave portion 5a cannot be seen.

In this way, even if the mat 7 shrinks and gradually retreats downward on the inner curved surface of the protrusion 6, as shown in FIG. 4 and FIG. There is only a continuous curved surface between the edge and the protrusion 6, and there is no valley line at the base end of the upright wall of the protrusion as shown in FIG. There are no grooves formed between the mat and the protrusions, and there is no shape that most clearly indicates that the mat has shrunk.

As is clear from the above description, according to the present invention, a semi-cylindrical protrusion 6 is formed surrounding the periphery of the pine base and gently curved upward with a predetermined width, and the circumferential surface of the protrusion 6 is Since the mat has a structure with a smooth curved surface over the entire surface, the edges of the mat are located on the gently curved surface forming the protrusions 6, so even if the mat shrinks to its most contractible state after several cleanings. The edge of the mat does not contract more than the inner edge of the protrusion 6, and the curved surface of the protrusion 6 always exists at the edge of the mat.

Therefore, unlike conventional mat bases with upright protrusions, there is no valley line at the inner base end of the protrusions, so there is no deep groove-like gap between the edge of the mat and the protrusions. ,
Rather, the protrusions 6 function as a decorative frame of a predetermined width, making it possible to provide an excellent mat base that does not cause shrinkage of the mat due to cleaning.
