Description

[Detailed description of the invention] The present invention maintains effective cushioning properties while
To provide a floor covering that has good anti-slip properties and is easy to clean.

BACKGROUND ART Synthetic resin floor mats with uneven surfaces to prevent slipping have been developed and are widely used. However, since such bedding has an uneven surface, it is difficult to remove the dirt stuck in the recesses using general-purpose cleaning tools such as motsupu or polisher, and it is difficult to remove the dirt stuck in the recesses with a vacuum cleaner or with a scrubbing brush. I had to go through troublesome cleaning such as washing it with etc. Furthermore, the cushioning properties were also unsatisfactory.

The present invention was developed to solve the above-mentioned problems, and it has a cushioning property that is effective on the entire surface of the floor without compromising its good anti-slip function, and it is also easy to clean. This relates to a useful bedding designed to

The bedding according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the present invention, FIG. 2 is an enlarged partial sectional view taken along the line -- in FIG.
FIG. 3 is an explanatory diagram of the usage state of the same embodiment, and as shown in the figure, the bedding of the present invention includes a core material layer 2 provided with a recess or hole, and a protrusion fitted into the recess or hole. 11 on the lower surface, and a surface layer 3 having elasticity laminated on the upper surface of the cushion layer.

In the bedding illustrated in FIGS. 1 and 2, the bedding core material 2 is configured with rectangular mesh-like holes, and each hole is provided with a convex portion on the lower surface of the cushion layer 1 having the same thickness as the core material 2. 11... are fitted together, and a surface layer 3 is bonded onto the cushion layer 1 via an adhesive (not shown).

In addition, if necessary to completely prevent falling off, the cushion layer 1 and the bedding core material 2 may be bonded or welded, or an appropriate backing material 4 may be attached as shown by the dashed line in FIG. Of course, they may be combined.

As the material for the cushion layer 1, for example, soft foams with good cushioning properties such as pasty vinyl chloride resin, urethane resin, butadiene resin, or similar sponge bodies are preferably used. The core material 2 may be a hard or semi-hard thick perforated sheet made of hard or semi-hard vinyl chloride resin or other synthetic resin, in which a large number of fitting holes are formed for the projections 11 on the lower surface of the cushion layer 1; Currently commercially available thick synthetic resin non-woven nets (for example, Takiron Co., Ltd., trade name: Trical Net) are suitably used. Incidentally, in the relative hardness difference between the cushion layer 1 and the core material 2, as long as the core material 2 is harder, it goes without saying that the material of the core material 2 itself may be softer. be. As the surface layer 3, for example, a relatively thin sheet or film made of stretchable soft or semi-hard vinyl chloride resin or other elastomer is preferably used.

When a load is applied to the surface of such a bedding while walking, as shown in FIG. Along with this, the surface layer 3 corresponding to the positions of the protrusions 11... on the lower surface of the cushion layer 1 also stretches and bends concavely, so that the protrusions 11... on the lower surface of the cushion layer 1 become recesses. In addition, the hard bedding core material 2 becomes a convex portion, and due to the presence of the cushion layer 1 on the upper surface of the bedding core material 2,
The cushion layer 1 on the upper surface of the bedding core material 2 is also slightly compressed, and the surface layer 3 also follows this, so that effective cushioning performance is achieved even in the portion corresponding to the upper surface of the bedding core material 2, and unevenness is reduced. A surface is formed, which provides a good anti-slip effect.

At this time, it is desirable that the thickness of the recessed portion of the cushion layer 1 corresponding to the upper surface portion of the bedding core material 2 is one-half or less of the thickness of the bedding core material 2.

Next, when the load is removed, the entire surface of the cushion layer 1 expands and returns to its original state, and at the same time, the surface layer 3 also shrinks to its original state and presents a smooth surface. In this way, the bedding of the present invention satisfies effective cushioning performance over the entire bedding, forms an uneven surface only when a load is applied, and exhibits a good anti-slip effect, and at other times. Since it has a smooth surface, it does not get clogged with dirt in the recesses like conventional bedding, and can be cleaned very easily without leaving any dirt behind, making it extremely hygienic. In this case, the diameter of the convex portion 11 on the lower surface of the cushion layer 1 is set to approximately 0.5 to
5 cm, and the distance between the protrusions 11 on the lower surface of the cushion layer 1 is set to approximately 0.2 to 5 cm, the cushioning performance can be maintained over the entire surface of the bedding, and the uneven surface formed can be It is possible to obtain a bedding that has hooks and has an even better anti-slip effect.

It goes without saying that the floor covering of the present invention as described above may include various embodiments other than those described above without departing from the scope of the claims for utility model registration. Figures 4 and 5 show another typical embodiment of the present invention, in which a sheet in which circular recesses are formed at random from the beginning is used as the bedding core material 2; A cushion layer 1 is formed to fill the storage recesses 21 and cover the upper surface of the bedding core material 2, and a similar surface layer 3 is bonded thereon via an adhesive (not shown). . It is clear that such a bedding also exhibits the same excellent effects as those of the above embodiments.

In the above embodiment, the protrusions 11 on the lower surface of the cushion layer 1 take the form of rectangular or circular shapes scattered vertically and horizontally or randomly, but the protrusions 11 on the lower surface of the cushion layer 1 are parallel to each other. Of course, it is possible to fill the holes or recesses of any shape in the corresponding core material layer 2 with the strip-shaped material or the material with other shapes.

As described above, the bedding of the present invention maintains effective cushioning performance over the entire surface of the bedding, has a good anti-slip effect, and can be cleaned extremely easily without leaving any dirt behind. It is extremely hygienic and practical.
