Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a sheet that is attached to the floor surface of a building, vehicle, etc. to protect the floor and also to ensure the safety of people walking.

[Conventional technology]

Conventionally, this type of flooring sheet has a non-slip function by providing grooves 11, 11' with a gutter-like cross section in relatively thin sheets 10, 10' made of synthetic resin or vinyl, as shown in Figs. 4 and 5. It is made to have. That groove 1
1,11' generally have a width and depth of 2 to 3 mm,
The pattern is also monotonous and linear as shown in the figure.

[The problem that the idea aims to solve]

By the way, the grooves in the flooring sheet not only serve to prevent people from slipping when walking as mentioned above, but they also have to be designed to allow water to flow well when washing the floor. Since the floor is configured horizontally, the conventional floor covering sheet 10,
In sheets 10', the grooves 11 and 11' have small dimensions and the cross-sectional dimensions at all locations are the same, so water drains poorly after washing, and sheets 10 and 10'
Water is floating on the surface, and the anti-slip function is not working properly when walking. Moreover, the groove 11,
The anti-slip effect is large even if the direction of the grooves 11' is uniform and the direction perpendicular to the longitudinal direction of the grooves 11, 11' is large, and there is almost no anti-slip effect in other directions, especially in the direction parallel to the longitudinal direction. .

[Means to solve the problem]

This invention was made in order to solve the problems of the conventional technology as described above.
The chevron portions and the groove portions are provided alternately in parallel, and the chevron portions are arranged in a staggered manner on the surface of the sheet, forming wide chevron portions whose cross sections vary widely at predetermined intervals in the longitudinal direction every few chevron portions. Further, the groove portions adjacent to and parallel to the left and right sides of the chevron portion having the wide chevron portion and other chevron portions are bent in a zigzag shape along the wide chevron portion in the longitudinal direction, so that the diagonal wide groove portion is formed in the groove portion, and the other chevron portions are bent in a zigzag shape along the wide chevron portion in the longitudinal direction. A wide angled angled portion is formed in the angled portion.

[Effect]

In this invention, the planar shape of the many parallel grooves provided on the surface of the sheet is bent in a zigzag pattern, which allows the grooves to diversify in direction, creating an anti-slip function from all directions. This helps prevent slips when walking. Moreover, by bending in a zigzag shape, a diagonal wide groove is formed in the bent portion, so that more water remaining after washing can be stored. At least if the cross-sectional shape is larger than that of conventional grooves, water will be less likely to rise to the sheet surface due to capillary action. Moreover, since water easily flows in the longitudinal direction of the groove 2, water drains easily when washing with water. In addition, wide chevron portions whose cross-sectional shapes are changed to wide at predetermined intervals in the longitudinal direction of the mountain are formed in every few chevron portions, and other chevron portions parallel to the chevron portion having this wide chevron portion are formed in the longitudinal direction of the chevron portions. Since the diagonal wide chevron portion is formed with a zigzag direction along the wide chevron portion, the impact resistance and abrasion resistance of the sheet are improved. Moreover, the wide chevron-shaped portion and the oblique wide chevron-shaped portion prevent large dirt and the like from entering the groove.

〔Example〕

An embodiment of this invention will be described with reference to the drawings.

In contrast to the chevron-shaped portion 1 of the sheet in FIGS. 1, 2, and 3, the groove portion 2, which is partially shaded in FIG. 1, has a practical depth and is approximately rectangular in cross section. The chevron portions 1 are formed with wide chevron portions 1b whose cross sections vary widely at predetermined intervals in the longitudinal direction of the general chevron portions 1a, and are arranged in a staggered manner on the surface of the sheet. has been done. Other chevron portions 1 adjacent to and parallel to the right and left of the chevron portion 1 having the wide chevron portion 1b are bent in a jagged shape in opposite directions to each other along the wide chevron portion 1b in the longitudinal direction of the general chevron portion 1a. A diagonal wide chevron-shaped portion 1c whose cross section is changed is formed.

Groove portions 2 adjacent to and parallel to the left and right sides of the chevron portion 1 having the wide chevron portion 1b are bent in a zigzag shape in opposite directions to each other along the wide chevron portion 1b in the longitudinal direction of the general groove portion 2a to change the cross section. A diagonal wide groove portion 2b or 2c is formed.

In the flooring sheet constructed in this way, the planar shape of the many parallel chevrons 1 and grooves 2 is bent in a zigzag shape, so the directionality of the grooves is diversified, and it has an anti-slip function from all directions. This causes slips to be prevented when walking. Moreover, since the groove portion 2 is bent in a zigzag shape and the oblique wide groove portion 2b or 2c is formed at the bent portion,
When the seat is washed with water, more residual water can be stored in the diagonal wide groove portions 2b or 2c than in the past, thereby reducing the amount of water coming out onto the surface of the seat and preventing slips when walking. Also, the water is in the groove 2
It flows freely in the longitudinal direction and drains easily. Furthermore, since every third chevron portion 1 has a wide chevron portion 1b, and other chevron portions 1 adjacent to and parallel to this have a diagonal wide chevron portion 1c, the impact resistance and abrasion resistance of the sheet are improved. do. Furthermore, the wide chevron-shaped portion 1b and the oblique wide chevron-shaped portion 1c prevent large dirt and the like from entering the groove portion 2.

In addition, in the flooring sheet of the above embodiment, the parallel grooves 2 may be provided with interlocking grooves that intersect with each other. It is also good to change the depth of the groove 2 in order to change the cross-sectional shape. However, it is not preferable to partially change the depth within one groove 2 because it obstructs the flow of water, and it is better to change the depth over the entire length of each groove 2.

[Effect of idea]

As described above, in the flooring sheet of this invention, the parallel grooves provided on the surface are bent in a zigzag shape, and the bent portions have wide diagonal grooves, so that a large amount of residual water can be stored during washing, and the sheet surface This reduces the amount of water that comes out and prevents slips when walking. In addition, water flows freely in the longitudinal direction of the groove, so water drains easily. Further, since the parallel chevron portions have wide chevron portions or obliquely wide chevron portions having a large cross section, the impact resistance and abrasion resistance of the sheet are improved. Moreover, since the grooves and the chevrons are bent in a zigzag shape, the directions of the grooves and the chevrons are diversified, and slips in all directions can be prevented when walking.
