Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a wooden floor structure that has good slip resistance when walking with slippers or socks and has a beautiful appearance.

(Prior Art and Problems Thereof) In recent years, housing facilities have been improved for an aging society, and wooden floors have been widely used in terms of appearance, elasticity and other habitability. However, since the conventional wooden floor structure is coated on the surface, it is slippery, which is very dangerous for the elderly, such as the elderly, who have weak legs. Therefore, conventionally, so-called anti-slip floor materials have been proposed as described in JP-A-55-65667 and JP-A-55-97036. These conventional anti-slip floor materials are said to have unevenness on the surface by forming shallow concave grooves (4) in the vertical and horizontal directions on the surface, and the anti-slip property is imparted by this, but these are merely estimates. It was something that had little scientific basis.

Now, under such circumstances, a testing machine (device name OYPSM) for testing anti-slip properties that matches the actual situation recently
Was developed in the Ono Laboratory of Tokyo Institute of Technology. According to this tester, it is safe for both slippers and socks that the value obtained by dividing the maximum tensile load by the applied load (CSR) is 0.3 or more, preferably 0.4 or more.

Therefore, as a result of performing an anti-slip test on the case of wooden floor materials, the value of the slippery parquet floor with a smooth surface was 0.322, but the one with the grid-like grooves (4)
It was 0.262, which was unexpectedly slippery. It is presumed that this is because the contact area with the slipper was reduced due to the presence of the groove (4). The same thing can be said from the test results of the floorboard having fine irregularities formed on its surface by shot blasting.

(Object of the present invention) The present invention has been made in view of the above-mentioned conventional example, and an object of the present invention is to provide a highly effective anti-slip floor structure based on experiments.

(Means for Solving Problems) In order to achieve the above-mentioned object, the present invention: In a floor surface (1) where a person's traveling direction is almost constant, such as a corridor or a doorway, the floor surface (1) Are almost flush with the floor surface (2) adjacent to.

Plural projecting ridges (3), which are one-piece products carved from the wooden flooring material forming the floor surface (1), are provided so as to intersect with the traveling direction of the person. The height is 0.5 to 2.0 mm and the width is 5 to 15 mm.

The interval between the ridges (3) is 2 to 4 times the width of the ridges (3).

Is adopted as a technical means.

(Operation) In the floor structure (A) configured as described above, when a person walks on the floor surface (1), the ridges (3) are projected in a direction intersecting the traveling direction. In addition, the protrusions (3) bite into the soles of the slippers and socks to exert an anchor effect, and at the same time, the soles of the slippers and socks enter between the wide protrusions (3) and reach the floor surface (1). Contact, and as a result,
It can effectively stop the slippage of the soles of the feet.

(Embodiment) Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.

The material used for the floor material is a relatively thick plate, and a plurality of ridges (3) formed by, for example, shaving, are integrally projected on the surface of the material. The height (H), width (a), and spacing (b) of the ridges (3) are as shown in Table 1.

The floor material thus formed was subjected to an anti-slip test using slipper or socks with the above-mentioned anti-slip tester (device name O / Y / PSM), and the results are shown in Table 1.

Here, (a) is the width of the ridge (3), (b) is the interval, (H)
Is the height.

From the above results, as shown in Comparative Examples ~,
With conventional products, slippers were barely used when using slippers on commercially available parquet floors, and barely showed slipperiness, but in all other cases, they were 0.3 or less and very slippery.

On the other hand, in the case of the embodiment, the height (H) of the ridge (3) is 0.5 to
When the width (a) is set to 2.0 mm and the width (a) is set to 5 to 15 mm, and the interval (b) between the ridges (3) is set to 2 to 4 times the width of the ridges (3), the slip resistance of the slippers and socks is generally Shows a CSR of 0.3 or more, showing effective anti-slip properties. However, when using CSRO.3 as a standard, it is highly likely that this standard will not be satisfied if it deviates from the above range. In particular, Examples 3, 4, and 6 exhibit a CSR of 0.4 or more and exhibit excellent slip resistance. However, even if a similar ridge is provided as shown in Example 4 and Comparative Example 4, due to the directionality,
Since there is a difference of 0.15 or more in CSR, the ridge (3) needs to be orthogonal to the traveling direction.

Therefore, on a floor surface (1) where the entrance of a house such as an entrance, an entrance of a bathroom or a washroom, and a corridor where the traveling direction of a person is substantially constant, the floor surface (2) adjacent to the floor surface (1) is ) And the floor material is constructed so that the ridges (3) intersect (usually orthogonal) to the direction of travel of the person, and therefore the ridges (3) are adjacent to each other. It is said to be higher than the floor surface (2). When walking on the floor material constructed in this way, the ridges (3) project in a direction intersecting the traveling direction, so the ridges (3) bite into the soles of the slippers and socks. At the same time as exerting the anchor effect, the soles of the slippers and socks can enter between the wide ridges (3) and come into contact with the floor surface (1), and as a result, the slipping of the soles of the feet can be effectively stopped. It can be done.

In addition, since the ridge (3) is an integrated body that is carved out of the floor material, for example, it has a heavier weight than the ridge (3) made of rubber or the like, and is used for general household use. There is no sense of incongruity. Further, since the ridges (3) project from the floor surface (1), water easily flows even if the floor surface (1) gets wet, and particularly the surface of the ridges (3) is very easy to dry. In addition, dust can be easily removed along the protrusions (3), and cleaning is easy.

The ridge (3) is high and the smaller the width of the ridge, the deeper it digs into the sole of the foot, and the higher the anchor effect, the better the slip resistance. However, if the ridge is high and the width is narrow, it easily breaks during use. . Further, it is not preferable because it is likely to be chipped in production. This width varies depending on the type of wood used, but if it is 4 mm or more for hardwood that is normally used, it can withstand use for a considerable period of time, and it can be damaged or worn by using synthetic resin injection (so-called WPC). Can be prevented. Thus, considering the anti-slip properties, the production aspect, and the use aspect, the proper anti-slip range is the above range.

(Effect) As in the above, the present invention reduces the height of the ridge protruding from the floor to 0.
The width is 5 to 2.0 mm, the width is 5 to 15 mm, and the interval between the ridges is 2 to 4 times the width of the ridges, so slipperiness and socks in the direction crossing the ridges are non-slip. Indicates that all of them have a CSR of 0.3 or more, and that they show effective anti-slip properties. Since it is constructed so as to intersect with each other, the ridges bite into the soles of the slippers and socks to exert an anchor effect, and at the same time, the soles of the slippers and socks enter between the wide ridges and the floor surface. There is an advantage based on the scientific evidence that it can effectively stop the slippage of the sole of the foot as a result. Further, on the floor surface at the construction site, since the floor surface having the ridge is almost the same as the adjacent floor surface, the ridge protrudes from the floor surface. When installed in a direction that intersects with each other, it is easy for water to flow even if the floor surface is wet, and it is easy to dry,
Further, there is an advantage that dust can be easily removed and cleaning is easy. In addition, since the ridge is a one-piece machined from the flooring material, it is more profound than the one made with rubber etc. .
