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 its problems) In recent years, housing equipment has been improved for an aging society, and its appearance has been matched, and wooden floors have been widely used from the viewpoint of elasticity, heat insulation and other habitability. There is. 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.

Under these circumstances, a testing machine (device name O ・ Y ・ PS) for testing anti-slip properties that matches the actual situation recently
M) 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 a wooden floor material, the slippery surface of the parquet floor was 0.322 in the case of slippers.
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 the 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 scientific experiments.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides: On a floor surface (1) of a place where the traveling direction of a person 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 (b) between the ridges (3) is set to 2 to 4 of the width of the ridges (3).
Appropriately combine the doubled one with 5 mm or more and less than twice the width of the ridge.

The technical means called; is adopted.

(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 ridges (3) bite into the soles of the slippers, socks, and the like to exert the anchor effect, and at the same time, the soles of the slippers and the socks enter between the wide ridges (3) and the floor surface (1). It is possible to effectively stop the slippage of the sole of the foot as a result.

(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) are integrally projected on the surface by cutting or other processing. The height (H), the width (a), and the intervals (b) and (c) of the ridges (3) are as shown in Table 1.

The floor material thus formed was subjected to a slip resistance test using the slip resistance tester (device name: O / Y / PSM) using slippers and socks, and the results are shown in Table 1.

From the above results, 0.322 is only when slippers are used on the commercially available parquet floor of Comparative Example-2, and barely shows a moderate slip resistance, but in all other cases,
It is less than 0.3 and very slippery.

In Comparative Example-1, the height (H) of the ridge (3) is 0.5 to 2.0 m.
m, the width (a) is 15 mm or less, and the interval (b) between the ridges (3) is 2 to 4 times the width of the ridges (3) and the slip resistance test against slippers and socks is performed. The result, CSR
It can be seen that the value is 0.3 or more and the slip resistance is excellent.

In the case of Examples 1 to 5, the height (H) of the ridge (3) is 0.5 to
2.0 mm, its width (a) is 15 mm or less, and the interval (b) between the ridges (3) is 2 to 4 times the width of the ridges (3) and 2
This is an example of a combination with a doubled amount or less, but slip resistance in slippers and socks still shows CSR of 0.3 or more, showing effective slip resistance. In particular, Example 5 exhibits a CSR of 0.4 or more and exhibits excellent slip resistance. However, the test results show that when they are arranged parallel to the traveling direction, the CSR shows a decrease of 0.15 or more, and the required slip resistance can be secured unless the ridges (3) are orthogonal to the traveling direction. Absent.

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.

Here, things that come into contact with the floor surface (1) include not only slippers and socks, but also bare feet and a hard rubber sole, and there are cases where it is dry, moist, or extremely wet. There are various conditions for contacting the floor surface (1), and in all of these cases, slip resistance must be exhibited.
By combining the gap between the ridges (3) appropriately wide and narrow,
When the distance between the ridges (3) is narrow, more ridges (3) contact the sole of the foot to enhance the anchor effect, and where the distance is wide, the sole of the foot contacts the floor surface (1). By increasing the contact resistance and efficiently coping with the difference in contact conditions by these cooperation effects, various designs can be constructed on the floor surface by combining these.

In addition, since the ridge (3) is an integrated body that is carved out from the flooring material, for example, it has a heavier weight than the ridge (3) made of rubber or the like and is used in ordinary households. 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 is easy to break during use. . Further, it is not preferable because it is likely to be chipped in production.
This width depends on the type of tree 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 synthetic resin injection material (so-called
WPC) can be used to further prevent damage and abrasion. 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, and 5 mm or more and twice the width of the ridges or less. Since they are combined as appropriate, slippery and sock slipperiness is all CSR 0.3 or more in the direction intersecting the ridges, showing effective anti-slip properties, and the direction of travel of people such as corridors and entrances and exits. Since the ridges of the floor material are constructed so as to intersect the direction of movement of the person on the floor where the ridge is almost constant, the ridges bite into the soles of the slippers and socks to create an anchor effect. Based on the scientific evidence that the soles of the slippers and socks enter the space between the wide ridges and come into contact with the floor surface at the same time that the slippery soles can be effectively stopped. There are advantages. 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 intersecting with each other, there is an advantage that water flows easily even when the floor surface is wet, it is easy to dry, and dust is easily removed and cleaning is easy. In addition, since the ridge is a one-piece product that is carved out from the flooring material, for example, it has a heavier weight than a ridge made by using rubber, etc. is there.

Also, the distance between the ridges is 2 to 4 times the width of the ridges and 5m
Since it is properly combined with those that are more than m and less than twice the width of the ridges, more ridges will contact the sole of the foot to enhance the anchoring effect in the place where the space between the ridges is narrow, and In a wide area, the soles of the feet come into contact with the floor surface to increase contact resistance, and there is an advantage that the cooperation effect of these makes it possible to efficiently cope with different contact conditions.
