Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface of a wooden tile used for a golf course hole, a promenade in a park, etc. The present invention relates to an anti-slip structure formed on the surface of a steel sheet and a method for forming an anti-slip coating film in the structure.

[0002]

2. Description of the Related Art A wooden tile is a piece of wood cut out in blocks, which has a certain size and is spread like a tile to form a floor surface. Floors constructed of wood tiles are stronger than floors constructed of normal wood and only a part of the floor can be easily replaced when cracked or worn, so shoes with spikes It is used for golf course holes and park trails that are often walked. As is the case with floors made of wood or synthetic resin, floors constructed with wooden tiles are also slippery when wet with water.

On the other hand, exercise equipment, especially exercise equipment used in gymnastics, is often made of wood, and among them, there are equipment having a wooden tread such as a reverse rising aid and a leveling board of a jump box. In such exercise equipment, if the foot slips on the tread, it becomes difficult to perform the desired exercise, and in some cases it is dangerous.

Further, in such exercise equipment, when a horizontal component force acts when stepped on, such as a railroad crossing plate, the railroad crossing plate placed on the floor of the gymnasium or the like slips on the ground contact surface. Depending on the situation, it will gradually shift.

In such a case, it becomes necessary to prevent the surface of wood such as the surface of the wooden tile or the tread of the exercise equipment from slipping. Conventionally, as a non-slip structure used in this type, it is known to apply a non-slip paint to the surface of wood. As the non-slip paint, there are known ones that form a rubbery coating film having a large friction coefficient, ones that contain sand, and the like.
Heretofore, this type of anti-slip coating has merely been applied to the wood surface.

[0006]

However, there is a problem that the coating may peel off. In particular, since many anti-slip paints have the first function of anti-slip, they often have insufficient adhesion to the wood surface. Therefore, in the conventional structure, the anti-slip coating film applied to the surface of the wood is peeled off or worn away by use, and eventually disappears.

Although not used in the field of anti-slip coating, characters or patterns are formed on the surface of wood by providing shallow grooves or recesses on the surface of wood and flowing colored paint into the grooves or recesses. Is being done. The structure with such grooves and recesses has not been used in the field of anti-slip coating because the coating surface is slightly recessed when the coating film dries. This is because the bottom does not come into contact with the unpainted wood surface and does not come into contact with the anti-slip coating film, and the anti-slip action is not sufficiently exerted.

Further, when the grooves and recesses on the wood surface are formed by saw teeth, milling cutters, milling cutters, etc., it takes time to process them and sufficient adhesion between the wood and the coating film can be obtained. There was a problem of not having.

An object of the present invention is to obtain a technical means which is particularly effective for preventing slippage of a wood surface such as a surface of a wooden tile or a tread of a wooden exercise equipment, and which can be implemented at low cost. .

[0010]

According to the present invention, a wooden surface such as a surface 2 of a wooden tile 1, a wooden rising surface 11 of a reverse rising aid 10 or a crossing board 13, and a wooden grounding surface 14 of a crossing board 13 are provided. A concave portion 9 having a raised bottom surface in the grain portion 15 is formed, and a coating film 3 having a coating surface raised from the surfaces 2, 11 and 14 is formed in the concave portion 9.

The coating film 3 having the above structure is formed on the surfaces 2 and 1 of wood.
Thicknesses 1 to 2 obtained by cutting out the portion where the recess 9 is formed in 1 and 14
mm rubber sheet 4 is attached, and the cutout 5 is sandblasted to form a recess 9 having an appropriate depth on the surface of the wood. When the rubber sheet 4 is attached, the recess 9 and It can be formed by pouring anti-slip paint into the cutout 5 portion of the rubber sheet. The rubber sheet 4 is peeled off after the anti-slip coating film 3 is formed.

Since the rubber sheet 4 can be easily cut out into a free shape by using a cutter or the like, a pattern of a free shape can be formed on the wood surfaces 2, 11, 14 by the non-slip coating film. It is also easy to express a multicolor pattern by mixing a pigment of a desired color into the anti-slip paint. It is also possible to form coating patterns by providing coating films 3 of different shapes and colors on the surfaces of adjacent wood. The formation of the combination pattern by such a method is particularly suitable for the wooden tile 1.
It is suitable as a non-slip structure.

On the exercise equipment, for example, the reverse rising assist tool 10 and the tread surface 11 of the level crossing plate 13, a slit-shaped or band-shaped recess 9 is provided in a direction orthogonal to the running direction of the athlete.
It is preferable that the anti-slip coating film 3 is provided in a striped or strip shape. In this case, if the tread surface 11 is divided into regions by the color coding of the anti-slip coating film 3, it is useful for understanding the goal of skill acquisition and progress, and for judging the achievement level of the technology.

[0014]

In the present invention, since the unevenness is formed by using the wood grain 15 on the bottom surface of the recess 9 to which the anti-slip coating is applied, the adhesive force between the wood and the coating film 3 increases, and the coating film 3 Is less likely to peel off. Further, the recess 9 can be easily formed by the method of the present invention.

Further, according to the present invention, by coating the surface of the wood with the rubber sheet 4 provided with the cutouts 5 attached, the coating film 3 having a raised coating surface on the surfaces 2, 11 and 14 of the wood 3 As a result, the contact pressure between the shoe sole of the pedestrian or the athlete and the anti-slip coating film 3 is large, and a sufficient anti-slip action can be exhibited.

Further, according to the method of the present invention, since the rubber sheet 4 used for defining the contour of the recess 9 is used as it is to raise the coating film 3, the coating film 3 is formed. It is possible to form the coating film 3 having a precise planar shape with few steps. Further, by forming the recess 9 with sandplast, it is easy to form the recess 9 and the wood grain 1
It is possible to form a recess having an uneven bottom surface according to No. 5 without applying any special technical means.

[0017]

1 and 2 show an embodiment in which a surface 2 of a wooden tile 1 is provided with a non-slip structure of the present invention. As shown in FIG. 1, a plurality of wood tiles 1 are arranged vertically and horizontally to form a floor surface, and a coating film 3 having a different planar shape is formed on each surface 2 of the blocks, so that the floor tile surface has a constant overall thickness. A combination pattern of is formed.

In such a wooden tile 1, a plurality of wooden tiles 1 are arranged, a rubber sheet 4 (see FIG. 3) having a desired pattern cut out is attached to the surface thereof, and a sand plast 6 is applied to the cutout 5 portion, After that, while the rubber sheet 4 is still attached, the anti-slip paint 8 is poured into the recess 9 formed by sandblast and the cutout 5 of the rubber sheet by the painting roller 7 or the like to solidify the anti-slip paint 8 and then the rubber sheet. It can be formed by peeling off 4.

The non-slip coating film 3 thus formed
Is formed in a raised state in the concave portion 9 having an uneven bottom surface, so that the thickness of the coating film is large and therefore the durability against abrasion is high. In addition, since the adhesion between the coating film 3 and the wooden tile 1 is improved due to the unevenness of the bottom surface, it is difficult to peel it off.
Furthermore, when the coating film 3 dries in the cutout 5 of the rubber sheet 4, the edge portion of the coating film that rises due to the contraction becomes a smooth curved surface, so that the corner portion of the coating film is caught on the shoe sole or the like and peels off. There is no problem.

FIGS. 4 and 5 show an example in which the anti-slip structure of the present invention is applied to the wooden tread 11 of the reverse rising aid. The reverse rising assisting tool 10 has a stepped surface 11 having a concave shape formed by a large number of cross bars 12.
A lateral strip-shaped recess 9 is formed on the tread surface 11, and the strip-shaped coating film 3 is formed by the same method as shown in FIG.

In the case of such a reverse rising assisting tool, the height of the tread surface is divided into three areas, and the color of the anti-slip coating film 3 is made different for each area, so that the achievement of the technique can be facilitated. You will be able to recognize.

That is, the reverse rising aid shown in the figure is installed under the iron bar so that the student can learn the reverse rising while climbing up on the tread 11, but the student can climb up higher. As the ability to do so is improved, the technique will be improved, and eventually it will be possible to go up even without using the assisting tool 10. The color coding of the anti-slip coating on the tread is an index for judging how high the student could climb.

FIG. 6 shows an example in which the slip prevention structure of the present invention is applied to a railroad crossing plate. In this example of the railroad crossing plate 13, a non-slip coating film 3 having the same shape as the reverse climbing auxiliary tool 10 is formed on the tread surface 11, and the ground contact surface 1
4 is also provided with a non-slip coating film (not shown in the figure) having the same shape as the tread 11. That is, in the level crossing plate 13, when a player steps on the level crossing plate 13, a horizontal force as well as a vertical force acts on the level crossing plate 13.
Since the player moves on the floor surface, it is necessary to prevent the athlete's foot from slipping and also to prevent the level crossing plate from moving. The slip stopper of the present invention is provided on both the tread surface 11 and the ground contact surface 14. The structure is adopted.
