DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mushroom. More specifically, the present invention is a snowboard which is rich in elasticity and excellent in walking sensation, and can be used not only in places around water such as poolsides and bathrooms, but also in crossing corridors, indoors, etc. The present invention relates to a snowboard which can be injured or the like even if it falls down during walking or can be minimized. Also,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snowboard having an enlarged area obtained by combining a plurality of single snowboards.

[0002]

DESCRIPTION OF THE RELATED ART Conventionally, a snowboard (Ukonoko) has been used for a bathroom floor, a sink, a corridor, a dressing room, a closet floor, and the like.
Sunoko was initially lined with split bamboo, round bamboo, or narrow boards, but later, rigid polyvinyl chloride or polyolefin resin was widely used because it was cheap and suitable for mass production. Was.

[0003] Nowadays, snowboards are widely used not only in places such as bathroom floors, dressing rooms, push-in floors, etc. where water or moisture is disliked, but also in floors of kindergartens, amusement parks, schools, hospitals, and other facilities, corridors, and the like. It is coming.

[0004] Bathrooms, dressing rooms, etc. are relatively limited spaces and are used by limited people.
Institutions such as schools and hospitals are used by an unspecified number of people from infants to the elderly and from healthy to unhealthy people. Therefore, when using a mushroom in a facility such as a kindergarten, amusement park, school, hospital, etc., it is necessary to consider the safety such as laying of the mushroom and safety when walking compared to using it in a bathroom, a dressing room, etc. is necessary.

[0005] However, conventional plastics such as polyvinyl chloride and polyolefin are hard and have poor followability to the surface shape of the floor, so that they may deviate from a fixed position after laying and cause an accident. There are drawbacks such as an accident such as an injury due to damage, a lack of a stress absorbing power, a crack or the like caused by rough handling, resulting in poor durability, and a fading due to long-term exposure to ultraviolet rays.

[0006]

Accordingly, a first problem to be solved by the present invention is that, in the conventional hard resin snowboard, the followability to the floor surface shape is improved so that the displacement from a fixed position after laying is improved. That could not be prevented.

A second problem to be solved by the present invention is that, in the case of a conventional hard resin snowboard, when it falls down or jumps down, it can prevent the occurrence of accidents such as injuries by absorbing the stress caused by impact. It was not.

A third problem to be solved by the present invention is that, in the case of a conventional hard resin type snowboard, when the snowboard is brought into contact with furniture, a building, etc., it absorbs impact stress to prevent cracks and the like from being generated. And the durability could not be improved.

A fourth problem to be solved by the present invention is that the conventional hard resin snowboard cannot prevent quality deterioration due to discoloration, deterioration of the plasticizer, and the like when exposed to ultraviolet rays for a long period of time. It is.

[0010] Other problems and advantages to be solved by the invention will be clarified below.

[0011]

Means for Solving the Problems The present inventors have solved the above-mentioned problem by changing the material of hardwood from hard polyvinyl chloride to rubber, and making the front and rear surfaces of a specific shape and shape.
The design to the structure was considered.

The present invention, which has been achieved as a result of solving the above-mentioned problems, is a rubber or thermoplastic elastomer snowboard having a predetermined shape and thickness, which is rich in elasticity. A convex portion and a concave portion having a predetermined width are sequentially arranged on the surface of the mushroom, and at least one surface of the convex portion is formed with a projection having both a design effect and an anti-slip function. At least one through hole drilled in the thickness direction of the snowboard is formed on the bottom surface, and a space of a predetermined height is formed on the back surface of the snowboard with the surface on which the snowboard is laid. This is a snowboard having a plurality of legs formed continuously or discontinuously in the longitudinal direction of the snowboard.

In the present invention, the rubber used as the material of the snowboard is preferably natural rubber, various synthetic rubbers, thermoplastic elastomers or a mixture thereof. For the purpose of cost reduction, natural rubber, various synthetic rubbers and synthetic resins such as polyvinyl chloride are preferable. Can also be used. When a mixture of natural rubber and another material is used as the material for the saw, the natural rubber is preferably blended in an amount of 15 to 60% by weight of the mixture.

The hardness of the snowboard of the present invention is JIS A 40
The range of from to 60 is preferable. The hardness of the snowboard of the present invention is J
In the case of IS A 40 or less, the followability to the surface shape of the floor to be laid is improved, but it is not preferable because it may be too soft and dangerous on the contrary, and the function as a snowboard is not exhibited. In the case of 60 or more, it becomes hard, and not only does the followability to the surface shape of the floor to be laid deteriorate, but also the above problem cannot be solved.

[0015] On the surface of the snowboard of the present invention, irregularities are sequentially formed. In the present invention, "sequentially" means that uneven portions are alternately formed, and does not necessarily mean regular, but if safety is ensured, irregular arrangement may be performed for the purpose of a design effect. Can also.

In the case of forming a convex portion and a concave portion on the surface of the snowboard of the present invention, it is important how to set the width of the convex portion and the concave portion in particular. Each width of the concave portion and the convex portion may be the same when the width is narrow, but when the width of the concave portion is too wide,
Toes or heels fall down and hinder walking. Conversely, if they are too narrow, drainage and cleaning will be hindered. In consideration of walking safety, the width of the concave portion is preferably smaller than the width of the convex portion,
More preferably, it is smaller than the size of the foot of a walkable infant. Considering various conditions such as walking safety, drainage and cleaning, the width of the concave portion is preferably in the range of 2 to 4 cm. Also,
The width of the projection is 6 considering the walking feeling and walking safety.
It is preferably in the range of 12 cm to 12 cm.

The projections formed on the surface of the convex portion of the snowboard of the present invention are intended for design and anti-slip function, and may be molded integrally with the snowboard or manufactured separately and adhered. In the case of a pattern, an arbitrary pattern such as a flower pattern, an animal, a geometric pattern, or the like can be formed according to the requirements of the facility where the mushroom is laid. In the case of a projection, points, lines, streaks, or combinations thereof are preferred.

The through hole formed in the bottom surface of the concave portion of the snowboard of the present invention in the thickness direction of the snowboard is for drainage. The through-holes may be independently formed one by one, but the drainage effect can be improved by connecting the through-holes with the grooves on the back surface of the saw.

A groove may be formed in the bottom face of the concave portion of the snowboard of the present invention in the longitudinal direction of the snowboard. This groove is for enhancing the drainage effect on the surface of the mushroom. That is, water or rainwater, etc., when washing the mushroom are first dropped into the groove, and the bottom of the groove is drained to the back of the mushroom by a through hole formed in the width direction of the mushroom. Therefore, if a groove is formed on the bottom of the concave portion of the mushroom, a larger amount of water is drained by both the concave portion and the groove, and water does not stay on the surface of the mushroom. Is secured. In addition, the drainage function can be improved by connecting the through holes to each other by the connecting groove on the back surface of the saw.

The mushroom of the present invention can be used alone,
It can also be used as a souvenir having a so-called enlarged area in which two or more sheets are combined. When two or more pieces are used in combination, the through holes at adjacent ends of the combined mushrooms may be connected to each other from a back surface of the mushrooms using a connection tool having a predetermined shape.

[0021] The shape and structure of the connecting tool when two or more of the mushrooms of the present invention are used in combination so as to straddle the edges of the mushrooms on the back surface of the mushrooms. Although is not particularly limited, for example, it is preferable to have a structure having, at both ends thereof, protrusions having substantially the same shape as the through hole and press-fit into the through hole from the back surface of the saw blade and fitted into the through hole. The material of the connecting device is preferably made of the same material as the snowboard so that when a large unexpected load is applied to the connected snowboard, the load can be absorbed.

The leg formed on the back surface of the snowboard of the present invention forms a space between the floor and the floor on which the snowboard is laid, of a predetermined height for the purpose of absorbing shock, draining water, and the like. As the length of the legs increases, the depth of the space formed between the mushrooms and the surface on which the mushrooms are laid increases, and the amount of sinking when weight is applied to the mushrooms increases. However, if the amount of sinking becomes too large, a disadvantage occurs. Therefore, the length of the leg formed on the back surface of the mushroom should be determined by comprehensively considering the shape, weight, thickness, hardness, floor surface to be laid, etc. of the mushroom.

The shape of the mushroom of the present invention is not particularly limited, but is generally preferably rectangular. As described above, the snowboard of the present invention can be used as a so-called unit object, even if it is manufactured as a single piece, or used in conjunction with the shape and size of the floor surface to be manufactured and laid in a strip shape. It is.

The weight of the snowboard of the present invention is not limited since it is determined depending on the size and shape, but it is necessary to have a weight such that it has stability by its own weight when it is laid. Since it may be used around water, its specific gravity is preferably in the range of 1.3 to 1.6. For the same reason, it is preferable to impart a fungicide function.

An embodiment will be described below with reference to the accompanying drawings. In addition, an Example shows one of the preferable aspects of this invention, and the material or size, shape, weight,
It is well understood by those skilled in the art that the design such as specific gravity and numerical elements are not limited to these.
