Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sludge placed on a floor surface (installation surface) of a locker room, a factory, a warehouse, a veranda, a bathroom, or the like.

[0002]

2. Description of the Related Art In addition to wood, synthetic resin materials such as polyvinyl chloride, polypropylene, polyethylene, etc. are used instead of wood for slats placed on the floor surface (installation surface) of locker rooms, factories and warehouses, balconies, bathrooms, etc. What is manufactured by combining the long materials of is also already known. This sludge is formed by connecting a plurality of slender saw bodies formed of the synthetic resin material in a rectangular shape in the width direction in the state in which a gap is opened at predetermined intervals via a spacer by a joint connecting member. For example, an installation contact portion to be installed on the floor surface on which the sludge is placed is formed integrally with the spacer so as to project downward. The spacers and connecting members are made of semi-rigid polyvinyl chloride.

[0003]

However, according to the above conventional construction, the hardness of the installed contact portion made of polyvinyl chloride is about 90, and the friction coefficient with respect to a general floor surface is 1.0. Since the sludge itself is smaller than this, the sludge itself may slip on the floor surface, which may cause a person to fall or the load placed on the sludge to collapse as the sludge moves. Met.

Further, in this type of saw, since the main body of the saw is integrally formed of the synthetic resin material, a person walking on the article or the saw placed on the saw slides on the saw. Even if this occurs, there is a risk that a person may fall or the load placed on the drainboard may collapse.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a soot that does not cause danger.

[0006]

In order to solve the above-mentioned problems, the first aspect of the present invention is that the sludge has a hardness of 40 to 8 at an installation contact portion installed on an installation surface such as a floor surface.
The coefficient of sliding friction with respect to the floor is 1.0 to 2.0.

In addition, the second aspect of the present invention, the sludge is provided with a plurality of protrusions made of a soft material on the upper surface of the sludge body. In addition, the sludge as the third means of the present invention is, in the above-mentioned second means, forming a plurality of hole portions having a bridging portion connecting a plurality of points around the upper surface portion of the saw body, A projecting part made of a soft material is provided so as to cover the bridging part from the surroundings, and adjacent projecting parts are integrally molded in a state of being connected via a connecting part.

[0008]

According to the first means, since the hardness of the installation contact portion installed on the installation surface is 40 to 80 and the coefficient of sliding friction with respect to the floor surface is 1.0 to 2.0, the slats are installed on the installation surface. As a result of the movement of the drain, it is possible to prevent a person from falling down or the load placed on the drain from collapsing.

Further, since a plurality of protrusions made of a soft material are provided on the upper surface of the sludge body by the second means,
An article placed on the sludge or a person walking on the sludge will not slip on the sludge, and as a result, a person will fall or the load placed on the sludge will collapse. Is prevented.

Further, by the third means, a protrusion made of a soft material is provided so as to cover the bridging portion from the surroundings, and the adjacent protrusions are integrally molded in a state of being connected to each other through the connecting portion. As a result, the protrusion can be more securely fixed to the upper surface of the drainboard body.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, a drainboard 1 according to the present invention.
Is configured by connecting a plurality of substantially square-shaped sludge units 2 which are detachable from each other. Sunotoko Unit 2
Is integrally formed in a posture in which three elongated parts (slat main bodies) 3 which are elongated in one direction are arranged in parallel with each other with a gap provided at predetermined intervals via a spacer part 4.

Installation contact portions 5 are provided at the four corners of the bottom surface of the elongated portion 3, and the sludge unit 2 is installed on the floor surface which is the installation surface through the installation contact portions 5. ing. Installation contact part 5 has its hardness (Shore hardness)
Of 60 to 80 and a sliding friction coefficient at room temperature to the floor surface of 1.0 to 2.0 (for example, 1.42 for steel sheets and 1.62 between the materials), a crosslinked chlorinated ethylene copolymer alloy Is a thermoplastic elastomer (ALCRYN: registered trademark of DuPont, USA). As a material for the installation contact portion 5, vinyl chloride having a hardness of 40 to 80 and a coefficient of friction with the floor surface at room temperature of 1.5 to 2.0 may be used instead of the alkrin, and a polyolefin-based material. It may be an elastomer, a styrene elastomer or a urethane elastomer. As shown in FIG. 5, the installation contact portion 5 has a substantially triangular shape, and the triangular columnar portions 5a are inserted and attached to the recesses 3a provided at the four corners of the bottom surface of the elongated portion 3.

As shown in FIG. 5, FIG. 7, FIG. 8, etc., there are three convex portions 6 and three concave portions 7 for connecting the sludge units 2 to each other on two adjacent sides of the sludge unit 2. Spacer portions 6a having a function of a spacer are also formed on the convex portion 6, and the long portions 3 of the adjacent sludge units 2 are also arranged with a similar gap. Then, each protrusion 6b of the convex portion 6
It is adapted to be fitted in the groove 7a.

Further, as shown in FIG. 6 to FIG. 9 and the like, four protrusions 8 made of the same material as the above-mentioned installation contact portion 5 are alternately provided on the upper surface of the elongated portion 3. . That is, a plurality of round holes 9 are formed in the upper surface of the elongated portion 3 which is the main body of the sludge, and a cross-shaped bridging portion 9a that connects four surrounding portions is integrally formed in the round hole 9. ing. Then, the forming material of the protruding portion 8 is injection-molded in the round hole 9 so as to cover the bridging portion 9a from the surroundings, and the long portion 3 is formed.
It is fixed in a slightly raised state from the upper surface of the.
Here, the adjacent protruding portions 8 are integrally connected to each other on the rear surface side of the upper surface of the elongated portion 3 via the connecting portion 8a so that the protruding portion 8 is securely fixed to the elongated portion 3. There is.

The parts other than the installation contact part 5 and the projection part 8 of the sludge unit 2 are integrally formed of polyolefin resin such as polypropylene. Reference numeral 10 in FIGS. 4, 5, 7, and 9 is a reinforcing rib formed on the back surface of the elongated portion 3.

With the above structure, since the hardness of the installation contact portion 5 installed on the floor surface is within the range of 40 to 80 and the friction coefficient with respect to the floor surface is 1.0 to 2.0, the ground of the sludge 1 is grounded. The performance is improved so that it does not slip on the floor surface, and as the sludge 1 moves, a person falls on the sludge 1 or the load placed on the sludge 1 collapses as the sludge 1 moves. Can be prevented.

A plurality of protrusions 8 are also provided on the upper surface of the sludge 1. The hardness of the protrusions 8 is in the range of 40 to 80 and the friction coefficient with respect to the floor is 1.0 to 2.0. Therefore, it is possible to prevent a person, a load, or the like from sliding on the drainboard 1.

Incidentally, in this sludge 1, as shown in FIG. 10, it is possible to connect the sludge units 2 so that the elongated portions 3 are continuous, but as shown in FIG. It is also possible to connect the long portions 3 so as to be orthogonal to each other, and when arranged in this way, it is possible to prevent sliding along the groove between the long portions 3.

Here, the installation contact portion 5 and the protruding portion 8 are
If the hardness is less than 40, it is too soft
Is easily moved, and when it is larger than 80, it is too hard to easily transmit vibrations from the floor surface through the slats 1,
It is not suitable for you. Further, when the friction coefficient is less than 1.0, it is slippery, and when the friction coefficient is more than 2.0, it is extremely unfavorable because it is likely to be caught in a contacting place.

Further, since the projecting portion 8 is provided so as to cover the cross-shaped bridging portion 9a from the surroundings and the adjacent projecting portions 8 are integrally molded in a state of being connected to each other through the connecting portion 8a, the projecting portion 8 is formed. It is possible to reliably prevent the portion 8 from coming off the long portion 3, and it is securely fixed to the upper surface portion of the long portion 3. And
In this way, while the protrusion 8 can be securely fixed to the upper surface of the elongated portion 3, the hole of the elongated portion 3 is formed into the shape of the round hole 9a, and a groove portion or the like is formed between the round holes 9a of the elongated portion 3. Since the protrusions 8 are connected without forming the holes, the holes of the elongated portion 3 are formed into a square hole shape or structurally compared with the case where a groove portion is formed between the round holes 9a of the elongated portion 3. The strength can be secured and the reliability is improved when a large load is applied.

Furthermore, by performing injection molding in a state in which the formation portion of the protruding portion 8 is covered with a mold, the protruding portion 8 can be formed in a small number of steps, and the shape of the protruding portion 8 can be freely changed. Therefore, it is also possible to obtain a sludge with a high design.

Further, since the projecting portion 8 is made of a soft material, if a large amount of weight is loaded when the projecting portion 8 is inserted by simply providing a hole, the location of the projecting portion 8 will be dented due to elasticity. As a result, the anti-slip effect is reduced, but as described above, the round hole 9 has four holes around it.
Since the cross-shaped bridging portion 9a that connects the points is integrally formed, the load on the protrusion 8 is supported by the bridging portion 9a,
It is also prevented that the anti-slip effect is reduced.

As a separate method of providing the non-slip portion on the upper surface of the soot, it is conceivable to provide a groove portion on the upper surface of the main body of the saw and adhere the anti-slip tape to the groove portion with an adhesive material. In this case, the step of attaching the non-slip tape by hand or the like is required, which is troublesome, and the anti-slip tape is separated due to aging due to deterioration of the adhesive material. On the other hand, according to the present invention, it is possible to surely fix the protrusion 8 for slip prevention without using an adhesive or the like in a small number of steps.

In the above embodiment, the case where the installation contact portions 5 are provided at the four corners of the bottom surface of the elongated portion 3 has been described.
The present invention is not limited to this, and any location may be used as long as it is placed in contact with the floor surface. In addition, the protruding portion 8 is also the long portion 3
It only needs to be exposed from the upper surface of the. Furthermore, in the above-described embodiment, the case where the protruding portions 8 of the elongated portion 3 are arranged in a zigzag pattern at four places is shown, but they may be provided at the positions indicated by imaginary lines in FIG.

[0025]

As described above, according to the present invention, the hardness of the installation contact portion installed on the floor surface is 40 to 80 and the sliding friction coefficient with respect to the floor surface is 1.0 to 2.0. With this configuration, the ground contact performance of the sludge is improved, and it does not slip on the floor surface, so that people can fall on the sludge or place it on the sludge in the same manner as in the past. It is possible to prevent the load from collapsing.

Further, since a plurality of projections made of a soft material are provided on the upper surface of the main body of the sludge, an article placed on the sludge or a person walking on the sludge does not slip on the sludge. It is possible to prevent a person from falling down or a load placed on the drainboard from collapsing due to the above.

Further, by providing a protrusion made of a soft material so as to cover the bridging portion from the surroundings and integrally molding the adjacent protrusions connected to each other through the connecting portion,
The protrusion can be securely fixed to the upper surface of the sludge main body, and the member for preventing slippage does not separate from the slip due to secular change as in the case of fixing with an adhesive.
