Description

Rubber mat for groun of childrens's playground}

The present invention relates to a children's playground elastic mat that can be mainly installed in a park including a playground to improve the elasticity, durability and shock absorption so as not to impact the foot of the pedestrian or the athlete during walking and exercise.

In general, a children's playground refers to a place provided outdoors for children to play safely, and the playground is provided with various play equipment for children to enjoy.

In addition, children's playgrounds are installed in the village's vacant lands, local parks, and newly built residential complexes. There are construction regulations for safety when creating such parks or children's playgrounds, which have been strengthened since 2008. ,

Among the construction regulations, the floor must have a good shock absorption rate so that children can fall off the play equipment and prevent accidents.

In particular, in the case of a playground where children play, if they do not have sufficient elasticity, they may not only damage the joints of the children's knees, etc., but may also hurt the child due to the impact of falling. It should be constructed to have elasticity more than predetermined reference value.

Thus, in consideration of the hygiene problems and safety of children's playground floor using sand or soil, flooring made of a rubber chip having a safe and elastic force is widely used.

Therefore, after applying the primer on the concrete or asphalt ground as a playground flooring material, rubber tires or foamed rubber chips, which are pulverized waste tires, are mixed with a polyurethane binder and installed at a fixed ratio, and then compacted with a hot roller.

In this case, various colors and patterns may be formed by mixing color chips of various colors, such as urethane rubber, with a binder on the top of the rubber chip layer in consideration of the environment and aesthetics of the elastic flooring material.

Although the elastic flooring has the advantage of clean and clean surface, the shock absorption rate is not satisfactory, and in order to satisfy the impact test standard of the play facility, sand is added to the floor or packed with elastic chips with a thickness of 10 to 15 cm or more. You have to do this.

In order to solve the above problems, the present invention provides an elastic mat for a children's playground that can improve elasticity, durability, and shock absorption to improve shock absorption by absorbing shock by improving the structure of a conventional elastic flooring.

The present invention as a solution to the above problems is a dual structure consisting of the upper elastic layer and the lower buffer layer is provided with a buffering projection in the center on the bottom of the lower buffer layer to maximize the elastic force as well as absorb and cushion the shock transmitted from the upper The cushioning space portion provides an elastic mat for a playground arranged with a buffer passage therebetween.

As described above, the present invention has sufficient elasticity to improve elasticity, durability, and shock absorbing ability to absorb and cushion shocks by arranging buffer protrusions capable of sufficiently buffering the upper load to prevent safety accidents of children. It works.

In addition, there is an effect that the construction of the children's playground can be easily constructed to maintain the appropriate elasticity of the flooring material for the sports facility and the walkway, the flooring material for children's playgrounds and to increase the sliding resistance to improve the performance and safe use when using the sports facility.

The present invention is described in detail by the accompanying drawings in order to achieve the above objects and effects are as follows.

1 is a bottom perspective view showing the present invention elastic mat, Figure 2 is a bottom view showing the present invention elastic mat, Figure 3 is a cross-sectional view showing the present invention elastic mat, Figure 4 is the present invention elastic Bottom perspective view of the mat.

The elastic mat (1) of the present invention is square, and the surface of the upper elastic layer (2) has various colors, and the appropriate combination of these colors can provide the desired shape and color to the children's playground floor, which is more attractive to children. Provide space.

In addition, such an elastic mat (1) can be usually manufactured using waste tire rubber chips, after grinding the waste tire chips or various rubber resins, and then mixed with the crushed resin resin curing agent and melted to a desired shape In addition to molding through molds, waste tire rubber chips can be used to prevent environmental pollution by enabling the recycling of resources.

Therefore, the present invention elastic mat (1) consists of a bonding structure in which the upper elastic layer (2) and the lower buffer layer (3) is laminated.

The upper elastic layer 2 is formed in a plate shape by mixing a rubber chip and a hardener having a size of 1 to 2 mm so as not to pinch a woman's shoe heel or an umbrella, as well as maximizing the elastic force, and the upper elastic layer 2 In the lower part, a rubber chip having a size of 7 mm is mixed with a curing agent and molded in a laminated state.

Further, in the state where the buffer space portion 5 having the buffer protrusion 4 is arranged at the inner center at a predetermined interval on the bottom surface of the lower buffer layer 3, the buffer space portion 5 is partitioned so as to cross in a square shape. To form a buffer passage 7 inward.

In addition, the upper elastic layer 2 and the lower buffer layer 3 may be molded by varying the size of the rubber chip to maximize the elastic force of the upper and lower.

That is, since the upper elastic layer 2 has a rubber chip size of 1 mm to 2 mm, it maintains a close state and thus improves durability due to the uniformity of the entire surface. The elastic force can be maximized while supporting the upper elastic layer 2.

In addition, the buffer space portion 5 formed in the lower buffer layer 3 provides elasticity to absorb and buffer the load and shock transmitted from the upper portion, as well as the buffer space portion 5 is a buffer protrusion (4) located at the inner center. ) Absorbs the shock and disperses it to the bottom to absorb and buffer it.

In addition, the buffer space portion 5 positioned at the bottom edge portion integrally forms the auxiliary buffer space portion 6 partially through which the hole is diagonally facing toward the edge to maximize elasticity at the edge portion.

The reason for this is that generally, when the elastic force of the elastic mat 1 is examined, the elastic force is obtained by performing an impact test on the corner portion where the four elastic mats 1 meet while the elastic mat 1 is in close contact with the front, rear, left and right sides. In order to secure the expansion and cushioning space to ensure.

Therefore, the elastic mat 1 is induced to reinforce the edge portion of weak elasticity and elasticity.

In addition, by partitioning the buffer space portion (5) to cross in a rectangular shape to form a buffer passage (7) inwards as well as the drainage passage function as well as the elasticity between the buffer space portion 5 can be secured elasticity and buffer force It can be maximized.

In addition, when the impact applied to the upper elastic layer 2 is transmitted to the lower buffer layer 3 in the first buffered state, some are distributed to the buffer space part 5, and some are transmitted to the buffer protrusion 4 to cushion the shock. At the same time, the expansion and cushioning space is secured between the buffer space part 5 and the buffer protrusion 4, and a buffer passage 7 is formed between the buffer space part 5 to maximize the buffering force.

FIG. 5 is a perspective view showing the decomposed elastic mat, which is arranged on the playground floor so that the upper elastic layer 2 of the elastic mat 1 is located on the upper surface to provide a uniform upper surface to provide a beautiful floor. .
