 The present invention relates to an elastic laying body in which a component having an arbitrary shape is integrally formed at an arbitrary position, particularly, a playground equipment and a playground equipment installed in a kindergarten, a nursery school and related facilities, a park, a playground, and the like. The present invention relates to an elastic laying body capable of preventing peripheral safety measures, beautifying the environment, and preventing danger caused by falling or falling.

[0002]

[Prior art]

 Conventionally, as this kind of elastic laying body, for example, a mat or a block laid in a park or a walking path is known, and it can be spread over a laying area such as a park or a walking path. . In recent years, in particular, it has become mandatory to implement safety measures around playground equipment such as kindergartens, nursery schools and related facilities, parks and amusement arcades, and to prevent dangers due to falls and falls. There is a growing need for elastic laying bodies depending on the application. Furthermore, from the viewpoint of beautifying the environment, elastic laying bodies are required to have pictures, numbers, characters, and designs that match the environment around the playground equipment.

[0003]

[Problems to be solved by the invention]

 However, conventional elastic laying bodies generally have a single color and a rectangular shape, so there are limits to simultaneously taking measures for safety, preventing dangers such as falling or falling, and simultaneously beautifying the environment. Specifically, in the conventional laying method, after an elastic laying body of a predetermined color is laid around a certain playground equipment, the desired pattern, number, character, or design must be overcoated on the surface by another process. However, there is a problem that it takes time and effort to complete the product, and costs for another process. Further, in this method, since letters and designs are merely overcoated, there is a problem that they are easily peeled and worn due to fatigue and aging due to long-term use.

As another laying method, there is known a method in which different types (colors, materials, etc.) of rubber materials are poured into a peripheral area of a certain playground equipment along a character, a design, or the like, and solidified. Although this method can express characters and designs that meet the needs for durability, the method of pouring rubber material takes a lot of time and effort, and increases production costs. There is. Furthermore, when there is a request for maintenance (for example, change or correction) of text or design, it is difficult to correct only the maintenance part. There is also a problem that the rubber material must be poured from the beginning, and it is not possible to quickly respond to maintenance requests. The present invention has been made to solve such a problem, and its purpose is to provide safety measures, prevent dangers such as falling or falling, etc., and at the same time provide a low-cost, durable environment that meets the needs. An object of the present invention is to provide an elastic laying body excellent in easiness and maintainability.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the elastic laying body of the present invention is provided with a laying body that can be integrally formed with a desired elastic material, and the laying body has a structure of an arbitrary shape. Is integrally formed at an arbitrary position. In this case, by performing press vulcanization while the elastic material is placed in a predetermined laying mold, the constituent body is integrally formed with the laying main body. The laying die is composed of a laying die for the main body for molding the laying main body, and a laying die for the structural body for molding the structural body. The elastic laying body in which the components are integrally formed on the laying body by press vulcanization has at least impact resistance, abrasion resistance, heat resistance, cold resistance, oil resistance, water resistance, and ozone resistance. In addition, it has water permeability. The elastic material is composed of a plurality of small pieces having at least impact resistance, abrasion resistance, heat resistance, cold resistance, oil resistance, water resistance, and ozone resistance. By adhering these small pieces to each other via an adhesive, the component is integrally formed on the laying main body. In the laying main body, at least desired pictures, numbers, characters, and designs are expressed by the components. Further, the same type of elastic material or different types of elastic materials can be used for the laying body and the structural body. Further, the elastic material can be filled with any type of adhesive and any colorant. The colorant includes a colorless colorant and a colored colorant.

[0006]

[Embodiment of the invention]

 Hereinafter, an elastic laying body according to an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1A, the elastic laying body 2 of the present embodiment includes a laying main body 4 that can be integrally molded with a desired elastic material. -Shaped components 6, 8 are integrally formed at arbitrary locations. The elastic laying body 2 is configured to be used alone or in combination.

In the present embodiment, as an example, a rectangular elastic mat 2 is assumed as the elastic laying body 2, and this elastic mat 2 has one heart-shaped The component 6 and four star-shaped components 8 are integrally formed. The laying main body 4 includes a base portion 4a and a main body portion 4b, and the heart-shaped and star-shaped components 6, 8 are integrally formed with the main body portion 4b. The base 4a is formed of a relatively hard elastic material, and the main body 4b is formed of a relatively soft elastic material. The combination of the hard and soft elastic materials provides strength (durability). An elastic mat (elastic laying body) 2 having both flexibility (flexibility) is realized.

In the present embodiment, the laying main body 4 (base portion 4a, main body portion 4b) and the structural members (heart-shaped structural member 6, star-shaped structural member 8) are the same type of elastic material or different types. It is possible to select and use the elastic material appropriately. That is, any elastic material that can form the laying main body 4 and the components 6, 8 can be used regardless of the type. In this case, for example, if elastic materials of different kinds are used, the laying main body 4 and the components 6, 8 having different tactile sensations can be formed. This assumes, for example, a case where a certain part is made harder or softer than the other part (when the tactile sensation is changed), and can be set to an arbitrary tactile sensation according to the purpose of use or application.

The elastic material used for the laying main body 4 (base portion 4a, main body portion 4b) and constituent bodies (heart-shaped constituent body 6, star-shaped constituent body 8) is filled with an arbitrary kind of adhesive. It is possible to do. As the adhesive, a commercially available adhesive can be used, but any kind of adhesive can be used as long as the elastic material can be filled. With this adhesive, the laying body 4 and the components 6, 8 can be firmly integrated with each other. In the present embodiment, an elastic material filled with an adhesive is used. However, the present invention is not limited to this. The effect can be obtained. That is, a predetermined adhesive is mixed during the manufacturing process without filling the elastic material itself with the adhesive, and the laying main body 4 and the components 6, 8 are firmly integrated with each other.

Further, the elastic material of the laying main body 4 (base portion 4a, main body portion 4b) and constituent bodies (heart-shaped constituent body 6, star-shaped constituent body 8) are filled with an arbitrary type of coloring agent. It is possible. As the colorant, a commercially available colorant can be used, but any type can be used as long as it can be filled in the elastic material. The color of the colorant includes both colorless (transparent) and colored, and any color can be selected according to the color of the use environment and the needs of the user. With this coloring agent, the laying body 4 (the elastic laying body 2, that is, the elastic mat 2) expresses a design rich in color change by the constituents (heart-shaped constituents 6 and star-shaped constituents 8). In the present embodiment, an elastic material filled with a colorant is used, but the present invention is not limited to this. For example, the same applies when a colorant is mixed in a manufacturing process step as described later. The effect of can be obtained. In other words, the elastic material itself is not filled with a coloring agent, and a predetermined coloring agent is mixed during the manufacturing process to express a design with a rich color change.

Here, a manufacturing process of the above-described elastic laid body (rectangular elastic mat) 2 will be described with reference to FIGS. 1B to 1D. In the manufacturing process of the present embodiment, by pressing the vulcanization treatment in a state where the elastic material is put in a predetermined laying mold, the structure (heart-shaped) together with the laying main body 4 (base portion 4a, main body portion 4b) is provided. The structure 6 and the star-shaped structure 8) are integrally formed. The laying die of the present embodiment includes a laying die 10 for the main body for forming the laying main body 4, a laying die 12 for the heart-shaped component for forming the heart-shaped component 6, and a star-shaped laying die. And a laying die 14 for a star-shaped component for molding the component 8 of the present invention.

In the present embodiment, press vulcanization is a process in which an elastic material is mixed with an appropriate amount of an insulator (for example, sulfur) and heated to combine the elastic material with sulfur. In this press vulcanization, it is preferable to add, for example, a reinforcing agent (carbon black), an antioxidant, and the like, in addition to the above-mentioned adhesive and colorant. The elastic material preferably has at least impact resistance, abrasion resistance, heat resistance, cold resistance, oil resistance, water resistance, and ozone resistance. In this case, as the elastic material, for example, a rubber chip obtained by crushing waste tires or other waste rubber products into chips (small pieces) of a desired size, or a material obtained by melting waste rubber products is used. If used, it is very effective from various viewpoints such as resource reuse and environmental protection. In addition, natural rubber, fluoro rubber, styrene butadiene rubber, polyisoprene rubber, polybutadiene rubber, nitrile rubber, chloroprene rubber, butyl rubber, urethane rubber, silicone rubber, acrylic rubber, epichlorohydrin rubber, ethylene propylene rubber, etc. can be used. It is. Further, the present invention should not be construed as being limited to the rubber material described above, and other elastic materials, for example, a well-known soft synthetic resin material may be used. Then, by selecting a desired elastic material from these materials according to the use environment, the purpose of use, and the use of the elastic laying body (rectangular elastic mat) 2, the elasticity is enhanced and the mechanical properties are enhanced. An elastic laying body (rectangular elastic mat) 2 having excellent (durability) and electrical properties (insulating properties) can be formed.

First, as shown in FIG. 1B, a main body laying die 10 is prepared, and an elastic material 16 for molding the base portion 4 a of the laying main body 4 is put into the main body laying die 10. . The elastic material 16 has a fine small-piece shape, and is subjected to press vulcanization while a large number of small-piece-shaped elastic materials 16 are placed in the main body laying mold 10. As a result, as shown in FIG. 1C, a base portion 4a having a predetermined thickness is formed on the bottom of the main body laying die 10. Since the thickness of the base portion 4a is arbitrarily set according to the purpose and application, the thickness is not particularly limited. In this case, it is preferable to use a relatively hard material for the small piece-shaped elastic material 16 for forming the base portion 4a in consideration of reinforcement of the elastic laying body (rectangular elastic mat) 2. Further, since the base portion 4a has a small portion exposed to the outside, the color of the coloring agent filled in the small piece elastic material 16 is not particularly limited, and an arbitrary color can be selected. In some cases, the colorant need not necessarily be filled.

Next, as shown in FIG. 1 (d), one laying die 12 for the heart-shaped component and four laying dies for the star-shaped component are placed on the laying die 10 for the main body on which the base portion 4 a is formed. Set the mold 14. Then, a desired elastic material is put into each of the laying dies 12 for the heart-shaped component and the laying dies 14 for the star-shaped component. For example, an elastic material 18 filled with a red coloring agent is placed in the laying mold 12 for the heart-shaped component, and an elastic material 20 filled with a blue coloring agent is placed in the laying die 14 for the star-shaped component. . In this state, press vulcanization is performed. After removing the laying molds 12 for the heart-shaped components and the laying dies 14 for the star-shaped components, the elastic material 22 for forming the main body portion 4b of the laying main body 4 is put into the laying dies 10 for the main body. It is preferable that the elastic material 22 of the main body 4b is filled with a coloring agent having a hue that makes the red and blue colors stand out. In this state, by performing the press vulcanization again, the heart-shaped and star-shaped components 6, 8 are integrally formed on the main body 4b. Thereafter, the main body laying mold 10 is removed.

Even in such a process, each of the elastic materials 18, 20, 22 is in the form of a fine small piece, and a large number of small elastic materials 18, 20, 22 are formed into the corresponding molds 12, 14, 10, respectively. Press vulcanization is carried out in the state of being put in the container. As a result, as shown in FIG. 1A, the design in which the blue star-shaped component 8 is arranged around the red heart-shaped component 6 is expressed in the elastic laid member (rectangular elastic mat) 2. You.

Hereinafter, effects of the present embodiment will be described. First, as a first effect, according to the present embodiment, at the time of press vulcanization of small piece-shaped elastic materials 16, 18, 20, and 22, these small piece-shaped elastic materials adhere to each other via an adhesive. Thereby, an elastic laying body (rectangular elastic mat) 2 in which the laying main body 4 (the base portion 4a, the main body portion 4b) and the components (the heart-shaped component 6, the star-shaped component 8) are integrally formed is realized. can do. As a result, it is possible to express a design rich in color change by combining the heart-shaped component 6 and the star-shaped component 8 (beautification of the environment), and at the same time, an elastic laying member (excellent in durability and safety). (A rectangular elastic mat) 2 can be realized. In the above description, a design based on a combination of the heart-shaped component 6 and the star-shaped component 8 has been described. However, it is also possible to express desired patterns, numbers, characters, etc. by arbitrarily changing the shape of the component. It is possible. Therefore, according to the present embodiment, desired environmental beautification can be achieved according to the use environment, use purpose, and use, and at the same time, the elastic characteristics of the elastic laying body 2 allow for safety measures, fall and fall, and the like. Danger prevention can be ensured.

Here, a specific example of the first effect will be described. For example, as shown in FIG. 2, a plurality of elastic laying bodies (rectangular elastic mats) 2 are spread under play equipment (for example, swings) 24 installed in a park or a kindergarten, and the plurality of elastic laying bodies are arranged. It is assumed that one design is expressed over the entire surface of No. 2. In FIG. 2, one large heart-shaped design is represented by combining the partially molded components 6 with the plurality of elastic laying members 2, and a plurality of star-shaped designs are surrounded by the plurality of components 8. Is expressed. Considering this from the point of environmental beautification that meets needs (use environment, etc.), for example, by expressing various designs such as a plurality of star shapes and heart shapes, environmental beautification that matches the environment in which the playground equipment 24 is installed Thus, it is possible to improve the beauty of the periphery of the play equipment 24. On the other hand, considering the safety measures and the prevention of danger due to falling or falling, etc., the elastic laying body 2 has an appropriate shock absorbing property due to its elasticity, and a play equipment user (for example, an infant) accidentally falls. Even if it falls, the elastic laying body 2 functions as a shock absorber. For this reason, safety during use of the playground equipment 24 and prevention of danger due to falling or falling can be surely achieved. In this case, it is preferable to set the elastic laying body 2 on the saddle portion 26 of the playground equipment 24, for example. Thus, the saddle portion 26 can be beautified and have a function as an anti-slip at the same time. It is also preferable to set the elastic laying body 2 on the support 28 of the play equipment 24. As a result, the safety of the playground equipment user in the event of accidentally hitting the support 28 can be ensured.

As a second effect, according to the present embodiment, the components 6, 8 expressing desired patterns, numbers, characters, and designs are simultaneously and collectively formed during the manufacturing process of the elastic laid member 2. Can be molded. For this reason, there is no need for a process in which a desired pattern, number, character, or design is separately overcoated on the surface after the elastic laying body is laid as in the related art. As a result, the time and labor required to complete the product can be greatly reduced, and the manufacturing cost can be reduced.

As a third effect, according to the present embodiment, the elastic laying body 2 in which the laying main body 4 and the structural bodies 6 and 8 are firmly joined (fixed) to each other can be integrally formed. In this case, the patterns, figures, characters, and designs represented by the structures 6, 8 are more resistant to impact, abrasion, heat, cold, and oil than those conventionally coated only. It is excellent in water resistance, water resistance and ozone resistance. Therefore, it is possible to avoid all the conventional problems such as easy peeling and abrasion due to fatigue and aging due to long-term use.

As a fourth effect, according to the present embodiment, the elastic laying body 2 in which the components 6, 8 are integrally formed on the laying main body 4 by press vulcanization can be realized easily and in a short time. Can be. For example, when a certain laying area is set (for example, a playground equipment peripheral area), in the conventional technology, a rubber material is poured and solidified so that characters, designs, and the like are expressed along the laying area. The process must be repeated sequentially, which not only takes a lot of trouble and time, but also increases the manufacturing cost. However, in the present embodiment, the characters and designs of the entire laying area can be expressed simply and in a short time only by laying down the elastic laying body 2 in which the components 6 and 8 are integrally formed. As a result, manufacturing costs can be significantly reduced. Further, when a maintenance (for example, change or correction) of a character design or the like is requested, it is difficult to correct only the maintenance part in the related art, and after removing the rubber material solidified over the entire periphery thereof, The process of pouring and hardening the rubber material from the beginning is repeated again. As a result, it is not possible to quickly respond to maintenance requests, and maintenance costs increase. However, in the present embodiment, it is possible to partially correct only a portion where a maintenance request is made, so that it is possible to quickly respond to the maintenance request, and to make a partial correction. Can be reduced.

Here, specific examples of the second to fourth effects will be described. For example, as shown in FIG. 3, it is assumed that a tennis court is formed by laying a plurality of elastic laying bodies 2 together. In the figure, a plurality of elastic laying bodies 2 are each formed with a structure 32 representing a part of the play line 30, and by combining these plurality of structures 32, one play according to a standard is formed. Line 30 is represented. Considering this from the point of the second effect, the structure 32 representing a part of the play line 30 is formed simultaneously and collectively during the manufacturing process of the elastic laying body 2, and only by laying it, it conforms to the standard. The play line 30 can be constructed easily and inexpensively in a short time as compared with the conventional art. Next, considering the third effect, since the conventional play line 30 is formed of a thinly applied white paint, it is easily peeled and worn due to fatigue and aging due to long-term use. However, by forming the structure 32 expressing the play line 30 integrally with the elastic laying body 2 (laying main body 4), the shock resistance, abrasion resistance, heat resistance, cold resistance, and oil resistance that can withstand long-term use can be obtained. Water resistance, ozone resistance are realized. Considering the fourth effect, a tennis court (play line 30) as specified can be realized simply and in a short time only by laying a plurality of elastic laying bodies 2 at a large cost. Reduction is possible. In addition, even when a part of the play line 30 is lost, only the elastic laying body 2 (elastic laying body indicated by reference numeral 2a in the figure) needs to be replaced. A significant reduction is possible.

Finally, as a fifth effect, according to the present embodiment, the elastic laying body 2 in which the components 6, 8 are integrally formed on the laying main body 4 by press vulcanization treatment has at least impact resistance, It has abrasion resistance, heat resistance, cold resistance, oil resistance, water resistance, and ozone resistance, and also has water permeability. To explain concretely the water permeability, as shown in FIG. 4, a large number of gaps S are randomly formed between the small piece-shaped elastic materials 16, 18, 20, and 22 of the press-cured elastic laid body 2. Therefore, for example, a liquid (for example, water or oil) interposed on the surface of the elastic laying body 2 flows out through the gap S. For this reason, the surface of the elastic laid body 2 can be constantly maintained in a draining state (substantially dry state). The figure shows a state in which the small piece-shaped elastic materials 16, 18, 20, and 22 are joined (fixed) in a regular arrangement, but this is merely an example of the arrangement of the small piece-shaped elastic materials. This is an example for facilitation, and it goes without saying that such a regular arrangement is rare in actual press vulcanization.

Here, a specific example of the fifth effect will be described. For example, as shown in FIG. 5, it is assumed that a single elastic laid body 2 is used as an underlay of a flowerpot 34, and a star-shaped component 8 is designed to surround the flowerpot 34 in this elastic laid body 2. ing. Although it is necessary to water the flowerpot 34 at a certain timing, the excess water usually tends to accumulate at the bottom of the flowerpot 34 and its surroundings. Excess water is not very good for planting and needs to be removed as soon as possible. Even in such a case, the water applied to the flower pot 34 flows outside through the base portion 4a or the main body portion 4b of the elastic laying body 2 (for example, flows out as indicated by an arrow W). In such a case, it is possible to always keep the optimum moisture. In addition, by designing the star-shaped component 8 so as to surround the flowerpot 34, it is possible to simultaneously achieve environmental beautification (improvement of aesthetic appearance). Further, in the tennis court (see FIG. 3) on which the elastic laying body 2 excellent in water drainage property is laid as described above, the surface of the court can always be maintained in a substantially dry state with excellent grip even in rainy weather. As a result, the player is free from anxiety that the player slips or falls accidentally during the play, so that the player can concentrate on the tennis play with confidence. The above-described embodiment is an example, and does not limit the technical scope of the present invention in any way. Needless to say, the following changes are possible. In the embodiment described above, the elastic laying body 2 (laying main body 4) is composed of the base portion 4a and the main body portion 4b. However, the base portion 4a is not necessarily required, and the strength of the elastic laying body 2 (laying main body 4) is not limited. If (durability) and flexibility (flexibility) can be ensured in an optimal state, the elastic laying body 2 may be constituted only by the main body 4b as shown in FIG. 6 (a). In this case, the concave grooves 6a, 8a are formed on the outer periphery of the components 6, 8 during the manufacturing process as described above in order to prevent the components 6, 8 from dropping or falling out of the main body 4b. Is preferred. In this way, the elastic material 22 (see FIGS. 1D and 4) enters each of the concave grooves 6a and 8a at the stage of forming the main body 4b, so that the components 6, 8 and the main body 4b are connected to each other. The two mesh with each other via the concave grooves 6a and 8a. As a result, the components 6, 8 are firmly integrated with the main body 4b without dropping or falling out. Further, in the above-described embodiment, a rectangular elastic mat 2 is assumed as the elastic laying body 2, but the present invention is not limited to this. For example, a use environment such as a circular shape, an elliptical shape, a trapezoidal shape, and a spherical shape is used. Arbitrary shapes can be selected according to the place of use, application, etc. Furthermore, the specifications of the elastic laying body 2 are not limited to mats, but may be widely applied to, for example, handrails and stairs in hospital passageways, sidewalks and guideways in children's parks and kindergartens, and tracks in athletics stadiums. As a result, safety measures, prevention of danger due to falling or falling, etc., and environmental beautification that meets needs can be achieved at the same time. That is, since the elastic laid body 2 of the present embodiment is excellent in elasticity, flexibility, and flexibility, it can be laid along the undulating shape or the uneven shape of the place of use. Further, it goes without saying that the elastic laid body 2 of the present embodiment can be dealt with alone (see FIG. 5) or as a set of a plurality of sheets (see FIGS. 2 and 3).
