Abstract

PURPOSE:To obtain a stable mat, by clamping a rubber substrate having legs on its undersurface and resin fitting sections with through-holes on its surface between molds that have recesses having arbitrary configurations opposite to said fitting sections and said through-holes, and injecting a melted synthetic resin. CONSTITUTION:The substrate 1 of a rubber material has the legs 2 on its undersurface and the fitting sections 3 for turf or the like on its surface, the fitting section 3 is provided with an arbitrary number of the through-holes 5, and the sides of the substrate 1 have joining sections 4a, 4b. The mold that will be fitted with the surface section of the substrate 1 is provided with neidle-leave like recesses 7 opposite to the fitting section 3 and the mold that will be fitted with the back of the substrate 1 is provided with the recesses 9 for the legs at positions opposite to the through-holes 5. After the substrate is vulcanized and molded, it is clamped between the molds 6, 8, and the melted synthetic resin is injection molded through injection ports 10 to obtain a mat or the like. EFFECT:Undulation of the mat or the like would be prevented. USE:Artificial turf, lattice for foodstuffs, door mats, etc. can be produced.

施設上の歩行を困雉にしていた。In recent years, mat sheets such as artificial lawns, food-grade drainboards, and shoe-wiping mats have been manufactured from thermoplastic resins, but synthetic resins have a large expansion and contraction difference due to cold and heat, so the mat material may become wavy or shrink after being installed. Not only did it look bad, but there was also the risk of tripping and falling. In addition, since mats connected by joints are spread over a wide area, in summer there is a significant difference in expansion and contraction between areas exposed to direct sunlight and areas in the shade, resulting in waving, which is a problem that must be considered by creating cracks in the joints. However, this expansion and contraction did not absorb the soles of the sides, causing the joints to come off and causing wide-ranging waves, making it difficult to walk on the facility.

本発明はこのような現状に鑑み案出されたもので、以下
図面にもとづきながら本発明の冥施例について詳述する
。The present invention has been devised in view of the current situation, and embodiments of the present invention will be described in detail below based on the drawings.

, 4b are provided.

６は、前記基板ｌの表面部と嵌合する金型で、針葉形状
等の凹部ツを前記嵌合部Ｓと対向すべく設けている。Reference numeral 6 denotes a mold that fits into the surface portion of the substrate I, and has a concave portion such as a needle leaf shape so as to face the fitting portion S.

８は、前記基板１の裏面部と嵌合する金型で、前記透孔
５と対向する位置に支脚用凹部９を設けている。Reference numeral 8 denotes a mold that fits into the back surface of the substrate 1, and has a supporting leg recess 9 at a position facing the through hole 5.

基板１を加硫成型後、前記金型６．８で挾持したのち、
金型６の注入口１０より溶融した合成樹脂を射出し成形
するものである。After the substrate 1 is vulcanized and molded, it is held between the molds 6.8, and then
Molten synthetic resin is injected and molded through an injection port 10 of a mold 6.

すなわちこのような方法により成型されたマット地にあ
っては基板ｌはゴムを素材としているため殆んど寒暖に
よる伸縮は生じ１ｊいのでジヨイント部に無理が生じ、
外れ易くなったりマット地の波打ち現象を防ぐことがで
きることとなる。In other words, in the matte fabric formed by this method, since the substrate l is made of rubber, it expands and contracts due to temperature and temperature, which causes strain on the joint part.
This will prevent the mat from coming off easily and causing the mat to ripple.

また、基板１はゴムに素材としており、柔軟性があるた
め踏み心地は快適なものとなるが、柔軟すぎるため支脚
のみで維持することは困難となる。Further, the substrate 1 is made of rubber and is flexible, making it comfortable to step on, but it is too flexible and difficult to maintain using only the supporting legs.

孔５より金型８の凹部９に流出し突出部を形成すること

なるので安定性も確保しうるものとなる。Therefore, in the method of the present invention, the injected molten resin flows out from the through hole 5 of the substrate 1 into the recess 9 of the mold 8 and forms a protrusion, and the synthetic resin loses its function as a supporting leg. Stability can also be ensured.
