SHOCK ABSORBING FLOOR MATERIAL
To provide a shock absorbing floor material capable of suppressing facture of a thighbone of, for example, the aged or an infant caused by falling and having durability such as static load resistance or dynamic load resistance while exhibiting a soft material absorption effect.SOLUTION: The shock absorbing floor material capable of suppressing facture of a thighbone of a user caused by impact of falling is a floor material 10 and comprises three layers of: a floor upper material 20 made of a hard material; a floor substrate material 30 made of a soft material and provided below the floor upper material 20; and an intermediate material 40 positioned on the midway between the floor upper material 20 and the floor substrate material 30, and flexural rigidity at a unit width of the intermediate material 40 is 10 Nm2-100 Nm2. The thickness of the intermediate material 40 can be 1 mm-5 mm. The intermediate material 40 can be formed by a thermoplastic resin containing an inorganic additive by 20 wt.%-85 wt.%. The inorganic additive contained in the intermediate material 40 can be a calcium silicate or a calcium carbonate.SELECTED DRAWING: Figure 1
【課題】本発明は、例えば高齢者や幼児などの転倒による衝撃で生じる大腿骨の骨折を抑制することができ、軟質材料による吸収効果をもちながらも、耐静荷重性や耐動荷重性といった耐久性も有する衝撃吸収床材を提供できる。【解決手段】使用者の転倒による衝撃で生じる大腿骨の骨折を抑制する衝撃吸収床材であって、硬質性材料からなる床上材２０と、床上材２０の下方に設けられる軟質材料からなる床下地材３０と、床上材２０、床下地材３０との少なくとも中間に位置する中間材４０の３層からなる床材１０であり、中間材４０の単位幅における曲げ剛性が１０Ｎｍ２以上１００Ｎｍ２以下である。また、中間材４０は、厚みが１ｍｍ以上５ｍｍ以下でも良いし、中間材４０は、無機系添加剤２０ｗｔ％～８５ｗｔ％を含む熱可塑性樹脂で構成されても良いし、中間材４０に含有する無機系添加剤がケイ酸カルシウム若しくは炭酸カルシウムでも良い。【選択図】図１
