IMPACT-ABSORBING FLOORING
To provide an impact-absorbing flooring that can sufficiently correspond to the risk of femur fracture.SOLUTION: The shock-absorbing flooring 110 has a flooring surface material 111 formed of a hard material and a flooring substrate material 112 formed of a soft material. The flooring surface material 111 has a thickness of 2 to 20 mm, and a value of flexural rigidity of the floor surface material 111 per unit width is 0.01 Nmor more and 100 Nmor less. In a condition set so that a reference impact load Fs, generated by dropping an impactor to apply an impact to a buffer material, becomes 6500 N, an impact load F, generated when the impactor is dropped to apply an impact via the buffer material, becomes 2000 N or more and 5000 N or less.SELECTED DRAWING: Figure 1
【課題】大腿骨骨折のリスクに十分に対応することができる衝撃吸収床材を提供する。【解決手段】硬質性材料からなる床上材１１１と、軟質性材料からなる床下地材１１２とを有し、床上材１１１の厚さが２〜２０ｍｍであると共に、単位幅における床上材１１１の曲げ剛性の値が０．０１Ｎｍ2以上１００Ｎｍ2以下であり、衝撃付与体を落下させて緩衝材へ衝撃を付与したときに生じる基準衝撃荷重Ｆｓが６５００Ｎとなるように設定された条件において、衝撃付与体を落下させて緩衝材を介して衝撃を付与したときに生じる衝撃荷重Ｆが２０００Ｎ以上５０００Ｎ以下となる衝撃吸収床材１１０である。【選択図】図１
