PLAY FACILITIES MADE OF POLYURETHANE FOAM

摘要

PROBLEM TO BE SOLVED: To provide play equipment made of polyurethane foam which has widely reduced possibility of falling down than conventional ones even jumping down on or stepping on the equipment, large effect for rehabilitation, and is interesting as a play equipment because the equipment gradually recovers an original shape even compressed smaller. SOLUTION: This play equipment is formed of polyurethane foam with 50-160 kg/m<3> of density, the original shape restorable minimum compressed thickness as small as 1/15-1/5, and 5-100 seconds of time to restore original height upon compressing 10 cm thick foam to 1/10 and releasing the compression force.
