<p>PROBLEM TO BE SOLVED: To minimize the dropping distance of a dropping article by disposing curing net parts retractable into an elevator shaft, and mounting a guide member on an elevator car so as to retract the curing net part with the elevating movement of the elevator car for disposing the curing net parts of a plurality of stages. SOLUTION: Curing net parts 1 are disposed inside an elevator shaft at an arbitrary interval, for example, each three layers. When an elevator car A is elevated inside the elevator shaft, the curing net parts 1 positioned above and below it rotate around a shaft 3 which is fixed on a supporting structure 2 with the respective guide plates 10a, 10b and extends in the horizontal direction, and retracts from the course of the elevator car A. When the elevator car passes, the curring net part 1 returns to its original horizontal condition by the spring force of respective springs. At this time, the curing net part 1 rotates rapidly, however, a cushioning member 12 is disposed at the supporting structure 2, thus it is possible to relieve impact.</p> |
