Title:
流体収容容器のライナ上下システム
Document Type and Number:
Japanese Patent JP3672322
Kind Code:
B2
Abstract:
A system (10) for raising and lowering a swimming pool liner (12) includes a plate (22) used to define a spill way (24) for providing fluid communication between an outside surface of the liner and an inside surface (16) of the pool (14). The liner is detached from the surface of the pool in the region behind the plate and reattached along an upper edge (28) of the plate. Conduit (30), having length (30'), extends along back face (32) of plate (22) and below the upper edge (28). Holes (34) cut in the plate provide communication with length (30'). Conduit (36) extends across the back face (32) near its lower edge (38) to provide air to the spill way (24). The length (36') of conduit (36) is provided with a number of holes (40) for admitting air into the spill way. In order to lift the liner, air is directed through conduit (30) to the outside surface (26) of the liner. The air lifts the liner up and away from the inside surface (16) displacing water held within the pool to flow over upper edge (28) into the spill way so that the water now lies beneath the outside surface.
