Pneumatic powered lift for swimming pools

Abstract

A lift facilitates ingress and egress of handicapped people, including a platform support above water level providing an essentially flat and horizontal surface on which the person can stand or sit on a wheelchair. This platform is connected to propellant resources to move vertically to submerge and emerge from pool water. The propellant resource attached to the receiving platform includes pneumatic cylinders forming the upper section of the respective vertical tubular center posts extending from the swimming pool floor and rise adjacent the swimming pool wall. The piston of each cylinder is linked to a respective longitudinal piston rod projected downwards along the cylindrical body of each center post, until its free lower end attaches to the structure that supports the receiving platform, projecting transversely outside the columns, through two vertical guide slots extending from an intermediate point of the columns down to the lower extreme immersed in the water.

1 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, created to facilitate the ingress and egress of handicapped people, which includes a platform support designed to be secured above the water level, preferably coplanar to the pool's edge providing an essentially flat and horizontal surface on which the person might stand or remain on a chair, this platform is connected to propellant resources so that it may perform vertical movements to submerge and emerge from the water in the swimming pool, characterized in that the propellant resource attached to the receiving platform includes a pair of pneumatic cylinders placed in the upper section of the respective vertical tubular center posts that extend from the swimming pool floor and rise adjacent to the swimming pool wall; the piston of each pneumatic cylinder is connected to a respective vertically elongated piston rod projected downwards along the interior of the cylindrical body of each center post, until its free lower end is attached to the structure supporting the receiving platform, which is projected transversally to the outside of the columns, through the corresponding vertical guide slots that extend from an intermediate point of the mentioned columns to the lower end immersed in the water. 
     
     
         2 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, according to  claim 1 , characterized in that the structure that supports the receiving platform is connected to the elongated piston rod that is projected from the piston of each pneumatic cylinder through two metal plates that jut out through the vertical slot in each center post. 
     
     
         3 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, according to  claim 1 , characterized in that the upper section of the vertical tubular centre posts where the pneumatic cylinders are formed extends between the free end of the said center post up to an intermediate point that determines the beginning of the vertical guide slots above the floor level. 
     
     
         4 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, according to  claim 1 , characterized in that each pneumatic cylinder is connected to a pressure driven incoming and outcoming fluid circuit originated in a pneumatic compressor, with the insertion of the corresponding valves at intervals placed in the control board accessibly located for the user. 
     
     
         5 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, according to  claim 1 , characterized in that each vertical center post is attached to a corresponding fixed handrail which is installed on the floor, adjacent to the swimming pool's edge. 
     
     
         6 . PNEUMATIC POWERED LIFT FOR SWIMMING POOLS, according to  claim 1 , characterized in that the structure supporting the receiving platform bears a pair of lateral fixed handrails that are part of the mentioned structure.
