SWIMMING POOL Russian patent published in 2009 - IPC E04H4/16 

FIELD: construction.

SUBSTANCE: invention is related to construction of swimming pools of individual and public use. Swimming pool comprises leak-tight shell, overflow chute arranged along its perimetre, overflow rag floating on water surface, which interacts with side of inclined grids inverted to overflow chute, and filtering material with low hydraulic resistance. Overflow chute is made in the form of additional board from profile with angular cross section. Horizontal shelf of chute that creates bottom is fixed to provide for leak-tightness to pool board. Vertical shelf that creates back side of chute is equipped with end shelf that is bent outside, to which frame is fixed hanging over horizontal shelf with detachable overflow grids. Front wall of overflow chute creates a profile laid along edge of horizontal shelf through drain pad of corrugated sheet with three shelves in cross section. Lower and upper horizontal shelves and downward inclined shelf arranged in between create a longitudinal wedge-like belt with top inverted to pool reservoir, and arranged at the level of grooves between waves that dash against board in process of pool use. Internal cavity between lower and upper shelves of profile is filled with porous filtering material arranged along bottom of overflow chute, for instance in the form of polyurethane foam blocks, which are laid tight to each other, to back wall of overflow chute and profile shelves. Internal edge of overflow rag is laid onto upper shelf of profile and pressed from top with shelf bent inside from protective-decorative grid. Lower longitudinal edges of inclined grids arranged into overflow chute with overflow grids removed, are laid under bent bulges of protective-decorative grids. Upper longitudinal edges of inclined grids are laid onto inclined shelves of planks installed along end shelf of overflow chute back shelf, and pressed from top with overflow grids. On lower shelf in profile part that protrudes to zone of pool reservoir there is at least one electric pump of submersible type. Suction nozzle of electric pump is connected via opening with internal cavity of wedge-like part, and injection nozzle sends cleaned water directly into pool reservoir.

EFFECT: invention makes it possible to reduce losses of pool water surface area and to simplify access to filtering material.
