SWIMMING POOL Russian patent published in 2008 - IPC E04H4/16 

FIELD: construction, particularly swimming pool structure.

SUBSTANCE: swimming pool comprises rectangular or polyhedral sealed body, overflow gutter extending along body perimeter and provided with overflow mat and filtering materials having low flow resistance. Said filtering members may be formed as at least one layer of foamed polyurethane block layer tightly pressed one to another and to overflow gutter walls. Space over overflow mat base creates drain channel. The structure comprises pipeline. Lids closing overflow gutter have V-shaped grids arranged from inner sides thereof. The first grid sides face overflow gutter and are secured along rear lid edge. Other grid sides face swimming pool bowl, are secured along front lid edge and are supported by bent part over front wall of overflow gutter. Front wall of overflow gutter is made as additional gutter installed on overflow gutter bottom and spaced therefrom. The space is created by transversal partitions laid on base thereof and defining through grooves, which connect overflow gutter with swimming pool bowl. Rear wall of additional gutter has inclined flange. Inner edge of floating overflow mat is secured to the flange. The inner edge cooperates with inclined part of V-shaped grid side facing overflow gutter to prevent reverse wave movement inside swimming pool bowl. Front wall of additional gutter has flange bent through right angle and supporting V-shaped grid. Filtering material is arranged inside additional gutter and is spaced from base thereof to create drain channel. The drain channel is connected with socking electric pump pipe through pipeline. Pressure pump pipe is secured to pipeline of flow device, which supplies cleaned water into swimming pool bowl.

EFFECT: provision of necessary water cleaning degree in the case of occasional or casual swimming pool usage, that is in the case of low efficiency of self-cleaning system, which uses wave energy for swimming pool cleaning, elimination of orifices and overflow gutter, which complicate usage of special film for inner waterproofing covering creation.
