Abstract
The drain apparatus of the present invention is designed and configured to prevent the entrapment of a person by the suction or vacuum forces of a drain in a swimming pool, spa, or any other large body of water with a recirculation system. The drain apparatus of the present invention has a spring biased plunger that immediately closes the drain of a swimming pool, spa, or any other large body of water when a substantial portion of the drain cover is blocked or restricted. By closing the drain, the drain apparatus of the present invention eliminates any vacuum or suction pressure at or underneath the drain cover that entraps a person thus allowing the person to break free easily and immediately without any time delays.
Claims26
A drain apparatus for installation in a swimming pool, a spa, or any large container of water comprising:
- a drain orifice that is in fluid communication with a suction pump for draining water from said swimming pool, spa, or any large container of water;
- a drain cover immovably secured adjacent a surface of said swimming pool, spa, or any large container of water so as to prevent any vertical displacement of said drain cover and having a plurality of drain openings through which water from said swimming pool, spa, or any large container of water is drained by said suction pump;
- sealing means slidably attached to said drain cover for opening said drain orifice when said sealing means is disposed in a top position and closing said drain orifice when said sealing means is disposed in a bottom position, such that a vacuum underneath said drain cover is eliminated when said sealing means is in said bottom position;
- and
- means for biasing said sealing means toward said top position such that said drain orifice is normally open, but when a maximum allowed vacuum level is exceeded, said biasing means enables said sealing means to slide toward said bottom position without any vertical displacement of said drain cover.
A drain apparatus for installation in a swimming pool, a spa, or any large container of water comprising:
- a mounting plate having a drain orifice that is in fluid communication with a suction pump for draining water from said swimming pool, spa, or any large container of water;
- means for securing said mounting plate adjacent a surface of said swimming pool, spa, or any large container of water;
- a drain cover having a bottom face and a plurality of drain openings through which water from said swimming pool, spa, or any large container of water is drained by said suction pump;
- means for immovably securing said drain cover to said mounting plate so as to prevent any vertical displacement of said drain cover;
- a plunger slidably attached to said bottom face of said drain cover in a top position to maintain said drain orifice of said mounting plate open and closing said drain orifice of said mounting plate when said plunger is disposed in a bottom position, such that a vacuum underneath said drain cover is eliminated when said plunger is in said bottom position;
- and
- means for biasing said plunger toward said top position such that said drain orifice of said mounting plate is normally open, but when a maximum allowed vacuum level is exceeded, said biasing means enables said plunger to slide toward said bottom position without any vertical displacement of said drain cover.
A drain apparatus for installation in a swimming pool, a spa, or any large container of water comprising:
- a drain orifice in a surface of said swimming pool, spa, or any large container of water that is in fluid communication with a suction pump for draining water from said swimming pool, spa, or any large container of water;
- a drain cover having a plurality of drain openings through which water from said swimming pool, spa, or any large container of water is drained by said suction pump;
- means for immovably securing said drain cover over said drain orifice and adjacent said surface of said swimming pool, spa, or any large container of water so as to prevent any vertical displacement of said drain cover;
- a plunger slidably attached to said drain cover in a top position to maintain said drain orifice open and closing said drain orifice when said plunger is disposed in a bottom position, such that a vacuum underneath said drain cover is eliminated when said plunger is in said bottom position;
- and
- means for biasing said plunger toward said top position such that said drain orifice is normally open, but when a maximum allowed vacuum level is exceeded, said biasing means enables said plunger to slide toward said bottom position without any vertical displacement of said drain cover.
