  • Safety device for swimming pools
    Patent number: 5734999
    Abstract: A safety device comprising a floor drain grate includes at least two separate regions, and preferably three, with openings through which water can flow into a pool drain. The regions are preferably spaced to either side of the pool drain, by a distance which effectively prevents a swimmer from blocking all the openings at once and becoming stuck to the grate by suction. The floor drain grate may be provided as a retrofit to replace an existing drain grate of a pool.
