  • Patent number: 11118367
    Abstract: The invention relates to a device for enhancing swimming pools by creating a bubbling and/or sparkling effect on a given surface. The invention relates to a device in the form of a mat for creating a diffusion of air bubbles rising on all or part of the surface of a swimming pool, making it possible to enhance an already-built swimming pool in a simple manner by adding bubbling and/or sparkling water effects. The device is made up of four major elements which are the multi-layer mat, of which the upper surface is perforated so as to provide the sought bubbling effect, the perforated edge strip attached to the appropriate side of the mat and to which a distribution cone is linked that, in turn, is connected to an air compressor. When the compressor is started up, the output flow is distributed evenly over the entire surface of the mat. The device according to the invention is especially intended for enhancing all types of swimming pools and leisure pools.

  • Publication number: 20020188237
    Abstract: An air bubble massage bathtub mat system featuring a remote control and a flexible mat is disclosed. The remote control unit communicates with a blower/air heater unit contained in a housing. The housing is connected to the mat by a tube that directs air into the mat. The mat is formed of a flexible polymeric sheet material that may be rolled up for storage. The mat includes a plurality of flexible blocks that are retained between two layers of polymer sheet material that also define the air passages in the mat. Air flows through the mat and exits the mat in small holes that provide small air bubbles to water contained in a bathtub. Suction cups attached to elongated strips which are held to the mat by elongated pockets hold the mat stationary in the bathtub.
