Abstract

A massage device for the soles of the feet is provided. The device includes a number of units releasably connected together to form a long track which allows people to walk thereon and have the soles of their feet massaged by pebble-like projections formed on each of the units. Each unit includes a rectangular, flat, hollow body defining a sealed interior space inflated by air. The flat body has an upper surface having a plurality of different-sized pebble-like projections distributed uniformly thereon. The hollow body is preferably made of a resilient and slightly inflatable material so that by being inflated, the interior pressure is adjusted to provide an adjustable rigidity of the body. With the resilience and the adjustable rigidity provided by the interior pressure, the pebble-like projections are allowed to deflect and deform when stepped on by people, to comply with the shape of the soles of the feet, so as to avoid damaging the soles. Bosses and holes are provided on respective edges of the flat hollow body to allow one unit to be connected to another by having the bosses of one received and engaged by the holes of the other.

A massage device for the soles of the feet comprising a plurality of massage units releasably coupled one to another to form a track upon which a user walks, each of said plurality of massage units including:

a hollow body formed of a resilient air impervious material and having an upper surface for supporting a user's feet, said hollow body having a single air filled enclosed interior cavity for establishing a predetermined rigidity of said upper surface;
a plurality of first projections formed in a uniform distribution on said upper surface of said hollow body, each of said plurality of first projections being formed of a solid material composition having a pebble-like contour, each of said plurality of first projections extending a first predetermined height from said upper surface;
a plurality of second projections formed in a uniform distribution on said upper surface of said hollow body in alternating relation with respect to said plurality of first projections, each of said plurality of second projections being formed of a solid material composition having a pebble-like contour, each of said plurality of second projections extending a second predetermined height from said upper surface, said second predetermined height being greater than said first predetermined height;
and,
means for releasably coupling one of said plurality of massage units to another of said plurality of massage units;
said releasable coupling means includes a plurality of first side flange members extending from at least one side of said hollow body and a plurality of second side flange members extending from an opposing side relative to said at least one side of said hollow body, each of said plurality of first side flange members having a boss extending from a lower surface thereof, each of said plurality of second side flange members having a through opening formed therein for receipt of a respective boss of a first side flange member of another of said plurality of message units.
