Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 287 words
A massager comprising: a power supply unit comprising a generally mushroom-shaped buoyant housing having a broad-brimmed upper portion and a relatively narrow downwardly-extending lower portion, a battery box disposed in said relatively narrow downwardly-extending lower portion and a battery disposed in said battery box so that said unit when placed in water will float in an upright position with said relatively narrow downwardly-extending portion below the surface of the water, a mercury switch disposed in said upright position and means for positioning said mercury switch in a position so that the switch is in a closed position when said unit is upright; a vibrator unit comprising a vibrator assembly including two vibrators disposed at right angles against one another and a layer of mattress covering said vibrator assembly, said mattress having a plurality of raised portions on the top for massaging and a plurality of suction discs and hanging means for securing said unit to an object are fixed to said unit; an electric wire electrically connected to said power supply unit and said vibrator unit by said mercury switch, said electric wire connected to the positive pole of said battery unit and to a first contact of said mercury switch and said electric wire connecting the negative pole of said battery to said second contact of said mercury switch so that current will flow from said battery to said vibrator unit when said switch is closed by said unit being in an upright position and will not flow when said switch is open as a result of said unit being tilted, said power supply unit, said vibrator unit and said electric wire being respectively sealed against water so that the massager can be used under water.
