Abstract:
A finger pressure device comprising:at least two spherical bodies, each formed by first and second semi-spherical bodies,said first semi-spherical body including:a first outer surface,a first inner surface,a plurality of first protuberances on the first outer surface,a first bore extending therethrough,a concavity at the first inner surface, andan annular groove in the first inner surface between the first outer surface and the concavity;said second semi-spherical body including:a second outer surface,a second inner surface,a plurality of second protuberances on the second outer surface,a second bore extending therethrough,a convexity at the second inner surface for mating with the concavity of the first semi-spherical body, andan annular groove in the second inner surface between said second outer surface and the convexity;a bolt arrangement extending through the bores of said first and second semi-spherical bodies for securing said first and second semi-spherical bodies together;an annular rim associated with each said spherical body, each said annular rim positioned between the first and second semi-spherical bodies of the respective spherical body, each said annular rim including:a rim outer surface,a rim inner surface,a plurality of rim protuberances on the rim outer surface,a projection on the rim inner surface, anda first radial gap which defines first and second opposing surfaces;at least one coupling rod, each for connecting together two of said spherical bodies, each said coupling rod including:a central rod extending through radial gaps of the annular rims of first and second ones of said spherical bodies, andfirst and second spherical protuberances on opposite ends of said central rod, said first spherical protuberance inserted into the annular grooves of the first and second semi-spherical bodies of the first one of said spherical bodies and said second spherical protuberance inserted into the annular grooves of the first and second semi-spherical bodies of the second one of said spherical bodies; andcaps covering the bores at the outer surfaces of the part-spherical bodies after the first and second semi-spherical bodies of each spherical body have been secured together by said bolt arrangement.
