Abstract
Abstract A massaging machine promotes circulation in the lower extremities of the body of a user. It comprises massaging components formed as a pair of hollow semi-cylindrical concave dishes, which are driven by an electric motor in pivotal and oscillatory motion relative to a fixed base frame. A mounting plate is displaceable relative to the base frame and can be set in horizontal oscillations by way of a motor-driven single cam and return spring component moving along the longitudinal axis of the massaging components. An arcuate array of cylindrical bearings support each massage component, which in turn is rigidly attached to a lever arm protruding downwards. The lever arms are set in motion to carry out oscillations by way of a motor-driven double cam via rods and return springs. By way of this mechanical arrangement the massaging operation in two directions at once is achieved as in the case of manual massage. Specifically, the massaging is effected perpendicular to the axis of the legs in a radial and oscillating motion and longitudinal to the axis of the legs in a forward and backward motion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
Apparatus for massaging the legs of a user, comprising a pair of arcuate massage components, each of said pair being formed as an axial section of an open-ended cylinder and having a concave surface adapted to receive a leg of a user and an oppositely disposed convex surface facing inwardly of said apparatus, a casing, a lever integrally mounted on said convex surface of each of said pair of massage components and having an end extending into said casing, first cam means adapted to act on said lever ends for displacing said levers along and opposite a first direction substantially perpendicular to the extent of said levers, motor means for driving said first cam means, and an arcuate array of cylindrical bearings individual to each of said pair of massage components and mounted on said casing, each said array of cylindrical bearings extending parallel to the axis of and contacting said convex surface of its corresponding massage component, whereby displacement of said levers along and opposite said first direction is translated into pivotal displacement of said pair of massage components about their respective axes.
Claim 2
Dependent Claim
184 words
Apparatus for massaging the legs of a user, comprising a pair of arcuate massage components, each of said pair being formed as an axial section of an open-ended cylinder and having a concave surface adapted to receive a leg of a user and an oppositely disposed convex surface facing inwardly of said apparatus, a casing, a lever integrally mounted on said convex surface of each of said pair of massage components and having an end extending into said casing, first cam means adapted to act on said lever ends for displacing said levers along and opposite a first direction substantially perpendicular to the extent of said levers, motor means for driving said first cam means, and an arcuate array of cylindrical bearings individual to each of said pair of massage components and mounted on said casing, each said array of cylindrical bearings extending parallel to the axis of and contacting said convex surface of its corresponding massage component, whereby displacement of said levers along and opposite said first direction is translated into pivotal displacement of said pair of massage components about their respective axes.
Claim 3
Dependent Claim
50 words
Apparatus according to claim 1, wherein said casing comprises a mounting plate on which said arcuate arrays of cylindrical bearings are mounted, and second cam means adapted to act on said mounting plate for displacing said mounting plate along and opposite a second direction substantially perpendicular to said first direction.
Claim 4
Dependent Claim
31 words
Apparatus according to claim 2, wherein said first and second cam means comprise associated spring means for urging said levers and said mounting plate opposite said first and second directions, respectively.
Claim 5
Dependent Claim
70 words
Apparatus according to claim 2, wherein said mounting plate is divided in two sections, one section individual to each of said pair of massage components, said second cam means comprising a cam element individual to each of said two sections, each said cam element being limited to a range of movement of 180°, whereby said second cam means act as an oscillating damper for said mounting plate within said casing.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 1, wherein each of said pair of massage components comprises a plurality of flexible finger elements extending from said concave surface, said finger elements having slightly conical projections with rounded tops.
