Abstract
A body massager includes a casing having handles at opposite sides disposed in planes mutually at right angles, for ease of manipulation of the massager. A massage head is mounted in the casing for pivotal rocking movement about a transverse axis and has a contoured massage surface for imparting a percussive massage action to a patient. The massage head is driven from an electric motor by a dynamically balanced eccentric driving a connecting rod connected to the massage head by way of a resilient link that can be adjusted to vary the amplitude of the rocking motion.
Claims10
A body massager comprising:
- a base structure including a casing having handles for manipulating the massager;
- a drive unit carried by said base structure;
- a massage head having an external massage surface contoured symmetrically about a transverse centre line for percussive massage of the body, the massage head being coupled to the base structure for pivotal rocking movement about an axis parallel to said transverse centre line;
- and,
- means coupling said drive unit with said massage head to reciprocate said massage head in a direction generally normal to said axis at a position spaced from said centre line, for producing said rocking movement of the head;
- wherein two said handles are provided and are disposed one at each side of the casing generally at opposite ends of said axis, each said handle comprising a generally U-shaped formation extending outwardly of the casing with one handle disposed generally parallel to a general plane containing the massage head and the other handle at right angles to said plane.
A body massager comprising:
- a base structure including a casing having handles for manipulating the massager;
- a drive unit carried by said base structure and comprising an electric motor having a driven rotary output shaft;
- a massage head having an external massage surface contoured symmetrically about a transverse centre line for percussive massage of the body, the massage head being coupled to the base structure for pivotal rocking movement about an axis parallel to said transverse centre line;
- and,
- means coupling said drive unit with said massage head to reciprocate said massage head in a direction generally normal to said axis at a position spaced from said centre line, for producing said rocking movement of the head, said means including:
- an eccentric carried by said output shaft;
- a connecting rod extending between the eccentric and said massage head at said position spaced from the centre line of said massage surface for converting rotary motion of said output shaft into reciprocatory motion of the massage head at said position;
- a resilient link which is alternately compressed and relaxed during said reciprocation and which comprises a resilient bushing carried by said connecting rod;
- and adjustable means constraining said link to limit the extent of said compression and relaxation at each reciprocation, and thereby control the amplitude of said pivotal rocking movement of the massage head, said adjustable means comprising a seat on the massage head and a lever carried by said head, the bushing being constrained between the lever and seat, and the lever being adjustable to vary the constraint applied to the bushing.
