1. A percussive massager comprising:

  • a housing having two transversely spaced apart apertures formed therein;

    a motor transversely mounted within the housing, the motor having a rotary output shaft with opposed ends protruding from opposite ends of the motor;

    a pair of connecting rods each having a first end and a second end, wherein the first ends of the connecting rods are rotatably connected to the opposed ends of the output shaft at locations eccentrically spaced about the axis of rotation of the output shaft to cause the second ends of the connecting rods to reciprocate in an asynchronous manner as the output shaft rotates;

    an elongated rocker arm having a central pivot axis, wherein the rocker arm is pivotably mounted relative to the housing and includes a pair of transversely spaced apart end portions each operably connected to the second ends of the connecting rods, causing the rocker arm to rock about the central pivot axis as the connecting rod second ends reciprocate;

    two transversely spaced apart massage nodes which at least partially project from the housing through the apertures, each massage node operably connected to one of the spaced apart end portions of the rocker arm and associated connecting rod second end;

    a pair of flexible annular sleeves mounted to the housing and generally sealing the apertures, each sleeve having a central opening sized to enable a connector to pass therethrough for mounting the massage node; and

    a mounting plate for mounting the annular sleeves to the housing, wherein the massage nodes move asynchronously toward and away from the housing providing a percussive massage effect in response to rotation of the output shaft.
