Massage device and method of use
First Claim
1. A massage device comprising,a housing,an electrical input,a motor,a switch in electrical communication with the electrical input and the motor, the switch configured to selectively provide power from the electrical input to the motor,an actuated output operatively connected to the motor and configured to reciprocate in response to activation of the motor,a treatment structure operatively connected to a distal end of the actuated output,wherein the actuated output is configured to reciprocate the treatment structure at a frequency of between 15 Hz and 100 Hz, and at an amplitude of between 0.15 and 1.0 inches, and wherein the combination of amplitude and frequency provides efficient reciprocation of the treatment structure such that the treatment structure provides therapeutically beneficial treatment to a targeted muscle of a user,wherein the motor is configured to rotate a shaft having a shaft gear thereon about a shaft rotation axis, wherein the housing includes a gear member disposed therein that is operatively engaged with the shaft gear and rotates about a gear rotation axis, wherein the actuated output is operatively connected to the gear member, wherein rotational motion of the shaft is converted to reciprocating motion of the actuated output through the engagement of the shaft gear and the gear member, wherein an eccentric interface is disposed on the gear member at a location other than the gear rotation axis, anda reciprocator shaft operatively connected to the eccentric interface, and a containment member, wherein a head of the reciprocator shaft is contained by the containment member to restrict motion of the reciprocator shaft to a linear motion that is perpendicular to the gear rotation axis, wherein the containment member defines a reciprocation space in which the head of the reciprocator shaft can reciprocate, wherein the containment member includes legs that extend toward the gear member and at least partially define the reciprocation space, and wherein each leg defines a step on an inside surface thereof.

Abstract
A massage device that includes a housing, an electrical input, a motor, a switch in electrical communication with the electrical input and the motor and configured to selectively provide power from the electrical input to the motor, an actuated output operatively connected to the motor and configured to reciprocate in response to activation of the motor, and a treatment structure operatively connected to a distal end of the actuated output. The actuated output is configured to reciprocate the treatment structure at a frequency of between about 15 Hz and about 100 Hz, and at an amplitude of between about 0.15 and about 1.0 inches. The combination of amplitude and frequency provides efficient reciprocation of the treatment structure such that the treatment structure provides therapeutically beneficial treatment to a targeted muscle of a user.
