Abstract
A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor, and a massage attachment secured to a distal end of the push rod assembly. The reciprocating motion of the push rod assembly has a user-adjustable amplitude.
Claims19
A percussive therapy device comprising:
- a housing,
- an electrical source,
- a motor positioned in the housing,
- a switch for activating the motor,
- a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor,
- a variable amplitude assembly that includes a counterweight that is rotatable about a first axis in a first direction and an opposite second direction, and a movable member that is movable with respect to the counterweight between a first position and a second position, wherein the movable member includes an offset shaft extending therefrom that defines a second axis that is parallel to the first axis, wherein the push rod assembly is operatively connected to the offset shaft, wherein the movable member is movable from the first position to the second position when the rotation of the counterweight is reversed from the first direction to the second direction, wherein the second axis is positioned closer to the first axis when the movable member is in the first position than when the movable member is in the second position, wherein the counterweight defines a length that includes a halfway point, and wherein the first axis is offset from the halfway point, and
- a massage attachment secured to a distal end of the push rod assembly,
- wherein the reciprocating motion of the push rod assembly has a user-adjustable amplitude.

A variable amplitude assembly comprising:
- a counterweight that is rotatable about a first axis in a first direction and an opposite second direction,
- a movable member that is movable with respect to the counterweight between a first position and a second position, wherein the movable member includes an offset shaft extending therefrom that defines a second axis that is parallel to the first axis, wherein the movable member is movable from the first position to the second position when the rotation of the counterweight is reversed from the first direction to the second direction, wherein the second axis is positioned closer to the first axis when the movable member is in the first position than when the movable member is in the second position, and wherein the counterweight defines a length that includes a halfway point, and wherein the first axis is offset from the halfway point.
A variable amplitude assembly comprising:
- a counterweight that is rotatable about a first axis in a first direction and an opposite second direction,
- a movable member that is movable with respect to the counterweight between a first position and a second position, wherein the movable member includes an offset shaft extending therefrom that defines a second axis, wherein the movable member is movable from the first position to the second position when the rotation of the counterweight is reversed from the first direction to the second direction, and wherein the second axis is positioned closer to the first axis when the movable member is in the first position than when the movable member is in the second position, and
- an interference member that is positioned in a channel defined in the counterweight, wherein the interference member is movable between a deployed position and a rest position, wherein in one of the deployed position or the rest position the interference member prevents the movable member from moving between the first position and the second position, and wherein in the other of the deployed position and the rest position the interference member does not prevent the movable member from moving between the first position and the second position, and wherein the interference member is configured to move independently from the movable member.
