    Abstract: A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A transfer bracket has a first end portion coupled to the pivot of the crank. A flexible transfer linkage has a first end coupled to a second end portion of the transfer bracket. A piston has a first end coupled to a second end of the transfer linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment.

    Abstract: A system applies compression, vibration and heat to a body part of a person. The system includes a portable vibration and heat generation apparatus having a flexible support platform and a bag-like enclosure extending from the support platform. A cylindrical control unit is mounted to the support platform and extends perpendicularly from the support platform. The control unit has a diameter of between 50 millimeters and 100 millimeters. The control unit houses electronic circuitry and at least one battery. Four vibration pods extend from the support platform into the bag-like structure. The bag-like structure also houses a heat generation unit. The control unit extends through a circular bore in a compression wrap. The compression wrap is securable to a body part with a distal wall of the bag-like enclosure against the body part. The system selectively applies vibration, heat or a combination of vibration and heat to the body part.

    Abstract: A percussive massage device includes a cylinder extending along a longitudinal axis. A motor shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a first pivot offset from the central axis. A pinion gear is coupled to the first pivot. The pinion gear rotates within a ring gear. The pinion gear has a second pivot that rotates about the first pivot. A reciprocation linkage is coupled between the second pivot and a piston that moves longitudinally within the cylinder. An applicator head coupled to a second end of the piston has an end exposed outside the cylinder for application to a person receiving treatment. An actuator selectively rotates the ring gear to cause the applicator head to have a first stroke length and at least a second stroke length.
