    Abstract: A self-contained reciprocation mechanism is coupleable within an enclosure of a percussive massage device and is configured to receive an applicator head for stimulating a user's muscles. The self-contained reciprocation mechanism includes a spatial positioning bracket, a semi-cylindrical bracket, a piston, a motor, a crank, and a reciprocation linkage. The spatial positioning bracket is configured to receive the other interconnected components of the self-contained reciprocation mechanism and position said components relative to each other at close predetermined tolerances to assure that the interconnected components are properly positioned to provide consistent operating characteristics. The self-contained reciprocation mechanism is coupled within the enclosure using screws which extend through mounting tabs of the spatial positioning bracket.

    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.
