## Abstract

Exemplary embodiments of massaging devices are disclosed herein. One exemplary embodiment includes a piston having a longitudinal axis, a massaging head connected to the piston, a motor located on a first side of the longitudinal axis and a handle located on a second side of the longitudinal axis. A drive mechanism for moving the piston and massage head is also included.

## Claims

### Claim 1

A percussive massager comprising:
a housing;
a piston having a proximal end and a distal end, the distal end of the piston having a bore;
a motor operatively connected to the proximal end of the piston, wherein the motor is configured to cause the piston to reciprocate at a first speed;
a drive mechanism that determines a predetermined stroke length of the piston; and
a quick-connect system comprising the distal end of the piston and a first massaging head,
wherein the quick-connect system allows a proximal end of the first massaging head to be inserted into or removed from the bore while the piston reciprocates the predetermined stroke length at the first speed,
wherein the motor has an output shaft that is configured to rotate about a rotation axis, and
wherein the drive mechanism comprises:
a flywheel operatively connected to the output shaft of the motor to rotate about a flywheel axis, the output shaft extending into the flywheel along the flywheel axis; and
a crank pin extending from the flywheel, the crank pin being operatively connected to the piston.

### Claim 2 (depends on 1)

The percussive massager of claim 1, wherein the motor is configured to cause the piston to reciprocate at a second speed.

### Claim 3 (depends on 1)

The percussive massager of claim 1, further comprising:
a control panel positioned on an exterior of the housing.

### Claim 4 (depends on 3)

The percussive massager of claim 3, wherein the control panel is configured to display one or more visual indicators.

### Claim 5 (depends on 1)

The percussive massager of claim 1, further comprising a handle portion, wherein the handle portion is on an opposite side of the flywheel with respect to the motor.

### Claim 6 (depends on 1)

The percussive massager of claim 1, further comprising a handle portion on the housing, wherein the motor and the handle portion are on opposite sides of a plane perpendicular to the flywheel axis that extends through the flywheel.

### Claim 7 (depends on 1)

The percussive massager of claim 1, further comprising a handle portion on the housing, wherein the motor and the handle portion are on a same side of a plane perpendicular to the flywheel axis that extends through the flywheel.

### Claim 8 (depends on 1)

The percussive massager of claim 1, wherein an offset between the flywheel axis and an axis of the crank pin determines the predetermined stroke length of the piston.

### Claim 9 (depends on 1)

The percussive massager of claim 1, wherein the motor is directly connected to the flywheel, and wherein the crank pin is directly connected to the flywheel.

### Claim 10 (depends on 1)

The percussive massager of claim 1, wherein the motor causes the piston to reciprocate at the first speed along a longitudinal axis.

### Claim 11 (depends on 1)

The percussive massager of claim 1, wherein the bore comprises a substantially cylindrical bore.

### Claim 12 (depends on 1)

The percussive massager of claim 1, further comprising a substantially cylindrical structure within the bore.

### Claim 13 (depends on 12)

The percussive massager of claim 12, wherein the substantially cylindrical structure comprises a cylindrical seat.

### Claim 14 (depends on 12)

The percussive massager of claim 12, wherein the substantially cylindrical structure comprises a magnet.

### Claim 15 (depends on 1)

The percussive massager of claim 1, wherein the proximal end of the first massaging head has a pocket to receive the distal end of the piston.
