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

1. A massaging device comprising:

a piston;

a massaging head connected to the piston;

the piston having a longitudinal axis;

a motor located on a first side of the longitudinal axis;

an elongated handle located on a second side of the longitudinal axis;

a drive mechanism for moving the piston and massage head; and

a thermally conductive drive housing at least partially surrounding the drive mechanism;

a first cavity at least partially enclosing the thermally conductive drive housing;

a heat sink in thermal conductivity with the thermally conductive drive housing; and

a second cavity at least partially enclosing the heat sink,

wherein the first cavity is separated from the second cavity by a barrier that prevents air from flowing between the first and second cavities.

2. The massaging device of claim 1 further comprising a control panel located above the elongated handle and wherein the elongated handle is separated from the control panel by a wall.

3. The massaging device of claim 2 wherein the control panel includes at least one of an audible or a visual feedback device.

4. The massaging device of claim 1 further comprising a data connection for transferring stored data indicative of the use of the massaging device, to or from the massaging device.

5. The massaging device of claim 1 wherein the drive mechanism comprises a crank bearing and one or more spring bars, wherein the one or more spring bars contact one or more walls of a pocket that receives the crank bearing.

6. The massaging device of claim 1 wherein at least a portion of the piston is hollow.

7. The massaging device of claim 1 wherein the drive mechanism comprises a fly wheel having an offset cylindrical projection that fits into a crank bearing.

8. The massaging device of claim 1 further comprising two or more cylindrical bearings separate from one another, wherein the bearings retain the piston and at least one bearing is on a first side of a connection between a drive mechanism and the piston and at least one bearing is on a second side of the connection between the drive mechanism and the piston.

9. The massaging device of claim 1 further comprising a quick connect mechanism for connecting the massaging head to the piston.

10. The massaging device of claim 9 wherein the quick connect mechanism comprises at least one magnet and the massaging head is connected to the piston by magnetic force.

11. A massaging device comprising:

a handle;

a piston;

a massaging head attached to the piston;

a motor;

a drive mechanism for converting rotary motion of the motor to linear motion to drive the piston back and forth in a reciprocating motion;

a processor;

memory;

a data connection in circuit communication with the processor;

logic for transmitting stored data indicative of the use of the massaging device between the massaging device and a remote device between the massaging device and a remote device; and

a thermally conductive drive housing at least partially surrounding the drive mechanism;

a first cavity at least partially enclosing the thermally conductive drive housing;

a heat sink in thermal conductivity with the thermally conductive drive housing; and

a second cavity at least partially enclosing the heat sink,

wherein the first cavity is separated from the second cavity by a barrier that prevents air from flowing from the first cavity to the second cavity.

12. A massaging device comprising:

a handle;

a motor;

a drive mechanism for converting rotary motion of the motor to reciprocating motion;

a piston movable in a linear reciprocating motion connected to the drive mechanism;

a massage head attached to the piston;

a heat sink in thermal communication with the motor;

a housing having a first cavity and a second cavity;

the first cavity at least partially surrounding the motor;

the second cavity at least partially surrounding the heat sink;

the first cavity being separated from the second cavity by a barrier that isolates the interior of the first cavity from the interior of the second cavity and prevents air from flowing between the first and second cavities; and

one or more openings into the second cavity for allowing air to flow over the portion of the heat sink in the second cavity to dissipate heat from the motor.

13. The massaging device of claim 12 further comprising a control panel located on the housing above the handle and wherein the handle is separated from the control panel by a wall.

14. The massaging device of claim 12 wherein the drive mechanism comprises a crank bearing and one or more spring bars, wherein the one or more spring bars contact one or more walls of a pocket that receives the crank bearing.

15. The massaging device of claim 12 further comprising control circuitry, wherein at least a portion of the control circuitry is located in the handle and wherein the handle is separated from the control circuitry by a wall.

16. The massaging device of claim 12 further comprising two or more cylindrical bearings separate from one another, wherein the bearings retain the piston and at least one bearing is on a first side of a connection between a drive mechanism and the piston and at least one bearing is on a second side of the connection between the drive mechanism and the piston.

17. The massaging device of claim 12 further comprising a quick-connect mechanism for connecting the massaging head to the piston.

18. The massaging device of claim 17 wherein the quick-connect mechanism comprises at least one magnet and the massaging head is connected to the piston by magnetic force.
