Abstract

The invention provides a cordless chiropractic adjustment device including a thrust element (80) capable of impacting a body contact member (10), a resilient spring (314) arranged to bias the thrust element towards the body contact member, and a motor (120). The motor is arranged to move the thrust element between a variable primed configuration in which the thrust element is held out of contact with the body contact member, and a fired configuration in which the thrust element is propelled by the resilient spring into contact with the body contact member through a range of different impact forces. The motor is provided with direct current by one or more batteries (150), which may be rechargeable.

Claims

1-13. -13. (canceled)

14. A cordless chiropractic adjustment device 200, adapted to receive at least one battery 150 which in use provides direct current to a motor, includes a thrust element 80 capable of impacting a body contact member 10, a resilient spring arranged to bias the thrust element towards the body contact member and a motor arranged to move the thrust element between a variable primed configuration, in which the thrust element 80 is held out of contact with the body contact member 10, and a fired configuration in which the thrust element 80 is propelled by the resilient spring 312, 314 into contact with the body contact member characterised in that a start thread member 110 is continuously variable by user selection in order to deliver variable forces to alter impact of the body contact member.

15. A device 200 according to claim 15, in which the body contact member 10 further comprises an anvil member 40.

19. A device 200 according to claim 15, including a switch 170, closure or opening of which switch is arranged to cause the motor to first propel the thrust element 80 to the fired configuration and subsequently withdraw the thrust element 80 to the primed configuration.

23. A device according to claim 15, comprising a thread start member arranged to convert rotation of a shaft of the motor to linear movement of the thrust element.

24. A device according to claim 15, comprising a tube member 90, 50, 60 through which the thrust element 80, in use, is propelled into the body contact member 10, and locking means having a locked configuration in which sliding of the thrust element 80 within the tube member 90, 50, 60 is prevented, and an unlocked configuration in which the thrust element 80 is slidable within the tube member 90, 50, 60.

25. A device according to claim 24, wherein the thread start member has an external male screw thread arranged to cooperate with a female screw thread of the tube member.

26. A device according to claim 23, in which the thread start member comprises a multi-start thread.

16. A device 200 as claimed in claim 16, in which the device further comprises a second resilient spring arranged to be held under compression by the anvil member 40 so as to control the amount of force with which the body contact member 10 is fired.

17. A device 200 as claimed in claim 17, in which the amount of compression applied to the second resilient spring 312 can be adjusted by an adjustment member arranged to cause relative longitudinal movement of the anvil member 40.

18. A device 200 as claimed in claim 18, in which the adjustment member is a nose cone member 30, and in which rotation of the nose cone member 30 causes relative longitudinal movement of the anvil member 40.

21. A device 200 according to claim 20, wherein the switch is arranged at an end of the device directly opposite to the body contact member 10.

22. A device according to claim 20, wherein the switch is arranged centrally within a concave palm rest for seating a user'"'"'s palm to enable one-handed stabilisation and activation of the device.
