Abstract

A power tool having a power tool body and a tool that is movably coupled to the power tool body. The power tool also includes a joystick control coupled to the power tool body, wherein the joystick control is operable as a user interface for affecting the operation of at least one function of the tool.

Claims

1. A portable, hand-held power tool comprising:

a power tool body having a handle portion adapted to be grasped by a hand of a user to support the power tool during use;

a tool that is movably coupled to the power tool body; and

a multi-axis joystick control coupled to the handle portion of the power tool body or to a portion of the power tool body adjacent to said handle portion, the joystick control comprising a multi-axis device that can be manipulated along first and second orthogonal axes, wherein the joystick control is operable as a user interface for affecting different operating functions of the power tool;

the joystick control affecting the operation of a first function of the power tool when manipulated along said first axis and affecting the operation of a second function of the power tool when manipulated along said second axis.

2. The power tool of claim 1, wherein the joystick control is an analog joystick control.

3. The power tool of claim 1, wherein the joystick control comprises a stick member, wherein the power tool body comprises an opening from which the stick member at least partially protrudes, and further comprising a cover member that extends over the opening to thereby completely cover the stick member.

4. The power tool of claim 1, wherein manipulation of the joystick control moves the tool relative to the power tool body.

5. The power tool of claim 1, wherein manipulation of the joystick control changes a rotation direction of the tool.

6. The power tool of claim 1, wherein manipulation of the joystick control varies a speed setting of the tool.

7. The power tool of claim 1, wherein the joystick control is programmable to thereby allow a user to program a manipulation sequence for the joystick control such that manipulating the joystick control according to the manipulation sequence causes a desired function.

8. The power tool of claim 1, further comprising a control circuit, and wherein manipulation of the joystick control supplies input signals to the control circuit for affecting the different operating functions of the power tool.

9. The power tool of claim 8, further comprising a motor and a power source, and wherein the control circuit comprises:

a low voltage portion that receives the logic level analog signal from the joystick control; and

a power electronics portion that is in communication with the low voltage portion and that communicates with the power source to supply a required voltage and current from the power source to the motor.

10. The power tool of claim 8, wherein the power tool comprises a portable, hand-held power drill.

11. The power tool of claim 1, further comprising a control circuit in electrical communication with the joystick control for receiving a signal from the joystick control, wherein the control circuit includes at least one relay.

12. The power tool of claim 1 wherein the handle portion is fixedly joined to the power tool body.

13. A portable, hand-held power tool comprising:

a power tool body having a handle portion adapted to be grasped by a hand of a user to support the power tool during use;

a tool that is movably coupled to the power tool body;

a clutch mechanism having a plurality of clutch settings,

wherein for each of the plurality of clutch settings, a different amount of resistance on the tool stops power delivery to the tool;

a multi-axis joystick control coupled to the handle portion of the power tool body or to a portion of the power tool body adjacent to said handle portion, wherein the joystick control is operable as a user interface for affecting the operation of at least one function of the power tool, and further

wherein manipulation of the joystick control changes between the plurality of clutch settings.

14. The power tool of claim 13, further comprising an indicator operable for indicating which of the plurality of clutch settings at which the clutch mechanism is set.

15. A portable, hand-held power tool comprising:

a power tool body having a handle portion adapted to be grasped by a hand of a user to support the power tool during use;

a tool that is movably coupled to the power tool body;

a chuck for selectively locking onto and releasing the tool;

a multi-axis joystick control coupled to the handle portion of the power tool body or to a portion of the power tool body adjacent to said handle portion, wherein the joystick control is operable as a user interface for affecting the operation of at least one function of the power tool; and

further

wherein manipulation of the joystick control causes the chuck to release the tool.
