Abstract

The present invention is an articulating hand power tool with a main housing having a longitudinal axis, a head portion rotatably engaged with the main housing for placement at a plurality of angles with respect to the longitudinal axis of the main housing, an integrated circuit board located within the main housing and at least one controller accessible from outside of the main housing for controlling the integrated circuit board.

Claims

1. An articulating hand power tool, comprising:

a main housing having a longitudinal axis;

a head portion rotatably engaged with the main housing so as to rotate within a plane which includes the longitudinal axis and configured for placement at a plurality of angles with respect to the longitudinal axis;

a motor within the main housing and having a first maximum height along the longitudinal axis;

an integrated circuit board located within the main housing and having a second maximum height along the longitudinal axis, wherein the second maximum height is greater than the first maximum height; and

a plurality of controllers accessible from outside of the main housing for controlling the integrated circuit board, each of the plurality of controllers offset from each of the other of the plurality of controllers along the longitudinal axis; and

a planetary gear system within the main housing and having a third maximum height along the longitudinal axis, wherein the second maximum height is greater than the third maximum height plus the first maximum height.

2. The articulating hand power tool of claim 1, wherein each of the plurality of controllers lies within the plane.

3. The articulating hand power tool of claim 2, wherein the plurality of controllers comprise:

a reversing button;

a trigger switch; and

a clutch control.

4. The articulating hand power tool of claim 3, wherein:

the integrated circuit board includes a linear potentiometer; and

the clutch control is operably connected to the linear potentiometer.

5. The articulating hand power tool of claim 3, wherein:

the integrated circuit board includes a light sensor; and

the trigger switch is configured to vary the amount of light received by the light sensor.

6. The articulating hand power tool of claim 3, wherein:

the integrated circuit board includes a linear potentiometer, a light sensor, and a slide switch;

the clutch control is operably connected to the linear potentiometer;

the trigger switch is configured to vary the amount of light received by the light sensor; and

the reversing button is operably connected to the slide switch.

7. The articulating hand power tool of claim 6, wherein:

the integrated circuit board includes an inwardly facing side and an outwardly facing side;

each of the plurality of controllers is located outwardly from the outwardly facing side; and

the linear potentiometer, the light sensor, and the slide switch are located on the outwardly facing side.

8. The articulating hand power tool of claim 7, wherein the integrated circuit board is substantially flat.

9. The articulating hand power tool of claim 1, wherein:

the integrated circuit board includes an inwardly facing side and an outwardly facing side; and

each of the plurality of controllers is located outwardly from the outwardly facing side.

10. The articulating hand power tool of claim 1, wherein:

the housing further comprises a battery receptacle; and

at least one of the plurality of controllers is located directly radially outwardly from the battery receptacle.

11. The articulating hand power tool of claim 10, wherein:

the integrated circuit board includes a linear potentiometer; and

the at least one of the plurality of controllers comprises a clutch control operably connected to the linear potentiometer and located directly radially outwardly from the battery receptacle.

12. The articulating hand power tool of claim 1, wherein:

the plurality of controllers comprise a trigger switch pivotably connected to the main housing at a lower portion of the trigger switch;

an upper portion of the trigger switch is located directly beneath a finger platform; and

an outermost portion of the finger platform is farther away from the longitudinal axis than an outermost portion of the trigger switch.

13. The articulating hand power tool of claim 9, wherein the plurality of controllers comprises a reversing button operably connected to the slide switch and slidable within the finger platform.
