Abstract
The present invention provides a handheld driver having a housing with a handle and a trigger that drives a set of gears to rotate a shaft having a fitting for a socket, screwdriver bit or drill bit.
Claims19
A handheld device for rotating a drive shaft comprising:
- a housing comprising a handle extending from a gear housing;
- a first shaft that extends rotatably through the housing;
- a first drive gear secured to the first shaft;
- a trigger pivotably connected to the first shaft to position the trigger adjacent to the handle, wherein the movement of the trigger rotates the first shaft and first drive gear;
- a second shaft gear in contact with the first drive gear and supported on a second shaft that extends rotatably through the housing;
- a second drive gear positioned on the second shaft;
- a third shaft gear in contact with the second drive gear and supported on a slidable third shaft that extends rotatably through the housing and is slidable in the housing and the third shaft gear remains in contact with the second drive gear when slid;
- a third forward gear attached to the slidable third shaft on one side of the third shaft gear;
- a third reverse gear attached to the slidable third shaft on the other side of the third shaft gear;
- a pinion gear positioned between the third forward gear or the third reverse gear to engage selectively the third forward gear or the third reverse gear as a result of the position of the slidable third shaft;
- and
- a pinion shaft extending outwardly from the pinion gear through the housing, wherein the movement of the trigger rotates the gears to rotate the pinion shaft.

A device for pulling-out or pushing-in a screw comprising:
- a housing;
- a gear body disposed in the housing wherein a protruding shaft moveably secures perpendicular to a bottom gear and a top gear;
- a trigger that engages the bottom gear and the top gear, wherein the trigger moves the top gear and the bottom gear;
- the trigger selectively engages the bottom gear wherein rotation of the bottom gear in a first rotational direction rotates the top gear and rotation of the bottom gear in a second rotational direction rotates the top gear in an opposite direction;
- a rotatable shaft extending outwardly from the housing body;
- one or more cylindrical pieces comprising a pinion gear and a screw opposite the pinion gear disposed in the rotatable shaft;
- the rotatable shaft selectively rotates the pinion gear in a first rotational direction or a second rotational direction opposite the first rotational direction;
- a handle to grip while the trigger sets in motion the bottom gear and the top gear and the one or more cylindrical pieces and the screw.
