US 8,770,069 B2 · Automatically-configurable screwdriver assembly

Abstract

An automatically-configurable screwdriver assembly includes a shaft with a hollow interior portion, a proximal end, and a distal end. A first blade is fixedly coupled to the distal end of the shaft to prevent motion in a proximal direction and a plunger is at least partially located within the hollow interior portion of the shaft and slidable therein between an extended position and a retracted position. A compression member exerts force on the plunger in a distal direction and a second blade is mechanically coupled to the plunger so that, when the plunger is in the extended position, the first blade and second blade extend approximately equidistant from the distal end of the shaft and form a substantially perpendicular configuration with one another and when the plunger is in the retracted position, the first blade extends a greater distance from the distal end of the shaft than does the second blade.

An automatically-configurable screwdriver assembly comprising:

a shaft:
having a proximal end;
having a distal end;
having a length separating the proximal end and the distal end;
and
defining a hollow interior portion;
a first blade fixedly coupled to the distal end of the shaft to prevent motion in a proximal direction;
a plunger at least partially located within the hollow interior portion of the shaft and slidable therein between an extended position and a retracted position;
a compression member exerting force on the plunger in a distal direction;
and
a second blade mechanically coupled to the plunger,
wherein, when the plunger is in the extended position, the first blade and second blade extend approximately equidistant from the distal end of the shaft and form a substantially perpendicular configuration with one another and when the plunger is in the retracted position, the first blade extends a greater distance from the distal end of the shaft than does the second blade.
