Multiple size nut driver

摘要

A nut driver for driving a nut within a range of nut sizes includes a housing. An open driver end thereof assumes a largest size of the nut sizes, and a selector end thereof terminates in a rotational knob that is positionable at any of a number of selectable radial positions. A cam is rotationally fixed with the knob and within the housing and terminates at a forward end with a selector ramp. A plurality of plungers are each slidably fixed within the housing and at a rear end thereof engage the selector ramp. Each plunger terminates at a forward end at a notched socket selector. A plurality of nested sockets each assume one of the different nut sizes and are slidably movable by at least one of the elongated plungers between a forward position within the open driver end of the housing and a rearward position.

1. A nut driver for driving a nut within a range of nut sizes all having a consistent perimeter shape, comprising:
a rigid, elongated housing have a driver end and a selector end, the driver end open and assuming a first size of the perimeter shape, the selector end terminating in a rotational knob positionable at any of a number of selectable radial positions each associated with a different nut size within the range of nut sizes; a cam rotationally fixed on the rotational knob for rotation within the housing, the cam terminating at a forward end with a selector ramp; a plurality of elongated plungers each slidably positioned within the housing, adapted at a rear end thereof for engagement with the selector ramp of the cam, and terminating at a forward end thereof at a notched socket selector; a plurality of nested sockets each having the perimeter shape and size of one of the different nut sizes within the range of nut sizes and smaller than the first size of the open driver end, each socket being slidably movable by at least one of the elongated plungers between a forward position locating a first end of the respective sockets within the open driver end of the housing and a rearward position spaced from the open driver end; whereby as the rotational knob is turned from one of the selectable radial 22 positions to the next, the selector ramp engages one of the plungers to push one or more of the outermost nested sockets into the forward position.
