Abstract:
1. An adjustable wrench comprising: an elongated handle having front and rear ends; first and second jaws mounted on the handle adjacent the front end; wherein the first jaw is movable toward and away from the second jaw; a spring which biases the first jaw toward the second jaw; a jaw locking member which is movable between a locked position and an unlocked position; wherein the locking member in the locked position secures the first jaw in a selected one of a plurality of secured positions to prevent movement of the first jaw toward the second jaw in response to the bias of the spring; and the locking member in the unlocked position allows the movement of the first jaw toward the second jaw in response to the bias of the spring; a jaw-opening actuator having first and second actuator positions; wherein in response to movement of the actuator from the first actuator position to the second actuator position, the locking member moves from the locked position to the unlocked position and the first jaw moves away from the second jaw; a tightening lever pivot; a tightening lever which is pivotally mounted on the handle about the tightening lever pivot and has a rear end rearward of the tightening lever pivot; and a locking member pivot having an axis about which the locking member is pivotally mounted; wherein when the locking member is in the locked position and a squeezing force is applied to the tightening lever and handle to move the rear end of the tightening lever toward the handle, the locking member moves perpendicular to the locking member axis to cause the first jaw to move toward the second jaw.
