Abstract
The disclosure is directed to a self-adjusting wrench, comprising a movable jaw member, a fixed jaw member a biasing member and a handle, wherein the movable jaw member, the fixed jaw member and the handle engage to self-adjust and lock the gap between the movable jaw and the fixed jaw upon applying pressure to the jaws using the handle.
Claims20
A self-adjustable wrench comprising:
- a fixed jaw member having a distal end and a proximal end fixed to and extending from a wrench housing, the housing defines a channel configured to receive a handle, and a chamber configured to receive a portion of a movable jaw member;
- a movable jaw member having a distal end and a proximal end, the proximal end slidably operably coupled to the fixed jaw wrench housing;
- an elongated handle operably coupled to the wrench housing, the handle having a proximal end and a distal end, and is capable of sliding toward and away from the fixed jaw, wherein the handle's distal end comprises an anterior wedge and an opposite posterior wedge;
- a two dimensional biasing member, operably coupled to the proximal end of the movable jaw member, the wrench housing and the distal end of the handle, capable of simultaneously biasing the movable jaw member toward the fixed jaw and the handle away from the fixed jaw;
- and
- a wrench housing cover, wherein the proximal end of the movable jaw member is configured to engage the distal end of the handle to lock the gap between the fixed jaw and movable jaw member.

A method of turning a threaded rotating member, comprising:
- using a handle, pressing a self-adjusting wrench against the rotating member, the self-adjusting wrench comprising a fixed jaw having a distal end and a proximal end fixed to and extending from a wrench housing, the housing defines a channel configured to receive a handle, a chamber configured to receive a portion of a movable jaw member, an immobilizing boss, a biasing member boss, and a biasing member tab;
- a movable jaw member having a distal end and a proximal end, the proximal end slidably operably coupled to the fixed jaw wrench housing;
- an elongated handle operably coupled to the wrench housing, the handle having a proximal end and a distal end, and is capable of sliding toward and away from the fixed jaw within the wrench housing channel, wherein the handle's distal end comprises an anterior wedge and an opposite posterior wedge;
- a two-dimensional biasing member, operably coupled to the distal end of the movable jaw, the wrench housing and the distal end of the handle, capable of simultaneously biasing the movable jaw toward the fixed jaw and the handle away from the fixed jaw;
- and a housing cover, wherein the proximal end of the movable jaw is configured to engage the distal end of the handle to lock the gap between the fixed jaw and movable jaw;
- adjusting the gap between the fixed jaw and the movable jaw member;
- and
- applying torque effective to rotate the member.
