Abstract
The present invention generally relates to a T-Handle wrench. In one aspect, a wrench is provided that includes a shaped handle. The wrench further includes a plurality of jaws operatively attached to the handle. The wrench also includes a sleeve member disposed around the jaws. Additionally, the wrench includes a push button assembly configured to move the sleeve member relative to the jaws, wherein the movement of the sleeve member causes the jaws to move between a retracted position and an extended position. In another aspect, a method of operating a wrench is provided.
Claims28
A wrench comprising:
- a handle;
- at least two jaws operatively attached to the handle and movable between retracted and extended positions, wherein the jaws are biased toward the extended position by a biasing member;
- and
- a sleeve member axially movable relative to the jaws, wherein movement of the sleeve member causes the jaws to move between the retracted and extended positions relative to an object to be engaged by the jaws and wherein the sleeve member is biased toward a position in which the jaws are in the retracted position.
A method of operating a wrench, the method comprising:
- providing a wrench having a shaped handle with jaws operatively attached via pin members and a sleeve member disposed around the jaws;
- and
- moving the sleeve member from a first position, in which the sleeve member holds the jaws in a retracted position, to a second position, in which the sleeve member allows the jaws to move to an extended position, wherein moving the sleeve member comprises overcoming a biasing force that biases the sleeve member towards the first position.
A wrench comprising:
- a T-shaped body;
- at least two jaws, wherein each jaw has an upper portion pivotally attached to the T-shaped body and a lower portion that includes an outer surface, the lower portion of the jaws being pivotally movable between a retracted position and an extended position;
- and
- a sleeve member disposed around the jaws, wherein:
- the sleeve member has an inner surface that interacts with the outer surface of the lower portion of each jaw when the sleeve member moves relative to the jaws between a first position, in which the sleeve member holds the jaws in the retracted position, and a second position, in which a biasing member urges the jaws to the extended position;
- and
- the sleeve member is biased towards the first position.
A self-adjusting wrench, comprising:
- a handle;
- at least two opposing jaws disposed on the wrench opposite the handle;
- a first biasing member biasing the jaws towards an extended position;
- a user-adjustable sleeve member movable between a first position, in which the sleeve member holds the jaws in a retracted position, and a second position, in which the jaws are allowed to move to the extended position;
- and
- a second, user-adjustable biasing member biasing the sleeve member towards the first position.
