Abstract
In one embodiment, a valve wrench for rotating a knob may include a handle and a jaw assembly coupled to the handle. The jaw assembly may include a fulcrum member, a hook member and a bias member. The hook member may be pivotably coupled to the fulcrum member and may be aligned to the fulcrum member at a pivot angle. The fulcrum member and the hook member can form an opening there between to accept the knob. The bias member may be disposed between the fulcrum member and the hook member to bias the hook member towards the fulcrum member when the jaw assembly is engaged with the knob.
Claims20
A valve wrench for rotating a knob comprising:
- a handle;
- a jaw assembly coupled to the handle, the jaw assembly comprising a fulcrum member, a hook member and a bias member, wherein:
- the hook member is pivotably coupled to the fulcrum member and is aligned to the fulcrum member at a pivot angle;
- the fulcrum member and the hook member form an opening there between to accept a knob;
- and
- the bias member is disposed between the fulcrum member and the hook member to bias the hook member towards the fulcrum member when the jaw assembly is engaged with the knob.
A valve wrench for rotating a knob comprising:
- a handle;
- and
- a jaw assembly coupled to the handle, the jaw assembly comprising a hook member pivotably coupled to a fulcrum member and a bias member disposed between the hook member and the fulcrum member, wherein the hook member is aligned to the fulcrum member at a pivot angle, such that:
- when the fulcrum member and the hook member are engaged with a knob and the valve wrench is rotated in a tightening direction, the pivot angle is increased;
- and
- when the fulcrum member and the hook member are engaged with the knob and the valve wrench is rotated in a loosening direction, the pivot angle is decreased.
A valve wrench for rotating a knob comprising:
- a handle;
- a jaw assembly coupled to the handle, the jaw assembly comprising a fulcrum member, a hook member and a tool locating member, wherein:
- the hook member is pivotably coupled to the fulcrum member and is aligned to the fulcrum member at a pivot angle;
- the fulcrum member and the hook member form an opening there between to accept a knob;
- and
- the tool locating member is coupled to a top side of the hook member and extends at least partially over the opening, wherein a point of ingress to the opening is blocked and the valve wrench is unidirectional.
