Abstract
A wrench, connectable to a standard square shaped extension, has a wrench head with opposed jaw faces which together define a plane that lies perpendicular to the respective jaw faces. A standard square shaped extension socket is affixed to the wrench head, where a standard square shaped extension can be inserted into the standard extension socket, along a direction that is non-orthogonal to the transverse plane. The standard extension socket can be attached to a frame of the wrench head, or to a rotatable guide which controls movement the opposed jaw face which is movable.
Claims20
A wrench connectable to a standard square shaped extension, comprising:
- a wrench head including opposed jaw faces each having a planar surface portion, the jaw faces mutually defining a transverse plane connecting the jaw faces and lying perpendicular to each of the planar surface portions;
- and
- a standard square shaped extension socket affixed to the wrench head, the standard square shaped extension insertable into the standard extension socket along a direction that is non-orthogonal to the transverse plane.
A wrench connectable to a standard square shaped extension, comprising:
- a frame having a fixed jaw face having a planar surface portion;
- a movable jaw including at least one jaw face having a planar surface portion;
- the planar surface portion of the at least one movable jaw face remaining parallel to the planar surface portion of the fixed jaw face as the movable jaw is moved;
- and
- a guide connected to the frame and the movable jaw to control movement of the movable jaw along a line, the guide including:
- an elongate rotatable shaft, a portion of the shaft rotatable within a portion of the frame, a portion of the shaft including threads, the shaft rotatable to move the movable jaw;
- a standard extension socket connected to the frame, the socket forming a standard square extension socket of the type having a square inner profile engageable with a square outer profile at an end of the standard square shaped extension.
A device for rotating a hex shaped fastener, comprising:
- a frame having a fixed jaw face defining a planar surface portion extending along a longitudinal axis thereof;
- a movable jaw including first and second jaw faces forming an angle of about 120 degrees relative to each other, each of the first and second jaw faces defining a planar surface portion along a longitudinal axis thereof;
- and
- a guide connected to the frame and the movable jaw to control movement of the movable jaw along a line forming an angle of one of about 19.1 and about 40.9 degrees with respect to an intersection of the line and the planar portion of the fixed jaw face, the guide including an elongate shaft including a first end engaged with the frame, and a second end at an end opposite the first end, the second end including a standard extension socket that includes a square shaped socket;
- the planar surface portion of the first jaw face remaining parallel to the planar surface portion of the fixed jaw face as the movable jaw is moved,
- the fixed, first, and second jaw faces defining a mutually intersecting plane, there being a part of the device lying upon the plane between the first jaw face and the fixed jaw face which is open to admit passage of the fastener along the plane.
