Abstract
A wrench for rotating a hex head fastener has a frame having one or two jaw faces. If the frame has two faces, they form a 60 degree angle between them. A movable jaw has two faces forming an angle of about 120 degrees relative to each other. A guide connected to the frame controls movement of the movable jaw along a line forming an angle of about 40.9 degrees with respect to a position of one of the frame faces.
Claims21
A device for rotating a hex head 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 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, thereby forming an open end wrench.
