Abstract
Abstract A tensioning device for a flexible element, such as a strap or cable. The tensioning device has a frame with spaced, parallel legs having axially aligned openings, an apertured bolt extending through the openings and having a polygonal head at one end outside one leg of the frame, and a nut on the other end of the bolt at the outside of the other leg to retain the bolt against axial movement. The one leg of the frame has an outwardly offset free end which presents two or more flat edges for locking engagement with the flats on the bolt head.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
230 words
In a tensioning device for a flexible element having a bolt with an aperture therein to receive the end of a flexible element to be wound around a bolt and a polygonal portion with adjoining flat surfaces adjacent one end thereof, a stem, and a frame having a base and substantially parallel legs projecting from the base, the legs having openings which are aligned with each other across the space between the legs so that the bolt is rotatable and axially adjustable in a lateral direction in the openings, the bolt having a nut for the end thereof opposite the polygonal portion, the improvement wherein the entire width of one of said legs at the side of the opening therein is offset laterally outward and substantially parallel to said one leg on the opposite side of said opening and presents only three polygonally disposed, adjoining flat edges which face toward the axis of said opening and are each elongated substantially perpendicular to the axis of said opening and are each spaced from said axis by substantially a radius of said polygonal portion of the bolt to a flat surface thereon to hold three sides of the polygonal portion of said bolt against rotation when said bolt is axially shifted toward the other of said legs, said one leg having no other edges for engaging said polygonal portion of said bolt.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
A tensioning device according to claim 1, wherein the free end of said one leg is offset laterally outward away from the other of said legs, and said polygonal portion of thE bolt is an enlarged polygonal head thereon at the outside of said one leg.
Claim 4
Dependent Claim
55 words
A tensioning device according to claim 2, wherein said edges are three in number, adjoining one another and arranged hexagonally around the half of said opening which is toward the free end of said one leg, and said head on the bolt is hexagonal and is substantially complementary to the hexagonal arrangement of said edges.
