Abstract
Abstract A device for tensioning a flexible element, such as a strap or cable. The device includes a U-shaped frame with aligned, circular openings in its opposite legs, and a slotted tensioning plate extending across the space between the legs of the U-shaped frame and rotatably received in said openings. A locking member is removably inserted to hold the tensioning plate against rotation. The locking member may be inserted and removed without shifting the tensioning plate axially.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
In a tensioning device for tensioning a flexible element, such as a strap or cable, said tensioning device including a frame with spaced legs having respective circular openings therein, and a tensioning member extending between said legs and rotatably received in said openings and having means thereon for the attachment of said flexible element which is to be tensioned by the rotation of said tensioning member, the improvement which comprises a locking member removably insertable into one of said openings in the frame to prevent rotation of said tensioning member therein, said tensioning member being oblong in crosssection at said one opening, said tensioning member having a minor cross-sectional dimension at said one opening that is substantially smaller than said one opening to provide a space for receiving said locking member, and said locking member extending from said one opening across the corresponding leg of the frame to an outer edge of said leg and having opposite end extremities extending respectively into said one opening and across said outer edge.
Claim 2
Dependent Claim
170 words
In a tensioning device for tensioning a flexible element, such as a strap or cable, said tensioning device including a frame with spaced legs having respective circular openings therein, and a tensioning member extending between said legs and rotatably received in said openings and having means thereon for the attachment of said flexible element which is to be tensioned by the rotation of said tensioning member, the improvement which comprises a locking member removably insertable into one of said openings in the frame to prevent rotation of said tensioning member therein, said tensioning member being oblong in crosssection at said one opening, said tensioning member having a minor cross-sectional dimension at said one opening that is substantially smaller than said one opening to provide a space for receiving said locking member, and said locking member extending from said one opening across the corresponding leg of the frame to an outer edge of said leg and having opposite end extremities extending respectively into said one opening and across said outer edge.
Claim 3
Dependent Claim
22 words
A tensioning device according to claim 1, wherein said locking member extends across the outside of said corresponding leg of the frame.
Claim 4
Dependent Claim
53 words
A tensioning device according to claim 2, wherein said tensioning member has an opening therein at the outside of said corresponding leg of the frame, and further comprising a retainer member removably received in said opening in the tensioning member and holding said locking member in place locking said tensioning member against rotation.
Claim 5
Dependent Claim
36 words
A tensioning device according to claim 3, and further comprising a second retainer member carried by said tensioning member and engaging the outside of the other leg of the frame to locate said tensioning member axially.
Claim 6
Dependent Claim
141 words
In a tensioning device for tensioning a flexible element, such as a strap or cable, said tensioning device including a frame with spaced legs having respective openings therein, and a tensioning member extending between said legs and rotatably received in said openings and having means thereon for the attachment of the flexible element that is to be tensioned by the rotation of said tensioning member, the improvement which comprises means for selectively locking said tensionIng member against rotation, said locking means being removably engageable between said frame and said tensioning member and removably insertable into one of said openings in said frame to prevent rotation of said tensioning member, said locking means having a generally U-shape and having opposite legs disposed respectively in said one opening and extending snugly across an outer edge of the frame leg having said one opening.
Claim 7
Dependent Claim
141 words
In a tensioning device for tensioning a flexible element, such as a strap or cable, said tensioning device including a frame with spaced legs having respective openings therein, and a tensioning member extending between said legs and rotatably received in said openings and having means thereon for the attachment of the flexible element that is to be tensioned by the rotation of said tensioning member, the improvement which comprises means for selectively locking said tensionIng member against rotation, said locking means being removably engageable between said frame and said tensioning member and removably insertable into one of said openings in said frame to prevent rotation of said tensioning member, said locking means having a generally U-shape and having opposite legs disposed respectively in said one opening and extending snugly across an outer edge of the frame leg having said one opening.
Claim 8
Dependent Claim
41 words
A tensioning device according to claim 5, wherein said tensioning member has an opening therein at the outside of said locking means and further comprising a pin removably received snugly in said last-mentioned opening and retaining the locking means in place.
Claim 9
Dependent Claim
35 words
A tensioning device according to claim 6, and further comprising a retainer member on said tensioning member at the outside of the other leg of the frame for holding the tensioning member against axial displacement.
Claim 10
Dependent Claim
45 words
A tensioning device according to claim 5, wherein said rotatable tensioning member is oblong in cross-section at said one opening, with its minor cross-sectional dimension substantially smaller than said opening to provide a space between them for receiving one leg of said U-shaped locking means.
