Abstract
Abstract A line tensioning device for maintaining a resilient sinuous bend in an elongated flexible line includes a pair of opposed semi-circular sections forming a rigid tube clamped coaxially about a portion of the length of the line and a pair of parallel elongated springs directed respectively between the opposite ends of the member and points along the line.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A device for maintaining a resilient sinuous bend in an elongated flexible line comprising: an elongated rigid member secured along a portion of said line throughout the length of said member; said member having first and second opposite ends; a first elongated spring secured at one end of said first spring to the first end of said member and secured at the other end of said first spring to a point on said line spaced away from said second end; and a second elongated spring secured at one end of said second spring to the second end of said member and secured at the other end of said second spring to a point on said line spaced away from said first end.
Claim 2
Independent Claim
122 words
A device for maintaining a resilient sinuous bend in an elongated flexible line comprising: an elongated rigid member secured along a portion of said line throughout the length of said member; said member having first and second opposite ends; a first elongated spring secured at one end of said first spring to the first end of said member and secured at the other end of said first spring to a point on said line spaced away from said second end; and a second elongated spring secured at one end of said second spring to the second end of said member and secured at the other end of said second spring to a point on said line spaced away from said first end.
Claim 3
Dependent Claim
19 words
The device of claim 1 wherein said rigid member comprises a tubular member disposed generally coaxially about said line.
Claim 4
Dependent Claim
17 words
The device of claim 2 wherein said tubular member is formed of two opposed semi-circular half sections.
Claim 5
Independent Claim
153 words
A device for maintaining a resilient sinuous bend in an elongated flexible line comprising: an elongated rigid member secured along a portion of said line, said member having first and second opposite ends; a first elongated spring secured at one end of said first spring to the first end of said member and secured at the other end of said first end of said member and secured at the other end of said first spring to a point on said line spaced away from said second end; a second elongated spring secured at one end of said second spring to the second end of said member and secured at the other end of said second spring to a point on said line spaced away from said first end, wherein said rigid member comprises a tubular member disposed generally coaxially about said line, said tubular member being formed of two opposed semi-circular half sections.
Claim 6
Independent Claim
153 words
A device for maintaining a resilient sinuous bend in an elongated flexible line comprising: an elongated rigid member secured along a portion of said line, said member having first and second opposite ends; a first elongated spring secured at one end of said first spring to the first end of said member and secured at the other end of said first end of said member and secured at the other end of said first spring to a point on said line spaced away from said second end; a second elongated spring secured at one end of said second spring to the second end of said member and secured at the other end of said second spring to a point on said line spaced away from said first end, wherein said rigid member comprises a tubular member disposed generally coaxially about said line, said tubular member being formed of two opposed semi-circular half sections.
