Abstract

A line retention arrangement including one or more supports; and two or more clips, each clip having a base and a cantilever portion the two or more clips being oriented oppositely to one another, each clip mounted to the one or more supports. A method for retaining one or more lines at a string.

Claims

1. A line retention arrangement comprising:

one or more supports; and

two or more clips, each clip having a base and a cantilever portion the two or more clips being oriented oppositely to one another, each clip mounted to the one or more supports.

2. A line retention arrangement as claimed in claim 1 wherein one or more of the two or more clips includes a radiused corner.

3. A line retention arrangement as claimed in claim 1 wherein the arrangement employs one support.

4. A line retention arrangement as claimed in claim 1 wherein the arrangement employs two supports laterally spaceable from one another.

5. A line retention arrangement as claimed in claim 1 wherein a dimension of each clip between the one or more supports and the cantilever portion approximates a dimension of a line to be retained thereby.

6. A line retention arrangement in combination with a string comprising:

the arrangement as claimed in claim 1 affixed to the string.

7. A line retention arrangement as claimed in claim 1 wherein the cantilever portions of the two or more clips oriented oppositely to one another extend beyond a centerline between the two or more clips.

8. A line retention arrangement as claimed in claim 1 wherein the cantilever portions of the two or more clips oriented oppositely to one another fall short of a centerline between the two or more clips.

9. A line retention arrangement comprising:

a plurality of clips disposed along a string, the clips being spaced from one another by a distance related to a rigidity of a line to be retained thereby, the relation being dictated by the ability to bend the line sufficiently to clear a cantilever portion of a clip adjacent to a clip in which the line is already retained.

10. A line retention arrangement as claimed in claim 9 wherein the arrangement provides retention in both lateral directions.

11. A line retention arrangement as claimed in claim 10 wherein the arrangement provides retention radially.

12. A method for retaining one or more lines at a string comprising:

bending the one or more lines in one direction to clear a tip of a cantilever portion of a clip extending in a first direction;

urging the one or more lines under the cantilever portion of the clip;

bending the line in an opposite direction to clear a tip of a next adjacent cantilever portion; and

urging the one or more lines under the next adjacent cantilever portion.

13. A method as claimed in claim 12 wherein the urging is in one direction with respect to the cantilever portion and in the opposite direction with respect to the next adjacent cantilever portion.

14. A method as claimed in claim 12 wherein the bending is elastic.
