Abstract
Abstract Flexible remote controls of the type in which at least one pushpull blade extends through a tubular sheath and is supported on its opposite sides by spaced balls are improved by replacing the usual metal ball-cage strips with lightweight, flexible plastic strips provided with perforations to hold the balls with the desired spacing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
119 words
In a tubular flexible remote control for transmitting push and pull forces wherein at least one flexible blade is in contact with a row of spaced balls positioned in a groove on each of its opposite faces, the improvement of a ball-cage strip for each said row of balls made of flexible plastic selected from the group consisting of tetrafluoroethylene polymer and fluorinated ethylene-propylene polymer having a thickness greater than the rAdius but less than the diameter of said balls and provided with spaced perforations larger than said balls to retain said balls loosely so that each of said balls can roll freely within its perforation and said strip is free to move longitudinally in contact with said blade.
Claim 2
Dependent Claim
119 words
