ABSTRACT:
A cable tension regulator capable of receiving an input force and transmitting an output force for use in mechanical control. The cable tension regulator comprises a pivot rod including a connector for operatively connecting the pivot rod to a support for pivoting of the rod relative to the support and a pulley mounted on the pivot rod for receiving cable. A cross bar having an opening for receiving the rod is capable of sliding longitudinally of the rod, and is constructed to hold ends of the cables. The regulator further comprises a spring having a first end held in a longitudinal position relative to the pivot rod and a second end operatively engaging and bearing against the cross bar for urging the cross bar to move on the rod in a direction generally away from the pulley to maintain tension in the cables. The regulator pivots about the transmission axis upon application of the input force. The cross bar is canted on the rod and frictionally engages the rod to lock the cross bar against movement longitudinally of the cross bar so that the spring is isolated and the input force passes substantially undiminished through the cable tension regulator for delivery by the cable tension regulator as the output force.
