Mechanism for automatically setting push-pull control cable device in standby/cancel mode

Abstract

A push-pull control cable device for automatically setting same in standby or a cancel mode. The device has an outer casing tube on which a tubular cap has an end fixed stationary relative thereto. An inner cable extends longitudinally guided through the tubular cap and into the device's outer casing tube for transmission of a desired control force. A member slidable axially in the tubular casing is disposed adjacent an opposite end thereof and has a reduced diameter tubular portion extending axially from the tubular cap. Inner cable extends through an opening in the slidable member and has terminal end extending into the tubular portion. A terminal block fixed to the terminal end is slidable in the tubular portion. An intermediate block slidable in the tubular cap is fixed to the inner cable spaced axially from the slidable member. A coil spring between intermediate block and the slidable member applies in an extended state a biasing force effectively causing the terminal block to bear against the slidable member in the absence of a force in the device restraining the inner cable from travel longitudinally toward the device so that the device assumes an operational standby mode for application of a push-pull control force by the depression of the slidable element or pulling it in a direction away from the device.
