Stroke self-adjusting mechanism for a control cable

A stroke self-adjusting mechanism for a control cable comprising

• a lever pivotally connected to a shaft and provided with both a first lock surface having a circular arc shape at one end thereof and a second lock surface which has a circular arc shape and which positions below and is almost concentric with the first lock surface;
• a fixed pin provided at a center area of radius in said first and second lock surfaces;
• a guide plate pivotally connected to said fixed pin at one end thereof and having a laterally extending hole;
• an adjusting lever having a movable pin at one end thereof and having a first locking pin and a second locking pin at the other end thereof, said movable pin being slidably engaged with said laterally extending hole, said first and second locking pins being contacted with and being pressed against said first and second lock surfaces respectively when the lever is rotated, and the second locking pin being engaged with a notch provided at the guide plate;
• a lock-releasing plate having vertically extending hole at one end thereof and having a lock-releasing pawl at the other end thereof, the lock-releasing plate being pivotally connected to said fixed pin by the vertically extending hole to move slidably within the guide plate;
• a lock-releasing stopper being capable of contacting with the lock-releasing plate;
• and
• an end fitting pivotally connected to said adjusting lever through said movable pin, an inner cable of the control cable being connected to the end fitting at one end thereof,
• whereby a working device which is connected to the other end of the inner cable being remotely controlled, and an expansion or a contraction of said inner cable being able to automatically adjust.
