摘要:
A cable operated assembly for actuating a device comprises a housing assembly and a plunger movably mounted within the assembly for movement between return and actuating positions. A coil spring is mounted within the housing and biases the plunger toward the return position. A cable is movable in return and actuating directions relative to the housing and has one end engageable with the device to be actuated. The other end of the cable is connected to the plunger so as to permit movement of the cable relative to the plunger when the same moves toward the actuating position, and limiting relative movement of the cable when the plunger is moved toward the return position thereby to move the cable in the return direction. A second coil spring has a biasing force less than that of the first coil spring and urges the cable in the actuating direction, but is normally compressed. Movement of the plunger toward its actuating position compresses the first spring to relieve compression on the second spring and permits the second spring to urge the cable in the actuating direction. Extension of the first spring moves the plunger toward its position and the cable in the return direction thereby compressing the second spring.
