Abstract
A padlock includes a lock body and a U-shaped shackle fitted in the lock body and movable between a released position and a locked position. A bolt member is disposed in the lock body and cooperates with a turnable force transmission member and the shackle, when the shackle is in the locked position, to retain the shackle in the locked position when the force transmission member is in a first position and to permit the shackle to move to the released position when the force transmission member turns to a second position. A key-actuated cylinder lock mechanism includes turnable locking discs and a control member which acts directly on the force transmission member for turning the force transmission member from the first position to the second position when a lock cylinder is turned from an opening position to a locking position. A spring is effective between the lock cylinder and the force transmission member. The spring is loaded by turning the lock cylinder to the locking position, whereby the spring exerts a force urging the force transmission member back to the first position.
