Electrical lock

An electrical lock being installed on a door, the electrical lock comprising:

• a main body case;
• a dead bolt being movable between a locked position where the dead bolt protrudes out of the main body case, and an unlocked position where the dead bolt is housed in the main body case;
• a dead bolt moving element that is engaged with the dead bolt, and is structured to move the dead bolt;
• a drive source structured to move the dead bolt moving element;
• a power transmission mechanism structured to transmit power of the drive source to the dead bolt moving element;
• a manual-handling component, which is placed at an outdoor side of the door, structured to manually move the dead bolt, being at the locked position, to the unlocked position;
• a manual unlocking mechanism to which the manual-handling component is connected;
• and
• a restriction member structured to restrict a motion of the manual-handling component, the restriction member being formed in, or fixed to the dead bolt moving element;
• wherein, in a situation where the dead bolt moving element moves the dead bolt from the locked position to the unlocked position by use of the power of the drive source, the dead bolt moving element moves in a sequential order;
• from a standby position;
• by way of an unlocking start position where the dead bolt moving element makes contact with the dead bolt, and a travel of the dead bolt toward the unlocked position begins;
• to an unlocking finish position where the dead bolt arrives at the unlocked position;
• and
• the manual unlocking mechanism comprises:
• a second restriction member, to which the manual-handling component is connected, structured to restrict a motion of the manual-handling component, by way of contacting the restriction member;
• and
• a releasing member structured to move the dead bolt moving element, from the unlocking start position to the unlocking finish position, while being engaged with the dead bolt moving element, and the releasing member being moved by a motion of the manual-handling component;
• and
• at a time when the manual-handling component is operated in the situation where the dead bolt moving element is placed at the standby position, the restriction member and the second restriction member contact with each other to restrict the working range of the manual-handling component, in order to make the dead bolt immobile;
• and
• in a situation where the dead bolt moving element is placed at the unlocking start position, a restriction on the working range of the manual-handling component is removed in such a way that the dead bolt can move to the unlocking position.
