Door engagement device

A door engagement device configured to engage with an engaged part, which is mounted to a landing door or a car door of an elevator, and thereby be able to transmit driving force to open and close the car door or the landing door, the door engagement device comprising:

• a first member that extends in a vertical direction and is able to come into contact with the engaged part from a door closing direction side;
• a second member that extends in the vertical direction at a position with a distance from the first member to a door opening side and is able to come into contact with the engaged part from a door opening direction side;
• a first link member that forms a parallel link mechanism in cooperation with the first member so as to enable the first member to pivotally move between a predetermined first position and a predetermined second position located closer to the door closing direction side than the first position while keeping a posture of the first member;
• and
• a first restricting part that releasably restricts the pivotal movement of the first member at the first position;
• a second link member that forms a parallel link mechanism in cooperation with the second member so as to enable the second member to pivotally move between a third position, at which the second member is located close to the first member, and a forth position closer to a door opening direction side than the third position while keeping a posture of the second member;
• and
• a second restricting part that restricts the second member from pivotally moving at the third position, wherein
• the second link member is connected to the base to be relatively rotatable around a shaft S3 extending in the entrance direction, while being connected to the second member to be relatively rotatable around a shaft S4 extending in the entrance direction,
• the second restricting part includes a second link member contact part that comes into contact with the second link member, thereby restricting the second link member from further pivotally moving, and
• the second link member, when it has come into contact with the second link member contact part, takes a position allowing a virtual line Z connecting the shaft S3 and the shaft S4 to be downwardly inclined toward the engaged part side so that the second link member is subjected to a downward force when the engaged part has come into contact with the second member.
