Mechanical hoistway access control device

A mechanical hoistway access control device for an elevator landing door, comprising:

• a first blocking member mounted on a position on a landing door frame above a landing door, the first blocking member pivotably attached between an upright position and a first horizontal position extending in the door opening direction about a horizontal shaft;
• and
• a second blocking member mounted on a position on a car door frame above a car door, the second blocking member pivotably attached between an upright position and a second horizontal position about a horizontal shaft, the second horizontal position being where the second blocking member protrudes out to the landing door side to block movement of the first blocking member,
• wherein the first blocking member is configured to fall down in the first horizontal position to mechanically block complete closing of the landing door when the landing door is opened with no elevator car at the landing, and
• wherein the second blocking member is configured to fall down in the second horizontal position before the first blocking member falls down to prevent the first blocking member from falling down in the first horizontal position when the landing door is opened in conjunction with the car door.
