Door opening and closing apparatus

摘要

A door opening and closing apparatus includes a lock mechanism having an engaging member that engages with a lock member provided in a door when the door is in a fully closed state, and a link mechanism that has three link members, is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state. A central link member among the three link members has a first face and a second face that are pressed by a projecting shaft. The link mechanism changes to the bent state when the first face is pressed, and changes to the linear state when the second face is pressed. The first face and the second face are provided so as to have a positional relationship in which the first face and the second face intersect each other.

主权项

1. A door opening and closing apparatus for opening and closing a door, comprising:
an actuator that moves the door in an opening direction and a closing direction; and a lock mechanism that holds the door in a fully closed state, and has an engaging member which engages with a lock member provided in the door when in the fully closed state, and a link mechanism which has three link members including a central link member provided between two link members of the three link members, is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state, wherein the central link member has a first face that is pressed by a projecting shaft moved by the actuator in order that the link mechanism changes from the linear state to the bent state, and a second face that is pressed by the projecting shaft in order that the link mechanism changes from the bent state to the linear state, and the first face and the second face are provided so as to have a positional relationship in which the first face and the second face intersect each other.
