Abstract
A door check for holding a door in an open position is disclosed, which is particularly useful for thin doors. The door check comprises a check body attached to the door and having an opening. The door check pivots with the door about a first axis. A main link is slidable through the door check opening as the door pivots. A second link is pivotably attached to the main link, and pivotably about a second axis with respect to a rigid member. As the check body pivots about the first axis, the second link pivots about the second axis and the main link translates through the opening in the check body. The main link may have an irregular surface so that a large force may be required to move the door back from the open position to a closed position.
