A door check assembly comprises a guide block and a one-piece or multi-piece elongate linkage having a range of travel back-and-forth through the guide block between a first position and a second position corresponding to open and closed positions, respectively, of a door assembly incorporating the door check assembly. A locking pin or other check-lock member is mounted in the guide block for movement between a locking position and an unlocking position. A check-lock actuator, e.g., hand-operated, electric, etc., is operatively connected via linkage directly or indirectly (i.e., alone or in combination with other link members) connecting the check-lock actuator to the check-lock member. The check-lock actuator is mounted in a door at a position, e.g., remote from the check-lock in order to be more convenient for the user. The check-lock actuator is operative via the linkage member to move the check-lock member between the locking position and the unlocking position. In the locking position the check-lock member, e.g., a locking pin, forms a positive locking engagement with the elongate linkage, which engagement is operative to prevent travel of the elongate linkage through the guide block and so, to prevent unintended closing of the door.
