A door locking device is provided for positionally constraining an outwardly opening door against a stop of a cooperating door frame. The door locking device includes a door engaging member attached to the free-end of the door (i.e., the unhinged-end of the door), a threaded shaft having a first end pivotably mounted to the door engaging member and a second end opposite the first end for manual pivotal movement between an unlocked position (i.e., a position wherein the threaded shaft forms an acute angle with respect to the door) and an locked position (i.e., a position wherein the threaded shaft forms an obtuse angle with respect to the door), a wedge member slidably mounted on the threaded shaft, and a retaining nut disposed on the threaded shaft for axial movement thereon. In use, the door is positionally constrained against the stop of the door frame by closing the door, by moving the threaded shaft into the locked position, and by advancing the retaining nut along the threaded shaft until the retaining nut and the wedge member achieve a securing position (i.e., a position wherein the wedge member is immovably wedged between the retaining nut and the stop of the door frame). In order to bias the threaded shaft in the locked and unlocked positions, respectively, the door locking device may further include a cam member disposed on the first end of the threaded shaft and a spring member attached to the door engaging member for cooperative engagement with the cam member.
