ABSTRACT:
In bathroom doors which open inwards, it is impossible to remove the door if an obstruction such as a person disabled or laying against the door prevents the door from opening. This invention will permit the door to be removed instantly without destroying the door or the frame and causing possible injuries. This can be done with the door knob locked or unlocked from the outside of the bathroom.
