ABSTRACT:
An improved doorstop provides increased safety along with the simplified operation over previous doorstops. The doorstop is adapted to be mounted directly to the door in close proximity to an immovable surface such as the floor or a door channel. The device includes a frictional contact member which is leveraged from a first position away from the immovable surface to a second position in frictional contact with the surface. The improved doorstop is useful on sliding doors as well as hinged doors.
