Abstract: A door system includes a door, a hinge assembly, and a door stop. The hinge assembly includes a door-side hinge plate secured to the door via a door-side screw, the door-side hinge plate including first knuckles, and a frame-side hinge plate configured to be secured to a door frame via a frame-side screw, the frame-side hinge plate including second knuckles. The door stop includes a cylindrical sidewall and a hinge pin. The cylindrical sidewall has a height and a diameter sized to at least partially contain the first knuckles and the second knuckles. The cylindrical sidewall defines a vertical slit through which the door-side hinge plate and the frame-side hinge plate extend to restrict a maximum angle of the door-side hinge plate relative to the frame-side hinge plate. The hinge pin interfaces with the door stop and is inserted through the first knuckles and the second knuckles.

Abstract: Various implementations of a hinge-mounted door stop are disclosed. In some implementations, the door stop is fashioned to be unobtrusive when installed on a door hinge assembly in order to reduce a possibility of being noticed in plain sight. Moreover, the door stop has a simple construction that allows quick and easy installation on a door hinge assembly relative to other configurations.
