  • Replacement hinge pin
    Patent number: 7891055
    Abstract: A replacement hinge pin to cure the problem of an open door that swings waywardly under the influence of gravity. The pin has a pair of oppositely-disposed and oppositely-directed bulges for frictional engagement with the roll-formed knuckles of a butt hinge. Rotational adjustment of the pin increases the friction in the hinge enough to prevent a door from swinging waywardly.
