  • Publication number: 20050246863
    Abstract: A hinge (10) that is arranged to be self-closing by the provision of two inter-engaged parts that are pivotable relative to one another, by each part including a respective barrel portion (30, 50), the two barrel portions (30, 50) being coaxially and end-to-end. Juxtaposed ends of the barrel portions (30, 50) each have a respective cam insert (35) therein. The cam inserts (35) are arranged such that an axial compressive force acting through the axis of the hinge (10) causes the hinge (10) to close. One of the barrel portions (50) is extended and has a damper (72) positioned therein. The damper (72) dampens relative axial movement of the two parts of the hinge (10). Thus, a door mounted on the hinge (10) in a door frame has its movement damped and tends not to slam closed.
