초록 ▼

A door closer having a housing defining a fluid containing chamber and a fluid reservoir and including a piston supported in the chamber for movement in one and an opposite direction in response to respective opening and closing movements of a door. A first fluid passageway defined by the housing provides communication between the chamber and the reservoir for the free passage of fluid from the chamber to the reservoir in response to initial movement of the piston in the one direction. A second fluid passageway spaced in the one direction from the first fluid passageway contains a ball check valve spring biased to closed position for resisting the flow of fluid from the chamber through the second passageway to the reservoir. The valve is threadably adjustable relative to the housing to regulate the resistance to fluid flow. A third fluid passageway spaced from the first passageway and disposed in bypassing relation to the second fluid passageway includes an adjustable metering orifice and provides a free flow path from the chamber to the reservoir. The size of the metering orifice is also adjusted by threadably adjusting the valve relative to the housing.

대표청구항 ▼

A door closer to be secured to a door which can be opened by applying an opening force which, if larger than a selected force when the door is opened beyond a predetermined angle, could subject the door to damage comprising a closer housing including a cylindrical chamber having opposed ends, a cylindrical piston located proximate one of said ends and slidably displaceable within said cylindrical chamber and defining with said other end a variable volume for containing a non-compressible liquid, coaxial compression spring means located within said volume, means for displacing said cylindrical piston as said door is opened to compress said spring means and to impart a pressure to the contained liquid, means operable when the door has been displaced beyond the predetermined angle to release liquid from said variable volume including a cylindrical housing open at one end and closed at the other end, an inlet conduit in said closed end, a sealing ball, second spring means for urging said sealing ball against said inlet conduit to prevent flow of liquid therethrough into said cylindrical housing below a selected pressure, conduit means for connecting said variable volume and said inlet conduit, and a second conduit in said cylindrical housing downstream of said sealing ball, said second conduit communicating with said conduit means so that when the pressure of the liquid is below a selected pressure, the liquid will be released through said second conduit and when the pressure is above said selected pressure, the liquid will be conjointly released through said inlet conduit and said second conduit.
