摘要： A method for making a hydraulic door closer includes the steps of molding material to form an elongated single-piece housing having a longitudinal cylindrical bore extending from a first open end thereof to a closed second end, a transverse intersecting bore, and mounting feet; installing a spring within the cylindrical bore at the closed end of the housing; installing a piston within the cylindrical bore in contact with the spring, the piston having a toothed rack thereon and an opening in each end to permit passage of fluid therethrough; installing a pinion gear in the transverse intersecting bore in meshed engagement with the toothed rack; installing an endplug with a port in the first end of the longitudinal cylindrical bore; and inserting a valve device through the port, for controlling flow of fluid through the piston, and for thereby controlling closing speed of the door. The single-piece housing as well as other components may be molded from metal or polymeric materials. Polymeric materials are preferred for their flexibility, lubricity, and moldability.

摘要： A valve for regulating speed of operation of a door closer, includes an elongated hollow tubular body having a closed first end with driving provisions thereon, an open second end, and an orifice in its sidewall adjacent its closed first end; an endplug for a cylinder bore of the door closer, the endplug having an axial port in which the closed first end of the tubular body is rotatably supported and which provides a fluid tight seal about the outer surface of the tubular body; an annular valve seat adjacent the endplug, the seat being fixed against rotation, and having an open portion and a closed portion which provide varying degrees of occlusion of the orifice when the tubular body is rotated; and a seal plate check valve captured against a piston head and occluding an opening therein during closing, the plate also providing a seal about the outer surface of the tubular body near the open second end thereof.

摘要： A self-trimming shield for the gap between a hinged door heel and its casing, includes a unitary strip of length approximately equal to the height of the door and made up of a sequentially arrayed plurality of elongated parallel panels. Opposite end panels of the plurality are attached, respectively, to the door and casing on the side opposite the hinge, while inner panels of said plurality are articulably connected with the end panels and with each other in such manner that, when the door is closed, the panels automatically fold to lie in close proximity to the door so that the shield appears to be an integral part of the door trim.
