Publication number: 20020129555Abstract: A high impact resistant rotationally molded door and process for molding the door has the hinge post integrally attached to the rotationally molded skin of the door. A hinge member is provided that has a perforate U-shaped metal sheet bonded to preferably the upper portion of the hinge post. The sides of the U-shaped metal sheet are spaced sufficiently apart so that registration with the subsequently rotationally molded plastic skin of the door occurs. This hinge member at the perforate metal sheet rapidly heats during rotational molding. The perforate metal thus bonds to integrally mold with the skin of the door. This bonding occurs as the hinge post is molded within the hollow door construction along its hinging edge. The hinge member attaches at the perforate U-shaped metal sheet to the skin of the door while all other portions of the hinge post are free to move with respect to the door. The door is thus formed without door warping during curing and shrinking of rotationally molded plastic door body.Type: ApplicationFiled: February 15, 2002Publication date: September 19, 2002Applicant: Chase Industries Inc.Inventors: Daniel Richard Eisenlord, Thomas Lee McCormick

Patent number: 6138412Abstract: A door opener and closer that provides motive power for opening and closing a door. A double acting cylinder pivotally mounted on the door is coupled to a roller arm. A roller on the roller arm is captive within a cage mounted to the door frame. The cylinder applies a force on the roller arm in one direction to open the door and in the opposite direction to close the door. The components are mounted in a manner such that none of the components project into the door opening. The door opener and closer eliminates the need for a separate closer. The door may be opened manually with minimum resistance.Type: GrantFiled: April 25, 1997Date of Patent: October 31, 2000Assignee: Chase Industries, Inc.Inventors: William H. Rieckmann, Wayne W.

Patent number: 5693271Abstract: A high impact resistant rotationally molded door and process for molding the door is disclosed in which a hinge member is integrally molded to the door along one edge only. This hinge member forms to the hollow door edge without door warpage during curing and shrinking of rotationally molded plastic door body. Door warpage is avoided by delaying full integral attachment of the hinge member to the door until curing of the injected foam interior which both bonds to the interior of the door and the hinge member. An improved seal and hinge seal is disclosed together with a placed window construction that can include both placement and shaping to meet the special order needs. Further improvements including the expedient of venting a rotationally molded door during the rotational molding process through an integrally molded hinge edge reinforcing member. This same venting scheme is utilized for enabling improved cooling of the door once molding of the hollow door shell has occurred.Type: GrantFiled: February 14, 1996Date of Patent: December 2, 1997Assignee: Chase Industries, Inc.Inventors: Carl Johnson, Michael Cloyd, Thomas McCormick
