发明名称 Manual balanced door with door closer arm
摘要 A manually-operable balanced door with improved operating characteristics is mounted to pivot around a guide roller so that a hinge side of the door swings inwardly from a door frame while a latching side of the door swings outwardly from the door frame. A door closer within the header is reversed from its position in a prior construction so that a rotatable closer shaft extends downwardly from a hinge side portion of the door frame header. The check shaft is coupled by a rigid closer arm to the latching side of the door, while the hinge side of the door is supported between upper and lower door pivot arms. A bearing assembly is disposed within a hinge end of the upper pivot arm and encircles a pivot pin that is supported within a cavity in a side jamb, the pivot pin being easily removable for disassembling the door from the door frame.
