The hinge and closure units are integral in that a hinge plate of the hinge unit serves as a support for components of the closure unit. Generally, the closure unit applies a pre-load force on the door when the door is in a closed position. When the door is between a closed position and a neutral force position, the closure unit applies a substantially constant closure force on the door. Once the door is opened beyond a first lock position, the closure unit applies resisting forces to the door when the door which act as a deterrent to further opening of the door. Rather than being expanded during door opening as with known spring closure mechanisms, the spring of the above described closure unit is compressed. Compressing the spring is believed to result in a more smooth and constant closure force on the door, as well as extending the useful life of the spring.Type: GrantFiled: August 29, 1997Date of Patent: April 27, 1999Assignee: General Electric CompanyInventor: Charles Henry Koopman

Patent number: 4325164Abstract: A door closing device which is easily mounted on, and easily removed from, an offset pivot hinge. The door closing device has an outer sleeve, an inner member rotatably mounted in the outer sleeve and a coil spring having opposite ends thereof connected to the outer sleeve and the inner member, respectively. The door closing device is mounted on, and operatively connected to, the pivot hinge by non-rotatably fitting the inner member and the outer sleeve with a pivot pin of the pivot hinge and a hinge plate pivoted on the pivot pin, respectively .The door closing device is provided with a door closing speed damping mechanism, a door stopper mechanism, and/or a preset mechanism for the door closing torque, which are assembled within the outer sleeve.Type: GrantFiled: August 15, 1979Date of Patent: April 20, 1982Assignee: Nippon Electric Industry Co., Ltd.Inventor: Kyoichi Sasaki

Patent number: 4155144Abstract: A damper device comprises first and second cylinders which are adjacent and rotatable with respect to each other and have respective hinge pieces, a piston operation member provided in the first and second cylinders in such a manner that it is rotatable with respect to the first cylinder, a piston member to which is fitted a pressure control member which is provided with a multithread section on the outer wall thereof and with a through-hole in the central portion thereof and a through-hole having a check valve, and a plurality of chambers provided in the second cylinder the chambers being divided into the upper and lower chambers by the piston operation member. These chambers are communicated with the through-holes, and a cylinder with a bottom is fitted to the piston member.Type: GrantFiled: November 16, 1977Date of Patent: May 22, 1979Assignee: Nikkey Co., Ltd.Inventor: Tomokichi Koganei

Patent number: 4100646Abstract: A self-closing hinge is described which comprises two hinge members intended to be secured to a door or the like and to a door frame, respectively, one of the hinge members having a cylindrical sleeve closed at the lower end and the other member having a hinge bolt turnably accommodated in said sleeve in order swingably to connect said hinge members. Said sleeve has a portion at its closed lower end provided with an internal thread, particularly a multiple thread of comparatively great pitch, said internal thread being arranged to coact with a corresponding external thread of a ring member in which the lower end portion of said hinge bolt is non-rotatably but axially displaceably journalled whereby said ring member, upon relative rotation in one direction between said hinge bolt and said sleeve, is screwed a distance upward in said sleeve to engage with an annular shoulder on said hinge bolt and upon continued relative rotation is screwed further upwards, thereby lifting said hinge bolt.Type: GrantFiled: February 28, 1977Date of Patent: July 18, 1978Inventor: Ewald Ingemar Emanuel Schubeis
