Patent number: 9976334Abstract: The present utility model relates to a middle strip of a door frame, which can effectively solve the problem of insufficient strength existed in the middle strip of the door frame of the prior art. A middle strip of a door frame comprises a middle strip body, wherein a positioning hole is disposed in the middle strip main body along the length direction of the middle strip body, and the positioning hole is provided with a support frame in order to enhance the strength of the middle strip body, and the support frame is arranged along the inner wall of the positioning hole.Type: GrantFiled: August 4, 2016Date of Patent: May 22, 2018Assignee: USA WORLDWIDE DOOR COMPONENTS (PINGHU) CO., LTD.Inventors: Jerry Lee Monts De Oca, Gang Zhou

Patent number: 9212514Abstract: In order to pivot the encasement provided with glass panes about the pivotal axis thereof in an opening frame, a mobile blade at the bottom of the frame is pressed down and the pivotal movement is initiated in one direction or the other after unlocking the spring blocks bearing the blades covering the grooves of the vertical profiles of the frame. The seal having a U profile slightly lifts the blade and the covering blade of the upper profile of the frame, whereby the pivoting of the frame is continued until, if the lower blade has been released in the meantime, the ledge of the flange of the upper profile of the encasement abuts the side edge of this same blade while the ribbed blade enters the opening of the U seal of the upper profile.Type: GrantFiled: March 3, 2009Date of Patent: December 15, 2015Assignee: Orchidees Constructions S.A.Inventor: Eric Joray

Patent number: 6986225Abstract: An apparatus, such as a window in a frame which is mounted in a casing and that can be pivoted 180° within the casing for use on both faces. A pair of concealed hinges mounted, between the casing and the frame, provide pivots about which the frame is rotated. Further, a connector is mounted on opposing faces of the frame. An opening and closing device can be alternately connected and disconnected between the casing and opposing connecters. When disconnected, the frame is rotatable. Once rotated, the opening and closing device is reconnected to the connector on the opposite face of the window. Deformable sealing elements are mounted around the periphery of the frame and on either side of the concealed hinges to provide an air tight seal when the frame is closed.Type: GrantFiled: February 28, 2003Date of Patent: January 17, 2006Inventors: Finn Alexander Gjersoe, Thomas Gjersoe

Patent number: 6233879Abstract: A double pivotable door, particularly for use with modular office partitions is disclosed. The double pivotable door includes a frame, which is mounted to a partition by at least one hinge having a first axis of rotation. The frame include a door which is mounted to the frame and can rotate about a second axis of rotation, where the second axis of rotation is parallel but spaced from the first axis of rotation. The door can thus be mounted to partitions where there is limited space, and can rotate about the first axis, as a typical door, or rotate about the first and second axes simultaneously, thereby reducing by approximately half the clearance required for opening and closing the door. Preferably, the door includes a mechanism to prevent the door from pivoting about the second axis. Also preferably, the handle for the door is integral therewith.Type: GrantFiled: September 10, 1999Date of Patent: May 22, 2001Assignee: Groupe Pro-Plus Inc.Inventor: Jean Barbeau

Patent number: 5187837Abstract: A mullion mounted door hinge assembly for pivotally guiding upper and lower doors of a refrigerator. The hinge assembly includes a bracket which slidably accepts a generally cylindrical hinge pin. The hinge pin has a larger diameter center section and a pair of relatively smaller diameter end sections. Each of the end sections of the hinge pin extend into an accommodating opening in the upper or lower doors. The upper door is supported on an upwardly directed surface of the center section. A downwardly directed surface of the center section is supported by the lower door. A substantial portion of the weight of the upper door is transferred to the lower door and supported by the lower hinge means. A second preferred embodiment provides a stop means which engages a stop surface at a desired angular opening of the upper door of a refrigerator.Type: GrantFiled: November 14, 1991Date of Patent: February 23, 1993Assignee: White Consolidated Industries, Inc.Inventors: Rick L. Gunderson, David J. Donaghy

Patent number: 4833828Abstract: A kennel door which pivots about a vertical axis that bisects the door. The door is mounted within an opening in a frame. Disposed along the periphery of the frame are door seals which provide both a stop against which the door comes to rest and a seal against weather coming in through the opening when the door is in a closed position. When the door is in a closed position, the door seals are situated on diametrically opposite sides of the door such that they permit the door to rotate in one direction through the opening but not in the other direction. A spring biases the door in a closed position resting against the door seals.Type: GrantFiled: April 29, 1988Date of Patent: May 30, 1989Assignee: Gertrude FreedmanInventor: Arthur Gingrande

Patent number: 4489518Abstract: In a tiltable or pivotal window in which the frame and sash side members that are perpendicular to the axis of rotation have oppositely facing abutment surface sections on either side of the axis area, said abutment surface sections merge smoothly into each other through an abutment surface section formed as a helical surface of about 180.degree.. A continuous weather strip may be provided on one or both of the abutment surfaces. If such strips are provided on both surfaces, they may be magnetic with opposite transverse polarization to improve tightness and minimize sliding contact between the strips in the helical surface area.Type: GrantFiled: February 1, 1984Date of Patent: December 25, 1984Assignee: V. Kann Rasumussen Holding A/SInventors: Knud E. Nissen, Erik S. Berneke

Patent number: 4388779Abstract: Between regions of different air pressure, a door pivots on an axis located a substantial distance from the nearest edge; this edge moves inwardly as the door pivots about the door axis in a first phase of opening movement to relieve the difference in pressure on opposite sides of the door; pivot links then carry the door about a second axis, parallel to the first axis, in a second phase movement which moves the entire door outwardly to the open position.Type: GrantFiled: February 9, 1981Date of Patent: June 21, 1983Inventor: Carl R. Peterson

Patent number: 4281638Abstract: A damper assembly for solar heating systems and the like includes a damper blade pivotably mounted to a peripheral main frame. The damper blade is surrounded by a peripheral flexible sealing element which extends inwardly from the surrounding frame and which is inclined in a direction against the direction of closing damper blade movement. As the damper moves toward a closed position, its sides progressively engage the side portions of the sealing element, with the latter providing a seal with the peripheral face of the blade. The ends of the blade engage the sealing element prior to the blade finally reaching its ultimate closed position, with the sealing being complete at the moment of engagement and throughout the final range of blade movement. The peripheral sealing element is mounted to a subframe which is adjustable on the main frame to thereby sealingly accommodate a warped damper blade.Type: GrantFiled: January 17, 1979Date of Patent: August 4, 1981Assignee: Research Products CorporationInventor: John J. Delany

Patent number: 4070795Abstract: A door system of the swinging type to neutralize air draft effects on the door, which is conceived to allow panic exit and to psychologically induce the user to pivot the latter in a predetermined direction. This door system includes a pair of wings or panels having a releasable magnetic connection allowing normal bodily pivoting of the two wings as a simple swinging door and also allowing, for instance under panic, outward opening of the wing which normally opens inwardly. This door system includes a stopper and a door frame relatively arranged to define an oblique closing position for the door, and also includes a resilient strip of adjustable resilience engaging the stopper to prevent inadvertant opening of the panic wing.Type: GrantFiled: March 18, 1976Date of Patent: January 31, 1978Inventor: Jean Louis Lussier
