Patent number: 8069625Abstract: Fire resistant door, glazing, and mullion frames include intumescent material at least partially embedded in the frame adjacent the door or glazing. Trim materials are positioned over the intumescent material to prevent tampering with and damage to the intumescent material while improving the aesthetic appearance of the frame. The jamb trim has a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material retards the passage of heat and, by sealing the clearance space, inhibits the transmission of smoke, flames and gases from one side of the door or glazing to the other. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door or glazing.Type: GrantFiled: January 21, 2009Date of Patent: December 6, 2011Assignee: Washington Hardwoods Co., LLCInventors: Jim Harkins, John Gaydos

Patent number: 7587876Abstract: A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and as adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.Type: GrantFiled: December 22, 2006Date of Patent: September 15, 2009Assignee: E.M.E.H., Inc.Inventors: Gary F.

Publication number: 20070193220Abstract: The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication.Type: ApplicationFiled: February 21, 2007Publication date: August 23, 2007Applicant: POLYMER-WOOD TECHNOLOGIES, INC.Inventor: Evan R.

Patent number: 7232012Abstract: An elevator shaft door having a door panel composed of a front wall and rear wall, which walls are connected together by a thermally releasable material, wherein at least a part of the closing edge of the respective door panels consists of a profile member that is formed by the back wall or thermally non-detachably fastened to the back wall. In the case of a fire, the back wall separates from the front wall through release of the thermally releasable material, wherein the front wall curves by heat effect while the back wall with the closing edge retains the original shape.Type: GrantFiled: December 30, 2003Date of Patent: June 19, 2007Assignee: Inventio AGInventors: Josef A. Muff, Peter A. Spiess, Jules Christen

Patent number: 7185468Abstract: A door has a core that includes a porous layer having a thickness and two opposing major surfaces. In one construction, the core also includes three fire-retardant layers, and two of the fire-retardant layers are separated by the porous layer. The porous layer and the fire-retardant layers are coupled together. Other constructions include one or more fire-retardant layers in balanced or unbalanced placement around the porous layer.Type: GrantFiled: October 31, 2002Date of Patent: March 6, 2007Assignee: Jeld-Wen, inc.Inventors: Randy Jon Clark, Gary Lee Koepke, Keith Lynn Lewallen, Brent David Olson, William Robert Transue

Patent number: 7147741Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. The spaces between the ribs are filled with filler material such as foam plastic, and the cells in the cellular core are filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.Type: GrantFiled: February 15, 2005Date of Patent: December 12, 2006Inventor: Peter Sing

Patent number: 7143870Abstract: A door panel comprises a surface board 11 facing a hoistway, a back board 12 facing a hoistway, and a reinforcing member 13 for reinforcing the surface board 11 and the back board 12 . The back board is connected to the surface board or the reinforcing member by a connecting member 15 which is capable of losing the force of constraint against the surface board or the reinforcing member on high temperature conditions during a fire. This connecting member 15 prevents the door panel of the elevator hall door from being deformed during a building fire, and prevents the elevator hall door from falling, thus preventing smoke and flame from entering the hoistway.Type: GrantFiled: November 18, 2005Date of Patent: December 5, 2006Assignees: Kabushiki Kaisha Toshiba, Toshiba Elevator Kabushiki KaishaInventors: Masato Watabe, Hisato Ito

Patent number: 7028431Abstract: A fire-resistant, aluminum, cementitious-material-free, insulation-free door adapted to prevent the spread of fire and heat passing therethrough, consists of: a door frame, a door hingedly mounted on the door frame, the door having a bottom wall, a top wall, and side walls, the bottom wall, top wall and side walls enclosing a hollow central core not containing substantial amounts of insulating material, the bottom wall having an outside surface, and the top wall having an outside surface; and a layer of intumescent material on the outside surface of the bottom wall. A heat-activated self-closing mechanism allows the weight of the door to close the door in the vent of fire, by releasing gas from a supporting gas spring.Type: GrantFiled: September 5, 2003Date of Patent: April 18, 2006Assignee: Nystrom, Inc.Inventors: Jalil Tlemcani, Michael J.
