May 19, 1970 H.' C. MEURET INSULATED PANEL DOOR Filed Aug. 1. 1968 L 4 A INVENTOR H HENRY c. MEURET S :3 3/ jMv Q fiA7 T YS.

United States Patent 3,512,304 INSULATED PANEL DOOR Henry C. Meuret, Oshkosh, Wis., assiguor to Morgan Company, Oshkosh, Wis., a corporation of Delaware filed Aug. 1, 1968, Ser. No. 749,547 Int. Cl. E06b 3/72 US. Cl. 49-501 9 Claims ABSTRACT OF THE DISCLOSURE This invention relates to door structures for closing building openings or the like and is more particularly concerned with improvements in a wooden door of panel type construction.

It has long been the practice in the construction of buildings to provide doors of various designs which are fabricated at the mill and supplied to builders for installation in the desired openings. Such door structures are customarily furnished in predetermined sizes and frequently in a package or assembly which includes a prefabricated and sometimes preassembled mounting frame for installation in a roughed in opening in a building wall. When such doors are employed for closing an opening in an ouside wall, there is, in most locations, a problem of providing adequate insulation against the passage of heat through the opening. Generally the door does not have sufficient insulating properties to be used alone and most often a storm door is considered necessary, especially in those areas where there is a winter period with low temperatures for an appreciable length of time. Some types of doors are now being installed which provide suificient insulation to eliminate the need for a storm door. These door structures are, however, flush type, solid wood, metal or composite material doors which generally have uniform thickness. In the standard construction of a wooden panel door, especially for outside use, stiles and rails are of substantial thickness which leaves awood section of approximately one-quarter inch at the juncture of the panel with the stile and rails. Under extreme cold temperatures it is possible for moisture to condense on the inside of this portion of the door panel or for frost to form thereon. The general object of the present invention is to provide a panel type wooden door in which the panels are so constructed that the overall insulation value of; the door is comparable to that of a flush type solid wooden door having a thickness corresponding to the thickness of the stiles and rails.

It is a more specific object of the invention to provide a panel type door construction for closing an opening in a building wall in which wooden stile and rail members of substantial thickness are employed with panels of special construction which are of substantially lesser thickness and which are so constructed and installed in the stile and rail frame work that the door has substan- 3,512,304 Patented May 19, 1970 "ice tially uniform insulating properties corresponding approximately to the insulating properties of a flush type solid wooden door having the same thickness as the stiles and rails.

It is a still more specific object of the invention to provide a panel type wooden door structure having stiles and rails of substantial thickness so as to provide adequate insulation properties and panel members set in the framework of the stiles and rails which are multiple construction with one of the plies being formed of a closed cell rigid foamed plastic material having a higher insulating value than wood and with the panels being sealed in the panel openings by strips of resilient foamed plastic which maintain the seal of a panel to the door frame work while allowing for some expansion and contraction of the panel.

It is another object of the invention to provide a paneled door of wood construction for closing an opening which is especially constructed and provided with magnetic edge seals so as to obtain a tight well insulated closure.

These and other objects and advantages of the invention will be apparent from a consideration of the door construction which is shown by way of illustration in the accompanying drawings wherein:

FIG. 1 is an elevation showing the interior face of a panel door installation;

FIG. 2 is a partial cross section taken on the line 2-2 of FIG. 1 to an enlarged scale; and

FIG. 3 is a fragmentary cross section taken on the line 33 of FIG. 1 to an enlarged scale.

Referring to the drawings there is illustrated in FIG. 1 a panel type wooden door mounted in wooden framing in a wall opening which incorporates the principal features of the invention. While a particular panel design or arrangement is shown, it is contemplated that various other panel arrangements may be employed, the illustrated design being frequently used in door structures provided for colonial or traditional style home dwellings.

The door 10 is mounted in a frame 11 for swinging movement on hinges 12 in the opening 13 about the sides and top of which the inner margins of the framing 11 extends. The illustrated door structure is fabricated with stile members 14 and 15 connected by top, bottom and intermediate cross rails 16, 17 and 18, and with rectangular panel openings 20 of the desired number and shape depending upon the panel design employed. The panels 21 which are set in the openings 20 have the ame construction, with the size and shape determined by the size and shape of the openings 20. Each of the panels 21, in the form shown, is constructed of the same materials and mounted in the associated opening in an identical manner, as illustrated in FIG. 2 of the drawings. The stiles 14, 15 and cross rails 16, 17 and 18 may be formed of glued up sections and covered with a suitable veneer facing as shown at 22 and 23 in FIG. 2. The edges defining each of the panel openings are provided with a continuous groove 24 for receiving the marginal portions of the panel 21.

The panel 21 comprises three plies of material consisting of outer plies 25 and 26 of wood andvan inner ply 27 of a material having a greater insulating value than wood. In addition, a vapor barrier forming member 28, in the form of a sheet or film material, for example metal foil or plastic film, is preferably sandwiched between the two wooden plies, 25 and 26 with the vapor barrier 28 between the interior wooden ply 25 and the center ply of insulation 27. The wooden plies 25 and 26 receive the same hip raised panel shaping, indicated at and 26' at their margins with the edge portions thereof seated in the groove 24. The groove 24 is provided with a resilient type of foam plastic strip 29 to effect a seal between the marginal edge of the panel 21 and the bottom of the groove 24. The width of the groove 24 and the thickness of the panel 21 at the margin of the latter is substantially less than the thickness of the stile and rail members due to the shaping of the panel marginal portions at 25' and 26. The insulating material constituting the panel center ply 27 is selected so as to provide at the thinnest panel section an insulating value approximating the insulating value of the thicker stile and rail. The insulating material employed is preferably a closed cell rigid foam plastic formed into a center ply 27 of substantial thickness which is laminated between the wood plies 25 and 26.

The door structure 10 is preferably prefinished on the exterior face thereof with a durable exterior finish having a high degree of impermeability to moisture. The interior face is preferably treated with a clear sealer to retard moisture intake after manufacture and before final job finishing which may then be conventional stain, paint or the like.

To secure the best seal possible between the door 10 and the frame 11 the door is provided about its side and top edges with an insert 30 of steel, or the like, to form an attracting surface for a duo-durometer magnetic vinyl Weatherstrip 31 which is of special construction. The insert 30 is seated in a groove or recess 32 which is cut in the edge of the door 10, about the top and sides thereof. The Weatherstrip 31 which is designed to extend along the top and the strike jamb 33 (FIG. 2) of the frame 11 is extruded integrally with a semi-rigid PVC vinyl stop cover 34 adapted to cover exposed faces of the stop member 35 which is secured to the jarnb 33 as shown. The Weatherstrip 31 comprises a tube portion 36 of rectangular cross section in which a magnetized strip 37 is encased and a flexible connecting tube portion 38 which mounts the same on the edge of the stop cover 34 confronting the edge of the door 10. A Weatherstrip 40 (FIG.

- 3) of similar construction but having an insert 41 of compressible material is provided on the edge of the stop member 42 which extends along the hinge jarnb 43. The Weatherstrip 40 is extruded as an integral portion of a semi-rigid vinyl stop cover 44 for the stop member 42. The seal is completed by the use, at the bottom of the door, of a conventional threshold sealing assembly having compressible inserts or fingers of vinyl plastic or similar material.

While particular materials and specific details of construction are referred to in describing the form of the invention which is illustrated it will be understood that other suitable materials and equivalent structural details may be resorted to within the spirit of the invention.
