Definitions

  • My invention relates to door constructions and is particularly concerned with door panels formed of sheet metal.
  • One method of sound deadening has been to place a piece of cardboard or similar absorbent material on the back of the door panel. This expedient however cannot be used when the door panel is louvered since, in such a case, the cardboard could be seen through the louvers.
  • a further object of my invention is to provide a novel type of molding for a door and a unique way of attaching it to ythe door panel.
  • trim strip of novel cross-sectional shape which is attached to the front of the door panel.
  • This trim strip or lmolding is shaped in such a way that it contains but hides a strip ⁇ of non-metallic absorbent material, such as plastic, rubber, or paper.
  • the molding holds this sound absorbent material tightly cornpressed against the surface of the door panel and this is effective in minimizing ⁇ or eliminating objectionable sounds and noises as well as in providing a pleasing external appearance to the rface of the door panel.
  • FIGURE 1 is a perspective view showing a set of folding doors embodying the invention
  • FIG. 2 is an enlarged view of the louvered section of one of the four door panels of FIG. 1;
  • FIG. 3 is an enlarged cross-section taken along the line 3 3 of FIG. l;
  • FIG. 4 is an enlarged cross-section taken along the line ⁇ 4 4 of FIG. 2;
  • FIG. 5 is an enlarged cross-section of ⁇ one-half of a molding or trim strip, shown in the unstressed condition prior to welding of the trim strip Ato the door panel.
  • the door lconstruction shown in FIG. 1 comprises two pairs of folding door sets, each set comprising door panels 1 and 3. Except for the hardware, these panels are identical. Their speciiic construction is shown in more detail in my Patent No. 2,898,987, issued August lil, 1959, and in my copending application Serial No. 676,075, namelyd August 5, 1957, now Patent No. 2,943,675, issued July 5, 1960 which application also shows in FIGS. lOl-12 a louvered door construction which is the same in principle as that to be disclosed herein. Reference may be made to my patent and application for specific door construction and mounting features.
  • the panels 1 and 3 are hinged together on their adjacent edges so that they can be folded together with one panel overlying the other, as partially appears in the right of FIG. l.
  • each pair of panels is pivoted in the doorway so that each pair of panels can be pivoted and c lCe folded as a unitoutwardly to open up the full width of the doorway.
  • the -longitudinal side edges of the panels are turned back under in channel-like formation as seen at 4.
  • the Idoor panels shown in FIG. 1 have louvers 5 formed in the upper halves, ⁇ the lower halves being imperforate.
  • the louvers 5 are desirably of the shape and configuration revealed in FIGS. 2-4.
  • the bottom edge 7 of each louver is 4slit and then pressed rearwardly away from the front or outer face 9 0f the panel, a pleasing curved appearance being given to the body of the louver as seen at 11.
  • the opposite ends of the louvers are ⁇ curved as seen at 13 inwardly as they go from the bottom edge of the louver to the top portion thereof as delined by the line 15 of bending.
  • louvers leaves a narrow strip of material 17 between the edge 19 of the opening left by the adjacent louver and the line of bending 15. At the ends or edges of the louver ythe narrow strip 17 expands, or is widened, as the ends 13 curve away from the line 15 toward the lower edge 7 of the louver, thus leaving more or less triangularly shaped areas 20.
  • the vertical molding strips 21 are shown in FIGS. 2-5 and the horizontal strips 22 are of the same construction.
  • the molding strips that are used on the louvered upper portion and the unlouvered lower portion of the door are identical.
  • the strips are symmetrical ⁇ about their mid-plane so that the half-section of FIG. 5 is vsu-liicient to reveal the details of their construction.
  • the molding has a central at portion 23 which is adapted to be pressed flat against the face or surface of the ⁇ door panel and be spot welded to it, as shown at the places marked with an X and some of which are identified by the numeral 25.
  • the molding is flanged upwardly in a short section 27 and then extends upwardly on an incline in a section 2.9, the outermost leg portion 31 of the molding is ibent ⁇ downwardly at ⁇ corner 312 on an angle to the section 29, this angle preferably being somewhat less ⁇ than with the plane of the central section 23, as can be seen in FIG. 5.
  • An important feature is the fact that the end of the :outer leg section 31 extends a distance 33 below the bottom face of the center section 23 as is clear-ly evident in FIG. 5, which figure shows the preferred dimensional proporportions for the cross section.
  • I provide a sound absorbent non-metallic material 3S in the space 34 and preferably extending for the full length of the molding element 21.
  • a plastic material such as paper, sponge rubber, a hollow rubber tube, etc.
  • a thermoplastic resin such as polybutene, poly-iso-butene, butyl rubber, ⁇ or asphalt, ⁇ along with inert fill-ers or pigments is very desirable.
  • I have been satisfied with a material known on the open market as No. 5021 Mortite which is a synthetic resin plastic sealer extruded to a speciiic size.
  • the trim strip 21 to the particular location on the door panel face 9 shown best in FIG. 2, that is so that the central section 23 overlies the sections 20 of the door panel.
  • the sound deadening strips 35 on the inside leg, are in engagement with the thin transverse strip sections 17 of the door panel and act effectively to deaden these sections and prevent them from vibrating or causing noise.
  • the sections 17 will tend to embed themselves in the bottom portion of the absorbent material 35 when the molding and absorbent material is applied to the face of the panel.
  • the material 35 will act in this manner, along with its natural adhesive properties to hold the molding in po-sition during the spot welding operation.
  • the moldingr with the plastic material 35 inside is spot welded to the door panel prior to painting. After it has been attached the door may be painted and baked in a paint drying oven. It will be appreciated that it is a considerable advantage to be able to apply the molding prior to painting, rather than after the painting operation has been completed.
  • trim strips 21 I have provided the door panels 1 and 3 with a pleasing, attractive appearance.
  • a sound deadening material 35 I have provided a means extending ⁇ over a substantial part of the door panel for absorbing noise and elimina-ting vibrations. This means is effective on both louvered and unlouvered door areas.
  • the unusual construction arrangement of the molding itself and its location on the door panel provides an improved means of attachment of the molding to the door panel. From the manufacturing standpoint, the arrangement is such that the parts can be applied to the unfinished door and then the entire assembly painted and baked. This is in contrast with the use of a wood molding strip which must be cemented on to the finished or painted door and in the course of drying could be damaged, or damage the appearance of the door.
