  • the panels I and 2 are too thin to afford the necessary anchoring for the teeth on the reinforcing bars since these must not project outside the panels. Therefore, ribs 7 are provided on the inner sides of the panels and are secured thereto with glue or by some other suitable means, the ribs being of wood or other suitable material for anchoring the teeth 4 on the reinforcing bars 3.
  • insulation plates 8 providing insulation against heat, cold, and sound, are arranged against the inner sides of the panels between the reinforcing bars. These plates are put in place before the rails 5 and edgings are placed on the door, and a plate 9 of corrugated board or the like is placed between the insulating plates 8 to hold them pr ssed against the inner surfaces of the panels I and 2.
  • FIG. 6 there is placed between the insulating plates 8 an additional fireproof plate or body Ha of fireproof material, so that the panels will be fireproof insulatedfrom each other.
  • an edging or rail covering l I of metal whose sides are bent at right angles and cover the edges of the panels I and and have edges 12 bent at right angles, which are pressed into grooves formed in the outer sides of the panels I and 2, whereby the edging or rail covering is fastened to the edge of the door without the use of screws or other special fastening means.
  • fireproof insulating plates l3 are positioned against the inner sides of the panels I and 2, between which plates I3 is arranged an intermediate layer of corrugatedboard or the like.
  • hooks or lateral projections 14 (see Figures 5 and 9) on the reinforcing bars, or instead a thin iron plate l5 may be positioned between the panels and the insulating plates.
  • This iron plate 15 is selected thin enough so that the teeth of the reinforcing barscan be pressed through the plate [5 and into the material of the panels.
  • fine meshed netting [8 may be interposed between the panels and the insulating plates.
  • the metal edging or rail covering 27 is formed with an enlarged reentrant groove I3 at one corner, wherein is arranged a tightening seal I9 of rubber or other elastic material.
  • This tightening seal I9 is formed with a tubular part [9a and integral therewith is a flange portion [9b which is thinnest next to the tubular part and thickest at its other end, whereby it is snugly anchored between the converging walls of the groove.
  • the rubber seal is so formed that a sealing part 2! lies against the edges of the groove [8.
  • the groove [8 and the flange portion [91) may also be formed with parallel sides, as indicated in Figure 8, and in that case both parts are formed with grooves running longitudinally thereof or with other roughening to hold the flange portion of the seal in the groove.
  • the sealing part 19a of the seal is tubular and in accordance with the invention so arranged that when the door is closed, it engages first one side thereof against the door jamb 22 and is thereby bent over into engagement with the door post 23, so that there then exist two sealing surfaces arranged at with respect to each other, with an air channel 24 in the corner between the door jamb 22 and the door post 23.
  • the simple reinforcing bar 3, shown in Figure 9, is stamped out of sheet material and formed with spearpoint-shaped teeth 4, whose strength is increased by bending them at an angle.
  • Reinforcing bars for doorsiwith fireproof insulating plates may be formed with the hooks or lateral projections [4, consisting of separate teeth stamped out of the bar material and bent at a right angle to the plane of the bar. These hook-like arrangements will hold the insulating plates in position, even if one of the panels should be consumed by fire.
  • dual reinforcing bars such as shown in Figures 10, 10a, and 11, 11a, wherein are shown a dual reinforcing bar 21 composed of two bars with a U-shaped cross section with toothed edges and the backs of the bars firmly connected to each other; and a dual reinforcing bar comprising two single bars of the type shown in Figure 9, connected to each other by connectin pieces 28 with tabs 28a which are securely riveted to the bars 3.
  • the reinforcing bars may be formed on their ends with extra teeth 4a to be pressed into the wood of the edgings.
  • the reinforcing bars in that case must be so arranged that the teeth 4a are exactly in position to be pressed into the edgings when these are put on the door.
  • the reinforcing of the door may be accomplished with whole reinforcing bars or withlonger or shorter pieces of reinforcing bar.
  • the reinforcin bars may also be bent in any suitable geometrical form, and the construction of details may of course be varied.
  • hinge leaves 30 of the hinges 29 arranged inside both the edging H or IT, as the case may be and the steel case 3
  • threaded holes are provided in the hinge leaves on the related side of the hinges.
  • the hinge leaves on the door are fastened in specially devised fastening irons 34, which may be fastened to an extra reinforcing bar 35, or to the reinforcing bar 3 which runs along the door rail, arranged at a suitable distance from the door post.
  • the hinges are then to be fastened to the iron 34, and the edging ll (Fig. 13) or I? (Fig. 14) by means of machine screws 36 inserted through this and the hinge leaf or plate 30, for whose reception threaded holes 31 are arranged in the fastening iron 34.
  • a reinforced door and hinge construction comprising a door including a pair of spaced panels, a metal reinforcing bar between and spacing said panels and recessed within the edges of said panels, a sheet metal channel-shaped cover having side and edge walls secured around the edge portions of the sides and the edge of said door, said door cover enclosing said bar with the inner surface of said cover edge wall spaced from the outer surface of said bar, the edges of said cover being inturned and embedded in said panels to seal the edge of the door, a leaf hinge having a plurality of parallel slots extending inwardly from the free edges of the door hinge to divide the leaf into a plurality of tongues, said metal cover having aligned openings in one side wall adjacent the edge wall thereof, said leaf hinge tongues being respectively inserted through said openings with the tongues sandwiched between the inner surface of said edge wall and the outer surface of said bar, and screws extending through said edge wall and said tongues and threaded into said bar.
