DOOR CONSTRUCTION Filed Jan. 4, 1965 744 r if 1 .7 MW/775% twig INVENTOR F76 5 HOMER a. WEI NT United States Patent 3,286,424 DOOR CONSTRUCTION Romer G. Weyant, 81 Edgewater Drive, Elkhart, Ind. Filed Jan. 4, 1965, Ser. No. 423,178 3 Claims. (Cl. 52-291) This invention relates generally to improvements in the construction of doors, and more particularly to exterior doors that must be straight and true relative to the door jamb to provide a good weather seal.

A good weather seal is highly desirable with exterior doors, particularly with doors used in house trailers, and the like. One door used in house trailers generally comprises a frame on which front and rear panels are mounted. The panels may be made of wood or sheet metal. One side edge of the door is hinged on a side jamb to open into the trailer. Weatherstripping is fastened on the hinged side jamb, the head jamb and the other side jamb to weather seal the top, and the hinged and unhinged sides of the door when the door is closed. Weatherstripping may also be provided along the bottom of the door or on the threshold.

One problem faced in the manufacture and use of such doors is to assure that a proper weather seal is provided initially and that the seal can be maintained with use. A good seal along the hinged side of the door can be assured when the door is hinged. A good seal for the three unhinged edges can be obtained initially by manufacturing the door and the jamb to be straight and true. However, in the industry a guaranteed straight door within prescribed manufacturing tolerances may be straight and true to within one quarter of an inch. This tolerance is too great for house trailer doors and the like where a weather seal along the unhinged edges is of the utmost importance, particularly with wide doors which are not protected by a canopy or an awning. Thus it is desirable to provide a door that is straight and true to within less than one quarter of an inch. This tolerance is not commercially practical with conventional door constructions and a slight warp or camber in the jamb will impair the weather seal. Sheet metal panel doors present an even greater problem. A temperature difference between the front and rear metal panels may be as high as 50 or 60. The outside sheet metal will contract with respect to the inside panel to warp or camber the door and thus impair the weather seal. Thus it is desirable to adjust the camber in the door in directions inwardly and outwardly of the plane of the door so that the door may be made straight and true for a jamb that is straight and true or selectively bent to conform to a warped door jamb.

The object of this invention is to provide a door whose camber is adjustable in directions both inwardly and outward of the plane of the door by a construction that is simple and economical to manufacture; that provides a door that is straight and true; that simplifies initial installation and later adjustment to a warped door jamb; and that does not detract from the appearance of the door.

Further objects, features and advantages of this invention will become apparent from a consideration of the following description, the appended claims, and the accompanying drawing in which:

FIGURE 1 shows an exterior door constructed in accordance with the present invention and hinged on a jamb to swing in an inwardly direction;

FIGURE 2 is an enlarged view of the right side of the door as viewed in FIG. 1 with portions of the door broken away to illustrate a vertical frame member and one of a pair of tension rods for adjusting the camber of the door in accordance with the present invention;

FIGURE 3 is a vertical section taken on the line 3-3 of FIG. 2 with a portion of the jamb also shown to illustrate the pair of tension rods disposed adjacent front and rear faces of the door.

FIGURE 4 is a fragmentary horizontal section taken along the line 44 of FIG. 2 with a portion of the jamb also shown to illustrate an upper threaded end on each of the tension rods together with a washer and a nut for selectively tensioning the rods; and

FIGURE 5 is a horizontal section taken along the line 55 of FIG. 2 to illustrate out-of-round heads on the lower end of each of the rods to prevent rotation of the rods when the tension in the rods is adjusted.

Referring to FIG. 1 a door jamb 10 is illustrated as having a pair of vertical side jambs 12 and 14 and a top or head jamb 16. An exterior door 18 is hinged along one side 19, the left side as viewed in FIG. 1, on jamb 12 to swing inwardly, as for example, to open into a room in a trailer. lambs 14, 16 are fashioned with lateral stops 20, 21 (FIGS. 4 and 3), respectively, that face inwardly toward door 18. Door 18 fits closely in jamb 10 so that a good weather seal can be provided between head jamb 16 and a top edge 22 of door 18 and between an unhinged side edge 24 and side jamb 14. A bottom edge 26 on the door 18 is arranged to fit closely with a threshold 28.

Referring to FIGS. 2-5, door 18 generally comprises a front panel 30 and a rear panel 32. Panels 30, 32 may be made of wood or sheet metal. A wooden frame mem ber 34 extends vertically between the front and rear panels 30, 32 from the top edge 22 to the bottom edge 28 and directly adjacent side 24 of the door 18. Panels 30, 32 may be glued directly on opposite faces of frame member 34. A notch 35 is cut in the top corner of member 34 adjacent side 24 to form a fiat horizontal face 36. A notch 37 is cut in the bottom corner of member 34 adjacent side 24 to form a flat horizontal face 38. A longitudinal groove 40 is formed in a front face of the member 34 adjacent panel 30. A groove 42 is formed in the opposite face of member 34 adjacent panel 32. Grooves 40, 42 extend vertically between faces 36, 38 of notches 35, 37. A front tension rod 44 is disposed in groove 40 and the rear tension rod 46 is disposed in groove 42. Each of the rods 44, 46 has a head 48, 50 at its lower end and a nut 52, 54 threaded on its upper end. Heads 48, 50 are generally rectangular to engage each other and prevent rotation of rods 44, 46. Disposed between nuts 52, 54 and the face 36 of notch 35 is a flat plate or washer 56, 58, respectively.

A wooden block 60 is disposed in notch 35 and releasably secured to member 34 as by screws 62. Block 60 has a recess 64 to accommodate the upper end of rods 44, 46 together with nuts 52, 54 and washers 56, 58. Similarly a block 66 is disposed in notch 37 and is releas-. ably secured to member 34 as by screws 68. Block 66 has a recess 70 to accommodate heads 48, 50 of rods 44, 46.

By way of illustration two different types of weatherstripping are shown in FIGS. 3 and 4 as being useful with a door constructed in accordance with the present invention. The Weatherstripping may be in the form of metal strips 74, (FIGS. 3 and 4). One edge of strip 74 is fastened to the inner periphery of head jamb 16. One edge of strip 75 is fastened to side jamb 14. Strips 74, 75 have free edges that engage the respective top edge 22 and side edge 24 of door 18. Alternately the Weatherstripping may be plastic beading 76 fastened on stops 20, 21 to abut panel 30 adjacent top 22 and side 24. With either form of Weatherstripping the tension in rods 44, 46 can be adjusted to make door 18 straight and true or to conform door 18 to a warped jamb and thus assure a good seal between the door and the weatherstripping.

The tension in rods 44, 46 can be adjusted selectively by tightening or loosening nuts 52, 54 to straighten member 34 and thus door 18 along edge 24 or to camber member 34 and thus door 18 to conform to a warped jamb. For example increasing the tension in rod 44 and relieving the tension in rod 46 bows the top and bottom of member 34 and thus door 18 in a direction toward the left as viewed in FIG. 3. On the other hand by increasing the tension in rod 46 and relieving the tension in rod 44 the top and bottom of member 34 and thus door 18 are bowed in a direction to the right as viewed in FIG. 3. By adjusting rods, 44, 46 door 18 can be held fiat by rods 44, 46 or cambered to conform to a warped jamb and thus assure a good weather seal.

In manufacturing door 18 the tension in rods 44, 46 is set at the factory by adjusting nuts 52, 54 to make door 18 straight to within less than one quarter of an inch along edge 24. Blocks 60, 66 are then fastened in place. Door 18 can be made straight to within less than one quarter of an inch along edge 19 when the door is fastened on side jamb 12. If head jamb 16 and side jamb 14 are straight and true a good weather seal between door 18 and the Weatherstripping is achieved. However if door 18 has warped prior to installation, block 60 can be removed and the tension in rods 44, 46 can be adjusted to straighten door 18 along edge 24. If the side jamb 14 or head jamb 16 is warped the tension in rods 44, 46 can be adjusted to conform the door to the warped jamb.
