United States Patent 3,501,866 REPLACEMENT DOOR AND FRAME UNIT Waldo 0. Johnson, Wooster, Ohio, assignor to Georgia- Pacific Corporation, Portland, 0reg., a corporation of Georgia Filed Oct. 18, 1968, Ser. No. 768,677 Int. Cl. E06b 1/22 US. Cl. 49-380 4 Claims ABSTRACT OF THE DISCLOSURE The replacement door and frame unit includes a pair of side jamb strips to be positioned in rabbets formed in the side jambs of the door frame and usually resiliently positioned to be urged laterally inwardly of the door frame. Resilient sealing means are carried on the laterally inner face of the side jamb strips and a door is hingedly secured to one of such strips for extending therebetween.

The present invention relates to a replacement door and frame unit of the type that can be positioned in an existing door frame of conventional construction after the original door has been removed therefrom.

Frequently it is desired to improve present old building units and to replace the doors provided in such old buildings. Usually this has required some appreciable carpentry work wherein a door must be cut to special size and then is must be adapted specifically to the shape of a door frame which may have warped in use or which may have settled on one side thereof or which may have become out of square for any of a number of reasons.

The general object of the present invention is to provide a new and improved precut and preformed replacement door and frame unit that is adapted to be attached to an existing door frame with a minimum of assembly and installation work. Another object of the invention is to provide a replacement door and frame unit which can be attached to an existing door frame and fit therein, even though the original door frame has become slightly out of square in service and to provide a complete door and hinge and door locking means as one unit that can be readily assembled into and adapted to the size of an existing door frame which has had the original door removed therefrom.

Other objects and advantages of the invention will be made more apparent as the specification proceeds.

In general, the present invention relates to a preformed door which is initially hingedly secured to one of a pair of side jamb strips that are adapted to be positioned in rabbets formed in the original side jambs of a door frame. Preferably these side jamb strips are resiliently positioned and are urged laterally inwardly of the door jamb and resilient sealing means are carried on the laterally inner faces of the side jamb strips for contact with the door positioned in the replacement unit. The door replacement unit also may comprise a new threshold strip and a top header strip to be attached to the original door frame.

Attention now is particularl directed to the drawings, wherein:

FIG. 1 is a fragmentary broken away vertical section of a replacement door and frame unit of the invention shown in assembled, operative position;

FIG. 2 is a fragmentary horizontal section taken through the replacement door unit and, associated door frame of the structure shown in FIG. 1; and

'ice

FIG. 3 is a fragmentary elevation of a portion of the assembly of a door hinge.

When referring to corresponding members shown in the drawings and referred to in the specification, corresponding numerals are used to facilitate comparison therebetween.

Attention now particularly is directed to the details of the structure shown in the drawings, and a door frame indicated as a whole by the numeral 1 is shown and a replacement door and frame unit is provided for attachment to the door frame indicated as a whole by the numeral 2.

FIG. 2 of the drawings shows that a pair of side jambs 3 and 4 are provided in the door frame 1 and that each of these side jambs has its outermost end on the laterally inner surface thereof provided with a rabbeted section or rabbet 5 and 6, respectively. Normally, the door frame 1 includes a threshold 6a and a top or header strip 7. The header strip 7 has a rabbet 8 formed in the lower outer corner thereof as is conventional in most door frames for receiving the original door attached in the door frame 1 to be positioned in the rabbeted portions 4, 5 and 8 provided in the door frame.

This new replacement door and frame unit 2 includes a door 10 which maybe of any suitable construction and usually is made of metal or a metal clad wooden door. It is secured, as by a plurality of vertically extending hinges 11, to a side jamb strip 12 that is positioned in the rabbet portion 4 of the side jamb 3. A similar or equivalent side jamb strip 13 is provided in the opposite side jamb 4 likewise adapted to be received within the rabbeted section 6 provided therein. lreferably in positioning the side jamb strips in or on the side jambs 3 and 4, some type of a resilient back-up means is provided intermediate the side jamb strip and the associated portion of the side jamb. Thus, in this instance, elongated leaf springs or a plurality of coil springs 14 are positioned behind the side jamb strips 12 and 13 at vertically spaced portions thereof, and then attachment means, such as screws 15, extend through the individual side jamb strips, and the springs 14 to engage adjacent portions of the side jambs, whereby loosening or tightening the springs 14 will adjust the side jamb strips to receive the door 10 and position it in desired relationship to the remainder of the door and frame unit 2. Initially, the side jamb strips can be cut to proper length at their lower ends if originally made of greater than the door frame opening height, but a preformed beveled top corner joint need not be varied.

To aid in obtaining a sealed joint or connection between the side jamb strips and the door 10, preferably vertically extending, resilient plastic sealing strips 16 are carried by each of the side jamb strips 12 and 13. Preferably these strips 16 have enlarged or beaded vertically extending edges 17 and 18 which are positioned under or in undercut grooves or recesses 19 and 20 formed in each of the side jamb strips and extending the height thereof adjacent the lateral margins thereof whereby the strips 16 are adapted to be compressed slightly and inserted or be threaded into the grooves 19 and 20 to take the convex shape on their laterally outer surfaces as indicated in FIG. 2. The strips 16 may be made from a vinyl resin or other suitable material and naturally will protrude some from the adjacent faces of the side jamb strips and be in resilient engagement with opposed lateral margins of the door 10.

To provide a finished appearance for the replacement door and frame unit 2 of the invention, preferably a pair of vertically extending stops 21 and 22 each of which has an edge portion substantially parallel to the plane of the door are so secured to the side jambs 3 and 4 as to have edges positioned immediately adjacent the door 10 to abut thereagainst when closed. Usually flexible magnetic sealing strips 60 of conventional composition are positioned in engagement with contoured recesses 61 formed in the stops 21 and 22 to engage the door. These stop strips 21 and 22 are secured in place in any conventional manner, as by screws 23.

Preferably a top liner strip is also provided in the replacement unit and such top strip is adapted to be secured to and be positioned in the rabbet 8 formed in the header 7. In this instance, a plurality of elongate flat leaf springs 31 are positioned intermediate to the top strip 30 between it and the adjacent portion of the header 7. However, it will be realized that any resilient means can be used to position the top strip 30 in adjustable relation to the adjacent header 7. Again, the top strip 31 positions a resilient sealing strip 32 therein in the same manner as the strips 16 are positioned and a top stop 33 with a magnetic strip 66 therein likewise is preferably secured to the header 7 immediately adjacent the top edge of the door 10.

In the bottom portion of the door and frame unit 2, preferably an adjustable threshold unit 35 is provided. This unit 35 includes a bottom plate 36 which is suitably attached to the threshold 6a and telescopically receives a bottom or cover strip 37 in telescopic relation whereby an attachment screw or screws 38 can secure this cover strip 37 to the bottom plate and be adjusted or forced vertically downwardly into the bottom unit 36 by the screws 38 to compensate for any possible irregularities in the threshold 6a or its relationship to the remainder of the door frame. The door 10 also carries a resilient plastic bottom sealing strip 39 which is in preferably telescoped engagement with a bottom plate 40 positioned on the lower edge of the door 10 whereby the sealing strip 39 extends resiliently downwardly and will be in flexible or compressed engagement with the cover strip 37 when the door is closed. Usually such strip 37 has a little flexible plastic sealing strip 41 in telescopic engagement therewith and flexibly extending over the margins of the strip 37 and a channel portion 42 of the bottom unit 36 in which the top strip 37 is resiliently positioned to aid in providing a good seal between these two relatively movable members.

While not completely shown in the accompanying drawings, it is another feature of the invention that the door 10 will have a suitable latch' and/or lock means suitably attached thereto or the door 10 is made to receive the lock means when the unit 2 of the invention is made and which latch or lock member is adapted to engage with a suitable keeper means or strike plate 63. Such strike plate is provided on a portion of the side jamb strip 13 where the cover strip 16 is removed and the flanges of the trips are removed, usually, as at the hinge areas so that no adjustment of the lock means is required by the person assembling the door and replacement unit in the door frame 1.

It should be noted that each of the side jamb strips 12 and 13 have edge flanges 12a and 13a thereon which are adapted to be in telescopic engagement with an adjacent edge portion of the side jambs 3 and 4 and with the stop strip 30 likewise having an edge flange 30a whereby adjustment in position of these members may be made without exposing any of the rabbeted portions of such sections of the door frame 1. It also should be noted that the resilient sealing strips 16 and similar means used in the door are positioned over the heads of the screws 15 used to position these members in the door frame whereby a neat attractive finished overall appearance is provided. The resilient strips 16 are readily removable from association with the remaining portions of the door and frame unit 2 so that the side jamb strips can be readily adjusted in position, if desired. Resilient sealing strips 64 with an adhesive surface layer thereon are carried by the stops 21 and 22, as shown. A similar resilient strip is normally carried by the stop strip 33.

The hinges 11 normally are riveted as at 71 to the side jamb strip 12 at locations where the vertically extending overhanging edge flanges 72 and 73 thereof are removed. Then screws can be used to attach the hinges and side jamb strip to the side jamb 3 through the remaining holes in the hinge plates. But the hinges are preassembled to the side jamb strip and/ or to the door 10.

From the foregoing, it is believed that a novel and improved replacement door unit has been provided. This replacement unit can be provided complete and with sufficient adjustment being provided in the side jamb strips 12 and 13 and in the positioning of the top strip 30 whereby the replacement unit will readily adjust to and cover the portions of the door frame 1 in a neat manner for effective mounting of the door and frame unit 2. The various side jamb strips 12 and 13, stops 21 and 22 and other parts of the replacement door frame preferably are made from a metal such as aluminum by extrusion thereof to the contour or section desired. The frame components can be preassembled or be assembled on the job, as desired, and be installed rapidly and easily by relatively unskilled workers. But, an improved appearance sealed door unit is provided. Thus, it is believed that the objects of the invention have been achieved.
