PATENTS FORM NO. 3 PATENTS AND DESIGNS ORDINANCE SPECIFICATION "DOOR FRAME" I, ERNST PELZ, a German Citizen and Engineer, of Gerestried/ Oberbayern, Dieselweg 10, Bundesrepublik, Deutschland DO HEREBY DECLARE the nature of this invention and in what manner the same is to be performed, to be particularly ascertained in and by the following statement :- D O O R F R A ME Abstract' of the Disclosure A door framej comprising a door case body, a door case lining, consisting of two profile members adapted to conceal the side-joints between said door case body and-, the wall forming the door opening, and a separate rabbet, bracket for the door demountably secured to said door case body, the door frame also includes corner joints for said door case lining having a bracket forming the door intrados and abuttin against the door case body, and having a mar- ■ ginal profile member disposed in angular relation to this' bracket, covering the gap between door case body and the door opening.

The Prior Art A door case lining comprising two plastic angu- · lar profiles has been known previously, one profile shank of one of the two angular profiles being developed as a rabbet bracket for the door. This rabbet bracket has the shape o a hollow body and overlaps the shank end of the second angular profile. In this formerly used door case lining, the rabbet bracket for the door is rigidly attached to an angular profile member of the door case lining, GO that this angular profile member accurately determines the depth of the door intrados on one side. Only the other angular profile can, according to this arrangement, be cut out to conform with the wall thickness, prior to the installation of the door frame, so that the rabbet bracket lug covers the joint of the two angular profiles with one j another. In addition to the previously indicated disadvantage, that in this formerly employed arrangement only one angular profile can be cut out at the time of installation,, this arrangement has the additional disadvantage that the p rofile member rigidly joined to the rabbet bracket has a relatively complicated profile, the adaptation of which with respect to diagonal alignment at the corner joints represents considerable difficulties.

Another important disadvantage to all door case linings where the rabbet bracket is rigidly joined with the door case profile, consists in that the door rabbet cannot be aligned separately from the door case lining.

This possibility of a separate alignment of door rabbet bracket and door case lining facilitates in many cases the installation of an accurately closing door.

Moreover, a significant disadvantage for door rabbet bracket and case profiles constructed in one piece can be seen in the fact that such profiles of wood can;be produced only with great expenditure of labor.

Likewise*, relatively costly tools are' required for the manufacture of such embodiments in one piece from plastics.

Another type of door case lining has been previously known, which has two L-shaped frame parts, the long profile shanks of which forra' the inner surface of the door intrados and the short profile shanks of which conceal the plaster. In this type of construction, th¾ long profile shanks are arranged in overlapping manner, so that the end of the upper long profile shank forms one rabbet bracket for the door. In this construction, the door is concisely aligned with one wall surface in the door frame, and moreover, the end of the upper long profile shank of each profile member must be worked out accurately so that a perfect cutting, prior to the installation on the building site, is not directly possible. Consequently, at least one profile, member of the door case has to be worked to exactly conform with the wall thickness, which complicates the installation of this previously known door frame. By this type of construction the rabbet, bracket, that means one end of the long shank of the upper profile member, is also constructed in one piece together with this profile member.

Furthermore, such door case linings are already known, their width conforming with the thickness of the wall and being provided with means which serve to accommodate an additional profile member which forms the rabbet bracket for the door. In this construction, the depths of the door intrados are given, and the position of the rabbet bracket in the door intrados is fixedly determined, so that no adjustment of door case lining and door rabbet bracket would be possible. Furthermore, this known door case cannot be adapted to thicknesses of the wall directly prior to the installation of· the door. However, this has been realized as an essential factor- in the practice, as with even minute deviations of the thickness of the plaster, considerable complications may occur .''during the installation of door frames. As a rule, the door frame installation is effected immediately prior to the occupancy of the house, after all of the other construction work has been completed, so that changes in the masonry walling,, cannot be made or only with considerable difficulties.

. . Objects of the- Invention An object of the invention is to produce a door frame, v'nore the door caso lining consisting of profile members which can be aligned and fitted independently of the door rabbet bracket, and where the adaptation of the door case lining to the respective wall thickness as well as the positioning of the door rabbet bracket and with this the door on the inside of the door intrados can be effected at any point chosen at random with a minimum expenditure of labor. In addition, with regard to this door frame, it can be constructed of the widest materials, as for example, of wood, plastic and the like, and, if so required, it can be cut to fit without difficulties at the construction site Itself.

Another object of the invention is the obtention of a door frame comprising: a) a door case body, b) a door case lining consisting of two profile members adapted to conceal the side-joints between said door case body and the wall forming the door opening, c) a rabbet bracket for the door, characterized in that d) said profile members of the door case lining are formed · as two angular profile brackets separately secured on said door case body, and that e) said rabbet bracket is a profile separated from said door case lining, the said rabbet bracket covering the joint between said angular profile brackets of . said door case lining attached to said door case body, ϊ and demountably secured to said door case body and' A further object of the invention is the obten- . tion in the above door frame of a corner joint for said profile members having a bracket, abutting against said door case body and a hollow profile shank arranged in angular relation to said bracket, covering the^gap between said door case, body and the wall forming the door opening, said corner joint characterized in that filler blocks are provided, which fill the space between said hollow profile shanks in the area of the corner joint and are rigidly secured to said hollow profile shanks, coupled with a bolting means pressing one of said filler blocks against the other.

A yet further object of the invention is the obtention in the above door frame of a rabbet bracket . characterized further by an elastic spring formed on said' rabbet bracket adapted to abut with slight pressure against the door edge, when the door is closed, in the rabbet bracket and/or by elastic springs adapted to abut against said door case lining in vertical relation to the door case lining plane and compressible in flexible manner.

These and other objects of the invention will become more apparent as the description thereof proceeds.

Description of the Invention These objects of the invention are fulfilled in that the profile members of the door case lining are formed as two angular profile brackets separately attached to the door case body, and in that the door rabbet bracket is separated from the case lining profiles. This door rabbet bracket covers the side-joint disposed between the two angular profile brackets of the door case lining attached to the door case body. Moreover, it is securely and de-mountably connected with the door case lining body and capable of being adjusted to the position of the door, independent of the door case lining.

Preferably the door case profile members are nailed to the door case body, this nailing being. effected close to the site of abutment chosen with regard to the desired position of the door so that the door rabbet bracket According to the invention, the door case profile members are manufactured pre erably from veneered resin fiber laminates of from several veneer layers by compressing and gluing. In this manner, a door case lining is produced, which has the pleasing and homelike appearance of wood, but which otherwise has the advantage of a simple; and accurate assembly of flat profile members, whereby the door case lining f rst ■ of all conceals the abutment of the wall to the door case body. Then, independent thereof, the door rabbet bracket can be joined through the door case lining profile member with the case body, preferably by bolting, so that the door sits accurately in the door intrados and abuts uniformly with its edges against the door rabbet bracket whe the door is closed. In the door frame of the invention, the long shank of each door case linin profile member abuts against the door case body, and the joint or abutment of the profile members of the lining as well as the fastening means of the profile members of the lining are completely covered by the door rabbet bracket, so that when the door case lining profile members are cut to the exact width, and when these profile members of the ·.·■..· door case lining are fastened, only little care has to be taken in attaching the door rabbet bracket, which facilitates substantially the assembly of the door frame according to the invention.

The door case lining profile members are attached to the door case body, they form the visible portion of the door soffit, both intrados and extrados, and conceal the joint between the door case body and the wall. The profile shank covering the joint between the door case body and the wall continues to a flat profile shank in rectangular relation to the wall plane, which shank in turn is covered by "the door rabbet bracket of the door.

Generally, two vertical profile members and one horizontal profile member are utilized for the door case lining. The latter forms the upper cross frieze of the door case lining. At the point where the vertically arranged profile: members abut against the horizontal members, the edge profile members of the door case lining, covering the Joint- between the case body and the masonry, are cut in diagonal direction, that is to say obliquely at an angle of 45° . It is difficult to join these ends of the edge profile members securely with one another. This difficulty is, in particular, encountered when these members are manufactured of wood and are nailed to a supporting base. In this case the edge profile members have to be glued together on the construction site, and since it is cumbersome to hold the glued joint under pressure while the glue is hardening, it frequently happens that the abutments do not meet accurately. Lastly, devices required to compress the parts to be glued together while the glue is hardening, are complicated and their handling is time consuming.

For this reason too, the invention encompasses , a corner joint for the door case lining profiles, which renders an accurate fitting of the oblique abutment in diagonal direction of door case profiles of the horizontal and vertical¾ edge profile members possible quickly and .easily without resorting to gluing devices.

According to the invention, blocks which fill out the space between the edge profile member of the door case lining extending as a hollow profile and the door, case body in the area of the edge joint, are glued Into the edge profile members, and these blocks which are cu to oblique abutment as with the edge profile, are securely fastened together. This fastening is preferably effected by bolting. To effect this, bores are cut in the blocks so that these bores:, in accurately abutted profile members are positioned in exact alignment in the blocks. The two filler blocks are rigidly bolted together in this position, either by a screw through the bores or,, for example, by a female screw and a nut in a groove which may be provided at the end part of the bore in one of the blocks .

Rabbet brackets for door frames of the type described in the invention can consist of a U-profile surrounding a wood ledge. This rabbet bracket has the actual door rabbet lug projecting therefrom. The object of the U-profile of the rabbet bracket is to cover the joint or abutment of the profile members which occurs in the door case lining on both sides of the door. The projecting lug of the door rabbet bracket forms the actual door rabbet which is intended to effect the sealing at the edge of the door.

It has been found to be a difficulty during the fitting, of the door rabbet brackets to dispose the projecting lug in such a manner that the edge of the door abuts simultaneously against each point of this lug. In particular, in doors made of wood, some slight unevenness may occur and finally such doors will become warped to cer-tain extent in the course of time, so that a gap will develop between the projecting rabbet lug and the door edge at various points and, consequently, the door will no longer close properly.

For a rabbet bracket according to the invention, the gaps are adjusted without trouble to a few millimeters, and beyond this, a light abutment of the door against the projecting lug of the rabbet bracket is assured in that a resilient spring is formed on the projecting lug of the door rabbet bracket. This spring in the door rabbet abuts against the door edge and executes a slight pressure on the door when the door is closed.

In order to further adjust the door opening by a few millimeters, the U-profile of the rabbet bracket can have resilient lugs extending therefrom and pressing against the door case lining whe mounted. If an adjustment is needed, a narrow strip of wood can be mounted between the door rabbet bracket having resilient lugs extending therefrom and the door case lining. By this expedient, the door width can be varied by several millimeters and the resilient extending lugs of the door rabbet bracket will extemd to give a seal between.the door case lining and the door rabbet bracket.

In the figures of the Drawings, the invention is further explained in detail. Identical parts are indicated with identical re erence numerals in all of the figures .

Figure 1 shows a sectional view through a door opening with contact to the wall, case body, door case, door rabbet bracket and door.

Figure 2 is a top view of a corner joint along the line «II-II in Figure 3* representing various elements of the joining, partly seen.

Figure 3 shows a section along the line III-III in Figure 2.

Invention, formed as flat strips and are disposed on the case body 5. The ends of the long shanks 13 and 14 of the door case profile members 8 and 9 can be cut roughly, directly prior to the installation of the door case lining 6, for example, with a hand circular saw, or with a keyhole saw, as the abutment 11 is not visible when the installation of the door is completed. In this manner the door case lining 6 of the invention can be easily and accurately adjusted to the wall thickness prior to the installation of the door 3, so that the angular ends 15 and 16 of the short shanks 18 and 19 of theprofile members 8 and 9 are closely joined to the plaster 20 of the wall 2. Daring the fitting in-: of. the doo case, the position of the door itself need not be taken into consideration, as the abutting of the rabbet bracket 7 is completely independent of the adjustment of the profile members 8 and of the door case lining 6 with regard to the door 3. After the door case lining profiles 8 and 9 are securely attached to the case body 5J the rabbet bracket or the rabbet profile 7 for the door 3 is adjusted and fastened by screws 17 to the case body through the door case lining 6. As it can clearly be perceived from the right side of Figure 1, the rabbe . profile 7 conceals the heads of the nails 10.

An essential characteristic of the invention consists in that the rabbet profile 7 is completely independent of the door profile-members 8 and 9 of the. door case lining 6. This means that the door 3 can be fitted and affixed . independently of the profiler: members 8 and '9 of the door case lining 6 and independently of the door case body 5.

Preferably the profile members 8 and 9 of the door case lining 6 are cut so that the rabbet bracket 7 covers the abutment 11 of the door case lining 6 in nearly symmetrical manner so that even in extreme cases during the f tting and aligning of the door rabbet bracket 7» this bracket ; 7 will always completely overlap the abutment 11 of the profile members Θ and 9 of the door case lining 6.

Due to these measures executed according to the invention, an accurate positioning of the door case lining 6 as well as of the rabbet bracket 7 of the door 3 is obtained in the simplest manner. It is a substantial advantage of these measures of the invention that the door 3 itself can Ό be installed at any point of the intrados chosen at random. The long shanks 13 and 14 of the profile members Θ and 9 of the door case lining 6 need to be cut for this purpose only correspondingly. Figure 1 shows a position of the door 3, wherein the door 3 is positioned accurately in the center of the door opening 1, that is, the long profile shanks 13 and 1 of the profile members Θ and 9 of the door case . lining 6 are equally long and that the intrados on both sides of the door 3 are equally wide .

As illustrated in Figures 1 to 5, the short shanks 18 and 19 of the lining profile members 8 and 9 . have a polygonal contour so that between the door case body 5 or 5' and the wall plaster 20 on the one hand, and the short shank or circular profile 19 or 191 on the other hand, a space remains which is filled out in the vicinity . of the corner joint with the filler blocks '25 or 25' of the 'invention. The edge profile member 19 or 19' covers the gap 26 between the door case body 5 or 5' and the wall plaster 20. As shown In Figure 2, a corner joint has two filler blocks 25 and 25" arranged in adjacent relation to one another along a line 27, in other words, adjusted in diagonal direction to one another. Each filler block 25 and 25' itself has a trapezoidal cross-section, as can be seen best in Figures 3 and 4. As shown in Figure 2, a hole 28 is bored through the filler block 25 and a hole 28' is bored through the filler block 25* . Both holes are arranged in a straight line if the horizontal profile 19' of the door case lining 6 and the vertical profile 19 of the door case lining 6 are accurately aligned.

A groove 22 is cut in the filler block 2 » in which a nut 23 is inserted* At the assembly, a screw 21 is introduced through the holes or bores 28 and 28' and screwed into the nut 23 in the groove 22 so that the two filler blocks 25 and 251 are tightly drawn together along the diagonal line 27 and, thereby, the horizontal and vertical profiles are rigidly attached to one another. The holes or bores 28 and 28' are.preferably measured so that the screw 21 can just about be passed through these bores 28 and 28' and has only little free play, preferably none at all in these bores 28 and 28'. Thereby an accurate alignment of the bores 28 and 28' is obtained. Preferably a bolting with a worm screw and screw nut is utilized. However, it may also be done with a wood screw, in which case, the bore 28' requires a smaller diameter in that part into which the worm thread of the wood screw is to be inserted, than this worm thread calls for. . ;j . ':·?'· As it can best be noted from Figure 2, the filler blocks 25 and 251 fill out the hollow space of the edge profile members 19 and 19 ' of the profile of the door case lining 6 only in the area of the edge joint. In the other areas of the door case lining the space between. the edge profile members 19 or 191 and the door case body 5 or 5' as well as the edge of the plaster 20 remains preferably free. The filler blocks are usually glued into the edge profile members 19 and 19 ' , but they can also be screwed in or riveted on the profile members.

To obtain a perfectly smooth joint of the edge profile members 19 and 191 at the joint abutment, as illustrated in Figures 4 and 5, a tongue 35 can be inserted in the front surfaces of the edges of the edge profile members 19 and 19 these edges abutting against one another along the line 27.

As it is evident in Figure 4, for this purpose a groove 36 is mill cut into the front surface. Of course, this groove is not only milled into the horizontal profile member 19 ' shown in Figure 4, but also into the vertical profile member 19, so that the tongue 35 will assume the position illustrated as dotted lines in Figure 5.

To accurately join the door intrados profile shanks 14 and 141 of the profile members Θ and 9 also on the corner, according to the invention as shown in Figure 5, a groove 37 can be milled into the vertical door case body member 5, the said groove taking in the entire width of the door case body 5 and directly abuttin against the horizontal frieze of the door case body 5' . The edge of the profile shank 14' of the horizontal profile is extended at 38 and inserted into this groove 37 as illustrated. The profile shank 14 of the vertical profile is cut off exactly rectangularly so that it abuts bluntly against the horizontal profile shank 14'· This offers a perfect Joint abutment at the corner.

In Figure 6, a door mounting is shown where the profile members 8 and 9 are applied, for example, nailed to the door case body 5. The abutment 11 formed between the profile members 8 and 9 is covered by the door rabbet bracket 7· This door rabbet bracket 7 has a U-profile 5 and a rabbet lug 46 extending therefrom. The U-profile is filled, as illustrated, with a wooden strip 47 and the rabbet profile 7';is secured to the case body by means of a screw 48 (similar to screw 17 in Figure 1). The rabbet lug 46 forms the door rabbet proper. According to this invention, an Inverted elastic tip 39 is formed on the lug 46 which can be flexibly pressed against the part 4l of the lug 46 in the direction of the arrow 40. When the edge of the door strikes against the tip 39 of the lug 46, the said lug is pressed in a smooth and elastic manner onto the part 41, thereby sealing the edge of the door. Furthermore, the tip 39 adjusts to give a small gap between the door and the rabbet lug 46.

Figure 7 illustrates a type of construction, by means of which it is possible to adjust deviations of the door width to the extent of a few millimeters . The U-profile 4 for the door rabbet bracket 7 in Figure 7 differs from the exemplified embodiment of Figure 6, in that the edges 53 and 5 of the rabbet bracket 7» which, when affixed abut against the door case profile members 8 and 9, are formed in vertical relation to the door case surface in elastlcally compressible manner. This elastic compressibility is attained, for example, by resilient lugs 55 and 56 which are formed on the extremities of the rabbet bracket 7. By utilizing a small intermediate block 57, the door width can be varied by several millimeters on each side, depending on the width c the intermediate block 57· The. >precedlng speci ic embodiments are illustrative of the practice of the invention. It is to be understood, however, that other expedients known to those skilled in the art may be employed without departing from the spirit of the invention or the scope of the appended 'claims. .·' ν. ■·;.··.: ■ ·;:':■·. :. .·' ,· '·· : :·· ·¾;,!¾
