Description

adapter profile

The invention relates to an adapter profile for a door frame according to the features in the preamble of claim 1, a door frame according to the features in the preamble of claim 8 and a door according to the features in the preamble of claim 11.

In conjunction with the door leaf, door frames serve as the closure of building openings in building walls into which the door frames are permanently installed. Door frames made of wood and / or wood-based materials usually have a decorative cladding angle, a lining board unit and a folded cladding angle. On each of the two sides of the wall facing away from each other, the edges of the building opening are covered by the decorative cladding angle or the folded cladding angle, these being fastened to the lining board unit which forms the middle part of the door frame and extends over the thickness of the wall inside the building opening extends. The rabbet cladding angle and the decorative cladding angle are each connected to the lining board unit via a tongue and groove connection, the connection of the decorative cladding angle to the lining board unit only taking place after the installation of the lining board unit in the building opening. The rebate cladding bracket also serves to hold the hinges for the rotatable fastening of the door leaf and the locking devices for the door leaf. It is also known to trim trim,

To manufacture the rabbet cladding bracket and the lining board unit as separate components that can be connected to one another at the construction site, and also for the subsequent sheathing of a frame that is already connected to the building structure or the building wall, e.g. a frame made of steel or solid wood.

Door frame systems are also known, in which an adapter profile is provided between the lining board unit and the rabbet cladding angle, to which the lining board unit and the rabbet cladding bracket are fastened. In a known embodiment - according to DE 34 44 255 AI - a metal profile with at least one longitudinal groove for receiving a frame board and a sealing profile is provided, with one

Base plate of the metal profile legs are arranged, which form longitudinal grooves, and wherein the longitudinal grooves serve to accommodate the rabbet cladding angle and a sealing profile on the one hand and the accommodation of the lining board unit on the other. The described technical The solution is based on the task of creating a metal profile for a door frame and a door frame constructed using this metal profile, by means of which it is possible to clad old door frames quickly and easily, but nevertheless a reliable fit and a good seal of the in the frame to be picked up door should be reached. However, it is disadvantageous that in this door frame system there are separate embodiments for the lining board unit and the rabbet cladding angle and in particular no lining board units and rabbet lining bracket that can be connected to one another by means of tongue and groove connection even without an adapter profile can be used.

As in many areas of mass-production products, the trend can also be observed in the production of doors or door frames, using the most uniform or standardized individual components possible to produce the widest possible range of different design variants of products. For some time now, efforts have also been made to produce door frames with a fold depth that has been increased to such an extent that door leaves with a thickness as previously used can be attached, the door leaf not over the front side of the rebate cladding angle or over the door frame protrudes and, if possible, lies in one plane with the end face of the folded cladding angle. Accordingly, it is provided that door leaves, which preferably have no fold, are used. This enables an easier one

Structure of the door leaves.

The object of the invention is to provide an adapter profile for a door frame, with which it is possible to produce door frames with an increased rebate depth. Furthermore, it is an object of the invention to create a door consisting of a door leaf and a door frame, in which the door leaf can be attached in such a way that it does not protrude beyond the door frame.

The object of the invention is achieved by an adapter profile according to the features in the characterizing part of claim 1. The advantage here is that, by using the adapter profile according to the invention, lining board units and rebate cladding angles which are used as standard and which can be connected as such by a tongue and groove joint, are used for a new design of door frames with an enlarged or variable rebate depth can be. The further developments according to claims 2 and 3 are also advantageous, since this results in greater stability or rigidity of a door frame constructed from a lining board unit, an adapter profile and a rabbet cladding angle. A correspondingly constructed door frame has a greater rigidity in the area of the adapter profile than a door frame which, as standard, is made up only of a lining board unit and a rabbet cladding angle.

The design of the adapter profile according to claim 4 offers the advantage that a greater stability or rigidity of the connection between the feed board unit and the adapter profile can be achieved.

The development according to claim 5, wherein the side surfaces of the legs of the adapter profile are formed with a surface roughness, the advantage is achieved that after joining the adapter profile with a corresponding rabbet cladding angle on the one hand and a lining board unit on the other hand by pressing in the corresponding

Leg in the corresponding grooves a higher strength of the connection of the respective connection points is achieved.

By developing the adapter profile according to claim 6, it is possible to manufacture door frames or doors that have efficient fire protection.

The development of the adapter profile according to claim 7, in which the material of the adapter profile made of plastic, wood or wood-based material, such as Wood extrudate, or metal, has the advantage that known processes, such as extrusion or extrusion, can be used to produce profiles in the most uniform possible quality over the length of the adapter profile.

The object of the invention is achieved independently by a door frame, according to the features in the characterizing part of claim 8. The additional use of the adapter profile according to the invention in combination with a decorative panel angle, a rebate panel angle and a lining board unit has the advantage that a door frame with an increased rebate depth is produced compared to door frames, which as standard consist of only one trim panel angle, one rebate panel angle and one panel board unit can. By using the adapter according to the invention terprofils, it is thus possible to produce door frames with different rebate depths using rebate cladding angles and lining board units of the same external shape and dimensions.

The design of the door frame, according to claim 9, by providing press fits for mutually corresponding grooves and legs of the adapter profile and the lining board unit on the one hand and the adapter profile and the rabbet cladding angle on the other hand, achieves the advantage that the corresponding parts are used without the aid other means that can be firmly connected. Usually, the rabbet cladding angle and the lining board unit are connected to one another by gluing or gluing, the parts being held together by applying a contact pressure during the period of hardening of the adhesive or glue. A corresponding design of press fits achieves the advantage that no press pressure has to be applied during curing.

In the exemplary embodiment of the door frame according to claim 10 it is provided that the

A sealing profile is fastened to the end face of the lining board unit facing the rabbet cladding angle. This has the advantage that, in cooperation with a door leaf attached to the door frame, the fold between the door frame and door leaf can be adequately sealed. The sealing profile consists of a relatively easily elastically deformable material and is dimensioned so that it is slightly compressed when the door leaf is closed and is therefore under an internal prestress that increases the sealing effect. The fact that the sealing profile is designed in such a way that it covers the end face of the first end region of the adapter has the advantage that the adapter profile is not visible and can therefore be used for door frames with different surface properties as well as wood types or colors without the overall visual impression to influence or impair.

The object of the invention is achieved independently by a door according to the features in the characterizing part of claim 11. The use of a door frame according to the invention in combination with a door leaf has the advantage that, due to the greater rebate depth, doors can be manufactured using door leaves with a simpler structure, in particular door leaves without a profiled edge. The further developments according to claims 12 and 13 are also advantageous, since doors with a door leaf that does not protrude beyond the rebate cladding angle can thereby be produced. The flat finish of the door leaf with the rebate cladding angle also achieves an overall more compact appearance of the doors.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

The door frame 3 has, as a central part, a lining board unit 6 which covers an inside 7 of the building opening 2 over almost the entire area of a wall thickness 8 of the building opening 2. On an end region of the lining board unit 6 facing away from the door leaf 5, a decorative cladding bracket 9 is fastened thereon. In one

An end cladding bracket 10 is fastened to the end region of the lining board unit 6 facing the door leaf, an adapter profile 11 according to the invention being arranged between the lining board unit 6 and the folding cladding bracket 10. At this point, it should be particularly pointed out that the lining board unit 6 and the fold cladding bracket 10 are components which are used as standard and which are also arranged without them

Adapter profile 11 can be connected to one another by tongue and groove connection. A rebate depth 12 of the door frame 3 is determined by the distance between an end face 13 of the rabbet cladding bracket 10 facing away from the lining board unit 6 and an end face 14 of the rabbet board unit 6 facing the rabbet lining bracket 10. Due to the arrangement of the adapter profile 11 between the rabbet cladding bracket 10 and the lining board unit 6, the door frame 3 has the rabbet depth 12, which is standard compared to a rabbet depth 12, i.e. without adapter profile 11, trained door frames is enlarged. The rebate depth 12 of the door frame 3 is greater than a thickness 15 of the door leaf 5. According to this exemplary embodiment, it is provided in particular that the front side 13 of the rabbet cladding bracket 10 facing away from the lining board unit 6 and one side 16 of the door leaf facing away from the lining board unit 6

5 are at least approximately in one plane. This means that the end face 13 of the rebate cladding bracket 10 and the side 16 of the door leaf 5 are approximately flat. A sealing profile 17 is also fastened to the end face 14 of the lining board unit 6 facing the rabbet cladding angle 10, so that the door leaf 5, with a side 18 facing the lining board unit 6, bears against the sealing profile 17 in the closed position of the door leaf 5, thus ensuring an adequate seal ,

Fig. 2 shows an enlarged detail of the door 1, consisting of the door frame 3 and the door leaf 5 cut, according to Fig. 1. The adapter profile 11 consists of a connecting web 19 with a first side 20 and a second side 21, at the first page a first

Leg 22 and a second leg 23 are formed on the connecting web 19 such that the two legs 22, 23 are aligned parallel to one another and thus form a groove 24. On the second side 21 of the connecting web 19, a leg 25 is formed, the Leg 25 is aligned parallel to the two legs 22, 23 of the first side 20 of the connecting web 19.

A side surface 28 of the first leg 22 facing away from the groove 24 and an end surface 29 of a first end region 30 of the connecting web 19 form a common surface or lie at least approximately in one plane. However, it is also possible for the side surface 28 of the first leg 22 to be arranged laterally offset with respect to the end surface 29.

The leg 25 on the second side 21 of the adapter profile 11 is laterally offset with respect to the first end face 29. The lateral offset is dimensioned such that a distance 100 between the first end face 29 and a side face 37 of the leg 25 is equal to a thickness 101 of the first leg 22 on the first side 20.

On a second end region 31 of the connecting web 19 opposite the first end region 30 and on a side surface 32 of the adjacent end region 31

Leg 25 of the second side 21 is integrally formed with a stiffening element 33, this having a leg 35 on an end region 34 pointing in the direction of the leg 25 of the second side 21, or this leg being integrally formed on the stiffening element 33. This leg 35, like the leg 25, is aligned parallel to the two legs 22, 23. The side surface 28 and an opposite side surface 36 of the leg 22, the

Side surface 32 and a side surface 37 of leg 25 opposite this, as well as side surfaces 38 and 39 of leg 35 and a side surface 40 of leg 23, can additionally be formed with a structured surface or with a surface roughness.

3 shows a door 1, consisting of a door frame 43 and a door leaf 44, according to the prior art. In contrast to the door frame 3, according to FIGS. 1 and 2, the door frame 43 does not have the adapter profile 11. The feed board unit 6 is of the same design as in the exemplary embodiment of the invention, according to FIGS. 1 and 2. In contrast, the feed board unit 6 and the rabbet cladding angle 10 directly via a groove and

Spring connection connected to each other. The distance between the end face 13 of the rabbet cladding bracket 10 and the end face 14 of the lining board unit 6 determines a rebate depth 45 which is smaller than the rebate depth of the door frame 3, according to FIGS. 1 and 2. Use of the door leaf 44 with the same thickness 15 as in the door leaf 5, according to FIGS. 1 and 2, in contrast, it is now also not possible for the door leaf 44 to end flush with the end face 13 of the rabbet cladding angle 10. Accordingly, a fold 46 is also provided for the door leaf 44.

FIG. 4 shows a further exemplary embodiment of a door 1 according to the invention, represented by a horizontal section in the region of a door hinge 47. The door hinge 47, according to this exemplary embodiment, has tabs 48 and 49, the tab 48 on a rabbet side 50 of the rabbet cover bracket 10 and the tab 49 is fastened to a rabbet side 51 of the door leaf 5. The attachment is carried out by screws 52 and 53, each of which is directed perpendicular to the fold side 50 of the fold cladding bracket 10 or to the fold side 51 of the door leaf 5. A reinforcement bracket 54 is additionally provided in the region of the door hinge 47 in order to increase the fastening security. The reinforcement bracket 54 is designed such that it is joined around a leg 55 of the adapter profile 11 in a first end region and the screws 52 extend through the reinforcement bracket 54 in a second end region or are additionally fastened in this. The door 1 according to this exemplary embodiment simultaneously offers the advantage that the side 16 of the door leaf 5 is flush with the end face 13 of the rebate cladding bracket 10 and that the fastenings of the tabs 48, 49 on the door frame 3 or on the door leaf 5 are covered, i.e. is hardly visible from the outside. Reinforcement elements in the form of a reinforcement angle 54 can advantageously also be used at other locations, such as in the area of the striking plate. The reinforcement angle 54 is preferably made of metal, such as e.g. Steel.

With an adapter profile 11, according to the exemplary embodiments as described in FIGS. 1, 2 and 4, a door frame 3 for a door leaf 5 with a trim panel angle 9, a rabbet panel angle 10 and a lining board unit 6 can be produced, the folding panel angle 10 and the lining board unit 6 are connected in the manner described with an adapter profile. It is further provided that a groove 56 on an end face 14 of the lining board unit 6 facing the rabbet cladding angle 10 and the first leg 22 of the adapter profile 11 located in this groove 56 are formed with an interference fit and the groove 56 and this leg 22 of the adapter profile 11 at least are connected to one another by pressing or that a groove 57 in one of the feed board unit 6 facing end face 58 of the fold cladding bracket 10 and the leg 25 of the adapter profile 11 located in this groove 57 are formed with an interference fit and the groove 57 and this leg 25 are connected to one another at least by pressing. In addition, however, as an alternative to the press fit of the groove 56 and the leg 22 and the groove 57 and the leg 25, it is of course also possible to achieve a fastening by another type of connection, such as gluing. On the other hand, the formation of press fits has the advantage that when the parts are connected by gluing while the adhesive or glue is curing, the parts do not have to be held together by applying a pressing force.

The adapter profile 11 according to the invention can be made of materials such as e.g. Wood or a wood material, plastic or metal. The adapter profile 11 is advantageously produced from wood extrudate.

In the exemplary embodiments of the door frames 3, lining board units 6 and rabbet cladding brackets 10, which can be connected to one another by a simple tongue and groove connection, are described, i.e. the feed board unit 6 has only one groove 56. Accordingly, the adapter profile 11 has the leg 22 on the first side 20 and the leg 25 on the second side 21 of the connecting web 19. However, embodiments of an adapter profile according to the invention are also adapter profiles 11 for feed board units 6 and rabbet cover bracket 10, wherein not only one groove 56 but also two or more grooves for connection to the rabbet cover bracket 10 are formed in the side 14 of the lining board unit 6 facing the rabbet cover bracket 10. Accordingly, a corresponding adapter profile 11 is formed with one or more legs 23 on the first side 20 and likewise with one or more legs 25 on the second side 21 of the connecting web 19, which are each aligned parallel to the leg 22.

In a further exemplary embodiment of the adapter profile 11, it is provided that a fire protection element 59 is formed in the first end region 30 of the connecting web 19, and as close as possible to the end face 29. This fire protection element 59 consists of a refractory foaming agent, the volume of which is multiplied by exposure to heat from a temperature of approximately 100 ° C. This temperature-indicated expansion of the fire protection element can ensure that the material of the adapter profile is rich the end face 29 is broken open and the foam of the expanding fire protection element 59 causes a seal of the door rebate. In the case of producing the adapter profile from wood extrudate, it is possible, for example, to co-extrude the fire protection element 59 at the same time.

For the sake of order, it should finally be pointed out that for a better understanding of the structure of the adapter profile or the door frame as well as the door, this / these or its / its components have been partially shown to scale and / or enlarged and / or reduced.
