EP3228794B1 - Profile for frames of doors, wall elements or windows - Google Patents

Description

The invention relates to a profile for frames of doors, wall elements or windows.

Known profiles include an upper part and a lower part, which are usually designed as a cavity profile. For thermal insulation upper part and lower part are usually connected to each other by means of insulating webs made of a plastic. It is also known to improve the insulating properties of the composite profile to equip the insulating bars with transverse surfaces, which reduce heat losses through convection and heat radiation, such as in the DE 295 20 444 U1 or EP 2 256 280 A2 shown. From the EP 1 510 643 A1 is a profile for frames of wall elements, doors or windows with a top and a base known. Upper part and lower part are connected via side walls with each other, wherein the side walls are inclined de webs, which reduce heat conduction.

However, such composite profiles are not suitable for fire protection applications, since the plastic insulating bars in a fire led to the failure of the composite profile. However, the formation of solid composite profiles of metal is not desirable for weight, energy and cost reasons.

It is therefore an object of the present invention to provide a profile of the type mentioned, which avoids the disadvantages of the known and in particular a simple and flexible training of a profile which is adaptable to the particular needs, suitable for fire protection applications and inexpensive to produce allowed.

The object is achieved with a profile according to the characterizing part of the independent claim.

The inventive profile comprises an upper part and a lower part, each with an outer wall. Upper part and lower part can but also be designed differently. Upper part and / or lower part may be formed, for example, as a cavity profile. Alternatively, the upper part and / or lower part can consist of a solid profile. Also conceivable are composite profiles with a profile part made of a metal, which is provided with a wooden, stone or plastic cover which form the outer wall. As the metal for the upper part and / or lower part and / or profile part, for example, steel, stainless steel, aluminum, Cortenstahl, brass and copper come into question. Metals and / or alloys with good corrosion resistance and good thermal insulation properties may be preferred. Furthermore, in the upper part and / or lower part openings for attaching locks, switches and the like. And / or for the implementation of cables and cables may be formed. The attachment of locks, switches and the like. And / or implementation of cables and cables is also possible in the space formed between the upper part and lower part.

Upper part and lower part are connected to each other by webs of metal. The webs may be designed such that a distance from the upper part or lower part is possible at any time.

Preferably, upper part and lower part are equally spaced over the entire length of the profile.

According to the invention, at least one reflector plate is arranged between upper part and lower part.

The at least one reflector plate preferably extends substantially over the entire width of the profile. Preferably, the at least one reflector plate also extends over the entire length of the profile.

Depending on the width of the profile and thickness of the web arrangement, the effect of the reflector plate can already be achieved by the surface of the webs, which are formed parallel to the upper part or lower part. In such a case, the webs preferably additionally comprise sections which run parallel to the upper part and / or lower part and serve as a reflector surface.

The longitudinal axis of the upper or lower part corresponds to a longitudinal direction of the upper or lower part, which is usually also referred to as length and represents the largest dimension of the upper and lower parts. The width of the profile extends according to the invention perpendicular to the length in the plane of the outer wall.

It has been found that for a good thermal insulation, the reflector plate to extend substantially over the entire width of the profile and the connection between the upper part and lower part via webs and not to have a continuous wall. The webs are for weight and Wärmeleitgründen (reduction of the lambda value) to be preferred.

Preferably, the webs, with respect to the longitudinal axis of the upper part and lower part, respectively in a first and second side region of the upper or lower part. In this case, the at least one reflector plate extends from the webs of the first side region to the webs of the second side region. It has been shown that it is not necessary for a good thermal insulation, that the side portions of the profile are completely closed. It is sufficient that the reflector plate extends substantially over the entire width of the profile. Thus, only webs can be arranged in the side regions, which for weight and Wärmeleitgründen to prefer are. The reflector plate also stiffens the profile, so that the webs can be made correspondingly narrow and lightweight.

By suitable design of the arrangement of upper part, lower part and reflector plate (s), in particular the thickness of the reflector plate (s) and their distance, a bullet-resistant effect can also be achieved. To achieve a higher shot-stop class, additional materials may be used. For example, additional armor made of a metal and / or synthetic fibers (e.g., aramid) may be placed in the top and / or bottom and / or in the space formed between top and bottom. Upper part and / or lower part can also or alternatively be manufactured as a solid profile.

The webs of the respective side region are preferably strung together, so that in each case in the first and second side region, the webs are arranged in alignment in the longitudinal direction.

Alternatively, the profile may have juxtaposed webs which connect the upper part and lower part with each other. In this case, only a single row of webs is present, which is preferably arranged centrally of the upper part and / or lower part. Such a design is particularly advantageous for very narrow in width profiles formed.

The at least one reflector plate preferably has one or two substantially flat reflector surfaces.

A substantially flat reflector surface is simple in production and also best suited for the reflective properties of the reflector surface.

Preferably, the profile comprises a plurality of reflector plates with reflector surfaces arranged parallel to one another.

The multiple arrangement of reflector plates, the insulating properties and fire resistance can be improved.

At least one reflector surface is preferably provided with an infrared-radiation-reflective coating. Particularly preferably, the inner surfaces of the upper part and / or lower part facing the reflector surface (s) are also provided with such a coating.

Thus, the return properties of the reflector plate are further improved.

The at least one reflector surface is arranged in particular parallel to the outer wall of the upper part and lower part. More preferably, both upper part and lower part are formed such that one of the reflector plate facing inner wall is also arranged parallel to the reflector surface.

As a result, the insulating properties are further improved.

The reflector plate is preferably made of metal.

In particular, if the reflector plate is not provided with an infrared radiation-reflective coating, reflector plates with a polished surface are particularly preferred because they positively affect the return properties of the reflector plate.

Preferably, the webs are arranged obliquely to form a truss arrangement.

In the context of the invention obliquely means an angle of 1 ° to 89 ° to the longitudinal axis, or 91 ° to 179 °.

A framework arrangement is particularly preferred for the shear strength of the profile. In addition, the webs can be cut or punched from a single metal sheet to form a zigzag profile.

However, the webs can also be arranged perpendicular to the outer wall of the upper part and / or lower part.

Preferably, the at least one reflector plate openings, in which the webs are inserted.

This embodiment provides a simple way of attaching the reflector plate. The reflector plate can be easily attached to the webs.

Additionally or alternatively, the reflector plate may be provided with further means, which serve for attachment to the webs. It is conceivable a connector with locking elements on the web or on the reflector plate, which engage in corresponding openings of the reflector plate or the web. A clamping connection by folding is also conceivable as a screw or rivet connection, a welded connection and / or an adhesive bond.

Another embodiment of the invention provides that the webs are formed of at least two segments and at least a reflector plate is formed as a connecting piece for the two segments.

Preferably, the webs are provided in an end region with fastening means for attachment to the upper part or lower part.

The fastening means may be formed as a latching element, which are inserted into corresponding openings or grooves of the upper or lower part. Conversely, the webs can be provided with openings which cooperate with the insertion into the upper or lower part of me locking means. Alternatively, the connection can be made by clamping, folding or rolling sections of the web with the upper or lower part. Further possibilities are a screw and / or rivet connection and / or a welded connection and / or an adhesive connection.

Preferably, the at least one reflector plate is integrally formed with the webs and / or web segments.

Such a configuration allows easy production of the webs and the reflector plate. Preferably, the webs and / or web segments and the at least one reflector plate are punched or cut out of a single sheet metal part and are then folded to form the three-dimensional structure.

To increase the fire protection properties, the profile may further comprise an intumescent material and / or a water-releasing material (eg, water glass) and / or a heat-insulating material disposed between the top and the bottom and / or only in the top or bottom is. The intumescent material and / or the fire-releasing material (eg water glass) and / or the heat-insulating Material may for example be arranged only between the upper part and the reflector plate or only between two reflector plates.

Preferably, the at least one reflector plate is provided with means for fixing a cover.

The means for fixing a cover are preferably formed as a latching element. Other options such as clamping, screw, rivet and adhesive joints are also conceivable.

The profile and in particular the reflector plates and / or the webs preferably have means for attachment, for example on a wall or for the attachment of locks and the like., On. These means are preferably designed as an opening for a screw or bolt / pin. An advantage of an arrangement of the means for attachment to the webs is that thermal bridges are largely avoided.

The Indian FIG. 1 shown section of a profile consists of an upper part 1 and a lower part 2, which are formed as a hollow profile made of metal. Each of the other part facing away from surface 3 and 4 is referred to as the outer wall. A longitudinal axis L is indicated by the dashed-dotted line.

The upper part 1 and the lower part 1 are connected by obliquely and truss-like webs 5 made of metal. Between upper part 1 and lower part 2, parallel to the outer walls 3 and 4 reflector plates 8 and 8 'are arranged of a metal, which extend over the entire length and width of the profile. Each of the adjacent upper part 1 and lower part 2 facing surface is referred to as a reflector surface 9 or 9 'and is flat and polished. The remaining, the other reflector plate facing surface is referred to as a reflector surface 99 and 99 'and is also flat and polished.

Like from the FIG. 1 it can be seen that the webs 5 are each arranged in a side region 6 and 7 of the upper part 1 and lower part 2.

The reflector plate 8 or 8 'has curved side parts 11, which serve as fastening means for a side cover, not shown here.

The FIGS. 2a and 2b show possible variants of a shell 1 on. The in the FIGS. 2a and 2b Variants shown are also applicable to the lower part 2 accordingly.

The upper part 1 of FIG. 2a is designed as a hollow profile. On the wall facing away from the outer wall openings 12 are provided for fixing the webs 5.

The upper part 1 of FIG. 2b is formed as a composite profile and consists of a sub-profile 13 of metal and a slip-14. The attachment profile 14 may be made of an example optically appealing material such as stone, plastic or wood. The sub-profile 13 also has locking lugs 15, which serve for fastening of the attachment profile 14. In Aufsteckprofil 14 recesses 16 are also provided, which coincide with plug-on profile 14 with the openings 12 of the sub-profile 13 and serve to fasten the webs 5.

The attachment of the webs 5 is in the FIG. 3 shown.

According to FIG. 3a For example, an end region 53 of a web 5 can be provided with a latching nose 55, which engages behind it after being inserted into the opening 12 of the upper part 1.

The compound can also according to FIG. 3b take place by folding or curling an end portion 53 of the web 5 with a correspondingly formed receiving portion of the upper part 1.

Also possible is a connection by means of a screw or a pin / bolt (shown schematically by the line 55), as in the Figure 3c shown.

According to 3d figure an end portion 53 of the web 5 is welded to the upper part 1.

From the FIG. 3e It can be seen that the end portion 53 can be bent by 90 ° and glued to the upper part 1.

Accordingly applies to the connection with a lower part 2 in an end region 54 of the web. 5

In the FIGS. 4 to 8 Various possibilities of attachment of the reflector plate 8 with the web 5 are shown.

The in the FIG. 4a shown connector, which in detail in the FIG. 4b is visible, is realized by the fact that the reflector plate 8 has an opening 17. The web 5 has a portion 18 which is bent and arranged parallel to the reflector plate 8. A latching lug 19, which is formed in the section 18, engages in the opening 17 and thus connects the reflector plate 8 with the web 5 in a form-fitting manner.

In the FIGS. 5 to 8 are alternatives to the plug connection of FIG. 4 shown.

In the FIGS. 5a and 5b is visible that an end portion 53 'of the web 5 is folded with an edge portion 20 of the reflector plate 8 to produce a clamping connection.

In the Figures 6a and 6b a screw connection is shown. The reflector plate 8 is by means of a screw 21 with a bent portion 18 (analogous to FIG. 4 ) of the web 5 connected. Instead of the screw 21 can also find a rivet application.

Another alternative is in the FIGS. 7a shown to us 7b. There, an edge of the reflector plate 8 is brought into contact with an edge of the web 5 and welded.

Finally, in the FIGS. 8a and 8b an adhesive bond shown. Analogous to FIG. 4 a portion 18 of the web 5 is bent, so that the portion 18 extends parallel to the reflector plate 8. Between section 18 and reflector plate 8, an adhesive layer 22 is then attached.

In the FIGS. 9a to 9d For example, different cross sections of the webs 5 are shown. In addition to the rectangular cross section shown in the other figures FIG. 9a can the webs 5, depending on the static requirements, also a curved section ( FIG. 9b ), a round cross-section (Figure 9c), which may also be formed of a solid metal rod, or an L-shaped cross section ( FIG. 9d ) respectively.

In the FIG. 10 is shown a possible wall mounting. In the region of the curved side parts 11, projections 23 are formed with an opening 24, which are used for fastening the profile.

In the FIG. 11 an alternative is shown, which additionally allows the attachment of locking mechanisms. The openings 24 are formed in connecting portions 25 which connect the reflector plate 8 and the reflector plate 8 '. The connecting sections 25 can be formed integrally with the reflector plates 8 and 8 'or as a separate component, which is subsequently connected to the reflector plates 8 and 8'.

In the FIG. 12a a possibility of forming a reflector plate 8 with webs 5 is shown. Like from the FIG. 12b can be seen, the reflector plate 8 and the webs 5 are cut out of a layer of metal and then folded. To form the side parts 11, the side parts 11 are bent along the folding line 26 with respect to the sheet plane up or down by 90 °. The webs 5 are also bent either along the fold line 27 up or the fold line 28 down. The end portions 53 and 54 of the webs 5 are in the FIG. 12 shown purely schematically, but include mounting options for the upper and lower part, preferably in the FIG. 3 shown mounting options.

In the FIG. 13a a construction with two reflector plates 8 and 8 'is shown, which is formed from a single folded sheet metal part. The cutout pattern is in the FIG. 13b visible.

It should be noted that the end portions 53 and 54 with a detent 55 and 56, as in the FIG. 3a shown are equipped.

Furthermore, the sections 18 are visible, which are provided with an opening 21 '. When folding the construction, the openings 21 'come into conformity with the openings 21 "of the reflector plate 8, so that a corresponding screw connection, as in FIG. 6 , can come about. Of course, the sections 18 may also be configured differently, so that one of the in the FIGS. 4 to 8 shown mounting options is also conceivable.

In the FIGS. 13c to 13h are the bending steps for producing a reflector assembly according to FIG. 13a shown. In the the FIGS. 13c to 13h However, the order of steps shown is not binding.

First, according to FIG. 13c the end portions 53 and 54 bent by 90 ° with respect to the sheet plane.

After that, as in the FIG. 13d shown, the cover fasteners 11 are also bent by 90 ° on the same side of the sheet plane as the end portions 53 and 54.

According to FIG. 13e Then, the plane of the reflector plate 8 is bent by 90 ° with respect to the plane of the reflector plate 8 '.

In the following step the FIG. 13f the reflector plate 8 'is also bent by 90 °, so that the reflector plate 8 and 8' are now parallel to each other and the end portions 53 and 54 are arranged facing away from each other.

The section 18 is then folded by 90 °, as in the Figure 13g shown.

Subsequently, according to FIG. 13h the reflector assembly closed by the webs 5 are bent with the portion 18 by 90 ° until the portion 18 abuts against the reflector plate 8.

In the FIG. 14 an exploded view of another embodiment of the inventive profile is shown. Upper part 1 and lower part 2 have openings 12, which are formed for insertion of the webs 5. The webs 5 are formed as a stamped part and have sections 51, which are provided with openings 52. The sections 51 extend parallel to the upper part 1 or lower part 2. The reflector plates 8 and 8 'have at the side edges projections 81, which in terms of dimensions and spacing are matched to the openings 52 so that the projections 81 are inserted into the openings 52 for positioning and fixing the reflector plates 8 and 8 '. An attachment of the projections 81 is also conceivable. The end portions 53 and 54 of the webs 5 are preferably according to FIG. 3 connected to the upper part 1 and lower part 2.

In the FIG. 15 a further embodiment of the inventive profile is shown. The upper part 1 and the lower part 2 are also provided with openings 12 which serve for fastening the webs 5. Like from the FIG. 15 As can be seen, the profile is formed from a sandwich arrangement. The reflector plate 8 or 8 'is formed by joining both plates 82 and 83 or 84 and 85. The plates 82 and 83 or 84 and 85 are preferably glued or welded. The end portions 53 and 54 of the webs 5 are preferably according to FIG. 3 connected to the upper part 1 and lower part 2.

In the FIG. 16 a further variant of the inventive profile is shown. The upper part 1 and the lower part 2 are also provided with openings 12 which serve for fastening the webs 5. The reflector plates 8 and 8 'have openings 10, which are formed for the passage of the webs 5. The webs 5 are cut / punched out of a single sheet metal part and run with a zigzag pattern. On the webs 5 holding areas 57 for the reflector plates 8 and 8 'are formed. After insertion of the webs 5 in the openings 10 of the reflector plates 8 and 8 'engage the holding areas 57 and fix the reflector plates 8 and 8'. The attachment of the webs 5 with the upper part 1 and the lower part 2 takes place as above with respect to the FIG. 3 mentioned. In this case, the attachment takes place by means of locking lugs 55 and 56th

The inventive profile may also include a single row of webs 5, as in the FIGS. 17 and 18 shown. These embodiments are particularly preferred when the profile must be made very narrow. Depending on the embodiment, a width of 6 mm is possible, which allows a very filigree design of components.

Like in the Figure 17a Visible is the profile shown there formed in several parts. Upper part 1 and lower part 2 are connected by webs 5, which are formed like a truss. Upper part 1 and lower part 2 are preferably welded to the central part, which has the webs 5. The reflector plates 8, 8 'and 8 "are integrally formed with the webs 5 and extend parallel to the upper part 1 and the lower part 2. As shown in FIG. 17b Visible protrude the reflector plates 8, 8 'and 8 "side of the webs 5 out.

In the FIG. 18 is also a profile according to the invention shown with a single row of webs, which, however, is formed from a single sheet metal part. Like in the FIG. 18b visible upper part 1 and lower part 2 are formed from a folded sheet metal. The webs 5 are formed by cutting / punching. In this case, the reflector surfaces 8 and 8 'are formed by the portions 51, which extend parallel to the upper part 1 and lower part 2 and the webs 5 intersect.
