Abstract

The window or door profile (1) has a profile body (2), which is formed as hollow chamber profile. Multiple hollow chambers (6,8) are arranged in the profile body, which are bounded from outer walls (4) or inner webs (5,7). One of the interior webs thick-walled with a wall thickness of 70 percent of the wall thickness forms one of the external walls such that the wall thickness of the interior web limits to 1.5 millimeter. The window or door profile is made of plastic.

Description

The invention relates to a window or door profile made of plastic with a profile body which is designed as a hollow chamber profile, wherein in the profile body a plurality of hollow chambers are arranged, which are bounded by outer walls and / or inner webs, as well as provided with a window or door.

Plastic profiles for window and door elements are usually hollow chamber profiles, which are produced by extrusion, said hollow chamber profiles have several Hohkammern, on the one hand to obtain a certain stiffening of the plastic profile over the webs, and on the other hand to improve the thermal insulation. For stiffening metal profiles are usually introduced in these hollow sections. However, there are already efforts to replace these metal profiles. So is, for example, from the DE 198 43 742 A1 a plastic profile for windows and doors known, which is constructed in three parts, with a profile core and an outer shell and an inner shell. The profile core serves to stiffen the profile and may consist of a glass fiber reinforced plastic, wherein preferably this profile core has a honeycomb-shaped cross-sectional structure.

Object of the present invention is to develop a window or door profile such that this offers a higher functionality.

This object of the invention is achieved in that at least one of the inner webs of the profile body is thick-walled, with a wall thickness of at least 70% of the wall thickness of at least one of the outer walls, with the proviso that the wall thickness of the Innensfeges is at least 1.5 mm, and by a door or a window which is equipped with the hollow chamber profile according to the invention. It is thus possible to form windows or doors - apart from metallic fittings - metal-free, so without the usual and previously necessary metallic reinforcement, so that the production of the hollow chamber profile is simplified in that the subsequent introduction of such metallic stiffeners is not always required. For very heavy or large windows, metal stiffening, as is customary in the prior art, can be provided. Compared to the prior art, however, results in this case, a better load transfer. Namely, metal profiles are usually used, which is a relative have great game to the walls of the hollow chambers, in addition to production due to the certain delays in the hollow chamber profile are present, so that buckling of the metal profiles can not be or only partially prevented. By the inner webs according to the invention an improvement can be achieved here. In addition, it is within the scope of the invention, the possibility to arrange so-called. Pilots for load transfer within the hollow chamber profile in order to achieve a direct load dissipation in the surrounding masonry on the profile. These pilots can be approximately punktformig, eg with a diameter of 0.15 mm, be, in which case mushroom-shaped diameter extensions to increase the footprint for a glass element are possible, or linear, for example, with a footprint for a glass element of 4 x 8 cm. These pilots can be provided between the thick-walled inner web, or optionally the Metallversteigung, and the glass element, in particular two pilots per glass element. The pilots may for example consist of plastic, in particular be connected to the hollow chamber profile, for example, be made in one piece with this, or made of wood. It is also possible that the pilots are made with an over-height to allow on-site adaptation, eg by milling. Of course, this adaptation is also possible if pilots are used without over-height. It is thus also the thermal insulation value of the hollow chamber profile per se, and improved as a result, the thermal insulation of the entire window or the entire door in which it is namely possible to reduce the face width of the hollow chamber profile - compared to hollow chamber profiles from the prior art - whereby the glass content of a window of a certain size can be made higher compared to a window of the prior art. Since the weak point in the thermal insulation is known to be in the frame itself - two or three panes of insulating glass windows are known to have a thermal insulation value better than that of the frame - thus reducing the proportion of the frame on the window itself improves thermal insulation become. In addition, the advantage is achieved that the light and energy transmission can be improved by the higher glass content. As an additional effect, a better appearance of the window is thus achieved, which is particularly advantageous in view of the current trend towards large-area glass fronts. In addition, the attachment of fitting parts to such windows is simpler and these hollow chamber profiles according to the invention also have better pull-out values for screws. Due to the higher wall thickness of at least one of the inner webs of the hollow chamber profile on the one hand, a higher mechanical strength of the profile itself achieved, so that therefore larger and heavier glass elements such as soundproof windows, security windows, triple glazing eg for glass facades are possible, beyond that also increases the flexibility of the profiles, as well as milled profiles are possible, for example, to geometric adjustments Place or generally to adapt the optics on-site without losing the stability of the hollow section profile. The milling operations can also be carried out, for example, such that a hollow chamber is partially opened for receiving a fitting part, or that the stop region of a window is increased by a further folding step, by at least partially removing a corner of the profile. As a result of this greater flexibility and functionality of the profiles, it is thus possible to provide a profile for a plurality of applications or configurations of windows or doors, so that only an extrusion tool or tool for producing such hollow chamber profiles is required for a wide variety of window types and sizes, and thus also investment costs can be saved. With the invention, the buckling of the profiles in the Profilendbereichen be avoided, as may occur in the prior art window, since the metal stiffening can not extend to the ends due to the welding of the profiles. With the hollow chamber profile according to the invention also a reduction in raw material and thus a cost savings can be achieved.

It has proven to be particularly advantageous if the wall thickness of the thick-walled inner web is selected from an area with a lower limit of 80% and an upper limit of 130% of the wall thickness of at least one of the outer walls. On the one hand, the profile is given a higher strength by increasing the wall thickness to at least 80% of the wall thickness of an outer wall, so that these profiles also have corresponding emergency reserves with respect to load capacity for higher loads. With regard to the upper limit of 130%, it was possible to observe an optimum relationship between mechanical load capacity and material cost or weight of the frame profile, whereby it should be noted that a further increase in wall thickness to more than 130% is of course possible and provides a higher mechanical stability , but not to the extent that it also increases the weight of the hollow chamber profile. In addition, with higher wall thicknesses, a reduction of the extrusion speed may be required, which would increase the production costs. Also, the dimensional tolerances up to this limit are better than above.

The at least one thick-walled inner web can extend from a first outer wall to a second outer wall, that is to say run through the entire hollow-chamber profile, for example, extending vertically or horizontally. It can thus the hollow chamber profile, d. H. the window or door profile, depending on requirements, a higher transverse stiffness or stiffening are given in the direction of gravity, making it possible, the other inner webs are usually made thin-walled, this wall thickness is usually about 0 in conventional, known from the prior art hollow chamber profiles , 6 mm to 1.2 mm, can be reduced without sacrificing the mechanical stability of the window or door profile.

It is also possible that a plurality of thick-walled inner webs, possibly with at least one of the outer walls, a - viewed in cross-section - closed chamber form. With this embodiment of the invention, it is possible to provide this chamber for receiving fitting parts, so that these fitting parts are thus at least partially concealed lying in the window or door profile, for example. Corner. By this integration of fitting parts in the window or door profile itself a reduction of the seaming air is possible, as well as a further reduction of the view width of such hollow chamber profiles, thus further increasing the thermal insulation can be achieved, and beyond the appearance of such windows or doors can be improved because the proportion of visible metallic fittings is reduced.

The at least one thick-walled inner web can be arranged between thin-walled inner webs, which have a wall thickness of less than 70% of the wall thickness at least one of the outer walls, and in particular be connected to these, so that a stiffening of the door or window profile is achieved even if this thick-walled inner web is not connected to the outer walls, but is connected only via the thin-walled inner webs in the window or door profile.

To further increase the mechanical strength of a window or door, which is equipped with the window or door profile according to the invention, it is possible that at least one surface of the or the thick-walled inner webs (s) at least one extending in the longitudinal extent of the profile body web is arranged, so substantially a thickening of material is formed.

The formation of a connecting element on at least one surface of the thick-walled inner web for a fitting element of a window or a door, for example. In the form of a clip connection or a clip element, in particular with hook-shaped end extensions, these connecting elements preferably already during production in the hollow chamber profile ie in the window or door profile, are formed from the material of the profile, the mounting of such hardware elements in the window or door profile and its support is simplified, whereby the assembly cost can be reduced in itself.

A further increase in the stiffening or the functionality of the window or door profiles can be achieved if the at least one thick-walled inner web is formed from a particle-reinforced or fiber-reinforced plastic.

With the exception of the fitting elements metal-free design of a window or a door with the window or door profiles according to the invention, it is possible to increase the thermal insulation value of such a window or door, in which the disadvantage of high thermal conductivity of metal parts is avoided or reduced.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, identical parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be applied mutatis mutandis to the same parts with the same reference numerals or identical component names. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these are mutatis mutandis to transfer to a new position to the new situation. Furthermore, individual features or combinations of features from the illustrated and described, different embodiments may represent for themselves, inventive or inventive solutions.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7 or 3.2 to 8.1 or 5.5 to 10.

Fig. 1 shows the cross section of a first embodiment of a window or door profile according to the invention 1. This window or door profile 1 has a profile body 2, which is formed as a hollow chamber profile 3. For this purpose, on the one hand on the profile body 2 outer walls 4 formed as an outer boundary of the profile and on the other hand inner webs 5. The outer walls 4 form with the inner webs 5 a plurality of hollow chambers. 6

In this embodiment variant of the window or door profile 1, a horizontally arranged inner web 7 is thick-walled, with a wall thickness which corresponds to that wall thickness which the outer walls 4 have. This inner web 7 is not directly connected to the outer walls 4, but integrated via thin-walled inner webs 5 in the profile body 2. It is thus possible to form a relatively centrally arranged in the window or door profile hollow chamber 8 bulky, this hollow chamber 8 is divided by the thick-walled inner web 7 into two partial cavities, whereby the thermal insulation of this window or door profile 1 can be improved as a cold Outside area 9 is separated via the large-volume hollow chamber 8 of a warm inner region 10 of a window or a door. In addition, it is achieved via this thick-walled inner web 7, that a bulge of the thin-walled vertical inner webs 5, which with the thick-walled inner web 7 are connected, at least largely avoided in the direction of the large-volume hollow chamber 8 during the load.

In principle, it is possible in the context of the invention that the thick-walled inner web 7 is formed extending horizontally, vertically or obliquely to the horizontal. Due to the vertical arrangement, better load transfer to the surrounding masonry is achievable, especially for heavy or large windows, so that in most cases additional support such as e.g. Pilots, as will be described in more detail below, can be dispensed with. These vertical webs may extend through the entire hollow chamber profile 1 or up to a horizontal, in particular thick-walled inner web 7, and in particular be arranged directly below the load application point.

The thin-walled inner webs 5 may have, for example, a wall thickness of 0.6 mm to 1.2 mm, the outer walls 4 and the inner web 5, for example, a wall thickness of up to 5 mm. However, these figures are not intended to be limiting and will therefore vary those skilled in the wall thicknesses as needed, and the relative ratio of the wall thickness of the thin-walled inner webs 5 to the thick-walled inner web 7 and the outer walls 4 can be varied. This ratio can be selected from a range with a lower limit of 0.6: 1.5 and an upper limit of 0.6: 6, in particular from a range with a lower limit of 0.6: 1.8 and a upper limit of 0.6: 5.

It is also possible that the window or door profile 1 outer walls 4 having different wall thickness, in which case the thick-walled inner web 7 has a wall thickness of at least 70% of that wall thickness of the outer wall 4 with the thinnest wall thickness of the outer walls 4, but at least of 1.5 mm.

As already mentioned above, the thick-walled inner web 7 preferably has a wall thickness which is selected from an area with a lower limit of 80% and an upper limit of 130% of the wall thickness of at least one of the outer walls 4. In particular, this wall thickness of the inner web 5 be selected from a range with a lower limit of 100% and an upper limit of 120% of the wall thickness of at least one of the outer walls. 4

In the embodiment of the window or door profile 1 to Fig. 2 is formed by two thick-walled inner webs 7 a hollow chamber 11, said hollow chamber 11 is bounded on two sides by the outer walls 4.

It is of course possible that this hollow chamber 11 is adjacent only to one of the side walls 4, or may this hollow chamber 11 also be arranged entirely within the window or door profile 1, without direct contact with one of the outer walls 4 of the profile body. 2

Due to the arrangement of this hollow chamber 11 according to the embodiment according to Fig. 2 In the area of the outer walls 4, it is possible to use this hollow chamber 11 for the arrangement of parts of fitting elements, such as closure elements or corner bearings. For this purpose, this - viewed in cross-section - closed hollow chamber 11, for example. At those locations where fitting parts are to be mounted, be milled or cut, so as to expose the cavity of this hollow chamber 11 and insert the fitting element can. On the other hand, it is possible that after this hollow chamber 11 is formed open in the window or door profile 1 at the end faces - the closure takes place only by welding several window or door profiles 1 to the sash frame or door sash frame - the fitting elements are inserted later, so that only a small portion of this hollow chamber 11 must be opened to allow the intervention of other Beschlagselementteile, such as closing parts.

Although this hollow chamber 11 in Fig. 2 is at least approximately formed with a square cross-section, it is of course possible to give this hollow chamber 11 other cross-sectional shapes, as well as the entire window or door profile. 1

In addition, it should be noted at this point that the window or door profile according to the invention can be used not only as a window sash profile or door sash profile, but, for example, as a frame profile.

Furthermore, it is off Fig. 2 it can be seen that two longitudinal ribs 13 are formed on an inner surface 12 of the thick-walled inner web 7 arranged horizontally in this embodiment variant are. With these longitudinal ribs 13, a further stiffening of this inner web 7 is achieved or is thus a spaced support of fitting elements in the hollow chamber 11 possible. By means of these longitudinal ribs 13 and a level compensation is possible if used in the hollow chamber fitting element by these longitudinal ribs are milled so that a flat "footprint" is formed. It can thus be compensated for smaller manufacturing-related delays.

Of course, it is possible that only one or more than two, e.g. three, longitudinal ribs are arranged.

Instead of or in addition to the longitudinal ribs 13, it is possible in the region of these or in the areas of all those surfaces on which screws could be arranged to arrange so-called screw lugs, in particular on the thick-walled inner web (s) 7, in order to obtain the extraction values for Continue to improve screws. These screw lugs are similar in cross section substantially the longitudinal ribs 13, but the distance between two juxtaposed screw lugs is made smaller, so that these screw lugs are slightly spread when screwing a screw. This screw lugs can be selectively formed and circular or web-shaped, extending over a portion of the longitudinal extent of the profile body 2 extending, with always two screw lugs are arranged side by side.

By further embodiments according to the 3 and 4 of the window or door profile 1 is to be clarified that there are different variations of the arrangement and design of thick-walled inner webs 7 in the profile body 2, so that therefore the illustrated embodiments are not restrictive. So it is, for example, possible to provide below the hollow chamber 11, two thin-walled inner webs 5 as a support for this hollow chamber 8, as in Fig. 3 is shown.

It is also possible, the vertical, thick-walled inner web 7 of the hollow chamber 11 laterally limited to extend such that this thick-walled inner web 7 extends from an outer wall 4 to the outer wall 4 opposite thereto. In addition, as well as in the Fig. 4 is shown, the hollow chamber 11 may still be supported by a thin-walled inner web 5. This thin-walled inner web 5 but can for better load transfer also be thick-walled in the sense of the invention, as in Fig. 4 is shown in dashed lines.

There is also the possibility of only the bottom of the hollow chamber 11 and this vertical web below the bottom (dashed in FIG Fig. 4 ) thick-walled form.

With this possibility of variation within the scope of the invention, it is possible, on the one hand, to vary the mechanical rigidity or, in general, the mechanical properties and mechanical load-bearing capacity of the window or door profile 1. Likewise, the thermal insulation value of this window or door profile 1 can be varied or improved accordingly by the different design of the hollow chambers 6, 8.

The window or door profile 1 is produced according to the prior art via an extrusion process. It is also possible to produce this by injection molding or extrusion.

As a material, a plastic is used, in particular a thermoplastic material such as. PVC, polypropylene. It is also possible to use wood fiber reinforced plastics, so-called WPC (Wood Plastic Composites), e.g. Blends of polypropylene with wood fibers.

In particular, it is advantageous if at least the at least one thick-walled inner web 7 is produced from such a particle-reinforced plastic in order to further increase the mechanical strength.

With the aid of the invention it is possible to provide an area ratio - viewed in cross-section - from plastic to air space or cavity for a window or door profile 1 selected from a range with a lower limit of 1: 0.5 and an upper limit of 1:15, in particular selected from a range with a lower limit of 1: 1 and an upper limit of 1:12, preferably selected from a range with a lower limit of 1: 1.5 and an upper limit of 1: 10, so it is possible to provide a window or door profile 1, which due to the freedom from metal - with the exception of fittings - has a very good thermal insulation. An area ratio of total area inner webs to total area of the cavities - again in cross-section - may be selected from a range with a lower limit of 1: 4 and an upper limit of 1:40, in particular be selected from a range with a lower limit of 1: 5 and an upper limit of 1:35.

With regard to the fitting elements is stated that it is possible even in the profile body 2 itself provide appropriate connection or fastening means, for example. It is possible to extend the longitudinal ribs 13 within the hollow chamber 11 upwards and, for example, the ends with hook-shaped To provide elements so that a fitting element between these extended longitudinal ribs 13 can be clipped.

The design with thick-walled inner webs serves, in particular, to allow the profile to be "selectively" milled only after the extrusion, ie. in the special areas where fitting parts or locking points or parts are mounted. Thus supporting fitting parts or locking points or locking parts can be mounted without loss of strength of the profile or without loss of capacity of the fitting parts or locking points or locking parts. This fitting parts and locking points or locking parts can be mounted concealed, i. lower or at the same height as the non-milled profile section.

It is thus a new assembly of fittings or locking parts without static losses, through the normally very thin inner webs, which are mainly used because of the improved thermal insulation achieved.

Furthermore, this can also be used to an improved, because statically more resilient, glass strip holder.

In addition, it is within the scope of the invention, the possibility to arrange so-called. Pilots for load transfer within the hollow chamber profile in order to achieve a direct load dissipation in the surrounding masonry on the profile. These pilots can be approximately punctiform, for example, with a diameter of 0.15 mm, in which case mushroom-shaped diameter expansions to increase the footprint for a glass element are possible, or linear, for example, with a footprint for a glass element of 4 × 8 cm. These pilots can be provided between the thick-walled inner web, or optionally the metal reinforcement, and the glass element, in particular two pilots per glass element. The pilots may for example consist of plastic, in particular be connected to the hollow chamber profile, for example, be made in one piece with this, or made of wood. It is also possible that the pilots are made with an over-height to allow on-site adaptation, eg by milling. Of course, this adaptation is also possible if pilots are used without over-height.

The embodiments show possible embodiments of the window or door profile 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching technical action by objective invention in the skill of working in this technical field expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

For the sake of order, it should finally be pointed out that in order to better understand the construction of the window or door profile 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.

The problem underlying the independent inventive solutions can be taken from the description.

Above all, the individual in the Fig. 1; 2 ; 3; 4 shown embodiments form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures.
