Description

The invention relates to a frame composed of frame profiles for a window or a door with a facing shell made of facing profiles, the facing profiles consisting in particular of aluminum.

Technical field

Plastic has established itself as a material for frame profiles for the production of windows and doors in many markets due to the rational processing and durability of the products. The vast majority of these plastic profiles are extruded from PVC-U, whereby the seals made of PVC-P or TPE are either co-extruded if possible or - even more frequently - extruded in the so-called post-coextrusion process (PCE process). Both co-extruded and post-co-extruded seals can usually be welded with plastic profiles in the miter area, which is of great importance for efficient further processing.

The use of facing panels made of aluminum profiles is generally known for both wooden and plastic windows. Plastic profiles are clad with aluminum shells primarily for aesthetic reasons, whereby the aluminum shells can be anodized, painted or coated in different colors. The systems are usually designed in such a way that the same main profiles can be used both with and without facing shells.

State of the art

From the EP 0 517 057 A2 is a profile system with frame profiles made of plastic and attachment profiles made of aluminum, in which the frame and the sash after welding First of all, provide button-shaped holders on the outer visible surface, onto which the aluminum cladding is then clipped. A disadvantage of this profile system is that the structural depth of the frames inevitably increases considerably due to the facing shells and thus the freedom of design is restricted.

The one from the EP 1 022 423 A2 Known profile system, a special plastic frame profile and an aluminum facing profile are used, each of which has a groove-shaped undercut, which together form a receiving groove for a special glazing seal. However, such profile systems have the disadvantage that special casement profiles have to be used, the manufacture of which requires very high investments. In addition, post-coextruded seals (PCE seals) are not possible with this design.

From the DE 10 2005 036 240 A1 a generic profile system or a generic frame with a rounded visible surface area of the frame profile is known, in which the facing shell profiles for the casement either have a separate seal or are clamped behind a special seal at the end of the upper rounded region of the rollover of the frame profile. This construction also requires special seals that cannot be manufactured using the PCE process.

From the DE 74 07 107 U1 ( Fig. 1 ) and the EP 2 360 342 B1 ( Fig. 5 ) Sash frames made of plastic profiles are known, in which very simply designed facing shell profiles are used, which, viewed in cross-section, have chamfers or nose-like or hook-shaped projections at their ends, which grip around the outside profile wall of the frame profile in the lower area, on the other side ( above) hook behind the top edge of the outer frame rollover while doing so reach behind the glazing or outer stop seal of the frame profile. These generic constructions are very simple in design and enable the construction of very flat facing shells. However, they have the disadvantage of being able to accommodate only small tolerances in the plastic and facing shell profiles, since with larger deviations in the dimensions the clipping on of the facing shells is either too difficult or the facing shells are too loose. These constructions also have the disadvantage of requiring a special glazing or outer stop seal, since with standard PCE seals it is not readily possible to hook the facing shell on the upper edge of the outer rollover.

task

It is therefore an object of the present invention to provide a profile system or a composite frame with a facing that avoids these disadvantages.

Presentation of the invention

The invention solves this problem by a frame composed of frame profiles according to claim 1 or a system according to claim 13, preferably in conjunction with one or more of the features of subclaims 2 to 12.

The frame profiles are preferably made of plastic, in particular hard PVC, so that they can be welded together in the miter area. Accordingly, the frames used according to the invention are preferably composed of frame profiles made of hard PVC (PVC-U) welded together in the miter area. Conventional frame profiles are preferably used, which can be processed both with and without the facing shell used according to the invention into plastic casement frames or plastic frame frames.

The frame profiles used according to the invention have an outer visible surface, a fold area and an outer flap which delimits the fold area. A frame made from it thus corresponds to the usual state of the art and can be glazed conventionally.

According to a particularly preferred embodiment of the invention, the frame profiles used have a seal co-extruded during the extrusion of the frame profile or post-co-extruded in the PCE process. As far as the frame is glazed, this seal represents the outer glazing seal. The PCE process for the production of seals for plastic profiles for windows and doors is from, for example EP 0 290 536 B1 known and has generally established itself in the market for plastic profiles for windows and doors.

In principle, however, the seal used can also be subsequently rolled or drawn into a seal receiving groove in the rollover of the frame profile. However, the advantages of the present invention are best used if the seal according to the invention is coextruded or post-coextruded in the rollover of the frame profiles with the frame profiles.

The frame profiles used according to the invention - as is customary in the prior art - have a rollover on the outside, which - viewed in cross section - is inclined in the upper visible area to the glazing plane A, that is, for example, runs horizontally, but in particular obliquely at an angle α of, for example, 95 to 175 °, such as from the EP 1 923 532 A2 is known, runs, or has a correspondingly stepped or rounded upper visible surface area, such as that from the DE 10 2005 036 240 A1 is known.

The attachment profiles used according to the invention, preferably made of aluminum or other metallic materials, have according to the invention an undercut in its overlap area. In this application, viewed in cross section, the area of overlap of the facing profiles is the area of the facing facing the glazing that completely covers the upper visible area of the overlap of the frame profiles inclined to the glazing plane. According to a preferred embodiment of the invention, this overlap area of the facing profiles projects over the overlap of the frame profiles in the direction of the glazing plane by a few tenths to a few millimeters and presses on the upper area of the seal of the overlap, so that there is any gap between the facing shell and the frame on it Body is reliably sealed.

The core of the present invention is the use of elastic, in particular resiliently deformable, fastening means which, when viewed in cross section, are fastened to the upper visible surface areas of the rollovers of the frame profiles inclined to the glazing plane, spring back behind the undercuts of the facing profiles during assembly of the facing profiles and thus one enable positive attachment of the attachment profiles on the frame profiles.

Preferably, the area of overlap of the facing profiles on their inner side, which is normally not visible in the assembled state, extends at the end facing the glazing plane at an angle β <90 degrees to the glazing plane. It is hereby achieved that the attachment shell forms an inclined plane when applied to the frame profile, which compress the particularly resiliently deformable fastening means until the latter can spring back behind the undercut.

In a first embodiment of the invention, round sleeves, for example made of metal, are preferably used as the elastically deformable fastening means, into which a spiral spring and a short pen are inserted. At the upper end of the sleeve, this preferably has a projecting area, so that the sleeve is prevented from being pressed too deeply into the bore. When unloaded, the pin protrudes a few millimeters from the sleeve, but can be easily inserted into the sleeve by overcoming the spring force.

According to an alternative embodiment of the invention, a correspondingly shaped plug made of rubber-elastic material, produced for example by injection molding from TPE, is used as the elastically deformable fastening means. This stopper preferably has a cylindrical area at one end, with which the stopper is inserted into an especially drilled hole in the area of the rollover of the frame profiles. At the upper end of the plug, this preferably has a projecting area, so that the plug is prevented from being pressed too deep into the bore.

If, according to a preferred embodiment of the invention, the projecting area of the stopper has an inclined area directed towards the outside, the facing shell can be easily pushed over the stopper with appropriate compression of the rubber-elastic material, the appropriately compressed stopper being placed behind the undercut after the facing profile has been completely slipped on springs back of the facing profile and accordingly results in a form-fitting anchoring of the facing shell on the frame profile.

According to a third alternative embodiment of the invention, stamped parts are used as elastically deformable fastening means made of metal and / or plastic, particularly preferably made of thin spring steel or the like, which have, for example, a sleeve-shaped fastening region and a leaf-shaped spring region connected to it. Such parts stamped from metal or molded from plastic are pronounced inexpensive to manufacture and - as long as the fastening area is sleeve-shaped - can be easily inserted into a corresponding hole in the overlap of the frame profiles. At the upper end of the fastening area, this preferably has a projecting area, so that the fastening area is prevented from being pressed too deeply into the bore. As far as the leaf-shaped spring area protrudes from the fastening area at an oblique angle according to a preferred embodiment of the invention, it is in turn ensured that, on the one hand, the attachment of the attachment profiles is carried out by simply sliding onto the overlap of the frame profile with simultaneous elastic deformation of the leaf-shaped spring area when the end position of the Attachment profile the leaf-shaped spring area springs back behind the undercut of the attachment profiles and thus brings about a form-fitting attachment of the attachment profiles to the frame profiles.

As already explained above, the upper visible surface areas of the frame profiles, which are inclined to the glazing plane, in particular inclined or stepped or rounded, preferably have bores or openings in which the particularly resiliently deformable fastening means used according to the invention can be inserted. It has proven to be expedient if these bores or perforations - viewed in the direction of the longitudinal extent of the profiles - are arranged at a distance of 50 to 500 mm. If in doubt, the desired distance can be determined by simple tests.

The cross section of the end of the facing profiles opposite the overlap region preferably has a bevel or a hook-shaped projection or the like. with which the front profile in the assembled state in the lower area, for example, positively engages around the outside profile wall of the frame profile. To assemble the facing profiles on the frame already welded in the miter area, they are first attached to the lower edge of the profile wall of the respective frame profile with their end opposite the overlap area in such a way that it is encompassed in a form-fitting manner. The attachment profile is then placed on the frame profile with a rotating or swiveling movement, the upper edge and / or the inside of the overlap area of the attachment profile elastically deforming the elastically deformable fastening means until the fastening means behind the undercut of the attachment profiles has been reached when the end position of the attachment profile has been reached springs back and thus brings about a form-fitting attachment of the facing profiles to the frame profiles.

The frames according to the invention composed of frame profiles for a window or a door can be designed as sash and / or as a frame and can also be combined with commercially available facing shells. They enable a free, in particular a slim design of the attachment profiles, can compensate for considerable tolerances and enable very simple and efficient assembly. Above all, however, the frame profiles can be equipped with standard PCE seals without having to adapt the seals when using the facing shells. Of course, according to the present invention, the frames composed of frame profiles for a window or a door can also include post and cuff profiles which are provided with facing shells by means of the fastening means used according to the invention.

Ways of Carrying Out the Invention

In Fig. 1 a first embodiment of the invention is shown in cross section. The window 4 shown has a window frame and a frame 2 according to the invention designed as a casement. The casement is made of commercially available plastic profiles, which are extruded from hard PVC (PVC-U), cut to length at 45 degrees in the miter area and welded together. The in Fig. 1 The frame shown has commercially available facing shells, but it would also be possible to design the facing shells of the frame according to the invention.

The standard sash used in Fig. 1 has on its outside a rollover 9 which, as is customary in the prior art, delimits the fold area 8 as a hollow chamber towards the outside and supports the glazing 10 from the outside via the post-coextruded seal 12. From the inside, the glazing 10 is held by an appropriate glazing bead, as is customary in the prior art.

In Fig. 1 the glazing level is marked with "A". In the exemplary embodiment shown, the rollover 9 runs in the upper visible surface area 11 at an angle α of 105 ° to the glazing plane A, that is to say it slopes outwards at an angle of 15 ° with respect to the horizontal. Alternatively, this can upper visible surface area 11 of the outer visible surface 7 of the frame profile may also be stepped or rounded, such as corresponding to FIG DE 10 2005 036 240 A1 ,

The visible surface area 11 has - as in FIGS 1 to 4 to recognize holes, which in the illustrated embodiment have a distance of 100 mm in the longitudinal extension of the frame profile 1. The diameter of these bores is 5 mm in the exemplary embodiments shown and is adapted to the outer diameter of the fastening regions 21 of the fastening means 17, 17 ', 17 ".

The attachment profiles 6 form the attachment shell 5 and have a bend in their lower area, the dimensions of which are adapted to a lower projecting edge of the outer wall of the frame profile 1, so that in the assembled state the bend of the attachment shell 5 encompasses this projecting area of the outer wall of the frame profile 1 , At the opposite end - viewed in cross section - the facing shell 5 has an overlap area 15, which in the example shown is almost horizontal and faces the glazing 10, and which completely covers the upper visible area 11 of the frame profile 1. On the inside 14 of the facing shell 5, which is not visible in the assembled state, the facing shell 5 has an undercut 16 ( 2 and 3 ), behind which the fastening means 17, 17 ', 17 "can reach behind during the assembly of the facing shell profiles 6.

As especially in the 2 to 4 can be seen, in the examples shown the overlap area 15 of the facing profiles 6 projects beyond the overlap 9 of the frame profiles 1 in the direction of the glazing 10 by approximately 1 mm. He presses with a certain preload on the, in the Fig. 1-4 area of the PCE seal 12 at the top 1 to 4 can be seen that the PCE seal 12 the rollover 9 in the upper area by a few millimeters. During glazing, this area is pressed outwards in the direction of the flap 9 and the tip of the overlap area 15 of the facing shell 5, so that a reliable sealing of the facing shell 5 is achieved.

With the in Fig. 2 as a cut-out rollover 9 of the frame profile 1, a first embodiment of the invention is shown enlarged. A device consisting essentially of the sleeve-shaped holder 18, a helical spring 19 inserted therein and a cylindrical pin projecting above the sleeve is used as the spring-elastic deformable fastening means 17. Similar to the mechanism of a ballpoint pen, when the attachment profiles 6 are put on, this pin is pressed into the holder 18 with elastic deformation of the helical spring 19. After the attachment profile 6 has been completely seated, the pin can spring back accordingly and reach behind the undercut 16 of the attachment profile 6.

At the in Fig. 3 Alternative embodiment shown is used as an elastically deformable fastening means 17 ', a rubber-elastic material which has an approximately cylindrical mounting area in the lower region, which is inserted into the corresponding bore 22 of the rollover 9 of the frame profile 1. In the area of the upper, obliquely running visible surface area 11 of the flap 9, this molded part projects over the fastening area with a surface that slopes away towards the outside. Together with the inside 14 of the facing profile 6, which extends at an angle β = 75 ° with respect to the glazing plane A, the facing profiles 6 can thus be easily pushed over the fastening means 17 'until the correspondingly compressed overhanging area of the fastening means 17' springs back behind the undercut 16.

In 4 and 5 Another embodiment of the present invention is shown. In this exemplary embodiment, a fastening part made of thin spring steel, consisting essentially of a sleeve-shaped fastening region 21 and a leaf-shaped spring region 20 projecting obliquely therefrom, is used as fastening means 17 ″. This is pushed into the bore 22 in a clamping manner, so that the leaf-shaped spring region 20 is inclined Protrudes at an angle to the glazing 10 over the upper oblique visible surface area 11 of the flap 9. The attachment of the facing profiles 6 is carried out analogously to that in FIGS 2 and 3 illustrated examples, in that the attachment profiles 6 initially in the lower region around the protruding edge of the outer visible surface of the frame profile 1 ( Fig. 1 ) are pushed and then put over the fastening means 17 ″ with a rotary movement with the overlap region 15 until the leaf-shaped spring region 20 springs back behind the undercut 16 of the attachment profile 6 in the end position.
