In 1a is a window element 1 shown. This window element 1 forms a kind of pre-assembled unit and can be integrated as a whole into a wall opening at the installation location. The window element 1 could also be used as a facade element for an element facade or the like.

The window element 1 has a surrounding frame 4th which consists of four frame spars that are aligned at right angles to each other 41 is formed, which are interconnected in the corner areas. In the usual vertical installation position in a wall opening there is therefore a lower, an upper, a right side and a left side frame rail 41a , b , c , d .

The frame 4th also has a frame 4th in two subframes dividing the first inner frame spar 42a on the outer frame 4th in two parts I. , II divided. The inner frame spar 42a extends between two frame bars running parallel to each other 41a , 41b - here as an example between the upper and the lower frame rail 41a , 41b - and abuts them inside, so that between the two ends of the frame spar 42a and the inner edges of the two frame spars 41a, b a T-connection is formed in each case.

One example is purely exemplary II another frame spar 42b at right angles to the first inner frame spar 42a , formed the second part II again into smaller sections IIa , IIb divided. The further frame spar 42b on the one hand bumps against one of the outer frame rails 41 - Here is an example of the right frame spar 41a - On, so that a T-connection is also formed here, and on the other hand at right angles to the first inner frame spar 42a on, so that a T-connection is also formed here. The upper right section IIa is not designed as fixed glazing, but is with an openable and closable movable wing element 3rd Mistake.

The window element 1 can therefore preferably one or more — in this case two — fixed glazing element (s) that cannot be opened 2nd and / or one or more - here one - wing element (s) to be opened 3rd exhibit. The window element 1 has a rectangular basic shape. It is after 1 in a preferred - but not mandatory embodiment, about half of the window element 1 as fixed glazing or fixed element 2a trained, whereas the other half of the window element, for example, both another - smaller - fixed glazing 2 B as well as the wing element 3rd can have.

The respective fixed element 2nd has a circumferential frame area in which a surface element, such as glazing, is inserted. The respective wing element 3rd has a sash that can be opened 5 on the fittings (not shown here) on the frame 4th is struck and can thereby be brought into a tilting position and / or into a rotational position. In the casement 5 a surface element, such as glazing, is preferably used.

The frame bars 41 , 42 are each from a composite profile 400 by cutting the composite profile to length 400 manufactured.

The outer frame bars 41a, b, c, d , which form a rectangular frame, can be connected in each case in corner regions of adjoining bars with corner connectors (not shown) or the like. Such corner connectors, which are inserted, for example, in hollow chambers of the frame spars, are known per se and need not be discussed further here.

Around the window element 1 in this way or in another way, not shown, in fixed glazing elements 2nd and / or wing elements 3rd To be able to subdivide, it is also necessary, among other things, on the frame 4th one or more T-connections between T-shaped butted frame members 41 and 42 or 42 and 42 to train.

A distinction is made between the "outer", continuous frame bars 41 that are part of the rectangular outer frame 4th form the the window element 1 limited to the outside and to the continuous frame bars 41 each adjoining "inner" frame spars 42 , each with a connecting joint in a T version - a T connection - with the respective continuous frame spar 41 are connected. The two inner frame bars 42a , b are also connected to each other with a T-connection.

In the following, a T-connection of a continuous, outer frame spar is used as an example 41 and an abutting inner frame spar 42 described. A connection of two inner frame bars 42a , 42b can be done analogously, then between the continuous frame spar, analogous to the outer frame spar 41 -in the exemplary window element 1 to 1 the frame spar 42a and the adjoining frame spar, analogous to the inner frame spar in the exemplary window element 1 to 1 the frame spar 42b is to be distinguished.

In 2a to 2d are composite profiles 400 shown in different designs. The respective composite profiles 400 common here is their preferred construction from an inner shell 401 , an outer shell 402 as well as two insulating bars 403 , 404 which the inner shell 401 and the outer shell 402 connect with each other. In addition, the composite profiles 400 each (based on an installation situation in a wall) wider on the outside than in the interior area (based on the view of the 2a : here is the main direction of extension of the profiles - i.e. the direction in which the shells are made - perpendicular to the drawing plane and in the direction of the respective glazing or other fixed elements (right, left), the outer shell is wider than the inner shell). This means in short that the outer shells 402 especially the "abutting" profiles are wider than their inner shells 401 .

The inner shell 401 and the outer shell 402 can be made of a metallic material, preferably of a light metal alloy. The insulating bars 403 , 404 are preferably made from a material with good thermal insulation properties, such as a plastic material.

The inner shell 401 and the outer shell 402 each have a hollow chamber 411 , 412 or several hollow chambers 411a , 411b respectively. 412a , 412b on. The insulating bars 403 , 404 and the adjacent metal shells 401 , 402 form together also a hollow chamber 413 from that with one or more insulation strips 405 , 406 can be provided. The hollow chambers 411 , 411a , 411b respectively. 412 , 412a , 412b the inner shell 401 and the outer shell 402 can also each have one or more insulation strips 405 , 406 exhibit.

On the one hand there are hollow chambers 411 , 411a , 411b provided with a rectangular or substantially rectangular cross section and on the other hand hollow chambers 412 , 412a , 412b provided with an L-shaped cross section or substantially L-shaped cross section.

There are also hollow chambers 413 in the manner of a "T-shape" or. "Double L shape".

In the 2a and 2 B and 2d is a composite profile 400 shown as it is preferred for an inner or "abutting" frame spar 42 the T-connection is used. The composite profile 400 is wider towards the outside than inside. This means that the outer shell is wider on two sides (to the right and left as an example in the figures) than the inner shell 401 . Improved burglary protection is to be created here.

The inner shell 401 of the composite profile 400 after the 2a and 2 B has a hollow chamber 411 on. The outer shell 402 of the composite profile 400 to 2a and 2 B has a symmetrical hollow chamber 412 on. This hollow chamber 412 is on average the 2nd perpendicular to their longitudinal extent and to the main longitudinal direction of the profile in the middle lower than to the edges. The corresponding connector is adapted to this geometry.

In 2d a variant of this is shown. The inner shell 401 and the outer shell 402 of the composite profile 400 after the 2a and 2 B each have two hollow chambers 411a , 411b respectively. 412a , 412b on, the hollow chambers 412a , 412b the outer shell 402 are arranged symmetrically to each other, as well as a third hollow chamber 412c , each between the hollow chambers 411a , 411b , respectively. 412a , 412b is arranged. The hollow chambers too 412a and b become narrower from the center outwards.

In 2c is a composite profile 400 shown as preferred for an outer or continuous frame spar 41 is used. The inner shell 401 has a hollow chamber 411 on, which is rectangular here. The outer shell 402 can be a symmetrical or asymmetrical hollow chamber 412 exhibit.

It becomes clear that on the frame profiles that meet each other 41 , 42 it is provided that the outer shells of the two abutting frame bars 41 , 42 are each wider or have a larger width than the inner shells.

In 3a and 3b is an embodiment of an outer frame spar in the area of a T-connection 41 of the frame 4th shown. The continuous frame spar 41 is here from a composite profile 400 to 2c manufactured.

In 3b can be seen that on the inner shell 401 of the composite profile 400 to 2c , from which the continuous frame spar 41 is made, a connector 43 a first type has been arranged. The first design is essentially the shape of a cuboid. The connector 43 acts like a piece of a rod cut to length. However, it can have functional areas such as grooves, form-locking elements and the like, which differ from the cuboid basic geometry.

In 3b it can also be seen that on the outer shell 402 of the composite profile 400 , from which the continuous frame spar 41 is made, a connector 44 a second type is arranged. This second type is a kind of angle. The connector 44 basically builds on a base leg 44a on, the cuboid analog as the first connector 43 can be formed and also has an angled, in particular at right angles extending angle leg 444 on. Here is the connector 44 preferably like the first connector 43 integrally formed. The connector too 44 the second type can have functional areas such as grooves, form-locking elements and the like, which deviate from its angular basic geometry.

In a preferred embodiment, there are two connectors each 43 after the first design and two connectors 44 installed according to the second type. However, there can also be fewer than two each - at least one connector 43 , 44 or more than two connectors each 43 , 44 be provided. The respective connector 43 , 44 can be made of a metallic material, such as an aluminum alloy, preferably by an original molding process, such as die casting.

In 4a and 4b are two for the inner shell 401 provided connector 43 shown. The connector 43 The first type has one or more recordings 431 for glue beads and can at least take one 432 for a fastener such as a nail or screw.

Furthermore, the connector 43 at one end a foot with a T-shaped cross section 433 have, via which it in a form-fitting geometrically corresponding groove 421 in the inner shell 401 of the continuous frame spar 41 or 42 can be used (see 5c and 5d ). He can on the continuous frame spar 41 be moved to a position to be taken. It is conceivable to use a means such as the screw or nail mentioned to position this on the continuous frame spar 41 to fix.

The foot 433 and the geometrically corresponding groove lead to the fastening of the connector 43 quasi takes place in an assembly direction of an intended, abutting frame profile.

In 4a and 4b is also the one for the outer shell 402 provided connectors 44 the - also provided here in pairs - shown. The connector 44 the second type can also take multiple shots 441 for adhesive beads and at least one holder 442 for fasteners such as a nail or screw. Furthermore, the connector 44 the second type an approach 443 have, via which it in a geometrically corresponding, in particular milled groove in the outer shell 402 can be used (see 5c and 5d ). This connector can be fastened with the fastening means 44 in a first area or at one end on the outer shell 402 of the continuous frame spar 41 or 42 respectively.

The approach 443 and the geometrically corresponding groove lead to the fastening of the connector 44 quasi transversely to an assembly direction of an intended, abutting frame profile.

Both ends of the first connector engage 43 as well as the second connector 44 however, in each case in hollow chambers 411a , 411b respectively. 412a , 412b of the adjoining second frame spar 42 a like this in 6 is indicated.

In the state in which the first connector 43 and the second connector 44 on the continuous frame spar 41 are fixed, their other ends are perpendicular to the continuous frame spar 41 in front. The angle leg lies here 444 preferably parallel to the continuous frame spar 41 on this on.

The angle leg 444 engages in the assembled state of a T-connection of the frame bars 41 , 42 also with the angle leg 444 in a corresponding hollow chamber, preferably L-shaped in cross section 412 respectively. 412a , 412b the outer shell 402 of the continuous frame spar 41 abutting frame spar 42 a (see also 5 and 6 ), so that with the T-joint thus assembled, prying open with a tool in this area is at least considerably more difficult. This creates a T-connection between the frame bars 41 , 42 created with increased burglary protection.

The connector 44 second design for connecting the outer shells 402 , which has the angular basic geometry and in the assembled state with the angle leg 444 into the geometrically corresponding hollow chamber 412 , 412a , 412b the outer shell 402 of the continuous frame spar 41 abutting frame spar 42 engages, extends in this burglar-resistant to a chamber wall 412 ' which has a sealing groove on the other side 414 , 415 limited to accommodate a glazing gasket (not shown here). In this way, a good stabilization of the chamber is realized, which offers improved protection of this area against being pried open with a tool, which in turn results in improved burglary protection.

In the 2a and 2 B and 2d the outer shell is wider than the inner shell, such that there are also one or more hollow chambers 412a, b, c Extend to the side into an area that extends beyond the inner shell. This area is now also better protected against burglary because the connectors are in the corresponding hollow chambers 412a , b the outer shell protrude into this area.

In 4a and 4b are also seals 45 , 46 shown in the case of a configuration as a plate-shaped seal 45 in a rebate of the continuous frame spar 41 can be used and in the case of the seal 46 into a cavity 412c of the continuous frame spar 41 abutting frame spar 42 can be used. This is also in 5 and 6 shown.

In 5a to 5e is a pre-assembly process of the connectors 43 , 44 as well as the seals 44 , 45 shown. In 5a is a section through the inner frame spar 42 shown here from the composite profile 400 to 2d is made. Furthermore, the seal 46 shown in a first pre-assembly step in the central hollow chamber of the outer shell 402 of the profile 400 is used (see also 5b) . The seal 46 can additionally with an adhesive on the outer shell 402 be fixed.

In 5c is the outer frame spar 41 with pre-assembled connectors 43 , 44 and a pre-assembled plate-like seal 45 shown. The outer frame spar 41 is here from a composite profile 400 to 2c manufactured. In 5d this preassembled state is one connector at a time 43 and 44 and another seal 45 added. It is in 5d shown that the connector 43 and 44 also by swiveling over her foot 433 or their approach 443 into the groove provided for this purpose in the inner shell 401 or outer shell 402 of the composite profile 400 can be used, which is an advantageously simple and flexible assembly of the connectors 43 , 44 enables. The connectors 43 , 44 can, as in 5c and 5e with screws or nails on the outer shell 402 or on the inner shell 401 of the composite profile 400 be attached. 5e is the outer, continuous frame spar 41 with the connectors 43 , 44 as well as the seals 45 to 4a and 4b pre-assembled and thus ready for assembly of the T-connection with the inner frame rail 42 shown.

In 6 is the pre-assembled continuous frame spar 41 out 5e as well as the inside or adjacent frame spar 42 out 5a respectively. 5b shown ready for mounting the T-connection. Bores in the inner shell can be seen 401 and in the outer shell 402 of the composite profile 400 of the inner frame spar 42 , which are intended for fasteners such as screws or nails, with which the inner frame spar 42 about the intended recordings 432 , 442 in the connectors 43 , 44 with the continuous frame spar 41 is firmly connectable. The one in the respective connectors 43 , 44 provided recordings 431 , 441 for glue beads can be filled with glue around the two frame bars 41 , 42 to be able to glue together.

Through the angle leg 444 of the connector 44 the second type, each in the geometrically corresponding L-shaped hollow chamber 412a and 412b the outer shell 402 of the composite profile 400 of the adjoining frame spar 41 engages in each case, and which preferably extends there to a wall which adjoins a sealing groove (ie extends directly thereon or extends close to it) becomes the respective hollow chamber 412a , 412b braced. This produces an advantageously improved burglary protection of the T-connection, since this makes it considerably more difficult to pry open the T-connection with a suitable tool.

In 7 the fully assembled and assembled T-connection is shown.
