Description

The present invention relates to a door, a window or a facade element according to the preamble of claim 1.

The generic term of claim 1 DE 27 24 377 A1 and the DE 36 03 507 A1 called.

Smoke protection doors (RS) according to DIN 18095 are self-closing doors that largely prevent the passage of smoke when installed and closed. A fire protection closure, on the other hand, or in addition, has the task of securing openings in walls against the passage of fire. According to DIN 4102-5, there are the following fire and fire protection classes: T30, T60, T90, T120 and T180. The number behind the T indicates the duration in minutes, for how long the fire protection barrier prevents the fire (not the smoke) from passing through and must then still be able to be opened. Constructions are known which meet these requirements. As a rule, however, their manufacture and processing is relatively complex. In particular, the fixing of hardware components to such elements - but also to other windows or doors or facade elements - is usually still relatively complex.

Against this background, it is the object of the present invention to create a door, a window or a facade element with a frame and a casement, the fitting arrangement being easy to mount on the window or door. The invention should preferably also be particularly suitable for smoke protection doors and fire protection doors or the like.

The invention solves this problem by the subject matter of claim 1.

• ein Grundprofil, an welchem eine oder zwei oder mehr - vorzugsweise in gleicher Richtung;
• wenigstens einseitig offene Befestigungsnuten vorgesehen sind,
• wobei ein Brückenelement wenigstens einen Befestigungsschenkel aufweist, der in eine der Befestigungsnuten eingreift;
• und wobei in wenigstens einem Spalt zwischen dem wenigstens einen Befestigungsschenkel und der wenigstens einen Befestigungsnut wenigstens ein Klemmabschnitt eines Fixierelementes angeordnet - insbesondere in diesen eingeführt - ist, der den Befestigungsschenkel zumindest klemmend und optional auch formschlüssig in der Befestigungsnut fixiert, wobei das Fixierelement als ein Fixierhebel ausgebildet ist.

A window, a door or a facade element is created with a frame made of frame spars and / or with a wing frame made of frame spars, one or more of the frame spars and / or the frame spars having at least the following features:

• a basic profile on which one or two or more - preferably in the same direction;
• fastening grooves open at least on one side are provided,
• wherein a bridge element has at least one fastening leg which engages in one of the fastening grooves;
• and wherein in at least one gap between the at least one fastening leg and the at least one fastening groove, at least one clamping section of a fixing element is arranged, in particular inserted into it, which at least clamps and optionally also positively fixes the fastening leg in the fastening groove, the fixing element acting as a fixing lever is trained.

The fastening leg is fixed indirectly in this way. For this purpose, it cooperates advantageously with the fixing element, which at least clamps it non-positively in the fastening groove. Optionally, a form fit can be implemented for fixation.

It is preferred that the fastening grooves extend over the entire length of the base profile in its main direction of extension.

The invention is particularly advantageous - but not only - suitable for basic profiles on which two or more fastening grooves are provided which are open in the same direction and are each designed for fixing a corresponding fastening leg of the bridge element bridging the gap between the fastening grooves in this case. It is then expedient if the bridge element, in particular in the form of a support element for a fitting, has in a cross section essentially a U-shape with a base leg and two or more, in particular parallel, fastening legs as the longitudinal leg.

According to a variant, the invention can be implemented simply in that the preferably parallel fastening legs are spaced from one another in such a way that they engage in the fastening grooves of the basic profile and that they are designed such that the clamping section of a respective fixing element is inserted into a gap between them and at least one wall of the corresponding fastening groove.

It is then expedient if at least one of the fixing elements is provided for each fastening groove of the base profile and for each fastening leg.

The clamping section can be designed as a wedge, in particular as a linearly displaceable wedge or as a rotating wedge or as an eccentric, which can basically be regarded as a rotating wedge. An embodiment is also conceivable which is based on a combination of a rotary wedge action and a linear wedge action. In this way, a fixation can be implemented easily and securely, which can also withstand high loads.

In addition, the fixing element preferably has an actuating section which simplifies operation. This can be formed in one or more parts. It can also be designed as a manually operable handle, which makes it particularly easy to fix the bridge element.

The wedge action or eccentric action acts transversely to the main direction of extension of the basic profile, and there preferably in the direction + Y or - Y and / or in the direction + X and / or - X.

The term bridge element should not be interpreted too narrowly. The bridge element preferably bridges two of the fastening grooves, which in turn preferably lie parallel to each other and be open in the same direction. However, it may also be the case that the bridge element does not bridge two grooves and is only fastened in a single fastening groove in the manner claimed, then with only one of the fastening legs still to be discussed (hereinafter also referred to variously as longitudinal legs).

In turn, fittings, in particular fitting plates of various types, can be arranged or formed on the bridge element. The bridge element can also only take on a stabilizing function and have no fitting or wear. It then connects two fastening grooves together.

1. a) zunächst werden das Grundprofil und wenigstens ein Brückenelement und wenigstens ein Fixierelement bereitgestellt;
2. b) sodann erfolgt ein Aufsetzen des Brückenelementes auf das jeweilige Grundprofil und ein Einsetzen der Befestigungsschenkel in die Befestigungsnuten;
3. c) daraufhin wird an einem oder beiden oder mehreren oder sämtlichen Befestigungsschenkel(n) jeweils wenigstens ein Klemmabschnitt wenigstens eines Fixierelementes in einen Spalt zwischen dem Befestigungsschenkel und einer als Widerlager wirkenden Wand der Befestigungsnut eingeführt, wobei das jeweilige Fixierelement als ein Fixierhebel ausgebildet ist,und
4. d) sodann wird das jeweilige Fixierelement - vorzugsweise an einer Handhabe - in eine Fixierstellung bewegt, wobei sich der Klemmabschnitt in eine Klemmstellung bewegt, so dass der Befestigungsschenkel in der Befestigungsnut fixiert ist.

The invention also provides a method according to claim 15 for fixing a bridge element in one or more fastening grooves of a base profile of a window or a door, as described above, with the following steps:

1. a) first the base profile and at least one bridge element and at least one fixing element are provided;
2. b) the bridge element is then placed on the respective base profile and the fastening legs are inserted into the fastening grooves;
3. c) thereupon at least one clamping section of at least one fixing element is inserted into one or both or more or all of the fixing legs into a gap between the fixing leg and a wall of the fixing groove which acts as an abutment, the respective fixing element being designed as a fixing lever, and
4. d) then the respective fixing element - preferably on a handle - is moved into a fixing position, the clamping section moving into a clamping position, so that the fixing leg is fixed in the fixing groove.

The movement into the fixing position of step d) can be a linear movement or a rotary movement or a superimposed rotary and linear movement. He moves the clamping section into the clamping position in which the arrangement is fixed in the side described above, for example clamped and wedged.

In this way, it is in particular possible to simply and simply fix a fitting arrangement designed or fixed on the carrier element, which is then designed as a bridge element, to the base profile, in particular without tools.

According to a preferred variant, a fitting plate and the at least one bridge element as a support element are constructed in several pieces and fastened to one another. According to another variant, the fitting plate and the at least one support element are formed in one piece.

It is also conceivable that the bridge element does not also serve as a carrier element but only as a bridge which connects two profiles to one another, for example in order to ensure a defined distance between the profiles to be connected to one another.

Preferably, two of the carrier elements, in particular at their ends, are formed on the fitting plate, so that particularly secure fastening takes place.

According to a further variant, the functional fitting is a lock and the fitting plate is a faceplate on which the lock is arranged. According to another variant, the functional fitting is a movable or immovable pin arranged on the fitting plate.

The fitting arrangement can preferably be mounted on the base profile without tools. It is also advantageous if the fitting arrangement has a frame-like fitting cover, which can have inwardly projecting webs on its inner circumference which are designed to engage behind the fitting plate, in particular the faceplate, in order to fix it in a simple manner.

Further advantageous embodiments of the invention can be found in the subclaims.

The examples shown in Figures 5-14 are not part of the invention. Only that Figures 15-24 show embodiments according to the invention with a fixing element which is designed as a fixing lever.

Fig. 1 shows a door 1, which has a leaf with a leaf frame 2, which is arranged on a frame 3. Here, the sash 2 is rotatably mounted on the frame 3.

In Fig. 1 door 1 is shown as a swing door with door hinges. Alternatively, the door 1 can also be designed as a sliding door. Alternatively to that in Fig. 1 Door 1 shown, the present invention can also be applied to windows or facade elements. If the term door is used below, it can therefore also be replaced by the terms "window" or "facade element".

The door can be rotatable (vertical axis of rotation) and / or pivotable (horizontal axis of rotation) on the casement.

By a corner connection of vertical wing frame spars 5, 6 with an upper horizontal wing frame spar 7, the composite profile forms the at least U-shaped wing frame 2. In the wing frame 2, a surface element 8 such as an insulating glass pane or fire protection glazing or a metal or plastic sheet is used. The sash 2 and the surface element 8 together form the sash. Within the scope of this description and the claims, the term “window” also includes fixed glazing with a surface element in a frame 3.

The frame 3 of the door 1 is also U-shaped here and has a horizontal frame spar 9 and two vertical frame spars 10, 11.

The sash frame 2 and / or the frame 3 can alternatively also be formed closed all round and have further lower horizontal bars.

Some or all of the frame spars and / or sash spars have a base profile 300 (frame) or 400 (sash) with a U-shaped cross section.

The basic profile 300 and / or 400 can each be formed in one piece or in several pieces as a composite profile. A one-piece variant of the basic profile 300, 400 is shown in Fig. 1 , 2a and 2 B (here only 400) and two multi-piece variants of the basic profile 300, 400 are shown in Fig. 3 and 4th (only 400 here).

First, the one-piece variant of the basic profiles 300, 400 is off Fig.2a , b, c considered and then the multi-part variants of the Fig. 3 and 4th explained.

To Fig. 2a and 2 B each base profile 300 and / or 400 has a short leg 12 and a long leg 13. The short leg 12 and the long leg 13 run parallel to one another. They are towards their one end areas over a - preferably perpendicular to the short leg 12 and the long leg 13 - cross leg 14 connected to each other.

The cross leg 14 forms a base web of the U-shaped base profile 300, 400 and the short leg 12 and the long leg 13 form two parallel longitudinal webs of the U-shaped base profile. To Fig. 2 the short leg 12, the long leg 13 and the cross leg 14 are formed in one piece. The basic profiles 300, 400 preferably consist of Fig. 2 from a metal, in particular from a light metal or a light metal alloy, so particularly preferably from an aluminum alloy.

The long leg 13 of the base profiles 300, 400 is in a direction perpendicular to the main direction X (see 2c and 2b ) of the basic profile (i.e. in the section of the image plane of the Fig.2a ) longer than the short leg 12. The directions X and Y run in the sectional plane of the Fig. 2a or 2 B . The short leg 12 and the long leg 13 are formed parallel to one another in the X direction, while the cross leg 14 extends perpendicularly to it in the Y direction. The long leg 13 of the basic profile 400 of the casement 2 can lie on the outside of a building opening, for example on a window. Alternatively, it can also be inside. In addition, the base profile 400, 300 can also be part of a door or a window that lies completely inside the building and, for example, divides or closes off a corridor.

The cross leg 14 of the sash 2 lies in the sash 2 ( Fig. 2a , 3a , 3rd ) next to the surface element 8. In this respect, the cross leg 14 delimits the rebate space F1 between the base profile 400 and this surface element 8. A glass retaining strip 17 ( Fig. 2a , 3f ) and at least one seal 19. A further seal 66 can be arranged between the glass holding strip 17 and the surface element 8 ( Fig. 2a , 3a ). The short leg and the long leg 12, 13 are aligned parallel to one another.

The long leg 13 of the base profile 400 of the casement 2 protrudes beyond the cross leg 14 with a free end 15.

On the cross leg 14 of the base profile 300, 400, a glass retaining strip groove 16 is formed toward the outside of the rebate space F1 for fixing a glass retaining strip 17. At the free end 15 of the long leg 13, a sealing groove 18 is provided on the side facing the surface element 8 for arranging a seal 19 between the surface element 8 and the long leg 13 (see also here Fig. 2b , where the basic profile 400 has the same contours 16, 18).

Both the short leg 12 and the long leg 13 of the basic profile 300, 400 have functional contours 20, 21 arranged on their mutually facing or facing inner sides of the short leg 12 and the long leg 13, in particular, wholly or partially protruding therefrom. These functional contours 20, 21 are preferably designed as multiple functional contours that perform / realize not only one but several functions.

1. a) eine Eckverbinderaufnahmenut 20a, 21a zur Aufnahme eines Eckverbinders;
2. b) eine Befestigungsnut 20c, 21c und
3. c) eine Aufnahmenut 20b, 21b zur Aufnahme eines Vormontagesteges 22 aus.

This is how the multiple function contours are reproduced Fig. 2b :

1. a) a corner connector receiving groove 20a, 21a for receiving a corner connector;
2. b) a mounting groove 20c, 21c and
3. c) a receiving groove 20b, 21b for receiving a preassembly web 22.

It is advantageous if the functional contours 20, 21 form at least two of the aforementioned grooves a) to c). Particularly preferably, they each form three or even more of the functional grooves or at least components of this groove (s).

For this purpose, the functional contours 20, 21 each comprise at least one transverse leg 23 or 24, which projects perpendicularly from the short leg 12 or the long leg 13 (see also Fig. 2b ).

At the respective end of these cross legs 23, 24, a parallel web 25, 26 is formed, which extends parallel to the actual short leg 12 or the long leg 13, but is shorter than this. Overall, the respective cross leg 23, 24 and the parallel web 25, 26 essentially form a T-shape in cross section.

In this way, the short leg 12 or the long leg 13 as well as the one cross leg 23 or the other cross leg 24 and the one parallel web 25 or the other parallel web 26 form the corner connector receiving groove 20a, 21a.

One edge of corner connectors 4 is inserted into each of the corner connector receiving grooves 20a, 21a. It is advantageous that the two corner connector receiving grooves 20a, 21a are dimensioned so that the same corner connector 4 can be inserted into them, since this simplifies the assembly of the frame (frame and sash 3, 2).

The other edges of the two corner connectors 4 engage in further corner connector grooves 28a, b, which are delimited by short retaining webs 29, 30 protruding from the cross leg 14, the cross leg 14 and the short leg 12 or the long leg 13.

The fastening grooves 20b and 21b are formed by the parallel webs 25, 26 and on these angular webs 31, 32 formed on the mutually facing sides.

The parallel webs 25, 26 and the angular webs 31, 32 each form fastening grooves 20b, 21b which are each open to a rebate space F2 to the frame 3.

These fastening grooves 20b, 21b are preferably not designed as thread grooves for rotatingly fixing threaded elements. Rather, they are preferably designed for fixing fastening elements which preferably act in a positive and / or non-positive manner and which can be fixed by a linear movement in the fastening grooves 20b, 21b. For this purpose, the fastening grooves 20b, 21b are designed in such a way that they are U-shaped and are each open to the rebate space F2 to the frame 3. This facilitates the insertion of the fasteners into the fastening grooves 20b and 21b. Fastening elements preferably used for the fastening grooves 20b, 21b are described in more detail below. The fastening grooves 20b, 21b preferably have fixing means such as one or more Undercuts that can cooperate with corresponding fixing means such as one or more locking edges.

The receiving grooves 20c and 21c serve to receive the preassembly web 22 arranged between the receiving grooves 20c and 21c and connecting them over the length of the basic profile 300 or 400 in a bridge-like manner and in sections or preferably continuously in the Z direction. The preassembly web can be continuous in the Z direction Extend over the entire length of the base profile 300, 400 or consist of individual pieces, for example are only a few cm long and are spaced apart.

The preassembly web 22 is in the receiving grooves 20c and 21c in the main direction Z (see Fig. 2c ) of the base profile 300, 400 each perpendicular to the section plane of the Fig. 2b slidably guided. It is used in particular to form the short leg 12 and the long leg 13 during pre-assembly - that is to say when processing before assembling the frame - and in particular when cutting miter cuts on edges, and to keep the corner regions of the frames to be produced and to keep them at a defined distance during or after the pre-assembly, preferably after cutting the miter cuts. It is designed so stable that a force compressing the basic profile, as it can arise during sawing, counteracts, so that a defined distance between the ends of the short leg 12 facing away from the cross leg 14 and the long leg is maintained when the miter cuts are cut. However, it is also possible to use a web as a pre-assembly web that is not removed again, for example an insulating web.

The receiving grooves 20c and 21c are designed as preferably undercut grooves which are open on mutually facing sides - in a direction parallel to the cross leg 14.

The preassembly web 22 has a central web 22a and form-locking contours 33, 34 at both ends of the central web 22a, with which it can be inserted into the receiving grooves 20c, 21c and displaced therein. Therefore, the positive locking contours 33, 34 correspond to the cross section of the receiving grooves 20c, 21c configured so that they engage in them with little play so that the preassembly web 22 in the receiving grooves 20c, 21c (perpendicular to the image plane of FIG Fig. 2a ) is movable. In this way, the manufacture of the frame spar is optimized and simplified in a simple manner. In particular, the removable preassembly web 22 makes it possible, in a defined manner, to space the short leg 12 and the long leg 13 of the base profile 300 or 400 at their ends facing away from the cross leg 14, in order to carry out miter cuts on the base profile 400 in a simple manner with high accuracy. Before the base profiles 300, 400 are assembled into a frame, the preassembly webs 22 are then removed, so that space for other functional elements is advantageously created in this area. The pre-assembly webs can consist of different materials, such as plastic or aluminum or a combination thereof.

In Fig.3a and 3b the basic profile 300, 400 is in each case largely similar to the basic profile or the basic profiles of Fig. 2 designed. The above statements are therefore largely also on the basic profiles 300 and 400 of the Fig. 3 and 4 to 10 transferable.

However, there are also some differences, which are explained below.

So the basic profile 300 or 400 is the Fig. 3 and 4th each formed in several pieces as a composite profile.

The basic profile 300, 400 also has the Fig. 3a and 3b the short leg 12 and the long leg 13 (preferably made of metal, in particular an aluminum alloy). And the short leg 12 and the long leg 13 also run parallel to one another. They are also connected to one another via a cross leg 14, which runs preferably perpendicularly to the short leg 12 and the long leg 13, the cross leg 14 being a base web of the U-shaped base profile 300, 400 and the short leg 12 and the long leg 13 the two parallel longitudinal webs form the U-shaped base profile 300, 400.

The cross leg 14 of the basic profiles 300, 400 of the Fig. 3 and 4th but is at least as a separate insulating web 39 ( Fig. 3 ) or several insulating bars ( Fig. 4 : two parallel Insulating webs 39a, b) formed, which is / are positively and non-positively connected to the short leg 12 and the long leg 13, preferably such that a perpendicular to the plane of the Fig. 3a shear-resistant composite is formed.

At least one insulating web 39 ( Fig. 3 , 5 ) made of insulating material such as plastic or two insulating webs 39a, b ( Fig. 4 ) made of insulating material such as plastic.

The at least one insulating web 39 made of plastic can optionally alternatively have a metal base structure or individual metal webs in the plastic, which form bridges between the short leg 12 and the long leg 13 and thus optimize the statics (see, for example, the EP 1 138 864 B1 the same applicant and Fig. 3e ). In this way, the thermal insulation is locally somewhat reduced again. In this way, however, a support structure is created which, on the one hand, offers improved thermal insulation compared to the one-piece base profile 400 with one-piece cross leg 14 and, on the other hand, is so stable that it is well suited for use in fire and / or noise protection doors.

Then the short leg and the long leg 12, 13 are behind Fig. 3 or 4th not as single bars made of full metal as in Fig. 2 formed but preferably provided with at least one hollow chamber 37, 38. The short leg 12 and the long leg 13 are again made of a metal, in particular a light metal or a light metal alloy, so particularly preferably an aluminum alloy.

Even after Fig. 3 and 4th protrudes the long leg 13 over the cross leg 14 with a free end 15 or two free ends. On the cross leg 14 of the sash base profile 3, the glass retaining strip groove 16 is in turn formed to the rebate space F1 for fixing the glass retaining strip 17. At the free end 15 of the long leg 13, the sealing groove 18 is provided on the side facing the surface element 8 for arranging the seal 19 between the surface element 8 and the long leg 13.

The corner connector receiving grooves 20a, 21a can also be used to receive fire protection strips with a cooling effect, in particular in the areas of the basic profiles 300, 400 adjoining the corner connectors.

1. a) die Eckverbinderaufnahmenut 20a, 21a zur Aufnahme jeweils eines Eckverbinders 4;
2. b) die Befestigungsnut 20b, 21b;
3. c) die Aufnahmenut 20c, 21c zur Aufnahme des Vormontagesteges 22, und
4. d) jeweils eine Aufnahmenut 20d, 21d zur Aufnahme eines Kühlstreifens 65 zwischen der Eckverbinderaufnahmenut 20a, 21a und der Befestigungsnut 20b, 21b.

Both the short leg 12 and the long leg 13 have the functional contours 20, 21 on their mutually facing or facing inner sides. These functional contours 20, 21 are preferably also after Fig. 3a and b and 4th designed as multi-function contours that fulfill / realize not only one but several functions. This is how the multi-function contours form the Fig. 3 and 4th here even four functional grooves are advantageous:

1. a) the corner connector receiving groove 20a, 21a for receiving a corner connector 4;
2. b) the fastening groove 20b, 21b;
3. c) the receiving groove 20c, 21c for receiving the preassembly web 22, and
4. d) a receiving groove 20d, 21d for receiving a cooling strip 65 between the corner connector receiving groove 20a, 21a and the fastening groove 20b, 21b.

Both the corner connector receiving groove 20a for receiving the corner connector 4 and the receiving groove 20d for receiving the cooling strips 65 are each formed in the hollow chambers 37, 38 of the short leg 12 and the long leg 13. Cooling strips 65 are strips which can absorb a certain amount of fire heat or energy and / or can actively cool in the event of a fire. They can consist of a molded body which has a high heat capacity, for example of concrete. However, they can also consist of one or more shaped bodies which contain heat-binding hydrophilic adsorbent (see, for example DE 197 00 696 C. and DE 4443762 A1 ). The receiving grooves 20d, 21d for receiving a cooling strip 65 are shown in FIG Fig.3a and 3d as well as 3f and 4.

The functional contours 20, 21 include (see for example Fig. 4 ) each have a short transverse leg 23 or 24 on the short leg 12 or the long leg 13.

At the respective end of these cross legs 23, 24, a parallel web 25, 26 is formed, which extends parallel to the inner profile 12 or the outer profile 13, but is shorter than this. Overall, the respective cross leg 23, 24 and the parallel web 25, 26 essentially form a T-shape in cross section.

In this way, the inner profile 12 or the outer profile 13 as well as the one cross leg 23 or the other cross leg 24 and the one parallel web 25 or the other parallel web 26 form the corner connector receiving groove 20a, 21a.

In each case, the edges of a total of two corner connectors 4 are inserted into the corner connector receiving grooves 20a, 21a (see Fig. 2a and 3f ). It is advantageous that the two corner connector receiving grooves 20a, 21a are dimensioned so that the same corner connector 4 can be inserted into them, since this simplifies the assembly of the window and the storage. In addition, identical corner connectors can also be used both in the basic profiles 400 of the casement 2 and in the basic profiles 300 of the frame 3.

The edges of the two corner connectors 4 engage in the further corner connector grooves 28a, b, which are delimited by short retaining webs 29, 30 formed in the hollow chambers 37, 38, the transverse leg 14 and the short leg 12 and the long leg 13.

The fastening grooves 20b and 21b are delimited and partially formed by webs 40, 41 of the short leg 12 and the long leg 13, which delimit the hollow chambers 37, 38 towards the transverse leg 12 or on the sides facing one another and on these on the sides facing each other trained angular webs 31, 32.

In this way, the further (parallel) webs 40, 41 and the angular webs 31, 32 each form the open fastening grooves 20b, 21b toward the additional rebate space F2 toward the frame. These fastening grooves 20b, 21b are preferably not designed as thread grooves for rotatingly fixing threaded elements. Rather, they are preferably designed for fixing fastening elements which preferably act in a positive and non-positive manner and which are characterized by a linear Movement in the fastening grooves 20b, 21b can be determined. For this purpose, the fastening grooves 20b, 21b are also the Fig. 3 and 4th formed such that they are U-shaped and are each open to the folding space F2 to the frame 3. The fastening grooves 20b, 21b are preferably designed in the manner of simply undercut grooves. In this way, they can easily be implemented constructively on the basic profile 300, 400.

The receiving grooves 20c and 21c in turn serve to receive the preassembly web 22 arranged between the receiving grooves 20c and 21c and connecting them continuously or in sections. The preassembly web 22 is of the type shown in FIG Fig. 2b, c educated. The receiving grooves 20c and 21c are designed as undercut grooves which are open on mutually facing sides - in a direction parallel to the cross leg 14. They are formed on the mutually facing sides of the webs 40, 41.

In Fig. 4 the basic profile 400 is largely similar to that of the Fig. 3 designed. The insulating web 39, however, consists of two parallel individual webs, which are close to each other and are each positively and non-positively connected in the manner of a shear-resistant connection to the short leg 12 and the long leg 13.

Since the preassembly web 22 has been removed after the miter cuts have been made (which may have been preceded by powder coating of the base profile 400), the base profile is open between the short leg 12 and the long leg 13 on the side facing away from the cross leg 14. This is the side facing the rebate space F2, that is to the frame 3.

Fig. 2 and 3rd illustrate that it is possible to form the basic profiles 300 of the frame 3 largely identical to the basic profiles 400. Almost all of the explanations for the casement 2, which have been made above, also apply to the frame 3. The frame 3, however, has a first outer fold area F3 not pointing up to a surface element but towards a brickwork and a second fold area, which is the Folding area F2 between the casement 2 and the frame 3 is.

One difference is that in the basic profile 400 of the casement a longer web (the free end 15) is provided on the outer profile 13 than on the basic profile of the frame 3. This longer web serves to cover the surface element 8 in the edge area and around the seal 19 towards the surface element 8 ( 3f ). Towards the rebate space F2, both the base profile 400 of the casement 2 have a free end 15a on the outer profile 13 and the base profile 400 of the frame 3 in order to laterally close the rebate space F2.

At this further free (protruding) end 15a, a further seal 67 is arranged on the inside towards the fold F2 in order to seal the fold F 2. Towards the fold 2, the contours of the basic profile 300 of the frame 3 and the basic profile 400 of the casement 2 are the same, but are diagonally opposite one another.

A second difference between the basic profiles 300 and 400 of the window frame 3 and the casement 2 is that the short leg 12 and the long leg 13 are diagonally opposite one another on the built-in window or on a built-in door (see 3f ). The short leg and the long leg 12, 13 are in turn aligned parallel to each other.

It can be desired and considered advantageous if it is possible to use the open side of the U-shaped base profile 300, 400 to the rebate space F2 between the frame 3 and the sash 3 (for example after removing the preassembly profile 22) to close the visually appealing element, if possible, in order to provide dust and privacy protection to the rebate area F2 in a simple manner. In addition, a more visually appealing view of the rebate area F2 is desired than the preassembly profile 22 offers.

It is therefore advantageous if - see Fig. 5 - The open side of the basic profile 300, 400 of the casement spar and / or the frame spar lying towards the rebate space F2 is completely or partially covered with at least one or more cover elements, in particular one or more cover profile (s) 42. In this respect, it is advantageous that the fastening grooves 20b, 21b can be used to fix such a cover element or are preferably also used in the final assembly state.

The cover profile 42 preferably lies completely between the short leg 12 and the long leg 13 and is flush with these two legs 12, 13 on the side facing away from the cross leg 14. The cover profile 42 is aligned there with two transverse webs 35, 36, with which it defines one or the viewing plane E1. In this way, the free space or gap between the short leg 12 and the long leg 13 is covered in a visually appealing manner in a simple manner. This is the primary function of the cover profile. According to a preferred variant, it is not a statically load-bearing element and does not significantly increase the stability of the basic profile 400, 300 between the ends of the short leg 12 and the long leg 13 facing away from the cross leg 14. Rather, it primarily has the function of an optical cover, dust and dirt protection and possibly a fire protection function, the latter in an optional design and configuration that will be explained in more detail. Alternatively, however, it is also conceivable that the cover profile statically connects the two legs 12, 13 as a (heat) insulating element. Alternatively, however, it is also conceivable that the cover profile statically connects the two legs 12, 13 as a (heat) insulating element.

It is advantageous if the short legs 12 and the long legs 13 end in the region of the cross webs 35, 36 at the ends of the parallel webs 25, 26 outside on the common plane E1 parallel to the cross leg 14 (Y direction).

The cover profile 42 of the Fig. 5 and the following figures are each U-shaped in cross section. It has two latching feet 43, 44 (as fastening elements and as counter-fixing means to the fixing means of the fastening grooves 20b, 21b). Fig. 6a ) on, which are connected to each other by a cover leg 45 extending transversely to them. The latching feet 43, 44 each engage in one of the two fastening grooves 20b, 21b, which are open towards the rebate space F2 and have undercuts 46 for producing a latching connection. The latching feet 43, 44 can be inserted perpendicular to the transverse leg into the fastening grooves 20b, 21b. The latching feet 43, 44 are preferably designed as combined latching / clamping feet, which not only engage in a latching manner but also somewhat clampingly in the fastening grooves 20b, 21b. Nevertheless, the cover profile 42 remains easily displaceable in the fastening grooves 20b, 21b in the longitudinal direction thereof.

The latching feet 43, 44 can have a wide variety of geometries. For example, they can consist of solid material and have locking edges on the outside ( Fig. 6a ) or each of two individual webs 45a, b with latching edges which are pressed together resiliently when inserted Fig. 6b ) or be designed as hollow webs ( 6c to 6f ), which are compressed resiliently when inserted into the fastening grooves 20b, 21b.

The cover profile or profiles 42 can also be formed in one or more pieces. They also preferably consist of plastic (such as PVC, PP) or a fire protection material or a combination of these two materials. If they consist of a combination of these two materials, they preferably have a U-shaped fire protection bridge 47, to which the latching feet 43, 44 belong, and a cross bar or cover leg 45 connecting them, which forms part of the cover profile 42. The cover profiles 42 are preferably designed and designed such that pieces required by them can be cut to length in a simple manner, for example using scissors.

The cover leg 45 is preferably surrounded or covered on one of its sides or on its two sides and / or at least in corner areas with fire protection material, so that fire protection areas 48 form ( 6d) to 6d ). In this case, a covering layer 49 can be provided on the covering leg 45 towards the folding space. This can consist of any material. It is preferably designed as a hard plastic layer or plate and, for example, cast on or glued on or was formed using the co-extrusion process. The fire protection areas 48 consist of a fire protection material. This is a material that foams in the event of fire under the influence of temperature and can seal the F2 fold. The access of hot flames and / or fire gases to the rebate between the frame and the sash is thus made more difficult or completely blocked for some time (see for example the background of these technologies) DE 19700696 B4 ).

As stated, a preferably flat surface is thus realized in a simple manner toward the inside of the rebate area F2. In the longitudinal direction across the image plane the Fig. 5 the entire gap between the short leg 12 and the long leg 13 can be covered or a part of the same.

The area of a lock arrangement 50, which can be mounted on the base profile 400 in a manner to be described, is preferably not covered by the cover profile.

The Fig. 7 and 8th then illustrate another advantageous option. According to this option, 400 profile clips 51 are arranged on the base profile. For the purposes of this application, the profile clips 51 are fitting parts, since they are made of metal.

One of the profile brackets 51 is in Figure 8 pictured. This profile clip 51 has a side view of FIG Figure 8c a U-shape with a base leg 51a and two short fastening legs 51b, 51c. The base leg 51a can be provided with one or more stiffening beads. The two fastening legs 51b, c are U-shaped in themselves. They form latching sections, which are each designed to engage in one of the fastening grooves 20b, 21b. For this purpose, they have on the one hand an outwardly bent bend 52 and on the other hand a latching web 53 punched out and bent on three sides, the bend 52 and the latching web 53 each forming latching edges which are designed for the latching engagement of the undercuts 46 in the fastening grooves 20b, 21 (see e.g. Fig. 2a )). The locking edges are preferably so sharp that they cling to the fastening grooves, so that they are not displaceable in the main direction of extension of the base profile 300 or 400, but sit firmly there. In the main direction Z of the base profile 300, 400, the profile clips are preferably 10 to 50 mm long, in particular 20 mm to 40 mm. They are also set apart from one another in the main direction of extension Z, in particular at a distance of 300 to 800 mm, preferably 400 to 600 mm. They do not burn in the event of a fire and therefore stabilize the basic profile 300, 400, particularly in the event of a fire. Unlike the cover profiles 42, they are also connected to the base profile 300, 400 in a shear-resistant manner.

The base leg 51a is dimensioned so long that it overlaps the distance between the fastening grooves 20b, 21b. The profile clips 51 are preferably formed from sheet steel. This steel sheet is preferably very thin and preferably has a thickness between 0.5 and 1.5 mm. It is shaped into a stamped / bent part. Since the profile clips 51 are made of steel, they can be designed to be very stable. They are snapped into the fastening grooves 20b, 21b at a distance from one another and cut into the light metal of the base profile 300 or 400 there. In this way, they stabilize the basic profile 400 of the casement or the basic profile 300 of the frame and keep the short leg 12 and the long leg 13 at a defined distance.

The profile clips 51 are not snapped on until any miter cuts have been made on the base profile 300 or 400 and when the preassembly web 22 has been removed. In this way they cannot damage a saw or a saw blade when sawing the miter cuts. On the other hand, they have a very stabilizing effect on the profile without significantly increasing its weight. Since the fastening legs 51b, 51c of the profile clips 51 themselves are U-shaped, it is even possible to place the cover profile 42 on the profile clips 51, if they have been fixed to the base profile 400 or 300, which then lies in the area of the profile clips 51 lies above this, so that they are not visible when installed. This illustrates Figure 7a . The profile clips then lie on the inside of the cover profiles 42.

The profile clips 51 are snapped on (like the cover profiles 42), preferably in the X direction perpendicular to the cross leg 14.

At least one of the profile brackets 51 is preferably attached to the base profile 400 of the casement 2 where a fitting arrangement such as, for example, and preferably a lock arrangement 50 is to be attached. 16ff. none of the profile clips 51 are preferably provided.

On the casement, this is typically a lock arrangement 50 with a lock 54 with a cylinder and one or more movable bolts (s). The profile clip 51 or one of the profile clips 51 is vertically immediately below the Lock arrangement 50 (or another fitting arrangement) arranged so that it is additionally secured to the base profile 400 and fixed vertically.

A preferred lock arrangement 50 is shown in FIG Figure 9 pictured. This lock arrangement consists of the actual lock 54, the lock 54 having a faceplate 55 which is penetrated by one or more bolts 56.

The faceplate 55 is fixed to a bridge element or (not shown here) designed in one piece with the bridge element. The bridge element here is thus a carrier element, preferably a carrier plate. It is identified by reference number 59. The faceplate 55 preferably has one or more bores 57 through which screws or one screw 58 can pass. The screw 58 is designed in each case to engage in a carrier element 59.

Similarly, another fitting arrangement has a fitting plate which is fixed to the carrier element 59 or is designed in one piece with the carrier element.

The bridge element, in particular the carrier element 59, is preferably designed as a profile section. In particular, it is a profile section of a light metal profile, in particular an aluminum profile. Theoretically, it is also conceivable that the carrier element or the like not as a profile section but as a stamped and bent part. or to train as a casting.

The screw 58 can be screwed into the carrier element 59 for fastening the lock. For this purpose, it can also have a screw hole 60 which is also in the center.

The bridge element, in particular the carrier element 59 (see Fig. 10 ), moreover preferably and advantageously has a U-shape (in side view) with a base leg 59a and two fastening legs 59b, 59c. The two fastening legs 59b, 59c have, directly or indirectly at their ends, counter-fixing means for the fixing means of the fastening grooves 20b, 21b.

The fastening legs 59b, 59c are in turn spaced apart from one another in such a way that they can engage in the fastening grooves 20b, 21b of the base profile (400 or 300). There they are not fixed directly but indirectly.

In this respect, they are designed to engage in safety clips 61, 62. For this purpose, securing clips 61, 62 have locking edges 63, 64 at their two ends. These locking edges 63, 64 are provided at the securing clips 61, 62 with a U-shaped cross section at both ends. With them, the securing clips 61, 62 can be preassembled on the carrier element 59. After fastening the fastening clips 61, 62, the entire lock arrangement 50 can be inserted into the fastening grooves 20b, 21b, which in turn fix the lock arrangement 50 in a latching manner (for example in the manner of a so-called "hawk mouth"). The securing clips 61, 62 also form fixing elements. They are primarily resting. A further particularly advantageous variant is described below, in which the fixing elements preferably do not have a latching effect.

The securing clips 61, 62 are preferably made of plastic. In this way, a wide variety of devices, in particular the preassembled lock arrangement 50 or other fitting parts or the like, can be fixed to the base profile 400 or 300 with the securing clips. In this way, the lock arrangement 50 or another fitting arrangement with the lock 54 is securely fastened to the base profile 400 of the casement 2 in a simple manner. In addition, the lock arrangements 50 - as already described above - are fixed to the base profile 400 with the profile clips 51 or additionally secured against slipping.

The carrier element 59 or the carrier elements can also be used for the simple and preferably tool-free fixing of another element or a different arrangement than a lock arrangement on the respective basic profile 300, 400. Thus, other fitting arrangements and parts can be attached to the base profile 300, 400 simply and preferably without tools. If no fitting is arranged or formed on the carrier element 59, it merely forms a bridge element stiffening the construction.

Figure 11 shows the arrangement Fig. 7 , supplemented by a fitting cover 67 designed as a lock cover Fig. 11 a a perspective view and Figure 11b ) a sectional view of the arrangement from a). Figure 12 shows different views of the lock panel Fig. 11 . The fitting panel 67 is designed as a rectangular frame. This in turn has on its inner circumference a few small inwardly projecting webs 68, which are designed to engage behind the faceplate 55.

The faceplate 55 lies on the outside on the two crossbars 35, 36 on the base profile 400 and thus lies on the viewing plane E1. The lock panel 67 is held by the faceplate 55 because the webs 68 engage behind it. In this way, the basic profile 300, 400 is also designed in a simple manner in an optically appealing manner in the area of the lock arrangement.

Fig. 13 shows a corner area of a casement. Here is the type of lock arrangement Fig. 7 and 11 another fitting arrangement 69 fixed on the casement, which has a pin 70, 71 as a functional element, which is arranged on a fitting plate 73. This fitting plate is surrounded by a fitting cover 71 like a frame. The fitting panel 71 is in turn designed as a rectangular frame which has a few small inwardly projecting webs 72 on its inner circumference, which are designed to engage behind the faceplate 55.

The faceplate 55 lies on the outside on the two crossbars 35, 36 on the base profile 400 and is therefore on the viewing plane E1 dan. The fitting panel 71 is in turn held by the faceplate 55 since the webs 68 engage behind it. In this way, the basic profile 300, 400 is also designed in a simple manner in an optically appealing manner in the area of the lock arrangement. In addition, the fitting arrangement on the fastening grooves 20b, 21b is in turn fixed with the carrier element and preferably with a hawk mouth attachment (not recognizable here).

The Figure 15 shows in a) to f) different views of a further bridge element which is designed as a carrier element 100. The Figures 16 a) to f) then show different views of a fixing means 150, in particular for the carrier element of FIG Fig. 15 .

The fixing means 150 serves to fix the bridge element 100 to a frame spar - a base profile 300 or 400 - at least by clamping.

For this purpose, at least one fastening leg 100b, 100c is at least clamped in a fastening groove 20b, 21b. The basic profile 300, 400 can be of the type Fig. 2 or be constructed differently. It is important that it has one or two or more of the fastening grooves 20b, 21b. Preferably, this is / are fastening grooves 20b, 21b formed continuously in the main direction Z of extension.

In turn, fittings, in particular fitting plates of various types, can be arranged or formed on the bridge element 100. In this respect, the description of Figures 1 to 14 referred.

The bridge element 100 can also only take on a stabilizing function and have no fitting or wear. It then connects the two metal profiles of the base profile with the fastening grooves 20b, 21b.

It can also be provided that the grooves 20c, 21c (see Fig. 2 ) under the fastening grooves 20b, 21b as undercut grooves and to provide a connecting web - an insulating web 190 made of plastic or a web with plastic and / or metal sections - which is anchored in these grooves in a manner that is resistant to thrust, in order to provide the basic profile 300, 400 in this too Stabilize the area further ( Fig. 22 ).

Insofar as the term bridge element 100 is used in the following, this can also - but does not have to - be a carrier element or be designed as such. With regard to the options for forming or fixing fittings or the like on the bridge element, which is then also a carrier element 100, reference is made to the description of the preceding figures. The relevant configurations and explanations can also be applied to the carrier element (s) 100 in the manner of FIGS. 15ff.

To Fig. 15 ff the type of fixing the bridge element 100 is not latching but at least clamping and optionally form-fitting. The respective fastening leg 100b, 100c is preferably clamped in the fastening groove 20b, 21b. At least one fixing element, fixing element 150, is again used for fixing, or two or more of fixing elements 150 are used. Preferably, one fixing element is provided for each fastening groove 20b, 21b of base profile 300, 400. In the case of basic profiles 300 or 400 which are longer in the main direction of extension Z, a plurality of fixing elements can also be provided per fastening groove.

First, however, the bridge element 100 is Fig. 15 ff. describe.

The bridge element 100, in particular in the form of a carrier element, is in turn preferably in the form of a profile section. In particular, it is a profile section of a light metal profile (preferably produced in an extrusion process), in particular an aluminum profile. Theoretically, it is also conceivable that the carrier element or the like not as a profile section but as a stamped and bent part. or to train as a casting. It can also consist of another metal, such as steel or die-cast zinc or the like.

The bridge element, in particular the carrier element 59 (see Fig. 10 ), moreover preferably and advantageously has a U-shape (in side view) with a base leg 100a and at least two fastening legs 100b, 100c. In the main direction Z - see here Fig. 2 - Several of the fastening legs 100b, 100c can also be arranged offset to one another if the bridge element is relatively long in this direction (not shown here).

The base leg 100a can be designed as a flat web if only a bridge element stabilizing the base profile 400 or 300 is formed. The base leg 100a can, however, also have functional contours such as screw holes, latching means or vertical webs or the like, to which further elements, in particular fitting parts and the like, can be fastened (see in turn also the 1-14 ).

The fastening legs 100b, 100c are in turn spaced apart from one another in such a way that they can engage in the fastening grooves 20b, 21b of the base profile (400 or 300). There they are not fixed directly but indirectly. In this respect, they are designed to interact with one or more of the fixing means 150.

The main direction of extension of the basic profile 100b, 100c is again designated Z. The perpendicular direction Y perpendicular to the main plane of the window or door (defined by the surface element 8) is denoted by Y and the further vertical direction (in the plane of the surface element 8, but perpendicular to the main direction of extent of the basic profile 400 or 300) by X ( please refer Fig. 2 ).

One or preferably both of the fastening legs 100b, 100c has / have a width in the direction Y perpendicular to the main direction of extension of the basic profile 300 or 400, which is less than the width of the fastening grooves 20b, 21b of the basic profile 300, 400 in this direction. In this way, after the bridge element 100 has been put in place, a gap S1, S2 remains between at least one of the two or two fastening legs 100b, 100c and the respectively corresponding fastening groove 20b, 21b.

Additionally or alternatively, it is also conceivable that one or preferably both of the fastening legs 100b, 100c have a height (direction X) in the direction X perpendicular to the main direction of extension of the base profile 300 or 400 that is less than the height of the fastening grooves 20b, 21b of the basic profile 300, 400 in this direction. For this purpose, the fastening grooves 20b, 21b then require at least one undercut in this direction as an abutment. In this way, after the bridge element 100 has been put in place, there is a gap in height between at least one of the two or two fastening legs 100b, 100c and the respectively corresponding fastening groove 20b, 21b.

The respective gap S1, S2 can be used to wedge the bridge element 100 with a fixing element 150 - FIGS. 16 ff.

The fixing of the bridge element 100 in the gap S1, S2 takes place by means of the fixing element 150, which is designed, at least in sections, into the respective one Fastening groove 20b, 21b and there in the manner of a wedge element to be inserted into the corresponding gap - for example S1, S2 - in order to be moved during this movement or after the insertion movement by a fixing movement into a clamping position, in which the fixing element 150 in any case between sections At least one wall of the respective fastening groove 20b, 21b of the base profile 300 or 400 is clamped - wedged - and in which the bridge element 400 is in turn clamped in the fastening groove 20b, 21b between another wall of the fastening groove 21b, 21c and the fixing element 150 and thus is fixed.

For this purpose, the fixing element 150 preferably has at least one clamping section 151 (see Fig. 16 ). This clamping section 151 can be designed as a wedge, in particular as a linearly displaceable wedge or as a rotating wedge or as an eccentric, which can basically be regarded as a rotating wedge. An embodiment is also conceivable which is based on a combination of a rotary wedge action and a linear wedge action.

In addition, the fixing element 150 preferably has an actuating section 152 which makes operation easier. This can be designed as a manually operable handle ( Fig. 16 ).

The wedge action or eccentric action acts transversely to the main direction of extension of the basic profile 300, 400, and there preferably in the + Y or - Y direction and / or in the + X and / or - X direction.

This is because the fastening grooves 20b, 21b preferably run continuously in the main direction Z and the bridging element s100 should be secured against displacement, in particular in this main direction Z. For this purpose, a firmly fixed seat in the further directions X and Y should preferably also be achieved.

For this purpose, the fixing element 150 is preferably narrower and / or lower than the respective gap S1, S2 in the Y direction (and / or in the X direction) and in sections, at least in the clamping section 151, preferably in sections for insertion or insertion wider or higher than the respective gap S1, S2 (in an effective range). The gap can have a constant width in the direction Y or a non-constant width.

The fixing element 150 can be designed in such a way that it can be inserted into the respective gap S1 or S2 and can be moved, in particular displaced and / or rotated, into a position in which it is in the direction Y (or in the direction - Y) and / or X provides the clamping effect described above.

The latter applies in any case if the fastening groove 20b, 21b has an undercut in one of its side walls or on one of its side walls, for example a groove or groove 20b1, 20b2 or 21b1, 21b2, on which the bridge element can be supported at any point in an abutment-like manner.

First, the base profile 300, 400 and a bridge element 100 and at least one fixing element 150 are now provided (step A) (see Fig. 17a , shown without basic profile).

The bridge element 100 is then placed on the respective base profile 300, 400 and the fastening legs 100b, 100c are inserted into the fastening grooves 20b, 21b (step B).

Now at least one clamping section 151 of at least one fixing element 15β is placed on one or both (or all) of the fastening legs (100b, 100c) in a gap (area, for example S1, S2) between the fastening legs 100b, 100c and a wall of the abutment Fastening groove 20b, 21b introduced (see Fig. 17b , shown without basic profile). In the case of a fastening leg 100cb or 100c which is longer in the Z direction, it is also conceivable to arrange / provide a fixing element from two sides (Z, - Z) (not shown here).

The respective fixing element 150 is then moved / moved into a fixing position using a tool or preferably manually on the handle 152. This fixing movement can be a linear movement or a rotary movement or a superimposed rotary and linear movement. The clamping section moves in a clamping position (step c), in which the arrangement is clamped and wedged (possibly optionally with a positive fit) in the side described above.

In the following, further advantageous variants and developments are discussed by way of example.
Preferably, but not necessarily, two or more of the fastening legs 100b, 100c, if present, are fixed in the manner described above (steps a) to c), preferably in each case in an identical or analogous manner, and preferably also in the direction acting in the same direction (for example, both fastening legs 100b, 100c are preferably each moved in the same direction from the same side and pressed against an abutment (for example, in each case from FIGS. 15 ff. pressed from left to right).

In a simple embodiment (not shown here), it is possible to design the fixing element 150 as a linearly movable wedge element that is initially narrower in sections (in the Y direction) and then wider than the gap S1. If this fixing element 150 e.g. moved far enough in the main direction of extension into the gap S1, it jams in the gap S1 or S2 and presses the respective fastening leg 100b on the side facing away from the gap S1 on the side facing away from the fixing element 100 (perpendicular to the main direction of extension in - Y- Direction) against one of the two groove walls of the respective fastening groove 20b. In this way, a non-positive fixing position is created, in which the respective fastening leg 100b, 100c is non-positively clamped with the fixing element 150 in the fastening groove 20b, 21b and is thus fixed. Analog wedging and fixing can / could alternatively and / or additionally be achieved in the direction X if an undercut is formed on the fastening groove 20b, 21b, which can be used as an abutment.

After further training, also in en Fig. 15 ff can be seen, one or preferably both fastening legs 100b, 100c of the bridge element 100 have / have at least one or more projections at least on the side facing away from the fixing element 150. The at least one projection is preferably as tooth tapering at a free end. Particularly preferably, several of these teeth form a row of teeth 101 on one or preferably both of the fastening legs 100b, 100c of the bridge element 100.

The protrusion (s), in particular the tooth (s), are intended to engage in the side wall of the fastening groove 20b when the bridging element 100 is clamped with the fixing element 150, which acts as the abutment or as part of the abutment when the fixing element 150 is clamped .

For this too - and also for other reasons to be explained - it is advantageous if one or both side walls of the respective fastening groove 20b, 21b each have the groove or groove 20b1, 20b2 or 21b1, 21b2 mentioned, which are in the main direction of extension of the base profile or the fastening grooves, the groove (s) 120, 121 each forming a type of undercut in the respective fastening groove 20b, 21b.

Preferably, both of the two fastening legs 100b, 100c of the bridge element 100 each have one of the rows of teeth 101, in the same direction on the same side of the fastening legs 100b, 100c.

It is further advantageous if, according to a preferred embodiment, the at least one projection, in particular the at least one tooth or the row of teeth 101 of the respective fastening leg 100b, 100c, each in one of these grooves 20b1, 20b2 or 21b1, 21b2 in one of the two side walls of the fastening groove 20b , 21b engages, in particular engages with a little oversize. In this way, the respective fastening leg 100b, 100c and thus also the entire bridge element 100 (in a simple manner) are additionally additionally secured against lifting upwards from the basic profile and additionally against displacement in the main direction of extension in the fastening groove 20b, 21b.

It is advantageous if the fixing element 150 in the assembled state lies in the Z direction below the base leg 100a, so that a wedge effect can also be achieved upwards - in the Z direction - if a corresponding abutment is present the fastening groove 20b, 21b is also provided in this direction X. The groove 20b1, 20b2 or 21b1, 21b2 is suitable for this.

After the Figures 16 ff. the fixing element is designed as a fixing lever. This fixing lever has a first, here short lever arm 153 and a second, here long lever arm 154 oriented at an angle 90 °> = α> = 5 ° thereto. A toggle-like configuration is realized. The short lever arm 153 is designed as the clamping section 153. And the long lever arm 154 is configured as the operating section 152.

The short lever arm 153 has a non-circular shape. It is designed in such a way that it can be pushed into the gap between one of the fastening legs 100b, 100c and one or more of the walls of the fastening groove 20b, 21b.

The short lever arm 153 acts as a rotating wedge. This means that it is rotated about an axis of rotation so that a wedge effect for jamming the corresponding respective fastening leg 100b or 100c and thus the bridge element 100 is generated.

The short lever arm 153 has a type of projection on the side in the manner of a pin 155. This pin 155 is preferably designed as an eccentric. The pin 155 is a functionally very advantageous part of the clamping section 151 in this embodiment (but not in every embodiment according to the invention), since it essentially realizes the clamping of the fastening leg 100b, 100c here. The pin 155 is therefore designed to engage in the groove 20b1, 20b2 or 21b1, 21b2 and to be rotated therein.

After the insertion of the bridge element 100, the fixing lever is guided into the fastening groove on the side of the bridge element 100. Then it is moved in the main direction of extension. The clamping section 151 or the short lever arm 153 is pushed into the gap S1 or S2 between the respective fastening leg 100b or 100c and the fastening groove 20b or 20c. The pin 154 is pushed into the groove 20b1, 20b2 or 21b1, 21b2.

Since the pin is (somewhat) longer in one direction than the height of the corresponding groove 20b1 and is flatter in one (somewhat), it can be oriented in an orientation ( Fig. 17a , b are inserted into the fastening groove. He projects with the lever arm from the fastening groove 20b, 21b in such a way that the long lever arm 154 can be gripped as a handle. If the lever arm 154 is now rotated in the direction of the base of the respective fastening groove 20b, 21b, the short lever arm acts like a toggle lever and there is a rotation and then after a certain angle of rotation the pin 155 is jammed in the groove 20b1, 20b2 or 21b1, 21b2 in the direction X (in height).

The pin 155 additionally has at its free end on the end face an inclined surface 156 which is designed like a wedge and can act like a rotating wedge. An abutment is required in correspondence with this configuration. This should be designed in such a way that the short lever arm as a whole is pressed when rotating through the inclined surface in the fastening groove in the direction of the adjacent fastening leg 100b and presses it in the direction Y against the side wall of the fastening groove 20b.

To implement this abutment, it is again advantageous if the respective groove 20b1 also has a corresponding, oppositely oriented wedge surface K1 (see, for example, FIG Fig. 21 ) having. This can be achieved, for example, in that the groove 20b1, 20b2 or 21b1, 21b2 has a triangular cross section and / or that it tapers towards the bottom of the respective fastening groove.

The orientation of these wedge surfaces / inclined surfaces 156 and K1 is such that these inclined surfaces when the fixing lever is turned from the insertion position ( Fig. 17b ) slide together in the fixing position. As a result, the pin 155 and thus the clamping section 151 of the fixing element 150 are laterally displaced in the direction -Y and thus in the direction of the fastening leg 100b of the bridge element 100.

This in turn presses the attachment leg 100b or 100c against the opposite side wall of the attachment groove. The row of teeth 101 is pressed into the opposite groove 20b2. Overall, such a firm jamming and tensioning and also a positive locking of the fastening leg 100b, 100c (and also the fixing lever) is achieved in all three spatial directions X, Y, Z.

Adjacent grooves remain completely or essentially unaffected. For example, non-adjacent grooves 20b, 21b deform to accommodate, for example, an insulating web 190 ( Fig. 22 ), which can advantageously be arranged under the bridge elements 100.

Such fastening can take place on both fastening legs 100b, 100c from one side or even from two sides.

As already discussed, the short lever arm 153 of the fixing element 150 is pushed into the gap S1 or S2 to fix the one or both fastening legs 100b, 100c ( Fig. 17a ). In this situation, the long lever arm 154 projects obliquely from the fastening groove 20b, 21b. The long lever arm 154 is preferably so long, for example more than 30 mm long, that it can be moved as a manual handle without tools. It is also conceivable to design the long lever arm 154 such that it can be moved in addition or only with a tool. The configuration in such a way that manual handling is possible is preferred.

For the actual fixation, the inserting process is followed by a fixing rotary movement. To do this, the long lever arm 154 is moved into the fastening groove, i.e. rotated until it lies in it and preferably no longer protrudes from it.

The short lever arm 153 is preferably dimensioned such that it is in one position ( Fig. 17a ) can be threaded into the fastening groove in the main direction of extension, but that it has an eccentric shape which allows the fixing element to be jammed in the fastening groove. For this purpose, it is preferably provided that the short lever arm rotates around the pin 155 as a pivot bearing, it then jamming due to its eccentric shape. In particular, the elongated pin 155, the longer dimension of which is greater than the height of the groove 20b1, is preferably jammed in the bottom surface thereof. In this way, an additional positive connection in the Z direction is achieved.

Fig. 23 shows a perspective view of a section of a basic profile 300, 400, a support element 100 attached to it and a fixing lever 150 in a position not yet fixed. Fig. 24 finally shows a perspective view a section of a basic profile designed as a sash frame spar with a functional fitting attached to it, which is designed here as a lock with a lock cover (fitting cover 71). The bridge element 100 - then as a support element - is excellently suitable for fixing it and for fixing other functional elements or fittings. <b> reference number </b> door 1 Casement 2nd Frame 3rd Corner connector 4th Casement spars 5, 6 Casement spar 7 Surface element 8th Frame spars 9, 10, 11 Short leg 12 Long leg 13 Cross leg 14 Free end 15, 15a Glass retaining strip groove 16 Glass holding strips 17th Sealing groove 18th poetry 19th Functional contours 20, 21 Corner connector receiving groove 20a, 21a Mounting groove 20b, 21b Groove 20c, 21c Groove 20d, 21d Pre-assembly bar 22 Crossbar 23, 24 Parallel web 25, 26 Groove 26, 27 Corner connector grooves 28a, b Footbridges 29, 30 Angle bars 31, 32 Form-fitting contours 33, 34 Crossbars 35, 36 Hollow chamber 37, 38 Insulating bars 39, 39a, 39b Walkways 40.41 Cover profile 42 Locking feet 43, 44 Cover leg 45 Undercuts 46 Plastic bridge 47 Fire protection area 48 Cover layer 49 Lock arrangement 50 Profile brackets 51 Base leg 51a Mounting leg 51b, 51c Angling 52 Rest bridge 53 lock 54 Faceplate 55 bars 56 drilling 57 screw 58 Carrier element 59 Base leg 59a Mounting leg 59b, c Thickening 59d, e Screw hole 60 Safety clips 61, 62 Locking edges 63, 64 Cooling strips 65 poetry 66 Fitting cover 67 Walkways 68 Fitting arrangement 69 Cones 70 Fitting cover 71 Walkways 72 Fitting plate 73 Carrier element 100 Base leg 100a Mounting leg 100b, c Thickening 100d, e Gutter 120, 121 Rows of teeth 101 Fixing element 150 Clamping section 151 Operating section 152 Lever arm 153 Lever arm 154 Cones 155 Sloping surface 156 Basic profile 300, 400 Folding rooms F1, F2, F3 level E1 gap S1, S2 angle α Wedge surface K1
