EP3080375B2 - Device for closing an opening in a building - Google Patents

Description

The invention relates to a device which comprises a frame and a flat closure element and is used to close a building opening, the flat closure element and/or the frame rigidly attached to the edge of the building opening having a frame profile which has a hollow space open towards the rebate area on three sides includes.

In this document, the word "fold surface" means the surfaces aligned at least approximately normally to the plane of the flat closure element, on which flat closure elements face one another or flat closure element and frame face each other when the wall opening is closed.

A "flat closure element" within the meaning of this document is typically a window sash or a door sash, regardless of the way in which its mobility is guided, for example regardless of whether the door is a pivoting door, folding door, sliding door, sectional door, sliding folding wall, etc.

The writings DE19509206 A1 , DE19931171 A1 , DE29812574 U1 , EP1020605 A2 and DE19733415 B4 show wings of pivoting doors or windows designed as so-called "all-glass wings". In this case, two glass panes arranged parallel to one another at a distance from one another are bonded to one another with the interposition of a spacer profile running along the edge of both panes. Furthermore, the side of the spacer profile that remains exposed is provided with a so-called fitting groove.

A so-called "fitting groove" (a standardized version of which is also sometimes called "Eurogroove" in professional circles -) is known above all in window frame profiles. It is a shallow groove, which can have an opening surface narrowed by projections from the groove flanks. The fitting groove is used to guide push rods in turn/tilt and turn windows and to facilitate the positioning of fittings or bores and cut-outs for this in the directions normal to the window plane. In general, it is not used to make drilling and milling work superfluous.

the DE 198 60 217 A1 shows a swing door to be used as a front door, in which the door leaf consists of a rectangular plate-shaped core made of an insulating material, a metal profile frame, for example, and two cover layers, the profiles of the profile frame having a groove open towards the rebate surface. The profile frame runs around the end faces of the core. The cover surfaces run parallel to their common plane on both sides of the core and profile frame and are glued to both the core and the profile frame so that a stable sandwich is formed. On the opening surface of the groove of the profile frame, which is open towards the rebate surface, a short profile wall aligned normal to the groove flanks protrudes from each of the two groove flanks. As intended, hinge fittings or a lock can be fastened in said groove. The profile walls protruding from the groove flanks presumably serve as a fastening aid. On the underside of the door leaf, the groove is covered with a cover strip to prevent dirt from entering. Probably to achieve high stability of the swing door proposed for use as a front door, the profiles of the profile frame are very large and covered by the cover layers of the door leaf and glued to it. However, the construction is not sufficiently stable for use as fire protection doors that can be closed and opened automatically.

Also the GB 2478754A shows a swing door in which the door leaf consists of a rectangular plate-shaped core and a metallic profile frame and two cover layers, the profiles of the profile frame having a groove open towards the rebate surface. The profile frame runs around the end faces of the core. The cover surfaces run parallel to their common plane on both sides of the core and profile frame and are connected both to the core and to the profile frame, so that a sandwich is formed. At the opening surface of the groove of the profiles of the profile frame, which is open towards the rebate surface, a short profile wall aligned normal to the groove flanks protrudes from each of the two groove flanks. For the purpose of mounting fittings on a profile, a forend plate and a clamping part are fastened to the projecting profile walls by bridging the distance between the projecting profile walls, abutting against the projecting profile walls from opposite sides, and by means of one or more screws with the projecting profile walls interposed are drawn.

The forend plate is connected to the fitting, typically by screws. The contact surfaces of the forend plate and the clamping part with the projecting profile walls of the profile are essentially only parallel to the planes of the forend plate and the clamping part. As a result, the connection between these parts with the profile holds positively only in the direction normal to the plane of these parts. In all other directions, the connection is only friction-locked. This is not enough, at least for doors that are subject to high mechanical stress and where reliable function is safety-relevant.

High mechanical stress on a swing door does not only occur because of its weight or if it is supposed to withstand a burglary. An extreme application in terms of the frequency of occurrence and the difficulty of the mechanical stresses relates to swing doors which, for safety reasons, must have an automatic closing and opening mechanism, as is typically the case with fire doors, in particular with double-leaf fire protection doors. The strongest mechanical stress on such doors is that they have to perform five hundred thousand to one million automatically triggered opening and closing cycles without interruption during standard tests without even a single part or a single connection failing so much that the function is no longer reliable given is. (The exact number of test cycles depends on the country-specific standards). Double-leaf swing doors used as fire protection doors not only have a closing sequence control that must ensure that the overturning leaf (active leaf) is always safely closed after the sash is hidden (fixed leaf), but also an opening sequence control that must ensure that when the fixed leaf is opened, this must also be the case the active leaf is opened at least up to the minimum opening angle from which it is ensured that the closing sequence control works reliably. In particular when testing the opening sequence control, in which the passive leaf is opened by an external actuating device and the active leaf is therefore automatically opened at least up to the said minimum opening angle by a transmission mechanism built into the door, there are unfavorable lever ratios (near the dead center) in some opening angle ranges at individual points Extremely high forces can also be exerted on hardware components for a short period of time.

Exactly with such doors many fittings are to be attached in and on the frame and on the wings, so that a quick, easy and flexibly adjustable mountability of fittings in profile grooves without the need for separate holes or cutouts would be economically very desirable. However, due to the difficulties arising from the mechanical requirements described, this has not previously been possible in a satisfactory manner.

• Der zur Falzfläche hin offene Hohlraum soll eine derart große Querschnittsfläche aufweisen können, dass alle erforderlichen Beschläge darin Platz finden können, ohne dass dafür am Rahmenprofil gebohrt oder gefräst werden muss.
• Die Bauweise soll derart hohe mechanische Festigkeit erlauben, dass dementsprechend auch Schwenktüren mit hoher mechanischer Beanspruchung wie insbesondere Brandschutztüren mit automatischer Öffnungs- und Schließfolgeregelung dementsprechend gebaut werden können und zwar auch ohne dass es dazu erforderlich ist, aus Rahmenprofilen und Deckflächen eines Türblattes ein Sandwich zu bilden.

The main object on which the invention is based is to propose a construction for a closable building opening designed as a window, door or gate, with the movable closing element or elements and/or the frame rigidly attached to the edge of the building opening having a frame profile whose cross-sectional area is a cavity open to the rebate area on three sides. Compared to known constructions in which such a cavity occurs, the construction to be created - with good economic efficiency and without having to accept optical disadvantages - should enable the following combination of improvements:

• The hollow space open towards the rebate surface should be able to have such a large cross-sectional area that all necessary fittings can be accommodated therein without having to drill or mill the frame profile.
• The design should allow such high mechanical strength that swing doors with high mechanical stress, such as in particular fire protection doors with automatic opening and closing sequence control, can be built accordingly, without it being necessary to form a sandwich from frame profiles and cover surfaces of a door leaf .

An important secondary task is that the amount of work for the production of the movable closure elements and the frames should be low. These tasks are solved by a device according to patent claim 1.

In order to solve the tasks, a design is assumed in which a frame profile delimits a cavity open towards the rebate surface by three boundary surfaces which are arranged in an approximately U-shaped manner in cross-section with respect to one another, with the profile wall protruding from the two lateral boundary surfaces, which has the width of the cavity in a cross-sectional view locally narrowed, whereby fittings can be attached to the projecting profile walls with the aid of a clamping part by the projecting profile walls being clamped in between and the clamping part and fitting part bridging the cavity between the two projecting profile walls.

As an improvement according to the invention, it is proposed to design the connection between the clamping part and the projecting profile walls in such a way that it blocks relative movement between the projecting profile walls away from one another and towards one another in a form-fitting manner. In order to create this positive blocking, the contact geometry between the projecting profile walls and the clamping part is designed in such a way that the clamping part rests against the two projecting profile walls on both flanks of a groove which is formed on each of the projecting profile walls and whose opening surface is parallel to the connecting surface between the two projecting ones Profile walls is located, and wherein an abutting in the groove area of the clamping part has a toothing on the contact surface with the groove. Said groove is designed on the protruding profile walls in such a way that the distance between its flanks in that area on which the clamping part rests decreases as the depth of the groove increases. In this way, a play-free form fit between the frame profile and the clamping part can be achieved in a particularly simple and reliable manner.

In a further particularly preferred embodiment, the cross-sectional area of the frame profile has no closed hollow chambers. Advantages that can be achieved in this way relate to manufacturability, fire protection and the ability to be connected to parts which are arranged on the side of the frame profile applied from the opening side of the cavity.

The importance of the invention is mainly based on the many applications in which the invention construction brings considerable advantages or which are made possible in the first place by the construction according to the invention, clearly, in addition to the basic principle of the invention, some such exemplary applications are therefore also outlined and described below.

Apart from individual fitting attachments that may be shown, the devices fall in accordance with the drawings Fig.6 and14 to 16 and 20 not covered by the present claims. These drawings and the associated descriptive text only serve to facilitate the understanding of the invention by also treating devices which, although not per se falling under the present claims, can be combined particularly advantageously with a device according to the present claims.

1 shows the mutually facing area of two pivoting door leaves which, apart from the fittings, are formed from a glass pane 32 and a frame comprising frame profiles 1 and glazing beads 31 enclosing it.

The frame profile 1 is typically formed from sheet steel by roll forming. Details of the frame profile 1 are partly in 2 better recognizable than in 1 . It has a substantially U-shaped cross section and as such encloses the profile cavity 2 on three sides in a cross-sectional view, with the open side of the profile cavity being oriented towards the rebate surface in the case of FIG 1 So to the other frame profile 1 out.

in the in 2 illustrated. For example, the glass pane 32 of each pivoting door leaf is held on the frame profiles 1 by being clamped along their edges between two glazing beads 31 with an elastic sealing profile 33 interposed. The glazing beads 31 are also profiles, which typically are formed by roll forming and seam welding a strip of steel sheet. The glazing beads 31 are each on the outside of the base surface 3 ( 2 ) of a frame profile 1 and are connected to the frame profile 1.

Typically, the connection between a glazing bead 31 and a frame profile 1 is formed by screws extending from the cavity 2 of the frame profile 1 through its base surface 3 and through the adjacent wall of the glazing bead 31 into the profile cavity of the glazing bead 31 . A secure and detachable connection is thus formed without fastening elements being visible from the outside. For reasons of space and ease of handling, it proves to be advantageous that the frame profile 1 is not a hollow profile.

Close to the opening surface of the cavity 2 jumps at the same level above the base surface 3 of the frame profile 1 from each of the two lateral surfaces 4 ( 2 ) of the frame profile 1, a profile wall 5 protrudes towards the cavity 2 so that the width of the cavity 2 in the height area of the two profile walls 5 is narrowed compared to the width in adjacent height areas,

1 also shows the assembly according to the invention of a fitting 19 in a frame profile 1, the fitting 19 being a lock case in this example. The fitting 19 is essentially arranged in the cavity 2 . It is rigidly connected to a forend plate 17 , which rests against the profile walls 5 on the side of the profile walls 5 facing away from the base surface 3 of the frame profile 1 and thereby covers the cavity 2 .

A clamping part 11 rests against the profile walls 5 on the side of the profile walls 5 facing the base surface 3 of the frame profile 1 . The head of a screw 16 rests against the outer side of the forend plate 17 . The threaded bolt of the screw 16 runs through a hole in the forend plate 17 and is provided with a threaded hole in the middle part 12 ( 3 ) of the clamping part 11 in threaded engagement. Due to the tensile force exerted by the screw 16, the forend plate 17 and the clamping part 11 are pressed towards one another. Against movement towards each other are cuff plate 17 and clamping part 11 by dis profile walls 5 on which they rest supported, so clamping part 11 and cuff plate 17 from opposite sides. Compressive force on each projection 10 ( 2 ) of the profile walls 5 which, in total, is the same as the tensile force of the screw 3.

It is of essential importance according to the invention that the contact surfaces between the clamping part 11 and profile walls 5 of the frame profile 1 are not simply flat surfaces aligned normally to the screw 16, but that the clamping part 11 with its two edge regions 13 each on both flanks of a groove 6 ( 2 ) rests, whose groove base is on a profile wall 5 and whose opening surface is aligned with the base surface 3 of the frame profile 1 and whose width at the contact area with the clamping part 11 increases continuously from the groove base to the opening surface.

This construction ensures that the clamping part 11 represents a secure, play-free and form-fitting blockade against relative movements of the two side surfaces 4 of the frame profile 1 towards and away from one another. This effect is reinforced by the fact that the forend plate 17 is also held in a form-fitting manner against lateral displacement in relation to the frame profile 1, in that a wall area of a profile wall 5 rests frontally on both lateral end walls of the forend plate 17, since the forend plate 17 is attached to the profile walls 5 in each case a corner region 7 rests against which a surface lying parallel to the base surface 3 of the frame profile 1 merges into a surface lying approximately normal to the base surface.

The frame profile 1 shown would be relatively easy to deform on its own in such a way that its two side surfaces 4 are bent towards or away from one another. This softness is corrected by the described arrangement of clamping parts 11, so that the frame profile 1 is similarly stiff and solid as a closed hollow profile in those longitudinal areas on which clamping parts 11 are arranged.

The invention thus makes it possible to provide light and slim frame profiles 1 for doors with extremely high mechanical requirements, which have a cavity 2 open towards the rebate surface in which fittings 19 can be conveniently attached and which are also single-walled, i.e. without a hollow chamber , so that they are easy to manufacture and, if necessary, easy to process. It is only necessary to mount clamping parts 11, as shown, in those longitudinal areas of the frame profiles 1 where high mechanical loads are to be expected. If necessary, a forend plate 17 can also be used as a complementary part to a clamping part 11, which is not connected to a fitting 19, but is simply just a plate that comes from the side opposite the clamping part 11 due to the force of screws 16 on the profile walls 5 presses.

in the in 1 In the advantageous embodiment illustrated, the fitting 19 is held in addition to its holder on the forend plate 17 by a plate 27 against movement normal to the frame formed from the frame profiles level. For this purpose, the plate 27 is clamped between profile walls 9 , which project from the base surface of the frame profile 1 into the profile cavity 2 , and the fitting 19 is inserted into a cutout in the plate 27 .

As in 3 As can be seen, the protruding edge areas 13 of the clamping part 11, with which this is intended to rest in grooves 6 of the frame profile 1, are equipped with teeth 14 in such a way that when the clamping part 11 is arranged as intended on a frame profile 1, on the contact surface of an edge area 13 with boundary surfaces of the Groove 6 in the profile direction of the frame profile 1 Alternating elevations and depressions. The force with which the toothing 14 of the clamping part 11 is pressed into the groove 6 presses the tips of the toothing into the material of the frame profile 1, whereby the clamping part 11 is held on the frame profile 1 in a form-fitting manner, also preventing it from slipping in the profile direction.

4 shows a design of a clamping part 103, the edge areas of which are intended to be brought into engagement with a frame profile and are rounded off at diagonally opposite end areas. The clamping part 103 is easier to assemble than the clamping part 11, since the intended installation in the profile cavity of the frame profile in question only needs to be pivoted about the axis of its threaded bore and not about an axis normal thereto. This is particularly important when other objects are already placed in the profile cavity, so that there is little space.

figure 5 shows an exemplary corner angle 104 for connecting two frame profiles according to the invention via a miter surface in an oblique view. The two legs of the corner angle 104 are like the forend plate 17 according to 1 to be applied to the profile walls of the frame profile to be clamped and to be pressed against the relevant profile walls by means of clamping part 11, 103 and screw 16. In contrast to the forend plate 17 from 1 the legs of the corner bracket 104 rest only on the longitudinal areas of the relevant profile walls adjoining the miter surfaces. The corner connection is easy to assemble and very stable.

At the in 6 sketched non-inventive installation of a fitting 19 in a frame profile 1, the faceplate 106 connected to the fitting 19 does not lie directly on the frame profile 1, but using an intermediate insulating layer 105 made of a heat-insulating, preferably also heat-resistant, material.

In 7 is outlined as an example of how a frame profile 1 not designed according to the invention can be used as a slide rail for a slide block 62 of a slide rail door closer.
According to the functional principle of slide rail door closers, which is known per se, a sliding block 62, which is mounted so that it can be displaced linearly along the upper part of the door frame (formed by a frame profile 1), is connected via a pivoting arm 64 to a rotary drive 65, which is held stationary at the upper edge of the pivoting door leaf and which exerts a torque on the pivoting arm 64 about an axis parallel to the pivot axis of the door leaf. (The reverse construction is also possible, according to which a sliding block mounted linearly displaceably along the upper edge of the door leaf is connected via a pivoting arm to a rotary drive anchored in a fixed position on the upper part of the door frame.) A construction as in 7 outlined, a frame profile 1 designed according to the invention can take over the function of the slide rail, which would otherwise have to be designed as a separate part. For this purpose, the sliding block 62 extends between the profile walls 5 ( 2 ) and it is provided on each of its two side surfaces with a groove into which a projection 10 of a profile wall 5 protrudes, so that the grooves on the sliding block 62 act as sliding guide grooves for which the projections 10 are the complementary parts.

For reasons of assembly, it is advantageous to form the slide 62 as outlined in two parts, both of which only extend slightly over half the width of the fitting groove and are only connected by means of screws 63 during assembly on the frame profile 1.

In consistent application of the present invention is according to 7 the rotary drive 65 of the slide rail door closer, on which the second end of the swivel arm 64 is held, is also held in the cavity of a further frame profile 29 according to the invention. The attachment of the rotary drive 65 in the frame profile 29 is the same as that of the fittings 19 of. 1 with the help of clamping parts 11, a forend plate 17 connected to the rotary drive 65 and by means of screws which forend plate 17 and clamping parts 11 press against one another so that they clamp part of the profile walls protruding from the side walls of the frame profile 29 between them. The frame profile 29 forms according to the example 7 the upper frame portion of a swing door leaf. In this way, a visually extremely inconspicuous construction of a slide rail door closer is realized. There is no need to use a separate slide rail. In addition, very simple assembly is possible, and in addition there is very good adjustability with regard to the position of the rotary drive 65 along the associated frame profile 29 .

In 7 a possibility is also outlined as to how adjacent frame profiles 29 of a door leaf frame or a frame can be connected to one another. Two so-called corner clamping brackets 25, 26 are provided for this purpose. These corner clamping brackets 25, 26 each consist of two identical profile legs connected to one another at an angle of 90°. The cross-sectional areas of the profile legs are dimensioned such that they can be inserted into an undercut groove on the frame profile 29, forming a press fit, so that they are stuck there without play. in the in 7 In the advantageous embodiment illustrated, the base surface of each undercut groove forms the inner side of a side wall of the frame profile 29. The corner clamping brackets 25, 26 are secured against movement away from this base surface on the one hand by a profile wall 9 protruding from the base surface of the frame profile 29 and on the other hand by that profile wall 5 held, on which the clamping part 11 rests, which for the inventive attachment of fittings in the frame profile 29 serves.

The frame profile 29 according to 7 differs from the frame profile 1, which has mainly been discussed so far, in that it has a profile wall 30, which protrudes from the side of the base surface facing away from the cavity and can assume the function of a glazing bead, so that only a single separate glazing bead 31 is required for each frame section.

8 shows - among other things - the inventively designed connection of hinge parts on a swing door leaf and the associated, stationary frame. Frame profiles 1 form the door frame. Frame profiles 29 (with a molded profile wall 30, which serves as a glazing bead) form the frame of the pivoting door leaf designed as a glass leaf. The axle journal 34 about which the pivoting door leaf can be pivoted relative to the frame is located in front of the space enclosed by the frame profiles 1 . Supporting arms arranged one above the other protrude from the axle journal 34 into the near rebate area between the pivoting door leaf and the frame and are connected there by means of screws 16, each with a face plate 36 and a clamping part 35 on the frame profile 1 and 29, respectively. Because of this. If particularly high loads are to be expected, the forend plates 36 and the clamping parts 35 each have two connecting screws 16 to one another and not just one like the forend plates 17 and clamping parts 11 in the examples discussed above. In this case, too, the arrangement is optically unobtrusive, easy to assemble and can be detachably fastened at any desired position along the longitudinal direction of the frame profiles 1, 29 without the need for any drilling or milling.

8 also shows how the frame profiles 1, 29 can be "upgraded" to have improved beach protection properties.

A heat shield 38 is clamped on the respective left side of the respective cavity of the frame profile 1, 29. In this case, it has the shape of a flat U-profile, with the free legs resting against the respective side wall of the frame profile 1, 29 and the base of the flat U-profile is therefore arranged at a distance from the respective side wall of the frame profile 1, 29 . The free ends of the legs of the U-profile, which forms a heat shield 38, are preferably provided with teeth so that they are not in line contact with the frame profile 1, 29, but rather with a series of point contacts, since there is thermal conduction between the two parts is reduced. The heat shields 38 are primarily used to prevent thermal radiation from one side surface of the cavity 2 of the frame profile 1, 29 to the other side surface. What is particularly advantageous about the illustrated embodiment is that the heat shields 38 can also be inserted and clamped into the frame profiles 1 subsequently from the open side of the cavity 2--that is, from the rebate surface.

A fire protection body 37 is inserted in each case on the right-hand side of the respective cavity of the frame profile 1, 29.

This fire protection body 37 has the shape of a rectangular profile. It consists of a heat-resistant, heat-insulating material, for example based on mineral wool or silicate. In contrast to the heat shield 38, it not only keeps heat radiation away but also brakes heat conduction to a very great extent.

By arranging different types, different strengths and different numbers of heat protection objects in the hollow chamber 2 of a frame profile 1, 29, the frame profile 1, 29 can easily be modularly adapted to different fire protection classes such as F30, F60, F90 etc. This results in economically very valuable advantages in terms of manufacturing and assembly logistics.

In order to jam fire protection body 37 and heat shield 38 against movement normal to the plane of the frame formed by frame profiles 1, 29, fire protection body 37 and heat shield 38 are each clamped between a side surface of frame profile 1, 29 and other profile walls, with one of these other profile walls being the base surface of the frame profile protrudes inwards; on frame profile 1 this is profile wall 9.

In the frame profiles 1, 29, heat conduction can only occur directly through the base surface 3 ( 2 ) from a side face 4 ( 2 ) on the other. Side surface 4 done. This heat conduction can be slowed down considerably by using the base surface 3 as in 2 clearly recognizable, provided with a grid of openings 8, so that the cross-sectional area for heat transfer by thermal conduction in the material of the frame profile 1 is reduced and the transmission path is extended. It is particularly advantageous if the openings 8 are oblong holes, as shown, the longitudinal direction of which is parallel to the profile direction, and if several rows of oblong holes are offset next to one another by half a grid dimension.

For the production of the openings 8 it is very advantageous that the frame profile 1 has a simple base surface 3 and not several base surfaces which enclose one or more hollow chambers. As a result, the openings 8 can be formed simply by punching. In the case of hollow chambers, milling would have to take place instead, which means much longer processing times and much higher costs.

9 shows in two views an advantageous construction for connecting two frame profiles 1 that can be used according to the invention with a miter in order to form a frame for a door surface or a window surface. A corner clamp fitting 44 is used for this purpose, which consists of four different components:

The support bracket 45 consists of two flat rectangular pieces of sheet metal, which are connected to each other along a short end face and are at right angles to each other. The support bracket 45 rests in the cavity of the frame profiles 1, which are in mitred contact with one another, on the base surfaces 3 thereof.

On the support angle 45 is another angle, the so-called traction angle 46 on the outside. It also essentially consists of two flat sheet metal rectangles which are connected to one another along their short end faces and are at right angles to one another. The lateral end faces of the pulling angle 46 are equipped with teeth 47, the tips of which bear against a profile wall 9 of a frame profile 1.

A screw 50 passes through a nut-threaded bore in pull bracket 46 . Said nut thread hole runs through the pulling angle 46 and is diagonal to both of its legs. The screw 50 presses with its end face, which is inner with respect to the pulling angle 46 , to the boundary area between the two angle legs of the inner support angle 45 . When screwing further towards the support bracket 45, it causes the pull bracket 46 to be pulled away from the support bracket 45 approximately diagonally.

Expansion bolts 49 are rigidly connected to the legs of the support bracket 45 . They have approximately the shape of a circularly symmetrical mushroom and protrude from the legs of the support angle 45 into the raised angle area between these legs and each run through an elongated opening 48 running in the direction of the legs on the respective adjoining leg of the traction angle 46 . The width of the opening 48 decreases with increasing distance from the connecting surface between the two legs of the pulling angle 4, it also becomes narrower than the diameter of the expansion bolts 49 in their longitudinal area running through the opening 48.

By screwing in the screw 50 towards the support bracket 45, the legs of the pull bracket 46 on the support bracket 45 are shifted towards the connecting line between its legs. As a result, longitudinal areas of the opening 48, where the width of the opening is less than the diameter of the longitudinal part of the expansion bolt 49 running through the opening when the tension angle 46 is not deformed, reach expansion bolts 49 Parts of the pulling angle 46 are spread apart and the teeth 47 are pressed firmly against the profile walls 9 of the frame profiles 1 and thus the frame profiles 1 with the pulling angle 46 are shifted relative to the support angle 45 onto the miter surface between the two frame profiles 1.

The assembly of the miter joint is quite easy to carry out. Another advantage is that the frame profiles 1 do not have to be milled or drilled and that the cavities 2 ( 2 ) remain largely open to each other in adjacent frame profiles 1. As a result, if necessary, lines or cables can be easily routed in the frame profiles 1, also via frame corners, and heat shields and insulating material can also be attached to the corner area of frame profiles 1 in the cavities 2. For the attachment of heat shields and insulating material, it is particularly advantageous that - as drawn - pull angle 46 and support angle 45 extend only between the two profile walls 9 and not up to the side surfaces 4 of the frame profiles.

In 10 two versions of cover profiles 51, 52 for the profile cavity 2 of frame profiles 1 that can be used according to the invention are outlined, which are to be clamped in each case on the two protruding profile walls 5 and bridge the distance between the profile walls 5, so that they thus cover the profile cavity 2.

The cover profile 51 is a simple plastic extrusion profile or metal profile. It mainly has an optical function.

The cover profile 52, on the other hand, has a fire protection function in addition to the optical function and is made up of several different parts for this purpose: the support profile 53 is a plastic extrusion profile; it serves as a support for the other parts and is clamped to the profile walls 5 above. It has a profile cavity which is covered by a very thin profile wall 54 on the fold side. A fire protection swelling agent 55 is arranged in the profile cavity. In the event of a fire, the profile wall 54 melts away and the fire protection swelling agent 55 swells, absorbing energy and, as intended, closing the gap between the two frame profiles 1 . The boundary wall of the profile cavity in the support profile 53 facing away from the fold side is covered by a metal strip 56 . Unlike the support profile 53, this retains its stability even in the event of a fire and prevents the fire retardant 55 from spilling out in the wrong direction.

In the right part of the profile cavities 2 of the frame profiles 1 of 10 two other forms of heat shields 60 are also outlined. These are like the heat shields 38 from 8 typically formed by sheet metal strips.

11 shows further built-in parts in the profile cavity 2 on a frame profile 1 to be used according to the invention. A cable duct profile 58 designed as a flat U-profile is clamped between two profile walls 9, which project from the base surface 3 of the frame profile 1 into the profile cavity 2 and are curved in profile towards one another like a hook. The raceway profile 58 is typically a plastic extrusion profile. It rests on the frame profile 1 on the profile walls 9 with its free leg ends designed as locking tips, which are bent towards each other between the profile walls 9 compared to their relaxed position. The cable duct profile 58 covers cables 59 opposite the outer part of the profile cavity 2 of the frame profile 1.

In 12 Construction and installation situation for a clamping profile 107 in a frame profile 1 are shown, with the clamping profile 107 acting as a double heat shield. The clamping profile 107 is typically made of sheet steel and has an approximately U-shaped cross section, with the legs being slightly slanted apart and with the free ends of the legs spanning a slightly larger distance in the elastically relaxed state than those walls of the frame profile 1 on which these leg ends are spaced apart should be present when installed. Thus, when installed, the free ends of the legs of the clamping profile 107 press against the frame profile 1 under elastic pretension and thus hold the clamping profile 107 in the frame profile 1 with a non-positive fit and without play. The base of the clamping profile 107 runs close to the base of the frame profile 1, but is ideally - as outlined - slightly curved away from this. Analogous to the breakthroughs 8 of the frame profile 1 of 2 the base of the clamping profile 107 have a grid of openings to make heat conduction more difficult.

The clamping profile 107, which represents a double heat shield, can be installed particularly quickly; however, it can only be installed in longitudinal areas where no clamping part according to the invention is to be attached.

13 shows, on a frame profile 1 used according to the invention as a frame part of a door frame, the installation of a smoke detector 66, which only has to function when the door leaf is open. The central part of the smoke detector 66 is located in the profile cavity 2 of the frame profile 1 and is connected to a forend plate 68 and fastened thereto, as already described above with reference to other fittings, by means of a clamping part 11 according to the invention to protruding profile walls 5 of the frame profile 1. In the example shown, the smoke detector 66 is connected via a cable to an LED display 67, which is inserted into a hole in a side surface of the frame profile 1 in such a way that it is visible from the outside. So that smoke can get to the smoke detector 66 at all, the forend plate 68 has slits 69 and the seal, which is located between the frame profile 1 and the building wall to which the frame profile 1 is attached, is locally pierced by channels, which lead the two spaces separated by the frame profile 1 through an opening in the base surface 3 of the frame profile 1 into the profile cavity 2 of the frame profile 1 . in the in 13 Example shown is to provide seal and. Channels a flat hollow body 70, which has at least three openings, arranged between the frame profile 1 and the adjacent building wall. In the hollow body 70 there is a fire protection swelling agent 71 which swells up in the event of a fire due to the effect of heat and closes the channels of the hollow body 79 .

14 shows a frame profile 39 on a door leaf, which has two cover layers 40 which are typically made of wood and cover the frame profile 39 laterally. In the space between the two cover layers that is not occupied by frame profiles 39, there is a plate-shaped core 18, which consists, for example, of a heat-insulating material. In the advantageous embodiment shown, a side wall of the frame profile 39 is extended by a profile wall 81 beyond the mere framing of the profile cavity towards the fold surface and the second side wall of the square profile 39 is extended by a profile wall 83 beyond the mere framing of the profile cavity away from the fold surface. The cover layers 40 can be screwed to the frame profile 39 by means of screws 41 through the profile walls 81, 83, with the screws 41 penetrating into the cover layers 40 from the side facing away from the visible side, which of course is optically advantageous.

15 shows a frame profile 43 on a door leaf 42, which is essentially designed as a strong wooden panel, in the end faces of which a groove is milled into which a frame profile 43 is inserted for each end face. In this case, the frame profile 43 and the wooden panel can be screwed together by screws 41 which run from the profile cavity of the frame profile 43 through the base surface of the frame profile 43 .

16 shows an advantageous way of attaching an adjustable block to a movable, flat encryption element, for example a glass door, which comprises frame profiles 90 and a core (glass pane 32). Using the example of a revolving door, the adjustable blocking is optimally attached to the end of the upper face of the core that is remote from the axis of rotation of the door. The blocking consists of two acute-angled cables 91, 92 and a screw 93, the two wedges 91, 92 being arranged in the corner area of two frame profiles 90 in the gap between the base surface of the horizontal frame profile 90 and the face of the core (glass pane 32). The wedges 91, 92 rest with one of their two wedge surfaces against each other. One wedge 91 rests with the second wedge surface on the base surface of the frame profile 90 and the second wedge 92 on the end face of the core. The screw 93 passes through a hole in the base of the vertical frame profile 90 and into a nut hole on a wedge 91. Tightening the screw 93 pulls the wedge 91 towards the vertical frame profile 90, which increases the thickness given by the sum of the thicknesses of both wedges 91 , 92 formed total thickness of the blocking increases and thus the horizontal frame profile 90 is raised relative to the core. To change the thickness of the blocking, you only need to cover the profile cavity of the upper part when the door is open of the vertical frame profile 90 on the lock side and turn the head of the screw 93 in the profile cavity with a screwdriver. In contrast to conventional constructions of transfigurations, there is no need to remove a glazing bead to change the thickness of the blocking, and the associated handling of the sealing material to be arranged between the glazing bead and the glass pane is also eliminated.

17 shows in a profile view, for example on a glass door leaf, the use of a frame profile 72 which is used according to the invention and is formed from two separate profile parts 73, 76. The two profile parts 73, 76 essentially form the side surfaces of the profile 72, which enclose the profile cavity 74 between them.

On the side facing the rebate surface, the profile cavity 74 is as in the example according to FIG 1 bridged by a clamping part 11, a forend plate 17 and these two mutually pulling screw 16 by between the clamping part 11 and forend plate 17 two profile walls projecting over the profile cavity 74 of the frame profile 72 are clamped.

Instead of the base area of the frame profile that is otherwise present, a row of several screw connections 21 is arranged on the side of the profile cavity 74 facing away from the rebate area, which, as already explained with reference to FIG 1 They each have a clamping part 22, a counter-plate 23 and a screw 24, with the screw 24 pulling the clamping part 22 and the counter-plate 23, in which there is a nut thread, towards one another and edge areas of the clamping part 22 and counter-plate 23 each protruding Profile wall 75 of a partial profile 73, 76 pinch between them. For reasons of the assembly sequence, the screw connection 21 is aligned in such a way that the head of the required screw 24 is arranged in the profile cavity 74 and not as in the screw connection according to FIG 1 outside the profile cavity.

The construction with two locally connected partial profiles 73, 76 to form a frame profile 72 offers material savings and better modularity than designs with a monolithic frame profile and it saves separate glazing bead profiles. However, the construction also leads to compromises in terms of strength and workload during assembly. The construction method can be particularly worthwhile when doors or windows are required for which special frame thicknesses that only occur very rarely are required.

18 shows a frame profile that can be used according to the invention, which is formed as a combination of three partial profiles 77, 80, 82 arranged parallel to one another. The middle profile 77 is essentially a U-profile in which the free leg ends are curved inwards, i.e. over the profile cavity 78 and in the manner already described by screwing, which are each formed from a clamping part 84, a forend plate 85 and a screw 86 , are connected to each other. However, the side surfaces of the middle profile 77 each also have two wall areas projecting outwards. The side surfaces of the central profile 77 are connected to these outwardly projecting wall areas by means of further screw connections according to the invention, each of which is formed from a clamping part 88, a forend plate 87 and a screw 89, with a further partial profile 80, 82 in each case.

This design is particularly advantageous when a high level of modularity is required to adapt to different requirements of insulation and/or fire protection classes.

19 shows a sectional view of frame profiles 108, 109 which can be used according to the invention and which are each formed from three partial profiles for the purpose of thermal insulation. As usual, the lateral partial profiles are made of metal, in the example shown typically made of rolled sheet steel. The middle partial profiles 110, 111 are best made of a material that conducts heat much less well than metal, such as in particular plastic or a bandage made of non-metallic fibers and a plastic. The individual partial profiles are clamped together, ie they interlock with individual profile wall surfaces in such a way that a wall area of a partial profile is encompassed by wall areas of the adjacent partial profile aligned parallel thereto. At the connection area, the partial profiles are preferably in contact with one another with elastic compressive pretension. The partial profile (110, 111) made of the less strong and elastically softer material is preferably that of which a wall area is surrounded by wall areas of the adjacent profile. In the event that the metal, side partial profiles are formed by sheet metal roll forming, the central, heat-insulating partial profile (110, 111) can be connected during the roll forming. If the metal, side partial profiles are extruded aluminum profiles, the connection is made by subsequent pressing in of the middle partial profile.

20 Using the example of a door leaf 42 made of solid wood, in which a frame profile 94 is used, shows a very advantageous way of installing a fitting 19 formed by a lock case 19 and the associated handle rosette 101.

The lock case 19 is arranged in the frame profile 94 and it as already on hand 1 described by means of a forend plate, a clamping part and a screw attached according to the invention. In addition to the lock case 19, a holding part 96 is arranged in the frame profile 94. The holding part 96 is typically made of sheet steel; it has approximately the shape of a U-profile and as such it is arranged parallel to the frame profile 94 in this, whereby the outwardly bent free end areas of its profile legs are bent together slightly in the elastic area compared to their relaxed position, so that they are at the Inside of the side surfaces of the frame profile 94 under pressure and thus hold the holding part 96 non-positively but not positively in the frame profile 94. The lock case 19 protrudes through a recess 97 in the base surface of the holding part 96 . From the lock case 19, the handle axis 100 (usually a square profile) protrudes normal to the plane of the door leaf 42 through an opening 99 through a leg of the holding part 96, as well as through an opening 95 through a side wall of the frame profile 94 and through an opening 61 on the door leaf 42 through. The opening 95 through the frame profile 94 and the opening 61 through the door leaf 42 are dimensioned significantly wider than the cross-sectional dimensions of the handle axis 100. The handle axis 100 also runs through a through-hole in the handle rosette 101, although the cross-sectional dimensions of this through-hole are dimensioned so narrowly that the handle axis 100 is held free of play against translational movement normal to its longitudinal direction. Screws 102 protrude from the handle rosette 101 at a distance from the handle axis 100 through wide screw through-holes in the door leaf 42 and in the frame profile 94 to threaded holes 98 in a deep-drawn area on the holding part 96.

When assembling the arrangement, the holding part 96 is pushed into the frame profile 94 first. Then the lock case 19 according to the invention as on hand 1 described by means of a forend plate, clamping part and connecting screw on the frame profile 94 in such a way that it extends into the space between the legs of the holding part 96 and protrudes through its recess 97 and that the handle axis 100 passes through the associated recesses on the door leaf, frame profile and holding part can be inserted through into the bearing mount provided for this purpose on the lock case 19. When the handle shaft 100 is inserted and the rosette 101 is pushed onto it, the screws 102 are inserted through the screw holes in the rosette 101 and through the screw holes, which are very large for this purpose, on the door leaf 42 and on the frame profile 94 and into the associated threaded holes 98 on the holding part 96 and only carefully tightened and the handle rosette 101 is fixed on the door leaf in precisely that position in which the handle axis runs optimally, without bending and forcing, through the associated through-hole on the handle rosette. When the screws 102 are tightened, the retaining part 96, which can still be moved in the frame profile 94, slides either by itself or by being moved from the open side of the frame profile 94 using a tool, almost exactly to the optimum position in which the screws 102 are aligned normal to the plane of the door leaf when the handle rosette 101 is optimally positioned. If the screws 102 are now firmly tightened, the push button rosette 101 is fixed in exactly the right position without play for years in order to guide the handle axis 100 in such a way that it is aligned with the associated axis of the receptacle in the lock case 19 without bending or constraint.

(In the case of state-of-the-art designs, the position of the retaining screws for the handle rosette in relation to the door leaf is precisely specified, which means that tolerances in relation to the position of the lock case in relation to the door leaf inevitably lead to an unsuitable bearing of the handle axis, which subsequently leads to poorly pivoting handles and the destruction of swivel mechanisms caused.)

The frame profiles according to the invention shown and explained are best made of steel or aluminum, the most important manufacturing processes being roll forming and extrusion. However, for applications where there are rather lower strength requirements, it can also be advantageous to design the frame profiles as plastic extrusion profiles.
