Description

The invention relates to a device which comprises a frame and a flat closure element and serves for closing a building opening, wherein the flat closure element and / or the frame rigidly attached to the edge of the building opening has a frame profile, which is open to the rebate surface cavity on three sides includes.

The word "folding surface" in this document means the surfaces at least approximately normal to the plane of the flat closure element, to which flat closure elements face each other when the wall opening is closed or face planar closure element and frame.

A "flat closure element" in the sense of this document is typically a window sash or a door regardless of the type of leadership of his mobility so for example regardless of whether it is in the case of a door to a hinged 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 as so-called "all-glass wing" trained wings of swing doors or windows. In this case, two parallel to each other, at a distance from each other arranged glass sheets are glued together with the interposition of a running along the edge of both disks spacer profile. Furthermore, the free-lying side of the spacer profile is provided with a so-called fitting groove.

A so-called "fitting groove" (a standardized version of which is sometimes called "Euronut" in professional circles) is known above all for window frame profiles. It is a shallow groove which may have an opening area narrowed by projections from the groove flanks. The fitting groove serves to guide push rods on turn / tilt and turn windows and positioning of fittings or holes and cutouts for it to facilitate in the normal to the window plane directions. It is generally not used to make drilling and milling superfluous.

The DE 198 60 217 A1 shows a hinged door to be used as a front door in which the door consists of a rectangular plate-shaped core made of an insulating material, for example a metallic profile frame and two cover layers, wherein the profiles of the profile frame have a rabbet surface open groove. The profile frame runs around the end faces of the core around it. The top surfaces are on both sides of the core and profile frame parallel to their common plane and are bonded to both the core and the profile frame so that a stable sandwich is formed. At the opening surface of the rabbet surface open groove of the profile frame jumps out of each of the two groove flanks in each case a short, normal to the groove flanks aligned profile wall. According to the invention, hinge fitting parts or a lock can be fastened in said groove. The projecting from the groove sides profile walls are probably used as a mounting aid. On the underside of the door leaf, the groove is covered against the entry of dirt with a cover strip. Probably to achieve high stability of the proposed for use as a front door swing door, the profiles of the profile frame are sized very large and covered by the outer layers of the door leaf and glued to it. However, the construction is not sufficiently stable for use as fire doors that are automatically closed and opened.

Also the GB 2478754 A shows a hinged door, wherein the door consists of a rectangular plate-shaped core and a metal profile frame and two cover layers, wherein the profiles of the profile frame have a rabbet surface open groove. The profile frame extends around the end faces of the core around it. The deck surfaces run on both sides of the core and the profile frame parallel to their common plane and are connected to both the core and the profile frame to form a sandwich. At the opening surface of the rabbet surface open groove of the profiles of the profile frame jumps out of each of the two groove flanks each have a short, normal to the groove flanks aligned profile wall. For the purpose of mounting fittings on a profile a Stulpblech and a clamping part are attached to the projecting profile walls by these bridge the distance between the projecting profile walls, from opposite sides to the projecting Abut profile walls, and are pulled together by one or more screws with the interposition of the projecting profile walls.

The cuff plate is connected to the fitting, typically by screws. The contact surfaces of the Stulpblechs and the clamping part with the projecting profile walls of the profile are substantially only parallel to the planes of the face plate and clamping part. This keeps the connection between these parts with the profile only in the normal direction to the plane of these parts form fit. In all other directions, the connection holds only non-positively. At least for doors that are subject to high mechanical stress and for which the reliable function is relevant to safety, that is not enough.

High mechanical stresses on a hinged door occur not only due to their weight or if this is to withstand a burglary. An extreme case of occurrence and difficulty of mechanical stresses relates to swing doors which, due to safety requirements, must have an automatic closing and opening mechanism, as is typical for fire doors, especially in sweiflügeligen fire doors, the case. The greatest mechanical stress in such doors is that they must perform five hundred to one million automatically triggered opening and closing cycles during standard tests without interruption without even a single part or a single connection may fail so much that the function no longer safe given is. (The exact number of test cycles depends on the country specifics of the standards). Two-leaf swing doors as fire doors do not only have a closing sequence control which must cause the overturning wing (active leaf) is always safely closed after the underpinning wing (inactive leaf), but also an opening sequence control which must cause when the inactive leaf is opened, forcibly also the active leaf is opened at least up to that minimum opening angle, from which it is ensured that the closing sequence control works safely. In particular, in the test of the opening sequence control, in which the inactive leaf is opened by an external actuator and consequently automatically opened by a built into the door transmission mechanism of the active leaf at least up to said minimum opening angle, occur due to in some opening angle ranges unfavorable (dead center) leverage on individual Fitting briefly on extremely large forces.

Exactly with such doors many fittings are to be mounted in and on the frame and on the wings, so that a quick, easy and flexibly adjustable mountability of fittings in profile without the need for separate holes or cutouts would be economically very desirable. Due to the difficulties arising from the described mechanical requirements, but so far was not satisfactory possible.

• 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 task underlying the invention is to propose a construction method for a lockable building opening designed as a window, door or gate, wherein the movable closure elements and / or the frame rigidly attached to the edge of the building opening have a frame profile whose cross-sectional area is one to the rebate surface open cavity on three sides. Compared with known construction methods in which such a cavity occurs, the design to be created - with good economy and without having to accept optical disadvantages - allow the following combination of improvements:

• The cavity open towards the seam 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 on the frame profile for this purpose.
• The design should allow such high mechanical strength that accordingly also swing doors with high mechanical stress such as fire doors in particular with automatic opening and closing sequence control can be built accordingly and indeed without it being necessary to form frame profiles and top surfaces of a door leaf a sandwich ,

An important secondary task is that the work required for the production of the movable closure elements and the frames should be low.

For solving the tasks of a construction is assumed, in which a frame profile bounded to the rebate surface cavity bounded by three in cross-section approximately U-shaped boundary surfaces, which protrudes from the two side Begrensungsflächen each profile wall which the width of the cavity in cross-sectional view locally constricted, wherein on the projecting profile walls fitting parts with the aid of a clamping part can be fixed by the projecting profile walls are clamped in between and by clamping part and fitting to bridge the cavity between the two projecting profile walls.

As an improvement according to the invention it is proposed to form the connection between the clamping part and projecting profile walls in such a way that they block relative movement between the projecting profile walls away from one another and also towards each other. To produce this positive locking the Beruhrungsgeometrie between projecting profile walls and clamping part is designed so that the clamping part abuts the two projecting profile walls respectively on both flanks of a groove formed on each of the projecting profile walls and the opening surface parallel to the connecting surface between the two projecting Profile walls lies, and wherein a fitting in the groove portion of the clamping part at the contact surface with the groove has a toothing. In a particularly preferred embodiment, the said groove on the projecting profile walls is designed so that the distance between their flanks at that area at which the clamping part abuts decreases with increasing groove depth. This is particularly simple and reliable play-free positive connection between the frame profile and the clamping part achievable.

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

The importance of the invention is mainly due to many applications in which the construction of the invention considerable advantages Therefore, in addition to the basic principle of the invention, some such exemplary applications are outlined and described below.

Apart from individual possibly shown fastenings of fittings, the devices fall according to the drawings FIGS. 14 to 16 and Fig. 20 not covered by the present claims. These drawings and the accompanying text of the description serve only to facilitate the understanding of the invention by also treating devices which, although not covered by the present claims per se, but can be combined particularly advantageously with a device according to the present claims.

Fig. 1 shows the zugawandten each other zugugandten area of two pivot door leaves, which apart from the fittings of a glass plate 32 and a comprehensive frame of Bahmen profiles 1 and glazing beads 31 are formed.

The frame profile 1 is typically formed by roll forming from sheet steel. Details of the frame profile 1 are partially in Fig. 2 better to recognize than in Fig. 1 , It has a substantially U-cross-sectional shape, and as such, in a cross-sectional view encloses the profile cavity 2 on three sides, wherein the open side of the profile cavity is aligned in each case to the rebate surface, in the case of Fig. 1 So the other frame profile 1 out.

In the in Fig. 2 shown. By way of example, the glass pane 32 of each pivoting door leaf is held against the frame profiles 1 by being clamped along its edges between two glazing beads 31 with the interposition of an elastic sealing profile 33. The glazing beads 31 are also profiles which are typically formed by roll forming and seam welding of a steel sheet strip. The glazing beads 31 respectively lie on the outside of the base surface 3 (FIG. Fig. 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. Thus, a secure and detachable connection is formed without fasteners of are visible on the outside. For reasons of space and reasons of comfortable 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 height above the base surface 3 of the frame profile 1 of each of the two lateral surfaces 4 (FIG. Fig. 2 ) of the frame profile 1 to a profile wall 5 on the cavity 2 to forth so that the width of the cavity 2 is narrowed in the height range of the two profile walls 5 with respect to the width in adjacent height ranges,

Fig. 1 further shows the inventive assembly of a fitting 19 in a frame section 1, in this example, the fitting 19 is a lock case. The fitting 19 is arranged substantially in the cavity 2. It is rigidly connected to a cuff plate 17, which rests against the side facing away from the base surface 3 of the frame profile 1 side of the profile walls 5, while the cavity 2 covers.

At the base surface 3 of the frame profile 1 applied side of the profile walls 5 is a clamping member 11 on the profile walls 5 at. A screw 16 rests with its head on the outer side of the cuff 17. The threaded bolt of the screw 16 extends through a bore in the cuff plate 17 and is provided with a threaded bore in the central part 12 (FIG. Fig. 3 ) of the clamping member 11 in threaded engagement. By the force exerted by the screw 16 tensile force plate 17 and clamping member 11 are pressed toward each other. Against movement towards each other are Strulpblech 17 and clamping member 11 supported by dis profile walls 5 at which they rest, so that clamping member 11 and cuff 17 from opposite sides a. Pressing force on each projection 10 (FIG. Fig. 2 ) exert the profile walls 5 in sum is the same size as the tensile force of the screw. 3

Of inventive importance, that the contact surfaces between the clamping part 11 and profile walls 5 of the frame profile 1 is not just normal to the screw 16 flat surfaces, but that the clamping member 11 with its two opposite its central part 12 to the profile walls 5 projecting edge portions 13th each on both flanks of each a groove 6 ( Fig. 2 ), whose groove base is located on a profile wall 5 and the opening surface of which is aligned with the base surface 3 of the frame profile 1 and whose width continuously increases at the contact area with the clamping member 11 from the groove bottom to the opening surface.

By this construction it is achieved that the clamping member 11 is a safe backlash-free and positive blockage against relative movements of the two side surfaces 4 of the frame profile 1 each other au and away from each other. This effect is further enhanced by the fact that the faceplate 17 is held positively against lateral displacement of the frame profile 1 by a wall portion of a profile wall 5 is applied frontally on both side end walls of the cuff 17, since the cuff plate 17 on the profile walls 5 respectively in a corner region 7 abuts, at which a plane lying parallel to the base surface 3 of the frame profile 1 surface in a applied by this, lying about normal surface.

The illustrated frame profile 1 would be relatively easily deformable by itself so that its two side surfaces 4 are bent toward or away from each other. By the described arrangement of clamping parts 11, this softness is corrected, so that the frame profile 1 in those longitudinal areas where clamping parts 11 are arranged is similar to stiff and firm as a closed hollow profile.

The invention thus makes it possible to provide even for doors with extremely high mechanical requirements light and slim frame profiles 1, which have a rabbet surface open cavity 2 in which fittings 19 can be conveniently mounted and which on the other hand, single-walled, ie without hollow chamber, executed so that they are easy to manufacture and, if necessary, easy to work with. One needs only at those longitudinal regions of the frame profiles 1 at which high mechanical loads are to be expected to mount clamping parts 11 as shown. Optionally, as a complementary part to a clamping member 11, a cuff plate 17 are used, which is not connected to a fitting 19, but simply a plate which is pressed by the clamping part 11 opposite side according to the force of screws 16 on the profile walls 5.

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

As in Fig. 3 recognizable, the projecting edge portions 13 of the clamping member 11 with which they are intended in grooves 6 of the frame profile 1 to equip such a toothing 14 that when properly arranged the clamping member 11 on a frame profile 1, at the contact surface of a peripheral region 13 with boundary surfaces of Groove 6 in the profile direction of the frame profile 1 elevations and depressions alternate. By the force with which the teeth 14 of the clamping member 11 is pressed into the groove 6, the tips of the teeth are pressed into the material of the frame profile 1, whereby the clamping member 11 is held formschlussig against the frame profile 1 against slipping in the profile direction.

Fig. 4 shows a construction of a clamping member 103, whose intended to be brought into engagement with a frame profile edge regions are rounded at diagonally opposite end portions. The clamping part 103 is more comfortable to mount than the clamping part 11, since needs to be swiveled to the intended mounting in the profile cavity of the relevant frame profile only about the axis of its threaded bore and not a normal axis lying. This is especially important if in the profile cavity more items are already seconded, so that already little space is available.

Fig. 5 shows in an oblique view an exemplary corner angle 104 for connecting two inventive frame profiles over a miter surface. The two legs of the corner angle 104 are like the cuff plate 17 according to Fig. 1 to create clamped on the profile walls of the Rähmenprofile and press by means of clamping member 11, 103 and screw 16 to the respective profile walls. In contrast to the cuff plate 17 of Fig. 1 The legs of the corner angle 104 are only on the adjacent to the miter areas longitudinal areas of the respective profile walls. The corner joint is easy to assemble and very stable.

At the in Fig. 6 sketched installation according to the invention of a: fitting 19 in a frame section 1 is connected to the fitting 19 Stulpblech 106 is not directly on the frame profile 1, but using a Isolationszwichenlage 105 of a heat-insulating, preferably heat-resistant, material.

In Fig. 7 is an example outlines how an inventively executed frame profile 1 can be used as a slide for a sliding block 62 of a slide rail door closer.
According to the known operating principle of sliding rail door closers along the upper door frame part (formed by a frame section 1) linearly slidably mounted sliding block 62 is connected via a pivotable arm 64 with a rotary drive 65 which is held stationary at the top of the swing wing relative to this and which on the pivotable arm 64 exerts a torque about an axis parallel to the pivot axis of the door leaf. (The reverse construction is also possible, according to which a along the upper edge of the door linearly slidably mounted sliding block is connected via a pivotable arm with a fixed at the upper door frame part rotationally fixed drive.) By a construction as in Fig. 7 sketched, an inventively designed frame profile 1 can take over the function of otherwise executed as a separate part slide. The sliding block 62 extends to between the projecting from the side surfaces 4 of the frame profile 1 profile walls 5 ( Fig. 2 ) and it is provided on each of its two side surfaces with a groove in which in each case a projection 10 projects a profile wall 5, so that the grooves on Gleitstein 62 act as Gleitführungsnuten to which the projections 10 are the complementary parts.

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

In consistent application of the present inventive concept is according to Fig. 7 Also, the rotary drive 65 of the slide rail door closer, on which the second end of the pivot arm 64 is held, held in the cavity of another frame profile 29 according to the invention. The attachment of the rotary drive 65 in the frame section 29 is the same as that of the fittings 19 of. Fig. 1 with the help of clamping members 11, one connected to the rotary drive 65 Stülpblech 17 and screws which Stulpblech 17 and clamping members 11 press against each other so that they pinch a part of the side walls of the frame profile 29 projecting profile walls between them. The frame profile 29 forms the example according to Fig. 7 the upper frame part of a revolving door wing. In this way, an optically extremely inconspicuous construction of a Gleitschienentürschließers is realized. It is unnecessary to use a separate slide rail. Moreover, a very simple assembly is possible in addition to the very good adjustability with respect to the position of the rotary drive 65 along the associated frame profile 29 is given.

In Fig. 7 is also outlined a way how adjacent frame sections 29 of a door frame or a frame can be connected together. For this purpose, two so-called Eckklemmwinkel 25, 26 are provided. These Eckklemmwinkel 25, 26 each consist of two identical, with each other at an angle of 90 ° connected profile legs. The cross-sectional areas of the profile legs are dimensioned so that they can be inserted into the frame profile 29 to form a press fit in each case an undercut groove, so that they stuck there without play. In the in Fig. 7 Against movement away from this base surface, the Eckklemmwinkel 25, 26 are on the one hand by an upstanding from the base surface of the frame profile 29 profile wall 9 and on the other hand by those profile wall. 5 held on which also the clamping part 11 rests, which serves for the inventive fastening of fittings in the frame section 29.

The frame profile 29 according to Fig. 7 differs from the previously predominantly discussed frame profile 1 in that it has a profile wall 30 which protrudes from the side facing away from the cavity of the base surface and can take over the function of a glass bar, so that each frame section only a single separate glass bar 31 is required.

Fig. 8 shows - among others - the inventively executed compound of hinge parts on a swing door leaf and the associated stationary frame. Frame profiles 1 form the Turzarge. Frame profiles 29 (with integrally formed profile wall 30, which serves as a glazing bar) form the frame of the swing door wing formed as a glass wing. The journal 34 about which the pivot door wing is pivotable relative to the frame is located in front of the space enclosed by the frame profiles 1 space. From the journal 34 from one another arranged support arms protrude into the near Falzflache between pivot door leaf and frame and are there connected by screws 16, each with a cuff 36 and a clamping member 35 on the frame profile 1 and 29 respectively. Because of this. Case expected particularly high loads, the cuff plates 36 and the clamping members 35 each have two connecting screws 16 to each other and not just one like the Stulpbleche 17 and clamping parts 11 in the examples discussed above. Also in this case, the arrangement is visually inconspicuous, easy to install and along the longitudinal direction of the frame profiles 1, 29 detachably fastened at any position, without the need for any holes or cutouts.

Fig. 8 further shows how the frame profiles 1, 29 can be "upgraded" to have improved edge protection properties.

At the left side of the respective cavity of the frame profile 1, 29, a heat shield 38 is clamped. It has in this case the shape of a flat U-profile, wherein the free legs abut the respective side wall of the frame profile 1, 29 and thus the base of the flat U-profile is arranged at a respective distance to the respective side wall of the frame profile 1, 29 , Preferably, the free ends of the legs of the U-profile, which forms a heat shield 38, provided with a toothing, so that they are not in line contact with the frame profile 1, 29 but with a series of point contacts, since thus heat conduction between the two parts is reduced. The heat shields 38 are mainly used to prevent heat radiation from one side surface of the cavity 2 of the frame profile 1, 29 on the other side surface. It is particularly advantageous in the illustrated embodiment that the heat shields 38 can also subsequently be introduced and clamped into the frame profiles 1 from the open side of the cavity 2, ie, from the rebate surface.

At the respectively right side of the respective cavity of the frame - profile 1, 29 a fire protection body 37 is inserted in each case.

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. Unlike the heat shield 38, it not only stops heat radiation but also slows down heat conduction very much.

By different, different strong and different numbers of heat protection objects in the hollow chamber 2 of a frame profile 1, 29 are arranged, the frame profile 1, 29 easily to various fire protection classes such as F30, F60, F90, etc., modular adaptable. This results in economically very valuable advantages in terms of manufacturing and assembly logistics.

For the jamming of fire protection body 37 and heat shield 38 against movement normal to the frame plane of the frame profiles 1, 29 frame, fire protection body 37 and heat shield 38 are each clamped between a side surface of the frame profile 1, 29 and other profile walls, one of these further profile walls of the inside surface of the frame profile protrudes inward; on the frame profile 1, this is the profile wall. 9

In the frame profiles 1, 29 directly, heat conduction can only take place through the base surface 3 (FIG. Fig. 2 ) from a side surface 4 ( Fig. 2 ) on the other. Side surface 4 done. You can brake this heat very strong by the base 3 as in Fig. 2 clearly recognizable, with a grid of openings 8 provides, so that the cross-sectional area for heat transfer by heat conduction in the material of the frame profile 1 is reduced and the transmission path is extended. It is particularly advantageous if the apertures 8 as illustrated are slots whose longitudinal direction is parallel to the profile direction and when several rows of slots to each other by a half pitch to each other are longitudinally offset side by side.

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

Fig. 9 shows in two views an advantageous construction to connect two usable according to the invention frame profiles 1 miter to form a frame for a door surface or a window surface. This is done using a corner clamping fitting 44, which consists of four different components:

The support bracket 45 consists of two flat rectangular sheet metal pieces, which are connected to each other along a short end face and are at a right angle to each other. The support bracket 45 is located in the cavity of the mitred adjoining frame sections 1 at the base surfaces 3 at.

On the support bracket 45 is another angle, the so-called draft angle 46 on the outside. It also consists essentially of two flat Blechrechtecken which are connected together along their short end faces and each other at a right angle. The lateral end faces of the drawbar 46 are provided with a toothing 47, the tips of each bear against a profile wall 9 of a frame profile 1.

A screw 50 extends through a nut threaded hole in the pulling angle 46 therethrough. Said nut threaded bore extends through the traction angle 46 and it lies diagonally to the two legs. The screw 50 presses with its respect to the traction angle 46 inner end face to the boundary region between the two angle legs of the inner support bracket 45 at. Upon further screwing on the support bracket 45, it causes the pull angle 46 to be pulled approximately diagonally away from the support bracket 45.

Spreader pin 49 are rigidly connected to the legs of the support bracket 45. They have the shape of a circular symmetric mushroom and protrude from the legs of Stütswinkels 45 in the raised angle range between these legs and each extending through a leg extending in the elongated opening 48 on each adjacent leg of the drawbar 46 through. The width of the opening 48 decreases with increasing distance to the connecting surface between the two legs of the drawbar 4, it is also narrower than the diameter of the expansion pin 49 in their through the opening 48 extending longitudinal region.

By screwing the screw 50 on the support bracket 45 to, the legs of the drawbar 46 are moved to the support bracket 45 to the connecting line between the legs out. This results in longitudinal regions of the opening 48, at which the width of the opening at non-deformed draft angle 46 is less than the diameter of the extending through the opening longitudinal part of the expansion pin 49, on expansion pin 49. This causes the both sides of the opening 48 of the drawbar 46 located Parts of the drawbar 46 are spread apart and the teeth 47 are pressed firmly against the profile walls 9 of the frame profiles 1 and thus the Rahmenpröfile 1 are moved with the drawbar 46 relative to the support bracket 45 on the miter between the two frame profiles 1 out.

The assembly of the miter joint is so easy to carry out. It is also advantageous that the frame profiles 1 need not be milled or drilled and that the cavities 2 (FIG. Fig. 2 ) in adjacent frame profiles 1 remain largely open to each other. As a result, if necessary, cables or cables can be easily performed in the frame sections 1 and frame corners and it can also be attached to the corner of frame profiles 1 heat shields and insulating material in the cavities 2, For the attachment of heat shields and insulating material, it is particularly advantageous that - as drawn - drawbar 46 and support bracket 45 only between the two Profile walls 9 extend and not down to the side surfaces 4 of the frame profiles.

In Fig. 10 are two versions of cover profiles 51, 52 outlined for profile hollow 2 of the present invention applicable frame profiles 1, which are each clamped to both projecting profile walls 5 and bridge the distance between the profile walls 5, so that they cover the profile cavity 2.

The cover 51 is a simple Kunstoff extrusion profile barren metal profile. It has, above all, optical function.

In contrast, the cover profile 52, in addition to the optical function, also has a fire protection function and is constructed from several different parts: The support profile 53 is a plastic extrusion profile; it serves as a support for the other parts and is clamped to the projecting profile walls 5. It has a profile cavity, which is covered on the fold side by a very thin profile wall 54. In the profile cavity, a fire protection source 55 is arranged. In the event of fire, the profile wall 54 melts away and the fire protection source 55 swells up, absorbing energy and closing the gap between the two frame profiles 1 as intended. The facing away from the fold side boundary wall of the profile cavity in the support section 53 is covered by a metal strip 56. This content - unlike the support profile 53 - even in case of fire, its stability and prevents the fire retardant 55 swells in the wrong direction.

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

Fig. 11 shows on a according to the invention to be used frame profile 1 more built-in parts in the profile cavity 2. Side are sketched two further versions of trapped in the profile cavity 2, heat shields 57 out of sheet metal. Between two profile walls 9, which project from the base surface 3 of the frame profile 1 in the profile cavity 2 and hook-shaped in profile are curved to each other, designed as a flat U-shaped profile cable channel 58 is clamped. The cable channel profile 58 is typically a plastic extrusion profile. It rests on the frame profile 1 on the profile walls 9 with its designed as latching peaks free leg ends, which are slightly bent towards each other between the profile walls 9 with respect to their relaxed position. The cable channel profile 58 covers cable 59 from the outer part of the profile cavity 2 of the frame profile 1 from.

In Fig. 12 are shown construction and installation situation for a clamping profile 107 in a frame profile 1, wherein the clamping profile 107 acts as a double heat shield. The clamping profile 107 is typically made of sheet steel and has approximately U-cross-sectional shape, wherein the legs are slightly obliquely apart and wherein elastically relaxed state, the free ends of the legs span a little greater distance than those walls of the frame profile 1 are spaced from each other at which these leg ends should rest in the installed state. Thus, press the free ends of the legs of the clamping profile 107 in the installed state under elastic bias to the frame section 1 and thereby hold the clamping profile 107 frictionally backlash in the frame profile 1. The base of the clamping profile 107, runs close to the base of the frame profile 1, but is ideally - as outlined - something of this way arched. Analogous to the openings 8 of the frame profile 1 of Fig. 2 the base of the clamping profile 107 have a screening of openings to complicate heat conduction.

The clamping profile 107, which represents a double heat shield, can be installed very quickly; you can only do it though Install on longitudinal areas where no inventive clamping part is to be attached.

Fig. 13 shows, on a frame according to the invention used as a frame part of a frame of a door frame profile 1, the installation of a smoke detector 66, which only has to work when the door 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 cuff 68 and with this as described above on hand other fitting described by means of a clamping member 11 according to the invention on projecting profile walls 5 of the frame profile 1 attached. In the illustrated example, the smoke detector 66 is connected via a cable to an LED display 67, which is inserted into a bore in a side surface of the frame profile 1 so that it is visible from outside. So that smoke can reach the smoke detector 66 at all, the cuff plate 68 is pierced by Schilitze 69 and that seal which is located between the frame profile 1 and the building wall to which the frame profile 1 is located, is locally broken by channels, which of the two spaces separated by the frame profile 1 through an opening in the base surface 3 of the frame profile 1 in the profile cavity 2 of the frame profile 1 into it. In the in Fig. 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 adjacent building wall. In the hollow body 70, a Feuerschutsguellmittel 71 is arranged, which swells in ima case of a fire by the action of heat, and the channels of the hollow body 79 closes.

Fig. 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 area of space occupied by frame profiles 39 between the two cover layers is a plate-shaped Seconded core 18, which consists for example of a heat-insulating material. In the illustrated advantageous embodiment, a lateral wall of the frame profile 39 is extended by a profile wall 81 on the mere framing of the profile cavity to Falzflache out and extended the second lateral wall of the Rahatenprofils 39 by a profile wall 83 on the mere framing of the profile cavity of the rebate surface. Through the profile walls 81, 83 through the cover layers 40 can be screwed by means of screws 41 on the frame profile 39, wherein the screws 41 penetrate from the side facing away from the visible side into the cover layers 40, which of course is optically advantageous.

Fig. 15 shows a frame profile 43 on a door leaf 42, which is substantially formed as a strong wooden plate, in whose end faces a groove is milled into which each end face a frame profile 43 is inserted. In this case, Rahasenprofile 43 and wooden plate can be screwed together by screws 41 which extend from the profile cavity of the frame profile 43 through the base surface of the frame profile 43 therethrough.

Fig. 16 shows an advantageous method of attachment for an adjustable blockage on a movable planar Verschlüsselement, such as a glass door, which Rahmenprofile 90 and a core (glass pane 32) umfüffc. Using the example of a turntable, the adjustable blockage is optimally attached to the end of the upper end face of the core facing away from the axis of rotation of the door. The block consists of two acute-angled cables 91, 92 and a screw 93, wherein the two wedges 91, 92 are arranged at the corner region of two frame profiles 90 in the gap between the base surface of the horizontal frame profile 90 and the end face of the core (glass 32). The wedges 91, 92 abut each other with one of their two wedge surfaces. With the second wedge surface one wedge 91 abuts the base surface of the frame profile 90 and the second wedge 92 engages the end face of the core. The screw 93 extends through a hole in the base surface of the vertical frame profile 90 into a nut hole on a wedge 91. By tightening the screw 93, the wedge 91 is pulled towards the vertical frame profile 90, resulting in the sum of the thicknesses of both wedges 91st 92 increases the Gesaratdicke formed of the blockage and thus the horizontal frame profile 90 is raised relative to the core. For changing the thickness of the blocking, it is only necessary to remove the existing cover of the profile cavity of the upper part of the lock-side vertical frame profile 90 when the door is open and to turn it with a screwdriver on the head of the screw 93 located in the profile cavity. In contrast to conventional construction of Verklarungen need not be removed for changing the thickness of the blockage no glass strip and also the associated handling with the to be arranged between the glass strip and glass sealing material is eliminated.

Fig. 17 shows in profile view, for example, on a glass door wing, the use of an inventively applied frame profile 72 which is formed of two separate profile parts 73, 76. The two profile parts 73, 76 substantially form the side surfaces of the profile 72, which include the profile cavity 74 between them.

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

Instead of the otherwise existing base surface of the frame profile, a row of a plurality of screw connections 21 is arranged on the side of the profile cavity 74 facing away from the rebate surface. which as already on hand of Fig. 1 They each have a clamping part 22, a counter-plate 23 and a screw 24, wherein the screw 24, the clamping part 22 and the counter-plate 23 in which a nut thread is, pulls each other and edge portions of the clamping member 22 and counter-plate 23 each sine protruding Profile wall 75 of a sub-profile 73, 76 pinch between them. For reasons of Montgeablaufs the screw, 21 is aligned so that the head of the required screw 24 is arranged in the profile cavity 74 and not as in the screw according to Fig. 1 outside the profile cavity.

The design with two locally interconnected sub-profiles 73, 76 to form a frame profile 72 provides material savings and better modularity than versions with a monolithic frame profile and they save separate glazing bead profiles. However, the design also leads to compromises in terms of strength and workload during assembly. The construction can be particularly worthwhile when doors or windows are required, in which special, only very rarely occurring frame thicknesses are required.

Fig. 18 shows a erfindungagemäß usable frame profile, which is formed as a composite of three mutually parallel partial profiles 77, 80, 82. The middle profile 77 is essentially a U-profile in which the free leg ends are curved inwardly, ie over the profile cavity 78 and in the manner already described by Verschraubunen, which are each formed of a clamping member 84, a cuff plate 85 and a screw 86 , are interconnected. However, the side surfaces of the middle profile 77 also each have two outwardly projecting wall portions. With these outwardly projecting wall portions, the side surfaces of the central profile 77 by means of further inventive screwing, each consisting of a clamping part 88, a cuff plate 87 and a Screw 89 are formed, each connected to a further sub-profile 80, 82.

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

Fig. 19 shows in sectional view according to the invention usable frame profiles 108, 109 which are formed for the purpose of thermal insulation Each of three sub-profiles. As usual, the lateral part profiles are made of metal, in the example shown typically from rolled steel sheet. The middle part profiles 110, 111 consist of a metal which is significantly less heat-conductive than metal, in particular plastic or a dressing of non-metallic fibers and a plastic. The individual sub-profiles are jammed together, so engage each other with individual profile wall surfaces such that a wall region of a sub-profile is encompassed by wall regions of the adjacent sub-profile aligned parallel thereto. At the connection area, the partial profiles are in this case preferred and elastic pressure prestress against each other. Preferably, the partial profile (110, 111) of the less rigid and elastically softer material is that of which a wall portion is encompassed by wall portions of the adjacent profile. In the case that the metallic lateral partial profiles are formed by roll forming of sheet metal, the middle, heat-insulating partial profile (110, 111) can be connected already during roll forming. If the metallic, lateral sub-profiles are extruded aluminum profiles, the joining is carried out by subsequent pressing in of the middle sub-profile.

Fig. 20 shows the example of a door leaf 42 made of solid wood, in which a frame profile 94 is applied, a very advantageous method of installation for a formed by a lock case 19 fitting 19 and the associated handle rosette 101st

The lock case 19 is arranged in the frame profile 94 and it as already on hand of Fig. 1 described by means of a Stulpblechs, a clamping member and a screw according to the invention attached. 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 parallel to the frame profile 94 arranged in this, the outwardly bent free end portions of its profile legs are slightly bent in the elastic region with respect to their relaxed position, so they so on the inside of the side surfaces of the frame profile 94 bear under pressure and thus hold the holding part 96 non-positively but not positively in the frame section 94. The lock case 19 protrudes through a recess 97 in the base surface of the holding part 96 therethrough. From the lock case 19 protrudes the pusher axis 100 (usually a square profile) normal to the door leaf 42 through an opening 99 through a leg of the support member 96 therethrough, and 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 significantly further dimensioned than the cross-sectional dimensions of the pusher axis 100. The pusher axis 100 further passes through a through hole in the pusher rosette 101 therethrough, however, the cross-sectional dimensions of this through hole are so tight in that the pusher axis 100 therein is held free of play against translational movement normal to its longitudinal direction. From the pusher rosette 101 protrude at a distance from the pusher axis 100 screws 102 by far sized screw holes in the door panel 42 and the frame section 94 to threaded holes 98 at a deep-drawn portion of the holding part 96th

When mounting the arrangement, the holding part 96 is first inserted into the frame profile 94. Then, the lock case 19 according to the invention as if by hand Fig. 1 described by means Stulpblech, clamping member and connecting screw attached to the frame section 94 in such a way that it hisses in the space the legs of the holding part 96 extends through the recess 97 and protrudes through and that the pusher axis 100 through the associated recesses on the door leaf, frame section and holding part can be inserted into the designated bearing receptacle on the lock case 19. When inserted pusher axis 100 and attached to this pusher rosette 101, the screws 102 are inserted through the screw through holes in the handle rosette 101 and the very far sized screw through holes on the door panel 42 and the frame profile 94 into the corresponding threaded holes 98 on the holding part 96 and tightened carefully and thereby fixed the pusher 101 on the door leaf in exactly that position at which the pusher axis runs optimally, without bending and forcing through the associated through hole on the handle rosette. The slight movement of the screws 102 in the frame section 94 still slidable retaining member 96 slides when tightening the screws 102 either by itself or by moving it from the open side of the frame profile 94 ago by means of a tool fits, almost exactly in that optimum position, in which the screws 102 are aligned with optimally positioned handle rosette 101 normal to the door leaf level. Now, if the screws 102 are tightened vigorously, the printer rosette 101 is fixed exactly in the correct position for years to the pusher axis 100 to guide so that it is free of bending and forcing with the associated axis of the recording in the lock box 19.

(In construction according to the prior art, the position of the retaining screws for the handle rosette with respect to the door leaf is precisely specified, with which tolerances with respect to the position of the lock case relative to the door leaf forcibly lead to improper storage of the pusher axis which subsequently causing poorly swung pushers and destruction of pivoting mechanisms.)

The illustrated and explained frame profiles according to the invention are best made of steel or aluminum to finished with the most important manufacturing processes roll forming and extrusion are mentioned. For applications in which rather low strength requirements exist, it may also be advantageous to form the frame profiles as a plastic extrusion profile.
