Description

Concealed hinge for a door or window, and door or window equipped with it and method for mounting a wing in a fixed frame of a window or door.

The present invention relates to a concealed hinge for a door or window, more particularly for a door or window with a fixed frame and a wing which is suspended rotatably around a vertical axis in the fixed frame by means of one or more concealed hinges.

More particularly, the invention relates to a hinge for a door or window, the fixed frame and the wing of which contain a frame composed of hollow profiles composed of several profiles, in particular two outer shells, respectively on the outside and on the the inside of the door or window, and possibly an intermediate shell between them, the shells being interconnected by means of so-called insulating bars that form a thermal break between both sides of the door or window.

The frame profiles and the wing profiles are provided with

2;

a lip with which these profiles overlap when closed, of. the door or window and on which there is a seal for sealing between the frame profiles and the vent profiles

Concealed hinge means a hinge that is built into the space between the wing and the fixed frame, more specifically in the space with a closed door

BE2019 / 5485

The window is demarcated between the opposite walls of the frame and of the wing and the aforementioned lips, all this so that the hinge is not visible when the door or window is closed.

Known concealed hinges are made up of a frame part which is fixed on the frame and a wing part which is fixed on the wing, in particular at the above-mentioned opposite walls of the frame and of the wing, these two parts being hinged together by means of a

The known hinges require a relatively large installation space when closed, so that a large cavity must be milled in the profiles, which implies that

the profiles of s the door or window should be designed like this to be that there for the hinges must have sufficient space to be between the two, what entails that broad professional: Slates 2 0 needed, what goes against the trend. so narrow

use possible profiles.

For the installation of the hinge on the frame, holes are drilled in a known manner on the yard in the aforementioned wall of the frame, in which blind rivet nuts are fixed with an internal fire into which screws can be screwed for the fixing of the frame part of the hinge to the frame. .

This is a job that must be performed with due care by well-trained workers

BE2019 / 5485 technicians, which also implies that this takes a relatively long time.

DE 20.2010.004.163 also discloses a concealed hinge which is mounted in a space-saving manner on a wall of the frame by means of a frame part which contains the axis of the hinge and which is provided with lips with which the frame part on the outside of the frame said wall of the frame profile is fixed and of a part indented relative to the lips with the aforementioned shaft which fits in a recess in the aforementioned wall formed in a chamber of the frame profile, the frame profile with said lips against the wall of the frame profile is clamped by two separate 15 clamping blocks which are clamped in advance in the aforementioned chamber and which are tightened by means of screws through the lips towards the lips with clamping of the relevant wall between the lips of the frame part on the outside of the wall and the clamping blocks 20 on the inside of the wall.

A drawback is that the clamping blocks in this case are hidden under or behind the frame part when mounting the frame part on the frame profile in the room and can also slide during installation, which means the correct positioning of the frame. the frame part relative to the clamping blocks makes it difficult to install the screws.

From DE 299.22.023 another concealed hinge is known in which the frame part analogously against the outside of a wall along the inner circumference of the

BE2019 / 5485 frame is attached and clamped to it by means of a clamping plate which is fitted along the outer circumference of the frame profile and is provided with screw sleeves which extend transversely through the frame profile 5 to screw the frame part to the frame by screws to pull.

A disadvantage is that the clamping plate and the necessary passages and the screw sleeves must be fitted in the frame before the frame is mounted in a wall opening and that it is therefore no longer possible to move the hinge or to additionally install the hinge after placing the frame. install such a hinge later.

Another drawback is that such an attracting plate is located on the back of the profile where the glass and the glazing bars come when it concerns a door with a side light, not in other words with a window next to the door. Moreover, such a plate often forms a thermal bridge and is possible.

warp profile when tightening screws.

This hinge is also not provided with a height adjustment.

A concealed hinge is also known from the DE

25.01.257 with a frame part with clamping blocks that are mounted on the bottom of a recessed part of the frame profile and are fixed in it by means of screws that are screwed into a clamping bar in an underlying fitting groove.

A drawback is that the clamping bar must be pushed into the fitting groove before the frame is assembled and that the

BE2019 / 5485 clamping blocks must be unnecessarily long to ensure that the passageways for the screws in the clamping blocks are not obstructed by the presence of the shaft.

Another drawback is that for mounting such hinge profiles are required with a particularly large chamber size (distance from 6 to 4 in fig. 1) so that the center 7 does not invade. This makes it possible to. before mounting, insert the shaft into the frame part or the vent part or both. However, such profiles have a number of drawbacks. All contemporary profiles have a much smaller chamber size and the pivot point can never be placed in this space between them. frame and the wing profile, but somewhere in the tube. As a result, an opening must be milled in the profile wall and such a hinge cannot be mounted. Both the screws on the frame (through shaft) and those on the wing (through profile lip) cannot be reached in an assembled door. So only to be mounted by sliding in the shaft, which requires a disadvantageous profile with a particularly large chamber size.

It is on the side of the wing. known to provide a tap-hole connection between the wing and a hinge already pre-mounted on the frame, wherein a tap 25 with a widened head is to be hooked into a vertically extending slotted hole with the pre-mounted hinges which are in open position are rotated.

The slotted holes are provided with an entrance, whereby the wing is hooked by a horizontal movement of the wing towards the frame, after which the wing can be lowered in vertical direction to the tao

BE2019 / 5485 in this way to hook into the slotted hole, so that the wing can then be released in order to be able to screw the wing part of the hinge onto the wing.

A drawback of this is that there must be sufficient clearance in the vertical direction between the wing and the fixed frame in order to have sufficient movement space with the wing for hooking the wing, which implies that this requires wide frames. Especially the piecework of the ceiling and the door frame are the limiting factor here.

The mounting of the wing must be done with the wing and the frame in a vertical position, which makes it more difficult to assemble in the workshop.

Another drawback is that the wing can accidentally unhook back during installation, which can be dangerous and also cause the necessary damage and injuries.

The present invention aims to solve one or more of the above and other disadvantages.

To this end, the invention relates to a concealed hinge 25 for mounting a wing of a door or window in a fixed frame, which is composed of hollow frame profiles, characterized in that the hinge comprises a frame part intended to be attached to a wall of the frame profile and a hinge leaf wing part intended to be attached to the wing, the wing part being provided with a hook-shaped part which, with its free end, by means of

BE2019 / 5485 a shaft is hingedly connected to the frame part between two clamping blocks of the frame part in which the shaft is anchored with its ends, which clamping blocks are intended to pass through a recess in the aforementioned wall in a chamber of the aforementioned. the frame profile to be mounted and clamped by means of at least one clamping plate which is part of the concealed hinge and which is intended to be. to support the fixed frame on the aforementioned wall of the fixed frame and to be arranged between a clamping block and the hinge leaf. of the hinge member and through which a screw or the like is screwed into a clamping block to draw the clamping block towards itself.

The invention thus relates to a. concealed hinge that is partly built into a cavity of a frame profile that has been specially developed for this purpose in the frame profile, so that less space is required between the frame and the sash to be able to install the hinge. results in it. the fact that windows and doors can be realized with a slimmer appearance of the frame.

The concealed hinge is dimensioned such that the hook-shaped part is in the closed position of the

door or window, chap a ke .1: calibrate. in the aforementioned cavity of it fixed frame, where c iit hook-shaped share with it opera and from the door or window u i t. the cavity outwards

hinges.

A hinge according to the invention offers the advantage that it is easy to assemble.

BE2019 / 5485

It is sufficient to mill a chamber of appropriate shape and size into the wall of the frame profile on which the hinge is to be mounted and deep enough to create a chamber in which the clamping blocks can be fitted and clamped in by installing the clamping plates and screw the clamping blocks against it with clamping of some detail of the frame profile, more particularly with clamping of the aforementioned wall.

An advantage of a hinge according to the invention is that the hinge is compact and easy to assemble and this from the inside of the frame without parts having to be mounted in the frame beforehand.

Preferably, the frame part of the hinge is provided with a height adjustment with which the axial position of at least the bottom clamping block can be adjusted relative to the relevant clamping plate and thus in mounted condition relative to the recess in the frame profile, whereby for the height adjustment this clamping plate on the side facing the clamping block, it is provided with a leg which, in addition to the clamping block, extends into the chamber of the frame profile and wherein the height adjustment further comprises an adjusting screw with the point in. the direction of the aforementioned leg can be screwed in and screwed into the clamping block with the point resting on the leg.

This allows for easy height adjustment by simply unscrewing the adjustment screw more or less in the desired direction.

BE2019 / 5485

Preferably, the screw thread extends through the clamping block in a direction oblique to the axial direction of the shaft, moving away from the clamping plate in the direction of the point of. the adjusting screw that points towards the leg of the respective clamping plate.

In this way it can be screwed on with a screw at the adjusting screw. If the angle is easy, the wall of the frame profile on which the hinge is mounted can be slanted, so that there is enough free space around the screwdriver handle to hold the screwdriver and to rotate it.

The entrance to the screw thread is preferably located at a radial distance from the shaft at a location between the shaft and the side of the relevant clamping block facing the clamping plate.

has been applied in which the aforementioned t. ap can be clipped be in one direction parallel me ' t the support surface and 15 located in one flat, transverse on cæ cixicils J direction of the axis. Such a hinge makes it possibly that fitted the wing

of said tap in the wing part of a hinge pre-mounted on the frame and can be clipped at the same time in a direction perpendicular to the plane of the fixed frame and. so without movement parallel to this plane.

This also means that. no additional clearance must be provided for the latter movement when designing frame 25.

The wing can thus only be hooked into a vertically arranged frame with a horizontal movement without space being required for a vertical movement within the fixed frame.

BE2019 / 5485

This also facilitates mounting the wing in a workshop where the frame is flat on a horizontal table, by keeping the wing horizontal with its taps aligned above the clip mechanisms of the frame pre-mounted hinges and then lowering the wing until it snapping the studs.

Preferably, the clip mechanisms are such that the taps cannot be accidentally removed from them, so that accidents can be prevented.

Preferably, means are provided to release the trunnions from their clipped position if desired, if desired, for example for a repair or the like.

BE2019 / 5485 outside A towards the inside B is opened. In this case, the inside 3 is also called the hinge side B and the outside A. the non-hinge side Ά.

The invention is of course also applicable to an outwardly opening door, in which the hinge side and the non-hinge side are then exchanged.

The frame profiles 2 and the vent profiles and 5 are profiles with several hollow chambers, the profiles being thermally insulated and composed of a hollow shell 2a and 5a on the non-hinge side Ά of the door, a hollow shell 2b and 5b on the hinge side B of the door and in between a hollow intermediate shell 2c and 5c and wherein these shells are connected to each other by means of insulating bars 2d and 5d of a thermally insulating material.

The walls 2nd and 5th of the frame profile 2 and of the. vent profile 5, which are facing each other when the door is closed, are thus partly bounded by two insulating lanes 2d and 5d.

These walls are provided in a known manner with a stop lip, 2f and 5f respectively.

The hinge 1 is composed of a frame part 8 for fixing to the frame profile 2 and of a wing part 9 for fixing to the wing profile 5, which parts 8 and 9 are hinged together by means of

BE2019 / 5485

By way of example, five-chamber profiles are described and shown in the figures here, although the invention also applies to three-chamber profiles, in which there is no intermediate screed, but only two shells which are directly connected by insulating bars.

In the frame prototype 2 is one in the aforementioned wall from : recess 11 milled out at the location of one of the isc rational lanes 2d, which recess 11 forms an entrance

to a hollow chamber 2g of the frame profile 2. Due to the recess 11 in the case of a five-chamber profile, only

When closed, of the frame profile · 2 and the walls 2 of the wing profile 5 facing each other.

the door 4 is the hinge 1 in the aforementioned hollow chamber 2g in the space 12 between the to and 5th of the frame profile 2 and

By milling out the recess 11, certain details 13 of the frame profile 2 are released in the form of ribs, edges or the like, which can be used for clamping the frame part 8 of the hinge 1, depending on the design of the frame profile 2.

The frame part 8 of the hinge 1 contains two clamping blocks 14 which can be clamped at a distance from each other at the ends of the recess 11 in the frame profile 2 by means of a clamping plate 15 which rests on the frame profile 2 and in which a passage 16 is provided

BE2019 / 5485 for a screw 17 which is screwed into a screw hole 18 of the clamping blocks 14 in order to be able to tighten the clamping block 14 to clamp one or more of the aforementioned details 13.

The passage 16 is in the form of a slip hole which allows the clamping block 14 to be displaced axially from the shaft 10 relative to the clamping plate

15.

In the example shown, the clamping plate 15 is provided with two parallel edges 19, in the example respectively in the form of a curved lip 19a with which the clamping plate 15 can be hooked into a fitting groove 13a or other detailing on one side of the recess 11 and in the form of a tooth 19b with which the clamping plate 15 can rest on an edge 13b or other detailing on the other side of the recess 11.

in the example shown, clamping blocks 14 are provided with a projection 14a which is behind a roll-in tooth

13c or grasp any other detailing of the frame profile 2 and be attracted to it by screwing the aforementioned screw 17, as shown in Figure 11,

The clamping blocks 14 are provided with a bore 14b for the shaft 10 of the hinge 1, which bores 14b in the mounted state are aligned vertically in each other and are located at a certain depth D of the wall 2e in the hollow chamber 2g, because the shaft 10 is at a distance from the side of the clamping blocks 14 which faces the clamping plate 15.

BE2019 / 5485

The axis 10 is with. its ends are threaded into the bores 14b and the case clamped by a plurality of clamping screws 14c inserted into a radially threaded hole 14d in the clamping block. 14 are screwed or in any other way. The clamping blocks are thus fixed relative to each other, so that they cannot move unintentionally when mounted on a frame, as is the case with some known hinges.

The frame part 8 of the hinge 1 is provided with a height adjustment with which the height of the wing 6 in the fixed frame 3 can be controlled by axial displacement of the clamping blocks 14 relative to the clamping plates 15.

For this purpose, the clamping plates 15 are provided at their axial, away from each other ends, with a leg 20 which protrudes through the recess 11 in the frame profile 2 in the hollow chamber 2g of this profile 2 and located next to a clamping block 14 opposite one of the axis 10 facing outer end wall 14f of the clamping block 14.

The leg 20 of the lower clamping plate 15 rests on the lower end of the aforementioned recess 11 as shown in the cross section of Figure 13 or on some detail 13 of the chamber 2g.

The clamping blocks 14 are axially slidable in the chamber 2g by means of an adjusting screw 21 which can be screwed in and out in the clamping block 14 in the direction of the aforementioned leg 20 of the clamping plate 15e in the clamping block 14 with its point resting on the leg 20, bee

BE2019 / 5485 is preferred on a support surface of the leg 20 perpendicular to the adjusting screw 21.

The screw thread 14e extends through the clamping block 14 from an inner end wall to the outer end wall 14f. a direction that is oblique to the axial direction and away from the clerical plate towards the leg 20 and with its input for the adjusting screw 21 located at a radial distance from the shaft 10 and located between the shaft 10 and clamping plate 15.

As a result, this adjusting screw 21 is easily accessible for a screwdriver 22 or the like in order to be able to adjust the height of the wing part 9 of the hinge 1 with the wing 6 attached to it in the fixed frame 3 at a door 4 with a mounted and turned wing 6.

The wing part 9 of the hinge 1 a hinge leaf 23 dat on the aforementioned wall 5th of it 0 wing profile 5 confirmed and on which es one crochet vo rm.ig

is provided that with. its free end pivotable about the aforementioned axis IQ of the frame part 8 of the hinge 1 is arranged between the two clamping blocks 14 of the hinge 1.

and the third corner point at a transverse distance thereof and directed towards the stop lip 5f of the airfoil 5.

The two anchors 25a and 25b along the base of the aforementioned triangle 27 protrude completely or almost completely through the holes 26 in the airfoil 5 and are provided with an internal screw thread which is oriented transversely to the aforementioned wall 5e of the airfoil 5.

The third anchor 25c protrudes with its body into the airfoil 5 and has an end in the form of a semi-cylindrical stud 28 which protrudes with a certain length E from the wall 5e of the airfoil 5 in a direction transverse to this wall 5e and which has an enlarged head 28a on its end.

The tap 28 is provided with a flattening 28b on the side remote from the stop lip 5f.

The hinge leaf 23 has two longitudinal opposite edges, a first and a second edge 23a and 23b, respectively, which when mounted extend in the longitudinal direction of the airfoil 5.

At a short distance from the first edge 23a, two passages 23c are provided for screws 29 in the

BE2019 / 5485 the aforementioned screw anchors 25a and 25b can be rotated to fix the hinge blade 23, whereby the hinge blade 23 with its support surface 30 is pulled against the airfoil 5.

c

This support surface 30 is provided with a recessed recess 31 with an access 31a along the aforementioned second edge 23b of the hinge blade 23.

This recessed recess 31 contains a clip mechanism 32 in which the tap 28 of the third anchor 25 can be clipped in by hooking the tap 28 along the front access 31a of the recessed recess 3.1 into the clip mechanism 32 in a direction substantially parallel to the plane

1.5 of the support surface 30 and mainly transverse to the second edge. 23b or, therefore, in a plane extending substantially transversely of the axial direction of the shaft 10, the clip mechanism 32 being such that the clipped pin 28 can no longer be accidentally pulled out in the opposite direction.

In the illustrated example of Figure 15, this clip mechanism 32, which operates in one direction only, is formed by two pleated leaf springs 33, each with a clamped leg 33a on either side of the recessed recess 31 and a leg 33b extending at right angles thereto. the recessed recess 31 extends, the latter legs 33b being folded such that together they form, as it were, a double chalice-shaped channel 34 which extends 30 in a direction transverse to the second edge 23b of the hinge leaf 23 and which is provided with a first narrowed entry 34a at the end along the side of the

BE2019 / 5485 second rana 23b and of a second narrowed entrance 34b at the other end and of a wider central section 34c situated therebetween which can form a seat for the aforementioned protruding pin 28, at least for the part 5 of the tap 28 up to the widened flattened head 28a.

The leaf springs 33 are with the free end 33c of the leg

33a clamped in the hinge blade 23, in particular in this case between support points 35a and 35b, wherein the legs 33a 10 in the rest position extend substantially parallel to the second edge 23b.

In the rest position of Figure 15, the legs 33a sit against a stop 36 or at a small distance therefrom such that the legs 3Yes in the direction of. arrow p can be pushed away from the edge 23b, the support point 35b then serving as the inflection point, as illustrated in figure 16, but which stop 36 causes the legs 33a in the opposite direction of arrow P only to their

Bee it hooking on tap 28 along the serstf i input 34a from it can be a 34 the leaf springs 1 33 go inside pushed, why the mge clasped legs then thaw 'them

resilience around the inflection point 35b, away from the aforementioned stop 36, all this so that the

BE2019 / 5485 legs o 3b of the channel are first pushed apart as shown in figure 16 and then close again with the central part 34c around the hooked pin 28 by the resilience of the leaf springs 33 which spring back to their resting position as shown in figure 17.

Tap 28, however, cannot unintentionally release from the clip mechanism.

Indeed, if one tap 28 in the opposite direction of arrow? wish to release back from the clip mechanism 32, then. the leaf springs are pushed against the stop 36 which prevents the leaf springs from being pushed beyond their resting state and thereby the legs 33b of the channel 34 from being pushed apart.

In order to be able to release the tap 28 from the clip mechanism 32 nevertheless, in the example, means are provided to release the tap 28 from its clipped position from the clip mechanism 32, if desired.

For this purpose, from the opposite first edge 23a of the hinge blade 23, a passage 37 is provided in the hinge blade 23, which extends in the extension of the chalice-shaped channel 34 into the recessed recess 31.

It hinge 1 is provided with a regulation of the she division orthogonal distance from it hook-shaped part 24 until the hinge leaf 23. Hie the foot 24a is together with ee m in standing bar 39 limited

slidably mounted in the slot 23e.

The adjustment slat 39 is slidable in the longitudinal direction, for example in that longitudinal slip holes 39a are provided in the adjustment slat 39 and screws 39b screwed through these slip holes 39a into the upright rib 23d 30 of the hinge blade 23.

BE2019 / 5485

The longitudinal position of the adjustment slat 39 is adjustable, for example, by means of a control screw 40 with an eccentric cam 40a or other control means which, when rotated, can shift the adjustment slat 39 in one direction or another and which is accessible through an opening in the upright rib 23d.

In the foot 24a of the hook-shaped part 24, one or more slip holes 41 are provided which run at an angle to the support surface 30 of the hinge leaf 23 and the adjustment slat 39 is provided with one or more pins 42 which are slidably guided in the slip holes 41, all this in such a way that when the adjusting screw 40 is rotated, for example in a direction of rotation according to arrow S in figure 23, this entails a displacement of the adjustment slat 39 in the direction of arrow T and this also a displacement of the hook-shaped part 24 moves away from the hinge blade 23 according to the arrow or after the hinge blade when the adjusting screw 40 is rotated in the other

The adjusting screw 40 can be adjusted, for example, in the assembled state with the aid of a tool as in figure 24.

This control allows to control the closed position of the wing 6 relative to the fixed frame 3.

If necessary, the above-described regulation can also be made in another way

BE2019 / 5485

The mounting of a wing 6 in a fixed frame 3 of a door 4 by means of hinges 1 according to the invention is very simple and as follows.

In the frame 2, appropriate recesses 11 and chamber 2g are milled out for the frame part 8 of the hinges 1 to be mounted,

Holes are formed in corresponding places in wing 6

26 drilled for the anchors 25 and these are also already mounted.

It goes without saying that the recesses 11 and holes 26 with anchors 25 may also be provided in the factory beforehand.

Then the assembled hinges 1 can be fixed on the frame 2, after first the clamping plates 15 have been removed.

The clamping blocks 14 on the hinges 1 are herein inserted into the. recesses 11 are tilted and these clamping blocks 14 are anchored by means of the clamping plates 15 which are mounted on the frame and the hinges 1 are firmly fixed by tightening the clamping blocks 14 to the clamping plates 15 using the screws 17 as shown in the figures 8 to 12 and this with clamping in this case of the wall 2e along the inner circumference of the frame. The clamping plates 15 are located between the clamping blocks 14 and the hinge leaf 23 of the hinge part 9, at least when the hinge 1 is in a closed position.

BE2019 / 5485

Because there are, inter alia, two clamping plates 15 and the clamping blocks 14 cannot move mutually, the mounting of the clamping plates 1b is very simple.

then the hinges 1 are turned to their closed position as shown in figure 14, whereby h. support surface oO of the hinge blades 23 approximately

parallel to lie with the wall 2nd from the frame profile 2 wa ar op the hinges 1 are you mounted, And so first red deer On h et plane of the c ie ' ur opening, Causing

the access 3ia of the recessed portion 31 with the clip mechanism 32 contained therein becomes accessible along the hinge B of the door 4.

Then, the wing 6 is held approximately parallel to the plane of the door opening and inserted into the fixed frame 3 in a direction perpendicular thereto and clipped by snapping the wing 6 with its taps 28 into the clip mechanisms 32.

The wing 6 can then be released, since the studs z8 are clipped and can no longer come off unintentionally,

The wing 6 can then be turned open about the hinges

1 to screw onto the wing 6 by screwing the screws 29 into the screw anchors 25a and 2dn, whereby the hinge leaf 23 is also clamped against the head 28a of the pin 28 by the aforementioned leverage thanks to the bevel 30a of the support surface 30 of it. hinge leaf

23, whereby a strong three-point connection is realized on the wing with the three anchors 25.

BE2019 / 5485

It goes without saying that a two-point connection with one anchor 25c with a spigot 28 and with another anchor 25a for a screw 29 may suffice, the latter anchor 25a being located at a greater distance from the mounting lip 5f than the anchor 25c. with tap 28.

After the confirmation wing 6 on the hinge • and 1 can. the scheme of the position of the wing 6 in the V a st Box 3 is implemented, where for this reg eling the wing 6 is turned around the position from it wing part 9 of the hinges 1 relative from it frame part 8 to be able to arrange. A first scheme consists of to the height from the

wing 6 in the fixed frame 3 by, as shown in figure 13, screwing the adjusting screw 21 of the frame part 8 of the lower clamping block 14 more or less, which can be done in a simple manner with a screwdriver 22 or the like in that this adjusting screw 21 is located in a location which is easily accessible with the wing in mounted condition as shown in figure 1.

A second arrangement has to adjust the position of the wing 6 by hinging 1 the screws covering the side in the fixed frame 3 which can slightly loosen the wing part 9 of the 39b so that the position of the hook-shaped part 24 in relation to the hinge leaf 23 can be adjusted and then turn the adjusting screw 40 with the eccentric cam 40a so that the foot 24a of the hook-shaped part

BE2019 / 5485 is moved deeper into or further out of the slot 23e as shown in Figures 23 and 24.

After this lateral adjustment, the screws 39b can be tightened to fix the vent 6 to the hinges 1,

If it is necessary to release the wing 6 from the fixed frame, it is sufficient to remove the screws 29 from the

anchors 25a and 25b too to turn and · ί to delete and then the tapping 28 on the flesh ugel 6 out it clips me c h a n i s m e 32 to be making love with using it tools 38 around the legs 33b from the leaf springs 33 from

push each other as shown in figures 21 and 22.

It goes without saying that the frame part 8 of the hinge 1 as described above can also be combined with another wing part 9, for example of a classic hinge or vice versa, that a wing part 9 of a hinge 1 as described above can be combined with another frame part 8, for example of a classic screen.

The anchors 25a, 25b do not necessarily have to be clamping anchors, but can also be replaced, for example, by blind rivet nuts, threaded bushes, tightening plates or any other means for fastening a screw.

The clamping anchor 25c for fixing the stud 28 can also be replaced, for example, by a screw, rivet or the like,
