Description

Concealed hinge for a door or window and door or window equipped with it and method for mounting a sash 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 about 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 built up of hollow profiles composed of several profiles, in particular two outer shells, respectively on the outside and on the inside of the door or window, and possibly an intermediate shell, the shells being interconnected by means of so-called insulating bars which form a thermal interruption between both sides of the door or window.

The frame profiles and the vent profiles are provided with a lip with which these profiles overlap each other when the door or window is closed and on which a seal is fitted 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

BE2018 / 5600 or 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 an axis.

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 the door or window must be designed in such a way that there is sufficient space for the hinges between the two, which means that wide profiles are needed, which goes against the tendency to use as narrow profiles as possible.

For mounting the hinge on the frame, holes are drilled in a known manner on the construction site in the aforementioned wall of the frame, in which blind rivet nuts are fastened with an internal thread into which screws can be screwed for fixing the frame part of the hinge to the frame.

This is a job that must be carried out with the necessary attention and care by well-trained personnel

BE2018 / 5600 technicians, which also implies that this takes a relatively long time.

On the side of the wing it is known to provide a tap-hole connection between the wing and a hinge already pre-mounted on the frame, whereby a tap with a widened head must be hooked in a vertically extending slotted hole with the predetermined on the frame-mounted hinges that are turned to the open position.

The slotted holes are provided with an access for this, whereby the wing is hooked by a horizontal movement of the wing towards the frame, after which the wing can be lowered vertically in order to hook the tap into the slotted hole, so that the wing then it is possible to release 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 to have sufficient room for movement with the wing for hooking the wing, which implies that wide frames are required for this. 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.

BE2018 / 5600

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 for fixing 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 which is intended to be attached to a wall of the frame profile and a wing part intended to be attached to the wing, the wing part comprising a hook-shaped part which, with its free end, is hingedly connected to the frame part by means of a shaft, between two clamping blocks of the frame part in which the shaft is its ends are anchored, which clamping blocks are intended to be mounted via a recess in the aforementioned wall in a chamber of the frame profile and to be clamped by means of at least one clamping plate resting on the fixed frame and through which a screw or the like is arranged to attract a clamping block toward itself.

The invention thus relates to a concealed hinge which is partly built into a cavity of a frame profile which has been specially developed for this purpose in the frame profile, in order to ensure that less space is required between the frame and the wing around the hinge. build in, resulting in the fact that

BE2018 / 5600 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 state of the door or window, mainly in the aforementioned cavity of the fixed frame, this hook-shaped part hinging out of the cavity when the door or window is opened .

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

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.

The frame part of the hinge is preferably provided with a height adjustment with which the axial position of at least the lower clamping block can be adjusted with respect to the relevant clamping plate and thus in mounted condition with respect 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 extends next to the clamping block into the chamber of the frame profile and wherein the height adjustment further comprises an adjusting screw pointing with the point in the direction of

BE2018 / 5600 the aforementioned leg can be screwed into and unscrewed in a screw thread in 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.

Preferably, the screw thread extends through the clamping block in a direction obliquely to the axial direction of the shaft, moving away from the clamping plate towards the point of the set screw facing the leg of the shaft. relevant clamping plate.

In this way, the adjustment screw can be easily screwed in with a screwdriver which can then be tilted relative to the wall of the frame profile on which the hinge is mounted, so that there is enough free space around the screwdriver handle to hold the screwdriver. and to be able to rotate.

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.

Thus, the adjusting screws of the hinges are easily accessible with a mounted and turned wing.

The invention also relates to a door or window with a fixed frame in which a wing is hinged

BE2018 / 5600 suspended by means of concealed hinges according to the invention, the fixed frame being composed of hollow frame profiles, characterized in that the frame profiles at the hinges are provided with a recess giving access to a chamber of the frame profile in which the hinges with their clamping blocks are clamped in by means of the clamping plates and the screws that are screwed into the clamping blocks through the clamping plates.

The invention also relates in particular to a concealed hinge, the wing part of which is provided with a hinge leaf which is intended to be fixed with a supporting surface against a wall of a wing profile, wherein the hinge is further provided with an anchor intended to to be anchored in a hole in the aforementioned wall and which is provided with a tap and wherein the hinge leaf along an edge in its supporting surface is provided with a recessed recess, in which a clipping mechanism is arranged in which the aforementioned tap can be clipped in a direction parallel with the support surface and located in a plane transverse to the axial direction of the shaft.

Such a hinge allows the wing provided with a aforementioned trunnion to be hooked into the wing part of a hinge pre-mounted on the frame and at the same time clipped in a direction perpendicular to the plane of the fixed frame and thus without movement parallel to this plane.

BE2018 / 5600

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

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

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

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

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

According to a preferred feature, the support surface of the hinge leaf is provided with a chamfer or rounding over a certain width from its aforementioned edge and the hinge leaf on its opposite edge is provided with one or more holes for screws for fixing the hinge leaf in corresponding

BE2018 / 5600 anchors pre-anchored in the aforementioned wall of the airfoil.

This chamfer ensures that when the aforementioned screws are screwed into the anchors, the hinge blade is tilted and thereby clamped against the head of a stud on the opposite edge of the hinge blade, which ensures a firm connection.

According to another aspect of the invention, the wing part of the hinge is provided with a movable part, the lateral distance from which the hinge leaf is adjustable.

This makes it possible to control the lateral position of the sash in the fixed frame, which is necessary in view of the inevitable tolerances in the manufacture of the door or window and to compensate for deformations due to the weight of the door.

The invention also relates to a door or window with a fixed frame in which a wing is hingedly suspended by means of concealed hinges as described above, wherein the wing is composed of wing profiles with a wall with a stop lip and in which the hinges are fixed with their hinge leaf said wall by means of at least two anchors, at least one of which is provided with the aforementioned stud protruding from the wall and at least one other anchor provided for fixing the hinge leaf with a screw through a said passage in the hinge leaf.

BE2018 / 5600

Figure 1 shows a concealed hinge 1 according to the invention positioned between a frame profile 2 of a fixed frame 3 of a door 4 and a wing profile 5 of a rotatable wing 6 of the door 4.

In the example shown, an inward opening door 4 is shown, in which the wing 6 is opened from the outside A to the inside B. In this case, the inside B is also called the hinge side B and the outside A the non-hinge side A.

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 wing profiles 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 A of the door, a hollow shell 2b and 5b on the hinge side B of the door and between them 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 2e and 5e of the frame profile 2 and of the vent profile 5, which face the door when 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.

BE2018 / 5600

The hinge 1 is composed of a frame part 8 for mounting on the frame profile 2 and of a wing part 9 for mounting on the wing profile 5, which parts 8 and 9 are hinged together by means of a shaft 10.

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

In the frame profile 2, a recess 11 is milled in the aforementioned wall 2e at the location of one of the insulating lanes 2d, which recess 11 forms an access to a hollow chamber 2g of the frame profile 2. The recess 11 in the case of a five-chamber profile only in a single insulating bar 2d, the second insulating bar 2d remains intact, so that no thermal bridge can form at the location of the recess 11.

When the door 4 is closed, the hinge 1 is concealed in the aforementioned hollow chamber 2g of the frame profile 2 and in the space 12 between the mutually facing walls 2e and 5e of the frame profile 2 and of the vent profile 5.

By milling 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 .

BE2018 / 5600

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 for a screw 17 which is screwed into a screw hole 18 of the clamping blocks 14 so as 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 illustrated example, the clamping blocks 14 are provided with a projection 14a which can engage behind a roll-in tooth 13c or another detail of the frame profile 2 and can be attracted against it by

screw on of the aforementioned screw 17, like displayed in figure 11.

The clamping blocks 14 are provided with a bore 14b for the shaft 10 of the hinge 1, which bores 14b

BE2018 / 5600 mounted position are vertically aligned 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 facing the clamping plate 15 .

The shaft 10 is provided with its ends in the bores 14b and clamped therein by means of clamping screws 14c screwed into a radial threaded hole 14d in the clamping block 14 or in any other way.

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 adjusted 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 slidable in the axial direction in the chamber 2g by means of an adjusting screw 21 which moves in the direction of the aforementioned leg 20 of the clamping plate 15

BE2018 / 5600 a screw thread 14e can be screwed in and out in the clamping block 14 with its point resting on the leg 20, preferably 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 in a direction oblique to the axial direction and away from the clamping plate to the leg 20 and with its input for the set screw 21 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 wing 6 mounted and opened.

The wing part 9 of the hinge 1 comprises a hinge leaf 23 which is mounted on the aforementioned wall 5e of the airfoil 5 and on which a hook-shaped part 24 is provided, which hinges with its free end around the aforementioned axis 10 of the frame part 8 of the hinge 1 is arranged between the two clamping blocks 14 of the hinge 1.

For the attachment of the vent part 9 to the vent profile 5, this vent profile 5, as shown in figure 2, is provided with three anchors 25, 25a, 25b and 25c respectively, for example in the form of clamping anchors, blind rivet nuts, screw bushings, rivets or the like,

BE2018 / 5600 preferably clamp anchors, which are knownly arranged through holes 26 which are pre-arranged in the relevant wall 5e of the airfoil 5 and which are positioned at the vertices of a triangle 27 as shown in the dashed line in figure 2, the base of which extends in the longitudinal direction of the airfoil 5 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.

BE2018 / 5600

At a short distance from the first edge 23a, two passages 23c are provided for screws 29 which can be screwed into the aforementioned screw anchors 25a and 25b to fix the hinge leaf 23, whereby the hinge leaf 23 with its support surface 30 is pulled against the airfoil 5.

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

This recessed recess 31 contains a clipping mechanism 32 in which the tap 28 of the third anchor 25 can be clipped in by hooking the tap 28 along the aforementioned access 31a of the recessed recess 31 into the clipping mechanism 32 in a direction substantially parallel to the plane of the support surface 30 and substantially transverse to the second edge 23b or thus in a plane which extends substantially transversely of the axial direction of the shaft 10, which clipping mechanism 32 is such that the clipped pin 28 can no longer be accidentally pulled out in the opposite direction .

This clip mechanism 32, which operates in one direction only, is in the illustrated example of Figure 15 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 perpendicular thereto extending into the recessed recess 31, the latter legs 33b being folded in such a way that they together form, as it were, a double chalice-shaped channel 34 which extends in a direction transverse to the second edge 23b of the

BE2018 / 5600 hinge leaf 23 and which is provided with a first narrowed entrance 34a at the end along the side of the second edge 23b and with a second narrowed entrance 34b at the other end and a wider central section 34c which can seat for the aforementioned protruding stud 28, at least for the portion of the stud 28 to the widened flattened head 28a.

The leaf springs 33 are clamped with the free end 33c of the leg 33a in the hinge leaf 23, in particular in this case between support points 35a and 35b, the legs 33a in the rest position extending substantially parallel to the second edge 23b.

In the rest position of Figure 15, the legs 33a sit against a stop 36 or a short distance therefrom such that the legs 33a can be pushed in the direction of arrow P away from the edge 23b, the support point 35b then serving as the inflection point as illustrated in Figure 16, but which stop 36 ensures that the legs 33a in the opposite direction of arrow P can only return to their original resting state or can only be pushed beyond this resting state by a limited distance.

It is clear that in the aforementioned rest state the channel 34 is the narrowest and that when the leaf springs 33 are pushed in the channel 34 opens as in figure 16.

When hooking the pin 28 along the first entrance 34a of the channel 34, the leaf springs 33 are pushed in, the clamped legs then being moved through their

BE2018 / 5600 can bend resilience around the inflection point 35b, away from the aforementioned stop 36, all this in such a way that the legs 33b of the channel 34 are first pushed apart as shown in figure 16 and then again with the central part 34c around the hooked pin 28 by the resilience of the leaf springs 33 springing back to their rest position as shown in Figure 17.

Tap 28, however, cannot unintentionally release from clipping mechanism 32.

Indeed, if one wishes to release the tap 28 in the reverse direction of arrow P from the clip mechanism 32, the leaf springs are pushed against the stop 36, which prevents the leaf springs from being pushed past their resting state and thereby the legs 33b from the channel 34 could be pushed apart.

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

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.

The legs 33b of the cup-shaped channel 34 can be pushed apart via this passage 37 by means of a

BE2018 / 5600 tool 38 with a head 38a sufficiently wide to push the legs 33b apart along the second entrance 34b of the channel 34 as shown in figure 21, in which case the leaf springs 33 again around the support point 35b of the stop 36 bend away, as a result of which the first entrance 34a of the channel 34 also opens and the tap 28 at the same time

using the same tools 38 from it clip mechanism 32 can be pushed through with this tool 38 the flattening 28b of the tap 28 to to push as shown in figure 21.

In the example shown, the tool 38 is formed by a threaded rod 38b which is screwed into the aforementioned passage 37 and which is inserted into the recess 31 with its head 38a and which can be screwed in and out with a screwdriver 22 or the like as shown in figure 22.

Also, due to the widened head 28a of the tap 28, the tap 28 cannot be unintentionally pulled in its axial direction from the clipping mechanism 32.

The supporting surface 30 of the hinge leaf 23 is provided over a certain width from its second edge 23b with a bevel 30a over an angle H of, for example, 3 to 4 ° as indicated in figure 8, or a rounding, such that during screwing of the screws 29 along the first edge 23a of the hinge blade 23, the hinge blade 23 in the direction of arrow Q, as indicated in Figure 18, tilts around the kink line 30b in the transition from between the flat portion of the support surface 30 and the chamfer 30a, passing the hinge leaf 23 through the

BE2018 / 5600 lever effect against the widened head 28a of the spigot 28 is tightened, so that the hinge blade 23 is firmly anchored to the airfoil at three points at the location of the anchors 25. Here, all clearances required to move smoothly over the spigot 28 to be hooked when screwed in.

The hook-shaped part 24 of the wing part 9 of the hinge 1 is movably mounted on the hinge leaf 23 along the first edge 23a of the hinge leaf 23.

To this end, the movable hook-shaped part 24 is provided with a lath-shaped foot 24a and the hinge leaf 23 is provided with an upright rib 23d with a groove 23e therein which extends in the longitudinal direction of the hinge leaf 23 and in which the foot 24a of the hook-shaped part 24 in is arranged with the hook-shaped part directed towards the second edge 23b of the hinge leaf 23.

The hinge 1 is provided with an adjustment of the lateral orthogonal distance from the hook-shaped part 24 to the hinge leaf 23.

For this purpose, the foot 24a, together with an adjusting slat 39, is arranged in a slidable manner in the slot 23e.

The adjustment slat 39 is slidable in the longitudinal direction, for example because 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 of the hinge blade 23.

BE2018 / 5600

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 turned, 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 away from the hinge leaf 23 according to arrow U or towards the hinge leaf when the adjusting screw 40 is rotated in the other direction of rotation.

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 realized in another way.

BE2018 / 5600

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

6 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 can 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 are tilted at the hinges 1 in the recesses 11 and these clamping blocks 14 are anchored by means of the clamping plates 15 which are mounted on the frame 2 and the hinges 1 are firmly fixed by attaching the clamping blocks 14 to the clamping plates 15 using the screws 17 as shown in figures 8 to 12.

The hinges 1 are then rotated to their closed position as shown in figure 14, wherein the support surface 30 of the hinge blades 23 comes to lie approximately parallel to the wall 2e of the

BE2018 / 5600 frame profile 2 on which the hinges 1 are mounted, and thus perpendicular to the plane of the door opening, so that the access 31a of the recessed part 31 with the clip mechanism 32 present therein is accessible along the hinge side 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 taps 28 are clipped on and can no longer come off unintentionally.

The wing 6 can then be turned open to screw the hinges 1 to the wing 6 by screwing the screws 29 into the screw anchors 25a and 25b, whereby the hinge leaf 23 is also clamped against the head 28a of the stud 28 by the aforementioned leverage thanks to the bevel 30a of the support surface 30 of the hinge leaf 23, whereby a strong three-point connection is realized on the wing with the three anchors 25.

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

After the mounting of the wing 6 on the hinges 1, the adjustment of the position of the wing 6 can be fixed in it

BE2018 / 5600 frame 3, for this control the wing 6 is opened to be able to adjust the position of the wing part of the hinges 1 relative to the frame part 8.

A first wing 6 frame part 8 control shown consists in adjusting the height of the fixed frame 3 in figure 13, more screwing the adjusting screw of the lower clamping block 14, which is easily done by, such as from or less it on with a screwdriver 22 or the like in that this adjusting screw 21 is located in a place that is easily accessible with the wing in mounted condition as shown in figure

1.

A second control relates to the lateral position of the wing 6 in the fixed frame 3, which can be adjusted by slightly loosening the screws 39b on the wing part 9 of the hinges 1 so that the position of the hook-shaped part 24 relative to the hinge blade 23 can be adjusted and then rotate the adjustment screw 40 with the eccentric cam 40a to move the foot 24a of the hook-shaped portion 24 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

BE2018 / 5600

anchors 25a and 25b loose to to spin and to delete and thereafter the tapping 28 on the wing 6 out it clip mechanism ism 32 at liberate 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 hinge.

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.

Also the clamping anchor 25c for fixing the stud 28 can for instance be replaced by a screw, rivet or the like.

The present invention is not limited to the embodiments described by way of example and shown in the figures, but a concealed hinge according to the invention and a door or window equipped with it can be realized in all shapes and sizes without departing from the scope of the invention.
