EP2252751B1 - Espagnolette fitting for window or door - Google Patents

Abstract

The invention relates to a window or a door comprising wings (2) and frames (3) and comprising an espagnolette fitting (5) in which this espagnolette fitting (5) is composed of at least two fitting units (8, 9, 10) that couple together in a moveable fashion, wherein the effective overall length of the fitting units (8, 9, 10) can be adjusted to different length dimensions of the wing dimensions (4a, 4b) of the window or door by way of coupling element pairs (15) that can be adjustably engaged with one another in fine steps in mutually overlapping form-locking fashion. Each of the coupling element pairs (15) is formed by a short coupling element (26) at one espagnolette (18), said short coupling element determining an effective or pre-determined form-locked engagement length (48) and a long coupling element (29) at the other espagnolette (16) tailored according to a possible adjustment length in the adjustment range or application tolerance range (46). It is provided that the coupling element (29) and/or the associated espagnolette (16) is over-gripped or under-gripped by the espagnolette (18) that comprises the short coupling element (26) determining the form-lock engagement length (48) along the entire application tolerance range (46) at a minimal length dimension within the application tolerance range (46) so that the coupling element (29) remains effective along its entire length (45).

Description

The application relates to a window or a door according to the preamble of claim 1.

A window of this kind is from eg DE 19616271 A1 already known. It is provided that the adjoining fitting construction units form a drive rod fitting. The drive rods are drive-connected, wherein the effective total length of the fitting assemblies on finely adjustable adjustable mutually overlapping positive engagement engageable coupling element pairings can be tuned to different length dimensions of the wing dimensions of the window.

Coupling element pairings are provided between the mutually facing ends of the drive rods of the adjacent fitting assemblies. A coupling element pairing is effected by an effective or predetermined interlocking length-determining short coupling element on the one drive rod. A second coupling element pairing is formed by a matched to a possible adjustment length in the adjustment range long coupling element on the other drive rod.

For adaptation, it is provided that the long coupling element is cut back to the desired level and coupled with the adjacent fitting construction units.

Another interpretation of espagnolette fittings for windows or doors with sash and frame is still common in the German magazine " Baubeschlag-Magazin ", Issue 7, 1975 on page 105 illustrated and explained. It uses for the purpose of easy and simple adjustment of the fitting assembly units to different window and door sizes (wing height and width) finely adjustable with each other in overlapping form-fitting engageable coupling element pairings in the form of directly intermeshing fine teeth, the zug- in the direction of movement of the drive rods and are designed pressure-resistant. The effective or predetermined - short - FormschlusseingriffsLänge determining coupling element of each coupling element pairing is in this case at the free end of the drive rod of each Eckbeschlagsbaueinheit, while At both ends of the drive rod of the middle fitting assembly or drive assembly a possible adjustment length determining - long - coupling element for a coupling element pairing is.

The practical experience has shown on the one hand that the way the usual today equipment of windows or doors with the espagnolette fittings, and in particular the mounting or the stop of the same on the Falzumfangsflächen the sash, although the traditional - artisanal - manufacturing method of windows and doors largely corresponds. On the other hand, it has been found, however, that the hitherto customary conception of at least the driving rod fittings formed on the operating side of the wing of windows or doors and of three fitting units to be coupled with each other in terms of movement, especially in large-scale - industrially - operated window and door production on application or attack technical Limits are encountered. This is mainly because the installation or attack of each other the complete espagnolette fitting forming different fitting assemblies can not be incorporated early in the production process during the course of production of the casement, but also must be done here as a whole on the finally finished set casement.

A disadvantage of both embodiments is that the Ablängvorgänge the drive rods bring a lot of time with it.

In the DE 2313690 A1 is therefore already known an embodiment in which a single fitting assembly is provided. This can be adapted to different sash dimensions over a common overlapping area of two drive rod sections, which have form-locking engagement means in the form of fine gears. For this purpose, a fastening means holding the fine toothings is released so that the drive rod sections can be displaced relative to each other. If the desired dimension of the drive rods or the fitting assembly units is set, the fastener is tightened again. As a result, a cutting to length of the fitting assembly can be dispensed with and the fitting assembly can be adapted to the wing dimensions within an intended grid dimension of the fitting assembly.

The object of the invention is to develop a window or a door to the effect that the cutting to length of the drive rods can be omitted and that nevertheless several building hardware units can be provided, which are selectively connected to each other and which can be adapted to the wing dimensions.

To solve this problem in a generic window or a generic door, the invention provides for the realization of the characterizing part of claim 1.

The increased overlap area of the two drive rods makes a cutting unnecessary, since the two drive rods can completely cover each other in the first smallest Flügelfalzhöhe and in the second conceivable maximum position only with the Formschlusseinggrsgrngs determining short coupling element.

It is provided in a development that the drive rod, which has the long coupling element, has a U-shaped cross-section. This configuration makes it possible to produce the drive rod of a material with a smaller cross-section, without a buckling of the drive rod is to be feared under load.

It can also be provided that the free U-legs of the U-shaped cross section point away from the second overlapping drive rod. This avoids that when coupling the drive rods, the overlapping drive rod rests only on the webs.

When the drive rods are received in a fitting groove of the wing and the U-legs point in the direction of the groove bottom, the last to be mounted on the wing and overlapping drive rod can be provided with a simple rectangular cross-section.

In order to improve the dimensional stability of the drive rod is provided that the coupling element is formed by a fine toothing, which is attached to the drive rod at the longitudinal side edges of a slot.

To ensure that the toothings mesh at full height is provided. in that the longitudinal side edges of the oblong hole extend in alignment with the U-legs of the drive rod, so that they can reach through engaging toothing between the U-leg.

If the fine toothing is additionally formed on the inner sides of the U-legs of the drive rod, the maximum transmission force of the coupling connection can be further increased.

In order to maximize the stability of the drive rod is still provided that the fine toothing consists of interlocking mushroom-shaped teeth, so that the fine toothing acts positively in two levels. The first level is the longitudinal direction of the drive rod and the second level is the plane of the U-bar of the drive rod.

In order to produce the fine teeth on the overlapping drive rod as simple as possible can be provided that the fine teeth on the drive rod is attached to a coupling piece which engages over the drive rod and which has a substantially T-shaped cross-section.

In order to easily handle the items of the second building hardware assembly and to better perform the drive rod, the drive rod is associated with a fitting assembly, which has a housing, wherein the housing has a substantially U-shaped cross-section.

In the development of the aforementioned embodiment, it is also still for mounting on the window of advantage that the free U-legs of the housing are perpendicular to Flügelfalzfläche and that the U-legs form a guide for the drive rod, so that the drive rods lateral support to get.

In order to ensure the accessibility of the drive rods during assembly of the U-legs of the housing connecting U-web is assigned to the groove bottom of the fitting, so that an accessible from the folding surface ago channel is formed.

In order to obtain a conclusion on the wing corner and to stabilize the housing is provided that on the housing in the corner area a cover on the Housing is provided, which covers the lying between the U-legs area.

A particularly advantageous embodiment, is claimed for the independent protection, provides that the cover has an opening extending along the Flügelfalzes, which forms a guide for a rail, which along the opening verschiebar forms a cover of the housing. As a result, the housing can be closed against a folding surface. If the coupling connection is inside the housing, then this is also covered. The attachment of an additional faceplate on the housing is eliminated.

If the opening is at the level of the free ends of the U-legs of the housing, then the rail can also help to stabilize the housing.

In order to maximize the stability of the rail in tight spaces, the opening and the rail are provided with a coordinated T-shaped cross-section.

A particularly preferred embodiment also provides that the rail is provided with markings that simplify a length reduction. This can be done, for example, by underside-mounted markings that give an indication of where to cut to length.

The cutting to length can be particularly simple if the markings are designed as predetermined breaking points, since no further tools are required.

In order to keep the rail in the mounted position, it is provided that the rail has a coupling device at the end facing the fitting assembly.

To keep the fitting arrangement securely in the fitting groove is provided that the fitting assembly has a drive rod covering the face plate, which is provided close to the second fitting assembly end facing with a bore, the face plate, the drive rod in a middle position of the drive rod by more than projected half a stroke length of the drive rod and wherein a fastener passes through the hole and the slot in the drive rod.

In order to achieve a locking of the window or the door on an adjacent wing leg is one of the fitting construction units a Eckumlenkung, in which a deflection member is connected to the drive rod, which is guided in an angular housing and a pushing movement on an angle to the drive rod slidable in the housing guided drive rod allows.

In order to be able to connect further fitting construction units such as, for example, an opening device, it is advantageous if the drive rod has a coupling element for a further fitting assembly.

Alternatively, it can be provided that one of the fitting assemblies is a closer, which has a perpendicular to an adjacent sash emerging latch. This is for example in a rotary wing a particularly simple embodiment of the espagnolette fitting.

Finally, the invention also relates to a driving rod fitting which is suitable for equipping a wing of a window or door according to one of the preceding claims.

In the schematic representation after Fig. 1 is the sash of a window 1 with 2 and the frame labeled 3. The wing frame 2 is made up of four profile beams 2 a, 2 b, 2 c, 2 d, each extending at right angles to one another, in that their mutually facing ends are each rigidly joined by so-called corner joints. In the illustrated embodiment, the corner joints are designed as Miter corner joints. But it is quite possible, the profile rails 2a to 2d by other types of corner joints rigidly together to form the sash 1.

For a long time, it is common practice to complete the casement 2 for windows or doors in the desired or required size, ie with very different Flügelfalzhöhe 4 a and 4b Flügelfalzbreite completely before they are then equipped with the additional necessary for their respective function fittings and about this with the associated frame 3 and its fittings are brought into operative connection.

The purpose of the fittings is to ensure the proper opening and closing functions of the window or door. You then need to ensure not only different possibilities of movement of the sash 2 relative to the frame 3. Rather, between the sash 2 and frame 3 also drive rod fittings 5 must be installed and made effective, which not only the setting of the different possibilities of movement of the sash 2 relative to the frame 3 useful are, but also to ensure a locking of the voltage applied in the closed position on the frame 3 sash 2.

At least at the so-called operating side 7 of the sash 1, which in the Fig. 1 is determined by the profile spar 2a, therefore, the installation of an espagnolette fitting 5 along the Falzumfangsfläche 6 of the sash 2 is required. The provided for the installation of the espagnolette 5 profiling of Falzumfangsfläche 6 is - preferably - in the longitudinal direction of all the sash 1 forming profile beams 2a to 2d the same. When required, therefore, not only the operating side of the wing 1, so the profile spar 2a, but also all other profile beams 2b, 2c and 2d of the same so-called Anschlußbaueinheiten the espagnolette fitting 5 can be assigned.

In the Fig. 1 is merely to see that the operating side of the wing 1 attributable or associated espagnolette fitting 5 of three mutually to be coupled in terms of movement fitting assembly 8, 9 and 10 is to be formed or can. Of these fitting assemblies 8, 9 and 10, the fitting assembly 10 is designed as a so-called corner fitting assemblies or Eckumlenkung, which can align in the region of a corner joint of the operating side 7 of the sash 2 on the Falzumfangsfläche 6 and fasten.

The lower fitting assembly 9 is designed as a closer, which engages with a bolt 11 in a frame-side locking engagement, not shown here. The between the fitting assembly 9 and 10 to be arranged middle fitting assembly 8 is designed as a so-called drive assembly that carries the actuator 10 for the entire espagnolette fitting 5, which z. B. is manually movable by an actuating handle also not shown here.

While the fitting construction units 8, 9 and 10 can be accommodated and fastened on themselves in the step or profile groove provided along the seam perimeter surface 6 of the profile rails 2, 2c and 2d - the so-called EURONUT - it must be located on the operating side 7 of the casement 2 Profilholm 2a are provided in a known manner additionally with recesses which connect to the step or profile groove and can accommodate the actuator 10 serving as a drive assembly fitting assembly 8.

Essential criterion of at least the operating side 7 of the casement 2 attributable espagnolette 5 is that the effective total length of all three mutually bewegungsmäßig to be coupled fitting assemblies 8, 9 and 10 easily and feinstufig to completely different length dimensions of the operating side 7 of the sash 2 - in the example so completely different Flügelfalzhöhen 4a - vote. For this purpose, special precautions to the three to be coupled to each other in terms of movement fitting assemblies 8, 9 and 10 - ie both the drive assembly 8 and the two fitting assemblies 9 and 10 - necessary. Namely, at least between the mutually facing ends of each of the fitting assembly 8, 9 and 10 associated drive rods special coupling element pairings provided as below with reference to Fig. 2 the example of fitting assembly 8 and 10 will be explained.

The fitting assembly 10 is formed as a corner 12 and has a first leg 13 and a second leg 14, each orthogonal to each other and the profile beams 2a and 2c are assigned. Both the corner drive 12 as well as the drive assembly 8 each have two finely adjustable adjustable mutually overlapping positive engagement engageable and thereby tensile and compressive in the direction of movement, the coupling element pairing 15 forming coupling elements 26 and 26, the more detailed below with respect to their arrangement and training be explained. Preference is given to the use of directly intermeshing fine teeth, which are already known as coupling element pairings 15 at least between the drive rods of espagnolette fittings.

The drive rod 18 of the drive assembly 8 has a flat rectangular cross section and is provided at its end 19 with two holes 20, 21. The drive rod 18 is associated with a coupling piece 22 which has two of the rear side 23 projecting coupling lugs 24, 25 ( Fig. 5 ). The coupling lugs 24, 25 are designed in different sizes and adapted to the holes 20, 21 in the drive rod 18, so that there is only a single installation position. This gives the drive rod 18, the fine teeth 26, which is not necessary in a variety of applications of the respective window, since the Beschlagbaueinheiten 9, 10 are not provided.

Evidently the Fig. 2 the coupling piece 22 is mounted so that it engages over the drive rod 16. In this case, the coupling piece 22 has a substantially T-shaped cross-section. In conjunction with the FIGS. 3, 4 . 5 and 6 Further details of the coupling element pairing become clear. The drive rod 16 has a U-shaped cross-section, which makes it possible to produce the drive rod 16 made of a material with a smaller cross section or a smaller wall thickness without buckling of the drive rod 16 is to be feared under load. Preferably, the drive rod 16 is made by a roll bending process of thin metal sheet and provided by punching with a slot 27. The longitudinal side edges 28 of the slot 27 are provided with a fine toothing 29, which is evidently the Fig. 5 on the inner sides 30 of the U-leg 31 of the drive rod 16 continues. For this purpose, the longitudinal side edges 28 of the slot 27 are aligned with the U-legs 31 of the drive rod 16. Overall, an enlarged depth of engagement of the fine teeth 26,29 is achieved, which on the one hand increases the maximum transfer force of the coupling connection and on the other hand, a slipping out of the coupling piece 22 difficult.

In the Fig. 4 is a sectional view of the coupling connection reproduced. The free U-legs 31 of the drive rod 16 are directed away from the overlapping drive rod 18 and point in the direction of the groove bottom 32 of a stepped fitting groove 33 which is mounted in the Falzumfangsfläche 6, so that for the overlapping drive rod 16 and the coupling piece 22 a increased contact surface along the U-web 34 results. A reverse arrangement would cause the coupling piece 22 would have to engage in the space lying between the U-legs 31 and could rest exclusively on the U-leg 31 for support. In addition, the arrangement according to the embodiment allows the drive rod 18 may have a simple rectangular cross-section.

From the Fig. 4 is still seen that the drive rod 16 is guided in a housing 36 with a U-shaped cross-section. For this purpose, the housing 36 has a web 38 projecting from the base 37, which corresponding to the clearance 39 (FIG. Fig. 5 ) of the U-leg 31 is dimensioned. The U-legs 31 are supported on the base 37. On the U-legs 40 of the housing 36, which extend from the groove bottom 32, starting perpendicular to the sash or to the wing peripheral surface 6 inside facing each other webs 41 are provided, which the clearance of the U-legs 40th reduce so far that the drive rod 16 also a - based on the illustration after Fig. 4 vertical - leadership receives. At the same time, the coupling piece 22 can be supported on the webs 41, so that in the Fig. 4 downward force component does not lead to a jamming of the drive rod 16 in the housing 36.

Since at the same time the free U-legs 40 of the housing 36 occupy a slightly greater distance from each other than the width 42 of the drive rod 16, these form a guide for the drive rod 16, so that the drive rod 16 also gets a lateral support. The drive rod 18 also receives a lateral guide, with the advantage that the drive rods 16, 18 and the flange 43 of the coupling piece 22 are designed so that they have only a small lateral play in the housing 36. By the housing 36 thereby creates a from above - perpendicular to the Flügelfalzfläche 6 more accessible - channel, which allows a simple joining of the coupling element pairing 15.

From the Fig. 7 the construction of the coupling element pairing 15 with the omission of the housing 36 can be seen. The fully extended drive rod 18 of the fitting assembly 8 shows a first maximum coupling position, while the dotted executed drive rod 18 shows a second position. Within the coupling region determined by the length 45 of the oblong hole 27, the coupling piece 22 can be mounted so that an adjustment range or application tolerance range 46 of the coupling element pairing 15 results. Within this application tolerance range 46, sash rebate heights 4a of the fitting assemblies 8 and 10 can be covered without machining one of the fitting assemblies 8, 10.

This is essentially achieved in that the overlap region 47, in which the drive rod 18 can cover the drive rod 16, is maximized compared to the conventional coupling device. A cutting of one of the two drive rods 16 or 18 is thereby unnecessary, since the two drive rods 16, 18 can completely cover each other in the first smallest wing size - ie the smallest dashed sash height shown). In the second conceivable maximum position, the drive rods 16, 18 overlap substantially only with the short-coupling element 22 which determines the form-fitting engagement length 48 desired application tolerance range 46 can not be achieved, then a correspondingly larger-sized fitting assembly 8 is provided.

It thus follows quite inevitably that the fitting assembly 8 are manufactured in different gradations, which differ in their length corresponding to the application tolerance range 46 of the fitting assembly 10.

In the embodiments according to Fig. 2 and 3 the fitting assembly 10 is formed in each case as a corner 12. This is necessary and useful if a locking of the window or the door on an adjacent wing leg (eg along the profile spar 2c in Fig. 1 ) is to be achieved. In this case, a deflecting member 50 is connected to the drive rod 16, as in the Fig. 2 and 7 indicated. The deflection member 50 is guided in the angular housing 36 and in turn is another - along the profile spar 2c displaceable drive rod 52 ( Fig. 1 ), which in the exemplary embodiment belongs to a display device 53. The opening device 53 can be coupled via a coupling element 54. As a result, a thrust movement of the drive rod 16 is transmitted to the also slidably guided in the housing 36 drive rod 52 of the Ausstellvorrichtung 53, which is coupled to the drive rod 52 via a pin-hole coupling. It is also conceivable that, instead of the pin-hole coupling of the drive rod 51, a coupling element pairing corresponding to the pair of coupling elements 15 is provided, for example in order to take account of different blade rebate widths 4b.

In contrast, the fitting assembly 9 is a closer which has the bolt 11 perpendicular to an adjacent sash (here the sash member 2d.) This is a particularly simple embodiment of the espagnolette 5, for example with a rotary sash, since the baffles 50 can be dispensed with.

It is also provided that the drive rod of the closer is held on the wing corner by a housing corresponding to the housing 36.

To cover the drive rods 16, 18 and possibly further provided drive rods (eg, 51 and 52) of the drive rod fitting 5, the drive member 8 with a Faceplate 60 provided. The faceplate 60 is associated with the drive member 8 so that it is flush with the Flügelfalzfläche 6 in the installed state of the casement 2.

From the Fig. 2 and 3 It can be seen that the housing 36 is provided in the corner portion 61 with a cover 62. The cover 62 is angular and engages over both the leg 13 as well as the leg 14 in a partial area and covers the region lying between the U-legs 40 from. On the one hand, the cover 62 helps to stabilize the housing 36 in that the U-legs 40 receive an additional connection. On the other hand, the deflecting member 50 is guided displaceably in the corner region 61. Therefore, the cover 62 also forms the guide for the deflector 50.

Finally, the cover 62 also forms a guide 63 for a rail 64, as shown in the illustration Fig. 8 recognizable. For this purpose, the cover 62 has an opening 65 which extends along the sash rebate 6 and forms the guide 63 for the rail 64. The rail 64 is accommodated along the opening 65 in this verschiebar and in turn forms a cover 66 of the housing 36, which closes the space between the faceplate 60 and the cover 62. Thus, the rail 64 covers the coupling connection 17 within the housing 36. The otherwise otherwise necessary attachment of an additional face-plate to the housing 36 is eliminated.

Like in the Fig. 8 indicated on the fitting groove 33 indicated there, the opening 65 and thus also the rail 57 is mounted in a widened relative to the housing 36 portion of the cover 62, which is assigned in the mounted state of a stage of the fitting groove 33. In this case, the opening 65 is at the height of the free ends 68 of the U-legs 40 of the housing 36th

Evidently the FIGS. 8 and 9 the opening 65 and the rail 64 is provided with a tuned T-shaped cross-section. This maximizes the stability of the rail 64 despite the limited space in the fitting groove 33. In the original state, the rail 64 is designed so that it can cover almost the entire leg 13. If there is a greater overlap of the drive rods 16 and 18 due to the Flügelfalzhöhe 4a and the dimension of the drive member 8, then the rail 64 by moving in the opening 65 are adapted to abut the faceplate 60. Evidently the Fig. 3 then is a section 68 on the cover 62 via. This section 62 of the rail 64 must be disconnected. For this purpose 64 markings 69 are mounted on the back of the rail. By means of the markings 69, the portion 62 to be separated can be identified and the rail 64 can be shortened, for example, by sawing or cutting by means of a punching or fitting shears.

It is ideal, however, if the cutting of the rail 64 is simplified by the fact that the markings 69 are formed as predetermined breaking points 70, as this no further tool is required. The markings 69 are designed as mutually parallel deep grooves 71 and the rail 64 is made of a material that promotes breakage. The fact that the notches 69 are mounted on the underside of the rail 64, a visual impairment of the fitting surface is avoided.

In order to secure the displacement position of the rail in the opening, it is provided that the rail 64 has an omega-shaped open-edged recess 73 on the end 72 facing the fitting assembly 8, which forms a coupling device with the face-plate 60. In order to securely hold the fitting assembly 8 in the fitting groove 33, it is provided that the face-plate rail 60 is provided with a bore 75 at the end 74 facing the fitting assembly 10 (FIG. Fig. 7 ). The bore 75 serves for the passage of a fastening screw, not shown here, which is anchored in the groove bottom 32 of the fitting groove 33. Thus, the fixing screw does not affect the thrust movement of the drive rods 16 and 18, the faceplate 60 extends beyond the drive rod 18 in a middle position of the drive member 8 in a design of the espagnolette fitting 5 as a turn-tilt fitting by more than half a stroke length of the drive rod 18. This allows the drive rod 18th - Starting from a middle position - each perform a half stroke in each direction without colliding with the mounting screw. The fastening screw passes through the bore 75 and the slot 27 in the drive rod 16th

In order to connect the rail 64 to the face-plate rail 60, the rail 64 engages under the face-plate rail 60 at least with an angled region 76 which has the recess 73. The recess 73 is dimensionally designed so that they Locking screw engages detent. Since the region 76 is located under the faceplate 60, the recess 73 is also covered after locking.

In order to provide the required elastic deformability is a production of the rail 64 as a molded plastic part of advantage, especially since thereby the predetermined breaking points 70 can be easily configured. The housing 36 can be manufactured inexpensively as a plastic molding.

In the Fig. 10 is on an enlarged scale the engagement of the fine teeth 26, 29 visible. The fine teeth 26 of the coupling piece 22 passes through the slot 27 in the drive rod 16 with the central web 80. On the longitudinal sides of the central web 80 is evidently the Fig. 6 the fine teeth 26 attached. The fine toothing 26 is provided in the joining direction 81 with joining bevels 82, by means of which coupling with the drive rod 16 is facilitated.

The fine teeth 26, 29 consist of intermeshing mushroom-shaped teeth 83, 84. These engage behind each other in a longitudinal direction 85 of the drive rod 16 and in a transverse thereto - in the Fig. 10 lying in the plane of the drawing - second level. The positive connection in this second parallel to the web 34 of the drive rod 16 extending plane causes the slot 27 is not widened along the double arrow 85 even with larger forces to be transmitted. In a conventional toothing Aushebekräfte arise, which would lead to a deflection of the teeth 29. The crowned tooth ends 86, 87 engage behind a respectively adjacent pair of teeth 88, 89 on its tapered tooth root 90, 91.

The production of the drive rod 16 from a thin sheet metal allows the filigree shape of the fine toothing 29th

Window or door comprising wings (2) and frames (3) and comprising an espagnolette fitting (5) in which (window or door) this espagnolette fitting (5) is composed of at least two fitting units (8, 9, 10) that couple together in a moveable fashion, wherein the effective overall length of the fitting units (8, 9, 10) can be adjusted to different length dimensions of the wing dimensions (4a, 4b) of the window or door by way of coupling element pairs (15) that can be adjustably engaged with one another in fine steps in mutually overlapping form-locking fashion, wherein such coupling element pairs (15) are provided at least between the facing ends of the espagnolettes (16, 18) of the adjacent fitting units (8, 9, 10), and wherein each of the coupling element pairs (15) is formed by a short coupling element (26) at one espagnolette (18), said short coupling element determining an effective or pre-determined form-locked engagement length (48) and a long coupling element (29) at the other espagnolette (16) tailored according to a possible adjustment length in the adjustment range or application tolerance range (46),
   characterised in that the coupling element (29) and/or the associated espagnolette (16) is over-gripped or under-gripped by the espagnolette (18) that comprises the short coupling element (26) determining the form-lock engagement length (48) along the entire application tolerance range (46) at a minimal length dimension within the application tolerance range (46) so that the coupling element (29) remains effective along its entire length (45).
2. Window or door according to claim 1,
   characterised in
   that the espagnolette (16) has a U-shaped cross-section.
3. Window or door according to claim 2,
   characterised in
   that the free U-legs (31) of the U-shaped cross-section point away from the espagnolette (18).
4. Window or door according to one of the claims 1 to 3,
   characterised in
   that the coupling element is formed by a fine toothing (29) that is attached to the espagnolette (16) at the longitudinal side edges (28) of an elongated hole (27).
5. Window or door according to claim 4,
   characterised in
   that the longitudinal side edges (28) of the elongated hole (27) run in alignment with the U-legs (31) of the espagnolette (16).
6. Window or door according to claim 5,
   characterised in
   that the fine toothing (29) is moulded to the insides (30) of the U-legs (31) of the espagnolette (16).
7. Window or door according to one of the claims 6,
   characterised in
   that the fine toothings (26, 29) consist of meshing mushroom-shaped teeth (29', 29") so that the fine toothings (26, 29) act in a form-locking fashion in two planes.
8. Window or door according to one of the claims 1 or 7,
   characterised in
   that the espagnolette (16) is allocated to a fitting unit (10) which has a housing (36), wherein the housing (36) has an essentially U-shaped cross-section.
9. Window or door according to claim 8,
   characterised in
   that the free U-legs (40) of the housing (36) run vertically to the wing rebate surface (6) and that the U-legs (40) form a guide for the espagnolette (16).
10. Window or door according to claim 7 or 9,
    characterised in
    that the bar (38) which connects the U-legs (40) of the housing (36) is allocated to the groove base (32) of the fitting groove (33).
11. Window or door according to claim 8 or 10,
    characterised in
    that, at the housing (36), in the corner area (61), a cover (62) is provided at the housing (36) which covers the area located between the U-legs.
12. Window or door according to claim 11,
    characterised in
    that the cover (62) has an opening (65) that extends along the rebate peripheral surface (6), said opening forming a guide (63) for a track (64) that, along the opening (65), displaceably forms a cover of the housing (36).
13. Window or door according to claim 12,
    characterised in
    that the opening (65) is attached at the level of the free ends (67) of the U-legs (40) of the housing (36).
14. Window or door according to claim 12 or 13,
    characterised in
    that the opening (65) and the track (64) have matching T-shaped cross-sections.
15. Window or door according to one of the claims 12 or 14,
    characterised in
    that the track (64) is provided with markings (69) that enable a length reduction and that the markings (69) are designed as predetermined break points (70).
16. Window or door according to claim 12 to 15,
    characterised in
    that the fitting unit (8) has a fore-end track (60) covering the espagnolette (18), said fore-end track having a bore (75) near the end (74) that faces the second fitting unit (10), wherein the fore-end track (60) rises above the espagnolette (18) in a central position of the espagnolette (18) by more than half the stroke length of the espagnolette (18) and wherein a fastener goes through the bore (75) and the elongated hole (27) in the espagnolette (16).
