Description

The invention relates to a fitting for windows or doors according to the preamble of claim 1.

One such EP 1 121 501 B1 known fitting has a stop body which can be fixed to a window or on a door, and a handle in the form of a handle which is axially fixed-rotatably mounted on the stop body. A torsionally connected with the handle square pin passes through the stopper body and is used to operate a locking mechanism. Between the handle and the square pin, a coupling arrangement is provided with which a torque transmission from the handle to the square pin effected, however, is blocked by the square pin to the handle. This allows the window or door to be opened from the inside via the handle at any time. Conversely, however, a movement exerted on the square spindle, for example, via the window or door mechanism is blocked, so that the handle coupled to the square spindle remains stationary in the event of a manipulation. Such a fitting contributes to the protection against burglaries.

The in EP 1 121 501 B1 revealed fitting is constructed relatively complex with numerous components and components, which leads to high assembly costs and leads to high production costs. He also encountered not the problem that windows and doors have different frame or profile strengths, so that the distances between the stop surface for the stop body of the fitting and the integrated mechanism in the window or in the door are specified differently. Consequently, - depending on the design of the window or door - fittings with different length square pins needed. However, because the length of the protruding over the stop body square section is fixed rigidly, a matching square pin must be used from the factory or on site to ensure reliable operation of the mechanism through the fitting can. This requires a high logistic effort for the manufacturer as well as for the customer, because a large number of square pins with different lengths have to be stored. Moreover, there is a risk that in the end the wrong pen is selected, which may affect the functionality of the fitting or the window or the door.

The aim of the invention is to overcome these and other disadvantages of the prior art and to provide a window or door fitting that is inexpensive and easy to handle with simple means. He should automatically take into account the different frame or profile strengths especially when attached to a window or on a door and - while maintaining its safety or protective function - to ensure an always reliable coupling to the built-in window or door mechanism.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 15.

In a window or door fitting for actuating a mechanism integrated in the window or in the door, with a stopper body which can be fastened to the window or the door, with a handle which is axially fixed rotatably mounted on or in the stop body, with a polygon for mechanical coupling of the fitting to the integrated in the window or in the door mechanism, the polygon with a Polygonal section protrudes beyond the stopper body, and formed with a formed between the handle and the polygonal coupling arrangement with a torque transmission from the handle to the polygon effected, however, is locked from the polygon to the handle, the invention provides that the length of the over the stopper body protruding and insertable into the window or door frame polygonal section is automatically adjustable when attaching the stopper body to the window or on the door, the polygon is longitudinally displaceable and rotatably guided in the coupling assembly and extending through this into the handle.

The longitudinally displaceable and non-rotatably guided in the coupling arrangement polygonal thus adapts automatically when mounting the fitting to the respective predetermined frame or profile thickness of the window or door without polygonal pins must be present with different lengths that are appropriately selected and used accordingly have to. The handling of the fitting is thus significantly simplified. The storage of a variety of different square lengths is no longer required. Moreover, it is ensured that the polygon always accurately fits into the window or door mechanism, so that the window or door can be reliably operated. Operational safety is significantly increased. Errors during assembly, especially by the fitter on site, are effectively avoided. At the same time, the coupling arrangement formed between the handle and the polygon offers protection against unauthorized access from the outside, because its function is completely retained.

The polygon is slidably guided within the coupling assembly by a limited movement stroke along the axis of rotation of the handle and movable longitudinally displaceable against a spring force. A spring preferably pushes the polygon permanently outward, so that it can engage safely and reliably in the window or door mechanism. At the same time, the spring yields if the pin should be too long and is pushed back into the handle during assembly through the coupling arrangement. It is expedient if the polygon is supported by a compression spring within the handle.

Thus, the spring-loaded polygon can not fall out of the coupling assembly or from the stopper body, the movement of the polygon is limited within the coupling assembly of at least one stop. The polygon thus finds appropriate support within the coupling arrangement. He can not be lost.

In order to achieve an optimum adjustment of the respectively required length of the protruding from the stopper polygonal section, the polygon has at least one other stop, which determines the penetration depth of the polygon into the integrated in the window or in the door mechanism. As a result, the end portion of the polygon, for example, always fully engage in a gearbox, but without this end to penetrate and abut the window profile. Collisions with the frame or the profile of the window or the door are thus effectively avoided.

A further important embodiment of the invention provides that the coupling arrangement comprises two entrainment between the handle and the polygon, the force-and / or form-fitting coupled under predetermined Drehwinkelspiel between driver surfaces with each other, that an associated with the operation of the handle movement the polygon is transferable. In this case, a first driver is provided, which is rotatably connected to the handle, while a second driver rotatably receives the polygon and longitudinally displaceable.

In order to prevent unauthorized actuation of the handle or the window or door mechanism from the outside via the polygon, the coupling arrangement has at least one between the drivers and the stopper body existing locking member, which is designed and / or arranged such that one on the handle acting torque on the polygon is transferable. However, that a torque acting on the polygon stops or blocks a multi-edge movement or an operation of the mechanism integrated in the window or in the door. For this purpose, a frictional, positive and / or frictional connection can be generated between each locking member and the second driver, wherein each locking member can be displaced and / or actuated by means of functional surfaces or flanks formed on the drivers.

The invention further provides that each locking member is spring-loaded and designed as a cylinder body or ball, wherein within the stopper body to the locking members corresponding locking recesses are provided.

With such a coupling arrangement, the fitting acts like a mechanical diode. ie an operation of the window or door mechanism on the handle is possible at any time, while an unauthorized adjusting movement is prevented directly on the polygon of the locking members, because these force, form or frictionally in a rotation of the second, torsionally connected to the polygon driver the locking recesses in Stop bodies are pressed. The rotation angle clearance provided between the drivers is important here. It ensures that upon rotation of the handle, the locking members of the functional surfaces or flanks of the first, rigidly connected to the handle driver are lifted out of the locking recesses in the stopper body and the driver surfaces of the driver engage before the functional surfaces or flanks of the second, torsionally rigid connected to the polygon driver can press the locking members into the locking recesses. Conversely, it is ensured that upon actuation of the polygon and thus rotatably connected second driver, the locking members are pressed into the locking recesses before the first driver can lift them out. The fitting thus offers a high degree of security in a simple manner. Additional lock cylinders or other locking elements are not necessary.

Each locking member are preferably associated with at least two locking recesses, so that the blocking effect of the coupling arrangement can be effective if necessary in different angular positions of the handle. Appropriately, the locking recesses are therefore arranged at uniform angular intervals in the stopper body.

Another important embodiment of the invention provides that the locking recesses are formed in an insert body which is non-positively and / or positively inserted into the stop body. The insert body further accommodates the coupling arrangement in the manner of a housing. He has to have a recess in which the drivers are rotatably mounted concentrically to the axis of rotation of the handle. The insert body thus forms not only a pivot bearing for the driver and an abutment for the locking members. It also secures the drivers and the locking members and thus the entire Koppelanordndung in the stop body, so that an overall simple and compact design results, which can be produced quickly and inexpensively and easy to handle.

In order for the handle to always reliably and precisely reach its functional positions predetermined by the window or door, the first driver can be latched by latching means in at least one excellent functional position of the handle and / or the mechanism integrated in the window or in the door. The locking means are formed on the stop body. They engage in reaching the at least one excellent functional position in corresponding locking recesses in the first driver.

Structurally, it is advantageous if the locking means are integral with the stop body. Assembly and assembly are significantly simplified. This also helps if the Locking members and the locking means along the axis of rotation of the handle or the polygon are arranged in different planes. This allows in particular a modified, in particular material-saving component design of the driver elements, which also contributes to the cost reduction. At the same time, a high degree of stability is achieved, so that the fitting can easily withstand even heavier loads.

The in Fig. 1 generally designated 1 fitting is designed as a window fitting. He has a handle 6, which is mounted with a handle neck 7 axialfest-rotatably mounted on a stopper body 4. For actuating a mechanism integrated in the window (not shown), a polygon 8 is provided, which is preferably designed as a square pin. This protrudes with a polygonal section 8a on the stopper body 4 also to intervene positively with its free end 8d in the window mechanism, in particular in a provided therein (also not shown) gearbox. A formed between the handle 6 and the polygonal 8 coupling assembly 10 is formed such that a torque transmission from the handle 6 for polygonal 8 effected, however, from the polygon 8 to the handle 6 is lockable. This effectively prevents unauthorized opening of the window by actuating the polygon or the window mechanism.

The stopper body 4 is formed as a rosette, which is fastened by means of screws 16 to a (not shown) casement. One between the handle neck 7 and the Rosette body 4 pivotally arranged cover 14 can be raised against a compression spring 20 against the handle neck bottom. It covers in the assembled state of the fitting 1, the rosette body 4 and the screws 16 to the outside. For rotational mounting of the cover 14, a cylindrical neck portion 22 is integrally formed on the rosette body 4 centrally above a passage opening 24 (see FIG Fig. 2 ), which engages with a small movement play in a central recess 13 of the cover 14. The compression spring 20 surrounds the neck portion 22 and holds the edge 14 can be locked with the rosette body 4 cover 14 in position.

To accommodate the screws 16 24 two screw holes 26 are symmetrically to both sides of the through hole 24 are introduced in the rosette body, which - like Fig. 3 shows - end in pin 15 at the back. These protrude into a recess 21, which is introduced into the back of the rosette body 4 and serves for frictional and positive reception of an insert body 50.

The insert body 50 has coaxially to the screw holes 26 and to the pin 15 in the rosette body 4 at the edge two recesses 58 which receive the pin 15 of the rosette body 4 positively. A through hole 51 in the insert body 50 is concentric with the central through hole 24 of the rosette body 4 and thus also concentric with the axis of rotation D of the handle 6. The opening 51 extends within the insert body 50 to a circular recess 151, the - Fig. 2 shows - is circumferentially provided with a plurality of radial segment-shaped recesses 52. The recess 151 serves to receive the coupling arrangement 10 formed between the handle 6 and the square 8, in particular as a pivot bearing of two drivers 28, 42 of the double arrangement 10. The recesses 52 are arranged symmetrically on both sides of the passage opening 51 and at equidistant angular intervals. On the back of the insert body 50 integrally formed pins 56 continue the screw holes 26 of the rosette body 4 for the screws 16 and align the rosette body 4 during assembly of the fitting 1 on the window frame, which is provided with corresponding holes from.

One recognizes in Fig. 1 in that the insert body 50 forms a lower termination for the rosette body 4. Accordingly, the insert body closes with its underside up to the pin 56 flush with the bottom of the rosette body 4. In order to fix the insert body 50, latching projections 104 are provided within the recess 21 of the rosette body 4, which engage behind the insert body 50 in a force-locking and / or form-locking corresponding latching edges 55. In Fig. 4 shown dismantling recesses 57 on the edge of the recess 21 are used for approach of a tool to the insert body 50 if necessary to be able to detach from the rosette body 4.

As Fig. 4 Furthermore, in the rosette body 4, which is preferably made of plastic, recesses 124 are provided on the edge side between webs 114. These lead to a ribbing of the rosette body 4, which saves material and at the same time has a stiffening effect.

To ensure that the square pin 8 regardless of the frame thickness of the window profile with its free end 8 d always completely engages the gearbox of the window mechanism, the length L of the projecting beyond the stopper body 4 and insertable into the window frame polygonal section 8 a when attaching the stopper body 4 on Window automatically adjustable. For this purpose, the square pin 8 against a spring force longitudinally displaceable and rotatably guided in the coupling assembly 10 and slidably mounted for a limited movement stroke BH along the axis of rotation D of the handle 6 and adjustable. The force acting on the square pin 8 spring force is generated by a coil spring 18 which is inserted in a blind hole 5 in the handle neck 7. The slidably guided in the coupling assembly 10 square pin 8 is thereby permanently loaded along the axis D in the direction of the window or in the direction of closing mechanism. It projects through the coupling arrangement 10 and extends in the opposite direction into the blind hole 5 of the handle 6.

Thus, the square pin 8 can not fall out of the handle 6 or from the coupling assembly 10, whose movement stroke BH is limited in the direction of the window by a stop 8b. This is preferably formed on the square pin 8, for example in the form of a simple notch, which is pressed or stamped into a longitudinal edge of the pin 8. But you can also attach a pin or a pin laterally or diagonally to the square pin 8, for example by welding or soldering. It is important that the stop 8b between the coupling assembly 10 and the handle 6 is located so that the spring 18 can push the longitudinally displaceably mounted square pin 8 outward until the stop abuts 8b on the coupling assembly 10. Inwardly, the movement stroke BH of the square pin 8 is limited by the depth of the blind hole 5 and by the size of the spring 18.

The free end 8d of the square pin 8 carries a further stop 8c. which can also be designed in the form of a notch or stamping. This stop 8c is aligned such that the square pin 8 can penetrate sufficiently deep into the gearbox of the window mechanism, but this does not penetrate so far that it abuts on the other side of the window profile. The further stop 8c therefore predetermines the penetration depth for the polygonal section 8a projecting beyond the rosette body 4. It also ensures that each square 8 engages always with the same length in the gearbox, so that a constantly optimal power transmission is guaranteed.

At the same time causes the stop 8c together with the spring 18 in the handle neck 7, an automatic adjustment of the length L of the protruding over the rosette body 4 square section 8a. Should the square pin 8 be too long for the existing window profile, the square section 8a first penetrates with its free end 8d into the gearbox until the stop 8c abuts against it. Anschießend the square pin 8 against the spring 18 in the handle neck 7 of the handle 6 pushed back until the rosette body 4 comes to rest on the window.

The total length of the square pin 8 and its movement stroke BH are coordinated so that the fitting 1 can be mounted on a variety of windows with different frame thickness. An exchange of the square pin 8 against a longer or a shorter square pin is therefore not necessary. Likewise, no pins have to be stored with different lengths or made available to the fitter, which significantly reduces the logistics and assembly costs.

In addition to the automatic adjustment of the length L of the square pin 8 to different frame or door leaf thicknesses, the coupling arrangement 10 between the handle 6 and the square pin 8 ensures increased burglary security, because this is designed such that the window or the mechanism integrated therein only can be actuated from the inside via the handle 6 and not from the outside via the square pin 8. For this purpose, the polygon 8 is longitudinally displaceable and rotationally fixed in the coupling assembly 10, which has two drivers 28, 42. In addition, 4 locking members 38 are arranged between the drivers 28, 42 and the rosette body. These effect, together with the coupling members 28, 42, that a force acting on the handle 6 torque on the polygon 8 is transferable, but that acting on the polygon 8 torque a polygonal movement or an actuation of the in the window or in the door integrated mechanism stops or locks.

The first driver 28 forms a handle driver. It is sleeve-shaped and rotatably connected to the handle 6. He has a central through hole 281 and a flange portion 282, which is inserted with little play in a circular recess 121 in the rosette body 4 (see Fig. 3 ). The flange section 282 is adjoined by a shaft 283 of smaller diameter, which encloses a neck projection 9 of the handle 6 through the passage opening 24 and the neck section 22 of the rosette body 4. The neck extension 9 is seated centrally to the axis of rotation D on the underside of the handle neck 7 and forms the end access to the blind hole 5 of the handle. 6

The outer circumference of the neck projection 9 does not form a cylindrical surface, but corresponding to the inner surface of the sleeve shaft 283 or to the inner wall of the through hole 281 a polygonal surface, so that the patch on the neck 9 sleeve 28 is rotatably connected to the handle 6. The axial fixing of the sleeve 28 on the handle 6 is carried out by a flanging BR by the outer edge of the neck projection 9 is formed within the sleeve 28 to the outside. The passage opening 281 in the sleeve 28 is provided on the inner circumference with a shoulder or a step 284.

Around the neck lug 9, an annular recess 71 is formed in the handle neck 7. This accommodates both the neck portion 22 of the rosette body 4 and the compression spring 20, so that both are not visible from the outside and the bottom of the handle neck 7 is only a short distance above the cover plate 14.

In the outer periphery of the flange portion 282 a total of four locking recesses 134 are introduced for locking means 34 at angular intervals of 90 °. The latter are formed in the rosette body 4 on spring webs 234 which lie symmetrically on both sides of the recess 121 for the flange portion 282. By the two locking means 34, which are preferably integral with the spring bars 234 and the rosette body 4, the window handle 6 is locked in four excellent functional positions, preferably in the closed position, the open position (right or left) and the tilted position of the window, wherein each functional position both locking means 34 simultaneously engage in two mutually oppositely disposed locking recesses 134. The Griffmitnehmer 28 thus acts like a locking bush. The functional positions are thus always clearly visible to the user. Operating errors of the window are effectively avoided. Further locking positions are possible by further locking recesses 134 are introduced in the flange 282, for example, at angular intervals of 45 °. Again, the two locking means 34 engage in achieving an excellent functional position in two opposite latching recess 134 in the first driver 28, which positions the handle accordingly.
On the side opposite the shaft 283, the flange portion 282 carries four projections 285, which engage as coupling elements with the second driver 42 of the coupling arrangement 10. They are - like Fig. 4 shows - arranged symmetrically to the rotation axis D, wherein each two projections 285 are right and left to the longitudinal axis LA of the rosette body 4. They are also formed in cross-section L-shaped, which saves on a material and on the other hand ensures high stability and resilience.

The (unspecified) outer surface of the projections 285 is cylindrical corresponding to the flange portion 282, wherein the outer diameter of the flange portion 282 and the projections 285 corresponds to a small movement play the inner diameter of the recess 121 in the rosette body 4 and the recess 151 in the insert body 50. As a result, the handle driver 28 is precisely guided and rotatably mounted both in the recess 121 in the rosette body 4 and in the congruently lying recess 151 in the insert body 50.

As Fig. 4 Furthermore, the projections 285 have functional surfaces 128, 228 in the peripheral direction. The surfaces 128 of the projections 285 facing away from the longitudinal axis LA of the rosette body 4 form driver surfaces which engage with corresponding driver surfaces 142 of the second driver 42 under a predetermined angle of rotation clearance B. The longitudinal axis LA of the rosette body 4 facing surfaces 228, however, form functional surfaces or flanks, which cooperate with the locking members 38 of the coupling assembly 10.

The second driver 42 forms a Mehrkantmitnehmer. He has a disc-shaped base plate 421, which is laterally provided with two cutouts 422 to save material. Centrally supports the base plate 421 a neck portion 423, which is centrally provided with a square recess 424 for the positive and longitudinally displaceable recording of the square pin 8.

The base plate 421 also carries at the edge four projections 425, which are engaged as coupling elements with the Griffmitnehmer 28 of the coupling assembly 10. They are - like Fig. 4 shows - arranged symmetrically to the rotation axis D, wherein each two projections 425 are right and left to the longitudinal axis LA of the rosette body 4. she are also formed in cross-section L-shaped, which saves on a material and on the other hand ensures high stability and resilience.

The (unspecified) outer surface of the projections 425 is formed corresponding to the base plate 241 cylindrical, wherein the outer diameter of the base plate 241 and the projections 425 corresponds to a slight movement play the inner diameter of the recess 151 in the insert body 50. Thus, the Mehrkantmitnehmer 42 is precisely guided together with the handle driver 28 in the recess 151 in the insert body 50 and rotatably supported, while the flange portion 282 of Griffmitnehmers 28 is guided within the recess 121 of the rosette body 4 in a separate plane.

As well as the projections 285 of the handle driver 28 and the projections 425 of the Mehrkantmitnehmers 42 in the circumferential direction functional surfaces 142. These are the longitudinal axis LA of the rosette body 4 faces. They form driving surfaces which engage under predetermined angle of rotation clearance B with the driver surfaces 128 of the handle driver 28.

The base plate 421 carries four further projections 426, which are arranged in pairs on both sides of the longitudinal axis LA of the rosette body 4 approximately V-shaped. Between each projection pair 246, a receptacle 427 is formed parallel to the longitudinal axis LA, in which a spring 40 is inserted. The radially outwardly directed free ends of the projections 426 have on their longitudinal axis LA of the rosette body 4 facing inner edges 242 functional surfaces which cooperate with the locking members 38 of the coupling assembly 10. The surfaces or flanks 242 are at an acute angle obliquely to the longitudinal axis LA and thus form a kind of V-shaped funnel.

The arranged between the insert 50 of the rosette body 4 and the drivers 28, 42 locking members 38 are preferably formed as a cylinder body whose axes are parallel to the axis of rotation D of the handle 6. Its outer diameter corresponds to the inner diameter of the segment-shaped recesses 52 in the outer periphery of the recess 151 in the insert body 50, wherein the segment depth is smaller than the radius of the cylinder body. Thus, the cylinder body 38 engage positively in the recesses 52, but lie with their centers within the outer periphery of the recess 151 in the insert body 50th Wie Fig. 4 shows, each cylinder body 38 is spring loaded, wherein the recesses 427 lying in the springs 40 press the cylinder body 38 radially outwardly into the recesses 52 in. The neck portion 423 of the Mehrkantmitnehmers 42 forms the abutment for the springs 40, which are guided laterally by the projections 426. The locking members 38 may also be balls or other rolling elements, which engage positively in corresponding recesses 52 in the insert body 50.

On the side facing away from the projections 425, 426 side, the base plate 421 of the Mehrkantminehmers 42 carries a cylindrical shoulder 428 which continues the square recess 424 in the neck portion 423 and engages positively in the through hole 51 of the insert body 50. As a result, the driver 42 has an additional pivot bearing, which has a favorable effect on the stability of the coupling arrangement 10.

Fig. 4 shows the fitting 1 and thus the coupling assembly 10 in a starting position. For example, the handle 6 and thus the mechanism integrated in the window is in the closed position (6 o'clock position) in which the window is closed and locked. In the Fig. 4 non-visible latching projections 34 of the rosette body 4 engage frictionally and positively in two opposing detent recesses 134 of Griffmitnehmers 28, both of which are located centrally on the longitudinal axis LA of the rosette body 4. The locking members 38 of the coupling assembly 10 engage in the plane below the locking recesses 134 in Griffmitnehmer 28 frictionally and positively in two opposing recesses 52 in the insert body 50, which are also centered on the longitudinal axis LA of the rosette body 4. One recognizes in Fig. 4 in that in each case two further recesses 52 are formed on both sides of the longitudinal axis LA, for example at angular intervals of 30 ° each.

The projections 285 of the Griffmitnehmers 28 lie in the circumferential direction to the axis of rotation D between the projections 425 of the Mehrkantmitnehmers 42 on the one hand and the other projections 426 of the Mehrkantmitnehmers 42 and the locking members 38 on the other. In this case, the driver surfaces 128 of the handle driver 28 and the driver surfaces 142 of the Mehrkantmitnehmers 42, including the Drehwinkelspiel B face each other, while the functional edges 228, 242 of the drivers 28, 42 facing the locking members 38.

Turning the handle 6 from the closed position to the open position (in Fig. 4 to the left), then the Griffmitnehmer 28 also rotates to the left until two diametrically opposite functional edges 228 of the projections 285 of Griffmitnehmers 28 laterally abut against the locking members 38, but because each functional edge 228 against the outer periphery of the recess 151 is slightly inclined and because the (Unspecified) outer edges of the functional edges 228 off-center attack on the locking members 38, the latter are lifted against the force applied by the springs 40 spring force from the recesses 52 in the outer periphery of the insert 50 by the cylindrical locking members 38 slide over the edges of the recesses or over roll. After overcoming the Drehwinkeispiels B between the driver surfaces 128, 142 engage these non-positively and / or positively into one another, so that the Griffmitnehmer 28 now also the Mehrkantmitnehmer 42 rotates about the rotation axis D to the left. The square pin 8 is taken from the Mehrkantmitnehmer 42, whereby the rotational movement of the handle 6 is transmitted to the integrated mechanism in the window. The window can be opened (see Fig. 5 ).

Get the locking members 38 during the rotation in the other recesses 52 in the insert body 50, they are each - as previously described - lifted from the projections 285 and their functional edges 228 and pushed in the circumferential direction. As soon as the handle 6 has reached the open position, the latching projections 34 enter the latching depressions 134 in the handle driver 28, so that the handle 6 is exactly positioned.

On the other hand, if you turn the square pin 8, this movement is transmitted directly to the Mehrkantmitnehmer 42. Before the driver surfaces 128 of Griffmitnehmers 28 can couple to the Mitnehmerflächen 142 of Mehrkantmitnehmers 42 and before the functional edges 228 of the projections 285 engage with the locking members 38, and therefore before the Drehwinkelsspiel B is overcome, the locking members 38 of the sloping functional edges 242 the further projections 426 of the Mehrkantmitnehmers 42 radially outwardly into the recesses 52 in the insert body 50 pressed into it. The movement of the polygon 8 is thereby stopped by between the stopper body 4, the locking members 38 and the Mehrkantmitnehmer 42 a positive and frictional connection is generated. In this case, each locking member 38 is actuated by means of the multi-edge driver 42 formed functional surfaces 242 to the outside, so that the locking members 38, the recesses 52 can not leave (see Fig. 6 ).

Depending on the force, the cylindrical rollers (locking members) 38 are pressed with permanent deformation in the locking recesses 52 of the insert body 50. The fitting must therefore be replaced after a break-in attempt against a new one. Burglary attempts can therefore prove reliable with the help of the fitting according to the invention.

Each locking member 38 are assigned in each locking position, two opposing locking recesses 52, so that the coupling assembly 10 withstands even higher loads easily. By arranged in equidistant angular intervals recesses 52 in the insert body 50 ensures that the fitting 1 is secured against unauthorized access from the outside, even if the handle 6 is not exactly in one of its excellent functional positions, for example, when the handle 6 is in its closed position not completely reached in the 6 o'clock position.

The performing during the rotation of the handle 6 locking operations in the plane of the coupling assembly are accompanied by a corresponding noise, which is perceived by a user as clicking. This click signals the presence of the safety mechanism, which prevents the pivoting of the handle 6 from the outside via the square 8 or the window or door mechanism.

Another advantage of the fitting according to the invention is that the drivers 28, 42 of the coupling arrangement are material-saving and therefore inexpensive to produce due to their relatively simple geometry. The assembly is simplified compared to the prior art. The rosette body 4, the handle 6 and the Griffmitnehmer 28 on the one hand and the Mehrkantmitnehmer 42, the locking members 38, the associated springs 40 and the insert body 50 on the other hand can be pre-assembled as assemblies, which are then joined by inserting the insert body 50 in the rosette body 4 have to. This modified assembly technique allows a changed, material-saving component design and thus contributes to the cost reduction.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. It can be seen, however, that the invention relates to a fitting for a window or a door, with a stopper body 4 which can be fastened to the window or the door, and with an actuating handle 6 in the form of a handle, which is pivotally connected to the stopper body 4 , A polygon 8 serves for the mechanical coupling of the actuating handle 6 to a mechanism integrated in the window or in the door. An integrated in the stop body 4 coupling assembly 10 is used for mechanical coupling and decoupling between the actuating handle 6 and the polygonal 8, wherein provided in the coupling arrangement securing means 38, 40, 128, 228 configured and / or arranged such that one with the actuation the handle 6 associated movement is transmitted to the polygon 8, so that the polygon 8 moves with the actuating handle 6, however, one over the Window or door mechanism on the polygon 8 unauthorized exercised movement is immediately blocked, so that the coupled to the polygon 8 actuating handle 6 remains unmoved.

The invention further provides further, that the length of the projecting beyond the stopper body 4 and insertable into the window or door frame polygonal section 8a is automatically adjustable in the attachment of the fitting 1 to the window or on the door, wherein the polygon 8 through extends the coupling assembly 10 through into the actuating handle 6, wherein the polygon 8 is guided within the coupling assembly 10 by a movement stroke BH slidably in the direction of its longitudinal axis. A first stop 8b and at least one further stop 8c define and limit the movement stroke BH of the polygonal pin 8 with respect to the coupling arrangement 10, a spring 18 being arranged between the polygonal 8 and the actuating handle 6, which holds the polygon 8 in the attachment of the window or door fitting axially positioned on the window or on the door.

It will be appreciated that a window or door fitting 1 for actuating a mechanism incorporated in the window or in the door has a stopper body 4 attachable to the window or door and a handle 6 axially fixedly rotatable on or in the housing Stop body 4 is mounted. A polygon 8 serves for the mechanical coupling of the fitting 1 to the mechanism integrated in the window or in the door, wherein the polygon 8 projects beyond the stop body 4 with a polygonal section 8a. With a formed between the handle 6 and the polygonal 8 coupling assembly 10 is a torque transmission from the handle 6 for polygon 8 effected, however, the polygonal 8 to the handle 6 lockable. To order when attaching to a window or on a door different frame or to consider profile thicknesses automatically, it is provided that the length L of the projecting beyond the stopper body 4 and insertable into the window or door frame polygonal section 8a is automatically adjustable when attaching the stopper body 4 to the window or on the door, the polygonal 8th is longitudinally displaceable and rotatably guided in the coupling assembly 10 and extends through this into the handle 6 into it.
