description

The invention relates to a fitting arrangement for a window, a door or the like, with a mandrel for torque transmission of the rotational movement of a control handle on a fitting component.

In known fitting arrangements for windows, doors or the like, a rosette attached to the sash frame of the window, the door or the like is provided on which an operating handle is rotatably mounted. The operating handle has a square recess into which a trained as a square bar mandrel is inserted with one end, which engages with its other end in a square hole of a fitting component for transmitting torque. The fitting component may for example be a gear of a drive rod transmission. A rotation of the operating handle leads via the mandrel to the corresponding rotation of the fitting component and thereby drives, for example, a drive rod to unlock the window, the door or the like, rotate open or tilt open or lock, etc.

The invention has for its object to provide a different design of a fitting arrangement.

This object is achieved in that the mandrel has a circular cross-section which is provided with at least one cooperating at least with the fitting component groove-like driving recess, which extends in the longitudinal direction of extension of the dome. As a result, a square-shaped mandrel is used instead of a square-shaped mandrel for torque transmission. In order for the dome according to the invention to have a torque can perform ment transmission, it has at least one groove-like depression which extends in the longitudinal direction of the dome and which cooperates with the fitting component to which the torque is to be transmitted. It is therefore possible to insert the mandrel according to the invention into corresponding receptacles of operating handle and / or fitting component and thereby to produce a rotary coupling via the driving recess. If large torques are to be transmitted, it is possible to provide several, distributed over the circumference of the cross-section arranged Mitnehm- wells that may be the same or different in their profile. About the angular distribution of the driving recesses and / or on the profile structure of the driving recesses a rotational position assignment can be realized, that is, such a mandrel can be inserted, for example, only in a rotational position in the associated operating handle and / or the associated fitting component. Of course, it is also possible that a plurality of angular positions can be realized, but not - as in a known square bar - inevitably offset by 90 ⁰ C to each other, but have corresponding predeterminable angle.

According to a development of the invention, a wing frame of the window, the door or the like assignable guide, in particular socket, is provided which has a circular cross-section bearing bore in which the mandrel is rotatably mounted. This measure is to be regarded as an important feature, since the guide which can be arranged on the casement supports the mandrel radially. This is rotatably supported and guided due to its circular cross-section in the circular bearing bore of the guide, so that even over years always a precise and easy run of the control handle is guaranteed. Canting or knocked-out and wobbly connections are therefore avoided.

According to a development of the invention, the guide for attachment to the casement is provided with fixing means. The fixing means hold the guide stably on the casement, so that the control handle mounted on the guide receives a stable assignment to the casement.

An important further development of the invention provides a fitting element which can be assigned to the casement of the window, the door or the like and which has at least one bearing recess which is circular in cross-section and in which the mandrel is rotatably mounted. This also leads to a stable pivot bearing of the dome. Is the embodiment made such that the mandrel is rotatably mounted both in the guide and in the fitting element, so there is a double bearing for the mandrel, whereby particularly good, smooth and stable properties are achieved.

The bearing recess may preferably be a bearing opening or a bearing blind hole. When the bearing breaks through, the mandrel, with its circular cross-section, penetrates the bearing opening, which is circular in cross-section. In the case of a storage bag hole, the corresponding end region of the circular cross-section engages in the storage bag hole which is circular in cross-section.

A development of the invention provides that the bearing bore axially spaced / adjacent to the bearing recess. The axial direction is defined by the longitudinal direction of the dome. As a result, the two bearing points of the dome are axial spaced or axially adjacent to each other, so that a correspondingly good leadership of the cathedral is guaranteed.

It is advantageous if the fitting element has a housing which is provided with the bearing recess. The mandrel is therefore rotatably guided on the one hand in the guide and on the other hand in the housing of the fitting element. Advantageously, the housing is designed in several parts, so that a simple mounting of the housing or the fitting element on the drive rod is possible. Particularly preferably, the housing has two housing parts, so it is formed in two parts. The two housing parts expediently surround the drive rod in regions, with the drive rod preferably being received in each case proportionally by a housing part. The housing parts are preferably assembled or mounted perpendicular to the longitudinal extent of the drive rod. A complete passage of the drive rod through the housing to achieve a desired position is thus eliminated.

Particularly preferably, the housing parts are formed identically, whereby in particular the manufacturing costs of the advantageous fitting arrangement are reduced. In addition, with an identical design of the housing parts, which then represent turning shells, a wrong assembly excluded.

The fitting element can be designed in particular as a fitting gear. The fitting gear serves to implement the rotational movement applied to the control handle in a longitudinal sliding movement of at least one drive rod or the like. It is advantageous if the fitting component is a gear toothed wheel, in particular for driving at least one drive rod. The transmission gear is non-rotatably mounted on the mandrel, so that a rotational movement transmitted by the operating handle leads to the rotation of the transmission gear, with the result that this in particular drives the mentioned drive rod. This is achieved in that the teeth of the transmission gear engage in corresponding openings or recesses of the drive rod, whereby the rotational movement is converted into a linear movement.

The transmission gear may be formed in a simple manner as sheet metal stamping, that is, it has no collar or the like, but has everywhere the same thickness. It is rotatably mounted on the mandrel on the guide and / or the fitting element.

A preferred embodiment of the invention provides that the operating handle has a receiving recess in which an end region of the dome is inserted for the rotationally fixed receptacle.

By suitable means of the mandrel is held axially immovable on the control handle. Accordingly, if the mandrel is inserted at the desired depth into the attached operating handle and the operating handle is held axially immovable in this position, then it has a desired axial position. For example, in this position there is only a very small distance to the casement and / or to the bushing, that is, the operating grip is mounted substantially gap-free to the said components. Only a small movement gap, which is required for the rotation of the operating handle remains, and even with dimensional tolerances of the sash strength and / or different thicknesses of different sash designs, the Handle must always be positioned in the desired axial position without tools, only by plugging on.

Furthermore, it can be provided that the mandrel is held axially immovably on the fitting element and / or on the fitting component. Due to the axially immovable holding the mandrel is fixed in the corresponding axial position. This fixation in connection with the axial fixation of the operating handle leads to the fact that the operating handle on the casement occupies the desired axial position and also adheres, even if it is transmitted via it opening forces or the like. It is particularly preferred if the holding of the dome on the operating handle and / or on the fitting element and / or on the fitting component takes place by means of at least one detachable and / or non-detachable latching connection. The locking connection is simply effective when plugged on, so that a very simple assembly is guaranteed. A releasable locking seat of the locking connection has the advantage that - for example, for disassembly - a simple axial disassembly of the parts can be done. Optionally, it may further be provided that after a dismantling and a trouble re-engagement of the parts can be performed.

A further development of the invention provides that the operating handle has a fuse connected thereto, in particular a locking washer, which has a clamping bore into which the mandrel can be inserted in one direction and with respect to the other, opposite direction due to edge support / edge incision of the Edge of the clamping bore on / in the mandrel is fixed. The edge of the clamping bore, which may for example be formed by the ends of spring tongues, hold demzu- follow the mandrel or operating handle securely against the insertion force, so that no further axial attachment means must be provided. Rather, the assembly is made such that the operating handle is pushed as far as desired on the corresponding end of the dome. For example, an axial stop, in particular due to the guide, is present on the casement. Consequently, the operating handle is pushed onto the mandrel until it abuts against the axial stop and is thus positioned and axially fixed as well as non-rotatably. Even dimensional tolerances or wings of different thickness, which lead to a different width protruding the dome, do not require special features, special parts or mandrels of different lengths, because the control handle is pushed so far onto the mandrel until it has its desired position, which then by means of Locking washer is fixed axially with respect to a Wiederabziehens.

According to a development of the invention, it is provided that the mandrel in its lateral surface has a groove, in particular an annular groove, into which engages a securing element which is supported on the fitting element in the axial direction. The securing element can preferably be a spring, in particular a U-spring. The securing element is preferably made of spring wire. If the mandrel is inserted into the bearing recess of the fitting element, then the resilient securing element engages in the annular groove and therefore fixes the mandrel axially. By shifting the securing element, in particular by using its inherent elasticity due to its spring property, the groove can be released again, so that the mandrel - if desired - can be axially pulled out again. Advantageously, the groove - seen from the operating handle - arranged or formed behind the fitting component. This has the advantage that the mandrel, starting from the control handle to the fitting component to which the torque applied by the operating handle is to be transmitted, has no substantial cross-sectional taper, in particular in the form of a notch, so that high torsional forces from the operating handle on the mandrel the fitting component can be transferred. The arrangement of the groove beyond the fitting component - seen from the operating handle - thus has no effect on the transmittable torque or torsion. A torsional fracture of the dome under high loads is thus prevented by the advantageous embodiment.

The securing element is preferably in a particular open-edge receiving pocket of the fitting element. It is on the one hand -as already described- possible to first set the securing element on the fitting element and then insert the mandrel until the fuse element locked in the groove of the dome. Alternatively, however, it is also possible to proceed in such a way that the mandrel is initially inserted axially into the bearing recess so far that its groove has a desired axial position. Now, the securing element is introduced into the receiving pocket, whereby the axial securing of the dome is effected. In the latter case, it is not necessary for the securing element to be made of elastic material. If desired, however, an intrinsically elastic securing element can also be used in the latter case. Another embodiment of the invention provides at least one ramp on the spring and / or the receiving pocket for displacing, in particular spreading of the spring, whereby a release of the mandrel takes place. The spring is displaced or spread when pushed deeper into the receiving pocket. Alternatively, it is also possible to proceed such that the spring is not pressed deeper into the receiving pocket, but a piece is pulled out of the receiving pocket, whereby the mandrel is released.

The operating handle and / or the fitting component has at least one projection, in particular a rib, for engagement in the driving recess of the mandrel. As a result, a rotary coupling between control handle and mandrel or fitting component and mandrel is realized. If a plurality of driving recesses are provided on the circumference of the mandrel, a corresponding number of protrusions may be provided on the operating handle and / or on the fitting component. The projection preferably has a cross-sectional contour which corresponds to the cross-sectional contour of the driving recess in order to be able to transmit the largest possible torques and / or to bring about a connection which is as free of play as possible.

Furthermore, it is advantageous if the guide has at least one rotary position locking element which cooperates with at least one rotary position counter-locking element of the operating handle. The individual operating positions, such as locking position, Drehöffnungspo- position and Kippöffnungsposition etc. of the window, the door or the like are therefore predetermined due to the Drehstellungsrastelements in cooperation with the Drehstellungsgegenrastelement, that is, the user feels in these rotational positions certain persistence of the control handle. As a result, an exact operation is easily possible even for inexperienced people. If such a preferred position to be left, it must first be overcome by increased force required the corresponding rotational locking position.

Finally, it is advantageous if the mandrel has at least one second groove, in particular an annular groove, into which a securing element engages, wherein the first groove or annular groove of the dome, as seen in the insertion direction, has a chamfer which is aligned in the insertion direction. By the second engaging in a groove / annular groove securing element results in an increased axial retention of the dome on the fitting element. The chamfer on the - seen in the insertion - first groove / annular groove allows during assembly a simple penetration of the first securing element, which is also designed as a spring, in particular U-spring. Wherein the U-spring when inserting the dome first engages in the first groove / annular groove and then, due to the chamfer, is widened again, so that the mandrel can be further inserted.

Overall, the fitting arrangement according to the invention is characterized by a very simple and inexpensive construction. There are very few parts required. The installation is very simple and easy - even for inexperienced people - possible. Nevertheless, an exact control handle storage is realized, the high loadings easily withstands.

Figure 12 shows an embodiment of an advantageous housing of the fitting arrangement.

Figures 1 and 2 show in a perspective view of a fitting assembly 1 for a window, a door or the like. The fitting arrangement 1 has an operating handle 2, which is operatively connected to a drive rod 5 via a fitting element 4 designed as a fitting mechanism 3. The drive rod 5 is longitudinally displaceable by a plurality of drive rod guide elements 6, which are fastened to or in a window, a door or the like. For this purpose, the drive rod 5 a plurality of slots 7, in each of which a drive rod guide member 6 engages, wherein the slots 7 are aligned in its longitudinal extent parallel to the drive rod 5, so that the latter is longitudinally displaceable. The fitting element 4 has a housing 8, which is formed by two housing parts 9 and 10. In some cases, the housing 8 surrounds the drive rod 5. During a rotational movement of the operating handle 2, for example in the direction of the arrow 11, the drive rod 5 is linearly displaced by the fitting mechanism 3 in the direction of the arrow 12.

FIG. 3 shows, in a cross-sectional representation, the fitting arrangement 1 arranged on a casement 13. The casement 13 has an open-edged receiving pocket 14 in which the loading element 4 or the housing 8 rests. In this case, the depression 14 has in each case a shoulder 15, 16 on both sides in the direction of the longitudinal extent of the drive rod 5, on which standing area of the housing 8, or in each case a housing part 9, 10 rests. The drive rod 5 is mounted longitudinally displaceably in the housing 8 in the region of the shoulders 15, 16. The fitting element 4 has a bearing recess 18 formed as a bearing opening 17, which is formed in the housing part 9. The bearing recess 18 is aligned perpendicular to the longitudinal extension of the drive rod 5. Furthermore, the housing part 9, as shown in FIG. 4, has a recess 19 in which a fitting component 21 of the fitting mechanism 3 designed as a gearwheel tooth 20 rests, a rotation axis 22 of the gearwheel gear 20 being arranged coaxially with the bearing opening 17. The preferably designed as a sheet metal stamped gear transmission gear 20 has at its circumference 23 partially teeth 24 of a toothing, which engage in formed on the drive rod 5 recesses 25. Where the recesses 25 having area of the drive rod 5 seen in cross section to the transmission gear 20 is formed offset. Furthermore, the transmission gear 20 has an opening 26, which is aligned coaxially with the axis of rotation 22 and has a circular cross-section.

A mandrel 27, which has a circular cross section, is rotatably mounted about the axis of rotation 22 in the bearing recess 18 or the bearing opening 17 of the fitting element 4 / of the housing part 9, wherein it is pushed through the opening 26 of the gear wheel 20. As shown in the figure 4 in longitudinal section, the mandrel 27 along its longitudinal extent two groove-like driving recesses 28 and 29. The transmission gear 20 has corresponding projections 30, 31 which engage in the driving recesses 28, 29. Perpendicular to the receiving pocket 14, the casement 13 has a recess 32 in which a guide 33 is arranged, which has a circular bearing bore 34 in which the mandrel 27 is rotatably mounted. The mandrel 27 is thus rotatably mounted both in the guide 33 and in the fitting element 4, wherein the bearing bore 34 axially spaced from the bearing opening 17 is arranged. On the guide 33 of the operating handle 2 is arranged such that the mandrel 27 engages in a receiving recess 35 of the control handle 2. The receiving recess 35 also has two projections 36 corresponding to the projections 28 and 29 of the gearwheel 20, of which only one is shown in FIG. 3, which are designed as ribs 37 and engage in the driving recesses 28, 29 of the dome 27.

Upon a rotational movement of the operating handle 2 about the rotation axis 22, a torque is transmitted via the projections 36 / ribs 37 of the operating handle 2 on the mandrel 27, which is rotatably mounted in the guide 33 and in the fitting element 4, and of the mandrel 27 on the Driving recesses 28, 29 and the projections 30, 31 transmitted to the transmission gear 20, which drives the drive rod 5 through the engaging in the recesses 25 of the drive rod 5 teeth 24, the drive rod 5, whereby the window, the door or the like, for example, is unlocked. The double bearing of the mandrel 27 provided here through the bearing bore 34 of the guide 33 and the bearing opening 17 of the fitting element 4 is made possible by the circular cross section of the mandrel 27. As a result, the mandrel 27 is rotatably supported and guided in the bearing bore 34 and the bearing opening 17, so that over years always a precise and easy running of the operating handle 2 is guaranteed. Tilting or knocked-out and wobbly connections are thereby avoided. For lower torques to be transmitted fewer, for higher torque to be transmitted more projections (30,31; 36) or driving recesses (28,29) may be provided. By a corresponding arrangement of the driving recesses 28, 29 and the corresponding projections 30, 31, 36 and ribs 37, a rotational position assignment of operating handle 2, mandrel 27 and / or fitting component 21 can be realized, so that the mandrel 27, for example, only in a rotational angular position in the Operating handle 2 and / or in the Be impact member 21 can be inserted.

The guide 33 is formed as a bushing 38, which is partially inserted into the recess 32. For this purpose, the substantially circular cylindrical bush 38 has a (radial) support projection 39 extending over its entire circumference, which rests on a surface 40 of the casement 13 in the assembled state shown in FIG. It is conceivable to additionally fasten the bushing 38 to the sash frame 13 by means of screws. The bushing 38 has at its end facing away from the casement 13 end a substantially circular cylindrical projection 41 which engages in a receptacle 42 of the control handle 2, wherein projection 41 and receptacle 42 are arranged coaxially to the axis of rotation 22. On the outer circumference of the projection 41 and on the outer circumference of the inner surface of the receptacle 42 more Drehstellungsrastelemente 43 and Drehstellungsgegen- locking elements 44 are arranged on their function will be discussed later. In the receptacle 42 of the control handle 2 is formed as a locking washer 45 a fuse 46 which has a clamping bore 47 through which the mandrel 27 is inserted. In front- Partially, the locking washer 45 is fixedly arranged in the operating handle 2.

5 shows the operating handle 2, the mandrel 27, the lock washer 45 and the guide 33 in a perspective exploded view. The lock washer 45 has radially inwardly directed, the clamping bore 47 forming intrinsic elastic spring tongues 48 which are oriented obliquely in an (axial) direction, advantageously in the direction of the receiving recess 35 of the operating handle 2, so that the dome 27 in the direction of arrow 49 through the Clamping hole 47 of the locking washer 45 can be pushed. In a movement of the mandrel 27 in the opposite direction, the edges of the free ends of the spring tongues 48 are supported against the mandrel 27 or cut into it, so that the mandrel 27 on or in the fuse 46 is fixed. The mandrel is thus in one direction (in the direction of arrow 49) can be inserted into the fuse 46, but is prevented from moving in the opposite direction due to the Kantenabstützung or Kanteneinschneidung the spring tongues 48.

During assembly of the fitting arrangement 1, the fitting element 4 is first inserted into the open-edged receiving pocket 14 and the guide 33 or bushing 38 is inserted into the recess 32, then the mandrel 27 through the bearing bore 34 of the guide 33 in the bearing opening 17 of the housing part 9, wherein the mandrel 27 is guided through the opening 26 of the loading component 21. Finally, the operating handle 2 is pushed with the already attached thereto locking washer 45 on the mandrel 27 as far as desired. In the present exemplary embodiment, the operating handle 2 is pushed onto the mandrel 27 so far. pushed until it rests on the support projection 39 of the socket 38. Due to the Kantenabstützung / Kanteneinschneidung of the edge of the clamping bore or the spring tongues 48 of the operating handle 2 and the mandrel 27 in the operating handle 2 axially and due to the driving recesses 28, 29 and rotatably fixed. By the fuse 46 dimensional tolerances or differently thick executed wing frame (13), which lead to a different width protruding of the dome 27, are taken into account and compensated in a simple manner.

The mandrel 27 has in its lateral surface 50 designed as an annular groove 51 groove 52, which corresponds in the assembled state of the fitting assembly 1, as shown in Figure 3, with an open-edge receiving pocket 53 of the fitting element 4 and the housing part 9 of the fitting element 4. A self-elastic spring 55, which is formed as a U-spring 56 and consists of a spring wire 57, is located in the receiving pocket 53 as a securing element 54. The securing element 54 engages in the annular groove 51 of the mandrel 27, whereby the dome 27 is secured in the axial direction on or in the fitting element 4. The mandrel 27 is thus held or fixed axially immovably on the fitting element 4. The advantageous arrangement / design of the groove 52 or the annular groove 51 - seen from the operating handle 2 - behind the fitting component 21 and the transmission gear 20 has the advantage that a high torque can be transmitted from the operating handle 2 on the fitting component 21, without the risk of a torsional fracture of the mandrel 27 in the region between the operating handle 2 and the fitting component 21 due to a notch in the form of the groove 51 and the annular groove 52 is. The fixation by the Securing element 54 in connection with the axial fixation of the operating handle 2 by means of the fuse 46 causes the operating handle 2 occupies the desired axial position on the casement 13 and also complies. When inserting the mandrel 27 into the loading element 4, the securing element 54 or the spring 55 engages in the annular groove 51 (automatically). By shifting the securing element 54, the mandrel 27 can be released again. In this case, the securing element 54 and the annular groove 51 together form a releasable latching connection 58. The latching connection 58 and the non-detachable latching connection 59 formed by the securing disc 45 enable a particularly simple and uncomplicated assembly of the fitting arrangement 1. In the present exemplary embodiment according to FIG axially offset from the securing element 54, a second securing element 61 designed as a U-spring 60 is arranged, which rests in a second receiving pocket 62 of the housing part 9. The second receiving pocket 62 of the housing part 9 is - seen from the operating handle - in front of the fitting component 21 and spaced therefrom arranged. The second securing element 61 makes it possible for the fitting element 4 to be usable for both right-hand and left-closing windows, doors, or the like, since the mandrel 27 both from the one direction, as shown in Figure 3, as well as from opposite direction in the fitting element 4 can be introduced, in the latter case, the U-spring 60 engages for axially securing the dome 27 in the annular groove 51 and engages. The U-spring 56 or 60, which is first penetrated in the push-through direction by the mandrel 27, after completion of the assembly after the stop direction has been set, in the illustrated embodiment of the invention (Figure 3) has no further function. In order to facilitate a penetration of the first insertion spring 60 seen in the insertion direction / insertion direction of the dome 27, the groove 52 or the annular groove 51 preferably has a chamfer or insertion bevel in the insertion direction, so that the legs of the U-spring 60 can be disengaged with little effort can be bent apart and the mandrel 27 can be further introduced. Since the chamfer is formed only in the plug-in direction, the latching connection 58 for holding the mandrel 27 or the operating handle 2 on the fitting arrangement 1 is reliably retained.

To disassemble the fitting assembly 1, the U-spring 56 is first displaced so that their engaging in the annular groove 51 of the mandrel 27 legs are moved out of the annular groove 51 so that the mandrel 27 can be pulled axially out of the fitting element 4. Due to the permanent locking connection 59, which is essentially caused by the lock washer 45, the mandrel 27 can be pulled out by means of the operating handle 2, wherein the mandrel 27 remains on the operating handle 2. Subsequently, the fitting element 4 can be taken from the open-edge receiving pocket 14. For reassembly of the fitting assembly 1, the fitting element 4 is first inserted into the open-edge receiving pocket 14, and then the mandrel 27 is pushed by the operating handle 2 through the bearing bore 34 in the bearing opening 17 of the housing part 9 and thereby through the opening 26 of the fitting component 21 the U-spring 56 engages in the annular groove 51 of the mandrel 27 and engages. The mandrel 27 is thus inserted in a simple manner by means of the control handle 2 and axially fixed by the U-spring 56 and the securing element 54 in the fitting element 4. The guide 33 shown in perspective in FIG. 5, designed as a bushing 38, has four fixing elements 64 distributed over the periphery on its peripheral surface 63, which project as projections 65 from the lateral surface 63 and terminate axially with the support projection 39. The fixing means 64 are inserted into corresponding recesses in the casement 13, and thus serve as a positive rotation for the guide 33rd

The operating handle 2 associated portion 66 of the bushing 38 has the rotary position locking elements 43 shown in Figure 3, which are designed as Drehrastvorsprung 67 to cooperate with trained as Drehhrastvertiefungen 68 Drehstellungsrastgegenelementen 44 of the control handle 2. By means of a corresponding arrangement of the rotational position locking elements 43 and the rotational position locking counter elements 44, individual operating positions, such as, for example, locking position, rotational opening position and / or tilting opening position of the operating handle, can be predetermined. A user feels when pressing the operating handle 2 by the Drehstellungsrastelemente 43 and the Drehstellungsrastgegenelemente 44 in the corresponding rotational positions a certain Verarrungsvermögen the control handle 2. If the operating handle 2 are moved out of such operating position, so first the corresponding rotational locking position must be overcome by increased effort become.

The guide 33 or bushing 38 shown in FIGS. 3 and 5 is particularly suitable for casement frames (13) which are made of wood. For this purpose, initially four holes in the sash 13 are introduced, the radius of which is substantially the Radius of the fixing means 64 corresponds. Subsequently, the recess 32 is made as a bore with a diameter corresponding to the diameter of the lateral surface 63 of the bushing 38. The holes produced first are arranged such that they correspond to the arrangement of the fixing means 64. The first-made holes form after making the recess 32, the wells into which the locking means 64 engage. The bush 38, as well as the fixing means 64 advantageously have, as shown, insertion phases, which facilitate the insertion of the bushing 38 in the casement 13.

FIG. 6 shows an alternative bushing 69 designed as a guide 33 together with the securing device 46, the mandrel 27 and the operating handle 2 in an exploded view corresponding to that of FIG. 5. The bushing 69 has a circular cylindrical projection 70 which has the bearing bore 34. which can be inserted into a corresponding receptacle of a sash and whose axis of rotation corresponds to the axis of rotation 22. The projection 70 has a lateral surface 71, whose diameter is substantially smaller than the lateral surface 63 of the bush 38. Furthermore, the bushing 69 has a support projection 39 corresponding support projection 72 which is also formed as a radial projection. On the support projection 72 two fixing means 73 are arranged, which are formed as arranged parallel to the projection 70 pins 74. The pins 74 have a circular cylindrical cross section. Both the projection 70 and the pins 74 have at their free end in each case an insertion phase 75, which facilitate the mounting of the bushing 69 on the casement. FIG. 7 shows the bushing 69 in an enlarged perspective view. Like the bushing 38, the bushing 69 also has a projection 77 which can be inserted into the receptacle 42 of the operating handle 2 at its end 76 assigned to the control grip 2. On the lateral surface 78 of the projection 77 Drehstellungsrastele- elements 79 are provided, which are formed as radial projections 80 and with the Drehstellungsrastgegenelementen 44 of the operating handle 2, as described above, cooperate. The bushing 69 shown in FIGS. 6 and 7 is provided in particular for sash frames made of plastic.

For fastening the fitting arrangement 1 or the fitting element 4 on the casement 13, as shown in particular in Figures 2 and 4, provided in the housing part 9 four openings 81 through which, for example, a screw can be performed in the assembled state with their Screw head rests on a cross-sectional widening 82 of the openings 81. The drive rod 5 has openings 83 which correspond in a certain longitudinal position of the drive rod 5 to the housing part 9 with the openings 81, so that the screw can be introduced in the assembled state of the fitting element 4. For this purpose, the housing part 10 with the apertures 81 corresponding openings 84.

So that the drive rod 5 does not slip in the fitting element 4 during assembly, the fitting mechanism 3 can be blocked by a securing bolt, not shown here, in a bore 85 formed as a bore of the gearwheel 20 and in a receptacle corresponding thereto in a specific rotational position of the gearwheel 20 86 of the housing part 9 inserted becomes, so that a rotation of the transmission gear 20 is prevented.

FIG. 8 shows a part of the fitting arrangement 1 in an exploded view. The housing part 10 has four retaining bolts 87, which are arranged such that they can be inserted into corresponding retaining openings 88 of the housing part 9. When assembling the fitting assembly 1, the drive rod 5 is enclosed during mating of the housing parts 9 and 10 of these in the region of the recesses 25, so that the drive rod 5 longitudinally displaceable in the striking element 4, as shown in Figure 3, is mounted. A recess 25 'of the recesses 25 is formed so wide that the transmission gear 20 can be axially inserted with a tooth 24 in the recess 25'. Alternatively, the transmission gear 20 is first inserted into the recess 19 of the housing part 9 and optionally locked therein by means of a securing bolt, as described above. The securing elements 54, 61 can be introduced before or subsequently into the receiving pockets 53 and 62, respectively. The securing elements 54 and 61, which are designed as U-springs 56 or 60, have run-on bevels 89 at their "open end" which cooperate with the fitting element 4 in such a way that they require more than the locking of the mandrel 27 be pressed, the U-springs 55, 60 are spread open and so release the mandrel 27, so that it can be pulled out of the fitting element 4. It is also conceivable to make the ramps 89 such that by partially pulling out of the U Spring 56 from the receiving pocket 53, the U-spring 56 is spread and thus releases the mandrel 27. FIG. 9 shows in a perspective rear view, corresponding to that of FIG. 5, an exploded view of an alternative bushing 90 forming the guide 30, which substantially corresponds to the bushing 69 of FIG. 7, so that the same reference numerals are used for the same features and only on the differences should be addressed. The bush 90 has a substantially oval cross section with two opposite, parallel to each other arranged straight sides. The fixing means 73 are formed as Spreizpins 91, wherein the Spreizpins 91 have an opening 92 parallel to the bearing bore 34.

FIG. 10 shows the exploded view of FIG. 9 in a perspective plan view. The Spreizpins 91 act as expansion dowels, wherein a screw for fixing the guide 33 and the sleeve 90 is screwed to the sash 13 in the opening 92, whereby the Spreizpin spreads and locks the guide 33.

Furthermore, FIGS. 9 and 10 show a rosette 93 whose cross-section substantially corresponds to that of the bushing 90. The rosette 93 has an opening 94, through which the projection 77 of the guide 30 and the sleeve 90 can be performed. During assembly, the bushing 90 is first attached to a casement, for example by means of screws as described above. Subsequently, the rosette 93 is placed on the sleeve 90 in the direction of the arrow 95, so that the openings 92 are covered. For this purpose, the rosette 93 has two latching elements 96, which engage when plugged onto the socket 90 in a receptacle 97 of the socket 90. For this, the rosette 93 is preferably at least partially intrinsically elastic. The rosette 93 has in particular visual advantages and seals the fitting assembly to the outside if necessary. Subsequently, the mandrel 27 in the direction of arrow 95 through the bearing bore 34 in the fitting element 4, as described for the figures 3 and 4, inserted. The locking washer 45 is first secured in the operating handle 2, which is then attached in the direction of the arrow 95 on the mandrel 27. In this case, the locking washer 45, as already mentioned above, the locking connection 59 which locks the operating handle 2 axially.

11 shows a sectional view of an embodiment of an advantageous development of the dome 27. Here, the mandrel 27 in its lateral surface 50 has a further, designed as an annular groove 98 groove 99 which is spaced apart from the annular groove 51, that during assembly For example, according to Figure 3, each one of the U-springs 56, 60 engages in an annular groove 51, 98. As a result, the security against pulling out of the handle 2 is increased from the fitting gear 3. The first annular groove 51 in this case has a chamfer 100, which is aligned in the insertion direction, so that the mandrel 27 when inserting the - seen in the insertion direction - first U-spring 60 (or 56) can easily penetrate. By this chamfer 100, the first U-spring 60 (or 56), which initially engages when plugging into the annular groove 51, widened during further insertion of the dome 27, so that the first latching loosened again and the mandrel 27 further into the fitting gear third or the fitting element 4 can be inserted. In the introduced state of the mandrel 27 according to FIG. 3, the second annular groove 98 together with the corresponding U-spring 60 would form a further latching connection, which prevents unintentional release of the handle 2 from the fitting element 4. Of course, it is also conceivable to provide only the second groove 99 or annular groove 98 on the mandrel 27, which - viewed from the operating handle 2 - arranged or formed in front of the fitting component 21 in the lateral surface 50 of the mandrel 27. This would have the advantage that in the insertion process of the mandrel 27, when the two U-springs 56, 60 are provided, a latching and releasing again one of the U-springs 56, 60 (namely, the first to be penetrated) is eliminated. The mandrel 27 can be inserted directly to its locking position.

FIG. 12 shows a further exemplary embodiment of the fitting arrangement 1 in an exploded view, which essentially corresponds to that of FIG. In contrast to the previous embodiment, the housing parts 9 and 10 of the housing 8 and the fitting element 4 are identical as turning shells 101, 102, formed. The housing parts 9, 10 or turning shells 101, 102 each have according to FIG. 12 both retaining bolts 87 and retaining openings 88. In contrast to the preceding exemplary embodiment, the openings 81 are additionally formed here proportionally by the turning shells 101, 102 or housing parts 9, 10. By the corresponding arrangement of the different elements of the identical housing parts 9, 10 or turning bowls 101, 102, as is common in turning bowls or identical (collapsible) housing parts, a simple mating the identical housing parts 9, 10 to form the housing 8 to simple Way guaranteed. By providing the identical housing parts 9, 10, the manufacturing cost of the fitting assembly 1 is reduced and prevents incorrect assembly. The turning shells 101 and 102 further each have a locking projection 103 which protrudes in the assembled state of the housing 8 in the opening 85 of the gear wheel 20 and thus the transmission gear 20, for example, for pre-assembly of the fitting assembly 1, locked. The locking projection 103 is advantageously so integrally formed with the respective turntable 101, 102 or with the respective housing part 9, 10, that it tears at a first actuation of the fitting assembly 1 by a rotational movement of the gear wheel 20 and / or is depressed and thereby the locking of the gear wheel 20 is solved.
