The invention relates to an actuating gear for window and / or door fittings with adjusting and / or locking rods or the like.

• with a housing which can be fastened to the sash or frame, preferably to be placed on the end face thereof,
• with a pinion rotatably mounted in the housing, which is provided with a toothing area over part of its circumference and can be rotated by an operating handle,
• with a tooth piece which is guided in a longitudinally displaceable manner and meshes with the toothing area of the pinion and
• with at least one driver tab protruding from the tooth piece for the actuating and / or locking stands or the like, which projects out of the housing, for example through a slot in a base plate, and
• wherein the housing is designed symmetrically to a transverse plane going through the axis of rotation of the pinion or operating handle - in the longitudinal direction.

Actuators of this type are already widely known and - mainly in connection with light metal and plastic windows and doors - in practical use.

EP 0 491 133 B1 discloses a generic actuation gear as known, in which a housing which can be placed on the end face of the wing or frame rotatably supports an operating handle. The operating handle is connected to a pinion, which is toothed over its entire circumference - 360 °. Two tooth pieces which are longitudinally displaceably guided in opposite directions and mesh with the pinion on diametrically opposite circumferential sides each have a drive tab projecting from the rear and projecting through a slot in a bottom plate which is detachably connected to the housing and which can be coupled with an actuating and / or locking linkage. In order to enable the stop direction of this actuating gear to be converted, the tooth pieces are designed symmetrically to a transverse plane through their driving lobes and can optionally be inserted in two positions that are longitudinally offset relative to the transverse plane of the housing without twisting into the housing, and thereby via their toothing with the pinion toothing couple. Actuating gears of this type are used to drive two actuating and / or locking rods that can be moved in opposite directions.

The maximum achievable stroke that the adjusting and / or locking linkage can produce is naturally determined by the pitch circle diameter of the pinion. It is disadvantageous that the pinion diameter and thus the housing dimensions must be increased accordingly for a large stroke.

The main object of the invention is therefore to generate a maximum stroke for actuating gears of the type specified at the beginning with minimized gear dimensions.

In the conventional actuating gears, it is often also disadvantageous if the actuating force which can be achieved on the actuating and / or locking linkage remains the same over the entire switching path. For certain switching positions, such as engaging in the locking position, however, it is desirable to achieve a higher actuation force in order to reduce the frictional resistance to be able to overcome the interacting locking elements more easily.

The invention is therefore also based on the object of developing an actuating gear with a large stroke in such a way that the greatest possible operating forces can be transmitted in the rotational angle range of the operating hand lever with strong mechanical loads.

Windows, doors or the like, which can be equipped with a generic actuating gear, can be found, for example, in the brochure "GU parallel sliding and tilting fitting G.U.-966 for wooden doors and windows". There is an actuating gear used for a sliding sash, which can first be lifted perpendicular to the plane of the frame and then moved parallel to the frame level behind an adjacent sash or a fixed field, which is placed on the end face of the sash and one in the sash rebate arranged fitting drives, which is connected to upper opening devices. By turning the rotary handle by 90 °, the sash is transferred into a locked tilting position, with upper opening devices forcing the sash down. In order to open the sash fully, the lower sash fixation can be released by turning the operating lever by approx. 40 °. The wing can now also be extended in parallel at its lower end and then moved laterally. The operating handle is automatically returned to the 90 ° position via a spring system and then remains in a horizontal position.

It is unsatisfactory that with such actuating gearboxes the 180 ° rotation of the operating hand lever, which is generally common in the vast majority of connecting rod fittings, is not possible. However, it is also disadvantageous that a special actuating gear is required for windows and doors with leaves that can be moved to the right or left. This results in considerable manufacturing and storage costs.

It is therefore a further object of the invention to improve the known actuating gear so that, in addition to the smallest possible size and a large stroke, they offer a universal application for both right and left wing.

From DE 91 12 079 U1 an actuating gear for longitudinally displaceable drive rods on fittings of windows and doors or the like has become known that works as a large-stroke gear and the operating handle can be pivoted through 180 °. With a special translation mechanism, a relatively large stroke is generated for the dimensions of the transmission. This gearbox is intended for installation in the sash rebate and requires chiselling or milling work to form a receiving pocket on the sash for inserting the gearbox housing.

• daß dieser Zahn größerer Zahnbreite den Verzahnungsbereich des Zahnstücks in einer bestimmten Schaltstellung des Stell- und/oder Verriegelungsgestänges zugeordnet ist,

An actuating gear of the generic type is basically characterized according to the invention in that

• that at least one tooth in the toothing area of the pinion has a larger tooth width than the other teeth,
• that this tooth of larger tooth width is assigned to the toothing area of the tooth piece in a certain switching position of the actuating and / or locking linkage,
• that the toothed piece has a cantilever which is parallel to the plane of rotation of the pinion and has a toothing region projecting from the top,
• that the cantilever protrudes into the movement path of the section of the tooth of larger tooth width projecting beyond the normal tooth width,
• that there is a cutout or a groove in the boom with a guide contour associated with the projecting section of the tooth having a larger tooth width and
• that the cutout or the groove is assigned to the toothing area of the tooth piece for the specific switching position of the actuating and / or locking linkage.

The advantage of this new design of an actuating gear is that tooth piece and pinion on the one hand are operatively connected via intermeshing teeth, but on the other hand work together in the manner of a sliding link crank or eccentric drive.

It has proven itself in an actuation gear according to the invention if the guide contour of the cutout or of the groove in the cantilever forms a circular arc over a certain angular range away from the toothing region of the tooth piece, and if the center of this circular arc at the specific sliding position of the actuating and / or Locking rod aligned with the axis of rotation of the pinion or operating handle.

It also proves to be advantageous for the invention if the guide contour of the cutout or the groove provided in the cantilever has, in its section adjoining the toothing region of the tooth piece, a curve shape which deviates from the circular arc and projects out of it in a cam-like manner.

It is also useful in an actuation gear according to the invention if the tooth having the larger tooth width than the other teeth is arranged at one end of the toothing region of the pinion and if the cutout associated with the projecting section of the tooth of larger tooth width in the extension arm or the groove with the guide contour is itself is located at the associated end of the toothing area of the tooth piece.

A further advantage of this new design of an actuating gearbox results when the tooth of the toothing region, which has the larger tooth width, has portions protruding on both sides beyond the flat surfaces of the pinion and the pinion is symmetrical with respect to its center plane of rotation, while the tooth piece has a symmetrical design with a central transverse plane , and has a cutout or a groove with a guide contour assigned to the projecting sections of the tooth with a larger tooth width on both sides of this transverse plane in the boom. This ensures that the same components are used for both a right and a left wing.

• mit einem auf die Stirnfläche des Fenster- und/oder Türflügels oder -Blendrahmens aufsetzbaren und daran befestigbaren Gehäuse,
• mit einem im Gehäuse drehbar gelagerten Ritzel, daß durch einen Bedienungshandgriff verdrehbar ist,
• und mit mindestens einem vom Zahnstück abstehenden, sowie durch einen Schlitz in einer lösbar mit dem Gehäuse verbundenen Bodenplatte hinausragenden Mitnehmerlappen,
• wobei das Gehäuse einerseits zu einer durch die Drehachse des Ritzels bzw. Bedienungshandgriffs gehenden Querebene - in Längsrichtung - symmetrisch gestaltet ist,
• und wobei das Gehäuse andererseits bezüglich einer vom Schlitz der Bodenplatte bestimmten Bewegungsebene der Mitnehmerlappen - in Querrichtung - unsymmetrisch ausgeführt ist,

ergibt sich, eine zweckentsprechend einfache Umbaumöglichkeit wenn Ritzel und Zahnstück gemeinsam aus dem Gehäuse entnehmbar vorgesehen sind, wenn das Ritzel außerhalb des Gehäuses in zwei um 180° gegeneinander gewendeten Lagen mit der einen oder anderen zur Querebene des Zahnstücks spiegelbildlichen Hälfte von dessen Verzahnungsbereich und des Auslegers in Eingriff bringbar ist und wenn dann Ritzel und Zahnstück gemeinsam wieder in das Gehäuse einsetzbar sind.In an actuating gear according to the invention, which

• with a housing that can be placed on and attached to the end face of the window and / or door leaf or window frame,
• with a pinion rotatably mounted in the housing, which can be rotated by an operating handle,
• and with at least one driver tab projecting from the tooth piece and projecting through a slot in a bottom plate detachably connected to the housing,
• the housing is, on the one hand, symmetrical in relation to a transverse plane going through the axis of rotation of the pinion or operating handle, in the longitudinal direction,
• and the housing, on the other hand, is designed asymmetrically with respect to a plane of movement of the driver tabs determined in the slot of the base plate, in the transverse direction,

This results in a suitably simple conversion option if the pinion and tooth piece are provided removable from the housing together, if the pinion outside the housing in two positions turned 180 ° against one another with one or the other half of the toothing area and the extension mirroring the transverse plane of the tooth piece can be brought into engagement and if the pinion and tooth piece can then be reinserted into the housing together.

A further advantageous embodiment of such an actuation gear according to the invention is possible if the pinion in each of its two possible turning positions can be brought into a detachable, but non-rotatable, form-fitting plug connection within the housing with a drive mandrel of the actuation handle.

For all of the above-mentioned actuating gears according to the invention, an embodiment proves to be advantageous in which the pitch circle diameter of at least one tooth, which is located on the end of the toothing area opposite the larger tooth width, is smaller than the pitch circle diameter of the other teeth, and that this at least a tooth is assigned to the tooth piece in the closed switching position of the actuating and / or locking linkage.

An actuation gearbox according to the invention can also be further improved by the fact that the operating handle contains latching means which cooperate with latching recesses in the housing and indirectly determine the various switching positions of the actuating and / or locking linkage.

An advantageous embodiment also results if fastening elements serving to fasten the actuating gear on the end face of the frame penetrate pairs of through holes in the housing, and if such pairs of through holes are each arranged in a plurality of planes offset from one another transversely to the longitudinal plane of the housing.

For an actuation gear according to the innovation, it also proves to be advantageous if the base plate contains a bearing hole into which the end of the drive mandrel carrying the pinion projects.

It has proven itself in an actuation gearbox according to the invention if the drive mandrel as seat for receiving the pinion has a polygonal cross-section, preferably a square cross-section, at least in sections, which engages through the pinion in a complementarily shaped recess, while its free end forms a centering mandrel, which in its Diameter corresponds almost to the side length of the polygonal cross section of the drive mandrel.

A further advantageous embodiment results if the base plate is a sheet metal part.

According to the invention, it also proves to be advantageous if the pinion, which is coupled in a rotationally fixed manner with its drive mandrel, has a toothing region which extends only over an angular range of less than 180 °, for example over 115 °, and if the pinion with the toothed piece extends over the angular difference region or the angular difference sector away by the engagement of the projecting portion of the tooth of larger tooth width in the Cutout or the groove of the boom is held in clutch engagement.

A window, a door or the like. Which or which is provided with an actuating gear of the new configuration, wherein the window or the door has a wing that can be lifted to open first perpendicular to the plane of the frame and then parallel to the plane of the frame can be moved behind an adjacent sash or a fixed field, with upper and lower runners for the engagement elements of the sash extension arms of upper opening devices and of lower runners of the sash, respectively, on the frame, which in the fitting fold of the sash - behind the sash overlap - an adjusting and / or locking linkage is assigned, and wherein each extension arm at least the upper opening device with its engaging element in each position of the wing is on the one hand in constant engagement with the upper running rail arranged in front of the inner frame level, while on the other hand each upper opening device ung is connected to the actuating gear from controllable actuating and / or locking linkage, is advantageously further developed if there is a possibility that
Pinion and tooth piece are provided together after removal and removal of the base plate removable from the housing,
the pinion outside of the housing can be brought into engagement with one or the other half of the toothed region, which is mirror-image to the transverse plane of the toothed portion and the cantilever, in two positions that are turned against each other, and then
The pinion and tooth piece can be reinserted together in the housing before the base plate is attached to the housing.

Fig. 1 shows a purely schematic representation of an embodiment of an actuating gear 1, which is attached with its housing 2 on the end face 3 of a wing 4. The actuating gear 1 has at least two switching positions. In the illustrated embodiment, a closed position A, a first open position B, e.g. a tilting position and a second opening position C, for example a rotating or sliding position for the wing 4, which can be adjusted by an operating handle 5. In the closed position A, the wing 4 is firmly connected to the frame (not shown) by means of locking parts which can be moved by adjusting and / or locking rods. For the tilt position (open position B), these locking parts are released, after which the wing 4 can then be tilted about a horizontal axis at its lower end. In the exemplary embodiment shown, the open position C allows, for example, the sash 4 to be set off parallel to itself from the frame and to be moved sideways in this setting plane.

In Fig. 2 it can be seen that the housing 2 of the actuating gear 1 is box-shaped and is surrounded on all sides by a cover cap 6. The cover cap 6 can be held on the housing 2 by - not shown - snap-in connections. The operating handle 5 is e.g. rotated in the housing 2 by an angle of 180 °. Its axis of rotation 7 extends axially through a drive mandrel 8, on which a pinion 9 with a receptacle 9a designed to complement the cross-sectional shape of the drive mandrel 8 is also axially aligned on the housing 2. The pinion 9 has a toothing area 10 which meshes with a toothing area 11 of a tooth piece 12 which is longitudinally displaceable in the housing 2.

The toothing region 10 of the pinion 9 extends in the example shown over an angular range of less than 180 °, eg over 115 ° and is equipped at one end 13 with a tooth 14 which has a larger tooth width 14a than the other teeth 15 - not visible in this illustration. At the other end 16 of the toothing region 10, a tooth 17 is provided, the pitch circle diameter 18 of which is smaller than the pitch circle diameter 19 of the other teeth 14, 15. The tooth 17 has the same tooth thickness as the teeth 15.

The toothed piece 12 has a cantilever 20 which is parallel to the plane of rotation of the pinion 9 and projects beyond its toothing region 11 on the head side. This contains a cutout or a groove 21 with which the section 27 of the tooth 14, which is not visible here and which projects beyond the flat surface of the pinion 9, cooperates.

The mode of operation of such an actuating gear 1 is explained below with reference to FIGS. 3a to 3d, all gear components which are not directly required being omitted there for a better overview.

Fig. 3a shows the actuating gear 1 in the closed position A, in which the pinion 9 meshes the tooth piece 12 with its tooth 17. Since the pitch circle diameter 18 of the tooth 17 is dimensioned smaller than the pitch circle diameter 19 of the other teeth 15, there is a more favorable ratio for the force transmission in this position. In the present case, this fact is exploited to bring the locking elements into positive engagement with one another with an increase in force in the switching direction towards the closed position of the actuating and / or locking linkage. By shortening the lever arm from the pitch circle diameter 19 to the pitch circle diameter 18, a naturally higher torque is transmitted, although the resulting stroke of the toothed piece 12 is smaller.

If the actuating gear 1 is moved from the closed position A to the tilt position B, the engagement position according to FIG. 3b results. The tooth piece 12 is shifted by the stroke 25 from its previous position. The tooth 14, which has the larger tooth width 14a, is over the flat surface of the pinion 9 protruding section 27 immersed in the cutout or the groove 21 of the bracket 20 and in the embodiment is almost on the right guide contour 26 of the cutout or the groove 21.

In Fig. 3c, an intermediate position is shown, which shows that the tooth 14 also fully engages in the toothed region 11 of the tooth piece 12. Since the cutout or the groove 21 extends into the toothing region 11 of the tooth piece 12, the tooth 14 thus comes fully into engagement with the tooth piece 12 via its larger tooth width 14a.

If the actuating gear 1 is further rotated by the operating handle 5 so that an end position pivoted by 180 ° with respect to the starting position is set, then the tooth 14, as FIG. 3d makes clear, moves out of the toothed region 11 of the tooth piece 12 and slides with it on the underside of the pinion 9 above its flat surface projecting section 27 along the right guide contour 26 of the cutout or the groove 21 in the extension arm 20. As a result, the toothed piece 12 is moved further by an additional stroke 29, although the tooth 14 is no longer with the toothed area 11 of the tooth piece 12 combs, but is disengaged from this.

In an end position of the pinion 9 pivoted by 180 ° with respect to the starting position according to FIG. 3a, the tooth 14 and thus also its projecting section 7 is almost on a right angle to the guide contour 26 and both the axis of rotation 7 of the operating handle 5 or pinion 9 as well the longitudinal edge 20a of the boom 20 intersecting line.

This ensures that the toothed piece 12 cannot be moved from the right to the left relative to the pinion 9. This would be possible, for example, through forces acting indirectly on the actuating and / or locking linkage, which act indirectly on the toothed piece 12.

The interaction of the tooth 14 equipped with the larger tooth width 14a via its projecting section 27 with the guide contour 26 of the arm 20 ensures a permanent engagement of the pinion 9 in the tooth piece 12, although the toothing area 10 of the pinion 9 only extends over an angular area, which is not significantly larger than 90 °, e.g. B. is 115 °.

A special feature of the illustrated embodiment of the guide contour 26 of the cutout or of the groove 21 in the arm 20 is that it forms an arc 31 over a certain angular range 30 and that the center 31a of this arc 31 in the open position C shown in FIG. 3d of the actuating and / or locking linkage is aligned with the axis of rotation 7 of the pinion 8.

When the actuating gear 1 is actuated in the reverse direction, the projecting section 27 of the tooth 14 initially slides without causing the tooth piece 12 to move from right to left, along the guide contour 26 until it strikes a wall 32 which engages the cutout or the Groove 21 bounded on the left side opposite the guide contour 26. As soon as the projecting section 27 of the tooth 14 comes into contact with the wall 32, the tooth piece 12 is carried along until the toothing regions 10, 11 come fully into engagement again.

The guide contour 26 adjoins a tooth flank in the toothing region 11 of the tooth piece 12 via a circular arc section 28 which has a curvature opposite to the circular arc 31. This results in a slightly S-shaped curve of the entire guide contour 26, which results in good sliding thrust kinematics.

4 and 5 each show the actuating gear 1 in a bottom view for right and left stop, the bottom plate closing the housing 2 not being shown.

In order to be able to adapt one and the same actuating gear 1 to the two different stop situations, For example, special precautions have been taken for a parallel sliding sash for left sashes that are shifted to the right or for right sashes that are shifted to the left. This is because the pinion 9 can be pulled axially out of the position 36 according to FIG. 4 from the drive mandrel 8, at least in sections formed as a square 35, and plugged back together with the drive mandrel 8 in a position 36 ′ according to FIG. 5 which is turned through 180.degree , or be reinserted in the housing 2. In order to remove the pinion 9 from the housing 2, it is also necessary to remove the toothed piece 12 together with the pinion 9. For this purpose, the middle switching position (tilt position B) is expediently set on the operating lever 5.

The tooth piece 12, as can be seen from FIGS. 3a to 3d, is configured symmetrically to a central transverse plane 37-37 and has a cutout or a groove 21 (a) or 21 (b) on both sides of this transverse plane 37-37 in the bracket 20 a guide contour 26 assigned to the projecting sections 27 of the tooth 14.

It is also important that the pinion 9 according to FIGS. 7 and 8 as a whole is mirror-inverted with respect to its center of rotation 38-38 and in the region of the tooth 14 a section 27 (a) and (b) of each of the two flat surfaces (100 (a) and 100 (b) of the pinion 9 protrude.

The housing 2 is designed symmetrically with respect to a transverse plane 39-39 which leads through the center plane of rotation.

The use of the drive mandrel 8 designed as a square 35 allows a non-rotatable but releasable form-fitting plug connection with the pinion 9.

3a to 3d, the pinion 9 and the tooth piece 12 are brought into engagement with one another for an actuating gear 1, as shown in FIG. 4 in the bottom view and is suitable for a right-hand stop on the wing (cf. FIG. 1).

If the actuating gear 1 is to be converted or assembled in such a way that it is suitable for the left-hand stop with the arrangement of the gear members apparent from the bottom view according to FIG. 5, then the pinion 9 and tooth piece 12 must be brought together so that they are shown in FIGS to 3d corresponding switch positions each have a mirror-image engagement position. This is characterized in that it is not the portion 27 (a) of the tooth 14 projecting over the flat surface 100 (a) of the pinion 9 that interacts with the cutout or the groove 21 (a) of the arm 20, but rather that over the flat surface 100 ( b) the cutout 27 (b) of the tooth 14 projecting from the pinion corresponds to the cutout or the groove 21 (b) of the arm 20.

By axially pulling the pinion 9 from the square 35 of the drive mandrel 8 and removing the tooth piece 12 from the housing 2, the two functional parts (pinion 9 and tooth piece 12) can be regrouped outside of the housing 2 without any problems.

As can be seen from Fig. 1, several z. B. three switching positions A, B, C of the actuating gear 1 possible. In order to at least signal to an operator that each of these switch positions A, B, C has been reached, it is provided to use special latching means 40. 8, can be accommodated in a handle neck 42 of the operating handle 5 and cooperate with locking recesses 41 on the housing 2. The various switching positions A, B, C of the actuating and / or locking linkage are characterized by the number and distribution of the remaining recesses 41.

For fastening the actuating gear 1 with its housing 2 on the end face of a window or door leaf 4, fastening elements penetrate through bores 45 in the housing cover 46. These through bores 45 are accessible when the cover cap 6 is removed from the housing 2. The through bores 45 are each provided in pairs on a plurality of planes 48, 48 ' , 48 '' which are laterally offset from one another and parallel to a longitudinal axis 47 of the housing 2, one of which, for example the plane 48 ″, can coincide with the longitudinal plane 47 of the housing 2 going through the axis of rotation 7 of the operating handle 5 and the pinion 9.

As can be seen in FIGS. 6a, 6b and 6c, the configuration of the housing 2 with several pairs of through holes 45 for fastening elements 54 located on mutually offset levels 48, 48 ' , 48 '' results from the different installation conditions on different wing profiles 50 .

6a shows e.g. B. the installation situation for a plastic hollow profile 51 with a metal reinforcing profile 52 seated in the plastic hollow profile 51. The plastic hollow profile 51 has an undercut fitting groove 53 receiving the actuating and / or locking linkage. According to FIG. 6 a, fastening elements 54 penetrate the through bores 45 lying on the plane 48 ′ and fasten the housing 2 of the actuating gear 1 on the end face 3 of the hollow plastic profile 51 by anchoring them in the metal reinforcing profile 52.

In the embodiment shown in FIG. 6 b, the plastic hollow profile 51 is also stiffened with a reinforcement profile 52, but this does not extend along the profile wall forming the rear face 3. Here, the attachment of fastening elements 54 on the plane 48 'can be difficult because a profile web 56 abuts the profile wall having the end face 3 perpendicularly on this plane 48'. According to FIG. 6b, the fastening elements 54 are therefore introduced on one of the other levels 48 or 48 ″ . However, it is also possible, for. B. with large forces to be transmitted from the actuating gear 1, fasteners 54 on several levels (48 and 48 '' ) at the same time. This ensures a permanently secure hold of the actuating gear 1 on the end face 3 of the wing profile 50.

6c, the actuating gear 1 is attached to the end face 3 of a wing profile 50 made of wood or other solid material. It can be seen there that each of the three levels 48, 48 ' , 48 '' for attaching fastening elements 54 would be possible, although their arrangement there is only shown on level 48 ' .

It can also be seen in Fig. 6c that the driver 61 of the toothed piece 12 serving to transmit the translatory movement generated by the actuating gear 1 to the actuating and / or locking linkage 62 through a longitudinal slot of the wing profile 50, for. B. in the area of its flap 55, passes through.

FIG. 7 shows a cross section through the actuating gear 1. Its operating handle 5 has in its grip neck 42 a recess 66, which is complementary to the drive mandrel 8 and in which the drive mandrel 8 is seated in a form-fitting manner. At the end 67 of the handle neck 42, a ring 68, for example fixed by a riveting process, is fastened, which has latching recesses 41 on its outer circumference. The handle neck 42 is rotatably mounted in a bore 69 which penetrates a shoulder 70. Due to the arrangement of the ring 68 and the design of the bore 69, the operating handle 5 is rotatably but axially immovably connected to the housing 2. The pinion 9 is seated on the drive mandrel 8 and meshes with the toothed piece 12 through toothings.

The drive mandrel 8 can be provided at its free end 75 with a cylindrical pin 76 which almost reaches a seat 77 of the pinion 9. The cylindrical pin 76 protrudes into a complementarily shaped bearing hole 78 of a bottom plate 79 closing the housing 2.

This ensures that the relatively high side forces that can arise in gear connections of the type described above can be safely absorbed. The drive mandrel 8, which thus acts as a double-bearing shaft, is thereby protected from deformation.

In order to offer the largest possible receptacle 80 to the cylindrical pin 76, an inwardly directed retainer 81 is formed on the base plate 79 made of sheet metal.

8 shows, on an enlarged scale, a cross section of the actuating gear 1 through the handle neck 42 and the housing 2 along the section line VIII-VIII in FIG. 2.

Here, the locking means 40 consists of a compression spring 90 which is directed parallel to the axis of rotation 7 and which acts on a ball 91. The different switching positions of the operating handle 5 are marked by four latching recesses 41, each at a 90 ° angle to one another, on the flat surface 92 of the extension 70. In each of the four possible snap-in recesses 41, the ball 91, which is under the spring force, partially engages in the snap-in recess 41 and brings about a catch that is clearly noticeable to the user.

In the exemplary embodiment according to FIG. 8, the connection of the operating handle 5 to the housing 2 is accomplished by a retaining ring 94 seated in a circumferential groove 93 of the handle neck 65. The locking ring 94 is arranged in front of a disk 95, which is larger in its outer dimensions than the bore 69 made in the shoulder 70. The flat surface 92 is formed by a plate 96 which covers the shoulder 92 on the end face and is made of low-wear material, which is rotationally fixed, for. B. is held by a protruding from the shoulder 92 and projecting into the underside of a locking recess 41 pin 97.

It can also be seen in FIG. 8 that the tooth 14 has a larger tooth width than the other teeth of the pinion 9. Therefore, the section 27 (a) and (b) protrudes over each of the two flat surfaces 100 (a) and (b) of the pinion 9.

8 also shows that the tooth piece 12 is held in a U-shaped guide 101 of the housing 2 so as to be longitudinally displaceable. The cantilever 20 underpins the pinion 9 on the underside of the housing 2 above the base plate 79. It can also be clearly seen that the pinion 9 has a seat 77, the thickness 102 of which can be greater than the pinion thickness. This ensures that the pinion 9 is easily pushed onto the drive pin 8 via the cylindrical pin 76 can be, if the pin 76 is dimensioned slightly smaller in diameter than the side distance on the drive mandrel 8 designed as a square. The base plate 79 closes the housing, not only fixing pin 103 of the housing 2, but also a coupling driver 104 by means of corresponding bores Tooth piece 12 protrude through a slot 105.

The fixing pins 103 fit into holes in the wing profile and serve to secure the position of the actuating gear 1 on the end face of the wing 4 during its assembly and in later operation. The drill holes and the longitudinal slots 60 penetrated by the coupling driver 104, which can be seen in FIG. 6c, are usually introduced by means of combined drilling and milling templates in order to ensure a clear mutual association.

The assignments of toothed areas 10, 11 of the pinion 9 and tooth piece 12 as well as of the tooth 14 equipped with a larger tooth width 14a compared to the other teeth 15 in the exemplary embodiments can of course also be chosen differently if special, bound to a certain switching position, Tasks must be performed. This can be the case, for example, if particularly high switching forces or special lifting movements bound to intermediate switching positions are to be transmitted to the actuating and / or locking linkage.

The use of an actuating gear, as shown in the exemplary embodiments, can be carried out on any window or door fitting.

However, there are special advantages when using the actuating gear on doors or windows according to FIGS. 9a to 11b.

9a to 11b of the drawing each show a balcony or terrace door, which in a fixed frame 110 has fixedly mounted wings or a fixed door field 111 and which is also equipped with a movable wing 4.

The movable wing 4 can be brought relative to the fixed frame 110 and to the fixed wing or door panel 111 from the closed position indicated in FIGS. 9a and 9b on the one hand into the tilt opening position, as can be seen in FIGS. 10a and 10b . On the other hand, it can also be brought into a parallel position relative to the fixed frame 110 and the fixedly mounted wing or fixed door panel 111 and then in the horizontal direction in front of the fixed wing or fixed area from the area of the passage opening 112 of the fixed frame 110 Move door panel 111, as can be seen from FIGS. 11a and 11b.

So that these three positions of the sash 4 relative to the fixed frame 110 and to the fixed sash or to the door panel 111 are possible, a special fitting arrangement, namely a so-called tilting parallel sliding fitting, is provided between the sash 4 and the 9a to 11b, for the sake of simplicity, only the operating gear 1 on the wing 4 and the upper opening device 113 and the lower opening device 114 between the wing 4 and the fixed frame 110 can be seen.

The upper opening device 113 and the lower opening device 114 can be designed kinematically similar to one another. In principle, however, you can also obtain different configurations.

In the upper opening device 113, it must be ensured that the articulation points on the room side constantly engage in a horizontal sliding guide 115 on the upper cross member of the fixed frame 110 and that a synchronous movement of their opening arms is ensured.

In any case, the lower opening device 114 is to be designed such that it securely holds the weight of the movable wing 4 carries while cooperating with a track 116 on the lower cross member of the fixed frame 110.

The actuating gear 1 drives the actuating and / or locking linkage 62 (not visible here) which, in the closed position A according to FIGS. 9a and 9b, interacts with locking elements 118 fixed in the frame fold 117 - as can be seen in FIG. 11a. If the wing 4 is to be moved into the open position according to FIGS. 10a and 10b, the actuating gear 1 is brought into the corresponding switching position B according to FIGS. 10a and 10b. The upper opening devices 113 are actuated via the actuating and / or locking linkage 62 and cause the wing 4 to be lowered from the frame 110. The lower horizontal end of the wing 4 is held on the frame 110 in this switching position by locking elements (not visible here).

If the wing 4 is moved from the open position B to the open position C, here parallel storage position, by actuating the actuating gear 1 in the exemplary embodiment shown by a further 90 °, these locks are also released and the wing 4 can now also be turned off at its lower horizontal end and then be moved laterally.

In order to achieve the forced shutdown of the wing 4 from the closed position A to the open position B or vice versa, the pulling of the same into the closed position A, special display devices 113 are necessary which are connected to the actuating and / or locking linkage 62 which can be controlled by the actuating gear 1 are. In order to be able to control the opening movement of each of the upper and possibly even the lower opening devices 113, on the one hand large movement forces and on the other hand large lifting movements of the actuating and / or locking linkage 62, which are generated by the actuating gear 1, are necessary.

It can also be deduced from FIGS. 9a, 10a and 11a that for a wing 4, one of the illustrated in the embodiment Opening direction (to the right) opposite opening direction (to the left), the actuating gear 1 must also have an opposite installation direction.

As can already be seen from FIGS. 4 and 5, this can be achieved by first removing the base plate 79 from the housing 2, then removing the pinion 9 and the toothed piece 12 from the housing 2 and reinserting them together after turning and moving the pinion 9 will. Finally, the base plate 79 is then reassembled.

Of particular importance in this context is the design as an actuating gear 1 which can be switched by 180 °.
