EP0283659B1 - Door, window or the like with a wing made of metal or plastics profiles - Google Patents

Description

The invention relates to a window, a door or the like in which at least the sash frame is composed of metal or plastic profiles which have a guide channel which is open on one side but undercut on both sides in the cross-sectional direction and has a profiled guide channel for the longitudinally displaceable reception of a drive rod, wherein the drive rod located in the guide channel can be coupled from the open side thereof to an actuating gear, which is a drive member mounted in a housing and rotatably drivable by an operating handle, eg has a pinion, wherein the housing of the actuating gear is supported in front of the open side of the guide channel on the metal or plastic profile and can be fastened to it by screwing, and wherein the operating handle with a polygonal mandrel, for example a square or hexagonal mandrel, from the end face on the room side the sash frame is positively inserted through a hole in the metal or plastic profile into a correspondingly profiled driver recess of the drive element and is held in engagement with it by means of a screw connection.

From DE-PS 17 08 168 it is already part of the state of the art to use a fitting consisting of at least one drive rod and an actuating gear in the case of windows, doors or the like of the generic type, which also has the specified generic features.

A disadvantage of the known fitting, however, is that its actuating gear on the sash of the window, the door or the like must be installed overall on the rabbet side in front of the undercut profiled guide channel for the drive rod. Because the drive rod has to go through a relatively long travel path, for example between 35mm and 40mm, in order to fulfill the intended task in the undercut profiled guide channel and the angle of rotation for the operating handle of the actuating gear may not exceed 180, it is obvious that the diameter required for this the rotatably drivable drive member requires a relatively large installation space for the actuating gear in front of the folding surface of the wing containing the guide channel. The space required for the installation of the known actuating gear in front of the rebate surface of the casement containing the guide channel is at least 20 mm in the best case, but such a space is not regularly available in the form of metal or plastic profiles that are common today.

The invention is based on the object of specifying a window, a door or the like of the type described at the outset with the associated connecting rod fitting, which, in front of the folded surface of the sash frame having the undercut profiled guide channel, manages with an installation space for the actuating gear of the connecting rod fitting, as is readily available in conventional profile design. The free space required in front of the rebate surface of the wing for the installation of the actuating gear in the direction parallel to the wing plane should have a dimension of approximately 10 mm or should not significantly exceed this dimension.

This object is basically achieved by the characterizing features of claim 1, namely in that at least the metal and / or plastic profile of the sash frame is provided with an opening in the installation area of the actuating gear, that the opening on the sash frame covers the bottom of the guide channel in the metal and / or penetrates plastic profile,

that the housing section of the actuating gearbox supporting the drive member engages through the opening in the bottom of the guide channel, while only one housing section of the actuating gearbox which is in longitudinal engagement with the drive member is supported on the metal and / or plastic profile in front of the open side of the guide channel,

that the length of the notch in the drive rod is longer than the opening in the bottom of the guide channel on the metal and / or plastic profile by the maximum travel of the clutch slide,

that the clutch slide has rearward-facing driver projections at both ends, which protrude from a slot opening in the housing section of the actuating gear which guides it and which can be inserted into suitable driver recesses on the drive rod,

and that the housing section of the actuating gear which supports the drive member is provided on at least one side, but preferably on both sides, of the drive member with an engagement thread for fastening screws on a plane parallel to the direction of movement of the clutch slide and passing through the axis of rotation of the drive member,

which also reach through a bearing rosette for the operating handle that is supported on the end face of the casement on the room side.

These design measures of a generic window or a generic door or the like and the associated connecting rod fitting result in the advantage that without further metal or plastic profiles of a commercial type can be used, which have on their rebated surface a guide channel that is open on one side but undercut on both sides in the cross-sectional direction for longitudinally slidable mounting of drive rods, while on the other hand there is also the possibility of using commercially available operating handles, which in one Sit on the bearing rosette supported on the room-side end face of the casement. It is therefore avoided the use of structurally complex and therefore expensive handle gears, in which all the gear members required for the movement of the drive rod are accommodated in a housing which stores the operating handle and which must be mounted overall on the end face of the wing on the room side.

Although it is known, for example from DE-GM 71 08 093, for windows, doors or the like, in which at least the casement is composed of plastic profiles, to use connecting rod fittings in which the actuating gear has a breakthrough on the casement enforced, which is provided in the bottom of a directly molded guide channel. In this case, a commercially available operating handle can also interact with the actuating gear, which is held in a bearing rosette supported on the end face on the room side.

In this known window or door, however, the guide channel provided on the rebate surface of the casement in the plastic profile has the profile, which is generally customary in wooden windows, but is not undercut, and the actuation gear is direct in the manner customary for wooden window fittings As a standard, it is equipped with a drive rod, a cover rail that guides and covers it, as well as locking elements fastened to the drive rod and guided in the cover rail. It is a non-generic espagnolette fitting.

In a further embodiment of the invention it is provided according to claim 2 that the axis of rotation of the drive member and the engagement thread in the housing of the actuating gear lie on a plane which coincides at least approximately with half the thickness of the bottom wall of the guide channel on the metal and / or plastic profile. This ensures that after making the opening in the bottom of the guide channel, a support web for the gear housing formed by the bottom wall remains on the wing profile, which securely absorbs the clamping forces of the fastening screws acting on the gear housing for the bearing rosette of the rotary handle and counteracts undesired tilting of the actuating gear.

According to the invention it is also provided according to claim 3 that the hole for the passage of the polygonal mandrel on the operating handle and the holes for the passage of the fastening screws of the bearing rosette are holes which penetrate an undercut area of the guide channel until the opening in the bottom thereof.

These holes can be easily and securely made with a so-called multiple drilling or milling head and not only enable the operative connection between the operating handle and the actuating gear to be established in a simple manner, but also to determine the actuating gear on the casement.

For an optimal alignment of the actuating gear on the folded surface of the casement it is further provided according to the invention that the coupling slide housing section of the actuating gear has at least at its ends protruding claws which can be placed against the end face of the undercut guide channel profile sections of the casement .

In the case of windows, doors or the like of the generic type, it is common practice not to install the operating handle for the actuating gear on the sash at least during storage and transport of the windows or doors. This is because on the one hand the stackability of the window and door units is facilitated, but on the other hand also to avoid undesired damage to the operating handles. In order to nevertheless ensure the functionally correct installation position of the actuating gear on the wing, an inventive feature according to claim 5 also consists in the fact that the housing section of the actuating gear bearing the drive member has a coupling engagement for a plug socket on its side closest to the face end face of the wing frame with the axis of rotation of the drive member has, which can be engaged in this coupling engagement from the room-side end face of the casement through the aligned bore in the casement.

The coupling engagement can consist of a projecting neck, which can be encompassed by the socket and the socket can wear a collar which can be supported on the face end face of the casement. It has proven particularly useful to manufacture the socket from a plastic material which, on the one hand, fits snugly into the bore in the casement and, on the other hand, also fits the neck on the actuating gear with a snug fit.

Another feature of the invention is seen in claim 7 that the drive rod in the installation area of the actuating gear is provided with a notch, the length of which is at least longer than the length of the opening in the bottom of the guide channel on the metal and / or by the maximum travel of the clutch slide Plastic profile is dimensioned and that the notch in the drive rod has a width which is larger than the clear width of the opening side of the undercut guide channel in the casement, while the width of the opening in the bottom of the undercut guide channel is at most equal to the clear width of the opening side of the same is.

It has proven particularly useful if, according to claim 8, the notch in the drive rod is designed to be open on one side and the driver recesses are formed by transverse slots provided at a distance from the ends of the notch.

Finally, it also proves to be advantageous if, according to the invention, the bearing rosette of the operating handle engages, at least approximately fittingly, in the bores on the face-side end face of the casement frame with fixing pins integrally formed on the back concentrically with the axes of the fastening screws.

The object on which the invention is based can also be achieved according to claim 10 by providing two other essential features instead of the last partial marking feature proposed according to claim 1, namely,

that at least in the area of the housing section of the actuating gear which supports the drive member there are pairs of profile webs running parallel to the direction of movement of the clutch slide and projecting sideways from the housing, which each form a lower grip web and an overlap web for the edges of the undercut areas on the guide channel in the wing , and that at least in and or on one of the crossbars a clamping piece, for example a clamping screw is held and / or guided against an undercut area of the guide channel.

Even when using these essentials, the advantages mentioned above are fully retained.

According to the invention it is further proposed by claim 11 that the overlap webs of the profile web pairs each extend along the longitudinally movable housing section of the actuating gear, preferably over its entire length, while the lower webs are only on the housing section supporting the drive member.

It has been shown that this configuration ensures that the operating forces acting on the actuating gear are reliably introduced through the gear housing into the wing.

So that a secure holding engagement of the actuating gear with the wing can be brought about in a simple manner, the invention provides according to claim 12 that the distance of the facing away from each other, each delimited by a lower grip web and an overlap web outer surfaces between the pair of profile web pairs is than the distance between the mutually facing edges of the undercut areas on the guide channel of the wing and that the opening in the bottom of the wing-side guide channel has a width which is at least by the difference between these two distances greater than the maximum thickness of the housing area of the actuating gear which supports the drive member .

By using these measures, it is possible for the actuating gear to be brought into engagement with the one pair of profile webs at the edges of an undercut area after the insertion of its housing area supporting the drive member into the wing-side opening with a certain inclination of its plane against the wing plane and then so far to move sideways so that the opposite profile web pair can be placed at the level of the edges of the adjacent undercut area. If the actuating gear is then moved transversely to its plane in the opposite direction, then the second pair of profile webs also comes into engagement with the adjacent undercut region edges. Following this, the actuating gear can now be fixed by tightening the clamping pieces.

For safe handling of the actuating gear during the installation process, it has proven useful if, according to claim 13, the overlapping webs of the profile web pairs have a greater profile width than the lower grab webs, at least in the section of the housing area of the actuating gear that supports the drive member.

The same purpose is also useful if, according to claim 14, the smallest clear distance between the lower gripping bar and the overlap bar of the pair of profile webs equipped with the clamping piece is larger than the profile thickness of the undercut area edges on the guide channel, while the smallest clear distance between the lower crossbar and the crossover web of the other pair of profile webs corresponds approximately to the profile thickness of the undercut area edges on the guide channel.

Another design feature according to the invention aims at claim 15 that the housing section of the actuating gear bearing the drive member is offset on both sides in the longitudinal direction relative to the housing section guiding the clutch slide, to form a claw each, that the distance between the base surfaces of both claws is smaller than the length of the opening in the bottom of the wing-side guide channel is dimensioned, while the distance between the free ends of the two claws is adapted to the length of the opening.

The last-mentioned measure proves to be particularly recommendable if, according to claim 16, the claw sections of the housing section supporting the drive member on a plane parallel to the direction of movement of the clutch slide, through the axis of rotation of the drive member, at least on one side - but preferably on both sides - of the drive member with an engagement thread for fastening screws are provided which also reach through a bearing rosette for the operating handle which is supported on the end face of the casement on the room side. The result is a particularly stable holding connection of the actuating gear with the window and door sash.

Finally, the invention according to claim 17 also provides that the housing section of the actuating gear, which guides the clutch slide in a longitudinally movable manner, bears a locking rocker of a misuse lock, which is held under spring force and can be tilted about an axis lying parallel to its longitudinal direction and which has a locking leg which is equipped with locking Locking elements can be set in and out of blocking engagement on an extension of the coupling slide which projects from the housing section.

Of a window, a door or the like, which usually consists of a fixed frame and a sash, only a cutout area of the sash 1 that is essential for the present case is shown in FIGS. 1 to 3 of the drawing. The sash 1 is composed of metal and plastic profiles that are manufactured by extrusion or extrusion. Preferably, 1 light metal profiles are used for the production of the sash frame. The metal or plastic profiles used to form the sash frame 1 have a rollover 2 which is directed parallel to the sash plane and to which a fold section 3 is connected, essentially at a right angle. This fold section 3 is formed by a profile wall, a guide channel 5 which is open on one side but undercut on both sides in the cross-sectional direction being provided on the outside, the so-called fold surface 4. This guide channel 5 is delimited on both sides by a hook web 6, for example an L-shaped or angled profile, the two hook webs 6 with their free hook legs facing one another and delimiting the open longitudinal gap 7 of the guide channel 5, as clearly shown in FIGS. 2 and 3 can be removed. On the inside, the guide channel 5 is delimited by a base 8, which forms a section of the folded section 3 on the casement 1.

In the guide channel 5 on the casement 1, a drive rod 9 can be inserted in the longitudinal direction, which is shown in FIGS. 1 to 3 and 5 of the drawing.

An operating gear 10 is assigned to the casement 1 and the drive rod 9 which is accommodated in its guide channel 5 so as to be longitudinally movable, the essential features of which can be seen in FIGS. 1 to 3. In addition, an operating handle 11 with a bearing rosette 12 is also assigned to the casement 1 and the actuating gear 10 built into it, as indicated in FIG. 4 of the drawing.

The actuating gear 10 has a gear housing 13 which has a housing section 15 which supports a rotatable drive member, for example a pinion 14, and an adjoining housing section 16 in which a clutch slide 17 which meshes continuously with the pinion 14 is guided in a longitudinally movable manner.

In the direction of movement of the coupling slide 17, the housing section 16, which guides this longitudinally movably, projects by a considerable amount on opposite sides of the housing section 15 supporting the pinion 14, as can be clearly seen in FIG. 1.

An extension section 18 is connected to the housing section 15 supporting the pinion 14 on both sides, a threaded engagement 19 being formed in each of these extension sections 18.

The threaded engagements 19 have a common axis plane 20-20 with the axis of rotation 21 of the pinion 14 supported in the housing section 15, as can be seen in FIG. 1 of the drawing. This axis plane 20-20 lies parallel to the longitudinal direction of the housing section 16 of the gear housing 13, which guides the coupling slide 17 in a longitudinally movable manner.

The cantilevers 16a and 16b on both sides of the housing section 16 project beyond the extension section 18 of the housing section 15 by an amount that is dimensioned by a minimum larger than the maximum travel for the clutch slide 17 within the housing section 16. The clutch slide 17 has both ends a driver lug 17a or 17b, which is directed backwards and constantly protrudes from a slot opening in the housing section 16 of the actuating gear which guides it, as can be seen in FIG. 1.

1 also shows that the cross-sectional height 22 of the housing section 16 serving to guide the clutch slide 17 is dimensioned considerably smaller than the total cross-sectional height 23 of the transmission housing 13. Preferably, the cross-sectional height 22 of the housing section 16 should be at most one third of the total cross-sectional height 23 correspond to the gear housing 13 and amount to approximately 10 mm.

1 to 3 of the drawing it can still be seen that the housing section 16 of the actuating gear 13, which leads the clutch slide 17, has at least at its ends cantilevered support claws 24, which are preferably integrally formed on its arms 16a and 16b.

1 and 2 it can also be seen that the pinion 14 bearing housing section 15 of the actuating gear 13 carries on one side a projecting neck 25 aligned with the axis of rotation 21 of the pinion 14, which neck is expediently integrally formed on the gear housing 13 .

It has proven useful to assemble the gear housing 13 from two half shells that abut one another on the central plane of the pinion 14 that is normal to the axis of rotation 21. These can preferably be manufactured as molded parts from die-cast metal, only one of these half-shells being provided with the molded neck 25. Both half-shells are either screwed together or riveted or caulked after the pinion 14 and the clutch slide 17 have been inserted. Each of the two half-shells forms in one piece each half of the housing section 15 and half of the housing section 16 or the arms 16a and 16b of the gear housing 13.

As already stated above, a drive rod 9 is arranged in the undercut guide channel 5 of the casement 1 so as to be longitudinally slidable. This is inserted into the guide channel 5 in its longitudinal direction, as has also been mentioned above.

So that the drive rod 9 can be coupled to the driver lugs 17a and 17b when the actuating gear 10 is mounted on the wing 1, it is provided with driver recesses 26a and 26b, which are designed, for example, as transverse slots, as can be seen particularly in FIG. 5 .

The correct or functionally correct attachment of the actuating gear 10 to the casement 1 makes special precautions necessary. It is therefore necessary to provide the metal or plastic profile of the casement 1 on the bottom 8 of the guide channel 5 with an opening 27, for example with a notch or cutout, where the pinion 14 bearing section 15 of the gear housing 13 comes to rest (Fig. 2 to 4), the length 28 corresponds at least to the length of the housing section 15 plus the adjoining extension section 18. The width 29 of this opening 27 should be dimensioned somewhat larger than the thickness 30 of the housing section 15 and the extension section 18, but the slurry te of the open longitudinal gap 7 of the guide channel 5 does not exceed.

In the embodiment shown in the drawing, the width 29 of the opening 27 is dimensioned smaller than the width of the longitudinal gap 7 on the guide channel 5.

However, the installation of the actuating gear 10 in the sash frame 1 also requires that three holes 32 and 33a and 33b, for example as bores, be made from the end face 31 of the sash frame 1, the center axes of which have a common axis plane 34-34, which are different extends parallel to the longitudinal direction of the guide channel 5 and lies approximately at the center of the thickness of the bottom 8 to the guide channel 5, as can be seen in FIG. 1.

The formation of the holes 32 and 33a and 33b as bores makes it possible to produce them simultaneously with the aid of a so-called triple drilling or milling head. The drill or milling cutter for producing the hole 32 is designed in such a way that, with its maximum diameter, it cuts out a section 35 from the bottom 8 of the guide channel 5, which opens into the opening 27, as can be clearly seen in FIG. 4.

The drilling or milling tools for producing the holes 33a and 33b, on the other hand, are of stepped design, so that on the one hand they form only relatively narrow cutouts 36a and 36b in the bottom 8 of the guide channel 5 which open into the opening 27 (FIG. 4), at least slightly above the thickness of the room-side profile wall, however, make cutouts 37a and 37b, the width of which corresponds to the diameter of the holes 33a and 33b.

It can be seen from FIG. 2 that not only the bottom 8 of the guide channel 5 is cut away in the region of the hole 32, but rather also the hook web 6 adjacent to the rollover 2.

In the area of the holes 33a and 33b, however, the relevant hook web 6 is penetrated only in the section directed at right angles to the bottom 8, because in this area the drilling or milling tool has the reduced diameter for producing the cutouts 36a and 36b.

If the actuating gear 10 with its housing section 15 and the extension sections 18 is inserted from the rebate surface 4 into the opening 27, then the axis plane 20-20 comes into congruence with the axis plane 34-34, that is, the axis of rotation 21 of the pinion 14 is in the axial alignment position with the hole 32, while at the same time the threaded engagements 19 reach the holes 33a and 33b in the axial alignment. The neck 25 on the gear housing 10 then also assumes an axial alignment with the hole 32, whereby it comes to rest in the region of the cutout 35 and the hook web 6 broken therefrom, as indicated in FIG. 2 within the profile cross section to the casement by dash-dotted lines is. The cantilevers 16a and 16b of the gear housing 13 which form the housing section 16 come to rest with their support claws 24 on the end face of the mutually facing, free legs of the hook webs 6 and thus limit the insertion depth of the housing section 15 into the opening 27.

To secure the position of the operating mechanism 10 in its installed position on the sash frame 1, a socket 38 can now be inserted from the end face 31 of the sash frame 1 through the hole 32 in such a way that it includes the neck 25 on the gear housing 13 with a snug fit. Thus, the actuating gear 10 is already fixed in its correct installation position relative to the casement 1.

The socket 38 can expediently consist of plastic material and have a collar 39 with which it is supported in its inserted position on the room-side end face 21 of the casement 1. Also in the hole 32, the socket 38 should engage on its outer circumference as far as possible with a snug fit - possibly also elastically lockable.

Although it is entirely within the scope of the invention to interrupt the drive rod 9 in the installation area of the actuating gear 10 and to couple two drive rod sections 9a and 9b with the two driver lugs 17a and 17b of the clutch slide 17 via their driver recesses 26a and 26b designed as transverse slots it has proven particularly useful in practice if the drive rod 9 is made in one piece, that is to say a direct connection 9c between the two drive rod sections 9a and 9b is maintained.

For this purpose, the drive rod 9 is provided with a notch 44, the length 40 of which is dimensioned longer by the maximum travel of the clutch slide 17 in the actuating gear 10 than the length 28 of the opening 27 in the bottom 8 of the guide channel 5. The notch 44 in the drive rod 9 is open-sided in the embodiment shown, so that a connection 9c is only present on one longitudinal edge of the drive rod. Deviating from this, of course, measures can also be taken to limit the notch 44 on both longitudinal edges of the drive rod 9 by a connection 9c.

The windows and doors can be stored and transported in the installed position of the actuating gear 10 secured by the socket 38 without the operating handle 11 with its bearing rosette 12 being mounted on the casement 1. Only when needed, the operating handle 11 needs to be mounted on the casement 1 via its bearing rosette 12 and coupled to the pinion 14 of the actuating gear 10 via its polygonal mandrel 41. When the operating handle 11 is placed on the sash 1, its polygonal mandrel 41 first penetrates into the matching polygonal nut of the pinion 14. Subsequently, fixing pins 42 provided on the underside of the bearing rosette 12 reach into the holes 33a and 33b or the adjoining cutouts 37a and 37b for holding engagement and thus secure the bearing rosette 12 against undesired rotation.

Now only the fastening screws 43 need to be screwed into the threaded engagements 19 on the gear housing 13 through holes in the bearing rosette 12 in order to permanently ensure the interaction of the operating handle 11 with the actuating gear 10.

It should also be mentioned that the socket 38 for attaching the operating handle 11 and the bearing rosette 12 does not have to be removed because it is easily penetrated by the polygonal mandrel 41 and its support collar easily finds space in the free space on the underside of the bearing rosette 12.

In FIG. 6 of the drawing, of a window, a door or the like, which usually consists of a fixed frame and a casement, only the cutout area of the casement 51 that is essential for the present case can be seen.

The casement 51 is composed of metal or plastic profiles that have been produced by extrusion or extrusion. In particular, provision is made for the sash frame 51 to be made from light metal profiles which have a flap 52 directed parallel to the sash plane, to which a folding section 53 is connected, essentially at a right angle, as is the case on the one hand from FIG. 10 but on the other hand also 7 and 8 can be seen. This fold section 53 is formed by a profile wall, on the outside, the so-called fold surface 54, of a guide channel 55 which is open on one side but undercut on both sides in the cross-sectional direction is provided. The guide channel 55 is delimited on both sides by an L-shaped or angularly profiled hook web 56, the two hook webs 56 with their free hook legs facing one another and delimiting the open longitudinal gap 57 of the guide channel 55, as can be seen in FIGS. 7 to 9. On the inside, the guide channel 55 is delimited by a base 58, which forms part of the folded section 53 on the casement 51.

In the guide channel 55 on the sash 51 drive rods 59 can be inserted in the longitudinal direction, which are shown only schematically in Fig. 6 of the drawing.

An actuating gear 60 is assigned to the sash frame 51 and the drive rods 59 which are accommodated in its guide channel 55 so as to be longitudinally movable. In addition, the sash frame 51 and the actuating gear 60 built into it are also assigned an operating handle 61 indicated in FIG. 9 with a bearing rosette 62.

The actuating gear 60 has a gear housing 63 in which a rotatable drive member, for example a pinion 64, is mounted within a housing section 65. This is followed by a housing section 66, in which a coupling slide 67, which meshes continuously with the pinion 64, is guided in a longitudinally movable manner.

In the direction of movement of the coupling slide 67, the housing section 66, which guides this in a longitudinally movable manner, projects a considerable amount on opposite sides of the housing section 65 supporting the pinion 64 and forms cantilevers 66a and 66b on both sides, as can be clearly seen in FIG. 6.

The cantilevers 66a and 66b on both sides of the housing section 66 together have a length that is dimensioned by a minimum larger than the maximum travel for the clutch slide 67 within the housing section 66. The clutch slide 67 is provided on both ends with a driver attachment 67a and 67b, which is directed backwards and always protrudes from a slot opening in the housing section 66 of the actuating gear 60 leading it, as can be seen from FIG. 6.

6 can also be seen that the cross-sectional height 72 of the housing section 66 serving to guide the clutch slide 67 is considerably smaller than the overall cross-sectional height 73 of the gear housing 63. In the exemplary embodiment shown, the cross-sectional height 72 of the housing section 66 corresponds approximately to one Quarter of the total cross-sectional height 73 of the gear housing 63 and is at most 10 mm.

6 to 9 of the drawing show that on the gear housing 63 of the actuating gear 60 on both longitudinal sides parallel to the direction of movement of the clutch slide 67 and extending from the gear housing 63 laterally projecting profile web pairs 74 and 75 are provided, each having a lower gripping web 74a and 75a and form an overlap 74b and 75b.

While the lower gripping webs 74a and 75a are formed only in the region of the housing section 65 of the gear housing 63 supporting the pinion 64, the upper gripping webs 74b and 75b preferably extend over the entire length of the housing section 66 guiding the clutch slide 67.

The profile web pairs 74 and 75 are brought into operative connection and holding engagement with the edges on the free hook legs of the L-shaped or angularly profiled hook webs 56 which delimit the undercut guide channel 55 on the sash frame 51 in a manner which clearly shows the FIGS 7 and 9 can be seen in the drawing and will be explained in more detail below.

The gear housing 63 is preferably composed of two half shells abutting against each other on the central plane of the pinion 64, which is normal to the axis of rotation 71, and which are designed, for example, as molded parts made of die-cast metal. Both half-shells are either screwed together or riveted or caulked after the pinion 64 and the clutch slide 67 have been inserted. Each of the two half-shells forms in one piece in each case half of the housing section 65 and half of the housing section 66 or the arms 66a and 66b of the transmission housing 63.

It has already been mentioned above that the drive rods 59 are arranged to be longitudinally slidable in the undercut guide channel 55. They are inserted into the guide channel 55 in their longitudinal direction.

For the purpose of coupling the drive rods 9 with the driver lugs 67a and 67b of the clutch slide 67, these are provided with driver recesses 76a and 76b, which can be formed, for example, by transverse slots.

The correct or functionally correct attachment of the actuating gear 60 to the casement 51 requires special precautions. So it is necessary to provide the metal or plastic profile of the sash 51 on the bottom 58 of the guide channel 55 with an opening 77 where the pinion 64 bearing section 65 of the gear housing 63 lies, as is particularly the case in FIG. 7 , 8 and 10 can be removed. This opening 77 can be made as a notch or cut, the length 78 of which is adapted to the length of the housing section 65. The width 79 of the opening 77 is larger than the thickness 80a of the housing section 65 on the gear housing 63. However, it is also greater than the distance 80b between the housing section 66 in the region of the two profile web pairs 74 and 75 between the lower gripping webs 74a, 75a and the side flanks 74c and 75c delimiting the overlapping webs 74b, 75b from one another.

The width 79 of the opening 77 is preferably matched to the width of the longitudinal gap 57 between the mutually facing edges of the free hook legs of the L-shaped or angularly profiled hook webs 56 on the sash frame 51. The thickness 80c of the housing section 66 on the gear housing 63, measured over the outer flanks 74d and 75d of the lower gripping webs 74a and 75a of both profile web pairs 74 and 75, is in turn designed to a certain extent larger than the width 79 of the opening or the width of the longitudinal gap 57 in the guide channel 55 of the casement 51.

To install the actuating gear 50 in the casement 51, this is first inserted with its housing section 65 through the longitudinal gap 57 of the guide channel 55 into the opening 77. Then the entire actuating gear 30 is brought into an inclined position as shown in FIG. 7 of the drawing, so that the lower gripping bar 74a of the profile bar pair 74 below the longitudinal edge on the free hook leg of one of the L- or angularly profiled hooking bars 56 of the guide channel 55 can be moved. The entire gear housing 60 is then moved sideways until the flank 74c of the profile web pair 74 comes to rest at least approximately on the longitudinal edge of the hook web 56 in question. Now the gear housing 30 can be pivoted again into a parallel position to the level of the casement 51, the lower grip bar 75a of the other pair of profile bars 75 also passing the longitudinal edge of the associated hook bar 56 and coming to lie below the level of its free hook leg. Ultimately, the gear housing 60 is then shifted sideways so that the lower gripping bar 75a grips the longitudinal edge on the free hook leg of the other associated hooking bar 56, as can be seen from FIG. 8 of the drawing. The side flank 75c of the profile web pair 75 comes to rest against the longitudinal edge on the free hook leg of the hook web 56.

The overlap webs 74b and 75b of both profile web pairs 74 and 75 are in this case located on the outside of the free hook legs of both hook webs 56 of the guide channel 55 and serve primarily to limit the depth of engagement of the gear housing 50 within the casement 51. At least one overlap web 74b of the two Profile web pairs 74 and 75 are provided with a laterally projecting projection 81, which is equipped with a clamping piece, for example a clamping screw 82 held in a thread 83. The clamping piece, in particular the clamping screw 82, can against the the pair of profile webs 74 cooperating hook web 56 on the wing frame 51 are clamped, whereby the actuating gear 60 is fixed in its installed position on the wing frame 51, as shown in FIG. 8.

It is particularly advantageous if the clamping piece, for example the clamping screw 82, is effective in the area of the transverse plane of the actuating gear 60 which passes through the axis of rotation 71 of the pinion 64, because this then receives a symmetrical position fixation.

It is also advantageous if the overlapping webs 74b and 75b of the two profile web pairs 74 and 75 have a somewhat larger profile width than the associated undergripping webs 74a and 75a, at least over the length of the housing section 65. At least on the overlap web 75b of the profile web pair 75, a partial height of the side flanks 75c also adjoins the housing section 66 in such a way that their total length comes into lateral support contact with the longitudinal edge on the free hook leg of the associated hook web 56 and thereby causes an angular displacement of the actuating gear 60 counteracts reliably about the longitudinal axis of the tightened clamping screw 82.

So that the installation of the actuating gear 60 in the casement 1 can be carried out without any problems, it has proven to be important that the smallest clear distance between the lower gripping bar 74a and the gripping bar 74b of the pair of profile webs 74 equipped with the clamping piece, in particular the clamping screw 82 is dimensioned larger than the profile thickness of the free hook leg of the hook webs 56. In contrast, it is advantageous for a secure position fixation of the actuating gear 60 if the smallest clear distance between the lower gripping web 75a and the overlapping web 75b of the profile web pair 75 is approximately the profile thickness of the free one Hook leg corresponds to the hook webs 56.

It is hereby ensured that the portion of the flank 75c adjoining the overlap web 75b over the entire length of the housing section 66 on the underside with the adjacent longitudinal edge on the free hook leg of the hook web 56 remains in a form-fitting support engagement.

From FIG. 6 it can also be seen that the housing section 65 of the gear housing 63 which supports the pinion 64 is offset on both sides to form a claw 84a and 84b relative to the housing section 66 which guides the clutch slide 67. The distance between the base surfaces 85a and 85b of both claws 84a and 84b is dimensioned smaller than the length 78 of the opening 77 in the bottom 58 of the guide channel 55.

The claws 84a and 84b directly adjoin the underside of the housing section 66 or its extensions 66a and 66b, in such a way that their opening remains within the guide channel 55 when the actuating gear 60 is installed. On the other hand, the free end surfaces 86a and 86b of the claws 84a and 84b of the housing section 65 come into support engagement with the transverse edges of the opening 77 in the bottom 58 of the guide channel 55. In this way, longitudinal forces acting on the gear housing 63 of the actuating gear 60 are reliably introduced into the casement 51.

Within the guide channel 55, the ends of the drive rods 9, which are in engagement with the driver lugs 67a and 67b of the clutch slide 67, can be inserted into the claws 84a and 84b. This makes it possible to reduce the total length of the actuating gear 60 by an amount which corresponds to the common depth of both claws 84a and 84b.

In Fig. 11 of the drawing, an actuating gear 60 is shown, which differs from that of Fig. 6 basically only in that an extension section 88a or 88b is connected on both sides to the housing section 65 supporting the pinion 64, in each of which a thread engagement 89a or 89b is formed.

The thread engagements 89a and 89b here have a common axis plane 70-70 with the axis of rotation 71 of the pinion 64 supported in the housing section 65, as can be clearly seen from FIG. 10. This axis plane 70-70 lies parallel to the longitudinal direction of the housing section 66 of the gear housing 63, which longitudinally moves the coupling slide 67.

6, when using the actuating gear 60 according to FIG. 6, the fastening screws 90 for the bearing escutcheon 62 of the operating handle 61 are brought into engagement in threaded bushes 91, which are connected directly to the sash frame 51 as so-called rivet nuts, according to FIG. 10 these fastening screws 90 can be used directly are screwed into the threaded engagements 89a, 89b on the gear housing 63 in order to permanently ensure the interaction of the operating handle 61 with the actuating gear 60.

In any case, the drive connection between the operating handle 61 and the pinion 64 of the actuating gear 60 is effected via a polygonal mandrel, in particular a square mandrel 92, which engages with a correspondingly profiled polygonal nut of the pinion 64.

From the drawing it can still be seen that the longitudinally movable housing section 66 of the actuating gear leading the clutch slide 67 60 can also carry a locking rocker 94, which can be tilted about an axis 93 lying parallel to its longitudinal direction, for an incorrect operation lock. This locking rocker 94 has an actuating arm 95 which, with a claw-shaped bearing arm 96, swivels around a bearing bead 97 fixed to the housing.

At the other end of the actuating arm 95 of the locking rocker 94 there is a connecting arm 98, which in turn carries at its free end an angled locking arm 99 which extends at an acute angle to the actuating arm 95.

Via the locking leg 99, the locking rocker 94 interacts with locking locking elements 100 on the underside of a bracket 101 protruding from the housing section 66. The locking rocker 94 is under the action of a helical compression spring 102 which is supported on the housing section 66 and which tries to keep the locking leg 99 with the locking locking elements 100 in locking engagement. This is always the case when the sash 1 is brought into an open position relative to the fixed frame. If, on the other hand, the casement 51 reaches the closed position relative to the fixed frame, then the actuating leg 95 of the locking rocker 94 interacts with an actuating stop on the fixed frame. This then moves the locking rocker 94 against the force of the helical compression spring 102 in such a position that its locking leg 99 with the locking locking elements 100 on the boom 101 comes out of blocking engagement. Only then can the clutch slide 67 of the actuating gear 60 be moved into the desired switching position by rotating the pinion 64.

Finally, it should also be emphasized that, instead of the clamping screw 82, clamping parts can also be used as a clamping piece for fixing the actuating gear 60 on the sash frame 51, said clamping parts being driven, for example, between the overlap web 74b and the hook web 56.
