Description

Die Erfindung betrifft ein Getriebe gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a transmission according to the preamble of claim 1.

Ein derartiges Getriebe wird im vorveröffentlichen Prospekt der Anmelderin "Beschläge für Aluminium-Fenster und -Fenstertüren", Form 6 318 67 915, dargestellt. Dieses Getriebe ist für eine Anordnung innerhalb eines Falzes eines Rahmenteils des Flügelrahmens vorgesehen. Dementsprechend muß der genannte Falz einen großen Querschnitt haben, d. h., bei der Konstruktion der Rahmenprofile sind die Einbaumaße des Getriebes zu berücksichtigen, welches dementsprechend nur mit besonderen Rahmen kombiniert werden kann.Such a gear is shown in the applicant's pre-published prospectus "Fittings for aluminum windows and french doors", form 6 318 67 915. This gear is intended for an arrangement within a fold of a frame part of the casement. Accordingly, the said fold must have a large cross-section, i. In other words, when installing the frame profiles, the installation dimensions of the gear unit must be taken into account, which can therefore only be combined with special frames.

Aufgabe der Erfindung ist es, ein Getriebe der eingangs genannten Art so auszubilden, daß es bei kompakter Bauweise an beliebigen Rahmen angeordnet werden kann.The object of the invention is to design a transmission of the type mentioned in such a way that it can be arranged on any frame with a compact design.

Diese Aufgabe wird durch die Ausgestaltung gemäß Anspruch 1 gelöst. Damit sieht die Erfindung vor, daß die Überlastkupplung in der knaufartigen Handhabe angeordnet ist, so daß der Einbau unabhängig von den Abmessungen des Falzes ermöglicht wird. Die besondere Ausgestaltung der Überlastkupplung schafft die Möglichkeit für die Integration der Kupplung in der Handhabe in kompakter Form mit relativ wenig notwendigen Funktionsteilen. Der Raum innerhalb der Handhabe wird optimal genutzt.This object is achieved by the configuration according to claim 1. Thus, the invention provides that the overload clutch is arranged in the knob-like handle, so that the installation is possible regardless of the dimensions of the fold. The special design of the overload clutch creates the possibility of integrating the clutch in the handle in a compact form with relatively few necessary functional parts. The space within the handle is optimally used.

Bei der erfindungsgemäßen Anordnung der Funktionsteile ist die radiale Lage der Rast- und Gegenrastelemente unabhängig von der Größe des Zahnrads. Damit kann ein relativ kleines Zahnrad eingesetzt werden, so daß das auf dem Flügel aufliegend montierte Gehäuse ebenfalls kleine Abmessungen erhalten kann. Die Rastelemente können nun radial relativ weit außen in der knaufartigen Handhabe angeordnet werden, ohne daß ein größeres Zahnrad und eine stärkere Rastfeder erforderlich werden.In the arrangement of the functional parts according to the invention, the radial position of the locking and counter-locking elements is independent of the size of the gear. This allows a relatively small gearwheel to be used, so that the housing mounted on the wing can also have small dimensions. The locking elements can now be arranged radially relatively far outside in the knob-like handle without the need for a larger gear and a stronger locking spring.

Das Gehäuse braucht im wesentlichen lediglich zur Verkleidung der Spindel bemessen zu sein und kann damit ein leistenartig flaches Aussehen erhalten. Die knaufartige Handhabe kann außer zur Betätigung des Getriebes auch als Griff bei der Drehöffnung des Flügels dienen, etwa beim Reinigen des Fensters. Damit erübrigen sich gesondert zu montierende Handgriffe am Flügel, wie sie im Zusammenhang mit bekannten Drehkippbeschlägen üblicherweise angeordnet werden.The housing essentially only needs to be dimensioned to cover the spindle and can thus have a strip-like flat appearance. The knob-like handle can also serve as a handle for the opening of the sash in addition to actuating the gear, for example when cleaning the window. This eliminates the need for separately mounted handles on the sash, as are usually arranged in connection with known turn-tilt fittings.

Schließlich begünstigt die Konstruktion auch eine Anordnung mit abnehmbarer Handhabe, um ein unbefugtes Verstellen des Fensters oder dgl. gegebenenfalls durch Entfernen der Handhabe zu erschweren.Finally, the construction also favors an arrangement with a removable handle in order to make unauthorized adjustment of the window or the like difficult, if necessary by removing the handle.

Hohe Funktionssicherheit bei besonders kompaktem Aufbau wird erhalten, wenn das die Hülse umgebende Plattenteil als ringförmiges Plattenteil ausgebildet ist, das über Stegteile, welche im Achsteil angeordnete Axialabschnitte durchsetzen, mit dem die SchraubenfederHigh functional reliability with a particularly compact structure is obtained if the plate part surrounding the sleeve is designed as an annular plate part, with which the coil spring passes through web parts which pass through axial sections arranged in the axle part

abstützenden Plattenteil verbunden ist.supporting plate part is connected.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist an der knaufartigen Handhabe eine ausklappbare Kurbel angeordnet, welche die Betätigung der Handhabe erleichtert, wenn eine größere Verstellung des Flügels vorgenommen werden soll. Bei kleineren Korrekturen der eingestellten Lage des Flügels kann jedoch die-Handhabe, ohne die Kurbel auszuklappen, unmittelbar betätigt werden. Dabei ist vorteilhaft, wenn der Griff der eingeklappten Kurbel, etwa auf der dem Flügel zugewandten Seite der knaufartigen Handhabe, etwas aus derselben heraussteht, um ein Abgleiten der den Knauf betätigenden Hand zu verhindern.According to a preferred embodiment of the invention, a fold-out crank is arranged on the knob-like handle, which facilitates the operation of the handle when a larger adjustment of the wing is to be carried out. In the event of minor corrections to the set position of the sash, however, the handle can be actuated immediately without unfolding the crank. It is advantageous if the handle of the folded crank, for example on the side of the knob-like handle facing the wing, protrudes somewhat from the latter in order to prevent the hand actuating the knob from sliding off.

Wenn die knaufartige Handhabe mit zum Tür- bzw. Fenstermittenbereich hin geneigter Drehachse angeordnet ist, derart, daß die Kontur der knaufartigen Handhabe bei Ansicht senkrecht zur Fenster- bzw. Türebene auf der zum Tür- bzw. Fenstermittenbereich weisenden Seite des vom Tür- bzw. Fenstermittenbereiches abgewandten Randes des Gehäuses angeordnet ist, läßt sich das Getriebe auch besonders nahe am Außenrand des Tür- bzw. Fensterrahmens sowie in an den Rahmen anschließenden Eckbereichen anordnen.If the knob-like handle is arranged with the axis of rotation inclined towards the door or window center area, such that the contour of the knob-like handle when viewed perpendicular to the window or door plane on the side facing the door or window center area from the door or Edge of the housing facing away from the center of the window, the gear can also be arranged particularly close to the outer edge of the door or window frame and in corner areas adjoining the frame.

Die knaufartige Handhabe ist bevorzugt stirnseitig der Spindel am einen Ende des Gehäuses, d.h. unsymmetrisch angeordnet, so daß der Knauf beispielsweise bei bevorzugt vorgesehener Montage des Gehäuses an einem horizontalen Rahmenteil des Flügels nahe einer von der Drehachse desselben entfernten Rahmenecke praktisch unmittelbar an der genannten Rahmenecke angebracht werden kann, so daß eine eventuelle Drehöffnung des Flügels, bei der die Handhabe als Griff benutzt wird, erleichtert ist.The knob-like handle is preferably on the face of the spindle at one end of the housing, i.e. arranged asymmetrically, so that the knob can be attached practically directly to the said frame corner, for example when the housing is preferably mounted on a horizontal frame part of the wing near a frame corner distant from the axis of rotation thereof, so that a possible pivot opening of the wing, in which the handle used as a handle is relieved.

Im übrigen ist eine entsprechende Anordnung des Getriebes auch an einem vertikalen Rahmenteil des Flügels möglich und vorteilhaft, weil in diesem Falle gegebenenfalls um die der knaufartigen Handhabe benachbarte Rahmenecke herumgeführte Stellgestängeteile erübrigt werden.In addition, a corresponding arrangement of the transmission is also possible and advantageous on a vertical frame part of the sash, because in this case, the linkage parts that are guided around the corner of the frame adjacent to the knob-like handle may be dispensed with.

Als Rastelemente sind bevorzugt Rastaussparungen angeordnet, welche mit Kugeln zusammenwirken, die in Aussparungen eines kugelkäfigartigen Ringteiles angeordnet sind, welches seinerseits undrehbar in der Handhabe angeordnet ist.As locking elements, locking recesses are preferably arranged, which interact with balls, which are arranged in recesses of a ball-cage-like ring part, which in turn is arranged non-rotatably in the handle.

Bei dieser Anordnung können die Kugeln gegen eine Gegendruckplatte gespannt sein, die auf dem Achsteil als Axialsicherung der Handhabe gehaltert ist. Muß die Rastvorrichtung auslösen, etwa wenn die Handhabe mit hinreichender Kraft weitergedreht wird, obwohl der Flügel eine Endlage erreicht hat, so wirken die Kugeln mit der Gegendruckplatte sowie dem ringförmigen Bereich des Plattenteiles nach Art eines Kugelaxiallagers zusammen, wobei nur geringe Gleitreibung auftritt, da die Kugeln auf der Gegendruckplatte bzw. dem ringförmigen Bereich des Plattenteiles abrollen. Dementsprechend wird der Rastwiderstand der Rastvorrichtung durch Reibung nur wenig beeinflußt und überwiegend durch die Spannung der Rastfeder vorgegeben.In this arrangement, the balls can be clamped against a counterpressure plate which is held on the axle part as an axial securing device for the handle. If the locking device has to be triggered, for example if the handle is turned with sufficient force even though the sash has reached an end position, the balls interact with the counterpressure plate and the annular area of the plate part in the manner of a ball thrust bearing, with only slight sliding friction occurring as the Roll balls on the counterpressure plate or the annular area of the plate part. Accordingly, the latching resistance of the latching device is only slightly influenced by friction and is predominantly determined by the tension of the latching spring.

Das weitere Zahnrad kann mittels einer es durchsetzenden Mittelbohrung auf einem im Gehäuseteil angeordneten Bolzen sowie auf seiner dem Achsteil zugewandten Seite mittels einer kreisförmigen Verdickung in einer Gehäusebohrung radial drehgelagert sein, um so dem Achsteil sowie der darauf angeordneten knaufartigen Handhabe eine großflächige und stabile Abstützung am Gehäuse zu vermitteln.The further gear wheel can be rotatably supported by means of a central bore passing through it on a bolt arranged in the housing part and on its side facing the axle part by means of a circular thickening in a housing bore, in order to provide the axle part and the knob-like handle arranged thereon with a large and stable support on the housing to convey.

Weitere vorteilhafte Merkmale der Erfindung sind Gegenstand der Ansprüche und werden nachfolgend anhand der Zeichnung erläutert, in der eine besonders bevorzugte Ausführungsform der Erfindung dargestellt ist. Dabei zeigt

  • Fig. 2 eine Seitenansicht desselben entsprechend dem Pfeil in Fig. 1 und
  • Fig. 3 ein Schnittbild des Gehäuses sowie der knaufartigen Handhabe in einer die Achse der Handhabe enthaltenden Querebene des Gehäuses.
Further advantageous features of the invention are the subject of the claims and are explained below with reference to the drawing, in which a particularly preferred embodiment of the invention is shown. It shows
  • 1 is a plan view of the housing,
  • Fig. 2 is a side view of the same according to the arrow in Fig. 1 and
  • Fig. 3 is a sectional view of the housing and the knob-like handle in a transverse plane of the housing containing the axis of the handle.

Ein leistenartig flaches Gehäuse 1, welches auf einem Rahmenteil des Tür- bzw. Fensterflügels, gegebenenfalls auch auf einem feststehenden Rahmenteil montiert ist, ist in Gehäuselängsrichtung eine Spindel 2 angeordnet, auf der ein durch Drehung der Spindel verschiebbares Schieberteil 3 angeordnet ist, welches zum Antrieb nicht dargestellter Stellgestänge und damit antriebsmäßig gekoppelter Ausstellscheren des Flügels dient und in gehäusefesten Führungen gleitgeführt ist.A strip-like flat housing 1, which is mounted on a frame part of the door or window sash, possibly also on a fixed frame part, a spindle 2 is arranged in the longitudinal direction of the housing, on which a slide part 3 which is displaceable by rotation of the spindle is arranged and which drives the drive Serving linkage, not shown, and thus drive-coupled scissors of the wing is used and is slidably guided in guides.

Zum Antrieb der Spindel 2 dient eine knaufartige Handhabe 4, die stirnseitig der Spindel 2 am einen, dachartigen Querschnitt aufweisenden Endbereich des Gehäuses 1 mit zum Flügelmittenbereich hin geneigter Achse angeordnet ist und mit einem gleichachsig zur Handhabe 4 angeordneten Kegelzahnrad 5 gekoppelt ist, welches mit einem am zugewandten Stirnende der Spindel 2 angeordnetem Kegelzahnrad 6 kämmt.A spindle-like handle 4 is used to drive the spindle 2, which is arranged on the end face of the spindle 2 on an end region of the housing 1 with a roof-like cross section and has an inclined axis toward the wing center region and is coupled to a bevel gear 5 which is arranged coaxially with the handle 4 and which is coupled to a on the facing end of the spindle 2 arranged bevel gear 6 meshes.

An der Handhabe 4 ist eine in Pfeilrichtung P ausklappbare Kurbel 7 angeordnet, welche die Betätigung der Handhabe 4, insbesondere wenn die Handhabe 4 mehrfach gedreht werden soll, erleichtert. Gegebenenfalls kann aber die Handhabe 4 auch, insbesondere bei Verstellung um relativ kleine Winkel, unmittelbar bei eingeklappter Kurbel 7 betätigt werden, wobei der Griff 7' der Kurbel 7, welcher auf der der Flügelebene zugewandten Seite der Handhabe 4 herausragt, ein Abrutschen der die knaufartige Handhabe 4 betätigenden Hand verhindert.A crank 7, which can be folded out in the direction of the arrow P, is arranged on the handle 4, which facilitates the operation of the handle 4, in particular if the handle 4 is to be rotated several times. If necessary, however, the handle 4 can also be actuated, especially when adjusted by a relatively small angle, directly when the crank 7 is folded in, the handle 7 ′ of the crank 7, which protrudes on the side of the handle 4 facing the wing plane, from slipping off the knob-like Handle 4 operating hand prevented.

Das Kegelzahnrad 5 setzt sich in ein Achsteil 8 fort, welches zusammen mit dem Kegelzahnrad 5 als hülsenförmiges Teil ausgebildet ist. Zwischen dem Kegelzahnrad 5 und dem Achsteil 8 ist eine ringförmige Verdickung 9 angeordnet. Diese Verdickung 9 dient dazu, eine das Kegelzahnrad 5 aufnehmende Gehäusebohrung 10 nach außen abzudichten, wobei die Verdickung 9 auch zur radialen Lagerung des Kegelzahnrades 5 in der Gehäusebohrung 10 beiträgt.The bevel gear 5 continues in an axle part 8, which is designed together with the bevel gear 5 as a sleeve-shaped part. An annular thickening 9 is arranged between the bevel gear 5 and the axle part 8. This thickening 9 serves to seal a housing bore 10 receiving the bevel gear 5 to the outside, the thickening 9 also contributing to the radial mounting of the bevel gear 5 in the housing bore 10.

Um ein Zusammenwirken der Kegelzahnräder 5 und 6 zu ermöglichen, besitzt die Gehäusebohrung 10 eine in der Zeichnung nicht sichtbare Öffnung im Bereich ihrer Umfangswandung.In order to enable the bevel gears 5 and 6 to cooperate, the housing bore 10 has an opening in the region of its peripheral wall which is not visible in the drawing.

Im übrigen setzt sich die Gehäusebohrung 10 in eine gleichachsig angeordnete weitere Bohrung 11 mit geringerem Durchmesser fort.Otherwise, the housing bore 10 continues into a coaxial bore 11 with a smaller diameter.

Die zuletzt genannte Bohrung 11 dient zur Anordnung eines Bolzenteiles 12, welches mit einer Mutter 13 in einem erweiterten Endbereich der Bohrung 11 derart verschraubt ist, daß ein dickerer Schaftbereich 12' des Bolzenteiles 12 fest gegen ein Ringteil 14 gespannt wird, welches in einer ringstufenartigen Ausnehmung im Übergangsbereich zwischen der Gehäusebohrung 10 und der weiteren Bohrung 11 angeordnet ist. Der erweiterte Schaftbereich 12' des Bolzenteiles 12 durchsetzt eine Axialbohrung des Kegelzahnrades 5 und dient zu dessen Radiallagerung, während das Ringteil 14 und der Kopf 12" des Bolzenteilel 12 als Axiallager des Kegelzahnrades 5 zusammenwirken.The last-mentioned bore 11 is used to arrange a bolt part 12 which is screwed to a nut 13 in an enlarged end region of the bore 11 in such a way that a thicker shaft region 12 'of the bolt part 12 is firmly clamped against a ring part 14 which is in an annular step-like recess is arranged in the transition region between the housing bore 10 and the further bore 11. The enlarged shaft region 12 'of the bolt part 12 passes through an axial bore of the bevel gear 5 and serves for its radial bearing, while the ring part 14 and the head 12 "of the bolt part 12 cooperate as an axial bearing of the bevel gear 5.

Innerhalb der vom Kegelzahnrad 5 und dem Achsteil 8 gebildeten Hülse ist eine Schraubenfeder 15 angeordnet, welche sich mit ihrem dem Kegelzahnrad 5 zugewandten Ende auf einer Ringstufe innerhalb der Hülse abstützt und mit ihrem anderen Ende gegen ein Plattenteil 16 gespannt ist. Dieses Plattenteil 16 besteht aus einem das bewegliche Federwiderlager der Schraubenfeder 15 bildenden inneren Plattenteil 16' sowie einem ringförmigen äußeren Plattenteil 16", welches innerhalb einer kreisförmigen Querschnitt aufweisenden Ausnehmung 17 der auf dem Achsteil 8 radial gelagerten knaufartigen Handhabe 4 angeordnet ist. Inneres und äußeres Plattenteil 16' bzw. 16" sind miteinander über Stege verbunden, welche axiale, zum freien Ende des Achsteiles 8 hin offene Schlitze 18 durchsetzen. Damit ist das Plattenteil 16 gegenüber dem Achsteil 8 undrehbar, jedoch axial verschiebbar angeordnet.A helical spring 15 is arranged within the sleeve formed by the bevel gear 5 and the axle part 8, which is supported with its end facing the bevel gear 5 on an annular step within the sleeve and is tensioned against a plate part 16 with its other end. This plate part 16 consists of an inner plate part 16 'forming the movable spring abutment of the helical spring 15 and an annular outer plate part 16 "which is arranged within a circular cross-section recess 17 of the knob-like handle 4 radially mounted on the axis part 8. Inner and outer plate part 16 ′ and 16 ″ are connected to one another via webs which pass through axial slots 18 which are open towards the free end of the axle part 8. Thus, the plate part 16 is non-rotatable relative to the axis part 8, but axially displaceable.

Im äußeren Plattenteil 16" sind rastartige Vertiefungen bzw. Radialschlitze 19 angeordnet, welche mit Rastkugeln 20 zusammenwirken. Diese Rastkugeln 20 werden vom Plattenteil 16 unter der Spannung der Schraubenfeder 15 gegen eine ringförmige Gegendruckplatte 21 geschoben, welche am freien Ende des Achsteiles 8 befestigt ist und mit einer Ringstufe am Übergang des Achsteiles 8 zur ringförmigen Verdickung 9 zur Axiallagerung der knaufförmigen Handhabe 4 zusammenwirkt.Latch-like depressions or radial slots 19 are arranged in the outer plate part 16 ″, which cooperate with latching balls 20. These latching balls 20 are pushed by the plate part 16 under the tension of the coil spring 15 against an annular counter-pressure plate 21 which is fastened to the free end of the axle part 8 and interacts with a ring step at the transition of the axle part 8 to the annular thickening 9 for the axial bearing of the knob-shaped handle 4.

Zwischen dem Plattenteil 16 und der Gegendruckplatte 21 ist auf dem Achsteil 8 ein aus zwei Blechen zusammengesetztes Ringteil 22 drehbar gelagert, welches die Rastkugeln 20 nach Art eines Kugelkäfiges in nach radial auswärts geöffneten Schlitzen 22' aufnimmt. Am Ringteil 22 sind über dessen Umfang vorstehende Radialfortsätze 23 angeordnet, welche in zugeordnete Axialschlitze in der Umfangswandung der Ausnehmung 17 der knaufartigen Handhabe 4 hineinragen, derart, daß das Ringteil 22 und die knaufartige Handhabe 4 relativ zueinander undrehbar miteinander gekoppelt sind.Between the plate part 16 and the counter-pressure plate 21, a ring part 22 composed of two sheets is rotatably mounted on the axle part 8 and radially engages the locking balls 20 in the manner of a ball cage receives outwardly open slots 22 '. On the ring part 22 projecting radial projections 23 are arranged over its circumference, which protrude into associated axial slots in the peripheral wall of the recess 17 of the knob-like handle 4, such that the ring part 22 and the knob-like handle 4 are non-rotatably coupled to one another.

Befinden sich die Rastkugeln 20, wie in Fig. 3 dargestellt ist, innerhalb der Rastausnehmungen bzw. Radialschlitze 19 des Plattenteiles 16, so ist die knaufartige Handhabe 4 über das mit ihr undrehbar gekoppelte kugelkäfigartige Ringteil 22, die Rastkugeln 20 sowie das gegenüber dem Achsteil 8 undrehbare Plattenteil 16 mit dem Achsteil 8 sowie dem daran angeordneten Kegelzahnrad 5 verrastet, so daß das Kegelzahnrad 5 bei Drehung der Handhabe 4 mitgedreht wird und über das Kegelzahnrad 6 die Spindel 2 antreibt.If the locking balls 20, as shown in FIG. 3, are located within the locking recesses or radial slots 19 of the plate part 16, then the knob-like handle 4 is above the ball cage-like ring part 22, which is non-rotatably coupled to it, the locking balls 20 and that relative to the axle part 8 non-rotatable plate part 16 with the axle part 8 and the bevel gear 5 arranged thereon locked, so that the bevel gear 5 is rotated when the handle 4 is rotated and drives the spindle 2 via the bevel gear 6.

Bei übermäßiger Belastung, etwa wenn der Tür- bzw. Fensterflügel eine Endlage erreicht hat und die Handhabe 4 gleichwohl in Richtung dieser Endlage weitergedreht wird, so kann das Plattenteil 16 gegen die Spannung der Feder 15 ausweichen, so daß die Rastkugeln 20 nicht mehr mit den Rastausnehmungen bzw. Radialschlitzen 19 im Plattenteil 16 zusammenwirken und die Verrastung aufgehoben ist.With excessive load, such as when the door or window sash has reached an end position and the handle 4 is nevertheless rotated towards this end position, the plate member 16 can deflect against the tension of the spring 15, so that the locking balls 20 no longer with the Interlocking recesses or radial slots 19 cooperate in the plate part 16 and the locking is released.

Somit wird vermieden, daß bei unsachgemäßer Betätigung der Handhabe 4 auf das mit dem Schieberteil 3 gekoppelte Stellgestänge des Tür- bzw. Fensterflügels unzulässig hohe Stellkräfte ausgeübt werden, welche zur Zerstörung von Beschlagteilen führen könnten.It is thus avoided that inadvertently high actuating forces are exerted on the actuating linkage of the door or window sash coupled to the slide part 3 if the handle 4 is operated improperly, which could lead to the destruction of hardware components.

Wie aus den Figuren 1 und 2 ersichtlich ist, besitzt das Gehäuse 1 eine Verkleidung 24 mit einem Sichtfenster 25, durch das die Stellung des Schieberteiles 3 erkennbar ist. Auf dem Sichtfenster 25 angeordnete Symbole geben dabei sinngemäß die jeweils zugeordnete Stellung des betätigten Flügels wieder.As can be seen from FIGS. 1 and 2, the housing 1 has a cladding 24 with a viewing window 25 through which the position of the slide part 3 can be seen. Symbols arranged on the viewing window 25 represent the corresponding assigned position of the actuated wing.

Am einen Ende wird die Verkleidung 24 am Gehäuse 1 festgehalten, indem eine an der Verkleidung 24 angeordnete stufenförmige Abwinklung 26 eine entsprechende Aussparung am Gehäuse 1 untergreift. Am anderen Ende besitzt die Verkleidung 24 eine gleichartige stufenförmige Abwinklung 27, welche mit der Nase eines schieberartigen Haltegliedes 28 zusammenwirkt. Das schieberartige Halteglied 28 kann mittels einer Stellschraube 29, die über eine Öffnung 30 in der Verkleidung 24 zugänglich ist, verstellt werden. Die Stellschraube 29 greift in eine Bohrung am Gehäuse 1 ein, welche mit der das Bolzenteil 12 aufnehmenden Bohrung 11 verbunden ist. Dadurch stützt sich die Stellschraube 29 bei von innen gegen die Verkleidung 24 gespanntem Halteglied 28 auf dem Bolzenteil 12 ab und wirkt damit zusätzlich als Verdrehsicherung für das Bolzenteil 12. Insgesamt zeichnet sich das erfindungsgemäße Getriebe durch außerordentlich kompakte Bauweise aus, da das Gehäuse 1 im wesentlichen nur die Spindel 2 sowie das Schieberteil 3 aufnehmen muß und alle übrigen Elemente in bzw. an der knaufartigen Handhabe 4 angeordnet sind.The cladding 24 is held on the housing 1 at one end by a step-shaped bend 26 arranged on the cladding 24 engaging under a corresponding recess on the housing 1. At the other end, the covering 24 has a similar stepped bend 27, which interacts with the nose of a slide-like holding member 28. The slide-like holding member 28 can be adjusted by means of an adjusting screw 29 which is accessible via an opening 30 in the casing 24. The set screw 29 engages in a bore in the housing 1, which is connected to the bore 11 receiving the bolt part 12. As a result, the set screw 29 is supported on the bolt part 12 when the holding member 28 is tensioned from the inside against the cladding 24 and thus additionally acts as an anti-rotation device for the bolt part 12. Overall, the transmission according to the invention is characterized by an extremely compact design, since the housing 1 essentially only the spindle 2 and the slide part 3 have to accommodate and all other elements are arranged in or on the knob-like handle 4.

Dabei wird durch die zur Flügelebene geneigte Lage der Handhabe 4 erreicht, daß deren Umfang auf der dem Rahmenmittenbereich zugewandten Seite der vom Rahmenmittenbereich abgewandten, in Fig. 3 unteren Seite des Gehäuses 1 angeordnet ist. Dementsprechend kann das erfindungsgemäße Getriebe bei Bedarf auch in Eckbereichen untergebracht werden, die durch die Rahmenebene sowie an den Tür- bzw. Fensterrahmen anschließende Bauwerksteile gebildet werden.The position of the handle 4 inclined to the sash plane ensures that its circumference is arranged on the side of the housing 1 facing away from the frame center region, the lower side of the housing 1 in FIG. 3, facing the frame center region. Accordingly, the transmission according to the invention can, if required, also be accommodated in corner areas which are formed by the frame level and structural parts adjoining the door or window frame.
