Definitions
- the present invention relates to a fitting for windows, doors or the like, with a transmission, which has a rotatably mounted for switching the fitting about a first axis of rotation input element and a coupled to a first drive rod or couplable, displaceable first output element.
- Such fittings are used for example as so-called edge seals in rabbet grooves of a wing of the window, the door or the like.
- the input member is rotated by means of an actuator such as a handle.
- the transmission converts this rotational movement into a displacement movement of a drive rod, which in turn causes the locking or unlocking of the wing.
- the implementation of the rotational movement takes place in a sliding movement by an arrangement of pinion and rack. That the input member may be formed as a pinion, which meshes with a rack driving the drive rod.
- the invention has for its object to provide a fitting of the type mentioned, which takes up less space.
- a displaceable transmission element for converting a rotational movement of the input element into a displacement movement of the first output element, which is drivable by rotating the input element to a sliding movement, wherein in or on the displaceable transmission element, a first intermediate gear is rotatably mounted, which with a first, fixed to the housing Rack section and with a second, provided on the first output member rack section meshes.
- the conversion of a rotary movement of the input element into a displacement movement of the transmission element may be e.g. be effected in that the input element is designed as a gear and meshes with a rack portion of the transmission element.
- the intermediate gear mounted in or on the transmission element rolls off the toothed rack section fixed to the housing and drives the first output element into a sliding movement via the second rack section at.
- the stroke of the first output element relative to a housing-fixed reference point is composed here of the displacement of the axis of rotation of the intermediate gear on the one hand and from the caused by the rolling movement of the intermediate gear propulsion of the second rack portion relative to the axis of rotation of the idler gear on the other.
- the stroke of the transmission element is thus translated into an enlarged stroke of the first output element in a manner similar to that of a planetary gear.
- the stroke of the first output element relative to the stroke of the transmission element can thereby be doubled.
- a fitting can be provided with a rear mandrel dimension that is about 2 mm smaller than is possible when using conventional types of transmission.
- the distance between the center axis of the drive pin and the drive rod remote end face of the transmission is particularly advantageous in so-called English windows, which are opened to the outside. With such windows, because of the dimension of the window sash, there is particularly little space available.
- the first intermediate gear is rotatably mounted about a second axis of rotation perpendicular to the first axis of rotation. That the intermediate gear is arranged transversely to the example formed as a drive pinion input element.
- the first and the second rack section can thus be arranged laterally next to the intermediate gear, so that the relevant relative to the backset height of the transmission can be kept particularly low.
- the transmission element can be mounted linearly displaceable parallel to the first output element. This allows a particularly compact structure, since the two elements can be arranged, for example, directly next to one another, for example sliding past one another.
- the input member may be an input gear meshing with a transmission element rack portion provided on the slidable transmission member.
- a transmission element rack portion provided on the slidable transmission member.
- the transmission element itself is designed as a toothed rack.
- the input gear preferably has a toothing, which is limited to an angular range of a maximum of about 180 °. That the input gear is preferably not fully circular in longitudinal section, but e.g. semicircular or quarter circle. This allows a further reduction in the height and in particular the Schudorn beauts.
- the transmission is integrated in a particular firmly connected to a faceplate of the fitting housing.
- This housing can be made relatively small, so that it can be used both in receptacles for 20 mm fittings as well as in receptacles for 22 mm fittings and both inward-opening window and for English windows.
- An embodiment of the invention provides that the transmission element and the first output element are guided in respective sliding guides of the housing. This results in a particularly simple and space-saving design.
- the first and the second rack section are arranged on opposite sides of the intermediate gear with respect to the axis of rotation of the intermediate gear.
- the intermediate gear is then supported when switching of the fitting on one side of the housing-fixed first rack section and drives on the other side of the sliding second rack section.
- the axis of rotation of the intermediate gear moves in a straight line between the two rack sections along.
- the intermediate gear can be relatively small, so that a particularly compact construction is possible.
- the fitting may further comprise a second output member of the transmission which is coupled or coupleable to a second drive rod, the first and second output members being coupled together by a direction reversal device.
- a counter drive mechanism can be realized, as required in many fitting arrangements.
- a second intermediate gear can be provided for direction reversal, which meshes with the second rack portion or with an extending in an extension to this further rack portion of the first output member and with a counter-rack portion of the second output member.
- a direction reversal can be effected in a particularly simple and space-saving manner. Due to the coupling by two arranged transversely to the input pinion intermediate gears, the mutually displaceable output elements must not be arranged overlapping, but can move when moving in a common plane, for example, they strike each other in an end position. In contrast, a bend is required in conventional fittings, since both output elements or rods must be performed on a common pinion.
- the second or further rack section of the first output element and the counter rack section of the second output element are arranged at opposite sides of the second intermediate gear relative to a rotation axis of the second intermediate gear.
- the second idler gear is in this embodiment between the two rack sections and shifts them in opposite directions. The structure of such an arrangement is particularly compact.
- the second intermediate gear can be mounted immovably in or on a housing-fixed element of the transmission. This is particularly useful when the counter drive no further Huberhöhung is required, since the second or the further rack section of the first output element yes already moved to the opposite to the transmission element stroke. However, if a larger Huberhöhung desired, the second and / or further intermediate gears can be slidably mounted in an analogous manner to the first intermediate gear.
- the first and second idler gear have the same radius and the same number of teeth. This allows a particularly simple and compact design.
- the input element is coupled or can be coupled to an actuating element of the fitting.
- the actuating element may in particular be a handle. From the actuator, for example, in a known manner a square mandrel protrude, which engages positively in a correspondingly shaped square socket of the input element.
- the in Fig. 1-3 shown fitting comprises a gear 14 having an input element in the form of an input gear 16 and two counter-displaceable drive rails 18, 20 (FIG. Fig. 3 ), which form a first and a second output element of the transmission 14.
- the input gear 16 includes a toothing 17 and is rotatably mounted for switching the fitting about a first axis of rotation R1.
- the toothing 17 of the input gear 16 is limited to an angular range of slightly more than 180 ° about the first axis of rotation R1.
- the transmission 14 is integrated in a housing 22 with a base body 23 and a cover element, not shown. About attachment extensions 24, the housing 22 can be fastened to a cuff rail, not shown.
- the first drive rail 18 and the second drive rail 20 are displaceable in each case along their longitudinal axes in and counter to a displacement direction V, which runs at right angles to the first axis of rotation R1 arranged in the housing 22.
- sliding guide elements 26 are provided for this purpose, which are in engagement with sliding guides 27 of the housing 22 ( Fig. 2 ).
- square pins 28, 30 are formed in the illustrated embodiment, which are used for positive engagement in corresponding recesses of drive rods, not shown, of the fitting. With a correspondingly long training, as can be seen on the square pin 30, this can also be used as a locking pin.
- a central passage 31 of the input gear 16 has a rectangular cross section, which is adapted for the positive engagement of a square mandrel of an actuating element.
- the housing 22 can be inserted into a recess in a fold of a wing of a window, a door or the like.
- a rail-like transmission element 32 is drivingly arranged between the input gear 16 and the first drive rail 18.
- the transmission element 32 is slidably mounted in the housing 22 by means of sliding guide elements 33 parallel to the drive rails 18, 20.
- lower side 34 of the transmission element 32 is in the representations according to Fig. 1-3 non-visible transmission element rack section 35 (FIG. Fig. 4 ), which meshes with the input gear 16.
- the transmission element 32 can be driven by rotating the input gear 16 to a sliding movement in or against the displacement direction V.
- a first intermediate gear 38 is arranged, which is about a first axis of rotation R1 perpendicularly extending second axis of rotation R2 is rotatably mounted on the transmission element 32.
- the first intermediate gear 38 meshes with a non-displaceable first rack portion 40 of the housing 22.
- the first intermediate gear 38 meshes with a, in Fig. 1-3 also not visible, second rack section 51 (FIG. Fig. 6 ), which is integrally formed on the first drive rail 18.
- a second intermediate gear 44 which has the same radius and the same number of teeth as the first intermediate gear 38 and is preferably designed identically to this, is rotatable around a parallel to the second axis of rotation R2 extending third axis of rotation R3, but non-displaceably mounted in the housing 22.
- the second idler gear 44 meshes with another rack portion of the first drive rail 18 which, as in FIG Fig. 6 shown at 52 as an extension of the second rack portion 51 is formed.
- the second intermediate gear 44 meshes with a in Fig. 5 recognizable counter-rack portion 50 of the second drive rail 20th
- Fig. 4 the transmission element 32 is shown detached from the transmission 14. In this illustration, in particular, the transmission element rack section 35 can be seen.
- the first drive rail 18 is provided with a recess 45 to allow lateral sliding of the drive rails 18, 20 past each other.
- the drive rails 18, 20 can therefore be moved in a common plane. In the in Fig. 1-3 shown starting position, the drive rails 18, 20 abut each other.
- the positions of the second rack portion 51 and the other rack portion 52 are in Fig. 6 illustrated by corresponding arrows.

Due to the slidable mounting of the first idler gear 38, the stroke that the first drive rail 18 makes upon rotation of the input gear 16 by a certain rotation angle is twice as large as the corresponding stroke of the transmission element 32.
- the second drive rail 20 becomes the same double stroke , but shifted against the direction of displacement V, wherein the direction reversal is brought about by the second intermediate gear 44.
- the sliding movement of the drive rails 18, 20 implemented in a corresponding movement of the drive rods of the fitting.

Description
Die vorliegende Erfindung betrifft einen Beschlag für Fenster, Türen oder dergleichen, mit einem Getriebe, welches ein zum Schalten des Beschlags um eine erste Drehachse drehbar gelagertes Eingangselement und ein mit einer ersten Treibstange gekoppeltes oder koppelbares, verschiebbares erstes Ausgangselement aufweist.The present invention relates to a fitting for windows, doors or the like, with a transmission, which has a rotatably mounted for switching the fitting about a first axis of rotation input element and a coupled to a first drive rod or couplable, displaceable first output element.
Derartige Beschläge werden beispielsweise als sogenannte Kantenverschlüsse in Falznuten eines Flügels des Fensters, der Tür oder dergleichen eingesetzt. Zum Schalten des Beschlags, z.B. zwecks Verriegeln oder Entriegeln des Flügels gegenüber einem Rahmen, wird das Eingangselement mittels eines Betätigungselements wie einem Handgriff gedreht. Das Getriebe setzt diese Drehbewegung in eine Verschiebebewegung einer Treibstange um, welche ihrerseits die Ver- oder Entriegelung des Flügels bewirkt. Im einfachsten Fall erfolgt die Umsetzung von der Drehbewegung in eine Verschiebebewegung durch eine Anordnung aus Ritzel und Zahnstange. D.h. das Eingangselement kann als Ritzel ausgebildet sein, welches mit einer die Treibstange antreibenden Zahnstange kämmt.Such fittings are used for example as so-called edge seals in rabbet grooves of a wing of the window, the door or the like. For switching the fitting, e.g. in order to lock or unlock the sash against a frame, the input member is rotated by means of an actuator such as a handle. The transmission converts this rotational movement into a displacement movement of a drive rod, which in turn causes the locking or unlocking of the wing. In the simplest case, the implementation of the rotational movement takes place in a sliding movement by an arrangement of pinion and rack. That the input member may be formed as a pinion, which meshes with a rack driving the drive rod.
Getriebe der genannten Art müssen üblicherweise hinsichtlich der Verschiebebewegung der Treibstange einen bestimmten Mindesthub aufweisen, welcher bei Standardbeschlägen z.B. 18 mm beträgt. Da der maximale Drehwinkel des Ritzels aus Gründen der einfachen Bedienbarkeit des Beschlags beschränkt ist, z.B. auf 90°, kommen bei gängigen Beschlaggetrieben relativ große Ritzel zum Einsatz, welche einen beträchtlichen Bauraum beanspruchen. Bei vielen Anwendungen ist jedoch nur wenig Platz zum Anordnen des Beschlaggetriebes vorhanden. Dieses Problem wird dadurch noch verschärft, dass in einem Beschlaggetriebe häufig auch Bauraum für einen Gegenantrieb vorzusehen ist, welcher dem Antrieb einer weiteren Treibstange gegenläufig zu der ersten Treibstange dient.Transmission of the type mentioned must usually have a certain minimum stroke with respect to the displacement movement of the drive rod, which is for example 18 mm in standard fittings. Since the maximum angle of rotation of the pinion for reasons of ease of use of the fitting is limited, for example, to 90 °, come in popular fitting gear relatively large pinion used, which has a considerable amount of space claim. In many applications, however, there is little space for arranging the fitting gear. This problem is exacerbated by the fact that in a fitting gear often space for a counter drive is provided, which serves to drive a further drive rod opposite to the first drive rod.
Der Erfindung liegt die Aufgabe zugrunde, einen Beschlag der eingangs genannten Art zu schaffen, der weniger Bauraum beansprucht.The invention has for its object to provide a fitting of the type mentioned, which takes up less space.
Die Aufgabe wird durch einen Beschlag mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a fitting with the features of claim 1.
Erfindungsgemäß ist zum Umsetzen einer Drehbewegung des Eingangselements in eine Verschiebebewegung des ersten Ausgangselements ein verschiebbares Übertragungselement vorgesehen, welches durch Drehen des Eingangselements zu einer Verschiebebewegung antreibbar ist, wobei in oder an dem verschiebbaren Übertragungselement ein erstes Zwischenzahnrad drehbar gelagert ist, welches mit einem ersten, gehäusefesten Zahnstangenabschnitt und mit einem zweiten, an dem ersten Ausgangselement vorgesehenen Zahnstangenabschnitt kämmt. Die Umsetzung einer Drehbewegung des Eingangselements in eine Verschiebebewegung des Übertragungselements kann z.B. dadurch erfolgen, dass das Eingangselement als Zahnrad ausgebildet ist und mit einem Zahnstangenabschnitt des Übertragungselements kämmt.According to the invention, a displaceable transmission element is provided for converting a rotational movement of the input element into a displacement movement of the first output element, which is drivable by rotating the input element to a sliding movement, wherein in or on the displaceable transmission element, a first intermediate gear is rotatably mounted, which with a first, fixed to the housing Rack section and with a second, provided on the first output member rack section meshes. The conversion of a rotary movement of the input element into a displacement movement of the transmission element may be e.g. be effected in that the input element is designed as a gear and meshes with a rack portion of the transmission element.
Bei einer Drehbewegung des Eingangselements und einer dadurch bewirkten Verschiebebewegung des Übertragungselements rollt das in oder an dem Übertragungselement gelagerte Zwischenzahnrad an dem gehäusefesten Zahnstangenabschnitt ab und treibt dabei über den zweiten Zahnstangenabschnitt das erste Ausgangselement zu einer Verschiebebewegung an. Der Hub des ersten Ausgangselements relativ zu einem gehäusefesten Bezugspunkt setzt sich dabei zusammen aus der Verschiebung der Drehachse des Zwischenzahnrads einerseits und aus dem durch die Abrollbewegung des Zwischenzahnrads bewirkten Vortrieb des zweiten Zahnstangenabschnitts relativ zur Drehachse des Zwischenzahnrads andererseits.During a rotational movement of the input element and a displacement movement of the transmission element caused thereby, the intermediate gear mounted in or on the transmission element rolls off the toothed rack section fixed to the housing and drives the first output element into a sliding movement via the second rack section at. The stroke of the first output element relative to a housing-fixed reference point is composed here of the displacement of the axis of rotation of the intermediate gear on the one hand and from the caused by the rolling movement of the intermediate gear propulsion of the second rack portion relative to the axis of rotation of the idler gear on the other.
Durch das verschiebbar gelagerte Zwischenzahnrad wird also in ähnlicher Weise wie bei einem Planetengetriebe der Hub des Übertragungselements in einen vergrößerten Hub des ersten Ausgangselements übersetzt. Insbesondere kann dadurch der Hub des ersten Ausgangselements gegenüber dem Hub des Übertragungselements verdoppelt werden. Dadurch ist es möglich, für einen vorgegebenen Hub der Treibstange und einen vorgegebenen maximalen Drehwinkel des Eingangselements ein vergleichsweise kleines Ritzel als Eingangselement zu verwenden, so dass ein erfindungsgemäßes Beschlaggetriebe besonders platzsparend gestaltet werden kann.As a result of the displaceably mounted idler gear, the stroke of the transmission element is thus translated into an enlarged stroke of the first output element in a manner similar to that of a planetary gear. In particular, the stroke of the first output element relative to the stroke of the transmission element can thereby be doubled. This makes it possible to use a comparatively small pinion as an input element for a given stroke of the drive rod and a predetermined maximum rotation angle of the input element, so that a fitting mechanism according to the invention can be designed to save space.
Insbesondere hat sich herausgestellt, dass durch eine erfindungsgemäße Gestaltung ein Beschlag mit einem um etwa 2 mm geringeren Hinterdornmaß bereitgestellt werden kann als dies bei Verwendung herkömmlicher Getriebearten möglich ist. Unter dem Hinterdornmaß wird auf dem Fachgebiet der Abstand zwischen der Mittelachse des Antriebsdorns und der treibstangenfernen Abschlussfläche des Getriebes verstanden. Die durch die Erfindung ermöglichte Verringerung des Hinterdornmaßes eines Beschlags ist insbesondere bei so genannten englischen Fenstern vorteilhaft, welche nach außen geöffnet werden. Bei solchen Fenstern steht nämlich aufgrund der Dimension des Fensterflügels besonders wenig Bauraum zur Verfügung.In particular, it has been found that by a design according to the invention a fitting can be provided with a rear mandrel dimension that is about 2 mm smaller than is possible when using conventional types of transmission. Under the Hinterdornmaß is understood in the art, the distance between the center axis of the drive pin and the drive rod remote end face of the transmission. The reduction in Hinterdornmaßes of a fitting made possible by the invention is particularly advantageous in so-called English windows, which are opened to the outside. With such windows, because of the dimension of the window sash, there is particularly little space available.
Die meisten standardmäßig verwendeten Beschläge in England weisen ein Dornmaß von 20 mm oder von 22 mm auf. Unter dem Dornmaß wird auf dem Fachgebiet der Abstand zwischen der Mittelachse des Antriebsdorns und der Vorderfläche der Stulpschiene verstanden. Die Bauhöhe des Getriebes setzt sich also aus dem Dornmaß und dem Hinterdornmaß zusammen. Da zur Aufnahme des Getriebegehäuses üblicherweise eine Metallarmierung im Falz des Flügels vorgesehen ist, können Beschläge mit einem Dornmaß von 22 mm im Allgemeinen nicht in Flügeln eingesetzt werden, welche für Beschläge mit einem Dornmaß von 20 mm ausgebildet sind. Durch die Verringerung der Bauhöhe des Getriebegehäuses ermöglicht die Erfindung jedoch die Verwendung eines einzigen Getriebetyps für beide Arten von Flügeln.Most standard fittings used in England have a backset of 20mm or 22mm. By the backset is understood in the art the distance between the center axis of the drive pin and the front surface of the faceplate. The overall height of the transmission is thus composed of the backset and the rear spine. Since a metal reinforcement in the rebate of the wing is usually provided for receiving the gear housing, fittings with a backset of 22 mm generally can not be used in wings, which are designed for fittings with a backset of 20 mm. However, by reducing the overall height of the transmission housing, the invention enables the use of a single type of transmission for both types of vanes.
Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen, der Beschreibung sowie den beigefügten Zeichnungen angegeben.Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.
Bevorzugt ist das erste Zwischenzahnrad um eine rechtwinklig zu der ersten Drehachse verlaufende zweite Drehachse drehbar gelagert. D.h. das Zwischenzahnrad ist quer zu dem beispielsweise als Antriebsritzel ausgebildeten Eingangselement angeordnet. Der erste und der zweite Zahnstangenabschnitt können somit seitlich neben dem Zwischenzahnrad angeordnet werden, so dass die hinsichtlich des Dornmaßes relevante Bauhöhe des Getriebes besonders gering gehalten werden kann.Preferably, the first intermediate gear is rotatably mounted about a second axis of rotation perpendicular to the first axis of rotation. That the intermediate gear is arranged transversely to the example formed as a drive pinion input element. The first and the second rack section can thus be arranged laterally next to the intermediate gear, so that the relevant relative to the backset height of the transmission can be kept particularly low.
Weiterhin kann das Übertragungselement parallel zu dem ersten Ausgangselement linear verschiebbar gelagert sein. Dies ermöglicht einen besonders kompakten Aufbau, da die beiden Elemente z.B. unmittelbar nebeneinander angeordnet werden können, z.B. aneinander vorbei gleitend.Furthermore, the transmission element can be mounted linearly displaceable parallel to the first output element. This allows a particularly compact structure, since the two elements can be arranged, for example, directly next to one another, for example sliding past one another.
Wie vorstehend erwähnt kann das Eingangselement ein Eingangszahnrad sein, welches mit einem an dem verschiebbaren Übertragungselement vorgesehenen Übertragungselement-Zahnstangenabschnitt kämmt. Dies ermöglicht eine besonders einfache und kompakte Umsetzung einer Drehbewegung des Eingangselements in eine lineare Verschiebebewegung des ersten Ausgangselements. Gemäß einer besonders einfachen Ausgestaltung ist das Übertragungselement selbst als Zahnstange ausgebildet.As mentioned above, the input member may be an input gear meshing with a transmission element rack portion provided on the slidable transmission member. This allows a particularly simple and compact implementation of a rotational movement of the input element in a linear displacement movement of the first output element. According to a particularly simple embodiment, the transmission element itself is designed as a toothed rack.
Das Eingangszahnrad weist bevorzugt eine Verzahnung auf, die auf einen Winkelbereich von maximal ca. 180° beschränkt ist. D.h. das Eingangszahnrad ist vorzugsweise im Längsschnitt nicht vollkreisförmig, sondern z.B. halbkreis- oder viertelkreisförmig. Dies ermöglicht eine weitere Verringerung der Bauhöhe und insbesondere des Hinterdornmaßes.The input gear preferably has a toothing, which is limited to an angular range of a maximum of about 180 °. That the input gear is preferably not fully circular in longitudinal section, but e.g. semicircular or quarter circle. This allows a further reduction in the height and in particular the Hinterdornmaßes.
Gemäß einer Ausgestaltung der Erfindung ist das Getriebe in ein insbesondere fest mit einer Stulpschiene des Beschlags verbundenes Gehäuse integriert. Dieses Gehäuse kann vergleichsweise klein gestaltet werden, so dass es sowohl in Aufnahmen für 20 mm-Beschläge als auch in Aufnahmen für 22 mm-Beschläge sowie sowohl für nach innen öffnende Fenster als auch für englische Fenster eingesetzt werden kann.According to one embodiment of the invention, the transmission is integrated in a particular firmly connected to a faceplate of the fitting housing. This housing can be made relatively small, so that it can be used both in receptacles for 20 mm fittings as well as in receptacles for 22 mm fittings and both inward-opening window and for English windows.
Eine Ausführungsform der Erfindung sieht vor, dass das Übertragungselement und das erste Ausgangselement in jeweiligen Gleitführungen des Gehäuses geführt sind. Hierdurch ergibt sich ein besonders einfacher und platzsparender Aufbau.An embodiment of the invention provides that the transmission element and the first output element are guided in respective sliding guides of the housing. This results in a particularly simple and space-saving design.
Gemäß einer weiteren Ausführungsform der Erfindung sind der erste und der zweite Zahnstangenabschnitt an bezüglich der Drehachse des Zwischenzahnrads gegenüberliegenden Seiten des Zwischenzahnrads angeordnet. Das Zwischenzahnrad stützt sich dann also bei einem Schalten des Beschlags auf einer Seite an dem gehäusefesten ersten Zahnstangenabschnitt ab und treibt auf der anderen Seite den verschiebbaren zweiten Zahnstangenabschnitt an. Die Rotationsachse des Zwischenzahnrads wandert dabei geradlinig zwischen den beiden Zahnstangenabschnitten entlang. Das Zwischenzahnrad kann hierbei relativ klein sein, so dass eine besonders kompakte Konstruktion möglich ist.According to a further embodiment of the invention, the first and the second rack section are arranged on opposite sides of the intermediate gear with respect to the axis of rotation of the intermediate gear. The intermediate gear is then supported when switching of the fitting on one side of the housing-fixed first rack section and drives on the other side of the sliding second rack section. The axis of rotation of the intermediate gear moves in a straight line between the two rack sections along. The intermediate gear can be relatively small, so that a particularly compact construction is possible.
Der Beschlag kann ferner ein zweites Ausgangselement des Getriebes umfassen, welches mit einer zweiten Treibstange gekoppelt oder koppelbar ist, wobei das erste und das zweite Ausgangselement über eine Einrichtung zur Richtungsumkehr miteinander gekoppelt sind. Somit kann ein Gegenantriebsmechanismus realisiert werden, wie er bei vielen Beschlaganordnungen gefordert ist.The fitting may further comprise a second output member of the transmission which is coupled or coupleable to a second drive rod, the first and second output members being coupled together by a direction reversal device. Thus, a counter drive mechanism can be realized, as required in many fitting arrangements.
Insbesondere kann zur Richtungsumkehr ein zweites Zwischenzahnrad vorgesehen sein, welches mit dem zweiten Zahnstangenabschnitt oder mit einem sich in einer Verlängerung zu diesem erstreckenden weiteren Zahnstangenabschnitt des ersten Ausgangselements und mit einem Gegen-Zahnstangenabschnitt des zweiten Ausgangselements kämmt. Durch ein solches Zwischenzahnrad kann auf besonders einfache und platzsparende Weise eine Richtungsumkehr bewirkt werden. Aufgrund der Kopplung durch zwei quer zu dem Eingangsritzel angeordnete Zwischenzahnräder müssen die gegeneinander verschiebbaren Ausgangselemente nicht überlappend angeordnet sein, sondern können sich beim Verschieben in einer gemeinsamen Ebene bewegen, wobei sie z.B. in einer Endstellung aneinander anschlagen. Demgegenüber ist bei herkömmlichen Beschlägen eine Abkröpfung erforderlich, da beide Ausgangselemente bzw. Treibstangen über ein gemeinsames Ritzel geführt werden müssen.In particular, a second intermediate gear can be provided for direction reversal, which meshes with the second rack portion or with an extending in an extension to this further rack portion of the first output member and with a counter-rack portion of the second output member. By means of such an intermediate gear, a direction reversal can be effected in a particularly simple and space-saving manner. Due to the coupling by two arranged transversely to the input pinion intermediate gears, the mutually displaceable output elements must not be arranged overlapping, but can move when moving in a common plane, for example, they strike each other in an end position. In contrast, a bend is required in conventional fittings, since both output elements or rods must be performed on a common pinion.
Es kann vorgesehen sein, dass der zweite oder der weitere Zahnstangenabschnitt des ersten Ausgangselements und der Gegen- Zahnstangenabschnitt des zweiten Ausgangselements an bezüglich einer Drehachse des zweiten Zwischenzahnrads gegenüberliegenden Seiten des zweiten Zwischenzahnrads angeordnet sind. Das zweite Zwischenzahnrad befindet sich bei dieser Ausgestaltung zwischen den beiden Zahnstangenabschnitten und verschiebt diese in gegenläufiger Weise. Der Aufbau einer solchen Anordnung ist besonders kompakt.It can be provided that the second or further rack section of the first output element and the counter rack section of the second output element are arranged at opposite sides of the second intermediate gear relative to a rotation axis of the second intermediate gear. The second idler gear is in this embodiment between the two rack sections and shifts them in opposite directions. The structure of such an arrangement is particularly compact.
Das zweite Zwischenzahnrad kann unverschiebbar in oder an einem gehäusefesten Element des Getriebes gelagert sein. Dies ist insbesondere dann sinnvoll, wenn am Gegenantrieb keine weitere Huberhöhung erforderlich ist, da sich der zweite oder der weitere Zahnstangenabschnitt des ersten Ausgangselements ja bereits um den gegenüber dem Übertragungselement vergrößerten Hub bewegt. Ist hingegen eine größere Huberhöhung gewünscht, so können das zweite und/oder weitere Zwischenzahnräder in analoger Weise zu dem ersten Zwischenzahnrad verschiebbar gelagert sein.The second intermediate gear can be mounted immovably in or on a housing-fixed element of the transmission. This is particularly useful when the counter drive no further Huberhöhung is required, since the second or the further rack section of the first output element yes already moved to the opposite to the transmission element stroke. However, if a larger Huberhöhung desired, the second and / or further intermediate gears can be slidably mounted in an analogous manner to the first intermediate gear.
Vorzugsweise weisen das erste und das zweite Zwischenzahnrad den gleichen Radius und die gleiche Zähnezahl auf. Dies ermöglicht eine besonders einfache und kompakte Konstruktion.Preferably, the first and second idler gear have the same radius and the same number of teeth. This allows a particularly simple and compact design.
Gemäß einer weiteren Ausgestaltung der Erfindung ist das Eingangselement mit einem Betätigungselement des Beschlags gekoppelt oder koppelbar. Bei dem Betätigungselement kann es sich insbesondere um einen Handgriff handeln. Von dem Betätigungselement kann z.B. in bekannter Weise ein Vierkantdorn abstehen, welcher formschlüssig in eine entsprechend gestaltete Vierkantaufnahme des Eingangselements eingreift.According to a further embodiment of the invention, the input element is coupled or can be coupled to an actuating element of the fitting. The actuating element may in particular be a handle. From the actuator, for example, in a known manner a square mandrel protrude, which engages positively in a correspondingly shaped square socket of the input element.
