Definitions

  • the invention relates to a turning handle according to the preamble of claim 1.
  • a locking bolt that engages in a striking plate or in a striker on the window frame is used in particular for swing and swing-sash windows.
  • the handles are arranged somewhat obliquely to the elongated screw-on box in order to achieve better access to the window frame.
  • lockable or lockable window handles for securing closed windows, especially against unauthorized opening. They have a handle which is rotatably mounted in a stop body and is non-rotatably connected to an actuating square or a swiveling locking bolt. In the closed position prevents a spring-loaded locking element or a locking device, for. B. a lock cylinder, turning the window handle into the open position. The window can only be opened after the locking element or the locking cylinder has been actuated.
  • a window handle provided with a step-shaped neck recess with a neck extension penetrates a stop plate which has at least one bore on its upper side.
  • a sleeve is fixed in the neck recess, in which a locking bolt is axially displaceably mounted. It has a pull button at its upper end and is loaded downwards by a compression spring which is supported on the sleeve, so that in the locked position the lower end of the bolt is extended by the force of the spring and engages in one of the holes in the stop plate. It is then not possible to turn the window handle.
  • To unlock the bolt is lifted by pulling the pull button axially and, if necessary, locked in an upper locking position. Even when the bolt is in the locked position, the pull button must protrude sufficiently from the top of the handle to ensure access at all. This may affect handling, especially if the button is very small.
  • EP-A-0 241 245 describes a rotary handle with a shaft body rotatably mounted on a mounting plate, on which an offset operating handle engages.
  • a spring-loaded piston is guided axially displaceably in a recess in the shaft. Its upper end protrudes from the surface of the shaft as a push button, while the lower end has a nose which sits over a hole in a base plate provided under the shaft. In the open position, the compression spring is relaxed and the nose end of the bolt is flush with the base plate. This has a bore from which, in the open position, a beveled bolt or bolt protrudes against the pressure of a spring.
  • the shaft slides over the bolt and pushes it back into its bore until the bore of the base plate comes to rest over the bolt in the end position of the shaft. He pushes the nose of the piston back under the force of his spring and engages in the bore so that the handle is locked.
  • the piston is pressed down at its upper end, which causes the latch to be lifted out of the base plate hole and the handle to be pivoted.
  • the construction is relatively complex because two spring-loaded locking elements are necessary.
  • a handle according to the preamble of claim 1 emerges from NL-A-8 800 104.
  • the window and door closer described therein has a handle that is angled in its axis of rotation and rotatably mounted in a rosette, which is connected in a rotationally fixed manner to a locking bolt that can be swung out to the side of the rosette.
  • a sleeve in which a spring-loaded bolt is axially supported with a push button, the lower end of the bolt reaching through the rosette and carrying an essentially rectangular locking plate on its inside. Both in the open and in the closed position, the locking plate rests on the inner surface of the rosette and, due to its dimensions, prevents the locking bolt from pivoting.
  • the aim of the invention is to develop a turning handle which ensures safe and reliable locking with little effort.
  • the aim is also to be able to adjust the locking elements in an aesthetically pleasing manner without impairing the operational reliability of the outer shape of the rotary handle. If required, different securing devices should be able to be used without fundamental changes to the basic construction.
  • the invention provides according to the characterizing part of claim 1 that in the rosette itself the screw-on surface supporting support body, which in turn has a contact surface for the bolt and a hole for the guide bush.
  • This structure is as simple as it is robust. It is important that the support body supports the rosette stably so that the deformations that are possible with conventional fittings cannot occur.
  • the components can be designed to be space-saving and ensure easy assembly and permanent, reliable usability.
  • the carrier body is designed as a substantially rectangular, folded on the narrow sides steel plate, which has a stop angle for a latch side surface on one long side. This stop angle also causes a substantial stiffening of the structure and relieves the rosette cap, which had to take over the corresponding stop function on a longitudinal wall in conventional constructions.
  • connection of the handle neck and latch is carried out according to claim 3 with the interposition of the carrier body by crimping or screwing in the axial direction and by a form-fit entrainment in the direction of rotation. It can be seen that this ensures simple assembly and, thanks to its high strength, permanent serviceability.
  • the invention according to claim 4 alternatively provides that the bolt is rigidly connected or integrally with a particularly weakly conically shaped profile part, which is form-fitting in an opposite profile recess of the Handle neck engages.
  • This version is particularly suitable for a screw connection that reliably absorbs large tensile and compressive forces or moments.
  • the rosette and / or the support body in particular, has screw holes arranged on the narrow side, so that both components can be fastened together on the screw-on surface.
  • the carrier body for Receiving the locking pin end next to the guide bore has an opening with an area that is at least approximately flush with the side surface of the bolt when it is pivoted into its closed position.
  • the locking bolt end thus also penetrates the carrier body at a point selected in such a way that in its closed position the bolt rests with a side face on the locking bolt, so that the handle cannot be actuated without prior unlocking.
  • So-called child safety devices have a locking bolt which is loaded by a spring towards the closed position.
  • the invention provides according to claim 7 that the locking pin is guided in the grip head in a socket body on which an articulated and / or flexible actuating member is supported with the upper locking pin part.
  • the articulated or flexible connection allows the direction of movement of the locking bolt to deviate from that of the actuating member, whereby a considerable gain in space can be achieved.
  • the actuating member is designed as a slide which can be adjusted parallel to the outer surface of the handle and has a flexible connecting part which acts on the upper part of the locking bolt in a directionally variable manner.
  • the embodiment of claim 9 is very advantageous, according to which the connecting part is a plastic band with a thickened end, which is in one piece with the slider and is largely enclosed in particular by an outwardly narrowed transverse opening on the upper part of the locking bolt.
  • the band is primarily subjected to tension and performs the deflection of the actuation direction out of the locking pin axis with very little effort.
  • the positive connection is very simple and largely free of wear.
  • the actuating member has a cover surface which at least slightly projects beyond the outer surface of the handle, which makes it easier to touch.
  • the top surface can be at least partially roughened, in particular corrugated with an arrow structure, and in particular can be concave to the outside. This ensures safe actuation by the thumb of the gripping hand.
  • the socket body has an outer flat part guiding the actuating member, which is fitted into an opposite recess in the grip head and is preferably fixed integrally therein.
  • the flat part protrudes towards a sleeve of the socket body in the direction of the main part of the handle and therefore offers the slide the necessary possibility of movement.
  • the fit in the handle head is preferably secured by gluing.
  • the spring loading the locking bolt can enclose it according to claim 13 in the recess and is supported on the lower end of the socket body, that is, on the sleeve part mentioned. This measure also contributes to a low overall height.
  • FIG. 14 Another design with a locking bolt, which is part of a locking cylinder attached in the neck-parallel recess of the handle head, is characterized according to claim 14 in that the bolt is supported by an additional inner plate against the screwing surface.
  • the inner plate can have tabs which extend into recesses in the carrier body and screw holes which are aligned with those of the carrier body.
  • the plate made of steel according to claim 16 has a central offset facing the bolt with a bore in which an intermediate ring bearing on the bolt is seated. Both the extent of the offset and the dimensioning of the intermediate ring allow a good adaptation to the local mounting conditions in such a way that the bolt and the handle firmly attached to it receive reliable support against the screwing surface.
  • claims 17 to 19 ensure proper guidance and thus rotatability of the bolt, which can be attached axially to the handle head by means of a heavy-duty screw fastening, and thus the handle holds securely. It helps if the fastening screw can be anchored in a preferably slightly conical blind hole according to claim 20.
  • the handle generally illustrated in FIG. 1 consists of a handle 10, the handle head 12 of which continues with a handle neck 14, a shoulder 16 and a square 18.

  • the latter has a square hole 28 for receiving the square 18 when assembling the fitting, its axially fixed / rotatable connection being secured by a flange 39 (FIGS. 2a, 3a).
  • FIGS. 2a to 2c and FIGS. 3 to 3c The structure and function of the assembled unit can be seen from FIGS. 2a to 2c and FIGS. 3 to 3c.
  • the handle 10 In the locked position, the handle 10 is at an angle to the rosette 20 so that the extension 15 of the handle and an arm or arch part 27 of the bolt project beyond the rosette 20 on one long side (FIGS. 2b, 2c). Unlocking takes place by pivoting the handle 10 upward (FIGS. 3b, 3c). It can be seen that the handle 10 can have a thumb rest 11 in the area of the handle head 12 for easy handling. It is important that the steel lower plate 30 together with the rosette 20 support the entire fitting on a (not shown) screwing surface, the screw holes 21, 31 being arranged near the ends of the box-shaped structure. Instead of a pair of holes as shown, two pairs of holes can also be provided near the corners in order to ensure even greater strength of the screw connection.

Description

Die Erfindung bezieht sich auf eine Drehhandhabe gemäß dem Oberbegriff von Anspruch 1.The invention relates to a turning handle according to the preamble of claim 1.

Namentlich für Drehflügel- und Schwingflügelfenster benutzt man einen Verschlußriegel, der in ein Schließblech bzw. in ein Schließteil am Fensterrahmen eingreift. Oberhalb des Riegels befindet sich am Griff ein seitlicher Ansatz, der als Nase am Schließteil eine wenig geöffnete Stellung erlaubt, die eine begrenzte Lüftung ermöglicht. Im allgemeinen sind die Griffe etwas schräg zu dem länglichen Anschraubkasten angeordnet, um eine bessere Zugänglichkeit am Fensterrahmen zu erzielen.A locking bolt that engages in a striking plate or in a striker on the window frame is used in particular for swing and swing-sash windows. Above the bolt there is a side extension on the handle, which allows a little open position as a nose on the locking part, which allows limited ventilation. In general, the handles are arranged somewhat obliquely to the elongated screw-on box in order to achieve better access to the window frame.

Je nach Öffnungsrichtung benötigt man linke und rechte Griff-Ausführungen. Ferner gibt es zur Sicherung von geschlossenen Fenstern, vor allem gegen unbefugtes Öffnen, abschließ- oder verriegelbare Fenstergriffe. Sie haben einen drehbar in einem Anschlagkörper gelagerten Griff, der drehfest mit einem Betätigungs-Vierkant oder einem schwenkbaren Schließriegel verbunden ist. In Schließstellung verhindert ein federnd gelagertes Rastelement oder eine Schließvorrichtung, z. B. ein Schließzylinder, das Verdrehen des Fenstergriffes in die Öffnungsstellung. Erst nach Betätigung des Rastelements bzw. des Schließzylinders ist ein Öffnen des Fensters möglich.Depending on the opening direction, left and right handle versions are required. There are also lockable or lockable window handles for securing closed windows, especially against unauthorized opening. They have a handle which is rotatably mounted in a stop body and is non-rotatably connected to an actuating square or a swiveling locking bolt. In the closed position prevents a spring-loaded locking element or a locking device, for. B. a lock cylinder, turning the window handle into the open position. The window can only be opened after the locking element or the locking cylinder has been actuated.

Ein Beispiel einer solchen Drehhandhabe ist aus DE-U-8 432 060 bekannt. Danach durchsetzt ein mit einer stufenförmigen Hals-Ausnehmung versehener Fenstergriff mit einem Halsansatz eine Anschlagplatte, die an ihrer Oberseite wenigstens eine Bohrung aufweist. In der Hals-Ausnehmung ist eine Hülse festgelegt, in der ein Schließbolzen axialverschieblich gelagert ist. Er besitzt an seinem oberen Ende einen Ziehknopf und wird von einer Druckfeder nach unten belastet, die sich an der Hülse abstützt, so daß in verriegelter Stellung das untere Bolzen-Ende durch die Kraft der Feder ausgefahren ist und in eine der Bohrungen der Anschlagplatte eingreift. Ein Verdrehen des Fenstergriffs ist dann nicht möglich. Zum Entriegeln wird der Bolzen durch axiales Ziehen am Ziehknopf angehoben und gegebenenfalls in einer oberen Raststellung arretiert. Selbst in der Riegelstellung des Bolzens muß der Ziehknopf von der Oberseite des Griffs in ausreichendem Maße abstehen, um überhaupt einen Zugriff zu gewährleisten. Dies kann unter Umständen die Handhabung beeinträchtigen, insbesondere dann, wenn der Knopf sehr klein ausgebildet ist.An example of such a turning handle is known from DE-U-8 432 060. Then a window handle provided with a step-shaped neck recess with a neck extension penetrates a stop plate which has at least one bore on its upper side. A sleeve is fixed in the neck recess, in which a locking bolt is axially displaceably mounted. It has a pull button at its upper end and is loaded downwards by a compression spring which is supported on the sleeve, so that in the locked position the lower end of the bolt is extended by the force of the spring and engages in one of the holes in the stop plate. It is then not possible to turn the window handle. To unlock, the bolt is lifted by pulling the pull button axially and, if necessary, locked in an upper locking position. Even when the bolt is in the locked position, the pull button must protrude sufficiently from the top of the handle to ensure access at all. This may affect handling, especially if the button is very small.

Die EP-A-0 241 245 beschreibt eine Drehhandhabe mit einem drehbar an einer Montageplatte gelagerten Schaftkörper, an dem ein versetzt angeordneter Betätigungsgriff angreift. In dem Schaft ist in einer Ausnehmung ein federbelasteter Kolben axialverschieblich geführt. Dessen oberes Ende ragt als Druckknopf aus der Oberfläche des Schaftes hervor, während das untere Ende eine Nase hat, die über einer Bohrung in einer unter dem Schaft angebrachten Bodenplatte sitzt. In geöffneter Stellung ist die Druckfeder entspannt und das Nasen-Ende des Bolzens schließt bündig mit der Bodenplatte ab. Diese hat eine Bohrung, aus der in geöffneter Stellung ein abgeschrägter Riegel oder Bolzen entgegen dem Druck einer Feder vorsteht. Dreht man den Betätigungsgriff in Schließrichtung, so gleitet der Schaft über den Riegel und drückt ihn in seine Bohrung zurück, bis in der Endstellung des Schafts die Bohrung der Bodenplatte über dem Riegel zu liegen kommt. Er schiebt unter der Kraft seiner Feder die Nase des Kolbens zurück und greift in die Bohrung ein, so daß die Handhabe verriegelt ist. Zum Öffnen wird der Kolben an seinem oberen Ende niedergedrückt, wodurch der Riegel aus der Bodenplatten-Bohrung ausgehoben wird und der Griff verschwenkt werden kann. Auch hier besteht das Problem, daß der Kolben von der Schaftoberseite absteht. Zudem ist die Konstruktion relativ aufwendig, da zwei federbelastete Riegelelemente notwendig sind.EP-A-0 241 245 describes a rotary handle with a shaft body rotatably mounted on a mounting plate, on which an offset operating handle engages. A spring-loaded piston is guided axially displaceably in a recess in the shaft. Its upper end protrudes from the surface of the shaft as a push button, while the lower end has a nose which sits over a hole in a base plate provided under the shaft. In the open position, the compression spring is relaxed and the nose end of the bolt is flush with the base plate. This has a bore from which, in the open position, a beveled bolt or bolt protrudes against the pressure of a spring. If you turn the actuating handle in the closing direction, the shaft slides over the bolt and pushes it back into its bore until the bore of the base plate comes to rest over the bolt in the end position of the shaft. He pushes the nose of the piston back under the force of his spring and engages in the bore so that the handle is locked. To open it, the piston is pressed down at its upper end, which causes the latch to be lifted out of the base plate hole and the handle to be pivoted. Here too there is the problem that the piston protrudes from the upper side of the shaft. In addition, the construction is relatively complex because two spring-loaded locking elements are necessary.

Eine Handhabe gemäß dem Oberbegriff des Anspruchs 1 geht aus NL-A-8 800 104 hervor. Der darin beschriebene Fenster- und Türschließer hat einen in seiner Drehachse eben abgewinkelten, in einer Rosette drehbar gelagerten Handgriff, der drehfest mit einem seitlich der Rosette ausschwenkbaren Schließriegel verbunden ist. Neben dem Handgriff ist eine Hülse, in der ein federbelasteter Bolzen mit einem Druckknopf axial gelagert ist, wobei das untere Ende des Bolzens durch die Rosette hindurchgreift und auf ihrer Innenseite eine im wesentlichen rechteckige Riegelplatte trägt. Sowohl im geöffneter als auch in geschlossener Stellung liegt die Riegelplatte an der Innenfläche der Rosette an und verhindert aufgrund ihrer Abmessungen ein Verschwenken des Schließriegels. Erst wenn der Bolzen entgegen der Federbelastung über den Druckknopf niedergedrückt wird, gibt die Riegelplatte den Schwenkriegel frei, so daß der Handgriff verschwenkt werden kann. Diese Anordnung ist aufgrund des freistehenden Bolzens nicht immer verwendbar und im praktischen Gebrauch ungünstig. Insbesondere wird sie hohen ästhetischen Ansprüchen an die Gestaltung von Fenster- und Türbeschlägen nicht gerecht, die zumeist ein einheitliches geschlossenes Design erfordern. Eine ähnliche gattungsgemäße Handhabe mit einer eine Führungsbuchse für den Griffhals aufnehmenden Rosette geht aus GB-A-1653806 hervor.A handle according to the preamble of claim 1 emerges from NL-A-8 800 104. The window and door closer described therein has a handle that is angled in its axis of rotation and rotatably mounted in a rosette, which is connected in a rotationally fixed manner to a locking bolt that can be swung out to the side of the rosette. In addition to the handle is a sleeve in which a spring-loaded bolt is axially supported with a push button, the lower end of the bolt reaching through the rosette and carrying an essentially rectangular locking plate on its inside. Both in the open and in the closed position, the locking plate rests on the inner surface of the rosette and, due to its dimensions, prevents the locking bolt from pivoting. Only when the bolt is pressed against the spring load by the push button, the locking plate releases the swivel bolt so that the handle can be pivoted. This arrangement is not always usable due to the free-standing bolt and is unfavorable in practical use. In particular, it does not meet the high aesthetic requirements for the design of window and door fittings, which usually require a uniform, closed design. A similar generic handle with a rosette receiving a guide bush for the handle neck emerges from GB-A-1653806.

Daher besteht Bedarf an Verbesserungen. Es ist das Ziel der Erfindung, eine Drehhandhabe zu entwickeln, die mit geringem Aufwand eine sichere und zuverlässige Verriegelbarkeit gewährleistet. Angestrebt wird ferner, die Verriegelungselemente in ästhetisch ansprechender Weise ohne Beeinträchtigung der Betriebszuverlässigkeit der äußeren Form der Drehhandhabe anpassen zu können. Nach Bedarf sollen unterschiedliche Sicherungsmittel ohne grundsätzliche Änderungen der Basis-Konstruktion einsetzbar sein.There is therefore a need for improvement. The aim of the invention is to develop a turning handle which ensures safe and reliable locking with little effort. The aim is also to be able to adjust the locking elements in an aesthetically pleasing manner without impairing the operational reliability of the outer shape of the rotary handle. If required, different securing devices should be able to be used without fundamental changes to the basic construction.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 20.This object is solved by the features of claim 1. Refinements are the subject of claims 2 to 20.

Bei einer Drehhandhabe, insbesondere Tür- oder Fenstergriff mit einem Griffkopf, dessen Hals an einer etwa kästchen- oder kappenförmigen Rosette axialfest und drehbar gelagert ist, die an einer Anschraubfläche z.B. eines Fensterrahmens befestigbar ist und mittig eine Führungsbuchse für den Griffhals bildet oder aufnimmt, welcher im Inneren der Rosette mit einem Riegel drehfest verbunden ist, der einen seitlich ausschwenkbaren Arm hat wobei der Riegel in verriegelter Stellung der Handhabe seitlich über den Rosettenkörper vorsteht, sieht die Erfindung gemäß dem kennzeichnenden Teil von Anspruch 1 vor, daß in der Rosette ein sich an der Anschraubfläche abstützender Trägerkörper anliegt, der seinerseits eine Anlagefläche für den Riegel sowie eine Bohrung für die Führungsbuchse aufweist. Dieser Aufbau ist ebenso einfach wie robust. Wichtig ist, daß der Trägerkörper die Rosette stabil unterstützt, so daß die bei herkömmlichen Beschlägen möglichen Verformungen nicht auftreten können. Die Bauteile können raumsparend gestaltet werden und gewährleisten leichte Montage sowie dauerhaft zuverlässige Benutzbarkeit.In the case of a turning handle, in particular a door or window handle with a handle head, the neck of which is axially fixed and rotatable on an approximately box-shaped or cap-shaped rosette, which can be fastened to a screw-on surface, for example a window frame, and which forms or receives a guide bushing for the handle neck in the middle, which is rotatably connected inside the rosette with a bolt which has a laterally pivotable arm, the bolt protruding laterally over the rosette body in the locked position of the handle, the invention provides according to the characterizing part of claim 1 that in the rosette itself the screw-on surface supporting support body, which in turn has a contact surface for the bolt and a hole for the guide bush. This structure is as simple as it is robust. It is important that the support body supports the rosette stably so that the deformations that are possible with conventional fittings cannot occur. The components can be designed to be space-saving and ensure easy assembly and permanent, reliable usability.

Nach Anspruch 2 ist der Trägerkörper als im wesentlichen rechteckige, an den Schmalseiten abgekantete Stahlplatte ausgebildet, die an einer Längsseite einen Anschlagwinkel für eine Riegel-Seitenfläche hat. Dieser Anschlagwinkel bewirkt zugleich eine wesentliche Versteifung des Aufbaues und entlastet die Rosettenkappe, welche bei herkömmlichen Konstruktionen die entsprechende Anschlagfunktion an einer Längswand übernehmen mußte.According to claim 2, the carrier body is designed as a substantially rectangular, folded on the narrow sides steel plate, which has a stop angle for a latch side surface on one long side. This stop angle also causes a substantial stiffening of the structure and relieves the rosette cap, which had to take over the corresponding stop function on a longitudinal wall in conventional constructions.

Die Verbindung von Griffhals und Riegel erfolgt gemäß Anspruch 3 unter Zwischenlage des Trägerkörpers durch eine Verbördelung oder Verschraubung in Axialrichtung und durch eine Formschluß-Mitnahme in Drehrichtung. Man erkennt, daß dies eine einfache Montage und dank hoher Festigkeit eine dauerhafte Gebrauchstüchtigkeit sichert.The connection of the handle neck and latch is carried out according to claim 3 with the interposition of the carrier body by crimping or screwing in the axial direction and by a form-fit entrainment in the direction of rotation. It can be seen that this ensures simple assembly and, thanks to its high strength, permanent serviceability.

Während der Griffhals in an sich bekannter Weise den Riegel durchragen und an ihm verbördelt sein kann, sieht die Erfindung laut Anspruch 4 alternativ vor, daß der Riegel mit einem insbesondere schwach konisch gestalteten Profilteil starr verbunden oder einstückig ist, das formschlüssig in eine gegengleiche Profilausnehmung des Griffhalses eingreift. Diese Ausführung eignet sich besonders für eine Schraubverbindung, die große Zug- und Druckkräfte bzw. -momente zuverlässig aufnimmt.While the handle neck can protrude through the bolt in a known manner and be flanged on it, the invention according to claim 4 alternatively provides that the bolt is rigidly connected or integrally with a particularly weakly conically shaped profile part, which is form-fitting in an opposite profile recess of the Handle neck engages. This version is particularly suitable for a screw connection that reliably absorbs large tensile and compressive forces or moments.

Nach Anspruch 5 weist die Rosette und/oder der Trägerkörper namentlich schmalseitig angeordnete Schraublöcher auf, so daß beide Bauteile zusammen an der Anschraubfläche befestigbar sind. Es ist jedoch auch möglich und erfindungsgemäß vorgesehen, nur den Trägerkörper anzuschrauben und die Rosette aufzuclipsen, die in solchem Falle als dekoratives Bauelement die Schraubbefestigung abdeckt.According to claim 5, the rosette and / or the support body, in particular, has screw holes arranged on the narrow side, so that both components can be fastened together on the screw-on surface. However, it is also possible and provided according to the invention to screw on only the carrier body and to clip on the rosette which, in such a case, covers the screw fastening as a decorative component.

Bei einer Handhabe mit einer bevorzugt halsparallelen Ausnehmung im Griffkopf zur Aufnahme einer Arretier-Einrichtung, die zur Ver- bzw. Entriegelung der Handhabe einen in die Rosette vorschiebbaren bzw. aus ihr zurückziehbaren Schließbolzen aufweist, ist gemäß Anspruch 6 ferner vorgesehen, daß der Trägerkörper zur Aufnahme des Schließbolzen-Endes neben der Führungsbohrung eine Öffnung mit einem Bereich hat, der wenigstens ungefähr mit der Seitenfläche des Riegels fluchtet, wenn dieser in seine Schließstellung ausgeschwenkt ist. Das Schließbolzen-Ende durchdringt außer der Rosette also auch den Trägerkörper an derart gewählter Stelle, daß der Riegel in seiner Schließstellung mit einer Seitenfläche an dem Schließbolzen anliegt, so daß der Griff nicht ohne vorherige Entriegelung betätigbar ist.In a handle with a preferably neck-parallel recess in the handle head for receiving a locking device which has a locking bolt that can be pushed into or removed from the rosette for withdrawing or locking the handle, according to claim 6 it is further provided that the carrier body for Receiving the locking pin end next to the guide bore has an opening with an area that is at least approximately flush with the side surface of the bolt when it is pivoted into its closed position. In addition to the rosette, the locking bolt end thus also penetrates the carrier body at a point selected in such a way that in its closed position the bolt rests with a side face on the locking bolt, so that the handle cannot be actuated without prior unlocking.

Sogenannte Kindersicherungen besitzen einen Schließbolzen, der durch eine Feder zur Schließstellung hin belastet wird. Bei einer damit ausgestatteten Handhabe sieht die Erfindung gemäß Anspruch 7 vor, daß der Schließbolzen im Griffkopf in einem Buchsenkörper geführt ist, an dem sich ein mit dem Schließbolzen-Oberteil gelenkig und/oder flexibel verbundenes Betätigungsorgan abstütz. Die gelenkige bzw. flexible Verbindung erlaubt es dabei, daß die Bewegungsrichtung des Schließbolzens von jener des Betätigungsorgans abweicht, wodurch ein erheblicher Platzgewinn erzielt werden kann. Besonders vorteilhaft ist es, wenn laut Anspruch 8 das Betätigungsorgan als parallel zur Griff-Außenfläche verstellbarer Schieber mit einem biegsamen Anschlußteil ausgebildet ist, das richtungsveränderlich an dem Oberteil des Schließbolzens angreift. Die Betätigung des Schiebers in Richtung des Griff-Hauptteils ist also Voraussetzung dafür, daß der Schließbolzen entgegen der Kraft seiner Feder etwa parallel zur Achse des Griffhalses zurückgezogen und damit entriegelt werden kann. Namentlich Kleinkinder und Behinderte werden diese zusätzliche, anders gerichtete Betätigung nicht ohne weiteres bewältigen können, was zu erhöhter Sicherheit in einem Raum bzw. Gebäude beiträgt.So-called child safety devices have a locking bolt which is loaded by a spring towards the closed position. In a handle equipped with this, the invention provides according to claim 7 that the locking pin is guided in the grip head in a socket body on which an articulated and / or flexible actuating member is supported with the upper locking pin part. The articulated or flexible connection allows the direction of movement of the locking bolt to deviate from that of the actuating member, whereby a considerable gain in space can be achieved. It is particularly advantageous if, according to claim 8, the actuating member is designed as a slide which can be adjusted parallel to the outer surface of the handle and has a flexible connecting part which acts on the upper part of the locking bolt in a directionally variable manner. The actuation of the slide in the direction of the main part of the handle is a prerequisite for the fact that the locking bolt can be pulled back against the force of its spring approximately parallel to the axis of the handle neck and thus unlocked. Small children and disabled people in particular will not be able to cope with this additional, different activity, which contributes to increased safety in a room or building.

Sehr vorteilhaft ist die Ausgestaltung von Anspruch 9, wonach das Anschlußteil ein mit dem Schieber einstückiges Kunststoff-Band mit verdicktem Ende ist, das insbesondere von einer nach außen verengten Queröffnung am Schließbolzen-Oberteil großenteils umschlossen wird. Das Band wird in erster Linie auf Zug beansprucht und leistet mit denkbar geringem Aufwand die Umlenkung der Betätigungsrichtung aus der Schließbolzenachse heraus. Die Formschluß-Verbindung ist sehr einfach gestaltet und weitestgehend verschleißfrei.The embodiment of claim 9 is very advantageous, according to which the connecting part is a plastic band with a thickened end, which is in one piece with the slider and is largely enclosed in particular by an outwardly narrowed transverse opening on the upper part of the locking bolt. The band is primarily subjected to tension and performs the deflection of the actuation direction out of the locking pin axis with very little effort. The positive connection is very simple and largely free of wear.

Günstig ist es ferner, wenn das Betätigungsorgan laut Anspruch 10 eine die Außenfläche des Griffes wenigstens geringfügig überragende Deckfläche hat, was das Anfassen erleichtert. Zusätzlich kann die Deckfläche gemäß Anspruch 11 zumindest teilweise aufgerauht, namentlich mit Pfeilstruktur geriffelt und nach außen insbesondere konkav gewölbt sein. Das gewährleistet eine sichere Betätigung durch den Daumen der zugreifenden Hand.It is also expedient if the actuating member has a cover surface which at least slightly projects beyond the outer surface of the handle, which makes it easier to touch. In addition, the top surface can be at least partially roughened, in particular corrugated with an arrow structure, and in particular can be concave to the outside. This ensures safe actuation by the thumb of the gripping hand.

Nach Anspruch 12 hat der Buchsenkörper einen das Betätigungsorgan führenden äußeren Flachteil, der in eine gegengleiche Aussparung des Griffkopfes eingepaßt und darin vorzugsweise stoffschlüssig befestigt ist. Der Flachteil lädt gegenüber einer Hülse des Buchsenkörpers in Richtung des Griff-Hauptteils aus und bietet daher dem Schieber die erforderliche Bewegungsmöglichkeit. Die Einpassung im Griffkopf wird vorzugsweise durch Einkleben gesichert. Die den Schließbolzen belastende Feder kann ihn laut Anspruch 13 in der Ausnehmung umschließen und sich am unteren Ende des Buchsenkörpers abstützen, also an dem erwähnten Hülsenteil. Auch diese Maßnahme trägt zu geringer Bauhöhe bei.According to claim 12, the socket body has an outer flat part guiding the actuating member, which is fitted into an opposite recess in the grip head and is preferably fixed integrally therein. The flat part protrudes towards a sleeve of the socket body in the direction of the main part of the handle and therefore offers the slide the necessary possibility of movement. The fit in the handle head is preferably secured by gluing. The spring loading the locking bolt can enclose it according to claim 13 in the recess and is supported on the lower end of the socket body, that is, on the sleeve part mentioned. This measure also contributes to a low overall height.

Eine andere Bauform mit einem Schließbolzen, der Bestandteil eines in der halsparallelen Ausnehmung des Griffkopfes angebrachten Schließzylinders ist, zeichnet sich laut Anspruch 14 dadurch aus, daß der Riegel von einer zusätzlichen inneren Platte gegenüber der Anschraubfläche abgestützt ist. Dadurch erzielt man eine besonders hohe Belastbarkeit und entsprechend lange Gebrauchsdauer. Zur Lagesicherung kann die innere Platte gemäß Anspruch 15 in Aussparungen des Trägerkörpers reichende Laschen sowie Schraublöcher aufweisen, welche mit jenen des Trägerkörpers fluchten. Vorzugsweise hat die nach Anspruch 16 aus Stahl bestehende Platte eine zentrische, dem Riegel zugekehrte Abkröpfung mit einer Bohrung, in der ein am Riegel anliegender Zwischenring sitzt. Sowohl das Ausmaß der Abkröpfung als auch die Bemessung des Zwischenringes erlauben eine gute Anpassung an die örtlich gegebenen Montage-Verhältnisse derart, daß der Riegel und der mit ihm festverbundene Griff eine zuverlässige Abstützung gegenüber der Anschraubfläche erhalten.Another design with a locking bolt, which is part of a locking cylinder attached in the neck-parallel recess of the handle head, is characterized according to claim 14 in that the bolt is supported by an additional inner plate against the screwing surface. This results in a particularly high load capacity and a correspondingly long service life. To secure the position, the inner plate can have tabs which extend into recesses in the carrier body and screw holes which are aligned with those of the carrier body. Preferably, the plate made of steel according to claim 16 has a central offset facing the bolt with a bore in which an intermediate ring bearing on the bolt is seated. Both the extent of the offset and the dimensioning of the intermediate ring allow a good adaptation to the local mounting conditions in such a way that the bolt and the handle firmly attached to it receive reliable support against the screwing surface.

Die Maßnahmen der Ansprüche 17 bis 19 gewährleisten eine einwandfreie Führung und damit Verdrehbarkeit des Riegels, der durch eine hochbelastbare Schraubbefestigung axialfest am Griffkopf anbringbar ist und damit die Handhabe sicher haltert. Dazu trägt es bei, wenn die Befestigungsschraube laut Anspruch 20 selbstschneidend in einem vorzugsweise schwach konisch ausgebildeten Sackloch verankerbar ist.The measures of claims 17 to 19 ensure proper guidance and thus rotatability of the bolt, which can be attached axially to the handle head by means of a heavy-duty screw fastening, and thus the handle holds securely. It helps if the fastening screw can be anchored in a preferably slightly conical blind hole according to claim 20.

Die in Fig. 1 allgemein veranschaulichte Handhabe besteht aus einem Griff 10, dessen Griffkopf 12 sich mit einem Griffhals 14, einer Schulter 16 und einem Vierkant 18 fortsetzt. Der Griff-Hauptteil kann mit (angedeuteten) Fingermulden versehen sein. Ein Ansatz 15 steht oben einseitig ab (vergl. Fig. 2b, 3b).The handle generally illustrated in FIG. 1 consists of a handle 10, the handle head 12 of which continues with a handle neck 14, a shoulder 16 and a square 18. The main part of the handle can be provided with (indicated) finger depressions. A shoulder 15 protrudes from one side at the top (see FIGS. 2b, 3b).

Ein weiterer Bestandteil ist eine Führungsbuchse 24, die in einer Bohrung 22 einer Rosette 20 zur Anlage kommt, welche allgemein kappenförmig ausgebildet und mit Schraublöchern 21 versehen ist. In die Rosette 20 ist eine Stahlplatte 30 einsetzbar, die ebenfalls im wesentlichen rechteckig geformt ist und an beiden Schmalseiten Stützwinkel 34 aufweist. Mittig ist eine Bohrung 32 vorgesehen, deren lichte Weite dem Einsatz-Durchmesser der flanschartig gestalteten Führungsbuchse 24 entspricht. An der Unterseite hat die Stahlplatte 30 eine Anlagefläche 35 für einen Riegel 26. Ferner weist sie nahe den Stützwinkeln 34 jeweils Schraublöcher 31 auf, welche den Schraublöchern 21 der Rosette 20 zugeordnet sind. Außerdem ist an einer Längsseite ein abgekanteter Anschlagwinkel 36 vorhanden, um Endstellungen des Riegels 26 zu begrenzen, der mittels des Griffes 10 schwenkbaren ist. Letzterer hat ein Vierkantloch 28 zur Aufnahme des Vierkants 18 beim Zusammenbau des Beschlages, wobei dessen axialfest/drehbare Verbindung durch eine Verbördelung 39 (Fig. 2a, 3a) gesichert wird.Another component is a guide bush 24, which comes into contact in a bore 22 of a rosette 20, which is generally cap-shaped and is provided with screw holes 21. A steel plate 30 can be inserted into the rosette 20, which is also essentially rectangular in shape and has support brackets 34 on both narrow sides. A bore 32 is provided in the center, the clear width of which corresponds to the insert diameter of the flange-shaped guide bush 24. On the underside, the steel plate 30 has a contact surface 35 for a bolt 26. Furthermore, it has screw holes 31 near the support angles 34, which are assigned to the screw holes 21 of the rosette 20. In addition, a beveled stop bracket 36 is provided on one long side in order to limit end positions of the bolt 26, which can be pivoted by means of the handle 10. The latter has a square hole 28 for receiving the square 18 when assembling the fitting, its axially fixed / rotatable connection being secured by a flange 39 (FIGS. 2a, 3a).

Aufbau und Funktion der montierten Einheit sind aus den Fig. 2a bis 2c und Fig. 3 bis 3c ersichtlich. In der verriegelten Stellung steht der Griff 10 schräg zur Rosette 20 so, daß der Ansatz 15 des Griffes und ein Arm bzw. Wölbteil 27 des Riegels die Rosette 20 an einer Längsseite überragen (Fig. 2b, 2c). Durch Hochschwenken des Griffes 10 erfolgt die Entriegelung (Fig. 3b, 3c). Man erkennt, daß der Griff 10 zur bequemen Handhabung eine Daumenauflage 11 im Bereich des Griffkopfes 12 haben kann. Wichtig ist, daß die Stahl-Unterplatte 30 zusammen mit der Rosette 20 den gesamten Beschlag an einer (nicht gezeichneten) Anschraubfläche abstütz, wobei die Schraublöcher 21, 31 nahe den Enden des kastenförmigen Gebildes angeordnet sind. Statt eines Lochpaares wie gezeichnet, können auch nahe den Ecken zwei Lochpaare vorgesehen sein, um noch größere Festigkeit der Schraubverbindung zu gewährleisten.The structure and function of the assembled unit can be seen from FIGS. 2a to 2c and FIGS. 3 to 3c. In the locked position, the handle 10 is at an angle to the rosette 20 so that the extension 15 of the handle and an arm or arch part 27 of the bolt project beyond the rosette 20 on one long side (FIGS. 2b, 2c). Unlocking takes place by pivoting the handle 10 upward (FIGS. 3b, 3c). It can be seen that the handle 10 can have a thumb rest 11 in the area of the handle head 12 for easy handling. It is important that the steel lower plate 30 together with the rosette 20 support the entire fitting on a (not shown) screwing surface, the screw holes 21, 31 being arranged near the ends of the box-shaped structure. Instead of a pair of holes as shown, two pairs of holes can also be provided near the corners in order to ensure even greater strength of the screw connection.

Fig. 4 zeigt in auseinandergezogener Darstellung die Einzelteil einer anderen Handhaben-Bauform, wobei der Griff 10 mit einer an der Rosette 20 und der Stahlplatte 30 wirksamen Kindersicherung versehen ist. Ferner befindet sich im Bereich des Griffkopfes 12 parallel zur Achse des Griffhalses 14 eine zylindrische Ausnehmung 54, an die zur Oberseite des Griffes 10 hin eine ovale Ausnehmung 19 anschließt. Diese Öffnungen dienen zur Aufnahme eines Buchsenkörpers 45, der im montierten Zustand mit einem Hülsenteil 46 in der Ausnehmung 54 sitzt, während ein Flachteil 55 in die Ausnehmung 19 eingepaßt und darin verklebt wird.Fig. 4 shows an exploded view of the individual part of another handle design, the handle 10 being provided with an effective child safety device on the rosette 20 and the steel plate 30. It is also located in Area of the handle head 12 parallel to the axis of the handle neck 14, a cylindrical recess 54, to which an oval recess 19 connects to the top of the handle 10. These openings serve to receive a socket body 45, which in the assembled state sits with a sleeve part 46 in the recess 54, while a flat part 55 is fitted into the recess 19 and glued therein.

Der Hülsenteil 46 hat am unteren Ende einen Führungsring 47 für einen Schließbolzen 40, dessen unteres Ende 41 in eine Loch 23 der Rosette und eine mit ihr fluchtende Loch 38 der Platte 30 vorschiebbar ist. Eine Druckfeder 48 wird auf dem Schlleßbolzen durch eine Sicherungsscheibe 49 gehalten, die in eine Ringnut 42 eingesetzt wird. Am Oberteil 43 des Schließbolzens 40 befindet sich eine nach außen verengte Querbohrung 44, in die ein verdicktes Ende 53 eines Anschlußbandes 52 einführbar ist. Das Band 52 ist einstückig mit einem Schieber 50, der eine aufgerauhte Deckfläche 51 hat.The sleeve part 46 has at the lower end a guide ring 47 for a locking bolt 40, the lower end 41 of which can be advanced into a hole 23 of the rosette and a hole 38 of the plate 30 aligned therewith. A compression spring 48 is held on the locking bolt by a locking washer 49 which is inserted into an annular groove 42. On the upper part 43 of the locking bolt 40 there is an outwardly narrowed transverse bore 44 into which a thickened end 53 of a connecting strap 52 can be inserted. The band 52 is in one piece with a slide 50, which has a roughened top surface 51.

Die zusammengebaute Einheit und ihre Funktion sind in den Fig. 5a bis 5c in verriegelter Stellung sowie in den Fig. 6a bis 6c in entriegelter Stellung ersichtlich. Wie man insbesondere aus Fig. 5a sieht, drückt die Feder 48 den Schließbolzen 40 mit seinem Ende 41 in die Löcher 23, 38 der Rosetten-Platten-Einheit 20/30. Ihr gegenüber kann der Griff 10 daher nicht verschwenkt werden. Bewegt man jedoch den Schieber 50 im Flachteil 55 des Buchsenkörpers 45 in der Richtung, welche die geriffelte Deckfläche 51 durch eine Pfeilstruktur andeutet, so zieht das Anschlußband 52 über die Formschluß-Verbindung 53/44 den Schließbolzen 40 entgegen der Kraft der Feder 48 nach oben und aus den Löchern 38, 23 heraus (Fig. 6a). Nun kann der Griff 10 in die offene Stellung verschwenkt werden (Fig. 6b). Wird der Schieber losgelassen, so zieht die Druckfeder 48 ihn und den Schließbolzen 40 wieder nach unten.The assembled unit and its function can be seen in FIGS. 5a to 5c in the locked position and in FIGS. 6a to 6c in the unlocked position. As can be seen in particular from FIG. 5a, the spring 48 presses the locking pin 40 with its end 41 into the holes 23, 38 of the rosette-plate unit 20/30. The handle 10 cannot therefore be pivoted in relation to it. However, if you move the slide 50 in the flat part 55 of the socket body 45 in the direction that indicates the corrugated cover surface 51 by an arrow structure, the connecting band 52 pulls the locking bolt 40 against the force of the spring 48 upward via the positive connection 53/44 and out of holes 38, 23 (Fig. 6a). The handle 10 can now be pivoted into the open position (FIG. 6b). If the slide is released, the compression spring 48 pulls it and the locking bolt 40 down again.

Die Bestandteile einer abschließbaren Handhabe sind in Fig. 7 dargestellt. Hierbei ist im Griffkopf 12 parallel zur Achse des Griffhalses 14 ein Schließzylinder 59 eingesetzt, der mit einem Schlüssel S betätigbar ist, um das untere Ende eines Schließbolzens 40 vor- bzw. zurückzubewegen. Die Rosetten-Platten-Einheit 20/30 nimmt mittig die Führungsbuchse 24 auf, neben der die Löcher 23, 38 dem Schließbolzen 40/41 zugeordnet sind.The components of a lockable handle are shown in Fig. 7. Here, a locking cylinder 59 is inserted in the handle head 12 parallel to the axis of the handle neck 14, which can be actuated with a key S in order to move the lower end of a locking bolt 40 back and forth. The rosette-plate unit 20/30 receives the guide bush 24 in the center, next to which the holes 23, 38 are assigned to the locking bolt 40/41.

Der Riegel 26 hat einen Profilteil 29, der als Vier- oder Mehrkant ausgebildet sein kann und zum Einpassen in eine gegengleiche Profilausnehmung 56 im Griffhals 14 bestimmt ist. Die Ausnehmung 56 setzt sich mit einem gleichfalls schwach konisch gestalteten Sackloch 57 fort. Der Riegel 26 samt Profilteil 29 ist axial von einem Durchgangsloch 25 durchsetzt, das bodenseitig in eine Vertiefung 72 mündet. Letztere ist von einem Wulst 71 umschlossen, den eine ringförmige Vertiefung 73 umgibt. Diese dient der Aufnahme eines Zwischenringes 66, welcher in einer Bohrung 62 einer inneren Stahlplatte 60 sitzt, und zwar in einem mittigen Bereich, der durch ein Abkröpfung 63 zum Riegel 26 hin angehoben ist. An den Schmalenden hat die innere Stahlplatte 60 Schraublöcher 61.The latch 26 has a profile part 29, which can be designed as a square or polygon and for fitting into an opposite profile recess 56 in the handle neck 14 is determined. The recess 56 continues with an equally weakly conical blind hole 57. The bolt 26 together with the profile part 29 is axially penetrated by a through hole 25 which opens into a recess 72 on the bottom side. The latter is enclosed by a bead 71 which is surrounded by an annular recess 73. This serves to receive an intermediate ring 66, which is seated in a bore 62 of an inner steel plate 60, specifically in a central region, which is raised toward the bolt 26 by an offset 63. The inner steel plate 60 has screw holes 61 at the narrow ends.

Unter Zwischenlage einer Wellfeder 64 ist eine Stufenscheibe 65 mittels einer Schraube 67 montierbar, welche das Durchgangsloch 25 durchsetzt und in das Sackloch 57 einziehbar ist, so daß die Bauteile 60, 26/29, 20/30 an den Griffhals 14 des Griffkopfes 12 gepreßt werden. Teilweise vormontiert sind die Unterseiten der hauptsächlichen Bauelemente bzw. Baugruppen in Fig. 8 dargestellt, und zwar in Zuordnung zu den entsprechenden Bestandteilen in Fig. 7.With the interposition of a corrugated spring 64, a step washer 65 can be mounted by means of a screw 67, which passes through the through hole 25 and can be drawn into the blind hole 57, so that the components 60, 26/29, 20/30 are pressed onto the handle neck 14 of the handle head 12 . The undersides of the main components or assemblies are shown partially pre-assembled in FIG. 8, specifically in association with the corresponding components in FIG. 7.

Zusammengebaut ist der Beschlag in Fig. 9a bis 9c in verriegelter Stellung sowie in Fig. 10a bis 10c in entriegelter Position gezeichnet. Man erkennt, daß die innere Stahlplatte 60 sich an der (nicht dargestellten) Anschraubfläche abstützt und damit ein Widerlager für den Riegel 26 und den mit ihm verschraubten Griff 10 bietet. Dabei sorgt das Ineinandergreifen der Bauteile 65, 64, 66, 26, 24, 16 für exakte Zentrierung und freie Drehbarkeit bei geringstem Axialspiel. In der Sperrstellung (Fig. 9a) des Schließbolzens 40 wird der Griff 10 in der Position von Fig. 9b gehalten, wobei der Riegel 26 mit seinem Arm bzw. Wölbteil 27 und der Ansatz 15 seitlich über den Rosettenkörper 20 vorstehen. Sobald das Schließbolzen-Ende 41 durch Betätigung des Schlüssels S in den Schließzylinder 59 zurückgezogen ist (Fig. 10a), kann der so entriegelte Griff 10 hochgeschwenkt werden (Fig. 10b). Dabei findet der Riegel 26 - welcher in Fig. 8 (Mitte) in ausgeschwenkter Position dargestellt ist, wobei der Arm bzw. Wölbteil 27 einen Seitenschlitz 74 der Rosette 20 durchsetzt - mit einer Seitenfläche 68 nun eine Drehbegrenzung durch Anlage am Anschlagwinkel 36. Wie man Fig. 8 entnimmt, ist der Riegel 26 allgemein spitz-oval gestaltet, so daß die Seitenfläche 68 gewissermaßen auf dem Anschlagwinkel 36 abrollt. Dieser geht mit Ausstanzungen 37 in den Hauptteil der Platte 30 über, um Kerbwirkungen zu verhindern. Dasselbe gilt für Ausstanzungen 70 beiderseits von Laschen 69, welche in Aussparungen 33 der Stützwinkel 34 einzugreifen bestimmt sind und Schraublöcher 61 aufweisen, welche im montierten Zustand mit den Schraublöchern 21, 31 der Rosetten-Platten-Einheit 20/30 fluchten.Assembled, the fitting is shown in the locked position in FIGS. 9a to 9c and in the unlocked position in FIGS. 10a to 10c. It can be seen that the inner steel plate 60 is supported on the screwing surface (not shown) and thus offers an abutment for the bolt 26 and the handle 10 screwed to it. The meshing of components 65, 64, 66, 26, 24, 16 ensures exact centering and free rotation with the least amount of axial play. In the locked position (FIG. 9a) of the locking bolt 40, the handle 10 is held in the position of FIG. 9b, the bolt 26 with its arm or arch part 27 and the shoulder 15 projecting laterally beyond the rosette body 20. As soon as the locking bolt end 41 has been retracted into the locking cylinder 59 by actuating the key S (FIG. 10a), the handle 10 unlocked in this way can be pivoted upward (FIG. 10b). Here, the bolt 26 - which is shown in Fig. 8 (center) in the pivoted-out position, the arm or arch part 27 penetrating a side slot 74 of the rosette 20 - with a side surface 68 now a rotation limitation by abutment on the stop bracket 36. How to Fig. 8 reveals, the latch 26 is generally pointed-oval, so that the side surface 68 rolls to a certain extent on the stop bracket 36. This passes into the main part of the plate 30 with punchings 37 in order to prevent notching effects. The same applies to punchings 70 on both sides of tabs 69, which are intended to engage in recesses 33 of the support bracket 34 and have screw holes 61, which in the assembled state are aligned with the screw holes 21, 31 of the rosette-plate unit 20/30.

Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt; vielmehr sind zahlreiche Abwandlungen möglich. Man erkennt aber, daß die beschriebene Drehhandhabe in erster Linie einen Drehgriff 10 betrifft, dessen Hals 14 an einer kästchenförmigen Rosette 20 axialfest/drehbar gelagert und im Inneren mit einem ausschwenkbaren Riegel 26 drehfest verbunden ist, weist einen an der Anschraubfläche abgestützten Trägerkörper 30 auf, der seinerseits eine Anlagefläche 35 für den Riegel 26 hat und eine abgekantete Stahlplatte 30 ist, die einen Anschlagwinkel 36 für eine Seitenfläche 68 eines spitz-ovalen Riegelteils hat. Der Riegel 26 kann mit einem konischen Profilteil 29 starr verbunden oder einstückig sein, das formschlüssig in eine Profilausnehmung 56 des Griffhalses 14 eingreift. Eine Kindersicherung hat einen gefederten Schließbolzen 40 in einem Buchsenkörper 45, in dem ein parallel zur Griff-Außenfläche verstellbarer Schieber 50 mit einem biegsamen Anschlußteil 52 geführt ist, das richtungsveränderlich an dem Schließbolzen-Oberteil 43 angreift und eine geriffelte, konkav gewölbte Deckfläche 51 hat. Der Riegel 26 kann von einer inneren Stahlplatte 60 gegenüber der Anschraubfläche abgestützt und samt Profilteil 29 mittels einer Schraube 67 axial fixierbar sein, die vorzugsweise selbstschneidend im Griffkopf 12 verankerbar ist.The invention is not limited to the illustrated embodiments; rather, numerous modifications are possible. It can be seen, however, that the rotary handle described relates primarily to a rotary handle 10, the neck 14 of which is axially fixed / rotatable on a box-shaped rosette 20 and is non-rotatably connected on the inside to a pivotable bolt 26, has a support body 30 supported on the screw-on surface, which in turn has a contact surface 35 for the bolt 26 and is a folded steel plate 30 which has a stop angle 36 for a side surface 68 of a pointed oval bolt part. The bolt 26 can be rigidly connected or integrally with a conical profile part 29, which engages in a form-fitting manner in a profile recess 56 of the handle neck 14. A child safety device has a spring-loaded locking pin 40 in a socket body 45, in which a slide 50, which can be adjusted parallel to the outer surface of the handle, is guided with a flexible connecting part 52, which acts on the locking pin upper part 43 in a directionally variable manner and has a corrugated, concavely curved top surface 51. The bolt 26 can be supported by an inner steel plate 60 with respect to the screw-on surface and can be axially fixed together with the profile part 29 by means of a screw 67, which can preferably be anchored in the handle head 12 in a self-tapping manner.
