Description

Die Erfindung betrifft einen Bausatz einer mechanischen Rückstellhilfe für die Tastatur von mechanischen Tasteninstrumenten, insbesondere Orgeln, mit einer Anordnung zum Ein- und Ausschalten dieser Rückstellhilfe.The invention relates to a kit of a mechanical reset aid for the keyboard of mechanical keyboard instruments, in particular organs, with an arrangement for switching this reset aid on and off.

Orgeln der gemäß Oberbegriff genannten Gattung weisen zum Zwecke der Tonerzeugung sogenannte Windladen auf, auf denen die Labial- oder Zungenpfeifen sitzen und entsprechend des Tastenspiels des Organisten von Luft durchströmt werden, was mittels einer mechanischen Traktur erfolgt. Hierbei ist die Taste über eine Brücke und gegebenenfalls Seil-, Draht- oder Holzzügen mit den die Luftzufuhr sperrenden oder freigebenden Ventilen verbunden.
Diese können in der zuvor genannten Windlade integriert sein, welche ständig von Luft durchströmt ist.Organs of the type mentioned according to the preamble have so-called wind chests for the purpose of sound generation, on which the labial or reed pipes sit and air flows through according to the organist's keyboard play, which is done by means of a mechanical action. Here, the button is connected to the valves that block or release the air supply via a bridge and, if necessary, cable, wire or wooden cables.
These can be integrated in the above-mentioned wind chest, through which air flows continuously.

Eine Orgel kann zwischen einigen hundert und mehreren tausend Pfeifen haben. Der Organist sitzt hierbei am Spieltisch, der direkt oder weit beabstandet vom Pfeifenbau angeordnet ist. Dieser Spieltisch hat meist mehrere Manuale und eine Fußpedalreihe. Hierbei ist jedem Manual eine je nach Größe der Orgel vorbestimmte Anzahl von Registern zugeordnet. Die Töne der Orgel erklingen, wenn eines oder mehrere Register offen sind und dadurch der Luft den Zutritt der zum Register gehörenden Pfeifenreihe freigeben. Um den vollen Klang einer Orgel zu erreichen, kann der Organist mehrere, in der Regel zwei bzw. drei Manuale aneinanderkoppeln, womit alle Töne aller Manuale erklingen. Er kann auch verschiedene Register zusammenstellen, so daß er eine Mischung von Tönen erhält usw.An organ can have between a few hundred and several thousand pipes. The organist sits at the game table, which is arranged directly or at a distance from the pipe construction. This game table usually has several manuals and a foot pedal row. Each manual is assigned a predetermined number of registers depending on the size of the organ. The tones of the organ sound when one or more registers are open, thereby allowing air to enter the row of pipes belonging to the register. In order to achieve the full sound of an organ, the organist can couple several, usually two or three manuals together, so that all tones of all manuals are heard. He can also put together different registers so that he gets a mix of tones, etc.

Während nun die Entwicklung der Orgel in zwei verschiedene Richtungen ging, und zwar die Entwicklung des elektropneumatischen Werks und der mechanischen Traktur mit Schleifladen ergab sich im Laufe dieser Zeit bei der mechanischen Traktur das Problem der durch den Organisten aufzubringenden Druckes auf die Tasten bzw. des mechanischen Problems der Rückstellung der Tasten. Hierbei konnten durch den Einsatz des sogenannten "Barker-Hebels" sehr gute Ergebnisse hinsichtlich des Tastendruckes erzielt werden.While the development of the organ went in two different directions, namely the development of the electropneumatic work and the mechanical action with a sliding shutter, the problem of the pressure to be applied by the organist on the keys or the mechanical action arose during the mechanical action Problems resetting the buttons. The use of the so-called "Barker lever" made it possible to achieve very good results when pressing a button.

Jedoch auch hier ist beim Tastenspiel des Organisten mit einer Anhäufung von Repetitionen eine Grenze gesetzt, die nicht jedes Spiel eines beliebigen Orgelstückes zuläßt. Insbesondere dann, wenn ein freistehender Spieltisch derart positioniert ist, daß zwischen Taste und Spielventil in der Windlade bzw. Wellenbrett Abstraktenlängen über mehrere Meter (z. B. 8 Meter) erforderlich sind. Die beim "Barker-Hebel" eingesetzten Federn müssen hierbei entsprechend stark ausgebildet sein, damit durch die langen Abstrakten die Taste schnell genug zurückgestellt wird und somit eine gute Repetition erreicht wird. Der Tastendruck am Spieltisch wird dann jedoch zu groß. Besonders bei der romantischen Literatur ist ein leichter, gleichmäßiger Tastendruck bei schneller Repetition gefragt.However, here, too, there is a limit to the organist's keyboard play with an accumulation of repetitions, which does not allow every play of any organ piece. Especially when a free-standing game table is positioned such that abstract lengths of several meters (e.g. 8 meters) are required between the button and the game valve in the wind chest or wave board. The springs used in the "Barker lever" must be strong enough so that the key is reset quickly enough due to the long abstracts and thus a good repetition is achieved. The button press on the gaming table then becomes too large. With romantic literature in particular, a light, even keystroke with fast repetition is required.

Man ist daher dazu übergegangen, einen Elektromagneten in der Windelade bzw. unterhalb der Windlade einzusetzen. Diese haben jedoch den Nachteil, daß sie nur ein- oder ausschalten. Beim Einschalten der Magnete öffnet das Ventil explosionsartig welches für die Ansprache der Pfeife (Einschwingvorgang) nachteilig ist. Der Organist Kann somit das Ansprechen der Pfeife durch sein Spiel nicht beeinflussen, da der Magnet wie gesagt nur ein- oder ausschaltet.It has therefore started to use an electromagnet in the diaper drawer or below the wind drawer. However, these have the disadvantage that they only switch on or off. When the magnets are switched on, the valve opens explosively, which is disadvantageous for the response of the whistle (settling process). The organist can thus respond to the pipe through his play do not influence, as the magnet only switches on or off, as I said.

Ferner sind die mit dem "Barker-Hebel" bestückten Orgeln nur mit diesem bespielbar. Ein Umschalten auf rein manuelles Spiel ohne "Barker-Hebel" ist mit den bekannten Orgeln nicht möglich.Furthermore, the organs equipped with the "Barker lever" can only be played with this. Switching to a purely manual game without "Barker lever" is not possible with the known organs.

Durch die Verwendung eines "Barker-Hebels" bzw. einer "Barker-Maschine" kann der Organist die Ventile, welche für das Ansprechen der Pfeifen zuständig sind, zwar fast synchron zum Tastendrücken steuern; er kann also die Ansprechgeschwindigkeit je nach Ausdrucksdynamik der Interpretation optimieren. Dieser "Barker-Hebel" ermöglicht somit eine fast synchrone Steuerung der Tonventile in der Windlade wie eine rein mechanische Traktur. Jedoch besteht der verbleibende Nachteil, daß das bereits bekannte "Barker-System" immer unmittelbar, bei Auschöpfung aller Vorteile dieses Systems, direkt am Spieltisch (bei den Tasten) oder sehr naheliegend eingebaut werden muß, denn alleine für den Tastendruck ist die Feder am entsprechenden Sperrventil zuständig, welche entsprechend der Vergrößerung der Entfernung der "Barker-Maschine" vom Spieltisch immer stärker ausgelegt werden muß, damit die Spieltraktur gut repetiert, was wiederum den Tastendruck beeinträchtigt.By using a "Barker lever" or a "Barker machine", the organist can control the valves which are responsible for responding to the pipes almost synchronously with the key press; he can thus optimize the response speed depending on the expression dynamic of the interpretation. This "Barker lever" enables almost synchronous control of the sound valves in the wind chest like a purely mechanical action. However, there is the remaining disadvantage that the already known "Barker system" must always be installed immediately, when all the advantages of this system have been exhausted, directly at the gaming table (at the keys) or very obvious, because the spring is only at the appropriate key pressure Locking valve responsible, which must be interpreted more and more in accordance with the increase in the distance of the "Barker machine" from the game table, so that the game action repeats well, which in turn affects the keystroke.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Bausatz gemäß des Oberbegriffs zu schaffen, der es erlaubt, bei einem freistehenden Spieltisch, wo zwischen Taste und Spielventil in der Windlade bzw. Wellenbrett Abstraktenlängen über mehrere Meter vorliegen und ein sogenanntes "Barker-System" integriert ist oder einsetzbar ist, diesen Bausatz einzusetzen, so daß die dem "Barker-Hebel" zugrundeliegende Federkraft unberücksichtigt bleiben kann und wahlweise diesen Bausatz für die Rückstellhilfe zu aktivieren bzw. auszuschalten.The invention is therefore based on the object of creating a kit according to the preamble which allows, in a free-standing game table, where there are abstract lengths of several meters between a button and a game valve in the wind chest or wave board So-called "Barker system" is integrated or can be used to use this kit so that the spring force on which the "Barker lever" is based can be disregarded and optionally activate or deactivate this kit for the reset aid.

Diese Aufgabe wird erfindungsgemäß durch einen Bausatz einer mechanischen Rückstellhilfe für die Tastatur von mechanischen Tasteninstrumenten, insbesondere Orgeln, mit einer Anordnung zum Ein- und Ausschalten des Barker-Systems mit Rückstellhilfe, gemäß des kennzeichnenden Teils des Hauptanspruchs 1 gelöst.This object is achieved according to the invention by a kit of a mechanical reset aid for the keyboard of mechanical keyboard instruments, in particular organs, with an arrangement for switching the Barker system on and off with a reset aid in accordance with the characterizing part of main claim 1.

Besondere Ausführungsmerkmale der Erfindung sind in den Unteransprüchen gekennzeichnet, hierbei ist vorgesehen, daß der Bausatz aus einem über den Arbeitsweg eines, in einem Gehäuse integrierten, pneumatisch betriebenen Arbeitsbalges und über die Schließ- und Öffnungsbewegung von Sperrventilen aktivierbaren Hebelgelenk sowie Steuernocken besteht, und hierbei das Hebelgelenk einen die Tastatur in Ausgangsstellung bringenden Zug aufweist und unterhalb des Arbeitsbalgs ein mit dem Ventil in Verbindung stehender, durch dieses und durch das Hebelgelenk verstellbarer Steuernocken vorgesehen ist, wobei unterhalb des Gehäuses ein mit der Tastatur in Verbindung stehender, das Ventil aktivierbarer und mit einem Zugarm in Eingriff bringbarer Hebel angeordnet ist.Special features of the invention are characterized in the subclaims, here it is provided that the kit consists of a lever joint and control cams which can be activated via the working path of a pneumatically operated working bellows integrated in a housing and via the closing and opening movement of check valves, and here that Lever joint has a pull bringing the keyboard into the starting position and below the working bellows there is a control cam connected to the valve, which can be adjusted by this and through the lever joint, a valve connected to the keyboard being connected to the valve, which can be activated and having a Pull arm engaging lever is arranged.

Bei einer besonders bevorzugten Ausführungsform der Erfindung besteht das Hebelgelenk aus einem annähernd rechtwinkelig auf dem Arbeitsbalg angeordnetem Stellstab, Lagerbock, Federträger, Feder und Federhebel mit Einstellnocken sowie einem, auf einer Balghubbegrenzung gelagertem Winkelhebel mit Anschlagkopf.In a particularly preferred embodiment of the invention, the lever joint consists of an actuating rod arranged approximately at right angles on the working bellows, bearing block, spring support, spring and spring lever with adjusting cams and an angle lever with stop head mounted on a bellows stroke limitation.

Durch diese Anordnung des Hebelgelenkes wird die Hubbewegung des Arbeitsbalgs ausgenutzt. Die Achse des Stellstabes verläuft hierbei durch die Auflagefläche des Winkelhebels, wobei die Balghubbegrenzung, die einen Lagerbock zur Aufnahme des Winkelhebels trägt, U-förmig ausgebildet ist und mit seinen nach unten ragenden Schenkeln derart an dem unterhalb des Balkens vorgesehenen Luftströmkanals angeordnet ist, daß zwischen dem Quersteg der Balghubbegrenzung und der Oberfläche des Balgs ein Freiraum gebildet ist, in dem sich der Balg frei bewegen kann.This arrangement of the lever joint makes use of the lifting movement of the working bellows. The axis of the control rod runs through the support surface of the angle lever, the bellows stroke limitation, which carries a bearing block for receiving the angle lever, is U-shaped and with its downwardly projecting legs is arranged on the air flow channel provided below the beam in such a way that between a free space is formed in the crosspiece of the bellows stroke limitation and the surface of the bellows, in which the bellows can move freely.

Der Winkelhebel ist hierbei um die Achse des Lagerbocks drehbar gelagert und mit seinem, die Auflagefläche aufweisenenden Hebelteil in den Balghubbereich über den Kopfbereich des Stellstabes einragend angeordnet.The angle lever is in this case rotatably mounted about the axis of the bearing block and is arranged with its lever part, which has the bearing surface, projecting into the bellows stroke region above the head region of the adjusting rod.

Das andere Ende des Winkelhebels ragt hierbei in den Eingriffsbereich des Federhebels ein, wobei an diesem Hebelteil ein Anschlagkopf angeordnet ist. Zum Zwecke der Distanzvariierung zwischen Hebelteil und Federhebel ist der Anschlagkopf verstellbar bzw. drehbar ausgebildet. Dies kann in einem besonderen Ausführungsbeispiel der Erfindung mittels eines Gewindestabes erfolgen.The other end of the angle lever protrudes into the engagement area of the spring lever, a stop head being arranged on this lever part. For the purpose of varying the distance between the lever part and the spring lever, the stop head is adjustable or rotatable. In a special embodiment of the invention, this can be done by means of a threaded rod.

Zwischen der Innenfläche des Federträgers und der Innenfläche des Federhebels ist eine Rückstellfeder vorgesehen.A return spring is provided between the inner surface of the spring support and the inner surface of the spring lever.

Der auf der Oberfläche des Balgs aufliegende Lagerbock weist hochragend den Federträger auf und sieht im Bereich des über die Stirnseite des Balgs überragenden Lagerbockteils eine durch den Federhebel durchdrungene Aussparung auf.Zur Lagerung des Federhebels ist durch den Lagerbock eine senkrecht zum Federhebel verlaufende Drehachse angeordnet. Ferner sieht der Lagerbock zum Durchlaß des mit der Taste verbundenen Zuges eine Bohrung oder dergleichen vor.The bearing block resting on the surface of the bellows has a protruding spring support and, in the area of the bearing block part projecting beyond the end face of the bellows, has a recess penetrated by the spring lever. Furthermore, the bearing block provides a bore or the like for the passage of the train connected to the key.

Ein weiteres besonderes Merkmal der Erfindung besteht darin, daß der Eintellnocken des Federhebels kegelförmig ausgebildet ist, wobei die größere Grundfläche zum Federhebel hinweisend angeordnet ist und hierbei in einen im Querschnitt kleineren Zylinderkörper übergeht, so daß ein Eingriffsbereich für den Steuernocken gebildet ist. Der Einstellnocken ist hierbei verstellbar ausgebildet. Der Steuernocken ist mittels einer Drehachse unterhalb des Balgs axial fixiert und steht über ein Zug mit dem Sperrventil in Verbindung, wobei dieser Zug in einen Achspunkt des Steuernockens führt und dieser bei Bewegung des Ventils eine Kreisbahn um die Achse der Axialfixierung beschreitet.Another special feature of the invention is that the adjusting cam of the spring lever is conical, the larger base being arranged pointing towards the spring lever and in this case merging into a cylinder body with a smaller cross section, so that an engagement area for the control cam is formed. The adjustment cam is designed to be adjustable. The control cam is axially fixed below the bellows by means of an axis of rotation and is connected to the shut-off valve via a train, this train leading to an axis point of the control cam and following a circular path around the axis of the axial fixation when the valve moves.

Der Steuernocken weist eine in den Eingriffsbereich des Einstellnockens einragbare Nase auf.The control cam has a nose which can be protruded into the engagement area of the adjusting cam.

Die Anordnung zur Ein- und Ausschaltung des erfindungsgemäßen Bausatzes kennzeichnet sich durch einen Hebel, der in einer höhenverfahrbaren Aufnahmeleiste drehbar gelagert ist. Der Zugarm ist hierbei als einarmiger Hebel unterhalb des Gehäuses gelagert und mit dem Hebel durch einen Zug distanzvariabel verbunden. Hierbei greift ein Hebelbereich des Hebels bei aktivierter Stellung in den Eingriffsbereich eines Winkelhebels zur Aktivierung eines Sperrventils, wobei der Winkelhebel unterhalb des Gehäuses drehbar gelagert ist.The arrangement for switching the kit according to the invention on and off is characterized by a lever which is rotatably mounted in a height-adjustable mounting bar. The pull arm is mounted as a one-armed lever below the housing and with the lever connected variable distance by a train. In this case, a lever area of the lever engages in the engagement area of an angle lever for activating a check valve when the position is activated, the angle lever being rotatably mounted below the housing.

Anhand den beigefügten Zeichnungen wird die Erfindung nun näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawings.

Zunächst werden die Bestandteile des erfindungsgemäßen Bausatzes näher beschrieben. Dieser besteht aus einem über den Arbeitsweg eines, in einem Gehäuse 2 integrierten, pneumatisch betriebenen Arbeitsbalg 3 und über die Schließ- und Öffnungsbewegung von Sperrventilen 4,5 aktivierbaren Hebelgelenk 6 sowie Steuernocken 7. Auf dem Arbeitsbalg 3 ist ein Stellstab 12 angeordnet. Dessen Achse 21 führt durch den Auflagebereich 22 eines Winkelhebels 19, so daß der Kopfbereich 33 des Stellstabes 12 mit der Auflagefläche 22 in Verbindung tritt.First, the components of the kit according to the invention are described in more detail. This consists of a lever joint 6 and control cams 7 which can be activated via the working path of a pneumatically operated working bellows 3 integrated in a housing 2 and via the closing and opening movement of blocking valves 4, 5 and control cams 7. An adjusting rod 12 is arranged on the working bellows 3. Whose axis 21 leads through the support area 22 of an angle lever 19, so that the head area 33 of the actuating rod 12 comes into contact with the support surface 22.

Das Hebelgelenk 6 ist auf einem Lagerbock 29 aufgesetzt und um die Achse 30 drehbar. Der Lagerbock 29 selbst ist auf einer Balghubbegrenzung 18 angeordnet. Das Hebelgelenk 6 besteht aus einem Winkelhebel 19 mit einem Hebelteil 31, das in den Balghubbereich 32 über den Kopfbereich 33 des Stellstabes 12 einragt. Das andere Hebelteil 37 des Winkelhebels 19 weist einen Anschlagkopf 20 auf, dessen Achse 34 durch den Eingriffsbereich 35 eines Federhebels 16 verläuft. Die Balghubbegrenzung 18 ist vorzugsweise U-förmig ausgebildet und weist zwei nach unten ragende Schenkel 23 und 24 auf, zwischen denen der Balg 3 durchgeführt ist.
Die Schenkel 23 und 24 sind am Luftströmkanal 25 befestigt und haben keine Verbindung mit dem Balg 3. Der Quersteg 26 der Balghubbegrenzung 18 dient hierbei als oberste Begrenzung für die Bewegung des Balgs 3, wobei zwischen Quersteg 26 und Oberfläche 27 des Balgs 3 ein Zwischenraum 28 gebildet ist, der vorzugsweise mit einem hier nicht näher beschriebenen Filz oder ähnlichem ausgefüllt ist, so daß eine Dämpfung erreicht wird. Auf dem Balg 3 ist ein Lagerbock 13 angeordnet, der einen Federträger 14 und einen Federhebel 16 aufweist. Zwischen den Innenflächen 40 und 41 des Federträgers 14 und des Federhebels 16 ist eine Feder 15 positioniert. Der Winkelhebel 19 besitzt ein Hebelteil 37 mit einem Anschlagkopf 20, wobei dessen Achse 34 durch den Eingriffsbereich 35 des Federhebels 16 verläuft. Der Anschlagkopf 20 ist zum Zwecke der Distanzvariierung zwischen Hebelteil 37 und Federhebel 16 verstellbar bzw. drehbar ausgebildet. Dies kann z. B. durch ein Innengewinde zum Eingriff eines die Achse 34 bildenden Gewindestabes erfolgen.The lever joint 6 is placed on a bearing block 29 and rotatable about the axis 30. The bearing block 29 itself is arranged on a bellows stroke limiter 18. The lever joint 6 consists of an angle lever 19 with a lever part 31 which protrudes into the bellows stroke area 32 via the head area 33 of the actuating rod 12. The other lever part 37 of the angle lever 19 has a stop head 20, the axis 34 of which extends through the engagement region 35 of a spring lever 16. The bellows stroke limiter 18 is preferably U-shaped and has two legs 23 and 24 projecting downwards, between which the bellows 3 is passed.
The legs 23 and 24 are fastened to the air flow channel 25 and have no connection to the bellows 3. The cross bar 26 of the bellows stroke limiter 18 serves here as the uppermost limit for the movement of the bellows 3, with a space 28 between the cross bar 26 and the surface 27 of the bellows 3 is formed, which is preferably filled with a felt or the like not described here, so that damping is achieved. A bearing block 13 is arranged on the bellows 3 and has a spring support 14 and a spring lever 16. A spring 15 is positioned between the inner surfaces 40 and 41 of the spring support 14 and the spring lever 16. The angle lever 19 has a lever part 37 with a stop head 20, the axis 34 of which extends through the engagement region 35 of the spring lever 16. The stop head 20 is adjustable or rotatable for the purpose of varying the distance between the lever part 37 and the spring lever 16. This can e.g. B. by an internal thread for engaging a threaded rod forming the axis 34.

Der Lagerbock 13, der auf dem Balg 3 aufgelegt ist, ragt über die Stirnseite 42 des Balgs 3 heraus wobei in dem Lagerbock 43 eine durch den Federhebel 16 durchdrungene Aussparung 44 vorgesehen ist. Zur Lagerung des Federhebels 16 im Lagerbock 13 ist eine senkrecht zum Federhebel 16 verlaufende Drehachse 45 im Lagerbock 13 vorgesehen. Zum Zwecke des Durchlassens eines Zuges 8 weist der Lagerbock 13 eine Bohrung oder dergleichen auf.The bearing block 13, which is placed on the bellows 3, protrudes beyond the end face 42 of the bellows 3, a recess 44 penetrated by the spring lever 16 being provided in the bearing block 43. To support the spring lever 16 in the bearing block 13, an axis of rotation 45 running perpendicular to the spring lever 16 is provided in the bearing block 13. For the purpose of passing a train 8, the bearing block 13 has a bore or the like.

Der Federhebel 16 weist am bodenseitigen Ende einen Einstellnocken 17 auf, der vorzugsweise kegelförmig ausgebildet ist.The spring lever 16 has an adjusting cam 17 at the bottom end, which is preferably conical.

Die größere Grundfläche 47 des Einstellnockens 17 weist zum Federhebel 16 hin und geht in einen im Querschnitt kleineren Zylinderkörper 48 über, so daß ein Eingriffsbereich 49 gebildet ist. Auch dieser Einstellnocken 17 ist mittels eines Gewindestabes 50 verstellbar ausgebildet. Der Steuernocken 7 ist mittels einer Drehachse 51 unterhalb des Balgs 3 axial fixiert und steht über einen Zug 62 mit dem Sperrventil 4 in Verbindung, wobei der Zug 62 in einem Achspunkt 53 des Steuernockens 7 führt und diese bei Bewältigung des Ventils 4 eine Kreisbahn 54 um die Achse 51 beschreitet. Der Steuernocken 7 weist eine in den Eingriffsbereich 49 des Einstellnockens 17 einragbare Nase 55 auf.The larger base area 47 of the adjusting cam 17 points towards the spring lever 16 and merges into a cylinder body 48 with a smaller cross section, so that an engagement region 49 is formed. This setting cam 17 is also adjustable by means of a threaded rod 50. The control cam 7 is axially fixed below the bellows 3 by means of an axis of rotation 51 and is connected to the shut-off valve 4 via a train 62, the train 62 leading in an axis point 53 of the control cam 7 and this orbiting around the circular path 54 when the valve 4 is mastered the axis 51 treads. The control cam 7 has a nose 55 which can be inserted into the engagement region 49 of the adjusting cam 17.

Der Hebel 9 ist in einer höhenverfahrbaren Aufnahmeleiste 56 drehbar gelagert. Der Zugarm 10 ist als einarmiger Hebel ausgebildet und unterhalb des Gehäuses 2 gelagert und mit dem Hebel 9 durch den Zug 8 distanzvariabel verbunden. Der Hebelbereich 57 des Hebels 9 ragt bei aktivierter Stellung in den Eingriffsbereich 48 des Winkelhebels 59 ein, wobei das Ventil 4/5 aktiviert wird, wobei der Winkelhebel 59 unterhalb des Gehäuses drehbar gelagert ist.The lever 9 is rotatably mounted in a height-adjustable receiving bar 56. The pull arm 10 is designed as a one-armed lever and is mounted below the housing 2 and connected to the lever 9 by the pull 8 with variable distances. When activated, the lever area 57 of the lever 9 projects into the engagement area 48 of the Angled lever 59, wherein the valve 4/5 is activated, the angled lever 59 being rotatably mounted below the housing.

Die Figur 1 zeigt den erfindungsgemäßen Bausatz 1. Er besteht im wesentlichen aus einem Hebelgelenk 6, Steuernocken 7 und einem in Ein- und Ausgriffsstellung bringbaren Hebel 9.FIG. 1 shows the kit 1 according to the invention. It essentially consists of a lever joint 6, control cams 7 and a lever 9 which can be brought into the engagement and disengagement position.

Der Bausatz ist in einem Gehäuse 2 integriert. Der Arbeitsbalg 3, Luftströmkanal 25 sowie die Sperrventile 4 und 5 mit Rückstellfeder 60 bilden hierbei den an sich bekannten "Barker-Hebel". Bei Betätigung der Tastatur 11 (nicht dargestellt) wird der Hebel 9 durch den Anschlag 61 nach unten gezogen, wobei der Zug 8 diese Zugkraft zur Windlade überträgt und somit z. B. ein Schwanzventil (nicht dargestellt) zur Freigabe der Luft in die Pfeife (nicht dargestellt) betätigt.
Je nach dem, wieviel Pfeifen bzw. Register eingeschaltet sind, ist der auf die Tasten 11 aufzuwendende Druck sowie auch die Tastenrückstellkraft entsprechend hoch, so daß das Tastenspiel des Organisten beeinträchtigt wird. Durch den Einsatz des sogenannten "Barker-Hebels", wird dieser Nachteil wesentlich verbessert.
Jedoch muß die Feder 60 bei langen Abstrakten entsprechend stark ausgebildet sein, damit die Taste schnell genug zurückgeht und somit eine gute Repetition erreicht wird. Der Tastendruck am Spieltisch wird dann jedoch entsprechend dieser Federkraft größer, so daß das Spiel des Organisten negativ beeinflußt wird.The kit is integrated in a housing 2. The bellows 3, air flow channel 25 and the check valves 4 and 5 with return spring 60 form the "Barker lever" known per se. When the keyboard 11 (not shown) is actuated, the lever 9 is pulled downward by the stop 61, the train 8 transmitting this tensile force to the windchest and thus z. B. actuated a tail valve (not shown) to release the air into the pipe (not shown).
Depending on how many pipes or registers are switched on, the pressure to be exerted on the keys 11 and the key restoring force are correspondingly high, so that the organist's key play is impaired. This disadvantage is significantly improved by using the so-called "Barker lever".
However, in the case of long abstracts, the spring 60 must be of a correspondingly strong design so that the key returns quickly enough and thus a good repetition is achieved. However, pressing the button on the gaming table then increases in accordance with this spring force, so that the play of the organist is negatively influenced.

Um nun diese Kraft der Feder 60 nahezu zu eliminieren, ist erfindungsgemäß vorgesehen, daß auf dem Balg 3 ein das Hebelgelenk 6 aktivierbarer Stellstab 12 sowie ein an einem Lagerbock 13 befestigter Federhebel 16 angeordnet ist, der im Zusammenspiel mit einem unterhalb des Balgs 3 angeordneten Steuernockens 7 die Hubarbeit des Balgs zur Rückstellbewegung der Tastatur ausnützt.
Hierzu ist auf dem zum "Barker-Hebel" gehörenden Arbeitsbalg 3 ein Stellstab 12 vorgesehen, der mit dem Arbeitsbalg 3 die Hubbewegung beschreitet. Der Balg 3 selbst sitzt auf einem Luftströmkanal 25, wobei der Arbeitsbalg bei geöffnetem Ventil 4 und geschlossenem Ventil 5, aufgrund des geschlossenen Drucksystems aufgeblasen ist, wie in Figur 1 dargestellt.In order to almost eliminate this force of the spring 60, the invention provides that on the bellows 3 a Lever joint 6 activatable control rod 12 and a spring lever 16 fastened to a bearing block 13 are arranged, which, in interaction with a control cam 7 arranged below the bellows 3, uses the lifting work of the bellows to reset the keyboard.
For this purpose, an actuating rod 12 is provided on the working bellows 3 belonging to the "Barker lever", which moves with the working bellows 3 to the lifting movement. The bellows 3 itself sits on an air flow channel 25, the working bellows being inflated due to the closed pressure system when the valve 4 is open and the valve 5 is closed, as shown in FIG. 1.

Beim Ziehen des Ventils, d.h. durch Betätigen der Tasten 11 wird der Winkelhebel 59 um seine Achse 63 gedreht und zieht dabei, da dieser mittels Feststellschraube 64 am Zug 62 befestigt ist, das durch die Feder 60 belastete Ventil 5 in Freigabestellung und der Balg 3 fällt zusammen.When pulling the valve, i.e. by pressing the keys 11, the angle lever 59 is rotated about its axis 63 and pulls, since this is fastened to the train 62 by means of the locking screw 64, the valve 5 loaded by the spring 60 in the release position and the bellows 3 collapse.

Wird die Taste 11 losgelassen, so wird der Balg 3 wieder aufgeblasen. Nun kommt der erfindungsgemäße Bausatz 1 zum Einsatz. Beim Loslassen der Taste, also bei der Aufblasbewegung des Balgs 3 wird der Federhebel 16 mit nach oben genommen. Dies geschieht dadurch, da dieser am Lagerbock 13 mittels einer Drehachse 45 befestigt ist und der Lagerbock 13 selbst auf der Oberfläche 27 des Balgs 3 aufliegt. Hierbei greift der Einstellnocken 17 mit seinem Eingriffsbereich 49 unter die Nase 55 des Steuernockens 7 und zieht dabei die Abstrakten (nicht dargestellt) bzw. die Tasten mit zurück, so daß der Ton schnell abspricht und eine entsprechend gute Repetition gewährleistet wird. Kurz bevor der Balg 3 die oberste Position erreicht hat, wird der Steuernocken 7 und der Einstellnocken 17 voneinander getrennt, indem der Kipphebel 19, aktiviert über den Stellstab 12 gegen den Federhebel 16 drückt und somit den Einstellnocken 17 aus der Nase 55 des Steuernockens 7 zieht.
Dies ist wichtig, da sich beim erneuten Niederdrücken der Taste 11 der Steuernocken 7 frei bewegen muß.When the button 11 is released, the bellows 3 is inflated again. Now the kit 1 according to the invention is used. When the button is released, that is to say during the inflation movement of the bellows 3, the spring lever 16 is carried upward. This happens because it is attached to the bearing block 13 by means of an axis of rotation 45 and the bearing block 13 itself rests on the surface 27 of the bellows 3. Here, the setting cam 17 engages with its engagement area 49 under the nose 55 of the control cam 7 and thereby pulls the abstracts (not shown) or the buttons back, so that the tone speaks quickly and a correspondingly good repetition is ensured. Shortly before the bellows 3 has reached the top position the control cam 7 and the setting cam 17 are separated from one another by the rocker arm 19, activated via the setting rod 12, pressing against the spring lever 16 and thus pulling the setting cam 17 out of the nose 55 of the control cam 7.
This is important since the control cam 7 must move freely when the button 11 is depressed again.

Anhand den Figuren 1 bis 7 wird nun nochmals der gesamte Funktionsmechanismus des erfindungsgemäßen Bausatzes erläutert, wobei sich die Erläuterung auf das eingeschaltete System bezieht, wie in Figur 1 schematisch dargestellt ist.The entire functional mechanism of the kit according to the invention will now be explained again with reference to FIGS. 1 to 7, the explanation relating to the switched-on system, as shown schematically in FIG.

Durch Niederdrücken der Taste 11 wird der Hebel 9 niedergedrückt bzw. um den Achspunkt 65 gedreht. Hierzu ist die Tastatur 11 mittels eines Zuges 66 mit dem Hebel 9 verbunden, wobei eine Anschlagschraube 61 unmittelbar auf dem Hebel 9 anliegt und diesen mit nach unten, entsprechend der Zugbewegung mitführt.
Hierbei greift das Hebelteil 57 des Hebels 9 in den Bereich 58 des Winkelhebels 59, der um eine Achse 63 eines Lagerbocks 68 unterhalb des Gehäuses 2 drehbar gelagert ist. Der abgewinkelte Bereich 69 des Winkelhebels 59 ist mittels eines Zuges 62 mit dem Ventil 5 und 4 verbunden sowie mittels der Stellschraube 64 arretiert. Durch die Einwirkung des Hebels 9 auf den Winkelhebel 59 wird das Ventil 5 in Freigabestellung gebracht, wobei die Kraft der Feder 60, die durch den Anschlag 70 gekontert ist, zu überwinden ist.Depressing the button 11 depresses the lever 9 or rotates it about the axis point 65. For this purpose, the keyboard 11 is connected to the lever 9 by means of a train 66, a stop screw 61 being in direct contact with the lever 9 and carrying it downward in accordance with the train movement.
Here, the lever part 57 of the lever 9 engages in the area 58 of the angle lever 59, which is rotatably mounted about an axis 63 of a bearing block 68 below the housing 2. The angled region 69 of the angle lever 59 is connected to the valve 5 and 4 by means of a train 62 and locked by means of the adjusting screw 64. The action of the lever 9 on the angle lever 59 brings the valve 5 into the release position, the force of the spring 60, which is countered by the stop 70, to be overcome.

Durch das Setzen des Ventils 5 in Freigabestellung, wobei das Ventil 4 in Sperrstellung gebracht wird, fällt der Balg 3 zusammen, womit auch keine Kraft mehr über den Stellstab 12 auf den Winkelhebel 19 einwirkt. Bei dem Zusammenfallen des Balgs 3 wird der Steuernocken 7 aktiviert. Dieser ist unterhalb des Balgs 3, vorzugsweise mittels eines Lagerbocks 71 um eine Achse 51 drehbar angeordnet, wobei der Zug 62 der mit dem Ventil 4 und 5 verfährt, in einen Achspunkt 53 des Nockens 7 geführt ist und diesen somit um die Achse 51 dreht. Der Achspunkt 53 beschreitet hier eine Kreisbahn 54 um den Achspunkt 51, wobei das Ventil 4 und der Zug 62, wie in Figur 5 schematisch dargestellt ist, eine geringe Aufwärtsbewegung vollzieht. Dies kann jedoch aufgrund der Dichtelemente an den Ventilen unberücksichtigt bleiben.By setting the valve 5 in the release position, whereby the valve 4 is brought into the blocking position, the bellows 3 collapses, so that no more force acts on the angle lever 19 via the actuating rod 12. When the bellows 3 collapses, the control cam 7 is activated. This is arranged below the bellows 3, preferably rotatable about an axis 51 by means of a bearing block 71, the train 62 which travels with the valve 4 and 5 being guided into an axis point 53 of the cam 7 and thus rotating it about the axis 51. The axis point 53 here follows a circular path 54 around the axis point 51, the valve 4 and the train 62, as shown schematically in FIG. 5, making a slight upward movement. However, this can be ignored due to the sealing elements on the valves.

Die Nase 55 des Steuernockens 7 kann hierbei frei verfahren, da der Einstellnocken 17 zu diesem Zeitpunkt außer Eingriff mit dem Steuernocken 7 steht, wie später noch beschrieben wird. Die Abwärtshubbewegung des Balgs 3 bleibt insofern auf den Winkelhebel 19 ohne Einwirkung, da dieser über den Lagerbock 29 an der Achse 30 auf der Balghubbegrenzung 18 aufliegt, die nicht mit dem Balg 3 verbunden ist, d.h. nicht mit der Hubbewegung des Balgs 3 in Verbindung steht.The nose 55 of the control cam 7 can move freely here, since the setting cam 17 is out of engagement with the control cam 7 at this time, as will be described later. The downward stroke movement of the bellows 3 has no effect on the angle lever 19, since this rests on the axle 30 on the bellows stroke limitation 18, which is not connected to the bellows 3, i.e. via the bearing block 29. is not connected to the lifting movement of the bellows 3.

Lediglich der Stellstab 12 wirkt nicht mehr auf den Winkelhebel 19. Da die Abwärtsbewegung des Balgs 3 träger ist als die Ventilbewegung, wird somit auch der Einstellnocken 17 erst nachdem das Ventil 4 geschlossen hat und der Steuernocken 7 verdreht ist, nachgeführt, so daß, wie in Figur 5 dargestellt, dieser bei der untersten Stellung des Balgs 3 mit seinem Eingriffsbereich 49 unter die Nase 55 des Steuernockens 7 geführt wird.Only the control rod 12 no longer acts on the angle lever 19. Since the downward movement of the bellows 3 is slower than the valve movement, the adjusting cam 17 is therefore only adjusted after the valve 4 has closed and the control cam 7 is rotated, so that how shown in Figure 5, this is guided with its engagement area 49 under the nose 55 of the control cam 7 in the lowest position of the bellows 3.

Wenn nun die Taste wieder losgelassen wird, wird der Balg 3 aufgeblasen. Dabei wird der Federhebel 16 nach oben mitgenommen und zieht die Abstrakten (nicht dargestellt) bzw. die Tasten 11 mit zurück, wobei der Einstellnocken 17 in Eingriff unter die Nase 55 des Steuernockens 7 verbleibt. Kurz bevor der Balg 3 die oberste Position erreicht hat, wird durch die Aktivierung des Winkelhebels 19 der nun mit seinem Anschlagkopf 20 eine Kreisbahn 72 um die Achse 30 beschreitet der Federhebel 16 gegen den Federträger 14 bewegt, wobei der Einstellnocken 17 die Kreisbahn 73 um die Achse 45 beschreitet und außer Eingriff mit der Nase 55 des Nockens 7 kommt.When the button is released again, the bellows 3 is inflated. The spring lever 16 is carried upwards and pulls the abstracts (not shown) or the keys 11 back, the adjusting cam 17 remaining in engagement under the nose 55 of the control cam 7. Shortly before the bellows 3 has reached the uppermost position, the spring lever 16 is moved against the spring carrier 14 by activating the angle lever 19, which now moves with its stop head 20 with a circular path 72 around the axis 30, the adjusting cam 17 moving the circular path 73 around the Axis 45 treads and comes out of engagement with the nose 55 of the cam 7.

Die Anordnung zum Ein- und Ausschalten der erfindungsgemäßen Rückstellhilfe wird nun anhand der Figur 1 näher beschrieben.The arrangement for switching the reset aid according to the invention on and off is now described in more detail with reference to FIG. 1.

Hierzu ist der Hebel 9 an einer Aufnahmeleiste 56 drehbar in der Achse 65 gelagert. Die Leiste 56 nimmt hierbei eine Vielzahl von Hebeln 9, entsprechend der Tastenanzahl auf. Die Aufnahmeleiste 56 erfordert hierbei keine Verbindung mit dem Gehäuse 2 und ist als Ganzes höhenverfahrbar ausgebildet, d.h. die Aufnahmeleiste 56 ist z. B. stirnseitig gelagert und über einen Hebel oder Schwenkmechanismus in der Höhe verfahrbar, so daß der Hebel 9 um den theoretischen Punkt 74 geschwenkt wird und hierbei eine Kreisbahn 75 beschreitet, so daß ein Abstand zwischen Hebelteil 57 und Hebelteil 58 des Hebels 59 entsteht, der keinen Eingriff mehr des Hebels 9 in den Hebel 59 erlaubt und hierbei der Hebel 9 auf dem Anschlag 76 aufliegt, der praktisch das Ende des Zuges 8 bildet. Nun wird bei Tastendruck und somit das Bewegen des Hebels 9, der Hebel 10 über die Anschläge 76 und 77 aktiviert, wobei der Hebel 10 unterhalb des Gehäuses 2 in einer Achse 78 drehbar angeordnet ist.For this purpose, the lever 9 is rotatably mounted on a receiving bar 56 in the axis 65. The bar 56 accommodates a plurality of levers 9, corresponding to the number of buttons. The receiving bar 56 does not require a connection to the housing 2 and is designed to be vertically movable as a whole, ie the receiving bar 56 is, for. B. frontally mounted and movable in height by means of a lever or swivel mechanism, so that the lever 9 is pivoted about the theoretical point 74 and in this case follows a circular path 75, so that a distance between the lever part 57 and lever part 58 of the lever 59 arises, the no more engagement of the lever 9 in the lever 59 is permitted and the lever 9 rests on the stop 76, which practically forms the end of the train 8. Now at the push of a button and thus moving the lever 9, the lever 10 is activated via the stops 76 and 77, the lever 10 being rotatably arranged below the housing 2 in an axis 78.

Jedem Manual, bei dem ein Barker-System gewünscht wird, ist für jede Taste bzw. jeden Ton der erfindungsgemäße Bausatz zuzuordnen, d.h. z. B. bei einem Manual mit 58 Tasten Tonumfang, z. B. C bis a′′′ werden 58 Bausätze in mehreren Ebenen übereinander jeweils um eine Manualteilung bzw. Tastenteilung versetzt angeordnet.The kit according to the invention is to be assigned to each manual for which a Barker system is desired, i.e. e.g. B. in a manual with 58 keys, e.g. B. C to a '' '58 kits are arranged in several levels one above the other, each offset by a manual division or key division.
