PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf Pedale, im besonderen solche zum Antreiben von Blasebälgen für selbstspielende Klaviere, für Spielvorrichtungen für Klaviere, Orgeln u. dgl. und bezweckt, die. Pedale in einfacher Weise außer Gebrauch derart unterzubringen, daß sie nur wenig Raum beanspruchen.The invention relates to pedals, particularly those for driving bellows for self-playing pianos, for playing devices for pianos, organs and the like. and aims that. To accommodate pedals in a simple manner out of use in such a way that they take up little space.

Zu diesem Zweck sind die Pedale innerhalb eines beweglichen Rahmens angeordnet,For this purpose, the pedals are arranged within a movable frame,

ίο der mit Führungsstücken versehen ist, wobei ein oder mehrere Pedale an dem Rahmen angelenkt sind. Jedes Pedal ist durch einen Gelenkhebel unmittelbar mit dem beweglichen Teil des Balges o. dgl., zu dessen Bedienung es bestimmt ist, drehbar verbunden, während die Führungsstücke des Rahmens in Führungen laufen, an denen sich der Rahmen mit den Pedalen entlang bewegt, wenn die letzteren auf- oder zusammengeklappt werden sollen.ίο which is provided with guide pieces, whereby one or more pedals are hinged to the frame. Each pedal is through one Articulated lever directly with the moving part of the bellows o. The like. To operate it it is intended to be rotatably connected, while the guide pieces of the frame in guides run along which the frame moves along with the pedals, if the latter should be opened or collapsed.

Durch diese Bauart sind die Pedale möglichst leicht, können schnell und bequem von der einen in die andere Lage gebracht werden, während sie in den Endlagen selbst so gesichert sind, daß die einzelnen Teile keine Nebengeräusche hervorbringen, und können in zusammengeklapptem Zustand unsichtbar innerhalb des Klaviergehäuses untergebracht werden.Thanks to this design, the pedals are as light as possible and can be quickly and easily accessed from the one in the other position, while they are secured in the end positions themselves are that the individual parts do not produce any background noise, and can When folded, it is invisibly housed inside the piano case will.

Der Erfindungsgegenstand ist auf der Zeichnung dargestellt:The subject of the invention is shown in the drawing:

Fig. ι ist ein mittlerer Längsschnitt durch den unteren Teil eines selbstspielenden Klaviers mit den Pedalen in Gebrauchslage, die punktierten Linien deuten ihre Stellung nach dem Niedertreten an;Fig. Ι is a central longitudinal section through the lower part of a self-playing piano with the pedals in the position of use, the dotted lines indicate their position the trampling on;

Fig. 2 ist ein Längsschnitt in größerem Maßstabe, aus dem die Stellung der Pedale in zusammengeklappter Lage ersichtlich ist; Fig. 3 ist eine Ansicht von vorn,Fig. 2 is a longitudinal section, on a larger scale, showing the position of the pedals can be seen in the folded position; Fig. 3 is a front view,

Fig. 4 ein Grundriß.Fig. 4 is a plan view.

Fig. 3 und 4 sind im Maßstabe der Fig. 1 gezeichnet.FIGS. 3 and 4 are to the scale of FIG. 1 drawn.

ι ist die feststehende Wand der Hauptbälge, welche mit einer gleichfalls feststehenden Windlade 2 verbunden sind; die letztere steht durch ein Rohr 3 mit der nicht dargestellten pneumatischen Vorrichtung im oberen Teil des Klaviergehäuses in Verbindung. Die pneumatische Vorrichtung dient zur Bewegung der Klaviermechanik, wenn das Instrument in mechanischer Weise gespielt werden soll. An dem freien Ende der beweglichen Wand 5 der Bälge ist bei 6 ein Gelenkhebel 7 angebracht, dessen anderes Ende bei 8 mit dem vorderen Ende des Pedals 9 drehbar verbunden ist. Die Pedale sind bei 10 angelenkt, und zwar an einer Querstange 11, die zusammen mit den festen Teilen 12 den Pedalrahmen bilden. Dieser Rahmen besitzt geeignete Führungsstücke 13, die in Schlitzen 14 der Führungen 15, welche innerhalb des Klaviergehäuses 4 mit diesem verbunden sind, laufen. Zweckmäßig bestehen die Führungsstücke aus angebogenen oder aufgesetzten Zapfen 13 an den Stangen 12. In der Zeichnung sind die Führungen oben an der Windlade 2 und unten an der vorderen Bodenschiene des Gehäuses angebracht. Die Schlitze 14 sind bei 17 wagerecht nach außen gebogen, zum Zweck, die Zapfen 13ι is the fixed wall of the main bellows, which is also fixed with a Wind chest 2 are connected; the latter stands by a pipe 3 with the one not shown pneumatic device in the upper part of the piano case. The pneumatic device is used to move the piano action when the instrument is played in a mechanical manner shall be. At the free end of the movable wall 5 of the bellows, an articulated lever 7 is attached at 6, the other of which End at 8 with the front end of the pedal 9 is rotatably connected. The pedals are hinged at 10, on a crossbar 11, which together with the fixed Parts 12 form the pedal frame. This frame has suitable guide pieces 13, those in slots 14 of the guides 15, which within the piano housing 4 with this connected, run. The guide pieces expediently consist of bent or attached pins 13 on the rods 12. In the drawing, the guides are at the top of the wind chest 2 and at the bottom of the front one Mounted on the bottom rail of the housing. The slots 14 are horizontal at 17 bent outwards, for the purpose of removing the tenons 13

Claims

to prevent sliding up in the slots 14 in the position of use. When the pedals are folded up in the piano housing 4, the rod 11 automatically snaps into a resilient hook 18 which is attached to a block 19, while the front ends of the pedals 9 come to lie under a locking hook 20, which is for example on the wind chest 2 is attached. In order to bring the pedals from the folded position into the position of use, the frame 11 is grasped with one hand and pulled off the spring 18. Then the rod and the pedals connected to it are pulled downwards and outwards, the pins 13 being guided in the slots 14 until they reach the bends 17. The pedal frame rests on feet 21 on the rod 11 on the floor. In the position of use (FIGS. 1, 3 and 4), the pedals 9 are securely held and act on the bellows by means of the articulated lever 7 in a noiseless manner. Their upward movement from the lowest position shown in dotted lines takes place in the usual way by the springs of the bellows. In order to bring the pedals into the piano case, the frame rod 11 is guided upwards and inwards by hand, with the pegs 13 again moving in the slots 17, 14 until the rod II automatically snaps into the hook 18 and the pedals 9 lie down behind the hooks 20. The two hooks mentioned hold the pedals firmly in this position and secure them against noisy movements even when the piano is lively by hand or during transport. While the pedals can be quickly and easily brought into the position of use and folded up from there with one hand, a hinged board on the front side of the piano case is opened with the other hand in order to bring the frame into or out of the case to be able to. The drawing shows an expedient arrangement of said board, which consists of two parts, of which the larger upper 22 is connected to the housing 4 at 23, while the smaller lower 24 is connected to the upper part 22 at 25 that it opens inwards. A button 26 is attached to the part 24. When the pedals are inside the piano housing 4, the two-part door 22, 24 is closed so that the pedals are not visible from the outside (FIG. 2). When the pedals are to be brought into the position of use, the door 22, 24 is first swung upwards, as indicated by dotted lines in FIG. 1, and then the lower part 24 is swung inwards and upwards so that it is flat on the inside of the board is applied (Fig. 1). This frees an opening for the lever 7. With this arrangement of the pedals they do not come or with the usual pedals 27 for damping. Enhance the tone in touch. Many modifications of the described arrangements are possible without departing from the essence of the invention. So it is z. B. not essential that the rods 12 are rigidly connected to the rod 11. It is only important that these rods are in sliding connection with fixed guides of an expedient construction, such that the pedal frame is guided with the pedals when it is opened or collapsed. It is also not absolutely necessary for the pedals to be folded up inside the housing of the instrument; this can also be done outside the housing, although the arrangement described is the more expedient.
