Description

Die Erfindung betrifft eine Vorrichtung zum Wenden von Blättern von auf einem Ständer stehendem Schriftgut, insbesondere Notenblättern, mit einem das zu wendende Blatt an seiner Oberkante umgreifenden Wendeorgan, das von einem horizontalen Arm nach unten absteht, welcher von einer um eine vertikale Achse verdrehbaren Stange gehalten ist, die über ein Getriebe mit einem Fußbetätigungsorgan verbunden ist.The invention relates to a device for turning sheets of documents standing on a stand, in particular sheet music, with a turning member encompassing the sheet to be turned on its upper edge, which projects downward from a horizontal arm, which is held by a rod rotatable about a vertical axis is connected to a foot actuator via a transmission.

Eine derartige Vorrichtung ist in der US-A 1 720 827 beschrieben und dargestellt. Diese bekannte Wendevorrichtung ist in einen Notenständer eingebaut, der somit in entsprechender Weise konstruiert, hergestellt und vertrieben werden muß. Der Einsatz der Wendevorrichtung bei einem handelsüblichen Notenständer ist nicht möglich. Die bekannte Wendevorrichtung ist dabei so aufgebaut, daß das Getriebe mit dem Fußbetätigungsorgan am unteren, rohrförmigen Ende des Ständers angebaut ist, der über ein Dreibein am Boden abgestützt ist. Das Fußbetätigungsorgan besteht aus einem Drehknopf mit zwei verhältnismäßig kurzen Armen, was die Fußbetätigung erschwert. Durch die erläuterte Konstruktion ist die Standsicherheit stark eingeschränkt.Such a device is described and shown in US-A 1 720 827. This known turning device is installed in a music stand, which must therefore be designed, manufactured and sold in a corresponding manner. It is not possible to use the turning device on a standard music stand. The known turning device is constructed so that the gear with the foot actuator is attached to the lower, tubular end of the stand, which is supported on the ground by a tripod. The foot control consists of a knob with two relatively short arms, which makes foot control difficult. The stability described is severely restricted by the construction explained.

Aus der US-A 1 716 693 ist ein Blattwender bekannt, der nur für den Anbau an ein Klavier vorgesehen ist, wobei auch hier erhebliche bauliche Änderungen vorgesehen werden müssen, um den Seilzug vom Notenpult zum Pedal zu führen.A sheet turner is known from US-A 1 716 693, which is only intended for attachment to a piano, with considerable structural changes also having to be made here in order to guide the cable from the music stand to the pedal.

Bei der aus der DE-A 293 329 bekannten Vorrichtung wird das zu wendende Blatt nicht an seiner Oberkante umgriffen, sondern wird von einem seitlich hochkant stehenden Organ mit zwei Klammern erfaßt. Zwar kann diese bekannte Wendevorrichtung an einem handelsüblichen Notenständer mittels Klammern befestigt werden, aber dadurch verringert sich die Standsicherheit der gesamten Vorrichtung erheblich, insbesondere beim Betätigen eines der beiden Pedale.In the device known from DE-A 293 329, the sheet to be turned is not gripped at its upper edge, but is grasped by an organ standing on its side with two clamps. Although this known turning device can be fastened to a commercially available music stand by means of clips, this considerably reduces the stability of the entire device, in particular when one of the two pedals is actuated.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs angegebenen Gattung so auszubilden, daß sie bei bestehenden Notenständern oder dgl. eingesetzt werden kann, ohne daß an diesen konstruktive Änderungen vorgenommen werden müssen.The invention has for its object to design a device of the type mentioned in such a way that it can be used in existing music stands or the like. Without having to make any structural changes to them.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Getriebe in einem kastenförmigen Gehäuse mit Füßen untergebracht ist, von dem ein Bolzen zum Befestigen des Ständers nach oben absteht.This object is achieved in that the transmission is housed in a box-shaped housing with feet, from which a bolt for fastening the stand protrudes upwards.

Diese Lösung hat gegenüber dem Stand der Technik den wesentlichen Vorteil, daß handelsübliche Notenständer verwendet werden können, die lediglich auf den Bolzen des Gehäuses aufgesteckt und dort festgeklemmt werden. Eine konstruktive Änderung der Notenständer ist nicht erforderlich.This solution has the essential advantage over the prior art that commercially available music stands can be used, which are simply plugged onto the bolts of the housing and clamped there. A constructive change of the music stand is not necessary.

In Weiterbildung der Erfindung ist vorgesehen, daß das Getriebe eine horizontale Welle hat, an deren aus dem Gehäuse vorstehendem Ende das als zweiarmiger Hebel ausgebildete Fußbetätigungsorgan abnehmbar befestigt ist. Ferner kann das Getriebe eine vertikale Welle haben, an deren aus dem Gehäuse vorstehendem Ende die Stange lösbar befestigt ist. Mit diesen Maßnahmen sind ein rasches Zerlegen und Zusammenbauen möglich, ohne daß hierfür Werkzeuge erforderlich sind.In a further development of the invention, it is provided that the gear has a horizontal shaft, on the end of which protrudes from the housing, the foot actuating member, which is designed as a two-armed lever, is removably attached. Furthermore, the transmission can have a vertical shaft, on the end of which protrudes from the housing, the rod is releasably attached. With these Measures can be quickly dismantled and reassembled without the need for tools.

Nach einem weiteren Merkmal der Erfindung ist der horizontale Arm lösbar und mittels eines Schiebelagers verstellbar am oberen Ende der Stange befestigt und trägt an seinen beiden Enden je ein Wendeorgan.According to a further feature of the invention, the horizontal arm is detachably and adjustably fastened to the upper end of the rod by means of a sliding bearing and carries a turning member at both ends.

Zum Wenden der Blätter auf einem Notenpult oder dgl. genügt es, das Wendeorgan auf die zu wendende Seite oder die darauf folgende Seite aufzustecken, um bei Bedarf über das Fußbeätigungsorgan den Arm um etwa 180° zu schwenken; wenn das Wendeorgan auf die übernächste Seite aufgesteckt worden ist, kann nach dem ersten Wenden der Arm rasch zurückgedreht werden, wobei die zuviel gewendeete Seite zurückgedreht wird, so daß sie beim nächsten Umblättern ebenfalls mechanisch gewendet werden kann.To turn the sheets on a music stand or the like. It is sufficient to attach the turning organ to the side to be turned or the following side, in order to swivel the arm about 180 ° if necessary via the foot actuation organ; if the turning element has been plugged onto the next but one page, the arm can be quickly turned back after the first turning, the overturned side being turned back so that it can also be turned mechanically the next time the page is turned.

Bei der in den Figuren 1 bis 4 dargestellten Vorrichtung ist ein kastenförmiges Gehäuse 10 mit drei Füßen 12 zu erkennen. In eine Bohrung in der Oberseite 14 des Gehäuses 12 ist der vertikale Fuß 16 eines Notenständers 18 eingesteckt, auf dem das Schriftgut 20 im wesentlichen stehend angeordnet ist. Der Fuß 16 des Notenständers 18 ist im Gehäuse 10 über eine Feststellschraube 22 festgeklemmt.In the device shown in Figures 1 to 4, a box-shaped housing 10 with three feet 12 can be seen. In a hole in the top 14 of the housing 12, the vertical foot 16 of a music stand 18 is inserted, on which the document 20 is arranged essentially standing. The foot 16 of the Music stand 18 is clamped in the housing 10 via a locking screw 22.

Zum Wenden der Blätter 24 des Schriftgutes 20 dient ein U-förmiger, nach unten offener Bügel 26, dessen vertikale Klemmplatten 28 das Blatt 24 an seiner Oberkante umgreifen. Wie Figur 2 zeigt, ist der Bügel 26 über eine Mutter 30 an einem Bolzen 32 befestigt, der frei drehbar in eine Bohrung 34 eines horizontalen Armes 36 eingesetzt ist. Der Arm 36 hat mehrere derartiger Bohrungen 34, so daß die Position des Bügels 26 am Arm 36 an die Abmessung des Schriftgutes 20 angepaßt werden kann.A U-shaped, downwardly open bracket 26 is used to turn the sheets 24 of the writing material 20, the vertical clamping plates 28 of which grip around the sheet 24 on its upper edge. As FIG. 2 shows, the bracket 26 is fastened via a nut 30 to a bolt 32 which is inserted into a bore 34 in a horizontal arm 36 in a freely rotatable manner. The arm 36 has several such bores 34, so that the position of the bracket 26 on the arm 36 can be adapted to the size of the writing material 20.

Der Arm 36 ist mit einer Stange 38 verbunden, die in vertikaler Stellung hinter dem Fuß 16 des Notenständers 18 angeordnet ist. Das untere Ende der Stange 38 ist über eine Klemmschraube 40 mit einer vertikalen Welle 42 verbunden, die über die Oberseite 14 des Gehäuses 10 hervorsteht.The arm 36 is connected to a rod 38 which is arranged in the vertical position behind the foot 16 of the music stand 18. The lower end of the rod 38 is connected via a clamping screw 40 to a vertical shaft 42 which protrudes above the top 14 of the housing 10.

Die Welle 42 trägt im Gehäuse 10 ein Abtriebszahnrad 44 eines Kegelradgetriebes 46, dessen Antriebszahnrad 48 eine horizontale Welle 50 hat. Die horizontale Welle 50 ragt über die vordere Stirnseite 52 des Gehäuses 10 hervor und trägt ein Fußbetätigungsorgan 54. Dieses ist als eine Platte ausgebildet, die an der Welle 50 befestigt ist und mit dieser um deren horizontale Achse verschwenkt werden kann.The shaft 42 carries in the housing 10 an output gear 44 of a bevel gear 46, the drive gear 48 has a horizontal shaft 50. The horizontal shaft 50 protrudes over the front end face 52 of the housing 10 and carries a foot actuating member 54. This is designed as a plate which is fastened to the shaft 50 and can be pivoted with the latter about its horizontal axis.

Um mit dieser Vorrichtung das zwischen die Klemmplatten 28 des Bügels 26 eingelegte Blatt 24 zu wenden, wird die Platte des Fußbetätigungsorgans 54 auf einer Seite mit dem Fuß niedergedrückt, etwa in Richtung des Pfeiles P in Figur 1, wodurch über das Kegelradgetriebe 46 die Stange 38 um etwa 150° in Richtung des Pfeiles S gedreht wird. Damit dreht sich auch der Arm 36 und nimmt über den Bügel 26 das Blatt 24 mit, bis es auf der gegenüberliegenden Seite zu liegen kommt. In umgekehrter Richtung kann das Blatt 24 wieder zurückgeschwenkt werden.In order to use this device to turn the sheet 24 inserted between the clamping plates 28 of the bracket 26, the plate of the foot actuating member 54 is pressed down on one side with the foot, approximately in the direction of the arrow P in FIG is rotated by approximately 150 ° in the direction of arrow S. This also rotates the arm 36 and takes the sheet 24 with it via the bracket 26 until it comes to rest on the opposite side. In the opposite direction, the sheet 24 can be pivoted back again.

Bei der in Figur 4 gezeigten Variante ist die vertikale Stange 38 teleskopisch verstellbar ausgebildet und hat hierzu einen im Durchmesser dünneren Stangenteil 38', der mittels einer Klemmschraube 56 feststellbar im unteren Teil der Stange 38 sitzt. In entsprechender Weise ist auch der Arm 36 horizontal teleskopisch verstellbar und sitzt über eine Klemmschraube 58 feststellbar auf einem dünneren Armabschnitt 36', der einstückig mit dem Stangenteil 38' ausgebildet ist.In the variant shown in FIG. 4, the vertical rod 38 is designed to be telescopically adjustable and, for this purpose, has a rod part 38 ′ which is thinner in diameter and which is seated in the lower part of the rod 38 by means of a clamping screw 56. In a corresponding manner, the arm 36 is also telescopically adjustable horizontally and can be locked by means of a clamping screw 58 on a thinner arm section 36 'which is formed in one piece with the rod part 38'.

Die Klemmplatten 28 des Bügels 26 sind sehr dicht nebeneinander angeordnet und umgreifen das nicht gezeigte, zu wendende Blatt sehr eng, vorzugsweise mit geringem Federdruck, damit es beim Wenden nicht an einem Vorsprung 60 des Notenständers 18 hängenbleibt und aus dem Bügel 26 herausrutscht.The clamping plates 28 of the strap 26 are arranged very close to each other and grip the sheet not shown, to be turned very tightly, preferably with little spring pressure, so that it does not get stuck on a projection 60 of the music stand 18 and slip out of the strap 26 when turned.

In Figur 4 ist gezeigt, wie der hohle Fuß 16 des handelsüblichen Notenständers 18, dessen hochgeklapptes Dreibein 62 angedeutet ist, auf einen mittels der Feststellschraube 22 im Gehäuse 10 befestigten Stift 64 aufgesetzt und auf diesem über eine Klemmschraube 66 fixiert wird.FIG. 4 shows how the hollow foot 16 of the commercially available music stand 18, the raised tripod 62 of which is indicated, is placed on a pin 64 fastened in the housing 10 by means of the locking screw 22 and fixed thereon by means of a clamping screw 66.

Die Figuren 5 bis 7 zeigen eine besonders vorteilhafte Ausführungsform, bei der die beiden vorderen Füße 12' des Gehäuses 10 um vertikale Achsen 68 schwenkbar an diesem befestigt sind. Außerdem besteht das Fußbetätigungsorgan 54 aus einem zweiarmigen Hebel 70, der mittig über eine Feststellschraube 72 lösbar an der Welle 50 angebracht ist. Mit diesen Maßnahmen läßt sich die Vorrichtung rasch zerlegen, um sie in einen Koffer oder dgl. zu verpacken.FIGS. 5 to 7 show a particularly advantageous embodiment in which the two front feet 12 'of the housing 10 are fastened to the housing 10 such that they can pivot about vertical axes 68. In addition, the foot actuator 54 consists of a two-armed lever 70, which is releasably attached to the shaft 50 via a locking screw 72. With these measures, the device can be quickly disassembled to be packed in a suitcase or the like.

Weiter ist zu erkennen, daß der oberste Stangenteil 38'' ein Klemmorgan 74 mit einer Klemmschraube 76 trägt, über die ein Schiebelager 78 am Klemmorgan 74 befestigt ist. Zum Zusammenlegen der Vorrichtung kann das Schiebelager 78 um die Achse der Klemmschraube 76 in Pfeilrichtung nach unten geschwenkt werden. In einer horizontalen Bohrung des Schiebelagers 78 sitzt verstellbar der als Stange ausgebildete Arm 36'', der in seinem mittleren Bereich durch eine Feststellschraube 80 im Schiebelager 78 fixiert werden kann. Der Arm 36'' trägt an seinen beiden Enden je ein Wendeorgan, das aus zwei Klemmplatten 28 besteht, die mittels einer Klemmschraube 82 in einem Bügel 84 festgelegt sind, der an dem zugehörigen Ende des Arms 36'' nach unten absteht.It can also be seen that the uppermost rod part 38 ″ carries a clamping member 74 with a clamping screw 76, via which a sliding bearing 78 is fastened to the clamping member 74.
