Description

Die Erfindung betrifft eine Vorrichtung zum Wenden von Blättern von auf einem Ständer stehendem Schriftgut, insbesondere Noten­blättern, mit einem das zu wendende Blatt erfassenden Wendeor­gan, das über ein Gestänge 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 element which detects the sheet to be turned and which is connected to a foot actuating element via a linkage.

Aus der DE-PS 333 986 ist ein Notenblattwender bekannt, der Teil eines Notenständers ist. Das Fußbetätigungsorgan ist über ein zahlreiche Gelenke und Hebel aufweisendes Gestänge an der Rückseite einer Tragplatte für das Schriftgut mit einem Schubhe­bel verbunden, dessen freies Ende eine Gummiauflage hat, welche das zu wendende Blatt aufwölbt; sodann greift ein in einer Ku­lissenführung verschiebbarer Finger unter das aufgewölbte Blatt und wendet dieses.From DE-PS 333 986 a sheet turner is known, which is part of a music stand. The foot actuator is connected via a linkage with numerous joints and levers on the back of a support plate for the documents with a push lever, the free end of which has a rubber pad which bulges the sheet to be turned; then a finger that can be moved in a slide guide reaches under the arched leaf and turns it.

Gegenstand des deutschen Gebrauchsmusters 87 15 581 ist eine Vorrichtung zum Umblättern der Seiten einer Partitur, deren zu wendende Seite jeweils zunächst von einem Haftkissen angehoben werden muß, damit anschließend ein Wendestab unter dieses Blatt greifen und es umlegen kann. Der Antrieb der Vorrichtung er­folgt durch einen Elektromotor, der über einen Fußschalter betä­tigt wird.The subject of German utility model 87 15 581 is a device for turning the pages of a score, the page to be turned must first be lifted by an adhesive cushion so that a turning stick can then reach under this sheet and flip it over. The device is driven by an electric motor, which is operated via a foot switch.

Aus der DE-PS 21 24 540 ist schließlich ein Blattwender be­kannt, der an einem Notenständer angebracht werden kann. Zum Um­legen der einzelnen Seiten ist ein schwenkbarer Wendearm vorge­sehen, dessen freies Ende eine Dauermagneten zum Halten der Blattränder aufweist, die mit magnetischen Teilen versehen wer­den müssen. Auch hier erfolgt der Antrieb über einen Elektromo­tor.From DE-PS 21 24 540 a sheet turner is finally known, which can be attached to a music stand. A swiveling turning arm is provided for folding over the individual pages, the free end of which has a permanent magnet for holding the sheet edges, which must be provided with magnetic parts. Here, too, it is driven by an electric motor.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Wenden von Blättern von Schriftgut zur Verfügung zu stellen, die wesentlich einfacher aufgebaut ist und bei bestehenden No­tenständern o. dgl eingesetzt werden kann, um einzelne Seiten umzublättern.The invention has for its object to provide a device for turning pages of documents, which is much simpler and can be used in existing music stands or the like to turn individual pages.

Bei der Vorrichtung der eingangs umrissenen Gattung wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das Wendeorgan aus zwei Klemmplatten besteht, die das zu wendende Blatt an seiner Oberkante umgreifen und von einem horizontalen Arm nach unten abstehen, welcher um eine vertikale Achse schwenkbar über dem Schriftgut angeordnet und Teil des mit dem Fußbetätigungsorgan verbundenen Gestänges ist.In the device of the type outlined at the outset, this object is achieved according to the invention in that the turning element consists of two clamping plates which grip around the sheet to be turned at its upper edge and protrude downward from a horizontal arm which is pivotably arranged about a vertical axis above the documents and is part of the linkage associated with the foot actuator.

Diese Lösung erfordert gegenüber dem Stand der Technik einen we­sentlich geringeren Aufwand für die Konstruktion und die Monta­ge und erfüllt trotzdem in zufriedenstellender Weise seinen Zweck, wenn nur wenige Blätter gewendet werden sollen. Hierzu genügt es, die beiden Klemmplatten auf die zu wendende Seite oder die darauf folgende Seite aufzustecken, um bei Bedarf über das Fußbetätigungsorgan den Arm um etwa 180o zu schwenken; wenn die Klemmplatten auf die übernächste Seite aufgesteckt worden sind, kann nach dem ersten Wenden der Arm rasch zurückgedreht werden, wobei die zuviel gewendete Seite zurückgedreht wird, so daß sie beim nächsten Umblättern ebenfalls mechanisch gewendet werden kann.Compared to the prior art, this solution requires considerably less effort for the construction and assembly and nevertheless satisfactorily fulfills its purpose if only a few sheets are to be turned. For this purpose, it is sufficient aufzustecken the two clamping plates on the side to be turned or the subsequent side to pivot the arm by about 180 ° on demand from the Fußbetätigungsorgan; if the clamping plates have been pushed onto the next but one page, the arm can be quickly turned back after the first turning, whereby the overturned side is turned back so that it can also be turned mechanically the next time the page is turned.

Der Arm, von dem die Klemmplatten abstehen, ist mit einer um die vertikale Achse verdrehbaren Stange verbunden, die über ein Getriebe mit dem Fußbetätigungsorgan verbunden ist.The arm from which the clamping plates protrude is connected to a rod which can be rotated about the vertical axis and which is connected to the foot actuating member via a gear.

Das Getriebe ist vorzugsweise ein in einem Gehäuse gelagertes Kegelradgetriebe, von dem das Abtriebszahnrad eine vertikale Welle hat, an der die Stange befestigt ist, während das An­triebszahnrad eine horizontale Welle hat, die aus dem Gehäuse herausragt und das Fußbetätigungsorgan trägt.The gearbox is preferably a bevel gearbox mounted in a housing, of which the driven gear has a vertical shaft to which the rod is attached, while the drive gear has a horizontal shaft which projects from the housing and carries the foot actuator.

Nach einem weiteren Merkmal der Erfindung ist das Fußbetäti ­gungsorgan ein um die Achse der horizontalen Welle verschwenkba­rer, zweiarmiger Hebel, der abnehmbar an der Welle befestigt ist.According to a further feature of the invention, the Fußbetäti supply member is a pivotable about the axis of the horizontal shaft, two-armed lever, which is removably attached to the shaft.

Es ist besonders vorteilhaft, wenn das Gehäuse Mittel zur Befe­stigung des Ständers aufweist und wenn in Weiterbildung der Er­findung die Stange lösbar an der vertikalen Welle befestigt ist. Mit diesen Maßnahmen sind ein rasches Zerlegen und Zusam­menbauen möglich, ohne daß hierfür Werkzeuge erforderlich sind. Außerdem kann ein herkömmlicher Notenständer, der von seinem Dreifuß abgenommen ist, in das Gehäuse eingesetzt werden.It is particularly advantageous if the housing has means for fastening the stand and if, in a development of the invention, the rod is detachably fastened to the vertical shaft. With these measures, quick disassembly and assembly are possible without the need for tools. In addition, a conventional music stand, which is removed from its tripod, can be inserted into the housing.

In Weiterbildung der Erfindung ist vorgesehen, den horizontalen Arm und/oder die vertikale Stange teleskopisch verstellbar aus­zubilden, um die Vorrichtung den örtlichen Gegebenheiten anpas­sen zu können.In a further development of the invention, it is provided that the horizontal arm and / or the vertical rod can be made telescopically adjustable in order to be able to adapt the device to the local conditions.

Zur Anpassung des Wendeorgans an unterschiedliche Abmessungen des Schriftgutes ist es vorteilhaft, wenn dieses an einem Bol­zen befestigt ist, der wahlweise in eine von mehreren Bohrungen des Armes einsteckbar ist.To adapt the turning organ to different dimensions of the writing material, it is advantageous if it is fastened to a bolt which can optionally be inserted into one of several bores in the arm.

Die Erfindung ist nachstehend an drei Ausführungsbeispielen er­läutert, die in der Zeichnung dargestellt sind.The invention is explained below using three exemplary embodiments, which are shown in the drawing.

  • Figure 7 shows the enlarged view of a turning organ.

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 mehrerer derartiger Bohrung 34, so daß die Position des Bügels 26 am Arm 36 an die Abmessungen 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 freely rotatably inserted in a bore 34 in a horizontal arm 36. The arm 36 has several such holes 34 so that the position of the bracket 26 on the arm 36 can be adapted to the dimensions 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 beyond the front end face 52 of the housing 10 and carries a foot actuating element 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 150o 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. 1, as a result of which the rod 38 is moved via the bevel gear mechanism 46 is rotated by about 150 o in the direction of arrow S. This also turns 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 Figure 4, the vertical rod 38 is telescopically adjustable and for this purpose has a thinner rod part 38 ', which sits by means of a clamping screw 56 in the lower part of the rod 38. In a corresponding manner, the arm 36 is horizontally telescopically adjustable and sits via a clamping screw 58 on a thinner arm portion 36 'which is integrally formed 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 closely next to one another and grip the sheet not shown, which is to be turned very tightly, preferably with little spring pressure so that it does not get caught on a projection 60 of the music stand 18 when it is turned and slips out of the strap 26.

In Figur 4 ist die Möglichkeit gezeigt, den hohlen Fuß 16 des handelsüblichen Notenständers 18, dessen hochgeklapptes Drei­bein 62 angedeutet ist, auf einen mittels der Feststellschraube 22 im Gehäuse 10 befestigten Stift 64 aufzusetzen und auf die­sem über eine Klemmschraube 66 zu fixieren.FIG. 4 shows the possibility of placing the hollow foot 16 of the commercially available music stand 18, the raised tripod 62 of which is indicated, on a pin 64 fastened in the housing 10 by means of the locking screw 22 and fixing it on this 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 o. dgl. zu verpacken.Figures 5 to 7 show a particularly advantageous embodiment in which the two front feet 12 'of the housing 10 about vertical axes 68 are pivotally attached to this. 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 dismantled in order to pack it in a suitcase or the like.

Weiter ist zu erklennen, 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 Armes 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. To fold the device, the sliding bearing 78 can be pivoted downward about the axis of the clamping screw 76 in the direction of the arrow. In a horizontal bore of the sliding bearing 78, the arm 36˝, which is designed as a rod, is adjustable and can be fixed in the central region by a locking screw 80 in the sliding bearing 78. The arm 36˝ carries at both ends a turning member, which consists of two clamping plates 28, which are fixed by means of a clamping screw 82 in a bracket 84, which projects downward at the associated end of the arm 36˝.

Mit der Vorrichtung nach den Figuren 5 bis 7 ist es möglich, zwei Notenständer gleichzeitig zu bedienen, wobei ein Notenstän­der auf einen Bolzen 86 des Gehäuses 10 gesteckt und dort mittels der Feststellschraube 22 festgeklemmt ist, während der zweite Notenständer 18′, wie in Figur 6 angedeutet, hinter das Gehäuse 10 gestellt ist.With the device according to FIGS. 5 to 7, it is possible to operate two music stands at the same time, one music stand being plugged onto a bolt 86 of the housing 10 and clamped there by means of the locking screw 22, while the second music stand 18 ', as in FIG. 6 indicated, is placed behind the housing 10.

Selbstverständlich kann die Vorrichtung gemäß der Erfindung auch zusammen mit anderen Notenständern verwendet werden, bei­spielsweise solchen, die an einer Heimorgel oder einem anderen Instrument angebracht sind. Wesentlich ist nur, daß dieses so viel Bodenfreiheit hat, daß das Gehäuse 10 darunter Platz hat. Die Teleskopausführung des Armes 36, 36′ und der Stange 38, 38′ erlaubt dann eine bequeme Anpassung an die Maße des Instrumen­tes und die Lage des Notenständers.Of course, the device according to the invention can also be used together with other music stands, for example those that are attached to a home organ or another instrument. It is only important that this has so much ground clearance that the housing 10 has space underneath. The telescopic design of the arm 36, 36 'and the rod 38, 38' then allows easy adjustment to the dimensions of the instrument and the position of the music stand.
