Abstract

A device carried on a moving vehicle for creating marking lines, which are a plurality of elements and are made of a highly viscous marking material, on a surface that is to be marked. The device includes a housing formed by walls and a discharge slot formed in at least one of the walls of the housing and extending transversely to a direction of movement of the vehicle, the discharge slot being limited in extent by a front discharge slot edge and a rear discharge slot edge, seen in the direction of movement of the vehicle. A pressurized material supply line leads to an interior of the housing. A rotatable hollow cylinder formed of a jacket is located in the interior of the housing and is arranged to rotate with the movement of the vehicle carrying the device. The cylinder is provided with a plurality of passages through the jacket, which, depending on a rotary position of the cylinder, establish a connection between the pressurized material supply line and the discharge slot. The rotary cylinder is positioned in the housing with an outer circumferential surface of its jacket spaced at a distance from the walls of the housing and essentially forms a sealing gap only in an area of the discharge slot edges.

Description

Die Erfindung bezieht sich auf Vorrichtung zur Erzeugung von Markierungslinien aus hochviskosem Markierungsmaterial auf einer zu markierenden Oberfläche, insbesondere Straßenoberfläche, wobei mit der Vorrichtung unter Druck befindliches Markierungsmaterial durch einen Auslass, der geöffnet und geschlossen werden kann, unter Fortbewegung relativ zur Oberfläche austragbar ist, wobei die Vorrichtung einen dem Auslass vorgeschalteten oder den Auslass bildenden Durchlass für das Markierungsmaterial aufweist, wobei der Durchlassquerschnitt des Durchlasses durch ein erstes, festes Durchlasselement und ein daran zusammenwirkend anliegendes, relativ dazu in einer Anlageebene rotierend bewegbares zweites Durchlasselement bei der Fortbewegung der Vorrichtung relativ zur Oberfläche periodisch veränderbar ist, wobei die Vorrichtung ein Gehäuse mit einem das erste, feste Durchlasselement bildenden Gehäuseboden mit einer in Fortbewegungsrichtung gesehen quer angeordneten, schlitzförmigen Durchlassöffnung aufweist, wobei der Durchlassquerschnitt des Durchlasses durch einen um eine quer zur Fortbewegungsrichtung verlaufende Achse rotierend bewegbaren, das zweite Durchlasselement bildenden Hohlzylinder mit in seiner Mantelfläche angeordneten Durchlassöffnungen veränderbar ist.The invention relates to apparatus for producing marking lines of highly viscous marking material on a surface to be marked, in particular road surface, wherein the marking material under pressure with the device through an outlet, which can be opened and closed, while being moved relative to the surface can be discharged, wherein the device has a passage for the marking material upstream of the outlet or the outlet, wherein the passage cross section of the passage through a first, fixed passage member and cooperating thereto second, relatively rotatable in a plant plane second passage member during movement of the device relative to the surface can be changed periodically, wherein the device comprises a housing having a housing base forming the first, fixed passage element with a slot-shaped D arranged transversely in the direction of travel passage opening, wherein the passage cross-section of the passage through a about a transverse axis to the direction of movement rotatably movable, the second passage member forming hollow cylinder is variable with arranged in its lateral surface passage openings.

Das Dokument WO-A-03 006 744 zeigt eine Vorrichtung mit den vorstehend angegebenen Merkmalen. Ein einen Teil dieser Vorrichtung bildender Rotor kann rohrförmig, also ein Hohlzylinder sein, der in seinem Umfang Löcher aufweist. In der Vorrichtung wirkt der Hohlzylinder über seinen gesamten Umfang dichtend mit einer verdrehfest angeordneten Hülse zusammen.The document WO-A-03 006 744 shows a device with the features indicated above. A part of this device forming rotor can tubular, so a Be hollow cylinder having holes in its periphery. In the device, the hollow cylinder acts sealingly over its entire circumference with a sleeve arranged in a rotationally fixed manner.

Das Dokument DE-A-37 28 250 beschreibt eine Vorrichtung an einem Arbeitsgerät zum Auftragen von Farbmasse in kaltem oder erhitzen Zustand, vorzugsweise auf Fahrbahnoberflächen. Diese Vorrichtung verwendet einen rotierenden Zylinder, wobei dieser hier eine massive Walze mit Zähnen oder Flügeln ist, die zwischen sich Auskehlungen oder Fächer am Außenumfang der Walze bilden. Die Walze ist von dem Vorratsbehälter teilweise umschlossen; gemäß dem Ausführungsbeispiel ist die Walze über annähernd ihren halben Umfang an einen Behälterboden und an einen Rundschieber dichtend angelegt.The document DE-A-37 28 250 describes a device on a working device for applying paint mass in a cold or heated state, preferably on road surfaces. This device uses a rotating cylinder, which is here a solid roller with teeth or wings, which form between them grooves or compartments on the outer circumference of the roller. The roller is partially enclosed by the reservoir; According to the embodiment, the roller is applied sealingly over approximately half its circumference to a container bottom and to a round slide.

Es ist daher die Aufgabe der Erfindung, eine Vorrichtung zu schaffen, die auf einfachste Weise zur Erzeugung von herkömmlichen, vollflächigen glatten Markierungslinien umrüstbar ist.It is therefore the object of the invention to provide a device which in the simplest way for the production of conventional, full-surface smooth marking lines can be converted.

Die Lösung der Aufgabe erfolgt mit einer Vorrichtung der eingangs genannten Art, die dadurch gekennzeichnet ist, dass zur Erzeugung von aus einer Vielzahl von Elementen bestehenden Markierungslinien der Hohlzylinder mit dem Außenumfang seiner Mantelfläche an zwei die schlitzförmige Durchlassöffnung im Gehäuseboden in Fortbewegungsrichtung gesehen vorne und hinten begrenzenden Durchlassöffnungskanten gleitend anliegt und dass zur Erzeugung von vollflächigen glatten Markierungslinien der Hohlzylinder in eine zu den Durchlassöffnungskanten beabstandete Position verlagerbar ist.The object is achieved with a device of the type mentioned, which is characterized in that for generating of a plurality of elements existing marking lines of the hollow cylinder with the outer periphery of its lateral surface at two the slot-shaped passage opening in the housing bottom in the direction of travel front and rear limiting Durchlassöffnungskanten slidingly abuts and that for the production of full-surface smooth marking lines of the hollow cylinder is displaceable in a position spaced from the passage opening edge position.

Die Durchlassöffnungskanten bilden einen Teil des Gehäusebodens und sorgen, wenn die Vorrichtung für die Erzeugung von aus einer Vielzahl von Elementen bestehenden Markierungslinien eingestellt ist, im Zusammenwirken mit dem Außenumfang des Hohlzylinders für die erforderliche Abdichtung zwischen den relativ zueinander bewegten Vorrichtungsteilen. So wird ein unkontrollierter Austritt von Markierungsmaterial auf anderen Wegen als durch die vorgesehenen Durchlassöffnungen vermieden. Der Vorteil der erfindungsgemäßen Vorrichtung besteht darin, dass mit derselben Vorrichtung wahlweise verschiedenen Markierungslinienarten hergestellt werden können, wobei das Umstellen von einer Linienart zu einer anderen Linienart sehr einfach ist, weil nur der Hohlzylinder gehoben oder gesenkt werden muss.The passageway opening edges form part of the housing bottom and, when the device is configured to produce marking lines consisting of a plurality of elements, in cooperation with the outer circumference of the hollow cylinder for the required sealing between the relatively moving device parts. Thus, an uncontrolled leakage of marking material is avoided in other ways than through the provided passage openings. The advantage of the device according to the invention is that with the same device optionally different types of marking line can be produced, the switch from one line type to another type of line is very simple, because only the hollow cylinder raised or lowered must become.

Weiter wird vorgeschlagen, dass die Durchlassöffnungen im Hohlzylinder durch sowohl in dessen Umfangsrichtung als auch in dessen Axialrichtung versetzt zueinander angeordnete, runde oder mehreckige Öffnungen gebildet sind. Mit diesem Hohlzylinder lassen sich Markierungslinien aus einer Vielzahl von Markierungsmaterialpunkten oder -tropfen bilden.It is further proposed that the passage openings in the hollow cylinder are formed by round or polygonal openings arranged offset from one another both in its circumferential direction and in its axial direction. With this hollow cylinder, marking lines can be formed from a plurality of marking material dots or drops.

Alternativ dazu sind die Durchlassöffnungen im Hohlzylinder durch in dessen Umfangsrichtung versetzt zueinander angeordnete, parallel zur Axialrichtung des Hohlzylinders verlaufende schlitzförmige Öffnungen gebildet. Mit diesem Hohlzylinder lassen sich Markierungslinien aus einer Vielzahl von wulstförmigen, quer zur Markierungslinienlängsrichtung ausgerichteten Markierungsmaterialelementen erzeugen.Alternatively, the passage openings in the hollow cylinder by offset in the circumferential direction of each other, formed parallel to the axial direction of the hollow cylinder extending slot-shaped openings. With this hollow cylinder, marking lines can be produced from a multiplicity of bead-shaped marking material elements oriented transversely to the marking line longitudinal direction.

Bevorzugt ist der die Durchlassöffnung im Gehäuseboden bildende, sich quer zur Fortbewegungsrichtung erstreckende Schlitz mit einer Länge, die einer gewünschten Markierungslinienbreite entspricht, ausgebildet.Preferably, the slot forming the passage opening in the housing bottom and extending transversely to the direction of travel is formed with a length corresponding to a desired marking line width.

Wenn mit der Vorrichtung Markierungslinien unterschiedlicher Breite erzeugt werden sollen, dann kann der Schlitz mit einer verstellbaren Einrichtung zur Veränderung und Festlegung seiner Länge ausgestattet sein.If marking lines of different widths are to be produced with the device, then the slot may be equipped with an adjustable device for changing and fixing its length.

Weiter ist vorgesehen, dass der Durchlassöffnung im Gehäuseboden mindestens ein Auf-/Zu-Schieber zugeordnet ist, der mindestens eine der zwei Durchlassöffnungskanten bildet, wobei die Durchlassöffnungskante in einer zur Fortbewegungsrichtung parallelen Verstellrichtung verstellbar ist. Mittels dieses Auf-/Zu-Schiebers kann bei Bedarf, insbesondere bei Unterbrechungen in der zu erzeugenden Markierungslinie oder an einem Markierungslinienende, der Auslass schnell und vollständig und unabhängig vom Hohlzylinder geschlossen werden und, insbesondere am Beginn einer zu erzeugenden Markierungslinie, ebenso schnell geöffnet werden, wonach dann der Austrag von Markierungsmaterial durch den Hohlzylinder gesteuert wird. Die auf diese Weise erzeugten Linienanfänge und Linienenden weisen dann auch bei aus einer Vielzahl von Elementen bestehenden Markierungslinien die gleichen kurzen Übergangszonen auf wie herkömmliche vollflächige, mit einem zu öffnenden und zu schließenden Materialaustragschlitz erzeugte Markierungslinien.It is further provided that the passage opening in the housing bottom is assigned at least one open / close slide, which forms at least one of the two passage opening edges, wherein the passage opening edge is adjustable in an adjustment direction parallel to the direction of travel. By means of this open / close slide can at Needed, especially at interruptions in the marking line to be produced or at a marking line end, the outlet are closed quickly and completely and independently of the hollow cylinder and, especially at the beginning of a marking line to be generated, opened just as quickly, after which then the discharge of marking material through the hollow cylinder is controlled. The line beginnings and line ends produced in this way then also have the same short transition zones in the case of marking lines comprising a plurality of elements, as are conventional full-surface marking lines produced with a material discharge slot to be opened and closed.

Der Hohlzylinder kann z.B. durch einen geeigneten motorischen Drehantrieb, vorzugsweise mit variabler Drehzahl, in Drehung versetzt werden. Um bei der Vorrichtung bei Änderungen der Geschwindigkeit der Fortbewegung relativ zu der zu markierenden Oberfläche unerwünschte Änderungen des Erscheinungsbildes der Markierungen zu vermeiden, ist aber bevorzugt vorgesehen, dass die Vorrichtung einen ein Antreiben des Hohlzylinders mit zu einer Fortbewegungsgeschwindigkeit der Vorrichtung relativ zur Oberfläche proportionaler Drehzahl gewährleistenden Antrieb aufweist. Die Proportionalität des Hohlzylinderdrehantriebs zur Fortbewegungsgeschwindigkeit der Vorrichtung kann z.B. dadurch einfach erreicht werden, dass der Hohlzylinderdrehantrieb von einem von mehreren die Vorrichtung tragenden, auf der zu markierenden Oberfläche abrollenden Rädern oder von einem mit mindestens einem der Räder gekoppelten Fahrantrieb der Vorrichtung abgenommen wird.The hollow cylinder may e.g. be rotated by a suitable motorized rotary drive, preferably with variable speed, in rotation. However, in order to avoid undesirable changes in the appearance of the markings in the device with changes in the speed of travel relative to the surface to be marked, it is preferred that the device provide rotational speed proportional to the speed of movement of the device relative to the surface Drive has. The proportionality of the hollow cylinder rotary drive to the speed of travel of the device may e.g. be achieved simply by the hollow cylindrical rotary drive of one of several device supporting, rolling on the surface to be marked wheels or by a coupled to at least one of the wheels drive the device is removed.

Um ein und dieselbe Vorrichtung möglichst vielseitig, das heißt für die Erzeugung vieler unterschiedlicher Arten von Markierungslinien, einsetzen zu können, ist bevorzugt vorgesehen, dass das Gehäuse oder der Gehäuseboden und/oder der Hohlzylinder jeweils einen austauschbaren Vorrichtungsteil bilden. Der Benutzer der Vorrichtung muss dann nur vor deren Einsatz die passenden Vorrichtungsteile für die jeweils zu erzeugende Markierungslinie auswählen und einbauen. Dabei werden bevorzugt werkzeuglos herstellbare und lösbare Verbindungen oder Verbindungsmittel eingesetzt. Mehrere Vorrichtungen für unterschiedliche Markierungslinien werden nicht mehr benötigt.In order to use one and the same device as versatile as possible, that is to say for the generation of many different types of marking lines, it is preferred provided that the housing or the housing bottom and / or the hollow cylinder each form an exchangeable device part. The user of the device must then select and install the appropriate device parts for the respective marking line to be generated only before their use. In this case, preference is given to using tool-less producible and releasable connections or connecting means. Several devices for different marking lines are no longer needed.

Die Vorrichtung ist, unabhängig von ihrer konkreten Ausführung, zweckmäßig auf einem selbstfahrenden Fahrzeug mit Rädern, Antrieb und Lenkung oder alternativ auf einem gezogenen Fahrzeug mit Rädern, also einem Anhänger, angeordnet.The device is, regardless of their specific design, expediently arranged on a self-propelled vehicle with wheels, drive and steering or alternatively on a towed vehicle with wheels, so a trailer.

Sollen heiße, bis zu ihrer Applikation zu erwärmende Markierungsmaterialien verarbeitet werden, genügt eine Beheizung lediglich des Gehäuses.If hot marking materials to be heated up to their application are to be processed, heating of the housing is sufficient.

Die Länge der Durchlassöffnung 21 in Querrichtung zur Fortbewegungsrichtung 8 entspricht der Breite einer zu erzeugenden Markierungslinie 7.The housing 11 has on its side facing the surface 6 on its housing bottom 12 two in and against the direction of travel 8 displaceable open / close or shutter slide 5, which each form an adjustable passage opening edge 25. By means of these slides 5 can be opened or closed by means of conventional actuating means, here in the form of pneumatic cylinders 50, a transversely to the direction of travel 8 extending, a passage opening 21 forming slot at the bottom 12 of the housing 11. The length of the passage opening 21 in the transverse direction to the direction of movement 8 corresponds to the width of a marking line 7 to be produced.

In der Kammer 11' befindet sich ein in seinem Mantel 41 mit Durchlassöffnungen 24 versehener Hohlzylinder 4 mit zwei Wellenzapfen 47, die in Wellenlagern 48 gelagert sind. Dabei sind die Durchlassöffnungen 24 in Umfangsrichtung und Axialrichtung des Hohlzylinders 4 voneinander beabstandet und verteilt und liegen auf mehreren Umfangslinien nebeneinander, wie die Figur 5 deutlich zeigt.In the chamber 11 'is a provided in its jacket 41 with openings 24 hollow cylinder 4 with two shaft journals 47, which are mounted in shaft bearings 48. In this case, the passage openings 24 in the circumferential direction and axial direction of the hollow cylinder 4 are spaced apart and distributed and lie on several circumferential lines next to each other, like the FIG. 5 clearly shows.

Die Wellenlager 48 sind gegenüber seitlichen Gehäusewänden 13 des Gehäuses 11 vertikal verschiebbar und lassen sich, wie Figur 5 zeigt, mit Hilfe von zwei Verstelleinrichtungen 46 mit je einem Handrad und je einer Gewindespindel in der Höhe verstellen. Hierdurch kann der Hohlzylinder 4 zwischen der in der rechten Hälfte von Figur 5 dargestellten, an den Durchlassöffnungskanten 25 anliegenden Position und der in der linken Hälfte von Figur 5 dargestellten, von den Durchlassöffnungskanten 25 beabstandete Position verschoben werden. In dieser beabstandeten Position gelangt das durch den Materialzulauf 10 zugeführte Markierungsmaterial vom Hohlzylinder 4 nicht behindert zu der Durchlassöffnung 21 und im geöffneten Zustand der Auf-/Zu-Schieber 5 als zusammenhängendes Band auf die Straßenoberfläche 6 und bildet dort eine durchgehende, glatte Markierungslinie 7.The shaft bearings 48 are vertically displaceable relative to the side of the housing walls 13 of the housing 11 and can be, as FIG. 5 shows, with the help of two adjusting devices 46 with one handwheel and one threaded spindle each. As a result, the hollow cylinder 4 between the in the right half of FIG. 5 shown, applied to the passage opening edge 25 position and in the left half of FIG. 5 shown, spaced from the passage opening edges 25 position to be moved. In this spaced-apart position, the marking material fed through the material feed 10 does not reach the passage opening 21 in a discrete manner from the hollow cylinder 4 and, when opened, the open / close slide 5 as a coherent band on the road surface 6 and forms a continuous, smooth marking line 7 there.

In der in Figur 3 und im rechten Teil von Figur 5 dargestellten unteren Position des Hohlzylinders 4 gelangt das Markierungsmaterial nur durch den Innenraum des Hohlzylinders 4 und dann durch die im Bereich der Durchlassöffnung 21 nach außen hin gerade freien Querschnitte der Durchlassöffnungen 24 im Hohlzylinder 4 portionsweise in exakter und reproduzierbarer Dosierung aus der Kammer 11' auf die Oberfläche 6 und bildet dort bei gleichzeitiger Bewegung der Vorrichtung 1 in Fortbewegungsrichtung 8 die tropfenförmigen Elemente 70 der Markierungslinie 7.In the in FIG. 3 and in the right part of FIG. 5 shown lower position of the hollow cylinder 4 passes the marking material only through the interior of the hollow cylinder 4 and then through the in the region of the passage opening 21 outwardly straight free cross sections of the passage openings 24 in the hollow cylinder 4 in portions in exact and reproducible dosage from the chamber 11 'on the Surface 6 and forms there with simultaneous movement of the device 1 in the direction of travel 8, the teardrop-shaped elements 70 of the marking line. 7

Figur 6 zeigt ein Beispiel für eine Vorrichtung 1, die in weiten Teilen mit der Vorrichtung gemäß den Figuren 3 bis 5 übereinstimmt. Unterschiedlich ist die Ausführung des Hohlzylinders 4, der bei dem Beispiel nach Figur 6 in seinem Mantel 41 schlitzförmige Durchlassöffnungen 24 aufweist. Die Durchlassöffnungen 24 verlaufen parallel zueinander und parallel zur Axialrichtung des Hohlzylinders 4. In der in Figur 6 dargestellten unteren Position des Hohlzylinders 4 liegt dieser mit dem Außenumfang seines Mantels 41 an den Durchlassöffnungskanten 25 der beiden Schieber 5 an. Die Durchlassöffnungskanten 25 begrenzen auch hier eine als Schlitz ausgebildete Durchlassöffnung 21 im Boden 12 des Gehäuses 11. FIG. 6 shows an example of a device 1, which in large parts with the device according to the FIGS. 3 to 5 matches. Different is the embodiment of the hollow cylinder 4, which in the example FIG. 6 has slot-shaped passage openings 24 in its jacket 41. The passage openings 24 extend parallel to one another and parallel to the axial direction of the hollow cylinder 4. In the in FIG. 6 shown lower position of the hollow cylinder 4 is this with the outer periphery of its shell 41 at the passage opening edge 25 of the two Slide 5 on. The passage opening edges 25 also delimit a passage opening 21 formed as a slot in the bottom 12 of the housing 11.

Mit der Vorrichtung gemäß Figur 6 lässt sich aus der Kammer 11' des Gehäuses 11 unter Druck stehendes Markierungsmaterial in Form von quer zur Fortbewegungsrichtung (die Fortbewegungsrichtung verläuft in Figur 6 senkrecht zur Zeichnungsebene) und parallel zueinander verlaufenden Wülsten erzeugen, wobei die einzelnen Wülste jeweils ein Element 70 der Markierungslinie 7 bilden.With the device according to FIG. 6 can be from the chamber 11 'of the housing 11 under pressure marking material in the form of transverse to the direction of movement (the direction of travel extends in FIG. 6 perpendicular to the plane of the drawing) and mutually parallel beads produce, wherein the individual beads each form an element 70 of the marking line 7.

Wenn bei der Vorrichtung 1 gemäß Figur 6 der Hohlzylinder 4 mit Hilfe der Verstelleinrichtungen 46 in seine angehobene Position verstellt ist, arbeitet die Vorrichtung 1 gemäß Figur 6 so wie die Vorrichtung 1, die in Figur 4 und in der linken Hälfte der Figur 5 dargestellt und erläutert ist.When in the device 1 according to FIG. 6 the hollow cylinder 4 is adjusted by means of the adjusting means 46 in its raised position, the device 1 operates according to FIG. 6 as the device 1, the in FIG. 4 and in the left half of the FIG. 5 is shown and explained.

Die Länge L der Elemente 70 in Längsrichtung der Markierungslinie 7 hängt ab vom Verhältnis der Fortbewegungsgeschwindigkeit der Vorrichtung 1 zur Drehgeschwindigkeit des Hohlzylinders 4. Je geringer die Drehgeschwindigkeit im Verhältnis zur Fortbewegungsgeschwindigkeit ist, um so größer ist die Länge L der einzelnen Elemente 70, wie dies in den Figuren 1 und 2 veranschaulicht ist.The length L of the elements 70 in the longitudinal direction of the marking line 7 depends on the ratio of the speed of movement of the device 1 to the rotational speed of the hollow cylinder 4. The lower the rotational speed in relation to the speed of travel, the greater the length L of the individual elements 70, as this in the FIGS. 1 and 2 is illustrated.

Bei den Vorrichtungen 1 gemäß den Figuren 3 bis 6 sollte die Drehzahl des Hohlzylinders 4 bevorzugt proportional zur Fortbewegungsgeschwindigkeit der Vorrichtung 1 relativ zu der zu markierenden Oberfläche 6 sein, um geschwindigkeitsunabhängig gleichmäßig lange Elemente 70 zu erzeugen. Dies kann gemäß Figur 7 in einfacher Weise erreicht werden durch ein auf der Oberfläche 6 abrollendes Reibrad 43, das mit Hilfe einfacher Übertragungsmittel, hier in Gestalt eines Kettentriebes, den Hohlzylinder 4 proportional zur Fortbewegungsgeschwindigkeit der Vorrichtung 1 antreibt. Der Kettentrieb umfasst eine Kette 44 und zwei Kettenräder 45 und 45'. Das Kettenrad 45 ist verdrehfest mit dem Reibrad 43 verbunden, das Kettenrad 45' ist verdrehfest mit einem der Wellenzapfen 47 des Hohlzylinders 4 verbunden.In the devices 1 according to the FIGS. 3 to 6 the speed of the hollow cylinder 4 should preferably be proportional to the speed of movement of the device 1 relative to the surface 6 to be marked in order to produce uniformly long elements 70 regardless of speed. This can be done according to FIG. 7 be achieved in a simple manner by a rolling on the surface 6 friction wheel 43, which by means of simple transmission means, here in the form of a chain drive, the hollow cylinder 4 proportional to the speed of movement of the device 1 drives. The chain drive comprises a chain 44 and two sprockets 45 and 45 '. The sprocket 45 is rotationally connected to the friction wheel 43, the sprocket 45 'is rotationally connected to one of the shaft journals 47 of the hollow cylinder 4.

Das Verhältnis der Drehgeschwindigkeit des Hohlzylinders 4 zur Fortbewegungsgeschwindigkeit der Vorrichtung 1, das heißt die Länge L der Elemente 70, lässt sich mit der Kettentriebübersetzung durch entsprechende Auswahl der Kettenräder 45 und 45' einstellen, wobei das Getriebe auch zwischen verschiedenen Übersetzungen umschaltbar ausgeführt sein kann.The ratio of the rotational speed of the hollow cylinder 4 to the speed of movement of the device 1, that is, the length L of the elements 70, can be adjusted with the chain drive ratio by appropriate selection of the sprockets 45 and 45 ', wherein the transmission can be made switchable between different translations.
