Description

Beschreibung description
FreizeitsportanlageLeisure sports facility
Die Erfindung betrifft eine Freizeitsportanlage mit zumindest einem entlang eines mit Gefälle verlaufenden Fahrweges durch Schwerkraft fahrbaren Fahrzeug, welches hinsichtlich seiner Geschwindigkeit vom Fahrer individuell zu steuern ist.The invention relates to a recreational sports facility with at least one vehicle that can be driven by gravity along a slope that runs on a gradient and that can be individually controlled by the driver with regard to its speed.
Eine solche Freizeitsportanlage ist beispielsweise in der US-A-4, 417, 740 beschrieben. Der Fahrweg wird bei ihr durch eine nach oben hin offene Rinne gebildet, in welcher die Fahrzeuge zu fahren vermögen und durch deren quer zur Haupterstreckungsrichtung verlaufende Krümmung die Fahrzeuge am Verlassen des Fahrweges gehindert werden.Such a recreational sports facility is described for example in US-A-4, 417, 740. The route is formed by an upwardly open channel, in which the vehicles are able to drive and whose curvature, which runs transverse to the main direction of extension, prevents the vehicles from leaving the route.
Eine Freizeitsportanlage, wie sie in der genannten US-A- 4.417,740 beschrieben ist, beansprucht für ihren Fahrweg relativ viel Platz. Sie hat sicherheitstechnisch den Nachteil, dass bei zu hoher Geschwindigkeit und bei einer ungeschickten Gewichtsverlagerung des Benutzers eines Fahrzeugs dieser Freizeitsportanlage das Fahrzeug doch aus der Rinne herausgelangen kann, was zu ernsten Verletzungen des Fahrers und Schäden am Fahrzeug führen würde. Hinzu kommt, dass die Fahrzeuge mit beträchtlichem Abstand fahren müssen, da ein selbsttätiges Abbremsen bei einer gefährlichen Annäherung aufgrund unterschiedlicher Fahrgeschwindigkeiten mit vertretbarem Aufwand nicht zu verwirklichen ist.A recreational sports facility, as described in said US-A-4,417,740, takes up a relatively large amount of space for its route. From a safety point of view, it has the disadvantage that if the speed of the user of a vehicle in this recreational sports facility is shifted too quickly and the weight is inappropriately shifted, the vehicle can nevertheless get out of the channel, which would lead to serious injuries to the driver and damage to the vehicle. In addition, the vehicles have to drive a considerable distance, since an automatic braking in the event of a dangerous approach due to different driving speeds cannot be achieved with reasonable effort.
Auf Festplätzen sind sogenannte Achterbahnen gebräuchlich, bei denen Fahrzeuge auf Fahrschienen abgestützt und geführt sind. Solche Freizeitanlagen erlauben es, die Fahrzeuge dicht hintereinander fahren zu lassen und bei Bedarf automatisch abzubremsen, sind jedoch sehr aufwendig gestaltet, so dass nach dem Prinzip von Achterbahnen gestaltete Freizeitsportanlagen bislang nicht auf Berghängen errichtet wurden, um längere Abwärtsfahren zu ermöglichen. Außerdem können Achterbahnwagen nicht individuell abgebremst werden.So-called roller coasters, in which vehicles are supported and guided on rails, are common on fairgrounds. Such leisure facilities allow the However, letting vehicles drive close behind one another and braking automatically when required is very complex, so that recreational sports facilities designed on the principle of roller coasters have not yet been built on mountain slopes to enable longer descents. In addition, roller coaster cars cannot be braked individually.
Der Erfindung liegt das Problem zugrunde, eine möglichst einfach gestaltete Freizeitsportanlage der eingangs genannten Art so auszubilden, dass sie sich zur Errichtung auf Berghängen eignet und dabei möglichst wenig in die Natur eingreift, ohne dass die Sicherheit der Benutzer der Freizeitsportanlage beeinträchtigt wird.The invention is based on the problem of designing a leisure sports facility of the type mentioned at the outset that is as simple as possible in such a way that it is suitable for erection on mountain slopes and thereby interferes with nature as little as possible without the safety of the users of the leisure sports facility being impaired.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Fahrweg zwei als Rohre ausgebildete Fahrschienen hat, auf welchen das Fahrzeug mit Tragrädern oder Kufen abgestützt ist, dass die Rohre von quer verlaufenden, von Ständern abgestützten Tragkörpern auf einen genauen, gegenseitigen Abstand gehalten sind und dass diese Ständer an ihrer Unterseite Pratzenfüße zum Abstützen auf dem Erdboden aufweisen.This problem is solved according to the invention in that the guideway has two rails designed as tubes, on which the vehicle is supported with carrying wheels or runners, that the tubes are kept at a precise mutual distance from one another by supporting bodies which are supported by stands, and that these Stand on its underside have claw feet for support on the ground.
Ein solcher durch zwei parallele Rohre als Fahrschienen gebildeter Fahrweg kann sehr einfach mit wechselnden Gefällen und Kurven verlegt werden, wobei bei Kurven sehr leicht eine Überhöhung der jeweils kurvenäußeren Führungsschiene möglich ist. Wenn sich die Tragräder oder Kufen nicht flächig auf ebenen Laufflächen, sondern auf im Querschnitt kreisförmigen Rohren abstützen, kommt es nur zu einer linienförmigen Berührung, wodurch die Tragräder sehr leicht rollen oder die Kufen leicht gleiten und es in Kurven zu keinem Verklemmen kommen kann, weil die Fahrschienen keine stets zu den Tragrädern oder Kufen hin ausgerichtete Laufflächen haben müssen. Da die Tragkörper mit den Fahrschienen von Ständern abgestützt sind, braucht die Freizeitsportanlage den Erdboden nur mit den Pratzenfüßen zu berühren, so dass beispielsweise eine Grasnarbe unterhalb der Anlage nur unbedeutend beeinträchtigt wird. Hervorzuheben ist auch, dass die neuerungsgemäße Freizeitsportanlage keinerlei Betonfundamente oder sonstige, bleibend im Boden zu verankernde Betonteile benötigt. Bei einem geringen Gefälle genügt es, wenn die Freizeitsportanlage lediglich frei auf dem Boden aufsteht, während man bei einem größeren Gefälle mit einzelnen Erdnägeln die Freizeitsportanlage zusätzlich sichern kann.Such a guideway formed by two parallel pipes as guideways can be laid very easily with changing slopes and curves, it being very easy to increase the respective outer guideway on curves. If the carrying wheels or runners are not supported flatly on flat treads, but on pipes with a circular cross-section, there is only a linear contact, which means that the carrying wheels roll very easily or the runners slide easily and there is no jamming in curves because the running rails do not have to have running surfaces always aligned with the carrying wheels or runners. Since the Support body with the rails are supported by stands, the recreational sports facility only needs to touch the ground with its claw feet, so that, for example, a turf underneath the facility is only slightly affected. It should also be emphasized that the new recreational sports facility does not require any concrete foundations or other concrete parts to be permanently anchored in the ground. In the case of a slight gradient, it is sufficient if the recreational sports facility only stands up freely on the ground, while on a larger gradient, the recreational sports facility can be additionally secured with individual pegs.
Die Fahrzeuge könnten die Fahrschienen zugleich zur Führung benutzen. Dann können jedoch Platzprobleme bei der Anordnung der Führungseinrichtungen und der Bremse entstehen. Diese lassen sich vermeiden, wenn gemäß einer Weiterbildung der Erfindung die Tragkörper zwischen den Fahrschienen zwei parallel zu den Fahrschienen verlaufende Führungsschienen aufweisen und wenn die Fahrzeuge nach unten zwischen die Führungsschienen ragende Führungsausleger haben, welche jeweils L-förmig ausgebildet sind und mit einem horizontalen Schenkel unter jeweils eine Führungsschiene greifen.The vehicles could also use the rails for guidance. However, space problems can then arise in the arrangement of the guide devices and the brake. These can be avoided if, according to a further development of the invention, the supporting bodies between the travel rails have two guide rails running parallel to the travel rails and if the vehicles have guide arms projecting downwards between the guide rails, each of which is L-shaped and with a horizontal leg underneath grasp one guide rail each.
Die Mittel zum Abbremsen der einzelnen Fahrzeuge sind besonders einfach und wirkungsvoll gestaltet, wenn die Fahrzeuge an jeder Seite oberhalb jeder Führungsschiene jeweils einen Bremsbalken mit zu der Führungsschiene hin gerichteten Reibbelägen haben und wenn die Fahrzeuge jeweils eine Bremsbetätigung zum Verschieben des Bremsbalkens mit den Reibbelägen von oben her gegen die Führungsschiene aufweisen. Eine solche Bremse wirkt nicht, wie bei Fahrzeugen allgemein üblich, über die Tragräder, so dass man beim Abbremsen nicht auf die geringe Reibung zwischen den Tragrädern und den Fahrschienen angewiesen ist.The means for braking the individual vehicles are designed to be particularly simple and effective if the vehicles have a brake bar on each side above each guide rail with friction linings facing the guide rail and if the vehicles each have a brake actuation for displacing the brake bar with the friction linings from above forth against the guide rail. Such a brake does not act, as is generally the case with vehicles, via the carrying wheels, so that one does not rely on the low friction when braking between the carrying wheels and the rails.
Konstruktiv besonders einfach ist die Bremse gestaltet, wenn gemäß einer anderen Weiterbildung der Erfindung die Bremsbalken mittels Lenker am Fahrgestell des Fahrzeugs pendelnd befestigt sind und wenn die Bremsbetätigung einen u-förmigen, mit seiner Basis schwenkbar am Fahrgestell gelagerten Bremsbügel hat, dessen freie, nach oben ragende Schenkel jeweils einen Bremshebel bilden und welcher an der den Bremshebeln entgegengesetzten Seite jeweils einen an einem Bremsbalken angelenkten Lenkerarm aufweist.The brake is structurally particularly simple if, according to another development of the invention, the brake bars are pivotally attached to the chassis of the vehicle by means of a handlebar and if the brake actuation has a U-shaped brake bracket with its base pivotably mounted on the chassis, the free, upward projecting legs each form a brake lever and which on the opposite side of the brake levers each has a link arm articulated on a brake beam.
Die Bremse wirkt wie eine Zange, indem ihre Bremsbacken die Führungsschiene von oben und unten wie bei einer Scheibenbremse umgreifen und zwischen sich einspannen, wenn gemäß einer anderen Weiterbildung der Erfindung die Hebelverhältnisse bei der Bremsbetätigung zum Abheben des Fahrzeugs von den Fahrschienen und zum Anpressen der horizontalen Stege der Führungsausleger von unten her gegen die Führungsschiene bemessen sind. Durch unterschiedliche Reibbeläge in den horizontalen Stegen lassen sich sehr gute Nassbremseigenschaften erzielen.The brake acts like a pair of pliers in that its brake shoes grip the guide rail from above and below like a disc brake and clamp between them if, according to another development of the invention, the lever ratios when the brake is actuated to lift the vehicle off the rails and to press the horizontal Webs of the guide arm are dimensioned from below against the guide rail. Very good wet braking properties can be achieved through different friction linings in the horizontal webs.
Weil gemäß der Erfindung die Fahrschienen auf StändernBecause according to the invention the rails on stands
• stehen, können sie mit beträchtlicher Höhe über dem Erdboden verlaufen. Das kann bei nicht ausreichend im Fahrzeug durch Anschnallgurte gesicherten Personen insbesondere in Kurven zu einem Unfallrisiko führen, falls solche Personen aus dem Fahrzeug herausfallen. Ein Herunterfallen aus einer gefährlichen Höhe lässt sich zuverlässig und mit einfachen Mitteln ausschließen, wenn gemäß einer anderen Weiterbildung der Erfindung an den Tragkörpern zur Befestigung von entlang des Fahrweges verlaufenden Fangnetzen C-förmige Bügel derart angebracht sind, dass die Basis der Bügel sich horizontal erstreckt und an dem jeweiligen Tragkörper anliegt und die offene Seite des C's sich oberhalb der Tragschienen befindet.• stand, they can run at a considerable height above the ground. This can lead to an accident risk if people are not sufficiently secured in the vehicle by means of seat belts, especially in curves, if such people fall out of the vehicle. Falling from a dangerous height can be reliably and easily excluded if, according to another development of the invention, C-shaped brackets are attached to the supporting bodies for fastening safety nets running along the route in such a way that the base of the bracket extends horizontally and lies against the respective support body and the open side of the C is above the support rails.
Bei Störungen kann man auch dort einen Wagen gefahrlos verlassen, wo die Fahrschienen relativ hoch über dem Erdboden verlaufen, wenn die C-förmigen Bügel zur Abstützung eines entlang des Fahrweges verlaufenden Laufsteges ausgebildet sind.In the event of malfunctions, you can safely leave a car where the rails run relatively high above the ground if the C-shaped brackets are designed to support a walkway running along the path.
Zu hohe Fahrgeschwindigkeiten der Fahrzeuge lassen sich zwangsweise ausschließen, indem die Tragräder jeweils mit einer durch Fliehkraft bei einer festgelegten Drehzahl der Tragräder zwangsläufig sich betätigenden Trommelbremse ausgestattet sind.Excessively high vehicle speeds can be forcibly excluded by equipping the carrying wheels with a drum brake which is inevitably activated by centrifugal force at a fixed speed of the carrying wheels.
Die Fahrzeuge bewegen sich auch in engen Kurven sehr rei- bungsverlustarm, wenn die Tragräder der Vorderachse jeweils um eine in Fahrtrichtung vor den Tragrädern angeordnete, vertikale Achse begrenzt pendelnd am jeweiligen Fahrzeug gelagert sind.The vehicles move with very little friction loss even in tight bends if the supporting wheels of the front axle are mounted on the respective vehicle to a limited extent in an oscillating manner about a vertical axis arranged in front of the supporting wheels in the direction of travel.
Diese pendelnde Aufhängung der vorderen Tragräder ist konstruktiv besonders einfach zu verwirklichen, wenn gemäß einer anderen Weiterbildung der Erfindung die Tragräder der Vorderachse jeweils in einer Gabel gelagert sind, welche vor dem Tragrad in einer Lagertasche um die vertikale Achse begrenzt schwenkbar gehalten ist.This oscillating suspension of the front support wheels is structurally particularly simple to implement if, according to another development of the invention, the support wheels of the front axle are each mounted in a fork, which is held in a bearing pocket in front of the support wheel to a limited extent about the vertical axis.
Eine andere Weiterbildung der Erfindung besteht darin, dass die einzelnen Fahrzeuge jeweils eine selbstverstärkende Bremse aufweisen. Hierdurch lassen sich auch mit relativ geringen Kräften am Bremshebel und bei nassen Führungsschienen ausreichend hohe Verzögerungswerte erreichen. Die gewünschte Selbstverstärkung lässt sich dadurch mit geringem konstruktiven Aufwand verwirklichen, dass die Bremsbalken durch in Fahrtrichtung gesehen schräg nach vorn ausgerichtete Lenker mit dem Fahrgestell des Wagens verbunden sind. Hierdurch wirkt die einsetzende Bremskraft auch in Zustellrichtung der Bremsbeläge und erleichtert somit das Bremsen, was insbesondere bei nassen Führungsschienen vorteilhaft ist.Another development of the invention is that the individual vehicles each have a self-energizing brake. As a result, sufficiently high deceleration values can be achieved even with relatively low forces on the brake lever and with wet guide rails. The desired self-reinforcement can be achieved with little design effort that the brake beams are connected to the chassis of the car by the handlebars which are oriented obliquely forward in the direction of travel. As a result, the braking force that is applied also acts in the feed direction of the brake pads and thus facilitates braking, which is particularly advantageous in the case of wet guide rails.
Die Bremseinrichtungen der Wagen der erfindungsgemäßen Freizeitsportanlage sollten so gestaltet sein, dass ein fahrerloser Wagen selbsttätig bremst. Das lässt sich auf einfache Weise verwirklichen, wenn gemäß einer anderen Weiterbildung der Erfindung der Bremshebel mit einer nach vorn gekrümmten Führung versehen ist und in dieser Führung eine Feder angreift, welche mit ihrem anderen Ende am Fahrgestell befestigt ist und dadurch den Bremshebel in Bremsrichtung vorspannt. Durch diese Gestaltung verkürzt sich beim Lösen der Bremse der Hebelarm, mit welchem die Feder am Bremshebel angreift, so dass zum Lösen keine unerwünscht hohen Kräfte erforderlich werden.The braking devices of the wagons of the leisure sports facility according to the invention should be designed so that a driverless wagon brakes automatically. This can be achieved in a simple manner if, according to another development of the invention, the brake lever is provided with a forwardly curved guide and in this guide a spring engages which is attached to the chassis with its other end and thereby prestresses the brake lever in the braking direction. This design shortens the lever arm with which the spring acts on the brake lever when the brake is released, so that no undesirably high forces are required for the release.

An den Tragkörpern 2 ist ein C-förmiger Bügel 27 derart befestigt, dass seine Öffnung nach oben weist und seine Basis sich horizontal erstreckt. Dieser Bügel 27 dient der Befestigung eines nicht gezeigten Fangnetzes. Weiterhin liegt auf ihm ein Laufsteg 28 auf, der durch einfache Bohlen gebildet sein kann.A C-shaped bracket 27 is fastened to the supporting bodies 2 in such a way that its opening points upwards and its base extends horizontally. This bracket 27 is used to attach a safety net, not shown. Furthermore, there is a catwalk 28 on it, which can be formed by simple planks.
Die Figur 2 zeigt gegenüber Figur 1 im Maßstab vergrößert den Tragkörper 2 mit den Fahrschienen 3 , 4 und den Führungsschienen 5, 6. Von einem Fahrzeug 13 erkennt man ein Fahrgestell 14 und zwei Tragräder 15, 16, deren Achsen 17, 18 zueinander V-förmig ausgerichtet sind, so dass sich die Tragräder 15, 16 schräg von innen auf den Fahrschienen 3, 4 abstützen. Vom Fahrgestell 14 aus ragt an jeder Fahrzeugseite vorn und hinten jeweils ein Führungsausleger 19, 20 innenseitig an der Führungsschiene 5, 6 vorbei nach unten, welcher jeweils mit einem horizontalen Schenkel 21 unter die Führungsschiene 5, 6 greift. Oberhalb der beiden Führungsschienen 5, 6 erkennt man jeweils einen Reibbelag 22, 23, welcher auf noch zu erläuternde Weise gegen die Führungsschienen 5, 6 bewegt werden kann, um das Fahrzeug 13 abzubremsen. Zum automatischen Abbremsen des Fahrzeugs 13 bei zu hohen Fahrgeschwindigkeiten sind die Tragräder 15, 16 jeweils mit einer durch Fliehkraft zwangsläufig betätigbaren Trommelbremse 33 ausgestattet.FIG. 2 shows, compared to FIG. 1, on an enlarged scale, the support body 2 with the travel rails 3, 4 and the guide rails 5, 6. From a vehicle 13 one recognizes a chassis 14 and two support wheels 15, 16, the axes 17, 18 of which are mutually V- are aligned so that the support wheels 15, 16 are supported obliquely from the inside on the rails 3, 4. From the chassis 14 protrudes on each side of the vehicle, front and rear, a guide arm 19, 20 on the inside past the guide rail 5, 6 downward, which engages with a horizontal leg 21 under the guide rail 5, 6. Above the two guide rails 5, 6, one can see a friction lining 22, 23, which can be moved against the guide rails 5, 6 in a manner yet to be explained, in order to brake the vehicle 13. For the automatic braking of the vehicle 13 at excessively high driving speeds, the carrying wheels 15, 16 are each equipped with a drum brake 33 which can be actuated by centrifugal force.
Die Figur 3 lässt unterhalb des Fahrgestells 14 des Fahrzeugs 13 einen Bremsbalken 24 erkennen, welcher die Reibbeläge 22, 22a trägt. Dieser Bremsbalken 24 ist mit Lenkern 25, 26 pendelnd am Fahrgestell 14 befestigt und kann mittels einer Bremsbetätigung 29 bewegt werden. Hierzu hat die Bremsbetätigung 29 an jeder Fahrzeugseite einen um eine quer zu dem Fahrzeug 13 verlaufende Achse 32 schwenkbaren Bremshebel 30, welcher ebenfalls mit einem Lenkerarm 31 an dem Bremsbalken 24 angelenkt ist. Verschwenkt man den Bremshebel 30 aus der in Figur 3 gezeigten Stellung nach vorn, dann verschwenkt sich der Lenkerarm 31 im Uhrzeigersinn und hebt dadurch den Bremsbalken 24 an, was zu einem Freikommen der Reibbeläge 22, 22a von den in den Figuren 1 und 2 gezeigten Führungsschienen 5, 6 führt. In der in Figur 3 gezeigten Bremsstellung ist der Bremsbalken 24 so weit nach unten verschoben, dass die Reibbeläge 22, 23 von oben her auf der in Figur 2 gezeigten Führungsschiene 5 aufsitzen und die Stege 21 der Führungsausleger 19 von unten her gegen die Führungsschiene 5 pressen, so dass diese zum Bremsen wie von einer Zange eingeklemmt wird. Die Figur 4 verdeutlicht zusätzlich die Gestaltung des Fahrzeugs 13. Zu erkennen ist, dass die BremsbetätigungFIG. 3 shows a brake beam 24 below the chassis 14 of the vehicle 13, which carries the friction linings 22, 22a. This brake beam 24 is pivotally attached to the chassis 14 with links 25, 26 and can be moved by means of a brake actuation 29. For this purpose, the brake actuation 29 has on each side of the vehicle a brake lever 30 which can be pivoted about an axis 32 extending transversely to the vehicle 13 and which is likewise articulated on the brake beam 24 with a control arm 31. If the brake lever 30 is pivoted forward from the position shown in FIG. 3, the link arm 31 pivots clockwise and thereby raises the brake beam 24, which leads to the friction linings 22, 22a being released from the guide rails shown in FIGS. 1 and 2 5, 6 leads. In the braking position shown in FIG. 3, the brake beam 24 is displaced so far down that the friction linings 22, 23 are seated on the guide rail 5 shown in FIG. 2 and the webs 21 of the guide arms 19 press against the guide rail 5 from below , so that it is clamped like a pair of pliers for braking. FIG. 4 also illustrates the design of the vehicle 13. It can be seen that the brake actuation
29 bügeiförmig ausgebildet ist und an jeder Fahrzeugseite einen Bremshebel 30, 30a hat. Weiterhin sieht man unter anderem die Tragräder 15, 16 einer Hinterachse 24 und Tragräder 15a sowie 16a einer Vorderachse 35 des Fahrzeugs 13.29 is bow-shaped and has a brake lever 30, 30a on each side of the vehicle. Furthermore, one can see, among other things, the support wheels 15, 16 of a rear axle 24 and support wheels 15a and 16a of a front axle 35 of the vehicle 13.
Die Figur 5 zeigt, dass die Vorderachse 35 an ihren beiden äußeren Seiten jeweils eine Lagertasche 37, 38 hat, in welcher jeweils um eine vertikale Achse 39 schwenkbar eine Gabel 40 begrenzt schwenkbar gelagert ist, die das Tragrad 16 bzw. 15a lagert.FIG. 5 shows that the front axle 35 has on each of its two outer sides a bearing pocket 37, 38, in each of which a fork 40 is pivotally pivotably supported about a vertical axis 39 and supports the carrying wheel 16 or 15a.
Die Figur 6 zeigt das Fahrgestell 14 eines Fahrzeugs 13 mit einem Bremsbalken 24, welcher durch schräg nach vorn ausgerichtete Lenker 41, 42 mit dem Fahrgestell 14 verbunden ist. Der Bremshebel 30 ist um einen Drehpunkt 47 des Fahrgestells 14 schwenkbar und durch eine Koppel 43 mit dem Lenker 42 verbunden. Schwenkt man den BremshebelFIG. 6 shows the chassis 14 of a vehicle 13 with a brake beam 24 which is connected to the chassis 14 by links 41, 42 oriented obliquely towards the front. The brake lever 30 is pivotable about a pivot point 47 of the chassis 14 and connected to the handlebar 42 by a coupling 43. If you swivel the brake lever
30 entgegengesetzt zum Uhrzeigersinn, dann verschwenkt die Koppel 43 den Lenker 42 im Uhrzeigersinn, wodurch der Bremsbalken 24 sich parallel zu sich selbst gegen die Führungsschiene 5 bewegt und dadurch die Bremsung eintritt.30 counterclockwise, then the coupling 43 pivots the handlebar 42 clockwise, whereby the brake beam 24 moves parallel to itself against the guide rail 5 and thereby braking occurs.
Die Betätigung des jeweiligen Bremsbalkens 24 durch den Bremshebel 30 kann auch auf andere Weise erfolgen, beispielsweise dadurch, dass eine Koppel vom Bremshebel 30 unmittelbar zu dem Bremsbalken 24 führt.The actuation of the respective brake beam 24 by the brake lever 30 can also take place in another way, for example in that a coupling from the brake lever 30 leads directly to the brake beam 24.
Wichtig ist, dass die Lenker 41, 42 schräg nach vorn weisen, wobei sich ein Winkel von maximal 45° zum Fahrgestell als erforderlich herausgestellt hat. Durch diesen schräg nach vorn gerichteten Verlauf der Lenker 41, 42 tritt ein Selbstverstärkungseffekt ein. Bewegt sich das Fahrzeug 13 nach rechts und wird gebremst, dann hat das entstehende Reibmoment die Tendenz, den Bremsbalken 24 mit zunehmender Kraft auf die Führungsschiene 5 zu drücken.It is important that the links 41, 42 point diagonally forward, an angle of at most 45 ° to the chassis having been found to be necessary. This diagonally forward course of the links 41, 42 results in a self-reinforcing effect. Does that move Vehicle 13 to the right and is braked, then the resulting friction torque tends to press the brake beam 24 with increasing force onto the guide rail 5.
Die Figur 6 zeigt weiterhin, dass der Bremshebel 30 durch eine Feder 44 in Bremsstellung vorgespannt wird. Diese Feder 44 ist mit einem Ende am Fahrgestell 14 befestigt und stützt sich mit ihrem anderen Ende über eine Rolle 45 auf einer Führung 46 des Bremshebels 30 ab. Diese Führung 46 ist starr am Bremshebel 30 angebracht und verläuft bogenförmig gekrümmt, wobei der Krümmungsmittelpunkt in Fahrtrichtung gesehen vor dem Bremshebel 30 liegt und der Bogen durch den Drehpunkt des Bremshebels 30 führt. Durch diese Gestaltung der Führung 46 ergibt es sich, dass der Angriffspunkt der Feder 44 am Bremshebel 30 um so weiter in Richtung des Drehpunktes 47 wandert, je mehr man den Bremshebel 30 nach vorn drückt. Die Feder 44 vermag also mit einem maximalen Hebelarm am Bremshebel 30 anzugreifen, wenn man den Bremshebel 30 loslässt, wirkt jedoch in dem Maße geringer auf den Bremshebel 30 ein, wie man den Bremshebel 30 nach vorn schwenkt, weil der Angriffspunkt der Feder 44 dabei bis zum Drehpunkt 47 des Bremshebels 30 wandert. Deshalb benötigt man keine hohen Kräfte, um die Bremseinrichtung in Lösestellung zu halten. FIG. 6 also shows that the brake lever 30 is prestressed in the braking position by a spring 44. This spring 44 is attached at one end to the chassis 14 and is supported at its other end via a roller 45 on a guide 46 of the brake lever 30. This guide 46 is rigidly attached to the brake lever 30 and has an arcuate curve, the center of curvature lying in the direction of travel lying in front of the brake lever 30 and the arc leading through the pivot point of the brake lever 30. This design of the guide 46 results in the point of application of the spring 44 on the brake lever 30 moving in the direction of the pivot point 47 the more the brake lever 30 is pressed forward. The spring 44 can thus attack the brake lever 30 with a maximum lever arm when the brake lever 30 is released, but acts less on the brake lever 30 to the extent that the brake lever 30 is pivoted forwards because the point of application of the spring 44 to migrates to the pivot point 47 of the brake lever 30. Therefore, no high forces are required to hold the brake device in the release position.
