Description




FIELD OF THE INVENTION




The present invention pertains to an amusement facility with one or more vehicles and a catapult drive for the vehicles.




BACKGROUND OF THE INVENTION




Such an amusement facility with a catapult drive has been known from FR-A 366 258. A vehicle is moved here at a high velocity along a track curved in space and shall return into the starting position at the end in free flight. The catapult drive comprises a plurality of springs, which are placed in pipes and are connected to a carrier.




A similar catapult drive with drive springs is shown in DE-C 177 794. The catapult drive acts on a rail-borne vehicle and moves same upward along an oblique ramp. The vehicle returns into the starting position on the same path. The springs are tensioned by means of a chain drive. In addition, a braking means is also present, which works against the springs at the beginning of the acceleration section and diminishes the acceleration acting on the passengers.




WO 98/45007 likewise pertains to an amusement facility, in which passenger carriers are moved to and fro on a rail track. Besides a conventional chain drive, a catapult drive, which is not described specifically and is also not shown, may be used as the drive.




Another amusement facility with a catapult drive has been known from DE-A 27 03 833. The catapult drive comprises a cable or chain guided endlessly with a connected accelerating carriage for the passenger carrier and is operated with a falling weight as a pushing drive. As an alternative to the falling weight, a stationary linear pushing drive, which may be designed as a linear motor or as a hydraulic lifting cylinder with a reduced ratio, may be used in the area of the starting section.




Finally, another catapult of the type of an ejection seat, in which the seat is pivoted by means of a pivoting lever, has been known from DE-A 44 25 107. The drive is not described specifically.




Another amusement facility in the manner of a roller coaster has been known from DE-A 28 32 991 and DE-U 298 22 644. Immediately after leaving the boarding point, the vehicles are towed with a drive means, which is designed as an endless chain drive, to the highest elevation of the roller coaster over an ascending section and are released there. The chain drive is relatively slow and it pulls the vehicle leisurely upward.




In chain mechanisms, the towing force is transmitted via a sprocket wheel engaging the chain in a positive-locking manner. The polygon effect generated in the process leads to high stresses and to noise. In addition, lubrication of the chain is necessary, which leads to problems with dripping and to difficulties in disposal. Due to the heavy weight, the field of use is limited to short distances and to low velocities in the range of up to about 5 m/sec. The endless chain drives have carriers, which engage the vehicles of the amusement facility.




SUMMARY AND OBJECTS OF THE INVENTION




The object of the present invention is to improve the prior-art amusement facility.




This object is accomplished by the present invention with an amusement facility with one or more vehicles and a drive means for the vehicles wherein the drive means is designed as a catapult drive. The catapult drive has one or more hydromotors.




The drive means is designed in the amusement facility as a catapult drive, which drives one or more vehicles at a high acceleration and velocity from standing or slow travel and launches them preferably into a free travel section. This high initial acceleration and velocity offers a new attraction and experience for roller coasters, but also for other types of rides.




Extremely high driving forces or driving torques can thus be transmitted and high accelerations can be reached, so that the vehicles can reach velocities in excess of 50 m/sec and accelerations exceeding 2 g within a few seconds. The moving masses of the vehicle and the passengers may vary between a few hundred kg and several tons.




The catapult drive is suitable for all types of amusement facilities. Special advantages arise for roller coasters and other similar types of rides.




Hydromotors are used as drive motors. They have the advantage that they are able to make available the enormous accelerating energy of several MW, which is necessary for a short time. The accelerating energy can, furthermore, be buffered between the starts taking place at regular intervals by means of storage units. Contrary to direct drives, the installed power can thus be drastically reduced. In addition, the hydromotor has the advantage of having an especially small size and small inertia of masses. Moreover, it is far superior to a pneumatic drive in terms of efficiency, energy loss and noise emission.




The catapult drive may be designed as an endless drive or as a winding or winch drive. A winding drive has some special advantages. Due to the positive-locking connection of the drive or winding drum to the pulling means, friction effects and friction dependencies can be eliminated. The wrapping angle and the pretensioning forces can be lower than in the case of a friction drive, and the pulling means, preferably one or more pulling cables, are also spared more and last longer. A multiple cable arrangement makes it possible for the individual pulling cables to have a smaller cross section. This results in a smaller drum diameter, which further increases the effectiveness of the catapult drive.




It is, furthermore, recommended that a carrying means and especially a towing car, which engages the vehicle to be accelerated with a movable carrier hook, be fastened to the pulling means. The preferred embodiment offers special advantages in terms of a simple design and operational safety.




The pulling means may have different designs. Instead of a chain, it is possible to use a cable or belt, which are better suited for the extremely high accelerations and velocities as well as the loads resulting therefrom. A multiple cable arrangement or a broad-area pulling means, which preferably comprises a plurality of cable strands located in parallel next to one another and are optionally connected to one another, or a belt, is advantageous, but another design is also possible as an alternative. The pulling means comprises a material suitable for the high load.




The pulling means has the advantage over a chain in that the need for lubrication can be eliminated, as a result of which the towing forces can be transmitted with a correspondingly higher coefficient of friction in the case of a friction drive. This leads, furthermore, to a substantial reduction in the pretensioning force. In addition, the pulling means can pass over one or more drive and deflecting rollers without a substantial reduction of the service life.




The pulling means has, furthermore, the advantage of having a lower price, lower noise emission, lower weight as well as lower inertia of masses. The handling and maintenance are facilitated and improved. Favorable effects are also obtained for disposal and environmental friendliness. Furthermore, the small possible bending radius, the high fatigue strength under reversed bending stresses and the high reliability of operation are advantages as well.




The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to the drawings in particular,

FIG. 1

shows an amusement facility


1


, which is designed as a ride, e.g., as a roller coaster. It comprises a rail-like guide


3


for one or more vehicles


2


, which are set into motion by means of a drive means


13


. The drive means


13


drives the vehicles


2


along an acceleration section


11


, accelerates them in the process to the desired initial velocity, and releases them at the end of the acceleration section


11


.

FIGS. 2 and 3

show the acceleration section


11


and the drive means


13


located there in a simplified and broken-away view.




The vehicles


2


separated from the drive means


13


will then move on a freely selected free travel section


12


based on their kinetic energy. The travel section may be finite or endless. It may have elevations, valleys, curves, slopes, loopings, plunge sections or any other layout. In the embodiment being shown, the vehicles


2


are first catapulted by the drive means


13


to a tower-like elevation


6


in a steep ascending section after a start-up section, and the vehicles return from the zenith of the elevation


6


to their starting point in a slope section


7


with subsequent travel sections


8


in a roller coaster travel. As an alternative, the vehicles


2


may also be catapulted in a looping or another path section.




The drive means


13


is present as a single drive means in the preferred embodiment. However, multiple drive means may also be present in larger facilities and ensure the intermediate acceleration of the cars. The amusement facility


1


also has, furthermore, one or more braking sections


9


. It has, moreover, a boarding area


10


, which is optionally also preceded by a resting or waiting section. The amusement facility


1


may also have a plurality of elevations. It may have any desired layout. For clarity's sake, only the acceleration section


11


of the amusement facility


1


with the drive means broken off and shortened is shown in

FIGS. 4 and 5

.




In the embodiment being shown, the vehicles


2


move on a guide


3


along the travel section, which is designed, e.g., as a closed track. The travel section is designed as a rail structure and has, e.g., a suitable cross-sectional profile with a suitable number of running rails and optionally also support rails. The vehicles


2


roll with a suitable chassis


4


on the guide


3


. The guide


3


may otherwise also have any other desired design, e.g., it may also be designed as a monorail guide for vehicles


2


suspended overhead.




The drive means


13


is designed in the preferred embodiment being shown as a highly dynamic catapult or throwing drive


22


, which accelerates the cars to a launch velocity of about 150 km/hour or more within a few seconds. In the embodiment being shown, the acceleration or drive section


11


is located at a spaced location in front of the first elevation


6


and is located in an essentially horizontal or preferably only relatively weakly sloping starting area.




The drive means


13


has a reversible design in the embodiment being shown and operates intermittently. It drives the vehicles


2


by pushing or pulling in the direction of travel


5


in one direction and detachably and launches them. After the separation of the vehicles


2


, it returns into its starting position at the point of boarding


10


.




The drive means


13


has a pulling means


20


with a carrying means


14


for the vehicles


2


. The catapult drive


22


drives the pulling means


20


with one or more motors


24


. The pulling means


20


and optionally a tensioning cable


19


are pretensioned by means of a cable tensioner


23


and their strands are held permanently under tensile stress.




FIG.


4


and

FIGS. 5 and 6

show two different embodiments of the catapult drive


22


. It is designed as an endless drive in FIG.


4


and as a winding drive in

FIGS. 5 and 6

.




In the variant according to

FIG. 4

, the pulling means


20


is led in a closed loop along the acceleration section


11


and is fastened with its two ends to the carrying means


14


. The pulling means


20


is led in a single loop over two end-side driving and deflecting rollers


25


,


26


. As an alternative, a plurality of driving and deflecting rollers


25


,


26


may be present as well. The catapult drive


22


is designed, e.g., as a friction drive.




In the embodiment according to

FIG. 4

, the broad-area pulling means


20


is designed as an elastic multiple cable array


21


, which is formed by a plurality of preferably single-layer, thin cable strands or strands located in parallel next to one another. The cable strands may be connected to one another to form a one-part pulling means


20


. As an alternative, the cable strands may also be located loosely next to one another. The cable strands may consist of steel or a plastic with high load-bearing capacity and do not need to be lubricated. They may also have a suitable jacketing. The ratio of the thickness of the cable or strand to the width of the pulling means


20


may be preferably between about 1:10 and 1:30 or higher to obtain the desired broad area. The cable strands may run over guide means of a corresponding shape with grooves or the like.




In an alternative embodiment, not shown, the pulling means


20


may also comprise a plurality of belts or other similar strands, running in parallel. In another variant, the pulling means


20


may be designed as a belt, which has a high tensile strength in conjunction with a high fatigue strength under reversed bending stresses and a surface that is favorable with respect to friction. In one variant, the belt


21


may also have a transversely and/or longitudinally profiled surface, e.g., in the form of a toothed belt. Furthermore, it is possible to arrange a plurality of belts next to one another.




As is indicated in

FIG. 3

, the drive means


13


is integrated within the running rail


3


and is located within the rail structure. The inner area of the latter and the drive means


13


are accessible from the outside. The motor


24


of the catapult drive


22


is located at the front end of the acceleration section


11


in the direction of travel


5


, and the cable tensioner


23


is located at the rear end. This arrangement may also be reversed as an alternative or be designed differently in another way. The pulling means


20


extends along and preferably extensively within the running rail


3


.




The carrying means


14


may have different designs. Because of the ability of the pulling means


20


, it is provided with a guide


16


of its own, which is located within the running rail


3


. It comprises, e.g., a centrally arranged rail with two C profiles, which face each other with their openings and are arranged at laterally spaced locations from the center. The guide


16


extends essentially over the length of the acceleration section


11


. The carrying means


14


comprises a towing car


15


, which can travel in the guide


16


and to which the ends of the pulling means


20


are fastened. The towing car


15


has a suitable carrying means


17


, which engages the vehicle


2


in a positive-locking or frictionally engaged manner and transmits the driving forces generated by the catapult drive


22


to the vehicle


2


, while pulling or pushing the vehicle


2


.




In the preferred embodiment, the carrying means


17


comprises a movable catch, which can be pivoted up and down by means of a pivot bearing. In the raised docking position, which is shown in

FIG. 4

, the catch


17


engages the vehicle


2


in a positive-locking manner. In the lowered inoperative position, the vehicle


2


can run over the catch


17


. The raising and lowering of the catch


17


can be performed in any desired, suitable manner. A suitable connecting link, which extends under the catch


17


during the reverse travel of the vehicle


2


and raises same into the docking position, may be present at the vehicle


2


. The catch


17


drops back automatically into the inoperative position under the force of gravity at the end of the acceleration section


11


after the vehicle


2


has been launched.




The carrying means


14


may have, moreover, a suitable braking means


18


, which actively brakes it at the end of the acceleration section


11


. This braking means


18


may have any desired, suitable design. As an alternative or in addition, braking may also be performed by means of the catapult drive


22


.




At the end of the acceleration section


11


, the accelerated vehicle


2


becomes detached from the braked carrying means


14


, which will then stop and subsequently move slowly back into the starting position at the beginning of the acceleration section


11


. The catch


17


is now lowered into the inoperative position. After passing over the travel section, the vehicle


2


returns into the starting position, running over the towing car


15


standing ready. The vehicle


2


is then moved back into the definitive start position by a return means, not shown, e.g., an array of a plurality of friction wheels, and the vehicle extends now under the catch


17


with its connecting link and raises it into the docking position. There is a positive-locking connection, which is loadable in the direction of travel


5


, between the carrying means


14


and the vehicle


2


in this position. The friction wheels can then again be deactivated and removed from the range of travel of the vehicle


2


. A plurality of vehicles


2


may also be under way in different track sections at the same time on the amusement facility


1


.




The cable tensioner


23


is schematically shown in FIG.


4


. In the preferred embodiment, it comprises one or more suitable tensioning drives


30


, which move the deflecting roller


26


. The tensioning drive


30


applies a pulling and tensioning force on the belt loop via the deflecting roller


26


and tightens both strands of the pulling means


20


. The deflecting roller


26


moves opposite the direction of travel


5


for tensioning.




The catapult drive


22


is accommodated in a compact housing inside the running rail


3


. It has at least one drive roller


25


and at least one motor


24


. In the exemplary embodiment of a highly dynamic hydromotor shown, one drive roller


25


is present, to which one or more hydromotors


24


can be attached on both sides via a suitable transmission arrangement not shown and they together drive the drive roller


25


. Pressure is admitted to the hydromotors


24


from a hydraulic supply


31


.




The above-described catapult or hydraulic drive


22


and the hydraulic supply


31


can also be used successfully for other types of towing or travel drives as well as for other towing means. The hydraulic supply


31


offers an especially dynamic and high power in conjunction with the multiple arrangement of hydromotors


24


.




The hydraulic supply


31


has at least one hydraulic storage unit


32


, which is designed as a piston-type storage unit in the embodiment being shown. As an alternative, it may also have any other design, e.g., it may be a bubble storage unit or a spring-type storage unit. The separating piston


36


moves axially to and fro in the storage or cylinder space and separates the hydraulic fluid


33


, which is preferably a hydraulic oil, and a compressible storage fluid


34


, e.g., a gas, preferably nitrogen, from one another. The gas chamber in the hydraulic storage unit


32


is connected to an external gas pressure storage unit


35


, which is designed, e.g., as a battery of containers.




The hydraulic supply


31


also has, furthermore, at least one storage reservoir


38


, e.g., a tank, for the hydraulic fluid


33


. One or more pumps


39


, e.g., charge pumps, deliver the hydraulic fluid


33


from the storage reservoir


38


back into the hydraulic storage unit


32


. The hydraulic supply


31


also includes, furthermore, a network of lines


42


and valves


41


, via which the hydraulic fluid


33


is sent to the hydromotor or hydromotors


24


.




For using the hydraulic supply


31


, the hydraulic storage unit


32


is filled with the hydraulic fluid


33


by means of one or more pumps


39


, the stored fluid


34


is greatly compressed by means of the separating piston


36


and pre-pressurized. The connection lines to the hydromotor or hydromotors


24


are closed by the valves


41


at this point in time. To actuate the catapult drive


22


, the lines


42


to the hydromotor or hydromotors


24


are opened. The pre-pressurized stored fluid


34


expands and expels the hydraulic fluid


33


from the hydraulic storage unit


32


to the hydromotor or hydromotors


24


by means of the separating piston


36


, and the hydromotor or hydromotors


24


, being rotating drives with blade wheels or other similar guide organs, convert the flow energy into a rotary movement of the drive rollers


25


and drive the pulling means


20


in the direction of travel


5


with a strong force and acceleration. After flowing through the hydromotors


24


, the hydraulic fluid


33


flows back into the storage reservoir


38


.




As soon as the gas pressure of the stored fluid


34


has dropped to a predetermined value or the vehicle


2


has reached a desired velocity of travel, which is measured and signaled by a suitable measuring means (not shown), e.g., at the running rail


3


or at the hydromotor or hydromotors


24


, the catapult drive


22


is switched over to idle. The vehicle


2


is at the end of the acceleration section


11


at this stage. The carrying means


14


is then braked by the braking means


18


together with the connected pulling means


20


and the hydromotor or hydromotors


24


. The vehicle


2


now becomes detached from the carrying means


14


and continues to move on the free travel section


12


because of its preserved kinetic energy.




The catapult drive


22


is then switched over again, and hydromotors


24


driven in the opposite direction move the pulling means


20


with the towing car


15


back into the starting position at the boarding point


10


.

FIG. 5

shows a reversing cycle


40


, which is used for this, with a nonreturn valve


37


in the line between the hydromotors


24


and the tank


38


. The hydraulic storage unit


32


is again pressurized at the end of the return travel of the catapult drive


22


and is ready for the next ride.





FIGS. 5 and 6

show a variant of the catapult drive


22


, which is designed as a winding drive or cable winch drive. The pulling means


20


is again designed as a multiple cable array


21


and comprises, e.g., two pulling cables


43


,


44


, which are fastened to the front side of the catch car


15


in the direction of travel


5


. The two pulling cables


43


,


44


are attached and wound on a winding drum or cable drum


27


. The cable drum


27


has an essentially horizontal axis of rotation and is driven by one or more hydromotors


24


in a reversing manner. Two separate winding areas


28


,


29


, which are located at spaced locations from one another, are present here at the end areas of the cable drum


27


for the correspondingly spread-apart pulling cables


43


,


44


. The winding areas


28


,


29


have a suitable groove or cable guide


46


,


47


, e.g., on the jacket of the drum, for accurately placing the pulling cables


43


,


44


. Helical groove guides


46


,


47


, one of which,


46


, is left-handed and the other,


47


, is right-handed in the driving direction shown in

FIG. 6

, are present in the embodiment being shown. The spread-apart pulling cables


43


,


44


are wound up as a result from the outer sides toward the center during the rotation of the drum in the driving direction.




The catapult drive


22


also has, furthermore, a tensioning cable


19


in this embodiment, which is attached on the rear side of the catch car


15


. The tensioning cable


19


is led over the above-mentioned spaced-apart deflecting roller


26


and back under and through the catch car


15


to the cable drum


27


and is likewise attached with the other end to the cable drum


27


and wound up. The direction of winding of the tensioning cable


19


is opposite the winding direction of the pulling cables


43


,


44


.




The tensioning cable


19


has a winding area


45


of its own with a groove guide


48


on the cable drum


27


, which is located between the winding areas


28


,


29


of the pulling cables


43


,


44


. The groove guide


48


of the tensioning cable


19


has the same left-handed helical shape, size and pitch as the groove guide


46


of one pulling cable


43


, the two groove guides


46


,


48


passing over into one another. A common winding area


28


,


45


is obtained as a result for the two cables


19


,


43


.




The winding direction of the tensioning cable


19


is opposite the winding direction of the pulling cables


43


,


44


. When the pulling cables


43


,


44


, arriving on the top side of the drum, are wound up during the rotation of the drive of the cable drum


27


in the direction of travel


5


, the tensioning cable


19


is correspondingly wound off from the underside of the drum. Due to the opposite winding directions, the tensioning cable winding decreases to the same extent by which the pulling cable winding broadens and it yields space to the pulling cable winding. The movement is reversed in the reversing operation.




The hydromotor or hydromotors


24


and the cable drum


27


are likewise at the end of the acceleration section


11


that is the front end in the direction of travel


5


in this embodiment of the catapult drive


22


. The deflecting roller


26


is arranged on the other side at the rear end of the acceleration section


11


. In the start position of the vehicle


2


and of the catch car


15


, the pulling cables


43


,


44


are wound off completely or at least almost completely. The tensioning cable


19


is, by contrast, wound up completely or nearly completely. The catapult drive


22


will then rotate the cable drum


27


at a high velocity by means of the hydromotor or hydromotors


24


. As a result, the pulling cables


43


,


44


are wound up and they pull the catch car


15


in the direction of travel. At the same time, the tensioning cable


19


is wound off and is fed via the deflecting roller


26


corresponding to the movement of the car.




The catapult drive


22


is braked at the end of the drive or acceleration section


11


in the above-described manner and the hydromotor or hydromotors


24


are switched over to idle. During the subsequent reversing operation, the hydromotor or hydromotors


24


rotate the cable drum


27


in the opposite direction and the tensioning cable


19


is again wound up and it pulls back the catch car


15


into the start position as a result. The pulling cables


43


,


44


wound off from the cable drum


27


are dragged at the same time by the catch car


15


. The cable tensioner


23


acting on the deflecting roller


26


always keeps the pulling and tensioning cables


43


,


44


,


19


under a predetermined tensile stress.




Various modifications of the embodiment shown are possible. On the one hand, the pulling means


20


may have any other desired, suitable design. Furthermore, the catapult drive


22


may have any other desired number and arrangement of driving and deflecting rollers


25


,


26


and motors


24


. In the endless drive according to

FIG. 4

, a toothed belt drive or the like with positive-locking power transmission is also possible instead of a friction drive with non-positive power transmission. The drive means


13


may also be designed as a continuous drive with a short acceleration phase and a subsequent, extensively constant velocity phase. In the design as a hydraulic drive, the hydromotors


24


may also be coupled with another type of hydraulic supply


31


.




In the exemplary embodiment of an endless drive shown in

FIG. 4

, the pulling means


20


is guided and driven in a loop. The catapult drive


22


and the movement of the pulling means are reversible and they alternatingly perform a forward movement and a reverse movement. However, the endless drive may also drive the pulling means


20


continuously and in a constant direction of movement in a variant which is not shown.




As an alternative, a plurality of cable drums


27


may be present in the winding drive according to

FIGS. 5 and 6

, and a separate winding drum


27


may also be provided for each pulling and tensioning cable


43

,


19


may be varied as desired and it may be lower or greater than in the exemplary embodiment being shown. The design embodiment and the arrangement of the cable guide


46


,


47


,


48


, which may comprise, e.g., upstream guide elements traveling along the drum during its rotation, are also variable. Other winding drives and winding elements may also be used instead of a winding or cable drum


27


with horizontal axis of rotation.




Furthermore, the connection between the pulling means


20


and the catapult drive


22


is also variable. The carrying means


14


is detachable in the embodiment shown and acts in one direction on the vehicle


2


. In one variant, which is not shown, it is possible to permanently connect the carrying means


14


to the vehicle


2


and to return the vehicle


2


into the starting position in the reversing operation together with the carrying means


14


. Such a design is suitable, e.g., for fall frames, in which the vehicle


2


is moved upward with the drive means


13


on a vertical or oblique frame and is then let fall after switching off the catapult drive


22


and is moved downward by its own weight. As an alternative, the catapult drive


22


may also act on the vehicle


2


in the reversing operation during the downward movement. In another variant, it is possible to do away with the additional carrying means


14


and to fasten the pulling means


20


to the vehicle


2


. There is direct drive by the catapult drive


22


in the reversing or endless operation in this case.




In addition, the amusement facility


1


may have any other desired, suitable design and have other types of vehicles and guides or sections for the vehicles.




While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
