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
,
44
,
19
. In addition, the number of the pulling and tensioning cables
43
,
44
,
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.
