[0001] The present invention relates to an attraction for amusement rides, such as a fairground
attraction or an amusement park attraction, comprising at least one tower from which
a main shaft extends, a pendulum arm rotatably mounted on the main shaft, first drive
means for moving the pendulum arm in a plane substantially perpendicularly of the
main shaft, and at least one passenger gondola mounted on an outer end of the pendulum
arm.
[0002] Such an attraction is known in the field and is marketed in several variants. The
known attraction swings the pendulum arm with passenger gondola high in the air, wherein
the passengers are subjected to high G-forces during the ride and at the highest point
experience a sensational feeling of weightlessness.
[0003] The present invention has for its object to add an additional sensation to an attraction
of the type stated in the preamble.
[0004] The attraction according to the invention has for this purpose the feature that the
pendulum arm comprises two parts which are pivotally connected to each other, wherein
a first part is mounted rotatably on the main shaft and wherein a second part is provided
with the passenger gondola on the outer end, wherein second drive means are provided
for moving the second part in a direction substantially perpendicularly of the plane
of movement.
[0005] The attraction according to the invention provides an additional degree of freedom
of movement which provides for a spectacular combination of pivoting movements and
offers the passengers a wonderful, unforgettable ride.
[0006] In a first preferred embodiment the second drive means are configured to move the
second part in two opposite directions, each running substantially perpendicularly
of the plane of movement. The attraction according to the first preferred embodiment
provides another additional degree of freedom of movement which provides for an even
more spectacular combination of pivoting movements and gives the passengers an intense
experience.
[0007] According to a spectacular preferred embodiment, the second drive means are configured
to move the passenger gondola along a defined contour, preferably a contour in figure
of eight form. The figure eight is a smoothly continuous path of movement with large
changes in the direction of movement close to the highest point.
[0008] According to a practical preferred embodiment, the second drive means comprise a
number of hydraulic cylinders, preferably two hydraulic cylinders, each acting in
opposite direction. According to a further development of the practical preferred
embodiment, the second drive means comprise control means for controlling the movement
of the hydraulic cylinders.
[0009] The invention will now be described in more detail with reference to the figures.
Figure 1 shows a schematic view of the attraction according to the invention in a
first position;
Figure 2 shows a schematic view of the attraction according to the invention in a
second position;
Figure 3 shows a schematic top view of the attraction according to the invention;
and
Figure 4 shows a part of the attraction according to the invention in more detail.
[0010] The same components are provided in all figures with the same reference numerals.
[0011] Figures 1 and 2 show a preferred embodiment of the attraction according to the invention
in two different positions. Figure 1 shows attraction 1 in the lowest position. This
is also the starting position and the end position, and thereby the embarkation and
disembarkation position. Figure 2 shows attraction 1 during operation in a higher
position.
[0012] Attraction 1 comprises four towers 2 placed some distance from each other on a surface.
In the shown preferred embodiment attraction 1 takes a mobile form and the surface
is formed by a mobile base frame 100. Attraction 1 is mounted on base frame 100 for
collapsing to a transport position. Base frame 100 also forms a platform 111 for embarkation
and disembarkation of the passengers between rides. Attraction 1 can of course also
be assembled at a fixed location, wherein the towers are for instance placed on a
platform.
[0013] Towers 2 are disposed in pairs. Each pair of towers is disposed at a slight incline
in the direction toward the other pair of towers. Towers 2 support a main shaft 3
which is preferably supported in bearing-mounted manner by upper ends 2A of towers
2. Main shaft 3 will generally extend substantially horizontally during operation.
This is not however essential. A pendulum arm 4 is rotatably mounted on main shaft
3. First drive means (not shown) are provided for movement of pendulum arm 4 in a
plane V extending substantially perpendicularly of main shaft 3 between towers 2.
[0014] Pendulum arm 4 comprises two parts 4A and 4B which are connected to each other for
pivoting about a shaft 5. First part 4A is rotatably mounted on main shaft 3 and second
part 4B is provided on the outer end with at least one passenger gondola 11 with seats
12. In the shown preferred embodiment six gondolas 11 are arranged in one gondola
cross 10. Each gondola 11 is provided with two seats 12. The capacity per ride amounts
in this preferred embodiment to twelve seats.
[0015] Second drive means are provided for the purpose of moving second part 4B of pendulum
arm 4 in a direction substantially perpendicularly of the plane of movement. The second
drive means are configured to move second part 4B in two opposite directions Z1, Z2.
In the preferred embodiment directions Z1, Z2 are each substantially perpendicular
to the plane of movement V and to shaft 5. The directions Z1, Z2 each run substantially
parallel to main shaft 3. The second drive means are preferably configured to move
passenger gondolas 11 along a defined contour or curve C, preferably a contour in
figure of eight form. Figure 3 shows a schematic top view of the attraction according
to the invention in which the contour C is illustrated. The gondolas move along a
path which generally has a figure of eight form and is designated as contour C. As
they pass through the path of movement the passenger gondolas perform repetitive forward
and rearward pivoting or swinging movements and simultaneous lateral pivoting movements.
As a result the passenger gondolas move through angles of approximately 120 degrees.
[0016] A preferred embodiment of the second drive means is shown in figure 4. In the preferred
embodiment the second drive means comprise at least one hydraulic cylinder 15 mounted
on pendulum arm 4 close to hinge connection 5. In the shown preferred embodiment there
are two hydraulic cylinders 15, each mounted on pendulum arm 4 on either side of hinge
connection 5. Cylinders 15 provide for the lateral pivoting of arm part 4B relative
to arm part 4A in the two opposite directions Z1, Z2. The hydraulic cylinders also
limit the lateral movement to a safe maximum value. If necessary, mechanical stops
can be fitted in order to guarantee the maximum outward movement of gondola cross
10. As an alternative to the hydraulic cylinders, the second drive means can also
take an electrical form with for instance a spindle motor.
[0017] The second drive means also comprise control means for controlling the movement.
Suitable control means for hydraulic cylinders 15 are positioned-actuated. In the
lowest swing position of the passenger gondola shown in figure 1 it is preferably
the case that the resultant force on the passenger gondola in the lateral directions
Z1 and Z2 is zero. In the highest swing position of the passenger gondola shown in
figure 2 it is preferably the case that the resultant force on the passenger gondola
in the lateral direction Z1 or Z2 is at a maximum. The control means preferably take
an electronic form. When the spindle motor is applied, the control means are configured
in similar manner for proportional control.
[0018] The inventive concept is based on the insight of adding smaller lateral pivoting
movements to a large pivoting movement of the passenger gondola. In the preferred
embodiment the gondola follows a path of movement in figure of eight form. The path
of movement can however also take different forms, such as an X-shape.
[0019] It is noted that suitable first drive means are per se known in the relevant field.
Several non-limitative examples are: an internal upper drive with transmission which
is accommodated in part 4A or an external upper drive with transmission on towers
2, wherein the two upper drives engage directly on main shaft 3, or a lower drive
which engages on and accelerates the gondola. The lower drive can for instance comprise
a running wheel which makes contact with the underside of the gondola. The form of
the gondola has to be adapted hereto. A suitable form is for instance a ship. The
lower drive can be accommodated in base frame 100 or in a fixed platform.
[0020] It will be apparent that the capacity of the attraction according to the invention
can be adapted to the conditions. This is possible by adapting the number of seats
per gondola, the number of gondolas per gondola cross and the number of gondola crosses
per pendulum arm. All these variants lie within reach of a skilled person after reading
of this text.

but extends to any embodiment falling within the scope of protection as defined in
