[0001] The present invention relates to an attraction particularly for fun parks, amusement
parks and the like.
[0002] Different types of attractions for fun parks have already been proposed, and in particular
of the nacelle type, i.e. comprising an element on which at least one group of seats
for passengers is mounted, which is made to rotate about one or more axes.
[0003] For example, in the attraction described in European Patent
EP0613706B1, the nacelle may rotate about a horizontal axis as it is mounted suspended and rotatable
at an end terminating in a fork, of a support arm at the other end of which is a counterweight.
The support arm, in intermediate position with respect to the two ends thereof, is
hinged, rotatable on a horizontal axis, parallel to the one of rotation of the nacelle,
with respect to the forked end, and supported by support columns. The fun for the
passengers is generated by the rotations about a horizontal axis of the nacelle mounted
on the support arm, which in turn will rotate, like a pendulum, about another horizontal
axis, parallel to the one of rotation of the nacelle.
[0004] Another "nacelle" type attraction of known type is described in American Patent
US5188566A. In this attraction, instead of a forked end of a support arm, a pair of parallel
arms is used, at one end of which a nacelle rotatable about a horizontal axis is hinged,
with rows of seats for passengers, parallel to the latter axis, and at the other end
of which a counterweight is provided. The pair of parallel arms, in intermediate position
with respect to the two ends, is also hinged rotatable about a horizontal axis, parallel
to the one of rotation of the nacelle, which due to some support columns at variable
height, may raise the two parallel arms to the wanted height. What is certain is that
when the arms begin rotating about the horizontal axis like a pendulum, passengers
will perform both a circular trajectory or arc, and they will rotate integrally both
clockwise and counter clockwise with the nacelle about the horizontal axis of rotation
thereof. In this second example, the axis of rotation of the nacelle and the one of
rotation of the two support arms are also substantially parallel.
[0005] In International Patent
WO03041826A1, reference is made to a fun park attraction comprising a support column, bottomly
and rotatably constrained to a base which is integral with the ground and free at
the top. A nacelle is constrained with sliding engagement to said support column and
is intended to be capable of sliding thereon from the upper end to the lower one and
vice versa. The attraction is characterized in that the lower end of the support column
may rotate about a horizontal axis being reciprocally hinged with the base: the support
column can thus move like an upside-down pendulum. In this type of known attraction,
the nacelle will move along the column, but it is not provided for it to rotate with
respect thereto.
[0006] In Patent
DE202004001477U1, a type of known attraction is described consisting of a "tower-like" middle support
element, which is slidingly hinged with a nacelle which can longitudinally lie thereon.
An end of the middle element, equipped with counterweight, is constrained to a base
by means of a universal joint, and can move radially therein with the restriction
set by specific stops. The "tower-like" middle element can thus be inclined with respect
to the vertical, and the upper end thereof can thus describe closed curvilinear trajectories.
It is provided that the nacelle move along the middle element, but it is not provided
for it to rotate with respect thereto.
[0008] It would be desirable to have a fun park attraction which involves the passengers
in rotations with an increased level of freedom, thus increasing the fun.
[0009] The main object of the present invention is to provide a fun park attraction, which
ensures satisfaction and fun for its passengers in complete safety.
[0010] Another object of the present invention is to provide a fun park attraction, which
is capable of transmitting accelerations along different directions to its passengers.
[0011] A further object of the present invention is to provide a fun park attraction both
of the fixed installation type and of the movable type and transportable for travelling
use.
[0012] In accordance with the invention, such an object is achieved with a fun park attraction
as described in claim 1.
[0013] These and other features of the present invention will become more apparent from

and
figure 11 shows a perspective view of a sixth embodiment of a fun park attraction
according to the present invention.
[0014] With reference to the above-listed figures from 1 to 3, it will be noted how, in
a first embodiment, a fun park attraction 1 comprises a base resting on the ground
2, from which a support upright 4 overhangingly extends, substantially vertical, i.e.
orthogonal to said base 2, having, if desired, a rectangular section with a lower
end 42, which dimensions are longitudinally increased with respect to base 2, i.e.
at the connection with the latter. The support upright 4 will support, at the free,
upper end 41 thereof, driving means 5 connected with a rotating arm 6. The axis of
rotation of the driving means 5 will not be perfectly horizontal but inclined, slightly,
by an angle β e.g. of 15° (see fig. 3). As will be particularly noted in figures 2
and 3, the axis of rotation V-V' of the driving means 5 and the axis of symmetry S-S'
of the rotating arm 6 are perfectly parallel and on the contrary, there is an angle
α between axis S-S' and axis V-V', between 20° and 30°, if desired. The rotating arm
6 has one end 61 rotatably constrained to the support upright 4 by means of the driving
means 5, and a second end 62 connected perpendicular close to the median point of
a forked element 8, substantially describing a semi-circular broken line ending with
a pair of ends 81 and 82. Said ends 81 and 82 lie on an axis O-O' substantially orthogonal
to axis S-S' of the rotating arm 6. The two ends 81 and 82 rotatably support the two
ends of a cross member 10, with substantially U-shaped profile, at the median point
of which, and more precisely in the concave part thereof, support means 12 for passengers
15 are rotatably constrained. In particular, said support means 12 for a certain number
of passengers 15, e.g. one dozen, are called "nacelle" 12 in jargon. In the example
at hand, nacelle 12 consists of a disc-shaped element 13, which along the perimeter
thereof, supports a group of seats 14 of known type, equipped with known safety means
141, for passengers 15. Nacelle 12 can rotate with respect to the cross member 10
along the axis of rotation T-T' substantially orthogonal to the axis of rotation O-O'
of the cross member 10 with respect to the forked element 8. The rotation of nacelle
12 about axis T-T' can be idle or motorized by comprising driving means 17 and, preferably,
a braking system 18 is provided for controlling the rotation speed of nacelle 12 about
axis T-T'. Base 2 can provide a small ladder 20, preferably of retractable type.
[0015] With reference to the above-listed figures from 4 to 6, it will be noted how, in
a second embodiment, a fun park attraction 1 comprises a base resting on the ground
2, from which a support upright 4 overhangingly extends, hinged at an end 42 thereof
to said base 2. The other end 41 of the support upright 4 is constrained to said base
2 by means of the lifting elements 22, consisting of hydraulic cylinders of known
type, if desired. Hinged at the end 41 of the support upright 4, preferably having
substantially rectangular section, is an articulated joint element 23, substantially
consisting of a pair of parallel triangular plates 24. A vertex 241 of plate 24 is
exactly hinged with end 41 of the support upright 4, another vertex 242 of plate 24
is connected to an end 251 of a contrasting tie rod 25 in turn hinged, with its end
252, to said base 2. Connected to the third vertex of the two triangular plates 24
are driving means 5 on which a rotating arm 6 is mounted which, with respect to the
first embodiment of the fun park attraction 1, will be much shorter. Similarly to
the first embodiment shown in figures from 1 to 3, the rotating arm 6 in the second
embodiment shown in figures 4 and 5 is also connected to a forked element 8 supporting
similar nacelle 12. The substantial difference between the first and the second embodiment
is that, in the example shown in figures 1-3, the axis of rotation V-V' of the driving
means 5 has a predefined angle β with respect to a horizontal plane, while in the
second example shown in figures 4 and 5, the axis of rotation V-V' of the driving
means 5 will vary as the position varies of the two rectangular plates 24, i.e. based
on the length taken on by the two lifting elements 22.
[0016] With reference to fig. 6, it will be noted that the fun park attraction 1 will differ
from the one in figures 4 and 5 due to the fact that a different type of nacelle 12
was used other than the one disclosed above, coupled at the ends 81 and 82 of the
forked element 8 by means of a straight cross member 10, in the median point in which,
integral with said cross member 10, but rotatable about an axis T-T', orthogonal to
the axis of rotation O-O' of said cross member 10 with respect to said forked element
8, a group of arms 26 is connected, radially arranged, angularly equally spaced, if
desired, at the free ends of which groups of seats 14 of known type are connected
for passengers 15.
[0017] Figures 7 and 8 show two possible versions of nacelle 12 disclosed above and shown
in figure 6. In particular, nacelle 12 in fig. 7 consists of a cross member 10, suitable
for being coupled with said forked element 8, having a slight curvature in median
position, in which concavity, as occurs in nacelle 12 in fig. 6, a group of arms 26
is connected, radially arranged, angularly equally spaced, if desired, at the free
ends of which groups of seats 14 of known type are connected for passengers 15. The
peculiarity of the arms 26 of the nacelle in figure 7 is that said arms 26 are curved
as though they were lying substantially on a spherical-cap shaped surface with the
concavity oriented from the same part as the one of the cross member 10.
[0018] The nacelle in figure 8 differs from the one in figure 7 because the arms 26 are
not angularly equally spaced but are close to each other in pairs, and groups of seats
14 of known type, for passengers 15 are connected to their adjacent free ends.
[0019] With reference to figure 9, it will be noted how a third embodiment of a fun park
attraction 1 is substantially a variant of the embodiment shown in figures 4 to 6
where a nacelle 12 was used consisting of two rows of groups of seats 14, parallel
and backs opposed, mounted parallel on a support cross member 10, parallel to the
axis of rotation O-O', which two ends are rotatably connected in the ends 81 and 82
of the forked element 8.
[0020] The base resting on the ground 2 can be conveniently replaced by a towable semitrailer,
if an installation that is movable as required - or better yet is travelling - is
opted for.
[0021] In practice and with reference to the first embodiment of the fun park attraction
1, i.e. the attraction described in figures 1 to 3, the passengers 15 will access
nacelle 12 by climbing ladder 20, which will initially be positioned at the height
of nacelle 12 to then be retracted so as not to interfere with moving elements of
attraction 1. Once on board nacelle 12, each passenger will sit down in his/her own
seat 14, remaining anchored there due to provided safety means 141. Once all the passengers
15 are in their seats 14, computerized control systems will activate the driving means
5, which depending on the program wanted, will cause the rotating arm 6 to perform
complete turns, both clockwise and counter clockwise, about the axis of rotation V-V',
or partial rotations. In fact, as the axis of rotation V-V' of the rotating arm 6
is generally, but not necessarily, inclined by an angle α with respect to the axis
of symmetry S-S' of the rotating arm 6, end 62 of the rotating arm 6 will describe
a circular trajectory each time said rotating arm 6 performs one turn. With respect
to when they climbed onto nacelle 12, the passengers 15, due to a half turn by the
rotating arm 6, will be upside down and the balance of nacelle 12 will be unstable
and hence it will tend to return to stable balance by performing some rotations about
axis O-O' while passing through the two ends 81 and 82 of the forked element 8. Moreover,
nacelle 12 can simultaneously be placed into rotation along axis T-T' by means of
the driving means 17, which are equipped with braking means 18 for controlling the
accelerations to which the passengers 15 are subjected during the rotation of the
rotating arm 6 about axis V-V', of nacelle 12 about axis O-O' and of axis T-T'.
[0022] All the other embodiments of the fun park attraction 1 share the fact that the support
upright 4 may bring itself from a lowered position, in which it is substantially parallel
to base 2, to a raised position in which, due to a rotation of an end 42 thereof,
hinged to base 2, the end 41 thereof is moved away from base 2, pushed by the lifting
elements 22. In the raised position, attraction 1 stands out for the fact that the
rotating arm 6 also moves away from base 2, and as axis V-V' will be inclined with
respect to base 2, end 62 of the rotating arm will also be lifted. In the embodiments
in figures 4, 5, 6 and 13, the raised position of attraction 1 will also lead to a
raised height for nacelle 12.
[0023] In particular, nacelle 12 in the embodiments in figures 4, 5 and 6, equally to the
embodiment in figures 1 to 3, can rotate about axis V-V' of the driving means 5, axis
O-O' passing through the ends 81 and 82 of the forked element 8, orthogonal to axis
V-V', to the axis of rotation T-T' of the driving means 17, orthogonal to axis O-O'.
The rotation of nacelle 12 about axis O-O' causes axis T-T' to describe a plane on
which axis V-V' of the driving means 5 will lie.
[0024] With reference to the embodiment in figure 9, with respect to the one shown in figures
4 to 6, a nacelle 12 was replaced with a disc-shaped base, or however rotating about
axes T-T' and O-O', with a nacelle 12 only rotating about axis O-O' and hence with
one less degree of freedom. This fact results in the passengers 15 being subjected
to the accelerations only caused by the rotations about the axes V-V' and O-O'.
[0025] Similarly to the above disclosure, the passengers 15 will feel the accelerations
generated by the rotation of the rotating arm 6 about axis V-V' and of the rotation
of the support axles 34 for groups of seats 14 about axis O-O', the degree of freedom
of the rotation about axis T-T' lacking in this embodiment. The rotation on axis O-O'
causes the passengers 15 to perform somersault trajectories.
[0026] Figure 12 shows a fourth embodiment of a fun park attraction 1 according to the present
invention, in which the support upright consists of a vertical column 4 which rigidly
supports a fixed inclined arm 51 at one end 52 of which a motorized rotating element
53 is associated, which is driven by driving means 5, adapted to rotatably support,
by means of connection means 8, a nacelle 12 for example similar to the one shown
in figure 1.
[0027] With respect to the embodiment in said figure 1, the rotating element is substantially
a plate 53, in place of arm 6, which first end 55 is rotatably associated with the
fixed arm 51, and having a second end 54 supporting nacelle 12 by means of connection
means 8.
[0028] Advantageously, in any one of the above-described embodiments, the connection means
of nacelle 12 may comprise jointed means, for example arms connected by means of articulated
joints.
[0029] In practice, any materials and also dimensions may be used, depending on the needs.
