Definitions

  • the subject of the present invention is a carousel of the so-called "grasshopper” type, in which there is provided a carousel structure rotatable about the axis of a central hub and having a plurality of arms, extending radially from the hub, that are actuated by pneumatic jacks or other similar actuators capable of imparting rapid accelerations, in such a way that during the rotation of the carousel structure the arms are subjected to sudden lifting movements and jerky descents, just like the hopping motion of a grasshopper.
  • the carousel passengers are seated in respective cradles carried at the end of each arm and therefore experience the play effect of the sudden accelerations and decelerations of the cradles, abruptly lifted and lowered with a possible series of "rebounds" while the carousel structure rotates about its own axis.
  • the aim of the invention is that of improving the play effect to which the passengers on this type of carousel are subjected.
  • a carousel of the grasshopper type produced according to the present invention is indicated as a whole by 1.
  • the carousel 1 comprises a carousel structure 2 typically including a plurality of arms 3 extending radially from a central hub 4 rotatable about its own vertical axis X.
  • Each arm 3 has its fulcrum on the hub 4 by one of its ends 5 and bears a passenger-carrying cradle 6 at the opposite end.
  • a pneumatic jack 7 capable of causing a plurality of sudden lifting and lowering movements of the arm 3 and corresponding cradle 6 during the rotation of the hub 4 about its own axis X.
  • pneumatic jacks as actuators for the movements of the arms is preferential in as far as they allow on the one hand the sudden accelerations required for the correct functioning of the lifting movement of the arms, with consequent extension of the jacks 7, and on the other hand serve to dampen the descent thereof, with the consequent possibility of either an equally sudden descent or a descent in the form of jerks, transformed by the damping effect into so many hops.
  • the arms may be actuated otherwise, for example by means of hydraulic, electrical, mechanical or similar actuators, optionally complemented by suitable damping means.
  • Figure 5 illustrates a possible example of actuation of the arms, where the time expressed in seconds is entered on the abscissa, and the acceleration of the cradle consequent upon the movement of the arms 3 is entered on the ordinate.
  • the rotation velocity of the hub is approximately 8 r.p.m.
  • the whole of the data identifies the type of motion characteristic of a possible exemplary embodiment of a grasshopper carousel.
  • each cradle 6 is supported on the respective arm 3 so as to be rotatable about a cradle axis 8 substantially perpendicular to the respective arm 3.
  • the support is loose, or rather the cradle 6 is free to rotate about the cradle axis 8; it is also envisaged, however, that the rotation control may be motorized.
  • the cradle axis 8 preferably does not lie on the centre of gravity with respect to the cradle 6 (and to the load represented by the passengers), such as to accentuate a rotation of the cradle about the cradle axis as a result of the movements of the arm.
  • the cradle 6 is in fact made with a frame 9 suspended by means of a pin 10 with axis 8 at the end of the arm; the frame 9 carries a pair of seats 11 with back-rest 12 and arm-rests 13 and is equipped with retaining devices 14 such that, once they are closed on the shoulders of the passenger, the latter is held firmly accommodated in the seat 11.
  • braking means such as a disc brake 16 and corresponding caliper 17 are arranged which serve to lock the relative rotation between the cradle and the arm about the cradle axis 8.
  • the operation of the carousel 1 is as follows. In order to facilitate the embarkation of the passengers, with the carousel at a standstill the braking means charged with locking the cradles are actuated. In a manner that is known per se, the retaining devices 14 rise up so as to give access to the seats 11, and the passengers embark.
  • the invention thus improves the play effect of a conventional grasshopper carousel, obtaining further advantages owing to the fact of obtaining the rotatory movement of the cradle without the need for specific motorization.
