DESCRIPTION:
BRIEF SUMMARY
This invention relates to a fairground device comprising a base disc driven for rotation about a central axis and a plurality of seat supports mounted in spaced relation relative to the central axis for rotation about a second axis, each of the seat supports carrying a plurality of seats mounted eccentrically relative to the corresponding second axis.
Such a fairground device is known from European patent application 0082435. In this known device, the seats are rotatable about the axis of the associated seat support. During operation of such a device, the passenger simultaneously experiences the sensation caused by the rotation of the base disc and the sensation caused by the seat rotating about the second axis spaced from the central axis of the base disc.
To modify this combination of sensations, which was already known as such, it is proposed in European patent application 0082435 to slightly incline the axis of rotation of the seat supports relative to the central axis of the base disc. As a result, the level of the seat during rotation about the second axis varies.
The shaft of the second axis can be mounted on the base disc as well as on a rotatable intermediate disc mounted on the base disc. Further, the central axis of the base disc of the known device can optionally be slightly inclined.
The object of the invention is to increase the thrill of the sensation aroused by the known devices, i.e. the above-described devices, which may or may not comprise intermediate discs and may or may not be provided with an inclined central shaft and/or an inclined second shaft.
To that end, according to the invention, a fairground device of the type described hereinabove is characterized in that the seats are mounted on the seat supports for rotation about a third axis extending transversely to the second axis.
As will appear from the following, the base disc may alternatively consist of a hub with a plurality of radial arms.
Hereinafter, the invention will be further described with reference to the accompanying drawings of some embodiments. In said drawings:
FIG. 1 is a diagrammatic side elevation of a part of a fairground device according to the invention;
FIGS. 2, 3 and 4 are diagrammatic views of a part of a device according to FIG. 1 in three different positions of the seats during operation;
FIG. 5 is a diagrammatic top plan view of a part of a second embodiment of a fairground device according to the invention;
FIG. 6 is a diagrammatic view of yet another variant of a device according to the invention;
FIG. 7 is a diagrammatic view similar to the view of FIG. 1, of yet another embodiment of a fairground device according to the invention; and
FIGS. 8--12, by way of example, are diagrammatic views of some embodiments of seat supports with associated seat configurations.
FIG. 1 is a diagrammatic view of a fairground device 1, comprising a base plate 2 having a base disc 4 mounted thereon for rotation about an axis 3. The base disc 4 can be driven for rotation about the axis 3 by means of a diagrammatically shown motor 5, which may be an electric motor or a hydromotor.
The base disc can be arranged horizontally but in practice often makes an angle .alpha. with the horizontal, as shown in FIG. 1.
In this embodiment, the base disc 4 mounts a plurality of intermediate discs 6 each driven for rotation about an axis 7 by means of a motor 8. Arranged adjacent the perimeter of an intermediate disc 6 are one or more seat supports 9. The seat supports are mounted on the intermediate disc 6 for rotation about an axis 10. The movement of the seat support 9 relative to the intermediate disc 6 may be loose or driven. In this embodiment, the seat support is of L-shaped design, viewed in side elevation, the axis 10 being located adjacent the free end of the short horizontal leg of the L-shaped seat support.
The upright leg of the L-shaped seat support may in turn be U-shaped, as shown in FIG. 8, so that a seat 11 can be mounted between the legs thereof. The seat 11 is mounted for rotation relative to a transverse axis 14. Acc
