- Such a mobile Ferris wheel is known in the relevant technical field. The
European patent EP2055362 of the same applicant for example describes a support structure for a mobile Ferris wheel. The known mobile Ferris wheel is intended as moveable (fairground) attraction and can be build up and broken down in a quick and safe manner.US2003162596 discloses a transportable Ferris wheel comprising a supporting structure composed of two pairs of masts, each pair bearing on their top end a head part. The wheel is rotatably supported on the head. The masts can be folded down into a container for transportation and raised again until they are in the fully extended position, in which the supporting structure is ready. Before the masts are raised, the head is assembled by connecting the two head parts of the pairs of masts to each other. - The present invention aims to provide an improved mobile Ferris wheel, which can be build up and broken down even quicker and safer.
- The Ferris wheel according to the present invention is thereto characterized in that the Ferris wheel comprises a first shaft, which is mounted fixedly on the top of the first pair of masts, wherein a first of the two spoke rings is arranged rotatably around the first shaft, that the Ferris wheel further comprises a second shaft, which is mounted fixedly on the top of the second pair of masts, wherein a second of the two spoke rings is arranged rotatably around the second shaft, wherein, in use of the Ferris wheel, the second shaft is substantially in line with the first shaft at a distance from the first shaft.
- The Ferris wheel according to the invention has to its advantage that is does not comprise a main shaft anymore. Consequently, the usage of a crane when building up and breaking down the Ferris wheel is no longer needed. The known Ferris wheels with main shafts need a crane during build up for placing the main shaft on the masts and during break down for removing the main shaft from the masts. A crane takes up a lot of space and when driving it onto the site one often has to wait for this space to be available.

It is also safer, because a heavy main shaft no longer has to be lifted onto the masts. Furthermore, a main shaft is usually custom made in a separate production step, which can now be omitted. The production of the Ferris wheel according to the invention is therefore cheaper than that of a Ferris wheel with main shaft.
- In a first preferred embodiment each spoke has two legs that run substantially parallel that are connected to each other by means of a number of rods, wherein a first mounting element on an end of a first leg is arranged for mounting in the first spoke ring and a second mounting element on an end of a second leg is arranged for mounting in the second spoke ring, wherein the spoke is provided with a first crossbar that connects the legs near the ends. The usage of these double spokes contributes to the stiffness of the Ferris wheel according to the invention. Moreover, the building and breaking down happens quicker when using double spokes.
- In an elegant preferred embodiment the spoke rings are mounted on ends of the first and second shaft that are facing each other. The first shaft and second shaft can then be made as short as possible. The weight and costs of short shafts are lower. A stub axle is for example very suitable as an application for both the first shaft and the second shaft.
- The present invention also relates to a method for building the Ferris wheel according to one of the preceding claims, wherein the method comprises the following steps
- a) jointly raising the first pair of masts with the first shaft to the stretched position;
- b) jointly raising the second pair of masts with the second shaft to the stretched position;
- c) outlining the first and second shaft on a common axis of rotation;
- d) mounting the spokes in the first spoke ring and in the second spoke ring; and
- e) connecting the spokes with the ring segments.
