By using a single rope loop it is achieved that the two rope loops run synchronously.

Description

DRIVE FOR FERRIS WHEEL
Field of the Invention The invention relates to recreational devices with a positionally fixed supporting structure, transport means for persons which circulate thereon, and a rope drive for the transport means.

Background of the Invention A recreational device of said type is known from EP A 459 789. There, the cabins are driven by means of two endless drive ropes which are driven by a motor. 'The disadvantage of that construction is that it is only possible with a very high degree of technical expenditure to ensure that the two separate rope loops run synchronously. It is not sufficient to simply run the two drives at the same rotational speed because even small differences in diameter or circumference of the drive disks would lead to different conveying speeds of the two rope loops.

Summary of the Invention The invention is therefore based on the object of providing a drive for a recreational device of the generic type specified in the introduction, with which it is ensured that the two rope loops run synchronously.
This object is achieved by modifying a generic recreational device by providing one single closed-loop conveying rope which is crossed over by means of a deflecting device to form two rope loops which each engage the transport means.
Since the invention provides only one single endless rope which is placed around the supporting structure and is connected to the transport means in two rope loops, synchronous running of the two rope loops is automatically ensured.
Various embodiments are preferred for connecting the two rope loops to the transport means.
In one embodiment, the conveying rope engages on the transport means by way of a frictionally locking connection, and at least one lockable pulley is mounted on the transport means, with the conveying rope bearing on said pulley. In this embodiment, the connection is very simple since it is provided only by the friction caused by the conveying rope bearing firmly against a corresponding contact region of the transport means, in particular against the running gear thereof.
In another preferred embodiment, the conveying rope is connected to the transport means using detachable clamps. This embodiment ensures an even firmer connection between the conveying rope and the transport means, though with a relatively high degree of technical expenditure for the detachable clamps.
With regard to the deflecting device and the drive for the rope, the deflecting device of the invention have two drive disks which are mounted adjacent to one another so as to be coaxial, and a pair of deflecting rollers, which are mounted adjacent to one another, at the run-in side before the deflecting device and at the run-out side after the deflecting device.
In a first variant in accordance with the invention, the drive disks are driven in opposite directions, and the deflecting rollers are mounted with their axes parallel to one another.
In a second variant in accordance with the invention, the drive disks are driven in the same direction, in that one pair of the deflecting rollers is mounted with their axes coaxial, another pair of deflecting rollers is mounted with their axes oriented at an angle relative to one another, a guide device is arranged in the region of said other pair of deflecting rollers, and the rope loops cross one another between the guide device and the other pair of deflecting rollers.

Detailed Description Figure 1 illustrates an oblique view of a recreational device according to the invention, which is generally also referred to as a "Ferris wheel". The recreational device has a positionally fixed, rigid supporting structure 1 which is embodied, for example, as a reinforced concrete ring, on which transport means 2 in the form of cabins circulate. The outer face 4 of the supporting structure is - with the exception of the entry and exit region 3 situated at the bottom - cylindrical, but may have a shape which deviates from this and can be, for example, elliptical. In the entry region 3, the outer face 4 is straight in order to provide a relatively long horizontal entry region (not illustrated in detail) for the passengers. The drive 5 is arranged below the entry region 3 and is in practice arranged in a machine housing so as to be hidden from view.
Rails 6 are attached to the outer circumferential face 4 of the supporting structure 1, with running rollers 7, which are mounted on a running gear 8 of the cabins 2, rolling on said rails. The individual cabins 2 are connected to one another and held at a defined distance from one another by means of one or more connecting ropes 9 which are fixedly connected by means of clamps 10 to the running gear 8 of each cabin 2. It is also possible to provide other connecting means instead of the connecting ropes 9. It is however advantageous to use three connecting ropes 9 because this provides a very stable and secure connection between the cabins 2.
Figure 3 also shows a further two pairs of running rollers 11 per running gear 8, said further running rollers 11 serving to support the cabins 2 when the latter are suspended in the entry and exit region 3 below the structure 1.
Platforms, if appropriate with seats (not shown), are arranged in the cabins 2, said platforms being kept horizontal at all times by means of suitable devices while the cabins rotate as they circulate around the supporting structure 1.
The cabins 2 are driven by means of one single closed-loop rope 12 which, in two loops 12a and 12b, engages at both sides of the cabins 2 over the running rollers 7 on the running gear 8 of the cabins 2. In this embodiment, the running rollers 7 serve at the same time as friction rollers so that, as a result of the synchronous progressive movement of the two rope loops 12a and 12b, a propulsive force is exerted on the running rollers 7 by means of friction forces, said propulsive force moving the cabins 2 forwards. As a result of the selected form of force transmission, the cabins 2 move at half the speed of the two rope loops 12a and 12b of the conveying rope 12.
In the embodiment illustrated in figure 4, the running rollers 8 are of a different design to those in the embodiment of figure 3, specifically in the form of a total of twelve running rollers, four pairs of which are arranged on one side of the rails 6, and the other four individual rollers of which roll on the opposite, inner side of the rails 6.
The number of running rollers can vary depending on loading.
Figure 4 also illustrates a different form of connection between the rope loops 12a and 12b and the running gear 8. In this embodiment, the rope loops 12a and 12b engage on separate friction wheels 13 which, although being rotatably mounted on the running gear 8, can be locked so that they do not rotate for normal operation.
The cabins are conveyed at the same speed as the rope loops 12a and 12b as a result of the friction between the rope 12 and the friction wheels 13. The function of the rotatable mounting of the friction wheels 13 will be explained further below.
A first preferred embodiment of the invention is shown in figure 5. Two drive disks 14, which are driven by motors 15, are provided in the region of the drive 5. The drives rotate at the same speed, but in opposite directions. Synchronous running of the two drive disks 14a, 14b is obtained either by control-related means or by mechanically coupling the two drives. Above the drive disks 14a, 14b, two pairs of deflecting rollers 16a, 16b and 17a, 17b are provided, the rotational axes of which are arranged offset relative to one another. Said offset arrangement of the deflecting rollers makes it possible for the two rope loops 12a and 12b to cross in the region of the drive 5. In physical terms, the rope of the rope loop 12a which runs in from the left in figure 5 runs over the deflecting roller 16a and the drive disk 14a, is then guided over the deflecting roller 17b, and runs out of the drive 5 in the rope loop 12b. In contrast, the rope of the rope loop 12b which runs in from the left is guided over the deflecting roller 16b to the drive disk 14b, and runs over the deflecting roller 17a and out of the drive unit 5 in the rope loop 12a. In other words, the rope 12 is switched from the rope loop 12a through the drive unit 5 to the rope loop 12b, and from the rope loop 12b to the rope loop 12a.
Absolutely synchronous running of the two rope loops 12a and 12b is ensured as a result of the two rope loops 12a, 12b being formed by one single closed-loop rope, so that it is ensured that the cabins 2 run without tilting, which not only minimizes the expenditure in mounting the running gear 8 on the rails 6 of the supporting structure 1, but also keeps the wear of the running gear and of the rails as low as possible.
After assembly of the recreational device according to the invention, the drive 5 must initially be run-in. This is necessary since it is not possible for the two drive disks 14a and 14b to be produced with such a degree of accuracy that they have exactly the same diameter and circumference, which is required since only one single encircling rope is used, and the two rope loops 12a, 12b must therefore be driven at the same speed.
The running-in process eliminates geometric differences between the two drive disks 14a and 14b, primarily as a result of mechanical abrasion on the drive disks 14a and/or 14b. It is however advantageous if the cabins 2 do not have to be driven during said running-in process. It is for this reason that the friction rollers 13 in the embodiment of figure 4 are initially freely rotatable, so that the conveying rope 12 can roll on them without moving the cabins 2. The friction rollers 13 are only locked once the running-in process is complete, so that the cabins 2 move at the same speed as the rope 12 as a result of the frictionally locking connection between the rope 12 and the friction rollers 13.
As can be seen from the drawings, the rope 12 bears against the running rollers 7 and friction rollers 13 from the outside so that, in addition to the taut connecting ropes 9, the taut rope 12 also presses the running gears 8 of the cabins 2 firmly against the rails 6. At the start of the entry and exit region 3, however, the rope 12 moves away from the running rollers 7 and the friction rollers 13 since the rope 12 is conveyed directly to the deflecting rollers 16a, 16b, whereas the guide track 4 with the rails 6 continues horizontally. Until contact is regained between the rope 12 and the running rollers 7 and friction rollers 13 at the end of the entry and exit region 3, the cabins 2 are driven by means of the connecting ropes 9, by means of which the running gears 8 of the cabins 2 remain held pressed against the rails 6. As mentioned, the running rollers 11 (figure 3) or the radially inwardly situated running roller pairs 8 (figure 4) are additionally provided, said running rollers 11 or running roller pairs 8 preventing the suspended gondolas 2 from lifting off the rails 6.
Instead of a frictionally locking connection between the rope 12 and the running gear 8 in the form of friction rollers 13 (figure 4) or running rollers (figure 3), it is fundamentally also possible to provide other forms of connection between the rope 12 and the running gears 8. For example, detachable coupling elements could be provided on the running gears, by means of which detachable coupling elements the cabins 2 are decoupled from the rope 12 at the start of the entry and exit region 3, and are re-coupled to the rope at the end of said region.
Figures 7 and 8 illustrate an alternative embodiment of a drive 5. Two drive disks 18a and 18b are again provided, though in this embodiment said drive disks 18a and 18b rotate in the same direction and are rigidly connected to one another by means of a shaft 21. The drive disks 18a and 18b are driven by one or two motors 22, it being preferable to use two motors 22 since, if one motor fails, the operation of the recreational device can continue, if appropriate with reduced power, by decoupling the failed motor from the shaft 21.
A second preferred embodiment in accordance with the invention is illustrated in figures 7 and 8. Two coaxially arranged deflecting rollers 20a and 20b are provided at the run-out side, and two deflecting rollers 19a and 19b, which are arranged adjacent to one another but with their rotational axes oriented at an angle relative to one another, are provided at the run-in side. In addition, a guide device 23 is arranged at the run-in side before the two deflecting rollers 19a and 19b, said guide device 23 having two pulleys 24a and 24b which are mounted coaxially and rotate counter to one another.
Here, the two rope loops 12a and 12b cross in the region between the guide device 23 and the two deflecting rollers 19a and 19b. In physical terms, the rope of the rope loop 12a which runs in from the left in figures 7 and 8 runs over the upper pulley 24a of the guide device 23 to the deflecting roller 19b and over the drive disk 18b, is then guided over the deflecting roller 20b and runs out of the drive 5 in the rope loop 12b. In contrast, the rope of the rope loop 12b which runs in from the left is guided through over the lower pulley 24b of the guide device 23 and below the rope of the rope loop 12a, and runs over the deflecting roller 19a, the drive disk 18a and the deflecting roller 20a and out of the drive unit 5 in the rope loop 12a.
Although the embodiment of the drive according to figures 7 and 8 requires an additional guide device 23 in comparison to the embodiment of the drive according to figures 5 and 6, said embodiment has the mentioned advantages regarding the synchronous drive of the two drive disks 18a and 18b by means of the mechanical coupling provided by the shaft 21.
