Description

The present invention relates to a carousel according to the preamble of Claim 1.

Such a carousel has an upper one on a central mast mounted rotary carrier on its peripheral area to the outside / inside pivoting support rods are arranged on which gondola or seat support are attached.

A carousel is known from EP 0 325 783, one by one Central mast has a rotating turntable, at the ends of each are arranged substantially vertical axis rotatable gondola support have several hanging gondolas. When the gondola carrier rotates are the individual gondolas due to their freely movable suspension on Gondola carrier under the influence of centrifugal force to the outside around the axis of rotation of the Gondola carrier deflected. The gondolas perform a circular movement the axis of the gondola support and taking into account the attachment of the Gondola carriers on the slewing ring execute the individual gondolas opposite the Central mast is a spiral movement in a circle.

To increase the driving stimulus, the axis of rotation of the Deflect the slewing ring from the vertical by an angle so that in addition to the movement shown, an additional vertical opening and closing Downward movement of the passenger gondolas can occur.

From DE 29 52 032 is a carousel with a central mast and upper supports rotatable about the mast axis known at their ends Carrying gondolas, each around a circumferential direction of the carrier Axis are pivotable. The individual arms can move vertically while driving be moved up and down.

In a so-called chain carousel, there is a central one Mast rotatable swivel bracket a Vel number of freely suspended on chains Passenger seats attached to the rotation of the rotating beam under the influence of centrifugal force be deflected outwards. It is also known about a Angular position of the axis of rotation of the rotary carrier to a so-called wave flight achieve. Instead of using chains, it is also known that To secure passenger seats hanging on the rotating beam via rigid rods. The disadvantage of such chain or rod carousels is that during During a journey, the passenger seats only make a circular movement, possibly with additional horizontal movement, perform, due to the Centrifugal force affects the entire interior of the carousel while driving is unused.

DE-GM 72 01 854 is a carousel with several arms known, which are attached to a vertical axis rotatable middle part. The brackets can be swiveled around axes that are tangent to the central section and designed to be raised by driving force. At the ends of the boom rotatable free-hanging seat basket carriers are attached.

DE 32 34 279 shows a carousel with several passenger gondolas are suspended from the booms via freely pivoting gondola arms. Notification Force generators can free the gondolas beyond the centrifugal position can be pivoted.

The subject of DE 87 01 462 relates to a similar one Amusement ride with rigid booms caused by radial force Movable towards the central column, the gondolas on the arms are freely pivoted attached.

From DE 89 08 896 a circular ride with radial through Power actuated pivotable arms, known to those on the arms attached gondolas can also be pivoted power-operated, the are additionally designed with a rotatable pendulum axis.

Finally, DE-PS 44 689 shows the possibility of training a opposite movement of opposite passenger gondolas.

The invention has for its object a new carousel in the The preamble of claim 1 specified type indicate an increase of the driving experience that requires only a small footprint, flexible is controllable, but can nevertheless offer a high useful frequency.

This object is achieved by the one specified in claim 1 Invention. Advantageous developments of the invention are in the subclaims specified.

According to the invention it is provided that the support rods for the gondola or Seat support through a controlled application of force in relation to the orbit of the rotary carrier are pivotable outwards / inwards, the Swivel axis of the support rods on the swivel bracket at an angle to the radial and The circumferential direction of the rotary carrier runs. The flight radius of the gondola or Seat support can be adjusted as desired. It is thus possible to To move the flight radius far inwards towards the mast as well as far deflect outwards, beyond the area that is due to the Centrifugal force influence arise with freely suspended gondola or seat supports would. The determination of the trajectory in this way allows it for example, the operating space of the carousel to a limited space to adapt to a fair. It also makes it possible to change the footprint of the To reduce the size of the carousel even further, for example when entering and leaving The passengers disembark the support rods opposite their freely hanging ones The position towards the mast can be slightly deflected, and with it the outer circumference the area of the seat or gondola carrier becomes very small in the basic position.

If a support rod deflected inwards towards the mast in one Angles of, for example, 30 ° - 60 ° to the radial direction of a support arm in the Plane of the rotating beam runs, there can be a wide deflection of the support rod be made internally without the risk that the Seat support or gondola support with the central mast or its casing in Come into contact, as the seats or gondola carriers only up to Tangential direction to the mast or its casing are deflected.

The pivot axis of the support rods preferably runs in the plane of the rotating support, especially in a horizontal plane. However, it can also be provided, the pivot axis in relation to the plane of the rotary support in to arrange an angle deviating from this plane so that a Deflection of the support rods in the radial direction a corresponding advance or Backward movement of the support rod in the circumferential direction of the rotary support causes.

In a preferred embodiment of the invention, the support rod is in divided two partial rods, which are connected to each other via a swivel joint. The generated deflection of the partial rods causes the lower one over the Swivel joint attached to the upper partial rod an additional movement can run around the swivel. If the preferably freely movable Rotation axis of the swivel joint, in particular at right angles to the rotation axis of the The joint runs between the upper part of the rod and the swivel bracket Gondola carrier by swinging around the swivel one Additional movement, depending on the length ratios of the partial bars circular or oval movement of the seat and gondola beams around the ends of the Rotary carrier causes. The axis of rotation of the swivel joint is preferably one Brake device provided to z. B. a quick after the end of a journey To reach a standstill of the carousel. The braking device can by Gas springs, brake shoes, hydraulic cylinders or tension springs can be realized.

In a particularly advantageous embodiment of the invention it is provided that the pivoting of the support rods in the circumferential direction of the rotary support successive support rods in relation to the circumferential circle of the Rotary carrier is done in opposite directions inside and out. This can the seat and gondola beams at the ends of two successive ones Do not interfere with each other when swinging out the support rods, as only in each case every other support rod is deflected inwards while the one in between lying support rod is pivoted outwards. This design of the Invention has the particular advantage that the gondola and seat support very much can be arranged staggered on the circumference of the rotary support without when pivoting the support rods inwards, a mutual Touching the seat or gondola carrier of different support rods would be possible. This measure is also of particular advantage insofar as the Footprint of the carousel can be kept even smaller, though a high frequency of use is possible because practical while driving constantly the entire carousel space by alternately pivoting the Seat or gondola carrier is used inside / outside. Although the carousel to allow use similar to a chain carousel achieve additional driving experience by swiveling inwards / outwards is possible, which is not the case with conventional chain carousels is possible.

So that a recurring sequence of swivel movements after outside / inside is possible, the carousel should preferably be a couple of Have arms of the rotary support or the support rods.

The pivoting movement of the support rods can be done by mechanical Force transmission, for example cable, chain or the like, by hydraulic or Pneumatic drive or electric motor. For alternating on and The movements can be swiveled out successive support rods by a suitable control device be synchronized with each other. If a carousel has a rotating beam with only a few, e.g. B. four arms can also be used to synchronize the Swinging out of the support arms can be dispensed with. The individual support arms then have so much freedom of movement that mutual disability does not occur.

If the swiveling in and out speed to the length of the support rod is adjusted, the pivoting of the support rods according to Art realize a pendulum movement, so that the energy expenditure for one or Swinging out can be kept very low.

In a special embodiment of the invention, the input and Swiveling the support rods also on a few or alternately operated Support rods are limited.

To further increase the driving experience, it can be provided that To design the rotating beam to be raised and lowered in the vertical direction. Further the rotating support can be rotatable about an axis that is at an angle to the vertical runs, so that in addition a vertical movement of the passenger carrier or -gondolas can be reached while circulating around the mast. It is also one Shaft movement possible through a rotatable inclined axis of the rotating beam.

The seat supports or gondolas attached to the lower end of the support rods can be in total or on their own axes parallel to the axis of the support rods rotatably, if desired, also by a separate drive. It can also be provided, seat support additionally by a horizontal at rest Let the axis rotate, so that rollover movements of the seat support possible are.

Five seat supports are preferably offset in pairs by 72 ° arranged against each other at the lower end of the support rods.

In a special embodiment of the invention, the rotary support of the carousel four arms, each containing five x two seats, so that the The total capacity of the carousel for one trip is 40 people.

The invention is explained in more detail below using an exemplary embodiment. Show it:

a top view of a carousel according to the invention in the rest position, the ends of two arms of the rotary support having been omitted for better illustration.

1 shows a central mast 1, on the upper side of which a rotating support 2 is rotatably mounted. If desired, the axis of rotation of the rotary support 2 to the axis of the mast at an angle to the vertical be deflected, wherein the axis of rotation can itself be designed to rotate. Corresponding devices for changing the axis of rotation are from the stand known in the art.

In the exemplary embodiment, the rotary support has six arms 10, on the other of which Ends each of the support rods 3 hanging via a joint 8 in a fork 7 are attached. The number of rotating arms can be changed easily, e.g. B. on four. The axis of rotation of the support rods 3 is not tangent to Rotating beam, but at an angle of 30 ° - 60 ° to the tangent, so that the Swiveling a support rod leads to the pivoting plane of the Support rod runs approximately tangentially to the mast or its casing. The Support rods 3 are pivoted outward / inward by force, so that, as shown, they can experience a wide deflection to the outside, but can also make a wide deflection inwards. The Is pivoted, for example, by a cable 13 over a pulley 14 causes, which is fixed on the pivot axis 8 in the fork 7.

On the right side of Fig. 1, a support rod 3 is shown, which consists of two Partial rods, an upper part rod 5 and a lower part rod 6, which are connected to one another via a swivel joint 9. The hinge axis of the Joint 9 runs in particular at right angles to the axis of rotation 8 Support rod 3 and swivel bracket 2 and is freely rotatable. In a not shown Embodiment, it is also possible to force the joint 9 (e.g. to control certain trajectories as desired adjust.

A free movement of the joint 9 causes that when swiveling or Swinging the support rod 3, the lower part of the rod 6 swinging around Joint 9 is pivoted so that the gondola or seat support 4 when moving out or Swinging in with respect to the rotary support 2 is a circular or elliptical movement perform. The shape of the ellipse is determined by the Ratios of lengths of the partial bars 5 and 6. The free movement can also be restricted in that the joint 9 has a braking device is assigned, e.g. B. gas pressure cylinder, brake shoes or tension springs. Thereby uncontrolled commuting is minimized.

The illustration clearly shows that in contrast to a chain carousel a constant movement of the gondola or seat supports in the carousel room is achievable. Although it is also possible to move the carousel in the the support rods 3 solely due to the centrifugal force of the seat or gondola support 4th be deflected so that there is a circular movement of the seat or Gondola carrier results, is preferred according to the invention. that at the scope of the Rotary carrier 2 successive support rods 3 each in particular can be swiveled alternately inwards and outwards. If the Speed of pivoting is adapted to the length of the support rod 3, can support a natural pendulum movement, so that only the Pendulum losses are to be compensated for, so that the energy required to maintain the Panning movements are relatively small. With sufficient force can a wide pivoting of the gondola or seat support 4 outwards and inwards can be achieved, whereby the pendulum movement takes place around a circular path, which is would set due to the centrifugal force when driving.

In a further development of the invention it can also be provided that To form support rods 3 telescopically in order to change swivel frequencies enable. When the support rods are arranged on a deflectable spring the length of the support rod shortens when swiveling inwards, while it extends outward when swung out, so that a still further driving feeling effect can be caused.

Fig. 2 shows a side view of an arm of the rotary support 2 with articulated support rod. By means of a cable 13 around the pulley 14 can the pivoting of the support rod 3 are carried out. The rope guide runs around the pulley 14 and the deflection pulleys 15, 16 and the control pulley 17th Rotation of the control pulley 17 causes the pulley 14 to rotate, and thus a pivoting out of those connected to the pulley 14 Support rod 3. The control disc 17 can swing out all at the same time Cause support rods 3 on the various arms of the rotary support 2, the direction of rotation of the pulleys 14 on the rotary carrier 2 successive support arms 10 are directed in opposite directions, for example, by crossing the associated cable pull. At only few arms on the rotating support, e.g. B. four, can also on the synchronization and the coupling of successive support rods can be dispensed with.

The pivoting of the support rod 3 to the outside takes place at an angle 20. A corresponding inward pivoting can be at the same angle take place without this being absolutely necessary. To the for This is done to keep the required energy as low as possible Swing the support rods out at equal angles outwards and inwards from a rest position, which is characterized by the centrifugal force of the Support rods when turning the carousel.

Fig. 2 shows a rotary support 2, which is at right angles to the Central axis 18 of the mast 1 rotates. The rotation of the rotary support 2 can, however also take place around a fixed or circumferential inclined axis, so that during the rotation around the axis of rotation also a vertical up and down Movement of the seat or gondola support due to lifting or Lowering the ends of the arms 10 of the rotary support is possible.

The total height of the swivel bracket can also be raised.

At the lower ends of the support rods are in pairs in Fig. 2 arranged seats 11, 12 shown. These can be fixed. The However, the entire seating group can also move around the longitudinal axis of the lower one Partial rod 6 can be rotated freely or positively driven. Can also the seats can be arranged on a seat support attached to the support rod 6 and be movable individually or in groups relative to the seat support. It is it is also possible for the seats 11, 12, individually or in pairs, to face each other the lower part of the rod 6 at right angles in the rest position turn or swivel the horizontal axis of rotation, including one Overhead movement of the seats or seating groups is possible.

Fig. 3 shows a top view of a carousel according to the invention. There are six arms 10 of the rotary support 2 are shown, with a better illustration two of the ends of the arms 10 have been omitted. The figure shows that the pivoting plane of the carrying rods 3 opposite the Radial plane of the arms is deflected by an angle 19, so that an inward pivoting the support arms not through the mast 1 or its cladding is hindered. The swiveling inward must be so for safety be far restricted that the passengers when swinging out a Support rod not inward with an adjacent arm of the rotating beam Can come in contact. If the length of the support rods 3 is so short is chosen that the feet of the passengers in a pivoted support rod each case in the space between two adjacent arms of the Rotary carrier 2 remain, the pivoting inwards practically up to Horizontal level or even beyond.

Although six arms of the rotary support are shown in Fig. 3, there is point out that the number of arms is in principle not limited. If symmetrical relationships of swinging in and out are desired, however, it is preferred to provide a pair of arms. The one and Swinging out is preferably 70 ° - 90 ° compared to that through the Centrifugal force given rest position, so that in practice Swiveling outwards by about 80 ° - 100 ° and swiveling inwards by 60 ° - 80 ° to the vertical.

The control of the carousel includes an adjustment of the rotary motor Adjustment of the rotational speed of the rotary carrier 2, the adjustment of the Pivotal movement of the support rods 3 (by a fixed amount or by a adjustable value), a possible tilting of the axis of rotation of the rotary carrier 2 and a possible lifting of the rotary support 2 and any additional possible Changes in the movement of the carousel. Furthermore, the rotation the seat support can be controlled. The pivoting movement of the support rods around it Joint 9 can also be controlled. The control can be done by hand done, but it is preferably carried out under program control, wherein different program sequences can be used.

In a further development of the invention it can be provided that also in In the rest position, the support arms can be pivoted slightly inwards around the To reduce space requirements for boarding and alighting passengers. Thereby this results in a small footprint, although it has a wide swinging out in operation the seats or gondolas are possible to the outside.
