Abstract

The inventive leisure sports equipment has a track in the form of two tubular running rails (3, 4) which have a circular cross-section and on which vehicles with bearing wheels are supported. The running rails (3, 4) are kept at an exact mutual distance from each other by supports (2), said supports running crosswise and being supported by stands (1). Claw feet (10) are provided on the undersides of the stands (1) for supporting them on the ground.

Description

BACKGROUND OF THE INVENTION The present invention relates to a sports entertainment device with at least one vehicle moving under gravity on a downwardly running track, the speed of which is individually controlled by the driver.

BACKGROUND OF THE INVENTION

A similar such sports entertainment device is exemplified in US-A-4,417,740. The track of this device is formed by an upwardly open groove in which vehicles can travel and in which transverse to the main direction of the groove the curvature will prevent it from leaving the track.

A sports entertainment device as described in the above-mentioned US-A4.417,740 requires relatively relative to its travel path. a lot of space. From the safety point of view, it has the disadvantage that, at high speed and with inappropriate weight distribution of the user of the sports entertainment device, the vehicle can still get out of the groove, which can lead to serious injuries to the driver and damage to the vehicle. In addition, the vehicles must be driven at a considerable distance, since at an affordable cost it is not possible to carry out automatic braking at a dangerous approach on the basis of different vehicle speeds.

In fixed places, so-called caterpillar tracks are commonly used, in which vehicles are seated and guided on transport rails. Such leisure facilities allow vehicles to run closely behind each other and allow for automatic braking if necessary, but their construction is very expensive, so that leisure-time sports facilities built on the track-like path have not yet been built on mountain slopes to allow longer downhill runs slopes. In addition, the railroad vehicles cannot be braked individually.

SUMMARY OF THE INVENTION It is an object of the present invention to provide, as simple as possible, a sports entertainment device of the type initially mentioned which is suitable for building on mountain slopes while minimizing interference with nature and without compromising user safety. of this sports entertainment device.

SUMMARY OF THE INVENTION

This problem is solved according to the invention in that the track consists of two track rails formed as tubes on which the vehicle is supported by the load wheels or skis, the tubes being kept at a precise distance from each other by the transverse running bodies supported by the stands and the stands are equipped with foot feet on their underside to support the ground.

Such carriageway made up of two parallel tubes as driving ^{1 '1} I rails can be easily prekladaná alternating falls and bends while cornering is very easy to be specific vertical outer rail turns. When the load wheels or skis do not touch flat treads flat, but are supported in cross-section by circular tubes, there is only linear contact, which makes the load wheels turn very easily, or skis easily slide, and there is no jamming because the running rails they may not have the treads constantly aligned with the load wheels or skis. Since the racks are supported by stands, the sports entertainment device only needs to touch the ground with feet with feet, so that, for example, the grass surface beneath the device will be damaged only slightly. It should also be pointed out that the latest sports entertainment device according to the invention does not need concrete foundations or other permanently anchored concrete parts. At a slight incline, it is sufficient if the sports entertainment device is laid only loosely on the ground, while in the case of larger gradients it can be additionally secured with several individual wedges into the ground.

Vehicles could also use the running rails for guidance. However, there could then be problems with the location of the guide arrangement and the brakes. This can be avoided according to another feature of the invention when between the running rails the support bodies are provided with two guide rails running parallel to the running rails and when the vehicles are provided with guide arms projecting downwards between the guide rails, which are always L-shaped and under one guide rail.

Individual vehicle braking means are particularly simple and effective when vehicles on each side above each guide rail always have braking arms with friction surfaces directed towards the respective guide rail, and when vehicles always include a brake actuator for shifting the braking arm with the friction surface from above against the guide rail. Such a brake does not act, as is generally the case with vehicles, via the load wheels, so that the user is not reliant on braking

I _f >

for slight friction between the load wheels and running rails.

The brake is particularly simply designed when, according to a further feature of the invention, the brake arm is pivotally attached to the vehicle chassis by the brake driver and the brake actuator has a U-shaped brake caliper pivotally mounted on the chassis, the upwardly projecting part of the brake arm always forming a brake and a guide arm articulated on the braking arm at the side opposite to the brake lever.

The brake acts as a gripper by its brake shoes encircling the guide rail from above and below like a disc brake and clamping it between each other when, according to another feature of the invention, the lever ratios at the brake control are sized to lift the vehicle from the rails and press the horizontal part of the guide the arms from below against the guide rail. Very good braking properties on wet rails can be achieved by different friction surfaces in the horizontal parts.

287 / B

Since the rails stand on the stands according to the invention, they can run at a considerable height above the ground. This can lead, in particular to bends, to the risk of accidents or injury to persons not adequately secured by the safety belts in the vehicle if such persons fall out of the vehicle. Dropping from a dangerous height can be ruled out reliably and with simple means if, according to a further feature of the invention, C-shaped brackets are placed on the support bodies to fasten the safety nets running along the track so that the yoke base extends horizontally and adheres to the respective support body and C The cat was above the supporting rails.

In the event of failures, the truck can be left without danger even where the running rails run relatively high above the ground if C-shaped yokes are provided to support the footbridge running along the runway.

Excessively high vehicle speeds can be forcibly eliminated by providing the load wheels with a drum brake which actuates the forced forces by means of a centrifugal force at a specified number of load wheels.

The vehicles also move in tight turns without much friction loss when the front axle load wheels are supported to a certain extent by a vertical axis located in the direction of travel ahead of the load wheels.

This swinging suspension of the front load wheels is extremely simple to carry out when, according to a further feature of the invention, the load wheels of the front axle are each mounted in a fork which is fixed in front of the load wheel in a rotatable manner in the bearing bag about a vertical axis.

According to a further feature of the invention, the individual vehicles are each equipped with a self-boosting brake. In this way, sufficiently slow deceleration values can be achieved even with relatively small force effects on the brake lever and with wet guide rails.

287 / B

The desired self-reinforcement can be realized with low construction costs such that the brake arms are connected, seen in the direction of travel, to the vehicle chassis by means of a transversely aligned driver. Here, the applied braking force also acts in the direction of pressing the braking surface, thus facilitating braking, which is particularly advantageous for wet guide rails.

The braking devices of the carriages of the sports entertaining device of the present invention should be designed such that the car-free car is independently braked. This can be realized in a simple manner if, according to a further feature of the invention, the brake lever is provided with a guide bent forward and a spring engages in the guide, which is fixed at the other end to the chassis and thus tensiones the braking device by the brake lever. This solution shortens the lever arm, which engages the spring on the brake lever when releasing the brake, so that undesirable forces are not required to release it.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a stand 1 having a support body 2 shaped as a C-shaped support plate. This carries a guide rail 5, 6 running parallel to one another in cross section, and at the free ends of its C-eye, a support rail 2, 6. is connected by struts 7, 8 to a foot plate 9 which is supported by foot feet 10 on the ground. Further struts 11, 12 extend in the longitudinal direction to a previous or next stand (not shown). One strut 13 reinforces the stand 1 in a diagonal direction.

On the support bodies 2, the C-shaped yoke 27 is fastened so that its opening faces upwards and its base extends horizontally. This yoke 27 is used to fasten a retaining net (not shown). Further, on it lies a footbridge 28, which can be formed from simple thick plates.

Figure 2 shows a comparison with Figure 1 on a larger scale the carrier body 2 of the running rails 3,4 and ¹ guide rails 5, 6, from the vehicle 13 is shown '' II _w chassis 14, and two supporting wheels 15, 16, the axes 17, 18 are aligned V-shaped so that the support wheels 15, 16 are supported from them on the running rails 3, 4 at an angle. A guide arm 19, 20 extends from the chassis 14 on each side of the vehicle forwards and backwards from the inside along each of the guide rails 5, 6 downwards, which always extends by the horizontal pin 21 below the guide rail 5, 6. Above the two guide rails 5, 6, a respective friction surface 22, 23 can be recognized, which can be moved against the guide rails 5, 6 in a manner that will be explained to further brake the vehicle 13. For automatic braking of the vehicle 13 at too high speeds, the support wheels 15, 16 are provided with a drum brake 33 which is forcibly controlled by centrifugal force.

In Figure 3, a brake arm 24 carrying a friction surface 22, 22a can be recognized under the chassis 14 of the vehicle 13. This brake arm 24 is pivotally attached to the chassis with the brake conductors 25, 26 and can be operated via the brake control 29. Here, the brake control 29 has on each side of the vehicle a brake lever 30 pivotable about transversely to the vehicle 13 running axis 32,

287 / B

Ί which is also articulated to the guide arm 31 on the brake arm 24. If the brake lever 30 rotates forward from the position shown in Figure 3, then the guide arm 31 rotates clockwise to raise the brake arm 24, thereby guiding to release the friction surfaces 22, 22a from the guide

1 and 2. In the brake position shown in FIG. 3, the brake arm 24 is shifted down so far that the friction surfaces 22, 23 from above abut the guide rail 5 shown in FIG. 2 and the guide arm pins 21. FIG. 19 pushes from below against the guide rail 5, so that it is stuck for braking as in ticks.

Figure 4 shows an additional embodiment of the vehicle 13. Here it can be seen that the brake actuator 29 is formed as an arched arm and has a brake lever 30, 30a on each side of the vehicle. Furthermore, the rear wheels 34, the rear wheels 34 and the rear wheels 15a, as well as the front axle 35 of the vehicle 13 can be seen.

Figure 5 shows that the front axle 35 on both its outer sides always has a bearing bag 37, 38, in which a fork 40 on which the load wheel 16 or the load-bearing wheel 16 is mounted is pivotably mounted about the vertical axis 39. 15a.

Figure 6 shows the chassis 14 of a vehicle 13 with a brake arm 24 which is coupled to the chassis 14 via obliquely aligned conductors 41, 42. The brake lever 30 is rotatably mounted about a pivot point 47 of the chassis 14 and connected via a clutch 43 to the conductor 42. the brake lever 30 moves anticlockwise, then the clutch 43 of the driver 42 rotates clockwise, whereby the brake arm 24 moves parallel to one another against the guide rail 5, and thus braking occurs.

The actuation of a particular brake arm 24 by the brake lever 30 can also be effected in other ways, for example by directing the clutch from the brake lever 30 directly to the brake arm 24.

287 / b

Importantly, the wires 41, 42 point obliquely forward, with an angle of not more than 45 ° to the chassis as necessary. Owing to this obliquely extending conductor 41, 42, a self-reinforcing effect occurs. If the vehicle 13 moves to the right and will be braked, then the friction torque t1 I tends to press the brake arm 24 by a drag force on the guide rail 5.

Figure 6 further shows that the brake lever 30 is tensioned by a spring 44 into the braking position. This spring 44 is fixed at one end to the chassis 14 and rests at the other end on a pulley 45 on the guide 46 of the brake lever 30. This guide 46 is fixed to and the arc extends in front of the brake lever 30 and the arc extends through the pivot point of the brake lever 30. By this solution of the guide 46, the point of action of the spring 44 on the brake lever 30 moves the further in the direction of the turning point 47, the more the brake lever is pressed forward. Thus, the spring 44 can act with the maximum lever arm on the brake lever 30. when the brake lever is released, it is less likely to act on the brake lever 30 as the brake lever 30 moves forward because the point of action of the spring 44 moves to the pivot point. Therefore, no great forces are required to hold the braking device in the release position.
