Abstract

The present disclosure relates to a roulette wheel apparatus, and in particular to a ball launcher for use in a gaming system such as a roulette wheel apparatus and roulette wheel apparatus comprising the ball launcher. According to a first aspect, the ball launcher comprises a pair of launch tubes adapted to be connected to the airflow generator and defining different launching directions, wherein the ball gate for gating the ball into one of the launch tubes includes a ball shuttle adapted to be moveable from a ball-receiving station to each one of said pair of launch tubes to transport the ball from the ball-receiving station to one of said launch tubes.

First claim

What is claimed is:

1. A ball launcher for launching a ball into a playing area, the ball launcher comprising:
at least one airflow generator;
a first launch tube connected to the airflow generator;
a second launch tube connected to the airflow generator, wherein the second launch tube defines a different launch direction into the playing area than the first launch tube; and
a ball gate for gating the ball into the first or second launch tube and the airflow flowing therethrough,
wherein the airflow generated by said airflow generator is controlled by an airflow controller, and
wherein the airflow controller is adapted to, when a detected ball speed is higher than a desired ball speed and/or the ball speed is to be decreased:
(i) reverse airflow direction, and/or
(ii) cause airflow in a direction opposite to the ball moving direction.

2. A ball launcher according to claim 1 , wherein said airflow controller is configured to control and/or reverse airflow in response to ball speed detected by at least one ball speed detection device in said at least one launch tube or in said playing area.

3. A ball launcher according to claim 2 , wherein said ball speed detection device includes at least two ball sensors spaced apart from each other along the ball path through the launch tube and/or in the playing area, and furthermore a speed calculator for calculating ball speed from the time difference between signals of said ball sensors.

4. A ball launcher according to claim 1 , wherein said airflow generator is adapted to provide for variable airflow mass and/or airflow speed and/or airflow pressure, wherein said airflow generator is controlled by said airflow controller which is adapted to control the power and/or the driving direction of the airflow generator in response to detected ball speed.

5. A ball launcher according to claim 4 , wherein a ball shuttle comprised by said ball gate is adapted to be moveable from a ball-receiving station to each of said first and second launch tubes to transport the ball from the ball-receiving station to one of said launch tubes, wherein said ball shuttle forms a valve adapted to partially and/or entirely open and close each of said first and second launch tubes, so said airflow controller controlling the position of the ball shuttle in response to detected ball speed provides for controlling airflow mass and/or airflow speed and/or airflow pressure in each of said first and second launch tubes, thereby controlling airflow direction and/or reversing airflow.

6. A ball launcher according to claim 5 , wherein said valve formed by said ball shuttle is adapted to reduce or shut-off airflow through the first launch tube when increasing or opening airflow through the second launch tube and/or to reduce or shut-off airflow through the second launch tube when increasing or opening airflow through the first launch tube.

7. A ball launcher according to claim 6 , wherein said ball shuttle is formed as a shuttle rotor, which is rotatably supported about an horizontal shuttle rotor axis, wherein the shuttle rotor is adapted to stop with a ball-receiving seat at a ball-receiving station positioned at about 12 o'clock when considering the shuttle rotor as a clock-face, and to stop with the ball-receiving seat at about 8 to 11 o'clock to register the ball-receiving seat with the first launch tube, and to stop at about 1 o'clock to 4 o'clock to register the ball-receiving seat with the second launch tube.

8. A ball launcher according to claim 7 , wherein said shuttle rotor forms a rotatable valve plate including a through hole for receiving the ball, wherein the launch tubes have endings facing said valve plate at a path along which the through hole is moveable.

9. A ball launcher according to claim 5 , wherein the launch tubes extend from opposite sides of the ball shuttle to define launching directions opposite to each other.

10. A ball launcher according to claim 1 , wherein the airflow controller includes a calibration and/or self-adaption component for effecting calibration and/or self-adaption of airflow in response to a plurality of values of ball speed determined repeatedly in different launching processes.

11. A ball launcher according to claim 1 , wherein said launch tube providing for an obstacle-free, non-stop passage for the ball from the ball gate into the playing area.

12. A ball launcher according claim 1 , further comprising a feeding tube for feeding a ball from the playing area to the ball gate, said feeding tube having an inlet to be positioned directly beneath the playing area, wherein said feeding tube provides for a vertical ball path from said feeding tube inlet to said ball gate to allow said ball to directly fall from said playing area into said ball gate.

13. A roulette gaming system comprising:
a playing area comprising a roulette wheel, wherein at least a portion of the roulette wheel is moveable to form a ball discharge opening; and
a ball launcher comprising:
an airflow generator;
a first launch tube connected to the airflow generator;
a second launch tube connected to the airflow generator, wherein the second launch tube defines a different launch direction into the playing area than the first launch tube; and
a ball gate for gating the ball into the launch tube and the airflow flowing therethrough,
wherein the airflow generated by said airflow generator is controlled by an airflow controller, and
wherein the airflow controller is adapted to, when a detected ball speed is higher than a desired ball speed and/or the ball speed is to be decreased:
(i) reverse airflow direction, and/or
(ii) cause airflow in a direction opposite to the ball moving direction.

14. The roulette gaming system according to claim 13 , wherein the first and second launch tubes are arranged to have exits extending in substantially opposite directions tangential to a bank path of a roulette bowl comprising the roulette wheel.
