Ball whirling device for recreational games of chance

摘要

The invention consists of eliminating the inner central shaft of the drum in order to allow a more homogenous mixing of the balls such that the chances of the balls being winning balls are not dependent on the position that they may occupy before the drum is rotated. To that end, the ball mixing blades (9) are integrally attached to the inner face of the structure of the drum. Not only does this structure allow mixing the balls better, but it also simplifies maintenance work on the device, in that it includes respective outer shafts (3) that are easily accessible without having to disassemble the drum in the event that the pin that links it with the mechanism for driving the rotation of the drum breaks.

1. A ball whirling device for recreational games of chance, comprising:
a drum comprising a plurality of perimetral rings, a first lateral end coupled to a first outer shaft, a second lateral end coupled to a second outer shaft, and a hole adapted to allow a ball to pass between an inside of the drum and an outside of the drum; an actuating drive system adapted to actuate the drum, the actuating drive system being connected to the first outer shaft; a sensing device adapted to sense a position of the drum, the sensing device being connected to the second outer shaft; a plurality of drawing balls disposed in the drum; a basket for displaying a winning ball, being disposed proximate the hole, such that when a particular drawing ball passes from the inside of the drum to the outside of the drum, the particular drawing ball enters the basket; and a plurality of blades disposed in the inside of the drum, the plurality of blades being adapted to mix the plurality of drawing balls, wherein each of the plurality of blades is integrally attached to a respective perimetral ring of the drum and is disposed in one of a first plane that comprises a point at a geometric center of the drum and a second plane slightly inclined with respect to the first plane.
