The present invention concerns a device for the realization of an ability game, with marbles to be thrown along a guide for reaching, after a round, exact locations on said guide.

The present invention represents a novelty with regard of any known game, due to the discovery of the need of impressing to a marble, linked to a gyroscopic rotation, a manual impulse that makes it reach the end of a horizontal guide ending up with a rise so that it can store the energy requested for performing the double round in retrograde motion, until it reaches apposite locations shown with colours or other, according to the intensity of the impulse and/or due to the interaction with an eventual interfering apparatus.

The advantages of the device according to the present invention consist in the possibility of realizing different games according to the dimensions of the guide, of the marbles, of the division in score areas on the marbles as well as on the guide, and of the presence of an eventual

interfering apparatus, all based on the ability and precision in throwing the marbles by the players.

The present invention will be explained more in detail hereinbelow according to the enclosed drawings in which an embodiment is shown.

Figure 1 shows an axonometric view of a complete device for an ability game with marbles on a double round.

Figure 2 shows a section of a possible structure of a marble with gyroscopic rotation on a preferential axis.

Figure 3 shows a possible structure of support for the guide for application to the wall.

Figure 5 shows an axonometric view of a variant of the device provided with an interfering apparatus with rotable drums a variant of which, provided with pins 24, is shown in figure 4.

The enclosed figures show a device for an ability game with marbles on a double round, comprising: - a plane guide 1 with double track 2 so as to represent an internal continuity solution 3

whereon a marble 4 can steadily roll up to an inclined end 5 with a terminal restraint 6 that allows marble 4 to perform a double round, in retrograde motion with respect to the impulse one;

- one or more locations 7-8, placed on the track 2, marked by different colours and/or surface, eventually braking, materials, or by alphanumerical marks, for identifying the arrival positions of marble 4 according to the intensity of the impulse and of its gyroscopic rotation and/or of provided interferences;

- one or more marbles 4 with the surface devided in two or more coloured sections or also all of one colour and/or marked with lines and/or with numbers or letters, realized with a hollow spheric structure of metal or other material with an irregular shape, so as to show a heavier anular band 14 that determines a gyroscopic restraint for the rotation with respect to the preferential axis A, perpendicular to said band that lies on guide 1, when the marbles are thrown on it.

According to the present invention, guide 1 is provided with a straight horizontal structure, but in possible variants it may have curves of any angle and inclination.

Furthermore, for making the marbles 4 suited for the throw and for a convenient sliding on track 2, the structure 13 may be externally covered with a rubber layer 15 and/or with a cloth layer 16.

Above mentioned terminal restraint 6 may be realized with springs or similar, with a blade or a spiral and the guide 1, in possible variants, may be placed onto fix supports 17 or on adjustable supports 9, resting on the floor or on shelves 10, with telescopic arms 11 that may be fixed to vertical walls.

The working of the device relating to the realization of a possible ability game, ma be described as follows:

- each player throws the marble 4, with such an adjusting of the impulse as to allow said marble to perform the run on tracks 2 up to the inclined part 5 and then to return until it reaches locations 7-8, making coincide the eventual part with the higher value of the marble with the location with the higher score on track 2 or with the same numbers or letters;

- each marble 4 thrown with the wrong impulse, may reach said locations or the collect point 12, provided on guide 1.

In a possible variant according to the present invention, said elastic means 6 may represent, when coupled with a completely plane guide 1, the return means for the retrograde motion.

In the variant shown in figure 5 the device according to the present invention comprises one or more drums 18 provided with an external surface having all the same colour or devided in parts with different colours and/or marked with numbers or letters or with symbols of other kind, that rotate on their own axis when they get into contact with the marble 4 passing by, or that may be approached by means of a mechanical transmission consisting of a lever system 20-21-22 and controlled by one or more hand grips 19, for allowing the players to perform moves for adjusting the speed of said marble and of the position of the marks on the drums.

Furthermore, the marble shown in figure 2 may also have an inter-ring of a high specific weight material or may consist of a full structure with symmetric shape but still provided with an inter¬ ring, so as to realize a gyroscopic restraint for the rotation with respect to said preferential axis A.
