Description: Random generator and kit for it

The present innovation relates to a random generator for determining a colour, number or sequence thereof, in particular the numbers 1-6 on a dice, which is determined by playing and arranging a certain number of individually and/or in pairs differently coloured or numbered balls.
further on a kit for it.

Such "mechanical random number generators" are known from the drawing of lottery numbers. In contrast to electronic random number generators, the drawing of the individual balls or numbers and the order of the drawn, differently numbered balls are carried out in a way that is understandable to everyone by mechanically mixing a certain number of numbered balls held in a hollow ball and then playing a certain number of the balls held in accordance with the given mathematical probabilities. However, these well-known random number generators are quite complex in their construction, with the balls being drawn fully automatically in order to completely rule out any influence from human handling.

The innovation is therefore based on the task of developing such a mechanical random number generator, in which a

·

Determination of the order of numbers or colors by drawing individual balls or their arrangement, to be modified in such a way that simple manual handling of the random generator for mixing the balls and for drawing them is possible, whereby the random generator can also be manufactured cheaply with as few and simple means as possible.

It should preferably be possible to change the random possibilities, for example by exchanging or adding the balls to be used.

To solve this problem, the design of a random generator of the type mentioned at the beginning is provided according to claim 1. A hollow sphere is used, made up of two half-shells that can preferably be detached from one another, which, if the size is suitable, can easily be grasped by hand and rotated or swiveled, so that with this movement of the hollow sphere, balls lying in the hollow sphere-shaped lower half-shell rotate in a circular path on the hollow sphere-shaped curved inside of the two half-shells and, after this mixing, reach the area of the lower vertex of the hollow sphere, whereby a certain random arrangement results among the balls when they are at rest. In the resting state, this always results in a "ball packing" in which one ball is in the center, around which the others are grouped in a circle, so that certain arrangements can be distinguished from one another.

Alternatively, it is intended that the random arrangement is not carried out in the area of the lower vertex of the ball but near the upper vertex, with a permanent magnet arranged in the upper vertex, which groups the balls to be played one after the other in a specific random arrangement on its underside.

Balls made of a magnetically attractable material (e.g. iron) are brought one after the other from a circular hole arranged in the lower vertex of the ball onto a parabolic path below the permanent magnet by applying a finger, whereby the balls that reach the upper vertex are attracted by the permanent magnet, provided that the vertex of the parabolic path is below the permanent magnet. It is therefore possible to arrange several balls specifically below the magnet when the parabolic paths of the balls to be played are set one after the other in this way and to play a desired group of numbers.

Claims 2-13 relate to advantageous embodiments of such random generators.

The innovation is described in more detail below using 6 different embodiments with reference to their drawings.

The drawings show:

Figure la : One made of two transparent hemispheres

A hollow sphere consisting of two plastic half-shells, the inside of which is hollow-spherical and smooth except for a circular hole in the lower vertex of the wall of the lower half-shell, in which a ball that protrudes outwards and inwards can be secured against movement of the outer hollow ball, with the hollow ball also containing 4 differently colored, equally sized pairs of balls, which, when the hollow ball is at rest, form a ring around the ball that is in the circular hole and has a thicker outer diameter,

Figure Ib : A random generator consisting of a

Hollow sphere according to Figure la with a circular hole in the shell of the lower half-shell, whereby in contrast to Figure la the sphere with a thicker outer diameter and fixed in the circular hole is no longer surrounded by 4 pairs of spheres but by 8 identical smaller, differently colored individual spheres in the resting state, whereby a state after pivoting the hollow sphere to mix the sphere is shown, in which two spheres still orbit on a circular path on the lower and upper half-shell;

Figure lc : A modification of the random generator according to

Figures la and lb, whereby in the hollow sphere according to this embodiment, smaller balls of the same size and different colors are now received in the downwardly turned upper half-shell without a circular hole 7 in the outer diameter and mixed there, and collect in the area of the lower vertex of the hollow spherical curved inside of the half-shell and the 6 remaining balls are placed around a central ball;

Figure 2: A fourth embodiment of the random generator, in which a short cylindrical rod-shaped permanent magnet is mounted centrally in the area of the upper vertex of the upper half-shell, which extends downwards into the hollow sphere, and opposite this, in the lower vertex of the lower half-shell, a circular hole is mounted in the wall there, which is slightly smaller in inner diameter than the balls of the same size made of a magnetic material accommodated in the hollow sphere;

Figure 3 : A fifth embodiment of the

Random generator, consisting of two transparent semicircular plastic half-shells of the same size, put together to form a hollow sphere, whereby, in contrast to Figures la, Ib and Ic and Figure 2, neither the upper nor the lower half-shell has a circular hole and balls of the same size are played in the hollow sphere

which are differently colored, and

Figure 4 : A sixth embodiment of the random generator, consisting only of a
lower half shell with the 7 equal-sized balls inserted there as shown in Figure 3, where
this half shell is open at the top.

The random generator 1 according to Figure la consists of two hemispherical half-shells 13, 14 of equal size, which are connected to form a hollow sphere 15 by edge flanges 17a, b which are attached to their upper peripheral edge and can be placed one on top of the other. The hollow sphere consists of a clear, transparent plastic material, so that the balls 7; 8a, b; 9a, b; 10a, b; 11a, b inserted there are visible from the outside. The half-shells 13, 14 are also curved and smooth on their inner sides 16a, b in the shape of a hollow sphere, so that when the hollow sphere 15 is pivoted and rotated, eight of the nine balls inserted there rotate freely on circular orbits. At the lower vertex of the lower half-shell 13, a circular hole 12 is provided, which has an inner diameter such that the ninth ball 7, which has a slightly larger outer diameter and is thicker than the other eight balls, can be inserted and fixed there with one section.

The thicker ball 7 has an outer diameter of 1 cm, while the remaining 8 smaller balls have an outer diameter of 0.6 cm. The inner diameter of the circular hole is 0.9 cm. The outer diameter of the thicker inner ball is selected in relation to the number and outer diameter of the smaller balls 8a,b; 9a,b; 10a,b; 11a,b in such a way that the smaller balls are distributed around the thicker ball in the form of an outer ring when at rest.

The eight smaller balls are each designed as four pairs of balls, whereby, for example, the balls 8a,b of a pair not only have the same size and weight but also the same color, i.e. they are identical in terms of material, dimensions, weight and color.

Since the inner sides 16a,b of the half-shells 13,14 are completely identical except for the circular hole 12 in the area of the lower vertex of the lower half-shell 13, the white, red, blue and yellow colored ball pairs are played out in the hollow ball with equal probability, whereby the two balls of a ball pair must be arranged directly next to each other on the outer circumference of the thicker ball 7.

Depending on the number 1-6 of a dice, a

The numbers 1 to 6 are drawn as follows:
white ball pair: valued number 1

red ball pair: valued number 2

blue ball pair: valued number 3

yellow ball pair: valued number 4

Arrangement of 2 pairs of balls
at the same time on the outside

the thicker ball: valued number 5

no arrangement of a pair of balls: valued number 6.

Since the half-shells 13, 14 can be detached from one another at their superimposed edge flanges 17a, b, the balls inserted into the hollow ball 15, in particular the middle thick ball 7, can be removed and replaced, so that the chance of randomness can be varied by arranging a thicker middle ball and a larger number of ball pairs.

The random generator 2 shown in Figure 1b *wVi*s t* a hollow ball 15 according to Figure la, consisting of two half-shells 13,14. In the lower half-shell 13 there is also a circular hole 12 in which the ball 7, which has a slightly thicker outer diameter, can be fixed. In addition to this ball, instead of 4 pairs of balls, 8 balls with a smaller outer diameter are inserted, which are identical in shape, material, dimensions and weight, but have a different color or a different number on the outside. These balls are arranged in a circle around the ball 7, which has a thicker outer diameter, in the resting state, as in the random generator 1 in Figure la, resulting in a certain order of the arrangement of the colors or numbers on the outside of the balls and thus a certain value number.

The random generator 3 according to Figure 1c again consists of the two half-shells 13, 14, whereby the lower half-shell 13 with the circular hole 12 in the area of the lower vertex is now turned upwards and the half-shell 14, which has no hole on the inside 16 b and is completely smooth, is located at the bottom.

As an alternative to the arrangement of the thick ball 7 and the ball pairs 8a,b;9a,b;10a,b;lla,b or the eight different balls 18-25 according to the random generators 1,2 of figures la,b, only seven balls 26,27,28, 29,30,31,32 of the same size are now introduced, which in turn are made of the same material and have the same weight, but each have a different color or numbering on the outside. The arrangement of a thicker ball does not take place here, since the balls are played out on the smooth inner side 16b of the half-shell 14, which is now arranged downwards. If the balls are again to be played out according to the random generators 1 or 2 of figures la or 1b,

··

the half shell 13 is turned downwards again and the ball set is replaced accordingly.

Figure 2 shows a fourth embodiment of a random number generator 4, in which a hollow sphere 34 is again formed from two hollow spherical half-shells 33, 33 ¹ made of transparent plastic material. The lower half-shell 33 has a circular hole 36 in the area of the lower vertex, while opposite in the upper vertex of the upper half-shell 33 ¹ a cylindrical rod-shaped permanent magnet 37 is arranged, which projects downwards into the hollow sphere towards the front. The inner sides 35a, b of the half-shells 33, 33 ¹ are otherwise curved in the shape of a hollow sphere and are smooth, with balls located on the lower half-shell rotating on a circular path on the inner side 35a there when the hollow sphere 34 is rotated and pivoted. Of the eight balls 38-45 of the same size, made of the same material and of the same weight, the balls 44, 45 are shown rotating on a circular path around the lower half-shell, while the balls 39-43 are shown attracted by the permanent magnet 37 on its lower front side. The balls 38-45 are each made of steel or another material that is attracted by the permanent magnet 37. To play the eight balls 38-45, they are inserted one after the other into the circular hole 36 in the lower half-shell 32, with the outer diameter of the balls being measured compared to the inner diameter of the circular hole 36 in such a way that the balls protrude approximately halfway out of the shell of the hollow ball. Since the balls lie loosely within the circular hole 36, they can be struck into the interior of the hollow ball 32 with the index finger of one hand, while the hollow ball can be held with the other hand or with both hands at the same time. The ball can receive such an impulse that it is pushed upwards into

a parabolic path, with the upper vertex of the parabolic path running directly below the front surface of the permanent magnet 37.

At this moment, the magnetic force of the permanent magnet 37 is so great that the ball is attracted to this upper apex of its trajectory and cannot fall back down into the lower half-shell 32. In this way, as shown in Figure 2, five balls 39-43 and finally the ball 38 from the circular hole 36 and the balls 44 and 45 circling on the waiting track on the inside of the lower half-shell 32 are finally attracted below the front surface 53 of the permanent magnet 37. To attach the permanent magnet 37, an adhesive connection can be provided opposite the inside 35 b or a plug-in device, whereby in an embodiment not shown, a receiving hole is created in the wall in the area of the upper apex of the half-shell 33 ¹ , into which the permanent magnet 37 can be inserted with a projection.

The value numbers can be determined based on the number of balls of the same or different colors attracted by the permanent magnet in a certain time, or by introducing pairs of balls of the same color in accordance with Figure 2 according to the number of pairs of balls attracted. For the mere playing of a number sequence, the order of the attracted, differently colored or differently numbered balls is decisive.

In the random generator 5 according to Figure 3, a hollow sphere 48 is formed from two transparent semicircular plastic half-shells 46-47, which have a completely smooth, flat inner side, i.e. no circular hole in the lower or upper half-shell. According to

- 10 -

Figure lc seven balls 26-32 of equal size and weight are introduced, which finally collect in the resting state of the hollow ball in the area of the lower vertex of the lower half-shell 46 in such a way that one of the seven balls is in the middle, while the other six balls are arranged in a ring around it on the outside. The balls have a different color or different numbering, whereby the ball in the middle of the ring, for example, determines the value number to be played, whereby, for example, a red ball lying there, which is assigned the value number 2, thus determines the number played "2".

The random generator 6 according to Figure 4 represents a simplified embodiment of the random generator 5 according to Figure 3. Only the lower half shell 46 is provided, with the balls 26-32 being played with the top of the half shell 46 open.

In all embodiments of the random number generators, the balls introduced are mixed by moving the hollow ball or lower half-shells, whereby in the later resting state of the balls in the area of the permanent magnet or the lower vertex of the half-shell held downwards, the respective random arrangement of the balls corresponding to a certain value number is established.
