BACKGROUND OF THE INVENTION
This invention relates to an apparatus for mechanically composing a mosaic
pattern formed by balls.
Games consisting of sets of differently coloured balls, intended to be
disposed on a usually perforated composition table in order to form mosaic
patterns thereon, are well known and widely used. Up to this time,
however, the compositions had to be carried out manually by selecting the
desired balls the one after the other from a box and then suitably
disposing the same onto a composition table.
SUMMARY OF THE INVENTION
It is an object of this invention to give new attraction features to the
referred type of game, by providing an apparatus intended to allow the
composition of mosaic patterns to be carried out with the aid of
mechanical means for the selection of the balls to be inserted and their
insertion into the preselected locations of the mosaic patterns being
formed.
Another object of the invention is to provide an apparatus performing the
herinabove described operation, capable of stimulating and developing the
readiness of perception, decision and physical reaction of the player.
These objects are attained, according to this invention, by means of an
apparatus for mechanically composing mosaic patterns formed by balls,
which comprises in combination: an inclined composition table having
uniformly spaced protruding guides which subdivide said composition table
into a number of columns extending along the direction of the lines of
maximum slope of the composition table, each column having a width
slightly larger than the diameter of a ball and a length equal to at least
several times said diameter; a store of differently coloured balls to be
disposed into the columns, situated at a level higher than that of the
composition table; a reservoir of discharged balls, situated at a level
lower than that of the composition table; a launching device actuable in
order to launch each ball arriving from the upper store along a trajectory
transversal relative to said columns of the composition table; a column
forming device actuable to deviate each launched ball from its transversal
trajectory, in register with a preselected column of the composition
table, thus introducing said ball into said column; a retaining device
situated at the lower end of the columns of said composition table for
normally keeping within said columns, one on the other, the balls
contained in each column, and neutralizable in order to let said balls
descend towards the lower reservoir; a rejection device which opens into
the lower reservoir actuable in order to exclude some undesired balls from
the formation into columns; and a passageway for the transfer of balls
from the lower reservoir to the upper store.
Thanks to these characteristics, the balls which arrive one at a time to
the launching device from the upper store, in an orderly manner but with a
casual succession of their different colours, may be individually treated
by addressing them to one or another column of the composition table, or
by excluding them from the composition and directing them to the lower
reservoir; and the balls directed towards each column of the composition
table result in being disposed one on the other in the same order in which
they have been introduced, thus allowing, through a suitable choice of the
addressing imparted to the successive balls as a function of their
colours, to form on the composition table a desired mosaic pattern.
The casual presentation of the balls of different colours, and the rapidity
with which they may be disposed into columns by actuating the launching
device and the column forming device, result in being very stimulating for
the player, since they require from him a perception of the colour of the
ball which presents itself ready for being launched as well as of the
colours of the following balls, an evaluation of the column towards which
a ball having a particular colour may be directed, or alternatively the
opportuneness of rejecting that ball thus excluding the same from the
formation into columns, the consequent control of the column forming
device and finally the actuation of the launching device, all these
operations being performable very rapidly in the correct manner only on
the condition that the player is endowed with exactness and readiness of
perception, decision and reaction, and with an adequate coordination of
his movements, all these qualities becoming competitively developed by the
game.
Especially the already experienced player, who has learnt taking into
account the order with which the balls pass from the upper store to the
launching device, and is therefore in a condition to foresee in which
order he will have at his disposal the balls of the different colours, can
develop a tactical evaluation of the opportunities of disposing the balls
in the various columns to obtain with the minimum number of rejections in
the desired pattern, thus attaining even very high composition speeds made
possible by the launching rhythm, which may reach, for example, the
frequency of 6 balls per second. Moreover, the game advantageously
develops the coordination of the movements of both hands, owing to the
need for controlling simultaneously, one by each hand, the launching
device and the column forming device, respectively. The amusement and the
possible competition, resulting from a clever management of the game,
advantageously stimulate the development and coordination of the
psychomotorial activities of the player.
Preferably, the upper store for the balls is formed by a flat region
delimited by a suitably inclined lower wall through which opens a mouth of
the launching device, and it has no wall extending convergently relative
to said lower wall, so that the balls contained in the upper store rest
against each other and against the lowest ball engaged within the
launching device, and roll down in an orderly manner one at a time into
the launching device without giving rise to cloggings.
Preferably, the column forming device comprises a plurality of deviation
means, each of which corresponds to a column of the composition table, and
a corresponding plurality of control means, each of which is marked in
conformity with that column of the composition table to which the
activation of the relevant control means gives access.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
The apparatus shown in the drawings comprises a box-like body 20 which may
be molded of plastics and is frontally closed by a cover 28 of transparent
plastics, connected to the body 20, for example, by means of elastic
snappy rivets 30. Inserted between the box-like 20 and the transparent
cover 28 there is a rigid sheet 31, for example of cardboard cut by means
of a hollow punch, which defines a rolling plane for the balls.
The box-like body 20 is dorsally provided with joints 21 to which there are
connected legs 29 capable of assuming an activity position and a
neutralized position. In the activity position (FIG. 2), the free ends of
the legs 29 and the lowest dorsal edge 23 of the body 20 may rest on a
plane P, for example of a table, thus maintaining the box-like body 20 in
an inclined position to which corresponds the condition of use of the
apparatus. The value of the slope is chosen, also as a function of the
materials used, so as to generate an appropriate rolling speed of the
balls used for the composition. In the neutralized position (FIG. 3), the
legs are approached to the body 20 and allow the apparatus to be put away
with a reduced encumberment.
In the embodiment shown, the legs 29 are articulated by means of slots on
flattened pivots 22 formed on the joints 21, about which the legs can
rotate to reach the neutralized position, whereas in the position of
activity they can be slightly inserted into the joints 21, thus engaging
the flattened pivots 22, whereby they can no more rotate and ensure the
bearing stability until they will be pulled towards the outside in order
to allow rotating them and bringing them back to the neutralized position.
Mounted within the box-like body 20 there is a composition table 38,
preferably made of transparent plastics, which has a series of protruding
rectilinear parallel and uniformly spaced guides 39 disposed along the
lines of maximum slope of the body 20 when this latter is in the condition
of use, and a transversal wall 40 extending at the upper end of the
protruding guides 39. These latter subdivide the composition table 38 into
a number of parallel columns which have a width slightly larger than the
diamter of the balls intended to be used for the formation of the mosaic
pattern, and a length corresponding to several times the diameter of said
balls.
A lower and lateral portion of the body 20, not covered by the rolling
plane 31, forms a lower reservoir 24 for reserve balls A, which are of
different colours. The whole thickness of the box-like body 20 is utilized
for this reservoir, thus obtaining, yet with a reduced encumberment
surface, a reservoir of a sufficient capacity. Protruding walls, formed on
the transparent cover 28 at its face turned towards the box-like body 20,
delimit on the rolling plane 31 different regions, namely: an upper store
32 for balls B to be disposed into columns, a rejection passageway 33
extending from the upper part of the apparatus up to the lower reservoir
24, a launching passageway 35 which communicates with the lowest point of
the upper store 32 through a mouth 34 and extends along the transversal
wall 40 of the composition table 38, a return passageway 36 which from the
end of the launching passageway 35 descends sideways the composition
table, passes along its lower edge and opens into the lower reservoir 24,
and finally a wide charging passage 37 connecting the lower reservoir 24
to the upper store 32.
The upper store 32 is delimited by an inclined lower wall 32' through which
opens the mouth 34 of the lauching passageway; all the balls B contained
in the store rest on the lower wall 32' and on the lower ball engaged in
the mouth 34, thus spontaneously arranging themselves in an orderly way in
superimposed rows. The store 32 has no delimitation walls towards the
charging passage 37, and this characteristic prevents during the feed of
the balls any possibility of clogging, which unavoidably would occur with
a usual hopper-like configuration. Moreover, the store 32 has wall
sections 32" opposite the lower wall 32', which sections extend along a
direction parallel to this latter, and lateral wall sections 32.degree.
inclined at 60.degree. with respect to the walls 32' and 32", so that the
outline of the store reproduces the spontaneous arrangement of the balls
contained therein, thus utilizing to the maximum degree the space and
favouring an orderly arrangement of the balls. In the illustrated
embodiment the two wall sections 32" opposite the lower wall 32' form a
step whose height is equal to that of the ball rows, in order to increase
the utilization of the space without disturbing the regularity of the
arrangement of the balls.
The slope of the lower wall 32' relative to a horizontal line of the
rolling plane 31 is chosen, also as a function of the materials used and
the slope of the body 20 is the condition of use, in such a manner that
the balls B contained in the store 32 will rest the one on another with a
sufficient stability, and will tend to roll regularly, row by row, towards
the mouth 34 as the balls are withdrawn from the store through said mouth.
The slope shown in the drawing is suitable, in the exemplified conditions,
when the rolling plane 31 is made of metallized cardboard and the balls
are made of plastics.
The mouth of the rejection passageway 33 is situated in front of the mouth
34 of the launching passageway 35 and normally it is occluded by a tab 42
formed on a lever 41 (FIG. 6) pivoted on a pivot 25 of the box-like body
20 and provided with a rejection control pushbutton 43. A return spring 44
maintains the lever 41 and its tab 42 in a position occluding the mouth of
the discharge passageway 33. The pushbutton 43 projects from the cover 28
and may be pressed in order to temporarily displace the tab 42 so as to
stop it from occluding the discharge passageway 33. By this operation the
balls B situated in the upper store 32 are allowed to roll by gravity, the
one after the other, through the rejection passageway 33 towards the lower
reservoir 24, as long as the pushbutton 43 is kept lowered.
The launching device is installed at the mouth of the launching passageway
35. The launching device comprises a launching member 46 and a retaining
member 47, both of them being supported by a lever 45 (FIG. 4) pivoted on
a pivot 26 formed on the box-like body 20. Lever 45 has an operation arm
48 which terminates in an elastically flexible member 49 forming a return
spring which normally maintains the lever 45 in the position shown in FIG.
4. In this position the members 46 and 47 are positioned at the two sides
of the mouth 34 of the launching passageway 35 and retain a ball C which,
being situated at the bottom of the upper store 32, has penetrated by
gravity into the mouth 34. Resting on the operation arm 48 of the lever 45
there is a tappet end 51 of an operation lever 50 (FIG. 5) pivoted on a
pivot 27 formed on the box-like body 20 and provided with a control
pushbutton 52. Pushbutton 52 projects from the cover 28 and can be
pressed, or rather struck, to lower the lever 50 and thus make oscillate
the lever 45 against the action of the spring 49. By this operation the
retaining member 47 is made to disappear below the rolling plane 31,
whilst the launching member 46 advances and imparts a pulse to the ball C,
thus making it roll along the launching passageway 35. If the ball is not
intercepted, it reaches the end of the launching passageway 35 and enters
the return passageway 36, thus returning along this latter to the lower
reservoir 24. This operation serves to exclude from the column formation
the balls which are not intended to be used, and furthermore, in this way,
the balls which, in consequence of any error whatever, have not been
disposed into columns are recovered and reintroduced into the reservoir
24.
Operation lever 50 acts with a considerable multiplication, so that a short
stroke of the pushbutton 52 is sufficient for imparting to the lever 45 a
pulse capable of launching the ball. This fact facilitates the use of the
apparatus, in consideration of the fact that the pushbutton 52 has to be
struck many times during each composition, and also aids launching the
balls in a rapid succession
The column forming device is located between the composition table 38 and
the bottom of the body 20; it comprises a number of column formation
levers 53, one for each column of the composition table. Each column
formation lever 53 (FIG. 7) is pivoted on an elastically yielding support
57 applied onto the box-like body 20 and is subjected to the action of a
return spring 58 which normally retains the lever in the position shown in
FIG. 7. Each lever 53 has a deviation tab 54 which, in the rest condition,
is situated between the rolling plane 31 and the bottom of the body 20, in
register with launching passageway 35 (but without projecting into this
passageway), and at a greater distance from the transversal wall 40 of the
composition table 38 than from the opposite wall of the passageway 35.
Each tab 54 forms an inclined ramp (FIG. 4), and preferably terminates
with a tooth. At the opposite end of the tab 54 each column formation
lever 53 has a control pushbutton 55. Finally, each column formation lever
53 is provided with a shutter tab 56 which normally projects from the
composition table 38 at the lower end of the corresponding column and
retains the balls E contained therein, which thus remain aligned one on
the other between the protruding guides 39.
All the control pushbuttons 55 of the various column formation levers 53
are disposed as to form a keyboard 59, and they are each marked, for
example, by a number from 1 to 12, whilst the same numbers are impressed
at the head of the corresponding columns of the composition table 38, in
order to facilitate singling out the pushbutton corresponding to each
column. The levers 53 have alternatively two different lengths, so that
their pushbuttons 55 which form the keyboard 59 are displaced on two
levels (FIGS. 1 and 7), and they can be disposed at such a respective
spacing as to allow easy fingering.
In register with the pushbuttons 55 there is a stroke limiting member 60
(FIGS. 7 and 8), slidable along a transversal direction within the
box-like body 20, retained in the position shown in the drawings by means
of a return spring 63 and displaceable by means of a control projection 61
protruding from the cover 28. The limiting member 60 is provided with
prongs 62 adapted to hold up the pushbottons and, normally, to limit the
stroke of these latter to what is sufficient to control the deviation tabs
54. By displacing the limiting member 60, the prongs 62 cease holding up
the pushbuttons 55 and limiting their stroke; it is then possible to
continue lowering a pushbutton 55 till the shutter tab 56 is made to
disappear below the composition table 38. By this operation, the end of a
column of the composition table 38 is released, and this column is emptied
of the balls E which were contained therein and which descend into the
return passageway 36 and collect within the lower reservoir 24.
The apparatus according to this invention is used as follows. A certain
quantity of differently coloured balls A is initially contained within the
lower reservoir 24. By inclining the apparatus opposite its slope in the
condition of use, at least a part of the balls is transferred, through the
charging passage 37, to the upper store 32, where these balls B collect in
an orderly way by resting on each other, whilst the lowest of them, the
ball C, enters the mouth 34 of the launching passageway 35 and remains
stationary therein, retained between the tab 42, the launching member 46
and the retaining member 47. The composition starts from this situation.
If the ball C is of an undesired colour, it can be rejected by striking the
pushbutton 52 without actuating any column formation pushbutton; in this
case, the ball passes through the whole launching passageway 35 and then
through the return passageway 36, and returns to the lower reservoir 24.
If more balls have to be rejected, the above operation may be repeated
more times or, alternatively, the pushbutton 43 may be pressed to render
temporarily accessible the rejection passage 33.
If, on the contrary, in the position C there is a ball which is intended to
be located in a certain column of the composition table 38, the pushbutton
55 which corresponds to the chosen column is pressed and, by keeping said
pushbutton in the pressed condition, also the pushbutton 52 is struck;
then the ball is launched into the launching passageway 35, but it meets
with the raised deviation tab 54; the ball D climbs the ramp of this tab
and, by rising on the side opposite the wall 40 of the composition table
38, may thus override said wall and fall into the selected column of the
composition table, then stopping against the shutter tab 56 or against the
other balls already contained in the same column. The end tooth of the
deviation tab 54 ensures a suitable deviation of the ball in those cases
in which some uncertainties of in the deviation could arise.
In order to allow the balls to override the wall 40 and then compel them to
insert themselves between the guides 39 of the selected column, the cover
28 has, in register with the launching passageway 35, a raised portion
delimited by an inclined wall 28'. Preferably, this latter has also, in
successive sections each corresponding to one of the columns of the
composition table 38, a transversal slope which serves to make the
deviated ball rebound towards the corresponding column. Furthermore, the
cover has wall sections 28" directed towards the corresponding protruding
guides 39, in order to completely separate the various columns also in
register with the raised portion of the cover. In its portion which covers
the composition table 38, the cover 28 extends parallel to the composition
table at a distance therefrom which is slightly larger than the diameter
of the balls used. Thanks to the whole of these provisions, both the
slowly launched and the more rapid balls are directed, without any
uncertainty, towards the selected columns.
By repeating the process described hereinabove and by suitably selecting
each time the activated column formation pushbutton, it is possible to
direct to the various columns of the composition table, in the desired
order, the balls having the selected colours, thus composing on the table
38 a mosaic of balls which form the desired pattern.
In case of error, the column in which the error has occurred may be emptied
by actuating the corresponding pushbutton 55 after having displaced, by
means of the control projection 61, the limiting member 60, and then
making disappear below the rolling plane 31 the shutter tab 56
corresponding to the column to be emptied.
In order to facilitate the composition, especially as long as the person
using the apparatus is not yet familiar with this latter, a card 64
showing a previously prepared pattern may be inserted into a corresponding
slot provided between the composition table 38 and the bottom of the body
20. The card 64 can be seen through the composition table 38, which, as
already said, is transparent, and guides the composition of the balls in
conformity with the pattern, thus rendering said composition much easier
to be carried out. To allow then an easier withdrawal of the card 64, a
cavity 65 is formed in the corresponding portion of the body 20.
Should the balls 8 contained in the upper store 32 not be sufficient to
complete the composition, other balls may be moved from the position A to
the position B, by inclining the apparatus again opposite its slope in the
condition of use. This does not involve the destroying the composition
already carried out, because during this operation the balls contained in
the columns of the composition table 38 are stopped by the transversal
wall 40 and cannot leave the respective columns. To allow providing, in
register with the wall 40, a sufficiently high step which surely could not
be overridden by the balls, the composition table 38 is arranged with a
slope slightly lesser than that of the rolling plane 31, as it can be seen
in FIG. 7.
At the end of the composition, the upper store 32 may be rapidly emptied by
actuating the pushbutton 43 and thus clearing the passage to the rejection
passageway 33.
Of course, various constructive modifications may be made to the embodiment
described hereinabove by way of example. For instance, the legs 29 may be
constructively separated from the body 20 and be applied thereon for the
use of the apparatus and detached therefrom for being put away. Devices
different from those described herein could be used for launching the
balls, for deviating them towards the columns in which they have to be
disposed and for rejecting the undesired balls. The emptying of the
columns could be controlled by means of pushbuttons separated from the
column formation pushbuttons.
