[0001] The invention refers to a portable electronic table to visualize the turnover of
the players in the sport games characterized by matches between two teams. In essential
the invented device consists of a double-faced table having on both the faces a display
formed by four light panels on which contemporary is visualized with light indication
both the number of the player who must go out than the number of the player who must
go on. It is so realized an instantaneous communication of the turnover information
both for who is on the playing field than for the public came to see the exibition
and situated on the tiers. The current electronic devices for visualizing the turnover
of the players on the field given this information with two succesive sequences: in
the first one is exibited the number of the player who must go out and in the second
one is exibited the number of ther player who must go on. Considering that the quickness
with which said turnovers are made is very important to limit the game fragmentariness
and to reduce to a minimum the interruption time in the game which comes to damage
the match spectularity, the invented device permits to have more time of effective
game since it reduces the comunication time for the various turnovers. The invented
portable table to be fed with direct current by a battery 1 to be recharged by a power
supply. Said current, acting on a push button 2, comes in a first sequence to a microprogrammed
control card 3 contemporary starting two service displays 4 and 5 simmetrically placed
on the lateral borders of the back face of the portable table.
[0002] Said service displays acting as numeric selectors of pre-setting of the two figure
numbers,one regarding the player who must go out and the other regarding the player
calls to replace him. Said pre-setting numbers are formed by the operator acting in
sequence by four push buttons: two push buttons provide for the first display 4 and
two push buttons provide for the second display 5. For the first display 4 a couple
of push buttons 6 and 7 are used whereas for the second display 5 a couple of push
buttons 8 and 9 are used.
[0003] Said push buttons to be pressed, in both the couples, one for incrementing the number
from 00 to 99 and the other for decreasing the same from 99 to 00. The pre-set numbers
are permanently visualized on the service displays 4 and 5. Pressing the push button
10 or alternatively the push button 11, which perform an only one operation, the same
numbers are contemporary send in the case of the numbers formed on the service display
4 to light panels 12 and 13 placed in couple onto the front left part of the table
and to the light panels 14 and 15 placed in couple onto the back right part of the
table. Whereas the numbers formed on the service display 5 are sent to the light panels
16 and 17 placed in couple onto the front right part of the table and to the light
panels 18 and 19 placed in couple onto the back left part of the table.The invented
table 20 has a push button 21 to cancel the pre-set numbers formed on the service
displays 4 and 5. The zero condition is showed forming the number one on the two displays.
To control the storage of the battery 1 a push button 22 is provided placed in the
middle of the table 20 visualizing on the service display 5 a two figure number stated
percentually the storage level of the same battery. Said numeric information remains
visualized with said push button 22 pressed. Externally the portable table 20 provides
two nonskid handling parts 23 and 24 so permitting to the operator to put the table
in use position for visualizing the infomation. On the same table two parts 25 and
26 are provided for advertising messages. The portable table and its working are illustrated
in the drawings of sheets 1 and 2. In sheet 1 fig. 1 is a schematic block diagram
illustrating the device working. In sheet 2 fig. 2 is view of the front face of the
portable table 20. Fig. 3 is view of the back face of the same portable table 20 exibited
by the operator to give the information regarding the turnover.
1. Portable light table for the turnover of the players onto the playing field to be
fed with direct current by a battery (1) to be recharged by a power supply, where
said current, acting on a push button (2), comes in a first sequence to a microprogrammed
control card (3) contemporary starting two service dispalys (4 and 5) simmetrically
placed on the lateral borders of the back face of the portable table and where the
double-faced table has on both the faces a display formed by four light panels, characterized
in that:
- the service dispalys act as numeric selectors of pre-setting of the two figure numbers,
one regarding the player who must go out and the other regarding the players calls
to replace him, said pre-setting numbers formed by the operator acting in sequence
by four push bottons: two push buttons (6 and 7) provide fo the first dispaly (4)
and two push buttons (8 and 9) provide for the second display (5);
- said push buttons to be pressed, in both the couples, one for incrementing the number
from 00 to 99 and the other for decreasing the same from 99 to 00 where the pre-set
numbers are permanently visualized on the service displays (4 and 5);
- pressing a push button (10) or alterntively an other push button (11), which perform
an only one operation, the numbers are contemporary send in the case of the numbers
formed on the first service display (4) to light panels (12 and 13) placed in couple
onto the front left part of the table and to the light panels (14 and 15) placed in
couple onto the back right part of the table, whereas the numbers formed on the second
service display (5) are sent to light panels (16 and 17) placed in couple onto the
front right part of the table and to light panels (18 and 19) placed in couple onto
the back left part of the table;
- the table (20) has a push button (21) to cancel the pre-set numbers formed on the
service displays (4 and 5) and the zero condition is showed forming the number one
one the two displays.
2. Portable light table for the turnover of the players onto the playing field, as per
claim 1), characterized in that to control the storage of the battery (1) a push button
(22) is provided placed in the middle of the table (20) visualizing on the service
display (5) a two figure number stated percentually the storage level of the same
battery; said numeric information remains visualized with said push button (22) pressed.
3. Portable light table for the turnover of the players onto the playing field, as per
claim 1), caracterized in that externally the table (20) provides two nonskid handling
part (23 and 24) so permitting to the operator to put the table in use position for
visualizing the information.
