Description

Vorrichtung zur Verhinderung von Manipulationen an Tischspielgeraten Device for preventing tampering with table game devices
Beschrei ungDescription
Die Erfindung betrifft ei e Vorrichtung zur Verhinderung von Manipulationen an Tischspielgeraten, insbesondere Tischfu߬ ballgeräten, mit einem Spielfeld sowie wenigstens einem Tor¬ raum und einen mit diesem verbundenen Ballschacht.The invention relates to a device for preventing tampering with table game devices, in particular table football devices, with a playing field and at least one goal area and a ball shaft connected thereto.
Bei Tischspielge aten, insbesondere münzbetätigten Geräten, werden für ein Spiel oder eine Spielsequenz entweder eine besti mte Anzahl an Bällen bereitgestellt oder es kann wäh¬ rend einer bestimmten Zeitdauer gespielt werden und nach deren Ablauf solange mit dem dann auf dem Spielfeld befind¬ lichen Ball weitergespielt werden, bis dieser im Tor ver- schwi ndet .In table games, in particular coin-operated devices, either a certain number of balls are provided for a game or a game sequence, or it can be played during a certain period of time and after this has elapsed, the ball then remaining on the field continues to be played until it disappears into the gate.
Um ohne Geldeinsatz spielen zu können, haben die Spieler verschiedene Manipulationsmaßnehmen erdacht. So kommt es immer wieder vor, daß in den Torraum Fremdkörper, Mützen, Schals, Schwämme etc. gestopft werden. Der Ball kann auf diese Weise durch ein Tor, d.h. einen Treffer, nicht verlo¬ rengehen und es kann beliebig lang mit einem Ball gespielt werden. Statt des Einsetzens eines Fremdkörpers sind auch einige Spieler dazu übergegangen, den Torraum bzw. das Öffnen des Tors durch maßgenaue Metal 1 /Hol zschei ben abzu¬ decken . Eine Alternative zu diesen Manipulationsmaßnahmen könnte darin bestehen, eigene Bälle mitzubringen. Dies hätte in¬ dessen den Nachteil , daß diese im Fall eines Tors verloren¬ gingen. Es würde sich dann nur die Frage stellen, was teurer wäre, der Ball oder ein Zukauf von S ielzeit.In order to be able to play without spending money, the players have devised various manipulation measures. So it happens again and again that foreign objects, caps, scarves, sponges etc. are stuffed into the goal area. In this way, the ball cannot be lost through a goal, ie a goal, and a ball can be played for as long as desired. Instead of inserting a foreign body, some players have also started to cover the goal area or the opening of the goal with dimensionally accurate metal 1 / wooden discs. An alternative to these manipulation measures could be to bring your own balls. This would, however, have the disadvantage that they would be lost in the event of a goal. The only question then would be, what would be more expensive, the ball or a purchase of game time?
Durch derartige Manipulationen entstehen den Aufstellern solcher Tischspielgeräte teilweise erhebliche Umsatzausfäl¬ le, so daß Gegenmaßnahmen überlegt worden sind. So ist in der DE-A-26 57 834 eine Vorrichtung für ein Tischfußball- gerät vorgeschlagen worden, die mit einer Zustopfsperre in Form eines Fingers versehen ist, der mit der den Torwart tragenden Spielstange verbunden ist und hin und her ver¬ schiebbar ist. Der Finger ist über eine Teleskopanordnung mit einem an der Spielstange befestigten Mitnehmer ver¬ bunden .Manipulations of table game devices of this type sometimes result in considerable sales losses, so that countermeasures have been considered. In DE-A-26 57 834 a device for a table football device has been proposed which is provided with a plug in the form of a finger, which is connected to the game bar carrying the goalkeeper and can be moved back and forth. The finger is connected via a telescopic arrangement to a driver attached to the play bar.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Verhinderung von Manipulationen an Tischspielger ten, insbesondere Ti schfußbal 1 ger ten , zu schaffen, mit der Mani¬ pulationen im Torbereich wirksam verhindert werden können.The invention has for its object to provide a device for preventing tampering with Tischspielger th, in particular Ti schfußbal 1 ger th, with which tampering in the gate area can be effectively prevented.
Die Aufgabe ist durch die Erfindung bei einer Vorrichtung mit den Merkmalen 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche .The object is achieved by the invention in a device with the features 1. Advantageous further developments are the subject of the subclaims.
Eine erfindungsgemäße Vorrichtung zur Verhinderung von Ma¬ nipulationen an Tischspielgeraten, insbesondere Tischfu߬ ballgeräten, weist ein Spielfeld sowie wenigstens einen Torraum und einen mit diesem verbundenen Ballschacht und ferner eine den Torraum erfassende Sender/Empfängerein¬ richtung auf. Bei einer Manipulation wird in der Empfänger¬ einrichtung das Sendesignal nicht empfangen. Eine nachge¬ schaltete Auswahleinrichtung kann dann einen Manipulations- al arm ausgeben .A device according to the invention for preventing manipulation of table game devices, in particular table football devices, has a playing field and at least one goal area and a ball shaft connected to it, and furthermore a transmitter / receiver device which detects the goal area. In the event of manipulation, the transmission signal is not received in the receiver device. A downstream selection device can then be manipulated. to spend al poor.
Mit der erfindungsgemäßen Vorrichtung ist es nicht mehr erforderlich, mechanische Sperren vorzusehen. Vielmehr braucht lediglich die Sender/Empf ngereinrichtung an ge¬ eigneter Stelle eingebaut zu werden. Wichtig dabei ist, daß diese den Torraum möglichst vollständig überstreicht. Wird der Torraum durch Fremdkörper (z.B. einen Schwamm, einen Schal oder dergleichen) verstopft, so wird die Amplitude des Empfängersignals deutlich und dauernd verringert, d.h. es wird gar kein Signal empfangen. Der Spielball beeinflußt hierbei das Empfängersignal nur kurzzeitig und geringfügig. Dies kann wiederum dazu ausgenutzt werden, ein entsprechen¬ des Manipulationssignal auszugeben.With the device according to the invention, it is no longer necessary to provide mechanical locks. Rather, only the transmitter / receiver device needs to be installed at a suitable location. It is important that this covers the goal area as completely as possible. If the goal area is blocked by foreign objects (e.g. a sponge, a scarf or the like), the amplitude of the receiver signal is significantly and permanently reduced, i.e. no signal is received at all. The game ball influences the receiver signal only briefly and slightly. This can in turn be used to output a corresponding manipulation signal.
Mittels eines derartigen Manipulationssignals kann bei¬ spielsweise eine mechanische Sperre ausgelöst werden, die ein weiteres Spielen verhindert. Ferner kann es vorgesehen werden, eine optische oder akustische Anzeige auszulösen, die entweder für jedermann wahrnehmbar ist, oder die Auf¬ sichtsperson benachrichtigt.A manipulation signal of this type can be used, for example, to trigger a mechanical lock which prevents further play. Furthermore, provision can be made to trigger a visual or acoustic display which is either perceptible to everyone or which notifies the supervisor.
Die Sender/Empf ngereinrichtung kann so ausgewählt sein, daß eine solche Einrichtung jeweils mit einem Sender/Empf nger, kombiniert mit oder ohne Reflektor, in einem Torraum ange¬ ordnet wird. Weist das betreffende Ti schspi el gerät zwei ge¬ genüberliegende Tore auf, so kann vorteilhaft vorgesehen werden, im Bereich des einen Torraums die Sendereinrichtung im Bereich des anderen Torraums die Empfängereinrichtung vorzusehen. Hierdurch können Bauteile eingespart werden.The transmitter / receiver device can be selected such that such a device is arranged in each case with a transmitter / receiver, combined with or without a reflector, in a goal area. If the relevant table game device has two opposite gates, it can advantageously be provided to provide the transmitter device in the area of the one goal area and the receiver device in the area of the other goal area. This can save components.
Es kann vorgesehen werden, als Sender/Empfängereinrichtung eine optische Anordnung, insbesondere Lichtschranke, deren Sender ein getaktetes Signal ausgibt, vorzusehen. Durch O 95/35138It can be provided to provide an optical arrangement, in particular a light barrier, the transmitter of which emits a clocked signal as the transmitter / receiver device. By O 95/35138
geeignete Beschaltung bzw. Anordnung der Teile kann auch verhindert werden, daß das Störsignal durch das Spielge¬ schehen die Erfassung verhindert. Weniger störanfällig und insbesondere unabhängig von Spielfiguren ist eine insbeson¬ dere mit Ultraschall arbeitende akustische Anordnung der Sender/Empfängereinrichtung.suitable wiring or arrangement of the parts can also be prevented that the interference signal prevents the detection by the game events. An acoustic arrangement of the transmitter / receiver device that works in particular with ultrasound is less susceptible to interference and, in particular, is independent of game characters.
Bei einem bevorzugten Ausführungsbeispiel der erfindungsge¬ m ßen Vorrichtung gibt der Ultraschallsender ein getaktetes Signal aus. Dies verhindert, daß sich im Fall mehrerer im selben Raum aufgestellter Geräte diese nicht gegenseitig stören. Der Takt des Sendesignals ist vorzugsweise einstell¬ bar und kann beispielsweise dem ASCII-Code für Buchstaben entsprechen. Hierbei bedeutet eine logische Eins, daß der Sender angesteuert wird und eine defnierte Zeit (z.B. 1 ms) schwingt. Eine logische Null bedeutet eine Sendepause glei¬ cher Zeitdauer. Erkennt der Empfänger in der Sendepause ein Signal , so muß der GesamtVorgang nach einer Pause neu ge¬ startet werden. Hierbei sind die Pausen deutlich länger als die Sendezeiten.In a preferred embodiment of the device according to the invention, the ultrasound transmitter outputs a clocked signal. This prevents that in the case of several devices installed in the same room they do not interfere with each other. The clock of the transmission signal is preferably adjustable and can, for example, correspond to the ASCII code for letters. A logical one means that the transmitter is activated and a defined time (e.g. 1 ms) oscillates. A logical zero means a transmission pause of the same duration. If the receiver recognizes a signal during the pause, the entire process must be restarted after a pause. The breaks are significantly longer than the broadcast times.
Weist das Tischspielgerät eine im Einlaυfbereich des Ball¬ schachts angeordnete Ballplatte auf, so kann diese vorteil¬ haft dazu ausgenutzt werden, den Strahl eines Ultraschall¬ senders von einem Tor zum anderen zu leiten. Hierbei ist der Sender im Reflexionsbereich einer solchen Prallplatte eines erssten Tors angeordnet und der Empfänger im Bereich einer solchen Prallplatte eines zweiten Tors angeordnet. Auf diese Weise befinden sich die Sender/Empf ngerteile außerhalb des Spielfeldes und sind gegen direkten Beschüß durch die Bälle geschützt, ohne daß die Detektionsgenauigkeit verringert i st .If the table game device has a ball plate arranged in the inlet area of the ball shaft, then this can advantageously be used to guide the beam of an ultrasound transmitter from one gate to the other. Here, the transmitter is arranged in the reflection region of such a baffle plate of a first gate and the receiver is arranged in the region of such a baffle plate of a second gate. In this way, the transmitter / receiver parts are outside the playing field and are protected against direct bombardment by the balls, without the detection accuracy being reduced.
Ist das betreffende Ti schspi el gerät mit einem Bai 1 ei tel ement am Ballschacht versehen, so kann die Sender/Empf ngerein¬ richtung an dem Bai 1 ei tel ement angeordnet sein.If the table in question is equipped with a beam element provided on the ball shaft, the transmitter / receiver device can be arranged on the beam element.
Die Erfindung wird im folgenden weiter anhand eines Ausfüh¬ rungsbeispiels und der Zeichnung erläutert, wobei diese le¬ diglich zu Erl uterungszwecken dienen und nicht im ein¬ sch nkenden Sinn zu verstehen sind.The invention is further explained below with the aid of an exemplary embodiment and the drawing, these serving only for explanatory purposes and are not to be understood in a restrictive sense.
In der Zeichnung zeigt die einzige Figur eine schematische Schnittdarstellung durch den Torbereich eines Tischspiel¬ geräts .In the drawing, the single figure shows a schematic sectional view through the goal area of a table game device.
Das in der Zeichnung schematisch dargestellte Tischspiel¬ gerät weist ein Spielfeld 2 auf, das von einem äußeren Rah¬ men 3 umgeben bzw. begrenzt ist. Der Rahmen 4 weist eine Bodenplatte 6, senkrechte Seitenplaten 8 und obere Rand¬ platten 10 auf. Von den Platten 10 ist eine wiederum senk¬ rechte Begrenzungsplatte 12 nach unten abgewinkelt, die im Torbereich ausgeschnitten ist und im übrigen mit dem Spiel¬ feld 2 - ebenfalls einer Platte - verbunden ist. Der Rahmen 4 kann einstückig ausgebildet sein.The table game device shown schematically in the drawing has a playing field 2 which is surrounded or delimited by an outer frame 3. The frame 4 has a base plate 6, vertical side plates 8 and upper edge plates 10. From the plates 10, a again vertical boundary plate 12 is angled downwards, which is cut out in the goal area and is otherwise connected to the playing field 2 - also a plate. The frame 4 can be formed in one piece.
Wie erwähnt, weisen die Begrenzungsplatten 12 im Torbereich Ausschnitt 14 auf, die die betreffenden Toröffnungen bilden. Im dargestellten Ausführungsbeispiel erstreckt sich hinter der Toröffnung, d.h. auf der Rückseite der Begrenzungsplatte 12, von deren unterem Rand eine Prallplatte 16 schräg nach hinten bis zur senkrechten Seitenplatte 8. Die Prallplatte 16 bildet die obere BVegrenzung des durch die Seitenplatte 8 und das Spielfeld 2 gebildeten Ballschachts 18 für Bälle, die die Toröffnung passiert haben. Am unteren Ballschatende befindet sich ein Bai 1 ei tel ement 20 in Form einer schrägge¬ stellten Platte, die sich von der Seitenplatte 8 schräg nach unten in Richtung des Spielfeldes erstreckt. Das Balleitele- ment bildet die untere Begrenzung des Ballschachts 18. Ein Ball , der durch den Ballschacht nach unten gefallen ist, rollt dann das Bai 1 ei tel ement nach unten in den Raum zwi¬ schen der Bodenplatte 6 und dem Spielfeld 2, wo die gespiel¬ ten Bälle gesammelt werden. Die bereits erwähnte Prallplatte 16 bewirkt durch ihre Schrägstellung, daß durch die Toröff¬ nung 14 geschossene Bälle nicht wieder zurück auf das Spiel¬ feld 2 gelangen können, sofern sie nach unten in Richtung des Bai 1 ei tel ements reflektiert werden.As mentioned, the boundary plates 12 have cutout 14 in the gate area, which form the relevant gate openings. In the illustrated embodiment extends behind the gate opening, ie on the back of the boundary plate 12, from the lower edge of which a baffle plate 16 slants backwards to the vertical side plate 8 Ball shaft 18 for balls that have passed the gate opening. At the lower end of the ball shadow there is a ball element 20 in the form of a slanted plate which extends obliquely downward from the side plate 8 in the direction of the playing field. The Balleitele element forms the lower boundary of the ball shaft 18. A ball that has fallen down through the ball shaft then rolls the ball 1 element downward into the space between the base plate 6 and the playing field 2, where the played Balls are collected. Due to its inclined position, the aforementioned baffle plate 16 means that balls shot through the gate opening 14 cannot get back onto the playing field 2, provided that they are reflected downwards in the direction of the ball element.
Diese Anordnung ist bei dem Einbau der erfindungsgemäßen Sender/Empfängereinrichtung genutzt worden. In dem in der Figur linken Bai 1 ei tel ement 20 ist ein Ultraschal 1 sender 22 eingebaut worden, so daß dieser seinen Sendestrahl möglichst kleiner Streuung und Richtcharakteristik auf die darüber be¬ findliche Prallplatte 16 im hinteren Torraum richtet. Die Schallwellen werden an der Prallplatte reflektiert und mehr oder weniger parallel zum Spielfeld 2 über dieses hinweg zur gegenüberliegenden Prallplatte 16 gestrahlt. Dies ist durch das Bezugszeichen 24 veranschaulicht. An der betreffenden Prallplatte 16 werden die Ultraschal lwel 1 en nach unten reflektiert und gelangen zu einem Ul traschal 1 empfänger 26, der wie der Ultraschallsender 22 in dem betreffenden Ball¬ leitelement 20 eingebaut ist. Die sich etwa kegelförmig ausbreitenden Ul traschal 1 wel 1 en laufen praktisch durch die Spielfiguren und Spielstangen ungehindert über das Spielfeld 2. Solange das ausgesendete Ul traschal 1 si gnal vom Ultra¬ schal 1 empfänger 26 empfangen wird, findet keine Manipulation statt . This arrangement was used when installing the transmitter / receiver device according to the invention. An ultrasound 1 transmitter 22 has been installed in the left-hand beam element 20 in the figure, so that it directs its transmission beam with the smallest possible scatter and directional characteristic onto the baffle plate 16 located above it in the rear goal area. The sound waves are reflected on the baffle plate and are radiated more or less parallel to the playing field 2 over the latter to the opposite baffle plate 16. This is illustrated by reference number 24. The ultrasonic waves 1 are reflected downward on the relevant baffle plate 16 and arrive at an ultrasonic receiver 26 which, like the ultrasonic transmitter 22, is installed in the relevant ball guide element 20. The ul traschal 1 wel 1 s, which spread out in a conical shape, practically run freely through the playing figures and playing bars over the playing field 2. As long as the transmitted ul traschal 1 signal is received by the ultrasound 1 receiver 26, no manipulation takes place.
