The front door (3) is articulated to the housing (2) on one of its vertical longitudinal sides (5) by a hinge (4). The suporting disk (15) with the switch matrix (13) is fastened to the rear face of the front door (3) so that it can be folded back.

Description

Die Erfindung bezieht sich auf ein Wurfpfeil-Spielgerät mit einer Wurfpfeil-Scheibe, die in eine an einer ihrer vertikalen Längsseiten über ein Scharnier an einem Gehäuse angelenkte Fronttür eingesetzt ist und deren bewegliche, mit unterschiedlichen Punktezahlen belegte, zwischen radialen und konzentrischen Rippen liegende Segmente Löcher zur Aufnahme der Wurfpfeile aufweisen, wobei die in ihrer Bewegung nach vorne durch Halteeinrichtungen gesicherten Segmente beim Auftreffen eines Wurfpfeiles eine an einer Trägerplatte angeordnete Schaltermatrix betätigen, die über eine Schalteinrichtung eine automatische Registrierung, Aufzählung und Anzeige der erzielten Punkte ermöglicht.The invention relates to a dart game device with a dart disk, which is inserted into a front door articulated on one of its vertical long sides via a hinge to a housing, and whose movable segments, which are occupied with different scores, lie between radial and concentric ribs have for receiving the darts, the segments secured in their forward movement by holding devices actuate a switch matrix arranged on a carrier plate when a dart strikes, which enables automatic registration, enumeration and display of the points achieved via a switching device.

Derartige Wurfpfeil-Spielgeräte sind in den verschiedensten Ausführungsformen bekannt. So zeigt beispielsweise die DE 37 23 298 Al ein Wurfpfeil-Spielgerät mit einer in einer Öffnung der Frontwand eines Gehäuses angebrachten Wurfpfeil--Scheibe, deren bewegliche, mit unterschiedlichen Punktezahlen belegte Segmente Löcher zur Aufnahme der Wurfpfeile aufweisen. Die Segmente betätigen beim Auftreffen eines Wurfpfeiles über eine elastische Unterlage eine zwischen dieser Unterlage und einer Trägerplatte angeordnete Schaltergruppe, die über elektrische und/oder elektronische Bauelemente eine automatische Registrierung, Aufzählung und Anzeige der erzielten Punkte ermöglicht. Hierbei sind die elastische Unterlage, die Schaltergruppe und die Trägerplatte als Einheit mit der Wurfpfeil-Scheibe von der Frontwand und anschließend von der Wurfpfeil-Scheibe abklappbar. Die Wurfpfeil-Scheibe ist über ein Gelenk und einer dem Gelenk gegenüberliegenden Verschlußeinrichtung an der Frontwand des Gehäuses gehalten. Mit der Wurfpfeil-Scheibe ist die Trägerplatte über ein Gelenk verbunden und liegt im eingeklappten Zustand in der Frontwand an einem entsprechenden gehäuseseitigen Anschlag der Frontwand an. Zwar ist es bei diesem Wurfpfeil-Spielgerät möglich, lediglich durch zwei Klappvorgänge den freien Zugang zu der Rückseite der Segmente der Wurfpfeil-Scheibe zu erhalten, um abgebrochene Pfeilspitzen zu beseitigen oder ggfls. defekte Segmente austauschen zu können, jedoch ist hierbei eine gewisse Instabilität der in die Frontwand eingesetzten Wurfpfeil-Scheibe gegeben, da diese in ihrer Betriebsstellung lediglich durch das Gelenk und die Verschlußeinrichtung gehalten ist, was dazu führt, daß die Wurfpfeil-Scheibe seitlich mittels eines Werkzeuges hintergriffen werden kann, um nichtzulässige Manipulationen an dem Wurfpfeil-Spielgerät vorzunehmen. Darüber hinaus können bei abgeklappter Wurfpfeil-Scheibe und hochgeklappter Einheit aus Unterlage, Schaltergruppe und Trägerplatte infolge unvorsichtiger Hantierung an der Wurfpfeil-Scheibe die Segmente aus der Wurfpfeil-Scheibe herausgleiten und gegebenenfalls zu Boden fallen, wodurch ein Arbeitsmehraufwand entsteht.Such dart game devices are known in a wide variety of embodiments. For example, DE 37 23 298 A1 shows a dart game device with a dart disk mounted in an opening in the front wall of a housing, the movable segments of which have different points and have holes for receiving the dart. When a dart strikes an elastic base, the segments actuate a switch group arranged between this base and a carrier plate, which enables automatic registration, enumeration and display of the points achieved via electrical and / or electronic components. Here are the elastic pad, the switch group and the support plate as a unit with the dartboard from the front wall and then foldable from the dartboard. The dart target is held on the front wall of the housing by means of a joint and a closure device opposite the joint. The carrier plate is connected to the dartboard disc by a hinge and, when folded, lies in the front wall against a corresponding stop on the housing side of the front wall. It is possible with this dart game device to get free access to the back of the segments of the dart target by simply folding two times in order to remove broken arrow heads or if necessary. to be able to replace defective segments, however, there is a certain instability of the dartboard disc inserted into the front wall, since this is held in its operating position only by the joint and the locking device, which leads to the dartboard disc being laterally by means of a tool can be used to make unauthorized manipulations on the dart game device. In addition, when the dart target disc is folded down and the unit consisting of the pad, switch group and carrier plate is folded up, the segments can slide out of the dart target disc and, if necessary, fall to the ground as a result of careless handling of the dart target disc, resulting in additional work.

Des weiteren ist aus der EP 0 332 003 Al ein Wurfpfeil-Spielgerät mit elektronischer Trefferanzeige bekannt, das eine von mindestens einem Teil der Vorderseite des Gehäuses gebildete Servicetür für den Zugriff in das Geräteinnere von der Vorderseite des Gehäuses her aufweist. Die eine Wurfpfeil-Scheibe tragende Servicetür ist durch ein an ihrem unteren Ende angebrachtes Scharnier mit dem Gehäuse verbunden. Aufgrund dieses Scharniers kann die Servicetür zwischen einer im allgemeinen vertikalen Betriebsposition und einer Serviceposition, bei der sich die Servicetür von der Vorderseite des Gehäuses in einem vorbestimmten Winkel von weniger als 180° nach außen erstreckt, verschwenkt werden. Um zu vermeiden, daß die Servicetür in eine Position schwenkt, die den vorbestimmten Winkel überschreitet, ist zwischen der Servicetür und dem Gehäuse mindestens ein flexibles Glied entsprechender Länge vorgesehen. In der Serviceposition der Servicetür verhindern Halteeinrichtungen ein Herausfallen der Segmente aus den radialen und konzentrischen Rippen der Wurfpfeil-Scheibe. In dieser Position kann eine auf der Rückseite der Servicetür mittels Schrauben befestigte Tragplatte für eine den Segmenten der Wurfpfeil-Scheibe zugeordnete Schaltermatrix nach Lösen der Schrauben entfernt werden, um abgebrochene Pfeilspitzen aus der Wurfpfeil-Scheibe zu entfernen oder um beschädigte Segmente zu ersetzen. Nach dem Entfernen der abgebrochenen Pfeilspitzen aus der Wurfpfeil-Scheibe bzw. nach dem Ersetzen beschädigter Segmente muß die Tragplatte mit der Schaltermatrix wieder auf die Halteschrauben aufgesetzt und mittels auf die Halteschrauben aufgedrehter Muttern in ihrer Position festgelegt werden. Eine solche Vorgehensweise zum Entfernen abgebrochener Pfeilspitzen ist sonach zwangsläufig äußerst umständlich und zeitaufwendig, was demzufolge zu einer unverhältnismäßig langen Spielunterbrechung führt. Darüber hinaus ist bei diesem Wurfpfeil-Spielgerät neben dem Scharnier zwischen der Servicetür und dem Gehäuse mindestens ein flexibles Glied in Form einer Kette erforderlich.Furthermore, EP 0 332 003 A1 discloses a dart game device with electronic hit display which has a service door formed by at least part of the front of the housing for access to the interior of the device from the front of the housing. The service door, which carries a dartboard disc, is connected to the housing by a hinge attached to its lower end. Because of this hinge, the service door can be between a generally vertical operating position and a service position where the service door is from the front of the housing extends outwards at a predetermined angle of less than 180 °. In order to avoid that the service door pivots into a position that exceeds the predetermined angle, at least one flexible member of corresponding length is provided between the service door and the housing. In the service position of the service door, holding devices prevent the segments from falling out of the radial and concentric ribs of the dartboard. In this position, a support plate fastened on the back of the service door by means of screws for a switch matrix assigned to the segments of the dartboard disk can be removed after loosening the screws in order to remove broken arrowheads from the dartboard disk or to replace damaged segments. After removing the broken arrowheads from the dartboard or after replacing damaged segments, the support plate with the switch matrix must be replaced on the retaining screws and fixed in position by means of nuts screwed onto the retaining screws. Such a procedure for removing broken arrowheads is inevitably extremely cumbersome and time-consuming, which consequently leads to a disproportionately long game interruption. In addition, with this dart game device, in addition to the hinge between the service door and the housing, at least one flexible link in the form of a chain is required.

Ferner ist in der EP 0 332 003 Al ein Wurfpfeil-Spielgerät mit einer eine Wurfpfeil-Scheibe tragenden Front-Servicetür erwähnt, die an einer ihrer vertikalen Längsseiten über ein Scharnier am Gehäuse angelenkt ist und an der anderen Längsseite mit einem am Gehäuse angeordneten Schloß zusammenwirkt. Hierbei besteht jedoch die Gefahr, daß bei einer Wartung die von der Rückseite zugänglichen Segmente aus den Rippen der Wurfpfeil-Scheibe fallen, woraus eine zusätzliche Wartungszeit und Schwierigkeiten für das Wartungspersonal resultieren.Furthermore, EP 0 332 003 A1 mentions a dart game device with a front service door carrying a dart target, which is hinged to the housing on one of its vertical long sides and interacts with a lock arranged on the housing on the other long side . Here, however, there is a risk that the segments accessible from the rear during maintenance Ribs on the dart target fall, which results in additional maintenance time and difficulties for the maintenance personnel.

Der Erfindung liegt die Aufgabe zugrunde, ein Wurfpfeil-Spielgerät der eingangs genannten Art zu schaffen, bei dem das Entfernen von in der Wurfpfeil-Scheibe steckenden abgebrochenen Pfeilspitzen sowie ein Auswechseln beschädigter Segmente der Wurfpfeil-Scheibe auf einfache und schnelle Art bei feststehender Wurfpfeil-Scheibe gewährleistet ist.The invention has for its object to provide a dart game device of the type mentioned, in which the removal of broken arrowheads stuck in the dart target and replacement of damaged segments of the dart target in a simple and quick manner with a fixed dart target is guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Trägerplatte mit der Schaltermatrix abklappbar an der Rückseite der Fronttür befestigt ist, und die Segmente im abgeklappten Zustand der Trägerplatte gegen ein Herausfallen aus der Wurfpfeil-Scheibe nach vorn und hinten durch Führungseinrichtungen gesichert sind.This object is achieved in that the carrier plate with the switch matrix is hinged to the rear of the front door, and the segments are secured in the folded state of the carrier plate against falling out of the dartboard to the front and back by guide devices.

Die erfindungsgemäße Lösung gestattet es, lediglich durch Öffnen der Fronttür und anschließendem Abklappen der die Schaltermatrix aufnehmenden Trägerplatte von der Fronttür den freien Zugang zu der Rückseite der Segmente der Wurfpfeil-Scheibe zu erhalten, um die abgebrochenen Pfeilspitzen beseitigen oder ggfls. defekte Segmente austauschen zu können. Hierbei können die Segmente aufgrund der Führungseinrichtungen nicht unbeabsichtigt aus dem Rippen-Tragwerk der Wurfpfeil-Scheibe fallen, was die Wartungsarbeit wesentlich vereinfacht. Anschließend sind wiederum nur zwei Klappvorgänge, selbstverständlich in umgekehrter Reihenfolge, zur Erzielung der Spielbereitschaft des Wurfpfeil-Spielgerätes erforderlich. Eine solche Handhabung, bei der die Wurfpfeil-Scheibe stets in ihrer fest eingesetzten Position in der Fronttür verbleibt, läßt sich sehr rasch durchführen und bedingt demnach nur eine kurze Spielunterbrechung. Weiterhin ist kein besonderes Bauteil erforderlich, um die geöffnete Fronttür in ihrer Lage zu halten.The solution according to the invention makes it possible to obtain free access to the rear of the segments of the dartboard disc simply by opening the front door and then folding the carrier plate receiving the switch matrix from the front door, in order to remove the broken arrowheads or if necessary. to be able to exchange defective segments. Due to the guiding devices, the segments cannot accidentally fall out of the rib structure of the dartboard, which considerably simplifies the maintenance work. Subsequently, only two folding processes, of course in reverse order, are required to achieve the readiness of the dart game device to play. Such handling, in which the dart disc always remains in its fixed position in the front door, can be carried out very quickly and therefore requires only a short break in the game. Furthermore, no special component is required to hold the opened front door in place.

Bei einer vorteilhaften Ausgestaltung des Gegenstandes der Erfindung sind jedem Segment an seinen radialen Längsseiten jeweils zwei Führungseinrichtungen im bestimmten Abstand zueinander zugeordnet. So ergibt sich eine besonders zuverlässige Begrenzung der Rückwärts-Bewegung der Segmente bei abgeklappter Trägerplatte.In an advantageous embodiment of the subject matter of the invention, two segments are assigned to each segment on its radial longitudinal sides at a certain distance from one another. This results in a particularly reliable limitation of the backward movement of the segments when the carrier plate is folded down.

Um eine fertigungstechnisch einfache Realisierung der Führungseinrichtung zu erzielen, umfaßt nach einer weiteren vorteilhaften Ausgestaltung der Erfindung jede Führungseinrichtung einen an einer mit der jeweiligen Längsseite des Segmentes verbundenen Lappen endseitig angeformten Ansatz, der in Richtung der zugewandten radialen Rippe vorsteht und mit entsprechendem Spiel in einen hinterschnittenen Einschnitt dieser Rippe eingeklipst ist. Zur Erleichterung des Einklipsens des Ansatzes an dem Lappen des Segmentes in den zugehörigen Einschnitt der entsprechenden radialen Rippe ist bevorzugt der hinterschnittene Einschnitt in der radialen Rippe einer jeden Führungseinrichtung eingangsseitig mit gegenüberliegenden Anfasungen versehen. Zweckmäßigerweise sind die Führungseinrichtungen benachbarter Segmente versetzt zueinander angeordnet. So ergibt sich eine raumsparende Anordnung der Führungseinrichtungen.In order to achieve a production-technically simple implementation of the guide device, according to a further advantageous embodiment of the invention, each guide device comprises an attachment formed on the end on a tab connected to the respective long side of the segment, which protrudes in the direction of the facing radial rib and with corresponding play in an undercut Incision of this rib is clipped. In order to facilitate the clipping of the shoulder on the tab of the segment into the corresponding incision of the corresponding radial rib, the undercut incision in the radial rib of each guide device is preferably provided with opposite chamfers on the input side. The guide devices of adjacent segments are expediently arranged offset from one another. This results in a space-saving arrangement of the guide devices.

Das mit einem Sockel 1 versehene, sämtliche Funktionsteile des Wurfpfeil-Spielgerätes aufnehmende Gehäuse 2 weist eine rechteckförmige Fronttür 3 auf, die über ein als Klavierband ausgebildetes Scharnier 4 an dem Gehäuse 2 angelenkt ist. Das Scharnier 4 ist einerseits an der vertikalen Längsseite 5 der Fronttür 3 und andererseits an der entsprechenden Seitenwand 6 des Gehäuses befestigt ist, wobei die Fronttür 3 rechts- oder linksseitig an dem Gehäuse 2 angeschlagen sein kann. Dem Scharnier 4 gegenüberliegend befindet sich an der Fronttür 3 ein Schlüssel-Schloß 7, um die Fronttür 3 in ihrer geschlossenen Position mit dem Gehäuse 2 verschließen zu können. Das somit in Verbindung mit dem Sockel 1 als Standgehäuse ausgebildete Gehäuse 2 kann selbstverständlich auch ohne Sockel als Wandgehäuse ausgeführt werden.The housing 2, which is provided with a base 1 and accommodates all the functional parts of the dart game device, has a rectangular front door 3 which is hinged to the housing 2 via a hinge 4 designed as a piano hinge. The hinge 4 is fastened on the one hand to the vertical longitudinal side 5 of the front door 3 and on the other hand to the corresponding side wall 6 of the housing, the front door 3 being able to be attached to the housing 2 on the right or left side. Opposite the hinge 4 there is a key lock 7 on the front door 3 in order to be able to lock the front door 3 with the housing 2 in its closed position. The housing 2 thus designed in connection with the base 1 as a standing housing can of course also be designed as a wall housing without a base.

In die Fronttür 3 ist eine Wurfpfeil-Scheibe 8 fest eingesetzt, die eine Vielzahl von radialen Rippen 9 aufweist, welche mit gleichem Wlnkelabstand zueinander angeordnet sind. Die radialen Rippen 9 sind mit mehreren, mit unterschiedlichem Abstand zueinanderliegenden, konzentrischen Rippen 10 verbunden. In den Zwischenräumen zwischen den Rippen 9, 10 befinden sich gleitbewegliche Segmente 11, die mit einer Vielzahl von nicht dargestellten Öffnungen versehen sind, in die die Spitze eines Wurfpfeiles eindringen kann. Jedes Segment 11 besitzt Kontaktgeber 12, die mit zugehörigen Druckschaltern einer in Folie eingebetteten Schaltermatrix 13 zusammenwirken. Eine über ein Gelenk 14 abklappbar an der Rückwand der Fronttür 3 befestigte Trägerplatte 15 nimmt die Schaltermatrix 13 über in Richtung der Segmente 11 vorstehende Stifte 16 auf. Das Gelenk 14 der Trägerplatte 15 umfaßt eine benachbart zu dem Scharnier 4 parallel verlaufende Drehachse 17, die endseitig in an der Rückwand der Fronttür 3 angebrachten Halterungen 18 gelagert ist. Der fest mit der Trägerplatte 15 verbundenen Drehachse 17 gegenüberliegend befindet sich neben der Wurfpfeil-Scheibe 8 an der Rückwand der Fronttür 3 eine Verschlußeinrichtung 19, mittels der die die Schaltermatrix 13 aufnehmende Trägerplatte 15 in ihrer Betriebsposition gehalten wird. Wenn also bei geschlossener Fronttür 3 und geschlossener Trägerplatte 15 ein Segment 11 von einem Wurfpfeil getroffen wird, dann bewegt sich dieses Segment in Richtung der Trägerplatte 15, wodurch mindestens ein Kontaktgeber 12 des Segmentes 11 einen zugehörigen Druckschalter der Schaltermatrix 13 schließt. Der so erzeugte Trefferimpuls wird zu einem zentralen Mikroprozessor weitergegeben, der sämtliche Funktionen des Spielablaufes einschließlich der Registrierung, Aufzählung und Anzeige der aufgrund der mit unterschiedlichen Punktezahlen belegten Segmente erzielten Punkte steuert.In the front door 3 a dart disk 8 is firmly inserted, which has a plurality of radial ribs 9, which are arranged at the same angular distance from one another are. The radial ribs 9 are connected to a plurality of concentric ribs 10 located at different distances from one another. In the spaces between the ribs 9, 10 are slidable segments 11, which are provided with a plurality of openings, not shown, into which the tip of an arrow can penetrate. Each segment 11 has contactors 12 which interact with associated pressure switches of a switch matrix 13 embedded in foil. A support plate 15, which can be folded down on the rear wall of the front door 3 via a hinge 14, receives the switch matrix 13 via pins 16 protruding in the direction of the segments 11. The hinge 14 of the support plate 15 comprises an axis of rotation 17 running parallel to the hinge 4, which is mounted at the end in brackets 18 attached to the rear wall of the front door 3. The axis of rotation 17, which is fixedly connected to the support plate 15, is located next to the darting disk 8 on the rear wall of the front door 3, by means of a locking device 19 by means of which the support plate 15 receiving the switch matrix 13 is held in its operating position. If a segment 11 is hit by a dart with the front door 3 and the carrier plate 15 closed, then this segment moves in the direction of the carrier plate 15, whereby at least one contactor 12 of the segment 11 closes an associated pressure switch of the switch matrix 13. The hit pulse generated in this way is passed on to a central microprocessor, which controls all functions of the game sequence, including the registration, enumeration and display of the points achieved on the basis of the segments occupied with different number of points.

Jedes Segment 11 besitzt rückseitig an seinen radialen Längsseiten 20 zwei im bestimmten Abstand zueinander angeformte Lappen 21. Die jeweils gegenüberliegenden Lappen 21 der Längsseiten 20 des Segmentes 11 tragen eine Achse 22, auf der jeweils zwei als Kontaktrollen ausgebildete Kontaktgeber 12 gelagert sind. Die freien Enden jeder Achse 22 stehen über die Lappen 21 des Segmentes 11 vor und greifen derart in einen Einschnitt 23 der jeweils zugewandten radialen Rippe 9 der Wurfpfeil-Scheibe 8 ein, daß das Segment 11 nicht nach vorne aus der Wurfpfeil-Scheibe 8 herausgleiten kann. Um nun auch bei abgeklappter Trägerplatte 15 ein Herausgleiten der Segmente 11 nach hinten aus der Wurfpfeil-Scheibe 8 zu vermeiden, ist jedes Segment 11 in seiner freien Rückwärtsbewegung durch Führungseinrichtungen 24 begrenzt: Jede Führungseinrichtung 24 umfaßt einen endseitig an dem Lappen 21 seitlich nach außen vorstehenden Ansatz 25, der mit entsprechendem Spiel in den mit gegenüberliegenden Hinterschneidungen 26 versehenen Einschnitt 23 der zugewandten, radialen Rippe 9 eingeklipst ist. Hierbei ist also die Breite des Ansatzes 25 geringfügig größer als die Weite des Eingangs 27 des Einschnitts 23. Zur Erleichterung des Einklipsvorganges dienen die gegenüberliegenden Anfasungen 28 des Eingangs 27 des Einschnitts 23. Die Führungseinrichtungen 24 und damit Selbstverständlich auch die die Achsen 22 tragenden Lappen 21 benachbarter Segmente 11 sind seitlich versetzt zueinander angeordnet, um eine kompakte Bauweise zu ermöglichen.Each segment 11 has on the back on its radial longitudinal sides 20 two molded at a certain distance from each other Tabs 21. The opposite tabs 21 of the longitudinal sides 20 of the segment 11 carry an axis 22, on each of which two contactors 12 designed as contact rollers are mounted. The free ends of each axis 22 protrude beyond the tabs 21 of the segment 11 and engage in an incision 23 in the respective facing radial rib 9 of the dartboard 8 so that the segment 11 cannot slide forward out of the dartboard 8 . In order to prevent the segments 11 from sliding backwards out of the dartboard 8 even when the carrier plate 15 is folded down, each segment 11 is limited in its free backward movement by guide devices 24: each guide device 24 comprises an end projecting laterally outwards on the tab 21 Approach 25, which is clipped with corresponding play into the cut 23 of the facing radial rib 9 provided with opposite undercuts 26. Here, the width of the shoulder 25 is slightly larger than the width of the entrance 27 of the incision 23. The opposite chamfers 28 of the entrance 27 of the incision 23 are used to facilitate the clip-in process. The guide devices 24 and thus of course also the tabs 21 carrying the axes 22 Adjacent segments 11 are laterally offset from one another in order to enable a compact construction.

Wenn nun eine abgebrochene Pfeilspitze aus einem Segment 11 der Wurfpfeil-Scheibe 8 in der Betriebsposition des Wurfpfeil-Spielgerätes enfternt werden muß, dann kann nach dem Aufschließen des Schlüssel-Schlosses 7 die Fronttür 3 in die in Fig. 1 dargestellte Öffnungsposition verschwenkt werden. Anschließend ist die Verschlußeinrichtung 19 an der Rückwand der Fronttür 1 zu lösen und dann die die Schaltermatrix 13 aufnehmende Trägerplatte 15 in die in Fig. 1 veranschaulichte Abklapposition zu bringen. Damit ist das die abgebrochene Pfeilspitze enthaltende Segment 11 der Wurfpfeilscheibe 8 von der Rückseite her frei zugänglich, so daß die abgebrochene Pfeilspitze leicht aus dem Segment herausgedrückt werden kann, wobei das Segment 11 weder nach vorne aufgrund des Zusammenspiels der Achsen 22 mit den Einschnitten 23 in den radialen Rippen 9 noch nach hinten aufgrund der Führungseinrichtungen 24 aus der Wurfpfeil-Scheibe 8 herausfallen kann. Gleichzeitig können ggfls. beschädigte Segmente und/oder die Schaltermatrix 13 schnell ausgewechselt werden. Nach Beendigung der vorgenannten Arbeiten ist lediglich die Trägerplatte 15 mit der Schaltermatrix 13 wieder in ihre Ausgangsstellung zurückzuklappen, mittels der Verschlußeinrichtung 19 in ihrer Position zu fixieren und die Fronttür 3 mittels des SchlUssel-Schlosses 7 mit dem Gehäuse 2 zu verschließen, wodurch das Wurfpfeil-Spielgerät wieder spielbereit ist.If a broken arrowhead has to be removed from a segment 11 of the dart disk 8 in the operating position of the dart game device, then after unlocking the key lock 7 the front door 3 can be pivoted into the opening position shown in FIG. 1. Then the locking device 19 on the rear wall of the front door 1 is to be released and then the carrier plate 15 receiving the switch matrix 13 into that illustrated in FIG. 1 Bring down position. Thus the segment 11 of the dartboard 8 containing the broken arrow head is freely accessible from the rear, so that the broken arrow head can be easily pushed out of the segment, the segment 11 neither moving forward due to the interaction of the axes 22 with the incisions 23 in the radial ribs 9 can still fall out of the arrow disc 8 due to the guide devices 24. At the same time, if necessary. damaged segments and / or the switch matrix 13 can be replaced quickly. After completion of the aforementioned work, the support plate 15 with the switch matrix 13 is only to be folded back into its starting position, fixed in position by means of the locking device 19 and the front door 3 locked with the housing 2 by means of the key lock 7, whereby the dart arrow Game device is ready to play again.
