It also comprises an assembly (V) for exciting the mat (VII) which can be designed from high resistance materials. <IMAGE>

Description

La présente invention concerne un dispositif de contrôle des touches don­nées et reçues à l'occasion des assauts en escrime.The present invention relates to a device for controlling the keys given and received during fencing attacks.

Ce dispositif a l'avantage de s'affranchir de toute liaison ohmique entre les tireurs et, de ce fait, élimine les contraintes inhérentes à la mise en place des différents câblages et à l'utilisation de matériels dont la fiabilité n'est pas à toute épreuve, tels que les enrouleurs notamment ; d'autre part il donne une dimension supplémentaire à l'escrime en autori­sant des déplacements dans le plan et non plus suivant un axe et, laisse prévoir des combats au cours desquels plusieurs adversaires peuvent s'af­fronter.This device has the advantage of eliminating any ohmic connection between the shooters and, therefore, eliminates the constraints inherent in the establishment of the various cables and the use of equipment whose reliability is not to any test, such as the reels in particular; on the other hand it gives an additional dimension to fencing by authorizing displacements in the plane and no longer along an axis and, lets predict combats during which several adversaries can confront each other.

En outre l'une des originalités de sa conception rend possible, voire mê­me incite à l'utilisation de matériaux à faible conduction électrique, c'est-à-dire à résistance élevée pour la confection des pistes et des cui­rasses en particulier. C'est le cas de substances employées spécialement dans le contrôle de l'électricité statique telles que mousses, caoutchouc, textiles légèrement conducteurs présentant des résistances électriques de plusieurs dizaines de kilo-ohm.In addition, one of the original features of its design makes it possible, or even encourages, the use of materials with low electrical conduction, that is to say with high resistance for making tracks and breastplates in particular. This is the case of substances used specially in the control of static electricity such as foams, rubber, slightly conductive textiles having electrical resistances of several tens of kilo-ohms.

Le principe de l'invention repose sur l'utilisation de phénomènes électri­ques périodiques dont les fréquences sont soit basses, soit élevées sui­vant que ce signal électrique est véhiculé par un support conducteur ou propagé sous forme d'ondes radioélectriques. De plus le signal est codé pour limiter au maximum les risques d'interférence dans le cas où plusieurs dispositifs sont mis en oeuvre dans le même site.The principle of the invention is based on the use of periodic electrical phenomena whose frequencies are either low or high depending on whether this electrical signal is carried by a conductive support or propagated in the form of radio waves. In addition, the signal is coded to minimize the risk of interference in the event that several devices are used on the same site.

Les signaux précités sont échangés lors de la touche, entre les deux en­sembles portés par les escrimeurs, ensembles compatibles entre eux, en ce sens que le récepteur de l'un est calé pour recevoir et décoder le signal élaboré par l'émetteur opposé et inversement. Cette réalisation nécessite la mise en oeuvre d'un duplex radioélectrique à partir de deux réseaux dis­tincts travaillant sur des fréquences H.F. ou V.H.F. et des codes différents. A titre d'exemple, l'application de ces principes sera décrit pour la réa­lisation d'un contrôleur de touches données et reçues lors des assauts à l'épée. Il est bien évident, qu'à quelques variantes près, dues aux parti­cularités de chaque arme, ces principes peuvent être adaptés au fleuret voire même au sabre.The aforementioned signals are exchanged during the touch, between the two assemblies carried by the fencers, assemblies compatible with each other, in the sense that the receiver of one is calibrated to receive and decode the signal produced by the opposite transmitter and vice versa . This achievement requires the implementation of a radio duplex from two separate networks working on frequencies H.F. or V.H.F. and different codes. By way of example, the application of these principles will be described for the realization of a controller of keys given and received during assaults with the sword. It is obvious that, with a few variations, due to the particularities of each weapon, these principles can be adapted to foil or even saber.

L'organisation générale du dispositif fait l'objet de la figure 1 sur la­quelle il est possible de distinguer les armes I et I bis, les fils de corps II et II bis, les boîtiers électroniques III et III bis, les systè­mes de matérialisation des touches IV et IV bis comprenant une signalisa­tion lumineuse et sonore, les aériens V (e et r) et V bis (e et r), un ex­citateur de tapis VI générant les signaux F1 et F2 et un tapis VII destiné à représenter la piste où se déroulent les combats, tapis excité par les signaux électriques F1 et F2.The general organization of the device is the subject of FIG. 1 on which it is possible to distinguish the weapons I and I bis, the body wires II and II bis, the electronic boxes III and III bis, the systems for materializing the keys IV and IV bis comprising a light and sound signal, the aerials V (e and r) and V bis (e and r), a carpet exciter VI generating the signals F1 and F2 and a carpet VII intended to represent the track where fighting takes place, carpet excited by electrical signals F1 and F2.

Le boîtier électronique III ( ou III bis ) comme l'indique la figure 2 comprend un générateur et émetteur 31 ainsi qu'un récepteur décodeur 32 d'ondes radioélectriques travaillant tous deux sur des fréquences H.F. ou V.H.F. différentes : la fréquence du récepteur 32 du boîtier III étant a­justée pour recevoir le signal 31 du boîtier III bis lors de la touche et inversement. Ces deux organes principaux ont leur fonction respective d'é­mission et de réception controlée et asservie par un ensemble logique te­nantcompte de certaines contingences matérielles ou physiques et des rè­gles concernant le combat à l'épée en l'occurence. Il s'agit principale­ment :
de l'oscillateur 33 délivrant un signal basse fréquence F1 sur l'arme du ti­reur
- du détecteur 36 de signal basse fréquence F2 émis par l'oscillateur 33 du dispositif adverse ou par l'excitateur de tapis VI, chargé d'inhiber la fonction d'émission de 31 lorsqu'il décelle la présence de ce signal.
- du filtre 37 éliminant les impulsions de fermeture du contact de la poin­te de l'arme dont la durée serait inférieure au délai prévu par le règle­ment en la matière.
- du système 34 de temporisation de l'impulsion du signal reçu et décodé, quimaintient l'affichage de la touche pendant un temps suffisamment long pour que le résultat puisse être perçu et exploité dans de bonnes condi­tions par les tireurs, le public et les arbitres de la rencontre.
- du retardateur 35 de la temporisation précedente dont le signal de sortie est destiné à inhiber l'émetteur 31 : ce retard est également fixé par les règlements.La temporisation de 34 est faite à la réception dans la mesure, bien sûr, où il n'a pas été choisi de temporiser l'émission adverse.The electronic unit III (or III bis) as indicated in FIG. 2 comprises a generator and transmitter 31 as well as a receiver decoder 32 of radio waves both working on different HF or VHF frequencies: the frequency of the receiver 32 of the box III being adjusted to receive the signal 31 from box III bis when the button is pressed and vice versa. These two main organs have their respective function of emission and reception controlled and enslaved by a logical unit taking into account certain material or physical contingencies and the rules concerning sword fighting in this case. These are mainly:
of oscillator 33 delivering a low frequency signal F1 on the gunner's weapon
- The detector 36 of low frequency signal F2 emitted by the oscillator 33 of the opposing device or by the carpet exciter VI, responsible for inhibiting the emission function of 31 when it detects the presence of this signal.
- The filter 37 eliminating the contact closure pulses from the tip of the weapon, the duration of which would be less than the period provided for in the relevant regulations.
- the time delay system 34 for the pulse of the received and decoded signal, which maintains the display of the key for a time long enough for the result to be perceived and used in good conditions by the shooters, the public and the referees of the meeting.
- the self-timer 35 of the previous time delay, the output signal of which is intended to inhibit the transmitter 31: this time delay is also fixed by the regulations. The time delay of 34 is made on reception insofar as, of course, it does not was not chosen to delay the opponent's broadcast.

Le fonctionnement du dispositif est simple. Lors de la touche, la tête de pointe de l'arme qui se comporte comme un bouton poussoir, normalement ou­vert au repos, ferme le circuit qui active l'émetteur 31 ; celui-ci déli­vre son signal codé H.F. ou V.H.F. dans la mesure où sa fonction n'est pas inhibée par la présence de la grandeur électrique a (figure 2). Le signal rayonné est reçu decodé, temporisé et affiché par l'appareil adverse, c'est-­à-dire par l'ensemble porté par l'escrimeur qui vient d'être touché.The operation of the device is simple. When touched, the point head of the weapon which behaves like a push button, normally open at rest, closes the circuit which activates the transmitter 31; the latter delivers its coded signal H.F. or V.H.F. insofar as its function is not inhibited by the presence of the electrical quantity a (FIG. 2). The radiated signal is received decoded, timed and displayed by the opposing device, that is to say by the assembly carried by the fencer who has just been hit.

Toutefois cette émission lors de la touche n'a pas lieu si :
- elle est trop courte et de ce fait filtrée par 37
- la tête de pointe de l'arme qui provoque la touche est actionnée sur une surface parcourue par la fréquence F2
- l'émission est inhibée par la présence de l'affichage d'une touche, a­près le retard apporté par 35However, this transmission during the touch does not take place if:
- it is too short and therefore filtered by 37
- the point head of the weapon which causes the key is actuated on a surface traversed by the frequency F2
- the transmission is inhibited by the presence of a key display, after the delay brought by 35

La description détaillée des divers éléments susdits tels que oscillateurs les émetteurs ou récepteurs qu'ils soient de type modulation de fréquence ou d'amplitude ou de phase, les décodeurs, les filtres et les temporisa­teurs ne revêt aucun intérêt particulier pour la présente invention, ces fonctions peuvent être réaliséesde différentes manières et les circuits in­tégrés utilisés dans ces domaines ne manquent pas.The detailed description of the various aforementioned elements such as oscillators the transmitters or receivers, whether of the frequency or amplitude or phase modulation type, the decoders, the filters and the timers are of no particular interest for the present invention, these functions can be carried out in different ways and the integrated circuits used in these fields is not lacking.

Comme l'indique la figure 3, il est possible de réaliser une variante du dispositif en renvoyant l'affichage IV et IV bis sur un appareil central VIII doté de deux récepteurs 81 et 82 recevant les signaux respectifs des émetteurs 31 de III et III bis des deux escrimeurs qui s'affrontent.As shown in Figure 3, it is possible to make a variant of the device by returning the display IV and IV bis to a central device VIII provided with two receivers 81 and 82 receiving the respective signals from the transmitters 31 of III and III bis of the two fencers who clash.

Il faut mentionner également que la discrimination des zones à traitement particulier peut-être faite de manière inverse à celle décrite, c'est-à-­dire en excitant lors de la touche, la tête de pointe de l'arme par le si­gnal basse fréquencequi se propagerait sur la surface conductrice au moment de la pression de la pointe de l'arme sur cette dernière.It should also be mentioned that the discrimination of the zones with particular treatment can be made in a reverse manner to that described, that is to say by exciting when touching, the point head of the weapon by the low frequency signal which would propagate on the conductive surface when the point of the weapon is pressed on it.

En résumé, les équipements faisant l'objet de la présente description bou­leversent l'environnement matériel de l'escrime en supprimant les contrain­tes inhérentes à l'utilisation d'une liaison filaire entre les escrimeurs et en supprimant l'emploi de matériels dont la fiabilité est mise à rude épreuve par les déplacements fréquents et brusques des tireurs. En outre, l'injection de basses fréquences dans le tapis de sol permet d'éviter l'u­tilisation de piste métallique de mise en place pénible et dont la contex­ture rugueuse à des effets néfastes sur la longévité des chaussures et fa­vorise l'emploi de matériaux modernes plus souples, plus esthétiques pou­vant être intégré plus harmonieusement dans l'environnement matériel de l'escrime.In summary, the equipment that is the subject of this description disrupts the physical environment of fencing by removing the constraints inherent in the use of a wired link between the fencers and by eliminating the use of equipment whose reliability is put to the test by the frequent and sudden movements of the shooters. In addition, the injection of low frequencies into the floor mat makes it possible to avoid the use of a painful metal installation track, the rough texture of which has harmful effects on the longevity of the shoes and promotes the use of materials. modern, more flexible, more aesthetic that can be integrated more harmoniously into the material environment of fencing.

Enfin, la mise en oeuvre de ces appareillages ne demande que très peu de modifications, le seul qui est fortement conseillé est le blindage du fil qui relie les contacts de la tête de pointe de l'arme au fil de corps du tireur : cette modification n'interdit d'ailleurs pas, par la suite, l'u­tilisation de l'arme avec le matériel conventionnel.Finally, the implementation of these devices requires very few modifications, the only one which is strongly recommended is the shielding of the wire which connects the contacts of the point head of the weapon to the body wire of the shooter: this modification does not prohibit, thereafter, the use of the weapon with conventional equipment.
