Abstract

The invention relates to a trigger system which is simple and of small size for a cross-bow, allowing the release of a bolt by a low pressure on the trigger, even if it is under a very high tension. The system comprises a pawl 3 which retains the bolt 8 while bearing on the trigger 1; by causing the latter to swivel, the pawl 3 pivots on its spindle 7 and retracts while releasing the bolt 8. The immobilization of the trigger 1 by the safety device 5 ensures the locking of the complete mechanism. The insertion of the bolt 8 in the butt causes the retraction of the arming rocker 2 which carries the spindle 7 of the pawl 3 which then engages in the notch of the bolt 8. This system can be applied to cross-bows whatever their method of propulsion may be, and whenever a release from a high tension (sail board harness, safety belt, towing cable etc) is required by means of a very low force.

Description

présente invention concerne un système de détente.. the present invention relates to an expansion system.

pour arbalète sous-marine.for underwater crossbow.

Dans les systèmes actuellement répandus, la partie mécanique fait appel à de nombreuses pièces, axes et ressorts de plus tous ces éléments étant souvent séparés occupent une partie importante de la crosse. In currently widespread systems, the mechanical part uses many parts, axes and springs in addition all these elements are often separated occupy a significant part of the stock.

Particularités qui ont une incidence évidente sur le cout de fabrieation et le poids de l'ensemble.  Particularities which have an obvious impact on the cost of manufacture and the weight of the set.

En outre une trop grande complexité du mécanisme va a l'encontre de sa fiabilité. In addition, too great a complexity of the mechanism goes against its reliability.

Dans le système selon l'invention la partie mécanique etant très simple du fait qu'à part la sécurité elle ne eomporte que trois pièces mobiles (détente, bascule d'armement, gachette), deux axes et un seul ressort assurant conjointement le rappel des trois pièces précitées. In the system according to the invention the mechanical part being very simple due to the fact that apart from safety it only has three moving parts (detent, arm lever, trigger), two axes and a single spring jointly ensuring the recall of the three aforementioned pieces.

Cette simplicité permettra une réalisation à moindre frais, tandis que la compacité de l'ensemble (y compris la sécurité, jouxtant le mécanisme)-, permettra d'améliorer considérablement la flotabilité de l'arbalète à l'aide de matériaux légers logés dans les parties restées ainsi libres de la crosse.  This simplicity will allow a realization at a lower cost, while the compactness of the whole (including safety, adjoining the mechanism) -, will considerably improve the buoyancy of the crossbow using light materials housed in the parts thus left free of the stick.

De plus autour du très petit volume occupé on pourra donner à la crosse toute forme anatomique ou esthétique sou haitée, laissant ainsi libre cours à l'imagination du "désigner"
Dans la planche annexée, la figure 1 est une vue en coupe de la crosse.et la figure deux-un éclaté du mécanisme.In addition, around the very small occupied volume, we can give the stock any anatomical or aesthetic shape desired, thus giving free rein to the imagination of the "designer"
In the accompanying plate, Figure 1 is a sectional view of the butt. And Figure two-an exploded view of the mechanism.

Tel qu'il est représenté, sécurité 5 mise et flèche 8 engagée, le système comporte une détente 1 sur laquelle vient s'appuyer la longue partie inférieure de la gachette 3 qui retiens dans sa courte partie supérieure la flèche 8 par l'é- videment prévu pour cet usage. As shown, safety 5 put and arrow 8 engaged, the system comprises a trigger 1 on which the long lower part of the trigger 3 rests which retains the arrow 8 in its short upper part by the drain intended for this use.

TIR: Une fois la sécurité 5 dégagée, la détente 1 en pivotant en 10 sur son axe 6, libère la gachette 3 qui pivotant en 11 sur son axe 7, s'efface, laissant s'échapper en 12 la flèche 8 propulsée par son moyen propre (ressort ou sandow), à ce moment le ressort 4 remet à leur place initiale les t trois pièces du mécanisme. SHOOTING: Once the safety 5 released, the trigger 1 by pivoting at 10 on its axis 6, releases the trigger 3 which pivots at 11 on its axis 7, is erased, letting escape at 12 the arrow 8 propelled by its clean means (spring or bungee cord), at this time the spring 4 returns the three parts of the mechanism to their original place.

ASdEMENT: Lors de l'armement (sécurité mise ou non), l'introduction de la flèche 8 dans son logement fait pivoter vers le bas en 9 la bascule d'armement 2 sur l'axe 6t à la la fin de cette intFoduction le ressort 4 remet à leur place bascule 2 et gachette 3 (haut bloqué dans l'évidement de la flèche 8, bas appuyé sur la détente 1)
SECURITE: l'immobilisation de la détente l par la par; tie-haute de la sécurité 5 assure automatiquement le blocage de tout le système, tandis que sa partie basse en position ouverte, limite la course de la détente 1 et sert également de point d'appui à tout le mécanisme.ADEQUATELY: When cocking (security put or not), the introduction of the arrow 8 in its housing makes the cocking lever 2 pivot on the 9 axis 6t at the end of this intFoduction spring 4 puts rocker 2 and trigger 3 in their place (top blocked in the recess of arrow 8, bottom pressed on trigger 1)
SAFETY: immobilization of the trigger l by par; tie-haute de la sécurité 5 automatically locks the entire system, while its lower part in the open position limits the travel of the trigger 1 and also serves as a fulcrum for the entire mechanism.

Cette invention peut s'appliquer aux arbalbtes quel que soit leur mode de propulsion, ainsi qu'à chaque fois que l' on aura à se libérer par un très faible effort d'une forte tension. (harnais de planche à voile, ceinture de sécurité, cable de remorquage etc, etc...)  This invention can be applied to crossbows whatever their mode of propulsion, as well as each time that one will have to free himself by a very weak effort of a strong tension. (windsurfing harness, seat belt, towing cable etc, etc ...)
