Abstract

It is characterised by the combination, on the one hand, of a top oscillation point detent 5 provided close to the pivoting pin with notching (catching means) 6 retaining a sector of a part 1 which rocks on an eccentric shaft 8 and whose lever arm 10 bears on the shoulder 11 of the trigger 12 which also oscillates and, on the other hand, with a pivoting part 15 which ensures both the safety, the release and the adjustment of the travel of the detent. Its object is to confer on the detent complete flexibility of control whilst reducing the size of the mechanism and enabling, by means of a single rotary part, the adjustment of the detent, as well as the safety, to be ensured.

Description

L'objet de l'invention concerne un dispositif de gâchette à double échappement pour armes de chasse sous-marine. The object of the invention relates to a double exhaust trigger device for spearfishing weapons.

Il a pour but de conférer à la détente une extrême souplesse de commande tout en diminuant 1 'encombrement du mécanisrne et de permettre d'assurer, par une pièce rotative unique, le réglage de la détente, ainsi que la sécurité. It aims to give the trigger an extreme flexibility of control while reducing one footprint of the mechanisrne and to ensure, by a single rotating part, the adjustment of the trigger, as well as safety.

Les dispositifs connus de ce genre, utilisent des systèmes de bras de levier à liaison directe entre la détente et la gâchette, ce qui exige pour cette dernière une grande amplitude de mouvement. Ce mouvement de la gâchette s 'effectue de bas en haut, de sorte que le cran de retenue intégré à la détente, se trouve éloigné du point d' appui qui tient lieu d' axe de rotation. Cette disposition occasionne une certaine résistance à la pression du doigt sur la détente et, en conséquence, un manque de précision au moment du tir. Known devices of this kind use lever arm systems with direct connection between the trigger and the trigger, which requires the latter a large range of movement. This movement of the trigger is effected from bottom to top, so that the retaining notch integrated in the trigger, is distant from the fulcrum which acts as the axis of rotation. This arrangement causes a certain resistance to the pressure of the finger on the trigger and, consequently, a lack of precision when firing.

Le dispositif suivant l'invention supprime ces inconvénients et confère une très grande souplesse de corr!mande par une double démultiplication de l ' effort de traction sur la détente et par la réduction de l'encombrement des pièces constituant le mécanisme, et enfin, par l'inversion des mouvements qui s'effectuent dans un espace minime. The device according to the invention eliminates these drawbacks and confers a very great flexibility of correction by a double reduction of the tensile force on the trigger and by the reduction in the size of the parts constituting the mechanism, and finally, by the inversion of the movements which take place in a minimal space.

Il se caractérise par la combinaison, d'une part d'une détente à point oscillation haut, pourvu près de l'axe de pivotement, d'un crantage retenant un secteur d'une pièce basculant sur un arbre excentré et dont - le bras de levier prend appui sur l'épaulement de la gâchette également oscillante et, d'autre part avec une pièce pivotante assurant à la fois la sécurité, la libération et le réglage de la course de la détente. It is characterized by the combination, on the one hand of a trigger with a high oscillation point, provided near the pivot axis, of a notch retaining a sector of a part rocking on an eccentric shaft and of which - the arm lever rests on the shoulder of the trigger also oscillating and, on the other hand with a pivoting part ensuring both safety, release and adjustment of the travel of the trigger.

Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l ' invention
La figure 1 représente le dispositif dans son ensemble vu en élévation et en position de verrouillage.
In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows the device as a whole seen in elevation and in the locked position.

Les figures 2 et 3 montrent schématiquement les gâchettes, leviers et détentes en position d'armement et de tir. Figures 2 and 3 schematically show the triggers, levers and detents in the cocking and firing position.

Lc flécanisme simplifié est constitué par une détente 1 formée par une pece pro filée avec évidemment 2 sur sa face arrière recevant un ressort à compression 3 la maintenant dans sa position de verrouillage. The simplified mechanism consists of a detent 1 formed by a profiled piece with obviously 2 on its rear face receiving a compression spring 3 keeping it in its locked position.

Cette détente se prolonge par un bras 4 légèrement coudé et, à la partie supérieure duquel se trouve l'axe de rotation 5. This expansion is extended by a slightly bent arm 4 and, at the top of which is the axis of rotation 5.

La face interne de cette détente est crantée 6 et reçoit l'extrémité de la pièce pivotante oscillante autour de son axe excentré 8. Le secteur 7 forme un bras de levier recevant la traction du ressort 9 de rappel qui le ramène dans sa position initiale après le départ de la flèche 17. The internal face of this trigger is notched 6 and receives the end of the pivoting part oscillating around its eccentric axis 8. The sector 7 forms a lever arm receiving the traction of the return spring 9 which returns it to its initial position after the start of arrow 17.

Le secteur 13 de la pièce basculante formant un bras rie levier plus court, est retenu par l'épaulement 11 de la gâchette 12 basculant autour de son axe 13 et subissant la traction du ressort 14 de rappel. The sector 13 of the rocking part forming a shorter lever arm, is retained by the shoulder 11 of the trigger 12 rocking about its axis 13 and undergoing the traction of the return spring 14.

La pièce pivotante 15 sert à la fois de verrcuillage de sécurité et de réglage de course de détente. The pivoting part 15 serves both as a safety lock and as a trigger stroke adjustment.

Elle est positionnée dans un logement de forme carrée 16 pratiqué à la partie inférieure interne de la détente 1, un de ses côtés est partiellement ouvert de façon qu'au moment du tir la détente puisse passer sous son axe de rotation. It is positioned in a square-shaped housing 16 formed in the internal lower part of the trigger 1, one of its sides is partially open so that when the trigger is fired can pass under its axis of rotation.

Cette pièce 15 forme un levier manoeuvrable de I' exté- rieur de la crosse. Dans sa position S l'arme est verrouillée, dans sa position N le tir est libre sans modification de la course de la détente. Enfin, dans la position W intermédiaire, le levier provoque un raccourcissement notable de la course de la détente qui bascule autour de son axe 5, dans le sens de la flèche A. This part 15 forms a lever which can be operated from the outside of the stick. In its position S the weapon is locked, in its position N the shooting is free without modification of the stroke of the trigger. Finally, in the intermediate position W, the lever causes a notable shortening of the travel of the trigger which swings around its axis 5, in the direction of arrow A.

En position d ' ar .ement figure 2, la gâchette 12 est repoussée par la flèche d'avant en arrière et ramenée dans sa position initiale par le ressort de rappel 1G, dès l'instant où telle se trouve face au crantage de la flèche. Toutes les autres pièces du système sont immobiles.  In the position of ar .ement Figure 2, the trigger 12 is pushed by the arrow back and forth and returned to its initial position by the return spring 1G, from the moment when it is facing the notch of the arrow . All other parts of the system are stationary.

Au moment du tir, le secteur 7 de la pièce pivotante bascule vers le bas et, est ramené dans sa position initiale par la traction du ressort 9, ce qui a pour effet de ramener du même coupla gâchette 12 en position d'armement, par la poussée exercée par le secteur sur 1'épaulèment 11. At the time of the firing, the sector 7 of the pivoting part swings down and is returned to its initial position by the pulling of the spring 9, which has the effect of bringing the same trigger coupla 12 into the cocking position, by the thrust exerted by the sector on the shoulder 11.

L'ensemble de ce mécanitne à effet compensé, démultiplie l'effort entre la détente et le verrou. Il assure une souplesse de départ améliorée, ainsi qu'une sécurité accrue avec une meilleure résistance à l'usure, grâce au faible effort effectué par la pièce intermédiaire 7 sur le bras de détente, contrairement aux systèmes classiques qui mettent directement en relation les gâchettes et les détentes, ou en utilisant des leviers de grande amplitude. The whole of this compensated effect mechanism multiplies the effort between the trigger and the lock. It provides improved starting flexibility, as well as increased safety with better wear resistance, thanks to the low effort made by the intermediate piece 7 on the trigger arm, unlike conventional systems which directly connect the triggers and detents, or using large levers.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d ' ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de 1' invention qui viens d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture, without thereby changing the general design of the invention which has just been described.
