L'objet de l'invention se rapporte notamment au secteur technique de l'armement.The object of the invention relates in particular to the technical armaments sector.

Au cours de la mise au point du fusil de chasse qui a fait l'objet du document FR-A-2455263 dont le déposant est également titulaire et sur lequel se base le préambule de la revendication 1, il est apparu nécessaire d'apporter des modifications dans les différents mécanismes afin d'améliorer les performances et la sécurité.During the development of the hunting rifle which was the subject of document FR-A-2455263 of which the applicant is also the holder and on which the preamble of claim 1 is based, it appeared necessary to bring modifications in the various mechanisms in order to improve performance and security.

On rappelle succinctement que, suivant la revendication 1 de ce document, le dispositif est constitué d'une came-barrette commandée en pivotement par la queue arrière du percuteur inférieur et sollicitée par une détente axée en bout de la gâchette supérieure; ladite came-barrette rappelée vers l'avant par un ressort, comportant en épaisseur une ouverture équerrée, traversée par un axe transversal, et dont la branche horizontale permet son pivotement autour de l'axe solidaire de la gâchette supérieure, en vue de son blocage en hauteur lors du tir du premier coup, tandis que la branche verticale autorise le libre coulissement en hauteur de ladite came-barrette en vue du tir du deuxième coup et après l'effacement de la queue du percuteur inférieur; des moyens adaptables à ladite came-barrette pour autoriser soit la mise en détente unique non sélective, soit la mise en double détente, avec une détente à double effet non sélective, soit la mise en détente unique sélective du coup à tirer, soit la mise en double détente indépendante.It is briefly recalled that, according to claim 1 of this document, the device consists of a cam-bar pivotally controlled by the rear tail of the lower striker and urged by a trigger centered at the end of the upper trigger; said cam-bar biased towards the front by a spring, having in thickness a squared opening, crossed by a transverse axis, and the horizontal branch of which allows its pivoting around the axis integral with the upper trigger, in order to block it in height during the firing of the first shot, while the vertical branch allows the free sliding in height of said cam-bar for the firing of the second shot and after the erasure of the tail of the lower striker; means adaptable to said cam-bar for authorizing either the non-selective single trigger, or the double trigger, with a non-selective double-trigger trigger, or the selective single trigger of the shot, or the setting in double independent trigger.

Suivant une première caractéristique de l'invention, la came-barrette est établie à sa base et suivant sa face arrière avec une fente circulaire ouverte concentrique à l'axe-pivot fixé sur l'extrémité de la gâchette supérieure en vue de coopérer en combinaison avec la branche horizontale, de son ouverture équerrée, avec un deuxième axe transversal solidaire de la bascule, de manière à assurer un double verrouillage vertical de ladite came-barrette, évitant tout départ inopiné du percuteur supérieur lors du premier coup correspondant au canon inférieur.According to a first characteristic of the invention, the cam-bar is established at its base and along its rear face with an open circular slot concentric with the pivot axis fixed on the end of the upper trigger in order to cooperate in combination with the horizontal branch, its squared opening, with a second transverse axis secured to the rocker, so as to ensure a double vertical locking of said cam-bar, preventing any unexpected departure of the upper striker during the first shot corresponding to the lower barrel.

Une caractéristique avantageuse se trouve dans le fait que la came-barrette est sollicitée vers l'avant par une des branches d'un ressort en épingle prenant appui de par sa branche opposée sur l'entretoise arrière de la bascule, et centré sur un axe transversal solidaire de la bascule.An advantageous characteristic is found in the fact that the cam-bar is urged forward by one of the branches of a hairpin spring bearing by its opposite branch on the rear spacer of the rocker, and centered on an axis transverse integral with the scale.

Suivant une autre caractéristique préférée, le levier de mise en sûreté forme à sa base un profil arrondi avec deux talons qui coopèrent avec l'axe transversal de la fente circulaire ouverte de la came-barrette, en vue d'assurer la butée de la sûreté dans les positions extrêmes de dégagement et de mise en sûreté.According to another preferred characteristic, the safety lever forms at its base a rounded profile with two heels which cooperate with the transverse axis of the open circular slot of the cam-bar, in order to ensure the safety stop. in the extreme positions of release and safety.

Suivant une autre caractéristique avantageuse, le bec d'armement de chaque gâchette présente une tête circulaire se raccordant à sa base avec un étranglement pour s'engager et se centrer dans la creusure complémentaire du percuteur en vue d'assurer une portée circulaire de crochetage auto-centreuse en position d'armement.According to another advantageous characteristic, the arming spout of each trigger has a circular head connecting to its base with a constriction to engage and center in the complementary recess of the striker in order to ensure a circular self-picking range. -centrer in cocking position.

Suivant une autre caractéristique préférée, l'axe de déplacement de la tige du percuteur se situe après armement parallèlement à l'axe fictif reliant le centre de la tête circulaire de la gâchette à son axe d'articulation.According to another preferred characteristic, the axis of movement of the striker rod is located after arming parallel to the imaginary axis connecting the center of the circular head of the trigger to its axis of articulation.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous des formes non limitatives de réalisation illustrées aux figures des dessins.In order to make the object of the invention more concrete, it is now described in nonlimiting embodiments illustrated in the figures of the drawings.

On rappelle que selon le document FR-A-2 455 263, le percuteur inférieur 39 coopère en poussée de par sa queue arrière 39' sur une came-barrette mobile 40 avec une fente verticale 40' à son extrémité supérieure pour chevaucher un axe pivot 41 fixé transversalement en bout de la gâchette supérieure 42.It will be recalled that according to document FR-A-2 455 263, the lower striker 39 cooperates in pushing by its rear tail 39 'on a movable bar-cam 40 with a vertical slot 40' at its upper end to overlap a pivot axis 41 fixed transversely at the end of the upper trigger 42.

Ladite came-barrette 40 est en outre établie dans son épaisseur avec une ouverture 402 en forme d'équerre pour l'engagement à coulissement d'un axe transversal 43 solidaire du côté latéral de la bascule ou de la plaque-platine 44.Said cam-bar 40 is furthermore established in its thickness with an opening 40 2 in the form of a square for the sliding engagement of a transverse axis 43 secured to the lateral side of the rocker or of the plate-plate 44.

La partie inférieure avant de la came-barrette 40 est arrondie pour se raccorder en bout à un bec 403 disposé en regard de la face supérieure arrondie 45' de la détente unique 45, elle-même articulée autour de l'axe 46.The lower front part of the cam-bar 40 is rounded so as to be connected at the end to a spout 40 3 disposed opposite the rounded upper face 45 ′ of the single trigger 45, itself articulated around the axis 46.

Selon la présente invention, la came-barrette 40 comporte également dans son épaisseur une fente circulaire 404 disposée au-dessous de l'ouverture 402 et ouverte suivant l'arrière. Cette fente 404 concentrique à l'axe-pivot 41 coulisse librement sur un deuxième axe transversal 47 également solidaire du côté latéral de la bascule ou de la plaque-platine 44, et se raccorde directement avec le bec 403.According to the present invention, the cam-bar 40 also has, in its thickness, a circular slot 40 4 arranged below the opening 40 2 and open along the rear. This slot 40 4 concentric with the pivot axis 41 slides freely on a second transverse axis 47 also integral with the lateral side of the rocker or of the plate-plate 44, and is connected directly with the spout 40 3 .

Une axe-support 48 solidaire du côté latéral de la bascule ou de la plaque-platine 44 et disposé à l'arrière de la came-barrette 40, autorise l'engagement des spires successives d'un ressort en épingle 49 travaillant en torsion, dont l'une des branches 49' exerce un appui permanent sur la face arrière de ladite came 40, tandis que la branche opposée est butée sur l'entretoise arrière de la bascule.A support pin 48 secured to the lateral side of the rocker or of the plate-plate 44 and disposed at the rear of the cam-bar 40, authorizes the engagement of successive turns of a pin spring 49 working in torsion, one of which branches 49 'exerts permanent support on the rear face of said cam 40, while the opposite branch is abutted on the rear spacer of the rocker.

Selon ces dispositions constructives, dans le cas du fonctionnement du dispositif en détente unique non sélective, l'on conçoit que, lors de l'armement, comme indiqué dans le document FR-A-2 455 263, la queue arrière 39' du percuteur inférieur 39 repousse la came-barrette 40 qui oscille vers l'arrière (flèches F) autour de l'axe-pivot 41, à l'encontre de l'effort exercé par le ressort 49.According to these constructive provisions, in the case of the operation of the non-selective single trigger device, it is understood that, during arming, as indicated in the document FR-A-2 455 263, the rear tail 39 'of the striker lower 39 pushes back the cam-bar 40 which oscillates rearward (arrows F) around the pivot axis 41, against the force exerted by the spring 49.

De ce fait, la branche horizontale de l'ouverture 402 s'engage sur l'axe 43, ainsi que la fente circulaire 404 sur l'axe 47 de manière à assurer un double verrouillage en hauteur de la came-barrette 40.Therefore, the horizontal branch of the opening 40 2 engages on the axis 43, as well as the circular slot 40 4 on the axis 47 so as to ensure a double locking in height of the cam-bar 40.

On considère que ce double verrouillage assure une sécurité parfaite, évitant tout départ inopiné du deuxième coup supérieur en cas d'usure de l'ouverture équerrée 402 ou d'un engagement incomplet sur sa branche horizontale. On remarque en effet que, par suite du rayon important de la fente circulaire 404, le verrouillage intervient dès le début de l'oscillation de la came-barrette 40.It is considered that this double locking ensures perfect security, avoiding any unexpected departure of the second top stroke in the event of wear of the square opening 40 2 or of an incomplete engagement on its horizontal branch. It is in fact noted that, owing to the large radius of the circular slot 404, the locking takes place from the start of the oscillation of the cam-bar 40.

L'appui exercé sur la détente unique 45 permet d'une part le basculement de la gâchette inférieure 50 par le dégagement et le rappel du percuteur inférieur 39 en vue du tir du premier coup, comme illustré fig. 1, et également l'appui de sa face supérieure arrière arrondie 45' sur le bec 403 en vue du maintien en position de recul et de double verrouillage de la came-barrette 40 pour éviter le tir inopiné du deuxième coup comme illustré en fig. 2.The support exerted on the single trigger 45 allows on the one hand the tilting of the lower trigger 50 by the release and the return of the lower striker 39 for the first shot, as illustrated in FIG. 1, and also the support of its rounded rear upper face 45 ′ on the spout 40 3 in order to maintain the recoil position and double locking of the cam-bar 40 to avoid the unexpected firing of the second shot as illustrated in fig . 2.

Comme indiqué dans le document FR-A-2 455 263, lorsque l'usager relâche l'appui manuel sur la détente 45, la came-barrette 40 est alors sollicitée contrairement vers l'avant (flèche F1) par la détente du ressort 49, de manière à osciller autour de l'axe-pivot 41 pour présenter d'une part la branche verticale de l'ouverture équerrée 402 en regard de l'axe 43, et d'autre part, la fente circulaire 404 en position de dégagement par rapport à l'axe 47. L'appui exercé à nouveau sur la détente permet, de par sa partie supérieure arrière agissant sur le bec 403, d'obtenir le mouvement vertical de la came-barrette 40 en vue du basculement de la gâchette supérieure 42 pour le tir du deuxième coup.As indicated in document FR-A-2 455 263, when the user releases the manual support on the trigger 45, the cam-bar 40 is then urged unlike forward (arrow F1) by the trigger of the spring 49 , so as to oscillate around the pivot axis 41 to present on the one hand the vertical branch of the squared opening 40 2 opposite the axis 43, and on the other hand, the circular slot 40 4 in position of clearance with respect to the axis 47. The pressure exerted again on the trigger makes it possible, by its rear upper part acting on the spout 40 3 , to obtain the vertical movement of the cam-bar 40 for tilting of the upper trigger 42 for firing the second shot.

Il est bien évident que ces caractéristiques s'appliquent également comme indiqué dans le document FR-A-2 455 263, dans le cas d'un dispositif à deux détentes, avec l'une ou l'autre fonctionnant en détente double effet non sélective et également dans le cas d'un dispositif avec détente unique sélective du coup à tirer et d'un dispositif avec détente classique et indépendante.It is obvious that these characteristics also apply as indicated in document FR-A-2 455 263, in the case of a device with two detents, with one or the other operating in non-selective double-effect expansion. and also in the case of a device with a single selective trigger release and a device with conventional and independent trigger.

Selon la présente invention, le levier de sûreté 51 articulé autour de l'axe 43 et disposé au-dessous de la came-barrette 40 forme à sa base un secteur arrondi 51' qui se présente en regard de l'axe 47 et est muni de deux talons espacés 512 et 513 qui coopèrent respectivement en butée avec ledit axe 47 en vue de limiter dans les deux sens les déplacements du levier du sûreté 51 suivant les positions de dégagement ou de mise en sûreté.According to the present invention, the safety lever 51 articulated around the axis 43 and arranged below the cam-bar 40 forms at its base a rounded sector 51 'which is opposite the axis 47 and is provided two spaced heels 51 2 and 51 3 which cooperate respectively in abutment with said axis 47 in order to limit in both directions the movements of the safety lever 51 according to the release or safety positions.

On remarque également que chaque gâchette 42 et 50 est établie avec un bec d'armement, sous forme d'une tête arrondie 42', 501, avec, à l'arrière et à sa base, un étanglement 422-502, de manière à former une proémincence qui s'engage et se centre périphériquement dans une creusure complémentaire 392 et 521 du percuteur correspondant 39 ou 52.We also note that each trigger 42 and 50 is established with an arming spout, in the form of a rounded head 42 ′, 50 1 , with, at the rear and at its base, a throttle 42 2- 50 2 , so as to form a prominence which engages and centers itself peripherally in a complementary recess 39 2 and 52 1 of the corresponding striker 39 or 52.

On remarque également que l'axe fictif reliant le centre de la tête 42'-50' à l'axe de pivotement 53-54 de chaque gâchette, est disposé dans l'axe de la tige coulissante du percuteur correspondant 39-52, de manière à assurer un auto-centrage et un crochetage parfait.We also note that the fictitious axis connecting the center of the head 42'-50 'to the pivot axis 53-54 of each trigger, is arranged in the axis of the sliding rod of the corresponding striker 39-52, so as to ensure perfect self-centering and picking.

Il est bien évident que cette disposition assurant une sécurité d'armement peut s'appliquer à toute autre arme et à tout percuteur coulissant ou basculant.It is obvious that this provision ensuring arming security can be applied to any other weapon and to any sliding or tilting striker.
