Description

L'invention concerne un dispositif de support de flèche escamotable pour arcThe invention relates to a retractable bow support device for a bow

On connaît déjà des repose-flèches escamotables, qui sont fixés sur l'âme de l'arc à proximité de la zone de maintien de la flèche, afin de soutenir la flèche lors de la visée, puis de s'escamoter dès que le tireur libère la corde de l'arc. Ces dispositifs évitent que la flèche ne soit déviée de sa trajectoire, particulièrement lorsque l'empennage de la flèche arrive à hauteur du repose-flèche.Retractable arrow rests are already known, which are fixed to the core of the bow close to the arrow holding zone, in order to support the arrow during aiming, then to retract as soon as the shooter releases the string from the bow. These devices prevent the arrow from being deflected from its path, particularly when the tail of the arrow reaches the level of the arrow rest.

Ces dispositifs connus se composent (voir par exemple le brevet américain N° 4 344 409) d'une masse pesante, qui coulisse à l'encontre d'un ressort et d'un repose-flèche monté pivotant également à l'encontre d'un ressort. La masse pesante, sensible aux forces de réaction produites par l'arc lors du lancement de la flèche, constitue un verrou pour maintenir le repose-flèche en position active et, au contraire, pour libérer ce repose-flèche lors du lancement de la flèche, afin de l'escamoter sous l'action de son ressort.These known devices consist (see, for example, US Pat. No. 4,344,409) of a heavy mass, which slides against a spring and an arrow rest mounted also pivoting against a spring. The heavy mass, sensitive to the reaction forces produced by the bow when the arrow is launched, constitutes a lock to keep the arrow rest in the active position and, on the contrary, to release this arrow rest when the arrow is launched , in order to retract it under the action of its spring.

On comprend, bien entendu, que la libération du repose-flèche doit être extrêmement rapide puisqu'elle doit s'effectuer en un temps inférieur au temps de passage de la flèche devant l'âme de l'arc. Or, il est apparu que le dispositif connu ci-dessus ne permet pas d'aboutir, de manière fiable, à ce résultat. En outre, il manque totalement de sensibilité et est le siège de vibrations qui entraînent le repose-flèche en oscillations lors du lancement de la flèche.It is understood, of course, that the release of the arrow rest must be extremely rapid since it must be carried out in a time less than the time of passage of the arrow in front of the core of the bow. However, it appeared that the device known above does not allow this result to be obtained in a reliable manner. In addition, it totally lacks sensitivity and is the seat of vibrations which cause the arrow rest in oscillations when the arrow is launched.

La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet un dispositif de support de flèche escamotable, caractérisé en ce que le support de flèche est constitué par une tige coulissant sous l'action de son ressort.The present invention aims in particular to remedy these drawbacks and for this purpose relates to a retractable boom support device, characterized in that the boom support consists of a rod sliding under the action of its spring.

Suivant une autre caractéristique de l'invention, la tige coulissante et l'axe de pivotement de la masse pesante sont disposés sensiblement dans un même plan.According to another characteristic of the invention, the sliding rod and the pivot axis of the heavy mass are arranged substantially in the same plane.

Suivant une autre caractéristique de l'invention, la tige coulissante constitue un repose-flèche et est disposée légèrement en oblique par rapport au plan de visée de l'arc.According to another characteristic of the invention, the sliding rod constitutes an arrow rest and is disposed slightly obliquely relative to the plane of sight of the arc.

Suivant une autre caractéristique de l'invention, la masse pesante est pourvue d'une ouverture qui la traverse de part en part et qui est traversée avec jeu par la tige coulissante, la tige étant pourvue d'une saillie latérale venant en appui, sous l'action de son ressort contre le bord de l'ouverture, la largeur de la tige à hauteur de la saillie étant inférieure à celle de l'ouverture.According to another characteristic of the invention, the heavy mass is provided with an opening which passes right through it and which is crossed with play by the sliding rod, the rod being provided with a lateral projection coming to bear, under the action of its spring against the edge of the opening, the width of the rod at the height of the projection being less than that of the opening.

La présente invention a en conséquence pour but la réalisation d'un dispositif de support de flèche escamotable, qui soit robuste, rapide et précis, ce dispositif n'étant pas, en outre, le siège d'oscillations parasites venant perturber son fonctionnement.The present invention therefore aims to achieve a retractable boom support device, which is robust, fast and precise, this device is not, moreover, the seat of parasitic oscillations from disturbing its operation.

Sur la figure 1, on a représenté l'âme 1 d'un arc dont la poignée est située en 11. Cet arc reçoit une flèche 2.In Figure 1, there is shown the core 1 of an arc whose handle is located at 1 1 . This arc receives an arrow 2.

La flèche est positionnée à hauteur de l'âme 1, d'une part par un écarteur de flèche 3, d'autre part par un repose-flèche 4.The arrow is positioned at the height of the core 1, on the one hand by an arrow spacer 3, on the other hand by an arrow rest 4.

Ce repose-flèche 4 se compose d'un boîtier creux 5 de forme générale cylindrique, qui est pourvu d'un prolongement fileté 6 servant à la fixation du boîtier 5 sur l'âme 1 par l'intermédiaire d'un écrou 7, d'un contre-écrou 8 et d'une plaque d'appui 9.This arrow rest 4 consists of a hollow housing 5 of generally cylindrical shape, which is provided with a threaded extension 6 used for fixing the housing 5 to the core 1 by means of a nut 7, d 'a lock nut 8 and a support plate 9.

A l'intérieur du boîtier creux 5 est disposée une masse pesante 10, également de forme générale cylindrique, qui est montée à pivotement sur un axe supérieur 11 du boîtier, cet axe étant disposé dans un plan passant par la t.-ge coulissante. Cette masse pesante 10 est pourvue d'une ouverture 12 de forme générale conique qui la traverse de part en part.Inside the hollow housing 5 is disposed a heavy mass 10, also of generally cylindrical shape, which is pivotally mounted on an upper axis 11 of the housing, this axis being disposed in a plane passing through the sliding t.-ge. This heavy mass 10 is provided with an opening 12 of generally conical shape which passes right through it.

Le boîtier 5 est pourvu, de part et d'autre de la masse pesante 10, de deux orifices 131 et 132 qui reçoivent à coulissement une tige 14. Cette tige 14 constitue le repose-flèche proprement dit et traverse de part en part le boîtier 5 afin que dans l'une de ses positions (représentée sur la figure 1), la flèche 2 puisse venir en appui sur la tige 14. Cette tige 14 est montée à coulissement dans le boîtier 5 sous l'action d'un ressort à boudin 15, qui est disposé dans le prolongement 6 autour de la tige 14. Cette tige 14 est également pourvue d'une saillie 16 réalisée sous la forme d'une collerette annulaire et sur laquelle vient en appui l'une des extrémités du ressort 15. Le diamètre intérieur du ressort 16 est inférieur au diamètre de la collerette. La collerette 16 est d'un diamètre inférieur au diamètre de la petite base de l'ouverture conique 12 et, en position de verrouillage représentée sur la figure 1, l'axe de l'ouverture 12 est décalé de celui de la tige 14, de façon que la collerette 16 vienne en appui contre l'une des faces de la masse pesante 10 à hauteur du bord de l'ouverture 12.The housing 5 is provided, on either side of the heavy mass 10, with two orifices 13 1 and 13 2 which slide a rod 14. This rod 14 constitutes the arrow rest proper and passes right through the housing 5 so that in one of its positions (shown in Figure 1), the arrow 2 can come to bear on the rod 14. This rod 14 is slidably mounted in the housing 5 under the action of a coil spring 15, which is disposed in the extension 6 around the rod 14. This rod 14 is also provided with a projection 16 produced in the form of an annular collar and on which one of the ends of the spring 15. The internal diameter of spring 16 is less than the diameter of the collar. The collar 16 has a diameter less than the diameter of the small base of the conical opening 12 and, in the locking position shown in FIG. 1, the axis of the opening 12 is offset from that of the rod 14, so that the flange 16 comes to bear against one of the faces of the heavy mass 10 up to the edge of the opening 12.

La masse pesante 10 comporte également un perçage 17 (voir figure 2) à l'intérieur duquel est monté un ressort à boudin 18 repoussant un doigt 19. Ce doigt vient par ailleurs en appui contre la paroi interne du boîtier creux 5. Ce ressort, dont l'axe 181 est situé sensiblement parallèlement au plan 20 contenant l'axe de pivotement 11 et la tige coulissante 14, maintient la masse pesante 10 en appui latéral contre la paroi interne du boîtier creux 5The weight 10 also includes a bore 17 (see FIG. 2) inside which is mounted a coil spring 18 pushing a finger 19. This finger also comes to bear against the internal wall of the hollow housing 5. This spring, whose axis 18 1 is located substantially parallel to the plane 20 containing the pivot axis 11 and the sliding rod 14, keeps the heavy mass 10 in lateral support against the internal wall of the hollow housing 5

Lors du lancer de la flèche 2, les forces de réaction créées sur l'âme de l'arc par la corde de cet arc produisent le pivotement de la masse pesante 10 autour de l'axe 11 à l'encontre du ressort 18. Cela a pour effet de placer l'ouverture conique 11 en concordance de la collerette 16 de façon que le ressort 15 repousse brusquement la tige 14 jusqu'à ce que cette saillie 16 vienne en appui dans un logement opposé 51 du boîtier 5. Dans cette position, la tige 14 est complètement escamotée à l'intérieur du prolongement 6 et la flèche peut poursuivre sa trajectoire sans risque d'être déviée par la mise en contact de son empennage avec cette tige 14.When throwing the arrow 2, the reaction forces created on the core of the arc by the string of this arc produce the pivoting of the heavy mass 10 around the axis 11 against the spring 18. This has the effect of placing the conical opening 11 in accordance with the flange 16 so that the spring 15 abruptly pushes the rod 14 until this projection 16 comes to bear in an opposite housing 5 1 of the housing 5. In this position, the rod 14 is completely retracted inside the extension 6 and the boom can continue its trajectory without risk of being deflected by bringing its tail into contact with this rod 14.

Pour produire le réarmement de ce repose-flèche, il suffit d'exercer une poussée sur l'extrémité 141, ce qui a pour effet de faire pivoter la masse pesante 10 à l'encontre du ressort 18, du fait du glissement de la saillie 16 contre la paroi conique de l'ouverture 12. Ce mouvement se poursuit jusqu'à ce que la saillie 16 se place au-delà de la masse pesante 10. A ce moment, le ressort 18 ramène la masse pesante 10 dans la position représentée sur la figure 2 et on peut alors relâcher la pression exercée sur la tige 14 de façon que la collerette 16 vient à nouveau en appui sur la face latérale de la masse pesante 10. Comme on le remarque sur la figure 1, le boîtier 5 est fixé par son prolongement 6 sur l'âme 1 de l'arc, de façon que la tige coulissante 14 soit légèrement inclinée par rapport au plan de visée 21. Cette disposition a pour effet d'améliorer le maintien de la flèche sur la tige coulissante 14 en tendant à la faire glisser vers l'écarteur 3 afin d'éviter qu'elle ne tombe de la tige coulissante.To produce the reset of this arrow rest, it suffices to exert a push on the end 14 1 , which has the effect of making the heavy mass 10 pivot against the spring 18, due to the sliding of the projection 16 against the conical wall of the opening 12. This movement continues until the projection 16 is placed beyond the heavy mass 10. At this time, the spring 18 brings the heavy mass 10 back into the position shown in Figure 2 and we can then release the pressure on the rod 14 so that the flange 16 again comes to bear on the side face of the heavy mass 10. As can be seen in Figure 1, the housing 5 is fixed by its extension 6 to the core 1 of the arc, so that the sliding rod 14 is slightly inclined relative to the sight plane 21. This arrangement has the effect of improving the retention of the arrow on the rod sliding 14 while tending to slide it towards the spacer 3 in order to prevent it from falling e the sliding rod.

Sur la figure 3, on a représenté un support de flèche réalisé également sur le même principe de construction mais qui constitue, dans ce cas, un écarteur de flèche dénommé également "berger bouton".In Figure 3, there is shown an arrow support also produced on the same principle of construction but which constitutes, in this case, an arrow spacer also called "button shepherd".

Dans ce cas, le boîtier cylindrique 22 est pourvu d'un prolongement 23 par lequel il est fixé, à l'âme 1 de l'arc, par l'intermédiaire d'une bague filetée 24 et d'une pièce de blocage 25 à vis pointeau 26. Le boîtier 22 comporte un axe de pivotement 27 pour une masse pivotante 28. Cette masse est pourvue d'une ouverture 29 qui est traversée par une tige 30 montée à coulissement de part et d'autre de la masse pesante 28 dans des orifices 221 et 222 du boîtier.In this case, the cylindrical housing 22 is provided with an extension 23 by which it is fixed, to the core 1 of the arc, by means of a threaded ring 24 and a locking piece 25 to needle screw 26. The housing 22 has a pivot axis 27 for a pivoting mass 28. This mass is provided with an opening 29 which is traversed by a rod 30 slidably mounted on either side of the heavy mass 28 in orifices 22 1 and 22 2 of the housing.

La tige 30 est réalisée en deux parties 31 et 32, coulissant coaxialement l'une dans l'autre, à l'encontre d'un ressort d'amortissement 33 qui tend constamment à maintenir l'extrémité 321 de la partie interne 32 contre une saillie interne de la partie externe 33.The rod 30 is made in two parts 31 and 32, sliding coaxially one inside the other, against a damping spring 33 which constantly tends to hold the end 32 1 of the internal part 32 against an internal projection of the external part 33.

La force de compression de ce ressort 33 peut être réglée par une première vis 34 bloquée par une seconde vis 35.The compression force of this spring 33 can be adjusted by a first screw 34 blocked by a second screw 35.

La partie 32 de la tige est pourvue à son extrémité libre d'une pièce 322 sur l'extrémité de laquelle vient s'appuyer la flèche 2, pour la maintenir écartée de l'âme de l'arc 1.The part 32 of the rod is provided at its free end with a part 32 2 on the end of which the arrow 2 comes to bear, in order to keep it apart from the core of the arc 1.

La partie 31 de la tige coulissante 30 est pourvue d'une collerette circulaire extérieure 36 dont le diamètre est légèrement inférieur à celle de l'ou verture tronconique 29 de la masse pesante 28.The part 31 of the sliding rod 30 is provided with an external circular flange 36 whose diameter is slightly less than that of the frustoconical opening 29 of the heavy mass 28.

Cette collerette 36 sert par ailleurs d'appui à un ressort à boudin 37 disposé coaxialement à l'extérieur de la partie 31, afin que ce ressort 37 tende constamment à maintenir la saillie 36 contre le bord de l'ouverture tronconique 29.This flange 36 also serves as a support for a coil spring 37 disposed coaxially outside the part 31, so that this spring 37 constantly tends to hold the projection 36 against the edge of the frustoconical opening 29.

Le fonctionnement de ce dispositif est le suivant.The operation of this device is as follows.

Lors d'un lancer de flèche, l'accélération brutale qu'elle subit se traduit par un léger cintrement de la hampe de la flèche qui pourrait se traduire par une déviation de sa trajectoire. Cette déviation est cependant évitée par l'écarteur de flèche conforme à l'invention, du fait que la partie 32 de la tige 30 coulisse à l'encontre du ressort d'amortissement 33 afin de prendre en considération le cintrage du support de flèche et en évitant de dévier sa trajectoire. Simultanément à cet amortissement, les forces de réaction créées lors du lâcher de la corde se traduisent par un pivotement de la masse pesante 28 jusqu'à ce que la collerette 36 échappe au rebord de la masse pesante 28. Le ressort 37 repousse alors brusquement l'ensemble de la tige 30 en escamotant l'extrémité 322 à l'intérieur du prolongement 23.During an arrow throw, the sudden acceleration it undergoes results in a slight bending of the shaft of the arrow which could result in a deviation from its trajectory. This deviation is however avoided by the deflector of boom according to the invention, because the part 32 of the rod 30 slides against the damping spring 33 in order to take into account the bending of the boom support and avoiding to deviate from its trajectory. Simultaneously with this damping, the reaction forces created when the rope is released result in a pivoting of the heavy mass 28 until the flange 36 escapes the edge of the heavy mass 28. The spring 37 then suddenly repels the 'assembly of the rod 30 by retracting the end 32 2 inside the extension 23.

La remise en position active de l'écarteur de flèche s'effectue de la même manière que pour le repose-flèche en repoussant la tige 30 à l'encontre du ressort 37 jusqu'à ce que la collerette 36 vienne en appui contre le bord de l'ouverture 29 de la masse pesante 28.The return to active position of the boom spreader is carried out in the same way as for the arrow rest by pushing the rod 30 against the spring 37 until the flange 36 comes to bear against the edge of the opening 29 of the weight 28.

Dans l'exemple de réalisation de la figure 4, on a représenté un dispositif de support de flèche comportant, en combinaison, le repose-flèche 4 et l'écarteur de flèche 3. Dans ce cas, le boîtier 40 contient deux masses pesantes 41 et 42 pivotant sur un même axe 43 et qui constituent, l'une 41 le verrou de la tige coulissante 14 du repose-flèche 4, l'autre 42 le moyen de verrouillage pour la tige coulissante 30 de l'écarteur de flèche 3.In the embodiment of Figure 4, there is shown an arrow support device comprising, in combination, the arrow rest 4 and the arrow spacer 3. In this case, the housing 40 contains two heavy masses 41 and 42 pivoting on the same axis 43 and which constitute, one 41 the lock of the sliding rod 14 of the arrow rest 4, the other 42 the locking means for the sliding rod 30 of the arrow spreader 3.

La masse pesante 41 est pourvue d'une ouverture conique 12 dont le bord forme la butée de verrouillage de la collerette 16 Cette masse pesante 41 comporte également une seconde ouverture 44 qui forme un passage pour la partie extérieure 31 de la tige coulissante 30. Cette ouverture 44 est de dimensions suffisantes pour que la masse pesante 41 ne vienne jamais en contact de cette partie 31, quelle que soit sa position angulaire. Par contre, la masse pesante 42 comporte une ouverture 45 contre le bord de laquelle vient s'appliquer la collerette 36 lorsque l'écarteur de flèche 3 est en position active. Cette ouverture 45 se prolonge jusqu'à la périphérie de la masse pesante 42 afin de permettre également le passage de la tige coulissante 14 sans cependant intervenir sur le débattement de cette tige.The heavy mass 41 is provided with a conical opening 12 whose edge forms the locking stop of the flange 16 This heavy mass 41 also has a second opening 44 which forms a passage for the external part 31 of the sliding rod 30. This opening 44 is of sufficient dimensions so that the heavy mass 41 never comes into contact with this part 31, whatever its angular position. On the other hand, the heavy mass 42 has an opening 45 against the edge of which the flange 36 is applied when the deflector 3 is in the active position. This opening 45 extends to the periphery of the heavy mass 42 so as to also allow the passage of the sliding rod 14 without, however, affecting the movement of this rod.

Des joints toriques en matériau autolubrifiant 46, pourront être prévus autour des tiges coulissantes 30 et 14 afin de parfaire leur guidage.O-rings made of self-lubricating material 46 may be provided around the sliding rods 30 and 14 in order to perfect their guidance.

Egalement, le guidage latéral des masses pesantes 10, 28, 41 et 42 pourra être amélioré en prévoyant des billes de roulement 47 (voir figures 1 et 3).Also, the lateral guidance of the heavy masses 10, 28, 41 and 42 could be improved by providing rolling balls 47 (see Figures 1 and 3).

Dans tous ces modes de réalisation, la force des ressorts sera de préférence réglable afin de l'adapter à la force de réaction produite, cette force de réaction étant elle-même fonction de la puissance de l'arc.In all of these embodiments, the force of the springs will preferably be adjustable in order to adapt it to the reaction force produced, this reaction force being itself a function of the power of the arc.

Egalement, suivant les modes de réalisation des figures de 1 à 6, la masse pesante est montée pivotante. Par contre, suivant le mode de réalisation des figures de 7 à 9, la masse pesante est montée pivotante suivant un axe perpendiculaire à la tige coulissante. Ainsi, dans ce cas, la masse pesante 50 est réalisée sous la forme d'un cylindre à section circulaire et est pourvue d'un orifice axial servant de passage à la tige coulissante 52 dont l'extrémité 53 forme le repose-flèche. La masse pesante 50 est montée pivotante au voisinage de l'une de ses extrémités sur des portions d'axe 57 formées à l'extrémité de vis 56 vissées dans la paroi du boîtier 54 de façon que ces portions d'axe 57 soient orientées perpendiculairement à la tige 52. L'orifice axial 51 est pourvu d'une extrémité de section rétrécie 511 contre laquelle est appliqué un joint torique 58. Cette partie rétrécie 511 est destinée à constituer une butée pour la saillie latérale 59 de la tige coulissante 52 sur laquelle agit le ressort hélicoïdal 60.Also, according to the embodiments of Figures 1 to 6, the weight is pivotally mounted. By cons, according to the embodiment of Figures 7 to 9, the weight is pivotally mounted along an axis perpendicular to the sliding rod. Thus, in this case, the heavy mass 50 is produced in the form of a cylinder with circular section and is provided with an axial orifice serving as a passage for the sliding rod 52 whose end 53 forms the arrow rest. The weight 50 is pivotally mounted in the vicinity of one of its ends on axis portions 57 formed at the end of screws 56 screwed into the wall of the housing 54 so that these axis portions 57 are oriented perpendicularly to the rod 52. The axial orifice 51 is provided with a narrowed section end 51 1 against which an O-ring 58 is applied. This narrowed part 51 1 is intended to constitute a stop for the lateral projection 59 of the sliding rod 52 on which the helical spring 60 acts.

Le boîtier 54 est fermé par un couvercle 61 contre lequel vient s'appliquer l'une des extrémités d'un ressort 62 logé dans une perforation de l'extrémité de la masse pesante 50.The housing 54 is closed by a cover 61 against which one of the ends of a spring 62 is applied, housed in a perforation in the end of the heavy mass 50.

Le fonctionnement de ce dispositif est similaire à celui du mode de réalisation des figures de 1 à 6. Ainsi, lors de la libération de la corde de l'arc, les forces de réaction créées produisent le pivotement de la masse 50 autour des portions d'axe 57 jusqu'à ce que l'orifice 51 se place coaxialement à la saillie 59. A ce moment, le ressort 60 fait coulisser brusquement la tige 52 pour que son extrémité de repose-flèche 53 s'escamote à l'intérieur du prolongement fileté 55 du boîtier 54.The operation of this device is similar to that of the embodiment of Figures 1 to 6. Thus, upon release of the string from the bow, the reaction forces created produce the pivoting of the mass 50 around the portions d axis 57 until the orifice 51 is placed coaxially with the projection 59. At this time, the spring 60 causes the rod 52 to slide suddenly so that its end of the arrow rest 53 retracts inside the threaded extension 55 of housing 54.

Le réarmement du repose-flèche s'effectue par la manoeuvre inverse en appuyant sur l'extrémité arrière de la tige coulissante 52 à l'encontre du ressort 60.Resetting of the arrow rest is effected by the reverse operation by pressing the rear end of the sliding rod 52 against the spring 60.
