- a rifle stock comprises several gripping and support zones in contact with the shooter.
- a rifle stock comprises a heel towards its rear end, intended to come into contact substantially at the level of the shooter's shoulder and chest. It further comprises a comb in the upper support part, intended to come to rest against the cheek of the shooter. It also comprises at least one zone, called a handle, for its grip by the shooter.
- a general object of the invention of the invention consists in proposing a solution making it possible to optimize the function of a rifle stock which improves the solutions of the state of the art, does not present all or part of the support of disadvantages of the state of the art.
- the invention seeks to improve the behavior of a rifle stock, its better adaptation to the morphology of the shooter.
- the invention is based on a rifle stock comprising a stock body, a heel and a comb mounted on the stock body, characterized in that it comprises at least a first adjustment element comprising on the one hand a device for direct or indirect connection with a rifle barrel, and on the other hand a first cam surface in direct or indirect connection with the body of the butt, this first cam surface allowing adjustment of at least an orientation of the stock body relative to said first adjustment element, and in that it comprises a first blocking and fixing device making it possible to fix the stock body relative to said first adjustment element in a chosen position.
- the first cam surface of the first adjustment element advantageously allows adjustment of the at least one orientation of the stock body continuously according to an infinity of positions over a predefined range.
- the stock body or a second intermediate adjuster may include an adjuster surface shaped to match the first cam surface of the first adjuster, allowing adjustment by displacement of this adjustment surface in contact with the first cam surface.
- the first cam surface can be substantially in the form of a cylinder portion arranged around a first axis, allowing orientation adjustment according to a displacement of the rotation type around said first axis of the first cam surface.
- the rifle stock may comprise at least a second adjustment element connected to said first adjustment element, comprising an adjustment surface cooperating with said first cam surface for its adjustable positioning relative to said first adjustment element, and comprising a second cam surface in connection, directly or indirectly, with the stock body, according to an infinity of positions of the stock body relative to said second adjustment element, this second cam surface thus allowing a second adjustment of the orientation of the stock body relative to said first adjustment element, and comprising a second blocking and fixing device making it possible to fix the stock body relative to said second adjustment element in a chosen position.
- the rifle stock may include one or more camming surfaces, arranged around a transverse axis and/or arranged around a vertical axis and/or arranged around a longitudinal axis, for one or more stock body.
- first and/or the second cam surface can be in the form of walls of a hollow portion comprising at least two elastically movable parts with respect to each other, of which respectively a first part comprises at least one through opening and a second part at least one aligned threaded opening, and the fastening and blocking device may comprise a screw passing through the through opening of the first part and the end of which is screwed into the tapped opening of the second part so as to bring said two parts together by screwing and form a fixing or not of the adjustment surface engaged in respectively the first and/or second cam surface.

- the heel can comprise at least two separate support elements, including an upper support element intended to come to rest against the shoulder of a shooter and a lower support element intended to come to rest against the chest of the shooter.
- a shooter mounted on the same base, at least one of the support elements being movable relative to the base for adjusting its position, in particular movable according to two, three or four degrees of freedom and/or the heel can comprise at least two separate support elements whose position is adjustable according to two, three, four, five or six degrees of freedom relative to the butt body of the rifle butt.
- the comb can be mounted adjustable relative to the stock body, in particular in an inclinable manner relative to a longitudinal axis.
- the invention also relates to a gun, characterized in that it comprises a gun stock as described previously.
- the rifle may include a grip including a longitudinal through opening, the rear surface of the grip being positioned in contact with the front surface of the first adjustment element of the rifle stock, a screw passing through said handle to engage with a rifle barrel positioned against the front surface of the handle, so as to fix the first adjustment element the rifle butt, the grip and the rifle barrel between them.
- Longitudinal direction means the direction parallel to the longitudinal axis of the rifle on which is mounted or intended to be mounted the rifle butt, i.e. along the longitudinal axis of the rifle barrel.
- the longitudinal axis of the rifle stock and the rifle barrel are aligned. Due to the invention, as will be detailed later, a gun can assume configurations in which these longitudinal axes will no longer be aligned: we can then consider as the longitudinal direction that of the gun stock when it is considered relatively in its nominal configuration or detached from a barrel.
- vertical direction is meant the direction perpendicular to the longitudinal direction and perpendicular to the ground. It forms with the longitudinal axis of a rifle or of the butt of a rifle a vertical median plane of the rifle, when the rifle is positioned in its nominal configuration. Such a median plane is generally a plane of symmetry or substantially of symmetry of a gun.
- transverse direction is meant the perpendicular to the vertical and longitudinal directions. It is also perpendicular to the aforementioned vertical median plane.
- horizontal direction will be used for any direction in a plane perpendicular to the vertical direction. The longitudinal and transverse directions thus define a horizontal plane.
- the invention is based on a rifle stock comprising at least one element for adjusting its position relative to a rifle barrel to which it is linked, and/or relative to a handle to which it is linked.
- This or these adjustment elements form a device for adjusting the position of the rifle stock.
- this adjustment is based over at least two degrees of freedom in rotation, or more generally two degrees of freedom in orientation, as will be detailed later.
- this adjustment allows continuous orientation adjustment, according to an infinity of possible orientations between two predefined limits of a predefined angular range.
- the figures 1 and 2 thus represent a part of a rifle stock comprising two adjustment elements according to one embodiment, and the figures 3 to 14 more precisely illustrate some of the main elements of such a rifle stock.
- the figures 1 and 2 illustrate a rifle stock part comprising a stock body 1 and a device for adjusting its position making it possible to fix this stock body to a gun barrel and/or to a handle by allowing its position to be adjusted, in particular of its orientation, relative to such a gun barrel and/or such a handle.
- This adjustment device comprises a first adjustment element 10 and a second adjustment element 20, which will now be described in detail.
- the first adjustment element 10 is intended for direct attachment to the barrel of the rifle, and/or to a handle of the rifle stock which is positioned between this first adjustment element 10 and the barrel of the rifle.
- the second adjustment element 20 is directly fixed to the first adjustment element 10 on the one hand and to the stock body 1 on the other hand. It therefore forms an intermediate element.
- the second adjustment element 20 and the first adjustment element 10 are fixed together by an adjustable connection, allowing adjustment of their respective orientation relative to a transverse axis.
- the stock body 1 is likewise fixed to the second adjustment element 20 by an adjustable connection, allowing adjustment of their respective orientation relative to a vertical axis.
- This construction thus finally allows a double orientation of a stock body 1 relative to a gun barrel, and/or to a handle, and therefore allows adjustment of the position of a stock body 1 on a gun barrel according to two degrees of freedom, relative to two mutually perpendicular axes according to the embodiment.
- the adjustment device could be limited to a single adjustment element.
- the adjustment could be limited to an adjustment according to a single degree of freedom, and/or according to a single orientation among the two orientations shown.
- the adjustment device could comprise more than two degrees of freedom and/or more than two adjustment elements.
- the figures 3 to 7 represent the first adjustment element 10 of the adjustment device.
- This first adjustment element 10 comprises a front face 11, particularly visible on the figure 4 , intended for fixing a handle and a gun barrel, not shown.
- a connecting device any mechanical connecting device can be considered.
- the front face 11 comprises openings 12 which allow the positioning of a handle, the latter comprising a longitudinal opening allowing the passage of a screw, in particular a tie-rod screw whose head is housed in a opening 12 and the end comes into engagement with the barrel of the rifle, thus allowing the clamping and fixing of the assembly around the handle of the rifle.
- the first adjustment element 10 comprises on the face substantially opposite the front face 11 a connection device with a stock body 1.
- this connection with the stock body 1 is indirect, since it is done via a second adjustment element 20, mentioned above. Alternatively, it could be direct.
- This connecting device comprises a hollow portion 13 of substantially open cylindrical shape, delimited by a wall which forms a cam surface 16. It extends around a first transverse axis 14, over the entire width of the first adjustment element. This hollow portion 13 opens towards the rear through an opening 15, which also extends over the entire width of the first adjustment element.
- the hollow connection portion 13 is delimited by a wall, forming a cam surface 16 in the form of a cylinder portion, the section of which by a vertical longitudinal plane is substantially circular, truncated over a circular sector of approximately 90 degrees, which corresponds at the opening 15 mentioned above. This section is constant over the entire width of the first adjustment element 10, two of these sections being visible respectively on the figures 6 and 7 .
- the opening 15 defines the cam surface 16 in two parts 161, 162 facing each other. These two parts 161, 162 are further separated by a thin hollow portion 163, substantially planar, extending over the entire width of the first adjustment element 10. This hollow portion 163 makes it possible to provide elastic mobility relative to the two parts 161 , 162, whose function will be specified later.
- the underside 17 of the first adjustment element 10 further comprises several openings.
- Two openings 171 pass through, through the first part 161 of the wall forming the cam surface 16, symmetrically distributed around a vertical longitudinal median plane. These openings 171 are aligned with threaded openings 172 arranged in the second part 162 of the cam surface 16, as is particularly visible on the section of the figure 6 .
- Two other through openings 173 are also arranged through the first part 161 of the cam surface 16. They are aligned in a substantially longitudinal direction, positioned at the level of the vertical longitudinal median plane of the first adjustment element 10.
- the figures 8 to 11 represent the second adjustment element 20 of the rifle stock, arranged intermediately between the first adjustment element 10 and the stock body 1.
- This second adjustment element 20 comprises a first portion in relief 23, of shape corresponding to the hollow connecting portion 13.
- This portion in relief 23 is intended for insertion with play into the hollow connecting portion 13 of the first element 10, so as to fix the two elements together.
- the portion in relief 23 is delimited by an adjustment surface 27 and represents the male part and the hollow connection portion 13 the female part of a mechanical connection between the two adjustment elements 10, 20.
- the cam surface 16 of the first adjustment element 10 cooperates with the adjustment surface 27 of the second adjustment element 20.
- the two respective surfaces 16, 27 of the two adjustment elements 10, 20 can move the relative to the other, in contact, by friction with play.
- the cam surface 16 of the hollow portion 13 thus guides the movement of the raised portion 23.
- the two surfaces 16, 27 in contact being of cylindrical shape, the second adjustment element 20 is rotatable relative to the first transverse axis 14 of the first adjustment element 10.
- the stock body 1, connected to the second adjustment element 20 can be adjusted rela tively to the gun barrel and/or to the handle by this mobility around this first transverse axis 14, which makes it possible to position it more or less high in the vertical direction, more precisely to raise or lower its rear part.
- the adjustment surface 27 is inscribed in a cylinder with a transverse axis. According to the embodiment, it is discontinuous, formed by several parallel discs delimiting spaces 22. These spaces 22 make it possible to lighten the second adjustment element 20, while allowing the passage of locking and fixing screws, as will be detailed afterwards.
- the second adjustment element 20 further comprises a hollow portion, arranged on its face opposite the portion in relief 23, forming a hollow connection portion delimited by a second cam surface 26, similar to the hollow connection portion 13 of the first element, of substantially cylindrical shape, but arranged around a vertical axis 24.
- This second cam surface 26 also comprises at least two parts 261 and 262, elastically movable with respect to each other via cutouts 263, as is particularly visible on the figure 11 .
- the wall part 262 comprises through openings 271, aligned with threaded openings 272 of the other wall part 261.
- the raised portion 23 is connected to the rest of the second adjustment element 20 by a narrow part or neck 25, intended to position itself at the level of the opening 15 of the hollow portion 13 of the first adjustment element 10.
- the figures 12 to 14 finally illustrate the stock body 1 according to the embodiment of the invention.
- This butt body 1 represents the main central part of a rifle butt. It is intended for attachment to a gun barrel, via a connecting portion in relief 3 forming a substantially cylindrical adjustment surface 7, arranged at its front face 2, similar to the portion in relief 23 of the second adjustment element 20. It further comprises a connecting device with a comb, not shown, in its upper part 4, and a connecting part 5 with a heel at its rear face 6, as will be described by the sequel in relation to figures 15 to 22 .
- the stock according to the embodiment comprises a device for blocking and fixing the various elements together. Indeed, when an orientation between two elements of the butt is considered suitable, it is then necessary to block the chosen orientation and to fix the two elements reliably in this orientation. This fixing is chosen so as to withstand the repeated efforts undergone by a gun during firing.
- the blocking and fixing device according to the embodiment is based on screws, one embodiment of which will be specified below.
- the second adjustment element 20 is first arranged in cooperation with the first adjustment element 10, by inserting its male part inside the corresponding female part by translation in the transverse direction, the neck 25 of the second adjustment element 20 is positioned in the opening 15 of the first adjustment element 10. The user then proceeds to the adjustment by relative movement of the two adjustment elements, their respective surfaces 16, 27 sliding in contact against one another. When the orientation is considered suitable, the relative position of the two adjustment elements 10, 20 is locked and the two adjustment elements 10, 20 are fixed together.
- This blocking and fixing can be done in several stages. For example, two screws, not shown, can first be inserted respectively into each opening 171 and then tightened in the threaded openings 172: this tightening brings together the two parts 161, 162 of the cam surface 16 which clamp the portion in relief 23 housed in the hollow portion 13, to prevent its mobility. She is then caught in a vice. The tightening is distributed over the entire contact surface of the two surfaces 16, 27, which makes it very effective.
- two other screws 71 are then added in a second time in the openings 173, and screwed until a complementary blocking of the portion in relief 23, by means of nuts 73, by coming into direct support on the adjustment surface 26.
- the two adjustment elements 10, 20 are fixed to each other in an integral manner, with a fixing device which supports the forces undergone by the shots of the rifle without becoming loose.
- the invention is not limited to the blocking and fixing device described.
- the latter could take other configurations, such as for example another type of screwing, another number of screws, and/or any other fixing device than a screwing.
- the adjustment range can be limited by stops. It advantageously extends over a large range, for example extends from a first angle of orientation comprised between -40 degrees to +40 degrees, or even between -20 and +20 degrees, choosing by convention zero orientation in the nominal configuration, that is to say when the butt body is aligned with the gun barrel. According to this first orientation around a transverse axis, the first angle of orientation is measured in a vertical longitudinal plane, relative to a horizontal direction. This orientation moves the stock body upwards or downwards, its rear part undergoing the maximum amplitude of displacement relative to an initial horizontal plane.
- fixing is possible for any angle of orientation included in the range provided. Indeed, the adjustment is carried out by a continuous relative displacement of an adjustment surface on a cam surface. The adjustment thus makes it possible to be carried out from an infinity of positions, any orientation value being able to be chosen within the predefined range.
- the orientation can be modified by loosening the fixing screws until reaching the relative mobility of the two elements allowing the orientation adjustment explained above.
- connection portion in relief 3 of the stock body 1 is housed in the corresponding hollow connection portion, so that the adjustment surface 7 delimiting the connection portion in relief 3 comes into contact with the second cam surface 26, allowing the relative displacement of two components.
- a blocking and fixing device is actuated to secure the two components in this chosen orientation.
- the blocking device rests on four screws, including two fixing screws which pass respectively through the openings 271, 272 of the second adjustment element, so as to achieve tightening of the connection portion in relief 3 of the stock body by bringing together the two opposite walls 261, 262.
- two other screws 71 are added to bear against the adjustment surface of the connection portion in relief 3 and complete the fixing.
- the setting range can be the same as mentioned for the first setting.
- this adjustment is likewise advantageously continuous over the entire predefined range, offering an infinity of possible orientations.
- the orientation adjustment can therefore be very fine.
- This second orientation adjustment is carried out along a vertical axis, which induces a left-right adjustment of the stock body, of maximum amplitude for its rear part.
- the cam surface could have a shape other than a cylinder portion, to cause a movement combining a change of orientation and a translation for example.
- the cam surface could also have a shape combining more than one orientation. It could be of the ball joint type, allowing orientation adjustment in all directions.
- a simplified embodiment could only include a single adjustment element, and then allow a single adjustment orientation.
- a single adjustment element could allow two degrees of freedom, either by a single cam surface, or by two distinct cam surfaces, and for example implement the two orientations described above.
- an additional adjustment, or replacing another adjustment described above could be obtained by orienting the stock body around a longitudinal axis, thus allowing the same inclination of the entire stock body around a longitudinal axis.
- the stock body could be adjustable by one, two or three translations, in addition to the orientations described above.
- the rifle stock according to the embodiment therefore comprises a stock body 1, on which are arranged in the front part a handle and two adjustment elements 10, 20 intermediate.
- the stock body further comprises a comb in the upper part, and a butt in the lower part.
- a connection with a comb can be chosen so that the comb is orientable according to an inclination around a longitudinal axis, as described by the document DE9411466 .
- the stock body 1 further comprises a longitudinal groove 8 in its upper part, which allows adjustment in longitudinal translation, front-rear, of the comb.
- the stock body 1 further comprises an opening in its upper part 4, allowing the housing of a plate for mounting a comb.
- this plate allows adjustment of the position of the comb according to other degrees of freedom than those described above, among a rotation around a vertical axis, around a transverse axis, a vertical translation, a transverse translation .
- a heel is also mounted at the level of the rear face 6 of the butt body 1.
- the rifle heel could be as described by the document WO2020120418 .
- the figures 15 to 22 illustrate a rifle butt 100 intended to be connected to the butt body 1 according to one embodiment.
- the rifle butt according to this embodiment also includes several components, identified by the exploded view of the figure 16 , and represented one by one by the figures 17 to 22 .
- a first component 30 of the rifle butt is in the form of a tube, intended for connection in the connecting part 5 arranged at the rear of the stick body 1.
- This tube can be moved in longitudinal translation relative to the stick body 1 to fix it according to several more or less advanced positions, which thus allows fore-aft adjustment of the heel relative to the stock body 1.
- a second component 40 is illustrated in the figure 18 . It comprises on the one hand a first connection portion 41 with the first component 30, and on the other hand a second connection portion 42, in the form of a slot, for an adjustable connection with a third component 50.
- the third component 50 is illustrated in the figure 19 . It comprises a first connection portion 51 with the second component, allowing position adjustment by rotation about a transverse axis between the two components 40, 50. It comprises a second connection portion 52 for connection with a fourth component 60 .

- the fifth component 70 is illustrated in the figure 21 . It comprises a first connection portion 74 with the fourth component 60. It comprises a second connection portion 75 for a connection adjustable in rotation about a transverse axis with a sixth component 80. More precisely, the second connection portion 75 comprises two identical parts positioned respectively at the two ends of the fifth component 70, which forms an elongated base intended for positioning substantially in the vertical direction.
- the sixth component 80 is illustrated in the figure 22 . It comprises a first connecting portion 81 with the fifth component 70. It comprises a second connecting portion 82, in the form of two parallel grooves substantially oriented in a transverse direction, provided for positioning a support element, not shown , intended to bear directly on the shooter's body. More precisely, the heel comprises two sixth components 80: a first allows the positioning of a first support element at the level of the shooter's shoulder, and a second allows the positioning of a second distinct support element lower , at the level of the shooter's chest. Each sixth component is movable independently relative to the base formed by the fifth component 70, by a rotation around a substantially transverse axis. The two grooves of the second connecting portion 82 allow the additional adjustment of the position of a support element, by a transverse translation and by a rotation around a longitudinal axis.

Description
L'invention concerne une crosse de fusil et un fusil en tant que tel intégrant une telle crosse de fusil.The invention relates to a rifle stock and a rifle as such incorporating such a rifle stock.
Les armes traditionnelles pour le tir de précision, par exemple du type fusil, comprennent une crosse de fusil en bois, formant une structure porteuse à partir de laquelle est solidarisé un canon et le mécanisme de déclenchement du tir. Une telle crosse de fusil comporte plusieurs zones de préhension et d'appui en contact avec le tireur. Notamment, une crosse de fusil comprend un talon vers son extrémité arrière, destiné à venir en contact sensiblement au niveau de l'épaule et de la poitrine du tireur. Elle comprend de plus un busc en partie d'appui haute, destiné à venir en appui contre la joue du tireur. Elle comprend aussi au moins une zone, dite poignée, pour sa prise en main par le tireur.Traditional weapons for precision shooting, for example of the rifle type, comprise a wooden rifle butt, forming a supporting structure from which is secured a barrel and the firing trigger mechanism. Such a rifle stock comprises several gripping and support zones in contact with the shooter. In particular, a rifle stock comprises a heel towards its rear end, intended to come into contact substantially at the level of the shooter's shoulder and chest. It further comprises a comb in the upper support part, intended to come to rest against the cheek of the shooter. It also comprises at least one zone, called a handle, for its grip by the shooter.
La performance et la précision du tir dépendent en grande partie de la position de la crosse de fusil. Particulièrement, il est connu que la précision du tir dépend fortement de la bonne adaptation des appuis de la crosse de fusil à la morphologie du tireur.Shooting performance and accuracy largely depend on the position of the rifle stock. In particular, it is known that the accuracy of the shot strongly depends on the good adaptation of the supports of the rifle butt to the morphology of the shooter.
Lorsqu'un tireur veut optimiser la précision de son fusil, il peut se faire fabriquer une crosse de fusil sur mesure. Une telle crosse de fusil produite sur mesure est naturellement coûteuse et présente l'inconvénient de ne plus pouvoir être modifiée une fois conçue. Ainsi, si la morphologie du tireur change avec le temps, la crosse du fusil devient moins adaptée et le tireur perd en précision.When a shooter wants to optimize the accuracy of their rifle, they can have a custom rifle stock made. Such a custom-produced rifle stock is naturally expensive and has the disadvantage of not being able to be modified once designed. Thus, if the shooter's morphology changes over time, the rifle butt becomes less suitable and the shooter loses precision.
Pour pallier à ces inconvénients, des solutions, comme par exemple celles décrites par les documents
Un objet général de l'invention de l'invention consiste à proposer une solution permettant d'optimiser la fonction d'une crosse de fusil qui améliore les solutions de l'état de la technique, ne présente pas tout ou partie d'appui des inconvénients de l'état de la technique. En particulier, l'invention cherche à améliorer le comportement d'une crosse de fusil, sa meilleure adaptation à la morphologie du tireur.A general object of the invention of the invention consists in proposing a solution making it possible to optimize the function of a rifle stock which improves the solutions of the state of the art, does not present all or part of the support of disadvantages of the state of the art. In particular, the invention seeks to improve the behavior of a rifle stock, its better adaptation to the morphology of the shooter.
A cet effet, l'invention repose sur une crosse de fusil comprenant un corps de crosse, un talon et un busc montés sur le corps de crosse, caractérisée en ce qu'elle comprend au moins un premier élément de réglage comprenant d'une part un dispositif de liaison, directe ou indirecte, avec un canon de fusil, et d'autre part une première surface de came en liaison, directe ou indirecte, avec le corps de crosse, cette première surface de came permettant le réglage d'au moins une orientation du corps de crosse relativement audit premier élément de réglage, et en ce qu'elle comprend un premier dispositif de blocage et fixation permettant de fixer le corps de crosse relativement audit premier élément de réglage dans une position choisie.To this end, the invention is based on a rifle stock comprising a stock body, a heel and a comb mounted on the stock body, characterized in that it comprises at least a first adjustment element comprising on the one hand a device for direct or indirect connection with a rifle barrel, and on the other hand a first cam surface in direct or indirect connection with the body of the butt, this first cam surface allowing adjustment of at least an orientation of the stock body relative to said first adjustment element, and in that it comprises a first blocking and fixing device making it possible to fix the stock body relative to said first adjustment element in a chosen position.
La première surface de came du premier élément de réglage permet avantageusement le réglage de la au moins une orientation du corps de crosse de manière continue selon une infinité de positions sur une plage prédéfinie.The first cam surface of the first adjustment element advantageously allows adjustment of the at least one orientation of the stock body continuously according to an infinity of positions over a predefined range.

Pour simplifier la description qui va suivre, nous utiliserons les définitions précisées ci-dessous.To simplify the description which will follow, we will use the definitions specified below.
Par « direction longitudinale », on entend la direction parallèle à l'axe longitudinal du fusil sur lequel est montée ou destinée à être montée la crosse de fusil, c'est-à-dire selon l'axe longitudinal du canon du fusil. En remarque, dans une configuration nominale d'un fusil, l'axe longitudinal de la crosse de fusil et du canon du fusil sont alignés. Du fait de l'invention, comme cela sera détaillé par la suite, un fusil pourra prendre des configurations dans lesquelles ces axes longitudinaux ne seront plus alignés : nous pourrons alors considérer comme direction longitudinale celle de la crosse de fusil lorsqu'elle sera considérée relativement à sa configuration nominale ou détachée d'un canon."Longitudinal direction" means the direction parallel to the longitudinal axis of the rifle on which is mounted or intended to be mounted the rifle butt, i.e. along the longitudinal axis of the rifle barrel. As a side note, in a nominal configuration of a rifle, the longitudinal axis of the rifle stock and the rifle barrel are aligned. Due to the invention, as will be detailed later, a gun can assume configurations in which these longitudinal axes will no longer be aligned: we can then consider as the longitudinal direction that of the gun stock when it is considered relatively in its nominal configuration or detached from a barrel.
Par « direction verticale », on entend la direction perpendiculaire à la direction longitudinale et perpendiculaire au sol. Elle forme avec l'axe longitudinal d'un fusil ou de la crosse d'un fusil un plan médian vertical du fusil, lorsque le fusil est positionné dans sa configuration nominale. Un tel plan médian est généralement un plan de symétrie ou sensiblement de symétrie d'un fusil.By "vertical direction" is meant the direction perpendicular to the longitudinal direction and perpendicular to the ground. It forms with the longitudinal axis of a rifle or of the butt of a rifle a vertical median plane of the rifle, when the rifle is positioned in its nominal configuration. Such a median plane is generally a plane of symmetry or substantially of symmetry of a gun.
Par « direction transversale », on entend la perpendiculaire aux directions verticale et longitudinale. Elle est aussi perpendiculaire au plan médian vertical susmentionné. On utilisera de plus la mention de « direction horizontale » pour toute direction dans un plan perpendiculaire à la direction verticale. Les directions longitudinale et transversale définissent ainsi un plan horizontal.By "transverse direction" is meant the perpendicular to the vertical and longitudinal directions. It is also perpendicular to the aforementioned vertical median plane. In addition, the term "horizontal direction" will be used for any direction in a plane perpendicular to the vertical direction. The longitudinal and transverse directions thus define a horizontal plane.
Nous utiliserons les adjectifs « avant » et « arrière » relativement au sens d'un fusil, selon la direction longitudinale, l'arrière correspondant au talon en appui sur le corps du tireur.We will use the adjectives "front" and "rear" relative to the direction of a rifle, according to the longitudinal direction, the rear corresponding to the heel resting on the shooter's body.
L'invention repose sur une crosse de fusil comprenant au moins un élément de réglage de sa position relativement à un canon de fusil auquel elle est liée, et/ou relativement à une poignée à laquelle elle est liée. Ce ou ces éléments de réglage forment un dispositif d'ajustement de la position de la crosse de fusil. Avantageusement, cet ajustement repose sur au moins deux degrés de liberté en rotation, ou plus généralement deux degrés de liberté d'orientation, comme cela sera détaillé par la suite. D'autre part, avantageusement, cet ajustement permet un réglage d'orientation continu, selon une infinité d'orientations possibles entre deux bornes prédéfinies d'une plage angulaire prédéfinie.The invention is based on a rifle stock comprising at least one element for adjusting its position relative to a rifle barrel to which it is linked, and/or relative to a handle to which it is linked. This or these adjustment elements form a device for adjusting the position of the rifle stock. Advantageously, this adjustment is based over at least two degrees of freedom in rotation, or more generally two degrees of freedom in orientation, as will be detailed later. On the other hand, advantageously, this adjustment allows continuous orientation adjustment, according to an infinity of possible orientations between two predefined limits of a predefined angular range.

Plus précisément, les
Le premier élément de réglage 10 est destiné à une fixation directe au canon du fusil, et/ou à une poignée de la crosse de fusil qui vient se positionner entre ce premier élément de réglage 10 et le canon du fusil. Le deuxième élément de réglage 20 est directement fixé au premier élément de réglage 10 d'une part et au corps de crosse 1 d'autre part. Il forme donc un élément intermédiaire. Selon le mode de réalisation, le deuxième élément de réglage 20 et le premier élément de réglage 10 sont fixés entre eux par une liaison réglable, permettant un ajustement de leur orientation respective relativement à un axe transversal. Le corps de crosse 1 est de même fixé au deuxième élément de réglage 20 par une liaison réglable, permettant un ajustement de leur orientation respective relativement à un axe vertical. Cette construction permet donc finalement une double orientation d'un corps de crosse 1 relativement à un canon de fusil, et/ou à une poignée, et permet donc le réglage de la position d'un corps de crosse 1 sur un canon de fusil selon deux degrés de libertés, relativement à deux axes perpendiculaires entre eux selon le mode de réalisation.The
L'invention ne se limite naturellement pas à un tel mode de réalisation. De manière simplifiée, le dispositif d'ajustement pourrait se limiter à un seul élément de réglage. L'ajustement pourrait se limiter à un réglage selon un seul degré de liberté, et/ou selon une seule orientation parmi les deux orientations représentées. En variante, le dispositif d'ajustement pourrait comprendre plus de deux degrés de liberté et/ou plus de deux éléments de réglage.The invention is naturally not limited to such an embodiment. In a simplified manner, the adjustment device could be limited to a single adjustment element. The adjustment could be limited to an adjustment according to a single degree of freedom, and/or according to a single orientation among the two orientations shown. Alternatively, the adjustment device could comprise more than two degrees of freedom and/or more than two adjustment elements.
Le dispositif d'ajustement d'une crosse de fusil selon le mode de réalisation va maintenant être décrit de manière plus détaillée, en relation avec les

Ces deux parties 161, 162 sont de plus séparées par une fine portion creuse 163, sensiblement plane, s'étendant sur toute la largeur du premier élément de réglage 10. Cette portion creuse 163 permet d'apporter une mobilité élastique relative aux deux parties 161, 162, dont la fonction sera précisée plus loin.The

La surface de réglage 27 est inscrite dans un cylindre d'axe transversal. Selon le mode de réalisation, elle est discontinue, formée par plusieurs disques parallèles délimitant des espaces 22. Ces espaces 22 permettent d'alléger le deuxième élément de réglage 20, tout en permettant le passage de vis de blocage et fixation, comme cela sera détaillé par la suite.The
Le deuxième élément de réglage 20 comprend de plus une portion creuse, agencée sur sa face opposée à la portion en relief 23, formant une portion creuse de liaison délimitée par une deuxième surface de came 26, similaire à la portion creuse de liaison 13 du premier élément, de forme sensiblement cylindrique, mais agencée autour d'un axe vertical 24. Cette deuxième surface de came 26 comprend aussi au moins deux parties 261 et 262, mobiles élastiquement l'une par rapport à l'autre par l'intermédiaire de découpes 263, comme cela est particulièrement visible sur la
Les
Enfin, la crosse selon le mode de réalisation comprend un dispositif de blocage et de fixation des différents éléments entre eux. En effet, lorsqu'une orientation entre deux éléments de la crosse est considérée convenable, il convient alors de bloquer l'orientation choisie et de fixer les deux éléments de manière fiable dans cette orientation. Cette fixation est choisie de sorte à supporter les efforts répétés subis par un fusil lors de tirs. Le dispositif de blocage et fixation selon le mode de réalisation est basé sur des vis dont un mode de réalisation sera précisé ci-dessous.Finally, the stock according to the embodiment comprises a device for blocking and fixing the various elements together. Indeed, when an orientation between two elements of the butt is considered suitable, it is then necessary to block the chosen orientation and to fix the two elements reliably in this orientation. This fixing is chosen so as to withstand the repeated efforts undergone by a gun during firing. The blocking and fixing device according to the embodiment is based on screws, one embodiment of which will be specified below.
Le fonctionnement de la crosse de fusil selon le mode de réalisation va maintenant être décrit.The operation of the rifle stock according to the embodiment will now be described.
Le deuxième élément de réglage 20 est d'abord agencé en coopération avec le premier élément de réglage 10, en insérant sa partie mâle à l'intérieur de la partie femelle correspondante par translation dans la direction transversale, le col 25 du deuxième élément de réglage 20 se positionnant dans l'ouverture 15 du premier élément de réglage 10. L'utilisateur procède alors au réglage par déplacement relatif des deux éléments de réglage, leurs surfaces 16, 27 respectives coulissant au contact l'une contre l'autre. Lorsque l'orientation est considérée convenable, la position relative des deux éléments de réglage 10, 20 est bloquée et les deux éléments de réglage 10, 20 sont fixés entre eux.The
Ce blocage et fixation peut se faire en plusieurs étapes. Par exemple, deux vis, non représentées, peuvent d'abord être insérées respectivement dans chaque ouverture 171 puis serrées dans les ouvertures taraudées 172 : ce serrage rapproche les deux parties 161, 162 de la surface de came 16 qui viennent serrer la portion en relief 23 logée dans la portion creuse 13, jusqu'à empêcher sa mobilité. Elle est alors prise en étau. Le serrage se répartit sur toute la surface de contact des deux surfaces 16, 27, ce qui le rend très efficace. En complément, deux autres vis 71 sont ensuite ajoutées dans un deuxième temps dans les ouvertures 173, et vissées jusqu'à un blocage complémentaire de la portion en relief 23, par l'intermédiaire d'écrous 73, en venant en appui direct sur la surface de réglage 26. Après serrage des quatre vis mentionnées, les deux éléments de réglage 10, 20 sont fixés l'un à l'autre de manière solidaire, avec un dispositif de fixation qui supporte les efforts subis par les tirs du fusil sans se desserrer.This blocking and fixing can be done in several stages. For example, two screws, not shown, can first be inserted respectively into each
Naturellement, l'invention ne se limite pas au dispositif de blocage et fixation décrit. Ce dernier pourrait prendre d'autres configurations, comme par exemple un autre type de vissage, un autre nombre de vis, et/ou tout autre dispositif de fixation qu'un vissage.Naturally, the invention is not limited to the blocking and fixing device described. The latter could take other configurations, such as for example another type of screwing, another number of screws, and/or any other fixing device than a screwing.
La plage de réglage peut être limitée par des butées. Elle s'étend avantageusement sur une plage importante, par exemple s'étend d'un premier angle d'orientation compris entre -40 degrés à +40 degrés, voire entre -20 et +20 degrés, en choisissant par convention l'orientation zéro dans la configuration nominale, c'est-à-dire quand le corps de crosse est aligné avec le canon du fusil. Selon cette première orientation autour d'un axe transversal, le premier angle d'orientation se mesure dans un plan longitudinal vertical, relativement à une direction horizontale. Cette orientation déplace le corps de crosse vers le haut ou vers le bas, sa partie arrière subissant l'amplitude maximale de déplacement relativement à un plan horizontal initial. D'autre part, par la construction décrite précédemment, il est très avantageux de noter qu'une fixation est possible pour tout angle d'orientation compris dans la plage prévue. En effet, le réglage est réalisé par un déplacement relatif continu d'une surface de réglage sur une surface de came. Le réglage permet ainsi d'être réalisé parmi une infinité de positions, toute valeur d'orientation pouvant être choisie dans la plage prédéfinie.The adjustment range can be limited by stops. It advantageously extends over a large range, for example extends from a first angle of orientation comprised between -40 degrees to +40 degrees, or even between -20 and +20 degrees, choosing by convention zero orientation in the nominal configuration, that is to say when the butt body is aligned with the gun barrel. According to this first orientation around a transverse axis, the first angle of orientation is measured in a vertical longitudinal plane, relative to a horizontal direction. This orientation moves the stock body upwards or downwards, its rear part undergoing the maximum amplitude of displacement relative to an initial horizontal plane. On the other hand, by the construction described above, it is very advantageous to note that fixing is possible for any angle of orientation included in the range provided. Indeed, the adjustment is carried out by a continuous relative displacement of an adjustment surface on a cam surface. The adjustment thus makes it possible to be carried out from an infinity of positions, any orientation value being able to be chosen within the predefined range.
A tout moment, l'orientation peut être modifiée en desserrant les vis de fixation jusqu'à atteindre la mobilité relative des deux éléments permettant le réglage d'orientation expliqué ci-dessus.At any time, the orientation can be modified by loosening the fixing screws until reaching the relative mobility of the two elements allowing the orientation adjustment explained above.
La coopération du corps de crosse 1 avec le deuxième élément de réglage 20 est réalisé de manière similaire. La portion de liaison en relief 3 du corps de crosse 1 est logée dans la portion creuse de liaison correspondante, de sorte que la surface de réglage 7 délimitant la portion de liaison en relief 3 vient au contact de la deuxième surface de came 26, permettant le déplacement relatif de deux composants. Lorsque l'orientation du corps de crosse est considérée comme satisfaisante, un dispositif de blocage et fixation est actionné pour solidariser les deux composants dans cette orientation choisie. Comme précédemment, le dispositif de blocage repose sur quatre vis, dont deux vis de fixation qui traversent respectivement les ouvertures 271, 272 du deuxième élément de réglage, de sorte à atteindre un serrage de la portion de liaison en relief 3 du corps de crosse par le rapprochement des deux parois 261, 262 opposées. En complément, deux autres vis 71 sont ajoutées pour venir en appui sur la surface de réglage de la portion de liaison en relief 3 et compléter la fixation.The cooperation of the
La plage de réglage peut être identique à celles mentionnées pour le premier réglage. D'autre part, ce réglage est de même avantageusement continu sur toute la plage prédéfinie, offrant une infinité d'orientations possibles. Le réglage d'orientations peut donc être très fin. Ce deuxième réglage d'orientation est réalisé selon un axe vertical, ce qui induit un réglage droite gauche du corps de crosse, d'amplitude maximale pour sa partie arrière.The setting range can be the same as mentioned for the first setting. On the other hand, this adjustment is likewise advantageously continuous over the entire predefined range, offering an infinity of possible orientations. The orientation adjustment can therefore be very fine. This second orientation adjustment is carried out along a vertical axis, which induces a left-right adjustment of the stock body, of maximum amplitude for its rear part.
Naturellement, l'invention ne se limite pas au mode de réalisation décrit. En effet, les éléments de réglage pourraient prendre d'autres formes que celles représentées. Notamment, les parties mâle et femelle de deux éléments coopérant entre eux pourraient être inversées par rapport au mode de réalisation décrit.Naturally, the invention is not limited to the embodiment described. Indeed, the adjustment elements could take other forms than those shown. In particular, the male and female parts of two elements cooperating with each other could be reversed with respect to the embodiment described.
De plus, toutes autres formes permettant par contact de surfaces selon le principe d'une came de modifier le positionnement d'un corps de crosse relativement à un élément de réglage, et indirectement à une poignée et/ou à un canon de fusil. Avantageusement, ce déplacement de surfaces en contact est continu, sur une plage prédéfinie, ce qui permet une infinité de positions possibles, et un réglage très fin. Un dispositif de blocage permet alors de fixer le corps de crosse dans chacune de cette infinité de positions. Avantageusement, une surface de réglage et une surface de came coopèrent entre elles comme décrit précédemment. Ces deux surfaces sont avantageusement de forme en portion de cylindre, pour induire un réglage d'orientation de type rotation, ou sensiblement proche d'une rotation.In addition, all other shapes allowing by surface contact according to the principle of a cam to modify the positioning of a stock body relative to an adjustment element, and indirectly to a handle and/or to a gun barrel. Advantageously, this displacement of surfaces in contact is continuous, over a predefined range, which allows an infinity of possible positions, and very fine adjustment. A blocking device then makes it possible to fix the stock body in each of this infinity of positions. Advantageously, an adjustment surface and a cam surface cooperate with each other as described previously. These two surfaces are advantageously in the shape of a portion of a cylinder, to induce an orientation adjustment of the rotation type, or substantially close to a rotation.
En variante, la surface de came pourrait présenter une autre forme qu'une portion de cylindre, pour provoquer un déplacement combinant un changement d'orientation et une translation par exemple. La surface de came pourrait aussi présenter une forme combinant plus d'une seule orientation. Elle pourrait être de type rotule, permettant un réglage d'orientation dans toutes les directions.Alternatively, the cam surface could have a shape other than a cylinder portion, to cause a movement combining a change of orientation and a translation for example. The cam surface could also have a shape combining more than one orientation. It could be of the ball joint type, allowing orientation adjustment in all directions.
Enfin, comme précisé, un mode de réalisation simplifié ne pourrait comprendre qu'un seul élément de réglage, et permettre alors une seule orientation de réglage. En variante, un seul élément de réglage pourrait permettre deux degrés de liberté, soit par une seule surface de came, soit par deux surfaces de came distinctes, et par exemple mettre en œuvre les deux orientations décrites précédemment. En variante encore, un réglage supplémentaire, ou en remplacement d'un autre réglage décrit précédemment, pourrait être obtenu par une orientation du corps de crosse autour d'un axe longitudinal, permettant ainsi l'inclinaison identique de l'ensemble du corps de crosse autour d'un axe longitudinal. En complément, le corps de crosse pourrait être réglable par une, deux ou trois translations, en complément des orientations décrites précédemment.Finally, as specified, a simplified embodiment could only include a single adjustment element, and then allow a single adjustment orientation. As a variant, a single adjustment element could allow two degrees of freedom, either by a single cam surface, or by two distinct cam surfaces, and for example implement the two orientations described above. As a further variant, an additional adjustment, or replacing another adjustment described above, could be obtained by orienting the stock body around a longitudinal axis, thus allowing the same inclination of the entire stock body around a longitudinal axis. In addition, the stock body could be adjustable by one, two or three translations, in addition to the orientations described above.
En résumé, la crosse de fusil selon le mode de réalisation comprend donc un corps de crosse 1, sur lequel sont disposés en partie avant une poignée et deux éléments de réglage 10, 20 intermédiaire. Le corps de crosse comprend de plus un busc en partie supérieure, et un talon en partie inférieure.In summary, the rifle stock according to the embodiment therefore comprises a
En complément de l'orientation avantageuse du corps de crosse relativement au canon, telle que décrite précédemment, il sera avantageux de combiner ce réglage avec un montage réglable d'un busc et un montage réglable d'un talon, ce dernier se composant avantageusement d'au moins deux surfaces d'appui indépendantes et pouvant se régler indépendamment l'une de l'autre relativement à la crosse de fusil.In addition to the advantageous orientation of the butt body relative to the barrel, as described above, it will be advantageous to combine this adjustment with an adjustable mounting of a comb and an adjustable mounting of a heel, the latter advantageously consisting of at least two independent bearing surfaces which can be adjusted independently of one another relative to the rifle stock.
Avantageusement, une liaison avec un busc peut être choisi de sorte que le busc est orientable selon une inclinaison autour d'un axe longitudinal, comme décrit par le document
Un talon est de plus monté au niveau de la face arrière 6 du corps de crosse 1. Avantageusement, le talon de fusil pourrait être tel que décrit par le document

Ainsi, l'invention porte aussi sur un talon en tant que tel, tel que décrit ci-dessus.Thus, the invention also relates to a heel as such, as described above.
L'invention ne se limite pas au talon décrit. Elle peut aussi être étendu à tout talon, de préférence un talon réglable par une mobilité permettant son réglage selon au moins un degré de liberté, voire deux, trois, quatre ou plus degrés de liberté.The invention is not limited to the heel described. It can also be extended to any heel, preferably an adjustable heel with mobility allowing its adjustment according to at least one degree of freedom, or even two, three, four or more degrees of freedom.
Avantageusement, le talon comprend deux éléments d'appui mobiles indépendamment l'un de l'autre. Avantageusement encore, ces deux éléments d'appui mobiles forment la totalité de la surface d'appui du talon (c'est-à-dire la surface fonctionnelle d'appui sur le corps du tireur).Advantageously, the heel comprises two support elements that are movable independently of each other. Advantageously again, these two mobile bearing elements form the entire bearing surface of the heel (that is to say the functional bearing surface on the shooter's body).
L'invention concerne également un fusil en tant que tel comprenant une crosse de fusil telle que décrite précédemment, une poignée, et un canon de fusil.The invention also relates to a rifle as such comprising a rifle stock as described previously, a handle, and a rifle barrel.
