- Figure 1 1 is a schematic view of the second support part of the rifle heel according to an embodiment of the invention in which said second support part comprises four bores aligned in a vertical direction.
- longitudinal axis means an axis parallel to the longitudinal axis of the rifle on which is mounted or intended to be mounted the rifle butt or the longitudinal axis of the barrel of the rifle on which is mounted or intended to be mounted the heel.
- vertical axis is meant an axis perpendicular to a longitudinal axis and forming with said longitudinal axis a plane parallel to a median plane of the rifle.
- a median plane is generally a plane of symmetry or substantially of symmetry of a rifle, in addition to some portions offset due to the adjustments of the bearing surfaces, which will be described below.
- the vertical axis is oriented substantially from bottom to top.
- transverse axis is meant the axis perpendicular to the vertical axis and to the longitudinal axis. It is also perpendicular to the median plane, in particular of symmetry of the aforementioned rifle.
- the longitudinal, vertical and transverse axes can be defined as a variant with respect to a base of the heel.
- the axis longitudinal is substantially perpendicular to the plane of the base, the transverse axis is oriented along the width of the base in the plane of the base and the vertical axis is oriented along the length of the base in the plane of l 'base.
- the rifle heel 1 comprises at least two support parts 4, 5 intended to come to bear on the body of the user. These two support parts extend in the vertical direction, the upper support part 4 is intended to come into abutment close to the shooter's shoulder, and the lower support part 5 extends below , especially up to the vicinity of the shooter's chest.
- the rifle heel 1 comprises a device 10 for adjusting the position and / or the orientation of the two support parts 4, 5. These two support parts 4, 5 are distinct from each other . They are movable relative to each other, at least partially independently.
- the adjustment device 10 advantageously makes it possible to adjust the position and / or the orientation of the two support parts relative to the rifle body and / or the position and / or the orientation of a first support part 4 with respect to a second support part 5.
- Each support part comprises at least one bore 41 for fixing it to the adjustment device 10, in particular a bore in a direction along a longitudinal axis.
- the bores 41 are designed to allow the passage of a screw through the support part which will cooperate with the adjustment device 10 to allow the connection between the support area and the adjustment device, as illustrated in figure 9.
- the adjustment device 10 comprises a base 2.
- the base 2 is designed to be fixed to the end of a rifle butt.
- the two support parts 4, 5 are mounted on the same base.
- one of the two support parts or the two support parts 4, 5 are mounted movably on said base 2.
- the two support parts are mounted mobile on the same base.
- at least one of the two support parts is mounted indirectly on the base 2 by means of a connector 3.
- the adjustment device 10 allows the mobility of the first support part 4 movable along a translation along a transverse axis T.
- the adjustment device 10 rests on a connector 3 which then comprises at least one through groove 31 extending along a transverse axis T.
- a screw inserted in the bore 41 of the support part 4 passes through the through groove and can then be tightened or not in a nut positioned behind said groove.
- the screw is not tightened, it is free to move along said groove 31, giving the first support part 4 freedom of movement along a transverse axis T relative to the base 2, and indirectly relative to the second support part 5 and more generally relative to the stock of a rifle and to the rifle itself.
- the adjustment device 10 rests on a second groove 31 disposed on the connector 3 extending transversely parallel to the first groove and designed to receive a screw passing through a second bore 41 of the first part d '' support 4.
- the adjustment device 10 allows the mobility of the first movable support part 4 according to a rotation around a longitudinal axis L. This mobility thus represents a second degree of freedom of the first support part 4.
- This rotational mobility can be achieved by pivoting the first movable part around the screw present in the bore 41 of the first part, in an embodiment which would be simplified with a single screw and a single bore 41.
- the two parallel through grooves allow such rotation of the first support part 4 about a longitudinal axis by means of a clearance provided around the screws positioned in each groove, which allows the vertical alignment of the two screws.
- FIG. 4 illustrates such a configuration, the result of which is a rotation of the first support part 4 around a longitudinal axis.
- the grooves 31 of a connector 3 of the adjustment device 10 cooperating with a support part thus authorize both the translation of the first support part 4 along a transverse axis T and both a rotation of the first support part 4 around a longitudinal axis.
- the adjustment device 10 also allows the mobility of the first support part 4 according to a rotation about a transverse axis T. Such mobility thus represents a third degree of freedom of the first d 'support, and a setting similar to a pitch setting. According to the embodiment, this rotation is possible by the mobile link between the connector 3 and the base 2.
- the base 2 comprises a portion 23 having a curved hollow shape, particularly visible in FIG. 5.
- Said curved shape is preferably a concave shape, that is to say a rounded shape towards the inside of the base. It is akin to a half cylinder with a transverse axis.
- the connector 3, particularly visible in FIG. 6, comprises a first portion 32 intended to cooperate with a support part 4.
- This first portion 32 comprises the two grooves 31 described above.
- the connector 3 comprises a second portion 33 intended to cooperate with the hollow portion 23 of the base 2.
- said second portion 33 has a shape complementary to the shape of the portion 23 of the base 2, in particular a convex shape, that is to say rounded outwards, complementary to the concave shape of the base 2.
- the positioning of the second portion 33 in the corresponding portion 23 of the 'base allows their two substantially cylindrical surfaces to come into contact, and to be able to occupy a tight and fixed configuration and a loose and adjustable configuration.
- the connector is movable relative to the base by a sliding of the two contact surfaces 23, 33 mentioned above, therefore according to a rotation about a transverse axis.
- a transverse screw is able to pass through the base 2 to cooperate with the connector 3 at its second portion 33, making it possible to fix its position and reach said tight and fixed configuration.
- the first support part 4, fixed to the connector 3, is therefore adjustable relative to the base 2 according to a rotation about a transverse axis T.
- the second portion 33 of the connector 3 comprises two threaded bores on its face opposite to its convex part described above, forming a means of fixing the first support part 4.
- these two threaded bores are positioned respectively opposite each groove 31, so that receive the screws passing through the first bearing surface 4 and the two grooves 31, and allow their tightening, thus forming nuts for these screws.
- the first bearing surface 4 can occupy a tight configuration, in which it is not movable relative to the connector 3, and an adjustment configuration, by loosening said screws, thus allowing the adjustment of the first surface d 'support according to the first two degrees of freedom described above.
- the second bearing surface 5 is mounted on the same base via another similar connector 3, according to an adjustment device 10 which allows the same degrees of freedom and adjustment than the first bearing surface 4.
- the adjustment device 10 may include means allowing the mobility of a support part relative to the base in a translation along a vertical axis V, in particular a slide connection.
- the adjustment device 10 allows the mobility of the base 2 relative to the rifle body 100 along a translation along a vertical axis V.
- the base 2 comprises a through groove 22 on one of its faces, in particular on a face perpendicular to a longitudinal axis L, in particular on the face opposite to the face oriented towards the support parts 4, 5.
- the groove 22 s' extends along a vertical axis V.
- the vertical groove V extends between two portions 23 having a curved shape of the base 2.
- the adjustment device 10 can comprise a base 6 designed to be fixed to a rifle body XX.
- the base 6 comprises at its distal end, a projection 61 designed to be inserted inside the vertical groove 22 of the base 2.
- the vertical groove 22 of the base 2 is longer than the projection 61 of the base 6 so that the projection 61 is free in translation along the vertical groove 22 of the base 2.
- Said projection 61 comprises a through groove 62 passing through the projection 61 along a transverse axis T and extending along the projection 61 along a vertical axis V.
- the base 2 includes a bore 24 designed for the passage of a screw 64 through said bore 64 and through the groove 62 of the projection 61.
- This screw 64 advantageously makes it possible to block the mobility of the base 2 relative to the base in a direction along a longitudinal axis L.
- the base 2 is then movable relative to the base 6 and / or relative to the rifle body 100 in the direction of the groove 62 of the projection 61, preferably the vertical direction V.
- the base could be movable differently relative to the butt of the rifle, for example according to a rotation around a longitudinal and / or transverse axis.
- the base 6 comprises a locking means 63 comprising a thread arranged behind the projection 61 and arranged to cooperate with a thread of the screw 64.
- the screwing of said screw 64 then makes it possible to tighten the locking means 63 of the base against the base 6 and block the mobility of the base 2 relative to the base 6 by friction.
- Each support part is designed to come to bear on an area of the body of a shooter when the latter fires or aims with the rifle comprising the rifle butt.
- Each support part 4, 5 preferably comprises a flat surface intended to come into contact with the body of the user. Said surface may include a compressible material for the comfort of the user.
- Each support part can include any surface anatomical, is removable and can be replaced by a bearing surface of different property, for example of different shape and / or of different material.
- the invention has been illustrated with two support parts 4, 5. As a variant, it could comprise three or more distinct parts, at least one being mobile, or even at least two being mobile, or even all of the parts being movable.
- the two bearing surfaces are movable, independently adjustable, relative to a common base.
- a single support part could be movable relative to the second, not necessarily by means of a base.
- other devices could be envisaged to implement the mobility of a support part of the heel.
- this mobility can be done according to other choices of degrees of freedom than those described above.
- the invention relates to any heel comprising at least one part which is movable relative to another part.
- mobility is understood in the sense of a possible position adjustment, it being understood that the two or more adjustable parts (mobile) necessarily occupy a fixed configuration for the practice of shooting. This mobility to allow adjustment is possible according to at least one degree of freedom, or even two, three, four or more degrees of freedom.
- the heel comprises two movable parts independently of one another, an upper intended for support at the level of the shooter's shoulder and the other lower at the level of his chest.
- these two movable parts form the entire surface of the heel (that is to say the functional surface of support on the body of the shooter).
- At least one of the two support part 4, 5 comprises at least three bores 41 aligned vertically, preferably at least four bores 41 aligned.
- This alignment makes it possible to adjust the position of the support part according to a vertical axis by changing the bore (s) which will cooperate with the adjustment device 10.
- each bore 41 is separated from an adjacent aligned bore by a distance of between 0.5 cm and 1.5 cm , preferably about 1 cm.
- This vertical mobility thus corresponds to a discontinuous translation in the vertical direction.
- the alignment of the bores can be provided in a direction other than the vertical direction, in order to provide an adjustment axis in another direction. In another variant, it may comprise several bores positioned in a different manner, not necessarily aligned.
- the first support part 4 comprises a width (along a transverse axis T) of between 4 and 6 cm and a length (along a vertical axis V) of between 6 and 7 cm.
- the second support part 5 comprises a width (along a transverse axis T) of between 4 and 6 cm and a length (along a vertical axis V) of between 6 and 8 cm, preferably around 7 cm.
- the support parts 4, 5 comprise a rigid plate, preferably an aluminum plate, the thickness of which (along a longitudinal axis L) is between 3 and 5 mm.
- the invention also relates to a rifle 200 comprising such a rifle body 100 or such a rifle butt 1. It also relates more generally to any weapon comprising a heel as described above.
