Abstract

The support, having a stock (16) at one end and a flexible bow (2) at the other and a central channel in its upper face to form a bolt guide, is made in the form of a square-section hollow tube (1) with two or more lengthwise channels (10) in each of its faces (14) in which accessories (21, 22, 25, 26) can be adjusted and fixed. The pairs of channels are positioned symmetrically relative to the median planes of the tube's faces, and on the upper face lie on either side of the central bolt guide channel. Each channel is V-shaped in section, with its open end partly covered by the tube surfaces. The bow is fitted to one end of the tube by a head (3) in the shape of a rectangular stirrup with a fixing plate (4) which has a central guide hole (6) for the bolt.

Description

 The invention is in the field of crossbows and relates more specifically to a tree with a particular structure which allows it to support the accessory parts in a removable and adjustable manner.

 We know that one of the important parts of a crossbow is the barrel or arbrier carrying at one end a stick, and at the other end a flexible bow. A rope is attached to the ends of the bow and is hooked to a releasable retaining piece by a trigger, placed on the arbrier in front of the stick. This retaining piece keeps the string bandaged towards the rear of the bow, when the crossbow is cocked. Between said retaining part and the arch, the arbrier is hollowed out on its upper face with a groove for guiding the arrow.

 The crossbow is further provided with sighting devices mounted on the retainer as well as above the bow itself. For a good grip of the device, except for the butt stock on the shooter's shoulder, there is provided under the arbrier a vertical handle to the right of the trigger, and a little further towards the bow a horizontal handle with which the user can support the front part of the crossbow. Above the arbrier, near the stock, there is advantageously a curved plate acting as cheek support, for the comfort of the shooter.

 Finally the end of the arbrier, on the side of the arch, is equipped with a crutch of support on the ground for the arming of the apparatus.

 The crossbows thus produced have a determined structure and weight which cannot be suitable for users with different morphologies, or according to whether the apparatus is used for leisure or for competition.

 Until now, to modify the weight of a crossbow it was necessary to replace the stock, the barrel, or a handle, by an analogous piece but of different weight. The adjustment of the positioning of the various constituent elements indicated above, could not be done either in a simple way, so the manufacturers had to have a range of crossbows adapted to the different users, but also to the performances sought in particular in the precision and the length of the shot.

 The invention provides an interesting solution to this problem by proposing a standard arbrier, of simple construction, which makes it possible to modify the weight of the crossbow without replacing parts, depending on the strength and morphology of the user and which in addition authorizes the adjustment and positioning on demand, of the accessory parts linked to the arbrier.

 A main object of the present invention therefore relates to a arbrier carrying removable and adjustable accessories for crossbow, carrying at one end a stick and at the other end a flexible bow, and receiving a rope retaining piece as well as handles , a central groove being provided on the upper face of the arbrier for guiding the arrow said arbrier consisting of a hollow tube of quadrangular section provided on each of its faces with at least two longitudinal grooves used for fixing 'removable accessories which can be positioned in an adjustable manner along said arbrier.

 More precisely, the two grooves are symmetrically arranged with respect to the median planes of the arbrier and, on the upper face, said grooves frame the central groove for guiding the arrow.

Advantageously, the grooves have a V shape, the edges of which are capped by the faces of the arbrier.

 According to a particular characteristic of the invention, a bow head mounted at the end of the arbrier is formed by a rectangular stirrup in which the central part of the arch is housed and by a fixing plate to maintain the bow in the stirrup, an orifice being provided in the bow head, in line with the central arrow guide groove, an orifice which is profiled to form an integrated trajectory rectifier.

 More precisely, the trajectory rectifier has, on the side oriented towards the central groove, an orifice with three star-shaped entry wings with three points of widened width and greater than the thickness of the fins of an arrow and on the side oriented towards the front of the crossbow, a star-shaped exit slot with three points of width close to that of the ailerons, a profiled narrowing being formed inside the trajectory rectifier, between the orifice inlet and outlet slot.

 The various accessories of the crossbow are fixed on the arbrier by means of screws taking in the grooves of one of the faces of the arbrier.

Other particular characteristics and advantages of the invention will emerge from the description which follows of a nonlimiting exemplary embodiment in which reference is made to the appended drawings which represent
FIG. 1, a perspective view of a crossbow,
FIG. 2, a section view of the arbrier carrying removable accessories,
Figures 3 and 4, partial perspective views of the arbrier and the bow head.

 FIG. 1 is a general view of a crossbow, one of the main parts of which is the central barrel called arbrier and generally designated by the reference 1.

 The arbrier 1 is in the form of a hollow tube of quadrangular section provided on each of its four faces with two longitudinal grooves 10 symmetrically arranged with respect to the median planes of the arbrier.

 The lateral faces 11, the lower face 13 and the upper face 14 therefore each have these two grooves 10. However, the upper flat face 14 is also hollowed out with an additional groove 15, between the two lateral grooves 10 which surround it .

 We see in Figure 2 the V-shaped grooves 10, the edges of which are capped by flat parts formed by the faces (11, 13, 14) of the arbrier. At the base of each groove are provided longitudinal cells 12 which extend over the entire length and which reinforce the structure of the assembly.

 An arc 2 with double curvature is mounted at one end of the arbrier 1 by means of an arc head 3. This has the shape of a rectangular stirrup in which the central part of the bow. A fixing plate 4 holds the bow in the stirrup to which it is fixed by a set of screws 5. The bow head 3 projects above the upper face 14 of the arbrier. It is pierced right through with an orifice 6, in line with the central groove 15, for the passage of the arrow. This orifice is advantageously profiled to form a trajectory rectifier integrated into the arc head, as will be explained below.

 Still at the end of the arbrier 1, and on its lower face 13 is fixed a crutch 7 supporting the ground. The stand also serves as a support for an adjustable sight 8 developing above the bow head 3.

 At the opposite end of the arbrier, a stock 16 is mounted on two rods 17 movable inside a slide 18, which is engaged on the underside 13 of the arbrier by means of screws taking in the grooves 10 of said face.

 On this same end of the arbrier 1, but on a lateral face 11 is fixed in the same way by screws 19 taking in the slots 10, the rod 20 carrying a cheek support plate 21. It will be noted that this plate cheek support can pivot on the rod 20, the latter also being able to slide itself up and down along the lateral face 11, as well as in the longitudinal direction, these movements being made possible by conventional fixing methods not visible in the drawing.

 Thanks to the grooves 10 provided in the upper face 14 of the arbrier, a retaining piece 22 is used, which is also movable by sliding, for the attachment of the rope 23 and its release by means of a trigger 24 which overflows under the underside 13 of the tree. The connection mechanism between the retaining part and the trigger crosses the arbrier through the slot 15 and by a not shown notch, of limited length, provided in the lower face 13. Behind the trigger, on this lower face, is mounted a vertical handle 25, also movable thanks to the grooves 10.

 Finally, between this handle 25 and the arc 2, the lower face 13 always receives, according to the same displaceable method of attachment, a horizontal holding handle 26, advantageously made from the same profile as that of the arbrier. This handle 26 can pivot and tilt on its support axis 27. It is closed at its ends by plugs 28, and its internal hollow space can serve as housing for weights.

 Before using the crossbow, the shooter is therefore able to make the necessary preliminary adjustments, depending on the nature of the shot to be made, and especially according to its size, strength and morphology. The three parts that allow it to hold the crossbow in the correct shooting position are the stock 16 and the handles 25 and 26, all three adjustable in position. Thus the stick can be brought closer or away from the arbrier thanks to the telescopic rods 17. It will be noted that the slide 18 itself being removable and movable on the arbrier, the stick can be replaced by another stick of shape or structure different.

 The handle 25 is also movable under the arbrier and fixed at the desired distance from the trigger 24, depending on the size of the shooter's hand. The other support handle 26, shown parallel to the arbor 1 in FIG. 1, can be inclined relative to the support axis 27, which is also able to slide along the arbor to position the handle more or less in front of the crossbow depending on the weight of the set. This weight can be modified on demand by adding weights inside the handle 26, in the space accessible by the plugs 28.

 As seen in Figure 1 an aiming eyepiece 29 is mounted on the retaining piece 22 also movable on the upper face 14 of the arbrier, still thanks to the grooves 10. This changes the distance between the eyepiece and the viewfinder 8 which is itself orientable relative to the stand 7.

 Thus "prepared", the crossbow is ready to be armed. For this, in known manner, the crutch 7 is applied to the ground, and the rope 23 is pulled to hang it on the retaining piece 22. Finally, the arrow, not shown, is placed in position on the arbrier 1, at plumb with groove 15.

 The crossbow is then ready to fire. The bow head 3 advantageously has a particular device, also removable at the end of the arbrier, which is a trajectory rectifier 30, anti-beat, shown in more detail in FIGS. 3 and 4.

 Indeed, the orifice 6 provided in front of the central groove 15 on the side facing the retaining part, is a profiled orifice having three inlet wings 31 in the shape of a three-pointed star whose width is widened and clearly greater. to the thickness of the fins 32 of the arrow 33. (Figure 3). On the opposite side, that is to say on the side of the stand 7, that is to say towards the front of the crossbow, the orifice is reduced to an exit slot 34 in the shape of a star with three points, of width close to that of the fins (Figure 4). Between the inlet 31 and the outlet 34, the orifice 6 thus forms a profiled narrowing. If the arrow 33 is not correctly positioned on the arbrier, when the arrow is fired and penetrated into the orifice, the ailerons 32 incorrectly oriented at the start will return to a correct orientation when they cross the orifice 6 and will be perfectly aligned at the outlet with the slot 34, to ensure a perfect trajectory of the arrow.

 The arbrier previously described allows a quick and simple adaptation of the weapon to leisure and initiation to competition, as well as to the capabilities and morphology of the user. The accessories are adaptable and adjustable. The crossbow is therefore scalable without changing its general external appearance, the purity of the lines of which is due to the particular structure of the arbutus adds to the performance and advantages of the device.

 Of course, the invention has been described on the basis of a particular example to which it is not limited, but it also includes all other variant embodiments.
