Description

 Battue band with adjustable rise for rifle in particular.

 The invention relates to the technical sector of firearms.

 It is known practice to equip rifles with a profiled battue strip forming an eot ramp intended to allow a more open and therefore faster aim. Such soundtracks used in particular for so-called battue shots.

 These bands are fixed to the barrel by welding or screwing very substantially at the level of the wooden front.

Generally, they have, along their median axis, a V-shaped longitudinal groove to ensure aiming.

 It has also been proposed to equip a battue strip with an adjustable rise in the form of a profiled block mounted with the ability to move along a curved profile presented by said ramp. A notching system ensures the block in position of the block acting as a rise. It is understandable that this adjustment system is imprecise. In addition, it is not possible to retract the rise.

 The invention has set itself the aim of remedying these drawbacks by producing a threshing strip shaped to receive an easily adjustable rise in a very precise manner on the one hand, and capable of being retracted, on the other hand. It is thus possible for the user to regulate his shot very precisely.

 The problem is solved in that the strip has in its front part a notch in which is mounted free sliding with position adjustment capacity, a profiled plate capable of acting as a rise.

 Advantageously, the plate has in its thickness, an axial lumen cooperating with at least one locking means in position.

 In one embodiment, a pin is engaged in the thickness of part of the strip through 0e 1 G the uni er to guide the wafer, in combination with the locking means. The notch is formed across the entire width of the strip to give free digital access to the side edges of the insert. The lateral edges of the plate are striated.

 In another embodiment, the end of the plate, located on the side of the barrel, is arranged to be screwed into a wheel accessible from the outside of the strip and immobilized in translation, so as to ensure, under a rotation effect, the corresponding displacement of the wafer. The wheel is mounted in a housing formed in axial alignment with the notch receiving the wafer, to be in contact with a part of the barrel, an opening formed in the strip being in communication with the housing of said wheel to make it accessible.

 According to other characteristics, graduations are formed near the notch in correspondence with the lateral edges of the plate. The plate has axially, in its upper part capable of projecting from the strip, a V-shaped notch. The plate and the notch are dimensioned so as to allow the said plate to be completely retracted.

The invention is set out below in more detail with the aid of the appended drawings in which
Figure 1 is a side view of a rifle equipped with a battue strip, according to the invention.

 Figure 2 is, on a larger scale, a partial view in section of the battue strip at the level of the rise according to a first embodiment.

 In order to make the object of T'inventicn more concrete.

it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.

 The battue strip designated as a whole by is fixed, in a known manner, to the rifle barrel (C) very substantially at the outlet of the breech box.

at the level of the wooden front. The band is fixed to the barrel by any known means.

 According to the invention, the strip has in its front part, and from its upper edge, a notch (la, able to receive free sliding a plate (2) shaped to act as a rise. The notch (la is inclined very substantially parallel to the front face of the strip (1) and is formed over the entire width of said strip.

 The plate (2) has in its thickness, an axial lumen (2a) cooperating with at least one locking means in position (3) such as screws. This screw (3) is engaged in a tapped hole <lb) formed perpendicular to the notch (1a) receiving the plate (2) so as to allow the engagement of said screw through the lumen (2a). The screw head (3al bears against the plate (2) while being embedded in a recess concentric with the tapped hole (lb).

 Based on this basic design, there are essentially, but not limited to, two embodiments.

 In the embodiment of Figures 2 and 3, a pin <4) or equivalent member, is engaged in a hole (lc) through the lumen (2a) to guide the wafer (2) in combination with the screw (3).

 The width of the plate (2) is at least equal to the width of the notch (la) so that it is possible to have digital access to the lateral sides of said plate (2) for its displacement in translation and therefore of its adjustment. To facilitate the mar.ipulaticn, the lateral sides of the plate (2) can present grooves (2b).

 Under these conditions, it suffices to unlock the screw (3) and to slide the plate (2) which is guided by its light (2a) in combination with the pin (4), until the desired height adjustment of said plate corresponding to the shooting correction to be made.

 In the embodiment illustrated in FIGS. 4 and 5, the guide pin (4) is eliminated, the rear part of the plate (2) on the side of the barrel (C), being arranged to be subjected to an operating wheel (5 ), accessible from outside the strip (1). For this purpose, the wheel (5) is mounted in a recess or recess (ld) formed in axial alignment with the notch (la)> so that a part of said wheel is in contact with a part of the barrel, for ensure its immobilization in translation.

 The wheel (5) is screwed onto a threaded shank (2c) which is axially presented by the plate (2) and has a striated cylindrical part (5a) and a frustoconical part (5b) capable of being in contact with the corresponding part of the barrel as indicated. An opening (le) is made in the strip (1) while being in communciation with the housing (ld) of the wheel so as to have free digital access to the striated part (5a) of said wheel (5).

 I1 therefore appears that by acting in rotation on the wheel (5), the screw (3) being released, the concomitant displacement in translation of the wafer (2) is caused, it being recalled that said wheel is immobilized in translation in its housing ( ld) by the barrel (C).

 Advantageously, in one or the other embodiment described and illustrated, the plate (2) and the notch (la) are dimensioned so as to allow the plate to be completely retracted, if necessary.

 Finally, the plate (2) which acts as a rise, has axially, a V-shaped notch (2e) constituting, in a known manner, the viewfinder. It is also planned to practice, near the notch (la), in correspondence with the lateral edges of the plate, graduations or other marking lines capable of ensuring visualization of the adjustment carried out.

The advantages are clear from the description, and in particular it is emphasized
- The simplicity of realization.

 - The precision of the adjustment.

 - The possibility of retreating the rise.

 - The ease and speed of adjustment.

 - The aesthetics of the entire battue strip which is not "weighed down" by the presence of the rise.
