Definitions

  • the invention relates to the field of archery practiced in clubs or for leisure.
  • the invention can advantageously be used indoors or outdoors and is suitable for archers of all levels.
  • a bow is made up of a handle, at the ends of which extend two branches on which a string is stretched.
  • bow grips differ if the archer is left-handed or right-handed.
  • a left-hander uses a handle adapted for a left-hander while a right-hander uses a handle adapted for a right-hander.
  • first category mainly used for leisure, in outdoor activities and/or intended for beginner archers.
  • This first category is generally made in a single block in materials resistant to impacts and bad weather.
  • the patent EP 1 070 933 describes a bow whose handle and branches are made in one piece.
  • the handle has an ergonomic shape in its center intended to accommodate an archer's hand. To do this, two distinct bow shapes must be made to cover the needs of left-handed and right-handed archers.
  • Another category of bows intended for more experienced archers practicing club archery, includes an additional part called a "grip" and intended to be fixed in the center of a handle body, so as to facilitate the grip of the bow and to increase the comfort and sensations of the archer.
  • the combination of the grip on the handle body thus makes it possible to form an arc handle.
  • a first form, intended for left-handers, comprises a left-handed handle body and a left-handed grip and a second form, intended for right-handers, comprises a right-handed handle body and a right-handed grip.
  • the patent US 4,966,124 describes a grip, in the shape of an elongated “U”, intended to fit onto the rear of the edge of a handle body.
  • the technical problem that the invention aims to solve is therefore to produce a bow that can be adapted to a left-hander and a right-hander, while allowing experienced archers to use such a bow without feeling a drop in comfort or performance. shooting.
  • Each arm has a recess forming a shooting window and means for fixing the grip.
  • the handle body has, for its part, a plane of symmetry so that the archer can select one of the arms to fix the grip and the other arm to form the shooting window.
  • the selection of each arm is carried out by tilting 180° around an axis of the plane of symmetry, in order to obtain a handle suitable for a left-handed or a right-handed person.
  • the design of the grip body allows an archer to adapt the bow to his guiding hand in a limited number of steps and without having to disassemble either the limbs of the grip body or the bow string. . Simply disassemble the grip, turn the bow over and reassemble the grip on the opposite arm.
  • the grip fixing means correspond to at least one hole opening into the recess of each arm; the at least one through hole being intended to accommodate at least one screw penetrating the grip.
  • the archer can carry out a simple screwing operation.
  • the grip is thus less likely to move or separate from the handle body when the bow undergoes twisting and/or deformation forces linked to shooting an arrow.
  • the grip fixing means are also configured to fix an arrow rest and/or a Berger button in the recess in the arm forming the shooting window.
  • a “Berger button” or “compensator button” is composed of an internal spring which presses on the arrow tube.
  • the Berger button acts as a shock absorber for the arrow when it is propelled and reduces its undulations.
  • a right-handed or left-handed archer can use the grip support means opposite to those already occupied by a grip to attach additional grip accessories. way to improve your shooting experience. This therefore makes it possible to adapt the bow to the level of the archer by adding or not accessories for compensation and/or stabilization of the shot.
  • the grip support means correspond to two through holes opening onto the side faces of the handle body.
  • the grip can be fixed laterally on the handle body, unlike the grips of the state of the art, which fit onto the rear face of the handle body.
  • the grips can therefore be one-piece, unlike the grips of the state of the art, which have a U shape.
  • the one-piece grips are thus generally more resistant to deformation or breakage.
  • each arm has second means for fixing a clicker and/or a viewfinder.
  • a clicker corresponds to an accessory producing a sound signal indicating to an archer that he must release his arrow.
  • Such an accessory allows an archer to make his shooting movement more fluid.
  • the fact of using a single type of fixing means for several different accessories makes it possible to reduce the production costs of the handle body.
  • the invention also relates to a grip intended to be mounted on a handle body as described above.
  • the upper part has a protrusion on its first side face, intended to form, with the recess of an arm of said handle body, the firing window.
  • Such a grip is also a part which is easy to handle.
  • fixing can be carried out by placing the grip on one side of the handle body and aligning the grip fixing means on the handle body.
  • the grip fixing means correspond to at least one threaded blind hole configured to receive at least one fixing screw.
  • the grip also includes a threaded tube configured to accommodate a stabilizer located at a lower part of a rear face of the grip.
  • the stabilizer can be integrated on the bow handle without having to make a recess in the handle body, which would have the effect of weakening the handle body which is subjected to strong torsional stresses when the bow is drawn and when the arrow is released.
  • the invention also relates to an ambidextrous bow grip comprising a grip body and a grip as previously described.
  • the invention finally relates to an ambidextrous bow comprising a handle as described above, at the ends of which two branches are mounted, and a rope stretched at the ends of the two branches.
  • a bow comprising such a handle body and such a grip is very versatile because it can adapt to all levels, from a beginner archer who does not use accessories to an experienced archer who practices shooting. archery in competition and who uses numerous accessories such as a stabilizer, a Berger button, a sight and/or a clicker.
