Definitions

  • the invention relates to a bow for a stringed musical instrument and relates in particular to an improvement of the stick of this bow, making it possible to adjust its stiffness.
  • a classical bow is made up of a curved rod, widened at its head and provided, at the handle, with an adjustable positioning riser. A bundle of hairs is stretched between said head and said rise, by means of a screw-nut system.
  • the baguette is cut from a hard and resistant wood, quite rare, Pernambuco. More recently, it has been proposed to produce this rod in synthetic material, most often composite, for example based on carbon fibers or the like.
  • the qualities of a bow essentially depend on the characteristics of the stick, such as its camber and its greater or lesser rigidity.
  • the document DE-C-85 912 mentions a bow stiffened by the addition of an external metal wire making it possible to apply a prestress. In fact, the same bow can give satisfaction to one instrumentalist and displease another. The best instrumentalists even feel the need to change the bow depending on the work played, or simply on their sensitivity at the time. They are therefore brought to have several bows. However, good bows are expensive.
  • bows made of synthetic material if they are reproducible on an industrial scale, also have characteristics that are too similar, from one model to another, to satisfy all instrumentalists.
  • This variety which is possible at the artisanal level thanks to the know-how of the bow maker, raises difficulties on an industrial scale.
  • the invention makes it possible, among other things, to solve these problems by proposing a bow structure making it possible to vary the mechanical characteristics of the rod. It makes it possible in particular to give any bow provided with the improvement, an adjustable stiffness.
  • the invention essentially relates to a bow comprising a cambered rod, a first screw-nut system for the tension of the hair, said screw being actuated by a first button located at the end of the rod and said nut being housed in a mortise and linked to a rise, bow characterized in that said rod is hollow and comprises a longitudinal channel extending to the vicinity of its head and in that a stiffening core is housed in this channel and is linked to a second screw-nut system, coaxial with the first.
  • stiffening core any rod or wire liable to be stressed in tension or, on the contrary, in axial compression, by the screw-nut system, inside said longitudinal channel, in order to significantly modify the stiffness of said wand.
  • This improvement therefore allows an instrumentalist to adapt the bow to his playing or his repertoire.
  • the invention is particularly indicated for a bow comprising a rod made of synthetic material of the kind indicated above, since it makes it possible, from a reproducible rod structure with precise characteristics, to obtain a bow adaptable to demand of the instrumentalist.
  • a bow 10 comprising a cambered rod 11, of conventional appearance, and a bundle of hairs 12 stretched between the head 13 and a rise 14 with adjustable positioning along the handle 15 of said rod.
  • This handle rectilinear, has an octagonal section and serves as an upward guide 14 which comprises for this purpose an open groove with three longitudinal facets matching the shape of the lateral surface of the handle.
  • the rise 14 comprises a nut 16 engaged in a mortise 17 hollowed out in the rise. It is also pierced with a hole 18, axial, opening at the adjacent end 19 where there is a first button 20, secured to a screw 21. The latter is housed in the hole 18 and the mortise 17 and it is engaged in the nut 16.
  • This first screw-nut system (21-16) makes it possible to adjust the position of the riser 14 and, consequently, to adjust the tension of the hairs.
  • the rod 11 is hollow and has a longitudinal channel 24, extending over substantially its entire length, up to the vicinity of the head 13 and this channel houses a stiffening core 25, the latter being linked to a second screw-nut system (26-27), coaxial with the first.
  • This second screw-nut system is designed to stress said stiffening core in tension or in compression, depending on the assembly chosen. Depending on the stress exerted on said stiffening core, it is possible to modify and adjust the stiffness of the rod.
  • the nut 27 of the second screw-nut system is housed in a cavity 29, adjacent to said mortise.
  • the screw 21 of the first screw-nut system is tubular (it has an axial bore 31a) and traversed longitudinally by the screw 26 of said second screw-nut system.
  • the nut 27 is of the blind nut type and is fixed to the stiffening core 25.
  • the cavity 29 and the mortise 17 communicate by an axial hole 30, for the passage of the screw 26. This also extends through an axial bore 31b of the button 20, extending that of the screw 21 and it is fixed to a second button 32.
  • the second system vis- nut is arranged to work the stiffening web 25 in tension.
  • the latter must be anchored in the vicinity of the head 13, here by an enlargement 25a.
  • It can be made of synthetic material (nylon or other) or metal.
  • the two buttons 20 and 32 are separated by a spacer 34 made of anti-friction material, such as for example polytetrafluoroethylene.
  • the channel 24 containing the stiffening core is advantageously filled with silicone grease or a similar substance or material, favoring the sliding of said core.
  • the strip 11 can be made of molded synthetic material, which greatly facilitates manufacturing.
  • the second screw-nut system (26a-27a) is arranged to make the stiffening core 25 work in compression.
  • the latter is metallic.
  • the screw 26a is here constituted by a threaded portion of the corresponding end of said core, while the nut 27a is a segment with internally threaded blind hole. This segment is in abutment against an internal stop 36 of the rod, here an axial end wall of the cavity 29.
  • the nut 27a comprises, in this example, a hole 38 called "hexagon" for the operation of the system screw nut by means of a hexagonal section key 39, the latter being engaged through the tubular screw 21 and the button 20 of the first screw-nut system.
