Definitions

  • the subject of the invention is a fencing blade and in particular a foil blade and its manufacturing process.
  • the foil blades (1) are arranged along their length with one or more grooves (1.1) opening outwardly and allowing positioning and fixing by gluing or other conductive means (2) in the form of wire going from the handle to the end of the blade while being connected to a low voltage current source.
  • a foil of the aforementioned type As illustrated in Figure 1 a foil of the aforementioned type.
  • the foil blade has in its width one or more U or H sections depending on the number of grooves made.
  • the profile of these grooves can be either substantially rectangular, or trapezoidal to retain the conductive wire or wires.
  • the establishment by gluing turns out to be long, impractical to carry out, the wire remaining visible and being able, according to the attacks and the deformation of the blade, to peel off and detach from its housing and appear externally. So you have to change the foil.
  • the foil blade is produced by stretching and hot forging then by performing a complementary grinding operation to produce the longitudinal groove or grooves. These operations are in practice long and expensive and require a large workforce to carry them out. It is also then necessary to position the conductive wire by the above-mentioned gluing operation.
  • the aim sought after according to the invention was therefore to design a new fencing blade and in particular foil, which is easy to manufacture, while improving its qualities of rigidity despite the stresses of the weapon and its deformation in condition of use.
  • Another aim sought after according to the invention was in the design of a foil blade where the operation of bonding the wire or conductive wires is eliminated, while facilitating and ensuring good holding and good positioning of the one or more son.
  • Another aim sought after according to the invention was to limit and reduce the operations for manufacturing foil blades in particular and therefore to reduce manufacturing costs while obtaining an improved surface finish.
  • Another aim sought after according to the invention was to design a foil blade in particular, arranged with one or more means ensuring immediate and visual self-control in the event of deterioration of the condition of the foil blade.
  • the foil blade is remarkable in that it has, in its thickness and without apparent opening, over its entire length an internally hollow section allowing the engagement and positioning of one or more conductive wires.
  • the foil blade has an preferably rectangular outer section with rounded angles, decreasing from the attachment zone of the handle at its end.
  • the method of manufacturing the foil blade consists in making the blade from a piece of steel, beforehand carrying out a drilling operation in said piece according to a pre bore diameter. -bench, to realize and form the foil blade from the aforementioned piece by cold forging and drawing until obtaining the desired length of the blade, with an internal bore sufficient for the engagement and the passage of one or several conductors.
  • the foil blade is arranged internally to receive a means or an expandable material capable of engaging in cracks or other deterioration occurring on the blade as a result of its use said means or expandable material protruding externally thereby ensuring by visual self-checking by the user the deterioration of the blade.
  • the fencing blade and in particular the foil (3) according to the invention is shaped over its entire length along an preferably rectangular external section with rounded edges and without visible opening, hollow internally (3.1) allowing engagement, centering and holding one or more conductive wires (4) thus going from the handle to the end of the blade.
  • the foil blade thus has a tapering external section from the handle attachment zone to its end. It can nevertheless be of constant section or combine an initial area of decreasing section extending into an area of great length of constant section.
  • the internal receiving bore (3.1) of the conductor wire or wires (4) is advantageously constant over its entire length or may initially have a conical section extending to promote the engagement of the wire or wires. giant by a regular cylindrical section.
  • the diameter of the bore may be substantially greater than the diameter of the conductor wire (s) to ensure their tight engagement and adjustment. There may also be a slight clearance to allow movement of the wire or wires in the bore in order to take account of the deformations of the weapon during its use.
  • the foil strip thus described according to the invention is implemented by an original manufacturing process which consists of the following phases. From a piece of steel, the characteristics of which have been previously chosen, a drilling operation is carried out over the entire length of the piece, thereby obtaining an initial bore of predetermined diameter. The piece is then deformed and transformed to obtain the final length of the blade by carrying out cold forging and drawing operations until the final shapes and characteristics of the blade are obtained. By implementing these operations, the internal bore (3.1) has a smaller diameter but sufficient for engagement and the passage of one or more conductive wires.
  • the forging and cold drawing is carried out by any machine known from the state of the art. In order to keep a bore of constant and calibrated diameter, it is possibly possible to use a forging olive known from current cold forging techniques.
  • the foil blade thus described is arranged with means (5) capable of ensuring visual self-checking by the user of the condition of the weapon and of its possible deterioration. .
  • this means consists of a material having characteristics of expandability.
  • This flexible material can be made from synthetic products or rubber or the like and be in the form of a paste.
  • This material is injected under pressure in a fluid state into the bore of the foil blade which can simultaneously undergo a heating operation on all or part of the blade to facilitate the introduction and flow of the material in all of the cavity thus formed.
  • This cold material expands and retains an elastic memory to introduce itself naturally into any deterioration, crack or crack likely to appear in the thickness of the blade.
  • This expandable material can be produced from any material having an elastic deformation memory when cold. This material which is injected into the bore of the blade is naturally compressed and the appearance of any defect allows its natural expansion and the filling of cracks, cracks and others.
  • this expandable material surrounds the conductive wire or wires previously introduced, contributing to their maintenance and positioning.
