Description

[0025] Further characteristics and advantages of the present invention will become more apparent from the description of a exemplary, but not exclusive, and therefore non-limiting preferred embodiment of a lighting kit and a weapon for sport use, as illustrated in the appended figures, in which:

[0026] FIG. 1 shows a side and schematic view of a weapon for sport use, and in particular of a fencing sword provided with the lighting kit according to the present invention and in a condition of use;

[0027] FIG. 2 shows a perspective view of a construction detail of FIG. 1;

[0028] FIG. 3 shows a perspective view of a foil in use in fencing, provided with the lighting kit according to the present invention;

[0029] FIG. 4 shows a perspective view of a sword in use in fencing, provided with the lighting kit according to the present invention;

[0030] FIG. 4a shows a cross-sectional view along the line IV-IV of the sword of FIG. 4 provided with the lighting kit according to the present invention; and

[0031] FIG. 5 shows a perspective view of a saber in use in fencing, provided with the lighting kit according to the present invention.

[0032] With reference to the accompanying figures, a lighting kit for weapons 2 in use in fencing is generally indicated with the reference number 1.

[0033] It should be noted that the present invention is applicable for weapons 2 in use in fencing, namely foil 3 (FIG. 3), sword 4 (FIG. 4) or saber 5 (FIG. 5).

[0034] Advantageously, the present invention finds advantageous application in the particular case of the sword 4 in use in fencing.

[0035] In greater detail, the kit 1 comprises a light source 6, preferably consisting of at least one LED 6a, which can be positioned at a handle 7 of the weapon 2 (FIG. 2).

[0036] The LED 6a, illustrated only schematically in FIG. 2 as of the known type, is adapted to generate a light L having electromagnetic frequency within the visible spectrum. This electromagnetic frequency is predetermined according to the various requirements in order to generate a light of a specific colour. In this way, during use, the weapons 2 of the two fencers U will have a light of different colour (for example a red and a blue) to be better identified.

[0037] Preferably, always referring to FIG. 2, the source 6 is arranged at an inner area of the bell-guard 8 of the weapon 2, which divides said handle 7 with the blade 9 of the sword.

[0038] However, it must be specified that the source 6 can be arranged in any area outside the blade, or associated with the jacket G of the user U.

[0039] The kit 1 also includes at least one guided propagation member 10 of light L generated by the source 6.

[0040] Such member 10 is advantageously disposed within a groove 11 formed on blade 9 of the weapon 2.

[0041] It should be noted that the foil 3 and the sword 4 and the saber 5 have a groove 11 that extends on a blade 9 surface. In particular, the groove 11 of the foil 3 and the sword 4 extends along the entire longitudinal extension of the blade 9, whereas for the saber 5 the groove 11 extends only to a portion of the blade 9 adjacent to the bell-guard 8.

[0042] Inside the groove 11 of the foil 3 and the sword 4, an electric cable 12 (visible in the section of FIG. 4a) extends, connecting with a switch 13 disposed on the tip 14 of the blade 9. As previously specified, such switch 13 enables indicating when the target is reached with the tip 14 of the weapon 2.

[0043] Note that in the view of FIG. 4a the blade 9 of the sword 4 has a V conformation in cross-section, in which said groove 11 is defined.

[0044] The guided propagation member 10 of light L comprises at least one optical fibre 15 extending along the longitudinal extension of the groove 11 formed on the blade 9.

[0045] The optical fibre 15 has a first end 15a connected to the light source 6 and a second end 15b opposed to the first 15a and close to the tip 14 of the blade 9.

[0046] In this situation, the optical fibre 15, in the preferred case of the sword 4 or the foil 3, extends along the entire longitudinal extension of the blade 9. In the case of the saber 5, the fibre optic 15 extends only partially with respect to the blade 9.

[0047] Advantageously, the fibre optic 15 has a length of 550 mm in the saber and of 880 mm in the sword, plus 150 mm within the bell-guard, and a thickness ranging from 1 to 3 mm in cross-section.

[0048] Still, fibre optic 15 is preferably of the type capable of propagating light along the entire respective longitudinal surface.

[0049] The kit 1 also includes constraint means 16 for firmly engaging the propagation member 10 within the groove 11.

[0050] The constraint means 16, better illustrated in FIG. 4a, comprise at least one resin or glue, transparent to light radiation to propagate the light L propagated by the fibre 15. Preferably, the constraint means 16 is made of EVA (Ethylene Vinyl Acetate), or reactive polyurethane-based glue.

[0051] The constraint means (resin or glue) is also distributed along the entire groove 11 so as both the fibre 15 and the electric cable 12 are embedded within it. In this way, the fibre 15 remains firmly engaged within the groove 11.

[0052] The constraint means (resin or glue) 16 further defines an annular portion 17 arranged about the second end 15b of the optical fibre 15 to diffuse the light along an annular path and concentric to the axis of longitudinal extension of the blade 9. Advantageously, the light L diffused at the tip 14 of the blade 9 is more visible because it is diffused on all sides of the blade 9.

[0053] The light source 6 is also connected to supply means 18 electrically connected to the LED 6a by means of suitable cables of a known type. Preferably, the supply means 18 (FIG. 1) comprise an electric battery that can be associated with the uniform (jacket or trouser) G of the user U. In this case, the electrical connection is implemented through a connector 19 located inside the bell-guard 8 (FIG. 2) and provided for the electrical connection of the signal transmission cable 12. It should be noted in FIG. 2 that the source 6 is suitably connected to said connector 19.

[0054] In addition, the kit 1 is provided with a processing logic unit 20 to activate and deactivate the light source by means of a manual switch (not shown in the attached figures) and according to a given electrical signal.

[0055] In other words, by means of the logic unit, the user U can enable or disable the source 6 to illuminate his or her weapon 2.

[0056] In addition, the logic unit manages the lighting according to a predefined software for managing the source 6. In this way, in accordance with a first possibility of operation, the light L is always switched on during the assault, even after the thrust.

[0057] In addition, the logic unit 20 can automatically turn off the light L at each thrust by the weapon 2. In this case, the unit 20 is suitably connected to the thrust assignment system that is activated by the switch 13 or the electric contact with the blade 9 of the saber 5.

[0058] Alternatively, an automatic switching on can only be provided after the thrust. In this case, the light L is not generated during the assault.

[0059] The present invention further relates to a lighting method for weapons 2 in use in fencing, comprising the steps of: providing the light source 6; housing at least one guided propagation member 10 of light L generated by the source 6 within the groove 11 formed on blade 9 of the weapon 2. Subsequently, the propagation member 10 is firmly constrained within the groove and the light source is electrically powered for generating a light radiation that propagates through said member 10.

[0060] The step of providing the light source is implemented by positioning at least one LED at the handle 7 of the weapon 2.

[0061] In this way, the LED generates the light L according to a predetermined electromagnetic frequency within the spectrum visible and corresponding to a respective colour.

[0062] The step of housing the propagation member 10 is implemented by providing at least one optical fibre 15 along the longitudinal extension of the groove 11. A first end 15a of the fibre 15 is then connected to the light source 6.

[0063] Advantageously, the light L generated by the LED is then passed along the fibre 15 and propagated through it to the outside.

[0064] Therefore, the light L diffuses from the entire outer surface of the fibre 15 and throughout its longitudinal extension.

[0065] The step of constraining the propagation member 10 within the groove 11 is implemented by distributing a liquid-phase resin or adhesive 16 on the optical fibre 15 and within the groove 11.

[0066] Subsequently, the resin-glue 16 is hardened and solidified to anchor the optical fibre 15 and the cable 12 within the groove 11. The resin-glue 16 is transparent to light radiation to facilitate the passage of light L towards the outside of the groove 11.

[0067] In addition, the resin-glue 16 realizes an annular portion 17 arranged about the second end 15b of the optical fibre 15 to diffuse the light along an annular path and concentric to the axis of longitudinal extension of the blade 9.

[0068] The source 6 is then activated and deactivated by means of a manual switch and according to a given operating logic.

[0069] In particular, the logic unit 20 manages the supply of the source 6 to keep the light L always switched on, or always switched on and switched off only after the thrust, or always turned off and activated after the thrust.

[0070] The present invention solves the problems of the prior art and has many advantages.

[0071] First, the kit 1 illuminates the blade 9 by making the weapon 2 more visible during the assault phases.

[0072] Even at high speed, typical the weapon handling by high-level athletes, the blade 9 can be clearly visualized by appreciating its movement.

[0073] This increased visibility thanks to the light L has advantages for the public as well as for the assault, and for the match administrator and individual athletes as well.

[0074] In fact, the match administrator can clearly visualize the movement of weapons by capturing more accurately and immediately the thrust movements in order to assign the score.

[0075] Even for individual athletes, the light L emitted by the blades 9 allows for greater visibility of the opponent's movement by exceeding the visibility limits provided by the masks.

[0076] In addition, the kit 1 is applicable to any weapon 2 in use in fencing, namely foil 2, sword 4 and saber 5, without having to change the structure of the weapon 2.

[0077] In fact, all the kit 1 components can be applied to previously determined zones of the weapon 2 such as the groove 11 formed on the blade 9 or the inner zone of the bell-guard 8. In this regard, it should be noted that such components do not interfere with the structure of the weapon 2, and therefore do not imply any change in the use of the weapon.

[0078] Finally, a further advantage of the present invention is due to the structural simplicity of the kit 1, which is made up of easily findable components, whose costs are therefore particularly low.

[0079] The lighting method can also be implemented in a simple and fast way, and therefore at very low cost, on weapons in use in fencing.
