[0001] The present invention relates to a blade, particularly for fencing and therefore
for the disciplines of foil, saber, and épée.
[0002] Currently, in the practice of fencing, and therefore in the three disciplines it
includes, conventional implements are used all having a metal blade with which a handle
and a hilt are associated together with electrical devices for detecting the occurrence
of a thrust on the metallised jacket of the opponent.
[0003] These conventional implements have the considerable drawback due to possible breakage
of the metal blade during sports practice, with possible extremely severe injury to
the opponent's body due to the penetration of the blade stump in said body, as indeed
has occurred.
[0004] The danger of breakage lies in the fact that it occurs when the point of the blade
is already in contact with the jacket of the opponent, and particularly when said
blade has assumed a curved shape due to the pushing force that the athlete applies
during the thrust.
[0005] This penetration is facilitated by the fact that, since the composition of the blade
is not perfectly uniform, it breaks along an axis that lies diagonally to said blade,
in a manner termed a flute-mouthpiece breakage.
[0006] This problem of blade breakage is currently increased by the higher athletic level
of the competitors and therefore by the greater force of the thrust.
[0007] As a partial solution to this drawback, the jacket or mask of the athletes have been
strengthened; however, this solution has not been found adequate.
[0008] A principal aim of the present invention is therefore to solve the described technical
problems, eliminating the drawbacks of the mentioned prior art by providing an implement
for fencing that is reliable and safe in use and avoids dangers to the safety of the
athletes in case of blade breakage.
[0009] An important object of the invention is to provide an implement that can be used
in international contests and can therefore be electrified.
[0010] Another important object is to provide an implement that can be manufactured with
conventional machines and facilities and which is light in weight.
[0011] Another object is to provide an implement having low manufacturing costs that allow
its rapid and wide diffusion.
[0012] According to a preferred embodiment of the invention, there is provided a blade,
particularly for fencing, which is characterized in that it is constituted by a single
body obtained by stratified application of composite material made of resin and glass
fiber or synthetic fibers that forms an internal channel. An electrically connectable
metallic point and tang are associable with the ends of the single body.
[0013] The characteristics and advantages of the invention will become apparent from the
following detailed description of a particular but not exclusive embodiment thereof,
described and illustrated in the accompanying drawings only by way of non-limitative
example, wherein:
figure 1 is a side elevation view of the blade according to one preferred aspect of
the invention;
figure 2 is a sectional view of the blade, taken along the plane II-II of figure 1;
figure 3 is a sectional view of the blade, taken along the plane III-III of figure
1;
figure 4 is a sectional view of the blade of the preceding figures, taken at an end
with which a tang is associable, in which the tang is also shown in cross-section;
figure 5 is a sectional view of the blade of the preceding figures, taken at an end
with which a point is associable, in which the point is also shown in cross-section.
[0014] With reference to the above figures, the reference numeral 1 designates a blade,
which is particularly usable for fencing in its various disciplines, namely foil,
saber, and épée.
[0015] The blade is constituted by a single body 2 obtained by stratified application of
a composite material made of resin and glass fiber or other synthetic fibers.
[0016] These layers are preferably applied along an axis that is parallel to the longitudinal
axis 3 of the blade 1, so as to achieve good uniformity.
[0017] The body 2 has a frustum shape that allows it to be flexible during use.
[0018] A first end 4 having a larger diameter and a second end 5 having a smaller diameter
are thus formed.
[0019] The body 2 is provided so as to internally form at least one channel 6 that allows
the passage of appropriate cables or wires.
[0020] A metal tang 7 is associable at the first end 4 and has a first stem 8, insertable
in the channel 6, an annular ridge 9, abutting at the edge 10 of the first end 4,
and a first cylindrical head 11 for connection to a hilt and/or a handle.
[0021] The tang 7 has a first axial hole 12 allowing the passage of the wires or cables
arranged inside the channel 6.
[0022] A point 13 made of metal is associable at the second end 5 and allows electrification;
it can therefore have a second stem 14 insertable in the channel 6 and a second head
15 having essentially the shape of a truncated cone in a transverse cross-section.
[0023] As an alternative, the point can be of the type comprising a bush rigidly coupled
to the second end 5 by means of a disk and provided with adapted conventional means
for sending an electric signal.
[0024] It has thus been observed that the invention has achieved the intended aim and objects,
a blade for a fencing implement having been provided that is reliable and safe in
use since, while having optimum flexibility, in case of breakage it has a shearing
section that lies transversely or essentially perpendicular to the longitudinal axis;
this means that, even if the broken tip of the blade makes contact with the jacket
of the opponent, it causes no damage, since the deeper the breakage, the wider the
diameter of its flat cross-section.
[0025] The presence of the internal channel allows to give good elasticity to the blade
and allows to electrify it, so as to allow use of the sports implement even in international
contests.
[0026] Finally, the blade thus obtained is light in weight and has low manufacturing costs
and at the same time has lower production costs than conventional metal blades.
[0027] The blade according to the invention is of course susceptible of numerous modifications
and variations, all of which are within the scope of the same inventive concept.
[0028] The materials and the dimensions that constitute the individual components of the
blade may of course be the most pertinent according to the specific requirements.
[0029] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
