[0001] The present invention refers to a helmet for sporting activities, in particular for
motorcycling.
[0002] The near totality of helmets currently produced for sporting activities have aeration
systems allowing to convey air from the outside to the inside of the helmet.
[0003] Such a need is linked to the fact that helmets, in particular for motorcycle use,
require a high degree of protection with remarkable abilities to absorb impact-deriving
energy. To attain this result, caps with ever wider covering surfaces, and expanded
and non-expanded materials are used that however entail, among other things, high
insulation capacity.
[0004] Moreover, above all for helmets used at high speeds, there has to be ensured utmost
air tightness (sealing), in particular between cap and visor, to reduce aerodynamic
noise and avoid lacrimation and other inconveniences to the wearer.
[0005] These features entail the reaching of temperatures internal to the helmet that may
exceed the 50 C° and accumulations of relative humidity of up to 90%. Just in order
to obviate these problems, helmets manufactured according to the known art comprise
aeration systems, essentially consisting in ports made in the front portion of the
helmet cap, equipped with conveyors for introducing air at ambient temperature.
[0006] Moreover, usually other ports are made in the rear/bottom portion of the cap, with
the purpose of drawing heated air.
[0007] Therefore, aeration systems have the task of producing a drop in temperature inside
the helmet, and generally of making its use more comfortable.
[0008] However, in the cold season and generally when no sensation of hotness is felt, the
use of such aeration systems is unnecessary, even becoming less than comfortable to
the wearer, causing an excessive sensation of coldness and unpleasant draught.
[0009] For this reason, in helmets manufactured according to the known art the aeration
systems are provided with suitable closures, allowing - when required - to open or
close the conveyors implementing ventilation inside the helmet.
[0010] Known closures are generally made by means of shutter-like systems, which can be
actuated by acting with the hands on a given position, usually on the top portion
of the cap.
[0011] However, for obvious reasons said position on which it is necessary to act in order
to control the shutters or the other known closure means, is not visible to the helmet
wearer, who therefore has to search for it by touch, roughly recalling its location.
[0012] Hence, a first problem entailed by known-art helmets is related to the difficulty
in singling out the exact spot on which to act in order to control the closures of
the aeration means, since, very frequently, in sporting practices envisaging helmet
use it is commonly recommended also the use of thick gloves, which limit the sense
of touch.
[0013] However, an even more relevant problem concerns the difficulty, if not the impossibility,
to understand whether the aeration ducts be open or closed.
[0014] It has to be understood that the ducts anyhow allow very limited air flow rates,
as they must have very limited dimensions; this is so since with the increase of the
latter, other dimensions being equal, helmet resistance to knocks decreases.
[0015] Hence, the cool relief effect that these ducts may produce is quite limited and cannot
be immediately felt by the wearer, who therefore is never certain about the aeration
system being open.
[0016] Alike remarks are valid for the closure, since when outside temperature is harsh
it is not always easy to tell whether the sensation of coldness is due to the aeration
ducts being open or to the normal passage of air taking place from the neck and visor.
[0017] Hence, the technical problem underlying the present invention is to provide a helmet
allowing to overcome the drawbacks mentioned above with reference to the known art.
[0018] Such a problem is solved by a helmet according to claim 1.
[0019] The present invention provides several relevant advantages. The main advantage lies
in that the helmet according to the present invention allows to actuate the aeration
system very simply, with no need to search for levers, shutters or other specific
spots or mechanisms on the helmet.
[0020] Moreover, the helmet according to the present invention allows the wearer to easily
realize the position, open or closed, of the aeration means, leaving no doubt about
it.
[0021] Other advantages, features and the operation modes of the present invention will
be made evident from the following detailed description of some embodiments thereof,
given by way of example and not for limitative purposes. Reference will be made to
the figures of the annexed drawings, wherein:
figure 1 is an exploded perspective view of a helmet according to the present invention;
figure 2 is a partially sectional perspective view, showing the helmet of figure 1
with related aeration means in an open configuration;
figures 3A and 3B are two perspective views illustrating the operation of the helmet
according to the present invention, in the open configuration of figure 2 and in a
closed configuration, respectively.
[0022] Referring initially to figure 1, a helmet 100 comprises a cap 1, a visor 2 and a
sealing member 3.
[0023] In particular, in the present embodiment, the helmet is of a jet type; i.e., the
cap 1 covers the head, down to the ears and cheeks, yet leaving face and chin free.
[0024] The visor 2, hinged onto the cap 1 by means of suitable hinges 11, is positioned
to cover the face.
[0025] Analogously to what happens for the helmets manufactured according to the known art,
the visor may be removable from the cap, so as to allow its replacing following scratches
or other damages.
[0026] The hinges 11 implement a pivotable connection of the visor 2, allowing the latter
to be positioned covering the wearer's face, and optionally, depending on its dimensions,
also the cheeks and jaw, or raised, above a top portion 12 of the cap 1.
[0027] This latter configuration allows to wear the helmet, as well as passage of air on
the face in hot seasons or when traveling at a low speed.
[0028] The sealing member 3 is positioned at an edge 13 of the cap, in correspondence of
the opening that the latter has for the face; the former substantially allows to prevent
passage of air inside the helmet when the visor is in a lowered position, covering
the face.
[0029] The sealing member is made by means of a shaped support 3 and it comprises, fastened
to respective ends, two closure thin plates 32 of a soft material, like, e.g., plastics,
providing the required tightness (seal) between cap and visor.
[0030] Therefore, referring to figure 2, the helmet further comprises aeration means 14,
comprising ducts allowing air flow inside the helmet and, anyhow, essentially manufactured
according to the known art.
[0031] The aeration means 14 comprises an inlet section 15, illustrated in detail in figure
1, allowing inletting of outside air into the aeration means and, in particular, into
the ducts.
[0032] Hence, referring to figures 3A and 3B, the visor 2 may be positioned to protect the
wearer's face according to two different configurations; a first one, in which passage
of air inside the inlet sections 15 is prevented, and a second one in which said passage
is allowed.
[0033] Figure 3A depicts the visor positioned so as to cover the inlet sections 15, i.e.
to close the aeration means 14.
[0034] To implement the closure of the aeration means, the visor comprises a portion 21
that, even when arranged to cover the face, extends over the cap, beyond the edge
13.
[0035] Thus, thanks to the use of the sealing member 3, and in particular of the closure
thin plates 31 that keep into contact with the portion 21, passage of air inside the
helmet through the edge 13is not allowed when the visor is in said position.
[0036] Moreover, the portion 21, optionally by means of suitable extensions 22, covers the
inlet sections 15, whose closing is fostered also thereat by means of the sealing
member 3, which comprises, above the same sections, one of the two closure thin plates
31.
[0037] Said extensions 22, which may be used to more effectively implement the closing of
the aeration means, have a shape complementary to the inlet sections 15, so as to
obstruct the latter in the closing position of the aeration means.
[0038] Then, referring to figure 3B, the visor may be positioned, always covering the face,
in a second configuration, in which the inlet sections 15 are not obstructed, so as
to allow passage of air inside the aeration means 14.
[0039] With respect to the preceding case, the visor is lowered even more on the face, toward
the chin, by means of the rotation effected by the hinges 11.
[0040] Therefore, by means of the hinges 11 it is possible to fully raise the visor, in
order to wear the helmet, as well as to alternatively bring said visor to the two
aforedescribed positions, in both of which the visor covers the face.
[0041] To facilitate the positioning of the visor, the hinges 11 may be provided with a
suitable blocking system which, upon reaching each of said positions, allows to at
least partially block the travel of the visor. Then, to reach the next position it
suffices to act on the visor with a force such as to overcome the blocking action.
[0042] Such a system may, e.g., be made by means of the use of suitable seats, positioned
at each of said operative positions, which may accommodate a tooth integral to the
visor motion.
[0043] Therefore, the tooth will remain blocked into the seat, until a force sufficing to
forcedly drive it out therefrom is exerted.
[0044] Anyhow, the helmets manufactured according to the known art are provided with analogous
systems, though envisaging the sole open-visor and closed-visor positions; therefore
the blocking system will not be described in greater detail, as it lies within the
reach of a person skilled in the art.
[0045] Thanks to such a blocking system and to the use of the visor for controlling the
aeration means, it is possible to control the latter very simply, since, by bringing
the visor to the position of maximum rotation toward the bottom portion of the head,
the inlet sections 15 allow passage of air inside the aeration means, as illustrated
in figure 3B.
[0046] Moreover, referring to figure 3A, in the immediately successive position, which may
easily be reached by rotating the visor to the successive blocking spot, said passage
is forbidden.
[0047] Analogously, when wearing-on the helmet with the visor fully raised, the latter could
be lowered until covering the ports, or leaving them free, depending on whether it
is desirable to keep the aeration means closed or open, respectively,.
[0048] Moreover, it is understood that the sealing member 3 may also have different shapes,
since on the one hand its object is to avoid passage of air inside the helmet through
the edge 13, both when the aeration means is open and when it is closed.
[0049] On the other hand, the sealing member allows to avoid inletting of air inside the
aeration means, when the inlet sections are closed.
[0050] Therefore, also different configurations of the sealing member may be used, e.g.
by fastening of the closure thin plates onto the visor itself, or optionally by using
more than one member, e.g. two distinct ones for inlet sections and edge 13 of the
cap.
[0051] According to a different embodiment, not illustrated in the figure, the helmet may
be of integral type, covering mouth and jaw as well; in that case, the visor will
prevent passage of air both through the edge 13 and at the mouth-covering cap portion.
[0052] In this case, the helmet could have inlet sections of the aeration means both at
the wearer's mouth and forehead, and the visor will allow to obstruct, or leave open,
both ports with the same motion.
[0053] Evidently, in this case the visor 2 will have a different shape in order to operate
concomitantly on both inlet sections.
[0054] E.g., besides the extensions 22, ports might also be present, not illustrated in
figure, operating at the mouth-covering cap portion.
[0055] Said configurations are not described in detail, as they are within the reach of
a person skilled in the art.
[0056] Lastly, it is understood that anyhow the actuation of the aeration means may be controlled
also with different motions of the visor.
[0057] E.g., the opening and closing positions could be reversed, i.e. a lowering of the
visor would cause the closing of the inlet sections, contrarily to the preceding case.
[0058] Such a configuration is attainable by utilizing, instead of the extensions 22, ports,
which therefore act inversely with respect to the aforedescribed embodiment.
[0059] In greater detail, passage of air in the inlet sections 15 is prevented when the
visor is completely lowered, as the ports are not aligned with the sections 15, whereas
in the successive position such an alignment is made, and therefore the aeration means
is not obstructed.
