Description
BACKGROUND OF THE INVENTION
[0001] Among the many motorcycling sports activities, practice of
the discipline known as supermotard is increasingly widespread; in
this discipline, motorcycles that have a particular structure are
used on appropriately provided dirt tracks, generally constituted
by two parallel straight sections connected by two sharp
U-bends.
[0002] The riding technique used in supermotard competitions and in
non-competitive practice entails that the rider rides the
dirt-track bends by placing one or both of his feet on the ground
in order to ensure that the motorcycle, which moves along the
entire bend by countersteering, has the required stability.
[0003] The application of this riding technique entails intense
wear of the sole of the shoes worn by the rider; however, this wear
is concentrated almost entirely in the outer region of the sole of
the foot.
[0004] Likewise, steering techniques used for the motorcycling
discipline of motocross cause a particularly intense wear of the
sole in very specific points, which however in this case affect the
inner region of the sole and are caused mainly by the action of the
gear lever and of the rear break.
[0005] Known sports shoes, intended for the practice of supermotard
or motocross, are currently used which have a sole that is made of
a rubber that has high-level mechanical properties and wear
resistance, and are capable of withstanding the stresses imparted
by their use on the track for a certain period of use.
[0006] The main drawback of this known type of sports shoe is that
the rubber used to provide the sole is very expensive, due to the
materials used for its manufacture, to the production process that
is followed and to the specific nature of the application.
[0007] Another drawback of these shoes of the known type relates to
the fact that due to their particular use, which entails wear that
is concentrated almost entirely in the outer region of the sole of
the foot, they are unusable when said region has worn out, even
though the remaining part of the sole and of the upper are still in
excellent conditions.
[0008] Moreover, low-cost sports shoes for supermotard are known in
which the sole is made of a rubber that has low-level mechanical
and wear-resistance properties and on which it is possible to
arrange, in the region of higher wear, detachable outsoles made of
a rubber that has higher mechanical and wear-resistance
properties.
[0009] Said outsoles are connected to the sole by means of one or
more screws, which are arranged vertically with their head directed
downward, so as to grip in a lower region the sole of the shoe and
allow to replace said outsoles once they are worn.
[0010] The main drawback of this known type of shoe is that as a
consequence of the wear of the outsoles, the heads of the screws
that couple said outsoles to the sole make contact with the ground
and are severely damaged by friction against it, to the point that
removing and replacing them is extremely difficult if not
impossible.
[0011] Another drawback of this known type of shoe is that if
outsole replacement is possible, it requires the use of new screws
for fixing to the sole, and this causes an increase in costs and in
the number of components used.
[0012] Low-cost shoes for motocross are also known in which the
sole is made of a rubber that has low-level mechanical and
wear-resistance properties and on which it is possible to arrange,
in the regions of higher wear, removable outsoles made of a rubber
that has higher mechanical and wear-resistance properties.
[0013] Said outsoles are coupled to the sole by interposing a layer
of adhesive that is capable of generating a high adhesion force, in
order to withstand the intense stresses to which the outsole is
subjected during use.
[0014] The main drawback of this known type of shoe is that the
outsoles can be replaced only by using appropriately provided
equipment that is suitable to overcome the adhesion force of the
adhesive and is available for example at the facility used to
manufacture said shoe, and manual replacement of the outsole by the
user is impossible.
SUMMARY OF THE INVENTION
[0015] The aim of the present invention is to solve the
above-described problems, eliminating the drawbacks of the cited
background art, by providing a sports shoe, particularly for
motorcycling and particularly for the sports practice of
supermotard or motocross, that allows an extended use thereof that
entails intense wear of the sole concentrated in certain points
thereof.
[0016] Within this aim, an object of the invention is to provide a
sports shoe whose technical characteristics can be restored rapidly
and simply and at low cost and in a short time.
[0017] Another object is to provide a sports shoe that is
structurally simple and has low manufacturing costs.
[0018] This aim and these and other objects that will become better
apparent hereinafter are achieved by a sports shoe particularly for
motorcycling, comprising an upper with which a sole is associated,
characterized in that at least one receptacle is provided on said
sole, at least at the outer region of the sole of the foot, for
detachably accommodating one or more outsoles that are thicker than
said at least one receptacle, said sole and said one or more
outsoles being detachably associable by way of connecting means
constituted by layers of temporary dry grip material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0038] As the persons skilled in the art would readily understand,
in the embodiments that follow, individual characteristics, given
in relation to specific examples, may actually be interchanged with
other different characteristics that exist in other
embodiments.
[0039] With reference to the figures, the reference numeral 1
designates a sports shoe, used for motorcycling and particularly
for the discipline of supermotard, which is composed of an upper 2
that is associated with a sole 3 in an upper region.
[0040] A first receptacle 4 and a second receptacle 5 are formed in
the sole 3, to be located at the outer perimetral region of the
plantar surface of the foot of a user, at the bottom surface 3a of
the sole 3, which is made of a rubber that has low-level mechanical
and wear-resistance properties and is therefore very cheap; said
receptacles are preferably provided at the metatarsal and heel
regions, respectively.
[0041] Said first and second receptacles lie transversely along
approximately half of the width of the sole 3, approximately
starting from the center zone of said sole, until they affect or
extend over the perimetric edge 6 of the sole 3; each one of said
first and second receptacles affects or extends in part of the
height of the sole 3.
[0042] The first receptacle 4, arranged toward the front, lies
longitudinally between the tip region 7 of the sole 3 and the arch
region 8, and is substantially rectangular (i.e. looks to a great
extent as a rectangle), so as to occupy approximately the outer
half of the sole in the metatarsal region.
[0043] The second receptacle 5, arranged toward the rear, is
likewise substantially rectangular, occupies approximately the
outer half of the heel 9 of the sole 3, and also affects or extends
over the rear part of the perimetric edge 6 of said sole.
[0044] The first and second receptacles 4 and 5 respectively have a
first preferably flat bottom 10 and a second preferably flat bottom
11, on which a first layer 12 of temporary dry grip material and a
second layer 13 of temporary dry grip material are respectively
coupled.
[0045] The first and second layers 12 and 13 may be provided for
example by means of a film of the temporary dry grip material with
complemental parts that adhere to each other when pressed together
and are further separable when pulled apart, known by the
trade-name Velcro.
[0046] The sports shoe 1 according to the invention further
comprises a first outsole 14, which is substantially shaped like a
parallelepiped and whose cross-section duplicates the cross-section
of the first receptacle 4, so that it can be inserted detachably
therein.
[0047] The first outsole 14, conveniently made of a rubber that has
better mechanical and wear-resistance characteristics than the
rubber that constitutes the sole 3, is higher or has a thickness
equal to and/or greater than the first receptacle 4 is deep or
thick, so that when it is accommodated in said first receptacle a
first lower face 15 thereof protrudes from said receptacle by a
chosen extent.
[0048] A second upper face 16 of said first outsole has a shape
that duplicates the shape of the first bottom 10 of the first
receptacle 4, so as to be able to mate with it.
[0049] Moreover, a third layer 17 of temporary dry grip material
with complemental parts that adhere to each other when pressed
together and are further separable when pulled apart, such as the
hook and loop-type fasteners, known for example by the trade-name
(trademark) Velcro, is further applied in an upper region of the
second face 16 and is suitable to adhere to the first layer 12,
providing a stable but nonetheless detachable coupling between the
first outsole 14 and the sole 3.
[0050] A second outsole 18, also substantially shaped like a
parallelepiped, has a cross-section that duplicates the
cross-section of the second receptacle 5 formed in the heel 9 of
the sole 3, so that it can be accommodated detachably therein.
[0051] The second outsole 18 also is conveniently made of a rubber
whose characteristics are similar to those of the first outsole 14
and is higher or thicker than the second receptacle 5 is deep or
thick, so that when it is accommodated in said second receptacle a
third lower face 19 thereof protrudes from said receptacle by a
chosen extent.
[0052] A fourth upper face 20 of said second outsole has a shape
that duplicates the shape of the second bottom 11 of the second
receptacle 5, so as to be able to mate with it.
[0053] A fourth layer 21 of temporary dry grip material, known for
example by the name Velcro, is further applied in an upper region
of the fourth face 20 and is suitable to adhere to the second layer
13, providing a stable but nonetheless detachable coupling between
the second outsole 18 and the sole 3.
[0054] Said first, second, third and fourth layers of grip material
that constitute the means for mutually connecting the first and
second outsoles and the main sole 3 allow a stable and safe
connection thereof that is at the same time detachable.
[0055] The first and third faces 15 and 19 may further have a
plurality of variously shaped protrusions and/or ridges 30 suitable
to improve the grip of the outsoles on the ground.
[0056] The shoe 1 according to the invention thus provided can
therefore be used advantageously in the discipline of supermotard,
since it provides the rider with safe support in the outer region
of the plantar surface of the foot by way of the high-level
mechanical properties of the material that constitutes the first
and second outsoles.
[0057] Said outsoles, during use of the sports shoe, are firmly
connected to the sole by way of the connecting means described
above and can be detached easily therefrom when their use has
ended, allowing quick replacement of the first and second outsoles
14 and 18, if worn, without the aid of specifically provided
equipment.
[0058] FIGS. 6 to 8 illustrate a second embodiment 101 of the
sports shoe according to the invention, which differs from the
first embodiment described above in that below its sole 103 there
is a single third receptacle 122, which is generally as wide as
half the sole 103 and lies, in the outer region thereof, at the
metatarsus, at the arch region of the foot, and at the heel.
[0059] The third receptacle 122, which affects or extends over the
outer part and the rear part of the perimetric edge 106 of the sole
103, is provided with a third bottom 123, on which a fifth layer
124 of grip material, for example of the type known as Velcro, is
applied.
[0060] The sports shoe 101 comprises a third outsole 125, which is
made of a material that is similar to the material that constitutes
the first and second outsoles 14 and 18, is shaped substantially
like a parallelepiped, and has a cross-section that duplicates the
cross-section of the third receptacle 122, so that it can be
inserted therein.
[0061] The third outsole 125 is provided with a fifth upper face
126, on which a sixth layer 127 of grip material, for example of
the type known by the name Velcro, is applied, said material being
suitable to adhere to the fifth layer 124, providing a stable and
in any case detachable coupling between the third outsole 125 and
the sole 103.
[0062] The third outsole 125 is higher than the third receptacle
122 is deep, so that it protrudes partly downward from it.
[0063] A third embodiment 201 of the sports shoe according to the
invention, suitable for practicing the discipline of supermotard,
differs from the ones described previously in that a fourth
receptacle 228, a fifth receptacle 229 and a sixth receptacle 230
are formed below the sole 203 at its outer region, respectively in
the metatarsal region, in the arch region, and in the heel
region.
[0064] Said fourth and fifth receptacles, which have an
approximately rectangular cross-section, affect the perimetric edge
of the sole 203, while the sixth receptacle 230, which also has a
substantially rectangular cross-section, occupies approximately the
outer half of the heel 209, affecting or extending over the
perimetric edge of the sole 203 in its rear region as well.
[0065] Said fourth, fifth and sixth receptacles respectively have a
fourth bottom 231, a fifth bottom 232 and a sixth bottom 233, which
are for example flat and on each of which respective seventh layers
234 of grip material, each constituted for example by a layer of
material known by the trade-name Velcro, is applied.
[0066] The sports shoe 201 further comprises a fourth outsole 235,
a fifth outsole 236 and a sixth outsole 237, whose cross-section
duplicates respectively the fourth, fifth and sixth receptacles;
said outsoles can be inserted in said receptacles, and an eighth
layer 241 of grip material, constituted for example by a layer of
material known by the trade-name Velcro, is applied to the
respective upper sixth face 238, seventh face 239 and eighth face
240 of said outsoles.
[0067] In a manner similar to the first and second embodiments
described above, and also to the following ones, said fourth, fifth
and sixth outsoles are made of a rubber that has high-level
mechanical and wear-resistance characteristics, have a plurality of
variously shaped protrusions and/or ridges 30 for grip enhancing,
and can be accommodated respectively within the fourth, fifth and
sixth receptacles, so that they can be coupled detachably to the
sole 203.
[0068] FIGS. 12 and 13 illustrate a fourth embodiment of the sports
shoe 301 according to the invention, suitable in particular for the
practice of motocross.
[0069] Said fourth embodiment differs from the preceding ones in
that below the sole 303 there is a single seventh receptacle 342,
which extends approximately from the inner metatarsal region 343
towards the outer perimetral region of the plantar surface of the
foot and comprises the entire cross-section of said sole in the
arch region 344 and a step 345 that connects said arch region to
the heel 309 of the sole 303.
[0070] A ninth layer 346 of temporary dry grip material,
constituted for example by a layer of material known as Velcro, is
applied to the bottom of the seventh receptacle 342.
[0071] A seventh outsole 347, made of a material similar to the one
used for the outsoles described earlier and having a shape that
duplicates the shape of the seventh receptacle 342 and a height
that is substantially equal or corresponds to the depth of said
seventh receptacle so that it can be accommodated therein, has, on
a ninth upper face 348, a tenth layer 349 of temporary grip
material, constituted for example by a layer of material known as
Velcro, so that it can be associated detachably with the sole
303.
[0072] A fifth embodiment of the sports shoe 401 according to the
invention, also suitable for motocross, is shown in FIGS. 14 and 15
and differs from the fourth embodiment described above in that the
eighth receptacle 450 formed in a lower region in the sole 403,
runs from the inner metatarsal region 443 up to the arch region
444, without therefore affecting the heel 409.
[0073] An eighth outsole 451, whose shape duplicates the shape of
the eighth receptacle 450, can be inserted therein and can be
coupled detachably by way of the same connection means described
above for the previous embodiments.
[0074] FIG. 11 is a view of a variation 501 that can be applied to
each one of the embodiments described so far and comprises a ninth
outsole 552, which can be accommodated in a ninth receptacle 553
formed below the sole 503 and can be coupled detachably thereto by
means of an eleventh layer of grip material 554 that is applied to
the tenth upper face 555 of the ninth outsole and a twelfth layer
of grip material 556 that is applied to the bottom 557 of the ninth
receptacle 553.
[0075] The ninth outsole 552 is wider than the ninth receptacle
that accommodates it and is provided with a lug 558 that protrudes
upward with respect to it and externally with respect to the ninth
receptacle so as to constitute a lateral protection for said
eleventh and twelfth layers of grip material, also for aesthetic
purposes. It is optionally possible to provide a layer of dry grip
material also at the inner lateral surface of the lug 558, said
layer being capable of adhering to a corresponding layer of dry
grip material provided on at least one portion of the perimetric
edge 6 of the sole, so as to ensure better adhesion of the outsole
to said sole and better adapt to any curves of said sole.
[0076] FIGS. 16 to 18 illustrate a sixth embodiment of the sports
shoe 601 according to the invention, particularly suitable for
motocross, which comprises a box-like main sole 603, which is
preferably obtained by injecting plastic material that has
low-level mechanical and wear-resistance properties and is
therefore very cheap.
[0077] A tenth receptacle 659 is formed below the sole 603 and runs
from the heel region to the metatarsal region and affects or
extends over the arch region, particularly the inner lateral region
of the foot.
[0078] A thirteenth layer of temporary dry grip material 660,
constituted for example by a layer of material known by the
trade-name Velcro, is applied to the bottom of the tenth receptacle
659.
[0079] A tenth outsole 661, which is made of a material similar to
the one used for the outsoles described earlier, is shaped
complementarily with respect to the tenth receptacle 659, and is
higher, along most of its extension, than said receptacle is deep,
so that it can be accommodated therein, has, on an eleventh upper
face 662 thereof, a fourteenth layer 663 of temporary grip
material, constituted for example by a layer of material known by
the trade-name Velcro, so that it can be detachably associated with
the corresponding layer on the sole 603.
[0080] In order to further ensure detachable locking of the tenth
outsole within the tenth receptacle during use, said tenth outsole
may conveniently have, along a portion located proximate to its
front edge 664, a height that is approximately equal to the height
of the tenth receptacle, so as to reduce the possibility of being
accidentally dislodged during use for example due to the air stream
that affects it.
[0081] The variation 501 described above and shown in FIG. 11 may
obviously be applied also to the sixth embodiment 601 of the sports
shoe.
[0082] In order to contain manufacturing costs, it is
advantageously possible to provide identical receptacles on soles
of different sizes, so as to require a reduced number of outsoles,
each of which can be applied to a preset range of shoe sizes.
[0083] It has thus been found that the invention has achieved the
intended aim and objects, a sports shoe particularly for
motorcycling having been provided which allows extended use thereof
even if riding techniques such as the one commonly used in the
discipline of supermotard, which entail intense wear of the sole
concentrated in certain points thereof, are used.
[0084] Another important object that has been achieved is to
provide a sports shoe that by comprising parts that are subjected
to wear allows easy and quick replacement thereof.
[0085] The materials used, as well as the dimensions that
constitute the individual components of the invention, may of
course be more pertinent according to specific requirements.
[0086] The various means for performing certain different functions
need not certainly coexist only in the illustrated embodiment that
are not intended to be limitative for the claimed invention but can
be present per se in different embodiments, including ones that are
not illustrated and which are covered by the terms of the appended
claims.
[0087] The characteristics described as advantageous, convenient or
the like may also be omitted or be replaced with equivalents.
[0088] In a variation, it is possible to associate below the sole,
along part or all of its surface, one or more outsoles by way of
connecting means constituted by a layer of temporary dry grip
material.
[0089] Said layers of temporary dry grip material may be each
constituted by a layer of the material known as Velcro, applied
respectively to the upper face of said one or more outsoles and to
the opposite lower face of the sole.
