BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present patent application for industrial invention
relates to an upper for shoes with perforated sole to be mounted on
ventilated or perspirating bottoms molded from plastic
materials.
[0007] The scope of the present invention also comprises the shoe
provided with said upper.
[0008] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
[0009] The peculiarities and advantages of the present invention
will be clearer following to a brief description of the state of
the art.
[0010] For a long time now the market has offered boots of
different heights formed of a leather or plastic upper mounted,
with the interposition of a sole that closes it in lower position,
on a bottom mostly made of rubber or equivalent plastic
materials.
[0011] More recently shoes provided with ventilated bottoms have
appeared on the market, with the advantage of providing air
exchange to the user's feet.
[0012] In order to ensure such a functionality said bottoms are
normally provided with compressible pads that are actually
capable--being subject to the pressure discharged on them at every
step by the front of the foot--of generating a pumping effect to
extract the air contained in the upper and convey it outside the
shoe by means of a non-return vent valve.
[0013] Moreover, other models of shoes are known, being provided
with a bottom with shock-absorbing properties, in association or
not with said ventilating properties, in order to exert an
advantageous anti-shock function in favor of the users feet.
[0014] Finally, sonic models of shoes are provided with a bottom
with perspirating properties, which is able to ensure a fresh air
flow towards the front of the foot, and also capable of preventing
water on the ground from rising again inside the shoe.
BRIEF SUMMARY OF THE INVENTION
[0015] Starting from such a state of the art, the specific purpose
of the present invention is to devise an upper for shoes molded
from plastic materials that allows the shoe provided with it to
acquire advantageous ventilating or perspirating properties.
[0016] Another purpose of the present invention is to allow the
shoe provided with the upper of the invention to acquire said
ventilating or perspirating properties with great structural
simplicity, easy assembly and limited cost.
[0017] First of all, it must be noted that the new upper that
achieves said purposes is configured as a "monolithic body" made of
rubber of thermoplastic materials.
[0018] Such a body incorporates both a perimeter section with
vertical development designed to "embrace" the user's foot (that it
to say the upper) and the sole that is the horizontal surface where
the user's foot lies.
[0019] The main peculiarity of the invention is that the sole of
said "monolithic body" is provided with through openings for air
passage from inside outside and vice versa.
[0020] In such a way the upper of the invention can be mounted on a
corresponding bottom for shoes, possibly a molded one, of the type
provided with ventilating or perspirating properties.
[0021] The benefits generated by said bottoms, in terms of
ventilation or perspiration for the user's foot, can be experienced
inside the monolithic upper. This is because the sole incorporate
in said monolithic upper is provided with through openings that do
not interfere With air circulation between upper and bottom.
[0022] When the upper of the invention is mounted on a ventilating
bottom, said openings of the sole are crossed by "forced" air jets
coming from the bottom.
[0023] As it is known, this type of bottoms is capable of
generating, when they are compressed by the weight of the users
foot discharged on it during walking, a pump-effect capable of
favoring the extraction of atmospheric air (from the outside of the
same bon and the energetic transfer of air upwards, that is to say
towards the upper.
[0024] When the same upper is mounted on a perspirating bottom.
said openings of the sole prevent interference with the "natural"
air exchange between bottom and upper that is desired inside the
shoe.
[0025] In particular, said perspirating bottoms of known type are
provided on the front of the foot with holes across the entire
thickness that are internally closed by membranes made of materials
of known type that are capable of interfering with the ii sing of
water from the ground, but not with air passage.

DETAILED DESCRIPTION OF THE INVENTION
[0032] Referring to FIG. 1, the upper of the invention (1) has a
monolithic structure obtained by molding, rubber or thermoplastic
materials, of which the sole (1 a) is an integral part.
[0033] The front of the sole (1a) is provided with openings that
consist in transversal rows of through holes (1b) ending inside the
upper (1), as shown in FIG. 1 A.
[0034] In the embodiment of FIG. 1 B, the openings of the sole (1a)
consist in a large window (10b) covered with a corresponding piece
of air-permeable fabric (11 b).
[0035] Moreover, it must be noted that the, according, to the
preferred embodiment for boots shown in FIGS. 1, 1 A, and 1 B, the
upper (1) incorporates in correspondence with one or both sides, at
the malleolus height, vertical bands (1c) made with elasticated
fabric.
[0036] Inside the upper (1) an ordinary hygienic insole (3) that is
permeable to air is preferably mounted.
[0037] The latter is made with air-permeable material or material
that is not intrinsically air-permeable, but provided with through
holes obtained in corresponding positions to the openings (1b, 10b)
of said sole (1a).
[0038] Moreover, such an upper (1) can be mounted on bottoms molded
from rubber or thermoplastic materials, of known type, provided
with ventilating or perspirating properties.
[0039] In such a case, the openings (1b, 10b) provided, on the sole
(1a) generate an advantageous, either forced or not, air exchange
between the bottom (2) and the inside of the upper (1).
[0040] Moreover, it must be noted that the present invention
provides that the upper (1) preferably cooperates with a specific
ventilating shock-absorbing bottom of new design (2), which is
shown in FIGS. 2 and 3.
[0041] To that end it must be noted that also this specific bottom
(2) is obtained from molding rubber or thermoplastic materials.
[0042] The top of said bottom (2) is hollow and provided with a
sort of tub, which comprises a first chamber (C1) situated in the
front of the foot and a second chamber (C2) situated inside the
heel.
[0043] From the bottom of the two chambers (C1, C2) corresponding
series of vertical partitions (2b, 2c) protrude, being arranged in
multiple transversal rows.
[0044] In particular, the partitions (2b) housed inside the first
chamber (C1) are elastically deformable; moreover, in order to
increase flexibility, they preferably have a saw-toothed
profile.
[0045] Moreover, the tub of said bottom (2) is associated with a
non-return vent valve (4) inserted in the transversal edge of the
heel.
[0046] When the upper of the invention (1) is coupled with the
bottom (2), the sole (1a) of the upper (1) closes the two chambers
(C1, C2) from the top, lying on the vertical partitions (2b,
2c).
[0047] In such a condition the through holes (1b) provided in the
front of the sole (1a) are arranged in correspondence with the
first chamber (C1) from which said flexible partitions (2b)
protrude upwards.
[0048] It is important to say that the permanent fixing between the
upper of the invention (1) and the bottom (2) can be obtained in a
very practical and quick way, also in view of the fact that said
parts are made with the same materials.
[0049] In particular, such an operation can be made by gluing or
heat sealing, without requiring the long burdensome sewing
operations that are typical of most traditional shoes.
[0050] To that end the bottom (2) is surrounded, by a flat
perimeter border (2a) on which the sole (1 a) of the upper (1) lies
perimetrally; it being provided that the stable coupling of the two
components (1, 2) is obtained on the perimeter border (2a) by means
of gluing or heat sealing.
[0051] Still referring to the aforementioned figures, the use and
operation modes of the shoe obtained by coupling the upper of the
invention (1) and the corresponding ventilated bottom (2) will be
illustrated.
[0052] As soon as the user of a similar shoe (S) starts walking,
the advantageous ventilation effect is produced in favor of the
upper (1).
[0053] In particular, every time the shoe (S) lies on the ground,
the weight of the user generates the compression of said deformable
partitions (2b) provided inside the first chamber (C1) of the
bottom (2).
[0054] Said compression of the deformable partitions (2b) allows
for height reduction of the section of said first chamber (C1) that
contains them and consequently for compression of the air contained
inside it.
[0055] In such a condition air tends to flow outside the bottom (1)
through said non-return vent valve (4).
[0056] Instead, during the aerial phase of every step, because of
the absence of pressure exerted by the user's weight, the
deformable partitions (2b) spontaneously take an erected position
and the chamber (C1) containing those resumes its "natural" height
and consequently its original volume.
[0057] A further consequence of the new expansion of the first
chamber (C1) of the bottom (2) is to recall the air contained in
the upper (1) through the holes (1b) obtained in the front of the
sole (1a).
[0058] It is worthless saying that the following compressions and
expansions of said chamber (C1) of the bottom (2) are sufficient to
generate a continuous air exchange inside the upper of the
invention (1), thus considerably increasing comfort of the foot
contained in the shoe (S) provided with it.
[0059] Finally, it must be noted that, although in the enclosed
figures the upper of the invention (1) has the structure of a
typical upper for a boot, the same can be given any other
configuration alternatively designed for high or low shoes, laced
or not laced shoes, women's or men's shoes.
