[0001] The invention concerns a footwear item of the improved type, structured in such a
way as to make it possible to drastically reduce its complexity and the number of
steps necessary for its production.
[0002] The invention concerns also the method for making said improved footwear item.
[0003] It is known that up to date the various methods used for making footwear consist
of a considerable number of steps, some of which, furthermore, are characterized by
a high degree of complexity.
[0004] In this context, the term footwear means any type of object intended to protect the
foot, of the type comprising a sole kept in position by an upper.
[0005] In greater detail, said production methods usually comprise a first step in which
a designer drafts on paper a first sketch illustrating an idea for a footwear item.
Said idea is successively transferred on prototypes, usually made of a plastic material,
in such a way as to simulate the three-dimensional shape that the footwear item will
assume.
[0006] In a successive step, the prototypes in turn make it possible to define on a plane
the various patterns, typically made of cardboard, which represent the individual
portions made of leather or another material that, joined together, will form the
actual upper of the footwear item.
[0007] In this regard, in the case where the footwear items are handmade, said patterns
are positioned on large pieces of leather, or another material, in such a way that
they serve as a guide for cutting said individual leather portions that will make
up the upper. In the case where, instead, said leather portions are press-cut by means
of automatic or semi-automatic devices, like for example presses, it is necessary
to produce special dies having the same shape as said cardboard patterns.
[0008] Once the plurality of portions in leather or another material have been produced,
they are joined to one another on a three-dimensional template that substantially
reproduces the shape of a foot, in such a way as to obtain said upper. This operation,
which has the purpose to simplify the assembly of the upper, is defined "upper pre-forming
operation" in technical jargon.
[0009] The upper obtained by proceeding as described above is successively connected to
a sole and is optionally equipped with some accessories like, for example, laces,
Velcro straps or zip fasteners, in such a way as to make it easier for a user to put
on the shoe.
[0010] Said methods for making footwear of the known art, however, pose some recognized
drawbacks that are described here below.
[0011] A first drawback posed by said methods is represented by the need to perform all
the steps mentioned above for each footwear model and for each size of each model.
In particular, it is necessary to carry out the steps of preparing the cardboard patterns,
cutting the leather portions using said patterns and joining the various parts in
order to obtain the upper.
[0012] To disadvantage, the considerable amount of time necessary to implement said methods
of the known art and the corresponding difficulty in the execution are evident. Furthermore,
in the case where the leather portions that will constitute the upper are press-cut
by means of a press, to disadvantage it is necessary to be able to use a plurality
of dies for each single type of footwear and for each size of each type of footwear.
[0013] Furthermore, another drawback posed by the known art lies in that the step of cutting
or press-cutting the portions in leather or another material produces scraps that,
to disadvantage, will affect the final cost of the footwear item, both because part
of the purchased material is not used and because said scraps must be disposed of.
[0014] The present invention intends to overcome all of the drawbacks mentioned above.
[0015] In particular, it is the object of the invention to provide a footwear item structured
in such a way as to make it possible to drastically reduce the steps required for
its production.
[0016] It is another object of the invention to provide a footwear item structured in such
a way as to allow the reduction, if not the elimination, of the waste material produced
during its production steps.
[0017] Consequently, to advantage, in the definition of the final cost of the shoe it is
no more necessary to consider the costs due to the production and disposal of scraps,
with consequent economic advantages.
[0018] It is a further object of the invention to provide a footwear item structured in
such a way as to allow the reduction, if not the elimination, of the production steps
that require human labour. Consequently, it is the object of the invention to provide
a footwear item structured in such a way that it can be produced in series while at
the same time guaranteeing a high degree of uniformity among the items produced in
the same production lot.
[0019] It is another, yet not the least object of the invention to provide a footwear item
structured in such a way as to allow the external appearance of the same to be modified
with a simple procedure and substantially at no cost.
[0020] For example, the document
US 1902780 discloses a method for manufacturing a component of a footwear item and the relevant
footwear item by means of knitting.
[0021] The objects described above are achieved by providing a footwear item according to
the independent claim 1 and by a method according to the independent claim 6.
In particular, the footwear item that is the subject of the invention is characterized
in that the upper is obtained from a fabric element made as a single piece through
a weaving process. In this fabric element, in particular, it is possible to identify
at least three areas that are adjacent to one another and, at least at the level of
joining sections between the first area and the second area and between the second
area and the third area, it features a type of stitch pattern according to which the
stitches located at the centre are tucked with respect to the lateral stitches. This
type of stitch pattern makes it possible to give a three-dimensional shape to the
same fabric element, with a parabolic outline according to the direction defined by
its longitudinal axis.
In this context, the term "stitch" means any loop pulled through between the weft
yarn and the warp yarns in order to join them.
In particular, any row that makes up a woven fabric, called "rank" in technical jargon,
is constituted by a single weft yarn that is pulled through the warp yarns more than
once, moving from one side of the loom to the other in such a way as to define a plurality
of said stitches. In said stitch pattern with tuck stitches, the insertion of the
weft yarn is skipped at the level of predefined warp yarns along the same row. In
this way, a row in which said stitch pattern with tuck stitches has been created will
have a smaller number of stitches than a row in which the weft yarn has been pulled
through all of the warp yarns.
[0022] Further characteristics of the footwear item that is the subject of the invention
are disclosed in the dependent claims.
[0023] In particular, to advantage, the fact that the fabric element that constitutes the
upper of the footwear item of the invention is made with an elastic yarn, as expressed
in claim 5, on one side makes it easier for a user to put on said footwear item even
in the absence of laces, zip fasteners or Velcro straps, and on the other side to
improve the wearability of the shoe itself as the upper can adhere and properly adapt
to the size of the person's leg.
[0024] Furthermore, still to advantage, the use of a fabric element improves the breathability
of the footwear item.
[0025] Preferably, but not necessarily, said elastic yarn comprises the product known as
Elastam in a percentage that ranges between 2% and 10%. It cannot be excluded, however,
that Elastam may also be used in different percentages or that different elastic materials
may be used instead of Elastam.
[0026] The invention also includes the method for making the footwear item of the invention.
[0027] Said objects, together with the advantages that are described here below, will be
highlighted in the description of a preferred embodiment of the invention that is
provided by way of non-limiting example with reference to the attached drawings, wherein:
- Figure 1 shows an axonometric view of the footwear item that is the subject of the
invention;
- Figure 2 shows an axonometric view of the fabric element belonging to the footwear
item of the invention;
- Figure 3 shows a front view of the fabric element belonging to the footwear item of
the invention;
- Figure 4 shows a side view of the fabric element belonging to the footwear item of
the invention;
- Figure 5 shows the side view of the fabric element represented in Figures 2, 3 and
4, folded on itself at the level of its longitudinal axis X;
- Figures 6 and 7 respectively show a rear axonometric view and a front axonometric
view of the upper belonging to the footwear item of the invention;
- Figure 8 shows an exploded axonometric view of the components that make up the footwear
item of the invention illustrated in Figure 1.
[0028] The improved footwear item of the invention is represented as a whole in Figure 1,
where it is indicated by
1.
[0029] As shown in Figure 1, said footwear item
1 comprises a sole
2 that allows it to rest on an underlying surface, and an upper
3 defining an inner space suited to accommodate and hold a person's foot. The upper
3 is connected to said sole
2 by means of known techniques and elements, for example by sewing or glueing. As can
be observed in Figure 1, according to the preferred embodiment described herein the
footwear item
1 is a boot. It cannot be excluded, however, that in different embodiments of the invention
said footwear item
1 may be of a different type, for example a sports shoe, a moccasin, etc., which can
be obtained by conveniently modifying the dimensions of the elements that make it
up.
[0030] According to the invention, in the footwear item
1 the upper
3 comprises and is obtained by means of a fabric element
4 shown in Figures from 2 to 4, created as a single piece through a weaving process
and successively folded on itself in such a way as to connect its two longitudinal
sides
43 and
44. In particular, said fabric element
4 defines three areas
51, 52 and
53 that are adjacent to one another along the direction defined by its longitudinal
axis
X. The first area
51 is suited to at least partially enclose the leg of a person, as shown in Figure 1,
the second area
52 is suited to enclose the tarsal part of the person's foot and the third area
53 is suited to enclose the metatarsal part of the foot when the same footwear item
1 is worn by said person.
[0031] As shown in Figure 3, the fabric element
4, at least at the level of joining sections
61 and
62 that are respectively located between the first area
51 and the second area
52 and between the second area
52 and the third area
53, features a stitch pattern according to which, for each row of said sections
61 and
62, the stitches
7 located at the centre are tucked with respect to the lateral stitches
8, in such a way as to give said fabric element
4 a three-dimensional shape with parabolic outline according to the direction defined
by its longitudinal axis
X. Said parabolic outline can be clearly observed in Figure 4.
[0032] Thus, to advantage, the fabric element
4 obtained in this way develops according to an outline that substantially reproduces
that of the tarsal area of the foot of the person who will wear the footwear item
1 of the invention, with no need to carry out further processing steps to form the
upper, differently from that which is envisaged by the methods for making footwear
items of the known art.
[0033] In embodiments of the footwear item
1 of the invention that represent an alternative to the preferred embodiment described
herein, further one or more sections may be provided, interposed between said two
joining sections
61 and
62 and featuring said stitch pattern with central tuck stitches
7. Advantageously, the higher the number of sections featuring said stitch pattern,
the more rounded the substantially parabolic outline of the fabric element
4.
[0034] The number of central stitches
7 that are tucked with respect to the lateral stitches
8, for each one of said joining sections
61 and
62, increases progressively according to an advance direction indicated by the arrow
V in Figures from 2 to 4, as defined by the same longitudinal axis
X. In other words, for example, in said type of stitch pattern only the central stitch
71 passing through the longitudinal axis
X may initially be tucked, and successively also the stitches adjacent to said central
stitch
71 after a given number of rows, and then other stitches adjacent to the previous tuck
stitches, and so on until the number of tuck stitches substantially corresponds to
the number of stitches that can be made in one row. Said sections
61 and
62 featuring said stitch pattern will develop following diverging directions, as shown
in Figures 2 and 3.
After the sections
61 and
62 featuring said tuck stitch pattern, the fabric element
4 respectively includes said second and third area
52 and
53, in which all of the stitches of each row are carried out correctly.
Advantageously, therefore, the alternance between said three areas
51, 52 and
53 and said joining sections
61 and
62 makes it possible to obtain said parabolic outline of the fabric element
4, as shown in Figure 4.
[0035] As shown in Figure 3, according to the preferred embodiment of the invention described
herein, in the footwear item 1 of the invention the fabric element
4 has a symmetrical outline with respect to its longitudinal axis
X.
[0036] In this way, to advantage, as will be explained in greater detail below during the
description of the method for making the footwear item
1 of the invention, there will be a perfect superimposition of the two symmetrical
halves
41 and
42 of the fabric element
4 and of the corresponding longitudinal sides
43 and
44. It cannot be excluded, however, that in different embodiments of the invention said
fabric element
4 may have an asymmetrical profile.
[0037] With regard, in particular, to the perimeter profile of said fabric element
4, according to the preferred embodiment represented in Figure 3, it features a first
progressive casting off
10 of the stitches at the level of both of the longitudinal sides
43 and
44, according to said advance direction indicated by the arrow
V. Said casting off
10 makes it possible to adapt the inner space that will be defined by the upper
3 to the progressive decrease in the diameter of the leg of the person who will wear
the footwear item
1.
[0038] Following said casting off
10 of the stitches, the perimeter profile of the same fabric element
4 includes a progressive increase
11 of the stitches at the level of said longitudinal sides
43 and
44, in such a way as to define the area corresponding to the heel of the person. Finally,
always following said advance direction
V, the fabric element
4 comprises a second progressive casting off
12 of the stitches at the level of both of the longitudinal sides
43 and
44, so as to define the profile assumed by the metatarsal area of the foot of said person
when the footwear item
1 is worn.
[0039] It cannot be excluded, however, that in different embodiments of the invention that
are neither described nor illustrated herein the perimeter profile of the fabric element
4 may have an outline that is different from that described for the preferred embodiment,
provided that it makes it possible to define an upper
3 that respects the shape of the leg and foot of the person who will wear the footwear
item
1.
[0040] According to the preferred embodiment of the invention, the fabric element
4 is at least partially obtained from yarns of the elastic type.
[0041] Advantageously, as previously mentioned, the use of said elastic yarns makes it possible
to conveniently deform the upper
3 in such a way that the inner space defined by it can be increased, therefore making
it easier for a person to put on the footwear item
1 of the invention. Furthermore, said elasticity of the upper
3 allows it to assume the shape of the person's leg and to properly adhere to the latter
once the footwear item
1 has been completely put on. Finally, according to the preferred embodiment of the
invention, the footwear item
1 comprises, arranged inside said space defined by the upper
3, rigid or semi-rigid elements
9 configured so as to at least partially maintain the shape of the footwear item
1, at least at the level of its tip and heel. In particular, said rigid or semi-rigid
elements
9 can be made of leather, a stiffened fabric or a plastic material.
[0042] It cannot be excluded, however, that in different alternative embodiments of the
invention the footwear item
1 may not be provided with said rigid or semi-rigid elements
9.
[0043] As previously mentioned, the invention includes also the method for making said footwear
item
1 of the invention.
[0044] In particular, according to said method, the first production step is the step of
making the fabric element
4 as a single piece through a weaving process.
[0045] It is important to underline that the study of the shape that said fabric element
4 will assume is previously carried out virtually by means of special computer programs.
Said computer programs, furthermore, are capable of translating the data of the defined
shape into "machine stitches" and transferring them to the loom, which will provide
for actually producing said fabric element
4. Advantageously, said first step of studying the shape makes it possible to skip said
steps of making the patterns and cutting the portions made of leather or other materials
envisaged by the methods of the known art, as previously described.
[0046] Furthermore, the availability of the virtual model of the footwear item
1 of the invention makes it possible to modify the aesthetic appearance of the same,
that is, to change the texture of its outer surface, with a simple procedure and substantially
at no cost, differently from that which happens when the footwear production methods
of the known art are used.
[0047] To go back to the weaving process, it preferably but not necessarily includes, as
previously mentioned, the use of a loom of the industrial type, capable of making
said fabric element
4 with the characteristics described below. This weaving process, in fact, includes
the production of the fabric element
4 comprising at least three areas
51, 52 and
53 adjacent to one another along the direction defined by its longitudinal axis
X. In particular, as already described above, the first area
51 is suited to at least partially enclose the leg of a person, the second area
52 is suited to enclose the tarsal part of the foot of said person, while the third
area
53 is suited to enclose the metatarsal part of said foot when the footwear item
1 of the invention is worn by the same person.
[0048] Furthermore, according to the method of the invention said fabric element
4 is made in such a way that, at least at the level of joining sections
61 and
62 interposed between said three areas
51, 52 and
53, it features a stitch pattern according to which the central stitches
7 are tucked with respect to the lateral stitches
8. This type of stitch pattern, as already explained, makes it possible to give the
fabric element
4 a three-dimensional shape with parabolic outline according to the direction defined
by the same longitudinal axis
X, as shown in Figure 4.
[0049] In the preferred embodiment of the invention, according to said method the fabric
element
4 is produced with a perimeter profile that is symmetrical with respect to the longitudinal
axis
X, as shown always in Figure 3 and as described above.
[0050] According to the method of the invention, the fabric element
4 is successively folded on itself along said longitudinal axis
X, as shown in Figure 5. It can be observed, in particular, that the symmetrical shape
of the fabric element
4 allows a perfect superimposition of the two symmetrical halves
41 and
42 and of the corresponding longitudinal sides
43 and
44.
[0051] According to the method of the invention, once said folding step has been completed,
said two longitudinal sides
43 and
44 are at least partially joined to each other in such a way as to define the upper
3 of the footwear item
1 of the invention, as shown in Figures 6 and 7.
[0052] According to the preferred embodiment of the invention described herein, said joining
step includes the sewing of the two longitudinal sides
43 and
44 to each other.
[0053] It cannot be excluded, however, that in different embodiments of the invention said
joining step may be carried out by glueing said two longitudinal sides
43 and
44 onto each other.
[0054] According to the method of the invention, at this point rigid or semi-rigid elements
9 are preferably but not necessarily inserted in the upper
3, at least at the height of the tip and the heel, said rigid or semi-rigid elements
being configured to maintain the shape of the footwear item
1 of the invention in said two areas.
[0055] It cannot be excluded, however, that in alternative embodiments of the method of
the invention said step of inserting the rigid or semi-rigid elements
9 may be absent.
[0056] Finally, as shown in Figure 8, the method of the invention includes a further step
of at least partially connecting the lower edge
31 of the upper
3 with the perimeter area
21 of the sole
2, in such a way as to complete the production of the footwear item
1 of the invention shown in Figure 1.
[0057] According to the above, therefore, the footwear item of the invention and the method
of the invention for making the same achieve all of the set objects.
[0058] In particular, the invention achieves the object to provide a footwear item structured
in such a way as to make it possible to drastically reduce the steps that are necessary
for its production.
[0059] Another object achieved by the invention is the object to provide a footwear item
structured in such a way as to make it possible to reduce, if not to eliminate, the
waste material generated during its production steps. Consequently, to advantage,
for the definition of the final cost of the footwear item it is no more necessary
to take in consideration the costs deriving from the generation and the disposal of
scraps, with consequent economic advantages.
[0060] A further object achieved by the invention is the object to provide a footwear item
structured in such a way as to make it possible to reduce, if not to eliminate, those
production steps that require human labour.
[0061] Consequently, the invention achieves the object to provide a footwear item structured
in such a way that it can be produced in series while at the same time guaranteeing
a high degree of uniformity among the items produced in the same production lot.
[0062] Finally, the invention also achieves the object to provide a footwear item structured
in such a way as to make it possible to modify its aesthetic appearance with a simple
procedure and at no cost.
