Description
FIELD OF THE INVENTION
[0001] The present invention pertains to footwear. More
specifically the invention relates to a process for production of a
fastening system of interchangeable straps in sandals in accordance
with the preamble of patent claim 1. The invention relates to a
type of personal item designed to meet human needs.
PRIOR ART
[0002] The footwear industry, in order to meet a human need, has
gradually been developing and manufacturing more refined models
whose production, from a technical point of view, is becoming
increasingly complex.
[0003] The primary use of footwear is to protect people's feet.
Today, however, shoes are purchased based on criteria related to
fashion trends and are used as a fashion accessory and as a
complement to external image, more commonly known as "look".
[0004] The footwear industry, in response to market demand, has
been creating several alternatives to traditional shoes and the
concept of shoes with interchangeable elements, particularly
interchangeable straps, is already known.
[0005] However, already known footwear with interchangeable
elements is not, due to its intrinsic characteristics, intended to
facilitate the interchangeability of certain components to enable
shoes to be differently configured while retaining an attractive
aesthetic appearance which enables them to be used with different
clothing styles, materials and colours.
[0006] As can be seen in U.S. Pat. No. 4,461,102, shoes that change
appearance by replacement of straps are provided.
Interchangeability of the straps is made possible by a fastening
mechanism consisting of spring connectors attached to the ends of
each strap employed with the shoe where each spring connector
includes at least one loop spring which engages a stud securely
fixed to the lower part of the shoe.
[0007] U.S. Pat. No. 5,992,058 provides for a shoe system with
interchangeable elements whose fastening device consists of snap
fasteners, located on the perimeter of the shoe sole, to which
several flexible straps can be attached, said straps having a pair
of opposite ends detachable from the sole and the heel of the shoe
is also interchangeable via a screw to which the desired heel must
be connected.
[0008] US patent No. 2002194750 provides for a shoe with a
removable upper whose fastening mechanism consists of receiving
openings in recesses located on the base of the shoe and fasteners
which are coupled with said openings, which are located on said
removable uppers.
[0009] US patent No. 2003233772 provides for interchangeable shoe
coverings in which the fastener may consist of hooks, straps, snaps
or laces.
[0010] US patent No. 200726650 provides for a shoe with two
components which are independent of one another and
interchangeable, namely an ankle strap with a fastening device
consisting of snap fasteners which can be attached by means of
rivets, adhesives or other known means and a vamp whose fastener
also consists of snaps that can be attached using rivets, adhesives
or other known means.
[0011] US patent No. 2007209238 provides for a vamp for use in
shoes with interchangeable components, the vamp consisting of ends
that include fasteners that interconnect with fasteners positioned
on the edge of the shoe base.
[0012] US patent No. 2004064976 provides for an interchangeable
shoe ensemble which includes a base member having snap fasteners
along its periphery and positioned for connection to the
corresponding snap fasteners on the interchangeable upper.
[0013] US patent No. 2004064976 [sic] provides for a shoe whose
sole includes foldable iron accessories that are attached to each
end of the shoe upper and said upper is interchangeable.
[0014] None of the above documents provides for a system with one
or more interchangeable uppers that are easily replaceable and
fastened so as to provide comfort and safety to the user and which,
at the same time, do not compromise the aesthetic appearance of the
shoe.
[0015] Accordingly, it would be useful to provide a process for
production of a fastening system for interchangeable straps in
sandals and other products, obtained according to said process,
which is functional to the extent that it provides comfort and
safety to the user and at the same time has an aesthetic function
by providing a pleasing outer appearance.
SUMMARY OF THE INVENTION
[0016] The present invention seeks to overcome these problems
through a process for the production of a fastening system of
interchangeable straps for sandals that is different from existing
processes and has specific features in terms of fasteners.
[0017] The present invention presents a process for production of a
fastening system of interchangeable straps in sandals that is
different from conventional processes because it includes the
following steps: preparation of the base by creation of several
apertures in its material; coating of said base with adhesive for
attachment of the material composing the outer layer of the
platform, to secure the sole and the insole; application of a
fastener within said base, piercing the outer layer of the
platform, by pressure on the support which is traversed by said
fastener which is inserted inside the base and passes through
multiple apertures and is fastened permanently; fastening of said
fastener ensuring so that the support remains a reasonable distance
from the platform.
[0018] The platform of the fastening system of interchangeable
straps in sandals may be with or without a heel and may adopt
several configurations and aesthetic decorations. The fasteners
applied inside the base may be affixed to the extension of the
periphery of the platform with a heel or positioned on the upper
face of the insole of the base without a heel. The interchangeable
straps that are combinable with one another are replaced by
disengaging and engaging the buttonholes on the supports. The
straps can also be fastened permanently to a platform with a heel
or without a heel.
[0019] The present invention allows the user to wear sandals in
different contexts by changing the strap to suit the outfit and
personal taste, while ensuring, at the same time, comfort in use
through the possibility of selecting the base that best fits the
size and shape of the foot and the strap whose size is suitable for
providing stability and comfort.
[0020] The present invention provides for a system allowing
replacement of straps which, furthermore, can be combined with each
other, allowing different colours and types of straps with the
inherent ability of change in aesthetic appearance which,
accordingly, allows numerous different models of sandals to be
configured.
[0021] The present invention enables the physical space occupied by
the shoe to be reduced as it provides for numerous different sandal
models using a single platform to which interchangeable straps are
connected providing for the composition of several sandal
models.
[0022] The present invention provides for a system in which
particular components, namely the platform and straps, can be of
sizes that can be combined with each other to enable the sandal to
fit the foot of each individual user, in a way that traditional
footwear cannot.

DETAILED DESCRIPTION OF THE INVENTION
[0039] The present invention provides a process for the production
of a fastening system of interchangeable straps in sandals
comprising the following steps: [0040] preparation of the base (1)
through material that is sufficiently rigid to house fasteners
inserted into its structure, in which numerous apertures are
created (2); [0041] coating of said base (1) with adhesive material
to fix the layer, preferably of cork, that forms the outer of the
platform (9, 14) and to fix the sole (22), preferably of rubber and
to fix the insole (21), preferably of imitation leather; [0042]
application of a fastener (8), preferably of cylindrical shape,
inside said base (1) puncturing the outer layer of the platform (9,
14) by means of pressure on the support (3a, 3b, 3c, 5a, 5b, 5c, 6,
7, 15), which is preferably round, which is traversed by said
fastener (8) which is inserted into the base (1) and there pierces
numerous apertures (2) and is fastened permanently; [0043]
fastening of said fastener (8), preferably of cylindrical shape,
ensuring that the support (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15)
remains sufficient distance from the platform (9, 14) to enable the
interchangeable straps to be engaged and disengaged.
[0044] This fastening system of interchangeable straps in sandals,
obtained in accordance with the process described in the previous
paragraph, consists of a platform with a heel (9) or without a heel
(14) which can adopt several configurations and aesthetic
decorations, using supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15)
which may be affixed to the extension of the periphery of the
platform with a heel (9) or positioned on the insole (21) of the
platform without a heel (14), using interchangeable straps (4a, 4b,
4c, 12a, 12b, 16) that can be combined with each other, by straps
(13, 17, 19) fastened permanently to the platform with a heel (9)
or without a heel (14) and by fasteners (10, 11, 18, 20) integrated
in the straps (13, 17, 19) permanently fastened to the platform
with a heel (9) or without a heel (14.
[0045] The present fastening system of interchangeable straps in
sandals has a platform that can be with a heel (9) or without a
heel (14) in which the base (1) is formed of a resistant material
that is sufficiently rigid to house fasteners inserted into its
structure, preferably of polyurethane which is a polymer designated
by the acronym PU. The platform with a heel (9) and without a heel
(14) may be coated with various materials and can therefore adopt
several configurations and aesthetic decorations. The platform with
a heel (9) can vary in terms of heel height and shape.
[0046] The present fastening system of interchangeable straps in
sandals includes supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15) which
may be affixed to the extension of the periphery of the platform
with a heel (9) or positioned on the insole (21) of the platform
without a heel (14). The supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7,
15) are made of a resistant material that is sufficiently rigid to
enable the straps to be engaged and disengaged, preferably
stainless steel and therefore highly resistant to oxidation and,
accordingly, susceptibility to deterioration due to rusting. These
supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15) are traversed by a
fastener (8) inserted into the base (1) by means of pressure on
said supports, perforating the outer layer of the platform (9, 14)
and passing through multiple apertures (2) and being fastened
permanently in the base (1) preventing them coming loose from their
position. The number and position of the supports (3a, 3b, 3c, 5a,
5b, 5c, 6, 7, 15) in the base (1) may vary to allow different
models of shoes to be configured by applying the same fastening
system of interchangeable components. The supports (3a, 3b, 3c, 5a,
5b, 5c, 6, 7, 15) are placed at strategic locations to ensure
comfort of the foot provided by the stable, safe properly fitted
engagement of each strap and the fasteners (8) ensure that said
supports are affixed and prevent them coming loose from their
location. The aesthetic decorations of said supports may vary.
[0047] This fastening system includes interchangeable straps (4a,
4b, 4c, 12a, 12b, 16) that can be combined with each other. These
interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) are composed of
three distinct layers, namely: the outer layer consists of a
section whose size, material of composition, colour or colours may
vary based on the time of year and seasonal collection, the middle
layer consisting of a resilient material that ensures the
durability, shape and comfort of the strap and whose size, material
of composition and colour or colours may vary, the inner layer
consisting of an anti-allergic material which provides comfort to
the user when wearing the sandals. These interchangeable straps
(4a, 4b, 4c, 12a, 12b, 16) have a finish consisting of special
stitching that is strengthened around the buttonholes which engage
the supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15) and fasteners (10,
11, 18, 20) integrated in the straps (13, 17, 19) to prevent the
interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) being excessively
damaging by and during movement of the wearer's foot. The length of
the interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) is variable
to enable them to be engaged on the supports (3a, 3b, 3c, 5a, 5b,
5c, 6, 7, 15). The size, material of composition, colour or
colours, configuration and aesthetic decorations of the
interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) are variable so
as to provide the sandals with several aesthetic appearances
provided by use thereof. The interchangeable straps (4a, 4b, 4c,
12a, 12b, 16) are easy to change as it is only necessary to engage
the buttonholes on the supports (3a, 3b, 3c, 5a, 5b, 5c, 6, 7, 15)
and fasteners (10, 11, 18, 20) integrated in the straps (13, 17,
19).
[0048] This fastening system includes interchangeable straps,
includes straps (13, 17, 19) that are permanently fixed to the
platform with a heel (9) or without a heel (14) to which the
interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) are connected.
The configuration and aesthetic decoration of the straps (13, 17,
19) may vary.
[0049] This fastening system includes interchangeable straps,
includes fasteners (10, 11, 18, 20) integrated in the straps (13,
17, 19) fastened permanently to the platform with a heel (9) or
without a heel (14) that enable interconnection of the
interchangeable straps (4a, 4b, 4c, 12a, 12b, 16) to the straps
(13, 17, 19). The configuration and aesthetic decoration of the
fasteners (10, 11, 18, 20) may vary.
Preferred Embodiment of the Invention
[0050] Preparation of the base (1) through material of sufficient
rigidity to house fasteners inserted in its structure, in which
numerous apertures are created (2); Coating of said base (1) with
adhesive material to fix the layer, preferably of cork, that forms
the outer of the platform (9, 14) and to fix the sole (22),
preferably of rubber and to fix the insole (21), preferably of
imitation leather; Application of a fastener (8), preferably of
cylindrical shape, inside said base (1) puncturing the outer layer
of the platform (9, 14) by means of pressure on the support (3a,
3b, 3c, 5a, 5b, 5c, 6, 7, 15), which is preferably round, which is
traversed by said fastener (8) which is inserted into the base (1)
and there passes through multiple apertures (2) and is fastened
permanently; Fastening of said fastener (8), preferably of
cylindrical shape, ensuring that the support (3a, 3b, 3c, 5a, 5b,
5c, 6, 7, 15) remains sufficient distance from the platform (9, 14)
to enable the interchangeable straps to be engaged and disengaged.
The platform with a heel (9) may be coated with various materials
and may therefore take numerous appearances and may also be of
different heights and heel shapes. To provide comfort, three
supports (3a, 3b, 3c) are affixed to this platform (9) at strategic
locations on the extension of the right side section of the
periphery of the platform and three supports (5a, 5b, 5c) on the
extension of the left side section of the periphery of the platform
and these are affixed by said fastener (8) which traverses said
supports, which is inserted into the base (1) and there passes
through multiple apertures (2) and is fastened permanently. These
supports (3a, 3b, 3c, 5a, 5b, 5c) are made of resistant material
that is sufficiently rigid to enable engagement and disengagement
of the straps. The aesthetic decoration of the supports (3a, 3b,
3c, 5a, 5b, 5c) may vary. Three interchangeable straps (4a, 4b, 4c)
of variable length and material and colours are engaged on the
supports (3a, 3b, 3c, 5a, 5b, 5c) at the buttonhole section. These
interchangeable straps (4a, 4b, 4c) consist of three distinct
layers, namely: an outer layer whose size, material and colour may
vary, the middle layer whose material provides comfort and
durability to the strap and whose size, composition and colour may
vary and the inner layer consisting of an anti-allergic material
that provides comfort to the user when using the sandals. The
interchangeable straps (4a, 4b, 4c) have a special stitching that
is strengthened around the buttonholes which engage the supports
(3a, 3b, 3c, 5a, 5b, 5c) to prevent them being excessively damaged
by their use. The interchangeable straps (4a, 4b, 4c) are changed
by disengaging the supports (3a, 3b, 3c, 5a, 5b, 5c) from the
buttonholes.
