1. Technical field
[0001] The present invention relates to a system for individualizing a shoe, in particular
kids' shoes.
2. The prior art
[0002] Shoes are nowadays mass products, wherein identical models are produced in high numbers
for reducing the manufacturing costs. Although there is a great variety of models
on the market, selecting a shoe with respect to its outer appearance is generally
limited to given shoe models.
[0003] At the same time, there is a trend for individualization in many areas of society.
The wearer of a shoe wants to identify with his shoe and to make it different from
other shoes. For example, major shoe manufacturers now offer the possibility to configure
a shoe over the internet within certain limits and to arrange the name of the owner
on the shoe. However, this does not provide a real individual design of the shoe.
Furthermore, the configuration requires a knowledge which many customers are lacking,
in particular kids.
[0004] In order to overcome these disadvantages, several approaches are known in the prior
art. For example, applicant of the present application distributed already in the
mid-80s shoes for kids having a white upper together with a set of pens for individually
designing the shoe. However, the achieved result was not always aesthetically pleasing.
[0005] Other approaches allowing an individualization of the outer design are known from
the
US 5,673,501 and the
US 5,136,726. The
US 5,673,501, for example, discloses a shoe wherein a number of attachment means are integrated
into the shaft. The attachment means operates similar to a snap-on device and allows
the attachment of different decorating elements such as a ribbon or the like depending
on the preferences of the wearer. However, these elements can only be arranged at
locations of the few predetermined attachment means of the shaft.
[0006] The
US 5,136,726 discloses a shoe wherein almost the entire outer surface comprises a fabric forming
a hook and loop fastener together with another fabric on the backside of a decorative
element. Therefore, one or more decorative elements can be almost arbitrarily distributed
on the surface of the shoe. However, the limitation to a fabric which forms one side
of a hook and loop fastener not only strongly impairs the usability of the shoe but
also its outer appearance. Furthermore, there is the risk that the upper material
becomes permanently dirty when using the shoe according to the
US 5,136,726. This is, since the required open structure of the upper material will very easily
take up soiling.
[0007] According to one aspect, the present invention is therefore based on the technical
problem to provide a system for individualizing a shoe, which presents on the one
hand a large amount of design freedom for the exterior of the shoe, but which is on
the other hand easy to use and furthermore does not impair the practical usability
of the shoe.
3. Summary of the invention
[0008] The present invention solves this problem by a system for individualizing a shoe
comprising a shoe with a surface region, which includes at least one first design
element, and at least one second design element, wherein the second design element
comprises a contact surface and wherein the contact surface and/or the surface region
are provided such that the second design element can be rubbed at an arbitrary location
onto the surface region of the shoe.
[0009] The system according to the invention allows the easy realization of an unlimited
number of different overall designs of a shoe by rubbing one or more second design
elements at different locations onto the surface region of the shoe. As a result,
no shoe is identical to another, which leads to the highest degree of individualization.
[0010] In the presently preferred embodiment, the system comprises a plurality of second
design elements, each of which has smaller dimensions than the surface region of the
shoe. As a result, there is a high degree of flexibility where and in which combinations
the plurality of second design elements can be arranged on the surface region of the
shoe with the first design element. The surface region is preferably provided on the
instep and/or the sides of the upper of the shoe.
[0011] If the first design element and the at least one second design element are thematically
adapted to each other, particularly advantageous overall aesthetic impressions are
easily obtained.
[0012] In a particular flexible embodiment of the system according to the invention, the
surface region of the shoe and/or the contact surface are provided such that the at
least one second design element is removable from the surface region without damaging
the first design element. To this end, the system comprises preferably a removing
means to remove the second design element from the surface region of the shoe.
[0013] According to a further aspect of the invention, the system comprises in addition
a rubbing element for rubbing the second design element onto the surface region. The
rubbing element comprises preferably a handle region and a rubbing region and becomes
wider in the direction from the handle region to the rubbing region. In addition,
it is preferred, if the rubbing element comprises an attachment opening so that it
can be mounted like a key-fob.
[0014] Preferably, the first design element has on the surface region an abrasion resistance
such that it substantially survives without damage an abrasion test with sandpaper
with 280 graining and a pressure force of approx. 9.8 N of preferably 200 cycles,
particularly preferably 300 cycles. The second design element preferably has material
properties such that it is substantially removed from the surface in an abrasion test
with a linen and a pressure force of approx. 9.8 N after 20 - 30 cycles, particularly
preferred 25 cycles. The combination of these preferred material properties makes
it possible in a particularly advantageous manner to repeatedly arrange and remove
second design elements on the surface without damaging the first design element.
4. Short description of the accompanying figures
[0015] In the following, aspects of the present invention are further discussed with reference
to the accompanying figures. These figures show:
Fig. 1: A schematic general view of a presently preferred embodiment of the system
according to the invention;
Fig. 2: An exemplary view of an individualized shoe; and
Fig. 3: An embodiment of a preferred rubbing element for the system according to the
invention.
5. Detailed description of preferred embodiments
[0016] In the following, embodiments of the system according to the invention are further
described with reference to the example of an individual design of kids' footwear.
However, it is to be understood that the system according to the invention can also
be used to easily individualize the design of other types of shoes independent from
their field of use and size.
[0017] Fig. 1 presents a general view of a shoe 10 and a set of rub-on pictures 20. The
shoe 10 comprises a common upper, having an instep region 11 and side regions 12.
A plurality of first design elements 15 are permanently arranged on the instep region
11 and the side regions 12, for example by imprinting the material of the upper (leather,
patent leather or the like) before, during or after the manufacture of the shoe 10.
Imprinting can be done via screen-printing, sublimation printing or transfer printing.
Other manufacturing techniques are also conceivable. For example, the first design
elements 15 can also be generated by coining, punching, gluing or other techniques,
which do not only generate a two-dimensional design of the surface but design the
corresponding region of the shoe three-dimensionally, similar to a relief. The shaping
of the relief can predetermine positions where second design elements 21 are preferably
to be arranged.
[0018] As shown in Fig. 1, a few stars and a moon are arranged in different locations of
the shoe 10 being examples for first design elements 15. Additionally, parts or the
overall design region of the upper of the shoe, i.e. the instep 11 and the side surfaces
12 of the present embodiment, may be provided with one or more background colors or
the like, e.g. a black color corresponding to the stars and the moon (not shown in
Fig. 1).
[0019] Alternatively or in addition to the instep 11 and the side regions 12, also other
regions of the the shoe, for example the tongue or side areas of a midsole and / or
the outsole, may be provided with first design elements or a background colour (not
shown).
[0020] The rub-on pictures are provided as a set 20 on a foil or a similar carrier, which
is known per se. As indicated by the dashed arrow in Fig. 1, individual pictures 21
may be transferred by rubbing onto a desired location of the instep 11 and / or the
side areas 12. Based on the selection of the rub-on pictures to be transferred and
their arrangement, there is an unlimited number of design options so that each shoe
designed with the system according to the invention has finally an individual appearance.
This is, since the rub-on pictures are each significantly smaller than the available
surface on the instep 11 or the side 12. Additionally, there are no high requirements
on the artistic or technical skills of the designer. For example, even a child may
right away arrange the rub-on pictures of the set 20 in the desired positions on the
instep 11 or the side surface 12 of the shoe 10.
[0021] Preferably, the set of rub-on pictures 20 relates to the same topic as the design
elements 15, which are permanently arranged on the upper material of the shoe 1. In
Fig. 1, for example, the shoe 10 presents a scenery at night and the set 20 of rub-on
pictures comprises ghosts or the like. Other combinations are also conceivable.
[0022] Fig. 2 presents an example of the fully designed shoe having as a first design element
15 a meadow. In this embodiment, three corresponding second design elements 21 were
rubbed-on, namely a balloon, a butterfly and a beetle. As can be seen, the rubbed-on
design elements 21 and the predetermined design elements 15 can barely be distinguished
in the finished shoe. Accordingly, in spite of having been individually designed,
the shoe 10 created with the system according to the invention meets the highest quality
requirements concerning the execution of a design.
[0023] A particular good and long-lasting attachment of the rubbed-on pictures 21 is achieved
if the surface region, where the rubbed-on pictures are arranged, as well as the rub-on
pictures themselves, have specific material properties. Preferably, the first design
elements 15 are arranged with a larger degree of abrasion resistance than the abrasion
resistance resulting for the rubbed-on second design elements.
[0024] Particularly preferred is an arrangement in which the first design elements substantially
survive an abrasion test according to DIN EN-ISO 11640 with a 280-graining sandpaper
without visible damage. To this end, a stamp provided with the sandpaper is moved
over the surface region with a pressure force of 9.8 N and the first design elements
are subsequently examined for visible damage. The screen-print or the other method
used for applying the first design elements 15 should preferably be made such that
this test is survived at 200, preferably 300 movement cycles, i.e. that substantially
no damage to the first design elements 15 can be seen.
[0025] The rubbed-on second design elements 21 preferably have material properties such
that a clearly reduced abrasion resistance results. Here, it is preferred if the second
design element 21 is substantially removed from the surface in an abrasion test according
to DIN EN-ISO 11640 with a linen and again a stamp with a pressure force of 9.7 N
after 20 - 30 cycles, preferably 25 cycles, so that other design elements 21 can be
applied. The indicated preferred values of the abrasion resistance of the first and
second design elements 15, respectively 21, enable the realization of many different
aesthetic overall impressions of the shoe with the inventive system. However, alternatively
it is also conceivable to add a clear coat to the system according to the invention
which can be used to cover once rubbed-on pictures 21 to protect them permanently
against damages (not shown).
[0026] However, a modified embodiment is also possible wherein the rubbed-on pictures 21
are even more easily removable, e.g. due to different surface properties of the respective
surface region of a shoe and / or due to a different composition of a contact surface
of a rub-on picture. Removing a rubbed-on picture can also be achieved by mechanical
scratching or by using a suitable solvent, e.g. a common nail-polish remover. In this
case, the shoe may be repeatedly re-designed over its lifetime in a particularly simple
manner. In this case, it may be advantageous if the shoe regions provided with the
first design elements 15 are additionally provided with a coating preventing an unintentional
damage when removing the rub-on images. This coating can be applied by different techniques,
e.g. spraying on or laminating.
[0027] Fig. 3 presents a preferred tool 30 for rubbing-on, which has a shape somewhat similar
to a miniaturized dented spray can. The lower part 31 of the tool 30 provides the
rubbing area allowing a controlled transfer of a rub-on picture 21 onto the desired
location of the instep 11 or a side region 12 or the like by putting the picture onto
the shoe and rubbing from above forth and back on the carrier foil. The upper part
32 of the rubbing tool 30 serves preferably as a handle region and can due to its
limited dimensions easily be held by children's hands.
[0028] On top of the handle region 32, there is preferably a mounting projection 33 comprising
an opening 34. The opening 34 allows attaching the small tool 30, for example to a
key ring. Using this preferred embodiment, however, is not inevitable. Other rubbing
tools such as suitable wooden plates can also be used. In fact, the tool 30 is not
required at all and the rub-on pictures can be rubbed on using finger nails or the
like.
[0029] The rub-on tool 30 is preferably made from a sufficiently soft plastic material to
avoid damages to the first design elements 15 during rubbing.
