Description
[0001] The invention relates to a shoe, especially a sports shoe,
which comprises a sole element and a shoe upper part, wherein the
sole element and the shoe upper part are thereby held together that
a wire-like connection element is guided through eye- or tube-like
sections at the sole element and at the shoe upper part.
[0002] Such a shoe is known for example from US 2009/0313851 A1.
Here, the shoe upper part has tube-like sections at its bottom
side. The sole has groove-like recesses at its upper side in which
the tube-like sections of the shoe upper part can mesh. Between two
of those recesses a tube-like section is provided in the sole. So,
when the shoe upper part is put on the sole a circumferential tube
structure is formed in which a wire can be inserted to connect shoe
upper part and sole connected with another detachably. For this the
sole comprises in its lateral region an insertion and export
channel for the wire which allows the wire to enter said tube
structure.
[0003] So, the sole and the shoe upper part can be connected
detachably, wherein the wire is removed via the insertion and
export channel for detaching both parts. This can be used at the
one hand to separate the sole and the shoe upper part, which
consist normally from different materials, for recycling.
Otherwise, so it is generally possible to exchange the shoe upper
part and the sole and to continue the use of the respective other
part.
[0004] It is detrimental at the mentioned pre-known solution that
the production especially of the sole is relatively elaborate and
thus expensive. Furthermore, the thread of the connection wire
through the insertion and export channel is relatively complex and
time-consuming. In the case of pollutions and blockage of the
insertion and export channel it can be problematic at all to obtain
access to the wire to remove the same and to insert a new wire
respectively.
[0005] It is the object of the invention to further develop a shoe
of the generic kind that it becomes possible in an easier manner to
establish and to release the connection between the shoe upper part
and sole by means of the wire-like connection element. Thereby, at
the one hand the possibility should be improved to separate the
shoe in the case of recycling, i. e. to separate the shoe upper
part and sole from another. Otherwise, an improved possibility
should be created to separate the shoe upper part and the sole from
another if required and to put together again by means of the
wire-like connection element.
[0006] The solution of this object by the invention is
characterized in that the eye- or tube-like sections are arranged
in a lateral outer region of the sole element and that the eye- or
tube-like sections are arranged in a lateral outer region of the
shoe upper part.
[0007] The eye- or tube-like (tubular-shaped) sections at the sole
element and the eye- or tube-like sections at the shoe upper part
are preferably arranged aligned--seen in circumferential direction
of the shoe--at connected sole element and shoe upper part and are
arranged alternating along the circumference of the shoe. The eye-
or tube-like sections at the sole element and the eye- or tube-like
sections at the shoe upper part form thereby preferably a
complementary and substantial closed eye- or tube-like structure
along the whole circumference of the shoe.
[0008] According to a preferred embodiment of the invention the
shoe upper part is designed at least partially as an at least
two-layer structure and comprises an outer part and an inner part,
especially a lining, wherein the inner part is designed
circumferential around the bottom side of the shoe upper part and
lays on the sole element at connected sole element and shoe upper
part.
[0009] Preferably, the eye- or tube-like sections at the sole
element are formed directly from the material of the sole element
at the same.
[0010] The eye- or tube-like sections at the sole element can
comprise a slit which slit runs in the direction of the outer
circumference of the shoe and which slit is arranged a the face
side of the eye- or tube-like sections which is directed outside
away from the shoe. Thereby, the thread of the wire-like connection
element can be facilitated.
[0011] The eye- or tube-like sections at the shoe upper part can be
formed by a loop-like stitched section of the shoe upper part,
especially of the outer part of the two-layer formed shoe upper
part.
[0012] The sole element can comprise a composite part which
comprises at least an outer sole and a midsole. But it is also
possible that the composite part is made as a one-part element. In
this case the midsole can simultaneously form the outer sole;
thereby, then a respective dense and abrasion-proof material is
beneficial.
[0013] In case that the composite part consists of midsole and
outer sole preferably a foamed material for the midsole is used
while the outer sole is then rather made from a compact material;
it can consist of rubber or plastic material.
[0014] According to a further preferred embodiment of the invention
the sole element comprises a lattice frame structure, wherein the
eye- or tube-like sections are parts of the lattice frame
structure. The lattice frame structure comprises preferably a
number of lattice rods which are connected with another. The sole
composite part can thereby comprise groove-like recesses at its
bottom side which are adapted to the run of the lattice rods,
wherein the lattice frame structure and the composite part are
connected with another form-fitted by sticking together.
Preferably, the connection is thereby established not by glueing
but only by form-fit and frictional engagement which results from
the same. Respectively at least two lattice rods lead thereby
preferably in an eye- or tube-like section and fix the same at the
lattice frame structure.
[0015] The lattice frame structure is preferably produced from a
plastic material, especially from a compact plastic material, while
the composite part is produced from plastic materials, especially
at least partially (as mentioned) from foamed plastic, wherein the
plastic material of the lattice frame structure is harder than the
plastic materials of the composite part.
[0016] The wire-like connection element is preferably a tensile
strength rope, wherein the rope consists preferably from plastic
material or comprises plastic material. The two ends of the
wire-like connection element can be connected together by a
clamping element.
[0017] With the proposed design of a shoe it becomes possible in an
easy manner to connect the shoe upper part with the sole
detachably. The assembly of the two parts by means of a rope and
wire respectively is easy possible due to the defined alignment of
the eye- or tube-like sections at the sole element and at the shoe
upper part and the rope and wire respectively can be inserted
easily. The releasing of the two parts (shoe upper part and sole)
is also possible easily.
[0018] The shoe upper part (bootleg) and the sole of the shoe
consists normally of different materials which can hardly be
re-used in the assembled or connected state by means of recycling
and which are only limited bio-degradable as a whole.
[0019] But the proposed concept allows it in an easy manner to
connect and also to separate the upper part and the sole. The sole
and the upper part are connectable and connected respectively by
means of a wire-like connection element (cord) by the mentioned
eye- or tube-like sections at the shoe upper part and at the sole.
The cord is connected detachably at its ends.
[0020] At the recycling of the shoe the cord is released and pulled
out of the shoe; thereby the sole and the upper part separate from
another and can be recycled separately.
[0021] In the drawing embodiments of the invention are shown.
[0022] FIG. 1 shows the side view of a shoe which comprises a shoe
upper part and a sole connected with the same,
[0023] FIG. 2 shows the section A-B according to FIG. 1,
[0024] FIG. 3 shows in a perspective view a section of the sole in
the region of the section A-B according to FIG. 1,
[0025] FIG. 4 shows the section C-D according to FIG. 1,
[0026] FIG. 5 shows in a perspective view a section of the shoe in
the region of the section C-D according to FIG. 1,
[0027] FIG. 6 shows schematically the section E-F according to FIG.
1 with the depiction of tube-like sections at the sole element and
at the shoe upper part and
[0028] FIG. 7 shows in a perspective view a lattice frame structure
which is part of the sole element.
[0029] In FIG. 1 a shoe 1 is shown in the side view. It has a sole
element 2 as well as a shoe upper part (bootleg) 3. Both parts 2
and 3 are connected with another detachably. The connection of the
two parts takes place presently by a plurality of tube-like
(tube-shaped) sections 5 and 6, which are arranged at the sole
element 2 and at the shoe upper part 3 respectively. As can be seen
from the section E-F, which is shown in FIG. 6, the sections 5 of
the sole element 2 and 6 of the shoe upper part 3 complement one
another so that a closed circumferential tube-shaped structure is
given which surrounds the whole circumference of the shoe 1 when
the sole element 2 and the shoe upper part 3 are connected together
as it corresponds to the status during intended use of the shoe 1.
In this tube-shaped structure a wire-like connection element 4
(rope) is thread and so the both parts 2 and 3 are connected with
another detachably.
[0030] The design of the sole element 2 is apparent from the FIGS.
2 and 3, that one of the shoe upper part 3 from the FIGS. 4 and
5.
[0031] Accordingly, the sole is composed in longitudinal direction
of the shoe alternating sections--as becomes apparent from the
synopsis of FIGS. 1, 3 and 5. In the region of a tube-like section
5 at the sole element 2 (see FIG. 3) the sole element 2 has a
two-part outer sole 11 with a first inner part 11' and a second
outer part 11''. In the region of a tube-like section 6 at the shoe
upper part 3 (see FIG. 5) the sole element 2 has, concerning to the
outer sole 11, only the outer part 11''.
[0032] However, a midsole 12 extends along the whole longitudinal
extension of the shoe and the sole respectively.
[0033] The outer sole 11 and the midsole 12 are thereby connected
to a composite part which comprises the tube-like sections 5 in its
edge regions for threading the rope. However, between two adjacent
sections 5 a recess is located which is designed for entering of
the sections 6 of the shoe upper part 2 when the shoe upper part 3
is put on the sole element 2.
[0034] The firm connection between sole element 2 and shoe upper
part 3 is then established by threading of the rope 4 into the
sections 5, 6.
[0035] The shoe upper part 3 is designed two-layer in the
embodiment. It has an outer part 7 and an inner part 8 in the form
of a lining which are connected with another (for example glued).
As can be best seen in FIG. 5 the outer part 7 is sewed at two
locations of a seams 15 and 16 with the inner part 8 in such a
manner that a loop is created which forms the tube-like section 6
at the shoe upper part 3. In this stitched region a band running in
circumferential direction (e. g. a leather tape 17, see FIG. 4) can
be inserted between the outer part 7 and inner part 8 and stitched
for reinforcement.
[0036] As can be seen in FIG. 2 and in FIG. 4 the tube-like
sections 5 at the sole element 2 can be provided with a slit 9 at
its outwards directed face side 10 which slit is running in
circumferential direction. By the slit it becomes possible in an
easy manner to clip the rope 4 in the tube-like section 5 during
the connection of shoe upper part 3 and sole element 2.
[0037] A further preferred embodiment can be seen in FIG. 7 which
shows a lattice frame structure 13. This structure comprises a
plurality of lattice rods 14 at which ends the tube-like sections 5
are formed. In this case, the outer sole 11 and the midsole 12
respectively are provided with groove-shaped recesses in which
lattice rods 14 of the lattice frame structure 13 are inserted (see
the explanations below).
[0038] Thus, according to the preferred embodiment the sole element
2 consists of a midsole 12 which consists preferably from a
sustainable recyclable and/or bio-degradable plastic material.
Below the midsole 12 the outer sole 11 is arranged which consists
in sections of two parts 11' and 11'' (namely in the region of the
extension of the eye- or tube-like sections 5 at the sole element
2, see FIG. 3) and in sections only of one part 11' (namely in the
region of the extension of the eye- or tube-like sections 6 at the
shoe upper part 3, see FIG. 5). An outer appearance of the shoe 1
results as can be seen in FIG. 1.
[0039] The lattice frame structure 13 (lamella structure) is part
of the sole element 2 and is embedded into the outer sole 11 and
also in the midsole 12 respectively in such a manner that in the
outer sole 11 and the midsole 12 respectively groove-shaped
recesses are placed at the bottom side (formed at injection
moulding of the parts) which correspond to the run of the lattice
rods 14 of the lattice frame structure 13. The lattice frame
structure 13 can thus be form-fit stuck together with the midsole
and outer sole 11, 12. Hereby, due to the width dimension of the
lattice rods and the groove-shaped recesses respectively and their
toleration relative to another also a frictionally engagement is
created.
[0040] The groove-shaped recesses allow thus an accurately fitting
pressing of the lattice structure with its lattice rods 14 in the
outer sole and midsole respectively. This takes place preferably
without the use of an adhesive.
[0041] The lattice structure 13 extends totally or also only
partially along the bottom of the midsole 12 and of the shoe
respectively till the lateral region of the shoe upper part 3. The
lattice frame structure 13 is held by the wire-like connection
element at the shoe upper part 3. For doing so the connection
element 4 is guided alternating through the eye- or tube-like
sections 5 at the sole element 2 and through the eye- or tube-like
sections 6 at the shoe upper part 3.
[0042] The tube-shaped sections 5 connect two or more lattice rods
14. The tube-shaped sections 5 are preferably open to the bottom
side or to the face side 10 which is directed away from the shoe
inner, i. e. they have a slit 9 here; this facilitates the
insertion of the cord. Insofar the sections 5 are designed
hook-shaped; the cord can then be hooked or clipped in from the
bottom side in an easy manner so that a threading is not
necessary.
[0043] The tube-like sections 5 at the sole element 2 are chosen
with respect to their arrangement and length in such a manner that
at the one hand an even fixation of the lattice frame structure 13
at the shoe upper part 3 is enabled and at bending of the foot and
namely of the fore foot respectively no gaping of the lattice frame
structure 13 takes place; otherwise the foot should not experience
any significant restriction in its flexibility.
[0044] The lattice frame structure 13 can flush in the bottom
region with the outer sole; however, preferably it is displaced
backwards a bit in the groove-shaped recesses in the outer sole and
midsole respectively to avoid abrasion during running
[0045] The lattice frame structure 13 is produced from a harder
material than the outer sole and midsole respectively, especially
to avoid a too strong compression and a too strong bending
respectively of the tube-like sections 5 which could cause a loss
of the connection with the bootleg.
[0046] The outer sole 11 and the midsole 12 respectively are
preferably produced from a foamed and thus damping material. Its
density lies preferably between 0.15 and 0.75 g/cm.sup.3.
[0047] However the lattice frame structure 13 and thus the
tube-like sections 5 consist preferably from a compact plastic
material, preferably from recyclable or bio-degradable material.
For the outer and midsole preferably damping materials can be taken
into consideration like EVA, PUR, PE, but also again preferably
recyclable or bio-degradable materials.
[0048] The bootleg (shoe upper part) is preferably fixed by a
zig-zag seam or is a complete moccasin. The bootleg comprises the
eye- or tube-like sections 6 which can receive the wire-like
connection element 4.
[0049] The wire-like connection element can consist of metal or
plastic material. Preferred are aramid fibres but also cords from
natural fibres which can be elongated only slightly.
[0050] The ends of the cords can be connected detachably by means
of a connection clip after threading and hooking respectively.
[0051] The connection technique is explained in the embodiment
above at which at the sole element 2 as well as at the shoe upper
part 3 tube-shaped sections 5 and 6 respectively are arranged which
form a complementary closed structure in circumferential direction
so that the connection element 4 (rope) is guided in the same which
is then not visible any more in the mounted state of the shoe
1.
[0052] But other possibilities are on hand which are not
illustrated in the embodiments but which can also be used according
to the invention when the sections 6 at the shoe upper part 3 are
designed as pure eyelets.
[0053] So, according to another non depicted solution it can be
provided that eyelets (holes) are machined in the shoe upper part 3
in the height of the tube-like sections 5 at the sole element 2.
The connection element (rope) is then threaded in and also out by
said eyelets in the shoe upper part 3 and by the tube-like sections
5 at the sole element 2.
[0054] Another solution provides that in the shoe upper part 3
recesses (elongated holes) are machined in the region in which the
sections 6 are provided according to FIG. 4. In those recesses
separate leather or plastic parts can be inserted from the inner
side which protrude from the outer surface of the shoe upper part 3
to the outer side and which form an eye- or tube-like section
through which the rope can be threaded. Thereby, the eye- or
tube-like sections 6 can be designed semi-circular in a section and
can so form again a complementary circumferential form with the
eye- or tube-like sections 5 at the sole element 2. This solution
has the advantage that no threading in and out of the cord is
necessary but only an alternating leading through of the cord from
the outer side.
[0055] A further solution provides that the shoe upper part 3 is
designed two-part, i. e. it comprises an upper part which forms the
actual shoe upper part and a bottom part--formed as a
circumferential band--which is supplied with respective loops
(tube-like sections); both bootleg parts are then connected.
