Description
[0001] The invention relates to a shoe, in particular to a sports
shoe, which has a shoe upper part and a sole which is connected to
the shoe upper part, wherein the shoe upper part and the sole are
connected to one another by means of a connection element.
[0002] Shoes of the generic kind are produced often in such a way
that the shoe upper part is connected with the sole by sewing.
Alternatively or additively, also glueing connections are known
which should guarantee watertightness. The quality of the
connection decides essentially if the shoe is usable
permanently.
[0003] Especially with respect to the watertightness of the shoe
also more elaborate solutions became known to establish the
connection between the shoe upper part and the sole. Here, it is
detrimental that the required expenditures are sometimes
significant so that the shoe is respectively expensive in its
production.
[0004] It is the object of the invention to further develop a shoe
of the generic kind so that the connection between the shoe upper
part and the sole can be simplified, wherein however a high degree
of stability of the connection is guaranteed between the parts.
Furthermore, the connection between the shoe upper part and the
sole should also be waterproof The connection should be producible
in an easy manner with respect to manufacturing so that a
cost-efficient production of the shoe becomes possible.
[0005] The solution of this object by the invention is
characterized in that the connection element is a longitudinally
extending, profiled moulded part that has an upper stripe-shaped
section and a lower fork-shaped section which has two fork
sections, wherein the shoe upper part has a stripe-shaped upper
part section in its region that adjoins the sole, which
stripe-shaped upper part section is connected to the strip-shaped
section of the connecting element, and wherein the sole has a
stripe-shaped sole section in its region that adjoins the shoe
upper part, which strip-shaped sole section extends between the two
fork sections and is connected to at least one of the fork
sections.
[0006] The fork sections are preferably arranged substantially
parallel to another.
[0007] The connection between the stripe-shaped upper part section
and the upper stripe-shaped section of the connection element is
preferably established by a seam.
[0008] The connection between the stripe-shaped sole section and at
least one of the fork sections is preferably established by a
form-fit connection. Thereby, the form-fit connection can comprises
at least one nose-shaped projection at the stripe-shaped sole
section (or at at least one of the fork sections) and at least one
hook section at at least one of the fork sections (or at the
stripe-shaped sole section), wherein the nose-shaped projection and
the hook section are designed congruent to another. Thereby, it is
preferred that a single nose-shaped projection is arranged or
provided at the stripe-shaped sole section and a single hook
section is arranged or provided at one of the fork section.
[0009] The connection between the stripe-shaped sole section and at
least one of the fork sections can also be established by a
material bonded connection. Thereby, the material bonded connection
is preferably a welding connection, especially a laser welding
connection.
[0010] It is specifically preferred that the connection between the
stripe-shaped sole section and at least one of the fork sections is
established by a form-fit connection as well as by a material
bonded connection.
[0011] The connection element is preferably an extruded plastic
profile. The plastic material of the connection element is
preferably transparent.
[0012] The sole can comprise at least one sole part, wherein the
shoe upper part comprises at least one cutout which is arranged in
the region which is facing the ground, which size and shape
corresponds to the sole part in its contact region with the shoe
upper part; thereby, the at least one sole part can be inserted
into the at least one cutout and can be connected with the shoe
upper part by means of the connection element.
[0013] The at least one sole part can be designed as a shell-shaped
structure; thereby, this is primarily a sole part in the heel
region of the shoe.
[0014] Thereby, one sole part can be arranged in the rearfoot
region and one sole part can be arranged in the forefoot region.
The shoe upper part is preferably designed between the two sole
parts continuously and seam-less.
[0015] As far as the terms "top" and "bottom" respectively are used
this refers to the position of the shoe when it is in normal use
and is resting on the ground.
[0016] The connection element in the form of the plastic profile is
thus snapped into a protrusion of the sole element which is to be
attached and is then connected with the sole element by means of
laser welding. The plastic profile is then sewed at the shoe upper
part via a plane web section of the plastic profile.
[0017] A simple and cost effective producible composite between the
shoe upper part and the sole results which has a high stability and
is substantially tight.
[0018] In the drawing an embodiment of the invention is depicted.
It shows:
[0019] FIG. 1 in perspective view a shoe with a shoe upper part and
two sole parts which are fixed at the shoe upper part,
[0020] FIG. 2 in perspective view the shoe upper part in a view
transverse from the bottom, wherein the sole parts are
detached,
[0021] FIG. 3 in perspective view one of the sole parts of the shoe
and
[0022] FIG. 4 a cross section through the finished shoe according
to the section C-D according to FIG. 1.
[0023] In FIGS. 1 to 3 at first a possible embodiment of an example
of the basic design of the shoe 1 with a shoe upper part 2 and a
sole 3 is depicted. The shoe upper part 2 has two cutouts 15 and 16
in its bottom region, in which the sole parts 3' and 3'' are
inserted and fixed there.
[0024] The making of the connection between shoe upper part 2 and
sole 3 respectively sole parts 3', 3'' is apparent in detail from
the sectional view according the FIG. 4 in detail. The outer region
is marked with A, the inner of the shoe with I.
[0025] The shoe upper part 2 is provided with a stripe-shaped upper
part section 9 in the region which adjoins to the sole 3. Also the
sole 3 comprises a stripe-shaped sole section 10 in the region
which is facing the shoe upper part 2 (see FIG. 3). The two
stripe-shaped sections 9 and 10 are connected with another by means
of a connection element 4 which is an extruded plastic profile and
which has the cross sectional shape which is apparent from FIG.
4.
[0026] The connection element 4 comprises an upper stripe-shaped
section 5 as well as a lower fork-shaped section 6. The fork-shaped
section 6 comprises two fork sections 7 and 8 which nm
substantially parallel to another and defined a receiving space
between them.
[0027] The connection between the stripe-shaped upper part section
9 and the upper stripe-shaped section 5 of the connection element 4
occurs by sewing. A seam 11 is depicted which connects the two
mentioned parts.
[0028] However, the connection between the connection element 4 and
the stripe-shaped sole section 10 is established by a combined
form-fit and material bonded connection.
[0029] For this, the stripe-shaped sole section 10 comprises a
nose-shaped projection 12. This is also depicted in FIG. 4. It is
directed to the outer side of the shoe, while the stripe-shaped
sole section 10 is provided in a straight respectively flat manner
at the other side, i. e. at the side which is facing the inner of
the shoe.
[0030] One of the two fork sections, namely the fork-section 7, is
provided with a hook section 13. Hook section 13 and projection 12
are designed congruent to another, i. e. in the state in which the
parts are stuck together an arrangement is given as depicted in
FIG. 4. The hook section 13 grabs the projection 12 in a form-fit
manner and thus holds the sole 3 firmly at the connection element
4.
[0031] As certainly this form-fit connection alone is normally not
firm enough, an additional material bonded connection is created
after sticking together of the parts 3 and 4. This occurs presently
by a laser welding of the materials of connection element 4 and
sole section 10.
[0032] In FIG. 4 a laser head 17 is denoted by which a focussed
laser beam is directed onto the location where the desired welding
seam 14 should be created. After a short melting of the material of
connection element 4 and sole section 10 a firm mechanical bond as
well as a waterproof connection result between the parts.
[0033] The use of thermoplastic materials for the sole 3 and the
connection element 4 allows in a simple manner the material bonding
connection.
[0034] However, also a glueing connection can be taken into account
between the mentioned parts.
