Description

  The present invention relates to a shoe including a shoe upper portion and a shoe sole connected to the shoe upper portion, and more particularly to a sports shoe. In this case, the shoe upper portion includes an outer surface and an inner surface, the inner surface facing the foot of the shoe wearer.

  For the general type of shoes, several embodiments are already known for designing stable shoes by minimizing the use of materials. Minimizing the use of materials not only lowers the cost of making a shoe, but also results in a lightweight shoe that is usually intended.

  In particular, for soccer shoes, the aim is to design the shoe so that the ball feel is optimized, ie the player can better feel the ball contact. Known solutions are not always satisfactory in this regard. Furthermore, there may be an adverse effect that the elasticity of the material of the shoe upper part is unnecessarily high. In fact, this can be met by a design that has the appropriate high density and thickness of the material of the upper part of the shoe, but this not only has a negative impact on the weight of the shoe, but also this In many cases, the water-absorbing capacity of the shoes is increased, and adverse effects are brought about.

  The object of the present invention is therefore to further develop a general type of shoe that, in the case of soccer shoes, gives a good ball feeling. Furthermore, the elasticity of the upper shoe material must be low for lightweight shoe designs. Finally, the aim is to reduce the water absorption capacity of the shoe.

  The solution of this object according to the invention is characterized in that a raised structure is at least partly provided on the inner surface of the upper part of the shoe. The structure includes a number of continuous closed ridges disposed on the inner surface.

  The continuous closed ridges preferably have a polygonal shape, in particular triangular, quadrangular, pentagonal or hexagonal shapes are considered. However, the continuous closed ridge can also be circular.

  The continuous closed ridge is preferably made of a plastic material. In this case, a continuous closed ridge is injected or applied onto the material of the shoe upper part by an injection molding or casting process.

  Therefore, instead of an injection molding process, a casting process can also be considered. In this case, a plasticized plastic material (eg polyurethane) is poured into the mold. Thereafter, excess material is removed and wiped off. The material of the shoe upper part (eg leather, or even another material such as synthetic leather, mesh or woven material) is placed on the mold, and then the liquid plastic ridge is placed on the bottom plate by the top plate Pressed against. Thereby, the liquid plastic material penetrates into the surface of the material of the shoe upper part, and after curing, the desired composite is produced between the shoe upper part and the raised structure.

  The continuous closed ridge includes the largest extension on the inner surface, preferably between 5 mm and 20 mm (hence the following is to be understood as the diagonal of the polygonal structure and its diameter, respectively).

  The height of the continuous closed ridge perpendicular to the inner surface is preferably between 0.5 mm and 1.5 mm.

  The inner surface inside the region surrounded by the continuous closed ridges can be provided according to a further development of the invention with a coating. In that regard, the coating preferably comprises a continuous ridge material. The coating can be separated therefrom by a certain gap from a continuous ridge, in which case the gap is preferably between 0.25 mm and 0.75 mm. The height of the coating perpendicular to the inner surface is preferably lower than the height of the continuous closed ridges, preferably 0.2 mm to 0.5 mm. However, the coating can also have the same height as the continuous ridges, which is beneficial if the coating must be used as a reinforcement.

  The upper part of the shoe can also include a tongue, and a raised structure is also provided at least partially inside the tongue.

  The shoe sole of the shoe can also be provided with a raised structure on its inside, and the raised portions of adjacent successive raised portions are preferably connected to each other in this case. The raised structure is in this case preferably free of any other sole element, in particular without the insole and insole.

  In this connection, this type of shoe sole, ie a raised structure (received on the upper side) is arranged on the inner surface of the sole, and the raised structure is in direct contact with the sole of the shoe wearer. It has been found beneficial when shoe sole elements are used that form an area. The wearer will usually actually wear each sock, but will then stand directly on the raised structure with the sock. This allows a good feeling for the ball. The raised structure is ergonomically adapted to the shape of the foot above the sole.

  The shoe is preferably a soccer shoe. The shoes can also be used beneficially in the field of golf sports.

  The raised structure preferably has walls that are rectangular in cross section. This also applies to the coatings mentioned.

  In that regard, as a further development, the outer sole of the shoe may include at least one cleat-shaped protrusion on its bottom side.

  Preferably, at least the inside of the shoe upper part is provided with a raised structure as described in the front half of the shoe. However, it may be beneficial that the raised half is not completely provided in the rear half of the upper shoe portion. In particular, it is preferred that the heel region remains free of raised structures.

  As long as the terms “top” and “bottom” are used, this relates to the position of the shoe when used intentionally and for that reason.

  Thus, the proposed solution is characterized in that the upper part of the shoe includes, on its inside, a preferably polygonal (especially hexagonal) structure designed in a raised shape. The solution may be provided against the inside of the shoe tongue. In addition, the shoe sole can also include such a raised structure on the inside, and in this case, preferably there is no insole on the raised structure. Correctly, shoe users, especially soccer players, assume that only their socks touch the ridges.

  In such a design, it is beneficial that an improved sensation for the ball and a sensation for the ground can be obtained, i.e. contact with the ball can be felt better. In that regard, the design is optionally performed without the foam structure and lining, respectively, in the upper part of the shoe and preferably also in the tongue.

  The continuous (especially polygonal) raised structure beneficially eliminates the elasticity (and elongation, respectively) from the shoe upper part, but with the known solution of lining, the adverse effect of relatively large material elongation Is brought about.

  In addition, the proposed design has a beneficial lower ability to absorb water than conventional shoes.

  In the drawings, an embodiment of the invention is shown.

It is a figure which shows shoes schematically by side view. FIG. 2 is a cross-sectional view of detail “X” according to FIG. 1 as an enlarged portion of an area of a shoe. FIG. 2 is a diagram showing “Y” according to FIG. 1 on a part of the inner surface of the upper part of the shoe. FIG. 3 is a cross-sectional view of section AB according to FIG. 2 through a section of the shoe upper part.

  In FIG. 1, a shoe 1 comprising a shoe upper part 2 and a shoe sole 3 can be seen. In that regard, the shoe upper part 2 and the shoe sole 3 are firmly connected to each other. The upper part of the shoe has an outer surface 4 and an inner surface 5, which in turn faces the foot of the shoe wearer.

  In the outline of the figure it can be seen that a raised structure 6 is arranged on the inner surface 5 of the upper shoe part 2. The inner surface 5 has a plurality of continuous closed ridges 7 arranged on the inner surface 5.

  As can be seen from FIG. 2, the raised structure 6 has a hexagonal shape in the embodiment shown, ie the raised portion 7 is designed in a hexagonal shape that is seen perpendicular to the inner surface 5. However, it should be mentioned that this is not essential and that it can also be provided for only a section of the inner surface 5.

  Depending on the space available on the inner surface 5, other shapes, in particular triangular, quadrangular and pentagonal ridges can also be provided.

  Preferably, in some cases, the raised structures of various shapes are arranged so that the inside of the shoe upper portion is completely parqueted by the raised portions.

  Further, the inner surface 5 can be partially not provided with the raised structure 6.

  Similarly, the tongue 10 of the shoe 1 comprises the raised structure 6 described on the inside.

  A preferred embodiment is shown in FIGS. Correspondingly, the substrate covering 8 of the shoe upper part 2 is made to be present inside the continuous closed ridge 7. The coating 8 maintains a gap 9 from the ridge 7 as shown in sections AB according to FIG. However, the coating agent which can be provided especially for the tongue 10 can also be applied without this gap.

  It is also possible that the coating 8 is used only in selected areas and that the empty raised structure is used in other areas of the inner surface.

  In FIG. 2 and FIG. 3, it further specifies about the magnitude | size of the protruding structure 6 and the protruding part 7, respectively.

  Accordingly, as seen in FIG. 2, the continuous closed ridge 7 is adapted to include a maximum extension E on the inner surface 5 that is between 5 mm and 20 mm.

  The height H of the continuous closed ridge 7 perpendicular to the inner surface 5 is between 0.5 mm and 1.5 mm, as can be seen from FIG.

  Most of the gap 9 has a dimension t (gap width) of 0.25 mm to 0.75 mm.

  The height h of the coating 8 is lower than the height H of the continuous closed ridge 7 and is preferably 0.2 mm to 0.5 mm.

  Also shown in FIG. 3 is a ridge width b, preferably between 0.5 mm and 1.5 mm.

  Furthermore, the thickness d which can be set to 0.5 mm to 1.5 mm also in the region of the shoe upper portion 2 is shown. Here, a single-layer material, such as leather, is preferred, on which a raised structure is directly applied by injection molding at that site.
