Definitions

• the invention relates to a shoe, in particular a sports shoe, with a shoe upper and a sole, wherein the sole has a connected to the shoe upper or inner part, connected to the carrier or inner part midsole and an outsole connected to the outsole.
• a damping element for a shoe, in particular for a sports shoe known which has a special construction.
• the damping element has a plurality of juxtaposed individual elements, each forming a spring and damping chamber in the manner of a piston-cylinder system.
• corresponding first and second elements are connected to each other via a connecting portion, wherein upon loading of the sole, the smaller formed element enters the larger, which forms a receiving space for this purpose.
• Such a damping element is according to said solution primarily intended to be integrated into a midsole, for which there are other models in the prior art.
• EP 0 387 505 A1 discloses a honeycomb-shaped damping element which is inserted into a receiving space in the midsole of the shoe.
• the invention is based on the invention to provide a shoe, in particular a sports shoe, which is characterized by a simpler manufacturing method, but not to dispense with the advantageous property of the previously known damping element. It should be possible in particular to keep the spring and damping behavior of the shoe influenceable.
• the midsole is formed at least over part of the B ⁇ den- occurrence surface of the shoe exclusively as a damping element having a number of juxtaposed first elements, which are substantially in a load direction in extend unloaded state of the damping element over a predetermined height and, designed as a hollow body, define a Aufhahmeraum, in the one associated second element, at least partially penetrate in the cross-section of smaller dimensions than the first element, wherein the second element extends substantially in the loading direction in the unloaded state of the damping element over a predetermined height and is arranged coaxially with the first element.
• the concept of the invention is based on the fact that the previously known damping element is used exclusively to form it - at least over a part of the surface of the midsole.
• the outsole is formed by a number of individual sole parts, wherein each sole part is arranged on the end facing away from the first element of the second element. Thereafter, the outsole is thus formed segmented; each "piston" of the piston-cylinder elements of the midsole receives part of the outsole in the area of contact with the ground.
• the shape of the individual parts of the outsole preferably corresponds to that of the second element - in a section perpendicular to the loading direction.
• the second element is also designed as a hollow body according to further development.
• the second element is designed as a completely solid or at least substantially massive part.
• the two mutually associated elements are connected to each other via an elastic connecting portion, which extends only between the first element and the second element.
• a first Element and a second element together with the connecting portion form a gas-tight chamber.
• the first and the second element usually have in a section perpendicular to the loading direction a mutually corresponding shape.
• the cross-sectional geometry of the first and the second element are formed congruent to each other, so that a matching receiving and entry space is created in the first element for the second element.
• the first element is in the unloaded state of the midsole with its axial extent substantially outside the axial extent of the second element.
• the piston-like second element is arranged in the unloaded state of the midsole axially outside of the cylinder-like first element. Only when loading the damping element in the loading direction then enters the "piston" in the "cylinder".
• the first elements may be interconnected in their lateral region or their lateral boundary walls may each be formed from a common section. Each element can also be manufactured as a separate component and then assembled.
• the first and / or second elements may have different heights at least partially in the unloaded state of the damping element.
• the unloaded state of the damping element of the connecting portion in a plane perpendicular to the loading direction may be flat or arched.
• the first element, the connecting portion and the second element are preferably formed in one piece.
• the first element, the connecting portion and the second element can be produced by a common injection molding process.
• the end remote from the second element of the first element may be connected to a sealing film. Gas-tightness of the end of the second element remote from the first element can be achieved by the outsole segment placed there.
• the material of the elements is preferably plastic, in particular thermoplastic material, in question.
• plastic in particular thermoplastic material, in question.
• the material here is preferably not translucent or not transparent.
• the material of the first element, the second element and the connecting portion, and the geometric dimensions of these parts are selected to determine the damping properties of the damping element accordingly.
• the number of adjacent or interconnected damping elements represent the midsole itself, there are only these elements that form the midsole.
• the midsole can absorb energy when loading the sole in the direction of loading and release it again when the sole is relieved.
• the lower axial end region of the first element and the upper axial end region of the second element are connected to one another via the connecting section. It is at the connecting portion - as well as the first and second element - is a part of elastic plastic material, so that when a loading force is applied to the damping element in the loading direction, a deformation takes place.
• the second element occurs like a piston in the receiving space of the first element.
• the second element facing away from the end of the first element can be connected to a sealing film, in particular welded thereto.
• a sealing film in particular welded thereto.
• the spring and damping characteristics of the damping element be adapted or selected as desired.
• Damping element - in particular the spring force on the spring travel - can thus be largely selected according to a desired course.
• FIG. 1 schematically shows a shoe, viewed from the side
• FIG. 3 shows the section AB according to FIG. 2.
• a shoe namely a sports shoe, shown only very schematically.
• the shoe has in a known manner a shoe upper 1, which is connected to a sole 2.
• the sole 2 is designed so that it expands in the front sole area 8 over a certain areal extent. In the rear sole region 9, it also expands over a defined areal extent.
• the structure of the sole 2 is shown in more detail in FIG. 2.
• the sole 2 consists of three (soles) parts, namely a carrier or inner part 2 ', a midsole 2 "and an outsole 2'".
• the support or inner part 2 ' may be an insole, an insole, a strobe sole or directly around a shaft material that forms the connection between the shoe upper 1 and the midsole 2.
• a particularly preferred embodiment provides the support or inner part 2 'as a plastic injection molded part (preferably made of EVA) and is cup-shaped.
• the carrier or inner part 2 ' is connected to the shoe upper 1.
• the compound can be produced, for example, by an injection molding process by molding the plastic material forming the carrier or inner part 2 'onto the upper part 1, which consists, for example, of textile material. Similarly, a bonding of shoe upper 1 and carrier and inner part 2 'is possible.
• the midsole 2 consists of a plurality of damping elements, which are constructed in the manner of a piston-cylinder system.At the end of the midsole 2" remote from the carrier or inner part 2 'is the Outsole 2 '"arranged, which consists of one of the number of damping elements corresponding number of sole segments 2'".
• Front sole region 8 may be configured as described, while the hindfoot region may be formed in a previously known manner.

Via a web-shaped connecting section 6, the end of the first element 3 facing away from the carrier or inner part 2 'is connected to a second element 5 which has a shape corresponding to the shape of the first element 3 - viewed in the direction R -, d.
