Shoes are obviously one of the most common products as they have always been needed and thus also manufactured and improved.

However, to date there have been no shoes that allow multiple attachment and detachment of soles in a quick, safe, simple and comfortable manner. The prior art only discloses disadvantageous solutions, such as U.S. 7,254,905 B2 , CN 2747926 Y , FR 2 924 311 A1 , ES 1 261 685 U , DE 35 26 298 A1 , CN 202311514 U , CN 205106544 U , DE 201 15 293 U1 , KR 2019-0048031 A , CN 206150576 U , US 4,377,042A , US 4,317,294A , WO 2006/031005 A1 or DE 26 52 071 A1 .

It is therefore the object of the present invention to provide an advantageous shoe sole, an advantageous partial shoe body, an advantageous shoe, control data for the advantageous production of an advantageous shoe sole and an advantageous method for producing a shoe sole. The shoe sole should preferably be able to be coupled non-destructively to a shoe part body more than 10 or more than 50 or more than 100 or more than 500 times to form a shoe. In addition or as an alternative, the coupling should take place in a quick, safe, simple and convenient manner. In addition or as an alternative, the shoe sole should also be decoupled from the shoe part body at least quickly and easily.

The aforementioned object is achieved according to the invention by a shoe sole according to claim 1. The shoe sole preferably has at least: a tread portion and a frame portion, the tread portion preferably having a shoe part body contact surface on a first side, in particular an inside, in particular for contacting a shoe part body, and the tread portion preferably having a ground contact surface on a second side has contact surface, wherein the frame portion preferably at least partially, in particular mostly and preferably completely, delimits the shoe part body contact surface and wherein the frame portion preferably at least partially, in particular mostly and preferably completely, encloses the shoe part body contact surface, wherein the frame portion preferably has at least one support portion, wherein the at least one carrier portion preferably has a plurality of coupling elements, wherein at least a part, in particular a large part or the entirety, of the plurality of coupling elements preferably forms an elongate web portion or a first elongate web portion and a form-fitting portion, the elongate web portion preferably having a first end is connected to the support portion or formed thereon and is preferably connected to a second end with the form-fitting portion or formed thereon. This embodiment is advantageous because the first elongate bar and the second elongate bar preferably have the same shape and dimensions over their height and can therefore be introduced very easily into corresponding coupling points of a shoe part body.

According to a further preferred embodiment of the present invention, the support portion extends in a first direction relative to the shoe part body contact surface. The first direction preferably extends relative to the shoe part body contact surface at an angle of between 60° and 120°, in particular at an angle of between 80° and 100° or at an angle of between 85° and 95°, in particular at an angle of 90°. This configuration is advantageous because the coupling elements can thereby connect the support portion and the contact surface of the shoe part body with one another in a materially bonded manner, thereby increasing the overall stability of the shoe sole. Alternatively, individual or all coupling elements can be formed exclusively on the carrier part in a materially bonded manner and only interact with the shoe part body contact surface in a contacting manner or rest on it.

According to a further preferred embodiment of the present invention, the form-fitting portion is designed as a second elongate web or second elongate web portion. The second elongate web is preferably arranged, in particular formed, orthogonally to the first elongate web at the second end of the first elongate web. This embodiment is advantageous because the second elongate web forms a positive fit with the corresponding coupling point in the outward direction (in the direction of the circumference).

The entire shoe sole according to the invention is preferably a one-piece polymer body. The coupling elements are preferably all of the same design. Particularly preferably, the coupling elements have identical or substantially identical ones in a sectional plane parallel to the contact surface of the shoe part body Cross-sectional shapes, the cross-sectional shapes can alternatively also be partly scaled, ie the ratios of the dimensions are identical, but the absolute dimensions changed. Alternatively, only a few, in particular at least 4 or 8 or 12 or up to 12, coupling elements can have identical cross sections in a plane parallel to the contact surface of the shoe part body and one or more coupling elements can be scaled.

A plurality of coupling elements preferably have different lengths (in direction R1). Particularly preferably, this means that one or more coupling elements have a first length and one or more coupling elements have a second length and one or more coupling elements have a third length and one or more coupling elements have a fourth length and/or one or more coupling elements have an nth Have length, wherein the first length, second length, third length, fourth length and an nth length are different from each other. Alternatively, however, it can also be the case that all the coupling elements have the same length or that only some of the coupling elements have a first length and another part of the coupling elements has a second length, the first length and the second length differing from one another, in particular by differ from each other by at least 0.1 mm or 0.5 mm or 1 mm. Alternatively, however, it can also be the case that only some of the coupling elements have a first length and another part of the coupling elements has a second length and another part has a third length, the first length and the second length and the third length being different from one another are, in particular each differ from one another by at least 0.1 mm or 0.5 mm or 1 mm or up to 2 mm or up to 3 mm or up to 5 mm or up to 10 mm or up to 15 mm or up to 25 mm.

More than 10, in particular more than 20, coupling elements are preferably provided according to a further preferred embodiment of the present invention. This embodiment is advantageous because the total load when walking is distributed over the large number of coupling elements and the shoe sole is thus held very securely on the shoe part body.

According to a further preferred embodiment of the present invention, the majority of the coupling elements have the same cross-sectional shape and/or are arranged, in particular formed, at the same distance from the next coupling element. The cross-sectional shape of several, in particular the majority or all, of the coupling elements orthogonal to the first direction and along at least 50% of the length or at least 75% of the length or at least 90% of the length or 100% of the length of the coupling elements is according to a further preferred embodiment of the present invention uniform or identical in the direction of extension of the first direction. This embodiment is advantageous because it allows the coupling elements to be pushed very easily into the coupling points of a shoe part body. The coupling elements can also be pulled out of the coupling points very easily. The coupling of the shoe sole to a shoe part body can thus be carried out very quickly and preferably intuitively.

According to a further preferred embodiment of the present invention, the tread portion and the frame portion directly adjoin one another. Additionally or alternatively, the tread portion and the frame portion are connected to one another in one piece according to a further preferred embodiment of the present invention. Additionally or alternatively, the shoe sole is an injection molded part, in particular a one-piece injection molded part and/or a one-component injection molded part (1k) or a multi-component injection molded part (2k or nk). This embodiment is advantageous because the coupling elements are designed to be elastically deformable, which means that they have dampening properties when walking and/or the second elongated web portion due to the elastic deformability of the first elongated web portion, in particular up to 2° or up to 5° or up to 10° or up to 15°, can be pivoted by the coupling elements being able to form a form fit with the corresponding coupling points in the direction of gravity when the shoe is loaded, in particular when walking or running.

According to a further preferred embodiment of the present invention, at least a part, in particular a large part or the entirety, of the plurality of coupling elements forms an elongate web portion and a form-fitting portion, the elongate web portion being connected to the support portion at a first end and to a second end is formed or connected to the form-fitting portion. The coupling elements are particularly preferably elastically deformable, in particular pivotable, compressible and/or retractable.

The present invention also relates to a shoe part body. The shoe part body preferably has at least: a foot contact surface and a sole contact surface spaced apart from the foot contact surface and at least one form-fitting device for form-fitting attachment of the shoe part body to a foot, at least in sections in one area between the foot contact surface and the sole contact surface there is a connection portion for receiving the shoe sole, the connection portion having a large number of coupling points, the coupling points extending from a peripheral surface of the connection portion in the direction of a central area of the connection portion. In the context of the present invention, a foot-side contact surface can also be understood as a foot-contact surface, ie the foot-contact surface is arranged or formed closer to a foot-receiving area than the sole-contact surface. The peripheral surface is preferably only interrupted by the coupling points or forms parts offset inwards in sections, through which the coupling points are formed.

This solution is advantageous because the coupling points are at least mostly outside the center of the foot contact surface and thus neither the stability of the shoe when walking or running nor the comfort is impaired.

In the context of the present invention, a shoe without a sole can be understood as a shoe part body.

According to a further preferred embodiment of the present invention, at least a part, in particular a large part or the entirety, of the plurality of coupling points forms an elongate passage portion and a receiving portion. The elongate passage portion preferably interrupts the peripheral surface of the connection portion with a first end and preferably opens with a second end in the receiving portion. The elongated passage portion and the receiving portion each extend (i.e. preferably per contact point) to the sole contact surface to form a common passage portion-receiving portion opening for insertion of a respective coupling element of the shoe sole. This embodiment is advantageous because the shoe sole can be securely fixed to the shoe part body via a large number of form-fitting surfaces distributed over the circumference of the shoe, even under dynamic loading, without the decoupling or pulling off of the sole from the shoe part body being made more difficult or prevented.

The circumferential surface can also be divided into a plurality, in particular more than 5 or more than 10 or exactly 10 or up to 10 or more than 15 or exactly 15 or up to 15 or more than 20 or exactly 20 or up to 20 Partial surfaces are referred to. In a state coupled to the sole, the partial surfaces are preferably in contact with corresponding surface portions of the carrier portion.

According to a further preferred embodiment of the present invention, the receiving portion is designed as a second elongate portion, the second elongate portion being orthogonal to the elongate passage portion or orthogonal in sections or inclined or inclined in sections to the elongate passage portion and arranged, in particular formed, at the second end of the passage portion. This embodiment is advantageous because the elongated passage portions can each be delimited by very narrow wall portions and yet the forces transmitted from the shoe sole to the shoe part body or vice versa can be safely transmitted without the passage portion being destroyed as a result of a load occurring when walking or running threatens.

A number of coupling points preferably have different lengths (in direction R1). Particularly preferably, this means that one or more coupling points have a first length and one or more coupling points have a second length and one or more coupling points have a third length and one or more coupling points have a fourth length and/or one or more coupling points have an nth Have length, wherein the first length, second length, third length, fourth length and an nth length are different from each other. Alternatively, however, it can also be the case that all coupling points have the same length or that only some of the coupling points have a first length and another part of the coupling points has a second length, the first length and the second length differing from one another, in particular by at least 0.1mm or 0.5mm or 1mm differ from each other. Alternatively, however, it can also be the case that only some of the coupling points have a first length and another part of the coupling points has a second length and another part has a third length, the first length and the second length and the third length being different from one another are, in particular each differ from one another by at least 0.1 mm or 0.5 mm or 1 mm or up to 2 mm or up to 3 mm or up to 5 mm or up to 10 mm or up to 15 mm or up to 25 mm.

This solution is advantageous because the shoe part body and the shoe sole can be coupled and uncoupled to one another very easily, as a result of which different soles can be arranged on the shoe part body very easily.

According to a further preferred embodiment of the present invention, the coupling points and the coupling elements for coupling the shoe sole can be moved relative to one another on the shoe part body. In a coupled state, the coupling elements and the coupling points interact in a force-locking manner counter to the first direction, in particular predominantly in a force-locking manner or more than 90% in a force-locking manner or completely in a force-locking manner. This embodiment is advantageous because neither the shoe sole nor the shoe part body has to be deformed in order to form a positive connection and the shoe sole and the shoe part body can still be connected to one another in the direction of gravity.

For example, a shoe sole 1 can be produced according to the invention, which has at least: a tread portion 2 and a frame portion 4, wherein the tread portion 2 has a shoe part body contact surface 8, in particular for contacting a shoe part body 10, on a first side, in particular an inner side, and wherein the tread portion 2 has a ground contact surface 14 on a second side, the frame portion 4 delimiting the shoe part body contact surface 8 at least in sections, in particular mostly and preferably completely, and the frame portion 4 at least in sections, in particular mostly and preferably completely, delimiting the shoe part body encloses contact surface 8, wherein the frame portion 4 has at least one carrier portion 16, wherein the at least one carrier portion 16 has a plurality of coupling elements 18, wherein at least a portion, in particular a majority or all, of the plurality of coupling elements 18 has a first elongate web portion 20 and forms a form-fitting portion 22, wherein the first elongated web portion (20) is connected to the carrier portion 16 at a first end 24 and to the form-fitting portion 22 at a second end 26, wherein the coupling elements 18 are elastically deformable, the coupling elements 18 being outside of a central portion of the shoe part body contact surface 8 and wherein the central portion forms more than 40% or more than 50% or more than 60% or more than 70% of the total area of the shoe part body contact surface 8 .

7a shows purely schematically, using an example of a shoe sole 1, that coupling elements 18 of different sizes, in particular widths, can be provided or formed.

7b 1 shows purely schematically, using an example of a shoe sole 1, that coupling elements 18 can be provided or designed with different geometries.

7c 1 shows purely schematically, using an example of a shoe sole 1, that coupling elements 18 can be designed or formed differently in different areas of the shoe sole.

7d shows purely schematically, using an example of a shoe sole 1, that the coupling elements 18 can be configured in groups, with the coupling elements 18 of a group preferably being at a distance from the next coupling element 18 in the group that is less than the distance between the group and another coupling element (the in the circumferential direction of the shoe sole 1 on the one hand or on the other hand of the group is the closest coupling element 18), in particular a coupling element of a further group of coupling elements. A shoe sole can preferably have a large number, in particular more than 2 or preferably more than 3 or most preferably more than 5 groups of coupling elements 18 .

The 7e shows that the number of coupling elements 18 can vary depending on the proportion of the sole. For example, a larger or smaller number of coupling elements 18 can be formed in the forefoot area than in the heel area. The forefoot area is preferably the front area of the sole and the heel area is preferably the rear area of the sole. The front area of the sole preferably extends from the front end (in the area of the tens) over 20% or over 30% or over 40% or over 50% or over 60% of the length of the shoe sole 1. The rear area of the sole extends preferably over the remaining portion of the shoe sole 1.

The in the 7a until 7e The variants shown serve to illustrate that different combinations and/or shapes and/or arrangements are possible and the variants shown are therefore also possible in combination with one another.

The 8a until 8h show purely exemplary shapes for coupling points 18, such as those in 7a until 7e shoe soles 1 shown can be configured additionally or alternatively.
