The present invention relates according to claim 1 to a shoe sole, in particular an interchangeable shoe sole, according to claim 2 to a partial shoe body and according to claims 3 and 4 each to a shoe.

Shoes are obviously one of the most widespread products, as they have always been needed and therefore also manufactured and improved.

However, so far there are no shoes that allow soles to be attached and detached multiple times in a quick, safe, easy and comfortable way. The prior art only discloses disadvantageous solutions, such as US 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 , U.S. 4,377,042 A , U.S. 4,317,294 A , 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 the production of a shoe sole. The shoe sole should preferably be able to be coupled non-destructively more than 10 or more than 50 or more than 100 or more than 500 times to a shoe part body for forming a shoe. Additionally or alternatively, the coupling should take place in a quick, safe, simple and convenient way. Additionally or alternatively, the decoupling of the shoe sole from the shoe part body should also take place 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 inner side, in particular for making contact with a shoe part body, and the tread portion preferably having a bottom surface on a second side. Having 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, the frame portion preferably having at least one carrier portion, wherein the at least one carrier portion preferably has a multiplicity of coupling elements, with at least a part, in particular a large part or the entirety, of the multiplicity of coupling elements being preferred t forms an elongate web portion or a first elongate web portion and a form-fit portion, the elongate web portion preferably being connected to or formed on the carrier portion at a first end and preferably being connected to or formed on the form-fitting portion with a second end. This embodiment is advantageous because the first elongate web and the second elongate web preferably have the same shape and dimensions over their height and can therefore be very easily introduced into corresponding coupling points of a shoe part body.

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

According to a further preferred embodiment of the present invention, the form-fit component is designed as a second elongated web or second elongated web component. The second elongate web is preferably arranged, in particular designed, 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 form 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 designed uniformly. Particularly preferably, the coupling elements have identical or substantially identical cross-sectional shapes in a sectional plane parallel to the shoe part body contact surface, wherein the cross-sectional shapes can alternatively also be partially scaled, ie the proportions of the dimensions are identical, but the absolute dimensions are changed. Alternatively, only one pair, 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 shoe part body contact surface and one or more coupling elements can be scaled.

Several coupling elements preferably have different lengths (in direction R1). This particularly preferably 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 a n -th length, wherein the first length, second length, third length, fourth length and an n-th length are different from one another. Alternatively, however, it can also be that all 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 being different from one another, in particular by are at least 0.1mm or 0.5mm or 1mm different from one another. Alternatively, however, it can also be 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 by at least 0.1mm or 0.5mm or 1mm or up to 2mm or up to 3mm or up to 5mm or up to 10mm or up to 15mm or up to 25mm different from one another.

More than 10, in particular more than 20, coupling elements according to a further preferred embodiment of the present invention are preferably provided. This embodiment is advantageous because the total load when walking is distributed over the large number of coupling elements and the shoe sole is thereby 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 extent 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 are preferably also very easy to pull out of the coupling points. The coupling of the shoe sole with a partial shoe 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, according to a further preferred embodiment of the present invention, the tread portion and the frame portion are integrally connected to one another. 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, as a result of which they have damping properties when walking and / or the second elongate web portion due to the elastic deformability of the first elongate web portion, in particular up to 2 ° or up to 5 ° or is pivotable by up to 10 ° or up to 15 °, due to the fact that when the shoe is loaded, in particular when walking or running, the coupling elements can form a form fit with the corresponding coupling points in the direction of gravity.

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 elongated web portion and a form-fitting portion, the elongated web portion being connected to the carrier portion at a first end and to a second end is formed or connected to the form-fit component. The coupling elements are particularly preferably elastically deformable, in particular pivotable, compressible and / or pullable.

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 the form-fitting connection of the shoe part body to a foot, at least in sections in an area between the foot contact surface and the sole Contact surface a connection portion is provided for receiving the shoe sole, wherein the connection portion a plurality of coupling having places, the coupling points extending from a circumferential surface of the connection part in the direction of a central region of the connection part. 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 circumferential surface is preferably interrupted exclusively by the coupling points or forms portions which are offset inward in sections, through which the coupling points are formed.

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

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

According to a further preferred embodiment of the present invention, at least a part, in particular a large part or the entirety, of the multiplicity of coupling points forms an elongate passage part and a receiving part. The elongated passage part preferably interrupts the circumferential surface of the connection part with a first end and preferably opens into the receiving part with a second end. The elongated passage portion and the receiving portion each extend (i.e. preferably per contact point) to the sole contact surface in order to each form a common passage portion-receiving portion opening for introducing a coupling element of the shoe sole. This embodiment is advantageous because the shoe sole can be securely fixed to the shoe part body even under dynamic loading via a large number of form-fitting surfaces distributed over the circumference of the shoe, without this making it difficult or impossible to decouple or remove the sole from the shoe part body.

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 part is designed as a second elongated part, the second elongated part being arranged, in particular designed, orthogonal to the elongated passage part or in sections orthogonal or inclined or in some sections inclined to the elongated passage part and at the second end of the passage part. This embodiment is advantageous because the elongated passage parts can be limited by very narrow wall parts and the forces transmitted from the shoe sole to the shoe part body or vice versa can still be safely transferred without the passage part being destroyed as a result of stress occurring when walking or running threatens.

Several coupling points preferably have different lengths (in the direction of R1). This particularly preferably 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 a n -th length, wherein the first length, second length, third length, fourth length and an n-th length are different from one another. Alternatively, however, it can also be that all the 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 being different from one another, in particular by are at least 0.1mm or 0.5mm or 1mm different from one another. Alternatively, however, it can also be 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 in each case 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 different from one another.

The present invention alternatively relates to a shoe. The alternative shoe according to the invention preferably has a shoe sole and a shoe part body, the shoe sole at least has: a tread portion and a frame portion, the tread portion having a shoe part body contact surface on a first side, in particular an inner side, for contacting a shoe part body, and the tread portion having a ground contact surface on a second side, the frame portion at least in sections, in particular mostly and preferably completely, delimits the shoe part body contact surface and wherein the frame portion at least partially, in particular mostly and preferably completely, encloses the shoe part body contact surface, the frame portion having at least one carrier portion, the at least one carrier portion having a plurality of coupling elements, wherein the shoe part body has at least one connection portion for receiving the shoe sole, the connection portion having a plurality of coupling points for interacting with the coupling elements. This solution is advantageous because the shoe part body and the shoe sole can be coupled and decoupled with one another very easily, as a result of which different soles can be arranged very easily on the shoe part body.

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 act in a non-positive manner against the first direction, in particular mostly in a non-positive manner or more than 90% in a non-positive manner or completely in a non-positive manner. This embodiment is advantageous because neither the shoe sole nor the shoe part body needs to be deformed to form a form-fitting connection and the shoe sole and the shoe part body can nevertheless be connected to one another in the direction of gravity.
