Abstract
In a shoe sole having a shoe sole layer in which a plurality of supporting means arranged in a plurality of channels extending parallel to one another over the sole surface are introduced, the shoe sole layer and the supporting means should be easy to produce and, as a result of their interaction, should enable an optimised supporting or cushioning effect to be achieved in local regions of the sole surface. This is achieved in that the supporting means are formed in at least two parts from parts that can be separated from one another, more particularly from a shell and at least one core, and that the plurality of supporting means are inserted into the plurality of channels in the vertical direction (V), perpendicularly in relation to the sole longitudinal axis (L), in a manner such that they are retained with a form fit, the supporting means at least partially filling out the channels and the supporting means having, depending on their position on the shoe sole layer, different supporting effects along the sole surface due to their total hardness.
Description
- The present invention describes a shoe sole having a shoe sole layer, in which a plurality of supporting means arranged in a plurality of channels extending parallel to one another over the sole surface are introduced.
- In the past, the soles of shoes were further developed such that primarily the cushioning properties of the shoe sole or individual shoe sole layers were matched to the usage purpose of the shoe and the size and weight of the wearer of the shoe. In all such developments, it should be ensured that the stability of the entire shoe sole is not reduced. This is sometimes the problem when shoe soles are provided with massage effects, which is not the goal here.
- As known, for example, from CN107440218, shoe sole layers have been developed that have various cushioning means in the profile thereof. These cushioning means are designed as cushion-like or spring-like structures which are incorporated into recesses or cavities during the manufacturing process of the shoe sole layer. With resilient cushioning means, a desired affect can be achieved at defined points such that, for example, pressure points on the sole of the shoe wearer's foot can be prevented during sport activities. When a wearer is especially heavy, CN204908160 also discloses shoes with shoe sole layers having an improved shock absorption. Within the shoe sole layer, there are likewise cavities recessed in which, in turn, cushion-like or spring-like cushioning means are placed.
- The aforementioned ideas appear to be quite vague as a whole, and it is difficult to adapt the commercial mass-production of shoes to the personal requirements of various shoe wearers. It is unclear precisely how an adaptation of the shock absorption properties of the shoe sole layer is supposed to be adjustable, in a reproducible manner, to match to the weight or the usage purpose of the shoe. It is not sufficiently precisely possible in this case to implement the precise adjustment of the cushioning properties. Even if the number of cavities flatly distributed on the sole surface is greatly increased, the adjustment options are very limited. It is unlikely that cushioning means with a sufficiently high density can be flatly distributed on the sole surface. It is certainly difficult for simple manufacturing of such shoe sole layers since the adaptation of the cushioning means in differently sized cavities in the shoe sole layer is associated with a great deal of complexity.
- The object of the present invention is to obtain a shoe sole layer of a shoe sole with a plurality of supporting means, in which the shoe sole layer and the supporting means, due to the interaction thereof, are simple to manufacture, and an optimized supporting or cushioning effect is achieved in local regions of a sole surface.
- It should be possible to achieve different cushioning specifications of the resulting shoe sole, in which the shoe still has a sufficiently stable shoe sole layer. In order to achieve this, the supporting means are placed in the shoe sole layer with a form-fit.
- To achieve the object, the shape of the shoe sole layer or the arrangement and shape of the cavities, matched to the desired shoe size, always have the same structure, in which the selection of the supporting means to be used is different, matched to the cushioning properties to be achieved.
- Variations of combinations of features or slight adaptations of the invention are stated in the detailed description, depicted in the figures, and included in the dependent claims.
- The subject matter of the invention is described in detail in the following using the appended drawings. Necessary features, details, and advantages of the invention result from said description as follows.
- The following is shown:
-
FIG. 1 a perspective, exploded view of a shoe sole having a plurality of supporting means before insertion into a plurality of channels in a shoe sole layer. -
FIG. 2 a perspective view of various filled supporting means, in which, using an example here, cores with cruciform cross-sectional surfaces are selected. -
FIG. 3 a perspective view of a shoe sole with the shoe sole layer, in which the plurality of supporting means is partly arranged extending away from a sole surface. - In this case, a
shoe sole layer 10 is shown as a part of ashoe sole 1. Theshoe sole 1 itself forms a part of a shoe, which is not shown here. The resultingshoe sole layer 10 obtains an adjustable option, finely meshed along the sole surface, for defining the local cushioning properties under discussion here. Specifically defined cushioning properties can be achieved along various regions, in the ball of the foot, in the heel region, in the outer edge region of the foot, or along the longitudinal arch region of the sole surface, which properties are correspondingly scaled for all shoe sizes or sole sizes. These regions are indicated, in a delimited manner, by dashed lines inFIG. 3 . - In the ready-to-use state, the
shoe sole layer 10 is equipped, at the base, with anoutsole layer 11 having aprofile 110 of theoutsole layer 11. Theoutsole layer 11 in this case protrudes up to the height of anupper end surface 100. A cover sole and an inner sole or brand sole is typically arranged on theupper end surface 100 of theshoe sole layer 10 before theentire shoe sole 1 is ready for use. For the sake of clarity, these various soles are not shown in this case but could also be an optional part of theshoe sole layer 10. -
Channels 101 extending parallel to one another over the sole surface are recessed in the shoesole layer 10. Thechannels 101 are arranged in several rows ofchannels 101 parallel to the longitudinal direction L and in several columns ofchannels 101 parallel to the transverse direction Q of theshoe sole layer 10. - The extension direction of the
channels 101 is oriented in a vertical direction V, perpendicular to the longitudinal direction L and transverse direction Q, respectively. In this case, thechannels 101 extend from the foot-facing,upper end surface 100 of theshoe sole layer 10, in the direction of theshoe sole layer 11, perpendicular to the longitudinal direction L and to the transverse direction Q of theshoe sole layer 10. A honeycomb-like structure is formed by the orientation and plurality ofchannels 101Channel walls 102, which separate the interior of the channels from one another, are arranged betweenadjacent channels 101. Thechannels 101 preferably all extend parallel to one another, in which the depth of thechannels 101 may differ due to the different heights of theshoe sole layer 10. This is shown inFIG. 1 , in which the depths of thechannels 101 are greater in the vertical direction V in the heel region than in the region of the ball of the foot of theshoe sole layer 10. - The cross-sectional surface of the
channels 101 in this case is particularly respectively cruciform, in which other flat geometric figures, such as polygons like rectangles, squares, triangles, hexagons, or even stars can be selected. - The cross-sectional surface in the course of the
channels 101 preferably remains constant. This results in the shape of thechannels 101 in the form of blind holes in the shoesole layer 10, which are open toward theupper end surface 100. - Several supporting
means 2, preferably designed in multiple parts respectively, are then inserted, which are introduced into the plurality ofchannels 101 in the vertical direction V. The supporting means 2 fill out thechannels 101 at least partially. Thus, the supportingmeans 2 are retained in thechannels 101 with a form-fit. Because the weight force of the shoe wearer is applied in the vertical direction V in use, the supportingmeans 2 are retained in a captive manner. The supportingmeans 2 should have different hardnesses so that the regions of the shoesole layer 10 have different cushioning effects depending on the placement of the supportingmeans 2. - The supporting
means 2 are produced in at least two parts from parts which can be separated from one another. In this case, the two-part variant is shown with ashell 20 and at least onecore 21 and explained in more detail. Theshell 20 in this case is equipped with a cruciform cross-sectional surface, in which an inner shell contour 200 is recessed. The cross-sectional surface of theshell 20 corresponds to the cross-sectional surface of thechannels 101 such that a form-fit connection is possible. In the recessed area of theshell 20, thecore 21 is introduced in the longitudinal axis of the shell. To this end, thecore 21 is provided with a correspondingouter core contour 210. The connection between thecore 21 and theshell 20 is also a form-fit connection. - Due to the material used for the
shell 20, the shell height H. and the inner shell contour 200, theshell 20 has an adjustable hardness. The same applies to thecore 21 due to the material thereof, the core height K, and theouter core contour 210. A total hardness of each supportingmeans 2 is thereby achieved. - For example, differently inserted
cores 21 with different hardnesses or anempty shell 20 are shown inFIG. 2 . Supporting means 2 with various levels of hardness and thus cushioning can be achieved through the correct selection ofsuitable shells 20 andcores 21. Optionally, thecore 21 of some supportingmeans 2 can be inserted partially protruding from theshell 20. - Preferably however, the core height K of the
core 21 is selected to be the same size as the shell height H of theshell 20 of the supportingmeans 2, and thecores 21 are inserted into the inner shell contour 200 flush with the shell height H. - In practice, the
shell 20 tends to be designed softer than the at least onecore 21 such that the hardness of theshell 20 is respectively less than the hardness of the incorporated at least onecore 21. - The desired supporting effect or cushioning effect can specifically be achieved locally along the sole surface through the design of the individual parts of the supporting
means 2 and depending on the placement in the course of theshoe sole layer 10. - In the examples shown of the supporting
means 2, the shape of theouter core contour 210 or the cross-sectional surface of thecore 21 is a cross. This cross-sectional surface has proven to be especially suitable; however, other flat geometric shapes could also be chosen. - In the finished state of the
shoe sole layer 10, the supportingmeans 2 are introduced into the providedchannels 101. In this case, the shell heights H of theshell 20 are selected such that the supportingelements 2 extend slightly away from the foot-facing,upper end surface 100 of theshoe sole layer 10. Thus, the end face of theshell 20 is not selected to be flush with theupper end surface 100 of theshoe sole layer 10. The core heights K in this case are selected to be the same size, just as the shell heights H or thecores 21 are introduced such that thecores 21 and theshells 20 thereof terminate flush on one side. - As shown in
FIG. 3 , there are sections, for example in the region of the ball of the foot, in which thechannels 101 are filled with identical supporting means 2, comprisingidentical shells 20 andcores 21, with a defined total hardness. In other regions, for example in the heel region, the columns ofchannels 101 are filled with identical supporting means 2 parallel to the transverse direction Q, which have, however, a total hardness different from the supportingmeans 2 in the region of the ball of the foot. - For example, region C is indicated, into which supporting means 2 with
different shells 20,cores 21, and/or hardnesses ofshells 20 and/orcores 21 are introduced in theadjacent channels 101. Therefore, a locally very precise adjustment of the cushioning effect can be achieved along the sole surface. Depending on the diameter of thechannels 101 and of the supportingmeans 2, a high density of supportingmeans 2 can be achieved along theupper end surface 100 such that a very precise adjustment can be achieved in the local cushioning effect. - Since the
shells 20 andcores 21 are produced from plastics, preferably from polymers and elastomers, the hardness measurement is implemented using a Shore durometer. Preferably, the Shore A hardnesses are between 20 to 30 and 40 to 50. - The
shoe sole layer 10 with recessedchannels 101 can be produced in a plastic injection-molding process or, for example, using a 3D printer. The same applies to theshell 20 and thecore 21 of the supportingmeans 2. Any plastic materials correspondingly processable can be suitable for this. Optionally, thecores 21 in the inner shell contour 200 can also be attached using an adhesive bond, which is achieved, for example, by means of an adhesive. - It would also be possible to insert more than one
core 21 into theshell 20 of each supportingmeans 2. - Since the supporting
means 2 are arranged flatly distributed in the plane of the sole surface in a plurality, the cushioning properties of theshoe sole layer 10 can be adjusted very precisely and locally. In this case, directlyadjacent channels 101 can be provided with different supporting means 2. The plurality of supportingmeans 2 can be inserted into the correspondingchannels 101 completely in layers. The individual supporting means 2 are possibly connected to one another via predetermined breaking-point bridges. In the 3D printing process, theshoe sole layer 10 including thechannels 101 and the supportingmeans 2 can also be printed simultaneously. Accordingly, theshoe sole layer 10 according to any of the claims is produced completely by printing in a 3D printing process by means of a 3D printer. -

2. The shoe sole of claim 1 , wherein the shell is designed softer than the at least one core.
3. The shoe sole of claim 1 , wherein an outer core contour of the at least one core is adapted to the inner shell contour of the shell such that the at least one core can be inserted in a manner such that it is retained in the shell with a form-fit.
4. The shoe sole of claim 3 , wherein the at least one core is attached in the inner shell contour with an adhesive bond.
5. The shoe sole of claim 1 , wherein the hardness of the at least one core of the supporting means is softer in the region of the balls of the foot of the shoe sole layer than the hardness of the at least one core of the supporting means in the region of the heel of the shoe sole layer.
6. The shoe sole of claim 1 , wherein a shell height (H) of the shell is selected so that the supporting elements protrude away from a foot-facing, upper end surface of the shoe sole layer in the vertical direction (V) of the shoe sole layer.
7. The shoe sole of claim 1 , wherein the at least one core protrudes away from the inner shell contours of the shells.
8. The shoe sole of claim 6 , wherein a core height (K) corresponds to a shell height (H) of the supporting means.
9. The shoe sole of claim 1 , wherein the plurality of channels is formed as a blind hole in the shoe sole layer from which a foot-facing, upper end surface of the shoe sole layer extends to an outsole layer connected to the shoe sole layer.
10. The shoe sole of claim 3 , wherein the outer core contour of the at least one core represents a cross.
11. The shoe sole of claim 1 , wherein the plurality of channels extends parallel to one other in the vertical direction (V) of the shoe sole layer, from which a foot-facing, upper end surface of the shoe sole layer is arranged, forming a honeycomb-like structure in the direction of an outsole layer perpendicular to the longitudinal direction (L) of the shoe sole layer, and adjacent channels are separated from one another by channel walls.
