Description

The present invention relates to a shoe or Outsole, according to the preamble of claim 1.

The present invention further relates to a shoe, according to the preamble of claim 12, with such Sole.

The design of shoe or outsoles was and is a Problem that people have always been concerned with have and keep busy. In the field of modern shoe manufacturing a line has formed in the finished soles are used that are suitable after manufacture with the other elements of a shoe (Insole, upper, etc.) without additional processing steps to be able to be processed.

DE GM 90 14 122.9 is a finished sole for shoes known, which has a sole surface in which at the Insole projecting inside of the sole Elements, in the form of webs, are arranged perpendicular to the Longitudinal direction (longitudinal axis of the sole) run. In the heel area and partly in the intermediate area between the heel area and the ball of the foot is in the area of the longitudinal center axis the sole in these areas in the longitudinal axis direction longitudinal bar provided. The crossbars run from the tip of the sole to the end of the Heel area parallel to each other and are attached to the respective End side delimited by an edge.

From DE OS 25 30 403 is a sole for high-heeled shoes known, in from the sole surface inwards Insole protruding elements in the form of a rectangular Grid are provided, the web-like edges the grid is diagonal, i.e. an angle of approx. Form 45 degrees to the longitudinal axis of the sole.

From EP-185 781 a shoe sole made of plastic or Rubber known in the heel and ball area a diamond-shaped grid is provided, the grid webs run diagonally to the longitudinal axis of the shoe and forward are inclined to cushion and dampen of the foot when walking.

It has long been known in medicine that the most natural and healthiest form of running barefoot is. It is important that the foot on the sole when walking in a natural way from the heel to the Toe rolls and a certain pressure distribution on the The sole of the foot is reached, which is essentially a linear longitudinal pressure peak line having.

All soles of the above mentioned publications of the stand However, the technology has the disadvantage that due to the design of the inwardly projecting elements on the one hand and the design of the underside of the sole surface on the other hand a running that is the optimal medical Meets requirements, is not made possible.

The present invention is therefore based on the object a shoe or outsole made of resilient material to improve the type mentioned in such a way that a walking essentially corresponding to walking barefoot Shoe is made possible.

The present invention further relates to a shoe, which has such a sole.

This object is achieved in that the protruding elements at the bottom essentially transverse to the longitudinal direction of the sole or longitudinal axis, Broken webs are parallel to the outer contour of the sole at least one longitudinal rib on the underside of the sole at least is provided along the outside of the sole, which is at a distance from the outer sole contour, the significantly less than half the sole width in the heel area and that between the ball of the foot and the Heel area a sickle-shaped filling up the grid Reinforcement area is provided, which extends from the inside of the sole extends in the direction of the longitudinal axis of the sole.

With this configuration, a rolling behavior of the sole achieved that a natural rolling behavior of a essentially corresponds to the human foot.

Furthermore, this sole advantageously becomes a special one Non-slip design achieved, thus leading to All-weather use even in snow or on unpaved Serves underground.

Advantageous refinements of the shoe or Outsole arise from the subclaims.

By the formation of the projecting elements in one piece the sole surface is made up of only one part Sole created what processing advantages brings with it. Further measures to connect with the Other components of a shoe are significant only in one reduced scope is necessary, especially one Glue the sole to the other components of the shoe dispensable.

The same applies to the at least one longitudinal rib.

The fact that the one longitudinal rib in the front end region or toe area of the sole surface of the outer contour of the sole surface follows essentially the same distance from this, being in along the inside of the shoe sole this area extends, the good rolling is increased and especially a power transmission of the foot when pushing off of the shoe is advantageously supported for the next step.

By forming a flat projecting element in the heel end area, the cushioning effect in the sole when they hit the ground at the start of the rolling motion the sole of the shoe increases.

The same applies to the band-like projecting element at the front end of the shoe sole.

By forming a second longitudinal rib parallel to the first is advantageously the support function and stabilization the sole of the shoe increases, causing a twist the sole, which is sufficient for the rolling process is elastic, is essentially avoided.

Because in the area between the heel area and the ball of the foot a border area on the inside and on the outside of the sole contour towards the insole is offset and over the substantially flat inner surface the sole surface protrudes that in this area the contact surface of the sole on the floor is reduced, which further improves the rolling process.

The width of an edge region is advantageously approx. 10 to 20% of the total width of the sole in this area.

If the lattice-like protruding elements are formed that they are different, human Have the shape of the sole of the foot adjusted, so it becomes a special one good fit achieved that of anatomical training follows one foot. This will corresponding power and Pressure transfer areas avoided and the effect of a supported barefoot-like walking.

The most protruding ones are located here Elements at the border areas to the outer edge of the sole, whereby the sole has a corresponding lateral guidance Allows foot opposite.

The present invention further relates to a shoe with a tanned leather upper, the one with an insole made of natural material, like leather, Cork, etc. connected and on an outsole made of natural latex is attached, the shaft facing outward Has edge that with the insole on its edge connected is. Also on the outer wall is the outsole a lateral bead is formed, which has an internal fillet limited and the interconnected edges of the shaft and the insole are arranged in the groove, the Shaft and insole by means of a bead and the edge-running outer seam attached to the outsole are. The shoe according to the invention is characterized by this that he has an outsole according to one of claims 1 to 11.

The figures described in the following are the same Parts designated with the same reference numerals.

In Figure 1 is a shoe or outsole according to the invention 1 shown in plan view. Figure 1 shows the inside 3 the shoe sole 1 according to the invention, it being apparent around the left sole of a corresponding pair of soles acts.

The shoe sole 1 has a substantially flat inner surface 5, from the protruding towards the insole Elements 7 protrude. The protruding elements 7 are designed as a rectangular grid.

The shoe sole 1 has a longitudinal axis A, which is in the essentially in the middle of the heel area 9 of the sole 1 extends.

Following the anatomical formation of a human foot is the ball of the foot and toe 11 towards the inside 13 of the shoe sole 1 arranged offset.

The projecting elements 7 are formed from webs that on the one hand, parallel to each other in the direction of the longitudinal axis A run and on the other hand also parallel to each other in a direction to the longitudinal axis A.

The height of the protruding elements 7 above the inner surface of the sole 5 varies, one being essentially the sole area surface contour of a human foot is formed at which the lowest height of the projecting elements 7 are provided in the ball area and the greatest height in the heel area 9.

As can furthermore be seen from FIG Shoe sole 1 in the heel area 9 five parallel extending longitudinal webs 15.

Of course, depending on the size of the shoe sole 1 correspondingly different number of longitudinal webs 15 can be selected, for shoe soles of children's shoes, for example lower number.

To support the footbed of the human foot is on the inside 13 of the shoe sole 1 a crescent Reinforcement area 17 provided the spaces between the projecting elements 7.

The crescent-shaped reinforcement region 17 extends here in the direction of the longitudinal axis A of the shoe sole 1 as from Figure 1 clearly visible.

Furthermore, the shoe sole according to the invention has in itself known manner an edge 19 which extends around the entire Sole inner surface 5 extends. The formation of the margin 19 is written below with reference to Figure 3 will.

The underside 21 of the shoe sole 1 is shown in FIG.

As can be seen from this figure, there are 21 on the underside downwardly projecting elements 23 provided in Form of interrupted lines running transversely to the longitudinal axis Webs 23 are formed.

These transverse webs 23 result in good rolling behavior reached the sole of the shoe, being due to a clear relief of the bottom of the shoe sole a universal The sole can also be used in winter or on flexible surface is possible.

Parallel to the outer contour of the sole or outside 25 and in a certain distance from this are two longitudinal ribs 27 and 29 provided the distance between each longitudinal rib significantly less than half the sole width in the heel area 9 is.

The two longitudinal ribs 27 and 29 extend from the Outer contour 25 along the sole tip 31 to the inside 13, as shown in Figure 2.

In the front end area around the tip 31 of the shoe sole 1 a band-like protruding portion 33 is provided around it and at the rear end of the shoe sole 1 is also a projecting area 35 is provided. The amount of protruding Elements 23, the projecting longitudinal ribs 27th and 29 and the projecting areas 33 and 35 is in essentially the same.

In the intermediate section between the ball area 11 and the heel area 9 is both on the inside 13 and on the outer side 25, an edge region 37 and 38 is provided which protrudes from the underside towards the inside 3 of the sole, so that these two edge areas when running As a rule, do not touch the floor.

In the illustrated starting example of the invention Shoe sole 1 is the width of the edge regions 37 and 38, respectively approx. 10 to 20% of the total width of the sole in this area.

On the underside 21 of the shoe sole 1 can continue Advertising field 39 may be provided, for example, with the Brand of the sole and / or shoe manufacturer is provided.

Figure 3 shows a sectional view along the line III-III of Figure 1.

At the bottom of the shoe sole 1 are the average longitudinal longitudinal ribs 27, 29 and the transverse ones Web 23 can be seen. The projecting inward Crosspieces 7 are arched downwards to match the corresponding To be adapted to the shape of the human foot.

The edge area 19, the projecting elements 7 and the Elements on the underside 23, 27 and 29 are advantageous integrally formed with each other. On the outside wall, Inside 13 and outside 25 of the invention Shoe sole 1 is formed on a lateral bead 41 which an inner groove 43 bounded. The bead 41 turns on closed on the inside by a web-like edge 45, which is essentially perpendicular up and around the whole Sole runs around.

Figure 4 shows a shoe 47 in partial section, the one according to the invention Sole 1 has.

The shoe 47 has a shaft 49 which is on its lower Edge 51 together with an inner lining 53 to the outside bent and with an edge 55 of an insole 54 by a Seam 57 is sewn. The edges are sewn together so that an outer projecting peripheral seam edge 59th arises in the on the inside of the barrel or Shoe sole circumferential groove 43 is arranged. The Groove 43 is delimited by the bead 41, which, like clearly seen in Figure 3, on the outer wall of the Shoe sole 1 is formed laterally in the upper area. Of the Bead 41 is doubled through with an outer seam 61 which the shaft 49 with the insole 54 and with the Outsole 1 are connected.

As can be seen from FIG. 4, the components of the shoe 47 are sewn together exclusively, in particular Avoid sticking the components together are.

In summary: it is with the help of the invention Outsole or shoe sole 1 created a shoe component, with the help of an anatomically correct walking that the Barefoot walking corresponds, practically completely achieved becomes.

Furthermore, as described above, in connection with the other components of a shoe with a new shoe created the sole of the invention, in which the feeling of barefoot walking is realized.
