Abstract

An outsole ( 1 ) for athletic shoes ( 2 ) having stud-type cleat elements arranged in the front sole area ( 3 ) and heel area ( 4 ), the cleat elements extending in a conically tapered manner from the base ( 6 ) thereof to the contact surface ( 7 ). To improve the outsole, in order to enable improved contact of the feet when they are placed on the ground, even when the ground is moderately hard, the height (h<SUB>red</SUB>) of at least one cleat element ( 5 ') in the sole edge area ( 12 ) of the heel area ( 4 ) is reduced in relation to the average height (h<SUB>norm</SUB>) of the other cleat elements ( 5 '') in that area.

Description

The invention relates to an outsole for sports shoes, especially football boots, with in the front sole area and Heel area molded cams from their base to Tread conical towards tapering.

An outsole of the generic type is known from DE 37 03 932 A1 known. To the sole are by a common injection molding process, through which the sole is made, cams molded, resulting from the Lift base geometry of sole out normally. With such Cam results in a sports shoe, in particular on hard soil has good adhesion properties.

From DE 24 54 241 A, a sports shoe is known in the Heel has a so-called. Gleitschutzprofilierung. For this purpose it is provided that the upward around the heel curved sole of the shoe with anti-slip lugs equipped in proportion to the height of the tunnels in their height are reduced. This ensures that the Shoe in the bottom has improved adhesion when the wearer the shoe wants to perform a spreading step or must.

US 3,988,840 discloses a sole for a sports shoe, characterized by a particularly good traction on the ground should be awarded. It is envisaged that in Sohlenrandbereich - and over the entire circumference of Sole running around - cams are arranged, all in their height are reduced in height relative to those cams, which are located in the "inside" of the sole.

From US 4,327,503 a sports shoe is known, the sole equipped with cams. It is envisaged that both Cams with greater height as well as cams with reduced height be used.

It has proved to be disadvantageous that, especially in medium-hard soil, for example when the soil is frozen; an undesirably hard putting on of the foot on the ground he follows. Furthermore, with such soil, the stability less, as a "stilt effect" occurs: The Foot contact area is at least the height of the cams above the ground.

The invention is therefore based on the object , a sports shoe of the known type such that even with medium-hard soil better sliding of the foot when placed on the floor. Furthermore, the "stilt effect" should be reduced, so that a safer placing of the foot on the floor is possible.

The solution of this object by the invention is characterized in that the height of at least one cam in the sole edge region of the heel region is reduced compared to the average height of the other cams in this region, wherein all cams in this range, in an angular range of 30 ° to 135 °, preferably from 60 ° to 120 ° of an imaginary circle which defines the end region of the heel region, is reduced in height and wherein the reduced-height cams face the ground when the sports shoe is on the ground.

This results in particular an improved initiating the shoe on the floor; furthermore, the "stilt effect" reduced.

Advantageously, the reduced in height thereby Cams maximum 60%, preferably maximum 30% of average height of not reduced in height Cams on. The base of the molded cams can one elongated, in particular one of an ellipse shape similar Have cross-section.

Further developments are given in the dependent claims.

• Beim Aufsetzen des Fußes auf dem Boden erfolgt ein besseres Eingleiten des Fersenbereichs des Schuhs auf dem Boden.
• Der "Stelzeneffekt" wird vermindert, so daß sich eine verbesserte Standsicherheit ergibt.
• Es wird ein besser kontrolliertes Auftreten auf dem Boden möglich.
• Unnatürliche bzw. schädliche Hebel, namentlich beim Aufsetzen des Schuhs auf dem Boden, werden durch die in der Höhe reduzierten Nocken vermieden, so daß der Fuß besser auf dem Boden abrollen kann, ohne daß die Standsicherheit vermindert wird. Damit ist ein natürlicheres Abrollen des Fußes auf dem Boden möglich.
• Es kann ein gleitender Auftritt erfolgen, so daß der Fuß einer geringeren Belastung ausgesetzt ist.

With the proposed embodiment of the outsole of a sports shoe the following advantages - especially when used on medium-hard ground - achieved:

• When placing the foot on the ground, a better sliding of the heel area of the shoe on the ground.
• The "stilt effect" is reduced, resulting in improved stability.
• It will allow a better controlled appearance on the ground.
• Unnatural or harmful levers, especially when putting the shoe on the ground, are avoided by the reduced in height cam, so that the foot can roll better on the ground, without the stability is reduced. This allows a more natural rolling of the foot on the floor.
• It can be made a sliding appearance, so that the foot is exposed to a lower load.

represents the top view of the outsole (from below).

In Fig. 1, a left athletic shoe 2 in the side view to see. He has an outsole 1, at the bottom of a Variety of cams 5, 5 ', 5 ", 5"' are arranged. The Cams 5 to 5 "'are in a common injection molding process during injection molding of the outsole 1 injection-molded, ie to the Outsole 1 molded.

The cams 5, 5 ', 5 ", 5"' or a part thereof are both in the front sole area 3 as well as in the heel area 4 of the Outsole 1 arranged. They have a base 6, of which They taper conically to the cam surface 7 run.

In cross-section, the cams 5, 5 ', 5 ", 5"', as well as the cam base 6, an elongated, preferably an elliptical or approximately elliptical shape, as seen in Fig. 3 can be. In the front sole area 3 are cams 5 along of the sole edge region 12, the longitudinal axis 9 in Direction of the sole edge portion 12 run. In contrast, are in the heel region 4, the cam 5 in the sole edge region 12th arranged so that the cam longitudinal axis 9 at least approximately transverse to the direction of the sole edge region 12 runs.

The outsole 1, which has a total sole width 11, is in the front sole area 3 also with inner cam 5 '' ' Mistake. These are of the cam 5 in the sole edge region 12th surrounded and arranged in the embodiment so that their Longitudinal axis 9 in the direction of the sole longitudinal axis 10 extends.

2, according to the invention some cams 5 'have a reduced height h _red in the sole edge region 12 of the heel region 4 in comparison to the average height h _{norm of} the other cams 5 " reduced in height.

If one defines for the end area of the heel area 4 one limiting circle 8 (see Fig. 3), it can be said that within an angular range α, preferably between 60 ° and 120 °, all cams 5 'are reduced in height.

The reduction of the height of the cam 5 'is so made that they have only a maximum of 30% of the height, the the remaining cams average 5 "with normal height exhibit.

The height of the cams 5 in the sole edge region 12 of the front sole area 3 is smaller than the height of not in their height reduced cam 5 "in the bottom edge region 12 of the Heel area 4.

The inner cam 5 "'in the front sole area 3 have a Cam height up, which is less than the height of not in their height reduced cam 5 in the bottom edge region 12th

With the proposed embodiment it is achieved that the Appearance characteristics of a sports shoe, in particular one Football boot, especially on medium-hard ground improved become.
