Description

The invention relates to a continuous, heel-free sports shoe sole made of rubber or plastic with a lower surface part on the running side, on the bottom of which anti-slip agents are arranged are.

Despite the endeavor to make the soil quality of sports fields as even as possible, find in the most stressed areas, e.g. B. in front of the gates of a soccer field planted with grass, Played areas that no longer have a lawn and are softened by the action of rain and can even be muddy. It is therefore necessary to adapt the sports shoes to the different ground conditions adapt.

For soccer shoes z. B. low cleats used on hard places and high cleats used on soft places, while the studs should be particularly rough for smooth places. So far there are no cleats became known that the different requirements on the different surfaces of the Playing fields meet. In addition, when training the bottom of the soles of sports shoes It must also be taken into account that the studs, despite good anti-skid protection, nevertheless prevent the Allow foot on the square in order to prevent leg injuries to the shoe wearer as far as possible.

There are already sports shoe soles with studs, ribs or the like. Known that are made in one piece Rubber or rubber are made and in which the cleats, ribs or the like. In one opposite the Edge deeper surface area are arranged. However, such training is not suitable to adapt the sports shoe sole to the different ground conditions on a sports field. you will be also only used to provide adequate anti-slip protection when walking on soft ground and when Walking on solid ground, e.g. B. od on roads. Like. To achieve sufficient adhesion without the cleats or the like have a disturbing effect.

The object of the invention is to provide the sports shoe sole to be trained so that they can even with very different ground conditions of the playing field provides the necessary anti-slip protection, which is not the case with sports shoes with the well-known cleated soles.

The sports shoe sole is designed according to the invention in such a way that the anti-skid means from one Plenty of well-known tunnels distributed over the deeper base area, which in their Height above the edge strip, whereby the height of the individual studs from the sole tip and from the heel end to the joint located approximately in the middle of the shoe and from the sole edge in the direction decreases towards the middle longitudinal axis of the sole.

edge in a manner known per se with the sole in one piece made of rubber or similar material ζ. B. plastic or prepared leather.

Sports shoes according to the invention offer adequate anti-slip protection on hard places because the Sole is supported on studs that are relatively low compared to the edge. By the unequal There are no difficulties in turning the foot around the vertical axis at the height of the studs.

On soft or muddy places, the tunnels press into the ground, whereby for the Grip the height of the studs above their own base area within the edge is decisive. A Too far sinking is avoided by the fact that after sinking the tunnel into the soft ground Finally, the edge of the sole also bears.

Turning the sports shoe on soft ground is not hindered in this case either because the rear studs are lower and thus when turning around a roughly through the ball of the toe where the studs are are higher, placed vertical axis offer less resistance.

Since the transition of the sole edge and the cleats into the base area according to a further feature the invention takes place gradually, the earth that would otherwise fall between the tunnels and between the The cleats and the edge can easily get stuck again.

The invention is explained below using an exemplary embodiment in the drawing. It shows

Claims (5)

Fig. 2 is a bottom view of this sole, Fig. 3 is a cross section along line III-III of FIG. B. plastic, provided with a central recessed surface part 2 which is bordered by a circumferential protruding edge 3 which gradually merges into the recessed surface part 2. On the base 4 of this part 2 studs designed as a truncated cone with a spherical cap are arranged, the conical part of which is converted into the base with a groove at the foot. From the tip 5 and from the edge 3 of the sole, the height of these studs decreases, so that the foremost stud 6 and the edge studs 7, 8, 9, 10, 11, 12, 13 and 14, measured in absolute terms, protrude higher above the base area than the lugs 15 and 16 in the middle and as the lug 17, which is located further back under the longitudinal arch of the foot. So that the middle studs 6, 15 and 16 get a firm hold on the relatively thin sole part 2, this part is reinforced in this area by a material strip 18. When playing with a sports shoe provided with such a sole on a hard court, the height of the studs above the edge corresponds approximately to that of the low studs that are usually used on hard courts. Due to the gradually decreasing height of the studs towards the middle of the shoe, they do not cause much resistance when the foot is turned around a vertical axis placed through the ball of the toes, even if they are made of rough material, so that knee dislocations or the like when worn such shoes are less common. The difference in height between the tunnels only needs to be very small, e.g. B. a total difference of 4 mm or less between the highest and the lowest stud is sufficient. When playing on soft and muddy places, depending on whether the ground is more or less soft, more studs sink into the ground, whereby the sinking in is countered by a progressively higher resistance, until finally the flat edge and the low-lying base also rest . The studs of the sole according to the invention correspond in this way to the high studs customary in soft places. It goes without saying that the number of studs can be varied depending on the demands that are made on each individual sport. Such a lower part 20 is also provided in the heel part 19 of the sole, in which studs 21 are arranged, the height of which decreases towards the center of the foot. It is obvious that it is of great advantage if the sole with the studs is made from a single piece, because then the gradual transitions can best be realized. However, it is possible to attach the studs to the base area later in a known manner. The sole and the sole edge can also be produced as separate pieces, optionally from different materials. Furthermore, a front or rear piece made of leather can be provided in order to increase the abrasion resistance of the sole in the toe and heel area. Patent application c ι ι κ: 1.
