Abstract

The outsole (1, 3), particularly for sports shoes (2), can be provided with a high degree of elastic deformability in a tangential direction thereby achieving a good cushioning even when the shoe strikes the ground with a slanted and somewhat sliding impact. The invention provides that the outsole (1), beyond at least one critical deformation in the area deformed thus far, is, however, essentially stiff with regard to tangential deformation. This provides the runner with a more sure footing on the respective impact or loading point. The runner can push off once again from the loading point also without losing ground. A floating effect on the sole is thus prevented. The sole can, as a whole or in several parts, also be detachably fastened to a middle sole (4) of the shoe (2).

Description

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is described in more detail according to embodiment.

At first will describe an embodiment,, yet can well describe principle of the present invention according to this embodiment although this embodiment definitely is not preferred according to Fig. 1.

Fig. 1 illustrates and is equipped with according to 1 roller skate 2 at the bottom of the roller skate of the present invention.1 hollow member 3 by a plurality of section shapes constitutes at the bottom of the roller skate, and these hollow members 3 have pipe 3.1, and with the web 3.2 that forms above for example by being adhesively fixed at the downside of the intermediate sole 4 of roller skate 1.Hollow member 3 adopts the material as elastomeric material to make, and the load that this material can take place when skidding is down to the small part strain.The height that this material preferably also has with respect to other materials adheres to friction, but mainly is with respect to self.A plurality of hollow members 3 dispose successively at the longitudinal direction of roller skate 2, wherein, and retention gap in the zone at ball and between following.The overall width that hollow member 3 can pass through roller skate 2 respectively extends.Yet as shown in Figure 2, also can be with two or more this hollow member 3 side direction and row arrangement.

If roller skate 2 is as Fig. 1 b) shown in, and by shown in the load arrow P 1, bear load before for example when contacting to earth, being tilted to, then after the load initial elasticity damping under the vertical and horizontal distortion situation of tubular portion 3.1, when the suitable dimension of this pipe portion is determined, the compression fully of this pipe portion takes place, and therefore occur in this pipe portion upper half shell 3.1.1 and should the lower half shell 3.1. 2 of pipe portion between friction connect (referring to Fig. 3).The further horizontal distortion that this friction connects at pipe 3.1 applies a high resistance like this, makes that this horizontal distortion is possible in the residual elasticity scope of material in fact only, and therefore can ignore.Therefore, skidding person in this position and under this state of 1 at the bottom of the roller skate, have a kind of reality of level no longer movable with the contacting of ground 5, and have good and safe standing with regard to this point.

In addition, as Fig. 1 c) shown in, skidding person at first also can push open once more from the position that is used to carry out next step according to Fig. 2, and need not stand distance loss in this regard, this is because because above-mentioned friction connects, make tubular portion 3.1 in noticeable scope, the direction of the load of being indicated by arrow P 2 that takes place when pushing open in fact can the occurred level distortion.Nature, prerequisite in the case is, contact to earth and push open between keep load that the deformed region at the bottom of the roller skate is applied, yet this situation when being normal skidding.

Fig. 2 illustrates the back view of the sport footwear 2 of Fig. 1, that is: a) do not bear when loading, and b) when load is tiltedly born in inclination.And in this regard, producing between the upper half shell 3.1.1 of tubular portion 3.1 and the lower half shell 3.1.2. under the situation that friction connects, the compression of the tubular portion 3.1 of hollow member 3 can take place, therefore, the wearer of roller skate 2 also side direction obtain contacting of a kind of stable and in fact indeformable and ground 5.

Above-mentioned embodiment is characterised in that extremely long deformation path, these deformation paths according to Fig. 1 a) the state that does not bear load and according to Fig. 1 b) have between the state that friction connects, can reach fully, if possible, even greater than 50% greater than 20%.Use the roller skate of Fig. 1 and Fig. 2, skidding person is just like " speeding across the sky ", and do not have unsafe sense of standing at any time, and in the scope of contacting to earth, always have with ground directly, firm and so be safe contacting to earth.
