Problems solved by technology

[0014] In this case, one problem is to measure or determine the data that is actually relevant to the influence of pronation, by which the influence on pronation can be effectively exerted
These data cannot be divorced in a simple way from the parameters that generally determine running dynamics

Embodiment Construction

[0039] exist figure 1 The lower region of the leg of a runner wearing shoe 1 can be seen in . During a stride or a stride cycle, the shoe 1 is in the air for a certain amount of time. It then landed 5 and rolled over on the ground before it lifted up again. The shoe 1 has a sole 7 with a tread 8 . The accompanying drawings represent the situation shortly before the shoe 1 hits the ground 5, where the shoe 1 is still in flight.

[0040] The shoe 1 is equipped with a system 2 , 3 , 4 , 10 for influencing the pronation of the foot of the wearer of the shoe 1 . The system includes at least one sensor capable of detecting a parameter significant to pronation. Currently, the rotational speed dφ / dt of the shoe is used as an important parameter as a derivative of the angle φ. The angular velocity dφ / dt is measured about an axis 9 inclined at an angle both to the longitudinal axis L of the shoe 1 and to the horizontal. It has proven expedient to use as sensor 2 a gyroscope (gyros...

Abstract

The invention relates to a method for influencing the pronation behaviour of a shoe (1), in particular a sports shoe, wherein a) at least one parameter (F, dF / dt) that is relevant to the pronation behaviour is measured (2), b) the measured parameter (F, dF / dt) is fed to a control unit (3), c) the control unit (3) emits a control signal that influences the pronation behaviour to a control element (4) and d) the control element (4) modifies a property of the shoe (1) relevant to the pronation behaviour. According to the invention, in order to improve the influence on the pronation behaviour, the processing of values of a parameter (Phi, dPhi / dt) measured according to step a) takes place from a reference time point (tK) onwards, said time point being determined when the shoe (1) is placed on the ground.

Description

technical field [0001] The invention relates to a method for influencing the pronation properties of a shoe, in particular a sports shoe, wherein [0002] a) measurement of at least one parameter important to the properties of pronation, [0003] b) feeding the measured parameters to a control unit, [0004] c) the control unit sends an adjustment signal affecting the pronation properties to an adjustment element, and [0005] d) The adjustment element modifies a characteristic of the shoe which is relevant for the pronation properties. Background technique [0006] Systems integrated into shoes, in particular sports shoes, are known in the prior art, with which a property of the shoe can be actively influenced in order to influence the pronation. These systems operate in a method of the type described. For example, the spring or braking properties of a shoe can be affected. For this purpose, certain states of motion of the shoe are measured and the spring or braking pr...
