Sole provided with overturning anti-slipping means

A shoe sole comprising:

• rigid or semi-rigid support elements;
• slots defined in the sole;
• an anti-slipping device in which anti-slipping or anti-sliding devices are provided, the anti-slipping or anti-sliding devices not being directly secured to the shoe sole, the anti-slipping or anti-sliding devices being but arc secured on the rigid or semi-rigid support elements configured to be overturned to be hidden in the slots, overturning of the support elements of the anti-sliding devices occurring about horizontal axes such that the support elements are parallel to a resting plane of the sole, by snap-fitted pins within respective rotation seats including cubic blocks each laterally provided with a corresponding hinging hole, each of the cubic blocks being secured to the sole by one of the snap-fitted pins;
• and
• at least one mushroom-shaped coupling element formed as one piece with a respective cubic block, the coupling element being configured to anchor a respective one of the cubic blocks forming the respective rotation seat of the overturning support element to the sole, the coupling element being removably snap-fitted in a corresponding accommodation seat arranged by molding in the sole next to the respective slot where the overturning support element is accommodated after the overturning, without interfering with the integrity of the sole itself, thus avoiding a simple torsion of a bottom of the sole from causing detachment and loss thereof,
• the cubic blocks forming the respective rotation seat of the overturning support element and the mushroom-shaped coupling element configured to position the overturning support element in place on the sole are made of a material having the same elastic modulus as the overturning support elements, but less elastic modulus than the elastic modulus of a material of the sole,
• the overturning support elements and the cubic blocks forming the rotation seats are configured to be replaced by maneuvers by a user without requiring particular tools due to elasticity of the couplings,
• wherein both the snap-fitted pin of the respective overturning support element of the anti-slipping or anti-sliding devices and the related seat in the cubic block acting as a pivot for rotation thereof, have oval geometry which forces switching from an extracted position of the slipping or anti-sliding devices to a retracted position thereof, or vice versa, without stable intermediate positions, thus ensuring that the support elements are securely located in one or another of an operating position and a rest position.
