Definitions

• the present invention relates to shoe soles intended to improve movement on leaky floors such as sand and to eliminate the suction effect on all types of soil.
• the present invention overcomes this problem.
• the soles according to the invention in fact make it possible to remedy the difficulties of movement (instability and effort) on leaky soils such as sand as well as the suction effect on all types of soil.
• the soles have a structure which allows, on the one hand to trap and compress a portion of the leaking material (such as sand) on which a person moves by the simple physical effect of walking, and, on the other hand hand, to remove the suction effect on all types of soil.
• the proposed soles have a structure that presents firm support points on loose soil.
• the present invention therefore relates to a sole for walking comprising a face intended to be in contact with the ground, called the lower part and an opposite face called the upper part, mainly characterized in that it comprises in the lower part of the recesses closed by the upper part making it possible to trap a portion of material on which a person moves, each recess being provided with at least one decompression channel providing a free junction between the inside the recesses and the outside perimeter of the sole.
• the decompression channels can be arranged around the recesses in the lower part of the sole so as to be in contact with the ground.
• the decompression channels can be arranged around the recesses - at any height from the wall of these recesses. According to another characteristic, the decompression channels have a height substantially equal to that of the recesses.
• the recesses provided with decompression channels are at least two in number.
• the depth of the recesses can be identical.
• the depth of the recesses may be different.
• the walls of the recesses make an angle less than or equal to 90 degrees relative to the face of the sole intended to be in contact with the ground.
• the external perimeter of the sole makes an angle less than or equal to 90 degrees relative to the face intended to be in contact with the ground of the sole.
• the sole may consist of a single or several layers of material superimposed, the recesses and the decompression channels being formed on at least the lower layer intended to be in contact with the ground.
• FIG. 1 represents the view in bottom plan of a sole according to the invention
• FIG. 3 represents a variant view in perspective of the sole according to the invention
• FIG. 4 represents a cross section AA in the longitudinal direction of a sole according to the invention
• Figures 5 and 6 show alternative positioning of the channels seen in partial cross-sections.
• a sole is defined, - whether this sole is made up of one or more layers of material superimposed or not, as in all cases, a face 1 intended to be in contact with the ground, called the lower part and an opposite face 2 called the upper part.
• the sole has in its lower part 1 recesses 3 provided with decompression channels 7.
• the decompression channels 7 provide a junction between the interior of the recesses 3 and the outer perimeter 8 of the sole.
• the decompression channels 7 are of geometric or arbitrary shapes and dimensions.
• the decompression channels 7 are positioned on the lower part of the sole or at any height from the wall of the recesses 3 (FIG. 5). According to an alternative embodiment, the decompression channels have a height equal to or substantially equal to the total height of the recesses 3 (FIG. 6).
• the recesses 3 provided with decompression channels 7 are of geometric or arbitrary shapes and dimensions; the bottom of these recesses is closed by the upper part 2. Their walls make an angle less than or equal to an angle of ninety degrees relative to the face 1 intended to be in contact with the ground (base of the sole).
• the thickness of the material 4 corresponds to the depth of the recesses 3; this thickness of material 4 consists of a single layer or of several homogeneous or heterogeneous layers for decorative purposes, of solidity or rigidity, a thickness of material 5 or more coming in a hat over the thickness 4.
• the basic element 6 in which the recesses 3 are made without completely passing through it is either a thickness of material consisting of a single layer of the same composition or consisting of several layers homogeneous or heterogeneous to decorative, solidity or rigidity, a hollow element provided with a resistant envelope.
• the outer perimeter 8 of the sole has an angle equal to, less than or greater than ninety degrees.
• the profile of the upper part 2 can be ergonomic or flat.
• the profile of the lower part 1 can be ergonomic or flat.
• the recesses provided with decompression channels occupy a large area on the total surface of the sole as can be seen in the diagrams.
• These recesses provided with decompression channels are made in a first thickness of material of the same composition or made up of homogeneous or heterogeneous layers by completely passing through it, one or more thicknesses coming in the cap of this first thickness
• the sole may not be solid but hollow.
• the recesses provided with decompression channels are in this case produced in a hollow element provided with a resistant envelope.
• the sole is then in the form of a resistant envelope consisting of a face intended to be in contact with the ground, a perimeter defining the outer edge of the sole and a face opposite to the face intended to be in contact with the ground.
• the face intended to be in contact with the ground has internal walls defining the shape of the obviously and decompression channels.
• the recesses and decompression channels are produced according to known techniques which are best suited to the material constituting the soles: manually or mechanically by cutting, coring, trimming, milling, stamping, extrusion, molding or any other non-limiting technical means making it possible to obtain an obviously and channels.
