Definitions
- the invention relates to a shoe sole.
- the shoes are all provided with a sole coming into contact with the ground.
- This sole can be monolayer or be more complex.
- the layer in contact with the ground is a wear layer which can be smooth or notched or have studs or protuberances for its grip with the ground, this notching or these studs are of the same material as the rest of the wear layer and there are no boundaries between these studs and the rest of the layer.
- the material is resistant to abrasion and relatively little compressible.
- the protrusions are therefore of the same material as the rest of the outsole and come from the same injection or molding cycle as the rest of the wear layer.
- the sole then has one or more layers forming the more technical body of the sole.
- This technical body can be simple or multilayer of more or less flexible material depending on the use of the shoe equipped with the sole.
- a city shoe has a completely different sole from a hiking or running shoe.
- the layers are multiple with more or less dense materials distributed over the entire sole.
- a difference is usually made between the forefoot and the heel.
- the heel does not undergo the same stresses as the front part of the foot depending on whether one is walking or running.
- the multiplication of layers therefore makes it possible to separate and adapt the behavior of the front part of the sole from that of the rear.
- Balls are known, for example, housed in individual cavities EP-A-299.669 or in a cavity grouping together several balls EP-A-383-685 so that they roll.
- These balls have massaging and / or shock absorption effects. These balls are not in direct contact with the ground. They serve as absorbent interfaces between the outsole and the upper layers.
- Shock absorption is the function sought on these shoes, in particular sports shoes.
- the purpose of these inserts is therefore to absorb energy and restore it to the sole.
- the wear layer transmits the forces to the upper layers which must then absorb the forces.
- a heel US-A-1 012 597 is known in leather in which free-spinning balls are implanted in housings. These balls are slightly protruding and are made of rubber.
- a sole FR-A-601278 which comprises a lower wear layer having holes through which are engaged cylindrical studs presented by a rubber plate forming an intermediate layer between the perforated lower layer and an upper layer.
- the invention proposes a new sole which brings better dynamism to the wearer of the shoe equipped with said sole.
- the invention relates to a sole comprising protuberances on its face in contact with the ground, this sole being characterized in that at least some of these protuberances are in the form of spheres and are embedded in mid diameter in the thickness of said sole.
- FIG 1 a vertical section of a shoe sole
- FIG 2 A vertical section of a sole variant.
- a shoe sole 1 is seen. It has a face 2 in contact with the ground.
- these protrusions 3 are in the form of spheres 3 and are partially embedded in the thickness of said sole.
- Each protuberance will be embedded at mid-diameter.
- these protrusions 3 are distorted from the layer of the sole which receives them and are partially housed in cavities 4 where they are fixed in particular during the injection or bi-injection or overmolding process or even by an adhesive.
- cavities 4 are open downwards and are in a hemisphere. There exists a kind of border between the protuberances 3 and the body 4 of the sole so that the forces generated by the contact of the protuberance with the ground will propagate in the sole in the directions of a half sphere due to the spherical shape of the protuberance and the fact that it is embedded at mid-diameter in the sole.
- the balls are harder than the layer containing them
- the protrusions can be, for example, latex, rubber, thermo-plastic rubber known under the designations “TR” or “TPR” .11 can be a so-called light variant of these materials.
- thermo-polyurethane TPU
- polyurethane or even
- EVA ethyl vinyl acetate
- a crushing of 3 mm is obtained with a load of 22.2 N.
- Another advantage of this type of sole is that it is possible to adapt the distribution, the dimensions and / or the natures of the spheres according to the points of impact of the sole with the ground.
- part of the spheres will have a first diameter and between these balls will be provided other balls of smaller diameter.
- a bi-injection or multi-injection process can be used to form and fix these spherical protrusions in the thickness of the sole.
- Figure 2 shows a variant sole comprising a forefoot pad and a heel.
- the shoe is not necessarily provided on its heel or on its forefoot pad with spheres.
- the spheres are carried by a tip 5 relating in particular by interlocking on the body of the heel.
