Definitions

  • the present invention relates to a sole, in particular an outer sole for a shoe intended for sports requiring a rolling of the foot and / or sliding sports. It relates to also a method of manufacturing soles and a shoe provided with such a sole, respectively a shoe provided with a sole obtained by said manufacturing process.
  • the present invention relates to sports requiring a course hiking, such as hiking, cross-country skiing, skating or classic skiing, downhill skiing, skiing telemark or snowshoeing. It also applies to board sports, such as ice skating, roller skating with wheels in line or not, snowboarding or skateboarding.
  • the sole of sports shoes is formed in one piece.
  • the thickness of the sole is varied.
  • the present invention aims to provide an improved sole to reconcile the contradictory requirements set out above and in particular an improved transmission of efforts and satisfactory flexibility of the sole while keeping production costs modest.
  • a shoe sole sports comprising a front part and a rear part adjacent to the front part, the rear part covering at least the base of the heel area, characterized in that the rear part is rigid and substantially non-flexible, and has a modulus of elasticity between 260 MPa and 200 GPa, and that the rear part extends substantially to the so-called metatarsophalangeal flexion zone.
  • One of the ideas of the present invention is to provide a sole, in particular for a sports shoe, in two parts, a front part and a rear part adjacent to the front part.
  • the rear part is rigid and substantially non-flexible. This characteristic allows an efficient transmission of the forces coming from the user's leg and intended for the direction and / or propulsion of the body of the user, in particular by allowing a grip effective edge or to cooperate with a guidance system of the guide edge type in ski background.
  • the rigid rear part preferably extends in the zone between the heel and the zone metatarsophalangeal.
  • the two parts constituting the sole are overlap in and / or behind the metatarsophalangeal area in a junction area of length adjustable according to the size.
  • the variation of the overlap length allows the manufacture of soles of different sizes on the basis of rear and front parts respectively identical, which considerably reduces production and storage costs by reducing the number of different parts to be manufactured.
  • Figure 1 is shown, schematically, an outer sole 1 intended for a shoe for cross-country skiing.
  • the present invention also applies to all sports requiring transmission of forces from the user's leg and intended to the direction and / or propulsion of the user's body, in particular by an operation generally called edge grip.
  • Examples of such sports disciplines are snowshoeing, cross-country skiing cross-country skiing, telemark skiing, hiking, snowboarding, ice skating or roller skating.
  • the following description will be made with reference to an outer sole intended for a shoe for cross-country skiing.
  • the sole 1 shown consists only of two parts 2, 3, which are adjacent one to the other.
  • the construction of the sole 1 in two parts 2, 3 has the advantage that each part 2, 3, can be optimally designed according to the requirements respectively to be met and so that we can standardize production as we will see below. Freedom of design adapted to the particular requirements of each part 2, 3, independently of the other, is manifest for example by the possibility of a choice of different materials for part 2 before and part 3 back.
  • the rear part 3 extends in an area between the heel 4 and the area 5 of natural flexion called metatarsophalangeal.
  • the front part 2 of the sole 1 can be provided with a coupling element 6, such as a transverse axis, intended for coupling to a sliding support such as a cross-country ski not shown in the figure.
  • This sliding support can be for example a ski whatever, an ice or roller skate, a snowboard or a snowshoe.
  • the rear part 3 is rigid and substantially non-flexible, which prevents losses by damping and parasitic deformations and allows better transmission of forces.
  • the part rear 3 is made of any material guaranteeing almost flexibility of this part, and in particular in plastic of appropriate rigidity possibly reinforced by fibers such than glass or carbon, or metallic materials.
  • This rear part said to be rigid and substantially non-flexible, will have a elastic modulus between 260 MPa (Mega Pascal) and 200 GPa (Giga Pascal).
  • the front part 2 is preferably flexible, so as to allow an unwinding as natural as possible at the foot. This characteristic brings advantages with respect to use for sports such as cross-country skiing and hiking which require the area to run metatarsophalangeal of the foot.
  • This front part 2 will therefore preferably be made of plastic material having a flexibility appropriate for such an unwinding of the foot.
  • FIGS. 2a, 2b and 4 illustrate another embodiment of the present invention, and in particularly the method of manufacturing a sole according to the present invention.
  • the front part 2 and the rear part 3 of the sole 1 are overlap on a junction zone 5 of predetermined length "L", this length being adjustable in function of the shoe size as will be explained later.
  • the junction or overlap area preferably extends into and / or behind the metatarsophalangeal flexion zone.
  • the extreme front limit of the overlapping zone 5 is formed by the axis " ⁇ " of articulation metatarsophalangeal.
  • the overlapping zone 5 will preferably have a rigidity between those of the rear part 3 and the front part 2, or even a rigidity ranging gradually decreasing from its junction zone with the rear part, to its zone of junction with the front part for a perfect transition between these two extreme rigidities.
  • front parts 2 and several rear parts 3 which are respectively identical and have shapes corresponding substantially to the front part, respectively back of a human foot.
  • front 2 and / or rear 3 parts could also have a shape which requires a cutout for the finishing of the sole, namely a essentially rectangular shape.
  • the front parts 2 and the rear parts 3 can be formed from different materials. A choice of different materials also makes it easier to predict different stiffnesses, if desired, of the front pieces 2 compared to rear pieces 3.
  • the front part 2 is aligned with respect to the rear part 3 in a way overlapping.
  • the two parts 2, 3 can be aligned so that their axes longitudinal medians respectively M-M 'form an angle corresponding to an angle of the anatomy natural of the foot instead of being confused.
  • the length respectively "L1, L2" is determined. (cf. Figures 2a, 2b) overlapping of the two parts 2, 3, so that the length respectively "P1, P2" (see Figures 2a, 2b) effective of the finished sole corresponds to the size desired of the sole, and therefore of the shoe which will be provided with such a sole. He is at note that the difference between two consecutive sizes is generally around 7mm. So, as the comparison of FIGS. 2a and 2b clearly illustrates, an overlap over a length "L1" more large makes it possible to obtain a sole with a shorter overall length "P1" and vice versa.
  • a combination of certain identical front parts 2 and rear parts 3 identical is used for the manufacture of soles 1 whose length "P" corresponds to a range two to three sizes. This results in a reduction of half respectively by a third of the stock of parts 2, 3, different.
  • the variation of the overlapping length "L” is therefore equal to 14 and 21mm respectively.
  • the front part 2 which overlaps the rear part 3.
  • This arrangement presents particularly advantages concerning the durability of the fixing of the front part 2 to the part rear 3, in particular when the front part 2 has a rigidity less than that of the part rear 3.
  • the front end 31 of the rear part 3 has in the longitudinal direction a decreasing bevel section, as well as the rear part 21 of the front part 2. This allows on the one hand, an overlap of the two parts without excess thickness in the transmission area, and secondly, to modulate the rigidity of the transmission area in the longitudinal direction.
  • the front part 2 is fixed relative to the rear part 3 in a way solidarity.
  • the preferred means of attachment are bonding and riveting.
  • the rear part 3 of the sole 1 forms a monobloc assembly with a rear buttress 8 of the shoe.
  • Said buttress 8 surrounds the heel of the foot like a shell.
  • the buttress 8 extends from the heel area 4 to the natural metatarsophalangeal flexion zone 5.
  • the holding effect, like a shell, of the heel of the foot by the monobloc assembly formed by the rear part 3 of the sole 1 and the buttress 8 is significantly improved when the buttress 8 is substantially rigid, and of a rigidity similar to that of the sole.
  • the rigidity of the buttress 8 is still less than the rigidity of the rear part 3 of the sole 1, which, as mentioned above, is substantially non-flexible.
  • the choice of stiffnesses of the buttress 8 and of the rear part 3 of the sole 1, respectively, can be carried out optimally by forming the buttress 8 and the rear part 3 of the sole 1 in the same material or on the contrary in different materials, while keeping the whole piece.
  • the preferred materials for the buttress 8 are leather or plastic materials possibly reinforced with inserts made of metallic materials or glass or carbon fibers.
  • Figure 4 is a bottom view showing a sole according to the present invention. As represented in the figure and in order to better correspond to the natural shape of a human foot, the two parts 2, 3, are aligned so that their median longitudinal axes M-M 'form a angle instead of being confused.
  • the front part 2 of the sole 1 has two zones 11, 12, which are preferably formed from different materials.
  • Zone 11 is the overlapping area "L" of the front part 2 of the sole 1, as indicated previously this overlap zone 11 can extend forward up to the axis " ⁇ " of metatarsophalangeal joint.
  • this overlap zone 11 has a rigidity greater than that of the front zone 12 and which is between the rigidity of the front part 2 and the rigidity of the rear part 3 of the sole 1.
  • the heel zone 4 of the rear part 3 of the sole 1 is, in particular in the case of a Cross-country ski boot, provided with a guide groove 10 which is able to cooperate with a device in the form of an edge provided on a sliding support, for example a cross-country ski.
  • a groove of guide also extends into the front part 2 of the sole.
  • the rear part 3 of the sole 1 can, depending on its desired use, be provided with any cooperating system with a sliding support and / or a profile for improved hold and edge grip sole 1 on the ground.
  • the front part 2 of the sole 1 is, as already described, provided with a hooking element 6 for an articulated binding of the front of the boot provided with the sole 1 on a cross-country ski.
  • the front part 2 can also be provided with any other fixing system cooperating with a sliding or walking support, such as a snowboard or a snowshoe.
  • a sole according to this invention may as well have more than two constituent parts, for example by dividing the rear part and / or the front part in several sub-parts.
