Definitions
- the present invention relates to a "grind" shoe, that is to say intended for producing figures by sliding on various elongated supports such as stair railings, rails, edges of walls or low walls, etc.
- FIG. 1 There is also a shoe on the market represented in FIG. 1 and the sole 1 of which comprises, at the level of the arch of the foot, a sliding and wear plate 2 fixed to the sole by means of screws 3 cooperating with an insert (not shown in the figure) arranged between the sole and the upper.
- the sliding and wear plate of this known shoe has a rectangular shape and very "flat".
- Such a shape of the sliding plate in practice allows the realization of only one type of figure, namely that called “Royal” which consists of sliding on a bar or the like, the two feet parallel and arranged transversely to the direction sliding on the said bar.
- the flat shape of the sliding and wear plate does not allow a "lock” effect, that is to say of jamming / wedging on the sliding support.
- Such a construction therefore only allows sliding and provides no means of guidance and braking. Furthermore, the insert on which the sliding and wear plate is fixed is disposed directly between the upper of the shoe and the sole and can therefore be a source of discomfort, especially when walking.
- the sliding and wear plate can be torn off relatively easily due to the sole fixing by the screws 3, which are themselves subject to wear.
- the purpose of the present invention is to remedy these drawbacks and to provide a shoe called "grind", improved which allows in particular to achieve a greater number of figures.
- This object is achieved in the shoe according to the invention which is of the type comprising a sole provided on its underside with a transverse wear reinforcement disposed in the central zone of said sole, by the fact that said transverse reinforcement has the shape of a cylinder portion, arranged transversely to the longitudinal axis of the sole, and having a concave curvature oriented downwards. 2
- the arch-shaped configuration of the sliding and wear reinforcement in the central area of the sole allows better wedging of the shoe on the sliding surface and in particular allows for "edge grip” effects similar to that we meet in alpine skiing, allowing to slow down and therefore to control the slide.
- the shoe comprises a longitudinal reinforcement, disposed on either side of the transverse reinforcement and defining a longitudinal groove on either side of said transverse reinforcement.
- the "cross" shape of the reinforcement thus obtained allows other figures to be produced, opening up the possibility of sliding along the longitudinal axis of the foot.
- FIG. 1 is a perspective figure, seen from below, of a shoe according to the prior art
- FIG. 2 is a figure similar to FIG. 1 of a shoe according to a first embodiment of the invention
- FIG. 3 is a figure similar to FIG. 2 according to a second embodiment
- FIG. 4 is a sectional view along IV-IV of FIG. 2,
- FIG. 5 is a sectional view along V-V of FIG. 2,
- FIG. 6 is a sectional view along VI-VI of FIG. 2,
- FIG. 7 is a sectional view of the insert of FIG. 6 according to another embodiment
- FIG. 8 is a view similar to FIG. 7 according to another embodiment
- FIG. 9 is a perspective view showing the underside of a shoe according to another preferred embodiment.
- FIG. 10 is a partial sectional view along X-X of FIG. 9,
- FIG. 11 is a partial sectional view along XI-XI of FIG. 9,
- FIG. 12 is a partial sectional view along XLT-XII of FIG. 9,
- FIG. 13 is a partial sectional view along XLIII-XIII of FIG. 9,
- FIG. 14 is a partial sectional view along XIV-XTV of FIG. 9,

- FIG. 16 is a partial sectional view along XVI-XVI of FIG. 9,
- FIG. 17 is a partial sectional view along line XVII-XVII of Figure 9.
- the shoe "grind” 10 consists of a sole 20 surmounted by a rod 11 (shown in phantom in the figure).
- the sole 20 has on its lower face two sliding and wear reinforcements, respectively transverse 30 and longitudinal 40.
- the transverse reinforcement 30 is arranged transversely in the central zone 21 of the sole. It has the shape of a portion of cylinder of revolution having a concavity oriented downwards.
- This cylinder portion has a substantially constant radius of curvature and in this case between 30 and 40 mm (cf. FIG. 4).
- a radius of curvature presents a compromise with respect to most of the gliding surfaces used and therefore allows better guidance and attachment and therefore improved braking possibilities on said surface. Therefore a larger number of figures can already be achieved thanks to this simple construction compared to the prior art.
- other values of radius of curvature can also be chosen.
- the transverse reinforcement 30 is extended on each side of the sole by a lateral rise 32 which has, in the transverse direction of the shoe, a convex curvature and which in the longitudinal direction goes widening from the bottom 31 of the portion of the cylinder towards the outside of the sole.
- This lateral ascent 32 also makes it possible to improve the guiding and the attachment of the sole on the sliding surface, in particular in "edge grip", that is to say sole inclined with respect to said surface since the surface of contact is then increased.
- the curvature of the ascent 32 not only is opposite to the curvature of the central zone 30, but is also oriented longitudinally in a direction perpendicular to that of the said central zone 30.
- the radius of curvature of the lift 32 is between 40mm and 60mm.
- curvature of the ascent 32 can also go up to the rod 11 in order to protect it during slips and figures.
- the longitudinal reinforcement 40 defines two aligned grooves 41, 42, arranged on either side of the transverse reinforcement 30, along the longitudinal axis 23 of the sole.
- Each groove 41, 42 is in fact defined by a portion of cylinder of revolution, the concavity of which is turned downwards and having the same radius of curvature, preferably between 20 and 30 mm.
- the bottoms of the two grooves 41 and 42 are aligned and are arranged less deeply than the bottom 31 of the groove of the transverse reinforcement 30 relative to the bottom surface of the sole, or, in d In other words, the grooves 41, 42 are less dug than the transverse groove 30. 4
- the bottoms of the grooves 41, 42 could also be aligned with the bottom 31 of the groove 30, the main thing being that the groove 30 does not form a projection relative to these grooves 41, 42.
- the sole 20 defines in its lower face a longitudinal groove extending over the entire length of said sole and interrupted only in its middle by the transverse groove 30. This results in a possibility of guiding over the entire length of the sole in longitudinal direction.
- each of the grooves 41, 42 is interrupted by a transverse slot respectively 43, 44.
- the transverse slot 43 is wide and arranged substantially in the metatarsophalangeal articulation zone, while the thinner transverse slot 44 is disposed in the heel area.
- slots 43, 44 are provided both at the front and at the rear of the shoe.
- the number, the shape and the arrangement of the slots 43, 44 is variable and depends on the desired effect.
- a slit is especially necessary in the metatarsophalangeal articulation zone so as not to hinder the course of the foot.
- the insert 30, 40 is preferably made in one piece, in one piece. According to a preferred embodiment, it is glued in the sole, between an intermediate sole 25 and a wear sole 26, and for this purpose has hooked zones 50 arranged laterally over the entire length of the insert parts 41, 42, as shown in Figure 6. It can also be molded.
- the midsole is made of a cushioning material known per se such as foam material (polyurethane foam, neoprene, polymer) EVA (ethyl vinyl acetate), neoprene, etc.
- foam material polyurethane foam, neoprene, polymer
- EVA ethyl vinyl acetate
- Such a construction allows shock absorption and is therefore particularly advantageous for a "grind” use involving shocks against different supports.
- the layer 25 will be more or less thick. The material may also be different if we are simply looking for a filtration effect.
- the midsole 25 can extend over the entire surface of the sole or simply at the level of the insert 30, 40 for localized shock absorption.
- each reinforcement portion 30, 41, 42 is provided with a flap respectively 35, 45, so as to form a wear-resistant transition between said reinforcement and the outsole on the stem. 5
- Figures 7 and 8 illustrate other embodiments of the longitudinal grooves.
- the groove 140 has a substantially rectangular section
- the groove 240 has a substantially triangular section.
- the insert is provided with lateral hooking zones 150, 250 respectively.
- throat sections can of course be chosen according to the desired application.
- FIGS. 9 to 17 illustrate a preferred embodiment of the invention in which similar elements are designated by the same references increased by 100.
- the "grind" shoe 110 of FIG. 9 consists of a sole 120 surmounted by a rod 111, which sole 120 has on its underside a reinforcement for sliding and d wear having a transverse reinforcement part 130 and a longitudinal reinforcement part 140 broken down into two reinforcement parts, respectively front 141 and rear 142 arranged in longitudinal direction on either side of the transverse reinforcement part 130.
- the sliding and wear reinforcement 130, 140 may be in one piece, as shown in FIG. 9, or be made up of two different parts.
- the transverse reinforcement part 130 has a much more complex shape, combining portions of concave cylindrical surfaces in the longitudinal direction and convex in the transverse direction.
- the central area 131 of the transverse reinforcement 130 has, in the longitudinal direction, a rather flat shape, even provided with a very slight concavity oriented downwards, and connected by a radius of curvature more hollow respectively RI, R2 to the longitudinal reinforcement parts respectively 141, 142.
- the central zone 131 also has a substantially planar shape or provided with a slight downward concavity extending laterally by lateral internal lifts, that is to say located on the internal or medial side of the foot -, 132A, and external, - that is to say located on the external side of the foot -, 132B.
- lateral internal lifts that is to say located on the internal or medial side of the foot -, 132A, and external, - that is to say located on the external side of the foot -, 132B.
- 132B are in the form of portions of convex curves of radius of curvature respectively R3, R4.
- the radii of curvature R3, R4 are different on the external and internal sides, the curvature R3 being more pronounced on the internal side. For example, these values are around 30 mm for R3 and 55 mm for R4.
- the side lifts 132A, 132B have a succession of very complex cylindrical surfaces of concave / convex curvature, both in longitudinal and transverse direction which are illustrated more particularly in FIGS. 10 to 13 and 15.
- each of these lateral lifts 132A, 132B has a convex curvature of radius of curvature respectively R5, R6, the curvature of radius R5 being more accentuated, internal side, than the curvature of radius R6 external.
- the radius of curvature R5 can have a value of the order of 50 mm while the radius of curvature R6 has a value of the order of 100 mm.
- Figure 12 illustrates the shape of the side lifts 132A, 132B at their rear area. They are also in the form of portions of cylindrical surfaces of convex curvature with radii of curvature respectively R7, R8 different internal and external side.
- the curvature is always more accentuated on the internal side and the radii of curvature R7, R8 have values of the order of 25 mm for R7 and 80 mm for R8.
- the lateral lifts 132A, 132B have a convex curvature in the transverse direction, always more accentuated on the internal side of the shoe than on the external side, and the radius of curvature of which varies from front to rear.
- the side lifts 132A, 132B on the other hand have a concave curvature in the longitudinal direction as shown in FIGS. 13 and 15.
- the curvature of the internal lateral lift 132A is more accentuated than that of the external lateral lift 132B.
- the respective radii of curvature have values of the order of 65 mm for the radius of curvature R9 of the internal lateral ascent 132A and 80 mm for the radius of curvature RIO of the external lateral ascent 132B.
- FIGS. 16 and 17 show in section the rear ends 142 A and front 141 A respectively of the longitudinal reinforcement parts 142, 141 respectively. These ends 141A, 142A go up towards the upper of the shoe by curves having radii of curvature R11, R12 respectively.
