Definitions
- the present invention relates to the field of athletics.
- Studded shoes have studs, implanted under the sole, allowing the athlete to grip / grip the track better, and thus increase their performance.
- An athletic spike is a technical shoe which generally has 5 to 8 cavities under the outsole into which sharp nails are aimed. These studs are intended to improve grip on the athletics track.
- the location of these studs may be different depending on the model and the discipline for which they are suitable. Their length can also vary depending on the use, for example from 6 mm to 15 mm.
- the present invention relates to a protective shell (100) for a shoe with nails (200) comprising a front part and a rear part, the front part being able to be equipped with nails, the shell (100 ) comprising a sole (110) comprising a front part (101) and a rear part (102). Furthermore, the front part (101) and the rear part (102) of the shell (100) are configured to cooperate with the front part and the rear part of the shoe with nails (200) respectively, and the shell (100) further comprises: a peripheral rim (120), integral with the sole (110), a peripheral cable tightening device (160), integrated with said peripheral rim (120).
- the shell further comprises a cushion (130), positioned in the front part of the shell (100).
- transverse stop (103) separating the front part (101) and the rear part (102) of the shell (100), and serving as a stop in translation for the cushion (130).
- the shell (100) can have a concave shape (106) which matches the arch shape of the arch of the foot.
- clamping device to further comprise:
- a tightening knob (140) comprising a toothed wheel and a non-return pawl.
- clamping device may comprise a clamping knob (140); and wherein the clamping wheel (140) also includes a release device which includes at least one of:
- the present invention makes it possible to protect the nails under the shoes with nails, just like the rear part of the shoes with nails, to move off the athletics track with tiptoes.
- the present invention also allows, thanks to its clamping device, the same shell to be adaptable to several shoes, whether in size, shape or model.
- a shell according to the invention protects not only the nails but also the heel of a shoe with nails, which allows natural walking and comfort.
- the present invention can be implemented for all athletic disciplines requiring nails on the front part of the foot, for example: sprinting, hurdles, long jump, triple jump, pole vault and the middle distance.
- the present invention can also be implemented for bobsleigh shoes.

- FIG. 9 illustrates a cross section of a shoe with nails in one embodiment of a shell according to the invention.
- FIG. 1 An embodiment of a shell 100 according to the invention is illustrated in Figure 1.
- the shell 100 comprises a flexible material.
- the material of the shell 100 is elastic.
- the shell 100 comprises a sole 110.
- the shell 100 also includes a peripheral rim 120, secured to the sole 110 by the peripheral contour thereof.
- peripheral rim 120 and the sole 110 are made of the same material, preferably an elastic material.
- the shell 100 is based on an elastomer, ethylene vinyl acetate, or rubber.
- the shell 100 is a polyurethane thermoplastic elastomer whose Shore hardness scale is equal to 60, which makes it possible to adapt the shell 100 to different shapes of shoes with nails.
- the thickness of sole 110 is substantially constant.
- the sole 110 is solid, that is to say free of holes and made of a waterproof material.
- the sole 110 is solid, that is to say free of holes and made of a waterproof material.
- the sole 110 has an outer face 111, intended to be in contact with the ground, whatever the coating (track, concrete, etc.), and an inner face 112, intended to be in contact with shoes to nails and a cushion 130 described later.
- the outer face 111 is flat.
- the sole 110 has a front part 101 and a rear part 102.
- the front part 101 corresponds substantially to the part of the foot which is located in line with the metatarsals and the phalanges of the toes.
- the rear part 102 substantially corresponds to the other part of the foot, that is to say from the heel to the arch of the foot inclusive.
- the front part 101 and the rear part 102 are separated from each other by a transverse abutment 103.
- the transverse abutment 103 is molded with the shell 100, see in particular Figure 6 .
- the shell 100 also incorporates a cushion 130, positioned in the front zone of the sole 110, and covering the entire latter.
- the material and the thickness of the cushion 130 are chosen so that, when a shoe with nails 200 is positioned in the shell 100, the nails 201 of the shoe with nails 200 come into abutment on the cushion 130 or in the latter, without touching the inner face 112 of the sole 110, as shown in Figure 9.
- the cushion 130 absorbs the mechanical energy of the studs 201.
- the cushion 130 does not degrade the nails 201 , i.e. the cushion 130 does not dull the nails 201.
- the cushion 130 is made of flexible and soft material. It can be made in a synthetic foam.
- the cushion 130 is made of thermoplastic elastomer material, more precisely a styrene-butadiene-styrene (SBS) or styrene-ethylene/butylene-styrene (SEBS) block copolymer.
- the cushion 130 has a low hardness scale, that is to say less than or equal to 20 on the Shore hardness scale, and in this case a value equal to 5 on the Shore hardness scale. .
- the cushion 130 is positioned in force in the front part 101 of the sole 110. It is held in position in abutment against the transverse stop 103 and the peripheral rim 120.
- the transverse stop 103 makes it possible to prevent the cushion 130 from sliding from the front part 101 of the shell 100 towards the rear part 102 thereof.
- This variant makes it possible to change the cushion 130 very easily if it deteriorates.
- the cushion 130 is held in the front part 101 of the sole 110 by means of repositionable attachment means, for example a hook-and-loop closure, typically a textile hook and loop closure, known in particular under the registered trademark "Velcro", part of which, for example that comprising the hooks, is integral with the front part 101 of the sole 110, in this case by gluing on its upper face; and the other part of which, for example that comprising the textile loops, is secured to the cushion 130, in this case by gluing, to the underside of the cushion 130.
- This variant also makes it possible to change the cushion 130 very easily if it is this deteriorates and to adapt the position of the latter in the front part 101 of the sole 110.
- the cushion 130 is held in the front part 101 of the sole 110 by means of an adhesive.
- Cushion 130 makes it possible to adapt to all tip implantations.
- the front part 101 of the sole 110 and the transverse abutment 103 define a space in which the cushion 130 is inserted.
- the space for inserting the cushion 130 of the protective shell 100 for the left shoe has the same shape and the same dimensions as the space for inserting the cushion 130 of the protective shell 100 for the right shoe.
- the same cushion can be inserted indiscriminately into a protective shell 100 for the left shoe or for the right shoe.
- the cushion 130 has a contact surface with the nail shoe 200 substantially flat.
- the cushion 130 may comprise a set of recesses, preferably non-through holes or grooves or gutters (not shown).
- the recesses are made in the upper face of the cushion 130, opposite to that in contact with the sole 110.
- the recesses can be in the form of circular, square, oblong holes, or grooves. They are configured so that when a shoe nails 200 is positioned in a shell 100, each nail 201 thereof comes to the right of a recess.
- each nail 201 "sinks" into a recess. Provision may be made for the depth of the recesses to be equal to the length of the nails 201. A safety margin may also be provided. In this case, the depth of the recesses is equal to the length of the nails 201 plus the safety margin, in this case equal to 20%.
- the peripheral rim 120 is preferably substantially perpendicular to the sole 110, with the exception of the arch of the foot where the peripheral rim 120 matches the shape of the arch of the foot. .
- the peripheral rim 120 also matches the shape of the heel, which facilitates the donning of the shell 100 on the shoe with nails 200 and the removal of the shell 100.
- the peripheral rim 120 has a cant 104 at the level of the toes, so as to create an abutment against which at least one of the toes can come, which facilitates walking and maintaining the shell 100 on the shoe with nails 200, as illustrated in particular in figure 9.
- the peripheral rim 120 has a substantially constant height on the lateral sides, and in this case less than 2 cm, and a height less than or equal to 5 cm at the heel, as illustrated in Figure 2 .
- the peripheral rim 120 leaves free: the instep, the part corresponding to the metatarsus and the front part of the ankle; that is to say that the peripheral rim 120 does not cover any of these parts, which facilitates both the handling of the shells 100 and the shoes with nails, that is to say putting on and removing the shells 100 from the shoes with nails, and walking.
- the shell 100 also includes a clamping device.
- the clamping device can adopt at least the following two positions: a release position in which the shoe with nails 200 can be inserted into the shell 100 or removed therefrom, and a clamping position in which the shoe nail 200 is held in the shell 100.
- the tightening device comprises a cable 160, or lace, which allows tightening of the shell 100 on the shoe with nails 200, thus allowing the shell 100 to hold hooked to the shoe with nails 200 when the cable 160 is tense.
- the cable 160 is peripheral, and thus has a curved shape around the foot, without passing over the foot, without zig zag.
- the clamping device also comprises a cable locking element 160, to lock the latter in the clamping position.
- the clamping device comprises a stopper, also called cable clamp 160 or cable block 160 known for example in the field of donrdashery, in particular at the following address https://www.lamerce-riedescreateurs .fr/haberdashery-and-accessories/5268-block-cordon-metal- nickle.html.
- the cable lock 160 comprises a through hole, a stopper and an elastic element, in this case a spring, integral with the stopper. At least one strand of the cable 160 passes through the through hole and the return force of the spring makes it possible to block the cable 160 in translation, which is known for example in the field of compression bags equipped with a drawstring.
- the tightening device comprises a tightening wheel 140, positioned at the rear of the shell 100, at the level of the heel, mechanically fixed in a housing 105 provided for this purpose, for example by overmolding or by gluing.
- the tightening wheel 140 winds the cable 160 by turning it in a predetermined direction, which tightens the cable 160 around the shell 100. It comprises for this purpose a toothed wheel and a non-return pawl.
- the tightening wheel 140 also comprises a release device, to release the cable 160 from the tightening wheel 140.
- the rotation in a predetermined direction of the tightening wheel 140 makes it possible to tighten the cable 160, and the rotation of the tightening wheel 140 in the other direction makes it possible to loosen the cable 160.
- the loosening is implemented using a set of at least one crank.
- the release device comprises a first crank 141, the actuation of which allows the cable 160 to be completely released from the clamping wheel 140, in this case by completely releasing the anti-return pawl of the toothed wheel. It is possible to provide that the release device also comprises a second crank 142 whose actuation makes it possible to release the cable 160 from the tightening knob 140 in increments, in this case by raising the anti-return pawl in increments, which allows adjustment end of tightening. In this case, each increment corresponds to one tooth of the toothed wheel.
- the cable 160 in this case a stainless steel fine lacing cable 160 impregnated with a nylon, is fixed to the shell 100 via eyelets 150 integrated into the shell 100 and through which the cable 160 passes.
- the lacing, or tightening, of the cable 160 tightens the shell 100 on itself in its width and in its length.
- the tightening wheel 140 is located on the rear vertical face of the hull 100.
- the cable 160 is installed on the periphery of the hull 100, all around it.
- a set of peripheral eyelets 150 are provided, integrated into the shell 100.
- a groove can also be provided in the shell 100 to facilitate tightening of the cable 160.
- the lacing that is to say the tightening of the cable 160 increases the curvature of the shell 100. This undergoes a flexible deformation, a contraction of the order of 20 mm in length, and 5 mm in width according to tests by the applicant.
- the same shell 100 can be used for several sizes of shoes with nails, in this case 3 consecutive sizes.
- the eyelets 150 are made for example by plastic injection.
- the eyelets 150 are positioned in the upper part of the peripheral flange 120 and over the entire length thereof.
- At least one eyelet 150 is provided at the cant 104 of the peripheral rim 120, as illustrated in particular in FIG. 3.
- the inner part of the foot has the shape of an arch at the level of the arch of the foot.
- the shell 100 has a concave shape 106 which matches the shape of the arch, see in particular figure 8.
- eyelets 150 are provided, in this case 3 eyelets 150, or 1 large curved eyelet 150, to match the arch shape of the arch of the foot, which makes it possible to increase the support of the shell. 100 on the 200 nail shoe while walking.
- the shell 100 is free of strap on the foot, or webbing strap on the heel, which not only facilitates the use of the shell 100, but also protects the foot from the user by limiting the risk of cuts.
