Definitions

• the present invention relates to a slipper adapted to the practice of classical dance and intended in particular for dancers in dance school or professional dance performance dances.
• slippers traditionally used by ballet dancers essentially comprise a sole, as a rule, of leather to which is attached a soft slipper top, in particular satin, and a point constituted by a hard shell or box surrounding the toes and which extends through a stiffening shank to the lower part of the foot extending into the arch.
• the present invention relates to a slipper adapted to the practice of classical dance of the above-mentioned type, characterized in that the shank is equipped, on its underside that is to say on the ground side, with at least two incisions. transverse, of a depth of about half a thickness; such incisions, which are generally located at the level of the plantar pads, are normally closed when the foot is flat or pointed and open when the foot is set for walking or running.
• This shank is usually pierced with small holes regularly spaced to let the sweat.
• the incisions make it possible to guarantee the rigidity of the shank in one direction, but give the sock a certain degree of flexibility in the opposite direction insofar as they have the characteristic to open at the time of the unwinding of the step and to close at the moment where the dancer goes flat and spiked.
• the liner according to the invention thus has the advantage of allowing a certain degree of flexibility to be obtained when the dancer is walking and descending from the tip to the half-point, a flexibility that the traditional tips do not have. not.
• the shape of the shank, its holes, its length, the position and the number of grooves of the dance shoe according to the invention are of course adapted to the morphology of the dancer to whom this shoe is intended.
• the shank is made of a resin such as polyacetal, polyamide, polypropylene, polyimide ... optionally reinforced with synthetic or natural fibers (flax, hemp, kevlar ).
• the box, in its lower part and the shank are constituted by two separable pieces, preferably They can be clipped onto each other, possibly both made of a synthetic material.
• the dancer can thus easily separate the box and the shank from her slippers and thus choose, adjust or replace them according to her morphology and in particular her size, the points of support of her arch or even his strength.
• the shank of the dance shoe according to the invention can also be glued to be secured to the box and made of a traditional material (composite of natural fibers bound by collars).
• the box is coated at its inner part, at the level of the toes of the dancer in a point position, with an elastomer material or an open-pore foam. or sphagnum to cushion shocks and to capture and let sweat pass.
• the box of a ballet slipper does not have a uniform stiffness on the whole of its surface; it is indeed particularly hard at its front end, at the platform, that is to say its surface contact with the ground when the dancer is spiked as she refined and becomes more flexible at its lateral edges or wings and the upper part of the upper where it is necessary to respect the flexibility of the toe area.
• the density or nature of the material of the inner part of the box should preferably vary so as to allow these requirements to be met.
• This material must in particular be very resistant to pressure at the platform so as not to hinder the balance of the dancer and allow him to feel his support.
• viscoelastic material buffers whose function is to distribute the pressure in the areas where the supports are the most important and tend to create irritations on the skin that cause corns or blisters.
• tampons placed in painful places, do not prevent the evacuation of perspiration. They will be for example microperforated if one does not choose materials consisting of open pore foam.
• the box may also advantageously be microperforated.
• the "skeleton" of the box of the dance shoe according to the invention is made of synthetic material, it is preferably dressed and reinforced with a satin lined with an elastic fabric and then glued to this structure so as to obtain a satisfactory aesthetic and to avoid satin folds.
• the box is made of a resin whose softening point is below a temperature of 100 ° C. and, if possible, 40 ° C.
• the dancer Given the presence of the "skeleton" synthetic material low softening point, the dancer can perfectly adapt the box of her shoes to its morphology by modeling it precisely to the shape of her feet by heating in the oven or hair dryer or in the microwave.
• Another disadvantage of traditional dance shoes is related to the noises emitted during their impact on a surface such as a scene that can be very annoying during shows.
• Such noises are more particularly caused by the knocking of the box on the floor during the race of the dancers (flat feet), but also during jumps on spikes.
• Another object of the present invention is to overcome this disadvantage.
• the box is coated at its outer part with a noise-reducing pad, especially in the space between the leather sole and the underside of the platform. form (part where the folds are).
• This pad is made of elastomer or foam; such a skate, which is interposed between the box and the material that dresses the slipper (satin, leather, synthetic ...) allows to reduce to a large extent the noise caused by the impact of the box on the floor on which evolve the dancers.
• Another disadvantage of traditional dance shoes is related to the risk of tendon injury in the heel, caused by the presence in the back of the stem of a lace housed in a sheath.
• the rod is equipped at its rear part, at the heel of the dancer, a preformed braid which distributes the force on a part more wide of the heel.
• a strip which must be very resistant and inelastic is generally specially woven and includes very strong and non-elastic fibers Kevlar type included.
• the lace conventionally present inside the border of the stem, at the heel which presses very hard on the rear part of the waist and which can provoke tendinitis, can thus be removed and replaced by the lace which is sufficiently wide so that the possible cuts only relate to areas of low demand.
• FIG. 1 is a bottom view of a dance shoe according to the invention
• FIG. 2 is a cross-section of FIG. 1 along axis II II;
• FIG. 3 is a view from below of the tip (assembled box and shank) of a dance shoe according to the invention
• FIG. 4 is a section of the tip shown in Figure 3 along the axis IV IV.
• the dance shoe which is the subject of the invention is essentially constituted by a sole 1 and a rod 2 and a tip 3 (box and shank assembled) which is shown more precisely on Figures 3 and 4.
• the sole 1 is made of leather more or less thick.
• the rod 2 is made of a flexible material such as satin, leather, alcantara; it covers the front of the dancer's foot and extends on both sides of the kick to bypass the heel.
• the front of the rod 2 is rigidified by the tip 3 which is made of a synthetic material.
• the tip 3 is itself constituted by two separate parts clipped on one another, namely a box 4 which surrounds the toes of the dancer and a stiffening shank 5 extending it; the shank 5 is located at the lower part of the dancer's foot above the sole 1 ( Figure 2).
• the shank 5 is equipped at its front end with elastically deformable hooks 6 engaging in corresponding recesses in the box 4.
• the shank 5 is equipped on its underside with two transverse incisions about half-thickness 7 which ensure its rigidity in one direction but give it a degree of flexibility in the opposite direction to facilitate walking of the dancer.
• the box 4 is coated at its inner part, at the level of the toes of the dancer in a point position, with a foam 8 with open pores or with an elastomer perforated with small holes coated with fabric so as to allow the sweat to pass.
• the outer part of the box is coated with an anti-noise pad 9.
• the rod 2 is equipped at its rear part with a preformed strip 10 whose function is to prevent the risk of cutting at the heel of the dancer.
