Definitions

  • the present invention relates to an insole for sports shoes of the type comprising a shell and a sole made of plastic material, such as for example a ski boot, a Telemark boot, a roller skate or an ice skate or a trekking boot.
  • Today these shoes are usually constituted by a shell made of plastic material to which an upper is articulated and which is provided with a sole which, in the case of ski boots, is of the standardized type, provided with a toe unit and a heel unit which have standardized dimensions.
  • plastic material makes it possible to have a shoe that is rigid enough for the foot, arranged inside it with the interposition of a soft innerboot, to be able to transmit in an optimum manner the forces to the sports implement, such as the ski or the rollers or an ice skating blade.
  • mechanoreceptors which are corpuscles that inform the central nervous system and determine how the muscle chains must be tensioned.
  • Mechanoreceptors are distributed more or less all over the body: under the skin, in joints, ligaments, tendons and muscles, and signal to our central nervous system pressures, vibrations, torsions, frictions and the relative position of one part of the body with respect to the other.
  • Mechanoreceptors are different in terms of shape and specialization; some of them have the appearance of tiny grapes, the compression of which during walking activates an electrochemical signal toward the brain; they measure from a few thousandths of a millimeter to a few millimeters and are far more numerous in the feet and hands than elsewhere; they are also connected via nerves to the central nervous system.
  • An essential condition for being able to exhibit first-choice muscular activity is that the signals that reach the brain must be strong and clear, otherwise the movements are not of good quality (kinetic harmony versus kinetic disharmony).
  • the nervous system is unintentionally fooled by this information; the symmetry of shoes and the difference in our feet cause the nervous system to interpret for years the difference in pressure applied by the shoes as a true weight displacement even if we are not moving and alerts the muscle chains for a movement action that is not occurring.
  • the nervous system responds automatically to the stimuli that it receives and does not comment on them.
  • One shoe can thus compress the foot more than the other one in terms of length, width, at the big toe, on the metatarsal region: these sensory differences, maintained for years, are sufficient to perpetuate unnecessary and "misleading" muscle tensions and, with the complicity of the movements that we perform, set our posture asymmetrically (a shorter leg, a lower hip, a higher shoulder, the head tilted).
  • shoes such as spike shoes for athletics, with studs for soccer, or ski boots that are not adapted correctly, can create the above-mentioned severe musculoskeletal problems in addition to making the movement imprecise.
  • CH 688 637 is also known which describes a ski boot which comprises a shell made of plastic material which comprises a sole that has a flat surface for resting on the ski, a plantar insert being arranged inside the shell and inside a soft inner shoe; the plantar insert has, on its lower surface, protrusions or plates which are located in the regions of the heel and of the first and fifth metatarsal bones.
  • the aim of the present invention is therefore to solve the noted technical problems, eliminating the drawbacks of the cited background art and, by devising an insole for sports shoes that is capable of allowing the user to adapt the shoe in the various situations of use to his most correct posture both on the frontal plane and on the sagittal or lateral plane, complying with the tibiofemoral angle that is most physiological for said athlete.
  • an object of the invention is to provide an insole for sports shoes that allows an adaptation of the posture of the user already in the static phase prior to sports action, in order to find his best center of gravity.
  • Another object of the invention is to obtain an insole for sports shoes that improves laterally the return of the user onto the blades.
  • Another object is to obtain an insole for sports shoes that is structurally simple, has low manufacturing costs and can be provided by means of common known systems.
  • an insole for sports shoes comprising a shell and a sole made of plastic material, characterized in that it has, in a lower region, means adapted to allow the controlled transverse tilting of said insole with respect to said sole.
  • elastically deformable means which are interposed between said insole and said sole and are adapted to control the extent of said tilting.
  • an insole 1 is particularly usable for sports shoes for example of the type constituted by a ski boot 2, a skate or a trekking boot, comprising a shell 3 and a sole 4 made of plastic material.
  • the insole 1 is provided in a lower region, at the heel region 5 and at the metatarsal region 6, respectively with a first seat 7 and with a pair of second seats 8a, 8b for elastically deformable means which are adapted to allow the controlled transverse tilting of said insole with respect to such sole.
  • a hollow pivot 9 protrudes at the first seat 7 provided in the heel region 5 approximately centrally thereto and is provided with a frustum-like shape in which the vertex is directed away from the lower surface of the insole 1 and has, at a diametrical plane that substantially coincides with the longitudinal axis of the insole 1, a pair of openings 10a, 10b which are adapted to define a pair of elastically deformable wings 11a, 11b.
  • the pivot 9 has such a length as to protrude, with its end 12, beyond the first seat 7.
  • the end 12 of the pivot 9 is inserted at a complementarily shaped and axially provided third seat 13 of a pad 14, which is made of elastically deformable material and is such as to allow the transverse tilting of the insole 1 under the weight of the user.
  • the pad 14 is accommodated at an adapted fourth seat 15, which is provided at the heel region 5 of the sole 4.
  • the pad 14 is arranged within the fourth seat 15 so that it cannot move under the force of the pin 9, the end 12 thereof being spaced from the bottom 16 of the fourth seat 15.
  • An insert 17 is arranged coaxially with the pivot 9 which is also made of elastically deformable material, preferably with a lower elastic constant than the pad 14.
  • the insert 17 has an essentially cylindrical shape and is interposed between the lower surface of the insole and the pad 14; the insert 17 has a first end 18 which has a preferably circular plan shape and can be positioned at a fifth seat 19 which is provided coaxially to the pivot 9 at the first seat 7.
  • the first end 18 is perforated axially for allowing the passage of the pivot 9 also at the third seat 13 provided in the pad 14.
  • the insert 17 is provided in a lower portion, on two opposite sides which are preferably arranged transversely to the heel region 5, with a pair of feet 20a, 20b, which are adapted to rest at the perimetric edge 21 of the underlying pad 14.
  • Such pad advantageously has an axial protrusion 22 that affects partially the opening provided in the insert 17.
  • Figure 4 is a sectional view, taken along a plane that is transverse to the heel region 5, of the insert 17, which exhibits an essentially cup-like shape and whose first end 18 again interacts with the first seat 7; the insert 17 has, at the sides not affected by the pair of feet 20a, 20b, a C-shaped transverse cross-section in which the perimetric end edge 17a faces the perimetric edge 21 of the underlying pad 14.
  • the annular ridge 23 has such an extension as to keep it, in the condition of non-use of the shoe, at a desired distance from an underlying flat surface 24 that is present at the facing internal surface of the sole 4 that is adjacent to the bottom 16.
  • a pair of disks 25a, 25b can be arranged at the second seats 8a, 8b, which preferably have a circular shape in plan view and also are made of the same material of which the pad 14 is made.
  • the disks 25a, 25b can be placed at complementarily shaped sixth seats 26 which are obtained at the vertex of adapted supports 27 that protrude from the bottom of the sole 4.
  • the supports 27 may be optionally omitted.
  • the illustrated solution utilizes laterally the flexing of the wings 11a, 11b of the pivot 9 and of the pad 14 and of the insert 17, which are capable of storing elastic potential energy and of returning it, thus loading energetically the insole and ensuring an elastic return for the user.
  • Figures 6 to 8 illustrate a variation in which the end 112 of the pivot 109, which is axially hollow, is inserted in a complementarily shaped third annular seat 113, which is provided axially to a pad 114 that is made of elastically deformable material and is such as to allow the transverse tilting of the insole 101 under the weight of the user.
  • the pad 114 is T-shaped so as to form a first base 114a, which is directed towards the sole 104, and a first axial stem 114b, which is adjacent to the third annular seat 113 and can be inserted within the pivot 109.
  • the height of the first stem 114b and the depth of the third seat 113 are such that in inactive conditions the end 112 of the pivot 109 does not interact with the bottom of the third seat 113 and the end of the first stem 114b does not interact with the bottom of an overlying fifth seat 119 which is provided coaxially and externally with respect to the pivot 109 at the first seat 107.
  • the pad 114 is accommodated at an adapted fourth seat 115 which is provided at the region 105 of the heel of the sole 104.
  • the first base 114a of the pad 114 is arranged within the fourth seat 115 so that it cannot move under the force of the pivot 109.
  • An insert 117 made of elastically deformable material, preferably with a lower elastic constant than the pad 114, can be associated coaxially and externally with respect to the pivot 109.
  • the insert 117 is essentially T-shaped, with a second flat base 117a which is directed toward the underlying pad 114, and a second stem 117b, which is perforated so as to accommodate the pivot 109 inside it.
  • the hole that affects said second stem 117b continues to affect the entire thickness of the second base 117a.
  • the second stem 117b has a first end 118 which has a preferably circular plan shape and can be positioned at the fifth seat 119.
  • the insole 101 is provided in a lower region, at the metatarsal region 106, with second axially perforated seats 108a, 108b, in each of which it is possible to arrange rotatably the third stem 108c of a disk 125a, 125b.
  • Each one of the disks 125a, 125b is shaped so as to form a pair of studs 128a, 128b, also made of the same material or of a different material with respect to the one of which the pad 114 is made.
  • the disks 125a, 125b can be arranged at complementarily shaped sixth seats 126 obtained at the bottom of the sole 4.
  • the height of the two studs 128a, 128b is different, so that upon a rotation of the disks 125a, 125b it is possible to achieve, as indicated in Figure 8 , a different distance of the insole 101 from the sole 104.
  • the invention furthermore allows an adaptation of the posture of the athlete already in the static phase, prior to athletic action, in order to find his best center of gravity; this can be achieved with an adjustment system that acts both on the heel and on the forefoot.
  • the described solution allows the base of the foot to oscillate laterally (not freely so that it is not perceived) under the effect of the weight force of the athlete, adapting the relationship between the sole and the lower limb to the athlete and increasing the return to the balanced position by utilizing such elastic energy.
