Definitions

  • the present invention refers to a device for soles of shoes. More precisely, the present invention refers to a device for soles of shoes suitable for increasing the elevation of the user.
  • the present invention refers to a device for soles of gym shoes suitable for increasing the elevation of the user during a sport practice.
  • the present invention refers to shoes, preferably gym shoes, provided with said device suitable for increasing the elevation of the user, particularly during a sport practice.
  • Italian Patent No. IT 1 234 072 discloses shoes equipped with an elastic element able to increase the pulse of elevation propulsion given by the athlete, more precisely by a football player, said elastic element being fastened to the sole of each shoe and longitudinally fixed thereto, at the movement portion of the foot, by means of rivets; the bending undergone by said elastic element results in that it is loaded and causes an additional pulse of propulsion oriented in the motion starting direction.
  • the first spring elastic element could be replaced with a metal foil, for instance having elasticity characteristics variable in the length direction so that, upon contact with the ground, the compression resistance strength would be higher in the middle portion of the shoe than at the tip thereof.
  • US Patent application No. US 2006/0021262 published on February 2, 2006 discloses a device, to be worn bare-foot or onto shoes, able to improve the performance during running or jumping even assuring the balance and the movement control; said device, that has a very complex articulated structure, comprises a contact element with the ground allowing to store energy reusable as propulsive pulse and, in some alternative embodiments, adapters intended however to assure the maximum stability, for instance in a side direction, and not to adjust the device itself depending on the user's weight and/or on the kind of performed activity.
  • German Utility Model Patent No. DE 85 08 599 U1 discloses a shoe, equipped with two soles connected through a leaf spring, suitable for improving a user's performances when running or jumping; the invention claimed in this document aims to reduce the weight of the springs, and consequently the shoe weight, by employing constructive materials lighter than steel though equally flexible such as the fibres-reinforced plastic materials.
  • German Utility Model Patent depicts numerous preferred embodiments, among which a first embodiment optimized for users with weights comprised between 60 and 90 Kg and, therefore, not fit for users with weights lower or higher than said range and a second embodiment providing the use of limiters for the elastic return effect of the springs; however, in none of these preferred embodiments, reference is made to means able to adjust the shoe depending on the user's weight and/or on the kind of performed activity.
  • the shoes provided according to the aforesaid US patent application comprise an elastic and compressible element, for instance a spring, placed between the foot and the ground and embedded inside the sole; the elastic properties of said elastic element are determined by the spring constant k, which allows to take into consideration the user's weight and also the performed sport activity, thus making the elastic element effective in terms of energy storage and release.
  • an elastic and compressible element for instance a spring
  • the object of the present invention is to overcome the disadvantages of the cited known art, meeting the still unsatisfied needs.
  • the device comprising an elastic element, embedded inside each sole, coupled to a movable adapter placed on the front portion of each sole, according to the invention that, advantageously, allows the user to optimally increase his/her elevation, depending on his/her weight and/or the performed activity.
  • the aforesaid device offers the possibility of manufacturing shoes in an assortment variable only in terms of size but otherwise adjustable to users having different weights and/or performing different sport activities.
  • a shoe 1 comprising at least an upper portion, or upper, 2 and a lower portion, or bottom, 3.
  • Said bottom 3 comprises at least a sole 5 and a heel 7, said sole 5 being the part of the shoe in contact with ground and said heel 7 being the support of the shoe at the rear part thereof, that is the support present under the sole at the user's heel.
  • Said shoe 1 further comprises a device suitable for achieving a higher elevation of the user, said device comprising an elastic element 9 and a movable adapter 11.
  • Said elastic element 9 substantially consists of a flexing spring, that is of a foil force-fitted at one end thereof and loaded at the other end.
  • the plane shape of said elastic element 9 can be rectangular, trapezoidal or, preferably, similar to the sole shape in order to increase the spring flexibility without reducing the resistance capacity.
  • said elastic element 9 preferably has a curved profile that, following the profile of the sole, fits the shoe.
  • Said elastic element 9 is embedded inside each sole, more precisely it is embedded in the junction area between said sole 5 and said heel 7, and it progressively diverges from said sole 5 as it proceeds towards the tip of the shoe 1.
  • said elastic element 9 is inserted during the manufacturing stage, before forming the heel, thus being embedded inside the shoe.
  • Said element 9 is preferably made of a metallic material, preferably made of steel; however, other materials can be employed such as, for instance, carbon fibres or other composite materials, in order to obtain better performances together with a smaller overall weight.
  • the lower portion of said elastic element 9, that is the portion in contact with the ground, can be optionally provided with an insole (not shown), having a minimum thickness, to prevent the user from slipping.
  • the elastic element 9 is free at the front portion, but its profile is such as to minimise the distance thereof from the tip of the shoe; anyway, said elastic element 9, even when compressed during the using phase depicted in Fig. 2 , never manages to touch said tip of the shoe.
  • the device able to achieve a higher elevation of the user according to the present invention further comprises an adapter 11 coupled to said elastic element 9, said adapter 11 being placed on the front portion of each sole 5.
  • said adapter 11 is movable, i.e. able to be variably positioned relative to the sole 5, so as to allow the most convenient adjustment depending on the user's weight and/or on the kind of performed activity.
  • the device according to the present invention thanks to the possibility of displacing the adapter 11 at different positions relative to the sole 5, allows to change the stiffness of the elastic element 9 and, consequently, to adjust the shoe depending on the user's weight and/or on the performed sport activity.
  • said movable adapter 11 has a semi-cylindrical shape, with semicircular transversal section and plane longitudinal section; as shown in FIG. 3 , said adapter 11 is provided with a pair of holes 13a, 13b at its ends.
  • Said sole 5 is provided with pairs of holes 15a, 15b, longitudinally arranged with respect to the sole itself, corresponding to said pair of holes 13a, 13b.
  • Said adapter 11 is fastened to the sole 5, for instance through rivets, screws or another known fastening system, so that the pair of holes 13a, 13b of said adapter 11 perfectly couples with a corresponding pair of holes 15a, 15b of said sole 5, said adapter consequently being transversally positioned with respect to said sole 5, the plane portion of said adapter 11 being in contact with said sole 5 and the protruding portion of said adapter 11 being turned towards the outside and, more precisely, towards the elastic element 9.
  • Said adapter 11 can be displaced at different positions with respect to the sole 5 by simply fixing it at a different pair of holes 15a, 15b of said sole 5.
  • the device according to the invention thanks to the possibility of displacing the adapter 11 at different positions relative to the sole 5, allows to change the stiffness of the elastic element 9 as much as one likes, depending on the user's weight and/or on the performed sport activity.
  • the combination of said adapter 11 with said elastic element 9 allows to take the most advantage of the yield of said elastic element 9 since, by changing the position of said adapter 11 along the sole 5, the arm of said elastic element when it is under stress is changed.
  • the adapter 11 when the elastic element 9 is not subjected to pressure, the adapter 11 does not exert any action; when, on the contrary, as it can be seen in FIG. 2 , the elastic element 9 undergoes a high compression, for instance upon jumping, said elastic element 9 is put in contact with said adapter 11, that shortens the arm of the elastic element 9, increasing the stiffness thereof.
  • the user can position the adapter 11 taking into account his/her weight and the kind of push, more or less significant, he/she wants to receive, thus increasing his/her elevation in an optimal way.
  • the positioning operation will be carried out just once, after having bought the shoes, so as to adjust the device to one's own weight and to the kind of athletic performance that one seeks to obtain; however, since the adapter 11 is fixed to the sole 5 in a removable way, the user will be able to modify the position of said adapter in case the conditions of weight ad sport activity have changed.
  • the positioning or re-positioning operation of the adapter 11 can be simply carried out by any user, because it only consists in removing the internal insole of the shoe, in screwing and unscrewing of the fastening system and in reintroducing the insole.
  • Said adapter 11 is preferably made of a metallic material, preferably made of steel; however, other materials can be employed such as, for instance, plastic materials or other composite materials having a high mechanical resistance.
  • the adapter 11 is freely positionable by the user allows to customise the stiffness of the elastic element 9 coupled thereto depending on the user's weight and on the kind of performed sport activity.
  • the adjusting possibility offered by the device according to the invention allows a wide diffusion, at limited prices, of the shoes provided with said device.
  • the device for shoes comprising an elastic element and an adapter according to the present invention, herein disclosed through a preferred embodiment given by way of non-limiting example, can be modified in accordance with ways known to the expert of the technical field without departing from the scope of the present invention; in particular, the systems for embedding the elastic element in each sole and for fastening the adapter, as well as the shape of both the elastic element and the adapter, could be conceived in a way different from those illustrated and, specifically, they could be chosen among the solutions available in the known art depending on the best constructive opportunity.
