Definitions
- the present invention relates to a shock-absorbing device particularly for shoes.
- the trauma is caused by the weight of the body, which is suddenly discharged onto the sole of the foot and then inside the structure of the foot.
- the sudden weight discharge is also particularly intense if contact with the ground is violent, as occurs for example in some sports practices, such as volleyball, basketball, athletics, tennis or the like.
- Some form of cushioning of the momentary stress is normally entrusted to a mid-sole made of flexible material in order to prevent prolonged and perhaps particularly violent momentary stresses from causing traumas or internal inflammations of the foot.
- shock-absorbing devices In order to improve cushioning of the momentary stress caused by contact of the foot with the ground, many shock-absorbing devices have been produced and marketed whose function is indeed to absorb the momentary energy when the foot makes contact with the ground.
- two basic shock-absorbing devices can be substantially distinguished.
- a first device entails the insertion in the mid-sole (or even directly in the sole) or association therewith of one or more elastic elements which cushion the momentary stress.
- this device is effective only up to preset momentary stresses; if its intrinsic constructive limit is passed, a packed condition of the device is obtained, wherein its shock-absorbing characteristics are suddenly disabled.
- the packing is also transmitted to the foot as a particularly violent stress, since it forces the sole of said foot to pass from a flexible condition to a condition in which it suddenly rests on a very hard surface.
- Packings in fact usually show up as a particularly quick transition from a flexible situation to a totally rigid situation.
- a second kind of device entails providing cells or chambers wherein a fluid is present, which is adapted, owing to its viscosity characteristics and in association with the flexibility of the walls of the chamber, to absorb the momentary energy during contact of the foot with the ground.
- the principal aim of the present invention is to provide a shock-absorbing device which solves the above-described drawbacks of conventional devices, particularly by providing an effective absorption of the momentary stress of contact of the foot with the ground, whilst avoiding packings or in any case rapid transitions from a condition in which the device is highly flexible to conditions in which sudden stiffenings can occur.
- an object of the present invention is to provide a shock-absorbing device which is particularly effective even in situations in which the momentary stress is particularly short and violent, as occurs for example in sports practices or other activities which entail similar problems.
- Another object of the present invention is to provide a device which can be associated in particular with various mid-soles and can be easily adapted to various shoes.
- Another object of the present invention is to provide a shock-absorbing device which is particularly flexible in its application, so that it can be applied to various and different regions of the insole.
- Another object of the present invention is to provide a shock-absorbing device which has a competitive cost with respect to conventional devices and can be manufactured with conventional technologies.
- a shock-absorbing device particularly for shoes, characterized in that it comprises, included within the mid-sole, at least at a heel region, a plurality of hollow elements made of elastomer and connected by bridges, each of which is internally shaped so as to form, upon assembly, two superimposed chambers which are mutually connected by a duct, said duct having a smaller cross-section than said chambers and forming a constriction for passing air flows.
- a mid-sole generally designated by the reference numeral 10 includes, at the heel and metatarsal regions, two shock-absorbing devices according to the invention, generally designated by the reference numerals 11 and 12.
- each one of the devices 11 and 12 comprises a plurality of hollow cylindrical tubular elements 13 arranged, upon assembly, so that their axis is vertical; the elements 11 and 12 are made of elastomer and are mutually connected by bridges 14.
- the cylindrical tubular elements 13 and the corresponding bridges 14 are monolithic with respect to each other.
- Each one of the cylindrical tubular elements 13 is internally shaped so as to form, upon assembly, two open and superimposed chambers 15 which are mutually connected by a duct 16.
- the duct 16 is substantially axial with respect to the corresponding tubular element 13 and has a much smaller cross-section than the corresponding chambers 15.
- the compression of the upper chambers 15 causes the air contained therein to be transferred, through the duct 16, to the corresponding lower chambers 15.
- the cross-section of the duct 16 is smaller than the cross-section of the chambers 15, it produces a constriction which slows the air flow from one part to the other and damps the energy of the impact.
- the shock-absorbing device according to the present invention while being structurally simple, solves in an excellent and effective manner the problem of cushioning the momentary stress caused by contact between the foot and the ground without however exhibiting unpleasant packing effects or sudden transitions from suitable flexibility to sudden structural rigidity.
- shock-absorbing device is particularly simple to insert in a mid-sole and can be arranged in various and different regions, which correspond to equally various regions of the sole of the foot.
- the device can be applied to different shoes related to the most disparate activities and situations.
- the materials and the dimensions may be any according to requirements.

Abstract
Description
Claims (6)
- A shock-absorbing device, particularly for shoes, characterized in that it comprises, included within the mid-sole, at least at a heel region, a plurality of hollow elements made of elastomer and connected by bridges, each whereof is internally shaped so as to form, upon assembly, two superimposed chambers which are mutually connected by a duct, said duct having a smaller cross-section than said chambers and forming a constriction for passing air flows.
- A device according to claim 1, characterized in that each one of said hollow elements is cylindrical and is arranged so that its axis is vertical with respect to said mid-sole.
- A device according to claim 1, characterized in that said chambers are open.
- A device according to claim 1, characterized in that said hollow elements and the corresponding bridges are mutually monolithic.
- A device according to one or more of the preceding claims, characterized in that said bridges are arranged so as to connect median regions of said hollow elements.
- A device according to claim 1, characterized in that it is located at a metatarsal region of the sole of the foot.
