Definitions

  • the present disclosure generally refers to a protective device for a heel of a shoe, in particular for a heel of a women's shoe and to a method of protecting a heel of a shoe.
  • heels of women's shoes comprise an end portion and a connecting portion between said end portion and the heel portion of the shoe.
  • the end portion of the heel that is the heel portion that in use during walking comes into contact with the ground, is made of rigid material, resistant to abrasion and impact. Furthermore, being this part of the heel the most stressed one, this end portion is often replaceable. Unlike the end portion, the connecting portion is often made with the same material and with the same finish as the rest of the shoe. It follows that this intermediate portion, or connecting portion, may be made of valuable material, such as for example leather, and of coloured material.
  • the damaged part will be aesthetically irreparably compromised.
  • the present disclosure aims to provide a protection device for a heel of a shoe which allows to overcome the aforementioned drawbacks with reference to the known art and / or to achieve further advantages.
  • the present disclosure starts from the need to provide a protection device for heels which is at the same time easy to install and to remove. Furthermore, advantageously, the heel protection device can also be made of biodegradable material and does not alter the comfort of use and the aesthetics of a shoe with a heel.
  • the protective device for a shoe heel comprises a tubular element configured to be placed onto the heel of a shoe and to adhere to it in a lasting and permanent way without additives or glues.
  • the tubular element can be made of heat-shrinkable plastic or bioplastic material and is configured to shrink around the heel of a shoe following exposure to a heating agent at a temperature between 50 ° C and 90 ° C.
  • the material of the tubular element shrinks at a temperature between 50°C-70°C .
  • the protection device object of the present disclosure is an element in the shape of a tube or hollow cylinder which narrows or contracts, preferably in a radial direction, if exposed to a heat source.
  • the installation of the protective device on the heel of a shoe is particularly facilitated.
  • the relatively low temperature at which the tubular element retracts makes it possible to install the protection device at home using common heating agents, such as for example a hair dryer.
  • the tubular element has a shrinkage ratio between 1.5: 1 and 3: 1, preferably 2: 1.
  • the size of the tubular element prior to exposure to the heating agent is twice that of the tubular element itself following shrinkage.
  • the protection device object of the present disclosure can be used with footwear having heels of different diameters.
  • the tubular element has a wall thickness between 0.1 and 1.0 m (before shrinking).
  • the tubular element is transparent or substantially transparent or translucent. It follows that the use of the protection device according to the present disclosure can be configured so as not to alter the aesthetics of a shoe with a heel. But it can also be coloured, black, or fluorescent or having any other type of finishing depending on the style.
  • the tubular element may have an aspect capable of creating an aesthetic detachment with respect to the heel to which it is applied, to generate a temporary autonomous contribution to the aesthetics of the heel and consequently of the shoe, while maintaining the main purpose of protecting the heel portion for which the invention is proposed.
  • the tubular element comprises a main direction of development which, in use, is arranged substantially parallel to the main direction of development of the heel of a shoe.
  • the tubular element preferably comprises at least one incision (or more longitudinal incisions in a row) which, suitably arranged, facilitates removal of the device once it needs to be replaced.
  • the tubular element is an element made of biodegradable material. Consequently, any dispersion of the protective device during use does not constitute a source of pollution and / or environmental risk.
  • the tubular element comprises a filament, incorporated or applied in the tubular element itself and arranged along the main direction of development of the tubular element, which has greater breaking strength than the tubular element to tear or cut it when the filament is pulled.
  • the present disclosure further relates to a method for protecting the heel of a shoe.
  • This method includes:
  • This step of deforming by heat-shrinking advantageously providing for heating the tubular element to a temperature between 50 ° C and 90 ° C by exposing the tubular element to a heating agent where exposure to this heating agent causes the tubular element to be restricted around the heel of the shoe.
  • the material of the tubular element can be chosen in such a way that the tubular element shrinks when exposed to a temperature between 50° C and 90° C. That is, in such a way that this exposure causes the tubular element to contract, preferably in a radial direction, around a heel of a shoe.
  • this material will be chosen in such a way that this contraction determines the coupling between the protection device and the heel.
  • the installation of the protection device is particularly simplified and simply requires inserting the tubular element on a heel and heating said tubular element, for example by means of a hair dryer, so that the tubular element itself shrinks and adheres to the heel.
  • the tubular element comprises a main direction of development which, when the tubular element is applied to the heel of a shoe, is arranged substantially parallel to a development direction, or vertical direction, of the heel. Furthermore, the tubular element comprises at least one preferential breaking zone, for example an incision or a sequence of notches or a thinning, or a filament arranged along this main direction of development.
  • the method comprises a further step of removing the protective device from a heel of a shoe, in which this removal step is carried out by tearing the tubular element in correspondence with at least this preferential breaking or incision zone.
  • the preferential breaking zone may comprise a plurality of incisions or notches which extend along the entire main direction of development of the tubular element, or a thinned zone.
  • This preferential breaking zone may comprise a thread-like or ribbon-like element incorporated or applied in the tubular element to guide its breaking.
  • FIG. 1 represents a perspective view of a tubular element of a protective device for heels of a shoe according to the present disclosure
  • FIG. 2 represents a view of a security device applied to a heel of a shoe
  • Figure 3 represents a variant of the tubular element of a protection device for heels of Figure 1.
  • an embodiment of a protective device for a heel of a shoe is indicated with the reference number 10.
  • the expression “protective device” means a device configured to be arranged on, and coupled with, the heel of a shoe in order to protect the latter from damage such as abrasion, bumps, scratches and other.
  • the protection device 10 is constituted by a tubular element 1 configured to be slipped on, or coupled with, a heel of a shoe.
  • tubular element 1 extends along a main direction of development L which, in use, is configured to be arranged substantially parallel to a main direction of development, or vertical direction T, of a heel of a shoe.
  • the tubular element 1 is an element that has a cavity A which extends along said main direction of development L.
  • the tubular element 1 comprises a lateral surface 2 configured in such a way as to define a through cavity A inside said tubular element 1 along said main development direction L.
  • the configuration of the tubular element 1 is such that it is possible to slide a heel 11 of a shoe, for example a stiletto heel, within the through cavity of the tubular element 1 itself.
  • the thickness of the tubular element 1, and in particular the thickness of the lateral surface 2 of the tubular element 1, is comprised between 0.1 mm and 1.0 mm (before retraction).
  • the diameter of the tubular element 1 may vary from 0.9 cm to 3.5 cm.
  • the tubular element 1 is preferably cylindrical. Other suitable shapes for passing a heel 11 of a shoe within the through cavity of the tubular element 1 are possible.
  • this tubular element 1 can also have a parallelepiped or cone shape.
  • the tubular element 1 is made of heat-shrinkable plastic or bio-plastic material.
  • the tubular element 1 is made in such a way that exposure to a heat source causes the shrinkage, or contraction, of the tubular element 1 itself.
  • this shrinkage or contraction occurs following an exposure of the tubular element 1 to a heating agent at a temperature between 50° C and 90° C, more preferably between 55° C and 75° C.
  • This exposure causes a shrinking, or contraction, or a size reduction, of the tubular element 1.
  • this shrinking occurs in the radial direction, preferably exclusively in the radial direction.
  • the tubular element 1 shrinks in a direction perpendicular to the main direction of development L.
  • the shrinkage ratio of the tubular element is between 1.5: 1 and 3: 1, and is preferably 2: 1.
  • shrinkage ratio is meant the difference between the size of the tubular element 1 before exposure to the heating agent and the size of the tubular element 1 following exposure to the heating agent.
  • the shrinkage ratio is the ratio between the size of the diameter of the tubular element 1 before exposure to the heat source and following exposure to the heat source.
  • the tubular element 1 of the protection device 10 is made of plastic or bio-plastic material which, in addition to being heat-shrinkable, is resistant to abrasion and impact.
  • tubular element 1 is made of polymeric materials with biaxial orientation.
  • polymers obtained from fossil sources can be used, such as polyolefins (PE (BOPE), PP (BOPP), PS (BOPS)), vinyl polymers (PVC, PVAc , EVOH, EVA), polyesters (PET or BOPET) or polyamides (PA or BOPA, especially Ny6-based), which have the advantage of being very resistant.
  • biopolymers obtained partially or totally from renewable sources are preferably used, such as some polyolefins (bio -PE or bio -PP), some polyesters (bio - PET, PLA or BOPLA, PEF, PHB, PBAT, PBS, PBSA) or some cellulose derivatives (cellulose acetate CA, cellulose acetate propionate CAP, cellulose acetate butyrate CAB), or any other plastic or bio-plastic material that shrinks at relatively low temperatures (50-90° C).
  • bio-PE or bio -PP some polyolefins
  • some polyesters bio - PET, PLA or BOPLA, PEF, PHB, PBAT, PBS, PBSA
  • some cellulose derivatives cellulose acetate CA, cellulose acetate propionate CAP, cellulose acetate butyrate CAB
  • any other plastic or bio-plastic material that shrinks at relatively low temperatures (50-90° C).
  • the installation of the protection device on a heel 11 of a shoe is particularly simplified.
  • to place the heel protection device 10 on a heel 11 of a shoe it is sufficient to place the tubular element 1 around the heel 11 of a shoe, or to insert the heel 11 into the tubular element 1, and subsequently to heat said element tubular 1 at a temperature between 50° C and 90° C in such a way as to cause a shrinkage, or a decrease in the radial dimension, of the tubular element 1 which in turn determines the coupling between the protection device 10 and the heel 11 of the shoe.
  • the tubular element 1 of the protection device is made of plastic or bioplastic material which, once inserted on a heel 11 of a shoe and exposed to a heat source, shrinks around the heel 11 itself so as to adhere to it and remain autonomously integral with the heel 11 itself.
  • the tubular element 1 narrows around a heel 11 of a shoe following exposure to the heat source, it remains in position without the aid of further attachment means.
  • it is not necessary to use adhesives which could damage the shoe itself upon removal of the same protection device.
  • the tubular element 1 can also be made of biodegradable material. It follows that an eventual detachment of the protective device 10 from a heel 11 of a shoe during normal use and the consequent possible dispersion of the protective device 10 in the environment do not constitute a cause of environmental pollution.
  • the tubular element 1 preferably further comprises at least one incision 3 or, more generally, a preferential breaking zone, arranged along the lateral surface 2, for example according to the main direction of development L of the tubular element 1.
  • the tubular element 1 comprises a plurality of incisions 3 which preferably extend for the entire length of the main development dimension L.
  • this at least one incision 3 facilitates the removal of the heel protection device 10.
  • the at least one incision 3 of the tubular element 1 facilitates the breaking of the tubular element 1 itself along the main direction of development L.
  • Each preferential breaking zone may be defined by or comprise a thread-like or ribbon-like element , or filament, incorporated or applied in the tubular element which, with reference to Figure 1, may extend along the dotted line identified with reference 3.
  • the thread-like or ribbon-like element, or filament advantageously will have a greater breaking strength than the tubular element 1 , so as to be used to tear or cut the latter.
  • the thread-like or ribbon-like element, or filament will be arranged in the tubular element in such a way that its pulling determines the cutting or tearing of the tubular element 1 where this is affected by the presence of the thread-like or ribbon-like element itself.
  • the thread-like element or ribbon-like, or filament preferably will be made of transparent material and advantageously will be inserted into the device in order to make the removal of the device effective and easy.
  • the thread-like or ribbon-like element, or filament will be made of a material having greater tensile strength than the material of which the tubular element 1 is composed.
  • the thread-like or ribbon-like element, or filament will be made of the same material of which the tubular element 1 is composed but will have a greater thickness so as to be able to tear the tubular element 1 without breaking when it is pulled.
