Definitions

  • This invention relates to a heel-bearing footbed device for footwear with reinforcement of composite material.
  • the invention finds particular, but not exclusive, application in the field of footwear production industry, and accessories and components thereof, particularly in the feminine footwear production industry producing feminine footwear provided with heel or wedge heel.
  • Footwear whose essential structure comprises at least one upper for wrapping up the upper portion of the foot, and an appreciably rigid portion made up by the sole and, if necessary, a heel, for at least partially contacting the ground, are known and used for a long time.
  • a raised portion placed at the heel known as heel or wedge heel, allows keeping the hind foot elevated compared to the forefoot.
  • the insole consists of an assembly comprising two reciprocally connected portions, of which one first front portion coincides with the area of the foot including the toes and a portion of the metatarsus, and a second back portion coincides with the area of the foot including the metatarsus and the tarsus.
  • the back portion of the insole coinciding with the area of the foot including the metatarsus and the tarsus has to present constructional features of rigidity and resistance, such as to counteract all the stresses imparted by the weight of the body and by walking movements, and such as to allow the appropriate anchoring of the upper and heel or wedge heel, usually by using known retaining means.
  • a suitably shaped and sized insole is provided, usually called footbed, structured such as to give and ensure the needed characteristics of support and rigidity to the shoe.
  • the structure of the insole is made, for the forefoot, of flexible materials such as, by way of example, fibre cardboard, Texon, or flexible plastic materials, and for the hind foot portion, which should have greater characteristics of rigidity, of coupled materials, among which, by way of example, fibre cardboard coupled to Texon or fibre cardboard coupled to Texon by interposing a metal sheet known as shank, or, furthermore, made of thermoplastic materials incorporating a metal shank.
  • flexible materials such as, by way of example, fibre cardboard, Texon, or flexible plastic materials
  • hind foot portion which should have greater characteristics of rigidity, of coupled materials, among which, by way of example, fibre cardboard coupled to Texon or fibre cardboard coupled to Texon by interposing a metal sheet known as shank, or, furthermore, made of thermoplastic materials incorporating a metal shank.
  • D1 describes a reinforcing device, shank, for a shoe sole, in short comprising a body consisting of a strip of given length and thickness, as well as a bent surface, being provided with an enlarged portion in a longitudinal end portion, the reinforcing body being provided with at least one suitable rib, furthermore the thickness of the reinforcing body being thinner at one end.
  • the reinforcing body is made of resin.
  • D2 describes a solution for footwear soles and the production method thereof, said footwear soles having a forepart and a back part, wherein a reinforcement, made of thermoplastic composite material reinforced with fibres, is placed in said back part, said reinforcement being placed between two laminas consisting of the same material of the footwear sole, and being coupled by means of adhesives. Furthermore, it is provided that the material constituting the soles is heated, while being held in a metal form having a temperature lower than the temperature of the sole material, such as to carry out a complete adhesion.
  • D3 in short describes an assembly sole for assembling footwear of the type wherein an upper is folded and fixed under the sole.
  • the sole includes a support base having a thermo-melting adhesive on the lower side, so that the upper can adhere to the sole by heating.
  • the sole preferably includes a shank placed above the support base, and a reinforcement above the shank, in order to form a single body.
  • the invention includes a shoe assembled on the sole.
  • a first limitation to the known solutions for heel-bearing footbed consists in that said footbed solutions do not have a high degree of rigidity, so that, in particular when the heel is very high, there is a considerable risk of the heel breaking or detaching from the footbed, as the related footbed structures of the known solutions are not, in any case, adequately rigid.
  • a heel-bearing footbed device (1) for footwear with reinforcement of composite material comprising a reinforcing body (4) made of composite material, particularly of composite material of carbon fibre and/or Kevlar and/or glass fibre, or of composite material of carbon fibre according to the teaching disclosed in Patent Application n.TV2009A000029 (Rampin), the reinforcing body (4) of composite material being totally or partially covered by a covering shell (5) of thermoplastic or thermo-hardening material, the reinforcing body (4) including suitable slots (41 a, 41 b) for facilitating the positioning of fixing means for the other elements forming the shoe, which are usually assembled to the heel-bearing footbed portion.
  • a first advantageous scope is that of obtaining a heel-bearing footwear device with reinforcement of composite material, whose innovative structure allows ensuring an optimal rigidity of the footwear structure, particularly in women's shoes with heel or wedge heel of appreciable height.
  • a second advantageous scope is that of obtaining a heel-bearing footbed device with reinforcement of composite material, whose innovative structure allows a significant reduction of the weight of the footbed and, consequently, of the whole shoe, as well as an optimal positioning of the retaining means of the upper and heel thanks to the particular structure of the reinforcing body.
  • a third advantageous scope is obtaining a heel-bearing footbed device with reinforcement of composite material whose innovative structure allows avoiding the above mentioned drawbacks of the footbed structures provided with metal shank, in order to avoid the inopportune activation of metal detector safety devices.
  • a more advantageous scope consists in obtaining a heel-bearing footbed device with reinforcement of composite material whose innovative structure allows a greater walking comfort, and a reduction of production costs and times of the whole footwear itself.
  • a heel-bearing footbed device (1) for footwear with reinforcement of composite material which, in the preferred embodiment described, as shown in figures 1 to 7 , includes a front portion (2) corresponding to the area of the phalanges and at least to a portion of the metatarsus area, being made in a known way and with known materials being at least partially flexible in the area wherein the front portion (2) is connected, usually and in a known way, preferably by means of adhesives, to the back portion (3) constituting the footbed portion intended for bearing the heel ( Fig. 1 ).
  • the back portion (3) of the heel-bearing footbed (1) specifically corresponds to the portion of the foot partially coinciding with the metatarsus and tarsus.
  • the back portion (3) of the heel-bearing footbed device (1) includes a reinforcing body (4) ( Fig. 3 ) made of composite material.
  • the composite material forming the reinforcing body (4) is of a known type, being indifferently of carbon fibre and/or aramide fibre, by way of example Kevlar and/or glass fibre.
  • the material for manufacturing the reinforcing body (4) corresponds to the teaching of the Italian patent application n.
  • carbon fibre composite material comprising a reinforcement made of carbon fibres which can indistinctly be of long and/or short type, with constant sizes and lengths, or made of an assembly of long and/or short fibres, with different lengths and sizes, or, indifferently, of a bundle of carbon fibres made of an assembly of one-way strands or variously twisted or woven fibres, the same carbon fibres being mixed, by means of known methods, to a polyurethane matrix whose index of hardness is equal to or higher than 70 ShoreD.
  • the use of composite materials for manufacturing the reinforcing body (4) of the back part (3) of the heel-bearing footbed (1) is particularly suitable to achieve a footbed structure having a suitable rigidity degree and an appreciably contained weight.
  • a glass fibre composite material whose reinforcement consists of 70% of glass fibres in a matrix of thermoplastic resins containing a combination of semi-crystalline polyamide and partially aromatic polyamide.
  • the shape of the reinforcing body (4) necessarily depends on the overall shape of the heel-bearing footbed (1), while the shape of the heel-bearing footbed itself (1) depends on the overall shape of the whole shoe.
  • the process for manufacturing the reinforcing body (4) is conventionally carried out by means of known execution methods, such as, by way of non-exhaustive example, by a moulding process.
  • the reinforcing body (4) has suitable slots (41 a) at least for anchoring the upper, and suitable slots (41 b) at least for anchoring the heel, which slots (41 a, 41 b) can be of different number and shape and should be placed in the areas in which the anchoring of other shoe parts is provided, like the upper, the heel or wedge heel, the leather, and/or textile laterals, and all other possible shoe accessories which may complete the footwear.
  • the slots (41 a) provided for anchoring the upper, and the slots (41 b) provided for anchoring the heel can be blind slots, being shaped as recess areas, or through slots. Describing the embodiment more in detail, ( Fig.
  • the slots (41 a) for anchoring the upper are through slots, being suitably and differently shaped, and placed near the perimeter edge of the reinforcing body (4) whose development they follow at least partially.
  • the slots (41 a) for anchoring the upper are placed in such a way as to be parallel and to mirror each other, being placed, in the example, in opposite pairs, wherein a first pair is placed at the front portion, a second pair is placed in the central area, and a third pair is placed in the back portion, coinciding with the heel positioning area of the reinforcing body (4).
  • the slots (41 b) for anchoring the heel are two, each being mirror-opposite and parallel to the other, and they are placed adjacent to the slots (41 a) for anchoring the upper placed in the back area of the reinforcing body (4), the slots (41 b) for anchoring the heel being shaped in such a way as to follow, at least partially, the development of the back area of the reinforcing body (4).
  • the reinforcing body (4) is provided with an opening (42), preferably a through opening, placed in such a way as to coincide, at least partially, with the centre of the anchoring area of the heel, and, in any case, so as to cover the area of the heel wherein the positioning of at least one anchoring screw is provided.
  • the reinforcing body (4) constitutes the rigid core of the back portion (3) of the heel-bearing footbed device (1).
  • the reinforcing body (4) is partially or completely covered by a covering shell (5) ( Fig. 7 ) preferably made of plastic, thermoplastic or thermo-hardening material, ABS in the example, having a counter-shaped coupling face.
