Definitions

  • the present invention concerns the footwear industry. More specifically, it concerns a semi-finished monoblock for cold weather footwear made with two or more materials and directly moulded to an internal insulating insole and subsequently glued or moulded to an external sole.
  • the sole is chosen according to the aesthetic and functional requirements of the user and in such a way as to produce a cold weather shoe with functional and aesthetic characteristics that are better than those currently available on the market and with the possibility for them to be moulded also with the accessories required by the relevant legislation covering the specific use for which the cold weather shoe has been configured.
  • Shoes that are used in cold climates generally include a semi-finished element, called a monoblock, the interior of which is then insulated in order to protect the foot from low temperatures.
  • the aforementioned semi-finished monoblock to the upper part of which the leg of the shoe upper is applied, or it is glued to a sole made of a different material from the insulating semi-finished element or it is directly moulded to the sole, fitting different materials within its interior in order to increase the foot's protection from the cold outside.
  • the aforementioned semi-finished monoblock of a cold weather shoe guarantees the insulation of its own interior, on the other it conditions and limits the configuration of the shoe which depends on the type of insulating material with which it has been made.
  • the direct moulding of the sole to the monoblock guarantees effective waterproofing
  • the tread sole limits the choice of the type of tread, since the tread sole is an integral part of the mould.
  • the current method employed is to use a semi-finished monoblock that is moulded in one material only, devoid of bottom or tread sole to which an insole is inserted with a special type of stitching technically known as a strobel stitch.
  • the semifinished monoblock thus obtained is subsequently glued to a tread sole and then finished off with the application on its upper part of the leg of the upper.
  • the aforementioned second type of monoblock is conditional on the single material with which it is moulded and by the choice of the insulating materials which obstruct the realisation of excellent finishes of the cold weather shoe.
  • this invention has the aim of providing a semi-finished monoblock for cold weather footwear moulded directly with the internal insole in order to make it totally waterproof and perfectly insulated, eliminating the need for the hygienic insole or fusbett and its strobel stitching, thereby simplifying the production process and reducing the cost of production of the cold weather shoe.
  • this invention has the aim of providing a semi-finished monoblock for cold weather footwear, the configuration and functionality of which no longer depend on the insulating material with which the monoblock has been moulded.
  • this invention has the aim of providing a semi-finished monoblock for cold weather footwear that can directly accommodate within its interior during the moulding phase specific technical devices such as the accident-prevention devices envisaged by the safety standards laid down for safety footwear. This allows considerable savings in their production costs.
  • this invention has the aim of providing a semi-finished monoblock for cold weather footwear that can isolate and insulate all sides of the foot, the realisation of which takes place directly during the moulding phase alone.
  • the invention that is object of the present application presents the variation of permitting the monoblock to be moulded directly with the accessories required by accident-prevention legislation for safety footwear, such as the fitting of reinforced or crush-resistant toe caps or of an internal anti-perforation insole.
  • FIG. 1 shows a side cross-section of the monoblock that is the object of the present application
  • FIG. 2 is a side view of the semi-finished monoblock detached from the external bottom and from the leg of the upper;
  • FIG. 3 is a perspective view of the finished cold weather shoe.
  • the invention that is the object of the present application is a semi-finished monoblock ( 1 ) for cold weather footwear ( 9 ) moulded with two or more materials that, depending on the use for which the said type of shoe is configured, may be equipped directly also with accessories that improve its performance and that are envisaged by the appropriate accident-prevention legislation required, for example, for safety footwear.
  • the material ( 2 ) chosen will have the characteristic of being an expanded and/or insulating type of material in order to isolate the foot from the harsh external temperatures, while for its external part materials ( 4 / a ) and ( 4 / b ) with aesthetic and technical characteristics will be chosen in order to facilitate its assembling to the tread sole ( 3 ) of the monoblock ( 1 ), for the moulding of which harder or softer materials will be employed depending on the use for which the finished product is configured, or that guarantee the specific characteristics required by the final use of the shoe ( 9 ).
  • the insulation of the semi-finished monoblock ( 1 ) is ensured by the insulating materials ( 2 ) moulded inside it that totally envelop the foot in order to guarantee the total waterproofing of its interior.
  • the semi-finished monoblock ( 1 ) of this invention also provides for the possibility of being directly equipped with the accessories required by the accident-prevention legislation for safety footwear, such as an anti-perforation insole ( 6 ) or a reinforced, crush-resistant toe cap ( 5 ).
  • the top leg of the upper ( 8 ) is fitted on the monoblock ( 1 ) with a view to obtaining the cold weather shoe ( 9 ) composed of its three main elements: the leg ( 8 ) which is the uppermost part of the shoe, the external sole ( 3 ) with its tread ( 10 ), and the semifinished monoblock ( 1 ) as described above.
