Definitions

  • the present invention refers to an helmet provided with aerating holes and to its manufacturing process.
  • the invention refers to an helmet of the type comprising a cap provided with a plurality of holes for transpiration of user's head and to the process for producing such helmet.
  • the helmets are generally realised coupling in an outer cap made of plastic material, an internal padding made of a soft material, subsequently covered with a tissue or other material for a better comfort.
  • the outer cap can be further covered by a decorative cap, made of plastic material, having printed decorations and various colourings.
  • helmets provided with holes for allowing transpiration of the user's head.
  • This kind of helmets provided with transpiration holes is used particularly by those who practice cycling, skate-boarding, roller-skating, etc.
  • the cap has a substantially hemispherical shape and the holes must be placed all over the surface of the cap according to axes substantially converging to the centre of the sphere.
  • figure 1 it is shown schematically a section of a cap 1 of a prior art helmet provided with holes.
  • the holes 10a-10e have axes 20a-20e substantially converging towards the cap's centre.
  • a first object of the present invention it is therefore to provide a helmet provided with holes having low production costs.
  • Another object of the present invention it is therefore to provide a process for manufacturing perforated helmets which permits the use of a reduced number of molds allowing however the realisation of a almost infinite range of perforated caps.
  • the helmet's cap comprises a plurality of cap portions each provided with holes and coupled together by gluing.
  • each cap portion can be cheaply obtained starting from a cheap mold in which it is possible to extract the molded object in only one direction.
  • the helmet according to the invention shows moreover better transpiration characteristics in respect to prior art and permits to obtain a better refreshment of the cap when the helmet is wore.
  • cap 1 made of foamed plastic material, for example polystyrene, provided with a plurality of radial holes 10a-10e substantially made on all its surface.
  • the holes 10a-10e have axes arranged radially as regards to the centre of the hemisphere defined by cap 1 in order to let air flowing towards the outside and thus facilitating transpiration of the user's head.
  • the helmet's cap 1 is obtained by overlapping and joining of cap portions or shells 1a-1d, each provided with a plurality of holes 10.
  • Said holes 10 are realised so that each portion of cap 1a-1d can be extracted from respective mold along only one output direction.
  • holes 10 have axes 20 substantially parallel for every cap portion 1a-1d.
  • the helmet according to the invention provides a plurality of cap portions or shells 1a-1d provided with holes 10', 10'' and coupled together by gluing.
  • the helmet according to the invention comprises a first inner cap or shell portion 1a shaped substantially hemispherical in which it are present a plurality of holes 10' realised according to axes substantially parallel each other.
  • cap portion 1a results removable along only one direction out of the mold in which it has been molded.
  • cap portion 1a from a simple and cheap mold for plastic materials.
  • the whole helmet cap is obtained by gluing on said inner shell 1a outer shells 1b-1d presenting themselves a plurality of holes 10'' realised according to axes substantially parallel to each other.
  • each of them provides a plurality of inserts 3a that couple with corresponding holes 3b.
  • said inner shell 1a has a perimetrical edge 7 flat and without aerating holes, suitable for supporting said outer shells 1b-1d.
  • Said edge 7 is moreover provided with inserts 3a and holes 3b alternately placed for centering of shells 1b-1d when these are coupled to said inner shell 1a.
  • a corresponding number of grooves, ramifying between holes 10'', are made on the surface of outer shells 1b-1d that will be coupled with inner shell 1a.
  • holes 10', 10'' provided in cap 1 for transpiration is defined a plurality of channels for the passage of air following a path that facilitates its downflow when the helmet's user advances in the direction indicated by arrow 5 in figures 2 and 3.
  • the passage of air between said channels defined by grooves 4 permits to refresh the inside of the helmet and to increase the transpiration through holes 10', 10''.
  • the shell 6 is preferably made of transparent polycarbonate and it is substantially flexible, provided with holes 10''' and with decorations.
  • Said shell 6 is applied to the cap 1 by gluing.
  • the effect resulting by applying the shell 6 on the cap 1 is substantially the same as the effect that should be obtained with a cap realised in a single part.
  • the helmet according to the invention can be realised according to the known co-molding technique that provides for simultaneously molding of the foamed material cap and the decorative shell.
  • each cap portion 1b-1d is co-molded with the corresponding portion of decorative shell.
  • the complete helmet is obtained by gluing the cap portion 1b-1d already provided with the decorative shell on the hemispheric portion 1a.
  • the cap can be obtained by gluing along adjacent edges of two cap portions each corresponding to a quarter of a sphere thus obtaining a complete hemispherical cap.
