Definitions

  • the visor must be able to be lifted and lowered extremely quickly, using only one hand, and often, indeed, substantially necessarily, while wearing motorcycle gloves.
  • the opening and closing of the visor must also be such as to ensure a perfect seal between the visor and the shell of the helmet, in order to prevent unwanted air drafts, which produce both annoying noises and discomfort for the eyes of the user.
  • the opening and closing of the visor are provided by acting on a protruding portion of the visor, with the presence of metal springs that allow to keep the visor in the closed position, and with complex assemblies with various metal and plastic materials, and numerous elements involved in the opening/closing mechanism.
  • the aim of the present invention is to provide a device for opening/closing the visor of a helmet that allows to open and close the visor in the absence of metal springs.
  • an object of the present invention is to provide a device for opening/closing the visor of a helmet that has a reduced number of component parts.
  • Not least object of the present invention is to provide a device for opening/closing the visor of a helmet that is highly reliable, relatively easy to provide, and at competitive costs.
  • a device for opening/closing the visor of a helmet characterized in that it comprises a base element, which is configured to be associated stably with the shell of a helmet and is adapted to form a receptacle, and a male element, which is adapted to be associated stably with the visor of the helmet and is adapted to form an elastically flexible tooth which is adapted to be engaged in said receptacle of said base element, said male element being provided with a tab which protrudes from said base element when said male element is engaged in said base element, for the lifting/lowering of said visor.
  • the device for opening/closing the visor of a helmet is generally designated by the reference numeral 1 and comprises a base element 2 adapted to be rendered integral with a shell 3 of a helmet and provided so as to form a female receptacle for a male element 5 adapted to be rendered integral with the visor 4 of the helmet.
  • the male element 5 comprises a tooth which is made of plastic material and therefore inherently flexible and is substantially U-shaped, with a portion of the rounded region of the U-shape that is flattened so as to adhere to the female base element 2.
  • the male element 5 is therefore shaped complementarily to the base element 2.
  • the receptacle of the base element 2 within which the male element 5 engages is conveniently provided with retention means 8 adapted to form an undercut that allows the locking of the male element 5 when it engages in the receptacle of the base element 2.
  • the male element 5 is provided with a tab 6 which is adapted to protrude from the female base element 2 so that it can be easily gripped by the user with the hands, even when wearing gloves.
  • the male element 5 is provided with a pair of retention teeth 9 arranged laterally to the tab 6.
  • the retention teeth 9 are adapted to engage under the retention means (undercuts) 8 of the receptacle of the base element 2 when the male element 5 enters the base element 2.
  • the male element 5 is configured to be integral with the visor 4 of the helmet, by means of a pin 7, while the female base element 2 is adapted to be rendered integral with the shell 3 of the helmet.
  • the U-shape of the male element 5, which is essentially configured as a tooth that protrudes downward from the visor 4, and is adapted to engage in the receptacle formed by the female element 2, allows the male element 5 to be elastic, so as to allow its insertion by forcing within the female base element 2, with the retention teeth 9 moving beyond the retention means 8 and locking below them, and its disengagement, acting against the tab 6, so that the walls of the male element move mutually closer, as a result of elastic deformation of the male element, so that it can be allowed to exit from the receptacle of the female base element 2, disengaging the retention teeth 9 from the retention means 8 of the receptacle of the base element 2.
  • the metal springs present in devices of the known type are replaced in the present invention by a tooth made of plastic material constituted by the male element 5, which can flex by virtue of its shape once the user acts on the protruding tab 6, which is integral with the male element 5.
  • the engagement and disengagement of the visor 4 with the shell 3 occur in an extremely simplified manner, without complex assemblies of numerous parts, without the presence of metal springs, and above all with a durability over time that does not depend on the elastic capacity of the springs but is simply entrusted to the flexibility of the male element 5, which is preferably made of plastic material and does not change its characteristics substantially over time.
  • the device according to the present invention is arranged centrally in axial alignment with the centerline of the helmet.
  • the device according to the present invention is arranged laterally.
  • the device according to the present invention fully achieves the intended aim and objects, since it allows to open/close the visor of the helmet without the use of metal springs and most of all with a device constituted by an extremely reduced number of component parts.
  • the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and the state of the art.
