Definitions

  • the present invention refers to a fastening system for the chin guard of an openable helmet.
  • Said helmets provide a chin guard which is pivotally attached to the side walls of the helmet so as to be able to be opened and closed according to the user's needs.
  • two fastening devices are provided in the side walls which lock the chin guard in the closed position.
  • helmets having an openable chin guard, which have only one button located in the front portion of the chin guard. Such button is connected to complicated linkages which simultaneously release the two side fastening devices.
  • An object of the present invention is to provide a fastening system for the chin guard of an openable helmet that is practical, versatile and simple to make.
  • the fastening system for the chin guard of a helmet provides two fastening devices disposed on the right and left of the helmet.
  • Each fastening device provides a slot which receives a pin positioned in the side part of the chin guard, protruding inwardly.
  • Each fastening device further provides a lever for locking the pin in the slot when the chin guard is closed.
  • the lever of one fastening device (preferably the left-hand one) is normally in a closed position because it is urged by spring means and the lever of the other fastening device (preferably the right-hand one) can be operated manually to pass from a closing position to an opening position.
  • the advantages of the device according to the invention are apparent in that it allows raising/lowering of the chin guard using only one hand, without the risk of removing both hands from the handle bar of the vehicle.
  • a helmet indicated as a whole with reference numeral 1, comprises an outer shell 2 made, for example, of ABS by injection moulding. Situated beneath the outer shell 2, in a substantially per se known manner, is an inner shell made of foamed polystyrene which is lined with a padding of foamed polyurethane and fabric intended to come into contact with the user's head.
  • a chin guard 3 is pivotally mounted on the outer shell 2, by means of pins 4 fixed to the two lateral ends of the outer shell 2, substantially level with the ears of the user who wears the helmet 1. In this manner, by exerting upward pressure on the bottom part of the chin guard 3, the chin guard 3 rises, turning around the axis of the pins 4.
  • an opening is defined to allow visibility for the user who wears the helmet 1.
  • the profile 5 of said opening is covered by a rubber seal and the opening is covered by a visor 6 of transparent material, such as injection-moulded polycarbonate, for example.
  • the visor 6 is pivotally attached to the chin guard 3 by means of two pins, disposed laterally, substantially level with the temples of the user who wears the helmet.
  • two protruding lunettes 8 are provided which face two flared parts 9 provided in the chin guard 3, so as to facilitate raising of the visor 6 by the user who can press on the protruding lunettes 8 by placing his/her fingers in the flared parts 9. In this manner, with an upward pressure exerted on the protruding lunettes 8, the visor 6 is raised, turning around the axis of its own pins.
  • FIG. 2 shows the helmet 1, seen from the right of the user who wears it, with the chin guard 3 raised, in which the fastening device 10 for the chin guard according to the invention can be seen disposed in the bottom edge of the side part of the outer shell 2.
  • the fastening device 10 comprises a mounting plate 11 fixed integrally, by means of three screws 12, to the outer shell 2.
  • the mounting plate 11 provides a slot 13 which defines a substantially rectangular corridor or passage with an entry opening 14 larger in size with respect to the rectangular corridor.
  • a seat 15 is defined in which an operating lever 16 is received.
  • the operating lever 16 has a stem 17, disposed inside the seat 15 and pivoted at the end thereof, by means of a pin 18, to the outer shell 2.
  • the stem 17 ends in a head or pushbutton 19 which protrudes outwardly from the seat 15 so as to be able to be manually operated by the user.
  • the stem 17 provides a retaining tooth 20 protruding in the direction of the slot 13.
  • the retaining tooth 20 is substantially crescent-shaped with a substantially convex front surface (the one facing towards the entry slot or opening 14) and a substantially concave rear surface.
  • the lever 16 can assume an opening position, shown in Figure 2, in which the retaining tooth 20 is contained in the seat 15 and does not protrude into the cam slot 13 and a closing position ( Figure 4) in which the retaining tooth 20 protrudes into the cam slot 13.
  • the user by pushing the head 19 of the lever 16 upward, places the lever 16 in the closing position and, by pushing the head 19 of the lever 16 downward, places it in the opening position.
  • the pin 21 As shown in Figure 2, in the right hand part of the chin guard 3 there is provided a pin 21 which protrudes toward the inside of the chin guard 3, so that when the chin guard 3 is lowered, the pin 21 engages in the corridor 13. As shown in Figures 5 and 6, the pin 21 has a substantially T-shaped longitudinal section, in which the part of the pin 21 with a larger diameter has a slightly smaller diameter with respect to the width of the entry opening 14 and the part of the pin 21 with a smaller diameter has a slightly smaller diameter with respect to the width of the slot 13.
  • Figure 3 shows the helmet 1, seen from the left of the user who wears it, with the chin guard 3 raised, in which like or corresponding elements are designated with the same reference numerals as those previously described and are not further described.
  • the shape of the fastening device 110 disposed on the left of the helmet is perfectly symmetrical with that of the fastening device 10 disposed on the right of the helmet.
  • Figures 4 and 7 show the left and right hand fastening devices 10, 110 when the chin guard 3 is lowered.
  • the fixing pins 21 of the chin guard disposed to the left and the right are both at the end of the respective corridors 13.
  • the left and right hand operating levers also are in the closing position with the respective retaining teeth 20 retaining the respective pins 21.
  • the left hand operating lever 16 through the action of the spring 30, automatically goes into the closing position, ensuring safety locking of the chin guard, whereas the right hand operating lever 16 must be raised by the user to position itself in the closing position.
  • the user To raise the chin guard, the user must therefore perform the following operations. Firstly with the right hand he must lower the right hand operating lever 16 to bring it into the opening position. Then with the left hand the user lowers the left hand operating lever 16 and at the same time raises the chin guard. This operation can be performed with one hand, for example by pressing the head 19 of the left hand lever with the thumb of the left hand and at the same time raising the chin guard with the index finger of the left hand.
  • the position of the fastening devices 10, 110 of the chin guard can be inverted, for example for helmets intended for users who prefer to work on the helmet with the right hand.
