Definitions

  • the present invention relates to a protective helmet with a partializable visor.
  • the present invention relates to a protective helmet of the so-called integral type, utilized especially by motorcycle drivers, and intended for the protection of the head in case of impacts and accidents.
  • protective helmets are widely used, that envelope the head in a more or less complete manner.
  • a diffuse type of protective helmets utilized also in the sport-and athletic field, consists of a protective bubble from plastic material that covers the whole head, including the front part of the face.
  • This type of helmets called integral helmets or helmets with chin protector, ensure a complete protection of the head, also against insects or dust that can hit the face of the driver. While this protection is complete, the integral helmets have some drawbacks, related especially to the discomfort caused users by poor aeration.
  • the integral helmets of the known art have been provided with a movable visor, i.e. a shaped transparent element placed in the front zone, which, besides providing an adequate visibility to the vehicle driver, can be lifted with respect to the structure of the helmet with which it is associated.
  • the lifting of said visor determines only the creation of a more or less wide slit starting from its lower edge.
  • the opposite upper edge of the visor remains systematically in touch with the shaped surface of the helmet, which, among other things, limits its lifting or upward travel.
  • such lifting of the visor does not allow to create an adequate air re-circulation, with the consequence that the user is almost always obliged to drive in uncomfortable conditions.
  • a further drawback which is found in integral helmets concerns the difficulty of handling the opening and closing of the visor.
  • this operation requires in most cases the locking and unlocking of said visor by means of eccentric levers, located externally with respect to the lateral-rear zone of the helmet. It is, in substance, an operation that cannot be performed at once and that can be the cause of distraction during the driving and lead to severe consequences.
  • Object of the present invention is to obviate the above drawbacks.
  • object of the present invention is to realize a protective helmet whose visor can be moved in such a way as to allow the adequate re-circulation of air in the inside of the helmet worn by the user.
  • a further object of the invention is to realize a protective helmet as defined above, wherein said movement of the visor is obtained, both upwards and downwards, with a simple movement, without having recourse to encumbering means or locking and unlocking levers, and therefore without distraction danger for the user.
  • a not last object of the invention is to realize a protective helmets that has not in its inside levers or means for moving the visor, i.e. elements that, being exposed, can be damaged and that create, besides, anti-esthetic effects.
  • a further object of the invention is to provide users with a protective helmet having a partializable visor, suitable to ensure a high level of resistance and reliability in the time, and also such as to be easily and economically realizable.
  • the protective helmet with partializable visor which helmet comprises a bubble or cap from plastic material, a sector or under-plate fixed to the opposite sides of the bubble in the rear zone, a visor articulated on said under-plate through opposed projecting collars formed along the internal front of said visor, each of said under-plate comprising:
  • the protective helmet of the present invention whose partial profile is indicated by the broken lines 10, has on the opposed sides, in the rear zone, sectors or under-plates 12, provided with a plurality of shaped seats for the connection of the visor, indicated by 14 and made from polycarbonate or other suitable materials.
  • Each of sectors or under-plate 12 basically comprises a through-opening 16 having an ovoid shape, obtained in the rear part, and a shaped through-slot 18 that develops in a tendentially vertical direction and forms the sliding and stabilization seat in given points of a cylindrical pawl 20, integral with the internal front of visor 14. Additional superposed openings 22, 24, separated by a bridge 26, form the seat for a hook-shaped lever 28, which will be described later on.
  • a cursor 30 is housed, which is provided with a through-hole 32; cursor 30, on the front facing the shaped slot 18, is provided with at least a seat 34 that houses elastic means, for instance two helicoid springs 35. The opposite end of said spring encounters one of the shoulders obtained along sector 12 about the through-opening 16.
  • a projecting collar 36 abuts in hole 32 of cursor 30, said collar being integral with the internal front of visor 14; said collar 36, obtained on both sides of visor 14, constitutes the traditional rotation pin, to cause the same to lift and lowe with respect to helmet 10.
  • the first stabilization point, indicated by 38 in Figure 2 is obtained at the lower end of the shaped slot 18; Figure 1 shows the condition wherein pawl 20 is placed when it abuts in said first stabilization seat or point 38.
  • the second stabilization point, adjoining the first one, is indicated by 40; in its inside pawl 20 is positioned during the partialization step of visor 14, as will be specified later on with reference to the working.
  • the third stabilization point is formed at about half-way of the longitudinal development of the shaped through-slot 18, and consists of a cavity having a substantially semicircular profile obtained along a side of said slot.
  • two holes 44 for housing conventional screws suitable to fix the sector or under plate 12 to the bubble of helmet 10.
  • openings 22, 24 are realized wherein said hook like lever 18 is located; said openings 22, 24 are obtained on at least one of the opposite sectors or under plate 12. Opening 24 is formed in the upper part and adjoins the extreme lower zone of slot 18, before the same; bridge 26, obtained integrally with said under-plate, separate the upper opening 24 from the lower one 22, of greater width.
  • Lever 28, preferably made from plastic material, comprises a branch 46 that is located in said openings 22, 24 under bridge 26.
  • Lever 28 is perforated in correspondence of the lower end of branch 46, for the insertion of a pin 50 that forms the rotation fulcrum; said pin engages with the under-plate 12.
  • the upper end of branch 46 of said lever has, in the direction of slot 18, a cavity 52 having a semicircular profile suitable to house pawl 20, when visor 14 is in partialization condition.
  • branch 46 of lever 28 is bent towards the outside with a substantially U-shaped profile, forming a shoulder 28'; the upper end of the latter is bent towards the inside to a limited extent and forms, as indicated in detail in Figure 5, a lip 54 facing branch 46.
  • lever 28 must protrude externally with respect to visor 14, and for this purpose, the latter is provided with a notch or lowering 56 obtained along its lower edge.
  • Figure 1 shows schematically the condition of closing or total lowering of visor 14; pawl 20 abuts in the shaped through-cavity 18 in correspondence of the first stabilization point 38, obtained at the lower end of said cavity.
  • the cord-shaped extension 60 that protrudes from the external front of visor 14 strikes lip 54 of lever 28, causing a backwards tilting of the same; the upper end of branch 46 of lever 28 is therefore led to occupy cavity 18 in correspondence of the first stabilization point 38 left free from pawl 20.
  • pawl 20 is therefore in a more advanced position with respect to the original position of total closing of visor 14, as shown in Figure 3.
  • visor 14 is therefore obliged to translate in the direction of the front side, moving away along the whole perimeter from the bubble or cap of helmet 10.
  • This causes a partialization, i.e., the creation of a slit between the visor and the helmet, both in the lower and the upper parts, with the ensuing possibility of a continuos re-circulation of the air-flow.
  • the visor can be easily positioned in such a way as not to create, with respect to the body of the helmet, slits for the passage of air both along the lower edge and the upper edge, This double opening allows an adequate air circulation, which is a basic condition for the comfort of the user.
  • the movement of the visor is obtained in a simple and direct manner, with fixed sequences that can be made with one only hand, to the advantage of the safety of the driver.
