Definitions

  • the present invention relates to a helmet for motorcycling, and more in particular to a helmet for motorcycling of modular type that can be homologated and can be used both in full face configuration and in jet configuration.
  • a particular type of helmet for motorcycling consists of modular helmets having the characteristic of being able to be used as full face helmets or as jet helmets and that are homologated for both configurations.
  • modular helmets are equipped with a chin guard that is not produced in once piece with the shell, but is a separate piece that can rotate with respect to the shell, moving upward and releasing the mandibular region of the user, in this way transforming the helmet from full face to jet, and vice versa.
  • Modular helmets being reversibly transformable from full face to jet and vice versa, offer a good compromise between safety and comfort, but are considerably heavier and bulkier than jet and full face helmets and, above all when riding with the chin guard open, noisy and uncomfortable, due to the significant sail effect exerted by the chin guard in open position.
  • the chin guard is located in correspondence of the frontal or upper region of the user's skull, offering noteworthy aerodynamic resistance during movement. Consequently, a pressure is generated on the helmet and accordingly on the user, who is obliged to tense the neck muscles to oppose the effect of this pressure, without forgetting the decidedly annoying noise generated by air turbulence around the open chin guard.
  • helmets have been proposed in which, once opened, the chin guard is brought in correspondence of the rear part of the shell.
  • the arc of rotation of the chin guard during switching from the closed position to the open position, and vice versa must be relatively wide. Accordingly, the chin guard, in the open position, projects even substantially from the rear part of the shell. Therefore, the problems of noise generated by air turbulence are always present, while the problems of air pressure on the chin guard, and consequently on the helmet, remain, albeit to a lesser extent with respect to the preceding case.
  • the patent EP 1 806 986 B1 by Shark SA proposes a helmet for motorcycling which attempts to find a solution to these problems through an opening mechanism of the chin guard that includes:
  • Patent Application WO 2006/128833 A1 discloses another example of a modular helmet with a movable chin guard and visor. It is therefore evident that the modular helmets for motorcycling of known type have a series of problems that make their use not always ideal.
  • the main aim of the present invention is to provide a helmet for motorcycling of modular type that solves the drawbacks and problems described above.
  • an object of the present invention is to provide a helmet for motorcycling of modular type, which reduces the negative aerodynamic effects when travelling with the chin guard open.
  • Another aim of the present invention is to provide a helmet of modular type for motorcycling in which turbulence and noise are reduced.
  • Another aim of the present invention is to provide a helmet of modular type for motorcycling, in which interference between visor and chin guard are prevented during the opening and closing movement of this latter.
  • Another object of the present invention is to provide a helmet of modular type for motorcycling that is provided with relatively simple kinematic mechanisms for opening and closing the chin guard and the visor.
  • Another object of the present invention is to provide a helmet of modular type for motorcycling in which switching from full face to jet configuration can be easily and rapidly implemented by the user.
  • One more object of the present invention is to provide a helmet of modular type for motorcycling that is safe and in which locking of the chin guard in positions that would to obstruct or reduce the user's visibility is prevented.
  • Yet another object of the present invention is to provide a helmet of modular type for motorcycling which is highly reliable and easy to produce at competitive costs.
  • a helmet for motorcycling comprising a shell, at least one visor mounted on said shell and movable in rotation with respect to said shell from a closed position to an open position and vice versa, and a chin guard connected to said shell and movable with respect to it from a closed position to an open position in correspondence of the rear part of said shell, characterized in that it comprises means for opening and closing of said visor and said chin guard comprising:- automatic opening means for the automatic switching of said visor from said closed position to said open position;
  • a helmet of modular type for motorcycling thus conceived has a plurality of features and properties that enable the drawbacks and problems described above to be overcome.
  • the guide means of the chin guard which confer a circular trajectory on it during a first phase of the opening movement and a trajectory in rotation and translation with respect to the shell during a second phase of the opening movement make it possible to obtain a helmet in jet configuration in which the chin guard is closely adjacent to the rear part of the shell eliminating, or at least greatly limiting, the negative aerodynamic effects in terms of air pressure and noise generated by turbulence.
  • the locking/unlocking mechanism of the visor and of the chin guard is relatively simple and easy to use by the user.
  • the fact that the second kinematic mechanism for unlocking and opening of the visor allows automatic switching from the closed position to the open position of the visor when the chin guard is closed ensures absolute safety, as all interference between visor and chin guard during said operation is avoided.
  • said first kinematic mechanism for unlocking and opening of said visor and of said chin guard comprises at least one button positioned on said chin guard and operatively connected to said visor for unlocking of said visor from said closed position. Following actuation of this button, the visor is brought automatically to the open position due to the presence of the automatic opening means of said visor and use by the user is greatly simplified with respect to helmets of known type in which the whole opening operation is normally performed manually.
  • buttons are understood to mean any device, for example a key, a lever, a knob, or similar devices, that can be actuated manually by the user and that is able to transfer the actuation command to the kinematic mechanisms and operating devices connected to it.
  • the automatic opening means of the visor preferably comprise elastic means, for example spring means, which are operatively coupled to the visor and to the shell and determine the movement of the visor from the closed position to the open position of the visor when the visor is not retained in closed position by the visor locking means. Switching of the visor from the open position to the closed position is instead performed manually by the user, who acts manually on the visor and, overcoming the resistance of the elastic means, brings the visor into the closed position where it is retained by the locking means.
  • elastic means for example spring means
  • the elastic force exerted by the elastic means can advantageously be chosen as a function of the required opening speed of the visor, or of the force required to overcome the resistance of the elastic means to return the visor to the closed position.
  • damping means can be provided to slow the visor during the final phase of opening and reduce the impact force that is generated when movement of the visor stops.
  • said first kinematic mechanism for unlocking and opening of said visor and said chin guard comprises a first button positioned on the chin guard and operatively connected to the visor for unlocking of said visor from its closed position.
  • the first kinematic mechanism for unlocking comprises a first button and a second button.
  • said first button is operatively connected to the visor for unlocking of said visor from said closed position
  • the second button also positioned on said chin guard, is operatively connected to said first button and is actuatable only upon actuation of said first button .
  • actuation of the first button allows unlocking and consequently automatic opening of the visor as described previously, while the second button allows unlocking and subsequent opening of the chin guard; the second button cannot be actuated unless the first button is actuated first, thus preventing situations of potential interference between visor and chin guard during the opening of this latter.
  • said locking means of said visor in said closed position comprise first visor locking means for maintaining said visor in said closed position when the chin guard is in closed position and second visor locking means for maintaining said visor in closed position when the chin guard is in open position.
  • said second locking means of said visor comprise first engagement means positioned on the guide means of said visor engageable with and disengageable from second engagement means positioned on the guide means of said chin guard.
  • said first locking means of said visor comprise third engagement means that are positioned on said chin guard and are operatively connected to said first kinematic mechanism for unlocking and opening: said third engagement means are engageable with and disengageable from fourth engagement means positioned on said visor.
  • the visor in the full face helmet configuration is maintained closed by the third engagement means positioned on the chin guard that engage the fourth engagement means positioned on the visor; acting on the first kinematic mechanism for unlocking and opening of the visor and of the chin guard, the third engagement means disengage from fourth engagement means thereby allowing the visor to be brought automatically in the open position.
  • the guide means of said chin guard comprise a first guide plate of the chin guard rigidly coupled to said shell, a second guide plate rigidly coupled to said chin guard and coupling means between said first guide plate and said second guide plate that guide said second guide plate along a circular trajectory during a first phase of the movement of said chin guard from said closed position to said open position and along a trajectory in rotation and translation during a second phase of movement of said chin guard from said closed position to said open position.
  • the coupling means between the first guide plate and the second guide plate form the interface between chin guard and shell, guiding the movement of the chin guard during switching from the closed position to the open position, and vice versa.
  • said coupling means between said first guide plate and said second guide plate comprise a third guide plate pivoted on the first guide plate; the second guide plate is advantageously slidingly coupled to said third guide plate, follows its movement of rotation with respect to the shell and is free to slide linearly with respect to it.
  • the third guide plate is free to rotate with respect to the shell and the second guide plate, rigidly coupled to the chin guard, follows it in rotation during a first phase of the opening movement of the chin guard; in a second phase of the opening movement of the chin guard, the second guide plate, together with the chin guard rigidly coupled to it, translates linearly with respect to the third guide plate, thus producing the trajectory in rotation and translation of the chin guard described previously.
  • said guide means of said visor comprise a visor rotation lever pivoted on a first rotation pin and free to rotate with respect to said shell;
  • the automatic opening means for the automatic switching of said visor from said closed position to said open position advantageously comprise elastic means, for example spring means, which are operatively associated with said rotation lever.
  • said first guide plate is interposed between said visor rotation lever and said third guide plate; in this case the second locking means of said visor can advantageously comprise first engagement means positioned on said visor rotation lever and engageable with/disengageable from second engagement means positioned on said first guide plate.
  • the engagement means on the visor rotation lever and on one of the guide plates of the chin guard opening of the visor takes place automatically following the movement of the chin guard from the open position to the closed position.
  • a helmet of modular type for motorcycling according to the present invention, indicated in the various figures with the reference numeral 1, comprises, in its most general embodiment, a shell 10 adapted to surround and protect the upper, rear and lateral parts of the skull of a user.
  • the helmet 1 also comprises at least one visor 11 mounted on the shell 10 in correspondence of its front part and movable from a closed position to an open position, and vice versa, through a rotation of the visor 11 about a fixed centre of rotation 61 rigidly coupled to the shell 10.
  • the helmet 1 according to the present invention is of modular type and therefore comprises a chin guard 12 connected to said shell 10 and movable with respect to it from a closed position (helmet in full face configuration) to an open position (helmet in jet configuration).
  • a first specific characteristic of the helmet 1 according to the present invention is given by the fact that, in the open position, the chin guard 12 is positioned in correspondence of the rear part 101 of said shell 10, thus avoiding the problems of aerodynamic resistance, turbulence and noise of modular helmets of known type.
  • front refers to the conditions of normal use of the helmet when worn by the user.
  • the modular helmet 1 according to the present invention is mainly characterized for the particular structure, positioning and operation of the means for opening and closing of said visor 11 and said chin guard 12.
  • the means for opening and closing of the visor 11 and of the chin guard 12 in fact comprise automatic opening means 2 for the automatic switching of the visor 11 from the closed position to the open position.
  • Said automatic opening means 2 can, for example, consist of elastic means, for example spring means, operatively coupled to the visor 11 and which determine its automatic switching from the closed position to the open position.
  • the term "automatic” is understood to mean that switching of the visor 11 from the closed position to the open position is not performed manually by the user but takes place autonomously once the visor 11 is unlocked, as better described below.
  • the means for opening and closing of the visor also comprise locking means 3 of said visor 11 in said closed position.
  • Kinematic mechanisms for unlocking and opening act on said locking means 3, releasing the visor 11 and allowing it to open automatically due to the action of the automatic opening means 2.
  • the means for opening and closing of the visor 11 and of the chin guard 12 in fact also comprise a first kinematic mechanism 4 for unlocking and opening of said visor 11 and of said chin guard 12 which allows release of the visor and of the chin guard for the switching from their closed position to their open position.
  • the chin guard 12 is then guided in its movement by guide means 5 of said chin guard 12 which confer a circular trajectory with respect to the said shell 10 during a first phase of the movement of said chin guard 12 from the closed position to the open position and a trajectory in rotation and translation with respect to the shell 10 during a second phase of the movement of said chin guard 12 from said closed position to said open position.
  • the visor 11 is guided in its movement, which takes place substantially along a circular trajectory, by suitable guide means 6.
  • the means for opening and closing of the visor 11 and of the chin guard 12 also comprise a second kinematic mechanism 7 for unlocking and opening of said visor 11 that determines the automatic switching from said closed position to said open position of said visor 11 when said chin guard 12 is brought from its open position to its closed position.
  • the modular helmet 1 in full face configuration and in conditions of use, has the visor 11 and the chin guard 12 closed. In these conditions the visor 11 is retained in the closed position by the locking means 3, which prevent it from opening.
  • said first kinematic mechanism 4 for unlocking and opening of said visor 11 and of said chin guard 12 preferably comprises at least one button 41 positioned on the chin guard 12 and operatively connected to said visor 11 to unlock this latter from said closed position.
  • pressing the button 41 in the direction of the arrow 410 releases the visor 11, which is free to pivot in the direction of the arrow 110 about the pivot pin 61, for example through the action of a spring (not shown in the figure) connected to it, thus moving to its open position.
  • a spring not shown in the figure
  • the subsequent step consists in unlocking and in the start of the movement of the chin guard 12, acting on the first kinematic mechanism 4 for unlocking and opening.
  • said first kinematic mechanism 4 for unlocking and opening of said visor 11 and of said chin guard 12 preferably comprises, as well as a first button 41 positioned on the chin guard 12 and operatively connected to the visor 11 for unlocking this latter, also a second button 42, also positioned on the chin guard 12, which is operatively connected to said first button 41 and actuatable only upon actuation of said first button 41.
  • buttons 41 and 42 are easily actuatable using only one hand, for example acting on the button 42 with the thumb and on the button 41 with the index finger (or in any case with one of the other fingers opposite the thumb).
  • the trajectory of said chin guard is circular (arrows 120 and 121) about the fixed centre of rotation 500.
  • This first phase of movement ends when the chin guard 12 is located at least in substantial correspondence of the top of the shell 10 or, preferably, has moved beyond the top of the shell 10.
  • a second phase of the opening movement of the chin guard 12 starts, during which said chin guard 12 is guided along a trajectory in rotation and translation with respect to said shell 10.
  • the chin guard 12 continues to rotate about the fixed centre of rotation 500 in the direction of the arrow 122, but simultaneously translates with respect to it along the axis 124 in the direction of the arrow 123.
  • the chin guard 12 moves towards the rear part 101 of the shell 10 which ends in the position of Fig. 6 , where the chin guard 12 is completely open and rotates backwards in a position closely adjacent to the rear part 101 of the shell 10.
  • the modular helmet 1 according to the present invention is brought into jet configuration and into the conditions of use, with the visor 11 closed and the chin guard 12 open. In these conditions the visor 11 is retained in the closed position by the locking means 3 which prevent it from opening.
  • said locking means 3 of the visor 11 in the closed position preferably comprise first locking means 31 of said visor 11 for maintaining said visor 11 in said closed position when the chin guard 12 is in closed position and second locking means 32 of said visor 11 for maintaining the visor 11 in the closed position when said chin guard 12 is in open position.
  • said first locking means 31 of the visor 11 preferably comprise third engagement means 313 (for example a detent) positioned on said chin guard 12 and operatively connected to said first kinematic mechanism 4 for unlocking and opening, for example to the button 41.
  • Said third engagement means 313 are engageable with and disengageable from fourth engagement means 314 (for example a seat for said detent) which are positioned on said visor 11.
  • the third engagement means 313 for example a detent
  • fourth engagement means 314 for example a seat for said detent
  • said second locking means 32 of said visor 11 preferably comprise first engagement means (described more in detail below) positioned on the guide means of said visor 11 and which are engageable with and disengageable from second engagement means (described in more detail below) positioned on the guide means 5 of said chin guard 12. In this way, the visor 11 can be opened automatically when closing of the chin guard 12 starts.
  • a second kinematic mechanism 7 for unlocking and opening of said visor 11 determines the automatic switching from the closed position to the open position of said visor 11 when said chin guard 12 is brought from its open position to its closed position, preventing these situations of potential risk.
  • the chin guard 12 when as a result of manual action by the user, the chin guard 12 starts to move, it starts to rotate in the direction of the arrow 125 and to translate in the direction of the arrow 126, in the opposite way to the second phase of the opening movement (see Fig. 5 ).
  • This initial movement triggers the kinematic mechanism 7 for unlocking and opening of the visor 11 (an example of which will be described in detail below) which releases the visor 11 allowing it to automatically open in the direction of the arrow 110 as a result of the automatic opening means 2.
  • the trajectory of the chin guard 12 from the open position to the closed position is therefore free from obstructions and said chin guard 12 can therefore reach its closed position (corresponding to that of Fig. 2 ) without there being interference between it and the visor 11.
  • said guide means 5 of the chin guard 12 preferably comprise a first guide plate 51 of the chin guard 12 which is rigidly coupled to said shell 10.
  • a plate 8 for coupling to the shell 10 that houses and allows fixing of the various components of the mechanism. Therefore, in this case said first guide plate 51 is coupled to said shell 10 through a fixing hole 81 provided in said plate 8 for coupling to the shell.
  • the guide means 5 of the chin guard 12 also comprise a second guide plate 52 which is rigidly coupled to said chin guard 12 and coupling means 50 between said first guide plate 51 and said second guide plate 52.
  • Said coupling means 50 guide said second guide plate 52 (and consequently the chin guard 12 rigidly coupled to it) along a circular trajectory about a fixed centre of rotation 500 present on said first plate 51, during a first phase of the movement of said chin guard 12 from said closed position to said open position, and along a trajectory in rotation and translation with respect to said fixed rotation centre 500 during a second phase of the movement of said chin guard 12 from said closed position to said open position.

  • said third guide plate 53 has sliding seats 532 and 533 adapted to house corresponding lateral ribs 522 (visible only on one side) of the second guide plate 52 that are free to slide in said sliding seat.
  • the second plate 52 follows said third guide plate 53 during its movement of rotation with respect to said shell 10 (about the fixed centre of rotation 500) and is free to slide linearly with respect to it.
  • the second guide plate 52 also has a groove 521 for operatively coupling with the fixed centre of rotation 500, for example through a bushing 520, and is therefore free to rotate and translate with respect to said fixed centre of rotation 500. Moreover, the second guide plate 52 has a lateral boss for coupling to the first guide plate 51, in particular to its circular guiding edge 501 and to its groove 502.
  • the first guide plate 51 is always rigidly coupled to the shell 10, while the second guide plate 52 is always rigidly coupled to the chin guard 12.
  • the second 52 and the third 53 guide plate rotate together about the fixed centre of rotation 500 (more in particular about the bushing 520); in fact, in this situation the second plate 52 cannot translate with respect to the third plate 53 as it is retained by the lateral boss 525 that slides along the circular guiding edge 501 of the first plate 51.
  • the lateral boss of the second guide plate 52 Upon reaching the position of Fig. 12 , the lateral boss of the second guide plate 52 is in correspondence of the start of the groove 502. In this situation, the second guide plate 52 is free to slide with respect to the third plate 53 and starts to translate along the axis 124 ( Fig. 13 ), with sliding of the lateral boss of the second guide plate 52 in the groove 502 of the first plate 51, and of the bushing 520 in the groove 521 of the second plate 52. Consequently, also the chin guard 12, which is rigidly coupled to the second plate 52, translates with respect to the shell 10, moving towards its rear part 101.
  • the guide means 6 of said visor 11 comprise a visor rotation lever 60 which is pivoted and free to rotate with respect to said shell 10 on a first pivot pin 61 for example through a hole 601 provided in the body of said lever 60.
  • the centre of rotation of the visor rotation lever 60 is conveniently offset with respect to the centre of rotation 500 of the chin guard 12.
  • Said lever 60 therefore preferably has an opening 602 to allow it to move with respect to the centre of rotation 500 of the chin guard 12.
  • the visor rotation lever 60 also has a pin 603 that can be used as guide pin of the lever 60 and/or as fixing point of elastic means, for example spring means (not shown in the figure), for the automatic opening of said visor 11.
  • the fixing point of the automatic opening means 2 for the automatic switching of said visor 11 from said closed position to said open position can however be varied as a function of requirements and of the type of spring used.
  • the first guide plate 51 is interposed between said visor rotation lever 60 and said third guide plate 53.
  • the second locking means 32 of the visor 11 comprise first engagement means 321 that are positioned on said visor rotation lever 60 and engageable with/disengageable from second engagement means 322 positioned on said first guide plate 51.

  • the lever 60 rotates to the right and the detent 322 slides on the surface of the lever 60 until it is in correspondence of the opening 321.
  • the detent 322 is forced to enter the opening 321 as a result of the pressure exerted by the surface 534 of the third guide plate 53, maintaining the visor 11 locked in closed position.
  • Unlocking of the visor 11 through the second unlocking kinematic mechanism 7 occurs automatically when starting to open the chin guard 12.
  • this opening causes a rotation of the third guide plate 53 to the right; consequently, the elastic detent 322 is not pressed towards the lever 60 by the surface 534 of the third guide plate 53 and is free to move away from it, disengaging from the opening 321.
  • the lever 60 is no longer retained and can rotate freely to the left, for example as a result of spring means, determining the automatic opening of the visor 11.
  • opening of the visor 11 is totally automatic, given that its movement does not require the constant manual action by the user but is triggered automatically by the closing movement of the chin guard.
  • the modular helmet according to the present invention due to the particular trajectory followed by the chin guard during its opening/closing, prevents the problems of resistance to air and of noise typical of helmets of known type.
  • the full face configuration it is like a normal full face helmet, while in jet configuration the chin guard is closely adjacent to the rear part of the shell, all with a mechanism that is relatively easy to produce and undoubtedly simple to use.
  • the means for the automatic unlocking and opening of the visor can in fact be used immediately and simply by the user.
  • the automatic opening of the visor when passing from jet configuration to full face configuration prevents any interference between visor and chin guard during the closing of this latter, thus eliminating all risk of obstructing or limiting the user's visibility as a result of the chin guard stopping in intermediate position.
