A method of managing said helmet is also described.

Description

The present disclosure relates in general to a protective helmet. In particular, the present disclosure relates to a protective helmet and also relates to a method of managing a protective helmet.
It is known to use in protective helmets a screen for protecting the front zone of a user's head. For example, the screen may be a visor able to protect a user's face, for example in the case where the user is driving/riding a vehicle, especially a two-wheeled vehicle.
The visor in fact ensures protection against impacts or air flows which may arise during driving/riding, while at the same time allowing the user to maintain the visibility necessary for driving/riding the vehicle.
Generally, the visor may be lowered or raised by the user depending on the needs and some helmets according to the prior art have fastening systems for fixing the visor in the raised portion or in the lowered position.
The known fastening or engaging system for engaging the cap with the screen of the helmet comprises a first functional element, a movement seat and a second functional element, which slides in the movement seat, against the action of a spring. The first functional element is usually an end-of-travel stop which houses the spring which opposes the movement of the second functional element.
The second functional element is configured to be able to slide in said movement seat so as to assume a distancing position with respect to the first functional element and an approaching position with respect to the first functional element, wherein, in said distancing position, said second functional element is situated further away from said first functional element than in said approaching position. The distancing position corresponds to a position in which the second functional element may protrude like a tooth and may engage with a functional counter-element, for example a seat, in order to obtain said engagement.
In an approaching position, the second functional element is momentarily pressed against the spring, so that the latter assumes a condition for storing energy, which is released when the pressure on the second functional element is released.
The present disclosure is based on the recognition by the inventor of the present disclosure that the known engagement system is subject to wear, in particular of the spring, or a loss of efficiency of the spring, or wear of the end-of-travel seat where the spring is situated, which wear may affect the efficiency of the engagement between the first functional element and the functional counter-element.
As a result, when engagement is no longer performed efficiently, sudden disengagement of the visor and/or of the chin guard may occur, to the detriment of the comfort and also the safety of the user.
Wear of the parts may also result in problems of operation and/or jamming, with the result that the visor remains stuck in a given position.
These problems, in addition to a poor level of comfort for the user, may also result in a safety risk in the case where the user is forced move the visor when it is locked in a given position owing to malfunctioning of the locking mechanism.
The starting point of the present disclosure is therefore the technical problem of providing a protective helmet which is able to satisfy all the aforementioned requirements with reference to the prior art and/or achieve further advantages.
This is obtained by means of a helmet and a method according to the respective independent claims. Secondary characteristics of the subject of the present disclosure are defined in the corresponding dependent claims.
In particular, the present disclosure proposes a helmet comprising a first component of the helmet, a second component of the helmet and an engagement system for engaging the first component of the helmet together with the second component of the helmet, said engagement system comprising a first functional element, a movement seat and a second functional element, wherein the second functional element is configured to be able to slide in said movement seat in such a way as to assume a distancing position with respect to the first functional element and an approaching position with respect to the first functional element, wherein in said distancing position said second functional element is situated further away from said first functional element than in said approaching position.
According to the present disclosure, the first functional element comprises or is a first magnet and said second functional element comprises or is a second magnet configured to exert a magnetic force which repels said first magnet in such a way as to keep normally said second functional element in said distancing position distanced from said first functional element. Depending on the system for engagement between the first component and the second component, said distancing position corresponds to a condition of engagement of the first component of the helmet with the second component of the helmet, or said distancing position corresponds to a condition of engagement of one of the first component of the helmet and the second component of the helmet with the second functional element. It is quite possible, however, to consider as equivalent or included within the scope of protection of the independent claim also a dual configuration, namely where the distancing position corresponds to a condition of disengagement of the first component of the helmet from the second component of the helmet, and the approaching position corresponds to a condition of engagement of the first component of the helmet with the second component of the helmet. This latter case may arise when temporary engagement between the first component and the second component is required.
What is important is that the first magnet has the same pole as the second magnet and it is therefore possible to exploit the repulsive magnetic force of the two magnets, preferably instead of the force of the spring.
It may be understood that, by actuating the second functional element, it is possible to overcome the repulsive force and a disengagement condition or, as mentioned, engagement condition, may be obtained.
In the description below reference will be preferably made, where not specified, to a situation in which said distancing position corresponds to a condition of engagement of the first component of the helmet with the second component of the helmet, namely a condition of engagement of the second functional element with a functional counter-element.
Therefore, it is clear that, by means of a helmet according to the present disclosure, it is possible to obtain advantages compared to the prior art. In particular, by using two magnets in order to facilitate the engagement of one component with the other component it is possible to reduce the space needed to accommodate the engagement system compared to the prior art, and the use of springs can be avoided. With this solution it is also possible to obtain an engagement system which can make advantageous use of the magnetic force and which may have a smaller constructional complexity and consequently require less maintenance.
Furthermore, owing to the presence of two magnets in the helmet engagement system it is possible to obtain an improved system for fastening together or engagement of two components, such as the visor or screen of the helmet, or of other two components of the helmet, since the engagement system according to the present disclosure allows fastening together or engagement, or a locking action, which is reliable and allows quick fastening/release without malfunctions of a mechanical nature, for example due to wear of the spring.
Namely, differently from the helmets of the prior art, the helmet engagement system according to the present disclosure is less subject to the risk of unintentional fastening or release and at the same it allows the user to fasten or release one component with respect to the other one, for example the screen with respect to the cap, for example in order to raise/lower the visor, in a rapid and efficient manner.
The helmet engagement system according to the present disclosure, in fact, owing to the presence of the magnets, is able to avoid the risks of jamming or wear of the mechanical components which often happens with the helmets of the prior art which are provided with even complex mechanisms for the same function. The magnets, in fact, may be configured to keep the engagement system engaged with either one of the two components, such as the screen, and at the same time allow a user to move the second functional element, pushing it towards the first functional element, in order to disengage the engagement system, for example disengage the cap from the screen and allow a displacement of either one of the first component or the second component with respect to the other one of the first component and second component in a rapid and reliable manner, with a minimum risk of undesirable movements.
This results in greater comfort for the helmet user and at the same time a greater degree of safety offered by the helmet owing to the aforementioned advantages.
Even more preferably, the first functional element is arranged in said movement seat or facing said movement seat. What is important is that the first functional element may interact magnetically with the second functional element and that the latter may slide in a guided manner in said movement seat.
For example, said engagement system is associated with one of said first component and said second component, and the second functional element comprises or is associated with an engagement element and the other one of said first component and said second component comprises an engagement counter-element, wherein said engagement element is in an engaged condition with said engagement counter-element and said second functional element is in the distancing position. It may also be understood that the type of engagement by the second functional element with the other element of the helmet may be of a varying nature, either mechanical, for example a tooth engaging in a seat, or of the magnetic type with magnets which have opposite poles.
Preferably, said engagement system is associated with the cap and the screen comprises the engagement counter-element, and said engagement condition corresponds to a condition in which said screen is in the lowered condition and the engagement counter-element of said screen is in engagement with the engagement element associated with said second functional element.
For example, said engagement element comprises a protrusion and said engagement counter-element comprises a recess configured to accommodate said protrusion. In other words, as mentioned above, the engagement may be obtained by means of a protrusion associated with the second functional element and intended to be accommodated in an engagement seat. Other forms of engagement may be envisaged, for example a magnetic-type engagement system.
Preferably, said second functional element comprises an actuation region accessible by a user for allowing said second functional element to pass from said distancing position into said approaching position. This enables the structure of the engagement system to be simplified greatly since it is sufficient to create an access area connected to the second functional element so that it may be displaced in the movement seat.
The screen may be a visor or a chin guard, or a visor associated with a chin guard, wherein said chin guard is configured to protect at least one mandibular area of the user's head.
Even more preferably, said screen is a visor and said cap comprises an upper portion configured to protect at least one frontal, parietal and occipital area of the head of a user, and a chin guard portion configured to protect at least one mandibular area of the user's head, and said engagement system is associated with said cap along said chin guard portion.
The present disclosure also relates to a method of managing a helmet comprising a first component of the helmet, a second component of the helmet and an engagement system for engaging the first component of the helmet with the second component of the helmet, said engagement system comprising a first functional element, a movement seat, and a second functional element, configured to be able to slide in said movement seat in such a way as to assume a distancing position with respect to the first functional element and an approaching position with respect to the first functional element, wherein in said distancing position said second functional element is situated further away from said first functional element than in said approaching position, wherein said first functional element comprises or is a first magnet and said second functional element comprises or is a second magnet configured to exert a magnetic force which repels said first magnet in such a way as to keep normally said second functional element in a distancing position. wherein said method comprises:

allowing said second functional element to remain in the distancing position under the action of a magnetic force of said second magnet which repels said first magnet, wherein, preferably, in said distancing position the second component is mutually engaged with said first component of the helmet;
sliding said second functional element along said movement seat so that it passes from the distancing position to an approaching position, in which said second functional element is situated closer to said first functional element than in the distancing position;
wherein, preferably, while the second functional element is in the approaching position it is possible to release said mutual engagement of the second component with respect to said first component of the helmet, or wherein while the second functional element is in the approaching position it is possible to perform said mutual engagement of the second component with respect to said first component of the helmet; preferably the first component is the cap and the second component is a protection screen configured to assume a raised condition and a lowered condition with respect to the cap;
arranging said screen in the raised condition and said second functional element in said distancing condition distanced from said first functional element;
sliding said second functional element along said movement seat so that it passes from the distancing position to an approaching position, in which said second functional element is situated closer to said first functional element than in the distancing position;
moving said screen from the raised condition to the lowered condition;
releasing said second functional element in such a way that said second magnet exerts a (mutually) repelling magnetic force in relation to said first magnet and causes said second functional element to pass from the approaching position to the distancing position and in such a way that said second functional element can determine an engagement of said screen with said cap in the lowered condition.

Even more preferably the method comprises the further steps of:

sliding said second functional element along said movement seat so that it passes from the distancing position to the approaching position, in such a way that said second functional element can determine a disengagement of said screen;
moving said screen from the lowered condition to the raised condition;

Even more preferably, the helmet of said method is that described above.
Further advantages, characteristic features and modes of use forming the subject of the present disclosure will become clear from the following detailed description of embodiments thereof, provided by way of a non-limiting example.
It is in any case clear that each embodiment forming the subject of the present disclosure may have one or more of the advantages listed above; in any case it is not required that each embodiment should have simultaneously all the advantages listed.
Reference will be made to the figures of the attached drawings in which:

Figure 5 shows an exploded view of the engagement system according to Figure 2;
Figure 6 shows a detailed cross-sectional view of the engagement system of a helmet according to an alternative embodiment, in which the second functional element is in a distancing position and the visor is in a lowered condition.

With reference to the attached figures, an embodiment of a protective helmet is denoted overall by the reference number 100.
In particular, the helmet comprises a cap 10 (shown as an example of a first component of the helmet) and a screen 20 (shown as an example of a second component of the helmet) rotatably associated with the cap 10 and configured to assume a raised condition and a lowered condition.
The cap also comprises an engagement system 30 associated with the cap 10 and comprising:

a first functional element 31, associated with the cap 10;
a movement seat 33; and
a second functional element 32, configured to be able to slide along the movement seat 33 in such a way as to assume a distancing position and an approaching position.

In particular, in the distancing position, the second functional element 32 is situated further away from the first functional element 31 than in the approaching position. Furthermore, the second functional element 32 in the distancing position is configured to engage with the screen 20 in the lowered condition, namely when the screen is situated in the lowered condition.
Furthermore, the second functional element 32 is configured to assume the approaching position so as to allow the screen 20 to pass from the lowered condition to the raised condition, or vice versa. Namely, the second functional element 32 is configured to pass from the distancing position to the approaching position, for example by means of an action performed by the helmet user, so as to allow disengagement of the screen 20 from the second functional element 32 and therefore allow the screen 20 to pass from the lowered condition to the raised condition, or vice versa.
Furthermore, the first functional element 31 comprises or is a first magnet 31a and said second functional element 32 comprises or is a second magnet 32a configured to exert a magnetic force which repels the first magnet 31a in such a way as to keep the second functional element 32 in the distancing position distanced from the first functional element 31.
Namely, the movement seat 33 is preferably configured so as to able to allow a sliding movement of the second functional element 32 between the distancing position and the approaching position. For example, the second functional element 32 may slide along the movement 33 in a direction perpendicular with respect to the cap 10 and/or the screen 20 in the lowered condition.
In other words, the repelling (and mutual) magnetic interaction between the first magnet 31a and the second magnet 32a allows the second functional element 32 to remain, in a rest condition where for example the user does not interact with the engagement system, in the distancing position where it is further away from the first functional element 31 than in the approaching condition and is able to engage with the screen 20 for example so as to keep it in the lowered condition. The second functional element 32 may also pass from the distancing position to the approaching position, by means of application of a force greater than the magnetic repelling force between the first magnet 31a and the second magnet 32a, generated for example by a user, so as to allow the disengagement, or a release, of the screen 20 from the second functional element 32, which may therefore pass from the lowered condition to the raised condition, or allow engagement, namely fastening, of the screen 20 to the second functional element 32 which may therefore pass from the raised condition to the lowered condition.
It is therefore clear that the presence of the first magnet 31a and the second magnet 32a results in an engagement system without mechanisms such as those present in the helmets according to the prior art; therefore, by means of the present disclosure it is possible to provide an engagement system which ensures engagement, for example fastening, of the screen to the engagement system which is secure and stable as well as being less subject to the risk of accidental or undesirable movements.
Preferably, when the screen passes from the raised condition to the lowered condition, the force greater than the magnetic repelling force between the first magnet 31a and the second magnet 32a may also be provided by the screen itself when it is lowered into the lowered condition, for example pushed by the user.
Preferably, the movement seat 33 is connected to, or included within, the first functional element 31. For example, therefore, the first functional element 31 and if need be the movement seat 33 are fixed to the cap 10, while the second functional element 32 is free to slide along the movement seat 33 in at least one direction, preferably perpendicular with respect to the cap 10, so as to allow the second magnet 32a to pass from the distancing position to the approaching position, or vice versa.
Preferably, the second functional element 32 comprises an engagement element 32b and the screen 20 comprises an engagement counter-element 20b. In particular, the engagement element 32b is configured to engage with the engagement counter-element 20b when the screen 20 is in the lowered condition and is engaged with the second functional element 32.
Even more preferably, the engagement element 32b comprises a protrusion and the engagement counter-element 20b comprises a recess configured to accommodate the protrusion when the screen 20 is in the lowered condition and is engaged with the second functional element 32.
For example, according to one embodiment, the engagement element 32b has a triangular form which projects from a main zone of the second functional element 32, where the end of the triangular form is configured to be able to engage inside the recess of the engagement counter-element 20b of the screen 20, at least for as long as the second magnet 32a is in the distancing position.
According to an alternative embodiment, the engagement element 32b is formed as a hook which for example projects from a main zone of the second functional element 32; for example, the hook is positioned in such a way as to be able to engage with the engagement counter-element 20b so as to keep the second functional element 32 engaged with the screen 20 for as long as the second magnet 32a is in the distancing position.
Preferably, the second functional element 32 comprises an actuation region 32 accessible by a user for allowing the second functional element 32 to pass from the distancing position to the approaching position. For example, the actuation region may be a portion of the second functional element 32 facing the outside of the helmet 100, i.e. the outside of the cap 10, and may be configured to allow a user to move the second functional element 32 along the movement seat 33 from the distancing position to the approaching position. For example, the actuation region 32c may be formed as a button which can be actuated by the user so as to push or move the second magnet 32a from the distancing position to the approaching position. Furthermore, preferably when the second magnet 32a is in the approaching position and the user releases the actuation region 32c, the repelling magnetic force of the first magnet 31a results in the return of the second magnet 32a into the distancing position.
Preferably, the screen 20 is a visor or a chin guard, or a visor associated with a chin guard, where the chin guard is configured to protect at least one mandibular area of the user's head. Namely, the second functional element 32 may be configured to engage with the visor or the chin guard, preferably in the region of the engagement counter-element 20b, so as to allow the visor and/or the chin guard to remain in the lowered condition, or preferably so as to protect the face and/or the mandibular area of the user.
According to one embodiment, the screen 20 is a visor and the cap 10 comprises an upper portion 10a configured to protect at least one frontal, parietal and occipital area of a user's head, and the cap 10 further comprises a chin guard portion 10b configured to protect at least one mandibular area of the user's head. Moreover, preferably the engagement system 30 is associated with the cap 10 along the chin guard portion 10b. Namely, in accordance with this embodiment the visor is configured to engage with the second functional element 32 in the proximity of the chin guard portion 10b of the cap 10.
The present disclosure also relates to a method of managing a helmet 100 comprising a cap 10 and a screen 20 rotatably associated with the cap 10 and configured to assume a raised condition and a lowered condition. Moreover, the helmet further comprises an engagement system 30 comprising a first functional element 31, associated with the cap 10, and a second functional element 32, for performing engagement, configured to be able to slide along a movement seat 33 of the engagement system 30.
In particular, the first functional element 31 comprises or is a first magnet 31a and said second functional element 32 comprises or is a second magnet 32a configured to exert a magnetic force which repels the first magnet 31a in such a way as to keep the second functional element 32 in a distancing position.
Furthermore, the method comprises:

arranging the screen 20 in the raised condition and the second functional element 32 in the distancing position distanced from the first functional element 31;
sliding the second functional element 32 along the movement seat 33 so that it passes from the distancing position to an approaching position, in which the second functional element 32 is situated closer to the first functional element 31 than in the distancing position;

moving the screen 20 from the raised condition to the lowered condition;
releasing the second functional element 32 in such away that the second magnet 32a exerts a magnetic force which repels the first magnet 31a and causes the second functional element 32 to pass from the approaching position to the distancing position and in such a way that the second functional element 32 engages with the screen 20 in the lowered condition.

Preferably, the method comprises the following further steps:

sliding the second functional element 32 along the movement seat 33 so that it passes from the distancing position to the approaching position, in such a way that the second functional element 32 disengages the screen 20;
moving the screen 20 from the lowered condition to the raised condition;

The subject-matter of the present disclosure has been described hitherto with reference to its embodiments. It is to be understood that other embodiments relating to the same inventive idea may exist, all of these falling within the scope of protection of the claims set forth hereinbelow.
