Definitions

  • the present invention relates to a safety helmet, particularly suitable for motorcycle use, of the type provided with a chin guard firmly constrained to the helmet shell, that can be removed by acting on appropriate constraining means.
  • the presented safety helmet comes abreast of the traditional motorcycle integral helmets, provided with chin guard integrated into the shell, and the so-called “jets" with no chin guard, as well as helmets provided with removably chin guard.
  • controls of the constraining means of the chin guard to the shell can be operated externally to the helmet. This entails a serious risk that, after a fall, external bodies which may impact a helmet can act in an extremely dangerous way on controls of the constraining means of the chin guard. Such an event could cause the release of the chin guard from the shell, thus offering less protection to the helmet user.
  • the chin guard once removed, can also be replaced by specific protecting plates only for a purely aesthetic function, indeed hiding the portion of the shell fitting into the chin guard.
  • the used constraining means require rather difficult operations in order to create both the connection and the release of the chin guard from the shell, that is the user is required for a considerable handicraft, resulting in the need of having also have a considerable available space inside the helmet as well as a substantial time to execute the helmet configuration change.
  • these constraining means are generally rather bulky, which means that moving parts must be assembled almost solely on the chin guard, and they reduce or in any case penalize thicknesses of the inner layers for shock absorption, such as for example, EPS layers and/or comfort paddings or the like, and especially not being easy and quick to use.
  • the object of the present invention is, therefore, to realize a helmet of the type comprising a chin guard removable from the shell and provided with the release command inside the helmet, but where the inner bulk due to the internal constraining means is reduced, even though ensuring a highly secure connection as well between chin guard and shell, or protecting plates and shell, instead of the chin guard.
  • a further object of the present invention is to realize a helmet, of the type above described, in which the ability to change the product configuration can be carried out quickly and by simple operations, not requiring special manual skills.
  • a still further object of the present invention is to realize a helmet of the above described type, i.e. provided with the release control arranged inside the helmet, but where the thickness of inner paddings is identical to that of integral helmets, or those helmets provided with the release control outside the helmet.
  • the helmet, object of the present invention comprising a shell, a chin guard, or at least one protecting plate, and means for removably constraining said chin guard, or said at least one protecting plate, to said shell, said constraining means comprising at least one mobile element provided with at least one portion for retaining said chin guard, or said at least one protecting plate, from sliding relatively to said shell, and vice versa, and with at least one portion for controlling the movement of said at least one mobile element relatively to said shell, or to said chin guard, or to said at least one protecting plate, between an engagement and disengagement positions of said at least one retaining portion with said chin guard, or with said at least one protecting plate, or with said shell, in correspondence to at least one fixing area of said chin guard, or said at least one protecting plate, or said shell, characterized in that said at least one mobile element is disposed, at least partially, inside at least one through opening obtained in said shell, or said chin guard, or said at least one protecting plate, and that said at least one controlling portion and
  • this helmet offers the almost impossibility of being activated accidentally by bodies external to the helmet, with which it would impact as a result of dangerous events such as, for example, a fall from the motorcycle.
  • the only way to separate the shell from the chin guard is to act on the controlling portion from the inside, and preferably only when the helmet is not worn by the user.
  • said at least one mobile element comprises a rotatable lever rigidly constrained to said shell, or to said chin guard, between said engagement position and said disengagement position, or vice versa.
  • the lever includes a fulcrum element, selected from a pin, a screw, a bush, a rivet or similar, that is constrained to said shell, or to said chin guard.
  • said fulcrum is disposed between said at least one retaining portion and said at least one controlling portion, In this way, the lever takes a configuration with two arms.
  • the portion of the controlling element must be disposed relatively to the opening so that the user can operate it from the inside of the helmet, whereas the retaining portion must be placed relatively to the opening so that it could engage with the afore mentioned fixing area disposed on the chin guard, or shell, depending on where the constraining means are disposed, in any case outside the shell, or chin guard.
  • said constraining means comprise, as well, elastic means for returning said at least one mobile element into at least its engagement position with said shell, or said chin guard.
  • elastic means for returning said at least one mobile element into at least its engagement position with said shell, or said chin guard.
  • these elastic means can also be of the bistable type, i.e. they are able to maintain the two positions of engagement and disengagement permanently once reached.
  • the helmet 1 is provided with a shell 2, accommodating and protecting the user's skull, and with a chin guard 3, able to provide protection at the chin.
  • the chin guard 3 and the shell 2 are mutually constrained through appropriate means 4 to removably constrain said chin guard 3 and said shell 2.
  • these constraining means 4 comprise, in each side 100a, 100b (the latter not being represented in the appended figures) of the helmet 1, a mobile element 5 able to counter the reciprocal translation of the chin guard 3 relatively to the shell 2.
  • the mobile element 5 is able to counter the described slide, or translation, between the chin guard 3 and the shell 2 through a retaining portion 6, of which it is provided with, able to engage firmly with the chin guard 3, at a fixing area 8 present on the chin guard 3 itself.
  • said mobile element 5 comprises a rotatable lever rigidly constrained to said shell 2.
  • said lever 5 comprises a fulcrum element 9 constrained, or hinged, to the shell 2.
  • the implementation of the fulcrum 9 can be of various kinds, among which, for example, a pin, a screw, a bush, a rivet and in general any means able to ensure the rotation of the mobile element 5 are mentioned.
  • the controlling portion 7 comprises an element jutting from the lever 5 so that it can be easily grasped by the user to disengage the chin guard 3 to the shell 2.
  • the controlling portion 7 can be operated by the user imposing on it a force allowing the rotation thereof around the fulcrum 9 between at least one locking, or engaging, position, in which the retaining portion 6 engages with the chin guard 3 at the appropriate fixing area 8, and at least one disengaging position, in which the retaining portion 6 is released, or disengaged, from the fixing area 8, as shown in Figure 4 .
  • the controlling portion 7 is disposed inside the helmet 1, in the correspondence of a surface 1a thereof, so that it can not be activated accidentally as a result of collisions against external bodies, or of inadvertent operations, thereby causing the separation from the chin guard 3 of the shell 2. More precisely, the controlling portion 7 can be operated only by removing some inner components of the helmet, not shown here, such as EPS layers for the absorption and/or comfort paddings, also having the role to prevent accidental pressures operating from the inside from causing the chin guard release - for example due to relative compression that cheeks of the driver's head may, in case of impact, apply against the same inner walls.
  • some inner components of the helmet not shown here, such as EPS layers for the absorption and/or comfort paddings, also having the role to prevent accidental pressures operating from the inside from causing the chin guard release - for example due to relative compression that cheeks of the driver's head may, in case of impact, apply against the same inner walls.
  • the mobile body 5 is disposed, at least in part, within a through opening 11 obtained in the shell 2.
  • the controlling portion 7 and the retaining portion 6 are operatively disposed, respectively, on the inner 11 a and the outer 11 b faces of the opening 11.
  • inner face 11a means the face of the opening facing inside the helmet 1
  • outer face 11b means the face facing outside the helmet.
  • the controlling portion 7 of the lever 5 takes up an area inside the helmet, whereas the retaining portion 6, also of the lever 5, engaging with the chin guard 3 at the appropriate fixing area 8, is disposed in an area between the shell 4 and the chin guard 3 and, however, outside of the shell 2. Consequently, the lever 5 is hidden inside the shell 2, in a through opening 11 thereof, limiting the bulk inside the controlling portion 7 only. It is understandable therefore that in order for the lever 5 to occupy the described areas, one possible solution is to obtain a through opening 11 on the shell 2, through which it can be arranged to engage with the chin guard 3, and to be able, at the same time, to be operated from the inside of the helmet 1. At the same time, outside of the helmet with the assembled chin guard, the lever 5 and in particular its retaining portion 6 is protected and faired by the chin guard itself preventing accidental or inadvertent presses from causing the undesired release of the device.
  • the constraining means 4 are conveniently provided with an element 14 minimizing the movement, or rotation, of the mobile element 5 in its operating range, as in the case of the described implementation, when it is located near the engaging position of said mobile element 5 with said chin guard 3.
  • the countering portion 13 of the mobile element 5 is advantageously obtained by means of a recess, in the shape of step, obtained in the mobile element 5 (see Figure 7 ).
  • a recess 13 is able to be coupled, because of shape, with the afore mentioned minimizing element 14 realized on the shell 2, greatly increasing the minimizing effect of the travel of the lever 5.
  • the particular arrangement of the countering portion 13 on the lever 5, i.e. disposed between said retaining portion 6 and said fulcrum 9, is such to increase the tightening between the shell 2 and the chin guard 3 just in case wherein a tractive force trying to separate the two components of the helmet 1 is exerted. In essence, in case wherein a tractive force for separating the shell 2 from the chin guard 3 is applied, the moment generated on the mobile element would be compensated by the moment generated on the mobile element 5 by the constrain between the minimizing element 14 and countering portion 13.
  • the movement of the mobile element 5 is adjusted, as mentioned, by the user, through the appropriate controlling portion 7.
  • said constraining means 4 comprise elastic means 12 able to retain said lever 5 in its engagement position, thus ensuring a stable fixing of the chin guard 3 to the shell 2.
  • These elastic means 12 can be of different kind as long as they are able to give to the mobile element 5 at least a force directed towards the fixing area 8 of the chin guard 3, thereby returning the lever to the engage with the chin guard 3, or the shell 2.
  • the elastic means 12, in the alternative embodiments not represented, may comprise elastic bistable means, that is able to permanently retain the mobile element 5 in an engagement or disengagement position, according to the starting position of the mobile element 5.
  • a spring made of borrow material has been selected, even if it is possible to obtain elastic and/or mobile means from at least one prominence of the shell 2 and/or the chin guard 3.
  • said constraining means 4 comprise means 99 for flexural stiffening of the connection between said shell 2 and said chin guard 3.
  • These stiffening means 99 comprise at least two parts 100, 101, 102 and 200, 201, 202 reciprocally engageable and respectively integral with said shell 2 and said chin guard 3.
  • such stiffening means 99 comprise a plurality of guides 100, 101 and 102, made integrally with said chin guard 3, engageable into a plurality of corresponding seats 200, 201 and 202 integrally obtained with said shell 2.
  • a first guide 100 is L-shaped or hook - shaped, and it can be coupled to a corresponding seat 200 obtained in the shell 2
  • a second guide 102 is T-shaped, or wedge- shaped, and it can be coupled because of shape to a corresponding seat 202 realized in the shell 2.
  • both the L-shaped guide 100 and the T-shaped guide 102 are arrange one another so that they can be connected to the respective seats 200 and 202 only when the lever 5 is in its disengagement position with the fixing area 8.
  • the mobile element 5 of the constraining means 4 in the shape of chin guard 3 connected to the respective shell 2, is arranged between said L-shaped guide 100 and said T-shaped guide 102.
  • the constraining means above described comprising, further to the mobile element, the stiffening means too, allow to obtain an extremely compact and resistant helmet.
  • the lever has a strong resistance against the separation between the shell and the chin guard in the case of tractive forces acting onto the chin guard and / or the shell, whereas the stiffening means operate in the case of moments able to force the chin rotation relatively to the shell.
  • the assembling of the chin guard to the shell is made as follows. After having moved the chin guard 3 near the shell 2, by the afore said guides 100, 101 and 102, by pressing the chin guard 3 against the shell 2 at the opening 11 and in particular at the retaining portion 6 of the lever 5, thanks to said sliding area 50 present in said third guide 101, the rotation of said lever 5 is caused, and it becomes possible to start engaging the second T-shaped guide 102 inside the shell 2 and, simultaneously, the first L-shaped guide 100 can start engaging the seat 200 of the shell 2.
  • the use simplicity of the device is evinced in conjunction with the achievement of a durable and reliable helmet structure without the need to have relevant spaces.
  • the particular embodiment allows the helmet provided with chin guard to appear like a normal integral helmet, both externally and internally: all elements of the device cannot in fact be reached directly or, otherwise, they are not visible because they are hidden from the usual layers of shock-absorbing or comfort coating materials.
  • the helmet 1 can be modified to allow its use in jet configuration, that is with no chin guard 3, as shown in Figures 10 and 11.
  • side plates 90 can be arranged realizing de facto, on each of two distinct sides 100a and 100b (here not shown), a coupling similar to that above described for assembling the chin guard 3, although the function of these plates 90 is to transform the helmet configuration with removable chin guard to helmet of "jet" type.
  • the plates 90 replace the chin guard 3, but without substantial changes to the technical elements so far described and claimed, in particular regarding the constraining means 4 and its opening 11 that hold exactly the same considerations techniques above carried out for the first embodiment of the helmet 1.
