- connection device including a base body associated with the helmet shell and an engaging lever inserted inside a corresponding seat in the base body.
- the lever has a lever end which engages with a corresponding portion of the visor.
- connection device is disclosed in WO 2007/112 990 A1 .
- This operating procedure although advantageous in many respects, nevertheless has a number of drawbacks which have not yet been resolved.
- connection device consists in the complexity of assembling and disassembling the lever on/from the base body and the difficulty of operating the lever in order to disconnect the visor from the shell.
- connection device is large in size and heavy, which affects the whole helmet, with negative consequences for the person wearing the helmet.
- connection device with a structure which is able to overcome the drawbacks of the prior art and/or achieve further advantages and also the provision of a helmet including this device.

- connection device is defined in the corresponding dependent claims.
- connection device is understood as meaning that the device allows connection of a first element to a second element of the helmet and at the same allows, if necessary, disconnection of the first element from the second element; it therefore consists of a removable or reversible connecting system.
- connection device With the connection device according to the present disclosure significant advantages may be achieved.
- a first advantage consists in the possibility of easy operation of the slider in order to disconnect the first element from the second element of the helmet.
- Another advantage consists in the possibility of limiting the weight and the size of the device and avoiding the use of heavy metal springs or large-size levers.
- a further advantage is also achieved both in terms of production, owing to the limited time needed for assembly of the slider with the base body, and subsequently in the event of exchange or replacement.
- a further advantage consists in the possibility of adjusting as required the elastic deformability of the slider (for example by means of modification of the slider structure or the material used) in order to achieve varied operation (different engaging force, different force which must be applied for disengagement).

- the base body 20 and the slider 22 are made of acetal resin, polycarbonate, ABS or a similar material with a suitable mechanical strength.
- the base body 20 includes, in addition to the seat 26 for the slider 22, also a seat for rotation 28 for the visor 16.
- the seat for rotation 28 is substantially formed by two curved recesses, 28a and 28b, in the form of a circle segment.

- the spring element 30 is intended to be deformed during operation of the slider 22, in relation to the rest of the slider 22 which is not deformed.
- the grip element 33 is therefore arranged between the engagement element 23 and the spring element 30.
- the spring element 30 in the example is a compression spring and comprises two arms 32a, 32b each forming an appendage of a respective lateral extension 34, 35 and converging towards the longitudinal axis S on the opposite side to the engagement element 23.
- the grip element 33, the two lateral extensions 34, 35, and the engagement element 23 form a ring inside which a cavity 37 is defined.
- This cavity 37 is intended to receive a user's finger, for example the index finger, which is inserted inside the cavity 37 so as to exert a force on the grip element 33 in the direction of the longitudinal axis S on the opposite side to the engagement element 23.
- a grip element 33 and a spring element 30 are incorporated in the same body of the slider 22.
- the slider 22 includes, formed in each lateral extension 34, 35, near the grip element 33, two shoulders 34a, 35a or abutting surfaces.

- the end appendage 123 has a curved or concave profile, in the example a circle segment, and is intended to retain stably by means of pressing contact the pin member 24 of the shell 16.
- the curved shape of the end appendage 123 allows a rotational movement of the shell 14 about the axis X without hindering rotation.
- the slider 22 is intended to be inserted inside the seat 26 of the base body 20.
- the slider 22 is able to be inserted inside the seat 26, underneath the plane of the sheet, before fixing the entire connection device 10 to the shell 14.
- the seat 26 of the base body 20 intended to house the slider 22 is symmetrical along an axis S', which is a longitudinal axis of the base body 20.
- the seat 26 includes a first zone 26a, including a first bottom side 126a and a bottom projection 126b arranged in an L-shape ( Figure 8 ) and intended to cooperate in abutment with the ends 132a, 132b of the spring element 30.
- the seat 26 also includes a second side 226a and a third side 226b which are parallel to each other and to the axis S' and against which the two lateral extensions 34, 35, respectively, of the slider 22 are intended to be arranged resting.
- the two lateral extensions 34, 35 are positioned resting on a respective inner face 326a, 326b of the second side 226a and the third side 226b, namely, with reference to Figure 2 , a face directed underneath the plane of the sheet, which, during operation, when the device 10 is mounted on the helmet 12, is directed towards the shell 14.
- the second side 226a and the third side 226b define at the respective ends, on the part facing the first bottom side 126a, two respective inclined surfaces 226c, 226d, against which the two shoulders 34a, 35a of the slider 22 are intended to be placed in abutment.

- the seat 26 includes a second zone 26b intended to receive the engagement element 23 of the slider 22.
- the base body 20 includes a bridge element 27 which connects two opposite sides 20a, 20b of the base body 20 and separates in fact the seat 26 for the slider 22 from the seat for rotation 28.
- the end appendage 123 rests on the bridge element 27, on top of the latter.
- the end appendage 123 rests on a top surface 127 of the bridge element 27.

- the ends 132a, 132b of the spring element 30 are arranged on top of the bottom projection 126b and the two lateral extensions 34, 35 are arranged underneath the respective second side 226a and third side 226b, while the engagement element 23 is positioned on top of the bridge element 27.
- This arrangement of the slider 22 ensures a stable connection between the slider 22 and the base body 20 and a stable guided displacement of the slider in relation to the base body 20 parallel to the axes S, S'. This consists of the so-called engagement position.
- this includes, as mentioned, two curved recesses 28a, 28b, each extending over a circle segment which subtends an angle of about 115°.
- the base body 20 includes a central element 29, which is substantially disc-shaped, and an outer circular rim 30, partially coinciding with the abovementioned bridge element 27, and connected on opposite sides to the central element 29 by means of connecting appendages 31 a, 31 b.
- each recess 28a, 28b is widened within the outer circular rim 30 by means of a respective curved niche 128a, 128b.
- the two niches 128a, 128b are substantially aligned along said longitudinal axis S', and are symmetrical in relation to the latter.
- Each niche 128a, 128b defines in the base body 20 two retaining walls 40, 41 which are respectively arranged on diametrically opposite sides of the central element 29 and therefore the axis of rotation X.
- pin member 24 in the example it is formed as one piece with the visor 16, for example by means of moulding.
- the pin member 24 has an oblong and tapered form including a first portion 45 which is ring-shaped, of greater width or diameter, provided with said projections 24a, 24b, and a second portion 46 of smaller width.
- the projections 24a, 24b each have an L shape and extend on opposite sides of the axis of rotation X of the first ring-shaped portion 45.
- Each projection 24a, 24b is intended to cooperate with a respective niche 128a, 128b and with a corresponding retaining wall 40, 41 of the base body 20.
- the pin member 24 is completed by a cylindrical stud 50 or cylinder piece, projecting from the sheet with reference to Figure 4 .
- the visor portion 16 is viewed from the inside, namely from the side intended to face the shell 14.
- the stud 50 extends at right angles from the surface of the pin member 24, in particular of the second portion 46, on the side directed towards the base body 20, along an axis Y parallel to the axis of rotation X.
- the stud 50 is formed as one piece with the pin member 24, but it is also possible for it to be formed as a structurally independent part.
- the stud 50 forms the interaction element designed to cooperate with an interaction counter-element 55 associated with the base body 20 (as shown in Figures 10 and 11 ) and removable if required.
- the interaction counter-element 55 is a small plate which is structurally independent of the base body 20 and connected to it, along the outer circular rim 30, by means of connection ( Figure 12 ).
- the base body 20 includes a slit 56 ( Figure 6 and Figure 12 ) which has an arc-like shape extending along a circle arc and intended to receive a lug 57 which has a shape matching that of the slit 56, projecting at right angles from the side of the interaction counter-element 55.
- the lug 57 is intended to be inserted by means of elastic deformation inside the slit 56, passing underneath the base body 20 between the latter and the protective shell 14.
- the interaction counter-element 55 (shown in detail in Figures 12, 13, 14 and 15 ) is made of plastic which has a predefined flexibility and elasticity (in the example PC or ABS), so as to undergo suitable elastic deformation following pressing contact of the stud 50.
- the interaction counter-element 55 is retained between the base body 20 and the stud 50.
- the interaction counter-element 55 is a crescent-shaped insert and has a profile 59 intended to be placed in contact with a cylindrical side surface of the stud 50.
- the profile 59 extends substantially along an arc of a circle which, when the counter-element 55 is mounted on the base body 20, has its centre coinciding with the axis of rotation X of the pin member 24.
- the profile 59 making contact with the stud 50 has two recesses or niches 60, 61, in the form of a circle arc, formed at the ends of the profile 59.
- the two recesses 60, 61 are intended to receive the stud 50 and respectively define a start-of-travel position of the pin member 24, in a first operating position of the visor 16, when the latter is situated opposite the user's face, and an end-of-travel position of the pin member 24, in a second or fully raised position of the visor 16, when the latter is situated opposite the user's forehead.
- the pin member 24 and the base body 20 have dimensions such that, when the projections 24a, 24b are inserted into the corresponding recesses 128a, 128b of the seat for rotation 28 and along the retaining walls 40, 41, the stud 50 is positioned in pressing contact against the profile 59 of the interaction counter-element 55, such that the interaction counter-element 55 is subject, as mentioned, to a slight elastic deformation by the stud 50.
- the stud 50 and the interaction counter-element 55 are therefore parts which are able to generate friction, during rotation of the visor 16 and the movement of the pin member 24; namely, the stud 50 and the profile 59 rub against each other and generate a friction force which slightly resists the movement, with a suitable force, so as to be able to position the visor 16 also in an intermediate position between the two abovementioned positions.
- connection device 10 With reference to Figures 6 to 11 , a mode of application of the connection device 10 according to the present disclosure is now described.
- the slider 22, which is initially separated from the base body 20, is inserted underneath the base body 20, in the arrangement described above and visible in Figures 6 and Figures 8 and 9 . As mentioned above, this arrangement allows both stable seating and guided sliding ( Figure 7 ) of the slider 22 inside the seat 26 of the base body.
- the device 10 is then joined to the shell 14, for example is positioned inside the special housing 15 formed on the outer surface of the shell 14 and is fixed there by means of screws 21.
- the slider 22 is retracted towards the first bottom side 126a of the seat 26, so that the spring member 30 is compressed and deformed against the first side 126a of the seat 26, causing flexing of the two arms 32a, 32b ( Figure 7 ). Retraction of the slider 22 is performed manually by operating the grip element 33. In this condition a so-called disengagement position of the slider 22 is obtained.
- the pin member 24 is inserted so that the L-shaped wings of the two curved projections 24a, 24b fit inside the niches 128a, 128b of the recesses 28a, 28b.
- the slider 22 is released from the retracted position or condition, so that the spring element 30 returns elastically into the initial condition (i.e. the undeformed or less deformed condition) and pushes the slider 22 towards the seat for rotation 28, until the shoulders 34a, 35a of the slider come into abutment against the respective inclined surfaces 226c, 226d. Therefore, the engagement element 23 surmounts with the end appendage 123 the curved projection 24b which is located inside the recess 28b, in particular inside the niche 128b; in other words, the end appendage 123 is arranged between the curved projection 24b and the plane of the pin member 24. In this way, extraction of the pin member 24 from the seat for rotation 28 is prevented and connection between the pin member 24 (fixed to the visor 16) and the base body 20 (fixed to the shell 14) is ensured.
- the initial condition i.e. the undeformed or less deformed condition
- the interaction counter-element 55 includes a central hole or opening 63, which also has a weight-reducing function ( Figures 12 to 15 ).
- the stud 50 passes over a small hump 65, 66, respectively, which, once passed by, produces, as a result of a slight vibration caused by elastic deformation, a click sound.
- This sound allows the user to "sense", i.e. hear, when the end-of-travel or start-of-travel positions of the pin member 24 and therefore the two positions of the visor 16 have been reached.
- interaction counter-element 55 is removably associated with the base body 20, there is the possibility of replacing this interaction counter-element 55 with another interaction counter-element which is made of a different material or has a different thickness or geometry.
- the material, thickness and geometry are among the most important variables, the combination of which results in a wide variation of the characteristics of the interaction counter-element 55.
- the interaction counter-element 55 according to Figure 13 may be replaced if necessary by another interaction counter-element 155, 255, such as that shown in Figure 14 or Figure 15 , respectively.
- the embodiments according to Figures 14 and 15 show interaction counter-elements 155, 255 which include, along the profile 159, 259, a plurality of humps 170, 270 and depressions 171, 271, which are arranged between the two recesses 60, 61.
- the parts and the components of the interaction counter-element 155, 255 which have the same function and structure in the interaction counter-element 55 described above retain the same reference number and therefore are not described again in detail.
- the embodiment according to Figure 14 shows an interaction counter-element 155, the humps 170 and depressions 171 of which are lightly formed, while in the embodiment according to Figure 15 the humps 270 and the depressions 271 are more well-defined and form a kind of toothed segment along the respective profile 259.
- the material, the thickness and the number of humps 170, 270 and depressions 171, 271 on the interaction counter-element 155, 255 are suitably chosen so as to obtain a given movement (which is harder or easier, with greater or lesser resistance) of the pin member 24 relative to the base body 20, if necessary also with the abovementioned given sound.
- a given movement which is harder or easier, with greater or lesser resistance
- the user has to exert a greater force in order to move the visor 16 and also hears a click sound which is well defined and louder than that of the first embodiment 55, in the start-of-travel and end-of-travel positions, and for each hump 170, 270 which the stud 50 passes over.
- interaction counter-element 55 described above with another interaction counter-element (not shown in the drawings) having the same geometry and made of the same material, but with a greater thickness, it is possible to obtain a greater area of contact/friction with the stud 50, and therefore a greater resistance to movement.
- This modification may be useful in the case where a user wishes to feel or hear more clearly a greater force required to operate the visor 16 between the two start-of-travel and end-of-travel positions and if it is desired to obtain stable positioning of the visor 16 also in an intermediate position between start and end of the travel movement.
- connection device 10 is therefore obtained where the movement of the visor 16 is accompanied in a regular and rhythmic manner by a well-defined sound and/or by a greater force required on the part of the user.
- connection is removable and therefore the visor may be easily removed from the helmet 12, for example for maintenance or replacement.
- the visor 16 is rotated until the curved projections 24a, 24b are disengaged from the respective retaining walls 40, 41 and are situated inside the niches 128a, 128b of the recesses 28a, 28b.
- the user by operating the grip element 33, causes retraction of the slider 22 towards the first bottom side 126a of the seat 26 so that the spring element 30 is compressed and deformed against the first side 126a of the seat 26, while the engagement element 23 frees the recess 28b.
- the curved projections 24a, 24b may be extracted from the seat for rotation 28 and the visor 18 is then removed from the shell 14.
- connection device according to the present disclosure has been described hitherto with reference to its preferred embodiments.

Description
- The present disclosure relates in general to a connection device for a helmet. In particular the present disclosure relates to a connection device for a helmet for connecting a first element of the helmet to a second element of the helmet, and vice versa; for example, in a helmet including a visor and a shell, the connection device is able to connect the visor to the shell in a stably connected condition, or for example in a helmet including a chin bar or a top protection guard, the connection device is able to connect the chin bar, or top guard, to the shell, or also is able to connect similar elements or parts of the helmet.
- In the description below, for simpler and clearer illustration, reference will be made in particular to the use of a connection device in which said device is intended to provide the connection between the visor (forming said first element) and the helmet shell (therefore forming the second element).
- In this connection, in a helmet, it is known to use a connection device including a base body associated with the helmet shell and an engaging lever inserted inside a corresponding seat in the base body. The lever has a lever end which engages with a corresponding portion of the visor.
- By operating the lever it is possible to release the connection between the lever end and the visor and therefore remove the visor from the helmet shell.
- Such a connection device is disclosed in
WO 2007/112 990 A1 . This operating procedure, although advantageous in many respects, nevertheless has a number of drawbacks which have not yet been resolved. - One drawback of the known connection device consists in the complexity of assembling and disassembling the lever on/from the base body and the difficulty of operating the lever in order to disconnect the visor from the shell.
- A further drawback consists in the fact that the connection device is large in size and heavy, which affects the whole helmet, with negative consequences for the person wearing the helmet.
- One technical problem forming the basis of the present disclosure consists in the provision of a connection device with a structure which is able to overcome the drawbacks of the prior art and/or achieve further advantages and also the provision of a helmet including this device.
- This is achieved by providing a connection device for a helmet as defined in the independent claim 1 and by a helmet as defined in
claim 14. - Secondary features of the abovementioned connection device are defined in the corresponding dependent claims.
- In connection with the present disclosure the expression "connection device" is understood as meaning that the device allows connection of a first element to a second element of the helmet and at the same allows, if necessary, disconnection of the first element from the second element; it therefore consists of a removable or reversible connecting system.
- With the connection device according to the present disclosure significant advantages may be achieved.
- A first advantage consists in the possibility of easy operation of the slider in order to disconnect the first element from the second element of the helmet.
- Another advantage consists in the possibility of limiting the weight and the size of the device and avoiding the use of heavy metal springs or large-size levers.
- A further advantage is also achieved both in terms of production, owing to the limited time needed for assembly of the slider with the base body, and subsequently in the event of exchange or replacement.
- A further advantage consists in the possibility of adjusting as required the elastic deformability of the slider (for example by means of modification of the slider structure or the material used) in order to achieve varied operation (different engaging force, different force which must be applied for disengagement). Basically, by providing a cursor which is elastically deformable (at least partly), during production it is possible to modify rapidly the degree of the engaging force to be applied to the first element of the helmet by simply modifying the material or the structure of the slider. In fact the deformability may be adjusted both by modifying the structure of the slider and by modifying the material of the slider.
- By providing an elastically deformable slider it is also possible to reduce the time needed to define the force to be applied to the slider for disengagement of the engagement means from the first element of the helmet.
- Preferably the slider is formed as a single body. With such an embodiment it is possible to reduce further the number of components in the connection device.
- In one embodiment the slider comprises, incorporated in said single body, a spring element, i.e. a part of the slider or an element intended to be deformed in relation to the rest of the slider.
- Even more preferably, the device comprises, incorporated in said single body, a grip element arranged between the engagement means and the spring element, so that by operating said grip element a user causes a movement of said engagement means away from the first element of the helmet and a consequent deformation of the spring element. This grip element helps to ensure easy manual operation of the slider by the user of the helmet in order to release the engagement of said engagement means with the first element of the helmet.
- Preferably the slider is symmetrical in relation to a longitudinal axis and, even more preferably, the slider comprises, along said longitudinal axis, said engagement means, two lateral extensions extending parallel to, and on opposite sides of, the longitudinal axis, said grip element extending between the two lateral extensions and transversely in relation to the longitudinal axis, and the spring element. This embodiment has the advantage of controlling displacement of the slider in its corresponding seat and at the same time deformation of the spring element. Further advantages, characteristic features and modes of use of the connection device and the helmet according to the present disclosure will become clear from the following detailed description of preferred embodiments, provided by way of a non-limiting example.

reference number 10 denotes a connection device according to the present disclosure. - In particular, in the example shown in the figures, the
connection device 10 is applied to ahelmet 12 including ashell 14 for protecting a user's head and avisor 16 and is intended to connect removably, i.e. reversibly, the visor in relation to theshell 14 of thehelmet 12. In the example shown, thevisor 16 is mounted rotatably in relation to theshell 14 about an axis X and in particular is rotatable between a first position in which saidvisor 16 is situated in the zone of the user's face, so as to perform a protective function (as shown inFigure 1 in continuous lines, and inFigure 10 ), and a second position in which it is raised in the zone of the user's forehead (as shown inFigure 1 in broken lines, and inFigure 11 ), passing through a series of intermediate positions. - More particularly, two
connection devices 10, only one of which is visible inFigure 1 , are associated with thehelmet 12, saidconnection devices 10 being arranged on the outer side of theshell 14 on opposite sides in the so-called temple regions of the user's head, namely along the sides of thehelmet 12 which protect the temple zones of the user's head. The axis X extends between one temple region and the other one and is the same for both theconnection devices 10. - In the present description below, for the sake of simpler illustration, only one
connection device 10 is described, i.e. that device which is located in the right-hand temple region of the user, as can be seen in schematic and exploded form inFigure 1 a. - In the example, the
connection device 10 comprises a base body 20 (Figure 1 a,Figure 2 ), or support plinth or base, forming a first part of theconnection device 10 and fixed on the outside of theshell 14 to the aforementioned right-hand temple region, inside arespective seat 15 formed on the outer surface of theshell 14, and a slider 22 (Figure 3 ) forming a second part of theconnection device 10. - The
base body 20 is firmly fixed to theshell 14 by means of screws 21 (Figure 1 ) or similar fixing elements, and theslider 22 is housed inside a seat, which is generally denoted by thenumber 26 and is formed in thebase body 20. Basically thebase body 20 is a partially hollow structure which acts as a housing for theslider 22. Thebase body 20, in addition to acting as seat for housing theslider 22, also acts as a guide for displacement of theslider 22, as will be explained more fully below. - In the example, the
base body 20 and theslider 22 are made of acetal resin, polycarbonate, ABS or a similar material with a suitable mechanical strength. - In the example, the
base body 20 includes, in addition to theseat 26 for theslider 22, also a seat forrotation 28 for thevisor 16. In particular, in the example, the seat forrotation 28 is substantially formed by two curved recesses, 28a and 28b, in the form of a circle segment. Each of the twocurved recesses corresponding pin member 24 of thevisor 16, in the example is intended to receive correspondingcurved projections pin member 24 is made of acetal resin, polycarbonate or ABS. Essentially thebase body 20 is shaped so as to house, not only theslider 22, but also thepin member 24 of thevisor 16 and allow rotation of the latter about the axis X. - According to the present disclosure, the
slider 22 is elastically deformable, at least partially, so as to allow the reversible operations of connecting and removing/separating thevisor 16 from theshell 14 and vice versa. - In this connection, the
slider 22 includes a single body which is symmetrical in relation to a longitudinal axis S, namely an axis which coincides with a direction of longitudinal extension. In particular, theslider 22 comprises, along said axis S, anengagement element 23 intended to retain thepin member 24 inside the seat forrotation 28, twolateral extensions grip element 33 which extends transversely in relation to the axis S (namely in the manner of a bridge) between the twolateral extensions spring element 30. - The
spring element 30 is intended to be deformed during operation of theslider 22, in relation to the rest of theslider 22 which is not deformed. - The
grip element 33 is therefore arranged between theengagement element 23 and thespring element 30. - The
spring element 30 in the example is a compression spring and comprises twoarms lateral extension engagement element 23. - As can be seen in
Figure 3 , thegrip element 33, the twolateral extensions engagement element 23 form a ring inside which acavity 37 is defined. Thiscavity 37 is intended to receive a user's finger, for example the index finger, which is inserted inside thecavity 37 so as to exert a force on thegrip element 33 in the direction of the longitudinal axis S on the opposite side to theengagement element 23. - In other words, a
grip element 33 and aspring element 30 are incorporated in the same body of theslider 22. - The
slider 22 includes, formed in eachlateral extension grip element 33, twoshoulders shoulders engagement element 23. - It can also be seen, from
Figure 8 , that theengagement element 23 has an L-shaped section including anend appendage 123 which constitutes a wing of the L and defines a shoulder 123a. - The
end appendage 123 has a curved or concave profile, in the example a circle segment, and is intended to retain stably by means of pressing contact thepin member 24 of theshell 16. In particular, as will be illustrated in detail below, the curved shape of theend appendage 123 allows a rotational movement of theshell 14 about the axis X without hindering rotation. - As mentioned above, the
slider 22 is intended to be inserted inside theseat 26 of thebase body 20. - Even more particularly, with reference to
Figures 2 and 3 , theslider 22 is able to be inserted inside theseat 26, underneath the plane of the sheet, before fixing theentire connection device 10 to theshell 14. - The
seat 26 of thebase body 20 intended to house theslider 22 is symmetrical along an axis S', which is a longitudinal axis of thebase body 20. Theseat 26 includes afirst zone 26a, including a firstbottom side 126a and abottom projection 126b arranged in an L-shape (Figure 8 ) and intended to cooperate in abutment with theends spring element 30. - The
seat 26 also includes asecond side 226a and athird side 226b which are parallel to each other and to the axis S' and against which the twolateral extensions slider 22 are intended to be arranged resting. In particular, as can be seen inFigure 9 , the twolateral extensions inner face 326a, 326b of thesecond side 226a and thethird side 226b, namely, with reference toFigure 2 , a face directed underneath the plane of the sheet, which, during operation, when thedevice 10 is mounted on thehelmet 12, is directed towards theshell 14. - The
second side 226a and thethird side 226b define at the respective ends, on the part facing the firstbottom side 126a, two respectiveinclined surfaces shoulders slider 22 are intended to be placed in abutment. - Basically, the
slider 22 when it is housed inside theseat 26 has the twolateral extensions Figure 2 ) the respectivesecond side 226a andthird side 226b, and theends spring element 30 arranged above thebottom projection 126b. In other words, when thedevice 10 is mounted on thehelmet 12, thelateral extensions shell 14 and the respectivesecond side 226a andthird side 226b, while thebottom projection 126b is arranged between theshell 14 and theends - The
seat 26 includes a second zone 26b intended to receive theengagement element 23 of theslider 22. - In the zone 26b, the
base body 20 includes abridge element 27 which connects twoopposite sides base body 20 and separates in fact theseat 26 for theslider 22 from the seat forrotation 28. - When the
slider 22 is inserted into theseat 26, theend appendage 123 rests on thebridge element 27, on top of the latter. Basically, in relation to the plane of the sheet according toFigure 2 , theend appendage 123 rests on atop surface 127 of thebridge element 27. Moreover, said shoulder 123a, i.e. an inner portion of theengagement element 23, is placed in abutment against thebridge element 27, on the opposite side to the seat forrotation 28. - Basically, when the
slider 22 is housed inside theseat 26, theends spring element 30 are arranged on top of thebottom projection 126b and the twolateral extensions second side 226a andthird side 226b, while theengagement element 23 is positioned on top of thebridge element 27. This arrangement of theslider 22 ensures a stable connection between theslider 22 and thebase body 20 and a stable guided displacement of the slider in relation to thebase body 20 parallel to the axes S, S'. This consists of the so-called engagement position. - As regards the seat for
rotation 28, this includes, as mentioned, twocurved recesses - Between the two
curved recesses base body 20 includes acentral element 29, which is substantially disc-shaped, and an outercircular rim 30, partially coinciding with theabovementioned bridge element 27, and connected on opposite sides to thecentral element 29 by means of connectingappendages - It can also be seen that, along the axis S', each
recess circular rim 30 by means of a respectivecurved niche niches - Each
niche base body 20 tworetaining walls central element 29 and therefore the axis of rotation X. - As regards the
pin member 24, in the example it is formed as one piece with thevisor 16, for example by means of moulding. - The
pin member 24 has an oblong and tapered form including afirst portion 45 which is ring-shaped, of greater width or diameter, provided with saidprojections second portion 46 of smaller width. Theprojections portion 45. Eachprojection respective niche corresponding retaining wall base body 20. - The
pin member 24 is completed by acylindrical stud 50 or cylinder piece, projecting from the sheet with reference toFigure 4 . In particular, inFigure 4 , thevisor portion 16 is viewed from the inside, namely from the side intended to face theshell 14. - In particular, the
stud 50 extends at right angles from the surface of thepin member 24, in particular of thesecond portion 46, on the side directed towards thebase body 20, along an axis Y parallel to the axis of rotation X. - In the example the
stud 50 is formed as one piece with thepin member 24, but it is also possible for it to be formed as a structurally independent part. - The
stud 50 forms the interaction element designed to cooperate with aninteraction counter-element 55 associated with the base body 20 (as shown inFigures 10 and 11 ) and removable if required. - The
interaction counter-element 55 is a small plate which is structurally independent of thebase body 20 and connected to it, along the outercircular rim 30, by means of connection (Figure 12 ). - In order to perform the connection, in the example shown, the
base body 20 includes a slit 56 (Figure 6 andFigure 12 ) which has an arc-like shape extending along a circle arc and intended to receive alug 57 which has a shape matching that of theslit 56, projecting at right angles from the side of theinteraction counter-element 55. Thelug 57 is intended to be inserted by means of elastic deformation inside theslit 56, passing underneath thebase body 20 between the latter and theprotective shell 14. - More particularly, the interaction counter-element 55 (shown in detail in
Figures 12, 13, 14 and 15 ) is made of plastic which has a predefined flexibility and elasticity (in the example PC or ABS), so as to undergo suitable elastic deformation following pressing contact of thestud 50. - Essentially, the
interaction counter-element 55 is retained between thebase body 20 and thestud 50. Even more particularly, with reference toFigure 12 , theinteraction counter-element 55 is a crescent-shaped insert and has aprofile 59 intended to be placed in contact with a cylindrical side surface of thestud 50. Theprofile 59 extends substantially along an arc of a circle which, when the counter-element 55 is mounted on thebase body 20, has its centre coinciding with the axis of rotation X of thepin member 24. - It should also be pointed out that the
profile 59 making contact with thestud 50 has two recesses orniches profile 59. The tworecesses stud 50 and respectively define a start-of-travel position of thepin member 24, in a first operating position of thevisor 16, when the latter is situated opposite the user's face, and an end-of-travel position of thepin member 24, in a second or fully raised position of thevisor 16, when the latter is situated opposite the user's forehead. Thepin member 24 and thebase body 20 have dimensions such that, when theprojections recesses rotation 28 and along the retainingwalls stud 50 is positioned in pressing contact against theprofile 59 of theinteraction counter-element 55, such that theinteraction counter-element 55 is subject, as mentioned, to a slight elastic deformation by thestud 50. - The
stud 50 and theinteraction counter-element 55 are therefore parts which are able to generate friction, during rotation of thevisor 16 and the movement of thepin member 24; namely, thestud 50 and theprofile 59 rub against each other and generate a friction force which slightly resists the movement, with a suitable force, so as to be able to position thevisor 16 also in an intermediate position between the two abovementioned positions. - With reference to
Figures 6 to 11 , a mode of application of theconnection device 10 according to the present disclosure is now described. - The
slider 22, which is initially separated from thebase body 20, is inserted underneath thebase body 20, in the arrangement described above and visible inFigures 6 andFigures 8 and 9 . As mentioned above, this arrangement allows both stable seating and guided sliding (Figure 7 ) of theslider 22 inside theseat 26 of the base body. - The
device 10 is then joined to theshell 14, for example is positioned inside thespecial housing 15 formed on the outer surface of theshell 14 and is fixed there by means ofscrews 21. - In order to allow insertion of the
pin member 24 of thevisor 16, in particular thecurved projections pin member 24, inside the seat forrotation 28, theslider 22 is retracted towards the firstbottom side 126a of theseat 26, so that thespring member 30 is compressed and deformed against thefirst side 126a of theseat 26, causing flexing of the twoarms Figure 7 ). Retraction of theslider 22 is performed manually by operating thegrip element 33. In this condition a so-called disengagement position of theslider 22 is obtained. - In this condition, the
engagement element 23 frees part of therecess 28b and allows insertion of thepin member 24. - In particular, the
pin member 24 is inserted so that the L-shaped wings of the twocurved projections niches recesses - Then the
slider 22 is released from the retracted position or condition, so that thespring element 30 returns elastically into the initial condition (i.e. the undeformed or less deformed condition) and pushes theslider 22 towards the seat forrotation 28, until theshoulders inclined surfaces engagement element 23 surmounts with theend appendage 123 thecurved projection 24b which is located inside therecess 28b, in particular inside theniche 128b; in other words, theend appendage 123 is arranged between thecurved projection 24b and the plane of thepin member 24. In this way, extraction of thepin member 24 from the seat forrotation 28 is prevented and connection between the pin member 24 (fixed to the visor 16) and the base body 20 (fixed to the shell 14) is ensured. - By rotating then the
visor 16 in relation to theshell 14, the L-shaped wings of thecurved projections respective retaining walls - At the same time the
stud 50 exerts a pressing contact against theprofile 59 until it reaches one or other of the tworecesses interaction counter-element 55 includes a central hole oropening 63, which also has a weight-reducing function (Figures 12 to 15 ). - It should be noted that, in order to be seated inside either one of the two
recesses stud 50 passes over asmall hump pin member 24 and therefore the two positions of thevisor 16 have been reached. - It should also be noted that, since the
interaction counter-element 55 is removably associated with thebase body 20, there is the possibility of replacing thisinteraction counter-element 55 with another interaction counter-element which is made of a different material or has a different thickness or geometry. The material, thickness and geometry are among the most important variables, the combination of which results in a wide variation of the characteristics of theinteraction counter-element 55. - Basically, the
interaction counter-element 55 according toFigure 13 may be replaced if necessary by anotherinteraction counter-element Figure 14 or Figure 15 , respectively. - For example, the embodiments according to
Figures 14 and 15 show interaction counter-elements 155, 255 which include, along theprofile humps depressions recesses Figures 14 and 15 , the parts and the components of theinteraction counter-element interaction counter-element 55 described above retain the same reference number and therefore are not described again in detail. - In particular, the embodiment according to
Figure 14 shows aninteraction counter-element 155, thehumps 170 anddepressions 171 of which are lightly formed, while in the embodiment according toFigure 15 thehumps 270 and thedepressions 271 are more well-defined and form a kind of toothed segment along therespective profile 259. - The passing movement of the
stud 50 over eachhump depression - Essentially, the material, the thickness and the number of
humps depressions interaction counter-element pin member 24 relative to thebase body 20, if necessary also with the abovementioned given sound. Basically, by using aninteraction counter-element 155 and even more so aninteraction counter-element 255, the user has to exert a greater force in order to move thevisor 16 and also hears a click sound which is well defined and louder than that of thefirst embodiment 55, in the start-of-travel and end-of-travel positions, and for eachhump stud 50 passes over. - Moreover, by replacing the
interaction counter-element 55 described above with another interaction counter-element (not shown in the drawings) having the same geometry and made of the same material, but with a greater thickness, it is possible to obtain a greater area of contact/friction with thestud 50, and therefore a greater resistance to movement. This modification may be useful in the case where a user wishes to feel or hear more clearly a greater force required to operate thevisor 16 between the two start-of-travel and end-of-travel positions and if it is desired to obtain stable positioning of thevisor 16 also in an intermediate position between start and end of the travel movement. - A
connection device 10 is therefore obtained where the movement of thevisor 16 is accompanied in a regular and rhythmic manner by a well-defined sound and/or by a greater force required on the part of the user. - It must also be pointed out, as mentioned above, that the connection is removable and therefore the visor may be easily removed from the
helmet 12, for example for maintenance or replacement. - For this purpose, the
visor 16 is rotated until thecurved projections respective retaining walls niches recesses grip element 33, causes retraction of theslider 22 towards the firstbottom side 126a of theseat 26 so that thespring element 30 is compressed and deformed against thefirst side 126a of theseat 26, while theengagement element 23 frees therecess 28b. At this point, thecurved projections rotation 28 and the visor 18 is then removed from theshell 14. - The connection device according to the present disclosure has been described hitherto with reference to its preferred embodiments.
- It is understood that there may exist other embodiments which relate to the same inventive concept, all of these falling within the scope of protection of the claims provided below.
