Definitions

  • the present disclosure relates in general to a connection device for a helmet.
  • 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.
  • 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).
  • 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 for a helmet as defined in the independent claim 1 and by a helmet as defined in claim 14.
  • 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).
  • a cursor which is elastically deformable (at least partly)
  • the deformability may be adjusted both by modifying the structure of the slider and by modifying the material of the slider.
  • 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.
  • 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.
  • 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.
  • 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.
  • each embodiment of the device according to the present disclosure may have one or more of the abovementioned advantages; in any case it is not necessary that each embodiment should have simultaneously all the advantages listed.

  • 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 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.

  • 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 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.
