Definitions

  • the present invention relates to a device for hooking the visor to the cap of a helmet, and in particular to a device for hooking the visor to the cap of a helmet which allows at the same time to adjust the angular position of the visor with respect to the porthole—or window—of the cap.
  • the devices for hooking the visor to the cap of a helmet comprise pins that engage in special eyelets obtained in correspondence of the side ends of the visor and that fasten, for instance by screwing, in holes or seats obtained on the cap at the sides of the porthole.
  • Such devices are intended for ensuring the attachment of the visor to the cap, allowing at the same time the rotation of the visor with respect to the porthole.
  • these devices do not provide any adjustment of the angular position of the visor, which causes the positioning of the visor by the user to be only approximate.
  • devices are known for the adjustment of the visor with respect to the cap, or devices that allow to lock the visor in different pre-defined positions when the visor is caused to rotate to intercept or free the porthole. These devices do not provide usually the possibility of disconnecting the visor from the cap, unless by using suitable tools. Some of such devices are provided with mechanisms that, once screwed on the cap, keep, by interposition of ports, the end of the visor, in order to lock it removably in the position desired by the user. Such mechanisms, generally made up by leverages, are very complex and require both hands for their activation. Therefore, the activation of the device is particularly tiresome, as, in order to lift or to lower the visor, the user must keep the motor-cycle in balance using only his legs.
  • these devices fastened to the cap near the side ends of the porthole, are provided with a cylindrical body whereon the visor is rotatably assembled and a threaded pin which, by engaging in a hole obtained on the helmet cap, allows to keep the visor onto the cap according to an axis.
  • the cylindrical body houses a pawl elastically pushed to engage into a concavity of a rack obtained in the visor.
  • the concavities, or seats, identify different angular positions in whose correspondence the visor may be located during its rotation about the threaded pin.
  • An example of such devices is described in the British Patent Application GB 2,024,000 (Nolan S.p.A.).
  • connection of the visor to the helmet is therefore disjoined from the rotation adjusting device and may be realized, as mentioned above, with threaded pins that require the help of special tools for their assembly and disassembly.
  • Object of the present invention is to solve the drawbacks of the known art through a device for hooking the visor to a helmet cap allowing at the same time an easy adjustment of the angular position of the visor with respect to the porthole.
  • Another object of the present invention is to provide a device for hooking the visor to the cap said device being extremely simple and highly reliable, and such as to allow the rotation of the visor and the locking thereof in the desired position with one only hand.
  • Another object of the present invention is to provide a device that does not require special tools to fix or to remove the visor to or from the cap, but that, on the contrary, allows to perform such operations in any condition and with the hands only, while ensuring an extreme use safety.
  • a device for removably hooking the visor to a helmet cap of the type provided, in correspondence of each side end of the cap porthole, a guide-body for the rotation of the visor that can be engaged according to an axis in a hole of said visor, characterized in that it comprises a cursor slidingly associated to said guide-body and provided with means preventing the visor from the translation in the direction of said axis, said cursor being translatable between a position of engagement of said means holding said visor and a disengagement position, said device also comprising elastic means for pushing said cursor to said position of engagement with the visor. Thanks to this solution, the translation of the cursor suffices per se to release the visor from the cap, and therefore no tools are needed to perform such operation.
  • the cursor comprises a tooth elastically pushed to engage in a seat belonging to one or more seats obtained on the visor.
  • Said one or more seats respectively define one or more stable angular positions for the visor during the rotation movement of the latter about the axis engaging with the guide-body.
  • the above position of disengagement of the holding means coincides with an end of stroke position of the cursor, in such a manner that no accidental unhooking of the visor can take place.
  • the elastic means suitable to push the cursor to the engagement position of the means for holding the visor comprise a helical spring interposed between the cursor and the circular body.
  • the aforesaid tooth is obtained integrally with the cursor, and the elastic means that push the cursor to an engagement position with the visor also push the tooth to one or more seats obtained in the visor.
  • FIG. 1 is an exploded view of a hooking device according to a preferred embodiment of the present invention
  • FIG. 2 a , 2 b are schematic views of a helmet provided with the device according to the present invention, with a hooked respectively unhooked visor;
  • FIG. 3 is a perspective view of the cursor according to a particular aspect of the present invention.
  • FIG. 4 is a perspective view of a guide-body whereon the cursor of FIG. 3 can be slidingly associated.
  • FIGS. 1 - 4 show a preferred embodiment of the device according to the present invention, to removably hook to cap 3 visor 2 of interception of a porthole, or window, 22 of a helmet 4 , i.e. a device that allows to connect or disconnect visor 2 to or from cap 3 , allowing at the same time the rotation of said visor 2 with respect to porthole 22 .
  • the device according to the present invention comprises, for each portion of cap 3 located near the side ends of porthole 22 , a guide-body 5 tied to cap 3 whereon visor 2 rotatably engages according to an axis by means of a hole 23 .
  • the guide-body 5 allows the rotation of visor 2 about an axis substantially orthogonal with respect to the walls of cap 3 and prevents any movement transversal to said rotation axis of said visor 2 .
  • a cursor 7 provided with holding means 8 of visor 2 in the direction of the above axis and translatable between a position wherein the holding means 8 engage with visor 2 to prevent it from sliding along the rotation axis, and a position wherein means 8 are disengaged from visor 2 .
  • the rotation axis of visor 2 defined by the coupling between hole 23 and the guide-body 5 , by the term “axial”, while by the expression “axial holding means of the visor” there will be intended to indicate the above defined holding means 8 .
  • the device according to the present invention comprises also elastic means 25 intended for pushing cursor 7 , and therefore the axial holding means 8 , in engagement with visor 2 .
  • helmet 4 has, on the sides of cap 3 , near each side end of porthole 22 , a circular-plan cylindrical guide unit that by engaging in the circular hole 23 of visor 2 , acts as a pin to allow the rotation of visor 2 on porthole 5 , allowing thereby the opening and closing of visor 2 on porthole 22 .
  • the circular guide-body comprises, in a transversal position with respect to the rotation axis, a groove 6 wherein cursor 7 , provided with axial holding means 8 , is slidingly inserted and can translate between an engagement position of the holding means 8 with visor 2 , shown on FIG. 2 a , and a disengagement position, shown on FIG. 2 b .
  • the circular guide unit 5 has, as mentioned above, in a position diametrically opposed with respect to the axial holding means 8 , a contrast protrusion 18 .
  • the holding means, coupled with contrast protrusion 18 allow, when cursor 7 is in engagement position, to hook visor 2 to helmet cap 3 , preventing it from sliding along the rotation axis, moving away from said cap 3 .
  • a cylindrical helical spring 25 that constitutes the elastic means suitable to push cursor 7 to the aforesaid engagement position.
  • spring 25 is located between a pin 26 of the guide-body 5 and a abutment 27 of cursor 7 .
  • the stroke of cursor 7 defined by groove 6 , and the overall size of the holding means 8 allow to disconnect visor 2 from the guide-body 5 only when cursor 7 reaches an end-of-stroke position (disengagement position) opposed to the aforesaid engagement position of means 8 with visor 2 .
  • end-of-stroke position disengagement position
  • visor 2 disconnects visor 2 from cap 3 only in the position of cursor 7 shown in FIG. 2 b , so that any accidental unhooking of visor 2 from cap 3 is prevented.
  • Cursor 7 has, as a translation activating means, a protrusion 11 which, moved by hand by user, allows the shifting of said cursor towards the disengagement position of holding means 8 of visor 2 , overcoming the action of spring 25 .
  • the means of axial holding 8 of visor 2 may be constituted by a protrusion of cursor 7 that extends, in a substantially orthogonal way with respect to the rotation axis, above cap 3 , for a length and at a distance from cap 3 such as to allow the housing of the surface of visor 2 adjoining hole 23 between the protrusion (i.e. the holding means 8 ) and cap 3 .
  • the holding means are constituted by a fork-shaped appendix 12 of cursor 7 , whose upper arm prevents, by contrast of parts, visor 2 from sliding axially when cursor 7 is in its engagement position (FIG. 2 a ).
  • the external surface 15 of the upper arm 13 of fork 12 is, according to a particular aspect of the present invention, inclined towards the rear side of the cap, in order to allow an easy disengagement of hole 23 of guide-body 5 , when cursor 7 has reached the end-of-stroke position, shown in FIG. 2 b.
  • the lower arm 14 of fork 12 engages in an aperture 16 (FIG. 4) obtained in the guide-body 5 , in such a way that the size of said opening 16 defines the stroke width for cursor 7 .
  • Aperture 16 opposite to the engagement position with visor 2 , houses pin 26 that supports an end of the cylindrical helical spring 25 .
  • cursor 7 has also a tooth 9 elastically pushed in engagement with one of seats 10 obtained on visor 2 .
  • Seats 10 that belong to a rack (or toothing) preferably realized along the internal profile of hole 23 , define a plurality of stable angular positions for said visor 2 , allowing the adjustment of its rotation, by serial locations, by user.
  • tooth 9 during the rotation of visor 2 about the engagement axis with the guide-body, alternately engages in seat 10 of the rack obtained along the internal profile of hole 23 , so as to shift within prefixed positions of the rotation for said visor 2 .
  • tooth 9 is integrally realized with cursor 5 and protrudes from the latter, transversally to the rotation axis of visor 2 , so as to engage one of seats 10 of hole 23 , when cursor 7 is in its engagement position with visor 2 (FIG. 2 a ).
  • the cylindrical helical spring 26 by pushing cursor 7 and the holding means 8 to engage with a portion of visor 2 , pushes also tooth 9 into one of seats 10 .
  • tooth 9 is located between the arms of fork 12 (see FIG. 3), in such a way that the engagement of fork 12 with the surface of visor 2 adjoining hole 23 involves as a consequence the engagement of tooth 9 with one of seats 10 .
  • Tooth 9 and seats 10 of the rack obtained along the internal perimeter of hole 23 have a complementary tapered saw tooth profile, that facilitates the rotation and the adjustment of the angular position of visor 2 .
  • the tapered profile of-seats 10 helps the coming out of tooth 9 from said seats and causes the partial translation of cursor 7 towards its disengagement portion from visor 2 , without the latter being ever reached, overcoming only partly the pushing exercised by spring 25 .
  • the rotation of visor 2 by user, about the axis defined by guide-body 5 involves, thanks to the complementary tapered profiles of seats 10 and tooth 9 , the partial translation of cursor 7 and the holding means 8 towards the aforesaid disengagement position of cursor 7 , which however is never reached, overcoming only partly the pushing exercised by spring 25 .
  • pin 9 is substantially in correspondence of another of seats 10 of hole 23
  • spring 25 pushes tooth 9 into such subsequent seat, determining the reaching of a prefixed angular stable position of visor 2 with respect to porthole 22 .
  • the number of seats 10 obtained on the internal profile of hole 23 depends on the number of angular positions wherein it is expected, in the design step, that visor 2 will be stably located during its opening and closing movement. Obviously, the profile of eyelet 23 might be provided with one only seat 10 , for instance in correspondence of the maximum opening position of visor 2 .
  • the guide-body 5 is provided with a protrusion 18 which, superposed to visor 2 when the latter is tied to guide-body 5 , contrasts any shift along the rotation axis of said visor 2 , abutting on a position opposed to fork 12 of cursor 7 and in particular, in the case of a circular-plan guide-body 5 , it extends in a position diametrically opposite with respect to the engagement position of cursor 7 with visor 2 .
  • guide-body 5 may be provided with recesses 29 , or holes, wherein tangs or other structural coupling elements belonging to removable accessories of the helmet, such as a front or aerodynamic appendixes or a sun shading flange may be housed.
  • a cursor 7 is first translatably tied in groove 6 , so that the lower arm 14 of fork 12 inserts into opening 26 .
  • groove 6 may be so shaped as to allow the snap-insertion of cursor 7 , by means, for instance, of elastically strainable portions, and to prevent cursor 7 from shifting axially.
  • the cylindrical helical spring 25 is located between pin 26 and the abutment surface 27 of cursor 7 .
  • guide-body 5 (see FIG. 1) is coupled to a corresponding cavity shaped in cap 3 and fastened thereto by means of a partly threaded element 19 (screw or bolt) that engages in a seat, also threaded, integral with cap 3 .
  • Element 19 may be a pin provided with a T-shaped head that inserts into an eyelet 20 of cursor 7 , allowing its transversal sliding, and into a through-hole 28 of unit 5 . Said pin 19 , that does not involve visor 2 , needs not being removed to allow visor 2 to be disconnected from cap 3 .
  • eyelet 23 of the visor is inserted on the cylindrical guide-body 5 , causing the latter to position frontally beyond contrast protrusion 18 realized thereon; afterwards, by acting by hand on protrusion 11 of cursor 7 , the front part of hole 23 of visor 2 inserts automatically on the cylindrical guide-body 5 and, once cursor 7 is released, it is held up by means 8 , or the upper arm 13 of fork 12 .
  • the partly threaded element 19 may be replaced by any other mechanism or element that, according to the known art, would allow to stably fasten unit 5 to cap 3 .
