Definitions

  • the present invention relates to spectacles to be attached to a helmet and to a helmet fitted with such spectacles.
  • the technical field of the invention is that of the manufacturing of spectacles.
  • the invention in particular is applied to helmets of drivers or passengers of fast transportation vehicles, such as motorcyclists' helmets.
  • helmets generally include an external stiff cap, an internal cap (or small cap) covering a substantial portion or the totality of the internal face of the external cap, as well as a lining covering the internal face of the internal cap; the latter is thicker and stiffer than the external cap, and is generally moulded in a plastic such as expanded polystyrene.
  • a transparent plastic screen which is attached to the external cap so as to be able to switch from a retracted configuration to an active configuration; this switching is generally obtained by rotating the screen, by means of the presence of two substantially diametrically opposite pivots which provide the link between the cap and the screen.
  • This type of stiff screen which retracts against the internal face or against the external face of the cap, in the active position (eye protection), extends over several centimetres, in front of the eyes of the wearer of the helmet; in this position, wind and dust may notably rush into the free space separating the screen from the face of the wearer; the screen therefore only imperfectly fulfils its eye protection function, especially when the helmet lacks any chin strap joining the cheeks of the cap.
  • Patent EP15796 a ski helmet with a retractable screen, was described, wherein the screen has a lower cut intended to rest on the nose of the wearer; the screen is joined to a jointed hoop at the cap, by an elastic tab which urges the screen towards the inside of the helmet; the hoop forms a half circle with a radius less than that of the external cap; it slides inside a space delimited by the respective front (frontal) portions of the external and internal caps; the hoop is extended by two levers jutting out from the lower edge of the cap; the helmet further includes two ramps for guiding the side edges of the screen which are formed in the front portion of the internal cap.
  • the presence of a front hollow space separating the external cap from the internal cap reduces the shock absorption capacity by the front portion of the helmet; moreover, the presence of protruding side levers under the cheeks of the helmet, which are required for causing the pivoting of the hoop bearing the screen, may cause discomfort for the user.
  • the elastic joining tab of the screen to the hoop has a limited capacity of adaptation to different configurations of faces of users, likely to be encountered; consequently, in any case, with this pad, the edges of the screen cannot be pressed around the eyes of the wearer of the helmet.
  • the presence of guiding ramps requires the manufacture of a specially dimensioned helmet for a screen with given dimensions, or conversely, the manufacture of a screen specially designed for a determined helmet model and size.
  • Document FR-A-2717046 describes another device for retracting a visor inside a helmet.
  • An object of the invention is to propose retractable spectacles for helmets and helmets with spectacles, which are improved.
  • An object of the invention is to find a remedy, at least in part, to the drawbacks of the known systems for attaching and/or adapting spectacles or retractable screen(s) to a helmet.
  • a device for attaching spectacles to a helmet with two branches each fitted with a means—such as a pivot—for attachment to the helmet wherein each branch is deformable and/or jointed, and includes means for bringing the spectacles back towards the means for attachment to the helmet, so that the amplitude of the back movement of the spectacles towards the inside of the helmet may be large and may thus be adapted to very varied face configurations of the wearer.
  • the support of spectacles essentially formed by both (left and right) pivoting branches is compact and may easily be designed so as to exhibit with the spectacles which it supports a low aerodynamic drag coefficient; thus, this support is preferably designed in order to slide (during its pivoting) on the external face of the external cap of the helmet.
  • the forces for bringing the spectacles back towards the face of the wearer which are distributed and/or applied on either side of the spectacles, promote intimate contact of the spectacles with the portions of the face surrounding the eyes of the helmet's wearer.
  • each of the return means has an elastic deformation capacity over a large amplitude (or travel) (in particular over an amplitude at least equal to 10 mm); in particular, each return means preferably includes a spiral metal spring.
  • each of the branches is telescopic, i.e., it includes two branch portions which may slide by remaining nested in each other, for example one around the other, which portions are jointed and brought back toward each other by said spring or return means.
  • a device for attaching spectacles to a helmet by two branches pivotally: mounted relatively to the helmet and joined to the eye screen(s) by a deformable link, in which each branch includes pressing means for pressing (and/or applying) a portion of the branch adjacent to the eye screen(s), against a portion of the section of a cheek of the cap (and/or the helmet); these means facilitate application of the spectacles against the face of the wearer.
  • each of the branch portions is preferably joined to the screen side edge by a deformable link, in particular by a joint including a pivot, a hinge or a ball joint.
  • each of the branches preferably includes a first joint joining said telescopic portion of the branch (which is fitted with a pivot for attachment to the cap) to said branch portion adjacent to the screen;
  • each branch includes:
  • spectacles to be attached on a helmet by two branches including two screens or screen portions or monocular ophthalmic lenses which are joined by a hasp including a lower cut, in which the hasp is provided with a means (such as a pivot or a hinge with a substantially vertical axis) for mutual pivoting of both screens or both screen portions; this allows the face including both screens or screen portions to assume a first configuration in which the relative inclination of the screens or lenses is adapted to the morphology of the face of the wearer, as well as a second configuration in which the relative inclination of the screens or lenses is adapted to the curvature of the external face of the external cap; with this, the spectacles may be intimately pressed against the face in the active position, and they may be pressed against the cap in the retracted position.
  • a means such as a pivot or a hinge with a substantially vertical axis
  • spectacles to be attached onto a helmet including a binocular screen or two binocular screens and a mounting for joining the screen(s) to the helmet;
  • the spectacles include two branches which are each fitted with a pivot for attaching to the helmet;
  • each branch includes a deformable structure preferably including two mobile portions relatively to each other and a return spring which tends to fold, bend and/or shorten each branch, in order to press the screen(s) against the face of the helmet's wearer.
  • the screen(s) or lens(es) are firmly attached to a central gripping appendage facilitating displacement of the optical screen(s) by the wearer of the helmet and of the spectacles, single-handed; this appendage preferably extends above the hasp and the face, and/or in the extension of the latter; the appendage may for example assume the shape of a horizontal bar joining both monocular screens.
  • the device according to the invention for assembling spectacles to the cap provides adjustment and automatic adaptation (in depth) of the position of the spectacles relatively to the cap; the wearer (notably a motorcyclist) may easily and rapidly retract the spectacles over the front portion of the helmet and thereby clear his/her field of vision, in the case of emergency; this adaptation is particularly facilitated when each branch includes two pivot or ball joint hinges, which allow at least a translational displacement of the spectacles relatively to the helmet along two or three axes or directions; this double joint facilitates retraction of the spectacles outside the helmet as well as application of the spectacles against the face of the wearer.
  • the spectacles according to the invention may easily be fitted with filtering and/or corrective glasses or lenses, which may be firmly attached to the mounting, in a removable way, in order to facilitate their replacement.
  • FIG. 1 schematically illustrates, in a sectional view through a horizontal anterioposterior plane, a preferred embodiment of spectacles according to the invention, which are firmly attached to a helmet and in an active position for protecting the eyes of the wearer (not shown).
  • FIG. 2 illustrates, in a perspective view, a motorcyclist wearing a helmet fitted out with retractable spectacles according to the invention having a similar structure to that of the spectacles of FIG. 1 .
  • FIG. 3 schematically illustrates, in a perspective view from the side, the helmet of FIG. 2 , the spectacles of which are retracted.
  • FIG. 4 is a view, at an enlarged scale, of a telescopic portion of a branch of the spectacles of FIG. 1 .
  • FIG. 5 is a view similar to that of FIG. 2 , which illustrates an alternative embodiment of a mounting according to the invention which is fitted with removable lenses.
  • FIG. 6 is a view similar to that of FIG. 2 , which illustrates an alternative embodiment of a mounting according to the invention, which covers a pair of corrective spectacles worn by the wearer of the helmet.
  • the pair of spectacles fitting out the helmet 1 includes two monocular screens 2 and 3 which are joined by a hasp in two portions 4 , 5 joined along a vertical axis 6 , by means of a hinge 15 integrated into the hasp and joining both portions.
  • Each of both spectacle branches include three main parts: a first part 7 , 8 with an elongated shape along axis 51 , is joined by its internal end 41 , 42 , to the respective side edge 2 a , 3 a , of the glasses or screens 2 , 3 , via a hinge 30 with a vertical axis 10 , i.e., substantially parallel to the joint axis 6 of the hasp; a second part 20 with the shape of a substantially horizontal axis rod 52 , is fitted at its rear end with a stop 53 ( FIG.
  • the whole has a symmetry along an anterioposterior median vertical plane, the trace of which is located as 50 in the plane of FIG. 1 .
  • the third branch portion 21 includes a longitudinal recess 54 receiving the rod 20 and provided with a face 55 for supporting the front end of a spiral spring 23 ; this spring with axis 52 , which extends around the rear portion of the rod 20 , between the stop 53 fitting this rod and the stop 55 fitting the recess 54 , tends to bring the rod 20 back towards the rear (towards the joint pivot 18 of the mounting relatively to the helmet); because of the link between parts 20 and 7 ( 8 , respectively), this spring also brings part 7 ( 8 , respectively) back towards the pivot 18 , as well as the screen of spectacles firmly attached to the latter, while allowing them to move away from the pivot 18 : under the effect of a forward traction exerted by the wearer of the helmet, in order to retract the spectacles on the external front portion of the external cap of the helmet, spring 23 is compressed between stops 53 and 55 , as the telescopic portion 20 , 21 of the branch is stretched out.
  • each part 7 , 8 is provided with a bevelled sliding supporting face 40 , i.e., inclined (by an angle close to 45 degrees) relatively to the longitudinal axis 51 of the part 7 , 8 ;
  • the front end of each part 21 is provided with a bevelled sliding supporting face 45 , i.e., inclined (for example, by an angle close to 45 degrees) relatively to the longitudinal axis 52 of the part 21 ;
  • the wearer may grasp the central portion of the mounting, single-handed, via an appendage firmly attached to the hasp or via a horizontal bar 60 ( FIG. 2 ) surmounting and joining lenses 2 and 3 ; the wearer pushes apart the lenses from his/her face by a forward traction movement, and then retracts the spectacles by a rear traction movement towards the top of the helmet, by deployment of each of the branches made possible by the mutual translational and rotational movements of the three main parts of the each branch, up to the retraction position illustrated in FIG. 3 ; in this position, the lower (nose) cut of the hasp may cooperate with a stop 14 or a similar means for holding the spectacles in the retracted position.
  • the internal face 49 of each part 21 preferably has a curvature identical with (or close to) that of the external face of the external cap in the area surrounding the pivot 18 ; the face 49 may further include a means—such as pads—for promoting sliding of this face against the cap 11 .
  • the rod 20 and the recess 54 of the part 21 may also be curved according to a radius close to the radius of curvature of the external face of the cap, so that the mounting may be fitted with a pivoting branch 21 portion, the thickness of which is reduced, in order to reduce its wind catching.
  • the rod 20 may be replaced with a blade or metal strip, for example.
  • each of both lenses of the mounting as illustrated for lens 3 may be detached from the arch 70 and the hasp 5 of the mounting, by switching, according to the arrow illustrated in this figure, from the firmly attached position to the mounting illustrated in dotted lines, to a detached configuration illustrated in continuous lines; conversely, firm attachment of the lens to the mounting may be obtained by fitting it in a groove provided in portions 4 , 5 , 70 of the mounting.
  • the mounting according to the invention fitted with both of its lenses 2 , 3 covers the lenses 80 of a pair of ordinary spectacles worn by the wearer of the helmet, by surrounding the latter and protecting the eyes of the latter; for this purpose, the mounting portion encircling the lenses 2 , 3 , is preferably provided on its internal face facing the face of the wearer, with a deformable spacer such as a bead or fold (reference 90 in FIG. 1 ) made in a compressible material such as synthetic foam.
  • a deformable spacer such as a bead or fold
