Definitions

  • a helmet be provided with two movable visors one of which is clear and the other of which is tinted. Such an arrangement protects the wearers eyes against injury from fragments and the like and protects the eyes from glare.
  • visors are mounted on tracks and are provided with knobs which can be moved to slide the visors along the tracks. Some of them rely on friction to hold the visor in adjusted position.
  • assemblies of the prior art are more or less effective they embody a number of defects. First, many of them are relatively complicated for the result achieved thereby. Those assemblies of the type employing tracks in which the lenses ride are apt to become fouled along a line of contact, resulting in difficulty in moving them to a desired position. No means generally are provided for positively holding the lens in an adjusted position.
  • the assemblies of the prior art are not as simple to operate as is desired.
  • the assemblies of the prior art are tailored to suit a particular helmet and are not adapted to be applied to a variety of helmets.
  • the visor housing in many cases forms a part of the operating assembly so that as a result of damage to the housing the entire assembly may be rendered inoperative.
  • One object of our invention is to provide a universal dual visor assembly which overcomes the defects of visor assemblies of the prior art.
  • Another object of out invention is to provide a universal dual visor assembly which is adapted to be applied to a wide variety of helmets.
  • a further object of our invention is to provide a universal dual visor assembly which is easily operated with one hand.
  • Still another object of our invention is to provide a universal dual visor assembly the lenses of which may individually selectively be locked in various positions.
  • a still further object of our invention is to provide a universal dual visor assembly which is simple in construction and which is inexpensive to manufacture.
  • Yet another object of our invention is to provide a universal dual visor assembly which is not subject to line fouling.
  • a still further object of our invention is to provide a universal dual visor assembly which is durable.
  • our invention contemplates the provision of a universal dual visor assembly in which a pair of lenses are supported by hollow shafts carried by the helmet, which shafts have bores of noncircular cross section for receiving pushbuttons of corresponding noncircular cross section for movement between shaft-locking positions at which locking elements on the pushbuttons selectively engage in recesses on the shaft support to lock the shaft in selected positions and release positions at which the shafts are free to turn.
  • One of the visors is coupled to one of the shafts for rotation therewith while being free to rotate on the other shaft while the other lens is coupled to the other shaft for rotation therewith while being free to rotate on the one shaft so that the lenses can individually and selectively be moved between retracted and extended positions in response to actuation of the respective pushbuttons and rotation of the respective shafts.
  • FIG. 1 is a front elevation of a helmet provided with our universal dual visor assembly.
  • FIG. 2 is a fragmentary side elevation of our assembly taken along the line 22 of FIG. 1.
  • FIG. 3 is a sectional view of our universal dual visor assembly taken along the line 33 of FIG. 2.
  • FIG. 4 is a fragmentary sectional view of the locking mechanism of our universal dual view visor assembly taken along the line 4-4 of FIG. 3.
  • FIG. 5 is a fragmentary sectional view similar to FIG. 4 of a modified fonn of locking mechanism for our universal dual visor assembly.
  • FIG. 6 is a fragmentary sectional view of the left-hand operating mechanism of our universal dual visor assembly taken along the line 66 of FIG. 3.
  • FIG. 7 is a fragmentary sectional view of the right-hand operating assembly of our universal dual visor assembly.
  • the assembly 10 includes a right-hand operating mechanism 14 and a left-hand operating mechanism 16 which respectively position a clear lens 18 and a tinted lens 20, in a manner which will be apparent from the description hereinafter, in retracted positions beneath a shield 22 or in extended positions in front of the wearers eyes.
  • the clear lens 18 may be made of any suitable material preferably we form the lens from a clear polycarbonate resin which, as is known in the art, has a high impact resistance.
  • the outer tinted lens 20 may for example be neutral gray and may be formed from any suitable material such for example as stretched acrylic resin.
  • the assembly 16 includes a shaft mounting bracket 30 having a peripheral flange 32 for receiving screws 34 which engage fittings 36 in the wall of the helmet 12 to hold the bracket 30 in position.
  • a hollow shaft 38 extends through an opening 40 in bracket 30.
  • a flange 42 on shaft 38 is retained within the bracket 30.
  • shaft 38 with a bore 46 having a noncircular crosssectional shape to receive a pushbutton 48 having a similar cross-sectional shape so that when shaft 38 turns pushbutton 48 will turn with the shaft.
  • the pushbutton 48 with a plurality of radially outwardly extending legs 50 the ends of which carry bosses 52.
  • the undersurface of the top of bracket 30 with a plurality of recesses 54 adapted to receive bosses 52.
  • a spring 56 located within the pushbutton 48 is received in a spring positioner 58 so as to urge the pushbutton outwardly of the assembly to urge the bosses 52 toward the undersurface of bracket 30. It will be appreciated that with the bosses 52 disposed in the recesses 54 shaft 38 cannot be turned.
  • the normal movement required to shift one of the lenses between its retracted position and its extended position is approximately 90.
  • the pushbutton 48 with four legs 50 spaced at 90 each to the other. Further we form four spaced recesses 54 in the underside of the bracket 30 for receiving the lugs or bosses 52.
  • a positive locking action is provided after 90 of movement of the shaft 38.
  • pushbutton 56 has been depressed and the shaft has rotated slightly the button may be released and the lugs 52 engage the portions of the underside of the top of bracket 30 between recesses 54.
  • This frictional engagement preferably is sufiiciently strong that some force is required to turn the shaft 38 to bring the parts into locked positions.
  • FIG. 5 we have shown an alternate embodiment of the locking mechanism in which we provide a pushbutton 60 with eight spaced legs 62 carrying lugs 64 adapted to engage in recesses 66 in the underside of the top of the bracket 30.
  • the shaft can be locked in an intermediate position between fully extended and retracted.
  • eight legs 62 we might use only two or four of such legs.
  • the clear inner lens 18 is carried by a pair of arms 68 the arm 68 at the left hand with a circular opening 72 surrounding the shaft 38 of the assembly 16 so that the clear visor is supported on the shaft but may move pivotally relative thereto.
  • the tinted outer visor carries at its ends respective arms 74 the right-hand one of which has a circular opening 76 surrounding the shaft 38 of the assembly 14 to permit this to pivot relative to the shaft.
  • the other arm 74 of the tinted lens 20 has a noncircular opening 78 surrounding the shaft 38 of assembly 16 so that as this shaft 38 turns the tinted lens moves with the shaft.
  • a dual visor assembly for a helmet including in combination a first shaft, a second shaft, means mounting said shafts on said helmet for movement around an axis, a first visor, means mounting said first visor on one of said shafts for rotation therewith, means mounting said first visor on the other shaft for rotation relative thereto, a second visor, means mounting said second visor on said other shaft for rotation therewith, and means mounting said second visor on said one shaft for rotation relative thereto.
  • An assembly as in claim 4 including means for releasably locking said shafts in the extended positions of said visors.
  • An assembly as in claim 5 including means for releasably locking said shafts in a position intermediate the retracted and extended positions of said visors.
  • a dual visor assembly as in claim 1 in which each of said visors is adapted to move between a retracted position and an extended position, said assembly including means for releasably positively locking each of said visors in each of its extended and retracted positions.
  • mounting means comprises respective shafts, means mounting and in which said releasable locking means comprises interengageable means on said shafts and on said shaft mounting means and means biasing said interengageable means into engagement.
  • said interengageable means comprise a pushbutton carried by said shaft for axial movement relative thereto, a boss carried by said pushbutton, means forming angularly spaced boss-receiving recesses in said shaft support, said boss being adapted to engage in one of said recesses in one axial position of said pushbutton and one rotary position of said shaft and adapted to engage in the other recess in said one axial position of said pushbutton and in another rotary position of said shaft.
  • a visor assembly for a helmet including in combination, a visor, means mounting said visor for pivotal movement between an extended position and a retracted position, said mounting means comprising a shaft, a support carrying said shaft for rotary movement, means coupling said visor to said shaft for rotary movement therewith, a pushbutton carried by said shaft for rotation therewith and for axial movement relative thereto, a lug carried by said pushbutton, means forming angularly spaced recesses in said support, said lug adapted to engage in one of said recesses in one axial position of said pushbutton and one rotary position of said shaft releasably positively to lock said visor in its extended position and adapted to engage in the other recess in said one axial position of said pushbutton and another rotary position of said shaft releasably positively to lock said visor in its retracted position, and means biasing said pushbutton toward said one axial position.
