Definitions

  • the present invention regards goggles with interchangeable lens, particularly adapted for use in undertaking sporting activities, such as skiing, snowboarding and the like.
  • the photochromatic lenses contain photosensitive pigments, having the property of reversibly modifying their own chromatic range as a function of the intensity of the environmental light hitting thereon. In other words, with the increase of the environmental light intensity, the photochromatic lenses absorb a greater quantity of light radiation, becoming darker, while when the light intensity decreases, they return to the clear state.
  • photochromatic lenses have had a hard time being applied in sporting settings and particularly in skiing.
  • visibility can vary in a sudden manner, passing from extremely sunny conditions, which require the use of dark lenses adapted to protect a user's eyes from the sun rays and to allow a clear vision of the pistes, to cloudy conditions, that require the use of clearer lenses, which accentuate the contrasts on the white background.
  • Photochromatic lenses are incapable of quickly adapting themselves to these environmental condition changes, and thus piste visibility changes, with obvious problems for the skier.
  • the pigments present on the lenses are mainly activated by light with wavelength in the range of the blue band (430-490 nm) , which is not filtered by clouds at high elevation, so that the photochromatic lenses remain dark even in the presence of a cloudy sky and thus reduced visibility conditions, with a clearly negative impact on the user's vision.
  • the lenses are subject to damage, for example breaking, and more frequently scratches, and must therefore be substituted.
  • Such lens substitution systems are of various type, and include magnetic systems, systems for extracting lenses through a slit made on the frame and subsequent insertion through the same slit of a different colour lens, and systems that provide for the opening of a front portion of the frame and substitution of the existing lens with a new one.
  • the goggles with interchangeable lenses known at the state of the art are not very practical, particularly on the ski pistes where it is desirable to be able to quickly substitute the lenses and advantageously while not removing the mask. Moreover, these goggles have the drawback that the lenses fog up.
  • moisture is generated in the space typically present between the user's face and the lens. Due to the difference of temperature between such space and the outside environment, the moisture condenses on the internal surface of the lens with consequent fogging up of the same .
  • double-glass lenses composed of two lenses that are appropriately spaced so to form a gap, which is hermetically sealed from the outside environment by means of a rubber seal so to maintain a constant temperature within the gap.
  • double-glass lenses are, however, costly and do not lend themselves well to being used in interchangeable lens goggles.
  • the main object of the present invention is to eliminate, or at least reduce, the above-lamented drawbacks by providing goggles with interchangeable lens in which the lens can be quickly and immediately substituted, even while keeping the goggles on.
  • Another object of the present invention is that of providing a goggles with interchangeable lens that has anti-fogging performances comparable with those of the goggles that mount fixed double-pane lenses .
  • the main effect of the present invention is therefore that of maintaining the advantageous performances of the double lenses, i.e. substantial elimination of the fogging, and at the same time carrying out a quick and simple substitution of a single lens, even while keeping the goggles on.
  • Figure 1 is a front view of a goggles with interchangeable lenses according to the present invention
  • Figure 2 is a perspective view of the mask of Figure 1;
  • Figure 3 is an exploded perspective view of the goggles of Figure 1 in open position for the substitution of a lens
  • Figure 4 is a perspective view of an alternative embodiment of a removable lens.
  • a goggles produced according to the present invention is formed by a frame 12 comprising a rear or inner portion 20, i.e. that turned, in use, towards the user's face, and a front or outer portion 30, between which a lens 40 is interposed during use.
  • the lens 40 is a double lens, i.e. comprising a first lens 42 and a second lens 44.
  • the frame 12 is made of any suitable material, preferably thermoplastic or thermosetting polymer materials or composite materials.
  • the inner portion 20 comprises a seal element 22, typically made of a soft material, for example rubber, or of a spongy material, which extends along its entire perimeter. In use, the seal element 22 is in contact with the face of a user and allows a correct positioning of the mask 10, at the same time preventing the entrance of external agents, typically snow, in the space that is created between the user's face and the frame 12.
  • the inner portion 20 moreover comprises a perimeter edge 24, that has, for its entire extension, a groove-shaped seat 26, designed to permanently house the perimeter edge of the first lens 42 of the double lens 40, to which reference will be made below with the term "fixed lens".
  • Such fixed lens 42 is a clear or neutral lens, typically made of any suitable material, for example polycarbonate, cellulose propionate, cellulose acetate and similar materials .
  • the fixed lens 42 can be subjected to suitable anti-fogging treatments known in the art, so to further increase the anti- fogging performances of the goggles.
  • centring elements are formed for the second lens 44, to which reference is made below with the term "removable lens".
  • the centring elements consist of a lower tooth 23a formed at the nosepiece portion 14 of the goggles 10 and an upper tooth 23b, central with respect to the upper edge of the goggles 10.
  • the lower and upper teeth, 23a and 23b are destined to be engaged with respective seats 43a and 43b obtained by means of notches along the edge of the removable lens 44.
  • the teeth 23a and 23b are, moreover, placed at a predetermined distance from the housing groove 26 of the fixed lens 42, such that, in use, a sealed gap is formed between the fixed lens 42 and the removable lens 44, sealed along its entire perimeter by sealing means, for example a rubber seal 46.
  • the sealing of the gap allows preventing the fogging up, respectively of the outer surface of the fixed lens 42 and the inner surface of the removable lens 44, with obvious advantages in terms of user visibility.
  • the removable lens 44 is also made of polycarbonate, cellulose propionate or cellulose acetate and it is clear, neutral or coloured, the colour being chosen by the user as a function of the lighting conditions of the use environment, such as for example the visibility present on a ski piste.
  • the removable lens 44 can be subjected to suitable treatments known in the art, for example anti-scratch treatments and the like.
  • suitable treatments for example anti-scratch treatments and the like.
  • the removable lens 44 can bear more than two seats 43, uniformly distributed along its entire edge. In such case, a corresponding number of centring teeth 23 will be provided for on the peripheral edge 24 of the inner portion 20.
  • one or more aeration openings 27 are provided, adapted to permit the entrance of air inside the space present between the fixed lens 42 and the user's face and having the function of preventing the formation of condensate on the lens surfaces .
  • Aeration openings can also be provided on a lower portion of the edge 24.
  • the outer portion 30 consists of a shaped element that delimits an opening 32 substantially corresponding to the shape of the removable lens 42. It is connected to the internal portion 20 through articulation means of known type.
  • such articulation means comprises a pair of hinges 36 placed at the lower edges of the inner 20 and outer 30 portions and in a symmetrical position with respect to the nosepiece 14 of the goggles 10.
  • the pair of hinges 36 allows an articulated movement, with respect to the inner portion 20, of the outer portion 30 of the frame 12, between a closed position of the goggles 10, in which the outer portion 30 is superimposed on the inner portion, and an open position of the goggles 10, in which the outer portion 30 is moved away from the inner portion 20, thereby permitting access to the goggles 10 interior.
  • the outer portion 30 has coupling means, in the embodiment illustrated in the figures two lateral hooks or clips 38 and an upper central hook or clip 39, destined in use to be coupled with releasable snap-engagement with corresponding lateral inserts 28 and a corresponding upper central insert 29 formed in the inner portion 20.
  • both the clips 38 and 39 and the respective inserts 28 and 29 are made of semi-rigid material.
  • the mask 10 is completed with positioning means with respect to the user's head, such as for example an adjustable and removable elastic band having both ends fixed with a respective engagement means to the two opposite ends of the inner portion 20.
  • each engagement means is composed of a claw-shaped element 33, which comprises a main body 35 pivoted to the inner portion 20 and a spring element 37 inserted in the main body 35.
  • a claw-shaped element 33 which comprises a main body 35 pivoted to the inner portion 20 and a spring element 37 inserted in the main body 35.
  • the user can release the removable lens 44 from the lower and upper teeth 23a and 23b and extract it from the inner portion 20, after which the user can insert a new removable lens 44 in the goggles 10, for example a different colour lens, locking it in position by means of engagement of the seats 43a and 43b in the respective lower and upper teeth 23a and 23b.
