  • This invention relates to eyewear.
  • this invention relates to eyewear defined by a planar body of unitary construction and a method of making an eyewear cut-out.
  • Eyewear refers to articles which are worn either on or over the eyes. Eyewear may serve one or more purposes for the wearer, including correcting optical deficiencies, protecting the eyes from damage or purely for fashion purposes. Protecting the wearer's eyes forms the most utilitarian purpose of eyewear and such utilitarian eyewear broadly includes safety goggles. Safety goggles shield the eyes and surrounding areas from harmful particles and/or exposure, particularly in working environments.
  • eyewear defined by a planar body of unitary construction, which is characterized by at least one optical element and two ear engagement arms extending outwardly from lateral sides of the at least one optical element, the at least one optical element being shaped to extend over eyes of a wearer in use.
  • the ear engagement arms may be coplanar with the planar body, the planar body being foldable to form wearable eyewear.
  • the planar body may be provided with a notch to accommodate a nasal bridge of the wearer.
  • the planar body may be foldable about two vertices to define two cones proximate outer sides of the planar body such that the at least one optical element extends in one plane along the slants defined about the vertices and the two ear engagement arms extend along the slants opposed to the optical element slants at an angle of approximately 90° to the plane of the at least one optical element.
  • the one plane may extend across the wearer's eyes
  • the two ear engagement arms may extend along the sides of the wearer's head

  • the planar body may include at least two connection points to retain the sides of the two cones in position.
  • the at least two connection points may be the form of any one of a slit-joint, a button joint, a press stud, an adhesive joint or the like.
  • the at least two connection points may include a first set of connection points and a second set of connection points, the first set of connection points being positioned on a lower portion of the at least one optical element and the second set of connection points being positioned at an inner portion of the two ear engagement arms.
  • the first set of connection points may receive the second set of connection points in use, such that the planar body is folded about the two vertices to define the two cones, forming wearable eyewear.
  • the planar body may be foldable along two parallel fold lines at the outer sides of the at least one optical element such that the two ear engagement arms extend rearwardly at approximately right angles to the at least one optical element.
  • the two parallel fold lines may form a hinge in use, the hinge separating the at least one optical element from the two ear engagement arms and allowing movement of the ear engagement arms in relation to the at least one optical element.
  • the at least one optical element may remain substantially planar in use.
  • the planar body may include at least one nose rest on an inside edge of the notch, the at least one nose rest being of unitary construction with the planar body.

  • the vision correction lenses may include any one of concave lenses, convex lenses or combinations thereof to define bifocal, multifocal, progressive lenses or the like.
  • the at least one optical element may be formed by injection moulding, or the like.
  • the protective lenses may include any one or more of filtered lenses, photochromic lenses or the like.
  • the filtered lenses may include any one or more of colour filters, polarization filters or the like.
  • the planar body or a part thereof may include any one or more coatings, the coatings including any of ultra-violet (UV) protective coating, an infrared (IR) protective coating, an anti-reflective coating, a scratch-resistant coating, an anti-fogging coating and a water-shedding coating or the like.
  • the planar body may be manufactured from a flexible and transparent material, the flexible and transparent material being rigid or semi-rigid.

  • Figure 1 shows a plan view of eyewear in accordance with a first aspect of the invention
  • Figure 2 shows the eyewear of Figure 1 illustrating a vertex
  • Figure 3 shows the eyewear of Figure 1 in use
  • Figure 4 shows eyewear in accordance with another embodiment of the invention.
  • reference numeral (100) refers to eyewear defined by a planar body of unitary construction.
  • the planar body (100) defines two optical elements (102) and two ear engagement arms (104) which extend outwardly from lateral sides of the optical elements (102), the ear engagement arms (104) remaining coplanar with the planar body (100).
  • the planar body (100) is foldable to form wearable eyewear in use, however it does not define a separate frame, hinge or lenses. Instead, the two optical elements (102) are shaped and dimensioned to extend over eyes of a wearer and the two ear engagement arms (104) support the optical elements (102) on ears of the wearer.
  • the planar body (100) is provided with a notch (106) to accommodate a nasal bridge of the wearer.
  • the notch (106) links the two optical elements (102) at an operatively central position of the planar body (100).
  • the notch (106) is defined by an hourglass shape, with a bottom edge of the notch (106) being more concave in comparison to a top edge of the notch (106). This hourglass shape of the notch (106) brings a contour of the planar body (100) which broadly fits a brow shape of the wearer in use.
  • the planar body (100) is foldable about two vertices (108) to define two cones proximate outer sides of the planar body (100), such that the two optical elements (102) extend in one plane along the slants defined about the vertices (108) and the two ear engagement arms (104) extend along the slants opposed to the optical element slants at an angle of approximately 90° to the plane of the optical elements (102).

  • one other fold line (110) is provided in the planar body (100) and is positioned within the notch (106). In transporting, the one other fold line (110) is folded such that operatively inner sides of the optical elements (102) are brought together to reduce an overall size of the planar body (100) for compact packaging.
  • the two ear engagement arms (104) are defined by an upper edge (104.2) and a lower edge (104.4).

  • the lower edge (102.4) of the ear engagement arms define a V-shaped cut (112) at the point of extending outwardly and backwardly from the lateral sides of the optical elements (102). As best shown in Figure 3, the V-shaped cut (1 12) enables the folding about the two vertices (108) to define the two cones.
  • the lower edge (104.4) of the two ear engagement formations is adapted to hold the optical elements (102) over the wearer's eye and eye area.
  • the ear engagement formations (104) engage with the wearer's ear at an outer portion of each ear engagement formation (104).
  • the lower edge (104.4) of the outer portion has a curvature to receive the wearer's ear is use.
  • the planar body (100) includes at least one connection point (200).
  • the planar body (100) includes two connection points (200), each of which is in the form of a slit-joint.

  • the first connection point (200.2) receives the second connection point (200.4) in use, such that the planar body (100) is folded about the two vertices (108) to define the two cones, forming wearable eyewear.
  • Figure 4 shows another embodiment of the eyewear (100), in which the planar body (100) includes two nose rests (300) on an inside edge of the notch (106).
  • the nose rests (300) are of unitary construction with the planar body (100) and in use, the nose rests (300) rest on an upper nose portion of the wearer, holding the planar body (100) over the wearer's eyes and eye area.
  • the optical elements (102) are formed to define protective lenses.
  • the protective lenses can be from a filter material to reduce glare or to enhance contrast depending on the particular application for which the eyewear is to be used.
  • the planar body (100) is manufactured from a flexible and transparent material which is semi-rigid. Specifically, the planar body (100) is manufactured by die cutting and is in the form of a cut-out. The cut-out formation allows the planar body (100) to be stacked for effective transportation.

Les lunettes sont définies par un corps plan de structure unitaire. Le corps plan définit au moins un élément optique et deux branches d'accrochage avec les oreilles qui s'étendent vers l'extérieur à partir des côtés latéraux du au moins un élément optique. Le au moins un élément optique est façonné de manière à s'étendre, en utilisation, au-dessus des yeux d'un utilisateur.
