Definitions

  • This replacement lens cartridge is mostly directed to protective face and eyewear such as is worn in the shipyard industry, but could be suitable for different types of construction sites where sandblasting/shot blasting is performed.
  • the permanent lens of the above-described respirator is protected by a disposable lens pack in a cartridge that provides 2 to 4 layers of protection depending on the lens thickness.
  • foam that surrounds the lenses in the cartridge.
  • This cartridge is inserted in a square frame on the face mask of the respirator and secured in place by a door mounted on a hinge.
  • the disposable lens are made of glass, tempered or untempered, and can be laminated for heavy blasting. As the grit rebound wears the disposable lens, they are removed from the cartridge by pulling glued tab (two on each lens). Because the lenses are made of glass, the cartridge adds a lot of weight in front of the respirator and workers have complaint about the front heaviness of the respirator. This could result in neck pain.
  • a replaceable lens cartridge for use with a face mask.
  • the cartridge includes a plurality of molded lenses, each lens sized to extend over both eyes of a wearer and having a curved shape and a plurality of catches; and a molded carrier mounting the lenses in stacked arrangement, the carrier having a first set of catches receiving the catches on one of the lenses.
  • the carrier has a second set of catches receiving the catches of the other of the lenses, the first set of catches having locations on the carrier that differ from locations of the second set of catches on the carrier.
  • the lens cartridge further includes a third molded lens sized to extend over both eyes of a wearer and having a curved shape and a plurality of catches.
  • the carrier mounts the third lens in stacked relation with the other two lenses and has a third set of catches receiving the catches of the third molded lens, the third set of catches having locations on the carrier that differ from the locations of the first and second set of catches on the carrier.
  • the plurality of catches on each lens are located along a perimeter of the lens, with the catches of each lens being spaced along the perimeter from the catches of the other lens with the lenses mounted in stacked arrangement on the carrier.
  • the plurality of catches on each lens comprises at least four projections extending from the perimeter of the lens, and the first and second set of catches on the carrier includes a matching number of reliefs on the carrier, each relief receiving one of the projections.
  • the curved shape of each of the lenses differs from one lens to the next to compensate for optical distortions produced by the lenses mounted in stacked arrangement on the carrier.
  • the lens cartridge further includes a plurality of pull tabs, each tab corresponding to one of the lenses, centered on the lens to overlie a nose bridge of the lens and attached to the lens to allow removal of the lens from the carrier when the tab is pulled by a wearer.
  • each of the lenses includes a recess underlying the pull tab to receive the pull tab and prevent unwanted interference between the pull tab and any adjacent lens.
  • the carrier further includes a fixed lens underlying the lenses mounted in stacked arrangement on the carrier, the fixed lens having a curved shape.
  • the carrier further includes a peripheral lip that extends over perimeters of the lenses mounted in stacked arrangement on the carrier.
  • the first set of catches is formed in the peripheral lip.
  • the carrier has a second set of catches formed in the peripheral lip and receiving the catches of the other of the lenses, the first set of catches having locations on the peripheral lip that differ from locations of the second set of catches on the peripheral lip.
  • each lens includes one of a cylindrical lens, a spherical lens, or a toric lens.

  • a replacement lens cartridge 10 is made from molded plastic (polycarbonate, TPU, acrylic, etc.), preferably suitable for optic purposes. Because of the process and material, the cartridge 10 offers a cost effective system compared to conventional products. Furthermore, the density of resins, such as polycarbonate, is half of the glass density which brings down the weight considerably in comparison to conventional products.
  • the cartridge 10 is provided for use on a face mask of a respirator or other device having a permanent lens for protecting the eyes of a user, such as the face mask 12 of the respirator 14 shown in Fig. 2.
  • the cartridge 10 comprises a carrier 20 and multiple (3 or 4) disposable lenses 22.
  • the cartridge 10 is preferably molded and is not limited to flat surfaces. Accordingly, each lens 22 can have a curved shape and, for example, can be a cylindrical lens, a spherical lens, or a toric lens. With those curvatures it's possible to offer more peripheral view.
  • each lens 22 inside the carrier 20 is identical. However, if overwhelming distortion occurs by stacking the lenses 22, it would be possible to make each lens 22 slightly different to correct distortion made by the previous lens 22 in the cartridge 10.
  • the carrier 20 holds the stack of lenses 22 together and provides means to attach the cartridge 10 on the respirator 14. It's also the last layer of protection of the cartridge 10 with a fixed lens 33.
  • the carrier 20 has a top tooth 34 that can be inserted into a face mask clamp or slot 36 on the face mask 12 of the respirator 14. Aligned with this top tooth 34, there is a catch in the form of a slot 38 on the carrier 20 to receive a catch in the form of a lens top tooth 40 on the first loaded lens 22.
  • the carrier 20 includes a bridge 46 that extends over the nose of a wearer and has a blade or tab 48 that has a set of catches in the form of openings 50 to receive a catch in the form of a bottom tooth 52 of each of the lenses 22.
  • This blade 48 is cantilevered from the bridge 46 and will bend when each of the lenses 22 are inserted into the carrier 10, then move to its initial or as-molded position to secure the lenses 22 in place.
  • peripheral lip 56 that extends forward to protect the lens 22 from dust that could enter between each of the lenses 22. This peripheral lip 56 also helps to avoid lens shifting.
  • each lens 22 in the cartridge 10 has a transparent pull tab 58 centered on the lens 22 to overlie a nose bridge portion 59 of the lens 22 and attached to the lens 22 for removal of the used lens 22.
  • This tab 58 could be over molded in the lens 22 or glued in a secondary operation.
  • each lens 22 has a top tooth 40 and a bottom tooth 52.
  • the top tooth 40 is made to align the first lens 22 in the carrier top slot 38.
  • the bottom tooth 52 on each lens 22 will snap into the blade 48 of the carrier bridge portion 46, with each lens 22 having its own opening 50 in the blade 48.
  • the bottom tooth 52 will break when the tab 58 is pulled.
  • another option is that a portion of the blade 48 on the bridge 46 breaks instead of the lens bottom tooth 52.
  • Figs. 21 and 22 illustrate an alternate embodiment of the cartridge 10 wherein the carrier 20 has an L-shaped cross-section with a lip 70 that extends forwardly and includes a number of tab receiving openings 72 that receive mount tabs 74 formed on each of the lenses 22.
  • This mount structure replaces the teeth 34, 40 and 52, slots 38 and 64, openings 50, blade 48, and bridge 46 of the embodiment illustrated in Figs. 1-20.
  • This embodiment also differs from the previously described embodiment in that the pull tab 58 is attached to and extends in cantilevered fashion from an upper portion of each lens 22, rather than from a lower central portion as in Figs. 1-20.
  • Figs. 23A-33 illustrate another embodiment for the lenses 22 and lens cartridge 10 together with a respirator 14 for that embodiment, with like reference numbers indicating similar features and/or components.
  • the embodiment of Figs. 23A-33 is mostly dedicated to the shipyard industry, but could be suitable for different types of construction site where sandblasting/shot blasting is performed, and could also be extended to other industries such as welding, painting, oil rig and any other activities that require optic protection that gets damaged by different media (dirt, oil, paint, etc).
  • the concept is to make the replacement lens cartridge 10 with molded plastic (polycarbonate, TPU, acrylic, etc) suitable for optic purposes. Because of the process and material, this concept is also a cost effective system. Density of resins, such as polycarbonate, is half of the glass density which brings down the weight considerably.
  • Figs. 23A-33 differs from the embodiment of Figs. 1 -20 in that it has eliminated the cantilevered blade 48 and openings 50 on the carrier 20, the corresponding tooth 52 on each of the lenses 22, the top tooth 40 on each of the lenses 22 and the corresponding slot 64 on each of the lenses 22 and has provided for a different means of releasably securing each of the lenses 22 to the carrier 20, as will be discussed more fully below.
  • the cartridge 10 comprises a carrier 20 and multiple disposable lenses 22 (3 or 4). Because the cartridge 10 is molded, the lenses 22 are no longer limited by flat surfaces, and are cylindrical lens, spherical lens or toric lens. With those curvatures it's possible to offer more peripheral view.
  • each lens inside the carrier 20 can be identical, if overwhelming distortion occurs by stacking the lenses 22 it would be possible to make each of them slightly different to correct distortion made by the previous lens 22 in the cartridge 10. More specifically, as best seen in Fig. 30, the fixed lens 33 of the carrier 20 and each of the replacement or disposable lens 22 (1 , 2 and 3) has its own inside and outside spherical radius to correct distortion/deformation that was created by the previous one.
  • Each replacement lens 22 is different in size and has different positions for a plurality of catches in the form of retaining hooks, tabs, or projections 100 formed on the perimeter of each lens 22 that clip into a corresponding set of catches in the form of recesses, openings, or grooves 1 10 formed into the peripheral lip 56 of the carrier 20. This will ensure that replacement lenses 22 are in the right order in the carrier 20 to provide optimal optics. The goal is to obtain almost no distortion with multiple layers of lenses 22.
  • the carrier 20 holds the stack of lenses 22 together and provides means to attach the cartridge 10 on the respirator 14. Its lens 33 is also the last layer of protection of the cartridge 10. As best seen in Figs. 32A-32C, the carrier 20 has a top tooth 34 that is inserted into a clamp or slot 36 in the rim 102 on the respirator 14. There is a catch in the form of a projection or hook 42 on each side of the carrier 20 to secure the lens cartridge 10 on the respirator 14 by snap engagement with catches in the form indents or recesses 44 on the face mask 12. As previously discussed, each replacement lens 22 is retained by the catches 100 on its perimeter that are inserted in the corresponding carrier catches 110.
  • Each lens 22 in the cartridge 10 has a transparent or opaque pull tab 58 in the center for removal of the used lens 22. As best seen in Figs. 30 and 33, this tab 58 can be snapped in a secondary operation by inserting each tab 58 through a slot 112 in the corresponding lens 22 until a thickened end 114 of the tab 58 is received in an indent 1 16 on the back face of the lens 22. There is a recess 60 on the front surface of the lens 20 to receive the folded tab 58 to avoid creating any unwanted gaps between the lenses 22.
