Definitions

  • the invention relates to a spectacles additional disc with fastening means.
  • a spectacles additional disc is arranged either on the side facing away from the wearer of the spectacle wearer or on the spectacle wearer facing side of the spectacles.
  • These eyeglass pads extend over the lens and various suggestions are made as to how the eyeglass additional lens can be adapted to the bending of the lens.
  • the invention is therefore based on the object to further develop eyewear additional discs with fasteners so that they are cheaper to produce.
  • the same material can be used as the disc material for the additional spectacle discs as for the attachment means. Therefore, it is further proposed that the fastening means are formed of the same material as the additional spectacle lenses.
  • the eyewear extra discs are usually made of a flexible material and this makes it possible through a suitable shaping the fasteners and the eyeglass additional discs in one piece.
  • an additional spectacle disc with fastening means can be cut out of a flat sheet of material.
  • the attachment means with the additional spectacles disc lie in a plane, the shaping allows a bending of the attachment means from the plane of the additional spectacle disc and thereby the hook-like attachment of the spectacles additional disc to a spectacle frame.
  • the eyeglass additional disc can thereby easily by bending on either side facing the wearer the fastening means are fastened or on the side facing away from the wearer.
  • the extra spectacles washer can be designed such that a spectacles additional disc covers both spectacle lenses. It is advantageous, however, if the additional spectacle lens is designed such that it covers only one spectacle lens. As a result, a spectacles additional disc can be easily applied to the inner or the outer sides of the spectacle lens and fastened with the fastening means.
  • the fastening means are hook-shaped.
  • Such hook-shaped fastening means can be pressed over the edge of the spectacle lens or the spectacle frame, so that the nose of the hook detent comes to rest on the side of the spectacle frame or the spectacle lens opposite the spectacle accessory disc.
  • the attachment means thus clamped between spectacles additional disc and the nose of the hook, the glasses or the spectacle lens.
  • the fastening means have a web leading away from the disc web, a carrier and a hook nose, which are arranged in a U-shape.
  • Such a substantially U-shaped hook allows to be flexibly bent and latching the eyewear additional disc to the glasses or to attach the spectacle lens.
  • a particularly advantageous embodiment variant provides that the material width decreases from the bridge over the carrier to the hook nose.
  • the fastening means in the vicinity of the additional spectacle washer has a particular stability, which decreases in the direction of the hook nose. A bending force exerted on the fastening means will thus deform the fastening means, above all in the region of the carrier and less in the area of the web.
  • the hook nose can be made very small.
  • the hook nose arranged on the side of the spectacles opposite the window can thus be designed to be particularly small and inconspicuous.
  • opposite hook noses are arranged on the same side of the web.
  • the carriers and the hooked tabs arranged thereon extend in the same direction from the point of attachment of the web to the additional spectacles washer. This makes it easier to handle the additional spectacle lens when attaching the additional spectacle disc to a pair of spectacles or spectacle lenses.
  • the spectacle additional discs described clamp the spectacle lens to the spectacles or spectacle lens via a force acting perpendicular to the additional spectacle slice. As a result, the frame of the spectacles or the spectacle lens itself is clamped with a force extending perpendicularly to the plane of the extra spectacle disc.
  • the attachment means on the additional spectacle disc may also be designed so that it is clamped cumulatively or alternatively the additional spectacle disc with a force acting in the plane of the additional spectacle washer force.
  • a set of additional eyeglasses with special attachment means and a pair of glasses is proposed, in which the distance of the carrier is smaller than the corresponding distance of the opposite outer edges of the glasses. This creates a clamping force between opposing straps, which makes it possible to attach the spectacles additional disc to the spectacles or to support the attachment.
  • the eyeglass additional disc 1 shown has two attachment means 2, 3, which are arranged on opposite sides 4, 5 of the additional spectacle disc 1.
  • the extra spectacles washer is cut with a laser cutter from a flat disc of flexible but transparent material. Already the selected material allows a certain flexibility of the additional spectacles.
  • a plastic disk in particular a disk made of a polycarbonate, is suitable for this purpose.
  • the slice thickness is 0.3 to 1 mm and preferably about 0.5 mm. This results in that the hook-shaped fastening means 2, 3 can be easily bent out of the plane of the additional spectacle washer.
  • the hook-shaped fastening means 2, 3 have a web 6, 7 leading away from the disk, a carrier 8, 9 and in each case a hook nose 10, 11. In order to form the hook, the web, carrier and hook nose are arranged in a U-shape. This creates a cavity 12, 13, which is bounded by the disk, web, carrier and hook nose and can accommodate a spectacle frame.
  • the distance between the upper edge 4 of the additional spectacle washer 1 and the carrier 8 is selected to be larger or smaller.
  • the distance between the web 6, 7 and the hook nose 10, 11 is selected to be larger or smaller.
  • a uniform distance can be chosen because of different deflection of the carrier 8, 9 can be reacted to different thicknesses of a spectacle frame.
  • the distance between the carriers 8 and 9 is selected to be about 0.5 mm less than the height of the spectacle frame this place.
  • a slight bending of the carrier 8, 9 relative to the web 6, 7 in the plane of the additional spectacle additional disc is necessary to hold the additional spectacle disc on the spectacle frame.
  • the special shape of the hook-shaped fastening means 2, 3 ensures that even with a bending of the fastening means 2, 3 only the least possible torsion on the bridge 6, 7 acts on the additional spectacle disc 1.
  • the length and shape of the hook-shaped fastening means is chosen so that in a simple manner just as much bending force must act on the fastening means in the direction perpendicular to the additional spectacle washer in order to easily pull the fastening means over the spectacle frame.
  • the fastener must also not be bent too much to avoid material fatigue.
  • the coordination of the shape and material thickness as well as the choice of material must be selected such that the additional spectacles washer is securely held to the frame of the spectacles via the fastening means.
  • the fastening means should be kept as narrow as possible, so that they attract attention in a top view of the additional spectacles additional disc.
  • the hook nose 10, 11 should be designed to be particularly small, so they do not attract attention and on the other hand holds the additional spectacles additional to the glasses.
  • the length of the carrier 8, 9 is chosen so that even very thick spectacle frame and lenses up to 8 mm thickness between the web 6, 7 and the hook nose 10, 11 place.
  • the shape of the space 12 facing side of the additional spectacle disk 1 and the fastening means 2 can be chosen so that the fastening means U-shaped fits around a spectacle frame or a spectacle lens. However, it is advantageous to choose a possible general shape that fits different eyeglass frames and lenses.
  • the extra spectacles washer is preferably placed on the side of the spectacles facing the spectacle wearer.
  • the additional spectacle disk 1 is cut out so that it fits approximately on the spectacle lens.
  • the thumb and forefinger pressed lightly towards the glasses on the trained as a bracket or hook fasteners so that the hook nose 10, 11 is pushed over the glasses frame or the lens.
  • the hook nose 10, 11 is first pressed radially outwards, so that it snaps back by its elasticity on the other side of the eyeglass frame or lens inward, so as to keep the extra spectacles 1 on spectacle frame or lens safe.
