Description
Brillenzusatzscheibe mit Befestigungsmitteln Additional pair of eyeglasses with fasteners
[Ol] Die Erfindung betrifft eine Brillenzusatzscheibe mit Befestigungsmitteln. [Ol] The invention relates to a spectacles additional disc with fastening means.
[02] Eine Vielzahl an unterschiedlichen Brillenzusatzscheiben ist in der WO 2008/128509 A beschrieben. Hierbei wird mit einem Kleber oder unterschiedlichen hakenartigen Befestigungsmitteln eine Brillenzusatzscheibe entweder auf der dem Brillenträger abgewandten Seite der Brille oder auf der dem Brillenträger zugewandten Seite der Brille angeordnet. Diese Brillenzusatzscheiben erstrecken sich über das Brillenglas und es werden verschiedene Vorschläge gemacht, wie die Brillenzusatzscheibe an die Biegung des Glases angepasst werden kann. [02] A variety of different eyewear additional discs is described in WO 2008/128509 A. Here, with an adhesive or different hook-like 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.
[03] Es hat sich jedoch herausgestellt, dass die vorgeschlagenen unterschiedlichen Befestigungsmittel in der Regel sehr aufwendig in der Herstellung sind und daher eine industrielle Fertigung derartiger Brillenzu- satzscheiben zu hohen Kosten führt. However, it has been found that the proposed different fastening means are usually very expensive to produce and therefore an industrial production of such spectacle lenses leads to high costs.
[04] Der Erfindung liegt daher die Aufgabe zu Grunde Brillenzusatzscheiben mit Befestigungsmitteln so weiter zu entwickeln, dass sie günstiger herstellbar sind. [04] The invention is therefore based on the object to further develop eyewear additional discs with fasteners so that they are cheaper to produce.
BESTÄTIGUNGSKOPIE [05] Diese Aufgabe wird mit Brillenzusatzscheiben mit Befestigungsmitteln gelöst, bei denen die Befestigungsmittel einstückig mit der Brillenzusatzscheibe ausgebildet sind. CONFIRMATION COPY [05] This object is achieved with eyeglass additional discs with fastening means, in which the fastening means are formed integrally with the eyeglass additional disc.
[06] Nach vielen Versuchen hat sich herausgestellt, dass als Scheibenma- terial für die Brillenzusatzscheiben das gleiche Material verwendet werden kann wie für die Befestigungsmittel. Daher wird weiterbildend vorgeschlagen, dass die Befestigungsmittel aus dem gleichen Material wie die Brillenzusatzscheiben ausgebildet sind. [06] After many tests, it has been found that 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.
[07] Die Brillenzusatzscheiben werden in der Regel aus einem flexiblen Material hergestellt und dies ermöglicht es durch eine geeignete Formgebung die Befestigungsmittel und die Brillenzusatzscheiben einstückig herzustellen. [07] 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.
[08] Insbesondere wenn die Befestigungsmittel die gleiche Dicke wie die Brillenzusatzscheibe aufweisen, kann eine Brillenzusatzscheibe mit Befes- tigungsmitteln aus einem planen Materialbogen ausgeschnitten werden. Obwohl dann die Befestigungsmittel mit der Brillenzusatzscheibe in einer Ebene liegen, erlaubt die Formgebung eine Verbiegung der Befestigungsmittel aus der Ebene der Brillenzusatzscheibe und dadurch die hakenartige Befestigung der Brillenzusatzscheibe an einem Brillengestell. [09] Die Brillenzusatzscheibe kann dadurch auf einfache Art und Weise entweder auf der dem Brillenträger zugewandten Seite durch Verbiegung der Befestigungsmittel befestigt werden oder auch auf der dem Brillenträger abgewandten Seite. [08] In particular, if the attachment means have the same thickness as the additional spectacle disc, an additional spectacle disc with fastening means can be cut out of a flat sheet of material. Although then 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.
[10] Die Brillenzusatzscheibe kann so ausgebildet sein, dass eine Brillenzusatzscheibe beide Brillengläser überdeckt. Vorteilhaft ist es jedoch, wenn die Brillenzusatzscheibe so ausgebildet ist, dass sie nur ein Brillenglas abdeckt. Dadurch kann auf einfache Art und Weise eine Brillenzusatzscheibe auf der inneren oder der äußeren Seiten des Brillenglases angelegt und mit den Befestigungsmitteln befestigt werden. [10] 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.
[11] Hierzu ist es vorteilhaft, wenn zwei Befestigungsmittel gegenüber- liegend an der Brillenzusatzscheibe angeordnet sind. In Ausnahmefällen kann jedoch auch ein günstig geformtes Befestigungsmittel für die Befestigung der Brillenzusatzscheibe am Brillenglas oder Brillenrahmen ausreichen. Je nach Brillenglas oder Formgebung der Brille können jedoch auch mehr als zwei Befestigungsmittel dazu dienen, die Brillenzusatzscheibe an der Brille oder dem Brillenglas zu befestigen. [11] For this purpose, it is advantageous if two fastening means are arranged opposite one another on the additional spectacles washer. In exceptional cases, however, a conveniently shaped attachment means for attaching the additional spectacle lens to the lens or spectacle frame may be sufficient. Depending on the spectacle lens or the shape of the spectacles, however, more than two attachment means can also be used to attach the extra spectacles disc to the spectacles or the spectacle lens.
[12] Eine besonders einfache Ausführungsvariante sieht vor, dass die Befestigungsmittel hakenförmig ausgebildet sind. Derartige hakenförmige Befestigungsmittel können über den Rand des Brillenglases oder des Brillenrahmens gedrückt werden, sodass die Nase des Hakens rastend auf der der Brillenzusatzscheibe gegenüber liegenden Seite des Brillenrahmens oder des Brillenglases zu liegen kommt. Das Befestigungsmittel klemmt damit zwischen Brillenzusatzscheibe und der Nase des Hakens die Brille bzw. das Brillenglas ein. [13] Hierzu wird vorgeschlagen, dass die Befestigungsmittel einen von der Scheibe wegführenden Steg, einen Träger und eine Hakennase aufweisen, die U-förmig angeordnet sind. Ein derartiger im Wesentlichen U- förmiger Haken erlaubt es, flexibel verbogen zu werden und rastend die Brillenzusatzscheibe an der Brille oder am Brillenglas zu befestigen. A particularly simple embodiment provides that 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. For this purpose, it is proposed that 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.
[14] Eine besonders vorteilhafte Ausführungs Variante sieht vor, dass die Materialbreite vom Steg über den Träger zur Hakennase abnimmt. Dadurch hat das Befestigungsmittel in der Nähe der Brillenzusatzscheibe eine besondere Stabilität, die in der Richtung zur Hakennase abnimmt. Eine auf das Befestigungsmittel ausgeübte Biegekraft wird somit das Befestigungsmittel vor allem im Bereich des Trägers und weniger im Bereich des Steges verformen. Wenn darüber hinaus die Materialbreite auch weiterhin bis zur Hakennase noch abnimmt, kann die Hakennase besonders klein ausgeführt werden. Die an der der Scheibe gegenüberliegenden Seite der Brille angeordnete Hakennase kann damit besonders klein und unauffällig ausgebildet sein. A particularly advantageous embodiment variant provides that the material width decreases from the bridge over the carrier to the hook nose. As a result, 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. In addition, if the material width continues to decrease until the hook nose, 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.
[15] In der Praxis hat sich herausgestellt, dass es vorteilhaft ist, wenn gegenüberliegende Hakennasen auf der gleichen Seite des Steges angeordnet sind. Bei einer Draufsicht auf die Brillenzusatzscheibe erstrecken sich die Träger und die daran angeordneten Hakennasen vom Punkt der Befestigung des Steges an der Brillenzusatzscheibe in die gleiche Richtung. Dies erleichtert den Umgang mit der Brillenzusatzscheibe beim Aufstecken der Brillenzusatzscheibe auf eine Brille oder ein Brillenglas. [16] Die beschriebenen Brillenzusatzscheiben klemmen die Brillenzu- satzscheibe über eine senkrecht zur Ebene der Brillenzusatzscheibe wirkende Kraft an die Brille oder ein Brillenglas. Dadurch wird der Rahmen der Brille oder das Brillenglas selber mit einer sich senkrecht zur Ebene der Brillenzusatzscheibe erstreckenden Kraft eingeklemmt. In practice, it has been found that it is advantageous if opposite hook noses are arranged on the same side of the web. In a plan view of the additional spectacle washer, 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. [16] 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.
[17] Die Befestigungsmittel an der Brillenzusatzscheibe können jedoch auch so ausgebildet sein, dass sie kumulativ oder alternativ die Brillenzusatzscheibe mit einer sich in der Ebene der Brillenzusatzscheibe wirkenden Kraft angeklemmt wird. Hierzu wird ein Set aus einer Brillenzusatzscheibe mit speziellen Befestigungsmitteln und einer Brille vorgeschlagen, bei der der Abstand der Träger kleiner ist als der entsprechende Abstand der gegenüberliegenden äußeren Ränder der Brille. Dadurch entsteht eine Spannkraft zwischen gegenüberliegenden Trägern, die es erlaubt, die Brillenzusatzscheibe an der Brille zu befestigen oder die Befestigung zu unterstüt- zen. However, 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. For this purpose, 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.
[18] Ein Ausführungsbeispiel einer erfindungsgemäßen Brillenzusatzscheibe ist in der Figur dargestellt und wird im Folgenden näher beschrieben. [18] An embodiment of a spectacles additional disc according to the invention is shown in the figure and will be described in more detail below.
[19] Die gezeigte Brillenzusatzscheibe 1 hat zwei Befestigungsmittel 2, 3, die an gegenüberliegenden Seiten 4, 5 der Brillenzusatzscheibe 1 angeordnet sind. [20] Die Brillenzusatzscheibe ist mit einer Laserschneideinrichtung aus einer planen Scheibe aus flexiblem, aber durchsichtigem Material geschnitten. Bereits das gewählte Material erlaubt eine gewisse Flexibilität der Brillenzusatzscheibe. Hierzu eignet sich beispielsweise eine Kunststoff- scheibe, wie insbesondere eine Scheibe aus einem Polycarbonat. Die Scheibendicke liegt bei 0,3 bis 1 mm und vorzugsweise bei ca. 0,5 mm. Dies führt dazu, dass die hakenförmig ausgebildeten Befestigungsmittel 2, 3 aus der Ebene der Brillenzusatzscheibe leicht herausgebogen werden können. [21] Die hakenförmigen Befestigungsmittel 2, 3 haben einen von der Scheibe wegführenden Steg 6, 7, einen Träger 8, 9 und jeweils eine Hakennase 10, 11. Zur Ausbildung des Hakens sind Steg, Träger und Hakennase U-förmig angeordnet. Dadurch entsteht ein Hohlraum 12, 13, der von Scheibe, Steg, Träger und Hakennase umgrenzt wird und einen Brillen- rahmen aufnehmen kann. 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. [20] 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. For example, 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. [21] 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.
[22] Je nach Höhe des Brillenrahmens wird der Abstand zwischen dem oberen Rand 4 der Brillenzusatzscheibe 1 und dem Träger 8 größer oder kleiner gewählt. Je nach Dicke des Brillenrahmens wird der Abstand zwischen dem Steg 6, 7 und der Hakennase 10, 11 größer oder kleiner ge- wählt. [22] Depending on the height of the 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. Depending on the thickness of the spectacle frame, the distance between the web 6, 7 and the hook nose 10, 11 is selected to be larger or smaller.
[23] Im Hinblick auf den Abstand zwischen dem Steg 6, 7 und der Hakennase 10, 11 kann ein einheitlicher Abstand gewählt werden, da durch unterschiedliche Auslenkung des Trägers 8, 9 auf unterschiedliche Dicken eines Brillenrahmens reagiert werden kann. With regard to the distance between the web 6, 7 and the hook nose 10, 11, 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.
[24] Um die Brillenzusatzscheibe zusätzlich durch eine Kraft und Klemmwirkung innerhalb der Ebene der Brillenzusatzscheibe an einer Brille zu halten, wird der Abstand zwischen den Trägern 8 und 9 so gewählt, dass er etwa 0,5 mm geringer ist als die Höhe des Brillenrahmens an dieser Stelle. Dadurch ist auch eine geringe Verbiegung des Trägers 8, 9 relativ zum Steg 6, 7 in der Ebene der Brillenzusatzscheibe notwendig, um die Brillenzusatzscheibe am Brillenrahmen zu halten. [25] Die spezielle Formgebung der hakenförmigen Befestigungsmittel 2, 3 sorgt dafür, dass auch bei einem Verbiegen der Befestigungsmittel 2, 3 nur möglichst wenig Torsion über den Steg 6, 7 auf die Brillenzusatzscheibe 1 wirkt. Die Länge und Formgebung der hakenförmigen Befestigungsmittel ist so gewählt, dass auf einfache Art und Weise gerade so viel Bie- gekraft in senkrechter Richtung zur Brillenzusatzscheibe auf das Befestigungsmittel wirken muss, um das Befestigungsmittel leicht über den Brillenrahmen zu ziehen. Das Befestigungsmittel darf aber auch nicht zu stark gebogen werden, um eine Materialermüdung zu vermeiden. [24] In order to additionally hold the additional spectacles washer by means of a force and clamping effect within the plane of the additional spectacles washer, 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. As a result, 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.
[26] Die Abstimmung von Formgebung und Materialdicke sowie Materi- alwahl ist so zu wählen, dass die Brillenzusatzscheibe über die Befestigungsmittel sicher am Rahmen einer Brille gehalten wird. Hierbei sollen die Befestigungsmittel möglichst schmal gehalten werden, damit sie bei einer Draufsicht auf die Brillenzusatzscheibe optisch wenig auffallen. Ins- besondere sollte die Hakennase 10, 11 besonders klein ausgebildet sein, damit sie nicht auffällt und andererseits aber die Brillenzusatzscheibe sicher an der Brille hält. [26] 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. Here, 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. INS In particular, 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.
[27] Die Länge des Trägers 8, 9 wird so gewählt, dass auch besonders dicke Brillenrahmen und -gläser bis 8 mm Dicke zwischen dem Steg 6, 7 und der Hakennase 10, 11 Platz finden. Die Form der zum Raum 12 weisenden Seite der Brillenzusatzscheibe 1 und des Befestigungsmittels 2 kann so gewählt werden, dass sich das Befestigungsmittel U-förmig passend um einen Brillenrahmen oder ein Brillenglas legt. Vorteilhaft ist es jedoch, eine möglicht allgemeine Form zu wählen, die zu unterschiedlichen Brillenrahmen und Brillengläsern passt. [27] 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.
[28] Bei der Verwendung der Brillenzusatzscheibe 1 wird die Brillenzusatzscheibe vorzugsweise auf der dem Brillenträger zugewandten Seite der Brille aufgelegt. Die Brillenzusatzscheibe 1 ist dabei so ausgeschnitten, dass sie etwa auf das Brillenglas passt. Anschließend wird mit Daumen und Zeigefinger leicht zur Brille hin auf die als Bügel oder Haken ausgebildeten Befestigungsmittel gedrückt, sodass die Hakennase 10, 11 über den Brillenrahmen oder das Brillenglas geschoben wird. Dabei wird die Hakennase 10, 11 zunächst radial nach außen gedrückt, sodass sie durch ihre Elastizität auf der anderen Seite des Brillenrahmens oder Brillenglases wieder nach innen schnappt, um so die Brillenzusatzscheibe 1 am Brillenrahmen oder Brillenglas sicher zu halten. [28] When using the additional spectacles washer 1, 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. Subsequently, with 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. In this case, 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.
