Definitions

  • the present invention relates to rimless eyeglasses hav ⁇ ing means for securing both the temple hinge elements and the nose bridge element directly to the lenses. More specifi ⁇ cally, the invention relates to such eye glasses in which at least some of said elements comprise round wire portions for connection with the lenses or glasses. In order to hold such elements the glasses should be provided with holes, but with simple, round holes it is not easy to achieve a fixation of the round wire in such a manner that the connected element cannot rotate relatively to the glass.
  • a non-rotatable connection may be obtained by forming a bent loop on the wire end and inserting the loop into an oblong hole in the glass, but this solution is not ideal because the oblong hole has to be formed with a high degree of precision in order to hold the loops properly, i.e. safely and without the glass being subjected to unacceptable stress.
  • a much better approach is to avoid the said edge kerbs and instead provide for the wire connection to or from the said eyelet to extend through a groove provided in the front or rear surface of the respec ⁇ tive glasses, without these grooves giving rise to exterior edge kerbs in the glasses.
  • the wire in or- der to prevent rotation of the associated element it is fully sufficient to make use of a surface groove in the front or rear glass side, without relying on any through-going edge kerb, only provided the eyelet is held firmly against the re ⁇ spective front or rear side of the glass in order to stabi- lise the engagement between the wire/wires and the groove/- grooves.
  • the groove or depression could be made such that it could receive even the eyelet itself, whereby the wire connection could extend in parallel with the local plane of the glass out though the groove to the generally unbroken edge of the glass.
  • this would imply a reduced thick ⁇ ness of the glass just where the hole is located, and that would normally not be desirable.
  • the wire or wires can still extend through suitable groove means, viz. when the latter extend in an inclined manner between the vi ⁇ cinity of the hole and the nearby edge of the glass. What really matters is the engagement between the wire or wires and the sides of the outermost, deeper groove end portion.
  • the invention is not limited to any particular manner of securing the wire to the hole, but a preferred arrangement is to make use of the said eyelet in association with an already known securing system comprising a threaded hole and a plas ⁇ tic bolt co-operating directly with the threads of the hole; a small bolt head may then press the eyelet firmly against the surface of the glass.
  • Fig. 1 is a perspective view of a pair of glasses made in accordance with the invention
  • Fig. 2 and 3 are perspective exploded views of details thereof, Fig. 4 is a plan sectional side view along the line IV-IV of Fig. 3. ;
  • Fig. 5 is a perspective view relating to a modified em ⁇ bodiment of the invention.
  • Fig. 6 is a sectional view, seen from above, for further illustrating the invention.
  • the glasses shown in Fig. 1 are, generally, rather simi ⁇ lar to those disclosed in WO#. They comprise two lenses 2 which are interconnected by a nose bridge element 4 secured to the lenses in points 6 in a non-rotatable manner, and at their outer sides correspondingly point connected with fixed hinge parts 8 forming hinges for respective temples 10.
  • the details 4 and 8 are made of a wire material, prefer ⁇ ably of a titanium alloy, and basically, therefore, the rele- vant connections can be established by means of a wire eyelet 12 or 14 as shown in Figs. 2 and 5 with associated two wires or one wire 16, respectively, and an associated hole 18 in the lens and a bolt 20 with bolt head 22 for clamping the eyelet against the front or rear lense side.
  • the bolt 20,22 is fixable preferably by the hole 18 being threaded, but al ⁇ ternatively by means of a nut 24 on the opposite side of the lens, as shown in dotted lines in Fig. 2.
  • connecting wire or wires 16 could be anchored against rotation about the center of the respective eyelets 12 and 14 in being bent so as to pass through a notch in the nearby outer edge of the lens, but such an arrangement would weaken the lens noticeably.
  • the notches 26, whether adapted for one or two connector wires be worked out so as to extend in an inclined manner from the full lens thickness around the hole 18 to a reduced thickness at the nearby edge of the lens, still without breaking through the lens edge as a whole.
  • the invention also deals with another problem, viz. that of arranging for stop means for the temples 10 against being swung outwardly further than to a position generally perpen ⁇ dicular to the common plane of the lenses 2.
  • the hinge portions between the parts 8 and 10 will comprise a screw wound portion of one of these elements. adapted so as to be rotatable about a straight hinge pin por ⁇ tion of the opposite element.
  • the said stop exten ⁇ sion beyond the hinge axis is a closed wire loop, which for one thing forms an overall "soft" protrusion that will not incur any tearing risks, and which for another thing is so designable that it may serve to make its own free wire end non-exposed, in that the free wire end, whether or not con ⁇ stituting the hinge pin, can be located so as to be covered by the wire extending into the loop.
  • the active stop portion of the loop will be its outermost closed end portion that will cooperate with the other hinge part outside the peri ⁇ phery of the hinge coil, i.e. well and safely spaced from the hinge pin itself, and the loop can be arranged so as to cover not only its own free wire end, but even that of the hinge pin, should these be different.
  • Fig. 7 shows a hinge similar to those used in Fig. 1.
  • the connector wires 16 from the eyelet 12 are extended so as to form a wire coil 30 or rather two superimposed, narrow eye ⁇ lets.
  • the associated temple 10 is shaped so as to have its free end portion located as a hinge pin inside the coil 30, projecting out of the lower end thereof and bent forwardly in a portion 32, upwardly in a portion 34 and rearwardly in an upper portion 36 that extends tightly above the upper end of the coil 30, thus steadily covering the area where the free end of the said hinge pin is located.
  • the rotation stop will be located with some spacing from the hinge pin, whereby the tolerance requirements are moderate for an accurately located stop.
  • fig. 8 is shown a similar system, in which the loop section 32,34,36 is turned upside down compared with Fig. 2.
  • the coil or double eyelet 30 is formed as end por ⁇ tions of rim wires 38 for a lens; for this aspect of the in ⁇ vention it is without relevance in which manner the hinge parts are fixed to the glasses.
  • Fig. 9 shows a system corresponding to Fig. 7, yet with a base structure according to Fig. 5.
  • Fig. 10 is shown an •inverted' system, where the hinge pin is formed on the connector wire 16 and the latter forms a rearwardly projecting loop cooperating directly with the foremost part of the temple, this part continuing in a real hinge coil.
  • the hinge pin portions are not received di ⁇ rectly in the coils or eyelets, but in a central plastic bushing which will provide for a suitable resistance against the pivoting movement of the temple.

Abstract

Dans les lunettes à verres nus, il faut fixer les éléments de monture directement sur les verres, en pratiquant de préférence une seule ouverture ronde (18) sur le côté de chaque verre (2). Il faut ensuite stabiliser les éléments de monture, qui se terminent habituellement par une boucle métallique ou un ÷illet (12, 14), pour les empêcher de pivoter autour de la broche de support ou de la vis correspondante en engageant le fil métallique de l'élément de monture (16) dans une entaille pratiquée sur le bord du verre. Une telle entaille, néanmoins, affaiblit le verre. C'est la raison pour laquelle, dans la présente invention, l'entaille est remplacée par une rainure (26) pratiquée à la surface du verre entre le trou (18) et le bord du verre, ce qui permet de na pas casser le contour extérieur du verre tout en conférant une stabilité optimale à la boucle métallique de l'élément de monture (16).
