Definitions
- the present invention relates to a pair of spectacles according to claim 1.
- a pair of glasses is known in which both the upper edge of the glasses and the lower edge are covered by a tension wire or by a strap to secure the glasses.
- the nose bridge and the jaw parts have clips that are bolted to the nose bridge or the jaw parts.
- threads for attaching the lenses two holes in the clips or metal pads are provided through which each end of the thread is pulled like a loop, the thread can be tightened by simply tightening the two thread ends. It is therefore no soldering or welding of the thread ends required.
- the glasses frame consists of numerous items, which must be made relatively complicated and assembled. Furthermore, the glasses are less torsionally stiff.
- a pair of glasses in which the mentioned disadvantages are overcome.
- a pair of glasses is to be created in which a completely borderless appearance is ensured and yet good stability and tantssteif ⁇ gkeit the glasses frame can be achieved.
- the manufacturing cost of the items are to be kept as low as possible and the assembly of items to the glasses frame be designed particularly simple.
- the upper or lower edge is bordered by a band-shaped frame part for holding the lenses.
- a band-shaped frame part for holding the lenses.
- the band-shaped frame part is guided in a groove in the edge of the glass.
- Edge of the glasses bordered by a wire or thread This offers the advantage of a virtually invisible enclosure of the glasses even in these areas.
- the wire or thread is connected at a first end to the nose bridge and at another end to its associated jaw part.
- the connection with these parts is done by grinding the threads in one or more holes in the nose bridge or in the jaw part.
- Behind the hole (s) the wire or thread can be knotted, or in the case of a synthetic thread, it can be heated, causing it to melt (with appropriate choice of material, such as nylon) and form a thickening.
- the thread end is secured against slipping through the hole or the hole.
- the jaw members and their associated temple bow are made in one piece from an elastic material, which further reduces the number of components used and thus the manufacturing costs and assembly costs.
- each hooking connection consists of a hook, double hook or mushroom-shaped element, which is integrally formed on an element of the glasses such as the band-shaped frame part, which surrounds the upper edge of a glass.
- a corresponding counterpart of the hook connection such as a slot or an opening, is accordingly provided on the nose bridge and / or on the lateral jaw parts.
- the hook element could for example be provided on the nose bridge and the slot or the opening on the band-shaped frame part.
- Fig. 1 is a front view of a spectacle according to the invention.
- Fig. 2 is an enlargement of the spectacles of Fig. 1 in the region of a jaw member.
- Fig. 1 shows a schematic front view of a spectacle according to the invention.
- Two glasses 10 are connected to a nose bridge 12 and two lateral jaw parts 16.
- eyeglass temple 14 are integrally formed on the jaw parts 16 eyeglass temple 14 .
- the material for jaw parts 16 or temple 14 is chosen so that it is sufficiently elastic to perform a pair of glasses in a known manner hingeless.
- a spring-elastic metal is used.
- the glasses 10 are bordered at their lower edges each with a thread 20.
- a nylon thread is used, which is guided in a groove 19 which is formed laterally in the edge of the glasses 10 (indicated in sections in the figures).
- a metal wire may also be used.
- the thread 20 is attached at one end to the side jaw member 16 with another end to the nose bridge 12.
- the upper edges of the glasses 10 are bordered by means of a band-shaped frame part 18. This is made so thin in cross section (for example, with a rectangular or square cross section 0.5mm wide and 0.5mm high or thinner) that the rimless impression of the glasses is maintained.
- the bands are guided in a (partially shown) groove 19 in the edge of the glasses 10 and secured against slipping.
- the flat strips are preferably made of such a resilient material such as a metal that they can be placed around glasses 10 of different shapes. This offers the advantage that only the length of the nylon thread 20 and the band-shaped frame part 18 must be varied to adapt the glasses frame to different glasses. Overall, one thus obtains a system in which standardized nose bridges 12 can be combined with a wide variety of lens shapes. For final assembly of a pair of glasses, for example, an optician then only has to select a band-shaped frame part 18 with an appropriate length so that nose bridge 12 and jaw part 16 are at an intended height.
- An eyewear according to the invention has, besides the advantage that a rimless appearing glasses is formed by the flat strips 18 together with the threads 20, also the advantage that it has a high stability and connection stiffness by the use of flat strips 18. Holes in the lenses 10 are not required.
- FIG. 2 shows an enlarged detail of the spectacles of FIG. 1 in the region of the left-hand jaw part 16.
- the jaw part 16 has two through holes or bores 22 and 24.
- the thread 20 made of nylon drawn only in the region of the jaw 16
- the thread 20 is guided with its back end 22 first through the first hole 24 from the glass 10 on the outside of the jaw member 16 and then through the second hole 22 again by the jaw member 16th back to a region between glass 10 and jaw 16.
- the thread 20 is jammed in the holes 24 and 26.
- a hooking connection is provided, which consists of a mushroom-shaped element 28 (completely visible, since the jaw member 16 is partially drawn transparent ), which is integrally formed on the band-shaped frame part.
- a manufacturing method for example, laser cutting, wire eroding, water jet cutting and etching can be used.
- the hook element 28 can also be soldered or welded to the frame part 18. The element 28 engages in an opening 30 (indicated by gray background) of the jaw part 16.
- Shape and size of hook member 28 and opening 30 are chosen so that for mounting the hook member can be inserted through the opening 30 therethrough. Due to the tension of the thread 20 and the force by means of which the elastic band-shaped frame member 18 pushes the hook member 28 outwards (the band-shaped frame member 18 is preferably aligned about the glass 10 prior to application), the hook hooks above the upper edge of the Opening 30 projecting portion of the element 28 with the upper edge of the opening 30 so that a Einhakthetic is effected, which can be solved only by unthreading the thread 20 or pressing the hook member 28 down.
- a hook-shaped element can also be provided on the jaw part 16 and corresponding to an opening then on the band-shaped frame part 18.
- the two elements of the hooking connection are then designed so that a flush inner edge of the frame is formed and Glasses without steps in the side edge can be used.
- a similar connection of the thread 20 is provided with the nose bridge 12 corresponding to the connection with the side jaw member 16.
- the connection of the band-shaped frame part 18 with the nose bridge 12 is a hooking connection, as already explained with reference to FIG. 2 between the band-shaped frame part 18 and the side jaw member 16.
- a pair of glasses according to the invention can also be constructed so that a band-shaped frame member is provided in the lower region of the glasses 10 and correspondingly a version of the glasses in the upper region by means of a nylon thread or glasses, in which both Edges of the glasses are bordered with band-shaped frame parts, which enter into Einhakeuren with the jaw parts and the nose bridge each.
- a particularly simple mountability of the glasses is achieved by the hook connections used. This can be done in the glasses of the two figures, for example, that initially two nylon threads 20 are brought to desired length and attached to the jaw members 16 and the nose bridge 12 (looped through two holes and jammed or passed through only one hole and knotted at the end or melted to a thickening).
- the two band-shaped frame parts 18 are hooked into the jaw members 16 and the nose bridge 12 and the glasses completed.
- the frame members 18 and threads 20 are held on tensile stress and the hook elements 28 inserted through the openings 30, where they interlock with partial relief of the tension.
- the glasses 10 can be pressed into this after the assembly of the jaw members 16 with the brackets 14 and the nose bridge 12 existing spectacle frame.
