Definitions
- the invention relates to an eyeglass temple which defines a longitudinal direction, comprising a plastically deformable rod with a longitudinal direction and a cross-linked, elastically deformable polymer, the polymer completely surrounding the rod in the longitudinal direction, and the longitudinal direction of the rod essentially following the longitudinal direction of the eyeglass temple.
- the invention also relates to a spectacle frame comprising at least one such spectacle temple.
- a pair of glasses includes see-through areas, e.g. Spectacle lenses. Furthermore, it usually has a frame and a holding device, preferably eyeglass temples, particularly preferably ear hooks, for stabilizing and fixing the see-through areas.
- the holding device is usually attached to the socket.
- the frame When the glasses are worn, the frame usually rests on the nasal bone, while the temples rest on the base of the ear between the ear and the skull in order to prevent the glasses from slipping off.
- glasses temples with spacer elements are described in DE 20 2016 106 952 U1, which enable the temple length to be easily adapted to the shape of the user's head.
- the holding device is formed from a loop or a band which is to be arranged around the head of the user, that is to say also runs around the back of the head of the spectacle wearer.
- Such loops or straps allow an individual fixation of the glasses but are perceived as unsightly and uncomfortable.
- Such holding devices are therefore only found in specific areas of application, e.g. as work safety goggles and sports goggles, such as diving goggles, use.
- DE 10 2004 002 700 A1 describes an adjustment of the snug fit of glasses by means of a rear ear holding section.
- the rear-ear holding sections can be designed to be displaceable, extendable or bendable in order to enable adaptation to the needs of the respective user.
- the eyeglass temples described in the prior art only allow an adjustment of the degree of fixation of the glasses on the user's ear, for example by adjusting the length of the eyeglass temple and the alignment of a rear ear holding section.
- Other individual aspects such as setting the angle of spread of the temple to adapt to a wider or narrower head shape or adjusting the tilt angle of the temple, whereby the inclination of the frame or the transparent areas can be changed to adapt to the cheekbones, are not taken into account.
- the object of the present invention is therefore to provide an eyeglass temple which can be reversibly adjusted in any direction for an individual fit and which in particular can also change the inclination of a frame attached to it, including the see-through areas.
- it is of interest to simplify the individual adaptation in such a way that the user can carry it out independently, reversibly, non-destructively and without additional tools.
- an eyeglass temple which defines a longitudinal direction, comprising a rod that is plastically deformable at room temperature with a longitudinal direction and a cross-linked, elastically deformable polymer, the polymer completely surrounding the rod in the longitudinal direction, and the longitudinal direction of the Rod essentially follows the longitudinal direction of the temple.
- the cross section of the plastically deformable rod can be round, oval, rectangular or square.
- the aspect ratio of the plastically deformable rod i. the ratio of the extent of the rod in the longitudinal direction to its extent perpendicular to the longitudinal direction is, for example, 15-150 and preferably 30-100.
- the rod is at room temperature, i.e. plastically deformable at about 20 ° C, and in particular in a temperature range between -20 ° C and 70 ° C.
- the force to be applied for a deformation is preferably less than 50 N, for example 5-50 N and in particular 10-50 N.
- the rod can ideally be bent by hand at room temperature, i.e. be bendable, so that an adaptation of the temple by the user himself, in cold adjustment, that is, without heating the temple, is possible at any time.
- the plastically deformable rod comprises at least one metal or a metal alloy.
- the optionally alloyed metal can be selected from aluminum, zinc, titanium, iron, Copper, silver, nickel or a mixture thereof.
- the optionally alloyed metal is preferably selected from iron, copper, silver, nickel or a mixture thereof.
- Preferred metal alloys are steel or nickel silver.
- the plastically deformable rod can be, for example, a metal wire or a metal alloy wire.
- Suitable modification can be chemical, e.g. with hydroxyl and / or amino groups. Suitable modification methods are known to the person skilled in the art and include coating with a compound containing hydroxyl and / or amino groups and treatment in plasma e.g. by means of physical vapor deposition (PVD), chemical vapor deposition (CVD) or reactive gas plasma treatment.
- PVD physical vapor deposition
- CVD chemical vapor deposition
- reactive gas plasma treatment By modifying the rod, better compatibilization of the rod surface with the cross-linked, elastically deformable polymer can be achieved.
- a chemical and / or physical, in particular covalent, bond to the polymer can preferably be achieved by modifying the surface of the rod.
- the plastically deformable rod can be structured transversely to the longitudinal direction.
- the rod is at least partially notched or roughened at regular intervals.
- the structuring of the plastically deformable rod enables improved adhesion of the elastic polymer to the rod, in particular when forces act in the longitudinal direction.
- Both the surface modification and the structuring of the rod provide a defined position of the polymer in relation to the rod even under mechanical stress, e.g. when bending the temple, sure. This prevents the polymer from separating from the rod.
- the plastically deformable rod extends over at least 80%, preferably 85-95%, of the length of the temple, in particular essentially over the entire length of the temple.
- the plastically deformable rod can extend essentially as far as a rear end of the eyeglass temple, in order to end preferably essentially flush with a surface of the crosslinked polymer.
- the plastically deformable rod ends flush with a surface of the crosslinked polymer in the region of the rear end of the temple arm.
- the plastically deformable rod is completely surrounded by the crosslinked polymer in the region of the rear end of the temple, the rod preferably extending up to a predetermined distance, such as approximately 1 -4 mm a rear end of the temple extends.
- At least one end, in particular the front end and the rear end, of the plastically deformable rod is completely surrounded by the crosslinked polymer.
- the plastically deformable rod preferably has at least one end that is flush with a surface of the crosslinked polymer, in particular a front and a rear end that is flush with a surface of the crosslinked polymer.
- the plastically deformable rod can extend up to a predetermined distance in front of the front end of the temple, the predetermined distance preferably being about 3-30 mm, more preferably about 15-25 mm.
- a “front end of the temple arm” in the sense of the present invention is in particular an end of the temple arm provided for a face-side arrangement; a “rear end of the temple” in the sense of the present invention is, in particular, an end of the temple provided for an ear-side arrangement.
- the plastically deformable rod can be straight, curved, curved or otherwise aligned in the longitudinal direction in the temple.
- the rod ends in a bend in the area of the front end of the temple piece, the bend preferably being approximately 60-90 °, preferably 90 °.
- the plastically deformable rod preferably ends in the area of the front end of the temple piece, essentially flush with a surface of the crosslinked polymer. This geometry of the rod simplifies the production of the temple in the casting process considerably.
- the polymer is crosslinked, i.e. the polymer chains are three-dimensionally linked to one another via chemical, in particular covalent, cross-linking points. Loosening and re-forming of crosslinking points is not possible here, not even under the action of heat.
- the elastically deformable polymer is therefore not a thermoplastic.
- the crosslinked polymer is elastically deformable at room temperature (i.e. about 20 ° C) and in particular in a temperature range between -20 ° C and 70 ° C.
- the crosslinked, elastically deformable polymer has a shape memory effect, i.e. In spite of a major transformation in the meantime, it assumes its former external shape again without the application of force.
- the holding force of the plastically deformable rod which corresponds to the deformation resistance of the rod, in particular exceeds that in the temple according to the invention Restoring force of the elastically deformable polymer, which acts when the temple is deformed in the direction of the earlier external shape of the polymer.
- This enables simple and individual adaptation of the shape of the temple.
- a user can thus adapt the temple according to the invention individually to the personal fit and the respective application - a tight fit, for example during sporting activity and a loose fit, for example in everyday life, at room temperature and without further aids.
- the adjustment can be made as often as required within the life cycle of a pair of glasses (e.g. about six years) without any damage to the rod or polymer being observed.
