Spectacles with interchangeable lenses

Abstract

Spectacles with interchangeable eyeglass lenses (2), where the spectacles comprise a spectacles frame (1) and eyeglass lenses (2), where the eyeglass lenses comprise a mount (3) which is secured to an outer edge of the eyeglass lenses, and where at least one of the mount and the spectacles frame comprises a coupling element (8), which can couple together the mount (3) and the spectacles frame (1), thereby producing a spectacles frame in which the eyeglass lenses can be replaced as desired. Furthermore, the mount or the spectacles frame comprises an oblong recess (5) designed to receive a partial section (7) of the spectacles frame or a bulge on the mount. Said spectacles are suitable for use at work, bicycling in blustery weather, or skiing in harsh sunlight.

DETAILED DESCRIPTION OF THE INVENTION

(21) FIG. 1 shows a spectacles frame 1 during mounting of interchangeable eyeglass lenses 2, where it is seen that the eyeglass lenses 2 comprise a mount 3, which is secured to an outer edge 4 of the eyeglass lenses 2.

(22) It is likewise seen that the mount 3 comprises an oblong recess 5 designed to receive a partial section of the spectacles frame 1, where the spectacles frame 1 comprises a substantially m-shaped elastically deformable front bridge 6.

(23) The actual coupling between the mount 3 and the spectacles frame 1 is explained more closely in the following.

(24) The FIGS. 1, 2 and 3 moreover show that the mount 3 comprises at least one partial section 7 for influencing of the penetration of light and/or for influencing an air flow at one side of the eyeglass lens 2.

(25) The FIGS. 2, 3 and 4 show a spectacles frame 1 after mounting of interchangeable eyeglass lenses 2. Thus, there is shown a part of spectacles, where the spectacles comprise the spectacles frame 1 and an interchangeable eyeglass lens 2

(26) The FIGS. 5 and 6 show a spectacles frame 1 without eyeglass lenses 2, where it is seen that the spectacles frame 1 comprises two coupling elements 8, which can couple together the mount 3 and the spectacles frame 1.

(27) Where a spectacles frame 1 has a side bar 9 on either side of a front bridge 6 and a nose bridge or two nose pads 10, FIGS. 5 and 6 show coupling elements 8 both at the side where the side bar 9 is placed and in the middle where the nose pad 10 is placed.

(28) FIG. 7 shows a detail of a coupling element 8 at the side where the side bar 9 is placed.

(29) As an alternative embodiment of the spectacles frame 1 shown in the FIGS. 5 and 6, the FIGS. 8 and 9 show a spectacles frame 1 without eyeglass lenses 2 revealing that the spectacles frame 1 comprises two coupling elements 8 which can couple together the mount 3 and the spectacles frame 1.

(30) In the embodiment shown in FIG. 8, the one coupling element 8 is in the shape of a tooth 11, while the other coupling element 8 is in the shape of a hook 12. The tooth 11 may preferably be formed as a pin 19 which is designed to interact with a hook 12′ (see FIG. 10) in the mount.

(31) In the embodiment shown in FIG. 9, both coupling elements 8 in the spectacles frame are formed as teeth 11.

(32) Thus, there can be coupling elements 8 in many embodiments, where there are one, two, or more teeth, hooks, pins or other types of coupling elements 8 which are able to couple together a mount 3 and a spectacles frame 1.

(33) As an alternative embodiment of the eyeglass lens 2 shown in FIGS. 1 to 4, FIGS. 10 and 11 show schematically an eyeglass lens 2 in an alternative embodiment for coupling to a spectacles frame 1.

(34) FIGS. 10 and 11 show schematic cross sections through an eyeglass lens in a mount. For clarity, the transition between the mount and the eyeglass lens is not shown, since these figures serve to show the coupling elements more clearly.

(35) In the embodiment shown in FIG. 10, the one coupling element 8′ in the mount is in the form of a tooth 11′, while the other coupling element 8′ is in the form of a hook 12′. In the embodiment shown in FIG. 11, both coupling elements 8′ are in the form of hooks 12′.

(36) As mentioned above, there may thus be coupling elements 8′ in many embodiments, where there are one, two, or more teeth, hooks, pins or other types of coupling elements 8′ which are able to couple together a mount 3 and a spectacles frame 1.

(37) FIG. 12 shows that the recess 5 has a funnel-shaped entry opening 13. This makes it easier to introduce the platelike frame in the recess 5.

(38) FIGS. 13 and 15 show another embodiment where the partial section 7 of the mount 3 comprises breakthroughs of material in the form of gaps 14.

(39) FIGS. 14 and 16 show a third embodiment where the partial section 7 of the mount 3 comprises breakthroughs of material in the form of holes 15

(40) These breakthroughs 14, 15 of material will influence the air flow past the spectacles. They also contribute to the ornamental appearance of the spectacles.

(41) FIG. 17 shows a partial cross section through a mount 3 and a spectacles frame 1 as illustration of a recess 5′ in the spectacles frame. The recess 5′ receives a bulge 16 which is formed on the outside of the mount 3, at least in the region for engagement with the spectacles frame 1.

(42) FIG. 18 shows a partial image of a spectacles frame 1 seen from the front without eyeglass lenses. It is seen here that the one coupling element 8 is in the form of a tooth 11, while the other coupling element 8 is in the form of a U-shaped notch 17. The notch 17 may preferably be formed to interact with a pin 19 which is mounted in aligned boreholes 18 (see FIG. 3) in each side wall of the recess 5 of the mount 3. The pin will preferably be a metal pin. A metal pin will be a stable and strong coupling element for engagement with the frame hook.
