DESCRIPTION OF THE PREFERRED EMBODIMENTS
Now, preferred and alternative embodiments of the present invention in relation with an interchangeable spectacles and sunshade clip assembly will be described in detail with reference to the annexed drawings.
FIGS. 1 to 5 illustrate an interchangeable spectacles and sunshade clip assembly in accordance with a preferred embodiment of the present invention, and FIGS. 6 and 7 illustrate different alternative embodiments of the present invention.
In the following description, since left and right sides of respective elements, namely, sunshade clip, spectacles and a spectacle frame, are symmetrical, only one side will be designated by reference numerals and explained, except for lens units thereof. Further, the constituent elements of alternative embodiments corresponding to those of a preferred embodiment of the present invention are designated by the same reference numerals.
The interchangeable spectacles and sunshade clip assembly of the present invention comprises spectacles 1, a spectacle frame 50 to be detachably attached to the spectacles 1 to form a spectacles/spectacle frame assembly, and a sunshade clip 100 to be detachably attached to the spectacles/spectacle frame assembly.
The spectacles 1, spectacle frame 50 and sunshade clip 100 are selectively attachable to one another by means of magnets, which are appropriately positioned such that opposite polarities face.
Referring to FIGS. 1 and 2, the spectacle frame 50, as a basic framework of the interchangeable spectacles and sunshade clip assembly according to the present invention, comprises a frame bar 55 integrally formed with a pair of temple arms 51 with no hinge. Here, the shape of the temple arms 51 is not limited only to that shown in the annexed drawings, but also includes various designs.
That is, the frame bar 55, integrally formed with or hingedly connected to the temple arms 51, takes the form of an upper rim portion of a conventional spectacles lens frame. Thereby, the frame bar 55 serves as a basic frame to which both the spectacles 1 and the sunshade clip 100 are detachably attached.
At the center of the frame bar 55 is integrally affixed a magnet piece 56 extending rearward, i.e. protruding toward the spectacles 1. The magnet piece 56 takes the form of a flat plate piece made of metal, and incorporates one or more highly-magnetic magnets M1. Alternatively, the magnet piece 56 itself is a magnetized element having the function of a magnet.
The spectacles 1, to be detachably attached to the spectacle frame 50, comprise a pair of lenses 10 and 11. In a preferred embodiment of the present invention, the lenses 10 and 11 have no lens frames and are connected to each other by means of a bridge 15. Here, the bridge 15 is bolted to the lenses 10 and 11.
At the center of the bridge 15 is affixed an approximately U-shaped insert 20 so as to correspond to the magnet piece 56 of the frame bar 55. The insert 20 consists of a pair of upper and lower insert pieces 21 and 22, and one or more magnets M2 are inserted into one of the insert pieces 21 and 22. Meanwhile, instead of the above described spectacles 1 having no lens frames, other spectacles, such as metal-rimmed spectacles, are also applicable to the present embodiment so as to achieve the same operational effects as the rimless spectacles 1.
With such a configuration as described above, the magnet piece 56 of the frame bar 55 is fitted into the insert 20 of the spectacles 1 and is fixedly attached thereto through attachment of the magnets M1 and M2.
Herein, in order to ensure more various combination of the spectacles and spectacle frame, there are provided a plurality of spectacles and spectacle frames having different shapes, enabling production of various designs of the spectacles/spectacle frame assembly.
To the spectacles/spectacle frame assembly is detachably attached the sunshade clip 100 to function as sunglasses.
In the preferred embodiment of the present invention, the sunshade clip 100 comprises a pair of sunshade lenses 101 and 102 having no lens frames, and an injection molded sunshade bridge 105 to connect the sunshade lenses 101 and 102 to each other. It will be recognized that the shape of the sunshade clip 100 is not limited only to the preferred embodiment, but also includes various designs, such as sunshade clips having sunshade lens frames.
At the center of the sunshade bridge 105 of the sunshade clip 100 is provided an approximately U-shaped coupling insert 110, which is integrally injection molded with the sunshade bridge 105. The coupling insert 110 is positioned to correspond to the magnet piece 56 of the frame bar 55 fitted in the insert 20 of the spectacles 1. The coupling insert 110 consists of a pair of upper and lower insert pieces 111 and 112, and a magnet M3 is inserted into a respective one of the insert pieces 111 and 112.
The upper and lower insert pieces 111 and 112 of the coupling insert 110 define a gap having a predetermined width T therebetween. The predetermined width T is determined to receive the insert 20 fitted with the magnet piece 56.
With such a configuration, the sunshade clip 100 is attached to or detached from the spectacles/spectacle frame assembly by means of the coupling insert 110 thereof, and can be selectively used as occasion demands.
As stated above, the interchangeable spectacles and sunshade clip assembly of the present invention is achieved by combining the spectacles 1, spectacle frame 50 and sunshade clip 100 freely selected from among a plurality of various different designs of spectacles, spectacle frames and sunshade clips depending on the wearer's taste. This means that the assembly of the present invention can be embodied into various designs.
FIG. 6 illustrates an alternative embodiment of the present invention. In the present embodiment, the sunshade clip 100 comprises a coupling insert 110-1, which has an approximately L-shaped form so that it is seated and attached onto an upper surface of the insert 20 of the spectacles 1. This allows the sunshade clip 100 to be more easily attached to or detached from the spectacles 1.
FIG. 7 illustrates another alternative embodiment of the present invention. Here, the sunshade clip 100 comprises a coupling insert 110-2, which has a planar protrusion form and incorporates the magnet M3. In this case, by making use of only a magnetic force of the magnet M3, the coupling insert 110-2 can achieve the same operational effects as the previous embodiments. As shown, the coupling insert 110-2 of the sunshade clip 110 is attachable to the spectacles 1 from above and below of the insert 20 of the spectacles 1. In the present embodiment, the sunshade clip 110 is configured to have sunshade lens frames.
In the above description, although it is explained that the magnet piece 56 of the spectacle frame 50, the insert 20 of the spectacles 1, and the coupling insert 110 of the sunshade clip 100 incorporate the plurality of magnets M1, M2 and M3, respectively, it is possible to achieve the same operational effects as the above described configuration even if one of the corresponding elements is made of a magnetically-induced material, and the other one is provided with the magnets, or one of the corresponding elements is magnetized to function as a magnet.
As apparent from the above description, the present invention provides an interchangeable spectacles and sunshade clip assembly in which spectacles and a sunshade clip, which are freely selectable from among various designs of spectacles and sunshade clips, are selectively attached to a spectacle frame as a basic framework, resulting in various designs of the assembly to meet the wearer's taste.
Although the preferred embodiment of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
