The present invention distinguishes from the teachings of these patents as contemplating the use of the repelling force of adjacent like poles of separate magnets to releasably fasten sunglasses to eyeglasses. Each of the above-listed patents relies upon the attractive force of adjacent magnets with opposite poles facing one another to releasably fasten sunglasses to eyeglasses.

SUMMARY OF THE INVENTION The present invention relates to sunglasses attached to eyeglasses using repelling magnetic force. The present invention includes the following interrelated objects, aspects and features :

(1) In a first aspect, the present invention is directed to sunglasses designed to be removably attached to existing eyeglasses. The existing eyeglasses may have eyeglass rims to which are attached, on the outboard sides, frame pieces or side extensions that curve around from the plane of the eyeglass lenses to a direction approximately 90° rotated therefrom., facing rearwardly, and to which are pivotably attached temples designed with distal ends placeable over the ears of the user to affix the eyeglasses to the head of the user. On the inboard side of the eyeglass rims, a bridge interconnects them and nose pieces may be provided to cushion the nose when the eyeglasses are supported thereon. (2) The sunglasses usable in accordance with the teachings of the present invention have a bridge to which is attached, to either side, sunglass rims which carry sunglass lenses that can be permanently tinted or can, if desired, be of the "PHOTOGRAY" type which darkens upon exposure to light, and lightens when the ambient light intensity diminishes.

(3) The present invention contemplates magnetic attachment means designed to releasably attach the sunglasses to the eyeglasses. In accordance with the teachings of the present invention, the attachment means consists of a rearwardly facing arm on the sunglasses to which a magnet is affixed, at each location, and magnets affixed on the eyeglasses in alignment with the magnets on the sunglasses.

(4) At each side of the eyeglasses, just outboard of the eyeglass rims, L-shaped brackets are provided that have C- shaped cross-sections. The magnets are arranged, on each side of the eyeglasses and sunglasses, respectively, so that when the sunglasses are placed into adjacency with the eyeglasses, like poles of the adjacent magnets face one another to create a repelling force therebetween. The repelling force forces the magnets carried on the sunglasses rearwardly away from the magnets carried on the eyeglass frames, and into a recess formed by the C-shaped cross-section of the L-shaped brackets. The repelling force between the magnet pairs retains the magnets carried by the sunglasses within the recesses in the L-shaped brackets to maintain the sunglasses mounted on the eyeglasses. The sunglasses are easily removed by moving them and their magnets toward the eyeglasses magnets and then upwardly.

(5) If desired, lateral stoppers may be provided within the C-shaped cross-sectional channel of the L-shaped brackets to preclude lateral movement of the sunglasses with respect to the eyeglasses .

(6) If desired, the present invention is equally usable in conjunction with eyeglasses and sunglasses in which the lenses are of the rimless support type in which fasteners are inserted through the lenses themselves to attach a bridge between the lenses and to attach temples and earpieces outboard of the lenses .

Accordingly, it is a first object of the present invention to provide sunglasses attached to eyeglasses using repelling magnetic force.

It is a further object of the present invention to provide such a device in which an L-shaped bracket is employed to retain the sunglasses in position under the repelling force of adjacent magnets .

It is a still further object of the present invention to provide such a bracket having a C-shaped cross-section designed to retain the sunglasses in vertical orientation with respect to the eyeglasses.

It is a yet further object of the present invention to provide such an invention in which lateral stoppers are provided to maintain lateral alignment between the eyeglasses and sunglasses .

These and other objects, aspects and features of the present invention will be better understood from the following detailed description of the preferred embodiment when read in conjunction with the appended drawing figures.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows an exploded perspective view of the present invention.

Figure 2 shows a top view of the present invention as assembled.

Figure 3 shows a view similar to that of Figure 2 but enlarged to show details.

Figure 4 shows a cross-sectional view along the line 4-4 of Figure 3.

SPECIFIC DESCRIPTION OF THE PREFERRED EMBODIMENT With reference, first, to Figure 1, a pair of eyeglasses in accordance with the teachings of the present invention are generally designated by the reference numeral 10 and are seen to include eyeglass rims 11 and 13 connected together by a bridge 15 with nose pieces 17 and 19 provided for well known purposes. Side extensions 21 and 23 extend outwardly from the rims 11 and 13, respectively, and include substantially right angle bends so that their ends remote from the eyeglass rims extend rearwardly. With further reference to Figure 1, the side extensions 21 and 23 have respective hinges 25 and 27 connecting to respective temples 29 and 31 that have respective ends 33 and 35 designed to fit over the ears of the user. Eyeglass rim 11 carries the lens 12, while eyeglass rim 13 carries the lens 14.

The side extension 21 carries an L-shaped bracket 22, while the side extension 23 carries an L-shaped bracket 24. The side extension 21 also carries a magnet 26, while the side extension 23 also carries a magnet 28. This structure is also seen, generally, with reference to Figure 2.

With further reference to Figure 1, sunglasses in accordance with the teachings of the present invention are generally designated by the reference numeral 40 and include sunglass rims 41 and 43 with the sunglass rim 41 holding a sunglass lens 42 and with the rim 43 holding a sunglass lens 44. A bridge 45 interconnects the rims 41 and 43. Side extensions 46 and 47 are attached, respectively, outboard of the rims 41 and 43. At the rear termination of the side extension 46, a magnet 49 is provided. At the rear termination of the side extension 47, a magnet 51 is provided.

With reference, now, to Figures 3 and 4, a better understanding of the attachment means releasably holding the sunglasses 40 to the eyeglasses 10 will now be described. As seen in Figure 4, the L-shaped bracket 22 has a C-shaped cross- section, the cross-section including horizontal legs 30 (top) and 32 (bottom), and a vertical leg 34. The legs create an internal chamber 55 having a vertical dimension slightly larger than the vertical dimension of the magnet 49. As best seen in Figure 3, the bracket 22 may include lateral stoppers 57 and 59 which limit the ability of the magnet 49 to move laterally within the channel 55.

With particular reference to Figure 4, it is seen that the magnets 26 and 49 are oriented so that in the position shown in Figures 3 and 4, in particular, like poles face one another. In the example shown, with particular reference to Figure 4, the North poles "N" face one another. The invention operates equally effectively where the South poles "S" face one another in the view of Figure 4.

In the operation of the present invention, in the view of Figure 4, the magnet 49 is lowered from above the magnet 26 and bracket 22 until it enters the space between the magnet 26 and the chamber 55. The repelling force created between adjacent magnets with like poles facing one another causes the magnet 49 to be repelled from the magnet 26 and into the chamber 55 where it is captured between the legs 30 and 32 to preclude vertical movement with respect to the bracket 22. The lateral stoppers 57 and 59 (Figure 3) preclude lateral movement of the magnet 49 within the bracket 22.

The repelling force between the magnets 26 and 49 (and correspondingly between the magnets 28 and 51) maintains the magnet 49 within the channel 55 of the bracket 22 and the magnet 51 within the corresponding channel (not shown) within the bracket 24 (see Figure 2) . In this way, the sunglasses 40 are releasably retained on the eyeglasses 10.

The repelling force between the adjacent magnets with like poles facing one another provides an additional advantage nowhere taught or suggested by the prior art. That advantage is the fact that the repelling force between the adjacent magnets acts as a "shock absorber" so that if the eyeglasses 10, sunglasses 40 combination is jarred, the sunglasses 40 may slightly move away from the eyeglasses 10 through the cushioning effect of the repelling force between the adjacent magnets and, once the jarring has ceased, the magnets 49 and 51 will again restore their locations within the respective brackets 22 and 24. The sunglasses are easily removed from the eyeglasses by moving them and their magnets toward the eyeglasses magnets and then upwardly.

It is noted, with reference to Figure 4, that the side extension 46 includes a downwardly extending projection 48 to which the magnet 49 is affixed. The side extension 47 has similar structure to which the magnet 51 is affixed.

As such, an invention has been disclosed in terms of a preferred embodiment that fulfills each and every one of the objects of the invention as set forth hereinabove, and provides a new and useful pair of sunglasses attached to eyeglasses using repelling magnetic force of great novelty and utility.

Of course, various changes, modifications and alterations in the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof.

As such, it is intended that the present invention only be limited by the terms of the appended claims.
