Description
AUXILIARY LENS UNIT FOR GLASSES
Fpi~I~.D OF THE INVENTION
The present invention pertains to eyeglasses and in particular to an auxiliary lens unit that may be detachably mounted to a primary lens unit.
BAGKCiR~IND OF THE INVENTION
It Is commonplace for prescription eyeglasses to be fitted with a detachable auxiliary lens unit that is tinted for protecting one's eyes against the sun. Colloquially known as "clip-ons", these auxiliary lens units have been mechanically mounted, or clipped on to the primary lens unit. For example, U.S. Patent Na. 3,876,295 to Loughner shows a typical "clip on" design. Over the years, various styles of mechanical clipping have been devised, Such 2~s shown in U.S. patent 6,088,708 to Ku which discloses a snap~fit, rotatable connection at the bridge of the auxiliary lens unit. "Clip ons" have as a common element in their design a mechanical attachment which positively, releasably clips the auxiliary frame unit to tha primary frames. These positive mechanics) connections, however, have the disadvantage of being difficult to snap into, and out of, place and can experience significant mechanical wear over time.
Another attachment means recently gaining.favQUr is the use of magnetic connectors between the auxiliary and primary lenses. For example, 2D U_S. Patent No. 5,737,054 to Chao discloses an auxiliary lens unit having a magnet on a middle bridge portion of the unit which mates with a magnet on the primary frame. Similarly, U.S- Patant No. 6,053,691 to Ku shows a yoke and magnet combination on the nose bridge. While these magnetic units simplify use over previous mechan(cal "clip cns", there are also disadvantages-For example, since a magnetic connection is weaker than a mechanical one, magnets of significant size must be used. Referring to Figure 1 of Ku '611, this results in a rather unsightly and aesthetically unpleaslng lump on the bridge of S 3~Hd ' Q I ~ 110213 BS ~ B I 00-aZ-d38 ..z-the primary frame. Considering that the auxiliary sunglass unit is perhaps used by the wearer less than 10% of the tote! wearing time (i-e- it is used onty when the wearer is outside in a sunny condition), the thick and bulky bridge of Ku '611 on the primary frame is difficult to justify to the consumer. In a highly competitive industry, in which eyeglasses are as much a fashion item as a useful article, the consequence of an aesthetically displeasing effect such as this cannot be underestimated.
Magnets suffer from diminished strength over time such that they became less useful after a year or two. Also, magnets provide, In essence, a point-to-point type of connection which can affect the integrity of the connection.
The use of magnets also tends to increase manufactur(ng complexity and costs.
Accordingly, there is a need for an improved eyeglass and auxiliary lens unit system which is both easy to use and aestheticailly pleasing.
SUMMARY OF THE INVENTION
The pr~sent invention provides an eyeglass device Comprising a primary fens unit for supporting a, pair of primary lenses therein, the primary Ipns unit Including a first bridge, the first bridge having smooth upper and lower surfaces, and an auxiliary lens unit for supporting a pair of secondary tenses therein, the auxiliary lens unit including a second bridge, the second bridge including a non-magnetic connection member for detachably connecting the second bridge to the first bridge, the connection member having a pair of smooth opposed inner surfaces spaced apart from one another, the opposed surfaces adapted to slidably engage the upper and lower surfaces over a region.

DEfAIi~D DESCi~IP N OF THE i~REFERRED lBhiIBOIDIMENTs An eyeglass device in accordance with the present invention is shown in the Figures generally at 20.
The description includes directional terms such as "upper", 'lower", "front" and "read' and variations thereof to refer to elements of eyeglass device 20. These terms should be understood to relate to the orientation of the eyeglass device when it is worn on the head of a user. Thus, "upper'' refers to a G 3~tf d ° Q I ~ YI0213 00 ~ B t 00-AZ-d38 surface that faces generally toward the sky and "lower refers to a surface that faces generally toward the ground. "Rear" refers to a surface that faces generally toward the bade of the user's head and "front" refers to a surface that faces generally away from the user's face.
Referring to Figures 1 to 4, the eyeglass device 20 includes a primary lens unlt 22 and an auxiliary lens unit 24. Primary lens unit 22 includes a pair of lenses 26 supported by rims 28 arid Spanned by a bridge 3a. A Side extension member 32 extends from each side of primary lens unit 22 and has a laterally extending portion 34 and a rearwardly extending portion 36. A pair of temple arms 38 are pivotally mounted with a hinge 40 to the rearwardly extending portion 36. Extending below bridge 30 are a pair of nose pads 42 supported by nose pad supports 44. Nose pad supports 44 are either integrally formed with rims 28 (not shown] or mounted to rims 2$ by fasteners 46 (as shown) suoh as Solder, welds, glue or screw fasteners as known in the art.
The auxiliary lens unit 24 includes a pair of lenses 60 that are typically tinted to protect a person's eyes against the sun. The lenses 80 are supported in rims 62 that pare spanned by a bridge 64. Bridge 64 includes a connecting member fib extending rearwardly from bridge 30 and extending substantially between rims 62.
Referring to Figure 5a, Car~nection member 66 is non-magnetic and has a pair of spaced-apart and opposed smooth inner surtaces 68.
Surfaces 88 are adapted to slidably receive bridge 30 and slidingly contact and engage smooth upper and lower bridge surfaces 89 an bridge 30.
Surtaces 68 are preferably substantially parallel to one another in a rearward direction (as shown in Figure ba) and are spaced apart sufficiently to just receive bridge 30, so that a surface-to-surface contact connection is made between surfaces 98 and 89 over a two-dimensional region when connection member 66 engages bridge 30, as described below. In order to B 3~Hd ~ Q I ' I~t0213 00 ' 6I 00-BZ-d38 permit connection member 66 to co4perate with bridge 30, front edge 80 of bridge 30 and inner surface 8d of bridge 64 should be more or less complimentary in shap~ to facilitate connection between connecting member 66 and bridge 30.
In use, to attach auxiliary unit 24 to primary unit 22, connection member 66 is slid in a rearward direction over bridge 30 so that surtaces fib fully engage surtaces 69. To remove the auxiliary unit, the unit is slid forward to disengage connection member 66 from bridge 30.
The two-dimensional, surface-to-surface contact connection '10 between surtaces 68 and 69, described above, permits a detachably secure connection to be made without the need far mechanical or magnetic retaining means. Friction between the close-fitting surfaces 88 and 69 causes the auxiliary lens unit to be retained on the primary unit. As one skilled in the art will understand, the width (ie. the distance in the lens-to-lens direotlon) of connection member 66 will determine the security and stablltty of the connection, with the widest possible connection member (Figures 1-4) being preferred. Referring to Figure 7, a narrower connection member 66 may also be used.
The surtaoe-to-surface contact area provided, as compared to the essentially point-to-point connection of the magnetic prior art such as U.S-Patent No. 8,053,611 to Ku, results in a more secure connection and, surprisingly, beneficially permits the bridge 30 thickness to be reduced signlflcantiy and, in some cases, by more than half. Thus connection member 66 is adapted to avoid a large, bulky bridge 30 resulting in a primary lens unit 22 that is aesthetically pleasing and, thus, much more marketable to the ever-fashion conscious consumer.
The surfaces 68 on connection member 66 are substantially parallel to one another in the rearward direction (see Figure 5a), although, in an alternate embodiment, surfaces 68 may be directed slightly toward one 5 3'JHd ' Q I = 140213 00 ' 6 L O0-AZ-d35 _g..
another In the rearward d(rection, as shown in Figure 5b. This embodiment permits connection 66 to apply a slight pressure on bridge 30 to ensure maximal contact between surfaces 68 and 69.
Ag shown in Figures Ba-6c, bridge 30 may have many shapes (when viewed face-on), such as rectangular (Figure 6a), curved (Figures 1 end 8b) or mutually concave (Figure 6c), provided that the surfaces 68 an connection member 66 correspond in shape to surtaces 69. Yet further shapes for bridge SO available to the creative mind are under'St04d to be within the scope of the present invention.
Referring again to Figure 1, an additional securing system may optionally be provided, such as a pair of side extension members or clips 70 extending rearwardly from an outer portion of rims 62 on auxiliary lens unit 24, as depicted in Figure 1 and known in the prior art. Clips 70 engage an outer portion of rims 28 on the primary lens unit 22 to provide additional stability between the auxiliary lens unit 24 and the primary lens unit 22. Other clip designs are equally available, such as that disclosed in the applicants' co-pending Canadian Patent Application Na_ 2,291,918, incorporated herein by reference.
Tha eyeglass device 20 according to the present invention is thus improved over the prier art in that no Ivcking mechanical or magnetic connection is required to achieve a secure connection of an auxiliary len$
unit to a primary lens unit. The resulting sliding connection of the present invention is simple to operate, is not subject to wear or decay over time and permits a sleek and attractive bridg~ on the primary lens to be utilized, thus not sacrificing the attractiveness of the primary lens for functionality with a lesser-used accessory s~uoh as the auxiliary lens unit, It should be understood that what has been described are preferred embodiments of the invention. It should therefore ba apparent to persons skilled in the art that various modifications and adaptations of the 0I 3~Hd ~QI ~H0213 I0~66 00-6Z-d36 _7_ preferred ~mbadiments described herein are possible without departure from the present invention, the scope of which Is defined in the appended claims.
Far instance, it should be unde~rstoad that lenses 26, 60 may be supported without the provision of rims 2B, 62. In such cases, elements of the lens units 22, 24 are directly secured to tha lenses 26, f0 In a known manner using screw fastanars, glue, solder or welds. It is contemplated that the present invention may be readily adapted to such rimless lens units by connecting the Structural elements such as bridges 30 andlGr 64 and clips 70 dir~tly to the lenses as discussed above. Still other modifications will be apparent to those skilled in the art.
