Abstract
The present invention teaches a sunglasses clip-on device which enables a user to securely place an auxiliary sunglass lens easily and expeditiously. The device enables the sunglass lens to be inserted onto the bridge of a spectacle snugly through mechanical means, thus avoiding the need to use the more costly and weighty traditional magnetic means or the unsightly clamping means.
The clip-on device of the invention comprises a proximal-end wall member extending vertically and in parallel with a distal-end wall member. The proximal-end wall member and the distal-end wall member are integrally connected in the middle section to form an inverted "U" shape. The distal-end wall member has a width shorter than the width of the bridge of the spectacle. There is provided at least two mechanical fastener means located at the two outboard ends of the proximal-end wall member for receiving auxiliary sunglass lenses. There is also provided at least two first protrusions means provided on the proximal-end wall member and projecting towards the at least two second protrusions means provided on the distal-end wall member in order to create a void, whereby the thickness of the voids is bigger than the thickness of the spectacle bridge for securely engaging the sunglasses clip-on device onto the bridge.

Description
SUNGLASSES CLIP-ON DEVICE
FIELD OF THE INVENTION
[0001] The present invention relates to the field of sunglasses clip-on devices for attaching sunglass lenses to a pair of spectacle thereon by mechanically inserting the device having the sunglass lenses onto the bridge of the spectacle.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[0001] The present invention relates to the field of sunglasses clip-on devices for attaching sunglass lenses to a pair of spectacle thereon by mechanically inserting the device having the sunglass lenses onto the bridge of the spectacle.
BACKGROUND OF THE INVENTION
[0002] Sunglasses clip-on devices have been known for quite some time. It is desirable for the clip-on sunglasses to be quickly and easily attached and removed from the spectacle so that the user can selectively engage or disengage the clip-on sunglasses when needed.
[0003] Traditionally, there are a number of devices that have been used to attach clip-on sunglasses to spectacle. Examples of the traditional clip-on sunglasses devices include those using magnetic force to fasten the frame of the sunglass lenses to the frame of the spectacle, or those using a flip-over style biasing clamp to secure the sunglass lenses to the bridge of the spectacle. With the flip-over style clamp, a user can "flip" the sunglass lenses skyward when the sunglass function is not required.
[0004] There are many disadvantages associated with the magnetic clip-ons and flip-over clamps.
The magnetic clip-ons are expensive and add weight to the spectacle which, in turn, creates discomfort to the user. While the flip-over clamps are not as weighty, the generally conspicuous and unsightly clamping mechanism takes away the aesthetic effect of the sunglass lens.
The magnetic clip-ons are expensive and add weight to the spectacle which, in turn, creates discomfort to the user. While the flip-over clamps are not as weighty, the generally conspicuous and unsightly clamping mechanism takes away the aesthetic effect of the sunglass lens.
[0005] In view of the disadvantages of the prior art clip-on devices, it is desirable to provide a sunglasses clip-on device which is both easy to use, inexpensive to manufacture and also enhances the aesthetic of the sunglass lenses and, at the same time, minimizing the weight burden of the add-on sunglass lenses by having a light weight sunglasses clip-on device.
[0006] The present invention addresses the foregoing shortcomings of the prior art sunglasses clip-on devices.
SUMMARY OF THE INVENTION

[0007] According to one aspect of the invention, it provides a sunglasses clip-on device for releasably engaging an auxiliary sunglass onto the bridge of a spectacle which comprises a proximal-end wall member extending vertically and in parallel with a distal-end wall member.
The proximal-end wall member and the distal-end wall member are integrally connected in the middle section to form an inverted "U" shape. The distal-end wall member has a width shorter than the width of the bridge of the spectacle. There is provided at least two mechanical fastener means located at the two outboard ends of the proximal-end wall member for receiving auxiliary sunglass lenses. There is also provided at least two first protrusions means provided on the proximal-end wall member and projecting towards the at least two second protrusions means provided on the distal-end wall member in order to create a void, whereby the thickness of the voids is bigger than the thickness of the spectacle bridge for securely engaging the sunglasses clip-on device onto the bridge.
According to another aspect of the invention, it provides a sunglasses clip-on device for releasably engaging an auxiliary sunglass onto a bridge of a spectacle which comprises a first spectacle-facing wall member, a second spectacle-facing wall member and a bridge-facing wall member. The device provides at least two mechanical fastener means at each of the outboard ends of the first and second spectacle-facing wall members for receiving auxiliary sunglass lenses. There is an inverted "U" shape void joining the inboard end of the first spectacle-facing wall member and another inverted "U" shape void joining the inboard end of the second spectacle-facing wall member at the two lateral ends of the bridge-facing wall member to form a notch in each of the inverted "U" shape voids, whereby the thickness of the notches is bigger than that of the spectacle bridge for securely engaging the sunglasses clip-on device onto the bridge.

DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE INVENTION
[0024] The sunglasses clip-on devices of the present invention will be described with reference to the drawings disclosed herein.
[0025] FIG. 1 is a bottom view of the sunglasses clip-on device 10 in accordance with a preferred embodiment of the present invention. When the orientation "bottom view" is used in the description herein, it is meant that the viewer is looking into the distal protrusions 101 and proximal protrusions 102 provided on the distal-end wall member 103 and proximal-end wall member 104, respectively. With this "bottom view" orientation, the viewer is also able to see the two sunglass lens rivets 105 disposed at each outboard end of the proximal-end wall member 104.
[0026] FIG. 2 is a top view of the sunglasses clip-on device 10 in accordance with the preferred embodiment of the present invention. When the orientation "top view" is used in the description herein, it is meant that the viewer is viewing the clip-on device from the top and that is also how the device will sit on the bridge of the spectacle when in use. With this "top view" orientation, the view is unable to see the distal protrusions 101 or the proximal protrusions 102 provided on the distal-end wall member 103 and proximal-end wall member 104. However, the viewer is still able to see the two sunglass lens rivets 105 disposed at each outboard ends of the clip-on device 10.
[0027] FIG. 3 is a front view of the sunglasses clip-on device 10 in accordance with the preferred embodiment of the present invention. By "front", it is meant that the viewer is looking at the clip-on device 10 away from the user. This also means that the proximal-end wall member 104 is closer to the viewer while the distal-end wall member 103 is further away from the viewer.
By the same token, the distal-end wall member 103 is facing the user. With this "front view"
orientation, the viewer is unable to see any of the distal protrusions 101, proximal protrusions 102 or rivet 105. The viewer clearly sees the proximal-end wall member 104 and, depending on the shape of the clip-on device 10, perhaps a small portion of the distal-end wall member 103 (as shown).
By the same token, the distal-end wall member 103 is facing the user. With this "front view"
orientation, the viewer is unable to see any of the distal protrusions 101, proximal protrusions 102 or rivet 105. The viewer clearly sees the proximal-end wall member 104 and, depending on the shape of the clip-on device 10, perhaps a small portion of the distal-end wall member 103 (as shown).
[0028] FIG. 4 is a rear view of the sunglasses clip-on device 10 in accordance with the preferred embodiment of the present invention. This is the opposite view of FIG. 3. As in FIG. 3, with this "rear view" orientation, the viewer is unable to see neither the distal protrusions 101 nor the proximal protrusions 102. However, the rivets 105 are clearly visible. The viewer can see the full distal-end wall member 103 but not the full proximal-end wall member 104, except the two outboard ends where rivets 105 are positioned.
[0029] Referring to FIGS. 1 to 4 and viewing from the top down, the clip-on device 10 takes on an inverted U-shape. The two sides of the inverted "U" are defined by a distal-end wall member 103 and proximal-end wall member 104. Proximal-end wall member 104 is symmetrically longer than distal-end wall member 103 in order to provide for the rivets 105 to attach the sunglass lens 60 at each of the outboard ends of the proximal-end wall member 104. Besides the rivets 105, at least two proximal protrusions 102 are provided on the proximal-end wall member 104. These proximal protrusions 102 work in cooperation with the distal protrusions 101 to form a tight and snugly fit onto the bridge of the wearer's spectacle 70.
[0030] As can be seen from FIGS. 1 to 4, the distal-end wall member 103 and the proximal-end "
wall member 104 are symmetrical and, preferably, matching in their geometrical shape. For example, if the distal-end is concave, it is preferred that the proximal-end is, correspondingly, concave in shape. Moreover, the distal-end wall member 103 is in the middle portion of the clip-on device 10 and its width must be shorter, albeit very slightly, than the bridge 701 of the spectacle 70. The reason is that the width of the bridge 701 defines the width of the distal-end wall member 103 since the latter must be able to be engaged onto the inside of bridge 701.
wall member 104 are symmetrical and, preferably, matching in their geometrical shape. For example, if the distal-end is concave, it is preferred that the proximal-end is, correspondingly, concave in shape. Moreover, the distal-end wall member 103 is in the middle portion of the clip-on device 10 and its width must be shorter, albeit very slightly, than the bridge 701 of the spectacle 70. The reason is that the width of the bridge 701 defines the width of the distal-end wall member 103 since the latter must be able to be engaged onto the inside of bridge 701.
[0031] The width of the middle portion of the proximal-end wall member 104 generally corresponds to the width of the distal-end wall member 103.
[0032] This "middle" portion on the clip-on device 10 is where the clipping mechanism takes place ¨ by cooperative clamping efforts provided by the distal protrusions 101 and proximal protrusions 102, such that when the device 10 is being inserted onto the bridge 701 of the spectacle 70, the distal protrusions 101 are urging against the distal side 703 of the bridge while, at the same time, the proximal protrusions 102 are urging against the proximal side 702 of the bridge.
[0033] Under this clipping mechanism, in order to produce the best tight fit, the dimension of the void 106 between the distal and proximal protrusions should be bigger, albeit very slightly, than the thickness of the bridge 701 of the spectacle 70. On the other hand, the precise location of the distal and proximal protrusions are not critical, so long as the distal protrusions 101 and proximal protrusions 102 are more or less evenly spaced apart within the distal-end wall member 103 and proximal-end wall member 104, respectively. Preferably and as shown in FIGS.
1 to 4, the proximal protrusions 102 are spaced further apart than the distal protrusions 101.
1 to 4, the proximal protrusions 102 are spaced further apart than the distal protrusions 101.
[0034] In order to provide a tight and snugly fit and to prevent or minimize any rattling of the clip-on device 10 while sitting on the bridge 701 of the spectacle 70, it is preferred that at least two distal protrusions 101 are provided to work cooperatively with at least two proximal protrusions 102.
_
_
[0035] Optionally, the distal and proximal protrusions can be made of resilient and/or flexible materials such that these protrusions are slightly bendable. It is to be noted that the protrusions 101 and 102 are integrated as part of the sunglasses clip-on device 10 to form a one-piece uni-body. It is also to be noted that the specific shape of the protrusions 101 and 102 is not important. For example, it can be cylindrical, square, diamond or triangular in shape.
[0036] The auxiliary sunglass lenses 60 can be fastened to the clip-on device 10 by inserting the rivets 105 through the lens apertures 601 by using conventional methods, such as to compress the bulb of the rivets 105 against the lenses 60 (as shown in FIG. 6).
[0037] FIGS. 7 to 9 show the different views of the clip-on device 10 of the instant invention being attached to a spectacle 70.
[0038] Depending on the style of the bridge 701 of the spectacle 70 and/or the style of the spectacle 70 itself, the shape of the clip-on device 10 and the curvatures of the distal-end wall member 103 and proximal-end wall member 104 can be modified. FIG. 10 shows another embodiment of the clip-on device 20 in which the middle bottom portion of the inverted "U" is convex in design. On the other hand, FIG. 11 shows a further embodiment of the clip-on device 30 in which not only the middle bottom portion of the inverted "U" is concave in design, it also rises "above" the proximal-end wall member 104.
[0039] FIGS. 12A and 12B illustrate additional embodiments of the clip-on device 40. Referring to FIG. 12A, instead of creating a void 106 between the distal and proximal protrusions, clip-on device 40 utilizes two notches 401 for inserting the clip-on device 40 onto the bridge 701 of the spectacle 70. In order to provide for a tight and snugly fit, the dimension of the width of the notches 401 should correspond and be just very slightly bigger than the thickness of the bridge 701 of the spectacle 70.
[0040] FIG. 12B illustrates the clip-on device 40 with bendable means embedded in the proximal-end wall member to promote bendability of the device 40. A metal stripe 402 is shown thereon.
[0041] FIG. 13 illustrates clip-on device 40 being inserted and fits snugly on bridge 701 of the spectacle 70.
[0042] The sunglasses clip-on device 10 can be made from any plastic injection materials.
Preferably, the device 10 is made from polyflex material. Also preferably, the device 10 is made from plastic injection materials which are stretchable and/or bendable.
