ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to clip-on glasses, and more particularly to clip-on glasses that are adapted to connect to a front of regular glasses, including rimless glasses.
The connection of a pair of additional glasses to the front of another pair of regular glasses is currently popular among young men because lenses of the additionally connected glasses may have a design different from that of the regular glasses to easily change the appearance and/or function of the regular glasses.
FIG. 1
shows a pair of conventional glasses
2
for additionally connected to the front of a pair of regular glasses
1
. For the glasses
2
to connected to the regular glasses
1
, two magnets
12
are separately set in and flush with a front of the regular glasses
1
near two outer sides of two rims
11
of the glasses
1
, and two connecting arms
21
are separately extended from two sides of the additional glasses
2
with two magnets
22
separately set in and flushing with rear surfaces of the connecting arms
21
. By positioning the additional glasses
2
in front of the regular glasses
1
and aligning the magnets
22
on the connecting arms
21
with the magnets
12
at two outer sides of the rims
11
, the magnets
12
and
22
attract one another to associate the glasses
1
with the glasses
2
.
The above-described structure for connecting the additional glasses
2
to the regular glasses
1
has the following disadvantages that need to be improved:
1. Since the magnets
12
are flush with the front of the regular glasses
1
and the magnets
22
are flush with rear surfaces of the connecting arms
21
of the additional glasses
2
, the glasses
1
,
2
are simply magnetically connected to each other through the flat contact of the magnets
12
with the magnets
22
. The two pairs of glasses
1
,
2
tend to separate from each other under an external force adversely applied on the glasses.
2. The additional glasses
2
are connected to the regular glasses
1
through the two pairs of flatly contacted magnets
12
and
22
. In the event two temples
13
of the regular glasses
1
are outward stretched or otherwise deformed when the glasses
1
are worn by a user, it is possible a distance between the two magnets
12
changes to cause disalignment of the magnets
12
and
22
from one another, and accordingly, undesired separation of the additional glasses
2
from the regular glasses
1
.
3. For the magnets
12
,
22
to be set in and flush with the front of the glasses
1
and the rear surface of the glasses
2
, respectively, the glasses
1
,
2
must have frames of a certain thickness large enough to receive the magnets
12
,
22
, and the shape of portions of the glasses
1
,
2
at where they contact with one another must be flat. All these conditions largely restrict the design of the glasses
2
to only very narrow scope, making the glasses
1
and
2
heavy and monotonous in appearance.
4. The above-mentioned additional glasses
2
could not be used with rimless glasses that have lenses directly connected to temples of the glasses. As mentioned above, the temples tend to deform when the glasses are worn by a user and easily cause disalignment of the magnets
12
and
22
from one another.
It is therefore tried by the inventor to develop improved glasses for additionally connected to regular glasses in a very simple but reliable manner to eliminate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a pair of clip-on glasses that could be easily and reliably connected to a front of a pair of regular glasses without the risk of easily separating from the regular glasses.
Another object of the present invention is to provide a pair of clip-on glasses that could be connected to a front of a pair of regular glasses having any type of frame, including rimless glasses.
To achieve the above and other objects, the clip-on glasses of the present invention mainly include at least two rimmed or rimless lenses and a bridge connecting the two lenses to each other. The bridge is provided at a back side with upper and lower clips, each of the two clips is provided at an inner side near a rear edge thereof with at least one magnet to normally magnetically attract the two clips to contact with each other at the rear edges. At least one of the two clips is pivotally movable relative to another clip to facilitate easy separation of the two magnetically contacted clips from each other. The clip-on glasses could be firmly connected to a front of a pair of regular glasses by clamping a bridge of the regular glasses between the upper and lower clips behind the bridge of the clip-on glasses and by closing the upper and lower clips with the mutually attracted magnets to enclose the bridge of the regular glasses in the closed upper and lower clips of the clip-on glasses. The clip-on glasses may be connected to all types of glasses, including rimless glasses.
