TITLE: AURILIARY LENSES FOR EYEGLASSES
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to auxiliary lenses,
05 and more particularly to auxiliary lenses for
eyeglasses.
2. Description of the Prior Art
A typical spectacle frame having an attachable
one-piece slide-on rim is disclosed in US Patent No.
4,070,103 to Meeker. In Meeker, a spectacle frame
includes a magnetic material secured to the peripheral
portion thereof for facilitating attachment of the
auxiliary lens rim cover to the spectacle frame. The
lens rim cover also includes a magnetic strip for
engaging with the magnetic material of the spectacle
f rame .
Another typical eyeglasses are disclosed in US
Patent No. 5,416,537 to Sadler and comprise first
magnetic members secured to the temporal portions of
the frames and second magnetic members secured to the
corresponding temporal portions of the auxiliary
lenses.
In both of the eyeglasses, the auxiliary lenses
are simply attached to the frames by magnetic materials
and have no supporting members for preventing the
auxiliary lenses from moving downward relative to the
frames such that the auxiliary lenses may easily move


CA 02180714 2001-10-05

- 2 -
downward relative to the frames and may be easily
disengaged from the frames when the users conduct
jogging or jumping exercises. In addition, the magnetic
materials are embedded in the frames of the primary
05 lenses and of the auxiliary lenses such that the frames
should be excavated with four or more cavities for
engaging with the magnetic members and such that the
strength of the frames is greatly decreased.
The present invention has arisen to mitigate
and/or obviate the afore-described disadvantages of the
conventional spectacle frames.
SUMMARY OF THE INVENTION
The primary objective of the present invention is
to provide auxiliary lenses which may be stably secured
and supported on the frames.
In accordance with one aspect of the invention,
there is provided an eyeglass device comprising a
primary spectacle frame for supporting primary lenses
therein, the primary spectacle frame including two side
portions each having an extension extended therefrom
for pivotally coupling a leg means thereto, the primary
spectacle frame including two rear and side portions
each having a projection secured thereto, the primary
spectacle frame including an upper portion, a pair of
first magnetic members secured in the projections
respectively, an auxiliary spectacle frame for
supporting auxiliary lenses therein, the auxiliary

spectacle frame including two side portions each having
an arm extended therefrom for extending over- and for
engaging with the upper portion of the primary
spectacle frame, and a pair of second magnetic members
05 secured to the arms respectively for engaging with the
first magnetic members of the primary spectacle frame
so as to secure the auxiliary spectacle frame to the
primary spectacle frame. The arms are engaged with and
supported on the upper portion of the primary spectacle
frame so as to allow the auxiliary spectacle frame to
be stably supported on the primary spectacle frame and
so as to prevent the auxiliary spectacle frame from
moving downward relative to and so as to prevent the
auxiliary spectacle frame from being disengaged from
the primary spectacle frame.
The projections and the first magnetic members are
arranged lower than the upper portion of the primary
spectacle frame, the second magnetic members are
extended downward toward the projections for hooking on
the primary spectacle frame so as to further secure the
auxiliary spectacle frame to the primary spectacle
frame. The auxiliary spectacle frame may be prevented
from disengaging from the primary spectacle frame.
Further objectives and advantages of the present
invention will become apparent from a careful reading
of a detailed description provided hereinbelow, with
apr~ropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, and initially to FIGS.
1 to 4, an eyeglass device in accordance with the
present invention comprises a primary spectacle frame
10 for supporting primary lenses therein. The primary
spectacle frame 10 includes two side portions each
having an extension 11 extended rearward therefrom for
pivotally coupling a leg 12 thereto. The primary
spectacle frame 10 includes two projections 13 secured
to the rear and side portions thereof for supporting
magnetic members 14 therein. An auxiliary spectacle
frame 20 is provided for supporting the auxiliary
lenses therein and includes two side portions each
having an arm 21 extended rearward therefrom for
extending over and for engaging with the upper portion


CA 02180714 2001-10-05

- 5 -
of the primary spectacle frame 10 (FIGS. 5 and 6). The
auxiliary spectacle frame 20 also includes two magnetic
members 22 secured to the arms 21 thereof for engaging
with the magnetic members 14 of the primary spectacle
05 frame 10 such that the auxiliary spectacle frame 20 may
be stably supported on the primary spectacle frame 10,
best shown in FIGS. 5 and 6.
It is to be noted that the arms 21 are engaged
with and are supported on the upper portion of the
primary spectacle frame 10 such that the auxiliary
spectacle frame 20 may be stably supported and secured
to the primary spectacle frame 10. The auxiliary
spectacle frame 20 will not move downward relative to
the primary spectacle frame and will not be easily
disengaged from the primary spectacle frame when the
users conduct jogging or jumping exercises.
It is further to be noted that the projections 13
and the magnetic members 14 are secured to the primary
spectacle frame 10 and the magnetic members 22 are
secured in the arms 21. The magnetic members 14, 22 are
not embedded in the frames 10, 20 such that the frames
10, 20 are not required to be formed with cavities
therein and such that the strength of the frames 10, 20
will not be decreased.
Referring next to FIG. 7, it is preferable that
the projections 13 and the magnetic members 14 are
located slightly lower than the upper portion of the


CA 02180714 2001-10-05
primary spectacle frame 10; and the end portions of the arms 21 and/or the
magnetic
members 22 are slightly extended downward toward the projections 13 such that
the arms
21 and the magnetic members 22 may hook on the primary spectacle frame 10 and
such
that the auxiliary spectacle frame 20 may further be stably supported and
secured to the
primary spectacle frame 10. In one embodiment, as shown in FIG. 7, magnetic
members
14 and 22 are not in contact with each other; magnetic members 14 and 22 lie
in a plane
that is substantially horizontal when the eyeglass device is worn and are
engaged with,
but not supported on, each other. Instead, the arm 21 securing the magnetic
member 22
is supported on an upper side portion of the primary spectacle frame 10. As
shown in
FIG. 7, the upper side portion can be an upper part of the side portion
securing the
projection 13.
Accordingly, the eyeglass device in accordance with present invention includes
an
auxiliary spectacle frame that may be stably secured to the primary spectacle
frame and
will not move downward relative to the primary spectacle frame and will not be
easily
disengaged from the primary spectacle frame when the users conduct jogging or
jumping
exercises. In addition, the magnetic members are not embedded in the frames
such that
the strength of the frames will not be decreased.
Although this invention has been described with a certain degree of
particularity,
it is to be understood that the present disclosure has been made by way of
example only
and that numerous changes in the detailed construction and the combination and
arrangement of parts may be restored to without departing from the spirit and
scope of
the invention as hereinafter claimed.
