Specification
Clip & Flip SunglassNisor System
This invention relates to an almost invisible method of fastening and
unfastening sunglass
frames to eyeglass frames. By the use of elongated slots molded into the back
of the
eyeglass frames, on each side of the nose bridge and just above the nose
rests.
Guides above the slots that follow the contour of the eyeglass frame lead into
them.
Friction spring arms insert into the slots and lock the sunglasses in place.
The friction arms
are an extension of a spring that applies pressure to the sunglass nose bridge
inside the spring
and bridge housing and allows the sunglasses to flip up and or serve as a
visor by staying in
any position the user desires from 0 to 180 degrees.
2. The present methods of attaching sunglasses to eyeglasses are many, but all
have their
problems. The old clip on type that squeeze the lenses, although they flip up
and down they only
lock in these two said positions. They also move around and scratch the
lenses. Another type uses
magnets to hold the sunglasses in place. If you go in doors you can't flip
them up, you have to
take them off and put them in there case, hold on to them, put them in your
pocket or set them
down and forget them. The user is also exposed to magnetic fields in close
proximity to their eyes
every time they use them. Other types use hooks on the top, bottom, sides or
where ever to hold
them on. These types are more difficult to install/remove and have the same
problems as the
magnetic ones when going in doors or needing maximum vision.
These fore mentioned types do not serve as a visor.
3. With the invention of the Clip & Flip Sunglass/visor System these problems
are solved.
The friction arm slots witch are molded into or fastened to the eye glass
frames. Hold the friction
arms in place witch in turn hold the sunglasses in place. Allowing fore one to
easily install or
remove the sunglasses.
The Clip & Flip Sunglass/visor System allow one to flip their sunglasses up
when they go in
doors, or need maximum vision.
This system serves as a visor and will stay in any position from 0 to 180
degrees, whatever angle
the user selects.
Also the user is not in close proximity to magnetic fields when using them. A
non-slip surfaces
can be installed at 7=8 & 10=11 O'clock on the left side and 1=2 & 4=5 on the
right to assist in
the positioning of the sunglasses, by the right or left hand.

2. Sunglasses nose bridge l.Smm dia.
3. Friction arms .65mm diameter and from 3A to end of arm at bottom of latch
#l0.is 6mm, and
Smm to top of latch Distance between arms should be 3mm to 6mm greater than
the distance
between the friction arm slots.
3A. Arms bend and continue on to housing. Length and angels of this portion of
the arms
3A to 3B depend on the distance between the friction arm slots. Witch is
determined by the length of the eyeglass nose-bridge. A 2cm wide nose bridge
wile
maintaining the 4mm clearance of the spring & bridge housing above the nose
-bridge. The length of this portion of the arms from 3A to 3B is l .cm. 3A has
an
inside angle of 140 Degrees.
3B. Arm's bend at 90 degrees and enter housing. Angle of horizontal plane 40

i 3. Two .Smm x 2.mm screws apply pressure to spring compression plate and
also hold
housing shut.
14. Two .2mm deep x .6mm wide groove's in nose bridge fit into slots in
housing to prevent
endplay.
