Abstract

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.

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.

Claims (6)

1. A method of attaching sunglass frames to eyeglass frames, by the use of a special attached to or molded into the eye glass frame an elongated slot aria just behind the nose bridge on each side of said bridge and extending below the bridge.
Slots can be closed in, or safety loops must be installed to prevent accidental removal of the arms.

2. This slot aria as described in claim 1 is to have guide arias above the slots which incorporate the width of the said frames follow the contour of the eyeglass frame and lead to the slots, this guide enables easy installation of the friction arms.

3. The friction arms mentioned in claim 2 have a latch aria located at the bottom of the arms that latch's under the bottom of these slots. The arms bend at an angel at the top of the slots and seat against the upper safety loops. Then continue on, leading too and bend at a 90-degree angle and enter the friction spring and bridge housing.

4. The Friction spring and bridge housing mentioned in claim 3 allow the sunglasses to be flipped up or down. The friction arms become the friction spring and bend over the Sunglasses Bridge and apply continuos presser to allow the sunglasses to be placed and held at any angle from 0 to 180 degrees. Two groves on the sunglass frames round nose-bridge fit into slots in the spring and bridge housing to prevent end play.

5. The said spring mentioned in claim 4 is held at the back of the housing by a special clip and is bent over the nose bridge by the pressure plate and two compression screws which also hold the housing shut. The spring configuration is unique to this invention.

6. The sunglasses frames mentioned in claim 4 have a non-slip surfaces applied at 7=8 & 10=11 O'clock on one side and 1=2 & 4=5 O'clock on the other. This allows fore easy positioning of the sunglasses with left or right hand. The coating also acts as a cushion for the sunglass frame against the eyeglass frame.
