Abstract

A traffic sign add-on includes a front layer made of a first fabric having one or more reflective sections and a back layer made of a second fabric having a slot extending along a long dimension of the back layer from a bottom end to a top end with a zipper in the slot. The zipper is capable of closing to seal the slot. The front layer and the back layer are connected along peripheral longitudinal edges and form a substantially flat form. Further, the front layer and the back layer are configured to accommodate a circumference of a pole of a traffic sign coaxially with the long dimension of the back layer and are substantially co-dimensional when the slot is sealed with the zipper.

First claim

1 : A traffic sign add-on, comprising:
a front layer, wherein the front layer is made of a first fabric, wherein the first fabric has one or more reflective sections, a back layer, wherein the back layer is made of a second fabric, wherein the back layer has a slot extending along a long dimension of the back layer from a bottom end to a top end wherein a zipper is disposed in the slot, wherein the zipper is capable of closing to seal the slot, wherein the front layer and the back layer are connected along peripheral longitudinal edges and form a substantially flat form, wherein the front layer and the back layer are configured to accommodate a circumference of a pole of a traffic sign coaxially with the long dimension of the back layer, wherein peripheral latitudinal edges at the bottom end and the top end of the front layer and back layer are at least partially unconnected, wherein the front layer and the back layer are substantially co-dimensional when the slot is sealed with the zipper.

2 : The traffic sign add-on of claim 1 , wherein the front layer has a fabric lining made of a third fabric and the third fabric has a same length and a same width of that of the front layer.

3 : The traffic sign add-on of claim 2 , wherein the fabric lining is located between the first fabric and the second fabric.

4 : The traffic sign add-on of claim 2 , wherein the fabric lining is attached to the front layer with stitches.

5 : The traffic sign add-on of claim 2 , wherein the third fabric is the first fabric without the one or more reflective sections.

6 : The traffic sign add-on of claim 1 , wherein the first fabric comprises a first material and a second material, wherein the second material is configured in a rectangular form and is located in a middle of a front face of the first material.

7 : The traffic sign add-on of claim 6 , wherein the second material extends along a long dimension of the first material from a bottom end to a top end.

8 : The traffic sign add-on of claim 1 , wherein the one or more reflective sections are in accordance with EN ISO 20471.

9 : The traffic sign add-on of claim 1 , wherein the front layer and the back layer are separated by one or more add-on structures which are located perpendicular to the pole of the traffic sign.

10 : The traffic sign add-on of claim 9 , wherein the one or more add-on structures are cube-shaped and located at a top end and bottom end of the pole of the traffic sign.

11 : The traffic sign add-on of claim 9 , wherein the front layer and the back layer are connected along the peripheral longitudinal edges and to the one or more add-on structures to form a rectangular shape.

12 : The traffic sign add-on of claim 1 , wherein:
the front layer of the first fabric comprises at least four pieces of the first fabric, wherein the back layer comprises at least two pieces of the second fabric, wherein a first piece of the at least two pieces of the second fabric is attached to a second piece of the at least two pieces of the second fabric by the zipper, wherein the at least two pieces of the second fabric are attached to one or more of the at least four pieces of the first fabric.

13 : The traffic sign add-on of claim 12 , wherein the at least two pieces of the second fabric are attached to one or more of the at least four pieces of the first fabric by a hook and loop fastener along one or more edges.

14 : The traffic sign add-on of claim 1 , further comprising:
one or more light-emitting diodes, wherein the front layer and the back layer have a hook and loop fastener along one or more edges, wherein the one or more light-emitting diodes are attached to the hook and loop fastener, wherein the one or more light-emitting diodes protrude from the hook and loop fastener to an outside of the traffic sign add-on.

15 : The traffic sign add-on of claim 14 , including a photovoltaic panel attached to the light-emitting diodes.

16 : The traffic sign add-on of claim 14 , wherein:
the back layer is covered with a flexible photovoltaic cell on an outer surface and a flexible battery on an inner surface, wherein the flexible photovoltaic cell charges the flexible battery, and wherein the flexible battery provides power for the one or more light-emitting diodes.

17 : A method of traffic accident reduction, comprising:
placing the traffic sign add-on of claim 14 on the pole of the traffic sign, wherein the front layer is an outermost layer and facing an outside of the pole, wherein the traffic sign is a speed limit sign or a stop sign, and illuminating the light-emitting diodes.

18 : The method of claim 17 , wherein the light-emitting diodes are continuously illuminated.

19 : The method of claim 17 , wherein the traffic sign add-on extends at least 90% the length of the pole of the traffic sign.

20 : The traffic sign add-on of claim 1 , wherein a constriction device is located at a top end of the front layer and the back layer and a bottom end of the front layer and the back layer, wherein the constriction device holds the traffic sign add-on in place.
