Abstract

Abstract An accident warning and traffic guide system particularly useful during fog is installed along an edge of the road. It comprises guide posts spaced along the road edge and carrying a blinking warning light and a warning switch. A safety or cutout fuse is connected in the current supply circuit for each warning light, and the fuses are mechanically protected.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 132 words
An accident warning and traffic guide system along an edge of a road extending in a road section in a direction contrary to the direction of traffic, comprising 1. a plurality of guide posts spaced along the edge of the road in said road section, 2. a blinking warning light on each of the guide posts, the brilliance and frequency of blinking of the lights decreasing in the direction contrary to the traffic direction, e. a source of current and supply circuit connecting the current source to each of the warning lights, 4. a warning switch on each of the guide posts between the supply circuit and the warning light, 5. a safety or cutout fuse in the supply circuit for each warning light; and 6. mechanically secured boxes holding the fuses.
Claim 2
Dependent Claim 132 words
An accident warning and traffic guide system along an edge of a road extending in a road section in a direction contrary to the direction of traffic, comprising 1. a plurality of guide posts spaced along the edge of the road in said road section, 2. a blinking warning light on each of the guide posts, the brilliance and frequency of blinking of the lights decreasing in the direction contrary to the traffic direction, e. a source of current and supply circuit connecting the current source to each of the warning lights, 4. a warning switch on each of the guide posts between the supply circuit and the warning light, 5. a safety or cutout fuse in the supply circuit for each warning light; and 6. mechanically secured boxes holding the fuses.
Claim 3
Dependent Claim 46 words
a blinking warning light on each of the guide posts, the brilliance and frequency of blinking of the lights decreasing in the direction contrary to the traffic direction, e. a source of current and supply circuit connecting the current source to each of the warning lights,
Claim 4
Dependent Claim 46 words
a blinking warning light on each of the guide posts, the brilliance and frequency of blinking of the lights decreasing in the direction contrary to the traffic direction, e. a source of current and supply circuit connecting the current source to each of the warning lights,
Claim 5
Dependent Claim 122 words
The accident warning and traffic guide system of claim 1, wherein the current source is a low-voltage source comprising a first conductor and a second conductor of opposite polarity, each of the warning lights being connected to the first conductor of the low-voltage current source in parallel, the current supply circuit includes a third conductor, with the switches having one pole connected to the second conductor of the low-voltage current source and the other pole connected to the third conductor, and further comprising means arranged in the third conductor between the switch connections for producing a voltage drop, and a switching relay for each of the warning lights, each relay having a coil connected in parallel to the first and third conductors.
Claim 6
Dependent Claim 52 words
