Abstract

Abstract An indicator structure including one or more lengths of perforated tubing arranged in a desired configuration, such as a traffic barricade. The tubing contains one or more flash lamps which produce a light-tunnel effect during operation to provide a high intensity warning or indicating signal in a pre-selected configuration of flash illumination via the tubing perforations.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 53 words
An indicator structure for signaling or warning applications comprising a length of perforated metal tubing, an arc discharge flashlamp with a xenon gas fill disposed in alignment with said length of tubing for radiating an intense burst of light through the interior of said tubing during operation, and means for operating said flashlamp.
Claim 2
Dependent Claim 53 words
An indicator structure for signaling or warning applications comprising a length of perforated metal tubing, an arc discharge flashlamp with a xenon gas fill disposed in alignment with said length of tubing for radiating an intense burst of light through the interior of said tubing during operation, and means for operating said flashlamp.
Claim 3
Dependent Claim 13 words
The structure of claim 1 wherein said flashlamp is disposed within said tubing.
Claim 4
Dependent Claim 18 words
The structure of claim 2 wherein said flashlamp is disposed at one end of said length of tubing.
Claim 5
Dependent Claim 16 words
The structure of claim 1 wherein said tubing has perforations uniformly distributed throughout the length thereof.
Claim 6
Dependent Claim 12 words
The structure of claim 4 wherein said tubing has a rectangular cross-section.
Claim 7
Dependent Claim 16 words
The structure of claim 5 wherein said perforations are located on all sides of said tubing.
Claim 8
Dependent Claim 15 words
The structure of claim 4 wherein said perforations are equal-sized circular holes in said tubing.
Claim 9
Dependent Claim 41 words
The structure of claim 3 further including a second arc discharge flash lamp disposed in said length of tubing at the opposite end from that at which said first-mentioned flash lamp is disposed, and means for operating said second flash lamp.
Claim 10
Dependent Claim 21 words
The structure of claim 8 wherein said means for operating said first and second lamps provides flashing thereof in alternate sequence.
Claim 11
Dependent Claim 63 words
The structure of claim 1 further including a plurality of perforated tubing members configured as legs and attached to each end of said first-mentioned length of perforated tubing for forming a traffic barricade, said flash lamp being disposed at one end of said first-mentioned length of tubing in alignment with the leg members of tubing attached thereat for radiating light therethrough during operation.
Claim 12
Dependent Claim 89 words
The structure of claim 10 further includes a second arc discharge flash lamp disposed in said first-mentioned length of tubing at the opposite end from that at which said first-mentioned flash lamp is disposed, said second flash lamp being in alignment with the leg members of tubing attached to the end at which said second lamp is disposed for radiating light through said last-mentioned leg members during operation, and means for operating said second flash lamp to provide flashing thereof in alternate sequence with respect to said first-mentioned lamp.
Claim 13
Dependent Claim 24 words
The structure of claim 1 further including a second length of perforated tubing attached to said first-mentioned length of tubing in an X-shaped configuration.
Claim 14
Dependent Claim 61 words
The structure of claim 12 wherein said flash lamp is disposed at one end of said first-mentioned length of tubing, and further including a second arc discharge flash lamp disposed at one end of said second length of tubing, and means for operating said second flash lamp to provide alternate flashing thereof in alternate sequence with respect to said first-mentioned lamp.
Claim 15
Dependent Claim 31 words
The structure of claim 1 wherein said length of perforated tubing has the configuration of an arrow, and said flash lamp is disposed at one end of said length of tubing.
Claim 16
Dependent Claim 54 words
The structure of claim 14 further including a second arc discharge flash lamp disposed in said length of tubing at the opposite end from that at which said first-mentioned flash lamp is disposed, and means for operating said second flash lamp to provide flashing thereof in alternate sequence with respect to said first-mentioned lamp.
Claim 17
Dependent Claim 27 words
The structure of claim 1 further including a coating on the interior surface of said length of perforated tubing for increasing the reflectivity of said interior surface.
