Advance warning traffic safety device
First Claim
1. An advance warning traffic safety device comprising:
- a support structure having a base portion constructed for disposing said support structure in a displaceable, generally free standing position adjacent a vehicle traffic path from which the support structure is displaceable upon a collision therewith by an errant vehicle which has strayed from the traffic path;
an audible alarm means mounted in said support structure; and
means mounted in said support structure for activating the audible alarm means in response to a lateral displacing movement of said support structure by the errant vehicle, the audible alarm means being operable to broadcast an alarm to warn persons down road of the traffic safety device of the errant vehicle.

Abstract
The present invention provides an advance warning traffic safety device for warning pedestrians, members of a road work crew, and other persons adjacent a road that a vehicle has strayed from the proper traffic path on the road and may endanger such persons. The advance warning safety device provides an audible alarm which serves as an advance warning to such persons downroad of the traffic safety device. The traffic safety device includes a pressurized fluid container for supplying compressed air to a plurality of horns in response to a vehicle collision with the traffic safety device. An initiator mechanism for initiating the audible alarm includes a frangible gas cap which prevents release of the compressed air to the horns until broken by a plunger-type component, which is moved into glass or other breakable materials breaking contact with the cap by a pendulum device which pivots in response to displacement of the traffic safety device from its generally free standing position adjacent the road in response to a vehicle collision with the traffic safety device.

16. An advance warning traffic safety device comprising:
-
a support structure having a base portion constructed for disposing said support structure in a displaceable traffic path from which the support structure is displaceable upon collision therewith by an errant vehicle which has strayed from the traffic path; a horn mounted in said support structure for broadcasting an audible alarm to warn persons down road of the traffic safety device of an errant vehicle collision with the traffic safety device; a container mounted in said support structure having pressurized gaseous fluid therein and an outlet for release therethrough of pressurized gaseous fluid; a gaseous fluid conduit assembly mounted in said support structure for guiding pressurized gaseous fluid which has been released from the container to the horn to thereby produce an audible alarm; a frangible cap sealingly disposed on the container outlet for preventing release of pressurized gaseous fluid from the container into the conduit assembly; and an initiator device mounted in said support structure for breaking the frangible cap in response to a vehicle collision with the traffic safety device to thereby effect release of gaseous fluid to the horn for sounding an audible alarm.
