Abstract
Abstract Plastic traffic barricade is very resistant to damage from being struck by vehicles. When struck by a vehicle, the barricade generally collapses and falls under the vehicle resulting in no damage to the vehicle. The front and rear panels formed by rotational casting are hollow and include legs and cross-bars which are adapted to be filled with ballast such as sand to resist tipping over. The panels are self hinged to each other below an integral vertical reflector panel to further increase their stability. An integrally molded container for a flasher helps to protect the vehicle and the flasher in the event of a collision and also protects the flasher against unauthorized removal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A traffic barricade comprising first and second hollow resilient plastic panel members, each panel member comprising a pair of hollow leg portions and at least one hollow cross-bar portion integrally joined to said leg portions, a vertical panel portion adapted to receive warning indicia on at least one side thereof, said vertical panel portion being integrally formed with at least one of said panel members so as to extend above said leg portions, hinge means integrally formed on each of said panel members, the hinge means on each of said panel members being adapted to cooperate with the hinge means on the other to permit said panels to be pivoted relative to each other between a storage position and a use position, stop means on each of said panels for limiting the relative pivotal movement of said panels and defining said use position, and aperture means in each of said panels for permitting ballast to be placed in said hollow legs and cross-bar portions.
Claim 2
Dependent Claim
164 words
A traffic barricade comprising first and second hollow resilient plastic panel members, each panel member comprising a pair of hollow leg portions and at least one hollow cross-bar portion integrally joined to said leg portions, a vertical panel portion adapted to receive warning indicia on at least one side thereof, said vertical panel portion being integrally formed with at least one of said panel members so as to extend above said leg portions, hinge means integrally formed on each of said panel members, the hinge means on each of said panel members being adapted to cooperate with the hinge means on the other to permit said panels to be pivoted relative to each other between a storage position and a use position, stop means on each of said panels for limiting the relative pivotal movement of said panels and defining said use position, and aperture means in each of said panels for permitting ballast to be placed in said hollow legs and cross-bar portions.
Claim 3
Dependent Claim
86 words
The traffic barricade of claim 1 wherein said vertical panel portion is formed in said first panel member at a location above said hinge means, said vertical panel portion being formed at an angle relative to the plane of the leg portions and connecting the upper ends of said leg portions whereby said vertical panel portion will be positioned in a vertical plane when the legs of said first and second panel members are spread apart at an angle to the vertical in their use position.
Claim 4
Dependent Claim
40 words
The traffic barricade of claim 2 wherein said second panel member is shorter than said first panel member and of a generally H-shaped configuration, said second panel member having its hinge means located adjacent the upper end of its legs.
Claim 5
Dependent Claim
35 words
The traffic barricade of claim 1 wherein an open topped housing for receiving and surrounding the base of an auxiliary flasher unit is integrally formed at at least one end of said vertical panel portion.
Claim 6
Dependent Claim
26 words
The traffic barricade of claim 4 wherein said open topped housing comprises the aperture means through which ballast can be placed in said first panel member.
Claim 7
Dependent Claim
50 words
The traffic barricade of claim 1 wherein said aperture means in said second panel is located at the top of at least one of said leg portions so as to be covered by one of the leg portions on said first panel when said barricade is in its use position.
Claim 8
Dependent Claim
22 words
The traffic barricade of claim 1 wherein said vertical panel portion is recessed in the area adapted to receive said warning indicia.
Claim 9
Dependent Claim
19 words
The traffic barricade of claim 1 wherein said hollow cross-bar portions have recessed surfaces adapted to receive warning indicia.
Claim 10
Dependent Claim
30 words
The traffic barricade of claim 1 wherein the center of gravity of the barricade when unballasted is less than one-half the distance to the top of the vertical panel portion.
