Abstract
Abstract A Type I Traffic Barricade is described having a reflective panel mounted between a pair of leg supports. Each leg support has two legs pivotally secured together at an upper end and in a spaced relationship by a pair of brackets on opposing sides of the leg support. The brackets are placed into slots formed on an underside of the reflective panel and, with the legs spread for the widest possible stance at their lower end, the upper end is biased against the reflective panel for complete and stable vertical and lateral support, while allowing easy set-up and knock down with minimum space requirements for storage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A collapsible traffic barricade assembly for the control of traffic, the identification of traffic lanes and the like, having a center panel with opposing end portions and two supporting leg assemblies, at least one slot formed of a certain width in each end portion of said center panel, each of said slots extending inward from a lower edge of said center panel, each of said supporting leg assemblies comprising two leg members, said leg members being joined by a bracket at an upper end, said bracket having a certain maximum thickness, said maximum thickness being equal to or slightly less than said certain slot width, said bracket being attached to each leg member for pivotal movement of each of said leg members, said bracket spacing said leg members from one another to allow insertion of said bracket into said slot whereby said center panel is supported by said leg assemblies in a substantially horizontal manner, the lower ends of said leg members being spread to bias said upper end against said center panel, whereby the substantial equivalency in size of said slot and said bracket thickness in combination with the bias of said upper end against the center panel contributes to great lateral stability while said barricade assembly is easily collapsible and said leg members are capable of pivoting to a substantially flat position on collision or disassembly.
Claim 2
Dependent Claim
