Abstract
Abstract A traffic barricade of the portable type comprising first and second vertically disposed frame members having a pair of vertically disposed and horizontally spaced barricade panels secured thereto and extending therebetween. First and second legs are pivotally secured at their upper ends to the first frame member intermediate the length thereof and third and fourth legs are pivotally secured at their upper ends to the second frame member intermediate the length thereof. A channel-shaped member is positioned between the upper ends of the legs and the respective frame members which limits the pivotal movement of the legs with respect to the frame members and causes the frame members to be vertically disposed when the barricade is in the operative position. The barricade may be folded from the operative position to a substantially flat position.
