1. A traffic barricade support, comprising:
- a first leg having a first end and a second end, the leg having a triangular cross section including a narrow side, a wide side oriented substantially normal to the narrow side, and a hypotenuse side, and further forming a void creating a bore through the wide side and the hypotenuse side at the first end;
said first leg having a stop extending outwardly from the first end of the narrow side and having a contact surface;
a second leg substantially identical to the first;
a pivot, passing through the bore of the first leg and the bore of the second leg that pivotally joins the first leg to the second leg so that the hypotenuse side of the first leg is oriented towards the hypotenuse side of the second leg;
whereby when the first leg is pivotally moved from a closed position, where the first leg and the second leg are substantially parallel, to an open position, where the first leg and the second leg are at a relative angle, the stop of the first leg will engage the stop of the second leg and prevent any further increase of the relative angle of the first leg and the second leg.

Abstract
A sawhorse type of traffic barricade constructed from identical leg units. The legs are equipped with a stop to prevent them from opening beyond a predetermined point. The legs have the cross section of a right triangle, allowing the hypotenuse sides of the legs to nest within each other. The legs may be equipped with complementary convex and concave portions to allow the barricades to be stacked securely atop one another by fitting the portions together.

11. A traffic barricade, comprising:
-
a first traffic barricade support, comprising;
a first leg having a first end and a second end, the leg having a triangular cross section including a narrow side, a wide side oriented substantially normally to the narrow side and a hypotenuse side and further forming a void creating a bore through the wide side and the hypotenuse side at the first end;
said first leg having a stop extending outwardly from the first end of the narrow side and having a contact surface;
a second leg substantially identical to the first; and
a pivot, passing through the bore of the first leg and the bore of the second leg that pivotally joins the first leg to the second leg so that the hypotenuse side of the first leg is oriented towards the hypotenuse side of the second leg, whereby when the first leg is pivotally removed from a closed position, where the first leg and the second leg are substantially parallel, to an open position, where the first leg and the second leg are at a relative angle, the stop of the first leg engages the stop of the second leg and prevents any further increase in the relative angle of the first leg and the second leg;
a second traffic barricade support, substantially identical to the first traffic barricade support; and
a panel, wherein the narrow side of a leg of the first traffic barricade support and the narrow side of a leg of the second traffic barricade support are attached to the same side of the panel. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for stacking traffic barricades, comprising the steps of:
-
a) orienting a first traffic barricade in a substantially horizontal position on a surface, said barricade comprising;
a first barricade support including a first leg having a first end and a second end, the leg having a triangular cross section including a narrow side, a wide side oriented substantially normally to the narrow side and a hypotenuse side and further forming a void creating a bore through the wide side and the hypotenuse side at the first end;
said first leg having a stop extending outwardly from the first end of the narrow side and having a contact surface;
a second leg substantially identical to the first;
a pivot, passing through the bore of the first leg and the bore of the second leg that pivotally joins the first leg to the second leg so that the hypotenuse side of the first leg is oriented towards the hypotenuse side of the second leg, whereby when the first leg is pivotally moved from a closed position, wherein the first leg and the second leg are substantially parallel, to an open position, wherein the first leg and the second leg are at a relative angle, the stop of the first leg engages the stop of the second leg and prevents any further increase in the relative angle of the first leg and the second leg;
a second traffic barricade support, substantially identical to the first traffic barricade support, and a panel, wherein the narrow side of a leg of the first traffic barricade support and the narrow side of a leg of the second traffic barricade support are attached to the same side of the panel; and
wherein a first portion of The narrow side of the first leg forms a convexly curved surface and a second portion of the narrow side of the first leg forms a concavely curved surface that is complementary in shape to the convexly curved surface of the first portion; and
b) placing a second traffic barricade substantially identical to the first traffic barricade on top of the first traffic barricade, such that at least one of the convexly curved surfaces of The second traffic barricade nests in at least one of the at least one of the concavely curved surfaces of the first traffic barricade.
