Abstract

A plurality of signboards on a pair of legs are pivotally connected to a base and held in a vertical position by shear pins adapted to shear upon a predetermined impact force being directed against the signboards from either direction thereby allowing the legs to pivot to a collapsed horizontal position.

Claims

1. A collapsible portable barricade comprising:

a base frame lying approximately in a single plane and having a forward frame member, a rearward frame member and opposite side frame members;

each of said side frame members having a bracket attached thereto intermediate the opposite ends thereof;

a pair of leg members having upper and lower ends;

at least one display cross member extending transversely of and interconnecting said leg members;

hinge means including a pivot pin connecting each of said leg members to one of said brackets adjacent said lower ends of said leg members for pivotal movement about a horizontal hinge axis, said legs being pivotal approximately 180°

from a first horizontal position to a vertical position to a second horizontal position,

said legs having locking holes extending therethrough and located in spaced relation to said hinge axis,

said brackets each having a first hole, a second hole and a third hole positioned to register with said locking holes when said leg members are in said first horizontal position, said vertical position and said second horizontal position, respectively,

a shear pin extending through said locking holes and one of said first, second and third holes, said shear pin being removable to permit movement of said leg members between said first horizontal, vertical and second horizontal positions, and

said shear pin being adapted to shear in response to a predetermined impact force being directed to said leg, so that said legs will pivot to one of said horizontal positions in response to said impact force.

2. The structure of claim 1 wherein said legs in said horizontal positions are flat against and parallel to said base.

3. The structure of claim 1 wherein said shear pin is smaller in diameter than said pivot pin whereby pivoting occurs about the axis of said pivot pin and said shear pin is sheared upon said impact force being directed against said legs.

4. The structure of claim 1 wherein said legs are of metal tube material and said legs are interconnected by wood signboards.

5. The structure of claim 1 wherein said legs are capable of pivoting towards either of said opposite ends of said base and said legs are positioned midway between said opposite ends of said base.
