Abstract: A collapsible and deployable sign system includes a support tube and a sliding member longitudinally slidable on the support tube. A handle is rotatably connected to the support tube and rotatably linked to the sliding member such that rotation of the handle slidably displaces the sliding member with respect to the support tube. A bracket assembly is fixed to the support tube. At least one scissoring assembly including first and second scissoring links is rotatably connected together by a rotational fastener. The first scissoring link is rotatably connected to the bracket assembly and separately to a corner brace member. The second scissoring link is rotatably connected to the sliding member and separately to the corner brace member. Handle rotation moves the sliding member toward the bracket assembly moving the corner brace member from a stowed condition proximate the support tube away from the support tube to a deployed condition.

Abstract: A warning flag deployment system includes a mount having a closed bracket having a contact wall. A rod positioning member has a stowed retention wall and a deployed retention wall angularly oriented to the stowed retention wall. An open bracket has an open bracket leg and a standoff leg spacing the open bracket leg from a surface of the mount defining plane. A flag support rod is connected to the mount and is rotatable between a stowed condition and a deployed condition. The stowed condition has the flag support rod positioned between the contact wall and the stowed retention wall of the rod positioning member. The deployed condition has the flag support rod positioned between the rod positioning member deployed retention wall and the standoff leg and at least partially in a cavity defined between the plane and the open bracket leg.
