The present invention discloses a semi rigid joint for flexibly joining various links/structures. The said semi rigid joint comprises plurality of joining elements wherein each said joining element supporting at one end at least one joining component and at its other end having a magnetic connector such that the two adjacent placed joining elements facing said respective magnetic connectors under magnetic attraction of respective magnetic connectors provide a magnetic joint to connect together the components carried at its other ends. A flexible spring means is also proved in cooperation with the magnetic joint to allow bending at said magnetic joint under any external impact/force exceeding the magnetic attraction of the magnets and on release of said external impact/force rejoining the joints under restored magnetic attraction.

A joint for a signpost having a first segment and a second segment is provided. The joint includes a first cap for the first segment, a second cap for the second segment, and a multi-directional hinge coupleable between the first cap and the second cap. The hinge is pivotable to facilitate lateral movement of the first cap relative to the second cap.

A roadway safety device includes one or more spacers which engage a falling arm attached to a sign so as to lift the sign relative to a structure on which a housing bracket attached to the arm rests. The roadway safety device may include a spacer which dampens the fall of the arm and which holds the arm at an upward angle to make the sign more visible to drivers.

A post foundation system is provided. The system has a shaft with a helical disk attached to one end and a post support attached to the other end. The helical disk drives the shaft into the ground as a rotational force is applied to the shaft. A fin section is rotatably coupled about the shaft between its first and second ends. The fin section can have one or more fins extending outwardly from the shaft. The fin section engages the ground to stabilize the post foundation system as the shaft of the post foundation system is driven into the ground.
