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.

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.

The invention relates to a connecting device for a pole of the support structure for road equipment, including a hollow drum, having a circular, elliptical, or polygonal section, comprising a first end for anchoring to the foundation, a second end for fixing to a lower end of the pole, and a central part with a wall portion configured for deforming in a controlled manner when an impact force acts on the pole, such that the lower end of the pole is displaced upwards and twisted in the direction of the impact force. A support structure for road equipment including the connecting device is also an object of the invention.

One or more hinging fence post assemblies comprising a section of hinging fence posts that when met with lateral pressure will release or break a support mechanism allowing the posts to go from a generally vertical position to a generally horizontal position on the ground via a hinge mechanism. The pressure at which the support mechanism releases or breaks, and the posts hinge down, is adjustable. The lower base post will stay in place in the ground, while the longer upper post will have hinged from a generally vertical position to a generally horizontal position on the ground allowing the fence materials to remain attached to the upper post. When desired, the upper post can be quickly raised into its upright position.
