Abstract: A glarefoil assembly for mounting to a median barrier which divides opposing lanes of a highway system and operates to reduce the glare of headlights from oncoming vehicles. The glarefoil assembly includes a plurality of glare blades which are rigidly attached to a base section in an appropriate light-blocking orientation. The base section is rigidly mounted to the top of the median barrier at opposing ends, thereby preserving some latitude for vibrational movement within this base section. By virtue of the rigid attachment between the glare blades and base section, along with the compatible elastic moduli of these materials, the glarefoil assembly operates as an integral unit providing energy transfer from the glare blades into the base section. Such energy transfer prevents material failure developed by pulsating winds which typically arise from passing traffic.

Abstract: A yieldable roadway signing and delineating apparatus is disclosed. A standard is positioned at a safe distance from the roadway to avoid snowplows, mowers and other errant vehicles. A horizontal moveable arm extends toward the roadway and carries a sign at its free end, thus placing the sign or delineator at the required position near the roadway for viewing by passing vehicle operators. Means for moveably retaining the arm in a desired position, permitting its deflection by pressure, and returning the arm to the desired position upon release of pressure are provided. Thus, the sign can yield to pressure from snowplow and mower attachments with a minimum or no damage to the sign. A delayed action mechanism is provided wherein a sealed fluid filled canister is eccentrically positioned around a shaft to which a gate is pivotally attached.

Abstract: A sign serving as a deterrent to unauthorized parking is mounted on a post which is resiliently supported by a base in a normal vertical position and is adapted to be deflected into an inclined position by the car bumper when overriding the base in driving head-in into the parking space. The base has a vertical wall which guides the post in returning from the inclined to the normal vertical position preventing rearward deflection and has an open front shaped to permit the forward deflection of the post through a predetermined horizontal angle. An axial helical tension spring for a tubular post or a spring biased pivot for a channel shaped post connects the respective post to the base for the resilient deflectability.A wire slide-guard is mounted along the post spaced from the sign to engage the car bumper and any protruding portions of the undercarriage for smooth passage therealong to facilitate the deflection and prevent the sign from locking thereon when the car backs out of the parking space.

Abstract: A self-erecting sign post has a rigid but frangible section along its length at its lower end and a coextensive helical spring circumjacent the rigid section and interconnecting the separated post portions, the assembly being such that the frangible section constitutes a zone of weakness which will break before the remainder of the sign post bends upon impact, the spring being operative to restore the sign post to its erect position until the frangible section can be replaced.

An elongated staff element has its lower portion mounted non-rotatably in the blind bore and has a plurality of wind vane elements secured fixedly thereto. The wind vane elements extend radially outwardly from the staff element and are spaced equidistantly thereabout. Thus, in response to wind or other forces, the marking device will exhibit a tipping and rotating movement on its spherical lower surface.

Abstract: A self-erecting highway guide post for insertion in the ground is constructed in the form of a resilient plastic channel having a substantially flat center surface flanked on either side by a pair of flat side portions which are joined at an obtuse angle to the center portion by curved surfaces. A second, arcuately cross-sectioned channel is attached by fasteners through the center portions of each channel to the rear of the first channel. The rear, concave surface of the arcuate channel is directed toward the rear surface of the first channel and lies within its side portions. Such a configuration results in a self-erecting highway guide post when one end is imbedded in the ground to denote the margin of a highway. When the post is struck the curved portions flatten allowing the post to bend when run over by a vehicle and to recurve once the vehicle passes to re-erect the post.
