A self-powered delineator includes a wind-powered rotatable module; a first piezoelectric energy generator module for generating electrical energy; a second piezoelectric energy generator module for generating electrical energy; and a light-emitter. The wind-powered rotatable module includes one or more first magnets spacedly arranged around a rotation shaft. The first piezoelectric energy generator module includes one or more first piezoelectric elements, and one or more second magnets disposed on the at least one first piezoelectric element. The second piezoelectric energy generator module includes at least one elastic base extending radially from a fixed shaft in a cantilever manner; and at least one second piezoelectric element on the at least one elastic base.

A plowtector system for extending a snow marker pole over a residential curb. The plowtector system reduces the chance of damage to a curb and/or snow plow when plowing is necessary. A snow marker pole placed within the plowtector system reaches over where the curb starts so that the snow plow operator has a clearer indication of how far to the side they can travel. Should the plowtector system be struck by a snow plow, the system can twist from side to side, reducing the amount of damage that may be caused by such action. The integral components of the plowtector system keep the snow marker in a level position, and bypass the possibility of the snow marker becoming lodged in snow or ice.

A structure of a sign pole is provided. The sign pole includes a tubular member that has a predetermined outer diameter, a predetermined inner diameter, and a predetermined thickness. In a state in which the sign pole is embedded in a ground, the sign pole includes a reinforcement portion having a thickness different from the predetermined thickness while maintaining the predetermined outer diameter in a first range from a first position equal to or lower than a level of a ground surface to a second position located a predetermined distance above the level of the ground surface. The reinforcement portion has a thickness larger than the predetermined thickness.

The present invention relates to posts, carriages, methods of manufacturing the components and their assembly into a barrier. The invention also includes a Z post attachment includes an attachment tab 8.016 and end engagement flange 8.024, 8.026 adapted to engage the end of the post. The arrangement can include a delineator 8.030 which is skew in relation to the tab 8.016, so as to provide reflector faces 8.032 which face oncoming traffic.

A roadside delineator device that includes a breakaway shear pin feature that allows the upper portion of the device to break away from the lower portion of the device during a vehicular accident. The upper and lower halves can be reconnected by replacing the broken shear pins.

A roadside delineator device that includes a breakaway shear pin feature that allows the upper portion of the device to break away from the lower portion of the device during a vehicular accident. The upper and lower halves can be reconnected by replacing the broken shear pins. This allows the re-use of components and saves time and money by not having to install a completely new roadside delineator device.

A mounting system for driveway marker poles includes a mount body, a coil spring and a ground spike. The mount body includes an upper end with an opening for receiving a driveway marker, the opening leading to an internal axial passage. The mount body includes a lower portion sized to slidingly engage within an upper segment of the coil spring with an interference to retain the mount body to the coil spring. The ground spike includes a threaded upper end with an exterior thread configured to threadedly engage into a lower segment of the coil spring. Systems without a coil spring are also described.
