A vertical panel system comprises a vertical panel having a panel with opposing first and second panel surfaces and a base edge. The system further comprises a base having a slot for engaging the base edge of the panel. An aperture is disposed in the panel in proximity to the base edge, which is of sufficient size to receive a foot of a user, for assisting in the engagement of the panel and the base. The base for the vertical panel system comprises a center zone fabricated of vulcanized rubber, and an outer zone fabricated of recycled rubber. The slot is disposed in the center zone. Thus, the combination solves a need to be environmentally responsible and cost effective by recycling rubber which would otherwise fill our landfills, yet provides increased durability by using virgin vulcanized rubber in the zone of the base which includes the engagement slot.

A truck mounted attenuator (TMA) is constructed to minimize length during use in a horizontal position and height in a vertical transport position, as well as to minimize wind resistance and buffeting at highway speeds. A modular construction is employed, so that only damaged portions of the TMA can be removed and replaced in the field after a vehicle impact. The TMA comprises a plurality of outwardly curved tubular structural members which are designed to buckle upon application to the TMA of forces resulting from vehicular impact. The rigid tubes buckle at a high initial force, then proceed to crush at a lower force once the sides have buckled outwardly sufficiently to protect vehicle occupants during the critical first two feet of travel after impact. This design also provides increased protection for errant vehicles which impact the TMA device from an angle (i.e. 'coffin corner' impact).

An inertial barrier system comprises inertial barriers formed of two modules, each of them being differently sized and being adapted to stack one upon the other. An interlocking geometry on each of the mating ends of modules assists in obtaining a secure stacking arrangement. One of the two modules functions as a container, facing upwardly so that its volumetric capacity is available for filling by a particulate ballasting material. The lower module functions only as a pedestal for the support of the upper module. The upper module is advantageously fillable to different predetermined levels, so that the apparatus, comprising the joined lower and upper modules, is capable of functioning as differently weighted barrier systems.

Molded ribs are provided for use in connection with traffic channeling devices, such as drums, which employ external ballasting collars, such as molded rings or truck tire rings. The ribs are disposed at spaced intervals near the bottom of the external wall of the drum, for improving contact between the drum wall and the internal diameter of the ballasting collar, in order to eliminate undesirable separation of the drum and collar during ordinary use, and to prevent inadvertent rotation of the drum relative to the collar.

In a traffic channeling device, a molded rib for attachment to an exterior surface of a bottom wall of a drum for inhibiting the drum from rotating relative to a rubber ballasting collar. The rib comprises an exterior surface for contact with the rubber ballasting collar, a back surface for contact with the bottom wall of the traffic channeling device, and a thickness between the exterior and back surfaces. In aspects of the device, the one or more molded ribs may be attached to the bottom wall exterior surface in a latitudinal arc of less than 180&deg;. In further aspects of the device, locator pins radially extending from the bottom wall exterior surface complement cavities in the back surface of the molded rib. In additional aspects of the device, fasteners, such as screws, attach the molded ribs to the device such that the fasteners do not extend past a wall inside surface, thereby inhibiting marring of drum walls during stacking of the drums. In further aspects of the device, the drum and the ribs are unitarily molded.

A sign stand has a mast with a flexible upper portion. The flexible upper portion of the mast inhibits the mast from piercing a windshield of a vehicle when the sign stand is struck by the vehicle. The sign stand may have a sign mounted on the mast flexible upper portion. Additionally, a top end of the mast flexible upper portion extends beyond a top edge of the sign. The mast flexible upper portion may have other items attached to it, such as a flag holder, a light mounting bracket, a light, or sign mounting brackets. The sign mounted to the flexible upper mast may be metal, such as aluminum, composite materials, or fabric. The mast also has a lower portion that is connected to a support stand. The mast lower portion may be flexibly connected to the support stand. The mast may be made up of two or more parts. The mast may be telescopic. The upper and lower portions of the mast may be in a telescopic relationship. The flexible upper portion of the mast may telescope from an interior space of the mast lower portion. The relationship may be other than telescopic and at least a portion of the flexible mast upper portion may be disposed inside the mast lower portion. The two portions of the mast may be mechanically attached.
