Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A tuck 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).

Abstract: 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°. 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.

Abstract: A sign stand has a mast with a flexible upper portion.

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.

Abstract: A safety delineator is provided which includes a conical body portion to which is attached one or more vertical panels. A new and improved handle feature permits easy and comfortable full hand gripping of the delineator and also prevents sticking and jamming together of a plurality of the delineators when they are stacked. The delineators may be stacked without removing the vertical panels, since each vertical panel is particularly designed to wrap around the conical body portion to which it is attached as another vertical delineator slides over it.

Abstract: A vertical panel system has a vertical panel and a base. The vertical panel has one or more panels. Each panel has opposing first and second panel surfaces and a plurality of edges, wherein the plurality of edges has a base edge. A tab extends from the first panel base edge and terminates at a tab bottom edge. The tab has two opposing side surfaces extending between two opposing side edges. At least one of the tab side surfaces has a tab groove extending from the tab bottom edge and towards the first panel base edge.

Abstract: Flag holders that are simple in design and relatively inexpensive to manufacture are disclosed. These flag holders secure flag arms to reinforcing battens of highway signs without unnecessary bulk, weight, and complexity. A flag holder includes a flag arm bracket having a generally U-shaped body with two opposing edges. The U-shaped body wraps around a frame member, such as a reinforcing batten, of the highway sign, to thereby align the flag arm bracket with the frame member. An aperture in the flag arm bracket accommodates a shaft, such as a bolt. The shaft passes through both the aperture of the flag arm bracket and also through an aperture in the frame member of the highway sign. The bolt secures the flag arm bracket to the frame member. The flag arm bracket further includes an attachment portion for attaching at least one flag arm to the flag arm bracket.

Abstract: A lifting ring assembly is designed for lifting barrels that have at least a partial circumferential radial extension above an outer diameter. The lifting ring comprises a split ring and a cross brace. The split ring comprises two half ring segments having mutually attachable ends. The inner diameter of the split ring is smaller than the outer diameter of the partial circumferential radial extension. The cross brace comprises first and second rigid arms having top ends and bottom ends. The top ends are mutually pivotally connected by a pivoting mechanism. The bottom ends are fixedly connected to a midpoint of the half ring segments, respectively, such that the cross brace is perpendicularly oriented to the split ring and the rigid arms pivot in a vertical plane. The lifting ring may be modified to lift with a fork lift truck with a cable loop that extends from the pivoting mechanism.

Abstract: An energy absorbing guardrail crash attenuator system comprises a row of two or more compressible sections comprising left and right curved, metal side panels. The row of compressible sections extends in an axial direction from a front end and terminates in a back end that is engagable with a rigid backup. When the row is impacted by a vehicle in the axial direction, the compressible sections bend outwardly and absorb energy. When the row is impacted in a direction that is off of the axial direction, the row redirects the vehicle so as not to hit the "coffin corner" of the rigid backup. The front ends of the left and right metal panels are flexibly joined while the back ends are pivotly joined to the rearwardly adjacent section. The panels may have panel bending modifications for facilitating the axial compression of the sections. The row may have an axial movement guide to restrict lateral movement of the row of compressible sections.
