  • Publication number: 20090279951
    Abstract: A Surface Mount Channelizer (40) for more efficiently absorbing impacts to a marker or sign used for demarking traffic lanes provides means for efficiently replacing a flexible shaft without detaching a mounting base from a lane surface. The apparatus comprises an upright marker (10) connected to a mounting base (18, 24), wherein the apparatus has means for providing free movement of marker (10) in any direction relative to mounting base (18, 24). The means for providing free movement comprises a flexible hinge (22), connecting marker (10) to mounting base (18, 24). Marker (10) is preferably comprised of a flexible material, and in combination with flexible hinge (22) is capable of a range of motion from upright to parallel with the ground 360° around said mounting base.

  • Patent number: 7597501
    Abstract: An energy absorbing terminal is described that is made up of a plurality of cells partially defined by cambered panels made of thermoplastic or another suitable material. The panels are supported upon rectangular frames. The cambered portion of the panels provides a predetermined point of flexure for each panel and, thus, allows for energy dissipation during a collision. The stiffness of the crash cushion may be varied by altering material thicknesses and diaphragm spacing. In operation, a vehicle colliding in an end-on manner with the upstream end of the energy absorbing terminal will cause each of the cambered panels to bend angularly at its point of flexure and, thus, cause the cells to collapse axially. The use of thermoplastic, such as polyethylene results in a reversible, self-restoring collapse for the terminal, meaning that the terminal is reusable after most collisions.

  • Patent number: 7597502
    Abstract: A block of compressible material, such as cellular concrete, provides compressive failure characteristics suitable for arresting travel of an aircraft (or other vehicle) overrunning a runway (or other surface). Relatively thin frangible material positioned above the block provides a stronger, more damage resistant surface, while still readily fracturing in an arresting incident. Intermediate material, such as a foam layer, positioned under the frangible material may be included to provide a protective cushioning effect by mitigating transmission of external phenomena forces to the block. A fastening configuration at least partially enclosing other portions of the arresting unit provides a stable unified composite, without destroying desired compressive failure characteristics of the unit. Arresting units may also include a bottom layer of material stronger than the block of compressible material and a sealant coating with water resistant properties.

  • Patent number: 7497640
    Abstract: A road safety barrier having four or more ropes 4-7 supported by posts 1-3 rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and follows a sinuous path between the posts. The ropes are tensioned against the posts and this gives rise to a combined frictional resistance to displacement of the ropes relative to each post along the length of the safety barrier. The structure of at least some of the posts and/or their mounting with respect to the ground defines a minimum bending yield strength in a direction along the length of the barrier. This minimum bending yield strength is greater than the bending moment resulting from the combined frictional resistance forces acting on the post.

An elongate tie bar 21 has a first end part connected to the anchor body (9) and a second end part releasably connected to the terminal (19) so that the elongate tie bar is in line with the terminal and the end portion (8) of the rope. The tie bar (21) reduces the risk of damage to the terminal (19) in the event of vehicular impact, and is easily replaceable. It also facilitates disengagement of the rope from the anchor body (9) if a vehicle becomes trapped 1o the end portion (8) of the rope during a collision.

  • Patent number: 7340854
    Abstract: An improved sign post assembly (10) for roadway use is provided wherein a sign post (12) includes a lower section (16) adapted for anchoring to the earth, a mating upper section (20) and a magnetic coupling assembly (24) for maintaining the sections during normal use while permitting breakaway of the upper section (20) when the host (10) is struck by a vehicle. Preferably, the coupling assembly (24) includes a magnetic body (26) and a corresponding component (28) which is magnetically attracted to the body (26). In order to cause breakaway in a predetermined direction, the coupling assembly (24) has mating surfaces for the body (26) and component (28) which are in a stairstep configuration.

  • Patent number: 7306397
    Abstract: An energy absorbing system with one or more energy absorbing assemblies is provided to reduce or eliminate severity of a collision between a moving vehicle and a roadside hazard. The energy absorbing system may be installed adjacent various roadside hazards or may be installed on highway service equipment. One end of the system may face oncoming traffic. A collision by a motor vehicle with a sled assembly may result in shredding or rupturing of portions of an energy absorbing element to dissipate energy from the vehicle collision.

  • Patent number: 7287930
    Abstract: A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle. The vehicle impact attenuator includes a shock absorber that deforms upon a collision by a vehicle to reduce the impact on the vehicle. A support is provided for the shock absorber and a holding portion holds the support (20A) in a vertical position in an installation area. The support has cuts made in it that upon application of a load equal to or exceeding a set value, fracture and function as a release mechanism to thereby release the support from being held in a vertical position in the installation area. The support is deformable by a load less than the set value.

  • Patent number: 7249910
    Abstract: A delineator includes a post having a bottom portion and a stem extending from the bottom portion. At least a portion of the post is moveable in a lateral direction between an at-rest position and an impact position. An anchor includes a top and an elongated receptacle. In one aspect, the stem is removably inserted in the receptacle and is moveable in a longitudinal direction between at least a first position and a second position relative to the receptacle as the flexible post is moved between the at-rest position and the impact position respectively. A first portion of the length of the stem is disposed in the receptacle when the stem is in the first position and a second portion of the length of the stem remains disposed in the receptacle when the stem is in the second position, wherein the first portion is greater than the second portion. Methods of removably retaining a boundary in a pathway and of installing a boundary in a pathway are also provided.

  • Patent number: 7210874
    Abstract: An energy absorbing system with one or more energy absorbing assemblies is provided to reduce or eliminate the severity of a collision between a moving motor vehicle and a roadside hazard. The energy absorbing system may be installed adjacent to a gore area and other relatively wide roadside hazards. One end of the system facing oncoming traffic is relatively narrow. The width at an opposite end of the system may be varied to accommodate relatively wide or large roadside hazards. A sled assembly may be provided with a cutter plate such that a collision by the motor vehicle with the sled assembly will result in the cutter plate tearing or ripping the energy absorbing element to dissipate energy from the motor vehicle collision.
