  • Patent number: 8545126
    Abstract: The portable traffic safety barrier is formed of plastic or recycled rubber, and has a narrower upper portion and wider cap atop the upper portion to form a mushroom-shaped cross section. Elongate passages are formed through each barrier section, and a spring is installed in at least one passage to connect the barriers resiliently to one another end-to-end. Another passage contains a flexible coiled electrical cord to provide power for lighting the barrier, the lighting being installed atop the barrier sections. The springs and coiled cord allow connected barriers to separate in the event of impact, while still maintaining the integrity of the assembly and lighting. Wheels may be provided beneath the barrier sections to allow lateral repositioning. Two or more rows of barriers may be arranged laterally, and the resulting gap between barriers serves as a planter box or for the installation of signage.

  • Patent number: 8517349
    Abstract: Devices and methods for supporting guardrail terminal installations that incorporate safety end treatments such as the GET and the SRT. Preferred embodiments are described wherein guardrail terminal installations are primarily anchored to the ground using weak support posts that are preferably made of metal. The ends of the guardrail installation are secured to the ground using breakaway posts. In operation, the weak posts permit the central portion of the guardrail installation to contain and redirect the vehicle during a lateral collision to the rail member. The anchorage provided by the breakaway end posts helps prevent the guardrail from being excessively displaced, thus preventing the impacting vehicle from breaking through the guardrail. In operation, guardrail terminal assemblies constructed in accordance with the present invention provide an improved support system for the rail member which is more forgiving than conventional strong post anchorages, thereby providing an improvement in safety.

A fastener extends through the load transfer member and shock absorber, and secures the bollard, load transfer member and shock absorber to a ground surface. The load transfer member adjoins the bollard so as to be disposed between the shock absorber and the bollard, and the load transfer member is configured so that when an impact force is applied to the bollard, the force is transferred from the bollard to the shock absorber via the load transfer member. The deflection is absorbed by the shock absorber so that the anchor remains undeformed and the ground remains undamaged. Moreover, due to the resilience of the shock absorber, the bollard and load transfer member are returned to a normal, upright orientation upon withdrawal of the impact load.

In general, the hydraulic circuit includes a normal-UP and normal-DOWN section, an emergency-UP section, and an external pressure relief valve. In order to automatically provide corrective action in the event of an overpressure condition, the external pressure relief valve is connected to the hydraulic circuit. Upon occurrence of condition that causes the hydraulic fluid pressure to exceed a predetermined value, hydraulic fluid is released through the pressure relief valve to maintain the pressure at or below the predetermined value.

  • Patent number: 8328461
    Abstract: Increased resistance to displacement of a barrier or barrier sections thereof in response to a lateral force without anchoring or bolting barrier sections together is achieved by providing an attachment arrangement near the top of an end of barrier sections which is capable of carrying a tensile force and developing that tensile force using a tightening bolt/nut arrangement located at deflection stops at lower corners of the barrier sections to develop a compressive force. The barrier sections are thus rigidly attached together such that a lateral force applied to one or more barrier sections is partially transferred to additional attached barrier sections effectively increasing the mass against which the lateral force is applied. The tightening bolt/nut arrangements are retained by and are captive to the respective barrier sections when barrier sections are disassembled from each other.

    Abstract: The first product is Composite Guardrail Post (CGP). CGP is designed overcome all these drawbacks by substituting standard timber posts with metal jacket composite posts. The second product is Composite Floor Joist (CFI). The current invention (CFI) is similar to TJI in concept, but uses all composite material for both flanges and webs. Also, the connections between flange and web are much stronger, enabling the development of composite actions to the fullest extent.

  • Patent number: 8317162
    Abstract: A road rail comprises tubular posts (1; 20) to be anchored in the ground and a rail profile (2; 21) to be attached to the posts. The rail profile has a substantially closed cross-section but is open downwards for lowering onto the posts. The rail profile is supported on each post by a support member (5; 24) carried by lower edges of opposed cutouts (4; 23) in the post. At least one locking member (7; 26) inside the rail profile provides locking between the post and the rail profile by engagement on one hand with the rail profile and on the other hand with an upper edge of each post cutout (4; 23) by a locking tongue (10; 27) of the locking member.

  • Publication number: 20120280193
    Abstract: In a terminal arrangement for a road rail with a rail profile (2) a terminal guiding device (10) is movable along the road rail under the influence of kinetic energy from a vehicle hitting the terminal guiding device. A terminal profile (8), constituting a prolongation of the rail profile (2), extends within the terminal guiding device (10) obliquely down to a ground anchor (4), where it is attached. Means (13) for deforming the terminal profile (8) and eventually the rail profile (2) and thus for absorbing kinetic energy are provided in the terminal guiding device (10).
