Patent number: 8328461Abstract: 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.Type: GrantFiled: September 28, 2010Date of Patent: December 11, 2012Inventor: Rodney I.

Publication number: 20120280193Abstract: 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).Type: ApplicationFiled: November 10, 2010Publication date: November 8, 2012Applicant: AB VARMFORZINKNINGInventor: Anders Welandson

Patent number: 8276886Abstract: A combined guardrail and cable safety system is disclosed. In one aspect, a safety barrier incorporating the teachings of the present disclosure may include a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables may be releasably engaged with and supported by the cable posts. The cable posts and the at least two cables may cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts may also spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A box beam guardrail beam may be attached to the plurality of guardrail posts. The at least two cables may operably extend from the cable posts to engage respective cable anchor brackets attached to the box beam guardrail beam.Type: GrantFiled: June 29, 2011Date of Patent: October 2, 2012Assignee: Trinity Industries, Inc.Inventors: Don J. Gripne, Charles R. Norton, Elzard A. Sikkema, Brian E. Smith

Patent number: 8277143Abstract: Anti-ram systems according to embodiments of the invention comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base. An anti-ram system according to embodiments of the invention may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram system also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.Type: GrantFiled: May 12, 2010Date of Patent: October 2, 2012Assignee: RSA Protective Technology, LLCInventors: Richard S. Adler, John Crawford
