20090272955 | TENSION GUARDRAIL TERMINAL - In accordance with a particular embodiment of the present invention, a terminal portion of a guardrail safety system includes a terminal portion of a guardrail beam having a downstream end and upstream end. The terminal portion of the guardrail beam slopes from a height appropriate for redirecting an errant vehicle to a height proximate the surface of the ground at an upstream end of the terminal portion. Support posts are installed adjacent a roadway in spaced apart relation to one another and are coupled to the terminal portion of the guardrail beam. A terminal support post is installed adjacent the roadway at an upstream end of the end terminal. The terminal support post couples to an upstream end of the terminal portion of the guardrail beam by a resistive, tensile coupling that maintains tension in the terminal portion of the guardrail beam. The resistive, tensile coupling is maintained between the terminal support post and the guardrail beam during an end-on or re-directive impact by a vehicle. However, the resistive, tensile coupling between the terminal support post and the guardrail beam is released during a reverse-direction impact. | 11-05-2009 |
20090272956 | GUARDRAIL SAFETY SYSTEM FOR DISSIPATING ENERGY TO DECELERATE THE IMPACTING VEHICLE - In accordance with a particular embodiment of the present invention, an end treatment of a guardrail safety system includes a terminal portion of a guardrail beam that has a downstream end and an upstream end. The terminal portion of the guardrail beam slopes from a first vertical height appropriate for redirecting an errant vehicle to a second vertical height proximate the surface of the ground at an upstream end of the terminal portion of the guardrail beam. A flattening portion forms a channel through which the terminal portion of the guardrail beam is disposed. A vertical dimension of the channel is greater at a downstream end of the flattening portion than at an upstream end of the flattening portion. An impact plate is connected to the flattening portion for engaging an impacting vehicle at an end of said guardrail beam. During an end-on impact, the impact plate and the flattening portion are advanced longitudinally along the guardrail in a downstream direction by the vehicle. The advancement of the impact plate and flattening portion dissipate energy to decelerate the impacting vehicle. As downstream portions of the guardrail beam are forced into the flattening portion, the guardrail is flattened vertically. | 11-05-2009 |
20100275515 | ENERGY ABSORBING SYSTEM - An energy absorbing system having a stanchion, a linearly extendable energy absorber coupled to the stanchion, a net coupled to the energy absorber, wherein the net transfers force to the energy absorber, and a securing mechanism that maintains tension between the net and the energy absorber until acted upon by tensile forces of at least a minimum threshold force, wherein at least a portion of the system is retractable into the ground. | 11-04-2010 |
20110057160 | Tension Guardrail Terminal - A terminal portion of a guardrail safety system includes a terminal portion of a guardrail beam having a downstream end and upstream end. The terminal portion of the guardrail beam slopes from a height appropriate for redirecting an errant vehicle to a height proximate the surface of the ground at an upstream end of the terminal portion. | 03-10-2011 |
20140234024 | SURFACE MOUNT WEDGE BARRIER - The present disclosure relates to a system including an anchor configured to be disposed within a foundation, wherein an upper side of the anchor is configured to be exposed at a surface of the foundation and a wedge-style anti-ram security barrier configured to mechanically couple to the anchor and mount to the surface of the foundation. | 08-21-2014 |
20150159333 | SURFACE MOUNT WEDGE BARRIER - The present disclosure relates to a system including an anchor configured to be disposed within a foundation, wherein an upper side of the anchor is configured to be exposed at a surface of the foundation and a wedge-style anti-ram security barrier configured to mechanically couple to the anchor and mount to the surface of the foundation. | 06-11-2015 |
20160060832 | MODULE FOR USE IN A CRASH BARRIER AND CRASH BARRIER - A module suitable for use in a crash barrier has a diaphragm with opposite first and second sides. First and second cellular foam blocks are coupled to the first and second sides of the diaphragm respectively. A wrap layer surrounds a periphery of the first and second cellular foam blocks. A sealant layer may be applied to the wrap layer. In one embodiment, the wrap layer is configured as a metal cover member. A crash barrier may be configured with one or more modules. A method of manufacturing a module includes adhering first and second cellular foam blocks to opposite sides of a diaphragm and wrapping a wrap layer around a periphery of the first and second cellular foam blocks. A transition rail may be connected between first and second crash barriers. | 03-03-2016 |
20160130775 | SINGLE ANCHOR TERMINAL - A single anchor terminal is provided for a roadside wire rope barrier. The single anchor terminal includes a release post, a brace, and an anchor base. The brace supports the release post in an upright position and extends from the release post to the anchor base. The brace has a first portion attached to the release post and a second portion coupled to the first portion with a release component. The anchor base includes a main post that supports the release post and a brace anchor that is coupled to the main post. | 05-12-2016 |
