Problems solved by technology

Since the frame of the Leonhardt patent is held in its original position by bolts, which only respond to the force of the hinges in the middle, the opening of the hinges on opposite sides of the frame is therefore not coordinated with each other

Embodiment Construction

[0013] Referring now to the drawings, FIG. 1 shows a traffic impact attenuator frame 10 including first, second and third cross members 12 , 14 , 16 spaced apart along a longitudinal centerline L. As shown in FIG. In this example the cross members are shown as frames, but in alternative embodiments could form solid panels. In general, the cross member may be of any form, including a single piece and an assembly formed of multiple parts.

[0014] The first and second transverse members 12, 14 are connected to each other by a first side member 18 and a second side member 20, the first side member is located on the first side of the longitudinal centerline L, and the second side member 20 is located on the longitudinal centerline L. Opposite second side. Similarly, the second and third transverse members 14, 16 are interconnected by third and fourth side members 22, 24, the third side member being entirely to one side of the longitudinal centerline L and the fourth side member b...

Abstract

A highway crash attenuator frame includes transverse elements that are interconnected by side elements. Each side element is disposed entirely on a respective side of a central longitudinal axis of the frame, and one or more tension elements are secured to the side elements to extend between the side elements across the longitudinal axis. Each tension element includes a mechanical fuse operative to fail in tension when the first and second side elements supply an excessive tensile load to the tension element. When the mechanical fuse fails in tension in an impact, the side elements are simultaneously released to move outwardly, away from the longitudinal axis, and thereby to collapse in a way which is coordinated between the left and the right sides of the frame.

Description

technical field [0001] The present invention relates to a frame for a traffic crash attenuator, such as an attenuator frame secured to a truck. Background technique [0002] US Patent 5,642,792 to June and US Patent 6,092,959 to Leonhardt disclose a traffic bumper that can be used to protect a vehicle, such as a truck. In both documents, the disclosed crash absorber comprises a frame having cross members with side members connected to each other. The side pieces are hinged so they can be folded outward, allowing the frame to collapse on impact. Premature collapse of the frame is prevented by restraints attached to the side members. In the June patent, the restraints include cables extending diagonally between the middle portions of the side members and a cross member. These cables prevent the side members from moving outwards until the pins securing the cables to the cross members are turned and released. In the Leonhardt patent, the restraints are in the form of bolts s...
