Title:
IMPACT DISSIPATING BOLLARD
Document Type and Number:
WIPO Patent Application WO/2022/171193
Kind Code:
A1
Abstract:
An impact dissipating bollard system includes a vertical stanchion and a composite energy-absorbing deformable cartridge configured to be positioned within a retaining foundation that includes a rigid core portion including a stanchion-receiving aperture and a plurality of flanges. An energy-absorbing resilient elastic sheath surrounds the rigid core portion and the plurality of flanges. The bollard system is configured such that impact energy is transferred from the vertical stanchion to deform the composite energy-absorbing deformable cartridge. A portion of the vertical stanchion beneath the retaining foundation and the composite energy-absorbing deformable cartridge form less than 35 percent of a total height of the impact-dissipating bollard system extending fewer than 80 cm beneath the surface of the retaining foundation such that the bollard system is configured for environments with dense underground utilities.
