Abstract
A safety bollard, post or stanchion to protect adjacent a vehicular area, each bollard, post or stanchion being so designed to provide a progressively increasing resistance to bending and/or deformation on impact by a vehicle, whereby the force of impact is progressively absorbed by the bollard, post or stanchion and deformation of the vehicle whereby the vehicle is progressively decelerated.
Claims20
A safety bollard for resisting entry of a vehicle into an area, the bollard embedded in granular material in a base, the base being embedded in the ground, and an annular buffer collar surrounding the bollard at the upper portion of the base above the granular material, with the buffer collar fit between the bollard and the base, wherein on impact the bollard it tiltable with respect to the base, with the buffer collar being deformable and the granular material being displaceable to provide a progressive increase in resistance to the tilting of the bollard.
A safety bollard comprising:
- a. an elongated stanchion having a bottom section and a top section;
- b. a rigid base having a top surface with an interior pocket descending therefrom, wit the stanchion having its bottom section situated within the pocket so that the top section of the stanchion protrudes upwardly from the pocket in the base;
- c. a collar fit about the stanchion within the pocket, with the collar being situated between the stanchion and the base to space the stanchion from the base, with the collar having an outer diameter approximating the inner diameter of the pocket, the collar being deformable when the stanchion is subjected to vehicle impact.
