Patent ID: 8246267

Claim:
A safety post comprising an elongate tubular member and a locking device arranged inside of the tubular member at a first end thereof, which is arranged to be received in a post holder, wherein said locking device includes a lever and a bias spring device biasing the lever against a first inner surface of the wall of the tubular member, wherein the lever has a lock protrusion extending through a first aperture portion of said wall, and protruding from an outer surface of said wall, and a release protrusion extending through a second aperture portion of said wall, and protruding from said outer surface, wherein said release protrusion is arranged at a distance from said lock protrusion, and farther from said first end than the lock protrusion, wherein the lock protrusion is retractable to a release position inside of said outer surface of the tubular member by operation of the release protrusion in a counter biasing direction, in a first operation step requiring a first operation force exerted on said release protrusion, wherein said release protrusion has a support surface, which is arranged to support the safety post against said post holder, and wherein said release protrusion is related to said lock protrusion such that in the release position the release protrusion is still protruding from said outer surface, and wherein a non-protruding position of the release protrusion is obtained by a further operation of the release protrusion in the counter biasing direction, in a second operation step requiring a second operation force, which is distinctly higher than the first operation force, wherein said lever has an elongate major portion, extending substantially longitudinal of the tubular member, and comprising a first end of the lever, and a second end of the lever is an elongate end portion, connected with said major portion at an angle greater than 0° and less than 180° wherein in the first operation step the release protrusion is depressed such that the first end engages and pivots about the first inner surface of the wall such that the second end approaches and engages an opposite inner surface of the wall, and in the second operation step the second end engages and pivots about the opposite inner surface of the wall such that the first end approaches the opposite inner surface of the wall.
