A telescopic edge protection post arrangeable between a floor and a ceiling, wherein the telescopic edge protection post comprises an outer tube having a floor end and a top end, and an inner tube having a bottom end and a ceiling end. The inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position. The post further has a locking mechanism arranged to lock the inner tube with respect to the outer tube, and a tensioning device. The locking mechanism comprises a fixed element, which is attached to the outer tube at its top end, and a movable element, which is movable with respect to the fixed element between a locking position in which the movable element engages with the inner tube and the fixed element to prevent the inner tube from being retracted into the outer tube.
A telescopic edge protection post arrangeable between a floor and a ceiling, the telescopic edge protection post comprising an outer tube having a floor end and a top end, and having a polygonal cross-section, an inner tube having a bottom end and a ceiling end, and having a polygonal cross-section, wherein the inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position, a locking mechanism arranged to lock the inner tube with respect to the outer tube, and a tensioning device, wherein the locking mechanism comprises a fixed element, which is attached to the outer tube at its top end, and a movable element, which is movable with respect to the fixed element between a locking position in which the movable element engages with the inner tube and the fixed element to prevent the inner tube from being retracted into the outer tube, and a non-locking position in which the inner tube is retractable into the outer tube, wherein the movable element is arranged at a corner of the inner tube and is engaged with, at least in the locking position, first two adjacent sides of the inner tube at said corner, thereby fixing, in the locking position, the inner tube relative to the outer tube in all transverse directions of the telescopic edge protection post.
A telescopic edge protection post arrangeable between a floor and a ceiling, the telescopic edge protection post comprising an outer tube having a floor end and a top end, and having a polygonal cross-section, an inner tube having a bottom end and a ceiling end, and having a polygonal cross-section, wherein the inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position, a locking mechanism arranged to lock the inner tube with respect to the outer tube, and a tensioning device arranged at an end of the telescopic edge protection post constituting one of the floor end of the outer tube and the ceiling end of the inner tube, and a gripper at each end of the telescopic edge protection post, wherein the tensioning device comprises a threaded rod having a first end attached to the gripper and extending into the telescopic edge protection post, the threaded rod being rotatably and longitudinally movably mounted at the tube at which it is arranged, a nut threadedly engaged with the threaded rod and slidingly arranged within said tube, and a spring extending within said tube between the nut and a spring seat, which is fixed, at least in a spring extension direction, relative to said tube, wherein the threaded rod extends through the spring and the spring seat, the spring thereby being tensioned by rotating the telescopic edge protection post.
