Abstract
An arrangement for attaching a falling post on a base structure, the post being rotatably movable between a standing and a recumbent position. The arrangement includes a stand, wherein the post is attached pivotally to the stand by a pin. The stand includes at least one groove arranged laterally in respect to the post, and the post has at least one projection extending in a lateral direction from the post. The at least one groove is arranged with respect to the at least one projection such that when the stand is in the standing position, the at least one projection lies in the at least one groove, and thereby locks the post in the standing position. The at least one projection is attached to the post such that it may move with respect to the stand in a longitudinal direction of the post.

An arrangement attaching a falling post on a base structure, the post being rotatably movable between a standing and a recumbent position, the arrangement comprising:
- a stand including an attachment element arranged for attaching the falling post to the base structure, wherein the post is attached pivotally to the stand by a pin, the post being arranged to rotate from the standing position to the recumbent position with respect to the stand, the stand having at least one groove arranged laterally with respect of the post, at least one projection extending in a lateral direction from a sleeve that is movably disposed on the post, the at least one groove being arranged with respect to the least one projection such that when the post is in the standing position, the at least one projection lies in the at least one groove, and thereby locks the post in said standing position, the at least one projection being attached to the post and arranged to move with respect to the stand in a longitudinal direction of the post, an exterior of the stand including a guidance surface ending at the at least one groove, the guidance surface being arranged to lift the at least one projection along the post and guide said projection to move into the at least one groove;
- and
- a lever rotatably attached on the stand, the lever including a first end and a length of the lever being arranged to extend past the guidance surface when the post is in the recumbent position such that the at least one projection is arranged to move on the guidance surface to push the first end of the lever and rotate the lever in a first direction therewith, and the at least one projection being arranged to push down the first end simultaneously with moving into the at least one groove, such that when the post is in the standing position the first end of the lever is situated under the at least one projection lying in the at least one groove, and wherein the lever is arranged when activated to rotate in a second direction opposite to the first direction, the first end of the lever being arranged to lift the at least one projection away from the at least one groove, thus allowing the post to be moved towards the recumbent position.
