Abstract: A platform stanchion (13) easily lockable to the edge of the platform (10) of a truck has a canvas-cover supporting post (17) consisting of an upper pole (26) and a lower U-section (25) connected thereto. The stanchion (13) engages with the post (17) by means of a tapered upper portion (23) with a tongue at its top. For receiving the upper portion (23) of the stanchion, the U-section (25) of the post (17) has a mating tapered recess with an opening at the top for receiving the tongue. The stanchion (13) and the post (17) can be pivoted inwards and outwards relative to each other with the tongue located in the opening of the U-section serving as pivotal center. In the swung-in position with the stanchion (13) and the post (17) aligned with each other, the stanchion is accommodated in the U-section of the post.

Abstract: An arrangement for detachably mounting a platform stanchion on the edge surface of a truck platform comprises an attachment (10) which is permanently secured to said edge surface. The attachment has an upper and a lower horizontally projecting yoke (12 and 13, respectively). The rear wall (15) of the stanchion has at its lower end a tongue (20) insertable into the lower yoke (13), and an opening (25) adapted to be moved over the upper yoke (12), such that a locking key (23) can be pushed through the yoke on the stanchion side facing away from the edge surface. The wall surface of the stanchion facing said edge surface has a recess and, within the confines of said recess, a projection (22). The recess and the projection are dimensioned to receive the attachment (10) in the recess, such that the projection (22) extends through a hole in the attachment (10).
