Abstract

Column limiting the passage of vehicles, folding, of the type comprising a tubular body articulated by its base with respect to a plate anchored in the ground, whose column is provided with a device for locking the joint characterized by - said tubular body (10) is rectangular oblong cross section, with an upper wall, a lower wall and two side walls, seen when the tubular body is folded; - the axis (12) of said articulation is located perpendicular to the two mentioned side walls, in a position very close to said lower wall; - said blocking device is internal to the column and comprises a movable locking element (18) mounted so that it gravitates towards a closing position when the column adopts a vertical position, whose hook-shaped element (18) is attached to the internal surface of said upper wall, it is rotatable with respect to an axis (19) perpendicular to said upper wall and is connected to a connecting rod and crank mechanism (22, 23) governed by a lock (24) accessible from the outside, capable of rotating said locking element 18 in the opening direction and whose connection also allows said element (18) to rotate slightly without actuating said mechanism (22, 23) and by integrating a cylindrical projection (21) integral with said plate ( 11) provided with a bevelled end surface (21a), located in a fixed position such that it is capable of cooperating with an adapted lateral surface (18a) of a lower end of said enclosure element. (18) to angularly displace it in the opening direction, in the transition of the tubular body (10) to a vertical operative position, the projection (21) being trapped by said element (18) upon passing the latter, by gravity to a closing position.
