DEVICE FOR A STANCHION ON A LOADCARRYING PLATFORM OF A VEHICLE

Abstract: A device at posts (11) for cargo platforms (22) of vehicles, and of the kind that comprises a lock mechanism (12) built into the post for detachable locking of the post to the cargo platform. A lock mechanism, comprising an operating handle (13) for cooperation with a platform socket. The operating handle (13) is designed as a lever with two arms (17, 28). The operating handle (13) is journalled in bearings with free rotation around the rotation point (14) of the lever to one end of a link (15), the opposite end of which is journalled in bearings to the post. The rotating motion of the link (15) is constrained by a stop member (25), allowing the link to swing out sufficiently for the post to clear the platform socket (20). One lever (17) of the operating handle (13) is equipped with a lock member (18) for cooperation with a corresponding first lock member (19) at the upper part of the platform socket (20). A lock bolt (24) is arranged at the lower end of the post for cooperation with a corresponding second lock member (23) at the lower end of the platform socket (20).

Description: Title Device for a stanchion on a loadcarrying platform of a vehicle. The present invention relates to a device at posts of the platform of a vehicle, and of the kind that comprise a lock devise built into the post, for a detachable locking of the post to the platform, and which comprises an operating lever for cooperation with a socket in the platform. BACKGOUND OF THE INVENTION, AND THE PROBLEM As a rule, the lock device of conventional posts has a dual function, in part to fix the post to the platform, and in part, independently of this lock function, to be able to fix one or more hatches to the post. These mechanisms are relatively complicated. Many lorries are loaded mainly from the rear end, and have detachable posts along the sides, without any particular lock mechanism to which boards are attached in order to laterally restrain the cargo, and for protection against cargo displacement. These posts are heavy and not easy to handle, in particular if they constitute part of the frame for the platform cover, and extend all the way to the handrails of the frame. THE PURPOSE OF THE INVENTION AND THE SOLUTION OF THE PROBLEM The purpose of the invention is to achieve a post with a lock mechanism: 1. which has a simple construction, 2. which can be locked efficiently and reversibly to the edge of the platform, even though the socket for the post is recessed into the edge of the platform, 3. which by way of controlled movement can be lifted and lowered to the platform socket, and 4. which by a simple hand grip can be constricted, with transfer of torque, to the platform socket. These tasks have been solved by designing the operating handle in the form of a lever with two arms, so that the operating handle is rotably journalled in bearings around the turning point of the lever at one end of a link, the opposite end of which is journalled in bearings at the post, that the rotating motion of the link is limited by a stop member, which allows the link to swing out sufficiently for the pole to clear the platform socket, that one lever of the operating handle is equipped with a locking member for cooperation with a corresponding locking member at the upper part of the platform socket, and that a lock bolt is arranged at the lower part of the post, for cooperation with a corresponding second locking member at the lower part of the socket. DESCRIPTION OF THE DRAWINGS The invention will be described more closely, in the form of an exemplary embodiment, with reference to the enclosed drawings. Fig. 1 shows the post of the invention in a frontal view. Fig. 2 shows a section along the line II - II in Fig. 1. Figs. 3, 4, and 5 show sections, analogous to Fig. 2, through the post, with the lock mechanism in various open and closed positions, respectively. Fig. 6 shows an alternative embodiment of part of the lock mechanism. DESCRIPTION OF THE EXEMPLARY EMBODIMENTS The post, in its entirety referred to as 11, is comprised of a pipe of rectangular section, in the lower part of which is arranged a lock mechanism 2. This comprises an operating handle 13 in the form of a lever with two arms, the rotation point of which is comprised of an axle neck 14, journalled in bearings at one end of a link 15, which is rotably journalled to the inside of the post through an axle 16. To the shorter arm 17 of the operating handle 13 is attached a rotation and lock member 18, in the shape of a cylindrical axle, arranged to cooperate with a complementary shaped forklike lock member 19, at the upper part of a platform socket 20. This is welded to the edge 21 of a cargo platform 22. Another fork shaped lock member 23 is arranged on the bottom side of the platform socket 20, for cooperation with a lock bolt 24, fixed to the lower end of the post 11. The swinging motion of the link 15 around the axle 16 is limited by a stop member 25, constituted of an arm, one end of which I journalled in bearings to the link 15, while the other end I capable of performing an axial motion in the longitudinal direction of the pole. An end stop member 26 allows the arm to swing out to an extent that the pole clears the platform socket 20, which takes place in cooperation with a catch 27, attached to the inside of the post. The second, longer, lever arm 28 of the operating handle 13, designed as a handle, is equipped, at its free side, with a snap lock 29 or similar, which in the unfolded position, inserted into the post, engages a lock feather 30 during simultaneous compression of a pressure spring 31, positioned between the posterior wall 32 of the post 11, and the link 15. At the lateral edges of the post 11, pockets 33 are arranged for lateral cargo guards 34, which are suitably comprised of removable boards. When mounting the post 11 in the platform socket 20, the post is lifted with the operating handle 13 folded, as shown in Fig. 5, so that the lock member 18 can engage the fork-shaped first lock member 19. By rotating the operating handle 13 upwards around the axle neck 14 with the lock member 18 resting against the lock member 19, the post is lifted through a controlled movement, to its position in the platform socket 20. Towards the end of the movement of the operating handle 13, the arm, which have been resting on the catch 27 throughout the previous rotating motion and limited the swing-out of the link 15, will leave the catch 27 and be displaced upwards, sp that the lock bolt can engage the second fork-shaped lock member 23. With the operating handle 13 in the folded position of the post, the snap lock 29 comes into action, and holds the operating handle in place. In a similar manner, but in reversed order, the snap lock can be opened through applying pressure to the same, and the operating handle 13 can be swung outwards, whereby the post 11 initially is lowered in the vertical direction, sp that the lock bolt 24 can disengage from the lock fork 23, whereafter the post can be swung away from the platform socket 20, which may be retracted into the platform 22, in such a way that the post with the pockets 33 for the lateral cargo guards can be guided past the edge of the platform. The stop member 25 ma}' be embodied in various ways. For example, the arm 25, described above, may have the reverse function, i.e. it may be journalled in fixed bearings to the post, and in its lower end axially displaceable along a groove in the link 15. Another alternative is shown in Fig. 6, in which the stop member 25 is constituted by an extension 35 of the link 15, counted from the rotary axle 16 of the link. The extension is dimensioned in such a way that its end abuts the inside of the post when the post has been swung out far enough to clear the platform socket 20.
