DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a stanchion for goods vehicles.
PRIOR ART
Stanchions for goods vehicles have hitherto normally been made of bent steel plate welded together to form a box containing the mechanism which is required for operating the stanchion. Such a stanchion is heavy, expensive to produce (as a result of bending, welding and surface treatment) and is not easy to service.
Technology has hitherto been lacking for producing stanchions from materials such as aluminium which afford clear advantages with respect to weight and freedom from requirements of surface treatment.
THE INVENTION
A stanchion according to the invention is made up of at least two sections which are preferably made of aluminium and are provided with cooperating, longitudinal ridges and grooves for guiding when pushing the sections together axially to form a stanchion and for transmission of forces during use, wherein a mechanism known per se for operating the stanchion can be arranged in a space formed by the sections.
A strengthening section of the same character as the other sections can be inserted in the stanchion at its most stressed part.
The sections can be held together simply by screws, rivets or similar elements.
BRIEF DESCRIPTION OF THE DRAWING
The invention will be described in greater detail below with reference to the attached drawing, in which
FIG. 1 shows a previously known stanchion for a goods vehicle,
FIG. 2 is a perspective view of a stanchion according to the invention, and
FIGS. 3A-C are cuts through three sections incorporated in this stanchion.
DESCRIPTION OF A PREFERRED EMBODIMENT
FIG. 1 shows a previously known stanchion 1 for goods vehicles. With the aid of a mechanism, which is generally designated 2, the stanchion can, on the one hand, be releasably fixed on a platform edge 3 and, on the other hand, releasably fix flaps (not shown) in the raised position. Since the figure, which is taken from European Patent No. 0 090 835, is primarily intended to illustrate the mechanism 2 in the stanchion, the stanchion 1 itself is in fact only indicated.
Such a conventional stanchion is, after assembly of the mechanism, normally welded together by two steel sections--a level base section and a U-shaped section. The stanchion is heavy and thus difficult to handle, in addition to the fact that its weight limits in a prejudicial manner the possible net load of the vehicle. The welding makes the stanchion expensive. The steel plate material used means that rust protection and surface treatment are required. Finally, servicing the mechanism is difficult to carry out, as a result of the welding.
A stanchion according to the invention, which is shown in FIG. 2 and FIGS. 3A-C, is instead made up of sections preferably made of aluminium or the like, which sections can be simply inserted into each other in their longitudinal direction by virtue of the fact that they are equipped with cooperating ridges and grooves. Moreover, since all the essential parts of the mechanism can be made of aluminium, great advantages are achieved in the abovementioned respects.
FIG. 3A shows a base section 4 which can be said to consist of a base plate and two legs which project upwards therefrom and which are in each case provided, on their surfaces facing each other, with two longitudinal ridges 5. The result is a U section with protruding flanges against which the flaps of the goods vehicle are intended to bear in the raised position.
FIG. 3B shows a covering section 6 which can be said to consist of a plate, where appropriate channelled on the top side, and two legs which project downwards therefrom and which are in each case provided, on their surfaces facing away from each other, with two longitudinal grooves 7.
The base section 4 and covering section 6 can be fitted together to form a stanchion for a goods vehicle by being pushed together axially, in which connection the ridges 5 and grooves 7 cooperate in a guiding manner and, during subsequent use on a goods vehicle, also to transmit forces.
