DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a loading platform with dismountable legs, for the transportation and warehousing of goods, and having the special feature of its supporting legs being dismountable in order to facilitate replacement when damaged and, at the same time, reduce the space occupied by the empty platform when it is not in use. The design also permits the empty platforms to be stacked without removing the legs, the legs of each platform slotting into those of the one immediately next to it. In this case the platforms present an incut on the edge in order to facilitate grasping with the fingers.
BACKGROUND OF THE INVENTION
Known in the art are various types of platforms which comprise several layers of cardboard superimposed and glued, provided with circular openings surrounded by a lowered section or depression resembling a circular crown situated on the top side of the platform. Into these openings are incorporated in removable manner the same number dismountable legs of inverted truncoconical shape, which have at their upper bases pairs of projecting, radial, parallel fins in the form of a circular crown, of which fins the ones occupying a higher position have an interruption or opening delimited by two bevelled edges which form a substantially helicoidal edge. The lowered section or depression which surrounds each opening of the platform is provided with a cut through which the upper radial fin is inserted by means of a rotating movement similar to that of screwing, so that, once the leg has been inserted into the opening, the depression or lowered section is trapped between the two fins and the leg is immobilized.
Subsequent studies carried out on this type of platforms have permitted the conclusion to be reached that the presence of the two radial fins with which the legs of the platform are provided increases the cost of the platforms and hinders the operations of fitting the legs onto the platform and removing them from it.
Moreover, the known embodiments present limitations in respect of the shape of the fins, which have to be circular and are not very suitable for legs of non-circular outline, for example, rectangular legs. Furthermore, if the platforms are stacked without removing the legs it is difficult to separate the platforms from each other.
DESCRIPTION OF THE INVENTION
The loading platform with dismountable legs of the invention, in which the legs have a single fin, which can be circular or rectangular, has been designed in order to provide a solution to the disadvantages outlined.
The loading platform with dismountable legs is composed of one or more layers glued to each other, preferably made of cardboard, each layer provided with regularly distributed openings which match those of the other layers, into which openings are inserted as many dismountable legs provided with a radial fin with an incut. The fin has opposite edges with slopes by way of ramps to facilitate the introduction and removal thereof in a space which surrounds the outline of, at least, the greater part of each opening, through a notch or widened section of same, which forms an inlet through which the aforesaid fin penetrates. On the basis of this embodiment, the platform is essentially characterized in that the space which follows the outline of the opening is situated between two layers of the plate, while each leg has a single external radial fin which, once mounted on the plate, is trapped between the two layers.
More specifically, the plate comprises three layers, of which the upper and lower layers have identical matching openings. The openings of the lower layer have, at least, one notch or widened section for introduction of the fin of the corresponding leg. The intermediate plate has similar openings which match those of the upper and lower layers, but are of larger dimensions, thereby forming the space in which the fin of the corresponding leg is housed.
In one possible embodiment, the legs of the platform are of truncoconical shape, with a fin of circular outline. The openings are likewise of
