1. Method for manufacturing loading platforms fitted with replaceable feet and comprising one or more mutually bonded layers, each layer having evenly distributed openings, the openings in each layer coinciding with those of the remaining layers in which respective feet are dismountably incorporated, said feet being hollow and open on their upper face, the width of said feet decreases toward a lower floor supporting base, each foot being provided with a peripheral lug fitted with an interruption having two opposite slanting edges in the form of ramps designed to facilitate their insertion into and removal from an internal space located between two layers forming the platform through a notch provided in the openings of a lower layer located on the lower face of the platform, thereby enabling insertion and removal of the lug of the corresponding foot;

  • the openings of an intermediate layer of the platform being larger than although similar to the openings of the lower and upper layers, thus allowing for the formation of the above mentioned internal space;

    the method comprising the steps of;

    placing a first layer with its corresponding openings already die cut on a work bench in the form of a supporting block which is fitted with cavities coinciding with the layer openings of the intended platform layers, said platform having a width and depth permitting the insertion of platform feet, the peripheral lug of said feet constituting a feet insertion stopping means by abutment against the first layer;

    bonding a second layer onto the first layer, said openings in said second layer coinciding with those of the first layer;

    the second layer opening contour being equivalent to that of the radial lugs in said feet, said radial lugs on said feet having substantially the same thickness as said second layer;

    bonding at least a third layer onto the second layer, said openings in said third layer coinciding with those of said first and second layers;

    the third layer openings being equivalent to those of the first layer; and

    pressing the assembly of said first, second and third layers and feet in order to consolidate adhesive between said first, second and third layers, the peripheral lugs in the feet thereby remaining at the height of said second layer, trapped between said first and third layers.
