Description

"IMPROVEMENTS TO LEGS FOR CONTAINER PLATFORMS ~ - MANUFACTURED ON CORRUGATED CARDBOARD BASIS.

BACKGROUND OF THE INVENTION To date there is a plurality of means to provide the platforms of containers made of corrugated cardboard, legs that allow them to separate from the ground or from the lower pallets. All of them, however, due to their characteristics, present the following drawbacks: They do not offer a sufficient resistance beyond a few centimeters of the periphery of the leg itself, which causes serious inconveniences when, for example, in a stowage, the legs do not exactly coincide with one another. other. Likewise, the damage caused by these legs on the lower stowage is remarkable when the upper weight that is stowed forces the pressure of the leg on the said stowage. Another additional disadvantage is that when there is accidentally a need to drag the container directly onto the floor, the legs inevitably deteriorate to the great detriment of the industry they serve. On multiple occasions when using forklifts, there is a high risk that when the fork of the same, when it hits a leg, it will break. The idea that serves as the basis for the present invention, originates from noting that many companies throw away the waste of paper and by studying a little the type of waste it was observed that some parts of said waste could be used, but we had no idea of how incorporate it into a container platform and it's When the main idea consisting of a single sheet of corrugated cardboard originates, it integrates three sections in the form of a channel, likewise it was observed in several companies that use even wooden pallets, they usually use a base of corrugated cardboard that they place on top of the wooden pallet, this with the purpose of not mistreating the products that are stowed, in such a way that in this invention this was considered and an extension was added to the sheet of corrugated cardboard in each of the sides and another sheet was added of corrugated cardboard with two other extensions, in such a way that when joining them with staples a tray is formed in the upper part of the platform for containers. The aforementioned disadvantages disappear when incorporated in the reference art, the invention that by means of the present application is intended to patent, as an obvious result, upon studying the description and observing the figures that illustrate it, the invention provides the following advantages: First: Easily platforms can be designed for containers according to the weight of the load, from 100 kilos to 3000 kilos, which for a wooden platform can not be done easily and if you tried the cost would be very high. Second: In view of the fact that the present invention allows cardboard waste to be used as raw material, the cost of the raw material is considerably reduced. Third: The assembly process is very simple and does not require machinery to be manufactured.

Fourth: The degree of support extends practically in the entire area of the platform, thus avoiding collapses in intermediate areas of said platform. Fifth: As a consequence of the combination of means used, a high degree of possibility of deterioration disappears in the event that the platform is dragged directly on the floor. Sixth: It is impossible, from a practical point of view, that in the normal operation of a forklift any of the legs that make up the sustenance of the platform can be damaged. Seventh: In several companies that use even wooden pallets, they usually use a base of corrugated cardboard that they place on top of the wooden pallet, this with the purpose of not mistreating the products that are stowed, in such a way that in our invention I consider this and an extension was added to the sheet of corrugated cardboard on each side and another sheet of corrugated cardboard was added with two more extensions. in such a way that when joining them with staples a tray is formed in the upper part of the platform for containers. On the other hand, as can be seen as the description is reviewed and the figures are observed, the method used to manufacture the legs is totally different from what is known, not so much by the general manufacturing principle, but by the extraordinarily simple methodology that It makes it possible to manufacture such platforms with greater ease, remarkable economy and overwhelming superiority when it comes to resistance.

These and many other improvements will be obvious as a result of what is explained and illustrated, so it is not the intention of the inventor to limit the scope of his invention to the foregoing, but to reserve for himself any variation following the principles described produce the same industrial results.

DESCRIPTION OF THE INVENTION The characteristic details of the present invention are clearly shown in the following description and the accompanying drawings, as an illustration of that serving the same reference signs to indicate the same parts in the figures shown.

Figure 1 shows a cross-sectional view of the folds that are made to the cardboard sheet to manufacture the platform. Figure 2 shows a side elevated view of one of the sides in which the notches in which the beams are accommodated can be observed. Figure 3 shows a view of the way in which a cardboard strip is folded to make an elongated cubic filler module. Figure 4 shows a view of the way in which the cardboard pieces are joined to make a longitudinal filling module. Figure 5 shows a view of a cylindrical filling module. Figure 6 shows an exploded view of a platform whose niches are filled with elongated cubic modules. Figure 7 shows an exploded view of a platform whose niches are filled with longitudinal modules. Figure 8 shows an exploded view of a platform whose niches are filled with cylindrical modules.

Figure 9 shows an exploded view of a platform in which reinforcement beams have been placed.

With reference to said figures, the present invention comprises in combination a platform (1) generally made of cardboard or any other similar material. which is made of a piece of cardboard (the) to which is subjected to a plurality of transverse folds (2) as a result of which are preferably formed three niches (3) and two tunnels (4) that finally provide the platform (1) three loader legs (5) that will support the weight of the load and the tunnels (4) through which the tips of the fork of the tractor that lift the load will penetrate. In each of the niches (3), the cubic filling modules (6), longitudinal (7) and cylindrical (8) that are manufactured by any of the following methods are housed: First: elongated cubic filling modules (6) ) by folding a cardboard strip (10) longitudinally to produce two sections (10A) in which they make a hangovers (10B), which is done by folding the cardboard strip (10) so that its ends (8) go forming right angles in each of the folds until the tips (8A) of the ends (8) converge on the inner face (9) of the strip (10). When such operation has been completed, a padlock (14) is inserted in the resaques (10B), which is also made of a strip of cardboard (10) that is folded transversely in half, producing two sections (14 TO); in each of these sections (14A) a hangover (14B) is made so that when both sections (14A) are joined, the hangers (14) coincide with each other, so that it is possible to insert the padlock (14) in the resaques ( 10B) of the sections (10B), when performing such an operation, the elongated module (6) is firmly secured without the need to use metal staples, metal clips or glue. Second: Longitudinal filling modules (6) joining by means of an adhesive a plurality of. cardboard strips (10) in order to form modules with a length equal to the length of the niche (3) in which they will be housed. Third: Forming cylindrical filling modules (6) formed with waste kraft paper and glue. However, unlike what is known at present, these modules are not exposed as is the case in the totality of the known art, but the same as previously mentioned, they are cloistered in the niches (3). On the platform (1) once formed by the folds that were made to the cardboard sheet (1A), the resulting side walls (12) project to a higher height than the legs (5), this it allows the tray (11) to be fitted between the projections (13), which will be supported on the filling modules (6)) so that the corresponding load can be placed on said tray (11).

The platform (1) will also be reinforced in some cases, by beams (12), also made of cardboard strips (10) that on one on top of the other (see figure 4), they acquire sufficient resistance to, with the filling modules (6, 7, 8), support the load with absolute security. For this purpose, the side walls (12) of the platform (1) have notches (14), in which the beams (12) are fitted, ensuring their permanent position.
