PEG-9 novel due to the fact that it is formed of a moldable material ina single piece body.

SUMMARY OF THE INVENTION The pallet of the invention generally comprises a substantially rectangular frame, each side of which is composed of two aligned portions formed by partitions of equal length. The sides of the rectangular frame are joined by means of other internal partitions which are grouped aboutand extend outwardly from acentral portion which.is approximately X-shaped. From the ends of the arms of the X-shaped portion extend eight internal partitions, grouped in pairs to form a cross-in such a mannerthat each of the double legs of the cross are joined to the ends of the arms of the X-shaped portion andto a centralzone of one ofthe sides of the exterior rectangular frame.

The structure is completed by means of two plates which form the upper and lower surfaces of the pallet. Such plates have therein a series of weight-reducing holes and non-skid ribs, "while the comers of these plates are provided with hollow columns whichare precisely positioned at the vertices of the rectangular frame. z l

The central area of thefectang'ular frame is hollow, and each portion of each side thereof has an orifice which aligns with a similar orifice in an internal'partition forming a leg of the internal cross. The aligned orifices thus form tunnels for "the receipt'of thearms of'the fork of a conventionaLfork lift truck.

BRIEF DESCRIPTION OF THE DRAWINGS The structure of the invention is illustrated in more detail in the attached drawings, wherein:

FIG. 1 is a lower plan view of a pallet according to the invention.

FIG. 2 is an upper plan view of such pallet.

FIG. 3 is a section taken along III-III of FIG. 2.

FIG. 4 is an elevational view of the pallet along one of the longer surfaces thereof.

FIG. 5 is an elevational view similar to that of FIG. 4, but taken along one of the shorter surfaces of the pallet.

FIG. 6 is a section taken along line VI-VI in FIG. 4.

FIG. 7 is a section taken along line VII-VII in FIG. 1.

FIG. 8 is a section taken along line VIlI--VIII in FIG.

FIG. 9 is a perspective view illustrating the structure of the pallet, but with the upper plate surface thereof removed to facilitate illustration of the internal structural arrangement.

DETAILED DESCRIPTION OF THE INVENTION As can be seen with particular reference to FIG. 9, a pallet according to the present invention is formed of an X-shaped central core or nucleus 1 having extending from the end of each leg thereof, and in directions perpendicular to each other, a pair of internal partitions 2. Thus, there is formed a cross, each arm thereof being formed by a pair of partitions 2, and the center of which is core 1. Each partition 2 has therethrough a preferably rectangular opening 4 aligning and coinciding with other similar openings 5 in external partitions 3 which form the external side surface of the rectangular frame of the pallet. The coincidence of the preferably rectangular openings or windows 5 in the external frame, and the preferably rectangular openings or windows 4 in the legs of the cross, thus provide tunnels, two at each side or side surface of the pallet, for the receipt of the arms of the fork of a conventional fork lift truck. 3

External partitions 3 join. internal partitions2 at positions slightly recessed inwardly with respect to the length thereof, so that the zones corresponding to the imaginary vertices or corners of the hexagonal prismshaped pallet are provided with hollow columns 6 which reinforce the assembly. Brackets or braces 7 are also provided for the purposeof reinforcing the pallet. Such brackets are triangular in shape and are arranged, at regular intervals and parallel to each other, in each of the gapsin the side surfaces of the pallet formed by the partitions 3 being inwardly recessed with respect to the outer ends of partitions 2 and columns 6.

The upper and lower plates which constitute the actual pallet loading surfaces have therein a series of orifices 8, which are preferably square-shaped, and whose sides have downwardly facing wings or flanges 9 which act as a reinforcement of the internal partitions 2.

The hollow areas 11; which are formed between pairs of partitions 2 along the axes of symmetry of the pallet, have formed in the respective upper and lower plates, depressions 12 which cover the complete length of areas-11, thus forming canals which, withthe help of orifices 13 in both the upper and lower plates of the pallet, act as drains. v

The hollow columns 6 may also be provided with drain holes. 1

The external portion of the loading surfaces, i.e. upper and lower plates which cover the internal structure of the pallet, may be provided with ribs or flanges 14 such as those represented in FIG. 3. Such ribs 14 act as anti-skid elements for the pallet when they are formed into rows.

The device of the present invention will be formed in a single element or integral piece and will thus overcome the difficulties caused by the use of conventional pallets made, for example, of separate plates or sheets, screwed or nailed to each other, which with use generally tend to come loose or separate.

On the other hand, due to the nature of the material, which will preferably be plastic, from which the pallet is made, the pallet is resistant to the atmosphere. Further, the pallet of the invention is light in weight but has a high degree of strength and rigidity.

The orifices distributed on the upper and lower surfaces of the pallet reduce the weight thereof, while the wings or flanges 9 which project inwardly from the faces of the pallet, reinforce the assembly.

It is not considered necessary to further extend this description, since any person skilled in the art will readily understand the concept of the invention as well as the advantages derived from its industrial exploitation.

Therefore, it will be understood that modifications may be made to the specific structural arrangement discussed above without departing from the scope of the present invention.
