Description

OBJECT OF THE INVENTION

The present invention relates to a cardboard pallet, specifically an equivalent pallet

Half in plan of a conventional pallet, equipped with four inputs for handling by lifting systems, which is obtained from the development of a rectangular sheet with cut and fold lines so that in the assembly you get a pallet with the appropriate windows for the introduction of the fork of a forklift with access to the four sides of the palel, as well as the support surfaces

15 upper and lower palel.

The object of the invention is to achieve a cardboard pallet from a single piece, with the consequent saving of raw material. It is also the object of the invention to achieve greater ease in the assembly / assembly of the palel itself.

BACKGROUND OF THE INVENTION

The pallets that are currently manufactured in cardboard require for their realization more than one piece, which must then be conveniently linked together to form the pallet.

25 which undoubtedly represents a significant economic cost since the stamping of two independent pieces, their subsequent joining and a difficult assembly is required.

At the same time, there are no known cardboard pallets that have access to the forklift on all four sides of the palel.

DESCRIPTION OF THE INVENTION

The pallet that is recommended comes to solve the problem described above, since it presents as a fundamental characteristic the one to be obtained from the development of a

only cardboard sheet, which is rectangular and in which three correlative sectors are defined, one central and two lateral, the first one to form the support surface on the ground, while the two extreme sectors after folding will form the surface upper palel.

The central sector is delimited with respect to the lateral sectors through rectangular portions with cut and fold lines to allow the assembly and corresponding stiffening of the palel, counting for it with two windows and aligned with them five rectangular extensions that have to form vertical partitions laterals that relate the lower base to the upper base, that is to say with the sectors referred to in the first place, apart from constituting vertical assembly partitions for rectangular extensions derived from the extreme sectors, which fold conveniently and engage with the extensions that form the vertical lateral partitions, with the special feature that in the central sector that will constitute one of the bases, there are two rectangular die-cut areas with a fold line to form central partitions in which they engage grooves corresponding to the extreme extensions of the sectors lateral, thus forming I knew upper surface by means of these two lateral sectors and their anchoring, and of course part of the stiffening or internal vertical structure of the palel.

On the other hand, the lateral sectors have rectangular extensions at their ends divided into three sections, one intermediate and two ends, with bending lines to form the crimp and internal stiffening of the lateral sectors that must form the upper surface of the palel between them .

In correspondence with the ends of the intermediate or central sector constituting one of the base surfaces of the pallet, "T" extensions with transverse folding lines are provided to form a vertical partition on each side, with an extension corresponding to the transverse branch of the commented "T", which is on the inside and attached to the inner side of the other base, thus establishing two windows on each end side for the passage of the fork branches corresponding to the forklift, that is to say manipulator of the pallet, complementing those windows with the folded inwards and vertical arrangement of the extreme extensions of the lateral sectors, and thereby achieving optimum stiffening of the pallet as a whole.

Obviously, being able to get a cardboard pallet in one piece means a very significant saving of material compared to what is conventionally required where two or more pieces of cardboard are used for the same purpose, as well as being easier to assemble.

In this way, a pallet of half-plan dimensions than conventional ones is achieved, in which four inputs are defined for handling by conventional lifting systems.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the pallet of the invention, which is equivalent to a conventional pallet half, in which four entrances are defined for handling by conventional lifting systems, is obtained from the development of a rectangular sheet of cardboard, as shown in figure 1, in which three parts or sectors are established, one central and referenced with the number (1) and two sides referenced with the number (2), the central being larger than the lateral sectors, the first constituting one of the bases, specifically the support surface of the pallet once formed on the ground, while the sectors (2), in the assembly of the pallet will together form the upper surface of the pallet, that is the surface of support for the load.

Between the sector (1) And the two lateral sectors (2), two bands are established with punched extensions with fold lines, and that correspond to a pair of windows (3), which on each side are aligned with extreme extensions (4) , rectangular, and a central extension (5), as well as two lateral ones (6) to the latter, whose function will be exposed later.

In correspondence with the sides of the sector (1) that will constitute the base of the pale !, windows (7) have been established that establish anchoring elements in the assembly of the pale !, as will be discussed later.

Each of the lateral sectors (2) has a central rectangular extension (8) affected by a pair of recesses (9), also having a pair of extreme extensions (10).

On the other hand, the ends of the lateral sectors (2) also have a central and lateral extension (11) from which, after corresponding bending lines, two extensions (12) are derived.

As for the central sector (1), it presents in an intermediate zone a pair of rectangular contours (13) punched in correspondence with three of its sides, and a fold line (14) in correspondence with the last side, while the ends of that central sector (1) they have extensions in "T", whose vertical branch (15) is perfectly centered and the transverse branch has a groove (16) that gives rise to the two branches (15 ') of the transverse branch of the "T" extension referred to above.

The extensions (12) have lateral prominences (17), while the central sector (1) has small windows (18) in proximity to its ends.

In view of the development of the sheet of Figure 1, discussed above, the pallet assembly begins by folding each of the lateral sectors (2) until they are placed parallel to the intermediate sector (1), previously folded into the interior of the sectors (6), which must be superimposed on the sector (5), forming a double wall between this sector (5) and the two sectors (6) superimposed on it, so that the projections (17) of the sectors (6) , when the sectors (2) are folded horizontally, they are housed in the windows (7) of both the central sector (1) and the extreme sectors (2) themselves. Thus, when the sectors (2) have already been folded horizontally, the base of the pallet determined by the sector (1) and the opposite or superior base of the same pallet determined by the coplanar arrangement of the sectors (2) are formed , so that the extreme laterals originated by the folds of the sectors (2) on the sector (1) form the windows (3) to which those formed by the folding towards the interior of the extensions (6) are joined, and whose rectangular windows on each side will be those that determine the means of introducing the fork branches in a forklift.

Next, the rectangular and die-cut areas (13) of the central sector (1) are folded perpendicularly, through the fold line (14), said parts or zones being cut (13) vertically, parallel to each other and fit for interlocking on them the rectangular extensions (6) of the sectors (2), by inter-coupling between the grooves (13 ') of the die-cut parts (13) and the grooves (9) of the extensions (8), remaining this in vertical arrangement in correspondence with the center and logically attached to that of the other side to be thus perfectly assembled and stiffened the sectors (2) that have to form the upper seating surface for the loading of the palel.

Likewise, the extensions (4) have been folded inwards to also be arranged perpendicularly and attached to those of the opposite end sector (2), thereby enhancing the central stiffening of the palel.

Once the two upper and lower surfaces of the pallet have been achieved, in accordance with the folds and crimpers mentioned above, the extensions in 'T' of the ends of the central sector (1) are made, forming the rectangular and central extension ( 15) a vertical partition on the respective side, while the extensions (15 ') fold inwards and are superimposed on the inner face of the base that form the two sectors (2), engaging in the grooves (16) of the sectors or extensions (15 ') the extensions (10) corresponding to the ends of the lateral sectors (2).

Next, the extensions (12) are folded over the extension (11)

corresponding to the sides or ends of the sectors (2) that together form the upper surface of the pallet, folding inwards to be the central extension (11) superimposed on the end part of the corresponding sector (2) and the extensions (12) lateral walls forming vertical partitions supported by the sector (1) that forms the base surface 5 of the pallet, so that the projections (17) of these extensions (12) fit into the windows (18) of the commented central sector (1), leaving Thus the pallet is perfectly assembled, with an upper surface determined by the sector or sectors (2), a lower surface formed by the sector (1), and some sides with the windows that originate the windows (3) and extensions due to the folds of the extensions (6), and in the others

lOdos side windows that are formed on either side of the extensions (15), so that four windows are determined on each side for the introduction of the corresponding branches of the fork of the forklift that manipulates the pallets.

Obviously due to the arrangement of the various folded and crimped extensions

15 as previously stated, the pallet is perfectly armed without the need for any additional element, in a phase or process of correlative phases of utmost operational simplicity to achieve the pale!
