DESCRIPTION

Pallet with upper enervation surface Object of the invention

The present invention relates to a pallet made of plastic material, which comprises an irregular upper surface for loading the goods, that is, it has irregularities that make the goods immobilized, which, in turn, facilitates the holding of the merchandise. on the pallet object of the invention.

Technical problem that is solved and background of the invention

Placing items such as beverage bottles in plastic boxes is a common practice, both for storage and for the distribution of such items. If said boxes are placed on pallets of the currently known type, they move and slide on them, since the said pallets are formed by stringers, usually made of wood, which comprise a flat and smooth upper surface and do not contain any means of retention of the load placed on the pallets.

A usual design of a pallet structure consists of a sufficiently rigid and resistant set of stringers, usually made of wood, that supports the weight of the load. In this rigid assembly a superior surface, generally flat, is distinguished on which the goods supported by the pallet are placed, and a lower support surface, which is sometimes replaced by legs or sets of legs that distribute the load supported by the I hit the ground. The legs can be connected to each other by means of longitudinal lower extensions that constitute joining sections between said legs. Openings are always generated between the legs so that the arms of a forklift or a pallet loading truck can be introduced into said openings.

In the state of the art, several documents are known where pallets for the storage and transport of products are disclosed. Among others, the document ES 1 079 113 U discloses an improved pallet structure consisting of a modular structure so that the elements that are damaged during the use of the pallet can be replaced without the need to discard the pallet in its entirety.

Another document, WO 2006 013 308 A1, discloses a pallet of plastic material, where the plastic material is mixed with nanotubes thus providing lightness, load capacity and greater impact resistance. Another document is also known, BE 1 010 793 A3, which discloses a modular pallet that allows the modification of the dimensions of the pallet according to the user's needs. Consequently, many of the known pallets offer a smooth upper surface where the load is placed, so that none offers its own fastening means that prevent the load from moving and sliding on the pallet. When a load needs to be fixed on a pallet, an external means is usually used to attach the load to the pallet. On the other hand, pallets are known comprising upper surfaces with ribs. It refers to the international patent WO 20 10/028334 A2 and the US patent US 2004/0007164 A1, both documents disclose pallets in accordance with the preamble of claim 1.

In order to avoid the aforementioned drawbacks and achieve the aforementioned goals, the invention discloses a pallet according to claim 1. The pallet is made of plastic material that offers an upper interlocking surface, so that said upper interlocking surface It helps hold the loads that are placed on the pallet.

The pallet with upper interlocking surface object of the invention comprises an upper surface, a lower surface and a lateral surface. In said pallet, the upper surface comprises a perimeter edge and a series of main ribs arranged orthogonally with respect to each other, which divide the upper surface into quadrangular housings forming a stepped configuration of the quadrangular housings.

In the pallet with upper interlocking surface object of the invention, an upper surface with an irregular profile is defined, where the load is fixed thanks to the perimeter edge, the main ribs and the quadrangular housings.

In the pallet with upper interlocking surface object of the invention, the quadrangular housings comprise internal ribs that divide each quadrangular housing into a series of interlocking openings.

In the pallet with upper interlocking surface object of the invention, the interlocking openings are openings with exit.

Description of a preferred embodiment

The pallet (1) object of the invention is a pallet specially designed to support on its upper surface (7) boxes (6) of the type used to store and distribute beverage bottles, so that the shape and components that shape the surface upper (7), provide said upper surface (7) with an irregular surface that prevents said boxes (6) from moving.

The pallet (1) object of the invention (as seen in Figure 1) comprises an upper surface (7), a lower or support surface (8) and a series of attachment points (10) between the two surfaces (7, 8). The joining points (10) form a series of lateral openings (17) on the lateral surfaces (9) where the arms of a forklift or the loading truck are introduced to move the pallet (1).

The upper and lower terms referring to surfaces are relative terms that refer to the position of the pallet (1) according to figure 1, where the pallet (1) is ready to receive the load.

Everything described, except for the fact that the pallet (1) object of the invention is made of plastic material, conforms to the description of any pallet (1) used today.

The novelty of the invention resides in the upper surface (7) of the pallet (1) object of the invention, since until now the upper surface (7) of the pallets (1) has generally been designed as a smooth surface on which the merchandise is placed, although, when the merchandise must be attached to a pallet (1) external means are used to hold the merchandise, either wrapping the merchandise with a plastic film or using tapes or strips that join merchandise and pallet (one).
