Definitions
- a handling pallet generally comprises a top plate of substantially rectangular shape and projecting feet or studs protruding under the plate.
- Handling pallets are traditionally made of wood, but there are also known handling pallets of plastic, generally obtained by injection molding.
- plastic handling pallets may be mentioned the known embodiments of the French patent documents FR-2070367, FR-2172412, FR-2259023, BR-25670 / FR and also by the documents WO-96 / 24529, US-5341748, DE-2306869, DE-2720364, EP-231792, EP452726 and finally AT-307980.
- the plastic pallets In order to achieve a light achievement (between 10.76 kg and 13.7 kg), and allowing the evacuation of water or other liquids, the plastic pallets have, in most cases, a plate having a perforated structure.
- the openings in the tray may have the shape of elongated slots as shown in some of the aforementioned documents (FR-2,070,367, US-5,341,748). These slots can be oriented either all in one direction, so parallel to each other, or in two perpendicular directions.
- the plastic pallet trays have openings of square or rectangular shape, forming a grid or a grid (see in particular FR-2,259,023 and WO-96/24529 cited above).
- Patent document EP1190953 discloses a plastic handling pallet plate having a "honeycomb" type openwork structure. This "honeycomb" type structure meets the criteria of lightness and resistance mentioned above.
- the honeycomb-like open structure of the aforementioned document has stress concentration points, in the vicinity of the feet, likely to become breaking points of the pallet.
- the present invention aims to improve the overall strength of current plastic pallets handling without increasing their weight.
- the object of the present invention is to improve the distribution and the transmission of forces in areas with high mechanical stresses and thus to avoid stress concentration areas including the feet of the pallet.
- the subject of the invention is a plastic handling pallet comprising a substantially rectangular upper plate and feet or studs protruding under the plate, the upper plate having a honeycomb-like perforated structure, characterized in that the "honeycomb" openwork structure completely covers the surface of the upper plate and extends into the feet of the pallet.
- the "honeycomb" type structure results from cylinder-shaped knots delimiting openings, which are distributed in staggered rows and which are interconnected by partitions or arms. oblique delimiting with the nodes other openings substantially octagonal.
- the thickness of the partitions and / or knots can be increased to increase the strength of the pallet handling.
- one or more additional partitions connect nodes and are oriented in the longitudinal direction or in the transverse direction of the upper plate.
- partitions oriented in the longitudinal direction in order to increase the strength of the pallet by increasing the transmission of forces.
- the weight of the pallet remains substantially the same.
- the feet are provided on their outer surface with reinforcing ribs substantially in the shape of a triangle and intended to protect the pallet from lateral shocks.
- This "honeycomb" openwork structure completely covering the surface of the upper plate and extending into the feet of the pallet, is sufficiently solid to allow the pallet to hold even in areas with high mechanical stresses.
- the relief obtained from the pallet is maximum.
- European standards and ISO 8611-1-1997 (F) are respected.
- the mesh of this structure can be thin enough to allow the storage of small objects and small parts on the pallet, ensuring their support and avoiding their sliding.
- the fact that the apertures of the perforated structure extend completely through the plate and the feet allows a flow of fluids and a good preservation of the load on the pallet.
- a pallet with soles more particularly a pallet whose feet, arranged in rows, are interconnected at their base by elongate soles
- the soles also have a structure perforated in "honeycomb" identical to that of the tray, the openings in the perforated structure of the soles being oriented in the plane defined by the tray of the pallet to avoid retentions of water or various liquids.
- a particular embodiment of the pallet according to the invention provides soles having an inclined lateral edge forming a ramp.
- the "honeycomb" perforated structure that extends into the feet helps to optimize the cooling of the pallet during its injection molding and thus obtain an injection cycle of less than 100 seconds.
- the invention is applicable to various types of plastic pallets: single-use pallets or reusable pallets, pallets stackable or not, pallets with single feet or pads, or pallets with soles, etc ...., these pallets can beings naturally of any size, in particular of standardized dimensions.
- Figure 1 is a partial top view, in perspective of a pallet according to the present invention.
- Figure 2 is a partial bottom view, in perspective of a pallet according to the present invention.
- Figure 3 is a side view of the pallet.
- FIG. 1 shows a plan view of a corner of the plastic handling pallet, generally designated by the reference numeral 1.
- the pallet 1 comprises a perforated top plate 2 of rectangular shape for example, it is understood that that the corner of the pallet illustrated in Figure 1 represents a corner of the upper plate 2.
- nine feet or studs 3 distributed in three parallel rows of three feet 3, protrude.
- the two outer rows extend substantially along the longitudinal edges of the pallet 1 and the middle row longitudinally passes through the pallet 1 in the middle.
- the three legs 3 of each row are interconnected at their base by an elongate soleplate 4.
- FIG. 1 thus illustrates part of the honeycombed structure covering the entire plate 2. Since the pallet 1 under consideration is provided with flanges 4, each flange 4 also has a perforated structure "Honeycomb" as shown in the figure 1. The pallet is obtained by injection molding and is made in one piece.
- the perforated "honeycomb" structure of the plate 1 is formed by vertical partitions 5 regularly arranged in rows and columns to form a grid defining first openings 6 which extend completely through the plate 2 and through nodes 7. of cylindrical shape and arranged respectively at the intersections of the grid.
- the nodes 7 form second openings 8 which extend vertically through the plate 2.
- the vertical cylindrical partition forming the wall of the nodes 7 is designated 9.
- the vertical partitions 5, 9 delimit the openings 6 and 8, repeating in a regular geometric pattern, in the longitudinal and transverse directions of the pallet 1.
- the cylindrical partitions 9 constituting the walls of the nodes 7 traverse vertically the plate 2 so as to delimit the openings 8.
- the multiple nodes 7, thus formed are distributed in staggered rows on the entire plate 2, and are interconnected by the oblique partitions 5.
- These partitions 5 are oriented in oblique directions, at 45 ° with respect to the longitudinal and transverse directions of the pallet 1.
- the combination of the partitions 5 and 9 delimits the first openings 6, of substantially octagonal shape, each opening 6 having four sides formed by quarter walls 9 belonging to four different nodes 7, and four other sides formed by the four oblique partitions 5 connecting the four nodes 7.
- the partitions 5 and 9 are interposed to form an opening 6.
- Figure 1 is a partial perspective view intersected by a median plane perpendicular to the upper plate 2 and cutting the row of three feet 3 of the middle of the plate 2 in two, to show the detail of the inside of the feet 3.
- a foot 3 is delimited by a vertical wall 11 having substantially the shape of a parallelepiped and extending from below the plate 2 to the level of the lower surface of the flanges 4 so that the pallet 1 rests on the feet 3.
- the cylindrical partitions 9 connected by the oblique partitions 5 defining the structure described above extend vertically from the plate 2 in the feet 3 and are delimited by the vertical wall 11, as shown in Figure 1.
- the forces are thus transmitted and distributed homogeneously, avoids the stress concentration points and therefore the risk of rupture of the pallet 1.
- the honeycombed structure of the soles 4 is identical to that of the plate 2.
- the openings 6 and 8 in the soles 4 are oriented in the plane defined by the plate 2.
- the oblique partitions 5 in the plate 2, in the soles 4 or in the feet 3 form arms which converge towards the nodes 7 of the honeycombed structure so that the pallet 1 is particularly resistant to the forces of traction and bending, as well as crushing and shocks, even in the intersection zone of the feet 3 and the plate 2.
- a bottom view of the plastic handling pallet is shown.
- the vertical wall 11 extends well below the plate 2 to the level of the lower surface of the flanges 4 so that the pallet 1 rests on the feet 3.
- the inside of the feet 3 has the same honeycombed open structure as that described above for the upper plate 2. It is therefore understood that the cylindrical partitions 9 connected by the oblique partitions 5 extend vertically from the plate 2 in the feet 3.
- the soles 4 are also provided with a perforated structure in "honeycomb", as shown in Figure 2.
- FIG 3 there is illustrated a side view of the pallet 1 comprising a plate 2, feet 3 and flanges 4 as described above.
- each leg 3 is provided, on the outer surface of its wall 11, reinforcing ribs in the form of vertical walls 12 having substantially the shape of a right triangle whose right angle is at the base of the foot 3.
- the triangular walls 12 provide protection against external lateral impacts.
- the walls 12 leave a space between the feet 3 and the edges of the plate 2 so as to facilitate the "filming" of the products stored on the tray 2 and thereby obtain excellent product hold with pallet 1.
- partitions are added in a longitudinal and / or transverse direction in areas of high mechanical stress.
- the resistance of the pallet 1 is increased.
- the soles 4 extend transversely to connect the three rows of three feet 3 at the outer edges of the pallet 1 so that it is possible to stack the pallets so more stable.
- Such a pallet 1 is particularly light.
- the weight can be reduced to about ten kilograms, or even less, whereas the usual weight of a plastic pallet, of the same dimensions, is the same. order of 25 kg.
- the thickness and the height of the walls 5 and 9 are chosen to be equal to approximately 3.5 mm and 30 mm, for example.
- the height of the soles 4 was chosen equal to about 20 mm.
- the invention is not limited to the sole embodiment of this plastic handling pallet which has been described above, by way of example; it embraces, on the contrary, all variants respecting the same principle.
- it is not departing from the scope of the invention by modifying the detail of the shapes of the honeycomb structure; adapting the invention to pallets of greater or lesser dimensions, with more or fewer feet; by applying this invention to pallets without soles and stackable, in which case, of course, the perforated honeycomb structure will only concern the plate and the feet of the pallet; more generally, by applying the invention to all handling products with tray or floor and feet, similar to pallets, for example crates-pallets; by making pallets, or the like, of any suitable plastics material.
