[0001] REMOVABLE PALLET
[0002]
[0003] The present invention, as the name implies, refers to a removable pallet comprising a series of skates and a series of crossbars where both are firmly joined by geometries and pressure adjustments without the need for any other element or material of Union.
[0004]
[0005] For fastening the crossbars to the skates, no screws or any other type of joint parts are required, but the geometry of the pieces is sufficient to keep them solidly joined.
[0006]
[0007] The sector of the technique to which the invention belongs is that of transportable structures.
[0008]
[0009] BACKGROUND OF THE INVENTION
[0010]
[0011] Since ancient times, pallets have been used to transport loads, however such pallets must make several trips without cargo, which, sometimes, due to their volume, makes their recovery uneconomic.
[0012]
[0013] It is also not easy to sell new pallets over long distances because the route between the manufacturer and the first user is also made without load.
[0014]
[0015] To favor the transport of more pallets in the same transport unit, such as a truck or a container, removable pallets have been devised, so that, once they have fulfilled their function with the load in a transport, they can be disassembled to optimize space.
[0016]
[0017] The removable pallets also favor the replacement of broken pieces because in non-removable ones, the breakage of a piece makes the pallet unusable in most cases with the economic and environmental cost that this entails.
[0018] Among the background of removable pallets we find the following:
[0019]
[0020] The utility model ES245986 refers to a removable pallet, although in order to give rigidity to the assembly it requires that the longitudinal elements be joined together both superiorly and inferiorly, which raises the number of pieces to be used in the assembly.
[0021]
[0022] The utility model ES1018770U, refers to a removable pallet whose different elements are joined together by a series of studs crossed by rods, therefore requiring such connecting elements in addition to the longitudinal and transverse parts that constitute the structure itself .
[0023]
[0024] The utility model ES1033284U refers to a removable pallet whose pieces are joined together thanks to a sandwich arrangement where the center piece has been added protrusions suitable for assembling with holes made in the outer parts. This solution presents some manufacturing problems essentially derived from the protuberances that must be attached to the slat at a later stage as well as transport problems since the existence of the protuberances prevents optimizing the spaces in the transport when the pallet is removed.
[0025]
[0026] The utility model ES1018770U refers to a removable pallet configured on the basis of a horizontal platform that has cutouts as a flange being that these tabs must be able to deform until adopting a vertical position, which limits the materials to which this can be applied technical solution
[0027]
[0028] European patent EP0516681 published in Spain as ES2093698 refers to a removable pallet consisting of two hollow metal skates, facing each other whose facing faces have a series of holes suitable for introducing and fixing crossbars that have grooves on their underside of disposition and suitable form to settle on the inner vertical walls of said skates. This technical solution requires that the stringers be metallic.
[0029] US Patent US2007 / 0221537 refers to a three-dimensional structure made from various pieces that are assembled together where such pieces are made or at least filled with several layers of cardboard or corrugated paper. This patent requires, for its execution, several different types of parts. On the other hand, assemblies generate protrusions in the structure that make handling and storage difficult.
[0030]
[0031] US patent US8113129, refers to a pallet formed by different pieces, skates and crossbars, which are assembled together, each of those skates and crossbars being composed of two pieces that, when joined, trap the piece with which it they cross and, in turn, get trapped with it. The assembly thus raised generates protrusions that hinder the handling and storage of the pallet.
[0032]
[0033] US patent US2009 / 0298015 refers to a removable pallet formed by a series of pieces, stringers and crossbars, which intersect forming the pallet, being joined by pressure adjustment and reinforced the union by rods that cross the pieces longitudinally once mounted the pallet. Different parts and rods are required in this patent and, given the way of joining, protrusions are generated that make handling and storage of the pallet difficult.
[0034]
[0035] The Spanish patent P20133046, of the same applicant, refers to a pallet formed by a series of skates and crossbars where the skates, arranged two by two and in opposite position with respect to each other, are closed by trapping the housed cross member pieces. in some grooves of the stringers, thereby generating a solid structure.
[0036]
[0037] The patent EP14741117.7 also of the applicant, refers to another structure, also mountable and removable without the need of accessory elements of screws or adhesives that has skates and crossbars, where such crossbars, all the same, varied their position to fit in recesses or recesses existing in the skates, and where such skates were arranged alternating one in a direction and the next in the opposite, leaving the crossbars caught in the recesses when aligning the skates.
[0038]
[0039] US patent US4077334 refers to a pallet made of aluminum skates and crossbars that fit together by pressure adjustment. In this type of pallet, due to its mechanics, it is not possible to obtain a full load surface, but it must necessarily be left distance between some crossbars and others to allow assembly and disassembly since the crossbars are deformed laterally for snap fit . Another problem that this type of pallet presents is that the pressure or clamp is made by the side of the crossbar, which, being a long piece, can easily lose pressure either by use or by blows, which makes it unusable. In addition it cannot be done in plastic, it must be done in aluminum with the limitations of cost and production of said material as well as the little recommended of its storage in the open air or in maritime transport.
[0040]
[0041] US patent US3878796 refers to a plastic pallet whose parts, skates and crossbars, fit by sliding the crossbars in the stringers as the crossbars have a geometrically complementary section with holes existing in the skates. For the mechanics of this patent it is necessary the existence of a separation between the crossbars.
[0042]
[0043] None of the exposed patents allow to generate a structure that has a complete surface, as is required for certain uses, as well as a quick and simple assembly that can be done piece by piece without excessive effort, all with optimal behaviors resistance in a double sense; Resistance of the pallet that is kept mounted without impact, without being disassembled, as the resistance of each piece that does not deform nor loses its usefulness due to the blows and collisions to which, in normal use, it will be subjected.
[0044] DESCRIPTION OF THE INVENTION
[0045]
[0046] To overcome the above problems, a removable pallet with a full load surface is proposed, formed by a plurality of crossbars, which is assembled without the need for any type of hardware or additional elements to ensure the joints between the parts that compose it.
[0047]
[0048] Obtaining a full load surface is essential for use in certain sectors, and the possibility that it can be disassembled into small pieces is very advantageous for empty transport.
[0049]
[0050] On the other hand the non-existence of screws or other joining materials, facilitates the replacement of a broken piece and its recycling, unlike other pallets where a broken piece forces to change the entire pallet with the economic and environmental cost .
[0051]
[0052] On the other hand, the return to their company of origin is much cheaper because they can be disassembled and take up much less space.
[0053]
[0054] A pallet like the one proposed also has the advantage of being repaired simply by simply changing the damaged part or parts, unlike other types of pallets where the breakage of a part implies the need to change the entire pallet.
[0055]
[0056] This pallet, thanks to its mechanics, can be made in any moderately rigid material although the possibility of being able to do it also in plastic, without reducing its strength and robustness characteristics, is an added advantage.
[0057]
[0058] On the other hand, the simplicity of their joints makes their assembly and disassembly especially simple.
[0059]
[0060] The pallet is built with skates and crossbars.
[0061] Skate call to each of the parts constituting the lower structure of the pallet way of beams that support the loading surface of the same.
[0062]
[0063] Crosspiece call to each of the parts, arranged perpendicularly on the skids are fixed to these and set the loading surface of the pallet.
[0064]
[0065] Each of the skates has, in its upper part, a plurality of anchoring elements comprising one or more rigid stops and one or more flexible stops.
[0066]
[0067] The crossbar pieces have a geometry that allows it while while one of its major sides is trapped by the rigid stops of the skates, its other major side is fixed, either with a flexible stop, by means of pressure adjustment, or with another crossbar adjusting for geometry.
[0068]
[0069] The crossbars, with the exception of the outer crossbars, once installed, are in contact with each other on their sides, generating a full load surface.
[0070]
[0071] In this way, the rigid stops prevent the advance of the crossbars at a point as well as their vertical displacement, while a flexible stopper or an adjacent crossbar prevents the crossbar from backing off and freeing itself from the action of said rigid stopper.
[0072]
[0073] Thus each crossbar is trapped by its major sides. One of its major sides stops with a rigid stop and is trapped by its lower hollow, while the other major side can stop with another crossbar or with a flexible stop.
[0074]
[0075] In a possible execution, which we will call type A execution, each of the crossbars is trapped on one of its major sides by rigid stops and on its other side by the flexible stops, thereby generating the pallet loading surface.
[0076]
[0077] In another possible execution, which we will call type B execution, all the crossbars that make up the surface of the pallet are arranged in identical orientation, and each These crossbars are trapped on one of their major sides by rigid stops and on the other side by the adjacent crossbar, with the exception of the last crossbar that strengthens the assembly in a pressure closure on a flexible stop, thereby generating the surface of pallet load
[0078]
[0079] In another possible execution, which we will call type C execution, one part of the crossbars is arranged in one direction and another part of the crossbars is arranged in the opposite direction. Each of these parts or groups of crossbars behaves mechanically like a type B execution.
[0080]
[0081] In this type of execution type C, the skates can have a double rigid stop, that is, with a lower hollow oriented towards each end of the skate, so that it is in that stop where the groups of crossbars meet, facing each other, extending then each group of crossbars towards the ends of the skate or skates or have rigid stops at the ends of the skates and flexible stops at the central part of the skate.
[0082]
[0083] In any of the executions, the crossbars are in intimate contact with each other, generating a full load surface and contributing, with each other, to the fixation of the assembly.
[0084]
[0085] So that mechanically the pallet can be mounted in the said way, the parts have the following characteristics:
[0086]
[0087] The skate pieces have in their upper part a series of anchoring elements of the skate between which we distinguish rigid stops and flexible stops.
[0088]
[0089] We will call the anchoring elements of the skate generically to the rigid stops and the flexible stops.
[0090] We will call a rigid stop to the anchoring element of the skate, regardless of its geometry, which limits the movement of the crossbar both in the longitudinal direction of the skate and vertically.
[0091]
[0092] To do this, preferably this rigid stop will have a geometry comprising a lower hole, such as an inverted "L" or any geometry that contains it.
[0093]
[0094] We will call a flexible stop to the anchoring element of the skate, regardless of its geometry, which comprises a deformable element that yields to the pressure exerted by the crossbar when it is installed and, when returning to its initial position taking advantage of a hole in the crossbar, occupies that hole and holds the crossbar against the skate.
[0095]
[0096] For this, it can have an arrowhead or roof geometry, or any other that allows the indicated maneuver.
[0097]
[0098] We will call roof to any geometry that presents a diagonal plane in the contact area with the crossbar during its assembly operations.
[0099]
[0100] Rigid stops and flexible stops are aligned and distributed longitudinally on a regular basis across the top of each skate.
[0101]
[0102] The distribution and number of rigid and flexible stops will vary depending on the type of execution desired.
[0103]
[0104] The skates also have some recesses on their sides that cross the body of the skate, being these empties suitable for inserting in them the extensions of transport and stacking machines as can the pallet trucks. So that these empties do not compromise the strength of the structure, they are closed at the bottom by a reinforcement.
[0105]
[0106] The skates are preferably hollow to be lighter, internally comprising a rib structure that gives the skate adequate strength.
[0107] The skates can be made in two pieces, upper and lower, joined together, which reduces manufacturing and facilitates demolding.
[0108]
[0109] The crossbars are flat pieces suitable for staying on the skates perpendicular to them, comprising complementary elements with the rigid stops and flexible stops existing on the skates.
[0110]
[0111] There are two types of crossbars, internal crossbars and external crossbars.
[0112]
[0113] We will call internal crossbars to the crossbars that are arranged between two other crossbars, whatever they are and in close contact with them.
[0114]
[0115] We will call outer crossbars to the start and end crossbars of the loading surface and, therefore, one of its major sides, the outer side, is visible, the other side being, the inner side in intimate contact with the crossbar adjoining, usually an inner crossbar.
[0116]
[0117] The major sides of the internal crossbars have holes that serve interchangeably to be anchored with the rigid stops or with the flexible stops that we will call anchor holes.
[0118]
[0119] In the same way, the internal crossbars also have, on the sides of their major sides, a complementary tongue and groove with the tongue and groove of the adjacent cross members.
[0120]
[0121] The outer crossbars only have this tongue and groove on the side of one of its major sides, specifically on its inner side, while its outer side has blunt edges and lacks tongue and groove, although it does present the anchoring holes.
[0122]
[0123]
[0124] The tongue and groove of a cross member is complementary to the existing tongue and groove adjacent sides of the adjacent cross member (s) being the adjacent cross members inserted between them by the tongue and groove.
[0125]
[0126] Thus, when the pallet is mounted, the crossbars are closely related, being arranged next to each other and inserted together by the tongue and groove.
[0127]
[0128] The crossbars can comprise flanges as a flange to help fix the load.
[0129]
[0130] The tabs of the inner crossbars are located on their smaller sides, specifically protruding from their smaller sides and we will call them side flanges.
[0131]
[0132] The tabs on the outer crossbars are located on the outermost side, specifically protruding from its outer side and we will call them front tabs.
[0133]
[0134] In a preferred embodiment, the crossbars, both external and internal, are hollow to favor their lightness and have internal ribs to give strength to the whole.
[0135]
[0136] The upper and lower surface of the crossbars may have perforations or weft to favor their lightness and, in a proposed execution, both the upper and lower surface of the crossbars have a table, understanding as such a series of alternating longitudinal gaps with zones covered longitudinal, as a fence.
[0137]
[0138] The removable pallet you are interested in can also comprise lower braces arranged perpendicular to the skates that join them together, favoring the robustness of the assembly as well as the use of pallets in roller lines.

[0163]
[0164] DESCRIPTION OF AN EXECUTION MODE OF THE INVENTION
[0165]
[0166] A form of execution is set forth here that is not limiting but expository, since there are, as explained in the description section, different possible configurations and, in addition, the present patent provides technical solutions applicable to other unexposed configurations.
[0167]
[0168]
[0169] The removable pallet comprises a plurality of skates (1) in particular three and a plurality of crossbars (2), specifically six, of which four are internal crossbars (3) and two are external crossbars (6), although the number It may vary in other executions.
[0170]
[0171] The skates comprise in its upper part a series of anchoring elements, specifically six rigid stops (8) and a flexible stop (9) although the total number and of one type and another may vary in other executions.
[0172]
[0173] The rigid stops comprise an inverted "L" shape that generates a lower hole (12), suitable for one of the anchoring holes (13) of a cross member to be housed there, said crossbar being trapped.
[0174]
[0175] The flexible stops (9) have an arrowhead section and have a deformable roof (17) such that the crossbar, in the assembly maneuver, presses downwards vertically on the roof (17) of the flexible stop (9), it causes said roof to give way to the crossbar so that, once the roof finds the appropriate anchoring hole (13), return to its initial position invading the anchoring hole and leaving the crossbar fixed.
[0176]
[0177] In the execution explained here, the pallet is mounted as follows.
[0178]
[0179] The skates (1) are arranged in parallel to the appropriate distance from each other and all oriented in the same direction.
[0180]
[0181] The first cross member that is located, an outer cross member (7), is placed abutting the rigid stops (8) of the end of the skates, inserting such rigid stops into the anchoring holes (13) of the outer side (18) of the outer crossbar
[0182] With the rigid stops inserted in the anchoring holes (13) on the outer side, the cross member is supported on the skates.
[0183]
[0184] The inner side of this outer crossbar is in contact with the following rigid stops, on the part where they do not have a lower gap.
[0185]
[0186] In these rigid bumpers, the following crossbar is inserted, this time an inner crossbar, which is anchored to the rigid bumpers and, when coming into intimate contact with the outer crossbar already arranged on the skates, fastens it thanks to the tongue and groove system (5 ) of both that is complementary in its adjoining sides.
[0187]
[0188] This operation is repeated and thus each crossbar that is located helps to fix the previous one. Finally, another outer cross member is located which, on its inner side, has tongue and groove, contributing to fix its immediately previous crossbar, while with its outer side, presses on the roofs (17) of the flexible stops of that end of each skate, causing these to yield allowing the sliding of the crossbar until the roofs, in a forced position, coincide with the anchoring holes (13) of the outer side of the outer crossbar that is being mounted, and return to their natural position occupying such anchoring holes and being fixed that crossbar and all the others to close the set.
[0189]
[0190] In this way a complete loading surface is configured, without separations between the crossbars.
[0191]
[0192] Each skate is crossed by two emptyings (10) of adequate size so that the extensions of transport and stacking machines are inserted in them as can the pallet trucks.
[0193]
[0194] These recesses are closed at the bottom by a slat (12) that contributes to give robustness to the skate and allows its use on roller lines.
[0195]
[0196]
[0197] The skates are hollow to gain lightness, with a series of internal ribs to give solidity to the skate.
[0198]
[0199] The crossbars, both the exteriors (6) and the interiors (3) are hollow and form a complete surface, without prejudice to the existence of a weft to lighten the assembly.
[0200]
[0201] This surface is bounded by peripheral tabs, there are front (14) and side (16) tabs. These tabs contribute to immobilize the load, avoiding slippage.
[0202]
[0203] At the structural level there are no differences between some crossbars and others, which can be interchangeable, however, for reasons of utility, handling and safety, the outer crossbars (6) have been provided with blunt edges (7).
[0204]
[0205] The pallet can also incorporate, on its lower part, a series of braces (11) joined by geometries to the base of the skates, and that contribute to give solidity to the assembly while facilitating its use in roller lines or in other irregular surfaces, avoiding snagging.
