Field of use of the invention

The invention relates to support elements that can be used as a substitute for wooden beams, boards or planks. These support elements are preferably made of corrugated paper and have a low weight with high strength. These support elements can be used for fastening, ensuring stability or as a support for various objects.

This invention relates to pallets or load-bearing devices that can be made from corrugated paper or similar materials that are recyclable. These pallets are used to move goods, materials, etc. and being lighter in this way reduces transport costs. The design of this pallet provides excellent stability, and also allows you to minimize cost.

BACKGROUND OF THE INVENTION

Industries such as transportation and manufacturing have been using products such as beams, boards or planks as supports, spacers and dividers for various goods or materials for a long time. Despite the fact that wooden products are durable, they have numerous disadvantages.

One of the drawbacks, in particular, is that the wood is relatively dense and therefore heavy. The weight of wood products increases transportation costs and reduces the amount of materials that can be transported. Another disadvantage is that the surface of the tree is rough and usually uneven, which can lead to damage to the finish of materials, especially fragile materials that abut or rest on it. In addition, when exposed to moisture, wooden products can warp, losing their shape and becoming unsuitable for intended use.

A pallet is a mobile platform, usually containing a flat horizontal element that can be used as a base element for stacking, storing, moving and transporting materials or goods. Typically, pallets are made of wood using nails or staples. Recently, pallets have also been made from paper-based materials and plastics. Pallets typically have openings in the structure to accommodate a forklift of a forklift truck or the like and enable the pallet to be raised from the floor.

US Pat. No. 5,269,219 relates to the construction of a pallet designed for the transport of goods made of a paper product, consisting of a support floor, a top cover sheet with convex jumpers that provide fastening and attachment to supports, a bottom sheet glued to the floor, which provides a solid surface for joining the supports, and the supports themselves are spaced apart from each other to the sides and to the appropriate height to ensure the passage of the forks uzchika or manual lift.

US 5,595,125 relates to the construction of a lightweight recyclable tray made of corrugated paper formed by a plurality of corrugated paper supports spaced across the pallet, each of which is made by wrapping a continuous inner sheet of corrugated paper that is itself glued to the underside of a reinforced corrugated paper top flooring and to the upper side of the corrugated paper backing.

US patent 5784971 relates to the design of a collapsible pallet, which contains at least a pair of longitudinal beam elements and at least a pair of transverse beam elements made of corrugated paper material. Each longitudinal beam element includes a portion of the surface (outer) plate, from which many folded sections of the side walls extend downward, and at least one portion of the shelf is essentially in the same plane. Said portion of the surface (outer) plate has a plurality of upper slotted holes made through it, which communicate respectively with a plurality of lower slotted holes made through through said sections of the side walls. Each transverse beam element contains a portion of the upper plate from which many folded portions of the protruding plate extend downward. Each part of the protruding plate has a slotted opening that defines a pair of protruding sections of the protruding plate. Each transverse beam element is connected to the longitudinal beam elements in a cross-over manner, with portions of its upper plate partially overlapping at least one of the surface sections of the bar of the longitudinal beam elements, and at least one protruding section of each part of the protruding plate inserted into the upper slot hole of the section surface plate of the longitudinal beam element.

US Pat. No. 5,934,202 relates to a paper pallet that comprises a lower deck made of corrugated cardboard, an upper deck made of corrugated cardboard, a plurality of paper blocks arranged in a longitudinal and transverse direction in rows and forming a connection between the lower deck and the upper deck, and also a plurality paper intermediate elements, respectively attached between paper blocks and one of the decks - lower or upper, and each of these intermediate elements has an elongated a base attached between one of the decks - lower or upper, as well as one of the rows of paper blocks and pairs of intermediate flaps extending in two directions from two opposite long sides of this oblong base and respectively attached to the corresponding row of blocks on two opposite sides.

US patent 6357364 relates to a paper pallet, which contains the support blocks, the top panel and the winding. Such support blocks have a cellular structure, for example, a honeycomb, in particular a hexagonal one. The upper gasket is made of corrugated material and mounted above the support blocks. The winding is also made of corrugated material and wraps with direct contact the upper and side surfaces of the upper strip, also wrapping with direct contact at least two side surfaces of the support blocks.

These well-known paper-based pallets have a rather complex structure that is inefficient in terms of manufacturing cost, and also relatively bulky and heavy. Pallets of known design are laborious to manufacture and often not fully recyclable.

Summary of the invention

Supporting elements are proposed that can be used as a substitute for wooden struts, supports or the like. These support elements are preferably made of corrugated paper and have a high coefficient of strength with respect to weight. This support element is typically made of one-sided corrugated material, rolled around a central region or core, to form an elongated element having dimensions similar to a wooden product that it can replace.

In another embodiment, an object of the present invention is to provide a pallet, preferably made of corrugated paper, which, while lightweight, has sufficient strength to support the materials or goods to be transported. In most cases, this pallet can be disposed of and does not create any harmful effects on the environment.

Another objective of this invention is to provide a pallet design that is easily adaptable to specific requirements and which can be manufactured in large quantities to meet changing customer needs.

The pallet of the present invention generally comprises an upper flooring element, a lower flooring element, as well as a plurality of supporting elements interconnected. The upper flooring element and the lower flooring element are independent from each other in a horizontal plane essentially parallel to each other, as well as the surface of the earth. Said support elements comprise a single continuous winding of corrugated paperboard, which is preferably one-sided and has a continuous layer of paper with reinforcing corrugations attached to it. Mentioned continuous winding of support elements provides strength and rigidity of the pallet.

In one embodiment, the pallet is made of two or more support elements that extend substantially along the length or width of the flooring elements and provide two-way access for the forklift. In another embodiment, the support elements have access holes perpendicular to the longitudinal axis of these elements, so that the pallet can be accessed from all four sides for lifting and / or moving.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the pallet and its corresponding assemblies of this invention are described separately using the accompanying drawings, in which like reference numbers indicate like or corresponding parts in the attached figures.

Figure 1 shows the pallet 10 according to this invention, which contains the upper or covering element 20 of the flooring, the lower element or base 30 of the flooring, as well as many supporting elements 40. The supporting elements are fixed in predetermined positions between the elements of the flooring using fixing means such as adhesives, tape, fittings or the like, with preference in favor of white glue.

The upper flooring element 10 typically serves as a support or bearing surface for goods or materials intended to be stored on and / or transported on a pallet. This upper flooring element is preferably made of a single sheet of corrugated cardboard or paper. Corrugated paper can be three-layer, five-layer or seven-layer. As you know, three-layer corrugated sheets are formed from two outer sheets 22, 24, connected by a layer of corrugations 26, as shown in Fig.3. Separate five-layer or seven-layer corrugated sheets respectively contain two or three layers of corrugation, which are respectively separated by a single layer of thin paper or sheet material, with a layer of paper or sheet material covering the outer surfaces of the outer corrugations. Accordingly, five-layer or seven-layer corrugated sheets have alternating layers of corrugations and thin paper layers, as well as paper layers, which are the outer surface of these sheets. The corrugations can be described as having a repeating S-shaped configuration or a wavy profile. The height of the corrugations, that is, the size from the top to the bottom, as you know, can vary and can be of the following sizes: A, B, C and E, but not limited to them. When using five or more layers of corrugated sheet in one sheet of corrugated paper, different sizes, that is, different corrugation heights, can be used, with sizes B and C being preferred for five-layer sheets, and A, B and C or A, C and C are preferred for seven-layer sheets. The corrugations of this corrugated sheathing form hollow tunnels or straw-like passages and connect the remaining layers to each other.

The upper floor element 20 is a flat structure having a predetermined length and width, in a size range generally from about 12 inches (304.8 mm) or 14 inches (355.6 mm) to about 50 inches (1270 mm), and preferably from about 30 inches (762 mm) or 40 inches (1016 mm) to about 48 inches (1219.2 mm).

The main plane formed by the upper element of the flooring is essentially horizontal and parallel to the lower element of the flooring, and is configured to be installed parallel to the surface of the earth. The top element is mounted at a predetermined distance, typically from about 3 inches (76.2 mm) to about 5 inches (127 mm) or 6 inches (152.4 mm) from the bottom floor element 30.

The lower flooring member 30 may be of the same size, type and construction as the upper flooring member 20. Depending on the intended purpose of the pallet, the corrugated sheets of the upper and lower flooring elements can be the same or different, for example, both from three-layer corrugated paper or one element is three-layer, and the other is seven-layer, and the like. The bottom element of the flooring is in contact with the ground or rests on it. The planes formed by the upper and lower flooring elements, as already noted, are essentially parallel, and thus provide a flat surface for goods or materials.

The support elements or beams 40 of the pallet provide both strength and structural rigidity. Each individual support element is formed from a single continuous piece of corrugated paper, for example, of a one-sided type. Alternatively, a plurality of pieces can be used, generally such as about 10 or about 8 or less, preferably about 6 or about 4 or less, and preferably about 3 or about 2, and they are joined at their ends to one another either with or without the help of connecting means, such as adhesive, and wound in the same way as a single solid piece of corrugated paper. This solid piece of a given height is wound or wrapped around itself to form a given length and width, or thickness. The support member 40 is preferably made of one-sided corrugated paper containing a single layer of paper with corrugations extending thereon. Glue or other adhesive is used to bond the wound continuous layers to each other. In the process of forming the support element, the adhesive is preferably applied to the outer edges of the corrugation, which will be in contact with the next paper layer. Such continuous winding has a continuous character of alternating layers of corrugation and gasket, or paper.

The overall dimension of the support member 40 may vary in height, typically in the range of from about 3 inches (76.2 mm) to about 5 inches (127 mm) or about 6 inches (152.4 mm), preferably from about 3.5 inches (88 , 9 mm) up to about 4 inches (101.6 mm), and preferably about 3.5 inches (88.9 mm); in width, typically from about 2 inches (50.8 mm) to about 4 inches (101.6 mm) or about 6 inches (152.4 mm), preferably from about 2 inches (50.8 mm) to about 3 inches (76.2 mm), and preferably from about 2 inches (50.8 mm) to about 2.5 inches (63.5 mm); and in length in the range typically from about 12 inches (304.8 mm) or 14 inches (355.6 mm) to about 50 inches (1270 mm); preferably from about 40 inches (1016 mm) to about 48 inches (1219.2 mm), and preferably from about 46 inches (1168.4 mm) to about 48 inches (1219.2 mm).

The corrugations of the support element are located along the height of this support element to ensure strength. In this case, the flooring elements cover the open ends of the supporting element, completely covering them. The overall dimensions of the support element may vary, they depend on the intended purpose and the weight for which this pallet is designed.

Often, the support member can extend substantially along the entire length of the pallet from one side, or end, to the other. The number of supporting elements used between the flooring elements also depends on the weight for which the pallet is designed, and is preferably approximately 2 or approximately 3 and up to 6 supporting elements in the pallet.

In a preferred embodiment, the corrugation 26, 36 of the floor elements 30, 20 are arranged in a direction perpendicular to the length (rather than the width) of the support elements, thereby providing strength to the pallet, as shown in FIG. 3. That is, the corrugations of the supporting elements are perpendicular to the corrugations of the flooring elements. This configuration is also shown in FIG. 2. It ensures that the pallet is lightweight and recyclable with a solid and stable construction.

As shown in at least FIG. 2, the support members 40 preferably have rounded or curved end parts 42. These curved end parts are configured to guide the forklift of the forklift into the pallet. That is, such curved end parts ensure that the forks enter the passages formed between adjacent support elements.

Figure 3. is a partial sectional view of the pallet of the present invention, in particular, showing the orientation of the corrugations of the corrugated elements. The corrugations 26 of the upper floor element 20 are oriented in a direction perpendicular to the length of the support element 40. This upper floor element is a three-layer corrugated paper sheet having outer layers or paper sheets 22 and 24 connected by corrugations 26. Similarly, the lower floor element contains external paper layers or sheets 32 and 34 connected by means of corrugations 36, which are also oriented perpendicular to the length of the support element 40.

Figure 4 shows the support element 40, which can be used to create a four-way pallet. The support member 40 has at least two cutouts 44 that extend completely through the width of this support member. The size of these windows or cutouts can be varied and at least large enough to fit the forklift. Cutouts 44 provide the pallet of the present invention with the ability to be accessible from all four sides to lift and move it.

In another embodiment, as shown in FIG. 2, the lower flooring member 30 may have hoist holes 50 made therein to accommodate the wheels of the manual hoist. The holes 50 for the lift can be of any shape or size and are usually at least larger than the size of the wheels of the manual lift. The holes 50 for the lift provide the use and lifting of pallets using manual lifts, which are generally handled. Hand lifts typically have wheels on the forks to roll on the ground. The holes 50 for the lift are made with the possibility of free movement of the wheels of the manual lift, since the contact of these wheels with the pallet 10 is prevented due to the presence of holes for the lift.

In addition, one or both of the upper and lower flooring elements can be treated with oil and / or water-repellent compositions in a manner known in the art and literature to extend the life of the pallet. The pallets of the present invention made of corrugated paper are fully recyclable and thus environmentally friendly. The pallet design is also insect resistant.

In another embodiment, the support member or article may be used separately, that is, not assembled with a pallet. The support element is used as a substitute for wood, but is not limited to such areas of use as dividers in stacks, supports, spacers, spacers, pads for stability and the like.

As indicated above, these support elements 40 are usually oblong, as shown in at least FIG. In addition to the above sizes of supporting elements used in the construction of the pallet, the design of the supporting element may be arbitrary. That is, the dimensions of the support elements are selected according to the intended purpose. For example, in one embodiment, the support member is used as a spacer on the floor of a caravan or railroad car, or it is used to fit between adjacent loads or rows of loads. This support member 40 is approximately 0.50 inches (12.7 mm) × approximately 2 inches (50.8 mm) × approximately 2 inches (50.8 mm) to approximately 8 inches (203.2 mm) × approximately 8 inches (203.2 mm) × approximately 50 inches (1270 mm), or approximately 100 inches (2540 mm), or from approximately 1 inch (25.4 mm) × approximately 2 inches (50.8 mm) × approximately 2 inches (50.8 mm) to about 6 inches (152.4 mm) × about 6 inches (152.4 mm) × about 50 inches (1270 mm). In other embodiments, the support member may also be manufactured according to typical specifications for wooden planks, such as 2 inches (50.8 mm) × 4 inches (101.6 mm), 4 inches (101.6 mm) × 4 inches (101, 6 mm) or 2 inches (50.8 mm) × 6 inches (152.4 mm) in essence of any length required. In one embodiment, two or more of these support elements are glued together, that is, with each other, when the elements are on top of each other or in another similar way, if you want to provide an increased surface area.

And although the relative dimensions of the support element may change, the method of constructing it is generally the same. This support member is formed as a winding or roll of corrugated paper. This winding is provided in the form of a spiral winding, more precisely a flat oblong winding or roll. As already mentioned above, the support element is preferably formed of one-sided corrugated paper having a layer of corrugated paper of a fixed thickness, and the corrugation layer is attached to it usually by means of an adhesive by known methods. Such an assembled rectangular support element, flat with a spiral winding or a rounded end, has alternating layers of paper sheets and corrugation.

As indicated above, the corrugations can be of sizes A, B, C or E, but are not limited to them. As is known, the paper layer of corrugated paper typically has a range from about 0.023 lb / ft ² (112.3 g / m ² ) to about 0.090 lb / ft ² (439.4 g / m ² ) of medium or packaging board. Advantageously, the weight or thickness of the paper is precisely selected to suit the intended purpose, and if a more powerful support or strength is required, a denser grade of paper is used. Thus, the support elements can be selected to order in accordance with a specific purpose.

The support element 40 is usually performed in the following manner. From the starting point 41, the corrugated paper of a predetermined height extends to a predetermined length “X”, thereby forming a central region, or to a core 42, preferably in a straight line so that when a predetermined number of layers is wrapped or wound around this central core, a support element is formed having a total length L and a width W. When the corrugated paper is straightened to the length “X”, the paper is then folded or folded either clockwise or counterclockwise, and fed back to ol core from attaching to the central core 42. When the starting point 41 is reached, the corrugated paper is wrapped around it. This process is repeated until the central region is wrapped with the required number of layers.

Each layer of paper of the support member is preferably adhered to the adjacent layer by an adhesive. As shown in FIG. 4, corrugated layers and sheet layers are interleaved. The end 43 of the corrugated paper may be substantially located at any point on the outer surface of the support member without limitation, as shown in FIG. 4. Although this support element can be made of one whole piece of corrugated paper, it should be clear that several pieces with ends adjacent to the butt or to some extent overlap can be used.

The support member of this invention has excellent strength. Its winding design provides rigidity and stability to the support member. The curved end portion 45 is very stable and helps to prevent separation of the layers from each other. This support element is used in all cases where a spacer, support and the like are needed. The support element provides shock absorbing properties and absorbs vibration that may occur during transport, thereby reducing damage to the product. In addition, this support element does not have nails, chips or other protrusions harmful to products that can be mounted on them. These support elements are recyclable and capable of being converted back into pulp, which reduces the generation of waste in landfills.

Example 1

A two-way pallet according to the invention was made having an upper deck, a lower deck and four support elements. Both the top deck and the bottom deck were 40 inches (1016 mm) wide by 48 inches (1219.2 mm) long and were formed from one three-layer corrugated paper sheet with a density of 0.075 lb / ft ² (366.2 g / m ² ). Each of the supporting elements was made of one sheet of single-sided corrugated paper. Glue was applied to the edges of the corrugation, and then one whole piece of one-sided corrugated paper was wrapped around itself, forming a support element 3.5 inches (88.9 mm) high, 48 inches (1219.2 mm) long and 2 inches wide (50 , 8 mm). Two support elements were installed at the ends in width, and the remaining supports were located between them at equal distances from each other. Flooring elements were attached to supporting elements using ordinary white glue.

A load of 7,200 pounds (3,265.9 kg) was installed on a pallet. The pallet retained its initial shape and size without deforming under the pressure of this weight for two weeks when the load was removed.

Example 2. Compression Testing

A pallet having the above construction and dimensions, as in Example 1, was installed in a calibrated hydraulic press. Then, a force was applied to the upper and lower elements of the pallet flooring, which increased stepwise. The pallet withstood the loss of strength withstood a load of 17,000 pounds (7711 kg).

The scope of the present invention is limited not by the best option and preferred embodiment, not given in accordance with the requirements of patent law, but by the scope of the attached claims.
