Definitions
- the present invention relates to a modular pallet, and more particularly to an improved modular pallet which is readily configurable into virtually any desired size with ample strength to support different loads.
- Pallet is well known for its usage as a loading platform for storage and conveyance of products in quantity. Pallet provides a stable base for a manufacturer or distributor of a product to stack items thereon allowing for ease of movement by use of a forklift or pallet jack.
- storage pallets have been constructed of wood materials in conventional configurations. Wooden pallets enable to provide years of service if not exposed to severe conditions or unusual loading situations that could cause crumbling or collapse of the wooden frames or components. Although the wooden pallets have adequate strength for years of service, they are relatively heavy which add significantly to the expenses of handling and transportation of goods. Moreover, wooden pallets are in constant need of repair which resulting in an additional expenditure of capital as well as labour.
- wooden pallets Another problem with wooden pallets is that insects or other pests can easily burrow into the wood and be transported into and infest uncontaminated storage area. Such insects or pests may continue to reproduce and thrive in the wooden structure of the wooden pallet. Moreover, the exportation of goods on wooden pallets is prohibited in some countries due to concern of introducing pests such as wood beetles. Additionally, wooden pallets allow for absorption of water which adds substantially weight to the pallets, and yet reduces stability and durability. In addition, increase of humidity can also stimulate bacterial or fungal growth in the pallet which may lead to hygiene issues.
- metal pallets such as those typically formed by aluminum.
- Metal pallets are known for their durability under normal circumstances.
- aluminum pallets are expensive to manufacture and once damaged, cannot be readily repaired.
- any interim damage occurs such as breach of welded parts, the pallet could have a catastrophic failure under a loaded condition. This could cause injury to operating personnel or damage to the materials positioned on the pallet.
- the present invention relates to an improved modular pallet for supporting loads.
- the modular pallet includes: a) three spaced apart base members, each having pillars integrally linked by upper girders and lower girders; b) a pair of supporting ribs having a pair of rigid adjoining sections integrally connected by a beam to define a channel; c) a platform having a load-bearing plate with side walls wherein the longitudinal side walls adapted to be matched with the associated parts of the supporting ribs and base members; and d) a plurality of locking members, each having a rigid body integrally extended from a head section.
- Each side faces of the pillar of the base member facing toward another adjacent base member is provided with at least one locking slot adapted to facilitate the assembly of the supporting ribs and/or the base member.
- the locking slots of the pillars serve to receive the locking members by means of insertion.
- each locking slot of the pillar is provided with a female interlocking connector.

- the recesses of the base member serve to interlock the platform to the base member by means of stoppers.
- each rigid adjoining section of the supporting rib is provided with at least one locking slot.
- each locking slot of the rigid adjoining section is provided with a female interlocking connector.
- the female interlocking connector can include but is not limited to a locking tongue.
- the outward faces of the adjoining section are also provided with a pair of protrusions and serve to be inserted into their corresponding openings on the pillars of the base member.
- the supporting rib is further provided with indented accesses and retaining portions along the longitudinal side walls of the beam collectively operable to receive the platform.

Description
MODULAR PALLET
FIELD OF INVENTION
The present invention relates to a modular pallet, and more particularly to an improved modular pallet which is readily configurable into virtually any desired size with ample strength to support different loads.
BACKGROUND OF INVENTION
Pallet is well known for its usage as a loading platform for storage and conveyance of products in quantity. Pallet provides a stable base for a manufacturer or distributor of a product to stack items thereon allowing for ease of movement by use of a forklift or pallet jack. Traditionally, storage pallets have been constructed of wood materials in conventional configurations. Wooden pallets enable to provide years of service if not exposed to severe conditions or unusual loading situations that could cause crumbling or collapse of the wooden frames or components. Although the wooden pallets have adequate strength for years of service, they are relatively heavy which add significantly to the expenses of handling and transportation of goods. Moreover, wooden pallets are in constant need of repair which resulting in an additional expenditure of capital as well as labour.
Another problem with wooden pallets is that insects or other pests can easily burrow into the wood and be transported into and infest uncontaminated storage area. Such insects or pests may continue to reproduce and thrive in the wooden structure of the wooden pallet. Moreover, the exportation of goods on wooden pallets is prohibited in some countries due to concern of introducing
pests such as wood beetles. Additionally, wooden pallets allow for absorption of water which adds substantially weight to the pallets, and yet reduces stability and durability. In addition, increase of humidity can also stimulate bacterial or fungal growth in the pallet which may lead to hygiene issues.
Wooden pallets also have a significant disadvantage in that they do not interlace or readily stack. Thus, if a number of wooden pallets are to be placed on top of each other, there is a possibility for the pallets to tip over especially in the event that any of the pallets within the stack slips away from a squarely stacked position above the underlying pallet. Moreover, conventional wooden pallets occupy considerable space.
In the past, woods are relatively inexpensive and simple to work with material. However, as lumber prices have been increased along with the concern of depletion of natural resources, alternative materials have been explored.
An alternative to wooden pallets includes metal pallets, such as those typically formed by aluminum. Metal pallets are known for their durability under normal circumstances. However, aluminum pallets are expensive to manufacture and once damaged, cannot be readily repaired. In the event that any interim damage occurs, such as breach of welded parts, the pallet could have a catastrophic failure under a loaded condition. This could cause injury to operating personnel or damage to the materials positioned on the pallet.
Yet another material used for the construction of pallets is plastic. Plastic is capable of being sterilized, and is resistant to most environmental conditions. However, a plastic pallet is even more difficult to repair than that of metal if it is not modularly constructed. Should a portion of the pallet become damaged, the entire pallet becomes non functional.
Many improvements to plastic pallets have been carried out by means of which the pallets are of modularly constructed. However, some of the existing modular formed plastic pallets are found to be unsatisfactory because of their constructions appear to have certain drawbacks such that they have not become widely used. Moreover, some of the existing modular formed plastic pallets are relatively complex in construction, lack strength, and yet difficult in assembly.
In view of these and other shortcomings, it is desirous to provide an improved modular pallet which facilitates readily configurable into virtually any desired size with ample strength to support different loads. The present invention provides an improved modular pallet which is simple in construction, leading both to economy of manufacture and simplicity in assembly. Moreover, the present invention facilitates readily assembling and/or disassembling of component parts without the use of special tools, and yet any damage of component parts is replaceable at competitive costs. In addition, the component parts, fully and/or partially assembled pallets may be conveniently and safely nested or stacked to minimize the storage space.
The improved modular pallet of the present invention and its combination of elements or parts thereof will be described and/or exemplified in the detailed description.
