Description

Interlocking Pallet
FIELD OF INVENTION The present invention relates to a pallet. More particularly, relates to an interlocking pallet formed from at least two connectable subassembly sections.
BACKGROUND OF INVENTION
Interlocking pallets which are formed by interconnecting various modular pallets in a releasable manner have been widely used for storage and supporting loads. Unlike most unitary piece of pallets which are generally restricted to certain loads of length and/or width, such interlocking pallets however provide flexibility in layout configurations and thus facilitate loading of goods with different volumes and/or sizes. Furthermore, such plastic interlocking pallets are durable as any damage to one single modular pallet can be readily removed and replaced by a new modular pallet.
However, there are some limitations observed in the existing pallets with interlocking structures. Weight-bearing capacity of a plastic interlocking pallet will be substantially reduced if it is assembled from more than four modular pallets. These interconnected modular pallets may easily come apart or deformation when it is under load, as there is no positive interlocking means. Besides that, conventional interlocking structures used in the art, for example, pin-and-tail joints, are prone to damage during assembly and they are not easily to be brought into full union.
Therefore, it is the purpose of the present invention to alleviate the aforementioned limitation observed in the traditional pallet structures.
It is yet another object of the present invention to provide a plurality of subassembly sections having an improved interlocking means which is easily to be assembled into pallet structures with different dimensions and configurations.
It is yet another object of the present invention to provide a plurality of joint fastening components to strengthen the structural integrity of an assembled pallet structure, avoiding it from deformation under load, especially when it is being moved. It is yet another object of the present invention to provide a plurality of foot extension structures which detachably secured to the bottom of the pallet and thus elevates the pallet structure from the ground it rests to prevent moisture damage.
Other objectives of this invention will become apparent on the reading of this entire disclosure. SUMMARY OF INVENTION
In one aspect of the present invention, an interlocking pallet s-tructure made of at least two. subassembly sections is -provided. Each subassembly section includes a platform having an . upper surface and a bottom surface;... an interlocking means provided at the periphery of each subassembly section to interlock with the next adjoining subassembly sections; and a plurality of hollow blocks provided -at each outermost corner of the bottom ..surface- o.f .each ..subassembly. section for receiving a plurality of foot extension structures.
Preferably, said plurality of foot extension ■ structures provided in a removable manner; it can readily assembled or disassembled from the subassembly sections, therefore, facilitates elevation of the subassembly sections from the foundation surface on where it rests.
Once the subassembly sections are well-interlocked, a plurality of joint fastening components detachably secures to the plurality of foot extension structures engaged at the bottom surface of the pallet structure, is provided. This is to strengthen the structural integrity of the pallet structure, especially when it is being moved or . lifted by forklift or semi-truck.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 -shows - an assembled pallet . structure from four subassembly, sections o.f. the present .invention in.. two-by-two arrangement .
Figure 2 shows the plurality of subassembly sections of the present invention.
Figure 3 shows the plurality of foot extension structures and the plurality of joint fastening components embodying the present invention. Figure 4 is a magnified view of interlocking means of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
Further understanding of the object, construction, characteristics and functions of the invention, a detailed description with reference to the embodiments is given in the following
In Figure 1, a pallet structure (100) formed by interlocking four subassembly sections (10a, 10b, 10c, and lOd) is illustrated. Each subassembly section (10a, 10b, 10c, lOd) as illustrated.—..-in... Figure 2. includes a substantially square platform having... an..upper .surface . for load supporting and a bottom surface having a plurality of hollow blocks (15a, 15b, 15c, 15d) provided at each outermost corner for receiving a plurality of corresponding- foot extension structures (20), as shown in Figure 3.
The plurality of foot extension structures (20) detachably engaged to the plurality of hollow blocks (15a,.15b, 15.c, 15d) provided at the lower surface of the section (10a, 10b, 10c, 10d)'. In other words, the plurality of foot extension structures (20) can be readily attached or detached from the subassembly section (10a, 10b, 10c, lOd) whereby the sections (10a, 10b, 10c, lOd) can be raised from the ground on where it rests. Distance between the bottom surface of the section (10a, 10b, 10c, lOd) and the ground can vary, depending on the height of the plurality of foot extension · structures (20) .
In a preferred embodiment, each subassembly structure (10a, 10b, 10c, lOd) has an interlocking means (25a, 25b) provided along its periphery in a manner such that it allows adjacent subassembly sections (10a, 10b, 10c, lOd) of the same to be interconnected therewith, thus forming an assembled pallet structure (100) with desired configurations and dimensions. As oe readily -seen in Figure 4, where . a magnified- view of interlocking. . means . (20.) of the. present invention has presented, the interlocking means (10) is a dovetailed-j oint and is formed from a plurality of trapezoid blocks projecting from the side surfaces of each subassembly section (10a, 10b, 10c, lOd) .
Said plurality of trapezoids blocks (25) suitably includes a pair of complementary interlocking configurations being the male interlocking connectors (25a) and female interlocking connector (25b) .
