Embodiments of the present disclosure relate generally to load carrying structures, and, more particularly, to pallets formed of modular interlocking components.
Load carrying structures, such as pallets are used in a variety of applications to support items thereon, such as to support coils of wire for use in manufacturing, industrial applications, and/or the like. Pallets are often made from wood and are made to be disposable. However, reusable pallets can be more cost effective and durable. Reusable pallets can be made of composites, plastics, metal, or a combination thereof. Conventional pallet designs, however, are often formed of permanently joined (e.g., welded, glued, etc.) components as part of the manufacturing process. As such, transportation of these conventional pallets is cumbersome and expensive due to the rigid nature of these designs and the increased footprint occupied by these designs. Applicant has identified a number of deficiencies and problems associated with conventional pallet implementations. Through applied effort, ingenuity, and innovation, many of these identified problems have been solved by developing solutions that are included in embodiments of the present disclosure as described in detail herein.
Embodiments of the present disclosure address the above by providing pallet implementations formed of a plurality of interlocking components. Further, embodiments provide load carrying structures that do not require welding or bonding of parts in their construction. An example embodiment provided herein includes a load carrying structure that includes: a plurality of side members removably connected to each other to form a base; a first support member and a second support member, where the first support member and the second support member are each removably connected between a respective pair of the plurality of side members; and a top member, where the top member is removably fastened to each of the plurality of side members.
According to an example embodiment, each of the plurality of side members includes a pair of apertures defined therethrough for receiving forks of at least one of a forklift or a pallet jack. According to certain embodiments, the plurality of side members includes a first side member, a second side member, a third side member, and a fourth side member, where the plurality of side members are removably connected to form a quadrilateral-shaped base. According to some embodiments, each of the plurality of side members are identical.
The plurality of side members of an example embodiment each define a top side and a bottom side, where the plurality of side members are connected to each other using a tab and slot, where a respective tab is received within a respective slot and secured through a relatively downward movement of the tab toward the bottom side of a respective side member. The top member of an example embodiment, when fastened to the plurality of side members, precludes disengagement of the respective tab from the respective slot. The first support member and the second support member are, in some embodiments, removably connected to each other. According to some embodiments, the top member, when fastened to each of the plurality of side members, prevents disconnection between the plurality of side members, the first support member, and the second support member. The top member of an example embodiment defines a top surface, where the top surface includes at least one load stabilizing feature. The at least one stabilizing feature of an example embodiment includes a pair of opposing wedges configured to cradle a load therebetween.
Embodiments provided herein include a load carrying structure including: a first side member, a second side member, a third side member, and a fourth side member, where the first side member, the second side member, the third side member, and the fourth side member are connected to form a rectangular base; a first support member removably connected between the first side member and the third side member; a second support member removably connected between the second side member and the fourth side member; and a top member removably connected to the first side member, the second side member, the third side member, and the fourth side member, where the first side member, the second side member, the third side member, the fourth side member, the first support member, and the second support member are precluded from disconnecting from one another in response to the top member being connected to the first side member, the second side member, the third side member, and the fourth side member.
According to some embodiments, the first side member, the second side member, the third side member, and the fourth side member each include a pair of apertures defined therethrough for receiving forks of at least one of a forklift or a pallet jack. According to certain embodiments, the first side member, the second side member, the third side member, and the fourth side member are interchangeable. According to some embodiments, each of the first side member, the second side member, the third side member, the fourth side member, the first support member, and the second support member are formed of sheet metal. According to some embodiments, the first side member, the second side member, the third side member, and the fourth side member are releasably connected by complementary pairs of tabs and slots to form the rectangular base. The top member of some embodiments defines a top surface, where the top surface includes at least one load stabilizing feature. According to some embodiments, the at least one load stabilizing feature includes a pair of opposing wedges configured to cradle a load therebetween.
Embodiments provided herein include a method for constructing a load carrying structure including: interconnecting a first side member, a second side member, a third side member, and a fourth side member to form a rectangular base; connecting a first support member between the first side member and the third side member; connecting a second support member between the second side member and the fourth side member; and connecting a top member to the first side member, the second side member, the third side member, and the fourth side member, where the first side member, the second side member, the third side member, the fourth side member, the first support member, and the second support member are locked together by the top member. According to some embodiments, connecting the top member to the first side member, the second side member, the third side member, and the fourth side member includes fastening the top member to the first side member, the second side member, the third side member, and the fourth side member using a plurality of threaded fasteners. According to some embodiments, interconnecting the first side member, the second side member, the third side member, and the fourth side member to form the rectangular base includes joining tabs and slots of respective side members at each corner of the rectangular base.
Having described certain example embodiments of the present disclosure in general terms above, reference will now be made to the accompanying drawings. The components illustrated in the figures may or may not be present in certain embodiments described herein. Some embodiments may include fewer (or more) components than those shown in the figures.
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all aspects are shown. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the aspects set forth herein. Rather, these aspects are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Pallets, also referred to as skids, as described herein are flat structures used to support goods for transport. Pallets are used in a wide array of industries and provide a relatively common form factor that is adapted for efficient transport. Pallets are used for transporting goods locally around a business location (e.g., within a manufacturing plant) and between locations, such as being carried by truck, shipping container, or the like. Pallets are adapted for transport using forked transport means, such as pallet jacks, forklifts, or the like. These transport means engage pallets through a somewhat standardized interface with the pallets that permit forks of the pallet jacks or forklifts to be received under or through the pallet at a base of the pallet in order to lift and move the pallet and the goods supported thereon.
Pallets are ubiquitous in the transport of goods. The most common material used for pallets is wood as wooden pallets are relatively inexpensive and can be disposable after one or more uses. Wooden pallets are well-suited to the transport of many types of goods. However, wooden pallets often have limited carrying capacities, and can deteriorate over time through exposure to environmental factors along with repeated lift-and-move cycles. Wooden pallets carrying heavy articles are also more prone to degradation. Reusable pallets or pallets designed for longer life are generally made from more robust materials, such as plastics, composites, metal, or combinations thereof. Embodiments described herein can similarly be made from a variety of materials.
An example pallet of the present disclosure may include a plurality of interlocking support structures in the form of interconnected side members configured to form the perimeter of the pallet (e.g., to surround a bounded interior space) which is generally a rectangular, and sometimes a square base to the pallet. These support structures may each, for example, define a plurality of slots on a first end and a plurality of corresponding engagement features (e.g., hooks, flanges, etc.) on a second end opposite the first end. In this way, the plurality of support structures may be configured to be sequentially attached to one another (e.g., via an engagement feature disposed within a corresponding slot) to form the perimeter of the pallet. By way of a non-limiting example, four (4) support structures or side members may be attached via engagement between respective first and second ends to form a rectangular perimeter. In some embodiments, a pair of intersecting support members may be attached to the above-described plurality of support structures so as to provide an interlocking configuration of elements that span the interior defined by the perimeter of support structures.
The interlocking nature of these support members and structures allows for ease of assembly of the example pallet after transportation to the end location. Furthermore, the embodiments described herein may include a top member or support plate that is, following engagement between the interlocking support structures/members, fastened to the network of interlocking support structures so as to provide an exterior surface on which objects may be placed. In a nonlimiting example embodiment described herein, a coil of wire may be supported by a top surface of the top support plate. This configuration may further allow for a forklift or equivalent device to engage the pallet design by placing forks, tines, etc. on a bottom surface (e.g., opposite the top surface) of the top support plate. In this way, the embodiments described herein allow for the modular components of the pallet to be shipped to an end location prior to assembly so as to reduce the burden and cost associated with conventional pallet designs without compromising the structural integrity of the pallet.
In some embodiments, the top member support plate may be further configured to support cylindrical objects thereon in a horizontal position or orientation using load stabilizing features as described herein. By way of example, the top surface of the top member support plate may include one or more contours, groove, ridges, channels, etc. within which a cylindrical coil of wire may be placed in a horizontal position. In other words, the contours, grooves, ridges channels, etc. of the top surface of the top support plate may operate to prevent a cylindrical coil of wire from rolling off of the top support plate. In some embodiments, the features (e.g., contours, ridges, grooves, channels, etc.) configured to prevent this unintended movement of the cylindrical coil of wire may be formed integral to the top support plate (e.g., formed during manufacture of the top support plate). In other embodiments, the features (e.g., contours, ridges, grooves, channels, etc.) configured to prevent this unintended movement of the cylindrical coil of wire may be removably attached to the top surface of the top support plate (e.g., via one or more fasteners, bolts, etc.).
Embodiments of the present disclosure include pallets that are reusable and not subject to the typical wear and degradation of a conventional wooden pallet. Further, embodiments described herein do not require welding or bonding of materials to form a strong, high-capacity pallet. Pallets described herein can be fabricated with fasteners and can include replaceable elements should one or more parts of the pallet be damaged.
According to the illustrated embodiment of
According to the illustrated embodiment of
As illustrated in
The first side member 120, second side member 130, third side member 125, and fourth side member 135 of the illustrated embodiment each have slots defined therein to receive the first or second support member. As shown, the first side member 120 includes slot 122, while the first support member 150 includes slot 154. The slot 122 of the first side member 120 receives an end of the first support member 150 including slot 154. The complementary slots enable full engagement between the first support member 150 and the first side member 120. The third side member 125 similarly includes a slot 127 into which an opposite end of the first support member 150 is received having a complementary slot. The first support member 150 also includes slot 152 proximate a middle of the first support member, while the second support member 160 includes slot 162 proximate a middle of the second support member. These slots are complementary such that the first support member 150 can fully engage the second support member 160 and form a cross-bracing support. In this manner, the first side member 120, second side member 130, third side member 125, and fourth side member 135 along with the first support member 150 and the second support member 160 can be assembled together without any fasteners, welding, or bonding.
Referring back to
Pallets according to embodiments of the present disclosure can be assembled without requiring any welds or bonding of materials. The top member 110 can be affixed to the side members of the pallet through a variety of fastening mechanisms, and can employ welding or bonding in lieu of fasteners if so desired. However, the use of fasteners as described above enables quick assembly of a pallet with only a single tool (e.g., a ratchet and socket or wrench), and permits disassembly and replacement of components with such a single tool. The interlocking tabs and slots join the side members of the pallet together with the support members, and affixing the top member to the side members serves to lock the side members together with one another, as the affixed top member prevents the movement between the sides and support members that would be required to separate them.
The top member 110 can be made from variety of materials, such as metal, composite, reinforced plastic, or the like provided that the top member is sufficiently rigid to not deflect substantially under load. The first side member 120, the second side member 130, the third side member 125, and the fourth side member 135 can similarly be made from a variety of materials; however, the materials should be sufficiently rigid to support a predetermined load based on an intended use of the pallet. The first support member 150 and second support member 160 can similarly be of a variety of materials provided they are sufficiently rigid. In an example embodiment, the top member 110, the side members, and the support members are formed of metal, such as steel, which may be between 1/16- and ΒΌ-inches in thickness or between about 16- and 3-gauge steel. In such an embodiment, the load capacity for a pallet of the present design can be very high, such that loads can be supported beyond the capacity of most other pallet designs and materials. The different components can employ different materials and different thicknesses based on the anticipated load that the pallet will carry.
The interchangeable nature of the components of pallets as described herein provides additional benefits in the form of customizable components that can be used to adapt the pallet to specific use cases. According to an example embodiment, the top member of a pallet can be replaceable with top members having different form factors and adapted to better handle specific types of loads.
While the embodiment of
Other embodiments of attachment features may be employed based upon a load to be carried by the pallet. The attachment features may include pairs of slots, where tie-down straps can be fed through the pairs of slots and secured over a load carried on the pallet. Other attachment features may include slots formed for engagement by tie-down hooks, such as radially extending slots that can receive therein a tie-down hook that, when secured, is turned 90-degrees relative to the slot to be secured within the slot and tensioned to secure the load. Other attachment features may include threaded inserts, such as rivet nuts, that may be received within the top member 410 and used to receive fasteners therein. The attachment features can be sized and positioned on the top member to accommodate a specific load form factor. Optionally, the attachment features can be distributed on the top member suitable for securing a variety of loads with a variety of types of fasteners and/or straps.
A variety of load stabilizing features may be implemented together with a variety of attachment features to secure the load stabilizing features to the top member of the pallet. These load stabilizing features and attachment features can be made specifically for a particular use case, such as used for the coil of metal wire as illustrated in
