[0002] PORTABLE SHEET STACKER STORAGE SYSTEM AND PROCESS
[0003] CROSS-REFERENCE TO RELATED APPLICATIONS
[0004]
[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 688,726, filed August 29, 2024, and titled: PORTABLE SHEET STACKER STORAGE SYSTEM.
[0005] TECHNICAL FIELD
[0006]
[0002] The present disclosure generally relates to portable storage systems for materials, and more particularly relates to a portable sheet stacker storage system and process with adjustable securing mechanisms and removable components for efficient handling and transportation and enhanced safety profile, preferably of flat sheets of material.
[0007] BACKGROUND
[0008]
[0003] Material storage and transportation have historically been challenging operations in various industries due to the physical demands placed on workers, the risk of material damage, and the limitations of existing equipment. These processes often involve handling heavy and bulky materials such as ground protection mats, sheets of plywood, and sheetrock. Ensuring the safe and efficient movement and storage of such materials is essential to maintaining productivity and minimizing workplace hazards. However, the reliance on manual labor and the use of generic storage equipment have presented significant challenges over time.
[0009]
[0004] One of the persistent issues in this area is the occurrence of workplace injuries during material handling. Workers are often required to lift, shift, or stack heavy materials manually, which can lead to musculoskeletal injuries, accidents, or other safety incidents. The physical strain associated with these tasks has been a longstanding concern, as it increases the likelihood of injuries and reduces worker productivity. Additionally, the lack of specialized tools or equipment designed to handle CASE NO.: THU-3080677-PCT materials of varying sizes and weights has further complicated these processes, leading to inefficiencies and operational delays.
[0010]
[0005] Another challenge is the inefficiency in the storage and transportation of materials. The absence of standardized methods or equipment has resulted in wasted time, increased labor costs, and difficulties in organizing and securing materials during transit. This inefficiency not only affects productivity but also increases the risk of material damage, which can lead to additional costs and delays. Furthermore, the durability and usability of existing equipment have often been inadequate, with many solutions either lacking the necessary robustness to handle heavy loads or being cumbersome to operate.
[0011]
[0006] Historically, industries have relied on manual labor and generic storage solutions to address these challenges. However, these methods have proven to be insufficient in meeting the demands of modern operations, where safety, efficiency, and reliability are critical. The limitations of these traditional approaches have underscored the need for improved methods to manage material storage and transportation effectively.
[0012]
[0007] By focusing on these historical and industry-wide challenges, it becomes evident that the current practices in material storage and transportation are inadequate in addressing the risks and inefficiencies associated with manual handling, improper storage, and the lack of specialized equipment. These challenges highlight the need for advancements in this area to ensure safer and more efficient operations.
[0013] SUMMARY

Each corner post is repeatably selectively securable to and removable from the corner. The process also includes providing at least one pin down bar located along a side of the base and connected with the base and extending vertically upward from the base between a location of two of the corner posts. The pin down bar is removably rotatably connectable to the base via a rod slot and configured to be rotatable relative to the rod slot while remaining seated in the rod slot. Another step of the process is providing an angle nut joined with the pin down bar and being selectively adjustable relative to a vertical length of the pin down bar. The angle nut is configured to secure in place the flat sheet relative to the base. Another step is providing a pair of fork-lift pockets. Each pocket is spaced apart from the other and each pocket is located in the base along a length of the base or a width of the base. Yet another step is locating the corner post and the pin down bar within at least one of the pair of fork-lift pockets. And, still another steps is securing closed at least one of the pair of fork-lift pockets with at least two angle nuts, and one angle nut is securely located at opposite ends of each of the pair of fork-lift pockets.
[0016]
[0010] Still other aspects of the disclosure are directed to configurations and features for: stackable and mounting targets and their respective bullets, pin down bar and its pieces and parts including the angle nut, the pairs of fork-lift pockets, and, the grapple bar and its grab bar. CASE NO.: THU-3080677-PCT

[0043] DETAILED DESCRIPTION
[0044]
[0035] The present disclosure relates to modular and stackable storage and transportation systems, and related processes, designed for secure handling of goods in industrial and commercial environments. In various implementations, systems may include multiple components that interact to provide stability, safety, and compliance with recognized industry standards.
[0045]
[0036] In FIGS. 1 to 4 and 16, for example, portable sheet stacker storage system 10 includes base 30, which serves as the primary support structure and can have corners 32, and preferably four such corners, providing mounting locations for each corner post 40. Corner post(s) 40 can be removably attached to base 30, preferably at four corners 32, respectively, extending vertically upward from the base and providing vertical structural support and rigidity. Corner post holes 41 in corner posts 40 may be used for further securing down sheet material like flat sheets 12 or for receiving fasteners to further stabilize the structure. Vertical channel 42 is formed along the inner length of corner posts 40, allowing guided insertion or alignment of corners 14 of flat sheets 12 in their various configurations (FIGs. 12-15 for example). Stackable bullet 44 is positioned at distal end 46 of corner posts 40, functioning as an alignment and stacking feature to enable multiple units to be securely stacked atop one another. Stackable bullet 44 engages with corresponding stackable target 34 on adjacent units to ensure stability and prevent longitudinal and lateral movement during stacking or transportation.
[0046]
[0037] Sides 52 of base 30 provide boundaries for the storage area and serve as mounting locations for additional components. Pin down bars 60 can be inserted through rod slots 64, which are formed in base 30 along sides 52, to secure loads placed within system 10. Pin down bars 60 help prevent movement of stored sheets or materials during handling and transport, along with corner posts that each having a vertical inner channel. Pin down bar(s) 60 help secure(s) the load of sheets 12 within the CASE NO.: THU-3080677-PCT system, and can be inserted through designated handholds or slots 16 and working with other securing mechanisms such as angle iron 86, which can be L-shaped 88, for example being a 90° angle clip. D-ring 26 is attached to base 30 at sides 52 and serves as an attachment point for securing straps, chains, or other tie-down mechanisms, as well as for pickup of the system by a crane or the like, enhancing safety and security of the load during transportation. These can be used to secure materials to base 30 and / or secure base 30 to another fixed surface 24, as described further below.
[0047]
[0038] Angle nut 80 is configured to secure in place the flat sheets 12 relative to base 30. At a minimum, angle nut 80 includes nut 84 and angle iron 86, or similar functioning parts, which together fasten or clamp flat sheet 12 together on the base, with angle iron 86 providing additional structural reinforcement at critical junctions such as the top edge 22 of a stack of sheets 12 along sides 20 located within corner posts 40. Angle nut handle 89 is attached to nut 84, allowing manual tightening or loosening of the connection for assembly and disassembly of angle nut 80.
[0048]
[0039] Pairs of fork-lift pockets 90 are integrated into base 30, allowing engagement by forklift tines from either side or all sides for efficient lifting, maneuvering, and placement in various environments. Length 54 refers to the longitudinal dimension of the system, relevant for determining capacity, compatibility with transportation equipment, and compliance with industry standards. Width 56 defines the lateral dimension, ensuring compatibility with standard equipment and efficient handling by forklifts or other machinery, as well as compliance with industry standards. The pairs of fork-lift pockets 90 are integrated into opposing sides, providing access points for forklift tines and enabling lifting, movement, and positioning from any side, as well as storage of pieces and parts of the system 10 as described further herein.
[0049]
[0040] In FIGS. 2 to 4, D-rings 26 can be positioned at a corner region to provide an attachment point for securing straps or tie-down mechanisms, used during transportation or storage to enhance safety by allowing operators to fasten the system to a vehicle, trailer, or other support structure, or lift the system 10 (e.g., with a crane). Stackable bullet 44 is located at a top surface and functions as an alignment and CASE NO.: THU-3080677-PCT stacking feature, engaging with a corresponding stackable target on an adjacent system 10 for secure stacking and precise alignment. Rod slot 64 is formed along a structural member of the base 30 and serves as a receptacle for pin down bars 60, allowing insertion of a bar 60 for additional security and stability to secure a load of sheets material 12. Angle iron 86 is positioned along an edge of the sheets 12, providing fitted security and stability for the load. Angle nut handle 89 is attached to nut 84, and together they form angle nut 80, functioning as a manual adjustment or securing mechanism for tightening or releasing sheets of material 12 as the angle nut is selectively adjustable relative to the vertical length 62.
[0050]
[0041] In FIG. 5, a perspective end view of an alternate version, introduces grapple bar 100. Base 30 provides foundational support. Proximate end 48 refers to the end of corner posts 40 closest to the base 30, facilitating access to key components. Post adjusting pin 49 is located adjacent to proximate end 48 for adjusting or further securing in place removable corner posts 40. For example, this can be a nut or threaded relationship with the post housing slot, in which a bolt is secured to screw in and out to engage the proximate end of the corner post seated in the housing slot (as in FIGs. 1-4 for example). Off-set location 58 indicates a specific position on base 30 for mounting grapple bar components to optimize load distribution and accessibility. Grapple bar 100 facilitates secure lifting and handling, with pair of legs 102 extending downward for stable support and alignment with base 30. Lower end 104 connects with base 30, anchoring grapple bar 100. Upper end 106 connects to grab bar 108, forming a rigid structure for lifting operations. Grab bar 108 serves as the primary engagement point for lifting equipment, with single point of contact 110 allowing precise and secure attachment thereto. Angled upper edges 112 at upper end 106 further facilitate single point of contact engagement with lifting hooks, and vertex angle 116 is at the intersection of angled upper edges 112 for enhanced strength and durability during lifting. Vertex 116 can have an angle in the range of 45 degrees to 15 degrees, preferably 35 degrees to 20 degrees, more preferably 25 degrees to 20 degrees and most preferably about 22.5 degrees. Integration of grapple bar 100, pair of legs 102, and CASE NO.: THU-3080677-PCT associated features enables efficient and safe lifting and transportation. D-ring 26, post adjusting pin 49, and off-set location 58 contribute to securement and adjustability.
[0051]
[0042] In FIG. 6, corner post 40 is a removable structural member, secured to base 30 for stability during stacking, storage, and transportation. Corner posts 40 are each removable for flexible configuration and compact storage. Corner post 40 interacts with stackable target 34 for secure stacking and serves as an attachment point, via holes 41, for ratchet connections, D rings, or other securing mechanisms, when desired. Vertical channel 42 is an elongated recess or guide formed in each corner post along its inner length, designed to receive and retain corners 14 of sheets 12 in a fixed position, further facilitating secure engagement and preventing lateral and longitudinal movement of sheets 12. Vertical channel 42 also assists with easy and more stable load bearing, removal and installation of corner post 40, supporting modularity and reconfigurability.
[0052]
[0043] In FIG. 7, post securing pin 47 secures removable corner post to the base 30. Post securing pin 47 is inserted through hole 48a in the post and then into and through hole 48b in the corner housing slot of the base, and aligned during assembly to secure the removable corner post in place. This provides structural support and rigidity, enabling attachment or detachment for flexible configuration. Post securing pin 47 facilitates quick assembly and disassembly, supporting efficient operation during loading, unloading, stacking, or transport.
[0053]
[0044] In FIG. 8, stackable target 34 is viewed from the bottom, showing features for secure stacking and alignment. Stackable target 34 interacts with stackable bullets 44 for precise positioning and stability. Cotter pin 48c secures post pin 47 in place to prevent withdrawal or loosening, when pin 47 is inserted through holes 48a, 48b and another hole on an opposite side of stackable target 34 not readily visible. In this way, the bent post pin 47 enters the configuration of post holes from one side and passes out the other side where the cotter pin 48c is inserted to prevent post pin 47 from withdrawing back through its set of holes, until disassembly of the corner post 40 from the base 30 is desired. This arrangement secures structural elements, supporting CASE NO.: THU-3080677-PCT modularity and stackability, and facilitates efficient assembly, disassembly, and reconfiguration.
[0054]
[0045] In FIGs. 9 and 10, fixed surface 24 provides a stable support for securing the system 10. Mounting bullet 38 is attached to fixed surface 24, serving as an anchoring component for securement of system 10, and other elements if desired. Mounting bullet 38 interacts with mounting targets 36 or other features for attachment to fixed surface 24, such as a trailer. Locking pin and ring 39 secures mounting bullet 38, inserted through aligned aperture 37 in target 36 for a positive locking mechanism. This ensures mounting bullet 38 remains fixed during movement or handling, contributing to stability and safety. Mounting bullet 38, when secured and locked, serves as a critical interface for connecting the unit to transportation equipment, allowing efficient loading, unloading, and securement. In FIG. 10, mounting target 36 and base 30 are disconnected from mounting bullet 38, showing an unsecured mode. Fixed surface 24 provides a stable foundation for both secured and unsecured configurations. In the unsecured mode, mounting target 36 is separated from mounting bullet 38, allowing disassembly, repositioning, or reconfiguration.
[0055]
[0046] In FIG. 11, pin down bar 60 includes vertical length 62, extending between distal end 76 and proximate end 77. Vertical length 62 spans the required distance for securing loads. Threads 66 can be formed along all or a portion of vertical length 62 for engagement with nut 84, for example threaded nut 82, which adjusts and secures the position of angle iron 86. Nut 84 and angle iron 86 can be (i) fixedly attached together or (ii) separated and only operating adjacent each other and not fixed together. A plurality of widthwise through-holes 68 can be distributed along vertical length 62, providing extra selectable stop locations for a locking pin and ring, not shown but can be like that seen as 78 or comparable structures as would be known to one of ordinary skill in the art combined with the teachings herein. Locking pin and ring 78 can be inserted through a lower-most of the widthwise through-holes, like holes 68, fixing pin down bar 60 within any of rod slot 64, and yet still rotatably connected to the base by remaining seated in the rod slot and unable to come back out as long as the locking pin and ring 78 CASE NO.: THU-3080677-PCT are in place. For example, locking pin and ring 78 can be as seen in FIGs. 3 and 4, where washer 79 abuts against rod slot 64 from underneath an upper layer of base 30 to prevent pin down bar 60 passing back through the rod slot when the locking pin and ring 78 with washer 79 thereabove are attached to the pin down bar, and the pin down par is removably rotatably connected with the base via rod slot 64.
[0056]
[0047] Still referring to FIG. 11, collar 74 is disposed at distal end 76 of the pin down bar, serving as a final reference or abutment point, beyond which the angle nut 80 cannot pass off of the bar 60. Angle iron 86 can have an L-shaped 88 profile for a more engaging mounting surface with the side edge 20 and even top edge 22, of sheets 12.
[0057] Pin down bar 60, with angle iron 86, nut 84 (and preferably threaded nut 82), locking pin and ring 78, washer 79, and collar 74, stabilizes and secures loads, preventing movement and ensuring compliance with safety standards. The plurality of widthwise through-holes 68 and stop locations allow additional adjustable positioning and fastening redundancy, and angle nut handle 89 facilitates rapid and secure adjustment.
[0058] It should also be understood that bar 60 can be connected to the base within rod slots 64 and (i) fixed relative to slots 64 where the nut and angle nut handle then rotate around the bar 60 to go up and down the vertical length 62 of the bar 60 and / or (ii) preferably, rotatable relative to slot 64 where the nut 84 and angle nut handle 89 then can remain stationary relative to the length 54 and the bar 60 is rotated to move the nut and angle nut handle up and down the vertical length 62 of bar 60. Additionally, if desired, both the bar 60 and the nut and angle nut handle can rotate relative to each other to give maximum flexibility for securing a load of sheet material to the base.
[0059]
[0048] In FIGS. 12 to 15, flat sheet 12 is a sheet of material intended to be carried by system 10. Flat sheet 12 serves as a load or item to be stored and transported, positioned for secure handling and movement. Hand-hold 16 is formed in flat sheet 12, providing access for manual or mechanical engagement, allowing operators to grip, lift, or maneuver flat sheet 12. Hand-hold(s) 16 (if provided) also serves as a passage for pin down bars 60, inserted to provide additional stability and security to the base 30.
[0060] Corners 14 of sheets 12 represents a defined edge or intersection, relevant for CASE NO.: THU-3080677-PCT alignment or engagement with corner post vertical channels 42. Sheet sides 18 and side edges 20 define the perimeter, positioned adjacent to other sheets or components during stacking. Top edges 22 denote the uppermost boundary, relevant for positioning and access during loading and unloading, and relevant for alignment or engagement.
[0061]
[0049] Flat sheet 12 is loaded by aligning side edges 20 with corner posts and angle irons, using hand-holds 16 (if provided) to insert pin down bars 60 for securement to base 30. Sides 18 and side edges 20 interact with adjacent sheets or components to maintain a uniform stack and facilitate handling by forklifts or cranes. Top edge 22 provides a reference for stacking orientation and access. In alternate versions, flat sheet 12 is positioned within the system, interacting with stackable bullets, stackable targets, removable corner posts, and securing mechanisms. Flat sheet 12 is stabilized by removable corner posts and further secured using angle nuts joined with pin down bars. Flat sheets 12 are accessed and maneuvered using fork truck pockets on all four sides, facilitating versatile handling and transportation. During operation, flat sheets 12 remain stationary and protected, benefiting from compliance features and safety measures. Flat sheets 12 may be removed or replaced as needed, supporting modularity and flexibility.
[0062]
[0050] In other aspects, and referring to FIGs. 1 and 5 for discussion here, there is disclosed a process for the portable sheet stacker storage system 10 for flat sheets 12. The process includes providing base 30 including corners 32 and at least two corners 32 each including corner post 40 extending vertically upwardly from the base. Each corner post is including vertical channel 42 configured to receive and locate corners 14 of flat sheet 12 in the vertical channel. Each corner post is repeatably selectively securable to and removable from the corner (e.g. as also shown and discussed in reference to FIGs. 6-8). The process also includes providing at least one pin down bar 60 located along a side 52 of the base and connected with the base and extending vertically upward from the base between a location of two of the corner posts 40. The pin down bar is removably rotatably connectable to the base via rod slot 64 and configured to be rotatable relative to the rod slot while remaining seated in the rod slot (e.g. as also CASE NO.: THU-3080677-PCT shown and discussed in reference to FIGs. 2-4 and 11). Another step of the process is providing angle nut 80 joined with the pin down bar and being selectively adjustable relative to vertical length 62 of the pin down bar (e.g. as also shown and discussed in reference to FIGs. 2-4 and 11). The angle nut is configured to secure in place the flat sheet relative to the base. Another step is providing at least one pair of fork-lift pockets 90. Each pocket is spaced apart from the other and each pocket is located in the base along length 54 of the base or width 56 of the base.
