Description

[Technical field]

[0001]

[0001] This application claims priority to U.S. Provisional Patent Application No. 62 / 842 / 899, filed May 3, 2019, the disclosure of which is incorporated herein by reference in its entirety.

[0002]

[0002] The present invention relates to a system that may be incorporated as part of an associated delivery vehicle or as an add-on to an existing associated delivery vehicle. The system has an automated lift assembly and defines a process for unloading cargo from an associated delivery vehicle. However, it should be recognized that the system and process may also be used to transport cargo and / or load cargo into a vehicle. [Background technology]

[0003]

[0003] Delivery vehicles are well known in the art. For example, panel vans, cargo trucks, and trailer truck trailers are all used to deliver cargo from one location to another. As mentioned above, the present invention may be included as part of a conventional delivery vehicle or may be provided as an add-on equipment option to convert the delivery vehicle into an automatic / autonomous lift assembly. The vehicle itself may be an autonomous vehicle or may be a vehicle that requires a driver.

[0004]

[0004] There is a rapid increase in the demand for delivery vehicles in connection with the delivery of goods (generally referred to herein as cargo or cargo items, but which may relate to a variety of items, containers, packages, boxes, etc.). Over time, it is expected that more of these vehicles will become autonomous or semi-autonomous (reducing the human labor and human interaction required to load, unload, and transport the cargo) and provide driverless delivery vehicles that receive cargo from a first location (e.g., a factory, warehouse, post office, etc.) and transport the cargo to a second location (e.g., a post office, delivery hub, or intermediate warehouse, business, residence, etc.). It is further expected that delivery vehicles will carry a variety of cargoes, i.e., not all of the cargoes may be the same items, or even equal types of items, equal sizes, equal weights, etc. Thus, it is expected that the cargo compartment of the delivery vehicle will be one compartment with multiple compartment portions.

[0005]

[0005] The cargo compartment preferably has a door that selectively allows access to the compartment, thereby allowing additional cargo to be added to one or more of the compartment parts or removing cargo previously placed in the compartment part. When cargo is added to or removed from the compartment part during the designated route, it may further be necessary to redirect the cargo within a different compartment part. For example, cargo originally stored in one compartment part may be relocated during the delivery route when some cargo becomes difficult to access and it becomes necessary to relocate the received cargo or the relocated cargo during the route to complete the delivery at the desired location.

[0006]

[0006] Therefore, there is a need for improved systems, processes, and configurations that provide at least one or more of the above-mentioned features to overcome one or more of the above-mentioned deficiencies, as well as provide other features and advantages. Summary of the Invention [Means for solving the problem]

[0007]

[0007] An autonomous cargo loading or unloading system for an associated delivery vehicle is provided.

[0008] The system preferably includes an associated vehicle storage compartment that stores associated cargo in at least one compartment portion, where the cargo is received from or delivered through an opening leading to the storage compartment. A conveyor is located in each compartment portion and configured to assist in delivering the associated cargo from the compartment portion or receiving the associated cargo into the associated compartment portion. A lift assembly is movably mounted to the storage compartment and configured to receive the associated cargo from the compartment portion. The lift assembly has a lift assembly conveyor that receives the associated cargo from the compartment portion or delivers the associated cargo to the compartment portion.

[0008]

[0009] The storage compartment may be divided into multiple compartment portions, such as an array of at least two high by two wide (2×2) compartment portions.

[0010] A lift assembly has a platform for receiving an associated cargo from or delivering an associated cargo to one of the compartment portions.

[0009]

[0011] A preferred mounting assembly movably secures the lift assembly to the storage compartment, the mounting assembly having first and second vertical guide members disposed at horizontally spaced locations in the storage compartment. The first and second horizontal guide members are provided at vertically spaced locations, each horizontal guide member having first and second ends interconnected to the vertical guide members and vertically movable relative to the vertical guide members. A platform is preferably secured to the first and second horizontal guide members and movable along the first and second horizontal members between the first and second vertical guide members so that the platform can be positioned in a selected compartment portion of the array.

[0010]

[0012] The platform of the first embodiment has a first edge pivotally mounted to a second horizontal guide member such that the platform is movable between a first vertical position, i.e., a first storage position, and a second horizontal position, i.e., a second deployment position.

[0011]

[0013] At least one linkage assembly has first and second links, a first end of the first link fixed to the first horizontal guide member, a first end of the second link fixed to a second edge of the platform, and second ends of the first and second links hingedly connected to each other.

[0012]

[0014] Desirably, the platform is movably mounted on the first and second horizontal members such that the platform can move laterally relative to the compartment portion.

[0013]

[0015] Additionally, desirably, the platform is movably mounted to the first and second vertical members such that the platform can move vertically relative to the compartment portion.

[0014]

[0016] The mounting assembly is dimensioned to allow the platform to move to a horizontal location below the compartment portion.

[0017] A platform in one configuration has a lift assembly conveyor operatively associated with the platform.

[0015]

[0018] In a preferred configuration, the lift assembly conveyor has first and second conveyor portions separated by a gap and at least one push bar extending through the gap, the at least one push bar configured to engage associated cargo received on the platform and to facilitate movement of a first associated cargo component relative to an adjacent second associated cargo component.

[0016]

[0019] A push bar is mounted for movement with the first and second conveyor sections.

[0020] In one embodiment, the push bar is mounted on the platform in a weighted manner, where the push bar extends through the gap and extends above the surfaces of the first and second conveyor sections when the push bar traverses the lift platform from the first edge to the second edge, and where the push bar is below the surfaces when the push bar traverses the lift platform from the second edge to the first edge.

[0017]

[0021] Sensors may be provided for monitoring the movement of associated cargo from the compartment section conveyors to the lift assembly conveyors.

[0022] One configuration of the system has a first motor operably associated with the conveyor of at least one of the compartment portions, a second motor operably associated with the lift assembly conveyor, and a controller in communication with the lift assembly, the placement assembly, the sensor, the first motor, and the second motor for deploying and storing the platform, moving the platform between and beneath the compartment portions, monitoring the position of the first associated cargo component, and responsively controlling the relative speeds of the compartment portion conveyor and the lift assembly conveyor to convey the first associated cargo component onto the lift assembly conveyor.

[0018]

[0023] Processes for loading or unloading the associated cargo onto or from the associated delivery vehicle are further provided.

[0019]

[0024] A delivery vehicle has a storage compartment system having compartment portions dimensioned to receive cargo therein, a first motor operably associated with a conveyor of at least one of the compartment portions, a lift assembly having a platform with a lift assembly conveyor, the lift assembly being secured to the storage compartment system via a mounting assembly, a sensor, a second motor operably associated with the lift assembly conveyor, and a controller. The controller communicates with the lift assembly, the mounting assembly, the sensor, the first motor operably associated with the compartment portions, and the second motor operably associated with the lift assembly conveyor, and the second motor for deploying and storing the platform, moving the platform between the compartment portions, and transporting associated cargo from the compartment portions to the platform and / or to the ground.

[0020]

[0025] The conveying step includes moving the associated cargo from the compartment portion to a ground (eg, the ground) at a location below the compartment portion.

[0026] The process may include sensing a position of the associated cargo during the conveying step, and operating a compartment portion conveyor and a lift assembly conveyor to separate the associated first and second cargo items.

[0021]

[0027] The moving step may include raising and lowering the platform between the vertically offset compartment portions and / or moving the platform laterally between the horizontally offset compartment portions.

[0022]

[0028] The process further includes moving the platform between the storage location and the deployed location.

[0029] The step of moving the platform includes pivoting the platform between a vertical orientation defining a storage position and a horizontal orientation defining a deployed position.

[0023]

[0030] The storage compartment system further includes a door, and the process further includes opening and closing the door to selectively access the storage compartment.

[0024]

[0031] An alternative storage compartment system may have a pair of support rails with rollers that allow cargo to be pivoted into or out of a cargo compartment or compartment portion rather than using a conveyor.

[0025]

[0032] The fence may be associated with a flexible drive member (eg, a chain, cable, or belt) that pushes cargo into or out of the compartment or compartment portion.

[0026]

[0033] The first and second motors driving the first and second fences may be monitored and advantageously used to press or apply a longitudinal compressive force to adjacently disposed cargo items received between the first and second fences.

[0027]

[0034] Additionally, the rear (e.g., second) fence can be automatically moved from a vertical cargo push position to a horizontal bridge position where the fence acts as an extension to pass or carry cargo from the rollers of the storage compartment system to the platform.

[0028]

[0035] Optional use of the rear fence as a bridge allows the gap between the lift assembly and the storage compartment system to receive a movable door which allows selective access to the compartments.

[0029]

[0036] A first advantage of the present disclosure is the ability to provide a lift assembly having a platform that moves vertically up and down, and laterally from side to side relative to a storage compartment.

[0030]

[0037] Another benefit resides in the use of integrated conveyors associated with the compartment portions and associated with a lift platform for moving cargo to / from the delivery vehicle.

[0031]

[0038] Another advantage is associated with the control device providing autonomous operation of loading and unloading cargo onto and from the delivery vehicle to relocate cargo into separate compartment portions of the delivery vehicle, and positioning the cargo at different locations along the ground as needed.

[0032]

[0039] Software monitors the current draw associated with the first and second motors that drive the first and second fences, respectively, to determine when a pushing or compressive force is applied to a cargo item between the fences.

[0033]

[0040] Pushing or compressive forces on the cargo may be utilized to ideally position the cargo within the compartment and / or stabilize the cargo during acceleration or deceleration of the vehicle during vehicle operation.

[0034]

[0041] Other benefits and advantages of the present disclosure will become more apparent upon reading and understanding the following detailed description. [Brief description of the drawings]

[0043]

[0054] FIG. 1 illustrates the rear or back end of a wheeled delivery vehicle 100, such as a cargo van, box truck, trailer, or storage container pod that may be selectively installed or removed from the vehicle, having a door 102 that allows access to an interior cargo compartment 104. In the illustrated embodiment, the door 102 is an overhead door, such as a garage-type door having a series of panels each supported along opposing edges by rollers received in a generally C-shaped track. Specific details of the door are not shown, as the structure and operation of such overhead doors are well known and understood by those skilled in the art, and thus no further explanation is necessary to fully and completely appreciate the present disclosure. Moreover, the description of this type of door 102 is not intended to exclude the use of other types of doors, but rather to illustrate the ability to open and close access to the cargo compartment 104 of the vehicle 100.

[0044]

[0055] An automated lift gate or lift assembly 110 is attached (e.g., added or installed) to the rear end of the vehicle 100 or is integrated as part of the original vehicle. The lift assembly 110 is joined to the cargo compartment 104 of the vehicle 100 via a mounting assembly 112. The mounting assembly 112 has a first vertically extending track or channel 114 and a second vertically extending track or channel 116 located along a rear, lateral outer edge of the cargo compartment 104. As shown in the figure, the channels 114, 116 can extend a greater amount of vertical extension than the storage compartment 104, specifically, in this example, the channels extend outwardly from a lower edge of an opening or access portion leading to the cargo compartment 104. Although the channels 114, 116 are shown as stationary components that always extend below the lower level of the cargo compartment, it is also contemplated that the channels may terminate at the base of the cargo compartment and may have extendable / retractable or telescopic portions that allow the channels to extend longer, thereby allowing the channels to collapse or shorten their length when not in use during loading or unloading of cargo. In a preferred configuration, the installation assembly 112 has a generally rectangular frame 120 having a first or upper horizontal member 112 and a vertically spaced apart second or lower horizontal member 124. In addition, the frame 120 has a first vertical member 126 and a second vertical member 128 joined to opposite ends of the first horizontal member 122 and the second horizontal member 124.

[0045]

[0056] In a preferred embodiment, portions of the mounting assembly 112, specifically the channels 114, 116 and the frame 120, support the lift assembly 110 for movement relative to the cargo compartment 104. More specifically, the lift assembly 110 has a platform 140 joined to the frame 120, where the platform is either made as part of the vehicle 100 or is mounted to the vehicle 100 at an open end of the cargo compartment 104. Specifically, the frame 120 and the platform 140 move relative to the cargo compartment 104 in a manner that will be described below. In a preferred version, the platform 140 is preferably pivotally or hingedly mounted along a first edge of the frame 120, specifically to the lower horizontal member 124. Additionally, the frame 120 is movable relative to the cargo compartment 104. Generally, however, the frame 120 is intended to be selectively moved vertically, where the vertical range of movement is at least dimensioned to generally match the height of the door 102, thereby allowing access to the entire cargo compartment 104. In addition, the frame 120 is preferably capable of moving vertically downward, such that the second or lower horizontal member 128 of the frame and the platform 140 pivotally attached thereto are positioned adjacent the ground, for example, below the rear end of the vehicle 100.

[0046]

[0057] As described above, the platform 140 is mounted to the frame, and specifically, for example, the second horizontal member 124, so that the platform can pivot between an upright vertical storage position (FIGS. 1, 16, and 17) and a horizontal operating position (FIGS. 2-14). A first arm 142 and a second arm 144 (FIGS. 2-3) extend between a second edge of the platform 112 and the first or upper horizontal member 122. In the embodiment shown, each arm 142, 144 is a two-bar linkage in which a first link arm portion 142a (142b) is rotatably joined to a second link arm portion 144a (144b) via a pin connection 146 that allows selective rotational or pivotal movement about a pin between the first and second link arm portions. Each first link arm portion 142a, 142b is rotatably joined at a first end to the first or upper horizontal member 122 of the frame 120. Each second link arm portion 144a, 144b has a first end that is rotatably joined to a respective first link arm portion 142a, 142b via a pin 146a, 146b, respectively. Additionally, a second end of each second link arm portion 144a, 144b is rotatably joined to the platform 140, and specifically, to a side frame 150 of the platform 140.

[0047]

[0058] In the storage position (i.e., when the platform 140 is in an upright, vertical storage position), the first link arm portion 142a, 144a and the second link arm portion 142b, 144b overlap one another (FIG. 1). On the other hand, in the deployment position (i.e., when the platform 140 is in a horizontal operating position) (FIG. 3), the first link arm portion 142a and the second link arm portion 144a are generally longitudinally aligned. FIG. 2 illustrates the transition positions of the link arm portions 142a, 144a between the storage and deployment positions. A motor (e.g., an electric motor, a hydraulic motor, a pneumatic motor, etc.) selectively moves the platform 140 between the storage and deployment positions.

[0048]

[0059] In a preferred configuration, the platform 140 is stored in an upright vertical position as shown in FIG. 1, although one skilled in the art would recognize that alternative storage locations and platform positions may be used without departing from the scope and intent of the present disclosure. Removal of the link arms 142, 144, and possibly the upper horizontal member 122 of the frame 120, eliminates the ability of the link arms to block lateral movement of cargo, but allows for storage of the platform 140 in a horizontal position below the storage compartment, for example. In such an alternative configuration, the platform 140 may be moved to a horizontal storage position above or below the cargo compartment. Similarly, modifications may be made to accommodate storage of the platform 140 along the side of the cargo compartment 104 or even within the cargo compartment, although none of these alternatives are believed to be as desirable as the one shown in the accompanying drawings. This is because the lift assembly of the present disclosure can be offered as an add-on option to existing vehicles and further because the lift assembly 100 can be easily integrated into OEM vehicle builds.

[0049]

[0060] Another motor moves the frame 120 vertically up and down relative to the channels 114, 116, thereby selectively repositioning the platform 140 to different vertical locations relative to the cargo compartment 104 (see the three different heights of the platform in Figures 2-4). Additionally, the range of movement of the frame 120 in the vertical direction extends to a lower position shown below the cargo compartment 104, for example as shown in Figure 12, so that cargo items can be transported from the platform 140 to an associated surface, such as the ground.

[0050]

[0061] Another motor moves the platform 140 laterally relative to the frame 120, so that the platform can be repositioned left and right relative to the storage compartment 104. For example, a comparison of Figures 2-4 illustrates the lateral movement of the platform 140. It should be appreciated that the vertical movement of the frame 120 (and thus the vertical movement of the platform 140) may be independent of or combined with the lateral movement of the platform to maximize the speed and efficiency of operation of the platform 140.

[0051]

[0062] 2-15, the cargo compartment 104 may be one large compartment or may be subdivided into separate compartment portions. For example, where no physical division or separation of the cargo compartment 104 is performed, large or small cargo items may be received within a single cargo compartment. In other examples, the cargo compartment 104 may be divided to have (i) physically separated compartment portions (i.e., compartment portions having physical barriers), (ii) compartment portions that do not have physical barriers separating the areas of the compartment portions from the smaller portions but operate as separated compartment portions, or (iii) a combination of physically separated or non-physically separated areas of the compartment portions. Additionally, it should be appreciated that the compartment portions may or may not be of equal size. For example, as shown in FIG. 2, the cargo compartment 104 has three separate heights 104A, 104B, 104C. A first or upper level 104A forms a compartment portion defined in part by the cargo compartment 104 and the upper wall or ceiling of the cargo compartment. There is no physical barrier laterally subdividing or separating the upper level 104A, but the upper level is "shown" as three separate compartment portions evidenced by three separate laterally extending cargo items extending across the upper level. The "floor" of the upper level 104A is formed by three separate conveyors 160, shown here as equal sized conveyors (although it is recognized that the conveyors may be of different sizes). Each conveyor 160 within one compartment portion, and associated with the movable platform 140, is of conventional configuration having at least first and second conveyor rollers 162 (FIGS. 19-20) spaced longitudinally (and likely having multiple intermediate conveyor rollers) and surrounded by a belt 164 extending as a continuous loop, rotating about the conveyor rollers.While the conveyor 160 is of conventional construction, the belt 164 has been removed from one of the conveyor sections in FIGS. 19-20 for ease of illustration and to more particularly show the rollers 162 disposed in spaced apart relationship. The rollers 162 of adjacent conveyors 160 on the platform 140 are preferably interconnected to cause the respective belts 164 to move at equal speeds. Typically, one or more of the conveyor rollers 162 are powered or motorized such that the belt 164 rotates to define a movable upper belt surface 164 that advances around a first endmost roller and further defines a movable lower belt surface 164B that advances around a second endmost roller. Thus, a cargo item C is placed on and moved by the upper belt surface of the conveyor 160, thereby advancing the respective cargo item towards the door / opening of the cargo compartment 104. Similarly, cargo item C on the adjacent conveyor 160 is advanced toward the door / opening of the cargo compartment 104. Conveyors 160 within a single cargo compartment or within separate compartment portions have similar construction and operate in substantially the same manner. Thus, unless specifically described as applicable to only one of these end uses, a description of the construction and operation of conveyor 160 also applies to conveyors on the platform or within the cargo compartment / compartment portions.

[0052]

[0063] The two lower levels 104B, 104C are physically separated by conveyors 160 located both above and below these levels of compartment portions. In addition, the two levels 104B, 104C are physically separated by a vertical divider 170, which defines three laterally spaced and physically separated compartment portions in each of these two levels 104B, 104C. It will also be appreciated that each of the compartment portions need not be of equal size (horizontally and / or vertically), but is simply shown to be of equal size for ease of illustration. Also, more or fewer compartment portions may be provided as specifically required depending on the type of cargo C being delivered.

[0053]

[0064] The conveyors 160 for the different compartment portions are preferably driven by separate motors (not shown) or using one or more common motors, where an appropriate proportion of motive power from the motors can be distributed to operate one or more of the conveyors individually and / or simultaneously.

[0054]

[0065] The platform 140 preferably has a conveyor 160, or preferably has first and second conveyors separated by a gap 172 extending in the direction of travel of the respective belts 164 of the platform conveyor. In particular, one or more push bars 180 (FIG. 19) are fixed in a spaced apart arrangement along a flexible drive member, such as a chain 182, which rotates together with the belts 164 of the platform 160. The push bars 180 are dimensioned to extend above the upper surface 164A of the belts 164 of the platform conveyor 160, and preferably, on the return path of the belts on each conveyor, the push bars can automatically move to a position of reduced height or are folded to a position of reduced height so that the push bars do not extend above the lower surface 164B of the belts (FIG. 20). While the push bar 180 can be moved to a folded / inoperative state in different ways, the preferred embodiment has it fixed to a chain 182 that rotates or travels between two conveyors 160 on the platform 140. The push bar 180 is preferably weighted down at one end so that gravity forces it upright when it travels along the top of its rotational path (FIG. 19) (in which it extends vertically from the chain 182 through the gap 172 between the platform conveyors 160) and automatically retracts it when it travels down the path of travel (in FIG. 20, it is generally aligned with the chain and does not extend through the gap). In this way, the push bar 180 can assist in moving cargo C received on the upper surface 164A by physically abutting the edge of the cargo item by a selected height with the upper surface 164A of the moving conveyor 160 and by limiting potential slippage between the cargo item and the upper surface of the platform conveyor. Conversely, during the return path of movement of the conveyor 160 and chain 182, the push bar 180 is automatically retracted so that the push bar does not inadvertently contact anything positioned adjacent the underside of the platform conveyor.

[0055]

[0066] Additionally, a sensor 190 (FIGS. 21-22), such as an optical sensor, directs a light beam across the rear portion of the compartment portion. The sensor can be located in various locations, with the sensor preferably being located at or near the rear end of each compartment portion where the cargo items C will transfer from the compartment portion to the platform 140. By operating the platform conveyor 160 at a higher speed than the individual compartment portion conveyors 160, cargo items C that may have abutted against adjacent cargo items in the individual compartment portion (FIG. 21) will separate to form spaces (FIG. 22) between the individual cargo items C. This is because of the higher speed at which the cargo items transfer onto the platform conveyor 160 and separate from adjacent neighboring cargo items on the conveyor within the compartment portion. This increased speed creates spaces that are detected by the sensor 190, which may result in the movement of the compartment portion conveyor 160 and similar movement of adjacent neighboring cargo items C thereon being stopped. In this way, only the desired cargo item C is transferred onto the platform 140. The platform 140 can then be moved to another compartment portion and the rotational direction of the platform conveyor 160 reversed to load the cargo item C into another compartment portion (FIGS. 7-9), or the platform can be moved to another desired location, such as the ground, where the platform conveyor is then restarted to move or displace the cargo item from the platform (FIG. 12). The push bar 180 ensures effective and efficient removal of the cargo item C from the platform 160. This operation can then be repeated for one or more additional cargo items C, as shown in FIGS. 13-15.

[0056]

[0067] Additionally, one or more of the sensors 190 may be configured to read indicia such as barcode labels or wirelessly detect / read RFID chip information associated with individual cargo items C to identify which cargo items have been transferred to the platform 140. Additionally, it should be appreciated that a controller or processor (computer) (not shown) may be in operative communication with a memory that stores information or data received from the sensors 190 regarding the particular location of the cargo items C within the storage compartment 104 (whether the cargo items have been delivered and / or, if the cargo items have been delivered, the location and time of delivery of the cargo items). In this case, other data or information, such as GPS, etc., and / or date and time information, and / or compartment temperature, may be input into the controller / processor to monitor and track the cart, and some or all of this data / information may be displayed on a suitable display device (not shown) associated with the vehicle or a portable device such as a tablet, smartphone, etc., or may be transmitted in any conventional manner (e.g., wired or wireless) to a remote computer system or device (not shown) and / or may be printed if a hard copy of the information is desired.

[0057]

[0068] All of the motors and sensors associated with the operation of the door, conveyor, conveyor sections, lift assembly, etc. are interconnected to a controller (not shown), which controls the autonomous opening of the door 102 (FIGS. 1 and 2), lowering the lift assembly platform 140 (FIG. 2), moving the platform to a desired location in the storage compartment 104 (FIGS. 3 and 4), loading a cargo item C from a compartment section onto the platform (FIGS. 5 and 6), moving the cargo item to another compartment section (FIGS. 7, 8, and 9), moving the platform to a compartment section to receive another / second cargo item (FIG. 10), and dropping the second cargo item to a desired location, such as the ground, etc. The platform may be programmed to move the platform to a compartment portion for retrieving another / third cargo item (Figure 11), move a second cargo item off the platform and onto the ground (Figure 12), move the platform to a compartment portion for retrieving another / third cargo item (Figure 13), move the third cargo item to a desired location, such as the ground, and move the third cargo item off the platform and onto the ground (Figure 14), move the platform from a placement position (Figure 15) to a storage position (Figure 16), and close the door to the storage compartment (Figure 17).

[0058]

[0069] FIG. 23 shows a lever or pin 192 extending from the storage compartment 104 that is intended to be selectively engaged with the platform 140. The lever 192 is rigidly fixed to one of the vertical channels 114, 116, and in some instances a lever may be fixed to each vertical channel. Thus, when two levers are used, the description of one lever applies to the other. The lever 192 is positioned such that the platform is not engaged with the lever when the platform 140 is moved laterally relative to the storage compartment 104 as described above to load and unload cargo items C into and from various compartment portions of the storage compartment. However, the lever 192 assists in the rotation of the platform 140 from the horizontal deployment position to the vertical storage position (FIG. 1). Specifically, the lever 192 extends rearwardly sufficient so that when an edge of the platform 140 (i.e., the edge adjacent the storage compartment 104) is disposed beneath the lever and the platform is moved upwardly, the lever abuttingly engages the platform to exert a moment, couple, or torque on the platform to pivot or rotate the platform from its horizontally deployed position to its vertically stored position about the horizontal member 124. Typically, when the platform 140 is in use (i.e., when the platform is moved upwardly and downwardly and / or laterally from side to side in its deployed state), an outer lateral portion of the platform is spaced inwardly from the lever 192 so that the platform is not engaged by the lever.

[0059]

[0070] FIG. 24 illustrates a movable storage container or bin C' for storing cargo items therein. The movable storage container C' preferably has one or more doors 302 for accessing the interior storage compartment 300. It is further contemplated that the movable storage container C' has wheels 306 for facilitating the container's pivoting movement on the ground. The movable storage container C' is preferably sized for receipt into and out of the truck bed of a conventional pickup truck 310 (FIG. 25). Furthermore, the movable storage container C' may be loaded and unloaded from the truck 310 using, for example, a loader / unloader of the type shown and described in applicant's application PCT / US19 / 29949, filed April 30, 2019, the entire disclosure of which is expressly incorporated herein by reference. Alternatively, a lift platform 320 associated with the storage building or warehouse W may be positioned at the rear end of the truck 310 so that the movable storage container C' may be unloaded and swung from the truck bed onto the lift platform. The lift platform 320 may then move the storage container C' to a desired storage location within the warehouse W. This allows the consumer to fill or empty the storage container C' at a location away from the warehouse W, and further allows the consumer to use a conventional pick-up truck 130 to transport the movable storage container to the storage facility or warehouse. Using a conventional pick-up truck 310 advantageously allows the consumer to facilitate the movement and storage of cargo items without the need for a special truck.

[0060]

[0071] 26-28 show an alternative assembly 400 for handling the insertion, temporary storage during transport, and removal of cargo from a vehicle cart compartment. This alternative storage compartment system 400 cooperates with the lift assembly 110 (not shown in FIGS. 26-28) described above in connection with FIGS. 1-23. Specifically, the system 400 has first and second parallel elongated support rails 402 that receive opposite ends of rollers 404 that rotate relative to the support rails 402 such that cargo C can be pivoted on the rollers and advanced on the rotating rollers into or out of a truck or trailer compartment (not shown). The support rails are supported in a horizontal position by support legs 406, e.g., at least four support legs provided adjacent each end of the first and second rails. If increased support or stiffness is required, additional support legs 406 can be provided at intermediate locations.

[0061]

[0072] Preferably, a respective flexible drive member 410 is mounted on the first and second support legs 402. In this configuration shown in FIGS. 26-28, the flexible drive member 410 is, for example, a chain, cable, belt, extending in a continuous loop from a forward end of the system 400 to a rearward end of the system 400. The flexible drive member 410 rides in a channel provided in the spaced apart parallel first and second support rails and selectively moves in a clockwise or counterclockwise direction in response to drive output from respective first and second motors 412. In this manner, the first motor 412 drives (rotates) the first flexible drive member 410 forward or backward, and similarly, the second motor 412 drives (rotates) the second flexible drive member 410, either independently of or in conjunction with the first flexible drive member. A first or front fence 420 is mounted on the first flexible drive member 410 and moved forward or rearward by the first flexible drive member 410. Similarly, a second movable fence 422 is attached to the second flexible drive member 410. Thus, each fence 420, 422 is preferably driven along only one end / side portion. For convenience, the fences 420, 422 are driven by respective flexible drive members 410 located on opposite support rails 402. The first and second faces 420, 422 are arranged, positioned or located such that one is in front of the cargo C (e.g., a box) and the other is behind the cargo or box. A first or front fence 420 pushes the cargo C out of the compartment or compartment portion, and a second or rear fence 422 pushes the cargo into the truck or trailer, and specifically into the compartment or compartment portion of the vehicle (truck or trailer).

[0062]

[0073] Using appropriate software instructions, the two fences 420, 422 can be commanded to move towards each other (or one relative to the other) via the drive motor 412 and flexible drive member 410 to apply a preselected compressive force that simultaneously pushes the cargo box, so that the cargo cannot move forward or backward when the vehicle accelerates or brakes. The current draw from each drive motor 412 can be utilized to monitor the "magnitude" of compressive force applied to the cargo, and the software will command the drive motor / flexible drive member 410 when desired. Additionally, these fences 420, 422 can work together to move the cargo C forward or backward to place the cargo weight in an ideal or preferred position or location within the vehicle storage compartment.

[0063]

[0074] Whenever the rear fence 422 is moved to the rear of the compartment or vehicle, it flips from a vertical position (cargo engagement position) to a horizontal position (bridge position), allowing the cargo C to be pushed out by the front fence in the vertical position, while the rear fence forms a bridge to the loading platform in the horizontal position. This allows for a smooth transition of the cargo C from the compartment rollers of the system 400 to the loading platform 140 of the lift assembly 110. Additionally, this configuration allows the gap or space between the end of the support rail 402 and the loading platform 140 to receive a roll-up door that operates within the compartment to completely close off access to the compartment.

[0064]

[0075] The rear fence 422 is supported in a vertical position through abutment against the support rail 402, similar to that described for the front fence 420 in FIG. 27. However, as the rear fence 422 reaches the end of the support rail 402 adjacent the rear of the storage compartment, the upper surface of the support rail curves at a transition section 430 and is fed toward the lower surface of the support rail, such that rearward longitudinal movement of the rear fence transitions the orientation of the rear fence from a vertical / cargo-push position (FIG. 26) to a horizontal / bridge position (shown in FIG. 28 as being fed to the horizontal position). Conversely, when the rear fence 422 is advanced longitudinally forward by the flexible drive member, the rear fence travels over the curved transition section, thereby rotating the rear fence from the horizontal bridge position (FIG. 28) to the vertical / cargo-push position (FIG. 26).
