TECHNICAL FIELD

The field relates to object manipulation and handling.

BACKGROUND

Transporting objects, e.g., in a logistics network, presents unique challenges. For example, loading, organizing, and staging objects, e.g., in a delivery vehicle, can be complex and time consuming, and often relies on a significant amount of manual handling. This reliance on manual handling in particular may limit the speed and efficiency of such a process. Therefore, improved systems and processes for automated or semi-automated loading, shifting, and staging of objects are needed.

SUMMARY

This summary is intended to introduce a selection of concepts in a simplified form that are further described below in the detailed description section of this disclosure. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in isolation to determine the scope of the claimed subject matter.

In brief, and at a high level, this disclosure describes, among other things, embodiments that support automated and/or semi-automated loading, shifting, staging, and handling of objects in different environments. For example, in one instance, the environment is a storage space, e.g., inside a vehicle or facility, e.g., one associated with a logistics network operation. The implementation of embodiments described herein may increase the speed, efficiency, and precision of object handling in these different environments, among other benefits. In one aspect, a loading mechanism is provided that supports automated and/or semi-automated loading of objects into a storage space, e.g., one inside a vehicle. In another aspect, a shifting mechanism is provided that supports automated and/or semi-automated shifting and staging of objects in a storage space, e.g., one inside a vehicle. In another aspect, a door assembly is provided that supports automated and/or semi-automated opening and closing, e.g., inside a vehicle. In addition to the aforementioned aspects, methods of manufacturing, retrofitting, and operating the same are also provided herein.

The term “object,” as used herein, should be interpreted broadly, to include any one, or combination, of items that may be transported from one location to another. For example, in one non-limiting aspect, an “object” may be a package or parcel with contents intended for a particular destination, e.g., in a logistics network.

The term “logistics network,” as used herein, should also be interpreted broadly, to include any one, or combination, of persons, equipment, locations, and/or mobile transports (e.g., vehicles, railway transports, ships, aircraft, and the like, including those that operate autonomously or semi-autonomously) used to route objects to different destinations.

The term “storage structure,” as used herein, should also be interpreted broadly, to include any structure suitable for receiving and supporting one or more objects during transport. For example, a storage structure may be a rack, cart, or other upright structure that is capable of holding, supporting, storing, and/or securing one or more objects for transport.

Looking at FIG. 2, a system 20 with components 24, 26, 28, 30, 32, 34 that support loading, shifting, staging, and/or handling of objects, e.g., in automated and/or semi-automated fashion, is shown, in accordance with an embodiment hereof. The components 24, 26, 28, 30, 32, 34 are interconnected over a network 22, and may be local, or distributed, or a combination thereof. The selection of components 24, 26, 28, 30, 32, 34 shown in FIG. 2 is intended to represent merely one example, and numerous other combinations are contemplated herein.

The system 20 shown in FIG. 2 includes a control system 34. The control system 34 may monitor, control, and/or direct operation of different components of the system 20. In one aspect, the control system 34 may individually control elements of the system 20. In another aspect, the control system 34 may control multiple elements of the system 20 thereby allowing them to operate in coordination (e.g., to perform associated tasks in combination or in sequence). The components 24, 26, 28, 30, 32 shown in FIG. 2 may be controlled locally, remotely, and/or through a distributed configuration, in different embodiments. The control system 34 may include computing components, processors, and/or systems that monitor, direct, and/or otherwise operate to control the components of the system 24, 26, 28, 30, 32, either separately, or in coordination, as described herein.

The system 20 shown in FIG. 2 includes a loading mechanism 24. The loading mechanism 24 includes components that enable it to engage, support, lift, and translate objects, e.g., storage structures, e.g., into a storage space or staging area. The loading mechanism 24 may be installed in a facility, or in a mobile transport, such as a delivery vehicle, among other locations. The loading mechanism 24 may include, in different embodiments, tracks, guides, actuators, sensors, control systems, power sources, and/or other components that support its operation. The loading mechanism 24 may also be coupled, directly or indirectly, to a shifting mechanism, e.g., the shifting mechanism 26 shown in FIG. 2. In such configurations, the loading mechanism 24 can exchange objects, e.g., storage structures, with the shifting mechanism 26. In one embodiment, the control system 34 may direct operation of the loading mechanism 24, among other components of the system 20.

The system 20 shown in FIG. 2 also includes a shifting mechanism 26. The shifting mechanism 26 includes components that enable it to engage, support, and shift objects, e.g., storage structures, e.g., in a storage space or staging area. The shifting mechanism 26 may be installed in a vehicle, or in a facility, among other locations. The shifting mechanism 26 may, in different embodiments, include tracks, actuators, mechanisms, sensors, control components, power components, drive systems, and/or other mechanical, electrical, and/or pneumatic components that allow it to shift objects to different locations in a storage space or staging area. In some embodiments, the shifting mechanism 26 is configured to interact with other components/systems. For example, the shifting mechanism 26 may include an interface that enables interaction with the loading mechanism 24. The interface may allow objects, e.g., storage structures, to be transferred between the loading mechanism 24 and the shifting mechanism 26. In one embodiment, the control system 34 may direct operation of the shifting mechanism 26, among other components of the system 20.

The system 20 shown in FIG. 2 also includes a door assembly 28. The door assembly 28 can be operated to open and close a door, e.g., in automated or semi-automated fashion. The door assembly 28 may include, in different embodiments, tracks, frames, engaging elements, sensors, actuators, and/or other mechanical, electrical, and/or pneumatic components that operate to open and close a door, or multiple doors, e.g., in automated or semi-automated fashion. The door assembly 28 may be located in a mobile transport, e.g., a vehicle, e.g., being located at a bulkhead of the vehicle between a cab and a storage space. In this respect, the door assembly 28 may be implemented in any type of mobile transport, e.g., a vehicle, ship, railway transport, or aircraft. In one embodiment, the control system 34 may direct operation of the door assembly 28, among other components of the system 20.

In one embodiment, the loading mechanism 24, the shifting mechanism 26, and/or the door assembly 28 may operate in coordination, thereby enabling coordinated loading, shifting, and staging/accessing of objects using the system 20.

In another embodiment, the loading mechanism 24, the shifting mechanism 26, and/or the door assembly 28 may operate, or be directed to operate, e.g., by the control system 34, based on a geographic location or planned geographic location of the vehicle.

The system 20 shown in FIG. 2 also includes a mobile transport 30. The mobile transport 30 may be a vehicle, ship, aircraft, railway transport, or another type of mobile transport. In one embodiment, the mobile transport 30 may be one that operates in connection with a logistics network. The mobile transport 30, in different aspects, may have incorporated therein, or integrated therewith, any of the components 24, 26, 28, 32, 34 described in connection with FIG. 2. In different aspects, the mobile transport 30 may be manually operated, autonomously operated, or semi-autonomously operated, e.g., being directed, at least in part, by a computing device. In one aspect, operation of the mobile transport 30 or operation of the components 24, 26, 28, 32, 34, may be controlled, at least in part, by the control system 34.

The system 20 shown in FIG. 2 also includes a mobile device 32. The mobile device 32 may be used in connection with the components 24, 26, 28, 30, 34 of the system 20. For example, in one aspect, the mobile device 32 may interact with the control system 34 to control operation of the components 24, 26, 28, 30, 34. The mobile device 32 may be at least partially integrated with the mobile transport 30, or distinct, e.g., being portable.

Looking at FIGS. 3-5, a system 36 for loading, shifting, and staging objects is provided, in accordance with an embodiment hereof. FIG. 3 primarily depicts one end 38 of the system 36. FIG. 4 primarily depicts an opposite end 40 of the system 36. FIG. 5 primarily depicts an underside 35 of the system 36. In one instance, the system 36 may be used in a logistics network. For example, the system 36 may be incorporated into a mobile transport, e.g., a delivery vehicle, e.g., one that operates in the logistics network. The system 36 is configured to receive, shift, and stage a plurality of storage structures 44, as shown in FIGS. 3-5. The storage structures 44 may be used to transport objects, e.g., parcels or packages, to designated destinations, e.g., in the logistics network. The system 36 shown in FIGS. 3-5 is intended to represent one example configuration. However, many other configurations are contemplated herein.

Looking specifically at FIG. 3, a loading mechanism 42 is shown, in accordance with an embodiment hereof. The loading mechanism 42 is located at the end 38 of the system 36. The loading mechanism 42 is designed to receive a storage structure 44, lift the storage structure 44 to an elevated position, and then shift the storage structure 44 into engagement with a shifting mechanism 46 coupled to the loading mechanism 42. To enable this, the loading mechanism 42 includes a platform 48 with a track 50. The track 50 includes a pair of elongated track elements 52, 54. The elongated track elements 52, 54 are spaced apart on the platform 48. The loading mechanism 42 also includes a lift mechanism 45 that has an actuator assembly 64 (shown most clearly in FIGS. 11-13). The actuator assembly 64 is operable to shift the track 50, and in particular the track elements 52, 54, along an axis 60, i.e., toward and away from the shifting mechanism 46. The loading mechanism 42 also includes an actuator assembly 66 (shown most clearly in FIGS. 11-13). The actuator assembly 66 is operable to shift the platform 48 along an axis 62, i.e., up and down relative to the shifting mechanism 46. The axis 62 is generally perpendicular to the axis 60. The actuator assembly 66 allows a storage structure 44 supported on the platform 48 to be raised toward the shifting mechanism 46, and the actuator assembly 64 allows the raised storage structure 44 to be shifted into engagement with the shifting mechanism 46. The loading mechanism 42 also includes a storage structure 68 extending generally upward along the axis 62. The storage structure 68 supports the platform 48 and the actuator assemblies 64, 66. In addition, while not depicted, a control system may be connected to the loading mechanism 42 and components thereof. The control system may be used to control operation of the loading mechanism 42, e.g., in coordination with other components of the system 36.

Looking at FIG. 4, the other end 40 of the system 36 is shown, in accordance with an embodiment hereof. FIG. 4 depicts a door assembly 70 that forms part of the system 36. The door assembly 70 is coupled to the shifting mechanism 46 at the end 40, opposite to the loading mechanism 42. The door assembly 70 has a pair of movable doors 71, 73. The door assembly 70 further includes a door-engaging mechanism 75 (which is partially obscured in FIG. 4) coupled to the doors 71, 73. The doors 71, 73 are depicted as sliding doors that are mounted on a track 78. The door-engaging mechanism 75, depending on the configuration, may be operable to engage and shift, e.g., open and close, the doors 71, 73, e.g., in automated or semi-automated fashion, as described in detail in connection with FIGS. 14-18.

Looking specifically at FIG. 5, an underside of the system 36 is shown, in accordance with an embodiment hereof. FIG. 5 shows the configuration of the shifting mechanism 46 in detail. The shifting mechanism 46 includes multiple components that operate in coordination to reposition the storage structures 44 at different locations. In addition, the shifting mechanism 46 is also designed to interact with the loading mechanism 42, e.g., by receiving, engaging, and then shifting storage structures 44 provided by the loading mechanism 42, and is further designed to interact with the door assembly 70, e.g., by staging storage structures 44 at the door assembly 70. The shifting mechanism 46 may be directed by a control system, e.g., as described in connection with FIG. 2. In different embodiments, the control system may be local to the system 36 or remote from the system 36, or some combination thereof.

Looking still at FIGS. 3-5, it can be seen that the shifting mechanism 46 includes a track 74 and a plurality of shifting structures 76. The plurality of shifting structures 76 are coupled to, and are translatable along, the track 74. In addition, each shifting structure 76 is designed to support and secure a storage structure 44, e.g., one introduced by the loading mechanism 42. In this respect, the shifting structures 76 each include components and/or mechanisms that enable releasable securement of the storage structures 44 thereon. The shifting mechanism 46 further includes a shifter assembly 80 and a shifter assembly 82. The shifter assembly 80 is operable to shift the plurality of shifting structures 76 along the axis 60, as identified in FIGS. 3-5. The shifter assembly 82 is operable to shift the plurality of shifting structures 76 along the axis 58, as identified in FIGS. 3-5. As shown in FIGS. 3-5, the axis 58 and the axis 60 are generally perpendicular to each other. This orientation of the shifter assemblies 80, 82 allows the shifting structures 76, and any storage structures 44 mounted thereon, to translate in different directions within the system 36. To enable this multi-directional shifting, the shifting structures 76 are able to transfer between the shifter assembly 80 and the shifter assembly 82 during operation of the shifting mechanism 46. This process is described in detail in connection with FIGS. 8-10.

In one embodiment, the system 36, including the loading mechanism 42, the shifting mechanism 46, and the door assembly 70 are directed by a control system. Depending on the configuration, the control system may direct operation of the components individually, or in coordination (e.g., allowing for simultaneous operation and interaction).

In another embodiment, a control system may direct operation of the loading mechanism 42, the shifting mechanism 46, and/or the door assembly 70 based on a geographic location of the system 36, or a geographic location of a mobile transport that incorporates the system 36. For example, the geographic location of a mobile transport, e.g., delivery vehicle, may be determined using a global positioning system (“GPS”), wireless communication system, telematics, and/or another location-tracking technology or system. Based on the location information, the control system may direct the system 36 to perform different operations. For example, when approaching a particular location, the shifting mechanism 46 may operate to shift a particular storage structure 44 to the door assembly 70, e.g., to allow a delivery driver to quickly and easily access objects stored on the storage structure 44.

Looking at FIG. 6, the shifting mechanism 46 initially shown in FIGS. 3-5 is depicted in isolation, in accordance with an embodiment hereof. FIG. 6 shows how the track 74 extends throughout a staging area 72. The staging area 72 is sized to accommodate the storage structures 44 when mounted on the shifting structures 76, providing sufficient room such that the storage structures 44 can shift around the staging area 72 during operation of the shifting mechanism 46. The staging area 72 is also enclosed by a frame 84. In different embodiments, the frame 84 may be integrated with, and/or form part of, a mobile transport, e.g., a delivery vehicle. The frame 84 includes a track 86 positioned opposite to the track 74. The tracks 74, 86 may be used in combination to support, enclose, and guide the storage structures 44 about the staging area 72, e.g., securely during transit of an associated mobile transport.

FIG. 6 also depicts the shifter assemblies 80, 82 in detail. The shifter assemblies 80, 82 are located adjacent, e.g., directly below, the track 74. The shifter assembly 80 extends across opposite sides of the shifting mechanism 46, generally along the axis 60. The shifter assembly 82 extends across the shifting mechanism 46 generally along an orthogonal axis, i.e., along the axis 58. The shifter assemblies 80, 82 each translate their respective components along these axes 58, 60 to impart translation forces along such axes 58, 60. In this respect, the shifter mechanism 80, and the shifter mechanism 82, each include a plurality of individual sub-mechanisms that operate to translate their associated components along a common axis, e.g., along the axis 60 for the shifter assembly 80, or along the axis 58 for the shifter assembly 82. In the embodiment shown in FIG. 6, each individual mechanism is a belt-driven mechanism 88. However, different mechanisms that utilize different mechanical, electrical, and/or pneumatic components are also contemplated herein. In addition, in different embodiments, each shifter assembly 80, 82 may include any number of belt-driven mechanisms 88 that extend along the common axis 58 or 60, in spaced relation. This number may be selected based on the desired cross-shifting capability within the system.

The belt-driven mechanisms 88 of the shifting mechanism 46 may be located adjacent, e.g., directly below, the track 74, as shown in FIG. 6. The belt-driven mechanisms 88 shown in FIG. 6 each include a belt 85 and a plurality of engaging elements 96 (e.g., structures having a recess, indentation, or feature that is C-shaped or U-shaped) mounted on the belt 85. During operation of a belt-driven mechanism 88, the belt 85 is translated in a continuous fashion, e.g., over powered or idling rollers. This, by association, translates the plurality of engaging elements 96 mounted on the belt 85 along the corresponding axis of operation, e.g., the axis 60 for the shifter mechanism 80, or the axis 58 for the shifter mechanism 82. The shifting structures 76 each include an elongated extension 90 that extends toward the shifter assemblies 80, 82. The elongated extension 90 is configured so that it can be received in any of the plurality of engaging elements 96. The elongated extension 90 can therefore engage with a plurality of engaging elements 96, and after doing so, be shifted by the associated belt-driven mechanism 88 along the corresponding axis of operation, e.g., the axis 60 for the shifter assembly 80, or the axis 58 for the shifter assembly 82. This process is described in further detail in connection with FIGS. 8-10.

Looking at FIGS. 7A-7B, part of the shifting mechanism 46 shown in FIG. 6 is provided, in accordance with an embodiment hereof. FIG. 7A depicts part of the track 74, showing how it extends around the staging area 72. FIG. 7A also depicts the shifting structures 76 that translate along the track 74 during operation of the shifting mechanism 46. FIG. 7A also depicts part of the shifter assembly 80 and the shifter assembly 82, each having their associated belt-driven mechanisms 88, discussed in connection with FIG. 6. It should be noted that in different embodiments, perpendicular shifter assemblies, e.g., such as the shifter assemblies 80, 82 shown in FIG. 7, may include different numbers of belt-driven mechanisms, e.g., such as the belt-driven mechanisms 88, to facilitate shifting of objects along corresponding axes of operation, e.g., at spaced intervals. In other words, a shifting mechanism may be configured so that a desired number of pathways for shifting along one axis are provided and a desired number of pathways for shifting along another perpendicular axis are provided (e.g., a 2×2, 2×4, 2×8, 4×4, 4×8 or another configuration of orthogonally oriented mechanisms is contemplated herein).

The shifting structures 76 shown in FIG. 7A each include an engaging mechanism 92. The engaging mechanism 92 allows a storage structure 44 to be securely coupled to the shifting structure 76. To enable this, the engaging mechanism 92 includes a plurality of adjustable, e.g., depressible, retractable, or actuatable, elements 94. The plurality of elements 94 extend along opposite sides of each shifting structure 76. In one embodiment, in a resting state, the plurality of elements 94 naturally bias outward. This bias may be provided using springs, magnets, and/or other mechanical, electrical, hydraulic, and/or pneumatic actuators integrated with the engaging mechanism 92, in different embodiments. The engaging mechanisms 92 are designed to engage a corresponding feature located on a storage structure 44, as described below.

During a shifting operation, a storage structure, such as the storage structure 44 shown in FIGS. 3-5, can be coupled to, and shifted on, the shifting structure 76, shown in isolation in FIG. 7B. In one embodiment, each storage structure 44 may include a base 37 with a plurality of apertures 35 extending along opposite sides of the base 37, as shown in FIG. 7B. The shifting structures 76, one of which is also shown in isolation in FIG. 7B, each include the engaging mechanism 92, which has the plurality of elements 94 located along opposite sides of the engaging mechanism 92, their position corresponding to the location of the plurality of apertures 35 formed in the base 37. With this corresponding configuration, the shifting structure 76 is able to receive, engage, and support the base 37, and by association, the support structure 44 coupled thereto, during a loading and shifting process, an example of which is described below.

The following illustrates an example process of loading, engaging, and shifting the example storage structure 44. First, the storage structure 44 is positioned for engagement with the shifting structure 76, e.g., using the loading mechanism 42. In one instance, the loading mechanism 42 advances the storage structure 44 onto the engaging mechanism 92, e.g., by shifting the track 50 shown in FIG. 3 toward the engaging mechanism 92. This interaction actuates, e.g., depresses, the plurality of elements 94 on the engaging mechanism 92 (the plurality of elements 94 may alternatively be retracted through operation of components internal to the engaging mechanism 92). Then, once the storage structure 44 is positioned so that a plurality of apertures (e.g., such as the apertures 35 shown in FIG. 7B) on a base (e.g., such as the base 37 shown in FIG. 7B) of the storage structure 44 are aligned with the plurality of elements 94 on the engaging mechanism 92, the plurality of elements 94 are extended, e.g., either through retracting the track 50 to de-engage it from the plurality of elements 94, or otherwise through actuating or de-actuating elements internal to the engaging mechanism 92. This results in the plurality of elements 94 extending outward, and into the plurality of apertures at the base of the storage structure 44. This engagement couples the shifting structure 76 and the storage structure 44 together, allowing the shifting structure 76 to translate about the track 74 in tandem with the storage structure 44.

Looking at FIGS. 8-10, the belt-driven mechanisms 88 associated with the shifter assemblies 80, 82 are shown, in accordance with an embodiment hereof. FIGS. 8-10 depict different perspectives of the belt-driven mechanisms 88 associated with the shifting mechanism 46 shown in detail in FIG. 6.

Looking specifically at FIG. 8, it can be seen that the belt-driven mechanisms 88 each include a similar set of components that support operation thereof. For example, each belt-driven mechanism 88 includes a belt 95. In addition, each belt 95 includes a plurality of engaging elements 96 attached to the belt 95. The plurality of engaging elements 96 each have an opening 98 that is oriented perpendicular to the general direction of translation of the belt 95. Due to this configuration, an object, e.g., the elongated extension 90 of the shifting structure 76 shown in FIG. 6, is able to be received in the opening 98 of the engaging element 96, in a direction perpendicular to the general direction of translation of the belt 95. This direction along which the object, e.g., the elongated extension 90 shown in FIG. 6, can enter/exit the opening 98 is shown by the arrows 100 provided in FIG. 9.

Looking specifically at FIG. 9, once an object, e.g., the elongated extension 90 shown in FIG. 6, is received in the plurality of engaging elements, sides 102, 104 of the engaging element 96 (only one pair of which are identified in FIG. 9 for explanation purposes) are able to translate a force from the belt 95 to the object, e.g., elongated extension 90, thereby shifting it in a general direction of translation of the belt 95. This causes the associated shifting structure 76 and any storage structure 44 supported thereon to be shifted along the general direction of translation of the belt 95. Depending on which belt-driven mechanism 88 is performing the shifting, the translation occurs along the axis 60, or the axis 58, as identified in FIGS. 8-10.

Looking specifically at FIGS. 9 and 10, it can be seen how the belt-driven mechanisms 88, and specifically those oriented perpendicular to each other, are positioned at different heights along the axis 62. This configuration allows an object, e.g., the elongated extension 90, to be translated along one axis 60 using an engaging element 110 of one belt-driven mechanism 106, and then be transferred into a perpendicularly oriented engaging element 112 located on another belt-driven mechanism 108 that is oriented perpendicular to the belt-driven mechanism 106. The object can then be shifted by the engaging element 112 along the axis 58, out of the engaging element 110, and along a new direction. The reverse is also possible, depending on the direction of rotation of the belts 95. This transfer, or “handoff” process for the object, e.g., the elongated extension 90 shown in FIG. 6, allows for continuous shifting of the storage structures throughout the staging area 72, both along the axis 58 and the axis 60. FIGS. 8-10 further depict a series of actuators 114 coupled to the belt-driven mechanisms 88 that translate the associated belts 95 during operation of the shifting mechanism 46.

Looking at FIGS. 11-13, the loading mechanism 42 depicted originally in FIG. 3 is shown in isolation, in accordance with an embodiment hereof. FIG. 11 depicts a perspective view of the loading mechanism 42. FIG. 12 depicts an enhanced view of part of the loading mechanism 42. FIG. 13 depicts the platform 48 of the loading mechanism 42. The loading mechanism 42 shown in FIGS. 11-13 is intended to represent one example configuration, and numerous others capable of achieving the same functionality are contemplated herein.

The loading mechanism 42 shown in FIGS. 11-13 includes a storage structure 68, a platform 48, and a lift mechanism 45. The platform 48 includes a track 50 that includes a pair of elongated track elements 52, 54 that are spaced apart on the platform 48. The track elements 52, 54 are translatable along the axis 60, i.e., generally toward and away from the storage structure 68, through operation of the actuator assembly 64, shown in FIG. 12. The lift mechanism 45 includes an actuator assembly 66 that is operable to translate the platform 48 along the axis 62, i.e., between a lowered position and a raised position. The storage structure 68 extends generally along the axis 62. The loading mechanism 42 also includes a shifter assembly 116 that is operable to shift components along the axis 60, thereby allowing an object, e.g., the storage structure 44 shown in FIGS. 3-5, to be shifted from the track 50 into a staging area, e.g., where a shifting mechanism, such as the shifting mechanism 46 shown in FIGS. 3-5, is located.

Looking still at FIGS. 11-13, the lift mechanism 45 is designed so that a storage structure, e.g., the storage structure 44 shown in FIGS. 3-5, can initially be loaded onto the platform 48 where it is supported by the track 50 and track elements 52, 54 thereof. The actuator assembly 66 may then be operated to translate the platform 48, including the track 50, along the axis 62, i.e., from a lowered position to a raised position. The raised position, generally speaking, may be one that aligns the track 50 and track elements 52, 54 thereof with the shifter assembly 116 shown in FIG. 11. The actuator assembly 64 can then be operated to shift the track 50, e.g., with the storage structure 44 supported thereon, along the axis 60, i.e., shifting it towards the shifter assembly 116 shown in FIG. 12. The shifter assembly 116 may then be operated to further shift the storage structure into a staging area, e.g., the staging area 72 with the shifting mechanism 46 shown in FIGS. 3-5. In different aspects, the shifter assembly 116 may directly engage, and/or operate in coordination with, the track 50 and/or the track elements 52, 54.

Looking at FIG. 13, it is shown how the track elements 52, 54 extend across the platform 48. In addition, the track elements 52, 54 are spaced apart on the platform 48, allowing them to support the base of a storage structure, e.g., the storage structure 44 shown in FIGS. 3-5. The track elements 52, 54 are each coupled to a corresponding guide track 118, 120 that is fixed to the platform 48. During operation of the actuator assembly 64, the track elements 52, 54 can shift along their corresponding guide track 118, 120, i.e., back and forth along the axis 60. For example, when the track 50 is in alignment with the shifter assembly 116, this actuation allows a storage structure supported on the track elements 52, 54 to be shifted toward, e.g., into engagement with, the shifter assembly. The track elements 52, 54 also each include a corresponding surface 124, 126 that is angled, or slanted, relative to the axis 60 along which the track elements 52, 54 slide. These angled/slanted surfaces 124, 126 allow the track elements 52, 54 to progressively engage components located on a shifting structure, e.g., such as the engaging elements 94 located on the engaging mechanism 92 forming part of the shifting structure 76 shown in FIG. 7A. The platform 48 of the loading mechanism 42 also includes a door 128. The door 128 is pivotably coupled at an end of the platform 48. The door 128 is pivotal between a position that is generally parallel with the axis 62 and a position that is generally parallel with the axis 60. The door 128 can be used to secure/enclose structures positioned on the platform 48 during operation of the lift mechanism 45.

Looking still at the loading mechanism 42 shown in FIGS. 11-13, it can be seen how the actuator assembly 64 and the actuator assembly 66 each include different components that support their operation. For example, this may include belt-driven mechanisms, linear actuators, power components, and/or control components, among other possible components. In the embodiment shown in FIGS. 11-13, the actuator assemblies 64, 66 each include a corresponding belt-driven mechanism 122, 123 that is used to translate components. The belt-driven mechanisms 122, 123 each include a belt, at least two rollers over which the belt is positioned, and at least one rotational actuator that rotates the belt during operation of the belt-driven mechanisms 122, 123.

In different embodiments, the operation of the actuator assemblies 64, 66 and the shifter assembly 116 shown in FIGS. 11-13 may be directed by a control system. The control system may be connected to each of the assemblies 64, 66, 116, and may be local to the loading mechanism 42 and/or an associated mobile transport, and/or remote from the loading mechanism 42 and/or an associated mobile transport. The assemblies 64, 66, 116 may operate in automated or at least partially automated fashion, e.g., at the direction of the aforementioned control system. In one instance, the operations may be directed by a remote computing device that monitors and controls multiple components, e.g., the shifting mechanism 46 and door assembly 70.

Looking at FIGS. 14-18, a door assembly 130 is provided, in accordance with an embodiment hereof. The door assembly 130 shown in FIGS. 14-18 is intended to represent one example configuration, with numerous others being contemplated herein. FIG. 14 depicts one side 132 of the door assembly 130. FIG. 15 is an enhanced depiction of part of the door assembly 130 shown in FIG. 14. FIG. 16 depicts another side 134 of the door assembly 130. FIG. 17 depicts part of the door assembly 130 shown in FIG. 16. FIG. 18 is another enhanced depiction of the door assembly 130 shown in FIG. 16. In one embodiment, the door assembly 130 may be integrated into a mobile transport, such as the vehicle 174 shown in FIG. 19. This integration may be provided through integral assembly/design, or through retrofitting an existing door assembly located in a vehicle.

Looking at FIG. 14, the door assembly 130, and in particular, the side 134 of the door assembly 130, is shown, in accordance with an embodiment hereof. The door assembly 130 includes a frame 140. The door assembly 130 also includes a pair of doors 136, 138 that are slidably coupled to respective tracks 142, 144 that extend along a top of the frame 140. The door assembly 130 further includes a door-shifting mechanism, variations of which are shown in FIGS. 16 and 18. In one embodiment, the door-shifting mechanism is an actuator 148, as shown in FIG. 18, that operates to shift the doors 136, 138 open and closed, e.g., at the direction of a control system. In another embodiment, the door-shifting mechanism includes movable components, e.g., as shown in FIG. 16, that operate to engage and translate the doors 136, 138 between a closed configuration and an open configuration, e.g., at the direction of a control system.

The door assembly 130 may be configured to operate in automated or semi-automated fashion. For example, a control system may be communicatively connected to components of the door assembly 130. In addition to controlling the door assembly 130, the control system may direct other loading, shifting, and/or staging components, e.g., allowing these systems to operate in coordination. This automated or semi-automated operation may impart greater efficiency to a loading, staging, and delivery sequence, e.g., one performed in a logistics network operation. In one instance, the door assembly 130 may be integrated into a delivery vehicle. Then, while the delivery vehicle travels a delivery route, a control system directs a shifting mechanism, such as the shifting mechanism 46 shown in FIGS. 3-5, to operate and re-organize a plurality of storage structures, e.g., the storage structures 44 shown in FIGS. 3-5, positioning a particular storage structure at the door assembly 130. The particular storage structure may be staged based on the vehicle approaching or arriving at a delivery destination associated with one or more objects stored on the storage structure. Upon arrival, the door assembly 130 may open in automated or semi-automated fashion to provide efficient access to the staged storage structure. This process may be repeated as the vehicle makes multiple delivery stops and thereby increase the speed and efficiency of a delivery operation.

Looking at FIG. 15, part of the door assembly 130 is shown, in accordance with an embodiment hereof. FIG. 15 shows the doors 136, 138 coupled to the frame 140 at the tracks 142, 144. The tracks 142, 144 may each include an elongated slot (not shown in FIG. 15) through which guides 150, 152 are respectively extended, and supported, allowing the doors 136, 138 to slide back and forth, e.g., in response to operation of a door-shifting mechanism.

Looking at FIG. 16, the side 134 of the door assembly 130 is shown, in accordance with an embodiment hereof. In one embodiment, the door assembly 130 may be integrated into a vehicle, where the side 134 is oriented to face a storage area in the vehicle, and the side 132 is oriented to face a cab in the vehicle. In a further embodiment, the storage area may include a shifting mechanism, e.g., such as the shifting mechanism 46 shown in FIGS. 3-5, that stages storage structures at the door assembly 130. The embodiment depicted in FIG. 16 includes a door-shifting mechanism 147 that is configured to engage and operate the doors 136, 138, as discussed further below.

The door-shifting mechanism 147 encompasses a series of elements that are used to open and close the doors 136, 138, e.g., in automated or semi-automated fashion. The doors 136, 138 each include a respective engaging element 154, 156, as shown in most detail in FIG. 17. The door-shifting mechanism 147 also includes engaging elements 160, 162 that are coupled to respective distal ends 161, 163 of movable members, e.g., multi-axis arms, 155, 157. The movable members 155, 157 are connected to one or more actuators and control components, and may include hinges, linearly-translating elements, and pivot or ball joints, among other features.

Through operation of the door-shifting mechanism 147, the engaging elements 160, 162 can be shifted in different directions, e.g., along the axis 164, 166, and/or 168, depending on the configuration. For example, in one embodiment, the engaging elements 160, 162 may be shiftable along the axis 166 and the axis 168, allowing them to translate into a coupled configuration with the engaging elements 154, 156. The engaging elements 160, 162 can be shifted into contact with the engaging elements 154, 156 through translation along the axis 168, and then the coupled engaging elements 154, 160 and 156, 162 can be shifted along the axis 166, thereby translating the doors 136, 138 between an open configuration and a closed configuration, depending on the direction of actuation. The engaging elements 154, 156, 160, 162 may be male-female couplings, magnetic mechanisms, latching mechanisms, or another form of mechanical, electrical, and/or pneumatic attachment mechanism. In additional embodiments, the engaging elements 160, 162 may simply remain fixed to the engaging elements 154, 156, such that shifting them into contact is not necessary to translate the doors 136, 138.

Looking at FIG. 17, part of the door assembly 130, located on the side 134, is depicted, in accordance with an embodiment hereof. FIG. 17 more clearly depicts the engaging elements 154, 156 mounted on the adjacent doors 136, 138. In this example embodiment, the engaging elements 154, 156 each include a recess 170, 172 that is shaped to receive a corresponding extension located on the engaging elements 160, 162 shown in FIG. 16. In the example of the door assembly 130, the extensions are the engaging elements 160, 162 that are insertable into the recesses 170, 172 along the axis 168, thus allowing a force applied by the engaging elements 160, 162 along the axis 166 to shift the engaging elements 154, 156, and by association, the doors 136, 138.

Looking at FIG. 18, the door assembly 130 is again shown, but with an actuator 148 that forms part of a door-shifting mechanism 145, in accordance with an embodiment hereof. In some embodiments, this configuration may be used for translating the doors 136, 138 along the tracks 142, 144 shown in FIG. 15, e.g., between a closed configuration and an open configuration. In one example, the actuator 148 may form part of a belt-driven assembly coupled to the frame 140 and to the doors 136, 138. In addition, or in the alternative, the movable members 155, 157 of the door-shifting mechanism 147 may be installed as shown in FIG. 16, and controlled/actuated to engage, open, close, and/or disengage the doors. In either instance, the door-shifting mechanisms 145, 147 may operate in automated or semi-automated fashion, e.g., at the direction of a control system.

Looking at FIG. 19, a vehicle 174 with a loading mechanism 176 and a shifting mechanism 178 (shown only in part for clarity) integrated therein is provided, in accordance with an embodiment hereof. While not shown, the vehicle 174 may also include a door assembly, e.g. the door assembly 130 shown in FIGS. 14-18, that may operate in automated or semi-automated fashion, e.g., in coordination with the loading mechanism 176 and the shifting mechanism 178, as described herein. The vehicle 174 and the systems integrated therein may be manually operated, autonomously operated (e.g., being driverless), and/or may be semi-autonomously operated. In one aspect, the vehicle 174 may be retrofitted from its original configuration to include the loading mechanism 176, the shifting mechanism 178, and the door assembly 130, e.g., to upgrade its automation capability for use in a logistics network operation.
