With specific reference to the drawings, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention can be embodied in practice.

[0070] Before at least one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is applicable to other embodiments that can be practiced or carried out in various ways as well as to combinations of the disclosed embodiments. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

[0071] Reference is made to Figs. 1A and IB, which are schematic illustrations of a vehicle 90 having a storage volume 92, and of a system 100 (e.g. displacement system) for moving items 80 assembled within vehicle storage volume 92, according to some embodiments of the invention. Fig. 1A shows a schematic side view and Fig. IB shows a schematic rear view of vehicle 90 and system 100.

[0072] Vehicle 90 may have a storage volume 92. Vehicle storage volume 92 may have a longitudinal direction 92a, a transverse direction 92b and a vertical direction 92c. Vehicle storage volume 92 may have walls, e.g. ceiling 92e, floor 92g, first side wall 92i and second side wall 92k. Vehicle storage volume 92 may have shelves 92m. Shelves 92m may be disposed on the walls, for example, side walls 92i, 92k. Storage volume 92 may store items 80. Items 80 may be stored on or within, for example, shelves 92m, floor 92g or any suitable location within vehicle storage volume 92. Items 80 may include packages, boxes, envelopes, unboxed goods, containers for accommodating goods or any other suitable items.

[0073] Vehicle 90 may be a van. Vehicle 90 may be a delivery van. Vehicle 90 may be a truck. Vehicle 90 may be a van that a person or a robotic system can walk-in (e.g. a walk-in van). Vehicle storage volume 92 may be mounted (e.g. removably mounted) on a chassis 94 of vehicle 90. Vehicle storage volume 92 may be trailed by vehicle 90. While vehicle 90 is described herein as a wheeled vehicle, vehicle 90 may be any land vehicle, airborne vehicle or naval vehicle having storage volume 92.

[0074] System 100 may include one or more automatically controlled mechanical devices 110 (e.g. one or more items manipulators 110) having one or more structures that may engage with items 80. The system may include a controller 120 to control one or more mechanical devices 110, e.g. to load items 80 to selected locations in storage volume 92, unload items 80 from their respective locations within storage volume 92 and/or move items 80 from their respective locations within storage volume 92 to other locations within vehicle storage volume 92. Various embodiments of systems for moving items are described hereinbelow with respect to Figs. 2A- 2G, 3A-3B, 4A-4B, 5A-5B, 6A-6B, 7A-7B, 8A-8B, 9 and 10A-10E.

[0075] During loading of items 80 into vehicle storage volume 92, controller 120 may control one or more mechanical devices 110 to pick up items 80 from a loading location 92o within vehicle storage volume 92 (e.g. near a door of vehicle storage volume 92 or a dedicated loading port of vehicle storage volume 92) or external to vehicle storage volume 92 and move items 80 to selected locations within storage volume 92. Controller 120 may select locations of each of items 80 being loaded into vehicle storage volume 92 based on, for example, weights of the respective items, for example to balance the center of gravity of vehicle 90. Controller 120 may be, for example, disposed within chassis 94 of vehicle 90, e.g. between an upper surface 94a and a bottom surface 94c of chassis 94. Controller 120 may be disposed at various locations within vehicle 90, e.g. within storage volume 92, a driver cabin 96 on one or more components of mechanical device 110 or at any other suitable location.

[0076] During delivery, controller 120 may control one or more mechanical devices 110 to pick up selected items 80 from their respective locations within storage volume 92 and to move selected items 80 to an unloading location 92r within storage volume 92 (e.g. near the door of vehicle storage volume 92 or a dedicated unloading port of vehicle storage volume 92) or external to vehicle storage volume 92. Unloading location 92r may be, for example, the same as loading location 92o. The selection of items for unloading may be based on, for example, a delivery plan, van geolocation data, items identification data, items storage location data and/or any other suitable data. For example, based on the van geolocation data and the delivery plan, controller 120 may select the items that need to be unloaded from vehicle 90 at the next target delivery location. Based on the items storage location data and/or the items identification data, controller 120 may control one or more mechanical devices 110 to pick up selected items 80 from their respective locations within storage volume 92 and move selected items 80 to unloading location 92r within vehicle storage volume 92. Controller 120 may control one or more mechanical devices 110 to move selected items 80 from their respective locations within storage volume 92 to other locations within storage volume 92 to, for example, balance the center of gravity of vehicle 90. Moving selected items 80 to unloading location 92r may be performed by one or more mechanical devices 110 automatically while vehicle 90 is travelling to the next target delivery location such that when vehicle 90 arrives at the next target delivery location selected items 80 will be ready for unloading from unloading location 92r. Selection of items for unloading and movement of selected items 80 to unloading location 92r may be also intimated by an operator (e.g. the driver or the loader). Accordingly, the operator does not need to walk into vehicle storage volume 92 and look for the items that need to be unloaded thus saving time and costs.

[0077] System 100 may include a plurality of sensors 130. Based on signals from sensors 130, controller 120 may identify items 80. Sensors 130 may be disposed on one or more components of one or more mechanical devices 110, items 80 and/or within vehicle storage volume 92 (e.g. on floor 92g, side walls 92i, 92k, shelves 92m or any other suitable location within vehicle storage volume 92). For example, sensors 130 may include radiofrequency transmitters that may read data from radiofrequency identification (RFID) tags; laser readers that may read laser marks; cameras that may read QR codes; or any other suitable sensors that may read identification data. The tags and/or markings may be made on items 80 and/or on floor 92g, side walls 92i, 92k and/or shelves 92m of vehicle storage volume 92. Based on signals from sensors 130, controller 120 may identify selected items 80, identify selected locations with vehicle storage volume 92, identify selected locations on shelves 92 (e.g. empty or occupied locations or spaces) or perform any other suitable action.

[0078] System 100 may include one or more batteries 140. One or more batteries 140 may provide power to components of system 100 (e.g. to one or more components of one or more mechanical devices 110, controller 120, sensors 130 or any other suitable components of system 100). One or more batteries 140 may be, for example, disposed within chassis 94 of vehicle 90, e.g. between upper surface 94a and bottom surface 94c of chassis 94. Having one or more batteries 140 disposed withing chassis 94 may, for example, hollow space within storage volume 92 or cabin 96. One or more batteries 140 may be disposed at various locations within vehicle 90, e.g. within storage volume 92, driver cabin 96, one or more components of one or more components of mechanical device 110 or at any other suitable location. System 100 may include one or more cable guides (not explicitly shown), e.g. to supply power to components of system 100.

[0079] The following illustrations/description depict embodiments of systems for moving items 80. Each of the embodiments may include features from other embodiments presented, and embodiments not specifically described may include various features described herein.

[0080] Reference is made to Fig. 2A, which is a 3D diagram of vehicle 90 and of a system 200 for moving items 80, assembled within vehicle storage volume 92, according to some embodiments of the invention.

In the example of Figs. 2A-2C, linkage 230 includes two scissor linkages 232, 234 coupled to tray 220 at opposing longitudinal ends of tray 220. Linkage 230 may include a single scissor linkages (e.g. one of single scissor linkages 232, 234) coupled to one side of tray 220 (e.g. to which may provide more open tray 220). Linkages other than scissor linkages 232, 234 may be used to couple tray 220 to sliding member 212 and to elevate and lower tray 220 with respect to sliding member 212. For example, linkage 230 may include one or more telescopic arms that may couple tray 220 to sliding member 212 or any other suitable linkage.

[0088] At least part of tray 220 may be rotatable about an axis 221 that is perpendicular (or substantially perpendicular) to tray 220 (e.g. axis 221 as shown in Fig. 2B). For example, tray 220 may be rotatable with respect to sliding member 212 about axis 221. In another example, surface 222 of tray 222 may be rotatable with respect to tray 220 about axis 221.

[0089] System 200 may include an item holder 240. Item holder 240 may be coupled to tray 220. Item holder 240 may engage with items 80. Item holder 240 may hold items 80. In the example of Figs. 2A-2C, item holder 240 includes suction cups 242. Item holder 240 may include devices other than suction cups 242 to engage and/or hold items 80. For example, item holder 240 may include gripping arms, anchors, hook and loop components, or any other suitable devices.

[0090] Item holder 240 may move on tray 220. Item holder 240 may move on tray 220 in directions that are transverse (or substantially transverse) to rail 210. Item holder 240 may move on tray 220 in direction that is parallel (or substantially parallel) to transverse direction 92b of storage volume 92 (e.g. as described below with respect to Figs. 2E, 2F and 2G). For example, tray 220 may include a bar 224 coupled to (e.g. coupled within) tray 220 and being transverse to rail 210, and a slider 226 that may move on bar 224. Item holder 240 may be coupled to slider 226.

[0091] System 200 may include a linkage 250 that may couple item holder 240 to tray 220. For example, linkage 250 may couple item holder 240 to slider 226 of tray 220. Linkage 250 may be extendable and retractable in directions that are transverse to rail 212 (e.g. in directions that are parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92) to move item holder 240 in said directions.

[0092] Linkage 250 may include a first arm 252. First arm 252 may be coupled to slider 226 (e.g. as shown in Figs. 2B and 2C). First arm 252 may rotate with respect to slider 226 about a first arm axis 252a that is perpendicular (or substantially perpendicular) to bar 224 (e.g. as shown in Fig. 2C). Second arm 254 may rotate with respect to first arm 252 about a second arm rotation axis 254a that is parallel (or substantially parallel) to first arm rotation axis 252a (e.g. as shown in Fig. 2C). Second arm 254 may be coupled (e.g. rotatably) to item holder 240 (e.g. as shown in Figs. 2B and 2C). Item holder 240 may include a weight 244 to maintain a vertical (or substantially vertical) orientation of item holder 240 (e.g. as shown in Fig. 2B).

Linkage actuating mechanism may rotate first arm 252 and second arm 254 of linkage 250 (e.g. as shown in Fig. 2C). Linkage actuating mechanism 228 may include a transmission to interconnect first arm 252 and second arm 254. Linkage actuating mechanism 228 may include a motor 228a coupled to slider 226. Motor 228a may cause first arm 252 and second arm 254 of linkage 250 to rotate about first arm rotation axis 252a and second arm rotation axis 254a, respectively, to move item holder 240 in directions transverse to rail 212. For example, linkage actuating mechanism 228 may include a first pulley 228c rotatably coupled to slider 226 and configured to be rotated by motor 228a, a second pulley 228e nonrotatably coupled to second arm 254, and a belt 228g interconnecting first pulley 228c and second pulley 228e. In some embodiments, linkage actuating mechanism 228 includes a transmission gear interconnecting first pulley 228c and second pulley 228e. Second pulley 228e may be disposed along second arm rotation axis 254a (e.g. as shown in Fig. 2D). Second pulley 228e may be circular member formed as integral portion of second arm 254 (e.g. as shown in Fig. 2D). Rotation of first pulley 228c by motor 228a may cause second arm 254 to rotate respect to first arm 252 and further cause first arm 252 to rotate with respect to slider 226 to move item holder 240 in directions that are transverse to rail 212. [0094] Tray 220 may include a transverse slot 223 formed through its surface 222 through which first arm 252 may extend. Linkage 250 may include a second arm 254. Second arm 254 may be coupled to first arm 252 (e.g. as shown in Figs. 2B and 2C). Tray 220 may include a pair of slots 223, a pair of bars 224 and a pair of sliders 226; and linkage 250 may include a pair of first arms 252 and a pair of second arms 254 (e.g. as show in Figs. 2B and 2C).

[0095] Reference is made to Figs. 2E and 2F, which are 2D diagrams of automatically controlled mechanical system 200 of Figs. 2A-2D in operation, according to some embodiments of the invention.

[0096] Linkage 250 may be extendable and retractable in directions that are transverse to rail 212 (e.g. in directions that are parallel to transverse direction 92b of vehicle storage volume 92) to move item holder 240 in said directions. For example, illustrations 2e-l, 2e-2, 2e-3 and 2e- 4 in Fig. 2E show extension of linkage 250 a first transverse direction 92ba (that is parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92) to move item holder 240 in said first transverse direction 92ba. In another example, illustrations 2f-l, 2f-2, 2f-3 and 2f-4 in Fig. 2F show extension of linkage 250 in a second transverse direction 92bc that is opposite to first transverse direction 92ba to move item holder 240 in said second transverse direction 92bc. Linkage 250 may be extendable so as to move item holder 240 beyond outer edges 223 of tray 220 in said directions (e.g. as shown in Figs. 2E and 2F). Linkage 250 may move item holder 240 along a substantially straight line 246 (that is parallel to transverse direction 92b of vehicle storage volume 92; e.g. as shown in Figs. 2E and 2F). Linkage 250 may move item holder 240 at substantially the same height 248 with respect to tray 220 (e.g. as shown in Figs. 2E and 2F).

[0097] Assembling item holder 240 on slider 226 movable on bar 224 in transverse directions 92ba, 92bc using linkage 250 extendable and retractable in transverse directions 92ba, 92bc may provide an extended movement range for item holder 240 to engage with items 80 disposed on shelves 92m and/or floor 92g of vehicle storage volume 92. Configuring linkage 250 to move item holder 240 along substantially straight line 246 and/or at substantially the same height 248 with respect to tray 220 may provide compact system 200. Such system 200 may be easily retrofitted within vehicle storage volume 92 without making any changes (or any significant changes) to vehicle storage volume 92.

[0098] The controller (e.g. such as controller 120 as described above with respect to Figs. 1A and IB) may control components of system 200 (e.g. sliding member 212, linkage 230, slider 226 and linkage 250) to move items 80 within vehicle storage volume 92. [0099] Reference is made to Fig. 2G, which shows 2D diagrams of automatically controlled mechanical system 200 of Figs. 2A-2D in operation within vehicle storage volume 92, according to some embodiments of the invention.

[00100] In operation 2g-l, the controller may control system 200 to bring tray 220 in front of selected item 80. Item holder 240 may be disposed in the middle (or substantially in the middle) of tray 220 between a first lateral edge 223a and a second lateral edge 223c of tray 220 (e.g. wherein second lateral edge 223c is opposing to first lateral edge 223a). In operation 2g-2, slider 226 may be moved along bar 224 in first transverse direction 92ba towards first lateral edge 223a of tray 220 to bring item holder 240 adjacent to first lateral edge 223a of tray 220. In operation 2g-3, linkage 250 may be extended in first transverse direction 92ba to engage with item 80 disposed on shelf 92m. In operation 2g-4, slider 226 may be moved on bar 224 in second transverse direction 92bc towards second lateral edge 223c of tray 220 to pull item holder 240 and item 80 engaged therewith towards tray 220. In operation 2g-5, linkage 250 may be retracted in second transverse direction 92bc to bring item holder 220 adjacent to second lateral edge 223c of tray 220 and to position the entire item 80 engaged with item holder 240 on tray 220. Tray 220 with item 80 disposed on tray 220 and being held by item holder 240 may be further moved towards a desired location (e.g. unloading location 92r) and unload item 80 from tray 220 at the desired location. The unloading of item 80 from tray 220 may be performed by initiating operations 2g- 1 to 2g-5 in a reverse order to that described with respect to Fig. 2G.

[00149] Reference is made to Fig. 9, which is a 2D diagram of a system 900 (e.g. displacement system) for moving items 80 operating in vehicle storage volume 92 and including an item holder 920 movable on a rail 910 and a plurality of extendable surfaces 940 engageable with items 80, according to some embodiments of the invention. Fig. 9 shows a schematic rear view of system 900 and vehicle storage volume 92.

[00150] System 900 may operate as system 100 for moving items 80 within vehicle storage volume 92 (e.g. as described above with respect to Figs. 1A and IB).

[00151] System 900 may include a rail 910 (e.g. such as rail 210 described hereinabove) that may be coupled to ceiling 92e of vehicle storage volume 92 and extending in longitudinal direction 92a of storage volume 92. System 900 may include a sliding member 912 (e.g. such as sliding member 212 described hereinabove) that may be coupled to rail 910 and may move on rail 910 in longitudinal direction 92a.

[00152] System 900 may include an item holder 920. Item holder 920 may engage with items 80. System 900 may include a linkage 930 (e.g. such as linkage 230 described hereinabove) to elevate and lower item holder 920 with respect to sliding member 912. Item holder 920 may be rotatable with respect to sliding member 912 about an axis 921 that is perpendicular (or substantially perpendicular) to rail 910. Item holder 920 may, for example, include gripping arms, anchors, grabber, suction cups or any other suitable device.

[00153] System 900 may include a plurality of extendable and retractable surfaces 940. Extendable surfaces 940 may be coupled to shelves 92m and/or floor 92g of vehicle storage volume 92 (e.g. as shown in Fig. 9). Items 80 may be disposed on extendable surfaces 940. Extendable surfaces 940 may be extended with respect to shelves 92m and/or floor 92g in directions that are transverse to rail 912 and are parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92.

[00154] In operation, extendable surface 940 accommodating selected item 80 may be extended in a direction that is parallel to transverse direction 92b of vehicle storage volume 92 to position selected item 80 below rail 910. Item holder 920 may be moved to position item holder 920 above selected item 80. Item holder 920 may engage with selected item 80. Item holder 920 may be then moved to unload selected item 80 at the desired location.

[00155] Reference is made to Fig. 10A, which is a 3D diagram of vehicle 90 and of a system 1000 (e.g. displacement system) for moving items 80 and including item supports 1005 and a tray 1020 with telescopic bars 1022, assembled within vehicle storage volume 92, according to some embodiments of the invention.

[00156] Reference is made also to Fig. 10B, which is a 3D diagram of shelves 92m of vehicle storage volume 92 and of system 1000 of Fig. 10A, according to some embodiments of the invention.

[00157] Reference is also made to Fig. 10C, which is a 3D diagram of an enlarged region C of Fig. 10B, according to some embodiment of the invention.

[00158] Reference is now made to Figs. 10D and 10E, which are 3D diagrams of a rail 1010, slider 1012, linkage 1030, tray 1020 and telescopic bars 1022 of system 1000 of Figs. 10A- 10C, according to some embodiments of the invention.

[00159] System 1000 may operate as system 100 moving items 80 within vehicle storage volume 92 (e.g. as described above with respect to Figs. 1A and IB). [00160] System 1000 may include a plurality of supports 1005. Supports 1005 may be assembled shelves 92m of vehicle storage volume 92. Supports 1005 may be integrated within shelves 92m. Supports 1005 may be assembled on side walls 92i, 92k of vehicle storage volume 92, e.g. instead of shelves 92m. Supports 1005 may be assembled on floor 92g of vehicle storage volume 92. Supports 1005 may distanced from each other such that hollow space 1006 is formed between adjacent supports 1005. Supports 1005 may be parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92. Items 80 may be placed on supports 1005. Supports 1005 may support items 80. Each of supports 1005 may include an increased friction surface 1005a that contacts items 80 when items 80 are placed on support 1005 (e.g. as shown in Fig. 10C). Increased friction surfaces 1005a may prevent unintended slipping of items 80 from supports 1005. In the example of Figs. 10A-10E, increased friction surfaces 1005a of supports 1005 include saw-tooth structures. Increased friction surfaces 1005a may include other forms of material or shapes than shown in Figs. 10A-10E to increase the friction between surfaces 1005a and items 80.

[00161] System 1000 may include a rail 1010 (e.g. such as rail 210 described hereinabove) that may be coupled to ceiling 92e or floor 92g of vehicle storage volume 92 and may extend in longitudinal direction 92a of vehicle storage volume 92. System 1000 may include a sliding member 1012 (e.g. such as sliding member 212 described hereinabove) that may be coupled to rail 1010 and may move on rail 1010 in longitudinal direction 92a. System 1000 may include a tray 1020. Tray 1020 may receive items 80. Tray 1020 may temporarily accommodate items 80. System 1000 may include a linkage 1030 (e.g. such as linkage 230 described hereinabove) to elevate and lower tray 1020 with respect to sliding member 1012. At least part of tray 1020 may be rotatable about an axis that is perpendicular (or substantially perpendicular) to tray 1020 (e.g. as described above with respect to Figs. 2A-2D).

[00162] Tray 1020 may include one or more telescopic bars 1022. Each of telescopic bars 1022 may be coupled to tray 1022. For example, tray 1020 may include two telescopic bars 1022. Telescopic bars 1022 may be distanced from each other. Telescopic bars 1022 may be parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92. Telescopic bars 1022 may be parallel (or substantially parallel) to supports 1005.

[00163] Each of telescopic bars 1022 may include a first telescopic bar member 1022a that may be coupled to tray 1020 and a second telescopic bar member 1022c that may be extendable and retractable with respect first telescopic bar member 1022a in directions that are transverse (or substantially transverse) to rail 1010 and that are parallel (or substantially parallel) to transverse direction 92b of vehicle storage volume 92. Each of telescopic bars 1022 may include an intermediate telescopic bar member 1022e disposed between first and second telescopic bar members 1022a, 1022c.

[00164] In operation, tray 1020 may be moved to position tray 1020 in front of selected item 80. Second telescopic bar member 1022c may be extended in the direction that is parallel (or substantially parallel) to supports 1005 and may be inserted below selected item 80 into space 1006 between supports 1005 supporting selected item 80. Second telescopic bar members 1022c may be then retracted towards tray 1020 to position selected item 80 within the perimeter of tray 1020. Tray 1020 may be then moved to position unload selected item 80 at the desired location (e.g. as described hereinabove). In some embodiments, tray 1020 is elevated to pick up selected item 80 from supports 1005 by second telescopic bar members 1022c of telescopic bars 1022 prior to retracting second telescopic bar members 1022c towards tray 1020.

[00165] Second telescopic bar member 1022c of each of telescopic bars 1022 may include an increased friction surface 1022ca that contacts items 80. Increased friction surfaces 1022ca may prevent unintended slipping of items 80 from second telescopic bar members 1022c. In the example of Figs. 10A-10E, increased friction surfaces 1022ca of second telescopic bar members 1022c include saw-tooth structures. Increased friction surfaces 1022ca may include other forms of material or shapes than shown in Figs. 10A-10E to increase the friction between surfaces 1022ca and items 80.

[00166] In some embodiments, each of telescopic bars 1022 includes a lifting mechanism to elevate at least second telescopic bar member 1022c with respect to tray 1022 to pick up selected item 80 from supports 1005. In some embodiments, tray 1022 includes a lifting mechanism to elevate telescopic bar 1022 or at least telescopic bar member 1022c with respect to tray 1022 to pick up selected item 80 from supports 1005.

[00167] System 1000 may include additional components that are not shown in Figs. 10A-10E for simplicity. For example, system 1000 may include a controller (e.g. such as controller 120 described above with respect to Figs. 1A-1B), sensors (e.g. such as sensors 130 described above with respect to Figs. 1A-1B), one or more batteries (e.g. such as one or more batteries 140 described above with respect to Figs. 1A-1B) or any other suitable components.
