Description

Technical Field

[0001] The present invention relates to an apparatus for loading a transport container onto a tilt tray or a tilt bed truck or the like.

Background Art

[0002] Goods or marine containers (transport containers) are commonly used for the movement of materials over land by truck, by rail on a railroad car, or by sea on a container ship.

[0003] Transport containers are generally manufactured with sufficient strength to withstand handling, shipping, intermodal transfer, and storage (and are often stacked for transport or storage). A transport container is typically a large reusable steel box used in intermodal transport. In the context of international maritime trade, a "container" or "transport container" is substantially synonymous with an "intermodal cargo container", i.e., a container designed to move from one means of transport to another without unloading or reloading its contents.

[0004] Such transport containers generally have a rectangular parallelepiped configuration to allow stacking of one container on top of another or to support the container on the deck of a ship or on the tray of a transport vehicle such as a railroad car or a road vehicle.

[0005] Transport containers are usually provided in standard lengths of 20 feet (about 6.096 m) or 40 feet (about 12.19 m) and have doors at at least one end to provide access to the interior of the container. Standard-sized containers typically have a width of 8 feet (about 2.438 m) and a height of 8 feet 6 inches (about 2.591 m), although "high cube" containers have a height of 9 feet 6 inches (about 2.896 m).

[0006] Corner fittings or sockets are provided at each external corner of a container by connecting a device for fixing the container to a ship's deck or a vehicle tray or for connecting containers together. The corner fittings include an opening on the underside and at the corner of the container for receiving a rotatable cleat or lug of a rotatable connection device that is receivable within the opening and rotatable to lock the container in a predetermined position. The openings are also provided in the upper, side, and end faces of the container so that containers stacked on top of each other can be locked together, or adjacent containers can be locked together in an end-to-end or side-by-side configuration by similar connecting devices.

[0007] It is necessary to load a land transport container onto the flat bed or tray of a road vehicle, which can be particularly difficult if a crane, container handler, or hoist for lifting the container onto the tray is not available. This type of vehicle has a bed or tray (often configured to be slidably attached to the vehicle chassis) that is tilted to an inclined position, aligned longitudinally with the end of the container, and moved adjacent thereto. A winch cable of a winch attached to the center of the front end of the tilt tray is coupled to the container to winch the container onto the tray.

[0008] It is not uncommon for the end of the container to abut against and catch on the rear end of the tray, thereby preventing the container from being winched onto the vehicle tray. As a result, a large load is placed on the winch, a high tension is placed on the cable, and either the winch or the cable may suddenly fail. In the event that the cable breaks, it can seriously injure nearby people who may be struck by the cable and can be life-threatening.

[0009] Australian Patent No. 2006200964 discloses a long and sturdy tension rod for connecting to corners spaced laterally at one end of a container. A winch cable is attached to the center of the tension rod, and the winch, cable, and tension rod pull the container onto a flatbed tray.

[0010] A similar long and sturdy tension rod is disclosed in Australian Patent No. 2012231771, which focuses on problems related to the reverse process of lowering a container from a flatbed tray. When the container is ready to be lowered from the flatbed tray, the gravitational force acting on the container by tilting the tray may not be sufficient to overcome the frictional force between the bottom of the container and the tray. The container may also have a risk of slipping uncontrollably backward from the tray. Australian Patent No. 2012231771 further discloses a vehicle-mounted ejector for assisting in lowering a shipping container from a flatbed tray.

[0011] It is recognized that it may be difficult to attach the sturdy tension rod to the corners at the lower end of the container. Since the container is very heavy, it may sink into soft ground, or due to the container being placed on the ground by some force, the end of the container may dig into the ground or the ground may be uneven at the end of the container. Naturally, the sturdy tension rod provides a fixed central attachment point for the winch, but due to the sturdy structure of the tension rod, as well as the fixed length and the fixed spacing of the connection points at each end, it may be difficult to connect to the container.

[0012] Also, such a tension rod is heavy enough to require at least two people to move it manually to the position of the ground at the bottom of the container safely, thereby risking injury to the operator or requiring at least two or more people and the associated additional costs.

[0013] Furthermore, when moving to the site to load the container, it is necessary to safely store the sturdy tension rod in the vehicle. Such a tension rod is usually stored in a flatbed tray due to its length, thus occupying space on the flatbed tray where such space may be required for the load.

[0014] References to prior art in this specification are provided for illustrative purposes only and should not be construed as an admission that such prior art is part of the common general knowledge in Australia or elsewhere.

[0015] The present invention seeks to improve one or more of the aforementioned problems or at least provide an alternative thereto. SUMMARY OF THE INVENTION MEANS FOR SOLVING THE PROBLEM

[0080] It should be understood that each embodiment is specifically described and the present invention should not be construed as being limited to any one particular feature or element of the embodiments. The present invention should also not be construed as being limited to any feature of any of the embodiments, or to the variations described in connection with the embodiments.

[0081] FIGS. 1A through 1E show multiple views of connector 10. Connector 10 is for use in moving container 100. For example, connector 10 may be for use in moving container 100 onto or from a vehicle having flatbed tray 40. Container 100 has attachment points 102a, 102b. Attachment points 102a, 102b may be located at its lower corners 104a, 104b. Specifically, container 100 has a first attachment point 102a at a first lower corner 104a. Container 100 also has a second attachment point 102b at a second lower corner 104b.

[0082] Figures 4 and 5 show the appliance 11. The appliance 11 may be referred to as a container moving system 11 and / or a system 11 for moving a container. The appliance 11 includes a connector 10. In particular, the appliance 11 includes two connectors 10A, 10B. The connector 10a may be in the form of the connector 10. The connector 10b may be in the form of the connector 10. In use, one connector 10 is releasably attached to each of the connection points 102a, 102b at the lower corners 104a, 104b of the container 100. That is, each connector 10a, 10b is releasably attached to only one of the lower corners 104a, 104b of the container 100.

[0083] The connector 10 includes a body 12. The connector 10 includes a releasable attachment portion 14. The releasable attachment portion 14 may be referred to as a releasable attachment mechanism. The releasable attachment portion 14 is configured to releasably attach each connector 10 to each connection point 102. In other words, the releasable attachment portion 14 is configured to be able to releasably attach the connector 10 to the connection point 102. The releasable attachment portion 14 is connected to the body 12. In some embodiments, the releasable attachment portion 14 is integrally formed with the body 12. It can be said that the body 12 comprises the releasable attachment portion 14.

[0084] The releasable attachment portion 14 comprises an elongate portion 15. The elongate portion 15 may be referred to as a shaft 15. The shaft 15 extends radially outward from the longitudinal axis 15a. The shaft 15 extends in the longitudinal direction 15b from a first shaft end 17a to a second shaft end 17b. The longitudinal direction 15b is parallel to the longitudinal axis 15a. In other words, the shaft 15 extends along the longitudinal axis 15a. The shaft 15 defines a shaft outer dimension 17c. The shaft outer dimension 17c is the outer dimension of the shaft measured in the radial direction 17d of the shaft 15. The shaft 15 is connected to the body 12. The shaft 15 may be directly connected to the body 12 (for example, by a welding connection between the body 12 and the shaft 15). The shaft 15 can be regarded as part of the body 12.

[0085] The releasable attachment portion 14 includes a protrusion 16. In some embodiments, the protrusion 16 may be referred to as a connection point engagement portion. The protrusion 16 is disposed at an end of the shaft 15. In particular, the protrusion 16 is disposed at the second shaft end 17b. The protrusion 16 extends outward from the central portion 19. In some embodiments, the protrusion 16 extends radially outward from the central portion 19. In some embodiments, the shaft 15 (i.e., the elongate portion 15) can be regarded as part of the protrusion 16. That is, it can be said that the protrusion 16 includes the shaft 15 (i.e., the elongate portion 15). The protrusion 16 is operably connected to the elongate portion 15. The protrusion 16 is configured such that the connector 10 can be releasably attached to the connection point 102.

[0086] As shown in FIG. 1B, the protrusion 16 defines a first outer dimension 16a. The first outer dimension 16a is the dimension of the protrusion 16 when measured within a first direction 16b. The first direction 16b is orthogonal to the longitudinal direction 15b of the shaft. The protrusion 16 defines a second outer dimension 16c. The second outer dimension 16c is the dimension of the protrusion 16 when measured in a second direction 16d. The second direction 16d is orthogonal to the longitudinal direction 15b of the shaft. The second direction 16d is orthogonal to the longitudinal direction 15b of the shaft. The second direction 16d is orthogonal to the first direction 16b. The first outer dimension 16a is greater than the second outer dimension 16c. In other words, the protrusion 16 has a main direction (the first direction 16b) that is longer than the secondary direction (the second direction 16d). The first outer dimension 16a is greater than the shaft outer dimension 17c. In particular, the first outer dimension 16a is greater than the maximum outer dimension of the shaft 17c. That is, the protrusion 16 extends radially outward beyond the outer surface of the shaft. In some embodiments, the second outer dimension 16c is also greater than the shaft outer dimension 17c.

[0087] The protrusion 16 is configured to releasably engage each connection point 102.

[0088] The connector 10 includes a channel 18. The channel 18 is provided between the main body 12 of the connector 10 and the protrusion 16 of the releasable attachment portion 14. In other words, the main body 12 defines the contour of the channel 18. The channel 18 has its contour defined between the protrusion 16 and a part of the main body 12.

[0089] The connection point 102 includes an opening 106. The opening 106 extends from the outer surface portion of the connection point 102 to the inner surface portion of the connection point 102. The opening 106 defines the contour of a channel to the hollow internal volume of the connection point 102 through the wall of the connection point 102.

[0090] As shown in FIGS. 1D and 1E, the opening 106 is sized such that the protrusion 16 can pass through the opening 106 when the protrusion 16 is in the first posture (with respect to the connection point 102). The opening 106 is sized to inhibit movement of the protrusion 16 through the opening 106 when the protrusion is in the second posture (with respect to the connection point 102), as shown in FIGS. 2 and 3. Specifically, the opening 106 defines a first opening dimension 106a. The first opening dimension 106a is the dimension of the opening 106 when measured in the first opening measurement direction 106b. The first opening measurement direction 106b may correspond to the first direction in which the protrusion 16 can be measured.

[0091] In particular, the first opening measurement direction 106b may correspond to the first direction when the protrusion 16 is in the first posture. The opening 106 defines a second opening dimension 106c. The second opening dimension 106c is the dimension of the opening 106 when measured in the second opening measurement direction 106d. The second opening measurement direction 106d may correspond to the second direction in which the protrusion 16 can be measured. In particular, the second opening measurement direction 106d may correspond to the second direction when the protrusion 16 is in the first posture. The second opening measurement direction 106d is orthogonal to the first opening measurement direction 106b.

[0092] The first opening dimension 106a is larger than the first outer dimension of the protrusion 16. The second opening dimension 106c is larger than the second outer dimension 16c of the protrusion 16. In a specific orientation (i.e., the first posture with respect to the connection point 102) as shown in FIG. 1, the protrusion 16 is configured to be inserted through the opening 106.

[0093] As shown in FIG. 1, the protrusion 16 can be inserted into the opening 106 of the corresponding connection point 102 of the container 100. The protrusion 16 can thus be received by the hollow internal volume 102c of the connection point 102. After insertion, the protrusion 16 of the connector 10 can be moved (either translated or rotated) with respect to the connection point 102 such that the wall portion 42 of the connection point 102 is present in the channel 18. FIGS. 2 and 3 show the connector 10 in a position such that the wall portion 42 of the connection point 102 is present within the channel 18 (i.e., the protrusion 16 is in the second posture). The protrusion 16 (and the body 12) can be said to be in an initial state before rotation. The protrusion 16 (and the body 12) can also be said to be in an engaged state after rotation. FIGS. 2 and 3 show the protrusion 16 in the engaged state. When in the engaged state, if the protrusion 16 is moved outward through the opening 106 and away from the connection point 102, the protrusion 16 contacts the inner surface 102d of the connection point 102.

[0094] Preferably, both the body 12 and the protrusion 16 rotate. In other words, the rotation of the body 12 can cause a corresponding rotation of the protrusion 16. However, it will be understood that the protrusion 16 may be arranged to rotate with respect to the body 12.

[0095] The connector 10 includes a locking device 20. The locking device 20 is configured to hold the protrusion 16 to the connection point 102. In particular, the locking device 20 is configured to hold the protrusion 16 to the connection point 102 when the protrusion 16 is in the engaged position. The locking device 20 is configured to at least partially enter the connection point 102 and hold the protrusion 16 to the connection point 102 until the locking device 20 is released.

[0096] The locking device 20 is movable relative to the main body 12. The locking device 20 is configured to selectively hold the protrusion 16 at the connection point 102. For example, when the protrusion 16 is rotated and engaged with the opening 106 to hold the connector 10 to the container 100, the locking device 20 can be actuated to prevent the protrusion 16 (and thus the connector 10) from being released from the container 100 until the locking device 20 is released and the connector 10 is rotated in the reverse direction again to be released from the container 100.

[0097] The connector 10 includes a locking device holding portion 24. The locking device holding portion 24 is configured to facilitate the movement of the locking device 20. The locking device holding portion defines the contour of the hole. The locking device 20 extends through the hole.

[0098] The locking device 20 may include a shaft portion 22. The shaft portion 22 may be referred to as a shaft. The shaft portion 22 is circular and elongated. The shaft portion 22 is arranged to slide within the holding portion 24. The locking device 20 may include a slide lock member or slide bolt 23 (shown in FIGS. 1 to 3) and / or a lobe (shown in FIGS. 7 to 9) configured to be inserted into a part of the opening 106 of the connection point 102.

[0099] The locking device 20 includes a front end portion 25. The front end portion 25 may be referred to as the front end 25. The front end portion 25 is configured to be received within the opening 106 of the connection point 102 to prevent the release of the protrusion 16. The front end portion 25 is configured to be connected to the shaft portion 22. Similarly, the shaft portion 22 is configured to be connected to the front end portion 25.

[0100] The locking device 20 includes a tab, flange, cam or lobe 29. In the illustrated embodiment, the locking device 20 includes a lobe 29. In particular, the front end portion 25 includes or is in the form of a lobe 29. The lobe 29 (within FIGS. 7 to 9) of the locking device 20 is configured to rotate within the connection point 102 and lock the locking device 20 in a predetermined position until it is rotated in the reverse direction to the release position.

[0101] The rear end 26 of the locking device 20 may include a handle portion 28. In the illustrated embodiment, the handle portion 28 is integrally formed with the shaft portion 22. In some embodiments, the handle portion 28 is configured to be connected to the shaft portion 22. The handle portion 28 is disposed at an end opposite to the front end portion 25 of the shaft portion 22.

[0102] As shown in FIGS. 1A to 1E, 2 and 3, in the present embodiment, the handle portion 28 of the locking device 20 is moved forward by pressing movement in order to move the locking device 20 forward toward the protrusion 16. In particular, the front end 25 of the locking device 20 is moved toward the protrusion 16. The front end 25 of the locking device 20 may be rod-shaped such that the front end 25 is rounded as shown in FIGS. 1A to 1E, 2 and 3.

[0103] In another embodiment, as shown in FIGS. 7 to 9, the front end 25 of the locking device 20 includes a lobe 29. The lobe 29 may be attached to the shaft portion 22. The lobe 29 and the shaft portion 22 of the locking device 20 may be integrally formed. The lobe 29 has a flat side as shown in FIGS. 7 and 8. As shown in FIG. 9, the lobe is curved on the side opposite to the flat side, and the curved side and the flat side intersect at the top. Therefore, it can be said that the lobe 29 forms a teardrop shape. The attachment of the lobe 29 to the front end 25 of the locking device 20 is made such that when the handle portion 28 of the connector 10 rotates, the lobe 29 rotates in the same direction as the handle portion 28 accordingly. The holding portion 24 remains stationary, but the locking device 20 is pushed through the hollow holding portion 24. The locking device 20 may also have a stopper 33 that contacts the holding portion 24 when the locking device 20 is pushed through the holding portion 24, and stops the locking device 20 from further advancing when the handle portion 28 is pushed further forward as shown in FIG. 9.

[0104] As shown in Fig. 9, during use, when the handle portion 28 is used to push the lobe 29 forward toward the protrusion 16 (it is not shown that the protrusion 16 rotates once inside the opening 106 by rotating the main body 12), the lobe 29 advances into the opening 106 and rotates so that the flat surface of the lobe 29 contacts the flat surface of the protrusion 16. This suppresses the movement of the lobe 29 and reduces the possibility of the lobe 29 falling out backward from the opening 106. Thereby, it becomes possible to hold the entire instrument 11 in a predetermined position on the lobe 29.

[0105] In the embodiments of Figs. 1A to 3, the locking device includes a pair of protruding features 50A, 50B. The first protruding feature 50 is disposed on one side of the holding portion 24. The second protruding feature 50 is offset from the first protruding feature 50 along the shaft 22 within the longitudinal direction 15b of the shaft. The second protruding feature 50 is disposed on the other side of the holding portion 24. Each of the first protruding feature 50A and the second protruding feature 50B protrudes outward from the shaft 22. The pair of protruding features 50A, 50B are configured to physically limit the longitudinal movement of the shaft 22. These features can reduce the possibility that the locking portion 20 unintentionally detaches from the holding portion 24.

[0106] In the embodiments of Figs. 7 to 9, the main body 12 also has a notch 21 at the edge of the main body 12. The locking device 20 has a protrusion 27 configured to be received by the notch 21. The protrusion 27 may be referred to as a protruding feature. The protrusion 27 is a wedge-shaped protrusion. As shown in Fig. 7, the protrusion 27 is configured to be received by the notch 21 that locks the locking device 20 in a predetermined position when the locking device 20 and the handle portion 28 are housed in the retracted position.

[0107] According to one embodiment during use, when the protrusion 16 is received in the elongated opening 106 of the connection point 102, a vacant portion remains in the opening 106 due to the rotation of the protrusion 16. The locking device 20 is configured to at least partially fill the vacant portion in order to limit or prevent the removal of the protrusion 16 until the locking mechanism 20 is removed from the opening 106.

[0108] The connector 10 includes a body mounting portion 30. The body mounting portion 30 may be for attaching the elongated member 108 to the connector 10. In other words, the body mounting portion 30 is configured to be able to connect the elongated member 108 to the connector 10. Accordingly, the elongated member 108 may be a cable or a chain or a mounting device. The body mounting portion 30 may be a shackle and / or, accordingly, may have an opening 31 for receiving the elongated member 108 or an attachment. The body mounting portion 30 may be held by a holding portion 32 having a loop or an eye 32a that attaches to the body 12 or forms part of the body 12.

[0109] The body mounting portion 30 can be pivotally attached to the body 12, whereby the body mounting portion 30 can pivot toward the body 12 during storage and can extend outward for use when moving or retracting the container 100 onto the flatbed tray 40. Such a pivot arrangement can enable adjustment / variation of the angle of the body mounting portion 30 with respect to the body 12 to accommodate variations in the position of the elongated member 108. The flatbed tray may include elongated guides extending along both sides of the flatbed tray.

[0110] The protrusion 16 defines the contour of the first connection point contact surface 43. The first connection point contact surface 43 is configured to contact the inner surface of the connection point 102. The connector 10 includes an external engagement portion 44. The external engagement portion 44 is configured to engage the outer surface of the connection point 102. In particular, the external engagement portion 44 defines the contour of the second connection portion contact surface 45.

The tail surface 60 is orthogonal to the longitudinal axis of the body 12 of the connector 10.

[0113] It is difficult to perfectly align a flatbed or tray of a road vehicle with a loaded container. Thus, when aligning a flatbed or tray of a road vehicle with a container for the flatbed or tray, it is not uncommon to align the flatbed or tray at a small angle with respect to the longitudinal axis of the container. This angle can make it more difficult to load the container onto the truck because the container 100 can catch on the rear ramp of the vehicle. The tail portion 39 of the connector 10 described herein provides a surface that can be used to align the container with the road vehicle. Specifically, when backing up, the rear ramp of the road vehicle can be lowered to the ground, and the driver of the vehicle can back the road vehicle toward the container 100. When a connector 10 as described herein is connected to the lower corner of the container 100, the rear ramp first contacts one of the tail portions 39 within one of the two associated lower connectors 10. As the truck is backed up further, a force is applied to the tail portion 39, specifically the tail surface 60. This force is transmitted through the connector 10 to the container 100, and the container 100 can be moved into alignment with the vehicle. When the other side of the rear ramp contacts the other connector 10, the container 100 is aligned with the longitudinal axis of the road vehicle.

The remaining portion of the connector 10 may be of a different color than the color of the hook and the attachment portion 30. Similarly, the remaining portion of the elongated member 108 (i.e., the elongated member 108 excluding the hook) may be of a color different from the color of the hook and the attachment portion 30.

[0149] The first connector 10a and the second connector 10b are preferably single-turn, i.e., clockwise or counterclockwise, such that the first connector 10a includes a part of the releasable attachment portion 14 that rotates in a first direction for connecting the connector 10 to the container 100, and the second connector 10b includes a part of the releasable attachment portion 14 that rotates in a direction opposite to the first direction. In an embodiment, all of the first connector 10a and / or all of the second connector 10b are rotated for connection to the container 100.

[0150] Alternatively, in another embodiment, a part of the first connector 10a and / or a part of the second connector 10b are rotated for connection to the container 100.

[0151] The method of loading the container 100 onto the flatbed or tray 40 of a truck includes first attaching each connector 10a, 10b to the first and second connection points 102a, 102b at the respective lower corners 104a, 104b at the ends of the transport container 100. A flexible elongate member 108, such as a chain or cable, is then connected between the first and second connectors 10a, 10b as shown in FIGS. 4 and 5. A winch cable is then connected between the winch of the vehicle and the flexible elongate member 108, and the flatbed or tray 40 is tilted at an angle such that the lower edge of the flatbed or tray 40 engages below the first and second connectors 10a, 10b and / or the lower edge of the container 100, as shown in FIG. 6. This then draws the container 100 onto the flatbed or tray 40 by use of the winch.

[0152] When the container 100 is at least partially loaded onto the flatbed or tray 40, the inclination of the flatbed or tray 40 can be reduced to approach horizontal. The method further includes that the first and / or second connectors 10a, 10b can be rotated for connection to the container 100.

[0153] Moreover, the second connector 10b is rotated in a direction different from the rotation direction of the first connector 10a for releasable engagement with the container 100. Further, the method includes having a portion 16 configured such that the locking device 20 is inserted into the respective connecting device 102 (the connecting device 102 not shown in FIGS. 7, 8, 9). This prevents or minimizes reverse rotation of the connector 10 until each locking device is released.

[0154] The first and second connectors 10a, 10b and the flexible elongate member (e.g., a chain or cable) 108 can be provided as a set of components.

[0155] It will be understood that the connectors 10a, 10b can be separated from each other, i.e., they can be made not to be attached via the elongated member 108. The elongated member 108 can also be left attached to at least one of the connectors 10a, 10b. Each of the connectors 10a, 10b can be easily handled by one person for loading and unloading onto the vehicle.

[0156] It will be understood that one or more forms of the present invention are advantageous for providing efficient loading of a transport container onto a vehicle tilt tray / bed.

[0157] It will be understood that one or more forms of the present invention can be used with transport containers in less than ideal ground conditions, such as soft ground over a long period of time.

[0158] It will be understood that one or more forms of the present invention enable the versatility of a wide range of transport containers of various sizes. Elongated members such as chains and cables are multifunctional and help rescue transport containers from dirty situations.

[0159] The connector is a compact instrument and it will be understood that it is easy to use and store via a truck dog / storage box.

[0160] With the connector, the loading process of the transport container can reduce the risk of safety concerns. For example, it can reduce the risk of being exposed by walking on an inclined / tilted tilt tray (risk reduction).
