Load fixing method and device

Abstract

Various embodiments of the present disclosure provide load securing devices and methods for securing a load in a shipping container. Generally, each load securing device includes a base and two wings, each wing having an angle engagement end. The wings are attached to the base and are movable relative to each other and to the base from a compact configuration in which a first distance separates the angle engagement ends to a fixed configuration in which a second, larger distance separates the angle engagement ends. Because the load securing device is more compact when the wings are in the compact configuration (compared to the fixed configuration), it is easier to attach to a shipping container, and particularly to a front corner post of a shipping container, than a similar load securing device having immovable wings that are fixed in the fixed configuration.

Description

[0001] Priority claim

[0002] This patent application claims priority to and the benefit of U.S. non-provisional patent application No. 17 / 197,906, filed on March 10, 2021, which claims priority to and the benefit of U.S. provisional patent application No. 62 / 990,126, filed on March 16, 2020, both of which are incorporated herein by reference in their entirety. Technical Field

[0003] The present disclosure relates to load securing devices and methods, and more particularly to load securing devices and methods for securing a load in a shipping container. Background Art

[0004] Companies use shipping containers to transport cargo loads over long distances by ship, rail, or truck. Shipping containers are large, usually metal containers used to hold and transport products for intermodal rail, marine, and road freight applications. Figure 1A A known shipping container 10 is shown, which includes a first side wall 12, a second side wall 14 opposite the first side wall 12, a front end wall 16, a floor 18, a roof 20 opposite the floor 18, a first rear door 22a and a second rear door 22b opposite the front end wall 16, a first front corner post 30 and a second front corner post 40. The first side wall 12 and the second side wall 14 extend vertically between the floor 18 and the roof 20, and the floor 18 and the roof 20 extend horizontally between the first side wall 12 and the second side wall 14. The front end wall 16 extends horizontally between the first side wall 12 and the second side wall 14, and extends vertically between the floor 18 and the roof 20. The first rear door 22a and the second rear door 22b extend horizontally between the first side wall 12 and the second side wall 14 together (when closed), and extend vertically between the floor 18 and the roof 20, respectively. A first front corner post 30 extends vertically and joins the first side wall 12 and the front end wall 16 to form a first front corner of the shipping container 10. A second front corner post 40 extends vertically and joins the second side wall 14 and the front end wall 16 to form a second front corner of the shipping container 10. The front corner posts 30 and 40 are some of the strongest components of the shipping container 10.

[0005] To ship a load of cargo via a shipping container, the cargo is first loaded into the interior of the shipping container, starting at the front end and moving toward the rear end. In many cases, the cargo does not completely fill the interior of the shipping container, which means that there are gaps within the load (i.e., between the cargo itself) and / or between the cargo and the walls of the shipping container. If the gaps are not minimized and the load is not secured to prevent movement, the cargo may shift during transport and collide with each other and with the interior walls of the shipping container, thereby damaging the cargo and the shipping container. Figure 1B An example load L of drums D is shown that have been loaded into a shipping container 10. Given the amount of empty space within the shipping container 10, the drums D will likely move during transport and collide with each other and the walls of the shipping container unless secured. Summary of the invention

[0006] Various embodiments of the present disclosure provide load securing devices and methods for securing a load in a shipping container. Generally, each load securing device of the present disclosure includes a base and two wings, each wing having a corner-engaging end. The wings are attached to the base and are movable relative to each other and to the base from a compact configuration in which a first distance separates the corner-engaging ends to a fixed configuration in which a second, larger distance separates the corner-engaging ends. Because the load securing device is more compact when the wings are in the compact configuration (compared to the fixed configuration), it is easier to attach to a shipping container, and particularly to a front corner post of a shipping container, than a similar load securing device having immovable wings fixed in the fixed configuration.

[0007] An operator performs the load securing method of the present disclosure to secure a load in a shipping container using at least two load securing devices. Specifically, the operator attaches separate load securing devices to two front corner posts of the shipping container. To do this, for each load securing device, the operator inserts the load securing device (with the wings in a compact configuration at this point) into a load securing device receiving channel defined (in part) by the wall of its corresponding front corner post. Next, the operator manipulates the wings into a secured configuration so that their corner engagement ends separate and engage the opposing inner corners of the front corner post. This engagement ensures that the load securing device remains in place during the remainder of the load securing method. The operator attaches a separate securing member (such as a flexible strap) to each load securing device and wraps the securing member around the load until their free ends meet. The operator attaches the free ends of the opposing securing members to each other (such as via a buckle) and tensions the securing member around the load using a tensioning tool. This pulls the load together and against the front end wall of the shipping container to secure the load, thereby completing the load securing method. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Although the systems, devices, and processes described herein can be implemented in various forms, the drawings illustrate and the specification describes certain exemplary and non-limiting embodiments. Not all of the components shown in the drawings and described in the specification may be required, and some implementations may include additional, different, or fewer components. Changes may be made in the following aspects without departing from the spirit or scope of the claims: the arrangement and type of components; the shape, size, and material of the components; and the connection of the components. Unless otherwise specified, any direction mentioned in the specification reflects the orientation of the components shown in the corresponding drawings and does not limit the scope of the present disclosure. Further, terms related to the installation process (such as installation, connection, etc.) are not intended to be limited to direct installation processes, but should be broadly interpreted to include indirect and operative installation, connection, and other installation processes. This specification is intended to be regarded as a whole and interpreted according to the principles of the present disclosure and as understood by ordinary technicians in the field.

[0032] Various embodiments of the present disclosure provide load securing devices and methods for securing a load in a shipping container. Generally, each load securing device of the present disclosure includes a base and two wings, each wing having an angle engagement end. The wings are attached to the base and are movable relative to each other and to the base from a compact configuration in which a first distance separates the angle engagement ends to a fixed configuration in which a second, larger distance separates the angle engagement ends. Because the load securing device is more compact when the wings are in the compact configuration (compared to the fixed configuration), it is easier to attach to a shipping container, and particularly to a front corner post of a shipping container, than a similar load securing device having immovable wings that are fixed in the fixed configuration.

[0033] An operator performs the load securing method of the present disclosure to secure a load in a shipping container using at least two load securing devices. Specifically, the operator attaches separate load securing devices to two front corner posts of the shipping container. To do this, for each load securing device, the operator inserts the load securing device (with the wings in a compact configuration at this point) into a load securing device receiving channel defined (in part) by the wall of its corresponding front corner post. Next, the operator manipulates the wings into a secured configuration so that their corner engagement ends separate and engage the opposing inner corners of the front corner post. This engagement ensures that the load securing device remains in place during the remainder of the load securing method. The operator attaches a separate securing member (such as a flexible strap) to each load securing device and wraps the securing member around the load until their free ends meet. The operator attaches the free ends of the opposing securing members to each other (such as via a buckle) and tensions the securing member around the load using a tensioning tool. This pulls the load together and against the front end wall of the shipping container to secure the load, thereby completing the load securing method.

[0034] Figure 2 , Figure 3 and FIG. 5A to FIG. 5E An example embodiment of a load securing device 100 of the present disclosure is shown. The load securing device 100 includes a base 110, a first wing 120 and a second wing 130, and a retaining element 116. The base 110 and the first wing 120 define a first securing member receiving opening 105a that is constrained on all sides, and the base 110 and the second wing 130 define a second securing member receiving opening 105b that is constrained on all sides.

[0035] The base 110 includes a cylindrical body 112 and a disc-shaped head 114 at one end of the body 112. The head 114 has a larger diameter than the body 112. A hole (not numbered) sized to receive a retaining element 116 is defined at least partially through the body 112 proximate an end opposite the head 114.

[0036] The first wing 120 includes a tubular first mounting element 121 defining a first hole (not labeled) therethrough, a first arm 122 extending from the first mounting element 121, a corner joint element 123 extending laterally (here vertically) from the first arm 122, a second arm 124 extending laterally (here vertically) from the corner joint element 123, and a tubular second mounting element 125 defining a hole (not labeled) therethrough that is coaxial with the first hole defined by the first mounting element 121. The corner joint element 123 represents the corner joint end of the first wing 120.

[0037] In this example embodiment, first arm 122, corner joint element 123, and second arm 124 are cylindrical, but in other embodiments, they may be tubular or take any other suitable shape. In this example embodiment, first arm 122, corner joint element 123, and second arm 124 are integrally formed, and first mounting element 121 and second mounting element 125 are welded to first arm 122 and second arm 124, respectively. In other embodiments, first mounting element 121, first arm 122, corner joint element 123, second arm 124, and second mounting element 125 may be attached to each other in any suitable manner.

[0038] The second wing 130 includes a tubular first mounting element 131 defining a first hole (not labeled) therethrough, a first arm 132 extending from the first mounting element 131, an angle joint element 133 extending laterally (here vertically) from the first arm 132, a second arm 134 extending laterally (here vertically) from the angle joint element 133, and a tubular second mounting element 135 defining a hole (not labeled) therethrough that is coaxial with the first hole defined by the first mounting element 131. The angle joint element 133 represents the angle joint end of the second wing 130.

[0039] In this example embodiment, first arm 132, corner joint element 133, and second arm 134 are cylindrical, but in other embodiments, they may be tubular or take any other suitable shape. In this example embodiment, first arm 132, corner joint element 133, and second arm 134 are integrally formed, and first mounting element 131 and second mounting element 135 are welded to first arm 132 and second arm 134, respectively. In other embodiments, first mounting element 131, first arm 132, corner joint element 133, second arm 134, and second mounting element 135 may be attached to each other in any suitable manner.

[0040] The first wing 120 and the second wing 130 are movably (in this embodiment, pivotally) attached to the base 110 so that they can freely pivot about the base 110 and relative to each other. More specifically, the body 112 of the base 110 is received in and extends through a first hole defined by a first mounting element 121 of the first wing 120, a first hole defined by a first mounting element 131 of the second wing 130, a second hole defined by a second mounting element 125 of the first wing 120, and a second hole defined by a second mounting element 135 of the second wing 130. The retaining element 116 is received in the hole defined in the body 112 of the base 110 to retain the first wing 120 and the second wing 130 on the base 110. In this embodiment, the retaining element 116 includes a pin, but in other embodiments, the retaining element may include any suitable element.

[0041] Because the first wing 120 and the second wing 130 are movably (in this embodiment, pivotably) attached to the base 110, they can pivot relative to each other about the base 110 and between a compact configuration and a fixed configuration. Figure 5A and Figure 5B In the compact configuration shown, the first wing 120 and the second wing 130 are positioned such that a first distance separates their respective angularly joined ends and such that an angle A ( Figure 5A) is a first angle less than 90 degrees. In this example embodiment, when in the compact configuration, the distance between the corner joint ends of the first wing 120 and the second wing 130 (here, the corner joint elements 123 and 133) and the angle A are minimized. FIG. 5C to FIG. 5E In the fixed configuration shown, the first wing 120 and the second wing 130 are positioned such that a second distance greater than the first distance separates their respective angular engagement ends and such that the angle A ( Figure 5C ) is a second angle that is greater than the first angle (and is approximately 90 degrees in this example embodiment).

[0042] When the first wing and the second wing are in their compact configuration, the load securing device has a compact profile that easily fits within a load securing device receiving channel defined by a front corner post of a shipping container, which facilitates installation. Another benefit provided by the movable wings is that they can adapt to differences in front corner post geometry. For example, if the front corner post is deformed or otherwise misshapen, the wings can adapt and move further outward or inward as needed to conform to the shape of this particular front corner post. If the wings were not movable, the load securing device might be too large to fit (or require significant effort to fit), or might be too small and unusable (not engaging the corner).

[0043] Figure 4A and Figure 4B A first front corner post 30 of a shipping container 10 is shown (although other front corner posts may have different geometries). First front corner post 30 includes first, second, third, fourth, fifth, and sixth corner post walls 31-36. Third corner post wall 33 and fourth corner post wall 34 are attached and oriented transversely (here, perpendicularly) to each other to form a first interior corner IC1. Second corner post wall 32 and fifth corner post wall 35 are attached to third corner post wall 33 and fourth corner post wall 34, respectively, and extend transversely (here, perpendicularly) toward each other, respectively, from the third corner post wall and fourth corner post wall, and form opposing second interior corners IC2 and third interior corners IC3, respectively. First corner post wall 31 and sixth corner post wall 36 are attached to second corner post wall 32 and fifth corner post wall 35, respectively, and extend transversely (here, perpendicularly) away from each other, respectively, from the second corner post wall and fifth corner post wall, and form first exterior corners EC1 and second exterior corners EC2, respectively. As shown in FIG. Figure 4A and Figure 4B As shown, second corner post wall 32, third corner post wall 33, fourth corner post wall 34, and fifth corner post wall 35, and a boundary plane P extending between first exterior corner EC1 and second exterior corner EC2 of first corner post 30 define a load securing device receiving channel V sized to receive a load securing device for attachment to first corner post 30. Second front corner post 40 is identical to first front corner post 30, and therefore is not separately shown or described.

[0044] FIG. 5A to FIG. 5E The load securing device 100 is shown attached to the front corner post 30 and the securing member S is attached to the load securing device 100. Figure 5A , the first wing 120 and the second wing 130 of the load securing device 100 are initially in a compact configuration. Figure 5B As shown, the operator moves the load securing device 100 within (or partially within) the load securing device receiving channel V defined by the front corner post 30 so that the base 110 is adjacent to the first interior corner IC1. Figure 5C As shown, the operator manipulates the first and second wings 120, 130 into a secured configuration by separating the respective corner engagement ends of the first and second wings until they engage the second and third interior corners IC2, IC3 of the front corner post 30. This engagement holds the load securing device 100 in place as the operator attaches the securing member S to the load securing device 100. Specifically, the operator passes one end of the securing member S through the first securing member receiving opening 105a, around the base 110 and the mounting elements 121, 125, 131, and 135 of the first and second wings 120, 130 mounted to the base 110, and back through the second securing member receiving opening 105b. In this embodiment, the securing member S comprises a woven polyester strip, but in other embodiments, the securing member may comprise any other suitable component. Figure 5D and Figure 5E A load securing device 100 is shown with a securing member S attached thereto.

[0045] As described above, to perform the load securing method and secure a load in a shipping container 10 using two load securing devices 100A and 100B, the operator first attaches the load securing devices 100A and 100B to the front corner posts 30 and 40, respectively. An advantage of the load securing devices of the present disclosure is that they can be used on either front corner post of a shipping container. That is, there will not be one type of load securing device used for the left front corner post and a different type of load securing device used for the right front corner post. This means that the operator does not have to worry about making sure they are using the correct type of load securing device for a given front corner post. As described above, the operator attaches securing members S1 and S2 to the respective load securing devices 100A and 100B, respectively. Fig. 5F The shipping container 10 is shown after the first and second load securing devices 100A, 100B have been attached to the first and second front corner posts 30, 40, respectively, and after the first and second securing members S1, S2 have been attached to the first and second load securing devices 100A, 100B, respectively (labeled but not shown).

[0046] like Figure 5GAs shown, with the securing members S1 and S2 out of the way, a load L of drums D is loaded into the interior of the shipping container 10. Figure 5H As shown, the operator manipulates the upper free ends of the first fixing member S1 and the second fixing member S2 so that they are wrapped around the load L and meet near the middle of the load L, and manipulates the lower free ends of the first fixing member S1 and the second fixing member S2 so that they are wrapped around the load L and positioned below the upper free ends. The operator attaches the upper free end and the lower free end to each other (such as via a buckle or any other suitable component), and uses a tensioning tool (such as an electrically (or other) powered belt tightener) to tighten the fixing members S1 and S2 around the load L to a specific tension. Fig.5I As shown, this draws the drums D of the load L together and against the front end wall 16 of the shipping container 10 to secure the load L. This completes the load securing method.

[0047] Figures 6 to 8 Another example embodiment of a load securing device 200 of the present disclosure is shown. The load securing device 200 includes a base 210, a first wing 220 and a second wing 230, and a first retaining element 240a and a second retaining element 240b. The base 210 and the first wing 220 define a first securing member receiving opening 205a that is constrained on all sides, and the base 210 and the second wing 230 define a second securing member receiving opening 205b that is constrained on all sides.

[0048] The base 210 includes a cylindrical body 212 that defines an annular first groove 214a near one end and an annular second groove 214b near the other end. As described below, the first groove 214a and the second groove 214b are sized to receive the first retaining element 240a and the second retaining element 240b.

[0049] The first wing 220 includes a tubular first mounting element 221 defining a first hole (not labeled) therethrough, a first arm 222 extending from the first mounting element 221, a planar corner engagement element 223 extending from the first arm 222 and including a corner engagement end surface 223a, a second arm 224 extending from the corner engagement element 223, and a tubular second mounting element 225 defining a hole (not labeled) therethrough that is coaxial with the first hole defined by the first mounting element 221. The corner engagement end surface 223a represents the corner engagement end of the first wing 220. In this example embodiment, the components of the first wing 220 are integrally formed, but in other embodiments, the components may be attached to each other in any suitable manner.

[0050] The second wing 230 includes a tubular first mounting element 231 defining a first hole (not labeled) therethrough, a first arm 232 extending from the first mounting element 231, a planar corner engagement element 233 extending from the first arm 232 and including a corner engagement end surface 233a, a second arm 234 extending from the corner engagement element 233, and a tubular second mounting element 235 defining a hole (not labeled) therethrough that is coaxial with the first hole defined by the first mounting element 231. The corner engagement end surface 233a represents the corner engagement end of the second wing 230. In this example embodiment, the components of the second wing 230 are integrally formed, but in other embodiments, the components may be attached to each other in any suitable manner.

[0051] The first wing 220 and the second wing 230 are movably (in this embodiment, pivotally) attached to the base 210 so that they can freely pivot about the base 210 and relative to each other. More specifically, the body 212 of the base 210 is received in and extends through a first hole defined by the first mounting element 221 of the first wing 220, a first hole defined by the first mounting element 231 of the second wing 230, a second hole defined by the second mounting element 225 of the first wing 220, and a second hole defined by the second mounting element 235 of the second wing 230. The first retaining element 240a and the second retaining element 240b are received in a first groove 240a and a second groove 240b defined in the body 212 of the base 210 to retain the first wing 220 and the second wing 230 on the base 210.

[0052] Because the first wing 220 and the second wing 230 are movably (in this embodiment, pivotally) attached to the base 210, they can pivot relative to each other about the base 210 and between a compact configuration and a fixed configuration. Figure 5A and Figure 5B In the illustrated compact configuration of the first wing 120 and the second wing 130 of the load securing device 100, the first wing 220 and the second wing 230 are positioned such that a first distance separates their respective corner engagement ends and such that the angle formed between the wings is a first angle that is less than 90 degrees. In this example embodiment, when in the compact configuration, the distance and angle between the corner engagement ends (here, corner engagement end surfaces 223a and 233a) of the first wing 220 and the second wing 230 are minimized. Figure 8 The fixed configuration shown (similar to FIG. 5C to FIG. 5E1 (a fixed configuration of first wing 120 and second wing 130 of load securing device 100 shown in FIG. 1 ), first wing 220 and second wing 230 are positioned such that a second distance greater than the first distance separates their respective corner engagement ends, and such that the angle between the wings is a second angle greater than the first angle (and is approximately 90 degrees in this example embodiment). When first wing 220 and second wing 230 are in their compact configuration, load securing device 200 has a compact profile that easily fits within a load securing device receiving channel defined by a front corner post of a shipping container, which facilitates installation.

[0053] The load securing device 200 is attached to the front corner post of the shipping container in a manner similar to the manner described above for attaching the load securing device 100 to the front corner post 30. After attachment, the operator may perform the remainder of the load securing method described above.

[0054] Figures 9 to 11 Another example embodiment of a load securing device 300 of the present disclosure is shown. The load securing device 300 includes: a base 310; a first wing 320, a second wing 330, a third wing 340, and a fourth wing 350; a first biasing element 360a and a second biasing element 360b; and a first retaining element 370a and a second retaining element 370b. The base 310, the first wing 320, and the third wing 330 define a first securing member receiving opening 305a that is open on one side, and the base 310, the second wing 330, and the fourth wing 350 define a second securing member receiving opening 305b that is open on one side.

[0055] The base 310 includes a body having a cylindrical central body portion 312 and cylindrical first and second mounting body portions 314, 316 extending from opposite ends of the central body portion 312. The diameters of the first and second mounting body portions 314, 316 are smaller than the diameters of the central body portion 312. The first and second mounting body portions 314, 316 define annular first and second grooves 314a, 316a, respectively, near their ends opposite the central body portion 312. The first and second grooves 314a, 314b are sized to receive the first and second retaining elements 370a, 370b, as described below.

[0056] The first wing 320 includes a body 322 having a mounting end 322a defining a hole (not labeled) therethrough and an opposite corner engagement end 322b. The second wing 330 includes a body 332 having a mounting end 332a defining a hole (not labeled) therethrough and an opposite corner engagement end 332b. The third wing 340 includes a body 342 having a mounting end 342a defining a hole (not labeled) therethrough and an opposite corner engagement end 342b. The fourth wing 350 includes a body 352 having a mounting end 352a defining a hole (not labeled) therethrough and an opposite corner engagement end 352b.

[0057] The first, second, third and fourth wings 320 to 350 are movably (in this embodiment, pivotally) attached to the base 310 so that they can pivot independently about the base 310 and relative to each other. More specifically, the first body mounting portion 314 of the base 310 is received in the holes defined by the mounting ends 322a and 332a of the bodies 322 and 332 of the first and second wings 320 and 330, and extends through these holes. The first retaining element 370a is received in the groove 314a defined in the first body mounting portion 314 of the base 310 to retain the first and second wings 320 and 330 on the base 310. The second body mounting portion 316 of the base 310 is received in the holes defined by the mounting ends 342a and 352a of the bodies 342 and 352 of the third and fourth wings 340 and 350, and extends through these holes. The second retaining element 370 b is received in the groove 316 a defined in the second body mounting portion 316 of the base 310 to retain the third wing 340 and the fourth wing 350 on the base 310 .

[0058] Because the first wing 320 and the second wing 330 are movably (in this embodiment, pivotally) attached to the base 310, they can pivot relative to each other about the base 310 and between a compact configuration and a fixed configuration. Similarly, the third wing 340 and the fourth wing 350 can pivot relative to each other about the base 310 and between a compact configuration and a fixed configuration. In the compact configuration (similar to Figure 5A and Figure 5B In the illustrated compact configuration of first wing 120 and second wing 130 of load securing device 100, first wing 320 and second wing 330 and third wing 340 and fourth wing 350 are positioned such that a first distance separates their respective corner joint ends and such that the angle formed between the wings is a first angle that is less than 90 degrees. In this example embodiment, the distances and angles between the corner joint ends of the wings are minimized when in the compact configuration. Fig. 9 The fixed configuration shown (similar to FIG. 5C to FIG. 5E1 (a fixed configuration of the first wing 120 and the second wing 130 of the load securing device 100 shown in FIG. 1 ), the first wing 320 and the second wing 330 and the third wing 340 and the fourth wing 350 are positioned such that a second distance greater than the first distance separates their respective corner engagement ends and such that the angle between the wings is a second angle greater than the first angle (and is approximately 90 degrees in this example embodiment). When the first wing 320 and the second wing 330 and the third wing 340 and the fourth wing 350 are in their compact configuration, the load securing device 300 has a compact profile that easily fits within a load securing device receiving channel defined by a front corner post of a shipping container, which facilitates installation.

[0059] The first biasing element 360a is operably coupled to the first wing 320 and the second wing 330 to bias the first wing 320 and the second wing 330 to a fixed configuration. In this example embodiment, the first biasing element 360a includes a torsion spring having two arms (not labeled) received in holes (not labeled) defined in the first arm 320 and the second arm 330, and having a head mounted to the first body mounting portion 314 of the base 310. Similarly, the second biasing element 360b is operably coupled to the third wing 340 and the fourth wing 350 to bias the third wing 340 and the fourth wing 350 to a fixed configuration. In this example embodiment, the second biasing element 360b includes a torsion spring having two arms (not labeled) received in holes (not labeled) defined in the third arm 340 and the fourth arm 350, and having a head mounted to the second body mounting portion 316 of the base 310. In other embodiments, the biasing element may be any other type of spring or any other suitable biasing element.

[0060] Load securing device 300 is attached to the front corner post of the shipping container in a manner similar to the manner in which load securing device 100 is attached to the front corner post 30 described above. The difference is that before inserting the load securing device into the load securing device receiving channel, the operator manipulates the wings into the compact configuration by overcoming the biasing force of the biasing element. After attachment, the operator can perform the remainder of the load securing method described above.

[0061] Other embodiments of load securing devices of the present disclosure, such as load securing devices 100 and 200 , may include one or more biasing elements operably engaged to the first wing and the second wing to bias the first wing and the second wing into their secured configurations.

[0062] In the above and in Figure 2 , Figure 3 and FIG. 5A to FIG. 11In the embodiment of the load securing device shown in FIG. 1 , the wings of the load securing device are sized so that when in a secured position and attached to a front corner post of a shipping container, the wings are transverse (and in some embodiments, perpendicular) to each other. The angle defined between the wings can be, for example, between about 90 degrees and about 180 degrees. In other embodiments, the wings of the load securing device are sized so that when in a secured position, the wings are parallel and generally coplanar (and in some embodiments, parallel to) each other. Figure 4A and Figure 4B Plane P as shown). In some embodiments, the load securing device includes a stop (e.g., on a wing or base) that engages the wing when the wing reaches the secured position and prevents the wing from pivoting beyond the secured position. In other words, in these embodiments, the wings can pivot so that the maximum angle formed between them is this particular angle. This prevents excessive pivoting of the wings, which could result in loss of engagement between the wings and the interior corner of the front corner post and removal of the load securing device from the front corner post.

[0063] Figures 12 to 14E Another example embodiment of a load securing device 400 of the present disclosure is shown. The load securing device 400 includes a base 410 and a first wing 420 and a second wing 430. The base 410 and the first wing 420 and the second wing 430 define a first securing member receiving opening 405a and a second securing member receiving opening 405b on opposite sides of the base 410. These securing member receiving openings are each open on one side.

[0064] The base 410 includes a generally cylindrical body 412. A tool contact element 412a is formed in the center of the body 412 and includes one or more generally planar surfaces that can be engaged by a tool to cause the body 412 to rotate relative to the first wing 420 and the second wing 430 (as described below). A first end 412b of the body 412 has left-hand threads formed thereon, and a second end 412c of the body 412 opposite the first end 412b has right-hand threads formed thereon (although in other embodiments, the directions of the threads are reversed).

[0065] The first wing 420 includes a body 422 having a mounting end 422a and an opposite corner engagement end 422b. A left-handed threaded mounting hole 422c is formed in the body 422 and extends partially through the body 422 from the mounting end 422a toward the corner engagement end 422b. Similarly, the second wing 430 includes a body 432 having a mounting end 432a and an opposite corner engagement end 432b. A right-handed threaded mounting hole 432c is formed in the body 432 and extends partially through the body 432 from the mounting end 432a toward the corner engagement end 432b.

[0066] The first wing 420 and the second wing 430 are movably attached to the base 410 so that they can translate relative to the base 410 and relative to each other. More specifically, the first end 412b of the body 412 of the base 410 is threadedly received in a threaded hole 422c formed in the body 422 of the first wing 420, and the second end 412c of the body 412 of the base 410 is threadedly received in a threaded hole 432c formed in the body 432 of the second wing 430. Because the ends of the base 410 have opposite threads, relative rotation between the base 410 and the first wing 420 and / or the second wing 430 causes the first wing 420 and the second wing 430 to move toward or away from each other depending on the direction of rotation. For example, when the base 410 is rotated in the direction R1 ( Fig.12 ) relative to the first wing 420 and the second wing 430, the first wing 420 and the second wing 430 move away from each other. Fig.12 ) is rotated relative to the first wing 420 and the second wing 430, the first wing 420 and the second wing 430 move toward each other.

[0067] Because the first wing 420 and the second wing 430 are movably attached to the base 410, they can move relative to the base and relative to each other between a compact configuration and a fixed configuration. Figures 12 to 14B In the compact configuration shown, the first wing 420 and the second wing 430 are positioned such that a first distance separates their respective corner engagement ends 422b and 432b. In this example embodiment, when in the compact configuration, the first end 412b and the second end 412c of the body 412 of the base 410 are fully threaded into the respective threaded holes 422c and 432c formed in the first wing 420 and the second wing 430 so that the distance between the respective corner engagement ends 422b and 432b of the first wing and the second wing is minimized. FIG. 14C to FIG. 14E In the fixed configuration shown, first wing 420 and second wing 430 are positioned such that a second distance, which is greater than the first distance, separates their respective corner engagement ends 422b and 432b. When first wing 420 and second wing 430 are in their compact configurations, load securing device 400 has a compact profile that easily fits within a load securing device receiving channel defined by a front corner post of a shipping container, which facilitates installation. In this example embodiment, the angle (not labeled) formed between the wings does not substantially change (and is approximately 180 degrees in this example embodiment) as the wings move between their compact and fixed configurations.

[0068] FIG. 14A to FIG. 14E The load securing device 400 is shown attached to the front corner post 30 and the securing member S is attached to the load securing device 400. Fig.14A , the first wing 420 and the second wing 430 of the load securing device 400 are initially in a compact configuration. Fig. 14B As shown, the operator moves the load securing device 400 within (or partially within) the load securing device receiving channel V defined by the front corner post 30 so that the corner engaging ends 422b and 432b of the wings 420 and 430 are generally aligned with the second interior corner IC2 and the third interior corner IC3 of the front corner post 30. Fig. 14C As shown, the operator moves in direction R1 ( Fig.12 ), which causes the first wing 420 and the second wing 430 to separate until their respective corner engagement ends 422b and 432b engage the second interior corner IC2 and the third interior corner IC3 of the front corner post 30. This engagement holds the load securing device 400 in place as the operator attaches the securing member S to the load securing device 400. Specifically, the operator passes one end of the securing member S through the first securing member receiving opening 405a, around the base 410, and back through the second securing member receiving opening 405b. After attachment, the operator can perform the remainder of the load securing method described above.

[0069] Although the corner engagement ends 422b and 432b are formed as points in this example embodiment (as shown), they may take any suitable shape, such as a flat shape, a curved shape, an inverted V-shape, a U-shape, or the like.

[0070] In other embodiments, a tool contact element formed on the center of the body of the base of the load fixture defines a full or partial hole sized to receive a tool, such as a screwdriver. The hole enables an operator to use the tool to rotate the base by inserting the tool into the hole and then rotating the tool.

[0071] Figures 15 to 18 Another example embodiment of a load securing device 500 of the present disclosure is shown. The load securing device 500 includes a base 510, a first wing 520 and a second wing 530, a first spacer 550 and a second spacer 560, a first biasing element 570a and a second biasing element 570b, and a first anti-retraction assembly 580 and a second anti-retraction assembly 590. The base 510, the first wing 520, and the first spacer 550 and the second spacer 560 define a first securing member receiving opening 505a that is constrained on all sides, and the base 510, the second wing 530, and the first spacer 550 and the second spacer 560 define a second securing member receiving opening 505b that is constrained on all sides.

[0072] The base 510 includes a generally cylindrical body 512. First and second holes (not labeled) sized to receive first and second spacers 550, 560, respectively, are defined through the body 512 proximate opposite ends of the body 512. The longitudinal axes of the holes are oriented transversely (here, perpendicularly) to the longitudinal axis of the body 512.

[0073] The first wing 520 includes a body 522 having a mounting end 522a and an opposite corner engagement end 522b. A first spacer receiving hole 522c is formed in the body 522 and extends partially through the body 522 from the mounting end 522a toward the corner engagement end 522b, thereby terminating at a first end surface 522e. A second spacer receiving hole 522d is formed in the body 522 and extends partially through the body 522 from the mounting end 522a toward the corner engagement end 522b, thereby terminating at a second end surface 522f.

[0074] The second wing 530 includes a body 532 having a mounting end 532a and an opposite corner engagement end 532b. A first spacer receiving hole 532c is formed in the body 532 and extends partially through the body 532 from the mounting end 532a toward the corner engagement end 532b, thereby terminating at a first end surface 532e. A second spacer receiving hole 532d is formed in the body 532 and extends partially through the body 532 from the mounting end 532a toward the corner engagement end 532b, thereby terminating at a second end surface 532f.

[0075] The first spacer 550 includes a tubular body 552 having a sawtooth profile defined along a portion of its length. Fig.17 As best shown, the sawtooth profile includes a repeating pattern of vertical stop surfaces 552a and inclined ramp surfaces 552b. As described below, the sawtooth profile is engaged by anti-retraction assemblies 580 and 590 to provide an anti-retraction function. The second spacer 560 includes a generally tubular body 562.

[0076] The first wing 520 and the second wing 530 are movably attached to the base 510 so that they can translate relative to the base and relative to each other (subject to the anti-retraction function explained below). More specifically, the first spacer 550 is slidably received in and extends through the first hole of the body 512 of the base 510 so that one of its ends is slidably received in the first spacer receiving hole 522c of the body 522 of the first wing 520, and its opposite end is slidably received in the first spacer receiving hole 532c of the body 532 of the second wing 530. The second spacer 560 is slidably received in and extends through the second hole of the body 512 of the base 510 so that one of its ends is slidably received in the second spacer receiving hole 522d of the body 522 of the first wing 520, and its opposite end is slidably received in the second spacer receiving hole 532d of the body 532 of the second wing 530.

[0077] Because the first wing 520 and the second wing 530 are movably attached to the base 510 (via the first spacer 550 and the second spacer 560), they can move relative to the base 510 and relative to each other between a compact configuration and a fixed configuration. In the compact configuration, the first wing 520 and the second wing 530 are positioned such that a first distance separates their respective corner joint ends 522b and 532b. In this example embodiment, in the compact configuration, the first wing 520 and the second wing 530 are positioned adjacent to (and in some embodiments, contacting) the base 510 such that the distance between the respective corner joint ends 522b and 532b of the first wing and the second wing is minimized. Fig.15 , Fig.16 and Fig.18 In the secured configuration shown, first wing 520 and second wing 530 are positioned such that a second distance greater than the first distance separates their respective corner engagement ends 522b and 532b. When first wing 520 and second wing 530 are in their compact configurations, load securing device 500 has a compact profile that easily fits within a load securing device receiving channel defined by a front corner post of a shipping container, which facilitates installation.

[0078] The first biasing member 570a, which includes a compression spring in this example embodiment, is slidably received in a hole defined through the first spacer 550, and the first biasing member is sized to contact and extend between the first end surface 522e of the body 522 of the first wing 520 and the first end surface 532e of the body 532 of the second wing 530. The second biasing member 570b, which includes a compression spring in this example embodiment, is slidably received in a hole defined through the second spacer 560, and the second biasing member is sized to contact and extend between the second end surface 522f of the body 522 of the first wing 520 and the second end surface 532f of the body 532 of the second wing 530. Thus, the first biasing member and the second biasing member are operably engaged to the first wing 520 and the second wing 530, and are configured to bias the first wing 520 and the second wing 530 to a fixed configuration. In other embodiments, the biasing element may be any other type of spring or any other suitable biasing element.

[0079] The first anti-retraction component 580 and the second anti-retraction component 590 are operably connected to the first wing 520 and the second wing 530, respectively, and are operably connected to the first spacer 550, and prevent the first wing and the second wing from moving toward the base 510. Fig.17 As best shown, the second anti-retraction assembly 590 includes a wedge-shaped head 592 and a biasing element 594 (here a compression spring). The second anti-retraction assembly 590 is received in a partial hole (not labeled) defined in the body 532 of the second wing 530, which is transverse to and intersects the first spacer receiving hole 532c. The biasing element 594 is operably connected to the head 592 to bias the head 592 into contact with the surface of the first spacer 550 on which the sawtooth profile is defined. The head 592 is shaped and oriented to: (1) engage the vertical stop surface 552a when a force is applied to the second wing 530 in a direction toward the base 510, which prevents the second wing 530 from moving toward the base 510; and (2) travel along the continuous ramp surface 552b when a force is applied to the second wing 530 in a direction away from the base 510, which does not prevent the second wing 530 from moving away from the base 510. Although not shown in detail, the first anti-retraction component 580 provides similar functionality for the first wing 520. This is merely one example anti-retraction component, and any other suitable component may be used to achieve similar functionality.

[0080] The load securing device 500 is attached to the front corner post of the shipping container in a manner similar to the manner in which the load securing device 100 is attached to the front corner post 30 described above. Because the first biasing element 570a and the second biasing element 570b bias the first wing 520 and the second wing 530 to the fixed configuration, and the anti-retraction components 580 and 590 prevent the first wing 520 and the second wing 530 from moving toward the base 510, the load securing device 500 is delivered to the operator with the first wing 520 and the second wing 530 temporarily secured in a compact configuration. For example, the first wing 520 and the second wing 530 can be tied together (e.g., via a zip tie, a rubber band, or the like), which prevents the wings from moving. Once the operator positions the load securing device 500 within the load securing device receiving channel of the front corner post, the operator releases the first wing 520 and the second wing 530 (e.g., by cutting the zip tie). The first biasing element 570a and the second biasing element 570b bias the first wing 520 and the second wing 530 to a fixed configuration and engage the inner corner of the front corner post. Once they reach this position, the anti-retraction components 580 and 590 prevent the first wing 520 and the second wing 530 from moving back toward the base 510, effectively locking them in place. After attachment, the operator can perform the remainder of the load securing method described above.

[0081] In other embodiments, the load securing device does not include an anti-retraction assembly. In some embodiments, the anti-retraction assembly is releasable to enable the corresponding wing to move toward the base. This enables an operator to remove the load securing device from the front corner post by releasing one of the anti-retraction assemblies, which enables the operator to move the corresponding wing toward the base and out of engagement with the inner corner of the front corner post.

[0082] In other embodiments, the load securing device includes a wing and a base movably attached to the wing. In these embodiments, the end of the base opposite the wing represents the corner joint end of the base. Because the wing is movably attached to the base, the wing can be moved relative to the base between a compact configuration and a fixed configuration. In the compact configuration, the wing is positioned relative to the base so that a first distance separates its respective corner joint ends. In the fixed configuration, the wing and the base are positioned so that a second distance greater than the first distance separates their respective corner joint ends.

[0083] In some embodiments, the corner engagement end of the load securing device includes a roughened surface, coating or friction enhancing element, such as a friction engagement pad, having a coefficient of friction higher than the coefficient of friction of the material forming the wing. This increased coefficient of friction enhances the frictional engagement between the corner engagement end and the front corner post.
