Abstract
Description
- This application claims priority to U.S. Provisional Application No. 62/456,381, filed on Feb. 8, 2017, now pending, the disclosure of which is incorporated herein by reference.
- The disclosure relates to accessories for dunnages for protection and easier transport therof.
- In order to facilitate transport, large quantities of items are bundled together for shipment. For example, individual pieces of lumber are arranged side by side and stacked to form a substantially rectangular prism shaped collection. Transverse members (usually lengths of wood), called dunnage, are placed underneath the collection of lumber, longitudinally spaced from one another, and banding is used to secure the lumber and dunnage together. Each band wraps over the lumber and underneath a piece of dunnage.
- The bundle is configured to be lifted by a fork lift by approaching the long side of the bundle and inserting the forks between the transverse members. However, the bundles are often too wide to be loaded on to a container by lifting from the long side. Instead, the forks must engage the shorter side of the bundle. Since the dunnage lies on the ground, the forks cannot lift underneath. Instead, the operator may simply use the forks to push the near-side dunnage to slide the bundle across the ground on both the near-side and far-side dunnage, or slightly lift the end of the bundle to lift the near-side dunnage and the bundle will slide across the ground on only the far-side dunnage.
- Sliding the bundle across the ground provides various disadvantages. For example, the friction between the dunnage and the ground may make the bundle more difficult to move. A bundle of lumber may have a weight between 100 lbs. and 8,000 lbs., which can result in a very large amount of friction. Obstructions on the ground may cause the dunnage to shift, which may cause the banding to fall off or break, due to abrasion, heat generated by friction, etc. Any breaking or movement of the banding or dunnage may jeopardize the safety of the items being shipped.
- The present disclosure provides a dunnage accessory for shipping bundles to reduce the friction between the bundle and the ground and to protect the banding during transport.
- The accessory of the present disclosure may comprise a base and a pair of arms extending from the base. A receptacle may be defined on three sides by the base and pair of arms. The receptacle may be configured to receive a portion of the dunnage.
- The pair of arms may include hooks configured to retain the portion of the dunnage within the receptacle. The hooks may comprise a swept face and a sharp face. The swept face and the sharp face may meet to form a retaining edge. The retaining edges may engage the portion of the dunnage to retain said portion within the receptacle. The swept edge may guide the dunnage into the receptacle. The sharp edge may discourage removal of the dunnage from the receptacle.
- The pair of arms may further include voids to reduce the amount of material needed for manufacture the accessory.
- The accessory may be made of a resilient material, in order to widen to receive the portion of the dunnage, and pinch to retain said portion within the receptacle.
- The accessory may reduce the friction between the dunnage and the ground to allow easier transport. The accessory may further protect the dunnage and banding from damage from sliding on the ground.
- For a fuller understanding of the nature and objects of the disclosure, reference should be made to the following detailed description taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 . is a perspective view of a dunnage accessory according to an embodiment of the present disclosure; -
FIG. 2 is a detail view of part B circled inFIG. 1 ; -
FIG. 3A is a front elevation view of a skid accessory according to an embodiment of the present disclosure; -
FIG. 3B is a right side elevation view of a skid accessory according to an embodiment of the present disclosure; and -
FIG. 4 illustrates an accessory according to an embodiment of the present disclosure in which the receptacle has received a portion of a dunnage. -
FIG. 1 illustrates anaccessory 1 for dunnage according to an embodiment of the present disclosure. Theaccessory 1 may comprise abase 5 and a pair ofarms 10 extending from thebase 5. The pair ofarms 10 may be integrally formed with thebase 5. Alternatively, thearms 10 may be formed separately from thebase 5 and later attached to thebase 5.FIG. 1 depicts an embodiment where thearms 10 are integrally formed with thebase 5. When viewed collectively, thearms 10 may form a tapered shape such that a distance between a top end of eacharm 10 is (L1 inFIG. 3A ) is greater than a distance between a bottom end of each arm 10 (i.e., the length of thebase 5—L2 inFIG. 3A ) - In an exemplary embodiment of the present disclosure found to be useful with dunnage currently in use, the
base 5 may be rectangular in shape. The length L2 of thebase 5 may be 2.62 inches, the thickness T1 of thebase 5 may be 0.38 inches, and the width W of thebase 5 may be 0.88 inches (seeFIGS. 3A and 3B ). The dimensions of thebase 5 may depend on the type and dimensions of the skid used, the type and dimensions of the items arranged on the skid, and the environment where the skid is to be used. - In a specific embodiment of the present disclosure, each
arm 10 may be triangular in shape when viewed from the front of the accessory 1 (seeFIG. 3A ). Thetriangular arms 10 may be, for example, 45 degree right triangles, with a side length H of 1.75 inches. Other configurations will be apparent and make up embodiments of the present disclosure. The dimensions of thearms 10 may depend on the type and dimensions of the dunnage used, the type and dimensions of the items arranged on the dunnage, and the environment where the dunnage is to be used. - The
accessory 1 may be substantially trapezoidal in shape when viewed from the front. For example, thebase 5 may be rectangular and thearms 10 may be triangular to form a substantiallytrapezoidal accessory 1. Theaccessory 1 may have other shapes. For example, theaccessory 1 may have a shape that is generally rectilinear, semi-circular, etc. - In a specific embodiment of the present disclosure, the
accessory 1 may have an overall length L1 of 6.22 inches, an overall height H of 1.75 inches, and an overall width W of 0.88 inches (SeeFIGS. 3A-3B ). The overall dimensions of theaccessory 1 may depend on the type and dimensions of the dunnage used, the type and dimensions of the items arranged on the dunnage, and the environment where the dunnage is to be used. - The
accessory 1 may include areceptacle 15. Thereceptacle 15 may be defined on three sides by thebase 5 andarms 10. Thereceptacle 15 may be configured to receive a portion of dunnage. For example, the dunnage may be a transverse piece of wood (transverse with respect to the longitudinal arrangement of lumber in a bundle), and a portion of the this piece of wood may be received within thereceptacle 15. For example, the length L2 of thereceptacle 15 may be 2.62 inches and the depth D of thereceptacle 15 may be 1.37 inches (SeeFIG. 3A ). Thereceptacle 15 may be substantially rectangular in shape, in order to receive a substantially rectangular portion of the dunnage. The shape and dimensions of thereceptacle 15 may depend on the type and dimensions of dunnage used as will be apparent to one having skill in the art. - The
arms 10 may include hooks 20. Thehooks 20 may be configured to retain the portion of dunnage within thereceptacle 15. For example, thehooks 20 may be configured to retain a transverse member of dunnage within thereceptacle 15. Thehooks 20 may define a length L3 therebetween that is slightly smaller than the width of the dunnage received within thereceptacle 15. Theaccessory 1 will pinch the transverse member with thehooks 20 to retain the transverse member within thereceptacle 15. For example, the length L3 between thehooks 20 may be 2.32 inches. - Referring to
FIG. 2 , thehooks 20 may include a sweptface 21 and asharp face 22. The sweptface 21 may be angled from a side of thereceptacle 15. Thesharp face 22 may be perpendicular to a side of thereceptacle 15. The sweptface 21 and thesharp face 22 may meet to form a retaining edge 23. Thehooks 20 may pinch the portion of the dunnage using the retaining edges 23. The swept faces 21 of thehooks 20 may face out of thereceptacle 15 and the sharp faces 22 may face into thereceptacle 15. By this configuration, the swept faces 21 may encourage receiving a portion of dunnage within thereceptacle 15, while the sharp faces 22 may discourage removal of the portion of the dunnage from thereceptacle 15. - The
accessory 1 may be made of a material that displays resilient properties. Such properties may allow thereceptacle 15 to widen slightly to receive a transverse member of dunnage and pinch to retain the member within. For example, theaccessory 1 may be made of a plastic such as, for example, nylon, polyethylene, etc. Theaccessory 1 may be made from more than one material, including composite materials. - The
arms 10 may further include voids 25. Thevoids 25 may have substantially the same shape as thearms 10. In the specific embodiment shown inFIG. 1 , thearms 10 are triangular in shape, and thevoids 25 are also triangular in shape. Thevoids 25 may further define a thickness T2 for the sides of thearms 10. For example, the thickness T2 may be 0.21 inches (SeeFIG. 3A ). Thevoids 25 may reduce the amount of material needed for manufacturing theaccessory 1, thereby reducing the cost to manufacture theaccessory 1. - The
accessory 1 may be manufactured by additive or subtractive processes. For example, theaccessory 1 may be injection molded, extruded, 3-D printed, CNC milled, etc. The manufacturing process used to make theaccessory 1 may depend on the material(s) theaccessory 1 is composed of, and the dimensions of theaccessory 1. -
FIG. 4 illustrates anaccessory 1 according to an embodiment of the present disclosure in which thereceptacle 15 has receiveddunnage 30 of abundle 35. Bundled items 40 (e.g., lumber) may be held to thedunnage 30 via banding 45. The banding 45 may wrap around theitems 40 and under thedunnage 30. The banding 45 may reside in agroove 31 of thedunnage 30. Theaccessory 1 may receive thedunnage 30 and the banding 45 in the receptacle (i.e., a portion of the length ofdunnage 30—where length is into the page inFIG. 4 ). As such, theaccessory 1 may protect the banding 45 from contact with the ground. - The
accessory 1 may be made of a material that has a lower coefficient of friction with the ground than thedunnage 30. As such, theaccessory 1 may reduce the friction between thebundle 35 and the ground, and make thebundle 35 easier to transport. - One, two, or
more accessories 1 may be arranged on a length ofdunnage 30, for example,multiple accessories 1 may be distributed along the length ofdunnage 30. In this matter, the accessories may improve the balance of weight in the transverse direction for easier transport. In some embodiments, it is advantageous to arrange multiple accessories such that only theaccessories 1 are in contact with the ground, so friction may be reduced. Further, obstructions on the ground will be less likely to effect the position of thedunnage 30 since only theaccessories 1 are in contact with the ground. If the one end of thebundle 35 is lifted when pushed onto a container,accessories 1 can be arranged on thedunnage 30 at the opposite end of thebundle 35. - In an exemplary embodiment, a
bundle 35 includingdunnage 30 may include a pair ofaccessories 1 arranged to receive each piece ofdunnage 30. Accordingly, if thebundle 35 is simply pushed on to a container, theaccessories 1 arranged on thedunnage 30 will be in contact with the ground. - The accessory of the present disclosure may provide certain advantages for transporting bundles of lumber. First, the accessory may reduce the friction between the bundle and the ground, which may make the bundle easier to move. Second, the accessory may protect the banding, which may reduce the chance of the banding breaking and causing damage to the bundled items. Third, the accessory may reduce the chance of obstructions or frictional forces effecting the position of the dunnage.
- Although the present disclosure has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present disclosure may be made without departing from the spirit and scope of the present disclosure.
