Abstract

An apparatus is disclosed for protecting the edges of cargo and freight from damage caused by contact with tie downs, cable, chains and/or straps used to secure the cargo or freight from shifting during transport. The disclosed invention helps eliminate slippage, dishing and abrasion of cargo caused by traditional devices used in the securement.

Description

FIELD OF THE INVENTION

This invention relates to cargo securement devices, and more particularly relates to an apparatus for protecting the edges of cargo and freight from wear caused by chains, straps and tie downs.

DESCRIPTION OF THE RELATED ART

The edges of cargo and freight are often damaged during transport through contact with tie downs, chains or straps used to secure the cargo. Straps and chains can slip across the surface of cargo; causing abrasion, cracking, and dishing of the cargo.
Many types of cargo and freight are transported long distances via sea, air, truck, and the like. During transport, the very devices used to secure and protect cargo, such as straps and chains, can damage the cargo, resulting in unnecessary insurance claims, unnecessary wear to straps, and product losses.
Edge guards are known in the industry, which consist of rigid, angularly shaped objects that trace the edges of regularly shaped containers and freight packaging when overlaid on them, and provide a buffer between securement straps and the cargo secured, reducing wear to the cargo. These edge guards are commonly called edge protectors or veeboards (because of the v-shaped angle of the cargo they are designed to protect).
Cargo and freight containers, however, are not always regularly shaped. Their edges are not always uniform; and there are not edge protectors in the prior art that can be adjusted to effectively protect the edges of a variety of irregularly shaped cargo.
Shipping organizations often are compelled to keep a large variety of edge guards of different shapes and sizes on hand to meet their needs, rather than a single type of guard protector.

SUMMARY OF THE INVENTION

From the foregoing discussion, it should be apparent that a need exists for an edge guard that can be adjusted to protect a variety of cargo edges and surfaces. Beneficially, such an apparatus would overcome many of the difficulties with prior art by providing a means for humans to adjust the edge protector quickly and a means of reducing the number of edge protectors needed to be kept by on hand by shipping companies.
The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available information management systems. Accordingly, the present invention has been developed to provide an adjustable edge guard for securing cargo, the adjustable edge guard comprising a flexible sleeve which comprises a first socket of a volume and shape to receive a first board, a second socket of a volume and shape to receive a second board, and an intermediate nylon member connecting, and affixed to, the first socket and the second socket, which intermediate nylon member spaces apart the first socket and second socket.
The adjustable edge guard further comprises a first board jacketed within, and permanently affixed within, the first socket; and a second board jacketed within, and permanently affixed within, the second socket.
In other embodiments of the adjustable edge guard, the first board and second board are flexible to trace uneven cargo surface edges. In further embodiments, the flexible sleeve is inflatable.
The first board and second board may be telescopic such that they can be telescopically adjusted to overlay varying lengths of cargo surfaces. The first board and second board may be removable and replaceable.
In still further embodiments, the first board and second board may be cylindrical in shape. The adjustable edge may comprise a plurality of flexible sleeves, each jacketing a portion of the first board and jacketing a portion of the second board.
The adjustable edge may further comprise one or more layers of padding overlaying a portion of one or more of the first socket and the second socket.
In still further embodiments, the present invention discloses an adjustable edge guard for securing cargo, the adjustable edge guard comprising: a plurality of elastomeric bands; a first board permanently affixed to the plurality of elastomeric bands and gripped within the plurality of elastomeric bands; and a second board permanently affixed to the plurality of elastomeric bands and gripped within the plurality of elastomeric bands.
These features and advantages of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

In some embodiments of the present invention, the boards 102 a-b may be cylindrical in shape rather than rectangular or cubic in shape. In other embodiments, they boards 102 a-b are flexible, so as to trace the edges of irregularly shaped cargo.
The nylon sleeves 104 a-b each comprise two sockets with a volume and shape to receive the boards 102 a-b. The two sockets of each nylon sleeve 104 jacket the boards 102 a-b. In some embodiments, the boards 102 a-b are insertably gripped by the sockets and removable. In other embodiments, the sockets of the nylon sleeves 104 a-b are permanently affixed to the boards 102 a-b using glues, staples, nails, or through other means well-known to those of skill in the art. In some embodiments, the nylon sleeves 104 a-b are stretchable.
The nylon sleeves 104 a-b may comprise any durable and flexible material, including spandex, elastomer, nylon, cotton, denim, and the like.
An intermediary nylon strap 154 (described further in relation to FIG. 1B) interconnects the nylon sockets of each of nylon sleeves 104 a-b and is affixed to both.
