Description
Background of the Invention
1. Field of the Invention
The present invention relates to a load securing system, and more importantly, pertains to a load securing system for securing cargo, such as cargo on a pallet, in a trailer such as a semi or a van.
2. Description of the Prior Art
Prior art devices have not provided for adjustability, and have not distributed the focal point of the load securing device across the goods to be secured, such as boxes or pallets.
The prior art load securing devices, or better known as cargo securing devices, have utilized a strap or a single small-sized foot, such as a molded rubber foot or a bar. These have not distributed the forces of the cargo securing devices across the box or boxes.
The present invention overcomes the disadvantages of the prior art by providing an H-bar plate or plates configuration for distributing the load securing system over a wide surface area of cargo in a trailer or in a van.
Summary of the Invention
The general purpose of the present invention is a load securing system, including the use of a longitudinal member with an adjustable friction jack at one end and an H-bar and plate assembly on the other end pivotally mounted to the other end of the longitudinal member. The H-bar and plate can be centered with a longitudinal extension arm. In the alternative, more than one H-bar and plate assembly can be utilized along the length of the longitudinal member and between the friction jack and the foot plate with an extension member.
According to one embodiment of the present invention there is provided a load securing system utilizing a longitudinal member, a friction jack on a threaded rod at one end, and an H-bar and plate pivotally mounted in opposing longitudinal slots of the longitudinal member at the other end. An alternative embodiment includes positioning the H-bars with at least one plate at about the center of the longitudinal member, or using more than one H-bars and plate along the length of the longitudinal member.
Significant aspects and features of the present invention include a load securing system which is adjustable and can be utilized to secure a load at the side of a trailer. Two systems can be used to secure a load at the nose of a trailer. Systems can be utilized to secure an load midway in the trailer.
Another significant aspect and feature of the present invention is a load securing system which is easily operable and readily adjustable for any variation in the size of the pallets, the size of the load, or the width of the trailer or van.
Still another significant aspect and feature of the present invention is a load securing system which is manufactured of readily available components and is structurally stable.
Having thus described the embodiments of the present invention, it is a principal object hereof to provide a load securing system utilizing a friction jack at one end and H-bars and plate at the other end.
One object of the present invention is a load securing system intended for use in large trailers for positioning of single loads either to the side of the trailer or the nose of the trailer, singling out a single load, or positioning two loads side-by-side from falling backwards in a trailer. A load is for example and by way of illustration boxes on a pallet.
Another object of the present invention is a load securing system with H-bars and plate which distributes the load securing system over a wide surface area which is advantageous compared to the prior art which secured a load at a single point such as by ropes or straps.

Description of the Preferred Embodiments
FIG. 1 illustrates a perspective view of the load securing system 10, including a longitudinal member 12, a hollow threaded member 14 secured to one end of the longitudinal member 12, and two opposing elongated holes 16 and 18 at the other end of the longitudinal member 12. A friction jack 20 threads onto the hollow threaded member 14, and includes a handle 22 and a rubber foot plate 24 including a socket 26 positioned on a ball joint 28 secured to a rod 30 in the friction jack 20. The rod 30 extends through the hollow threaded member 14. Two opposing bars 32 and 34 are secured to a plate 36 such as by welding or the like. Two opposing tabs 38 and 40 with opposing tab holes 42 and 44 are secured to one side of the plate 36. A bolt 46 with nut 48 secures through the opposing tab holes 42 and 44 and through the opposing elongated holes 16 and 18 for alignment as illustrated in FIG. 2.
FIG. 2 illustrates a side view of the load securing system 10 where all numerals correspond to those elements previously described. Attention is drawn to placement of the bars and the plate forming an "H" configuration.
