Description
Background of the Invention
1. Field of the Invention
This invention relates to tie-downs, and more particularly to a system and method for securing articles to a load bearing structure during storage or transportation.
2. Previous Art
Historically, teamsters have used systems of ropes and knots to secure articles to a load bearing structure during storage or transportation. Today these systems are commonly referred to as "tie-downs."
In the typical tie-down system, a rope is secured to one side of the truck bed. The remaining loose end of the rope is then coiled and thrown over the top of the load, falling to the ground on the opposite side of the truck.
The teamster then walks to the opposite side of the truck, where he picks up the loose end of the rope and fashions a special hitch in the rope at about shoulder height. This hitch is depicted schematically in FIG. 1 is known as a hay-haulers' hitch, a specific type of rope "tie-down."
The teamster will then pass the rope around some tie point at the side of the truck bed. He will bring the rope from the tie point back up to the special hitch, and pass the rope through the hitch's carefully fashioned loop.
He will pull down on the loose end of the rope. This action will apply tension between the tie point and the loop, and will result in the rope being tightened over the top of the load.
The hay-haulers' hitch includes three lengths of rope between loop and the tie point, (1) a first length descending from the hitch to the tie point, (2) a second length ascending from the tie point back to the loop, and (3) a third length descending from the loop into a user's hands. A mechanical advantage results which allows the user to apply much greater tension to the rope over the load than would be possible were the user pulling directly on the rope over the load.
To secure and lock the hitch, the user ties off the loose end of the rope at some convenient tie point, usually located at the side of the truck bed. A load is thereby made secure upon the bed of a truck.
If the user has correctly tied the hitch it will not come loose as the tension is adjusted. Additionally, if done correctly, the user will maintain his balance and avoid injury. And, if finally, done correctly the tie system will possess sufficient tension across the load so that the 10ad won't shift while the truck is moving.
A walk through any truck stop along major U.S. highways will provide one with the opportunity to observe properly tied and used hitchs, such as that depicted in FIG. 1. Yet, as common as these hitchs are, few outside the trucking industry possess the expertise to master the technique. The hitchs described above remain difficult, if not impossible for persons not having the expertise to tie correctly. Additionally, unless the user practices the tying of these hitchs regularly, the initial learning must be repeated.
As a result of these difficulties, two problems commonly result when a typical user attempts to make a teamsters' tie-down. Firstly, the hitch tends to come loose. This failure may quite likely cause the load to shift while the truck is in motion. Damage not only to the load but the truck are a likely outcome. Additionally, loose loads can be a danger to (1) the driver of the truck because it can be difficult to control the vehicle and (2) fellow motorists who either have to avoid an out of control truck or a spilled load.
Secondly and perhaps with equal frequency, the hitch slips while the tie-down is being adjusted. As the user pulls down on the rope to tighten it as the rope passes over the load, the hitch slips. The user may be thrown off balance and injured.
While the prior art shown in FIG. 1 may prove to be effective among skilled artisans, it has been left to the invention herein to provide a device which is both easy and safe to use. It has also been left to the invention herein to provide a device which secures either large or small loads to a wide variety of load bearing structures.

Detailed Description of the Invention
As described above the prior art is typified by a rope being tied into a hay-haulers' hitch such as that shown in FIG. 1 and generally designated by the numeral 20. Also as pointed out above, it takes considerable practice to develop the expertise to tie such a hitch. The general elements of tying the hay-haulers' hitch 20 and securing articles to a load bearing structure will now be described with reference to FIG. 1.
After the desired articles are placed on a load bearing structure, such as the bed 22 of a pickup truck, one end of a rope 24 is tied to a hook at the side of the bed 22 of a truck and the other end of the rope 24 is brought over the load to the opposite side of the bed 22. The other end of the rope is then crossed over the part of the rope 24 already securing the load. The securing part of the rope is pulled upwardly to form a loop which cradles the rope crossed over the securing part of the rope 24. Using the same end of the rope, the securing part of the rope 24 is formed into a second loop above the first loop. Then, the first loop is passed through the second loop and tightened, by pulling down on the remaining rope. The tightening as described above forms the hitch.
As an alternative to the hay-haulers' hitch 20, the tie down system in accordance with the instant invention is shown in FIGS. 2-14 and will now be described.
FIG. 2 illustrates a tie down system in accordance with this invention, generally designated by the numeral 40. The tie down system 40 includes a securing member 42 for securing articles 44 to a load bearing structure 46.
The securing member 42 is an elongated, flexible body such as a rope, strap, cable, chain or similar structure. The securing member 42 may be made from twine, plastic, metal or other suitable substances.
The tie down system 40 additionally includes a fastener, shown generally by the numeral 48, having a first clip member 50 and a second clip member 52 (FIGS. 3-4). As best seen in FIGS. 3-6, each of the clip members 50 and 52, respectively, has a hook 54 for connecting the respective clip member 50 and 52 to the truck (or load bearing structure) and an eyelet 56 for accepting one end of the securing member 42.
The first clip member 50 has an additional hook 58 for securing and maintaining the securing member 42 in the locked position as will be more fully appreciated below. It will be appreciated from reference to FIGS. 5, 13-14, that each of the hooks, 54 and 58 respectively, define a hook opening 55 and 59, respectively. It will further be appreciated that each of the openings 55 and 59 are open in a direction opposite from one another.
It will be further appreciated that the hook opening 55 is open in a direction approximately 180.degree. from the hook opening 59.
With respect to FIGS. 7-10, there is shown a tensioner 60 for applying and maintaining a tensioning force on the articles 44 through the securing member 42. The tensioner 60 is connected to the securing member 42 and positioned between the first and second clip members, 50 and 52, respectively.
The tensioner 60 includes a body 62 having a first end zone 64 and a second end zone 66. The first end zone includes a hook 67 having an opening 69. The second end zone 64 includes a first leg 68 and a second leg 70.
The first leg 68 has an opening 72 centrally located thereupon. The second leg 70 also has an opening 72 centrally located thereupon. Additionally, the second leg 70 has a notch 74 which is used to retain the securing member 42 in place as will be fully appreciated hereinafter.
FIG. 10 illustrates the tensioner 60 in use. As can be seen, the securing member 42 is connected to the tensioner 60 by threading the securing member 42 through the openings 72. Additionally, the securing member 42 is threaded through openings 72 in such a way that the securing member 42 is pulled against the notch 74 when tension is created on the securing member 42 for securing the articles 44 to the load bearing structure. The securing member 42 is additionally threaded against the opening 69 of the hook 67. By threading the securing member 42 in such a fashion as shown in FIG. 10, the tensioner 60, in cooperation with the fastener 48, causes the securing member 42 to be locked in place.
FIG. 11 illustrates the second clip member 52 fastened to the truck (or load bearing structure). It will be appreciated that the second clip member 52 is fastened to a hook or opening at the sidewall of the truck. It will also be appreciated that the sidewall of the truck is connected to the truck bed. Therefore, the second clip member 52 is connected to the load bearing structure.
FIG. 11 also illustrates one end of the securing member 42 connected to the eyelet 56 of the second clip member 52.
FIG. 12 illustrates the securing member 42 threaded through the openings 72 of the first and second legs, 68 and 70, respectively. The tensioner 60 is depicted in the orientation for allowing the securing member 42 to slide easily through the openings 72.
FIG. 13 illustrates the first clip member 50 of FIGS. 5-6 having its hook 54 connected to the sidewalls of the truck in the same fashion as described with respect to the second clip member 52 of FIG. 11. And, in a manner substantially the same as the second clip member 52, the securing member 42 is connected to eyelet 56 of the first clip member 50.
FIG. 14 illustrates the cooperation of the fastener 48 and the tensioner 60 to lock the securing member 42 in place. In use, the securing member 42 is threaded through the eyelets 56 of the clip members, 50 and 52 and the openings 72 of the tensioner 60. Particularly attention is paid to the manner of threading the tensioner 60 so that the securing member 42 is threaded across the notch 74. This condition is achieved by rotation of the tensioner 60 to a "locked" orientation, as shown best in FIGS. 10 & 14.
One end of the securing member 42 is secured fixedly to the second clip member 52 while the other end is threaded as described above. The securing member 42 is then pulled with as much tension as desired through all of the respective eyelets 56 and openings 72 to apply the amount of tension desired to the articles 44.
After the desired tension is achieved it must be maintained. This is done by looping the securing member 42 around the hooks 58 and 67 of the first clip member 50 and the tensioner 60, respectively. It will be appreciated prior to looping the securing member 42 that the hook openings 59 and 69 of the first clip member 50 and the tensioner 60, respectively should be facing in opposite directions and 180.degree. of opposition has been found to be preferable.
It will be appreciated that the free end of the securing member 42 is then tied off and the notch 74 prevents the securing member 42 from slipping.
While the foregoing detailed description has described several embodiments of the tie-down system in accordance with this invention, it is to be understood that the above description is illustrative only and not limiting of the disclosed invention. Particularly, it should be noted that a variety of tensioners and fasteners may be used to work cooperatively with one another to produce substantially the desired results in accordance with the invention herein. Thus the invention is to be limited only by the claims as set forth below.
