Abstract

A container for a tie down strap includes a housing with upper and lower walls and a rotatable shaft extending between the upper and lower walls. The shaft has a slot formed therethrough through which the free end of one strap of the tie down strap is journaled. A handle on the end of the shaft permits rotation of the shaft to wind the strap free end around the shaft. A tensioner member extending inwardly from a side wall of the housing is resilient, and engages the strap wound around the shaft, to frictionally engage the strap and bias against free rotation of the shaft.

[0002] (Not applicable)

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates generally to tie down straps used to secure loads on trucks, and more particularly to a container for storage of the loose end of a tie down strap during use, and for long term storage.

(2) Background Information

It is common in the trucking industry to utilize elongated straps to secure loads on a support surface. Straps are preferred to ropes or cable, because they are less likely to tangle or knot, they provide a greater area of contract on the load, thereby distributing the pressure of the straps and thereby reducing the likelihood of damage to the load by the tie downs.

However, tie down straps still suffer several problems. First, in use, there is typically a length of strap extending from the securement ratchet which must be tied off or secured in some fashion, to prevent the free end of the strap from flapping and fraying in the wind.

In order to lengthen the life of a tie down strap, the strap should be wrapped in a coil when not in use. Because the straps are typically exposed to rain, dirt, and are often frayed, the straps are typically bundled in a wad and stowed in a box or other container, without taking the time to properly wind the straps into a coil.

BRIEF SUMMARY OF THE INVENTION

It is therefore a general object of the present invention to pro vide an improved container for storage of a tie down strap.

Another object of the present invention is to provide a tie down strap container which will store the free end of a tie down strap during use of the strap to secure loads.

A further object is to provide a tie down strap holder which permits the majority of the tie down strap to be wound into a small coil and stored in a small protected housing.

These and other objects of the present invention will be apparent to those skilled in the art.

The container for a tie down strap of the present invention includes a housing with upper and lower walls and a rotatable shaft extending between the upper and lower walls. The shaft has a slot formed therethrough through which the free end of one strap of the tie down strap is journaled. A handle on the end of the shaft permits rotation of the shaft to wind the strap free end around the shaft. A tensioner member extending inwardly from a side wall of the housing is resilient, and engages the strap wound around the shaft, to frictionally engage the strap and bias against free rotation of the shaft.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, and more particularly to FIG. 1, the tie down strap container of the present invention is designated generally at [0020] 10 and is shown connected to the free end 12 of a conventional tie down strap 14. Tie down strap 14 includes a first strap 16 having a hook 18 connected thereto, which will be secured to a frame 20 to secure a load. A ratchet mechanism 22 has a rotatable ratcheted shaft 24 upon which an intermediate portion of first strap 16 is wound, which is operable to lengthen and shorten the length of first strap 16 between ratchet mechanism 22 and hook 18. A second strap 26 has one end fastened to ratchet mechanism 22 and a hook 28 on the opposing end which is secured to a second frame 30. Thus, a load is secured by operating ratchet mechanism 22 to shorten the length of first strap 16 and pull the strap tight between hooks 18 and 28.
It can be seen in FIG. 1 that [0021] free end 12 of first strap 16 would flap in the wind, while the tie down strap is in use securing a load. The container 10 is utilized to enclose and secure the first strap free end 12, to prevent damage to the strap, and to store the first strap when not in use, as described in detail hereinbelow.
Referring now to FIGS. [0022] 2-5, tie down strap container 10 includes a lightweight housing 32 of plastic or other weather resistant material. Housing 32 includes an upper wall 34, bottom wall 36, a forward wall 38, opposing side walls 40 and 42, and an opening 44 formed in the rearward end to permit access within the interior of housing 32. A shaft 46 extends through openings in the upper and bottom walls 34 and 36, generally centrally within housing 32, and has a flared lower end 48 preventing withdraw of the shaft through the bottom wall 36. A handle or crank 50 is mounted on the upper end of shaft 46 to permit rotation of the shaft within the housing.
An [0023] elongated slot 52 is formed along the longitudinal axis of shaft 46 and extends therethrough. Slot 52 is of a length to permit the strap free end 12 to be journaled therethrough, as shown in FIGS. 4 and 5.
Once strap [0024] free end 12 has been threaded through slot 52, crank 50 is rotated to rotate shaft 46 and thereby wind strap free end 12 around shaft 46. A tensioner 54 formed of a rigid but flexible piece of plastic or spring steel is mounted to an interior surface of forward wall 38, and has a free end 54 a positioned substantially tangent to the cylindrical surface of shaft 46. As strap free end 12 is wrapped around shaft 46, the strap will form a coil of increasing diameter which will contact the free end 54 a of tensioner 54, bending tensioner 54. Tensioner 54 is a resilient member, which thereby applies a biasing force against strap free end 12, thereby holding the strap in position to prevent free rotation of shaft 46, and thereby preventing accidental uncoiling of strap free end 12 from the shaft 46.
As shown in FIGS. 3 and 5, a [0025] clip 56 is mounted on the exterior surface of housing bottom wall 36, which will permit removable securement of housing 32 to first down strap 16, as shown in FIG. 1. Thus, clip 56 prevents housing 32 from being blown about in the wind during use.
A [0026] flange 58 is formed on side wall 40, and has an aperture 60 formed therethrough, as shown in FIGS. 2 and 3, which will permit attachment of a safety lanyard to housing 32.
A plurality of [0027] ridges 62 are formed on the exterior surfaces of upper and bottom walls 34 and 36, adjacent side wall 42, to permit gripping of housing 32 by the hand. Substantially all of first strap 16 may be wound within housing 32, when the tie down strap is not in use, such that hooks 18 and 26 and ratchet mechanism 22 are the only portions of the tie down strap which are not wound within housing 32 Thus, the entire tie down strap is stored neatly in a small package and may be easily stored and retrieved. In addition, the strap is maintain in good condition by virtue of the fact that the strap is wound in a coil and protected from the elements within housing 32. Also, housing 32 is quickly and easily removed from the tie-down strap, for use with other straps, as desired.
Whereas the invention has been shown and described in connection with the preferred embodiment thereof, many modifications, substitutions and additions may be made which are within the intended broad scope of the appended claims. [0028]
