1. Field of the Invention
The present invention relates to line and/or strap assemblies used for towing vehicles and the like. More particularly, to a line and/or strap assembly allowing for offset towing configurations.
2. Description of the Related Art
Three point towing line and/or strap (hereinafter referred to either as “line”) assemblies currently known in the art require the pulling vehicle to be substantially centered between the two attachment points of the line to the towed vehicle. In situations where this is not readily possible, towing lines known in the art do not provide optimal transfer of towing forces from the towing vehicle to the towed vehicle.
With these considerations in mind, it is desirable to have solutions of new invention.
The subject invention is directed to a new towing line assembly that permits off-center towing. According to one aspect of the invention, an attachment device comprises a first line having a first loop at one end of the first line and a trolley at the other end of the first line. The attachment device further has a second line having a loop at both ends thereof and extending through the trolley.
According to another aspect of the invention, a towing device is disclosed which comprises a first eyelet bar having a U-shaped element, a fixed axle (also called a pin), and a rotatable element positioned on the pin for rotating thereabout. The device also comprises a first line having a first eyelet at a first end of the first line and a second eyelet at a second end of the first line, wherein the second eyelet is connected to the U-shaped element. A second line extends through the shackle and bears upon the rotatable element. The second line has a first eyelet at a first end of the second line and a second eyelet at a second end of the second line. A first shackle is connected to the first eyelet of the second line and a second shackle is connected to the second eyelet of the second line.
As will be appreciated by those persons skilled in the art, a major advantage provided by the present invention is an attachment device that overcomes the aforementioned shortcomings of prior devices. Additional objects of the present invention will become apparent from the following description.
So that those having ordinary skill in the art to which the subject invention pertains will more readily understand how to make and use the subject invention, preferred embodiments thereof will be described in detail herein with reference to the drawings.
The method and apparatus of the present invention will be better understood by reference to the following detailed discussion of specific embodiments and the attached figures which illustrate and exemplify such embodiments.
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The figures disclosed herein are drawn to scale for the preferred embodiments they depict.
Towing line assembly includes a line 1 which is to be attached to a pulling force and a line 2 which is attached to an element to be pulled. Lines 1 and 2 are preferably straps. The lines may be of single or multi-strand fibers. If multi-strand, they may be braided, woven or wrapped.
Pulling line 1 includes a distal loop or eyelet 4 at a distal end and a central loop or eyelet 6 at center portion 3. line 5 extends between distal loop 4 and central loop 6. Central loop 6 is secured to trolley 7.
Pulled line 2 includes a left portion 8 and a right portion 9. Left portion 8 includes a distal loop or eyelet 10. Distal loop 10 is secured to pulling shackle 11. Right portion 9 includes a distal loop or eyelet 12. Distal loop 12 is secured to pulling shackle 13.
Pulled line 2 is threaded through the eye of trolley 7 so that it is free to move along axle 14. Preferably, axle14 may further have a rotating element thereon upon which line 2 bears. Use of such a rotating element serves to reduce friction between the line 2 and the axle 14. In this way, the trolley acts as a load equalizer through which line 2 extends. Of course, any similarly functioning type of shackle may also be used in place of the trolley.
As shown in
When loop 4 is affixed to a towing vehicle and pulling shackles 11 and 13 are attached to a towed vehicle, tension remains effectively constant on portions 8 and 9 regardless of towing angle. As seen in
Although the particular embodiments shown and described above will prove to be useful in many applications in the towing and the hauling arts to which the present invention pertains, further modifications of the present invention will occur to persons skilled in the art. All such modifications are deemed to be within the scope and spirit of the present invention as defined by the appended claims.
This application claims the benefit of U.S. Provisional Application Ser. No. 61258782 filed on Nov. 6, 2009 and entitled Tow line/Strap Assembly, which is incorporated in its entirety herein by reference.
