DETAILED DESCRIPTION
FIG. 1 is a schematic illustration of an unzipped tow strap bag 100, and FIG. 2 is a schematic illustration of the ends of tow strap bag 100, according to an exemplary embodiment of the disclosure. Optionally, tow strap bag 100 is made up from a tow strap 110 with an open zipper 120 surrounding the entire circumference of tow strap 110, so that a bag can be formed by zipping up zipper 120. In an exemplary embodiment of the disclosure, an extra flap 130 is attached to tow strap 110 on one end to serve as a bottom 150 for tow strap bag 100. Optionally, extra flap 130 is formed by folding over the end of tow strap 110 and sewing it to form a U shaped end. Alternatively, an additional piece of material may be used to form extra flap 130. Optionally, the extra material may be the same as used for tow strap 100 or a different type of material may be used, for example tow strap 110 may be made up from canvas, nylon, plastic, woven metal or any other material that can provide enough strength to serve as a tow strap. Optionally, extra flap 130 may be the same material or it may be harder or softer than the rest of the bag to form bottom 150 with a desired rigidity, since bottom 150 does not serve as part of tow strap 110. Optionally, zipper 120 begins at the bottom of the U shaped end between tow strap 110 and extra flap 130. Optionally, a pull tab 126 is located there to pull a slider 123 that connects between the part of the zipper attached to the extra flap and the part of the zipper that is attached to tow strap 110.
In an exemplary embodiment of the disclosure, zipper 120 ends at the top with an extra zipper extension 140 to form a sealed top 160. Alternatively or additionally, top 160 may or may not include extra zipper extension 140 thus forming a sealable or non-sealable top.
In an exemplary embodiment of the disclosure, a fastening element 170 (e.g. a hook, a claw, a loop) is attached to both ends of tow strap 110. In some embodiments of the disclosure, a different type or different shaped fastening element 170 is attached to each end of tow strap 110, or one end may not include fastening element 170. Optionally, fastening element 170 is attached directly to tow strap 110, for example to a loop 190 provided for accommodating a fastening element near the end of tow strap 110. Alternatively, fastening element 170 may be attached to an extra strap 180 that is coupled to tow strap 110, for example by sewing them together. Optionally, extra strap 180 is reinforced or specially designed to support fastening element 170. Optionally, the use of extra strap 180 prevents fastening element 170 from interfering with zipper 120 to form tow strap bag 100 from tow strap 110.

Optionally, the size is determined based on the size of the tow strap 110 required, and taking into consideration the desired size for the resulting bag.
In some embodiments of the disclosure, tow strap 110 is color coded to let the user know at a glance what strength the tow strap may be used for, for example a yellow tow strap 110 may indicate that tow strap 110 may be used to tow anything up to a mass of 500 Kg, and a red tow strap 110 may indicate that tow strap 110 may be used for a mass greater than 500 Kg, for example between 500-1000 Kg. Optionally, also zipper 120 may be color coded, for example to indicate the volume of the bag. In some embodiments of the disclosure, pull tab 126 includes a functional apparatus, for example a flashlight, a corkscrew or a compass.
FIG. 5A is a schematic illustration of a top view of a zipped up tow strap bag 100, and FIG. 5B is a schematic illustration of a bottom view of a zipped up tow strap bag 100, according to an exemplary embodiment of the disclosure;
Optionally, tow strap bag 100 may be used to enclose a kit of emergency items so that it serves a dual purpose:
a. As the container to hold the items; and
b. As a tow strap 110 that is part of the emergency items.
FIG. 6 is a schematic illustration of a tow strap bag 110 that forms a hazard warning triangle 600, according to an exemplary embodiment of the disclosure. In an exemplary embodiment of the disclosure, the kit may include tow strap 110, hazard warning triangle 600, jumper cables, a flashlight, a jack and various other tools. Optionally, when tow strap bag 110 is unzipped it can serve as tow strap 110. When it is zipped up it can serve as hazard warning triangle 600 and/or as tow strap bag 100.
In an exemplary embodiment of the disclosure, hazard warning triangle 600 is made up by placing reflective strips 610 on tow strap 110 so that when tow strap 110 is zipped up to form tow strap bag 100 a reflective triangle is formed. Optionally, the reflective strips may be adhesively attached to tow strap bag 100 or sewed on. Alternatively, the reflective strips are printed onto tow strap 110. The reflective triangle can be placed on the road or inside a vehicle to serve as a hazard warning triangle 600.
In some embodiments of the disclosure, hazard warning triangle 600 forms an essentially solid triangle as shown in FIG. 6. Alternatively, hazard warning triangle 600 may form an outline of a triangle. In some embodiments of the disclosure, other reflective shapes may be formed to provide other functions.
FIG. 7 is a schematic illustration of a tow strap bag 100 with carrying straps 710, according to an exemplary embodiment of the disclosure. In an exemplary embodiment of the disclosure, carrying straps 710 are attached to predetermined positions on tow strap 110, so that tow strap bag 100 will have carrying straps 710 when it is zipped up to form a bag. In some embodiments of the disclosure, carrying straps 710 may be short and serve as handles for holding the bag. Alternatively, they may be long so that the bag can be worn over a persons shoulder.
In some embodiments of the disclosure, carrying straps 710 are attached with a non permanent attachment (e.g. a buckle 720) so that the carrying straps may be removed when not needed, for example when using tow strap 110 to pull something instead of using it to form a bag. Additionally, the size of the carrying straps 710 may be adjusted
FIGS. 8 to 11 are schematic illustration of an alternative tow strap bag 800, according to an exemplary embodiment of the disclosure. FIG. 8 shows bag 800 in zipped up form. FIG. 9 shows bag 800 with the top removed revealing the inside of bag 800. FIG. 10 shows bag 800 when it is partially unzipped and FIG. 11 shows bag 800 when it is entirely unzipped.
In an exemplary embodiment of the disclosure, tow strap bag 800 includes an elongated tow strap 810 that can be used for example to tow a car, a wagon or other objects. In an exemplary embodiment of the disclosure, the tow strap comprises two zipper halves 850 each having an elongated row of zipper teeth 829 and the two zipper halves are coupled in parallel to each other to tow strap 810, for example sewn or adhesively attached along the elongated axis of the tow strap 810. In an exemplary embodiment of the disclosure one half zipper 850 faces toward one edge of the width of tow strap 810 and the other half zipper 850 faces toward the opposing edge of the width of tow strap 810 with the teeth 829 of the zipper facing toward the edge on both sides. Optionally, the half zippers 850 are coupled to the tow strap 810 so that they do not extend beyond the width of tow strap 810. Thus one side of the tow strap completely hides the half zippers. When using the tow strap 810 to tow objects a clean side 815 without the zipper halves 850 can be placed against rocks, pulleys or other elements to prevent damage to the zipper from being rubbed against various elements. Optionally, when zipping up tow strap 810 bag 800 is formed with the clean side 815 of tow strap 810 on the external side of the bag hiding the zipper.
In an exemplary embodiment of the disclosure, a slider 823 with a pull tab 826 is used to zip up the two half zippers 850 causing the elongated tow strap 810 to form a helix shape serving as a wall for tow strap bag 800. Optionally, the two half zippers coupled to tow strap 810 are shorter than the length of tow strap 810 leaving a portion of tow strap 810 at each end without half zipper 850 coupled to it. A top end 820 is left at the top of tow strap bag 800 and a bottom end 830 is left at the bottom of tow strap bag 800. In an exemplary embodiment of the disclosure, top end 820 and bottom end 830 may be the same size or one end might be longer than the other. Optionally, the length of the ends is 10% to 20% of the length of tow strap 810 or shorter or longer, for example a tow strap 5 meters long may have ends about half a meter long. Optionally, at one end or both ends (820, 830) tow strap 810 is folded over and stitched to form a reinforcement area 826, 836 and a loop, which can be used to hold a hook or to suspend the tow strap from a bar. In some embodiments of the disclosure the ends (820, 830) are half twisted when folded over to form a half twisted loop (824, 834) to make it easier to pull the end (820, 830), more rigid or to make it easier to attach to a car hook. Optionally, in addition to the half twist or instead of it the loop on each end is reinforced with an extra piece of material (822, 832 respectively) coupled to it to protect the tow strap at the position of the loop and/or preserve the rigidity and shape of the loop.
In an exemplary embodiment of the disclosure, tow strap 810 is zipped up as a helix forming a pipe like bag without a top or bottom. Optionally, a bottom flap 860 is provided to seal off the bottom of tow strap bag $00 and/or a top flap 840 is provided to seal off the top of tow strap bag 800. In an exemplary embodiment of the disclosure, bottom flap 860 and top flap 840 can be formed from a different material than tow strap 810, fbr example from the material used to hold the teeth 829 of the half zippers. Optionally, near bottom end 830 and top end 820 the two half zippers cease to be coupled to tow strap 810, for example leaving half a percentage of the tow strap, a meter, half a meter or more or less to allow using the end as a tow strap without the zipper interfering. In an exemplary embodiment of the disclosure, at the bottom end 830, one of the half zippers continues to surround the circumference of bottom flap 860 and the second half zipper meets it after surrounding the circumference and is connected to form the starling position of the zipper. Optionally, at the top end 820 one of the half zippers 850 surrounds the circumference of top flap 840 and the other half zipper 850 ceases, without being connected to top flap 840. In some embodiments of the disclosure both top flap 840 and bottom flap 860 are essentially the same size and shape to form a symmetrically shaped bag, for example both being a rectangle, a circle or an oval. Alternatively, top flap 840 and bottom flap 860 may differ in size and/or shape from each other.
In an exemplary embodiment of the disclosure, top end 820 and/or bottom end 830 are not used to form tow strap bag 800 and can be folded inside the bag when tow strap 810 is zipped up to form tow strap bag 800. Optionally, top end 820 and or bottom end 830 can be left outside tow strap bag 800 to pull the bag or carry it.
In an exemplary embodiment of the disclosure, carrying strap connectors 870 are attached to one or more positions on tow strap 810 for connecting a carrying strap 875 to aid in carrying tow strap bag 800. Optionally, the positions for attaching the carrying strap connectors 870 are calculated so that the carrying strap 875 will be connected between opposite sides of tow strap bag 800 when zipping up tow strap 810.
