Abstract
Description
[Technical Field]
[0001] This invention relates to a bicycle bag with a zipper attached to a tarp. [Background technology]
[0002] When traveling camping and using a bicycle and train as transportation, it was necessary to carry both a bicycle bag to carry the bicycle onto the train and a tarp for camping. Summary of the Invention [Problem to be solved by the invention]
[0003] Carrying a tarp and a bike bag increases the weight and number of items you have to carry, making bicycle travel less comfortable. Also, because bicycles are a means of transportation, the maximum load capacity is low, so in some cases it is impossible to do both. [Means for solving the problem]
[0004] This invention attaches a zipper to a tarp to give it the functionality of a bicycle bag, reducing the number and weight of items to be carried when traveling by bicycle. [Effects of the Invention]
[0005] With the tarp of this invention, whereas previously it was necessary to carry two items, a tarp and a bike bag, this invention allows you to carry just one item, which reduces the number of items you need to carry and the total weight of your luggage, improving comfort and making bicycle trips that were previously thought impossible possible possible. [Brief explanation of the drawings]
[0006] [Figure 1] FIG. 2 is a development view showing the positions of the fasteners attached to the tarp of the present invention. [Figure 2] This is a diagram of the tarp of this invention being used as a bike bag. DETAILED DESCRIPTION OF THE INVENTION
[0007] The tarp of this invention has one side of a pair of zippers sewn from the center of the right side of the long piece of the tarp along the upper short side to the center of the left side of the opposite long piece, and the other side of the pair of zippers attached from the center of the right side of the long piece of the tarp along the lower short side to the center of the left side of the opposite long piece, and a slider for opening and closing the zipper is inserted on the end of the zipper in the center of the left and right sides to close the zipper, and another slider is inserted inside the zipper next to it to close the inside of the zipper, but the starting position of the slider, the route taken when attaching the zipper, and the starting position are not important.When the zipper is fully closed with the slider, it forms a bag shape and must be large enough to store a bicycle. [Example]
[0008] An example will be explained using Figure 1. Reference numeral 1 denotes a rectangular tarp with a long side measuring approximately 2 meters and a short side measuring approximately 1 meter. Reference numeral 2 denotes the long side of the tarp, 3 denotes the short side of the tarp, and 4 denotes one side of a zipper sewn to the tarp, which can be opened and closed using the opposite zipper and slider 5.
[0009] An example of its use as a bike bag will be explained using Figure 2. Figure 2 shows a bicycle stored inside the bike bag. 5 is a set of zipper sliders that form a pair, creating an opening of a few centimeters through which a string can be passed. 6 is a string that is tied to the bicycle body in some way, passing through one side of the opening in 5 and then through the other opening in 5, and then tied to the bicycle body in some way. By putting the center of 6 over one's shoulder, a bicycle traveler can lift the bicycle together with the adjustable bike bag tarp, allowing them to board a train. [Explanation of symbols]
