Description

[Technical Field]

[0001] The present invention relates to a tarp and a method for setting up the tarp. [Background technology]

[0002] Japanese Patent Publication No. 2001-107604 (Patent Document 1) describes a tarp that includes a pair of poles, a curtain body having a pair of through holes through which the pair of poles can be inserted, and a plurality of pull cords that can be attached to the upper ends of the pair of poles and the bottom of the curtain body.

[0003] The tarp is mainly set up at campsites to provide protection from the sun, wind, and rain. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-107604 Summary of the Invention [Problem to be solved by the invention]

[0005] To set up a conventional tarp, first, the tent is unfolded on the ground, and then fasteners such as pegs are driven into a pair of through-holes in the tent to temporarily secure it so that it will not be blown away by wind or other factors. Next, the positions for fasteners to be driven into the tent to secure the pull ropes supporting the pair of poles are determined by eye or by using the user's body or poles, and the fasteners are driven into the determined positions. The temporarily secured fasteners are then pulled out of the pair of through-holes, and the upper ends of the pair of poles are inserted into the pair of through-holes. One end of the pull rope, adjusted to the length determined by eye, is fastened to the upper ends of the pair of poles protruding from the pair of through-holes and the bottom of the tent, and the other end of the pull rope fastened to the upper ends of the pair of poles is fastened to the fastener that was positioned and fixed. Next, the pair of poles are alternately raised little by little until they are perpendicular to the ground. After the pair of poles are perpendicular to the ground, the other end of the pull rope fastened to the bottom of the tent is pulled and secured to the ground using the fastener. Finally, the tension of each pull rope is adjusted to complete the setup of the tarp.

[0006] Thus, when setting up conventional tarps like the one described in the publications mentioned above, it is necessary to remember how to position the fasteners used to fasten the pull ropes that support the pair of poles, and there are unnecessary actions not directly related to setting up the tarp, such as pulling out temporarily attached fasteners, and there is the need to readjust the length of the pull ropes that was determined by eye (rework) when setting up the pair of poles little by little, making setting up the tarp difficult. Also, with the tarp described in the publications mentioned above, after the pair of poles are set up, the other end of the pull ropes that are fastened to the bottom of the tent body are pulled and secured, so it is not possible to determine the area required for setting up the tarp before setting it up, and there is a possibility that the tarp will extend beyond the set-up space.

[0007] The present invention has been made in view of the above, and one of its objects is to provide a tarp that can be easily set up and a method for setting up a tarp. Another object of the present invention is to provide a tarp and a method for setting up a tarp that allows the area required for setting up to be determined before setting up. [Means for solving the problem]

[0008] The tarp and tarp pitching method of the present invention employ the following means to achieve the above-mentioned object.

[0009] A preferred embodiment of the tarp according to the present invention is a tarp that is tensioned using at least one pole and fasteners that are driven into the ground. The tarp includes a curtain body having an engaging portion that can engage with the pole, a tensioning portion that has higher directivity in the longitudinal direction than in the lateral direction, and a driving-in position suggestion portion that is arranged on the tensioning portion so as to suggest a driving-in position for the fastener. The tensioning portion has a first longitudinal end that is integrated with the curtain body and has directionality. The tensioning portion also has a second longitudinal end that has a first annular portion through which the fastener can be inserted. The driving-in position suggestion portion is arranged at a distance L from the tip of the second end toward the first end along the longitudinal direction. The distance L has a value that satisfies the following equation:

[0010] (Number 1) L=ab (1) Here, a is the distance between the first intersection and the tip of the second end. The first intersection is the intersection of a first imaginary line that passes through the tip of the second end after the tarp is set up and extends along the longitudinal direction, and a second imaginary line that includes the ridge line that appears on the tent body after the tarp is set up. b is the distance between the tip of the second end and a second intersection, which is the intersection of an imaginary vertical line that passes through the first intersection and the ground plane. Here, in this invention, "having higher directionality in the longitudinal direction than in the lateral direction" typically refers to a configuration that is less likely to sway (bend) in the lateral direction, but preferably also includes a configuration in which, due to the shape (design), it is more natural for the tarp to extend, stretch, or unfold in the longitudinal direction than to deform (sway, bend, etc.) in the lateral direction. Furthermore, the term "tarp" in this invention preferably encompasses not only so-called open tarps consisting of only an awning, i.e., a curtain that covers the overhead, but also shelter-type tents, including screen tarps that have an awning and side curtains that cover the sides. Furthermore, the "ridge line" in this invention is the line that appears on the curtain when the tarp is set up, and corresponds to the mountain-like fold line with folds that convex upward.

[0011] According to the present invention, the tensioning section has higher directionality in the longitudinal direction than in the lateral direction, and the first longitudinal end is integrated with the tent body with directionality. Therefore, when the tent body and tensioning section are deployed on the ground, the tensioning section can be deployed in the optimal position for setting up the tarp. Furthermore, with the tensioning section deployed in the optimal position for setting up the tarp, the positions where the fasteners should be driven into the ground are suggested, eliminating the need to memorize how to drive the fasteners, as with conventional tarps. Furthermore, by driving the fasteners into the suggested positions, the tarp can be set up with the appropriate tension, eliminating the need to adjust the length of the pull ropes (rework) while setting up the poles. Furthermore, because the area required for setup can be determined before setting up the tarp, there is no need for the tarp to extend beyond the setup space.

[0012] In a further embodiment of the tarp according to the present invention, the first looped portion is configured as a longitudinally extending slot having a first beginning end located at the tip of the second end portion and a first ending end located on the first end portion side, and the driving position suggestion portion is the first ending end.

[0013] According to this embodiment, the tarp can be set up with the appropriate tension simply by driving the fasteners into the first ends of the elongated holes in the tensioning section and then standing the poles perpendicular to the ground, making it even easier to set up the tarp. Furthermore, with this embodiment, there is no need for unnecessary steps not directly related to setting up the tarp, such as pulling out the temporarily fixed fasteners, as with conventional tarps.

[0014] According to a further aspect of the tarp of the present invention, the driving-in position indication portion is a visible mark marked on the tensioned portion.

[0015] According to this embodiment, since it is only necessary to mark the tensioned portion, the driving position suggestion portion can be realized with a simple configuration.

[0016] In a further embodiment of the tarp according to the present invention, the tensioning section has a second looped section through which the fastener can be inserted. The second looped section has a second starting end located on the second end side and a second ending end located on the first end side, and has an inner dimension larger than the maximum outer dimension of the fastener. The driving-in position suggestion section is the second starting end.

[0017] According to this embodiment, the driving position suggestion section can be realized with a simple configuration, since the second annular section is simply provided on the tension section.

[0018] According to a further aspect of the tarp of the present invention, the tensioning section further has an adjustment section that allows the length in the longitudinal direction to be adjusted.

[0019] According to this embodiment, if greater tension than necessary is generated in the tensioned section after the tarp is set up due to unevenness of the ground or, conversely, if looseness occurs in the tensioned section, fine adjustments can be made so that appropriate tension is generated in the tensioned section.

[0020] According to a further embodiment of the tarp of the present invention having an adjuster, the adjuster is disposed closer to the first end of the tensioning part.

[0021] According to this embodiment, the adjustment section is positioned closer to the first end, i.e., closer to the curtain body, so the length of the tensioning section can be adjusted in a more comfortable posture than in a configuration in which the adjustment section is positioned closer to the fixing device.

[0022] According to a further embodiment of the tarp of the present invention having an adjuster, the adjuster is capable of adjusting the length of the first loop portion in the longitudinal direction.

[0023] According to this embodiment, the length of the first annular portion in the longitudinal direction can be adjusted.

[0024] A preferred embodiment of the method for setting up a tarp according to the present invention involves a method for setting up a tarp using at least one pole and fasteners driven into the ground. The tarp includes a tent body having an engaging portion that can engage with the pole, a tensioning section that has higher directivity in the longitudinal direction than in the transverse direction, and a driving-in position suggesting portion disposed on the tensioning section that can suggest a driving-in position for the fastener. The tensioning section has a first longitudinal end that is integrated with the tent body and has a directionality, and a second longitudinal end that has a first annular portion through which the fastener can be inserted. The method for setting up the tarp includes (a) an unfolding step of unfolding the tent body toward the ground and unfolding the tensioning section toward the ground so that the tensioning section extends in the longitudinal direction; (b) a driving-in step of driving the fasteners into the ground using the driving-in position suggesting portion; and (c) an installation step of engaging the pole with the engaging portion and installing the pole perpendicular to the ground. Here, "having higher directionality in the longitudinal direction than in the transverse direction" in this invention typically refers to an aspect that is difficult to sway (bend) in the transverse direction, but preferably also includes an aspect in which, due to shape (design), it is more natural to extend, stretch, or unfold in the longitudinal direction than to deform (sway, bend, etc.) in the transverse direction. Furthermore, the term "tarp" in this invention preferably includes not only a curtain body that covers the overhead, i.e., a so-called open tarp consisting only of an awning, but also shelter-type tents including screen tarps that have an awning and side curtains that cover the sides.

[0025] According to the present invention, the tensioning section has higher directionality in the longitudinal direction than in the lateral direction, and the first longitudinal end is integrated with the tent body with directionality. Therefore, when the tent body and tensioning section are deployed on the ground, the tensioning section can be deployed in the optimal position for setting up the tarp. Furthermore, with the tensioning section deployed in the optimal position for setting up the tarp, the positions where the fasteners should be driven into the ground are suggested, eliminating the need to memorize how to drive the fasteners, as with conventional tarps. Furthermore, by driving the fasteners into the suggested positions, the tarp can be set up with the appropriate tension, eliminating the need to adjust the length of the pull ropes (rework) while setting up the poles. Furthermore, because the area required for setup can be determined before setting up the tarp, there is no need for the tarp to extend beyond the setup space.

[0026] In a further embodiment of the tarp pitching method of the present invention, the first looped portion is configured as a longitudinally extending slot having a first starting end located at the tip of the second end portion and a first ending end located on the first end side. The driving-in position suggestion portion is the first ending end. Step (b) is a step of inserting a fastener through the first looped portion and driving the fastener into the ground at the first ending end.

[0027] According to this embodiment, the tarp can be set up with the appropriate tension simply by driving the fasteners into the first ends of the elongated holes in the tensioning section and then standing the poles perpendicular to the ground, making it even easier to set up the tarp. Furthermore, with this embodiment, there is no need for unnecessary steps not directly related to setting up the tarp, such as pulling out the temporarily fixed fasteners, as with conventional tarps.

[0028] In a further embodiment of the tarp pitching method of the present invention, the driving-in position indicator is a visible mark on the tensioned portion. Step (b) is a step of driving a fastener into the ground near the mark. Then, step (c) is a step of installing the pole perpendicular to the ground and then engaging the first loop with the fastener.

[0029] According to this embodiment, since it is only necessary to mark the tensioned portion, the driving-in position suggestion portion can be realized with a simple configuration, and the tarp can be easily set up.

[0030] According to a further embodiment of the tarp pitching method of the present invention, the tensioning section has a second looped section through which a fastener can be inserted. The second looped section has a second starting end located on the second end side and a second ending end located on the first end side, and has an inner dimension greater than the maximum outer dimension of the fastener. The driving-in position suggestion section is the second starting end. Step (b) is a step of inserting the fastener into the second looped section and driving the fastener into the ground plane at the second starting end. Step (c) is a step of disengaging the second looped section from the fastener, then installing the pole so that it is perpendicular to the ground plane, and then engaging the first looped section with the fastener. Here, "having higher directionality in the longitudinal direction than in the lateral direction" in this invention typically refers to an aspect that is difficult to sway (bend) in the lateral direction, but preferably also includes an aspect in which, due to shape (design), it is more natural to extend, stretch, or unfold in the longitudinal direction than to deform (sway, bend, etc.) in the lateral direction. Furthermore, the "tarp" in this invention preferably includes not only a curtain body that covers the overhead, i.e., a so-called open tarp consisting only of an awning, but also a so-called screen tarp that has an awning and side curtains that cover the sides.

[0031] According to this embodiment, since only the second annular portion is provided on the tensioning portion, the driving-in position suggestion portion can be realized with a simple configuration, and the tarp can be easily set up.

[0032] According to a further embodiment of the method for setting up a tarp according to the present invention, the method further comprises, after step (c), an adjusting step of adjusting the length of the tensioned part in the longitudinal direction.

[0033] According to this embodiment, if greater tension than necessary is generated in the tensioned section after the tarp is set up due to unevenness of the ground or, conversely, if looseness occurs in the tensioned section, fine adjustments can be made so that appropriate tension is generated in the tensioned section. [Effects of the Invention]

[0034] According to the present invention, a tarp can be easily set up. Furthermore, according to the present invention, the area required for setting up the tarp can be determined before setting up the tarp. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0036] Next, the best mode for carrying out the present invention will be described using examples. [Example]

[0037] As shown in Figures 1 to 3, a tarp 1 according to an embodiment of the present invention includes an awning 2, six tensioning belts 4a, 4a, 4a, 4a, 4b, 4b integrated with the awning 2, a pair of posts 6, 6, and six pegs 8, 8, 8, 8, 8, 8, 8. In this embodiment, a rectangular tarp, which is an open tarp, will be described as an example. The peg 8 is an example of an embodiment corresponding to the "fixing device" in this invention.

[0038] As shown in Figure 3, the awning 2 has a generally rectangular shape in a plan view. The fabric of the awning 2 can be made of chemical fiber (synthetic fiber) material such as polyester or nylon, or cotton or polycotton. Grommets 2a, 2a are provided at approximately the center of the long sides of the awning 2 in the extension direction, near the long sides. The grommets 2a, 2a have through holes with an inner diameter slightly larger than the outer diameter of the upper ends of the pair of posts 6, 6. The awning 2 is an example of an embodiment corresponding to the "curtain body" of the present invention.

[0039] As shown in FIG. 3, the tension belts 4a and 4b have basically the same configuration except for the difference in length. The tension belts 4a and 4b have high directionality in the longitudinal direction relative to the lateral direction. In other words, the tension belts 4a and 4b have the property of being resistant to deformation (bending or deflection) in the lateral direction. The tension belt 4a is fixed to the awning 2 at both ends of the pair of short sides of the awning 2 so that its longitudinal direction is along the extension direction of the long sides of the awning 2. On the other hand, the tension belt 4b is fixed to the awning 2 at approximately the center of the pair of long sides of the awning 2 so that its longitudinal direction is along the direction perpendicular to the extension direction of the long sides of the awning 2 (the extension direction of the short sides of the awning 2). As shown in FIG. 4, the tension belts 4a and 4b are fixed to the awning 2 by sewing, for example, in a manner that is resistant to deformation (bending or deflection) in the lateral direction (see arrow Ds in FIG. 4). In other words, the tension belts 4a, 4b have higher directionality in the longitudinal direction (see arrow Dl in FIG. 4) than in the lateral direction (see arrow Ds in FIG. 4), and can be said to be integrated with the awning 2 with this directionality. It goes without saying that the tension belts 4a, 4b can be fixed to the awning 2 by means other than sewing, and can also be fixed by adhesive, for example. The tension belts 4a, 4b are one example of an embodiment corresponding to the "tensioning section" in this invention.

[0040] As shown in FIG. 5, each of the tensioning belts 4a and 4b has a looped portion 44 at the end 42 opposite the fixed end 40 to the awning 2. The looped portion 44 is formed by folding the tip of the end 42 in half and then engaging the tip with a buckle 50 fixed to the end 42. This allows the longitudinal length of the looped portion 44, i.e., the length from the tip 44a of the looped portion 44 to the base end 44b of the looped portion 44, to be finely adjusted using the buckle 50. In other words, the longitudinal length of the tensioning belts 4a and 4b can be finely adjusted using the buckle 50. Here, the initial longitudinal length L of the looped portion 44 is set so that the tension applied by the tensioning belts 4a and 4b is appropriate when the tarp 1 is set up. Specifically, the initial length L (the length of the line segment ER in FIGS. 6 and 7) can be calculated using the following equation (1). To easily set the longitudinal length of the annular portion 44 to the initial length L, it is desirable to mark the position on the tension belts 4a, 4b where the longitudinal length of the annular portion 44 becomes the initial length L, or to configure the annular portion 44 so that its maximum longitudinal length becomes the initial length L. The fixed end 40 corresponds to the "first end" in this specification, the end 42 corresponds to the "second end" in this specification, the annular portion 44 corresponds to the "first annular portion" and "long hole" in this specification, the tip 44a corresponds to the "first starting end" in this specification, and the root end 44b corresponds to the "insertion position indicating portion" and "first terminal end" in this specification. The buckle 50 is an example of an embodiment corresponding to the "adjustment portion" in this specification.

[0041] (Number 1) L=ab (1) Here, as shown in Figures 6 and 7, a is the distance (length of line segment EP) between intersection P and the tip 44a of the looped portion 44 (hereinafter, sometimes referred to as "E" for convenience). Intersection P is the intersection point of a first imaginary straight line VL1 that passes through the tip 44a of the looped portion 44 after the tarp 1 is set up and extends along the longitudinal direction of the tensioning belts 4a, 4b, and a second imaginary straight line VL2 that includes the ridge line RL that appears on the awning 2 after the tarp 1 is set up. Furthermore, b is the distance (line segment EPf) between the tip 44a of the looped portion 44 and intersection Pf. Intersection Pf is the intersection point of an imaginary vertical line VVL that passes through intersection P and the ground plane. In Figures 6 and 7, R is the root end 44b of the annular portion 44 after the tarp 1 is set up, Ef is the tip 44a of the annular portion 44 when the tensioning belt 4a is unfolded (before the tarp 1 is set up), and Rf is the root end 44b of the annular portion 44 when the tensioning belt 4a is unfolded (before the tarp 1 is set up).

[0042] Next, we will explain how to set up the tarp 1 configured in this manner. To set up the tarp 1, first, as shown in FIG. 2, the awning 2 and tensioning belts 4a, 4a, 4a, 4a, 4b, 4b are unfolded on the ground. Here, the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b have higher directionality in the longitudinal direction (see arrow Dl in FIG. 4) than in the transverse direction (see arrow Ds in FIG. 4), and because they are integrated with the awning 2 with this directionality, they are unfolded while maintaining a predetermined posture. That is, the tensioning belts 4a, 4a, 4a, 4a are unfolded so as to extend in a direction along the long sides of the awning 2, and the tensioning belts 4a, 4b are unfolded so as to extend in a direction perpendicular to the long sides of the awning 2. As a result, the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b are unfolded in the optimal positions for setting up the tarp 1.

[0043] After the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b are deployed in the optimum position for setting up the tarp 1, the pegs 8, 8, 8, 8, 8, 8 are inserted into each loop portion 44 and aligned with the base ends 44b, and then driven into the horizontal ground. Finally, the upper ends of the pair of posts 6, 6 are inserted into the grommets 2a, 2a, and the pair of posts 6, 6 are installed so that they are perpendicular to the horizontal ground (see Figure 6). At this time, the engagement positions between the loop portions 44 and the pegs 8, 8, 8, 8, 8, 8 change from the base ends 44b to the tips 44a. This causes the awning 2 to be tensioned with the appropriate tension, completing the setup of the tarp 1. Furthermore, if the tension belts 4a, 4a, 4a, 4a, 4b, 4b are subjected to too much tension or insufficient tension (loosening occurs) due to unevenness of the ground, the tension can be finely adjusted using the buckle 50.

[0044] As described above, according to the tarp 1 of the embodiment of the present invention, the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b, which have higher directionality in the longitudinal direction than in the short direction (see arrow Ds in Figure 4), are integrated into the awning 2 with this directionality, and a circular portion 44 is provided at the end 42 of each of the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b, and the initial length L in the longitudinal direction of the circular portion 44 is set to satisfy the above-mentioned formula (1).Therefore, when setting up the tarp 1, when the awning 2 and tensioning belts 4a, 4a, 4a, 4a, 4b, 4b are spread out on the ground, the tensioning belts 4a, 4a, 4a, 4a, 4b, 4b can be spread out in the optimum position for setting up the tarp 1. Then, in this state, the tarp 1 can be set up with appropriate tension simply by driving the pegs 8, 8, 8, 8, 8, 8 into the root ends 44b of each annular portion 44, inserting the pair of posts 6, 6 into the eyelets (grommets) 2a, 2a of the awning 2, and erecting the pair of posts 6, 6 perpendicular to the ground. As described above, with the tarp 1 according to this embodiment, unlike conventional tarps, there is no need to remember how to position the pegs 8, 8, 8, 8, 8, or to adjust the length of the pull ropes while erecting the posts 6, 6 (rework). Furthermore, because the area required for setup can be determined before setting up the tarp 1, there is no need to worry about the tarp overhanging the setup space. Furthermore, unlike conventional tarps, there is no need to perform unnecessary steps not directly related to setup, such as pulling out temporarily fixed pegs.

[0045] In the embodiment of the present invention, the present invention is applied to a rectangular tarp as the tarp 1, but is not limited to this. For example, the present invention may be applied to a square tarp, a hexa tarp, or a wing tarp as the tarp 1.

[0046] In the embodiment of the present invention and the above-described modified examples, the present invention has been applied to an open tarp, but is not limited to this. For example, the present invention may be applied to a modified tarp 100 illustrated in Figures 8 and 9. As shown in Figures 8 and 9, the modified tarp 100 has the same configuration as the tarp 1 according to the embodiment of the present invention, except that it is equipped with side curtains 110a, 110a, 110b, 110b, 110c, and 110c. Therefore, the same parts of the modified tarp 100 as those of the tarp 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

[0047] 8 and 9, the modified tarp 100 includes an awning 2, side curtains 110a, 110a, 110b, 110b, 110c, 110c integrated with the awning 2, six tensioning belts 4a, 4a, 4a, 4a, 4b, 4b integrated with the awning 2, a pair of posts 6, 6, and six pegs 8, 8, 8, 8, 8, 8. The modified tarp 100 is configured as a so-called screen tarp.

[0048] In the modified tarp 100, the initial length L of the longitudinal direction of the looped portion 44 can also be calculated using the above-mentioned formula (1). Here, as shown in FIGS. 8 and 10, a is the distance (length of line segment EP) between intersection P and the tip 44a of the looped portion 44 (hereinafter, sometimes referred to as "E" for convenience). Intersection P is the intersection point of a first imaginary line VL1 that passes through the tip 44a of the looped portion 44 after the tarp 100 is set up and extends along the longitudinal direction of the tensioning belts 4a, 4b, and a second imaginary line VL2 that includes the ridge line RL that appears on the awning 2 after the tarp 100 is set up. Furthermore, b is the distance (line segment EPf) between the tip 44a of the looped portion 44 and intersection Pf. Intersection Pf is the intersection point of an imaginary vertical line VVL that passes through intersection P and the ground plane. In Figure 10, R is the root end 44b of the annular portion 44 after the tarp 100 is set up, Ef is the tip 44a of the annular portion 44 when the tensioning belt 4a is unfolded (before the tarp 100 is set up), and Rf is the root end 44b of the annular portion 44 when the tensioning belt 4a is unfolded (before the tarp 100 is set up).

[0049] In the embodiment of the present invention and the modified examples described above, the length in the longitudinal direction of the annular portion 44 is set to the initial length L, but the present invention is not limited to this. For example, as shown in modified tension belts 204a and 204b in FIG. 11, mark 205 may be marked at a position a distance L from the tip 244a of each annular portion 244 of tension belts 204a and 204b, or as shown in modified tension belts 304a and 304b in FIG. 12 and modified tension belts 404a and 404b in FIG. 13, tension belts 304a, 304b and tension belts 404a, 404b may be provided with annular portions 344 and 444, respectively, as well as annular portions 345 and 445, and the distance from tip 344a of annular portion 344 and tip 444a of annular portion 444 to tip 345a of annular portion 345 and tip 445a of annular portion 445 may be set to be a distance L. These modified examples have the same configuration as the tarp 1 according to the embodiment of the present invention, except that the tension belts 4a and 4b are replaced with tension belts 204a and 204b, tension belts 304a and 304b, and tension belts 404a and 404b. Therefore, to avoid duplication, the same reference numerals will be used for the same parts as the tarp 1 according to the embodiment of the present invention, and detailed explanations thereof will be omitted.

[0050] In a tarp equipped with tensioning belts 204a, 204a, 204a, 204a, 204b, 204b, the awning 2 and tensioning belts 204a, 204a, 204a, 204b, 204b are spread out on the ground in the optimum position for setting up the tarp, and then pegs 8, 8, 8, 8, 8, 8 are driven into the ground near the marks 205, as shown in FIG. 11. Next, the upper ends of the pair of posts 6, 6 are inserted into the eyelets (grommets) 2a, 2a, and in this state, the pair of posts 6, 6 are installed so that they are perpendicular to the ground. Finally, the loop portions 244 of the tensioning belts 204a, 204a, 204a, 204b, 204b are fastened to the pegs 8, 8, 8, 8, 8, 8, to complete the setup of the tarp. The distance L from the tip 244a of each looped portion 244 of the tension belts 204a and 204b to the mark 205 can be calculated using the above-mentioned formula (1). Here, a is the distance (length of the line segment EP) between the intersection P (see FIGS. 6 and 7) and the tip 244a of the looped portion 244 (hereinafter, for convenience, sometimes referred to as "E"). Also, b is the distance (line segment EPf) between the tip 244a of the looped portion 244 and the intersection Pf (see FIGS. 6 and 7) between the virtual vertical line VVL (see FIGS. 6 and 7) passing through the intersection P and the horizontal plane. The tension belts 204a and 204b correspond to the "tensioned portion" in this invention, the looped portion 244 corresponds to the "first looped portion" in this invention, and the mark 205 is an example of an embodiment corresponding to the "driving position suggestion portion" and "mark" in this invention.

[0051] With this configuration, it is possible to achieve the same effects as the tarp 1 of the embodiment of the present invention described above, specifically, the effect of being able to deploy the tensioning belts 204a, 204a, 204a, 204a, 204b, 204b in the optimal position for setting up the tarp 1, the effect of being able to set up the tarp 1 with appropriate tension, the effect of not having to remember how to position the pegs 8, 8, 8, 8, 8, 8 or having to adjust the length of the pull ropes while setting up the posts 6, 6 (rework), and the effect of being able to determine the area required for setting up the tarp 1 before setting it up.

[0052] The tension belts 304a, 304b and the tension belts 404a, 404b have the annular portions 345 and 445, respectively, located closer to the fixed end 40 (to the right in FIGS. 12 and 13) than the annular portions 344 and 444. The annular portions 345 are configured as elongated holes having a tip 345a and a base 345b. The tension belts 404a, 404b are engaged on both sides of the annular portion 445, with the tip 445a formed by the tension belts 404a, 404b on one side (the end 42 side, left side in FIG. 13) and the base 445b formed by the tension belts 404a, 404b on the other side (the fixed end 40 side, right side in FIG. 13). The annular portions 345 and 445 have inner dimensions larger than the maximum outer dimensions of the peg 8. Here, tension belts 304a, 304b and tension belts 404a, 404b correspond to the "tensioning portion" in the present invention, and annular portion 344 and annular portion 445 are an example of an embodiment corresponding to the "first annular portion" in the present invention. Furthermore, annular portion 345 and annular portion 445 (including the engagement portion of tension belts 404a, 404b with annular portion 445) are an example of an embodiment corresponding to the "second annular portion" in the present invention. Furthermore, tip end 345a and tip end 445a correspond to the "driving position suggestion portion" and "second starting end" in the present invention, and root end 345b and root end 445b are an example of an embodiment corresponding to the "second ending end" in the present invention.

[0053] In a tarp equipped with tensioning belts 304a, 304a, 304a, 304a, 304b, 304b and tensioning belts 404a, 404a, 404a, 404a, 404b, 404b, 404b, awning 2 and tensioning belts 304a, 304a, 304a, 304a, 304b, 304b and tensioning belts 404a, 404a, 404a, 404a, 404b, 404b are first spread out on the ground in the optimum position for setting up the tarp, and then pegs 8, 8, 8, 8, 8, 8 are driven into the ground at the positions of tips 345a and 445a of ring-shaped portion 345 and ring-shaped portion 445, respectively, as shown in Figures 12 and 13. Next, the engagement between the positions of the annular portions 345a and 445a and the pegs 8, 8, 8, 8, 8, 8 is released. That is, the tension belts 304a, 304a, 304a, 304a, 304b, 304b and the tension belts 404a, 404a, 404a, 404a, 404b, 404b are pulled out from the pegs 8, 8, 8, 8, 8, 8, and then the upper ends of the pair of posts 6, 6 are inserted into the eyelets (grommets) 2a, 2a, and in this state the pair of posts 6, 6 are installed so that they are perpendicular to the ground plane. Finally, the tarp is set up by fastening the looped portions 344 and 444 of the tensioning belts 304a, 304a, 304a, 304b, 304b and the tensioning belts 404a, 404a, 404a, 404a, 404b, 404b to the pegs 8, 8, 8, 8, 8, 8. The distance L from the tip 344a of the looped portion 344 and the tip 444a of the looped portion 444 to the tip 345a of the looped portion 345 and the tip 445a of the looped portion 445 can be calculated using the above-mentioned formula (1). Here, a is the distance (the length of the line segment EP) between the intersection point P (see FIGS. 6 and 7) and the tip 344a of the looped portion 344 and the tip 444a of the looped portion 444 (hereinafter, sometimes referred to as "E" for convenience). Furthermore, b is the distance (line segment EPf) between the tip 344a of the annular portion 344 and the tip 444a of the annular portion 444 and the intersection Pf (see Figures 6 and 7) of the imaginary vertical line VVL (see Figures 6 and 7) passing through the intersection P with the ground plane.

[0054] With this configuration, it is possible to achieve the same effects as the tarp 1 of the embodiment of the present invention described above, specifically, the effects of being able to deploy tensioning belts 304a, 304a, 304a, 304a, 304b, 304b and tensioning belts 404a, 404a, 404a, 404a, 404b, 404b in the optimal position for setting up the tarp 1, the effect of being able to set up the tarp 1 with appropriate tension, the effect of not having to remember how to position the pegs 8, 8, 8, 8, 8, 8 or having to adjust the length of the pull ropes while setting up the posts 6, 6 (rework), and the effect of being able to determine the area required for setting up the tarp 1 before setting it up.

[0055] In the embodiment of the present invention and the above-described modified examples, the buckle 50 is disposed on the loop portion 44, 244, 344, 444, but this is not limiting. The buckle 50 may be disposed in any position as long as it is possible to adjust the longitudinal length of the tensioning belts 4a, 4b, 204a, 204b, 304a, 304b, 404a, 404b. For example, the buckle 50 may be disposed closer to the fixed end 40. With this configuration, the buckle 50 is disposed closer to the awning 2, and therefore the longitudinal length of the tensioning belts 4a, 4b, 204a, 204b, 304a, 304b, 404a, 404b can be adjusted in a more comfortable position than in a configuration in which the buckle 50 is disposed closer to the end 42 (nearer the peg).

[0056] In the embodiment of the present invention and the modified examples described above, the awning 2 is tensioned using the tensioning belts 4a, 4b, 204a, 204b, 304a, 304b, 404a, and 404b, but this is not limiting. For example, as shown in a modified tarp 500 illustrated in Figures 14 and 15, the awning 502 may be tensioned using the awning 502 itself.

[0057] 14 and 15, the modified tarp 500 has the same configuration as the tarp 1 according to the embodiment of the present invention, except that the awning 2 is replaced with an awning 502 and the tensioning belts 4a, 4a, 4a, 4a are deleted. Therefore, the same parts of the modified tarp 500 as those of the tarp 1 are given the same reference numerals and detailed description thereof will be omitted.

[0058] Awning 502 has a generally diamond shape in plan view, as shown in Figures 15 and 16. As with awning 2, the fabric of awning 502 can be made of chemical fiber (synthetic fiber) materials such as polyester and nylon, cotton material, polycotton material, etc. Awning 502 is an example of an embodiment corresponding to the "curtain body" of the present invention.

[0059] Tension belts 4b are integrated with and provided with grommets 2a in a portion including two vertices 503c located on the shorter diagonal 503a of the two diagonals 503a and 503b of the awning 502. The tension belts 4b are fixed to the awning 502 in the same manner as in the embodiment of the present invention. The grommets 2a have through holes with an inner diameter slightly larger than the outer diameter of the upper ends of the pair of struts 6. Furthermore, slits 502a extending along the diagonal 503b are provided in a portion including two vertices 503d located on the longer diagonal 503b of the two diagonals 503a and 503b of the awning 502. The slits 502a are an example of an embodiment corresponding to the "first annular portion" in this invention.

[0060] Here, due to the shape (design) of awning 502, it is natural that the portions including vertices 503d, 503d will unfold in opposite directions along diagonal line 503b. In other words, the portions of awning 502 in which slits 502a, 502a are provided can be said to have higher directivity in the longitudinal direction (see arrow Dl in FIG. 16) than in the lateral direction (see arrow Ds in FIG. 16). Furthermore, it can be said that slits 502a, 502a are integrated into awning 502 with this directivity. As a result, the portions of awning 502 including slits 502a, 502a can be unfolded in the optimal position for setting up tarp 500.

[0061] Furthermore, the length L of the slits 502a, 502a in their extension direction (longitudinal direction) is set so that the tension acting on the awning 502 is an appropriate magnitude when the tarp 1 is set up. The length L (the length of the line segment ER in FIG. 18) can be calculated using the above-mentioned formula (1). Here, as shown in FIG. 18, a is the distance (the length of the line segment EP) between the intersection point P and the tip 544a of the slit 502a (hereinafter, for convenience, may be referred to as "E"). The intersection point P is the intersection point between a first imaginary straight line VL1 that passes through the tip 544a and base end 544b of the slit 502a after the tarp 500 is set up, and a second imaginary straight line VL2 that includes the ridge line RL that appears on the awning 502 after the tarp 500 is set up. Furthermore, b is the distance (line segment EPf) between the tip 544a of the slit 502a and the intersection Pf of the imaginary vertical line VVL passing through intersection P and the ground plane. Ef is the tip 544a of the slit 502a when the awning 502 is unfolded (before the tarp is set up), and Rf is the root end 544b of the slit 502a when the awning 502a is unfolded (before the tarp is set up). The tip 544a corresponds to the "first starting end" in this invention, and the root end 544b is an example of an embodiment corresponding to the "driving-in position suggestion portion" and "first ending end" in this invention.

[0062] Next, we will explain how to set up the modified tarp 500 configured in this way. When setting up the modified tarp 500, first, the awning 2 and tensioning belts 4b, 4b are spread out on the ground in the optimum position for setting up the tarp 500, and then the pegs 8, 8 are driven into the ground at the root ends 44b of each looped portion 44, and the pegs 8, 8 are driven into the ground at the root ends 544b of the slits 502a, 502a, as shown in Figure 17.

[0063] Next, the upper ends of the pair of supports 6 are inserted through the grommets 2a, and in this state, the pair of supports 6 are installed so that they are perpendicular to the ground (see FIG. 14). At this time, the engagement positions between each annular portion 44 and the pegs 8 change from the base ends 44b to the tips 44a, and the engagement positions between the slits 502a and the pegs 8 change from the base ends 544b to the tips 544a. This causes the awning 502 to be tensioned with appropriate tension, completing the setup of the tarp 500.

[0064] If there is a desire to close the slits 502a, 502a after setting up the tarp 500, a configuration can be adopted in which fasteners (not shown) are provided in the slits 502a, 502a, and the slits 502a, 502a can be closed by closing the fasteners after setting up the tarp 500. Furthermore, if there is a desire to fine-tune the tension because too much tension or insufficient tension (loosening) is applied to the awning 502 due to unevenness of the ground, a configuration can be adopted in which the length of the awning 502 in the direction along the diagonal line 503b, i.e., the length of the awning 502 in the longitudinal direction, can be adjusted by fasteners 510, as shown in Fig. 19. When awning 502 is loose and tension is to be applied, as shown in FIG. 19(a), closing fastener 510 shortens the longitudinal length of awning 502 and increases the tension applied to awning 502. Conversely, when awning 502 is too tight and tension is to be reduced, as shown in FIG. 19(b), opening fastener 510 increases the longitudinal length of awning 502 and decreases the tension applied to awning 502. Note that multiple fasteners 510 may be arranged in the longitudinal direction of awning 502. Fastener 510 is an example of an embodiment corresponding to the "adjustment portion" of the present invention.

[0065] The modified tarp 500 can also achieve the same effects as the tarp 1 according to the embodiment of the present invention described above, specifically, the effect of being able to deploy the tensioning belts 4b, 4b and the portion of the awning 502 where the slits 502a, 502a are located in the optimal position for setting up the tarp 500, the effect of being able to set up the tarp 500 with appropriate tension, the effect of not having to remember how to position the pegs 8, 8, 8, 8 or having to adjust the length of the pull ropes while setting up the posts 6, 6 (rework), the effect of being able to determine the area required for setting up the tarp 500 before setting it up, and the effect of not having to perform unnecessary actions not directly related to setting up, such as pulling out temporarily fixed pegs, as with conventional tarps.

[0066] In the modified tarp 500, slits 502a, 502a are provided in the awning 502, but this is not limiting. For example, as shown in a modified tarp 600 illustrated in Fig. 20, notches 602a, 602a may be provided in the awning 602, and tension belts 604a, 604a may be integrated with the notches 602a, 602a.

[0067] The modified tarp 600 has the same configuration as the modified tarp 502, except that the awning 502 is replaced with the awning 602. Therefore, to avoid duplication, the same parts as those in the modified tarp 500 will be denoted by the same reference numerals, and detailed descriptions thereof will be omitted.

[0068] As shown in Fig. 20, the awning 602 has notches 602a and tension belts 604a. The notches 602a are provided so as to bisect vertices 603d, which are located on the longer of two diagonals (not shown) of the awning 602. The tension belt 604a is formed into a loop by the buckle 50, and is integrated with the notches 602a by stitching so that the notches 602a form part of the loop. The awning 602 corresponds to the "tent body" of the present invention, and the notches 602a and the tension belt 604a are an example of an embodiment corresponding to the "first loop portion" of the present invention.

[0069] The tensioning belts 604a, 604a including the notches 602a, 602a have a length L in their extension direction (longitudinal direction) set so that the tension acting on the awning 602 is an appropriate magnitude when the tarp 600 is set up. The length L can be calculated using the above-mentioned formula (1). Here, a is the distance (the length of the line segment EP) between the intersection point P (see FIG. 18) and the tip 644a of the tensioning belt 604a (hereinafter, for convenience, may be referred to as "E"). Also, b is the distance (the line segment EPf) between the tip 644a of the tensioning belt 604a and the intersection point Pf (see FIG. 18) between the imaginary vertical line VVL (see FIG. 18) passing through the intersection point P and the ground plane. The modified tarp 600 configured in this way can also achieve the same effects as the modified tarp 500. The tip 644a is an example of an embodiment that corresponds to the "first starting end" of the present invention, and the root end 644b is an example of an embodiment that corresponds to the "driving position suggestion portion" and the "first terminal end" of the present invention.

[0070] In the embodiment of the present invention and the above-described modified example, a pair of independent poles 6, 6 are used, but this is not limited to this. For example, as shown in the modified tarp 700 illustrated in FIG. 21, a configuration using an inverted U-shaped pole 706 may also be used. The modified tarp 700 has the same configuration as the tarp 1 according to the embodiment of the present invention, except that the awning 2 is replaced with an awning 702, the poles 6, 6 are replaced with poles 706, and the tension belts 4a, 4a, 4a, 4a, 4b, 4b are replaced with tension belts 704a, 704a. Therefore, to avoid duplication, the same parts as those in the tarp 1 according to the embodiment of the present invention will be designated by the same reference numerals, and detailed description thereof will be omitted.

[0071] As shown in Fig. 22, the awning 2 has a generally rectangular shape in a plan view. The same material as the awning 2 described above can be used as the fabric for the awning 702. Grommets 702a, 702a are provided at both ends of one of a pair of short sides of the awning 702. The awning 702 has through holes with an inner diameter slightly larger than the outer diameter of the peg 8. The awning 702 is an example of an embodiment corresponding to the "curtain body" of the present invention.

[0072] The tension belt 704a basically has the same configuration as the tension belt 4a. Therefore, to avoid redundancy, the same parts as the tension belt 4a will be denoted by the same reference numerals, and detailed descriptions thereof will be omitted. The tension belt 704a is fixed to the awning 702 at both ends of the other of the pair of short sides of the awning 702 so that its longitudinal direction is aligned with the extension direction of the long side of the awning 702. As shown in FIG. 21 , the tension belt 704a is fixed to the awning 702 by sewing, for example, in a manner that makes it difficult for deformation (bending or flexing) to occur in the short side direction (see arrow Ds in FIG. 21 ). In other words, the tension belt 704a has higher directivity in the long side direction (see arrow Ds in FIG. 21 ) than in the short side direction (see arrow Ds in FIG. 21 ), and it can be said that the tension belt 704a is integrated with the awning 702 with this directivity. It goes without saying that the tension belt 704a may be fixed to the awning 2 by means of, for example, adhesive or the like, and the tension belt 704a is an example of an embodiment corresponding to the "tensioning portion" of the present invention.

[0073] As shown in FIG. 22, each tension belt 704a has a looped portion 44 at its end 42 opposite the fixed end 40 to the awning 702. The initial length L of the looped portion 44 in the longitudinal direction (the length of the line segment ER in FIG. 23) can be calculated using the above-mentioned formula (1). Here, a is the distance (the length of the line segment EP) between the intersection point P (see FIG. 23) and the tip 44a of the looped portion 44 (hereinafter, for convenience, may be referred to as "E"). Furthermore, b is the distance (the line segment EPf) between the tip 44a of the looped portion 44 and the intersection point Pf (see FIG. 23) between the imaginary vertical line VVL (see FIG. 23) passing through the intersection point P and the ground plane.

[0074] Next, we will explain how to set up the modified tarp 700 configured in this way. When setting up the modified tarp 700, first, the awning 702 and tensioning belts 704a, 704a are spread out on the ground in the optimum position for setting up the tarp 700, and then pegs 8, 8 are driven into the ground at the root ends 44b of each looped portion 44, and the pegs 8, 8 are driven into the ground via grommets 702a, 702a (see FIG. 22). At this time, it is desirable to position the support poles 706 below the awning 702.

[0075] Next, the poles 706 are installed so that an imaginary plane including the poles 706 is perpendicular to the ground (see Figures 21 and 23). At this time, the engagement positions between each loop 44 and the pegs 8, 8 change from the root ends 44b to the tips 44a. This causes the awning 702 to be stretched with appropriate tension, completing the setup of the tarp 700. Here, the portion of the awning 702 that comes into contact with the poles 706, i.e., the portion that forms the ridge line RL (see Figure 23), is an example of an embodiment corresponding to the "first engagement portion" of the present invention.
