Description

The present invention relates to a tarp and a method for setting up a tarp.

JP 2001-107604 A (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 multiple pull ropes that can be attached to the upper ends of the pair of poles and the bottom of the curtain body.

These tarps are primarily set up at campsites to provide shade, protection from the wind, and rain.

JP 2001-107604 A

In order to set up a conventional tarp, first, the tent is unfolded on the ground, and then pegs or other fasteners are driven into a pair of through-holes in the tent to temporarily secure it so that it will not be blown away by the wind. Next, the position for fasteners to be driven in for hooking the pull ropes supporting the pair of poles is determined by eye or by using the user's body or poles, and the fasteners are driven into the determined position. 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 hooked 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 hooked to the upper ends of the pair of poles is hooked to the fastener that has been positioned and fixed. Next, the pair of poles are alternately erected little by little until they are perpendicular to the ground, and after the pair of poles are perpendicular to the ground, the other end of the pull rope hooked 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.

Thus, when setting up a conventional tarp like the one described in the above publication, it is necessary to remember where to drive in the fasteners to secure the pull ropes that support the pair of poles, and there are unnecessary actions that are not directly related to setting up, such as pulling out the temporarily fixed fasteners, and when setting up the pair of poles little by little, work is required (rework) to readjust the length of the pull rope that was determined by eye. Also, with the tarp described in the above publication, after the pair of poles are erected, the other end of the pull rope that is engaged with the bottom of the tent body is pulled and fixed in place, so it is not possible to determine the area required for setting up the tarp before setting it up, and there are cases where the tarp extends beyond the setup space.

The present invention has been made in consideration of the above, and has as its object to provide a tarp that can be easily set up and a method for setting up the tarp. Another object of the present invention is to provide a tarp and a method for setting up the tarp that allows the area required for setting up to be determined before setting up.

The tarp and method for setting up the tarp of the present invention employ the following measures to achieve the above-mentioned objectives.

In a preferred embodiment of the tarp according to the present invention, the tarp is constructed to be tensioned using at least one pole and a fastener driven into the ground. The tarp comprises a curtain body having an engagement portion capable of engaging with the pole, a tensioning section having a property in which tension acts in the longitudinal direction and a first end portion in the longitudinal direction integrated with the curtain body , and a driving-in position suggestion portion capable of suggesting a driving-in position for the fastener. The tensioning section has a first annular portion at a second end portion in the longitudinal direction through which the fastener can be inserted. The driving-in position suggestion portion is pre -positioned at a position a distance L from the tip of the second end portion of the tensioning section toward the first end portion along the longitudinal direction. The distance L has a value that satisfies the following formula:

(Equation 1)
L = a - b ... (1)
Here, a is the distance between the first intersection and the tip of the second end after the tarp is set up . 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 appears on the tent body after the tarp is set up and includes a ridge line that passes through the engagement part where the pole is engaged . b is the distance between the tip of the second end after the tarp is set up and a second intersection that is the intersection of a virtual vertical line that passes through the first intersection and the ground plane. Here, the "tarp" in the present invention preferably includes not only a tent body that covers the overhead, i.e., a so-called open tarp consisting only of a awning, but also a shelter-type tent including a screen tarp that has a awning and side curtains that cover the sides. Furthermore, the "ridge line" in the present invention is a line that appears on the tent body when the tarp is set up, and corresponds to a mountain-folded line with folds that convex upward.

According to the present invention, since the tarp has a property of exerting tension in the longitudinal direction and the first end in the longitudinal direction is integrated with the curtain body with directionality, when the curtain body and the tensioning section are deployed on the ground plane in setting up the tarp, the tensioning section can be deployed in the optimal position for setting up the tarp. Furthermore, since the position where the fastener should be driven into the ground plane is suggested in advance when the tensioning section is deployed in the optimal position for setting up the tarp, there is no need to remember the positioning method for driving the fastener into the ground plane as with conventional tarps. Furthermore, since the fastener is driven into the suggested position in advance , the tarp can be set up with the appropriate tension, so there is no need to adjust the length of the pull rope during the work of erecting the poles (rework). Furthermore, since the area required for setting up the tarp can be determined before setting up the tarp, there is no inconvenience such as the tarp going beyond the setting up space.

According to a further embodiment of the tarp of the present invention, the first annular portion is configured as a long hole extending in the longitudinal direction, having a first starting end located at the tip of the second end and a first ending end located on the first end side. The setting-in position suggestion portion is the first ending end.

According to this embodiment, after driving the fasteners into the first ends of the long holes in the tensioning section, the tarp can be set up with the appropriate tension simply by 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 actions that are not directly related to setting up the tarp, such as pulling out the temporarily fixed fasteners, as with conventional tarps.

According to a further embodiment of the tarp of the present invention, the casting position indication portion is a visible marking on the tensioned portion.

According to this embodiment, it is possible to realize the driving position suggestion part with a simple configuration by simply marking the tensioned part.

According to a further embodiment of the tarp of the present invention, the tensioning portion has a second annular portion through which the fastener can be inserted. The second annular portion 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 that is greater than the maximum outer dimension of the fastener. The driving-in position suggestion portion is the second starting end.

In this embodiment, the driving position suggestion section can be realized with a simple configuration, since only the second annular section is provided in the tension section.

According to a further embodiment of the tarp of the present invention, the tensioning section further has an adjustment section that allows the longitudinal length to be adjusted.

According to this embodiment, if greater tension than necessary occurs in the tensioned section after the tarp is set up due to unevenness of the ground or, conversely, if the tensioned section becomes loose, fine adjustments can be made so that the tensioned section is at an appropriate level.

According to a further embodiment of the tarp of the present invention having an adjustment section, the adjustment section is disposed closer to the first end of the tensioning section.

In 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 position than in a configuration in which the adjustment section is positioned closer to the fixing device.

According to a further embodiment of the tarp of the present invention having an adjustment portion, the adjustment portion is capable of adjusting the longitudinal length of the first annular portion.

According to this embodiment, the longitudinal length of the first annular portion can be adjusted.

According to a preferred embodiment of the method for setting up a tarp according to the present invention, a tarp is set up using at least one pole and a fastener driven into the ground. Here, the tarp comprises a curtain body having an engagement part that can engage with the pole, a tensioning section that has a property of applying tension in the longitudinal direction and has a first end in the longitudinal direction integrated with the curtain body , and a driving-in position suggestion part that can suggest a driving-in position for the fastener. The tensioning section has a first annular part at a second end in the longitudinal direction through which the fastener can be inserted. The driving-in position suggestion part is pre-positioned at a position a distance L from the tip of the second end of the tensioning section toward the first end along the longitudinal direction that satisfies the following formula: The method of setting up the tarp includes: (a) an unfolding step of unfolding the tent body onto the ground horizontal and unfolding the tensioning portion onto the ground horizontal so that the tensioning portion extends in the longitudinal direction; (b) a driving step of driving the fasteners into the ground horizontal at a position at the distance L indicated by the driving indication portion ; and (c) an installation step of engaging the posts with the engagement portions and installing the posts so that they are perpendicular to the ground horizontal.
(Equation 2)
L = a - b ... (2)
Here, a is the distance between the first intersection and the tip of the second end after the tarp is set up. 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 appears on the tent body after the tarp is set up and includes a ridge line that passes through the engagement part where the pole is engaged. b is the distance between the tip of the second end after the tarp is set up and a second intersection that is the intersection of a virtual vertical line that passes through the first intersection and the ground plane. Here, the "tarp" in the present invention preferably includes not only a tent body that covers the overhead, i.e., a so-called open tarp consisting only of a awning, but also a shelter-type tent including a screen tarp that has a awning and side curtains that cover the sides. Furthermore, the "ridge line" in the present invention is a line that appears on the tent body when the tarp is set up, and corresponds to a mountain-folded line with folds that convex upward.

According to the present invention, since the tarp has a property of exerting tension in the longitudinal direction and the first end in the longitudinal direction is integrated with the curtain body with directionality, when the curtain body and the tensioning part are deployed on the ground plane when the tarp is set up, the tensioning part can be deployed in the optimal position for setting up the tarp. Furthermore, since the position where the fastener should be driven into the ground plane is suggested in advance when the tensioning part is deployed in the optimal position for setting up the tarp, there is no need to remember the positioning method for driving the fastener into the ground plane as with conventional tarps. Furthermore, since the fastener is driven into the suggested position in advance , the tarp can be set up with the appropriate tension, so there is no need to adjust the length of the pull rope during the work of erecting the poles (rework). Furthermore, since the area required for setting up the tarp can be determined before setting up the tarp, there is no inconvenience such as the tarp going beyond the setting up space.

According to a further embodiment of the method for setting up a tarp according to the present invention, the first annular portion is configured as a long hole extending in the longitudinal direction, having a first starting end located at the tip of the second end and a first ending end located on the side of the first end. The driving-in position suggestion portion is the first ending end. Step (b) is a step of inserting a fastener through the first annular portion and driving the fastener into the ground at the first ending end.

According to this embodiment, after driving the fasteners into the first ends of the long holes in the tensioning section, the tarp can be set up with the appropriate tension simply by 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 actions that are not directly related to setting up the tarp, such as pulling out the temporarily fixed fasteners, as with conventional tarps.

According to a further embodiment of the method for setting up a tarp according to the present invention, the driving-in position indication portion is a visible mark marked on the tensioned portion. Step (b) is a step of driving the fastener into the ground plane near the mark. Then, step (c) is a step of installing the pole so that it is perpendicular to the ground plane, and then engaging the first loop portion with the fastener.

According to this embodiment, since it is only necessary to mark the tensioning section, the driving position suggestion section can be realized with a simple configuration, and the tarp can be easily set up.

According to a further embodiment of the method for setting up a tarp according to the present invention, the tensioning section has a second annular section through which the fastener can be inserted. The second annular 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. Step (b) is a step of inserting the fastener into the second annular section and driving the fastener into the ground plane at the second starting end. Step (c) is a step of disengaging the second annular section from the fastener, setting up the post so that it is perpendicular to the ground plane, and then engaging the first annular section with the fastener. Here, in the present invention, "having higher directivity in the longitudinal direction than in the transverse direction" typically refers to a configuration that is difficult to sway (hard to bend) in the transverse direction, but also preferably includes a configuration in which, due to the 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. Also, in the present invention, "tarp" preferably includes not only a so-called open tarp consisting of only a tent that covers the overhead, i.e., a tent, but also a so-called screen tarp that has a tent and side curtains that cover the sides.

In this embodiment, the only thing required is to provide a second annular portion on the tensioning section, which allows for a simple configuration to be realized for the driving position suggestion section and allows for easy pitching of the tarp.

According to a further embodiment of the method for setting up a tarp according to the present invention, the method further includes an adjustment step of adjusting the longitudinal length of the tensioned portion after step (c).

According to this embodiment, if greater tension than necessary occurs in the tensioned section after the tarp is set up due to unevenness of the ground or, conversely, if the tensioned section becomes loose, fine adjustments can be made so that the tensioned section is at an appropriate level.

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.

Next, the best mode for carrying out the present invention will be explained using examples.

As shown in Figures 1 to 3, the tarp 1 according to the embodiment of the present invention comprises an awning 2, six tension 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. 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 the present invention.

As shown in FIG. 3, the awning 2 has a generally rectangular shape in plan view. The fabric of the awning 2 can be a chemical fiber (synthetic fiber) material such as polyester or nylon, or a cotton material or polycotton material. Grommets 2a, 2a are provided at a position near the center of the long side of the awning 2 in the extension direction. 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" in this invention.

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 directivity in the longitudinal direction relative to the transverse direction. In other words, it can be said that the tension belts 4a and 4b have a property that deformation (bending or bending) in the transverse direction is difficult to occur. The tension belt 4a is fixed to the awning 2 at both ends of a pair of short sides of the awning 2 so that the longitudinal direction is along the extension direction of the long side 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 the longitudinal direction is along the direction perpendicular to the extension direction of the long side of the awning 2 (extension direction of the short side of the awning 2). As shown in FIG. 4, the tension belts 4a and 4b are fixed to the awning 2, for example, by sewing, in a manner that deformation (bending or bending) in the transverse direction (see arrow Ds in FIG. 4) is difficult to occur. In other words, the tension belts 4a and 4b have a higher directivity in the longitudinal direction (see arrow Dl in FIG. 4) than in the transverse direction (see arrow Ds in FIG. 4), and can be said to be integrated with the awning 2 with this directivity. It goes without saying that the tension belts 4a and 4b can be fixed to the awning 2 by means of more than just sewing, and can also be fixed, for example, by adhesive. The tension belts 4a and 4b are an example of an embodiment corresponding to the "tensioning section" in the present invention.

As shown in FIG. 5, the tension belts 4a and 4b each have a ring portion 44 at the end 42 opposite to the fixed end 40 to the awning 2. The ring 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 length of the ring portion 44 in the longitudinal direction, i.e., the length from the tip 44a of the ring portion 44 to the base end 44b of the ring portion 44, to be finely adjusted by the buckle 50. In other words, it can be said that the length of the tension belts 4a and 4b in the longitudinal direction can be finely adjusted by the buckle 50. Here, the initial length L of the ring portion 44 in the longitudinal direction is set so that the tension of the tension 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 FIG. 6 and FIG. 7) can be calculated using the following formula (1). In order to easily set the longitudinal length of the annular portion 44 to the initial length L, it is desirable to mark the position of the tension belts 4a and 4b where the longitudinal length of the annular portion 44 is the initial length L, or to configure the annular portion 44 so that its maximum longitudinal length is the initial length L. The fixed end 40 corresponds to the "first end" in the present invention, the end 42 corresponds to the "second end" in the present invention, the annular portion 44 corresponds to the "first annular portion" and the "long hole" in the present invention, the tip 44a corresponds to the "first starting end" in the present invention, and the root end 44b corresponds to the "insertion position suggestion portion" and the "first end" in the present invention. The buckle 50 is an example of an embodiment corresponding to the "adjustment portion" in the present invention.

(Equation 1)
L = a - b (1)
Here, as shown in Figures 6 and 7, a is the distance (length of line segment EP) between the intersection point P and the tip 44a of the annular portion 44 (hereinafter, for convenience, may be referred to as "E"). The intersection point P is the intersection point of a first imaginary straight line VL1 that passes through the tip 44a of the annular 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. Also, b is the distance (line segment EPf) between the tip 44a of the annular portion 44 and the intersection point Pf. The intersection point Pf is the intersection point of a virtual vertical line VVL that passes through the intersection point P and the ground plane. In addition, 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 tension 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 tension belt 4a is unfolded (before the tarp 1 is set up).

Next, a method for setting up the tarp 1 thus constructed will be described. When setting up the tarp 1, as shown in FIG. 2, first, the awning 2 and tension belts 4a, 4a, 4a, 4a, 4b, 4b are deployed on the ground plane. Here, the tension belts 4a, 4a, 4a, 4a, 4b, 4b have higher directivity in the longitudinal direction (see arrow Dl in FIG. 4) than in the transverse direction (see arrow Ds in FIG. 4), and since they are integrated with the awning 2 with this directivity, they are deployed while maintaining a predetermined posture. That is, the tension belts 4a, 4a, 4a, 4a are deployed so as to extend in a direction along the long side of the awning 2, and the tension belts 4a, 4b are deployed so as to extend in a direction perpendicular to the long side of the awning 2. As a result, the tension belts 4a, 4a, 4a, 4a, 4b, 4b are deployed in the optimal position for setting up the tarp 1.

After the tensioning belts 4a, 4a, 4a, 4b, 4b are deployed in the optimal position for setting up the tarp 1, the pegs 8, 8, 8, 8, 8, 8 are inserted into the rings 44 and driven into the ground in alignment with the root ends 44b. 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 set up so that they are perpendicular to the ground (see Figure 6). At this time, the engagement positions of the rings 44 and the pegs 8, 8, 8, 8, 8, 8 change from the root 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. If the tension belts 4a, 4a, 4a, 4a, 4b, 4b are too tightly tensioned or insufficiently tensioned (loose) due to the undulations of the ground, the tension can be finely adjusted using the buckle 50.

As described above, according to the tarp 1 of the embodiment of the present invention, the tension belts 4a, 4a, 4a, 4a, 4b, 4b, which have a higher directivity in the longitudinal direction than in the transverse direction (see arrow Ds in Figure 4), are integrated into the awning 2 with said directivity, and a ring-shaped portion 44 is provided at the end 42 of each of the tension belts 4a, 4a, 4a, 4a, 4b, 4b, and the initial longitudinal length L of the ring-shaped portion 44 is set to satisfy the above-mentioned formula (1). Therefore, when setting up the tarp 1, when the awning 2 and the tension belts 4a, 4a, 4a, 4a, 4b, 4b are deployed on the ground, the tension belts 4a, 4a, 4a, 4a, 4b, 4b can be deployed in the optimal position for setting up the tarp 1. Then, in this state, the pegs 8, 8, 8, 8, 8, 8 are driven into the root ends 44b of the ring-shaped portions 44, the pair of posts 6, 6 are inserted into the eyelets (grommets) 2a, 2a of the awning 2, and the pair of posts 6, 6 are simply set up perpendicular to the ground plane, allowing the tarp 1 to be set up with the appropriate tension. Thus, 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, 8, or to adjust the length of the pull ropes while setting up the posts 6, 6 (rework). In addition, since the area required for setting up the tarp 1 can be determined before setting up the tarp 1, there is no inconvenience of it going beyond the setting up space. Furthermore, there is no need to perform unnecessary actions not directly related to setting up, such as pulling out the temporarily fixed pegs, as with conventional tarps.

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 hexagonal tarp, or a wing tarp as the tarp 1.

In the embodiment of the present invention and the above-mentioned modified example, the present invention is applied to an open tarp, but is not limited thereto. For example, the present invention may be applied to a modified tarp 100 illustrated in Figs. 8 and 9. As shown in Figs. 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 given the same reference numerals, and detailed description thereof will be omitted.

As shown in Figures 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 tension 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.

In the modified tarp 100, the initial length L of the longitudinal direction of the annular portion 44 can also be calculated using the above-mentioned formula (1). However, as shown in Figures 8 and 10, a is the distance (length of line segment EP) between the intersection point P and the tip 44a of the annular portion 44 (hereinafter, for convenience, it may be referred to as "E"). The intersection point P is the intersection point of a first virtual straight line VL1 that passes through the tip 44a of the annular portion 44 after the tarp 100 is set up and extends along the longitudinal direction of the tension belts 4a, 4b, and a second virtual straight line VL2 that includes the ridge line RL that appears on the awning 2 after the tarp 100 is set up. Also, b is the distance (line segment EPf) between the tip 44a of the annular portion 44 and the intersection point Pf. The intersection point Pf is the intersection point between the virtual vertical line VVL that passes through the intersection point P and the ground plane. In FIG. 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 tension 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 tension belt 4a is unfolded (before the tarp 100 is set up).

In the embodiment of the present invention and the above-mentioned modified example, the longitudinal length of the annular portion 44 is set to the initial length L, but this is not limited thereto. For example, as shown in the modified tension belts 204a and 204b illustrated in FIG. 11, the mark 205 may be written at a position of distance L from the tip 244a of each annular portion 244 of the tension belts 204a and 204b, or as shown in the modified tension belts 304a and 304b illustrated in FIG. 12 and the modified tension belts 404a and 404b illustrated in FIG. 13, the tension belts 304a, 304b and the tension belts 404a, 404b are provided with annular portions 344 and 444, respectively, and the distance L is set from the tip 344a of the annular portion 344 and the tip 444a of the annular portion 444 to the tip 345a of the annular portion 345 and the tip 445a of the annular portion 445. 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 descriptions thereof will be omitted.

In a tarp equipped with tension belts 204a, 204a, 204a, 204a, 204b, 204b, the awning 2 and tension belts 204a, 204a, 204a, 204b, 204b are deployed on the ground plane so as to be in the optimum position for setting up the tarp, and then, as shown in FIG. 11, pegs 8, 8, 8, 8, 8, 8 are driven into the ground plane at positions near the marks 205. 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 as to be perpendicular to the ground plane. Finally, the ring portions 244 of the tension belts 204a, 204a, 204a, 204b, 204b are engaged with the pegs 8, 8, 8, 8, 8, 8, 8, to complete the setting up of the tarp. The distance L from the tip 244a of each annular 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 point P (see Figures 6 and 7) and the tip 244a of the annular portion 244 (hereinafter, for convenience, it may be referred to as "E"). Also, b is the distance (line segment EPf) between the tip 244a of the annular portion 244 and the intersection point Pf (see Figures 6 and 7) between the virtual vertical line VVL (see Figures 6 and 7) passing through the intersection point P and the ground plane. Note that the tension belts 204a and 204b correspond to the "tensioned portion" in the present invention, the annular portion 244 corresponds to the "first annular portion" in the present invention, and the mark 205 is an example of an embodiment corresponding to the "hitting position suggestion portion" and "mark" in the present invention.

With this configuration, it is possible to achieve the same effects as the tarp 1 according to the embodiment of the present invention described above, specifically, the effect that the tensioning belts 204a, 204a, 204a, 204a, 204b, 204b can be deployed in the optimal position for setting up the tarp 1, the effect that the tarp 1 can be set up with appropriate tension, the effect that the user does not have to remember how to position the pegs 8, 8, 8, 8, 8, 8 or adjust the length of the pull ropes while setting up the posts 6, 6 (rework), and the effect that the area required for setting up the tarp 1 can be determined before setting up the tarp 1.

The tension belts 304a, 304b and the tension belts 404a, 404b have the annular portion 345 and the annular portion 445, respectively, at a position closer to the fixed end 40 (to the right in Figs. 12 and 13) than the annular portion 344 and the annular portion 444. The annular portion 345 is configured as an elongated hole having a tip 345a and a root end 345b. The annular portion 445 has the tension belts 404a, 404b engaged on both sides of the annular portion 445, and has a tip 445a formed by the tension belts 404a, 404b on one side (the end portion 42 side, the left side in Fig. 13) and a root end 445b formed by the tension belts 404a, 404b on the other side (the fixed end 40 side, the right side in Fig. 13). The annular portion 345 and the annular portion 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. Also, 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. Also, tip 345a and tip 445a correspond to the "drive 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 end" in the present invention.

In a tarp equipped with tensioning belts 304a, 304a, 304a, 304a, 304b, 304b and tensioning belts 404a, 404a, 404a, 404a, 404b, 404b, the 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 annular portion 345 and annular portion 445, 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 through the eyelets (grommets) 2a, 2a, and in this state the pair of posts 6, 6 are installed so as to be perpendicular to the ground plane. Finally, the annular portions 344 and 444 of the tension belts 304a, 304a, 304a, 304b, 304b and the tension belts 404a, 404a, 404a, 404a, 404b, 404b are engaged with the pegs 8, 8, 8, 8, 8, 8, to complete the setup of the tarp. The distance L from the tip 344a of the annular portion 344 and the tip 444a of the annular portion 444 to the tip 345a of the annular portion 345 and the tip 445a of the annular portion 445 can be calculated using the above-mentioned formula (1). Here, a is the distance (length of the line segment EP) between the intersection point P (see Figures 6 and 7) and the tip 344a of the annular portion 344 and the tip 444a of the annular portion 444 (hereinafter, sometimes referred to as "E" for convenience). Also, 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.

With this configuration, it is possible to achieve the same effects as the tarp 1 according to the embodiment of the present invention described above, specifically, the effects that the tension belts 304a, 304a, 304a, 304a, 304b, 304b and tension belts 404a, 404a, 404a, 404a, 404b, 404b can be deployed in the optimal position for setting up the tarp 1, that the tarp 1 can be set up with appropriate tension, that there is no need to remember where to drive the pegs 8, 8, 8, 8, 8, 8, or to adjust the length of the pull ropes while setting up the posts 6, 6 (rework), and that the area required for setting up the tarp 1 can be determined before setting up the tarp 1.

In the embodiment of the present invention and the above-mentioned modified example, the buckle 50 is arranged on the annular portion 44, 244, 344, 444, but this is not limited thereto. The buckle 50 may be arranged in any position as long as the longitudinal length of the tension belt 4a, 4b, 204a, 204b, 304a, 304b, 404a, 404b can be adjusted. For example, the buckle 50 can be arranged in a position closer to the fixed end 40. According to this configuration, since the buckle 50 is arranged closer to the awning 2, the longitudinal length of the tension belt 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 arranged closer to the end 42 (to the peg).

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

As shown in Figures 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 tension 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 descriptions thereof are omitted.

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

The portion including the two vertices 503c, 503c located on the shorter diagonal 503a of the two diagonals 503a, 503b of the awning 502 has the tension belts 4b, 4b integrated therewith and the eyelets (grommets) 2a, 2a. The manner in which the tension belts 4b, 4b are fixed to the awning 502 is the same as in the embodiment of the present invention. The eyelets (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. In addition, the portion including the two vertices 503d, 503d located on the longer diagonal 503b of the two diagonals 503a, 503b of the awning 502 has slits 502a, 502a extending to the diagonal 503b. The slits 502a are an example of an embodiment corresponding to the "first annular portion" in this invention.

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

The length L of the slits 502a, 502a in the extension direction (longitudinal direction) is set so that the tension acting on the awning 502 is an appropriate magnitude when the setup of the tarp 1 is completed. The length L (the length of the line segment ER in FIG. 18) 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 and the tip 544a of the slit 502a (hereinafter, for convenience, may be referred to as "E") as shown in FIG. 18. The intersection point P is the intersection point of the first virtual straight line VL1 passing through the tip 544a and root end 544b of the slit 502a after the tarp 500 is set up, and the second virtual straight line VL2 including the ridge line RL that appears on the awning 502 after the tarp 500 is set up. Also, b is the distance (line segment EPf) between the tip 544a of the slit 502a and the intersection Pf between the imaginary vertical line VVL passing through the 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 position suggestion portion" and "first end" in this invention.

Next, a method for setting up the modified tarp 500 thus constructed will be described. When setting up the modified tarp 500, first, the awning 2 and tensioning belts 4b, 4b are spread out on the ground so as to be 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 the annular portions 44, and the pegs 8, 8 are driven into the ground at the root ends 544b of the slits 502a, 502a, as shown in FIG. 17.

Then, the upper ends of the pair of posts 6, 6 are inserted through the grommets 2a, 2a, and in this state, the pair of posts 6, 6 are set up so that they are perpendicular to the ground (see FIG. 14). At this time, the engagement positions of the rings 44 and the pegs 8, 8 change from the root ends 44b to the tips 44a, and the engagement positions of the slits 502a, 502a and the pegs 8, 8 change from the root ends 544b to the tips 544a. This allows the awning 502 to be tensioned with the appropriate tension, completing the setup of the tarp 500.

If there is a desire to close the slits 502a, 502a after setting up the tarp 500, a fastener (not shown) can be provided in the slits 502a, 502a, and the fastener can be closed after setting up the tarp 500 to block (close) the slits 502a, 502a. If there is a desire to fine-tune the tension because the tension in the awning 502 is too high or insufficient (loosening occurs) due to the undulations of the ground, a configuration can be adopted in which the length of the awning 502 in the direction along the diagonal 503b, i.e., the length of the awning 502 in the longitudinal direction, can be adjusted by a fastener 510, as shown in FIG. 19. If the awning 502 is loose and tension is required, the fastener 510 can be closed to shorten the longitudinal length of the awning 502 and increase the tension applied to the awning 502, as shown in FIG. 19(a). Conversely, if the awning 2 is too tense and tension is required to be reduced, the fastener 510 can be opened to lengthen the longitudinal length of the awning 502 and decrease the tension applied to the awning 502, as shown in FIG. 19(b). Note that multiple fasteners 510 may be arranged in the longitudinal direction of the awning 502. The fastener 510 is an example of an embodiment corresponding to the "adjustment unit" in this invention.

The tarp 500 of the modified example can achieve the same effects as the tarp 1 according to the embodiment of the present invention described above, specifically, the effect that the tension belts 4b, 4b and the portion of the awning 502 where the slits 502a, 502a are located can be deployed to the optimal position for setting up the tarp 500, the effect that the tarp 500 can be set up with appropriate tension, the effect that there is no need to remember how to position the pegs 8, 8, 8, 8 or to adjust the length of the pull rope while setting up the posts 6, 6 (redoing), the effect that the area required for setting up the tarp 500 can be determined before setting up the tarp, and the effect that there is no need to perform unnecessary actions not directly related to setting up, such as pulling out the temporarily fixed pegs, as with conventional tarps.

In the modified tarp 500, the awning 502 is provided with slits 502a, 502a, but this is not limited to the configuration. For example, as shown in the modified tarp 600 illustrated in FIG. 20, the awning 602 may be provided with notches 602a, 602a, and tension belts 604a, 604a may be integrated into the notches 602a, 602a.

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 reference numerals will be used for the same parts as the modified tarp 500, and detailed descriptions thereof will be omitted.

As shown in FIG. 20, the awning 602 has notches 602a and tension belts 604a. The notches 602a are provided to bisect the vertices 603d, which are located on the longer of the two diagonals (not shown) of the awning 602. The tension belt 604a is configured in a ring shape (loop) by the buckle 50, and is integrated with the notches 602a by sewing in a manner in which the notches 602a form part of the ring shape (loop). The awning 602 corresponds to the "awning body" in the present invention, and the notches 602a and tension belt 604a are an example of an embodiment corresponding to the "first ring part" in the present invention.

The tension belts 604a, 604a including the notches 602a, 602a have a length L in the 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 (length of the line segment EP) between the intersection point P (see FIG. 18) and the tip 644a of the tension belt 604a (hereinafter, for convenience, may be referred to as "E"). Also, b is the distance (line segment EPf) between the tip 644a of the tension belt 604a and the intersection point Pf (see FIG. 18) of the virtual 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 corresponds to the "first starting point" in the present invention, and the root end 644b is an example of an embodiment that corresponds to the "injection position suggestion portion" and "first end" in the present invention.

In the embodiment of the present invention and the above-mentioned modified example, a pair of independent poles 6, 6 are used, but this is not limited thereto. For example, as shown in the modified tarp 700 illustrated in FIG. 21, an inverted U-shaped pole 706 may 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 by the awning 702, the poles 6, 6 are replaced by the poles 706, and the tension belts 4a, 4a, 4a, 4a, 4b, 4b are replaced by the tension belts 704a, 704a. Therefore, to avoid duplication, the same reference numerals are used for the same parts as the tarp 1 according to the embodiment of the present invention, and detailed description thereof is omitted.

As shown in FIG. 22, the awning 2 has a generally rectangular shape in plan view. The fabric of the awning 702 can be the same material as the awning 2 described above. Grommets 702a, 702a are provided at both ends of one of a pair of short sides of the awning 702. The awning 702 has a through hole 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 "awning body" in this invention.

The tension belt 704a basically has the same configuration as the tension belt 4a. Therefore, to avoid duplication, the same parts as the tension belt 4a will be given 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 the longitudinal direction is along 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, for example, by sewing, in a manner that is unlikely to cause deformation (bending or deflection) in the short direction (see arrow Ds in FIG. 21). In other words, the tension belt 704a has a higher directivity in the long direction (see arrow Dl in FIG. 21) than in the short direction (see arrow Ds in FIG. 21), and can be said to be integrated with the awning 702 with that directivity. Needless to say, the tension belt 704a can be fixed to the awning 2 by means of, for example, adhesive, and the like, without being limited to sewing. The tension belt 704a is an example of an embodiment corresponding to the "tensioning portion" of the present invention.

As shown in FIG. 22, each tension belt 704a has a loop 44 at the end 42 opposite the fixed end 40 to the awning 702. The initial length L of the loop 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 loop 44 (hereinafter, for convenience, may be referred to as "E"). Also, b is the distance (the line segment EPf) between the tip 44a of the loop 44 and the intersection point Pf (see FIG. 23) of the imaginary vertical line VVL (see FIG. 23) that passes through the intersection point P and the ground plane.

Next, a method for setting up the modified tarp 700 thus constructed will be described. 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 the pegs 8, 8 are driven into the ground at the root end 44b of each annular portion 44, and the pegs 8, 8 are driven into the ground via the grommets 702a, 702a (see FIG. 22). At this time, it is desirable to position the support poles 706 below the awning 702.

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 of the rings 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 an appropriate tension, completing the erection of the tarp 700. Here, the portion of the awning 702 that is in 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.

The tarp 700 of the modified example can achieve the same effects as the tarp 1 according to the embodiment of the present invention described above, specifically, the effect that the awning 702 and tensioning belts 702a, 702a can be deployed in the optimal position for setting up the tarp 700, the effect that the tarp 700 can be set up with the appropriate tension, the effect that the user does not need to remember how to drive the pegs 8, 8, 8, 8 into the ground or the work of adjusting the length of the pull rope while setting up the posts 706 (rework) is not required, the effect that the area required for setting up the tarp 700 can be determined before setting up the tarp, and the effect that no unnecessary actions not directly related to setting up the tarp, such as the action of pulling out the temporarily fixed pegs, are required as with conventional tarps.

This embodiment shows an example of a form for implementing the present invention. Therefore, the present invention is not limited to the configuration of this embodiment.
