Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, various functions are required for the ground sheet laid on the ground below the canopy sheet. Suppression of the intrusion of water and insects onto the ground sheet is one example. Therefore, for the purpose of suppressing the intrusion of water etc., a ground sheet in which a wall portion standing in the direction intersecting with the ground is formed around the sheet has been proposed.

[0005] In addition, for the ground sheet, it is required to be easy to install, not to complicate the entry and exit to the shelter etc., to utilize the inside of the shelter as widely as possible, etc. Further, when a wall portion is formed on the ground sheet, it is required that the wall portion is not easily toppled.

[0006] However, to date, no ground sheet has been proposed that can be laid inside shelters or similar structures to form walls, allowing for ample use of the interior space, being easy to install, and having walls that are resistant to collapse.

[0007] Therefore, the present invention aims to provide a ground sheet that allows for ample use of the interior space of shelters and the like, is easy to install, and has walls that are less likely to collapse. [Means for solving the problem]

[0008] The ground sheet of the present invention is a camping ground sheet to be laid on the ground, comprising a floor portion that faces the ground, and a wall portion provided around the floor portion and extending in a direction that intersects with the ground when laid on the ground, and further comprising an attachment provided on the wall portion and extending in a direction that intersects with the ground when laid on the ground, and having an engaging portion at its tip. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a ground sheet that is easy to install and whose wall portion is less likely to collapse. [Brief explanation of the drawing]

[Figure 6B]Figure 6B is a plan view of the living sheet and shows another example of how tension is applied. [Modes for carrying out the invention]

[0011] (Living room sheet) A living sheet 1 according to an embodiment of the present invention will be described with reference to the drawings. The living sheet 1 is an example of a ground sheet according to the present invention. Figure 1 is a perspective view of the living sheet 1 according to this embodiment. Figure 1 shows the living sheet 1 laid on the ground 200.

[0012] Living sheet 1 is laid on the ground 200 below the canopy sheet of a shelter or similar structure. More specifically, living sheet 1 is laid on the exposed ground 200 inside a shelter or screen tarp.

[0013] (Shelters, etc.) Referring to Figure 2, the shelter etc. laid inside the living sheet 1 will be described. Figure 2 is a perspective view of the shelter 100. The shelter 100 shown in Figure 2 is an example of a shelter etc. The shelter 100 mainly comprises a first main pole 111, a second main pole 112, and a cover sheet 115. In addition, a part of the cover sheet 115 forms a canopy sheet section 116 stretched in a triangular roof shape.

[0014] The exposed ground 200 inside the shelter 100 is called the internal ground 210. In the shelter 100 shown in Figure 2, the main panel 120 is rolled up to show the internal ground 210. By rolling up the main panel 120, an opening 113 is formed on one side of the shelter 100. Figure 2 shows the internal ground 210 as seen through the opening 113.

[0015] (floor) Referring to FIG. 1 again, the living sheet 1 will be described. The living sheet 1 includes a floor portion 10 and a wall portion 50. The floor portion 10 is a portion that contacts the ground 200 and spreads on the ground 200 when the living sheet 1 is laid on the ground. One main surface of the floor portion 10 is called the front surface 11, and the other main surface is called the back surface 12.

[0016] The back surface 12 is the surface that contacts the ground 200 when the living sheet 1 is laid on the ground 200. The front surface 11 is the surface on the opposite side of the back surface 12. In FIG. 1, the back surface 12 is not visible and the front surface 11 is visible. The front surface 11 is the surface on which people can sit or lie down. Outdoor furniture such as a table and chairs may be placed on the front surface 11.

[0017] (In all directions) In FIG. 1, the direction vertically away from the ground 200 is shown as the upward direction 1001. The direction opposite to the upward direction 1001 is shown as the downward direction 1002. Looking at an object in the downward direction 1002 is called a plan view.

[0018] (Wall portion) The outer edge of the floor portion 10 in a plan view is called the edge portion 15. The edge portion 15 can also be said to be the perimeter of the floor portion 10. The portion extending along the upward direction 1001 from the edge portion 15 of the floor portion 10 is called the wall portion 50. The length in the upward direction 1001 of the wall portion 50 is shown as the length 501. The length 501 is the height of the wall portion 50. The length 501 can be, for example, 20 mm or more and 200 mm or less.

[0019] The wall portion 50 is provided connected to the entire perimeter of the edge portion 15 of the floor portion 10. When the wall portion 50 is viewed in a plan view, it forms a closed loop.

[0020] The shape of the floor section 10 in plan view is octagonal. The floor section 10 is octagonal because the shape of the interior ground 210 in the shelter 100 shown in Figure 2 is octagonal. The shape and size of the floor section 10 in plan view are compatible with the shape and size of the interior ground 210. Compatibility means that the shape and size of the floor section 10 in plan view are matched to the shape and size of the interior ground 210. By matching the shape and size of the floor section 10 in plan view to the shape and size of the interior ground 210, almost the entire interior ground 210 can be covered with the living sheet 1. This allows for effective use of the interior of the shelter 100.

[0021] Furthermore, the statement that the shape and size of the floor section 10 in plan view match the shape and size of the interior ground 210 does not merely mean that the shape and size of the floor section 10 are identical to the shape and size of the interior ground 210. Matching includes cases where there are differences between the shape and size of the floor section 10 and the shape and size of the interior ground 210. Matching also includes cases where the shape and size of the floor section 10 and the shape and size of the interior ground 210 are largely identical.

[0022] Figure 2 shows the bottom shape of the shelter 100 with a dashed line 141. The bottom shape 141 is also the outline of the interior ground 210. As shown in Figure 1, the floor portion 10 of the living sheet 1 covers most of the bottom shape 141.

[0023] (Mounting hardware) The attachment of the living sheet 1 to the shelter 100 will be explained with reference to Figures 3 and 4, in addition to Figures 1 and 2. Figure 3 is an enlarged view showing a part of the interior 110 of the shelter 100. Figure 4 is an enlarged view showing the part to which the living sheet 1 is attached to the shelter 100.

[0024] As shown in Figure 3, when the living sheet 1 is attached to the shelter 100, the living sheet 1 is attached to the inner surface 122 of the shelter 100. The living sheet 1 is attached to the shelter 100 by engaging the attachments provided on the living sheet 1 with the attachments provided on the shelter 100. The attachments provided on the living sheet 1 are called the sheet-side attachments 30. The attachments provided on the shelter 100 are called the shelter-side attachments 130.

[0025] As shown in Figure 1, the sheet-side mounting bracket 30 is provided on the wall portion 50. The upper end 1001 of the wall portion 50 is called the upper wall portion 510. The sheet-side mounting bracket 30 is provided on the upper wall portion 510. Here, "provided on the upper wall portion 510" does not strictly mean that it is provided only on the upper wall portion 510, but broadly includes being provided in the vicinity of the upper wall portion 510, and being provided on the upper wall portion 510 side of the wall portion 50 rather than the floor portion 10 side. In other words, the sheet-side mounting bracket 30 is provided on the upper side of the wall portion 50.

[0026] Furthermore, the sheet-side mounting bracket 30 is provided so as to be able to lift the wall section 50 upward 1001. This allows the sheet-side mounting bracket 30 to prevent the wall section 50 from collapsing. Specifically, as shown in Figure 3, the shelter-side mounting bracket 130 is located above the sheet-side mounting bracket 30 when the living sheet 1 is attached to the shelter 100. Therefore, by engaging the sheet-side mounting bracket 30 with the shelter-side mounting bracket 130, the living sheet 1 is attached to the shelter 100 and the wall section 50 is lifted upward.

[0027] More specifically, the shelter-side mounting bracket 130 and the sheet-side mounting bracket 30 extend as a series in a direction intersecting the ground 200 when the living sheet 1 is attached to the shelter 100. Of the multiple, engaged, and series-connected shelter-side mounting brackets 130 and sheet-side mounting brackets 30, at least some extend along the upward direction 1001.

[0028] The shelter-side mounting bracket 130 can be provided on the inner surface 122 of the cover sheet 115 that constitutes the shelter 100. Alternatively, the shelter-side mounting bracket 130 may be provided on the skeletal member 126 included in the shelter 100. The skeletal member 126 includes, for example, frame members and wire members that define the shape of the shelter 100.

[0029] The number of sheet-side mounting brackets 30 is the same as the number of shelter-side mounting brackets 130. In other words, there is one shelter-side mounting bracket 130 for each sheet-side mounting bracket 30.

[0030] (Seat-side mounting hardware) Referring to Figure 4, the configurations of the sheet-side mounting device 30 and the shelter-side mounting device 130 will be described. First, the sheet-side mounting device 30 will be described. The sheet-side mounting device 30 includes a mounting cord portion 31 and a hook portion 32. The mounting cord portion 31 is made of a rubber cord. Both ends of the rubber cord are fixed to the wall portion 50. The rubber cord forms a closed loop. The hook portion 32 is attached to the loop formed by the rubber cord. The hook portion 32 has a hook-shaped portion 321 at its tip. The hook-shaped portion 321 is hooked onto the ring portion 132 of the shelter-side mounting device 130, which will be described later.

[0031] (Shelter-side mounting bracket 130) Next, the shelter-side mounting bracket 130 will be described. The shelter-side mounting bracket 130 includes a mounting bracket base 131 and a ring portion 132. The mounting bracket base 131 is made of a fibrous material. The mounting bracket base 131 has a belt shape. The belt-shaped member constituting the mounting bracket base 131 is called the belt member. Both ends of the belt member are fixed to the inner surface 122 of the shelter 100. The belt member forms a closed loop. The ring portion 132 is attached to the loop formed by the belt member. The ring portion 132 is a member formed in a ring shape from a hard resin. The hook-shaped portion 321 of the sheet-side mounting bracket 30 is hooked onto the ring portion 132.

[0032] As shown in Figure 4, by engaging the hook-shaped portion 321 of the sheet-side mounting bracket 30 with the ring portion 132 of the shelter-side mounting bracket 130, the shelter-side mounting bracket 130 can suspend the entire living sheet 1 downwards while lifting the wall portion 50 upwards 1001.

[0033] The configuration and shape of the sheet-side mounting bracket 30 and the shelter-side mounting bracket 130 described above are illustrative examples. The configuration and shape of the sheet-side mounting bracket 30 and the shelter-side mounting bracket 130 can be changed as appropriate. The sheet-side mounting bracket 30 and the shelter-side mounting bracket 130 only need to engage with each other and suspend the wall section 50 upward 1001.

[0034] Referring to Figure 1, the positions where the sheet-side mounting brackets 30 are provided will be described. In the example shown in Figure 1, the shape of the floor portion 10 is an octagon in plan view. One sheet-side mounting bracket 30 is provided at each of the eight corners. However, the positions where the sheet-side mounting brackets 30 are provided on the wall portion 50 are not limited to the example shown in Figure 1. If the floor portion 10 is a polygon in plan view, the sheet-side mounting brackets 30 may be provided at some of the corners of the polygon, rather than all of them. Also, the sheet-side mounting brackets 30 may be provided at locations other than the corners. If the floor portion 10 is not a polygon, such as a circle or an ellipse in plan view, the sheet-side mounting brackets 30 may be provided at any position and at any interval.

[0035] Referring to Figure 5, the conventional living sheet 2001 will be described. Figure 5 shows the conventional living sheet 2001 laid out inside the shelter 2100.

[0036] As shown in Figure 5, conventional living sheet 2001 is provided with support members 2030 around its perimeter to prevent the wall section 2050 from collapsing. In conventional living sheet 2001, numerous support members 2030 must be provided on the outside of the floor section 2010 to prevent the wall section 2050 from collapsing. Therefore, there is a risk that, for example, a child may trip over the support members 2030 and fall.

[0037] In contrast, in the living sheet 1 of this embodiment, the sheet-side mounting fixture 30 provided on the wall section 50 is engaged with the shelter-side mounting fixture 130 of the shelter 100, thereby attaching the living sheet 1 to the shelter 100 and lifting the wall section 50 upward 1001 to prevent it from collapsing. This ensures that the wall section 50 is safely and reliably positioned upward and prevented from collapsing.

[0038] The floor portion 2010 of the conventional living sheet 2001 is rectangular in shape when viewed from above. The shape of the floor portion 2010 is not designed to match the shape of the shelter 100. Therefore, when the living sheet 2001 is laid inside the shelter 100, a portion of the ground 200 is exposed between the inner surface 2122 of the shelter 2100 and the living sheet 2001. This exposed portion of the ground 200 is called the exposed ground portion 2200. In the conventional living sheet 2001, the exposed ground portion 2200 is formed inside the shelter 2100. In other words, the interior of the shelter 2100 is not adequately utilized.

[0039] In contrast, in the living sheet 1 of this embodiment, the shape of the floor portion 10 in plan view is almost the same as the shape of the internal ground 210. Therefore, it is possible to avoid forming an exposed ground portion 2200, or even if an exposed ground portion 2200 is formed, its area can be reduced.

[0040] A gap 2300 may exist between the lower end 2114, which is the lower end 1002 of the shelter 2100, and the ground 200. Water or insects may enter through this gap 2300 from the outside of the shelter 2100 towards the inside, and consequently towards the living sheet 2001. In addition, wind may blow through this gap 2300 from the outside of the shelter 2100 towards the inside.

[0041] When using the living sheet 2001, the user is usually at a height close to the ground 200. In most cases, the user sits on the surface 11 of the floor 10 without using a chair or anything similar. Therefore, compared to bringing a chair into the shelter 2100 and sitting on it, water, insects, and wind coming through the gaps 2300 are more likely to be a concern, making the user more likely to feel uncomfortable. With the conventional living sheet 2001, it is difficult to lay the living sheet 2001 so that the wall section 2050 blocks the gaps 2300. With the conventional living sheet 2001, although there is a wall section 2050 that stands on top 1001, it is difficult to block the gaps 2300 with the wall section 2050.

[0042] In contrast, in the living sheet 1 of this embodiment, as shown in Figure 3, by engaging the sheet-side attachment 30 provided on the wall portion 50 with the shelter-side attachment 130 of the shelter 100, the gap 300 between the lower end 114, which is the lower end 1002 of the shelter 100, and the ground 200 can be sealed by the wall portion 50. Even if the gap 300 is not completely sealed by the wall portion 50, most of the gap 300 can be sealed by the wall portion 50. Therefore, in the living sheet 1 of this embodiment, discomfort caused by the intrusion of water, insects, and wind through the gap 300 can be improved.

[0043] (ground fixture) The method for securing the living sheet 1 to the ground 200 will now be described. As shown in Figure 1, the living sheet 1 is provided with a ground fixing device 40 for securing the living sheet 1 to the ground 200. The ground fixing device 40 is mainly made of a rubber cord. Both ends of the rubber cord are fixed to the floor 10. The rubber cord forms a closed loop. The closed loop is pulled in a predetermined direction along the ground 200 and fixed to the ground 200 using pegs or the like. In this way, the living sheet 1 can be secured to the ground 200.

[0044] The ground fixing device 40 will be described in more detail with reference to Figure 4. As shown in Figure 4, the ground fixing device 40 includes a fixing device base 41 and a fixing device string portion 42. The fixing device base 41 is provided on the floor portion 10. The fixing device base 41 is made of a fibrous material and forms a closed loop. The fixing device string portion 42 is attached to the closed loop of the fixing device base 41. The fixing device string portion 42 is made of a rubber cord. The fixing device string portion 42 forms a loop. In the example shown in Figure 4, the fixing device string portion 42 forms a double loop. The fixing device string portion 42 may be subjected to strong tension. Therefore, it is preferable that the loop of the fixing device string portion 42 be, for example, a double loop. Furthermore, because the ground fixing device 40 includes a fixing device base 41 and a fixing device string portion 42, if the rubber cord of the fixing device string portion 42 breaks, the ground fixing device 40 can be easily repaired by replacing the rubber cord.

[0045] (elastic cord) As described above, it is preferable that the attachment strap portion 31 of the sheet-side attachment device 30 and the fixing strap portion 42 of the ground fixing device 40 are made of rubber straps. By making the attachment strap portion 31 and the fixing strap portion 42 of rubber straps, the attachment strap portion 31 or the fixing strap portion 42 are less likely to break even if they are accidentally stepped on. In addition, by making the attachment strap portion 31 and the fixing strap portion 42 of rubber straps, the attachment strap portion 31 and the fixing strap portion 42 do not take up much space when the living sheet 1 is folded and stored, and the sheet material of the living sheet 1 is less likely to be damaged.

[0046] Referring to Figures 6A and 6B, the method of attaching the living sheet 1 to the ground 200 using the ground fixing device 40 will be explained. Both Figures 6A and 6B are plan views of the living sheet 1.

[0047] As shown in Figures 6A and 6B, if the shape of the floor 10 is polygonal, one ground fixing device 40 can be provided at each corner. When fixing the living sheet 1 to the ground while smoothing out wrinkles in the living sheet 1 by pulling the fixing string portion 42 of the ground fixing device 40, it is preferable to pull two opposing fixing string portions 42 as a pair. This makes it less likely for wrinkles to form in the floor 10.

[0048] The double arrows A1 and A2 in Figure 6A, and the double arrow A3 in Figure 6B, indicate the direction in which two opposing fastening cords 42 are pulled as a pair, that is, the direction of the tension generated by pulling. When the floor 10 is octagonal, two methods of pulling the two opposing fastening cords 42 as a pair can be considered: pulling in one of two orthogonal directions (directions of double arrows A1 and A2) as shown in Figure 6A, or pulling in diagonal directions (directions indicated by double arrow A3) as shown in Figure 6B.

[0049] Here, in order to cover the interior ground 210 as widely as possible and to maximize the area of ​​the floor section 10, it is preferable to pull in one of two orthogonal directions, as shown in Figure 6A. Therefore, it is preferable that the ground fixing devices 40, particularly the fixing device bases 41, be provided on the floor section 10 so as to facilitate pulling in one of two orthogonal directions, rather than in diagonal directions at each corner. Specifically, it is preferable to define two orthogonal directions and provide the fixing device bases 41 perpendicular to the side perpendicular to the defined directions at the two sides forming each corner. For example, at the two sides forming the corner 600 shown in Figure 6A, side 601 and side 602, the fixing device base 41, i.e., the ground fixing device 40, is provided on side 601, which is perpendicular to direction 610. Also, the fixing device base 41 is provided perpendicular to side 601 so as to extend from side 601 in the direction of direction 610. The same applies to the other ground fixing devices 40. This makes it possible to increase the floor area of ​​the floor section 10.

[0050] One reason why the setup shown in Figure 6A allows for a larger floor area 10 than the setup shown in Figure 6B is that it reduces the area of ​​the region near the first main pole 111 and the second main pole 112 where a floor area 10 cannot be provided. In the setup shown in Figure 6A, the width of the region near the first main pole 111 where a floor area 10 cannot be provided is shown by length 161. Length 161 is the distance from the edge 15 of the floor area 10 to the bottom shape 141 of the shelter 100. Similarly, in the setup shown in Figure 6B, the width of the region near the first main pole 111 where a floor area 10 cannot be provided is shown by length 162. Length 161 is the distance from the edge 15 of the floor area 10 to the bottom shape 141 of the shelter 100. As shown in Figures 6A and 6B, length 161 is shorter than length 162. The above explanation has used the first main pole 111 as an example, but the same applies to the second main pole 112.

[0051] In other words, the method of installation shown in Figure 6A can reduce the area of ​​the region near the main poles 111 and 112 where a floor section 10 cannot be provided, compared to the method of installation shown in Figure 6B. As a result, it can be seen that the method of installation shown in Figure 6A can increase the area of ​​the floor section 10 compared to the method of installation shown in Figure 6B.

[0052] Furthermore, the distance from the edge 15 of the floor section 10 to the bottom shape 141 of the shelter 100 may be intentionally made longer. For example, the length 163 shown in Figure 6A is longer than the length 161 described earlier. For example, on the front panel side, by making the distance from the edge 15 to the bottom shape 141 longer, a utility space such as a shoe rack can be created.

[0053] (Ground sheet) The Living Sheet 1 has been described above as an example of a ground sheet. The uses of the ground sheet of the present invention are not limited to living sheets. For example, the ground sheet of the present invention can also be used as a ground sheet. A ground sheet is a sheet on which a tent, or an inner tent in a tent including an outer tent and an inner tent, is placed.

[0054] When using the ground sheet of the present invention as a ground sheet and placing a tent on it, for example, the sheet-side attachment 30 may be fixed to the outer surface of the tent. This prevents the bottom surface and lower part of the tent from becoming soiled with dirt or damp from moisture in the ground.

[0055] Furthermore, when using the ground sheet of the present invention as a ground sheet and placing the inner tent of a tent including an outer tent on it, the sheet-side attachment 30 may be fixed to the inner surface of the outer tent, for example. This prevents the bottom surface and lower part of the inner tent from becoming soiled with dirt or damp from moisture in the ground. In addition, it prevents water from seeping in from the outside of the outer tent and wetting the inner tent with that water.

[0056] The embodiments of the present invention have been described above. The present invention is not limited to the embodiments described above, and various modifications, variations, and combinations are possible.

[0057] (1) The ground sheet is a camping ground sheet to be laid on the ground, comprising a floor portion that faces the ground, and a wall portion provided around the floor portion and extending in a direction that intersects with the ground when laid on the ground, and further comprising a sheet-side attachment provided on the wall portion and extending in a direction that intersects with the ground when laid on the ground, and having a sheet-side engaging portion at its tip.

[0058] According to the above configuration, the ground sheet can be attached via the wall portion by a sheet-side attachment that extends in a direction intersecting with the ground. This makes it possible to provide a ground sheet that is easy to install while the wall portion is less likely to collapse.

[0059] (2) The ground sheet described above may be laid inside the shelter, and the engaging portion may be engaged with the inner surface of the shelter.

[0060] According to the above configuration, the ground sheet can be easily laid to cover most of the interior of the shelter.

[0061] (3) The ground sheet described above is laid inside the shelter, and the floor portion may have a shape and size that conforms to the shape of the bottom surface of the shelter.

[0062] According to the above configuration, the interior of the shelter can be used effectively.

[0063] (4) A shelter with a ground sheet is a shelter comprising a shelter and a ground sheet laid inside the shelter, further comprising a shelter-side attachment provided on the inner surface of the shelter, wherein the ground sheet comprises a floor portion facing the ground and a wall portion provided around the floor portion and extending in a direction intersecting the ground when laid on the ground, and further comprising a sheet-side attachment provided on the wall portion and extending in a direction intersecting the ground when laid on the ground, and engaging with the shelter-side attachment.

[0064] According to the above configuration, the ground sheet can be attached via the wall section by a sheet-side attachment that extends in a direction intersecting with the ground. This makes it possible to provide a ground sheet attached shelter that is easy to install and whose walls are less likely to collapse.

[0065] (5) In the above-described ground sheet attached shelter, the floor portion may have a shape and size that conforms to the shape of the bottom surface of the shelter.

[0066] According to the above configuration, the interior of the shelter can be used effectively.

[0067] (6) In the above-described ground sheet attached shelter, the ground sheet is attached to the shelter by engaging the sheet-side attachment with the shelter-side attachment, When the sheet-side mounting bracket is engaged with the shelter-side mounting bracket, the sheet-side mounting bracket and the shelter-side mounting bracket may extend together in a direction that intersects the ground.
