It includes 10c and two vertical columns 10d arranged on the back surface. The front vertical column 10a is inclined so that its upper end is closer to the back than the lower end, the rear vertical column 10d is inclined so that its upper end is closer to the front than the lower end, and the vertical column 10b on the left side is The upper end thereof is inclined so as to be closer to the right side surface than the lower end surface, and the vertical columns 10c on the right side surface are arranged so that the upper end thereof is inclined so as to be closer to the left side surface than the lower end surface. The twelve vertical columns 10 all have substantially the same length, and their upper ends are arranged on the same horizontal plane.

The lower frame portion 20 connects the lower portions of the 12 vertical columns 10 and has a substantially rectangular shape which is the same as the planar shape of the tent 1. The lower frame 20 is not arranged between the two vertical columns 10a arranged on both sides of the entrance portion P.

The frame-shaped portion 30 connects the upper ends of adjacent vertical columns 10 and has a substantially rectangular shape that is the same as the planar shape of the tent 1. As described above, since the upper ends of the 12 vertical columns 10 are arranged on the same horizontal plane, the frame-shaped portion 30 is arranged substantially parallel to the horizontal plane.

The upper frame portion 31 has a plurality of horizontal frames 32. The plurality of horizontal frames 32 are the four horizontal frames 33a and the four horizontal frames 33b arranged substantially parallel to the short side direction of the tent 1, and the three horizontal frames 33b arranged substantially parallel to the long side direction of the tent 1. Includes a horizontal frame 34, two horizontal frames 35 arranged on the front surface of the tent 1, and two horizontal frames 36 arranged on the back surface of the tent 1.

The horizontal frame 33a and the horizontal frame 33b each connect the four connecting portions of the vertical columns 10b on the left side to the frame-shaped portion 30 and the four connecting portions of the vertical columns 10c on the right side to the frame-shaped portion 30, respectively. As described above, the tent 1 is arranged along the short side direction. _{The horizontal frame 33a and the horizontal frame 33b each have curved portions 33a 1} and 33b ₁ that extend upward from the frame-shaped portion 30 and then curve in the horizontal direction. The horizontal frame 33a and the horizontal frame 33b arranged on substantially the same straight line are connected at the central portion in the short side direction of the tent 1. In the horizontal frame 33a and the horizontal frame 33b, the portion of the _{tent 1 on the short side direction central portion side from the curved portions 33a 1} and 33b ₁ is substantially linear, and is arranged upward as it approaches the short side direction central portion of the tent 1. It is tilted so that it will be.

The connecting portions of the horizontal frame 33a and the horizontal frame 33b are connected by the horizontal frame 34, respectively. Therefore, the three horizontal frames 34 are arranged along the long side direction of the tent 1 at the central portion in the short side direction of the tent 1. The four horizontal frames 33a are arranged on the left side side of the central portion in the short side direction of the tent 1, and the four horizontal frames 33b are arranged on the right side surface side of the central portion in the short side direction of the tent 1. ..

The indoor tent 1 has a roof portion 3 arranged on the upper part of the tent 1 and a seat member 12 attached to the side surface of the tent 1.

The roof portion 3 has a frame-shaped portion 30 included in the frame structure 2, a plurality of horizontal frames 32, an annular sheet 50, and a plurality of short width sheets 60.

The annular sheet 50 is stretched along the frame-shaped portion 30 over the entire circumference of the upper part of the tent 1. The annular sheet 50 is formed continuously and integrally in an annular shape, and has a substantially rectangular opening 50a. The annular sheet 50 has mounting holes 50b arranged at both ends in the longitudinal direction thereof. The mounting hole 50b is formed so as to be openable and closable by a hook-and-loop fastener (not shown), and is switched to an open state when the annular sheet 50 is mounted on the outer periphery of the frame-shaped portion 30. That is, with the mounting holes 50b open, the two horizontal frames 35 arranged on the front surface of the tent 1 and the two horizontal frames 36 arranged on the back surface are passed through the mounting holes 50b, respectively, to form an annular shape. The sheet 50 is attached to the outer periphery of the frame-shaped portion 30. After that, in the mounting hole 50b, the portion between the two horizontal frames 35 and the portion between the two horizontal frames 36 are closed.

The annular sheet 50 is arranged in front of the tent 1 so as to extend upward from the outer peripheral portion of the frame-shaped portion 30 and close between the lateral frames 33a and 33b on the most front side and the frame-shaped portion 30. Similarly, the annular sheet 50 is arranged on the back surface of the tent 1 so as to extend upward from the outer peripheral portion of the frame-shaped portion 30 and close between the lateral frames 33a and 33b on the rearmost side and the frame-shaped portion 30. To.

Further, the annular sheet 50 is arranged on the left side surface and the right side surface of the tent 1 so as to extend upward from the outer peripheral portion of the frame-shaped portion 30 and cover _{the curved portions 33a 1} and 33b _{1 of the horizontal frames 33a and 33b.} ..

FIG. 3 shows the annular sheet 50 in a state of being removed from the frame structure 2, but the size of the outer peripheral portion formed in the annular shape is slightly smaller than the size of the outer peripheral portion of the frame-shaped portion 30. Therefore, when the annular sheet 50 is attached to the frame structure 2, the annular sheet 50 is stretched along the frame-shaped portion 30 with an appropriate tension.

The plurality of short width sheets 60 have a rectangular shape having a predetermined width, and are arranged on the upper portion of the tent 1 along the long side direction of the tent 1 in a state of being separated from each other. Specifically, four short width sheets 60 are arranged parallel to each other between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b, respectively. As shown in FIG. 4, the short width sheet 60 is suspended from a string-shaped member 61 stretched between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b.

The string-shaped member 61 is stretched between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b so as not to be loosened by a fixing member (not shown) attached to the upper part of the horizontal frame 33a and the horizontal frame 33b. There is. The surface of the short width sheet 60 is arranged in parallel in the vertical direction while being suspended from the string-shaped member 61. The short width sheet 60 is, for example, a cloth sheet or a resin sheet, but the material of the short width sheet 60 is arbitrary.

As shown in FIG. 2, a side gap portion 11 is formed between adjacent vertical columns 10 on the side surface of the frame structure 2, but in the indoor tent 1, as shown in FIG. 1, the side gap portion is appropriately formed. A side sheet 12 covering the 11 is attached. In FIG. 2, among the 10 side gaps 11 formed between the adjacent vertical columns 10, only the six side gaps 11 arranged on the front surface and the right side of the tent 1 are designated. ..

In the frame structure 2 of the indoor tent 1, 12 side gaps 11 are formed, and as shown in FIG. 1, the side gaps 10a formed between the two vertical columns 10a arranged in front of the side gaps 11 are formed. The side surface sheet 12 is not arranged in the side gap portion 11 formed between the eleven and the two vertical columns 10d arranged on the back surface thereof. Therefore, on the front and back of the indoor tent 1, the internal space and the external space of the tent 1 communicate with each other.

That is, in the indoor tent 1, between the vertical columns 10a arranged in the front and the vertical columns 10b arranged on the most front side on the left side, between the four vertical columns 10b arranged on the left side, and the left side surface. Between the vertical columns 10b arranged on the rearmost side and the vertical columns 10d arranged on the back surface, and between the vertical columns 10b arranged on the rearmost side on the right side and the vertical columns 10d arranged on the back surface. Ten side gaps 11 formed between the four vertical columns 10c arranged on the right side surface, between the vertical columns 10a arranged on the front surface and the vertical columns 10c arranged on the most front side on the right side surface. A side sheet 12 that covers each side gap 11 is attached to the surface.

As shown in FIG. 5, the side sheet 12 has substantially the same size as one side gap portion 11. The side sheet 12 is, for example, a cloth sheet or a resin sheet, but the material of the side sheet 12 is arbitrary. When the side sheet 12 is attached so as to cover the side gap portion 11, the side surface sheet 12 is formed so as to close substantially the entire area of the side gap portion 11. As shown in FIG. 6, three mounting portions 12a are formed on the upper end portion of the side sheet 12. The mounting portion 12a has a substantially rectangular shape, and a hook-and-loop fastener (not shown) is arranged on the surface thereof. Further, a hook-and-loop fastener (not shown) is also arranged on the outer peripheral surface of the frame-shaped portion 30.

The side sheet 12 is attached to the frame-shaped portion 30 with a hook-and-loop fastener by winding the attaching portion 12a around the frame-shaped portion 30. The side sheet 12 is attached so as to be suspended from the frame-shaped portion 30. A fastener (not shown) is attached to the widthwise end of the side sheet 12. Adjacent side sheets 12 are connected by fasteners as shown in FIG. Therefore, the adjacent side sheets 12 are connected in a state where no gap is formed. A mounting portion (for example, a hook-and-loop fastener) (not shown) is formed on the lower end portion of the side sheet 12, and the side seat 12 is attached to the lower frame portion 20 by the mounting portion. Therefore, the lower end portion of the side sheet 12 is attached so as to come into contact with the lower frame portion 20.

As the side sheet, there is a side sheet 112 having a mesh portion in addition to the side sheet 12 that closes substantially the entire area of the side gap portion 11. When the side sheet 112 is attached so as to cover the side gap 11, as shown in FIG. 7, the side gap 11 may be covered by the mesh portion 112b arranged in a part of the side gap 11. It is possible.

Specifically, as shown in FIG. 8, the side surface sheet 112 is formed with three attachment portions 112a at the upper end portions thereof, similarly to the side surface sheet 12. The mounting portion 112a has a substantially rectangular shape, and a hook-and-loop fastener (not shown) is arranged on the surface thereof.

The side sheet 112 has a rectangular mesh portion 112b and a cover portion 112c that covers the mesh portion 112b. As shown in FIG. 8A, the cover portion 112c faces the mesh portion 112b and covers substantially the entire area of the mesh portion 112b, and as shown in FIG. 8B, does not face the mesh portion 112b. It is possible to take a state in which the mesh portion 112b is wound upward and does not cover substantially the entire area. A fastener (not shown) is attached to the outer peripheral portion of the cover portion 112c, and by opening the fastener and winding the cover portion 112c from the bottom to the top, the state shown in FIG. 8A is shown. It is possible to switch to the state of 8 (b).

FIG. 9 shows a state in which in the indoor tent 1 of FIG. 1, a part of the side sheet 12 attached so as to cover the side gap 11 is replaced with a side sheet 112 having a mesh portion 112b. In the state of FIG. 1, the feeling of shielding inside the tent 1 is relatively high, but in the state of FIG. 9, the cover portion 112c of the side sheet 112 attached to the side surface of the tent 1 is wound from the bottom to the top. Since the mesh portion 112b is not covered in substantially the entire area, the feeling of shielding inside the tent 1 is relatively low. Therefore, the feeling of shielding inside the tent 1 can be adjusted by appropriately replacing the side sheet attached so as to cover the plurality of side gaps 11 with either the side sheet 12 or the side sheet 112. In the indoor tent 1, the mounting position of the completely shielded side sheet 12 and the side sheet 112 having the mesh portion 112b can be arbitrarily changed, and the positions of the entrance portion and the exit portion of the tent 1 can be arbitrarily changed. Therefore, the degree of freedom of the user is improved.

The roof portion 3 always has an opening A that opens upward, as shown in the plan view of the indoor tent 1 of FIG. The opening A communicates the internal space of the tent 1 with the external space above the tent 1.

Since the roof portion 3 has an annular sheet 50 attached to the frame structure 2 and a plurality of short width sheets 60, the size of the opening A is annular from the area of the opening 50a of the annular sheet 50. It is the area obtained by subtracting the total of the areas of the plurality of horizontal frames 32 and the areas of the plurality of short width sheets 60 in the opening 50a of the sheet 50. In the present embodiment, the ratio of the size of the opening A to the size of the installation area of the tent 1 (the size of the lower frame portion 20) shown in the plan view of FIG. 10 is 30% or more.

As described above, since the horizontal frame 33a along the short side direction of the tent 1 is inclined upward from the frame-shaped portion 30, the four short-width sheets 60 arranged between the adjacent horizontal frames 33a Is installed in a vertically displaced state. Therefore, as shown in FIG. 11, when the roof portion 3 of the tent 1 is looked up from the ground, it seems that the opening A is not formed in the roof portion 3.

The method of connecting the frame parts in the frame structure 2 of the indoor tent 1 will be described with reference to FIGS. 12 to 17.

As described above, the frame structure 2 has frame parts that form, for example, 14 vertical columns 10, a frame-shaped portion 30, and a plurality of horizontal frames 32, and by connecting these frame parts, for example, In consideration of assembling the tent 1, it is appropriately divided into a plurality of frame parts.

The frame component included in the frame structure 2 is formed in a cylindrical shape, and the ends of the two frame components are connected to each other in a state of being abutted against each other. The connecting member 80 shown in FIG. 12A is used to connect the two frame components. The connecting member 80 has a first member 81, a second member 82, and two bolts 83.

As shown in FIG. 12B, the first member 81 has a substantially rectangular parallelepiped shape, and extends upward from both ends of the plate-shaped bottom portion 81a arranged below and the bottom portion 81a in the width direction. _{It has two side surface portions 81b, four projecting portions 81c 1} protruding upward from the upper surface of the side surface portion 81b, and two projecting portions 81c ₂ .

The bottom portion 81a is a plate-shaped member and has a substantially rectangular shape. Since both ends of the lower surface of the bottom portion 81a in the width direction are curved, when arranged in a cylindrical frame component, the lower surface of the bottom portion 81a is the inner peripheral surface of the frame component as shown in FIG. 12 (d). It is placed along. The two side surface portions 81b are formed over the entire longitudinal direction of the bottom portion 81a, and a groove portion 81d ₁ is formed between the two side surface portions 81b over the entire longitudinal direction of the bottom portion 81a.

The four protrusions 81c ₁ are arranged at both ends in the longitudinal direction of the two side surface portions 81b, respectively. _{The two protrusions 81c 1} arranged at both ends in the longitudinal direction of the bottom portion 81a are arranged apart in the width direction.

The two protrusions 81c ₂ are arranged at the central portions in the longitudinal direction of the two side surface portions 81b, respectively. On the upper surface of one side surface portion 81b, the protrusions 81c ₂ are arranged between the _{two protrusions 81c 1} arranged at both ends in the longitudinal direction of the bottom portion 81a. Therefore, on the upper surface of one side surface portion 81b, recesses 81d ₂ are formed _{between the protrusions 81c 1} and the protrusions 81c _2.

The second member 82 is a plate-shaped member and has a substantially rectangular shape. _{Wide portions 82a 1} and wide portions 82a ₂ are formed at both ends of the second member 82 in the longitudinal direction, and the wide portions 82a ₁ and 82a ₂ are connected by plate portions 82b. The two wide portions 82a ₁ and 82a ₂ have a substantially rectangular shape, and the width of the two wide portions 82a ₁ and 82a ₂ is larger than the width of the plate portion 82b. The two wide portions 82a ₁ and 82a _{2 have holes 82c 1} and 82c ₂ formed in the central portion thereof, respectively. Threads for bolts 83 are formed on the inner peripheral surfaces of the holes 82c ₁ and 82c _2.

As shown in FIG. 12A, the second member 82 is formed so as to be fitable on the upper surface of the first member 81. In a state where the second member 82 is arranged so as to fit on the upper surface of the first member 81, a slight gap is formed between the first member 81 and the second member 82.

That is, the width of the plate portion 82b is smaller than the width of the groove portion 81d _{1 between the two protruding portions 81c 2 of} the first member 81, and the length of the plate portion 82b is longer than the length of the protruding portion 81c ₂ . .. Further, the widths of the wide portions 82a ₁ and 82a ₂ are substantially the same as the width of the first member 81, and _{the lengths of the wide portions 82a 1} and 82a _{2 are the protrusions 81c 1} and 81c of the first member 81. shorter than the length of the recess 81d ₂ are formed between the _two.

As shown in FIG. 13, the frame structure 2 of the tent 1 is formed by connecting a plurality of frame parts forming, for example, 14 vertical columns 10, a frame-shaped portion 30, and a plurality of horizontal frames 32. The tent 1 uses two types of connection methods, a first connection method and a second connection method, as connection methods for the two frame components. In FIG. 13, the connection points of the frame parts of the portion T are connected by the second connection method, and the connection points of the frame parts other than the part T are connected by the first connection method.

Will be done.

As described above, the frame structure 2 of the tent 1 uses two types of connection methods. When assembling the tent 1, for example, a plurality of frame parts may be assembled upward from the side surface portion of the tent 1.

In that case, the frame parts forming the front surface, the left side surface, the right side surface and the back surface of the tent 1 are connected by the first connection method, and then the frame parts (for example, the horizontal frames 33a and 33b) forming the upper frame portion are formed. (Frame parts) are connected to the frame parts forming the front surface, the left side surface, the right side surface and the back surface of the tent 1 by the first connection method, and then at the center portion in the short side direction of the roof portion 3 of the tent 1. The frame component connected to the left side surface of the tent 1 and the frame component connected to the right side surface are connected.

At that time, if the frame component connected to the left side surface of the tent 1 and the frame component connected to the right side surface are to be connected by the first connection method at the center portion in the short side direction of the roof portion 3 of the tent 1. As described with reference to FIG. 15, the left end portion of the connecting member 80 is temporarily fixed to the end portion of the second frame component 86 in a state of protruding from the end portion of the second frame component 86, and the left end portion of the connecting member 80 is temporarily fixed. It is necessary to abut the end portion of the first frame component 85 against the end portion of the second frame component 86 so that the first frame component 85 is inserted into the first frame component 85.

However, the frame parts forming the front surface, the left side surface, the right side surface and the back surface of the tent 1 and the frame parts forming the upper frame portion (for example, the frame parts forming the horizontal frames 33a and 33b) are connected by the first connection method. When connected, those frame components are connected with high strength. Therefore, in the central portion of the roof portion 3 of the tent 1 in the short side direction, a connection protruding from the end portion of the second frame component 86 is made between the end portion of the first frame component 85 and the end portion of the second frame component 86. It is very difficult to form a gap longer than the length of the left end of the member 80. That is, the first frame component is inserted so that the left end portion of the connecting member 80 is inserted into the first frame component 85 with respect to the end portion of the second frame component 86 in which the left end portion of the connecting member 80 is projected. It is difficult to abut the end of the 85 against the end of the second frame component 86.

Therefore, in the frame structure 2 of the tent 1, the frame parts are connected by the second connection method at the central portion in the short side direction of the roof portion 3 of the tent 1. That is, as described with reference to FIG. 17, a slotted hole portion 186a is formed at the end portion of the second frame component 186, and the left end portion of the connecting member 80 protrudes from the end portion of the second frame component 186. After the connecting member 80 is temporarily fixed to the end of the second frame component 186, the entire connecting member 80 can be moved so as to be arranged in the second frame component 186.

Therefore, in the second connection method, when the end portion of the first frame component 85 is abutted against the end portion of the second frame component 186, the left end portion of the connecting member 80 does not protrude from the end portion of the second frame component 186. It has become. Therefore, as compared with the first connection method, in the central portion in the short side direction of the roof portion 3 of the tent 1, a large gap is provided between the end portion of the first frame component 85 and the end portion of the second frame component 186. The end portion of the first frame component 85 can be abutted against the end portion of the second frame component 186 without being formed.

In the frame structure 2 of the tent 1 of the present embodiment, the tent 1 can be easily assembled by appropriately arranging the connection points for connecting the frame components in the frame structure 2 by the second connection method. In the frame structure 2, the number and arrangement of connection points for connecting the frame components by the second connection method are arbitrary. The shapes of the first member 81 and the second member 82 of the connecting member 80 are arbitrary, and for example, at the center of the lower surface of the bottom portion 81a of the first member 81 in the width direction, as shown in FIG. _{Recesses 81a 1} may be formed over the entire direction.

As described above, the indoor tent 1 of the present embodiment has a plurality of vertical columns 10 formed between the plurality of vertical columns 10, the roof portion 3 arranged above the plurality of vertical columns 10, and the adjacent vertical columns 10.

(Second Embodiment)
The difference between the indoor tent 301 of the present embodiment and the indoor tent 1 of the first embodiment is that the indoor tent 1 has a substantially rectangular shape in a plan view, whereas the indoor tent 301 has a plan view. It is a point that has a substantially octagonal shape.

As shown in FIG. 18, the indoor tent 301 has a substantially octagonal shape in a plan view, and an entrance portion P is formed on a side surface thereof. Hereinafter, the side surface on which the entrance portion P of the tent 1 is formed will be described as the front surface.

As shown in FIG. 19, the frame structure 302 serving as the framework of the tent 301 is arranged above the eight vertical columns 310, the lower frame portion 320 arranged at the lower part of the tent 301, and the upper part of the eight vertical columns 310. It has a frame-shaped portion 330 to be formed, and an upper frame portion 331 arranged above the frame-shaped portion 330.

The eight vertical columns 310 include two vertical columns 310a arranged on both sides of the entrance portion P and six vertical columns 310b arranged at equal intervals between the two vertical columns 310a. There is. The eight vertical columns 310 are arranged so that the upper end thereof is inclined so as to be closer to the central portion of the tent than the lower end. The eight vertical columns 310 all have substantially the same length, and their upper ends are arranged on the same horizontal plane.

The lower frame portion 320 connects the lower portions of the eight vertical columns 310 and has a substantially octagonal shape which is the same as the planar shape of the tent 301. The lower frame 320 is not arranged between the two vertical columns 310a arranged on both sides of the entrance portion P.

The frame-shaped portion 330 connects the upper ends of adjacent vertical columns 310, and has a substantially octagonal shape that is the same as the planar shape of the tent 301. As described above, since the upper ends of the eight vertical columns 310 are arranged on the same horizontal plane, the frame-shaped portion 330 is arranged substantially parallel to the horizontal plane.

The upper frame portion 331 has eight horizontal frames 332. The eight horizontal frames 332 extend from the corners of a substantially octagonal planar shape toward the central portion 335 of the tent 1. _{Each of the eight horizontal frames 332 has a curved portion 332a 1} that extends upward from the frame-shaped portion 330 and then curves in the horizontal direction. In the horizontal frame 332, the portion of the _{tent 301 on the central portion 335 side of the curved portion 332a 1} is substantially linear and is inclined so as to be arranged upward as it approaches the central portion 335 of the tent 301.

The indoor tent 301 has a roof portion 303 arranged on the upper part of the tent 301 and a seat member 312 attached to the side surface of the tent 301.

The roof portion 303 includes a frame-shaped portion 330 included in the frame structure 302, a plurality of horizontal frames 332, an annular sheet 350, and a plurality of short width sheets 360.

The annular sheet 350 is stretched along the frame-shaped portion 330 at the upper part of the tent 301 over the entire circumference thereof. The annular sheet 350 is formed continuously and integrally in an annular shape, and has a substantially octagonal opening 350a.

The annular sheet 350 is arranged on each of the eight side surfaces of the tent 301 so as to extend upward from the outer peripheral portion of the frame-shaped portion 330 and cover _{the curved portion 332a 1 of the horizontal frame 332.}

Regarding the annular sheet 350 in the state of being removed from the frame structure 302, the size of the outer peripheral portion formed in an annular shape is larger than the size of the outer peripheral portion of the frame-shaped portion 330, as in the case of the annular sheet 350 of the first embodiment. It is slightly smaller. Therefore, when the annular sheet 350 is attached to the frame structure 302, the annular sheet 350 is stretched along the frame-shaped portion 330 with an appropriate tension.

The plurality of short width sheets 360 have a rectangular shape having a predetermined width, and are arranged on the upper portion of the tent 301 along the side surface of the tent 301 in a state of being separated from each other. Specifically, two short width sheets 360 are arranged parallel to each other between two adjacent horizontal frames 332. The short width sheet 360 is suspended by a string-shaped member stretched between two adjacent horizontal frames 332. The surface of the short width sheet 360 is arranged parallel to the vertical direction while being suspended from the string-shaped member.

As shown in FIG. 19, a side gap portion 311 is formed between adjacent vertical columns 310 on the side surface of the frame structure 302, but in the indoor tent 301, as shown in FIG. 18, the side gap portion is appropriately formed. A side sheet 312 covering the 311 is attached. In FIG. 19, among the eight side gaps 11 formed between the adjacent vertical columns 10, only the three side gaps 311 arranged on the front side of the tent 301 are designated.

In the frame structure 302 of the indoor tent 301, eight side gaps 311 are formed, and as shown in FIG. 18, the side gaps formed between the two vertical columns 310a arranged in front of the side gaps 311 are formed. The side sheet 312 is not arranged on the 311. Therefore, in front of the indoor tent 301, the internal space and the external space of the tent 301 communicate with each other.

That is, in the indoor tent 1, side sheet 312s covering the respective side gaps 311 are attached to the seven side gaps 311 other than the side gaps 311 formed between the vertical columns 310a arranged in the front. ..

The side sheet 312 has substantially the same size as one side gap 311. When the side sheet 312 is attached so as to cover the side gap 311, the side sheet 312 is formed so as to close substantially the entire area of the side gap 311. The configuration of the side sheet 312 and the method of attaching the side sheet to the frame-shaped portion 330 are the same as those of the side sheet 12 of the first embodiment. Further, as the side sheet, in addition to the side sheet 312 that closes substantially the entire area of the side gap portion 311, there is a side sheet having a mesh portion as in the first embodiment. Therefore, also in the indoor tent 301 of FIG. 18, the feeling of shielding inside the tent 301 can be adjusted by appropriately changing the type of the side sheet.

The roof portion 330 always has an opening A that opens upward, as shown in the plan view of the indoor tent 301 of FIG. The opening A communicates the internal space of the tent 301 with the external space above the tent 301.

Since the roof portion 303 has an annular sheet 350 attached to the frame structure 302 and a plurality of short width sheets 360, the size of the opening A is annular from the area of the opening 350a of the annular sheet 350. It is the area obtained by subtracting the total of the areas of the plurality of horizontal frames 332 and the areas of the plurality of short width sheets 360 in the opening 350a of the sheet 350. In the present embodiment, the ratio of the size of the opening A to the size of the installation area of the tent 301 (the size of the lower frame portion 320) shown in the plan view of FIG. 20 is 30% or more.

A method of connecting frame parts in the frame structure 302 of the indoor tent 301 will be described with reference to FIG.

As described above, the frame structure 302 has frame parts such as eight vertical columns 310, a frame-shaped portion 330, and a plurality of horizontal frames 332. By connecting these frame parts, the tent 301 It is divided into a plurality of frame parts as appropriate in consideration of assembling.

The connecting member 80 described in the first embodiment is used to connect the two frame components.

As shown in FIG. 21, the frame structure 302 of the tent 301 is formed by connecting a plurality of frame components. The tent 301 uses two types of connection methods as the connection method of the two frame parts, and the point is the same as that of the first embodiment. The connection point of the frame component of the portion T of FIG. 21 is the same as that of FIG. 16, and the frame component is connected by the second connection method described in the first embodiment.

As described above, the indoor tent 301 of the present embodiment has a plurality of vertical columns 310, a roof portion 303 arranged above the plurality of vertical columns 310, and a plurality of adjacent vertical columns 310. A side sheet 312 arranged so as to cover at least a part of the side gap 311 is provided, and the roof 303 has an opening A that opens upward.

As a result, the indoor tent 301 of the present embodiment has the same effect as that of the first embodiment.

The specific configuration is not limited to the above-described embodiment.

For example, in the first embodiment, the plurality of short width sheets 60 are attached in parallel to the long side direction of the tent 1, but the arrangement of the plurality of short width sheets 60 is arbitrary. For example, a plurality of short width sheets 60 may be attached parallel to the short side direction of the tent 1. Also, not all short width sheets 60 need to be arranged along the same direction. Further, the number and shape of the plurality of short width sheets 60 are arbitrary. The same applies to the roof portion 303 of the second embodiment.

In the first embodiment, the annular sheet 50 is formed in an annular shape continuously and integrally, but the annular sheet 50 is divided into a plurality of members, and the plurality of members are attached to the outer periphery of the frame-shaped portion 30. By doing so, it may be continuously formed in an annular shape while being attached to the outer periphery of the frame-shaped portion 30. The same applies to the annular sheet 350 of the second embodiment.

In the first embodiment, the indoor tent 1 has a substantially rectangular shape, and in the second embodiment, the indoor tent 301 has a substantially octagonal shape, but the shape of the indoor tent is arbitrary.

In the first embodiment, two types of side sheets 12 and 112 are shown as the side sheets, but the present invention is not limited thereto. For example, the side surface sheets 12 and 112 have substantially the same size as one side gap portion 11, but one side surface sheet may have substantially the same size as the plurality of side gap portions 11.

In the first embodiment, of the 12 side gaps 11, 10 side gaps 11 are covered by the side sheet 12, and the two side gaps 11 are not covered by the side sheet 12. However, the number of side gaps 11 covered by the side sheet 12 and the number of side gaps 11 not covered by the side sheet 12 are arbitrary. That is, the same effect can be obtained in a tent in which at least a part of the 12 side gaps 11 is covered with the side sheet 12. The indoor tent of the present invention includes a side sheet formed so as to be attached so as to cover at least a part of a plurality of side gaps.

In the first embodiment, the roof portion 3 has a frame-shaped portion 30 and a plurality of horizontal frames 32, but the plurality of horizontal frames 32 included in the roof portion 3 include four horizontal frames 33a and 4 It is not limited to the book horizontal frame 33b, the three horizontal frames 34, the two horizontal frames 35, and the two horizontal frames 36. The number, outer diameter, or arrangement of the plurality of horizontal frames 32 included in the roof portion 3 is arbitrary. For example, the roof portion 3 may have a frame-shaped portion 30, but may not have a horizontal frame 32. That is, the effect of the present invention can be obtained when the roof portion arranged above the plurality of vertical columns has an opening that opens upward.

In the first embodiment, the roof portion 3 has an annular sheet 50 and a plurality of short width sheets 60, but is not limited thereto. The same applies to the roof portion 303 of the second embodiment.

For example, as shown in FIG. 22, the roof portion 3 may include the annular sheet 50 and may not include the plurality of short width sheets 60. In that case, the roof portion 3 always has an opening A that opens upward, as shown in the plan view of the indoor tent of FIG. 23. The size of the opening A is the area obtained by subtracting the area of the plurality of horizontal frames 32 in the opening 50a of the annular sheet 50 from the area of the opening 50a of the annular sheet 50. In that case, the ratio of the size of the opening A to the size of the installation area of the tent (the size of the lower frame portion 20) shown in the plan view of FIG. 23 is 30% or more.

Further, as shown in FIG. 24, the roof portion 3 may include a plurality of short width sheets 60 and may not include the annular sheet 50. In that case, the roof portion 3 always has an opening A that opens upward, as shown in the plan view of the indoor tent of FIG. 25. The size of the opening A is the area obtained by subtracting the total of the areas of the plurality of horizontal frames 32 and the areas of the plurality of short width sheets 60 in the frame-shaped portion 30 from the area of the frame-shaped portion 30. In that case, the ratio of the size of the opening A to the size of the installation area of the tent shown in FIG. 25 (the size of the lower frame portion 20) is 30% or more.

Further, as shown in FIG. 26, the roof portion 3 may not include the annular sheet 50 and the plurality of short width sheets 60. In that case, the roof portion 3 always has an opening A that opens upward, as shown in the plan view of the indoor tent of FIG. 27. The size of the opening A is the area obtained by subtracting the area of the plurality of horizontal frames 32 in the frame-shaped portion 30 from the area of the frame-shaped portion 30. In that case, the ratio of the size of the opening A to the size of the installation area of the tent (the size of the lower frame portion 20) shown in FIG. 27 is 30% or more.
