The disclosure of the present invention specifically relates to the following aspects.
[Aspect 1]
A tent sheet, a plurality of poles for supporting the tent sheet, and a plurality of sleeves formed along the surface of the tent sheet corresponding to the plurality of poles and for inserting the plurality of poles. When the plurality of poles are inserted through the plurality of sleeves and the tent is installed on the installation surface, each of the plurality of poles is provided at a plurality of locations on the tent sheet. , Each of the plurality of sleeves intersects the other plurality of poles among the plurality of poles, and the pole is more than each of the other plurality of poles at or around the plurality of poles. A tent provided with a plurality of guiding means for guiding the pole so that the case where the tent sheet intersects on the near side and the case where the tent sheet intersects on the far side are arranged alternately.

In the tent of the first aspect, there is a case where a pole intersects with a plurality of other poles at or around a plurality of positions, and the pole intersects with a side closer to the tent seat than each of the other plurality of poles, and is far from the tent. Each of the plurality of sleeves is provided with a guiding means for guiding the pole so that the case of crossing on the side alternates. In such a tent, when the user assembles the tent, the pole can be easily arranged in a desired positional relationship by the guiding means only by inserting the pole through the sleeve. Then, at that time, the pole can be installed so that the case where the pole intersects on the side closer to the tent seat and the case where the pole intersects on the side farther than each of the other plurality of poles are arranged alternately. That is, a plurality of poles can be alternately combined with each other as upper side / lower side / upper side / lower side / .... As a result, a plurality of poles can be assembled in a high strength state (arrangement as designed) by an easy method of passing the poles through the sleeve. As a result, the strength can be maintained, the safety can be ensured, and the ease of assembly can be satisfied.

[Aspect 2]
The guiding means is formed of two intersecting sleeves that correspond to two intersecting poles, and one of the two intersecting poles is for the two intersecting poles. The tent according to aspect 1, wherein the other of the two poles crossing each other is inserted through one of the sleeves and the other of the two crossing sleeves crossing each other.

In the tent of the second aspect, the guiding means is formed by crossing sleeves corresponding to two crossing poles. Therefore, each of the two poles that intersect each other can be installed on the desired side of the side closer to the tent seat and the side farther from the tent seat, and can be reliably intersected with each other. Therefore, it is possible to satisfy both the maintenance of strength, the assurance of safety, and the ease of assembly.

[Aspect 3]
The guide means is formed of a crossing sleeve corresponding to one of two intersecting poles, and one of the two crossing poles is inserted through the crossing sleeve and said to each other. The tent according to aspect 1, wherein the other of the two intersecting poles is not inserted through the crossing sleeve.

In the tent of the third aspect, the guiding means is formed by a crossing sleeve corresponding to one of two crossing poles. Thereby, one of the two poles intersecting each other is installed on one side of the side closer to the tent seat and the side farther from the tent seat via the crossing sleeve, and the two poles correspondingly intersecting each other. By installing the other of the poles on the outside of the crossing sleeve, on the other side of the side closer to and far from the tent seat, the two poles can be reliably crossed. As a result, it is possible to satisfy both the maintenance of strength, the assurance of safety, and the ease of assembly.

[Aspect 4]
The tent according to aspect 2 or 3, wherein each of the plurality of sleeves is continuously formed on the tent sheet and includes the plurality of the crossing sleeves.

In the tent of the fourth aspect, the plurality of sleeves are continuously formed, including the crossing sleeves. Therefore, when the pole is inserted through the sleeve, the pole can be reliably and appropriately installed on the tent seat without popping out of the sleeve on the way. As a result, it is possible to satisfy both the maintenance of strength, the assurance of safety, and the ease of assembly.

[Aspect 5]
The tent sheet includes a dome portion having a dome shape and a hem portion extending downward from the lower edge of the dome portion, and onto the installation surface of a figure formed at the lower end of the hem portion. The projected area of the dome portion is smaller than the projected area of the figure formed at the lower end of the dome portion onto the installation surface, and the plurality of sleeves are formed from the lower end on one side with respect to the central region of the dome portion to the other side. The tent according to any one of the above aspects 1 to 4, which includes a plurality of first sleeves arranged along the surface of the dome portion up to the lower end of the dome portion.

In the tent of the fifth aspect, since the hem portion is added below the dome-shaped (hemispherical) dome portion, the height inside the tent can be increased by the amount of the hem portion. Thereby, the comfortability in the height direction in the tent can be improved. In addition, the projected area of the figure formed at the lower end of the hem is made smaller than the projected area of the figure formed at the lower end of the dome. Therefore, it is not necessary to expand the installation area of the tent, and restrictions on the installation location can be suppressed. As described above, the tent having the dome portion and the hem portion on the tent sheet has a great advantage, but having the hem portion may be vulnerable to crosswinds and the like. Therefore, in this tent, the poles can be installed by using the guiding means so that the cases where the poles intersect on the side closer to the tent seat and the cases where the poles intersect on the far side than each of the other plurality of poles are arranged alternately. Therefore, a plurality of poles can be installed in a state of high strength, that is, in an arrangement as designed. As a result, it is possible to improve the habitability in the height direction, suppress the increase in the installation area, and maintain the high strength of the tent.

[Aspect 6]
The tent sheet is composed of a plurality of sheet members, each of the plurality of sheet members has a polygonal shape, and the boundary between a plurality of adjacent sheet members among the plurality of sheet members. The line forms a chain boundary line chained from the lower end on one side to the lower end on the other side with respect to the central region of the dome portion, and each of the plurality of first sleeves has a chain boundary line different from each other. The tent according to aspect 5, wherein the guide means of the plurality of first sleeves are arranged along the vertices of the polygon.

In the tent of the sixth aspect, a plurality of boundary lines between adjacent seat members form a chain boundary line in which the dome portion is chained from the lower end on one side to the lower end on the other side, and along the chain boundary line. The first sleeve is arranged. Therefore, the first sleeve tends to be in a state along the chain boundary line, that is, along the side of the polygon. Further, the first sleeve extends along a chain boundary line passing through a plurality of polygons. Here, since adjacent polygons are in contact with each other at vertices, the first sleeve (and tent sheet) on the chain boundary before inserting the first pole tends to be bent before and after such vertices. .. Therefore, the guide means of the plurality of first sleeves are arranged at the vertices of the polygon. By arranging the guiding means at the apex of the polygon, it is difficult for the first sleeve to be bent even before and after the apex, and the first pole is moved along the sides (chain boundaries) of the polygon. It can be inserted through the first sleeve so as to extend. Therefore, when assembling the tent 1, the first pole can be easily inserted through the first sleeve, and the tent can be easily assembled.

[Aspect 7]
The tent according to the sixth aspect, wherein the tent sheet has a spherical polyhedron shape, and the plurality of sheet members constitute each polygonal surface of the spherical polyhedron.

In the tent of the seventh aspect, the tent sheet (dome portion + hem portion) has a spherical polyhedron shape. However, in this case, the portion of the spherical polyhedron corresponding to the upper half of the sphere is a substantially hemispherical dome portion, and the portion corresponding to the lower half of the sphere is the lower side of the substantially hemisphere. Is a hem having a shape cut in a plane parallel to the installation surface. In this case, since the tent sheet is closer to a sphere, the curvature of the surface of the tent sheet when the tent is assembled is almost the same at any position. Therefore, when assembling the tent, when inserting the first pole into the first sleeve, when raising the tent, etc., it is possible to reduce the work of adjusting the condition of the seat member of the tent sheet according to the position of the first sleeve, and the tent can be reduced. It can be assembled more easily.

[Aspect 8]
The tent according to aspect 7, wherein the spherical polyhedron includes an Archimedean solid.

In this aspect 8 tent, the tent sheet (dome portion + hem portion) has an Archimedean solid shape. That is, since the tent sheet is closer to a spherical shape, when assembling the tent, the work of adjusting the condition of the seat member of the tent sheet according to the position of the first sleeve can be further reduced, and the tent can be assembled more easily. ..

[Aspect 9]
The tent according to aspect 8 above, wherein the Archimedean solid contains an icoside decahedron.

In the tent of the ninth aspect, the tent sheet has the shape of an icoside decahedron. That is, it has a shape closer to a sphere than the Archimedean solid. Therefore, when assembling the tent, the work of adjusting the condition of the seat member of the tent sheet according to the position of the first sleeve can be further reduced, and the tent can be assembled more easily.

[Aspect 10]
The tent according to any one of aspects 7 to 9, wherein the plurality of sleeves are arranged along a geodesic line of the tent sheet.

In the tent of aspect 10, a number of sleeves are arranged along the geodesic line of the tent sheet. Thereby, the length of the plurality of poles to be inserted into the plurality of sleeves can be set to the shortest length, and the poles 3 can be more easily inserted into the sleeves 4. Therefore, the time and effort required to install the tent can be reduced, and the tent can be assembled more easily.

Hereinafter, the tent 1 according to the embodiment will be described with reference to the drawings. However, the tent 1 of the present invention is not limited to the configuration of the following embodiment, and can be appropriately combined, substituted, changed, or the like within a range that does not deviate from the purpose and purpose of the present invention.

First, the overall configuration of the tent 1 will be described.
1 to 5 are views showing a configuration example of the tent 1 according to the embodiment. However, FIG. 1 is a perspective view of the tent 1 ((a) is a front view of the tent 1 and (b) is a fly sheet 9), FIG. 2 is a front view of the tent 1, and FIG. 3 is a plan view of the tent 1. FIG. 4 is a bottom view of the tent 1, and FIG. 5 is a schematic view of the inside of the tent 1.

The tent 1 includes a tent sheet 2, a plurality of poles 3, a plurality of sleeves 4, a plurality of tension structures 5, and a separate fly sheet 9. The tent 1 is used by fixing the tent sheet 2, a plurality of poles 3, and the fly sheet 9 to the installation surface G by fixing members 8 and 8'provided at the lower end of the tent 1. However, in the tent 1 (tent sheet 2) installed on the installation surface G, the direction perpendicular to the installation surface G, that is, the bottom B (bottom surface) of the tent 1 is the vertical direction, and the tent 1 is relatively close to the bottom B of the tent 1. The direction is the lower side or the lower side, and the direction relatively close to the top P of the tent 1 is the upper side or the upper side. The method along the surface of the tent 1 is the circumferential direction, and the direction parallel to the installation surface G is the plane direction. Further, viewing the tent 1 downward from the top P side is referred to as a plan view. In another embodiment, it does not include at least one of the tension structure 5 and the fly sheet 9.

The tent sheet 2 is a so-called inner sheet, and is a member that forms a living space of the tent 1. The tent sheet 2 has a substantially spherical shape, which is larger than a hemisphere and smaller than a sphere. That is, the tent sheet 2 has a substantially spherical member having a shape in which the upper hemispherical portion is left as it is and the lower portion of the lower hemispherical portion is cut in a plane parallel to the installation surface G. There is. In other words, the tent sheet 2 has a shape similar to a ball cap having a first solid angle having a solid angle larger than 2π steradian and smaller than 4π steradian, with the position where the solid angle is 0 as the top, and the first solid angle. It has a shape with the position at the bottom. The bottom surface of the tent sheet 2 is covered with a sheet-shaped bottom portion B. The tent sheet 2 also has a window 7, an entrance / exit D, a ventilator (not shown), a pocket (not shown), and the like.

The substantially spherical shape of the tent sheet 2 is based on the shape of the icoside decahedron (quasi-regular dodecahedron or dodecahedron). ICOSIDODECAHEDRON includes dodecahedrons of regular pentagons and icosahedrons of equilateral triangles. The substantially spherical shape of the tent sheet 2 is a virtual surface parallel to the bottom surface of the lower hemispherical portion of the lower hemispherical portion having a predetermined thickness in the icoside decahedron arranged with a regular pentagon as the top surface and the bottom surface. It has a shape cut by. However, the virtual surface is a plane connecting the vertices of a regular polygon, for example, a surface passing through a position of about 1/5 of the total height from the bottom surface. The upper hemisphere contains six regular pentagons and ten regular triangles, and the lower part contains five partially cut regular pentagons and five regular triangles. There is. The shape based on the shape of the dodecahedron is preferable in that it is close to the shape of a sphere, and therefore, for example, the ratio of the surface area to the volume is small. In addition, it can be said that the icoside decahedron is a geodesic polyhedron formed by a polygon having a geodesic line as a part of a great circle of a sphere as an edge. In another embodiment, the substantially spherical shape of the tent sheet 2 is an archimedean solid or a quasi-regular polyhedron, and in yet another embodiment, the apex of the polyhedron is a spherical polyhedron inscribed in a sphere.

The tent sheet 2 includes a dome portion 11 and a hem portion 12. The dome portion 11 is a portion of the tent sheet 2 having a dome shape, that is, an upper hemispherical portion of a substantially spherical member. The dome portion 11 includes six faces of a regular pentagon and ten faces of an equilateral triangle. Hereinafter, the surface parallel to the installation surface G formed by the lower end edge of the dome portion 11 is also referred to as an equatorial surface E. The equatorial plane E can be said to be the boundary surface between the dome portion 11 and the hem portion 12. The hem portion 12 is a portion of the tent sheet 2 extending downward from the lower end edge of the dome portion 11, is a lower hemispherical portion of a substantially spherical member, and the lower portion thereof is an installation surface. It is a shape cut in a plane parallel to. The hem portion 12 includes five faces of a partially cut regular pentagon and five faces of an equilateral triangle. However, the shape of the dome portion 11 and the hem portion 12 allows a slight deviation in dimensions (example: ± 5%) in consideration of the manufacturing yield. In another embodiment, the tent sheet 2 does not include a dome portion 11 and a hem portion 12.

As shown in FIG. 4, the projected area of the installation surface G at the bottom B is a figure formed by the lower edge of skirt 12 S _B is the equatorial plane E is a figure formed by the lower edge of the dome portion 11 smaller than the projected area S _E to the installation surface G in. S _B is preferably not more than 60% to 95% of _{S E,} more preferably 85% or less 70% of the _{S E.} If it is too large, the effect of the hem 12 (described later) cannot be obtained, and if it is too small, the living section becomes narrow. Therefore, in the tent 1, it can be said that the outer edge of the hem portion 12 is located inside the outer edge of the dome portion 11 in a plan view. The shape of the bottom B is originally a regular pentagon, but it is made a nonagon by shifting the midpoints of the four sides excluding one side of the entrance portion of the five sides of the regular pentagon to the outside. As a result, the bottom B is widened to improve the comfort in the plane direction.

As shown in FIG. 5, the range of the contact angle α formed by the side surface W of the hem portion 12 and the installation surface G is larger than 90 degrees and smaller than 180 degrees. α is preferably greater than 95 degrees and less than 135 degrees, more preferably greater than 95 degrees and less than 120 degrees. If it is too small, the effect of the hem 12 (described later) cannot be obtained, and if it is too large, the living section becomes narrow. Therefore, the hem portion 12, which is the lower portion of the tent sheet 2, has a shape that is narrowed downward, that is, toward the bottom portion B. In other words, in the tent 1, the side surface W extends outward at the hem 12 from the bottom surface (bottom B) of the tent 1 toward the boundary with the dome 11 (equatorial surface E), and the hem 11 at the dome 11. The shape shrinks inward from the boundary (equatorial plane) between the 12 and the dome portion 11 toward the ceiling (top P). Therefore, the projected figure of the bottom portion B formed at the lower end of the dome portion 11 on the installation surface G includes the projected figure of the equatorial plane E formed at the lower end of the hem portion 12 on the installation surface G inside.

Each sleeve 4 is a sleeve-shaped or tubular member through which the pole 3 is inserted, and is arranged (joined) along the surface of the tent sheet 2 corresponding to the position where the pole 3 is arranged. One pole 3 is inserted through one sleeve 4. Therefore, the arrangement of the sleeve 4 projected on the surface of the tent sheet 2 substantially overlaps with the arrangement of the poles projected on the surface of the tent sheet 2.

The plurality of sleeves 4 includes a plurality of first sleeves 4a and at least one second sleeve 4b. The first sleeve 4a is provided on the surface of the dome portion 11 so as to follow the surface of the dome portion 11 from the lower end portion on one side of the dome portion 11 to the lower end portion on the other side with respect to the central region of the dome portion 11. It is arranged (joined). The lower end of one side of the dome portion 11 is located, for example, on the equatorial plane E or near the equatorial plane E, and the lower end of the other side is opposite to the one end of the dome portion 11 with the central region of the dome portion 11 in between. It is located on or near the equatorial plane E on the side, and both have an opening into which the pole 3 can be inserted. The first sleeve 4a intersects the equatorial plane E at an angle greater than 0 degrees and less than 180 degrees. However, the central region of the dome portion 11 is the central portion of the equatorial plane E inside the dome portion 11. The second sleeve 4b is a sleeve 4 other than the first sleeve 4a. The second sleeve 4b is arranged (joined) on the surface of the dome portion 11 so as to surround the equatorial plane E except for the vicinity of the entrance / exit D of the tent 1 and along the surface of the dome portion 11. The second sleeve 4b is arranged parallel to the equatorial plane E (without intersecting the equatorial plane E).

Of the sleeves 4, the first sleeve 4a is continuously provided so that the pole 3 does not protrude out of the first sleeve 4a during the insertion work, so that the pole 3 to be inserted is continuously covered. It is formed. As a result, when assembling the tent 1, the pole 3 can be inserted at once from one end of the first sleeve 4a of the two-dimensionally expanded tent sheet 2 to the other end. On the other hand, of the sleeves 4, the second sleeve 4b is formed intermittently so that the poles 3 are exposed in places. As a result, when the tent 1 is assembled, the tent sheet 2 is formed in a three-dimensional substantially spherical shape by a plurality of first poles 3a inserted through the plurality of first sleeves 4a, and the equatorial plane E is formed in a tense state. This is to make it easier for the user to assist the pole 3 by hand when inserting the pole 3 into the second sleeve 4b. In another embodiment, the first sleeve 4a may be formed intermittently or the second sleeve 4b may be formed continuously.

The plurality of poles 3 are members for supporting the tent sheet 2, and are used by being inserted into the plurality of sleeves 4. By stretching the plurality of poles 3 inserted through the plurality of sleeves 4 on the installation surface G, the plurality of poles 3 can support the tent sheet 2 via the plurality of sleeves 4. As described above, one pole 3 is inserted into one sleeve 4. Each of the plurality of poles 3 is formed so as to be disassembleable or foldable.

The plurality of poles 3 include a plurality of first poles 3a and at least one second pole 3b. The first pole 3a is inserted into the first sleeve 4a formed in the dome portion 11. The portion of the first pole 3a on the dome portion 11 side is inserted through the first sleeve 4a so as to follow the surface of the dome portion 11 from the lower end portion on one side of the dome portion 11 to the lower end portion on the other side. Be placed. On the other hand, the portion of the first pole 3a on the hem 12 side extends along the surface of the hem 12 from the lower ends of the dome portion 11 on one side and the other end to the installation surface G. It reaches G and is fixed to the installation surface G by the fixing member 8. The portion of the first pole 3a extending along the surface of the hem portion 12 is joined to the surface of the hem portion 12 by a hook or the like. The first pole 3a intersects the equatorial plane E at an angle larger than 0 degrees and smaller than 180 degrees on the surfaces of the dome portion 11 and the hem portion 12. The second pole 3b is inserted into the second sleeve 4b formed along the equatorial plane E of the dome portion 11. The second pole 3b is inserted through the second sleeve 4b, surrounds the equatorial plane E except for the vicinity of the entrance / exit D of the tent 1, and is located along the surface of the dome portion 11. The second pole 3b does not intersect the equatorial plane E and is parallel to the surface of the dome portion 11.

The fly sheet 9 is not particularly limited as long as it can cover a substantially spherical structure formed by a tent sheet 2, a plurality of poles 3, a plurality of sleeves 4, and a plurality of tension structures 5. For example, a substantially spherical sheet formed so as to inscribe the substantially spherical structure can be mentioned.

The material of the tent sheet 2 and the fly sheet 9 is not particularly limited as long as it can be used as the tent sheet or the fly sheet, and examples thereof include various nylons and synthetic resins such as tetron and polyester. The material of the pole 3 is not particularly limited as long as it can be used as the material of the pole, but for example, a composite material such as carbon fiber or fiber reinforced plastic, a metal such as duralumin (aluminum alloy), steel or stainless steel, etc. Can be mentioned. The material of the sleeve 4 is not particularly limited as long as it can be used as a sleeve, but for example, a material similar to the material of the tent sheet can be used. The surface of each material may be appropriately processed.

FIG. 6 is a front view showing a configuration example of the tent sheet 2 according to the embodiment. The tent sheet 2 is composed of a plurality of sheet members 21. Since the substantially spherical shape of the tent sheet 2 is based on the quasi-regular thirty o'clock surface, the shapes of the plurality of seat members 21 have polygonal shapes (regular pentagon and regular triangle). Adjacent sheet members 21 are joined to each other by a joining portion (not shown) so as to share sides and vertices. Examples of the joining method include suturing, adhesion, and fusion. The joints between the adjacent sheet members 21 form a boundary line 22 between the adjacent sheet members 21. The plurality of boundary lines 22 are chained along the circumferential direction from the lower end portion on one side to the lower end portion on the other side with respect to the central region of the dome portion 11 to form the chain boundary line 23. However, chaining means that one end of a boundary line connects to one end of the next boundary line, the other end of the next boundary line connects to one end of the next boundary line, and so on. A state in which wires are lined up in series and the ends are joined together. The plurality of sleeves 4 are arranged along the plurality of chain boundary lines 23. In another embodiment, the shape of the sheet member 21 is at least partly a shape other than a polygon, and in yet another embodiment, the tent sheet 2 is not composed of a plurality of sheet members 21, and is a single sheet. It is composed of members.

Specifically, the plurality of seat members 21 include a seat member 21a having a regular pentagonal shape and a seat member 21b having an equilateral triangular shape. The dome portion 11 has six regular pentagonal seat members 21a and ten regular triangular seat members 21b. Further, the hem portion 12 has five faces of a partially cut regular pentagonal seat member 21a'and five faces of an equilateral triangular seat member 21b. Of these, a plurality of first boundary lines 22a, which are boundary lines 22 that intersect the equatorial plane E or extend away from the equatorial plane E, are chained to form the first chain boundary line 23a. On the other hand, a plurality of second boundary lines 22b, which are boundary lines 22 extending along the equatorial plane E, are chained to form a second chain boundary line 23b. At this time, since the substantially spherical shape of the tent sheet 2 is based on the quasi-regular dodecahedron, the chain boundary line 23, that is, the first chain boundary line 23a and the second chain boundary line 23b is a great circle of the icoside decahedron. It corresponds to the geodesic line (the shortest distance line on the curved surface).

However, the shape of the plurality of seat members 21 refers to a joint portion in the seat member 21, that is, a shape formed (or bordered) by a boundary line. Therefore, for example, when the shape of the sheet member 21 is polygonal, it means that the shape of the sheet member 21 formed (or bordered) by the boundary line (joint portion) is polygonal. Further, when the plurality of sheet members 21 have a polygonal shape, it does not necessarily have to be a strict polygon, and may be substantially a polygon. The substantially polygon includes, for example, a polygon in which each side of the polygon of each sheet member 21 is bulged so as to be gently convex outward so as to bring the tent sheet 2 closer to the shape of a sphere. Therefore, it includes a polygon in which the sum of the internal angles is 180 degrees or more. In the case of the present embodiment, the tent sheet 2 has a shape based on the icoside decahedron (quasi-regular dodecahedron), but has a shape closer to a sphere. Further, the sheet member 21 may include a slight dimensional deviation (example: ± 5%) in consideration of the manufacturing yield.

FIG. 7 is a front view showing a configuration example of the sleeve 4 according to the embodiment. This figure shows a configuration in which a plurality of sleeves 4 and a plurality of poles 3 are added to the tent sheet 2 of FIG. 6, that is, a configuration in which the tension structure 5 is excluded in FIG. 2 is shown. Each of the plurality of sleeves 4 is arranged along a plurality of boundary lines 22, that is, a chain boundary line 23. Each chain boundary line 23 is a part of the great circle of the icoside decahedron and corresponds to a geodesic line. Therefore, it can be said that the plurality of sleeves 4 and the plurality of poles 3 are arranged along the great circle portion of the tent sheet 2 or the geodesic line.

The plurality of first poles 3a inserted through the plurality of first sleeves 4a are arranged along the plurality of first chain boundary lines 23a. Since the plurality of first chain boundary lines 23a are formed along geodesics having the same length as each other, they have the same length. On the other hand, the second pole 3b inserted through the second sleeve 4b is arranged along the second chain boundary line 23b. The second chain boundary line 23b is formed along the geodesic line of the equatorial plane E, but since the geodesic line is longer than the geodesic line along the first chain boundary line 23a, the second chain boundary line 23b is the second. It is longer than the one-chain boundary line 23a.

Next, the guidance means will be described. The tent 1 is provided with a plurality of guiding means.
FIG. 8 is a perspective view showing a configuration example of the guide means 41 according to the embodiment. However, in this figure, the description of the tension structure 5 is omitted. In the tent 1, each of the plurality of poles 3 intersects with the other plurality of poles 3 at a plurality of points on the tent sheet 2. Here, the strength of the tent 1 against wind and the like changes depending on whether one pole intersects the upper side or the lower side of each of the other plurality of poles 3 at the plurality of places or around them. .. Therefore, in the present embodiment, as a preferred embodiment, in each of the plurality of sleeves 4 of the tent 1, a plurality of guides for guiding the intersection of the pole 3 and / or other poles 3 at or around the plurality of sleeves 4 of the tent 1. The means 41 is provided. Specifically, when the predetermined pole 3 should pass the upper side of the other pole 3, the guiding means 41 passes the predetermined pole 3 on the upper side and the other pole 3 passes on the lower side of both poles 3. Guide. On the other hand, when the predetermined pole 3 should pass the lower side of the other pole 3, the guiding means 41 guides both poles 3 so that the predetermined pole 3 passes the lower side and the other pole 3 passes the upper side. To do. In this way, the tent 1 can exhibit the strength as designed by crossing the plurality of poles 3 as designed by providing the plurality of guiding means 41 on each of the plurality of sleeves 4, and is safe. Can be secured. In particular, in the present embodiment, the plurality of guiding means 41 pass through the side closer to the tent sheet 2 than the other poles 3 (under the other poles 3) in any pole 3. A plurality of poles 3 are guided so that the case of crossing and the case of crossing so as to pass through a distant side (further upper side of another pole 3) are arranged alternately.

As shown in FIG. 8, the guide means 41 _U1 of the guide means 41 has two intersecting sleeves 4q-1 corresponding to 3-1 and 3-2 on two poles intersecting each other. It is made of 4q-2. _{The guide means 41 D1} of the guide means 41 is formed of two intersecting sleeves 4q-1 and 4q-3 corresponding to two poles 3-1 and 3-3 that intersect each other. ..

In the guiding means 41 _U1 , one pole 3-1 of the two crossing poles 3 is one of the two crossing sleeves 4q crossing each other, the crossing sleeve 4q-1 passing above. The other pole 3-2 of the two poles 3 that are inserted into and intersect each other is the other of the two crossing sleeves 4q that intersect each other, the crossing sleeve 4q-2 that passes underneath. It has been inserted. On the other hand, in the guiding means 41 _D1 , the pole 3-1 which is one of the two poles 3 which intersect with each other is one of the two crossing sleeves 4q which intersect with each other, and is for crossing passing through the lower side. The other pole 3-2 of the two poles 3 inserted through the sleeve 4q-1 and intersecting each other is the other of the two intersecting sleeves 4q intersecting each other, the crossing sleeve 4q passing above. It is inserted in -2. Therefore, in the guide means 41 _U1 and the guide means 41 _D1 , when the pole 3-1 intersects so as to pass the side farther from the tent sheet 2 than the other pole 3-2, and when the pole 3-1 crosses the other pole 3 The pole 3-1 is guided so that the cases where the tent sheet 2 is closer to the tent sheet 2 than the -3 are alternately arranged.

In such a tent 1, the guide means 41 _U1 and 41 _D1 make each of the two poles 3-1, 3-2, 3-1 and 3-3 intersecting each other closer to and farther from the tent sheet 2. It can be installed on the desired side of the sides to ensure that they intersect each other. As a result, a plurality of poles 3 can be arranged like a plain weave, and the strength of the tent 1 can be maintained, safety can be ensured, and ease of assembly can be satisfied.

FIG. 9 is a perspective view showing another configuration example of the guiding means 41 according to the embodiment. However, in this figure, the description of the tension structure 5 is omitted. The guiding means 41 _U2 of the guiding means 41 is formed by a crossing sleeve 4q-2 corresponding to a pole 3-2 which is one of two poles 3-1 and 3-2 intersecting with each other. .. The guiding means 41 _D2 of the guiding means 41 is formed by a crossing sleeve 4q-1 corresponding to a pole 3-1 which is one of two poles 3-1 and 3-3 intersecting with each other. ..

In the guiding means 41 _U2 , one pole 3-2 of the two poles 3 intersecting with each other is inserted into the crossing sleeve 4q-2 passing under the pole 3-1 and the two poles intersecting each other. The other pole 3-1 of the poles 3 is not inserted through the crossing sleeve 4q. On the other hand, in the guiding means 41 _D2 , one pole 3-1 of the two poles 3 intersecting with each other is inserted into the crossing sleeve 4q-1 passing under the pole 3-3 and intersects with each other. The other pole 3-3 of the book pole 3 is not inserted through the crossing sleeve 4q. Therefore, in the guide means 41 _U2 and the guide means 41 _D2 , when the pole 3-1 intersects so as to pass the side farther from the tent sheet 2 than the other pole 3-2, and when the pole 3-1 crosses the other pole 3 The pole 3-1 is guided so that the cases where the tent sheet 2 is closer to the tent sheet 2 than the -3 are alternately arranged.

In such a tent 1, the guide means 41 _U2 and 41 _D2 make each of the two poles 3-1, 3-2 and 3-1 and 3-3 intersecting each other closer to and farther from the tent sheet 2. It can be installed on the desired side of the sides to ensure that they intersect each other. As a result, a plurality of poles 3 can be arranged like a plain weave, and the strength of the tent 1 can be maintained, safety can be ensured, and ease of assembly can be satisfied.

Next, the method of assembling the tent 1 in the present embodiment is as follows.
(1) Unfold the folded tent sheet 2 on the installation surface G. At this time, the dome portion 11 is on the upper side and the hem portion 12 is on the lower side. That is, the plurality of sleeves 4 on the dome portion 11 are exposed on the upper side, and the hem portion 12 is substantially hidden on the lower side.
(2) A plurality of first poles 3a are inserted into the plurality of first sleeves 4a of the tent sheet 2. At this time, one first pole 3a is inserted for each first sleeve 4a so that both ends of the first pole 3a protrude on both sides of the dome portion 11 with the first sleeve 4a interposed therebetween. FIG. 10 is a perspective view showing a state of the step (2) of the state in the process of assembling the tent 1.
(3) The dome portion 11 is made hemispherical by erecting the plurality of first poles 3a while holding both ends of the plurality of first poles 3a. Then, both ends of the plurality of first poles 3a are attached to the plurality of hooks and the plurality of fixing members 8 attached to the hem portion 12.
(4) The second pole 3b is communicated with the second sleeve 4b. If necessary, cover the whole with a fly sheet 9.
The tent 1 is assembled by the above method.

As described above, in the present tent 1, each of the plurality of sleeves 4 is provided with the guiding means 41 (41 _U1 , 41 _D1 / 41 _U2 , 41 _D2 ) for guiding the pole 3, so that when the user assembles the tent 1. By simply inserting the pole 3 through the sleeve 4, the guide means 41 can easily arrange the pole 3 and the plurality of other poles 3 in a desired positional relationship. In particular, for each of the plurality of poles 3, the case where the pole 3 intersects on the side closer to the tent sheet 2 and the case where the pole 3 intersects on the side farther than each of the other plurality of poles 3 are arranged alternately. Pole 3 can be installed. That is, a plurality of poles can be alternately combined with each other as upper side / lower side / upper side / lower side / .... Thereby, a plurality of poles 3 can be assembled in a high strength state (arrangement as designed) by an easy method of passing the poles through the sleeve. As a result, the tent 1 can maintain strength, ensure safety, and be easy to assemble. In other words, if the plurality of poles 3 are expanded into a two-dimensional plane and the angle of intersection of the plurality of poles 3 in the plane is 90 degrees, the plurality of combined poles 3 will be combined. It can be said that they are combined like a plain weave. As a result, the strength of the assembled structure can be increased without increasing the number of poles 3.

In the present embodiment, as a preferred embodiment, the plurality of crossing sleeves 4q are included in the plurality of sleeves 4 continuously formed on the tent sheet 2. Therefore, when the pole 3 is inserted into the sleeve 4, the pole 3 can be reliably and appropriately installed on the tent sheet 2 without popping out from the sleeve 4 on the way, and a plurality of poles 3 can be installed in a high-strength arrangement. It is possible to satisfy both the maintenance of strength, the assurance of safety, and the ease of assembly.

In the present embodiment, as a preferred embodiment, a plurality of boundary lines 22 between adjacent seat members 21 form a chain boundary line 23 in which the dome portion 11 is chained from the lower end on one side to the lower end on the other side. , The first sleeve 4a is arranged along the chain boundary line 23. Therefore, the first sleeve 4a tends to be in a state along the chain boundary line 23, that is, along the side of the polygon. Further, the first sleeve 4a extends along the chain boundary line 23 passing through the plurality of polygons. Since the adjacent polygons are in contact with each other at the vertices, the first sleeve 4a (and the tent sheet 2) on the chain boundary line 23 before the first pole 3a is inserted is bent before and after such a vertex. It is easy to get into a state. Therefore, the guide means 41 of the plurality of first sleeves 4a are arranged at the vertices of the polygon. By arranging the guiding means 41 at the apex of the polygon, it is difficult for the first sleeve 4a to be in a bent state even before and after the apex, and the first pole 3a is set on the sides of a plurality of polygons (chain boundary line 23). It can be inserted into the first sleeve 4a so as to extend along the line. Therefore, when assembling the tent 1, the first pole 3a can be easily inserted through the first sleeve 4a, and the tent can be easily assembled.

In the present embodiment, as a preferred embodiment, in the tent 1, since the hem portion 12 is added below the dome-shaped (hemispherical) dome portion 11, the height inside the tent 1 can be increased by the amount of the hem portion 12. .. As a result, as shown in FIG. 5, the living space in the height direction (direction between the bottom B and the top P) in the tent 1 can be increased, such that the user M1 can stand up in the tent 1. Moreover, the projected area S _B of the installation surface G of the bottom B, and smaller than the projected area S _E to the installation surface G of the equatorial plane E. Thus, the footprint (approximately equivalent to S _E) above it is not necessary to expand the footprint of the tent 1 of the dome portion 11, that is, requires the same footprint as tent only dome portion (conventional dome tent) , It is possible to suppress restrictions on the installation location. That is, it is possible to suppress an increase in the installation area while increasing the living space in the height direction. For example, when the diameter is 3 m, the ceiling height of the conventional dome-shaped tent is about 1.5 m, but that of the main tent 1 is about 2.1 m. That is, the ceiling height can be increased by about 40% without increasing the installation area. Further, in the present tent 1, a plurality of first sleeves 4a are arranged from the lower end portion on one side to the lower end portion on the other side of the dome portion 11, but are not arranged on the hem portion 12. Therefore, the plurality of first poles 3a of the plurality of poles 3 can be easily inserted into the plurality of first sleeves 4a. The tent sheet 2 of FIG. 10 shows a state in which a plurality of first poles 3a are inserted into the plurality of first sleeves 4a on the dome portion 11. Thereby, after that, both ends of each of the plurality of first poles 3a can be erected, and the tent 1 can be easily assembled as shown in FIG. 10 (a). That is, the tent 1 can be easily assembled while increasing the living space in the height direction. In this way, it is possible to obtain the main tent 1 having a comfortable space in which people can stand and work inside, such as a living room of a house, instead of the conventional tent that only sleeps in a sleeping bag. And, for example, even a general family who enjoys auto camp casually can easily assemble the original book tent 1. Thereby, a tent having excellent comfort, compactness and ease of assembly can be obtained.

In the present embodiment, as a preferred embodiment, as shown in FIG. 5, the range of the contact angle α formed by the side surface W of the hem portion 12 and the installation surface G is larger than 90 degrees and smaller than 180 degrees.
In such a tent 1, the lower portion of the tent sheet 2, that is, the hem portion 12, has a shape that narrows toward the lower side. That is, inside the tent 1, the side surface W extends outward at the hem 12 from the bottom surface (bottom B) of the tent 1 toward the boundary with the dome 11 (equatorial surface E), and the hem at the dome 11. The shape is narrowed inward from the boundary (equatorial plane E) between the portion 12 and the dome portion 11 toward the ceiling (top P). Therefore, even when the user M2 sits near the side surface W of the tent 1 inside the tent 1, the user M2 presses the head as compared with the tent having only the dome portion (conventional dome-shaped tent). It can be suppressed. As a result, it is possible to increase the living space in the plane direction when the user M2 is seated. That is, the living space in the plane direction can be increased to improve the livability.

As described above, the tent 1 having the dome portion 11 and the hem portion 12 on the tent sheet 2 has a great advantage, but having the hem portion 12 may be vulnerable to crosswinds and the like. Therefore, as a preferred embodiment in the present embodiment, in the tent 1, the poles 3 intersect on the side closer to the tent sheet 2 (lower side) and on the far side (upper side) than each of the other plurality of poles 3. Since the poles 3 can be installed by using the guide means 41 so that the cases of the above are alternately arranged, the plurality of poles 3 can be installed in a state of high strength, for example, in an arrangement as designed. As a result, it is possible to maintain a high strength state of the tent 1 while having the advantages of improving the habitability in the height direction and suppressing an increase in the installation area.

Further, as a preferred embodiment in the present embodiment, in the tent 1, the tent sheet 2 has the shape of an icoside decahedron (however, the shape in which the lower portion is partially removed, the same applies hereinafter). In another embodiment, in the tent 1, the tent sheet 2 may have the shape of a polyhedron, in particular a spherical polyhedron in which the vertices of the polygons constituting the polyhedron are inscribed in the sphere (having an circumscribed sphere). It may have the shape of a semi-regular polyhedron, or it may have the shape of an archimedean solid or a quasi-regular polyhedron. In these cases as well, in this case, since the tent sheet 2 is closer to a spherical shape, the curvature of the surface of the tent sheet 2 when the tent 1 is assembled is substantially the same at any position. Therefore, when assembling the tent 1, the condition of the seat member 21 of the tent sheet 2 is adjusted by the position of the first sleeve 4a when the first pole 3a is inserted into the first sleeve 4a or when the tent 1 is started up. The work to be done can be reduced, and the tent 1 can be assembled more easily. In a strict sense, the tent sheet 2 does not have to have the shape of these spherical polyhedrons or archimedean solids (archimedean polyhedron, quasi-regular polyhedron, quasi-regular dodecahedron (including icoside decahedron)). It suffices to have the shape of a substantially spherical polyhedron or a substantially archimedean solid, that is, a substantially spherical polyhedron or an archimedean solid. Substantially having those shapes means that each side is rounded and curved, or each surface is rounded and curved, and the like is included.

Further, as a preferred embodiment in the present embodiment, the plurality of sleeves 4 are arranged along the geodesic line of the tent sheet 2. Thereby, the length of the plurality of poles 3 inserted through the plurality of sleeves 4 can be set to the shortest length, and the poles 3 can be more easily inserted into the sleeves 4. Therefore, the time and labor required to install the tent 1 can be reduced, and the tent 1 can be assembled more easily.

Next, the tension structure 5 will be described. In the present embodiment, as a preferred embodiment, the tent 1 further includes a tension structure 5. 11 to 13 are diagrams showing a configuration example of the tension structure 5 according to the embodiment. However, FIG. 11 is a perspective view showing a configuration example of the tension structure 5 of the tent 1, FIG. 12 is a schematic view showing another configuration example of the tension structure 5, and FIG. 13 shows the operation of the tension structure 5. It is a schematic diagram.

As shown in FIGS. 11 and 2 to 3, the tent sheet 2 has a plurality of first regions R partitioned within the tent sheet 2. Each of the plurality of first regions R is a region in the tent sheet 2 that is partitioned by a plurality of compartment poles 3p, which are some poles 3 of the plurality of poles 3, and does not include other poles 3 inside. .. It is also a region that is partitioned by a plurality of compartment sleeves 4p through which a plurality of compartment poles 3p are inserted and does not include other sleeves 4 inside. The first region R corresponds to the regular pentagonal region (of the icoside decahedron) of the seat member 21.

The tent 1 includes a tension structure 5 in the first region R. The tension structure 5 improves the load capacity of the tent 1 by distributing the load generated in the first region R to the surrounding configuration, for example, the partition pole 3p. The tension structure 5 divides the first region R into a plurality of tension regions A. Therefore, the tension structure 5 disperses the load generated in the first region R into a plurality of tension regions A, and further disperses the load generated in the first region R from the plurality of tension regions A to the surrounding configuration, for example, the partition pole 3p in contact with the plurality of tension regions A. By doing so, it can be said that the load capacity of the tent 1 is improved. The tension structure 5 is provided inside the tent sheet 2 in the first region R of the top portion P. The tension structure 5 of the top P pushes up the top P from the inside to the outside inside the tent sheet 2. In this case, the support member 51 is located inside the tent sheet 2. In another embodiment, the support member 51 may penetrate the tent sheet 2 at the top P and extend outward. The tension structure 5 of the top P may be outside the tent sheet 2.

The tension structure 5 includes a plurality of linear members 52 and a support member 51. Each of the plurality of linear members 52 is a linear member such as a wire or a string, one end of which is connected to at least one partition pole 3p and the other end of which is connected to a support member 51. The position where the linear member 52 is connected in the compartment pole 3p is the position where the two compartment poles 3p intersect, which corresponds to the position of the apex of the regular pentagon of the seat member 21. In another embodiment, the position where the linear member 52 is connected in the partition pole 3p is a position in the middle (example: center) of each side of the regular pentagon. The support member 51 is located in the first region R, for example, on the surface of the tent sheet 2 in the first region R, and has a predetermined height (thickness) with respect to the surface of the tent sheet 2. It is a member to have. The support member 51 is preferably arranged at the center of gravity of the regular polygon in the first region R. The support member 51 is preferably arranged at a balanced position where the forces applied to the plurality of linear members 52 are balanced. At this time, the support member 51 is placed on the surface of the tent sheet 2 without being joined, and is supported (held) at a balanced position by a plurality of linear members 52. In another embodiment, the support member 51 is arranged at the center of gravity of the regular polygon in the first region R, and in yet another embodiment, the support member 51 is joined to the surface of the tent sheet 2. However, the coupling includes not only the case where the members are joined (joined) in a state of being in direct contact with each other, but also the case where the members are indirectly joined via another member such as a ring member. In this case, one end of the linear member 52 is connected to the partition pole 3p via the ring member 53. That is, the linear member 52 is joined to the ring member 53 in a state where the partition pole 3p penetrates through the ring.

The first region R surrounded by the plurality of partition poles 3p is divided into a plurality of tension regions A by the plurality of linear members 52 of the tension structure 5. The tension region A can be seen as a triangular region surrounded by two adjacent linear members 52 having the other ends joined to the support member 51 and one partition pole 3p. In such a triangular region, even if a force is applied to the support member 51 which is the apex of the triangle, the force can be dispersed to the two linear members 52 which are the left and right sides. The dispersed force is received by the compartment pole 3p.

For example, in the example shown in FIG. 12, when viewed in a plane substantially parallel to the surface of the first region R, the first region R of a regular pentagon is divided into five triangular tension regions A _{11 to} A ₁₅ . That is, the five tension regions A _{11 to} A ₁₅ are all triangular members surrounded by two adjacent linear members 52 having the other ends joined to the support member 51 and one partition pole 3p. The area. Therefore, load is applied such as wind in the first region R of the tent sheet 2, even when a load is applied K ₁₀ to the support member 51 are the vertices of the triangle, which is right and left sides of the five triangle the load K ₁₀ five The loads can be _{K 11 to} K ₁₅ by being dispersed in the linear members 52 of the book. The distributed loads K _{11 to} K ₁₅ are each received by a plurality of compartment poles 3p. That is, the tension (example: linear member 52) and the compression (example: partition pole 3p) can be integrated in a well-balanced manner, and the load K ₁₀ can be dispersed in a well-balanced manner. As a result, the tent 1 can receive a stronger load and can improve the strength as compared with the case where the load on the first region R is received only by the tent sheet 2 in the first region R. In another embodiment, when the position where the linear member 52 is connected in the partition pole 3p is a position in the middle (example: center) of each side of the regular pentagon, the tension area is two linear members adjacent to each other. It is a quadrangle formed by two compartment poles 3p (parts) adjacent to each other with 52.

_{However, as the load K 10} applied to the support member 51, for example, the load directly applied to the support member 51 or the load applied to the tent sheet 2 in the first region R is transmitted to the tent sheet 2 by deforming the tent sheet 2. Then, the load transmitted to the support member 51 by pushing the support member 51 due to the deformation of the tent sheet 2 and the load of the adjacent first region R are transmitted to the support member 51 via the linear member 52. Load, etc. Further, in the tension structure 5 of the top portion P, each linear member 52 is connected to the outer sleeve 4 via a holding member (not shown) extending inward of the tent sheet 2. The tension structure 5 of the top P not only improves the strength, but also pushes the top P upward to prevent water or the like from accumulating on the top P of the top.

In the tent 1, as shown in FIG. 13, each of the plurality of linear members 52 includes a first linear member 52 ₁₁ and a second linear member 52 ₁₂ . One end of the first linear member 52 ₁₁ is connected to a predetermined portion of the partition pole 3p, and the other end is connected to one end of the support member 51 in contact with the tent sheet 2. One end of the second linear member 52 ₁₂ is connected to a predetermined portion of the partition pole 3p (the _{same location as the first linear member 52 11} ), and the other end of the support member 51 does not contact the tent sheet 2. It is connected to a portion (the other end opposite to one end). That is, another triangular tension region A ₂₁ is formed by the support member 51, the two first linear members 52 ₁₁ and the second linear member 52 _12. Therefore, even if a load is applied to any of the vertices of the triangle, the load can be distributed to the left and right sides of the vertex. That is, when viewed from a plane substantially perpendicular to the surface of the first region R, the load on the first region R is distributed to both _{the plurality of first linear members 52 11} and the plurality of second linear members 52 _12. It can be transmitted to a plurality of compartment poles 3p in a dispersed manner. Therefore, the tent 1 distributes the load on the first region R to a plurality of two types of paths (first linear member 52 ₁₁ -partition pole 3p, second linear member 52 ₁₂ -partition pole 3p). I can take it. Therefore, the strength of the tent 1 as a whole can be further improved.
Further, in another adjacent linear member 52, for example, another triangular tension region A ₂₂ is formed by the _{support member 51, the two first linear members 52 21,} and the second linear member 52 _22. ing. As a result, for example, the load K ₂₀ applied downward to the support member 51 can be dispersed into the first linear member 52 ₁₁ and the first linear member 52 ₂₁ to obtain the load K ₂₁ and the load K _22. .. Similarly, for example, the load K ₂₀ applied upward to the support member 51 can be distributed to the first linear member 52 ₁₁ and the first linear member 52 _21. Then, the dispersed load can be further dispersed and transmitted to the plurality of compartment poles 3p. Therefore, the tent 1 distributes the load on the first region R to a plurality of two types of paths (first linear member 52 ₁₁ -partition pole 3p, first linear member 52 ₂₁ -partition pole 3p). I can take it. As a result, the tent 1 can more reliably disperse and transmit the load. The same applies when a load is applied upward to the support member 51. As a result, the strength of the tent 1 as a whole can be further improved. In another embodiment, each of the plurality of linear members 52 is a second linear member 52 ₁₂ (, 52 ₂₂ ) and a first linear member 52 ₁₁ (from the viewpoint of structure and ease of assembly). , 52 ₂₁ ) is not included.

The material of the linear member 52 is not particularly limited as long as it has a predetermined strength, and examples thereof include metals, inorganic materials, synthetic resins (fibers), and natural fibers. The shape of the support member 51 is not particularly limited as long as it has a predetermined height (thickness), and examples thereof include a rod-shaped member, a spherical member, and an ellipsoidal member. When the support member 51 is a sphere or an ellipsoid, the linear member 52 can be supported more stably. The material of the support member 51 is not particularly limited as long as it has a predetermined strength, and examples thereof include metals, inorganic materials, synthetic resins, and natural resins.

In the present embodiment, as a preferred embodiment, in the tent 1, as shown in FIG. 11, a position where two partition poles 3p intersect with each other (via the ring member 53) of one linear member 52. Is. Therefore, the load transmitted from the linear member 52 can be distributed and transmitted to the two compartment poles 3p, that is, the load distributed to each of the compartment poles 3p can be reduced to, for example, about half. Further, in the present embodiment, as a preferred embodiment, in the tent 1, as shown in FIG. 12, the first region R is a triangular shape composed of two linear members 52 adjacent to each other and a partition pole 3p. It is divided by a plurality of tension regions A _{11 to} A ₁₅ . By dividing the first region R into a plurality of triangular tension regions A _{11 to} A _{15 in this way, the load 10} on the first region R is efficiently applied to at least two linear members 52 in the first region R. And can be efficiently dispersed in the compartment pole 3p.

In the present embodiment, as a preferred embodiment, in the tent 1, the support member 51 is arranged at the center of gravity of a regular polygon which is the shape of the first region R. For example, as shown in FIG. 12, the first region R corresponds to a regular pentagonal region (of the equiside decahedron) of the seat member 21, and the support member 51 is arranged at the center of gravity of the regular pentagon. As a result, the load K ₁₀ to the first region R can be distributed from the support member 51 to each linear member 52 in a well-balanced manner, and the further distributed loads K _{11 to} K ₁₅ can be distributed to the regular pentagon (regular polygon). At each apex, each linear member 52 can be dispersed in each section pole 3p in a well-balanced manner. Therefore, the tent 1 can stably receive a stronger load without becoming unstable such as the support member 51 tilting. That is, the strength of the tent 1 can be improved more stably with respect to the load on the first region R.

Further, in the present embodiment, as a preferred embodiment, as shown in FIG. 3, a plurality of the first regions R including the first regions R adjacent to each other are partitioned on the tent sheet 2. However, when they are adjacent to each other, they may be adjacent to each other via vertices as shown in FIG. 3, or may be adjacent to each other via a shared side depending on the shape of the polyhedron of the tent sheet 2. The tent sheet 2 has a curved surface (example: a side surface of a cylinder or pillar that goes around the cylinder or pillar) forming a closed shape (a curved surface that is continuous in a substantially annular shape) when viewed from above, and at least a strip-shaped surface of a sphere (ball cap, Sphere band)), and in this case, it has the surface of the dome portion 11. At that time, the plurality of first regions R are continuous along a closed curved surface (the surface of the dome portion 11) so that the vertices or sides are in contact with each other (however, in the case of FIG. 3, the vertices are in contact with each other). Is arranged as a target. That is, five first regions R of the regular pentagon are continuously arranged along the surface of the dome portion 11 so that the vertices are in contact with each other. That is, while the partition poles 3p are shared so that the adjacent first regions R are in contact with each other at the vertices or sides, the plurality of first regions R are arranged and circled on the side surface of the dome portion 11 of the tent sheet 2. Therefore, the tent 1 applies a load to any of the first regions R not only to the tent sheet 2 of the first region R and the plurality of compartment poles 3p and the tension structure 5 in the first region R, but also to the first region R. It can be dispersed and received by the tent sheet 2 of the other first region R adjacent to both sides of the one region R, the plurality of linear members 52 in the other first region R, and the plurality of compartment poles 3p. Further, the load received by the other first region R adjacent to both sides of the first region R is received by the tent sheet 2 of the further adjacent first region R and a plurality of lines in the further other first region R. The shape member 52 and the plurality of compartment poles 3p can be dispersed and received. In this way, the load on any of the first regions R is received by the entire plurality of first regions R arranged along the tent sheet 2 on the curved surface (the surface of the dome portion 11) forming the closed shape. As a result, the tent 1 can receive an even stronger load as compared with the case where the load on the first region R is received only by the configuration in one first region R. That is, the tent 1 can further improve the strength against the load on the first region R, and by extension, the strength of the tent 1 as a whole can be further improved.

As a preferred embodiment in the present embodiment, in the tent 1, the tent sheet 2 has the shape of an icoside decahedron (a shape in which the lower portion is partially removed). In another embodiment, the tent sheet 2 may have the shape of a polyhedron, particularly a spherical polyhedron in which the vertices of the polygons constituting the polyhedron are inscribed in the sphere (having a circumscribed sphere), and the shape of the semiregular polyhedron. It may have the shape of an Archimedean solid or a quasi-regular polyhedron. Also in these cases, since the tent sheet 2 is close to a sphere, the surface area of the tent sheet 2 can be reduced with respect to the volume inside the tent sheet 2. As a result, the influence of the wind can be reduced and the strength against the wind can be relatively increased. Further, the lengths of the sleeve and the pole along the surface of the tent sheet 2 can be made relatively small with respect to the volume inside the tent sheet 2, and the tent can be made lighter.
