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, a plurality of sleeves formed along the surface of the tent sheet corresponding to the plurality of poles, and inserted through the plurality of poles; When the plurality of poles are inserted through the plurality of sleeves and the tent is installed on an installation surface, each of the plurality of poles is at a plurality of locations on the tent sheet. The plurality of sleeves cross each other, and each of the plurality of sleeves has the pole more than each of the other plurality of poles at or around the plurality of locations. A tent comprising a plurality of guide means for guiding the poles so that a case where they intersect on a side closer to the tent sheet and a case where they intersect on a far side are alternately arranged.

  In the tent of this aspect 1, at a plurality of locations where a certain pole intersects with another plurality of poles or in the vicinity thereof, the pole intersects on the side closer to the tent seat than each of the other plurality of poles, and far away Each of the plurality of sleeves is provided with guide means for guiding the poles so that the cases where they intersect at the sides are alternately arranged. In such a tent, when the user assembles the tent, the pole and the other plurality of poles can be easily arranged in a desired positional relationship by the guide means simply by inserting the pole through the sleeve. Then, at that time, the poles can be installed so that the case where the poles intersect each other on the side closer to the tent sheet than the other plurality of poles and the case where the poles intersect on the far side are alternately arranged. That is, a plurality of poles can be alternately combined with each other in the upper side / lower side / upper side / lower side /. Thereby, the 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, it is possible to satisfy both maintenance of strength and safety, and ease of assembly.

[Aspect 2]
The guide means is formed of two intersecting sleeves that intersect with each other and correspond to the two poles that intersect with each other, and one of the two intersecting poles is for the two intersecting with each other. The tent according to aspect 1, wherein the other two of the two poles that are inserted into one of the sleeves and intersect each other are inserted into the other of the two intersecting sleeves that intersect each other.

  In the tent according to the second aspect, the guide means is formed by mutually intersecting sleeves corresponding to two intersecting poles. Therefore, each of the two poles crossing each other can be installed on a desired side of the side close to and far from the tent sheet, and can be reliably crossed with each other. Therefore, both maintenance of strength and ensuring safety and ease of assembly can be satisfied.

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

  In the tent according to the third aspect, the guide means is formed by a crossing sleeve corresponding to one of the two poles crossing each other. Thereby, one of the two poles crossing each other is installed on one side of the side close to and far from the tent seat via the crossing sleeve, and the two poles crossing each other correspondingly are installed. By installing the other of the poles on the outer side 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. Thereby, both maintenance of strength and securing of safety and ease of assembly can be satisfied.

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

  In the tent of the fourth aspect, the plurality of sleeves are continuously formed while including the intersecting sleeves. Therefore, when the pole is inserted into the sleeve, the pole can be reliably and properly installed on the tent seat without jumping out of the sleeve in the middle. Thereby, both maintenance of strength and securing of safety and ease of assembly can be satisfied.

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

  In the tent of the fifth aspect, since the skirt is added below the dome-shaped (hemispherical) dome, the height in the tent can be increased by the amount of the skirt. Thereby, the comfortability of the height direction in a tent can be improved. In addition, the projected area of the figure formed at the lower end of the skirt is made smaller than the projected area of the figure formed at the lower end of the dome. Therefore, there is no need to increase the installation area of the tent, and the restriction on the installation location can be suppressed. As described above, a tent having a dome portion and a skirt portion on the tent sheet has a great advantage. However, the tent portion may weaken a crosswind or the like. Therefore, in this tent, the poles can be installed using the guide means so that the case where the poles cross on the side closer to the tent sheet than the other plurality of poles and the case where they cross on the far side are alternately arranged. Therefore, a plurality of poles can be installed in a high strength state, that is, in an arrangement as designed. Thereby, the habitability in the height direction can be improved, and an increase in the installation area can be suppressed, while maintaining a high strength state 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 among the plurality of sheet members, a boundary between a plurality of adjacent sheet members The line forms a chain boundary line that links 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 tents of the plurality of first sleeves are arranged along the vertexes of the polygon.

  In the tent of this aspect 6, a plurality of boundary lines between adjacent sheet members form a chain boundary line that links from the lower end on one side to the lower end on the other side of the dome, and along the chain boundary line The first sleeve is arranged. Therefore, the first sleeve is likely to be in a state along the chain boundary line, that is, along the side of the polygon. Furthermore, the first sleeve extends along a chain boundary line passing through a plurality of polygons. Here, since the adjacent polygons are in contact with each other at the apex, the first sleeve (and the tent sheet) on the chain boundary line before passing through the first pole is likely to be bent before and after such apex. . Therefore, the plurality of first sleeve guide means are arranged at the apexes of the polygon. By arranging the guide means at the apex of the polygon, the first sleeve is less likely to be bent before and after the apex, and the first pole extends along the sides of the polygons (chain boundary lines). The first sleeve can be inserted so as to extend. Therefore, when the tent 1 is assembled, the first pole can be easily inserted through the first sleeve, and the tent can be easily assembled.

[Aspect 7]
The tent according to aspect 6, wherein the tent sheet has a spherical polyhedron shape, and the plurality of sheet members constitute polygonal surfaces of the spherical polyhedron.

  In the tent of this aspect 7, the tent sheet (dome portion + skirt portion) has a spherical polyhedral shape. However, in this case, in the spherical polyhedron, the portion corresponding to the upper half of the sphere is a substantially hemispherical dome, and the portion corresponding to the lower half of the sphere is the lower side of the substantially hemisphere. Is a skirt having a shape cut by a plane parallel to the installation surface. In this case, since the tent sheet is more spherical, the curvature of the surface of the tent sheet when the tent is assembled is substantially the same at any position. Therefore, when assembling the tent, when the first pole is inserted into the first sleeve or when the tent is raised, the work of adjusting the condition of the sheet member of the tent sheet according to the position of the first sleeve 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 the aspect 8 tent, the tent sheet (dome portion + skirt portion) has an Archimedean solid shape. That is, since the tent sheet is even more spherical, when the tent is assembled, the work of adjusting the condition of the sheet 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, wherein the Archimedean solid includes icoside decahedron.

  In the tent of Embodiment 9, the tent sheet has an icoside decahedron shape. That is, it has a more spherical shape among Archimedean solids. Therefore, when the tent is assembled, the operation of adjusting the condition of the sheet 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 this aspect 10, a number of sleeves are arranged along the geodesic line of the tent sheet. Thereby, the length of the plurality of poles inserted through the plurality of sleeves can be made the shortest length, and the pole 3 can be inserted through the sleeve 4 more easily. Therefore, the time and labor required for installing the tent can be reduced, and the tent can be assembled more easily.

  Hereinafter, a tent 1 according to an 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, and the like without departing from the object and spirit of the present invention.

First, the overall configuration of the tent 1 will be described.
1-5 is a figure which shows the structural example of the tent 1 which concerns on embodiment. However, FIG. 1 is a perspective view of the tent 1 ((a) without a fly sheet 9 and (b) with a fly sheet 9), FIG. 2 is a front view of the tent 1, and FIG. 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 with the tent sheet 2, the plurality of poles 3 and the fly sheet 9 fixed 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 up-down direction, and relatively close to the bottom B of the tent 1. The direction is the lower side or the lower side, and the direction relatively approaching the top portion P of the tent 1 is the upper side or the upper side. A method along the surface of the tent 1 is a circumferential surface direction, and a direction parallel to the installation surface G is a planar direction. Further, viewing the tent 1 from the top P side downward is referred to as a plan view. In another embodiment, at least one of the tension structure 5 and the fly sheet 9 is not provided.

  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 shape in which a lower part of the lower hemispherical part is cut by a plane parallel to the installation surface G, with the upper hemispherical part as it is in a substantially spherical member. Yes. In other words, the tent sheet 2 has a shape approximating a spherical cap having a first solid angle with a solid angle larger than 2π steradian and smaller than 4π steradian, and the position where the solid angle is 0 is 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-like bottom B. In addition, the tent sheet 2 has a window 7, an entrance 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 an icoside decahedron (quasi-regular thirty dodecahedron or twelve icosahedron). Icoside decahedron (ICOSIDEDECAHEDRON) includes a dodecagon of regular pentagon and a dodecahedron of equilateral triangle, respectively. The substantially spherical shape of the tent sheet 2 is an imaginary plane parallel to the bottom surface of the lower hemispherical portion having a predetermined thickness in an icoside decahedron arranged with a regular pentagon as a top surface and a bottom surface. It has a shape cut by. However, the virtual plane is a plane connecting vertices of regular polygons, and is, for example, a plane passing through a position about 1/5 of the total height from the bottom. The upper hemispherical part contains six regular pentagons and ten regular triangles, and the lower part contains five partially cut regular pentagons and five regular triangles. Yes. The shape based on the shape of icoside decahedron is preferable in that it is close to the shape of a sphere, and thus, for example, the ratio of the surface area to the volume is reduced. The icoside decahedron can be said to be a geodesic polyhedron formed by a polygon having a geodesic line (geodesic line) as a side of a great circle of a sphere as a side. In addition, the substantially spherical shape of the tent sheet 2 is an Archimedean solid or a quasi-regular polyhedron in another embodiment, and is a spherical polyhedron in which the vertex of the polyhedron is inscribed in the sphere in another embodiment.

  The tent sheet 2 includes a dome portion 11 and a skirt portion 12. The dome portion 11 is a portion having a dome shape in the tent sheet 2, that is, an upper hemispherical portion of a substantially spherical member. The dome part 11 includes six regular pentagons and ten regular triangles. Hereinafter, a surface parallel to the installation surface G formed by the lower edge of the dome portion 11 is also referred to as an equator plane E. The equator plane E can be referred to as a boundary surface between the dome portion 11 and the skirt portion 12. The skirt portion 12 is a portion extending downward from the lower end edge of the dome portion 11 of the tent sheet 2, and is a lower hemispherical portion of the substantially spherical member, and the lower portion thereof is the installation surface. It is the shape cut | disconnected by the plane parallel to. The skirt portion 12 includes five pentagons and five regular triangles that are partially cut. However, the shapes of the dome portion 11 and the skirt portion 12 allow for a slight shift in dimensions (example: ± 5%) in consideration of manufacturing yield. In another embodiment, the tent sheet 2 does not include the dome portion 11 and the skirt 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 (described later) of the skirt 12 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 skirt portion 12 is located on the inner side of the outer edge of the dome portion 11 in plan view. Although the shape of the bottom B is originally a regular pentagon, it is a hexagon by shifting the midpoints of the four sides excluding one side of the entrance portion of the five sides of the regular pentagon. Thereby, the habitability in the plane direction is enhanced by expanding the bottom B.

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

  Each sleeve 4 is a sleeve-like or cylindrical 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 onto the surface of the tent sheet 2 substantially overlaps with the arrangement of the pole projected onto the surface of the tent sheet 2.

  The plurality of sleeves 4 include a plurality of first sleeves 4a and at least one second sleeve 4b. The first sleeve 4 a is arranged on the surface of the dome portion 11 so as to be along 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. Arranged (joined). The lower end portion on one side of the dome portion 11 is located, for example, on the equator plane E or in the vicinity of the equator plane E, and the lower end portion on the other side is opposite to the end portion on the one side with the central region of the dome portion 11 in between. It is located on the equator plane E on the side or in the vicinity of the equator plane E, and both have openings into which the poles 3 can be inserted. The first sleeve 4a intersects the equator plane E at an angle larger than 0 degree and smaller than 180 degrees. However, the central region of the dome portion 11 is the central portion of the equator plane E inside the dome portion 11. The second sleeve 4b is a sleeve 4 other than the first sleeve 4a. The second sleeve 4 b is disposed (joined) on the surface of the dome portion 11 so as to follow the surface of the dome portion 11 so as to surround the equator plane E except for the vicinity of the entrance D of the tent 1. The second sleeve 4b is disposed parallel to the equator plane E (without intersecting the equator plane E).

  Among the sleeves 4, the first sleeve 4 a is continuously formed so that the pole 3 does not protrude from the first sleeve 4 a during the insertion operation, and thus the inserted pole 3 is continuously covered. Is formed. Thereby, when the tent 1 is assembled, the pole 3 can be inserted all at once from the end on one side to the end on the other side of the first sleeve 4a of the tent sheet 2 that is two-dimensionally developed. On the other hand, among the sleeves 4, the second sleeve 4 b is formed intermittently so that the pole 3 is exposed in some places. Thereby, when the tent 1 is assembled, the tent sheet 2 is formed in a three-dimensional substantially spherical shape by the plurality of first poles 3a inserted through the plurality of first sleeves 4a. This is to make it easier for the user to assist with the hand when inserting the pole 3 into the second sleeve 4b. In another embodiment, the first sleeve 4a may be formed intermittently, and 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. The plurality of poles 3 inserted through the plurality of sleeves 4 are stretched on the installation surface G, so that 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 disassembled 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 through a first sleeve 4a formed in the dome portion 11. A portion of the first pole 3a on the dome portion 11 side is inserted through the first sleeve 4a so as to be along 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 skirt portion 12 side extends along the surface of the skirt portion 12 from the lower end portion on each of the one side and the other end side of the dome portion 11 to the installation surface G. G is reached and fixed to the installation surface G by the fixing member 8. A portion extending along the surface of the skirt 12 in the first pole 3a is coupled to the surface of the skirt 12 by a hook or the like. The first pole 3a intersects the equator plane E at an angle greater than 0 degree and less than 180 degrees on the surfaces of the dome part 11 and the skirt part 12. The second pole 3b is inserted through a second sleeve 4b formed along the equator plane E of the dome part 11. The second pole 3 b is inserted through the second sleeve 4 b and surrounds the equator plane E except for the vicinity of the entrance D of the tent 1 and is positioned along the surface of the dome portion 11. The second pole 3 b does not intersect the equator plane E on the surface of the dome portion 11 and is parallel.

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

  The material of the tent sheet 2 or the fly sheet 9 is not particularly limited as long as it can be used as a tent sheet or a fly sheet, and examples thereof include various types of synthetic resins such as nylon, tetron, and polyester. The material of the pole 3 is not particularly limited as long as it can be used as a pole material. For example, composite materials such as carbon fiber and fiber reinforced plastic, duralumin (aluminum alloy), metals such as steel and stainless steel, etc. Is mentioned. The material of the sleeve 4 is not particularly limited as long as it can be used as a sleeve. For example, a material similar to the material of the tent sheet can be used. Each material may be appropriately surface-treated.

  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 a quasi-regular thirty hour face, the plurality of sheet members 21 have polygonal shapes (regular pentagons and regular triangles). Adjacent sheet members 21 are joined to each other by joints (not shown) so as to share sides and vertices. Examples of the joining method include methods such as stitching, adhesion, and fusion. A joint portion between adjacent sheet members 21 forms a boundary line 22 between 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 a chain boundary line 23. However, chaining means that one end of a boundary line is connected to one end of the next boundary line, the other end of the next boundary line is further connected to one end of the next boundary line, and so on. A state in which lines are arranged in series and end portions are joined together. The plurality of sleeves 4 are arranged along a plurality of chain boundary lines 23. In another embodiment, at least a part of the shape of the sheet member 21 is a shape other than a polygon. In yet another embodiment, the tent sheet 2 is not composed of a plurality of sheet members 21, but a single sheet. It consists of members.

  Specifically, the plurality of sheet members 21 include a sheet member 21a having a regular pentagonal shape and a sheet member 21b having a regular triangular shape. The dome portion 11 has six regular pentagonal sheet members 21a and ten regular triangle sheet members 21b. In addition, the skirt 12 has five regular pentagonal sheet members 21a 'that are partially cut, and five regular triangular sheet members 21b. Among these, a plurality of first boundary lines 22a that are boundary lines 22 that intersect with the equator plane E or extend away from the equator plane E are chained to form a first chain boundary line 23a. On the other hand, a plurality of second boundary lines 22b, which are boundary lines 22 extending along the equator 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 a quasi-regular thirty-hedron, the chain boundary line 23, that is, the first chain boundary line 23a and the second chain boundary line 23b This corresponds to the geodesic line (the shortest distance line on the curved surface).

  However, the shape of the plurality of sheet members 21 refers to a joined portion in the sheet member 21, that is, a shape formed (or bordered) at a boundary line. Therefore, for example, that the shape of the sheet member 21 is a polygon means that the shape of the sheet member 21 formed (or bordered) at the boundary line (joining portion) is a polygon. Moreover, when the some sheet | seat member 21 has a polygonal shape, it does not necessarily need to be a strict polygon, and should just be a polygon substantially. The substantially polygonal shape includes, for example, a polygon that bulges so that each side of the polygonal shape of each sheet member 21 gently protrudes outward so that the tent sheet 2 approaches the shape of a sphere, Therefore, it includes a polygon whose sum of internal angles is 180 degrees or more. In the case of the present embodiment, the tent sheet 2 has a shape based on icoside decahedron (quasi-regular thirty hour face), but has a shape closer to a sphere. In addition, the sheet member 21 may include some 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 in FIG. 6, that is, a configuration in which the tension structure 5 is omitted in FIG. Each of the plurality of sleeves 4 is disposed along a plurality of boundary lines 22, that is, chain boundary lines 23. Each chain boundary line 23 is a great circle portion of 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 linkage boundary lines 23a. The plurality of first chain boundary lines 23a are formed along geodesic lines having the same length, and therefore have the same length. On the other hand, the second pole 3b inserted through the second sleeve 4b is disposed along the second chain boundary line 23b. The second chain boundary line 23b is formed along the geodesic line of the equatorial plane E. Since the geodesic line is longer than the geodesic line along the first chain boundary line 23a, the second chain boundary line 23b is It becomes longer than one chain boundary line 23a.

Next, the guide means will be described. The tent 1 includes a plurality of guide 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 locations on the tent sheet 2. Here, the strength of the tent 1 with respect to wind or the like changes depending on whether one pole crosses the upper side or the lower side of each of the plurality of other poles 3 at the plurality of places or the periphery thereof. . Therefore, in the present embodiment, as a preferable aspect, 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 the other pole 3 at the plurality of locations or the periphery thereof. Means 41 are provided. Specifically, when the predetermined pole 3 should pass the upper side of the other pole 3, the guide means 41 is configured so that the predetermined pole 3 passes the upper side and the other pole 3 passes the lower side. To guide. On the other hand, the guide means 41 guides both poles 3 so that when the predetermined pole 3 should pass the lower side of the other pole 3, the predetermined pole 3 passes the lower side and the other pole 3 passes the upper side. To do. As described above, the tent 1 is provided with a plurality of guide means 41 in each of the plurality of sleeves 4, so that the plurality of poles 3 can be crossed as designed, and the strength as designed can be exhibited. Can be secured. In particular, in the present embodiment, the plurality of guide means 41 are arranged so that the pole 3 passes through the side closer to the tent seat 2 than the other pole 3 (the lower side of the other pole 3) in any pole 3. The plurality of poles 3 are guided so that the case of intersecting and the case of intersecting so as to pass through the far side (the upper side of another pole 3) are alternately arranged.

As shown in FIG. 8, the guide means 41 _U1 of the guide means 41 includes two intersecting sleeves 4q-1, which intersect with each other, corresponding to three poles 3-1, 3-2. 4q-2. The guide means 41 _D1 of the guide means 41 is formed by two intersecting sleeves 4q-1 and 4q-3 that intersect with each other and correspond to the two poles 3-1 and 3-3 that intersect with each other. .

In the guide means 41 _U1 , one of the two poles 3 that intersect each other is one of the two intersecting sleeves 4q that intersect each other, and the intersecting sleeve 4q-1 that passes through the upper side. The other pole 3-2 of the two poles 3 that are passed through and intersect each other is the other of the two intersecting sleeves 4q that intersect each other, and is the other of the intersecting sleeves 4q-2 that passes through the lower side. It is inserted. On the other hand, in the guiding means 41 _D1 , the pole 3-1 that is one of the two poles 3 that intersect with each other is one that is one of the two intersecting sleeves 4q that intersect with each other. 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, and the intersecting sleeve 4q passing through the upper side. -2 is inserted. Therefore, the guide means 41 _U1 and the guide means 41 _D1 are divided into the case where the pole 3-1 crosses so that it passes the side farther from the tent seat 2 than the other pole 3-2, and the case where the pole 3-1 is the other pole 3 The poles 3-1 are guided so that the case where they intersect so as to pass through the side closer to the tent sheet 2 than -3 are alternately arranged.

In such a tent 1, each of the two poles 3-1, 3-2 and 3-1, 3-3 intersecting each other is guided closer to and far from the tent sheet 2 by the guide means 41 _{U 1} and 41 _{D 1.} It can be installed on the desired side of the sides and reliably cross each other. Thereby, the plurality of poles 3 can be arranged like a plain weave, and both the maintenance of the strength and safety of the tent 1 and the ease of assembly can be satisfied.

FIG. 9 is a perspective view showing another configuration example of the guide means 41 according to the embodiment. However, in this figure, the description of the tension structure 5 is omitted. Guiding means _{41 U2} of the guide means 41 is formed at the intersection sleeve 4q-2 corresponding to the one in which the pole 3-2 of the two poles 31 and 32 cross each other . Guiding means _{41 D2} of the guide means 41 is formed at the intersection sleeve 4q-1 corresponding to the one in which the pole 3-1 of the two poles 3-1 and 3-3 to cross each other .

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

In such a tent 1, the guiding means 41 _U2 and 41 _D2 are arranged so that each of the two poles 3-1, 3-2 and 3-1, 3-3 intersecting each other is closer to and far from the tent sheet 2. It can be installed on the desired side of the sides and reliably cross each other. Thereby, the plurality of poles 3 can be arranged like a plain weave, and both the maintenance of the strength and safety of the tent 1 and the ease of assembly can be satisfied.

Next, the method of assembling the tent 1 in the present embodiment is performed by the following method.
(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 skirt 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 skirt portion 12 is generally hidden on the lower side.
(2) The plurality of first poles 3a are inserted through the plurality of first sleeves 4a of the tent sheet 2. At this time, one first pole 3a is inserted into one first sleeve 4a, and both end portions of the first pole 3a protrude from both sides of the dome portion 11 with the first sleeve 4a interposed therebetween. FIG. 10 is a perspective view showing the state of the present (2) step in the state where the tent 1 is being assembled.
(3) While holding both ends of the plurality of first poles 3a, the plurality of first poles 3a are raised to make the dome portion 11 hemispherical. Then, both end portions of the plurality of first poles 3 a are attached to the plurality of hooks and the plurality of fixing members 8 attached to the skirt portion 12.
(4) Pass the second pole 3b to the second sleeve 4b. The whole is covered with a fly sheet 9 as necessary.
The tent 1 is assembled by the method as described above.

Thus, in the tent 1, each of the plurality of sleeves 4 includes the guide means 41 (41 _U1 , 41 _D1 / 41 _U2 , 41 _D2 ) for guiding the pole 3, so that the user can assemble the tent 1. By simply inserting the pole 3 into the sleeve 4, the guide 3 can easily arrange the pole 3 and the other plurality of poles 3 in a desired positional relationship. In particular, for each of the plurality of poles 3, the case where the poles 3 cross on the side closer to the tent seat 2 than the other plurality of poles 3 and the case where they cross on the far side are arranged alternately. Pole 3 can be installed. That is, a plurality of poles can be alternately combined with each other in the upper side / lower side / upper side / lower side /. Thereby, the 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 achieve both strength maintenance and safety and ease of assembly. In other words, if the plurality of poles 3 are combined on a two-dimensional plane and the crossing angle between the poles 3 in the plane is 90 degrees, the plurality of poles 3 combined is It can be said that they are combined like a plain weave. Thereby, the strength of the assembled structure can be increased without increasing the number of poles 3.

  In the present embodiment, as a preferred aspect, the plurality of intersecting sleeves 4q are included in the plurality of sleeves 4 formed continuously 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 jumping out from the sleeve 4 in the middle, and a plurality of poles 3 can be installed with high strength. Both maintenance of strength and safety, and ease of assembly can be satisfied.

  In the present embodiment, as a preferred mode, a plurality of boundary lines 22 between adjacent sheet members 21 form a chain boundary line 23 that links from the lower end on one side to the lower end on the other side of the dome portion 11. The first sleeve 4 a is disposed 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 a chain boundary line 23 passing through a plurality of polygons. Here, since the adjacent polygons are in contact with each other at the apex, the first sleeve 4a (and the tent sheet 2) on the chain boundary line 23 before being inserted through the first pole 3a is bent before and after such apex. Prone to state. Therefore, the guide means 41 of the plurality of first sleeves 4a are arranged at the vertexes of the polygon. By arranging the guide means 41 at the apex of the polygon, the first sleeve 4a is hardly bent even before and after the apex, and the first pole 3a is connected to a plurality of polygonal sides (chain boundary line 23). Can be inserted through the first sleeve 4a. Therefore, when the tent 1 is assembled, 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 mode, in the tent 1, the skirt 12 is added below the dome-shaped (hemispherical) dome 11, so that the height in the tent 1 can be increased by the skirt 12. . Thereby, as shown in FIG. 5, the living space in the height direction (direction between the bottom portion B and the top portion P) in the tent 1 can be increased, such that the user M1 can stand up in the tent 1. In addition, the projected area S _B of the bottom B on the installation surface G is smaller than the projected area S _E of the equatorial plane E on the installation surface G. 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) , Can limit the installation location. That is, an increase in the installation area can be suppressed while increasing the living space in the height direction. For example, when the diameter is 3 m, the ceiling height is about 1.5 m in the conventional dome-shaped tent, but the ceiling height is about 2.1 m in the present tent 1. That is, the ceiling height can be increased by about 40% without increasing the installation area. Further, in the tent 1, the plurality of first sleeves 4 a are disposed from the lower end portion on one side to the lower end portion on the other side in the dome portion 11, but are not disposed on the skirt portion 12. Therefore, the plurality of first poles 3a among the plurality of poles 3 can be easily inserted into the plurality of first sleeves 4a. The tent sheet 2 in FIG. 10 shows a state in which a plurality of first poles 3 a are inserted into a plurality of first sleeves 4 a on the dome portion 11. Thereby, after that, the both ends of each of the plurality of first poles 3a are raised, and the tent 1 can be easily assembled as shown in FIG. 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 present tent 1 having a comfortable space in which a user can stand and work inside a living room, such as a living room, instead of a conventional tent that only sleeps in a sleeping bag. For example, even a general family who enjoys auto camp can easily assemble the original tent 1. Thereby, a tent excellent in comfort, compactness, and ease of assembly can be obtained.

In the present embodiment, as a preferred mode, as shown in FIG. 5, the range of the contact angle α formed by the side surface W of the skirt 12 and the installation surface G is greater than 90 degrees and smaller than 180 degrees.
In such a tent 1, the lower portion of the tent sheet 2, that is, the bottom portion 12 has a shape that is narrowed toward the lower side. That is, inside the tent 1, the side surface W extends outward from the bottom surface (bottom portion B) of the tent 1 toward the boundary (equatorial plane E) with the dome portion 11 at the hem portion 12, and the hem portion at the dome portion 11. It becomes a shape which squeezes inward as it goes to the ceiling (top part P) from the boundary (equatorial plane E) between the part 12 and the dome part 11. Therefore, even when the user M2 is seated near the side surface W of the tent 1 inside the tent 1, the user M2 presses the head as compared with a tent having only a dome (conventional dome-shaped tent). Can be suppressed. Thereby, the living space of the planar direction in the state which the user M2 sat down can be increased. That is, it is possible to increase the living space in the plane direction and enhance the comfortability.

  Thus, although the tent 1 having the dome portion 11 and the skirt portion 12 on the tent sheet 2 has a great advantage, the tent portion 12 may weaken the wind due to a crosswind or the like. Therefore, as a preferable aspect in the present embodiment, in the tent 1, the pole 3 intersects on the side closer to the tent seat 2 (lower side) than each of the other plurality of poles 3 and on the far side (upper side). Since the poles 3 can be installed by using the guide means 41 so as to be alternately arranged, the plurality of poles 3 can be installed in a high strength state, for example, as designed. Thereby, the state of high strength of the tent 1 can be maintained while providing the advantages of improving the comfortability in the height direction and suppressing the increase in the installation area.

  Moreover, as a preferable aspect in this Embodiment, in the tent 1, the tent sheet | seat 2 has the shape of icoside decahedron (however, the shape from which the lower part was partly removed, hereafter the same). In another embodiment, in the tent 1, the tent sheet 2 may have a polyhedron shape, in particular, a spherical polyhedron shape in which a vertex of a polygon constituting the polyhedron is inscribed in a sphere (having a circumscribed sphere), It may have the shape of a semi-regular polyhedron, or may have the shape of an Archimedean solid or a quasi-regular polyhedron. Also in these cases, in this case, since the tent sheet 2 is more spherical, 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 the tent 1 is assembled, the condition of the sheet member 21 of the tent sheet 2 is adjusted by the position of the first sleeve 4a when the first pole 3a is inserted through the first sleeve 4a or when the tent 1 is raised. Therefore, the tent 1 can be assembled more easily. In addition, the tent sheet 2 does not need to have the shape of these spherical polyhedrons or Archimedean solids (semi-regular polyhedron, quasi-regular polyhedron, quasi-regular thirty-two-sided (including icoside decahedron)) in a strict sense What is necessary is just to have the shape of a substantially spherical polyhedron or a substantially Archimedean solid, that is, a substantially spherical polyhedron or a Archimedean solid. “Substantially having these shapes” means to include shapes having deformation such that each side is rounded and curved, or each surface is rounded and curved.

  Moreover, as a preferable aspect in the present embodiment, the plurality of sleeves 4 are arranged along the geodesic line of the tent sheet 2. Accordingly, the length of the plurality of poles 3 inserted through the plurality of sleeves 4 can be made the shortest, and the pole 3 can be inserted through the sleeve 4 more easily. Therefore, the time and labor required for installing 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 preferable aspect, the tent 1 further includes a tension structure 5. FIGS. 11-13 is a figure which shows the structural example of the tension structure 5 which concerns on embodiment. However, FIG. 11 is a perspective view illustrating a configuration example of the tension structure 5 of the tent 1, FIG. 12 is a schematic diagram illustrating another configuration example of the tension structure 5, and FIG. 13 illustrates an operation of the tension structure 5. It is a schematic diagram.

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

  The tent 1 includes a tension structure 5 in the first region R. The tension structure 5 improves the load resistance of the tent 1 by dispersing 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 distributes the load generated in the first region R to the plurality of tension regions A and further distributes 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. It can also be said that the load resistance of the tent 1 is improved. In the first region R of the top portion P, the tension structure 5 is provided inside the tent sheet 2. The tension structure 5 at the top portion P pushes up the top portion P from the inside toward 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 extend through the tent sheet 2 at the top P to the outside. The tension structure 5 at 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 string having one end coupled to at least one partition pole 3p and the other end coupled to the support member 51. The position at which the linear member 52 is coupled to the partition pole 3p is the position where the two partition poles 3p intersect, corresponding to the position of the apex of the regular pentagon of the sheet member 21. In another embodiment, the position where the linear member 52 is coupled to the partition pole 3p is a position in the middle (eg, center) of each side of the regular pentagon. The support member 51 is located in the first region R, for example, is located 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 having. 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 without being joined to the surface of the tent sheet 2, and is supported (held) at a balanced position by the plurality of linear members 52. In another embodiment, the support member 51 is disposed at the center of gravity of the regular polygon in the first region R. In yet another embodiment, the support member 51 is joined to the surface of the tent sheet 2. However, the term “coupled” includes not only a case where the members are joined (joined) in a state where the members are in direct contact but also a 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 coupled 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 passes through the ring.

  The first region R surrounded by the plurality of partition poles 3 p 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 regarded as a triangular region surrounded by two linear members 52 adjacent to each other whose other end is 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 that is the apex of the triangle, the force can be distributed to the two linear members 52 that are the left and right sides. The distributed force is received by the partition 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 regular pentagonal first region R is divided into five triangular tension regions A _{11 to} A ₁₅ . That is, each of the five tension regions A _{11 to} A ₁₅ has a triangular shape surrounded by two linear members 52 adjacent to each other, the other end of which is joined to the support member 51, and one partition pole 3p. It is an 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 It was dispersed in linear member 52 of the present, each of which can be the load _K 11 _{~K 15.} Load _K 11 _{~K 15} dispersed are respectively received by a plurality of partition pole 3p. That is, the tensile (example: the linear member 52) and compression: integrated (exemplified compartment pole 3p) and a good balance, it is possible to load K ₁₀ is balanced well dispersed. As a result, the tent 1 can receive a stronger load and improve the strength compared to 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 in the partition pole 3p is coupled is in the middle (eg, center) of each side of the regular pentagon, the tension region is two linear members adjacent to each other. 52 is a quadrangle formed by two partition poles 3p (parts) adjacent to each other.

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

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 . The first linear member 52 ₁₁ is coupled to one end of a predetermined portion of the partition pole 3p, is coupled to one end portion contacting the other end to the tent sheet 2 in the support member 51. The second linear member 52 ₁₂ is coupled to one end of a predetermined portion of the partition pole 3p (same location as the first linear member 52 _11), not in contact with the other end to the tent sheet 2 in the support member 51 and the other end It is couple | bonded with the part (the other end part on the opposite side to one end part). That is, by the support member 51 two first and linear members _{52 11} and the second linear member _{52 12,} the tension area _{A 21} of another triangle is formed. Therefore, even if a load is applied to any vertex of the triangle, the load can be distributed to the left and right sides of the vertex. That is, when viewed in a substantially perpendicular plane to the surface of the first region R, the load on the first region R, dispersed in both the plurality of first linear members 52 ₁₁ and a plurality of second linear members 52 ₁₂ Can be transmitted in a distributed manner to a plurality of partition 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 -compartment pole 3p, second linear member 52 ₁₂ -compartment pole 3p). I can take it. Therefore, the strength of the tent 1 as a whole can be further improved.
Further, in another linear member 52 adjacent well, for example, by a support member 51 two first linear member 52 _21, and the second linear member 52 _22, the tension area A ₂₂ of another triangle is formed ing. Thereby, for example, the load K ₂₀ applied downward to the support member 51 can be distributed to the first linear member 52 ₁₁ and the first linear member 52 ₂₁ to be 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 . And the distributed load can be further distributed and transmitted to a plurality of partition 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 -compartment pole 3p, first linear member 52 ₂₁ -compartment pole 3p). I can take it. As a result, the tent 1 can more reliably distribute 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 includes 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 shape, and an elliptical shape. 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 mode, in the tent 1, as shown in FIG. 11, the position where one linear member 52 is joined (via the ring member 53) intersects two partition poles 3p. It is. Therefore, the load transmitted from the linear member 52 can be distributed and transmitted to the two partition poles 3p, that is, the load distributed per one of the partition poles 3p can be reduced to, for example, about half. Moreover, in this Embodiment, as a preferable aspect, in the tent 1, as shown in FIG. 12, the 1st area | region R is the triangle comprised by the two linear members 52 and division pole 3p which mutually adjoin each other. It is divided by a plurality of tension areas A _{11 to} A ₁₅ . Thus, by dividing the first region R by the plurality of triangular tension regions A _{11 to} A ₁₅ , the load ₁₀ to the first region R is efficiently applied to at least the two linear members 52 in the first region R. And can be efficiently distributed to the partition poles 3p.

In the present embodiment, as a preferred aspect, in the tent 1, the support member 51 is arranged at the center of gravity of a regular polygon that 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 icoside decahedron) of the sheet member 21, and the support member 51 is disposed at the center of gravity of the regular pentagon. Thereby, the load _{K 10} to the first region R, the support member 51 can be distributed in good balance to the linear member 52, further load _K 11 _{~K 15} dispersed pentagonal of (regular polygon) It is possible to disperse in a balanced manner from each linear member 52 to each partition pole 3p at each vertex. Therefore, the tent 1 can stably receive a stronger load without becoming unstable such as the support member 51 being inclined. That is, the tent 1 can improve the strength more stably against the load applied to the first region R.

  Furthermore, in the present embodiment, as a preferred mode, as shown in FIG. 3, the tent sheet 2 has a plurality of the first regions R including the first regions R adjacent to each other. However, when it adjoins mutually, as shown in FIG. 3, it may adjoin through a vertex, and depending on the shape of the polyhedron of the tent sheet | seat 2, it may adjoin through a shared edge | side. The tent sheet 2 has a curved surface (example: side surface of the cylinder or column that surrounds the cylinder or column, or at least a belt-shaped surface (spherical cap, In this case, it has the surface of the dome part 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). Are arranged. That is, five regular pentagonal first regions R are successively arranged along the surface of the dome portion 11 so that the apexes are in contact with each other. That is, the plurality of first regions R are arranged side by side on the side surface of the dome portion 11 of the tent sheet 2 while sharing the partition pole 3p so that the adjacent first regions R are in contact with each other at the apexes or sides. Therefore, the tent 1 applies the load to any of the first regions R not only to the tent sheet 2 of the first region R and the plurality of partition poles 3p and the tension structure 5 in the first region R, but also to the first region R. The tent sheet 2 in the other first region R adjacent to both sides of the one region R and the plurality of linear members 52 and the plurality of partition poles 3p in the other first region R can be dispersed and received. Further, the loads received by the other first regions R adjacent to both sides of the first region R are further separated from the tent sheet 2 of the further adjacent first region R and a plurality of lines in the other first region R. The member 52 and the plurality of partition poles 3p can be distributed 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 having a curved surface (the surface of the dome portion 11) that forms a closed shape. As a result, the tent 1 can receive a much stronger load as compared with the case where the load on the first region R is received only by the configuration in the first region R. That is, the tent 1 can further improve the strength against the load applied to the first region R, and further improve the strength of the tent 1 as a whole.

  As a preferable aspect in the present embodiment, in the tent 1, the tent sheet 2 has an icoside decahedron shape (a shape in which the lower portion is partially removed). In another embodiment, the tent sheet 2 may have a shape of a polyhedron, in particular, a spherical polyhedron in which a vertex of a polygon constituting the polyhedron is inscribed in a sphere (having a circumscribed sphere). And may have the shape of an Archimedean solid or a quasi-regular polyhedron. Also in these cases, since the tent sheet 2 is nearly spherical, the surface area of the tent sheet 2 with respect to the volume in the tent sheet 2 can be reduced. Thereby, the influence of a wind can be made small and the intensity | strength with respect to a wind can be raised relatively. Further, the length of the sleeve and the pole along the surface of the tent sheet 2 with respect to the volume in the tent sheet 2 can be made relatively small, and the tent can be further reduced in weight.
