  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In this specification, terms indicating directions and positions (for example, terms including “up”, “down”, “front”, “back”, “left”, “right”, etc.) are used, but these terms limit the technical scope of the present invention. is not. In the drawing, “Fr” indicates “front”, “Rr” indicates “rear”, “L” indicates “left”, “R” indicates “right”, and “U” indicates “ “Up” indicates “D” indicates “Down”.

  With reference to FIG. 1 thru | or FIG. 3, the tent 1 which concerns on this embodiment is demonstrated. FIG. 1 is a perspective view showing the tent 1. FIG. 2 is a plan view showing a blank of the outer cylindrical portion 10 of the tent 1. FIG. 3 is a plan view showing a blank of the intermediate tube portion 20 of the tent 1.

  As shown in FIG. 1, the tent 1 has a substantially triangular prism shape and is installed on the installation surface GL. The tent 1 is a paper corrugated board that is assembled into a cylindrical shape extending in the left-right direction. The “left-right direction” is an example of the “longitudinal direction” in the claims, and the “front-rear direction” is an example of the “width direction” in the claims.

  The tent 1 includes a pair of outer cylindrical portions 10 and an intermediate cylindrical portion 20. Each of the pair of outer cylindrical portions 10 is formed in a substantially bottomed cylindrical shape having a substantially equilateral triangular cross section. The pair of outer cylinder portions 10 constitute both end portions of the tent 1 in the left-right direction. The intermediate cylinder portion 20 is formed in a cylindrical shape having a substantially equilateral triangular cross section. The intermediate cylinder part 20 connects the pair of outer cylinder parts 10 and constitutes an intermediate part in the left-right direction of the tent 1. In addition, since a pair of outer side cylinder part 10 is formed in the same shape (shape reversed right and left), below, the one outer side cylinder part 10 is demonstrated.

  The outer cylinder part 10 and the intermediate cylinder part 20 are each configured by connecting a plurality of blanks. Each blank is formed by punching a corrugated board with a paper punching device. The corrugated board is, for example, a well-known one in which a liner 1B is bonded to both front and back surfaces of a corrugated shin 1A (see FIGS. 2 and 3). The corrugated board is reinforced by, for example, bonding a liner 1B containing a large amount of virgin pulp to a high-strength medium shin 1A. 2 and 3 show the liner 1B on the front side (the outer surface side of the tent 1). In the present specification, a direction parallel to the central shin 1A of the corrugated board is referred to as a “step direction”, and a direction orthogonal to the step direction is referred to as a “flow direction”. In the drawing, “X” indicates “stage direction” and “Y” indicates “flow direction”.

<Configuration of the outer cylinder>
As shown in FIG. 2, the outer cylindrical portion 10 (the blank) includes an outer bottom surface plate 11, two outer side surface plates 12, and an outer end surface plate 13. Each of these face plates 11 to 13 is manufactured in a separated state. Since the two outer side plates 12 are the same, FIG. 2 shows one outer side plate 12.

  The outer bottom surface plate 11 is a member placed on the installation surface GL in a state where the tent 1 is assembled (see FIG. 4 and the like). The outer bottom surface plate 11 is formed in a rectangular shape that is long in the step direction. A bottom ruled line 11 </ b> A extending in the flow direction is formed at the center in the step direction of the outer bottom plate 11. The bottom ruled line 11A is a ruled line in which the liner 1B on the back side is crushed linearly in the thickness direction.

  The two outer side plates 12 are members that are connected to both ends in the front-rear direction of the outer bottom plate 11 in a state in which the tent 1 is assembled (see FIG. 1). Each outer side plate 12 is formed in the same size and shape as the outer bottom plate 11. Note that no ruled line is formed on each outer side surface plate 12.

  The outer end face plate 13 is a member that closes a part of the right end face (or left end face) of the outer cylindrical portion 10 in a state where the tent 1 is assembled (see FIG. 1). The outer end face plate 13 is formed in a rectangular shape that is long in the step direction. More specifically, the dimension in the step direction of the outer end face plate 13 is formed to be the same as the dimension in the step direction of the outer bottom face plate 11, and the dimension in the flow direction of the outer end face plate 13 is larger than the dimension in the flow direction of the outer bottom face plate 11. It is short.

  An end face ruled line 13 </ b> A extending in the flow direction is formed at the center in the step direction of the outer end face plate 13. The outer end face plate 13 is formed with a pair of inclined ruled lines 13B extending obliquely with respect to the flow direction. The pair of inclined ruled lines 13B is formed to be inclined toward the end face ruled lines 13A from both ends (a pair of corners opposed to the flow direction) of one side in the flow direction of the outer end face plate 13 toward the other side in the flow direction. The pair of inclined ruled lines 13B are formed to be line symmetric with respect to the end face ruled line 13A. The angle formed by each inclined ruled line 13B and one side in the flow direction of the outer end face plate 13 is 60 degrees. Note that the end ruled lines 13A and the inclined ruled lines 13B are the same ruled lines as the bottom ruled lines 11A.

<Configuration of intermediate cylinder>
As shown in FIG. 3, the intermediate cylinder portion 20 (a blank thereof) includes an intermediate bottom plate 21 and two intermediate side plates 22. These face plates 21 and 22 are each manufactured in a separated state.

  The intermediate bottom plate 21 is a member placed on the installation surface GL in a state where the tent 1 is assembled (see FIG. 6). The intermediate bottom plate 21 is formed in a rectangular shape that is long in the step direction. The intermediate bottom plate 21 is formed in a rectangular shape that is slightly larger than the outer bottom plate 11. At one end in the step direction of the intermediate bottom plate 21, an extended piece 23 is provided in a state of being connected via an intermediate ruled line 21A. The intermediate ruled line 21A is the same ruled line as the bottom ruled line 11A.

  The two intermediate side plates 22 are members that are connected to the rear end of the intermediate bottom plate 21 in a state where the tent 1 is assembled and form a triangular cross section similar to the outer cylindrical portion 10 (see FIG. 1). Each intermediate side plate 22 is formed in the same size and the same shape as the intermediate bottom plate 21 excluding the extending piece 23. A substantially elliptical operation hole 24 is formed in the intermediate side surface plate 22 arranged on the front side in the assembled state of the tent 1. The operation hole 24 is formed in the center in the flow direction on one side in the step direction of the intermediate side plate 22. Although the details will be described later, the intermediate side plate 22 with the operation hole 24 opened constitutes a door portion 25 for opening and closing the doorway D of the tent 1.

<Blank connection process of outer cylinder part>
With reference to FIG. 4 and FIG. 5, a blank connecting process of the outer cylindrical portion 10 will be described. FIG. 4 is a perspective view illustrating a blank connecting process of the outer cylindrical portion 10. FIG. 5 is a perspective view showing a state in which the outer cylindrical portion 10 is deformed into the storage shape S1. In the following description, workers include specialized workers, users of the tent 1 and the like.

  First, as shown in FIG. 4, the operator connects one side (lower end) in the step direction of the two outer side plates 12 to both sides in the step direction (front-rear direction) of the outer bottom plate 11 with an adhesive tape T. The two outer side plates 12 are connected to the outer bottom plate 11 via the first outer folding line 14. Subsequently, the worker connects the other sides (upper ends) of the two outer side plates 12 in the step direction with the adhesive tape T. The two outer side plates 12 are connected to each other via the second outer folding line 15. In this state, the outer bottom surface plate 11 and the two outer side surface plates 12 form a cylindrical shape having a substantially equilateral triangular cross section.

  Next, the operator connects one side in the flow direction of the outer end face plate 13 to one side in the flow direction of the outer bottom plate 11 with an adhesive tape T (see FIG. 1). The outer end face plate 13 is connected to the outer bottom face plate 11 via the third outer folding line 16. In this state, the bottom ruled line 11 </ b> A of the outer bottom face plate 11 and the end face ruled line 13 </ b> A of the outer end face plate 13 are arranged on the same straight line to form one fourth outer folding line 17. The outer bottom surface plate 11 and the outer end surface plate 13 are formed so as to be foldable by a fourth outer fold line 17 extending in the left-right direction at the center in the front-rear direction.

  The blank connection of the outer cylinder part 10 is completed by the above. The outer end face plate 13 may be connected to the outer bottom surface plate 11 before each outer side surface plate 12 is connected to the outer bottom surface plate 11.

  As shown in FIG. 5, the connected outer cylinder part 10 is formed so as to be deformable into a storage shape S1. Specifically, the worker bends the outer bottom surface plate 11 and the outer end surface plate 13 along the fourth outer fold line 17 so as to protrude upward. Accordingly, the two outer side surface plates 12 are bent at the second outer fold line 15 inward so as to overlap each other. Then, the outer cylinder portion 10 is folded in the first outer fold line 14, the second outer fold line 15, and the fourth outer fold line 17 so that the outer bottom face plate 11 is sandwiched between the two outer side face plates 12. Deformation to S1 The outer cylinder part 10 is stored in a storage place such as a warehouse in a state of being deformed into the storage shape S1.

<Intermediate tube blank connection step, etc.>
With reference to FIG. 6 and FIG. 7, a blank connecting step of the intermediate cylinder portion 20 and the like will be described. FIG. 6 is a perspective view for explaining a blank connecting step of the intermediate cylinder portion 20. FIG. 7 is a perspective view showing a state in which the intermediate cylinder portion 20 is deformed into the storage shape S2.

  First, as shown in FIG. 6, the operator connects one side in the step direction of the intermediate side plate 22 without the operation hole 24 to one side in the step direction of the intermediate bottom plate 21 with the adhesive tape T. The rear intermediate side plate 22 is connected to the intermediate bottom plate 21 via the intermediate folding line 26. Subsequently, the worker connects one side in the step direction of the intermediate side plate 22 in which the operation hole 24 is formed to the other side in the step direction of the rear side plate 22 (see FIG. 1). The front intermediate side plate 22 is connected to the rear intermediate side plate 22 via the hinge wire 27. In this state, the intermediate bottom plate 21 and the two intermediate side plates 22 are connected in a row in the step direction.

  Thus, the connection of the blank of the intermediate cylinder part 20 is completed. Note that the two intermediate side plates 22 may be connected to each other before the rear intermediate side plate 22 is connected to the intermediate bottom plate 21.

  As shown in FIG. 7, the connected intermediate cylinder part 20 is formed to be deformable into the storage shape S2. More specifically, the operator bends at the intermediate folding line 26 so that the rear intermediate side surface plate 22 overlaps the intermediate bottom surface plate 21. Further, the worker bends the hinge side 27 so that the front intermediate side plate 22 (door portion 25) is overlapped with the rear intermediate side plate 22. Then, the intermediate cylinder part 20 is deformed into a storage shape S <b> 2 folded by the intermediate folding line 26 and the hinge line 27 so that the two intermediate side face plates 22 are laminated on the intermediate bottom face plate 21. The intermediate cylinder part 20 is stored in a storage place such as a warehouse in a state of being deformed into the storage shape S2.

  In addition, the joined intermediate cylindrical portions 20 are assembled into a substantially equilateral triangular cylindrical shape with both left and right lateral ends open by bending the face plates 21 and 22 at about 60 degrees along the lines 26 and 27 (see FIG. 1). ). In this state, the front intermediate side plate 22 is connected to the rear intermediate side plate 22 via the hinge wire 27 to form the door portion 25.

<Tent assembly process>
Next, the assembly process of the tent 1 will be described with reference to FIG. 1, FIG. 8, and FIG. FIG. 8 is a perspective view for explaining an assembly process of the outer cylindrical portion 10. FIG. 9 is a perspective view showing a state in which the door portion 25 of the tent 1 is opened.

  First, the operator carries two outer cylinder portions 10 and one intermediate cylinder portion 20 as one set from the storage location to the installation location. Each outer cylinder part 10 and the intermediate cylinder part 20 are conveyed in the state deform | transformed into storage shape S1, S2 (refer FIG. 5 and FIG. 7).

  The operator opens the folded outer cylindrical portion 10 in the front-rear direction, and forms a cylindrical shape with the outer bottom surface plate 11 and the two outer side surface plates 12 (see FIG. 4). In this state, one end surface (the right end surface in FIG. 4) of the outer cylinder portion 10 is opened as a whole. Next, as shown in FIG. 8, the operator bends the front and rear sides of the outer end face plate 13 at each inclined ruled line 13 </ b> B to form a pair of front and rear engagement pieces 13 </ b> C. In this state, the outer end face plate 13 is formed in a substantially trapezoidal shape when viewed from the plane, and each engagement piece 13C is formed in a substantially triangular shape when viewed from the front. Subsequently, the operator bends the outer end face plate 13 along the third outer folding line 16 and inserts a pair of front and rear engaging pieces 13C into the inner side of the cylindrical shape formed by the three face plates 11 and 12 (see FIG. 9). The outer end face plate 13 closes most of the lower side of the other end face (left end face in FIG. 9) of the outer cylindrical portion 10. A substantially triangular ventilation opening V is formed in the upper part of the other end surface of the outer cylindrical portion 10. As described above, the two outer cylindrical portions 10 are assembled into a substantially bottomed cylindrical shape with one end face in the left-right direction opened.

  Next, an operator opens the intermediate | middle cylinder part 20 folded in the front-back direction on the installation surface GL (refer FIG. 6). Subsequently, as shown in FIG. 9, the operator turns the outer bottom plate 11 of each assembled outer cylinder portion 10 downward and faces the open surfaces of the pair of outer cylinder portions 10 in a posture facing each other. The outer cylinder part 10 is arrange | positioned on the installation surface GL. Specifically, the pair of outer cylindrical portions 10 are arranged in a state where they are overlapped on the left and right end portions of the intermediate bottom plate 21 of the intermediate cylindrical portion 20 with an interval in the left-right direction. In addition, it is preferable that the overlap width of each outer side cylinder part 10 and the intermediate | middle cylinder part 20 is about 30-100 mm.

  Next, the operator bends the rear intermediate side plate 22 along the intermediate folding line 26 (see FIG. 6), and bends the front intermediate side plate 22 along the hinge line 27 (see FIG. 1). Then, as shown in FIG. 1, the intermediate cylindrical portion 20 is assembled into a cylindrical shape having a substantially equilateral triangular cross section so as to connect the pair of outer cylindrical portions 10 (between the pair of outer cylindrical portions 10). It will be in the state arrange | positioned on the installation surface GL. Moreover, the both ends of the intermediate | middle cylinder part 20 will be in the state which overlapped with the outer surface of the outer side cylinder part 10 (refer FIG. 1). As shown in FIG. 1, the front intermediate side plate 22 as the door portion 25 is held in contact with the outer side plate 12 of each outer cylindrical portion 10 by its own weight, and a pair of outer cylindrical portions 10 (outer sides). The entrance D (see FIG. 9) formed between the side plates 12) is closed (covered).

  Thus, the assembly of the tent 1 is completed. Inside the tent 1, there is a space that is long in the left-right direction so that one adult can lie down. The extension piece 23 of the intermediate cylinder part 20 is provided in a state extending forward from the front end of the intermediate bottom plate 21. In addition, although illustration is abbreviate | omitted, you may affix an adhesive tape on the overlap part of each outer cylinder part 10 and the intermediate cylinder part 20 so that each outer cylinder part 10 and the intermediate cylinder part 20 may not isolate | separate.

  When the user enters the interior of the tent 1, the user places his / her hand (finger) on the operation hole 24 of the door portion 25 (front intermediate side plate 22), and moves the door portion 25 upward with the hinge wire 27 as the center. (See FIG. 9). Thereby, the entrance / exit D of the tent 1 is opened, and the user can enter the tent 1 through the entrance / exit D. Further, the user inside the tent 1 can turn upward by pushing the door portion 25 outward to open the entrance D, and can go out of the tent 1.

  When removing the tent 1 after use, the operator performs the reverse process of the assembly process of the tent 1 described above, and divides the tent 1 into two outer cylinder parts 10 and an intermediate cylinder part 20. Each outer cylinder part 10 and the intermediate cylinder part 20 are stored in a storage place in a state where the outer cylinder part 10 and the intermediate cylinder part 20 are folded into the storage shapes S1 and S2 again, or are bundled and discarded.

  The tent 1 according to the present embodiment described above is formed so as to be divided into two outer cylindrical portions 10 and one intermediate cylindrical portion 20. According to this configuration, by dividing the tent 1 into three parts, the length of the tent 1 in the left-right direction (longitudinal direction) can be reduced to about 1/3 compared to a tent that cannot be divided. Thereby, the divided | segmented outer cylinder part 10 and the intermediate | middle cylinder part 20 can be formed in the magnitude | size which is easy to carry for an operator. Further, the tent 1 can be stored in a storage place such as a warehouse in a state of being divided into three. Thereby, compared with the tent which cannot be divided | segmented, the storage space of the tent 1 (the outer cylinder part 10 and the intermediate cylinder part 20) can be made small.

  Moreover, in the tent 1 according to the present embodiment, the intermediate cylinder portion 20 includes the door portion 25 that rotates around the hinge line 27 extending in the left-right direction. And the doorway D which the door part 25 opens and closes was formed in the front center part of the tent 1. FIG. Thereby, it is possible to secure a large entrance / exit D, and the user can easily enter / exit the tent 1. For example, the user may open the outer end face plate 13 of the one outer cylinder portion 10 and enter / exit the tent 1 through the opening. However, if the end surface in the longitudinal direction of the tent 1 is an entrance, the user must go in and out of the tent 1 in a crawl and may be difficult to enter and exit. Therefore, like the tent 1 according to the present embodiment, the entrance D is preferably provided on the front side of the tent 1.

  Furthermore, in the tent 1 according to the present embodiment, the outer cylindrical portion 10 and the intermediate cylindrical portion 20 are formed sufficiently shorter than the entire length of the tent 1, so that even if these lengths are slightly increased, Carrying and storing is not difficult. Therefore, the overall length of the tent 1 can be adjusted (changed) by increasing or decreasing the length of the outer cylinder part 10 or the intermediate cylinder part 20 in the left-right direction. Thereby, the tent 1 of the length according to a user's request and an installation place can be provided.

  Further, in the tent 1 according to the present embodiment, the left and right end portions of the intermediate cylinder portion 20 overlap the outer surface of the outer cylinder portion 10, so that the door portion 25 can be opened outward. Since the doorway 25 is flipped up so as to incline backward, the doorway D is completely opened, so that it is possible to prevent the door portion 25 from becoming an obstacle for a user entering and exiting the tent 1. Moreover, the total length of the tent 1 can be finely adjusted by changing the overlap amount of each outer cylinder part 10 and the intermediate cylinder part 20.

  Further, in the tent 1 according to the present embodiment, each outer cylindrical portion 10 is configured by connecting the outer bottom surface plate 11 and the two outer side surface plates 12 in a substantially triangular shape. Similarly, the intermediate cylinder portion 20 is configured by connecting an intermediate bottom plate 21 and two intermediate side plates 22 in a substantially triangular shape. Thereby, the tent 1 can be manufactured easily and inexpensively without subjecting the corrugated board to complicated processing.

  Further, in the tent according to the present embodiment, since the extending piece 23 is disposed between the front end portion of the door portion 25 (the lower end portion in the closed state) and the installation surface GL, the front end portion of the door portion 25 is installed. There is no direct contact with the surface GL. Thereby, for example, when the tent 1 is installed outdoors, it is possible to prevent dirt such as dirt and sand from adhering to the distal end portion of the door portion 25. Although illustration is omitted, with the door portion 25 closed, the extension piece 23 is bent upward at the intermediate ruled line 21A, and the lock piece cut into the extension piece 23 is inserted into the operation hole 24 of the door portion 25. It is good also as a structure pushed in. Thereby, the door part 25 can be locked. In addition, although not shown, a padlock or the like may be attached to a penetrating piece that penetrates the operation hole 24 from the inside of the tent 1 with the door portion 25 closed. In the tent according to the present embodiment, the intermediate bottom plate 21 and the extending piece 23 are integrally formed, but not limited to this, the intermediate bottom plate 21 and the extending piece 23 are separately formed, You may connect with adhesive tape T etc.

  Further, in the tent 1 according to the present embodiment, the outer cylindrical portion 10 and the intermediate cylindrical portion 20 are assembled in a cylindrical shape having a substantially equilateral triangular cross section. Thus, the tent 1 that is lightweight and resistant to deformation can be configured by forming the outer cylinder part 10 and the intermediate cylinder part 20 as truss structures. Further, the outer cylinder part 10 and the intermediate cylinder part 20 are folded into compact storage shapes S1, S2. Thereby, the operator can carry easily the outer cylinder part 10 and the intermediate | middle cylinder part 20 which were deform | transformed into storage shape S1, S2. Moreover, the storage space of the tent 1 can be reduced by deforming the outer cylinder portion 10 and the intermediate cylinder portion 20 into the storage shapes S1 and S2.

<First and second modified examples>
In the tent 1 according to the present embodiment, the two outer cylinder portions 10 and the one intermediate cylinder portion 20 are provided, but the present invention is not limited to this. The tent 1 only needs to include a pair of outer cylindrical portions 10 and at least one intermediate cylindrical portion 20. For example, as shown in FIG. 10, the tent 2 according to the first modification may include two outer cylindrical portions 10 and two intermediate cylindrical portions 20. In this case, the two intermediate cylinder portions 20 are arranged side by side without a gap without overlapping each other. The left end portion of the left intermediate tube portion 20 overlaps the left outer tube portion 10, and the right end portion of the right intermediate tube portion 20 overlaps the right outer tube portion 10. Further, for example, as shown in FIG. 11, the tent 3 according to the second modification may include two outer cylindrical portions 10 and three intermediate cylindrical portions 20. In this case, the center intermediate cylinder part 20 is formed to have the same size as the outer cylinder part 10, and both left and right end parts of the center intermediate cylinder part 20 overlap the insides of the other two intermediate cylinder parts 20. In addition, although illustration is abbreviate | omitted, the center intermediate cylinder part 20 may be formed larger than the other two intermediate cylinder parts 20, and may overlap with the outer side of the other two intermediate cylinder parts 20. FIG.

<Third Modification>
