Description

  The present invention relates to a foldable tent provided with a beam material that operates in a scissors shape with respect to a pillar member via a connecting member, and particularly relates to a large dormitory foldable tent that can secure a wide internal space.

  In the case of a so-called one-touch type tent in which a beam material is folded in a scissors shape and a large tent in which the number of column members is 6 or more, a frame structure as shown in FIG. 6 has been used, for example. The conventional folding tent 111 has six column members 112 and six beam members 113 that connect the column members 112 to each other. An end joint 114 is attached to the top of the column 112 standing on the ground surface, and a slide joint 115 that can move in the vertical direction is mounted below the end joint 114. 114 and the slide joint 115 rotatably support one end portion of the diagonal member 116 constituting the beam member 113.

  In addition, a hinge joint portion 117 for connecting the left and right diagonal members 116 by pin connection is provided at the center of the beam member 113, and roof link members 118 are respectively attached from the hinge joint portion 117 toward the center of the tent. A central column 119 for supporting a central portion of a awning (not shown) is disposed at the central portion. The tent was attached to the frame structure from the top.

  Since the beam member 113 and the roof link member 118 are all pin-coupled and can be folded while operating synchronously in a scissor shape, the column members 112 are mutually connected during use. If it is separated from each other, the entire skeleton is expanded. Further, when the column material 112 is brought close to each other during storage, the entire frame can be contracted.

However, since the roof link member 118 connected to the center of the beam member 113 is disposed at the same height as the beam member 113, there is a drawback that the use of the internal space of the tent is limited. For example, when the column height is only 2.3 m, the lower end of the center column 119 has a height of 2 m, and the ceiling part is low and a feeling of pressure is felt. Therefore, as a foldable tent that can secure a wide internal space of the tent, for example, there are conventional techniques as shown below.
Registered Utility Model No. 3058526

  As shown in FIG. 7, this foldable tent connects column members 22 erected at the four corners, and is arranged in the direction of the column member 22 diagonally opposed to the four beams 23 operating in a scissor shape. The roof link member 24 gathers toward the center of the tent, and each beam member 23 and the roof link member 24 are rotatably connected to the connecting member 25 attached to the column member 22.

  At the center of the tent, a support 26 is attached to the converging point of the roof link member 24, and a central column 27 is accommodated in this, and a awning (not shown) is supported by the head.

  In the case of the collapsible foldable tent 21 that projects the roof link member 24 from the column member 22, a horizontal member exists on the lower surface of the building member 24a to be gathered only by reinforcing the cane 24b at the corner. This has the advantage that the internal space of the tent can be used widely.

  However, in the case of the dormitory folding tent 21, the ridge material 24a is supported only by the corner cane 24b. Therefore, in the case of a large tent in which the interval between the column members 22 is large, the ridge material 24a is bent. There was a risk of falling.

  Further, since the central column 27 was accommodated in the cylindrical support 26 that constitutes the concentrating point of the building material 24a, a column having a high height could not be set. Therefore, the tent to be installed is flat, and there is a possibility that the tent between the building materials 24a may hang down due to poor water drainage during rain, resulting in a pool of water.

  For this reason, especially in the case of a large tent with six or more column members, a foldable folding tent is not applied, and a conventional frame structure with a low ceiling is common. .

  The present invention has been made to solve the above-mentioned problems of conventional large foldable tents and dormitory foldable tents, and the ridge material bends even in a frame structure with a high ceiling. The purpose of the present invention is to provide a large foldable folding tent that can be installed at a high height without the fear and can secure a sufficient gradient of the awning.

  In order to solve the above-mentioned problems, the dormitory foldable tent of the present invention includes a column material standing at the apex position of a regular 2n square (n is an integer of 2 or more), and a column material adjacent to each column material. A beam member that operates in a scissor shape via a connecting member, and a roof link member that is arranged in the direction of the column material facing diagonally and is pivotally connected to the connecting member and collects building materials toward the center of the tent. In the dormitory folding tent in which a support for the central column supporting the awning is attached at the center of the tent, the building material is provided with a folding point that can be folded downward at an intermediate portion, and the support is An upper cylinder body that is provided in the building material concentrating part and that passes through the central column, a cradle that holds the lower end of the central column, and a cradle that is pivotally attached to the bending point of each building material and an intermediate position of the collecting unit A support member is provided.

  The connecting member is composed of an end joint that attaches to the top of the column member, and a slide joint that is mounted below and is movable in the vertical direction, and supports the beam member and the roof link member so as to be rotatable. By moving the joint up and down, the mounting angle of the beam member and the roof link member is changed. The building material is pivotally connected to the end joint and supported by a wand connected to the slide joint.

  Each of the upper cylinder body and the cradle is provided with a plurality of building material connecting portions or cradle support member connecting portions protruding from the outer surface. The central strut is supported by a cradle suspended from the building material, and its lower end is held, and the middle part is supported by the upper cylindrical body, so that the standing state is stable and the rising part protruding from the building material can be enlarged. it can.

  In addition, since the combination of each building material, the cradle support member, and the central column has a three-dimensional truss structure, the building material collecting portion is not easily deformed even when a load is applied.

  The bending point of the dormitory foldable tent according to claim 2 is provided with a connector for projecting plate bodies on both sides, and is located at the center between the adjacent plate bodies of the adjacent building materials. A horizontal member that can be folded is provided.

  The bending points, which are the middle part of the building material, are connected and reinforced with horizontal members. The combination of building materials and horizontal members also forms a three-dimensional truss structure.

  The dormitory foldable tent of the present invention is provided with an upper cylindrical body, a cradle and a cradle support member as a support for the central column, so that the standing state of the central column is stable and protrudes from the building material. Can be bigger. Therefore, a sufficient slope of the awning can be secured, and there is no risk of poor drainage during rainfall.

  In addition, since the combination of each building material, the cradle support member and the central column has a three-dimensional truss structure, it is difficult to be deformed even when a load is applied, and the building material may be bent even in a frame structure with a high ceiling. Absent.

  Since the foldable folding tent according to claim 2 connects and reinforces the bending points with a horizontal member, it becomes a solid three-dimensional truss structure, and even a large folding tent can be used for wind loads, etc. It becomes a stable frame structure that can be countered.

The connecting member 5 to be attached to the column member 2 is divided into an end joint 6 and a slide joint 7, and beam support plates 6 b in the direction of the column member 2 adjacent to the frame portions 6 a and 7 a for accommodating or inserting the column member 2, respectively. , 7b. The beam support plates 6b and 7b face a pair of plates, insert the end of the diagonal member 3a constituting the beam member 3 into the gap, and insert a pin or the like into the pin hole opened on the plate surface. Support movably.

  A building material support plate 6c and a cane support plate 7c are respectively provided adjacent to the beam support plates 6b and 7b. The building material support plate 6c and the cane support plate 7c also face each other a pair of plates, insert the ends of the building material 4 or the cane 4a into the gaps, and penetrate the pins etc. into the pin holes established on each plate surface And is supported so as to be rotatable.

  As shown in FIG. 3, a positioning pin 12 is attached to the slide joint 7 so that it can be pulled out below the beam support plate 7b and the cane support plate 7c on the outer surface of the frame portion 7a. This pin 12 is inserted into a pin hole (not shown) drilled in the column member 2 to fix the height of the slide joint 7. Further, in the beam support plate 7b and the building material support plate 7c, the support plate on the side receiving the tip of each inserted pin or the like may be used also as an adjacent support plate.

  Next, details of the bending points of the building material will be described with reference to FIG. FIG. 4 is a perspective view of the building material bending point. The building material 4a is divided at a bending point 4d. Between the plate members 13a facing each other in the adjacent building material 4a, the bending point 4d is provided with a connector 13 projecting plate members 13a on both sides. A horizontal member 11 is installed on the side. The plate body 13a also faces a pair of plates, inserts the end portion of the horizontal member 11 into the gap, and supports the pin holes through the pins and the like so as to be rotatable. The horizontal member 11 is also divided at the center, and is connected so as to be foldable upward by a connector 11a.

  Next, details of the support will be described with reference to FIG. The support 10 is provided at a concentrating portion of the building material 4a, and includes an upper cylindrical body 10a that passes through the central column 9, a receiving base 10b that holds the lower end of the central column 9, and a bending point 4d and an upper portion of each building material 4a. A cradle support member 10d that is rotatably attached to a middle position of the cylinder 10a via a connector 10c is provided.

  The upper cylindrical body 10a and the cradle 10b are each provided with a plurality of building material connection portions 10e or cradle support member connection portions 10f on the outer surfaces thereof, and fasten the wing material 4a or the cradle support member 10d in a pivotable manner.

  The center column 9 is composed of an inner tube 9a positioned above and an outer tube 9b positioned below, and urges the inner tube 9a upward by a spring body 9c housed inside the outer tube. The central support column 9 is configured with a combination of lengths appropriately so that the double pipe is not separated when the framework structure is folded. When the awning 8 is mounted on the round awning contact tool 9d attached to the top of the inner tube 9a, the awning 8 is pushed up by the action of the spring body 9c, and the tension is strengthened.

  Each of the building materials 4a, the cradle support member 10d, the central column 9, and the horizontal member 11 are connected to each other to form a three-dimensional truss structure, so that even if a load is applied from the awning 8, deformation is difficult. That is, this frame structure reinforces the roof link member 4, and the load acting on the central support column 9 is distributed to each member of the three-dimensional truss.
