Description

  The present invention relates to a foldable tent including a vertical member that can be attached to and detached from a column member via a connecting member, and more particularly to a foldable tent that can enhance resistance to wind loads.

  In general, a relatively simple small tent installed at an event venue, an athletic meet, a disaster prevention training command center, or the like is widely used as a foldable tent using a link member so that it can be easily assembled and removed. Such a foldable tent is constructed by standing and fixing a plurality of pillars, but it has a drawback that it is weak against wind loads, and unexpected accidents such as collapse due to unexpected gusts due to weather changes etc. There was a risk of occurrence.

  In order to enhance resistance against such wind loads, in conventional folding tents, pegs are driven into and fixed to the base plate of the pillar material, or weights are placed on the base plate. In addition, when there was a margin around the tent, branch lines such as wires and ropes were diagonally diagonally extended from the column heads to counter the wind load. Tent collapses due to gusts and the like are likely to occur in urban areas and school playgrounds, and this is probably due to insufficient branch line tension, insufficient pile driving, and insufficient weight loading.

By the way, as a conventional foldable tent with a measure against wind load, for example, there is a conventional technique as shown below.
Japanese Patent Laid-Open No. 08-232508 Japanese Patent Laid-Open No. 2005-180024 JP 2001-271516 A

  However, pasting the branch line around the tent obstructs traffic, and it is difficult to visually recognize the presence of wires and the like, and there is a high risk of tripping. In addition, in the case of branch lines, they must be installed around the tent in a point-symmetrical arrangement to maintain a balance with uniform tension, and the occupied area around the tent is wide, and the ground is limited to where pegs can be driven. In particular, in urban areas, it is not a very effective method for measures against wind loads in simple tents, because it is impossible to stake out due to paving such as concrete and asphalt.

  When the peg was not driven, the branch line was fixed mainly using a weight, but the weight load to counter the wind load is several tens of kilograms per place, so handling is quite troublesome. From this aspect, too, the reinforcement by the branch line was not adopted.

  On the other hand, when the weight is mounted on the base plate of the pillar material, there is a drawback that the space inside the tent is narrowed. In the first place, the reinforcement by such a method can endure even when the wind speed is 10 m, 20 m or more. It was extremely difficult to provide as much resistance as possible.

  The present invention has been made to solve the above-described problems of conventional folding tents, and can enhance resistance to wind loads without eroding the space inside the tent, and The purpose of the present invention is to provide a foldable tent that can secure the safe traffic as much as possible and can cope with the case where the occupied area around the tent is limited.

In order to solve the above-described problem, a foldable tent of the present invention is provided with a plurality of pillar members, a side link member that connects adjacent pillar members, and a projecting portion that faces inward from a connecting portion of the side link members. In a foldable tent comprising an internal link member that connects the connecting portions, a roof post attached to the side link member or the connecting portion of the internal link member, and a removable awning that covers the roof post and the side link member, The column member includes a vertical member, a diagonal member, and a bottom member, and a reinforcing assembly in which an intersection member capable of mutual connection and detachment is provided at each of the triangular end portions, and the vertical member of the reinforcing assembly. It has the connection member connected so that attachment or detachment with respect to a pillar material is characterized.

  The reinforcement assembly can support the push-pull load acting on the column material by the wind load.In the leeward, the diagonal material as the reserved column mainly resists the push load, and on the windward the entire reinforcement assembly. To counter the pulling load. For this reason, take measures to prevent the bottom material from rising. For prevention of lifting, fixing by a peg or loading of a weight is appropriately selected according to the installation situation.

  The reinforcing assembly may be provided on each column member or may be omitted as appropriate. When one side is omitted for traffic or the like, the rear side reinforcement assembly is used to resist wind loads. Therefore, an asymmetric arrangement is also possible.

  Due to the presence of the intersection member, the diagonal member and the bottom member can be appropriately removed or attached. That is, it is possible to connect only the vertical member to the column member at normal times for traffic, etc., and to take measures against a steep wind load only when necessary.

  The connecting member is provided at a plurality of locations in order to transmit the load acting on the column member to the vertical member, and any of the connecting members can be attached after the tent is set up.

  The intersection member of the foldable tent reinforcing assembly according to claim 2 has a pin coupling that allows changing the intersection angle of each side member, and each side member is an assembly member whose length can be adjusted. It is what.

  The triangular shape of the reinforcing assembly is configured to be freely deformable in accordance with the height of the pillar material, the size of the area of the peripheral room, and the like. Each side member may be an assembly member formed by an outer and inner pipe, or may have a structure in which plate members and mold members are appropriately combined.

  The connecting member of the foldable tent according to claim 3 includes a shaft member head projecting from the column member side, and a receiving portion that is attached to the vertical member and detachably fits the shaft member head. It is characterized by.

  After the shaft member head portion is inserted, the receiving portion has a shape that is fitted upward or downward, and connects the column member and the vertical member with one touch. This connecting member may be provided at one place in each reinforcing assembly, and after the simple connection, the other parts are fastened.

  The vertical member of the foldable tent according to claim 4 is characterized in that it has a structure capable of fixing a leg portion of a posting frame formed in a gate shape.

  The posting frame is a signboard of a banner that displays arbitrary characters and designs such as the name of a tent, and its legs are fixed to the reinforcing assembly. Since the signboard is heavily subjected to wind loads, unless the support is strengthened, the tent will collapse. Conventionally, since the signboard is directly attached to the pillar material, the wind load acting on the signboard acts on the pillar material head, which is quite dangerous.

  In the present invention, since the structure is fixed to a vertical member separate from the column member, the safety level is increased. It is desirable that the frame leg and the vertical member have the same structure. For example, when a pipe is used for the vertical member, the leg is also a tube that can be inserted and fixed thereto.

  The vertical member holding the posting frame may be in a state where the diagonal member or the bottom member is removed, or may be attached to a triangular reinforcing assembly.

  In the foldable tent of the present invention, the triangular reinforcing assembly is connected to the column member, so that the resistance against wind load can be enhanced without eroding the space inside the tent. Since the reinforcement assembly is clearly visible, unlike the branch line, the risk of unintentional collision is reduced. Further, since the pushing and pulling load can be supported by one reinforcing assembly, an asymmetric arrangement is also possible. For this reason, safe passage around the tent can be secured, and it is possible to cope with a case where the occupied area around the tent is limited.

  Since the vertical member of the reinforcing assembly is detachably attached to the pillar member by the connecting member, it can be attached after the tent is set up. In addition, since an intersection member capable of connecting and detaching the vertical member, the diagonal member, and the bottom member is provided, the diagonal member and the bottom member can be removed and attached as appropriate.

  The foldable tent according to claim 2 can be freely deformed according to the height of the column member, the size of the surrounding space, etc. because the crossing angle and the length of each side member of the reinforcing assembly can be adjusted. .

  In the folding tent according to the third aspect, the shaft member head protruding from the column member side as the connecting member is detachably fitted to the receiving portion of the vertical member, so that the column member and the vertical member can be connected with one touch.

  Since the leg part of the posting frame body formed in a gate shape can be fixed to the vertical member, the folding tent according to claim 4 is reinforced in resistance to wind load even when a signboard is posted.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
