Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding framework in which a quadrangular framework is formed when unfolded, and more particularly to a folding framework that can be used in combination with a plurality of combinations to form a pillar or an outer frame of a temporary structure such as a tent.

[0002]

2. Description of the Related Art Conventionally, a tent installed in an outdoor event or the like has been formed by combining an entire frame with iron pipes. That is, a joint is attached to each pipe in advance, and a predetermined pipe is inserted into each joint,
A tent was constructed by attaching a cloth cover to the roof.

[0003] In addition, when a house is urgently needed in the event of a disaster, a prefabricated house is appropriately constructed.

[0004]

However, in a conventional tent made of iron pipe or the like, a roof tent is assembled on the ground, a waterproof tent is attached to the tent, and the roof attached to the tent is lifted to remove the roof from the roof. It was supposed to insert columns in the four corners and start up. Therefore, it is necessary for at least four people to set up the tent because the roof is lifted at the four corners. In addition, each pipe has a joint protruding in various directions, and even if it is disassembled and put together, it cannot be neatly housed.

Further, the conventional type tent using a pipe cannot be used as a house which is urgently needed in the event of a disaster because a wall member cannot be provided on the side surface. On the other hand, a prefabricated house requires a large amount of installation and is suitable for installation for several months to several years, but it is not practical because it takes time to install it if the required period is short. Furthermore, the prefabricated house has a problem that it takes time and labor to remove, store and move the prefabricated house after use, and a large storage space is required.

Means for Solving the Problems A support member having a bendable intermediate portion is provided in parallel with each of both end portions of two main members having substantially the same length, and the bend portion of the support member is fixed by a fixing mechanism. When fixed linearly and supporting the main member, a quadrangular framework is formed, while bending this support member from the bent portion allows the support member to be housed inside and folded so that the main members are stacked. Constructed a folding framework.

Further, the main member is formed with a connecting portion which can be connected to another main member of the folding framework. In addition, a reinforcing member such as a chain is attached diagonally.

The main member is preferably made of a material having a predetermined strength, such as an iron material or an aluminum material, and preferably has a U-shaped cross section. The two main members have almost the same length,
Face the open side of the U-shape.

The support member preferably has a U-shaped cross-section like the main member, and the width is a width that can be accommodated inside the main member.
The support member and the main member are rotatably connected by a pin or a hinge. The support member rotates from the inner side to the outer side of the main member so as not to open beyond the right angle to the main member. Further, by passing a chain or a rope on the diagonal line of the developed frame, the right angle between the main member and the support member can be firmly held. Further, a reinforcing member such as diagonal braces may be provided at the intersection of the main member and the supporting member at a right angle. By providing a chain or brace in this way, the right angle formed between the members can be firmly held, and the strength of the entire framework can be improved. Since it is difficult to use as a doorway if a diagonal chain is formed, it is preferable to use other things such as braces at the place used as a doorway.

The bent portion is provided substantially at the center of the support member, and as a fixing mechanism for fixing the bent portion, there is a mechanism for attaching an iron plate or a bar to the bent portion.

The connecting portion is formed by bending a plate material so as to be engaged with the U-shaped rising portion of the main member.
Alternatively, they may be connected by screws or the like. The connecting direction may be linear or right angle. Furthermore, pentagon, hexagon, etc.
You may connect and may comprise a polygon.

When connecting the developed frameworks and installing a tent, the length of the support member is adjusted to form a roof so that the angle of the apex is an appropriate angle, and a cloth material is stretched there. Configure. A roller may be provided at one end of the roof to facilitate movement of the roof. Further, a wall plate or the like may be attached around the connected frame to form a shed or a temporary house. Since the frame is a quadrangle and the periphery is a member made of metal, a highly durable structure can be easily installed. Furthermore, by changing the length of the main member as necessary, the width and depth of the entire structure can be adjusted appropriately. Further, the height can be adjusted by changing the length of the support member.

When pulled out from 6, the support member 6 becomes bendable. 14
Is a set screw for fixing the fixing plate 12 at an arbitrary position.

FIG. 2 shows a state in which the framework 2 is folded. When the support member 6 is folded in this way, the chain 7 is accommodated inside and the outer shape is the same as when the two main members 4 are combined.
When the upper main member 4a is pulled up from the lower main member 4b from the folded state, it gradually expands as shown in FIG.
When the support member 6 is made linear and the fixing plate 12 is inserted,
As shown in FIG. 1, chains 7 are stretched diagonally to form a quadrangular frame.

As described above, the frame 2 becomes compact when folded and is easy to store, store and transport, and is expanded to support the support member 6.
The frame 2 having high strength can be configured by fixing the. Further, various frame structures can be constructed by connecting a plurality of frameworks 2, and for example, a square structure can be constructed by four frameworks 2. Further, instead of the chain 7, brace or the like may be provided.

Next, an example of setting a tent using the frame 2 will be described.

The frame 1 of the tent is shown in FIG. Frame 1 is
Six frames 2 constituting the wall 3 and 4 constituting the roof 5
It is formed from the frame 2 of the platform. The six frames 2 constituting the wall 3 have the same shape, and the frame 2 constituting the roof 5 has a shorter length of the support member 6 than the frame 2 of the wall 3, and the roof 5 is When constructed, the roof top is at an appropriate angle. Also, all the frames 2 of the roof 5
The chain 7 is provided on the frame 2, and the frame 2 of the wall portion 3 is provided with the chain 7 on both side surfaces and one rear frame 2. The position where the chain 7 is provided is not limited to this, and may be the frame 2 at another position.
Further, an oblique reinforcing member may be provided between the upper main member 4a and the supporting member 6.

Next, the assembly work will be described. First, the wall portion 3 is constructed by using the six frames 2. For assembly, the lower main member 4b is connected in a rectangular shape using the connecting portion 32 shown in FIG. 6 to form the bottom surface. Next, framework 1 of 2
Expand (you can start anywhere). To deploy the framework 2, one worker pulls up the upper main member 4a, and the other one fixes the bent portion of the support member 6 in a straight line by the fixing mechanism 24. When the start-up of the first frame 2 is completed, the adjacent frames 2 are similarly started up and deployed, and the upper main members 4a are connected to each other. In this way, the rectangular walls 3 are formed by sequentially raising the six frames 2.

Next, the roof frame 2 is unfolded, and the unfolded frame 2 is connected two by two in a plane. Frame 2 of roof 5
Since one of the support members 6 is attached to the end of the main member 4, the support members 6 are located at both ends of the main member 4 and a rectangle is formed when two units are connected. Then, the frames 2 connected two by two are butted at the center and connected at a predetermined angle.
The connection is performed by screwing using the metal fitting 34 shown in FIG. 7 which is inclined at a predetermined angle. The formed roof part 5 is shown in FIG.

When the roof portion 5 is formed, the roof cloth material 20 is attached to the roof portion 5.
