Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a frame for constructing a relatively large tent, and particularly to a frame for a tent that does not require a rigid girder even if the span is large.

(Prior Art) A conventional tent used to construct a temporary roof outdoors usually consists of assembling a large number of rods, and then attaching a membrane or the like made of a flexible material to the upper side of the frame formed by the rods. Many of them are formed by attaching them. In this type of tent, a large number of rods as described above must be erected vertically and firmly, so a member is required to support each rod from the side. Such members include bars or lobes that are arranged diagonally with respect to the upright bars, but these require a considerable amount of space because they need to be arranged diagonally. Therefore, if a large number of tents of this kind are set up close together, the diagonal members such as the robes mentioned above will become intertwined, and if the robes etc. become intertwined, it will be dangerous to use the tent. . If this is not enough and there is no place to diagonally extend support members for supporting each rod, it will be impossible to erect such a tent.

To prevent this from happening, if you want to erect just one large tent, you will have to prepare and erect a considerable number of rods. However, if there are a large number of rods, it becomes a difficult task to transport them, making it impossible to take full advantage of the advantage of this type of tent, which can be formed whenever and wherever needed. be. Further, when setting up such a large tent, the number of personnel required for the work is usually 5 to 10 people. The large number of people required means that the tent cannot be assembled easily. This also applies to the removal work of the large tent.

As the tent gets bigger, that problem becomes more and more important.

In other words, even if the problem of transporting the multiple rods that support the tent that forms the roof can be solved, the tent itself will be quite large, so a framework must be constructed that can sufficiently withstand its weight. Of course. Moreover, it is also necessary to prevent the tent from being blown away even in strong winds. It is nearly impossible to easily construct a tent that can sufficiently withstand these weights and strong winds, and the inventors have not found any tent in the prior art that can handle this.

In addition, a so-called air dome has also been developed as a relatively large tent, which surrounds a certain space with a flexible material, supplies pressurized air into the space, and has no pillars at all. However, since the pressure across the width of such an air dome must be maintained at a constant level, it is not only difficult to carry in and out materials by truck, etc. while taking air leakage into account, but also because air domes are constantly kept in a constant state. Naturally, equipment to supply this will be required. Further, such equipment is normally operated using electricity, but the air dome cannot be erected in a place without such a power source.

Therefore, the inventor has developed a tent that can sufficiently withstand the ffEQ and strong winds of a tent that serves as a roof as a relatively large tent.
Moreover, as a result of intensive research to develop a tent frame that is easy to transport and assemble, we have found that if you have a large tent, there is no need to consider getting in and out from all sides. The present invention was completed based on the new finding that if the center of gravity of the body is lowered, there is no need to support the pillar member from the direction of construction.

(Problems to be Solved by the Invention) The present invention has been made based on the above-mentioned circumstances, and the problems to be solved are the difficulties in transporting, setting up, and dismantling conventional large tents. be.

The purpose of the present invention is to make it possible to easily transport, set up, and take down the tent even when it is relatively large, and to make it sufficiently strong to withstand the weight and strong winds. To provide a frame for a tent that is durable and does not require any other members around it.

(Means for solving the problems) The means taken by the present invention to solve the above problems are as follows:
This will be explained with reference to FIGS. 1 to 5, which correspond to embodiments.

``A pair of left and right foundation frames (lO
), and a support member (20
), a pair of front and rear beam members (30) that are connected at a connecting part (21) formed at the end of each of these support members (20) to form a beam part, and each of the base frames (lO) and A support member (40) connected between the support members (20) and made expandable and retractable with respect to at least one of the base frame (lO) or the support member (20), and a support member (40) connected between the support members (lO) and the support members (lO). This is a tent frame (too) J characterized in that it is constituted by a flexible membrane support member (50) provided therein.

That is, the tent frame (100) according to the present invention includes a total of four base frames (10), a total of four wooden support members (20) connected to each of these base frames (10),
A total of two beam members (30) connected between these pair of support members (20), each base frame (10) and the support member (
20) in an expandable and retractable manner through their insertion holes (42), and a membrane support member (50) stretched between both beam members (30) facing each other. It is composed of When the tent frame (10G) is assembled with these constituent members, the membrane (60) constituting the roof can be firmly supported and fixed, and the tent frame (10G) can be firmly supported and fixed.
100) without any unnecessary objects.

(Aspects of operation and use of the invention) By adopting the above-mentioned means, the present invention has the following effects, but this effect can be achieved by the method of assembling and using the tent frame (100). I will explain this step by step in detail.

First, the tent frame (100) includes each base frame (lO
), support member (20), beam member (30), support member (4
o) and the membrane support member (50), it is possible to implant each member into a truck or the like in a disassembled state. In this case, in this embodiment, the outer shape of each base frame (10), support member (20), and beam member (30) is square, and the size is the same. , there is less dead space in the loaded state.

After each member is transported to the site, each base frame (10) is positioned. In this embodiment, each base frame (10) has a rectangular shape as described above, so as long as the 21 locations are in approximately the original state, it is sufficient to simply place them as they are.
In addition, in the foundation frame (10) according to the present example, the foundation frame (10) has a bar (I Ia) and a bar (Ilb).
A considerable space is constructed by the foundation frame (lO
), even if there is something that gets in the way of installing a stone, etc., it can be easily avoided, and there is no need to proactively level the installation site. . In other words, the installation location may be, for example, a grassy area. Then, each of these foundation frames (1
0) is installed by forming a pair of base frames (10) facing each other so that these pairs are parallel to each other with a certain distance between them.

Each foundation frame (10) installed at the appropriate location as described above
are connected by respective connecting portions (I2) facing each other. In this case, since the connecting plate (12a) constituting each connecting part (12) is fixed at right angles to the base frame (10), both connecting parts (12) cannot be connected to each other. Accordingly, a set of base frames (lO) automatically forms a straight line state.

After doing this, connect the other end of each foundation frame (10) (
l]) with the support member (20). This connection is performed using a connecting bolt (1:la) inserted through the other end connecting portion (13). Thereby, each support member (20) is rotatably connected to the upper frame (10). Thereafter, for each of these support members (20), each support member (40) is connected to its support plate (two).

Next, a beam member (30) is placed between each connecting portion (21) of a pair of left and right pillar members (20), and the beam member (30) is fixed to each pillar member (20). do. In this fixing work, each foundation frame (10) and beam member (3
Work while making adjustments for the final positioning of item 0). After each connecting part (21) has been erected, each member has a position of 2! This is because the adjustment work becomes difficult. Furthermore, the connection part (2 of each support member (20) is connected to the support member (4).
0) are connected, and a predetermined number of membrane support members (50) are connected to each beam member (30).

In order to use the tent frame (+00) as a tent, it is necessary to attach a membrane (60).
60) is carried out in this state where each support member (20) is not yet erected. In other words, the tips of each support column member (20) are located downward as shown by the imaginary lines in FIG. 1, and the tips are close to each other. This is because it is possible to perform various types of work on the respective pillar members (20) and beam members (30) on the installation polished surface.

In this state, the membrane support member (50) stretched between the beam members (30) is covered by the membrane (60), and a position is placed on the beam member (30) side of the membrane (60). The ends are connected by lobes, etc. Therefore, it is necessary to provide a large number of eyelet holes on the periphery of the membrane (60) through which the connecting ropes can be inserted. Each foundation frame (10) is constructed by connecting bars (lla) and bars (llb) to each other, and each support member (zO) and beam member (30) has a However, since it has the same structure as the upper underframe (10), there is a sufficient insertion point for the connecting lobe for the membrane body (50).
), each upper underframe (lO), column member (20) and beam member (
30) can be easily connected.

After doing the above, each support member (20) is erected using a tow truck or the like. When each support member (20) is erected at a certain angle, insert the insertion hole (42) at the lower end of each support member (40) connected thereto into the support plate (14) on each base frame (10) side. The provided screw member (4
1). Of course, in this case, the positioning member (43) screwed onto the screw member (41) should be positioned at the lowest end, and the fitting between each support member (40) and the screw member (4I) When the process is completed, each positioning member (4
3) and adjust the angle while pushing up each support member (40) by the required amount. This angle adjustment can be easily done by observing the expanded state of the membrane body (60), and it is also possible to adjust the tension on the membrane body (50) as described above. The tent frame (10G) is completed to support the membrane (60). In other words, each foundation frame (lO
), the center of the tunnel is kept low, and an opening is formed 1 meter behind it through which trucks and the like can freely enter and exit. Further, in the tent frame body (100) that has been assembled in this way, as shown in FIGS. 1 and 2, no members protrude from the left, right, front, and rear sides. In addition, the tent frame body (+00) may be implemented so that its front and rear openings are also covered by another membrane body (60), or this cover may be implemented by covering the above-mentioned pillar member (20). ) before erecting is convenient for work.

Of course, the operation for removing the tent frame (100) may be performed in the reverse order to that described above.

Next, the present invention will be explained in detail with reference to embodiments shown in the drawings.
