Abstract

(57) [Summary] [Purpose] To make the tent frame lightweight. [Structure] The roof frames 18, 20, 22 are made of an aluminum alloy. It is suitable to use JIS No. 6061 as the aluminum alloy. Since this aluminum alloy has a specific gravity of 2.70 and iron has a specific gravity of 7.87, a weight reduction of about 66% can be achieved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a tent frame.

[0002]

[Prior art]

 As is well known in the art, there are various types of tents that are in use. FIG. 1 shows an example of a frame for a tent called a so-called lodge tent. This tent frame includes a roof side frame, that is, a plurality of roof frames 18, 20, 22; a leg side frame, that is, a plurality of leg frames (also referred to as side wall frames) 10 and 14; A connecting member (for example, a wire) 32 is provided, and each frame connected by the connecting member is connected by a connecting member to be assembled. The outer tent and inner tent are attached to this assembled frame to complete the basic tent construction.

[0003]

[Problems to be solved by the device]

 However, since this conventional tent frame is made of steel (steel) on both the roof side and the leg side, the weight of the entire tent frame is heavy, which hinders transportation of the tent after or before tent construction. I had to come. In addition, the roof side frame was made of iron when it was set up, so it was heavy, and often the setup was not successful.

An object of the present invention is to reduce the weight of a tent frame.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, according to the present invention, in a tent frame having a roof side frame and a leg side frame, the roof side frame is made of aluminum alloy and the leg side frame is made of iron. Is characterized by.

[0006]

[Action]

 Aluminum alloys have a lower specific gravity than iron. Therefore, when a single tent frame with the same diameter, length and thickness is formed, the aluminum alloy material will be lighter than the iron material. Therefore, the weight of the tent frame itself can be reduced.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the example shown in FIG. 1, for example, the roof frames 18, 20, 22 are all made of aluminum alloy. On the other hand, the leg frames 10 and 14 are made of iron as in the conventional case. Although the roof side frame is made of aluminum alloy like this, considering the constructed tent, it has sufficient strength against rainwater. The leg side frame is made of iron because the strength of the constructed tent itself against the cross wind is taken into consideration, and if the leg side frame is made of aluminum alloy, the strength is uncertain.

The type of aluminum alloy used is not limited, but it is preferable to use an aluminum alloy having an alloy number 6061 defined by JIS standard. The components and specific gravity of this alloy are disclosed, for example, in "Aluminum Handbook", 4th edition, pages 15 to 16 and 190, published by Japan Institute of Light Metals. According to this document, the specific gravity of aluminum alloy is approximately 2.70, and the known specific gravity of iron is approximately 7.87. Therefore, even if it is simply calculated, a pipe of the same diameter and the same wall thickness can be obtained. It can be seen that the weight of both materials formed with both materials is about 66% lighter in the tent frame using aluminum alloy instead of iron.

In addition, as an example, it is preferable that the diameter of each frame of the aluminum alloy roof side frame is 19φ and the diameter of the iron frame is 19φ or 22φ.

Since the roof side frame is made of aluminum alloy, it is preferable that the connecting members for these frames are made of a material softer than the aluminum alloy, for example, a plastic material. This is to prevent damage to the aluminum alloy frame.

In the above-described embodiment, one kind of lodge tent has been described as an example, but this is merely an example. This invention applies not only to other types of lodge tents, but also to other types of tents if the tent frame can be divided into roof side and leg side frames. It is also suitable to be applied to frames.

[0013]

[Effect of device]

 As is clear from the above description, according to the tent frame of the present invention, since the individual frames of the roof side frame themselves are lightened, the individual frames of the tent frame are more weighted than the case of the heavy iron frame. It is easy and easy to handle, so it is easy to set up when setting up a tent. In addition, the lighter tent frame has the advantage of making it much easier to transport the tent itself.
