Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an awning to be installed at the entrance of a mobile shelter equipped with communication equipment for protection from wind and rain, and particularly to the effect of electromagnetic wave interference on equipment installed in the shelter. About the lost awning.

[Conventional technology]

Generally, an awning for preventing wind and rain from entering the shelter when the door is opened is attached to the entrance of the moving shelter in which the communication device is mounted. Conventionally, this kind of awning is formed by weatherproof cloth or the like for the outer wall forming the awning for the purpose of being able to withstand wind and rain as described above, and also for the purpose of facilitating attachment / detachment to and from the shelter. ing.

[Problems to be solved by the invention]

The above-mentioned conventional awning is effective against wind and rain, but it is difficult to prevent electromagnetic interference due to external electromagnetic waves on the communication device in the shelter. That is, when a moving shelter is installed in a place where electromagnetic waves are distributed, when the door of the shelter is closed, the shielding effect of the shelter shields the electromagnetic coupling between the inside of the shelter and the outside of the shelter. In the open state, electromagnetic waves distributed outside the shelter enter the shelter through the entrance and exit of the shelter through the awning. As a result, there arises a problem that electromagnetic interference is given to the communication device mounted in the shelter and the normal operation of the communication device is impaired.

[Means for solving problems]

An object of the present invention is to provide an awning capable of preventing the influence of weather on a communication device in a shelter and the interference of external electromagnetic waves.

The outer wall of the awning of the present invention has a double structure of a weather resistant cloth and an electromagnetic wave absorbing cloth, and is configured to prevent the entry of wind and rain and electromagnetic waves into the awning.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

1 (a), (b) and (c) are respectively a plan view, a front view and a side view of the awning, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a awning shelter. It is a perspective view of the state where it was attached to.

As shown in FIGS. 1 (a) to 1 (c), the awning 1 is
One side surface is formed into a closed box shape, and mounting pipes 2 are provided above and below this opening.

Further, a door 3 is formed on one side wall of the awning 1 so that the door can be moved in and out of the awning 1.

The outer walls such as the side walls and upper and lower walls of the awning 1 and the door 3 all have a two-layer structure of a weather resistant cloth 4 and an electromagnetic wave absorbing cloth 5 as shown in FIG. The electromagnetic wave blocking action of the electromagnetic wave absorbing fabric 5 prevents the electromagnetic waves from entering the awning 1. For example, the weather resistant cloth 4 is formed of fibers having a waterproof effect, and the radio wave absorbing cloth 5 is formed of conductive fibers such as metal.

As shown in FIG. 3, the awning 1 includes the mounting pipes 2 mounted on mounting guides 12 provided above and below a door 11 for moving in and out of a shelter 10 for moving in which communication devices are mounted at spatial positions where electromagnetic waves are distributed. By inserting it, the door 11 is attached to the shelter 10 in a close contact state so as to completely cover the door 11.

Therefore, according to this structure, unless the door 3 of the awning 1 and the door 11 of the shelter 10 are opened at the same time, the shelter
Weather shelter 10 when opening and closing door 11 when entering and leaving 10.
It is possible to prevent the electromagnetic waves from entering the inside of the shelter 10 as well as to prevent the electromagnetic waves from entering the inside. As a result, it is possible to prevent electromagnetic wave interference exerted on the communication device mounted in the shelter.

Here, it goes without saying that the radio wave absorbing fabric in the present invention includes a thin film or a metal film formed of a conductive material.

[Effect of device]

As described above, according to the present invention, since the outer wall of the awning has the double structure of the weather resistant cloth and the electromagnetic wave absorbing cloth,
It is possible to prevent intrusion of wind and rain and electromagnetic waves into the awning, and to prevent the influence of weather on the communication devices in the shelter and the interference of external electromagnetic waves.
