Abstract

PROBLEM TO BE SOLVED: To solve the problem in indication that there is a danger of causing a radio wave hindrance in radio control of a drone due to being conventionally made of metal, since a conventional skeleton requires labor for assembling besides being nonflexible and heavy due to being a metallic framework, and canot be installed in various places such as slope land and an up-down site besides being narrow in space, and since a conventional net cannot be easily removed due to being a covering method, and is not easy in removal when wind is likely to become strong.SOLUTION: The problem is solved by suspending a cage molding a net by an auxiliary rope, by constituting a structure of a baseplate and a column holding tool corresponding to an inclination, a flexible column and a structural rope. For a structure using one unit having decided length×breadth×height as a base, assembling is executed while constituting the unit by four flexible columns, a structural rope stretched on the four sides for supporting the columns, and a support material. The structure is set up in a required extent, and the formed net is suspended therein to complete the cage.SELECTED DRAWING: Figure 1

(4) Even if two ropes are passed through the upper part of the support column, the nets are evenly lifted by lifting the central part and the end of the nets through a special pulley that is divided into two vertically, which forms the core of each pulley. The method according to (1) and / or (2) and / or (3) for stretching.
(5) A set for stretching a net including a base plate, a support holder, a support and a rope attachment, and a dedicated pulley, which is used in the method according to any one of (1) to (4).

Effect of the invention

The present invention makes it possible to easily install the support pillars in the vertical direction even in various places, compensate for the strain applied to the pillars by the ground or the net by the flexibility of the support pillars, and enable installation in various places with light weight.
In addition, a rope attachment that can rotate in the circumferential direction can be used to stretch a structural rope in the support direction. A special pulley is installed at the upper part of the column and the net height, and the central part and end part of the net are lifted to hang down. It is possible to reduce, and it is possible to pass two ropes through one pulley with a dedicated pulley, and it is possible to pull up each adjacent net when expanding. Since a unit whose length, width, and height are determined in advance can be easily assembled as a basic unit, it is possible to stretch a net flexibly applied to a required area. In addition, the method of the present invention has an effect that there is no risk of causing radio interference because the structure uses almost no metal.
