【考案の詳細な説明】 本考案は防雪柵に関するものである。[Detailed explanation of the idea] The present invention relates to a snow fence.
従来、防雪柵は降雪が終ると毎年撤去していた
が、最近は防雪柵の需要の増加に伴つてその設置
数も増加し、従つて、撤去には多くの費用を要す
るようになつた。このために、最近は年間を通じ
て設置しておく定置式に変わつてきている。 Traditionally, snow fences have been removed every year after the snowfall has ended, but recently, as the demand for snow fences has increased, the number of snow fences installed has also increased, and removal has therefore become costly. For this reason, in recent years there has been a shift towards fixed types, which are installed throughout the year.
しかしながら、この定置式にも次に示すような
問題点がある。 However, this stationary type also has the following problems.

ことにより、景観の阻害を防ぎ、また自動車等の
運転者の圧迫感を除去し、更に日光が広げられた
防雪板間を透過することによつて日蔭を極小にす
るなど、いろいろの考案がなされてきた。 In other words, snow fences installed along the roadside remain in place even after the winter season, which obstructs the landscape and also creates a sense of pressure on motorists, impeding safe driving. Furthermore, the farmland is in the shade of the snow fence, which has a negative effect on the crops. In order to deal with these shortcomings, recently, after the winter period, each snow protection board that makes up the snow protection fence is lowered until it becomes horizontal, and the spacing between the snow protection boards is widened, so that the front view can be seen clearly through the snow protection boards. By making it visible, it prevents the landscape from being obstructed, eliminates the feeling of pressure on drivers of cars, etc., and minimizes shade by allowing sunlight to pass through the spread snow protection boards. Various ideas have been made.
しかしながら、日光の当たる角度によつては、
まだ、日蔭の生じることを防止することはでき

の設置が禁止されてもいる。 However, depending on the angle of sunlight,
It is still not possible to prevent the occurrence of shading, and no matter how horizontal the snow protection boards are, for drivers of cars, etc., the smaller the angle of view of the main pillars in front of them, the more they overlap. It can't be avoided that it starts to look like a wall and creates a feeling of oppression. Furthermore, on roads in national parks, etc., it is prohibited to install anything that obstructs the scenery during the summer.
