Description

【発明の詳細な説明】 この発明は、測量用のポールに関するもので、
従来測量用ポールは、補助器具を用いて目標点上
に立てていたため、相当の時間がかかつていた。[Detailed Description of the Invention] This invention relates to a surveying pole.
Previously, surveying poles had to be erected on target points using auxiliary tools, which took a considerable amount of time.

この発明は、目標上にポールを既略立てれば自
動的に鉛直が確保出来るようにしようとするもの
である。 This invention attempts to automatically ensure verticality when a pole is already erected on a target.

この発明を測量用ポールとして実施した実施例
を図面に基づいて説明すれば次の通りである。 An embodiment in which the present invention is implemented as a surveying pole will be described below based on the drawings.

水密な外側パイプポールの先端部の内側に
液体をみたした中に、自由に回転出来る取付部
浮力中心より重心が下に来るようにバランスウ
エートをもつた水密な内側パイプポールを余
裕巾をもつて装置したものである。 Fill the inside of the tip of the watertight outer pipe pole with liquid, and attach the watertight inner pipe pole with a balance weight so that the center of gravity is below the buoyancy center of the mounting part, which can rotate freely. The device was installed.

従つて外ポールを外ポールと内ポールの
余裕巾内に立てれば内側ポールは自動的に鉛直
に立つ。 Therefore, if the outer pole is erected within the margin between the outer and inner poles, the inner pole will automatically stand vertically.

この発明は以上説明したように従来のポールと
ちがい微調制の必要がなく、すばやく簡単に測量
用鉛直ポールとする事が出来る。 As explained above, unlike conventional poles, this invention does not require fine adjustment and can be quickly and easily made into a vertical pole for surveying.

がなく完全な鉛直を現示出来る測量用ポール。1 A ball joint that moves in all directions connects a watertight, buoyant inner pole that is thinner and longer than the outer pipe and has a lower end to the inner lower end of the outer pole to allow for extra space. This is a surveying pole that can show perfect verticality without the need for fine adjustment by simply providing general support to the extent that the free space does not collapse by filling the free space with liquid.
