Description
【考案の詳細な説明】
本考案は、JIS規格の締付ねじを有する三脚と、
シフト付セオドライト用の三脚とのいずれにも取
付けることのできる測量機に関する。[Detailed description of the invention] The invention consists of a tripod having a JIS standard tightening screw,
This invention relates to a surveying instrument that can be attached to either a tripod for a theodolite with a shift.
従来、JIS規格の「Ｗ5/8インチねじ」が、三脚
取付用ねじとして、測量機本体の底板に設けられ
ているのが一般的である。 Conventionally, a JIS standard "W5/8 inch screw" has generally been provided on the bottom plate of the surveying instrument body as a tripod mounting screw.
一方、三脚に固定した底板に対し本体が水平移
動する、いわゆるシフト付きセオドライトと呼ば
れている測量機が近年多用されるようになつた
が、このものは本体が移動しても地上の測点の観
察光路を確保するために、三脚取付用ねじの径を
「Ｗ5/8インチねじ」よりかなり大きくしている。 On the other hand, surveying instruments called so-called shift theodolites, in which the main body moves horizontally relative to a bottom plate fixed to a tripod, have come into widespread use in recent years; In order to secure the observation optical path, the diameter of the tripod mounting screw is made considerably larger than the ``W5/8'' screw.
従つて、「Ｗ5/8インチねじ」を有する測量機
と、シフト付きセオドライトとは、別々の三脚を
用意しておかなければならないという欠点があつ
た。 Therefore, there was a drawback in that separate tripods had to be prepared for the surveying instrument with the "W5/8 inch screw" and the theodolite with a shift.
測量作業では、レベルとセオドライトとを併用
する場合が多いのであるが、便利さを重複してシ
フト付きセオドライトを選択すると、山等での測
量作業において、それぞれ専用の三脚を持ち歩か
なければならないという重労働を測量者に強いる
ことになつた。 In surveying work, a level and theodolite are often used together, but if you choose a theodolite with a shift for convenience, you will have to carry a separate tripod for each when surveying in mountains, etc., which is a heavy labor. surveyors were forced to do so.
一方、トランシツト・レベル兼用の三脚が実開
昭52−161654号に開示されている。 On the other hand, a tripod that can be used both as a transit level and as a tripod is disclosed in Japanese Utility Model Application No. 52-161654.
しかしながらこのものは、レベル取付け用の雄
ねじとトランシツト取付け用の雄ねじとを軸方向
にずらせて形成した定心桿を用いているために、
トランシツトの代わりにシフト付きセオドライト
を用いる場合には、定心桿に設けたレベル取付け
用の雄ねじがシフト付きセオドライトの測点観察
光路（視野）を制限してしまうため、シフト付き
セオドライトのシフト機能を十分生かすことがで
きなかつた。 However, because this product uses a centering rod in which the male thread for level mounting and the male thread for transit mounting are shifted in the axial direction,
When using a theodolite with a shift instead of a transit, the male screw for level attachment provided on the centering rod limits the observation optical path (field of view) of the theodolite with a shift, so the shift function of the theodolite with a shift must be I couldn't make full use of it.
そこで本考案の目的は、シフト付きセオドライ
トとの間で三脚を共用できることは勿論、シフト
付きセオドライトのシフト機能を何ら損なうこと
のない測量機の提供にある。 Therefore, an object of the present invention is to provide a surveying instrument that can share a tripod with a theodolite with a shift, and does not impair the shifting function of the theodolite with a shift.
以下、図面に示した実施例に基づいて本考案を
説明する。 Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

A female tightening thread 8 formed on the centering rod 7 of a well-known tripod for a theodolite with a shift as shown in FIG. 3B is screwed into the center rod 7. Here, the outer diameter of the cylindrical protrusion with the female thread 3 formed on the inner periphery is
When l 1 and the inner diameter of the centering rod 7 are l 2 , l 1 < l 2 . As is well known, the hollow part of the centering rod 7 is used as a light conduit for passing an observation optical path for measurement.

作が必要であつて、本願考案の力が勝れている。 As described above, according to the present invention, it is possible to obtain a surveying instrument in which a JIS standard "W5/8 inch screw" and a screw for a theodolite with a shift are formed concentrically on the bottom plate as a tripod mounting screw. A tripod for a theodolite can be used in common with this surveying instrument. Moreover, this shared use does not impair the shifting function of the theodolite with a shift. In order to easily share a tripod, it is possible to prepare a centering rod as shown in Figure 3 a and b and configure it so that it can be attached to any of the centering rods of the tripod. It is cumbersome to carry two types, and the operation of changing the centering rod is necessary, which is why the invention of the present invention is superior.
