Description

本発明は、携帯用に適した水準器に関するものである。 The present invention relates to a level suitable for portable use.

従来の水準器には、測定用気泡管を備えた器体に、この器体を貫通する引っ掛け孔を形成し、この引っ掛け孔に壁に打たれた釘などを挿入して壁面などに掛け下げできたり、引っ掛け孔に挿入した連結リングなどを利用して携帯用の提げ紐などを連結できるようにしたものがあった（例えば、特許文献１参照。）。 In the conventional level, a hook hole that penetrates the container is formed in the container equipped with a measuring bubble tube, and a nail or the like hit on the wall is inserted into the hook hole and hung on the wall or the like. In some cases, a portable strap or the like can be connected using a connecting ring inserted into a hooking hole (see, for example, Patent Document 1).

しかし、このような従来の水準器の引っ掛け孔は、器体を貫通する孔であるために、器体の厚み分の孔長があり、また器体端縁とこの引っ掛け孔とが離れている場合もあり、この孔長のある引っ掛け孔にはフックやカラビナなどの環出入口の小さい連結環を直接連結することができず、先端部に連結環を付した携帯用紐などの落下防止用線体などを使用したい場合には、前述のように例えばこのような引っ掛け孔に取り付けできる線材で構成された連結リングなどを引っ掛け孔に装着しておいて、この連結リングに対して先端部の連結環を連結する必要がある。 However, since the hook hole of such a conventional level is a hole penetrating the container body, there is a hole length corresponding to the thickness of the container body, and the edge of the container body and the hook hole are separated from each other. In some cases, it is not possible to directly connect a connecting ring with a small ring entrance such as a hook or a carabiner to the hook hole with a long hole, but a fall prevention line such as a portable string with a connecting ring at the tip. If you want to use a body or the like, attach a connecting ring made of a wire that can be attached to such a hooking hole to the hooking hole as described above, and connect the tip to this connecting ring. It is necessary to connect the rings.

即ち、携帯に際しては、先端部に連結環を備えた携帯用紐などを使用するのが便利であるが、この携帯用紐を使用するためには別途もう一部品（連結リングなど）を用意しなければならず、煩わしかった。 That is, when carrying, it is convenient to use a portable string with a connecting ring at the tip, but to use this portable string, prepare another part (such as a connecting ring) separately. It had to be annoying.

そこで、出願人は、このような現状に鑑み、携帯用紐の先端部の連結環を直接連結することができる掛杆を器体の端部に山状に突出状態に設けて、携帯用紐の先端部の連結環を直接掛杆に掛止できる実用性に優れた水準器を開発した（特許文献２）。 Therefore, in view of the current situation, the applicant has provided a hook that can be directly connected to the connecting ring at the tip of the portable string in a protruding state in a mountain shape at the end of the container, Has developed a practical level that can directly hook the connecting ring at the tip of the hook to the hook (Patent Document 2).

Therefore, with the one side collar pressed against the inner side of the connecting ring, it is possible to easily perform a twisting / removing operation for detachment by opening / closing the opening / closing section by the opening / closing section pressing collar when the opposite side collar is engaged / disengaged. In addition, since the hook is made of a metal rod, the level of the hook is excellent in strength and durability as described above.

また、請求項３記載の発明においては、この連結環用通孔部とは別に通孔部を器体に設けていることで、例えば作業者の身体に掛け下げたり、結んだり、連結した落下防止用線体の先端連結部をこの器体に連結して落下防止状態に設けると共に、更にこの通孔部とは別に例えば作業者の腰に設けた開閉部付きの連結環用通孔部に掛け下げる場合には（例えば高所作業時に更に安全性を高めるために不使用時にはこの腰の連結環に掛け下げる場合には）、前述のようにして掛杆を用いてワンタッチで着脱できることになり、このように通孔部と連結環用通孔部との二つの通孔部を有し、その内の連結環用通孔部は大きく突出若しくは幅広く突出した山状の掛杆により大きく形成し、この大きく形成した連結環用通孔部により前記腰の連結環に前述のような操作で着脱できるように構成したから、前述のように極めてスピーディーに着脱できる極めて優れた水準器となる。 In addition, in the invention according to claim 3, by providing the through hole part in the container separately from the through hole part for the connection ring, for example, it is hung, tied or connected to the operator's body. In addition to connecting the tip connecting part of the wire for prevention to the container body and providing it in a fall-prevented state, in addition to this through-hole part, for example, a connecting ring through-hole part with an opening / closing part provided on the waist of the operator When hanging (for example, when hung on this waist connecting ring when not in use for higher safety when working at a high place), it can be attached and detached with a hook as described above. Thus, there are two through-hole portions, that is, the through-hole portion and the connecting-ring through-hole portion, and the connecting-ring through-hole portion is formed with a large protruding or wide protruding mountain-shaped hook. This large connecting hole for the connecting ring Since configured so as to be detachable in such operations, the outstanding spirit level that can be detached very quickly as described above.

また、請求項５記載の発明においては、器体に測定用気泡管を挟持固定すると共に掛杆も固定できる一層優れた水準器となる。 Further, in the invention described in claim 5, it becomes a more excellent level that can hold and fix the measurement bubble tube to the vessel body and can also fix the hanging hook.
