Description
【考案の詳細な説明】 本考案は磁針の放置に関するものである。[Detailed explanation of the idea] This invention relates to leaving a magnetic needle alone.
本考案の目的は、組立容易で９０°に限らず、角度が自
在にとれ、しかも無接触で支持できる新規な磁針を提供
することにある。The purpose of the present invention is to provide a new magnetic needle that is easy to assemble, can be set at any angle other than 90 degrees, and can be supported without contact.
前記の目的を充足するため本考案は周面にＮ。In order to satisfy the above object, the present invention has N on the circumferential surface.
Ｓ極が表われる円筒形親磁石１を竪軸２により支持体３

接して水平指針軸４に円盤形被動磁石５を固定し、水平
指針軸４は指針６を有し、かつ支持体３に回転可能に支
承したものである。A cylindrical parent magnet 1 with an S pole is supported by a vertical shaft 2.
A disk-shaped driven magnet 5 is fixed to a horizontal pointer shaft 4 in close proximity to the upper surface of the cylindrical parent magnet 1, and the horizontal pointer shaft 4 has a pointer 6, and a support member 3 It is rotatably supported.
尚第１図乃至第３図に示す実施例においては、円板状指
針６を周り振動による動揺を制止するため鉱油７を封入
した匣体３′内に親磁石１を枢支し、これを支持体３に
着脱可能に取付は匣体３′を支持体にしたものである。In the embodiment shown in FIGS. 1 to 3, the parent magnet 1 is pivotally supported in a case 3' containing mineral oil 7 in order to suppress vibrations caused by surrounding the disc-shaped pointer 6. The housing 3' is removably attached to the support 3.
図中８は匣体３′の底蓋９に施したバッキングを示す。Reference numeral 8 in the figure indicates the backing applied to the bottom cover 9 of the case 3'.
又第４図の実施例では竪軸２に親磁石１を取付けると共
にその上に円盤状補助磁石１０を固定してこれを水平指
針軸４の被動磁石５に近接させたものであるが、この補
助磁石は必ずしも用いることを要しない。In the embodiment shown in FIG. 4, a master magnet 1 is attached to the vertical shaft 2, and a disc-shaped auxiliary magnet 10 is fixed thereon, which is placed close to the driven magnet 5 of the horizontal pointer shaft 4. It is not necessary to use an auxiliary magnet.
尚又指針６は固定目盛板１１の周りに回動する針状のも
のを用いである。Furthermore, the pointer 6 is a needle-like object that rotates around a fixed scale plate 11.
１２は支持体３に設けた指針を被う透明板を示す。Reference numeral 12 indicates a transparent plate that covers the pointer provided on the support body 3.
本考案は以上の構成であるから、従来の指針のように歯
車を用いず、磁石と指針とは無接触であるためトルクの
損失がなく、正確円滑に作動し、組立操作も容易である
。Since the present invention has the above structure, it does not use gears unlike conventional pointers, and since there is no contact between the magnet and the pointer, there is no loss of torque, it operates accurately and smoothly, and is easy to assemble.
そして垂直面に指針が位置するので見易く角度も９０°
に限らず自在に回動する等の効果がある。And since the pointer is located on the vertical plane, it is easy to see and the angle is 90°.
It has the effect of being able to rotate freely, etc.
