The construction of this profile is easy to manufacture and facilitates assembly.
本発明によればこの課題は次の様にして解決しうるもの
である。According to the present invention, this problem can be solved as follows.

弛めた後もプロフィル・ケーシングの画部分か内嵌まり
合って互に結合し合っているように構成されていること
によって＃決しうるものである。i.e. independent of the means for tightening the two-part profile casing or the means for fixing the profile casing on one of said parts; and 2.
The sections of the profile casing consisting of two parts are provided with interfitting protrusions and recesses, so that even after loosening the means for tightening the profile casing, the force exerted on the profile casing remains This can be determined by the fact that they are constructed so that they fit inside each other and are connected to each other.
本発明の長所とするところは、特に、プロフィル・ケー
シングを作るのに２つの部分を簡単な連続鋳造用鋳型で
作ることができる点にある。An advantage of the invention lies, inter alia, in that two parts can be produced in a simple continuous casting mold to produce the profile casing.
測定具現装置をケーシングの１つの部分に俄りっけるこ
とは、従来の片側だけ開いた中空プロフィルの場合より
もかなり簡単であり、従来の中空プロフィルでは内部で
操作できる空間が少ない。Mounting the measurement implementation device in one part of the casing is considerably easier than in the case of conventional hollow profiles that are open on one side, in which case there is less space for maneuvering inside.
他の部分の取りつけも簡単に行われる。Attaching other parts is also easy.
しかも、測定装置が機械に摩りつけられたままでよいの
で、該装置全体の手入れもずっと簡単になる。Moreover, since the measuring device can remain attached to the machine, the overall maintenance of the device is much easier.
機械を作業する者は単に２つの部分よりなる中空プロフ
ィルの締め付けねじを完全に弛めさえすれは良く、それ

用するバネの張力にも拘らず相変わらず形状拘束的に互
に結合したままとなっており、中空プロフィルの上方部
分を嵌合的結合から外すために両方の千力咄由に使える
ことになる。The operator of the machine simply has to completely loosen the clamping screw of the two-part hollow profile, and the two-part hollow profile will still retain its shape despite the tension of the springs acting in opposite directions. They remain restrainedly connected to each other and can be used in both directions to release the upper part of the hollow profile from the mating connection.
分離個所にある２つの部分よりなる中空プロフィルを密
閉するために紐状パツキンか設けられている。A string-like seal is provided to seal the two-part hollow profile at the separation point.
さらに上記の長所から導かれるように、本発明の進歩し
た点は、製作、組立、手入れなしクリーニングか簡単で
あるため製作費保守費用が少くてよい点にある。Further, as a result of the above advantages, an advantage of the present invention is that it is simple to manufacture, assemble, and clean without requiring maintenance costs.
その上、組立は中空プロフィルの片側の開口から行われ
るのではなく、この理由から開口のための広さは不要で
あり、したかってケーシングの寸法を小さくすることも
できる。Furthermore, the assembly is not carried out through an opening on one side of the hollow profile, and for this reason no space is required for the opening and the dimensions of the casing can therefore also be reduced.
