【考案の詳細な説明】
本案は金属製パイプシヤツターに関するもので
ある。[Detailed description of the invention] This invention relates to a metal pipe shutter.
この種の金属製シヤツターは、細い芯軸に口径
の大きい外筒を嵌合したものであり、芯軸と外筒
の間にガタツキを生じ、シヤツターの昇降時に不
快音を発生するものであつた。 This type of metal shutter consists of a thin core shaft fitted with a large diameter outer cylinder, which causes looseness between the core shaft and the outer cylinder, producing unpleasant noises when the shutter goes up and down. .
このような問題を解決する手段として、実開昭
57−89796号公報には芯軸と外筒の間にブツシユ
を介在したり、リンクの軸受部を円形状に突出し
て外筒を嵌合させた構造が開示されている。 As a means to solve such problems,
Japanese Patent No. 57-89796 discloses a structure in which a bush is interposed between the core shaft and the outer cylinder, or the bearing part of the link is protruded in a circular shape to fit the outer cylinder.
しかしながら、これらは外筒がブツシユあるい
はリンクの軸受部に幅広く接触しているため、接
触抵抗が大きく、不快な軋み音を伴つたり、負荷
が増して円滑な昇降操作ができなかつた。 However, in these systems, the outer cylinder makes wide contact with the bush or the bearing of the link, resulting in large contact resistance, unpleasant creaking noises, and increased load, making smooth lifting and lowering operations impossible.
本考案者等は、このような事情に鑑み鋭意検討

せることによつて、不快音を伴わず円滑に作動し
うる金属製パイプシヤツターを見い出した。 In view of these circumstances, the inventors of the present invention, as a result of intensive studies, inserted the parallel core shafts 1, 1... into the through holes at both ends of the links 2, 2... In a shutter in which outer cylinders 3, 3... are interposed on the core shaft, a plurality of chevron-shaped protrusions 4, 4... are provided on the inner peripheral surface of the outer cylinders 3, 3, or on the outer peripheral surface of the core shaft 1.
We have found a metal pipe shutter that can operate smoothly without unpleasant noise by forming the outer cylinders 3, 3, . . . and the core shaft 1 in linear contact with each other.
本案の実施に適する山形突条４，４…を備えた
芯軸１，１…あるいは外筒３，３は、アルミニウ
ム成型加工によつて量産することができる。 The core shafts 1, 1... or the outer cylinders 3, 3 equipped with the chevron-shaped protrusions 4, 4, etc. suitable for carrying out the present invention can be mass-produced by aluminum molding.
本案は上記の如き構成であり、外筒３，３…の

む外観を与えることができる。 The present invention has the above configuration, and a plurality of chevron-shaped protrusions 4, 4... are formed on the inner circumferential surface of the outer cylinders 3, 3... or the outer circumferential surface of the core shaft 1, and the outer cylinders 3, 3... and the core shaft 1 linearly abut against the core shafts 1, 1... and the outer cylinders 3, 3...
Since the runout of the core shaft 1 and the outer cylinders 3 and 3 are restricted,
The contact resistance of... can be significantly reduced, allowing smooth operation during lifting and lowering, and there is no unpleasant noise caused by rattling of the outer cylinders 3, 3..., and the outer cylinders 3, 3... are thin-walled. It is possible to give a dignified appearance with a small amount of material.
