【考案の詳細な説明】 「産業上の利用分野」 本考案は、起倒する根元桿の先に水平の姿勢で昇降す
る単桿を連結支持して成る腕木を備えた腕木式遮断機に
関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an armor type circuit breaker equipped with arms that connect and support a single rod that moves up and down in a horizontal posture to the tip of a base rod that is tilted.
「従来の技術」 腕木式遮断機は、列車通過時等に横断路を一時閉鎖す
るのであるが、自動車が無理に渡ろうとしたとき踏切り
内にとじ込められてしまうことがある。事故を防止する
ためには、自動車は腕木が遮断しているにもかかわらず
無理に通過しなければならない。"Prior Art" The armor type circuit breaker temporarily closes the crossroads when passing a train, etc. However, when a vehicle tries to cross forcibly, it may be trapped inside a railroad crossing. In order to prevent accidents, the car must pass by force even though the arms are blocked.
このような場合の腕木の折損事故を防止するものとし
て特許第722054号として実施されている折損防止器があ
る。There is a breakage preventer implemented as Japanese Patent No. 722054 as a device for preventing a breakage accident of the arm in such a case.

れ曲がり不能に支持し、また、折れ曲がったときは元に
復帰するような弾撥部材も設けられている。That is, the breakage preventive device is interposed between the base portion of the arm and the tip side thereof, and supports the tip side so that the tip side can be rotated obliquely upward and lifted when the vehicle hits and advances. There is also provided an elastic member that always supports the tip end side with a predetermined holding force in a non-bendable manner and returns to its original position when it is bent.

げ、結局折損に至ることになり、有効な腕木の折損防止
対策がないという問題点があった。"Problems to be solved by the invention" However, such a conventional technique is effective when the arm is a single rod, but a single rod that moves up and down in a horizontal posture is provided at the tip of the base rod. So, if the root bar is equipped with a breakage preventer, if the car hits, the base bar will escape diagonally upward, but the single bar will hang down and prevent the car from passing, eventually leading to breakage There was a problem that there was no breakage prevention measure.

腕木式遮断機に存する。"Means for Solving the Problem" The gist of the present invention for achieving such an object is to include a stem (20) including a root rod (25) and a single rod (21),
In the armor type circuit breaker including the tension member (40) and the breakage preventive device (28), the base rod (25) is pivotally supported by the main shaft (32) at the base end of the circuit breaker body (30). The single rod (21) has an arm (22) that is pivotally supported at the tip of the base rod (25) via a support shaft (26) and extends from the base portion.
The tension member (40) is moved up and down in a horizontal posture, and the tension member (40) is composed of a shackle rod (41) on the side of the breaker body (30) and a tension cable (45). (3
4) and a connecting shaft (23) at the tip of the arm (22) of the single rod (21) that connects the tip of the tension cable (45), and the shackle rod (41) has a tension member (40). The tension cable (45) forms the base of the and the connecting shaft (34) between the tip of the shackle rod (41) and the tip of the arm (22).
It is stretched between both connecting shafts (34, 23) by connecting to each other, and the connecting shaft (34) at the base of the shackle rod (41) is displaced from the main shaft (32) of the root rod (25). Is provided at the base of the circuit breaker main body (30) so as to be rotatable only around a horizontal axis when tilted, and the connecting shaft (23) at the tip of the tension cable (45).
And the connecting shaft (23) at the base end of the shackle rod (41) of the tension member (40), the main pivot shaft (32) and the support shaft (26) at the tip of the base rod (25) are arranged so as to form a parallelogram. The breakage preventer (28) has a connecting shaft (28a) and is interposed in the base rod (25), and the connecting shaft (28a) connects the base of the shackle rod (41). The base of the base rod (25) is on the side of the breaker body (30) with respect to the shaft (34), and the base of the base rod (25) is connected to the shaft (28).
a) A wristwatch type circuit breaker characterized in that it is arranged at a position where it can be bent obliquely upward by pivoting around.
「作用」 常時は、根元桿を起伏駆動することにより横断路を一
時閉鎖し、あるいは開放する。"Operation" At any time, the traverse is temporarily closed or opened by driving the base rod up and down.
横断路を一時閉鎖しているとき、根元桿と先端間とが
水平に一直線になった腕木が横断路を遮断する。When the crossroads is temporarily closed, the arms that have a horizontal line between the base rod and the tip block the crossroads.

の通過路が形成される。When the tip side of the base rod is bent obliquely upward, the shackle rod on the base side of the tension member stands up so as to stand up around the horizontal connecting shaft, as in normal operation.
Since the tension cable bends from the tip of the shackle rod and pulls the tip of the arm of the base of the single rod, the single rod rises in a substantially horizontal posture without a drooping tip, forming a passageway for an automobile.
自動車が通過すると、重力および折損防止器の復帰弾
