Claims

[Scope of utility model registration request]

(1) The tension rod, which constantly tensions the step chain by pulling the movable driven wheel with spring force, positions and fixes the push plate for operating the switch, and
The device is equipped with a limit switch that is activated by movement of the push plate by a predetermined stroke and detects elongation of the step chain beyond the permissible limit, and a fixing piece that can position and fix the push plate with respect to the tension rod; A four-step elongation detection device for an unconveyor, characterized in that it is composed of two parts: a switch operation part that can be fixed at a fixed point with respect to a part and can be slid in a direction parallel to a tension rod.

(2) The fixed part and the switch operation part have a round hole for bolt insertion on one side, and an elongated hole for sliding and a semi-round hole for fixed point positioning recessed from the side edge of the elongated hole on the other side. A step chain elongation detecting device for a passenger conveyor according to claim 1, characterized in that the step chain elongation detecting device is connected to each other by bolting.

(3) The step chain elongation detecting device for a passenger conveyor according to claim 1 or 2, wherein the switch operation piece has a handle for sliding operation.
