Abstract

PROBLEM TO BE SOLVED: To secure a railing device for a passenger conveyor, which detects the occurrence of deformation in an edge part at the conveyor belt side of a rail frame base. SOLUTION: This railing device is provided with a rail frame base 6 constituting the top face of rail 4 along the traveling direction of a conveyor belt, and a handrail 17 is installed in this rail frame base 6, guiding the travel of a traveling rail 18. Then, an abnormality detecting means 19 detecting the upward deformation of an edge part at the side of the belt conveyor of the rail frame base 6 is installed in a fixed part of the rail 4. With this, any deformation in an edge part of the rail frame base 6 is detected and a passenger conveyor in time of abnormality is controlled, whereby such a nonconformity as pinching fingers of a passenger, traveling by grasping the traveling rail 18, between the edge part of the rail frame base 6 and the traveling rail 18, attributable to the edge deformation of the frame base 6 is obviated.

[0024]

As described above, according to the present invention, a balustrade standing upright along the moving direction of the transporting band, a balustrade frame base constituting the upper surface of the balustrade, and a projecting projecting upward from the balustrade frame base. A handrail that is guided by the handrail rail and moves, and an abnormality detection unit that is provided inside the balustrade and detects deformation of the edge of the balustrade frame base on the side of the transport band.

As a result, the deformation of the edge of the balustrade frame base is detected. By controlling the passenger conveyor in an abnormal state through this detection, the moving handrail is grasped due to the edge deformation of the balustrade frame base. This has the effect of preventing the occurrence of problems such as the finger of the passenger moving at the position being pinched between the edge of the balustrade frame base and the moving handrail.

Further, as described above, the present invention is provided with an abnormality detecting means comprising a strip-shaped switch whose length is arranged along the length of the balustrade frame base.

As a result, the deformation of the edge of the balustrade frame base is detected, and the passenger conveyor is controlled in an abnormal state through this detection, whereby the moving handrail is grasped due to the deformation of the balustrade frame base edge. This has the effect of preventing the occurrence of problems such as the finger of the passenger moving at the position being pinched between the edge of the balustrade frame base and the moving handrail. In addition, since the abnormality detecting means including the belt-shaped switch is arranged along the length of the balustrade frame base, the deformation occurrence position of the edge of the balustrade frame base may be any position in the longitudinal direction of the balustrade frame base. It is reliably detected. Therefore, there is an effect that the problem caused by the deformation of the edge of the balustrade frame base is more effectively prevented.
