[0054] 11 to 14 show an access safety device according to a second embodiment of the present invention.

[0055] The entrance safety device 20 according to the second embodiment includes: an entrance part 21 , an entrance support part 22 , a fixing part 23 , two pairs of connection parts 24 , a pulling spring 25 and a safety switch 26 . The inlet member 21 fits in the rail / handrail hole 7 on the front panel 6c with only its top end protruding (approximately 5mm) from the protrusion 6d on the front panel 6c. The inlet support member 22 is fixed to the rear end portion of the inlet member 21 . The fixing member 23 is fixed to the escalator main body (conveyor main body). The connection members 24 are configured as inlet movement guides for connecting the inlet support members 22 to the fixed members 23, respectively. The tension spring 25 serves as biasing means for biasing the inlet part 21 in a direction opposite to the moving direction h of the moving armrest 5 . The safet...

Abstract

An entrance safety device for a passenger conveyor includes: an entrance part covering the outer periphery of a moving handrail at a position where the moving handrail enters a skirt, and is movably arranged along a moving direction of the moving handrail; an entrance support fixed to the entrance part Parts; a fixed part fixed to the escalator main body; two leaf springs provided between the entrance support part and the fixed part and arranged substantially parallel to each other; and for detecting displacement of the entrance part along the moving direction of the moving handrail safety switch. Two plate springs guide the movement of the inlet member from the moving direction of the moving armrest to a direction narrowing the gap between the outer surface of the moving armrest and the inner surface of the inlet member, the inner surface being opposite to the outer surface of the moving armrest.
