Entrance safety device for passenger conveyer

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.

Description

technical field [0001] The invention relates to an entrance safety device of a passenger conveyor, which is used to prevent accidents that foreign objects are brought in at the position where a moving handrail enters a skirt. Background technique [0002] An escalator as a passenger conveyor includes: a truss structure arranged between an upper floor and a lower floor; a plurality of steps connected to each other to form an endless loop, the plurality of steps moving in a cyclic manner in the truss structure; A pair of railings set upright on the sides in the width direction of the steps; a pair of moving handrails that are continuously circulated, attached to the periphery of the railings, and move synchronously with the steps; a pair of skirts on the lower portion of the pair of railings. [0003] Each moving handrail emerges from its corresponding skirt at a passenger platform where passengers board the escalator and moves outwardly while moving along the top of the rail...

AI Technical Summary

Problems solved by technology

[0013] As mentioned above, the first to the third prior art cannot prevent passenger's fingers etc. In the gap between, the inner surface is opposite to the outer surfaces 102a, 112a and 122a

[0014] In addition, in the first to third prior arts, a plurality of sets of parts for detecting the movement of the inlet parts 103, 113 and 123 are provided at the skirts below the inlet parts 103, 113 and 123, respectively, and at the The lower part of the skirt takes up a lot of space

This makes it difficult to install information display devices such as monitors in the lower part of the skirt, because the information display devices etc. installed in this way will be hindered by the multiple components
