Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object prevention device for a passenger conveyor that prevents clothing such as a coat or shoes from being caught in a gap between a step of a passenger conveyor such as an escalator or a moving sidewalk and a skirt guard.

  Conventionally, in passenger conveyors such as escalators and moving walkways, there is a gap of about 2 mm between the step and the skirt guard, and there is a possibility that clothes such as a coat or shoes may be caught in this gap. In the unlikely event that clothing such as a coat or shoes are caught, the user may fall.

  In addition, as a prior art, the both sides of the tread were perforated so as to penetrate the tread in the width direction, and a closing band in which the extending amount of the tread in the width direction from the both sides of the tread was extended and retracted A connecting rod that is inserted through the communication hole to connect the blocking band, and moves the blocking band integrally in the width direction of the tread, and a blocking that restricts the movement of the blocking band in the contraction direction so that the extension amount becomes the minimum set value. A gap closing device for a passenger conveyor having a band movement regulating means and a spring for biasing the closing band so that the extension amount becomes a reference set value is known (for example, see Patent Document 1).

JP 2006-199443 A

  In conventional passenger conveyor gap closing devices, the closing band that closes the gap is made up of a member such as a brush having flexibility, so when clothing such as a coat or shoes enters, it becomes a flexible member such as a brush. There is a high possibility of moving while being sandwiched, and it was not expected to be very effective when clothing such as a coat or shoes were caught in the gap.

  The present invention has been made to solve the above-described problems, and is provided with an anti-pinch object that constantly contacts the step with the skirt guard at a constant pressure to eliminate the gap between the step and the skirt guard. An object of the present invention is to provide an object prevention device for passenger conveyors that prevents clothing or shoes from being caught.

  In the object prevention device for passenger conveyors according to the present invention, in the passenger conveyor operated with a gap formed between the tread board and the skirt guard, it is provided so as to extend in the horizontal direction at both ends of the tread board, respectively. And an elastic body that is provided between the object pinching prevention body and the inner side surface of the tread board and constantly presses the object pinching prevention body against the skirt guard with a certain pressure.

  The object pinching prevention body includes a plurality of any of a rotating ball, a sliding body having a small friction coefficient, and a rotating roller in a horizontal direction at a portion in contact with the skirt guard.

  In addition, the anti-pinch object includes a plurality of individual casters in the horizontal direction at a portion in contact with the skirt guard.

  According to the present invention, the tip of the pinch prevention body is always pressed against the skirt guard side with a constant pressure so as to eliminate the gap between the tread board and the skirt guard by the elastic body. There is no gap between them, and there is no fear that clothes such as coats and shoes will fall into the gaps, and therefore it is possible to prevent accidents caused by clothes or shoes such as coats being caught in the gaps. is there.

Embodiment 1 FIG.
1 is a front view of a step showing a schematic configuration of a passenger conveyor object pinching prevention device according to Embodiment 1 of the present invention, FIG. 2 is a plan view of the step, and FIG. 3 is a passenger conveyor according to Embodiment 1 of the present invention. 4 is a partial cross-sectional view showing the configuration of the main part of the object pinching prevention apparatus, FIG. 4 is a perspective view showing the main part configuration of the object pinching prevention apparatus for the passenger conveyor according to Embodiment 1 of the present invention, and FIG. FIG. 6 is a cross-sectional view showing an example in which a sliding ball having a small friction coefficient is provided at the tip of the object pinch prevention body, and FIG. 7 is a tip of the object pinch prevention body. It is sectional drawing which shows the example provided with the rotation roller in the part.

  In the figure, 1 is a step of a passenger conveyor such as an escalator, 2 is a tread, 3 is a riser, 4 is a follower roller, and 5 is a connected type attached to both ends of the tread 2 so as to extend horizontally. It is an object to prevent pinching. In this connection-type pinch prevention body 5, a single tip 5a extending in the horizontal direction always has a gap between the tread 2 and a skirt guard (not shown) by two pressing springs 6 described later. It is pressed against the skirt guard with a constant pressure so that it disappears. Reference numeral 6 denotes an elastic body composed of two pressing springs and the like provided between the two base portions 5b separately provided at the rear portion of the connection-type object pinching prevention body 5 and the inner surface of the tread board 2. . The pressing spring 6 constantly presses the single tip 5a of the object pinching prevention body 5 evenly to the skirt guard side with a constant pressure so as to eliminate a gap between the tread board 2 and the skirt guard. A plurality of rotating balls 5c, a sliding body 5d having a small friction coefficient, a rotating roller 5e, and the like are provided in a row in the portion of the single object portion 5a that contacts the skirt guard. ing.

  According to the first embodiment, the single tip portion 5a of the pinch prevention body 5 is constantly pressed by a constant pressure so that the spring 6 eliminates the gap between the tread 2 and the skirt guard (not shown). Since it is pressed against the skirt guard, there is no gap between the tread board 2 and the skirt guard (not shown), and there is no fear that clothes such as coats and shoes fall into the gaps. Accidents caused by being caught in the gap can be prevented in advance.
