Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly to a safety device for preventing an accident between a side of a step and a balustrade. 2. Description of the Related Art Conventionally, as a safety device for preventing an accident at the side of a step of a passenger conveyor, Japanese Patent Publication No. 55-18 / 78 is known.
As disclosed in Japanese Patent Publication No. 235/235, there is known a safety device that protrudes from a skirt guard near an entrance / exit so as to wrap around a side end of a step. The safety device prevents a person from being caught between the step and the skirt guard and a foreign object (such as a commuter pass) from entering the gap. [0003] The prior art described above has no specific reference to the mounting strength of the safety device or the maintenance workability, and has a problem that it needs to be improved in terms of maintaining safety and dealing with time. Was. An object of the present invention is to provide a safety device for a passenger conveyor which is excellent in mounting strength and maintainability of a safety device on a step side portion. [0005] In order to achieve the above object, the present invention has an endlessly connected and moving step;
In a passenger conveyor having a balustrade arranged upright on both sides of this step and a skirt guard, an inner deck cover, a balustrade panel and the like constituting the balustrade, the width dimension of the step is reduced on a vertical surface of the skirt guard. A safety device comprising a base member provided with a projecting portion projecting in the direction and easily fixed to the projecting portion, and a brush body planted on the base member and extending in a direction to reduce the width dimension of the step. Is provided. In the above construction, since the base body detachably fixed to the protrusion integrally formed with the skirt guard is directly attached, the strength of the attachment is high and the brush body constituting the safety device is deteriorated with time. This has the advantage that the maintenance work (replacement of the safety device) is extremely easy. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a passenger conveyor safety device according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a main part of a passenger conveyor and its safety device according to the present invention, and FIG. 2 is a sectional view taken along line MM in FIG.
In the figure, an escalator-type passenger conveyor 1 is installed from a lower floor 2 to an upper floor (not shown), and an entrance 3
Step 4 which is connected endlessly from the door to another entrance (not shown), moves, a balustrade 5 arranged upright on both sides of the step 4, a skirt guard 6 constituting the balustrade 5, an inner deck cover 7, balustrade panel 8, handrail 9 and the like. The vertical surface of the skirt guard 6 is provided with a protruding portion 6A that is bent integrally with the skirt guard 6 and protrudes by a length T (about 10 to 30 mm) in a direction to reduce the width dimension of the step 4. A base body 10A fixed with screws 11 on the protruding portion 6A,
A brush body 10B which is planted at A and closes a gap G between the step 4 and the skirt guard 6 and further extends by a length L (about 20 to 50 mm) in a direction in which the width dimension of the step 4 is reduced.
The safety device 10 composed of the above two is disposed over the entire travel path of step 4. In this case, the projecting portion 6A is integrated with the skirt guard 6 and has a structure in which the base body 10A is fixed to a position where the strength is increased (also becomes reinforcing) by the presence of the projecting portion 6A itself. It has strength enough to withstand even if a passenger puts his feet on the car or collides with baggage. In addition, the safety device 10 itself is engaged with a U-shaped groove covering the entire surface of the protrusion 6A.
The safety device 10 has a high fixing strength, and the safety device 10 is attached to and detached from the skirt guard 6 by the screw 11.
Can be easily dealt with by attaching and detaching the brush body 10B, thereby maintaining the brush body 10B in the case of deterioration with time such as wear and deformation (the safety device 1).
This is also advantageous in the operation of replacing 0). As described above, according to the embodiment of the present invention, it is of course possible to prevent a personal injury or a foreign object intrusion between the step 4 and the skirt guard 6, which is an original purpose of the safety device, more reliably by the protrusion length L than before. Thus, the safety device 10 can be improved in both fixing strength and maintainability. The mounting structure of the safety device 10 can be applied to a moving sidewalk as it is. To further increase safety, the safety device 10 is colored yellow, for example, to visually access the gap G. It is also possible to add measures to prevent this. As described above, according to the present invention, it is possible to obtain a passenger conveyor safety device which is excellent in mounting strength and maintainability of the step side safety device.
