Only the drive chain 4, the first roller 6, and the rail 9 protrude from the projection plane of 0.

According to this embodiment, the space on both the left and right sides of the passenger conveyor can be reduced. However, if the space is reduced, maintenance and inspection work becomes difficult. Further, since the second roller 7 and the rail 10 are arranged deep inside the step, maintenance and inspection becomes more difficult. Therefore, in order to prevent deterioration of maintenance and inspection workability, the main step 1 and the sub step 2
The step connection portion 3 connecting the step connection side can be separated into a main step side connection portion and a sub step side connection portion.

FIG. 7 shows details of the step connection portion 3. The main step 1 and the sub step 2 have just reached the end of the upper horizontal portion and are about to be inverted. The element of the drive chain 4 to which the front shaft 5 is attached by the nut 6 is approaching the extreme ends of the pair of left and right upper sprockets 12 arranged at the ends of the upper horizontal portion. At this position, the main step side connecting portion and the sub step side connecting portion are separated for maintenance and inspection.

A connecting shaft 16 extending in the width direction is attached to the lower surface of the passenger riding surface member 20 of the main step 1 at the rear end portion thereof. Rotating brackets 17 are attached to both ends of the connecting shaft 16 so that the passenger mounting surface member 20 of the follower step 12 is rotatably attached to the connecting shaft 16. A fixed bracket 18 for positioning the passenger mounting surface member 20 of the follower step is attached to the lower surface of the front end of the follower step 12 together with the rotating bracket 17. The rotary bracket 17 and the fixed bracket 18 are fixed with bolts 19. When the front shaft 5 reaches the foremost end, the bolts 19 are loosened to remove the fastening between the rotary bracket 17 and the fixed bracket 18, and the main shaft side connecting portion having the connecting shaft 16 and the rotary bracket 17 and the fixed bracket 18 are removed. The follower-step-side connecting portion that it has is separated.

If the bolt 19 is removed while the main step 1 and the sub step 2 are bent, only the sub step 2 can be easily removed. Therefore, for each member that is difficult to perform maintenance and inspection inside the passenger conveyor, an opening is formed in the step for maintenance and inspection, and the drive chain 4 is circulated to move the opening. Easy maintenance and inspection. This improves workability for maintenance and inspection.

According to this embodiment, the step is divided into a main step and a sub step so as to be bendable, and a passenger riding surface is formed on both the main step and the sub step, and either one of the main step and the sub step is formed. Since the kicking surface is formed, both steps are integrated to form one step of the step-like inclined surface. As a result, the angle of the inclined surface becomes gentle and the depth dimension of the passenger loading surface that is about double the height of the same step can be obtained. Also, since the steps move in a circulating manner, the steps are inverted at the upper and lower ends, but since the main step and the sub steps are flexibly connected, the sprocket diameter does not increase and the required installation space for the upper and lower ends is increased. Can be suppressed. In the present embodiment, the drive chain 4 is attached to the main step 1 via the front shaft, but the same operation can be performed even if the sub step 2 is provided with a shaft and is engaged with the drive chain 4 via this shaft. Can be done.

[0027]

As described above, according to the present invention, in the connecting step type passenger conveyor, some of the rollers for driving the passenger conveyor are provided inside the area occupied by the passenger mounting surface member on which the passenger is placed. Since it is arranged, the width dimension of the passenger conveyor can be reduced. As a result, the installation space for the passenger conveyor can be reduced. Further, the follower steps connected to the main step can be easily removed at the time of maintenance and inspection, and the workability at the time of maintenance and inspection can be maintained and improved even if the width of the passenger conveyor is narrowed.
