The handrail 13 is composed of an endless rail member that is attached along the periphery of the balustrade 11 and rotates in the same direction as the step 12 in synchronization with the step 12 by a drive device housed within the deck cover 10.

[Passing floor]
The boarding/alighting floor 1 is a plate-like member installed on the floor surface of the boarding/alighting entrance to the step 12, and is made of a metal member. In addition, grooves 1b and protrusions 1a (see FIG. 4A) for anti-slip purposes are alternately provided on the surface of the boarding/alighting floor 1 that becomes the tread surface of the user. The grooves 1b are provided so as to extend in a direction perpendicular to the direction of movement of the user (one direction X), and are provided at a predetermined depth and interval. In the boarding/alighting floor 1, the surface of the protrusion 1a provided between the two grooves 1b, 1b becomes the walking surface of the user. If the direction of movement of the user is the other direction Y, the width of the grooves 1b in the other direction and the width of the protrusions 1a in the other direction are configured to have a width that exerts an anti-slip effect when the user walks.

In this embodiment, the boarding/alighting floor 1 is provided with a display unit 3 (a passenger conveyor display unit of the present invention) that displays numbers, symbols, letters (hereinafter all referred to as "letters") indicating the number of floors. This display unit 3 is attached by a passenger conveyor plate 8 (see FIG. 2) described below, and one display unit 3 is composed of multiple letter pieces 5a (see FIG. 2) attached to the bottom of the groove 1b.

2. Passenger conveyor plate Next, a description will be given of the passenger conveyor plate 8 used to configure the desired display unit 3 on the landing floor 1 of the passenger conveyor 20 of this embodiment. Fig. 2 is a schematic diagram of the passenger conveyor plate 8. The passenger conveyor plate 8 is a plate for forming the display unit 3 displayed on the landing floor 1 of the passenger conveyor 20. Fig. 3 is an enlarged view of a portion A of Fig. 2.

As shown in FIG. 2, the passenger conveyor plate 8 comprises a plate body 2 and a pair of frame portions 4, 4. The plate body 2 is composed of a rectangular plate 5 made of a plate-like member extending in one direction X. In the plate body 2, a plurality of rectangular plates 5 are arranged at predetermined intervals in another direction Y perpendicular to the one direction X. In this embodiment, the outer shape of the plate body 2 is configured to be rectangular.

At least one of the rectangular plates 5 constituting the plate body 2 has a character piece 5a, a support piece 5b, and a connecting portion 5c connecting the character piece 5a and the support piece 5b, as shown in FIG. 3. The rectangular plate 5 also has a cutout portion 6 that separates the character piece 5a and the support piece 5b while leaving the connecting portion 5c. The width of the rectangular plate 5 in the other direction is configured to be able to fit into the groove portion 1b provided in the boarding/alighting floor 1. In other words, the width of the rectangular plate 5 in the other direction is configured to be approximately the same as or smaller than the width of the groove portion 1b in the other direction. The width of the rectangular plate 5 in one direction and the number of rectangular plates 5 provided vary depending on the size of the display portion 3 formed on the boarding/alighting floor 1.

The character pieces 5a on the rectangular plate 5 are part of the display unit 3 and are cut into a predetermined shape by the cutouts 6. The cutouts 6 are cut into a predetermined shape to form the character pieces 5a. The cutouts 6 are also cut to separate the support pieces 5b and the character pieces 5a, leaving behind connecting parts 5c that have a width smaller than the width of the rectangular plate 5 in other directions. The connecting parts 5c are configured to be wide enough that the connection between the character pieces 5a and the support pieces 5b does not come loose when an operator grasps the frames 4, 4 and lifts the plate body 2, and are also wide enough that they can be easily cut using a dedicated tool or the like.

In the plate body 2, a number of character pieces 5a are provided on a number of rectangular plates 5 to form meaningful letters, numbers, or symbols. The support pieces 5b are parts for supporting the character pieces 5a on the frame parts 4, 4. At both ends of the rectangular plates 5 in one direction, the support pieces 5b are connected to the frame parts 4, 4, so that the plate body 2 is supported on the frame parts 4, 4 in an integrated state.

The thickness of the rectangular plate 5 in the vertical direction perpendicular to one direction and the other direction is configured to be thinner than the depth of the groove 1b provided in the entrance floor 1 (see FIG. 4C). As a result, the display unit 3 (letter piece 5a) installed on the entrance floor 1 does not protrude above the surface of the protruding portion 1a, so it does not interfere with the walking of users and is less susceptible to wear caused by users walking.

The pair of frame parts 4, 4 are provided at both ends in one direction of the plate main body part 2. The pair of frame parts 4, 4 are each configured to be connected to a rectangular plate 5 that constitutes the plate main body part 2. Each frame part 4, 4 extends in the other direction and is configured of a plate-like member that extends in a vertical direction perpendicular to the one direction and the other direction. The frame parts 4, 4 are configured by portions that are bent in the vertical direction from both ends in one direction of the plate main body part 2. The frame parts 4, 4 are the parts that a worker grasps when installing the display unit 3 on the boarding/alighting floor 1 using the passenger conveyor plate 8, and are configured to have a width that is easy for the worker to handle.

In addition, at the end of the frame 4, 4 connected to the support piece 5b, a clearance groove 4a (slit) is provided at a predetermined height in the vertical direction in the area between the two adjacent support pieces 5b, 5b. The vertical height of the clearance groove 4a is configured to be higher than the height of the convex portion 1a of the boarding/alighting floor 1 of the passenger conveyor to be installed (see FIG. 4B). This clearance groove 4a is a groove into which the convex portion 1a of the boarding/alighting floor 1 fits when each of the rectangular plates 5 of the plate main body 2 is fitted and installed on the boarding/alighting floor 1. By providing the clearance groove 4a, when the rectangular plate 5 of the plate main body 2 is installed on the bottom surface of the groove portion 1b of the boarding/alighting floor 1, the rectangular plate 5 can be fitted into the groove portion 1b. In addition, the operator can install the rectangular plate 5 of the plate main body 2 on the bottom surface of the groove portion 1b while holding the frame 4, 4.

The passenger conveyor plate 8 is made of a material with excellent abrasion resistance, and can be made of, for example, a metal material such as stainless steel, a plastic material with high hardness, or an elastic material. The plate body 2 and frame parts 4, 4 that make up the passenger conveyor plate 8 are integrally constructed, and can be formed, for example, by processing a single plate-shaped member. For example, a single plate-shaped member is punched out so that multiple rectangular plates 5 are provided, and a cutout part 6 is provided in each rectangular plate 5 so that a predetermined display part 3 is formed. Then, both ends in one direction of the plate body 2 are folded to form the frame parts 4, 4. This allows the passenger conveyor plate of this embodiment to be formed.

The manufacturing method for the passenger conveyor plate 8 is not limited to the above-mentioned example, and various other manufacturing methods can be applied, such as forming the rectangular plate 5, the cutout portion 6, and the frame portion 4 all at once by injection molding, etc.

3. Method of Mounting the Display Unit Next, a method of mounting the display unit 3 on the boarding/alighting floor 1 in this embodiment will be described. Figures 4A to 4C are diagrams (part 1) showing the mounting process of the display unit 3 in this embodiment. Also, Figures 5A and 5C are diagrams (part 2) showing the mounting process of the display unit 3 in this embodiment.

First, although not shown in the figure, an adhesive portion is formed on the side of the display portion 3 of the passenger conveyor plate 8 that is to be installed on the boarding/alighting floor 1 (the side opposite to the side on which the frame portions 4, 4 are provided). The adhesive portion is formed at least only on the letter pieces 5a of the rectangular plate 5. The adhesive portion can be formed using, for example, an adhesive or double-sided tape.

Next, as shown in Figures 4A and 5B, the side of the passenger conveyor plate 8 from which the frame parts 4, 4 protrude is positioned as the upper surface, and the plate is aligned at a predetermined position on the entrance/exit floor 1. Here, while holding the frame parts 4, 4 of the passenger conveyor plate 8, the worker aligns the display part 3 of the passenger conveyor plate 8 so that it is located at the intended position of the display part 3 on the entrance/exit floor 1.

Next, as shown in FIG. 4B, the passenger conveyor plate 8 is lowered toward the entrance floor 1 while being aligned, and the rectangular plate 5 is inserted into the groove 1b and adhered to the bottom surface of the groove 1b. In this embodiment, the escape groove 4a provided in the frame parts 4, 4 is configured to be larger than the height of the protrusion 1a of the entrance floor 1. Therefore, the plate main body part 2 can be pressed against the bottom surface of the groove 1b of the entrance floor 1 via the adhesive part. In this state, the plate main body part 2 is pressed with the jig 100 to adhere the display part 3 to the bottom surface of the groove 1b of the entrance floor 1, and the connecting part 5c (see FIG. 3) is cut while pressing the jig 100, and the character piece 5a is separated from the support piece 5b.

Then, as shown in Figures 4C and 5B, the frames 4, 4 are grasped, and the passenger conveyor plate 8 from which the display unit 3 has been separated is lifted and removed from the entrance floor 1. This allows the support pieces 5b connected to the frames 4, 4 of the passenger conveyor plate 8 to be removed, with the display unit 3 remaining on the entrance floor 1. Here, depending on the shape of the display unit 3, the support pieces 5b other than the display unit 3 may remain on the entrance floor 1 side due to the cutting of the connecting parts 5c. In this case, the support pieces 5b remaining on the entrance floor 1 side are removed by a worker.

In this embodiment, the above process allows the desired display unit 3 to be formed in the groove 1b of the boarding/alighting floor 1. The display unit 3 attached using the passenger conveyor plate 8 of this embodiment is attached to the bottom surface of the groove 1b of the boarding/alighting floor 1. This allows the display unit 3 to be provided below the walking surface of the boarding/alighting floor 1, thereby avoiding problems such as peeling off due to friction from pedestrians. In addition, in the passenger conveyor plate 8 of this embodiment, the display unit 3 consisting of multiple character pieces 5a is integrally provided to the frame parts 4, 4 via the connecting parts 5c and the support pieces 5b. Therefore, handling is possible while maintaining the shape of the display unit 3, and the attachment work can be performed efficiently, improving workability.

Furthermore, in this embodiment, when installing the display unit 3, there is no need to perform work such as scraping the installation surface of the boarding/alighting floor 1. This improves work efficiency.

The above-mentioned embodiment has been described in detail to clearly explain the present invention, and is not necessarily limited to having all of the configurations described. For example, it is possible to replace part of the configuration of the embodiment with another configuration, and it is also possible to add another configuration to the configuration of the embodiment. It is also possible to add, delete, or replace part of the configuration of the embodiment with another configuration.
