Description

The present invention relates to a passenger conveyor that transports passengers using a circularly driven endless transport body.

Passenger conveyors such as escalators and moving walkways have a conveying section and a boarding/alighting entrance. The conveying section has an endless conveying body that moves along a passage to convey passengers. The boarding/alighting entrances have floor plates and are provided at the beginning and end of the passage (boarding entrance and exit entrance). Passengers enter the passage from the boarding floor plate, and when they move to the passenger receiving section of the endless conveying body, they are conveyed by the endless conveying body, and then when they reach the passenger sending-out section of the endless conveying body, they move to the exit floor plate and continue moving to leave the passenger conveyor.

When visually impaired people use passenger conveyors, it is necessary to consider not only safety but also how they can use the conveyor without stress. Guided entrances to the entrances by forming braille blocks on the floor or issuing audio guidance are already widely implemented measures. However, when two or more passenger conveyors are installed side by side and multiple entrances are lined up, visually impaired people may mistakenly go to the exits. Even if they reach the entrances, they do not know whether the passenger conveyor is going up or down. They can tell whether it is an entrance or an exit by touching the handrail or stepping into the passenger acceptance part of the endless conveyor. However, if it is an exit, the handrail or the endless conveyor is moving toward them, which is dangerous for visually impaired people. Also, they cannot tell whether it is going up or down until they get on the passenger conveyor. If the destination is incorrect, they will have to move unnecessarily by getting on another passenger conveyor and returning, which places a heavy burden on the visually impaired people.

To solve these problems, floor plates with various display functions have been proposed. The floor plate described in Patent Document 1 makes it possible to distinguish between the entrance and exit by changing the inclination direction of the steps. The floor plate described in Patent Document 2 provides multiple protrusions in an isosceles triangular area facing forward, and guides the user in the direction to proceed by placing the sole of the foot along the hypotenuse. The floor plate described in Patent Document 3 makes it possible to distinguish between going up and down by changing the braille pattern for going up and down.

However, the floor plate described in Patent Document 1 has the risk of causing visually impaired people to trip over steps. The floor plate described in Patent Document 2 has the problem that it is not necessarily easy for visually impaired people to identify the position of the hypotenuse, so the guiding effect may not be expected. The floor plate described in Patent Document 3 has the problem that it is not necessarily easy for visually impaired people to identify the position of the entire Braille pattern, so it may be difficult for them to understand the meaning of the Braille.

The first invention aims to provide a passenger conveyor that can easily distinguish between boarding and disembarking. The second invention aims to provide a passenger conveyor that can easily distinguish between going up and down.

The passenger conveyor according to the first invention comprises:
a conveying section that conveys passengers by an endless conveying body that is driven in a circular manner;
A boarding entrance and an alighting entrance for the conveying section are provided,
a floor plate constituting a floor of the entrance includes a display section in which a plurality of protrusions, each having a first shape that is longer in a front-to-rear direction than in a left-to-right direction of the entrance, are arranged at intervals from each other;
The floor plate constituting the floor of the exit is a passenger conveyor having a display unit in which a plurality of protrusions, each having a second shape that is longer in the left-right direction than in the front-to-back direction of the exit, are arranged at intervals from each other.

Here, as one aspect of the passenger conveyor according to the first invention,
The floor plate is
The body plate,
A display plate having a plurality of protrusions, each of which has a shape that is long in one direction, arranged at intervals from each other, which can be attached and detached from the main plate, and which can be attached to the main plate by selecting one of two orientations with an angle difference of 90 degrees, thereby selectively configuring either a first shape or a second shape of the protrusions.

The passenger conveyor according to the second invention comprises:
A conveying section that conveys passengers to upper or lower floors by an endless conveying body that is driven in a circular manner;
A boarding entrance and an alighting entrance for the conveying section are provided,
The floor plate constituting the floor of the entrance is provided with a display section in which a plurality of protrusions each having a first shape that is longer in the front-to-back direction than in the left-to-right direction of the entrance are arranged at intervals when the passenger conveyor is in the upward direction , and a plurality of protrusions each having a second shape that is longer in the front-to-back direction than in the left-to-right direction of the entrance and that gives a feeling to the sole of the foot when stepped on that is different from the first shape are arranged at intervals when the passenger conveyor is in the downward direction.

Here, as one aspect of the passenger conveyor according to the second invention,
The first shape of the protrusion is a shape in which either or both of the width and the height increase toward the endless conveyor,
The second shape of the convex portion is a shape in which either or both of the width and the height become smaller toward the endless conveyor,
The floor plate constituting the floor of the exit can be configured as follows: when there is an entrance for another passenger conveyor lined up to the right, the floor plate has a display section in which a plurality of protrusions are arranged at intervals from each other, each of which has a third shape in which the width or height, or both, of the protrusions decrease toward the entrance to the right, and when there is an entrance for another passenger conveyor lined up to the left, the floor plate has a display section in which a plurality of protrusions are arranged at intervals from each other, each of which has a fourth shape in which the width or height, or both, of the protrusions decrease toward the entrance to the left ...

Also, in this case,
The floor plate is
The body plate,
A display plate having a plurality of protrusions arranged at intervals from one another, each of which is long in one direction and has a shape in which either or both of the width and height decrease from one end to the other, the display plate being detachable from the main plate and being attached to the main plate in one of four directions with an angle difference of 90 degrees, thereby selectively configuring the protrusions to have one of the first shape to the fourth shape.

In addition, as another aspect of the passenger conveyor according to the first and second inventions,
The display plate has a square shape;
The main plate may have a stepped recess capable of accommodating one or more display plates.
Also, in this case,
The display plate has four screw insertion holes at point-symmetric positions around the center of the display plate,
The main plate has a screw hole at a corresponding location of the stepped recess,
The display plate is attached to the stepped recess by a screw.
The above configuration can be adopted.

According to the first invention, when the convex portion of the display unit has a first shape, the visually impaired person feels a small sense of resistance in the soles of their feet. This allows the visually impaired person to recognize from experience that it is OK to proceed, and understand that this is the entrance to the train. On the other hand, when the convex portion of the display unit has a second shape, the visually impaired person feels a large sense of resistance in the soles of their feet. This allows the visually impaired person to recognize from experience that it is not OK to proceed, and understand that this is the entrance to the train. Therefore, according to the first invention, it is easy to distinguish whether the train is at the entrance to the train or the exit to the train.

According to the second invention, the visually impaired person feels less resistance in the soles of their feet whether the convex portion of the display unit is the first shape or the second shape. In addition, the visually impaired person feels different sensations in the soles of their feet when the convex portion of the display unit is the first shape and when the convex portion of the display unit is the second shape. Here, it is assumed that the visually impaired person understands in advance that the first shape is a display form corresponding to the upward passenger conveyor and the second shape is a display form corresponding to the downward passenger conveyor. Alternatively, it is assumed that the first shape is a shape that gives the visually impaired person, for example, a sense of upward facing, and the second shape is a shape that gives the visually impaired person, for example, a sense of downward facing. In this case, when the convex portion of the display unit is the first shape, the visually impaired person understands that this is the entrance to the upward passenger conveyor. On the other hand, when the convex portion of the display unit is the second shape, the visually impaired person understands that this is the entrance to the downward passenger conveyor. Therefore, according to the second invention, it is easy to distinguish whether it is the upward or downward direction.

Below, an escalator, which is one type of passenger conveyor, will be described as one embodiment of the present invention with reference to Figures 1 to 7.

As shown in FIG. 1, the escalator 1 includes a truss (not shown), a conveying section 2, a handrail section 3, and a boarding/alighting entrance 4. The truss is a structure that supports the weight of the escalator 1 and the load of the load. The conveying section 2 is supported by the truss, and the tread moves along the passage, conveying passengers while standing in that position without making them walk. The handrail section 3 is also supported by the truss, and is provided on the left and right sides of the passage along the passage. The boarding/alighting entrance 4 is provided at the top of both ends of the truss. In this embodiment, the escalator 1 is set to convey passengers from the front to the back (from the lower floor to the upper floor). For this reason, the escalator 1 includes a boarding entrance 4A, a conveying section 2, and an alighting entrance 4B from the front to the back. When the setting is switched in the opposite direction, the boarding entrance 4A becomes an alighting entrance and the alighting entrance 4B becomes a boarding entrance, and the setting is set to convey passengers from the back to the front (from the upper floor to the lower floor).

The truss is a framework structure that appropriately combines upper chords, lower chords, vertical members, diagonal members, and cross beams. The truss has two horizontal ends and an inclined portion. One horizontal end is hung on a support frame on an upper floor of the building, and the other horizontal end is hung on a support frame on a lower floor. In this way, the truss, and thus the escalator 1, is installed in the building.

The conveying section 2 comprises an endless conveying body 20. The endless conveying body 20 is comprised of a number of steps 21, ... connected in an endless manner, and is driven in a circular motion. The handrail section 3 comprises a handrail 30 and a balustrade panel 31. The handrail 30, also known as a moving handrail, is flexible and endless, and is driven in a circular motion in conjunction with the endless conveying body 20. The balustrade panel 31 has its lower edge supported by a truss, and supports the handrail 30 so that it can be circulated.

The boarding/alighting entrance 4 is provided at the top of the horizontal end of the truss. The boarding/alighting entrance 4 has a floor plate 40. The floor plate 40 forms the floor of the boarding/alighting entrance 4 and forms the ends (starting end and ending end) of the passage. The front end of the floor plate 40 defines the boundary between the boarding/alighting entrance 4 and the transport section 2.

The floor plate 40 comprises a first plate 41 and a second plate 45. The first plate 41 is large enough to occupy the majority of the floor plate 40. The second plate 45 is also called a comb plate, and is arranged so that its rear end is butted against the front end of the first plate 41. The first plate 41 and the second plate 45 are metal plates made of, for example, iron, stainless steel, or aluminum.

The first plate 41 is placed on the horizontal end of the truss, can be easily removed, and is provided so that the inside of the horizontal end of the truss can be opened and closed. When the first plate 41 is removed, the folded end of the endless conveyor 20 placed inside the horizontal end of the truss becomes accessible.

The first plate 41 is divided into an appropriate number of pieces in the front-to-rear direction. In other words, the first plate 41 is a strip-like plate that is long in the left-to-right direction, and a single wide plate is formed by arranging multiple first plates 41, ... side-by-side in the front-to-rear direction. In this embodiment, two first plates 41, 41 are used.

The second plate 45 is a strip-like plate that is long in the left-right direction. The second plate 45 is attached to the horizontal end of the truss and fixed so that it cannot be easily removed. The upper surface of the second plate 45 has a gentle downward slope from the rear end to the front end. A comb-tooth-shaped comb 46 is attached to the front end of the second plate 45. The comb 46 is divided into multiple parts in the left-right direction, each of which has a rectangular shape (rectangular shape). The multiple combs 46, ... are arranged side by side in the left-right direction to form a strip-like shape that is long in the left-right direction along the front end of the second plate 45.

As shown in FIG. 2, the first plate 41 comprises a main plate 42 and multiple (two in this embodiment) display plates 43, ... The main plate 42 forms the main body of the first plate 41 and is a strip-like plate that is long in the left-right direction, with both ends placed on the horizontal ends of the truss. The display plate 43 is detachably attached to the area of the main plate 42 excluding both ends.

The main body plate 42 has a stepped recess 42a. The stepped recess 42a is formed across the front and rear ends of the main body plate 42, and has a horizontally long rectangular shape with a left-right width equal to (the front-rear width of the main body plate 42 x the number of display plates 43). The display plates 43 have a square shape with the length of one side equal to the front-rear width of the main body plate 42. In other words, the stepped recess 42a can accommodate multiple display plates 43 (two in this embodiment) side-by-side.

The display plate 43 is attached to the stepped recess 42a by a flat head screw 44, and can be removed by releasing the fastening of the flat head screw 44. A flat head screw is a screw with a flat head and a conical seat. A conical screw insertion hole is formed in the display plate 43 corresponding to the seat of the flat head screw 44. The screw insertion hole is formed at a point-symmetrical position (in this embodiment, the four corner positions of the display plate 43) centered on the center of the display plate 43. A screw hole is formed at the corresponding position of the stepped recess 42a. As a result, the display plate 43 can be attached to the main plate 42 (the stepped recess 42a) by selecting one of four orientations with an angle difference of 90 degrees.

Like the main plate 42, the display plate 43 is a metal plate made of, for example, iron, stainless steel, or aluminum. Alternatively, the display plate 43 may be a hard resin or rubber plate.

There are two types of display plates 43: a first display plate 43A shown in FIG. 3 and a second display plate 43B shown in FIG. 4. As described above, both have a square shape and have a first side 43a, a second side 43b, a third side 43c, and a fourth side 43d.

As shown in FIG. 3, the first display plate 43A has a plurality of protrusions 430, ... on the upper surface. The plurality of protrusions 430, ... are arranged at intervals from one another and are formed integrally with the first display plate 43A. The protrusions 430 are long in one direction (in this embodiment, the direction along the first side 43a and the third side 43c) when viewed from the front, and have a shape in which either or both of the width and height (in this embodiment, both) become smaller from one end side to the other end side (in this embodiment, an isosceles triangle shape when viewed from above).

The protrusion 430 has an upper surface 430a, left and right side surfaces 430b, 430b, and a rear end surface 430c. The inclination angle α of the upper surface 430a with respect to the horizontal plane is 1 degree or more and 7 degrees or less. The inclination angle β of the side surface 430b with respect to the above-mentioned one direction is 2 degrees or more and 11 degrees or less. The height h of the protrusion 430 is 5 mm or more.

As shown in FIG. 4, the second display plate 43B also has a number of protrusions 430, ... on its upper surface. The multiple protrusions 430, ... are arranged at intervals from one another and are formed integrally with the second display plate 43B. The protrusions 430 are long in one direction (in this embodiment, the direction along the first side 43a and the third side 43c) when viewed from the front and have a shape with a constant width and height (in this embodiment, a rectangular shape when viewed from above).

The protrusion 430 has an upper surface 430a, left and right side surfaces 430b, 430b, and front and rear end surfaces 430d, 430d. The inclination angle of the upper surface 430a with respect to the horizontal plane is substantially 0 degrees. The inclination angle of the side surface 430b with respect to the above-mentioned one direction is also substantially 0 degrees. The height h of the protrusion 430 is 5 mm or more, similar to the height h of the protrusion 430 of the first display plate 43A.

In order to improve visibility from a distance, the surfaces of the convex portions 430 of the first display plate 43A and the second display plate 43B may be colored, or the flat areas other than the convex portions 430 may be colored.

The escalator 1 according to this embodiment has the above configuration. Next, we will explain a display example using the display plate 43 in a configuration in which two escalators 1, 1 are installed side by side and two boarding and alighting entrances 4, 4 are arranged side by side.

In the display example 1 shown in FIG. 5(a), both the left escalator 1A and the right escalator 1B are downward, and the entrance 4A of the left escalator 1A and the exit 4B of the right escalator 1B are arranged side by side. i) At the entrance 4A of the left escalator 1A, a plurality of first display plates 43A, ... (in this embodiment, two plates for each of the two first plates 41, 41, a total of four plates) are used with the convex portion 430 oriented vertically and with the width and height of the convex portion 430 decreasing toward the endless conveyor 20, that is, with the tip of the convex portion 430 facing the endless conveyor 20 (corresponding to the first shape in claim 1 and the second shape in claim 3). ii) At the exit 4B of the right escalator 1B, a plurality of second display plates 43B, ... are used with the convex portion 430 oriented horizontally (corresponding to the second shape in claim 1).

In display example 2 shown in FIG. 5(b), both the left escalator 1A and the right escalator 1B are upward, and the exit 4B of the left escalator 1A and the entrance 4A of the right escalator 1B are side-by-side. i) At the exit 4B of the left escalator 1A, multiple second display plates 43B, ... are used with the convex parts 430 oriented horizontally (corresponding to the second shape of claim 1). ii) At the entrance 4A of the right escalator 1B, multiple second display plates 43B, ... are used with the convex parts 430 oriented vertically (corresponding to the first shape of claim 1 and the first shape of claim 3).

In the display example 3 shown in FIG. 6(a), the left escalator 1A is for descending and the right escalator 1B is for ascending, and the entrance 4A of the left escalator 1A and the entrance 4A of the right escalator 1B are arranged side by side. i) At the entrance 4A of the left escalator 1A, a plurality of first display plates 43A, ... are used with the convex portion 430 oriented vertically and with the width and height of the convex portion 430 decreasing toward the endless conveyor 20, i.e., with the tip of the convex portion 430 facing the endless conveyor 20 (corresponding to the first shape in claim 1 and the second shape in claim 3). ii) At the entrance 4A of the right escalator 1B, a plurality of second display plates 43B, ... are used with the convex portion 430 oriented vertically (corresponding to the first shape in claim 1 and the first shape in claim 3).

In display example 4 shown in FIG. 6(b), the left escalator 1A is going up and the right escalator 1B is going down, with the exit 4B of the left escalator 1A and the exit 4B of the right escalator 1B lined up side by side. i) At the exit 4B of the left escalator 1A, multiple second display plates 43B, ... are used with the convex portion 430 oriented horizontally (corresponding to the second shape in claim 1). ii) At the exit 4B of the right escalator 1B, multiple second display plates 43B, ... are used with the convex portion 430 oriented horizontally (corresponding to the second shape in claim 1).

In display example 5 shown in Figure 7 (a), both the left escalator 1A and the right escalator 1B are downward, and the entrance 4A of the left escalator 1A and the exit 4B of the right escalator 1B are lined up horizontally. i) At the entrance 4A of the left escalator 1A, multiple first display plates 43A, ... are used with the convex portions 430 oriented vertically and with the width and height of the convex portions 430 decreasing toward the endless conveying body 20, i.e., with the tips of the convex portions 430 facing the endless conveying body 20 (corresponding to the first shape in claim 1 and the second shape in claim 3). ii) At the exit 4B of the right escalator 1B, multiple first display plates 43A, ... are used with the convex portions 430 arranged horizontally and with the width and height of the convex portions 430 decreasing toward the adjacent entrance 4A on the left, i.e., with the tips of the convex portions 430 pointing toward the adjacent entrance 4A on the left (corresponding to the second shape in claim 1 and the fourth shape in claim 4).

In display example 6 shown in Figure 7 (b), both the left escalator 1A and the right escalator 1B are upward, and the exit 4B of the left escalator 1A and the entrance 4A of the right escalator 1B are side-by-side. i) At the exit 4B of the left escalator 1A, multiple first display plates 43A, ... are used with the convex portions 430 oriented horizontally and with the width and height of the convex portions 430 decreasing toward the entrance 4A to the right, i.e., with the tips of the convex portions 430 pointing toward the entrance 4A to the right (corresponding to the second shape in claim 1 and the third shape in claim 4). ii) At the entrance 4A of the right escalator 1B, multiple first display plates 43A, ... are used with the convex portions 430 oriented vertically and with the width and height of the convex portions 430 increasing toward the endless conveyor 20, i.e., with the tips of the convex portions 430 facing away from the endless conveyor 20 (corresponding to the first shape in claim 1 and the first shape in claim 3).

As described above, according to the escalator 1 of this embodiment, the visually impaired person feels a small sense of resistance in the soles of their feet, whether the convex portion 430 of the display plate 43 has the shape associated with the first display plate 43A (isosceles triangular in plan view) and is vertically arranged, or the shape associated with the second display plate 43B (rectangular in plan view) and is vertically arranged. This allows the visually impaired person to recognize from experience that they may proceed and understand that this is the entrance 4A. On the other hand, whether the convex portion 430 of the display plate 43 has the shape associated with the first display plate 43A and is horizontally arranged, or the shape associated with the second display plate 43B and is horizontally arranged, the visually impaired person feels a large sense of resistance in the soles of their feet. This allows the visually impaired person to recognize from experience that they may not proceed and understand that this is the exit 4B. Therefore, according to the escalator 1 of this embodiment, it is easy to distinguish between the entrance 4A and the exit 4B.

In addition, according to the escalator 1 of this embodiment, the visually impaired person feels less resistance in the soles of their feet when the convex portion 430 of the display plate 43 has the shape and vertical arrangement related to the first display plate 43A or the shape and vertical arrangement related to the second display plate 43B. In addition, the visually impaired person feels different sensations in the soles of their feet when the convex portion 430 of the display plate 43 has the shape and vertical arrangement related to the first display plate 43A and the shape and vertical arrangement related to the second display plate 43B, or when the convex portion 430 of the display plate 43 has the shape and normal vertical arrangement related to the first display plate 43A and the shape and reverse vertical arrangement related to the first display plate 43A. Here, it is assumed that the visually impaired person understands in advance that the shape and vertical arrangement related to the second display plate 43B is a display form corresponding to the uphill direction of the escalator 1, and the shape and normal vertical arrangement related to the first display plate 43A is a display form corresponding to the downhill direction of the escalator 1. Alternatively, it is assumed that the visually impaired person understands in advance that the shape and inverted vertical arrangement of the first display plate 43A is a display form corresponding to the uphill direction of the escalator 1, and the shape and normal vertical arrangement of the first display plate 43A is a display form corresponding to the downhill direction of the escalator 1. Alternatively, the shape and inverted vertical arrangement of the first display plate 43A is a shape that gives the visually impaired person a sense of looking up, and the shape and normal vertical arrangement of the first display plate 43A is a shape that gives the visually impaired person a sense of looking down. In this case, when the convex portion 430 of the display plate 43 is in the shape and vertical arrangement of the second display plate 43B or in the shape and inverted vertical arrangement of the first display plate 43A, the visually impaired person understands that this is the entrance 4A of the uphill escalator 1. On the other hand, when the convex portion 430 of the display plate 43 is in the shape and normal vertical arrangement of the first display plate 43A, the visually impaired person understands that this is the entrance 4A of the downhill escalator 1. Therefore, with the escalator 1 according to this embodiment, it is easy to distinguish whether the direction is up or down.

In addition, with the escalator 1 according to this embodiment, the shape and horizontal arrangement of the first display plate 43A is such that it gives a visually impaired person the sense that they should not proceed and that they should face left or right. The tip of the plate faces the entrance 4A of the adjacent escalator 1. Therefore, with the escalator 1 according to this embodiment, even if a visually impaired person mistakenly enters the exit 4B, the escalator 1 has the effect of guiding the visually impaired person to the entrance 4A.

The present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.

In the above embodiment, a display example has been described in which two escalators 1, 1 are installed side by side, and two boarding and alighting entrances 4, 4 are arranged side by side. However, the present invention is not limited to this. It goes without saying that the present invention can also be applied to the case of a single escalator.

In the above embodiment, there are two first plates 41. However, the present invention is not limited to this. The first plates 41 may be multiple plates, such as three or four plates, or may be a single, large, undivided plate.

In the above embodiment, the display unit is provided on the first plate 41. However, the present invention is not limited to this. The display unit may also be provided on the second plate 45. However, in order to enable visually impaired people to quickly distinguish, it is preferable that the display unit be provided as far away as possible from the endless conveyor.

In the above embodiment, two display plates 43 are used on each of the two first plates 41, 41, for a total of four. However, the present invention is not limited to this. The number and size of the display plates are matters to be determined appropriately depending on the size of the boarding/alighting entrance and the installation situation. Of course, the display plate can be a single, wide, undivided plate.

In the above embodiment, the display plate 43 is sized to fit within the main plate 42 of the first plate 41. However, the present invention is not limited to this. The display plate may be sized to span multiple first plates.

In the above embodiment, the display unit is a display plate 43 that is separate from the main plate 42 of the first plate 41. However, the present invention is not limited to this. The display unit may be integrally formed with the first plate.

In the above embodiment, the passenger conveyor is an escalator. However, it goes without saying that the present invention can also be applied to moving walkways. Note that moving walkways generally transport passengers horizontally, but some also transport passengers at an incline, just like escalators.
