Description

Technical Field

[0001] The present invention relates to a passenger conveyor that conveys passengers by an endless conveyor that circulates and moves.

Background Art

[0002] Passenger conveyors such as escalators and moving walkways include a boarding and alighting section and a conveying section. The boarding and alighting section is located at the start and end of the passage (boarding and alighting openings). The conveying section includes an endless conveyor, and the endless conveyor circulates and moves along the passage to convey passengers. Passengers move from the boarding opening to the start of the endless conveyor (passenger receiving section), board the endless conveyor, are conveyed by the endless conveyor, and then, when they reach the end of the endless conveyor (passenger discharging section), move to the alighting opening and continue moving to leave the passenger conveyor.

[0003] If a passenger moves (walks or runs, the same hereinafter) on the endless conveyor during conveyance by the endless conveyor, there is a risk of contacting other passengers. For this reason, passenger conveyors are premised on conveying passengers without allowing them to stand and move on the endless conveyor. However, allowing passengers to move on the endless conveyor or leaving either the left or right lane of the endless conveyor empty so as not to interfere with the movement of the passengers has become a common practice.

[0004] Therefore, a passenger conveyor has been proposed in which a display device is provided on each step of the endless conveyor, and a guiding display in the form of a pattern consisting of the figure "○" is alternately displayed left and right in the longitudinal direction of the endless conveyor to distribute passengers left and right and suppress the movement of passengers on the endless conveyor (FIGS. 9 and 10 of Patent Document 1).

Embodiments for Carrying out the Invention

[0021] <Overall Configuration> Hereinafter, as embodiments of the present invention, each embodiment of an escalator, which is one of passenger conveyors, will be described. First, prior to this, the overall configuration of the escalator will be described.

[0022] As shown in FIG. 1, the escalator 1 includes a truss (not shown), an entrance / exit 3, a conveying unit 4, a handrail unit 5, and a control unit 6. The truss is a structure that supports the self-weight and the load of the escalator 1. The entrance / exit 3 is provided at the upper portions of both ends of the truss and is located at the ends (starting end, ending end) of the passage. The conveying unit 4 is supported by the truss, and by moving the tread along the passage, it conveys passengers without having them walk while standing in that position. The handrail unit 5 is also supported by the truss and is provided along both sides of the passage along the passage. The control unit 6 controls each part of the escalator 1 and controls the smooth operation of the escalator 1.

[0023] The escalator 1 is set to carry passengers from left to right (from downstairs to upstairs). For this reason, the escalator 1 includes an entrance 3, a conveying unit 4, and an exit from left to right. When the setting is switched reversely by the control unit 6, the entrance 3 is switched to the exit, the exit is switched to the entrance, and it becomes a downward setting for carrying passengers from right to left (from upstairs to downstairs).

[0024] The boarding and alighting opening 3 is provided at the upper part of the horizontal end of the truss. The boarding and alighting opening 3 includes a floor plate 30. The floor plate 30 constitutes the floor of the boarding and alighting opening 3 and is installed at the end (starting end, ending end) of the passage. At the tip of the floor plate 30, a comb-like rubber 31 is attached. The rubber 31 is divided into a plurality in the left-right direction, and each has a rectangular shape (rectangular shape). The plurality of rubbers 31 are arranged side by side in the left-right direction to form a long strip shape along the left-right direction along the tip of the floor plate 30. The tip of the floor plate 30 (the tip of the rubber 31) defines the boundary between the boarding and alighting opening 3 and the conveying part 4.

[0025] The conveying part 4 includes an endless conveyor 40. The endless conveyor 40 is formed by a plurality of steps 41 connected in an endless manner via a step chain 42. The endless conveyor 40 is arranged in the truss so as to be circulatable along the longitudinal direction of the truss. The endless conveyor 40 circulates in one direction or the opposite direction as the step chain 42 circulates with the driving of a driving motor (not shown) arranged in the truss.

[0026] As shown in FIG. 2, the step 41 includes a tread portion 41a, a riser portion (vertical plate portion) 41b, and a yoke portion 41c. The tread portion 41a is plate-shaped along a horizontal plane, and the upper surface thereof serves as a tread surface. The riser portion 41b is plate-shaped and hangs down from the tip of the tread portion 41a, and extends downward while curving in an arc shape. The yoke portion 41c is a reinforcing member that connects the side edge of the tread portion 41a and the side edge of the riser portion 41b. A pair of yoke portions 41c are provided on the left and right.

[0027] The upper surface of the tread portion 41a of the step 41 includes a plurality of ridges 41d. The ridges 41d are provided along the depth direction of the step 41 from the tip to the base end of the tread portion 41a. The ridges 41d are arranged in parallel with a predetermined interval in the width direction of the step 41 and are provided on the entire upper surface of the tread portion 41a. Between the ridges 41d, 41d, there are concave grooves 41e. The concave grooves 41e are provided along the depth direction of the step 41 from the tip to the base end of the tread portion 41a. The concave grooves 41e are arranged in parallel with a predetermined interval in the width direction of the step 41 and are provided on the entire upper surface of the tread portion 41a.

[0028] The step 41 is on the back side and is provided with a partition wall 41f at a position in the middle to the center in the width direction. The partition wall 41f is provided so as to straddle the back surface of the tread portion 41a and the back surface of the riser portion 41b. Where the passage has a left lane and a right lane with a width allowing passengers to stand side by side, the partition wall 41f is provided at the boundary between the left lane and the right lane. The partition wall 41f is provided so as not to interfere with other components when the step 41 moves in a circulating manner, and is provided so as to be close to the light source unit 70 (the light irradiation surface) of the display unit 7 described later.

[0029] As shown in FIG. 3, the handrail portion 5 includes a handrail 50 and a railing 51. The handrail 50, also called a moving handrail, is endless and flexible. The handrail 50 moves in a circulating manner in conjunction with the endless carrier 40. The railing 51 is arranged along the longitudinal direction of the endless carrier 40 on the side of the endless carrier 40. The lower side portion of the railing 51 is supported by the truss 2 and supports the handrail 50 so as to be movable in a circulating manner. The railing 51 includes a railing panel 52, a skirt guard 53, an exterior material 54, and a deck cover 55. A pair of the handrail 50 and the railing 51 are provided along both sides of the passage.

[0030] As shown in FIG. 4, the escalator 1 further includes a display device 7. The display device 7 is provided on the side of the entrance 3 of the passage. The display device 7 includes a light source unit 70. The light source unit 70 is arranged on the back side of the endless carrier 40 (the continuous steps 41). The light source unit 70 is arranged such that the light irradiation surface faces the back surface of the tread portion 41a of the step 41. The light source unit 70 is composed of a first light source unit 70A and a second light source unit 70B. The first light source unit 70A is arranged below the left lane of the passage. The second light source unit 70B is arranged below the right lane of the passage. The light source unit 70 is fixedly arranged in the truss.

[0031] The light source unit 70 is provided in a long shape along the longitudinal direction of the endless conveyor 40 (the moving direction of the steps 41). The light source unit 70 has a length that spans three adjacent (three steps) steps 41A to 41C in the longitudinal direction of the endless conveyor 40. The light source unit 70 includes a plurality of light emitters 70a. The light emitters 70a are arranged at a predetermined interval in the longitudinal direction of the endless conveyor 40. The pitch between the light emitters 70a, 70a is a pitch smaller than the depth dimension of the step 41 (generally about 40 cm), and preferably, two or three or more light emitters 70a are arranged in the depth direction of the step 41 with respect to one step 41.

[0032] As an example, the light emitter 70a is a multicolor LED configured to include red (R), green (G), and blue (B) LED elements. Alternatively, the light emitter 70a is a combination of a red LED and a green LED. Alternatively, the light emitter 70a is a white LED. In any case, the light emitter 70a is individually controlled by the control unit 6, and for each light emitter 70a, lighting, blinking, extinguishing, and the emission color are selected.

[0033] As an example, the light emission pattern 1 is shown in FIG. 5. The light emission pattern 1 is such that a group of light emitters 70a corresponding to either the left lane or the right lane of each step 41 moving on the light source unit 70 lights up or blinks with a predetermined emission color, and the group of light emitters 70a that lights up or blinks switches alternately between left and right for each step 41 in the longitudinal direction of the endless conveyor 40. The light emission pattern 1 lights up or blinks half or approximately half of all the light emitters 70a, and power saving and extended lifespan can be achieved compared to the case of lighting up or blinking all the light emitters 70a (constant lighting or constant blinking). The predetermined emission color is, for example, a single color such as green or white. The group of light emitters 70a that lights up or blinks moves in synchronization with the movement of the step 41 (FIG. 5(a) → FIG. 5(b)), and when focusing on one step 41, the light emission pattern does not change and is fixed.

[0034] Incidentally, since the total length of the endless carrier 40 and the total number of steps 41 are known, and the control unit 6 grasps the moving speed of the endless carrier 40 and the origin position of the endless carrier 40, the control unit 6 can identify the groups of light emitters 70a corresponding to the left lanes and the right lanes of each step 41 moving on the light source unit 70.

[0035] As another example, the light emission pattern 2 is shown in FIG. 6. In addition to the light emission pattern 1, the light emission pattern 2 is a light emission pattern in which the remaining groups of light emitters 70a, that is, the groups of light emitters 70a corresponding to either the left lane or the right lane of each step 41 moving on the light source unit 70 light up or blink in different light emission colors. A predetermined light emission color (the light emitter 70a filled with black in the figure) is, for example, a single green color, and different light emission colors (the light emitter 70a with hatching in the figure) are, for example, a single red color. The groups of light emitters 70a that light up or blink move in synchronization with the movement of the step 41 (FIG. 6(a) → FIG. 6(b)). When focusing on one step 41, the light emission pattern does not change and is fixed.

[0036] As yet another example, the light emission pattern 3 is shown in FIG. 7. The light emission pattern 3 is a light emission pattern in which all the light emitters 70a light up or blink in a predetermined light emission color. The predetermined light emission color is, for example, a single white color.

[0037] In addition to the light source unit 70, the display device 7 is provided with a light-transmitting portion on the tread portion 41a of each step 41. By combining the light emission pattern by the light source unit 70 and the characteristics of the light-transmitting portion, the displays of the following embodiments can be performed.

[0038] <Embodiment 1> <Embodiment 1-1> The display device 7 according to Embodiment 1-1 is a combination of a light emission pattern 1 by a light source unit 70 and a light transmissive portion 41g of the pattern shown in FIG. 8. The display device 7 displays a guidance display 72 by causing the light emitted from a light emitter 70a of the light source unit 70 to be emitted upward from the light transmissive portion 41g via a light guide 71. The light transmissive portion 41g according to Embodiment 1-1 is formed in each of the left lane and the right lane of each tread plate 41. The pattern of the light transmissive portion 41g and the display 72 according to Embodiment 1-1 is a pattern consisting of the figure of "○". The light transmissive portion 41g (light guide 71) according to Embodiment 1-1 is colorless and transparent.

[0039] The light transmissive portion 41g is composed of a through hole 41h and a closing body 71b. The through hole 41h is a hole that penetrates the front and back of the tread portion 41a at the location of the concave groove 41e of the tread portion 41a, and is formed at a plurality of locations in an arrangement that constitutes a pattern. The closing body 71b is a convex portion that protrudes from the upper surface of the base portion 71a of the light guide 71, is inserted into the through hole 41h, and closes the through hole 41h. The light guide 71 is arranged along the back surface of the tread portion 41a and is arranged between the tread portion 41a and the light irradiation surface of the light source unit 70. The light guide 71 is made of, for example, a hard and transparent resin and has light transmissivity.

[0040] According to the display device 7 according to Embodiment 1-1, the guidance display 72 is displayed alternately left and right for each tread 41 in the longitudinal direction of the endless conveyor 40. Passengers tend to stand close to one of the left lane or the right lane according to habit and hesitate to stand on the other, but due to the presence of the guidance display 72, passengers are induced to stand on the guidance display 72 without hesitation, and alternate left and right boarding is realized. Then, due to alternate left and right boarding, both the left lane and the right lane of the passage are blocked by passengers, so the movement of subsequent passengers is suppressed.

[0041] <Embodiment 1-2> The display device 7 according to Embodiment 1-2 is a combination of a light emission pattern 1 by a light source unit 70 and a light transmission part 41g of the pattern shown in FIG. 9.

At the location where the non - display 77 is displayed, since the light irradiated from the light emitter 70a cannot pass through the light transmissive portion 41i, the guidance display 75 does not appear.

[0054] <Effects according to each embodiment> According to the display device 7 according to Embodiments 1 to 6, it is not necessary to provide a display device on each tread 41, and a simple configuration can be achieved. Therefore, according to the display device 7 according to Embodiments 1 to 6, the display device can be realized at low cost.

[0055] According to the display device 7 according to Embodiments 1 to 6, the light source unit 70 is provided for at least two adjacent steps 41 in the longitudinal direction of the endless carrier 40, and the same type of display (guidance displays 72, 75) is distributed and displayed left and right in the longitudinal direction of the endless carrier 40. Therefore, according to the display device 7 according to Embodiments 1 to 6, passengers can be distributed left and right, and the movement of passengers on the endless carrier 40 can be suppressed. In particular, according to the display device 7 according to Embodiments 1 to 6, the guidance displays 72, 75 are alternately displayed left and right for each step 41 in the longitudinal direction of the endless carrier 40. Therefore, according to the display device 7 according to Embodiments 1 to 6, it is possible to guide passengers to alternate left and right rides.

[0056] According to the display device 7 according to Embodiments 2, 4 to 6, in addition to the guidance displays 72, 75, non-displayable areas 73, 77 are displayed on the opposite side of the step 41. Therefore, according to the display device 7 according to Embodiments 2, 4 to 6, passengers can more clearly recognize the position where they are standing, and a more reliable alternate left and right ride can be realized.

[0057] According to the display device 7 according to Embodiments 1 to 6, in the light-transmitting portions 41g, 41i, 41k, the through-holes 41h, 41j, 41m are blocked by the blocking bodies 71b, 74b, 76b. Therefore, according to the display device 7 according to Embodiments 1 to 6, it is possible to prevent dust and the like from falling into the truss 2 through the through-holes.

[0058] According to the display device 7 according to Embodiments 1, 2, 6, the light-transmitting portions 41g, 41i, 41k are formed symmetrically about the center in the width direction of the step 41, so there is no room for arbitrariness on the left and right, and no attention needs to be paid to the arrangement or placement of the steps 41 when installing the steps 41. Therefore, according to the display device 7 according to Embodiments 1, 2, 6, it is sufficient to manufacture one type of step 41.

[0059] <Other Embodiments> Note that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present invention.

[0060] In the above-described Embodiments 1 to 6, the display device 7 (light source unit 70) is provided on the side of the entrance 3 of the passage. However, the present invention is not limited to this. The display device may be provided not only on the entrance side of the passage but also, for example, at an intermediate position of the conveyance unit instead of on the entrance side of the passage.

[0061] In the above-described Embodiments 1 to 6, the light source unit 70 is provided for a plurality (three steps) of steps 41. However, the present invention is not limited to this. The light source unit may be provided for one (one-step) step. Further, even in the case of a plurality, it may not be three steps but two steps, four steps, or five or more steps.

[0062] In the above-described Embodiments 1 to 6, the light source unit 70 is provided in a long shape for a plurality of steps 41. However, the present invention is not limited to this. The light source unit may be provided for each one step and may be composed of a plurality of light source units in the longitudinal direction of the endless conveyor.

[0063] In the above-described Embodiments 1 to 6, the display device 7 alternately displays the guide displays 72 and 75 on the left and right in the longitudinal direction of the endless conveyor 40. However, the present invention is not limited to this. The display device may display the guide display on the left and right at some steps. Further, the display device may alternately display the guide display on the left and right for every two or three steps in the longitudinal direction of the endless conveyor, such as left-left, right-right, left-left, or left-left-left, right-right-right, left-left-left.

[0064] In the above-described Embodiments 1 to 6, the first light source unit 70A and the second light source unit 70B are used corresponding to the left and right lanes. However, in Embodiments 3 and 4 above, when using the light emission pattern 3 shown in FIG. 7, it is not essential that the light source unit be divided into two corresponding to the left and right lanes, and one light source unit may be used.

[0065] In the above-described Embodiments 1 to 6, a multicolor LED is used as the light emitter (point light source). However, when using the light emission pattern 1 shown in FIG. 5 or the light emission pattern 3 shown in FIG. 7, a single-color LED may be used, and when using the light emission pattern 2 shown in FIG. 6, a combination of single-color LEDs of two colors (for example, red and green) may be used. Further, instead of an LED, other light emitters such as a lamp may be used.

[0066] In the above-described Embodiments 1 to 6, the corresponding light emitter 70a lights up or blinks (note that the broad sense of "lighting up" specified in claim 1, which includes "blinking", is not the narrow sense of "lighting up"). That is, the corresponding light emitter 70a either lights up or blinks. However, the present invention is not limited to this. For example, among the light source units 70, the light emitters 70a in a predetermined range from the boarding gate 3 side may blink, and the light emitters 70a in the remaining range may light up (in the narrow sense). In this case, in a predetermined number (for example, one or two) of steps 41 on the boarding gate 3 side, the guide displays 72 and 75 are emphasized by blinking, and in the steps 41 beyond that, the guide displays 72 and 75 are calmed by lighting up.

[0067] In the above-described Embodiments 1 to 6, the patterns of the light-transmitting portions 41g, 41i, and 41k are formed in a part of the left half region or the right half region of the step 41. However, the present invention is not limited to this. The pattern may be formed over the entire half region of the step. Also, various forms of the pattern can be adopted.

[0068] In the above-described Embodiments 1 to 6, in order to prevent dust and the like from falling, the through holes 41h, 41j, and 41m are blocked by the blocking bodies 71b, 74b, and 76b. However, the present invention is not limited to this. If there is no problem with dust and the like falling, the blocking body is not essential. However, in the above-described Embodiments 4 and 6, the blocking bodies 74b and 76b also function as color conversion means for the light-transmitting color. Therefore, when eliminating the blocking bodies 74b and 76b in the above-described Embodiments 4 and 6, separate color conversion means such as a color filter are required.

[0069] In the above-described Embodiment 4, the pattern and the light-transmitting color are made different between the light-transmitting portion 41i in the left lane and the light-transmitting portion 41k in the right lane. However, the present invention is not limited to this. The light-transmitting colors may be different in the same manner, but the pattern may be the same on the left and right as in Embodiment 1.

[0070] In the above-described embodiment, the passenger conveyor is an escalator. However, it goes without saying that the present invention can also be applied to a moving walkway. Note that moving walkways include those provided with a step-type endless conveyor and those provided with a belt-type endless conveyor (endless belt-like conveyor).

[0071] For example, unless it physically interferes, such as integrating the pattern of Embodiment 1-3 shown in FIG. 10 with the pattern of Embodiment 1-1 shown in FIG. 8 or the pattern of Embodiment 1-2 shown in FIG. 9, applying the above-described technical elements to other embodiments or examples, replacing the above-described technical elements with technical elements related to other embodiments or examples, combining the above-described technical elements with each other, etc. are naturally possible, and this is what the present invention naturally intends.
