Abstract

PROBLEM TO BE SOLVED: To simplify a current-carrying structure to the display part by interlockingly connecting generators with/to wheels, and displaying the display part installed on footboards by generating electric power in an elscalator having freely rotatable wheels on longitudinal directional one both sides of the footboards arranged in a plurality in the escalator. SOLUTION: A pair of wheels 9 are respectively rotatably arranged on both sides of plural footboards 6 connected in an endless shape so that the respective wheels 9 are rollingly guided along a footboard rail. In this case, while generators 16 are arranged on respective footboards 6, LEDs 27 are installed on the upper surfaces of the footboards 6 so that the generators 16 are connected to the LEDs 27 through a circuit board 14 having a weight switch 28. When operating an escalator, electric power is generated by rotating output shafts of the generators 16 since the wheels 9 roll on the footboard rail. When the weight switch 28 is put in a closed state on the footboard 6-exposed passenger side, the LEDs 27 are made to emit the light. While, the LEDs 27 are put out by opening the weight switch 28 on the footboard 6-reversing reversal side.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator, in which an LED or the like is mounted on a tread.

[0002]

2. Description of the Related Art Escalators are used to transport people between two different heights. FIG. 5 shows a structure of a conventional escalator. As shown, sprockets 1 and 2 are provided, and a tread chain 3 is wound between the sprockets 1 and 2. The sprockets 1 and 2 and the tread chain 3 are provided as a pair in a direction perpendicular to the paper surface.
The tread chain 3 has a link 4 rotatably connected via a hollow pin 8 as shown in FIG. 6, and the hollow pin 8 is provided with a roller 5 rotatably. A tread plate 6 is arranged without a gap between the pair of tread plate chains 3, and both ends of a shaft 7 inserted through the tread plate 6 are inserted into hollow pins 8. A pair of wheels 9 is provided on both sides of the tread plate 6 so as to be freely rotatable. In order to place and guide the rollers 5 and the wheels 9, tread rails (not shown) are individually provided.

A pair of sprockets 1 are fixed to a drive shaft (not shown), and the drive shaft is connected to a motor 13 via a speed reducer 12.

[0004] In addition, an endless moving handrail 14 is provided, and the moving handrail 14 is linked to a motor 13 so as to move at the same speed as the tread chain 3 in the direction of the arrow.

[0005] The rotation of the motor 13 is reduced by the speed reducer 12 and transmitted to the pair of sprockets 1. Then, the tread chain 3 moves in the direction shown by the arrow. For this reason, while the roller 5 and the wheels 9 roll on the individually provided tread rails, the tread 6 moves diagonally upward, while rolling on the other tread rails (not shown) provided separately, diagonally downwards. And move. Four pairs of tread rails are provided as described above, and each pair of tread rails has a U-shaped cross-sectional shape, and has a structure in which mutually facing surfaces are opened to prevent derailment.

[0006]

However, when a demarcation lamp or the like is mounted on the tread plate 6, since the tread plate moves, it is necessary to provide a portion that conducts electricity while sliding to guide the power supply to the tread plate. With difficulty.

[0007] Therefore, an object of the present invention is to provide an escalator that solves the above problem.

[0008]

According to a first aspect of the present invention, there is provided an escalator comprising: a pair of sprockets provided at two points having different heights; A plurality of treads on which a person is placed is arranged between the tread chains having rollers wound around the tread chain arranged substantially parallel to each other over the entire length of the tread chain, and one side of each tread plate in the front-rear direction. In the escalator, which is rotatably mounted on the tread chain, provided with rotatable wheels on the other side, separately provided tread rails for the rollers and wheels to roll, and driving means linked to the sprocket. A generator is interlocked to the wheel, and a display unit is attached to the tread plate. The tread plate is closed when the tread plate is exposed, and is opened when the tread plate is not exposed and the tread plate is inverted. Characterized in that connects the generator and the display unit via a switch.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. In this embodiment, since a part of the conventional escalator is improved, the same parts as those of the conventional escalator are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

(A) Embodiment 1 Embodiment 1 of an escalator according to the present invention is shown in FIGS. As shown in FIG. 1, a generator 16 is attached to the tread 6, and an LED as a display unit is provided on the top of the tread 6.
(Light emitting diode) 27 is attached, and the generator 16 is connected to the LED via the circuit board 14 having the weight switch 28.
27.

First, the generator 16 will be described. The generator 16 is linked to only one of the pair of wheels 9. As shown in FIG. 2, a generator 16 is attached to a leg 6 a of the tread plate 6 via a spacer 15 with a bolt 17. The generator 16 includes a generator body 16a and a holder 16b. A roller bearing 18 is provided on the leg 6a.
The rotation shaft 19 is rotatably supported via the
A roller 9 is fixed to the roller. A small-diameter portion is formed at the end of the rotating shaft 19, and the small-diameter portion is fitted in a hole formed in the input shaft 20 of the generator main body 16 a and is prevented from coming off by a bolt 21. By forming a large hole 15a in the spacer 15, the rotation of the bolt 21 is not hindered.

Next, the LED 27 will be described. In this embodiment, an LED 27 is used as a display unit connected to the generator 16.
Is used. A plurality of LEDs 27 are provided along the demarcation line.

Next, the weight switch 28 will be described. The weight switch 28 includes the first electrode 23 and the second electrode 2.
4 and an insulating member 2 interposed between these two electrodes
5 and a sphere 26 formed of a conductive material. Then, both surfaces of the combined state of the first electrode 23 and the second electrode 24 are covered with an insulating plate (not shown).

The LED 27 and the generator 16 are connected to the tread plate 6.
It may be provided on every other or every third or on all the treads 6.

Next, the operation of the escalator will be described. As in the conventional case, the output shaft of the motor 13 rotates, is decelerated by the speed reducer 12, and the tread chain 3 moves on a tread rail (not shown). Then, the wheels 9 also roll on the tread rails, so that the output shaft 20 of the generator 16 linked to the one wheel 9 rotates to generate electricity.

In the present embodiment, when the uphill operation is performed on the passenger side where the tread plate 6 is exposed, as shown in FIG.
4 comes into contact with each other, and is in a “closed” state. Accordingly, when the tread 6 rises, the LED emits light, and the position of the dimerization line becomes clear.

On the other hand, when the tread plate 6 is on the reversing side where the reversing is performed, and in this embodiment, on the return side of the up operation, FIG.
As shown in (b), the sphere 26 comes into contact with only the second electrode 24 to be in an “open” state. Therefore, the display unit is not added to the generator 16 and the LED 27 does not light.

(B) Embodiment 2 Next, Embodiment 2 of the escalator according to the present invention is shown in FIG. In this embodiment, the name of the manufacturer of the escalator is displayed on the upper surface of the tread plate 6 by the LED 27, and an arrow for indicating that the escalator is an ascending escalator is displayed on the front. In addition, the name of the store to which the escalator is attached may be displayed instead of the name of the manufacturer.
Instead of the arrow, an LED 27 may be provided as illumination for illuminating the upper surface of the tread 6 located below the tread 6.

The other configuration and operation are the same as those of the first embodiment, and the description is omitted.

In the first and second embodiments, the generator is connected to only one of the wheels. However, the generator may be provided to both of the wheels. Although an LED is provided as the display unit, music or a voice message can be played by providing a means for generating a voice instead of the display unit. Furthermore, in the present invention, a generator or the like is provided on an escalator for transporting a person between two points having different heights, but the present invention is applied to a "moving sidewalk" for transporting a person between two points having substantially the same height. The invention can also be applied.

[0021]

As can be seen from the above description, claim 1
According to the escalator according to the above, the generator is interlocked to the wheels rolling on the tread rail, and the generator is connected to the display unit via the weight switch. The switch closes and current flows through the display. Therefore, it is not necessary to use a motor having a large driving force for driving the escalator without wasteful power generation. In addition, since the generator is linked to the existing wheels, there is no need to guide the power supply to the tread via the sliding portion, and there is no need to make a separate system for turning the generator.
