FIG. 1 is a perspective view of an escalator device 1 according to an embodiment of the present invention, with a portion cut away. The escalator device 1 is provided from the lower floor 9 to the upper floor (not shown). The endless movable floor 3 is connected to a plurality of treads 2 on which the user is mounted, and is driven to travel in a predetermined traveling direction A. A pair of hollow balustrades 4 provided at both ends of the movable floor 3, a lower floor side getting on / off step 18 which is arranged on the lower floor 9 and transfers to the movable floor 3, and is arranged on the upper floor, And a step of getting on and off the upper floor not shown. Endless handrails 6 are provided on the outer periphery of each balustrade 4, and these handrails 6 are driven to run following the movable floor 3. The movable floor 3 is a movable floor mounting area on which the user is mounted,
That is, the upper part of the endless movable floor 3, that is, the area facing the outside is driven to travel in the traveling direction A indicated by the arrow A in FIG. 1, and is moved from the step 18 on the lower floor side to the lower end of the movable floor 3. The occupant can be raised to the upper floor. Conversely, by driving the movable floor 3 to move in the loading area in the direction of the arrow B opposite to the direction of the arrow A,
The user who gets on the upper end of the movable floor 3 from the getting on / off step on the upper floor side can be lowered to the lower floor 9.

At the lower end of each balustrade 4, skirt portions 7 projecting toward the movable floor 3 and extending along the traveling direction A are formed, and are substantially vertically upward from both ends of the mounting area of the movable floor 3. A plurality of openings 10 are formed in the pair of side walls 8 of the skirt portion 7 rising and extending along the traveling direction A of the movable floor 3 along the longitudinal direction of the side walls 8.
Is formed, and a cover plate 21 in which a plurality of pores 22 are formed is fitted into each opening 10. The opening 10 is
It is a long hole extending along the traveling direction A, and is formed at a position close to the tread 2, that is, facing a foot of a user who rides on the tread 2.

In each balustrade 4, a discharge air guide means 12 is provided. The discharge air guide means 12 supplies air discharged from a blast source 11 which discharges air of a predetermined temperature to each opening 10 of each side wall 8. Guiding, above the loading area of the movable floor 3,
And the air supply source 1 is directed toward the space sandwiched between the side walls 8.
The air discharged from 1 is discharged. Discharge air guide means 1
2 extends in the longitudinal direction of the side wall 8 in the balustrade 4, that is, along the traveling direction A, and has an opening 19 at one end on the downstream side in the traveling direction A, through which air discharged from the air supply source 11 is introduced;
A duct 16 whose other end in the longitudinal direction is closed;
And a plurality of communication pipes 17 that communicate with the respective openings 10.

The air supply source 11 includes a heat pump having an evaporator and a condenser. For example, in winter, heat is taken from the outside air by the evaporator, and the heat is discarded from the condenser to warm the air. Discharge air guide means 1
To the cover plate 2 from each opening 10 of the side wall 8.
The warmed air is discharged through one of the fine holes 22. In summer, the switching valve provided in the compressor of the heat pump is switched to reverse the circulation direction of the refrigerant. Then, the evaporator works as a condenser, and the condenser works as an evaporator.The heat taken by the evaporator is discarded to the outside by the condenser, the heat is taken away, and the cooled air is discharged by the fan to the discharge air guide means. 12 will be supplied. Thereby, in summer, the pores 2 of the cover plate
The cold air is discharged through the second cooling air. Therefore,
Even if the escalator device 1 is installed in a place such as a station or a park that comes into contact with the outside air, warm air is discharged to the feet of the user in winter and cool air is discharged to the feet of the user in summer to comfortably. You can ride. Such a blast source 1
As the first heat pump, an absorption refrigerator having no compressor may be used.

When heat in the air is removed by a heat pump in the summer, moisture is also removed along with the heat, so that dehumidified cool air is discharged from each opening 10 of the side wall 8. Since the humidity becomes particularly high in summer, the dehumidified cold air is blown to the feet, so that the escalator device 1 can be more comfortably loaded. The air supply source 11 may be provided with a humidifier so that the humidified warm air is discharged from the openings 10 of the side walls 8 in winter. Thereby, getting on and off the escalator device 1 in winter with low humidity becomes more comfortable.

The air supply source 11 is not limited to the above-described heat pump, but may be a boiler having a fan, for example. In the winter, it is possible to warm the feet by discharging the air heated by the boiler to the feet for elderly people who are particularly burdened by the stimulus of cold outside air. In the summer, the boiler may be stopped, and a fan may blow air from each opening 10 to the feet. Thereby, for example, even if the treads are heated by being exposed to direct sunlight, the hot air is diffused by the blowing and the feet are cooled by blowing the wind to the feet. In this manner, the feet of the user can be warmed in winter at low cost, and particularly the elderly can comfortably ride on the escalator device 1.

The escalator device 1 may be provided with a temperature sensor for detecting the temperature of the outside air, and the blast source 11 may be driven according to the temperature sensor. For example,
When the outside air reaches a predetermined temperature, for example, less than 18 ° C., hot air is discharged from each opening, and when the outside air reaches a predetermined temperature, for example, 28 ° C. or more, cold air is discharged from each opening 10. For example, it may be configured to control only stopping or blowing.

The sound generating means 15 has a speaker device 13 provided at one end in the longitudinal direction of the duct 16 and a sound generating source 14, and generates a predetermined sound in the duct 16 of the discharge air guiding means 12. . The sound source 14
A reproducing apparatus for a recording medium such as a compact disk or a cassette tape and an amplifier are provided, and the speaker device 13 can generate audio information such as music or voice. Since the speaker device 13 is provided at one end of the duct 16, that is, at the upstream end in the blowing direction of the air discharged from the blowing source 11, the sound generated from the speaker device 13 is conveyed to the air discharged from the blowing source 11. Side wall 8
Is discharged from each of the openings 10. Therefore, sound can be emitted from each opening 10 without providing a speaker device in each opening 10. Thereby, even if the user riding on the tread 2 is moving from the lower floor 9 to the upper floor, sound is emitted from each opening 10 provided along the traveling direction of the movable floor 3, The user can always obtain acoustic information from the opening 10 without interruption on the moving path from the lower floor 9 to the upper floor. As a result, for example, even a large amount of information that cannot be heard by acoustic information from a speaker provided only at one location can be reliably heard.

The sound source 14 may not only generate sound from a recording medium, but also make an announcement in real time by a microphone, for example. The speaker device 13 is provided not only at one position at one end of the duct 16 but also at the center of the duct 16 or in the traveling direction A.
The speaker device 13 may be provided near the downstream, that is, on the upper floor side of the duct 16. This allows the user to reliably hear the acoustic information even near the upper floor.

For example, there is no problem if a speaker is provided on the ceiling and sound can be generated so that all users of the escalator device can hear the sound. However, there is no ceiling and the speaker cannot be easily provided outside. Also, when a large volume is generated and annoying other than the escalator user is troubled, it is difficult to transmit acoustic information to all the users by one speaker. However, by providing the sound generating means 15 of the present invention, sound information can be reliably transmitted to all users of the escalator device 1 by one or a small number of speakers.

An illumination means such as a fluorescent lamp may be provided in each opening 10 or in the vicinity of the opening 10 so as to illuminate the user's feet at night. Further, a red light emitting diode and a green light emitting diode are provided in the opening 10, for example, such that the red light emitting diode emits light when hot air is discharged from the opening 10, and the green light emitting diode emits light when cold air is discharged from the opening 10. May be. Thus, the user can easily visually recognize that the air supply source 11 is being driven.

When the user gets on the movable floor 3 from the step 18 on the lower floor side, air is discharged from the opening 10 of each side wall 8 together with sound toward the user's foot. The caution is prompted, and the user moves while paying attention to his / her feet, so that the user can safely transfer to the movable floor 3 from the getting on / off step 18. Further, the air is discharged from the opening 10 at the foot of the user, so that the user is prevented from being too close to the side wall 8 slidably in contact with the movable floor 3. And clothes are prevented from being pinched, and safety is improved.

FIG. 2 is a sectional view taken along line II-II of FIG. The duct 16 has a rectangular cylindrical shape, and a communication pipe 17 is provided from the bottom 30 of the duct 16 to the opening 10 of the side wall 8.
6 and the opening 10 are communicated. The communication pipe 17 is the duct 1
6, the one end 17 a is connected to the opening 10 almost perpendicularly, and the air in the duct 16 is smoothly curved from the opening 1.
It can be discharged from 0 through each pore 22 of the cover plate 21. The cover plate 21 is made of, for example, a stainless steel plate, fits into the opening 10 formed in the side wall 8 as shown in FIG. 2, and a fitting portion 23 in which a plurality of pores 22 are formed is formed to be convex by pressing. And
The fitting portion 23 is formed from the inside of the skirt portion
And the periphery of the cover plate 21 is fixed to the side wall 8 from the inside by welding or the like. When the cover plate 21 is attached to the side wall 8 in this manner, the fitting portion 2
The outer surface of 3 is flush with the outer surface of the side wall 8 to prevent the clothes or umbrella of the user from being caught in the gap between the cover plate 21 and the opening 10. Further, the diameter of each of the fine holes 22 formed in the cover plate 21 is formed to be less than 5 mm, and it is possible to prevent a user, for example, an umbrella tip, from entering the fine holes 22.

The other end 17b of the communication pipe 17 on the duct 16 side
Is reduced in diameter to form an orifice 25. Such orifices 25 are all formed in the respective communication pipes 17, and are formed such that the opening area of the orifices 25 sequentially increases toward the downstream side in the blowing direction in the duct 16, that is, toward the upper floor. The air pressure is high in the airflow direction upstream of the duct 16 connected to the airflow source 11 and the air pressure is low in the duct 16 downstream in the airflow direction. However, the communication pipe 17 on the upstream side in the airflow direction has a small opening area formed by the orifice 25. Since the opening area of the communication pipe 17 on the downstream side in the blowing direction is formed to be large by the orifice 25, the amount of air discharged from each opening 10 becomes substantially equal.
It is possible to prevent the amount of air discharged from the air from being reduced. This also ensures that the sound conveyed with the air is also discharged from the opening 10 on the downstream side in the blowing direction.

FIG. 3 is a sectional view showing a communication pipe 31 of another embodiment. In the communication pipe 31, one end 3 connected to the opening 10
1a is not connected to the side wall 8 almost vertically like the communication pipe 17a shown in FIG. 2, but one end 17a is inclined upward as shown in FIG. Is done. In addition, the discharge direction is divided into three stages of upper, middle, and lower, and air is discharged toward the waist of the user from the communication tube 31 inclined at the highest position, and the user is discharged from the communication tube 31 whose discharge direction is the middle stage. The air is discharged toward the knee, and in the case of the communication pipe 17 which is connected to the lowermost part, that is, substantially perpendicular to the side wall 8 as shown in FIG. 2, the air is discharged toward the ankle of the user. , May be provided in each of the openings 10 along the traveling direction A. With this configuration, in the winter season, warm air is sequentially discharged toward the user's ankle, knee, and waist, and the user is warmed not only at the feet but also at the entire lower body, and the user, particularly the elderly, is comfortable. You can get on.

FIG. 4 is a sectional view showing the vicinity of one end of the discharge air guiding means 12. As shown in FIG. The duct 16 of the discharge air guide means 12 is smoothly curved downward near one end where air from the air supply source 11 is introduced, and a speaker device 13 is provided outside the curved portion. The housing 26 of the speaker device 13 has a bottomed cylindrical shape, is substantially coaxial with the axis of the duct 16, has an opening facing the inside of the duct 16, and is airtightly connected to the duct 16. A speaker 27 is fixed in the housing 26 so as to face the duct 16.
Sound is generated from inside the duct 16. A filter 29 for preventing dust from entering the housing 26 from the duct 16 is provided at an opening of the housing 26. The sound source 14 is connected to the speaker 27.

A rectifying member 28 is provided in the opening 19 of the duct 16 into which the air discharged from the air supply source 11 is introduced. The rectifying member 28 is a member in which the plate-shaped pieces 20 are combined in a lattice shape so that the cross-sectional shape becomes a grid shape. The rectifying member 28 is fitted and attached to the opening 19 of the duct 16. The air introduced from the air supply source 11 when such a rectifying member 28 is not provided has a different flow velocity between the vicinity of the peripheral wall of the duct 16 and the vicinity of the central portion. The flow velocity in the vicinity of each plate-like piece 20 combined with the above is substantially equal, and it is prevented that the flow velocity is different between the vicinity of the peripheral wall of the duct 16 and the vicinity of the central portion as described above. Air will flow. By sending the air uniformly, the sound generated from the speaker 27 is also conveyed almost uniformly, and it is possible to prevent the sound from being difficult to hear. Such a rectifying member 28 may be provided not only at one end of the duct 16 but also at a plurality of places in the duct 16. As a result, the flow of air in the duct 16 becomes more uniform.

FIG. 5 is a partially cutaway front view showing an escalator device 40 according to another embodiment of the present invention. The components corresponding to the escalator device 1 are denoted by the same reference numerals, and a pair of balustrades 4 formed substantially symmetrically.
With respect to the configuration (1), the configuration on one side (left side in FIG. 5) is denoted by reference numeral a, and the configuration on the other side (right side in FIG. 5) is denoted by reference numeral b. The escalator device 40 is different from the escalator device 1 in that the air blown from the blower source 11 is not introduced into both the discharge air guide means 12a and 12b in the balustrades 4a and 4b, but the discharge air guide means on one side. Opening 19a of duct 16a of 12a
The opening 19b of the duct 16b of the discharge air guide means 12b on the other side communicates with the suction port of the fan in the air supply source 11. Therefore, the air discharged from the air supply source 11 and discharged from each opening 10a of the one side wall 8a is sucked from each opening 10b of the other side wall 8b. That is, when the heated air is discharged from the opening 10a of the one side wall 8a, the heated air is sucked again and heated, so that the outside air is heated more efficiently than when newly heated. Energy efficiency is improved. The same applies to the case of discharging cool air in summer. Such a configuration is particularly effective when the number of users is small, and the directly discharged air is sucked from one opening 10a to the other opening 10b without the intervention of the user.

The endless movable floor 3 of such an escalator device 1 is folded downward from the loading area of the user at the upstream and downstream ends in the traveling direction A. May be a general escalator device in which the folded tread plate 2 is turned upside down, but when the tread plate 2 is turned upside down, the ride surface on which the user rides is turned upward. You may be comprised so that it may be turned over in the state which was set. Thereby, the escalator device 1 can be made thinner, and can be suitably implemented as a simple escalator device. Such a simple escalator device can be easily installed on an existing staircase provided outdoors, for example, at a station or a park. Also, the same effect as when installed outdoors can be achieved even when installed on a home staircase.

[0028]

As described above, according to the present invention, a plurality of openings are formed in the side walls extending along the traveling direction of the movable floor at both ends of the movable floor along the longitudinal direction. Air is discharged from the air supply source via the discharge duct, and returned to the air supply source from the suction duct. Therefore, in the winter, for example, by discharging warm air from each opening, the feet of the user are warmed and the escalator device can be comfortably boarded. Also, in the summer season, the escalator device can be comfortably mounted by discharging cool air from each opening. In addition, energy efficiency is improved by sucking and collecting the discharged air.

Further, according to the present invention, the predetermined sound is generated in the discharge air guiding means by the sound generating means, so that the generated sound is conveyed to the air from the blowing source and provided along the traveling direction. Are discharged together with the air from the respective openings. Therefore, sound can be generated from each opening without providing a plurality of sound generating means. Furthermore, since a plurality of openings are provided along the traveling direction, the user can always hear acoustic information from each opening even when the user is riding on the movable floor and traveling. As a result, the user can obtain a large amount of acoustic information. In addition, air is discharged with sound from the opening, so that the user is alerted to his feet when riding on the movable floor,
Thereby, the user can safely transfer to the movable floor that is driven and driven. In addition, since the air is discharged together with the sound from the opening formed in the side wall, the user is prevented from approaching the side wall by an instinctive alertness that the user closes the opening when the user approaches the side wall too much. This prevents the user from approaching the vicinity of the end of the tread that inevitably slides on the side wall, thereby improving safety.
