Abstract

PROBLEM TO BE SOLVED: To provide footstep cleaning equipment for an escalator wherein a device is miniaturized and usable for both up and down operation. SOLUTION: A supporting arm 7 of footstep cleaning equipment 6 is fixed to an inner side plate 3 by a suction apparatus 14, fitted to one end thereof, so as to be parallel with a footstep. A rotating level 8 is fitted to the other end of the supporting arm 7 so as to be able to oscillate around a fulcrum supporting shaft 9 as a fulcrum, and a roller brush 10 is rotatably fitted to the tip of the rotating lever 8 so that its rotary shaft is parallel with the footstep, that is, the roller brush 10 is rotatbly fitted to the tip of the rotating lever 8 by a pivotal shaft with a friction roller 11 fitted to the tip. When the friction roller 11 is rotated, friction is generated to the respective faces of a tread 1 and a riser face 2, so that the rotation of the pivotal shaft is partially limited. As a result, the rotation of the roller brush 10 is partially limited, and the roller brush 10 is rotated in such a way as to sweep the tread 1 and riser face 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool for steps of an escalator, and more particularly to a cleaning tool for steps of an escalator which is attached to an inner plate (skirt portion) of the escalator to clean steps and steps of the riser.

[0002]

2. Description of the Related Art FIG. 8 schematically shows steps of an escalator. As shown in FIG. 8, the step includes a tread 1 that is a tread and a riser 2 that is a riser of the step. The inner plate 3 of the balustrade of the escalator is made of tempered glass or stainless steel plate. Skirt guards 4 are provided below the inner plate 3 and on both side surfaces of the steps so as to face the steps with a constant gap. An inner deck 5 is arranged inside the lower part of the inner plate 4.

Conventionally, the steps of an escalator generally have dirt or sand adhering to the footwear of passengers, fibers of clothes dropped when getting on or off, or dust carried by ventilation. In particular, the soil and the like are concentrated and attached to the tread 1 and the riser 2, especially the end side portions 1a and 2a on both sides thereof. Furthermore,
In normal climbing operation, the surface of the riser 2 is easily visible, so that the deposits are more easily noticed by passengers, and it is necessary to remove the deposits for climbing operation.

Conventionally, a maintenance worker uses a simple cleaning tool such as a broom 30 or a vacuum cleaner to remove the above-mentioned deposits from the tread 1 and the riser 2 before and after using the escalator and during maintenance. It was manually cleaned.

Therefore, the maintenance work takes a long time, and the operator is troubled.

Therefore, in recent years, for example, JP-A-61-2734.
No. 89, "Escalator Step Elevator Cleaning Device", the rod-like brush member for cleaning the step elevator of the escalator is fixed to an arm mechanism so as to elastically press against the elevator. There is proposed a cleaning device in which an arm mechanism is stretched and held on both side walls near the handrail belt. Further, the rod-shaped brush member is rotated by a drive motor, and the steps are cleaned by the rod-shaped brush member while automatically operating the escalator.

Further, in the "passenger conveyor step cleaning device" of Japanese Patent Publication No. 1-44636, a cleaning tool (a channel brush) is attached to a supporting arm, and a supporting lot for rotatably supporting the supporting arm is provided on both sides. A step cleaning device has been proposed which is attached and fixed to a balustrade member and which cleans the steps with a cleaning tool while automatically operating the escalator.

[0008] Further, in "Escalator Step Riser Sliding Agent Coating Device" of Japanese Utility Model Laid-Open No. 2-91776,
The left and right arms hold a member facing the riser of the escalator step, parallel to its width direction, and having a brush attached along its lengthwise direction, and the left and right arms can rotate on the immovable surface of the escalator. There is proposed a device which is supported and cleans the steps with a brush while automatically operating the escalator.

[0009]

However, any of the devices proposed in the above publication has a problem that the device configuration is large and it is not easy to carry. In addition, since all the devices are complicated to attach and detach, and the rotation direction of the support arm to which the brush is attached is limited, the device is of a type that can be used only in the down operation. Therefore, there is a problem that the working direction is limited to one direction and lacks versatility. That is, it could not be used in the case of an escalator for uphill only operation.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a step cleaning tool which can be downsized and can be used for both up and down driving operations.

[0011]

In order to solve the above problems, a cleaning tool for steps of an escalator according to the present invention has the following features.

(1) A support arm fixed to an inner plate of the escalator by an adsorber attached to one end of the escalator so as to be parallel to the steps of the escalator, and swingably attached to the other end of the support arm. A rotary lever, and a roller brush rotatably attached to the tip of the rotary lever so that the step of the escalator and its rotation axis are parallel to each other and cleaning the step, and the tip of the rotary lever includes: A rotation limiting member that partially limits the rotation of the roller brush is attached.

Therefore, since only one end of the support arm is fixed to the inner plate of the escalator by the suction device, attachment / detachment of the operation is easy. Also, since the roller brush is attached to the rotary lever that is swingably attached to the other end of the support arm, the elevator ascending operation,
It can be used in any of the descending operations, and while operating the elevator automatically, it is possible to clean the treads and riser surfaces of the steps with a roller brush. Further, since the rotation limiting member attached to the tip of the rotating lever partially limits the rotation of the roller brush, the roller brush rotates so as to sweep the step plate and the riser surface of the step. Therefore, it is possible to reliably sweep out dirt, dust, and the like on the treads and riser surfaces.

(2) In the cleaning tool for steps of an escalator described in (1) above, the rotation limiting member is a friction roller having a rotation support shaft of the roller brush attached to the tip thereof and in close contact with the surface of the step. .

Therefore, at the same time when the roller brush comes into contact with the step plate or the riser surface of the step, the friction roller also comes into close contact with the step plate or the riser surface of the step. Therefore, when the friction roller rotates, friction is generated with each surface of the tread plate and the riser surface, and the rotation of the rotation support shaft attached to the tip of the friction roller is partially restricted. As a result, the rotation of the roller brush is partially restricted, and the roller brush is rotated so as to sweep the step plate and the riser surface of the step. Therefore, it is possible to reliably sweep out dirt, dust, and the like on the treads and riser surfaces.

(3) In the cleaning tool for a step of an escalator described in (1) above, the rotary lever includes two links, and the two links are rotatably connected to each other. A compression spring is provided between the two links, and the rotary lever is bent and restrained.

Therefore, the roller brush is pushed by the movement of the step of the escalator to rotate the link. However, since the rotation of the link is limited by the compression spring, the roller brush is attached to the step plate or the riser surface of the step. It is pressed. For this reason, the roller brush rotates so as to sweep the treads and riser surfaces of the steps, and it is possible to reliably sweep out dirt, dust and the like on the treads and riser surfaces. Further, cleaning can be performed in either operation by changing the bending restraint direction of the rotary lever by the compression spring according to the up and down operation of the escalator.

(4) In the cleaning tool for the step of the escalator described in (3) above, the rotation of the one link is restricted near the rotation fulcrum of the support arm and one link of the rotary lever. A support stopper is provided.

Therefore, since the rotation of one of the links of the rotary lever is limited by the support stopper, the roller brush always contacts the step plate and the riser surface of the step.

At this time, it is confirmed that the support arm 7 is substantially parallel to the front, rear, left and right with respect to the step, and that the surface of the tread plate 1 and the surface of the riser 2 come into contact when the roller brush 10 is swung.

When cleaning both the left and right sides of the footboard 1 and the like at the same time, two stepping cleaning tools 6 of this embodiment and the left and right inner plates 3 of the escalator may be mounted in the same manner as described above. .

Next, the operation of the step cleaning tool 6 of this embodiment will be described with reference to FIG.

When the escalator is in the down operation (in the direction of the arrow "D" in FIG. 4), the roller brush 10 contacts the foot plate 1 of the step moving downward and rotates while cleaning from the front end to the rear end of the foot plate 1. (Solid line display). After that, when the roller brush 10 reaches the rear end of the tread 1, the rotary lever 8 swings (indicated by a dotted line) to clean the riser 2 while contacting the surface of the riser 2. The displacement angle of the rotary lever 8 at the time of cleaning the one step is A (the displacement angle between the solid line display and the dotted line display of the rotary lever 8).

On the other hand, when the escalator is operating upward (in the direction of the arrow "U" in FIG. 4), the rotary lever 8 swings (indicated by a dotted line), and the roller brush 10 hits the riser 2 of the step moving upward. Touch and rotate to clean the riser 2 from the bottom to the top (solid line to dotted line). afterwards,
When the roller brush 10 reaches the surface of the tread 1, the rotary lever 8 stops swinging (indicated by a solid line), and cleans the tread 1 while contacting the surface of the tread 1. The displacement angle of the rotary lever 8 at the time of cleaning this one step is B (the rotary lever 8
The displacement angle between the solid line display and the dotted line display.

According to this embodiment, the installation of the device is simple, and further, the automatic operation of the escalator for both the upward operation and the downward operation can be applied. In particular, it becomes easy to clean the escalator for exclusive use of climbing, which has never been done before.

If a weight is attached to the side of the friction roller 11, the roller brush 10 will not rise.

Second Embodiment. The escalator step cleaning tool of the second embodiment will be described with reference to FIG.
The same components as those of the conventional escalator and the configuration of the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

In the step cleaning tool of the first embodiment, the friction roller 11 is used to partially limit the rotation of the roller brush to clean the surface of the step (illustrated in FIG. 3). As shown in FIG. 5, the step cleaning tool of the present embodiment has a structure in which the rotary lever 8 is divided into two links 15 and 16, and a compression spring is provided between the links 15 and 16 to provide the link 16 The rotation of the roller brush 10 is restricted by the compression spring, so that the roller brush 10 is pressed against the step plate or the riser surface of the step.

That is, as shown in FIG. 5, in the step cleaning tool of this embodiment, the rotary lever 8 of the first embodiment is 2
It consists of links 15 and 16 of the book, and links 15 and 16 are
They are rotatably connected to each other by a link shaft 15a. Further, the compression spring 17 that is engaged between the links 15 and 16
Is provided, and the links 15 and 16 are connected by bending. Therefore, the roller brush is pressed against the step plate or the riser surface of the step. For this reason, the roller brush rotates so as to sweep the treads and riser surfaces of the steps, and it is possible to reliably sweep out dirt, dust and the like on the treads and riser surfaces.

A support stopper 18 for restricting the rotation of the link 15 is provided near the rotation fulcrum of the support arm 7 and the link 15.

Next, the operation of the step cleaning tool of this embodiment will be described with reference to FIG.

When the escalator is in the down operation (in the direction of the arrow "D" in FIG. 5), the roller brush 10 contacts the foot plate 1 of the step moving downward and rotates while cleaning from the front end to the rear end of the foot plate 1. (Solid line display). At this time, link 15
The rotation of is restricted by the support stopper 18. Therefore,
When the roller brush 10 reaches the rear end of the tread plate 1, the link 16 rotates around the link shaft 15a as a fulcrum (indicated by a dotted line) and contacts the surface of the riser 2 to clean the riser 2. The displacement angle of the link 16 at the time of cleaning this one step is C (the displacement angle of the solid line display and the dotted line display of the link 16).

On the other hand, when the escalator is operating upward (in the direction of the arrow "U" in FIG. 5), the rotation of the link 15 is restricted by the support stopper 18, while the roller brush 10 contacts the riser 2 of the step moving upward. Rotate in contact with each other to clean the riser 2 from the lower end to the upper end. At this time, the link 16 rotates about the link shaft 15a as a fulcrum (displayed from a solid line to a dotted line). After that, when the roller brush 10 reaches the surface of the tread 1, the link 16 returns to its original position by the repulsive force of the compression spring 17 (indicated by a solid line), and the tread 1 is cleaned while contacting the surface of the tread 1. The displacement angle of the link 16 at the time of cleaning the one step is F (the displacement angle between the solid line display and the dotted line display of the link 16).

Also in the case of the present embodiment, the link 1 by the compression spring 17 is used in accordance with the up and down operation of the escalator.

When the compression force of the compression spring 17 is increased to increase the bending constraint between the link 15 and the link 16,
The contact pressing force of the tread 1 and the riser 2 of the roller brush 10 is increased. Also in the case of the present embodiment, the left and right steps can be cleaned by a single automatic operation of the escalator by mounting the step cleaning tool of the present embodiment on the left and right inner plates of the escalator.

Third Embodiment. The escalator step cleaning tool of the third embodiment will be described with reference to FIG. 7. still,
The same components as those of the conventional escalator and the configurations of the first and second embodiments described above are designated by the same reference numerals, and the description thereof will be omitted.

The step cleaning tool of the first embodiment has been used in an escalator having an inner plate installed in the vertical direction with respect to the step, but in the step cleaning tool of the present embodiment, the inner plate is inclined. It is used for the escalator provided.

That is, the step cleaning tool of this embodiment is
As shown in FIG. 7, the support arm 19 is formed in a substantially V shape so that the other end of the support arm is parallel to the steps of the escalator. Therefore, even if the inner plate 3 is inclined and attached to the escalator, the rotary lever 8 can be attached to the support arm 19 so as to be perpendicular to the step, and as a result, the rotation shaft of the roller brush 10 and the step are separated. Roller brush 1 is attached to the tip of rotary lever 8 so that it is parallel.
0 can be attached.

[0046]

As described above, according to the step cleaning device for the escalator of the present invention, only one end of the support arm is fixed to the inner plate of the escalator by the suction device.
Easy to attach and detach for operation. Also, when cleaning the step plate and riser surface of the step with the roller brush while automatically operating the escalator, the roller brush is attached to the rotating lever that is swingably attached to the other end of the support arm. It can be used for both uphill driving and downhill driving. Further, the rotation of the roller brush is limited by a rotation limiting member (for example, a friction roller) attached to the tip of the rotary lever, so that the roller brush rotates so as to sweep the step plate and the riser surface of the step. Therefore, it is possible to reliably sweep out dirt, dust, and the like on the treads and riser surfaces. Furthermore, a drive roller for driving the roller is not necessary, and the cleaning tool can be downsized.

Further, the roller brush is pushed by the movement of the step of the escalator to rotate the link, but since the rotation of the link is limited by the compression spring, the roller brush does not contact the step plate or riser surface of the step. It is pressed. For this reason, the roller brush rotates so as to sweep the treads and riser surfaces of the steps, and it is possible to reliably sweep out dirt, dust and the like on the treads and riser surfaces. Further, cleaning can be performed in either operation by changing the bending restraint direction of the rotary lever by the compression spring according to the up and down operation of the escalator.
