CONSTITUTION:A cleaning tool 2 coming into contact with an escalator footstep 1 is held on one end of a support arm 3 whose other end is rotatably supported with a fixing member, and an arm restraining device 8 is arranged on the fixing member so as to restrain the movement of the support arm 3 in order to prevent a springing-up phenomenon of the cleaning tool 2 on a riser surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for cleaning escalator steps, especially cleat surfaces.

[0002]

2. Description of the Related Art A conventional cleaning device for cleaning an escalator step is constructed as described in JP-A-57-18578, which is shown in FIG. That is, the cleaning tool 2 abutting on the step 1 is supported on one end of the substantially arcuate support arm 3, and the other end of the support arm 3 is freely rotatable by the support rod 6 to the mounting member 5 fixed to the deck cover portion 4 of the escalator. And the spring 7 so that the cleaning tool 2 follows the cleat surface 1a on which the passenger stands.
The support arm 3 is configured to have a rotational force applied thereto.

[0003]

In the conventional escalator step cleaning device configured as described above, the step 1 was cleaned while the step 1 was moved. When the step 1 is moved in the direction of the arrow 1e shown in FIG. 12, the cleaning tool 2 jumps upward when passing the upper end 1c of the riser surface 1b, and moves along the locus shown by the broken line 2c. It was found that the jumping phenomenon occurred. That is, the cleaning tool 2 bounces from the state shown in FIG. 12 by colliding with the cleat surface 1a as shown in FIG. 13, and in the bounced state as shown in FIG.
b, then bouncing converges and riser surface 1b
To move along. Therefore, the portion of the riser surface 1b that can be cleaned is only the shaded portion 2d shown in FIG. 15 which is a front view, and the entire area of the riser surface 1b cannot be cleaned.

An object of the present invention is to provide an escalator step cleaning device capable of cleaning the entire riser surface by preventing a rising phenomenon on the riser surface.

[0005]

In order to achieve the above object, the present invention rotatably supports the other end of a support arm, which has a cleaning tool abutting against a riser surface of an escalator step, at one end thereof to a fixing member. In the cleaning device for the escalator stairs, the arm restraining device for restraining the movement of the support arm is provided on the fixing member so as to prevent the cleaning tool from jumping up on the riser surface.

[0006]

The cleaning device for the escalator steps according to the present invention is
Since the arm restraint device for restraining the jumping-up phenomenon is provided as described above, the arm restraint device always restrains the cleaning tool on the riser surface of the step, so that the cleaning tool reliably and uniformly cleans the entire riser surface. You can

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of an elevator step cleaning device according to an embodiment of the present invention. A cleaning tool 2 for cleaning a cleat surface 1a and a riser surface 1b on which a passenger of a step 1 stands is provided with a substantially arcuate support arm 3. By fixing the mounting member 5 to an appropriate fixing member such as the deck cover 4 of the escalator, which is supported at one end,
The other end of the support arm 3 is rotatably supported by a support rod 6 that is rotatably supported by the mounting member 5, and the mounting member 5 near the other rotatable end of the support arm 3 has the support arm 3 of An arm restraint device 8 that is located on the bounce side and suppresses the bounce phenomenon of the support arm 3 is attached so as to keep the cleaning tool 2 pressed against the cleat surface 1a. This arm restraint device 8 is an air dashpot device,
An oil dashpot device or a rubber such as sorbolein having a very small coefficient of restitution is used to form a shock absorber that suppresses movement without repulsing an applied force.

Now, when trying to clean the escalator steps, the cleaning tool 2 is arranged on the steps 1 as shown in FIG. 2, and the steps 1 are moved in the direction of the arrow 1e. When the cleaning tool 2 passes over the upper end portion 1c of the riser surface 1b, the cleaning tool 2
However, the cleaning tool 2 slides on the cleat surface 1a of the step 1 along the broken line 2a as shown in FIG. After that, the cleaning tool 2 is attached to the riser surface 1 as shown in FIG.
The lower end 1d of b continues to be in contact, and as shown by the broken line 2a, the entire riser surface 1b is slid and cleaned.

FIG. 5 is a partial side view of an elevator step cleaning device according to another embodiment of the present invention. In the cleaning device for the elevator steps in this embodiment, a shock absorbing device 2d is additionally attached between the support arm 3 and the cleaning tool 2,
The impact absorbing device 2d is also made of rubber such as an air dashpot device, an oil dashpot device, or sorbolein having a very small coefficient of restitution, like the arm restraining device 8, and after the cleaning tool 2 slides on the cleat surface 1a, the riser This is to alleviate the impact when it collides with the surface 1b. When the cleaning tool 2 comes into contact with the riser surface 1b, as shown in FIG.
Although the tip end of the moving member moves in the opposite direction of the mounting member 5 and rotates in the direction of the arrow 1f, the shock absorbing device 2d absorbs the force in the direction of the arrow 1f, so the shock when the riser surface 1b and the cleaning tool 2 come into contact is mitigated. To be done. As a result, the cleaning tool 2 is moved to the riser surface 1
Bounce due to reaction when colliding with b can be prevented,
The riser surface can be cleaned with higher performance.

FIG. 7 is a side view of an escalator step cleaning device according to still another embodiment of the present invention. In the elevator step cleaning device of this embodiment, the mounting member 5 is used.
The arm suppressing device 8 attached to the support arm 3 is attached not to the rising side of the support arm 3 but to the falling side. FIG. 8 shows an intermediate state of the operation. When the step 1 is moved in the direction of the arrow 1e, the riser surface 1b
Although the cleaning tool 2 that has passed over the upper end portion 1c of the cleaning tool jumps upward, the speed of the cleaning tool 2 moving downward is suppressed to prevent the cleaning tool 2 from colliding with the cleat surface 1a, and the broken line 2
It can be moved along the locus shown in b. Further, the support arm 3 which has been rotated clockwise by its own weight moves from the state shown in FIG. 9 to the state shown in FIG. 10 while being prevented from jumping up by the arm restraint device 8, and therefore moves along the locus shown by the broken line 2b. Reach surface 1b. Therefore, the riser surface 1b
The cleaning tool 2 makes contact without bouncing at the lower end 1d, and the entire riser surface 1b can be cleaned.

The movable portion of the arm restraint device 8 may be connected to the support arm 3 to restrain the jumping phenomenon of the cleaning tool 2.

[0012]

As described above, in the cleaning device for the escalator step according to the present invention, the supporting arm is provided with the arm suppressing device so as to suppress the phenomenon that the cleaning tool jumps up on the cleat surface. The riser surface can be contacted from the lower end portion, and the entire riser surface can be uniformly cleaned.
