However, in this case, since the brush having the same width as the step of the passenger conveyor is provided, the entire apparatus becomes large and difficult to transport and accommodate.
In addition, since there are a plurality of types of current step width sizes, there is a problem in that a device suitable for each passenger conveyor must be prepared.

  An object of the present invention is to solve the above-described problems, and the object of the present invention is to facilitate transportation and accommodation by reducing the size of the entire apparatus, and to improve the brush on the step. The present invention provides a passenger conveyor step cleaning device that can clean the entire surface of a step of any width by making the position movable.

  The passenger conveyor step cleaning device according to the present invention is a support that is fixed to a comb plate and extends upward, a screw rod that is rotatably provided on the support, and whose axial direction is orthogonal to the direction of travel of the step, A movable body that is screwed into the screw rod and moves in the axial direction by the rotation of the screw rod, a handle that is provided in the movable body, and that extends in the traveling direction, and is provided at a tip portion of the handle, And a brush in contact with the step.

  According to the passenger conveyor step cleaning device according to the present invention, it is easy to transport and accommodate by reducing the size of the entire device, and for any step of any size by making the position of the brush movable. Can also clean the entire surface.

Embodiment 1 FIG.
1 is a side view of an escalator step cleaning device according to Embodiment 1 of the present invention, FIG. 2 is a front view of a support 2 in FIG. 1, and FIG. 3 is a schematic diagram of a screw rod 4 and a movable body 5 in FIG. FIG. 4 is a side view of the brush 7 and the handle 6 in FIG. 1, and FIG. 5 is an enlarged plan view of the main part of the support 2 in FIG.

  The escalator step cleaning device, which is a passenger conveyor, includes a support body 2 that is fixed to the comb plate 1 and extends upward and has a U-shaped cross section. A screw rod 4 orthogonal to the direction, a moving body 5 that is screwed to the screw rod 4 and moves in the axial direction by the rotation of the screw rod 4, and is fixed to the moving body 5 and extends in the advancing direction of the step 3 A handle 6 and a brush 7 provided at the tip of the handle 6 and in contact with the step 3 are provided.

The support body 2 has a base portion 2a facing the comb plate 1 and a support portion 2b whose both ends extend upward. As shown in FIG. 5, the base 2a is formed with four adjustment holes 2c having a long diameter in the axial direction of the screw rod 4.
A spacer 8 is provided between the comb plate 1 and the support 2 to fill a gap between the comb plate 1 and the support 2.
Fixing holes for fixing the spacer 8 are formed at four locations on the portion of the spacer 8 facing the comb plate 1.
The support 2 is fixed to the comb plate 1 by the fixing screw 9 passing through the adjustment hole 2 c and the fixing hole and screwed to the comb plate 1.
In the support portion 2b, penetrating round holes 10 are formed on the same straight line so as to face each other. Ball bearings 11 are incorporated in the respective round holes 10, and the screw rods 4 are rotatably held on the support 2 via the respective ball bearings 11.

  The movable body 5 is formed with a tubular portion 5a having a cylindrical shape, and a thread groove is formed on the inner surface of the tubular portion 5a. The moving body 5 is screwed with the screw rod 4 by this screw groove. Two fixing screw rods 5b extending radially outward are provided in part of the cylindrical portion 5a.

The handle 6 is formed with two screw holes that pass through the center line of the shaft in a direction perpendicular to the axial direction of the screw rod 4. The fixed screw rod 5b passes through the screw hole, and the handle 6 is fixed to the moving body 5 by tightening the nut 5c from the outside.
A spring (not shown) is provided inside one end of the handle 6, and a scissor 12 biased in the direction in which the spring is closed is attached.
A brush 7 is held by the scissors 12, and the brush 7 is in contact with the step 3.

  A rectangular parallelepiped portion 4 a having a rectangular parallelepiped shape is formed at both ends of the screw rod 4, and protrudes outward of the support 2. Further, one rectangular parallelepiped portion 4a is provided with a handle 13 having a cylindrical portion 13a in which the inside is hollowed out in a square shape so as to be fitted.

  Next, a cleaning procedure using the escalator step cleaning device according to Embodiment 1 will be described.

First, a comb (not shown) is removed from the comb plate 1, and the support 2 is attached to the comb plate 1 with the spacer 8 interposed therebetween.
A screw rod 4 to which the moving body 5 is screwed is attached to the support 2. Furthermore, the handle 6 with the scissors 12 attached to the tip is attached to the moving body 5.
The handle 13 is fitted to either one of the rectangular parallelepiped portions 4 a at the end of the screw rod 4.
Next, the brush 7 is attached to the scissors 12, the brush 7 is brought into contact with the step 3, and then the escalator is operated.
Further, the handle 13 is turned to move the position of the brush 7 on the step 3 to clean the step 3.
When the step 3 is very dirty, the angle of the handle 6 with respect to the step 3 is changed with the screw rod 4 as an axis, and the pressure applied to the step 3 of the brush 7 is adjusted to remove unnecessary matter. .
After turning the handle 13 to clean the step 3 having a width corresponding to the width of the support body 2, the fixing screw 9 is removed from the adjustment hole 2 c, and the support body 2 is moved by the width of the base portion 2 a and adjusted again. A fixing screw 9 is screwed into the hole 2c to fix the cleaning device, and the step 3 is cleaned. At this time, since the adjustment hole 2c is a long hole, the position of the support 2 with respect to the comb plate 1 can be finely adjusted.
When the cleaning device is moved in the direction orthogonal to the traveling direction of the step 3, the brush 7 approaches the end of the step 3, and the handle 13 contacts an obstacle such as an escalator balustrade (not shown). Thereafter, the handle 13 is replaced with a rectangular parallelepiped portion 4 a at the other end of the screw rod 4, and the end of the step 3 is cleaned with the brush 7. As a result, the entire surface of the step 3 having any width can be cleaned.

  As described above, according to the step cleaning device for the escalator according to the first embodiment, it is not necessary to adjust the size of the brush 7 to the width of the step 3, and the step cleaning device can be miniaturized. Is simple. Further, since the brush 7 can be moved in a direction orthogonal to the traveling direction of the step 3, the entire surface of the step 3 having any width can be cleaned.

  Further, since the handle 6 can rotate around the screw rod 4, the angle of the handle 6 with respect to the step 3 can be changed, the pressure of the brush 7 applied to the step 3 can be adjusted, and the step Even if the stain 3 is strong, unnecessary materials can be removed.

  Moreover, since the handle 13 is provided at the end of the screw rod 4, the brush 7 on the step 3 can be easily moved.

  Further, since the handle 13 is detachable from both ends of the screw rod 4, even when the cleaning device approaches the end of the step 3 and the handle 13 comes into contact with an obstacle such as an escalator balustrade, The handle 13 can be replaced with the other end, and the end of the step 3 can be cleaned.

  Moreover, since the brush 7 can be attached or detached from the front-end | tip part of the handle | pattern 6, the brush 7 can be replaced | exchanged easily.

  Further, the base 2a of the support 2 is formed with an adjustment hole 2c having a long diameter and penetrating in a direction perpendicular to the traveling direction of the step 3, so that the support 2 is fixed to the comb plate 1. Can be fine-tuned.

  In the first embodiment having the above-described configuration, an escalator is described as an example of a passenger conveyor. However, the present invention is not limited to this, and may be, for example, a moving sidewalk.

3 is a side view of the escalator step cleaning device according to Embodiment 1. FIG. It is a front view of the support body of FIG. It is a principal part enlarged view of the screw rod of FIG. 1, and a moving body. It is a side view of the brush and handle | steering_wheel of FIG. It is a principal part enlarged plan view of the support body of FIG.
