Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step cleaning body for a passenger conveyor such as an escalator which is a passenger transport machine or an electric road.

[0002]

2. Description of the Related Art Generally, a passenger conveyor such as an escalator has a structure in which a large number of steps are connected endlessly and move between one of the entrances and exits of the other. A plurality of cleat grooves are formed on the upper surface of the steps, and the cleat grooves easily contaminate the mud and dust carried by the passengers.Therefore, an attempt was made to provide a step cleaning body for removing adhering matters at the entrance / exit area. Has been done.

Conventionally, in this type of step cleaning body, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 57-98478, a sliding piece which comes into contact with the cleat groove and the sliding piece are attached to the back surface of the comb. It is proposed to provide a comb plate. In the case where the sliding piece is provided, the cleat groove is cleaned by the sliding piece when the step moves.

[0004]

In such a conventional step cleaning body, since the brush-like sliding piece composed of the needle-like piece is integrally erected on the comb plate which is separate from the comb, When the sliding piece was worn out, it was necessary to discard and replace the integrated product including the comb plate, which was an economic problem. Further, although the sliding piece and the comb plate are adhered to each other, there is a problem in strength reliability.

An object of the present invention is to reduce the cost of a step cleaning body and improve its strength.

[0006]

In order to achieve the above object, the present invention provides a downwardly opening groove on the back surface of a mounting portion of a comb which is mounted on a comb plate of an entrance / exit, and the groove is provided with the above-mentioned comb. Of the brush having a width similar to that of the brush, which is composed of a plurality of needle-shaped pieces arranged in this width, and a step cleaning body composed of a fixed body that grips one end of the brush, are fixed. The tip of one end opposite to the fixed body, which is the other end, is brought into contact with the cleat groove for cleaning.

Further, the fixed body is substantially C-shaped, and the brush is projected from the opening of the fixed body while the brush is held inside the C-shaped body. Further, the groove on the back surface of the attachment portion of the comb is C-shaped. The outer shapes are engaged with each other, and the comb and the fixed body are moved in the width direction of each other to be attached and detached.

[0008]

According to the present invention, the brush is fixed by the substantially C-shaped fixed body which holds one end of the brush as described above, and the engagement with the comb is combined with the groove on the back surface of the comb whose outer shape is substantially C-shaped. Since it can be detached by moving laterally, the fixed relationship between the brush and the fixed body is reliable, and a large comb plate as in the conventional case is not required, which is economical.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, 1 indicates one of the entrances and exits,
2 and 2a are steps that move between another entrance (not shown) on the opposite side of the entrance / exit 1, and 3 and 3a are cleat grooves of uneven cleats formed on the upper surfaces of the steps 2 and 2a. Four
Is a comb plate that is a fixed body that constitutes the entrance / exit 1 and the like,
5 is fixed to the tip of the comb plate 4 with screws 5a,
Tip portion 5b and mounting portion 5c that mesh with cleat grooves 3 and 3a
Comb consisting of. Further, 5d is a groove having an opening 5dd and formed in a substantially C shape, and as shown in the drawing, the opening 5dd is opened toward the cleat grooves 3 and 3a. Further, as shown in FIG. 2, the step cleaning body 6 is composed of a brush 6a composed of a needle-shaped piece and a substantially C-shaped fixed body 6b, and the brush 6a is firmly gripped in the C-shape. . The fixed body 6b is preferably formed of a metal plate and is mechanically gripped so as to wrap the one end 6A of the brush 6a, not by adhesion.

The C-shaped outer shape of the step cleaning body 6 is engaged with and integrated with the groove 5d on the inner circumference. The lateral width of the comb 5 (not shown) and the width of the step cleaning body 6 are integrated. Are of the same size and can be attached and detached by laterally moving along the groove 5d in the width direction of the comb 5 when the screw 5a is removed, which are integrally engaged in the mounted state of FIG.

[0012]

According to the present invention, it is possible to provide a step cleaning body for a passenger conveyor, which is excellent in cost and joint strength.
