  The cleaning device disclosed in the above-mentioned document 1 is configured by a brush body that is mounted so as to be sandwiched vertically between a comb and a floor plate that are arranged at entrances and exits where steps enter and exit at both ends of the escalator, and the brush body is fixed for a certain period of time. At the entrance / exit part, it is attached to the side where the step enters, and for a certain period of time, it is attached in the direction in which the step comes out at the entrance / exit part to correct the wrinkles (deformation that flutters in one direction) of the brush hair and stain the step. It is intended to obtain the safety effect of maintaining the aesthetics and the alert color around the steps, and the maintenance effect by extending the life of the brush. However, this conventional brush body is only used for the same product, and the length and hardness of the brush are limited. For example, with a newly installed escalator, the surface is beautiful, and in the step of only adhering dust, which is normal light dirt. Is effective (can remove dust adhering to the step with a brush), but for example, if the escalator is a long-standing existing escalator, and dust adheres to the step surface (especially in the cleat groove) and solidifies and adheres, It was difficult to remove the fixed dust. Here, if the brush is set to short hair and hard material with the intention of removing the sticking dust, the problem is that the surface coating of the step will be peeled off due to strong sliding contact with the step surface where no dust is attached. was there. On the contrary, when the brush is made of long hair and a soft material with priority given to the protection of the surface coating, there is a maintenance problem that the fixed dust cannot be removed and only the brush is damaged. From the above, it has been desired to solve the problems in terms of aesthetics, maintenance of safety functions, and maintenance.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide an escalator cleaning device that is excellent in aesthetics, safety, and maintenance in accordance with the degree of contamination of steps.

  In order to achieve the above object, the present invention provides a step of entering and exiting at the entrance / exit, a floor plate constituting the entrance / exit, and a cleat groove of the step fixed to the tip of the floor plate. In a cleaning device for an escalator comprising a comb having teeth that mesh with each other and a brush body that is slidably contacted with the cleat groove while being mounted between the comb and the floor plate, the cleaning device is a first brush made of short hair and a hard material. And a second brush body made of a soft material with long hair, and the first brush body is mounted for a short period of time to remove fixed dust in the cleat groove, and then the second brush body is The cleaning apparatus for escalators is configured to be attached for a long period of time to remove the adhering dust in the cleat groove.

  According to the structure of the said claim, unlike the method of changing the mounting direction of a brush body with respect to the moving direction of a step like the conventional cleaning apparatus, the cleaning apparatus of this invention is a step (usually existing, A first brush body that slides in contact with an aged escalator and cleans it is attached for a short period of time to remove the adhering dust stuck in the cleat groove, and then a lightly dirty step (cleaned with the first brush body) Or a step of a newly established escalator) is constructed with two types of brush bodies that can be attached to a second brush body that cleans it by sliding (contacting it for a long period of time) and removing attached dust lightly. . Accordingly, it is possible to provide an escalator cleaning device that can remove both fixed dust and adhering dust according to the degree of dirt in the step, and is excellent in aesthetics, safety, and maintenance.

It is a perspective view of the principal part which shows embodiment of this invention. It is sectional drawing which follows the AA line of FIG. It is a single perspective view showing an embodiment of the present invention. It is a single perspective view showing an embodiment of the present invention.

  Hereinafter, the embodiment about the escalator provided with the cleaning device by the present invention is described using FIGS.

  In the figure, the escalator 1 has a balustrade 4 that stands upright on both sides of the step 3 in a state where a large number of steps 3 are connected endlessly from a lower entrance 2 having a width W1 to an upper entrance (not shown). It moves in the direction of arrow Y in FIG. 2 while carrying passengers in synchronization with the handrail 5 provided on the periphery. Here, the entrance / exit 2 is composed of a floor plate 2A which is a strength member and a surface plate 2B which covers the surface of the floor plate 2A, and at the front end portion of this floor plate 2A, a large number of uneven cleat grooves provided on the surface of step 3 A comb 6 having a large number of tooth tips 6 </ b> A meshing with the unevenness with respect to 3 </ b> A is subdivided within the range of the entire width W <b> 2 and fixed to the floor plate 2 </ b> A with screws 7. Further, a thin plate (plate thickness t) fixed body 8A that is mounted so as to be sandwiched between the upper surface of the floor plate 2A and the back surface of the comb 6, and a view of the fixed body 8A and the cleat groove 3A. 2 shows a first brush body 8C having an overall width W2 composed of short-hair and hard material brushes 8B having a length ha (for example, 20 mm) shown in FIG. It is mounted in the mounting state indicated by the solid line 8B. The first brush body 8C is mounted for a short period (for example, one day) to remove the fixed dust K in the cleat groove 3A. The fixed dust K is solidified and fixed by mixing oil in the dust, but after removing this almost or completely to become a step 3 with good appearance, the fixed body 8AA (plate thickness is shown in FIG. 4). The second brush body 8CC composed of the long-haired and soft material brush 8BB having the length hb (for example, 40 mm) and the length hb (for example, 40 mm) is greatly deformed as shown by an imaginary line S in FIG. It has a function of maintaining the beauty of step 3 by wearing it for a long time (for example, always) in the attached state. In this case, the brushes 8B and 8BB are both planted in the fixed bodies 8A and 8AA at the same intervals as the cleat groove 3A. The hard material and the soft material are distinguished from each other by the difference in material or the same material (for example, nylon material). ) But may also be caused by a difference in diameter (thin, thick).

  In short, the cleaning device 8 of the present invention is different in the degree of contamination by using two types of the first brush body 8C and the second brush body 8CC in which the brushes 8B and 8BB having different lengths and hardnesses are planted.
