Abstract

PROBLEM TO BE SOLVED: To prevent the propagation of various germs and the generation of offensive odors at the treads and risers of an escalator by cleaning the treads and risers with an easily used vacuum cleaner. SOLUTION: An escalator vacuum cleaner 1 is constructed so as to be operated at its handles 9, which fixedly projects from an upper case 4 slantly upward as well as backward and has grip parts 8 at its tip and its middle portion. For cleaning an elevator with the use of the cleaner 1, a rotary brush 2 rotated by the torque of a drive is moved by means of a flexible shaft 15 so as to project at its outer periphery forward from the upper case 4 by a length I longer than the depth (h) of the grooves cut in the treads A of the elevator and also downward from the bottom of a lower case 6 by a length j also longer than the depth (h), to thus rake out dust in the grooves cut in the treads A and risers B of the elevator. The raked dust is sucked through a suction port 5 in the lower case 6 into a dust collector bag arranged in the body of the cleaner 1 by way of a transport pipe.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner for cleaning a step of an escalator, and uses a rotating brush to remove dust lurking in uneven portions of the step, and sucks the extracted dust by a vacuum cleaner. TECHNICAL FIELD The present invention relates to a vacuum cleaner for an escalator that sucks in air and a dust-absorbing device therefor.

[0002]

2. Description of the Related Art The surface of a step of an escalator has an uneven shape having a height of about 1 cm. The shape of the end of the floor board that gets on and off the step is also the same as that of the step, and is arranged so that the concave and convex portions of the floor mesh with each other. Also, the sinking portion connecting the adjacent steps has the same irregular shape as the shape of the floor on which the passenger gets on and off, and is arranged so as to mesh with the end of the step.

[0003] As described above, since the escalator is driven by the operation of the escalator, the dust on the steps of the escalator and the unevenness of the sinking portion is self-cleaned. That is, when the uneven portions of the steps move while meshing with the uneven portions of the floorboard, and when the sinking portion connecting the adjacent steps moves with the end portion of the step as the step moves, each of the meshing portions Dust is removed. Therefore, in most cases, it was neglected as a daily cleaning target, and when cleaning was performed, it was a large-scale thing that was performed by a vendor, including sterilization, washing, etc., but it was made exclusively for this It was not like using a vacuum cleaner.

[Problems to be solved by the invention]

[0004] However, when the gap between the projections and depressions is small, if the gap is small, excessive contact may occur at the engagement portion during operation of the escalator, which may cause abnormal vibration and abnormal noise. An appropriate gap is provided in the meshing portion so that they do not abnormally come into contact with each other. Therefore, various dusts gradually accumulate in this gap.

The dust that gradually accumulates in these gaps comes out of the user's footwear, clothing, personal belongings, etc., and is cleaned by being mixed with fine cotton dust and containing protein components such as dandruff and confectionery waste. If they are neglected for a long time, they may become a source of various germs and off-flavors. For these reasons, the escalator steps have the potential to be one of the danger sites from a sanitary point of view.

However, in general, the place where the escalator is laid is often a large room, and in many cases, the generation of an unpleasant odor which is a danger signal on the sanitary environment is not noticed, and the priority as a cleaning target is low. That is the current situation. For this reason, the escalator is a place that provides a favorable environment for breeding by breeding bacteria which are easy to reproduce according to the seasons of spring, summer, autumn and winter.

SUMMARY OF THE INVENTION The present invention is directed to a vacuum cleaner for an escalator and a dust-absorbing device for the escalator which has been made to solve the above-mentioned problems. It is an object of the present invention to provide a device which can be taken out and cleaned a step and its sinking portion. A second object of the present invention is to provide a device that can efficiently and operably clean dust without scattering dust around the steps and the recesses and depressions of the steps. A third object is to provide an inexpensive device with a simple structure that can efficiently collect dust lurking in the uneven portions of the steps and the sinking portion thereof, and has a simple structure.

[0008] The basic purpose of the above-mentioned object is to take out the device easily and clean the step portion and the sinking portion of the escalator so that the step portion and the sinking portion can be a propagation source of various bacteria. Or, it is no longer the source of off-flavors.
