Description

  The present invention relates to a cleaning device, and more particularly to a device for cleaning a passage wall surface constituting an escalator.

  The escalator is used by an unspecified number of people, and in order to ensure the safety of the user, as shown in FIGS. 4 and 5, side walls 22 are provided on both sides of the many treads 21, and the side walls 22 are provided. The belt 23 on which the user puts his hand is configured to move at the same speed as the tread plate 21. And the passage wall surface 22a which becomes the tread board 21 side of each side wall 22 touches the user's eyes on the tread board 21, and must always be kept beautiful.

  That is, the tread plate 21, the passage wall surface 22a, and the belt 23 constituting the escalator 20 are easily contaminated by an unspecified number of people or a baggage, and these cleanings are performed regularly or periodically. Must be done manually. As what cleans each part of this escalator 20, various things are proposed by patent documents 1-4, for example.

  In Patent Document 1, for the purpose of “reducing the replacement frequency of a cleaning tool provided in an automatic cleaning device for moving handrails”, as shown in FIGS. An operating means for selectively abutting the moving handrail 2, for example, a cleaning tool moving device 50 is provided, and the cleaning tool 10 is abutted on the moving handrail 2 only for a preset time according to the time required for cleaning the moving handrail 2. "Automatic cleaning device for moving handrails" for "automatic cleaning".

  Patent Document 2 also discloses an “escalator step cleaning tool” for the purpose of “providing an escalator step cleaning tool capable of cleaning a step that has been removed without splashing dust around”. The proposed “escalator step cleaning tool” is composed of a folding frame 10 that forms an enclosure frame and a sheet 12 that covers the frame 10. The frame 10 is formed at both ends thereof. A pedestal 16 that connects the side plates 14 so as to be orthogonal to each other, and a hook that is attached to both ends of each side plate 14 and that is provided at the tip of the support 20 is fitted to a stopper provided on the side plate 14.

If the operation of pressing the cleaning tool against the moving handrail does not occur without operation, the cleaning tool is not updated to a new surface.

Patent Document 4 proposes a “passenger conveyor moving handrail cleaning device” for the purpose of “increasing the cleaning effect of the moving handrail of the passenger conveyor. Also, extending the cleaning period”. In the handrail cleaning device, “When cleaning operation is performed in a cycle, the cleaning tool is updated several times in one cycle depending on the dirt status of the moving handrail by setting the cleaning tool update count and update amount in one cycle. The cleaning effect is improved, and the cleaning amount corresponding to the dirt state of the moving handrail is set by changing the update amount of the cleaning tool in one cycle.
JP-A-5-24782, FIG. 1, FIG. 2, summary JP-A-9-132376, abstract Japanese Patent Laid-Open No. 2001-199670, Abstract JP 2001-261278, abstract

  In the above patent documents, the object of cleaning is “step of escalator” (patent document 2) or “moving handrail” (patent documents 1, 3, and 4), and the tread plate 21 and the belt 23 constituting the escalator 20. However, the passage wall surface 22a of the side wall 22 constituting the escalator 20 cannot be cleaned.

  The passage wall surface 22a in the side wall 22 is a portion that is most easily soiled when touched by the body of the user riding on the tread board 21 or touched by the user's luggage, and is easily touched by the user's eyes. Therefore, for safety, it is a part that must always be cleaned as a corner. The present situation is that the cleaning of the passage wall surface 22a is performed by a cleaning worker holding the cleaning cloth by hand.

  Cleaning of these passage wall surfaces 22a is because the height of the passage wall surface 22a itself is only from the feet to the waist, and each passage wall surface 22a is usually inclined inward toward the feet. It has to bend, it is very painful and takes time. In addition, since the cleaning operation cannot be performed if there is a user, the cleaning operation time is limited, and the cleaning operation of the passage wall surface 22a of the escalator 20 is extremely difficult.

  Accordingly, the inventors of the present invention variously describe how to easily clean the passage wall surface 22a of the side wall 22 constituting the escalator 20 without burdening the operator. As a result of repeated studies, the present invention has been completed.

  That is, an object of the present invention is to efficiently clean the passage wall surface 22a of the side wall 22 constituting the escalator 20, and to be applicable to the escalator 20 in which the dimension between both passage wall surfaces 22a is different. The device 10 is provided by a simple configuration.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
"A device for cleaning the passage wall surface 22a of the side wall 22 rising on both sides of the tread 21 constituting the escalator 20,
A support rod 11 having a handle 11a, a pair of left and right telescopic rods 12 provided so as to be extendable with respect to both ends of the support rod 11, and a mop 13 provided tiltably at the distal ends of the respective extension rods 12. Cleaning device 10 characterized by comprising "
It is.

  That is, the cleaning device 10 according to claim 1 is a device for cleaning the passage wall surface 22a of the side wall 22 rising on both sides of the tread plate 21 constituting the escalator 20, but in FIGS. As shown, a support rod 11 having a handle 11a, a pair of left and right telescopic rods 12 provided to be extendable with respect to both ends of the support rod 11, and provided at the tip of each of the telescopic rods 12 are tiltable. And a mop 13.

  As shown in FIGS. 4 and 5, the cleaning device 10 has the cleaning worker rides on the step board 21 that is raised or lowered with its handle 11a, and applies the mops 13 at both ends to the passage wall surfaces 22a. It is used in contact. At this time, the cleaning worker can perform effective cleaning by moving the cleaning device 10 up and down or left and right while confirming that both mops 13 are in contact with the passage wall surface 22a.

  Here, depending on the escalator 20, the dimension between the passage wall surfaces 22 a may be slightly different. In the cleaning device 10, the extension rods 12 are provided at both ends of the support rod 11 held by the cleaning worker by the handle 11 a. Therefore, the dimension between the mops 13 at both ends may be set in advance according to the passage wall surface 22a of the escalator 20 to be cleaned.

  In the cleaning device 10 according to the best mode, which will be described later, the telescopic rod 12 shown on the right side of FIG. The telescopic rod 12 is inserted and removed so as to correspond to the interval. When the dimension adjustment is completed, the extension rod 12 is fixed to the support rod 11 by inserting a pin into the length adjustment hole 11b formed in the support rod 11 and the corresponding hole on the expansion rod 12 side. You can do that. In the best mode to be described later, a protrusion protruding by a spring is built in the telescopic rod 12 side, and when this protrusion faces the length adjustment hole 11b, it engages with the length adjustment hole 11b. .

  Further, as described above, since the passage wall surface 22a of the escalator 20 is often inclined inward, the dimension between both passage wall surfaces 22a is different between the upper part and the lower part. The dimension between both mops 13 must be changed. However, since the cleaning device 10 does not have to make the support rod 11 perpendicular to the traveling direction of the escalator 20, if it is slightly inclined with respect to the traveling direction, the dimension between the mops 13 is Easy to change. What is important at this time is that each mop 13 is tiltably provided at the tip of each telescopic rod 12.

  If each mop 13 is tiltable with respect to the tip of the telescopic rod 12 as shown by the phantom line shown in the left part of FIG. 2, each mop 13 can freely move according to the inclined state of the passage wall surface 22a. It inclines and the whole cleaning surface contacts the surface of the channel | path wall surface 22a. Therefore, even if the passage wall surface 22a is inclined, the entire cleaning surface of each mop 13 can be expanded and contracted with respect to the support rod 11, and the inclination angle of the entire cleaning device 10 can be freely changed. In addition, the dirt on the passage wall surface 22a can be reliably removed.

  Therefore, the cleaning device 10 according to claim 1 can efficiently clean the passage wall surface 22a of the side wall 22 constituting the escalator 20, and is also applied to the escalator 20 in which the dimension between both passage wall surfaces 22a is different. It can be done.

Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the cleaning apparatus 10 of the said Claim 1,
“At least one of the expansion rods 12 is elastically expanded and contracted with respect to the support rod 11”
It is.

  In the cleaning device 10 according to the second aspect, at least one of the expansion and contraction rods 12 is elastically expanded and contracted with respect to the support rod 11. Specifically, as shown by a dotted line in FIG. 1, the left and right extension rods 12 are accommodated in the support rod 11 so that they can be inserted and removed, and a spring 12 b is provided between the support rod 11 and the extension rod 12. It is intended to be intervened. Of course, in order to allow the telescopic rod 12 to freely expand and contract with respect to the support rod 11, the engagement protrusion 12a provided on the telescopic rod 12 side is engaged with the guide slit 11d formed on the support rod 11 side. In the cleaning operation, the telescopic rod 12 is expanded and contracted with respect to the support rod 11 against the elastic force of the spring 12b, and the rotation can be stopped.

  In the cleaning device 10 of the best mode to be described later, the spring 12b in the support rod 11 is used as a means for allowing the expansion / contraction rod 12 to expand and contract with respect to the support rod 11, but a so-called damper using a pressure fluid is used. It may be implemented using other means. Of course, it goes without saying that the spring 12b may be a compression spring or a tension spring.

  Moreover, although there are a pair of left and right extension rods 12 on both sides of the support rod 11, it goes without saying that at least one of them may be used. This is because the dimension between the wall surfaces 22a of the two passages hardly changes from the top to the bottom of the escalator 20, and the dimensional change of the entire cleaning device 10 is not so much required. This is because it is enough to elastically expand and contract. However, when a powerful person performs the cleaning work, the support rods of both the expansion rods 12 are provided so that the entire cleaning device 10 can be swung many times during one raising and lowering of the escalator 20. It is also effective to make the expansion and contraction with respect to 11 freely.

  In the cleaning device 10 according to claim 2 configured as described above, for example, even if the entire cleaning device 10 is moved up and down, or swung left and right with respect to the traveling direction, the telescopic rod 12 is in relation to the support rod 11. As a result, each mop 13 comes into contact with the surface of the passage wall surface 22a and can be cleaned without leaving any wiping.

  Therefore, the cleaning device 10 according to claim 2 performs the same function as that of the above-mentioned claim 1, and even if it moves to some extent with respect to the passage wall surface 22a, the entire surface of each mop 13 is securely attached to the surface of the passage wall surface 22a. It can be made to come into contact with.

Furthermore, in order to solve the said subject, the means which invention which concerns on Claim 3 took about the cleaning apparatus 10 of the said Claim 1 or Claim 2,
“Each mop 13 is detachably attached to a mop mounting frame 14 that is tiltably provided at the tip of each telescopic rod 12”
It is.

  In other words, the cleaning device 10 according to claim 3 is configured such that the mop mounting frame 14 is tiltably provided at the tip of each telescopic rod 12 and the mop 13 is mounted on the mop mounting frame 14. In this way, the dirty mop 13 can be replaced regardless of the support rod 11 and the expansion rod 12.

  In other words, when the mop 13 is provided directly on the tip of the telescopic rod 12, the soiled mop 13 must be removed from the support rod 11 together with the telescopic rod 12. However, in the cleaning device 10 according to claim 3, the mop 13 Since only 13 can be removed, the main body of the cleaning device 10 can be used as it is, and only the mop 13 can be replaced.

  In the cleaning device 10 of the best mode to be described later, as shown in FIG. 3, the mop mounting frame 14 is tiltably attached to the tip of the telescopic rod 12 by a tilting shaft 14a, and constitutes the mop mounting frame 14. The mop 13 can be attached and detached by the first frame 14b and the second frame 14c. In the mop mounting frame 14, first, the first frame 14b and the second frame 14c constituting the mop mounting frame 14 are formed in a U-shape, and the opened portion is rotatably connected by a single shaft. For example, by using both ends of the open part of the first frame 14b as levers 14d, and by closing these levers 14d, the connection of the first frame 14b to the second frame 14c is released. The mop 13 can be attached.

  Therefore, the cleaning device 10 according to claim 3 can perform the same function as that of claim 1 or 2 and can replace only the mop 13 while leaving the other support rods 11 and the expansion rods 12 as they are. It is.
