Description

Technical Field

[0001] This invention relates to a cleaning tool for escalators used for cleaning the steps of escalators. Background Technology

[0002] Previously, a cleaning tool for escalator steps was known (see Patent Document 1).

[0003] like Figure 17 As shown, the escalator steps are fixed to the inner side plate 19 of the escalator via a suction device 12, with the support arm 11 of the cleaning tool 10 parallel to the escalator steps 16. The suction device is installed at one end of the support arm 11. A rotating rod 13 is oscillatingly mounted at the other end of the support arm 11, with a pivot axis 14 as the fulcrum. Furthermore, a roller cleaning brush 15 for cleaning the steps 16 is rotatably mounted at the front end of the rotating rod 13, and the rotation axis of the roller cleaning brush 15 is parallel to the escalator steps 16.

[0004] The aforementioned escalator steps are cleaned using cleaning tool 10, when the escalator is running downwards ( Figure 18 (In the direction of arrow "D"), the roller cleaning brush 15 abuts against and rotates against the pedal 17 of the descending step 16, simultaneously cleaning from the front end to the rear end of the pedal 17 (indicated by solid lines). Then, after the roller cleaning brush 15 reaches the rear end of the pedal 17, the rotating rod 13 swings (indicated by double-dotted lines), thereby abutting against the surface of the kick plate 18 and cleaning the kick plate 18.

[0005] On the other hand, when the escalator is operating upwards ( Figure 18 As the rotating rod 13 swings (indicated by the double-dotted line), the roller cleaning brush 15 abuts against and rotates against the pedal 17 of the upward-moving step 16, thereby cleaning from the rear end to the front end of the pedal 17 (indicated by the transition from the solid line to the double-dotted line). Then, after the roller cleaning brush 15 reaches the front end of the pedal 17, it swings to abut against the next (downstream) pedal 17 (indicated by the solid line), thereby abutting against the surface of that pedal 17 and simultaneously cleaning that pedal 17.

[0006] Existing technical documents Patent Document 1: Japanese Patent Application Publication No. 9-278339 Summary of the Invention The technical problem that the invention aims to solve The step cleaning tool 10 for escalators described above is capable of cleaning the steps 16 regardless of whether the escalator is in up operation or down operation, but if the operation direction of the escalator is switched during cleaning, the drum cleaning brush 15 will collide with the steps 16 and the boundary portions of the steps 16 and the like, resulting in a force in the direction of compression being applied to the rotating rod 13, which can cause damage to the rotating rod 13 or detachment of the suction device 12 from the inner side plate 19 and the like, so the operation direction of the escalator cannot be switched during cleaning.

[0007] Therefore, an object of the present application is to provide a step cleaning tool for escalators capable of switching the operation direction of the escalator during cleaning.

[0008] Solution for solving the technical problem The step cleaning tool for escalators of the present application has: a support portion detachably attached to an inner side plate of an escalator; a brush portion that cleans the steps of the escalator; a rotating portion that rotates with respect to the support portion about a rotating shaft extending in the width direction of the steps; The rotating portion connects the support portion and the brush portion in such a manner that the interval between the rotating shaft and the brush portion is freely increased or decreased within a range where the interval is equal to or less than a predetermined interval, as viewed from the direction in which the rotating shaft extends.

[0009] According to this structure, the rotating portion connects the support portion and the brush portion in such a manner that the interval between the rotating shaft and the brush portion is freely increased or decreased within a range where the interval is equal to or less than a predetermined interval, so even if the operation direction of the escalator is switched, collision of the brush portion does not occur, and thus the operation direction can be switched during cleaning.

[0010] In the step cleaning tool for escalators, it is also possible that: a pair of the support portions are provided at intervals in the direction in which the rotating shaft extends.

[0011] According to this structure, since there are two (a pair of) portions attached to the inner side plate and supporting the brush portion and the like, the weight of the brush portion and the like can be more sufficiently supported.

[0012] In addition, in the step cleaning tool for escalators, it is also possible that: the rotating portion has an extension portion that extends at least from the support portion to the brush portion, as viewed from the direction in which the rotating shaft extends, the brush portion has a pair of cleaning brushes disposed on one side and the other side of the front end portion of the extension portion in directions orthogonal to the direction in which the extension portion extends and the direction in which the rotating shaft extends, respectively.

[0013] Thus, since the brush portion has a pair of cleaning brushes (i.e., a cleaning brush that cleans the steps when the escalator is running in the upward direction, and a cleaning brush that cleans the steps when the escalator is running in the downward direction), the steps can be cleaned appropriately regardless of the direction in which the escalator is running.

[0014] In addition, in the escalator cleaning tool, the brush portion can further include, the brush portion has a wheel that has the extension direction of the rotation shaft as a rotation center, the wheel is disposed so as to project toward the extension direction of the extension portion with respect to each cleaning brush between the pair of cleaning brushes.

[0015] According to this structure, when the running direction of the escalator is switched during cleaning and the turning portion is turned, the member or the portion located between the cleaning brushes can be prevented from coming into contact with the steps, and thus the turning portion can be smoothly turned.

[0016] Effects of the Invention Based on the above, according to the present application, an escalator cleaning tool that can switch the running direction of the escalator during cleaning can be provided. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0040] Hereinafter, referring to Figures 1-7 a first embodiment of the present application will be described.

[0041] As shown in Figures 1-5A , the escalator cleaning tool 1 of the first embodiment has: a support portion 2 which can be fixed to an inner side plate 101 of an escalator 100; a brush portion 4 which cleans a step 110 of the escalator 100; and a turning portion 3 which connects the support portion 2 and the brush portion 4.

[0042] The support portion 2 has: a support portion main body 21; a mounting portion 22 which is arranged on the support portion main body 21; and a rotation shaft 23 which extends from the support portion main body 21. The support portion 2 of the present embodiment has a plurality of (two in the example shown in Figure 1 ).

[0043] The support portion main body 21 is a portion or a member in which the two mounting portions 22 and the rotation shaft 23 are arranged. The support portion main body 21 of the present embodiment extends in a depth direction of a step plate (step) 111 (hereinafter, simply referred to as "depth direction of the step plate 111") in a state in which the escalator cleaning tool 1 is arranged on the escalator 100 (refer to Figure 5A), and mounting portions 22 are arranged at both end portions of the support portion main body 21. Further, in the example shown in the figure, the support portion main body 21 extends in a direction inclined with respect to the depth direction. Figure 5A

[0044] The plurality of mounting portions 22 are portions or members that are mounted to the inner side plate 101 of the escalator 100 in a detachable manner, respectively. These plurality of mounting portions 22 are mounted to the inner side plate 101, whereby the support portion 2 is fixed to the inner side plate 101 in a state of supporting the rotating portion 3 and the brush portion 4.

[0045] The mounting portion 22 of the present embodiment is a suction cup, and is mounted to the inner side plate 101 by suction. Further, the manner in which the mounting portion 22 is mounted to the inner side plate 101 is not limited to suction, and can also be magnetic attraction, clamping, or the like. That is, the mounting portion 22 is a structure that is mounted to the inner side plate 101 in a detachable manner.

[0046] In a state in which the escalator cleaning tool 1 is arranged at the escalator 100, the rotation shaft 23 extends from the support portion main body 21 in the width direction of the step 110 (hereinafter, also simply referred to as "the width direction of the step 110"). The rotation shaft 23 of the present embodiment is a portion in a cylindrical shape that extends in the width direction of the step 110. The rotation shaft 23 of the present embodiment is fixed to the support portion main body 21 by a bracket B or the like.

[0047] The rotating portion 3 is rotatable about the rotation shaft 23. When viewed from the direction in which the rotation shaft 23 extends (hereinafter, also referred to as the "rotation shaft direction"), this rotating portion 3 is connected to the brush portion 4 in a manner in which the rotation shaft 23 and the brush portion 4 are separated by a separation distance α1 (refer to FIG. 1) that is freely increased or decreased within a range of a maximum separation distance (predetermined separation distance) α Figure 1 Figure 4 ). max (Refer to FIG. 1). Figure 5A

[0048] Specifically, the rotating portion 3 has a stem portion (extension portion) 31 that extends at least from the support portion 2 to the brush portion 4 when viewed from the rotation shaft direction, and a rotation engaging portion 32 that rotatably connects the stem portion 31 to the support portion 2. The rotating portion 3 of the present embodiment has one stem portion 31. In addition, the rotating portion 3 has a stopper 33 arranged at the stem portion 31. In addition, the rotating portion 3 has a rotating portion wheel 34 arranged at the stem portion 31.

[0049] ​​​The stem portion 31 is a portion that extends straight in a direction connecting the support portion 2 (in detail, the rotation shaft 23) and the brush portion 4 when viewed in the rotation shaft direction. The stem portion 31 of the present embodiment is longer than the interval between the support portion 2 (the rotation shaft 23) and the brush portion 4 when viewed in the rotation shaft direction. The stem portion 31 has a guide groove 311 at each of the both ends in the rotation shaft direction, which is recessed toward the inner side in the rotation shaft direction and extends in the extending direction of the stem portion 31 (hereinafter, also referred to as "stem direction"). That is, the stem portion 31 has a pair of the guide grooves 311.

[0050] The rotation engaging portion 32 holds the stem portion 31 so as to be movable (reciprocable) in the stem direction, and engages with the rotation shaft 23 so as to be freely rotatable around the rotation shaft 23. The rotation engaging portion 32 of the present embodiment holds the stem portion 31 so as to be slidable in the stem direction by engaging with each of the guide grooves 311 of the stem portion 31.

[0051] When the stem portion 31 slides (moves) toward the brush portion 4 (the front end side) with respect to the rotation engaging portion 32, the stopper 33 can stop the stem portion 31 from further sliding (moving) toward the brush portion 4 by abutting against the rotation engaging portion 32. The stopper 33 is provided at the end portion of the stem portion 31 on the side farther from the brush portion 4. The stopper 33 of the present embodiment protrudes outward in the circumferential surface of the stem portion 31 and extends in the circumferential direction.

[0052] When the stopper 33 abuts against the rotation engaging portion 32, the interval a1 between the support portion 2 (the rotation shaft 23) and the brush portion 4 is the largest, and the interval between the support portion 2 (the rotation shaft 23) and the brush portion 4 at this time is the maximum interval a1. max That is, the stopper 33 is a portion or a member that defines the maximum value of the interval a1 that can be increased or decreased.

[0053] The rotation portion wheel 34 is a wheel that can rotate around a rotation center axis C1 extending in the rotation shaft direction, and is provided at the end portion of the stem portion 31 on the side close to the brush portion 4. The rotation portion 3 of the present embodiment has a plurality of (two in the example) rotation portion wheels 34 arranged in parallel in the stem direction. Figure 1

[0054] The brush portion 4 has a cleaning brush 41 and a cleaning brush holding portion 42 that holds the cleaning brush 41. In addition, the brush portion 4 has a brush portion wheel (wheel) 43. The brush portion 4 of the present embodiment has a pair of the cleaning brushes 41. In addition, the brush portion 4 of the present embodiment has a pair of the brush portion wheels 43.

[0055] In each of the cleaning brushes 41, the cleaning brush bristles extend in a direction orthogonal to both the stem direction and the rotation shaft direction (hereinafter, also referred to as "orthogonal direction"), and are arranged in the rotation shaft direction.

[0056] ​The cleaning brush holding portion 42 extends in the rotation axis direction and is connected to the lower end portion (front end portion) of the rod portion 31. In the cleaning brush holding portion 42 of the present embodiment, the end portion on one side in the rotation axis direction is connected to the lower end portion (front end portion) of the rod portion 31. On the cleaning brush holding portion 42, the cleaning brush 41 is arranged on each of the end portions on the one side and the other side in the orthogonal direction. Thus, the pair of cleaning brushes 41 is arranged on the one side and the other side of the lower end portion of the rod portion 31 in the orthogonal direction.

[0057] The pair of brush portion wheels 43 is arranged on the end portion on one side and the end portion on the other side of the cleaning brush holding portion 42 in the rotation axis direction. Each brush portion wheel 43 is a wheel that is rotatable about a rotation center axis C2 extending in the rotation axis direction, and is arranged on the cleaning brush holding portion 42 in such a manner as to protrude toward the rod direction (the direction from the upper end toward the lower end of the rod portion 31) with respect to each cleaning brush 41.

[0058] Next, the operation of the escalator cleaning tool 1 of the present embodiment will be described with reference to Figures 5B-7 The operation of the escalator cleaning tool 1 of the present embodiment will be described with reference to

[0059] When the escalator 100 is in a stopped state, the support portion 2 (in detail, each mounting portion 22) of the escalator cleaning tool 1 is mounted (sucked) to the inner side plate 101.

[0060] Next, the escalator 100 starts to operate. For example, as shown in FIG. 6, in the case where the escalator 100 is in a downward operation, in a state where the one-side cleaning brush 41 is in abutment with the tread 111 of the step 110 moving downward, the cleaning brush 41 cleans from the front end toward the rear end of the tread 111 (see FIGS. 7 and 8). Figure 5A Figure 5A Figure 5B At this time, as viewed in the rotation axis direction, the rod portion 31 is inclined with respect to the vertical imaginary line L1 in such a manner that the lower end portion of the rod portion 31 is located on the downstream side of the moving direction of the step 110 (on the downward moving direction side of the step 110) with respect to the vertical imaginary line L1 passing through the rotation axis 23.

[0061] Then, after the one-side cleaning brush 41 reaches the rear end of the tread 111, in a state where the rod portion 31 is turned in a direction in which the lower end portion of the rod portion 31 is separated from the vertical imaginary line L1 and the one-side cleaning brush 41 is in abutment with the kick plate 112, the cleaning brush 41 cleans from the lower end toward the upper end of the kick plate 112 (see FIGS. 9 and 10). Figure 6A Figure 6B

[0062] During the cleaning of the kick plate 112 from the lower end toward the upper end, in the case where the turning portion wheel 34 comes into contact with the kick plate 112, the turning portion wheel 34 rotates. Thus, the rod portion 31 is prevented from coming into contact with the step 110, and as a result, the cleaning of the kick plate 112 can be performed smoothly on the site.​​​​

[0063] During the continuous downward movement of the escalator, the cleaning brush 41 on this side alternately and repeatedly cleans from the front end to the rear end of the step 111 and from the lower end to the upper end of the kick plate 112.

[0064] After a specified period of downward movement, if the escalator 100 is switched to upward movement (i.e., switched to upward movement), the movement direction of each step 110 will be reversed.

[0065] As the step 110 moves upward, the brush part 4, which is in contact with the pedal 111, moves together with the step 110 in the upward direction (see reference). Figure 7 The rotating part 3 and brush part 4 of the solid line). At this time, as the step 110 moves upward, the rod part 31 rotates with its lower end facing the upward movement direction. Moreover, viewed from the direction of the rotation axis, the rod part 31 moves relative to the rotating engagement part 32 (rotation axis 23) in the direction where the distance α1 between the support part 2 (more specifically, the rotation axis 23) and the brush part 4 decreases (see reference). Figure 7 The arrow β1) slides.

[0066] Furthermore, as the rod 31 crosses the vertical imaginary line L1 from the upstream side to the downstream side, the brush wheel 43 contacts the pedal 111 and thereby rotates on the pedal 111.

[0067] If the rod 31 continues to rotate, the sliding direction of the rod 31 relative to the rotating engagement part 32 reverses. That is, while the rod 31 rotates around the rotation axis 23, the rod 31 relative to the rotating engagement part 32 (rotation axis 23) begins to move in the direction where the distance α1 between the support part 2 (rotation axis 23) and the brush part 4 increases (see reference). Figure 7 The arrow β2) slides.

[0068] The lever 31 rotates fully and slides fully until the stop 33 abuts against the rotating engagement part 32 (see reference). Figure 7 After the double-dotted rotating part 3 and brush part 4 are connected, the sliding of the rod part 31 is stopped (i.e., the sliding stops), and the pedal 111 is cleaned by the cleaning brush 41 on the other side.

[0069] Specifically, with the cleaning brush 41 on the other side abutting against the pedal 111 of the upward-moving step 110, the cleaning brush 41 cleans the pedal 111 towards its front end (see reference). Figure 7 The rotating part 3 and brush part 4 of the double-dotted line). At this time, when viewed from the direction of the rotation axis, the rod part 31 is inclined relative to the vertical imaginary line L1 such that the lower end of the rod part 31 is located on the downstream side of the moving direction of the step 110 (the side of the upward moving direction of the step 110) relative to the vertical imaginary line L1.

[0070] Then, after the other-side cleaning brush 41 reaches the front end of the step 111, the rod portion 31 is turned toward the direction in which the lower end portion of the rod portion 31 approaches the vertical imaginary line Ll, and the other-side cleaning brush 41 falls down to the step 110 (the step 110 adjacent to the step 110 on the descending direction side) next to the step 111. At this time, as viewed from the direction of the rotation axis, the rod portion 31 is also inclined with respect to the vertical imaginary line Ll in such a manner that the lower end of the rod portion 31 is located on the downstream side of the step 110 in the moving direction with respect to the vertical imaginary line Ll.

[0071] The cleaning brush 41 fallen down to the step 111 next to the step 111 performs cleaning from the fallen position of the cleaning brush 41 to the front end in the state of abutting against the step 111.

[0072] The cleaning from the fallen position to the front end of the cleaning brush 41 is repeatedly performed for each step 111 by the other-side cleaning brush 41 during the continuous ascending operation of the escalator 100.

[0073] Thus, in the process of cleaning the escalator 100 by the escalator cleaning tool 1, when the escalator 100 is switched from the descending operation to the ascending operation, the escalator cleaning tool 1 operates as described above, and when the escalator 100 is switched from the ascending operation to the descending operation in the process of cleaning, the escalator cleaning tool 1 operates in the reverse direction of the operation described above.

[0074] The above escalator cleaning tool 1 has: a support portion 2 mounted to the inner side plate 101 of the escalator 100 in a detachable manner; a brush portion 4 for cleaning the steps 110 of the escalator 100; and a rotation portion 3 rotatable with respect to the support portion 2 about a rotation axis 23 extending in the width direction of the steps 110. Further, the rotation portion 3 is arranged so that the interval a1 between the rotation axis 23 and the brush portion 4 is the maximum interval (predetermined interval) a max The support portion 2 and the brush portion 4 are connected in a freely variable manner within the above range.

[0075] With this structure, since the rotation portion 3 is arranged so that the interval a1 between the rotation axis 23 and the brush portion 4 is the maximum interval a max The support portion 2 and the brush portion 4 are connected in a freely variable manner within the above range, and thus, even when the operation direction of the escalator 100 is switched, the collision of the brush portion 4 does not occur, and thus, the operation direction can be switched in the process of cleaning.

[0076] In addition, in the escalator cleaning tool 1 of the first embodiment, the rotating part 3 has a rod part (extension part) 31 that extends from the support part 2 to the brush part 4, and the brush part 4 has a pair of cleaning brushes 41, which are respectively arranged on one side and the other side of the lower end (front end) of the rod part 31 in a direction orthogonal to the rod direction (the extension direction of the rod part 31) and the rotation axis direction (the extension direction of the rotation axis 23).

[0077] Thus, since the brush section 4 has a pair of cleaning brushes 41 (i.e., cleaning brushes 41 that clean the steps 110 when the escalator 100 is moving upwards and cleaning brushes 41 that clean the steps 110 when it is moving downwards), the steps 110 can be cleaned appropriately regardless of which direction the escalator is moving in.

[0078] In addition, in the escalator cleaning tool 1 of the first embodiment, the brush part 4 has a brush part wheel (wheel) 43 with the rotation axis direction (the extension direction of the rotation axis 23) as the rotation center. The brush part wheel 43 is arranged in such a way that it protrudes between a pair of cleaning brushes 41 relative to each cleaning brush 41 in the extension direction of the rod part (extension part) 31.

[0079] Therefore, when the escalator 100 is switched to a different direction of operation during cleaning, causing the rotating part 3 to rotate, the cleaning brush holding part (a component or part located between the cleaning brushes 41) 42 can be prevented from contacting the step 110. As a result, the rotating part 3 can rotate smoothly. In addition, by preventing such contact, damage to the step 110 caused by contact with the cleaning brush holding part 42 can also be prevented.

[0080] Next, refer to Figures 8-16 The second embodiment of the present invention will be described below. The same reference numerals are used for structures that are the same as those in the first embodiment described above, and detailed descriptions are omitted. Only the different structures will be described in detail.

[0081] like Figures 8-11 As shown, the escalator cleaning tool 1A of the second embodiment includes: a support portion 2A, a brush portion 4A, and a rotating portion 3A. The escalator cleaning tool 1A of this embodiment includes a pair of support portions 2A.

[0082] Each pair of support portions 2A has: a support portion body 21A; and multiple ( Figure 8 (In this example, there are four) Mounting part 22. Additionally, each pair of support parts 2A has a rotating engaging part 25 disposed on the support part body 21A. With the escalator cleaning tool 1A disposed on the escalator 100, this pair of support parts 2A are spaced apart in the width direction of the tread 111 (see reference). Figure 14A). Specifically, in a state where the escalator cleaning tool 1A is arranged at the escalator 100, the one-side support portion 2A is attached to the one-side inner side plate 101, and the other-side support portion 2A is attached to the other-side inner side plate 101.

[0083] The support portion main body 21A is a site or a member where four attachment portions 22 and a rotation engaging portion 25 are arranged. The support portion main body 21A of the present embodiment has a plurality of (two in the example shown) first sites 211 extending in the depth direction of the step 111, and a second site 212 connecting the first sites 211 to each other. Further, in the example shown, the first sites 211 extend in a direction inclined with respect to the depth direction. Figure 1 Figure 14A In the example shown, the first sites 211 extend in a direction inclined with respect to the depth direction.

[0084] The attachment portions 22 are arranged at both end portions of each first site 211, and the two first sites 211 are arranged at intervals in the vertical direction in a state where the support portion 2A is attached to the inner side plate 101 (refer to FIG. 2). Figure 14A

[0085] The second site 212 extends in the vertical direction in a state where the support portion 2A is attached to the inner side plate 101, and the first sites 211 are respectively connected to both end portions of the second site 212. The second site 212 of the present embodiment is a site in the form of a plate that expands along the inner side plate 101 in a state where the support portion 2A is attached to the inner side plate 101, and has an attached portion 212a where the rotation engaging portion 25 is attached at a lower end portion.

[0086] The rotation engaging portion 25 supports the rotation portion 3A rotatably by engaging with a portion (rotation shaft 35 described later) of the rotation portion 3A.

[0087] The rotation portion 3A has a base portion 30, a plurality of rod portions (extension portions) 31 arranged at the base portion 30, and a stopper 33 arranged at at least one rod portion 31. Further, the rotation portion 3A has a pair of rotation shafts 35 respectively extending from the base portion 30. In a state where the escalator cleaning tool 1A is arranged at the escalator 100, the pair of rotation shafts 35 respectively extend in the width direction of the step 111 (hereinafter, also referred to as "rotation shaft direction").

[0088] The base portion 30 has a base portion main body 301 extending in the rotation shaft direction, a cylindrical guide cylinder 302, and a shaft support portion 303 supporting the rotation shaft 35.

[0089] The base portion main body 301 extends in the rotation shaft direction from the one-side support portion 2A to the other-side support portion 2A. As shown in FIG. 2, for example, the base portion main body 301 has a plurality of (two in the example shown) first sites 311 extending in the rotation shaft direction. Figure 12 Figure 13 The base portion main body 301 has a plurality of (two in the example shown) first sites 311 extending in the rotation shaft direction. Figure 9 ​​​The example shown is three) through holes 301a.

[0090] The plurality of through holes 301a each penetrate the base body 301 in the same direction and are arranged at intervals in the base body 301 in the direction of the rotation axis.

[0091] The guide cylinder 302 is a cylindrical portion extending in the penetration direction of the through hole 301a and is arranged in the base body 301 so as to communicate with the hollow portion S and the through hole 301a. In the rotating portion 3A of the present embodiment, the guide cylinder 302 is arranged in the base body 301 at the position of the through hole 301a at the one end portion and the position of the through hole 301a at the other end portion in the plurality of through holes 301a arranged in the direction of the rotation axis. That is, the base 30 of the present embodiment has two guide cylinders 302.

[0092] The shaft support portion 303 extends from both end portions of the base body 301 in the penetration direction of the through hole 301a, respectively. That is, the base 30 has a pair of shaft support portions 303. The shaft support portion 303 of the present embodiment is a plate shape that expands in the second portion 212.

[0093] The plurality of rod portions 31 are each arranged in a state of being inserted through the through hole 301a of the base body 301. That is, the rotating portion 3A of the present embodiment has three rod portions 31. Each rod portion 31 is slidable with respect to the base body 301 in the penetration direction of the through hole 301a.

[0094] The stopper 33 is arranged in the central rod portion 31 of the plurality of rod portions 31 arranged in the direction of the rotation axis. That is, the rotating portion 3A of the present embodiment has one stopper 33.

[0095] In a state in which the escalator cleaning tool 1A is arranged in the escalator 100, the pair of rotation axes 35 each extend from the shaft support portion 303 of the base 30 in the width direction of the step 110 (the step 110). The rotation axis 35 of the present embodiment is a cylindrical portion extending in the width direction of the step 110.

[0096] The brush portion 4A has a cleaning brush 41A and a cleaning brush holding portion 42A. In addition, the brush portion 4A has a brush portion wheel (wheel) 43. The brush portion 4A of the present embodiment has a pair of cleaning brushes 41A. In addition, the brush portion 4A of the present embodiment has a pair of brush portion wheels 43.

[0097] Each cleaning brush 41A is a cylindrical shape extending in the direction of the rotation axis, and the cleaning brush bristles are arranged around the center axis C3 in 360° in a manner in which each bristle extends toward the radially outer side, and is a so-called roller type cleaning brush.

[0098] The cleaning brush holding portion 42A holds the cleaning brushes 41A at the one-side end portion and the other-side end portion in the orthogonal direction, respectively. The cleaning brush holding portion 42A of the present embodiment holds the pair of cleaning brushes 41A in a manner that each cleaning brush 41A is rotatable about the center axis C3.

[0099] Specifically, the cleaning brush holding portion 42A has a holding portion main body 421 extending in the rotation axis direction and connected to the lower end portions (front end portions) of the respective lever portions 31, and a pair of cleaning brush engaging portions 422 extending in the orthogonal direction in the respective end portions of the holding portion main body 421 and holding the end portions of the cleaning brushes 41A.

[0100] The pair of cleaning brush engaging portions 422 hold the both end portions of the cleaning brush 41A in a manner that the cleaning brush 41A is freely rotatable about the center axis C3. Specifically, each cleaning brush engaging portion 422 extends to one side and the other side in the orthogonal direction with respect to the holding portion main body 421, respectively. Thus, when the rotation direction of the escalator 100 is switched, and each lever portion 31 of the turning portion 3A is moved from one side to the other side with respect to the vertical imaginary line L1 (refer to FIG. 6) with the lower end portion (front end portion) of the lever portion 31 being inclined with respect to the vertical imaginary line L1, it is possible to prevent each lever portion 31 from contacting the corner portion of the step 110 (the corner portion formed by the front end portion of the tread 111 and the upper end portion of the kick plate 112) when each lever portion 31 is rotated about the rotation axis 35. Figure 14A

[0101] Next, the operation of the escalator cleaning tool 1A when the escalator 100 is cleaned by the escalator cleaning tool 1A of the present embodiment will be described.

[0102] When the escalator 100 is in a stopped state, the pair of support portions 2A of the escalator cleaning tool 1A are installed (sucked) to the opposing inner side plates 101, respectively.

[0103] Next, the operation of the escalator cleaning tool 1A when the escalator 100 is cleaned by the escalator cleaning tool 1A of the present embodiment will be described. Figure 14A As shown in FIG. 6, in the case where the escalator 100 is descending, the one-side cleaning brush 41A is in contact with the tread 111 of the descending step 110, and the one-side cleaning brush 41A is rotated about the center axis C3 while cleaning from the front end to the rear end of the tread 111 (refer to FIGS. 6 and 7). Figure 14A Figure 14B At this time, as viewed in the rotation axis direction, the lever portion 31 is inclined with respect to the vertical imaginary line L1 in a manner that the lower end portion of each lever portion 31 is located on the downstream side of the moving direction of the step 110 (the descending moving direction side of the step 110) with respect to the vertical imaginary line L1.

[0104] ​​Then, when the cleaning brush 41A on one side reaches the rear end of the pedal 111, with each rod 31 rotating in the direction of separation from the vertical imaginary line L1 at its lower end and the cleaning brush 41A on one side abutting against the kick plate 112, the cleaning brush 41A rotates around the central axis C3 while cleaning from the lower end to the upper end of the kick plate 112 (see reference). Figure 15A and Figure 15B ).

[0105] During the continuous downward movement of the escalator, the cleaning brush 41A on this side alternately and repeatedly cleans from the front end to the rear end of the step 111 and from the lower end to the upper end of the kick plate 112.

[0106] After a specified period of downward movement, if the escalator 100 is switched to upward movement (i.e., switched to upward movement), the movement direction of each step 110 will be reversed.

[0107] As step 110 moves upward, brush part 4A, which is in contact with pedal 111, moves together with step 110 in the upward direction (see reference). Figure 16 (The solid lines represent the rotating part 3A and the brush part 4A). At this time, as the step 110 moves upward, each rod 31 rotates with its lower end facing the upward movement direction. Furthermore, viewed from the rotation axis direction, each rod 31, relative to the base body 301 (rotation axis 35), decreases in the direction where the distance α2 between the base body 301 (specifically the rotation axis 35) and the brush part 4A decreases (see reference). Figure 16 Slide the arrow β1.

[0108] If each rod 31 continues to rotate, the sliding direction of each rod 31 relative to the base body 301 becomes opposite. That is, while each rod 31 rotates around the rotation axis 35, each rod 31 begins to move relative to the base body 301 (rotation axis 35) in a direction that increases the distance α2 between the base body 301 (rotation axis 35) and the brush part 4A (refer to...). Figure 16 The arrow β2) slides.

[0109] Each rod 31 is fully rotated so that it slides fully until the stop 33 of the central rod 31 abuts against the base body 301 (see reference). Figure 16 The double-dotted rotating part 3A and brush part 4A) prevent the sliding of each rod part 31 (i.e., the sliding stops), and the pedal 111 is cleaned by the cleaning brush 41A on the other side.

[0110] Specifically, with the cleaning brush 41A on the other side abutting against the pedal 111 of the upward-moving step 110, the cleaning brush 41A rotates around the central axis C3 and simultaneously cleans the pedal 111 towards its front end (see reference). Figure 16(The rotating part 3A and brush part 4A of the double-dotted line). At this time, when viewed from the direction of the rotation axis, each rod part 31 is inclined relative to the vertical imaginary line L1 such that the lower end of each rod part 31 is located on the downstream side of the moving direction of the step 110 (the side of the upward moving direction of the step 110) relative to the vertical imaginary line L1.

[0111] Then, when the cleaning brush 41A on the other side reaches the front end of the pedal 111, the rod 31 rotates in the direction of approaching the vertical imaginary line L1 at its lower end. At the same time, the cleaning brush 41A on the other side falls onto the pedal 111 of the next step 110. At this time, viewed from the direction of the rotation axis, each rod 31 is also tilted relative to the vertical imaginary line L1 such that its lower end is located downstream of the vertical imaginary line L1 in the direction of movement of the step 110.

[0112] The cleaning brush 41A, which falls onto the pedal 111 of the next step 110, rotates around the central axis C3 while in contact with the pedal 111, and cleans from the position where the cleaning brush 41A falls towards the front.

[0113] During the continuous upward operation of the escalator 100, the cleaning brush 41A on the other side repeatedly cleans each step 111 from the landing position to the front end.

[0114] Thus, during the cleaning of the escalator 100 by the escalator cleaning tool 1A, when the escalator 100 switches from downward operation to upward operation, the escalator cleaning tool 1A operates as described above. However, when the escalator 100 switches from upward operation to downward operation during the cleaning process, the escalator cleaning tool 1A performs the opposite action to the above.

[0115] In the escalator cleaning tool 1A of this embodiment, the rotating part 3A is at the maximum interval α with respect to the rotation axis 35 and the brush part 4A at a distance α2. max The support part 2A and the brush part 4A are connected in a manner that can be freely added or removed within the following range. Therefore, even if the running direction of the escalator 100 is changed, there will be no conflict with the brush part 4A. Thus, the running direction can be changed during cleaning.

[0116] Further, in the escalator cleaning tool 1A of the present embodiment, the pair of support portions 2A are provided at intervals in the rotation axis direction (the direction in which the rotation axis 35 extends). Thus, since there are two (a pair of) portions that are installed to the inner side plate 101 and support the brush portion 4A and the like, the weight of the brush portion 4A and the like can be more sufficiently supported. That is, in the escalator cleaning tool 1A of the present embodiment, the pair of roller brushes 41A are provided on the brush portion 4A, the base portion 30 and the plurality of rod portions 31 are provided on the turning portion 3A, and the weight is heavy, but since the pair of support portions 2A are installed to the inner side plate 101, respectively, these turning portions 3A and brush portions 4A can be sufficiently supported.

[0117] Further, the escalator cleaning tool of the present application is not limited to the first and second embodiments described above, and various modifications can be added within the scope of the gist of the present application. For example, the structure of another embodiment can be added to the structure of a certain embodiment, or a portion of the structure of a certain embodiment can be replaced with the structure of another embodiment. Also, a portion of the structure of a certain embodiment can be deleted.

[0118] The specific structure of the turning portion 3, 3A that freely increases and decreases the interval α1 between the rotation axis 23, 35 and the brush portion 4, 4A when viewed in the rotation axis direction is not limited. For example, in the turning portions 3, 3A of the first and second embodiments, the interval α1 is increased and decreased by the rod portion 31 sliding with respect to the support portion 2 or the base portion 30, but it can also be a structure in which the rod portion 31 is extended and contracted by an extension and contraction mechanism, or the like.

[0119] Further, in the escalator cleaning tools 1, 1A of the first and second embodiments, the portion (extension portion) that connects the portion 32 that engages with the rotation axis 23 or the portion 301 that has the rotation axis 35 and the brush portion 4, 4A is a rod-shaped portion (rod portion) 31, but it is not limited to this structure, and can be another structure such as a plate shape.

[0120] That is, when the brush portion 4, 4A is pushed against the rotation axis 23, 35 side by the step 110 when the direction of operation of the escalator 100 is switched, it is sufficient that the interval α1, α2 between the rotation axis 23, 35 and the brush portion 4, 4A can be small. Thus, even when the direction of operation of the escalator 100 is switched during cleaning so that the moving direction of the step 110 becomes the opposite direction, damage to the extension portion (rod portion 31 and the like) and the like and the detachment of the support portion 2, 2A from the inner side plate 101 can be prevented.

[0121] Further, the specific number and structure of the stopper 33 in the turning portion 3, 3A is not limited. It is sufficient that it is a number and structure that can prevent the interval between the rotation axis 23, 35 and the brush portion 4, 4A from becoming larger than the maximum interval α max Further, the specific number and structure of the stopper 33 in the turning portion 3, 3A is not limited. It is sufficient that it is a number and structure that can prevent the interval between the rotation axis 23, 35 and the brush portion 4, 4A from becoming larger than the maximum interval α

[0122] Further, in the cleaning tool 1, 1A for escalator, the number of the support portions 2, 2A and the number of the mounting portions 22 in each support portion 2, 2A are not limited. The number of the support portions 2, 2A and the number of the mounting portions 22 in each support portion 2, 2A are only required to be sufficient to support the weight of the rotating portion 3, 3A and the brush portion 4, 4A when cleaning the escalator 100.

[0123] Further, in the brush portion 4, 4A of the cleaning tool 1, 1A for escalator of the first embodiment and the second embodiment, a pair of brush portion wheels 43 are provided, but the number of the brush portion wheels 43 can be one or more than three. Further, the brush portion 4, 4A can not have the brush portion wheels 43.
