Description

  The present invention relates to a step cleaning tool for a passenger conveyor that cleans a recess among a number of projections and depressions provided in parallel with a step tread.

  In the passenger conveyor, a plurality of steps connected in an endless manner travel from one boarding gate to another boarding gate. On the tread surface of those steps, that is, the surface on which the passenger puts his / her feet, a large number of irregularities extending in the traveling direction of the steps are arranged in a direction perpendicular to the traveling direction of the steps. These irregularities are lined up so as to mesh with a comb provided at the edge of the floor of the entrance. This prevents the passenger's footwear from being caught in the gap between the step and the floor of the entrance / exit.

  Moreover, in the escalator which is a kind of passenger conveyor, the step includes a riser. The riser is provided with a number of irregularities that mesh with the irregularities of the tread surface. This prevents the footwear of the passenger from being caught in the gap between the tread surface and the riser.

  Clay-like dirt is likely to adhere to the recesses of the tread surface and riser unevenness (hereinafter simply referred to as “step recesses”). For this reason, the cleaning which removes the dirt in the crevice of a step is performed by using an exclusive cleaning tool. As a conventional cleaning tool, for example, there is one disclosed in Patent Document 1. The conventional cleaning tool is composed of a member that can be elastically deformed, for example, a foamed member such as urethane foam, and a plurality of convex portions (cleaning portions) that can be fitted into the concave portions of the step. Cleaning of the step recesses using this conventional cleaning tool is performed by sliding the cleaning tool along the recesses in a state where each protrusion is fitted in the step recess. Each convex portion has a shape extending in the sliding direction with respect to the concave portion of the step (longitudinal direction of the concave portion, traveling direction of the step). During the cleaning of the concave portion of the step, the tip of each convex portion is kept pressed against the bottom of the concave portion.

  1st and 2nd embodiment of the cleaning tool of the step of the passenger conveyor of the present invention is described.

[First embodiment]
A first embodiment will be described with reference to FIGS.

  The passenger conveyor cleaned by 1st Embodiment is an escalator, for example. In this escalator, a plurality of steps 60 (see FIG. 8) connected endlessly travels from one entrance / exit to the other entrance / exit. Many treads and recesses 61 (see FIG. 3) extending in the traveling direction of step 60 are provided in a row perpendicular to the traveling direction of step 60 on the tread surface 70 of step 60, that is, the surface on which the passenger puts his / her foot. It has been. These irregularities 61 are lined up so as to mesh with a comb provided on the edge of the floor of the entrance / exit, so that the footwear of the passenger may be sandwiched between the step 60 and the floor of the entrance / exit. It is prevented. Step 60 includes a riser 80 (see FIG. 8). The riser 80 is provided with a large number of projections and depressions that mesh with the projections and depressions of the tread surface 70, thereby preventing passenger footwear from being caught in the gap between the tread surface 70 and the riser 80.

  1st Embodiment cleans the stain | pollution | contamination adhering to the recessed part 62 of the unevenness | corrugation 61 provided in the tread surface 70 of the step 60 and the riser 80, and as shown in FIG. And a plurality of, for example, thirteen cleaning parts 10 to be inserted into the recess 62 and an attachment structure part 20 for attaching the cleaning part 10 to the handle 1.

  As shown in FIGS. 2 and 3, the cleaning unit 10 is provided on a disk part 11 formed to have a thickness dimension that can be inserted into the recess 62 of the step, and a circumferential surface 11 a of the disk part 11. And an angular protrusion 12 extending in the radial direction of the plate portion 11. The recess 62 of step 60 is formed so as to gradually narrow from the opening 63 toward the bottom 64. The depth dimension of the recess 62 is set to 11 mm, the width dimension of the opening 63 of the recess 62 is set in the range of 5.5 to 5.8 mm, and the width dimension of the bottom 64 is larger than that of the opening 63. Is also set in the range of 4.5 to 4.8 mm, which is 10 mm shorter. The thickness of the portion of the disc portion 11 of the cleaning portion 10 that is inserted into the recess 62 gradually decreases toward the peripheral surface 11 a of the disc portion 11 so as to substantially match the shape of the recess 62. The cross-sectional shape of the projecting portion 12 is also formed in the same shape as the cross-sectional shape of the disc portion 11 so as to substantially match the shape of the concave portion 62.

  As shown in FIG. 5, when the configuration of the cleaning unit 10 is like a fiber assembly 90 having a certain direction such as a brush, the surface 100 to be cleaned is stained using the fiber assembly 90. When wiping 101, as shown in FIG. 5A, the fiber assembly 90 is slid against the surface 100 to be cleaned in a state where the fiber assembly 90 stands on the surface 100 to be cleaned. By moving, the dirt 101 can be scraped off at the tip end portion 91 of the fiber assembly 90, whereby the dirt 101 on the surface 100 to be cleaned can be effectively wiped off. On the other hand, as shown in FIG. 5B, the fiber assembly 90 is slid with respect to the surface 100 to be cleaned while the fiber assembly 90 is laid on the surface 100 to be cleaned. In this case, the dirt 101 is likely to be leveled, so that the cleaning efficiency is lower than that shown in FIG. As described above, when the configuration of the cleaning unit 10 is like a fiber assembly 90 having a certain direction such as a brush, the fiber assembly 90 is placed on the surface 100 to be cleaned. The cleaning efficiency is good as long as it can be used in a standing state, but there is a problem that the cleaning efficiency is low when the fiber assembly 90 is bent too much or the elasticity is reduced. On the other hand, the cleaning unit 10 of the present embodiment uses a non-woven material such as the cloth member 13 shown in FIG. 4 and can maintain an appropriate elasticity. Therefore, the tip 91 of the non-woven material fiber generated by the cutting is to be cleaned. The cleaning efficiency is high because it can be held in a state where it is always upright with respect to the surface 100, that is, as shown in FIG. In addition, since the fibers of the nonwoven fabric material are irregularly entangled, the fibers stand up against the surface 100 to be cleaned while maintaining appropriate elasticity with respect to the side portions 65 and 66 of the recess 62 in step 60. Therefore, a cleaning effect higher than that of the fiber assembly 90 having a certain direction such as a brush can be obtained. However, when the nonwoven fabric material is compressed, a force to return to the original size is generated. For example, when the cleaning unit 10 is inserted into the recess 62 of step 60, the thickness of the cleaning unit 10 is the recess of step 60. If it is larger than 62, the cleaning unit 10 is compressed, and a large frictional force is generated due to the force of returning to the original thickness. This produces a wedge effect that significantly increases the sliding resistance of the cleaning unit 10 with respect to the recess 62. This causes the cleaning performance of the cleaning unit 10 to be high, but this wedge effect hinders the sliding operation and may reduce the cleaning efficiency. However, in the present embodiment, the thickness of the portion of the disc portion 11 of the cleaning portion 10 that is inserted into the recess 62 gradually increases toward the peripheral surface 11 a of the disc portion 11 so as to substantially match the shape of the recess 62. It is thin, and the cross-sectional shape of the protruding portion 12 is formed in the same shape as the cross-sectional shape of the disc portion 11 so as to substantially match the shape of the concave portion 62, so the high cleaning performance of the cleaning portion 10 is maintained. In this way, it is possible to prevent the sliding resistance from being remarkably increased and suppress the occurrence of the wedge effect, so that the cleaning efficiency is not lowered.

  The attachment structure portion 20 holds the cleaning portion 10 in a state in which rotation around the center of the disc portion 11 relative to the handle 1 is prevented. Specifically, as shown in FIGS. 1 and 6, the mounting structure portion 20 includes first and second arm portions 31 and 32 extending in parallel, and the first and second arm portions 31 and 32, respectively. The disc portion 11 of the cleaning portion 10 is held between the first and second arm portions 31 and 32 in a non-rotatable manner. Holding structure portion 40.

  The holding structure portion 40 is provided on both of a plurality of shafts, for example, two shafts 50 (see FIG. 7) and the first and second arm portions 31 and 32, and each of the two shafts 50 is inserted therethrough. One end of each of the mounting hole 54 (see FIG. 6B) and the two shafts 50 is fixed, and the frame 30 is attached to the first arm 31 of the first and second arms 31 and 32. The retaining portion 55 (see FIGS. 1 and 7) located in contact with the outside of the disk portion and a portion other than the center of the disc portion 11, for example, two locations sandwiching the center of the circle, are the thickness of the disc portion 11. Two through holes 56 (see FIG. 2) through which the two shafts 50 are individually inserted, and one end of each of the two shafts 50 on the retaining portion 55 side. The second arm of the first and second arm portions 31 and 32 is provided at each of the other end portions opposite to A male screw 53 (see FIGS. 1 and 7) that projects from the frame 32 to the outside of the frame 30, and a wing nut 57 (see FIG. 1) that is a female screw member that is screwed into each of the male screws 53. Is provided.

  The shaft 50 has a circular cross-sectional shape, and includes a large diameter part 51 having one end fixed to the retaining part 55 and a small diameter part 52 extending from the other end of the large diameter part 51. The small diameter portion 52 is provided with the aforementioned male screw 53. The diameter dimension of the mounting hole 54 provided in the second arm portion 32 is smaller than the diameter dimension of the large diameter portion 51. The end surface 51a on the small diameter portion 52 side of the large diameter portion 51 comes into contact with the portion of the second arm portion 32 located on the outer peripheral side of the mounting hole 54 of the second arm portion 32 from the inside of the frame body 30. The second arm portion 32 is restricted from moving in the direction of the first arm portion 31 when the wing nut 57 screwed into the male screw 53 is tightened.

  That is, the two shafts 50 are held in a state where they are inserted through the two mounting holes 54 provided in the first and second arm portions 31 and 32, respectively, and thereby the first and second arm portions. It is spanned between 31 and 32. The two shafts 50 are detachably attached to the first and second arm portions 31 and 32 by a mounting hole 54, a retaining portion 55, a male screw 53, and a wing nut 57.

  In the holding structure portion 40, the two shafts 50 are individually inserted into the two through holes 56 provided at locations other than the center of the disc portion 11 of the cleaning portion 10. These shafts 50 are bridged between the first and second arm portions 31 and 32. Thereby, the holding structure part 40 can hold | maintain the disk part 11 of the cleaning part 10 between the 1st, 2nd arm parts 31 and 32 so that rotation is impossible.

  As shown in FIG. 1, the handle 1 is fixed to the connecting portion 33 of the frame body 30. In a state in which the cleaning unit 10 is held between the first and second arm portions 31 and 32 of the frame body 30, the handle 1 is in a direction perpendicular to the thickness direction of the disk unit 11 with respect to the cleaning unit 10. Thus, the protrusion 12 extends in a direction opposite to the protrusion direction.

  In the first embodiment configured as described above, when attaching the cleaning unit 10 to the first and second arm portions 31 and 32, the operator firstly selects the first of the first and second arm portions 31 and 32. In each of the two mounting holes 54 provided in the one arm portion 31, the other end portions of the two shafts 50 from the outside of the frame body 30 (male screws 53 located on the side opposite to the retaining portion 55). Is inserted between the first and second arm portions 31 and 32. In this state, the operator inserts the other end of each of the two shafts 50 into each of the two through holes 56 provided in each of the disk parts 11 of the 13 cleaning parts 10.

  Thereafter, the operator puts the other end of each of the two shafts 50 into a frame in each of the two mounting holes 54 provided in the second arm portion 32 of the first and second arm portions 31 and 32. The male screws 53 that are inserted from the inside of the body 30 and are provided at the other end portions thereof are projected from the second arm portion 32 to the outside of the frame body 30. In this state, the operator tightens the male nut 53 by screwing the wing nut 57 into it. Accordingly, the first and second arm portions 31 and 32 are sandwiched between the retaining portion 55 and the wing nut 57. As a result, the two shafts 50 inserted through the two through holes 56 provided in the disc part 11 of the cleaning part 10 are fixed to the first and second arm parts 31 and 32. Thus, the attachment of the cleaning unit 10 to the first and second arm portions 31 and 32 is completed.

  When removing the cleaning unit 10 from the first and second arm portions 31 and 32, the operator first removes the wing nuts 57 from the male screws 53 of the two shafts 50. Next, the operator holds the retaining portion 55 and moves the retaining portion 55 in a direction away from the first arm portion 31, so that the worker is provided on both the first and second arm portions 31 and 32. Each of the two shafts 50 is pulled out from each of the two mounting holes 54 and each of the two through holes 56 provided in the disc portion 11 of the cleaning unit 10. As a result, the removal of the cleaning unit 10 from the first and second arm portions 31 and 32 is completed.

  As described above, in the first embodiment, the two shafts 50 can be detached from the first and second arm portions 31 and 32 and are detached from the first and second arm portions 31 and 32. Each of the two shafts 50 can be extracted from each of the two through holes 56 provided in the disk portion 11 of the cleaning unit 10. That is, in the first embodiment, the cleaning unit 10 can be replaced.

  When cleaning the recessed portion 62 of the tread surface 70 in step 60 using the first embodiment, as shown in FIG. 8, the operator can use the thickness direction of the disc portion 11 of the cleaning unit 10 and the recessed portion of step 60. The disc portion 11 is inserted into the recess 62 so that the circumferential surface 11a of the disc portion 11 is pressed against the bottom 64 of the recess 62 in a state where the width direction of 62 (the direction orthogonal to the traveling direction of step 60) is matched. To do. Then, by sliding the disc part 11 in the longitudinal direction of the recess 62 (traveling direction of step 60) with respect to the recess 62, the dirt adhering to the bottom 64 and the side parts 65, 66 of the recess 62 is removed. Wipe off with 11.

  During the sliding of the disc part 11 of the cleaning part with respect to the concave part 62 of step 60, the handle 1 and around the center of the disc part 11 are caused by the sliding resistance generated between the concave part 62 and the disc part 11 of step 60. Although the angle of the disc part 11 changes from the state of FIG. 8A to the state of FIG. 8B or vice versa, the operator returns the angles of the handle 1 and the disc part 11. The peripheral surface 11a of the disc part 11 can always be kept pressed against the bottom part 64 of the recess 62 in step 60. Thereby, 1st Embodiment can eliminate the troublesomeness which adjusts the attitude | position of the cleaning part 10 inserted in the recessed part 62 of step 60. FIG.

  Further, the cleaning unit 10 is pressed against the peripheral surface 11a of the disk part 11 against the bottom part 64 of the concave part 62 in a state where the thickness direction of the disk part 11 and the width direction of the concave part 62 of the step 60 are matched. Therefore, the disk part 11 is unlikely to be deformed with a wedge effect when the disk part 11 slides with respect to the concave part 62 of step 60. Thereby, 1st Embodiment can reduce the sliding resistance with respect to the recessed part 62 of step 60 of the cleaning part 10 conventionally.

  When the concave portion of the riser 80 in step 60 is cleaned using the first embodiment, as shown in FIG. 9, the operator can use the riser 80 in the upper step 60 and the tread 70 in the lower step 60. The projecting portion 12 of the cleaning portion 10 can be inserted into the boundary portion 81. That is, the first embodiment can facilitate the cleaning of the recess of the riser 80 in step 60.

  In the first embodiment described above, the escalator step 60 is set as the cleaning target, but the moving sidewalk step may be set as the cleaning target. In addition, there is a moving sidewalk step that does not include a riser, and in this case, the cleaning unit 10 may be only the disk unit 11 that does not include the protrusion 12.

  In the first and second embodiments described above, the disc portion 11 of the cleaning portion 10 is formed to be gradually thinner so that the thickness of the portion inserted into the recess 62 in step 60 substantially matches the shape of the recess 62. The shape of the protrusion 12 is the same as that of the disc 11. The shape of the disk part and the protrusion part in the present invention is not limited thereto, and may be the disk part 201 shown in FIG. 11 or the disk part 202 shown in FIG.

  The disc part 201 shown in FIG. 11 is formed to have a constant thickness with a thickness dimension of 6 to 8 mm longer than the width dimension of 5.5 to 5.8 mm of the opening 63 of the recess 62 in step 60. These are inserted into the recesses 62 while being compressed in the thickness direction. When the concave portion 62 is cleaned by the disc portion 201, the disc portion 11 of the cleaning portion 10 is pressed against the side portions 65 and 66 of the concave portion 62 by the elastic force. , 66 can be wiped off more effectively than in the case of the disk portion 11. However, when taking such a form, it is necessary to adjust the elastic force of the cleaning part 10 so that sliding resistance may not increase remarkably. Thus, if an elastic force can be adjusted appropriately, since it can suppress that a wedge effect expresses, maintaining the high cleaning performance of the cleaning part 10, a cleaning efficiency can also be made not to fall.

  The disc portion 202 shown in FIG. 12 is shorter than the width dimension 5.5 to 5.8 mm of the opening 63 of the recess 62 in step 60 and longer than the width dimension 4.5 to 4.8 mm of the bottom portion 64. It is formed to a constant thickness with a dimension of 5 mm, and is inserted into the recess 62. When cleaning the concave portion 62 with the disc portion 202, the sliding resistance received by the disc portion 202 from the concave portion 62 is smaller than in the case of the aforementioned disc portion 11. The plate part 11 can be smoothly slid. However, when the dirt on the side portions 65 and 66 of the recess 62 is wiped off, it is necessary to incline the disc portion 202 in the direction of the arrow B and contact the side portion 65 or the side portion 66. By doing in this way, it can suppress that a wedge effect expresses, maintaining the high cleaning performance of the cleaning part 10, Therefore A cleaning efficiency can also be made not to fall.

  In the first and second embodiments described above, the disk portion 11 of the cleaning unit 10 is formed by laminating a plurality of cloth members 13 formed by cutting a nonwoven fabric material into a side view shape of the cleaning unit 10 as shown in FIG. In this state, the fabric member is heated and compressed in the laminating direction, or the fabric member is laminated and bonded in a laminated state, or the fabric member 13 is not laminated. 13, the nonwoven fabric fiber is heated and compressed and then ground and cut so as to match the shape of the recess 62 in Step 60, that is, it is made of only a nonwoven material. It is a thing. In the present invention, the member constituting the disk part is not limited to the nonwoven material alone, but a nonwoven material on which a core material 204 having higher rigidity than the nonwoven material is laminated, such as the disk part 203 shown in FIG. It may be provided at the center of the material. The disk part 203 configured as described above is less likely to be deformed with a wedge effect than the above-described disk part 11 when the disk part 203 slides with respect to the recess 62. Therefore, the disk part 203 can reduce the sliding resistance which the disk part 203 receives from the recessed part 62 rather than the case of the disk part 11. FIG. Further, even when the thickness is greater than the width of the recess 62, it can be easily slid against the sliding resistance when inserted into the recess 62, and the deformation of the cleaning unit 10 can be suppressed. Since the wedge effect is not exhibited, the wedge effect can be suppressed while maintaining the high cleaning performance of the cleaning unit 10, and the cleaning efficiency cannot be reduced.

  In addition, the shape of the part inserted in the recessed part 62 of the disc part 203 is not limited to what is shown in FIG. For example, the thickness dimension of the disc portion 203 disposed in the opening 63 of the recess 62 is set within a range of 5.5 to 8 mm, and the thickness dimension of the disc portion 203 disposed in the bottom portion 64 of the recess 62 is set. Is set within a range of 4 to 4.8 mm.
