A low friction coating layer is provided on the surface of the skirt guard panel so that steps and passengers can move smoothly.

JP 2001-118942 A

  In the passenger conveyor as described above, when the passenger is moving on the step, the tip of the passenger's shoes and the luggage hit the skirt guard panel, the low friction coating layer is peeled off, and the side edge of the step and the skirt guard panel A gap is generated between the two and passengers' shoes and skirts are easily caught. Therefore, it is necessary to replace the skirt guard panel or repaint the low friction coating layer.

  However, replacing the skirt guard panel is economically expensive, and if the low friction coating layer is painted again, drying time is required, during which the passenger conveyor is not used, and color unevenness occurs in the painted area. There was a problem that it was generated and looked bad.

  Then, embodiment of this invention aims at providing the repair method of a passenger conveyor using the skirt guard panel which can lengthen a lifetime.

  In an embodiment of the present invention, a low friction coating layer having a friction coefficient smaller than the friction coefficient of the metal plate is provided on the entire front surface and the entire back surface of the metal plate, respectively.

(3) Skirt guard 44
The structure of the skirt guard 44 will be described with reference to FIGS.

  As shown in FIG. 1, the skirt guard 44 includes a plurality of skirt guard panels (hereinafter simply referred to as “panels”) 441 to 447 along the traveling direction of the steps 30. Among these, the panels 443, 444, and 445 are rectangles that are long in the front-rear direction, and are front-back symmetrical. Here, the “front and back symmetric shape” means that even if the panels 443 to 445 are reversed, the same shape is obtained (see FIG. 4). The panels 441, 442, 446, and 447 are asymmetrical because they are provided from the getting-on / off portion of the escalator 10 to the inclined portion and from the inclined portion to the getting-on / off portion. Here, the “front and back asymmetric shape” means that the same shape is not obtained even if the front and back sides are reversed (see FIG. 6).

  As shown in FIG. 4, the rectangular panel 443 is made of a rectangular metal plate 450, and six attachment holes 451 are provided on the peripheral edge thereof. As shown in the enlarged view of FIG. 5, dishing is performed on the front surface side and the back surface side of each mounting hole 451 to form a frustoconical peripheral portion 452. The centers of the frustoconical peripheral part 452 on the front surface side and the frustoconical peripheral part 452 on the back side are coaxial.

  As shown in the enlarged view of FIG. 5, a low friction coating layer 453 is formed on the entire front surface and back surface of the metal plate 450. The low friction coating layer 453 has a friction coefficient smaller than that of the metal plate 450 itself.

  Other panels 441, 442, 444, 445, 446, 447 are also provided with a plurality of mounting holes 451 at the peripheral edge of the metal plate 450, as in the case of the panel 443. As a result, a frustoconical peripheral portion 452 is formed, and a low friction coating layer 453 is formed on both sides.

  By the way, as shown in FIGS. 2 and 3, a fixed support portion 460 formed by bending a metal plate is fixed to the upper portion of the truss 12 in the vertical direction via a fixing member (not shown).

  As shown in FIG. 3, the panel 443 is disposed on the fixed support portion 460 via a sheet-like cushioning material 461, and is fixed to the fixed support portion 460 with a flat head screw 462. As shown in FIG. 2, the countersunk screw 462 is screwed from the front surface side of the panel 443, that is, from the step 30 side toward the back surface side. The head of the countersunk screw 462 does not protrude from the panel 443 because it enters the frustoconical peripheral portion 452. Further, the head of the countersunk screw 462 at the top is arranged and concealed inside the inner ledge 367, and the head of the countersunk screw 462 at the bottom is arranged and concealed at the side end of the step 30. Therefore, the head of the countersunk screw 462 cannot be seen by the passenger.

(4) Repair method of the escalator 10 In the escalator 10 having the above-described configuration, a repair method in the case where a shoe or a bag of a passenger hits, the panels 441 to 447 of the skirt guard 44 are damaged, and the low friction coating layer 453 is peeled off. explain.

  First, the case where the low-friction coating layer 453 of the panel 443 having a front and back symmetry is peeled will be described. In order to remove the damaged panel 443, the operator removes the flat head screw 462 and removes the panel 443 from the fixed support portion 460.

  Next, the operator reverses the front surface and the back surface of the panel 443 and places the panel 443 on the fixed support portion 460 so that the back surface is on the step 30 side.

  Next, the operator fixes the panel 443 to the fixed support portion 460 again with a flat head screw 462.

  By attaching in this way, the surface of the damaged panel 443 becomes the inside of the balustrade 36, and the back surface of the clean panel 443 that is not damaged is exposed to the step 30 side. And since the low friction coating layer 453 is formed also on the back surface of the panel 443 similarly to the surface, the step 30 and the passenger can move smoothly. Further, since the frustoconical peripheral portion 452 is also provided on the back surface of the mounting hole 451, the flat head screw 462 does not protrude in the same manner as the front surface.

  Next, a repair method when the surface of the left-side panel 446 of the asymmetrical front and back shown in FIG. 6 is damaged will be described. The operator removes the left panel 446 and the right panel 446 from the left fixed support 460 and the right fixed support 460, respectively.

  Next, the operator attaches the removed left panel 446 to the right fixed support portion 460. At this time, the worker attaches the left damaged panel 446 so that the front surface of the left panel 446 is inside and the back surface of the left panel 446 is outside (the step 30 side).

  Next, the operator attaches the removed right panel 446 to the left fixed support portion 460. At this time, the operator attaches the right panel 446 so that the surface of the right panel 446 is on the inside and the back surface of the right panel 446 is on the outside (the step 30 side).

  Since the low friction coating layer 453 is formed on the back surfaces of the left and right panels 446, the steps 30 and passengers can move smoothly. In addition, since the frustoconical peripheral portion 452 is also formed on the back surface of the mounting hole 451, the flat head screw 462 does not protrude. What is important here is that even if the panel 446 has an asymmetrical shape, if the left panel 446 is attached to the right side and the right panel 446 is attached to the left side, the front and back are reversed and can be attached as they are.

(5) Effect According to the present embodiment, when the front and back symmetrical panels 443 to 445 are formed, a clean low friction coating layer 453 that is not damaged is formed only by reversing the front and back even if the surface is damaged. The back surface thus made becomes the outside, and the panels 443 to 445 are repaired, and the service life is doubled.

  Also, if the front and back asymmetric panels 441, 442, 446, 447 are used, the damaged surface becomes the inner side by simply replacing the left and right panels, and the rear surface on which the clean low friction coating layer 453 is formed is the outer side (the step 30 side). ) And repaired, and even the front and back asymmetric panels 441, 442, 446, 447 double the life.

  Further, since the front surface and the back surface of the mounting holes 451 of the panels 441 to 447 are respectively subjected to countersunk processing to form a frustoconical peripheral portion 452, even if the front and back are reversed and fixed with the countersunk screws 462, the countersunk screws 462 The head does not protrude.

(6) Modification Example In the above embodiment, the structure in which the panels 441 to 447 are attached with the countersunk screws 462 has been described. However, in the case of attaching with the bolts, the counterbore holes may be formed on the front surface side and the back surface side of the attachment holes 451. .

  In the said embodiment, although the balustrade panel was demonstrated with the glass plate 360, it replaced with this and a stainless steel plate may be sufficient.

  Moreover, in the said embodiment, although it was the structure attached with the countersunk screw 462 from both the surface side of the one attachment hole 451, and a back surface side, it replaces with this and the attachment hole 451 which screws the countersunk screw 462 from the surface side, The attachment holes 451 for screwing the countersunk screws 462 from the back side may be provided at different positions. Even in this case, the attachment hole 451 is provided at a position where the inner ledge 367 and the step 30 are hidden. When the countersunk screw 462 is screwed from the front side, the countersink is applied only to the front side of the mounting hole 451, and when the countersunk screw 462 is screwed from the back side, All you need to do is plate processing.

  Similarly, in the case of fixing with a bolt, when fixing the bolt only from the front surface side, the counterbore processing is performed only on the front surface side of the mounting hole 451, and when fixing the bolt only from the rear surface side, It is only necessary to perform counterbore processing on the back surface side of the attachment hole 451.

  Moreover, in the said embodiment, although demonstrated applying to the escalator 10, you may replace with this and may apply to the moving sidewalk.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
