  In the overall configuration of the escalator shown in FIG. 1, the escalator 1 includes a step 2 that is connected endlessly and moves, and a pair of balustrades 3 are provided upright on both sides of the step 2.

  2 and 3, the skirt guard 4 is provided between the step 2 and the balustrade 3 substantially vertically with a slight gap from the side of the step 2. The upper part of the skirt guard 4 is fixed to the deck base 5 with a countersunk screw 6.

  A balustrade panel 7 is erected on the balustrade 3, and an inner deck 8 is provided between the inner surface of the balustrade panel 7 and the upper edge of the skirt guard 4 so as to be inclined toward the step 2. The lower end portion of the inner deck 8 is superimposed on the upper end of the deck base 5 and is fixed to the deck base 5 with screws 9.

  The molding 10 provided so as to cover the screws 9 for fixing the inner deck 8 is formed of, for example, an aluminum extruded material, has a substantially convex cross section, protrudes to the step 2 side, and is accommodated in the molding 10. It is fixed to the deck base 5 via the skirt guard 4 by the hidden bolt 11. On the lower surface of the molding 10, a guide groove 10a having an opening below is formed in a direction intersecting the longitudinal direction.

  As shown in FIGS. 2 and 3, the hidden bolt 11 is fixed to the deck base 5 via the guide piece 12. The guide piece 12 has a shape that fits into a guide groove 10 a provided in the molding 10, and the hidden bolt 11 is inserted through the guide piece 12 and fixed to the deck base 5 together with the molding 10.

  FIG. 4 shows the process of mounting the mall 10. In the joint of two continuous moldings 10, the ends of the molding 10 are formed obliquely with an acute angle θ with respect to the longitudinal direction of the molding. An angle θ formed by the molding longitudinal direction and the molding 10 joint is set to satisfy 0 ° <θ <90 °.

  As shown in FIG. 3, the skirt guard 4 is previously provided with a countersunk screw 6 and a long hole 4 a for the hidden bolt 11, and the inner deck 8 is provided with a notch hole 8 a for the screw 9. The molding 10 is provided with a long hole 10b for tightening the hidden bolt 11. The deck base 5 is provided with a long hole 5 a so as to correspond to the long hole 10 b of the molding 10 and the notch hole 8 a of the inner deck 8.

  As shown in FIG. 5 which is a YY sectional view of FIG. 4 and FIG. 6 which is a ZZ sectional view of FIG. 4, when assembling the balustrade portion, the upper end of the skirt guard 4 is overlapped with the deck base 5, Secure with screws 6. At this time, the countersunk screw 6 does not protrude from the surface of the skirt guard 4. Next, the lower end portion of the inner deck 8 is overlaid on the deck base 5 and fixed with screws 9.

  Next, the hidden bolt 11 is inserted into the guide piece 12 for the molding 10 and temporarily fixed to the deck base 5 through the long hole 4 a of the skirt guard 4. At this time, an engagement groove 10 c is formed inside the molding 10, and an engagement rib 12 a that engages with the engagement groove 10 c is formed on the guide piece 12. And it inserts from the balustrade 3 upper direction along angle (theta) provided in the molding 10 joint so that the guide groove 10a provided in the molding 10 and the guide piece 12 may fit, and the oblong hole which provided the concealed bolt 11 in the front of the molding 10 The molding 10 is fixed by tightening with a tool or the like using 10b.

  Therefore, when the engagement groove 10c of the molding 10 and the engagement rib 12a of the guide piece 12 are engaged, the molding 10 is securely fixed to the deck base 5. The width of the long hole of the long hole 10 b is narrow so that the hidden bolt 11 does not fall off the surface of the molding 10. However, a tool or the like can be passed through the long hole 10b, whereby the hidden bolt 11 can be fastened.

  Thereby, it is possible to prevent the passenger's body from being sandwiched between the skirt guard 4 and the step 2 by securely fixing the molding 10 protruding to the step 2 side to the deck base 5.

Further, since the molding 10 is attached so as to cover the countersunk screw 6 and the screw 9 and the molding 10 is fixed to the deck base 5 with the concealing bolt 11, the head of the countersunk screw 6 and the screw 9 is exposed to the molding surface due to loosening. There is no damage caused by catching clothes.
Further, the concealing bolt 11 is temporarily fixed to the predetermined position corresponding to the mall long hole 10b on the deck base 5 side through the guide piece 12, so that the concealing bolt 11 is positioned after the concealing bolt 11 is inserted into the molding 10. Preliminary work becomes unnecessary.

  Further, as shown in FIG. 7, the molding 10 has an angle θ of 0 ° <θ <90 ° with respect to the longitudinal direction of the molding 10 so that the molding 10 is not easily detached from the deck base 5. be able to. For example, when the mall 10 receives a horizontal pressing force 14 from the lower end direction of the mall 10 by a load such as a carryback wheel 13 of an escalator passenger, a component force 15a of the horizontal pressing force 15 acting on the mall 10 and Since 15b acts in the direction in which the molding joint is pressed, the molding 10 can be made difficult to come off from the deck base 5. Here, the component force 15 b is a component force in the longitudinal direction of the molding 10, and the component force 15 a is a component force in a direction perpendicular to the longitudinal direction of the molding 10. When the angle θ = 90 °, the component force 15a cannot be received, but when the angle θ <90 °, the component force 15a can be received. The upper limit of the angle θ is preferably θ ≦ 80 °. Further, if the lower limit of the angle θ is too small, the seam becomes longer, so it is desirable that 35 ° ≦ θ.

  Furthermore, in the case of an escalator, it is desirable that θ ≦ 55 °. In general, the inclination angle of the escalator is 30 °, and by setting θ ≦ 55 °, the angle at the 10th joint of the molding becomes an angle rotated clockwise from the vertical direction. 10 becomes more difficult to come off. In the case of an escalator, the angle θ is an angle formed by the longitudinal direction of the molding 10 and the joint on the lower floor side of the molding 10 provided on the upper floor side.

  Further, in the case of a moving sidewalk, it is desirable that θ ≦ 80 ° in order to face the force acting in the vertical direction. If the lower limit of the angle θ is too small, the seam becomes longer, so it is desirable that 35 ° ≦ θ.
