Rutotomoni and a screw that fastens the deck back plate and the deck bracket through said first hole of said inner deck.

  In the balustrade apparatus for the man conveyor according to the present invention, the screw for fixing the inner deck to the skirt angle is not exposed to the step side, so that the screw protrudes to the step side due to the loosening of the screw. Absent.

Hereinafter, each embodiment of the present invention will be described, but the same or equivalent members and parts will be described with the same reference numerals.
Embodiment 1 FIG.
1 is a configuration diagram of an escalator according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG.
The escalator, which is a man conveyor, has a pair of balustrade panels 13 erected on both sides of the step 1 along the direction of movement of the step 1 and a balustrade device 3 fixed to the main frame 2. It has been.
The balustrade apparatus 3 includes a skirt bracket 4 fixed to the main frame 2, a skirt angle 5 fixed to the skirt bracket 4 by a bolt 6, and a side face of the step 1 fixed to the skirt angle 5 by a countersunk screw 7. And a skirt panel 8 facing each other with a slight gap, and a deck bracket 9 fixed to the side opposite to the step 1 of the skirt angle 5.

  Further, the balustrade apparatus 3 includes a holder 10 fixed to the main frame 2, a contact plate 11 facing the support 10, and a gap between the contact plate 11 and the support 10 via a packing 12. The bolt balus 14 that penetrates the balustrade panel 13, the batting plate 11, the balustrade panel 13, and the holder 10 that are sandwiched between the baling plate 11, the balustrade panel 13, and the holder 10, and the holder 10 The outer deck 17 made of stainless steel with one end fixed and bent at the other end inserted into the outer ornament 15 and the outer ornament 15 made of synthetic resin are fixed to the holder 10 via the clasp 18. Screw 19.

Further, the balustrade apparatus 3 includes a deck back plate 22 having a cross-sectional shape fixed to the deck bracket 9 with a screw 21 via a washer 20, and a screw seat plate 23 screwed to the end of the screw 21. The inner deck 24 made of stainless steel fixed to the end portion of the deck back plate 22 by welding, the inner ornament 16 in which the bent end portion of the inner deck 24 is inserted, and the inner ornament made of synthetic resin The deck bracket 9 fixed to the skirt angle 5 by welding is provided with a screw 26 fixed to the backing plate 11 via a clasp 25. As shown in FIG. A plurality of L-shaped third holes 9A are formed.
As shown in FIGS. 4A and 4B, the inner deck 24 is formed with a long hole 24A that is a first hole extending in the lateral direction. Further, as shown in FIGS. 4A and 4C, the deck back plate 22 is formed with a long hole 22A which is a second hole extending in the lateral direction. The long hole 22A and the long hole 24A formed in the inner deck 24 face each other and have the same dimensions. The size of the long holes 22A and 24A is smaller than the diameter of the head 21A of the screw 21.
In the above description of the balustrade apparatus 3, the configuration of only one side of the step 1 has been described, but the configuration of the other side is the same, and the description of the configuration of the other side is omitted.

Next, a procedure for fixing the inner deck 24 of the balustrade apparatus 3 to the deck bracket 9 will be described.
As shown in FIG. 5, a screw 21 passes through a long hole 22 </ b> A of the deck back plate 22 fixed to the inner deck 24 in advance via a washer 20. In addition, a screw seat plate 23 is provided at the end of the screw 21 so that the screw thread is crushed and cannot be removed.
In this state, the screw 21 is inserted from the short portion 9A1 (see FIG. 3) of the long hole 9A of the deck bracket 9. At this time, the upper portion of the deck bracket 9 is sandwiched between the screw seat plate 23 and the lower portion of the deck back plate 22.
Next, the bent end portion of the inner deck 24 is inserted into the groove portion of the inner ornament 16, and then a screwdriver is inserted through the long hole 24 </ b> A, and the screw together with the inner deck 24 and the deck back plate 22 as shown in FIG. 6. 21 is moved to the bottom side of the long hole 9A2. Finally, the inner deck 24 is fixed to the deck bracket 9 by rotating the screw 21 in one direction by a driver.

According to the balustrade apparatus 3 configured as described above, even if the screw 21 is loosened, the size of the elongated hole 24A of the inner deck 24 is smaller than the size of the head 21A of the screw 21, so that the screw 21 is on the inner side. No more jumping out than deck 24.
Further, as shown in FIG. 7, the necessary exchange of the inner deck 24 can be easily performed by taking in and out only the inner deck 24 that is necessary in a direction perpendicular to the ascending / descending direction of the step 1.

Embodiment 2. FIG.
In this embodiment, as shown in FIG. 8, the opening 29A1 of the long hole 29A, which is the third hole of the deck bracket 29, has an enlarged shape that is enlarged along the upward direction. Other configurations are the same as those in the first embodiment.
According to the balustrade apparatus 3, when the screw 21 is inserted into the long hole 29A of the deck bracket 29 and the inner deck 24 is fixed to the deck bracket 9, the opening 29A1 of the long hole 29A is wide. Therefore, the screw 21 is smoothly inserted into the long hole 29A, and the workability of fixing the inner deck 24 to the deck bracket 9 is improved.

Embodiment 3 FIG.
In the first and second embodiments, the lateral dimensions of the deck back plate 22 and the inner deck 24 are the same. Actually, however, the size of the deck back plate 22 is larger than the inner deck 24 due to manufacturing errors of both. If it is longer than that, a gap may be generated between the adjacent inner decks 24, and the appearance may be poor.
In this embodiment, since the overall length of the deck back plate 22 in the lateral direction is shorter than that of the inner deck 24, there is no gap between the adjacent inner decks 24. Does not occur.

Embodiment 4 FIG.
In this embodiment, as shown in FIG. 9, a lid 50 that closes the long hole 24 </ b> A is provided in the long hole 24 </ b> A that is the first hole of the inner deck 24.
Other embodiments are the same as those in the first embodiment.
According to this embodiment, it is possible to prevent the fingertip from being inserted into the long hole 24A due to, for example, mischief of a child.

Embodiment 5 FIG.
