The specific embodiment

Followingly embodiments of the invention are described with reference to accompanying drawing.

Fig. 1 is the device of passenger conveyor of expression first embodiment of the invention, the integral structure figure of promptly electronic channel 1.As shown in Figure 1, the electronic channel 1 of present embodiment has framework 3 in the floor 2 that is embedded in building structure, is arranged on the floor, gangway 4,5 of two ends of these framework 3 length directions, the employing circular pattern connects, the polylith pedal 6 that circulation is moved between this floor, gangway 4,5.In addition, this electronic channel 1 possesses along the moving direction of pedal 6 and is arranged on vertically disposed railing 7 on the framework 3 of both sides and via the guiding and the pedal 6 synchronization-moving moving hand-rails 8 of the periphery of this railing 7.And, in this electronic channel 1,, be provided with vertical protection skirtboard 9 for zoning pedal 6 and railing 7.

Fig. 2 is the block diagram of the pedal 6 in the present embodiment escalator.Pedal 6 have pivot suspension wheel 10 and wheel 11 footrest frame 12, be fixed on this footrest frame 12, for stand thereon antislip body 13 of passenger.Connect the pedal 6 that so constitutes by ring-type, and

wheel

10,11 is rotated on this guide rail, so that these pedals 6 circulate between floor, two gangways 4,5 is mobile via the not shown rail guidance that is fixed on the framework 3.

Fig. 3 is the block diagram of antislip body 13.In this antislip body 13, the bottom surface 14U of tread plate 14 is fixed on the base station 13A.

Fig. 4 is the layout circle of the antislip body in former and later two pedals.In the figure, the mutual indentation of recessed portion that is aligned in the tread plate length direction end of outshot in tread plate length direction (moving direction of the pedal 6) end of one of them pedal 6X and another pedal 6Y of tread plate stretches into.It is alternately staggered along its length promptly to be configured to the identical adjacent tread plate of length direction length.Thus, compare, can prevent that passenger's shoes from being blocked by the gap between the pedal of front and back with the occasion that the end of separately antislip body is linearly, or have foreign matter enter before and after gap location between the pedal.

Below describe with regard to the manufacture method of pedal 6.The whole flow process of manufacture method as shown in Figure 5, the processing of at first slotting in the end of sheet steel 17 is to form Fig. 6 and concaveconvex shape (step 1: concavo-convex fluting processing) shown in Figure 7.Concrete method is, the distal process in the two ends of tread plate 14A is gone out, and the other end is recessed.And, to the two ends of adjacent tread plate 14B, form outstanding and recessed with the shape opposite with 14A.

Thus, can use the sheet steel 17 of same shape, the pedal 6X of front and back and the tread plate of 6Y are configured to the shape that mutual indentation stretches into.That is,, all can use the sheet steel 17 of same shape to constitute the pedal that zig-zag disposes regardless of the quantity of the pedal 6 that constitutes electronic channel 1.And, when pedal 6 quantity of electronic channel 1 are even number, for example can form and make 14AT1 (14AS1) and 14AT2 (14AS2) outstanding simultaneously, make the recessed simultaneously shape of 14BT1 (14BS1) and 14BT2 (14BS2), that is to say, even the length that forms the tread plate that the length of length direction is long and length direction is the shape of short tread plate alternate configurations,, just can realize the configuration that zig-zag stretches into as long as the outstanding of front and back pedal swapped round mutually with being recessed into.

Fig. 7 is the partial enlarged drawing of sheet steel 17 shown in Figure 6.As shown in Figure 7, formation is as the 14AT of tread plate 14A end face and as the two ends of the length direction of the part of the 14AS of side, compare with the two ends of the length direction of the part that forms tread plate 14A bottom surface 14AU, set in advance the surplus part (the oblique line part of Fig. 7) of overshooting shape.This surplus part, after sheet steel 17 being bent to wave-like (shape shown in Figure 9), by to the inboard of tread plate 14A (the oblique line part of Fig. 9) direction compacting, the two ends of tread plate form curve form, and the danger that operating personnel and passenger's trick is hooked etc. reduces.In addition, as shown in Figure 7, the two ends of length direction that form the part of tread plate 14A bottom surface 14AU are bent to form and are level and smooth curve shape, so the danger can reduce operation the time.

Sheet steel 17 is bent to the job operation (step 2: the processing of wave-like) describe of wave-like below with reference to Fig. 8.Fig. 8 for example understand to adopt die 15 and punch 16, inserts sheet steel 17, form continuously with the tread plate cooresponding part of 14 end face 14T and with the method for the cooresponding part of bottom surface 14U.By so carrying out processed, sheet steel 17 is formed the antislip body 13 of shape shown in Figure 9.

In addition, the method (step 3: end seal bending machining) of bight that produces in the end of length direction about compacting tread plate 14 to be bent to form curve form, can adopt and use the mould that has curve, carry out pressure-formed method towards the arrow direction from the position of Fig. 9 Z.Thus, 14AS1 and 14AT1 are extruded bending towards the inboard of tread plate (the oblique line part of Fig. 9), thereby form the curved shape that seals as 14V among Fig. 3.Seal bending machining by of this sort end, the bight is formed curve form, the danger that trick is hooked in the time of therefore can reducing the maintenance operation.

In addition, 14K as shown in figure 10 is such, can be with the two ends of the length direction of tread plate bottom surface 14U respectively towards the rear side bending, and carry out rounding processing, can more effectively prevent from like this to be hooked.And the above-mentioned curve 14V that seals can form by press process, so can improve the hardness and the abrasion resistance of antislip body 13.

And, even adopt end side direction in tread plate of tread plate length direction is suppressed crooked method, for example, between 14AS1 and 14AT1, still can there be the gap sometimes.Therefore, by coming this gap of landfill with coating or welding method, thereby can more effectively prevent to be hooked.

Afterwards, adopt fixing means such as spot welding that the bottom surface 14U of each tread plate 14 of antislip body 13 is fixed on base station 13A and go up (step 4: on the base station fixing).Then, as shown in Figure 2, be installed on the footrest frame 12, and wheel 10 and wheel 11 etc. are installed, with assembling pedal 6 (step 5: the pedal overall package).

Below the second embodiment of the present invention is described.The block diagram of the antislip body 13 when Figure 11 is bent to wave-like for the sheet steel 17 in the second embodiment of the invention.That is, in above-mentioned first embodiment, the end of the length direction of the tread plate of adjacent pedal is aligned to the shape that mutual indentation stretches into, but in the present embodiment, the end of adjacent tread plate is linearly separately, is aligned to the shape that is parallel to each other.Certainly, the employing methods identical with first embodiment such as bending machining of sealing of end are carried out.In addition, Figure 12 is the expansion drawing of the sheet steel 17 of the antislip body 13 of formation present embodiment.

The block diagram of the antislip body 13 when in addition, Figure 13 is bent to wave-like for the sheet steel 17 in the third embodiment of the invention.In the present embodiment, for example as shown in figure 14, set in advance reeded sheet steel 17 in the end to the part 14AT that forms the tread plate end face and carry out the processing of wave-like, afterwards, the end of the part 14AS of the tread plate side by will forming its both sides is crooked towards the interior side direction extruding of tread plate, with the gap of landfill tread plate end.

Self-evident, the present invention is not limited to not produce between the adjacent pedal the electronic channel of difference of height, comprises the escalator that produces difference of height between the adjacent pedal, and the present invention is applicable to all device of passenger conveyor.

According to the present invention, can prevent that not only trick from being hooked by the end of antislip body length direction, can also handle the abrasion resistance that improves antislip body by work hardening simultaneously, thereby can realize safer device of passenger conveyor.
