Description of the Invention (1) Field of the Invention / The present invention relates to a handrail driving device for a person's conveyor belt. Description of the conventional technique Figures 1 to 3 show a conventional handrail drive for a person conveyor. In these figures, the main frame 1 generally refers to the truss that constitutes the main body of the personnel conveyor. In the main frame 1, a footrest portion 2 is arranged so as to go up and down the stairs along the guide rails 3a, 3b of the front and rear wheels; 4a and 4b. The foot part 2 is composed of a plurality of steps linked to each other, and forms an endless conveyor belt passing through the shaft part. Each axis individually passes through the links of the left and right foot chains, and each step is composed of six Consisting of connecting rods. The footrest driver 5 is near the horizontal end of the upper step side of the main frame 1. The pedal section actuator 5 is composed of a motor, a reduction gear set, and driving chain teeth of the left and right pedal chains (others not shown). The ring-shaped handrail 6 of the main frame 1 is pulled into the main frame through the outer periphery of the low rails on the left and right sides. The left and right handrails 6 are driven by the driving unit 'and move in synchronization with the footrest portion 2. Since the conventional person conveyor belt armrest driving device includes a pair of mechanisms symmetrically disposed in the main frame 1, a single-sided mechanism will be described below. A handrail chain sprocket 7 is arranged to co-operate with the foot chain drive sprocket gear formed in the foot pedal driver 5 as described above. Adjacent to the inclined portion of the horizontal portion of the main frame 1, a relay idler 9 is disposed, which operates together with the armrest chain sprocket through the intermediary of the first armrest driving chain 8. The relay idler 9 further includes an outer sprocket gear 9 b, and the second support (please read the precautions on the back page first). I installed it! II Order ·! — Γ. This paper size applies to the Chinese national standard (CNS ) A4 size (210 X 297 mm) 4 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 498048 A7 B7 V. Description of the invention (2) The hand drive chain 10 surrounds it. The outer chain gear 9 b is wound around Rear 'second armrest driving chain 10 is wound around the idler pulley 1 1 of the inclined portion of the main frame. Then, the chain 10 is raised and continuously winds the individual sprocket teeth. Wheel 13 and relay idler 1 4 ° sprocket gears 13 are coaxial with most (four in each) handrail drive wheels 1 2 'handrail drive wheels 12 are placed straight along the handrail belt 6. Further, a second handrail drive chain 10 is lowered, and after winding the tension roller 15 of the tensioner 15 15a, it returns to the relay idler 9. The relay idler 9 is provided with a horizontally protruding tension adjusting bolt 9c. The operation of the idler 9 towards the opposite direction of the driving sprocket 7 'the bolt 9 c allows the first armrest to drive the chain 8 Relaxation and expansion 'were adjusted. Similarly, a tensioner 15 with a tension adjustment screw 15b is provided on the lower side. Operating the screw 1 5b pushes the tensioner 15b down so that the second The armrest driving chain 10 can be loosened and expanded 'for adjustment. In the conventional person conveyor belt armrest driving device, the armrest driving chain should be driven coaxially with the pedal chain driving chain gear of the pedal driver 5 integrally and coaxially. When gearing, the relay idler 9 is rotated by the first armrest driving chain 8 and, in addition, the second armrest driving chain 10 is rotated, and the individual armrest driving wheels 12 are also rotated to drive the armrest belt 6 by friction. Further ' The rollers 16 are arranged in series with each other, and are individually built into the handrail belt 6 from the lower part with respect to the handrail drive wheels 12. In this way, since the handrail drive wheels 12 push against the handrail belt 6 under pressure, the handrail drive wheels 12 are frictionally driven. The force is transferred to the handrail belt 6. At the same time, with the increase in the application diversity of the handrail drive device, in recent years, this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read first Back of Matters needing attention Willie page i!

Description of the invention (3), the personnel conveyor belt must be set outdoors and has a longer lifting span Corresponding to this, it is necessary to increase the driving force of the device to avoid raindrops on the handrail, sliding relative to the handrail unit, or to increase the movement resistance. 〇 For this demand, it is expected to strengthen the handrail driving wheels 12 and Corresponding to the pressure of the roller 16 of the handrail belt 6. However, this response method is not preferable because it makes the lifting span of the handrail belt 6, the handrail driving wheel 12 and the roller 16 shorter. Therefore, it is usually adopted to increase the number of driving wheels and rollers. FIG. 4 shows a conventional armrest driving device using the above-mentioned response means. Therefore, in addition to the four pairs of driving wheels 12 and four rollers 16 of FIG. 1, the illustrated device is provided with four armrest driving wheels 22 and four rollers 26. In this configuration, the second handrail driving chain 20 is wound around the relay idler 9 and the idler 11 and further passed through the intermediate idler 1 4 and wound around the four handrails. On the continuous chain sprocket of wheel 12. Then, after winding the intermediate idler wheels 2 7 and 28, the chain 20 is further wound around the chain wheel 2 3 of the four handrail driving wheels through the relay idler 2 4 and finally wound to the low tensioner. 1 5 on the tension roller 15a. According to the above-mentioned configuration, similar to the description of the conventional device of FIG. 1, the footrest driver 5 allows the armrest to drive the sprocket gear 7, the cooperative drive chain 9, the relay idler 9 and the cooperative drive chain 20 to rotate in an interrelated manner. Therefore, the four armrest driving wheels 12 and the four armrest driving wheels 22 are rotated to frictionally drive the armrest belt 6 in the same manner as the rollers 16〃, 26. In this way, when the number of driving wheels and rollers is increased, the driving force of the handrail can be increased. This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) (Please read the note on the back page). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. -6-498048 A7 _ B7 V. Description of the Invention (4) However, the above armrest driving device still has the following problems. That is, to increase the number of "the handrail driving wheels and the rollers, so that the second handrail driving chain excessively increases" and it is necessary to interpose the idler wheels 27, 27. Therefore, the hand drive device of this structure is relatively complicated, and it is necessary to adjust multiple idlers and chain gears on the same straight line, thereby making the installation or maintenance of the device difficult and difficult. In order to solve the shortcomings of this device, a handrail driving device is further proposed, which is equipped with a pedal chain as a power source, such as Japanese Unexamined Patent Publication (KoKa i) No. 9-86846. The pedal chain is generally provided with a perforation into which a shaft portion having two front wheels is interposed. Each perforation is located at the central part of the adjacent peg, and at the same time each foot part is fastened to the shaft part passing through the through hole. To cope with this structure, it is necessary to eliminate one tooth of the sprocket gear, since the tooth will interfere with the connecting rod connected to the shaft portion. This sprocket gear is used to power the pedal chain. When applying this structure to the upper turning part of the device, this elimination does not cause any difficulties. At the upper turning part, the chain is tightly fitted to the sprocket gear by its multiple racks. However, problems can arise if one tooth of a chain that closely fits in a linear movement is eliminated from the sprocket gear. Because this elimination will degrade the fit between the chain gear and the chain 'and thus affect the smooth movement between the two. Summary of the Invention Therefore, the object of the present invention is to provide a handrail for a personnel conveyor.

If the number of rides is too large, the handrail-driven chain sprocket 50 will become embarrassingly large ', making the one-person expensive conveyor belt itself too large. Therefore, in practice, the multiples range from 1 to 5. Here, the number of teeth of the sprocket gear is three times the number of links forming one pedal portion. Further, a pair of guide rails 5 9 are provided for guiding and carrying the foot part 5 5. The guide rails 5 and 9 are placed so that the distance between the forward direction of the upper rail "linear portion and the" reverse "linear portion of the upper rail is the same as the pitch circle diameter of the armrest-driven chain sprocket. The number of teeth is three times the number of connecting rods of the pedal. The width of the moving surface 60 of each guide rail 59 is to bear the weight of the front wheel 56, so that the guide rail 5 9 terminates outside the armrest driving chain gear 50. With the establishment of the width 60, it is possible to prevent the armrest-driven sprocket gear 50 from interfering with the guide rail 59. In addition, the armrest-driven sprocket gear 50 is placed so that the close fitting part 70 on the forward path side and The distance between the tight-fitting portions 71 on the return path side is an integer multiple of the length of a single link of a pedal chain.

The chain 62 is driven by the armrest The handrail driving wheel 6 3 is rotated to drive the handrail belt 6 4. Although it is assumed that the shaft portion of the front wheel 5 6 of the pedal chain 5 3 meshes with the chain gear 50 and the armrest drives the chain gear 50 The tooth is partially removed (part number 5 8), due to The armrest driven chain gear 50 removes the odd-numbered teeth, so the close-fitting state of the mating parts 70, 71 on both sides cannot be invalidated simultaneously. That is, when at least one of the tight-fitting parts 70, 71 is fitted, At this time, the sprocket gear 50 does not rush, so the driving force can be transmitted accurately. Further, since a pair of guide plates is arranged on the chain 53 of the pedal portion on the opposite side of the sprocket gear 50. 8 1 can prevent the sprocket gear 50 from loosening, thereby achieving closer cooperation. Next, a second embodiment of the present invention will be described with reference to FIG. 7. The handrail driving device of the second embodiment is characterized in that two pairs of handrail driving devices in Figs. 5 and 6 are juxtaposed in order to increase the driving force of the handrail belt 64. Next, in order to avoid interference between adjacent handrail-driven sprocket gears, the distance 65 between the center portions of the individual sprocket gears 50 is set to an integer multiple of each half of the pedal portion. Therefore, the two armrest-driven sprocket gears 50 are not disengaged synchronously on the forward and return path sides, thereby obtaining a sufficiently large driving force.
