  • U.S.Cl 198/16 1gg/6lb69/l172 ABSTRACT A moving handra system for a passenger com 4 6 veyor in which the handrail has hinged edges folded under flanges of a balustrade guide member with the edges of the handrail being retained in osition by supporting plates.
  • the hinged construction provides for bending and 1,101,209 Pm ":"iw. was/ yms flexing the handrail in either direction as it passes around a drive sheave and takeup sheaves.
  • SHEET 2 [IF 2 INVi ERNEST 0, JOHN MOVING HANDRAIL SYSTEM This invention relates generally to a moving handrail and more particularly to the construction of a handrail which can be flexed in both directions with substantially the same effort and no increased wear.
  • Passenger conveyor systems whether of the moving-belt or moving-stairway type are ordinarily provided at each side with an endless moving handrail driven in synchronism with the passenger-supporting conveyor.
  • the upper run of the handrail is supported by suitable guides associated with a balustrade, and the return run and friction drive for the handrail may either be enclosed within the balustrade or located therebeneath depending on whether or not the balustrade is translucent.
  • the handrails used heretofore have had a C-shaped cross section which has permitted flexing in one direction because the edges could turn inwardly; however, flexing in the other direction has been restricted because the edges could not turn outwardly and acted as stiffening ribs to resist the flexing. Consequently, the handrails have been limited to flexing in one direction around a bend radius of approximately 60 inches as opposed to flexing in the other direction around a bend radius of approximately 12 inches. As a result of this limitation, most handrail systems have been designed with the handrail twisting in devious paths around the drive sheave and takeup sheaves to avoid flexing in the direction requiring a large bend radius. This requirement has increased the cost of the handrail system because of the additional mechanism and space required.
  • Another object of this invention is to provide a handrail system in which the handrail is retained on the guides by sup porting members which can be easily removed when it is necessary to remove and install the handrail.
  • a further object of this invention is to provide a handrail drive and takeup mechanism in which the drive and takeup sheaves have relatively small radii and are rotatable in the same plane about parallel axes.
  • a still further object of this invention is to provide a handrail having folded edges for sliding engagement with the guides of the balustrade and a central friction surface between the edges for driving engagement with a circumferential rib on a drive sheave.
  • FIG. I is a schematic side elevation view of a passenger conveyor including a preferred form of handrail system constructed in accordance with this invention.
  • FIG. 2 is an enlarged fragmentary section taken on the plane of the line 22 of FIG. I showing the construction of the handrail, balustrade, guide members and retaining members.
  • FIG. 3 is an enlarged end view taken on the plane of the line 3-3 of FIG. I showing the drive and takeup sheaves with the handrail thereon, parts being broken away.
  • FIG. 4 is an enlarged fragmentary transverse section of the drive sheave taken on the plane ofline 4-4 of FIG. l.
  • FIG. 5 is an enlarged fragmentary transverse section of the takeup sheave and handrail taken on the plane of the line 5-5 of FIG. 1.
  • FIG. 6 is an enlarged cross-sectional view of the handrail shown in FIG. 1.
  • FIG. 7 is an enlarged cross-sectional view in perspective showing the handrail with the edges spread out in the condition it is made and spliced, parts being broken away.
  • a passenger conveyor system I having a handrail 2 which is movable along a balustrade 3.
  • the handrail 2 is guided through openings in the balustrade to the driving and takeup mechanism which is desirably located beneath the balustrade thus permitting light-transmissive or transparent panels 4 to be used for the balustrade.
  • the driving of the handrail 2 may be provided by a traction drive sheave 7 which is rotatable at the same speed as the drive for the passenger conveyor belt of this system.
  • Takeup sheave 8 is located in close proximity to drive sheave 7 for rotation in the same plane P P as the plane of rotation of the drive sheave.
  • the takeup sheave 8 rotate about an axis X-X which is parallel to the axis Y-Y of the drive sheave 7. This is shown in more detail in FIG. 3.
  • the takeup sheave 8 has a shaft 9 which may be mounted in bearings 10 for movement of the takeup sheave relative to the drive sheave 7 to maintain the desired tension of the handrail when it is moved in a counterclockwise direction around the handrail system as shown in FIG. 1.
  • a second takeup sheave 11 may be mounted for rotation and tension adjustment at the other end of the balustrade 3 and is rotatable about an axis which is parallel to the axis X-X of takeup sheave 8 and axis Y-Y of drive sheave 7.
  • the second takeup sheave 11 is located in close proximity to a guide sheave I4 rotating about an axis parallel to the axis of the second takeup sheave.
  • Other guide members such as guide roller racks 15 may be located along the lower run of the handrail 2 for guiding it between guide sheave l4 and drive sheave 7.
  • the drive sheave 7 has a shaft 16 which is supported in bearings 17 mounted on a supporting structure such as angle members 18 by bolts 19 and nuts 20.
  • Shaft 16 may also be the drive shaft for the passenger conveyor belt or may be connected to that drive shaft.
  • the balustrade 3 has a longitudinal channeled support member 23 to which the transparent panels 4 may be clamped by fastening strips 24 fastened to the edges of the support member.
  • a guide member 25 on which the handrail 2 slides is secured.
  • Spaced-apart sides 26 of the guide member 25 which has a bifurcated cross section carry flange members 27 at the edges for sliding contact with the handrail 2.
  • the flange members 27 provide smooth surfaces on which the handrail 2 slides in the upper run and at the ends of the balustrade.
  • Handrail-retaining trim plate members 30 having retaining surfaces 31 extending outwardly and under the edges of the handrail 2 are supported by the support member 23 of the balustrade. Inner edges 32 of the trim member 30 are seated in grooves 33 in the sides 26 of the guide member 25. Outer edges 34 of the trim members 30 may be removably fastened to the strips 24 by a resilient snap-in connection or by screws 35. As shown in FIG. 2, the trim members 30 may be removed by removing screws 35, swinging the outer edges 34 upwardly and outwardly to displace the inner edges 32 from the grooves 33.
  • the handrail 2 is shown in the condition in which it is made and spliced.
  • the handrail may be molded of flexible material such as natural or synthetic rubber with central portion 36 connected to edge portions 39 by hinge portions 40.
  • the hinge portions 40 are of lesser thickness than the central portion 36 or edge portions 39 to provide for folding the edge portions under the central portion.
  • the handrail 2 is subjected to tension and therefore suitable longitudinal tension members which may be steel bands 41 are embedded in the central portion 36. Reinforcement of the handrail 2 in the transverse direction is provided by a reinforcing ply 42 of suitable textile material such as nylon or rayon material bonded to the handrail and extending between the edge portions 39.
  • the handrail 2 is shown in the condition with the edge portions 39 folded under the central portion 36 at the hinge portions 40.
  • Smooth sliding surfaces 43 are provided on the opposing faces of the edge portions 39 and central portion 36.
  • the edge portions 39 are spaced apart and a friction surface 46 is molded or cut in the face of the central portion 36 which is exposed between the edge portions 39.
  • the handrail 2 is shown with the sliding surfaces 43 in sliding contact with the flange members 27 while the friction surface 46 is held out of engagement with any part of the guide member 25.
  • the handrail 2 is shown in engagement with the drive sheave 7 which has a circumferential rib member 47 for engagement with the friction surface 46 of the handrail.
  • the rib member 47 preferably has a thickness greater than the thickness of the edge portions 39 to provide the desired frictional engagement between the rib member 47 and handrail 2.
  • the rib member 47 may have a friction surface 48 machined or ground therein for engagement with the friction surface 46 of the handrail 2.
  • the outer surface which is normally grasped by passengers in the upper run will engage the sheave and the handrail will be flexed in one direction as shown in FIG. 5. Then as the handrail 2 passes over the traction drive sheave 7 the friction surface 46 and the edge portion 39 will engage the sheave flexing the handrail in the other direction. In either case because of the hinged construction, the resistance to bending and flexing is kept at a minimum. As illustrated in FIG. 3, the radius about which the handrail 2 passes maybe relatively small as compared to the thickness of the handrail.
  • the radius R of the drive sheave 7 and the takeup sheave 8 is not more than l times the folded thickness T of the handrail 2 so that the drive and takeup mechanism can be installed in a relatively small space.
  • This also applies to the radii of the second takeup sheave l1 and the idler guide sheave 14. It can be seen from FIG. I that the outer surface of the handrail 2 engages the second takeup sheave 11 and the edge portions 39 engage the idler guide sheave 14.
  • one of the edge portions 39 is folded at one of the hinge portions 40 and inserted between one of the flange members 27 and an opposing retaining surface 31 of the handrail-retaining trim member at one side of the balustrade.
  • the handrailretaining trim member 30 is removed by disengaging screws and moving the outer edge 34 upwardly and outwardly so that the inner edge 32 can be removed from the groove 33 in the side 26 of the guide member 25.
  • the other edge portion 39 may than be folded at the other hinge portion 40 to a position under the other flange member 27.
  • the trim member 30 is then inserted under the edge portion 39 with the inner edge 32 in groove 33 so that the retaining surface 31 engages the edge portion 39 of the handrail 2.
  • the trim member 30 is then fastened to the fastening strip 24 by screws 35 and the handrail is ready for operation.
  • the sliding surfaces 43 of the handrail 2 engage the flange members 27 as it passes over the balustrade in the upper run and the retaining surfaces 31 of the trim members 30 positively hold the handrail in place on the guide member 25.
  • the takeup sheave 8 In the lower run of the handrail 2 it passes over the takeup sheave 8, drive sheave 7, second takeup sheave II and idler guide sheave l4 flexing in both directions with a minimum of resistance and wear.
  • a handrail for passenger conveyors comprising an elongated body of flexible material having a central portion with longitudinal edges for grasping by passengers, edge portions underlying said central portion and fold under flanges of a guide member, hinge portions connecting said central and edge portions at said longitudinal edges, said hinge portions having greater transverse flexibility than said central portion and said edge portions to facilitate folding said edge portions under said flanges of a guide member and producing a minimum resistance to bending of the handrail in both directions around sheaves of a driving and guiding system.
  • a handrail and guide mechanism for a passenger conveyor system comprising an elongated body of flexible material, support means for supporting and guiding said body, said elongated body having a central portion, edge portions, hinge portions connecting said central and said edge portions and having greater transverse flexibility than said central portion and said edge portions to facilitate folding of said edge portions under said central portion, flange members mounted on said support means and extending outwardly between said folded edge portions and said central portion and handrailretaining means mounted on said support means under said edge portions to retain said edge portions in the turned-under condition between said flange members and said retaining mean.
