Definitions

  • ABSTRACT A variable-speed passenger transporter for con- P A er an veying passengers from a stationary surface to a belt moving at [33] non y land constant speed, which includes a plurality of rhomboid plat- 31 so/6'8 forms driven along guide means in a closed circuit along a sec- 1 tion of which the platforms are in contacting relationship to form a moving floor.
  • This invention relates to a transporter, in particular for conveying passengers, of the kind comprising a plurality of transport platforms which have parallel longitudinal edges and g which are are arranged to move over a closed circuit, common drive means for causing said platforms to move at a relatively low speed transversely to their longitudinal axis through a loading or unloading zone of said circuit and to move at a higher speed over at least one transport section of said circuit along a trajectory which is transverse to the one followed by said platforms when movingat said low speed, said circuit including at least one link section lying between said transport section and said loading or unloading zone over which the speed of each platform is brought gradually from its higher value to its lower value or vice versa, and means marking out a passageway meant to be followed by the users over the portion of the circuit lying between said loading or unloading zone and the terminal or starting end of said transport section.
  • a plurality of platforms which are initially piled up side by side, are made to come into end-to-end alignment by sliding one platform relatively to another and at the same time causing it to topple through 90 in a way similar to that of a row of books slipping along a shelf until they finally come to occupy a position in which they all lie down flat on the shelf.
  • the transporter whose platforms spread out accordionwise suffers from an additional drawback: upon moving into end-to-end alignment the initially adjacent platforms come to be moved angularly through 180 in relation to one another so that passengers, who all get on the platforms with the same orientation since they cannot anticipate the orientation that these platforms will conie to have along the transport sections, come to travel along these transport sec tions some facing the direction of movement and others with their backs turned thereto, depending on the platform on which they happen to be. Thus some passengers may arrive at the alighting deck with their backs turned thereto, thereby making it necessary for them to do a quick about turn while their platform is still moving.
  • the various platforms only form a continuous floor in the loading and unloading zones of the transporters and rapidly come to be so positioned over the remainder of their transport path as to leaveempty spaces on opposite sides of their surface, this being particularly dangerous for passengers.
  • An object of the present invention is to provide a transporter free from the drawbacks of these known arrangements.
  • a transporter of the kind set forth further comprising guide means for so guiding said platforms in their movement that each platform remains in mutual contact with its two adjacent platforms by at least part of its longitudinal edges throughout displacement along said passageway, the forward motion of said platforms,

  • FIG. 13 illustrates diagrammatically the use which can be made thereof.
  • FIGS. 14, I5, 16 and 17 show four other forms of stations including transporters according to the invention.
  • the arrangement which can be seen in FIG. 1 constitutes a loading and unloading station in a system for transporting people, at a constant speed-V, of, say, about 10 km. per hour, on two belts A and B moving in opposite directions.
  • This station comprises two similar transporters each defining a loading track, which loading tracks serve to convey people on to the belts by subjecting them to continuous acceleration along their initial portion so that their speed along the terminal part of each track may be substantially identical to the speed of travel of the belt with which it is associated, this latter speed being several times greater than the speed at which people are conveyed when they first step on to the track.
  • Each transporter device also defines an unloading track for conveying passengers stepping off belts A and B.
  • passengers are subjected to continuous deceleration whereby their initial speed which is substantially equal to the speed of travel of the belt off which they have stepped may be reduced to a very much lower speed, for example equal to the speed at which passengers are conveyed along the initial portion of a loading track, so that they may step gently on to terra firma.
  • the acceleration or deceleration to which is subjected a passenger being conveyed on a track can for examplebe such that the speed at the exit from a track may be four to five times greater than the entry speed in the case of acceleration, and from four to five times less than this entry speed in the case of deceleration.
  • the track for loading and accelerating passengers is referenced 1A in the case of the first transporter, and is referenced 1B in the case of the second transporter; correspondingly the unloading and deceleration tracks are identified 2A or 2B.
  • Tracks 1A and 2A and tracks 18 and 2B in the two transporters shown in FIG. 1 are formed by the juxtaposition of a plurality of identical platforms 3 which are driven, as will be described below, along a closed circuit, tracks 1A and 28 forming sectionsof the circuit of one transporter and tracks IB and 2A forming sections of the circuit of the other transporter.
  • the sections of these two circuits which correspond to these tracks are connected by two intermediate sections C and D in the case of the first transporter and by two intermediate sections C and D in the case of the other transporter which intermediate sections serve to lead the platforms leaving track IA or 18 to the entry of track 2B or 2A and to lead the platforms leaving track 28 or 2A to the entry of track 1A or 18.
  • the platforms must obviously be apparent along tracks 1A, 2A, 1B and 2Bto enable passengers to have access thereto, they are out of sight and preferably travelling in tunnels at a lower level when they are moving along circuit sections C C D and D
  • Tracks 1A and 1B and tracks 2A and 2B are respectively bounded, except along belts A and B, by stationary walls 4 and 5 and stationary walls 4' and 5.
  • These walls could of course be replaced by any other suitable barrier means able to prevent passengers, once they have stepped on to the tracks from leaving them except where they are meant to, or again from stepping on to these tracks at a location other than that provided for boarding.
  • Similar walls or barriers are of course also provided along the moving belts A and B and are only interrupted in the Zones where passengers are meant to step on to these belts or to step off them.
  • the speed at which the boarding and alighting tracks of the two transporters move should 'be substantially identical to the speed of movement of belts A and B.
  • the platforms 3 travelling along the tracks should preferably move at the same level as the as sociated moving belt or at a level which is only slightly lower or higher, such that passenger transfer from an acceleration track to the belt or from the belt to a deceleration track remains easy for anybody.
  • the platforms are made to follow an excluwhich is bounded by one end of the corresponding walls 4' and 5 and is so gauged as just to allow the simultaneous passage of four people, this being ensured by the provision of three partition walls 6a, 6b and 60.
  • the platforms 3 of each transporter have the shape of a generally rhomboi d quadrilateral whose longitudinal sides 3a and 3b are parallel but whose two other, shorter, sides 30 and 3d are slightly convergent thereby defining at each end of the platform two dissimilar triangular surfaces the usefulness of which will become apparent later.
  • each platform 3 is provided, on its underside in the vicinity of its obtuse angles, with a pair of downwardly projecting studs 7a carrying at their free ends rollers 7 which are respectively engaged in two channel section rails 8 and 9 extending along the entire circuit followed by the platforms.
  • These rails form not only a rolling path for the platforms defining their trajectory, but also act as 7 guide means for maintaining each platform in a given angular position, for example relativelyto the direction of travel of belts A and B, throughout displacement along the circuit.
  • rollers 10 which are pivotally,
  • rollers 11 mounted in housings 11 hollowed out in theactual sides 3a and 3b, these rollers being arranged to be slightly outstanding to facilitate any relative axial shifting to which the platforms may be subjected when in juxtaposition.
  • Each platform is coupled to its two adjacent platforms by two pairs of levers, e.g'. 11a, 11b and 12a, 12b (FIG. 2), which are pivotally connected in pairs to form heads 14; at their inner ends the levers are again connected together in pairs and to studs 13 lying at the center of gravity of each platform.
  • levers together form a jointed continuous chain K (FIG. 2) by means of which the platforms can be driven with the help of a motor (not shown) and by means of which the relative positionof the platforms can be controlled.
  • Such control is achieved by varying the angle between the outer ends of each pair of levers, such angular variation being obtained by causing the heads 14 to engage in and slide along a guide rail 15 which extends round the entire circuit to be followed by the platforms, at a set distance from the rails 8 and 9,.
  • tracks 1A, 1B, 2A and 23 do not follow a wholly straight course but are curved along the portions thereof that are bordered by walls 5 and 5' and it is along these curved portions that the previously mentioned passenger acceleration or deceleration takes place in a manner which will be described in greater detail below.
  • the axis of access to an acceleration track or ofexit from a deceleration track and the axis of travel along the portion of each acceleration or deceleration track which borders on belt A or B are therefore transversely disposed in relation to each other.
  • the opening providing access to the associated acceleration track bounded by one end of the corresponding walls 4 and 5 is of lesser width than the opening which forms the exit of the deceleration track and thereto.
  • the distance between the rollers 7 of each platform, the path followed by the rails 8 and 9 as well as the variation of their spacing, the length of the levers 11a, 11b, 12a and 12b in the chain K and the path followed by their guide rail 15 are so chosen that, along the sections of the circuit corresponding to the acceleration and deceleration tracks the platforms 3 travel along these tracks in such a way that their longitudinal axis or center line always maintains a constant orientation and forms an angle other than 0 or with the trajectory they follow when travelling at maximum speed, i.e. along sections 1 in FIG.
  • the platforms enter a track along a straight trajectory (FIG. 2) and likewise leave it along a straight trajectory but obliquely in relation to the first one, it follows that they are required to travel along a curved intermediateportion and if the platform center lines are to maintain a constant orientation throughout displacement along the track it follows that the platforms are required to carry out a relative sliding movement from left to right in FIG. 2 alongside one another as they approach a moving belt.
  • the length of these platforms and the inclination given to their side 30 relative to their longitudinal sides 3a and 3b -which inclination is equal to that of these longitudinal sides relatively to the trajectoryof the platforms along the maximum speed portion of the circuit are such that the surface of the floor formed by the platforms along a track and bounded by wall 4 or 4', to one side, and by wall 5 or 5' and the adjacent edge of the belt A or B along section I, to the other side, may in no way be discontinuous such that a passenger may, if need by, step without danger from one platform to another, even along those parts of the track where the speed of travel of the platforms is greatest.
  • each track is achieved by means common to all the platforms: it can for example be provided by a synchronous linear motor or a rack device.
  • the area allotted to each passenger arriving at the entry point of an acceleration track is indicated in FIG. 2 on the platforms by a circle p; it will be observed from an examination of the straight part I of the acceleration track, adjacent the moving belt, that the obliqueness of the platforms and their total length have moreover been so chosen that the passengers on one platform will not be inconvenienced by those .on the preceding platform when the time comes for them to step on to a moving belt. Besides they are provided with an additional intermediate surface formed by the trailing, triangular, portion of the preceding platform. The same is, of course, true in the case of a deceleration track as regards passengers stepping off a moving belt on to this track.
  • each platform has associated therewith five support uprights 16 arranged in a row along the center line of the platform on opposite sides of the circles p.
  • Each upright is engaged by its head in a cam-acting guide rail 20 which can for example extend round the whole circuit of the transporter and be arranged at different levels, depending on whether it is laid along the track-forming or operative portions of the circuit or it is laid along the other, inoperative, portions of the circuit.
  • rail 20 could be interrupted along the inoperative section of the circuit where the uprights 16 are in a retracted position.
  • rails 20 could consist, along each operative section of the circuit, of an upwardly sloping portion at the beginning of this section to bring uprights 16 to their fully projected position, of a downwardly sloping portion at the end of the operative of track-forming section to bring uprights 16 to their fully retracted position, and possibly a horizontal portion between these sloping portions to keep the upright 16 in their fully projected position throughout displacement of the platforms along this operative or track-forming section of the circuit.
  • FIG. 3 which is a sectional view of the beginning of an acceleration track-forming section taken along the second row of uprights from the right of FIG. 2 and through partition wall 60
  • the uprights 16 of each row are made successively to rise up through a longitudinal slot formed in the partition wall associated with a row until they come to project slightly above the latter at their upper ends to an extent sufficient to enable them to be grasped.
  • a passenger arriving at the point of entry of, for instance, track 1A of the transporter will simultaneously see appearing before him the platform on which he is to step and the five uprights with which this platform is provided.
  • the width of the exit from deceleration track 2A or 2B is appreciably greater than the width of the entry to acceleration track IA or 1B thereby to facilitate and speed up the unloading of passengers on to terra firma (FIG. 2).
  • the uprights 16 at the end of these tracks are made to retract rapidly by means, for instance, of the arrangement shown in FIGS. 4 to 6.
  • the floor 21 is formed with five slots 21a, 21b, 21c, 21d and 21e along the edges of which are provided overlapping sealing strips 22a and 22b which are made of resilient material and which can be locally forced apart by an upright as it progresses along the corresponding slot (FIG. 6).
  • sealing strips are so constructed and so shaped that passengers stepping off the transporter can tread thereon without any risk of their feet being caught in the slot closed off by these sealing strips.
  • each platform comprises a central panel 23 having parallel edges and rounded ends on which are pivotally mountedtwo triangular flaps 24a, and 24b able to occupy two angular positions as shown by the dash-dotted lines.
  • the platforms are-provided, like the platforms 3 previously described, with guide rollers 7 and slide rollers 10; they can be connected to each.
  • the platform construction which has just been described makes it possible to design tracks of different configurations and comprising several sections that are curved eitherway (as in the FIG. 14 arrangement) and along which these platforms can move either obliquely relatively to their axis of displacement, as along section Q in FIG. 13, or coaxially with this axis, as along section R in FIG. 13.
  • the angular positioning of the flaps 24a and 24b of each platform can conveniently be controlled by appropriately mounted guide rails engaged by rollers provided on the underside of the flaps.
  • a quadrilateral shape with oblique inclined front sides is not of course the only onethat is possible for the platforms of a transporter according to the invention. Also, the shape of the circuit followed by the platforms can. be very different from the one shown in FIG. 1 and can be adapted to suit different cases as required.
  • the deceleration and acceleration tracks are so arranged along the moving belts of a conveyor-belt passenger transport installation that a deceleration track is located ahead of an acceleration track along each belt, viewed in the direction of travel of this belt, as in the FIGS. 1 and 9 arrange ments, so that the passengers who have reached their destination canget off the belt they are travelling on before new passengers can get on. In this way any interference caused by the presence on the belt of people about to disembark will be avoided during boarding.
  • belts A and B in the FIGS. 9 and 10 construction are adjacent one another and the loading and unloading for each belt is effected along their outer edges.
  • each platform comprises, as shown in FIG. II, a main panel 25 whose left end 25a forms a triangle having two equal sides 26a and 26b symmetrically disposed in relation to the center line of the platform.
  • a main panel 25 whose left end 25a forms a triangle having two equal sides 26a and 26b symmetrically disposed in relation to the center line of the platform.
  • triangular flaps 27 and 28 whose bases 27a and 28a are in alignment with the longitudinal sides of panel 25, whose second sides are coextensive with .the sides 26a and 26b of triangle 25a and whose third sides are in alignment with side 26b, in the case of flap 27, and with side 26a, in the case of flap 28.
  • flaps 27 and 28 are not meant to be both in a horizontal position all the time, as shown in FIG. 11, that is in coplanar relationship with panel 25, and alongside beltsA and B, either one or the other is swung downwards to a vertical retracted or inoperative position, depending on the position of the platform'relative to its associated moving belt.
  • This swinging motion of the flaps can be controlled by any appropriate means as, for instance, those already described, i.e. rails and rollers, wherever it is essential to achieve correct positioning of the platforms along the circuit over which they I are required to travel while also enabling them to form a continuous surface along the operative, passenger carrying, sections of the circuit.
  • each platform viewed in FIG. I1 is cut at right angles and the length of each platform is arranged to be sufficient for the surface of the floors formed by the platforms to be continuous along both the acceleration and deceleration tracks.
  • the portion of a platform marked out in FIG. 11 by the oblique broken line m is the minimum area at that end of the platform that remains unused at any time along the acceleration track whereas in the deceleration track case it is a symmetrical portion marked out by the broken line n which corresponds to the minimum area at that end of the platform which remains unused at any time along the deceleration track, i.e. along the maximum speed sections of these tracks.
  • platforms of the FIGS, 9 and 10 construction are also equipped with vertically slidable support uprights, which are moved upwards into the operative projected position at the beginning of each acceleration or deceleration track or downwards beneath the platforms upon the latter reaching the end of these tracks.

  • FIG. 15 arrangement wherein two moving belts A and B are set relatively near to each other, is in some ways similar to the FIG. 1 construction except that provision is made for the final part of the deceleration track of each transporter to dip and to form a series of steps in order to pass underneath the moving belt with which this deceleration track is associated.
  • this last part of each deceleration track could be made to pass over the associated belt.
  • FIG. 16 a transporter arrangement which is particularly suited for a terminal station in a passenger transport system having two moving belts A and B.
  • the transporter comprises two acceleration and deceleration tracks 1A and 1B which are connected at one end by a circuit section lC of which only part is shown. At the other end tracks 1A and 1B are connected to each other as shown in FIGSv 9 and 10.
  • Passenger transporters according to the invention are not only intended to increase the speed of passengers to an extent sufficient to allow them to step without any trouble on to a moving belt oragain to enable passengers to step off this belt and subsequently reducing their speed to an extent such as to make alighting easy even for old or handicapped people, but
  • FIG. 17 can be combined, as shown in FIG. 17, with another similar transporter in order to form a single closed circuit including a first track for conveying passengers from a point A to a point B and a second track for conveying passengers from point B to point A.
