Definitions

  • the present invention relates to a mobile platform by means of which disabled persons may board and alight from vehicles, and in particular railway carriages.
  • the object of the present invention is to embody a platform that will provide for the ascent and descent of disabled persons into and from railway carriages, exhibiting a structure such as requires no alteration to the architecture of the carriage, and featuring simple, safe operation.
  • the stated object is achieved in a mobile platform as characterized in the appended claims, which consists essentially in a central frame slidably supported by two beams fixed permanently to the chassis of a railway carriage.
  • the central frame is set in motion by relative drive means, and capable of movement transversely to the longitudinal axis of the chassis in such a way as to extend on either side through one of the two doorways afforded by the carriage.
  • the central frame is also provided with a pair of decks to support a wheelchair, which lie on opposite sides in a common plane and are power driven independently by belt means in such a way as to manoeuvre vertically, when the central frame is extended from the carriage, between a position of alignment with the frame and a lowered position substantially level with the trackside pedestrian surface.
  • the present invention sets forth a compact unit comprising all such elements as are necessary to enable a disabled person's boarding and/or alighting from a railway carriage, which can be fitted in its entirety to the vestibule of the carriage without any need for prior modification, and operated thus safely and faultlessly.
  • the mobile platform according to the invention is intended for use in conjunction especially with a railway carriage (illustrated schematically in figs 1 and 7); the carriage consists essentially in a fixed chassis 1 affording a first floor level 1a that coincides with vestibule areas located one at each end. Each such end area of the carriage affords two doorways, denoted 2a and 2b in fig 1, positioned opposite one another, by way of which passengers can enter the carriage or alight onto a trackside area 3 lying at a height H lower than the first floor level 1a of the carriage.
  • the railway carriage is of a type designed with two floor levels, the higher level being reached by way of a flight of steps GR of which the individual height is denoted G1; needless to say, however, the essential concept of the present invention is by no means limited to any one type of carriage.
  • the platform comprises essentially two principal components, namely: a horizontally traversing central frame 4, and a pair of decks 7 capable of vertical movement independently of the central frame 4. More exactly, the central frame 4 (figs 1 and 2) is positioned at the first floor level 1a and serves in its turn to establish a second floor level 1b set at a height G greater than that of the first and creating a full step, preferably equal to the height G1 of the carriage steps GR.
  • the central frame 4 runs across the carriage and is carried slidably between a pair of fixed beams 5a and 5b (hollow sections, for example, of which one only 5a is visible in fig 2) rigidly associated with the first floor level 1a.
  • FIG. 6 denotes drive means housed between the two floor levels 1a and lb, by which the central frame 4 can be traversed horizontally in either direction F (see figs 1 and 8) between a non-operative limit position (not illustrated), in which the frame 4 simply constitutes the second floor level 1b, and an operative position in which the frame projects a given distance externally of a relative doorway 2a or 2b.
  • drive means 6 for the central frame 4 comprise a first vertical shaft 12 driven by a first geared motor 45 positioned substantially to coincide with the transverse axis X of the frame 4, and a timing pulley 12p keyed to the shaft 12 and flanked by idle tension pulleys 13; a timing belt 14 is looped around the keyed pulley 12p, over the idle tension pulleys 13 and around two second timing pulleys 15 disposed symmetrically one on either side of the transverse axis X of the central frame 4.
  • Each such second pulley 15 is keyed in turn to a respective second vertical shaft 16 the central part of which carries a keyed gear 17 meshing with a further gear denoted 17a, which in turn meshes with a horizontal rack 18 secured to the side of the central frame 4.
  • the rack 18 is provided with travel limiting means denoted 50 in fig 1, which are designed to stop the frame 4 in either of the two aforementioned limit positions, and fitted to the sides of the frame 4 at points which coincide substantially with the transverse axis X of the frame when the frame is in the non-operative position, and at all events, in such a way at least as to ensure complete extension of either deck 7 before the traversing movement of the frame ceases.
  • the travel limiting means 50 themselves are operated by contact with or striking against a corresponding transducer or cam mounted to the fixed beam 5a (operation of the limiter may be mechanical, optical or electric depending on whether the platform drive system is electric or pneumatic).
  • the decks 7 serve to accommodate the wheelchair 9 of a disabled person boarding or alighting, and are located one at each end of the frame 4, disposed symmetrically in relation to the transverse axis X.
  • Each deck 7 constitutes an integral part of the frame, and incorporates means 8 by which to ensure stable positioning of the wheels 9a of the chair 9.
  • Such means 8 consist in a pair of quadrangular recesses 19 (see fig 3) afforded by the internal area of each deck 7, each recess in turn affording a matching plate 19a that serves both as a cover and as a support for the relative wheel 9a.
  • the single plate 19a is capable of movement (in the direction of the arrow denoted F1 in fig 3) between a raised, at-rest position of alignment with the plane of the deck 7, in which the recess 19 is covered, and a lowered working position assumed when occupied by the wheel 9a of a chair, in which the plate 19a descends fully into and settles on the bottom 19f of the recess 19.
  • Each plate 19a is provided with travel limiting means 20 associated with its underside and consisting in a pair of arms or lugs 20a, fixed at right angles to the plate itself and carrying a roller 35 at bottom that is rotatable about its own axis and designed to bring about the return of the plate 19a to the at-rest position when the deck 7 is in a lowered position (shortly to be illustrated), and also upon passage of the central frame 4 from the operative to the non-operative position.
  • the latter repositioning manoeuvre occurs through contact of the roller 35 with a corresponding stop or distance rail 36 that is part angled and rigidly associated with the chassis 1 of the carriage.
  • each plate 19a Also associated with the underside of each plate 19a are three U-shaped supporting arms 60 (see figs 3 and 4), disposed parallel one with another and anchored at their respective ends to the internal area of the plate and to the internal area of the deck 7 in the manner of an articulated parallelogram linkage, by which the plate 19a is kept in alignment with and parallel to the remainder of the deck 7 throughout the various stages of its movement.
  • the supporting arms 60 naturally will be of depth and position so as not to interfere with the limit roller 35.
  • the two decks 7 are capable of movement not only independently of the central frame 4, as mentioned above, but also of one another; this facility is provided by belt drive means 10 housed within the central frame 4 and operating on both sides of each deck 7 in such a way as to enable movement in a vertical direction, with the frame 4 occupying the operative position needless to say, between two limit positions: elevated, in which the deck 7 occupies the same plane as the central frame 4, and lowered, with the deck 7 on a level substantially corresponding to that of the trackside 3.
  • the single deck 7 comprises two parallel side members 7a each lying adjacent to the central frame 4 and partially accommodating the belt drive means 10, which are capable of vertical movement between the elevated and lowered limit positions aforesaid.
  • the area between the side members 7a is occupied by a table 7b that supports the wheels 9a of the chair 9 and is likewise capable of movement between two limit positions derived from the belt drive means 10, though only with the side members 7a in the lowered position: a raised non-operative position, whereby the table 7b is distanced from the trackside surface 3 at a height substantially equal to that of the side members 7a, and a lowered operative position in which the table 7b is set down effectively on the trackside surface in such a way that a wheelchair 9 can roll onto or off the platform.
  • Further travel limiting means 53 located between the table 7b and the side members 7a permit of locking the belt drive means 10 once the deck has reached the lowered limit position.
  • belt drive means 10 that comprise a pair of first pulleys 21 and 21a, mounted laterally between the end of the side member 7a innermost in relation to the central frame 4, and the fixed beams 5a and 5b, and keyed to a horizontal shaft 22 driven by a corresponding second motor 46.
  • first pulleys 21 and 21a are paired with respective belts 23 and 23a of which the former extends parallel to the side member 7a from the relative first pulley 21 to the projecting end of the side member, and the latter runs perpendicular from the corresponding first pulley 21a to the innermost end of the side member 7a; each belt 23 and 23a is anchored at one end to the relative first pulley 21 and 21a and at the remaining end to a respective second pulley 24 and 24a permanently associated with the deck 7, passing additionally around a set of intermediate third pulleys 25s, of which one denoted 25 is capable of movement internally of a relative vertical channel 25a in the side member 7a and permanently associated with the table 7b.
  • the third pulleys 25s serve to keep the belts tensioned with the deck 7 occupying either of the elevated or lowered limit positions.
  • 51 denotes travel limiting means fitted to the innermost edge of each table 7b (such means may also be of different type depending on the drive system adopted), which interact with a relative transducer or receiver 52 fitted to the central frame 4 and serve to lock the belts 23 and 23a, hence the deck 7, on arrival at the elevated limit position.
  • each deck 7 is in fact equipped with a relative motor 46 and a pair of belts 23-23a along each longitudinal flank, as fig 1 clearly illustrates; to occasion the movement of the matching pair of belts 23 and 23a located on the longitudinal side of the deck 7 opposite from the motor, the end of the horizontal drive shaft 22 adjacent to the table 7b is fitted with a gear 26 in mesh with a further gear 27, this in its turn integral with a transmission shaft 28 mounted rotatably to and passing transversely through the central frame 4 to connect at the far end, by way of a third gear (not illustrated, being identical to that denoted 27) with an identical assembly comprising gear 26, horizontal shaft 22 and first pulleys 21 and 21a, in such a way as to synchronize the movements of the four belts 23 and 23a in elevating and lowering the deck 7.
  • each pantograph 30 denotes vertical guide means associated with the two sides of each deck 7, which serve to keep the decks parallel with the trackside surface 3 when manoeuvring from one limit position to the other.
  • such guide means 11 consist in a pantograph 30 associated with each longitudinal flank of the single deck 7, housed internally of the corresponding side member 7a and anchored by its ends to the central frame 4 and the side member itself, respectively.
  • each such pantograph 30 is capable of movement in the usual manner, the end anchored to the side member 7a being slidable in a relative slot 30a afforded by the side member itself, between two limit positions of minimum and maximum extension which coincide with the limit positions of the deck 7.
  • each table 7b carries a hinged ramp 32, freely rotatable about a pivot denoted 32d and extending across the entire breadth of the table.
  • the ramp 32 is also supported from beneath, at each end or thereabouts, by a jacking strut 33 freely connected at one end 33a to the crank arm 34a of an operating lever 34 disposed parallel with the strut and pivoted at mid-point to the side member 7a; this same operating lever 34 is also anchored rotatably at one end 34b to the aforementioned moving third pulley 25, which lies alongside the outermost end of the side member 7a.
  • the jacking strut 33 is also made to slide in a substantially horizontal direction through a hole 33f fashioned in the fascia of the table 7b.
  • the ramp 32 can be angled between a non-operative position, adopted in the elevated position of the table 7b, in which the face of the ramp is disposed at right angles to the table and the strut 33 distanced from the ramp, and an operative position coinciding with the lowered position of the table, in which the ramp is disposed at an angle denoted ⁇ in relation to the table (fig 5b) and the strut 33 motioned forward against its underside by rotation of the operating lever 34.
  • each side member 7a is fitted with a boot 38 anchored by its ends to the central frame 4, and to the member itself (figs 4, 5... and 8); added protection is afforded laterally of the side member 7a by a first cloth denoted 39, which unwinds from a parallel first roller 39a accommodated internally of the central frame 4.
  • the boot 38 and the cloths 39 ensure that the belt drive means 10 and the guide means 11 remain protected during passage of the deck 7 from the elevated position to the lowered position.
  • a second cloth 40 associated with the innermost edge of the table 7b (see figs 3 and 4), anchored by one end to a corresponding second roller 40a mounted rotatably to the table itself, and to the central frame 4 at its remaining end, serves to cover the rear part of the table 7b during passage between the limit positions of the deck 7.
  • Each deck 7 incorporates a mechanical device that will lock the pantograph 30 in the event of belt failure, and is caused to operate whenever the belts 23 and 23a may register insufficient tension; as discernible in fig 6, in fact, one of the moving third pulleys 25 (that denoted 25b), is mounted so as to oscillate in the manner of a jockey, tensioned into a lowered operative position by the action of the respective belt 23 and 23 against a spring (not illustrated), and connected to one respective end of a double lever 55 accommodated within each side member 7a.
  • the two sections of the double lever 55 which are capable of reciprocating horizontally, project from the respective ends of the relative member 7a and are interconnected by a rocker arm 56 pivotably mounted at centre to the side member 7a.
  • the rocker arm 56 is located to coincide with the end of a locking rod 57 pivoted likewise at one end to the side member 7a, which affords a set of teeth 57a offered to a matching set of teeth 58 associated with the moving end of the relative pantograph 30.
  • the system by which the central frame is driven (rack and pinion) will be connected to manually operated release levers consisting, for example, in a flexible linkage 99 connecting with each of the doorways 2a and 2b (see fig 1).
  • the linkage could be operated through a suitably located flap, for example, so as to release the clutch (permanently coupled) of the first motor 45 and allow the central frame to be pushed back to the inboard position by hand.
  • a disabled person confined to a wheelchair can be afforded access to and from a railway carriage in the following manner.
  • the railways attendant will be stationed alongside a set of push buttons 47 mounted to the exterior of the carriage and providing control over the various movements of the platform, whilst the wheelchair 9 is moved onto the deck 7 nearest the doorway at the trackside 3 (that denoted 2a in the example of figs 1 and 8) with its wheels 9a planted squarely on the recess plates 19a.
  • the attendant now operates the first motor 45 to traverse the central frame 4 through the doorway 2a to the point where it projects from the carriage at least far enough to bring the deck 7 fully out of the vestibule (as illustrated in fig 1).
  • the plates 19a will be lowered by the action of the rollers 35 which, no longer afforded support by the distance rails 36, allow each plate to drop under its own weight and settle on the bottom 19f of the relative recess 19.
  • the jacking rods 33 are rotated by the relative third pulleys 25b, and the ramp 32 swings through the angle ⁇ whereby it is brought into the operative position of fig 5b.
  • a platform thus structured affords certain notable advantages: the assembly of central frame, decks and beams (including the relative drive and travel limiting means, needless to say), forms a single unit complete with means, denoted 41 in fig 1, for fastening to the first floor level 1a; such a unit can be fully integrated into the existing carriage floor (see figs 7 and 8 in particular), and its inclusion results in one part of the vestibule area being raised by an amount preferably equal to the height G1 of the adjacent passenger steps GR.
  • the unit is especially robust, capable of withstanding the everyday traffic of passengers descending via the vestibule onto the trackside, and creates no visible obstacle that might obstruct their passage.
