Definitions

  • the present invention relates to an access door step to a public transport vehicle, which step comprises means capable of forming a lifting platform for the disabled, in particular in a wheelchair.
  • a step of this type is described in French patent application No. 2,502,079 in the name of the ciosserie Carrier.
  • This step comprises an intermediate step between the ground and the vehicle floor, formed by the end portion of a horizontal plate housed under the floor and held in a support.
  • the platform has a capacity for horizontal translation, which allows it to be taken outwards. Once out, it can be moved vertically via its support, down to ground level, and up to floor level.
  • this device For its installation in a vehicle, this device requires a lot of free space under the floor, to admit the platform as well as its drive means in horizontal translation. On the other hand, the lifting means protrude widely above the floor. This double size is a major drawback, which greatly limits the possibility of using the device, because it does not allow its location to be envisaged in many cases, and in particular in vehicles of the urban bus type.
  • the object of the invention is to provide a step which can be transformed into a lifting platform which or, on the contrary, particularly suitable for this type of vehicle, due to the fact of being compact and housed entirely below the floor, this in order to in no way reduce the vehicle's carrying capacity.
  • a step comprising a step between ground and floor, characterized in that said step is formed by the end part of a platform whose remaining part is foldable under the floor behind the riser. upper, and in that two lifting means are associated to carry out the movements of said platform between the different levels which it must reach, ie a first lifting means secured to the chassis of the vehicle, under the floor, to ensure, by displacement of a main chassis, the transfer of the platform or step between the ground and the step level, and a second lifting means for ensuring, by displacement of a platform chassis relative to said main chassis, the transfer of the platform between the step level and the floor level.
  • the platform is formed of elongated plates hinged together so as to be foldable in accordion, one of these plates, constituting the step, being connected to means for deploying and folding the platform form, these means being movable slides on telescopic slides.
  • said first lifting means moving the main chassis is also a system of movable slides on telescopic slides.
  • a single step M of access to the floor P of the vehicle is formed by the part of a platform 1 projecting beyond the upper riser C materialized by a mixed line- end in FIG. 1.
  • the platform 1 is foldable: it comprises a plurality of elongated rectangular plates 1a to 1h, shown in the drawing by transverse reinforcing elements, and articulated together by hinges 2 allowing folding accordion plates 1a to 1f behind the riser C.
  • the 1g plate remains horizontal at all times. In the embodiment shown, it is extended outwards by the end plate 1h, articulated with it so as to be able to take a horizontal position to contribute to forming the step M, a position inclined downward to allow the '' access to platform 1 and a raised position to constitute a safety edge.
  • the platform 1 and its actuation means, ie the assembly E in FIG. 2, are mounted on a platform chassis 3 which essentially comprises two rails forming a slide 3a, two uprights 3b fixed to the rear ends of the rails 3a, and a cross member 3c between the upper ends of the uprights 3b.
  • the cross-member 3c carries by means of 3d uprights directed downwards, FIG. 3, two telescopic slides 3e parallel to the side members 3a and situated at a slightly higher level.
  • the platform 1 is hooked to the crosspiece 3c by the rear side of the plate 1a, by means of the hinges 2.
  • the horizontal plate 1g is carried by two slides 4 engaged on the slides 3e, by the intermediate of a connection assembly comprising, from the slides of the uprights 5a, longitudinal members 5b and a cross-member 5c.
  • This has a middle part offset in height with respect to two end parts to which are attached reinforcing elements of the plate 1g.
  • the two slides 4 are joined together by a cross-member 6.
  • the plate 1h extending the plate 1g forwards is pivotally movable around its axis of articulation by means of an actuating device carried by the cross-member 5c in its middle part, which device comprises two fixed slides 7 in each of which moves a slide 8 articulated to a link 9, itself articulated to a longitudinal element 10h forming part of the frame of the plate 1h .
  • the platform chassis 3 is carried by a main chassis 11, in turn carried as a console by two sliders 12 able to move on vertical slides 13 secured to chassis elements of the vehicle under the floor P. On the other apart, the slides 12 are joined by a cross member 14.
  • the chassis 11 From the slides 12, the chassis 11 comprises two short side members 11a, two uprights 11b directed downwards and, fixed to the lower ends of the latter, its support part proper, consisting of two side members 11c forming a slide.
  • the length of the uprights 11b is chosen such that the travel of the slides 12 practically reaches the upper end of the slides 13.
  • the lifting means between the main chassis 11 and the platform chassis 3 comprises, on each side, a set of two links 15, 16 articulated in scissors.
  • the front ends of the connecting rods 15, 16 are respectively articulated at the front ends of the side members 3a and 11c, while their rear ends are connected, by means of pivots 17, respectively to slides 18, 19 mounted capable of moving on the longitudinal members 11c and 3a, at least one of them being provided with drive means.
  • it is the lower slide 18 which is driving, and it is then noted, particularly in FIG. 1, that the rods 15 and 16 are slightly bent, so as to avoid any risk of bruising of their lower parts in the lower position of the system.
  • the step of the invention is as shown in FIG. 1. Its small size, both horizontally and vertically, is remarkable. Note that by providing telescopic vertical slides 13, these do not protrude downwards beyond the main chassis 11. In this position, when the vehicle door opens, the step has the same crossing characteristics as a conventional staircase.
  • the platform 1 is first deployed at the level of the step M, by lengthening the telescopic slides 3e and moving the slides 4 thereon. At the same time, the end plate 1h is lowered in the position of Fig. 4.
  • the following movement is carried out by the first lifting means, either by the slides 12 which descend on the vertical slides 13, previously deployed so that the frame 1 reaches the ground S.
  • the encounter with the ground is detected by means of a feeler 20, placed for example under the front end of the beam 11c, to provide a stop signal to the drive means of the slides 12, the descent stroke being able to vary whether or not the vehicle stops at the edge of a sidewalk.
  • Platform 1 is in position to receive a person in a wheelchair. This takes place there after crossing the plate 1h forming an access ramp, which is then raised to its safety position, FIG. 6, for example following a signal produced by a presence detector.
  • the rise of the platform 1 to the level of the floor P is carried out in two stages: first, the slides 12 go up on the slides 13, the whole finding the position of FIG. 4, with the difference that the 1h plate is raised.
  • the second lifting means comprising the links 15, 16 is deployed under the effect of the displacement of the slide 18 towards the free end of the beam 11c, while maintaining the horizontal platform throughout its action. At the end of this movement, the latter arrives at the level of the floor P, and the person in a wheelchair can then enter the bus.
  • the platform 1 In the storage phase which follows, the platform 1 is lowered to the level of the step M by returning the slides 18 to their original position. Similarly, to fold the platform 1 behind the riser C, the slides 4 retreat on the slides 3e which retract. As for the 1h end plate, it returns to the horizontal to constitute the M step with the 1g plate.
  • the platform 1 deploys first at the level of the step M, FIG. 4, and the 1h end plate is raised to the safety position.
  • the sliders 18 are actuated and the link system 15, 16 lifts the platform to the level of the floor P, so that the person in a wheelchair can take a seat there.
  • the platform then descends to the ground, first reaching the level of the step M by returning to their original position of the slides 18, then continuing by lowering the slides 12 on the slides 13.
  • the 1h plate lowers to allow the person in a wheelchair to leave the platform.
  • the slides 12 go back to the high position on the slides 13 which retract.
  • the folding of the platform 1 takes place by retraction of the slides 4 on the slides 3 which also retract, and the plate 1h returns to the horizontal position. Note that there is nothing to prevent simultaneous movements to speed up the process.
  • the normal operating cycles described above can be modified to meet the various use cases that may arise.
  • the raising or lowering of an elderly person can be facilitated by lowering and raising the step M without deploying the platform, by the sole actuation of the slides 12 on the slides 13.
