- the elements of the translation system are advantageously: - partly housed in a front casing 3 secured to the rotary plate 7, for example the winch device 21 of the cables or traction straps 25 for translating the box, the other sliding elements and arms 15a 15b, located under the box, this casing 3, being profiled to form an aerodynamic deflector during transport of the box.
- FIG. 4 is a view similar to FIG. 3, the box being turned 90 ° for translation
- FIG. 5a and 5b show in two views, respectively in plan and side view of the elevation system of the slides for the horizontal translation of the box and
- FIG. 6a and 6b show the device in a translational position of the box and therefore of the chair on an equipped vehicle.
- the lifting device essentially consists of a rectangular parallelepiped box 1, a front casing 3, a support frame 5, a plate 7 rotatably mounted on the chassis 5 and a translation system 9 of the box 1.
- the box 1 is intended to accommodate a wheelchair for disabled person in a folded position.
- the casing 3 houses the front part of the translation system of the box.
- the support frame 5 is in the form of a rectangular frame about 0.80 m wide and 1.20 m long, made up of tubular section 11 of square section.
- This chassis is mounted fixed on the roof bars 13 of the vehicle to be equipped, which is conventionally adapted for driving by disabled people, in particular the lower limbs.
- the rotary plate 7 is a rectangular plate, of dimensions slightly smaller than those of the chassis. It supports the front housing which is fixed on its front part, the box and the translation system of the box.
- the translation system intended to move the box from a lower position close to the ground to a higher position on the vehicle roof, is made up of sliding elements 15 housed between the box and the turntable and of traction elements 17 proper 5 housed in the front housing.
- sliding elements 15a arranged longitudinally and substantially on the middle part on the plate, comprise first elements 15a intended to ensure the horizontal translation of the box and second elements 15b supporting the box connected to the traction element and intended to form the elements 0 of the aforementioned vertical arms for the vertical translation of the box.
- the second sliding elements 15b are mounted for this purpose, pivoting on an intermediate carriage 19 guided in rotation in the first sliding elements.
- the traction element consists of a winch 21 and its actuating motor 3 23, provided with two lateral cables 25 connected to the upper return piece 27 of the second sliding elements.
- the return piece allows you to check the tilting of the box in its transition to its vertical displacement.
- the assembly has symmetry with respect to a median longitudinal vertical plane, and the two cables 25 allow good control of the vertical translation of the box.
- the device comprises a device for controlling all the motor elements (not shown) for rotating the plate and translating the box, mounted on the dashboard and capable of being controlled by a disabled person.
- the drive mechanism for the turntable 7 appears in FIGS. 3 and 4.
- the turntable is rotatably mounted in the plane of the frame of the chassis 5 at a short distance from the latter along a pivot axis 29 located slightly behind the '' a median transverse plane of the frame.
- This axis is mounted on an internal tab 31 fixed to the frame, a short distance from the profile on the driver's side of the vehicle.
- the plate is supported parallel to the plane of the frame by a set of rollers 33 suitably oriented to accompany the rotation of the plate.
- two rollers are arranged fixed to the frame substantially, at the rear of the pivot axis 29, a third is located on the front part of the frame and a fourth in the angle opposite to the first two rollers at the rear part of the frame. frame.
- rollers 33 are mounted in the plane of the frame on lugs 35 integral with the latter.
- the mechanism for driving the plate in rotation comprises a chain 37 connected to a fixed point 39 on the front left corner and to a tensioning axis 41 biased by spring towards the rear.
- This chain 37 meshes with a pinion 43 driven in rotation for a motor 45 fixed to the upper part of the plate.
- the gear coupling is achieved by means of two rollers 47 arranged on each side of the pinion 43 at its base and under which the chain passes by winding around the pinion.
- the rotation takes place over the width of the chain, from a transport position fig 2 where the plate is in the axis of the frame (zero angle of rotation) to a transverse translation position fig 4, at right angles to the position transport.
- the drive is interrupted by conventionally placed limit switches 49, allowing rotation to stop at these two limit positions, longitudinal transport and transverse translation.
- This contact is for example disposed on the front middle part of the plate, 5 cooperating with an additional element initiating the stop, respectively in front of the front lug 35 of the third caster for stopping in the position of transport and of the tab 35 of the rear angle of the fourth caster and of the chain tension axis for stopping in the translation position.
- the first slide elements 15a pivotally mounted at their outer end on the plate are raised at their internal end, at the end of the transverse rotation stroke of the plate, this by means of a simple cable 51 connected by the 'one of its ends to the frame and by its other end to the slide element via a return of two pulleys ' 53, one of which is raised by 15-20 cm in the front casing.
- the cable tightens and raises the end of the slide to the high pulley at the end of the stroke.
- the slide element is then oriented downwards, which automatically moves the carriage 19 supports inside the slides 15a and therefore the box.
- the second slide element 15b pivots on the carriage under the control of the pulling cables which are elongated. They then move to a vertical position along the side of the vehicle and the box can then descend along the vertical arm elements formed, as shown in FIG. 6a and 6b.
