Definitions
- the present invention relates to a device for assisting the crossing of one or more steps or a threshold by a vehicle, in particular for persons with reduced mobility who move by means of a wheelchair, or for people moving a wheeled cart for the transportation of objects.
- Such a threshold has a height generally from one to several tens of centimeters and is an obstacle often impassable for a person with reduced mobility or delivery carts.
- One solution to allow the crossing of such a step by a vehicle or wheeled trolley is to set up an access ramp.
- a major constraint on the implementation of such a ramp is a lack of permanent encroachment on public roads, sidewalks and / or roadways, passageways, etc.
- retractable retractable ramp systems are known inside a box frame intended to be installed in the thickness of the step to be crossed.
- the ramp is housed inside said frame (or box) and is deployed in a direction substantially normal to the step to be crossed.
- Such a device is described, for example, in the document FR 2 947 224, in the name of the applicant.
- a major concern of the plaintiff is to ensure a discreet integration of its device and to best preserve the aesthetics of the place.
- the device is then covered with an additional thickness of soil, which thickness can reach several centimeters in the case of certain materials, in particular a marble slab or a stone cladding.
- the retractable ramp is generally deployed in the upper limit of the frame and reaches the maximum substantially at an upper surface of said frame.
- the additional floor covering therefore causes the presence of a projection which constitutes an additional obstacle for the vehicle.
- the plaintiff sought to facilitate the crossing.
- the present invention proposes for this purpose a device for assisting the crossing of an obstacle by a wheeled vehicle, particularly for persons with reduced mobility.
- the device is characterized in that it comprises a stationary frame and at least one extendable ramp according to an extraction stroke between a position retracted inside said frame and a position deployed outside said frame, said ramp having one end low end intended to abut against a ground and an opposite high end, the upper end being mechanically connected to at least one ramp lift lever, activatable by the movement of the ramp, causing an elevation of the upper end of said ramp on a portion of extraction end-stop, said lift lever being realized in the form of at least one foot pivotally mounted on the ramp between an inactive folded position, and an end position in which said foot supports at least in part the weight of the upper end of said ramp, said foot being elevating on a race portion adjacent to the final position.
- close to the final position is meant a running portion located closer to the final deployed position of the foot than the inactive folded position of said foot.
- said foot becomes elevated from its contact with the ground.
- the race portion close to the final position then refers to the portion of the race situated between the moment the foot makes contact with the ground and the moment when the foot reaches its final position.
- a movement of extraction of the ramp is transformed into a movement having a vertical component to raise the ramp. high end of said ramp.
- a single driving movement then makes it possible both to extract the ramp substantially horizontally and to raise the high end of the ramp.
- the upper end of the ramp can be raised up to, if necessary, exceed the upper limit of the frame and level with a floor covering, or at least approaching it to minimize the jump.
- the amplitude of the lever movement is determined according to the final height to be achieved.
- the lift lever in the form of a foot resting on the ground ensures a solid support of the ramp.
- the lever foot is in a substantially vertical position for optimal support of the ramp and the vehicle to take it.
- the device comprises at least one retaining link capable of being locked in translation relative to the frame at one end and at the foot by an opposite end located at a distance from the pivot point of said foot, said retaining link. ensuring the deployment of said foot and maintaining it in support against the lower ground on the end of extraction stroke portion.
- the retaining link may, for example, be attached substantially mid-height or one-third of said foot.
- the foot is pivotally mounted against at least one elastic return member of the spiral spring type, tending to bring it back to the folded position.
- the elastic return member thus ensures the return of the foot to its inactive folded position when storing the ramp, in particular in response to the release or release of the retaining link.
- the elevator foot forms a main lift lever and the device comprises at least one secondary lift lever in the form of at least one inclined connecting rod comprising a first end mechanically linked to the upper end of the ramp and a second end guided inside the frame and maintained at a height less than the height of the first end, said connecting rod coming on a portion of the end of extraction stroke, bearing on a return piece mounted in the frame and causing a raising of the first end of the connecting rod and, consequently, of the upper end of the ramp.
- an inclined connecting rod allows for a guide ramp ensuring the raising of the upper end of the ramp when said inclined piece is forced against the return piece.
- the return piece is a pad having an inclined contact surface.
- the return piece is a wheel.
- Advantageously complementary to the ramp has a portion of extraction stroke preceding the end of stroke portion ensuring the elevation, and wherein said ramp is adapted to come to rest on the wheel.
- the wheel has a dual support function facilitating the extraction of the boom and return part when interacting with the inclined rod.
- the first end of the rod is pivotally connected to the ramp and in that the second end of the rod is connected to a pivotally guide member.
- the first end of the connecting rod is connected to the ramp by a double ball joint, and in that the second end of the connecting rod is connected to a guide element by a double ball joint.
- Such links allow to accommodate the relative movements, including the change of inclination, between the ramp and the connecting rod during deployment or retraction.
- connection of the connecting rod on the ramp coincides substantially with a pivot axis of pivoting of the elevator foot.
- the transmission and the recovery of efforts by the foot are thus optimized.
- the secondary lift lever is activated before the elevator foot.
- the lift lever connecting rod thus makes it possible to start raising the ramp before the foot, forming the main lift lever, is activated.
- the device comprises at least one handle intended to allow manual drive of the ramp.
- the device comprises at least one drive motor mounted on at least one drive carriage connected to a connecting rod of the ramp and associated with a rack in the frame.
- the inclined rod forming a secondary lever may advantageously be linked to the drive carriage serving as a guide means for said rod.
- a single driving movement makes it possible both to extract the ramp substantially horizontally and to raise the high end of the ramp.
- the pulling movement for extracting the ramp will also allow the high end to be raised at the end of the deployment stroke.
- the device In the case of a motorized drive, the device allows the implementation of a single engine, which has significant advantages in terms of cost, weight, and control of the device.
- the device comprises a maintenance slide supporting at least the guide rails of the ramp.

Each rail extends over a major part of the length of the drawer 1 10 and has a profile cooperating with lateral bearings (not visible) of the ramp 2. Each rail 1 5 may include a C-shaped profile (as shown), L or U, for example.
- Each rail 1 5 has an open front end for releasing the ramp of the rail 1 5.
- Each rail 1 5 also has a rear end which can advantageously be closed and thus constitute a stop at the end of the storage stroke.
- Figures 4a, 4b, and corresponding Figures 5a, 5b show an initial phase of deployment of the ramp 2.
- the ramp 2 is deployed substantially rectilinear manner.
- the lower end 21 of the ramp 2 slides or rolls on the lower ground 3 while the upper end 21 translates along the guide rails 1 5 substantially halfway up the frame 1 0.
- the device 1 shown implements two mechanisms of complementary levers levers. Each mechanism can, however, possibly be implemented independently.
- a first lever mechanism comprises a foot 24, pivotally mounted on the ramp 2, close to the upper end 22, between an inactive folded position and an extended position in which said foot is held in abutment against the lower ground 3.
- the foot 24, bearing against the lower ground 3 before its end of travel (FIGS. 4e, 5e), then constitutes a lever causing the elevation of the opposite end of said foot 24, and consequently of the end 22 high, ramp 2.
- the foot 24 is deployed and held in abutment by a retaining link 40 held in the frame 10 and able to be locked in translation in said frame 10 by one of its ends.
- the foot 24 is also mounted against an elastic return means, for example a spring 41, in particular spiral, tending to return to the folded position.
- the spring 41 works in tension.
- the spring 41 is attached by a first end to the foot 24 and a second end opposite the ramp 2.
- the spring 41 is attached to the foot 24 at one end of said foot 41 opposite the point of pivoting of said foot 24 on the ramp 2.
- the second end of the spring 41 is attached to the ramp 2 downstream of the pivot point of the foot 24 on the ramp 2, towards the lower end 21 of said ramp 2.
- the retaining link 40 is in the form of an arm having a first end pivotally attached to the foot 24, away from its pivot point on the ramp 2, and having a second end moving on the bottom 1 1 2 of the drawer 1 10 of the chassis 10.
- the second end is equipped with a wheel 44.
- the retaining function is implemented by a stop 43 disposed at the front of said frame 10.
- the abutment 43 comprises a sheet rim.
- the abutment 43 is mounted on the bottom wall 1 1 2 of the drawer 1 10.
- the stop 43 ensures the locking in translation of the retaining link 40 and consequently allows the deployment of the foot 24 and its support against the ground lower on the end-of-stroke extraction portion.
- the operation of the first lever mechanism is as follows.
- the foot 24 in a substantially horizontal direction, the foot 24 remains held folded against a lower surface of the ramp 2 by its spring 41.
- the retaining link 40 is pulled by the movement of the ramp 2 and moves along the bottom 1 1 2 until its second end meets the stop 43 ( Figure 4d, Figure 5d).
- the upper end 22 of the ramp is extracted substantially at height of the guide rail 1 5 as initially.
- the end 22 of the ramp 2 is raised until the foot 24 is substantially perpendicular to the lower ground 3 ( Figures 4f, 5f) and the ramp 2, which is the final position of said foot 24.
- a stop (not visible) ensures stopping of the pivoting of the foot 24.
- the extraction is stopped concomitantly, for example by a corresponding abutment means (electronic stop engine 1 7 by determining the distance traveled, for example using a turn or resolver account).
- the bearing amplitude of the upper end 22 depends in particular on the length of the foot 24 and its point of articulation (pivoting) to the ramp 2.
- the length of the foot 24 is adjustable. Such a setting will also allow to take into account the devers and irregularities of the lower ground 3 if necessary.
- said foot 24 may be equipped with a sliding shoe, or even a terminal wheel.
- the ramp 2 may comprise a plurality of feet 24 distributed over the width of said ramp.
- Each half-ramp 2a, 2b is here equipped with two lateral feet 24.
- feet 24 taking support on the ground makes it possible to ensure a solid support of the ramp 2 once deployed.
- the foot 24 is in a substantially vertical position for optimal support of the ramp 2 and the vehicle to take it.
- the axis of pivoting of the foot 24 coincides with a point of attachment of the connecting rod 1 72 to the upper end 22 of the ramp 2.
- Such a configuration makes it possible to further improve the recovery and the transmission of forces. ramp stability and lightening of the structure.
- this mechanism follows the following inverse steps.
- the return of the ramp 2 towards the inside of the frame 10 causes the foot 24 to return to its folded position under the action of the spring 41.
- the retaining link 40 is held against its stop 43 until the foot 24 reaches its inactive folded position and then the retaining link 40 follows the ramp 2 towards the rear of the chassis 1 0.
- the folding of the foot 24 also allows the lowering, by gravity, of the upper end 22 of the ramp 2.
- the ramp 2 is reengaged in the support rails and guide 1 5 and brought back (manually or by the engine 1 7) inside the frame 1 0.
- the retaining link is made in the form of a strap or rope fixed in a wall of the frame 10, in particular the rear wall 1 1 3c of the drawer 1 10.
- said restraint link may be associated with a winder ensuring its automatic winding as the relaxation of the restraint link.
- a second lever mechanism is achieved by the inclined rod 722.
- the connecting rod 1 72 has a first end, high, linked to the ramp 2 and a second end, low, mechanically linked to the carriage 1 71 and maintained at a height less than the height of the first end.
- the second end of the inclined connecting rod 722 is kept substantially fixed in elevation with respect to the frame 10.
- the rod 1 72 inclined is intended to come on the end of extraction stroke portion, bearing against a return piece mounted in the frame 10 and causing the raising of the first end of said inclined rod, and by way of consequently, from the upper end 22 of the ramp.
- the support of the link 1 72 against the return piece is effected via a contact surface formed by the bottom wall 1 72a and the extension 1 72c of said rod 1 72.
- the inclined rod 722 constitutes a lever when it bears against a wheel 19 fixed in the chassis 10 near the front face of extraction of the ramp 2.
- the connecting rod 1 72 has a dual function, namely a drive function of the ramp 2 and a function of raising the ramp on the end of race portion considered.
- the wheel 1 9 can serve to facilitate the extraction of the ramp 2.
- Said wheel 1 9 also has a dual function, namely a support function of the ramp 2 during a first portion extraction of the ramp and a lift lever function on the end of stroke portion considered.
- the link 1 72 comes into contact against the wheel 1 9 ( Figures 4c, 5c) which then acts as a return part.
- the contact of the connecting rod 1 72 with the wheel 1 9 is effected first through the extension 1 72c and then through the bottom wall 1 72a.
- the end of the rod 1 72 connected to the drive carriage 1 71 being fixed in elevation relative to the frame 10, any subsequent extraction movement (manual or by the engine 1 7) forces the rod 1 72 against the wheel 1 9 and causes the increase of its inclination ( Figures 4d, 4e, 4f and 5d, 5e, 5f). This results in a relative elevation of its opposite end, and consequently in the upper end 22 of the ramp 2.
- the amplitude of the elevation is determined by the total length of the link 1 72 and its maximum inclination.
- the ramp is locked in position (engine 1 7 stopped and blocked, blocking by the foot 24 of the first mechanism if necessary).
- the inclination of the link 1 72 decreases and the second end 22 of the ramp 2 is lowered.
- the ramp 2 is reengaged in its guide rails 1 5 and brought back (manually or by the engine 1 7) inside the frame 10.
- this or these lever mechanisms activated at the end of the extraction stroke by said ramp 2, a movement of extraction of the ramp, initially essentially horizontal, is transformed into a movement having a vertical component for raising the upper end of said ramp 2.
- the different lever mechanisms can be designed to be activated simultaneously, that is to say on a substantially identical end-of-travel portion.
- the main lever mechanism can be activated before the secondary lever mechanism or vice versa.
- the secondary lever mechanism initiates the raising of the ramp.
- the main lever mechanism (foot 24) is activated (FIGS. 4e, 5e) after the secondary lever mechanism (connecting rod 1 72) (FIGS. 4c, 5c).
- the ramp 2 then has a first neutral extraction phase (FIGS. 4a, 4b, 5a, 5b), an elevation initiation phase (FIGS. 4c, 4d, 5c, 5d) in which only the secondary lever mechanism is active, and a fully elevated phase ( Figures 4e, 4f, 5e, 5f) in which the main lever mechanism is also active.
- a single drive movement then makes it possible both to extract the ramp 2 substantially horizontally and to raise the upper end 22 of the ramp 2.
- this advantageously allows the use of a single engine 1 7 for these two phases of extraction and storage.
- this advantageously allows the exercise of a single continuous force of traction or thrust without the operator having to change grip.
- the upper end 22 of the ramp 2 is thus raised relative to its normal extraction height (substantially the height of the guide rails 1 5 in this case) up to, if necessary, exceed the upper limit of the frame 10 and level with the floor or upper floor 4, or at least approach it to minimize the jump.
- the ramp 2 pushes the flap 1 4 which pivots about its axis and comes substantially in the continuity of the running surface of the ramp.
- the flap 14 thus makes it possible to fill the residual space remaining between the ramp 2 and the upper floor 4.
