Definitions

• the present invention relates to an elevator intended to transport people between a lower level and an upper level, particularly intended to be installed in dwellings to facilitate access to the floor of users whose mobility is reduced such as disabled people. elderly for example.
• elevators are well known comprising a cabin or a horizontal platform capable of being translated vertically in a vertical cage from a lower level to an upper level and vice versa by actuating means; this is the case, for example, of French patent FR 2,584,694 describing a hydraulic lift with a cabin.
• the hydraulic elevator comprises a cabin which is connected, by means of support and return pulleys, with a hydraulic cylinder displaceable in the direction of travel of the cabin, said cabin being able to be raised and lowered by the '' supply and discharge of a working liquid.
• the working liquid is supplied to the hydraulic cylinder by means of a pump driven by a motor.
• the piston rod of the hydraulic cylinder fixedly anchored with its upper end, which can come out under the effect of weightlessness to raise the cabin, is connected at its end to a pulley guiding the anchored support means of fixedly at one end and anchored to the cabin at the other end.
• the two arms of a pair are pivotally mounted along an axis which supports a connecting rod, pivotally connected to the ends of the two hydraulic cylinders serving as actuating member, along an axis offset from its mounting axis, which can rotate 90 ° between a generally horizontal position and a position where it will be locked in rotation.
• the connecting rod is advantageously provided with rollers so that these allow a rapid rise of the axis of rotation which links the two arms of a pair together, when the lifting frame is in the base position.
• the existence of the rod itself also allows, thanks to its rotation, by reduction, a rapid rise of the axis of rotation which connects the two arms of a pair between them.
• This type of elevator has the disadvantage of require to implement wholesale and earthworks • the • bottom of the cage to achieve cuvette- below the lower level. to accommodate the hydrostatic drive device, which considerably increases the costs of installing such a lift. Otherwise, the elevator platform cannot be flush with the ground level when the elevator is in the lower position, the arms and the actuating member being arranged below the platform.
• One of the aims of the invention is therefore to remedy this drawback by proposing an elevator of simple and inexpensive design avoiding the production of a bowl at the bottom of the elevator cage.
• an elevator is proposed between a lower level and a level comprising a substantially horizontal cabin or platform capable of being vertically translated into a vertical cage from the lower level to the level upper and vice versa, by actuation means positioned under the remarkable platform in that said actuation means comprise on the one hand at least a pair of arms mounted in scissors, that is to say articulated around 'an axis in their middle part, the free ends of a first arm of a pair being articulated around a fixed axis secured to the cage and respectively to the platform around an axis sliding along the one of the lateral edges of the platform and the free ends of the second arm being articulated around a fixed axis integral with the.
• the actuating member preferably consists of a jack whose body is integral with the cage and whose rod is articulated to a connecting rod articulated to one of the arms of the pair in such a way that the axes of articulation from the connecting rod to the rod of the jack, from the connecting rod to the first arm and from said first arm to the cage is never aligned.
• the cage consists of a framework comprising two rear uprights, two lower side members and rear crosspieces, the free ends of the first arm of a pair being articulated around a fixed axis integral with the rear end of the lower side members and respectively to the platform around an axis sliding along one of the lateral edges of the platform and the free ends of the second arm being articulated around a fixed axis secured to the lateral edge of the platform and respectively to said lower spar about a sliding axis along a longitudinal lumen formed in said spar.
• one of the arms of each pair of arms consists of two segments, a first segment and a second segment extending linearly and in parallel in two 1 Segregated vertical planes, 'said segments being interconnected by a fixed pin secured to the respective free ends of first and second segments and passing through the first pair of arms.
• FIG. 1 is a perspective view of the elevator according to the invention
• - Figure 2 is a vertical sectional view of the elevator according to the invention, the platform being at the upper level
• - Figure 3 is a vertical sectional view of the elevator according to the invention, the flat -form being at the lower level
• - Figure 4 is a schematic representation from above of the elevator according to the invention.
• the elevator according to the invention between a lower level and an upper level of a dwelling comprises a substantially horizontal platform 1 capable of being vertically translated into a vertical cage 2 from the lower level 3 up to the upper level 4 and vice versa by actuating means positioned under said platform 1.
• the cage 2 consists of a frame 5 comprising two front uprights 6a and two rear uprights 6b, two lower side members 7,7 'and front crosspieces 8a and two rear crosspieces 8b.
• the lower beams 7, 7 'of the cage 2 extend above the lower level 3 of the dwelling in order to increase the vertical clearance of the platform 1 as will be detailed below.
• the horizontal platform 1 consists of a generally rectangular plate 9 comprising on its lateral edges and on its rear transverse edge of the guardrails 10 conventionally constituted by uprights and side members forming guard rails. body .
• the elevator also comprises two pairs of arms 11 and 12 mounted in scissors, that is to say a pair of arms articulated around an axis in their middle part, respectively articulated on the lateral edges of the platform. -form 1.
• the free ends of the first arm 11a of a pair 11 are articulated around a fixed axis 13 secured to the rear end of the lower spar 7 of the frame 5 of the cage 2 and respectively to the platform- form 1 around an axis 14 sliding along one of the lateral edges of said platform 1 through a longitudinal slot 15.
• the free ends of the second arm 11b are articulated around a fixed axis 16 secured to the edge lateral of the platform 1 and respectively in the middle part of the lower spar 7 of the frame 5 of the cage 2 around an axis 17 sliding through a longitudinal slot 18 formed in the middle part of said lower spar 7.
• the elevator further comprises a jack 19 which is powered by a hydraulic motor, not shown in the figures, so as to actuate said platform 1.
• This jack 19 extends vertically along the rear upright 6a of the frame 5 of the cage 2, above the lower spar 7, and the rod 20 of said cylinder 19 is articulated to a connecting rod 21 articulated to the first arm 11a of the pair between the articulation of said first arm 11a around the axis fixed 13 secured to the rear end of the lower spar 7 of the frame 5 of the cage 2 and the articulation axis of the first and second arms 11a and 11b mounted in scissors so that the articulation axes of the connecting rod 21 to the rod 20 of the jack 19, of the connecting rod 21 to the first arm and of said first arm 11a to the cage 2 are never aligned.
• the vertical translation of the rod 20 of the jack 19 drives the rotation of the first arm from a first position where said second arm extends above the lower side members 1 -1 ′ of the frame 5 of the cage 2 to a second lower position where said first arm 11a extends below said lower beams 7, 7 'thus providing the translation of the platform 1 from a first position where it extends to the upper floor 4 of the dwelling to a second position where it extends to the lower stage 3 under the lower longitudinal members 7.7 ′ of the framework 5 of the cage 2.
• the lower position of the platform 1 can be confused with the plane of the longitudinal members 7.7 'lower of the frame 5 of the cage 2 without departing from the scope of the invention.
• the second arm 11b for example, consists of two segments, a first segment 11 'bs' extending from the lower spar 7 to the first arm 11b of the pair 11 and a second segment 11 "bs 'extending from the first arm 11a of the pair 11 to the platform 1.
• the free ends of the arms 11b of the first pair 11 of arms are joined to the respective free ends of the arms 12b of the second pair 12 of arms by a bar link 23 so that the rotation of the first arm 11a of the first pair 11 provided by 1 actuation of the jack 19 simultaneously causes the rotation of the first arm 12a ⁇ of the second pair 12.
• the arms 11a and 12a of the pairs 11 and 12 protrude from the rear of the platform 1 to allow the passage of the connecting bar 23 behind the platform when it is moved from the lower level 3 to the upper level 4 and vice versa, said connecting bar 23 extending in the plane of the platform -form 1 when the latter is located at the lower side members 7,7 'of the frame 5.
• the elevator comprises at the upper level 4 a door 24 pivoting around hinges 25 integral with the front uprights of the frame 5 of the cage 2 so that said gate 24 is closed, preventing access to the cage 2, when the platform 1 is located at the lower level 3 in order to prevent any fall from the higher level 4.
• the vertical movement of the platform 1 in the cage 2 is not linear but slightly curved so that, when said platform 1 is located at the lower level 3 or at the upper level 4, said platform 1 is separated from the floor of the lower level 3 or higher by a space.
• the front edge of the platform 1 advantageously comprises a retractable flap 26, prestressed by elastic means and able to slide along rails 27 positioned under said platform 1 in order to fill said space.
