Definitions

  • the present invention relates to handling devices, in particular load lifting systems, and relates to a lifting platform for vehicles, more particularly for automobiles, with wheeled or under body socket.
  • vehicle lifts for existing vehicles generally belong to one of the following two groups: under-wheel drive or under-body or chassis drive.
  • the garage owner must, on the one hand, have two different lifting lifts, one from each of the two aforementioned groups, and, on the other hand, move the vehicle from one bridge to the other depending on the type of operations. planned repairs or maintenance.
  • lift lifts which integrate two lifting devices, each of which is surmounted by a specific support support, each carrying out one of the two aforementioned lifting modes.
  • lifts with mixed grips constituted by a first lifting device / support support under wheels assembly, in which is mounted a second lifting device / support support under body, which can emerge therefrom telescopic.
  • the object of the present invention is in particular to overcome all of the aforementioned drawbacks, by proposing a lift having only one lifting device but allowing the two lifting modes.
  • a vehicle lift essentially comprising a lifting device and a support support, mounted on said lifting device and intended to support the vehicle to be lifted, characterized in that the support support is composed of two separate structural support sets, one of which allows the vehicle to be raised with support at the body or chassis and the other which allows the vehicle to be raised with support at the wheels, both structural support assemblies which can be secured together and / or with the lifting device in a removable manner.
  • the vehicle lift essentially comprises a lifting device 1 and a support support 2, mounted on said lifting device 1 and intended to support the vehicle 3.
  • the support support is composed of two separate structural support assemblies 4 and 5, one of which 4 allows the lifting of the vehicle 3 with support at the level of the body 6 or the chassis and of which the another 5 allows the lifting of the vehicle 3 with support at the level of the wheels 7, the two structural support assemblies 4 and 5 being able to be joined together and / or with the lifting device 1 in a removable manner.
  • the support support 2 is advantageously constituted, on the one hand, by two elongated plates 8 or two bars, fixed on the ends upper parts of the lifting device 1 and extending at least partially under the lower lateral edges of the body 6 or of the chassis, located between the front and rear wheels 7, of a vehicle 3 disposed on said lift and, on the other part, by two or four plate portions 9 located at the locations of the front and rear wheels 7 of the vehicle 3 disposed on said lift and which can be assembled, in a removable manner, with said elongated plates 8 or bars or with the upper ends of the device of lifting by means of sliding securing segments 10.
  • plate in the present invention flat and rigid supports, namely, both solid supports or trays, as openwork supports or in the form of gratings.
  • first structural support assembly 4 may be in the form of bars or rails, which can be positioned by adjustment directly under the side rails of the underbody of the vehicle 3 to be lifted, or even in the form of a single plate extending substantially over the entire surface of the underbody of vehicles 3, it is preferred that said first structural assembly 4 consists of two elongated plates 8 having a large bearing surface (adaptation to vehicles of different widths without adjustment), while providing a central opening allowing access to the underbody when the vehicle 3 is raised (Figure 7).
  • the second structural support assembly 5 can consist of two plate portions, one for each pair of wheels 7 (front and rear), or four plate portions 9, one for each wheel 7, the latter arrangement allowing to provide an opening to access the parts of the vehicle 3 located between said wheels ( Figure 7).
  • the four plate portions present are advantageously rigidly connected together, two by two, on the one hand, longitudinally by means of longitudinal members 11 extending under the elongated plates 8 or bars forming the first structural assembly 4 of the support support 2 and, on the other hand, transversely, two by two, by one or more crosspieces 12, so as to constitute a second structural assembly 5, of the support support 2, in one piece.
  • the sliding securing segments 10, preferably at least one for each plate portion 9, are guided in slides 13 fixed under the plate portions 9 intended to support the wheels 7 or on the side members 11 connecting said plate portions 9 together, in pairs, and can be moved, alternatively, from a retracted position, corresponding to a non-use of the second structural support assembly 5, towards a deployed position in which they partially engage in slides or over supports 14 mounted under the elongated plates 8 or on the bars of the first structural support assembly 4.
  • the displacement of the sliding fastening segments 10 can only be carried out in the low or fully folded position of said lift, the actuating means or means 15 provided for this purpose being mechanically separated and separated from the drive members 16 of said segments joining 10 during deployment of the lifting device 1 and the lifting of the support support 2, that is to say of the first structural support assembly 4 alone or of the first and second structural support assemblies 4 and 5 simultaneously ( Figures 1 and 5 of the accompanying drawings).
  • the choice of lifting mode is made when the lift is in the low position, the assembly between first and second structural support assemblies 4 and 5 being locked and blocked, when it is effective, due to the action of the weight of said second structural assembly 5 and, if necessary, of the vehicle 3 raised on the slide links 13 / securing segments 10 / supports 14.
  • the actuation means consist of at least one jack 15 mounted on the lower part or on the base of the lifting device 1 and of which the rod 15 ′ carries a connector end piece 17 and, as shown in FIGS. 1 and 5 of the appended drawings, the drive members 16 comprise at least one attachment member 18 which can come into engagement, each with at least one end piece connector 17 for the transmission of the translational movement of the rod 15 ′ of the jack 15 corresponding to the securing segment (s) 10 connected to said drive members 16, the engagement and disengagement of each member hooking 18 with the corresponding connector end piece 17 being effected by simple vertical displacement, generated during raising or lowering of the lift.
  • the securing segments 10, preferably in the form of portions of bars of rectangular section provided with a lower beveled front edge, can each be actuated by own actuation means by means of as many organs suitable drive or optionally in pairs, in particular in opposite pairs, each of which can be connected to a jack for the purpose of moving said fastening segments, from the plate portions considered towards the elongated plates or vice versa.
  • the securing segments 10 are housed in slides 13 fixed on the side members 11 connecting the plate portions 9 between they, two by two, and can extend, in the assembly position of the two structural assemblies 4 and 5 of the support support 3, over the supports 14 provided on the underside of the elongated plates 8 of the first structural assembly d 'support 4, said securing segments 10 being interconnected longitudinally, two by two, by rods 19.
  • a single drive member 16 transversely connecting two of the segments of attachment 10 and provided with a fastening member 18 consisting of a vertical plate provided with a notch-shaped cutout 18 'and, on the other part, a single actuating means, for the displacement of said securing segments 10, in the form of a jack 15 mounted on the lower part or on the base of the lifting device 1, can only be actuated in position bottom of the lift and comprising a connector end piece 17 with two stops 17 'on its rod 15' so that the vertical plate 18 forming a hooking member can engage between the two stops 17 'and the middle part 17'' of the nozzle 17 insert into the notch 18 'of said vertical plate 18 when said lift reaches the low position.
  • the lifting device 1 may consist of a set of two lateral columns 20 whose sliding support bearings 20 'are integral with the elongated plates 8 or bars of the first structural support unit 4.
  • the lifting device 1 is constituted by an articulated structure deformable in double scissors or in double pantographs, which can each be deployed under the action of a corresponding power jack 21, actuated together in a complementary manner, so as to obtain a symmetrical and balanced deployment of the two scissors or pantographs.
  • the second structural support assembly 5 is, in the event of non-attachment to the first structural support assembly 4, and during deployment of said lift, raised up to and maintained in an intermediate position by means of support points 22, 23 mounted on the lower parts of the arms 1 'of the scissors or pantographs forming the lifting device 1.
  • This arrangement makes it possible to proceed, in the case of a configuration of the support support 2 for a lifting with grip or support under the body or shell of the vehicle 3, to initiate the lifting with support of the wheels 7 on the plate portions 9 (FIG. 5A), then, when the elongated plates 8 or the rubber wedges placed on the latter come into contact with the bottom of the body of the vehicle 3, gradually take off said vehicle from its support on the plate portions 9 and bring it to the maximum lifting position, resting entirely on the first structural support assembly 4.
  • the lifting of the vehicle 3 with grip or support under the body or the chassis of the latter is done gradually during the lifting movement, due to the differential speed of climb between the first 4 and the second 5 together structural support and not at the start of lifting and suddenly or suddenly.
  • the plate portions 9 constitute, in their intermediate lifting position, tables or worktops at mid-height allowing the deposition of tools, devices, dismantled parts of the vehicle, spare parts or analogues (Fig. 1 and 5C).
  • the support points 22, 23 may advantageously consist of a on the one hand, in two concave open bearings 22 receiving a transverse axis or two lugs 24, integral with the side members 11 or plate portions 9 for a removable pivot connection by lifting, and, on the other hand, in two rollers 23 on which are supported corresponding raceways 25 integral with the side members 11 connecting the plate portions 9 to each other, said bearings 22 and rollers 23 being installed at similar locations on opposite arms 1 ′ of the same chisel 1 or pantograph.
  • This link removable by lifting, between the second structural support assembly 5 and the lifting device 1 allows said structural assembly 5 to be lifted and supported by the latter, without however this articulated attachment interfering with the folding or the spacing of the arms 1 'of scissors or pantographs.
  • the first and second structural support assemblies 4 and 5 rest on ground supports 26 or on the base of the lifting device 1 and the slides 13 guiding the securing segments 10 are aligned with the corresponding slides or supports 14 of the first structural assembly 4 so that said securing segments 10 can be engaged or disengaged relative to said slides or said supports 14 by the intermediate the drive members 16 controlled by the actuating means 15, even in the presence of a vehicle 3 on said lift, said actuating means 15 being blocked when the latter leaves said low position (FIG. 1 and 5A).
  • the lift can also comprise, on the one hand, one or more position detectors or limit switches 11 not authorizing the operation of the actuating means 15 with a view to moving the securing segments 10 only in the low or folded position of the lift, and, on the other hand, one or more position detectors or limit switches preventing any movement of the lifting device 1 when the securing segments 10 are not disposed in a position of engagement or total clearance relative to the slides or to the corresponding supports 14 forming part of the first structural support assembly 4.
