Definitions

  • This invention relates to a motor vehicle lifting device, particularly for vehicle bodies.
  • Motor vehicle lifting devices are known and enable mechanics to work under the vehicle lifted in this manner. Devices of this kind are used in vehicle repair shops, body shop, service stations, tyre fitting centres etc.
  • lifting devices consisting essentially of a lift comprising four columns along which a frame on which the vehicle can be raised is vertically mobile.
  • the templates of a conventional shaping bed can be applied to this frame. All is well known, the purposes of these templates is to check whether there are deformations in the body of a vehicle which has been involved in an accident, and to remove them if present.
  • EP-A1-0 240 947 describes a motor vehicle lift with two runways on which the wheels of a vehicle rest. When the lift is raised the particular shape of the runways and their folding allows the vehicle to rest with its body on the runways.
  • DE-A1-3 807 796 describes a frame provided with two arms on which the wheels of a vehicle rest. After having stopped these wheels, the two arms can be raised hinged on one side thus laterally inclining the vehicle.
  • the invention relates to a motor vehicle lifting device, particularly for vehicle bodies, characterised by comprising:
  • the lifting device comprises a base 1 to be rested on and/or secured to the floor 2.
  • this base is shown simply resting on the floor, but the invention provides for it to be also secured to the floor, for example by foundation bolts, or alternatively it can be housed in a suitable recess in the floor, so that as will be apparent hereinafter the lift allows the vehicle to be positioned on the lifting frame without requiring runways and upward ramps, which are difficult to use if the vehicle is without its engine.
  • the base 1 preferably consists of a C-shaped metal section with its opening facing upwards and its longitudinal edges bent horizontally inwards. Two unequal uprights 3 and 4 are retained on the base 1 at their lower end.
  • the upright 3, of length substantially double the length of the upright 4 is provided at its lower end with a pair of rollers 5 by which said end can slide along the base 1 between its longitudinal edges.
  • a conventional safety device consisting of a pawl 6 removably engageable in a series of teeth 7 provided on the bottom of the base 1.
  • the upright 4 which, as stated, has a length substantially equal to one half the length of the upright 3, is hinged at its lower end to the base 1 by a fixed horizontal pin 8, and is also pivoted at its upper end on a horizontal pin 9 fixed to the upright 3 at a central position thereof.
  • an actuator consisting for example of a hydraulic double-acting cylinder-piston unit 10, the purpose of which is to vary the angle between the two uprights 3 and 4 to thus raise and lower a support frame 11 for the vehicle.
  • the frame 11 is in fact formed from an inner plate 12 directly hinged to the upper end of the upright 3, and a framework 13 for securing the vehicle.
  • the framework 13 is connected to the plate 12 along their adjacent longitudinal sides, the connection, in the form of a disengageable hinged connection, being made by a simple manually operated catch or an automatic mechanically operated pin. In all cases the two pairs of longitudinal sides can also be both engaged simultaneously, to keep the framework 13 locked to the plate 12.
  • actuators 14 in the form of hydraulic cylinder-piston units with their axes parallel, their purpose being to incline the frame 11 to the horizontal plane in the longitudinal direction, as will be apparent hereinafter.
  • a hydraulic cylinder-piston unit 15 of vertical axis the purpose of which is to laterally incline the framework 13 relative to the plate 12 about one of the two hinged pairs of sides when the connection on the opposite side has been released.
  • two runways 16 to enable the vehicle to climb on.
  • They consist of two plates which can either be permanently connected to the framework 13, in which case they will be hinged to it so that they can be folded towards the base when the body repairers are working on the vehicle, ie when they are not in use, or be removably connected to said framework, in which case they can be removed when not in use.
  • Connectors are also provided in the framework 13 for the templates which overall form the so-called "dummy frame" for the various vehicle types, ie those structures having fixed reference and locator points for the various vehicle types, to allow verification of the correct body shape or to remove any accident-derived deformation.
  • the templates and the method for connecting them to the framework 13 are of conventional type they have been omitted from the drawings for simplicity of representation.
  • the lifting device operates as follows: when the lift is lowered (see Figure 2) the frame 11 practically rests on the base 1 with the runways 16 connected to the framework 13 and slightly inclined forwards analogously to this latter, to allow the use of short inclined ramps 17 preferably of removable type, to enable the vehicle to climb on.
  • the runways 16 can be folded downwards or removed, giving the body repairer more easy access to the lower parts of the vehicle.
  • the cylinder-piston unit 10 is fed to raise the lift.
  • the outlet of the cylinder-piston unit 10 can be directly connected to the inlet of the cylinder-piston units 14, so that the oil which is discharged by the piston of the cylinder-piston unit 10 during its elongation causes the cylinder-piston units 14 to extend.
  • Suitable limit switches prevent the frame 11 inclining beyond a predetermined maximum safety value.
  • suitable safety devices prevent simultaneous disengagement of both the hinges and also prevent operation of the disengagement system when the frame 11 is laterally inclined.
  • the lifting device according to the invention is suitable for use in workshops and service stations in general, but is particularly advantageous for use in vehicle body shops because of the facility for inclining the vehicle in any direction when it has been lifted and its body fixed to the templates fitted to the lifting frame 11, and consequently because those body parts which require repair can now be presented properly to the repairer.
  • the device of the invention occupies a small overall size and enables repairers to move comfortably about the raised vehicle under conditions of total freedom and absence of obstacles.
  • the device of the invention combines the advantages of reliable and safe operation with extreme versatility and adaptability to almost any type of motor vehicle.
  • the lifting device which has the same basic characteristics as those described for the device of Figures 1 to 4, incorporates however some modifications which make it preferable for certain uses.
  • this device has the central control unit, the electric motor, the solenoid valves and the relative electrical controls completely housed within the upright 4. In this manner the only connection between the device and the outside is an electric cable for powering the pump operating motor.
  • the base 1 is not designed to be rested on or secured to the floor 2, but instead is provided with wheels 18 to enable the lifting device to be transferred, and which as stated requires only a single electrical socket for its operation.
  • the cylinder-piston unit 10 is of the type provided with incorporated mechanical safety members, so dispensing with the need for the safety members 6 and 7 provided at the lower end of the upright 3 and in the base 1.
  • a cylinder-piston unit provides with this type of safety system is described for example in the document EP-A2-0224914.
  • the framework 13 comprises a pair of C-shaped longitudinal members with their opening facing outwards and arranged to support clamps 19 in a longitudinally adjustable position, for securing the vehicle body.
