Definitions

  • the invention relates to a flat lift a lifting plate which is supported on a pivotable on the base frame
  • Lift arm is articulated, the lift arm via a drive engaging the lifting arm around a pivot axis is pivotable on the base frame and with the drive over a handlebar with a pivot point above the pivot axis of the lifting arm on the base frame is connected to the lifting arm, which with the lifting arm in the retracted position is higher than the point of attack of the drive on the handlebar.
  • Lifts which should be designed so that when retracted Position on the platform or lifting plate is not above the Lifting plate protruding parts remain, for example from WO 89/11437 or WO 89/11438.
  • These known devices are around movable devices with which a lifting of a Motor vehicle by a predetermined stroke, for example Tire change is made possible.
  • the well-known constructions need a relatively large drive when out of stretch loads have already been lifted out of the drive should. Usually such a device Load picked up and lifted only after a predetermined stroke.
  • the invention now aims to provide a low-profile lift to create the type mentioned, in which with essential lower overall height and smaller drive units already heavy loads away from the fully retracted position can be safely lifted.
  • the flat design is said to be in particular enable such a lifting platform also subsequently in floor constructions or ceiling constructions a workshop can be installed without this reinforcement of the floor or ceiling is required, and without the need for openings in the floor or ceiling in order to create the space required for the drive units.
  • the lifting platform essentially in that the handlebar as a two-armed pivotable lever is designed in the manner of a toggle lever, the one between the free ends of the two-armed lever Swivel axis in at least one other link Height direction is pivotally supported on the base frame.
  • a kind of toggle lever is formed, where when the drive is extended first under the toggle action of this handlebar a first partial pivoting the lifting arm is made.
  • the translation of the The toggle lever allows a much smaller drive and therefore a flatter construction when the drive be accommodated in the base frame and under the lifting plate should.
  • the training is now such that the Handlebar is designed as a two-armed pivotable lever, whose pivot axis in at least one other link Height direction is pivotally supported on the base frame.
  • the Handlebar is designed as a two-armed pivotable lever, whose pivot axis in at least one other link Height direction is pivotally supported on the base frame.
  • the toggle action and operational safety can be but significantly improved by a pivotable linkage, whereby in that at least one other handlebar in the height direction is pivotally supported on the base frame, via a longer swing path of the lifting arm the advantageous translation of the toggle lever gear comes into effect.
  • FIG. 1 shows a side view of the lift removed side wall in the retracted position of the lifting plate and in the end position;
  • Fig. 2 is an analog representation with the lifting plate half raised and
  • FIG. 3 a top view the representation of Fig. 1 at a location below the lifting plate.
  • Fig. 1 is designed as a two-armed lever Handlebars visible, which is effective as a toggle lever.
  • the Handlebar 1 is on two further handlebars 2 on the base frame hinged hinged, the swivel axis with 3 is designated.
  • a hydraulic cylinder piston unit 5 struck, the other free end engages on a lifting arm 7 so as to be pivotable about a pivot axis 6.
  • the lifting arm 7 is attached to the base frame so that it can pivot about the axis 8.
  • the second free end of the two-armed lever 1 acts on the lifting arm 7 via a articulation point 9.
  • a handlebar 10 can be seen, which together with the lifting arm 7 a parallel guidance of the lifting plate 11 results, the parallelogram 7 and 10 via the swivel axes 12 and 13 are connected to the lifting plate 11. Guide the handlebars 7 and 10 thus the lifting plate 11 parallel to the plane of the base frame.
  • FIG. 1 takes place when the cylinder-piston unit 5 is loaded first a shift of the two-armed, effective as a toggle lever Lever 1.
  • This shift will be simultaneous the handlebars 2 pivoted about their pivot axis 3, so that the Toggle lever effective first two-armed lever 1 in total in one higher position is pivoted, thereby introducing force is further improved in the lifting arm 7.
  • the Most favorable force introduction is dashed in Fig. 1 achieved end position shown, in which the cylinder-piston unit 5 oriented in a substantially vertical direction is.
  • Fig. 3. 3 is can be seen that the articulation axis 3 of the link 2 with the articulation axis of the parallelogram link 10 essentially coincides, whereby a particularly compact design is achieved becomes.
