Definitions

  • the invention relates to a lifting platform for motor vehicles with at least one supporting element acting on the underside of the vehicle, which in turn is supported on a base by means of a scissor-type frame, the scissor-type frame having at least two intersecting lower and two intersecting upper scissor levers, each of which has a first at the crossing points Pivot bearings are connected to one another and the lower scissor levers in their upper region are each connected to the lower regions of the upper scissor lever via second pivot bearings.
  • Such scissor lifts are known in numerous embodiments.
  • two support elements are used, each of which has its own scissor-type frame and is arranged next to one another in such a way that it engages under the vehicle on both sides.
  • the aim is to minimize the size of the support elements. It is therefore known in the sense of a particularly narrow construction, the upper and lower scissor levers on their common terminal pivot bearing not to be arranged next to each other but in alignment one above the other.
  • the storage takes place via laterally welded tabs, which protrude in the longitudinal and transverse directions of the scissor lever, so that the upper scissor lever lies flat on the lower one when the lifting platform is folded.
  • the support elements then have a relatively large floor protrusion when the lift is lowered, which can lead to damage when driven over by lowered vehicles or by vehicles with the spoiler pulled down low. That is why such lifts must either be embedded in the floor or equipped with long ramps for ascending and descending.
  • the object of the present invention is to improve the known lifting platforms in such a way that on the one hand they manage with narrow supporting elements, and on the other hand they are characterized by a small floor protrusion when the lifting platform is lowered.
  • the upper or the lower of two pivotally connected scissor levers has a slot running in the longitudinal direction of the scissor lever, the other Scissor lever is open and that this other scissor lever is at least predominantly immersed in this slit in the lowered position of the lifting platform.
  • the lower scissor levers are slotted, the upper scissor levers can be fully immersed in the lower scissor levers when the lifting platform is lowered and do not require any overall height.
  • the lifting platform according to the invention thus combines the advantages of the scissor frames with scissor levers arranged one above the other and with side by side, without having to accept their respective disadvantages. Last but not least, it is also characterized by low manufacturing costs, because there is no need to weld special tabs for the swivel bearings.
  • the scissor levers which should have the slot mentioned, can have any cross-sectional shape.
  • the scissor levers can have any cross-sectional shape.
  • the immersing scissor levers can be upright flat bars.
  • the pivot bearing connecting the lower and the upper scissor lever expediently consists of a bolt which is inserted in the two opposite sides of the slot and crosses the other scissor lever in the intermediate space. This results in a particularly stable bearing with little bending stress on the bolt.
  • a particularly advantageous development of the invention consists in that the scissors levers having the slot have lateral cutouts in their central region for the aforementioned first pivot bearings of the upper scissor lever. This enables the scissors levers that belong together to move together completely without the pivot bearing being in the way. The same measure is also recommended if the upper scissor levers have the usual lateral articulation points for the introduction of the lifting force. These cutouts are expediently arranged only on one side of the slot.
  • reinforcements are provided on the side opposite the cutouts, for example by welded flat iron.
  • the part of the lift shown which is only intended to support one side of the vehicle, consists of a base plate 1, one mounted thereon Scissor frame 2, which can be raised or lowered via a lifting element in the form of two hydraulic cylinders 3 connected in parallel, and a support element in the form of a plate 4 mounted on the top of the scissor frame.
  • Short, pivotable plates 5 are at the front and rear ends of the plate 4 and 6 articulated to facilitate the vehicle to be driven over.
  • the scissor-type frame 2 is initially only described for the scissor levers located at the front in the drawing. Accordingly, two intersecting lower scissor levers 7a and 7b are provided, of which one scissor lever 7b is articulated to a fixed bearing of the base plate 1, while the other scissor lever 7b is also guided horizontally on the base plate in addition to its pivoting movement. Both scissor levers 7a and 7b are connected to one another at their crossing point via a pivot bearing 8, while at the upper ends they each carry further pivot bearings 9 and 10, to which upper scissor levers 11a and 11b are articulated. They run parallel to the lower scissor levers and are connected to one another at their crossing point via a pivot bearing 12. At their upper ends, the upper scissor levers carry the support plate 4, with the same bearing or guiding principle as shown on the base plate 1.
  • the entire scissor-type frame is driven by two cylinder-piston units 3 which are articulated at one end of the base plate 1 and act on the opposite upper scissor-type levers 11a, specifically via articulation points 13.
  • Spreading lever 14 according to the utility model 92 05 900 support the lifting movement from the folded state of the scissor lever until the lifting element has been sufficiently pivoted out of the lower dead position.
  • the lower scissor levers 7a and 7b have corresponding recesses 27a to 27d on the inside and outside sides of the U-profile, each of which is open at the top.
  • the inner scissor levers 7b and 7c have further recesses 28b and 28c on their inner sides for the articulation points 13 of the lifting member.
  • the leg regions of the U-profile lying opposite these recesses are each stiffened by a welded-on flat iron or the like.
  • the present invention provides a scissor system that is not only narrow but also extremely flat and is characterized by high stability. In addition to its use in repair workshops, it is of course also suitable as a lifting device in multiple parking systems.
