Definitions

  • the invention relates to a jack with at least one main leg and a support arm connected to it in a vertically movable manner, the position of which can be changed by means of an adjusting device and in the region of its outer free end a support plate with a depression and an adjoining support surface, which by means of a horizontally extending axis is pivotally connected to the support arm via at least one eyelet formed in one piece from a support plate part.
  • jacks of the type mentioned at the outset are already known.
  • a disadvantage of these jacks the tabs surrounding the bolt or the axle can be bent open in the event of very strong one-sided loading.
  • Such a one-sided load occurs in particular when, for example, the jack must be set up obliquely with respect to the vehicle on a rising road. If the support plate detaches from the support arm due to the bending of the eyelet, there is a risk that the lifted vehicle will tip back, causing a great risk of injury to the operator.
  • the invention has for its object to design and arrange the support plate movable on the support arm in such a way that no damage to the support plate or the connections between the support plate and the support arm can occur even when the support plate is subjected to one-sided loading.
  • This object is by the features listed in the characterizing part of claim 1 solved.
  • This design provides a secure mounting of the axle, so that even with one-sided loading of the support plate, especially when the jack is tilted, the axle is not levered out of the eyelet, since it can no longer be bent open. This is achieved in particular in that the ends of the eyelets remain in one piece with the parts of the support plate even after punching out, and thus a permanent connection is ensured between the ends of the eyelets and the support plate.
  • eyelets receiving the support plate and axle can also be preassembled as an assembly according to claim 2 and then firmly connect the assembly to the support arm, for which purpose the axle is butt welded to legs of the support arm, for example.
  • the eyelets which are arranged at a distance from one another, come into contact after mounting of the support plate on the support arm against parallel legs of the support arm, so that lateral adjustment of the support plate is prevented.
  • the axle has, as an alternative to receiving the eyelets, groove-shaped depressions which prevent the support plate from being displaced on the axle.
  • the eyelets are arranged on the underside of the support plate, so that a flat contact surface is ensured on the support plate.
  • 10 denotes a jack, which consists of a support leg 12 and a support arm 16 which is connected to it by means of a pivot pin 14 and which can be pivoted vertically.
  • the supporting leg 12 has a storage plate 18 with a roller foot 20 at its lower end. With the parking plate 18, the jack 10 is parked on the floor when attached to the motor vehicle.
  • a stand plate 22 arranged at an angle to the positioning plate 18 is also provided on the roller foot 20.
  • an adjusting device 26 designed as a threaded spindle 27, which is pivotably mounted with the aid of a spindle nut 28.
  • the spindle nut 28 has pins 30 on both sides, by means of which the spindle nut 28 is received in side cheeks 32 of the supporting leg 12.
  • the support arm 16 is articulated via a spindle abutment, not shown, for. B. a roller bearing, one bearing disc is acted upon by the threaded spindle 27 and the other bearing disc has pins 34 which engage in the side walls 54 of the U-shaped support arm 16.
  • the support arm 16 is connected in an articulated manner to the support leg 12 via the hinge pin 14 and, according to the adjusting device 26, carries out pivoting movements relative to the support leg 12.
  • the support plate 40 has a recess 42 for receiving a sill seam of a vehicle floor, not shown in the drawing.
  • a support surface 44 adjoins the recess 42 of the support plate 40, which can lie against a vehicle floor in such a way that the sill seam of the motor vehicle remains free from the support plate 40.
  • the support surface is dimensioned as large as possible.
  • two eyelets 50 arranged at a distance from one another are punched into the support surface 44 of the support plate 40, the ends of the eyelets 50 remaining connected in one piece to parts of the support plate.
  • the eyelets 50 provided on the underside of the support surface 44 serve to receive an axle or a bolt 52.
  • the support plate 40 and the axle 52 can be designed as a preassembled subassembly, so that these then easily connect to the front end of the support arm 16 leaves.
  • a firm connection between the support plate 40 and the front end of the support arm 16 is obtained in that the axis 52 is butt welded to side walls 54 of the support arm 16.
  • the distance between the inner surfaces of the eyelets 50 is slightly larger than the distance between the outer surfaces of the side cheeks 54, so that when the support plate 40 is connected to the front end of the support arm 16, the inner surfaces of the eyelets 50 against the outer surfaces of the side cheeks 54 come to rest and thus prevent displacement of the support plate 40 on the bolt or the axis 52.
  • Securing in the axial direction of the support plate 40 is also possible in that groove-shaped depressions are provided in the bolt, into which the eyelets 50 can snap. For this purpose, after inserting the axis 52 into the eyelets 50, the eyelets are pressed together until they engage in the grooves provided.
