Definitions

  • the invention relates to a jack according to the preamble of claim 1.
  • Carrying parts of jacks are pivotally connected to each other by joints.
  • the supporting parts of the jack are formed as a cross-sectionally U-shaped profiles with side profile legs.
  • Other supporting parts, such as the jack head or the Wagenheberfuß are formed with laterally upstanding metal tabs.
  • the connection of these supporting parts is done such that the profile legs or the laterally upstanding tabs overlap in the joints and are provided with holes, they are then connected by means arranged in the holes axes.
  • DE-OS 2 231 526 shows such joints, which are used as axles bolts.
  • the axes are formed by necklaces.
  • a generic jack with the features of the preamble of claim 1 is known from EP 0 885 834 A2.
  • protruding walls are provided vertically from the bottom plate of the jack base in the direction of his leg, which are arranged opposite to each other.
  • the one wall serves to limit the angle of rotation of the supporting leg relative to the jack foot.
  • the other wall serves, together with the vertical side walls of the jack foot to form a space in which the Leg of the jack intervenes so as to control the movement of the leg.
  • the invention has the object of providing a jack according to the preamble of claim 1 such that the risk of kinking of the profile legs is reduced.
  • Jacks have regardless of their design hingedly interconnected support members that connect the jack foot and the support member height-adjustable with each other.
  • the hinged support members must be able to support the vehicle weight. Therefore, it is necessary for these joints to function safely and consistently.
  • the articulated jack shown in Fig. 1 represents only one type. However, the invention is also suitable for all other types of jacks, which have the prerequisite according to the preamble of claim 1.
  • Articulated vehicle lifter according to FIG. 1 have, as load-bearing parts, jacking foot 1, pillar 2, support arm 3 and support plate 4. All of these supporting parts are articulated to each other via joints 5, 6, 7.
  • a threaded spindle 10 is connected to the leg 2 and the support arm 3, which allows a threaded nut about a pivoting of the support arm 3 relative to the leg 2, which leads to lifting of the support plate 4 relative to the Wagenheberfuß 1.
  • the threaded spindle 10 is driven.
  • the jack foot 1 has as a basic component a bottom 12: with laterally upstanding metal tabs 13.
  • the leg 2 is designed as a U-shaped profile formed, which also has a bottom 14 and side profile legs 15. The same applies to the support arm 3 with its bottom 16 and the profile legs 17.
  • the joint according to the invention is suitable for connecting the support arm 3 with the pillar 2 or the supporting leg 2 with the Wagenheberfuß first
  • connection of the jack base 1 is shown enlarged to the leg 2.
  • 2 to 5 is used to form the joint 5 on both sides outside riveted bolt 18, the holes in the upstanding metal tab 13 of the jack base 1 and in the profile legs 15 of the supporting leg 2 penetrates.
  • FIGS. 2 and 3 are punched on both sides beads 19 from the bottom 12 of the jack foot 1 directed inward. These beads are arranged within the profile legs 15 of the supporting leg 2 close to them. Between sheet metal tabs 13 of the jack base 1, profile leg 15 of the supporting leg 2 and beads 19 is only one required for the pivoting movement game available. As a result, good guidance of the ends 20 of the profile legs 15 is achieved.
  • the beads 19 extend below the bolt 18. Thus, the bolt 18, if necessary, be supported on the beads 19.
  • FIGS. 4 and 5 corresponds approximately to the embodiment according to FIGS. 2 and 3.
  • the beads 21 formed out of the bottom 12 of the jack base 1 are separated from the base 12 on only one side. On the other side, they are firmly connected to it.
  • the joint 5 is formed in that inwardly projecting necklaces 22 from the upstanding metal tabs 13 of the jack base 1 engage in bores 23 of the profile legs 15 of the supporting leg 2.
  • the positional fixing of the ends 20 of the profile legs 15 is formed by inwardly projecting tabs 24. These tabs 24 are, as well as the beads 19, 21, punched out of the bottom 12 of the jack foot 1 and then bent up.
