Definitions

  • the invention relates to a jack according to the preamble of claim 1.
  • DE 36 03 311 A1 shows such a jack in which the base plate is pivoted relative to the pillar by a spring in the fitting position.
  • the disadvantage of this jack is that the base plate is pivoted as far as possible in the longitudinal direction of the pillar in the rest position of the jack. This increases the total length of the jack when fully folded, which means that a longer stowage length in the storage space of the car is required.
  • the invention has for its object to develop a jack according to the preamble of claim 1 such that it has a short stowage length in the fully collapsed state, but the base plate is pivoted when attached to the vehicle in the attachment position so that it rests as fully as possible on the floor.
  • the jack 1 is attached to a bottom plate 4 from a pedestal 2 at its lower end via a joint 3.
  • a support arm 6 is pivoted relative to the pillar, which is made possible by a pivot joint 7.
  • the solid and the dash-dotted representation of the base plate 4 shows the two outermost pivotal positions thereof. In the dash-dotted position, the smallest accumulation length 8 results.
  • a one-piece coil spring with two free ends 10, 11 is shown as the spring element 9.
  • a spring region 12, which is supported against the pillar 2 and the base plate 4, is constructed from the shorter free end 10, the helical part 13 and the first Part of the longer free end 11.
  • the second spring region 14 is formed by the second part of the longer free end 11 and consists of a half loop 15 and a straight extension 16 which ends in a loop 17.
  • a continuous bolt is provided as the joint 3 for connecting the standing column 2 and the base plate 4.
  • Arranged around this bolt is the helical part 13, the helical spring used as the spring element 9.
  • the support arm 6 In the stowed position shown in Fig. 3, the support arm 6 is as close as possible to the column 2. As a result, the pedestal presses on the straight extension 16 of the longer free end 11 of the spring element 9.
  • the spring detection is designed so that the spring force pivoting the base plate 4 is canceled so that the base plate 4 pivots approximately perpendicular to the pedestal 2.
