Definitions

  • the invention relates to a jack according to the preamble of claim 1.
  • Such a jack has a support plate which can be pivoted transversely to the longitudinal direction of the car. This ensures that the support plate is clearly positioned under the car, regardless of the position of the jack towards the center of the vehicle and regardless of the height of the raised car.
  • DE-C-39 21 826 shows such a jack.
  • the disadvantage of this jack is a one-sided contact of the support plate on the car when it is placed with its pedestal on an uneven floor in the longitudinal direction or when the car makes a forward or backward movement when lifting due to its chassis construction.
  • EP-A-0 469 234 shows a jack in which the support plate can be rotated to a limited extent about a vertical axis relative to the support element of the jack. This makes it possible for the jack to be placed on the floor in the longitudinal direction of the wagon when it is attached to the wagon, which represents a not inconsiderable risk of an accident.
  • the invention has for its object to further develop a jack according to DE-C-39 21 826 such that even misalignments in the longitudinal direction of the car are compensated can be without one-sided stresses that can damage the floor of the car by local pressures, but it is excluded that the jack rotates in the longitudinal direction of the car.
  • the design according to the invention advantageously reduces constraining forces on the jack. However, it is ensured that there is no twisting of the jack under the car can. The jack always stays in alignment.
  • the invention enables a flawless function but nevertheless a cost-effective solution and guarantees a maximum degree of swivel travel.
  • the swivel arm jack described has a support leg 1 and a support arm, which is pivotally connected to it via a joint 2, as a support element 3.
  • the support arm is raised relative to the supporting leg 1 via a threaded spindle 4.
  • the support leg stands on a base 5 on the floor 6.
  • a support plate 8 is arranged so as to be pivotable about a pivot axis 7 extending in the longitudinal direction of the carriage, which is placed under the carriage 9 and lifts it.
  • the support arm ends at its free end in two webs 10, 11 which are connected to a support pin 12 which extends in the direction of the pivot axis 7.
  • the swivel axis in turn runs alongside in the longitudinal direction of the car.
  • the support plate 8 is formed with holding loops 13, 14 which comprise the support pin 12 and thus form two swivel joints 15, 16.
  • the holding loops 13, 14 form an elongated hole, the narrow sides lying horizontally on the support pin 12, but permitting movement of the support plate in the vertical direction.
  • a convex embossing on the underside of the support plate, which is supported on the support pin 12, is provided as a support element 17 between the support plate 8 and the support pin 12 in the middle between the holding loops 13, 14.
  • the embossing has a height 18 which is approximately half the difference between the length and the width of the elongated hole in the holding loops 13, 14 corresponds.
  • jacks such as scissor jacks or double-joint jacks
  • the support element 3 is, for example, the head of the jack.
