Definitions

  • the invention relates to a jack with a standing on the ground Stand body and one on this stand body about a horizontal pivot axis movably attached support arm according to the preamble of claim 1.
  • the movement of the support arm is known to be at the free end of the support arm opposite end arranged toothed segment with a longitudinal toothing of the spool cooperates, transferred. adversely According to the known prior art, the longitudinal toothing of the spool formed by introducing waves into the spool. The gear segment of the support arm then engages in the spool shafts.
  • This training has the disadvantage that the tooth forces to press the control slide leads against the wall of the pedestal. As a result, high wear occurs both on the toothing as well as on the control spool and the pedestal.
  • the invention is based on the problem of wear of the teeth on the support arm and reduce on the control spool.
  • the control slide according to the exemplary embodiment is a single-joint jack with a pivoted foot.
  • Such jacks have, as shown in FIG. 1, a standing body consisting of a standing column 1, at the uprising end of a foot 2 is articulated, on.
  • the foot 2 stands with its footprint 3 on the ground 4.
  • a support arm 5 is pivotally articulated on the column 1.
  • At the free end 6 of the support arm 5 is adapted to the counter receptacle of the vehicle to be lifted, attached support element, not shown.
  • This support element can also be designed such that it can be tilted or in some other form and encompasses, for example the threshold seam of the vehicle to be lifted.
  • Stand column 1 and support arm 5 are connected to each other via a movement spindle 7.
  • a movement nut, not shown at the upper end 8 of the pedestal 1 causes that when turning the movement spindle 7, which is usually designed with a hand crank 9, the support arm 5 is pivoted relative to the pedestal 1, thereby raising or lowering the free end 6 of the support arm 5 and thus the vehicle relative to the ground 4 is effected.
  • Both foot 2 and column 1 and support arm 5 are made of sheet metal and have a U-shaped cross section. They therefore each have a middle leg and two side legs. At the free end 6 opposite end of the Support arm 5 are the side legs 11 of the support arm 5 over approximately 180 ° with a toothing - here a circular toothing - trained. The middle leg 12 of the support arm 5 does not reach the toothing. Therefore, two tooth segments 13 are created. In the engagement area of the teeth of the support arm 5, the middle leg 14 is the Column 1 convexly bulged outwards. By this bulge 15 is a Freedom of movement of the toothed segments 13 with respect to the center leg 14 of the pedestal 1 scored.
  • the control slide 10 is in two parts, consisting of a guide part 16 and one Push part 17, formed.
  • the guide part 16 is made of sheet metal manufactured and has a W-shaped cross section.
  • As counter teeth are in Guide part 16 holes 18 introduced into which the teeth of the toothed segments 13 engage.
  • the thrust part 17 is formed in the exemplary embodiment by a rod which has a crank 20 at its lower end 19.
  • the control spool 10 also presses its lower end 19 on the middle leg here forming the contact surface 3 of the foot 2.
  • the end 19 of the spool 10 is at another point on the footprint 3 of the foot 2. This allows the control behavior of the Foot 2 to be adapted to the conditions of the vehicle to be lifted.
  • the two-part design of the control slide 10 not only brings about a reduction in weight. It also has the advantage of simpler manufacture and one Adaptation of the jack to the vehicle to be lifted while keeping many same components.
  • different materials can be used for the guide part 16 and thrust part 17 can be combined.
  • the guide part 16 can, for example also a plastic part that is injection molded or cast instead of sheet metal can be used. But it can also be made from a die-cast part, for example Metal are used.
  • the connection between guide part 16 and thrust part 17 can be by welding, clipping or Caulking.
  • the guide part 16 has a W-shaped one Cross section formed.
  • This formation, through which two longitudinal grooves 21 arise, has the advantage that the toothed segments 13 arranged on the support arm 5 pass through the side surfaces of the longitudinal grooves 21 are guided laterally. This will cause a buckling the toothed segments 13 prevented.
