Definitions

  • the invention relates to a jack with a support leg and a support arm, the jacks controlled via control arms to form a parallelogram are connected.
  • the jack has a support plate that leads to the outside the sill is formed with a body stop, which is when attaching of the jack against an upwardly bent stop leg lets the outside of the sill put on.
  • a jack is out known from DE 85 13 830 U1.
  • the starting position, and thus the height of the jack is even deeper in the event of a flat tire when the vehicle is on the rim.
  • a jack according to the prior art is different in these Attachment positions do not ensure that the body stop of the support plate can be clearly placed against the outside of the sill and at the same time the support plate freely and without too much space under the sill rebate can be pushed through, whereby a clear positioning of the jack would be guaranteed under the vehicle floor.
  • the invention has for its object to design the jack so that at different attachment heights of the jack under the vehicle one about the same position of the support plate and the body stop with respect to the Sill and the sill rebate is guaranteed.
  • the advantages achieved by the invention are in particular that in vehicles with deep-drawn sills a simple and clear application of the Jack under the vehicle floor is made possible. It is different at deeply lowered vehicle in approximately a similar attachment position the jack and the support plate. In particular, it can be ensured be that the jack is not slanted under the vehicle is, which would risk that the jack outside the friction cone would be set and could slip under the raised vehicle.
  • the jack shown in the embodiment consists of a mainstay 1 and a support arm 2, which are rotatably connected to one another via a joint 3 are.
  • the supporting leg 1 stands at the end via a foot 4 on the base 5 on.
  • the foot 4 is firmly connected to the supporting leg 1.
  • It is a so-called tilting foot that is used when the jack is raised tilts forward with the supporting leg 1 via a tipping edge 6.
  • About more joints 7, 8 are rotatably mounted on the supporting leg 1 and on the support arm 2 control arms 9, 10, which in turn are connected to one another via a further joint 11.
  • the Control arms 9, 10 are attached to the support leg 1 and the support arm 2 in such a way that Stand leg 1 and support arm 2 over the joints 7, 8.
  • this movement spindle 12 on the joint 11 via a rotary bearing 13 and on the joint 3 via a spindle nut 14 is articulated.
  • the movement spindle 12 can be used to attach the Jack can be adjusted via a handwheel 15.
  • the one described above The jack construction thus has a movement parallelogram.
  • the leg end of the control arm 10 ends in a control plate 16. This is a common training for both jacks with a tilt foot also with a swivel foot, which ensures that the jack is in the positioning position receives a position perpendicular to the substrate 5.
  • this support plate 19 has a support section 20 which is used for lifting the Vehicle inside the vehicle next to the sill rebate 21 under the floor 22 of the Vehicle lays.
  • the support plate 19 is towards the outside 23 of the sill 24 is formed with a body stop 25 that extends far.
  • an upwardly bent stop leg 26 is arranged.
  • a plastic profile 27 is pushed over the stop leg 26, which serves not to paint the sill 24 when the jack is attached to damage
  • the jack has a spring 28 as a control element for the position of the support plate 19.
  • the spring extends approximately in an extension of the direction between the joints 11 and 7 beyond the support arm 2 to below the body stop 25 of the support plate 19.
  • the spring 28 wraps around the joint with at least one turn 7 forming bolt and is supported with its other end 29 against the ground 30 of the U-shaped control arm 9. This measure extends the spring 28 always approximately in the direction of the connection between the joint 11 and Joint 7 beyond the control arm 9.
  • the spring 28 shown in the embodiment is made of steel wire.
  • the length of the protruding leg of the spring 28 corresponds approximately to the distance between the joints 7 and 18. This results in the connection of the joints 7, 18 and the contact point of the free spring leg under the body stop 25 an isosceles triangle. Since the protruding end 17 of the Support arm 2 and the protruding end of the spring 28 together with the control arm 9 approximately the same angular movements, but in different directions of rotation, perform, the support plate 19 is approximately in a constant angular position held.
  • the support arm 2 is also formed as a sheet metal profile, which is approximately U-shaped Has cross section.
  • the spring 28 penetrates a slot 31 in the bottom 32 of the support arm 2. This slot 31 is in the direction of the projecting end 17 of Support arm 2 limited.
  • This measure of the invention serves to avoid disturbing the spring when actually lifting the vehicle. In particular, the spring 28 could interfere with the lowering of the vehicle jam against the support plate 19.
  • FIG. 3 shows a jack in collapsed condition.
  • the support plate 19 is spread apart from the support arm 2, the support plate 19 at the end of the supporting section with a sheet metal tab 33 bent downwards educated.
  • This sheet metal tab 33 bumps when the jack is moved together to the bottom 30 of the control arm 9, which at this point has a bulge 34 is trained.
  • This placement of the sheet metal tab 33 on the bottom 30 of the control arm 9 causes the support section 20 to be raised relative to the support arm 2 and a complete or almost complete application of the Body stop 25 on the support arm 2.
  • the body stop 25 can even how shown in Fig. 3 until immersed in the profile of the support arm 2. Because of this Swinging the support plate 19, the spring 28 is tensioned, which is advantageous has the effect that the support plate 19 compared to the retracted Jack does not rattle.
