Definitions

  • the invention relates to a jack with a body and a support arm movably attached to it according to the preamble of claim 1.
  • Jacks are needed, preferably in the case of a car To be able to raise a breakdown, for example, a defective wheel exchange for a spare wheel. It should be noted that Jacks are safety parts on the one hand, if they fail there is a risk of injury to the operator. On the other hand, jacks are at today's quality used by cars only extremely rarely, so that for most Time of life of a car transported as an additional weight Need to become. This means that the jack is the must have the required safety of a safety part, on the other hand, they should be inexpensive and light.
  • DE 78 01 157 U1 shows a jack according to the preamble of claim 1.
  • the free end of the support arm in the direction of vehicle to be lifted angled In order to ensure on the one hand that the Jack is used in vehicles with low ground clearance can be achieved, with the greatest possible lifting height should and where the jack is as small as possible has, the free end of the support arm in the direction of vehicle to be lifted angled.
  • the one shown here Training the support arm requires a complex and material-intensive Manufacturing, if the support arm as usual as a bent sheet metal part is trained.
  • a similar problem is proposed in DE 75 06 553 U for a mainstay, a correspondingly angled foot by welding to the Stand column to connect. This training requires a complex Manufacturing and, because the weld seam, the highest loads is subjected to an additional weld inspection.
  • the invention has for its object to provide a jack train the preamble of claim 1 such that designed the angle of the support arm with simple means can be. This object is achieved by the features of claim 1 solved. Advantageous training and further education are described in claims 2 to 12.
  • a jack in a simple manner with an angled Support arm end can be provided.
  • the base body of the support arm from aluminum and the angle attachment, for example with a rotating Support plate is formed and therefore as a welded structure must be trained in steel.
  • the angle attachment made of plastic for example by spraying becomes.
  • Jack the simple construction of different series. Since the Angle attachment manufactured independently of the rest of the jack and can be stored, it is easily possible to use these with different Basic jack construction and vice versa to combine after the actual production. That means, that for example for a jack construction a given lifting height combines different angle attachments can be the different sill seam shapes or take into account different clearances.
  • the final assembly can be completed after the two Individual parts are made after painting.
  • the invention has another object based on a jack with the features of claim 7 in such a way that always the optimal position the jack is specified under the vehicle, where the maximum limit cases, loaded vehicle, defective tires and empty vehicle full of tires, find consideration and so that the load delivery point with respect to the contact point of the Jack remains in the friction cone.
  • Such jacks advantageously have an even greater variety on so that the number of jack body for a series can be reduced even more.
  • The is due to the fact that when the jack is placed on the Load delivery point is always optimally above the contact point.
  • Jacks usually have a foot 1 or a base plate 2 with which they stand on the ground 3.
  • the actual stand bodies can be designed differently his.
  • a support arm 4 over a horizontal pivot axis 5th is movably attached to the stand body.
  • a rigid or movable support receptacle 7 attached to a suitable location of the vehicle, preferably on the vehicle floor 8, or in an opening of the Vehicle engages.
  • Via a movement spindle 9, which a crank 10 is rotated Via a raising or lowering of the Free end 6 of the support arm 4 with respect to the base 3 reached.
  • Fig. 1 shows a single-arm jack.
  • the stand body this jack essentially consists of a mainstay 11, which is formed at the uprising end with a rigid foot 1 is.
  • the opposite end of the support leg 11 rotates a nut 12 with a moving spindle 9 interacts.
  • the support arm 4 is approximately in the center of the supporting leg 11 via a rotary joint 13, which has a horizontal pivot axis 5 forms, articulated.
  • the movement spindle 9 engages with her one end on the support arm 4. At the other end is the crank 10 appropriate.
  • the base body 14 is linear extends, an angle attachment 15 is attached.
  • This in turn carries a pivot pin 16 a Support mount 7, which is used to lift the vehicle under the sill 17 is applied. Due to the special shape of the Carrying receptacle 7 engages around the sill seam 18, whereby a perfect installation of the support receptacle 7 under the sill 17 is guaranteed.
  • the double articulated jack shown in Fig. 2 is opposite the one-arm jack shown in Fig. 1 much more complex designed.
  • the mainstay of this jack is 11 compared to the surface 3 with a rotating foot a base plate 2 supported what the surface pressure to the ground 3 significantly reduced.
  • the support arm 4 is here in the area the nut 12 for the movement spindle 9 at the upper end of the main leg 11 articulated to this.
  • the lifting movement that is initiated via the movement spindle 9 and the crank 10, is articulated accordingly to the pillar 11 and the Support arm 4 connected parallelogram rods 19 transmitted.
  • the Base body 14 of the support arm 4 is corresponding in the training Fig. 2 formed as a U-shaped sheet metal part, wherein the bottom 20 is directed outwards.
  • Angle attachment 15 and base body 14 of the support arm 4 are in the 2 achieved in that a rib 21 in engages a transverse slot 22 of the bottom 20 of the base body 14.
  • the angle attachment 15 engages at the free end 6 of the base body 14 of the support arm 4 between the lateral legs 23 of the sheet profile.
  • An attachment rivet 24 forms an additional one Fastening and position fixing between angle attachment 15 and Basic body 14.
  • the angle attachment 15 carries a rotatably connected support receptacle 7.
  • Fig. 3 shows an embodiment of the formation of an angle attachment 15 and its connection to the free end 6 of Base body 14 of the support arm 4 for the formation of a support arm 4 corresponding to FIG. 1.
  • the base body 14 of the support arm 4 is also formed here as a U-shaped sheet metal part.
  • the angle attachment 15 is at this training also formed as a sheet metal part, which also has a basically U-shaped cross section.
  • the side legs 25 are connected to one another by a base 26 connected.
