"Jack" j

i The invention relates to a jack, in the 4th

special swivel arm lifters where the j Swivel arm with actuation of a drive means, in particular a spindle, lifted and is lowered and this at its free end a the lower body outer wall in the Has threshold area reaching under lifting piece, the surface of which is the overlying The exterior wall of the body can be shifted in terms of shape

is adapted. In all types of jacks of this type, the lifting piece has on its upper wing a groove or notch for receiving a position lock effecting agent on the underside of the body. In many vehicle models there are downward-facing sides at the bottom Ribs, beads or dotted together

Sheet metal flanges on which the jack with the lifting piece is attached accordingly. When the jack is attached, this results in a certain amount of guidance. The lifter is standing when placing it approximately perpendicular to the body floor.

In the previous rigid formation of the lifting piece with its groove or another Recording execution at the end of the support arm results, for example, caused by the circular movement of the same in the direction of the two arrows is a very obtuse angle the groove, thus an approximately vertical, rib-shaped sheet metal flange or web the body is not bent and thus not damaged. Se bigger but the angle The recording is easier can occasionally the carriage sideways if the lifting process is carried out inappropriately slip and cause an accident. So there is a specific need that ^ receiving opening the cross-section of the engaging To adapt the part as precisely as possible.

The invention is based on the object of ensuring that the receiving width is kept narrow can be and still damage the web taken up by it

the point of sale is excluded by the lifting piece below the body and that the upper surface of the lifting piece from the moment the jack is attached during its entire up and down movement with i the entire area on the lower body wall rests.

According to the invention this object is achieved in that the lifting piece at the free end of the Swivel arm dürart is attached to him by a horizontal joint and so under the The action of a return organ, e.g. a tension or compression spring, means that it is during the entire pivoting movement of the swivel arm in the angular direction "ß" its in relation to the attachment point on the body wall maintains an upward position and as a result the supporting surface of the lifting piece during its entire up and down movement fits snugly against this over its entire length and width. Oa the jack very substantial Has to carry weights of the car, it is of great importance that the forces * load between the two touching surfaces of the exterior wall of the body and the upper

In a preferred embodiment, have

the lifting piece and the support arm each have a short projection on the corresponding side Suspension hole or the like to fix the retaining ends of a tension spring, which is always therefor ensures that the lifting piece in its lower position is parallel to the lower surface of the outer skin of the carrousel runs. In a preferred embodiment, there is also the swivel arm at least in its free front area from two spaced-apart sheet iron bars, which receives the pivot for the joint bore of the lifting piece, the SeJteawand either on the facing Inner surfaces of these two swivel rods bear leading or over the outer edges of the two support rods overlap their outer walls in a U-shape.

It is also advantageous if the swivel

movement of the Hubstückes to the outside by a corresponding projection of the side \ wall is limited by said outer facing him so in both pivoting directions: rand stopped as a stop and is. j

In the drawing, the subject matter of the invention is based on several exemplary embodiments shown by a jack.

Show it:

The middle V-shaped incision 3 is used

as a receptacle for the downward web-like projection 6 ^{a of} the lower body wall 6 in the threshold area, which is clearly visible in the lower and upper layers. It is further seen that the Hubstück 3 its wide-area contact takes and opposite the lower surface of the KarrAsserie 6 maintains jsodaß the web 6 ^a no injury experienced by bending can, regardless of whether the movement of the Tragarmesi angularly ß up or is downward. _;

In Fig. 7, 7 ^a has the Hubstück 3 approxi- j shirt the same configuration as shown in Fig, 4 and 5. This also applies to the formation

In the embodiment according to Fig. 8, 8 ^{a that} is

Lifting piece 3 designed very similarly. The Karf

It should be added that the surface of the lifting piece 3 facing the body also an elastic layer of rubber corresponds to
